Marathon, Marathon Gold or any of the Marathon Subsidiaries to conduct its business in all material
respects as it has been carried on prior to the date hereof, or that would or could materially

participate, directly or indirectly, in any discussions or negotiations with, or provide
information to, or permit any visit to the properties or facilities of Marathon, Marathon Gold or
any of the Marathon Subsidiaries, subject to the execution by such Person of the confidentiality
agreement as described above, provide such Person with such information and access; provided that
Marathon sends a copy of any such confidentiality agreement to Stillwater promptly upon its
execution and Stillwater is provided with a list of, and a copy of, the information provided to
such Person (if not previously provided with such information) and is immediately provided with
access to similar information to which such Person is provided (if not previously provided with
such access).

	 	(d)	 	From and after the date of this Agreement, Marathon shall promptly (and in any event within 24

inquiry or offer as Stillwater may reasonably request. Marathon shall keep Stillwater fully
informed on a prompt basis of the status, including any change to the material terms, of any such
inquiry, proposal or offer.

45.

action prohibited by subsection 4.2(b)(iii), if the Marathon Board determines, in good faith (after
consultation with outside legal counsel) that such action or inaction is necessary for the Marathon
Board to act in a manner consistent with its fiduciary duties or Applicable Laws, provided that
Marathon may not proceed with the announcement of such decision before giving written notice of
such decision to Stillwater. The foregoing shall not relieve Marathon from its obligation to

Meeting to a date that is not less than five Business Days and not more than 10 Business Days after
the date of receipt by Stillwater of the Superior Proposal Notice.
	 
	 	(b)	 	During the five Business Day period referred to in paragraph 4.3(a)(ii) above, Stillwater shall
have the right, but not the obligation, to offer to amend the terms of this Agreement. The Marathon
Board will review any proposal by Stillwater to amend the terms of
this Agreement in good faith in
order to determine whether Stillwater’s amended proposal upon acceptance by Marathon would result
in such Superior Proposal ceasing to be a Superior Proposal. If the Marathon Board so determines,
Marathon shall enter into an amended agreement with Stillwater reflecting Stillwater’s amended
proposal. If the Marathon Board continues to believe, in good faith and after consultation with the
Financial Advisor and outside legal counsel, that such Superior Proposal remains a Superior
Proposal and therefore rejects Stillwater’s amended proposal, Marathon may, on termination of this
Agreement in accordance with section 7.1 hereof and payment of the Termination Fee as required
pursuant to section 7.3 hereof, accept, approve, recommend or enter into an agreement,
understanding or arrangement in respect of such Superior Proposal.
	 
	 	(c)	 	Marathon and Marathon Gold hereby acknowledge and agree that each successive material
modification of any Acquisition Proposal shall constitute a new Acquisition Proposal for purposes
of section 4.2 hereof and the requirement under paragraph 4.3(a)(ii) hereof to initiate an
additional five Business Day notice period.
	 
	 	(d)	 	If the Marathon Information Circular has been sent to the Marathon Shareholders prior to the
expiry of the five Business Day period set forth in subsection 4.3(a) hereof and, during such
period, Stillwater requests in writing that the Marathon Meeting proceed, unless otherwise ordered
by the Court, Marathon shall continue to take all reasonable actions necessary to hold the Marathon
Meeting and to cause the Arrangement to be voted on at the Marathon Meeting provided that such
obligation shall cease to apply upon termination of this Agreement in accordance with section
7.1 hereof and payment of the Termination Fee, if applicable, pursuant to section 7.3 hereof.

shall be entitled to terminate this Agreement under this section 7.2 until the expiration of such
Revised Termination Deadline.

