WARRANT AGREEMENT

     THIS WARRANT AGREEMENT (the "Agreement"), dated as of September 1, 1996, is
made and entered into by and among Optel, Inc., a Delaware corporation (the
"Company"), and James A. Kofalt (the "Warrantholder"). This Agreement is being
executed in connection with the Separation and Consulting 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 1,360 (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, tranferred 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 pursuit 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






deliverer 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 of, 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 SECURITIES 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

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

                                       -2-





          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 writing
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
     August 31, 1999 (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 to 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 100
     Shares (subject to appropriate adjustment for any stock split
     recapitalization or similar event) for any Warrantholder (unless less than
     an aggregate of 100 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 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

                                       -3-




     not occur, then this Agreement will be terminated without further
     obligation by either party.

          (b) Payment by each Warrantholder of the aggregate Warrant Price due
     from him shall be made in cash or by immediately available funds, certified
     check or any combination thereof.

          (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 this
     Warrant, together with cash, as provided in Section 9 hereof, 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. Every transfer agent for the Common
Stock and other securities of the Company issuable upon the exercise of the
Warrants will be irrevocably authorized and directed at all times to reserve
such number of authorized shares and other securities as shall be requisite for
such purpose. The

                                       -4-



Company will keep a copy of this Agreement on file with every transfer agent for
the Common Stock and other securities of the Company issuable upon the exercise
of the Warrants. The Company will supply every such transfer agent with duly
executed stock and other certificates, as appropriate, for such purpose and will
provide or otherwise make available any cash which may be payable as provided in
Section 9 hereof. On or before taking any action that would cause an adjustment
pursuant to the terms of the Warrants resulting in an increase in the number of
shares of Common Stock deliverable upon such conversion or exercise above the
number thereof previously authorized, reserved and available therefor, the
Company shall take all such action so required for compliance with this Section.

     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
$984, subject to adjustment as provided in this Agreement.

     Section 8. Adjustments 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 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 three percent in the number of Shares
          then purchasable upon the exercise of the Warrants or, if the Warrants
          are not then exercisable, the number of Shares purchasable upon the
          exercise of the Warrants on the first date thereafter that the
          Warrants become exercisable; provided, however, that any adjustments
          which by reason of this subsection 8.1(b) are not required to be made
          immediately shall be carried forward and taken into account in any
          subsequent adjustment.

                                       -5-



               (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 numbers 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 propose 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 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 purchase or successor by merger, sale
     of assets or similar business combination to assume the obligations under
     this Agreement.

          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.

                                      -6-



     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
"IPO"), Fair Value of the 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.

     Section 10. No right as Stockholder; Notices to Warrantholder. 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.

                                      -7-



     Section 11. Securities laws; Restrictions on Transfer of Shares;
Registration Rights.

          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.


                   "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
                  PURCHASE OF THESE SECURITIES THAT RESTRICT
                  THEIR TRANSFER AND PROVIDE, FOR CERTAIN
                  VOTING AGREEMENTS AND RIGHTS OF FIRST
                  REFUSAL 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."

                                      -8-



          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 IPO 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:

               (i) Prior to entering into the Separation Agreement, the original
          Warrantholder was the Chairman of the Board of the Company and as of
          the date of this Agreement remained as a director 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's obligation to
          include the Shares in certain registration statements as set forth in
          the Warrant Agreement, 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, and in particular the
          Warrantholder has no current intention to resell the Shares under such
          registration statements nor would he have such intention if such
          registration statements were effective

                                      -9-



          as of the date of this representation. 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 represent 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, except as provided in this Agreement with respect to the
          sale of the Shares to third parties, 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 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 except as provided for in this
          Agreement with respect to the Shares.

               (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 two years 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

                                      -10-




          securities being sold during any three-month period not exceeding the
          specified limitations stated therein.

               (v) The Warrantholder further understands that at the item 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 requirement 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.

               (vii) the Warrantholder has had a reasonable opportunity to ask
          questions relating to the Company' 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 inquires. 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.

