For greater certainty, any and all Liabilities that arise after
the Adjustment Date that are not set forth in the preceding clauses (a) through
(m) shall not be Excluded Liabilities, and shall be Liabilities of McEwen after

and satisfy in due course all Excluded Liabilities that Primero and its
affiliates are obligated to pay and satisfy.

|2.5 | Purchase Price
|--- | --------------

The purchase price payable by McEwen to Primero for the
Purchased Assets shall be fully paid and satisfied by the payment by McEwen of
an amount in cash equal to $35 million less the amount of the Primero Cash
Collateral (the "Purchase Price"), subject to adjustment in accordance
with Section 2.9, and the assumption of the Assumed
Liabilities, which Purchase Price shall be paid on the Closing Date by wire
transfer in immediately available United States funds, in accordance with wire
payment instructions to be provided by Primero to McEwen at least five (5)
Business Days prior to the Closing Date.

|2.6 | Allocation of Purchase
Price
|--- | ----------------------------

McEwen shall prepare and deliver to Primero, on or before the
day that is ten (10) Business Days prior to the Adjustment Date, a draft
statement of the Purchase Price allocation, and McEwen and Primero shall work in
good faith to finally settle such allocation of the Purchase Price (including
the amount of the Assumed Liabilities) at least five (5) Business Days prior to
the Adjustment Date. The allocation of the Purchase Price (including the Assumed
Liabilities) shall be final and binding upon the Parties for all purposes,
including the filing of all Tax or other returns and the preparation of all
financial statements and other documents and records, unless changes to such
allocation are required by the Canada Revenue Agency.

|2.7 | Assignment of Rights to the Purchased
  Assets
|--- | ----------------------------------------------

Upon receipt by Primero of the Purchase Price, all right, title
and interest in and to the Purchased Assets shall, as between the Parties, be
deemed to be transferred to, and held by, or on behalf of, McEwen
notwithstanding that further actions may be taken by the Parties to effectively
transfer title to McEwen after the Closing Time.

|4.5 | Access to Information and Access for Due
      Diligence
|--- | --------------------------------------------------------

From the date hereof, unless this Agreement is terminated in
accordance with its terms, subject to Law, Primero shall, and shall cause its

the business, operations, assets, properties and related rights comprising and
relating solely to the Purchased Assets, afford McEwen and the officers,
employees, agents and representatives of McEwen or any of its affiliates such
access as McEwen may reasonably request, without disrupting the business and
operations of Primero, during regular business hours of Primero, including for
the purpose of confirmatory due diligence, Transition Services Agreement
development, environmental site assessments, environmental compliance audits and
health and safety audits, facilitating post-closing business planning and
indemnification purposes, to the officers, employees, agents, properties, Books
and Records and Contracts of Primero, and shall make available to McEwen all
data and information as McEwen may reasonably request with respect thereto.

make any other public statement or disclosure with respect to this Agreement or
the Transaction without the prior consent of the other Party (which consent
shall not be unreasonably withheld or delayed), and Primero must not make any
filing with any Governmental Entity with respect to this Agreement or the
Transaction without the prior written consent of McEwen (which consent shall not
be unreasonably withheld or delayed); provided that any Party that, in the
opinion of its outside legal counsel, is required to make disclosure by Law
shall use its commercially reasonable efforts to give the other Party prior oral
or written notice and a reasonable opportunity to review or comment on the
disclosure, and if such prior notice is not possible, shall give such notice
immediately following the making of such disclosure. The Party making such
disclosure shall give reasonable consideration to any comments made by the other
Party or its legal counsel.

