PETREX Common Stock is to be issued in a name other than that in which the
Certificate surrendered in exchange therefore is registered, it will be a
condition of the issuance thereof that the Certificate so surrendered will be

holder or former holder of Company Common Stock such amounts as may be required
to be deducted or withheld therefrom under the Code or under any provision of
state, local, or foreign tax law or under any other applicable legal
requirement. To the extent such amounts are so deducted or withheld, such
amounts shall be treated for all purposes under this Agreement as having been
paid to the person to whom such amounts would otherwise have been paid.

         5.4      NO SOLICITATION.

         (i) From and after the date of this Agreement until the Effective Time

of Directors of Company from (m) complying with Rule 14d-9 or 14e-2(a)
promulgated under the Exchange Act with regard to a tender or exchange offer not
made after a violation of this Section 5.4(a) or (n) at any time prior to the
date of the Company Shareholders' Meeting, in response to a bona fide written
Acquisition Proposal received without the prior occurrence of a breach of this
Section 5.4(a) that Company's Board of Directors reasonably concludes
constitutes a Superior Proposal (as defined below), engaging in discussions or
participating in negotiations with and furnishing information to the party
making such Acquisition Proposal to the extent (1) the Board of Directors of
Company determines in good faith after consultation with its outside legal
counsel that its fiduciary obligations under applicable law require it to do so,
(2) (x) at least two business days prior to furnishing any such nonpublic
information to, or entering into discussions or negotiations with, such party,
Company gives PETREX written notice of Company's intention to furnish nonpublic
information to, or enter into discussions or negotiations with, such party and
(y) Company receives from such party an executed confidentiality agreement
containing customary limitations on the use and disclosure of all nonpublic
written and oral information furnished to such party by or on behalf of Company,
and (3) contemporaneously with furnishing any such nonpublic information to such
party, Company furnishes such nonpublic information to PETREX (to the extent
such nonpublic information has not been previously furnished by Company to
PETREX). Company and its subsidiaries will immediately cease any and all
existing activities, discussions, or negotiations with any parties conducted
heretofore with respect to any Acquisition Proposal. Without limiting the
foregoing, it is understood that any violation of the restrictions set forth in
this Section 5.4(a) by any officer, director, affiliate or employee of Company
or any of its subsidiaries or any investment banker, attorney or other advisor
or representative of Company or any of its subsidiaries shall be deemed to be a

                                       25


breach of this Section 5.4(a) by Company. (ii) For purposes of this Agreement,

an offer, inquiry or proposal by PETREX) relating to any Acquisition
Transaction. For the purposes of this Agreement; (B) "ACQUISITION TRANSACTION"
shall mean any transaction or series of related transactions other than the
transactions contemplated by this Agreement involving: (X) any acquisition or
purchase from Company by any person or "group" (as defined under Section 13(d)
of the Exchange Act and the rules and regulations thereunder) of more than a 15%
interest in the total outstanding voting securities of Company or any of its
subsidiaries or any tender offer or exchange offer that if consummated would
result in any person or "group" (as defined under Section 13(d) of the Exchange
Act and the rules and regulations thereunder) beneficially owning 15% or more of
the total outstanding voting securities of Company or any of its subsidiaries or
any merger, consolidation, business combination or similar transaction involving
Company pursuant to which the shareholders of Company immediately preceding such
transaction hold less than 85% of the equity interests in the surviving or
resulting entity of such transaction; (Y) any sale, lease (other than in the
ordinary course of business), exchange, transfer, license (other than in the
ordinary course of business), acquisition or disposition of more than 15% of the
assets of Company; or (Z) any liquidation, dissolution, recapitalization or
other significant corporate reorganization of the Company; and (C) "SUPERIOR
PROPOSAL" shall mean an Acquisition Proposal with respect to which (x) if any
cash consideration is involved, shall not be subject to any financing
contingency or with respect to which Company's Board of Directors shall have
reasonably determined (based upon the advice of Company's financial advisors)
that the acquiring party is capable of consummating the proposed Acquisition
Transaction on the terms proposed, and (y) Company's Board of Directors shall
have reasonably determined that the proposed Acquisition Transaction provides
greater value to the shareholders of Company than the Merger (based upon a
written opinion of Company's financial advisor). (iii) In addition to the
obligations of Company set forth in paragraph (i) of this Section 5.4(a),
Company as promptly as practicable, and in any event within 24 hours, shall
advise PETREX orally and in writing of any request for information which Company
reasonably believes would lead to an Acquisition Proposal or of any Acquisition
Proposal, or any inquiry with respect to or which Company reasonably believes
would lead to any Acquisition Proposal, the material terms and conditions of
such request, Acquisition Proposal or inquiry, and the identity of the person or
group making any such request, Acquisition Proposal or inquiry. Company will
keep PETREX informed in all material respects of the status and details
(including material amendments or proposed amendments) of any such request,
Acquisition Proposal, or inquiry. In addition to the foregoing, Company shall
(A) provide PETREX with at least 48 hours prior notice (or such lesser prior
notice as provided to the members of Company's Board of Directors but in no
event less than eight hours) of any meeting of Company's Board of Directors at
which Company's Board of Directors is reasonably expected to consider an
Acquisition Proposal and (B) provide PETREX with at least three (3) business
days prior written notice of a meeting of Company's Board of Directors at which
Company's Board of Directors is reasonably expected to recommend a Superior
Proposal to its shareholders and together with such notice a copy of the
definitive documentation relating to such Superior Proposal.