          (b) 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. Until such
     notice is

                                      -11-




     given, the transferee shall forfeit has right to exercise his registration
     rights hereunder. 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 IPO, 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.

          (c) Transferees Bound. Prior to any transfer of Shares (except a
     transfer registered under the Act or a transfer of Shares, occurring after
     an IPO, pursuant to Rule 144), the proposed transferee shall agree in
     writing with the Company to be bound by the terms of this Agreement
     (whether or not the Warrant has been exercised or otherwise outstanding)
     as if an original signatory hereto, and the proposed transferee must be
     able to and must deliver a certificate to the Company containing the
     representations and covenants as set forth in this subsection 11.1.

          (d) No Registration of Transferred Warrants. The Warrantholder is not
     entitled to any registration rights with respect to the transfer of the
     Warrants.

     11.3 Piggy-Back Registration Rights.

          (a) Registration Rights. Following the time of the exercise of a
     Warrant, the Holder of a Warrant Share thereby purchased shall be entitled
     to the "piggy-back" registration rights granted hereby. Except as otherwise
     provided in this Section 11.3, the registration rights granted hereby may
     be used one time only. If the Company shall determine to register any of
     its equity securities, either for its own account or the account of a
     security holder or holders, other than (i) a registration relating to
     employee benefit plans, or (ii) a registration relating to a transaction
     subject to Rule 145 promulgated under the Act, the company will.

               (i) promptly give to each Holder written notice thereof; and

               (ii) include in such registration (and any related qualification
          under blue sky laws or other compliance) the Registrable Securities
          specified in a written requests or requests, (subject to the
          limitation of Section 11.3(b) below made within ten (10) days after
          receipt of such written notice from the Company, by the Holder.

               Such notification will be kept confidential by the Holder. If the
          Holder desires to include in any such registration statement all or
          any part of the Registrable Securities held by him, the Holders shall,
          within ten (10) days after receipt of the above-described notice from
          the Company, so notify the Company in writing. Such notice shall state
          the intended method of disposition of the Registrable Securities by
          such Holder.

          (b) Underwriting. If the registration of which the Company gives
     notice is for a registered public offering involving an underwriting, the
     Company shall so advise the Holders as a part of the written notice given
     pursuant to subsection 11.3(a)(i). In such event the right of any Holders
     to registration pursuant to Section 11.3 shall be conditioned upon such
     Holders' participation in such underwriting, and the inclusion of
     Registrable Securities in the underwriting shall be limited to the extent
     provided therein. All Holders proposing to distribute their securities
     through such underwriting shall (together with the Company and the other
     holders distributing their securities through such underwriting) enter into
     an

                                      -14-




     underwriting agreements in customary form with the managing underwriter
     selected for such underwriting by the Company. Notwithstanding any other
     provision of this Section 11.3, if the managing underwriter determines that
     marketing factors require a limitation of the number of shares to be
     underwritten, the underwriter may limit the Registrable Securities to be
     included in such registration. In the event of a limitation (or
     elimination) on the number of shares to be included in a registration, then
     the Company shall so advise the Holders, and the number of shares of
     Registrable Securities that may be included in the registration and
     underwriting shall be allocated among each Holder and all other persons
     with registration rights that have requested that shares held by them be
     registered. Such allocation shall be in proportion, as nearly as
     practicable, to the respective number of shares of Common Stock requested
     to be registered by each Holder and by such other persons. To facilitate
     the allocation of shares in accordance with the above provisions, the
     Company may round the number of shares allocated to such Holder to the
     nearest 100 shares. If a holder disapproves of the terms of any such
     underwriting, he may elect to withdraw therefrom by written notice to the
     Company and the managing underwriter. Any securities excluded or withdrawn
     from such underwriting shall be withdrawn from such registration, and shall
     not be transferred in a public distribution except in accordance with the
     terms of subsection 11.4(f)(vi). In the event that any Registrable
     Securities of a Holder are not included in a registration as a result of
     the limitation or elimination imposed by this subsection 11.3(b) then such
     Holder shall be entitled to one additional piggy-back registration right on
     the same terms as are provided in this Agreement.