      provided the Required Consent and Approval to the replacement of the
      Primero Financial Assurance with the McEwen Financial Assurance at the

|--- | -----------

| | (a) | The Parties agree and acknowledge that the acquisition of
      the Purchased Assets hereunder involves the acquisition by McEwen of all
      or substantially all of the Canadian resource properties of Primero.
      McEwen and Primero covenant and agree to execute and file a joint election
      in the prescribed form contemplated under paragraph 66.7(7)(e) of the Tax
      Act, within the time limits prescribed by the Tax Act, in respect of the
      transfer of the Purchased Assets in order to have the "successor
      corporation" rules in the Tax Act apply in a manner that transfers from
      Primero to McEwen the maximum amount of Transferred Tax Pools allowable
      for such purposes. Primero shall prepare and execute such election and
      provide a copy of such election for McEwen's review at least 15 Business
      Days prior to the filing deadline. Primero shall accept any reasonable
      comments from McEwen in respect of such election prior to
filing.

| | (b) | If McEwen assigns its rights and obligations under this
      Agreement to a direct or indirect subsidiary (the "Assignee
      Purchaser") pursuant to Section 10.12, Primero
      represents that it is, and McEwen represents (on its own behalf and on
      behalf of the Assignee Purchaser, if any) that the Assignee Purchaser will
      be duly registered under subdivision (d) of Division V of Part IX of the
      Excise Tax Act(Canada) and shall provide its registration number
      to the other Party promptly upon request by such other Party. Primero and
      McEwen (on its own behalf and on behalf of any Assignee Purchaser)
      acknowledge and agree that Primero is selling, and McEwen or the Assignee
      Purchaser, as applicable, is acquiring, all or substantially all of the
      assets used in the business currently being conducted by Primero with
      respect to the Purchased Assets and, if McEwen assigns its rights and
      obligations under this Agreement to an Assignee Purchaser pursuant to
      Section 10.12, Primero and McEwen (on behalf of the
      Assignee Purchaser) each agree to jointly prepare and execute an election
      pursuant to section 167 of the Excise Tax Act(Canada). McEwen
      represents (on its own behalf and on behalf of the Assignee Purchaser)
      that it shall file such election in prescribed form and within the time
      limits contained in the Excise Tax Act(Canada) with the
      appropriate Governmental Entity. Any goods and services tax, harmonized
      sales tax and/or any other sales or similar tax incurred in connection
      with the Transaction, including, for greater certainty, where an election
      pursuant to section 167 of the Excise Tax Act(Canada) is not or
      cannot be validly made in respect of the Purchased Assets, shall be borne
      by McEwen or the Assignee Purchaser, as the case may be. McEwen shall
      indemnify Primero from any and all claims, liabilities, actions,
      proceedings, demands, losses, costs, penalties, goods and services taxes
      payable, fines, damages, interest and expenses suffered by or sustained by
      Primero pertaining to such election pursuant to section 167 of the
      Excise Tax Act(Canada), including in the event that such election
      is not accepted by the Canada Revenue Agency. For greater certainty, the
      Parties agree that, if McEwen assigns its rights and obligations under
      this Agreement to an Assignee Purchaser, Primero will not charge or
      collect any amount from the Assignee Purchaser on Closing on account of
      goods and services tax or harmonized sales tax on the basis that the

| | (c) | Within five (5) days after receipt of the Employee list
      delivered pursuant to Section 4.9(b), McEwen shall
      offer employment to each Employee (each, a "Prospective Employee")
      and shall make each such offer of employment, effective as of the Closing
      Time, to each Prospective Employee in accordance with Section 4.9(d) .
      McEwen will provide notice to Primero on the Closing Date of the names of
      those Prospective Employees who accept employment with McEwen (such
      Prospective Employees, together with all Inactive Employees, who commence
      employment with McEwen are collectively referred to herein as the
      "Transferred Employees"). Notwithstanding the foregoing, if any
      Prospective Employee to whom McEwen is required to make an offer of
      employment pursuant to this Section 4.9(c) is on an
      approved leave of absence from work with Primero at the time offers of
      employment by McEwen are to be made (each, an "Inactive Employee"),
      McEwen shall offer employment to such Inactive Employee on the earliest
      practicable date following the return of such Inactive Employee to work
      with Primero and otherwise on terms and conditions consistent with this
      Section 4.9(c) and Section 4.9(d), provided that
      such Inactive Employee returns to active employment within eighteen (18)
      months following the Closing Date or such later time as required by
      applicable Law. Primero shall promptly notify McEwen of the occurrence and
      end of any such leave of absence. Any Inactive Employee who accepts the
      offer of employment by McEwen upon the end of any leave of absence shall
      be a Transferred Employee, and all references in this Agreement to: (i)
      the Closing Date shall be deemed to be references to the date on which
      such individual becomes a Transferred Employee; and (ii) the Closing Time
      shall be deemed to be references to 12:01 a.m. local time on the date such
      individual becomes a Transferred Employee. For greater certainty, McEwen
      shall not be liable for any Employee Obligations paid by Primero to an
      Inactive Employee prior to the date upon which the Inactive Employee
      becomes a Transferred Employee.

