The undersigned, CIBC World Markets Inc. (CIBC),

(UBS), BMO Nesbitt Burns Inc., Dahlman Rose & Company, LLC
(Dahlman), GMP Securities L.P., Credit Suisse Securities (Canada), Inc.

Inc. (the Silver Standard) and Pretium Resources Inc.
(Pretivm) propose to sell to the Underwriters an aggregate of
10,000,000 units (the Purchased Units), each Purchased Unit to consist
of a common share of Pretivm (a Purchased Share) owned by Silver
Standard and one-half of one common share purchase warrant (each whole common
share purchase warrant, a Purchased Warrant), each full Purchased
Warrant being exercisable to purchase one common share of Pretivm at a price of
$12.50 (the Warrant Exercise Price) at any time prior to the date that
is 12 months after Closing (the Expiry Date). The Warrants shall be
issued pursuant to, and the exercise thereof shall be governed by, the
provisions of a warrant indenture (the Warrant Indenture), to be
entered into between Pretivm and Computershare Trust Company of Canada, as
warrant agent (the Warrant Agent). Each Unit (as hereinafter defined)
shall be separated into one Common Share and one-half Warrant at the Closing
Time (as hereinafter defined).

Upon and subject to the terms and conditions set forth herein,
the Underwriters hereby severally, and not jointly, offer to purchase from
Silver Standard in the respective percentages set forth in section 18 hereof,
Silver Standard agrees to sell to the Underwriters on an underwritten basis, all
but not less than all of the Purchased Shares at a price of $9.60 per Purchased
Share and Pretivm agrees to sell to the Underwriters on an underwritten basis,
all but not less than all of the Purchased Warrants at a price of $0.40 per
one-half Purchased Warrant, representing an aggregate purchase price per Unit of
$10.00 (the Purchase Price) for gross proceeds of $100,000,000 payable
to Silver Standard as provided in section 11(a), provided that the Underwriters
may distribute the Units: (i) in each of the provinces and territories of
Canada, other than Québec, pursuant to the Final Prospectus (as hereinafter
defined); (ii) in the United States on a substituted purchaser (Substituted
Purchaser) basis, through the U.S. Placement Agent(s) (as defined below)
pursuant to the exemptions from registration requirements of the 1933 Act (as
defined below) in accordance with Schedule A attached and Rule 506 of
Regulation D in accordance with Schedule A attached hereto; and (iii) in
accordance with the local laws of such other jurisdictions as may be agreed by
Silver Standard, Pretivm and the Underwriters (together, the Offering).
The number of Units to be purchased by the Underwriters hereunder shall be
reduced as a result of any sales of Units to Substituted Purchasers.

By acceptance of this Agreement, Pretivm grants to the
Underwriters an unassignable right to purchase, severally and not jointly, up to
1,500,000 additional Units (the Additional Units), at a price per
Additional Unit equal to the Purchase Price, for the purposes of covering
over-allotments, if any, and for market stabilization purposes in connection
with the Offering. The Over-Allotment Option may be exercisable by the
Underwriters in respect of: (i) Additional Units at the Offering Price; or (ii)
additional common shares of Pretivm owned by Silver Standard (the Additional
Shares) at a price of $9.60 per Additional Share; or (iii) additional
Warrants (the Additional Warrants) at a price of $0.40 per one-half
Additional Warrant; or (iv) any combination of Additional Units and/or
Additional Shares and/or Additional Warrants, so long as the aggregate number of
Additional Shares and Additional Warrants which may be issued under the
Over-Allotment Option does not exceed 1,500,000 Additional Shares and 750,000
Additional Warrants. In the event that the Over-Allotment Option is exercised,
any Additional Units and/or Additional Shares and/or Additional Warrants issued
thereunder shall be deemed to form part of the Offering for the purposes hereof
and all of the terms and conditions relating to the Closing shall apply to the
Over-Allotment Closing (as defined herein). Silver Standard and Pretivm covenant
and agree to do all such acts and things as may be required or advisable in
order for such right to be exercisable in the manner described in the Prospectus
(defined below). If CIBC, Citi and UBS (collectively, the Lead
Underwriters), on behalf of the Underwriters, elect to exercise such right,
the Lead Underwriters shall notify Silver Standard and Pretivm in writing, which
notice (the Over-Allotment Notice) shall specify the number of
Additional Units and/or Additional Shares and/or Additional Warrants to be
purchased by the Underwriters and the date on which such Additional Units,
and/or Additional Shares and/or Additional Warrants are to be purchased, which
date may be the same as the Closing Date but not earlier than the Closing Date
and shall not be later than 30 days following the Closing Date. The Option
Closing Date shall not be earlier than three Business Days (as defined below)
nor later than five Business Days after the date of the Over-Allotment Notice.
If any Additional Units and/or Additional Shares and/or Additional Warrants are
purchased, each Underwriter agrees, severally and not jointly, to purchase that
number of Additional Units and/or Additional Shares and/or Additional Warrants
(subject to such adjustments to eliminate fractional shares and/or warrants as
the Lead Underwriters may determine) equal to the total number of Additional
Units, and/or Additional Shares and/or Additional Warrants to be purchased
multiplied by the percentage set out in section 18 of this Agreement opposite
the name of such Underwriter.

