ESSA Pharma Inc.

Attention: David Parkinson, Chief Executive Officer

Dear Sir:

ESSA Pharma Inc. (the “Corporation”) and Bloom Burton Securities Inc. (the “Agent”) are parties to an amended and restated agency agreement dated January 2, 2018 (the “Original A&R Agreement”). The Corporation and the Agents have agreed to amend and restate the Original A&R Agreement in its entirety, so that the respective duties, rights, and obligations of the parties with respect to each other and to the Offering (as defined herein), shall be governed by this Agreement (as defined herein).

The Agent understands that the Corporation proposes to issue and sell up to 125,000,000 Common Shares (as defined herein) (the “Offered Shares”) at a purchase price of US$0.20 per Offered Share (the “Offering Price”) for aggregate gross proceeds of up to US$25 million. In lieu of an Offered Share, purchasers may elect to purchase one pre-funded Common Share purchase warrant (a “Warrant”) at the Offering Price. Each Warrant will entitle the holder thereof to acquire, subject to adjustment in certain circumstances, one Common Share (a “Warrant Share”) until 4:30 p.m. (Toronto time) on the date that is 60 months following the issuance date thereof. The exercise price of the Warrants will be pre-funded except for a nominal exercise price of US$0.0001 per Warrant Share. The Agent also understands and acknowledges that the Corporation will complete the Concurrent Offering (as defined herein) contemporaneously with the closing of the first tranche of the Offering.

In addition, the Corporation hereby grants to the Agent an option (the “Over-Allotment Option”), exercisable in whole or in part, subject to approval by the Corporation, at any time and from time to time up to January 17, 2018, to arrange for the purchase from the Corporation of up to that number of additional Offered Shares (the “Additional Shares”) or Warrants (the “Additional Warrants” and together with the Additional Shares, the “Additional Securities”) as is equal to 15% of the Offered Securities (as defined herein) issued on the Closing Date (as defined herein) on the same basis as the Offered Securities to cover the Agent’s over-allocation position, if any, and for market stabilization purposes. Unless otherwise specifically referenced or unless the context otherwise requires, all references to: (i) “Offered Shares” shall include the Additional Shares; (ii) “Warrants” shall include the Additional Warrants; and (iii) “Offered Securities” shall include the Additional Securities. If the Agent elects to exercise the Over-Allotment Option, the Agent shall notify the Corporation in writing not later than January 17, 2018, which notice shall specify the number of Additional Securities requested to be sold under the Offering (as defined herein) pursuant to the exercise of the Over-Allotment Option and the date upon which such Additional Securities would be purchased (the “Over-Allotment Option Closing Date”). The Corporation shall notify the Agent in writing not later than two Business Days (as defined herein) following receipt of the Agent’s notice of exercise as to whether the Corporation approves the exercise of the Over-Allotment Option and shall confirm the Over-Allotment Option Closing Date if so approved. Such date may be the same as the Closing Date, but otherwise not earlier than the date of the Corporation’s notice. The offering of the Offered Securities (including, for greater certainty, any Additional Securities issued in connection with the exercise of the Over-Allotment Option) by the Corporation is hereinafter referred to as the “Offering”.

The Offered Securities may be offered to purchasers resident in each of the provinces of Alberta, British Columbia and Ontario, and such other jurisdictions as the Agent, with the consent of the Corporation, may designate prior to the Closing Date and the Over-Allotment Option Closing Date, as the case may be (the “Public Selling Jurisdictions”), on a public offering basis. Furthermore, the Offered Securities may be offered to purchasers resident in the United States and such other jurisdictions as the Agent, with the consent of the Corporation, may designate prior to the Closing Date and the Over-Allotment Option Closing Date, as the case may be (the “Private Selling Jurisdictions”), on a private placement basis. The Public Selling Jurisdictions and the Private Selling Jurisdictions are collectively referred to as the “Selling Jurisdictions”. The Agent is entitled to appoint a soliciting dealer group consisting of other registered dealers acceptable to the Corporation for the purposes of arranging for purchasers of the Offered Securities.

which, in the reasonable opinion of the Agent, prevents or restricts trading in the Shares or the distribution of the Offered Securities; or

- 30 -

| (iii) | there should develop, occur or come into effect or existence any event, action, state, condition or major financial occurrence or catastrophe of national or international consequence or any law or regulation or a change thereof which, in the reasonable opinion of the Agent, materially adversely affects or involves, or will materially adversely affect or involve, the financial markets or the business, operations or affairs of the Corporation, taken as a whole;

| (iv) | the state of the financial markets in Canada and the United States is such that, in the reasonable opinion of the Agent, the Offered Securities cannot be marketed profitably;

| (v) | there is an inquiry or investigation (whether formal or informal) by any securities regulator or other regulatory authority in relation to the Corporation or any one of its directors or officers, or any of its principal shareholders, which has not been rescinded, revoked or withdrawn and which, in each case, operates to materially prevent or restrict the Distribution of the Offered Securities as contemplated by this Agreement;

The rights of termination contained in this Section 12 are in addition to any other rights or remedies the Agent may have in respect of any default, act or failure to act or non-compliance by the Corporation in respect of any of the matters contemplated by this Agreement or otherwise. In the event of any such termination, there shall be no further liability on the part of the Agent to the Corporation or on the part of the Corporation to the Agent except in respect of any liability which may have arisen prior to or arise after such termination under any of Sections 13 and 15.