hours of receipt of a proposal, inquiry or other written communication relating
in any way to a Competing Transaction, of the terms and conditions thereof, and
the identity of the Person or Persons making such proposal, inquiry or other
written communication. For greater certainty, any receipt by Primero of a
proposal in respect of a Competing Transaction shall not affect McEwens rights

| | (a) | Third Party Claims.If any Indemnified Party
      receives notice of the assertion or commencement of any Action made or
      brought by any Person who is not a party to this Agreement or an affiliate
      of a Party or a Representative of the foregoing (a "Third Party
      Claim") against such Indemnified Party with respect to which the
      Indemnifying Party is obligated to provide indemnification under this
      Agreement, the Indemnified Party shall give the Indemnifying Party prompt
      written notice thereof, but in any event not later than ten (10) calendar
      days after receipt of such notice of such Third Party Claim. The failure
      to give such prompt written notice shall not, however, relieve the
      Indemnifying Party of its indemnification obligations, except and only to
      the extent that the Indemnifying Party forfeits rights or defenses or is
      otherwise materially prejudiced by reason of such failure. Such notice by
      the Indemnified Party shall describe the Third Party Claim in reasonable
      detail, shall include copies of all material written evidence thereof
      (including any statement of claim or demand notice) and shall indicate the
      estimated amount, if reasonably practicable, of the Losses that have been
      or may be sustained by the Indemnified Party. The Indemnifying Party shall
      have the right to participate in, or by giving written notice to the
      Indemnified Party, to assume the defense of, any Third Party Claim at the
      Indemnifying Party's expense and by the Indemnifying Party's own legal
      counsel, and the Indemnified Party shall cooperate in good faith in such
      defense; provided, that the Indemnifying Party shall not have the right to
      defend or direct the defense of any such Third Party Claim that: (i) is
      asserted directly by or on behalf of a Person that is a supplier or
      customer relating to the Purchased Assets (if the Indemnifying Party is
      Primero); or (ii) seeks an injunction or other equitable relief against
      the Indemnified Party. In the event that the Indemnifying Party assumes
      the defense of any Third Party Claim, subject to Section 9.5(b), it shall have the right to take such action as
      it deems necessary to avoid, dispute, defend, appeal or make counterclaims
      pertaining to any such Third Party Claim in the name and on behalf of the
      Indemnified Party. The Indemnified Party shall have the right to
      participate in the defense of any Third Party Claim with legal counsel
      selected by it, subject to the Indemnifying Party's right to control the
      defense thereof. The fees and disbursements of such legal counsel shall be
      at the expense of the Indemnified Party; provided that, if in the
      reasonable opinion of legal counsel to the Indemnified Party, (A) there
      are legal defenses available to an Indemnified Party that are different
      from or additional to those available to the Indemnifying Party, or (B)
      there exists a conflict of interest between the Indemnifying Party and the
      Indemnified Party that cannot be waived, the Indemnifying Party shall be
      liable for the reasonable fees and expenses of legal counsel to the
      Indemnified Party in each jurisdiction in which the Indemnified Party
      determines legal counsel is required. If the Indemnifying Party elects not
      to compromise or defend such Third Party Claim, fails to promptly notify
      the Indemnified Party in writing of its election to defend as provided in
      this Agreement, or fails to diligently prosecute the defense of such Third
      Party Claim, the Indemnified Party may, subject to Section 9.5(b), pay, compromise (acting reasonably) or defend
      such Third Party Claim and seek indemnification for any and all Losses
      based upon, arising from or relating to such Third Party Claim. Primero
      and McEwen shall cooperate with each other in all reasonable respects in
      connection with the defense of any Third Party Claim, including making
      available records relating to such Third Party Claim and making available,
      without expense (other than reimbursement of actual out-of-pocket
      expenses) to the defending party, such then existing management employees
      of the non-defending party as may be reasonably necessary for the
      preparation of the defense of such Third Party Claim.

