EXHIBIT 4.7

                               WARRANT AGREEMENT

          THIS WARRANT AGREEMENT (the "Agreement"), dated as of July 11, 1997,
is made and entered into by and among Optel, Inc., a Delaware corporation (the
"Company"), and Rory O. Cole (the "Warrantholder"). This Agreement is being
executed in connection with the Separation Agreement of even date herewith by
and between the Company and the Warrantholder (the "Separation Agreement").

          The Company agrees, in consideration of the Warrantholder's entering
into the Separation Agreement, to issue and sell, and the Warrantholder, by
entering into the Separation Agreement, will receive warrants, as hereinafter
described (the "Warrants"), to purchase up to 9,406.36 shares (the "Shares"), of
the Company's Class A Common Stock, par value $.01 per share (the "Common
Stock"). The Purchase and sale of the Warrants shall occur contemporaneous with,
and is subject to the closing of the Separation Agreement.

          In consideration of the foregoing and for the purpose of defining the
terms and provisions of the Warrants and the respective rights and obligations
thereunder, the Company and the Warrantholder, for value received, hereby agree
as follows:

          Section 1.     Transferability and Form of Warrants.
                         ------------------------------------

                  1.1.   Registration. The Warrants shall be numbered and shall
                         ------------                                          
     be registered on the books of the Company when issued.

                  1.2.   Certain Limitations on Transfer. The Warrants and the
                         -------------------------------               
     Shares shall not be sold, assigned, transferred or pledged except upon the
     conditions specified in this Agreement. The Warrants may not be transferred
     voluntarily and may only be transferred upon death, either by will or
     intestacy law, or otherwise by operation of law and only then if such
     transfer is made in accordance with the terms of this Agreement. The
     Warrantholder will cause any proposed purchaser, assignee, transferee or
     pledgee of the Warrants or the Shares, except for transferees in
     dispositions of Shares that are pursuant to an effective registration
     statement under the Act (as defined herein) or transferees in dispositions
     of Shares occurring after an IPO (as defined herein) pursuant to Rule 144
     under the Securities Act of 1933, as amended (the "Act"), to agree to take
     and hold such securities subject to the provisions and upon the conditions
     specified in this Agreement. The Warrants may be divided or combined, upon
     request to the Company by the Warrantholder into a certificate or
     certificates representing the right to purchase the same aggregate number
     of Shares. Unless the context indicates otherwise, the term "Warrantholder"
     shall include any transferee or transferees of the Warrants or the Shares
     that is required to be bound by the terms hereof, and the term "Warrants"
     shall include any and all warrants outstanding pursuant to this Agreement,
     including those evidenced by a certificate or certificates issued upon
     division,

 
     exchange, transfer or substitution pursuant to this Agreement. The Company
     may refuse to effect the transfer of the Warrants until the transferee of
     the Warrants executes a counterpart to this Agreement and it shall be a
     condition to any transfer that the transferee execute and deliver to the
     Company a separate certificate that contains the representations and
     covenants in Section 11 hereof. The Warrantholder, by his receipt of a
     Warrant Certificate, agrees to be bound by and to comply with the terms of
     this Agreement. The Warrantholder represents and agrees that the Warrant
     (and Shares if the Warrant is exercised) is purchased only for investment,
     for the Warrantholder's own account and without any present intention to
     sell, or with a view to distribution ot the Warrant or Shares.

                  1.3.   Form of Warrants. The text of the Warrants and of the
                         ----------------                                     
     form of election to purchase Shares shall be substantially as set forth in
     Exhibit A attached hereto. The number of Shares issuable upon exercise of
     the Warrants is subject to adjustment upon the occurrence of certain
     events, all as hereinafter provided. The Warrants shall be executed on
     behalf of the Company by its President or by a Vice President, attested to
     by its Secretary or an Assistant Secretary. A Warrant bearing the signature
     of an individual who was at any time the proper officer of the Company
     shall bind the Company, notwithstanding that such individual shall have
     ceased to hold such office prior to the delivery of such Warrant or did not
     hold such office on the date of this Agreement.

                  The Warrants shall be dated as of the date of signature
     thereof by the Company either upon initial issuance or upon division,
     exchange, transfer or substitution.

                  1.4.   Legend on Warrants. Each Warrant Certificate shall bear
                         ------------------                                     
     the following legend:

                         (a)  "THE WARRANTS REPRESENTED BY THIS CERTIFICATE HAVE
               BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER
               THE SECRRITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES
               LAW. SUCH WARRANTS MAY NOT BE SOLD OR TRANSFERRED UNLESS
               REGISTERED OR QUALIFIED UNDER SAID ACT AND APPLICABLE STATE
               SECURITIES LAWS AND UNLESS THE COMPANY RECEIVES AN OPINION OF
               COUNSEL FOR THE HOLDER REASONABLY ACCEPTABLE TO THE COMPANY
               STATING THAT SUCH SALE OR TRANSFER IS EXEMPT FROM THE
               REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SAID ACT.
               COPIES OF THE WARRANT AGREEMENT COVERING THE PURCHASE OF THESE
               WARRANTS AND IMPOSING VARIOUS REQUIREMENTS, INCLUDING WITHOUT
               LIMITATION PROVISIONS RESTRICTING THEIR TRANSFER, MAY BE OBTAINED
               AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER OF RECORD OF
               THIS CERTIFICATE TO THE SECRETARY OF THE CORPORATION AT THE
               PRINCIPAL EXECUTIVE OFFICES OF THE CORPORATION."; and

                                      -2-

 
                         (b)  any legend required by applicable state securities
               law.

               Any certificate issued at any time in exchange or substitution
     for any Warrant certificate bearing such legends shall also bear the above
     legends unless, in the opinion of the Company's counsel, the securities
     represented thereby need no longer be subject to such restrictions. The
     Warrantholder consents to the Company's making a notation on his records
     and giving instructions to any registrar or transfer agent of the Warrants
     in order to implement the restrictions on transfer established in this
     Agreement.

