                                   SECTION 2

                                      -11-
<PAGE>

dollars, subject to reduction pursuant to Section 6.1(e). The Purchase Price
shall be paid as follows:

     (a) At the Closing, eight hundred thousand and no/100 ($800,000.00) dollars
shall be delivered to a to be mutually agreed upon bank, as escrow agent (the

     (c) The balance of the Purchase Price shall be delivered to Seller at the

Date.

     2.3 Inventory.

     Seller shall commence a physical inventory of all raw materials, work in
process and finished goods of each Corporation, sufficiently in advance of the
Closing Date so as to assure that such inventory is completed by the close of
business on the Business Day immediately preceding the Closing Date and a
statement of closing inventory, calculating such inventory consistent with
practices and methodologies used in preparing the Financial Statements and past
practices of the Corporations, is available on the Closing Date. Such inventory
shall be conducted under the auspices of the Closing Accountants and observed by
representatives of Seller and Buyer to determine quantities and valuations. As
soon as


                                      -12-
<PAGE>

reasonably possible after the Closing Date, the Closing Accountants shall
prepare a report on the results of such inventory and provide such report to
Seller and Buyer.

     2.4 Payment of Taxes. Seller shall pay, at the Closing or, if due
thereafter, promptly when due, all stock transfer taxes, if any, payable in
connection with its transfer of the Purchased Stock and any gains or income
taxes resulting from Seller's receipt of the Purchase Price. The parties hereto
agree that the unaudited and combined balance sheet referred to in Section
3.2(1)(15) shall take into account and reflect any adjustment to the inventory
of the Corporations resulting from such physical inventory taken, and the
statement prepared in respect thereof, pursuant to Section 2.3.

                                   SECTION 3

                              CLOSING TRANSACTIONS

     3.1 Closing Date. (a) The closing of the transactions provided for herein
(the "Closing") shall take place at the offices of Stoel Rives LLP, 201 South
Main Street, Suite 1100, Salt Lake City, Utah, at 10:00 A.M. local time on
November 30, 2001, except that:

          (1) If all of the conditions set forth in Section 6.1 have not been
     satisfied by November 30, 2001, Buyer may, at its option:

               (A) postpone the Closing upon notice to Seller until the earlier
          of January 7, 2002, or the tenth day following the date on which such
          conditions have been satisfied, except to the extent that any such
          condition can only be satisfied at the Closing; or

               (B) terminate this Agreement upon notice to Seller provided that
          Buyer is not then in material default of any of its obligations
          hereunder.

          (2) If the Closing has been postponed pursuant to clause (1)(A) above,
     and if all of the conditions set forth in Section 6.1 have not been

                                      -13-
<PAGE>

     Buyer may terminate this Agreement upon notice to Seller provided that
     Buyer is not then in material default of any of its obligations hereunder,
     unless:

               (A) within five Business Days of the giving of Buyer's notice,
          Seller agrees to indemnify and hold harmless Buyer from any Damages
          arising as a result of the failure of such conditions to have been
          satisfied (such indemnification to be in accordance with the
          provisions of Section 7); and

               (B) at the Closing, Seller provides adequate security for such
          indemnification by either delivering to Buyer a performance bond or
          irrevocable standby letter of credit (in either case in form
          reasonably satisfactory to Buyer) or increasing that portion of the
          Purchase Price payable to the Escrow Agent pursuant to Section 2.2(a)
          by a good faith determination of the amount of Damages which could
          reasonably be expected to result from the failure of such condition to
          be satisfied.

          (3) If all of the conditions set forth in Section 6.1 have not been
     satisfied by January 7, 2002, and this Agreement has not been terminated
     and the Closing has not taken place by such date, then Seller or Buyer may
     terminate this Agreement, it being understood that any such termination
     shall not serve to limit either party's remedies arising from any breach of
     this Agreement at law, in equity or otherwise (except that neither party
     shall be entitled to recover lost profits or other special damages
     resulting from such breach). If the Closing has not taken place by the date
     for Closing determined in accordance with this Section 3.1 (the "Closing

     this Agreement upon notice to the other party, provided that the party
     giving such notice is not then in material default of any of its
     obligations hereunder which default is the basis of the failure of any of
     the conditions set


