On behalf of Sprott Asset Management LP (Sprott), I am pleased to offer you an opportunity to exchange your Silver Bullion Trust units for units of Sprott Physical Silver Trust on a net asset value (NAV) to NAV, tax-deferred basis.

Sprott feels strongly that any investor in a physical bullion vehicle deserves a secure, convenient and exchange-traded alternative to actually holding physical silver that has reasonable redemption features, trades at or around the market value of the bullion that it holds, and is actively marketed to generate buying interest and enhanced trading liquidity.

Unfortunately, your units of Silver Bullion Trust units have traded at a persistent discount to the underlying value of the silver held by Silver Bullion Trust. Sprott believes this is the case because Silver Bullion Trust's management does not reinvest the fees it collects to market the product. Silver Bullion Trust also has a punitive redemption feature that does not allow you to take possession of your silver, but only entitles you to redeem your units for a cash amount that is significantly below the silver's market value.

Sprott is a global leader in precious metals investing and is committed to creating value for investors in our products. Sprott has the proven track record and best-in-class platform needed to address the persistent trading discounts endured by Silver Bullion Trust unitholders. Sprott Physical Silver Trust offers a physical redemption feature and Sprott actively markets the product to retail and institutional investors. We believe this commitment to marketing creates buying demand that supports the price of Sprott Physical Silver Trust units. As a result:

In addition, since the Sprott offer was announced, the discount at which Silver Bullion units were trading has narrowed by approximately 51%. However, if the Sprott offer is not successful, Sprott believes the price of Silver Bullion Trust units could decline to pre-Sprott announcement levels.

Here's how the exchange will work: The number of Sprott Physical Silver Trust units to be distributed to each Silver Bullion Trust unitholder will be determined on a NAV to NAV basis. For example, based on the NAV per unit of Sprott Physical Silver Trust and Silver Bullion Trust on May 22, 2015, you would receive approximately 1.5 Sprott Physical Silver Trust units for each Silver Bullion Trust unit tendered to the Sprott offer. You will not be required to pay any fee or commission to Sprott when you participate in this offer. Each unit carries the right to vote at Sprott Physical Silver Trust unitholder meetings. To allow you to exchange your Silver Bullion Trust units for Sprott Physical Silver Trust units on a tax-deferred basis for U.S. and Canadian income tax purposes, we are making available a "merger election", which we describe in the enclosed offer and circular.

Please act promptly as the offer will only be open for acceptance until 5:00 P.M. (EST) on July 6, 2015, unless the offer is extended or withdrawn.

For important information regarding the offer, we urge you to read the attached offer and circular in its entirety, including the risks described in Section 23 of the circular.

To tender your units please refer to the instructions in this offer and circular or call Kingsdale Shareholder Services at 1-888-518-6805 (toll free in North America) or at 1-416-867-2272 (outside of North America) or by e-mail at contactus@kingsdaleshareholder.com.

This document is important and requires your immediate attention. If you are in any doubt as to how to deal with it, you should consult your investment advisor, stockbroker, bank, trust company or other nominee.

This document does not constitute an offer or a solicitation to any person in any jurisdiction in which such offer or solicitation is unlawful.

However, the Offeror or its agents may, in the Offeror's sole discretion, take such action as the Offeror may deem necessary to make the Offer in any jurisdiction and extend the Offer to unitholders in such jurisdiction.

SPROTT ASSET MANAGEMENT SILVER BID LP
for consideration per SBT Unit consisting of units of

based on the relative Net Asset Value per unit
of Sprott Physical Silver Trust and Silver Bullion Trust
on the Expiry Date (as further described herein)

Sprott Asset Management Silver Bid LP (the "Offeror"), a limited partnership created under the laws of the Province of Ontario that is owned and controlled by Sprott Asset Management LP (the "Manager"), the manager of Sprott Physical Silver Trust, hereby offers (the "Offer") to purchase, on the terms and subject to the conditions set out herein, all of the issued and outstanding units (the "SBT Units") of Silver Bullion Trust ("SBT"), other than any SBT Units held directly or indirectly by the Offeror. The Offer comprises an exchange offer alternative (the "Exchange Offer Election") and a merger alternative (the "Merger Election"). Holders of SBT Units ("SBT Unitholders") that elect the Merger Election can exchange their SBT Units for PSLV Units based on the NAV to NAV Exchange Ratio (as defined below) on a tax-deferred basis for U.S. and Canadian income tax purposes. SBT Unitholders who wish to crystallize the realization of any gain (or loss) for Canadian income tax purposes may elect the Exchange Offer Election in order to exchange their SBT Units for PSLV Units based on the NAV to NAV Exchange Ratio and have the transaction treated as a taxable disposition for Canadian income tax purposes. The exchange of SBT Units under the Exchange Offer Election will only be treated as a taxable disposition for U.S. income tax purposes if the Merger (as defined herein) does not occur and otherwise the exchange of SBT Units should be treated with the Merger as a tax deferred transaction for U.S. income tax purposes. Sprott Physical Silver Trust will not be required to pay any fees, expenses and other related amounts incurred in connection with the Offer and the Merger Transaction. The Manager will pay all such fees, expenses and amounts. The Manager has agreed to indemnify Sprott Physical Silver Trust for all costs, expenses and damages, if any, incurred in connection with the Offer.

The Offer is open for acceptance until 5:00 p.m. (Toronto time) (the "Expiry Time") on July 6, 2015 (the "Expiry Date"), unless extended or withdrawn.

The SBT Units are listed on the Toronto Stock Exchange (the "TSX") under the symbols "SBT.U" (U.S. dollar denominated) and "SBT.UN" (Canadian dollar denominated). The units (the "PSLV Units") of Sprott Physical Silver Trust are listed on the TSX under the symbol "PHS.U" and NYSE Arca under the symbol "PSLV". Sprott Physical Silver Trust has applied to the TSX, and will apply to NYSE Arca, to list the PSLV Units offered hereunder on the TSX and on NYSE Arca, respectively. The TSX has provided its conditional approval of the listing of PSLV Units on the TSX in connection with the Offer and the Merger Transaction.

Time is of the essence. Send in your SBT Units with a completed YELLOW Letter of Transmittal to the Depositary or call your broker now to deposit.

will consist of: (i) the transfer of substantially all of the assets and liabilities of SBT (other than the Administration Agreement (as defined herein)) to Sprott Physical Silver Trust in exchange for PSLV Units; and (ii) the distribution of such PSLV Units to SBT Unitholders, on the basis of the NAV to NAV Exchange Ratio, on a redemption of the SBT Units, immediately following and conditional on take-up of, and payment for, SBT Units under the Offer. This is intended to provide the most consistent treatment possible to all SBT Unitholders, whether they are making the Exchange Offer Election or the Merger Election. The "NAV to NAV Exchange Ratio" means, for each SBT Unit, such number of PSLV Units as is equal to (A) the Net Asset Value per SBT Unit (as calculated, in accordance with the SBT Declaration of Trust (as defined herein) on the Expiry Date, including, in the case of SBT's silver bullion, the value thereof based on the London Bullion Association fixing price for silver bullion on the Expiry Date) divided by (B) the Net Asset Value per PSLV Unit (as calculated, in accordance with the PSLV Trust Agreement (as defined herein), on the Expiry Date, including, in the case of Sprott Physical Silver Trust's silver bullion, the value thereof based on the London Bullion Association fixing price for silver bullion on the Expiry Date).

SBT Unitholders who wish to participate in the Offer must make the Exchange Offer Election or the Merger Election, as applicable, in the Letter of Transmittal or through their broker or other nominee.

The Offer is conditional on, among other things, the number of SBT Units in respect of which an Exchange Offer Election or Merger Election has been made, together with the number of SBT Units held as of the Expiry Time by or on behalf of the Offeror, if any, representing at least 66²/3% of the then issued and outstanding SBT Units. Subject to applicable laws, the Offeror reserves the right to extend, withdraw and/or terminate the Offer and to not take up and pay for any SBT Units deposited under the Offer or proceed with the Merger Transaction, and/or amend the Offer unless each of the conditions of the Offer is satisfied or waived by the Offeror at or before the Expiry Time.

SBT Unitholders whose SBT Units are registered in their name and who wish to accept the Offer must properly complete and execute the accompanying Letter of Transmittal (printed on YELLOW paper), or a manually executed facsimile thereof, and deposit it, at or prior to the Expiry Time, together with certificate(s) representing their SBT Units and all other required documents, with Kingsdale Shareholder Services (in its capacity as depositary, the "Depositary") at its office in Toronto, Ontario, Canada specified in the Letter of Transmittal, in accordance with the instructions set out in the Letter of Transmittal (as set out in Section 3 of the Offer, "Manner of Acceptance — Letter of Transmittal"). Alternatively, registered SBT Unitholders may accept the Offer by following the procedures for book-entry transfer of SBT Units set out in Section 3 of the Offer, "Manner of Acceptance — Acceptance by Book-Entry Transfer". SBT Unitholders who hold their SBT Units with an investment advisor, stockbroker, bank, trust company or other nominee ("Beneficial SBT Unitholders") will not receive a Letter of Transmittal and should follow the instructions set out by such nominee to deposit their SBT Units.

Beneficial SBT Unitholders should contact their investment advisor, stockbroker, bank, trust company or other nominee for assistance if they wish to accept the Offer in order to take the necessary steps to be able to deposit such SBT Units under the Offer. Nominees will likely establish deposit cut-off times that are up to 48 hours prior to the Expiry Time. SBT Unitholders must instruct their investment advisor, stockbroker, bank, trust company or other nominee promptly if they wish to deposit.

SBT Unitholders will not be required to pay any fee or commission if they accept the Offer by depositing their SBT Units directly with the Depositary. An investment advisor, stockbroker, bank, trust company or other nominee through whom a SBT Unitholder holds SBT Units may charge a fee to deposit any such SBT Units on behalf of the SBT Unitholder. SBT Unitholders should consult such nominee to determine whether any charges will apply.

Questions and requests for assistance may be directed to Kingsdale Shareholder Services (in its capacity as information agent, the "Information Agent"), who can be contacted at 1-888-518-6805 toll free in North America or at 1-416-867-2272 outside of North America or by e-mail at contactus@kingsdaleshareholder.com or at the address indicated on the last page of this document and additional copies of this document, the Letter of Transmittal, or any documents incorporated by reference or otherwise related to the Offer, may be obtained, without charge, upon request from the Depositary and Information Agent at its offices shown on the last page of this document, and are accessible on the Canadian Securities Administrators' website at www.sedar.com and on EDGAR at www.sec.gov.

All of the forward looking information in the Offer and the Circular, is qualified by this cautionary note.

Forward looking information is not, and cannot be, a guarantee of future results or events. Forward looking information is based on, among other things, opinions, assumptions, estimates and analyses that, while considered reasonable by the Offeror at the date the forward looking information is provided, inherently are subject to significant risks, uncertainties, contingencies and other factors that may cause actual results and events to be materially different from those expressed or implied by the forward looking information.

•: the accuracy of SBT's public disclosure;

FREQUENTLY ASKED QUESTIONS

The following sets forth material information with respect to the Offer and the Merger Transaction. The questions and answers below are not meant to be a substitute for the more detailed description and information contained in the Offer and Circular and the Letter of Transmittal. You are urged to read the entire Offer and Circular and the Letter of Transmittal carefully prior to making any decision regarding whether or not to deposit your SBT Units. For ease of reference, cross-references are provided in this section to other sections of the Offer and Circular where you will find more complete descriptions of the topics mentioned below. Unless otherwise defined herein, capitalized terms have the meanings given to them in the Glossary.

BY DEPOSITING YOUR SBT UNITS IN THE OFFER, YOU ARE APPOINTING THE OFFEROR AS YOUR ATTORNEY AND PROXY HOLDER IN CERTAIN CIRCUMSTANCES, INCLUDING AS ATTORNEY IN CONNECTION WITH THE SPECIAL RESOLUTIONS THAT WILL AUTHORIZE THE MERGER TRANSACTION. SEE SECTION 3 OF THE OFFER, "MANNER OF ACCEPTANCE".

What is the Offeror proposing?

Exchange Offer Election and Merger Election

SBT Unitholders who deposit SBT Units and participate in the Offer may make the Exchange Offer Election or the Merger Election. SBT Unitholders that elect the Merger Election can exchange their SBT Units for PSLV Units based on the NAV to NAV Exchange Ratio on a tax-deferred basis for U.S. and Canadian income tax purposes. SBT Unitholders who wish to crystallize the realization of any gain (or loss) for Canadian income tax purposes may elect the Exchange Offer Election in order to exchange their SBT Units for PSLV Units based on the NAV to NAV Exchange Ratio and have the transaction treated as a taxable disposition for Canadian income tax purposes. The exchange of SBT Units under the Exchange Offer Election will only be treated as a taxable disposition for U.S. income tax purposes if the Merger does not occur and otherwise the exchange of SBT Units should be treated with the Merger as a tax deferred transaction for U.S. income tax purposes.

If the number of SBT Units in respect of which an Exchange Offer Election or Merger Election has been made, together with the number of SBT Units held as of the Expiry Time by or on behalf of the Offeror, if any, represents at least 66²/3% of the then issued and outstanding SBT Units, the Offeror's current intention is to complete the Merger. This will consist of: (i) the transfer of substantially all of the assets and liabilities of SBT (other than the Administration Agreement) to Sprott Physical Silver Trust in exchange for PSLV Units; and (ii) the distribution of such PSLV Units to SBT Unitholders, on the basis of the NAV to NAV Exchange Ratio, on a redemption of the SBT Units immediately following and conditional on take-up of and payment for Tendered SBT Units under the Offer. This is intended to provide the most consistent treatment possible to all SBT Unitholders, whether they are making the Exchange Offer Election and exchanging SBT Units for PSLV Units under the Offer or making the Merger Election and exchanging SBT Units for PSLV Units as a result of the Merger.

SBT Unitholders making the Exchange Offer Election will exchange their SBT Units for consideration per SBT Unit of such number of PSLV Units as is determined by the NAV to NAV Exchange Ratio, subject to the terms and conditions set forth in the Offer and Circular. An exchange of SBT Units for PSLV Units under the Exchange Offer Election will be treated as a taxable disposition for Canadian income tax purposes and should be treated with the Merger as a tax-deferred transaction for U.S. income tax purposes. To tender your SBT Units in the Offer, you must deposit your SBT Units in the Offer and make an Exchange Offer Election in your Letter of Transmittal or through your broker or other nominee.

SBT Unitholders making the Merger Election will exchange their SBT Units for such number of PSLV Units as is determined by the NAV to NAV Exchange Ratio on a tax-deferred basis for U.S. and Canadian income tax purposes so as to defer the realization of any gain (or loss) for U.S. or Canadian tax purposes. To participate in the Merger Transaction, you must deposit your SBT Units in the Offer and make a Merger Election in your Letter of Transmittal or through your broker or other nominee.

Time is of the essence. Send in your SBT Units with a completed YELLOW Letter of Transmittal to the Depositary or call your broker now to deposit.

If, for any reason, no election is made by a Depositing SBT Unitholder with respect to SBT Units deposited to the Offer, such SBT Unitholder will be deemed to have made a Merger Election in respect of such SBT Units.

Special Resolutions to Permit the Merger Transaction

The execution of a Letter of Transmittal (or, in the case of SBT Units deposited by book-entry transfer, the making of a book-entry transfer) irrevocably approves, and irrevocably constitutes, appoints and authorizes, effective from and after 4:58 p.m. (Toronto time) on the Expiry Date, the Offeror, each director and officer of SAM GP Inc. and any other person designated by the Offeror, as the true and lawful agent, attorney and attorney-in-fact of the holder of the SBT Units with respect to Deposited SBT Units, with full power of substitution (such power of attorney, being coupled with an interest, being irrevocable), in the name of and on behalf of such SBT Unitholder to vote, execute and deliver any and all instruments of proxy, authorizations, requisitions, resolutions (in writing or otherwise and including any counterparts thereof), consents and directions, in form and substance satisfactory to the Offeror approving, and in respect of, the Special Resolutions, which will be used to permit and authorize the Merger Transaction. The Special Resolutions Power of Attorney granted in the Letter of Transmittal to vote, execute and deliver any instruments of proxy, authorizations, requisitions, resolutions, consents or directions in respect of the Special Resolutions will only be used and relied upon if the Offeror intends to proceed with the take up of, and payment for, Tendered SBT Units.

In order to permit the Merger Transaction, prior to the Offeror taking up and paying for any Tendered SBT Units under the Offer, the Offeror currently intends to pass the Special Resolutions which will, among other things:

(i): effect certain amendments to the SBT Declaration of Trust;
(ii): authorize the Merger Transaction; and
(iii): in order to ensure the completion of the Merger, remove the current SBT Trustees (other than the Administrator Nominees) and appoint persons designated by the Offeror to replace such SBT Trustees.

See Section 1 of the Offer, "The Offer and the Merger Transaction", Section 3 of the Offer, "Manner of Acceptance", Section 4 of the Offer, "Conditions of the Offer" and Section 15 of the Circular "Merger Transaction — Special Resolutions". Additional powers and proxies are also contained in a Letter of Transmittal, see Section 3 of the Offer, "Manner of Acceptance".

What would I receive in exchange for my SBT Units under the Offer?

In the case of both the Exchange Offer Election and the Merger Election, the number of PSLV Units to be distributed to each SBT Unitholder will be determined based on the NAV to NAV Exchange Ratio, being, for each SBT Unit, such number of PSLV Units as is equal to: (A) the Net Asset Value per SBT Unit (as calculated, in accordance with the SBT Declaration of Trust, on the Expiry Date, including, in the case of SBT's silver bullion, the value thereof based on the London Bullion Association fixing price for silver bullion on the Expiry Date) divided by (B) the Net Asset Value per PSLV Unit (as calculated, in accordance with the PSLV Trust Agreement, on the Expiry Date, including, in the case of Sprott Physical Silver Trust's silver bullion, the value thereof based on the London Bullion Association fixing price for silver bullion on the Expiry Date).

By way of example, based on the Net Asset Value per unit of Sprott Physical Silver Trust and SBT as of May 22, 2015 (calculated in a manner consistent with the NAV to NAV Exchange Ratio), a SBT Unitholder would receive 1.5009 PSLV Units for each SBT Unit held.

No fractional PSLV Units will be issued pursuant to the Offer or the Merger Transaction. Where the aggregate number of PSLV Units to be issued to a SBT Unitholder under the Offer would result in a fraction of a PSLV Unit being issuable, the number of PSLV Units to be received by such SBT Unitholder will be rounded down to the nearest whole PSLV Unit.

Who is offering to purchase my SBT Units?

The Offeror is making the Offer. The Offeror is a limited partnership formed and organized on May 14, 2015 under the laws of the Province of Ontario, Canada. The only limited partner of the Offeror is the Manager and the only general partner of the Offeror is SAM Silver Bid GP, a wholly owned subsidiary of the Manager. The Manager manages Sprott Physical Silver Trust, a trust created to invest and hold substantially all of its assets in physical silver bullion. Sprott Physical Silver Trust invests primarily in long-term holdings of unencumbered, fully allocated, physical silver bullion. See Section 1 of the Circular, "The Offeror, Sprott Asset Management LP and Sprott Physical Silver Trust".

Why is the Offeror making the Offer?

See Section 1 of the Offer, "The Offer and the Merger Transaction" and Section 3 of the Circular, "Background to the Offer".

Why should SBT Unitholders participate in the Offer?

Enhanced Liquidity	ü	×
Global Brand Recognition	ü	×
Physical Redemption Feature	ü	×
Custodied by the Royal Canadian Mint	ü	×
Ongoing Marketing Support	ü	×

SBT Unitholders should consider the following factors in making a decision to participate in the Offer:

Best-in-Class Platform and Commitment to Product Marketing

•: The Offeror and the Manager believe that investors in physical bullion vehicles want a secure, convenient and exchange-traded alternative to actually holding physical silver that has reasonable redemption features, trades at or around the market value of the bullion it holds, and is appropriately marketed to generate buying interest and enhanced trading liquidity.
•: The Manager and the Offeror believe that SBT Units persistently trade at a discount to NAV because SBT management does not reinvest the fees it collects to support the product. Additionally, SBT features a punitive redemption feature that forces unitholders to redeem their units for less than market value. Unlike Sprott Physical Silver Trust, SBT does not allow its unitholders to redeem for physical silver.
•: The Manager is a global leader in precious metals investing and is committed to creating value for investors in its products. The Manager has a proven track record and best-in-class platform which it believes can assist in addressing the persistent trading discounts endured by SBT Unitholders. The Manager actively markets Sprott Physical Silver Trust to retail and institutional investors. The Manager believes that this commitment to marketing creates buying demand that supports the price of PSLV Units. These efforts are further supported by Sprott Physical Silver Trust's industry-leading physical redemption feature.
•: By supporting the Offer, SBT unitholders will have an opportunity to move into an investment vehicle that has consistently outperformed SBT, while also benefitting from a significantly larger asset base and increased liquidity.

Potential to Unlock Value

•: Based on the closing prices of the SBT Units and the PSLV Units on the TSX (SBT.U) and NYSE Arca, respectively, on April 22, 2015, being the last trading day prior to the public announcement of the Manager's intention to commence the Offer, the SBT Units were trading at a -10.3% discount to NAV while the PSLV Units were trading at a 1.07% PREMIUM to NAV. These spreads have been relatively consistent over a prolonged period of time.
•: Since the Manager announced its intention to commence the Offer on April 23, 2015, the discount to NAV at which the SBT Units have traded has narrowed by approximately 51%. The Offer unlocks approximately U.S.$4.95 million in SBT Unitholder value (based on the closing prices of the SBT Units and the PSLV Units on the TSX (SBT.UN) and NYSE Arca, respectively, on April 22, 2015 and the Bank of Canada noon rate of exchange for the U.S. dollar on May 22, 2015).
•: The Offeror and the Manager believe that the narrowing of this spread is a result of the announcement of the Manager's intention to commence the Offer. If the Offer is successful, the Manager and the Offeror believe that SBT Unitholders, by owning PSLV Units, will see a meaningful reduction in the persistent NAV discount impacting their current investment in SBT Units.

SBT Unitholder Support

•: The Manager has become aware that SBT's largest unitholder, Polar Securities, which owns or controls approximately 10.02% of the outstanding SBT Units, supports the Offer.

Silver Custodied by the Royal Canadian Mint

•: Unlike SBT, which stores its silver in a commercial bank vault, the silver held by Sprott Physical Silver Trust is stored more securely outside of the banking system, at the Royal Canadian Mint, under the guarantee and protection of the Canadian Federal Government.

Unique Opportunity to Exit SBT, an Underperforming and Conflicted Vehicle

•: The incumbent SBT Trustees have publicly asserted that SBT's expense ratio is "among the lowest" relative to comparable U.S. and Canadian bullion products. However, the Offeror believes SBT's expense ratio is high given the SBT Trustees' and the Administrator's limited scope of duties, responsibilities and actions, including the lack of any duties or responsibilities in connection with redeeming units for physical bullion.
•: The incumbent SBT Trustees, including the independent committee formed in response to the Polar Proposal, claim that they are independent from the Administrator and its owner J.C. Stefan Spicer. However, all of the incumbent SBT Trustees also sit, or have sat, on at least one of the boards of two other bullion funds managed by Mr. Spicer. In addition, a number of the incumbent SBT Trustees have participated in a variety of business ventures with Mr. Spicer. SBT Unitholders should evaluate for themselves whether the incumbent SBT Trustees are independent from Mr. Spicer and the Administrator.

See Section 4 of the Circular, "Reasons to Participate in the Offer".

issued and outstanding SBT Units; (ii) all governmental or regulatory approvals (including those of any stock exchange or other securities regulatory authorities) that are necessary to complete the Offer and the Merger Transaction, including the listing on the TSX and NYSE Arca of the PSLV Units issuable pursuant to the Offer and the Merger Transaction, having been obtained or concluded on terms and conditions reasonably satisfactory to the Offeror; (iii) the Special Resolutions Power of Attorney having been validly granted in respect of at least 66²/3% of the then issued and outstanding SBT Units and the Special Resolutions having been validly passed; (iv) SBT and Sprott Physical Silver Trust not being prohibited by applicable Law, or their respective constating documents, from completing the Merger Transaction; and (v) the absence of any Material Adverse Change in relation to SBT. See Section 4 of the Offer, "Conditions of the Offer", for a complete list of the conditions to the Offer.

What securities are being sought in the Offer?

Pursuant to the Offer, the Offeror is offering to purchase all of the issued and outstanding SBT Units. The Offeror is also making available the Merger Election whereby SBT Unitholders will have the opportunity to exchange their SBT Units for such number of PSLV Units as is determined by the NAV to NAV Exchange Ratio on a tax-deferred basis for U.S. and Canadian income tax purposes so as to defer the realization of any gain (or loss) for U.S. or Canadian tax purposes.

Based on SBT's public disclosure, the Offeror believes that, as of May 22, 2015, there were 5,467,228 SBT Units issued and outstanding. See Section 1 of the Offer, "The Offer and the Merger Transaction".

How many PSLV Units could be issued in connection with the Offer?