	7.3	 	If:

	 	(a)	 	Stillwater shall terminate this Agreement pursuant to subsection 7.1(b) hereof;
	 
	 	(b)	 	Marathon shall terminate this Agreement pursuant to subsection 7.1(d) hereof;
	 
	 	(c)	 	either Marathon or Stillwater shall terminate this Agreement pursuant to subsection 7.1(e)
hereof in circumstances where the Arrangement Resolution has not received the required Marathon
Shareholders Approval at the Marathon Meeting and (i) a bona fide Acquisition Proposal has been
publicly announced or made by any Person other than Stillwater prior to the Marathon Meeting and
not publicly withdrawn more than five Business Days prior to the Marathon Meeting, and (ii)
Marathon enters into an agreement with respect to such Acquisition Proposal, or such Acquisition
Proposal is completed, after the date of this Agreement and prior to the expiration of 12 months
following the termination of this Agreement;
	 
	 	(d)	 	Stillwater shall terminate this Agreement pursuant to
subsection 7.1(f) hereof; or
	 
	 	(e)	 	Stillwater shall terminate this Agreement pursuant to subsection 7.1(g) hereof;

obligated to make more than one payment pursuant to this section 7.3. Marathon hereby acknowledges
that the payment amount set out in this section 7.3 is a payment of liquidated damages which are a
genuine pre-estimate of the damages which Stillwater will

58.

 

	 	 	suffer or incur as a result of the event giving rise to such damages and the resultant non-completion of the Arrangement and is not a penalty. Marathon hereby irrevocably waives any right it
may have to raise as a defence that any such liquidated damages are excessive or punitive.

	7.4	 	This Agreement and the Plan of Arrangement may, at any time and from time to time before or
after the holding of the Marathon Meeting but not later than the Effective Time, be amended by
mutual written agreement of the Parties hereto, and any such amendment may, subject to the Interim

	 	(a)	 	change the time for the performance of any of the obligations or acts of any of the Parties
hereto;
	 
	 	(b)	 	waive any inaccuracies or modify any representations or warranty contained herein or in any
document delivered pursuant hereto;
	 
	 	(c)	 	waive compliance with or modify any of the covenants herein contained and waive or modify the
performance of any of the obligations of any of the Parties hereto; or
	 
	 	(d)	 	waive compliance with or modify any mutual conditions precedent herein contained.

Waiver

	7.5	 	At any time prior to the Effective Date, any Party hereto may:

	 	(a)	 	extend the time for the performance of any of the obligations or other acts of the other
Parties hereto; or
	 
	 	(b)	 	waive compliance with any of the covenants or agreements of the other Parties hereto or with
any conditions to its own obligations, but in each case only to the extent such obligations,
agreements and conditions are intended for its benefit.

ARTICLE 8

Other Business

	8.1	 	Following the Effective Date, Marathon Gold and Stillwater shall have the right without
consulting or notifying the other to engage in and receive full benefits from other and independent
business activities, whether or not competitive or in conflict with the transactions contemplated
in this Agreement. The doctrine of “corporate opportunity” or “business opportunity” shall not be
applied to any other transaction, activity, venture or operation of Marathon Gold or Stillwater not
within the boundaries or in respect of the Acquired Properties and, except as otherwise expressly
provided in other agreements between Marathon Gold and Stillwater, if any, neither of Marathon Gold
or Stillwater shall have any duty to the other with respect to any opportunity to acquire property
outside of the boundaries of the Acquired Properties.

59.

 

Right to Purchase Marathon Gold Shares

	8.2	 	Marathon Gold covenants with Stillwater that from and after the Effective Date, in connection
with an initial equity offering which Marathon Gold may undertake following the Effective Date,
Stillwater shall have the right but not the obligation to purchase from Marathon Gold at the
offering price per Marathon Gold Share under such offering, that number of Marathon Gold Shares
equal to 15% of the total Marathon Gold Shares outstanding following the completion of the equity
offering, which covenant shall be set forth in an agreement from Marathon Gold to be delivered to
Stillwater on the Effective Date. Such agreement shall also contain covenants from Stillwater to
provide 5 business days prior written notice of any intention to acquire, directly or indirectly,
securities that would cause Stillwater to beneficially own more than 15% of any class of voting
securities of Marathon Gold and to give Marathon Gold 60 days to exercise a right of first refusal
to find purchasers of any Marathon Gold securities that Stillwater intends to sell.