                                      -14-

     forth in Section 6 to be satisfied by the Closing Date. The Closing shall

specified increase or decrease in a market index), (ii) a declaration of a
banking moratorium or any suspension of payments in respect of banks in the
United States or Israel, (iii) any limitation (whether or not mandatory) on the
extension of credit by banks or other lending institutions in the United States
or Israel, (iv) the commencement of a war involving the United States or Israel,
or (v) in the case of any of the foregoing existing at the time of the execution
of this Agreement, a material acceleration or a material worsening thereof,
Buyer may postpone the Closing until a date that is five (5) Business Days after

Corporation:

          (1) has all requisite corporate power and governmental licenses,
     authorizations, consents and approvals necessary to own its assets and
     carry on its business as now being conducted; and

          (2) is qualified to do business in all jurisdictions in which the
     nature of the business conducted by it makes such qualification necessary
     and where failure to do so would have a Material Adverse Effect.

     (b) The authorized capital stock of each Corporation is as set forth on
Schedule 4.1(b). The Purchased Stock to be conveyed to Buyer pursuant to Section

the Purchased Stock to be conveyed to Buyer pursuant to Section 2.1(a) shall be
conveyed to Buyer free and clear of all liens, claims and encumbrances of any
kind or nature whatsoever.

     (c) The Corporations have no Subsidiaries.

     (d) Except as set forth on Schedule 4.1(d), neither the execution and

assets is subject; (2) conflict with or result in a breach of, or constitute a
default under, the Certificate or Articles of Incorporation or By-laws of any of
the Corporations, (3) constitute or result in (with notice, lapse of time or
both) a breach by any of the Corporations or any other Person of any term,
condition or provision of, or constitute a default by any of the Corporations or
any other Person under, or result in the creation of any lien, charge or
encumbrance upon any property or assets of any of the Corporations or Seller

or Seller is a party or by which any of their respective property or assets is
bound, (4) not result in the loss of any license, certificate, legal privilege
or legal right which is enjoyed or possessed by any of the Corporations, (5) not

or assets, before any court or arbitrator or by or before any governmental
commission, bureau or other regulatory authority. To the best of


                                      -21-
<PAGE>

Seller's knowledge, except as otherwise described on Schedule 4.1(e), none of
the Corporations is in default under or in violation of any law, rule,
regulation, order, writ, injunction or decree of any court, arbitrator,
governmental commission, bureau or other regulatory authority. Except as set
forth on Schedule 4.1(e), to the best of Seller's knowledge, there are no claims
against any of the Corporations not covered by insurance (subject to deductibles
or co-payments provided for in the insurance policies referred to on Schedule
4.1(p)), alleging that any product sold by such Corporation (other than products
which are the subject of recalls described on Schedule 4.1(e)) was not sold free
from defects in materials and workmanship. To the best of Seller's knowledge,
the finished goods included in the inventory of each Corporation on the Closing
Date will be free of defects in materials and workmanship.

     (f) Each Corporation has good and indefeasible title to its properties and
assets, free and clear of all liens, claims, charges and encumbrances of any

          (2) Except as otherwise described on Schedule 4.1(g), there are no
     lawsuits, investigations, reviews, audits or other proceedings pending or,
     to the best of Seller's knowledge, threatened against any of the

     successor, by contract, or otherwise.

          (4) Except as set forth on Schedule 4.1(g), none of the Corporations

     consequences of any sale of the Purchased Stock by Buyer after the Closing
     Date.

          (5) None of the Corporations has ever made or been required to make an
     election under Section 338 of the Code (except as required by this
     Agreement). None of the


                                      -23-
<PAGE>

     Corporations has ever been included in a consolidated, combined or unitary
     Tax return. The Corporations are not and have never been a party to any Tax
     sharing or Tax allocation agreement, arrangement or understanding. Except
     as set forth in Schedule 4.1(g), no taxing authority has ever asserted that
     the Corporations should file a Tax return in a jurisdiction where it does
     not file. The Corporations do not have outstanding any power of attorney,
     closing agreement or other instruments authorizing another person to act on
     their behalf in connection with any Tax, Tax return, proceeding relating to
     any Tax or Tax return or any other Tax matter.

