                            GX TECHNOLOGY CORPORATION
                           EMPLOYEE STOCK OPTION PLAN

      1. Purpose. This 1994 Stock Option Plan (the "Plan") is intended to
encourage stock ownership by employees and directors of GX TECHNOLOGY
CORPORATION, a Texas corporation (the "Corporation"), and its Subsidiary
Corporations, including in the Section 4.2 below a specified contractor, so that
they may acquire or increase their proprietary interest in the Corporation; and
to encourage such employees and directors to remain in the employ of the
Corporation and to put forth maximum efforts for the success of the business. It
is further intended that options granted by the Committee (as defined in Section
2 below) pursuant to Section 5 hereof shall constitute "incentive stock options"
("Incentive Stock Options") within the meaning of IRC Section 422, as amended,
and the Regulations issued thereunder (the "Code"), and options granted by the
Committee pursuant to Section 6 hereof shall constitute "nonqualified stock
options" ("Nonqualified Stock Options") that, together with Incentive Stock
Options, are referred to herein as "Options".

      2. Administration. The Plan shall be administered by the Stock Option and
Compensation Committee (the "Committee"), consisting of not less than two
members of the Board of Directors of the Corporation (the "Board"), none of whom
are or shall have been for at least one year prior to such appointment, eligible
to participate in the Plan or any other plan of the Corporation or any of its
predecessor entities entitling the participants therein to acquire stock, stock
options or stock appreciation rights of the Corporation or any of said entities.
The initial Committee shall consist of Thomas D. Barrow and the Board designee
of Nationsbanc Capital Corporation pursuant to the Securityholders Agreement
with the Corporation dated November 2, 1994, presently Douglas C. Williamson.

      2.1 Authority. The Committee shall have the authority in its discretion,
subject to and not inconsistent with the express provisions of the Plan, to
administer the Plan and to exercise all the powers and authorities either
specifically granted to it under the Plan, or necessary or advisable in the
administration of the Plan, including, without limitation, the authority to
grant Options; to determine which Options shall constitute Incentive Stock
Options and which Options shall constitute Nonqualified Stock Options; to
determine the purchase price of the shares of Common Stock covered by each
Option (the "Option Price"); to determine the persons to whom, and the time or
times at which, Options shall be granted; to determine the number of shares of
Common Stock to be covered by each Option; to interpret the Plan; to prescribe,
amend and rescind rules and Regulations relating to the Plan; to determine the
terms and provisions of the Option Agreements (which need not be identical)
evidencing Options granted under the Plan; and to make all other determinations
deemed necessary or advisable for the administration of the Plan. This authority
does not extend to the Common Stock or the granting of the Nonqualified Stock
Options of Sections 4.2 and 6 hereof respectively, said Options being those
granted as of October 31, 1994 to meet contractual commitments of employees and
a contractor of GX Technology L.P. The Committee may delegate to one or more of
its members or to one or more agents such administrative duties as it may deem
advisable, and the Committee or any delegate may employ one or more persons to
render advice with respect to any responsibility the Committee or such person
may have under the Plan.
<PAGE>
      2.2 Rules. The Board shall fill all vacancies, however caused, in the
Committee. The Board may from time to time appoint additional members to the
Committee, and may at any time remove one or more Committee members and
substitute others. One member of the Committee shall be selected by the Board as
chairman. The Committee shall hold its meeting at such times and places as it
shall deem advisable. All determinations of the Committee shall be made by a
majority of its members either present in person or participating by conference
telephone at a meeting or by written consent. The Committee may appoint a
secretary and make such rules and regulations for the conduct of its business as
it shall deem advisable, and shall keep minutes of its meetings.

      2.3 Liability. No member of the Board or Committee shall be liable for any
action taken or determination made in good faith with respect to the Plan or any
Option.

      3. Eligibility. Options may be granted to employees, Directors of the
Corporation or its present or future divisions and Subsidiary Corporations,
including in the Section 4.2 below a specified contractor. In determining the
persons to whom Options shall be granted and the number of shares to be covered
by each Option, the Committee shall take into account the duties of the
respective persons, their present and potential contributions to the success of
the Corporation sad such other factors as the Committee shall deem relevant in
connection with accomplishing the purpose of the Plan. A person to whom an
Option has been granted is sometimes referred to herein as an "Optionee." An
Optionee shall be eligible to receive more than one Option during the term of
the Plan, but only on the terms and subject to the restrictions hereinafter set
forth.

