ITEM 5. OTHER EVENTS.


         On April 11, 2000, ZixIt Corporation (the "Registrant") entered into a
Common Stock and Warrant Purchase Agreement with H. Wayne Huizenga and his
affiliates and assigns (collectively, the "Investors"). Pursuant to the
agreement:

o   the Investors will invest $44 million in the Registrant

o   the Registrant will issue to the Investors: (1) 916,667 shares of the
    Registrant's common stock, $0.01 par value per share (the "Common Stock"),
    (2) ten-year warrants to purchase 916,667 shares of Common Stock at $57.60
    per share, and (3) four-year warrants to purchase 1,222,223 shares of Common
    Stock at $12.00 per share, which will be reallocated options Mr. Cook will
    surrender to the Registrant as described below. These four-year warrants are
    not exercisable until one year following the closing of the transaction.
    (The warrants noted in (2) and (3) are collectively referred to herein as
    the "Warrants.")

         In connection with the transaction, David P. Cook, the Registrant's
chairman and chief executive officer, will voluntarily surrender to the
Registrant 1,222,223 of his personal options to acquire shares of Common
Stock, for reallocation to the Investors (in the form of the four-year
warrants described in (3) above). The original exercise price for the Cook
options surrendered and reallocated to the Investors was $7.00 per share.
Following the transaction, Mr. Cook will retain options to purchase
approximately 2.5 million shares of Common Stock.

         Under the agreement, Mr. Huizenga will be elected to the Registrant's
Board of Directors and appointed Vice Chairman of the Board of Directors. The
consummation of the transaction is subject to approval by the Registrant's Board
of Directors and other customary conditions. The transaction is expected to
close within two weeks.

         The Investors will pay for the Common Stock and Warrants by delivering
secured personal, recourse promissory notes in the principal amount of their
respective shares of the purchase price, which promissory notes are payable in
three equal installments on May 1, 2000, June 30, 2000 and September 1, 2000
(the "Notes"). The Notes do not bear interest and are secured by security
interests in and pledges of the securities being purchased pursuant to a Stock
Pledge and Security Agreement. The Stock Pledge and Security Agreement provides
for the release of one-third of the pledged shares as principal installments
are paid under the Notes.

         Under the terms of a Registration Rights Agreement, the Registrant will
agree to use its best efforts to register by June 1, 2000 the resale of the
shares of Common Stock sold and the shares of Common Stock issuable upon the
exercise of the Warrants. This registration statement is expected to be a "shelf
registration statement" pursuant to which the Investors would be entitled to
resell their shares of Common Stock from time-to-time. If the Registrant fails
to effect this registration for any reason, the Investors have two "demand"
registration rights. In addition, if the Registrant fails to effect this
registration, the Investors will have certain "piggyback" or incidental
registration rights in the event of a registered offering of shares of Common
Stock by the Registrant or other shareholders of the Registrant.

                           sold pursuant to an exemption from registration
                           contained in the Securities Act based in part upon

                           contained in this Agreement. Purchaser hereby
                           represents and warrants to the Corporation as
                           follows:

                           4.4.1 Economic Risk. The Purchaser has substantial
                           experience in evaluating and investing in private

                           similar to the Corporation such that the Purchaser is
                           capable of evaluating the merits and risks of an
                           investment in the Corporation. The Purchaser
                           understands that: (1) the investment contemplated by

                           this investment indefinitely unless and until the
                           Shares or the Warrant Shares, which will constitute
                           "restricted securities" within the meaning of Rule
                           144 under the Securities Act, are registered pursuant
                           to the Securities Act, or an exemption from
                           registration is available. The Purchaser also
                           understands that there is no assurance that any
                           exemption from registration under the Securities Act
                           will be available and that, even if available, such
                           exemption may not allow such Purchaser to transfer
                           all or any portion of the Shares or the Warrant
                           Shares. Each Purchaser agrees that, until the
                           Corporation has caused the registration of the Shares
                           or the Warrant Shares under the Securities Act of

                           legend to the foregoing effect, which legend will be
                           as follows:

                           The shares represented by this certificate have been
                           acquired solely for investment purposes and have not
                           been registered under the Securities Act of 1933, as
                           amended, or the securities laws of any state. The
                           shares may not be sold, transferred, assigned or
                           otherwise disposed of unless and until such shares
                           are first registered under the Securities Act of
                           1933, all

                           Corporation that such registration is not required or
                           (ii) an opinion of counsel reasonably acceptable to
                           the Corporation to the effect that such registration
                           is not required.

