                              MKS INSTRUMENTS, INC.

              AMENDED AND RESTATED 1997 DIRECTOR STOCK OPTION PLAN

1.    Purpose.

      The purpose of this Amended and Restated 1997 Director Stock Option Plan
(the "Plan") of MKS Instruments, Inc., a Massachusetts corporation (the
"Company"), is to encourage ownership in the Company by non-employee directors
of the Company whose continued services are considered essential to the
Company's future progress and to provide them with a further incentive to remain
as directors of the Company.

2.    Administration.

      The Board of Directors shall supervise and administer the Plan. Grants of
stock options under the Plan and the amount and nature of the awards to be
granted shall be automatic in accordance with Section 5. However, all questions
of interpretation of the Plan or of any options issued under it shall be
determined by the Board of Directors and such determination shall be final and
binding upon all persons having an interest in the Plan.

3.    Participation in the Plan.

      Directors of the Company who are not employees of the Company or any
subsidiary of the Company shall be eligible to participate in the Plan.

4.    Stock subject to the Plan.

      (a) Definition of Common Stock. "Common Stock" means (i) prior to the
closing of the Company's initial public offering of common stock pursuant to an
effective registration statement under the Securities Act of 1933 ("IPO"), the
Class B Common Stock, no par value per share, of the Company, and (ii) from and
after the closing of the IPO, the Common Stock, no par value per share, of the
Company.

      (b) The maximum number of shares of the Company's Common Stock which may
be issued under the Plan shall be 200,000 shares, subject to adjustment as
provided in Section 7. All share amounts set forth in this Plan reflect all
stock splits effected prior to April 16, 2003 (the "Restatement Date").

      (c) If any outstanding option under the Plan for any reason expires or is
terminated without having been exercised in full, the shares allocable to the
unexercised portion of such option shall again become available for grant
pursuant to the Plan.

      (d) All options granted under the Plan shall be nonstatutory options not
entitled to special tax treatment under Section 422 of the Internal Revenue Code
of 1986, as amended to date and as it may be amended from time to time (the
"Code").

5.    Terms, Conditions and Form of Options.

      Each option granted under the Plan shall be evidenced by a written
agreement in such form as the Board of Directors shall from time to time
approve, which agreements shall comply with and be subject to the following
terms and conditions:
<PAGE>
      (a) Option Grant Dates. Options shall automatically be granted to all
eligible outside directors as follows:

            (i) each person who first becomes an eligible outside director after
the Restatement Date shall be granted an option to purchase 20,000 shares of
Common Stock on the date of his or her initial election to the Board of
Directors; and

            (ii) each eligible outside director then in office on the date of
each annual meeting of stockholders of the Company shall be granted an
additional option to purchase 12,000 shares of Common Stock on the date of each
such annual meeting of stockholders, provided that he or she was elected to
serve as a director of the Company at least six months prior to the date of such
meeting.

      (b) Option Exercise Price. The option exercise price per share for each
option granted under the Plan shall equal (i) the last reported sales price per
share of the Company's Common Stock on the Nasdaq National Market (or, if the
Common Stock is traded on a national securities exchange on the date of grant,
the reported closing sales price per share of the Common Stock on such exchange)
on the date of grant (or if no such price is reported on such date such price as
reported on the nearest preceding day), (ii) if the Common Stock is not traded
on the Nasdaq National Market or a national securities exchange, the fair market
value per share on the date of grant as determined by the Board of Directors or
(iii) the average of the closing bid and asked prices in the over-the-counter
market.

      (c) Transferability of Options. Except as the Board of Directors of the
Company may otherwise determine or provide in a written agreement entered into
in connection with the grant of an option under the Plan, options shall not be
sold, assigned, transferred, pledged or otherwise encumbered by the Optionee,
either voluntarily or by operation of law except by will or the laws of descent
and distribution, and during the life of the optionee and shall be exercisable
only by him. Reference to an optionee, to the extent relevant in the context,
shall include references to authorized transferees.

      (d) Vesting Period. Except as the Board may otherwise determine or provide
in a written agreement entered into in connection with the grant of an option
under the Plan, each option granted pursuant to paragraph (a)(i) of this Section
5 shall become exercisable in twelve (12) equal quarterly installments following
the date of grant. Each option granted pursuant to paragraph (a)(ii) of this
Section 5 shall become fully exercisable on the day prior to the first annual
meeting of stockholders of the Company following the date of grant (or if no
such meeting is held within thirteen (13) months after the date of grant, on the
thirteen-month anniversary of the date of grant).

      (e) Termination. Upon termination of an optionee's service as a director
of the Company, each option held by him which was granted prior to the
Restatement Date may be exercised during the three-month period following such
termination of service and each option held by him which was granted on or after
the Restatement Date may be exercised during the one-year period following such
termination of service, in each case as to the exercisable portion of such
option as of the date of termination, provided that (i) no option may be
exercised more than ten (10) years after the date of grant and (ii) in the event
an optionee ceases to serve as a director due to his death or disability (within
the meaning of Section 22(e)(3) of the Code or any successor provision), each
option may be exercised, with respect to options granted prior to the
Restatement Date, within the period of 180 days following the date the optionee
ceases to serve as a director, and, with respect to options granted on or after
the Restatement Date, within the one-year period following the date the optionee
ceases to serve as a director, in each case by the optionee or by the person to
whom the option is transferred by will, by the laws of descent and distribution,
or by written notice, as to the portion of the option that is exercisable on the
date of death or disability and as to the additional portion that would have
become exercisable on the next anniversary date of the date of grant of such
option.
<PAGE>
      (f) Exercise Procedure. Options may be exercised only by written notice to
the Company at its principal office accompanied by (i) payment in cash of the
full consideration for the shares as to which they are exercised or (ii) an
irrevocable undertaking, in form and substance satisfactory to the Company, by a
broker to deliver promptly to the Company sufficient funds to pay the exercise
price or delivery of irrevocable instructions, in form and substance
satisfactory to the Company, to a broker to deliver promptly to the Company cash
or a check sufficient to pay the exercise price.

      (g) Exercise by Representative Following Death of Director. An optionee,
by written notice to the Company, may designate one or more persons (and from
time to time change such designation), including his or her legal
representative, who, by reason of the director's death, shall acquire the right
to exercise all or a portion of the option. If the person or persons so
designated wish to exercise any portion of the option, they must do so within
the term of the option as provided herein. Any exercise by a representative
shall be subject to the provisions of the Plan.

6.    Limitation of Rights.

      (a) No Right to Continue as a Director. Neither the Plan, nor the granting
of an option nor any other action taken pursuant to the Plan, shall constitute
or be evidence of any agreement or understanding, express or implied, that the
Company will retain the optionee as a director for any period of time.

      (b) No Stockholders' Rights for Options. An optionee shall have no rights
as a stockholder with respect to the shares covered by his options until the
date of the issuance to him of a stock certificate therefor, and no adjustment
will be made for dividends or other rights (except as provided in Section 7) for
which the record date is prior to the date such certificate is issued.

7.    Changes in Common Stock.

      (a) If, at any time after the Restatement Date, the outstanding shares of
Common Stock are increased, decreased or exchanged for a different number or
kind of shares or other securities, or if additional shares or new or different
shares or other securities are distributed with respect to such shares of Common
Stock or other securities, through merger, consolidation, sale of all or
substantially all of the assets of the Company, reorganization,
recapitalization, reclassification, stock dividend, stock split, reverse stock
split or other distribution with respect to such shares of Common Stock, or
other securities, an appropriate and proportionate adjustment will be made in
(i) the maximum number and kind of shares reserved for issuance under the Plan,
(ii) the number and kind of shares or other securities issuable pursuant to
Sections 5(a)(i) and 5(a)(ii) above, (iii) the number and kind of shares or
other securities subject to then outstanding options under the Plan and (iv) the
price for each share subject to any then outstanding options under the Plan,
without changing the aggregate purchase price as to which such options remain
exercisable. No fractional shares will be issued under the Plan on account of
any such adjustments.