      4. Shares. The shares subject to Options hereunder shall be shares of the
Corporation's Common Stock (the "Common Stock"). Such shares may, in whole or in
part, be authorized but unissued shares or, shares that shall have been or that
may be reacquired by the Corporation.

      4.1 The aggregate number of shares of Common Stock as to which Incentive
Stock Options of Section 5 hereof may be granted from time to time under the
Plan shall not exceed 137,628 shares, provided also that a portion of these
shares shall be reserved for non-employee directors, new employees and other
members of management that are not currently shareholders of the Corporation and
that a portion of these shares may be granted to the Managers as defined in the
Stock Purchase Agreement dated November 2, 1994. The limitation established by
the preceding sentence shall be subject to adjustment as provided in Section 7.9
hereof. If any outstanding Incentive Stock Option expires or is terminated
without having been exercised in full, the shares of Common Stock allocable to
the unexercised portion of such Option shall (unless the Plan shall have been
terminated) become available for subsequent grants of Incentive Stock Options.

      4.2 The aggregate number of shares of Common Stock as to which
Nonqualified Stock Options of Section 6 hereof may be granted under the Plan
shall not exceed 261,500 shares, with the same to be issued within five (5) days
of approval of this Plan by the shareholder or shareholders of the Corporation
to the former owners of the Restricted Units under the Restricted Partnership
Unit Plan and the former owners of the Unit Options under the Employee Unit
Purchase Plan of GX Technology L.P., as a predecessor entity of the Corporation.

      5. Incentive Stock Options. Options granted pursuant to this Section 5 are
intended to constitute Incentive Stock Options and shall be subject to the
following special terms and conditions, in addition to the general terms and
conditions specified in Section 7 hereof.

      5.1 Value of Shares. The aggregate Fair Market Value (determined as of the
date the Incentive Stock Option is granted) of the shares of Common Stock with
respect to which Options granted under this Plan and all other option plans of
the Corporation and any Subsidiary Corporation become exercisable for the first
time by an Optionee during any calendar year shall not exceed $100,000.

      5.2 Ten Percent Stockholder. In the case of an Incentive Stock Option
granted to a 10% Stockholder, (a) the Option Price shall not be less than 110%
of the Fair Market Value of the shares of Common Stock of the Corporation on the
date of grant of such Incentive Stock Option, and (b) the exercise period shall
not exceed 5 years from the date of grant of such Incentive Stock Option.

      5.3 Vesting of Options. The Incentive Stock Options shall have a minimum
vesting of twenty-five percent (25%) over each of the four (4) years following
the date such an Option is granted.

      6. Nonqualified Stock Options. Options greeted pursuant to this Section 6
are intended to constitute Nonqualified Stock Options to be valid for a period
of ten (10) years from date of granting, the vesting and exercise prices per
share to be in accordance with the specific provisions of the Nonqualified
Option Agreements as set forth below, and shall be subject to the general terms
and conditions specified in Section 7 hereof.

      6.1 The Nonqualified Stock Options that are to be issued to replace the
Restricted Units noted in Section 4.2 above shall have an exercise price of five
cents ($.05) per share and shall have the same vesting period(s) as provided in
the Restricted Unit Agreements undertaken in connection with the granting of
said Restricted Units to the employees, Directors or a contractor of GX
Technology L.P. as a predecessor entity of the Company.

      6.2 The Nonqualified Stock Options that are to be issued to replace the
Option Units noted in Section 4.2 above shall have an exercise price of five
dollars ($5.00) per share and shall have the same vesting period(s) as provided
in the Employee Unit Purchase Agreements undertaken in connection with the
granting of said Unit Options to the employees and Directors of GX Technology
L.P. as a predecessor entity of the Company.

      7. Terms and Conditions of Options. Each Option shall be evidenced by a
written Option Agreement between the Corporation and the Optionee, which
agreement shall comply with and be subject to the following terms and
conditions:

      7.1 Number of Shares. Each Option Agreement shall state the number of
shares of Common Stock to which the Option relates.

      7.2 Type of Option. Each Option Agreement shall specifically identify the
portion, if any, of the Option which constitutes an Incentive Stock Option and
the portion, if any, which constitutes a Nonqualified Stock Option.


