EMPLOYMENT AGREEMENT

THIS EMPLOYMENT AGREEMENT (this “Agreement”) is made and entered into as of July 1, 2009 (the “Effective Date”) by and between Luminex Corporation, a Delaware corporation (“Luminex”) and Michael F. Pintek (“Executive”).

RECITAL

WHEREAS, Executive is to be employed as the Senior Vice President, Operations for Luminex;

WHEREAS, Luminex and Executive wish to document the terms of the employment of Executive in such capacity; and

WHEREAS, Executive has represented to Luminex and Luminex has relied on Executive’s representation that the execution of this Agreement by Executive, and the provision of services by Executive to Luminex as contemplated in this Agreement, will not conflict with, or cause Executive or any other person or entity to be in breach of, (i) any other contract to which Executive is a party or (ii) any duty which Executive may owe to any other person or entity.

AGREEMENT

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties agree as follows:

1. Duties.

1.1 Duties. During the term of this Agreement (including all renewal periods, if any, the “Term”), Executive agrees to be employed by and to serve as Senior Vice President, Operations and Luminex agrees to employ and retain Executive in such capacity subject to the provisions of this Agreement. Executive shall have such powers, authority and duties, and shall render such services of executive and administrative character, or act in such other capacity for Luminex, as the Chief Executive Officer or the Board of Directors of Luminex (the “Board”) shall from time to time lawfully direct and Executive shall report directly to the Chief Executive Officer of Luminex. Executive shall devote all of his business time, energy, and skill to the business of Luminex;

2. Term and Termination.

2.1 Term. Subject to Section 2.2, the term of employment of Executive by Luminex shall be two (2) years commencing on the Effective Date and shall thereafter automatically renew for successive additional one-year terms unless either party provides the

Confidential

other with written notice of its intent not to renew this Agreement at least sixty (60) days prior to the end of the Term (unless terminated earlier pursuant to the provisions of this Agreement).

2.2 Termination of Employment.

2.2.1 Termination For Cause. “Termination For Cause” shall mean the termination by Luminex of Executive’s employment with Luminex as the result of Executive’s material fraud upon Luminex, violation of the law or Executive’s material breach of this Agreement after receipt of written notice from Luminex specifying such breach and failure by Executive to cure such breach within fifteen (15) days from receipt of such notice. Executive’s inability to perform his obligations under this Agreement despite his best efforts as a result of a permanent or temporary disability (as evidenced by a written determination from a physician chosen by Executive and reasonably acceptable to Luminex) shall not result in a Termination For Cause. In the event that Executive fails to cure the breach within the fifteen (15) day cure period, the termination shall be effective as of the date that Luminex notifies Executive of his termination following the expiration of the fifteen (15) day cure period. Upon any Termination For Cause, Executive shall be paid the Accrued Obligations (defined below) within three (3) business days following the effective date of termination.

2.2.2 Termination Other Than For Cause. “Termination Other Than For Cause” shall mean (i) termination by Luminex of Executive’s employment with Luminex for any reason other than Termination For Cause, Termination by Reason of Death, Termination by Reason of Incapacity or Termination Upon Expiration of Agreement or (ii) termination by Executive upon constructive termination of Executive’s employment with Luminex by reason of (A) a reduction in Executive’s Base Salary (defined below); (B) a reduction in Executive’s title from Chief Operating Officer for Luminex (whether by reason of Executive’s removal from any of such offices or Luminex’s failure to reappoint Executive to any of such offices); (C) a Material Diminution (defined below); (D) a requirement that Executive change his principal place of business to a location that is outside the Office Area (defined below), or (E) Luminex’s continued material breach of this Agreement after receipt of written notice from Executive specifying such breach and failure by Luminex to cure such breach within fifteen (15) days from receipt of such notice. Termination Other Than For Cause may be effected by Luminex at any time by providing Executive with written notice of such termination. The termination shall be effective as of the date of the notice or such later date as may be determined by Luminex. Executive may also effect a Termination Other Than For Cause upon written notice to Luminex at any time any of the conditions for constructive termination set forth in clause (ii) above (including without limitation, if applicable, the expiration of the cure period) have been met. Upon any Termination Other Than For Cause, Executive shall be paid (i) within three (3) business days following the effective date of termination the amount of the Accrued Obligations and (ii) all severance compensation provided in Section 4.1. For purposes of this Agreement, “Material Diminution” means a material diminution by Luminex of Executive’s duties, powers, authority, functions or responsibilities without Executive’s consent, such that Executive is left with such duties, powers, authority, functions and responsibilities (when viewed in the aggregate) that are materially diminished compared to both (i) those duties, powers, authority, functions and responsibilities conferred upon Executive at the Effective Date and (ii) those duties, powers, authority, functions and responsibilities that are most typically conferred upon

