      precautions to prevent inadvertent disclosure of any Confidential
      Information disclosed by the Company to him. This prohibition includes,
      but is not limited to, disclosing or confirming the fact that any
      similarity exists between the Confidential Information and any other
      information.

      At all times during and subsequent to the Contractor's
      retainer with the Company, neither the Contractor nor Finkelstein will
      use, copy, transfer or destroy any Confidential Information other than as
      necessary in carrying out the Consulting Services, or as may be required
      by applicable law or process of discovery, without first obtaining the
      Company's consent and the Contractor and Finkelstein will each take all
      reasonable precautions to prevent inadvertent use, copying, transfer or
      destruction of any Confidential Information disclosed by the Company to
      either or both of them.

10

	 	6.2.3 	
      Within ten (10) business days after the termination of

      administered by the Company in its custody, including without limitation
      all Confidential Information that is embodied in any form, whether in hard
      copy or on electronic media.

	 	 	 
	 	6.2.4 	
      The provisions of this Section 6 shall survive the

      limiting the generality of the foregoing, the Contractor and Finkelstein
      each hereby consents to an injunction being granted by a court of
      competent jurisdiction in the event that the Contractor or Finkelstein is
      in breach of any of the provisions stipulated in this Section 6. The

      breach of any of the said provisions.

	 	 
	6.4 	
      The Contractor's obligations under this Section 6 will
      remain in effect in accordance with their terms and continue in full force
      and effect despite any breach, repudiation, alleged breach or repudiation,
      or termination of this Agreement. Without limiting the foregoing, the
      Contractor and Finkelstein each agrees that at all times during and
      subsequent to the provision of services to the Company, neither of the
      Contractor or Finkelstein will use or take advantage of the Confidential
      Information for the purpose of:

	 	6.4.1

SCHEDULE B 

INDEMNIFICATION AGREEMENT 

THIS AGREEMENT (“Agreement”) made and entered into as of
January 1, 2012 by and between ARGENTEX MINING CORPORATION (the
“Company”), a corporation continued under the laws of the Province of
British Columbia and JEFFREY FINKELSTEIN, a resident of British Columbia (the
“Indemnitee”). 

RECITALS: 

WHEREAS, competent persons
have become more reluctant to serve publicly-held corporations as directors or
officers unless they are provided with adequate protection through insurance or
adequate indemnification against inordinate risks of claims and actions against
them arising out of their service to, and activities on behalf of, the
corporation; and WHEREAS, it is reasonable and prudent for the Company
contractually to indemnify such persons to the extent set forth in this
Agreement in an effort to give them additional incentive to serve or continue to
serve the Company. 

NOW, THEREFORE, in
consideration of the premises and the covenants contained herein, the Company
and Indemnitee hereby covenant and agree as follows: 

1.                  Services by Indemnitee.
This Agreement shall not be deemed an employment contract between the Company
(or any of its subsidiaries) and Indemnitee, and it shall continue in force
after Indemnitee has ceased to serve as a director or officer of the Company.

2.                  Indemnity. The Company
will indemnify Indemnitee under this Section 2 if, by reason of Indemnitee’s
Corporate Status (as hereinafter defined) or by reason of any act done or not
done by Indemnitee by reason of or on account of Indemnitee’s Corporate Status,
Indemnitee is made a party to or a participant in any Proceeding (as hereinafter
defined), other than a Proceeding by or in the right of the Company.
Notwithstanding the foregoing, this indemnity will not apply to any such
Proceeding unless Indemnitee acted in Good Faith. 

3.                  Indemnification for Other
Expenses. In addition to the Indemnity provided in Section 2, above, the
Company will indemnify Indemnitee against all Expenses (as hereinafter defined)
actually and reasonably incurred or suffered by Indemnitee or on Indemnitee’s
behalf if Indemnitee is, by reason of Indemnitee’s Corporate Status, a witness
or otherwise involved in any manner in any Proceeding to which Indemnitee is not
a party; provided that Indemnitee shall not be entitled to be compensated or
reimbursed for the value of Indemnitee's time spent as such unless (i)
Indemnitee no longer serves as an officer, director, employee or agent of the
Company and (ii) Indemnitee has spent more than ten business days as a witness
or other non-party participant in such Proceeding by reason of Indemnitee’s
prior Corporate Status. If Indemnitee is made a party to such Proceeding, then
the provisions of Section 2, above, will apply in accordance with the terms
thereof. 

4.                  Advancement of
Expenses. If permitted by law, the Company may elect to advance all or any
portion of Expenses incurred by or on behalf of Indemnitee in connection with
any Proceeding referred to in Section 2 or 3, above, within ten days after the
receipt by the Company of a statement or statements from Indemnitee requesting
such advance or advances from time to time, together with an undertaking from
the Indemnitee, in form and substance satisfactory to the Company in its sole
discretion, that it will repay such advance or advances to the Company if it is
ultimately determined that the advance(s) were prohibited by law or that the
Indemnitee is not entitled to indemnity in respect of that Proceeding or those
Expenses. Such statement or statements must reasonably evidence the Expenses
incurred by Indemnitee. In furtherance of the foregoing, Indemnitee hereby
undertakes to repay any Expenses advanced if it is ultimately determined by
final judgment of a court of competent jurisdiction that Indemnitee is not
entitled to be indemnified against such Expenses. 