     11.4 Registration Matters

          (a) Right to Terminate Registration. The Company or any other Person
     initiating a registration shall have the right for any reason and without
     liability to any Holder to terminate, suspend or withdraw any registration
     initiated by it under this Section 11 prior to or after the effectiveness
     of such registration whether or not a Holder has elected to include
     securities in such registration; provided, that any termination, suspension
     or withdrawal of a registration prior to effectiveness of such registration
     statement or after effectiveness but prior to the expiration of the period
     described in subsection 11.4(c)(i) below shall not count as the Holder's
     piggy-back registration hereunder.

          (b) Expenses of Registration. All Registration Expenses incurred in
     connection with any registration, qualification or compliance pursuant to
     Section 11 shall be borne by the Company. All Selling Expenses relating to
     the securities registered by or on behalf of the Holders shall be borne by
     such Holders.

          (c) registration Procedures. In the case of the registration,
     qualification or compliance effected by the Company pursuant to this
     Agreement, the

                                      -15-




     Company will, upon reasonable request, inform each Holder whose Shares are
     included in the registration as to the status of such registration,
     qualification and compliance. Subject to Section 11.4(a) above, at its
     expense, the Company will:

               (i) use its reasonable best efforts to keep such registration and
          any qualification or compliance under state securities laws which the
          Company determines to obtain, effective until at least the 90 days
          (excluding any days for which sales may not be made pursuant to
          Section 11.4(d)) after the effective date of the registration or until
          the Holders have completed the distribution described in the
          registration statement relating thereto, whichever first occurs; and

               (ii) furnish such number of prospectuses and other documents
          incident thereto as the Holders from time to time may reasonably
          request.

          The period of time during which the Company is required hereunder to
     keep the Registration Statement effective is referred to herein as "the
     Registration Period." Notwithstanding anything to the contrary contained
     herein, at the Company's election the Company may cease to keep such
     registration, qualification or compliance effective with respect to a
     Holder's Registrable Securities , and the related registration rights of a
     Holder shall expire, at such time as the Holder may sell under Rule 144
     under the Act (or other exemption from registration acceptable to the
     Company) in a three-month period all Registrable securities than held by
     such Holder.

          (d) Delay of sales

               (i) Each Holder will cease all sales of Registrable Securities if
          the Company believes that the filing of a requested registration
          statement at the time it is requested, or the offering and sale of
          Registrable Securities pursuant thereto, (A) would adversely affect a
          pending or proposed public offering of the Company's securities, or a
          material acquisition, or a transaction or negotiations, discussions or
          pending proposals with respect thereto or (B) would adversely affect
          the business, financial condition or prospects of the Company in view
          of the disclosures which may be required or advisable thereby;
          provided, however, that the Company's right to cause cessation of
          sales hereunder may be exercised on only one occasion within any
          360-day period and in no event may cause cessation of sales hereunder
          for more than 90 days on such occasion.

               (ii) the Holders shall have no right to take any action to
          restrain, enjoin or otherwise delay any registration pursuant to this
          Section

                                      -16-




     11 as a result of any controversy that may arise with respect to the
     interpretation or implementation of this Agreement.

          (e) Indemnification.