Execution Version

the chief operating officer of companies having both (i) a chief operating officer and (ii) revenues comparable to Luminex (based on the revenues of Luminex at the time of determination). Luminex and Executive agree that in the event there is an ambiguity with respect to the interpretation or application of the definition of “Material Diminution”, such ambiguity shall be resolved according to the reasonable interpretation of such definition most favorable to Luminex. For purposes of this Agreement, “Office Area” means the geographical area within a 40 mile radius of Luminex’s current principal office at 12212 Technology Blvd., Austin, Texas.

2.2.3 Actual Voluntary Termination. “Actual Voluntary Termination” shall mean termination by Executive of Executive’s employment with Luminex for any reason other than Termination For Cause, Termination Other Than For Cause, Termination by Reason of Death or Termination by Reason of Incapacity. In the event of an Actual Voluntary Termination, Executive shall be paid within fifteen (15) business days following the effective date of termination the amount of the Accrued Obligations.

2.2.4 Termination by Reason of Incapacity. If, during the Term, Executive shall become Permanently Disabled (defined below), Luminex may terminate Executive’s employment with Luminex effective on the earliest date permitted under applicable law, if any, and such termination shall be deemed “Termination by Reason of Incapacity”. Upon termination of employment under this Section, Executive shall be paid (i) within three (3) business days following the effective date of termination the amount of the Accrued Obligations and (ii) all severance compensation provided in Section 4.2. As used herein, Executive shall be deemed “Permanently Disabled” if Executive is (i) collecting long-term disability payments under a long-term disability plan established for the benefit of Luminex’s employees or executives generally or a reasonably similar plan or (ii) if, and only if, no such long-term disability plan is in effect at the time of determination, a physician selected by Luminex and reasonably acceptable to Executive makes a written determination that Executive is unable to perform his obligations under this Agreement despite his best efforts by reason of any medically determinable physical or mental impairment that can be expected to result in death or that has lasted or can be expected to last for a continuing period of not less than 12 months.

2.2.5 Termination by Reason of Death. In the event of Executive’s death during the Term, Executive’s employment with Luminex shall be deemed to have terminated as of the date on which his death occurs and the estate of Executive shall be paid (i) within fifteen (15) days following the effective date of termination the amount of the Accrued Obligations and (ii) all severance compensation provided in Section 4.3.

2.2.6 Termination Upon Expiration of Agreement. In the event that Luminex refuses for any reason to extend this Agreement by giving written notice at least 60 days prior to the initial or any renewal period as set forth in Section 2.1, Executive shall be paid (i) within three (3) business days following the effective date of termination the amount of the Accrued Obligations and (ii) all severance compensation provided in Section 4.4. In the event that Executive refuses for any reason (except as otherwise provided herein) to extend this Agreement by giving written notice at least 60 days prior to the initial or any renewal period as set forth in Section 2.1, the termination shall be deemed an Actual Voluntary Termination.

Execution Version

2.2.7 Termination of Relationship with Affiliated Entities. Unless agreed by Luminex (or a subsidiary thereof) and Executive in a separate written agreement (other than corporate minutes, resolutions, charter documents, bylaws and partnership agreements), upon the termination of Executive’s employment with Luminex for any reason, Executive shall tender a written resignation of any positions he may have with Luminex and any and all of Luminex’s direct and indirect subsidiaries.