         5.5      PUBLIC DISCLOSURE.

         PETREX and Company will consult with each other and agree before
issuing any press release or otherwise making any public statement with respect
to the Merger, this Agreement or an Acquisition Proposal and will not issue any
such press release or make any such public statement prior to such agreement,
except as may be required by law or any listing agreement with a national
securities exchange, in which case reasonable efforts to consult with the other
party will be made prior to any such release or public statement. The parties
have agreed to the text of the joint press release announcing the signing of
this Agreement.

         5.6      REASONABLE EFFORTS; NOTIFICATION.

         (a) Upon the terms and subject to the conditions set forth in this
Agreement, each of the parties agrees to use commercially reasonable efforts to
take, or cause to be taken, all actions, and to do, or cause to be done, and to
assist and cooperate with the other parties in doing, all things necessary,
proper or advisable to consummate and make effective, in the most expeditious
manner practicable, the Merger and the other transactions contemplated by this
Agreement, including using commercially reasonable efforts to accomplish the
following: (i) the taking of all reasonable acts necessary to cause the
conditions precedent set forth in Article VI to be satisfied, (ii) the obtaining
of all necessary actions or nonactions, waivers, consents, approvals, orders and
authorizations from Governmental Entities and the making of all necessary
registrations, declarations and filings (including registrations, declarations
and filings with Governmental Entities, if any) and the taking of all reasonable

                                       26


steps as may be necessary to avoid any suit, claim, action, investigation or
proceeding by any Governmental Entity, (iii) the obtaining of all necessary
consents, approvals or waivers from third parties, (iv) the defending of any
suits, claims, actions, investigations or proceedings, whether judicial or
administrative, challenging this Agreement or the consummation of the
transactions contemplated hereby, including seeking to have any stay or
temporary restraining order entered by any court or other Governmental Entity
vacated or reversed and (v) the execution or delivery of any additional
instruments necessary to consummate the transactions contemplated by, and to
fully carry out the purposes of, this Agreement. In connection with and without
limiting the foregoing, Company and its Board of Directors shall, if any state
takeover statute or similar statute or regulation is or becomes applicable to
the Merger, this Agreement, the Company Voting Agreements or any of the
transactions contemplated hereby and thereby, use commercially reasonable
efforts to ensure that the Merger, this Agreement, the Company Voting Agreements
and the other transactions contemplated hereby and thereby may be consummated as
promptly as practicable on the terms contemplated by this Agreement and
otherwise to minimize the effect of such statute or regulation on the Merger,
this Agreement, the Company Voting Agreements and the transactions contemplated
hereby and thereby. Notwithstanding anything herein to the contrary, nothing in
this Agreement shall be deemed to require PETREX or Company or any subsidiary or
affiliate thereof to agree to any divestiture by itself or any of its affiliates
of shares of capital stock or of any business, assets or property, or the
imposition of any material limitation on the ability of any of them to conduct
their business or to own or exercise control of such assets, properties and
stock.

