Mr. Jack Menache
Vice President Administration
Peak International Limited

P.O. Box 1767

U.S.A.

Dear Mr. Menache,

RE: INDUSTRIAL DEVELOPMENT - KANGLE INDUSTRIAL CITY, HENGGANG TOWN, LONGGANG
    DISTRICT, SHENZHEN, PR CHINA

Further to our inspection and discussions regarding the above mentioned
development we would like to propose the following two options for your
consideration.

Option 1
--------

Agency

FPDSavills to be appointed for a period of 6 months as your consultant, advisor
and exclusive agent for the disposal of the property, (subject to the exclusion
described below).

Function & Duties of FPDSavills

(a)  Identifying prospective purchaser/tenants for the Development and
conducting personalised mailshots, cold call campaigns, co-ordinating approved
media advertising, and using best endeavors to create opportunities to commence
dialogue with decision makers of targeted companies.

(b)  When necessary and appropriate, market the Development to prospects
overseas, by making use of it's international office associates, it's US network
- Trammell Crow Company or such other contacts to achieve global coverage and
marketing of the Development when necessary.

(c)  In consultation with PEAK, FPDSavills will prepare, develop and implement a
marketing programme appropriate to the prevailing market conditions.

(d)  Advise on the current market conditions with regard to rents, sale prices
and payment terms.

(e)  Advise on the suitability of subdivision.

<PAGE>
                                                                      2

(f)  To position the development in the market and ensure that PEAK is kept
informed to allow response to changing market conditions.

(g)  To coordinate all enquiries in conjunction with PEAK and to negotiate
acceptable terms and conditions.

(h)  To report the progress of the disposal on bi-weekly basis.

Method of Disposal

Although we will be principally pursuing a vacant possession sale on a whole lot
basis, we will keep other options open. We believe that to lease out the whole
lot or subdivide into three sections vertically is sound in the current market.

We suggest the property be marketed by way of Private Treaty. Private Treaty
will allow us to fully explore each inquiry and to offer the greatest degree of
flexibility to PEAK and interested parties.

Marketing

The principal method of marketing will involve direct contact with potential
users. FPDSavills have a database of over 50,000 companies covering all business
sectors, size and country of origin. We will select 500 of them from our
database. The first tear targets (100 companies) will be contacted and the
property will be presented to them.

The marketing campaign will also include the following :

(a)  Flyer
     -----

         We recommend that 1,000 copies of a high quality A4 size flyer should
         be produced which will create an immediate image of quality and
         prestige for this development, whilst remaining informative. The flyer
         will be distributed to the wider selection of companies from our
         database including overseas prospects.

(b)  Web-site
     --------

         We will put the development on to our corporate web site. A photograph
         and full development details will be included to facilitate further
         enquiry from the www.

         With your consent, we will list the property in the Shenzhen Real
         Estate Exchange Centre. The exchange centre is a government web site
         and exchange centre for property transactions.

(c)  Press Advertising
     -----------------
         We would recommend using the following publications:

<PAGE>
                                                                      3

         Newspaper:    South China Morning Post - Major English newspaper in HK
                       Hong Kong Economic Times - Major Chinese business post in
                       HK Shenzhen Special Zone Daily - Major daily in Shenzhen

(d)  Cold-calling
     ------------

         Whilst many of our competitors wait for their telephones to ring in
         response to a press advertisement, staff at FPDSavills carry out a
         pro-active marketing campaign through cold-calling which achieves
         impressive results.

(e)  Banner
     ------

         We wish to erect one large banner on the building. This banner will be
         of a high quality and striking design and will include FPDSavills
         telephone numbers.

(f)  Press Releases
     --------------

         FPDSavills, with assistance from a P.R. consultancy, will draft press
         releases throughout the marketing campaign and will use its strong
         connections with the Press to ensure that there is plenty of coverage
         for the project.

Target Market

We believe the most likely purchaser/tenant will be an end-user who requires
immediate space. Our target market would be :

(a) Large industrial space users who currently operate in Shenzhen or Guangdong
area;

(b) MNC with an immediate requirement in the area.

(c) Large warehouse space users operating in the area.

Other than the end users, we will also target the main developers in Shenzhen.

Marketing Cost

As part of our services, FPDSavills will execute the marketing campaign. The
cost of the marketing tools will not exceed the amounts set forth below unless
Peak gives its prior written (email acceptable) consent Any cost in excess of
the amount set forth below not approved by Peak shall be borne by FPD Savills:

Fees

A commission of 1.25% of the purchase price (or 0.75% from each of Peak and the
buyer) will be charged upon the closing of an agreement. Alternatively, the
first one and a half months rental shall be paid to Agent. To allow us to
apportion the substantial time necessary for the success of the project and to
cover the expenses relating to time and travel to Shenzhen we propose a monthly
retainer fee of HK$30,000 for November and December, and HK$20,000 thereafter.
This fee will be deducted from the commission upon the successful disposal.
Agent shall bear all of its own expenses incurred in performing its duties
hereunder.

Exclusion: Notwithstanding anything to the contrary herein, no commission shall
be payable and this agreement shall terminate in the event that Peak enters into
a letter of intent or other agreement with Shenzhen Henggang Economic
Development Corporation (or its related companies) for the sale, lease or other
disposal of the property. In the event of such transaction, Peak will pay an
additional amount to Agent in the amount of 50% of the retainer theretofore
paid.