                                       3
<PAGE>
      7.3 Option Price. Each Option Agreement shall state the Option Price
which, in the case of Incentive Stock Options, shall be not less than 100% of
the Fair Market Value of the shares of Common Stock of the Corporation on the
date of grant of the Option. The Option Price shall be subject to adjustment as
provided in Section 7.9 hereof. The date on which the Committee adopts a
resolution expressly granting an Option shall be considered the day on which
such Option is granted.

      7.4 Medium and Time of Payment. The Option Price shall be paid in full, at
the time of exercise, in cash or in shares of Common Stock having a Fair Market
Value equal to such Option Price or in a combination of cash and such shares,
and may be effected in whole or in part (a) with monies received from the
Corporation at the time of exercise as a compensatory cash payment, or (b) with
monies borrowed from the Corporation pursuant to repayment terms and conditions
as shall be determined from time to time by the Committee, in its discretion,
separately with respect to each exercise of Options and each Optionee; provided,
however, that each such method and time for payment and each such borrowing and
terms and conditions of repayment shall be permitted by and be in compliance
with applicable law, and provided, further, if the Option Price is paid with
monies borrowed from the Corporation, such fact shall be noted conspicuously on
the certificate evidencing such shares in accordance with applicable law.

      7.5 Term and Exercise of Options. Options shall be exercisable over the
exercise period as and at the times and upon the conditions that the Committee
may determine, as reflected in the Option Agreement; provided, however, that the
Committee shall have the authority to accelerate the exercisability of any
outstanding Option at such time and under such circumstances as it, in its sole
discretion, deems appropriate. The exercise period shall be determined by the
Committee for all Options; provided, however that such exercise period shall not
exceed 10 years from the date of grant of such Option. The exercise period shall
be subject to earlier termination as provided in Sections 7.6 and 7.7 hereof. An
Option may be exercised, as to any or all full shares of Common Stock as to
which the Option has become exercisable, by giving written notice of such
exercise to the Committee; provided, however, that an Option may not be
exercised at any one time as to fewer than 100 shares (or such number of shares
as to which the Option is then exercisable if such number of shares is less than
100).

      7.6 Termination. Except as provided in Section 7.5 and in this Section 7.6
hereof, an Option may not be exercised unless the Optionee is then in the employ
of the Corporation or a division or Subsidiary Corporation (or a corporation
issuing or assuming the Option in a transaction to which IRC Section 424(a)
applies), and unless the Optionee has remained continuously so employed since
the date of grant of the Option. If the employment of an Optionee shall
terminate (other than by reason of death, disability or retirement), all Options
of such Optionee that are exercisable at the time of such termination may,
unless earlier terminated in accordance with their terms, be exercised within
three months after such termination; provided, however, that if the employment
of an Optionee shall terminate for cause, all Options theretofore granted to
such Optionee shall, to the extent not theretofore exercised, terminate
forthwith. Nothing in the Plan or in any Option shall confer upon an individual
any right to continue in the employ of the Corporation or any of its divisions
or Subsidiary Corporations or interfere in any way with the right of the
Corporation or any such division or Subsidiary Corporation to terminate such
employment.


                                       4
<PAGE>
      7.7 Death, Disability, or Retirement. If an Optionee shall die while
employed by the Corporation, or a Subsidiary Corporation thereof, or within
three months after the termination of such Optionee's employment, other than for
cause, or if the Optionee's employment shall terminate by reason of disability
or retirement, all Options theretofore granted to such Optionee (to the extent
otherwise exercisable) may, unless earlier terminated in accordance with their
terms, be exercised by the Optionee or by the Optionee's estate or by a person
who acquired the right to exercise such Option by bequest or inheritance or
otherwise by reason of the death or disability of the Optionee, at any time
within one year after the date of death, disability or retirement of the
Optionee.

      7.8 Nontransferability of Options. Options granted under the Plan shall
not be transferable otherwise than (a) by will; or (b) by the laws of descent
and distribution. Options may be exercised, during the lifetime of the Optionee,
only by the Optionee, his or her guardian, or legal representative.