               (i) The Company will indemnify each Holder, each of its officers,
          directors, employees, partners, each underwriter (if any) , legal
          counsel and accountants, and each person controlling such Holder
          within the meaning of Section 15 of the Act, with respect to which any
          registration, qualification or compliance has been effected pursuant
          to this Agreement, and each person who controls any underwriter within
          the meaning of Section 15 of the Act, against all expenses, claims
          losses, damages and liabilities (or action in respect thereof),
          including any of the foregoing incurred in settlement of any
          litigation, commenced or threatened, arising out of or based on any
          untrue statement (or alleged untrue statement) or a material fact
          contained in any registration statement, prospectus, offering circular
          or other document, or any amendment or supplement thereof, incident to
          any such registration, qualification or compliance, or based on any
          omission (or alleged omission) to state therein a material fact
          required to be stated therein or necessary to make the statements
          therein not misleading, and will reimburse each Holder, each of its
          officers, directors, employees, partners legal counsel and
          accountants, and each person controlling such holder, and each person
          who controls any such underwriter, for reasonable legal and any other
          expenses reasonably incurred in connection with investigating,
          preparing or defending any such claim, loss, damage, liability or
          action as incurred; provided, however, that the Company will not be
          liable in any such case to the extent that any untrue statement or
          omission or allegation thereof is made in reliance upon and in
          conformity with written information furnished to the Company by an
          instrument duly executed by or on behalf of such Holder and stated to
          be specifically for use in preparation of such registration statement,
          prospectus, offering circular or other document; and provided further
          that the Company will not be liable in any such case where the
          expense, claim, loss, damage or liability arises out of or is related
          to the failure of any Holder to comply with the covenants and
          agreement contained in this Agreement respecting sales of Registrable
          Securities; and provided further, that the indemnity with respect to
          any preliminary prospectus shall not inure to the benefit of any
          underwriter or seller of a security (or to the benefit of any person
          controlling such underwriter or seller) to the extent that any such
          claim, loss, damage or liability results from the fact that the
          definitive prospectus, as amended and supplemented, was not sent or
          delivered to the person asserting any such claims, losses, damages or
          liabilities at or prior to the written confirmation of the sale of
          Registrable Securities to such person and the untrue statement (or
          alleged untrue

                                      -17-




          statement) or omission (or alleged omission) of a material fact
          contained in a preliminary prospectus was corrected in the definitive
          prospectus, as amended or supplemented, provided that the Company
          delivered the definitive prospectus, as amended or supplemented, to,
          such underwriter or seller on a timely basis to permit such delivery
          or sending.

               (ii) Each Holder will, if Registrable Securities held by such
          Holder are included in the securities as to which such registration,
          qualification or compliance is being effected, indemnify the Company,
          each of it directors, officers, employees, partners, legal counsel and
          accountants, each underwriter, if any, and each person who controls
          the Company or such underwriter within the meaning of Section 15 of
          the Act, against all claims, losses, damages and liabilities (or
          actions in respect thereof), including any of the foregoing incurred
          in settlement of any litigation, commenced or threatened, arising out
          of or based on any untrue statement (or alleged untrue statement) of a
          material fact contained in any registration statement, prospectus,
          offering circular or other document, or any amendment or supplement
          thereof, incident to any such registration, qualification or
          compliance, or based on any omission (or alleged omission) to state
          therein a material fact required to be stated therein or necessary to
          make the statements therein not misleading, or any failure by each
          such Holder to comply with the covenants or agreements contained in
          this Agreement respecting the Registrable Securities and will
          reimburse the Company, such directors, officers, employees, partners,
          legal counsel and accountants for reasonable legal and any other
          expenses reasonably incurred in connection with investigating,
          preparing or defending any such claim, loss, damage, liability or
          action as incurred, in each case to the extent, but only to the
          extent, that such untrue statement or omission or allegation thereof
          is made in reliance upon and in conformity with written information
          furnished to the Company by an instrument duly executed by or on
          behalf of such Holder and stated to be specifically for use in
          preparation of such registration statement, prospectus, offering
          circular or other document; provided, however, that the indemnity with
          respect to any preliminary prospectus shall not inure to the person
          controlling such underwriter or seller) to the extent that such claim,
          loss, damage or liability results from the fact that the definitive
          prospectus, as amended and supplemented, was not sent or delivered to
          the person asserting any such claim, loss, damage or liability at or
          prior to the written confirmation of the sale of the Registrable
          Securities to such person and the untrue statement (or alleged untrue
          statement) or omission (or alleged omission) of a material fact
          contained in a preliminary prospectus was corrected in the definitive
          prospectus, as amended or supplemented, provided that the Company
          delivered the definitive prospectus, as amended or

                                      -18-




          supplemented, to, such underwriter or seller on a timely basis to
          permit such delivery or sending.