| | (b) | Settlement of Third Party Claims.Notwithstanding
      any other provision of this Agreement, the Indemnifying Party shall not
      enter into a settlement of any Third Party Claim without the prior written
      consent of the Indemnified Party, except as provided in this Section 9.5(b). If a firm offer is made to settle a Third
      Party Claim without leading to liability or the creation of a financial or other
      obligation on the part of the Indemnified Party and provides, in customary
      form, for the unconditional release of each Indemnified Party from all
      liabilities and obligations in connection with such Third Party Claim and
      the Indemnifying Party desires to accept and agree to such offer, the
      Indemnifying Party shall give written notice to that effect to the
      Indemnified Party. If the Indemnified Party fails to consent to such firm
      offer within ten (10) days after its receipt of such notice, the
      Indemnified Party may assume carriage of such matter, and continue to
      contest or defend such Third Party Claim and in such event, the maximum
      liability of the Indemnifying Party as to such Third Party Claim shall not
      exceed the amount of such settlement offer. If the Indemnified Party fails
      to consent to such firm offer and also fails to assume defense of such
      Third Party Claim, the Indemnifying Party may settle the Third Party Claim
      upon the terms set forth in such firm offer to settle such Third Party
      Claim. If the Indemnified Party has assumed the defense of the Third Party
      Claim pursuant to Section 9.5(a), it shall not
      agree to any settlement without the written consent of the Indemnifying
      Party (which consent shall not be unreasonably withheld or
  delayed).

| | (c) | Direct Claims.Any Action by an Indemnified Party
      on account of Losses that do not result from a Third Party Claim (a
      "Direct Claim") shall be asserted by the Indemnified Party giving
      the Indemnifying Party prompt written notice thereof, but in any event not
      later than ten (10) days after the Indemnified Party becomes aware of such
      Direct Claim. The failure to give such prompt written notice shall not,
      however, relieve the Indemnifying Party of its indemnification
      obligations, except and only to the extent that the Indemnifying Party
      forfeits rights or defenses or is otherwise materially prejudiced by
      reason of such failure. Such notice by the Indemnified Party shall
      describe the Direct Claim in reasonable detail, shall include copies of
      all material written evidence thereof (including any statement of claim or
      demand notice) and shall indicate the estimated amount, if reasonably
      practicable, of the Losses that have been or may be sustained by the
      Indemnified Party. The Indemnifying Party shall have 30 days after its
      receipt of such notice to respond in writing to such Direct Claim. The
      Indemnified Party shall allow the Indemnifying Party and its legal counsel
      to investigate the matter or circumstance alleged to give rise to the
      Direct Claim, and whether and to what extent any amount is payable in
      respect of the Direct Claim and the Indemnified Party shall assist the
      Indemnifying Party's investigation by giving such information and
      assistance (including access to the Indemnified Party's premises and
      personnel and the right to examine and copy any accounts, documents or
      records) as the Indemnifying Party or its legal counsel may reasonably
      request. If the Indemnifying Party does not so respond within such 30 day
      period, the Indemnifying Party shall be deemed to have rejected such
      Direct Claim, in which case the Indemnified Party shall be free to pursue
      such remedies as may be available to the Indemnified Party on the terms
      and subject to the provisions of this
Agreement.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|9.6 | Payments
|--- | --------

Once any Losses are agreed to by the Indemnifying Party or
finally adjudicated to be payable pursuant to this Article
9, the Indemnifying Party shall satisfy its obligations within fifteen (15)
days of such final, non-appealable adjudication by wire transfer of immediately
available funds. The Parties agree that should an Indemnifying Party not make
full payment of any such obligations within such fifteen (15) day period, any
amount payable shall accrue interest from and including the date of agreement of
the Indemnifying Party or final, non-appealable adjudication to, but excluding,
the date such payment has been made in full, at a rate per annum equal to the
Prime Rate plus 5%. Such interest shall be calculated daily on the basis of a
365 day year and the actual number of days elapsed.