          Section 2.     Exchange of Warrant Certificate. Any Warrant
                         -------------------------------              
certificate may be exchanged for another certificate or certificates entitling
the Warrantholder to purchase a like aggregate number of Shares as the
certificate or certificates surrendered then entitled such Warrantholder to
purchase. Any Warrantholder desiring to exchange a Warrant certificate shall
make such request in wriring delivered to the Company, and shall surrender,
properly endorsed, with signatures guaranteed, the certificate evidencing the
Warrant to be so exchanged. Thereupon, the Company shall execute and deliver to
the person entitled thereto a new Warrant certificate or certificates as so
requested.

          Section 3.     Term of Warrants: Exercise of Warrants.
                         -------------------------------------- 

                         (a)  Subject to the terms of this Agreement, the
          Warrantholder shall have the right, at any time and from time to time
          during the period commencing on the Waiver Effective Date (as such
          term is defined in the Separation Agreement), and ending at 5:00 p.m.
          Dallas, Texas time, on July 11, 2002 (the "Termination Date"), to
          purchase from the Company up to the number of fully paid and
          nonassessable Shares to which the Warrantholder may at the time be
          entitled tS purchase pursuant to this Agreement, upon surrender to the
          Company, at its principal office, of the certificate evidencing the
          Warrants to be exercised, together with the purchase form on the
          reverse thereof duly filled in and signed, with signatures guaranteed,
          and upon payment to the Company of the Warrant Price (as defined in
          and determined in accordance with the provisions of this Section 3 and
          Sections 7 and 8 hereof), but in no event for less than 1,000 Shares
          (subject to appropriate adjustment for any stock split,
          recapitalization or similar event) for any Warrantholder (unless less
          than an aggregate of 1,000 Shares (subject to appropriate adjustment
          for any stock split, recapitalization or similar event) are then
          purchasable under all outstanding Warrants held by a Warrantholder.
          The Warrants shall be exercisable, at the election of the
          Warrantholder, either in full or from time to time (subject to the
          other provisions in this Section) in part and, in the event of a
          certificate evidencing the Warrants is exercised in respect of less
          than all of the Shares specified therein at any time prior to the
          Termination Date, a new certificate evidencing the remaining portion
          of the Warrants held by the Warrantholder will be issued by the
          Company. It shall be a condition to exercise that the Warrantholder

                                      -3-

 
          execute and deliver a certificate to the Company containing the
          representations and covenants set forth in Section 11 hereof which
          certificate must state that such representations and warranties are
          true and correct. If the Waiver Effective Date does not occur, then
          this Agreement will be terminated without further obligation by
          either parry.

                         (b)  Payment by each Warrantholder of the aggregate
          Warrant Price due from him shall be made

                              (i)  in cash or by immediately available funds,
               check, or any combination thereof; or

                             (ii)  by means of a "Cashless Exercise". In the
               event of a Cashless Exercise, the Warrantholder shall exchange
               its Warrant for such number of shares of Common Stock determined
               by multiplying the number of Shares by a fraction, the numerator
               of which shall be the difference between the then-current market
               price per share of Common Stock and the Warrant Price, and the
               denominator of which shall be the then-current market price per
               share of Common Stock. For purposes of this Section the "then
               current market price per share of Common Stock" at any date shall
               be deemed to be (a) if the Common Stock is not traded on an
               established securities market, the fair market value of the
               Common Stock as determined in good faith by the Board of
               Directors of the Company, which determination shall be conclusive
               and binding on the Warrantholder, and (b) if the Common Stock is
               traded on an established securities market, the average of the
               daily closing prices for 20 consecutive trading days commencing
               30 trading days before such date. The closing price for each day
               shall be the last sales price regular way or, in case no such
               reported sales take place on such day, the average of the last
               reported bid and asked prices regular way, in either case on the
               principal national securities exchange on which the Common Stock
               is admitted to trading or listed or, if not listed or admitted to
               trading on any such exchange, on NASDAQ, or if closing prices are
               not quoted on NASDAQ, the representative closing bid price as
               reported by NASDAQ or by another similar organization if NASDAQ
               is no longer reporting such information.

                         (c)  Upon such surrender of the Warrants and payment of
          such Warrant Price as aforesaid, the Company shall issue and cause to
          be delivered to or upon the written order of the exercising
          Warrantholder and in such name or names as the exercising
          Warrantholder may designate (which in no way shall limit the transfer
          restrictions hereunder) a certificate or certificates for the number
          of full Shares so purchased upon the exercise of his Warrant, together
          with cash, as provided

                                      -4-

 
          in Section 9 hereot, in respect of any fractional Shares otherwise
          issuable upon such surrender. Such certificate or certificates shall
          be deemed to have been issued and any person so designated to be named
          therein shall be deemed to have become a holder of record of such
          securities as of the date of surrender of the Warrants and payment of
          the Warrant Price, as aforesaid, notwithstanding that the certificate
          or certificates representing such securities shall not actually have
          been delivered or that the stock transfer books of the Company shall
          then be closed.

          Section 4.     Payment of Taxes. The Company will pay all documentary
                         ----------------                                      
stamp taxes, if any, attributable to the initial issuance of the Warrants or the
securities comprising the Shares; provided, however, the Company shall not be
required to pay any tax which may be payable in respect of any secondary
transfer of the Warrants or of the securities comprising the Shares.

          Section 5.     Mutilated or Missing Warrants. In case the certificate
                         -----------------------------             
or certificates evidencing the Warrants shall be mutilated, lost, stolen or
destroyed, the Company shall, at the request of the Warrantholder, issue and
deliver in exchange and substitution for and upon cancellation of the mutilated
certificate or certificates, or in lieu of and substitution for the certificate
or certificates lost, stolen or destroyed, a new Warrant certificate or
certificates of like tenor and representing an equivalent right or interest, but
only upon receipt of evidence satisfactory to the Company of such loss, theft or
destruction of such Warrant and a bond of indemnity, if requested, also
satisfactory in form and amount at the applicant's cost. Applicants for such
substitute Warrant certificate shall also comply with such other reasonable
regulations and pay such other reasonable charges as the Company may prescribe.