13. | Indemnity

The Corporation agrees to indemnify and save harmless the Agent and the U.S. Agent and their affiliates, and each of their respective directors, officers, employees, shareholders, partners, agents and advisors (collectively, the “Indemnified Parties” and each, an “Indemnified Party”), from and against any and all losses (except loss of profit), claims, actions, suits, proceedings, damages, liabilities or expenses of whatsoever nature or kind, including the aggregate amount paid in reasonable settlement of any actions, suits, proceedings, investigations or claims and the reasonable, actual and accountable fees and expenses of their counsel in connection with any action, suit, proceeding, investigation or claim that may be made or threatened against any Indemnified Party or in enforcing this indemnity (collectively, the “Claims”) to which an Indemnified Party may become subject or otherwise involved in any capacity insofar as the Claims relate to, are caused by, result from, arise out of or are based upon, directly or indirectly, the performance of professional services rendered to the Corporation by an Indemnified Party hereunder or otherwise in connection with the matters referred to in this Agreement, whether performed before or after the Corporation’s execution of this Agreement, and further agrees to immediately reimburse each Indemnified Party forthwith, upon demand, for any legal or other expenses reasonably incurred by such Indemnified Party in connection with any Claim.

- 31 -

The Corporation also agrees that no Indemnified Party shall have any liability (either direct or indirect, in contract or tort or otherwise) to the Corporation or any person asserting Claims on the Corporation’s behalf or in right for or in connection with the performance of professional services rendered to the Corporation by an Indemnified Party hereunder or otherwise in connection with the matters referred to in this Agreement, whether performed before or after the Corporation’s execution of the Agreement, except to the extent that any losses, expenses, Claims, actions, damages or liabilities incurred by the Corporation are determined by a court of competent jurisdiction in a final judgement that has become non-appealable to have resulted from the Indemnified Party’s breach of this Agreement, or the gross negligence, wilful misconduct or fraud of such Indemnified Party.

In the event and to the extent that a court of competent jurisdiction in a final judgement that has become non-appealable determines that an Indemnified Party breached this Agreement, or was grossly negligent or guilty of wilful misconduct or fraud in connection with a Claim in respect of which the Corporation has advanced funds to the Indemnified Party pursuant to this indemnity, such Indemnified Party shall immediately reimburse such funds to the Corporation and thereafter this indemnity shall not apply to such Indemnified Party in respect of such Claim.

The Corporation agrees to waive any right the Corporation might have of first requiring the 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.

In case any Claim is brought against an Indemnified Party, or an Indemnified Party has received notice of the commencement of any investigation in respect of which indemnity may be sought against the Corporation, the Indemnified Party will give the Corporation prompt written notice of any such Claim or investigation of which the Indemnified Party has knowledge and the Corporation will undertake the investigation and defence thereof on behalf of the Indemnified Party, including the prompt employment of counsel acceptable to the Indemnified Parties affected and the payment of all expenses. Failure by the Indemnified Party to so notify shall not relieve the Corporation of its obligation of indemnification hereunder unless (and only to the extent that) such failure results in the forfeiture by the Corporation of substantive rights or defences or the extent that the Corporation is materially prejudiced thereby.

No admission of liability and no settlement, compromise or termination of any Claim shall be made without the Corporation’s consent and the consent of the Indemnified Parties affected, such consents not to be unreasonably withheld.

Notwithstanding that the Corporation will undertake the investigation and defence of any Claim, an Indemnified Party will have the right to employ separate counsel with respect to any Claim and participate in the defence thereof, but the fees and expenses of such counsel will be at the expense of the Indemnified Party unless:

| (a) | the employment of such counsel has been authorized in writing by the Corporation;

| (b) | the Corporation has not assumed the defence within a reasonable period of time after receiving notice of such Claim;

| (c) | the named parties to any such Claim include both the Corporation and the Indemnified Party and the Indemnified Party shall have been advised by counsel in writing that there may be a conflict of interest between the Corporation and the Indemnified Party; or

| (d) | the Indemnified Party has been advised in writing by counsel that there are one or more defences available to the Indemnified Party which are different from or in addition to those available to the Corporation, which makes representation by the same counsel inappropriate.

- 32 -

The rights accorded to the Indemnified Parties hereunder shall be in addition to any rights an Indemnified Party may have at common law or otherwise.

If for any reason the foregoing indemnification is unavailable (other than in accordance with the terms hereof) to the Indemnified Parties (or any of them) or insufficient to hold them harmless, then the Corporation shall contribute to the amount paid or payable by the Indemnified Parties as a result of such Claim in such proportion as is appropriate to reflect not only the relative benefits received by the Corporation on the one hand and the Indemnified Parties on the other hand, but also the relative fault of the Corporation and the Indemnified Parties, as well as any other equitable considerations which may be relevant; 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 amount in excess of the fees actually received by the Indemnified Parties hereunder in which case such fees and expenses will be for the Corporation’s account.