         (b) Company shall give prompt notice to PETREX of any representation or
warranty made by it contained in this Agreement becoming untrue or inaccurate,
or any failure of Company to comply with or satisfy in any material respect any
covenant, condition or agreement to be complied with or satisfied by it under
this Agreement, in each case, such that the conditions set forth in Section
6.3(a) or 6.3(b) would not be satisfied; provided, however, that no such
notification shall affect the representations, warranties, covenants or
agreements of the parties or the conditions to the obligations of the parties
under this Agreement.

         (c) PETREX shall give prompt notice to Company of any representation or
warranty made by it contained in this Agreement becoming untrue or inaccurate,
or any failure of PETREX to comply with or satisfy in any material respect any
covenant, condition or agreement to be complied with or satisfied by it under
this Agreement, in each case, such that the conditions set forth in Section
6.2(a) or 6.2(b) would not be satisfied; provided, however, that no such
notification shall affect the representations, warranties, covenants or
agreements of the parties or the conditions to the obligations of the parties
under this Agreement.

         5.7      THIRD- PARTY CONSENTS.

         As soon as practicable following the date hereof, PETREX and Company
will each use commercially reasonable efforts to obtain any consents, waivers
and approvals under any of its or its subsidiaries' respective agreements,
contracts, licenses or leases required to be obtained in connection with the
consummation of the transactions contemplated hereby.

         5.8      STOCK OPTIONS; WARRANTS.

         (a) At the Effective Time, each outstanding option or warrant to
purchase shares of Company Common Stock (each, a "COMPANY STOCK OPTION"),
whether or not vested, and each outstanding Company Warrant, whether or not then
exercisable, shall be converted into options or warrants to purchase PETREX
Common Stock or stock appreciation rights to purchase PETREX Common Stock.

         (b) PETREX shall cause employees of Company and its subsidiaries as of
the Effective Time ("AFFECTED EMPLOYEES") to be credited with service with
Company and each of its subsidiaries for purposes of eligibility and vesting
under each employee benefit plan maintained by PETREX or its subsidiaries after
the Effective Time to the extent of their service with Company provided,
however, that such service shall not be recognized to the extent that such
recognition would result in duplication of benefits. To the extent permitted by
the PETREX Plans and applicable law, PETREX will, or will cause Company to (i)
waive all limitations as to preexisting conditions, exclusions and waiting
periods with respect to participation and coverage requirements applicable to
the Affected Employees under any welfare benefit plans that such employees may
be eligible to participate in after the Effective Time, other than limitations

                                       27


or waiting periods that are already in effect with respect to such employees and
that have not been satisfied as of the Effective Time under any welfare plan
maintained for the Affected Employees immediately prior to the Effective Time,
and (ii) provide each Affected Employee with credit for any co-payments and
deductibles paid prior to the Effective Time in satisfying any applicable
deductible or out-of-pocket requirements under any welfare plans that such
employees are eligible to participate in after the Effective Time.

         5.9      [Reserved].

         5.10     PINK SHEETS LISTING.

         PETREX agrees to file with the PINK SHEETS, if necessary, a
Notification Form for Listing of Additional Shares with regards to the shares of
PETREX Common Stock issuable, and those required to be reserved for issuance, in
connection with the Merger.

