SECURED PROMISSORY NOTE

	U.S. $4,900,000 	May 31, 2006 

          FOR
  VALUE RECEIVED, the undersigned NORD RESOURCES CORPORATION, a company
  organized under the laws of Delaware (the “Company” or “Borrower”),
  promises to pay to the order of NEDBANK LIMITED, a limited liability

  the principal sum of $4,900,000.00, with simple interest accruing daily from
  the above-referenced date until paid, at a rate of ten percent (10%) per annum.
  Interest shall be paid monthly in cash on the first day of each month commencing
  June 1, 2006. Notwithstanding the foregoing, upon the occurrence of a Default
  and during the continuance of a Default, the principal balance then outstanding
  shall accrue interest at a rate of thirteen percent (13%) per annum.

  this Note is subject, and to which Holder, by acceptance of this Note, agrees:

  Maturity Date. The principal balance hereof, and accrued but unpaid interest
  thereon, shall be due and payable on the earlier of: (a) August 15, 2006; or

  it of the loss, theft, destruction or mutilation of this Note, and (in the case
  of loss, theft or destruction) of reasonably satisfactory indemnification, and
  upon surrender and cancellation of this Note, if mutilated, the Company will
  execute and deliver a new Note of like tenor and date. Any such new Note executed
  and delivered shall constitute an additional contractual obligation on the part
  of the Company, whether or not this Note so lost, stolen, destroyed, or mutilated
  shall be at any time enforceable by anyone.

          3.
  Default.

                    (a)

  any of the following events shall occur (each such event being a “Default”):

	 	(1) 	
      the Company shall fail to pay the principal and accrued
      but unpaid interest of the Note on any date such items are due, provided
      however, the Company shall have a period of three (3) Business Days from
      any such date within which cure a Default on an interest
  payment;

	 	(2) 	
      any representation or warranty made by the Company to
      Holder herein or in any other document, instrument or agreement executed
      by the Company in connection with the Loan (as amended or extended from
      time to time and in effect, each, a “Loan Document,” and collectively,
      with the Note, the “Loan Documents”) shall fail to be true and correct in
      any material respect (provided that the Company shall have a period of
      five (5) Business Days from the date the Company receives written notice
      thereof from the Holder within which to cure such Default(s));

	 	 	 
	 	(3) 	
      the Company shall fail to observe or perform any of the
      covenants, agreements or obligations (excluding the Company’s obligation
      to pay principal and interest as provided herein) contained in the Note or
      any other Loan Document or any other agreement with Holder in any material
      respect (provided that the Company shall have a period of five (5)
      Business Days from the date the Company receives written notice thereof
      from the Holder within which to cure such Default(s));

	 	 	 
	 	(4) 	
      the Company shall institute proceedings to be adjudicated
      bankrupt or insolvent, or the consent by the Company to the institution of
      bankruptcy or insolvency proceedings against it under the Bankruptcy Act,
      or any other applicable federal or state insolvency law, or the consent by
      the Company, or acquiescence in, the filing of any such petition or in the
      appointment of a receiver, liquidator, assignee, trustee, or other similar
      official of the Company, or of any substantial part or its property, or
      the making by the Company of an assignment for the benefit of creditors,
      or the admission by the Company in writing of its inability to pay its
      debts generally as they become due;

	 	 	 
	 	(5) 	
      within sixty (60) days after the commencement of
      proceedings against the Company seeking any bankruptcy, insolvency,
      liquidation, dissolution or similar relief under any present or future
      statute, law or regulation, such action shall not have been dismissed or
      all orders or proceedings thereunder affecting the operations or the
      business of the Company stayed, or the stay of any such order or
      proceedings shall thereafter be set aside, or, within thirty (30) days
      after the appointment without the consent or acquiescence of the Company
      of any trustee, receiver or liquidator of the Company over of all or any
      substantial part of the properties of the Company, such appointment shall
      have not been vacated;

	 	 	 
	 	(6) 	
      the Company shall dissolve or take steps toward
      dissolution;

	 	 	 
	 	(7) 	
      final judgments which exceed an aggregate of $100,000
      shall be rendered against the Company or its subsidiaries and shall not
      have been paid, discharged or vacated within forty-five (45) days after
      entry or filing of such judgments;