Post-Closing Adjustments

	8.3	 	For a period of two years following the Effective Date, to the extent that Stillwater and
Marathon Gold determine, after the Effective Date, that the occurrence of any circumstance or event
which requires a post-closing adjustment by the Parties hereto, the Parties hereto will work
together to determine a mutually acceptable tax-efficient manner to effect, to the greatest extent
possible, the necessary transfers and will, in any event, effect the necessary transfers and make
any payments or reimbursements related thereon, as the case may be within 15 calendar days after
the determination of any such adjustments by cheque or wire transfer to the Party hereto to whom
such payments or reimbursements are payable or owed.

Indemnification by Marathon Gold

	8.4	 	From the Effective Time, Marathon Gold hereby agrees to indemnify and save harmless Stillwater,
Marathon and the Marathon Subsidiaries from all Losses suffered or incurred by Stillwater, Marathon
or the Marathon Subsidiaries as a result of or arising directly or indirectly out of or in
connection with (a) any Indemnified Liability; or (b) any Indemnified Taxes, unless they are the
result of actions taken at the request of Stillwater or after the Effective Date.
	 
	 	 	If any claim, proceeding or other matter resulting from the occurrence of any of the events
contemplated by subsection 8.4 above (a “Claim”) is made against Stillwater, Marathon or the
Marathon Subsidiaries by a third party for which Stillwater, Marathon or the Marathon Subsidiaries
may be entitled to indemnification, Stillwater or Marathon or the Marathon Subsidiaries, as
applicable, shall give notice (the “Indemnity Notice”) to Marathon Gold specifying the particulars
of such Claim within 60 days after it receives notification of the Claim. Marathon Gold shall have
the right to participate in any negotiations or proceedings with respect to such Claim. Stillwater,
Marathon or the Marathon Subsidiaries, as applicable shall not settle or compromise any such Claim
without the prior written consent of Marathon Gold, unless Marathon Gold has not, within five
Business Days after the giving of the Indemnity Notice, given notice to Stillwater, Marathon or the
Marathon Subsidiaries, as applicable, that it wishes to dispute such Claim. If Marathon Gold does
give such a notice, it shall have the right to assume the defence of such Claim and to defend such
Claim in the name of Stillwater, Marathon or the Marathon Subsidiaries, as applicable. Stillwater,
Marathon and the Marathon Subsidiaries shall provide to Marathon Gold all files, books, records and
other information in its possession or control which may be relevant to the defence of such Claim.
Stillwater and Marathon shall co-operate in all reasonable respects in the defence of such Claim. If
Marathon Gold fails after the giving of such notice, diligently and reasonably to defend such Claim
throughout the period that

60.

 

	 	 	such Claim exists, its right to defend the Claim shall terminate and Stillwater, Marathon or the
Marathon Subsidiaries may assume the defence of such Claim. In such event, Stillwater, Marathon or
the Marathon Subsidiaries may compromise or settle such Claim without the consent of Marathon Gold.
	 
	 	 	Notwithstanding anything to the contrary, in the event that the Claim relates to Indemnified Taxes,
Marathon Gold’s indemnity hereunder shall be limited to the amount by which the aggregate sum of
all such Claims exceeds the aggregate sum of unexpired non-capital losses, cumulative Canadian
development expense and cumulative Canadian exploration expense of Marathon existing as at the end
of the taxation year which is deemed to end immediately before the
Effective Time (the “Tax
Indemnity Limit”). To the extent that the aggregate sum of all Claims relating to Indemnified Taxes
exceeds the Tax Indemnity Limit, Marathon Gold shall pay to Stillwater, Marathon or the Marathon
Subsidiaries, as the case may be, such excess upon the amount of Indemnified Taxes being finally
determined whether by assessment, reassessment or agreement with the Governmental Entity or by
judicial determination. If Stillwater, Marathon or the Marathon Subsidiaries, as the case may be,
shall receive a refund of any Indemnified Taxes in respect of which a payment was made by Marathon
Gold pursuant to this section 8.4 the amount of such refund shall forthwith be paid to Marathon
Gold, together with interest, if any, paid by the applicable Governmental Entity on such refund
(net of any taxes thereon).
	 
