Share,
on any matter, question, proposal or proposition whatsoever that may properly come before the stockholders of US Gold at a US Gold Meeting or in connection with a US Gold Consent. The Voting
Rights shall be and remain vested in and exercised by the Trustee subject to the terms of this Agreement. Subject to Section 6.15 hereof, the Trustee shall exercise the Voting Rights only on
the basis of instructions received pursuant to this ARTICLE 4 from Beneficiaries entitled to instruct the Trustee as to the voting thereof at the time at which the US Gold Consent is sought or the US
Gold Meeting is held. To the extent that no instructions are received from a Beneficiary with respect to the Voting Rights to which such Beneficiary is entitled, the Trustee shall not exercise or

        With respect to all meetings of stockholders of US Gold at which holders of shares of US Gold Common Stock are entitled to vote (each, a
"US Gold Meeting") and with respect to all written consents sought from the holders of shares of US Gold Common Stock (a "US
Gold Consent"), each Beneficiary shall be entitled to instruct the Trustee to cast and exercise, in the manner instructed, a number of votes equal to the Equivalent Vote Amount
for each Exchangeable Share owned of record by such Beneficiary at the close of business on the record date established by US Gold or by applicable Law for such US Gold Meeting or US Gold Consent, as
the case may be (the "Beneficiary Votes"), in respect of each matter, question, proposal or proposition to be voted on at such US Gold Meeting or to be
consented to in connection with such US Gold Consent. 

4.3   Mailings to Shareholders  

	(1)
	With
respect to each US Gold Meeting and US Gold Consent, the Trustee will mail or cause to be mailed (or otherwise communicate in the same manner as US
Gold utilizes in communications to holders of shares of US Gold Common Stock, subject to applicable regulatory requirements and to the Trustee being advised in writing of such manner and provided that
such manner of communications is reasonably available to the Trustee) to each of the Beneficiaries named in the List, on the same day as the mailing or notice (or other communication) with respect
thereto is commenced by US Gold to its stockholders:

	(a)
	a
copy of such notice, together with any related materials, including any proxy or information statement or listing particulars, to be provided to
shareholders of US Gold but excluding proxies to vote shares of US Gold Common Stock;

	(b)
	a
statement that such Beneficiary is entitled to instruct the Trustee as to the exercise of the Beneficiary Votes with respect to such US Gold Meeting or US
Gold Consent, as the case may be, or, pursuant and subject to Section 4.7, to attend such US Gold Meeting and to exercise personally the Beneficiary Votes thereat;

	(c)
	a
statement as to the manner in which such instructions may be given to the Trustee, including an express indication that instructions may be given to the

	(f)
	a
statement of: (i) the time and date by which such instructions must be received by the Trustee in order to be binding upon it, which in the case of
a US Gold Meeting shall not be later than the close of business on the Business Day immediately prior to the date by which US Gold has required proxies to be deposited for such meeting; and
(ii) of the method for revoking or amending such instructions.

	(2)
	The
materials referred to in this Section 4.3 are to be provided to the Trustee by US Gold, and the materials referred to in
Sections 4.3(1)(b), 4.3(1)(c), 4.3(1)(d), 4.3(1)(e) and 4.3(1)(f) shall (if reasonably practicable to do so) be subject to reasonable comment by the Trustee in a timely manner; provided,
however, that the Trustee shall have no obligation to review such materials. Subject to the foregoing, US Gold shall ensure that the materials to be provided to the Trustee are provided in sufficient
time to permit the Trustee to comment as aforesaid and to send all materials to each Beneficiary at the same time as such materials are first sent to holders of shares of US Gold Common Stock. US Gold
agrees not to communicate with holders of shares of US Gold Common Stock with respect to the materials referred to in this Section 4.3 otherwise than by mail unless such method of communication
is also reasonably available to the Trustee for communication with the Beneficiaries. Notwithstanding the foregoing, US Gold may at its option exercise the duties of the Trustee to deliver copies of
all materials to each Beneficiary as required by this Section 4.3 so long as in each case US Gold delivers a certificate to the Trustee stating that US Gold has undertaken to perform the
obligations of the Trustee set forth in this Section 4.3.

	(3)
	For
the purpose of determining Beneficiary Votes to which a Beneficiary is entitled in respect of any US Gold Meeting or US Gold Consent, the number of
Exchangeable Shares owned of record by the Beneficiary shall be determined at the close of business on the record date established by US Gold or by applicable Law for purposes of determining
shareholders entitled to vote at such US Gold Meeting. US Gold will notify the Trustee of any decision of the board of directors of US Gold with respect to the calling of any US Gold Meeting and shall
provide all necessary information and materials to the Trustee in each case promptly and in any event in sufficient time to enable the Trustee to perform its obligations contemplated by this
Section 4.3. 

4.4   Copies of Shareholder Information  

        US Gold will deliver to the Trustee copies of all proxy materials (including notices of US Gold Meetings but excluding proxies to vote shares of US Gold Common
Stock), information statements, reports (including all interim and annual financial statements) and other written communications that, in each case, are to be distributed by US Gold from time to time
to holders of shares of US Gold Common Stock in sufficient quantities and in sufficient time so as to enable the Trustee to send or cause to be sent those materials to each Beneficiary at the same
time as such materials are first sent to holders of shares of US Gold Common Stock. The Trustee will mail or otherwise send, or cause to be mailed or otherwise sent, to each Beneficiary, at the
expense of US Gold, copies of all such materials (and all materials specifically directed to the Beneficiaries or to the Trustee for the benefit of the Beneficiaries by US Gold) received by the
Trustee from US Gold contemporaneously with the sending of such materials to holders of shares of US Gold Common Stock. The Trustee will also make available for inspection by any Beneficiary at the

Common Stock; or

        Notwithstanding
the foregoing, US Gold at its option may exercise the duties of Trustee to deliver copies of all materials to each Beneficiary as required by this Section 4.4 so
long as in each case US Gold delivers a certificate to the Trustee stating that US Gold has undertaken to perform the obligations set forth in this Section 4.4. 

4.5   Other Materials  

        As soon as reasonably practicable after receipt by US Gold or stockholders of US Gold (if such receipt is known by US Gold) of any material sent or given by or on
behalf of a third party to holders of shares of US Gold Common Stock generally, including dissident proxy and information circulars (and related information and material) and take-over
bid, tender offer and securities exchange take-over bid circulars (and related information and material), provided such material has not been sent to the Beneficiaries by or on behalf of
such third party, US Gold shall use its reasonable efforts to obtain and deliver to the Trustee copies thereof in sufficient quantities so as to enable the Trustee to forward or cause to be forwarded
such material (unless the same has been provided directly to Beneficiaries by such third party) to each Beneficiary as soon as possible thereafter. As soon as reasonably practicable after receipt
thereof, the Trustee will mail or otherwise send, or cause to be mailed or otherwise sent, to each Beneficiary, at the expense of US Gold, copies of all such materials received by the Trustee from US
Gold. The Trustee will also make available for inspection by any Beneficiary at the Trustee's principal office(s) in Toronto, Ontario or Calgary, Alberta copies of all such materials. Notwithstanding
the foregoing, US Gold at its option may exercise the duties of Trustee to deliver copies of all materials to each Beneficiary as required by this Section 4.5 so long as in each case US Gold
delivers a certificate to the Trustee stating that US Gold has undertaken to perform the obligations set forth in this Section 4.5. 

4.6   List of Persons Entitled To Vote  

        Exchangeco shall:    (a) prior to each annual, general and special US Gold Meeting or the seeking of any US Gold Consent; and

Gold or pursuant to applicable Law for determining the holders of shares of US Gold Common Stock entitled to receive notice of and/or to vote at such US Gold Meeting or to give consent in connection
with a US Gold Consent. Each such List shall be delivered to the Trustee promptly after receipt by Exchangeco of such request or the record date for such meeting or seeking of consent, as the case may
be, and, in any event, within sufficient time as to enable the Trustee to perform its obligations under this Agreement. US Gold agrees to give Exchangeco written notice (with a copy to the Trustee) of
the calling of any US Gold Meeting or the seeking of any US Gold Consent, together with the record date therefor, sufficiently prior to the date of the calling of such meeting or seeking such consent
so as to enable Exchangeco to perform its obligations under this Section 4.6.

in the notice sent or caused to be sent by the Trustee to the Beneficiary pursuant to Section 4.3.

