$9.8 million in convertible secured promissory notes (the “PriorNotes”).  On November 10,
2008, the parties converted the Prior Notes (including accrued and unpaid
interest thereon) into a Promissory Note dated November 10, 2008 in the

whereby Wits Basin agreed to provide Purchaser security documents, in form and
substance satisfactory to Purchaser, granting Purchaser a security interest in
all of the assets acquired from the use of proceeds for its purchase of the
Prior Notes.  Accordingly, Wits Basin pledged certain shares of common
stock of Wits-China Acquisition Corp, a Minnesota corporation.  On February

Amended and Restated Pledge Agreement (the “Amended Pledge Agreement”) to
provide Purchaser a pledge of the equity interests in two additional wholly
owned subsidiaries of Wits Basin, namely China Global Mining Resources Limited,

remedies provided for in this Agreement or otherwise available to it, all the

affected items of Collateral), and Purchaser may also without notice (except as
specified below) sell the Collateral or any part thereof in one or more parcels
at public or private sale, at any exchange, broker’s board or at any of
Purchaser’s office or elsewhere, for cash, on credit or for future delivery, at

and making settlement or payment of the purchase price for all or any portion of

Collateral payable at such sale. Each purchaser at any such sale shall hold the
property sold absolutely free from any claim or right on the part of any
Pledgor, and such Pledgor by this Agreement waives (to the extent permitted by
law) all rights of redemption, stay, or appraisal that it now has or may at any
time in the future have under any rule of law or statute now existing or
hereafter enacted. Each Pledgor agrees that, to the extent notice of sale shall
be required by law, at least ten (10) calendar days notice to such Pledgor of
the time and place of any public sale or the time after which a private sale is
to be made shall constitute reasonable notification. Purchaser shall not be
obligated to make any sale of Collateral regardless of notice of sale having
been given. Purchaser may adjourn any public or private sale from time to time
by announcement at the time and place fixed therefor, and such sale may, without
further notice, be made at the time and place to which it was so adjourned. To
the maximum extent permitted by law, each Pledgor by this Agreement waives any
claims against Purchaser arising because the price at which any Collateral may
have been sold at such a private sale was less than the price that might have
been obtained at a public sale, even if Purchaser accepts the first offer
received and do not offer such Collateral to more than one offeree.




(b)           Each
Pledgor by this Agreement agrees that any sale or other disposition of the
Collateral conducted in conformity with reasonable commercial practices of
banks, insurance companies, or other financial institutions in the city and
state where Purchaser is located in disposing of property similar to the
Collateral shall be deemed to be commercially reasonable.


8


(c)           Each
Pledgor by this Agreement acknowledges that the sale by Purchaser of any
Collateral pursuant to the terms hereof in compliance with the Securities Act of
1933 as now in effect or as hereafter amended, or any similar statute hereafter
adopted with similar purpose or effect (the “Securities Act”), as well as
applicable “Blue Sky” or other state securities laws may require strict
limitations as to the manner in which Purchaser or any subsequent transferee of
the Collateral may dispose thereof. Each Pledgor acknowledges and agrees that in
order to protect Purchaser’s interest it may be necessary to sell the Collateral
at a price less than the maximum price attainable if a sale were delayed or were
made in another manner, such as a public offering under the Securities Act. Each
Pledgor has no objection to sale in such a manner and agrees that Purchaser
shall have no obligation to obtain the maximum possible price for the
Collateral. Without limiting the generality of the foregoing, such Pledgor
agrees that upon the occurrence and during the continuation of an Event of
Default, Purchaser may, subject to applicable law, from time to time attempt to
sell all or any part of the Collateral by a private placement, restricting the
bidders and prospective Purchaser to those who will represent and agree that
they are purchasing for investment only and not for distribution. In so doing,
Purchaser may solicit offers to buy the Collateral or any part thereof for cash
from a limited number of investors reasonably believed by Purchaser to be
institutional investors or other accredited investors who might be interested in
purchasing the Collateral. If Purchaser shall solicit such offers, then the
acceptance by Purchaser of one of the offers shall be deemed to be a
commercially reasonable method of disposition of the Collateral.




Each
Pledgor acknowledges that there is no adequate remedy at law for failure by it
to comply with the provisions of this Section and that such failure would not be
adequately compensable in damages, and therefore agrees that its agreements
contained in this Section may be specifically enforced.




