                     AGREEMENT OF ASSIGNMENT AND ASSUMPTION

     THIS AGREEMENT OF ASSIGNMENT AND ASSUMPTION (the "Assignment Agreement") is
dated effective as of the 26th day of February, 2005, by and between Ronald A.
Hirsch, an individual residing in the county of Orange, State of California
("Hirsch") and Stephen D. Seymour, an individual residing in the county of
Baltimore, State of Maryland ("Seymour", and collectively with Hirsch, the
"Assignors"), on the one hand, and TMD Acquisition Corporation, a Tennessee
corporation (the "Assignee") on the other hand.

                                    RECITALS

     WHEREAS, since May 20, 2004, Nord Resources Corporation ("Nord") has been
pursuing an opportunity (the "Opportunity") to acquire certain assets from
ASARCO Incorporated, a New Jersey corporation ("ASARCO"), which assets comprise
the entire Tennessee Mines Division zinc business as conducted by ASARCO and
consisting of the Young, Immel and Coy mines, the Young Concentrator and the
Middle Tennessee exploration properties, including in all cases the operations,
impoundments, processing and other facilities incidental and ancillary to each
of the foregoing (collectively, the "TMD Assets");

     WHEREAS, as a result of the development efforts of Nord, Nord has been
selected by ASARCO as the primary candidate it will negotiate with for the
acquisition of the TMD Assets, and as to which Nord has received versions of a
draft Asset Purchase Agreement (the "Purchase Agreement") for negotiation and
execution;

     WHEREAS, Nord has entered into a bridge loan agreement with Regiment
Capital III, L.P., a Delaware limited partnership (the "Lender"), pursuant to
which Nord entered into, executed and delivered to Lender a Promissory Note, a
Security Agreement, a Pledge and Security Agreement, and certain other documents
(collectively, the "Loan Documents"), which Loan Documents contain certain
affirmative and negative covenants which with Nord must abide during the
pendency of the bridge loan, and which, among other things, will restrict Nord
from using its capital resources to make an investment in, or conduct any
business with respect to, the TMD Opportunity without its prior written consent
(and, as to which, the Lender has advised this Board of Directors of Nord that
it will not consent to Nord undertaking the TMD Opportunity at this time or
within the foreseeable future);

     WHEREAS, on October 14, 2004, the Assignors assumed from Nord all of Nord's
rights and interests in the TMD Opportunity, including without limitation under
the Purchase Agreement (collectively, the "TMD Rights"), to fund such further
development expenses as are necessary to complete the acquisition of and exploit
commercially the TMD Opportunity independent of Nord (the "Post-Development
Expenses"), and to "reserve" the place of Nord with respect to such TMD
Opportunity

                                        1

<PAGE>

until such time as the Lender may consent to its re-acquisition of the TMD
Rights from, and as further developed by, the Assignee;

     WHEREAS, on October 14, 2004, in consideration for the assignment of the
TMD Rights to the Assignors by Nord, the Assignors entered into an Agreement of
Option and Right of First Refusal with Nord, attached hereto as Exhibit A and
made an integral part hereof (the "Option Agreement"), and provided to Nord a
right of first refusal and option to acquire (the "TMD Option Rights") the TMD
Rights from the Assignors upon the payment to the Assignors of the
Post-Development Expenses plus such premium for taking the risks of development
of the TMD Opportunity as the parties may mutually agree (and as established as
fair and reasonable to Nord by an independent person with experience in the
valuation of business opportunities in the mining industry generally)
("Premium");

     WHEREAS, the Assignee has expressed its willingness to assume from the
Assignors all of their rights and interests in the TMD Rights, to fund the
Post-Development Expenses, and to "reserve" the place of Nord with respect to
such TMD Opportunity until such time as the Lender may consent to Nord's
re-acquisition of the TMD Rights from, and as further developed by, the
Assignee; and

     WHEREAS, in consideration for the assignment of the TMD Rights to the
Assignee as contemplated herein, the Assignee shall assume all of Assignors'
duties and obligations under the Option Agreement.

<PAGE>

                                      -14-

reasonable access to the Real Property, Assets and Business, provided that such
access shall be conducted by Buyer and its representatives in such a manner as
not to interfere unreasonably with the Business. Additionally, Seller shall
provide to Buyer in a timely manner all information as is reasonably requested
by Buyer in order for Buyer to provide documentation and information to Buyer's
investors or potential investors in the Business. Buyer shall notify Seller in
writing promptly upon its discovery of any information which, in its good faith
discretion, constitutes or would indicate a breach by Seller of any
representation, warranty, covenant or agreement of Seller hereunder. Should any
information require any change in any Schedule attached hereto if the Schedule
were dated the date of the occurrence or discovery of any such fact or
condition, Seller shall promptly deliver to Buyer a supplement to such Schedule
incorporating such change, which will be deemed to have amended such Schedule
for all purposes. Unless Buyer timely exercises a right to terminate this
Agreement pursuant to Section 10.3(c), Seller's supplement pursuant to this
Section 5.1 shall be deemed to amend this Agreement and any related Schedules
and to have cured any misrepresentations or breach of representation or warranty
that otherwise might have existed by reason of such fact or condition. Any
information provided pursuant to this Section 5.1 shall be subject to the
Confidentiality Agreement.