	(2)

Trustee shall cause such representatives who are empowered by it to sign and deliver, on behalf of the Trustee, proxies for Voting Rights enabling a
Beneficiary to attend each US Gold Meeting. Upon submission by a Beneficiary (or its designee) named in the List prepared in connection with the relevant meeting of identification satisfactory to the
Trustee's representative, and at the Beneficiary's request, such representative shall sign and deliver to such Beneficiary (or its designee) a proxy to exercise personally the Beneficiary Votes as to
which such Beneficiary is otherwise entitled hereunder to direct the vote, if such Beneficiary either: (i) has not previously given the Trustee instructions pursuant to Section 4.2 in
respect of such meeting; or (ii) submits to such representative written revocation of any such previous instructions. At such meeting, the Beneficiary (or its designee) exercising such
Beneficiary Votes shall have the same rights in respect of such Beneficiary Votes as the Trustee to speak at the meeting in respect of any matter, question, proposal or proposition, to vote by way of
ballot at the meeting in respect of any matter, question, proposal or proposition, and to vote at such meeting by way of a show of hands in respect of any matter, question or proposition.

4.11 Disclosure of Interest in Exchangeable Shares  

        The Trustee or Exchangeco shall be entitled to require any Beneficiary or any Person whom the Trustee or Exchangeco knows or has reasonable cause to believe holds
any interest whatsoever in an Exchangeable Share: (a) to confirm that fact; or (b) to give such details as to whom has an interest in such Exchangeable Share, in each case as would be
required (if the Exchangeable Shares were a class of "equity securities" of Exchangeco) under Section 102.1 of the Securities Act (Ontario), as
amended
from time to time, or as would be required under the articles of US Gold or any Laws or regulations, or pursuant to the rules or regulations of any regulatory authority, of Canada or the United States
as if, and only to the extent that, the Exchangeable Shares were shares of US Gold Common Stock. 

        If

	(b)
	except
as specifically authorized by this Agreement, have no power or authority to exercise or otherwise deal in or with the Automatic Exchange Right or the
Exchange Right, and the Trustee shall not exercise any such rights for any purpose other than the purposes for which this Trust is created pursuant to this Agreement. 

5.2   Legended Share Certificates  

        Exchangeco will cause each certificate representing Exchangeable Shares to bear an appropriate legend notifying the Beneficiaries of the Automatic Exchange Right,
the Exchange Right and of their right to instruct the Trustee with respect to the exercise of the Exchange Right in respect of the Exchangeable Shares held by a Beneficiary. 

5.3   Exercise of Exchange Right  

        The Exchange Right shall be and remain vested in and exercisable by the Trustee. Subject to Section 6.15 hereof, the Trustee shall exercise the Exchange
Right only on the basis of instructions received pursuant to this ARTICLE 5 from Beneficiaries entitled to instruct the Trustee as to the exercise thereof. To the extent that no instructions are
received from a Beneficiary with respect to the Exchange Right, the Trustee shall not exercise or permit the exercise of the Exchange Right. 

5.4   Purchase Price  

        The purchase price payable by US Gold or Callco, as the case may be, for each Exchangeable Share to be purchased by US Gold or Callco, as the case may be, under
the Exchange Right shall be an amount per share equal to the Exchangeable Share Price on the last Business Day prior to the day of closing of
the purchase and sale of such Exchangeable Share under the Exchange Right. The Exchangeable Share Price for each such Exchangeable Share so purchased may be satisfied only by US Gold or Callco
delivering or causing to be delivered to the Trustee, on behalf of the relevant Beneficiary, the Exchangeable Share Consideration representing such Exchangeable Share Price. 

5.5   Exercise Instructions  

        Subject to the terms and conditions herein set forth, a Beneficiary shall be entitled, upon the occurrence and during the continuance of an Insolvency Event, to
instruct the Trustee to exercise the Exchange Right with respect to all or any part of the Exchangeable Shares registered in the name of such Beneficiary on the books of Exchangeco. To cause the
exercise of the Exchange Right by the Trustee, the Beneficiary shall deliver to the Trustee, in person or by certified or registered mail, at its principal office(s) in Toronto, Ontario or Calgary,
Alberta or at such other places in Canada as the Trustee may from time to time designate by written notice to the Beneficiaries, the certificates representing the Exchangeable Shares which such
Beneficiary desires US Gold or Callco to purchase, duly endorsed in blank for transfer, and accompanied by such other documents and instruments as may be required to effect a transfer of Exchangeable
Shares under the ABCA, the by-laws of Exchangeco and such additional documents and instruments as the Trustee or Exchangeco may reasonably require together with: (a) a duly
completed form of notice of exercise of the Exchange Right, contained on the 

10

 

reverse
of or attached to the Exchangeable Share certificates, stating (i) that the Beneficiary thereby instructs the Trustee to exercise the Exchange Right so as to require US Gold or Callco
to purchase from the Beneficiary the number of Exchangeable Shares specified therein, (ii) that such Beneficiary has good title to and owns all such Exchangeable Shares to be acquired by US
Gold or Callco free and clear of all liens, claims, security interests and encumbrances, (iii) the names in which the certificates representing shares of US Gold Common Stock issuable in
connection with the exercise of the Exchange Right are to be issued and (iv) the names and addresses of the persons to whom such new certificates should be delivered; and (b) payment (or
evidence satisfactory to the Trustee, Exchangeco and US Gold of payment) of the Taxes (if any) payable as contemplated by Section 5.8 of this Agreement. If only a portion of the Exchangeable
Shares represented by any certificate or certificates delivered to the Trustee are to be purchased by US Gold or Callco under the Exchange Right, a new certificate for the balance of such Exchangeable
Shares shall be issued to the holder at the expense of Exchangeco. 

5.6   Delivery of Shares of US Gold Common Stock; Effect of Exercise  

        Promptly after receipt by the Trustee of the certificates representing the Exchangeable Shares that a Beneficiary desires US Gold or Callco to purchase under the
Exchange Right, together with such documents and instruments of transfer and a duly completed form of notice of exercise of the Exchange Right (and payment of Taxes, if any, payable as contemplated by
Section 5.8 or evidence thereof), duly endorsed for transfer to US Gold or Callco, the Trustee shall notify US Gold, Callco and Exchangeco of its receipt of the same, which notice to US Gold,
Callco and Exchangeco shall constitute exercise of the Exchange Right by the Trustee on behalf of the Beneficiary in respect of such Exchangeable Shares, and US Gold or Callco shall promptly
thereafter deliver or cause to be delivered to the Trustee, for delivery to the Beneficiary of such Exchangeable Shares (or to such other persons, if any, properly designated by such Beneficiary), the
Exchangeable Share Consideration deliverable in connection with such exercise of the Exchange Right; provided, however, that no such delivery shall be made unless and until the Beneficiary requesting
the same shall have paid (or provided evidence satisfactory to the Trustee, Exchangeco, Callco and US Gold of the payment of) the Taxes (if any) payable as contemplated by Section 5.8 of this
Agreement. Immediately upon the giving of notice by the Trustee to US Gold, Callco and Exchangeco of the exercise of the Exchange Right, as provided in this Section 5.6, the closing of the
transaction of purchase and sale contemplated by the Exchange Right shall be deemed to have occurred, and the Beneficiary of such Exchangeable Shares shall be deemed to have transferred to US Gold
(or, at US Gold's option, to Callco) all of its right, title and interest in and to such Exchangeable Shares and the related interest in the Trust Estate and shall not be entitled to exercise any of
the rights of a holder in respect thereof, other than the right to receive its proportionate part of the total Exchangeable Share Consideration therefor, unless such Exchangeable Share Consideration
is not delivered by US Gold or Callco to the Trustee, for delivery to such Beneficiary (or to such other persons, if any, properly designated by such Beneficiary), within five Business Days of the
date of the giving of such notice by the Trustee, in which case the rights of the Beneficiary shall remain unaffected until such Exchangeable Share Consideration is so delivered and any such cheque or
other property comprising a portion of the Exchangeable Share Consideration is paid. Upon delivery of such Exchangeable Share Consideration to the Trustee, the Trustee shall promptly deliver such
Exchangeable Share Consideration to such Beneficiary (or such other person, if any, properly designated by such Beneficiary). Concurrently with the closing of the transaction of purchase and sale
contemplated by the Exchange Right, such Beneficiary shall be considered and deemed for all purposes to be the holder of the shares of US Gold Common Stock delivered to it pursuant to the Exchange
Right. 

