                of the breach specifying in detail the facts and circumstances
                constituting the breach.




                (c) "Disability" means the inability of Erickson to perform the

                (d) "Good Reason" means the occurrence of all of the following:

                        (i) the Company materially breaches this Agreement or

                duties other than those of the interim President and Chief
                Executive Officer, except as specifically set out in paragraph

                facts and circumstances constituting the breach within ten (10)
                days following the occurrence of the breach;

                        (iii) the Company fails to remedy the breach within ten
                (10) days following Erickson's written notice of the breach; and

                        (iv) Erickson terminates the engagement and this
                Agreement within ten (10) days following the Company's failure

                (a) Engagement. Erickson shall be deemed an employee of the
        Company as of August 12, 2002. Beginning on the date that the Company
        receives the resignation of Mark B. Chandler, Ph.D., Erickson shall be
        the interim President and Chief Executive Officer of the Company,
        subject to the terms and conditions hereof, and shall perform the duties
        of that position. Notwithstanding any other provision hereof, in the
        event the Company appoints another person as President and Chief
        Executive Officer during the Term (defined in Section 4 hereof), and
        removes Erickson as interim President and Chief Executive Officer, the
        Board of Directors of the Company may cause Erickson to perform other
        management or management advisory duties to the Company which the Board
        of Directors may reasonably request for the remainder of the Term; and
        in the event the Company appoints another person as interim President
        and Chief Executive Officer during the Term, then (i) the Company shall
        be obligated to perform all of its obligations to Erickson under this
        Agreement unless the Company has terminated Erickson for cause; and (ii)
        Erickson may immediately cease rendering any services for the Company.

                (b) Benefits. Erickson shall receive substantially the same
        benefits as other executives of the Company, except that Erickson
        intends to opt out of the group medical plan the Company offers to its
        executives.




                                       2


        3. Compensation.

                (a) Cash Compensation. For the month of August 2002, the Company
        shall pay to Erickson $35,984.85 for Erickson's services to the Company.
        Thereafter, the Company shall pay to Erickson $41,667 per month for
        Erickson's services hereunder. The Company shall pay the monthly cash
        compensation in substantially equal installments after the services are
        performed in accordance with the payroll policies of the Company. For
        any partial month during the term hereof, the Company shall pay Erickson
        after the services are performed cash compensation on a pro rata basis
        as set forth above.

                        (i) The Company will also pay Erickson $414.12 per month
                so that Erickson can continue to pay for coverage under his
                current medical plan.

                (b) Stock Options. Erickson shall be granted options to purchase
        an aggregate of 40,000 shares of the Company's Common Stock. The options
        shall vest and become immediately exercisable in accordance with the
        following schedule:




                          DATE                             NUMBER OF SHARES

        The exercise price for each option will be the closing price of the
        Company's Common Stock on August 12, 2002. The option grants will be
        subject to the terms and conditions applicable to options granted under
        the Company's 2000 Long-Term Incentive Plan (the "Plan") and shall
        remain exercisable for a period of ten (10) years following the date of
        grant. Upon termination of Erickson's employment (i) by the Company for
        Cause, or by Employee, without Good Reason, no further options shall
        vest after the date of termination, but all options vested prior to the
        date of termination shall remain vested and exercisable for a period of
        ten (10) years following the date of grant, and (ii) for any other
        reason by the Company or Erickson, all options shall automatically vest
        as of the date of termination and be exercisable for a period of ten
        (10) years following the date of grant. Erickson will be mailed a
        statement detailing his vested options by the 15th day following the
        close of each monthly vesting period. Erickson and the Company shall
        enter into a Stock Option Award Agreement that, notwithstanding the
        terms of the Plan, contains terms consistent with those set forth above.

                (c) Expenses. Erickson shall be entitled to be reimbursed in
        accordance with the policies of the Company, as adopted and amended from
        time to time, for all reasonable and necessary expenses incurred by
        Erickson in connection with the performance of Erickson's duties of
        employment hereunder. Such expense




                                       3


        reimbursement to Erickson will include, without limitation:

                        (i) Erickson's reasonable business travel expenses
                between Dallas, Texas and Austin, Texas incurred in connection
                with the performance of his duties hereunder, including airfare,
                automobile expenses, lodging, and meals while he is performing
                services hereunder in Austin; and

                        (ii) Erickson's cell phone charges, fees and expenses
                incurred in connection with his employment hereunder.

        4. Term, Termination and Termination Payments.

                (a) Term. Unless sooner terminated pursuant to Section 4(b)
        hereof or extended by written agreement of the parties, the term of this
        Agreement shall commence as of August 12, 2002 and will end February 28,
        2003 (the "Term").