      (b) In the event of (i) a consolidation, merger or other reorganization in
which all of the outstanding shares of Common Stock are exchanged for
securities, cash or other property of any other corporation or business entity
or (ii) any sale of all or substantially all of the Company's assets (in either
event, an "Acquisition"), all options outstanding under the Plan immediately
prior to the effective date of such Acquisition shall become automatically
exercisable in full upon the effective date of such Acquisition.

8.    Amendment of the Plan.

      The Board of Directors may suspend or discontinue the Plan or revise or
amend it in any respect whatsoever; provided, however, that without approval of
the stockholders of the Company no revision or amendment shall change the number
of shares subject to the Plan (except as provided in Section 7).

9.    Notice.

Genghai Shareholders signatory hereto each desires to exchange all of their
respective shares of Genghai capital stock solely for shares of Centre Common
Stock in the respective amounts set forth herein.

         Prior to the date hereof, the respective board of directors or
analogous governing body of each of Centre and Genghai have approved and adopted
this Agreement, and it is the intent of the parties hereto that the transactions
contemplated hereby be structured so as to qualify as a tax-free exchange under
Subchapter C of the Internal Revenue Code of 1986, as amended (the "IRC"), and
the provisions of this Agreement will be interpreted in a manner consistent with
this intent.

         NOW, THEREFORE, in consideration of the premises and mutual
representations, warranties, and covenants herein contained, the parties hereto
hereby agree as follows:

                         REPRESENTATIONS AND WARRANTIES

         SECTION 2.01 REPRESENTATIONS AND WARRANTIES OF CENTRE. Centre hereby
represents and warrants to, and agrees with, Genghai and the Genghai
Shareholders:

         (a) Organization and Qualification. Centre has no subsidiaries or
affiliated corporation or owns any interest in any other enterprise (whether or
not such enterprise is a corporation). Centre is a corporation duly organized,
validly existing, and in good standing under the laws of the State of Nevada,
with all requisite power and authority, and all necessary consents,
authorizations, approvals, orders, licenses, certificates, and permits of and
from, and declarations and filings with, all federal, state, local, and other
governmental authorities and all courts and other tribunals, to own, lease,
license, and use its properties and assets and to carry on the businesses in
which it is now engaged and the businesses in which it contemplates engaging.
Centre is duly qualified to transact the businesses in which it is engaged and
is in good standing as a foreign corporation in every jurisdiction in which its
ownership, leasing, licensing, or use of property or assets or the conduct of
its businesses makes such qualification necessary.

         (b) Capitalization. The authorized capital stock of Centre consists of
50,000,000 shares of Centre Common Stock, of which 7,627,050 shares are
outstanding. Each of such outstanding shares of Centre Common Stock is validly
authorized, validly issued, fully paid, and nonassessable, has not been issued
and is not owned or held in violation of any preemptive or similar right of
stockholders and is owed by the owner set forth in Section A of the letter, of
even

                                      -3-
<PAGE>

date herewith, from Centre to Genghai and the Genghai Shareholders (the "Centre
Disclosure Letter"), which letter shall be completed and delivered to Genghai
and the Genghai Shareholders on or prior to July 15, 2003 (the "Due Diligence
Date") in each case free and clear of all liens, security interests, pledges,
charges, encumbrances, stockholders' agreements, and voting trusts. Except as
described in Section A of the Centre Disclosure Letter, there is no commitment,
plan, or arrangement to issue, and no outstanding option, warrant, or other
right calling for the issuance of, any share of capital stock of Centre or any
security or other instrument convertible into, exercisable for, or exchangeable
for capital stock of Centre. Except as described in Section A of the Centre
Disclosure Letter, there is outstanding no security or other instrument
convertible into or exchangeable for capital stock of Centre.

         (c) Financial Condition. Centre has delivered, or on or prior to the
Due Diligence Date shall deliver, to Genghai and the Genghai Shareholders true
and correct copies of the following: audited balance sheet of Centre as of
September 30, 2002; unaudited balance sheet of Centre as of March 31, 2002 and
2003; audited statements of income, statements of stockholders' equity, and
statements of cash flows of Centre for the period from February 12, 2002 (the
"Bankruptcy Termination Date") through September 30, 2002; and the unaudited
statement of income, statement of stockholders' equity, and statement of cash
flows of Centre for the six months ended March 31, 2002 and 2003. Each such
balance sheet presents fairly the financial condition, assets, liabilities, and
stockholders' equity of Centre as of its respective date; each such statement of
income and statement of stockholders' equity presents fairly the results of
operations of Centre for the period indicated; and each such statement of cash
flows presents fairly the information purported to be shown therein. The
financial statements referred to in this Section 2.01(c) have been prepared in
accordance with generally accepted accounting principles consistently applied
throughout the periods involved and are in accordance with the books and records
of Centre. Since March 31, 2003:

                  (i) There has at no time been a material adverse change in the
         financial condition, results of operations, businesses, properties,
         assets, liabilities, or future prospects of Centre.

                  (ii) Centre has not authorized, declared, paid, or effected
         any dividend or liquidating or other distribution in respect of its
         capital stock or any direct or indirect redemption, purchase, or other
         acquisition of any stock of Centre.

                  (iii) The operations and businesses of Centre have been
         conducted in all respects only in the ordinary course.

There is no fact known to Centre which materially adversely affects or in the
future (as far as Centre can reasonably foresee) may materially adversely affect
the financial condition, results of operations, businesses, properties, assets,
liabilities, or future prospects of Centre; provided, however, that Centre
expresses no opinion as to political or economic matters of general
applicability. Centre has made known, or caused to be made known, to the
accountants or auditors who have prepared, reviewed, or audited the
aforementioned consolidated financial statements all material facts and
circumstances which could affect the preparation, presentation, accuracy, or
completeness thereof.

                                      -4-
<PAGE>

         (d) Tax and Other Liabilities. Centre does not have any material
liability of any nature, accrued or contingent, including, without limitation,
liabilities for federal, state, local, or foreign taxes and penalties, interest,
and additions to tax ("Taxes"), and liabilities to customers or suppliers, other
than the following:

                  (i) Liabilities for which full provision has been made on the
         consolidated balance sheet and the notes thereto (the "Last Centre
         Balance Sheet") as of March 31, 2003 (the "Last Centre Balance Sheet
         Date") referred to in Section 2.03; and

                  (ii) Other liabilities arising since the Last Centre Balance
         Sheet Date and prior to Closing in the ordinary course of business
         (which shall not include liabilities to customers on account of
         defective products or services) which are not inconsistent with the
         representations and warranties of Centre or any other provision of this
         Agreement.