(d)           EACH
PLEDGOR EXPRESSLY WAIVES TO THE MAXIMUM EXTENT PERMITTED BY LAW: (i) ANY
CONSTITUTIONAL OR OTHER RIGHT TO A JUDICIAL HEARING PRIOR TO THE TIME PURCHASER
DISPOSES OF ALL OR ANY PART OF THE COLLATERAL AS PROVIDED IN THIS SECTION; (ii)
ALL RIGHTS OF REDEMPTION, STAY, OR APPRAISAL THAT IT NOW HAS OR MAY AT ANY TIME
IN THE FUTURE HAVE UNDER ANY RULE OF LAW OR STATUTE NOW EXISTING OR HEREAFTER
ENACTED; AND (iii) EXCEPT AS SET FORTH IN SUBSECTION (a) OF THIS SECTION 10, ANY
REQUIREMENT OF NOTICE, DEMAND, OR ADVERTISEMENT FOR SALE.




(e)           Notwithstanding
any term of this Agreement to the contrary, any rights or actions by Purchaser
under this Section 10 relating to the CGMR BVI shall be subject to the terms of
the Shareholders’ Agreement.




11. 
       Application of Proceeds. 
Upon the occurrence and during the continuance of an Event of Default, any cash
held by Purchaser as Collateral and all cash Proceeds received by Purchaser in
respect of any sale of, collection from, or other realization upon all or any
part of the Collateral pursuant to the exercise by Purchaser of their remedies
as secured creditors as provided in Section 10 shall be applied from time to
time by Purchaser as provided in Section 9-615 of the Uniform Commercial
Code.




12. 
       Indemnity and Expenses. 
Each Pledgor agrees:




(a)           To
indemnify and hold harmless Purchaser and each of their directors, officers,
employees, agents and affiliates from and against any and all claims, damages,
demands, losses, obligations, judgments and liabilities (including, without
limitation, reasonable attorneys’ fees and expenses) in any way arising out of
or in connection with this Agreement or the Secured Obligations, except to the
extent the same shall arise as a result of the gross negligence or willful
misconduct of the party seeking to be indemnified; and


9


(b)           To
pay and reimburse Purchaser upon demand for all reasonable costs and expenses
(including, without limitation, reasonable attorneys’ fees and expenses) that
Purchaser may incur in connection with (i) the custody, use or preservation of,
or the sale of, collection from or other realization upon, any of the
Collateral, including the reasonable expenses of re-taking, holding, preparing
for sale or lease, selling or otherwise disposing of or realizing on the
Collateral, (ii) the exercise or enforcement of any rights or remedies granted
under this Agreement or under any of the other Investment Documents or otherwise
available to them (whether at law, in equity or otherwise), or (iii) the failure
by Pledgor to perform or observe any of the provisions hereof. The provisions of
this Section shall survive the execution and delivery of this Agreement, the
repayment of any of the Secured Obligations, and the termination of this
Agreement or any other Investment Document.




13. 
       Duties of Purchaser.  The
powers conferred on Purchaser under this Agreement are solely to protect their
interests in the Collateral and shall not impose on them any duty to exercise
such powers. Except as provided in Section 9-207 of the Uniform Commercial Code,
Purchaser shall have no duty with respect to the Collateral or any
responsibility for taking any necessary steps to preserve rights against any
Persons with respect to any Collateral.




14. 
       Amendments; etc.No
amendment or waiver of any provision of this Agreement nor consent to any
departure by any Pledgor from this Agreement shall in any event be effective
unless the same shall be in writing and signed by Purchaser and such Pledgor,
and then such waiver or consent shall be effective only in the specific instance
and for the specific purpose for which given. No failure on the part of
Purchaser to exercise, and no delay in exercising any right under this
Agreement, any other Investment Document, or otherwise with respect to any of
the Secured Obligations, shall operate as a waiver thereof; nor shall any single
or partial exercise of any right under this Agreement, any other Investment
Document, or otherwise with respect to any of the Secured Obligations preclude
any other or further exercise thereof or the exercise of any other right. The
remedies provided for in this Agreement or otherwise with respect to any of the
Secured Obligations are cumulative and not exclusive of any remedies provided by
law.