Based on the Net Asset Value per unit (calculated in a manner consistent with the NAV to NAV Exchange Ratio) of Sprott Physical Silver Trust and SBT as of May 22, 2015, Sprott Physical Silver Trust expects to issue approximately 8,205,762 PSLV Units in connection with the Offer and the Merger Transaction. See Section 1 of the Offer, "The Offer and the Merger Transaction".

Will my ownership and voting rights as a unitholder of Sprott Physical Silver Trust be the same as my ownership and voting rights as a unitholder of SBT?

As noted above, Sprott Physical Silver Trust expects to issue approximately 8,205,762 PSLV Units in connection with the Offer and the Merger Transaction, which would result in there being a total of approximately 135,565,977 PSLV Units issued and outstanding (based on the number of PSLV Units issued and outstanding as at May 22, 2015 and calculated in a manner consistent with the NAV to NAV Exchange Ratio), with SBT Unitholders holding approximately 6.05% of the issued and outstanding PSLV Units. Each SBT Unit carries the right to one vote at meetings of SBT Unitholders. Each PSLV Unit carries the right to one vote at meetings of unitholders of Sprott Physical Silver Trust. See Section 8 of the Circular, "Certain Information Concerning the Securities of Sprott Physical Silver Trust — Authorized and Outstanding Units", Section 14 of the Circular, "Summary Comparison of Material Differences between the PSLV Trust Agreement and the SBT Declaration of Trust and of the Canadian Securities Regulatory Regime for Investment Funds and Public Companies" and Section 23 of the Circular, "Risk Factors".

You must make an Exchange Offer Election or a Merger Election, as applicable, in the Letter of Transmittal or through your broker or other nominee.

What if I have lost my SBT Unit certificate(s) but wish to deposit my SBT Units in the Offer?

If any certificate representing SBT Units has been lost, stolen or destroyed, the registered holder of such SBT Units should complete the Letter of Transmittal as fully as possible and forward it, together with an affidavit regarding the loss, theft or destruction, to the Depositary. The Depositary will assist in making arrangements for the necessary affidavit (which will include a bonding requirement) for payment in accordance with the Offer. Further details are set out in the Letter of Transmittal. The registered holder will be required to indemnify the Offeror, the Manager, SAM Silver Bid GP, SAM GP Inc.

See Section 3 of the Offer, "Manner of Acceptance".

If I make the Exchange Offer Election or the Merger Election, when will I receive the consideration for my SBT Units?

Exchange Offer Electing SBT Unitholders

If you are an Exchange Offer Electing SBT Unitholder and:

(i): the conditions of the Offer are satisfied or waived; and
(ii): the Offeror consummates the Offer and takes up, and pays for, Tendered SBT Units;

you will receive the consideration for your Tendered SBT Units as soon as practicable and, in any event, within three business days after the Offeror has taken up the Tendered SBT Units.

Merger Electing SBT Unitholders

If you are a Merger Electing SBT Unitholder and:

you will receive the consideration for your Merger Elected SBT Units as soon as practicable following the completion of the Merger.

See Section 6 of the Offer, "Take-Up and Payment for Tendered SBT Units".

What happens if I do not deposit my SBT Units in the Offer but holders of more than 66²/3% of SBT Units do?

If SBT Unitholders representing more than 66²/3% of the issued and outstanding SBT Units deposit their SBT Units in the Offer (whether making the Exchange Offer Election or the Merger Election) and do not withdraw them prior to 4:58 p.m. (Toronto time) on the Expiry Date, then the Special Resolutions will be approved. If the Special Resolutions are approved and the Merger is completed then SBT Unitholders that have not deposited SBT Units in the Offer, or Non-Depositing SBT Unitholders, will receive PSLV Units under the Merger as if they had deposited and made a Merger Election. See Section 12 of the Offer, "SBT Units Not Deposited Under the Offer".

Who is the Depositary under the Offer?

Kingsdale Shareholder Services is acting as the Depositary under the Offer. The Depositary will be responsible for receiving certificates representing SBT Units and accompanying Letters of Transmittal and other documents. The Depositary is also responsible for giving notices, if required, and making payment for all SBT Units purchased by the Offeror under the terms of the Offer and for all SBT Units to be redeemed as part of the Merger Transaction. The Depositary will also facilitate book-entry deposits of SBT Units. See Section 27 of the Circular, "Depositary".

Will I be able to withdraw previously deposited SBT Units?

Yes. You may withdraw SBT Units previously deposited by you: (i) at any time before SBT Units deposited under the Offer are taken up by the Offeror under the Offer; (ii) if your SBT Units have not been paid for by the Offeror within three business days after having been taken up; and (iii) in certain other circumstances described in Section 8 of the Offer, "Withdrawal of Deposited SBT Units". You must send a notice of withdrawal to the Depositary prior to the occurrence of certain events and within the time periods set forth in Section 8 of the Offer, "Withdrawal of Deposited SBT Units", and the notice must contain the specific information outlined therein.

In addition to the withdrawal mechanism described above, Merger Electing SBT Unitholders must deposit their Merger Elected SBT Units in the Offer in order to make the Merger Election and then will be deemed to have withdrawn such Merger Elected SBT Units from the Offer, effective at 4:59 p.m. (Toronto time) on the Expiry Date. Accordingly, Merger Elected SBT Units will not be taken-up and paid for under the Offer but, if the Merger is completed, such Merger Elected SBT Units will participate in the Merger and Merger Electing SBT Unitholders will receive PSLV Units upon the redemption of their SBT Units as part of the Merger Transaction. The deemed withdrawal will neither revoke the Special Resolutions Power of Attorney nor require the Depositary to return the Merger Elected SBT Units.

Will I have to pay any fees or commissions in connection with depositing my SBT Units?

If you are the registered owner of your SBT Units and you deposit your SBT Units directly to the Depositary, you will not have to pay brokerage fees or incur similar expenses. If you own your SBT Units through an investment advisor, stockbroker, bank, trust company or other nominee and your nominee deposits the SBT Units on your behalf, your nominee may charge you a fee for doing so. You should consult your nominee to determine whether any charges will apply.

What will happen if the Offer is withdrawn?

Unless all of the conditions to the Offer have been satisfied or waived at or prior to the Expiry Time, including that the Merger Transaction must be capable of completion, the Offeror will not be obligated to take

up and pay for SBT Units deposited to the Offer and the Offeror may withdraw the Offer. In such circumstances, the Merger Transaction will not proceed. If the Offer is withdrawn in this manner, all of your SBT Units that were deposited and not withdrawn will be returned to you with no payment.

How will a SBT Unitholder be treated for Canadian federal income tax purposes?

Disposition of SBT Units Pursuant to the Exchange Offer Election

In general, a disposition of SBT Units held as capital property by an Exchange Offer Electing SBT Unitholder in exchange for PSLV Units will give rise to a capital gain (or a capital loss) equal to the amount by which the proceeds of disposition of the Tendered SBT Units, net of any costs of disposition, exceed (or are less than) the adjusted cost base of the Tendered SBT Units to the Exchange Offer Electing SBT Unitholder immediately prior to the disposition. The proceeds of disposition of the Tendered SBT Units will generally be equal to the aggregate of the fair market value of the PSLV Units received in exchange therefor. The cost for tax purposes of the PSLV Units received in exchange for Tendered SBT Units will be equal to the fair market value of such PSLV Units. An Exchange Offer Electing SBT Unitholder who is not resident in Canada will not be subject to tax in respect of any capital gain realized on the disposition of Tendered SBT Units unless such SBT Units constitute "taxable Canadian property" of such SBT Unitholder for purposes of the Tax Act.

Transfer of SBT Assets to Sprott Physical Silver Trust Pursuant to the Merger

The Merger will constitute a "qualifying exchange" as defined in section 132.2 of the Tax Act, thereby allowing substantially all of the assets and liabilities of SBT (other than the Administration Agreement) to be transferred to Sprott Physical Silver Trust for proceeds of disposition equal to the tax cost of such assets. In such circumstances, there should be no taxable income to SBT arising from the transfer and, as a result there should be no tax liability to SBT Unitholders resulting from the transfer.

Disposition of SBT Units by SBT Unitholders Pursuant to the Merger

As noted above, the Merger will constitute a "qualifying exchange" as defined in section 132.2 of the Tax Act. Accordingly, where a Merger Electing SBT Unitholder or a Non-Depositing SBT Unitholder disposes of SBT Units to SBT in exchange for PSLV Units on the redemption of SBT Units pursuant to the Merger, the SBT Unitholder's proceeds of disposition for the SBT Units disposed of, and the cost to the SBT Unitholder of the PSLV Units received in exchange therefor, will be deemed to be equal to the adjusted cost base to the SBT Unitholder of the SBT Units immediately prior to their disposition. For the purpose of determining the adjusted cost base of the PSLV Units acquired by a SBT Unitholder on such exchange, the cost of such PSLV Units will be determined by averaging their cost with the adjusted cost base of all other PSLV Units held as capital property by such SBT Unitholder immediately before the exchange.

SBT will not realize a gain or loss on the transfer of the PSLV Units to the SBT Unitholders on the redemption of SBT Units.

The foregoing is only a brief summary of certain Canadian federal income tax consequences and is qualified by the description of certain Canadian federal income tax considerations in Section 20 of the Circular, "Certain Canadian Federal Income Tax Considerations". SBT Unitholders are urged to consult their own tax advisors to determine the particular tax consequences to them of an exchange of SBT Units pursuant to the Exchange Offer Election or a disposition of SBT Units pursuant to the Merger, or any other disposition in connection with the Offer.

Merger Transaction were treated as a Reorganization, subject to the passive foreign investment company ("PFIC") rules discussed below under "Certain United States Federal Income Tax Considerations", a U.S. Holder that exchanged SBT Units for PSLV Units pursuant to the Exchange Offer Election or the Merger Transaction generally would not recognize gain or loss on the exchange. A U.S. Holder's initial aggregate tax basis in the PSLV Units received would be equal to the U.S. Holder's aggregate adjusted tax basis in the SBT Units exchanged, and a U.S. Holder's holding period in the PSLV Units received would include the U.S. Holder's holding period in the SBT Units exchanged.

The foregoing is only a brief summary of certain United States federal income tax consequences and is qualified by the description of certain United States federal income tax considerations in Section 21 of the Circular, "Certain United States Federal Income Tax Considerations". SBT Unitholders are urged to consult their own tax advisors to determine the particular tax consequences to them of an exchange of SBT Units pursuant to the Exchange Offer Election or a disposition of SBT Units pursuant to the Merger, or any other disposition in connection with the Offer.

What is the market value of my SBT Units?

On April 22, 2015, the last trading day prior to the announcement by the Manager of the intention to make the Offer, the closing price of the SBT Units (SBT.UN) listed on the TSX was U.S.$8.29 (based on the Bank of Canada noon rate of exchange for the U.S. dollar on May 22, 2015). The volume-weighted average price of the SBT Units (SBT.UN) on the TSX for the 20 trading days ended April 22, 2015 was U.S.$8.66 (based on the Bank of Canada noon rate of exchange for the U.S. dollar on May 22, 2015). Based on the volume-weighted average prices of the PSLV Units on NYSE Arca for the 20 trading days ended April 22, 2015, the Offer consideration represented a premium of approximately 11.6% over the volume-weighted average price of the SBT Units (SBT.UN) on the TSX for the same period (the amount of consideration being calculated in a manner consistent with the NAV to NAV Exchange Ratio as at May 22, 2015). Based on the closing price of the PSLV Units on NYSE Arca, on April 22, 2015, the Offer consideration represented a premium of approximately 11.7% over the closing price of the SBT Units on the TSX on the same date (the amount of consideration being calculated in a manner consistent with the NAV to NAV Exchange Ratio as at May 22, 2015).

The Offeror urges you to obtain recent quotations for SBT Units and PSLV Units before deciding whether or not to deposit your SBT Units in the Offer. See Section 19 of the Circular, "Effect of the Offer and the Merger Transaction on the Market for and Listing of SBT Units and Status as a Reporting Issuer".

SUMMARY

The following is a summary only and is qualified in its entirety by the detailed provisions contained in this Offer and Circular. You should read this Offer and Circular in their entirety. Certain capitalized and other terms used in this summary, where not otherwise defined herein, are defined in the Glossary. All currency amounts expressed herein, unless otherwise indicated, are in United States dollars.

Except as otherwise expressly indicated herein, the information concerning SBT contained in this Offer and Circular has been taken from and is based solely upon SBT's public disclosure on file with the Canadian Securities Regulatory Authorities. SBT has not reviewed this Offer and Circular and has not confirmed the accuracy and completeness of the information in respect of SBT contained in this Offer and Circular. Although the Offeror, the Manager, Sprott Physical Silver Trust, SAM Silver Bid GP and SAM GP Inc. have no knowledge that would indicate that any information or statements contained in this Offer and Circular concerning SBT taken from, or based upon, such public disclosure contain any untrue statement of a material fact or omit to state a material fact that is required to be stated or that is necessary to make a statement not misleading in light of the circumstances in which it was made, none of the Offeror, the Manager, Sprott Physical Silver Trust, SAM Silver Bid GP, SAM GP Inc. or any of the directors or officers of the Manager, SAM GP Inc. or SAM Silver Bid GP has verified, nor do they assume any responsibility for, the accuracy or completeness of such information or statements or for any failure by SBT to disclose events or facts which may have occurred or which may affect the significance or accuracy of any such information or statements but which are unknown to the Offeror, the Manager, Sprott Physical Silver Trust, SAM Silver Bid GP and SAM GP Inc. Except as otherwise indicated, information concerning SBT is given based on information in SBT's public disclosure available as of May 22, 2015. All references to the number of SBT Units outstanding as May 22, 2015 in this Offer and Circular are references to estimates of such figures based solely on SBT's public disclosure.

The Offer and Merger Transaction

If the number of SBT Units in respect of which an Exchange Offer Election or Merger Election has been made, together with the number of SBT Units held as of the Expiry Time by or on behalf of the Offeror, if any, represents at least 66²/3% of the then issued and outstanding SBT Units, the Offeror's current intention is to complete the Merger. This will consist of: (i) the transfer of substantially all of the assets and liabilities of SBT (other than the Administration Agreement) to Sprott Physical Silver Trust in exchange for PSLV Units; and (ii) the distribution of such PSLV Units to SBT Unitholders, on the basis of the NAV to NAV Exchange Ratio, on a redemption of the SBT Units, immediately following and conditional on take-up of and payment for Tendered SBT Units under the Offer. This is intended to provide the most consistent treatment possible to all SBT Unitholders, whether they are making the Exchange Offer Election and exchanging SBT Units for PSLV Units under the Offer or making the Merger Election and exchanging SBT Units for PSLV Units as a result of the Merger.

If for any reason you deposit your SBT Units in the Offer but make no election (i.e. an Exchange Offer Election or a Merger Election), you will be deemed to have made a Merger Election in respect of such SBT Units.

Special Resolutions to Permit the Merger Transaction

In order to permit the Merger Transaction, prior to the Offeror taking up any Tendered SBT Units under the Offer, the Offeror currently intends to pass the Special Resolutions which will, among other things:

(i): effect certain amendments to the SBT Declaration of Trust;
(ii): authorize the Merger Transaction; and
(iii): in order to ensure the completion of the Merger Transaction, remove the current SBT Trustees (other than the Administrator Nominees) and appoint persons designated by the Offeror to replace such SBT Trustees,

in each case by resolutions in writing to be signed by SBT Unitholders holding 66²/3% or more of the outstanding SBT Units rather than seeking SBT Unitholders' approval at a special meeting called for that purpose, all in accordance with the SBT Declaration of Trust. The Offeror intends to use the Special Resolutions Power of Attorney to pass the Special Resolutions before the Offeror takes up Tendered SBT Units. Such resolutions in writing, being the Special Resolutions, include:

(i): amending Section 13.6 of the SBT Declaration of Trust to provide that a compulsory acquisition may be effected if the Offeror and its affiliates, after the take-up of, and payment for, SBT Units deposited under the Offer, hold not less than 66²/3% of the outstanding SBT Units (calculated on a fully-diluted basis, including any SBT Units held by or on behalf of or issuable to the Offeror or any affiliate or associate of the Offeror) and authorizing the Offeror to execute an amendment to the SBT Declaration of Trust in connection with the foregoing;
(ii): approving and authorizing the Merger Transaction, and any ancillary matters in connection therewith, and authorizing the Offeror to execute, on behalf of SBT, the Merger Agreement in connection with the Merger Transaction on substantially the terms described in the Offer and Circular;
(iii): amending the SBT Declaration of Trust to provide, in connection with the Merger, following the transfer of all of the assets and liabilities of SBT (other than the Administration Agreement) to Sprott Physical Silver Trust in exchange for PSLV Units, for the retention or reacquisition of one SBT Unit by the Offeror as provided in the Merger Agreement, if advisable, and subject to the foregoing, for the redemption of all outstanding SBT Units and the distribution of such PSLV Units to the SBT Unitholders on the basis of the NAV to NAV Exchange Ratio (and the cancellation of any such PSLV Units received by the Offeror itself) in full and final satisfaction of such SBT Unitholders' rights, and authorizing the Offeror to execute an amendment to the SBT Declaration of Trust in connection with the foregoing;
(iv): amending the SBT Declaration of Trust to permit the Offeror, notwithstanding anything to the contrary contained therein, to vote, execute and deliver any instruments of proxy, authorizations, requisitions, resolutions or consents in respect of any SBT Units taken up under the Offer or otherwise

The Offeror, Sprott Asset Management LP and Sprott Physical Silver Trust

Sprott Physical Silver Trust was established on June 30, 2010 under the laws of the Province of Ontario, Canada, pursuant to the PSLV Trust Agreement.

PSLV Units are listed on the TSX and NYSE Arca under the symbols "PHY.U" and "PSLV", respectively. See Section 1 of the Circular, "The Offeror, Sprott Asset Management and Sprott Physical Silver Trust".

SBT

SBT is a passive, self-governing, single purpose, closed-end trust with voting units established on June 8, 2009 under the laws of the Province of Ontario. SBT was created to acquire, hold and secure silver bullion on behalf of investors and to provide investors with exchange-tradeable units of ownership.

The SBT Units are listed on the TSX under the symbols "SBT.U" (U.S. dollar denominated) and "SBT.UN" (Canadian dollar denominated). See Section 2 of the Circular, "SBT".

SBT Unitholders should consider the following factors in making a decision to participate in the Offer:

Best-in-class platform and commitment to product marketing

•: The Offeror and the Manager believe that investors in physical bullion vehicles want a secure, convenient and exchange-traded alternative to actually holding physical silver that has reasonable redemption features, trades at or around the market value of the bullion it holds, and is appropriately marketed to generate buying interest and enhanced trading liquidity.
•: The Manager and the Offeror believe that SBT units persistently trade at a discount to NAV because SBT management does not reinvest the fees it collects to support the product. Additionally, SBT features a punitive redemption feature that forces unitholders to redeem their units for less than market value. Unlike Sprott Physical Silver Trust, SBT does not allow its unitholders to redeem for physical silver. The Manager actively markets Sprott Physical Silver Trust to retail and institutional investors.
•: The Manager is a global leader in precious metals investing and is committed to creating value for investors in its products. The Manager has a proven track record and best-in-class platform which it believes can assist in addressing the persistent trading discounts endured by SBT Unitholders. The Manager believes that this commitment to marketing creates buying demand that supports the price of PSLV Units. These efforts are further supported by Sprott Physical Silver Trust's industry-leading physical redemption feature.
•: By supporting the Offer, SBT unitholders will have an opportunity to move into an investment vehicle that has consistently outperformed SBT, while also benefitting from a significantly larger asset base and increased liquidity.

Potential to unlock value

•: Based on the closing prices of the SBT Units and the PSLV Units on the TSX (SBT.UN) and NYSE Arca, respectively, on April 22, 2015, being the last trading day prior to the public announcement of the Manager's intention to commence the Offer, the SBT Units were trading at a -10.3% discount to NAV while the PSLV Units were trading at a 1.07% PREMIUM to NAV. These spreads have been relatively consistent over a prolonged period of time.
•: Since the Manager announced its intention to commence the Offer on April 23, 2015, the discount to NAV at which the SBT Units have traded has narrowed by approximately 51%. The Offer unlocks approximately U.S.$4.95 million in SBT Unitholder value (based on the closing prices of the SBT Units and the PSLV Units on the TSX (SBT.UN) and NYSE Arca, respectively, on April 22, 2015 and the Bank of Canada noon rate of exchange for the U.S. dollar on May 22, 2015).
•: The Offeror and the Manager believe that the narrowing of this spread is a result of the announcement of the Manager's intention to commence the Offer. If the Offer is successful, the Manager and the Offeror believe SBT Unitholders, by owning PSLV Units, will see a meaningful reduction in the persistent NAV discount impacting their current investment in SBT Units.

SBT Unitholder Support

•: The Manager has become aware that SBT's largest unitholder, Polar Securities, which owns or controls approximately 10.02% of the outstanding SBT Units, supports the Offer.

Silver Custodied by the Royal Canadian Mint

•: Unlike SBT, which stores its silver in a commercial bank vault, the silver held by Sprott Physical Silver Trust is stored more securely outside of the banking system, at the Royal Canadian Mint, under the guarantee and protection of the Canadian Federal Government.

Unique Opportunity to Exit SBT, an Underperforming and Conflicted Vehicle

•: The incumbent SBT Trustees have publicly asserted that SBT's expense ratio is "among the lowest" relative to comparable U.S. and Canadian bullion products. However, the Offeror believes SBT's expense ratio is high given the SBT Trustees' and the Administrator's limited scope of duties, responsibilities and actions, including the lack of any duties or responsibilities in connection with redeeming units for physical bullion.
•: The incumbent SBT Trustees, including the independent committee formed in response to the Polar Proposal, claim that they are independent from the Administrator and its owner J.C. Stefan Spicer. However, all of the incumbent SBT Trustees also sit, or have sat, on at least one of the boards of two other bullion funds managed by Mr. Spicer. In addition, a number of the incumbent SBT Trustees have participated in a variety of business ventures with Mr. Spicer. SBT Unitholders should evaluate for themselves whether the incumbent SBT Trustees are independent from Mr. Spicer and the Administrator.

See Section 4 of the Circular, "Reasons to Participate in the Offer".

Purpose of the Offer and the Offeror's Plans for SBT

The Offeror is making the Offer to enable SBT Unitholders to become PSLV Unitholders and benefit from Sprott Physical Silver Trust's commitment to product marketing, physical redemption features, significantly larger asset base and increased liquidity. See Section 1 of the Offer, "The Offer and the Merger Transaction" and Section 3 of the Circular, "Background to the Offer".

If permitted by applicable Law and otherwise advisable, subsequent to the completion of the Offer and the Merger Transaction, if necessary, the Offeror will consider taking steps to cause the delisting of the SBT Units from the TSX and to cause SBT to cease to be a reporting issuer under the securities laws of each of the

See Section 3 of the Offer, "Manner of Acceptance by Book-Entry Transfer".

SBT Unitholders will not be required to pay any fee or commission if they participate in the Offer by depositing their SBT Units directly with the Depositary. An investment advisor, stockbroker, bank, trust company or other nominee through whom a SBT Unitholder holds SBT Units may charge a fee to deposit any such SBT Units on behalf of the SBT Unitholder. SBT Unitholders should consult such nominee to determine whether any charges will apply.

Persons whose SBT Units are registered in the name of an investment advisor, stockbroker, bank, trust company or other nominee should contact such nominee for assistance if they wish to participate in the Offer in order to take the necessary steps to be able to deposit such SBT Units under the Offer. Nominees will likely establish depositing cut-off times that are up to 48 hours prior to the Expiry Time. SBT Unitholders must instruct their investment advisor, stockbroker, bank, trust company or other nominee promptly if they wish to deposit.

SBT Unitholders should contact the Depositary and Information Agent, their investment advisor, stockbroker, bank, trust company or other nominee for assistance in participating in the Offer and depositing SBT Units with the Depositary. The Information Agent can be contacted at 1-888-518-6805 toll free in North America or at 1-416-867-2272 outside of North America or by e-mail at contactus@kingsdaleshareholder.com.

In order not to provide the Special Resolutions Power of Attorney, withdrawals of Deposited SBT Units must be effected prior to 4:58 p.m. (Toronto time) on the Expiry Date. A notice of withdrawal of such Deposited SBT Units must actually be received by the Depositary prior to 4:58 p.m. (Toronto time) on the Expiry Date in a manner such that the Depositary has a written or printed copy of such notice of withdrawal.

A Depositing SBT Unitholder's broker or other nominee may set deadlines for the withdrawal of Elected SBT Units that are earlier than those specified above and Electing SBT Unitholders should contact their broker or other nominee for further details or assistance.