	 	(8) 	
      any event of default (as such term is defined under any
      applicable underlying agreement) of any of the Company’s indebtedness in
      excess of $75,000 in the aggregate shall occur or any failure of the
      Company to pay any such indebtedness when due shall occur; and

	 	 	 
	 	(9) 	
      the Deed of Trust (as hereinafter defined) shall for any
      reason (other than pursuant to the terms thereof or by reason of any
      action taken by the Holder and not with the knowledge of the Borrower or
      within its power to control) cease to create a valid and perfected (to the
      extent required thereby or by this Agreement) first priority lien in the
      Johnson Camp Collateral (as hereinafter defined), or the Company asserts
      such failure, provided however, the Company shall have a period of
      ten (10) Business Days within which to cure this deficiency and perfect
      the Holder’s first priority lien in the Johnson Camp
  Collateral.

                    (b)
  Remedies Upon Default. Upon the occurrence, and at any time during the
  continuance of, any Default, Holder, upon notice in writing to the Company,
  may declare all unpaid principal of the Note and the interest thereon to be
  immediately due and payable and the same shall become immediately due and payable
  upon such declaration and Holder may pursue any remedy available to Holder at
  law or in equity; provided, however, that in the event of any
  Default under clauses (4) or (5) above, all unpaid principal hereof and interest
  hereunder shall automatically become immediately due and payable, without the
  need for declaration, presentment, demand, protest, or other notice of any kind.

          4.
  Mandatory Repurchase of Notes. As soon as possible, and in any event
  within five (5) Business Days after the occurrence of a Mandatory Repurchase
  Event (as defined below), the Company shall furnish to Holder written notice
  setting forth in reasonable detail the facts and circumstances underlying such
  Mandatory Repurchase Event. The occurrence of any such Mandatory Repurchase
  Event shall constitute an irrevocable offer by the Company to purchase all of
  the Notes held by Holder, at 101% of the principal amount thereof, on a date
  to be specified by the Company, which date shall be not less than thirty (30)
  days nor more than ninety (90) days after the occurrence of such Mandatory Repurchase
  Event, together with all accrued and unpaid interest on the amount so purchased
  through the date of purchase. Following receipt of any offer to prepay the Notes
  hereunder, Holder shall advise the Company, by written notice, within ten (10)
  days after receipt of such offer, as to whether it desires to sell all, but
  not less than all of the Notes held by it (in integral multiples of $500,000),
  specifying the principal amount of the Notes to be sold by it. If Holder accepts
  such offer but does not specify an amount it wishes to receive, it will be deemed
  to have elected to sell all of the Notes held by it.

          5.
  Mandatory Repurchase Event. “Mandatory Repurchase Event” shall
  mean at any time prior to or after a public offering (i) any person together
  with all affiliates and associates of such person, shall become the beneficial
  owner, directly or indirectly, of securities of the Company representing 51%
  or more of the combined voting power of the Company’s then outstanding
  securities having the right to vote in an election of the Company’s Board
  of Directors; or (ii) 

persons who constitute the Company’s Board of Directors as of the date hereof cease for any reason, including, without limitation, as a result of a tender offer, proxy contest, merger or similar transaction, to constitute at least a majority of
the Company’s Board of Directors; or (iii) the Board of Directors and the stockholders of the Company (if required) shall approve (a) any consolidation or merger of the Company where the stockholders of the Company, immediately prior to the
consolidation or merger, would not, immediately after the consolidation or merger, beneficially own, directly or indirectly, shares representing in the aggregate at least 51% or more of the voting shares of the corporation issuing cash or securities
in the consolidation or merger (or of its ultimate parent corporation, if any), (b) any sale, lease, exchange or other transfer (in one transaction or a series of transactions contemplated or arranged by any party as a single plan) of all or
substantially all of the assets of the Company, (c) any plan or proposal for the liquidation or dissolution of the Company, or (iv) the Company terminates the services of Salman Partners without completing an offering of the Company’s capital
stock.

           6.
  Prepayment.

                     (a)
  Optional Prepayment. The Company may, upon ten (10) days prior written
  notice to Holder, prepay this Note in whole or in part, but in no event less
  than $250,000 for each occurrence of a prepayment, at any time without premium
  or penalty (other than for such premium as is contemplated in Section 4 hereof
  in connection with a mandatory repurchase of this Note); provided, however,
  that the Company shall reimburse Holder for any premiums, penalties or other
  costs incurred by Holder on account of the Company’s prepayment of this
  Note.