-36-

|9.7 | Tax Treatment of Indemnification
  Payments
|--- | -------------------------------------------

All indemnification payments made under this Agreement shall be
treated by the Parties as an adjustment to the Purchase Price for Tax purposes,
unless otherwise required by Law, and shall be allocated as among the Purchased
Assets by the Parties, each acting reasonably.

|9.8 | One Recovery
|--- | ------------

An Indemnified Party is not entitled to double recovery for any
Losses even though they may have resulted from the breach, inaccuracy or failure
to perform of more than one of the representations, warranties, covenants and
obligations of the Indemnifying Party in this Agreement. No Party has any
liability or obligation with respect to any Losses subject to indemnification
under Section 9.2 or Section 9.3
to the extent that such Losses were reflected as an adjustment to the Purchase
Price in Section 2.9.

|9.9 | Duty to Mitigate
|--- | ----------------

Nothing in this Agreement in any way restricts or limits the
general obligation at Law of an Indemnified Party to mitigate any Losses which
it may suffer or incur by reason of the breach, inaccuracy or failure to perform
of any representation, warranty, covenant or obligation of the Indemnifying
Party under this Agreement. If any Losses can be reduced by any recovery,
settlement, payment or otherwise under or pursuant to any insurance coverage, or
pursuant to any claim, recovery, settlement or payment by or against any other
Person, the Indemnified Party shall take all appropriate steps to enforce such
recovery, settlement or payment and the amount of any Losses of the Indemnified
Party will be reduced by the amount of insurance proceeds actually recovered by
the Indemnified Party.

|9.10 | Effect of Investigation
|---- | -----------------------

A Party shall have no obligation or liability for
indemnification under Section 9.2, Section 9.3 or otherwise with respect to any breach or inaccuracy of
any representation or warranty in this Agreement or any failure to perform or
fulfill any covenants or obligations, if the Party making the claim had
knowledge of the breach, inaccuracy or failure to perform on or prior to the
Closing.

|9.11 | Exclusive Remedies
|---- | ------------------

Subject to Section 10.3, the Parties
acknowledge and agree that their sole and exclusive remedy with respect to any
and all claims (other than claims arising from fraud, criminal activity or
willful misconduct on the part of a Party in connection with the Transaction)
for any breach of any representation, warranty, covenant, agreement or
obligation set forth herein or otherwise relating to the subject matter of this
Agreement, shall be pursuant to the indemnification provisions set forth in this
Article 9. In furtherance of the foregoing, each Party
hereby waives, to the fullest extent permitted under Law, any and all rights,
claims and causes of action for any breach of any representation, warranty,
covenant, agreement or obligation set forth herein or otherwise relating to the
subject matter of this Agreement it may have against the other Party and its
affiliates and each of their respective Representatives arising under or based
upon any Law, except pursuant to the indemnification provisions set forth in
this Article 9. Nothing in this Section 9.11 shall limit
any Person's right to seek and obtain any equitable relief to which any Person
shall be entitled or to seek any remedy on account of any party's fraudulent,
criminal or intentional misconduct.

|9.12 | Trusts
|---- | ------

It is the intention of: (i) Primero to constitute McEwen as a
trustee for McEwen Indemnitees that are not parties to this Agreement of the
covenants of Primero contained in this Article 9 and
McEwen agrees to accept such trust and to hold and enforce such covenants on
behalf of each such McEwen Indemnitee; and (ii) McEwen to constitute Primero as a trustee for the Primero
Indemnitees that are not parties to this Agreement of the covenants of McEwen
contained in this Article 9 and Primero agrees to accept
such trust and to hold and enforce such covenants on behalf of each such Primero
Indemnitee.