11

 

5.7   Exercise of Exchange Right Subsequent to Retraction  

        In the event that a Beneficiary has exercised its retraction right under Article 6 of the Share Provisions to require Exchangeco to redeem any or all of
the Exchangeable Shares held by the Beneficiary (the "Retracted Shares") and is notified by Exchangeco pursuant to Section 6.1(d) of the Share
Provisions that Exchangeco will not be permitted as a result of solvency requirements of applicable Law to redeem all such Retracted Shares, subject to receipt by the Trustee of written notice to that
effect from Exchangeco and provided that neither US Gold nor Callco shall have exercised its Retraction Call
Right with respect to the Retracted Shares and that the Beneficiary shall not have revoked the retraction request delivered by the Beneficiary to Exchangeco pursuant to Section 6.1(e) of the
Share Provisions, the retraction request will constitute and will be deemed to constitute notice from the Beneficiary to the Trustee instructing the Trustee to exercise the Exchange Right with respect
to those Retracted Shares that Exchangeco is unable to redeem. In any such event, Exchangeco hereby agrees with the Trustee and in favour of the Beneficiary promptly to notify the Trustee of such
prohibition against Exchangeco and to forward or cause to be forwarded to the Trustee all relevant materials delivered by the Beneficiary to Exchangeco or to the Transfer Agent (including a copy of
the retraction request delivered pursuant to Section 6.1(a) of the Share Provisions) in connection with such proposed redemption of the Retracted Shares and the Trustee will thereupon exercise
the Exchange Right with respect to the Retracted Shares that Exchangeco is not permitted to redeem and will require US Gold or, at US Gold's option, Callco, to purchase such shares in accordance with
the provisions of this ARTICLE 5. 

5.8   Stamp or Other Transfer Taxes  

        Upon any sale of Exchangeable Shares to US Gold or Callco pursuant to the Exchange Right or the Automatic Exchange Right, the share certificate or certificates
representing shares of US Gold Common Stock to be delivered in connection with the payment of the total purchase price therefor shall be issued in the name of the Beneficiary of the Exchangeable
Shares so sold or in such names as such Beneficiary may otherwise direct in writing without charge to the holder of the Exchangeable Shares so sold, provided, however, that such Beneficiary:
(a) shall pay (and none of US Gold, Callco, Exchangeco or the Trustee shall be required to pay) any documentary, stamp, transfer or other similar Taxes that may be payable in respect of any
transfer involved in the issuance or delivery of such shares to a person other than such Beneficiary; or (b) shall have established to the satisfaction of the Trustee, US Gold, Callco and
Exchangeco that such Taxes, if any, have been paid. 

5.9   Notice of Insolvency Event  

        As soon as practicable following the occurrence of an Insolvency Event or any event that with the giving of notice or the passage of time or both would be an
Insolvency Event, Exchangeco and US Gold shall give written notice thereof to the Trustee. As soon as practicable after receiving notice from Exchangeco or US Gold or from any other person of the
occurrence of an Insolvency Event, the Trustee will mail to each Beneficiary, at the expense of US Gold, a notice of such Insolvency Event in the form provided by US Gold, which notice shall contain a
brief statement of the right of the Beneficiaries with respect to the Exchange Right. 

5.10 Call Rights  

        The Liquidation Call Right, the Redemption Call Right, the Retraction Call Right, the Change of Law Call Right, the Automatic Exchange Right and the Exchange
Right are hereby agreed, acknowledged, consented to and confirmed, and it is agreed and acknowledged that such rights are granted as part of the consideration for the obligations of US Gold under this
Agreement. 

12

 

5.11 Automatic Exchange Right  

	(1)
	US
Gold shall give the Trustee written notice of each of the following events (each a "US Gold Liquidation
Event") at the time set forth below:

	(a)
	in
the event of any determination by the board of directors of US Gold to institute voluntary liquidation, dissolution or winding up proceedings with
respect to US Gold or to effect any other distribution of assets of US Gold among its stockholders for the purpose of winding up its affairs, at least 30 days prior to the proposed effective
date of such liquidation, dissolution, winding up or other distribution; and

	(b)
	promptly
following the earlier of (i) receipt by US Gold of notice of and (ii) US Gold otherwise becoming aware of any instituted claim, suit,
petition or other proceeding with respect to the involuntary liquidation, dissolution or winding up of US Gold or to effect any other distribution of assets of US Gold among its stockholders for the
purpose of winding up its affairs in each case where US Gold has failed to contest in good faith any such proceeding commenced in respect of US Gold within 30 days of becoming aware thereof.

	(2)
	Promptly
following receipt by the Trustee from US Gold of notice of any US Gold Liquidation Event contemplated by Section 5.11(1)(a) or 5.11(1)(b),
the Trustee will give notice or cause such notice to be given thereof to the Beneficiaries. Such notice shall be provided by US Gold to the Trustee and shall include a brief description of the
automatic exchange of Exchangeable Shares for shares of US Gold Common Stock provided for in Section 5.11(3) below (the "Automatic Exchange
Right").

	(3)
	In
order that the Beneficiaries will be able to participate on a pro rata basis with the holders of shares of US Gold Common Stock in the distribution of
assets of US Gold in connection with a US Gold Liquidation Event, immediately prior to the effective date (the "US Gold Liquidation Event Effective
Date") of a US Gold Liquidation Event all of the then outstanding Exchangeable Shares (other than Exchangeable Shares held by US Gold or its Subsidiaries) shall be
automatically exchanged for shares of US Gold Common Stock. To effect such automatic exchange, US Gold shall purchase each Exchangeable Share outstanding on the last Business Day immediately prior to
the US Gold Liquidation Event Effective Date and held by a Beneficiary, and each such Beneficiary shall sell free and clear of any liens, claims or encumbrances the Exchangeable Shares held by it at
such time, for a purchase price per share equal to the Exchangeable Share Price on the last Business Day immediately prior to the US Gold Liquidation Event Effective Date, which shall be satisfied in
full by US Gold delivering to such holder the Exchangeable Share Consideration representing such Exchangeable Share Price.

	(4)
	On
the Business Day immediately prior to the US Gold Liquidation Event Effective Date, the closing of the transaction of purchase and sale contemplated by
the automatic exchange of Exchangeable Shares for shares of US Gold Common Stock shall be deemed to have occurred, and each Beneficiary shall be deemed to have transferred to US Gold all of such
Beneficiary's right, title and interest in and to such Exchangeable Shares free and clear of any liens, claims or encumbrances and shall cease to be a holder of such Exchangeable Shares and US Gold
shall deliver or cause to be delivered to the Trustee, for delivery to such holders, the Exchangeable Share Consideration deliverable upon the automatic exchange of the Exchangeable Shares.
Concurrently with each such Beneficiary ceasing to be a holder of Exchangeable Shares, such Beneficiary shall be considered and deemed for all purposes to be the holder of the shares of US Gold Common
Stock delivered to it, or to the Trustee on its behalf, pursuant to the automatic exchange of such Beneficiary's Exchangeable Shares for shares of US Gold Common Stock and the certificates held by
such Beneficiary previously 

13

 

representing
the Exchangeable Shares exchanged by such Beneficiary with US Gold pursuant to such automatic exchange shall thereafter be deemed to represent the shares of US Gold Common Stock delivered
to such Beneficiary by US Gold pursuant to such automatic exchange. Upon the request of any Beneficiary and the surrender by such Beneficiary of Exchangeable Share certificates deemed to represent
shares of US Gold Common Stock, duly endorsed in blank and accompanied by such instruments of transfer as US Gold may reasonably require, the Trustee shall deliver or cause to be delivered to such
Beneficiary certificates representing the shares of US Gold Common Stock of which such Beneficiary is the holder and the remainder of the Exchangeable Share Consideration, if any. 

5.12 US Gold Common Stock  

        The obligations of US Gold to issue shares of US Gold Common Stock pursuant to the Automatic Exchange Right or the Exchange Right are subject to all applicable
Laws and regulatory or stock exchange requirements. 

5.13 Withholding Rights  

        US Gold, Callco, Exchangeco and the Trustee shall be entitled to deduct and withhold from any consideration otherwise payable to any holder of Exchangeable Shares
or US Gold Common Stock such amounts as US Gold, Callco, Exchangeco or the Trustee is required to deduct and withhold with respect to such payment under the Tax Act or the U.S. Tax Code or any
provision of federal, provincial, state, territorial, local or foreign Tax Law, in each case as amended or succeeded. The Trustee may act and rely on the advice of counsel with respect to such
matters. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes as having been paid to the holder of the shares in respect of which such deduction and
withholding was made, provided that such withheld amounts are actually remitted to the appropriate Taxing Authority. To the extent that the amount so required to be deducted or withheld from any
payment to a holder exceeds the cash portion of the consideration otherwise payable to the holder, US Gold, Callco, Exchangeco and the Trustee are hereby authorized to sell or otherwise dispose of
such portion of the consideration as is necessary to provide sufficient funds to US Gold, Callco, Exchangeco or the Trustee, as the case may be, to enable it to comply with such deduction or
withholding requirement and US Gold, Callco, Exchangeco or the Trustee shall notify the holder thereof and remit to such holder any unapplied balance of the net proceeds of such sale. 