The Purchased Units and the Additional Units are hereinafter
collectively referred to as the Units. The Purchased Shares and the
Additional Shares are hereinafter collectively referred to as the

      the Final Prospectus (with the requisite procedures to be completed by
      such auditors within two Business Days of the date of the Final
      Prospectus), addressed to the Underwriters, the Directors, Pretivm and
      Silver Standard and its directors in form and substance satisfactory to
      the Underwriters, with respect to certain financial and accounting
      information relating to Pretivm in the Final Prospectus, which letters
      shall be in addition to the auditors reports contained in the Final
      Prospectus and any auditors comfort letters addressed to the Canadian
      Securities Regulators.

| | (b) | Prospectus Amendments
| | --- | ---------------------

In the event that Pretivm or Silver Standard is required by
Canadian Securities Laws to prepare and file a Prospectus Amendment, Pretivm and
Silver Standard shall prepare and deliver promptly to the Underwriters signed
and certified copies of such Prospectus Amendment in the English language. Any
Prospectus Amendments shall be in form and substance satisfactory to the
Underwriters and their counsel. Concurrently with the delivery of any Prospectus
Amendments, Pretivm shall deliver to the Underwriters, with respect to such
Prospectus Amendment, documents similar to those referred to in section 4(a).
Subject to their rights under section 13, the Underwriters agree to deliver a
copy of any Prospectus Amendment to each actual or prospective purchaser of
Units from the Underwriters.

In addition to the matters set forth above in this section 4
and in section 9, each of Pretivm and Silver Standard shall, in good faith,
discuss with the Underwriters any change, event or fact contemplated in those
sections that is of a nature that there may be reasonable doubt as to whether
notice should be given to the Underwriters under section 9 and shall consult
with the Underwriters with respect to the form and content of any Prospectus
Amendment, it being understood and agreed that no such Prospectus Amendment
shall be filed with any Canadian Securities Regulator prior to being reviewed by
the Underwriters and their counsel.

| | (c) | Commercial Copies
| | --- | -----------------

Pretivm shall cause commercial copies of the Final Prospectus
in the English language, the U.S. Placement Memorandum for Institutions and the
U.S. Placement Memorandum for Non-Institutions to be delivered to the
Underwriters without charge, in such quantities and in such cities as the
Underwriters may reasonably request to the printer of such documents. Such
delivery of the Final Prospectus shall be effected as soon as possible after
filing thereof with, and receipt of the Final Receipt therefor from, the Canadian
Securities Regulators but, in any event, on or before 12:00 p.m. (Eastern time)
on the Business Day after the date of the Final Receipt. Such deliveries shall
constitute the consent of Pretivm to the Underwriters use of the Final
Prospectus, the U.S. Placement Memorandum for Institutions and the U.S.
Placement Memorandum for Non-Institutions for the distribution of: (i) the Units
in the Qualifying Provinces; and (ii) the Purchased Units in the Qualifying
States, in compliance with the provisions of this Agreement, Canadian Securities
Laws and U.S. Securities Laws. Pretivm shall similarly cause to be delivered
commercial copies of any Prospectus Amendments. The commercial copies of the
Final Prospectus and any Prospectus Amendment shall be identical in content to
the electronically transmitted versions thereof filed with Canadian Securities
Regulators pursuant to the System for Electronic Document Analysis and
Retrieval.