Without limiting the generality of the foregoing, the amounts set up as
provisions for Taxes on the Last Centre Balance Sheet are sufficient for all
known accrued and unpaid Taxes of Centre, whether or not due and payable and
whether or not disputed, under tax laws, as in effect on the Last Centre Balance
Sheet Date or now in effect, for the period ended on such date and for all
fiscal periods prior thereto. The execution, delivery, and performance of this
Agreement by Centre will not cause any Taxes to be payable other than by the
Genghai Shareholders or cause any lien, charge, or encumbrance to secure any
Taxes to be created either immediately or upon the nonpayment of any Taxes other
than on the properties or assets of the Genghai Shareholders. Since the
Bankruptcy Termination Date, a copy of the order (the "Bankruptcy Termination
Order") relating to which has been, or on or prior to the Due Diligence Date
will be, delivered to Genghai and the Genghai Shareholders, Centre has filed all
federal, state, local, and foreign tax returns required to be filed by it; has
delivered or, on or prior to the Due Diligence Date, will deliver to the Genghai
Shareholders a true and correct copy of each such returns which was filed since
the Bankruptcy Termination Date; has paid (or has established on the Last Centre
Balance Sheet a reserve for) all Taxes, assessments, and other governmental
charges payable or remittable by it or levied upon it or its properties, assets,
income, or franchises which are due and payable; and has delivered or, on or
prior to the Due Diligence Date, will deliver to the Genghai Shareholders a true
and correct copy of any report as to adjustments received by it from any taxing
authority since the Bankruptcy Termination Date and a statement as to any
litigation, governmental or other proceeding (formal or informal), or
investigation pending, threatened, or in prospect with respect to any such
report or the subject matter of such report.

         (e) Litigation and Claims. Except as described in Section G of the
Centre Disclosure Letter, there is no litigation, arbitration, claim,
governmental or other proceeding (formal or informal), or investigation pending,
to the best of Centre's knowledge, threatened, or in prospect (or any basis
therefor known to Centre) with respect to Centre or any of its businesses,
properties, or assets. Centre is not affected by any present or threatened
strike or other labor disturbance nor to the knowledge of Centre, is any union
attempting to represent any employee of Centre as collective bargaining agent.
Centre is not in violation of, or in default with respect to, any law, rule,
regulation, order, judgment, or decree which violation or default would have a
material adverse effect on Centre; nor is Centre required to take any action in
order to avoid such violation or default.

         (f)      Properties.

                  (i) Centre owns no real property. Centre has good title to all
         personal properties and assets material to Centre and used in its
         businesses or owned by it (except real and other properties and assets
         material to Centre as are held pursuant to leases or licenses described
         in Section B or C of the Centre Disclosure Letter), free and clear of
         all liens, mortgages, security interests, pledges, charges, and
         encumbrances (except such as are listed in Section H of the Centre
         Disclosure Letter).

                  (ii) Set forth in Section B of the Centre Disclosure Letter is
         a true and complete list of all tangible properties and assets owned by
         Centre or leased or licensed by Centre from or to a third party
         (including inventory but not including Intangibles (as hereinafter
         defined)), and with respect to such properties and assets leased or
         licensed by Centre from or to a third party, a description of such
         lease or license. All such properties and assets (including
         Intangibles) owned by Centre are reflected on the Last Centre Balance
         Sheet (except for acquisitions subsequent to the Last Centre Balance
         Sheet Date and prior to the Closing Date, which are either noted in
         Section B or C of the Centre Disclosure Letter or are approved in
         writing by Genghai). All tangible properties and assets owned by Centre
         or leased or licensed by Centre from or to a third party are in good
         and usable condition (reasonable wear and tear which is not such as to
         affect adversely the operation of the businesses of Centre excepted).

                  (iii) To the best of Centre's knowledge, no real property
         leased or licensed by Centre from or to a third party lies in an area
         which is, or will be, subject to zoning, use, or building code
         restrictions which would prohibit, and, to the best of Centre's
         knowledge, no state of facts relating to the actions or inaction of
         another person or entity or his or its ownership, leasing, or licensing
         of any real or personal property exists or will exist which would
         prevent, the continued effective ownership, leasing, or licensing of
         such real property in the businesses in which Centre is now engaged or
         the businesses in which it contemplates engaging.

                  (iv) The properties and assets (including Intangibles) owned
         by Centre (other than those leased or licensed by Centre to a third
         party) or leased or licensed by Centre from a third party constitute
         all such properties and assets which are necessary to the businesses of
         Centre as presently conducted.

                  (v) To the best knowledge of Centre, Centre has not caused or
         permitted its businesses properties, or assets to be used to generate,
         manufacture, refine, transport, treat, store, handle, dispose of,
         transfer, produce, or process any Hazardous Substance (as such term is
         defined in this Section 2.01(f)(v)), except in compliance with all
         applicable laws, rules, regulations, orders, judgments, and decrees,
         and has not caused or permitted the Release (as such term is defined in
         this Section 2.01(f)(v)) of any Hazardous Substance on or off the site
         of any property of Centre. The term "Hazardous Substance" shall mean
         any hazardous waste, as defined by 42 U.S.C. ss.6903(5), any hazardous
         substance, as defined by 42 U.S.C. ss.9601(14), any pollutant or
         contaminant, as defined by 42 U.S.C. ss.9601(33), and all toxic
         substances, hazardous materials, or other chemical substances regulated
         by

                                      -6-
<PAGE>

         any other law, rule, or regulation. The term "Release" shall have the
         meaning set forth in 42 U.S.C. ss.9601(22).

         (g) Contracts and Other Instruments. Section D of the Centre Disclosure
Letter contains a true and correct statement of the information required to be
contained therein regarding material contracts, agreements, instruments, leases,
licenses, arrangements, or understandings with respect to Centre. Centre has
furnished, or on or prior to the Due Diligence Date will furnish, to the Genghai
Shareholders (i) the certificate of incorporation (or other charter document)
and by-laws of Centre and all amendments thereto, as presently in effect, and
(ii) the following: (A) true and correct copies of all material contracts,
agreements, and instruments referred to in Section D of the Centre Disclosure
Letter; (B) true and correct copies of all material leases and licenses referred
to in Section B or C of the Centre Disclosure Letter hereto; and (C) true and
correct written descriptions of all material supply, distribution, agency,
financing, or other arrangements or understandings referred to in Section B or C
of the Centre Disclosure Letter. To the best of Centre's knowledge, neither
Centre nor (to the knowledge of Centre) any other party to any such material
contract, agreement, instrument, lease, or license is now or expects in the
future to be in violation or breach of, or in default with respect to complying
with, any term thereof, and each such material contract, agreement, instrument,
lease, or license is in full force and is (to the best of Centre's knowledge in
the case of third parties) the legal, valid, and binding obligation of the
parties thereto and (subject to applicable bankruptcy, insolvency, and other
laws affecting the enforceability of creditors' rights generally) is enforceable
as to them in accordance with its respective terms. Each such material supply,
distribution, agency, financing, or other arrangement or understanding is a
valid and continuing arrangement or understanding; neither Centre nor any other
party to any such arrangement or understanding has given notice of termination
or taken any action inconsistent with the continuance of such arrangement or
understanding; and the execution, delivery, and performance of this Agreement
will not prejudice any such arrangement or understanding in any way. Centre
enjoys peaceful and undisturbed possession under all material leases and
licenses under which it is operating. Centre is not party to or bound by any
contract, agreement, instrument, lease, license, arrangement, or understanding,
or subject to any charter or other restriction, which has had or (to the
knowledge of Centre) may in the future have a material adverse effect on the
financial condition, results of operations, businesses, properties, assets,
liabilities, or future prospects of Centre. Centre has not engaged since the
Bankruptcy Termination Date, is not engaging in, and does not intend to engage
in any transaction with, and has not had, does not now have, and does not intend
to have any material contract, agreement, instrument, lease, license,
arrangement, or understanding with, any stockholder of Centre, any director,
officer, or employee of Centre (except for employment agreements listed in
Section D of the Centre Disclosure Letter and employment and compensation
arrangements described in Section E of the Centre Disclosure Letter), any
relative or affiliate of any stockholder of Centre or of any such director,
officer, or employee, or any other corporation or enterprise in which any
stockholder of Centre, any such director, officer, or employee, or any such
relative or affiliate then had or now has a 5% or greater equity or voting or
other substantial interest, other than those listed and so specified in Section
D of the Centre Disclosure Letter. The stock ledgers and stock transfer books
relating to all issuances and transfers of stock by Centre and the minute book
records of Centre and all proceedings of the stockholders and the Board of
Directors and committees thereof of Centre since their respective incorporation
made available to counsel to Genghai and the Genghai Shareholders

                                      -7-
<PAGE>

are the original stock ledgers and stock transfer books and minute book records
of Centre or exact copies thereof. Centre is not in violation or breach of, or
in default with respect to, any term of its certificate of incorporation (or
other charter document) or by-laws.