The reasons we request retainers for China work is that the volume of work
involved in marketing a property in China far exceeds that of a similar property
in Hong Kong. The market in China is not mature and every facet of the job is
affected from initial statutory searches through to the final sale contracts;
everything takes more time and effort. To dedicate the volume of time necessary
to effectively market a project of this nature it is essential that we have the
retainer in place.

To try to give you a better understanding of how time is valued in Hong Kong I
have attached hereto our rate on hourly charge and obtained some comparative
hourly charge rates from other professional service providers for your
reference. The cost of transportation is also attached for your reference.

We are very keen to be appointed on this project. However without the retainer
we will be unable to dedicate the time we believe is required from a sole and
exclusive agent operating from Hong Kong.

Option 2

FPDSavills to be appointed on general agent (non-exclusive) basis for a period
of 6 month with a clause to terminate the instruction by giving the other party
one-month advance notice.

The main function and Duties of the Agent is to introducing prospective
tenant/purchaser to the development. FPDSavills will market the development on a
re-active basis. The office in Shenzhen and/or Guangzhou will run this.

Fee

A commission of 1.5% of the purchase price or one and a half month rental
whichever applicable will be charged upon a successful disposal.

I believe the above is in order. Michael and I are looking forward to working
with you in the near future.

Yours sincerely,
For and on behalf of
FPDSavills (Hong Kong) Limited

outstanding immediately prior to the Effective Time, other than any shares of

applicable restricted stock purchase agreement or other agreement with the
Company, then, subject to the terms of the plan or agreement pursuant to which
such shares were issued, the shares of PETREX Common Stock issued in exchange

purchase Company Common Stock are listed as Schedule 1.6(c).

         (d) FRACTIONAL SHARES. No fraction of a share of PETREX Common Stock

                                       4
<PAGE>

Agent and shall contain such other provisions as PETREX may reasonably specify)
and (ii) instructions for use in effecting the surrender of the Certificates in
exchange for certificates representing shares of PETREX Common Stock and any
dividends or other distributions pursuant to Section 1.7(d). Upon surrender of
Certificates for cancellation to the Exchange Agent or to such other agent or
agents as may be appointed by PETREX, together with such letter of transmittal,
duly completed and validly executed in accordance with the instructions thereto,
the holders of such Certificates shall be entitled to receive in exchange
therefore certificates representing the number of whole shares of PETREX Common
Stock into which their shares of Company Common Stock were converted at the
Effective Time and any dividends or distributions payable pursuant to Section
1.7(d), and the Certificates so surrendered shall forthwith be cancelled. Until
so surrendered, outstanding Certificates will be deemed from and after the
Effective Time, for all corporate purposes, subject to Section 1.7(d) as to the
payment of dividends and other distributions, to evidence only the ownership of
the number of full shares of PETREX Common Stock into which such shares of
Company Common Stock shall have been so converted.

         (d) DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES. No dividends or
other distributions declared or made after the date of this Agreement with
respect to PETREX Common Stock with a record date after the Effective Time will
be paid to the holders of any unsurrendered Certificate(s) with respect to the
shares of PETREX Common Stock represented thereby until the holders of record of
such Certificate(s) shall surrender such Certificate(s). Subject to applicable
law, following surrender of any such Certificate(s), the Exchange Agent shall
deliver to the record holders thereof, without interest, a certificate(s)
representing whole shares of PETREX Common Stock issued in exchange therefore
along with the amount of any such dividends or other distributions with a record
date after the Effective Time payable with respect to such whole shares of
PETREX Common Stock.

         (e) TRANSFERS OF OWNERSHIP. If any certificate representing shares of
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
properly endorsed and otherwise in proper form for transfer and that the persons
requesting such exchange will have paid to PETREX or any agent designated by it
any transfer or other taxes required by reason of the issuance of certificates
representing shares of PETREX Common Stock in any name other than that of the
registered holder of the Certificates surrendered, or established to the
satisfaction of PETREX or any agent designated by it that such tax has been paid
or is not payable.

         (f) REQUIRED WITHHOLDING. Each of the Exchange Agent, PETREX, and the
Surviving Corporation shall be entitled to deduct and withhold from any
consideration payable or otherwise deliverable pursuant to this Agreement to any
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.

         (g) NO LIABILITY. Notwithstanding anything to the contrary in this
Section 1.7, none of the Exchange Agent, PETREX, the Surviving Corporation, or
any party hereto shall be liable to a holder of shares of PETREX Common Stock or
Company Common Stock for any amount properly paid to a public official pursuant
to any applicable abandoned property, escheat or similar law.

         1.8      NO FURTHER OWNERSHIP RIGHTS IN COMPANY COMMON STOCK.

         All shares of PETREX Common Stock issued upon the surrender for
exchange of shares of Company Common Stock in accordance with the terms hereof
(together with any cash paid in respect thereof pursuant to Section 1.7(d))

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

Transaction on the terms proposed, and (y) Company's Board of Directors shall

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

Acquisition Proposal and (B) provide PETREX with at least three (3) business

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
<PAGE>

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.

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

breach (it being understood that Company may not terminate this Agreement
pursuant to this paragraph (e) if such breach by PETREX is cured during such
thirty (30)-day period);

         (f) by PETREX, upon a breach of any representation, warranty, covenant

by its shareholders of an Acquisition Proposal involving a tender offer or
exchange offer) or (B) failed to reconfirm its approval and recommendation of
this Agreement and the transactions contemplated hereby within five business
days thereafter or (v) the Board of Directors of Company resolves to take any of
the actions described above;

         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

         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

such void or unenforceable provision.

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

         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

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.

         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
