     The following amendment to the Articles of Incorporation of the Corporation
was adopted by the shareholders of the Corporation by unanimous written consent
pursuant to Article 9.10.A of the TBCA. The amendment alters and replaces
Article IV of the Articles of Incorporation of the Corporation (as amended) in
its entirety to read as follows:

     The total number of shares of all classes of capital stock which the
corporation shall have authority to issue is one million two hundred fifty
thousand (1,250,000), of which (a) one million (1,000,000) shares shall be
designated as Common Stock, par value $1.00 per share, and (b) two hundred fifty
thousand (250,000) shares shall be designated as Preferred Stock, par value
$1.00 per share.

     The following is a statement of the designations, preferences, limitations,
and relative rights, including voting rights, in respect of the classes of stock
of the corporation and of the authority with respect thereto expressly vested in
the board of directors of the corporation:

     A. COMMON STOCK

     1. Each share of Common Stock of the corporation shall have identical
rights and privileges in every respect. The holders of shares of Common Stock
shall be entitled to vote upon all matters submitted to a vote of the
shareholders of the corporation and shall be entitled to one vote for each share
of Common Stock held.

     2. Subject to the prior rights and preferences, if any, applicable to
shares of the Preferred Stock or any series thereof, the holders of shares of
the Common Stock shall be entitled to receive such dividends (payable in cash,
stock, or otherwise) as may be declared thereon by the board of directors at any
time and

from time to time out of any funds of the corporation legally available
therefor.

     3. In the event of any voluntary or involuntary liquidation, dissolution,
or winding-up of the corporation, after distribution in full of the preferential
amounts, if any, to be distributed to the holders of shares of the Preferred
Stock or any series thereof, the holders of shares of the Common Stock shall be
entitled to receive all of the remaining assets of the corporation available for
distribution to its shareholders, ratably in proportion to the number of shares
of the Common Stock held by them. A liquidation, dissolution, or winding-up of
the corporation, as such terms are used in this Paragraph 3, shall not be deemed
to be occasioned by or to include any merger of the corporation with or into one
or more corporations or other entities, any acquisition or exchange of the
outstanding shares of one or more classes or series of the corporation, or any
sale, lease, exchange, or other disposition of all or a part of the assets of
the corporation.

     B. PREFERRED STOCK

     1. Shares of the Preferred Stock may be issued from time to time in one or
more series, the shares of each series to have such designations, preferences,
limitations, and relative rights, including voting rights, as shall be stated
and expressed herein or in a resolution or resolutions providing for the issue
of such series adopted by the board of directors of the corporation. Each such
series of Preferred Stock shall be designated so as to distinguish the shares
thereof from the shares of all other series and classes. The board of directors
of the corporation is hereby expressly authorized, subject to the limitations
provided by law, to establish and designate series of the Preferred Stock, to
fix the number of shares constituting each series, and to fix the designations
and the preferences, limitations, and relative rights, including voting rights,
of the shares of each series and the variations of the relative rights and
preferences as between series, and to increase and to decrease the number of
shares constituting each series, provided that the board of directors may not
decrease the number of shares within a series to less than the number of shares
within such series that are then issued. The relative powers, rights,
preferences, and limitations may vary between and among series of Preferred
Stock in any and all respects so long as all shares of the same series are
identical in all respects, except that shares of any such series issued at
different times may have different dates from which dividends thereon cumulate.
The authority of the board of directors of the corporation with respect to each
series shall include, but shall not be limited to, the authority to determine
the following:

          (a) The designation of such series;


                                        2

          (b) The number of shares initially constituting such series;