Appointment as Proxy Holder and Attorney from Time of Deposit

person designated by the Offeror, with full power of substitution, as the Depositing SBT Unitholder's nominee and proxy in respect of any meeting or meetings (whether annual, special or otherwise, or any adjournments or postponements thereof) of SBT Unitholders in respect of matters related to the Offer, the Merger Transaction, the nomination, election or removal of SBT Trustees, any amendments or action related to the SBT Declaration of Trust, the Administration Agreement, the Storage Agreement or any other matter that would materially and adversely impact, or otherwise frustrate, the Offer, the Merger Transaction or matters related to (including approval of) the Offer or the Merger Transaction (or substantially similar transactions), for all Deposited SBT Units; and (ii) irrevocably approves, and irrevocably constitutes, appoints and authorizes the Offeror, each director and officer of SAM GP Inc. and any other person designated by the Offeror, as the true and lawful agent, attorney and attorney-in-fact of the holder of the SBT Units with respect to Deposited SBT Units, with full power of substitution (such power of attorney, being coupled with an interest, being irrevocable), in the name of and on behalf of such SBT Unitholder to: (A) requisition and call (and receive and execute all forms, proxies, securityholder proposals and other documents and take other steps needed to requisition and call) any meeting or meetings (whether annual, special or otherwise, or any adjournments or postponements thereof) of SBT Unitholders; or (B) exercise any rights of redemption under the SBT Declaration of Trust in respect of such Deposited SBT Units provided such redemption would occur at a redemption price equal to 100% of the NAV of the Deposited SBT Unit and such redemption is only consummated following the Offeror having taken up and paid for such Deposited SBT Units.

Upon such appointment, all prior proxies and other authorizations (other than the Special Resolutions Power of Attorney, but including, without limitation, all appointments of any agent, attorney or attorney-in-fact) or consents given by the Depositing SBT Unitholder with respect to such Depositing SBT Unitholder's Deposited SBT Units will be revoked and no subsequent proxies or other authorizations or consents may be given by such person with respect thereto.

In order not to appoint the Offeror, or any other person designated by the Offeror, as a Depositing SBT Unitholder's nominee and proxy holder as described above, such Depositing SBT Unitholder must withdraw its Deposited SBT Units prior to the Expiry Time. A notice of withdrawal of such Deposited SBT Units must actually be received by the Depositary in a manner such that the Depositary has a written or printed copy of such notice of withdrawal.

Conditions of the Offer

Subject to applicable Law, the Offeror reserves the right to withdraw or terminate the Offer and not take up and pay for any SBT Units deposited under the Offer, and/or to extend the period of time during which the Offer is open for acceptance and postpone taking up and paying for any SBT Units deposited under the Offer, and/or to amend the Offer, unless all of the conditions described in Section 4 of the Offer, "Conditions of the Offer", are satisfied or waived by the Offeror at or before the Expiry Time. These conditions include, among others: (i) the number of SBT Units held by Depositing SBT Unitholders, together with the number of SBT Units held as of the Expiry Time by or on behalf of the Offeror, if any, representing at least 66²/3% of the then issued and outstanding SBT Units; (ii) all governmental or regulatory approvals (including those of any stock exchange or other securities regulatory authorities) that are necessary to complete the Offer and the Merger Transaction, including the listing on the TSX and NYSE Arca of the PSLV Units issuable pursuant to the Offer and the Merger Transaction, having been obtained or concluded on terms and conditions reasonably satisfactory to the Offeror; (iii) the Special Resolutions Power of Attorney having been validly granted in respect of at least 66²/3% of the then issued and outstanding SBT Units and the Special Resolutions having been validly passed; (iv) SBT and Sprott Physical Silver Trust not being prohibited by applicable Law, or their respective constating documents, from completing the Merger Transaction; and (v) the absence of any Material Adverse Change in relation to SBT.

Take-Up and Payment for Tendered SBT Units

If all the conditions of the Offer described in Section 4 of the Offer, "Conditions of the Offer", have been satisfied or waived by the Offeror at or prior to the Expiry Time, the Offeror will become obligated to take up Tendered SBT Units validly deposited under the Offer and not properly withdrawn promptly following the Expiry Time, but in no event later than ten days after the Expiry Time of the Offer; and will pay for SBT Units taken up as soon as practicable thereafter, but in any event not later than three business days after taking up the Tendered SBT Units.

By making a Merger Election, Merger Electing SBT Unitholders will deposit the Merger Elected SBT Units in the Offer and then will be deemed to have withdrawn such Merger Elected SBT Units from the Offer, effective at 4:59 p.m. (Toronto time) on the Expiry Date. Accordingly, if the Merger is completed, Merger Elected SBT Units will not be taken-up and paid for under the Offer, but such Merger Elected SBT Units will participate in the Merger and Merger Electing SBT Unitholders will receive PSLV Units upon the redemption of their SBT Units as part of the Merger Transaction. The deemed withdrawal will neither revoke the Special Resolutions Power of Attorney nor require the Depositary to return the Merger Elected SBT Units.

The Offeror's current intention is to complete the Merger (including the distribution of PSLV Units to SBT Unitholders upon the redemption of the outstanding SBT Units) immediately following and conditional on take-up of and payment for Tendered SBT Units under the Offer. This is intended to provide the most consistent treatment possible to all SBT Unitholders, whether they are exchanging SBT Units for PSLV Units under the Offer or as a result of the Merger.

Withdrawal of Deposited SBT Units

SBT Units deposited under the Offer may be withdrawn by or on behalf of the Depositing SBT Unitholder at any time before the SBT Units have been taken up by the Offeror under the Offer (provided, however, that if withdrawn after 4:58 p.m. (Toronto time) on the Expiry Date the Special Resolutions Power of Attorney granted in connection with such Deposited SBT Units, if applicable, will already have been used to pass the Special Resolutions) and in the other circumstances described in Section 8 of the Offer, "Withdrawal of Deposited SBT Units". Except as so indicated or as otherwise required or permitted by applicable Laws, deposits of SBT Units are irrevocable.

Additional Details of the Merger Transaction

Subject to the approval of the Special Resolutions, the Offeror intends to sign and deliver, on behalf of SBT, the Merger Agreement with Sprott Physical Silver Trust prior to the Expiry Time.

Pursuant to the Merger Agreement, and subject to the terms and conditions thereof, Sprott Physical Silver Trust would agree to acquire substantially all of the assets and assume all of the liabilities of SBT (other than the Administration Agreement) in return for such number of PSLV Units as is determined by the NAV to NAV Exchange Ratio based on the then outstanding SBT Units.

The closing of the transactions under the Merger Agreement would occur, subject to the terms and conditions of the Merger Agreement, on such date as is specified in writing by Sprott Physical Silver Trust, which is currently expected to occur immediately following and conditional on the take-up of and payment for Tendered SBT Units under the Offer. SBT would agree to then redeem all outstanding SBT Units and distribute the PSLV Units to the former holders of SBT Units on the same terms as under the Offer, namely on the basis of the NAV to NAV Exchange Ratio. Any PSLV Units received by the Offeror as a holder of SBT Units at such time would be transferred to Sprott Physical Silver Trust and be cancelled. Notwithstanding the foregoing, the Offeror may retain or reacquire one SBT Unit in its discretion to keep SBT in existence.

Certain Canadian Federal Income Tax Considerations

Disposition of SBT Units Pursuant to the Exchange Offer Election

In general, a disposition of SBT Units held as capital property by an Exchange Offer Electing SBT Unitholder in exchange for PSLV Units will give rise to a capital gain (or a capital loss) equal to the amount by which the proceeds of disposition of the Tendered SBT Units, net of any costs of disposition, exceed (or are less than) the adjusted cost base of the Tendered SBT Units to the Exchange Offer Electing SBT Unitholder immediately prior to the disposition. The proceeds of disposition of the Tendered SBT Units will generally be equal to the aggregate fair market value of the PSLV Units received in exchange therefor. The cost for tax purposes of the PSLV Units received in exchange for Tendered SBT Units will be equal to the fair market value of such PSLV Units. An Exchange Offer Electing SBT Unitholder who is not resident in Canada will not be subject to tax in respect of any capital gain realized on the disposition of Tendered SBT Units unless such SBT Units constitute "taxable Canadian property" of such SBT Unitholder for purposes of the Tax Act.

Transfer of SBT Assets to Sprott Physical Silver Trust Pursuant to the Merger

The Merger is expected to constitute a "qualifying exchange" as defined in section 132.2 of the Tax Act, thereby allowing substantially all of the assets of SBT to be transferred to Sprott Physical Silver Trust for proceeds of disposition equal to the tax cost of such assets. In such circumstances, there should be no taxable income to SBT arising from the transfer and, as a result there should be no tax liability to SBT Unitholders resulting from the transfer.

Disposition of SBT Units by SBT Unitholders Pursuant to the Merger

As noted above, the Merger is expected to constitute a "qualifying exchange" as defined in section 132.2 of the Tax Act. Accordingly, where a Merger Electing SBT Unitholder or a Non-Depositing SBT Unitholder disposes of SBT Units to SBT in exchange for PSLV Units on the redemption of SBT Units pursuant to the Merger, the SBT Unitholder's proceeds of disposition for the SBT Units disposed of, and the cost to the SBT Unitholder of the PSLV Units received in exchange therefor, will be deemed to be equal to the adjusted cost base to the SBT Unitholder of the SBT Units immediately prior to their disposition. For the purpose of determining the adjusted cost base of the PSLV Units acquired by a SBT Unitholder on such exchange, the cost of such PSLV Units will be determined by averaging their cost with the adjusted cost base of all other PSLV Units held as capital property by such SBT Unitholder immediately before the exchange.

SBT will not realize a gain or loss on the transfer of the PSLV Units to the SBT Unitholders on the redemption of SBT Units.

Certain United States Federal Income Tax Considerations

Disposition of SBT Units by SBT Unitholders Pursuant to the Exchange Offer Election and the Merger Transaction

An exchange of SBT Units for PSLV Units pursuant to the Exchange Offer Election or the Merger Transaction should be treated as a single transaction for U.S. federal income tax purposes that is intended to qualify as a Reorganization. Subject to the PFIC rules discussed in Section 21 of the Circular, "Certain United States Federal Income Tax Considerations", a U.S. Holder that exchanged SBT Units for PSLV Units pursuant to the Exchange Offer Election or the Merger Transaction generally would not recognize gain or loss on the exchange. A U.S. Holder's initial aggregate tax basis in the PSLV Units received would be equal to the

18

U.S. Holder's aggregate adjusted tax basis in the SBT Units exchanged, and a U.S. Holder's holding period in the PSLV Units received would include the U.S. Holder's holding period in the SBT Units exchanged.

Risk Factors

An investment in PSLV Units and the Offer and Merger Transaction are subject to certain risks. In assessing the Offer and the Merger Transaction, SBT Unitholders should carefully consider the risks described in Section 23 of the Circular, "Risk Factors".

Depositary

The Offeror has engaged Kingsdale Shareholder Services to act as the Depositary to receive deposits of certificates representing SBT Units and accompanying Letters of Transmittal deposited under the Offer at its offices in Toronto, Ontario, Canada specified in the Letter of Transmittal and to provide information to SBT Unitholders in connection with the Offer and Merger Transaction. The Depositary will also be responsible for giving certain notices, if required, and for making payment for all SBT Units purchased by the Offeror under the Offer and for all SBT Units to be redeemed as part of the Merger Transaction. The Depositary will also facilitate book-entry transfers of SBT Units. See Section 3 of the Offer, "Manner of Acceptance", and Section 27 of the Circular, "Depositary".

The Depositary will receive reasonable and customary compensation from the Offeror for its services in connection with the Offer and Merger Transaction and will be reimbursed for certain out-of-pocket expenses.

The accompanying Circular, which is incorporated into and forms part of the Offer, contains important information that should be read carefully before making a decision with respect to the Offer. Capitalized terms used in the Offer but not otherwise defined herein are defined in the accompanying Glossary. All currency amounts expressed herein, unless otherwise indicated, are expressed in United States dollars.

Subject to the terms and conditions of the Offer, the Offeror is offering to purchase all of the issued and outstanding SBT Units for consideration per SBT Unit of such number of PSLV Units as is determined on the basis of the NAV to NAV Exchange Ratio.

The Offer comprises the Exchange Offer Election and the Merger Election. SBT Unitholders that elect the Merger Election can exchange their SBT Units for PSLV Units based on the NAV to NAV Exchange Ratio on a tax-deferred basis for U.S. and Canadian income tax purposes. SBT Unitholders who wish to crystallize the realization of any gain (or loss) for Canadian income tax purposes may elect the Exchange Offer Election in order to exchange their SBT Units for PSLV Units based on the NAV to NAV Exchange Ratio and have the transaction treated as a taxable disposition for Canadian income tax purposes. The exchange of SBT Units under the Exchange Offer Election will only be treated as a taxable disposition for U.S. income tax purposes if the Merger does not occur and otherwise the exchange of SBT Units should be treated with the Merger as a tax deferred transaction for U.S. income tax purposes.

SBT Unitholders that elect the Merger Election can exchange their SBT Units for PSLV Units on a tax-deferred basis for U.S. and Canadian income tax purposes, so as to defer the realization of any gain (or loss) for U.S. or Canadian tax purposes.

The Offeror's current intention, subject to the applicable conditions, is to complete the Merger (including the distribution of PSLV Units to SBT Unitholders upon the redemption of the outstanding SBT Units) immediately following and conditional on take-up of and payment for Tendered SBT Units under the Offer. This is intended to provide the most consistent treatment possible to all SBT Unitholders, whether they are exchanging SBT Units for PSLV Units under the Offer or as a result of the Merger.

SBT Unitholders who deposit SBT Units and participate in the Offer will be required to either make: (i) the Exchange Offer Election, in which case such Tendered SBT Units would, subject to the satisfaction or waiver of the conditions to the Offer, be taken-up and paid for under the Offer; or (ii) the Merger Election, in which case such Merger Elected Units would, subject to the completion of the Merger Transaction, participate in the Merger Transaction.

If, for any reason, you deposit your SBT Units in the Offer but make no election (i.e. an Exchange Offer Election or a Merger Election), you will be deemed to have made a Merger Election in respect of such SBT Units and will be treated the same as a Merger Electing SBT Unitholder.

The number of PSLV Units to be distributed to each SBT Unitholder under the Offer and the Merger Transaction will be determined on a Net Asset Value to Net Asset Value basis based on the NAV to NAV Exchange Ratio. By way of example, based on the Net Asset Value per unit of Sprott Physical Silver Trust (U.S.$6.66) and SBT (U.S.$10.00) as of May 22, 2015 (calculated in a manner consistent with the NAV to NAV Exchange Ratio), a SBT Unitholder would receive 1.5009 PSLV Units for each SBT Unit held.

20

Time is of the essence. Send in your SBT Units with a completed YELLOW Letter of Transmittal to the Depositary or call your broker now to deposit.

Based on the closing price of PSLV Units on NYSE Arca on May 22, 2015 and the Bank of Canada noon rate of exchange for the U.S. dollar on May 22, 2015, the consideration offered pursuant to the Offer and the Merger Transaction had a value of approximately U.S.$9.67 per SBT Unit (determined in a manner consistent with the NAV to NAV Exchange Ratio). Based on the closing prices of the SBT Units and the PSLV Units on the TSX (SBT.UN) and NYSE Arca, respectively, on April 22, 2015, being the last trading day prior to the public announcement of the Manager's intention to commence the Offer, the SBT Units were trading at a -10.3% discount to NAV while the PSLV Units were trading at a 1.07% PREMIUM to NAV. These spreads have been relatively consistent over a prolonged period of time.

Since the Manager announced its intention to commence the Offer on April 23, 2015, the discount to NAV at which the SBT Units have traded has narrowed by approximately 51%. The Offer unlocks approximately U.S.$4.95 million in SBT Unitholder value (based on the closing prices of the SBT Units and the PSLV Units on the TSX (SBT.UN) and NYSE Arca, respectively, on April 22, 2015 and the Bank of Canada noon rate of exchange for the U.S. dollar on May 22, 2015).

The Offeror and the Manager believe that investors in physical bullion vehicles want a secure, convenient and exchange-traded alternative to actually holding physical silver that has reasonable redemption features, trades at or around the market value of the bullion it holds, and is appropriately marketed to generate buying interest and enhanced trading liquidity.

The Manager and the Offeror believe that SBT units persistently trade at a discount to NAV because SBT management does not reinvest the fees it collects in marketing the product. Additionally, SBT features a punitive redemption feature that forces unitholders to redeem their units for less than market value. Unlike Sprott Physical Silver Trust, SBT does not allow its unitholders to redeem for physical silver.

By supporting the Offer, SBT unitholders will have an opportunity to move into an investment vehicle that has consistently outperformed SBT, while also benefitting from a significantly larger asset base and increased liquidity.

The Offer is being made only for SBT Units and is not being made for any other securities.

The obligation of the Offeror to take up and pay for SBT Units pursuant to the Offer is subject to certain conditions. See Section 4 of the Offer, "Conditions of the Offer".

SBT Unitholders should contact the Depositary and Information Agent, their investment advisor, stockbroker, bank, trust company or other nominee for assistance in participating in the Offer and in depositing their SBT Units with the Depositary.

The Offer is open for deposits of SBT Units during the period commencing on May 27, 2015 and ending at 5:00 p.m. (Toronto time) on July 6, 2015, or such later time or times and date or dates to which the Offer may be extended from time to time by the Offeror, in accordance with Section 5 of the Offer, "Extension, Variation or Change of the Offer", unless the Offer is withdrawn by the Offeror. Any decision to extend the Offer, including for how long, will be made prior to the Expiry Time. The Expiry Time may be subject to multiple extensions.

previously scheduled expiration of the offer and, if required by applicable Law, the Offeror will mail you a copy of the notice of variation.

SBT Unitholders may participate in the Offer by delivering to the Depositary at its office in Toronto, Ontario, Canada specified in the Letter of Transmittal (printed on YELLOW paper) accompanying the Offer, so as to be received at or prior to the Expiry Time:

In certain cases, the signatures on the Letter of Transmittal must be guaranteed by an Eligible Institution. See Section 3 of the Offer, "Manner of Acceptance — Letter of Transmittal Signature Guarantees" below and the instructions set out in the Letter of Transmittal in order to determine if the signatures on your Letter of Transmittal must be guaranteed by an Eligible Institution.

SBT Unitholders will be deemed to participate in the Offer, and their SBT Units will only be deposited if the Depositary has actually received these documents at its office in Toronto, Ontario, Canada specified in the Letter of Transmittal at or prior to the Expiry Time. Alternatively, SBT Units may be deposited under the Offer in compliance with the procedures for book-entry transfers set out below under the heading Section 3 of the Offer, "Manner of Acceptance — Acceptance by Book-Entry Transfer".

In all other cases, all signatures on the Letter of Transmittal must be guaranteed by an Eligible Institution.

If a certificate representing SBT Units is registered in the name of a person other than the signatory of a Letter of Transmittal or if the PSLV Units payable are to be delivered to a person other than the registered holder, the certificate must be endorsed or accompanied by an appropriate unit transfer power of attorney, in either case, signed exactly as the name of the registered holder appears on the certificate with the signature on the certificate or power of attorney guaranteed by an Eligible Institution.

CDS will be issuing instructions to their participants as to the method of depositing SBT Units in the Offer.

SBT Unitholders may also participate in the Offer by following the procedures for a book-entry transfer established by CDS provided that a Book-Entry Confirmation through CDSX is received by the Depositary at its office in Toronto, Ontario, Canada specified in the Letter of Transmittal at or prior to the Expiry Time. The Depositary has established an account at CDS for the purpose of the Offer. Any financial institution that is a participant in CDS may cause CDS to make a book-entry transfer of a SBT Unitholder's SBT Units into the Depositary's account in accordance with CDS' procedures for such transfer. Delivery of SBT Units to the Depositary by means of a book-entry transfer will constitute a valid deposit of such SBT Units under the Offer. SBT Unitholders, through their respective CDS participants who utilize CDSX to deposit to the Offer through a book-entry transfer of their holdings into the Depositary's account with CDS, shall be deemed to have

22

completed and delivered a Letter of Transmittal and to be bound by the terms thereof and therefore such instructions received by the Depositary are considered a valid deposit of SBT Units in accordance with the terms of the Offer.

In all cases, payment for Deposited SBT Units deposited and taken up by the Offeror will be made only after timely receipt by the Depositary of: (i) certificates or, in the case of a book-entry transfer to the Depositary, a Book-Entry Confirmation for the SBT Units, as applicable; (ii) a Letter of Transmittal, properly completed and duly executed (or a manually executed facsimile thereof), covering such SBT Units with the signatures guaranteed, if required, in accordance with the instructions set out in the Letter of Transmittal (or, in the case of a book-entry transfer to the Depositary through CDS, a Book-Entry Confirmation for the SBT Units), and (iii) all other required documents.

If any certificate representing SBT Units has been lost, stolen or destroyed, the registered holder of such SBT Units should complete the Letter of Transmittal as fully as possible and forward it, together with an affidavit regarding the loss, theft or destruction, to the Depositary. The Depositary will assist in making arrangements for the necessary affidavit (which will include a bonding requirement) for payment in accordance with the Offer. Further details are set out in the Letter of Transmittal. The registered holder will be required to indemnify the Offeror, the Manager, SAM Silver Bid GP, SAM GP Inc., Sprott Physical Silver Trust, SBT and the Depositary against any claim that may be made against the Offeror, the Manager, SAM Silver Bid GP, SAM GP Inc., Sprott Physical Silver Trust, SBT or the Depositary with respect to such lost, stolen or destroyed certificate.

The method of delivery of certificates representing SBT Units, the Letter of Transmittal and all other required documents is at the option and risk of the person depositing those documents. The Offeror recommends that such documents be delivered by hand to the Depositary and a receipt obtained or, if mailed, that registered mail, with return receipt requested, be used and that proper insurance be obtained. It is suggested that any such mailing be made sufficiently in advance of the Expiry Time to permit delivery to the Depositary before the Expiry Time. Delivery will only be effective upon actual physical receipt by the Depositary.

Beneficial SBT Unitholders should contact their investment advisor, stockbroker, bank, trust company or other nominee for assistance if they wish to participate in the Offer in order to take the necessary steps to be able to deposit such SBT Units under the Offer. Nominees will likely establish depositing cut-off times that are up to 48 hours prior to the Expiry Time. SBT Unitholders must instruct their investment advisor, stockbroker, bank, trust company or other nominee promptly if they wish to deposit.

All questions as to the validity, form, eligibility (including timely receipt) and acceptance of any SBT Units deposited under the Offer will be determined by the Offeror in its sole discretion. Depositing SBT Unitholders agree that such determination shall be final and binding. The Offeror reserves the right to reject any and all deposits that it determines not to be in proper form or that may be unlawful to accept under the Laws of any applicable jurisdiction. The Offeror reserves the right to waive any defects or irregularities in the deposit of any SBT Units. There shall be no duty or obligation of the Offeror, the Depositary or any other person to give notice of any defects or irregularities in any deposit and no liability shall be incurred by any of them for failure to give any such notice. The Offeror's interpretation of the terms and conditions of the Offer, the Circular and the Letter of Transmittal will be final and binding.

The Offeror reserves the right to permit participation in the Offer in a manner other than that set out in this Section 3.

Under no circumstance will interest accrue or any amount be paid by the Offeror or the Depositary by reason of any delay in making payments for SBT Units to any person on account of SBT Units accepted for payment under the Offer or redeemed as part of the Merger Transaction.

Subject to the terms and conditions of the Offer and subject, in particular, to SBT Units being validly withdrawn by or on behalf of a Depositing SBT Unitholder, and except as provided below, by accepting the Offer pursuant to the procedures set forth herein, a SBT Unitholder deposits, sells, assigns and transfers to the Offeror all right, title and interest in and to the SBT Units covered by the Letter of Transmittal or book-entry transfer and in and to all rights and benefits arising from such SBT Units, including any and all distributions, payments, securities, property or other interests that may be declared, paid, accrued, issued, distributed, made or transferred on or in respect of such SBT Units or any of them after May 27, 2015 (being the date the Offer is open for acceptance), including any distributions or payments on such distributions, payments, securities, property or other interests and any securities, property or other interests for which such SBT Units may be exercised, exchanged or converted (collectively, the "Distributions")

The Special Resolutions Power of Attorney will only be used and relied upon if the Offeror intends to proceed with the take up of and payment for Tendered SBT Units.

In order not to provide the Special Resolutions Power of Attorney as described above, withdrawals of Deposited SBT Units must be effected prior to 4:58 p.m. (Toronto time) on the Expiry Date. A notice of withdrawal of such Deposited SBT Units must actually be received by the Depositary prior to 4:58 p.m. (Toronto time) on the Expiry Date in a manner such that the Depositary has a written or printed copy of such notice of withdrawal.

A Depositing SBT Unitholder's broker or other nominee may set deadlines for the withdrawal of Deposited SBT Units that are earlier than those specified above and Electing SBT Unitholders should contact their broker or other nominee for further details or assistance.

Upon the appointment referred to in (a) above, all prior proxies and other authorizations (including, without limitation, all appointments of any agent, attorney or attorney-in-fact) or consents given by the Depositing SBT Unitholder with respect to such Depositing SBT Unitholder's Deposited SBT Units will be revoked and no subsequent proxies or other authorizations or consents may be given by such person with respect thereto (other than the Special Resolutions Power of Attorney in (b) above and the power in (c) above).