          Section 6.     Reservation of Shares. There has been reserved, and the
                         ---------------------                                  
Company shall at all times keep reserved so long as the Warrants remain
outstanding, out of its authorized Common Stock, such number of shares of Common
Stock as shall be subject to purchase under the Warrants.

          Section 7.     Warrant Price. The price per Share at which Shares
                         -------------                                  
shall be purchasable upon the exercise of the Warrants (the "Warrant Price")
shall be $74.42, subject to adjustment as provided in this Agreement.

          Section 8.     Adjustment of Number of Shares and Warrant Price. The
                         ------------------------------------------------
number and kind of securities purchasable upon the exercise of the Warrants and
the Warrant Price shall be subject to adjustment from time to time upon the
happening of certain events, as follows:

                  8.1.   Adjustments. The number of Shares purchasable upon the
                         -----------                                           
     exercise of the Warrants shall be subject to adjustment as follows:

                         (a)  In case the Company shall (i) pay a dividend in
          Common Stock or make a distribution in Common Stock, (ii) subdivide
          its outstanding Common Stock, (iii) combine its outstanding Common
          Stock into a smaller number

                                     -5- 

 
          of shares of Common Stock or (iv) issue by reclassification of its
          Common Stock other securities of the Company, the number of Shares
          purchasable upon exercise of the Warrants immediately prior thereto
          shall be adjusted so that the Warrantholder shall be entitled to
          receive the kind and number of Shares or other securities of the
          Company which it would have owned or would have been entitled to
          receive immediately after the happening of any of the events described
          above had the Warrants been exercised immediately prior to the
          happening of such event or any record date with respect thereto. Any
          adjustment made pursuant to this subsection 8.1(a) shall become
          effective immediately after the effective date of such event
          retroactive to the record date, if any, for such event.

                         (b)  No adjustment in the number of Shares purchasable
          pursuant to the Warrants shall be required unless such adjustment
          would require an increase or decrease of at least five percent in the
          number of Shares then purchasable upon the exercise of the Warrants;
          provided, however, that any adjustments which by reason of this
          subsection 8.l(b) are not required to be made immediately shall be
          carried forward and taken into account in any subsequent adjustment.

                         (c)  Whenever the number of Shares purchasable upon the
          exercise of the Warrant is adjusted, as herein provided, the Warrant
          Price payable upon exercise of the Warrant shall be adjusted by
          multiplying such Warrant Price immediately prior to such adjustment by
          a fraction, of which the numerator shall be the number of Shares
          purchasable upon the exercise of the Warrant immediately prior to such
          adjustment and of which the denominator shall be the number of Shares
          so purchasable immediately thereafter.

                         (d)  Whenever the number of Shares purchasable upon the
          exercise of the Warrants is adjusted as herein provided, the Company
          shall cause to be promptly mailed to the Warrantholder by first class
          mail, postage prepaid, notice of such adjustment and a certificate of
          the chief financial officer of the Company setting forth the number of
          Shares purchasable upon the exercise of the Warrants after such
          adjustment, a brief statement of the facts requiring such adjustment
          and the computation by which such adjustment was made.

                         (e)  For the purpose of this Section 8.1, the term
          "Common Stock" shall mean (i) the class of stock designated as the
          Class A Common Stock of the Company at the date of this Agreement or
          (ii) any other class of stock resulting from successive change or
          reclassifications of such Common Stock consisting solely of changes in
          par value, or from par value to no par value, or from no par value to
          par value. In the event that at any time, as a result of an adjustment
          made pursuant to this Section 8, the Warrantholder shall become
          entitled to purchase any securities of the Company other than Common
          Stock, thereafter the number of such other securities so purchasable
          upon exercise of the Warrants shall be subject to adjustment

                                      -6-

 
          from time to time in a manner and on terms as nearly equivalent as
          practicable to the provisions with respect to the Shares contained in
          this Section 8.

               8.2.  No Adjustment for Certain Matters. During the term of
                     ---------------------------------                    
     the Warrants or upon the exercise of the Warrants, no adjustment shall be
     made (i) in respect of any dividends or distributions, except as
     specifically provided in subsection 8.1(a) or (ii) in respect of the
     consummation of any dissolution, liquidation or winding up of the Company
     or a consolidation, merger, share exchange or similar business combination
     or sale of its property, assets and business as an entirety or
     substantially as an entirety. Without limiting the generality of the
     foregoing, the Company shall have no obligation to cause any purchaser or
     successor by merger, sale of assets or similar business combination to
     assume the obligations under this Agreement. If, however, at any time prior
     to the expiration of the Warrants and prior to their exercise, a merger or
     similar business combination shall be proposed, and the purchaser shall not
     have agreed to assume the obligations under this Agreement, then the
     Company shall give notice in writing of such event to the Warrantholder, as
     provided in Section 12 hereof, promptly prior to the date fixed as a record
     date or the date of closing the transfer books for the determination of the
     stockholders entitled to vote on such proposed merger or business
     combination in order to provide the Warrantholder an opportunity to
     exercise the Warrant. Without limiting any claim for damages that a
     Warrantholder might have for breach by the Company of its obligations under
     the immediately preceding sentence, failure to mail or receive such notice
     or any defect therein shall not affect the validity of any action taken
     with respect to the merger or business combination.

               8.3.  Statement on Warrant Certificates. Irrespective of any
                     ---------------------------------                     
     adjustments in the number of securities issuable upon exercise of Warrants,
     Warrant certificates theretofore or thereafter issued may continue to
     express the same number of securities as are stated in the similar Warrant
     certificates initially issuable pursuant to this Agreement. However, the
     Company may, at any time in its sole discretion (which shall be
     conclusive), make any change in the form of Warrant certificate that it may
     deem appropriate and that does not affect the substance thereof; and any
     Warrant certificate thereafter issued, whether upon registration or
     transfer of, or in exchange or substitution for, an outstanding Warrant
     certificate, may be in the form so changed.