The Corporation hereby acknowledges the Agent as trustee for each of the other Indemnified Parties of the Corporation’s covenants under this indemnity with respect to such persons and the Agent agrees to accept such trust and to hold and enforce such covenants on behalf of such persons.

The Corporation agrees to immediately reimburse the Agent monthly for the time spent by an Indemnified Party in connection with any Claim at their reasonable per diem rates. The Corporation also agrees that if any Claim shall be brought against, or an investigation commenced in respect of the Corporation or the Corporation and the Indemnified Parties shall be required to testify, participate or respond in respect of or in connection with the performance of professional services rendered to the Corporation by an Indemnified Party hereunder or otherwise in connection with the matters referred to in this Agreement, the Agent shall have the right to employ its own counsel in connection therewith and the Corporation will immediately reimburse the Agent monthly for the time spent by an Indemnified Party in connection therewith at their reasonable per diem rates together with such fees and disbursements and reasonable, actual and accountable expenses as may be incurred, including the fees and disbursements of the Agent’s counsel.

14. | Severability

If any provision of this Agreement is determined to be void or unenforceable in whole or in part, it shall be deemed not to affect or impair the validity of any other provision of this Agreement and such void or unenforceable provision shall be severable from this Agreement.

15. | Expenses

Out of the proceeds of the Offering, the Corporation shall pay all expenses and fees in connection with the Offering, including all expenses of or incidental to the issue, sale or Distribution of the Offered Securities; the fees and expenses of the Corporation’s counsel; and all costs incurred in connection with the preparation of documents relating to the Offering. The Corporation shall also pay all legal expenses and fees incurred by the Agent, which shall include the reasonable fees of Baker & McKenzie LLP, counsel for the Agent and U.S. Agent, up to a maximum of US$75,000 plus disbursements and taxes, and all reasonable out-of-pocket expenses of the Agent provided that such costs claimed by the Agent shall not exceed US$25,000 plus disbursements and taxes. However, that such reimbursement amount in no way limits or impairs the indemnification and contribution provisions of this Agreement. In the event the Closing does not occur, all fees and expenses incurred by the Agent shall be payable by the Corporation immediately upon receiving an invoice therefor from the Agent.

- 33 -

16. | Survival of Representations and Warranties

The representations, warranties, covenants, obligations and agreements of the Corporation contained in this Agreement and in any certificate delivered pursuant to this Agreement or in connection with the purchase and sale of the Offered Securities shall survive the purchase of the Offered Securities and shall continue in full force and effect for a period of three years following the Closing Date regardless of any subsequent disposition of the Offered Securities by the investors or the termination of the Agent’s obligations and shall not be limited or prejudiced by any investigation made by or on behalf of the Agent in connection with the sale of the Offered Securities.

17. | Conflict of Interest

The Corporation acknowledges that the Agent and its affiliates carry on a range of businesses, including providing stockbroking, investment advisory, research, investment management and custodial services to clients and trading in financial products as agent or principal. It is possible that the Agent and other entities in its group that carry on those businesses may hold long or short positions in securities of companies or other entities, which are or may be involved in the transactions contemplated in this Agreement and effect transactions in those securities for their own account or for the account of their respective clients. The Corporation agrees that these divisions and entities may hold such positions and effect such transactions without regard to the Corporation’s interests under this Agreement.

18. | Time of the Essence

Time shall be of the essence of this Agreement.

19. | Fiduciary

The Corporation hereby acknowledges that the Agent is acting solely as agent in connection with the offer and sale of the Offered Securities. The Corporation further acknowledges that the Agent is acting pursuant to a contractual relationship created solely by this Agreement entered into on an arm’s length basis, and in no event do the parties intend that the Agent act or be responsible as a fiduciary to the Corporation, its management, shareholders or creditors or any other person in connection with any activity that the Agent may undertake or have undertaken in furtherance of such offer and sale of the Corporation’s securities, either before or after the date hereof. The Agent hereby expressly disclaims any fiduciary or similar obligations to the Corporation, either in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions, and the Corporation hereby confirms its understanding and agreement to that effect. The Corporation and the Agent agree that they are each responsible for making their own independent judgments with respect to any such transactions and that any opinions or views expressed by the Agent to the Corporation regarding such transactions, including any opinions or views with respect to the price or market for the Corporation’s securities, do not constitute advice or recommendations to the Corporation. The Corporation and the Agent agree that the Agent is acting as principal and not the agents or fiduciaries of the Corporation and the Agent has not, and the Agent will not assume, any advisory responsibility in favour of the Corporation with respect to the transactions contemplated hereby or the process leading thereto (irrespective of whether the Agent has advised or is currently advising the Corporation on other matters). The Corporation hereby waives and releases, to the fullest extent permitted by law, any claims that the Corporation may have against the Agent with respect to any breach or alleged breach of any fiduciary duty to the Corporation in connection with the transactions contemplated by this Agreement.

Terms used herein have the meanings given to them in Regulation S.”