               (iii) Each party entitled to indemnification under this
          subsection 11.4(e) the "Indemnified Party") shall give notice to the
          party required to provide indemnification (the "Indemnifying Party")
          promptly after such Indemnified Party has actual knowledge of any
          claim as to which indemnity may be sought, and shall permit the
          Indemnifying Party to assume the defense of any such claim or any
          litigation resulting therefrom, provided that counsel for the
          Indemnifying Party, which shall conduct the defense of such claim or
          litigation, shall be approved by the Indemnified Party (whose approval
          shall not unreasonably be withheld), and the Indemnified Party may
          participate in such defense at such party's expense, and provided
          further that the failure of any Indemnified Party to give notice as
          provided herein shall not relieve the Indemnifying Party of its
          obligations under this Agreement, unless such failure is prejudicial
          to the Indemnifying Party in defending such claim or litigation. An
          Indemnifying Party shall not be liable for any settlement of an action
          or claim effected without its written consent (which consent will not
          be unreasonably withheld).

               (iv) If the indemnification provided for in this subsection
          11.4(e) is held by a court of competent jurisdiction to be unavailable
          to an Indemnified Party with respect to any loss, liability, claim,
          damage or expense referred to therein, then the Indemnifying Party, in
          lieu of indemnifying such Indemnified Party thereunder, shall
          contribute to the amount paid or payable by such Indemnified Party as
          a result of such loss, liability, claim, damage or expense (i) in such
          proportion as is appropriate to reflect the relative benefits received
          by the Company on the one hand and all Holders offering shares in the
          offering (the "Selling Shareholders") on the other from the offering
          of the Company securities, or (ii) if the allocation provided by
          clause (i) above is not permitted by applicable law, in such
          proportion as is appropriate to reflect not only the relative benefits
          referred to in clause (i) above but also the relative fault of the
          Company on the one hand and the Selling Shareholders on the other in
          connection with the statements or omissions which resulted in such
          losses, claims, damages or liabilities, as well as any other relevant
          equitable considerations. The relative benefits received by the
          Company on the one hand, and the Selling Shareholders on the other
          shall be the net proceeds from the offering (before deducting
          expenses) received by the Company on the one hand and the Selling
          Shareholders on the other. the relative fault of the Company on the
          one hand and the Selling Shareholder on the other shall be determined
          by reference to, among other things, whether the untrue or alleged
          untrue statement of material fact or the omission or alleged omission
          to state a

                                      -19-




          material fact relates to information supplied by the Company on the
          one hand and/or the Selling Shareholders and the parties' relevant
          intent, knowledge, access to information and opportunity to correct or
          prevent such statement or omission. The Company and the Selling
          Shareholders agree that it would not be just and equitable if
          contribution pursuant to this subsection 11.4(e) were based solely
          upon the number of entities from whom contribution was requested or by
          any other method of allocation which does not take account of the
          equitable considerations referred to above in this subsection 11.4(e).

          (f) Covenants of Holder

               (i) Each Holder agrees that, upon receipt of any notice from the
          Company of the happening of any event requiring the preparation of a
          supplement or amendment to a prospectus relating to Registrable
          Securities so that, as thereafter delivered to such Holder, such
          prospectus will not contain untrue statement of a material fact or
          omit to state any material fact required to be stated therein or
          necessary to make the statements therein not misleading, each holder
          will forthwith discontinue disposition of Registrable Securities
          pursuant to the registration statements contemplated by Section 11
          until its receipt of copies of the supplemented or amended prospectus
          from the Company and, if so directed by the company, each Holder shall
          deliver to the Company all copies, other than permanent file copies
          then in such Holders' possession, of the prospectus covering such
          Registrable Securities current at the time of receipt of such notice.