      7.9 Effect of Certain Changes.

            (1) If there is any change in the number of shares of Common Stock
      through the declaration of stock dividends, or through recapitalization
      resulting in stock splits, or combinations or exchanges of such shares,
      the number of shares of Common stock available for Options, the number of
      such shares covered by outstanding Options and the price per share of such
      Options shall be proportionately adjusted by the Committee to reflect any
      increase or decrease in the number of issued shares of Common Stock;
      provided, however, that any fractional shares resulting from such
      adjustment shall be eliminated.

            (2) In the event of the proposed dissolution or liquidation of the
      Corporation, in the event of any corporate separation or division,
      including, but not limited to, split-up, split-off or spin-off, or in the
      event of a merger or consolidation of the Corporation with another
      corporation, the Committee may provide that the holder of each Option then
      exercisable shall have the right to exercise such Option (at its then
      Option Price) solely for the kind and amount of shares of stock and other
      securities, property, cash or any combination thereof receivable upon such
      dissolution, liquidation, or corporate separation or division, or merger
      or consolidation by a holder of the number of shares of Common Stock for
      which such Option might have been exercised immediately prior to such
      dissolution, liquidation, or corporate separation or division, or merger
      or consolidation; or the Committee may provide, in the alternative, that
      each Option granted under the Plan shall terminate as of a date to be
      fixed by the Committee; provided, however, that not less than 30-days'
      written notice of the date so fixed shall be given to each Optionee, who
      shall have the right, during the period of 30 days preceding such
      termination, to exercise the Options as to all or any part of the shares
      of Common Stock covered thereby, including shares as to which such Options
      would not otherwise be exercisable; provided, further, that failure to
      provide such notice shall not invalidate or affect the action with respect
      to which such notice was required.

            (3) If while unexercised Options remain outstanding under the Plan,
      the stockholders of the Corporation approve a definitive agreement to
      merge or consolidate

                                       5
<PAGE>
      the Corporation with or into another corporation or to sell or otherwise
      dispose of all or substantially all of its assets, or adopt a plan of
      liquidation (each, a "Disposition Transaction"), then the Committee may
      (a) make an appropriate adjustment to the number and class of shares
      available for options, and to the amount and kind of shares or other
      securities or property (including cash) receivable upon exercise of any
      outstanding options after the effective date of such transaction, and the
      price thereof, or, in lieu of such adjustment, provide for the
      cancellation of all options outstanding at or prior to the effective date
      of such transaction; (b) provide that exercisability of all Options shall
      be accelerated, whether or not otherwise exercisable; or (c) in its
      discretion, permit Optionees to surrender outstanding options for
      cancellation; provided, however, that if the stockholders approve such
      Disposition Transaction within five years of the date of adoption of this
      Plan and before the Corporation is taken public, the Committee shall
      provide for the alternative in (b) above. Upon any cancellation of an
      outstanding Option pursuant to this Section, the Optionee shall be
      entitled to receive, in exchange therefor, a cash payment under any such
      Option in an amount per share determined by the Committee in its sole
      discretion, but not less than the difference between the per share
      exercise price of such Option and the Fair Market Value of a share of the
      Corporation Common Stock on such date as the Committee shall determine.

            (4) Paragraphs (2) and (3) of this Section 7.9 shall not apply to a
      merger or consolidation in which the Corporation is the surviving
      corporation and shares of Common Stock are not converted into or exchanged
      for stock, securities of any other corporation, cash or any other thing of
      value. Notwithstanding the preceding sentence, in case of any
      consolidation or merger of another corporation into the Corporation in
      which the Corporation is the surviving corporation and in which there is a
      reclassification or change (including a change to the right to receive
      cash or other property) of the shares of Common Stock (other than a change
      in par value, or from par value to no par value, or as a result of a
      subdivision or combination, but including any change in such shares into
      two or more classes or series of shares), the Committee may provide that
      the holder of each Option then exercisable shall have the right to
      exercise such Option solely for the kind and amount of shares of stock and
      other securities (including those of any new direct or indirect parent of
      the Corporation), property, cash or any combination thereof receivable
      upon such reclassification, change, consolidation or merger by the holder
      of the number of shares of Common Stock for which such Option might have
      been exercised.

            (5) In the event of a change in the Common Stock of the Corporation
      as presently constituted which is limited to a change of all of its
      authorized shares with par value into the same number of shares with a
      different par value or without par value, the shares resulting from any
      such change shall be deemed to be the Common Stock within the meaning of
      the Plan.