          Section 9. Fractional Interests: Fair Value. The Company shall not be
                     --------------------------------                          
required to issue fractional Shares on the exercise of the Warrants. If any
fraction of a Share would, except for the provisions of this Section 9, be
issuable on the exercise of the Warrants (or specified portion thereof), the
Company shall pay an amount in cash equal to the then Fair Value of the Common
Stock multiplied by such fraction. As used herein, the term "Fair Value" of the
Common Stock or other Securities or other property shall mean the fair value as
determined in good faith by the Company's Board of Directors, which
determination shall be binding upon the Warrantholder; provided, however, that
after the closing date of an initial public offering of Common Stock pursuant to
a registration statement filed with and declared effective by the SEC (an
"IP0"), Fair Value of the

                                      -7-

 
Common Stock for any day shall mean the last sales price, regular way, on such
day or, in case no such sale takes place on such day, the average of the closing
bid and asked prices, regular way, on such day, in either case as reported in
the principal transaction reporting system with respect to securities listed or
admitted to trading on the principal national securities exchange on which such
security is listed or admitted to trading, or, if such security is not listed or
admitted to trading on any national securities exchange but sales price
information is reported for such security, as reported by The Nasdaq Stock
Market ("Nasdaq") National Market or such other self-regulatory organization or
registered securities information processor (as such terms are used under the
Securities Exchange Act of 1934, as amended (the "Exchange Act")) that then
reports information concerning such security, or, if sales price information is
not so reported, the average of the high bid and low asked prices in the over-
the-counter market on such day, as reported by Nasdaq or such other entity, or,
if on such day such security is not quoted by any such entity, the average of
the closing bid and asked prices as furnished by a professional market maker
making a market in such security selected by the Board of Directors of the
Company. If on such day no market maker is making a market in such security, the
fair value of such security on such day as determined in good faith by the Board
of Directors of the Company shall be used and such determination shall be
conclusive and binding on the Warrantholder and his transferees.

                        ---------------------------------------------------- 
Nothing contained in this Agreement or in the Warrants shall be construed as
conferring upon the Warrantholder or his transferees any rights as a stockholder
of the Company, including the right to vote, receive dividends, call meetings,
consent or receive notices as a stockholder in respect of any meeting of
stockholders for the election of directors of the Company or any other matter or
imposing any fiduciary or other duty on the Company, its officers or directors,
in favor of the Warrantholder, all of which rights and duties are expressly
disclaimed and waived by the Warrantholder.

               11.1.

                        (a)   Compliance with Securities Act. The Warrantholder
                              ------------------------------  
          agrees that this Warrant and the related Shares (each of the Warrant
          and the Shares being referred to herein as a "Security" and together,
          "Securities") are being acquired for investment and that such
          Warrantholder will not purchase, offer, sell or otherwise dispose of
          any of the Securities except under circumstances which will not result
          in a violation of the Act. in order to exercise this Warrant, the
          Warrantholder must be able to confirm and shall confirm in writing, by
          executing a certificate to be supplied by the Company, all of the
          representations and other covenants contained in this Agreement,
          including that the Securities so purchased are being acquired for
          investment and not with a view toward distribution or resale. The
          Securities (unless registered under the Act) shall be stamped or
          imprinted with, in addition to any other appropriate or required
          legend, a legend in substantially the following form:

                                      -8-

 
                     "THE SECURITIES EVIDENCED HEREBY HAVE NOT
                     BEEN REGISTERED UNDER THE SECURITIES ACT OF
                     1933, AS AMENDED, OR ANY STATE SECURITIES
                     LAWS. SUCH SECURITIES MAY NOT BE SOLD OR
                     TRANSFERRED UNLESS REGISTERED OR QUALIFIED
                     UNDER SAID ACT AND APPLICABLE STATE
                     SECURITIES LAWS OR UNLESS THE CORPORATION
                     RECEIVES AN OPINION OF COUNSEL FOR THE
                     HOLDER, REASONABLY SATISFACTORY TO THE
                     CORPORATION, STATING THAT SUCH SALE OR
                     TRANSFER IS EXEMPT FROM THE REGISTRATION AND
                     PROSPECTUS DELIVERY REQUIREMENTS OF SAID
                     ACT. COPIES OF THE AGREEMENT COVERING THE

                     OF THIS CERTIFICATE TO THE SECRETARY OF THE
                     CORPORATION AT THE PRINCIPAL EXECUTIVE
                     OFFICES OF THE CORPORATION."

                     Any certificate for Shares issued at any time in exchange
          or substitution for any certificate bearing such legends (except a new
          certificate issued to a transferee upon completion of a public
          distribution pursuant to a registration statement under the Act or
          upon completion of a sale occurring after an IP0 under Rule 144 under
          the Act of the securities represented thereby) shall also bear the
          above legends unless, in the opinion of the Company's counsel, the
          securities represented thereby need no longer be subject to such
          restrictions. The Warrantholder consents to the Company making a
          notation on his records and giving instructions to any registrar or
          transfer agent of the Common Stock in order to implement the
          restrictions on transfer established in this Agreement.

                     In addition, the Warrantholder specifically represents to
          the Company both at the time of initial purchase of the Warrant and at
          those future times as specified herein:

                                      -9-

 
                         (i)  Prior to entering into the Separation Agreement,
                the original Warrantholder was the Chief Operating Officer of
                the Company. The Warrantholder has experience in analyzing and
                investing in companies like the Company and is capable of
                evaluating the merits and risks of an investment in the Company
                and has the capacity to protect his own interests. The
                Warrantholder is an "Accredited Investor" as that term is
                defined in Rule 501(a) promulgated under the Act. The
                Warrantholder is aware of the Company's business affairs and
                financial condition, and has acquired information about the
                Company sufficient to reach an informed and knowledgeable
                decision to acquire the Securities. The Warrantholder is
                acquiring the Securities for his own account for investment
                purposes only not as a nominee or agent and not with a view to,
                or for the resale in connection with, any "distribution" thereof
                for purposes of the Act. The Warrantholder is acquiring the
                Securities for investment for his own account, not as a nominee
                or agent, and not with a view to, or for resale in connection
                with, any distribution thereof. The Warrantholder acknowledges
                the Company has no obligation to include the Shares in any
                registration statements, the effectiveness of which registration
                statements may be required for the resale of the Shares. Without
                limiting the generality of the preceding sentences of this
                Section, the Warrantholder has not offered or sold any portion
                of the Securities to be acquired by such Warrantholder and has
                no present intention of reselling or otherwise disposing of any
                portion of such Securities either currently or after the passage
                of a fixed or determinable period of time or upon the occurrence
                or nonoccurrence of any predetermined event or circumstance. The
                Warrantholder understands that investment in the Securities is
                subject to a high degree of risk. The Warrantholder can bear the
                economic risk of his investment, including the full loss of his
                investment, and by reason of his business or financial
                experience or the business or financial experience of his
                professional advisors has the capacity to evaluate the merits
                and risks of his investment and protect his own interest in
                connection with the purchase of the Securities. The
                Warrantholder represents that he does not have any contract,
                undertaking, agreement or arrangement with any person to sell,
                transfer or grant participation to such person or to any third
                person, with respect to any of the Securities. If other than an
                individual, the Warrantholder also represents he has not been
                organized for the purpose of acquiring the Securities. The
                Warrantholder's purchase is not and will not be part of a plan
                or scheme to evade the registration requirements of the Act.