5.14 No Fractional Entitlements  

        Notwithstanding anything contained in this Agreement, including, without limitation, ARTICLE 5, no Beneficiary (or the Trustee as trustee for and on behalf of,
and for the use and benefit of a Beneficiary) shall be entitled to, and US Gold and Callco will not deliver, fractions of shares of US Gold Common Stock. Where the application of the provisions of
this Agreement, including, without limitation, ARTICLE 5, would otherwise result in a Beneficiary (or the Trustee, on behalf of the Beneficiary) receiving a fraction of a share of US Gold Common Stock
the Beneficiary (or the Trustee on behalf of the Beneficiary) shall be entitled to receive the nearest whole number of shares of US Gold Common Stock.

	(2)
	In
the exercise of such rights, powers, duties and authorities the Trustee shall have (and is granted) such incidental and additional rights, powers, duties
and authority not in conflict with any of the provisions of this Agreement as the Trustee, acting in good faith and in the reasonable exercise of its discretion, may deem necessary, appropriate or
desirable to effect the purpose of the Trust. Any exercise of duties or of discretionary rights, powers and authorities by the Trustee shall be final, conclusive and binding upon all persons.

advisable. US Gold shall retain qualified experts or advisors for the purpose of providing such tax advice or assistance. 

6.6   Indemnification Prior To Certain Actions By Trustee  

	(1)

Trustee shall exercise any or all of the rights, duties, powers or authorities vested in it by this Agreement at the request, order or direction of any

        No Beneficiary shall have the right to institute any action, suit or proceeding or to exercise any other remedy authorized by this Agreement for the purpose of

        Except as otherwise specifically provided in this Agreement, the Trustee shall not be bound to act in accordance with any direction or request of US Gold, Callco
and/or Exchangeco or of the respective directors thereof until a duly authenticated copy of the instrument or resolution containing such direction or request shall have been delivered to the Trustee,
and the Trustee shall be empowered to act upon any such copy purporting to be authenticated and believed by the Trustee to be genuine. The Trustee shall have the right not to act and shall not be
liable for refusing to act if, due to a lack of information or for any other reason whatsoever, the Trustee, in its sole judgment, determines that such act might cause it to be in
non-compliance with any applicable anti-money laundering or anti-terrorist legislation or regulation. Further, should the Trustee, in its sole judgment, determine
at any time that its acting under this Agreement has resulted in its being in non-compliance with any applicable anti-money laundering or anti-terrorist legislation
or regulation, then it shall have the right to resign on 10 days written notice to the other parties to this Agreement, provided that: (a) the Trustee's written notice shall describe the
circumstances of such non-compliance; and (b) if such circumstances are rectified to the Trustee's satisfaction within such 10 day period, then such resignation shall not be
effective.

6.14 Authority to Carry on Business  

        The Trustee represents to US Gold, Callco and Exchangeco that at the date of execution and delivery by it of this Agreement it is authorized to carry on the
business of a trust company in each of the provinces and territories of Canada but if, notwithstanding the provisions of this Section 6.14, it ceases to be so authorized to carry on business,
the validity and enforceability of this Agreement and the Voting Rights, the Exchange Right, the Automatic Exchange Right and the other rights granted in or resulting from the Trustee being a party to
this Agreement shall not be affected in any manner whatsoever by reason only of such event but the Trustee shall, within 90 days after ceasing to be authorized to carry on the business of a
trust company in any province or territory of Canada, either become so authorized or resign in the manner and with the effect specified in ARTICLE 9. 

6.15 Conflicting Claims  

	(1)
	If
conflicting claims or demands are made or asserted with respect to any interest of any Beneficiary in any Exchangeable Shares, including any disagreement
between the heirs, representatives, successors or assigns succeeding to all or any part of the interest of any Beneficiary in any Exchangeable Shares, resulting in conflicting claims or demands being
made in connection with such interest, then the Trustee shall be entitled, in its sole discretion, to refuse to recognize or to comply with any such claims or demands. In so refusing, the Trustee may
elect not to exercise any Voting Rights, Exchange Right, Automatic Exchange Right or other rights subject to such conflicting claims or demands and, in so doing, the Trustee shall not be or become
liable to any person on account of such election or its failure or refusal to comply with any such conflicting claims or demands. The Trustee shall be entitled to continue to refrain from acting and
to refuse to act until:

	(a)
	the
rights of all adverse claimants with respect to the Voting Rights, Exchange Right, Automatic Exchange Right or other rights subject to such conflicting
claims or demands have been adjudicated by a final judgement of a court of competent jurisdiction and all rights of appeal have expired; or

	(b)
	all
differences with respect to the Voting Rights, Exchange Right, Automatic Exchange Right or other rights subject to such conflicting claims or demands
have been conclusively settled by a valid written agreement binding on all such adverse claimants, and the Trustee shall have been furnished with an executed copy of such agreement.

	(2)
	If
the Trustee elects to recognize any claim or comply with any demand made by any such adverse claimant, it may in its discretion require such claimant to
furnish such surety bond or other security satisfactory to the Trustee as it shall deem appropriate to fully indemnify it as between all conflicting claims or demands. 

6.16 Acceptance of Trust  

        The Trustee hereby accepts the Trust created and provided for, by and in this Agreement and agrees to perform the same upon the terms and conditions herein set
forth and to hold all rights, privileges and benefits conferred hereby and by Law in trust for the various persons who shall from time to time be Beneficiaries, subject to all the terms and conditions
herein set forth. 

6.17 Maintenance of Office or Agency  

        US Gold will maintain in Toronto, Ontario and Calgary, Alberta an office or agency where certificates representing Exchangeable Shares may be presented or
surrendered for exchange by Beneficiaries and where notices and demands to or upon US Gold or Exchangeco in respect of the Exchangeable Shares may be served. US Gold will give prompt written notice to
the Trustee of the 

20

 

location,
and any change in the location, of such office or agency. If at any time US Gold shall fail to maintain any such office or agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be served at the Corporate Trust Office of the Trustee, and US Gold and Exchangeco hereby appoint the Trustee as their agent to receive
all such presentations, surrenders, notices and demands. Furthermore, copies of all US Gold proxy materials will be made available for inspection by any Beneficiary at such office or agency. 

6.18 Third Party Interests  

        Each party to this Agreement hereby represents to the Trustee that any account to be opened by, or interest to held by the Trustee in connection with this
Agreement, for or to the credit of such party, either (i) is not intended to be used by or on behalf of any third party; or (ii) is intended to be used by or on behalf of a third party,
in which case such party hereto agrees to complete and execute forthwith a declaration in the Trustee's prescribed form as to the particulars of such third party. 

6.19 Privacy  

        The parties acknowledge that Canadian federal and/or provincial legislation that addresses the protection of individuals' personal information (collectively,
"Privacy Laws") applies to obligations and activities under this Agreement. Despite any other provision of this Agreement, no party shall take or direct
any action that would contravene, or cause the others to contravene, applicable Privacy Laws. The parties shall, prior to transferring or causing to be transferred personal information to the Trustee,
obtain and retain required consents of the relevant individuals to the collection, use and disclosure of their personal information, or shall have determined that such consents either have previously
been given upon which the parties can rely or are not required under the Privacy Laws. The Trustee shall use commercially reasonable efforts to ensure that its services hereunder comply with Privacy
Laws. Specifically, the Trustee agrees: (a) to have a designated chief privacy officer; (b) to maintain policies and procedures to protect personal information and to receive and respond
to any privacy complaint or inquiry; (c) to use personal information solely for the purposes of providing its services under or ancillary to this Agreement and not to use it for any other
purpose except with the consent of or
direction from the other parties or the individual involved; (d) not to sell or otherwise improperly disclose personal information to any third party; and (e) to employ administrative,
physical and technological safeguards to reasonably secure and protect personal information against loss, theft, or unauthorized access, use or modification.

        The Trustee will invoice US Gold for its fees and expenses under this Agreement. US Gold, Callco and Exchangeco jointly and severally agree to pay the Trustee
reasonable compensation for all of the services rendered by it under this Agreement and will reimburse the Trustee for all reasonable expenses (including Taxes other than Taxes based on the net income
or capital of the Trustee, fees paid and disbursements reimbursed to legal counsel and other experts and advisors and agents and assistants, and travel expenses) and disbursements, including the cost
and expense of any suit or litigation of any character and any proceedings before any governmental agency, and including fees and expenses for attendance at any US Gold Meeting, reasonably incurred by
the Trustee in connection with its duties under this Agreement; provided that US Gold, Callco and Exchangeco shall have no obligation to reimburse the Trustee for any expenses or disbursements paid,

wilful misconduct. 

