                               LUMINEX CORPORATION
                        RESTRICTED SHARE AWARD AGREEMENT
                                   (DIRECTORS)

         THIS RESTRICTED SHARE AWARD AGREEMENT (this "Agreement") is made and
entered into as of the _____ day of _______________, 200__ (the "Grant Date"),
between Luminex Corporation, a Delaware corporation (the "Company"), and
_____________________, the "Grantee"). Capitalized terms not otherwise defined
herein shall have the meaning ascribed to such terms in the Luminex Corporation
2006 Equity Incentive Plan (the "Plan").

         WHEREAS, the Company has adopted the Plan, which permits the issuance
of restricted shares of the Company's common stock, par value $0.001 per share
(the "Common Stock"); and

         WHEREAS, pursuant to the Plan, the Board has granted an award of
restricted shares to the Grantee as provided herein;

         NOW, THEREFORE, in consideration of the mutual covenants hereinafter
set forth and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto, intending to
be legally bound hereby, agree as follows:

         1. Grant of Restricted Shares.

            (a) The Company hereby grants to the Grantee an award (the "Award")
of _______________ shares of Common Stock of the Company (the "Shares" or the
"Restricted Shares") on the terms and conditions set forth in this Agreement and
as otherwise provided in the Plan.

            (b) The Grantee's rights with respect to the Award shall remain
forfeitable at all times prior to the dates on which the restrictions shall
lapse in accordance with Section 2 and Section 3 hereof.


         2. Terms and Rights as a Stockholder.

            (a) Except as provided herein and subject to such other exceptions
as may be determined by the Board in its discretion, the "Restricted Period" for
Restricted Shares granted herein shall expire on the date of the annual meeting
of stockholders held in the year following the year in which the Award was made.

            (b) The Grantee shall have all rights of a stockholder with respect
to the Restricted Shares, including the right to receive dividends and the right
to vote such Shares, subject to the following restrictions:

                (i) the Grantee shall not be entitled to delivery of the stock
certificate for any Shares until the expiration of the Restricted Period as to
such Shares;


<PAGE>

                (ii) none of the Restricted Shares may be sold, assigned,
transferred, pledged, hypothecated or otherwise encumbered or disposed of during
the Restricted Period as to such Shares; and

                (iii) except as otherwise determined by the Board at or after
the grant of the Award hereunder, all of the Restricted Shares shall be
forfeited, and all rights of the Grantee to such Shares shall terminate, without
further obligation on the part of the Company, unless the Grantee continues
his/her service as a director of the Company, a Subsidiary or Affiliate for the
entire Restricted Period.

            (c) Notwithstanding the foregoing, the Restricted Period shall
automatically terminate as to all Restricted Shares awarded hereunder (as to
which such Restricted Period has not previously terminated) upon the termination
of the Grantee's service as a director of the Company, a Subsidiary or Affiliate
which results from the Grantee's death or Disability.

            (d) Notwithstanding the foregoing, upon a Change in Control, the
Restricted Period shall automatically terminate as to all Restricted Shares
awarded hereunder (to the extent such Restricted Period has not previously
terminated).

Any Shares, any other securities of the Company and any other property (except
for cash dividends) distributed with respect to the Restricted Shares shall be
subject to the same restrictions, terms and conditions as such Restricted
Shares.

         3. Termination of Restrictions. Following the termination of the
Restricted Period, all restrictions set forth in this Agreement or in the Plan
relating to the Restricted Shares shall lapse and a stock certificate for the
appropriate number of Shares, free of the restrictions and restrictive stock
legend (but subject to any legend appropriate under securities laws), shall,
upon request, be delivered to the Grantee or the Grantee's beneficiary or
estate, as the case may be, pursuant to the terms of this Agreement.

         4. Delivery of Shares.

            (a) As of the date hereof, certificates representing the Restricted
Shares shall be registered in the name of the Grantee and held by the Company or
transferred to a custodian appointed by the Company for the account of the
Grantee subject to the terms and conditions of the Plan and shall remain in the
custody of the Company or such custodian until their delivery to the Grantee or
Grantee's beneficiary or estate as set forth in Section 4(b) hereof or their
reversion to the Company as set forth in Section 2(b) hereof.