                (b) Termination. This Agreement and the engagement of Erickson
        by the Company hereunder may only be terminated: (i) by expiration of
        the term set forth in Section 4(a) hereof; (ii) by mutual agreement of
        the parties; (ii) by the Company without Cause; (iii) by Erickson for
        Good Reason; (iv) by the Company or Erickson due to the Disability of
        Erickson; or (v) by the Company for Cause. This Agreement shall also
        terminate immediately upon the death of Erickson. Notice of termination

        specify the basis for termination and the effective date of termination.
        Notice of termination for Cause by the Company shall specify the basis
        for termination for Cause. Except as provided in Section 4(c) and except
        as provided under the terms of the stock option agreements referred to
        in Section 3(b), Erickson shall not be entitled to any payments on

        compensation pursuant to Section 3(a) accrued up to the date of
        termination and expenses required to be reimbursed pursuant to Section
        3(c) hereof.

                (c) Termination by the Company without Cause or by Erickson for

        without Cause or by Erickson for Good Reason, the Company will continue
        to pay Erickson the remainder of the cash compensation pursuant to
        Section 3(a) hereof for the remainder of the Term (determined without
        regard to the Company's premature termination thereof) on the same
        schedule as if Erickson had continued to perform services for such
        period and the stock options described in Section 3(b) shall be granted,
        vest and remain exercisable pursuant to the terms of the Agreement.

                (d) Survival. The covenants of Erickson in Section 5 hereof
        shall survive the termination of this Agreement and shall not be
        extinguished thereby.




                                       4




        5. Covenant Not to Compete; Confidentiality and Trade Secrets; Ownership
           of Intellectual Property.

                (a) Covenant Not to Compete. Erickson shall not, during the Term
        of this Agreement and for a period of one (1) year immediately following
        the termination of this Agreement, or any extension thereof, for any
        reason, either directly or indirectly: (a) call on, solicit, or take
        away any of the Company's customers or potential customers about whom
        Erickson became aware as a result of Erickson's services to the Company,
        either for Erickson or for any other person or entity; or (b) solicit or
        take away or attempt to solicit or take away any of the Company's
        employees or contractors for Erickson or for any other person or entity.

                (b) Confidentiality and Trade Secrets. Erickson acknowledges and
        agrees that he has and/or will, during the Term of this Agreement,
        become privy to important proprietary, confidential business information
        and trade secrets that are the exclusive property of the Company. This
        information includes, without limitation, the methodology and processes
        of the chemical, hardware, software and firmware components of Luminex's
        xMAP(TM) technology that combines single- or variably-sized microspheres
        with differential fluorescent labeling to generate information useful
        for a variety of applications, business plans, marketing concepts,
        designs, proposals, product information, financial information,
        technology and costs, pricing information, customer lists, and key
        accounts, including their credit information and product wants and needs
        (the "Confidential Information"). This Confidential Information derives
        independent economic value, both actual and potential, from not being
        generally known to the public or to other persons who can obtain
        economic value from its disclosure and use. As the Company has always
        held the Confidential Information as proprietary, confidential trade
        secret information and has taken steps to insure that the Confidential
        Information is not disclosed outside of the Company, the Confidential
        Information constitutes "trade secrets" under the Uniform Trade Secrets
        Act and Texas state law. In light of the foregoing, Erickson therefore
        agrees that he will not at any time, now or in the future, share,
        disseminate, disclose, discuss or use the Confidential Information or
        Trade Secrets in any way.

                (c) Return of Company Property. Upon termination of this
        Agreement for any reason, as a prior condition to receiving any final
        compensation hereunder (including any payments pursuant to Section 4
        hereof), Erickson will promptly deliver to the Company all property
        belonging to the Company, including, without limitation, all
        Confidential Information and Trade Secrets (and all embodiments thereof)
        then in Erickson's custody, control or possession.

                (d) Survival. The covenants set forth herein will apply on and
        after the Effective Date hereof to any Confidential Information and
        Trade Secrets disclosed by the Company or developed by Erickson prior to
        or after the Effective Date hereof. The covenants restricting the use of
        Confidential Information will continue and be maintained by Erickson for
        a period of two years following the termination of this Agreement. The




                                       5



        covenants restricting the use of Trade Secrets will continue and be
        maintained by Erickson following termination of this Agreement for so
        long as permitted by Texas law.