                     (b)
  Mandatory Prepayment. For so long as this Note shall be outstanding,
  the Company agrees to apply all funds received by the Company on any of its
  future borrowings or offerings of equity, including without limitation any financings,
  debt offerings, offerings of its equity or debt securities, against the outstanding
  balance due under this Note, except for proceeds of (i) short term unsecured
  working capital facilities but not in excess of $1,000,000 in the aggregate
  at any one time, and (ii) purchase money security interest financings used for
  the acquisition of equipment to be used at the Johnson Camp Mine but not to
  exceed $250,000 in the aggregate at any one time.

           7.
  Notices to Holder. So long as this Note shall be outstanding, (i) if
  the Company shall pay any dividend or make any distribution upon the Common
  Stock or (ii) if the Company shall offer to the holders of Common Stock for
  subscription or purchase by them any share of any class of Capital Stock or
  any other rights or (iii) if any capital reorganization of the Company, reclassification
  of the Capital Stock of the Company, consolidation or merger of the Company
  with or into another corporation, sale, lease or transfer of all or substantially
  all of the property and assets of the Company to another corporation, or voluntary
  or involuntary dissolution, liquidation or winding up of the Company shall be
  effected, then in any such case, the Company shall cause to be mailed by certified
  mail to Holder, at least fifteen (15) days prior the date specified in (x) or
  (y) below, as the case may be, a notice containing a brief description of the
  proposed action and stating the date on which (x) a record is to be taken for
  the purpose of such dividend, distribution or rights, or (y) such reclassification,
  reorganization, consolidation, merger, conveyance, lease, dissolution, liquidation

  the holders 

of Common Stock or other securities shall receive cash or other property deliverable upon such reclassification, reorganization, consolidation, merger, conveyance, dissolution, liquidation or winding up. The Company shall also promptly deliver a
notice to Holder describing any Default of which it has become aware.

           8.
  Gross Up. All payments under this Note by Borrower will be made without
  any deduction or withholding for or on account of any tax or other withholding
  or deduction unless such tax, deduction or withholding is required by any applicable
  law then in effect (a “Required Tax, Deduction or Withholding”).
  If Borrower is so required to deduct or withhold any Required Tax, Deduction
  or Withholding, then Borrower will promptly notify Holder of such requirement
  and: 

                    (a)
  pay to the relevant authorities the full amount of the Required Tax, Deduction
  or Withholding (including the full amount required to be deducted or withheld

  8) promptly upon the earlier of determining that the Required Tax Deduction
  or Withholding is required or receiving notice that such amount has been assessed
  against Holder; 

                    (b)
  promptly forward to Holder an official receipt (or a certified copy), or other

  authorities; and 

                    (c)
  pay to Holder, in addition to the payment to which Holder is otherwise entitled
  under this Note, such additional amount as is necessary to ensure that the net
  amount actually received by Holder will equal the full amount Holder would have
  received had no such Required Tax, Deduction or Withholding been required.

           9.
  Costs. The Company agrees to reimburse Holder for any reasonable legal
  fees or other costs associated with this Note or any of the other Loan Documents,
  but in no event more than Twenty Thousand Dollars ($20,000).

  the aggregate, are not material in amount, and which do not, in the aggregate,

  which consent may be given or denied at Holder’s sole discretion, the Company
  will not become a party to any merger or consolidation, or agree to or effect

  of the Company in connection with such merger or consolidation or (b) any merger
  or consolidation or asset acquisition or stock acquisition which results in
  the acquisition of any business division or operation that is in the Company’s
  current lines of business and that does not result in a change of control of
  the Company or any subsidiary (for purposes hereof, the term “change of
  control” shall be deemed to mean a Mandatory Repurchase Event), provided
  that (i) notwithstanding anything herein to the contrary, only Capital Stock
  of the Company or a subsidiary of the Company may be used to affect any such
  transaction, (ii) the value of the Capital Stock issued in connection with any
  such merger, consolidation or acquisition is not more than the fair market value
  of the stock or assets being acquired (as determined in the reasonable and good
  faith judgment of the Company’s Board of Directors or, if thereafter 

requested by Holder, at the Company’s sole expense, by a third-party evaluator reasonably acceptable to Holder and having experience in the valuation of assets and businesses in the mining industry generally), and (iii) in the event that any
such acquisition is made by any subsidiary of the Company, each such subsidiary executes (i) a guaranty guaranteeing the full and punctual payment in full of all Indebtedness under the Note and any other Loan Documents, (ii) in the case of a stock
acquisition, a pledge in favor of Holder of the capital stock or equity acquired by such subsidiary, and (iii) a joinder to the Security Agreement, granting Holder a security interest in the assets acquired by such subsidiary as a result of any such
merger, consolidation or acquisition.