                        (ii)  The Warrantholder understands that the Securities
                have not been and will not be registered under the Act or any
                applicable state securities law in reliance upon a specific
                exemption therefrom, which exemption depends upon, among other
                things, the bona fide nature of the Warrantholder's investment
                intent as expressed herein and the accuracy of the

                                      -10-

 
                Warrantholder's representations as expressed herein and the
                Warrantholder will furnish the Company with such additional
                information as is reasonably requested by the Company in
                connection with such exemption.

                        (iii) The Warrantholder further understands that the
                Securities must be held indefinitely unless subsequently
                registered under the Act and any applicable state securities
                laws, or unless exemptions from registration are otherwise
                available. Moreover, the Warrantholder understands that the
                Company is under no obligation to and does not expect to
                register the Securities.

                        (iv)  The Warrantholder is aware of the provisions of
                Rule 144, promulgated under the Act, which, in substance, permit
                limited public resale of "restricted securities" acquired,
                directly or indirectly, from the issuer thereof (or from an
                affiliate of such issuer), subject to the satisfaction of
                certain conditions, if applicable, including, among other
                things: the availability of certain public information about the
                Company; the resale occurring not less than one year after the
                party has purchased and paid for the securities to be sold; the
                sale being made through a broker in an unsolicited "broker's
                transaction" or in transactions directly with a market maker (as
                said term is defined under the Exchange Act); and the amount of
                securities being sold during any three-month period not
                exceeding the specified limitations stated therein.

                        (v)   The Warrantholder further understands that at the
                time he wishes to sell the Securities, it is possible that there
                will be no public market upon which to make such a sale, and
                that, even if such a public market then exists, the Company may
                not be satisfying the current public information requirements of
                Rule 144, and that, in such event, the Warrantholder may be
                precluded from selling the Securities under Rule 144 even if the
                minimum holding period had been satisfied.

                        (vi)  The Warrantholder further understands that in the
                event all of the requirements of Rule 144 are not satisfied,
                registration under the Act or compliance with registration
                exemption will be required; and that, notwithstanding the fact
                that Rule 144 is not exclusive, the Staff of the SEC has
                expressed its opinion that persons proposing to sell private
                placement securities other than in a registered offering and
                otherwise than pursuant to Rule 144 will have a substantial
                burden of proof in establishing that an exemption from
                registration is available for such offers or sales, and that
                such persons and their respective brokers who participate in
                such actions do so at their own risk.

                                      -11-

 
                         (vii)   The Warrantholder has had a reasonable
                opportunity to ask questions relating to the Company's business,
                management and financial affairs with the Company's management,
                customers and other parties, and the Warrantholder has received
                satisfactory responses to the Warrantholder's inquiries. The
                Warrantholder is not, and has not been within the ninety (90)
                days prior to the closing date of the purchase of the
                Securities, a broker or dealer of securities. To the best of his
                knowledge, (i) the Warrantholder was contacted regarding the
                sale of the Securities by a person or entity with whom the
                Warrantholder had a prior relationship and (ii) no securities
                were offered or sold to him by means of any form of general
                solicitation or general advertising, and in connection therewith
                the Warrantholder: did not (A) receive or review any
                advertisement, article, notice or other communication published
                in a newspaper or magazine or similar media or broadcast over
                television or radio, whether closed circuit or generally
                available; or (B) attend any seminar, meeting or industry
                investor conference whose attendees were invited by any general
                solicitation or general advertising.

          11.2  Disposition of Securities. There shall be no transfer of
                ------------------------- 
Warrants except for transfer at death as set forth in Section 1.2. The
transferee any Warrants must give notice to the Company of such transfer. With
respect to any offer, sale or other disposition of any Securities that are not
registered under the Act, the Warrantholder hereof agrees to give written notice
to the Company prior thereto, describing briefly the manner thereof together
with a written opinion of such Warrantholder's counsel to the effect that such
offer, sale or other disposition may be effected without registration or
qualification (under the Act as then in effect or any federal or state law then
in effect) of such Securities and indicating whether or not under the Act,
certificates for the Securities in question to be sold or otherwise disposed of
require any restrictive legend as to applicable restrictions on transferability
in order to ensure compliance with such law. Such opinion and such counsel must
be satisfactory to the Company in its reasonable judgment and such opinion
shall state that it may be relied upon by counsel to the Company, and any stock
exchange or transfer agent. Promptly upon receiving such written notice and
satisfactory opinion, if so requested, the Company shall notify such
Warrantholder that such Warrantholder may sell or otherwise dispose of such
Securities, all in accordance with the terms of the notice delivered to the
Company. If a determination has been made pursuant to this subsection (b) that
the opinion of counsel for the Warrantholder is not satisfactory to the Company,
the Company shall so notify the Warrantholder promptly after such determination
has been made and shall specify in detail the legal analysis supporting any such
conclusion. Each certificate representing the Securities thus transferred
(except a transfer registered under the Act or a transfer of Shares, occurring
after an IP0, pursuant to Rule 144) shall bear a legend as to the applicable
restrictions on transferability in order to ensure compliance with such laws,
unless in the aforesaid opinion of counsel for the Warrantholder, such legend is
not required in order to ensure compliance with such laws. The Company may issue
stop transfer instructions to its transfer agent in connection with such
restrictions. Notwithstanding the

                                      -12-

 
foregoing provisions of this Section 11.2, the Warrantholder agrees that
transfers may further be subject to Section 11.3 and Appendix I.