               (ii) Each Holder agrees to notify the company, at any time when a
          prospectus relating to the registration statement contemplated by
          Section 11, is required to be delivered by it under the Act, of the
          occurrence of any event relating to such Holder which requires the
          preparation of a supplement or amendment to such Holder which requires
          the preparation of a supplement or amendment to such prospectus so
          that, as thereafter delivered to the purchasers of Registrable
          Securities, such prospectus will not contain an untrue statement of a
          material fact or omit to state any material fact required to be stated
          therein or necessary to make the statements therein not misleading
          relating to such Holder, and such Holder shall promptly make available
          to the Company the information to enable the Company to prepare any
          such supplement or amendment. Each Holder also agrees that, upon
          delivery of any notice by it to the Company of the happening of any
          event of the kind described in the next preceding sentence of this
          subsection, such Holder will forthwith discontinue disposition of
          Registrable Securities pursuant to such registration statement until
          its receipt of the copies of the supplemental or amended prospectus
          contemplated by this subsection, which the Company shall promptly make
          available to such Holder and, if so directed by the Company, such
          Holder shall deliver to the Company all

                                      -20-




          copies, other than permanent file copies then in such Holder's
          possession, of the prospectus covering such Registrable Securities
          current at the time of receipt of such notice.

               (iii) Each Holder shall furnish to the Company such information
          regarding such Holder and the distribution proposed by such Holder as
          the Company may request in writing or as shall be required in
          connection with any registration, qualification or compliance referred
          to in this Section 11.

               (iv) Each Holder hereby covenants with the Company (1) not to
          make any sale of the Shares without effectively causing the prospectus
          delivery requirements under the Act to be satisfied, and (2) if such
          Shares are to be sold by any method or in any transaction other than
          on a national securities exchange, in the over-the-counter market, on
          the Nasdaq National Market, in privately negotiated transactions, or
          in a combination of such method, to notify the Company at least five
          business days prior to the date on which such Holder first offers to
          sell any such Shares. Each Holder agrees not to take any action with
          respect to any distribution deemed to be made pursuant to such
          registration statement that constitutes a violation of Rule 10(b)-6
          under the Exchange Act or any other applicable rule, regulation or
          law.

               (v) Each Holder acknowledges and agrees that in the event of
          sales under a shelf registration statement under subsection 11.4
          hereof the Registrable Securities sold pursuant to such registration
          statement are not transferable on the books of the Company unless the
          stock certificate submitted to the transfer agent evidencing such
          Shares is accompanied by a certificate reasonably satisfactory to the
          Company to the effect that (A) the Registrable Securities have been
          sold in accordance with such registration statements and (B) the
          requirement of delivering a current prospectus has been satisfied.

               (vi) Whether prior to or after the time the registration rights
          contemplated by Section 11 have terminated with respect to the
          Holders, each Holder agrees that it will not effect any sale,
          disposition or other transfer of Shares or Registrable Securities
          (whether or not its Shares or Registrable Securities are included in
          the registration) except pursuant to such registration statement, for
          a period of 180 days (or for such longer period as each executive
          officer of the Company personally agrees to be bound in a similar
          lock-up agreement) from the effective date of a registration statement
          in the case of an IPO and for a period 120 days (or for such longer
          period as each executive officer of the Company personally agrees to
          be bound in a similar

                                      -21-




          lock-up agreement) from the effective date of a registration statement
          in the case of a secondary public offering; provided, however, that as
          to each such registration, the Holder's obligations shall be limited
          to be no greater than obligations of all executive officers and
          directors of the company pursuant to similar lock-up agreements. Each
          Holder agrees not to take any action with respect to any distribution
          deemed to be made pursuant to such registration statement that
          constitutes a violation of Rule 10(b)-6 under the Exchange Act or any
          other applicable rule, regulation or law.

          (g) Transfer of Registration Rights. The rights to cause the Company
     to include Registrable Securities in a Registration Statement granted to
     the Holder by the Company under Section 11 may be assigned only to a
     transferee of the Warrants that receives the Warrants in a transfer made in
     accordance with this Agreement and who gives the notices required under
     this Agreement. The rights of the Holder with respect to Registrable
     Securities as set out herein shall not be transferable to any other Person,
     and any attempted transfer shall cause all rights of such Holder therein to
     be forfeited.