	 	 	If the amount of Indemnified Taxes imposed on or suffered by Stillwater, Marathon or the Marathon
Subsidiaries, as the case may be, as finally determined, is greater than the amount which was paid
by Marathon Gold to Stillwater, Marathon or the Marathon Subsidiaries, as the case may be, or to
any Governmental Entity on account of Indemnified Taxes, Marathon Gold shall, forthwith following
such final determination, pay the amount of such difference to Stillwater, Marathon or the Marathon
Subsidiaries, as the case may be, together with any interest which may be payable to a Governmental
Entity in respect of such amount.
	 
	 	 	For certainty, the Parties hereto acknowledge that a Claim in respect of Indemnified Taxes can be
made by Stillwater until the day which is 90 days immediately
following the later of: (1) the last
date on which an assessment can be made against Marathon in respect of any Indemnified Taxes, and
(2) the date on which the period for an appeal from an assessment or other determination of such
Tax liability, or decision of a court or other competent tribunal in respect thereof may be filed
has expired and that appeal has not been filed.

Remedies

	8.5	 	The Parties hereto acknowledge and agree that an award of money damages may be inadequate for
any breach of this Agreement by any Party hereto or its representatives and advisors and that such
breach may cause the non-breaching Party hereto irreparable harm. Accordingly, the Parties hereto
agree that, in the event of any such breach or threatened breach of this Agreement by one of the
Parties hereto, Stillwater (if either Marathon or Marathon Gold is the breaching Party) or Marathon
and Marathon Gold (if Stillwater is the breaching Party) will be entitled, without the requirement
of posting a bond or other security, to seek equitable relief, including injunctive relief and
specific performance. Subject to any other provision hereof including, without limitation, section
7.3 hereof, such remedies will not be the exclusive remedies for any breach of this Agreement but
will be in addition to all other remedies available hereunder or at law or in equity to each of the
Parties hereto.

2. 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.

3. 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.
	 
	 	(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:

	 	A.	 	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.

76.

 

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

	 	(ii)	 	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;
	 
	 	(iv)	 	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.
	 
	 	(v)	 	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.

77.

 

	4.	 	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 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

	 	(a)	 	Deposit. At or prior to the Effective Time:

	 	(i)	 	Marathon shall deposit with the Depositary, for the benefit of the Former Marathon
Shareholders, certificate(s) representing the Marathon Gold Shares;
	 
	 	(ii)	 	AquireCo shall deposit with the Depositary, for the benefit of the Former
Marathon Shareholders, cash in an amount equal to the Maximum Cash; and

Shareholders, certificate(s) representing the Maximum Shares.

78.

 

	 	(b)	 	Letter of Transmittal. The Depositary will forward to each Marathon Shareholder, at the address
of such Marathon Shareholder as it appears on the register for Marathon Shares, a Letter of
Transmittal and instructions for obtaining delivery of the certificates representing the Marathon
Gold Shares and the Stillwater Shares allotted and issued to such Marathon Shareholder pursuant to
the Arrangement.
	 
	 	(c)	 	Entitlement to Marathon Gold Certificates and Stillwater Certificates and cash.

