ARRANGEMENT AGREEMENT

This Plan of Arrangement is made pursuant to and subject to the provisions of the Arrangement Agreement. At the Effective Time, the Arrangement shall be binding upon Stillwater, AcquireCo, Marathon, Marathon Gold and the Marathon Shareholders.

THE ARRANGEMENT

(a)

The Arrangement. At the Effective Time, the following shall occur and shall be deemed to have occurred in the following order without any further act or formality:

	(i)		The holders of the Marathon Options shall cease to be entitled to receive Marathon Shares upon the exercise thereof.

	(ii)		The Marathon Warrants, if outstanding immediately prior to the Effective Time, shall remain outstanding in accordance with their terms and will entitle the holder thereof to receive, upon exercise in accordance with the terms thereof, in lieu of the number of Marathon Shares otherwise issuable upon exercise thereof, the Cash Consideration, 0.112 of a Stillwater Share and 0.5 of a Marathon Gold Share for each Marathon Warrant so exercised, which the holder would have been entitled to receive as a result of the Arrangement and the other transactions contemplated herein if, immediately prior to the Effective Time, such holder had been the registered holder of the number of Marathon Shares to which such holder was entitled upon such exercise..

	(iii)		Marathon shall undertake a reorganization of capital within the meaning of section 86 of the Tax Act as follows, and in the following order:

The authorized capital of Marathon will be amended by:

	I.		re-designating the Marathon Shares as Class B Shares and each certificate representing such an outstanding Marathon Share shall, as and from the time such re-designation is effective, represent a Class B Share; and

	II.		the creation of an unlimited number of Class A Shares;

			and the articles of Marathon shall be deemed to be amended accordingly.

	B.		Each issued Class B Share held by a Dissenting Marathon Shareholder (for greater certainty, being a Marathon Shareholder who has complied with the Dissent Rights and is ultimately entitled to be paid for its Class B Shares) will be acquired by AquireCo in consideration for a debt claim against Stillwater to be paid fair value of such Class B Shares pursuant to the Dissent Procedures.

	C.		Each issued Class B Share, other than those held by Dissenting Marathon Shareholders, will be exchanged with Marathon for one Class A Share and 0.50 Marathon Gold Shares.

	D.		The stated capital of Marathon for the outstanding Class A Shares will be an amount equal to the stated capital of Marathon for the Class B Shares, less the fair market value of the Marathon Gold Shares distributed to Marathon Shareholders, other than Dissenting Marathon Shareholders pursuant to section 4 hereof and the paid-up capital of the Class A Shares of Marathon will be reduced accordingly.

	E.		The Class B Shares (including the Class B Shares held by Dissenting Marathon Shareholders and acquired by AcquireCo pursuant to paragraph 3(a)(iii)(B) hereof) will be cancelled.

	(iv)		Each Class A Share (other than Class A Shares held by Stillwater and its Affiliates and the Dissenting Shareholders) shall be transferred by the holder thereof to AquireCo (free and clear of any liens, charges or encumbrances of whatsoever nature), and each Former Marathon Shareholder (other than Stillwater and its Affiliates and the Dissenting Shareholders) shall be entitled to receive, in exchange therefor and subject to the following provisions of this Section 3, the Cash Consideration and the Share Consideration;

	(v)		Each Marathon Option outstanding immediately prior to the Effective Time, whether vested or not, shall be exchanged for a fully-vested option granted by Stillwater (each a “Stillwater Replacement Option” and collectively the “Stillwater Replacement Options”) to acquire that number of Stillwater Shares equal to the product of (A) the number of Marathon Shares subject to the Marathon Option immediately before the Effective Time and (B) the Exchange Ratio. The exercise price per Stillwater Share subject to any Stillwater Replacement Option shall be equal to the quotient of (A) the exercise price per Marathon Share subject to such Marathon Option immediately before the Effective Time divided by (B) the Exchange Ratio. Except as set out above, the terms of each Stillwater Replacement Option shall be the same as the Marathon Option exchanged therefor, but the expiry date shall be the same as if the holder of the Marathon Options had not ceased to be employed by Marathon.

	(vi)		With respect to each Class A Share:

	A.		each such Marathon Shareholder, other than Stillwater, shall cease to be the holder of such Class A Share on the Effective Date and such holder’s name shall be removed from the share register of Marathon as at the Effective Time; and

	B.		AcquireCo shall be deemed to be the transferee of such Class A Share (free and clear of any Encumbrance) on the Effective Date and AcquireCo shall be entered in the share register of Marathon as the holder thereof as at the Effective Time.

(b)

No Fractional Shares. Following the Effective Time, if the aggregate number of Stillwater Shares or Marathon Gold Shares to which an Marathon Shareholder would otherwise be entitled, or to which a holder of Stillwater Replacement Options or the Marathon Warrants is entitled on exercise or conversion (as the case may be) of Stillwater Replacement Options or the Marathon Warrants is not a whole number, then the number of Stillwater Shares or Marathon Gold Shares, as the case may be, shall be

			rounded down to the next whole number and no compensation will be paid to the Marathon Shareholder in respect of such fractional Stillwater Share or Marathon Gold Share, as the case may be.

