                              EMPLOYMENT AGREEMENT


                EMPLOYMENT AGREEMENT dated as of November 2, 2000 (the
"Agreement") by and between Wilshire Technologies, Inc., a California
corporation (the "Company") and Derek Warneke, an individual residing at San
Diego, California ("Executive").

                The Company and Executive desire to set forth the terms and
conditions on which (i) the Company shall employ Executive as Vice President of
Operations and Technology (ii) Executive shall render services to the Company,
and (iii) the Company shall compensate Executive for such services.

                NOW, THEREFORE, in consideration of the premises and of the

                The Company hereby employs Executive and Executive hereby
accepts such employment to perform executive services as hereinafter provided
for the period from November 20, 2000 through November 19, 2001. Commencing
November 20, 2001, the period of employment shall be automatically extended from

extend the employment. The original one-year period of this Agreement and any
extensions thereof are hereinafter referred to as the "Term".

        2. Duties and Responsibilities.

                2.1 During the Term Executive shall devote his full attention
and expend his best efforts, energies, and skills, on a full-time basis, to the
business of the Company and any corporation controlled by the Company (each a
"Subsidiary"). For purposes of this Agreement, the term the "Company" shall mean
the Company and all Subsidiaries.

                2.2 During the Term Executive shall serve as the Vice President

responsibilities hereunder, Executive shall be subject to all of the Company's
policies, rules and regulations applicable to its executives of comparable

President and Chief Executive Officer of the Company (the "CEO") and shall be
subject to the direction and control of the CEO.

                2.3 Executive's services shall be rendered principally in or
from an office located in the Carlsbad, California, area. Nevertheless,
Executive agrees to make such trips out of the area, for limited periods, as are
reasonably incident to the performance of his duties.

                2.4 Without first obtaining the written permission of the CEO in
each instance, Executive will not authorize or permit the Company to engage the
services of, or engage in any business activity with, or provide any financial
or other benefit to, any affiliate of Executive. The phrase "affiliate of
Executive" as used in this Section shall mean and include Executive's family by
blood or marriage (including, without limitation, parents, spouse, siblings,
children and in-laws), and any business or business entity which is directly or
indirectly owned or controlled by Executive or any member of Executive's family
or in which Executive or any member of Executive's family has any direct or
indirect financial interest whatsoever.

                2.5 In order to induce the Company to enter into this Agreement,
Executive represents and warrants to the Company that (a) Executive is not a
party or subject to any employment agreement or arrangement with any other
person, firm, company, corporation or other business entity, (b) Executive is
subject to no restraint, limitation or restriction by virtue of any agreement or
arrangement, or by virtue of any law or otherwise which would impair Executive's
right or ability to remain in the employ of the Company, or to perform fully his
duties and obligations pursuant to this Agreement, and (c) to the best of
Executive's knowledge, no material litigation is pending or threatened against
any business or business entity owned or controlled or formerly owned or
controlled by Executive.

        3. Compensation.

                3.1 During the Term the Company shall pay Executive a salary at
an annual rate of $125,000, subject to review after one year, and an automobile
allowance of $7,200 per year, payable in installments in accordance with the
Company's regular practice, but not less often than monthly.

                3.2 The Company hereby grants Executive a ten-year Non-Qualified
Stock Option under the Company's 1993 Stock Option Plan to purchase 100,000
shares of the common stock of the Company at the option exercise price set by

2001, vests on May 27, 2002 as to an additional 33,333 shares, vests on May 27,

                3.3 The Company will grant Execute two additional Stock option
grants on 50,000 common shares each under the Company's 1993 Stock option Plan,
priced at the average of the bid and ask quoted on the day of grant, after six
months of employment and upon Executive's completion of one year of employment,
respectively. These options will be granted upon approval by the President and
CEO based upon satisfactory progress toward completion of Executive's annual MBO
goals.

                3.4 Executive shall receive a bonus in accordance with the terms
of the Bonus Plan attached to this Agreement as Attachment B and incorporated
herein by this reference.

                3.5 Executive shall be entitled to reasonable periods of paid
sick leave, three weeks paid vacation per year and holidays in accordance with
the Company's regular policy.

                3.6 Executive is authorized to incur reasonable expenses in the
performance of his duties hereunder, including, but not limited to, Mexican
insurance for his personal vehicle used to travel to Mexico, and expenses of a
cell phone used for Company business. The Company shall reimburse Executive for
such expenses upon the presentation by Executive, not less frequently than
monthly, of signed, itemized accounts of such expenditures and vouchers, all in
accordance with the Company's procedures and policies as adopted and in effect
from time to time and applicable to its executives of comparable status.

                3.5 The Company shall provide Executive, at Company's expense,
participation in group medical, dental, accident, disability and life insurance
plans of the Company and other standard benefits as may be provided by the
Company from time to time to its executives of comparable status, subject to,
and to the extent that, Executive is eligible under such benefit plans in
accordance with their respective terms.

                3.6 If the Company requires the Employee to work in Mexico more
than 180 days in a calendar year and the Employee therefore is subject to
Mexican non-resident income taxes, and if such Mexican non-resident income taxes
plus the U.S. federal and California state income taxes the Employee pays exceed
the amount of combined U.S. federal and California state income taxes that the
Employee would have paid on a proforma basis if he had worked in the U.S. for
the full year, then the Company will pay to the Employee such excess, including
an amount for additional income taxes due on the payment, with the intention of
making the Employee whole.