2.2.8 Definition of Accrued Obligations. As used in this Agreement, “Accrued Obligations” means all accrued but unpaid salary, accrued but unpaid vacation, sick leave, and similar pay (all determined in accordance with Luminex’s policies then in effect), and any appropriate business expenses incurred by Executive in connection with his duties hereunder, all to the date of termination.

3. Salary, Benefits and Bonus Compensation.

3.1 Base Salary. As payment for the services to be rendered by Executive as provided in Section 1 and subject to the terms and conditions of Section 2, Luminex agrees to pay to Executive a “Base Salary” at the rate of $13,125.00 per each semi-monthly pay period or $315,000 per annum (or such greater amount as may be determined from time to time by the Board or the Compensation Committee thereof) payable in accordance with the then-current payroll policies of Luminex.

3.2 Signing Bonus. Executive shall receive an initial signing bonus in the amount of $100,000, payable to Executive upon the Effective Date of this Agreement (the “Signing Bonus”). Executive may receive an additional discretionary signing bonus (the “Additional Signing Bonus”) at the sole discretion of the Compensation Committee of the Company’s Board of Directors. In addition, the Company shall pay an additional amount to Executive, calculated as hereinafter described, designed to reimburse Executive for any federal and state income and Medicare tax withholdings required by applicable law on the Signing Bonus and the Additional Signing Bonus (the “Gross-up Amount”). Executive agrees that he shall be obligated to promptly repay to Company the “pro rata amount” of the aggregate amount of the Signing Bonus and the Additional Signing Bonus (if any) and the Gross-up Amount (the “Total Signing Bonus”) in the event of “Termination for Cause” pursuant to Section 2.2.1 or in the event of “Actual Voluntary Termination” pursuant to Section 2.2.3 within three (3) years of the Effective Date.  The “pro rata amount” shall be determined by multiplying the Total Signing Bonus by a fraction determined by dividing the number of days remaining from the date of the termination event through the date that is three (3) years from the Effective Date, by 1095. The Gross-up Amount shall be determined by dividing the aggregate amount of the Signing Bonus and, if applicable the Additional Signing Bonus, by .635, which applies the federal income tax at a 35% rate, Medicare tax at a 1.45% rate and no state income tax. In the event state income tax shall be applicable to these payments, an appropriate adjustment for the net applicable state income tax rate shall be made to this calculation.

3.3 Annual Bonus. Executive shall be eligible to receive a bonus each year in an amount up to at least fifty percent (50%) of your then-current Base Salary (or such other amount as may otherwise be determined by the Company’s Board of Directors), subject to the

Execution Version

performance criteria established annually by the Company’s Board of Directors and payable during the first quarter of the following year or otherwise as consistent with the timing of other employee bonuses. The Board is under no obligation to declare, and Luminex is under no obligation to pay, any bonus to Executive under the terms of this Agreement. In the event Executive and Luminex are parties to a written agreement or plan executed by both Luminex and Executive that governs bonus arrangements, and the provisions thereof conflict with this Section 3.3, the terms of such other written agreement or plan shall supersede this Section 3.3. Notwithstanding the foregoing, Executive shall be eligible to receive a prorata portion of any bonus awarded for 2009 based on the number of months Executive is employed by the Company during 2009.

3.4 Change in Control. In the event that both (i) a Change in Control (defined below) of Luminex occurs during the Term and (ii) Executive’s employment with Luminex (or, as applicable, its successor in interest) terminates for any reason (including without limitation an Actual Voluntary Termination by Executive) at any time within six (6) months following the occurrence of the Change in Control of Luminex, in lieu of any Severance Compensation then owed or that otherwise would be owed in the future to Executive under Section 4 of this Agreement, Luminex (or its successor in interest) shall pay Executive both the Accrued Obligations and a lump sum payment (the “Change in Control Payment”) in an aggregate amount equal to the sum of (i) the Bonus Amount (defined below), plus (ii) an amount equal to Executive’s annual Base Salary (at the highest rate in effect during the period beginning six months immediately prior to the effective date of the Change of Control through the date of termination) within three (3) business days after the termination of Executive’s employment. In the interest of clarity, Luminex and Executive agree that, upon the termination of Executive’s employment at any time within six (6) months following the occurrence of the Change in Control of Luminex, the provisions of Sections 4.1, 4.2, 4.3, 4.4, and 4.6 shall automatically be deemed null and void and shall not apply with respect to any termination of Executive’s employment (whether such termination is effected in connection with the Change in Control of Luminex or at any time in the future following the Change in Control of Luminex), and under no circumstances shall Luminex ever be obligated to pay Executive both a Change in Control Payment and Severance Compensation under Section 4. For purposes of this Agreement, a “Change in Control” of Luminex shall be deemed to have occurred if, after the date of this Agreement:

(A) any “Person” (as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) (other than an Approved Person (as defined below)) becomes the “Beneficial Owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of a majority or more of the then outstanding Common Stock of Luminex (“Common Stock”) (such Person, an “Acquiring Person”); or

(B) Luminex merges or consolidates with any other corporation or other entity, in each case other than a merger or consolidation which results in the voting securities of Luminex outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) at least a majority of the combined voting power of the voting securities of Luminex or such surviving entity outstanding immediately after such merger or consolidation; or

Execution Version

(C) Luminex sells or disposes of all or substantially all of Luminex’s assets in one transaction or a series of related transactions; or

(D) Luminex files a periodic or current report or proxy statement with the Securities and Exchange Commission (the “SEC”) disclosing that a “change in control” (as such term is used in Item 1 of Form 8-K promulgated by the SEC) of Luminex has occurred; or

(E) If, as a result of nominations made by a person or group other than the Board of Directors of Luminex, individuals who prior to such nominations constitute the Directors of Luminex cease for any reason to constitute at least a majority thereof within the two year period following such nominations.

As used in this Agreement, “Approved Person” means (1) an employee benefit plan of Luminex (or a trustee or other fiduciary holding securities for such a plan), or (2) a corporation owned, directly or indirectly, by the stockholders of Luminex in substantially the same proportions as their ownership of stock of Luminex, or (3) a Person not less than a majority of whose voting securities are Beneficially Owned by Luminex after giving effect to the transaction.

As used in this Agreement, “Bonus Amount” means the annual bonus (if any) received or to be received by Executive under Section 3.2 in respect of the then most recently completed calendar year, or if no determination concerning bonuses has been made for the most recently completed calendar year, then the annual bonus (if any) for the previous calendar year.

Any options (“Options”) granted (including without limitation Options that may be granted in the future) and restricted stock (“Restricted Stock”) issued (including without limitation Restricted Stock that may be issued in the future) to Executive pursuant to any incentive plan of Luminex shall immediately vest upon a Change in Control. Luminex shall take no action to facilitate a transaction involving a Change in Control, including without limitation redemption of any rights issued pursuant to any rights agreement, unless it has taken such action as may be necessary to ensure that Executive has the opportunity to exercise all Options he may then hold, and obtain certificates containing no restrictive legends in respect of any Restricted Stock he may then hold, at a time and in a manner that shall give Executive the opportunity to sell or exchange the securities of Luminex acquired upon exercise of his Options and upon receipt of unrestricted certificates for shares of Common Stock in respect of his Restricted Stock, if any (collectively, the “Acquired Securities”), at the earliest time and in the most advantageous manner any holder of the same class of securities as the Acquired Securities is able to sell or exchange such securities in connection with such Change in Control. Luminex acknowledges that its covenants in the preceding sentence (the “Covenants”) are reasonable and necessary in order to protect the legitimate interests of Luminex in maintaining Executive as one of its employees and that any violation of the Covenants by Luminex would result in irreparable injuries to Executive, and Luminex therefore acknowledges that in the event of any violation of the Covenants by Luminex or its directors, officers or employees, or any of their respective agents, Executive shall be entitled to obtain from any court of competent jurisdiction temporary, preliminary and permanent injunctive relief in order to (i) obtain specific performance of the Covenants, (ii) obtain specific performance of the exercise of his Options, delivery of certificates

Execution Version

containing no restrictive legends in respect of his Restricted Stock and the sale or exchange of the Acquired Securities in the advantageous manner contemplated above or (iii) prevent violation of the Covenants; provided nothing in this Agreement shall be deemed to prejudice Executive’s rights to damages for violation of the Covenants. In the event that the terms of any separate written agreement concerning Options granted or Restricted Stock issued to Executive conflict with the terms of this paragraph, the terms of this paragraph shall control.