unreasonably withhold its consent to providing such documents. The Seller shall
however be entitled to withhold its consent to a request for copies of, or
access to documents where:

          (i) the information is confidential or commercially sensitive to
     Seller or an Affiliate of Seller; or

          (ii) the information is confidential to any third party;

Provided, however, that such information will not be withheld if it is required
to be disclosed by Buyer in connection with Buyer's compliance with any
securities or other Law and such information pertains to or was used by the
Business. Buyer shall reimburse Seller for any costs reasonably incurred by
Seller in complying with a request for copies of or access to documents under
this clause.

     (c) Buyer will retain all books, records and other documents pertaining to
the Business in existence at the Effective Time and transferred to Buyer as part
of the Assets and will make the same available after the Effective Time for
inspection and copying by Seller at such Person's expense during the normal
business hours of Buyer upon reasonable request and upon reasonable notice. For
a period of seven (7) years following the Closing Date, no such books, records
or documents shall be destroyed by Buyer without first advising Seller in

Seller and any Affiliate of Seller, and their respective representatives, all
information deemed necessary or desirable by Seller in preparing their
respective financial statements or tax returns. Seller shall provide to Buyer at

by counsel of its choosing, provided that such counsel is reasonably
satisfactory to the Indemnified Party; provided, however, that the Indemnified
Party shall have the right to engage its own counsel, at its own expense, to
participate in such defense. Such counsel shall be afforded access to all
information pertinent to the suit or proceeding in question. If, in the
reasonable opinion of counsel to the Indemnified Party, there are defenses
available to the Indemnified Party which are different from or additional to
those available to the Indemnifying Party or which give rise to a material
conflict between the defense of the Indemnified Party and of the Indemnifying
Party, then upon notice to the Indemnifying Party, the Indemnified Party may
elect to engage separate counsel to conduct its defense, at the expense of the
Indemnifying Party, and the Indemnifying Party shall not have the right to
direct or conduct such defense. The Indemnifying Party shall not settle or
otherwise compromise any such suit or proceeding without the prior consent of
the Indemnified Party, which consent shall not be unreasonably withheld, if the
effect of such settlement or compromise would be to impose material liability on
the Indemnified Party.

believes that it has or will suffer any Losses for which an Indemnifying Party
is obligated to indemnify it hereunder, it shall promptly notify such

the Indemnified Party believes that the Indemnifying Party is or will be
obligated to indemnify, the amount, if liquidated, to be indemnified, and the
basis on which the Indemnified Party has calculated such amount; if not yet
liquidated, the notice shall so state.

the result of a breach of this Agreement by the Party seeking to terminate this
Agreement or the amendment of any Schedule pursuant to Section 5.1(a) of this
Agreement which amendment, materially and adversely affects the value of the
transaction contemplated hereby.;

     (c) by Buyer after receipt by Buyer of a supplement delivered by Seller

be waived at any time prior to or at the Closing hereunder by the Party entitled

waiver of any other breach of such provision, nor in any way to

affect the validity of this Agreement or any part hereof or the right of such
Party thereafter to enforce each and every such provision. No waiver of any
breach of or non-compliance with this Agreement shall be held to be a waiver of
any other or subsequent breach or non-compliance.

counterparts, each of which shall be deemed an original but all of which
together will constitute one and the same instrument.

proceeding for itself and in respect to its property, generally and
unconditionally, to the jurisdiction of the aforesaid courts. Each of the
Parties hereto hereby irrevocably waives, and agrees not to assert, by way of
motion, as a defense, counterclaim, or otherwise, in any Action or proceeding
with respect to this Agreement, (a) any claim that it is not personally subject
to the jurisdiction of the above named court for any reason other than the
failure to serve process in accordance with this Section 10.11, (b) that it or
its property is exempt or immune from jurisdiction of any such court or from any
legal process commenced in such courts (whether through judgment or otherwise),
and (c) to the fullest extent permitted by applicable Law that (i) the Action or
proceeding in any such court is brought in an inconvenient forum, (ii) the venue
of such Action or proceeding is improper and (iii) this Agreement, or the
subject matter hereof, may not be enforced in or by such courts. Each Party

limitation, the reasonable expenses of its attorneys) in bringing or defending
against such action.

by all parties that no objection to the form of the action or the relief prayed
for in any proceeding for specific performance of this Agreement shall be raised

remedy granted hereunder or by law, equity or statute or otherwise. No course of
dealing and no delay on the part of any Party in exercising any right, power or
remedy shall operate as a waiver thereof or otherwise prejudice its rights,