A SBT Unitholder accepting the Offer covenants under the terms of the Letter of Transmittal or book-entry transfer to execute, upon request of the Offeror, any additional documents, transfers and other assurances as may be necessary or desirable to complete the sale, assignment and transfer of the Purchased Securities or Distributions to the Offeror, the Merger Transaction or the implementation of the Offeror's plans as described in Section 5 of the Circular, "Purpose of the Offer and the Offeror's Plans for SBT" and acknowledges that all authority therein conferred or agreed to be conferred may be exercised during any subsequent legal incapacity of such holder and shall, to the extent permitted by Law, survive the death or incapacity, bankruptcy or insolvency of the SBT Unitholder and all obligations of the SBT Unitholder therein shall be binding upon the heirs, executors, administrators, attorneys, personal representatives, successors and assigns of such SBT Unitholder.

Participation in the Offer pursuant to the procedures set out above constitutes a binding agreement between a Depositing SBT Unitholder and the Offeror in accordance with the terms and conditions of the Offer and the Letter of Transmittal. Such agreements include a representation and warranty by the Depositing SBT Unitholder that: (i) the person signing the Letter of Transmittal or on whose behalf a book-entry transfer is made has full power and authority to deposit, sell, assign and transfer the Deposited SBT Units and all rights

25

and benefits arising from such Deposited SBT Units; (ii) the person signing the Letter of Transmittal or on whose behalf a book-entry transfer is made owns the Deposited SBT Units deposited under the Offer, (iii) the Deposited SBT Units have not been sold, assigned or transferred, nor has any agreement been entered into to sell, assign or transfer any of the Deposited SBT Units, to any other person; (iv) the deposit of the Deposited SBT Units complies with applicable Laws, (v) the person signing the Letter of Transmittal or on whose behalf a book-entry transfer is made has full power and authority to grant Special Resolutions Power of Attorney and the powers and proxies described under (a) and (c) under "Power of Attorney" above; and (vi) in the case of Tendered SBT Units, the Deposited SBT Units are taken up and paid for by the Offeror, the Offeror will acquire good title thereto, free and clear of all liens, restrictions, charges, encumbrances, claims and rights of others.

The Offeror reserves the right to permit the Offer to be accepted in a manner other than that set forth in this Section 3.

Notwithstanding any other provision of the Offer, and subject to applicable Laws, the Offeror shall have the right to withdraw or terminate the Offer and not take up and pay for any SBT Units deposited under the Offer, and/or to extend the period of time during which the Offer is open for acceptance and postpone taking up and paying for any SBT Units deposited under the Offer, and/or to amend the Offer, unless all of the following conditions are satisfied or waived by the Offeror (in its sole discretion) at or before the Expiry Time:

27

The foregoing conditions are for the exclusive benefit of the Offeror and may be asserted by the Offeror at any time, regardless of the circumstances giving rise to such assertion, including any action or inaction by the Offeror. Each of the foregoing conditions is independent of and in addition to each other such condition. The Offeror may waive any of the foregoing conditions with respect to the Offer in its reasonable discretion, in whole or in part, at any time and from time to time, both before and after the Expiry Time, without prejudice to any other rights that the Offeror may have. The failure by the Offeror at any time to exercise or assert any of the foregoing rights will not be deemed a waiver of any such right and each such right will be deemed an ongoing right that may be asserted at any time and from time to time by the Offeror.

Any waiver of a condition or the withdrawal of the Offer will be effective upon written notice, or other communication confirmed in writing, by the Offeror to that effect to the Depositary at its principal office in Toronto, Ontario, Canada. The Offeror, after giving any such notice, will make a public announcement of such waiver or withdrawal, and will cause the Depositary, if required by Law, as soon as practicable thereafter to

28

Time is of the essence. Send in your SBT Units with a completed YELLOW Letter of Transmittal to the Depositary or call your broker now to deposit.

notify the SBT Unitholders, in the manner set forth in Section 9 of the Offer, "Notices and Delivery". If the Offer is withdrawn, the Offeror will not be obligated to take up or pay for any SBT Units deposited under the Offer or proceed with the Merger Transaction and the Depositary will promptly return all documents tendered to the Depositary under the Offer including certificates representing deposited SBT Units, Letters of Transmittal and related documents to the parties by whom they were deposited. See Section 7 of the Offer, "Return of Deposited SBT Units".

Any determination by the Offeror concerning any events or other matters described in this Section 4 will be final and binding upon all persons for purposes of the Offer.

The Offer is open for deposits of SBT Units (making the Exchange Offer Election or the Merger Election) at the place specified in the Letter of Transmittal and in the manner specified under "Manner of Acceptance" in Section 3 of the Offer, above, until, but not after, 5:00 p.m. (Toronto time) on July 6, 2015, subject to extension or variation in the Offeror's sole discretion, unless the Offer is withdrawn by the Offeror.

Subject to the limitations hereafter described, the Offeror reserves the right, in its sole discretion, at any time and from time to time while the Offer is open for acceptance (or at any other time if permitted by applicable Laws), to extend the Expiry Time or to vary the terms of the Offer by giving written notice (or other communication subsequently confirmed in writing, provided that such confirmation is not a condition of the effectiveness of the notice) of such extension or variation to the Depositary at its principal office in Toronto, Ontario, Canada and by causing the Depositary as soon as practicable thereafter to communicate such notice in the manner set forth under "Notices and Delivery" in Section 9 of the Offer, to any SBT Unitholders whose Deposited SBT Units have not been taken up prior to the extension or variation. The Offeror shall, as soon as possible after giving notice of an extension or variation to the Depositary, make a public announcement of the extension or variation. In addition, the Offeror will provide a copy of such notice to the TSX and the applicable Securities Regulatory Authorities. Any notice of extension or variation will be deemed to have been given and the Offer deemed to be extended or varied in accordance with such notice effective on the day on which it is delivered or otherwise communicated in writing to the Depositary at its principal office in Toronto, Ontario, Canada.

Unless otherwise permitted or required by Law and subject to abridgement or elimination of that period pursuant to such orders as may be granted by the applicable Securities Regulatory Authorities, where the terms of the Offer are varied (including if the Offeror makes a material change in the information to the Offer in Section 4 or waives a condition of the Offer), the Offer will not expire before ten days after the date of the notice of such variation or such longer time as is required by applicable law or is sufficient to allow you to consider the amended terms of the Offer. If, prior to the Expiry Time, the Offeror changes the consideration to be paid for SBT Units in the Offer, the percentage of outstanding units of SBT Units being sought in the Offer, or makes a similarly significant change to the Offer, and if the Offer is scheduled to expire at any time before the expiration of a period of ten business days from and including the date that notice of such change is first announced, the Offer will be extended at least until the expiration of that period of ten business days. During any extension or in the event of any variation of the Offer or change in information, all Deposited SBT Units not taken-up or withdrawn will remain subject to the Offer and may be accepted for purchase by the Offeror in accordance with the terms hereof, subject to Section 8 of the Offer, "Withdrawal of Deposited SBT Units". An extension of the Expiry Time, a variation of the Offer or a change in information does not, unless expressly stated, constitute a waiver by the Offeror of its rights under "Conditions of the Offer" in Section 4 of the Offer.

If, before the Expiry Time or after the Expiry Time but before the expiry of all rights of withdrawal with respect to the Offer, a change occurs in the information contained in the Offer or the Circular, as amended from time to time, that would reasonably be expected to affect the decision of a SBT Unitholder to accept or reject the Offer (other than a change that is not within the control of the Offeror or of an affiliate of the Offeror), the Offeror will provide written notice of such change to the Depositary at its principal office in Toronto, Ontario, Canada, and will, at the expense of the Offeror, cause the Depositary to provide as soon as practicable thereafter a copy of such notice in the manner set forth under "Notices and Delivery" in Section 9 of the Offer, to all SBT Unitholders whose Deposited SBT Units have not been taken up under the Offer at the date of the occurrence of the change, if required by applicable Laws. As soon as practicable after giving notice of a change in

29

information to the Depositary, the Offeror will make a public announcement of the change in information and provide a copy of the notice thereof to the TSX and the applicable Securities Regulatory Authorities. Any notice of change in information will be deemed to have been given and to be effective on the day on which it is delivered or otherwise communicated to the Depositary at its principal office in Toronto, Ontario, Canada.

Notwithstanding the foregoing, but subject to applicable Laws, the Offer may not be extended by the Offeror if all of the terms and conditions of the Offer, except those waived by the Offeror, have been fulfilled or complied with, unless the Offeror first takes up all Deposited SBT Units not withdrawn. Merger Electing SBT Unitholders will be deemed to have withdrawn their Merger Elected SBT Units prior to the Expiry Time. The deemed withdrawal will neither revoke the Special Resolutions Power of Attorney nor require the Depositary to return the Merger Elected SBT Units.

If, prior to the Expiry Time, the consideration being offered for the SBT Units under the Offer is increased: (i) the increased consideration will be paid to all Exchange Offer Electing SBT Unitholders whose Tendered SBT Units are taken up under the Offer, whether or not taken up before or after such variation; and (ii) the increased consideration will be received by SBT Unitholders whose SBT Units are redeemed for PSLV units pursuant to the Merger Transaction.

Upon the terms and subject to the conditions of the Offer (including the conditions specified in Section 4 of the Offer, "Conditions of the Offer"), the Offeror will take up Tendered SBT Units validly deposited under the Offer and not properly withdrawn promptly following the Expiry Time but in no event later than ten days after the Expiry Time and will pay for SBT Units so taken up as soon as practicable thereafter, but in any event not later than three business days after taking up the Tendered SBT Units. The Offeror will be deemed to have taken up and accepted for payment Tendered SBT Units validly deposited and not properly withdrawn pursuant to the Offer if, as and when the Offeror gives written notice, or other communication confirmed in writing, to the Depositary at its offices in Toronto, Ontario, Canada to that effect.

Subject to applicable Law, the Offeror expressly reserves the right, in its sole discretion, at any time and from time to time, to delay taking up and paying for any SBT Units or to terminate the Offer and not take up or pay for any SBT Units pursuant to the Offer if any condition specified in Section 4 of the Offer, "Conditions of the Offer", is not satisfied or waived by the Offeror, by giving written notice thereof, or other communication confirmed in writing, to the Depositary at its principal office in Toronto, Ontario, Canada. The Offeror also expressly reserves the right, in its sole discretion and notwithstanding any other condition of the Offer, to delay taking up and paying for SBT Units in order to comply, in whole or in part, with any applicable Law. The Offeror's current intention is to complete the Merger Transaction immediately following and conditional on take-up of and payment for Tendered SBT Units under the Offer. Accordingly, a delay in taking up and paying for any SBT Units may delay or impede the completion of the Merger Transaction.

The Offeror will pay for Tendered SBT Units validly deposited under the Offer and not withdrawn by providing the Depositary with sufficient PSLV Units for transmittal to Exchange Offer Electing SBT Unitholders. Under no circumstances will interest accrue or any amount be paid by the Offeror or the Depositary to persons depositing Tendered SBT Units on the purchase price of SBT Units purchased by the Offeror, regardless of any delay in making such deliveries.

The Depositary will act as the agent of persons who have deposited: (i) Tendered SBT Units in acceptance of the Offer for the purposes of receiving payment from the Offeror and transmitting such payment to such persons, and receipt of payment by the Depositary will be deemed to constitute receipt of payment by persons depositing Tendered SBT Units under the Offer; and (ii) Merger Elected SBT Units for the purposes of receiving the PSLV Units to be received by such Merger Electing SBT Unitholder on the redemption of such Merger Elected SBT Units pursuant to the Merger Transaction.

Settlement with each Exchange Offer Electing SBT Unitholder who has deposited (and not properly withdrawn) Tendered SBT Units under the Offer and, if the Merger Transaction is completed, each Merger Electing SBT Unitholder and Non-Depositing SBT Unitholder, will be made by the Depositary delivering or causing to be delivered certificates representing PSLV Units, in the amounts to which the SBT Unitholder is entitled pursuant to the Offer or the Merger Transaction, as applicable. Unless otherwise directed by the Letter

30

Time is of the essence. Send in your SBT Units with a completed YELLOW Letter of Transmittal to the Depositary or call your broker now to deposit.

of Transmittal, the certificates will be issued in the name of the registered holder of the SBT Units so deposited. Unless the person depositing the SBT Units instructs the Depositary to hold the certificates for pick-up by checking the appropriate box in the Letter of Transmittal, the certificates will be forwarded by first class mail to such person at the address specified in the Letter of Transmittal. If no such address is specified, the certificates will be sent to the address of the registered holder as shown on the securities register maintained by or on behalf of SBT. Pursuant to applicable Laws, the Offeror may, in certain circumstances, be required to make withholdings from the amount otherwise payable to a SBT Unitholder.

Exchange Offer Electing SBT Unitholders will not be required to pay any fee or commission if they accept the Offer by depositing their Tendered SBT Units directly with the Depositary. An investment advisor, stockbroker, bank, trust company or other nominee through whom an Exchange Offer Electing SBT Unitholder holds SBT Units may charge a fee to deposit any such SBT Units on behalf of the Exchange Offer Electing SBT Unitholder. SBT Unitholders should consult such nominee to determine whether any charges will apply.

Any Deposited SBT Units either not: (i) taken up and paid for by the Offeror pursuant to the terms and conditions of the Offer; or (ii) redeemed pursuant to the Merger Transaction, for any reason, will be returned to the Depositing SBT Unitholder promptly following the Expiry Time or the termination or withdrawal of the Offer, by either returning the deposited certificates representing the Deposited SBT Units not purchased or redeemed (and other relevant documents) or, in the case of Deposited SBT Units deposited by book-entry transfer pursuant to the procedures set forth under Section 3 of the Offer, "Manner of Acceptance — Acceptance by Book-Entry Transfer", such Deposited SBT Units will be credited to the Depositing SBT Unitholder's participant's account maintained by CDS. Certificates (and any other relevant documents) will be forwarded by first-class mail in the name of and to the address specified by the Depositing SBT Unitholder in the Letter of Transmittal or, if such name or address is not so specified, in such name and to such address as shown on the unit register maintained by SBT or its transfer agent, promptly after the termination of the Offer.

Except as otherwise stated in this Section 8 (including if the Merger Election is made in respect of Deposited SBT Units) or as otherwise required by applicable Laws, all deposits of SBT Units pursuant to the Offer are irrevocable. Unless otherwise required or permitted by applicable Laws, any SBT Units deposited under the Offer may be withdrawn by or on behalf of the Depositing SBT Unitholder:

31

Time is of the essence. Send in your SBT Units with a completed YELLOW Letter of Transmittal to the Depositary or call your broker now to deposit.

Withdrawals of Deposited SBT Units must be effected by notice of withdrawal made by or on behalf of the Depositing SBT Unitholder in writing and must actually be received by the Depositary at the place of deposit before such Deposited SBT Units are taken up and paid for. Notice of withdrawal: (i) must be made by a method, including facsimile transmission, that provides the Depositary with a written or printed copy, (ii) must be signed by or on behalf of the person who signed the Letter of Transmittal accompanying the Deposited SBT Units that are to be withdrawn, (iii) must specify such person's name, the number of Deposited SBT Units to be withdrawn, the name of the registered holder and the certificate number shown on each certificate representing the Deposited SBT Units to be withdrawn, and (iv) must be actually received by the Depositary at the place of deposit of the applicable Deposited SBT Units. Any signature in a notice of withdrawal must be guaranteed by an Eligible Institution in the same manner as in a Letter of Transmittal (as described in the instructions set out therein), except in the case of SBT Units deposited for the account of an Eligible Institution.

Alternatively, if Deposited SBT Units have been deposited pursuant to the procedures for book-entry transfer, as set out under Section 3 of the Offer, "Manner of Acceptance — Acceptance by Book-Entry Transfer", the Depositing SBT Unitholder must contact their CDS participant and instruct them to withdraw the Deposited SBT Units in accordance with the CDS procedures to effect a withdrawal of a book-entry transfer.

All questions as to the validity (including timely receipt) and form of notices of withdrawal will be determined by the Offeror, in its sole discretion, and such determination will be final and binding. There will be no obligation on the Depositary, the Offeror or any other person to provide notice of any defect or irregularity in any notice of withdrawal and no such person will incur any liability for failure to give such notice.

Wherever the Offer calls for documents to be delivered by or on behalf of SBT Unitholders to a particular office of the Depository, those documents will not be considered delivered unless and until they have been physically received at the particular office at the address listed in the Letter of Transmittal. Withdrawals may not be rescinded and any Deposited SBT Units properly withdrawn will be deemed not validly deposited for the purposes of the Offer but may be re-deposited at any subsequent time prior to the Expiry Time by following any of the procedures described in Section 3 of the Offer, "Manner of Acceptance".

If the Offeror extends the period of time during which the Offer is open, is delayed in taking up or paying for Tendered SBT Units or is unable to take up or pay for Tendered SBT Units for any reason, then, without prejudice to the Offeror's other rights, Deposited SBT Units may, subject to applicable Laws, be retained by the Depositary on behalf of the Offeror and such Deposited SBT Units may not be withdrawn except to the extent that Depositing SBT Unitholders are entitled to withdrawal rights as set forth in this Section 8 or pursuant to applicable Laws.

A withdrawal of Deposited SBT Units can only be accomplished in accordance with the foregoing procedures. The withdrawal will take effect only upon actual receipt by the Depositary of the properly completed and executed written notice of withdrawal or a withdrawal notice received from CDS, as applicable.

Notwithstanding the foregoing, by making a Merger Election, Merger Electing SBT Unitholders will deposit the Merger Elected SBT Units in the Offer and then will be deemed to have withdrawn such Merger Elected SBT Units from the Offer, effective at 4:59 p.m. (Toronto time) on the Expiry Date. Accordingly, if the Merger is completed, Merger Elected SBT Units will not be taken-up and paid for under the Offer but such Merger Elected SBT Units will participate in the Merger and Merger Electing SBT Unitholders will receive PSLV Units upon the redemption of their SBT Units as part of the Merger Transaction. The deemed withdrawal will neither revoke the Special Resolutions Power of Attorney nor require the Depositary to return the Merger Elected SBT Units.

In addition to the foregoing rights of withdrawal, SBT Unitholders in certain provinces and territories of Canada are entitled to statutory rights of rescission or to damages, or both, in certain circumstances. See Section 25 of the Circular, "Statutory Rights".

Without limiting any other lawful means of giving notice, any notice to be given by the Offeror or the Depositary pursuant to the Offer will be deemed to have been properly given if it is mailed by first class mail, postage prepaid, to the registered SBT Unitholders at their addresses as shown on the registers maintained by or

32

on behalf of SBT and will be deemed to have been received on the first business day following the date of mailing. For this purpose, "business day" means any day other than a Saturday or Sunday or statutory holiday in the City of Toronto. These provisions apply notwithstanding any accidental omission to give notice to any one or more SBT Unitholders and notwithstanding any interruption of mail service in any relevant jurisdiction following mailing. In the event of any interruption of mail service following mailing, the Offeror intends to make reasonable efforts to disseminate the notice by other means, such as publication.

Except as otherwise required or permitted by applicable Law, if post offices in Canada are not open for the deposit of mail, any notice that the Offeror or the Depositary may give or cause to be given to SBT Unitholders under the Offer will be deemed to have been properly given and to have been received by SBT Unitholders if: (i) it is given to the TSX and NYSE Arca for dissemination through their respective facilities, (ii) it is published once in the National Edition of The Globe and Mail or The National Post, together with The Wall Street Journal or The New York Times, and in La Presse in Québec or (iii) it is given to Marketwired and the Dow Jones News Service for dissemination through their respective facilities.

The Offer and Circular and accompanying Letter of Transmittal will be mailed to registered SBT Unitholders by first class mail, postage prepaid, or made available in such other manner as is permitted by applicable Laws and the Offeror will use its reasonable efforts to furnish such documents to investment advisors, stockbrokers, banks, trust companies, or other nominees whose names appear on the registers maintained by or on behalf of SBT in respect of the SBT Units or, if security position listings are available, who are listed as participants in a clearing agency's security position listing, for subsequent transmittal to the beneficial owners of SBT Units where such listings are received.

These SBT Unitholder materials are being sent to both registered and non-registered owners of securities of SBT. If you are a non-registered owner, and the Offeror or its agent has sent these materials directly to you, the Offeror believes your name and address and information about your holdings of securities of SBT have been obtained in accordance with applicable regulatory requirements from the nominee holding such securities on your behalf.

Wherever the Offer calls for documents to be delivered to the Depositary, such documents will not be considered delivered unless and until they have been physically received by the Depositary at its offices in Toronto, Ontario, Canada specified in the Letter of Transmittal. Wherever the Offer calls for documents to be delivered by or on behalf of SBT Unitholders to a particular office of the Depositary, those documents will not be considered delivered unless and until they have been physically received at the particular office at the address listed in the Letter of Transmittal.

Notwithstanding the provisions of the Offer and Circular and the Letter of Transmittal, certificates and any other relevant documents will not be mailed if the Offeror determines that delivery thereof by mail may be delayed. Persons entitled to certificates or any other relevant documents which are not mailed for the foregoing reason may take delivery thereof at the office of the Depositary to which the deposited certificates for SBT Units were delivered until such time as the Offeror has determined that delivery by mail will no longer be delayed. The Offeror will provide notice of any such determination not to mail made under this Section 10 as soon as reasonably practicable after the making of such determination and in accordance with Section 9 of the Offer, "Notices and Delivery".

See Section 5 of the Offer, "Extension, Variation or Change of the Offer".

SBT Units and any Distributions acquired under the Offer shall be transferred by the SBT Unitholders and acquired by the Offeror free and clear of all liens, restrictions, charges, encumbrances, claims and equities and together with all rights and benefits arising therefrom, including, the right to any and all distributions, payments, securities, property, rights, assets or other interests which may be accrued, declared, paid, issued, distributed, made or transferred on or after the date of the Offer on or in respect of the SBT Units, whether or not separated from the SBT Units.

The declaration or payment of any such distribution may have tax consequences not described in Section 20 of the Circular, "Certain Canadian Federal Income Tax Considerations" or in Section 21 of the Circular, "Certain United States Federal Income Tax Considerations". SBT Unitholders should consult their own tax advisors in respect of any such distribution.

If SBT Unitholders representing more than 66²/3% of the then issued and outstanding SBT Units deposit their SBT Units in the Offer (whether making the Exchange Offer Election or the Merger Election) prior to 4:58 p.m. on the Expiry Date, then the Special Resolutions will be approved.

The prohibition continues from the time of the public announcement of the offer until the expiration of the offer period, including extensions thereof.

Although the Offeror has no present intention to sell SBT Units taken up under the Offer, it reserves the right to make or to enter into an arrangement, commitment or understanding at or prior to the Expiry Time to sell any of such SBT Units after the Expiry Time.

Sprott Physical Silver Trust was established on June 30, 2010 under the laws of the Province of Ontario, Canada, pursuant to the PSLV Trust Agreement. Pursuant to the PSLV Trust Agreement and the PSLV Management Agreement, the Manager acts as the manager of Sprott Physical Silver Trust. The Manager initiated the creation and the organization of Sprott Physical Silver Trust and, accordingly, may be considered a promoter or sponsor of Sprott Physical Silver Trust under applicable securities laws. See Section 31 of the Circular, "Promoter".

As at March 31, 2015, the Manager, together with its affiliates and related entities, had assets under management totaling Cdn.$7.8 billion and provided management and investment advisory services to many entities, including private investment funds, the Sprott Mutual Funds and the Sprott discretionary managed accounts, and management of certain companies through its subsidiary, Sprott Consulting LP. The Manager also acts as manager for the Sprott Silver Bullion Fund, a Canadian public mutual fund that invests in physical silver bullion.

Sprott Physical Silver Trust is a reporting issuer or the equivalent in all the provinces and territories of Canada and files its continuous disclosure documents with the relevant Canadian securities regulatory authorities. Such documents are available on SEDAR at www.sedar.com. Sprott Physical Silver Trust is also an SEC registrant and accordingly files with or furnishes to the SEC certain documents. Such documents are

Sprott Physical Silver Trust was created to invest and hold substantially all of its assets in physical silver bullion. Many investors are unwilling to invest directly in physical silver bullion due to inconveniences such as transaction, handling, storage, insurance and other costs that are typical of a direct investment in physical silver bullion. Sprott Physical Silver Trust seeks to provide a secure, convenient and exchange-traded investment alternative for investors interested in holding physical silver bullion without the inconvenience that is typical of a direct investment in physical silver bullion. Sprott Physical Silver Trust invests primarily in long-term holdings of unencumbered, fully allocated, physical silver bullion and will not speculate with regard to short-term changes in silver prices.

The Manager is responsible for the day-to-day business and administration of Sprott Physical Silver Trust, including management of Sprott Physical Silver Trust's portfolio and all clerical, administrative and operational services.

RBC Investor Services Trust ("RBC Investor Services"), a trust company organized under the federal laws of Canada, is the trustee of Sprott Physical Silver Trust (in its capacity as trustee, the "PSLV Trustee"). The PSLV Trustee holds title to Sprott Physical Silver Trust's assets and has, together with the Manager, exclusive authority over the assets and affairs of Sprott Physical Silver Trust. The PSLV Trustee has a fiduciary responsibility to act in the best interest of the PSLV Unitholders.

The PSLV Trustee's office is located at 155 Wellington Street West, Street Level, Toronto, Ontario, Canada M5V 3L3.