         5.11     AFFILIATES.

         Set forth in Company Schedule 5.11 is a list of those persons who may
be deemed to be, in Company's reasonable judgment, affiliates of Company within
the meaning of Rule 145 promulgated under the Securities Act (each, a "COMPANY
AFFILIATE"). Company will promptly provide PETREX with updates to such list with
respect to persons who may deemed, after the date hereof, to be Company
Affiliates. Company has provided to PETREX (with respect to current Company
Affiliates), and will use its commercially reasonable efforts to deliver or
cause to be delivered to PETREX, as promptly as practicable on or following the
date any person who subsequently becomes a Company Affiliate, from each person
who becomes a Company Affiliate after the date hereof, an executed affiliate
agreement in substantially the form attached hereto as Exhibit C (the "AFFILIATE
AGREEMENT"), each of which will be in full force and effect as of the Effective
Time. PETREX will be entitled to place appropriate legends on the certificates
evidencing any PETREX Common Stock to be received by a Company Affiliate
pursuant to the terms of the Affiliate Agreement, and to issue appropriate stop
transfer instructions to the transfer agent for the PETREX Common Stock,
consistent with the terms of the Affiliate Agreement.

otherwise prohibiting consummation of the Merger.

received a certificate with respect to the foregoing signed on behalf of PETREX

Effect on the Company provided, however, that such Material Adverse Effect
qualifier shall be inapplicable with respect to the representations and
warranties contained in Section 2.2 and 2.20 (which representations and
warranties shall have been true and correct in all material respects as of the

or agreement on the part of PETREX set forth in this Agreement, or if any

such that the conditions set forth in Section 6.2(a) or Section 6.2(b) would not
be satisfied as of the time of such breach or as of the time such representation

such breach, provided PETREX continues to exercise best efforts to cure such
breach (it being understood that Company may not terminate this Agreement

thirty (30)-day period);

         (f) by PETREX, upon a breach of any representation, warranty, covenant
or agreement on the part of Company set forth in this Agreement, or if any

satisfied as of the time of such breach or as of the time such representation or
warranty shall have become untrue, provided, that if such inaccuracy in

         8.3      INTERPRETATION; DEFINITIONS.

         (a) When a reference is made in this Agreement to Exhibits, such
reference shall be to an Exhibit to this Agreement unless otherwise indicated.
When a reference is made in this Agreement to Sections, such reference shall be
to a Section of this Agreement. Unless otherwise indicated the words "include,"
"includes" and "including" when used herein shall be deemed in each case to be
followed by the words "without limitation." The table of contents and headings

         (b) For purposes of this Agreement:

         (i) the term "KNOWLEDGE" means with respect to a party hereto, with
respect to any matter in question, the actual knowledge of the executive
officers of such party;

         (ii) the term "MATERIAL ADVERSE EFFECT" when used in connection with an

and its subsidiaries taken as a whole; provided, however, that in no event shall
(A) a decrease in such entity's stock price or the failure to meet or exceed
Wall Street research analysts' or such entity's internal earnings or other
estimates or projections in and of itself constitute a Material Adverse Effect
or (B) any change, event, violation, inaccuracy, circumstance or effect that
results from (x) changes affecting the industry in which such entity operates
generally (which changes do not disproportionately affect such entity), (y)
changes affecting the United States economy generally or (z) the public
announcement or pendency of the Merger, constitute a Material Adverse Effect;

         (iii) the term "PERSON" shall mean any individual, corporation

partnership, limited liability partnership, joint venture, estate, trust,
company (including any limited liability company or joint stock company), firm

                                       32


         8.4      COUNTERPARTS.

         This Agreement may be executed in one or more counterparts, all of
which shall be considered one and the same agreement and shall become effective
when one or more counterparts have been signed by each of the parties and
delivered to the other party, it being understood that all parties need not sign
the same counterpart.

         8.5      ENTIRE AGREEMENT; THIRD PARTY BENEFICIARIES.

         This Agreement and the documents and instruments and other agreements
among the parties hereto as contemplated by or referred to herein, including the
Company Schedules and the PETREX Schedules (a) constitute the entire agreement
among the parties with respect to the subject matter hereof and supersede all
prior agreements and understandings, both written and oral, among the parties
with respect to the subject matter hereof, it being understood that the
Confidentiality Agreement shall continue in full force and effect until the
Closing and shall survive any termination of this Agreement; and (b) are not
intended to confer upon any other person any rights or remedies hereunder.