         (h)      Employees.

                  (i) Centre does not have, or contribute to, and, since the
         Bankruptcy Termination Date, has not had and has not contributed to,
         any pension, profit-sharing, option, other incentive plan, or any other
         type of Employee Benefit Plan (as defined in Section 3(3) of the
         Employee Retirement Income Security Act of 1974, as amended ("ERISA")),
         or has any obligation to or customary arrangement with employees for
         bonuses, incentive compensation, vacations, severance pay, sick pay,
         sick leave, insurance, service award, relocation, disability, tuition
         refund, or other benefits, whether oral or written, except as set forth
         in Section E of the Centre Disclosure Letter. Centre has furnished to
         Genghai and the Genghai Shareholders: (A) true and correct copies of
         all documents evidencing plans, obligations, or arrangements referred
         to in Section E of the Centre Disclosure Letter (or true and correct
         written summaries, so initialed, of such plans, obligations, or
         arrangements to the extent not evidenced by documents) and true and
         correct copies, so initialed, of all documents evidencing trusts,
         summary plan descriptions, and any other summaries or descriptions
         relating to any such plans; (B) the two most recent annual reports
         (Form 5500's), if any, including all schedules thereto and the most
         recent annual and periodic accounting of related plan assets with
         respect to each Employee Benefit Plan; (C) the two most recent
         actuarial valuations with respect to each Pension Plan (as defined in
         Section 3(2) of ERISA) subject to Title IV of ERISA; and (D) the most
         recent determination letter issued by the Internal Revenue Service with
         respect to each Pension Plan.

                  (ii) If any Employee Benefit Plan of Centre were to be
         terminated on the day prior to Closing Date, (A) no liability under
         Title IV of ERISA would be incurred by Centre or Genghai and (B) all
         Accrued Benefits (as defined in this Section 2.01(h)(ii)) to such day
         prior to the Closing Date (whether or not vested) would be fully funded
         in accordance with the assumptions contained in the regulations of the
         Pension Benefit Guaranty Corporation governing the funding of
         terminated defined benefit plans. For purposes hereof, "Accrued
         Benefits" shall include the value of disability, pre-retirement, death
         benefits, and all supplements, subsidized, ancillary, and optional
         forms of benefits. All Accrued Liabilities (for contributions or
         otherwise) (as defined in this Section 2.01(h)(ii)) of Centre as of the
         Closing Date to each Employee Benefit Plan and with respect to each
         obligation to, or customary arrangement with, employees for bonuses,
         incentive compensation, vacations, severance pay, sick pay, sick leave,
         insurance, service award, relocation, disability, tuition refund, or
         other benefits, whether oral or written, have been paid or accrued for
         all periods ending prior to the Closing Date and no payment to any
         Employee Benefit Plan or with respect to any such obligation or
         arrangement since the Last Centre Balance Sheet Date has been
         disproportionately large compared to prior payments. For purposes
         hereof, "Accrued Liabilities" shall include a pro rata contribution to
         each Employee Benefit Plan or with respect to each such obligation or
         arrangement for that portion of a plan year or other applicable period
         which commences prior to, and ends after, the Closing Date, and Accrued

                                      -8-
<PAGE>

         Liabilities for any portion of a plan year or other applicable period
         shall be determined by multiplying the liability for the entire such
         year or period by a fraction, the numerator of which is the number of
         days preceding the Closing Date in such year or period and the
         denominator of which is the number of days in such year or period, as
         the case may be.

                  (iii) There has been no violation of the reporting and
         disclosure requirements imposed either under ERISA or the Code for
         which a penalty has been or may be imposed with respect to any Employee
         Benefit Plan of Centre. There has been no breach of fiduciary duty or
         responsibility with respect to any Employee Benefit Plan of Centre. No
         Employee Benefit Plan of Centre or related trust has any liability of
         any nature, accrued or contingent, including without limitation
         liabilities for Taxes, other than for routine payments to be made in
         due course to participants and beneficiaries, except as set forth in
         Section E of the Centre Disclosure Letter. Centre does not have any
         formal plan or commitment, whether or not legally binding, to create
         any additional or modify any existing Employee Benefit Plan or benefit
         obligation or arrangement described in Section 2.01(h)(i)). Each
         Employee Benefit Plan of Centre which is a group health plan within the
         meaning of Section 5000(b)(1) of the Code is and has been maintained in
         full compliance with the applicable requirements of Section 4980B of
         the Code. Other than the health care continuation requirements of
         Section 4980B of the Code, Centre does not have any obligation to
         provide post-retirement medical benefits or life insurance coverage or
         any deferred compensation benefits to any present or former employees.
         There is no litigation, arbitration, claim, governmental or other
         proceeding (formal or informal), or investigation pending, threatened,
         or (to the best of Centre's knowledge) in prospect (or any basis
         therefor known to Centre) with respect to any Employee Benefit Plan of
         Centre or related trust or with respect to any fiduciary,
         administrator, or sponsor (in its capacity as such) of any Employee
         Benefit Plan. No Employee Benefit Plan of Centre or related trust and
         no such obligation or arrangement is in violation of, or in default
         with respect to, any law, rule, regulation, order, judgment, which
         violation or default would have a material adverse effect thereon or
         decree nor is Centre, any Employee Benefit Plan of Centre, or any
         related trust required to take any action in order to avoid any such
         violation or default. No event has occurred, or is (to the best of
         Centre's knowledge) threatened or about to occur, which would
         constitute a prohibited transaction under Section 406 of ERISA.

                  (iv) Each Pension Plan maintained for the employees of Centre
         has been qualified, from its inception, under Section 401(a) of the
         Code and any related trust has been an exempt trust for such period
         under Section 501 of the Code. Each Pension Plan has been operated in
         accordance with its terms. No Pension Plan which is subject to Title IV
         of ERISA has an accumulated or waived funding deficiency within the
         meaning of Section 412 of the Code. No investigation or review by the
         Internal Revenue Service is currently pending or (to the knowledge of
         Centre) is contemplated in which the Internal Revenue Service has
         asserted or may assert that any Pension Plan is not qualified under
         Section 401(a) of the Code or that any related trust is not exempt
         under Section 501 of the Code. Neither Centre, nor any organization to
         which Centre is a successor or parent corporation, within the meaning
         of Section 4069(b) of ERISA, has divested itself of any entity
         maintaining or with an obligation to contribute to any Pension Plan
         which had an "amount of unfunded benefit liabilities," as defined in
         Section 4001(a)(18) of ERISA, at the time of

                                      -9-
<PAGE>

         such divestiture. No assessment of any federal taxes with respect to
         any Employee Benefit Plan of Centre has been made or (to the knowledge
         of Centre) is contemplated against Centre, or any related trust of any
         Pension Plan of Centre, and nothing has occurred which would result in
         the assessment of unrelated business taxable income under the Code with
         respect to any Employee Benefit Plan of Centre. Form 5500's have been
         timely filed with respect to all Pension Plans of Centre. No event has
         occurred or (to the knowledge of Centre) is threatened or about to
         occur which would constitute a reportable event within the meaning of
         Section 4043(b) of ERISA. No notice of termination has been filed by
         the plan administrator pursuant to Section 4041 of ERISA or issued by
         the Pension Benefit Guaranty Corporation pursuant to Section 4042 of
         ERISA with respect to any Pension Plan of Centre.