Sprott Physical Silver Trust employs two custodians. The Royal Canadian Mint (the "Mint") acts as custodian for Sprott Physical Silver Trust's physical silver bullion pursuant to a silver storage agreement between the Manager, for and on behalf of Sprott Physical Silver Trust, and the Mint. The Mint is a Canadian Crown corporation, which acts as an agent of the Canadian Government, and its obligations generally constitute unconditional obligations of the Canadian Government. The Mint is responsible for and bears all risk of the loss of, and damage to, Sprott Physical Silver Trust's physical silver bullion that is in the Mint's custody, subject to certain limitations based on events beyond the Mint's control.

RBC Investor Services acts as custodian on behalf of Sprott Physical Silver Trust for Sprott Physical Silver Trust's assets other than physical silver bullion. RBC Investor Services is only responsible for Sprott Physical Silver Trust's assets that are directly held by it, its affiliates or appointed sub-custodian.

The Mint has its office located at 320 Sussex Drive, Ottawa, Ontario, Canada K1A 0G8, and RBC Investor Services has its office located at 155 Wellington Street West, Street Level, Toronto, Ontario, Canada M5V 3L3.

Under the PSLV Trust Agreement, the Manager, with the consent of the PSLV Trustee, may determine to change the custodial arrangements of Sprott Physical Silver Trust.

Sprott Physical Silver Trust invests primarily in long-term holdings of unencumbered, fully allocated, physical silver bullion and does not and will not speculate with regard to short-term changes in silver prices. Sprott Physical Silver Trust will not invest in silver certificates or other financial instruments that represent silver or that may be exchanged for silver. Sprott Physical Silver Trust does not anticipate making regular cash distributions to PSLV unitholders.

The value of the net assets of Sprott Physical Silver Trust and the value of the net assets of Sprott Physical Silver Trust per outstanding PSLV Unit are determined daily as of 4:00 p.m. (Toronto time) on each business day by Sprott Physical Silver Trust's valuation agent, RBC Investor Services. In addition, the Manager may calculate the value of the net assets of Sprott Physical Silver Trust and the NAV per PSLV Unit at such other times as the Manager deems appropriate. The value of the net assets of Sprott Physical Silver Trust on any such day is equal to the aggregate fair market value of the assets of Sprott Physical Silver Trust as of such date, less an amount equal to the fair value of the liabilities of Sprott Physical Silver Trust (excluding all liabilities represented by outstanding PSLV Units, if any) as of such date. The valuation agent calculates the NAV by dividing the value of the net assets of the class of Sprott Physical Silver Trust represented by PSLV Units on that day by the total number of PSLV Units of that class then outstanding on such day.

In making investments on behalf of Sprott Physical Silver Trust, the Manager is subject to certain investment and operating restrictions, (the "Investment and Operating Restrictions"), which are set out in the PSLV Trust Agreement. The Investment and Operating Restrictions may not be changed without the prior approval of PSLV Unitholders by way of an extraordinary resolution, which must be approved, in person or by proxy, by PSLV Unitholders holding PSLV Units representing in aggregate not less than 66²/3% of the value of the net assets of Sprott Physical Silver Trust as determined in accordance with the PSLV Trust Agreement, at a duly constituted meeting of PSLV Unitholders, or at any adjournment thereof, called and held in accordance with the PSLV Trust Agreement, or a written resolution signed by PSLV Unitholders holding PSLV Units representing in aggregate not less than 66²/3% of the value of the net assets of Sprott Physical Silver Trust as determined in accordance with the PSLV Trust Agreement, unless such change or changes are necessary to ensure compliance with applicable laws, regulations or other requirements imposed from time to time by applicable Securities Regulatory Authorities.

The Investment and Operating Restrictions provide that Sprott Physical Silver Trust:

Sprott Physical Silver Trust does not have a fixed termination date but will be terminated in the event there are no PSLV Units outstanding, the PSLV Trustee resigns or is removed and no successor trustee is appointed, the Manager resigns and no successor manager is appointed and approved by PSLV Unitholders, the Manager is in material default of its obligations under the PSLV Trust Agreement or the Manager experiences certain insolvency events. In addition, the Manager may, in its discretion, terminate Sprott Physical Silver Trust, without PSLV Unitholder approval, by giving the PSLV Trustee and each holder of PSLV Units at the time at least 90 days' notice. To the extent such termination in the discretion of the Manager may involve a matter that would be a "conflict of interest matter" as set forth under applicable Canadian securities legislation, the matter will be referred by the Manager to the independent review committee established by the Manager for its recommendation. In connection with the termination of Sprott Physical Silver Trust, Sprott Physical Silver Trust will, to the extent possible, convert its assets to cash and, after paying or making adequate provision for all of Sprott Physical Silver Trust's liabilities, distribute the net assets of Sprott Physical Silver Trust to PSLV Unitholders, on a pro rata basis, as soon as practicable after the termination date.

On February 27, 2015, the PSLV Trust Agreement was amended (the "UCITS Amendment") to permit investments in Sprott Physical Silver Trust from Undertakings for Collective Investments in Transferable Securities investors or others that are otherwise prohibited by their investment policies, guidelines or restrictions from receiving physical silver bullion. The UCITS Amendment consists of a restriction on such investors from redeeming units for physical silver bullion.

This table lists the fees and expenses that Sprott Physical Silver Trust pays for the continued operation of its business and that PSLV Unitholders pay if they invest in, or acquire units of, Sprott Physical Silver Trust. Payment of these fees and expenses will reduce the value of PSLV Unitholders' investment in Sprott Physical Silver Trust. PSLV unitholders will have to pay fees and expenses directly if they redeem their PSLV Units for physical silver bullion.

Type of Fee		Amount and Description

Management Fee:		Sprott Physical Silver Trust pays the Manager a monthly management fee equal to ¹/12 of 0.45% of the value of net assets of Sprott Physical Silver Trust (determined in accordance with the PSLV Trust Agreement), plus any applicable Canadian taxes (such as HST). The management fee is calculated and accrued daily and payable monthly in arrears on the last day of each month.
Operating Expenses:		Sprott Physical Silver Trust is responsible for all costs and expenses incurred in connection with the ongoing operation and administration of Sprott Physical Silver Trust including, but not limited to: the fees and expenses payable to and incurred by the PSLV Trustee, the Manager, any investment manager, the Mint, RBC Investor Services as custodian, any sub-custodians, the registrar, the transfer agent and the valuation agent of Sprott Physical Silver Trust; transaction and handling costs for the physical silver bullion including transportation costs for any physical silver bullion purchased for London delivery, which cost is expected to be approximately $0.080 per ounce; storage fees for the physical silver bullion (charged on a per bar basis currently at a rate of $2.25 per bar per month, subject to increase on 30 days' notice); custodian settlement fees; counterparty fees; legal, audit, accounting, bookkeeping and record keeping fees and expenses; costs and expenses of reporting to PSLV Unitholders and conducting PSLV Unitholder meetings; printing and mailing costs; filing and listing fees payable to applicable securities regulatory authorities and stock exchanges; other administrative expenses and costs incurred in connection with Sprott Physical Silver Trust's continuous disclosure public filing requirements and investor relations; any applicable Canadian taxes payable by Sprott Physical Silver Trust or to which Sprott Physical Silver Trust may be subject; interest expenses and borrowing costs, if any; brokerage expenses and commissions; costs and expenses relating to the issuance of trust units; costs and expenses of preparing financial and other reports; any expenses associated with the implementation and ongoing operation of the independent review committee of Sprott Physical Silver Trust; costs and expenses arising as a result of complying with all applicable laws; and any expenditures incurred upon the termination of Sprott Physical Silver Trust.

Sprott Physical Silver Trust has retained cash from the net proceeds of each of its offerings of units in an amount not exceeding 3% of the net proceeds of each of such offerings, which has been added to its available funds to be used for its ongoing expenses and cash redemptions. From time to time, Sprott Physical Silver Trust will sell physical silver bullion to replenish this cash reserve to meet its expenses and cash redemptions. There is no limit on the total amount of silver that Sprott Physical Silver Trust may sell in order to pay expenses, but the Manager intends that the cash reserve will not exceed 3% of the value of the net assets of Sprott Physical Silver Trust at any time.

Type of Fee		Amount and Description

Redemption and Delivery Costs:		Except as set forth below, there are no redemption fees payable upon the redemption of PSLV Units for cash. However, if a PSLV Unitholder chooses to receive physical silver bullion upon redemption of PSLV Units, the PSLV Unitholder will be responsible for expenses in connection with effecting the redemption and applicable delivery expenses, including the handling of the notice of redemption, the delivery of the physical silver bullion for PSLV Units that are being redeemed and the applicable silver storage in-and-out fees. Redemption requests for silver must be for amounts that are at least equivalent in value to ten London Good Delivery bars or an integral multiple of one bar in excess thereof, plus applicable expenses. A "London Good Delivery bar" contains between 750 and 1,100 troy ounces of silver with a minimum fineness of 999.0 parts per thousand silver. Assuming a price of silver of $22.00 per troy ounce, bars of 1,000 troy ounces, in-and-out fees charged by the Mint at $5 per bar and estimated delivery expenses at $0.50 per troy ounce, a minimum redemption request would need to be in an amount of approximately $225,050.
Other Fees and Expenses:		No other charges apply. If applicable, the PSLV Unitholder may be subject to brokerage commissions or other fees associated with trading the PSLV Units.

SBT is a passive, self-governing, single purpose, closed-end trust with voting units established on June 8, 2009 under the laws of the Province of Ontario by the SBT Declaration of Trust which was amended and restated on July 9, 2009. The principal and head office of SBT is located at 55 Broad Leaf Crescent, Ancaster, Ontario, Canada L9G 3P2. SBT's mailing address is Box 10106 Meadowlands Post Office, Ancaster, Ontario, Canada L9K 1P3. For further information regarding SBT, refer to SBT's filings with the Canadian and U.S. Securities Regulatory Authorities which may be obtained on SEDAR at www.sedar.com.

The SBT Units are listed on the TSX under the symbols "SBT.U" (U.S. dollar denominated) and "SBT.UN" (Canadian dollar denominated)".

As described in the management information circular of SBT dated April 24, 2015 prepared in connection with the annual and special of SBT Unitholders held on May 20, 2015 (the "SBT Meeting"), on February 3, 2015, the SBT Trustees received a SBT Unitholder meeting requisition (the "Polar Requisition") from Polar Securities Inc. ("Polar Securities") on behalf of its hedge fund North Pole Capital Master Fund (collectively with Polar Securities, "Polar"), SBT's largest unitholder. The Polar Requisition required that SBT submit two matters to SBT Unitholders for consideration: (i) a series of related ordinary resolutions in respect of removing certain incumbent SBT Trustees and appointing their successors; and (ii) a special resolution approving certain significant amendments to the redemption rights provisions of the SBT Declaration of Trust to implement a physical bullion redemption option as well as changes to the existing cash redemption provision (collectively, the "Polar Proposal").

On February 9, 2015, Polar publicly announced the Polar Proposal, following which the SBT Trustees and Polar engaged in a public proxy contest. The Manager monitored this proxy contest and become concerned that some of the statements being made by SBT were not necessarily accurate, especially with respect to the redemption and tax features of Sprott Physical Silver Trust. The Manager also became aware of the relatively consistent premium between the trading price of PSLV Units versus that of SBT Units (relative to their respective NAVs) and realized that the Manager and Sprott Physical Silver Trust were in a unique position to provide SBT Unitholders with a meaningful choice as to how their physical silver bullion is held and managed. As a result of the foregoing, the Manager began consideration of possible transactions involving the Manager, SBT and/or Sprott Physical Silver Trust.

The Manager continued to consider various possibilities in this regard, and engaged in certain related discussions with Polar, until April 22, 2015. Discussions with Polar did not result in any agreement, arrangement, commitment or understanding.

The Manager met with the Independent Review Committee of Sprott Physical Silver Trust on April 13, 2015 in connection with the proposed Offer. On April 13, 2015, the Independent Review Committee of Sprott Physical Silver Trust provided its recommendation to the Manager that in the Independent Review Committee's opinion after reasonable inquiry, the Offer achieves a fair and reasonable result for Sprott Physical Silver Trust and approved the Offer and the Merger Transaction.

On April 22, 2015, the board of directors of Sprott Inc., the parent company of the Manager, approved the Manager publicly announcing an intention to commence the Offer.

On April 23, 2015, the Manager and Sprott Physical Silver Trust publicly announced an intention to commence the Offer.

On May 25, 2015, the sole director of SAM Silver Bid GP and the board of directors of SAM GP Inc. determined to formally commence the Offer. Simultaneously with the Offer, Sprott Asset Management Gold Bid LP, a limited partnership that is owned and controlled by the Manager, commenced an offer to purchase, on the terms and subject to the conditions set out therein, all of the issued and outstanding units of Central GoldTrust, other than any units held directly or indirectly by Sprott Asset Management Gold Bid LP, for consideration consisting of units of Sprott Physical Gold Trust.

SBT Unitholders should consider the following factors in making a decision to participate in the Offer:

The Manager and the Offeror believe that SBT units persistently trade at a discount to NAV because SBT management does not reinvest the fees it collects to support the product. Additionally, SBT features a punitive redemption feature that forces unitholders to redeem their units for less than market value. Unlike Sprott Physical Silver Trust, SBT does not allow its unitholders to redeem for physical silver. The Manager actively markets Sprott Physical Silver Trust to retail and institutional investors.

The Manager is a global leader in precious metals investing and is committed to creating value for investors in its products. The Manager has a proven track record and best-in-class platform, which it believes can assist in addressing the persistent trading discounts endured by SBT unitholders. The Manager believes that this commitment to marketing creates buying demand that supports the price of PSLV Units. These efforts are further supported by Sprott Physical Silver Trust's industry-leading physical redemption feature.

Based on the closing prices of the SBT Units and the PSLV Units on the TSX (SBT.UN) and NYSE Arca, respectively, on April 22, 2015, being the last trading day prior to the public announcement of the Manager's intention to commence the Offer, the SBT Units were trading at a -10.3% discount to NAV while the PSLV Units were trading at a 1.07% PREMIUM to NAV. These spreads have been relatively consistent over a prolonged period of time.

43

Time is of the essence. Send in your SBT Units with a completed YELLOW Letter of Transmittal to the Depositary or call your broker now to deposit.

The Offeror and the Manager believe that the narrowing of this spread is a result of the announcement of the Manager's intention to commence the Offer. If the Offer is successful, the Manager and the Offeror believe that current SBT Unitholders, by owning PSLV Units, will see a meaningful reduction in the persistent NAV discount impacting their current investment in SBT Units.

The Manager has become aware that SBT's largest unitholder, Polar Securities, which owns or controls approximately 10.02% of the outstanding SBT Units, supports the Offer.

Unlike SBT, which stores its silver in a commercial bank vault, the silver held by Sprott Physical Silver Trust is stored more securely outside of the banking system, at the Royal Canadian Mint, under the guarantee and protection of the Canadian Federal Government.

The incumbent SBT Trustees have publicly asserted that SBT's expense ratio is "among the lowest" relative to comparable U.S. and Canadian bullion products. However, the Offeror believes SBT's expense ratio is high given the SBT Trustees' and the Administrator's limited scope of duties, responsibilities and actions, including the lack of any duties or responsibilities in connection with redeeming units for physical bullion.

The incumbent SBT Trustees, including the independent committee formed in response to the Polar Proposal, claim that they are independent from the Administrator and its owner J.C. Stefan Spicer. However, all of the incumbent SBT Trustees also sit, or have sat, on at least one of the boards of two other bullion funds managed by Mr. Spicer. In addition, a number of the incumbent SBT Trustees have participated in a variety of business ventures with Mr. Spicer. SBT Unitholders should evaluate for themselves whether the incumbent SBT Trustees are independent from Mr. Spicer and the Administrator.

Following the Merger Transaction, SBT is anticipated to have nominal, if any, assets and liabilities. If permitted by applicable Law and otherwise advisable, subsequent to the completion of the Offer and the Merger Transaction, the Offeror will consider taking steps to cause the delisting of the SBT Units from the TSX and to cause SBT to cease to be a reporting issuer under the securities laws of each of the provinces and territories of Canada in which it has such status. See Section 19 of the Circular, "Effect of the Offer and the Merger Transaction on the Market for and Listing of SBT Units and Status as a Reporting Issuer".

These plans are based on information currently available to the Offeror. Except as otherwise indicated herein, the Offeror has so far had an opportunity to review only SBT's public disclosure filed with Canadian and U.S. securities regulatory authorities. As a result, the foregoing plans for SBT may change if more information becomes available.

7. Summary of Sprott Physical Silver Trust's Historical and Pro Forma Financial Information

SBT Unitholders should refer to Schedule "A" to this Offer and Circular for Sprott Physical Silver Trust's unaudited pro forma financial statements as at and for the three months ended March 31, 2015 and for the year ended December 31, 2014, giving effect to the proposed acquisition of substantially all of the assets and liabilities of SBT (other than the Administration Agreement) in the manner set forth therein. Such pro forma financial statements are not intended to be indicative of the results that would actually have occurred, or the results expected in future periods, had the events reflected herein occurred on the dates indicated. Actual amounts recorded upon consummation of the transactions contemplated by the Offer will differ from such pro forma financial statements. Any potential synergies that may be realized after consummation of the transaction have been excluded from such pro forma financial statements. Since the pro forma financial statements have been developed to retroactively show the effect of a transaction that is expected to occur at a later date (even though this was accomplished by following generally accepted practice and using reasonable assumptions), there are limitations inherent in the very nature of such pro forma data. The data contained in the pro forma financial statements represents only a simulation of the potential impact of Sprott Physical Silver Trust's acquisition of substantially all of the assets and liabilities of SBT (other than the Administration Agreement). SBT Unitholders are cautioned to not place undue reliance on such pro forma financial statements.

The table set out below includes a summary of Sprott Physical Silver Trust's historical financial information as at and for the years ended December 31, 2014 and 2013 and the three months ended March 31, 2015, prepared in accordance with IFRS.

The unaudited pro forma financial statements for Sprott Physical Silver Trust have been derived from: (i) the audited financial statements of each of Sprott Physical Silver Trust and SBT for the year ended December 31, 2014; and (ii) the unaudited financial statements of each of Sprott Physical Silver Trust and SBT as at and for the three months ended March 31, 2015.

The unaudited pro forma financial statements for Sprott Physical Silver Trust give effect to Sprott Physical Silver Trust's proposed acquisition of substantially all of the assets and liabilities of SBT (other than the Administration Agreement) as if it had occurred as at March 31, 2015, for the purposes of the pro forma balance sheet information and as at January 1, 2014 for the purposes of the pro forma statements of earnings for the year ended December 31, 2014 and for the three months ended March 31, 2015. In preparing the unaudited pro forma financial statements, the Offeror has made certain assumptions that affect the amounts reported in the unaudited pro forma financial statements. The unaudited pro forma financial statements are not intended to be indicative of the results that would actually have occurred, or the results expected in future periods, had the events reflected herein occurred on the dates indicated. Actual amounts recorded upon consummation of the Offer and the Merger Transaction will differ from the pro forma information presented below. Pro forma adjustments have been made to account for significant accounting policy differences identified as of the date of this Offer and Circular. The review undertaken by the Offeror was to identify significant accounting policy differences where the impact was potentially material and could reasonably be estimated. Further accounting

policy differences may be identified after the consummation of the proposed transactions. Any potential synergies that may be realized after consummation of the proposed transactions have been excluded from the unaudited pro forma financial statements.

Time is of the essence. Send in your SBT Units with a completed YELLOW Letter of Transmittal to the Depositary or call your broker now to deposit.

Subject to the terms of the PSLV Trust Agreement, PSLV Units may be redeemed at the option of a PSLV Unitholder for physical silver bullion in any month. PSLV Units redeemed for physical silver bullion will be entitled to a redemption price equal to 100% of the NAV of the redeemed PSLV Units on the last day of the month on which NYSE Arca is open for trading for the month in which the redemption request is processed. Redemption requests for silver must be for amounts that are at least equivalent to the value of ten London Good Delivery bars or an integral multiple of one bar in excess thereof, plus applicable expenses. A "London Good Delivery bar" weighs between 750 and 1,110 troy ounces (approximately 23 to 34 kilograms) and usually are approximately 1,000 troy ounces. Any fractional amount of redemption proceeds in excess of ten London Good Delivery bars or an integral multiple of one bar in excess thereof will be paid in cash at a rate equal to 100% of the NAV of such excess amount. The ability of a unitholder to redeem units for physical silver bullion may be limited by the sizes of London Good Delivery bars held by Sprott Physical Silver Trust at the time of redemption. A PSLV Unitholder redeeming PSLV Units for physical silver bullion will be responsible for expenses incurred by Sprott Physical Silver Trust in connection with such redemption and applicable delivery expenses, including the handling of the notice of redemption and the delivery of the physical silver bullion for PSLV Units. A redemption notice to redeem PSLV Units for physical silver bullion must be received by Sprott Physical Silver Trust's transfer agent no later than 4:00 p.m. (Toronto time) on the 15th day of the month in which the redemption notice will be processed or, if such day is not a business day, on the immediately following day that is a business day. Any redemption notice received after such time will be processed in the next month. For each redemption notice, Sprott Physical Silver Trust's transfer agent will send a confirmation notice to the PSLV Unitholder's broker that such notice has been received and determined to be complete.

Physical silver bullion received by a PSLV Unitholder as a result of a redemption of PSLV Units will be delivered by armored transportation service carrier pursuant to delivery instructions provided by the PSLV Unitholder to the Manager. Physical silver bullion transported to an account established by the redeeming PSLV Unitholder at an institution authorized to accept and hold London Good Delivery bars by certain armored transportation service carriers will likely retain its London Good Delivery status while in the custody of such institution; physical silver bullion delivered pursuant to a PSLV Unitholder's delivery instruction to a destination other than such an institution will no longer be deemed London Good Delivery once received by the PSLV Unitholder. The armored transportation service carrier will receive physical silver bullion in connection with a redemption of PSLV Units approximately 10 business days after the end of the month in which the redemption notice is processed.

Subject to the terms of the PSLV Trust Agreement, PSLV Units may be redeemed at the option of a PSLV Unitholder for cash on a monthly basis. PSLV Units redeemed for cash will be entitled to a redemption price equal to 95% of the lesser of: (i) the volume-weighted average trading price of the PSLV Units traded on NYSE Arca or, if trading has been suspended on NYSE Arca, the trading price of the PSLV Units traded on the TSX, for the last five days on which the respective exchange is open for trading for the month in which the redemption request is processed; and (ii) the NAV of the redeemed PSLV Units as of 4:00 p.m. (Toronto time) on the last day of the month on which NYSE Arca is open for trading for the month in which the redemption request is processed. Cash redemption proceeds will be transferred to a redeeming PSLV Unitholder approximately three business days after the end of the month in which the redemption notice is processed.

A redemption notice to redeem PSLV Units for cash must be received by Sprott Physical Silver Trust's transfer agent no later than 4:00 p.m. (Toronto time) on the 15th day of the month in which the redemption notice will be processed or, if such day is not a business day, then on the immediately following day that is a business day. Any redemption notice to redeem PSLV Units for cash received after such time will be processed in the next month.

14. Summary Comparison of Material Differences between the PSLV Trust Agreement and the SBT Declaration of Trust and of the Canadian Securities Regulatory Regime for Investment Funds and Public Companies

The following is a summary of the material differences between the PSLV Trust Agreement and the SBT Declaration of Trust. This summary is not an exhaustive review of the two documents. Reference should be made to the full text of both the PSLV Trust Agreement and the SBT Declaration of Trust. Copies of each of the PSLV Trust Agreement and the SBT Declaration of Trust are available electronically on SEDAR at www.sedar.com and the PSLV Trust Agreement is also available on EDGAR at www.sec.gov.

Each of the PSLV Trust Agreement and the SBT Declaration of Trust provide that Sprott Physical Silver Trust and SBT, respectively, must hold a minimum of 90% of their total net assets in physical silver bullion. The PSLV Trust Agreement stipulates that the physical silver bullion must be in London Good Delivery bar form and that Sprott Physical Silver Trust may not invest in silver certificates or other financial instruments that represent silver or that may be exchanged for silver whereas the SBT Declaration of Trust is silent on the form of the physical silver bullion. In respect of the remaining assets that may be held by each of Sprott Physical Silver Trust and SBT: (i) the PSLV Trust Agreement states that Sprott Physical Silver Trust may not hold more than 10% of its total net assets in physical silver bullion (in London Good Delivery Bar form or otherwise), debt obligations of or guaranteed by the Government of Canada or a province of Canada or by the Government of the United States of America or a state thereof, interest-bearing accounts, short-term certificates of deposit issued

or guaranteed by a Canadian chartered bank or trust company, money market mutual funds, and short-term government debt or short-term investment grade corporate debt; and (ii) the SBT Declaration of Trust states that SBT may not hold more than 10% of its total net assets in (A) silver certificates to enable payments, if any, made in connection with the redemption of any SBT Units or other securities of SBT, for making distributions, if any, to SBT Unitholders, and for working capital purposes, and (B) cash and interest-bearing accounts, money market mutual funds, debt obligations of or guaranteed by the Government of Canada or a province of Canada or by the Government of the United States of America or a state thereof, interest-bearing accounts, short-term certificates of deposit issued or guaranteed by a Canadian chartered bank or trust company, short-term government debt or short-term investment grade corporate debt for working capital purposes.