| | (d) | Press Releases

During the period commencing on the date hereof and until
completion of the distribution of the Units, each of Pretivm and Silver Standard
will (i) promptly provide the Underwriters with drafts of any press releases of
Pretivm or Silver Standard, as the case may be, for review by the Underwriters
and their counsel prior to issuance (provided that, in the case of Silver
Standard, such obligation shall only apply to press releases relating to the
Offering and the Delivery Agreement), and (ii) if requested by the Lead
Underwriters, subject to applicable laws, include a reference to the
Underwriters and their role in the Offering in any press releases of Pretivm or
Silver Standard with respect to the Offering.

      property rights. The Mining Claims by Pretivm or Pretivm Exploration cover
      the properties required by Pretivm for the purposes described in the
      Prospectus and no other property rights are necessary for the conduct of
      Pretivms business as described in the Prospectus. No dispute between
      Pretivm or Pretivm Exploration and any local, native or indigenous group
      exists or to the knowledge of Pretivm is threatened or imminent with
      respect to the Snowfield Project, the Brucejack Project or Pretivms
      exploration activities that could reasonably be expected to have a
      Material Adverse Effect.

      activity involving any kind of hazardous, toxic or other wastes,
      pollutants, contaminants, petroleum products or other hazardous or toxic
      substances, chemicals or materials (Hazardous Substances) by, due
      to, on behalf of, or caused by Pretivm or Pretivm Exploration (or, to
      Pretivms knowledge, any other entity for whose acts or omissions Pretivm
      is or may be liable) upon any property now or previously owned, operated,
      used or leased by Pretivm or Pretivm Exploration, or upon any other
      property, which would be a violation of or give rise to any liability
      under any applicable law, rule, regulation, order, judgment, decree or
      permit, common law provision or other legally binding standard relating to
      pollution or protection of human health and the
  environment (Environmental Law), except for violations and
      liabilities which, individually or in the aggregate, could not reasonably
      be expected to have a Material Adverse Effect. There has been no disposal,
      discharge, emission contamination or other release of any kind at, onto or
      from any such property or into the environment surrounding any such
      property of any Hazardous Substances with respect to which Pretivm has
      knowledge, except as could not, individually or in the aggregate,
      reasonably be expected to have a Material Adverse Effect. There is no
      pending or, to the best of Pretivms knowledge, threatened administrative,
      regulatory or judicial action, claim or notice of noncompliance or
      violation, investigation or proceedings relating to any Environmental Law
      against Pretivm or Pretivm Exploration, except as could not, individually
      or in the aggregate, reasonably be expected to have a Material Adverse
      Effect. No property of Pretivm or Pretivm Exploration is subject to any
      Lien under any Environmental Law, other than Permitted Encumbrances.
      Neither Pretivm nor Pretivm Exploration is subject to any order, decree,
      agreement or other individualized legal requirement related to any
      Environmental Law, which, in any case (individually or in the aggregate),
  could reasonably be expected to have a Material Adverse Effect.

| | (iii) | any change in any material fact (which for the purposes
      of this Agreement shall be deemed to include the disclosure of any
      previously undisclosed material fact) contained in the Final Prospectus or
      any Prospectus Amendment, which fact or change is, or may be, of such a
      nature as to render any statement in the Final Prospectus or any
      Prospectus Amendment misleading or untrue in any material respect or which
      would result in a misrepresentation in the Final Prospectus or any
      Prospectus Amendment or which would result in the Final Prospectus or any
      Prospectus Amendment not complying (to the extent that such compliance is
      required) with Canadian Securities Laws, in each case, as at any time up
      to and including the later of the Closing Date, the Option Closing Date
      and the date of completion of the distribution of the
  Units,

provided, however, in the case of
Silver Standard, the obligations to notify the Underwriters in accordance with
Subsections 9(a)(i),(ii) and (iii) above, shall only apply to the extent that
any such changes, facts or changes in material facts relate to the Silver
Standard Matters,

Pretivm shall promptly, and in any event within any applicable
time limitation, comply, to the satisfaction of the Underwriters, acting
reasonably, with all applicable filings and other requirements under the
Canadian Securities Laws as a result of such fact or change; provided that
Pretivm shall not file any Prospectus Amendment or other document without first
obtaining from the Underwriters their approval, after consultation with the
Underwriters with respect to the form and content thereof, which approval will
not be unreasonably withheld or delayed. Pretivm shall in good faith discuss
with the Underwriters any fact or change in circumstances (actual, anticipated,
contemplated or threatened, financial or otherwise) which is of such a nature
that there is reasonable doubt whether written notice need be given under this
section 9(a).