                  (v) Centre does not currently contribute to and since
         September 16, 1980 has not effectuated either a complete or partial
         withdrawal from any multiemployer Pension Plan within the meaning of
         Section 3(37) of ERISA.

                  (vi) Section E of the Centre Disclosure Letter contains a true
         and correct statement of the names, relationship with Centre, present
         rates of compensation (whether in the form of salary, bonuses,
         commissions, or other supplemental compensation now or hereafter
         payable), and aggregate compensation for the fiscal year ended December
         31, 2002 of (A) each director, officer, or other employee of Centre
         whose aggregate compensation for the fiscal year ended December 31,
         2002 exceeded US$25,000 or whose aggregate compensation presently
         exceeds the rate of US$25,000 per annum and (B) all sales agents,
         dealers, or distributors of Centre. Since December 31, 2002, Centre has
         not changed the rate of compensation of any of its directors, officers,
         employees, agents, dealers, or distributors, nor has any Employee
         Benefit Plan or program of Centre been instituted or amended to
         increase benefits thereunder. There is no contract, agreement, plan,
         arrangement, or understanding covering any person that, individually or
         collectively, could give rise to the payment of any amount that would
         not be deductible by Centre by reason of Section 280G of the Code.

         (i) Patents, Trademarks, Et Cetera. Centre does not own or have
pending, and is not licensed or otherwise permitted to use, any material patent,
patent application, trademark, trademark application, service mark, copyright,
copyright application, franchise, trade secret, computer program (in object or
source code or otherwise), or other intangible property or asset (collectively,
"Intangibles"), other than as described in Section C of the Centre Disclosure
Letter. Each Intangible is validly issued and is currently in force and
uncontested in all jurisdictions in which it is used or in which such use is
contemplated. Section C of the Centre Disclosure Letter contains a true and
correct listing of: (i) all Intangibles which are owned (either in whole or in
part), used by, or licensed to Centre or which otherwise relate to the
businesses of Centre, and a description of each such Intangible which identifies
its owner, registrant, or applicant; (ii) all contracts, agreements,
instruments, leases, and licenses and identification of all parties thereto
under which Centre owns or uses any Intangible (whether or not under license
from third parties), together with the identification of the owner, registrant,
or applicant of each such Intangible; (iii) all contracts, agreements,
instruments, leases, and licenses and identification of all parties thereto
under which Centre grants the right to use any Intangible; (iv) all validity,
infringement,

                                      -10-
<PAGE>

right-to-use, or other opinions of counsel (whether in-house or outside) which
concern the validity, infringement, or enforceability of any Intangible owned or
controlled by a party other than Centre which relates to the businesses,
properties, or assets of Centre. Except as specified in Section C of the Centre
Disclosure Letter, to the knowledge of Centre: (v) Centre is the sole and
exclusive owner or licensee of, and (other than those exclusively licensed by
Centre to a third party) has the right to use, all Intangibles; (vi) no
Intangible is subject to any order, judgment, decree, contract, agreement,
instrument, lease, or license restricting the scope of the use thereof; (vii)
during the last five years, Centre has not been charged with, and has not
charged others with, unfair competition, infringement of any Intangible, or
wrongful use of confidential information, trade secrets, or secret processes;
and (viii) Centre is not using any patentable invention, confidential
information, trade secret, or secret process of others. There is no right under
any Intangible necessary to the businesses of Centre as presently conducted or
as it contemplates conducting, except such as are so designated in Section C of
the Centre Disclosure Letter. Except as described in Section C of the Centre
Disclosure Letter, Centre has not infringed, is not infringing, and has not
received notice of infringement in respect of the Intangibles or asserted
Intangibles of others, nor has Centre been advised by counsel or others that it
is infringing or may infringe the Intangibles or asserted Intangibles of others
if any currently contemplated business activity is effectuated. To the knowledge
of Centre, there is no infringement by others of Intangibles of Centre. As far
as Centre can reasonably foresee, there is no Intangible or asserted Intangible
of others that may materially adversely affect the financial condition, results
of operations, businesses, properties, assets, liabilities, or future prospects
of Centre. All material contracts, agreements, instruments, leases, and licenses
pertaining to Intangibles to which Centre is a party, or to which any of its
businesses, properties, or assets are subject, are in compliance in all material
respects with all laws, rules, regulations, orders, judgments, and decrees
binding on Centre or to which any of its businesses, properties, or assets are
subject. Centre has no mark, design, or name used by Centre to identify,
respectively, its products, businesses, or services. Neither any stockholder of
Centre, any director, officer, or employee of Centre, any relative or affiliate
of any stockholder of Centre, any such director, officer, or employee, nor any
other corporation or enterprise in which any stockholder of Centre, any such
director, officer, or employee, or any such relative or affiliate had or now has
a 5% or greater equity or voting or other substantial interest, possesses any
Intangible which relates to the businesses of Centre.

         (j) Questionable Payments. Since the Bankruptcy Termination Date,
neither Centre, nor any director, officer, agent, employee, or other person
associated with, or acting on behalf of, Centre, nor any stockholder of Centre
has, directly or indirectly: used any corporate funds for unlawful
contributions, gifts, entertainment, or other unlawful expenses relating to
political activity; made any unlawful payment to foreign or domestic government
officials or employees or to foreign or domestic political parties or campaigns
from corporate funds; violated any provision of the Foreign Corrupt Practices
Act of 1977, as amended; or made any bribe, rebate, payoff, influence payment,
kickback, or other unlawful payment.

         (k) Authority. Centre has all requisite power and authority to execute,
deliver, and perform this Agreement. All necessary corporate proceedings of
Centre have been duly taken to authorize the execution, delivery, and
performance of this Agreement thereby. This Agreement has been duly authorized,
executed, and delivered by Centre, constitutes the legal, valid, and binding
obligation of Centre, and is enforceable as to Centre in accordance with its
terms. Except

                                      -11-
<PAGE>

as otherwise set forth in this Agreement, no consent, authorization, approval,
order, license, certificate, or permit of or from, or declaration or filing
with, any federal, state, local, or other governmental authority or any court or
other tribunal is required by Centre for the execution, delivery, or performance
of this Agreement by Centre. No consent of any party to any material contract,
agreement, instrument, lease, license, arrangement, or understanding to which
Centre is a party, or to which it or any of its businesses, properties, or
assets are subject, is required for the execution, delivery, or performance of
this Agreement (except such consents referred to in Section D of the Centre
Disclosure Letter); and the execution, delivery, and performance of this
Agreement will not (if the consents referred to in Section D of the Centre
Disclosure Letter are obtained prior to the Closing) violate, result in a breach
of, conflict with, or (with or without the giving of notice or the passage of
time or both) entitle any party to terminate or call a default under, entitle
any party to receive rights or privileges that such party was not entitled to
receive before this Agreement was executed under, or create any obligation on
the part of Centre to which it was not subject immediately before this Agreement
was executed under, any term of any such material contract, agreement,
instrument, lease, license, arrangement, or understanding, or violate or result
in a breach of any term of the certificate of incorporation (or other charter
document) or by-laws of Centre, or (if the provisions of this Agreement are
satisfied) violate, result in a breach of, or conflict with any law, rule,
regulation, order, judgment, or decree binding on Centre or to which any of its
businesses, properties, or assets are subject, which violation or breach would
have a material adverse effect on Centre. Neither Centre, nor any of its
officers, directors, employees, or agents has employed any broker or finder or
incurred any liability for any fee, commission, or other compensation payable by
any person on account of alleged employment as a broker or finder, or alleged
performance of services as a broker or finder, in connection with or as a result
of this Agreement or the transactions contemplated hereby and in connection
herewith.