21

 
 
 

  ARTICLE 8
  INDEMNIFICATION AND LIMITATION OF LIABILITY    
    

8.1   Indemnification of the Trustee  

	(1)
	US
Gold, Callco and Exchangeco jointly and severally agree to indemnify and hold harmless the Trustee and each of its directors, officers, employees and
agents appointed and acting in accordance with this Agreement (collectively, the "Indemnified Parties") against all claims, losses, damages, reasonable
costs, penalties, fines and reasonable expenses (including reasonable expenses of the Trustee's legal counsel) which, without fraud, gross negligence, recklessness, wilful misconduct or bad faith on
the part of such Indemnified Party, may be paid, incurred or suffered by the Indemnified Party by reason or as a result of the Trustee's acceptance or administration of the Trust, its compliance with
its duties set forth in this Agreement, or any written or oral instruction delivered to the Trustee by US Gold, Callco or Exchangeco pursuant hereto.

	(2)
	US
Gold, Callco or Exchangeco shall be notified by the Trustee of the written assertion of a claim or of any action commenced against the Indemnified
Parties, promptly after any of the Indemnified Parties shall have received any such written assertion of a claim or shall have been served with a summons or other first legal process giving
information as to the nature and basis of the claim; provided that the omission to so notify US Gold, Callco or Exchangeco shall not relieve US Gold, Callco or Exchangeco of any liability which any of
them may have to any Indemnified Party except to the extent that any such delay prejudices the defence of any such claim or action or results in any increase in the liability which US Gold, Callco or
Exchangeco have under this indemnity. Subject to (ii) below, US Gold, Callco and Exchangeco shall be entitled to participate at their own expense in the defence and, if US Gold, Callco and
Exchangeco so elect at any time after receipt of such notice, either of them may assume the defence of any suit brought to enforce any such claim. The Trustee shall have the right to employ separate
counsel in any such suit and participate in the defence thereof, but the fees and expenses of such counsel shall be at the expense of the Trustee unless: (i) the employment of such counsel has
been authorized by US Gold, Callco or Exchangeco; or (ii) the named parties to any such suit include both the Trustee and US Gold, Callco or Exchangeco and the Trustee shall have been advised
by counsel acceptable to US Gold, Callco or Exchangeco that there may be one or more legal defences available to the Trustee that are different from or in addition to those available to US Gold,
Callco or Exchangeco and that, in the judgement of such counsel, would present a conflict of interest were a joint representation to be undertaken (in which case US Gold, Callco and Exchangeco shall
not have the right to assume the defence of such suit on behalf of the Trustee but shall be liable to pay the reasonable fees and expenses of counsel for the Trustee). The indemnities contained in
this ARTICLE 8 shall survive the termination of the Trust and the resignation or removal of the Trustee. 

8.2   Limitation of Liability  

        The Trustee shall not be held liable for any loss which may occur by reason of depreciation of the value of any part of the Trust Estate or any loss incurred on
any investment of funds pursuant to this Agreement, except to the extent that such loss is attributable to the fraud, gross negligence, recklessness, wilful misconduct or bad faith on the part of the
Trustee. 

8.3   Force Majeure  

        Except for the payment obligations of US Gold, Callco and Exchangeco contained herein, no party shall be liable to the other, or held in breach of this Agreement,
if prevented, hindered or delayed in the performance or observance of any provision contained herein by reason of act of God, riots, 

22

 

terrorism,
acts of war, epidemics, governmental action or judicial order, earthquakes or any other similar causes (including, but not limited to, mechanical, electronic or communication interruptions,
disruptions or failures). Performance times under this Agreement shall be extended for a period of time equivalent to the time lost because of any delay that is excusable under this
Section 8.3. 

 
 

  ARTICLE 9
  CHANGE OF TRUSTEE    
    

9.1   Resignation  

        The Trustee, or any trustee hereafter appointed, may at any time resign by giving written notice of such resignation to US Gold, Callco and Exchangeco specifying
the date on which it desires to resign, provided that such notice shall not be given less than sixty (60) days before such desired resignation date unless US Gold, Callco and Exchangeco
otherwise agree and provided further that such resignation shall not take effect until the date of the appointment of a successor trustee and the acceptance of such appointment by the successor
trustee. Upon receiving such notice of resignation, Exchangeco shall promptly appoint a successor trustee, which shall be a corporation organized and
existing under the Laws of Canada and authorized to carry on the business of a trust company in all provinces and territories of Canada, by written instrument in duplicate, one copy of which shall be
delivered to the resigning trustee and one copy to the successor trustee. Failing the appointment and acceptance of a successor trustee, a successor trustee may be appointed by order of a court of
competent jurisdiction upon application of one or more of the parties to this Agreement. If the retiring trustee is the party initiating an application for the appointment of a successor trustee by
order of a court of competent jurisdiction, US Gold, Callco and Exchangeco shall be jointly and severally liable to reimburse the retiring trustee for its legal costs and expenses in connection with
same. 

9.2   Removal  

        The Trustee, or any trustee hereafter appointed, may (provided a successor trustee is appointed) be removed at any time on not less than thirty (30) days'
prior notice by written instrument executed by US Gold, Callco and Exchangeco, in duplicate, one copy of which shall be delivered to the trustee so removed and one copy to the successor trustee,
provided that such removal shall not take effect until the date of acceptance of appointment by the successor trustee. 

9.3   Successor Trustee  

        Any successor trustee appointed as provided under this Agreement shall execute, acknowledge and deliver to US Gold, Callco and Exchangeco and to its predecessor
trustee an instrument accepting such appointment. Thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor under this Agreement, with the like effect as if originally named as trustee in this Agreement.
However, on the written request of US Gold, Callco and Exchangeco or of the successor trustee, the trustee ceasing to act shall, upon payment of any amounts then due to it pursuant to the provisions
of this Agreement, execute and deliver an instrument transferring to such successor trustee all the rights and powers of the trustee so ceasing to act. Upon the request of any such successor trustee,
US Gold, Callco, Exchangeco and such predecessor trustee shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such
rights and powers. Notwithstanding the foregoing, any corporation to which all or substantially all of the business of the Trustee is transferred shall automatically become the successor trustee
without any further act. 

23

 

9.4   Notice of Successor Trustee  

        Upon acceptance of appointment by a successor trustee as provided herein, US Gold, Callco and Exchangeco shall cause to be mailed notice of the succession of such
trustee hereunder to each Beneficiary specified in a List. If US Gold, Callco or Exchangeco shall fail to cause such notice to be mailed within 10 days after acceptance of appointment by the
successor trustee, the successor trustee shall cause such notice to be mailed at the expense of US Gold, Callco and Exchangeco 

 
 

  ARTICLE 10
  US GOLD SUCCESSORS    
    

10.1 Certain Requirements in Respect of Combination, etc.  

        US Gold shall not enter into any transaction (whether by way of reconstruction, reorganization, consolidation, arrangement, merger, transfer, sale, lease or
otherwise) whereby all or substantially all of its undertaking, property and assets would become the property of any other person or, in the case of a merger, of the continuing corporation resulting
therefrom unless, but may do so if: (i) such other person or continuing corporation (the "US Gold Successor") by operation of Law, becomes,
without more, bound by the terms and provisions of this Agreement or, if not so bound, executes, prior to or contemporaneously with the consummation of such transaction, an agreement supplemental
hereto and such other instruments (if any) as are necessary or advisable to evidence the assumption by the US Gold Successor of liability for all moneys payable and property deliverable hereunder and
the covenant of such US Gold Successor to pay and deliver or cause to be delivered the same and its agreement to observe and perform all the covenants and obligations of US Gold under this Agreement;
and (ii) such transaction shall be upon such terms and conditions as substantially to preserve and not to impair in any material respect any of the rights, duties, powers and authorities of the
Trustee or of the Beneficiaries hereunder. 

10.2 Vesting of Powers in Successor  

        Whenever the conditions of Section 10.1 have been duly observed and performed, the parties, if required by Section 10.1, shall execute and deliver
the supplemental trust agreement provided for in Section 10.1 and thereupon the US Gold Successor and such other person that may then be the issuer of the shares of US Gold Common Stock shall
possess and from time to time may exercise each and
every right and power of US Gold under this Agreement in the name of US Gold or otherwise and any act or proceeding by any provision of this Agreement required to be done or performed by the board of
directors of US Gold or any officers of US Gold may be done and performed with like force and effect by the directors or officers of such US Gold Successor. 