| | (b) | Change in Canadian Securities
  Laws
| | --- | ------------------------------------

If during the period of distribution of the Units there shall
be any change in Canadian Securities Laws that, in the opinion of the
Underwriters, acting reasonably, requires the filing of a Prospectus Amendment, Pretivm shall, to the satisfaction of the
Underwriters, acting reasonably, promptly prepare and file such Prospectus
Amendment with the appropriate Canadian Securities Regulator in each of the
Qualifying Provinces where such filing is required.

|10. | Underwriting Fee
|--- | ----------------

The Underwriters will be paid a fee of $0.50 per Purchased Unit
(the Underwriting Fee) sold pursuant to this Agreement. Such
Underwriting Fee shall be due and payable in full by Silver Standard at the
Closing Time (as defined below) against payment for the Purchased Units and, if
applicable, as to $0.50 per Additional Unit, $0.48 per Additional Share and/or
$0.04 per Additional Warrant, (as the case may be) by Silver Standard, at the
Option Closing Time, against payment for the Additional Units, Additional Shares
and/or Additional Warrants, as the case may be. The Underwriting Fee shall be
payable as provided for in section 11.

All fees, expenses and other payments under this Agreement
shall be paid without giving effect to any withholding or deduction of any tax
or similar governmental assessment. If Silver Standard is required by law to
deduct or withhold any amounts with respect to any such tax or assessment or if
any such tax or assessment is required to be paid by the Underwriters or any of
their affiliates as a result or arising out of this Agreement, Silver Standard
shall pay the Underwriters such additional amounts as shall be required so that
the net amount received by the Underwriters from Silver Standard after such
deduction, withholding or payment shall equal the amounts otherwise payable to
the Underwriters under this Agreement (provided that, for greater certainty,
Silver Standard shall have no obligations in respect of any income or other
similar taxes of the Underwriters). If any Goods and Services Tax, Harmonized
Sales Tax, and/or provincial sales taxes or other similar tax is payable with
respect to the fees paid or payable to the Underwriters under this engagement,
the Underwriters will add the amount of such tax to its invoice and Silver
Standard shall pay the Underwriters such tax.

|11. | Delivery of Purchase Price, Underwriting Fee and
      Certificates
|--- | -------------------------------------------------------------------

The purchase and sale of the Purchased Units and, if
applicable, the Additional Units and/or Additional Shares and/or Additional
Warrants shall be completed at the Closing Time and the Option Closing Time, as
the case may be, at the offices of Fasken Martineau DuMoulin LLP, 2900  550
Burrard Street, Vancouver, British Columbia, or at such other place as the
Underwriters, Pretivm and Silver Standard may agree upon.

At the Closing Time or the Option Closing Time, as the case may
be, the following certificates shall be duly and validly delivered to the
Underwriters, global certificates representing the Purchased Shares and
Purchased Warrants comprising the Purchased Units or the Additional Shares and
Additional Warrants issuable upon the exercise of the Over-Allotment Option, as
the case may be, registered in the name of CDS & Co. or in such other
nominee name or names for CDS as the Lead Underwriters may notify Pretivm in
writing not less than 24 hours prior to the Closing Time or the Option Closing
Time, as the case may be, and individual certificates for certain Substituted
Purchasers, against payment by the Underwriters, as directed by Silver Standard,
of the Purchase Price for the Purchased Units or the Additional Units (and/or
Additional Shares and/or Additional Warrants), as the case may be, by wire
transfer, in each case together with a receipt signed by the Lead Underwriters for
such definitive global certificates and for receipt of the Underwriting Fee.

---

- 36 -

In order to facilitate an efficient and timely closing at the
Closing Time and the Option Closing Time, the Underwriters may choose to
initiate a wire transfer of funds to Silver Standard or its counsel representing
the Purchase Price for the Purchased Units or the Additional Units (and/or
Additional Shares and/or Additional Warrants), as the case may be, prior to the
Closing Time or the Option Closing Time, as the case may be. If the Underwriters
do so, Silver Standard agrees that such transfer of funds to Silver Standard
prior to the Closing Time or the Option Closing Time does not constitute a
waiver by the Underwriters of any of the conditions of the Closing or the Option
Closing set out in this Agreement. Furthermore, Silver Standard agrees that any
such funds received from the Underwriters prior to the Closing Time or the
Option Closing Time, as the case may be, will be held in trust solely for the
benefit of the Underwriters until the Closing Time or the Option Closing Time,
as the case may be, and if the Closing or the Option Closing, as the case may
be, does not occur at the scheduled Closing Time or the Option Closing Time, as
the case may be, such funds shall be immediately returned by wire transfer to
the Lead Underwriters, on behalf of the Underwriters, without interest. Upon the
satisfaction of the conditions of the Closing or the Option Closing, as the case
may be, and the delivery to the Underwriters of the items set out in section 12,
the funds held in trust for the Underwriters shall be deemed to be delivered by
the Underwriters to Silver Standard in satisfaction of the obligation of the
Underwriters under this section 11 and upon such delivery the trust constituted
by this section 11 shall be terminated without further formality.