          (6) None of the Corporations will be liable for any Tax under Code

Incorporation and the By-Laws (each as amended to date) of each Corporation, and
each Lease, consent, permit, license, instrument and agreement listed on
Schedule 4.1(h) have heretofore been delivered to Buyer and to the best of
Seller's knowledge all of the foregoing are in full force and effect. None of
the Corporations has received a notice to the effect that, and, to the best of
Seller's knowledge, none of the Corporations is in default in the payment or
performance or observance of any contract, agreement or other instrument to
which it is a party or by which it or any of its respective assets is bound,
which individually or


                                      -24-
<PAGE>

together with all other such defaults could have a Material Adverse Effect.
Except to the extent indicated on Schedule 4.1(h), none of the Corporations is a
party to, nor are any of the Corporations bound by, any non-competition

otherwise in such Corporation's employment conditions or practices with respect
to employees or former employees for which Buyer or the Corporations will have
any liability following the Closing.

equipment included in such properties and assets have been properly maintained
and are in good working condition, reasonable wear and tear excepted.

     included in their respective properties and assets, except in the ordinary
     course of business and, unless such assets were obsolete or unnecessary and
     the proceeds of such sale, assignment or transfer of such obsolete or
     unnecessary properties or assets were used to acquire assets of like use
     and substantially the same value, or cancel any debts or claims incurred in
     the ordinary course of business of such Corporation;

payment of any royalties, or validly owns, beneficially and of record, and holds
in each jurisdiction in which such Corporation's products are currently, or have
been, sold or in which sales are currently being solicited, sufficient right,
title and interest (although the same may not be exclusive) in and to such
Intellectual Property and Know-how, free and clear of any lien, claim, charge or
encumbrance. The operation of the business of each Corporation after the Closing
in the manner currently conducted by such Corporation will not infringe any
Intellectual Property or any other rights of any nature whatsoever of others.
Except as set forth on Schedule 4.1(l), no action, suit,


                                      -27-

threatened, nor to the best of Seller's knowledge has any claim been asserted or
threatened (by or against any of the Corporations or any third party), which
involves any Intellectual Property or Know-how of or used by any of the
Corporations nor, to the best of Seller's knowledge, does any state of facts
exist under which any such action, suit, arbitration, proceeding or
investigation might be based. Except as set forth on Schedule 4.1(l), none of
the Corporations is subject to any judgment, order, writ, injunction or decree
of any court or any federal, state, local or other governmental department,
commission, board, bureau, agency or instrumentality, domestic or foreign, or

instruments and information required to be filed by it pursuant to applicable
rules and regulations or requests of every regulatory body having jurisdiction
over such Corporation's respective assets and properties except where the
failure to so file would not have a Material Adverse Effect.

any entity which is under common control with any of the Corporations within the
meaning of Section 4001 of ERISA or which is part of a group which includes any

     any, with respect to each Plan required under ERISA; (D) the most recent
     favorable determination letter from the Internal Revenue Service, if
     applicable, with respect to each Plan; and (E) all material communications,
     if any, to any current or former employee, officer, independent contractor,
     agent or consultant of any of the Corporations relating to each Plan.

          (3) Each Plan that is intended to be qualified under the Code has
     received a determination letter from the Internal Revenue Service to the
     effect that such Plan and related trust are so qualified and are exempt
     from federal income taxes under Sections 401(a) and 501(a) of the Code, and
     no such determination letter has been revoked, nor to the best of Seller's
     knowledge, has revocation been threatened. To the best of Seller's
     knowledge, nothing has occurred or is expected to occur that would
     adversely affect the qualified status of any Plan or related trust
     subsequent to the issuance of such determination letter.

          (4) Each of the Corporations, and any Employer Group of which any of
     them is or has been a member, has performed in all material respects all
     obligations required to be performed by it under each Plan, and each Plan
     has been established and maintained in all material respects in accordance
     with its terms and in compliance with all applicable laws, statutes,
     orders, rules and regulations, including but not limited to ERISA and the
     Code. No Plan is a defined benefit plan within the meaning of Section 3(35)
     of ERISA; and none of the Corporations has any liability with respect to
     any such Plan as a result of having been treated as