The PSLV Trust Agreement allows PSLV Unitholders to redeem PSLV Units for physical silver bullion in any month. PSLV Units redeemed for physical silver bullion will be entitled to a redemption price equal to 100% of the NAV of the redeemed PSLV Units on the last day of the month on which NYSE Arca is open for trading for the month in which the redemption request is processed. A PSLV Unitholder redeeming PSLV Units for physical silver bullion will be responsible for expenses incurred by Sprott Physical Silver Trust in connection with such redemption and applicable delivery expenses, including the handling of the notice of redemption, the delivery of the physical silver bullion for the PSLV Units. Physical silver bullion received by a PSLV Unitholder as a result of a redemption of PSLV Units will be delivered by armored transportation service carrier pursuant to delivery instructions provided by the PSLV Unitholder to the Manager. See Section 8 of the Circular "Certain Information Concerning the Securities of Sprott Physical Silver Trust — Redemption of PSLV Units for Physical Silver Bullion".

The SBT Trust Agreement does not permit SBT Unitholders to redeem SBT Units for physical silver bullion.

Each of the PSLV Trust Agreement and the SBT Declaration of Trust allow PSLV Unitholders and SBT Unitholders, respectively, to redeem PSLV Units and SBT Units, respectively, for cash. The cash redemption features of the PSLV Units and SBT Units are described below.

PSLV Units may be redeemed at the option of a PSLV Unitholder for cash on a monthly basis. PSLV Units redeemed for cash will be entitled to a redemption price equal to 95% of the lesser of: (i) the volume-weighted average trading price of the PSLV Units traded on NYSE Arca or, if trading has been suspended on NYSE Arca, the trading price of the PSLV Units traded on the TSX, for the last five days on which the respective exchange is open for trading for the month in which the redemption request is processed; and (ii) the NAV of the redeemed PSLV Units as of 4:00 p.m. (Toronto time) on the last day of the month on which NYSE Arca is open for trading for the month in which the redemption request is processed. See Section 8 of the Circular "Certain Information Concerning the Securities of Sprott Physical Silver Trust — Redemption of PSLV Units for Cash".

SBT Units may be redeemed at any time on demand by SBT Unitholders for cash. SBT Units redeemed for cash will be entitled to a redemption price equal to the lesser of: (i) 90% of the Market Price on the principal market or exchange on which the SBT Units are quoted for trading during the 10 trading day period commencing immediately following the date on which the SBT Units were tendered for redemption (the "Redemption Date"); and (ii) 100% of the Closing Market Price on the principal market on which the SBT Units are quoted for trading on the Redemption Date. "Market Price" shall be the amount equal to the weighted average of the trading prices of the SBT Units on the applicable market or exchange for each of the trading days on which there was a trade during the specified trading day period; provided that if there was trading on the applicable exchange or market for fewer than five of the trading days during the specified trading day period, "Market Price" shall be the average of the following prices established for each of the trading days during the specified trading day period: the average of the last bid and last asking prices for each day on which there was no trading and the weighted average trading prices of the SBT Units for each day that there was trading. "Closing Market Price" means: (i) an amount equal to the closing price of the SBT Units on the

51

applicable market or exchange if there was a trade on the specified date and the applicable exchange or market provides a closing price; (ii) an amount equal to the average of the highest and lowest prices of SBT Units on the applicable market or exchange if there was trading on the specified date and the applicable exchange or market provides only the highest and lowest trading prices of SBT Units traded on a particular day; or (iii) the average of the last bid and last asking prices if there was no trading on the specified date.

The Manager, on behalf of Sprott Physical Silver Trust, may suspend the right of PSLV Unitholders to request a redemption of their PSLV Units or postpone the date of delivery or payment of the redemption proceeds (whether silver bullion and/or cash, as the case may be) with the prior approval of Canadian Securities Regulatory Authorities having jurisdiction, where required, for any period during which the Manager determines that conditions exist which render impractical the sale of assets of Sprott Physical Silver Trust or which impair the ability of the Manager to determine the Net Asset Value of Sprott Physical Silver Trust and the Net Asset Value per PSLV Unit or the redemption amount for the PSLV Units. The SBT Declaration of Trust does not address the ability of the Trustees, the Administrator or SBT to suspend the redemption of SBT Units.

Each of the PSLV Trust Agreement and the SBT Declaration of Trust permit PSLV Unitholders and SBT Unitholders, respectively, to requisition meetings and outline certain meeting requirements, including quorum.

PSLV Unitholders holding PSLV Units representing in aggregate not less than 50% of the Net Asset Value of Sprott Physical Silver Trust may requisition a meeting of PSLV Unitholders by giving a written notice to the Manager or the PSLV Trustee setting out in detail the reason(s) for calling and holding such a meeting. SBT Unitholders holding at least 10% of the SBT Units may requisition the SBT Trustees to call a special meeting of SBT Unitholders by giving notice to SBT Trustees setting out in detail the reason(s) for calling and holding such a meeting.

A quorum for the transaction of business at any meeting of PSLV Unitholders shall be at least two PSLV Unitholders holding not less than 5% of the outstanding PSLV Units on such date present in person or represented by proxy and entitled to vote thereat. A quorum for the transaction of business at any meeting of SBT Unitholders shall consist of five or more individuals present in person either holding personally or representing as proxies not less in aggregate than 10% of the SBT Units outstanding entitled to vote thereat.

Canadian Securities Regulatory Regime for Investment Funds and Public Companies

Under applicable Canadian securities legislation, Sprott Physical Silver Trust is considered an investment fund and is subject to the Canadian securities regulatory regime for investment funds (the "Investment Fund Regime").

If the Offer and Merger are successful, SBT Unitholders will receive PSLV Units and therefore will hold securities of an issuer, Sprott Physical Silver Trust, that complies with the Investment Fund Regime, as opposed to the Canadian securities regulatory regime for issuers that are not investment funds (the "Public Company Regime"). For a summary comparison of the differences between the Investment Fund Regime and the Public Company Regime, see Schedule C.

If the Merger is completed, SBT Unitholders that make a Merger Election and Non-Depositing SBT Unitholders will receive PSLV Units in exchange for their SBT Units on a tax-deferred "roll-over" basis pursuant to the mechanics of the Merger. By making a Merger Election, Merger Electing SBT Unitholders will deposit the Merger Elected SBT Units in the Offer and then will be deemed to have withdrawn such Merger Elected SBT Units from the Offer, effective at 4:59 p.m. (Toronto time) on the Expiry Date. Accordingly, if the Merger is completed, Merger Elected SBT Units will not be taken-up and paid for under the Offer but such Merger Elected SBT Units will participate in the Merger and Merger Electing SBT Unitholders will receive PSLV upon the redemption of their SBT Units as part of the Merger Transaction. The deemed withdrawal will

52

neither revoke the Special Resolutions Power of Attorney nor require the Depositary to return the Merger Elected SBT Units.

As described under Section 3 of the Offer, "Manner of Acceptance", Merger Electing SBT Unitholders will provide the Special Resolutions Power of Attorney, through the execution of the Letter of Transmittal. As a consequence, all Merger Electing SBT Unitholders will be approving the Special Resolutions. Following the approval of the Special Resolutions by Depositing SBT Unitholders representing 66²/3% or more of the then outstanding SBT Units through the Special Resolutions Power of Attorney, the Offeror intends to enter into the Merger Agreement on behalf of SBT.

The Offeror's current intention is to complete the Merger (including the distribution of PSLV Units to SBT Unitholders upon the redemption of the outstanding SBT Units) immediately following and conditional on the take-up of and payment for Tendered SBT Units under the Offer. This is intended to provide the most consistent treatment possible to all SBT Unitholders, whether they are exchanging SBT Units for PSLV Units under the Offer or as a result of the Merger.

Right to Withdraw SBT Units in Respect of Which a Merger Election Has Been Made

In order not to provide the Special Resolutions Power of Attorney, withdrawals of Merger Elected SBT Units must be effected prior to 4:58 p.m. (Toronto time) on the Expiry Date. A notice of withdrawal of such Merger Elected SBT Units must actually be received by the Depositary prior to 4:58 p.m. (Toronto time) on the Expiry Date in a manner such that the Depositary has a written or printed copy of such notice of withdrawal. Merger Electing SBT Unitholders should contact their broker or other nominee for assistance.

A Merger Electing SBT Unitholder's broker or other nominee may set deadlines for the withdrawal of Merger Elected SBT Units prior to 4:58 p.m. (Toronto time) on the Expiry Date that are earlier than those specified above. Merger Electing SBT Unitholders should contact their broker or other nominee for assistance.

All questions as to the validity (including timely receipt) and form of notices of withdrawal will be determined by the Offeror in its sole discretion, and such determination will be final and binding. There will be no obligation on the Offeror, the Depositary or any other Person to give any notice of any defects or irregularities in any withdrawal and no liability will be incurred by any of them for failure to give any such notice. The Offeror reserves the right to permit withdrawals of Merger Elected SBT Units deposited to the Offer and in respect of which a Merger Election has been made other than as set forth herein.

No further action on the part of the Merger Electing SBT Unitholders is required to withdraw such Merger Elected SBT Units from the Offer as at 4:59 p.m. (Toronto time) on the Expiry Date, as such Merger Elected SBT Units will be deemed to have been withdrawn at such time in order to participate in the Merger Transaction.

If the Special Resolutions are approved by Depositing SBT Unitholders and if the Merger is completed, Non-Depositing SBT Unitholders will receive PSLV Units under the Merger as if they had made a Merger Election.

Conditional on the approval of the Special Resolutions, the Offeror intends to sign and deliver, on behalf of SBT, a merger agreement (the "Merger Agreement") with Sprott Physical Silver Trust at 4:58 p.m. (Toronto time) on the Expiry Date. The following is a summary of the material terms of the proposed Merger Agreement. It is qualified in its entirety by reference to the full text thereof, a copy of which will be made available on Sprott Physical Silver Trust's website at www.sprottphysicalbullion.com, and the terms thereof are subject to change. SBT Unitholders who would like a paper copy to be mailed to them without charge may contact Director of Communications at the Manager at Royal Bank Plaza, South Tower, 200 Bay Street, Suite 2700, PO Box 27, Toronto, Ontario, Canada M5J 2J1 (telephone: 1-416-362-7172).

The closing of the transactions under the Merger Agreement would occur, subject to the terms and conditions of the Merger Agreement, on such date as is specified in writing by Sprott Physical Silver Trust, which is currently expected to occur immediately following and conditional on the take-up of and payment for Tendered SBT Units under the Offer. SBT would then redeem all outstanding SBT Units (including Merger Elected SBT Units, Non-Deposited SBT Units and Tendered SBT Units purchased by the Offeror under the Offer) and distribute the PSLV Units to such holders of SBT Units on the same terms as under the Offer. Any PSLV Units received by the Offeror as a holder of SBT Units at such time would be transferred to Sprott Physical Silver Trust and be cancelled. Notwithstanding the foregoing, the Offeror may retain or reacquire one SBT Unit in its discretion to keep SBT in existence.

If the Offeror determines, in its sole discretion, that it is desirable or required by Law to do so, SBT shall, in respect of any PSLV Units that would otherwise be received by any one or more former beneficial SBT Unitholder(s) or class(es) thereof in connection with the Offer or the Merger Transaction in any one or more non-Canadian or non-U.S. jurisdiction(s), distribute such PSLV Units to a person designated by the Offeror who shall receive the PSLV Units as agent for such persons and shall, as agent for such persons, as expeditiously as is commercially reasonable thereafter, sell such PSLV Units through the facilities of the TSX or NYSE Arca and pay to such persons the net proceeds thereof, after disposition costs and less any applicable withholding taxes and without interest. The Offeror shall not have any liability to any person in connection with the sale of PSLV Units in accordance with the foregoing. No trustee, broker or agent designated by the Offeror to effect a sale of PSLV Units in accordance with the foregoing shall have any liability to SBT or any affected beneficial SBT Unitholder in connection therewith, except for gross negligence or willful misconduct.

In the Merger Agreement, while there would be no representations or warranties of either party, SBT would agree to: (i) co-operate (and to cause its advisors to co-operate) in proceeding with the transactions contemplated therein (including, without limitation, cooperation with respect to any regulatory or stock exchange filings) and not to take any actions inconsistent therewith; (ii) conduct its business and activities in the ordinary course in substantially the same manner as previously conducted, except that it will not: (a) enter into or renew or amend any material agreements (including without limitation administration, custodial or insurance arrangements), or (b) make any material capital expenditures, or (c) make any business acquisitions or dispositions, or (d) make any changes to its capitalization (including borrowings or guarantees), or (e) declare or make any payments or distributions to its securityholders, or (f) make any payments to, or enter into or renew or amend any agreements or arrangements with, any of its trustees, directors or officers, or (g) make any changes to its accounting practices, or (h) settle any litigation or claims, in each case without Sprott Physical Silver Trust's prior express written approval; (iii) forthwith, upon request, provide full access or cause full access and cooperation to be provided to Sprott Physical Silver Trust and its representatives to its records, premises, employees and advisors; (iv) not amend the SBT Declaration of Trust, except with the prior express written approval of Sprott Physical Silver Trust; (v) not sell, pledge, encumber, allot, reserve, set aside or issue, authorize or propose the sale, pledge, encumbrance, allotment, reservation, setting aside or issuance of, or purchase or redeem or propose the purchase or redemption of, any securities of SBT or any class of securities convertible or exchangeable into, or rights, warrants or options to acquire, any such securities, in each case without Sprott Physical Silver Trust's prior express written approval or other than in connection with the Merger; (vi) take or fail to take any action within its reasonable control which would result in a condition specified in the Merger Agreement not being satisfied; (vii) prepare and execute, and assist Sprott Physical Silver Trust with its preparation and registration of, all documents required in connection with the conveyancing and transfer of the SBT assets; and (viii) immediately advise Sprott Physical Silver Trust verbally and in writing of any material developments or changes with respect to its business, operations and affairs, and to send Sprott Physical Silver Trust for its comments a copy of any press release, material change report or any other document proposed to be filed with any Securities Regulatory Authority as sufficiently in advance of filing or release as is possible.

The closing of the transactions contemplated in the Merger Agreement would be subject to the take-up of, and payment for, Tendered SBT Units under the Offer. If any of the conditions were not to be satisfied or

54

waived by the Offeror, then Sprott Physical Silver Trust would be entitled to terminate the Merger Agreement, without prejudice to any other remedies (including damages or equitable remedies) that it may have. Each party to the Merger Agreement would be responsible for its own expenses (provided however that the Offeror and the Manager have separately agreed with Sprott Physical Silver Trust to pay all costs and expenses of Sprott Physical Silver Trust), and the Merger Agreement would be governed by the laws of Ontario.

In order to permit the Merger Transaction, prior to the Offeror taking up any Tendered SBT Units under the Offer, the Offeror currently intends to:

in each case, by resolutions in writing signed by SBT Unitholders holding 66²/3% or more of the outstanding SBT Units (the "Special Resolutions") rather than seeking SBT Unitholders' approval at a special meeting to be called for that purpose, all in accordance with the SBT Declaration of Trust. The Offeror intends to use the Special Resolutions Power of Attorney to pass the Special Resolutions before the Offeror takes up and pays for Tendered SBT Units under the Offer.

Capitalized terms used and not defined in these resolutions have the meanings given to them in the Offer and Circular of Sprott Asset Management Silver Bid LP dated May 27, 2015, as amended from time to time (the "Offer and Circular").

55

Time is of the essence. Send in your SBT Units with a completed YELLOW Letter of Transmittal to the Depositary or call your broker now to deposit.

In addition to approval of the foregoing Special Resolutions, the Manager would have to approve the entering into of, and enter into, the Merger Agreement on the part of Sprott Physical Silver Trust.

Multilateral Instrument 61-101 — Protection of Minority Security Holders in Special Transactions ("MI 61-101") may deem a transaction such as the Merger Transaction to be a "business combination" if it would result in the interest of a SBT Unitholder being terminated without the consent of the holder, irrespective of the nature of the consideration provided in substitution therefor. As the Merger Transaction will have been approved by Depositing SBT Unitholders prior to the taking up of Tendered SBT Units by the Offeror under the Offer, and as the Offeror currently intends the Merger Agreement to be entered into pursuant to such approval and authority prior to the Expiry Time, the Offeror believes that the Merger Transaction will not constitute a "business combination" for the purposes of MI 61-101, and thus will not be subject to MI 61-101.

Rule 13e-3 under the U.S. Exchange Act is applicable to certain "going-private" transactions in the United States and may under certain circumstances be applicable to a transaction such as the Merger Transaction. The Offeror believes that Rule 13e-3 under the U.S. Exchange Act should not be applicable to the Merger Transaction unless the Merger Transaction is consummated more than one year after the termination of the Offer. If applicable, Rule 13e-3 under the U.S. Exchange Act would require, among other things, that certain financial information concerning SBT and certain information relating to the fairness of the Merger Transaction and the consideration offered to minority unitholders be filed with the SEC and distributed to minority unitholders before the consummation of the Merger Transaction.

The foregoing discussion of certain provisions of the U.S. Exchange Act is not a complete description of the U.S. Exchange Act or such provisions thereof and is qualified in its entirety by the reference to the U.S. Exchange Act.

There are no arrangements or agreements made or proposed to be made between the Offeror, the Manager, SAM Silver Bid GP, SAM GP Inc. or Sprott Physical Silver Trust, on one hand, and SBT, on the other hand, or between the Offeror, the Manager, SAM Silver Bid GP, SAM GP Inc. or Sprott Physical Silver Trust, on one hand, and any of the SBT Trustees, on the other hand.

The Manager has become aware that Polar is supportive of the Offer, but there are no contracts, arrangements or understandings, formal or informal, between the Offeror, the Manager, SAM Silver Bid GP, SAM GP Inc. or Sprott Physical Silver Trust, on one hand, and any security holder of SBT, on the other hand, with respect to the Offer or the Merger Transaction or between the Offeror, the Manager, SAM Silver Bid GP, SAM GP Inc. or Sprott Physical Silver Trust, on one hand, and any person or company, on the other hand, with respect to any securities of SBT in relation to the Offer or the Merger Transaction.

Other than the benefits that Sprott Physical Silver Trust expects to realize as a result of any increased asset base resulting from the Merger Transaction and additional fees that will be payable to the Manager under the PSLV Management Agreement as a result of such increased asset base, no person referred to in Section 10 of the Circular, "Holdings of Securities of SBT", will receive any direct or indirect benefit from the consummation of the Offer or the Merger Transaction or from accepting or refusing to accept the Offer.

Based upon an examination of SBT's public disclosure, the Offeror is not aware of any governmental licences or regulatory permits that appear to be material to the business of SBT which might be adversely affected by completion of the Offer or the Merger Transaction.

In connection with the Offer and the Merger Transaction, the approval on terms reasonably satisfactory to the Offeror of various Canadian and U.S. regulatory authorities having jurisdiction over the Offeror or SBT is required. The principal approvals required are described below.

The distribution of the PSLV Units under the Offer and the Merger Transaction is being made pursuant to statutory exemptions from the prospectus and dealer registration requirements under applicable Canadian securities laws. While the resale of PSLV Units issued under the Offer or the Merger Transaction is subject to restrictions under the securities laws of certain Canadian provinces and territories, SBT Unitholders in such provinces and territories generally will be able to rely on statutory exemptions from such restrictions.

The Offeror has filed the Registration Statement on Form F-10 with the SEC registering the issuance of the PSLV Units offered to U.S. SBT Unitholders pursuant to the Offer and Merger Transaction as required by the U.S. Securities Act of 1933 (the "U.S. Securities Act"). The resale of the PSLV Units offered to U.S. Unitholders by persons that are not "affiliates" (as defined in Rule 144 under the U.S. Securities Act), and have not been "affiliates" at any time during the 90 days prior to the consummation of the Offer, of the Offeror will not be required to be registered in the United States. However, PSLV Units acquired pursuant to the Offer by "affiliates" (as defined in Rule 144 under the U.S. Securities Act) of the Offeror may be resold only in a transaction registered under the U.S. Securities Act or in accordance with the requirements of Rule 144 under the U.S. Securities Act or another exemption from the registration requirements of the U.S. Securities Act. In general, an "affiliate" (as defined in Rule 144 under the U.S. Securities Act) of the Offeror may include an executive officer or director of SAM Silver Bid GP or SAM GP Inc., a SBT Unitholder who beneficially owns more than 10% of the issued and outstanding PSLV Units or other individuals or entities that, directly or indirectly, through one or more intermediaries, control, or are controlled by or are under common control with the Offeror. This document does not constitute a registration statement covering resales of securities by persons who are otherwise restricted from selling their units under the U.S. Securities Act.

The Offer is being made in compliance with applicable Canadian and U.S. rules governing take-over bids and tender offers, respectively, or applicable exemptions therefrom.

THE PSLV UNITS OFFERED PURSUANT TO THE OFFER AND CIRCULAR HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SEC, NOR HAS THE SEC PASSED UPON THE ACCURACY OR ADEQUACY OF THE OFFER AND CIRCULAR. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

In connection with the Offer and the Merger Transaction, and using the Net Asset Value per unit of Sprott Physical Silver Trust and SBT as of May 22, 2015 (calculated in a manner consistent with the NAV to NAV Exchange Ratio) by way of example only, Sprott Physical Silver Trust expects to issue up to approximately 8,205,762 PSLV Units, representing approximately 6.05% of the PSLV Units issued and outstanding immediately

57

prior to the completion of the Offer and the Merger Transaction. Sprott Physical Silver Trust has applied to list such PSLV Units on the TSX and will apply to list such PSLV Units on NYSE Arca, and the listing of such units on the TSX and NYSE Arca is a condition of the Offer. Listing will be subject to fulfillment of all of the applicable listing requirements and the approval of the TSX and NYSE Arca. The TSX has provided its conditional approval of the listing of PSLV Units on the TSX in connection with the Offer and the Merger Transaction.

19. Effect of the Offer and the Merger Transaction on the Market for and Listing of SBT Units and Status as a Reporting Issuer

Following the Merger Transaction, SBT is anticipated to have nominal, if any, assets and liabilities. If permitted by applicable Law and otherwise advisable, subsequent to the completion of the Offer and the Merger Transaction, any PSLV Units received by the Offeror as holder of SBT Units will be returned to Sprott Physical Silver Trust for cancellation and the Offeror will consider taking steps to cause the delisting the SBT Units from the TSX and to cause SBT to cease to be a reporting issuer under the securities laws of each of the provinces and territories of Canada in which it has such status.

In the opinion of Stikeman Elliott LLP, Canadian counsel to the Offeror, the following is a summary of the principal Canadian federal income tax considerations under the Tax Act generally applicable to a SBT Unitholder who: (i) disposes of SBT Units to the Offeror in exchange for PSLV Units pursuant to the Exchange Offer Election, or (ii) disposes of SBT Units to SBT in exchange for PSLV Units on the redemption of SBT Units pursuant to the Merger. This summary is generally applicable to a SBT Unitholder who deals at arm's length and is not affiliated with SBT or Sprott Physical Silver Trust, and holds SBT Units and will hold PSLV Units received in exchange therefor as capital property. SBT Units and PSLV Units generally will be considered capital property to a SBT Unitholder unless the SBT Unitholder holds such units in the course of carrying on a business, or the SBT Unitholder has acquired them in a transaction or transactions considered to be an adventure in the nature of trade. Certain SBT Unitholders who are resident in Canada and whose SBT Units or PSLV Units might not otherwise qualify as capital property may be eligible to make an irrevocable election in accordance with subsection 39(4) of the Tax Act to have the SBT Units, PSLV Units and every other "Canadian security" (as defined in the Tax Act) owned by such holder deemed to be capital property in the taxation year of the election and all subsequent taxation years.

This summary assumes that each of SBT and Sprott Physical Silver Trust qualifies as a "mutual fund trust" as defined in the Tax Act, on the date hereof, and will continue to so qualify throughout the period during which SBT Unitholders hold any SBT Units or PSLV Units, and that SBT and Sprott Physical Silver Trust will jointly elect under the Tax Act for the Merger to be a "qualifying exchange" under the Tax Act.

This summary is not applicable to a SBT Unitholder that is a "financial institution", that is a "specified financial institution", that has elected to determine its Canadian tax results in a currency other than Canadian currency, or to a SBT Unitholder an interest in which is a "tax shelter investment" (as all such terms are defined in the Tax Act). Moreover, this summary does not apply to a SBT Unitholder who has entered or will enter into a "derivative forward agreement" as that term is defined in the Tax Act with respect to the SBT Units or PSLV Units. All such SBT Unitholders should consult with their own tax advisors with respect to the tax consequences of the proposed transactions.

This summary is based on the provisions of the Tax Act in force on the date hereof and counsel's understanding of the current published administrative practices and policies of the CRA. This summary takes into account all specific proposals to amend the Tax Act which have been publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof (the "Proposed Amendments") and assumes that all such Proposed Amendments will be enacted in their present form. No assurances can be given that the Proposed Amendments will be enacted in the form proposed, if at all.