	 	(i)	 	Stillwater, AcquireCo and Marathon shall cause the Depositary, as soon as
practicable following the later of the Effective Date and the date of deposit with the Depositary
of a duly completed Letter of Transmittal and the certificates representing the Marathon Shares
or other documentation as provided in the Letter of Transmittal, to:

	 	A.	 	forward or cause to be forwarded by first class mail (postage prepaid) to the Former Marathon
Shareholders at the address specified in the Letter of Transmittal; or
	 
	 	B.	 	if requested by the Former Marathon Shareholders in the Letter of Transmittal, make available at
the Depositary for pick-up by the Former Marathon Shareholders; or
	 
	 	C.	 	if the Letter of Transmittal neither specifies an address nor contains a request as described in
(ii), forward or cause to be forwarded by first class mail (postage prepaid) to the Former Marathon
Shareholders at the address of such Former Marathon Shareholders as shown on the share register
maintained by Marathon as at the Effective Time,

	 	 	 	certificates representing the Marathon Gold Shares issuable to such Former Marathon Shareholders
and a cheque representing the cash payment, if any, payable to such Former Marathon Shareholders
and/or certificates representing the number of Stillwater Shares, if any, issuable to such Former
Marathon Shareholders as determined in accordance with the provisions hereof.

	 	(ii)	 	No Former Marathon Shareholder shall be entitled to receive any consideration with respect to
the Class A Shares other than the cash payment, if any, and certificates representing the
Stillwater Shares, if any, which they are entitled to receive in accordance herewith of this Plan
of Arrangement and, for greater certainty, no Former Marathon Shareholder will be entitled to
receive any interest, dividends, premium or other payment in connection therewith.
	 
	 	(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.

	 	(d)	 	Lost Certificates. In the event that any certificate which immediately prior to the
Effective Time represented one or more Marathon Shares which were exchanged for

	 	 	 	Stillwater Shares and Marathon Gold Shares in accordance with section 3 hereof shall have been
lost, stolen or destroyed, upon the making of an affidavit of that fact by the holder claiming such
certificate to be lost, stolen or destroyed, the Depositary shall
deliver in exchange for such lost,
stolen or destroyed certificate, certificates representing the Stillwater Shares and the Marathon
Gold Shares which such Marathon Shareholder is entitled to receive in accordance with section 3
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.
	 
	 	(e)	 	Dividends or other Distributions. No dividends or distributions declared or made after
the Effective Date with respect to Stillwater Shares with a record date after the Effective Date
will be payable or paid to the holder of any unsurrendered certificate or certificates which,
immediately prior to the Effective Date, represented outstanding Marathon Shares unless and until
the holder of such certificate shall have complied with the provisions of this section 5. 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

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. To the extent that
amounts are so withheld, such withheld amounts shall be treated for all purposes hereof as having been paid to the Marathon
Shareholder in respect of which such deduction and withholding was made, provided that such
withheld amounts are actually remitted to the appropriate taxing authority.

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.

5.

 

	 	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

6.

 

	 	 	 	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.

	4.	 	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

	 	(a)	 	Deposit. At or prior to the Effective Time:

	 	(i)	 	Marathon shall deposit with the Depositary, for the benefit of the Former Marathon
Shareholders, certificate(s) representing the Marathon Gold
Shares;

7.

 

	 	(ii)	 	AquireCo shall deposit with the Depositary, for the benefit of the Former
Marathon Shareholders, cash in an amount equal to the Maximum Cash; and
	 
	 	(iii)	 	Stillwater shall deposit with the Depositary, for the benefit of the Former Marathon
Shareholders, certificate(s) representing the Maximum Shares.

	 	(b)	 	Letter of Transmittal. The Depositary will forward to each Marathon Shareholder, at the
address of such Marathon Shareholder as it appears on the register for Marathon Shares, a Letter of
Transmittal and instructions for obtaining delivery of the certificates representing the Marathon
Gold Shares and the Stillwater Shares allotted and issued to such Marathon Shareholder pursuant to
the Arrangement.
	 
	 	(c)	 	Entitlement to Marathon Gold Certificates and Stillwater Certificates and cash.