15. 
       Notices.  Unless
otherwise specifically provided in this Agreement, all notices shall be in

16. 
       Continuing Security
Interest.  This Agreement shall create a continuing security
interest in the Collateral and shall: (a) remain in full force and effect until
the indefeasible payment in full of the Secured Obligations; (b) be binding upon
each Pledgor and its successors and assigns; and (c) inure to the benefit of
Purchaser and their successors, transferees, and assigns. Upon the indefeasible
payment in full of the Secured Obligations, the security interests granted in
this Agreement shall automatically terminate and all rights to the Collateral
shall revert to Pledgors. Upon any such termination, Purchaser will, at each
Pledgor’s expense, execute and deliver to such Pledgor such documents as such
Pledgor shall reasonably request to evidence such termination. Such documents
shall be prepared by such Pledgor and shall be in form and substance reasonably
satisfactory to Purchaser.




17. 
       Security Interest
Absolute.  To the maximum extent permitted by law, all rights of
Purchaser, all security interests under this Agreement, and all obligations of
Pledgors under this Agreement, other than under the terms of the Shareholders'
Agreement where applicable, shall be absolute and unconditional irrespective
of:




(a)           any
lack of validity or enforceability of any of the Secured Obligations or any
other agreement or instrument relating thereto, including any of the Investment
Documents;




(b)           any
change in the time, manner, or place of payment of, or in any other term of, all
or any of the Secured Obligations, or any other amendment or waiver of or any
consent to any departure from any of the Investment Documents, or any other
agreement or instrument relating thereto;


11


(c)           any
exchange, release, or non-perfection of any other collateral, or any release or
amendment or waiver of or consent to departure from any guaranty for all or any
of the Secured Obligations; or




(d)           any
other circumstances that might otherwise constitute a defense available to, or a
discharge of, any Pledgor.




18. 
       Construction.  Section
and subsection headings in this Agreement are included in this Agreement for
convenience of reference only and shall not constitute a part of this Agreement
or be given any substantive effect.  Unless the context of this Agreement
clearly requires otherwise, references to the plural include the singular and to
the singular include the plural, the part includes the whole, the term
“including” is not limiting, and the term “or” has, except where otherwise
indicated, the inclusive meaning represented by the phrase “and/or.” The words
“hereof,” “herein,” “hereby,” “hereunder,” and other similar terms in this
Agreement refer to this Agreement as a whole and not exclusively to any
particular provision of this Agreement. Article, section, subsection, exhibit,
and schedule references are to this Agreement unless otherwise specified. All of
the exhibits or schedules attached to this Agreement shall be deemed
incorporated in this Agreement by reference. Any reference to any of the
following documents includes any and all alterations, amendments, restatements,
extensions, modifications, renewals, or supplements thereto or thereof, as
applicable: this Agreement or any of the other Investment Documents.  No
inference in favor of, or against, any party shall be drawn from the fact that
such party has drafted any portion of this Agreement, each party having been
represented by counsel of its choice in connection with the negotiation and
preparation of this Agreement and the other Investment Documents.




19. 
       Interpretation.  Neither
this Agreement nor any uncertainty or ambiguity in this Agreement shall be
construed or resolved against Purchaser or any Pledgor, whether under any rule
of construction or otherwise. On the contrary, this Agreement has been reviewed
by both of the parties and their respective counsel and shall be construed and
interpreted according to the ordinary meaning of the words used so as to fairly
accomplish the purposes and intentions of the parties to this
Agreement.




20. 
       Severability.  In case
any provision in or obligation under this Agreement shall be invalid, illegal or
unenforceable in any jurisdiction, the validity, legality and enforceability of
the remaining provisions or obligations, or of such provision or obligation in
any other jurisdiction, shall not in any way be affected or impaired
thereby.




21. 
       Counterparts; Facsimile
Execution.  This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original and all of which
together shall constitute one and the same Agreement. Delivery of an executed
counterpart of this Agreement by facsimile shall be equally as effective as
delivery of an original executed counterpart of this Agreement. Any party
delivering an executed counterpart of this Agreement by facsimile also shall
deliver an original executed counterpart of this Agreement but the failure to
deliver an original executed counterpart shall not affect the validity,
enforceability, or binding effect of this Agreement.




22. 
       Waiver of Marshaling. 
Each of the Pledgors and Purchaser acknowledge and agree that in exercising any
rights under or with respect to the Collateral: (a) Purchaser is under no
obligation to marshal any Collateral; (b) may, in their absolute discretion,
realize upon the Collateral in any order and in any manner they so elect; and
(c) may, in their absolute discretion, apply the proceeds of any or all of the
Collateral to the Secured Obligations in any order and in any manner they so
elect. Each Pledgor and Purchaser waive any right to require the marshaling of
any of the Collateral.