3.5 Additional Benefits. During the Term, Executive shall be entitled to the following fringe benefits:

3.5.1 Transitional Expenses. The Company will pay for the following additional expenses upon presentation of applicable receipts: i) the costs of your temporary living until you purchase a home, at a rate of per month to be agreed upon by you and me for up to a period of three (3) months; ii) the costs of a rental car until your automobile arrives in Austin or you purchase an automobile, which is expected to be for a period of no more than one (1) month; iii) the costs of your airfare to and from California for up to two (2) trips per month for a period of up to three (3) months, not to exceed $1,000 per month; iv) the costs of up to two (2) house hunting trips for you and your spouse. 

3.5.2 Benefits and Vacation. Executive shall be eligible to participate in such of Luminex’s benefits and deferred compensation plans as are now generally available or later made generally available to executive officers of Luminex. A termination or expiration of this Agreement for any reason or for no reason shall not affect any rights which Executive may have pursuant to any agreement, policy, plan, program or arrangement of Luminex providing Executive benefits (including under any stock option agreement or bonus plan or agreement which may exist), which rights shall be governed by the terms thereof. Executive shall be entitled to four (4) weeks paid vacation each calendar year (prorated for partial years). Unless approved in advance by the Board or a committee thereof, accrued vacation not taken in any applicable period shall not be carried forward or used in any subsequent period.

3.5.3 Reimbursement for Expenses.

3.5.3.1 Incidental Expenses. Luminex shall reimburse Executive for reasonable and properly documented out-of-pocket business and/or entertainment expenses incurred by Executive in connection with his duties under this Agreement. Any such expenses shall be submitted by Executive to Luminex on a periodic basis and will be paid in accordance with standard Luminex policies and procedures.

3.5.3.2 Moving Expenses. In the event of the relocation of Luminex’s headquarters to a location that is outside the Office Area and Executive elects to relocate, Luminex shall (i) reimburse Executive for any reasonable, out-of-pocket and adequately documented moving expenses incurred by Executive in connection with the transfer of his residence and (ii) pay to an Executive an amount of cash reasonably calculated by Luminex to negate adverse income tax consequences to Executive of the foregoing reimbursement.

4.6 Conditions to Payment; Sole Remedy. Executive shall not be entitled to receive any compensation or other payment pursuant to Sections 4.1, 4.2 or 4.4 unless Executive shall have executed and delivered to Luminex a release substantially in the form attached hereto as Exhibit “A” and, provided Luminex has also signed such release within two (2) business days of execution and delivery by Executive, all revocation and waiting periods applicable to such release have expired (if Luminex fails to sign such release, then such revocation and waiting periods shall not apply). In addition, in the event that Executive breaches any of the restrictive covenants set forth in Article 5 at any time, Luminex shall be entitled to discontinue any compensation or other payments pursuant to Sections 4.1, 4.2 or 4.4 (provided, however, that if it is finally determined by a court of competent jurisdiction or an arbitrator that Luminex asserted in bad faith that Executive breached any of the restrictive covenants set forth in Article 5, the payments of the Severance Compensation shall be extended for two months for each calendar month that payments were delayed. The compensation to be paid to Executive pursuant to Sections 4.1, 4.2, 4.3 or 4.4 shall represent the sole and exclusive remedy of Executive in connection with the termination of his employment and this Agreement upon a Termination Other Than for Cause, a Termination by Reason of Incapacity, a termination in connection with Executive’s death, or a refusal by Luminex to extend this Agreement beyond the Term and any extensions thereof.

5. Protection of Luminex.

5.1 Non-Competition. Ancillary to the otherwise enforceable agreements set forth in this Agreement, Executive agrees that during Executive’s employment with Luminex and for a period of one year following termination of employment, whether such termination occurs at the insistence of Executive or Luminex for any reason, Executive shall not compete directly or indirectly in any way with the business of Luminex anywhere in the world where Luminex conducted business during the Term. For purposes of this Agreement, “compete directly or indirectly in any way with the business of Luminex” means to become an employee, consultant, advisor, manager, member, director of or beneficially own more than three percent of any individual, company or entity that competes with Luminex in the Core Business (defined below) at the time of determination.