2

5.                  Procedure for Determination of Entitlement to
Indemnification. 

(a)                  To obtain
indemnification under this Agreement, Indemnitee must submit to the Company a
written request, including therein or therewith such documentation and
information as is reasonably available to Indemnitee and is reasonably necessary
to determine whether and to what extent Indemnitee is entitled to such
indemnification. The Secretary of the Company will, promptly upon receipt of
such a request for indemnification, advise the Board in writing that Indemnitee
has requested indemnification. 

6.                  Notification and Defense of Proceeding. 

(a) Indemnitee shall
promptly notify the Company in writing upon being served with any summons,
citation, subpoena, complaint, indictment, information or other document
relating to any Proceeding that may be subject to indemnification or advancement
of Expenses pursuant to this Agreement, but subject to the last sentence of
Section 6(c), below, the failure so to notify the Company will not relieve it
from any liability that it may have to Indemnitee. 

(b)                  In the event
Indemnitee notifies the Company of the commencement of a Proceeding, the Company
will be entitled to participate in the Proceeding at its own expense, and except
as otherwise provided below, if the Company so wishes, it may assume the defense
thereof with counsel reasonably satisfactory to Indemnitee. After notice from
the Company to Indemnitee of its election to assume the defense of any
Proceeding, the Company will not be liable to Indemnitee under this Agreement or
otherwise for any Expenses subsequently incurred by Indemnitee in connection
with the defense of such Proceeding other than reasonable costs of investigation
or as otherwise provided below. Indemnitee shall have the right to retain
Indemnitee’s own counsel in such Proceeding, but Indemnitee shall be obligated
to pay all Expenses related thereto incurred by Indemnitee after notice from the
Company of its assumption of the defense unless: (i) the retention of counsel by
Indemnitee has been authorized by the Company, (ii) there is a conflict of
interest between Indemnitee and the Company in the defense of the Proceeding, or
(iii) the Company shall not within 60 calendar days have retained counsel to
assume the defense of such Proceeding, in each of which cases all Expenses
incurred by Indemnitee in connection with such Proceeding shall be borne by the
Company. In the event separate counsel is retained by Indemnitee pursuant to
this Section 6(b), the Company shall cooperate with Indemnitee with respect to
the defense of the Proceeding, including making documents, witnesses and other
reasonable information related to the defense available to Indemnitee and such
separate counsel pursuant to joint-defense agreements or confidentiality
agreements, as appropriate. Notwithstanding any provision herein to the
contrary, the Company shall not be entitled to assume the defense of any
Proceeding brought by or on behalf of the Company. 

3

(c)                  The Company shall not
be liable to indemnify Indemnitee under this Agreement or otherwise for any
amounts paid in settlement of any Proceeding effected without the Company’s
express prior written consent. The Company shall not settle any Proceeding in
any manner that would impose any penalty, liability or limitation on Indemnitee
without Indemnitee’s prior written consent; provided that the Company shall not
be required to obtain the consent of Indemnitee to the settlement of any
Proceeding the Company has undertaken to defend if the settlement grants
Indemnitee a complete and unqualified release in respect of the potential
liability. The Company shall not be liable for any amount paid by Indemnitee in
settlement of any Proceeding that is not defended by the Company unless the
Company has consented to such settlement. Neither the Company nor Indemnitee
will unreasonably withhold, condition or delay their consent to any proposed
settlement. The Company shall have no obligation to indemnify Indemnitee under
this Agreement with regard to any judicial award issued in a Proceeding, or any
related Expenses of Indemnitee, if the Company was not given a reasonable and
timely opportunity, at its expense, to participate in the defense of such
Proceeding, except to the extent that the Company was not materially prejudiced
thereby. 

7.                  Subrogation. 

(a)                  In the event of any
payment under this Agreement, the Company shall be subrogated to the extent of
such payment to all of the rights of recovery of Indemnitee, who shall execute
all documents required and take all actions necessary to secure such rights,
including execution of such documents as are necessary to enable the Company to
bring suit to enforce such rights. 

(b)                  The Company shall not
be liable under this Agreement to make any payment of amounts otherwise
indemnifiable (or for which advancement is provided hereunder) hereunder if and
to the extent that Indemnitee has already received payment of such amounts under
any insurance policy, contract, agreement or otherwise. 

(c)                  The Company’s
obligation to indemnify or advance Expenses hereunder to Indemnitee due to the
fact that Indemnitee is or was serving at the request of the Company as a
director, officer, employee or agent of any other corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise shall be reduced
by any amount Indemnitee has already received as indemnification or advancement
of expenses from such other corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise.