12


23. 
       Conflict Among
Provisions.  In the event of a conflict between the terms, covenants
and conditions of this Agreement and those of any other Investment Document
(unless otherwise specifically provided), the terms, covenants and conditions of
the document which shall enlarge the interest of Purchaser in the Collateral,
afford Purchaser greater financial benefits or financial security or better
assure payment of the Obligations in full, shall control; provided, however,
that in the event of a conflict between any provision of this Agreement and the
provisions of any other document, instrument or agreement which grants Purchaser
a security interest in all or any part of the Pledged Interest, the provisions
of this Agreement shall control.




24. 
       Sole and Absolute Discretion of
Purchaser. Whenever pursuant to this Agreement (a) Purchaser exercises
any right given to them to consent, approve or disapprove, (b) any arrangement,
document, item or term is to be satisfactory to Purchaser, or (c) any other
decision or determination is to be made by Purchaser, the decision of Purchaser
to consent, approve or disapprove, all decisions that arrangements, documents,
items, or terms are satisfactory or not satisfactory and all other decisions and
determinations made by Purchaser, shall be in the sole and absolute discretion
of Purchaser and shall be final and conclusive, except as may be otherwise
expressly and specifically provided in this Agreement.




25. 
       Consent to Forum. AS PART OF
THE CONSIDERATION FOR NEW VALUE THIS DAY RECEIVED, EACH PLEDGOR BY THIS
AGREEMENT CONSENTS TO THE JURISDICTION OF ANY STATE COURT LOCATED WITHIN JOHNSON
COUNTY, KANSAS OR FEDERAL COURT IN THE DISTRICT COURT OF KANSAS, AND CONSENTS
THAT ALL SERVICE OF PROCESS BE MADE BY CERTIFIED OR REGISTERED MAIL DIRECTED TO
SUCH PLEDGOR AT THE ADDRESS STATED IN THE PURCHASE AGREEMENT AND SERVICE SO MADE
SHALL BE DEEMED TO BE COMPLETED UPON ACTUAL RECEIPT THEREOF.  EACH PLEDGOR
WAIVES ANY OBJECTION TO JURISDICTION AND VENUE OF ANY ACTION INSTITUTED AGAINST
IT AS PROVIDED IN THIS AGREEMENT AND AGREES NOT TO ASSERT ANY DEFENSE BASED ON
LACK OF JURISDICTION OR VENUE.  EACH PLEDGOR FURTHER AGREES NOT TO ASSERT
AGAINST PURCHASER (EXCEPT BY WAY OF A DEFENSE OR COUNTERCLAIM IN A PROCEEDING
INITIATED BY PURCHASER) ANY CLAIM OR OTHER ASSERTION OF LIABILITY WITH RESPECT
TO THE INVESTMENT DOCUMENTS, PURCHASER’S CONDUCT OR OTHERWISE IN ANY
JURISDICTION OTHER THAN THE FOREGOING JURISDICTIONS.




26. 
       Waiver of Jury Trial. TO THE FULLEST EXTENT PERMITTED BY
LAW, AND AS SEPARATELY BARGAINED-FOR CONSIDERATION TO PURCHASER, EACH PLEDGOR BY
THIS AGREEMENT WAIVES ANY RIGHT TO TRIAL BY JURY (WHICH PURCHASER ALSO WAIVES)
IN ANY ACTION, SUIT, PROCEEDING OR COUNTERCLAIM OF ANY KIND ARISING OUT OF OR
OTHERWISE RELATING TO ANY OF THE INVESTMENT DOCUMENTS, THE OBLIGATIONS, THE
PLEDGED INTEREST, OR PURCHASER’S CONDUCT IN RESPECT OF ANY OF THE
FOREGOING.




27. 
         Entire Agreement. This
agreement, the Purchase Agreement, Amendment No. 4, the Third Amended Note and
the Second Amended and Restated Security Agreement between the parties thereto
dated on or around the date of the Agreement (i) constitute the final expression
of the agreement between Pledgors and Purchaser concerning the Pledge; and (ii)
may not be contradicted by evidence of any prior or contemporaneous oral
agreements or understandings between Pledgors and Purchaser.  Neither
this agreement nor any of the terms hereof may be terminated, amended,
supplemented, waived or modified orally, but only by an instrument in writing
executed by the party against which enforcement of the termination, amendment,
supplement, waiver or modification is sought.