          11.3  Restrictions on Transfer and Repurchase and Sale Rights. The
                -------------------------------------------------------     
Warrantholder agrees that, in the event the Warrant is exercised prior to an
IPO, the Warrantholder will be subject to the terms and provisions of Appendix I
attached hereto and made a part hereof, which imposes restrictions on the
transfer of the Shares acquired upon exercise of the Warrant. The Warrantholder
further agrees that, in the event the Warrant is exercised prior to the
occurrence of an IPO, the Company may require as a condition to the exercise of
the Warrant that the Warrantholder furnish the Company with the written consent
of the Warrantholder's spouse (if any), or that any transferee of the Warrant
pursuant to Section 1.2 furnish written consent, to be bound by the terms and
conditions of Appendix I attached hereto, and such consent shall be furnished on
such form as the Company shall prescribe. Certificates representing the Shares
issued pursuant to the exercise of the Warrant will bear all legends required by
law and necessary to effectuate the revisions of this Agreement. The Company may
place a "stop transfer" order against the Shares issued pursuant to the exercise
of this Warrant until all restrictions and conditions set forth in Appendix I
attached hereto and the legends referred to in this Section 11.3 have been
complied with.

          11.4  No Registration Rights. The Warrantholder is not entitled to
                ----------------------                                      
any registration rights with respect to the transfer of the Warrants or with
respect to Shares acquired upon exercise of the Warrants.

          Section 12.  Notices. Any notice pursuant to this Agreement by the
                       -------

          at the same address).

Each party may from time to time change the address to which notices to it are

other parry.

          Section 13.  Successors. All the covenants and provisions of this
                       ----------                                          
Agreement by or for the benefit of the Company, the Warrantholder or the Holder
of Shares shall bind and inure to the benefit of their respective successors and
assigns hereunder.

          Section 14.  Applicable Law. This Agreement shall be deemed to be a

contract made under the laws of the State of Texas and for all purposes shall be
construed in

                                      -13-

 
accordance with the laws of said State applicable to contracts made and to be
performed entirely within such state.

          Section 15.  Benefits of this Agreement. Nothing in this Agreement
                       --------------------------            
shall be construed to give to any person or corporation other than the Company,
the Warrantholder and the Holders of Shares any legal or equitable right, remedy
or claim under this Agreement. This Agreement shall be for the sole and
exclusive benefit of the Company, the Warrantholder and the Holders of Shares.

          Section 16.  Counterparts. This Agreement may be executed in any

number of counterparts each of which shall be deemed an original, but all of
which shall constitute one and the same instrument.

          Section 17.  Amendment. Except as expressly provided herein, neither
                       ---------                                              
this Agreement nor any term hereof may be amended, waived, discharged or
terminated other than by a written instrument signed by the party against whom
enforcement of any such amendment, waiver, discharge or termination is sought;
provided, however, that any provisions hereof may be amended, waived, discharged
or terminated upon the written consent of the Company and the Warrantholder
having the right to acquire by virtue of holding the Warrants at least 50% of
the Shares which are then issuable upon exercise of the then outstanding
Warrants.

          Section 18.  Termination of Company Obligations. Notwithstanding any
                       ----------------------------------                     
other provision of this Agreement, all rights (but not the obligations) of any
Warrantholder (including without limitation, both any successor to the original
Warrantholder and any Holder of Shares) shall terminate and all obligations (but
not all rights) of the Company shall terminate upon the first date that Mr. Rory

                                  APPENDIX I

        RESTRICTIONS ON TRANSFER OF SHARES AND PURCHASE AND SALE RIGHTS


          Shares subject to the foregoing Warrant Agreement (the "Agreement")
acquired upon exercise of the Warrant may be Transferred (as defined below) only
after compliance with the specific limitations on the Transfer of Shares set
forth in the Agreement and in this Appendix I, including those with respect to
certain rights of first refusal granted to the Company (Paragraphs 4 and 5
below), restrictions upon Transfer imposed by applicable state or federal
securities laws, and certain required undertakings of the transferee (Paragraph
3 below). All Transfers of Shares not meeting the conditions set forth in this
Appendix I are expressly prohibited; provided, however, that the provisions of
this Appendix I will terminate upon the earlier of (i) the occurrence of an IPO,
or (ii) September 30, 2002. This Appendix I constitutes a part of the Agreement.

          1.   DEFINITIONS: All capitalized terms herein shall have the meanings
ascribed to them in the Agreement unless otherwise defined herein:

          (a)  "FAIR MARKET VALUE" means the fair market value of the Shares as
     determined in good faith by the Board of Directors of the Company. The
     determination of the Board of Directors shall be conclusive and binding on
     all persons.

          (b)  "INVOLUNTARY TRANSFER" means a Transfer that occurs pursuant to
     any of the following: an assignment of Shares for the benefit of creditors
     of the Warrantholder; a Transfer by operation of law, including, without
     limitation, a Transfer by will or under the laws of descent and
     distribution; an execution of judgment against Shares or the acquisition of
     record or beneficial ownership of Shares by a lender or creditor; a
     Transfer pursuant to any decree of divorce, dissolution, or separate
     maintenance, any property settlement, any separation agreement, or any
     other agreement with a spouse under which a part or all of any Shares is
     Transferred or awarded to the spouse of the Warrantholder or is required to
     be sold; or a Transfer resulting from the filing of the Warrantholder of a
     petition for relief or the filing of an involuntary petition against the
     Warrantholder, under the bankruptcy laws of the United States or of any
     other nation.

          (c)  "OFFERED PRICE" has the meaning ascribed thereto in Paragraph
               4(b).

          (d)  "OFFEROR" has the meaning ascribed thereto in Paragraph 4(a).