10.3 Wholly-Owned Subsidiaries  

        Nothing herein shall be construed as preventing the amalgamation or merger of any direct or indirect wholly-owned Subsidiary of US Gold with or into US Gold or
the winding-up, liquidation or dissolution of any direct or indirect wholly-owned Subsidiary of US Gold, provided that all of the assets of such Subsidiary are transferred to US Gold or
another direct or indirect wholly-owned Subsidiary of US Gold, and any such transactions are expressly permitted by this ARTICLE 10. 

10.4 Successor Transaction  

        In the event of an US Gold Control Transaction: 

	(a)
	in
which US Gold merges or amalgamates with, or in which all or substantially all of the then outstanding shares of US Gold Common Stock are acquired by,
one or more other corporations to which US Gold is, immediately before such merger, amalgamation or acquisition, "related" within the meaning of the Tax Act (otherwise than by virtue of a right
referred to in paragraph 251(5)(b) thereof); 

24

 

	(b)
	which
does not result in an acceleration of the Redemption Date in accordance with paragraph (b) of that definition; and

	(c)
	in
which all or substantially all of the then outstanding shares of US Gold Common Stock are converted into or exchanged for shares or rights to receive
such shares (the "Other Shares") of another corporation (the "Other Corporation") that, immediately
after such US Gold Control Transaction, owns or controls, directly or indirectly, US Gold, then:

	(i)
	all
references herein to "US Gold" shall thereafter be and be deemed to be references to "Other Corporation" and all references herein to shares of "US Gold
Common Stock" shall thereafter be and be deemed to be references to "Other Shares" (with appropriate adjustments, if any, as are required to result in a holder of Exchangeable Shares on the exchange,
redemption or retraction of such shares pursuant to the Share Provisions or Article 8 of the Plan of Arrangement or exchange of such shares pursuant to this Agreement immediately subsequent to
the US Gold Control Transaction being entitled to receive that number of Other Shares equal to the number of Other Shares such holder of Exchangeable Shares would have received if the exchange,
redemption or retraction of such shares pursuant to the Share Provisions or Article 8 of the Plan of Arrangement, or exchange of such shares pursuant to this Agreement had occurred immediately
prior to the US Gold Control Transaction and the US Gold Control Transaction was completed, but subject to subsequent adjustments to reflect any subsequent changes in the share capital of the issuer
of the Other Shares, including without limitation, any sub-division, consolidation or reduction of share capital) without any need to amend the terms and conditions of this Agreement and
without any further action required; and

	(ii)
	US
Gold shall cause the Other Corporation to deposit one or more voting securities of such Other Corporation to allow Beneficiaries to exercise voting
rights in respect of the Other Corporation substantially similar to those provided for in this Agreement.

in reliance upon a certificate of Exchangeco, having in mind the best interests of the Beneficiaries, it may be expedient to make, provided that such boards of directors and the Trustee,
acting in reliance upon a certificate of Exchangeco, shall be of the opinion that such amendments and modifications will not be prejudicial to the rights or interests of the Beneficiaries as a whole;
or

	(c)
	for
any other purposes not inconsistent with the provisions of this Agreement, including to make or evidence any amendment or modification to this Agreement

date, record date and payment date for the corresponding dividend on the US Gold Common Stock; and

	(ii)
	the
record date and effective date for an Equivalent Stock Subdivision shall be the same as the record date and payment date for the stock dividend or

	take
all such actions and do all such things as are reasonably necessary or desirable to enable and permit Exchangeco, in accordance with applicable Law, to

	take
all such actions and do all such things as are reasonably necessary or desirable to enable and permit Exchangeco, in accordance with applicable Law, to

all such things as are necessary or desirable to enable and permit Exchangeco to cause to be delivered shares of US Gold Common Stock to the holders of Exchangeable Shares, in accordance with the
provisions of Article 6 or Article 7 of the Share Provisions, as the case may be;

	(f)
	take
all such actions and do all such things as are reasonably necessary or desirable to enable and permit Callco or US Gold, in accordance with applicable
Law, to perform its obligations arising upon the exercise by it of the Liquidation Call Right, the Retraction Call Right, the Change of Law Call Right or the Redemption Call Right, including all such

action that is designed to result in the liquidation, dissolution or winding up of Exchangeco or any other distribution of the assets of Exchangeco among its shareholders for the purpose of winding up
its affairs.

and property as is necessary to enable Exchangeco to pay or otherwise satisfy its obligations with respect to the applicable dividend, Liquidation Amount, Retraction Price or Redemption Price, once
such amounts become payable under the terms of this Agreement or the Share Provisions, in each case for the benefit of Non-Affiliated Holders from time to time of the Exchangeable Shares,
and Exchangeco will use such funds, assets and property so segregated exclusively for the payment of dividends and the payment or other satisfaction of the Liquidation Amount, the Retraction Price or
the Redemption
Price, as applicable net of any corresponding withholding Tax obligations and for the remittance of such withholding Tax obligations.

        US Gold hereby represents, warrants and covenants in favour of Exchangeco and Callco that US Gold has reserved for issuance and will, at all times while any
Exchangeable Shares are outstanding, keep available, free from pre-emptive and other rights, out of its authorized and unissued capital stock such number of shares of US Gold Common Stock
(or other shares or securities into which US Gold Common Stock may be reclassified or changed as contemplated by Section 2.7): (a) as is equal to the sum of (i) the number of
Exchangeable Shares issued and outstanding from time to time, and (ii) the number of Exchangeable Shares issuable upon the exercise of all rights to acquire Exchangeable Shares outstanding from
time to time; and (b) as are now and may hereafter be required to enable and permit each of US Gold, Callco and Exchangeco to meet its obligations under the Voting and Exchange Trust Agreement,

shares of US Gold Common Stock to the Non-Affiliated Holders.

proceedings with respect to Exchangeco or to effect any other distribution of the assets of Exchangeco among its shareholders for the purpose of winding up its affairs, at least 30 days prior
to the proposed effective date of such liquidation, dissolution, winding-up or other distribution; 

4

 

	(b)
	promptly
upon the earlier of (i) receipt by Exchangeco of notice of, and (ii) Exchangeco otherwise becoming aware of any threatened or
instituted claim, suit, petition or other proceedings with respect to the involuntary liquidation, dissolution or winding-up of Exchangeco or to effect any other distribution of the assets
of Exchangeco among its shareholders for the purpose of winding up its affairs;

	(c)
	immediately
upon receipt by Exchangeco of a Retraction Request;

	(d)
	on
the same date on which notice of redemption is given to holders of Exchangeable Shares, upon the determination of a Redemption Date in accordance with

upon the issuance by Exchangeco of any Exchangeable Shares or rights to acquire Exchangeable Shares (other than the issuance of Exchangeable Shares
or rights to acquire Exchangeable Shares pursuant to the Arrangement); and

	(f)
	promptly,
upon receiving notice of a Change of Law (as such term is defined in the Plan of Arrangement). 

2.5   Delivery of US Gold Common Stock  

        Upon notice from Exchangeco or Callco of any event that requires Exchangeco or Callco to cause to be delivered shares of US Gold Common Stock to any holder of
Exchangeable Shares, US Gold shall, forthwith issue and deliver or cause to be delivered the requisite number of shares of US Gold Common Stock to Exchangeco or Callco, as appropriate, and Exchangeco
or Callco, as the case may be, shall forthwith deliver or cause to be delivered the requisite number of shares of US Gold Common Stock to or for the benefit of the former holder of the surrendered
Exchangeable Shares. All such shares of US Gold Common Stock shall be duly authorized and validly issued as fully paid, non-assessable, free of pre-emptive rights and shall be
free and clear of any lien, claim or encumbrance. In consideration for the issuance and delivery of each such share of US Gold Common Stock, Exchangeco or Callco, as the case may be, shall subscribe a
cash amount or pay a purchase price equal to the fair market value of the shares of US Gold Common Stock, and US Gold shall contribute or cause to be contributed to the capital of Exchangeco or
Callco, as the case
may be, the cash necessary for Exchangeco or Callco, as the case may be, to effect such subscription or payment. 

2.6   Qualification of US Gold Common Stock  

        US Gold covenants that it will use its reasonable best efforts to make such filings and seek such regulatory consents and approvals as are necessary so that the
shares of US Gold Common Stock to be issued to holders of Exchangeable Shares pursuant to the terms of the Share Provisions, the Voting and Exchange Trust Agreement and this Agreement will be issued
in compliance with the applicable securities Laws in Canada and the United States and may be freely traded thereafter (other than by reason of a holder being a "control person" of US Gold for purposes
of Canadian federal, provincial or territorial securities Laws or by holders who are Affiliates of US Gold within the meaning of U.S. securities Laws). US Gold will in good faith expeditiously take
all such actions and do all such things as are reasonably necessary or desirable to cause all shares of US Gold Common Stock to be delivered hereunder to be listed, quoted and posted for trading on
all stock exchanges and quotation systems on which outstanding shares of US Gold Common Stock have been listed by US Gold and remain listed and are quoted or posted for trading at such time. 