  course (including, without limitation, pursuant to any installment, output requirement,
  offtake or similar agreement with respect to the sale of future production in
  the ordinary course) to the extent that all net proceeds of any such sale, lease
  or disposition are applied to permanently reduce the Note in inverse order of
  maturity.

           1.6
  Compliance with Environmental Laws. The Company will not, and will not
  permit any of its subsidiaries to, (i) use any of the Property or any portion
  thereof for the handling, processing, storage, generation, manufacture, treatment,
  production, refining or disposal of hazardous substances, other than in compliance
  with environmental laws, except where the failure of such compliance would not
  be reasonably likely to have a material adverse effect upon the financial, business,
  legal condition or prospects of the Company and its subsidiaries, taken as a
  whole (a “Material Adverse Effect”), (ii) cause or permit to be located
  on any of the Property any underground tank, surface impoundment, lagoons, pits,
  sumps, or underground storage receptacle for hazardous substances in any manner
  that would violate any environmental law in any material respects or bring such

  generate any hazardous substances on any of the Property in any manner that
  would violate any environmental law or bring such Property in violation of any
  environmental law, (iv) conduct any activity at any of the Property or use any

  that would violate any environmental law or bring such Property in violation
  of any environmental law in any material respects, in each case except where
  such violation would not be reasonably likely to have a Material Adverse Effect.

           1.7
  Business Activities. Without the prior written consent of Holder, which
  consent may be given or denied at Holder’s sole discretion, the Company
  will not cease engaging in its business or engage directly or indirectly (whether
  through subsidiaries or otherwise) in any type of business other than the businesses
  presently or currently planned to be conducted by them and in related lines
  of businesses.

           1.8
  Transactions with Affiliates. Without the prior written consent of Holder,
  which 

consent may be given or denied at Holder’s sole discretion, other than the transactions disclosed in the documents referred to in Schedule I and settlement agreements to be entered into between the Company and Ronald A. Hirsch, Steven D.
Seymour and TMD Acquisition Corporation and other than in the Company’s ordinary course of business, the Company will not engage in any transaction with any affiliate (other than for services as employees, officers and directors), including any
contract, agreement or other arrangement providing for the furnishing of services to or by, providing for rental of real or personal property to or from, or otherwise requiring payments to or from any such affiliate or, to the knowledge of the
Company, any person in which any such affiliate has a substantial interest or is an officer, director, partner, member or trustee on terms more favorable to such Person than would have been obtainable on an arm’s-length basis in the ordinary
course of business.  Notwithstanding the provisions of this Section 1.8 to the contrary, the Company shall not, other than in connection with any transaction or agreement which is permitted hereunder, (A) enter into or consummate any
transaction or agreement pursuant to which it becomes a party to any mortgage, note, indenture or guarantee evidencing any Indebtedness of any of its affiliates or otherwise to become responsible or liable, as a guarantor, surety or otherwise,
pursuant to an agreement for any Indebtedness of any such affiliate, or (B) make any payment to any of its affiliates in excess of $10,000 without the prior written consent of Holder.

           1.9
  Conflicting Agreements. Without the prior written consent of Holder,
  which consent may be given or denied at Holder’s sole discretion, the Company
  will not enter into any amendment or other modification to any currently existing
  contractual obligation, which by its terms materially impairs the ability of
  the Company to (a) pay the principal of or interest on the Note, or (b) fully
  satisfy all of its obligations hereunder. 

           1.10
  Fiscal Year 2004 and Quarterly Financial Statements. Within thirty (30)

  a copy of the Company’s monthly operating reports and such other reports
  as Holder may reasonably request.

  Effect with respect to the Property or the Company’s ability to perform
  its obligations under the Note. 

           1.13
  Payment of Accrued Compensation. The Company will not, and will not permit
  any of its subsidiaries to, pay in cash any of the Indebtedness disclosed in