ARTICLE 10 GENERAL PROVISIONS

|10.1 | Amendments
|---- | ----------

This Agreement may only be amended by mutual written agreement
of the Parties.

|10.2 | Expenses
|---- | --------

Primero will be responsible for the costs relating to the Title
Insurance Policy and the Title Opinion. Subject to the foregoing or as otherwise
expressly agreed between the Parties, all out-of-pocket third party transaction
expenses incurred in connection with this Agreement and the Transaction,
including all costs, expenses and fees of Primero and McEwen incurred prior to
or after the Closing Date in connection with, or incidental to, the Transaction,
shall be paid by the Party incurring such expenses, whether or not the
Transaction is completed, except as expressly provided in this Agreement.

|10.3 | Injunctive Relief and
Remedies
|---- | ------------------------------

The Parties agree that irreparable harm would occur for which
money damages would not be an adequate remedy at Law in the event that any of
the provisions of this Agreement were not performed by Primero or McEwen in
accordance with their specific terms or were otherwise breached. It is
accordingly agreed that each Party shall be entitled to injunctive and other
equitable relief to prevent breaches or threatened breaches of this Agreement by
the other Party, and to enforce compliance with the terms of this Agreement by
the other Party without any requirement for the securing or posting of any bond
in connection with the obtaining of any such injunctive or other equitable
relief, this being in addition to any other remedy to which a Party may be
entitled at Law or in equity.

|10.4 | Privacy Matters
|---- | ---------------

| | (a) | The Disclosing Party acknowledges and confirms that the
      disclosure of Transaction Personal Information is necessary for the
      purposes of determining if the Parties will proceed with the Transaction,
      and that the disclosure of Transaction Personal Information relates solely
      to the carrying on of the business and the review of the Purchased Assets
      and the Closing.

      Personal Information relates and all additional documented purposes where

| | (g) | In this Agreement, "Transaction Personal
      Information" means personal information (namely, information about an
      identifiable individual other than their business contact information when
      used or disclosed for the purpose of contacting such individual as a
      representative of an organization and for no other purpose) to be
      disclosed or conveyed to one Party or any of its Representatives (a
      "Recipient") by or on behalf of another Party (a "Disclosing
      Party") as a result of or in conjunction with the Transaction, and
      includes all such personal information disclosed to the Recipient prior to
      the execution of this Agreement.

|10.5 | Further Assurances
|---- | ------------------

From time to time after the Closing Date, a Party shall, at the
request of the other Party, execute and deliver such additional conveyances,
transfers and other assurances as may be reasonably required to effectively
complete the Transaction and to carry out the intent of this Agreement. Without
limiting the generality of the foregoing, to the extent that any Purchased Asset
is not transferred to McEwen, upon the written request of McEwen, Primero shall
use its best efforts to transfer, or to cause the transfer of, such asset to
McEwen or take other appropriate steps to allow McEwen to enjoy the benefit of
such Purchased Asset.

Any notice or other communication is deemed to be given and
received: (i) if sent by personal delivery or same day courier, on the date of
delivery if it is a Business Day and the delivery was made prior to 4:00 p.m.
and otherwise on the next Business Day; (ii) if sent by overnight courier, on
the next Business Day; or (iii) if sent by electronic mail, on the next Business
Day. Sending a copy of a notice or other communication to a Party's legal
counsel as contemplated above is for information purposes only and does not
constitute delivery of the notice or other communication to that Party. The
failure to send a copy of a notice or other communication to legal counsel does
not invalidate delivery of that notice or other communication to a Party.