            (6) To the extent that the foregoing adjustments relate to stock or
      securities of the Corporation, such adjustments shall be made by the
      Committee, whose determination in that respect shall be final, binding and
      conclusive, provided that each Incentive Stock Option granted pursuant to
      this Plan shall not be adjusted in a manner that causes such option to
      fail to continue to qualify as an Incentive Stock Option within the
      meaning of IRC Section 422.


                                       6
<PAGE>
            (7) Except as hereinbefore expressly provided in this Section 7.9,
      the Optionee shall have no rights by reason of any subdivision or
      consolidation of shares of stock or any class or the payment of any stock
      dividend or any other increase or decrease in the number of shares of
      stock of any class or by reason of any dissolution, liquidation, merger,
      or consolidation or spin-off of assets or stock of another corporation;
      and any issue by the Corporation of shares of stock of any class shall not
      affect, and no adjustment by reason thereof shall be made with respect to,
      the number or price of shares of Common Stock subject to the Option. The
      grant of an Option pursuant to the Plan shall not affect in any way the
      right or power of the Corporation to make adjustments, reclassifications,
      reorganizations or changes of its capital or business structures or to
      merge or to consolidate or to dissolve, liquidate or sell, or transfer all
      or part of its business or assets.

      7.10 Rights as a Shareholder. An Optionee or a transferee of an Option
shall have no rights as a shareholder with respect to any shares covered by the
Option until the date of the issuance of a certificate evidencing such shares.
No adjustment shall be made for dividends (ordinary or extraordinary, whether in
cash, securities or other property) or distribution of other rights for which
the record date is prior to the date such certificate is issued, except as
provided in Section 7.9 hereof.

      7.11 Other Provisions. The Option Agreements authorized under the Plan
shall contain such other provisions, including, without limitation, (a) the
imposition of restrictions upon the exercise of an Option; (b) in the case of an
Incentive Stock Option, the inclusion of any condition not inconsistent with
such Option qualifying as an Incentive Stock Option; and (c) conditions relating
to compliance with applicable federal and state securities laws, as the
Committee shall deem advisable.

      8. Agreement By Optionee Regarding Withholding Taxes. If the Committee
shall so require, as a condition of the exercise, each Optionee shall agree that
(a) no later than the date of exercise of any Option, the Optionee will pay to
the Corporation or make arrangements satisfactory to the Committee regarding
payment of any federal, state or local taxes of any kind required by law to be
withheld upon the exercise of such Options, and (b) the Corporation shall, to
the extent permitted or required by law, have the right to deduct federal, state
and local taxes of any kind required by law to be withheld upon the exercise of
such Option from any payment of any kind otherwise due to the Optionee.

      9. Term of Plan. Options may be granted pursuant to the Plan from time to
time within a period of 10 years from the date the Plan is approved by the
stockholders of the Corporation.

      10. Definitions. As used in this Plan, the following words and phrases
shall have the meanings indicated:

            (a) "DISABILITY" shall mean an Optionee's inability to engage in any
      substantial gainful activity by reason of any medically determinable
      physical or mental impairment that can be expected to result in death or

      less than twelve (12) months.

      over-the-counter market for the last preceding date on which there was a
      sale of such Common Stock in such market; or (iii) in case no reported

      professional appraiser(s).

            (c) "PARENT CORPORATION" shall mean any corporation (other than the
      Corporation) in an unbroken chain of corporations ending with the employer
      corporation if, at the time of granting an Option, each of the
      corporations other than the employer corporation owns stock possessing 50%

      11. Amendment and Termination of the Plan. The Board at any time and from
time to time may suspend, terminate, modify or amend the Plan; provided,
however, that any amendment that would materially increase the aggregate number
of shares of Common Stock as to which Options may be granted under the Plan or
materially increase the benefits accruing to participants under the Plan or
materially modify the requirements as to eligibility for participation in the
Plan shall be subject to the approval of the holders of a majority of the Common
Stock issued and outstanding, except that any such increase or modification that
may result from adjustments authorized by section 7.9 hereof shall not require
such approval. Except as provided in Section 7 hereof, no suspension,
termination, modification or amendment of the Plan may adversely affect any
Option previously granted, unless the written consent of the Optionee is
obtained.