          (h) Waivers and Amendments. With the written consent of the Company
     and the Majority Holders, any provision of Sections 11.3 and 11.4 may be
     waived (either generally or in a particular instance, either retroactively
     or prospectively and either for a specified period of time or indefinitely)
     or amended. Upon the effectuation of each such waiver or amendment, the
     Company shall promptly give written notice thereof to each Holder, if any,
     who have not previously received notice thereof or consented thereto in
     writing.

          (i) Termination of Registration Rights. Notwithstanding any thing to
     the contrary contained herein, at the Company's election, the registration
     rights of any Holder shall expire, and the Company may cease to keep any
     registration, qualification or compliance effective with respect to any
     Registrable Securities, and at such time as such Holder may sell under Rule
     144 under the Act in a three-month period all Registrable Securities then
     held by such Holder.

     Section 12. Notices. Any notice pursuant to this Agreement by the Company
or by the Warrantholder or a Holder of Shares shall be in writing and shall be
deemed to have been duly given if delivered or mailed by certified or registered
first class mail, return receipt requested and postage prepaid:

     A. Kofalt, 50209 Manly, Chapel Hill, North Carolina 27514.

          (b) If to the Company, addressed to it at Optel, Inc., 1111 West
     Mockingbird Lane, Dallas, Texas 75247, Attention: Chief Executive Officer
     (with a copy to the General Counsel of the Company at the same address).

Each party may from time to time change the address to which notices to it are
to be delivered or mailed hereunder by notice in accordance herewith to the
other party.

     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 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 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.
James A. Kofalt violates paragraphs 5 or 6 of the Separation Agreement.

     Section 19.Stockholders Agreement; Rights of First Refusal. In the event
that the Warrant is exercised prior to an IPO, then the Warrantholder hereby
agrees that he shall thereupon (and without any further action by the
Warrantholder) become bound by the terms of the

                                      -23-




Stockholders Agreement dated as of December 22, 1994 (the "Stockholders
Agreement") among the Company VPC Corporation, Vanguard Communications, L. P.
and Vanguard Communications, Inc. Any transfer by the Warrantholder of any
Shares shall be subject to sections 6.4(a) and (b) and sections 6.6(a),(e) and
(f) of the Stockholders Agreement as if the term "Vanguard" in such sections
(and only in such sections) referred to the Warrantholder. The Warrantholder
shall be subject to the restrictions and obligations of the Stockholders
Agreement in favor of the Company and other stockholders, but shall not be
entitled to the benefits arising therefrom other than the rights to receive
compensation upon the exercise of any purchase rights by another stockholder or
third party.

     If the Shareholders Agreement is terminated prior to an IPO, all shares
will nonetheless be (without any further action by the Warrantholder) subject to
the right of first refusal on the same terms as Sections 6.4(a) and (b) of such
Shareholders Agreement (the "Stockholder Provisions") which are incorporated
herein and made a part hereof as fully as though set forth herein at length. In
such event, the Stockholder Provisions shall be enforceable and effective in
accordance with the terms of this Agreement (with such changes as may be
necessary or appropriate to (i) conform the names of the designated parties in
such sections to the names of the parties hereto and (ii) to provide that
defined terms used in such sections have the same meanings herein as in the
Stockholders Agreement as the case may be) irrespective of the time of
termination of the term of the Stockholders Agreement. This second paragraph of
Section 19 shall be effective until the date of the closing an IPO.

     Upon the request of the Company, the Warrantholder will also enter a
written agreement pursuant to which the Warrantholder further evidences his
agreements as set forth in this Section.

     Section 20. Gender. The gender of words used in this Agreement shall be
construed to include whichever may be appropriate under any particular
circumstances of the masculine, feminine or neuter genders.

                                      -24-

executed, all as of the day and year first above written.