          (e)  "SHAREHOLDER NOTICE OF OFFER" has the meaning ascribed thereto in
     Paragraph 4(b).

 
          (f)  "SHAREHOLDER NOTICE OF TRANSFER" has the meaning ascribed thereto
     in Paragraph 5(b).

          (g)  "TRANSFER," with respect to Shares, includes, without limitation,
     a voluntary or involuntary sale, assignment, transfer, conveyance, pledge,
     hypothecation, encumbrance, disposal, loan, gift, attachment, or levy of
     such Shares.

          (h)  "TRANSFEREE NOTICE" has the meaning ascribed thereto in Paragraph
     5(b).

          (i)  "VOLUNTARY TRANSFER" means any Transfer other than an Involuntary
     Transfer.

          2.   EFFECT OR PROHIBITED TRANSFER: Any prohibited Transfer of Shares,
whether a Voluntary Transfer or an Involuntary Transfer, is void and of no
effect. Should such a Transfer purport to occur, the Company may refuse to carry
out the Transfer on its books, attempt to set aside the Transfer, enforce any
undertaking or right under the Agreement or this Appendix I, or exercise any
other legal or equitable remedy.

          3.   REQUIRED UNDERTAKINGS: Any Transfer that would otherwise be
permitted under the terms of the Agreement or this Appendix I is prohibited
unless the transferee executes such documents as the Company may reasonably
require to ensure that the Company's rights are adequately protected with
respect to the Shares so transferred. Such agreements may include, without
limitation, the transferee's agreement to be bound by all of the terms of the
Agreement or this Appendix I, as if he or she or it were the original
Warrantholder. Without limiting the generality of any other provision contained
herein, it is the intent of this paragraph that the Company's rights if waived
or otherwise not exercised in respect of a Transfer to a transferee shall
nonetheless continue with respect to any subsequent Transfers by such
transferee.

          4.   COMPANY'S RIGHT OF FIRST REFUSAL RELATED TO THIRD PARTY OFFER:

          (a)  SCOPE OF RIGHT: If Shares are Transferred or are proposed to be
               --------------                                                 
     Transferred incident to a bona fide offer from a third party (the
     "Offeror"), the Company will have the right (but not the obligation) to
     purchase Shares on the terms and conditions set out in this Paragraph 4.
     This right does not extend to a Third Party Offer made if the Warrantholder
     has no intention of transferring the Shares. The Company's rights under
     this Paragraph 4 are assignable by the Company and will terminate upon the
     earlier of (i) the occurrence of an IPO, or (ii) September 30, 2002,
     whether or not previously assigned. The right of first refusal under this
     Paragraph 4 will be exercisable in whole or in part as to any particular
     Transfer or proposed Transfer of Shares.

          (b) Mechanics and Notice: The transferor of any Shares subject to this
              --------------------                                              
     Paragraph 4 will provide to the Company a notice of proposed Transfer (the
     "Shareholder Notice of Offer") stating: the number of Shares that the
     transferor
     
                                      -2-

 
     proposes to Transfer and the transferor's bona fide intention to Transfer
     such Shares; the name and address of the transferor, the Offeror, and the
     original Warrantholder of the Shares (if other than the transferor); the
     manner and the date of such proposed Transfer; and the bona fide cash price
     and/or other consideration (and the fair market value thereof as estimated
     in good faith by the transferor) per share of Shares, if any, that the
     Offeror offered to pay for such Shares (the "Offered Price").

               The Company (or its assignee) may exercise its right of first
     refusal under this Paragraph 4 at any time not more than 60 days after the
     Company has received the Shareholder Notice of Offer with respect to such
     Shares. The Company (or its assignee) will exercise its right, if at all,
     by informing the transferor and Offeror in writing of the Company's (or its
     assignee's) intention to do so, in a notice that specifies a closing date
     that is no more than 30 days (or such later date as the Offeror may have
     offered) after the later of (i) receipt of the Shareholder Notice of Offer
     or (ii) determination of fair market value of the Shares. Additionally, if
     the Company disagrees with the transferor's estimate of the fair market
     value of any noncash consideration, the Board of Directors shall determine
     the Fair Market Value, and the Offered Price will be adjusted accordingly.

          (c)  EXERCISE PRICE: In exercising its repurchase rights under this
               --------------
     Paragraph 4, the Company (or its assignee) will pay in cash upon repurchase
     a price equal to the Offered Price, subject to an appropriate adjustment as
     determined by the Board of Directors to take into account the risk of
     nonpayment or deferral of any installment payments that may have been
     contained in the Offeror's offer.

          5.   COMPANY'S RIGHT OF FIRST REFUSAL UNRELATED TO THIRD PARTY OFFER:

          (a)  SCOPE OF RIGHT: If Shares are Transferred or are proposed to be
               --------------                                                 
     Transferred other than incident to a bona fide third parry offer or other
     than as expressly permitted under the Agreement, the Company will have the
     right (but not the obligation) to purchase Shares on the terms and
     conditions set forth in this Paragraph 5. The Company's rights under this
     Paragraph 5 will apply to any proposed or actual Voluntary Transfer or
     Involuntary Transfer other than those subject to Paragraph 4. The Company's
     rights under this Paragraph 5 are assignable by the Company and will
     terminate upon the earlier of (i) the occurrence of an IPO, or (ii)
     September 30, 2002, whether or not previously assigned. The right of first
     refusal under this Paragraph 5 will be exercisable in whole or in part as
     to any particular Transfer or proposed Transfer of Shares.

          (b)  MECHANICS AND NOTICE: The transferor of any Shares subject to
               -------------------- 
     this Paragraph 5 will (whether such Transfer is a Voluntary Transfer or an
     Involuntary Transfer) provide to the Company a notice of proposed Transfer
     (the "Shareholder Notice of Transfer") stating: the number of Shares that
     the transferor proposes to Transfer; the names and addresses of the
     transferor, the transferee or proposed transferee, and the original
     Warrantholder of the Shares (if other than the transferor);

                                      -3-

 
     and the circumstances, manner and date of such proposed Transfer (including
     information concerning the consideration involved). In the event of an
     Involuntary Transfer, the person obtaining the Shares promptly will notify
     the Secretary of the Company of such Involuntary Transfer and provide the
     information required in the Shareholder Notice of Transfer (the "Transferee
     Notice").