        4. Termination.

                4.1 The Company may terminate Executive's employment under this
Agreement at any time for Cause. "Cause" shall exist for such termination if

reasonable judgment of the CEO, engaged in serious misconduct, which misconduct

CEO to Executive regarding such misconduct, (iv) refused to follow any lawful

Company further agrees to provide Executive, at Company's expense, group medical

        5. Restrictive Covenants.

                5.1 Executive acknowledges that (i) he has a major
responsibility for the administration, development and growth of the Company's
business, (ii) his work for the Company will bring him into close contact with
confidential information of the Company and its customers, and (iii) the
agreements and covenants contained in this Section 5 are essential to protect
the business interests of the Company and that the



                                       4
<PAGE>   5

Company will not enter into this Agreement but for such agreements and
covenants. Accordingly, Executive covenants and agrees as follows:

                        5.1.a Except as otherwise provided for in this
Agreement, during the Term Executive shall not, directly or indirectly, within
any state, province or other political subdivision of the United States or any
other country in which the Company is conducting business, compete with respect
to any services or products of the Company which are either offered or are being
developed by the Company (the "Company's Business"), or, without limiting the
generality of the foregoing, be or become, or agree to be or become, interested
in or associated with, in any capacity (whether as partner, shareholder, owner,
officer, director, employee, principal, agent, creditor, trustee, consultant,
co-venturer or otherwise), any individual, corporation, firm, association,
partnership, joint venture or other business entity, which competes with the
Company's Business; provided, however, that Executive may own, solely as an
investment, not more than one (1%) percent of any class of securities of any
publicly owned corporation.

                        5.1.b During, and for one year after, the Term,
Executive shall not, directly or indirectly, (i) induce or attempt to influence
any employee of the Company to leave its employ, (ii) aid or agree to aid any
competitor, customer or suppliers of the Company in any attempt to hire any
person who shall have been employed by the Company within the one year period
preceding such requested aid, or (iii) induce or attempt to influence any person
or business entity who was a customer or supplier of the Company during any
portion of said period to transact business with a competitor of the Company.

                        5.1.c During the Term and thereafter, Executive shall
not disclose to anyone any information about the affairs of the Company,
including, without limitation, trade secrets, trade "know-how", inventions,
customer lists, business plans, operational methods, pricing policies, marketing
plans, sales plans, identity of suppliers or customers, sales, profits or other
financial information, which is confidential to the Company or is not generally
known in the relevant trade, nor shall Executive make use of any such
information for his own benefit.

                5.2 Executive acknowledges and agrees that in the event of a
violation or threatened violation of any of the provisions of Section 5.1 (the
"Restrictive Covenants") the Company shall have no adequate remedy at law and
shall therefore be entitled to enforce each such provision by temporary or
permanent injunctive or mandatory relief obtained in any court of competent
jurisdiction without the necessity of proving damages or posting any bond or
other security, and without prejudice to any other rights and remedies which may
be available at law or in equity.

                5.3 If any of the Restrictive Covenants, or any part thereof, is
held to be invalid or unenforceable, the same shall not affect the remainder of
the covenant or covenants, which shall be given full effect, without regard to
the invalid or unenforceable portions. Without limiting the generality of the
foregoing, if any of the Restrictive



                                       5
<PAGE>   6

Covenants, or any part thereof, is held to be unenforceable because of the
duration of such provision or the area covered thereby, the parties hereto agree
that the court making such determination shall have the power to reduce the
duration and/or scope and/or area of such provision and, in its reduced form,
such provision shall then be enforceable.

                5.4 The parties hereto intend to and hereby confer jurisdiction
to enforce the Restrictive Covenants upon the courts of any jurisdiction within
the geographical scope of such Restrictive Covenants. In the event that the
courts of any one or more of such jurisdictions shall hold such Restrictive
Covenants wholly unenforceable by reason of the breadth of such scope or
otherwise, it is the intention of the parties hereto that such determination not
bar or in any way affect the Company's right to the relief provided above in the
courts of any other jurisdictions, within the geographical scope of such
Restrictive Covenants, as to breaches of such covenants in such other respective
jurisdictions, the above covenants as they relate to each jurisdiction being,
for this purpose, severable into diverse and independent covenants.

        6. Insurance.

                6.1 The Company may, from time to time, apply for and take out,
in its own name and at its own expense, life, health, accident, disability or
other insurance upon Executive in any sum or sums that it may deem necessary to
protect its interests, and Executive agrees to aid and cooperate in all
reasonable respects with the Company in procuring any and all such insurance,
including without limitation, submitting to the usual and customary medical
examinations, and by filling out, executing and delivering such applications and
other instruments in writing as may be reasonably required by an insurance
company or companies to which an application or applications for such insurance
may be made by or for the Company. In order to induce the Company to enter into
this Agreement, Executive represents and warrants to the Company that to the
best of his knowledge Executive is insurable at standard (non-rated) premiums.

        7. Miscellaneous.

                7.1 This Agreement is a personal contract, and the rights and
interests of Executive hereunder may not be sold, transferred, assigned, pledged
or hypothecated except as otherwise expressly permitted by the provisions of
this Agreement. Executive shall not under any circumstances have any option or
right to require payment hereunder otherwise than in accordance with the terms
hereof. Except as otherwise expressly provided herein, Executive shall not have
any power of anticipation, alienation or assignment of payments contemplated
hereunder, and all rights and benefits of Executive shall be for the sole
personal benefit of Executive, and no other person shall acquire any right,
title or interest hereunder by reason of any sale, assignment, transfer, claim
or judgment or bankruptcy proceedings against Executive, provided, however, that
in the event of Executive's death, Executive's estate, legal representatives or
beneficiaries (as the case may be) shall have the right to receive all of the
benefits that accrued to Executive pursuant to, and in accordance with, the
terms of this Agreement.