                                      -29-
<PAGE>

     part of a "single employer" within the meaning of Section 414(b), (c), (m),
     (n) and (o) of the Code, nor to the best of Seller's knowledge is there any
     basis for such liability being imposed. There are no investigations,
     claims, suits, or proceedings pending, or, to the best of Seller's
     knowledge, threatened or anticipated (other than routine claims for
     benefits) against any Plan or the assets of any Plan, and to the best of
     Seller's knowledge, there are no facts that could give rise to any material
     liability in the event of any such investigation, claim, suit or
     proceeding. Except as required by collective bargaining agreements listed
     on Schedule 4.1(i) and the laws, rules and regulations applicable thereto,
     each Plan can be amended, terminated, or otherwise discontinued after the
     Closing in accordance with its terms, without liability to Buyer, any of
     the Corporations or any of their Affiliates. All premiums required by any
     Plan have been paid thereunder; all outstanding indebtedness for services
     performed or accrued vacation, holiday pay, earned commissions, accrued
     bonuses or other benefits owed to any current or former employee, officer,
     independent contractor, agent or consultant of any of the Corporations have
     been paid when due or accrued on the books of such Person; all
     contributions due to, and payments from, the Plans that may have been
     required to be made have been made. No "prohibited transaction" within the
     meaning of Section 4975 of the Code or Section 406 of ERISA has occurred
     with respect to any Plan; no action or failure to act with respect to any
     Plan could subject Buyer, any of the Corporations or any of their
     respective Affiliates or any Plan to any material tax, penalty or other
     liability, for breach of fiduciary duty or otherwise, under ERISA or any
     other applicable law, whether by way of indemnity or otherwise.

          (5) Each "group health plan" within the meaning of Section 4980B(g)(2)
     of the Code maintained by any of the Corporations or any entity with which
     any of them is considered a "single employer" within the meaning of Section
     414(b), (c), (m), (n) and


                                      -30-
<PAGE>

     (o) of the Code, has been administered in good faith in compliance with the
     continuation coverage requirements contained in the Consolidated Omnibus
     Budget Reconciliation Act of 1985, as amended, as set forth at Section
     4980B of the Code and any regulations promulgated or proposed thereunder
     (if such proposed regulations constitute substantial authority within the
     meaning of Section 6662 of the Code and any regulations promulgated
     thereunder).

          (6) Except as specifically set forth on Schedule 4.1(n), (A) the
     execution and delivery of, and performance of the transactions contemplated
     by, this Agreement will not (either alone or upon the occurrence of any
     additional or subsequent events) constitute an event under any trust or
     individual agreement that will or may result in any payment (whether of
     severance pay or otherwise), acceleration, vesting, distribution or
     increase in or obligation to fund benefits with respect to any employee of
     any of the Corporations; and (B) no payment or benefit which will or may be
     made by any of the Corporations or any of their respective Affiliates with
     respect to any employee will be characterized as an "excess parachute
     payment," within the meaning of Section 280G(b)(1) of the Code. No material
     promises or commitments have been made with respect to any Plan other than
     in accordance with a reasonable interpretation of the terms of such Plan.
     There is no plan or commitment, whether legally binding or not, to
     establish or enter into any new Plan or to modify (other than by way of
     termination) any Plan (except to the extent required by law); nor has any
     intention or commitment to do any of the foregoing been communicated to any
     employee of any of the Corporations.

          (7) None of (A) the Corporations or (B) any of their respective
     Affiliates maintains or contributes to any Plan which provides, or has any
     liability to provide, life insurance, medical or other welfare plan
     benefits (within the meaning of Section 3(1) of ERISA)


                                      -31-
<PAGE>

     to any employee upon his or her retirement or termination of employment,
     except as may be required by law.

          (8) At no time has any of the Corporations or any Employer Group of
     which any of them is or has been a member been required to contribute to,
     or incurred any withdrawal liability (within the meaning of Section 4201 of
     ERISA) to, any multiemployer plan as defined in Section 3(37) of ERISA.

     Corporations (and, to the extent known by Seller, their respective

     violation of Environmental Laws which would, individually or in the
     aggregate, have a Material Adverse Effect are set forth on Schedule 4.1(o).

     continues to possess all permits, licenses, approvals or other
     authorizations under the Environmental Laws relating to the operation of
     the business of each of such Corporation as now conducted the failure of
     which to obtain or continue to possess would, individually or in the
     aggregate, have a Material Adverse Effect.

          (3) Except as set forth on Schedule 4.1(o), there are no past or
     present events, conditions, circumstances, activities, practices,
     incidents, actions or plans (A) which may prevent continued compliance by
     any of the Corporations with the Environmental Laws or which may give rise
     to any criminal or civil liability relating to the respective businesses of
     any such Corporation as now conducted under the Environmental Laws, and (B)
     which would, individually or in the aggregate, have a Material Adverse
     Effect.

insured by reputable insurance companies against loss or damage by fire and
other risks to the extent and in the manner customary for companies engaged in
similar businesses and no other insurance is in Seller's reasonable business
judgment necessary to the conduct of the businesses of the Corporations as

riot, war or other hostility or terrorist act, storm, condemnation, act of God
or other public force, or otherwise.

and warranty of Seller inaccurate in any material respect as of the date hereof
or as of the Closing Date.

