                  2.       COMPENSATION.

                  In full compensation for the services to be rendered by the

                           (a) a basic annual salary of One Hundred Ten Thousand
($110,000) Dollars for each employment year of the Employment Term payable in
installments not less frequently than monthly, and increased as the Board of
Directors may, from time to time, determine in its discretion; plus

                           (b) for each fiscal year (November 1 to October 31)
of the Company ending during the employment of the Employee, a year end bonus of
$25,000, provided that the Employee is in the employ of the Company at the close
of such year and the Company shall not have incurred a net loss for such fiscal
year determined in accordance with generally accepted accounting principles

reported in writing, as to whether the Company had a net loss within the meaning
of this clause (b) for such year; plus

                           (c) such additional amounts, if any, as the Board of
Directors of the Company may determine from time to time in its discretion.

consent.
                  4.       TRAVEL; EXPENSES.

                  The Employee shall engage in such travel as may reasonably be
required in connection with the performance of his duties, in accordance with
prior practice. Employee recognizes that the position Vice President - Sales and
Marketing requires substantial travel.

                  All reasonable travel and other expenses incurred by the
Employee (in accordance with the policies of the Company established from time
to time) in carrying out his duties hereunder will be reimbursed by the Company
on presentation to it of expense accounts and appropriate documentation in
accordance with the customary procedures of the Company for reimbursement of
executive expenses. The Employee shall be entitled to a travel expense advance
in the discretion of the Company when anticipated travel warrants such advance.

                  5.       EARLY TERMINATION OF EMPLOYMENT TERM ON DISABILITY OR
                           DEATH.

                           (a) If during the Employment Term, the Employee fails
because of illness or other incapacity (including incapacity because of
substance abuse) to render to the Company the services required of him hereunder
for a period of two months (during which the Company shall continue the
Employee's compensation at the rates herein provided), the Company may, in its
discretion, give one month notice of termination of the Employment Term (during
which the Employee's compensation shall likewise be continued), and if the
Employee shall not resume full performance of his duties within such one month
period, the Employment

                                       3
<PAGE>

Term shall terminate at the expiration thereof, provided that any such
termination shall not affect the right of the Employee (or his estate) to
continue to receive benefits under any disability insurance plan covering the
Employee which is in effect at the date of termination, and further provided
that if any such termination shall be during a fiscal year and the Company shall
not have a net loss determined as provided in paragraph 2(b) for such fiscal
year, the Employee shall be entitled to a pro-rata portion of the bonus for such
year based on the number of full months worked by him in such year.

                           (b) The Employment Term shall end upon the death of
the Employee, provided that if the Employee shall die during a fiscal year, and
the Company shall not have a net loss, determined as provided in paragraph 2(b),
for such fiscal year, the Employee shall be entitled to a pro-rata portion of
the bonus for such year, based on the number of full months worked by him during
such year.
                  6.       VACATION.

                  During the Employment Term, the Employee shall be entitled to
vacation periods not exceeding four weeks in each year, to be taken at such time
or times as shall be mutually convenient to the Company and the Employee (but
not more than two weeks consecutively). Unused vacation shall not accumulate
from year to year.

                  7.       CONFIDENTIALITY; COMPETITION.

                           (a) For the purposes hereof, all confidential
information about the business and affairs of the Company (including, without
limitation, business plans, financial and marketing information and information
about its secrets and machinery, designs, plans, patterns and specifications,
formulae, processes, inventions and discoveries, and names of suppliers and

                                       4
<PAGE>

customers and nature of dealings with them, sales data and marketing plans)
constitute "Company Confidential Information." Since August 10, 1998, the
Employee has been an employee of the Company in a senior marketing position. He
acknowledges that he has in the past had, and will continue to have, access to
and knowledge of Company Confidential Information, and that improper use or
revelation of same by the Employee during or after the termination of his
employment by the Company could cause serious injury to the business of the
Company. Accordingly, the Employee agrees that he will forever keep secret and
inviolate all Company Confidential Information which shall have come or shall
hereafter come into his possession, and that he will not use the same for his
own private benefit, or directly or indirectly for the benefit of others, and
that he will not disclose such Company Confidential Information to any other
person other than in pursuance of Company business.

                           (b) During the Employment Term and for a period of
two years thereafter, the Employee will not (whether as an officer, director,
partner, proprietor, investor, associate, employee, consultant, adviser, public
relations or advertising representative or otherwise), directly or indirectly,
be engaged in any aspect of the business of producing and marketing pure
magnesium and/or magnesium alloy within the entire world (which the parties
acknowledge is the Company's trading area). For purposes of the preceding
sentence, the Employee shall be deemed to be engaged in any business which any
person for whom he shall perform services is engaged. Nothing herein contained
shall be deemed to prohibit the Employee from owning, as a passive investment, a
security of any issuer which is not a supplier, vendor; customer or competitor
of the Company and whose securities are publicly traded.

                  Notwithstanding the foregoing,

                                    (i)      If the Company terminates this
                                             Agreement or declines to extend
                                             this Agreement at the end of the
                                             Employment Term, other than for
                                             cause, the non-competition period
                                             shall be one year, rather than two
                                             years;

                                    (ii)     If the assets of the Company are
                                             sold substantially as an entirety,
                                             or its stock is sold, in either
                                             case, to a purchaser not affiliated
                                             with The Renco Group, Inc. and if
                                             Employee is not offered employment
                                             by the new owner for reasons, other
                                             than for cause, the non-competition
                                             period shall be one year, rather
                                             than two years; and

                                    (iii)    If the stock or assets of the
                                             Company are sold substantially as
                                             an entirety to an entity controlled
                                             by Dow Chemical Company or by
                                             Timminco, there shall be no
                                             non-competition period.