        Notwithstanding
any other provision of the Share Provisions, or any term of this Agreement, the Voting and Exchange Trust Agreement or the Plan of Arrangement, no shares of US Gold
Common Stock shall be issued (and US Gold will not be required to issue any shares of US Gold Common Stock) in connection with any liquidation, dissolution or winding-up of Exchangeco, or
any retraction,

Section 10.2 of the Share Provisions:

dividends; or (B) pursuant to any dividend reinvestment plan, scrip dividend or similar arrangement; or

	(ii)
	issue
or distribute rights, options or warrants to the holders of all or substantially all of the then outstanding shares of US Gold Common Stock entitling

evidences of indebtedness or other assets simultaneously to holders of the Exchangeable Shares, provided that, for greater certainty, the above restrictions shall not apply to any securities issued or
distributed by US Gold in order to give effect to and to consummate the transactions contemplated by, and in accordance with, the Arrangement Agreement.  

	(b)
	US
Gold will not without the prior approval of Exchangeco and the prior approval of the holders of the Exchangeable Shares given in accordance with
Section 10.2 of the Share Provisions:

	(i)
	subdivide,
redivide or change the then outstanding shares of US Gold Common Stock into a greater number of shares of US Gold Common Stock; or

combine, consolidate or change the then outstanding shares of US Gold Common Stock into a lesser number of shares of US Gold Common Stock; or

	(iii)
	reclassify
or otherwise change the rights, privileges or other terms of the then outstanding shares of US Gold Common Stock or effect an amalgamation,

(x) Exchangeco is permitted under applicable Law to make the same or an economically equivalent change to, or in the rights of holders of, the Exchangeable Shares, and (y) the
same or an economically equivalent change is made simultaneously to, or in the rights of the holders of, the Exchangeable Shares, provided that, for greater certainty, the above restrictions shall not
apply to any securities issued or distributed by US Gold in order to give effect to and to consummate the transactions contemplated by, and in accordance with, the Arrangement Agreement. 

	(c)
	US
Gold will ensure that the record date for any event referred to in Section 2.7(a) or Section 2.7(b), or (if no record date is applicable
for such event) the effective date for any such event, is not less than ten Business Days after the date on which such event is declared or announced by US Gold (with simultaneous notification thereof
by US Gold to Exchangeco).

	(d)
	The
board of directors of Exchangeco shall determine, acting in good faith and in its sole discretion (with the assistance of such reputable and qualified
independent financial advisors and/or other experts as the board may require), economic equivalence for the purposes of any event referred to in Section 2.7(a) or Section 2.7(b) and each
such determination shall be conclusive and binding on US Gold. In making each such determination, the following factors shall, without excluding other factors determined by the board of directors of
Exchangeco to be relevant, be considered by the board of directors of Exchangeco:

	(i)
	in
the case of any stock dividend or other distribution payable in shares of US Gold Common Stock, the number of such shares issued in proportion to the
number of shares of US Gold Common Stock previously outstanding;

	(ii)
	in
the case of the issuance or distribution of any rights, options or warrants to subscribe for or purchase shares of US Gold Common Stock (or securities

Market Price, the volatility of the shares of US Gold Common Stock and the term of any such instrument;

	(iii)
	in
the case of the issuance or distribution of any other form of property (including any shares or securities of US Gold of any class other than shares of
US Gold Common Stock, any rights, options or warrants other than those referred to in Section 2.7(d)(ii), any evidences of indebtedness of US Gold or any assets of US Gold), the relationship
between the fair market value (as determined by the board of directors of Exchangeco in the manner above contemplated) of such property to be issued or distributed with respect to each outstanding
share of US Gold Common Stock and the Current Market Price;

	(iv)
	in
the case of any subdivision, redivision or change of the then outstanding shares of US Gold Common Stock into a greater number of shares of US Gold
Common Stock or the reduction, combination, consolidation or change of the then outstanding shares of US Gold Common Stock into a lesser number of shares of US Gold Common Stock or any amalgamation,
merger, reorganization or other transaction affecting the US Gold Common Stock, the effect thereof upon the then outstanding shares of US Gold Common Stock; and

	(v)
	in
all such cases, the general taxation consequences of the relevant event to holders of Exchangeable Shares compared to holders of US Gold Common Stock
(including to the extent that such consequences may differ as a result of differences between taxation Laws of Canada and the United States) except for any differing consequences arising as a result
of differing marginal taxation rates and without regard to the individual circumstances of holders of Exchangeable Shares. 

7

 

	(e)
	Exchangeco
agrees that, to the extent required, upon due notice from US Gold, Exchangeco will use its best efforts to take or cause to be taken such steps
as may be necessary for the purposes of ensuring that appropriate dividends are paid or other distributions are made by Exchangeco, or subdivisions, redivisions or changes are made to the Exchangeable
Shares, in order to implement the required economic equivalence with respect to the shares of US Gold Common Stock and the Exchangeable Shares as provided for in this Section 2.7. 

2.8   Tender Offers  

        In the event that a cash offer, share exchange offer, issuer bid, take-over bid or similar transaction with respect to US Gold Common Stock (an
"Offer") is proposed by US Gold or is proposed to US Gold or its shareholders and is recommended by the board of directors of US Gold, or is otherwise
effected or to be effected with the consent or approval of the board of directors of US Gold, and the Exchangeable Shares are not redeemed by Exchangeco or purchased by Callco pursuant to the
Redemption Call Right, US Gold and Exchangeco will use reasonable best efforts (to the extent, in the case of an Offer by a third party, within its control) expeditiously and in good faith to take all
such actions and do all such things as are necessary or desirable to enable and permit holders of Exchangeable Shares to participate in such Offer to the same extent and on an economically equivalent
basis as the holders of shares of US Gold Common Stock, without discrimination. Without limiting the generality of the foregoing, US Gold and Exchangeco will use reasonable best efforts expeditiously
and in good faith to ensure that holders of Exchangeable Shares may participate in each such Offer without being required to retract Exchangeable Shares as against Exchangeco (or, if so required, to
ensure that any such retraction, shall be effective only upon, and shall be conditional upon, the closing of such Offer and only to the extent necessary to tender or deposit to the Offer). Nothing
herein shall affect the right of Exchangeco to redeem, or US Gold or Callco to purchase pursuant to the Redemption Call Right, Exchangeable Shares in the event of a US Gold Control Transaction. 

2.9   US Gold and Affiliates Not To Vote Exchangeable Shares  

        US Gold and Callco each covenant and agree that it will appoint and cause to be appointed proxyholders with respect to all Exchangeable Shares held by it and its
Subsidiaries for the sole purpose of attending each meeting of holders of Exchangeable Shares in order to be counted as part of the quorum for each such meeting. Each of US Gold and Callco further
covenants and agrees that it will not, and will cause its Subsidiaries not to, exercise any voting rights that may be exercisable by holders of Exchangeable Shares from time to time pursuant to the
Share Provisions or pursuant to the provisions of the ABCA (or any successor or other corporate statute by which Exchangeco may in the future be governed) with respect to any Exchangeable Shares held
by it or by its Subsidiaries in respect of any matter considered at any meeting of holders of Exchangeable Shares, provided however, for further clarity, that this Section 2.9 shall not in any
way restrict Callco's right to vote its common shares of Exchangeco in accordance with the Share Provisions. 

2.10 Stock Exchange Listing  

        US Gold covenants and agrees in favour of Exchangeco that US Gold will use its reasonable best efforts to maintain a listing of the Exchangeable Shares on the
Toronto Stock Exchange or another designated stock exchange in Canada for the purposes of the Tax Act. 

2.11 Issue of Additional Shares  

        During the term of this Agreement, US Gold will not issue any Special Voting Shares other than the one Special Voting Share to be issued to the Trustee. 

8

 

2.12 Ownership of Outstanding Shares  

        Without the prior approval of Exchangeco and the prior approval of the holders of the Exchangeable Shares given in accordance with Section 10.2 of the
Share Provisions, US Gold covenants and agrees in favour of Exchangeco that, as long as any outstanding Exchangeable Shares are owned by Non-Affiliated Holders, US Gold will be and remain
the direct or indirect beneficial owner of all issued and outstanding common shares in the capital of Exchangeco and Callco. Notwithstanding the foregoing, US Gold shall not be in violation of this
Section 2.12 if any person or group of persons acting jointly or in concert acquires all or substantially all of the assets of US Gold or the shares of US Gold Common Stock pursuant to any
merger of US Gold pursuant to which US Gold was not the surviving corporation. 