|12. | Closing Conditions
|--- | ------------------

The Underwriters obligation to purchase the Purchased Units at
the Closing Time shall be subject to the accuracy of the representations and
warranties of each of Pretivm and Silver Standard contained in this Agreement as
of the date of this Agreement and as of the Closing Date, the performance by
each of Pretivm and Silver Standard of their respective obligations under this
Agreement and the following conditions:

| | (c) | No Indemnity
| | --- | ------------

If and to the extent that a court of competent jurisdiction in
a final non-appealable judgment from which no appeal can be made or a
governmental authority in a final ruling from which no appeal can be made
determines that a Claim resulted from the criminal fraud, gross negligence or
wilful misconduct of the Indemnified Party claiming indemnity in connection with
its obligations under this Agreement, such Indemnified Party shall promptly
reimburse to the Indemnifiers any funds advanced to such Indemnified Party in
respect of such Claim and thereafter the indemnity provided for in section 14
shall cease to apply to such Indemnified Party in respect of such Claim. For
greater certainty, the parties agree that they do not intend that any failure by
the Underwriters to conduct such reasonable investigation as necessary to
provide the Underwriters with reasonable grounds for believing the Prospectus
and any Prospectus Amendment contained no misrepresentation shall constitute
criminal fraud, gross negligence or wilful misconduct for purposes of
section 14.

| | (d) | Notification of Claims
| | --- | ----------------------

If any Claim is asserted against any Indemnified Party in
respect of which indemnification is or might reasonably be considered to be
provided, such Indemnified Party will promptly after the date of the receipt by
the Indemnified Party of notice of, or of the Indemnified Party otherwise
becoming aware of, any such Claim (whether such Claim is asserted or
indemnification might be reasonably be considered to be provided) notify the
Indemnifiers of the nature of such Claim (the omission to so notify the
Indemnifiers of any potential Claim shall not relieve any Indemnifier from any
liability which it may have to any Indemnified Party and any omission to so
notify the Indemnifiers of any actual Claim shall affect the Indemnifiers
liability only to the extent that the Indemnifiers are prejudiced by that
failure). The Indemnifiers shall assume the defence of any suit brought to
enforce such Claim provided, however, that:

| | (i)  | the defence shall be conducted through legal counsel
      reasonably acceptable to the Indemnified Party, and

      may be made by the Indemnifiers without the prior written consent (such
      consent not to be unreasonably withheld or delayed) of the Indemnified
      Party, acting reasonably, unless such settlement includes an unconditional
      release of each of the Indemnified Parties from all liability arising out
      of such action or claim and does not include a statement as to or an
      admission of fault, culpability or failure to act, by or on behalf of any
      Indemnified Party.

The Indemnified Party and the Indemnifiers shall each cooperate
fully with the other in the defence of any Claim pursuant to which
indemnification is provided hereunder. Without limiting the generality of the
foregoing, each such person shall furnish to the other person (at the expense of
the Indemnifiers) such documentary or other evidence as is then in its
possession as may reasonably be requested by the other person for the purpose of
defending against any such Claim.

| | (e) | Right of Indemnity in Favour of
      Others
| | --- | --------------------------------------------

The Indemnifiers acknowledge and agree that the Underwriters
  are contracting on their own behalf and as agents for their respective
  affiliates, directors, officers, employees, partners, agents, advisors and
  shareholders and accordingly hereby constitute the Underwriters as trustees for
  any other Indemnified Party for the covenants of the Indemnifiers contained in
  this section 14 and the Underwriters agree to accept such trust and to hold such
  covenants on behalf of such persons.

