limitation, the Arizona Department of Health Services, Arizona Department of

testing and all remedial, removal, and other actions necessary to clean up and
remove all Hazardous Substances in, from or affecting the Johnson Camp Mine;

     (a) In compliance with all applicable Environmental Laws;

     (b) In accordance with the orders and directives of all governmental

5. If Lender shall ever have good reason to believe that there are Hazardous
Substances (other than those disclosed in writing to Lender) affecting any of
the Johnson Camp Mine, Lender (by their respective officers, employees, and
agents) at any time and from time to time may contract for the services of
persons (the "SITE REVIEWERS") to perform environmental site assessments ("SITE
ASSESSMENTS") on the Johnson Camp Mine for the purpose of determining whether
there exists on the Johnson Camp Mine any environmental condition that could
result in any liability, cost, or expense to the owner, occupier, or operator of
such Johnson Camp Mine arising under any Environmental Laws. The Site
Assessments may be performed at any time or times, upon reasonable notice, and
under reasonable conditions established by Nord that do not impede the
performance of the Site Assessments and do not unreasonably interfere with any
of Nord's activities or operations at the Johnson Camp Mine. The Site Reviewers
are hereby authorized to enter upon the Johnson Camp Mine for such purposes. The
Site Reviewers are further authorized to perform both above and below the ground
testing for environmental damage or the presence of Hazardous Substances on the
Johnson Camp Mine and such other tests on the Johnson Camp Mine as may be
necessary to conduct the Site Assessments in the reasonable opinion of the Site
Reviewers. Nord will supply to the Site Reviewers such historical and
operational information regarding the Johnson Camp Mine as may be reasonably
requested by the Site Reviewers to facilitate the Site Assessments and will make
available for meetings with the Site Reviewers appropriate personnel having
knowledge of such matters. On request, Lender shall make the results of such
Site Assessments fully available to Nord, which (prior to an Event of Default


                                        3

<PAGE>

under the Loan Documents) may, at their election, participate under reasonable
procedures in the direction of such Site Assessments and the description of
tasks of the Site Reviewers. The cost of performing such Site Assessments shall
be paid by Lender. Lender agrees to keep all data and information pertaining to
the Site Assessments, and the Site Assessments themselves, confidential, and not
to disclose any such data or information to any third party (other than the
consultants preparing the Site Assessments; unless such disclosure is required
by applicable law or court order).

6. Lender shall have the right, but not the obligation, without in any way
limiting Lender's other rights and remedies under the Loan Documents, to enter
onto the Johnson Camp Mine or to take such other actions as it deems reasonably
necessary or advisable in good faith, to clean up, remove, resolve, or minimize
the impact of, or otherwise deal with, any Hazardous Substances on or affecting
the Johnson Camp Mine following receipt of any notice from any person or entity
asserting the existence of any Hazardous Substances pertaining to the Johnson
Camp Mine or any part thereof that, if true could result in an order, notice,
suit, imposition of a lien on the Johnson Camp Mine, or other action and/or
that, in Lender's reasonable and good faith opinion, could jeopardize Lender's
security under the Loan Documents. All reasonable costs and expenses paid or
incurred by Lender in the exercise of any such rights shall be paid by Nord, and
all such reasonable costs and expenses paid or incurred by Lender shall be
secured by the Loan Documents and shall be payable by Nord upon demand. All such
actions taken by Lender pursuant to this Paragraph 7 shall be in a manner so as
not to unreasonably interfere with any of Nord's activities or operations at the
Johnson Camp Mine, and shall be taken in accordance with Nord's reasonable
safety rules and regulations and any such rules and regulations imposed by any
governmental agency.

7. Lender shall have the right at any time to appear in and to participate in,
as a party if it so elects, and be represented by counsel of its own choice in,
any action or proceeding initiated in connection with any Environmental Law that
affects the Johnson Camp Mine.

8. Nord shall indemnify and hold harmless Lender, any successor to Lender, any
purchaser of the Johnson Camp Mine upon foreclosure of Lender's interest in the
Johnson Camp Mine, and all directors, officers, employees and agents of all of
the foregoing, from and against all claims, costs, expenses, actions, suits,
proceedings, losses, damages and liabilities of any kind whatsoever, including
but not limited to attorneys' fees and expenses, directly or indirectly arising
out of or attributable to (i) the use, generation, manufacture, production,
storage, Release, threatened Release, or presence of a Hazardous Substance on,
under or about the Johnson Camp Mine occurring from and after the closing of the
sale of the Johnson Camp Mine to Nord and not substantially arising out of or
substantially related to any material action or omission to act by Lender; (ii)
any violation or claim of violation of any Environmental Law with respect to the
Johnson Camp Mine, and not substantially arising out of or substantially related
to any material action or omission to act by Lender; or (iii) any material
breach of any of the warranties, representations and covenants contained herein.
Lender shall give written notice to Nord promptly of any claim, suit, action,
the commencement of any proceeding


                                        4

<PAGE>

or demand of which Lender has received written notice from a third party and as
to which Lender believes it may be entitled to indemnification hereunder.

9. This Agreement shall be binding upon Nord and its successors and assigns and
shall inure to the benefit of Lender, their respective successors and assigns.
The indemnity contained herein shall continue in full force and effect and shall
survive the payment and performance of the Note, the release of any lien or
encumbrance securing the Note, any foreclosure (or action in lieu of
foreclosure) of any lien or encumbrance securing the Note, the exercise by
Lender of any other remedy under any documents securing the Note, and any suit,
proceeding or judgment against Nord by Lender hereon.

10. If any material warranty, representation or statement contained herein shall
be or shall prove to have been false when made or if Nord shall fail or neglect
to perform or observe any of the terms, provisions or covenants contained
herein, the same shall constitute an Event of Default under the Note and under
all documents and instruments executed and delivered in connection therewith
that shall entitle Lender to pursue any and all remedies provided for such
default.

11. Any notice required or permitted in connection herewith shall be given in
the manner provided in the Note or other documents executed and delivered in
connection with the Note.

12. Nord acknowledges that Lender has and will rely upon the representations,
warranties and agreements herein set forth in closing and funding (or modifying
as the case may be) the Note and that the execution and delivery of this
Agreement is an essential condition but for which Lender would not have agreed
to loan Nord the funds as set forth in the Note.

13. Nord waives any right or claim of right to cause a marshaling of the assets
of Nord or to cause Lender to proceed against any of the security for the Note
before proceeding under this Agreement against Nord; Nord agrees that any
payments required to be made hereunder shall become due on demand; Nord
expressly waives and relinquishes all rights and remedies accorded by applicable
law to Nord or guarantors (including, without limitation, A.R.S. Sections
12-1641, et seq., and 44-142, and Rule 17f of the Arizona Revised Statutes Rules
of Civil Procedure), except any rights of subrogation that Nord may have,
provided that the indemnity provided for hereunder shall neither be contingent
upon the existence of any such rights of subrogation nor subject to any claims
or defenses whatsoever that may be asserted in connection with the enforcement
or attempted enforcement of such subrogation rights, including, without
limitation, any claim that such subrogation rights were abrogated by any acts or
omissions of Lender.

14. This Agreement shall be governed by and construed according to the laws of
the State of Arizona, without giving effect to conflict of laws principles.