	 	(i)	 	Stillwater, AcquireCo and Marathon shall cause the Depositary, as soon as
practicable following the later of the Effective Date and the date of deposit with the Depositary
of a duly completed Letter of Transmittal and the certificates
representing the Marathon Shares or other documentation as provided in the Letter of Transmittal,
to:

	 	A.	 	forward or cause to be forwarded by first class mail (postage prepaid) to the Former Marathon
Shareholders at the address specified in the Letter of Transmittal; or
	 
	 	B.	 	if requested by the Former Marathon Shareholders in the Letter of Transmittal, make available at
the Depositary for pick-up by the Former Marathon Shareholders; or
	 
	 	C.	 	if the Letter of Transmittal neither specifies an address nor contains a request as described in
(ii), forward or cause to be forwarded by first class mail (postage prepaid) to the Former Marathon
Shareholders at the address of such Former Marathon Shareholders as shown on the share register
maintained by Marathon as at the Effective Time,

	 	 	 	certificates representing the Marathon Gold Shares issuable to such Former Marathon Shareholders
and a cheque representing the cash payment, if any, payable to such Former Marathon Shareholders
and/or certificates representing the number of Stillwater Shares, if any, issuable to such Former
Marathon Shareholders as determined in accordance with the provisions hereof.
	 
	 	(ii)	 	No Former Marathon Shareholder shall be entitled to receive any consideration with respect to
the Class A Shares other than the cash payment, if any, and certificates representing the
Stillwater Shares, if any, which they are entitled to receive in accordance herewith of this Plan
of Arrangement and, for greater certainty, no Former Marathon Shareholder will be entitled to
receive any interest, dividends, premium or other payment in connection therewith.
	 
	 	(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

8.

 

	 	 	 	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.

	 	(d)	 	Lost Certificates. In the event that any certificate which immediately prior to the
Effective Time represented one or more Marathon Shares which were exchanged for Stillwater Shares
and Marathon Gold Shares in accordance with section 3 hereof shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the holder claiming such certificate to
be lost, stolen or destroyed, the Depositary shall deliver in exchange for such lost, stolen or
destroyed certificate, certificates representing the Stillwater Shares and the Marathon Gold Shares
which such Marathon Shareholder is entitled to receive in accordance with section 3 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.
	 
	 	(e)	 	Dividends or other Distributions. No dividends or distributions declared or made after
the Effective Date with respect to Stillwater Shares with a record date after the Effective Date
will be payable or paid to the holder of any unsurrendered certificate or certificates which,
immediately prior to the Effective Date, represented outstanding Marathon Shares unless and until
the holder of such certificate shall have complied with the provisions of this section 5. 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

9.

 

	 	 	 	or foreign tax law, in each case, as amended. To the extent that amounts are so withheld,
such withheld amounts shall be treated for all purposes hereof as having been paid to the Marathon
Shareholder in respect of which such deduction and withholding was made, provided that such
withheld amounts are actually remitted to the appropriate taxing authority.

	6.	 	AMENDMENT

	 	(a)	 	Amendment.

	 	(i)	 	Stillwater, AcquireCo, Marathon and Marathon Gold reserve the right to amend, modify and/or
supplement this Plan of Arrangement at any time and from time to time prior to the Effective Date,
provided that any amendment, modification or supplement must be approved by Stillwater and Marathon
in a written document which is filed with the Court and, if made following the Marathon Meeting,
then approved by the Court, and communicated to the Marathon Shareholders in the manner required by
the Court (if so required).
	 
	 	(ii)	 	Any amendment, modification or supplement to this Plan of Arrangement, if agreed to by
Marathon and Stillwater, may be made at any time prior to or at the Marathon Meeting, with or
without any other prior notice or communication and, if so proposed and accepted by Persons voting
at the Marathon Meeting (other than as may be required under the Interim Order) shall become part
of this Plan of Arrangement for all purposes.
	 
	 	(iii)	 	Any amendment, modification or supplement to this Plan of Arrangement that is approved or
directed by the Court following the Marathon Meeting will be effective only if it is consented to
by Marathon and Stillwater and, if required by the Court, by the Marathon Shareholders.
	 
	 	(iv)	 	Notwithstanding the foregoing provisions of this section 6, no amendment, modification or
supplement of this Plan of Arrangement may be made prior to the Effective Time except in accordance
with the terms of the Arrangement Agreement.