| | (f) | Retaining Counsel
| | --- | -----------------

In any such Claim, the Indemnified Party shall have the right
to retain other counsel to act on his or its behalf, provided that the fees and
disbursements of such counsel shall be paid by the Indemnified Party unless: (i)
the applicable Indemnifier and the Indemnified Party shall have mutually agreed
to the retention of the other counsel; (ii) the named parties to any such Claim
(including any added third or impleaded party) include both the Indemnified
Party and an Indemnifier and the representation of both parties by the same
counsel would be inappropriate due to the actual or potential differing
interests between them; or (iii) the applicable Indemnifier shall not have
retained counsel within seven (7) Business Days following receipt by such
Indemnifier of notice of any such Claim from the Indemnified Party.

|15. | Contribution
|--- | ------------
|    |             
|    | (a)         

In order to provide for a just and equitable contribution in
circumstances in which the indemnity provided in section 14 would otherwise be
available in accordance with its terms but is, for any reason, held to be
unavailable to or unenforceable by the Underwriters or enforceable otherwise
than in accordance with its terms, Pretivm, Silver Standard and the
Underwriters, severally and not jointly, shall contribute to the aggregate of
all claims, expenses, costs and liabilities and all losses of a nature
contemplated by section 14 in such proportions as is appropriate to reflect: (i)
as among Pretivm, Silver Standard and the Underwriters, the relative fault of
Pretivm, Silver Standard and the Underwriters; and (ii) as among Silver
Standard, Pretivm and the Underwriters the cash proceeds ultimately received by
Silver Standard or Pretivm from this Agreement and the Related Agreements and
the Underwriting Fee received by the Underwriters pursuant to this Agreement.
Relative fault shall be determined by reference to, among other things, the
intent of such parties and their relative knowledge, access to information and
opportunity to correct or prevent such untrue statement or omission. Pretivm,
Silver Standard and the Underwriters agree that it would not be just and
equitable if contribution were determined by pro rata allocation or any other
method of allocation which does not take account of the equitable considerations
referred to above. Notwithstanding the provisions of this section 15(a), (A) the
Underwriters shall not in any event be liable to contribute, in the aggregate,
any amounts in excess of the aggregate Underwriting Fee or any portion of the
Underwriting Fee actually received by each of them; and (B) no party who has
been determined by a court of competent jurisdiction, in a final non-appealable
judgment from which no appeal can be made or a governmental authority in a final
ruling from which no appeal can be made, to have engaged in any criminal fraud,
gross negligence, fraudulent misrepresentation, wilful misconduct, reckless
disregard or intentional fault in connection with its obligations under this
Agreement shall be entitled to claim contribution from any person who has not
also been determined by a court of competent jurisdiction, in a final
non-appealable judgment from which no appeal can be made or a governmental authority in a final ruling from which no appeal
can be made, to have engaged in such criminal fraud, gross negligence,
fraudulent misrepresentation, wilful misconduct, reckless disregard or
intentional fault. For greater certainty, the parties agree that they do not
intend that any failure by the Underwriters to conduct such reasonable
investigation as necessary to provide the Underwriters with reasonable grounds
for believing the Prospectus and any Prospectus Amendment contained no
misrepresentation shall constitute criminal fraud, gross negligence,
fraudulent misrepresentation, wilful misconduct, reckless disregard or
intentional fault for purposes of section 15.

- 50 -

| | (b) | Rights of Contribution in Addition to Other
      Rights
| | --- | --------------------------------------------------------

The rights to contribution provided in this section 15 shall be
in addition to and not in derogation of any other right to contribution which
the Underwriters may have by statute or otherwise at law.

| | (c) | Calculation of
Contribution
| | --- | ---------------------------

In the event that an Indemnifier may be held to be entitled to
contribution from the Underwriters under the provisions of any statute or at
law, the Indemnifier shall be limited to contribution in an amount not exceeding
the lesser of:

| | (i)  | the portion of the full amount of the loss or liability
      giving rise to such contribution for which the Underwriters are
      responsible, as determined in section 15(a), and                                                                                                                
| | ---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
| |      |                                                                                                                                                                                                                                                                                                     
| | (ii) | the amount of the Underwriting Fee actually received by
      the Underwriters under this Agreement, and an Underwriter shall in no
      event be liable to contribute any amount in excess of such Underwriters
      portion of the Underwriting Fee actually received under this
    Agreement.