          The Company (or its assignee) may exercise its right of first refusal
     under this Paragraph 5 at any time during the 60-day period after (i) the
     Company has received either the Shareholder Notice of Transfer or the
     Transferee Notice with respect to such Shares or, if later (ii) the date
     that is 9 months after the death of the Warrantholder (if the Transfer was
     an Involuntary Transfer due to death). The Company (or its assignee) will
     exercise its right, if at all, by informing the transferor and transferee
     in writing of the Company's (or its assignee's) intention to do so, in a
     notice that specifies a closing date that is no more than 30 days after the
     later of (i) receipt of the Shareholder Notice of Transfer or the
     Transferee Notice, whichever is applicable, or (ii) the determination of
     Fair Market Value of the Shares, or (iii) one year after the death of the
     Warrantholder (if the Transfer was an Involuntary Transfer due to death).

          (c)  EXERCISE PRICE: In exercising its repurchase rights under this
               --------------
     Paragraph 5, the Company (or its assignee) will pay in cash upon repurchase
     a price equal to the Fair Market Value of the Shares that are Transferred
     or are proposed to be Transferred, as of the date of the Shareholder Notice
     of Transfer or the Transferee Notice.

          6.   OPTION TO PURCHASE AND SELL THE SHARES:

          (a)  SCOPE OF RIGHT: If on July 11, 2002 the Company has not
               --------------
     consummated an IPO, (i) the Company will have the right but not the
     obligation) to purchase all of the Shares (the "Company's Call Right"), and
     (ii) the Warrantholder will have the right but not the obligation) to sell
     all of the Shares to the Company (the "Warrantholder's Put Right"). The
     rights under this Paragraph 6 are assignable in whole or in part by the
     Company and the Warrantholder and will terminate on September 30, 2002, if
     not earlier terminated due to the occurrence of an IPO. The purchase option
     under this Paragraph 6 will be exercisable on an all-or-nothing basis as to
     any particular holder of Shares.

          (b)  MECHANICS AND NOTICE:
               -------------------- 

               (i)  The Company's Call Right Mechanics. The Company (or its
                    ---------------------------------- 
          assignee) will provide to any holder of Shares a notice of proposed
          purchase (the "Company's Purchase Notice") stating that it wishes to
          exercise its option to purchase all of the Shares owned by that
          holder; the Fair Market Value per Share and aggregate purchase price
          based thereon; and the proposed closing date of such purchase

                                      -4-

 
          which must be at least 30 but not more than 90 days from the date the
          Company's Purchase Notice was delivered to the holder of Shares. The
          Shares will be purchased on that date.

               (ii) The Warrantholder's Put Right Mechanics. The Warrantholder
                    ---------------------------------------
          (or his assignee) will provide to the Company (or its assignee) a
          notice of intent to sell (the "Put Notice"), stating that the
          Warrantholder wishes to exercise the option to sell the Shares, and
          upon receipt of the Put Notice the Company will furnish the
          Warrantholder (or his assignee) a notice of the Fair Market Value per
          Share and the aggregate purchase price based thereon; and the proposed
          closing date of such purchase which must be at least 30 but not more
          than 90 days from the date the Company's notice was delivered to the
          Warrantholder (or his assignee). The Shares will be purchased on that
          date if the Warrantholder furnishes the Company with a written
          acceptance at least 10 days before the proposed closing date.
          Notwithstanding the foregoing, however, if any repurchase due to a Put
          Notice requires the consent of the Company's lenders or investors and
          such consent is not given or if the repurchase would otherwise violate
          any covenant by which the Company is bound, then the repurchase shall
          occur at such later date as approved by the lenders or investors or as
          would not violate such covenant at a price determined pursuant to
          clause (c) below.

          (c)  EXERCISE PRICE: Upon a sale of the Shares under this Paragraph 6,
               -------------- 
     the Company (or its assignee) will pay in immediately available funds upon
     purchase the aggregate cash price equal to the Fair Market Value of the
     Shares purchased. In the event the repurchase due to a Put Notice has been
     delayed due to the failure to obtain the required consent of the Company's
     lenders or investors or due to the restrictions imposed by any covenant,
     then the purchase price for the Shares purchased shall be the Fair Market
     Value of the Shares on the date of the Put Notice plus interest accrued
     from the date of the Put Notice at an annual rate equal to the "prime rate"
     as reported in the Money Rates section of The Wall Street Journal on the
     first day reported after the date of the Put Notice.

          7.  MATTERS OF GENERAL APPLICABILITY: All closings shall take place at
the Company's (or its assignees) principal executive offices. If the consent or
approval of any governmental entity is necessary for the purchase of Shares
under the Agreement or if the expiration of any waiting period following the
giving of any notice to a governmental entity is required before such purchase
may be effected, the date of closing shall be extended to such date not more
than 10 days after the date on which such consent or approval is obtained or
notice period expired. At such closing the transferor of the Shares shall
assign, or cause to be assigned to the extent any of its rights in its Shares is
then held by another person, to the Company (or its assignee) all right, title
and interest in and to the Shares, free and clear of all liens. The transferor

          8.  ESCROW: For purposes of facilitating the enforcement of the
restrictions on Transfer set forth in the Agreement and this Appendix I, the
Board of Directors may, at its discretion, require any holder of Shares to
deliver the certificate(s) for such Shares with a stock power executed by him or
her and by his or her spouse (if required for Transfer), in blank, to the
Secretary of the Company or his or her designee, to hold said certificate(s) and
stock power(s) in escrow and to take all such actions and to effectuate all such
Transfers and/or releases as are in accordance with the terms of the Agreement
and this Appendix I. The certificates may be held in escrow so long as the
Shares are subject to a right of first refusal under the Agreement and this
Appendix I. The escrow holder will not be liable to the Warrantholder (or to any
other party) for any actions or omissions unless the escrow holder is grossly
negligent relative thereto. The escrow holder may rely upon any letter, notice,
or other document executed by any signature purported to be genuine.