         8.6      SEVERABILITY.

         In the event that any provision of this Agreement, or the application
thereof, becomes or is declared by a court of competent jurisdiction to be
illegal, void or unenforceable, the remainder of this Agreement will continue in
full force and effect and the application of such provision to other persons or
circumstances will be interpreted so as reasonably to effect the intent of the
parties hereto. The parties further agree to replace such void or unenforceable
provision of this Agreement with a valid and enforceable provision that will
achieve, to the extent possible, the economic, business, and other purposes of
such void or unenforceable provision.

         8.7      OTHER REMEDIES; SPECIFIC PERFORMANCE.

         Except as otherwise provided herein, any and all remedies herein
expressly conferred upon a party will be deemed cumulative with and not
exclusive of any other remedy conferred hereby, or by law or equity upon such
party, and the exercise by a party of any one remedy will not preclude the
exercise of any other remedy. The parties hereto agree that irreparable damage
would occur in the event that any of the provisions of this Agreement were not
performed in accordance with their specific terms or were otherwise breached. It
is accordingly agreed that the parties shall be entitled to seek an injunction
or injunctions to prevent breaches of this Agreement and to enforce specifically
the terms and provisions hereof in any court of the United States or any state
having jurisdiction, this being in addition to any other remedy to which they
are entitled at law or in equity.

         8.8      GOVERNING LAW.

         This Agreement shall be governed by and construed in accordance with
the laws of the State of Nevada, regardless of the laws that might otherwise
govern under applicable principles of conflicts of law thereof.

         8.9      ARBITRATION.

         If a dispute should arise, all claims, disputes, controversies,
differences or other matters in question arising out of the Agreement to each
other in the matters stated in this Agreement (the claims) shall be settled
finally, completely and conclusively by arbitration in Salt Lake County, Utah,
in accordance with the Commercial Arbitration Rules of the American Arbitration
Association (the "Rules"), by one or more arbitrators chosen in accordance with
the Rules. Arbitration shall be initiated by written demand by the party seeking
arbitration. This Agreement to arbitrate shall be specifically enforceable only
in the District Court of Salt Lake County, Utah. A decision of the arbitrator or
arbitrators shall be final, conclusive and binding on PETREX and the Company,
and judgment may be entered thereon in the District Court of Salt Lake County,
Utah, to enforce such decision and the benefits thereof. Upon appointment, the
arbitrators shall then proceed to decide the arbitration subjects in accordance
with the Rules. Any arbitration held in accordance with this paragraph shall be

                                       33


private and confidential and no person shall be entitled to attend the hearings
except the arbitrator(s), the stenographer, if one is requested, PETREX,
Company, and any designated representatives of the parties. The matters
submitted for arbitration, the hearings and proceedings thereunder and the
arbitration award shall be kept and maintained in strictest confidence by the
parties and shall not be discussed, disclosed or communicated to any persons. On
request of either party, the record of the proceeding shall be sealed and may
not be disclosed except insofar, and only insofar, as may be necessary to
enforce the award of the arbitrators and any judgment enforcing such award. If
counsel is required to seek the enforcement of this agreement or this particular
section, counsel shall be entitled to recover its (his) reasonable and necessary
attorneys' fees and costs from the opposing party.

         8.10     RULES OF CONSTRUCTION.

         The parties hereto agree that they have been represented by counsel
during the negotiation and execution of this Agreement and, therefore, waive the
application of any law, regulation, holding or rule of construction providing
that ambiguities in an agreement or other document will be construed against the
party drafting such agreement or document.

         8.11     ASSIGNMENT.

         No party may assign either this Agreement or any of its rights,
interests, or obligations hereunder without the prior written approval of the
other parties. Subject to the preceding sentence, this Agreement shall be
binding upon and shall inure to the benefit of the parties hereto and their
respective successors and permitted assigns.




                                       34



         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