         (l) Status of Centre Common Stock To Be Issued. Assuming without
investigation that the shares of Genghai Capital Stock outstanding on the
Closing Date are validly authorized, validly issued, fully paid, and
nonassessable, the shares of Centre Common Stock to be issued pursuant to
Section 1.02(a) hereof are validly authorized and, when the such shares of
Centre Common Stock have been duly delivered pursuant to the terms of this
Agreement, such shares of Centre Common Stock will be validly issued, fully
paid, and nonassessable and will not have been issued, owned or held in relation
of any preemptive or similar right of stockholder.

         (m) Insurance. All policies of fire and other insurance against
casualty and other losses and public liability insurance carried by Centre are
described in Section F of the Centre Disclosure Letter (including the risks
covered and limits of such policies) and are in full force and effect. A full
and complete copy of enclosed insurance policy has been, or on or prior to the
Due Diligence Date will be, provided to Genghai and the genghai Shareholders,
and such policies are summarized in Section F of the Centre Disclosure Letter.

         SECTION 2.02 REPRESENTATIONS AND WARRANTIES OF GENGHAI. Genghai hereby
represents and warrants to, and agrees with, Centre:

         (a) Organization and Qualification. Genghai owns no subsidiary or
affiliate corporation or owns any interest in any other enterprise (whether or
not such enterprise is a corporation). Section A of the letter, dated even date
herewith, from Genghai to Centre (the "Genghai Disclosure Letter"), which letter
shall be completed and delivered to Centre on or prior to the Due Diligence
Date, correctly sets forth as to Genghai its place of incorporation, principal
place of business, jurisdictions in which it is qualified to do business, and
the businesses which it presently conducts and which it contemplates conducting.
Genghai is a corporation duly organized, validly existing, and in good standing
under the laws of the People's Republic of China, with all requisite power and
authority, and all necessary consents, authorizations, approvals, orders,
licenses, certificates, and permits of and from, and declarations and filings
with, all federal, state, local, and other governmental authorities and all
courts and other tribunals, to own, lease, license, and use its properties and
assets and to carry on the businesses in which it is now engaged and the
businesses in which it contemplates engaging. Genghai is duly qualified to
transact the businesses in which it is engaged and is in good standing as a
foreign corporation in every jurisdiction in which its ownership, leasing,
licensing, or use of property or assets or the conduct of its businesses makes
such qualification necessary.

         (b) Capitalization. The authorized, registered, outstanding, and paid
up capital stock of Genghai consists of RMB10,000,000 (the "Genghai Capital
Stock"). Each of the outstanding stock of Genghai Capital Stock is validly
authorized, validly issued, fully paid, and nonassessable, has not been issued
and is not owned or held in violation of any preemptive right of stockholders
and by the owner set forth in Section A of the Genghai Disclosure Letter, in
each case free and clear of all liens, security interests, pledges, charges,
encumbrances, stockholders' agreements, and voting trusts. There is no
commitment, plan, or arrangement to issue, and no outstanding option, warrant,
or other right calling for the issuance of, any share of Genghai Capital Stock
or any security or other instrument convertible into, exercisable for, or
exchangeable for Genghai Capital

                                      -14-
<PAGE>

Stock. There is outstanding no security or other instrument convertible into or
exercisable or exchangeable for Genghai Capital Stock.

         (c) Financial Condition. Genghai has delivered, or on or prior to the
Due Diligence Date will deliver, to Centre true and correct copies of the
following: audited balance sheets of Genghai as of December 31, 2002; and
audited statements of income, statements of stockholders' equity, and statements
of cash flows of Genghai for the years ended December 31, 2001 and December 31,
2002. Each such balance sheet presents fairly the financial condition, assets,
liabilities, and stockholders' equity of Genghai as of its date; each such
statement of income and consolidated statement of stockholders' equity presents
fairly the results of operations of Genghai for the period indicated; and each
such statement of cash flows presents fairly the information purported to be
shown therein. The financial statements referred to in this Section 2.02(c) have
been prepared in accordance with generally accepted accounting principles in the
United States consistently applied throughout the periods involved and are in
accordance with the books and records of Genghai. Since December 31, 2002:

                  (i) There has at no time been a material adverse change in the
         financial condition, results of operations, business, properties,
         assets, liabilities, or future prospects of Genghai.

                  (ii) Genghai has not authorized, declared, paid, or effected
         any dividend or liquidating or other distribution in respect of its
         capital stock or any direct or indirect redemption, purchase, or other
         acquisition of any stock of Genghai.

                  (iii) The operations and businesses of Genghai have been
         conducted in all respects only in the ordinary course, except for the
         transactions contemplated hereby and in connection herewith.

                  (iv) There has been no accepted purchase order or quotation,
         arrangement, or understanding for future sale of the products or
         services of Genghai that Genghai expects will not be profitable.

                  (v) Genghai has not suffered an extraordinary loss (whether or
         not covered by insurance) or waived any right of substantial value.

There is no fact known to Genghai which materially adversely affects or in the
future (as far as Genghai can foresee) may materially adversely affect the
financial condition, results of operations, business, properties, assets,
liabilities, or future prospects of Genghai; provided, however, that Genghai
expresses no opinion as to political or economic matters of general
applicability. Genghai has made known, or caused to be made known, to the
accountants or auditors who have prepared, reviewed, or audited the
aforementioned consolidated financial statements all material facts and
circumstances which could affect the preparation, presentation, accuracy or
completeness thereof.

         (d) Tax and Other Liabilities. Genghai does not have any material
liability of any nature, accrued or contingent, including, without limitation,
liabilities for Taxes, and liabilities to customers or suppliers, other than the
following:

                                      -15-
<PAGE>

                  (i) Liabilities for which full provision has been made on the
         consolidated balance sheet and the notes thereto (the "Last Genghai
         Balance Sheet") as of December 31, 2002 (the "Last Genghai Balance
         Sheet Date") referred to in Section 2.02(c); and

                  (ii) Other liabilities arising since the Last Genghai Balance
         Sheet Date and prior to the Closing Date in the ordinary course of
         business (which shall not include liabilities to customers on account
         of defective products or services) or in connection with the
         transactions contemplated hereby or in connection herewith which are
         not inconsistent with the representations and warranties of Genghai or
         any other provision of this Agreement.

Without limiting the generality of the foregoing, the amounts set up as
provisions for Taxes on the Last Genghai Balance Sheet are sufficient for all
accrued and unpaid Taxes of Genghai, whether or not due and payable and whether
or not disputed, under tax laws, as in effect on the Last Genghai Balance Sheet
Date or now in effect, for the period ended on such date and for all fiscal
periods prior thereto. The execution, delivery, and performance of this
Agreement by Genghai will not cause any Taxes to be payable other than by the
stockholders of Genghai or cause any lien, charge, or encumbrance to secure any
Taxes to be created either immediately or upon the nonpayment of any Taxes other
than on the properties or assets of the stockholders of Genghai. The Internal
Revenue Service has audited and settled or the statute of limitations has run
upon all federal income tax returns of Genghai and its predecessors for all
taxable years up to and including the taxable year ended December 31, 2002.
Genghai has filed all federal, state, local, and foreign tax returns required to
be filed by it; has delivered, or on or prior to the Due Diligence Date will
deliver, to Centre a true and correct copy of each such return which was filed
in the past three years since incorporation; has paid (or has established on the
Last Genghai Balance Sheet a reserve for) all Taxes, assessments, and other
governmental charges payable or remittable by it or levied upon it or its
properties, assets, income, or franchises which are due and payable; and has
delivered, or on or prior to the Due Diligence Date will deliver, to Centre a
true and correct copy, of any report as to adjustments received by it from any
taxing authority during the past three years since incorporation and a
statement, as to any litigation, governmental or other proceeding (formal or
informal), or investigation pending, threatened, or in prospect with respect to
any such report or the subject matter of such report.