2.13 Ordinary Market Purchases  

        For greater certainty, nothing contained in this Agreement, including without limitation the obligations of US Gold contained in Section 2.8, shall limit
the ability of US Gold (or any of its Subsidiaries (including without limitation, Callco or Exchangeco) to make ordinary market purchases of shares of US Gold Common Stock in accordance with
applicable Laws and regulatory or stock exchange requirements. 

2.14 Due Performance  

        On and after the Effective Date, US Gold, Callco and Exchangeco shall duly and timely perform all of their obligations under the Share Provisions.

otherwise) whereby all or substantially all of its undertaking, property and assets would become the property of any other person or, in the case of a merger, of the continuing corporation resulting
therefrom unless, but may do so if: 

	(a)

other Person or continuing corporation (the "US Gold Successor") by operation of Law, becomes, without
more, bound by the terms and provisions of this Agreement or, if not so bound, executes, prior to or contemporaneously with the consummation of such transaction, an agreement supplemental hereto and
such other instruments (if any) as are necessary or advisable to evidence the assumption by the US Gold Successor of liability for all moneys payable and property deliverable hereunder and the
covenant of such US Gold Successor to pay and deliver or cause to be delivered the same and its agreement to observe and perform all the covenants and obligations of US Gold under this Agreement; and

	(b)

transaction shall be upon such terms and conditions as substantially to preserve and not to impair in any material respect any of the rights, duties,
powers and authorities of the other parties hereunder or the holders of Exchangeable Shares. 

3.2   Vesting of Powers in Successor  

        Whenever the conditions of Section 3.1 have been duly observed and performed, the parties, if required by Section 3.1, shall execute and deliver the
supplemental agreement provided for in Section 3.1(a) and thereupon the US Gold Successor and such other person that may then be the issuer of the shares of US Gold Common Stock shall possess
and from time to time may exercise each and every right and power of US Gold under this Agreement in the name of US Gold or otherwise 

9

 

and
any act or proceeding by any provision of this Agreement required to be done or performed by the board of directors of US Gold or any officers of US Gold may be done and performed with like force
and effect by the directors or officers of such US Gold Successor. 

3.3   Wholly-Owned Subsidiaries  

        Nothing herein shall be construed as preventing the amalgamation or merger of any direct or indirect wholly-owned Subsidiary of US Gold with or into US Gold or
the winding-up, liquidation or dissolution of any direct or indirect wholly-owned Subsidiary of US Gold, provided that all of the assets of such Subsidiary are transferred to US Gold or
another direct or indirect wholly-owned Subsidiary of US Gold, and any such transactions are expressly permitted by this Article 3. 

3.4   Successor Transaction  

        Notwithstanding the foregoing provisions of Article 3, in the event of a US Gold Control Transaction: 

	(a)
	in
which US Gold merges or amalgamates with, or in which all or substantially all of the then outstanding shares of US Gold Common Stock are acquired by,
one or more other corporations to which US Gold is, immediately before such merger, amalgamation or acquisition, "related" within the meaning of the Tax Act (otherwise than by virtue of a right
referred to in paragraph 251(5)(b) thereof);

	(b)
	which
does not result in an acceleration of the Redemption Date in accordance with paragraph (b) of that definition; and

	(c)
	in
which all or substantially all of the then outstanding shares of US Gold Common Stock are converted into or exchanged for shares or rights to receive
such shares (the "Other Shares") of another corporation (the "Other Corporation") that, immediately
after such US Gold Control Transaction, owns or controls, directly or indirectly, US Gold, 

then
all references herein to "US Gold" shall thereafter be and be deemed to be references to "Other
Corporation" and all references herein to shares of "US Gold Common Stock" shall thereafter be and be deemed to be references to
"Other Shares" (with appropriate adjustments, if any, as are required to result in a holder of Exchangeable Shares on the exchange, redemption or
retraction of such shares pursuant to the Share Provisions or Article 8 of the Plan of Arrangement or exchange of such shares pursuant to the Voting and Exchange Trust Agreement immediately
subsequent to the US Gold Control Transaction being entitled to receive that number of Other Shares equal to the number of Other Shares such holder of Exchangeable Shares would have received if the
exchange, redemption or retraction of such shares pursuant to the Share Provisions or Article 8 of the Plan of Arrangement, or exchange of such shares pursuant to the Voting and Exchange Trust
Agreement had occurred immediately prior to the US Gold Control Transaction and the US Gold Control Transaction was completed), but subject to subsequent adjustments to reflect any subsequent changes
in the share capital of the issuer of the Other Shares, including without limitation, any subdivision, consolidation or reduction of share capital, without any need to amend the terms and conditions
of the Exchangeable Shares and without any further action required.

  ARTICLE 4
  GENERAL    
    

4.1   Term  

        This Agreement shall come into force and be effective as of the date hereof and shall terminate and be of no further force and effect at such time as no
Exchangeable Shares (or securities or rights convertible into or exchangeable for or carrying rights to acquire Exchangeable Shares) are held by Non-Affiliated Holders. 

4.2   Changes in Capital of US Gold and Exchangeco  

        Notwithstanding the provisions of Section 4.4 hereof, at all times after the occurrence of any event contemplated pursuant to Section 2.7 and
Section 2.8 hereof or otherwise, as a result of which either the shares of US Gold Common Stock or the Exchangeable Shares or both are in any way changed, this Agreement shall forthwith be
amended and modified as necessary in order that it shall apply with full force and effect, mutatis mutandis, to all new securities into which the shares of US Gold Common Stock or the Exchangeable
Shares or both are so changed and the parties hereto shall execute and deliver a supplemental agreement in writing giving effect to and evidencing such necessary amendments and modifications. 

4.3   Severability  

        Notwithstanding the provisions of Section 4.4 hereof, if any term or other provision of this Agreement is invalid, illegal or incapable of being enforced
by any rule or Law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the
transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being
enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that
the transactions contemplated hereby are fulfilled to the fullest extent possible. 

4.4   Amendments, Modifications  

        Subject to Section 4.2, Section 4.3, and Section 4.5, this Agreement may not be amended or modified except by an agreement in writing
executed by Exchangeco, Callco and US Gold and approved by the holders of the Exchangeable Shares in accordance with Section 10.2 of the Share Provisions. 

4.5   Ministerial Amendments  

        Notwithstanding the provisions of Section 4.4 hereof, the parties to this Agreement may in writing at any time and from time to time, without the approval
of the holders of the Exchangeable Shares, amend or modify this Agreement for the purposes of: 

	(a)
	adding
to the covenants of any or all of the parties hereto if the board of directors of each of Exchangeco, Callco and US Gold shall be of the opinion that
such additions will not be prejudicial in any material respect to the rights or interests of the Non-Affiliated Holders as a whole;

	(b)
	evidencing
the succession of US Gold Successors and the covenants of and obligations assumed by each such US Gold Successor in accordance with the
provisions of Article 3;

	(c)
	making
such amendments or modifications not inconsistent with this Agreement as may be necessary or desirable with respect to matters or questions which, in
the opinion of the board of 

11

 

directors
of each of Exchangeco, Callco and US Gold, having in mind the best interests of the Non-Affiliated Holders as a whole, it may be expedient to make, provided that each such board
of directors shall be of the opinion that such amendments or modifications will not be prejudicial in any material respect to the rights or interests of the Non-Affiliated Holders as a
whole; or 

	(d)
	making
such changes or corrections which, on the advice of counsel to Exchangeco, Callco and US Gold, are required for the purpose of curing or correcting
any ambiguity or defect or inconsistent provision or clerical omission or mistake or manifest error, provided that the boards of directors of each of Exchangeco, Callco and US Gold shall be of the
opinion that such changes or corrections will not be prejudicial in any material respect to the rights or interests of the Non-Affiliated Holders as a whole. 

4.6   Meeting to Consider Amendments  

        Exchangeco, at the request of US Gold, shall call a meeting or meetings of the holders of Exchangeable Shares for the purpose of considering any proposed
amendment or modification requiring approval pursuant to Section 4.4 hereof. Any such meeting or meetings shall be called and held in accordance with the bylaws of Exchangeco, the Share
Provisions and all applicable Laws.

        This Agreement shall be binding upon and enure to the benefit of the parties hereto and their respective successors and permitted assigns. 

4.8   Assignment  

        No party hereto may assign this Agreement or any of its rights, interests or obligations under this Agreement or the Arrangement (whether by operation of Law or
otherwise) except that Callco may assign in its sole discretion, any or all of its rights, interests and obligations hereunder to any direct or indirect wholly-owned subsidiary of US Gold.