          (c) The rate or rates and the times at which dividends on the shares
     of such series shall be paid, the periods in respect of which dividends are
     payable, the conditions upon such dividends, the relationship and
     preferences, if any, of such dividends to dividends payable on any other
     class or series of shares, whether or not such dividends shall be
     cumulative, partially cumulative, or noncumulative, if such dividends shall
     be cumulative or partially cumulative, the date or dates from and after
     which, and the amounts in which, they shall accumulate, whether such
     dividends shall be share dividends, cash or other dividends, or any
     combination thereof, and if such dividends shall include share dividends,
     whether such share dividends shall be payable in shares of the same or any
     other class or series of shares of the corporation (whether now or
     hereafter authorized), or any combination thereof, and the other terms and
     conditions, if any, applicable to dividends on shares of such series;

          (d) Whether or not the shares of such series shall be redeemable or
     subject to repurchase at the option of the corporation or the holder
     thereof or upon the happening of a specified event, if such shares shall be
     redeemable, the terms and conditions of such redemption, including but not
     limited to the date or dates upon or after which such shares shall be
     redeemable, the amount per share which shall be payable upon such
     redemption, which amount may vary under different conditions and at
     different redemption dates, and whether such amount shall be payable in
     cash, property, or rights, including securities of the corporation or
     another corporation;

          (e) The rights of the holders of shares of such series (which may vary
     depending upon the circumstances or nature of such liquidation,
     dissolution, or winding up) in the event of the voluntary or involuntary
     liquidation, dissolution, or winding up of the corporation and the
     relationship or preference, if any, of such rights to rights of holders of
     stock of any other class or series. A liquidation, dissolution, or winding
     up of the corporation, as such terms are used in this subparagraph (e),
     shall not be deemed to be occasioned by or to include any merger of the
     corporation with or into one or more corporations or other entities, any
     acquisition or exchange of the outstanding shares of one or more classes or
     series of the corporation, or any sale, lease, exchange, or other
     disposition of all or a part of the assets of the corporation;

          (f) Whether or not the shares of such series shall have voting powers
     and, if such shares shall have such voting


                                        3

     powers, the terms and conditions thereof, including, but not limited to,
     the right of the holders of such shares to vote as a separate class either
     alone or with the holders of shares of one or more other classes or series
     of stock and the right to have more (or less) than one vote per share;

          (g) Whether or not a sinking fund shall be provided for the redemption
     of the shares of such series and, if such a sinking fund shall be provided,
     the terms and conditions thereof;

          (h) Whether or not a purchase fund shall be provided for the shares of
     such series and, if such a purchase fund shall be provided, the terms and
     conditions thereof;

          (i) Whether or not the shares of such series, at the option of either
     the corporation or the holder or upon the happening of a specified event,
     shall be convertible into stock of any other class or series and, if such
     shares shall be so convertible, the terms and conditions of conversion,
     including, but not limited to, any provision for the adjustment of the
     conversion rate or the conversion price;

          (j) Whether or not the shares of such series, at the option of either
     the corporation or the holder or upon the happening of a specified event,
     shall be exchangeable for securities, indebtedness, or property of the

             STATEMENT OF DESIGNATIONS, PREFERENCES, LIMITATIONS AND
             RELATIVE RIGHTS OF SERIES A CONVERTIBLE PREFERRED STOCK

                         Pursuant to Article 2.13 of the
                         Texas Business Corporation Act

     The undersigned President of Gateway Technologies, Inc., a Texas
corporation (the "Corporation"), certifies that pursuant to authority granted to
and vested in the Board of Directors of the Corporation by the provisions of the
Articles of Incorporation of the Corporation, as amended, and in accordance with
the provisions of Article 2.13 of the Business Corporation Act of the State of
Texas, its Board of Directors on January 12, 1995, duly adopted the following
resolutions creating the Series A Convertible Preferred Stock:

     WHEREAS, the Board of Directors of the Corporation is authorized, within
the limitations and restrictions stated in the Articles of Incorporation of the
Corporation, as amended, to fix by resolution or resolutions the designation of
each series of stock and the preferences, limitations, and relative rights,
including voting rights, and qualifications, limitations, or restrictions
thereof, including, without limiting the generality of the foregoing, such
provisions as may be desired concerning voting, redemption, dividends,
dissolution, or the distribution of assets, conversion or exchange, and such
other subjects or matters as may be fixed by resolution or resolutions of the
Board of Directors under the Business Corporation Act of the State of Texas; and