This summary is not exhaustive of all possible Canadian federal tax considerations and, except for the Proposed Amendments, does not take into account or anticipate any changes in law, whether by judicial,

58

Time is of the essence. Send in your SBT Units with a completed YELLOW Letter of Transmittal to the Depositary or call your broker now to deposit.

governmental or legislative decision or action or changes in administrative practices of the CRA, nor does it take into account provincial, territorial or foreign income tax legislation or considerations.

The Canadian federal income tax consequences discussed herein are for general information only. SBT Unitholders are urged to consult their own tax advisors to determine the tax consequences to them of the Offer or the Merger (as applicable) in their particular circumstances.

Transfer of SBT Assets to Sprott Physical Silver Trust Pursuant to the Merger

The Merger will constitute a "qualifying exchange" as defined in section 132.2 of the Tax Act, thereby allowing the assets of SBT to be transferred to Sprott Physical Silver Trust for proceeds of disposition equal to the tax cost of such assets. In such circumstances, there should be no taxable income to SBT arising from the transfer. Therefore, there should be no need to make any distributions to SBT Unitholders as a result of the transfer and there should be no tax liability to SBT Unitholders resulting from the transfer.

This portion of the summary applies to a SBT Unitholder who, for purposes of the Tax Act and at all relevant times, is or is deemed to be resident in Canada.

In general, a disposition of SBT Units by an Exchange Offer Electing SBT Unitholder in exchange for PSLV Units will give rise to a capital gain (or a capital loss) equal to the amount by which the proceeds of disposition of the Tendered SBT Units, net of any reasonable costs of disposition, exceed (or are less than) the adjusted cost base of the Tendered SBT Units to the Exchange Offer Electing SBT Unitholder immediately prior to the disposition. The proceeds of disposition of the Tendered SBT Units will generally be equal to the aggregate of the fair market value of the PSLV Units received in exchange therefor. The cost for tax purposes of the PSLV Units received in exchange for Tendered SBT Units will be equal to the fair market value of such SBT Units. For the purpose of determining the adjusted cost base of such PSLV Units, the cost of such PSLV Units will be averaged with the adjusted cost base of all other PSLV Units held as capital property by such SBT Unitholder immediately before the time of the exchange.

One-half of any capital gain realized on the disposition of a SBT Unit pursuant to the Exchange Offer Election will be included in the SBT Unitholder's income as a taxable capital gain and one-half of any capital loss realized on the disposition of a SBT Unit pursuant to the Exchange Offer Election may generally be deducted only from taxable capital gains in accordance with the provisions of the Tax Act.

A SBT Unitholder that is a Canadian-controlled private corporation for the purposes of the Tax Act may be liable to pay an additional refundable 6²/3% tax in respect of any taxable capital gains realized on a disposition of such SBT Units.

In general, capital gains realized by a SBT Unitholder who is an individual may increase the SBT Unitholder's liability for alternative minimum tax.

As noted above, the Merger will constitute a "qualifying exchange" as defined in section 132.2 of the Tax Act. Accordingly, where a Merger Electing SBT Unitholder or a Non-Depositing SBT Unitholder disposes of SBT Units to SBT in exchange for PSLV Units on the redemption of SBT Units pursuant to the Merger, the SBT Unitholder's proceeds of disposition for the SBT Units disposed of, and the cost to the SBT Unitholder of the PSLV Units received in exchange therefor, will be deemed to be equal to the adjusted cost base to the SBT Unitholder of the SBT Units immediately prior to their disposition. Therefore, SBT Unitholders will not realize a capital gain (or capital loss) in respect of their SBT Units as a result of the Merger. For the purpose of determining the adjusted cost base of the PSLV Units acquired by a SBT Unitholder on such exchange, the cost of such PSLV Units will be averaged with the adjusted cost base of all other PSLV Units held as capital property by such SBT Unitholder immediately before the time of the exchange.

59

Time is of the essence. Send in your SBT Units with a completed YELLOW Letter of Transmittal to the Depositary or call your broker now to deposit.

SBT will not realize a gain or loss on the transfer of the PSLV Units to the SBT Unitholders on the redemption of SBT Units.

Subsequent to the receipt of PSLV Units for SBT Units pursuant to the Exchange Offer Election or the Merger, a former SBT Unitholder will be subject to taxation as a holder of PSLV Units. The tax treatment to the former SBT Unitholder will be substantially the same as the tax treatment to which the former SBT Unitholder was subject as a SBT Unitholder.

This portion of the summary applies to a SBT Unitholder who, for purposes of the Tax Act and at all relevant times, is not and is not deemed to be resident in Canada and does not use or hold, and is not deemed to use or hold, its SBT Units or PSLV Units acquired pursuant to the Exchange Offer Election or Merger in connection with carrying on a business in Canada (a "Non-Resident SBT Unitholder"). This summary does not apply to a Non-Resident SBT Unitholder that carries on, or is deemed to carry on, an insurance business in Canada and elsewhere and such Non-Resident SBT Unitholders should consult their own tax advisors.

A Non-Resident SBT Unitholder will not be subject to tax under the Tax Act in respect of any capital gain realized by such Non-Resident SBT Unitholder on a disposition of SBT Units pursuant to the Exchange Offer Election, unless the SBT Units constitute "taxable Canadian property" (as defined in the Tax Act) of the Non-Resident SBT Unitholder at the time of disposition and the Non-Resident SBT Unitholder is not entitled to relief under an applicable income tax treaty or convention.

As long as SBT qualifies as a mutual fund trust for purposes of the Tax Act, the SBT Units generally will not constitute taxable Canadian property of a Non-Resident SBT Unitholder, unless (a) at any time during the 60-month period immediately preceding the disposition or deemed disposition of the SBT Unit: (i) 25% or more of the issued SBT Units were owned by, or belonged to, one or any combination of (x) the Non-Resident SBT Unitholder, (y) persons with whom the Non-Resident SBT Unitholder did not deal at arm's length (within the meaning of the Tax Act) and (z) partnerships in which the Non-Resident SBT Unitholder or a person referred to in (y) holds a membership interest directly or indirectly through one or more partnerships; and (ii) more than 50% of the fair market value of the SBT Unit was derived directly or indirectly from one or any combination of: (A) real or immovable property situated in Canada; (B) Canadian resource property (as defined in the Tax Act); (C) timber resource property (as defined in the Tax Act), or (D) options in respect of, or interests in, or for civil law rights in, property described in any of (A) through (C) above, whether or not such property exists; or (b) the SBT Unit is otherwise deemed under the Tax Act to be taxable Canadian property.

If the SBT Units are taxable Canadian property to a Non-Resident SBT Unitholder, any capital gain realized on the disposition or deemed disposition of such SBT Units may not be subject to Canadian federal income tax pursuant to the terms of an applicable income tax treaty or convention between Canada and the country of residence of the Non-Resident SBT Unitholder. Non-Resident SBT Unitholders whose SBT Units are taxable Canadian property should consult their own tax advisors.

See "Residents of Canada — Holding and Disposing of PSLV Units Received for SBT Units", above.

Provided that Sprott Physical Silver Trust qualifies as a mutual fund trust for purposes of the Tax Act, or the PSLV Units are listed on a "designated stock exchange" within the meaning of the Tax Act (which currently includes the TSX and NYSE Arca), PSLV Units will be, at the time of acquisition pursuant to the Offer or the Merger, qualified investments under the Tax Act for trusts governed by registered retirement savings plans, registered retirement income funds, deferred profit sharing plans, registered education savings plans, registered disability savings plans, and tax-free savings accounts.

Notwithstanding the foregoing, the holder of a tax-free savings account or the annuitant under a registered retirement savings plan or registered retirement income fund will be subject to a penalty tax in respect of PSLV Units held by such tax-free savings account, registered retirement savings plan or registered retirement income fund, as the case may be, if such PSLV Units are a "prohibited investment" for such plans for the purposes of the Tax Act. The PSLV Units will not be a "prohibited investment" for trusts governed by a tax-free savings account, registered retirement savings plan or registered retirement income fund unless the holder of the tax-free savings account or the annuitant under the registered retirement savings plan or registered retirement income fund, as applicable: (i) does not deal at arm's length with Sprott Physical Silver Trust for purposes of the Tax Act, or (ii) has a "significant interest" as defined in the Tax Act in Sprott Physical Silver Trust. In addition, the PSLV Units will not be a "prohibited investment" if the PSLV Units are "excluded property" as defined in the Tax Act for trusts governed by a tax-free savings account, registered retirement savings plan or registered retirement income fund. Holders or annuitants should consult their own tax advisors with respect to whether PSLV Units would be prohibited investments, including with respect to whether the PSLV Units would be "excluded property" as defined in the Tax Act.

The following is a summary of the anticipated material U.S. federal income tax consequences to U.S. Holders (as defined below) that exchange SBT Units for PSLV Units pursuant to the Exchange Offer Election or the Merger Transaction, and to the ownership and disposition of the PSLV Units received pursuant to the Exchange Offer Election and the Merger Transaction. This summary addresses only U.S. Holders that hold SBT Units as "capital assets" (generally, assets held for investment purposes).

The following summary does not purport to address all U.S. federal income tax consequences that may be relevant to a U.S. Holder as a result of the exchange of SBT Units for PSLV Units pursuant to the Exchange Offer Election or the Merger Transaction or as a result of the ownership or disposition of PSLV Units received pursuant to the Exchange Offer Election and the Merger Transaction, nor does it take into account the specific circumstances of any particular holder, some of which may be subject to special tax rules (including, but not limited to, tax-exempt organizations (including private foundations), banks or other financial institutions, insurance companies, broker-dealers, traders in securities that elect to use a mark-to-market method of accounting for their securities holdings, regulated investment companies, real estate investment trusts, U.S. expatriates, holders subject to the alternative minimum tax, partnerships and other pass-through entities and investors in such entities, persons that own or are treated as owning (or owned or are treated as having owned) 10% or more of SBT's or PSLV's trust units, controlled foreign corporations, passive foreign investment companies, persons that hold a SBT or PSLV security as part of a straddle, hedge, conversion or constructive sale transaction or other integrated transaction, U.S. Holders that acquired their SBT Units through the exercise of an employee stock option or otherwise as compensation or through a tax-qualified retirement plan, and U.S. Holders whose functional currency is not the U.S. dollar).

This summary is based on the U.S. Internal Revenue Code of 1986, as amended (the "Code"), the final, temporary and proposed U.S. Treasury regulations promulgated under the Code, administrative pronouncements and rulings of the Internal Revenue Service (the "IRS") and judicial decisions, all as in effect on the date hereof, and all of which are subject to change (possibly with retroactive effect) and to differing interpretations. Except as specifically set forth below, this summary does not discuss applicable income tax

reporting requirements. This summary does not describe any state, local or non-U.S. tax law considerations, or any aspect of U.S. federal tax law other than income taxation (e.g., estate or gift tax). U.S. Holders are urged to consult their own tax advisors regarding such matters.

No legal opinion from U.S. legal counsel or ruling from the IRS has been requested, or will be obtained, regarding the U.S. federal income tax consequences of the Offer and the Merger Transaction or the ownership and disposition of the PSLV Units received pursuant to the Exchange Offer Election or the Merger Transaction. This summary is not binding on the IRS, and the IRS is not precluded from taking a position that is different from, and contrary to, the positions taken in this summary. In addition, because the authorities on which this summary is based are subject to various interpretations, the IRS and the U.S. courts could disagree with one or more of the positions taken in this summary.

As used in this summary, a "U.S. Holder" is a beneficial owner of SBT Units (or, following the completion of the Offer and the Merger Transaction, a beneficial owner of PSLV units) that is: (i) a citizen or individual resident of the United States as determined for U.S. federal income tax purposes, (ii) a corporation (or an entity taxable as a corporation) created or organized under the law of the United States, any state thereof or the District of Columbia, (iii) an estate, the income of which is subject to U.S. federal income tax without regard to its source, or (iv) a trust if (1) a court within the United States is able to exercise primary supervision over the administration of the trust, and one or more U.S. persons have the authority to control all substantial decisions of the trust, or (2) the trust has an election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

The tax treatment of a partner in a partnership (or other entity or arrangement classified as a partnership for U.S. federal income tax purposes) may depend on both the partnership's and the partner's status and the activities of the partnership. Partnerships (or other entities or arrangements classified as a partnership for U.S. federal income tax purposes) that are beneficial owners of SBT Units or PSLV Units, and their partners and other owners, are urged to consult their own tax advisors regarding the tax consequences of the Offer and the Merger Transaction and the ownership and disposition of PSLV Units received pursuant to the Exchange Offer Election or the Merger Transaction.

This summary is of a general nature only. It is not intended to constitute, and should not be construed to constitute, legal or tax advice to any particular holder. U.S. Holders are urged to consult their own tax advisors as to the tax considerations applicable to them in their particular circumstances.

U.S. Federal Income Tax Consequences of the Offer and the Merger Transaction

Exchange of SBT Units for PSLV Units Pursuant to the Exchange Offer Election and the Merger Transaction

The exchange of SBT Units for PSLV Units pursuant to the Exchange Offer Election or the Merger Transaction should be treated as a single transaction for U.S. federal income tax purposes that is intended to qualify as a Reorganization. Because the determination of whether the exchange pursuant to the Exchange Offer Election and the Merger Transaction qualifies as a Reorganization depends on the resolution of complex issues and facts, some of which will not be known until the completion of the Offer and the Merger Transaction, there can be no assurance that the exchange pursuant to the Exchange Offer Election and the Merger Transaction will qualify as a Reorganization. U.S. Holders are urged to consult their own tax advisors regarding the qualification of the exchange pursuant to the Exchange Offer Election and the Merger Transaction as a Reorganization. Neither SBT nor Sprott Physical Silver Trust (for the purposes of this Section 21 of the Circular "Certain United States Federal Income Tax Considerations", the "Trust") has sought or obtained either a ruling from the IRS or an opinion of legal counsel regarding any of the tax consequences of the exchange pursuant to the Exchange Offer Election and the Merger Transaction. Accordingly, there can be no assurance that the IRS will not challenge the treatment of the exchange pursuant to the Exchange Offer Election and the Merger Transaction as a Reorganization or that a U.S. court would uphold the status of the exchange pursuant to the Exchange Offer Election and the Merger Transaction as a Reorganization in the event of an IRS challenge. The tax consequences of the exchange pursuant to the Exchange Offer Election and the Merger Transaction qualifying as a Reorganization or as taxable transactions are discussed below.

If the exchange pursuant to the Exchange Offer Election and the Merger Transaction were treated as a Reorganization, subject to the passive foreign investment company ("PFIC") rules discussed below, a U.S. Holder that exchanged SBT Units for PSLV Units pursuant to the Exchange Offer Election or the Merger Transaction generally would not recognize gain or loss on the exchange. A U.S. Holder's initial aggregate tax basis in the PSLV Units received would be equal to the U.S. Holder's aggregate adjusted tax basis in the SBT Units exchanged, and a U.S. Holder's holding period in the PSLV Units received would include the U.S. Holder's holding period in the SBT Units exchanged. If the exchange pursuant to the Exchange Offer Election and the Merger Transaction were treated as separate transactions for U.S. federal income tax purposes, or otherwise failed to qualify as a Reorganization, subject to the PFIC rules discussed below, a U.S. Holder that, pursuant to the Exchange Offer Election or the Merger Transaction, exchanged SBT Units for PSLV Units generally would recognize gain or loss on the exchange equal to the difference, if any, between: (i) the fair market value of the PSLV Units (determined as of the Expiry Date) received in exchange for SBT Units pursuant to the Exchange Offer Election or the Merger Transaction; and (ii) the U.S. Holder's adjusted tax basis in the SBT Units exchanged therefor. In such event, a U.S. Holder's initial tax basis in its PSLV Units would equal their fair market value and the holding period of such PSLV Units would begin on the day after the Expiry Date.

As discussed below in "PFIC Rules and PFIC Status of SBT", based on public filings SBT believes that it has been a PFIC in prior taxable years and that it will be a PFIC for the current taxable year. Section 1291(f) of the Code provides that, to the extent provided in U.S. Treasury regulations, any gain on the transfer of stock in a PFIC shall be recognized notwithstanding any other provision of law. As a result, pursuant to proposed U.S. Treasury regulations promulgated under Section 1291(f) (the "Proposed Regulations"), and subject to the discussion in the next paragraph, U.S. Holders may be required to recognize gain, if any, on the exchange, even if the exchange pursuant to the Exchange Offer Election and the Merger Transaction otherwise qualifies as a Reorganization. If gain is required to be recognized as a result of Section 1291(f) of the Code and the Proposed Regulations, SBT Unitholders that are U.S. Holders and that exchange their SBT Units for PSLV Units would generally recognize any gain on such exchange equal to the difference, if any, between: (i) the fair market value of the PSLV Units (determined as of the Expiry Date) received in exchange for SBT Units pursuant to the Exchange Offer Election and the Merger Transaction; and (ii) the U.S. Holder's adjusted tax basis in the SBT Units exchanged therefor. Any gain realized on the exchange would be subject to the excess distribution rules discussed below under "PFIC Rules and PFIC Status of SBT", unless a U.S. Holder has made a mark-to-market election, also as discussed below under "PFIC Rules and PFIC Status of SBT". A U.S. Holder's initial aggregate tax basis in the PSLV Units received would be equal to the fair market value of the PSLV Units (determined as of the Expiry Date), and the U.S. Holder's holding period in the PSLV Units received would begin on the day after the Expiry Date. A U.S. Holder that has made a timely QEF Election, also discussed below under "PFIC Rules and PFIC Status of SBT", would not be subject to these gain recognition rules. U.S. Holders are urged to consult their own tax advisors regarding the potential tax consequences of SBT's PFIC status.

The Proposed Regulations provide that gain would not be recognized on a disposition of stock in a PFIC for which no election has been made, if the disposition results from a non-recognition transfer in which the stock of the PFIC is exchanged solely for stock of another corporation that qualifies as a PFIC for its taxable year that includes the day after the non-recognition transfer. As discussed below under "PFIC Status of the Trust", the Trust expects to be classified as a PFIC for its current taxable year. Accordingly, if the proposed U.S. Treasury regulations were finalized and made applicable to the Offer and the Merger Transaction (even if this occurs after the Expiry Date), the exchange of SBT Units for PSLV Units pursuant to the Exchange Offer Election or the Merger Transaction likely would not be treated as a taxable transaction pursuant to Section 1291(f) of the Code and the U.S. Treasury regulations promulgated thereunder. If finalized in their current form, these proposed U.S. Treasury regulations are proposed to be effective for transactions occurring on or after April 1, 1992. Because the proposed U.S. Treasury regulations have not yet been adopted in final form, they are not currently effective, and there is no assurance that they will be adopted in the form and with the effective date proposed. Nevertheless, the IRS has announced that, in the absence of final U.S. Treasury regulations, taxpayers may apply reasonable interpretations of the Code provisions applicable to PFICs and that it considers the rules set forth in the proposed U.S. Treasury regulations to be reasonable interpretations of those Code provisions.

The PFIC rules are complex, and the implementation of certain aspects of the PFIC rules requires the issuance of U.S. Treasury regulations which in many instances have not been promulgated and which, when promulgated, may have retroactive effect. U.S. Holders are urged to consult their own tax advisors about the potential applicability of the proposed U.S. Treasury regulations.

If the minimum tender condition is waived, so that the Tendered SBT Units are taken up and paid for but the Merger is not consummated, the exchange of SBT Units for PSLV Units pursuant to the Exchange Offer Election will be a fully taxable transaction for U.S. federal income tax purposes. Subject to the PFIC rules discussed below, a U.S. Holder that, pursuant to the Exchange Offer Election, exchanges SBT Units for PSLV Units generally would recognize gain or loss on the exchange equal to the difference, if any, between: (i) the fair market value of the PSLV Units (determined as of the Expiry Date) received in exchange for SBT Units pursuant to the Exchange Offer Election; and (ii) the U.S. Holder's adjusted tax basis in the SBT Units exchanged therefor. In such event, a U.S. Holder's initial tax basis in its PSLV Units would equal their fair market value and the holding period of such PSLV Units would begin on the day after the Expiry Date.

Certain adverse U.S. federal income tax rules could apply to U.S. Holders owning shares of a PFIC. A non-U.S. corporation generally will be classified as a PFIC for U.S. federal income tax purposes in any taxable year in which, after applying relevant look-through rules with respect to the income and assets of certain subsidiaries, either at least 75 percent of its gross income is "passive income," or, on average, at least 50 percent of the gross value (or, if elected, the adjusted tax basis) of its assets is attributable to assets that produce or are held for the production of "passive income". For this purpose, passive income generally includes, among other things, dividends, interest, certain rents and royalties, gains from the disposition of passive assets and certain net gains from commodities transactions. Based on past and current assets and operations and on assumptions about activities during the balance of the current taxable year, SBT has been a PFIC in prior taxable years and SBT has stated in public filings that it believes that it will be a PFIC for the current taxable year. However, the determination of whether or not SBT is a PFIC is based on the application of complex U.S. federal income tax rules, which are subject to differing interpretations. PFIC classification is factual in nature, generally cannot be determined until the close of the taxable year in question, and is determined annually. Consequently, there can be no assurances regarding the PFIC status of SBT for its current taxable year.

These rules would apply to a U.S. Holder that held SBT Units during any year in which SBT were a PFIC, even if SBT were not a PFIC in the year in which the U.S. Holder disposed of the SBT Units pursuant to the Exchange Offer Election or the Merger Transaction. U.S. Holders are urged to consult their tax advisors regarding the tax consequences that would arise if SBT were treated as a PFIC for any year.

Generally, if SBT were treated as a PFIC for any taxable year during which a U.S. Holder held or holds SBT Units, unless the U.S. Holder has made a mark-to-market election or a qualified electing fund election (a "QEF Election") (as described below), any gain recognized by a U.S. Holder on the exchange of SBT Units pursuant to the Exchange Offer Election or the Merger Transaction would be allocated ratably over the U.S. Holder's holding period for the SBT Units. The amounts allocated to the taxable year of the gain or "excess distribution" and to any year before SBT was a PFIC would be taxed as ordinary income in the current year. The amount allocated to each other taxable year would be subject to tax at the highest rate in effect for individuals or corporations in such taxable year, as appropriate, and an interest charge would imposed on the amount allocated to that taxable year. These rules would apply to a U.S. Holder that held SBT Units during any year in which SBT were a PFIC, even if SBT were not a PFIC in the year in which the U.S. Holder disposed of the SBT Units pursuant to the Exchange Offer Election or the Merger Transaction.

Rather than being subject to this tax regime, a U.S. Holder of stock in a PFIC generally may make:

64

Time is of the essence. Send in your SBT Units with a completed YELLOW Letter of Transmittal to the Depositary or call your broker now to deposit.

In order for a U.S. Holder to have made a QEF Election, SBT would have had to provide certain information regarding pro rata shares of its ordinary earnings and net capital gain. In order for U.S. Holders to have been able to make a mark-to-market election, the SBT Units must be treated as regularly traded on a qualified exchange or other market within the meaning of the applicable Treasury regulations.

If, contrary to its expectations, SBT were not treated as a PFIC for one or more of its taxable years, and if a U.S. Holder exchanges SBT Units pursuant to the Exchange Offer Election or the Merger Transaction that were held by such U.S. Holder only during any such time that SBT was not a PFIC ("non-PFIC Shares"), any gain or loss recognized by the U.S. Holder would be short-term capital gain or loss, unless the holding period for the non-PFIC Shares exchanged was more than 12 months at the completion of the Offer and the Merger Transaction, in which case any gain or loss recognized would be long-term capital gain or loss. Preferential tax rates for long-term capital gains are generally applicable to certain non-corporate U.S. Holders. The deduction of capital losses is subject to limitations.

U.S. Holders are urged to consult their own tax advisors with respect to SBT's status under the PFIC rules and the potential application of the PFIC rules to their particular situation, including the availability of any elections that may mitigate the application of the PFIC rules.

U.S. Federal Income Tax Consequences of the Ownership and Disposition of PSLV Units Received Pursuant to the Exchange Offer Election and the Merger Transaction

Sprott Physical Silver Trust has filed an affirmative election with the IRS to be classified as an association taxable as a corporation for U.S. federal income tax purposes.

The Trust does not anticipate making regular cash distributions to PSLV Unitholders. Subject to the PFIC discussion below, any distributions made by the Trust with respect to the PSLV Units to a U.S. Holder will generally constitute dividends, which will generally be taxable as ordinary income to the extent of the Trust's current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Distributions in excess of the Trust's earnings and profits will be treated first as a nontaxable return of capital to the extent of the U.S. Holder's tax basis in the PSLV Units on a dollar-for-dollar basis and thereafter as gain from the disposition of PSLV Units. Since the Trust will be a PFIC, as described below, dividends paid on the PSLV Units to a U.S. Holder that is an individual, trust or estate (a "U.S. Individual Holder") will generally not be treated as "qualified dividend income" that is taxable to U.S. Individual Holders at preferential tax rates. Any dividends generally will be treated as foreign-source income for U.S. foreign tax credit limitation purposes.

A U.S. Holder may have PSLV Units redeemed for cash or physical silver bullion. Under Section 302 of the Code, a U.S. Holder generally will be treated as having sold PSLV Units (rather than having received a distribution on PSLV Units) upon the redemption of PSLV Units if the redemption completely terminates or significantly reduces the U.S. Holder's interest in the Trust. In such case, the redemption will be treated as described in the relevant section below depending on whether the U.S. Holder makes a QEF Election, a mark-to-market election or makes no election and therefore is subject to the Default PFIC Regime (as defined below).