         (e) Litigation and Claims. Except as set forth in Section G of the
Genghai Disclosure Letter, there is no litigation, arbitration, claim,
governmental or other proceeding (formal or informal), or investigation pending,
threatened, or, to the best of Genghai's knowledge, in prospect (or any basis
therefor known to Genghai), with respect to Genghai or any of its businesses,
properties, or assets. Genghai is not affected by any present or threatened
strike or other labor disturbance nor to the knowledge of Genghai is any union
attempting to represent any employee of Genghai as collective bargaining agent.
Genghai is not in violation of, or in default with respect to, any law, rule,
regulation, order, judgment, or decree which violation or default would have a
material adverse effect upon Genghai; nor is Genghai required to take any action
in order to avoid such violation or default.

                                      -16-

         (f)      Properties.

                  (i) Genghai does not own any legal or equitable interest in
         any real property. Genghai has good title to all other properties and
         assets material to Genghai, used in its business or owned by it (except
         real and other properties and assets as are held pursuant to leases or
         licenses described in Section B or C of the Genghai Disclosure Letter),
         free and clear of all liens, mortgages, security interests, pledges,
         charges, and encumbrances (except such as are listed in Section H of
         the Genghai Disclosure Letter).

                  (ii) All accounts and notes receivable reflected on the Last
         Genghai Balance Sheet, or arising since the Last Genghai Balance Sheet
         Date, have been collected, or are and will be good and collectible, in
         each case at the aggregate recorded amounts thereof without right of
         recourse, defense, deduction, return of goods, counterclaim, offset, or
         set off on the part of the obligor, and, if not collected, can
         reasonably be anticipated to be paid within 180 days of the date
         incurred.

                  (iii) All inventory of raw materials and work in process of
         Genghai is usable, and all inventory of finished goods is good and
         marketable, on a normal basis in the existing product lines of Genghai.
         In no event do such inventories represent more than a 12-month supply
         measured by the volume of sales or use for the year ended December 31,
         2002. All inventory is merchantable and fit for the particular purpose
         for which it is intended.

                  (iv) Attached as Section B of the Genghai Disclosure Letter is
         a true and complete list of the classes of all tangible properties and
         assets owned by Genghai or leased or licensed by Genghai from or to a
         third party (including inventory but not including Intangibles, as
         defined in Section 2.02(i)), and with respect to such properties and
         assets leased or licensed by Genghai from or to a third party, a
         description of such lease or license. All such properties and assets
         (including Intangibles) owned by Genghai are reflected on the Last
         Genghai Balance Sheet (except for acquisitions subsequent to the Last
         Genghai Balance Sheet Date and prior to the Closing Date which are
         either noted in Section B or C of the Genghai Disclosure Letter or are
         approved in writing by Centre). All real and other tangible properties
         and assets owned by Genghai or leased or licensed by Genghai from or to
         a third party are in good and usable condition (reasonable wear and
         tear which is not such as to affect adversely the operation of the
         business of Genghai excepted).

                  (v) To the best of Genghai's knowledge, no real property owned
         by Genghai or leased or licensed by Genghai from or to a third party
         lies in an area which is, or will be, subject to zoning, use, or
         building code restrictions which would prohibit, and, to the best of
         Genghai's knowledge, no state of facts relating to the actions or
         inaction of another person or entity or his or its ownership, leasing,
         or licensing of any real or personal property exists or will exist
         which would prevent, the continued effective ownership, leasing, or
         licensing of such real property in the businesses in which Genghai is
         now engaged or the businesses in which it contemplates engaging.

                                      -17-
<PAGE>
                  (vi) The properties and assets (including Intangibles) owned
         by Genghai (other than those leased or licensed by Genghai to a third
         party) or leased or licensed by Genghai from a third party constitute
         all such properties and assets which are necessary to the business of
         Genghai as presently conducted or as it contemplates conducting.

                  (vii) Genghai has not caused or permitted its businesses
         properties, or assets to be used to generate, manufacture, refine,
         transport, treat, store, handle, dispose of, transfer, produce, or
         process any Hazardous Substance (as such term is defined in this
         Section 2.01(f)(v)) except in compliance with all applicable laws,
         rules, regulations, orders, judgments, and decrees, and has not caused
         or permitted the Release (as such term is defined in this Section
         2.01(f)(v)) of any Hazardous Substance on or off the site of any
         property of Genghai.

         (g) Contracts and Other Instruments. Section D of the Genghai
Disclosure Letter contains a true and correct statement of the information
required to be contained therein regarding material contracts, agreements,
instruments, leases, licenses, arrangements, or understandings with respect to
Genghai. Genghai has furnished, or on or prior to the Due Diligence Date will
furnish, to Centre: (i) the certificate of incorporation and by-laws of Genghai
(or, in each case, the comparable charter documents, if any, under applicable
law) and all amendments thereto, as presently in effect, certified by the
Secretary or an authorized signatory of Genghai and (ii) the following: (A) true
and correct copies of all material contracts, agreements, and instruments
referred to in Section D of the Genghai Disclosure Letter; (B) true and correct
copies of all material leases and licenses referred to in Section B or C of the
Genghai Disclosure Letter; and (C) true and correct written descriptions of all
material supply, distribution, agency, financing, or other arrangements or
understandings referred to in Section D of the Genghai Disclosure Letter. Except
as set forth in Section D of the Genghai Disclosure Letter, Genghai is not party
to any employment agreement with any employee thereof. To the best of Genghai's
knowledge, none of Genghai or any other party to any such contract, agreement,
instrument, lease, or license is now or expects in the future to be in violation
or breach of, or in default with respect to complying with, any term thereof,
and each such material contract, agreement, instrument, lease, or license is in
full force and is (to the best of Genghai's knowledge in the case of third
parties) the legal, valid, and binding obligation of the parties thereto and
(subject to applicable bankruptcy, insolvency, and other laws affecting the
enforceability of creditors' rights generally) is enforceable as to them in
accordance with its terms. Each such material supply, distribution, agency,
financing, or other arrangement or understanding is a valid and continuing
arrangement or understanding; none of Genghai or any other party to any such
arrangement or understanding has given notice of termination or taken any action
inconsistent with the continuance of such arrangement or understanding; and the
execution, delivery, and performance of this Agreement will not prejudice any
such arrangement or understanding in any way. Genghai enjoys peaceful and
undisturbed possession under all leases and licenses under which it is
operating. Genghai is not party to or bound by any contract, agreement,
instrument, lease, license, arrangement, or understanding, or subject to any
charter or other restriction, which has had or, to the best of Genghai's
knowledge, may in the future have a material adverse effect on the financial
condition, results of operations, businesses, properties, assets, liabilities,
or future prospects of Genghai and, following the consummation of the
transactions contemplated hereby, Centre. Genghai has not engaged within the
last five years in, is engaging in, or intends to engage in any transaction
with, or has had within the last five years, now

                                      -18-
<PAGE>

has, or intends to have any contract, agreement, instrument, lease, license,
arrangement, or understanding with, any stockholder of Genghai, any director,
officer, or employee of Genghai (except for employment agreements listed in
Section D of the Genghai Disclosure Letter and employment and compensation
arrangements described in Section E of the Genghai Disclosure Letter), any
relative or affiliate of any stockholder of Genghai, any such director, officer,
or employee, or any other corporation or enterprise in which any stockholder of
Genghai, any such director, officer, or employee, or any such relative or
affiliate then had or now has a 5% or greater equity or voting or other
substantial interest, other than those listed and so specified in Section D of
the Genghai Disclosure Letter. The stock ledgers and stock transfer books and
the minute book records of Genghai relating to all issuances and transfers of
stock by Genghai and all proceedings of the stockholders and the Board of
Directors and committees thereof of Genghai since their respective
incorporations made available to Centre are the original stock ledgers and stock
transfer books and minute book records of Genghai or exact copies thereof.
Genghai is not in violation or breach of, or in default with respect to, any
term of its certificate of incorporation or by-laws (or, in each case, the
comparable charter document, if any, under applicable law).