            (b) Certificates representing Restricted Shares in respect of which
the Restricted Period has lapsed pursuant to this Agreement shall be delivered
to the Grantee (or Grantee's personal representative, if applicable) upon
request following the date on which the restrictions on such Restricted Shares
lapse.


                                       2

            (c) Each certificate representing Restricted Shares shall bear a
legend in substantially the following form or substance:

         THIS CERTIFICATE AND THE SHARES OF STOCK REPRESENTED HEREBY ARE SUBJECT
         TO THE TERMS AND CONDITIONS (INCLUDING FORFEITURE AND RESTRICTIONS
         AGAINST TRANSFER) CONTAINED IN THE LUMINEX CORPORATION 2006 EQUITY
         INCENTIVE PLAN (THE "PLAN") AND THE RESTRICTED SHARE AWARD AGREEMENT
         (THE "AGREEMENT") BETWEEN THE OWNER OF THE RESTRICTED SHARES
         REPRESENTED HEREBY AND LUMINEX CORPORATION (THE "COMPANY"). THE RELEASE
         OF SUCH SHARES FROM SUCH TERMS AND CONDITIONS SHALL BE MADE ONLY IN
         ACCORDANCE WITH THE PROVISIONS OF THE PLAN AND THE AGREEMENT AND ALL
         OTHER APPLICABLE POLICIES AND PROCEDURES OF THE COMPANY, COPIES OF
         WHICH ARE ON FILE AT THE COMPANY.

         5. Effect of Lapse of Restrictions. To the extent that the Restricted
Period applicable to any Restricted Shares shall have lapsed, the Grantee may
receive, hold, sell or otherwise dispose of such Shares free and clear of the
restrictions imposed under the Plan and this Agreement.

         6. No Right to Continued Service. This Agreement shall not be construed
as giving Grantee the right to continue to service as a director of the Company
or any Subsidiary or Affiliate, and the Company or any Subsidiary or Affiliate
may at any time dismiss Grantee from service as a director, free from any
liability or any claim under the Plan.

         7. Adjustments. The Board may make adjustments in the terms and
conditions of, and the criteria included in, this Award in recognition of
unusual or nonrecurring events (including, without limitation, the events
described in Section 4.2 of the Plan) affecting the Company, any Subsidiary or
Affiliate, or the financial statements of the Company or any Subsidiary or
Affiliate, or of changes in applicable laws, regulations, or accounting
principles, whenever the Board determines that such adjustments are appropriate
in order to prevent dilution or enlargement of the benefits or potential
benefits intended to be made available under the Plan.

         8. Amendment to Award. Subject to the restrictions contained in the
Plan, the Board may waive any conditions or rights under, amend any terms of, or
alter, suspend, discontinue, cancel or terminate, the Award, prospectively or
retroactively; provided that any such waiver, amendment, alteration, suspension,
discontinuance, cancellation or termination that would adversely affect the
rights of the Grantee or any holder or beneficiary of the Award shall not to
that extent be effective without the consent of the Grantee, holder or
beneficiary affected.

         9. Withholding of Taxes. The Company may take such actions as it deems
necessary to satisfy any withholding obligations or withholding taxes applicable
to the Company or the Grantee.

the Plan and agrees to be bound by all the terms and provisions thereof. The
terms of this Agreement are governed by the terms of the Plan, and in the case
of any inconsistency between the terms of this Agreement and the terms of the
Plan, the terms of the Plan shall govern.

         11. Severability. If any provision of this Agreement is, or becomes, or
is deemed to be invalid, illegal, or unenforceable in any jurisdiction or as to
any Person or the Award, or would disqualify the Plan or Award under any laws
deemed applicable by the Board, such provision shall be construed or deemed
amended to conform to the applicable laws, or if it cannot be construed or
deemed amended without, in the determination of the Board, materially altering
the intent of the Plan or the Award, such provision shall be stricken as to such
jurisdiction, Person or Award, and the remainder of the Plan and Award shall
remain in full force and effect.