     WHEREAS, it is the desire of the Board of Directors of the Corporation,
pursuant to its authority as aforesaid, to authorize and fix the terms of a
series of preferred stock and the number of shares constituting such series;

     NOW, THEREFORE, BE IT RESOLVED, that one series of preferred stock is
hereby authorized on the terms and with the provisions herein set forth:

     1. Designation, Number of Shares and Stated Value. The designation of the
series of preferred stock authorized by this resolution shall be "Series A
Convertible Preferred Stock," which shall consist of 30,000 shares of such
Series A Convertible Preferred Stock, $1.00 par value per share. As used herein,
"Stated Value" per share of Series A Convertible Preferred Stock shall be equal
to $20.00 plus all accumulated and unpaid dividends added thereto pursuant to
Section 2 hereof. Each share of Series A Convertible Preferred Stock shall be
validly issued, fully paid and nonassessable upon receipt by the Corporation of
legal consideration in an amount determined by the Board of Directors of the
Corporation to be at least equal to such Stated Value.

     2. Dividends

          (a) 6% Dividend. The holders of shares of Series A Convertible
Preferred Stock shall be entitled to receive, out of the funds of the
Corporation legally available therefor, if, as and when declared by the Board of
Directors, cash dividends at the rate of 6% per share

per annum, on the face value thereof, accruing from February 28, 1995, payable
quarterly on the last day of the months of February, May, August, and November
in each year, commencing May 31, 1995, except that if such date is a Saturday,
Sunday or legal holiday then such dividend shall be payable on the first
immediately preceding day which is not a Saturday, Sunday or legal holiday. Such
dividends shall be cumulative (whether or not in any quarterly dividend period
there shall be funds of the Corporation legally available for the payment of
such dividends), commencing on the date of original issue and shall be payable
for any period less than a full quarter on the basis of a year of 360 days with
equal 30 day months. Dividends shall be payable to holders of record, as they
appear on the stock books of the Corporation, on such record dates as may be
declared by the Board of Directors, not more than sixty (60) days nor less than
ten (10) days preceding the payment dates for such dividends. Dividends in
arrears may be declared and paid at any time, without reference to any regular
dividend payment date, to holders of record on such date, not exceeding sixty
(60) days preceding the payment date thereof, as may be fixed by the Board of
Directors of the Corporation. When dividends are not paid in full upon the
shares of the Series A Convertible Preferred Stock and any other preferred stock
ranking on a parity as to payment of dividends with the Series A Convertible
Preferred Stock ("Parity Stock"), all dividends declared upon shares of the
Series A Convertible Preferred Stock and any Parity Stock shall be declared pro
rata so that the amount of dividends declared per share on the Series A
Convertible Preferred Stock and such Parity Stock shall in all cases bear to
each other the same ratio that accumulated dividends per share on the shares of
the Series A Convertible Preferred Stock and such Parity Stock bear to each
other.

          (b) Certain Restrictions on Payment. So long as any shares of the
Series A Convertible Preferred Stock are outstanding and any dividends due and
payable on the Series A Convertible Preferred Stock are in arrears, the
Corporation shall not, without the prior written consent of a holder or the
holders of more than fifty per cent of the issued and outstanding shares of
Series A Convertible Preferred Stock, declare, pay or set apart for payment any
dividend on any of the Junior Securities (hereinafter defined) or make any
payment on account of, or set apart for payment money for a sinking or other
similar fund for, the purchase, redemption or other retirement of any of the
Junior Securities or any warrants, rights, calls or options exercisable for any
of the Junior Securities, or make any distribution in respect thereof, either
directly or indirectly, and whether in cash, obligations or shares of stock of
the Corporation or other property, and shall not permit any corporation or other
entity directly or indirectly controlled by the Corporation to redeem, purchase
or otherwise acquire any equity security (other than the shares of the
Corporation's common stock, par value $1.00 per share ("Common Stock"), into
which the Series A Convertible Preferred Stock is convertible) of the
Corporation (or any non-wholly owned subsidiary of the Corporation); provided,
however, that the Corporation shall be permitted to repurchase (i) shares of the
Common Stock of the Corporation held by employees, consultants, officers, or
directors pursuant to the terms of any restrictive stock purchase arrangements
under which the Corporation has the option or obligation to repurchase such
shares upon the occurrence of certain events such as termination of employment