| | (d) | Notice
| | --- | ------

If the Underwriters have reason to believe that a claim for
contribution may arise, they shall give the Indemnifier notice of such claim in
writing, as soon as reasonably possible, but failure to notify the Indemnifier
shall not relieve the Indemnifier of any obligation which he or it may have to
the Underwriters under this section.

| | (e) | Right of Contribution in Favour of
  Others
| | --- | -------------------------------------------

The Indemnifiers acknowledge and agree that the Underwriters
are contracting on their own behalf and as agents for their respective
affiliates, directors, officers, employees, partners, agents, advisors and
shareholders.

|16. | Severability
|--- | ------------

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

---

- 51 -

|17. | Expenses
|--- | --------

Silver Standard will be responsible for all expenses relating
to the issue, sale and delivery of the Units and all expenses of or incidental
to all other matters in connection with the transaction set out in this
Agreement, including the fees, taxes and disbursements of the legal counsel,
auditors, roadshow consultants, printers and other consultants and service
providers retained by Pretivm or Silver Standard. In addition, Silver Standard
will reimburse the Underwriters for all reasonable out-of-pocket expenses
incurred by the Underwriters in connection with the transactions contemplated by
this Agreement, including, but not limited to, the fees, taxes and disbursements
of Underwriters legal counsel, advertising, printing, courier,
telecommunications, data searches, travel, any other expenses and the fees,
taxes and disbursements of experts retained by the Underwriters, together with
any related Goods and Services Tax (GST) and provincial sales taxes or
Harmonized Sales Tax (HST), as applicable, provided, however, that any
individual expense greater than $10,000, excluding legal fees, shall be subject
to Silver Standards written consent. Such reimbursements will be payable upon a
request for payment thereof by the Lead Underwriters.

|18. | Rights to Purchase
|--- | ------------------
|    |                   
|    | (a)               

The obligation of the Underwriters to purchase the Purchased
Units or the Additional Units, as the case may be at the Closing Time or on the
Option Closing Date, as the case may be, shall be several and not joint and
shall be limited to the percentage of the Purchased Units or the Additional
Units, as the case may be, set out opposite the name of the Underwriters
respectively below:

CIBC World Markets Inc.
    25%Citigroup Global Markets Canada Inc.
    22%UBS Securities Canada Inc.
    22%BMO Nesbitt Burns Inc.
    10%Dahlman Rose & Company, LLC
    7%GMP Securities L.P.
    7%Credit Suisse Securities (Canada),
      Inc.
    5%Salman Partners Inc.
    2%


Subject to section 18(c), in the event that any of the
Underwriters shall fail to purchase its applicable percentage of the Purchased
Units or the Additional Units, as the case may be, at the Closing Time or on the
Option Closing Date, as the case may be, the others shall be obligated,
severally (not jointly), to purchase on a pro rata basis all of the percentage
of the Purchased Units or the Additional Units, as the case may be, that would
otherwise have been purchased by the defaulting Underwriter(s); provided,
however, that in the event that the percentage of the total number of Purchased
Units or Additional Units, as the case may be, which the defaulting
Underwriter(s) has failed to purchase exceeds 10% of the total number of
Purchased Units or Additional Units, as the case may be, which the Underwriters
have agreed to purchase, the other Underwriters shall have the right, but shall
not be obligated, to purchase on a pro rata basis all of the percentage of the
total number of Purchased Units or Additional Units, as the case may be, that
would otherwise have been purchased by the defaulting Underwriter(s). In the
event that such right is not exercised, then Pretivm and Silver Standard shall
have the right to terminate their respective obligations hereunder without
liability except as set out below and the other Underwriters which are not in
default shall be relieved of all obligations to Pretivm and Silver Standard in
respect of the defaulting Underwriters Units. Nothing in this section 18(a)
shall oblige Pretivm or Silver Standard to sell to the Underwriters less than
all of the Purchased Units or the Additional Units, as the case may be, or
relieve from liability to Pretivm or Silver Standard any Underwriter which shall
be so in default. In the event of a termination by Pretivm or Silver Standard of
their respective obligations under this Agreement pursuant to this section 18,
there shall be no further liability on the part of Pretivm or Silver Standard to
the Underwriters except in respect of any liability which may have arisen or may
arise under sections 14, 15 and 17.