8.                  Duration of Agreement.
This Agreement shall continue until and terminate upon the later of: (i) the
expiration of the applicable limitations periods as to all possible claims in
respect of which Indemnitee is granted rights of indemnification or advancement
of Expenses hereunder upon commencement of a related Proceeding, or (ii) the
final termination of any Proceeding then pending in respect of which Indemnitee
is granted rights of indemnification or advancement of Expenses hereunder. This
Agreement shall be binding upon the Company and its successors and assigns and
shall inure to the benefit of Indemnitee and Indemnitee’s heirs, executors and
administrators. 

9.                  Severability. If any
provision or provisions of this Agreement shall be held to be invalid, illegal
or unenforceable for any reason whatsoever: (i) the validity, legality and
enforceability of the remaining provisions of this Agreement (including without
limitation each satisfactory to the Company in its sole discretion, that it will
repay such advance or advances to the Company if it is ultimately determined
that the advance(s) were prohibited by law or that the Indemnitee is not
entitled to indemnity in respect of that Proceeding or those Expenses. Such
statement or statements must reasonably evidence the Expenses incurred by
Indemnitee. In furtherance of the foregoing, Indemnitee hereby undertakes to
repay any Expenses advanced if it is ultimately determined by final judgment of
a court of competent jurisdiction that Indemnitee is not entitled to be
indemnified against such Expenses. 

4

10.                  Exception to Right of Indemnification or Advancement of
Expenses. Notwithstanding any other provision of this Agreement, Indemnitee
shall not be entitled to indemnification or advancement of Expenses under this
Agreement with respect to any Proceeding brought by Indemnitee, or any claim
therein, unless the bringing of such Proceeding or making of such claim shall
have been approved by the Board. 

11.                  Identical
Counterparts. This Agreement may be executed in one or more counterparts,
each of which shall for all purposes be deemed to be an original but all of
which together shall constitute one and the same Agreement. Only one such
counterpart signed by the party against whom enforceability is sought needs to
be produced to evidence the existence of this Agreement. 

12.                  Headings. The headings

not be deemed to constitute part of this Agreement or to affect the construction
thereof.

AMENDING AGREEMENT 

THIS AMENDING AGREEMENT (“Amending Agreement”) is dated
and effective as of May 1, 2015. 

BETWEEN: 

ARGENTEX MINING CORPORATION, a
company continued under the laws of British Columbia with an office at Suite

(the “Company”) 

AND: 

JBD CONSULTING LTD., a company

AND: 

JEFFREY FINKELSTEIN, an

Regent Street, Richmond, British Columbia Canada V7E 2N1 

("Finkelstein") 

WHEREAS: 

A.                  The Company, the Contractor and Finkelstein (collectively
referred to as the “Parties”) entered into an Independent Contractor
Agreement dated effective January 1, 2014 (the “Original Agreement”); and

B.                  In light of economic conditions currently affecting the
Company and the industry in which it operates, the Parties wish to amend the
Original Agreement to effect a temporary reduction in the Consulting Fee. 

NOW THEREFORE for good and valuable consideration, the
receipt and sufficiency of which is hereby acknowledged, the Parties do hereby
covenant and agree as follows: 

	1. 	
      Definitions. Words that are capitalized in this
      Amending Agreement but not defined in this Amending Agreement are defined
      in the Original Agreement and, unless the context clearly requires
      otherwise, shall have the meaning attributed to them in the Original
      Agreement.

	 	 
	2. 	
      Reduction of Consulting Fee. During the period
      beginning May 1, 2015 and ending on the earlier to occur of (a) the
      completion of an event that constitutes a Change of Control and (b) April
      30, 2016, the amount of the Consulting Fee is decreased from $15,000 per
      month to $11,250 per month. Notwithstanding the foregoing, the temporary
      reduction of the Consulting Fee provided for in this Amending Agreement
      shall not affect the calculation of termination benefits in the event the
      Original Agreement is terminated by the Company as provided in Section 4.3
      and 4.4 of the Original Agreement, nor shall it be deemed to be a material
      reduction for purposes of establishing constructive dismissal of the
      Contractor or Finkelstein, to the extent that such concept applies to the
      relationship between the Parties.

	3. 	
      Change of Control. Upon completion of an event
      constituting a Change of Control, the Company shall reimburse the
      Contractor for an amount equal to “X” multiplied by “Y”, where “X” is
      equal to the sum of $3,750 and “Y” is equal to the number of calendar
      months (to a maximum of six calendar months) that have elapsed between May
      1, 2015 and the earlier of (a) the date of the event constituting a Change
      of Control and (b) the date of termination of the Original
    Agreement.

	 	 
	4. 	
      Original Agreement Continues in Effect. Except as
      hereby amended, the Parties agree that the Original Agreement remains in
      full force and effect.

      Columbia and the laws of Canada applicable
therein.