                           (c) Within the terms of this Agreement, it is
intended to limit disclosure and competition by the Employee to the maximum
extent permitted by law. If it shall be finally determined by any court of
competent jurisdiction ruling on this Agreement that the scope or duration of
any limitation contained in this paragraph 7 is too extensive to be legally
enforceable, then the parties hereby agree that the scope and duration (not
greater than that provided for herein) of such limitation shall be the maximum
scope and duration which shall be legally enforceable and the Employee hereby
consents to the enforcement of such limitation as so modified.

                           (d) The Employee acknowledges that any violation by
him of the provisions of this paragraph 7 could cause serious and irreparable
damages to the Company. He further acknowledges that it might not be possible to
measure such-damages in money. Accordingly, the Employee further acknowledges
that, in the event of a breach or threatened breach by him of the provisions of
this paragraph 7, the Company may seek, in addition to any

                                       6
<PAGE>

other rights or remedies, including money damages, an injunction or restraining
order, restraining the Employee from doing or continuing to do or perform any
acts constituting such breach or threatened breach.

                  8.       EMPLOYEE'S INVENTIONS.

                  The Employee agrees to assign and transfer to the Company, its
successors and assigns, his entire right, title and interest in and to any or
all inventions, designs, discoveries and improvements which he may make, either
solely or jointly with others, during the Employment Term hereunder and for a
period of one (1) year thereafter, which relate in any way to the business or
products of the Company, together with all rights to letters patent which may be
granted thereon. Immediately upon making any inventions, designs, discoveries or
improvements, the Employee shall notify the Company and, without further
compensation, shall execute and deliver to the Company such documents as may be
necessary to prepare or prosecute applications for patents upon such inventions,
designs, discoveries and improvements, and shall assign and transfer to the
Company his entire right, title and interest therein. The Company shall pay all
expenses involved in carrying out the provisions of this paragraph 8.

                  9.       BENEFITS.

                  The Company agrees to continue to provide to the Employee
during the Employment Term the same medical, hospitalization, disability
insurance benefits and all other benefits as were provided to him immediately
prior to the execution of this Agreement.

                  10.      EMPLOYEE'S REPRESENTATION.

                  Employee hereby represents to the Company that he has full
right and power to enter into this Agreement and carry out his duties hereunder,
and that same will not constitute a

                                       7
<PAGE>

breach of or default under any employment, confidentiality, non-competition or
other agreement by which he may be bound.

                  11.      DEFAULT BY EMPLOYEE.

                  If the Employee shall:

                           (i)      commit an act of dishonesty against the
                                    Company or fraud upon the Company; or

                           (ii)     breach his obligations under this Agreement
                                    and fail to cure such breach within five (5)
                                    days after written notice thereof; or

                           (iii)    be convicted of a crime involving moral
                                    turpitude; or

                           (iv)     fail or neglect diligently to perform his
                                    duties hereunder and continue in his failure
                                    after written notice;

then, and in any such case, the Company may terminate the employment of the
Employee hereunder and, in the event of any such termination, the Employee shall
no longer have any right to any and all benefits (including future salary
payments) which would otherwise have accrued after such termination.

                  12.      AUTOMATIC RENEWAL.

                  This Agreement shall automatically renew and be extended from
year to year upon the expiration of the Employment Term (as extended if
extended) unless terminated by either party by written notice given to the other
at least six months prior to October 31 2001, or prior to any subsequent October
31. If any such notice shall be given, this Agreement shall terminate on October
31, 2001, or the next succeeding October 31, as the case may be.

         Addendum to the "Amendment to Employment Agreement and Consulting
         Agreement"

         1.       The company has grossed up the employee's consulting fee to
                  include the costs of medical, vision, dental, and life
                  insurance benefits equivalent to regular employees throughout
                  the term of the consulting agreement. No further costs will be
                  paid by the company, but Kaplan will be able to exercise all
                  his normal rights under the postretirement medical plan and
                  life insurance plan and can exercise the Cobra option at his
                  own expense.

         2.       The employee will establish an office in his home in Las
                  Vegas, Nevada, and the Company will pay for those necessary
                  business expenses associated with that office, such as a fax
                  machine, extra telephone lines for fax and computer,
                  miscellaneous office supplies, equipment repair, etc.

         3.       The employee will be able to attend annual meetings of the IMA
                  and TMS at Company expense for the duration of the consulting
                  period. For the purpose of time spent, these meeting will be
                  assumed to take a maximum of 40 hours, regardless of the
                  location of the meetings.

         4.       The employee will travel as requested by the President or Vice
                  President of Sales and Marketing under the standard employee
                  expense and entertainment policy. This includes all travel
                  from the employee's home base of Las Vegas, Nevada. It is
                  anticipated that the employee will come to Salt Lake City at
                  Company request about 2 times per month for 3-4 days per time.
                  Expenses to be paid by the Company during these trips will be
                  airfare, car rental, hotel (Marriott or Little America), and
                  meals and miscellaneous expenses as per Magcorp expense
                  policy.

         5.       The employee will submit monthly time records documenting the
                  work hours spent under the base 80 hours of this agreement.
                  Additional hours beyond 80 in a month must be approved in
                  advance by the President of Magcorp or his designate. Such
                  hours will be reimbursed at a rate of $75/hour. Timekeeping
                  will be done to the nearest half-hour.

         6.       I intend to form a subchapter s corporation to receive the
                  payments and assume that this will cause no problems.