---

- 52 -

| | (b) | Purchases by Other
Underwriters
| | --- | -------------------------------

If the amount of the Purchased Units or the Additional Units,
as the case may be, which the remaining Underwriters wish to purchase pursuant
to section 18(a) exceeds the amount of the Purchased Units or the Additional
Units, as the case may be, which would otherwise have been purchased by an
Underwriter which is in default, such Purchased Units or the Additional Units,
as the case may be, shall be divided pro rata among the Underwriters desiring to
purchase such Purchased Units or the Additional Units, as the case may be, in
proportion to the percentage of Purchased Units or the Additional Units, as the
case may be, which such Underwriters have agreed to purchase as set out in
section 18(a).

| | (c) | Rights to Purchase of Other
  Underwriters
| | --- | ------------------------------------------

In the event that one or more but not all of the Underwriters
shall exercise their right of termination under section 13, the other
Underwriters shall have the right, but shall not be obligated, to purchase all
of the percentage of the Purchased Units or the Additional Units, as the case
may be, which would otherwise have been purchased by such Underwriters which
have so exercised their right of termination. If the amount of such Purchased
Units or the Additional Units, as the case may be, which the remaining
Underwriters wish, but are not obliged, to purchase exceeds the amount of such
Purchased Units or the Additional Units, as the case may be, which remain
available for purchase, such Purchased Units or the Additional Units, as the
case may be, shall be divided pro rata among the Underwriters desiring to
purchase such Purchased Units or the Additional Units, as the case may be, in
proportion to the percentage of Purchased Units or the Additional Units, as the
case may be, which such Underwriters have agreed to purchase as set out in
section 18(a).

|19. | Stabilization
|--- | -------------

In connection with the distribution of the Units, the
Underwriters and members of their selling group (if any) may over allot or
effect transactions which stabilize or maintain the market price of the Units at
levels other than those which might otherwise prevail in the open market or engage in such other activities as are set out under the
heading Price Stabilization, Short Positions and Passive Market Making in the
Prospectus, in compliance with applicable securities laws and the rules and
regulations of applicable stock exchanges and regulators. Those stabilizing
transactions, if any, may be discontinued at any time at the sole discretion of
the Underwriters.

---

- 53 -

|20. | Time
|--- | ----

Time is of the essence in the performance of the parties
respective obligations under this Agreement and the mere lapse of time shall
have the effects contemplated hereunder and by law.

|21. | Governing Law
|--- | -------------

This Agreement shall be governed by and construed in accordance
with the laws of the Province of British Columbia and the laws of Canada
applicable in the Province of British Columbia. Any judicial proceeding brought
against any of the parties to this Agreement with respect to any dispute arising
out of this Agreement or any matter related hereto may be brought only in the
courts of British Columbia, in the City of Vancouver, and by execution and
delivery of this Agreement, each of the parties to this Agreement accepts for
itself the exclusive jurisdiction in the aforesaid courts and irrevocably agrees
to be bound by any judgment rendered thereby in connection with this Agreement.

|23. | Authority of Lead
Underwriters
|--- | ------------------------------

The Lead Underwriters are hereby authorized by each of the
other Underwriters to act on its behalf and Pretivm and Silver Standard shall be
entitled to and shall act on any notice given in accordance with section 22 or
agreement entered into by or on behalf of the Underwriters by the Lead
Underwriters, each which represents and warrants that it has irrevocable
authority to bind the Underwriters, except in respect of any consent to a
settlement pursuant to section 14 and section 15, which indemnification and
contribution rights may be exercised by any of the Underwriters, a notice of
termination pursuant to section 13 which notice may be given by any of the
Underwriters, or any waiver pursuant to section 13(a), which waiver must be
signed by all of the Underwriters. The Lead Underwriters shall consult where
practical with the other Underwriters concerning any matter in respect of which
they act as representative of the Underwriters.

|24. | No Fiduciary Relationship
|--- | -------------------------

Each of Pretivm and Silver Standard hereby acknowledges that
the Underwriters are acting solely as underwriters in connection with the
purchase and sale of the Units contemplated hereby. Each of Pretivm and Silver
Standard further acknowledges that the Underwriters are acting pursuant to a
contractual relationship created solely by this Agreement entered into on an
arms length basis, and in no event do the parties intend that
the Underwriters act or be responsible as a fiduciary to Pretivm or Silver
Standard, their respective management, shareholders or creditors or any other
person in connection with any activity that the Underwriters may undertake or
have undertaken in furtherance of such purchase and sale of the Units, either
before or after the date hereof. The Underwriters hereby expressly disclaim any