Person, other than the Parties, shall be entitled to rely on the provisions of
this Agreement in any action, suit, proceeding, hearing or other forum.

|10.9 | Brokerage and Finder's
Fees
|---- | ---------------------------

It is understood and agreed that, other than Scotia Capital
Inc., no broker, agent or other intermediary acted for either Primero or McEwen
in connection with the sale or purchase of the Purchased Assets and: (i) Primero
agrees to indemnify McEwen and hold it harmless in respect of any claim for
brokerage or other commissions relating to this Agreement or the Transaction
which is caused by any action of Primero or any of its affiliates; and (ii)
McEwen agrees to indemnify Primero and hold it harmless in respect of any claim
for brokerage or other commissions relating to this Agreement or to the
Transaction which is caused by any action of McEwen or any of its affiliates.

|10.10 | Waiver
|----- | ------

No waiver of any of the provisions of this Agreement will
constitute a waiver of any other provision (whether or not similar). No waiver
will be binding unless executed in writing by the Party to be bound by the
waiver. A Party's failure or delay in exercising any right under this Agreement
will not operate as a waiver of that right. A single or partial exercise of any
right will not preclude a Party from any other or further exercise of that right
or the exercise of any other right.

|10.11 | Entire Agreement
|----- | ----------------

This Agreement constitutes the entire agreement between the
Parties with respect to the Transaction and supersedes all prior agreements,
understandings, negotiations and discussions, whether oral or written, of the
Parties. There are no representations, warranties, covenants, conditions or
other agreements, express or implied, collateral, statutory or otherwise,
between the Parties in connection with the subject matter of this Agreement,
except as specifically set forth in this Agreement. The Parties have not relied
and are not relying on any other information, discussion or understanding in
entering into and completing the Transaction.

|10.12 | Successors and Assigns
|----- | ----------------------

| | (a) | This Agreement becomes effective only when executed by
      Primero and McEwen. After that time, it will be binding upon and enure to
      the benefit of Primero and McEwen and their respective successors and
      permitted assigns.

      Agreement are assignable or transferable by any Party without the prior
      written consent of the other Party.

| | (c) | Notwithstanding Section 10.12(b),
      McEwen may assign all or any part of its rights and obligations under this
      Agreement to a wholly-owned direct or indirect subsidiary of McEwen
      without the consent of Primero, provided that McEwen shall provide Primero

will be severed from this Agreement and the remaining provisions shall remain in
full force and effect. Upon such determination that any term or other provision

REPRESENTATIONS AND WARRANTIES OF PRIMERO

Except as set forth in the correspondingly numbered paragraph
of the Disclosure Letter, Primero hereby makes the following representations and
warranties to McEwen, and acknowledges and agrees that McEwen is relying upon
such representations and warranties in connection with the entering into of this
Agreement. The Parties agree that inclusion of an item in any schedule of the
Disclosure Letter or in any Schedule attached hereto is deemed to be disclosure
for all purposes for which disclosure is required under this Agreement,
including in the following representations and warranties.

      Business Corporations Act(British Columbia) and has full corporate
      power and authority to own, lease and operate its assets and conduct its

      qualified to carry on business and is in good standing in each
      jurisdiction in which the character of its properties or the nature of its

      be so qualified will not, individually or in the aggregate, have a Primero
      Material Adverse Effect. True and complete copies of the constating
      documents of Primero have been delivered or made available to McEwen, and
      Primero has not taken any action to amend or supersede such constating
      documents.

      not violate, conflict with or result in a breach of any provision of the
      constating documents of Primero, and except for Required Consents and
      Approvals or as would not, individually or in the aggregate, have or
      reasonably be expected to have a Primero Material Adverse Effect will not:
      (i) violate, conflict with or result in a breach of (A) any agreement,
      contract, indenture, deed of trust, mortgage, bond, instrument,
      Authorization, licence or permit to which Primero is a party, or by which

      in control or influence provisions or any restriction or limitation under
      any such agreement, Contract, indenture, Authorization, deed of trust,
      mortgage, bond, instrument, licence or permit, or result in the imposition
      of any encumbrance, charge or lien upon any of the Purchased Assets. Other
      than Required Consents and Approvals disclosed in Schedule H, no
      Authorization, consent or approval of, or filing with, any Governmental
      Entity or other authority is necessary on the part of Primero for the
      completion by it of its obligations under this Agreement or for the
      completion of the Transaction that would cause or result in any loss of
      any rights or assets or any interest therein held by Primero, except for such Authorizations,
      consents, approvals and filings as to which the failure to obtain or make
      would not, individually or in the aggregate, prevent or materially delay
  completion of the Transaction.