                                        2

or failure to serve as a director and (ii) shares of the Series A Convertible
Preferred Stock pursuant to the terms of this Statement of Designations,
Preferences, Limitations and Relative Rights of Series A Convertible Preferred
Stock

     3. Liquidation Preference.

     In the event of any voluntary or involuntary liquidation, dissolution or
winding up of the affairs of the Corporation, the holders of shares of the
Series A Convertible Preferred Stock then outstanding shall be entitled to be
paid out of the assets of the Corporation available for distribution to its
stockholders an amount of cash equal to the greater of (a) the amount per share
that holders of Series A Convertible Preferred Stock would be entitled to
receive if all of their shares of Series A Convertible Preferred Stock were
converted into Common Stock at the time of such liquidation, dissolution or
winding up or (b) the Stated Value of the Series A Convertible Preferred Stock
at the time of such liquidation, dissolution or winding up, and no more, before
any payment shall be made or any assets distributed to the holders of any of the
Junior Securities; provided, however, that the holders of the outstanding shares
of Series A Convertible Preferred Stock shall not be entitled to receive such
liquidation payment until the liquidation payments on all outstanding shares of
any other stock of the Corporation having liquidation rights ranking prior to
the shares of Series A Convertible Preferred Stock shall have been paid in full.
If the assets of the Corporation are not sufficient to pay in full the
liquidation payments payable to the holders of outstanding shares of Series A
Convertible Preferred Stock and any outstanding shares of any other stock of the
Corporation having liquidation rights on parity with the shares of the Series A
Convertible Preferred Stock, then the holders of all such shares shall share
ratably in such distribution of assets in accordance with the amount which would
be payable on such distribution if the amounts to which the holders of
outstanding shares of Series A Convertible Preferred Stock and the holders of
outstanding shares of such other stock of the Corporation are entitled were paid
in full. A merger of or by the Corporation or sale of all or substantially all
assets of the Corporation shall not be deemed to be a liquidation, dissolution
or winding up of the Corporation.

     4. Ranking.

     The Series A Convertible Preferred Stock shall, with respect to dividend
rights and distribution of assets on liquidation, rank (a) junior to, or on
parity with, as the case may be, any other stock of the Corporation, the terms
of which shall specifically provide that such stock shall rank senior to, or on
parity with, as the case may be, the Series A Convertible Preferred Stock with
respect to dividend rights or distribution of assets on liquidation, and (b)
senior to any other stock of the Corporation, including the Common Stock (all of
such stock of the Corporation to which the Series A Convertible Preferred Stock
ranks prior, including the Common Stock, being referred to collectively for
purposes of this Agreement as the "Junior Securities")


                                        3

     5. Voting Rights. Except as otherwise required by the Corporation's
Articles of Incorporation (as amended), Bylaws, the Texas Business Corporation
Act or any other applicable law, the holders of the Series A Convertible
Preferred Stock shall not have any voting rights with respect to any matter.

     6. Take-along Rights. In the event there is a bona fide offer from a third
party to acquire more than fifty per cent of the then outstanding shares of
voting securities of the Corporation, or to acquire control of the Corporation
by other means, each holder of the Series A Convertible Preferred Stock shall
have the right to convert all but not less than all of his or her shares of
Series A Convertible Preferred Stock into Common Stock at the conversion rate of
one share of Common Stock for each share of Series A Convertible Preferred Stock
(the "Converted Shares") and require the Selling Shareholders (herein so called)
to condition their acceptance of the offer on the offeror's agreement
simultaneously (a) to acquire the same proportion of the Converted Shares on the
same terms and conditions applicable to the acquisition of the Selling
Shareholders' shares, and (b) to pay all accumulated dividends on the Series A
Convertible Preferred Stock then in arrears.