	(c)		Fractional Cash Consideration. Any cash consideration owing to a Former Marathon Shareholder shall be rounded up to the next whole cent.

RIGHTS OF DISSENT

Marathon Shareholders shall be entitled to exercise dissent rights (“Dissent Rights”) with respect to the Marathon Shares pursuant to and in the manner set forth in section 190 of the CBCA as modified by the Interim Order and this section 4. Notwithstanding subsection 190(a) of the CBCA, any Marathon Shareholder seeking to exercise Dissent Rights must deliver to Marathon a written objection to the Arrangement by 5:00 p.m. (Toronto time) on the Business Day immediately prior to the date of the Marathon Meeting and must strictly comply with all other provisions of section 190 of the CBCA as modified by the Interim Order (the “Dissent Procedures”).

If the Arrangement is concluded, a Marathon Shareholder who exercises Dissent Rights in strict compliance with the Dissent Procedures shall be entitled to be paid by Marathon the fair value of the Marathon Shares held by such Dissenting Marathon Shareholder in respect of which such Dissenting Marathon Shareholder dissents, determined as provided for in the CBCA, as modified by the Interim Order and this section 4. Any such Dissenting Marathon Shareholder who exercises Dissent Rights and who:

	(a)		is ultimately entitled to be paid fair value for its Marathon Shares shall be deemed to have transferred its Marathon Shares to Stillwater in consideration for a debt claim against Stillwater to be paid fair value of such shares pursuant to the Dissent Procedures, and shall not be entitled to any other payment or consideration, including any payment under the Arrangement had such holders not exercised their Dissent Rights; or

	(b)		is for any reason ultimately not entitled to be paid for fair value for its Marathon Shares, shall be deemed to have participated in the Arrangement as of the Effective Time at the same terms and at the same time as a non-dissenting Marathon Shareholder and shall be issued only the same consideration which a Marathon Shareholder is entitled to receive under the Arrangement as if such Dissenting Marathon Shareholder would not have exercised Dissent Rights.

		In no case shall Stillwater, AquireCo, Marathon or Marathon Gold be required to recognize Dissenting Marathon Shareholders or a Dissenting Marathon Shareholder at and after the Effective Time as a legal or beneficial holder of Marathon Shares for any purpose, and the names of such Dissenting Marathon Shareholders shall be removed from the share register of Marathon at the Effective Time.

5.		DELIVERY OF STILLWATER SHARES AND CASH AND MARATHON GOLD SHARES

(i)

	(iii)		After the Effective Time and until surrendered as contemplated by paragraph 5(c)(i) hereof, each certificate which immediately prior to the Effective Time represented one or more Marathon Shares shall be deemed at all times to represent only the right to receive in exchange therefor a certificate representing

the Stillwater Shares and the Marathon Gold Shares and the Cash Consideration to which the holder of such certificate is entitled to receive in accordance with paragraph 5(c)(i) hereof.

When authorizing such delivery of certificates representing the Stillwater Shares and the Marathon Gold Shares which such Marathon Shareholder is entitled to receive in exchange for such lost, stolen or destroyed certificate, the Marathon Shareholder to whom certificates representing such Stillwater Shares and Marathon Gold Shares are to be delivered shall, as a condition precedent to the delivery of such Stillwater Shares and Marathon Gold Shares, give a bond satisfactory to Stillwater, AcquireCo, Marathon, Marathon Gold and the Depositary in such amount as Stillwater, AcquireCo, Marathon, Marathon Gold and the Depositary may direct, or otherwise indemnify Stillwater, AcquireCo, Marathon, Marathon Gold and the Depositary in a manner satisfactory to Stillwater, AcquireCo, Marathon, Marathon Gold and the Depositary, against any claim that may be made against Stillwater, AcquireCo, Marathon, Marathon Gold or the Depositary with respect to the certificate alleged to have been lost, stolen or destroyed and shall otherwise take such actions as may be required by the by-laws of Stillwater, AcquireCo, Marathon and Marathon Gold as the case may be.

Subject to Applicable Law and to section 5 hereof, at the time of such compliance, there shall, in addition to the delivery of a certificate representing the Stillwater Shares and the Marathon Gold Shares to which such holder is thereby entitled, be delivered to such holder, without interest, the amount of the dividend or other distribution with a record date after the Effective Time theretofore paid with respect such Stillwater Shares and Marathon Gold Shares.

	(f)		Termination of Rights. Any certificate formerly representing Marathon Shares that is not deposited, with all other documents as provided in this section 5 on or before the sixth anniversary of the Effective Date, shall cease to represent any claim or interest of any kind or nature (including, without limitation dividends or distributions set out in section 5(d) hereof) against Stillwater, AcquireCo, Marathon, Marathon Gold or the Depositary.

	(g)		Withholding Rights. Stillwater, AcquireCo, Marathon, Marathon Gold and the Depositary shall be entitled to deduct and withhold from all dividends or other distributions otherwise payable to any Marathon Shareholder such amounts as Stillwater, Marathon, Marathon Gold or the Depositary is required or permitted to deduct and withhold with respect to such payment under the Tax Act, the United States Internal Revenue Code of 1986 or any provision of any applicable federal, provincial, state, local

or foreign tax law, in each case, as amended.