                (e) Ownership of Intellectual Property. Erickson hereby
        acknowledges and agrees that any and all copyrightable works authored by
        him in connection with the performance of services, alone or with
        others, during the Term of this Agreement, shall be deemed to have been
        specially ordered or commissioned for use as either a contribution to a
        collective work, as a translation, as a supplementary work, as a
        compilation, or as an instructional text and, as such, shall be deemed
        to be "works for hire" under the United States copyright laws from the
        inception of creation or such works. In the event that any such works
        shall be deemed by a court of competent jurisdiction not to be a "work
        made for hire," this Agreement shall operate as an irrevocable
        assignment by Erickson to the Company of all right, title and interest
        in and to such works, including without limitation, all worldwide
        copyright interests therein, in perpetuity. The fact that such
        copyrightable works are created by Erickson outside of the Company's
        facilities or other than during Erickson's working hours with the
        Company, shall not diminish the Company's rights with respect to such
        works which otherwise fall within this subsection. Erickson agrees to
        execute and deliver to the Company such further instruments or documents
        as may be requested by the Company in order to effectuate the purposes
        of this subsection.

                (f) Indemnification and Director and Officer Liability
        Insurance. The Company shall indemnify Erickson and Erickson's actions
        as interim President and Chief Executive Officer or in any other
        capacity in which he may render services to the Company to the maximum
        extent permitted by the laws of the state of incorporation of the
        Company. The Company will not, during the Term of this Agreement, amend
        its certificate of incorporation or by-laws so as to limit in any way
        the Company's indemnification or expense advancement obligations
        contained therein on the Effective Date. At all times during the term of
        this Agreement, the Company will cover Erickson, and name him as an
        insured to the extent necessary as a condition of coverage, under any
        director and officer liability policy it may maintain, in his capacity
        as the interim President and Chief Executive Officer or in any other
        capacity in which he may render services to the company.

        6. Contracts or Other Agreements with Former Employer or Business.

                Erickson hereby represents and warrants that he is not subject
        to any employment or consulting agreement or similar document, except as
        previously disclosed and delivered to the Company, with a former
        employer or with any business as to which Erickson's engagement by the
        Company and provision of services in the capacity contemplated would be
        a breach. For that reason, Erickson hereby represents and warrants that
        he is not subject to any agreement which prohibits him during a period
        of time which extends through the Term from any of the following: (i)
        providing services for the Company in the capacity contemplated by this
        Agreement; (ii) competing with, or in any way participating in a
        business which includes the Company's business; (iii) soliciting
        personnel of such former employer or other business to leave such former
        employer's




                                       6


        employment or to leave such other business; or (iv) soliciting customers
        of such former employer or other business on behalf of another business.

        7. Remedies and Enforceability.

                Erickson agrees that the covenants and agreements contained in
        Section 5 hereof are of the essence of this Agreement; that each of such
        covenants is reasonable and necessary to protect and preserve the
        interests and properties of the Company; that irreparable loss and
        damage will be suffered by the Company should Erickson breach any of
        such covenants and agreements; that each of such covenants and
        agreements is separate, distinct and severable not only from the other
        of such covenants and agreements but also from the other and remaining
        provisions of this Agreement; that the unenforceability of any such
        covenant or agreement shall not affect the validity or enforceability of
        any other such covenant or agreements or any other provision or
        provisions of this Agreement; and that, in addition to other remedies
        available to it, the Company shall be entitled to seek specific
        performance of this Agreement and to seek both temporary and permanent
        injunctions to prevent a breach or contemplated breach by Erickson of
        any of such covenants or agreements.

        8. Notice.

                All notices, requests, demands and other communications required
        hereunder shall be in writing and shall be deemed to have been duly

        this Agreement.

                (b) Waiver. The waiver by the Company of any breach of this
        Agreement by any party shall not be effective unless in writing, and no
        such waiver shall constitute the waiver of the same or another breach on
        a subsequent occasion.

                (c) Governing Law. This Agreement shall be governed by and
        construed in accordance with the internal laws of the State of Texas.
        The parties agree that any appropriate state or federal court located in
        Austin, Texas shall have jurisdiction of any case or controversy arising
        under or in connection with this Agreement and shall be a proper forum
        in which to adjudicate such case or controversy. The parties consent to
        the jurisdiction of such courts.

                (d) Entire Agreement. This Agreement embodies the entire
        agreement of the parties hereto relating to the subject matter hereof
        and supersedes all oral agreements, and to the extent inconsistent with
        the terms hereof, all other written agreements.

                (e) Amendment. This Agreement may not be modified, amended,
        supplemented or terminated except by a written instrument executed by
        the parties hereto.

                (f) Severability. Each of the covenants and agreements
        hereinabove contained shall be deemed separate, severable and
        independent covenants, and in the event that any covenant shall be
        declared invalid by any court of competent jurisdiction, such invalidity
        shall not in any manner affect or impair the validity or enforceability
        of any other part or provision of such covenant or of any other covenant
        contained herein.

                (g) Captions and Section Headings. Except as set forth in
        Section 1 hereof, captions and section headings used herein are for
        convenience only and are not a part of this Agreement and shall not be