     7. Conversion Rights. On March 1, 1998, the holders of shares of Series A
Convertible Preferred Stock shall have conversion rights as follows:

          (a) Mandatory Conversion or Put Option. Each holder of the Series A
Convertible Preferred Stock shall, within 60 days of but no later than 10 days
before March 1, 1998, by written notice to the Secretary of the Corporation,
elect either (i) to convert all of his, her or its shares of Series A
Convertible Preferred Stock into the Corporation's Common Stock at the rate of
one share of Common Stock for each share of Series A Convertible Preferred Stock
(the "Conversion Option"), or (ii) to demand that the Corporation repurchase all
of his, her or its shares of Series A Convertible Preferred Stock at the Stated
Value per share (the "Redemption Option"), the election of either (i) or (ii)
above by the holder or holders of the Series A Convertible Preferred Stock being
mandatory and, once made as provided above, irrevocable. A holder of the Series
A Convertible Preferred Stock who does not provide the written election
described in the preceding sentence shall be deemed to have elected the
Conversion Option. The Corporation shall undertake to prepare, authorize and
issue all such Common Stock to be issued in connection with shares subject to
the Conversion Option and to arrange for the payment for the shares subject to
the Redemption Option, and shall cause such payment or conversion to be made at
the expense of the Corporation not later than March 15, 1998.

          (b) Taxes. The Corporation will pay any documentary stamp and similar
taxes (other than income taxes and ad valorem taxes) that may be payable in
respect to any issue or delivery of shares of Common Stock on conversion of the
Series A Convertible Preferred Stock pursuant hereto. The Corporation shall not,
however, be required to pay any tax which may be


                                        4

payable in respect to any transfer involved in the issue and delivery of shares
of Common Stock in a name other than that in which the Series A Convertible
Preferred Stock so converted was registered, and no such issue or delivery
shall be made unless and until the person requesting such issue or delivery has
paid to the Corporation the amount of any such tax, or has established, to the
satisfaction of the Corporation, that such tax has been paid. To the extent any
tax is payable upon redemption, such tax is the responsibility of the
shareholder.

     8. Notices of Record Date. The Corporation shall mail by first class mail
or recognized courier service to the holders of the Series A Convertible
Preferred Stock at their last known address shown on the stockbook of the
Corporation a notice in the event that the Corporation shall propose at any time
to do any of the following:

          (a) to declare any dividend or distribution upon the Common Stock or
the Series A Convertible Preferred Stock, whether in cash, property, stock or
securities, whether or not a regular cash dividend and whether or not out of
earnings or surplus;

          (b) to offer for subscription pro rata to the holders of any class or
series of its stock any additional shares of stock of any class or series or
other rights;

          (c) to effect any reclassification or recapitalization of the Common
Stock or the Series A Convertible Preferred Stock outstanding involving a change
in the Common Stock or the Series A Convertible Preferred Stock, respectively;
or

          (d) to merge or consolidate with or into any other corporation, or
sell, lease or convey all or substantially all its property or business, or to
liquidate, dissolve or wind up.

Notice of an event described in parts (b), (c), and (d) above shall be sent to
the holders of the Series A Convertible Preferred Stock at least twenty days
prior to the date on which a record shall be taken in connection with such
event.

     9. Amendment. Except as may otherwise be required by the laws of the State
of Texas, the provisions of this Statement may be amended or compliance by the
Corporation herewith waived only by the affirmative vote or written consent of a
holder or the holders of more than fifty percent of the issued and outstanding
shares of Series A Convertible Preferred Stock.

     IN WITNESS WHEREOF, the undersigned have executed this Statement on behalf
of the Corporation as of the 13th day of January 1995.