As used in this Agreement, “Core Business” means the development, manufacturing and/or marketing of multiplexing biological testing technologies with applications in the life-sciences industry.

5.2 Nonsolicitation. Ancillary to the otherwise enforceable agreements set forth in this Agreement, Executive agrees that, for a period of one (1) year subsequent to the termination of Executive’s employment with Luminex, whether such termination occurs at the insistence of Executive or Luminex for any reason, Executive shall not recruit, hire, or attempt to recruit or hire, directly or by assisting others, any other employees of Luminex, nor shall Executive contact or communicate with any other employees of Luminex for the purpose of inducing other employees to terminate their employment with Luminex. For purposes of this covenant, “other employees of Luminex” shall refer to employees who are still actively employed by, or doing business with, Luminex or a subsidiary of Luminex at the time of the attempted recruiting or hiring.

5.3 Remedies. Due to the irreparable and continuing nature of the injury which would result from a breach of the covenants described in Sections 5.1 and 5.2, Executive agrees that Luminex may, in addition to any remedy which Luminex may have at law or in equity, apply to any court of competent jurisdiction for the entry of an immediate order to restrain or enjoin the breach of this covenant and to otherwise specifically enforce the provisions of the covenants set forth in Sections 5.1 and 5.2.

Execution Version

5.4 Acknowledgment. Executive acknowledges and agrees that the restrictions set forth above are ancillary to an otherwise enforceable agreement and supported by independent valuable consideration as required by Tex. Bus. & Comm. Code Ann. § 15.50. Executive further acknowledges and agrees that the limitations as to time, geographical area, and scope of activity to be restrained by Sections 5.1 and 5.2 are reasonable and acceptable to Executive, and do not impose any greater restraint than is reasonably necessary to protect the goodwill and other business interests of Luminex.

5.5 Reformation and Severance. If a judicial determination is made that any of the provisions of the above restriction constitutes an unreasonable or otherwise unenforceable restriction against Executive, it shall be rendered void only to the extent that such judicial determination finds such provisions to be unreasonable or otherwise unenforceable. In this regard, the parties hereby agree that any judicial authority construing this Agreement shall be empowered to sever any portion of the prohibited business activity from the coverage of this restriction and to apply the restriction to the remaining portion of the business activities not so severed by such judicial authority. Moreover, notwithstanding the fact that any provisions of this restriction are determined by a court not to be specifically enforceable through injunctive relief, Luminex shall nevertheless be entitled to seek to recover monetary damages as a result of the breach of any provision which is not reformed by a court. The time period during which the restrictions shall apply shall be tolled and suspended as to Executive for a period equal to the aggregate quantity of time during which Executive violates such prohibitions in any respect.

5.6 Confidential Information and Trade Secrets.

The term “Confidential Information” shall not apply to information which is (i) already in Executive’s possession (unless such information was obtained by Executive from Luminex in the course of Executive’s employment by Luminex); (ii) received by Executive from a third party with, to Executive’s knowledge, no restriction on disclosure or (iii) required to be disclosed by any applicable law or by an order of a court of competent jurisdiction.

Executive recognizes and acknowledges that the Confidential Information constitutes valuable, special and unique assets of Luminex and its affiliates. Except as required to perform Executive’s duties as an Executive of Luminex, until such time as they cease to be Confidential Information through no act of Executive in violation of this Agreement, Executive will not use or disclose any Confidential Information of Luminex.

Executive acknowledges and agrees that all such property, including but not limited to any and all copies thereof, whether prepared by Executive or otherwise in the possession of Executive, are and shall remain the exclusive property of Luminex, that Executive shall have no right or proprietary interest in such property and that Executive will safeguard and return to Luminex all such property upon the earlier of (i) Luminex’s request and (ii) the termination of Executive’s employment with Luminex.