         (h)      Employees.

                  (i) Genghai does not have, or contribute to, and has not had
         and has not contributed to, any pension, profit-sharing, option, other
         incentive plan, or any other type of Employee Benefit Plan or has any
         obligation to or customary arrangement with employees for bonuses,
         incentive compensation, vacations, severance pay, sick pay, sick leave,
         insurance, service award, relocation, disability, tuition refund, or
         other benefits, whether oral or written.

                  (ii) Section E of the Genghai Disclosure Letter contains a
         true and correct statement of the names, relationship with Genghai,
         present rates of compensation (whether in the form of salary, bonuses,
         commissions, or other supplemental compensation now or hereafter
         payable), and aggregate compensation for the fiscal year ended December
         31, 2002 of (A) each director, officer, or other employee of Genghai
         whose aggregate compensation for the fiscal year ended December 31,
         2002 exceeded US$50,000 or whose aggregate compensation presently
         exceeds the rate of US$50,000 per annum and (B) all sales agents,
         dealers, or distributors of Genghai. Since December 31, 2002, Genghai
         has not changed the rate of compensation of any of its directors,
         officers, employees, agents, dealers, or distributors, nor has any
         Employee Benefit Plan or program of Genghai been instituted or amended
         to increase benefits thereunder.

         (i) Patents, Trademarks, Et Cetera. Genghai does not own or have
pending, and is not licensed or otherwise permitted to use, any Intangibles,
other than as described in Section C of the Genghai Disclosure Letter. Each
Intangible is validly issued and is currently in force and uncontested in all
jurisdictions in which it is used or in which such use is contemplated. Section
C of the Genghai Disclosure Letter contains a true and correct listing of: (i)
all Intangibles which are owned (either in whole or in part), used by, or
licensed to Genghai or which otherwise relate to the businesses of Genghai, and
a description of each such Intangible which identifies its owner, registrant, or
applicant; (ii) all contracts, agreements, instruments, leases, and licenses and
identification of all parties thereto under which Genghai owns or uses any
Intangible (whether or

                                      -19-
<PAGE>

not under license from third parties), together with the identification of the
owner, registrant, or applicant of each such Intangible; (iii) all contracts,
agreements, instruments, leases, and licenses and identification of all parties
thereto under which Genghai grants the right to use any Intangible; and (iv) all
validity, infringement, right-to-use, or other opinions of counsel (whether
in-house or outside) which concern the validity, infringement, or enforceability
of any Intangible owned or controlled by a party other than Genghai which
relates to the businesses, properties, or assets of Genghai. Except as specified
in Section C of the Genghai Disclosure Letter: (v) Genghai is the sole and
exclusive owner or licensee of, and (other than those licensed by Genghai to a
third party) has the right to use, all Intangibles; (vi) no Intangible is
subject to any order, judgment, decree, contract, agreement, instrument, lease,
or license restricting the scope of the use thereof; (vii) during the last five
years, Genghai has not been charged with, and has not charged others with,
unfair competition, infringement of any Intangible, or wrongful use of
confidential information, trade secrets, or secret processes; and (viii) Genghai
is not using any patentable invention, confidential information, trade secret,
or secret process of others. There is no right under any Intangible necessary to
the businesses of Genghai as presently conducted or as it contemplates
conducting, except such as are so designated in Section C of the Genghai
Disclosure Letter. Genghai has not infringed, is not infringing, and has not
received notice of infringement in respect of the Intangibles or asserted
Intangibles of others, nor has Genghai been advised by counsel or others that it
is infringing or may infringe the Intangibles or asserted Intangibles of others
if any currently contemplated business activity is effectuated. To the knowledge
of Genghai, there is no infringement by others of Intangibles of Genghai. As far
as Genghai can foresee, there is no Intangible or asserted Intangible of others
that may materially adversely affect the financial condition, results of
operations, businesses, properties, assets, liabilities, or future prospects of
Genghai. All contracts, agreements, instruments, leases, and licenses pertaining
to Intangibles to which Genghai is a party, or to which any of its businesses,
properties, or assets are subject, are in compliance with all laws, rules,
regulations, orders, judgments, and decrees binding on Genghai or to which any

date hereof and through the Release Time, unless Centre will otherwise approve
in writing, which approval will not be unreasonably withheld, as follows:

         (a) Such Genghai Shareholder will use best efforts to cause Genghai to
perform each covenant thereof set forth herein on a timely basis.

         (b) Until the earlier of the Release Time, such Genghai Shareholder
shall take no action the result of which shall be to cause Genghai to make any
amendment in the certificate of incorporation or by-laws (or, in each case, the
comparable charter documents, if any, under applicable law) thereof.

         (c) Before such Genghai Shareholder releases any information concerning
this Agreement or any of the transactions contemplated by this Agreement which
is intended for, or may result in, public dissemination thereof, such Genghai
Shareholder shall cooperate with Centre, shall furnish drafts of all documents
or proposed oral statements to Centre for comment, and shall not release any
such information without the written consent of Centre, which consent shall not
be unreasonably withheld. Nothing contained herein shall prevent such Genghai
Shareholder from releasing any information if required to do so by law.

         (d) Such Genghai Shareholder shall furnish, or cause to be furnished,
for inclusion in the Periodic Reports to be filed pursuant to the Exchange Act
in connection with the transactions contemplated by this Agreement, or for
inclusion in Centre's filings under state "blue-sky,"

securities, or take-over laws, such information about Genghai or the Genghai
Shareholders as may be required or as may be reasonably requested by Centre, and
shall continue to furnish or cause to be furnished such information as is
necessary to keep such information correct and complete in all material respect
until the Release Time. Such Genghai Shareholder represents and warrants that
the information in writing that it has furnished to date regarding himself or
herself, taken as a whole, does not now, and will not at any time prior to the
Release Time, (i) contain an untrue statement of a material fact or (ii) omit to
state a material fact required to be stated therein or necessary to make the
statements therein not false or misleading.

they have carefully examined the financial statements of Genghai delivered to
Centre pursuant hereto, as well as the Genghai Disclosure Letter, and, to the
best of their knowledge, (i) neither such financial statements, nor the Genghai
Disclosure Letter (A) contains an untrue statement of a material fact or (B)
omits to state a material fact required to be stated therein or necessary to
make the statements therein not false or misleading, provided in each case that
such untrue statement or omission relates to information furnished by or on
behalf of, or pertaining to, Genghai or any Genghai security holder, (ii) since

instrument, lease, or license regarding Genghai required to be included in the
Genghai Disclosure Letter.

enforced, or deemed applicable to the transactions contemplated by this
Agreement by any federal, state, local, or other governmental authority or by
any court or other tribunal, including the entry of a preliminary or permanent