     (m) None of the Corporations shall make any payments to, or enter into any
transactions with, any of their respective Affiliates or Seller (other than

Sheet as accrued current liabilities of such Corporation, or (2) the payment or
transaction is required to settle a balance with Affiliates or Seller as of the
Closing Date.

     (n) Without Buyer's prior written consent, which consent shall not be
unreasonably withheld, conditioned or delayed, none of the Corporations shall

would subject any of them to injunctive or other equitable relief or give rise
to any financial obligation.

     (o) Seller will not revoke the election of any of the Corporations to be
taxed as an S corporation within the meaning of Code Sections 1361 and 1362.
Seller and the Corporations will not take or allow any action (other than the

termination of the status as any of the Corporations as a validly electing S
corporation within the meaning of Code Sections 1361 and 1362.

     (p) Seller shall prepare or cause to be prepared and file or cause to be
filed all Tax returns for each of the Corporations for all periods ending on or

which are to be filed after the Closing Date. Seller shall permit Buyer to
review and comment on each such Tax return described in the preceding sentence
prior to filing and shall make such revisions to such Tax returns as are
reasonably requested by Buyer. To the extent permitted by applicable law, Seller
shall include any income, gain, loss, deduction or other tax items for such
periods on its Tax returns in a manner consistent with the Schedule K-1s
furnished by the Corporations to Seller for such periods. From and after the
Closing, Buyer shall permit Seller and Seller's professional advisors access to
the books and records of the Corporations to the extent reasonably necessary or
helpful for Seller to prepare Tax returns for each of the Corporations for all
periods ending on or prior to the Closing Date which are to be filed after the
Closing Date. Buyer shall cooperate fully, and shall cause the Corporations to
cooperate fully, as and to the extent reasonably requested by Seller, in
connection with the preparation by Seller of such Tax returns to be prepared by
Seller. Such cooperation shall include, but not be limited to, the retention of
records and information reasonably relevant to the preparation, filing and
submission of such Tax returns by Seller.

     5.2 Third Party Consents.

     (a) The parties shall cooperate fully with one another in obtaining any
necessary consents and approvals required for the consummation of the

     (b) Neither party hereto shall take any intentional action or steps which
would prejudice or jeopardize the obtaining of any necessary consent to the
transactions contemplated by this Agreement.

make any settlement of any claim if as a result thereof the Indemnified Party
would become subject to injunctive or other equitable relief or the Tax status,
business or financial condition of the Indemnified Party would be adversely
affected. Without the prior written consent of the Indemnifying Party, which
consent shall not be unreasonably withheld, conditioned or delayed, the

contemplated hereby. Such right and remedy shall be in addition to, and not in
lieu of, any other rights and remedies available to Buyer at law or in equity.

     8.3 Assignment. No party hereto may assign or transfer its rights or
obligations arising under this Agreement, without the written consent of the
other party hereto, which consent may be withheld in the sole and absolute
discretion of the party asked to consent; provided, however, that Buyer may
assign its rights hereunder in whole or in part to any


                                      -52-

Affiliate, or any partnership in which any of its Affiliates is a general

assignor of its obligations hereunder) so long as such assignment shall not
serve to delay the Closing.

respective Affiliates as concerns the subject matter of this Agreement. This

any person or entity other than the parties hereto and their successors or

     8.7 Captions. Captions and descriptive headings are for convenience of
reference only and shall not control or affect the meaning or construction of
any provisions of this Agreement.

counterpart copies, each of which shall be deemed an original, but which

communications under the Utah Rules of Professional Conduct and Utah law
(collectively, the "Transaction Communications"). Subsequent to the consummation
of the transactions contemplated by this Agreement, the confidential nature of
the Transaction Communications shall be preserved and, therefore, the

     8.11 Severability. Any term or provision of this Agreement which is invalid
or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms or provisions of this
Agreement (unless a failure of consideration would result thereby) or affecting
the validity or enforceability of any of the terms or provisions of this
Agreement in any other jurisdiction.

     8.12 Governing Law. The laws of the State of Delaware, without reference to
Delaware choice of law or conflicts of law provisions, shall govern all other