      regulations which restrict or prohibit in any material respect the use of
      any Purchased Asset for the purposes for which it is presently being used,
      other than the Permitted Encumbrances, and Primero has received no notice
      and is not aware of any proposed changes to any official plan or zoning
      by-laws which could materially and adversely affect or prohibit such
      uses.

      and practices, and in all material respects in accordance with all
      applicable Laws, including the requirements of NI 43- 101. There has been
      no material reduction in the aggregate amount of estimated mineral
      resources or mineral reserves in relation to the Purchased Assets, taken
      as a whole, from the most recent amounts disclosed in the Primero Public Documents,
  subject to Ordinary Course depletion due to mining activities.

      whether they are on an approved or statutory leave of absence and, if so,
      the reason for such absence and the expected date of return, if known; and
      (viii) whether they are subject to a written employment agreement. True
      and complete copies of all written employment agreements to which Primero
      and any Employee are parties or bound have been provided or made available
      to McEwen. Except for these written employment agreements, Primero is not
      a party to or bound by any oral or written contract or commitment for the

| | (h) | Primero is in compliance in all material respects with
      all terms and conditions of any written employment agreement or consulting
      agreement with any Employee or any consultant, as the case may be, to
      which Primero is a party or bound, and is in material compliance with all
      Laws respecting labour and employment, including minimum employment
      standards, pay equity, wages, hours of work, overtime, human rights,
      occupational health and safety and workers compensation with respect to
      the Employees. Except as disclosed in Schedule (12)(h) of the Disclosure Letter, Primero is not
      subject to any outstanding or, to Primero's knowledge, threatened
      grievance, complaint, investigation, order, claim, litigation or other
      labour-related or employment-related dispute or proceeding under such Laws
      relating to labour and employment, with respect to any Employee or
      independent contractor or consultant providing services relating to the
      Purchased Assets. No event has occurred that, with the notice or lapse of
      time or both, would constitute a material breach, violation or default of
      such terms and conditions of any written employment agreement or
      consulting agreement with any Employee or consultant to which Primero is a
      party or bound. Primero does not have any prior convictions or pending
      charges under the Occupational Health and Safety Act(Ontario) or
      any other applicable occupational health and safety
  legislation.

|(3) | No Conflict; Required Filings and Consent. The
      execution and delivery by McEwen of this Agreement and the performance of
      its covenants hereunder and the completion of the Transaction will not
      violate, conflict with or result in a breach of any provision of the
      constating documents of McEwen, and except as would not, individually or
      in the aggregate, have or reasonably be expected to have a Material
      Adverse Effect with respect to McEwen, will not violate, conflict with or
      result in a breach of: (i) any agreement, contract, indenture, deed of
      trust, mortgage, bond, instrument, Authorization, licence or permit to
      which McEwen is a party, or by which it is bound; or (ii) any Law to which
      McEwen is subject or by which it is bound. No Authorization, consent or
      approval of, or filing with, any Governmental Entity or other authority is
      necessary on the part of McEwen for the completion of its obligations in
      connection with the Transaction under this Agreement, except for such
      Authorizations, consents, approvals and filings as to which the failure to
      obtain or make would not, individually or in the aggregate, prevent or
      materially delay completion of the Transaction.

      arise after the date of this Agreement and which do not have a reasonable
      prospect of succeeding or, if successful, would not give rise to, nor
      reasonably be expected to give rise to, a McEwen Material Adverse Effect.
      McEwen is not subject to any outstanding order, writ, injunction or decree
      which has had or could reasonably be expected to have, a McEwen Material Adverse Effect or
  which would prevent or materially delay the Closing.