Certain adverse consequences could apply to a U.S. Holder if the Trust is treated as a PFIC under the rules described above in "PFIC Rules and PFIC Status of SBT" for any taxable year during which the U.S. Holder holds PSLV Units. The Trust is currently classified as a PFIC, and the Trust believes that it will continue to be classified as a PFIC after the completion of the Offer and the Merger Transaction. The determination of whether or not the Trust is a PFIC is based on the application of complex U.S. federal income tax rules, which are subject to differing interpretations. PFIC classification is factual in nature, generally cannot be determined until the close of the taxable year in question, and is determined annually. Consequently, there can be no assurances regarding the PFIC status of the Trust for its current or any future taxable year.

The implications of PFIC status and applicable elections are discussed in greater detail above in "PFIC Rules and PFIC Status of SBT". The Trust intends to provide the information necessary for U.S. Holders to make a QEF Election with respect to PSLV Units in the event that the Trust is classified as a PFIC. U.S. Holders are urged to consult their own tax advisors with respect to the Trust's status under the PFIC rules and the potential application of the PFIC rules to their particular situation, including the availability of any elections (including a mark-to-market election) that may mitigate the application of the PFIC rules.

Making the Election. A U.S. Holder would make a QEF Election with respect to any year that the Trust is a PFIC by filing IRS Form 8621 with its U.S. federal income tax return. The Trust intends to annually provide each U.S. Holder with all necessary information in order to make and maintain a QEF Election. A U.S. Holder that makes a QEF Election for the first taxable year in which it owns PSLV Units (an "Electing Holder" and, if also a U.S. Individual Holder, a "Non-Corporate Electing Holder") will not be subject to the Default PFIC Regime for any taxable year. A U.S. Holder that does not make a timely QEF Election would be subject to the Default PFIC Regime for taxable years during its holding period in which a QEF Election was not in effect, unless such U.S. Holder makes a special "purging" election. A U.S. Holder that does not make a timely QEF Election is encouraged to consult such U.S. Holder's tax advisor regarding the availability of such purging election.

Current Taxation and Dividends. An Electing Holder must report each year for U.S. federal income tax purposes its pro rata share of the Trust's ordinary earnings and net capital gain, if any, for the Trust's taxable year that ends with or within the taxable year of the Electing Holder, regardless of whether or not distributions were received from the Trust by the Electing Holder. A Non-Corporate Electing Holder's pro rata share of the Trust's net capital gain generally will be taxable at a maximum rate of 28% under current law to the extent attributable to sales of physical silver bullion by the Trust if the Trust has held the silver bullion for more than one year. Otherwise, such gain generally will be treated as ordinary income.

If any holder redeems its PSLV Units for physical silver bullion (regardless of whether the holder requesting redemption is a U.S. Holder or an Electing Holder), the Trust will be treated as if it sold physical silver bullion for its fair market value in order to redeem the holder's PSLV Units. As a result, any Electing Holder will be required to include currently in income its pro rata share of the Trust's gain from such deemed disposition (taxable to a Non-Corporate Electing Holder at a maximum rate of 28% under current law if the Trust has held the physical silver bullion for more than one year) even though the deemed disposition by the Trust is not attributable to any action on the Electing Holder's part. If any holder redeems PSLV Units for cash and the Trust sells physical silver bullion to fund the redemption (regardless of whether the holder requesting redemption is a U.S. Holder or an Electing Holder), an Electing Holder similarly will include in income its pro rata share of the Trust's gain from the sale of the physical silver bullion, which will be taxable as described above even though the Trust's sale of physical silver bullion is not attributable to any action on the Electing Holder's part. The Trust expects to manage dispositions of physical silver bullion to minimize the amount of gain it recognizes in connection with redemptions. An Electing Holder's adjusted tax basis in the PSLV Units will be increased to reflect any amounts included currently in income under the QEF rules. Distributions of earnings and profits that had been previously included in income will result in a corresponding reduction in the adjusted tax basis in the PSLV Units and will not be taxed again once distributed. Any other distributions generally will be treated as discussed above under "Distributions on PSLV Units".

Income inclusions under the QEF rules described above generally should be treated as foreign-source income for U.S. foreign tax credit limitation purposes, but Electing Holders are urged to consult their tax advisors in this regard.

Sale, Exchange or Other Disposition. An Electing Holder will generally recognize capital gain or loss on the sale, exchange, or other disposition of the PSLV Units in an amount equal to the excess of the amount realized on such disposition over the Electing Holder's adjusted tax basis in the PSLV Units. Such gain or loss will be treated as long-term capital gain or loss if the Electing Holder's holding period in the PSLV Units is greater than one year at the time of the sale, exchange or other disposition. Long-term capital gains of U.S. Individual Holders currently are taxable at a maximum rate of 15%, or 20% in the case of certain high

66

income Non-Corporate Electing Holders. An Electing Holder's ability to deduct capital losses is subject to certain limitations. Any gain or loss generally will be treated as U.S.-source gain or loss for U.S. foreign tax credit limitation purposes.

An Electing Holder that redeems its trust units will be required to include currently in income its pro rata share of the Trust's gain from the deemed or actual disposition of physical silver bullion, as described above, which will be taxable to a Non-Corporate Electing Holder at a maximum rate of 28% under current law if the Trust has held the physical silver bullion for more than one year. The Electing Holder's adjusted tax basis in the PSLV Units will be increased to reflect such gain that is included in income. The Electing Holder will further recognize capital gain or loss on the redemption in an amount equal to the excess of the fair market value of the physical silver bullion or cash received upon redemption over the Electing Holder's adjusted tax basis in the PSLV Units. Such gain or loss will be treated as described in the preceding paragraph.

Making the Election. Alternatively, if, as is anticipated, the PSLV Units are treated as "marketable stock", a U.S. Holder would be allowed to make a mark-to-market election with respect to the PSLV Units, provided the U.S. Holder completes and files IRS Form 8621 in accordance with the relevant instructions and related Treasury regulations. The PSLV Units will be treated as marketable stock for this purpose if they are regularly traded on a qualified exchange or other market. The PSLV Units will be regularly traded on a qualified exchange or other market for any calendar year during which they are traded (other than in de minimis quantities) on at least 15 days during each calendar quarter. A qualified exchange or other market means either a U.S. national securities exchange that is registered with the SEC, the NASDAQ, or a foreign securities exchange that is regulated or supervised by a governmental authority of the country in which the market is located and which satisfies certain regulatory and other requirements. The Trust believes that both the TSX and NYSE Arca should be treated as a qualified exchange or other market for this purpose.

Current Taxation and Dividends. If the mark-to-market election is made, the U.S. Holder generally would include as ordinary income in each taxable year the excess, if any, of the fair market value of the PSLV Units at the end of the taxable year over such U.S. Holder's adjusted tax basis in the PSLV Units. The U.S. Holder would also be permitted an ordinary loss in respect of the excess, if any, of the U.S. Holder's adjusted tax basis in the PSLV Units over their fair market value at the end of the taxable year, but only to the extent of the net amount previously included in income as a result of the mark-to-market election. Any income inclusion or loss under the preceding rules should be treated as gain or loss from the sale of PSLV Units for purposes of determining the source of the income or loss. Accordingly, any such gain or loss generally should be treated as U.S.-source income or loss for U.S. foreign tax credit limitation purposes. A U.S. Holder's tax basis in its PSLV Units would be adjusted to reflect any such income or loss amount. Distributions by the Trust to a U.S. Holder that has made a mark-to-market election generally will be treated as discussed above under "Distributions on PSLV Units".

Sale, Exchange or Other Disposition. Gain realized on the sale, exchange, redemption or other disposition of the PSLV Units would be treated as ordinary income, and any loss realized on the sale, exchange, redemption or other disposition of the PSLV Units would be treated as ordinary loss to the extent that such loss does not exceed the net mark-to-market gains previously included by the U.S. Holder. Any loss in excess of such previous inclusions would be treated as a capital loss by the U.S. Holder. A U.S. Holder's ability to deduct capital losses is subject to certain limitations. Any such gain or loss generally should be treated as U.S.-source income or loss for U.S. foreign tax credit limitation purposes.

Taxation of U.S. Holders Not Making a Timely QEF or Mark-to-Market Election

Finally, a U.S. Holder that does not make either a QEF Election or a mark-to-market election for that year (a "Non-Electing Holder") would be subject to special rules (the "Default PFIC Regime") with respect to: (1) any excess distribution (i.e., the portion of any distributions received by the Non-Electing Holder on the PSLV Units in a taxable year in excess of 125% of the average annual distributions received by the Non-Electing Holder in the three preceding taxable years, or, if shorter, the Non-Electing Holder's holding period for the PSLV Units); and (2) any gain realized on the sale, exchange, redemption or other disposition of the PSLV Units.

67

Time is of the essence. Send in your SBT Units with a completed YELLOW Letter of Transmittal to the Depositary or call your broker now to deposit.

Under the Default PFIC Regime: (i) the excess distribution or gain would be allocated ratably over the Non-Electing Holder's aggregate holding period for the PSLV Units; (ii) the amount allocated to the current taxable year and any taxable year before the Trust became a PFIC would be taxed as ordinary income; and (iii) the amount allocated to each of the previous taxable years would be subject to tax at the highest rate of tax in effect for the applicable class of taxpayer for that year, and an interest charge for the deemed tax deferral benefit would be imposed with respect to the resulting tax attributable to each such other taxable year.

Any distributions other than "excess distributions" by the Trust to a Non-Electing Holder will be treated as discussed above under "Distributions on PSLV Units".

These penalties would not apply to a pension or profit sharing trust or other tax-exempt organization that did not borrow funds or otherwise utilize leverage in connection with its acquisition of the PSLV Units. If a Non-Electing Holder that is an individual dies while owning the PSLV Units, such Non-Electing Holder's successor generally would not receive a step-up in tax basis with respect to the PSLV Units.

U.S. Holders that are individuals, estates or trusts, whose income exceeds certain thresholds, generally will be subject to an additional 3.8% tax on net investment income, including dividends on and capital gains from a sale or other taxable disposition of PSLV Units, subject to certain limitations and exceptions. U.S. Holders are urged to consult their own tax advisors regarding the applicability to them of this tax on net investment income.

If any dividends paid to U.S. Holders of PSLV Units are paid in Canadian currency, the amount includible in gross income will be the U.S. dollar value of such dividend, calculated by reference to the exchange rate in effect on the date of actual or constructive receipt of the payment, regardless of whether the payment is actually converted into U.S. dollars. Canadian currency received by a U.S. Holder will have a tax basis equal to its U.S. dollar value at the time such currency is received. If such Canadian currency is converted into U.S. dollars on the date of receipt, the U.S. Holder generally should not be required to recognize foreign currency gain or loss. The amount of gain or loss recognized on a subsequent sale or other disposition of such Canadian currency will equal the difference between (i) the amount of U.S. dollars, or the fair market value in U.S. dollars of other property received, in such sale or other disposition, and (ii) the U.S. Holder's tax basis in such Canadian currency. Any such gain or loss generally will be treated as U.S.-source ordinary income or loss.

A U.S. Holder that pays (whether directly or through withholding) Canadian income tax in connection with the Offer and the Merger Transaction or in connection with the ownership or disposition of PSLV Units may be entitled, at the election of such U.S. Holder, to receive either a deduction or a credit for such Canadian income tax paid. Generally, a credit will reduce a U.S. Holder's U.S. federal income tax liability on a dollar-for-dollar basis, whereas a deduction will reduce a U.S. Holder's income subject to U.S. federal income tax. This election is made on an annual basis and applies to all foreign taxes paid (whether directly or through withholding) by a U.S. Holder during that taxable year.

The rules governing the foreign tax credit are complex and subject to a number of significant limitations, among which is the general limitation that the credit cannot exceed the proportionate share of the U.S. Holder's U.S. federal income tax liability that such U.S. Holder's "foreign source" income bears to the U.S. Holder's worldwide taxable income. A U.S. Holder's gain from the disposition of SBT Units or PSLV Units generally will be treated as U.S.-source income for purposes of U.S. foreign tax credit limitations unless the gain is subject to tax in Canada and treated instead as foreign source under the provisions of the Canada-U.S. Tax Convention. Dividends paid on PSLV Units generally will be treated as foreign source income for U.S. foreign tax credit limitation purposes. U.S. Holders are urged to consult their own tax advisors regarding the availability of the foreign tax credit under their particular circumstances.

Certain U.S. Holders are required to report information relating to an interest in the PSLV Units, subject to certain exceptions (including an exception for PSLV Units held in accounts maintained by financial institutions). U.S. Holders are urged to consult their own tax advisors regarding their information reporting obligations, if any, with respect to their ownership and disposition of the PSLV Units received pursuant to the Exchange Offer Election or the Merger Transaction.

successful completion of the Offer and the Merger Transaction is subject to certain risks, including as set forth below. Such risks may not be the only risks facing Sprott Physical Silver Trust. Additional risks and uncertainties not presently known may also materially and adversely affect the business, operations, financial condition or prospects of Sprott Physical Silver Trust.

The issuance of PSLV Units as consideration under the Offer could adversely affect the market price of PSLV Units after the take up of SBT Units under the Offer and completion of the Merger Transaction.

If all of the SBT Units are tendered to the Offer, additional PSLV Units will be available for trading in the public market. The overall increase in the number of PSLV Units may lead to sales of such units or the perception that such sales may occur, either of which may adversely affect the market for, and the market price of, PSLV Units. The perceived risk of substantial sales of PSLV Units, as well as any actual sales of such PSLV Units in the public market, could adversely affect the market price of the PSLV Units.

The Offeror has not verified the reliability of the information regarding SBT included in, or which may have been omitted from, the Offer and Circular.

All information regarding SBT contained in the Offer and Circular, including SBT financial information and all pro forma financial information reflecting the pro forma effects of a combination of certain of SBT's assets and liabilities and Sprott Physical Silver Trust that are derived in part from SBT's financial information, has been derived from SBT's public disclosure. Although the Offeror has no reason to doubt the accuracy or completeness of SBT's public disclosure, any inaccuracy or material omission in SBT's public disclosure, including the information about or relating to SBT and its business, prospects, condition (financial or otherwise) and assets contained in the Offer and Circular, could result in unanticipated liabilities or expenses, increase the cost of integrating the assets of the SBT with those of Sprott Physical Silver Trust or adversely affect the operational plans or prospects of Sprott Physical Silver Trust and its results of operations and financial condition.

The Offer is conditional upon, among other things, the receipt of consents and approvals from governments and regulatory authorities that could delay completion of the Offer and the Merger Transaction.

The Offer is conditional upon, among other things, the Offeror having obtained all government or regulatory consents, authorizations, waivers, permits, reviews, orders, rulings, decisions, approvals, exemptions and the expiration of any applicable waiting periods (including but not limited to those of any stock exchange or other Securities Regulatory Authorities) that are necessary or desirable to complete the Offer and the Merger Transaction and to issue and list on the TSX and NYSE Arca the PSLV Units to be issued pursuant to the Offer and the Merger Transaction on terms and conditions reasonably satisfactory to the Offeror. A substantial delay in obtaining satisfactory approvals or the imposition of unfavourable terms or conditions in the approvals could have an adverse effect on the business, financial condition or results of operations of Sprott Physical Silver Trust.

U.S. Holders generally will not be entitled to recognize any loss on the exchange of SBT Units

U.S. Holders generally will not be entitled to recognize any loss on the exchange of SBT Units pursuant to the Exchange Offer Election or the Merger Transaction. SBT Unitholders are strongly advised to review the summary contained under the heading "Certain United States Federal Income Tax Considerations" and to consult their own tax advisors for advice with respect to their own particular circumstances.

The value of the PSLV Units relates directly to the value of the silver held by Sprott Physical Silver Trust, and fluctuations in the price of silver could materially adversely affect an investment in the PSLV Units.

The principal factors affecting the value of the PSLV Units are factors that affect the price of silver. Silver bullion is tradable internationally and its price is generally quoted in U.S. dollars. The price of the PSLV Units depends on, and typically fluctuates with, the price fluctuations of silver. The price of silver may be affected at

70

any time by many international, economic, monetary and political factors, many of which are unpredictable. These factors include, without limitation:

Changing tax, royalty, land and mineral rights ownership and leasing regulations in silver producing countries can also have an impact on market functions and expectations for future silver supply. This can affect both share prices of silver mining companies and the relative prices of other commodities, which are both factors that may affect investor decisions in respect of investing in silver.

An investment in Sprott Physical Silver Trust will yield long-term gains only if the value of silver increases in an amount in excess of Sprott Physical Silver Trust's expenses.

Sprott Physical Silver Trust does not actively trade silver to take advantage of short-term market fluctuations in the price of silver or generate other income. Accordingly, Sprott Physical Silver Trust's long-term performance is dependent on the long-term performance of the price of silver. As a result, an investment in Sprott Physical Silver Trust will yield long-term gains only if the value of silver increases in an amount in excess of Sprott Physical Silver Trust's expenses.

A redemption of PSLV Units for cash will yield a lesser amount than selling the PSLV Units on NYSE Arca or the TSX, if such a sale is possible.

Because the cash redemption value of the PSLV Units is based on 95% of the lesser of: (i) the volume-weighted average trading price of the PSLV Units traded on NYSE Arca or, if trading has been suspended on NYSE Arca, the volume-weighted average trading price of the PSLV Units traded on the TSX, for the last five days on which the respective exchange is open for trading for the month in which the redemption request is processed and (ii) the NAV of the redeemed PSLV Units as of 4:00 p.m. (Toronto time) on the last day of the month on which NYSE Arca is open for trading for the month in which the redemption request is processed, redeeming PSLV Units for cash will generally yield a lesser amount than selling PSLV Units on NYSE Arca or the TSX, assuming such a sale is possible. You should consider the manner in which the cash redemption value is determined before exercising your right to redeem your PSLV Units for cash.

If a PSLV Unitholder redeems PSLV Units for physical silver bullion and requests to have the silver delivered to a destination other than an institution authorized to accept and hold London Good Delivery silver bars, the physical silver bullion will no longer be deemed London Good Delivery once it has been delivered.

London Good Delivery bars have the advantage that a purchaser generally will accept such bars as consisting of the indicated number of troy ounces of at least .995 fine silver without assaying or otherwise testing them. This provides London Good Delivery bars with added liquidity as a sale of such bars can be completed more easily than the sale of physical silver bullion that is not London Good Delivery. Sprott Physical Silver Trust will only purchase London Good Delivery bars, and the physical silver bullion owned by Sprott Physical Silver Trust will retain its status as London Good Delivery bars while it is stored at the Mint. If a PSLV Unitholder redeems units for physical silver bullion and has the silver delivered to an institution authorized to accept and hold London Good Delivery silver bars through an armored transportation service carrier that is eligible to transport London Good Delivery silver bars, it is likely that the silver will retain its London Good Delivery status while in the custody of that institution. However, if the redeeming PSLV Unitholder instructs that silver be delivered to a destination other than such an institution, the physical silver bullion delivered to the PSLV

71

Unitholder will no longer be deemed London Good Delivery once it has been delivered pursuant to the redeeming PSLV Unitholder's delivery instructions, which may make a future sale of such silver more difficult.

The issuance of PSLV Units, in exchange for the acquisition of SBT, will be accounted for as a capital transaction. The transaction will not qualify as a business combination under IFRS 3. Sprott Physical Silver Trust's accounting policies after the Merger Transaction are expected to be consistent with Sprott Physical Silver Trust's current accounting policies and no other material consequences are expected to occur.

Securities legislation in the provinces and territories of Canada provides security holders of SBT with, in addition to any other rights they may have at law, one or more rights of rescission, price revision or to damages, if there is a misrepresentation in a circular or a notice that is required to be delivered to those security holders. However, such rights must be exercised within prescribed time limits. SBT Unitholders should refer to the applicable provisions of the securities legislation of their province or territory for particulars of those rights or consult with a lawyer.

Other than compensation (which would equal approximately Cdn.$300,000 if the Offer is successful) payable to Kingsdale Shareholder Services as the Information Agent, the Offeror has not agreed to pay any fees or commission to any stockbroker, dealer or other person for soliciting tenders or deposits of SBT Units under the Offer; provided that the Offeror may make arrangements with soliciting dealers, dealer managers or information agents, either within or outside of Canada for customary compensation during the Offer if it considers it appropriate to do so.

The Offeror has retained Kingsdale Shareholder Services to act as Depositary for the Offer. The Depositary: (i) will receive deposits of certificates representing SBT Units and accompanying Letters of Transmittal at the offices specified in the Letters of Transmittal; (ii) will be responsible for giving certain notices, if required, and disbursing payment for SBT Units purchased by the Offeror under the Offer and for all SBT Units to be redeemed as part of the Merger Transaction; and (iii) will assist with SBT Unitholder identification and communication in respect of the Offer. The Depositary will receive reasonable and customary compensation from the Offeror for its services in connection with its role as depositary and information agent for the Offer, will be reimbursed for certain out-of-pocket expenses and will be indemnified against certain liabilities, including liabilities under applicable securities laws.

The Offeror has retained Kingsdale Shareholder Services to as its information agent in connection with the Offer.

The opinion contained under Section 20 of the Circular, "Certain Canadian Federal Income Tax Considerations" has been provided by Stikeman Elliott LLP. As at the date hereof, the partners and associates of Stikeman Elliott LLP, as a group, beneficially own, directly or indirectly, less than 1% of any class of Sprott Physical Silver Trust's issued and outstanding securities.

COMPARISON OF CANADIAN SECURITIES REGULATORY REGIME
FOR INVESTMENT FUNDS AND PUBLIC COMPANIES

The continuous disclosure obligations for an investment fund are governed primarily by National Instrument 81-106 — Investment Fund Continuous Disclosure ("NI 81-106"), while the continuous disclosure obligations for a public company are governed primarily by National Instrument 51-102 — Continuous Disclosure Requirements ("NI 51-102"). While the two continuous disclosure regimes are similar and both require periodic disclosure to investors on an annual and interim basis, there are a number of specific key differences as outlined in the table below.

	Investment Fund Regime	Public Company Regime⁽¹⁾



Continuous Disclosure Comparison

1. Key Legislation	NI 81-106	NI 51-102

2. Focus of disclosure	Investor returns and portfolio management; investor focused data (e.g. net asset value ("NAV") and management expense ratio ("MER")).	Financial condition of revenue-generating operations. Focus is on the operational level. No prescribed framework for the reporting of investment portfolio performance and NAV, the way that the investment fund regime provides.

3. NAV and Management Expense Ratio calculations	An investment fund must, upon calculating the NAV of the investment fund under this section, make the following information available to the public at no cost: • the net asset value of the investment fund; and • the net asset value per security of the investment fund unless the investment fund is a scholarship plan. An investment fund may also disclose its calculation of Management Expense Ratio as set out in NI 81-106. Reference: Parts 14 and 15 of NI 81-106	The concept of calculating NAV and MER is not found in the Public Company Regime.

	Investment Fund Regime	Public Company Regime⁽¹⁾



4. Corporate Governance Requirements	Investment funds must have a manager and an independent review committee, which are subject to prescribed criteria and disclosure obligations. Reference: National Instrument 81-107 — Independent Review Committee for Investment Funds and Form 81-101F2 — Contents of Annual Information Form ("NI 81-101F2")	A public company has broad-based corporate governance requirements applicable to all aspects of governance. A public company must, at a minimum, have an independent audit committee. In addition, a public company should either have a compensation committee and a nominating committee, or describe what steps the board takes to encourage an objective compensation and nomination process if it does not have the relevant committees. A public company must make prescribed disclosure regarding its committees and corporate governance practices in its annual information form. Reference: National Instrument 52-110 — Audit Committees, National Instrument 58-101 — Disclosure of Corporate Governance Practices and National Policy 58-201 — Corporate Governance Guidelines.

5. Changes to the Fund	Investment funds shall be required to provide unitholders with a vote on certain fundamental changes, including: • changes to the calculation of certain fees or expenses • change of manager • change of fundamental investment objectives • certain reorganizations or sale of the assets of an investment fund • Reference: National Instrument 81-102 — Investment Funds	There is no corresponding requirement for a public company to provide securityholders a vote on fundamental changes, unless required under applicable corporate law or exchange requirements.

6. Audit and Accounting Standards	Acceptable Accounting Principles: IFRS Acceptable Auditing Standards: Canadian Generally Accepted Auditing Standards ("GAAS")	Acceptable Accounting Principles: IFRS. Acceptable Auditing Standards: GAAS.

A MRFP includes • management discussion of fund performance; • financial highlights; • past performance; • summary of investment portfolio; and • other material information.	Filing Deadline: Within 90 days after the public company's financial year-end. A public company needs to file, together with the annual financial statements, an annual Management Discussion & Analysis ("MD&A"), setting out a detailed discussion of the company's operational performance. Overall focus: The MD&A focuses primarily on a public company's operational level results and financial condition and compares trends over the last 8 quarters. A MD&A requires a disclosure of diversified, specific information about the company's operation and performance, including: • prescribed financial data derived from current annual financial statements and quarterly reports for each of the last 8 quarters, discussion of factors that have caused period to period variations;