                           investment purposes only, and not with a view toward

                           4.4.4 Corporation Information. The Purchaser: (1) has
                           received and read all information that it has
                           requested regarding the Corporation's business,
                           management and financial affairs; and (2) had the
                           opportunity to ask questions of and receive answers
                           from the Corporation and its management regarding the
                           terms and conditions of Purchaser's investment in the
                           Corporation.

                           would likely cause any representation or warranty
                           contained herein to be untrue or inaccurate in any
                           material respect, or any covenant, condition, or
                           agreement contained herein not to be complied with or
                           satisfied in any material respect.

                           Purchaser, the Corporation shall execute, acknowledge
                           and deliver all such further assignments, transfers,
                           conveyances, powers of attorney and assurances as may
                           be required or appropriate to convey and transfer to
                           and vest in such Purchaser and protect its right,
                           title and interest in all of the Shares, Warrants and
                           Warrant Shares and to carry out the transactions
                           contemplated by this Agreement.

         8. Remedies. On the occurrence of a default that remains uncured upon
the expiration of ten (10) days following delivery of written notice to the

non-defaulting party may elect to exercise any remedy at law or in equity or any
remedy provided by this Agreement. The parties acknowledge and agree that the
Corporation will look solely to the applicable Purchaser for any breach or
default by such Purchaser, and no Purchaser shall be liable for the breach or
default of any other Purchaser under this Agreement, the Note, the Pledge and
Security Agreement, the Registration Rights Agreement and each of the Related

                  9.3      Consent to Amendments; Waivers. The provisions of
                           this Agreement may be amended or waived at any time

                           waiver of or otherwise prejudice any such right,
                           power or remedy.

THIS WARRANT AND ANY SHARES OF COMMON STOCK ISSUABLE UPON EXERCISE THEREOF HAVE
NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 AS AMENDED, OR UNDER ANY
STATE SECURITIES LAWS AND MAY NOT BE SOLD, PLEDGED, TRANSFERRED, ASSIGNED, OR
OTHERWISE DISPOSED OF EXCEPT IN ACCORDANCE WITH SUCH ACT AND THE RULES AND
REGULATIONS THEREUNDER AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS.
ZIXIT CORPORATION (THE "COMPANY") WILL TRANSFER SUCH WARRANT AND ANY SHARES OF
COMMON STOCK ISSUABLE UPON EXERCISE THEREOF ONLY UPON RECEIPT OF AN OPINION OF
COUNSEL, IN FORM AND SUBSTANCE SATISFACTORY TO THE COMPANY, THAT THE
REGISTRATION PROVISIONS OF SUCH ACT HAVE BEEN COMPLIED WITH OR THAT SUCH
REGISTRATION IS NOT REQUIRED AND THAT SUCH TRANSFER WILL NOT VIOLATE ANY
APPLICABLE STATE SECURITIES LAWS.



                        COMMON STOCK WARRANT CERTIFICATE

                                ZIXIT CORPORATION

April __, 2000

No. __                                 For the Purchase of ___________ Shares of
                                       Common Stock of Zixit Corporation


         FOR VALUE RECEIVED, ___________________________________ (the "Holder")
or the Holder's registered assigns is hereby granted the right to purchase from
Zixit Corporation, a Texas corporation (the "Company"), ___________ shares (the
"Warrant Shares", which number shall be adjusted from time to time in accordance
with Section 2 hereof) of the Company's Common Stock, par value $.01 per share
(the "Common Stock"), at a purchase price of $57.60 per share (as adjusted from
time to time in accordance with Section 2 hereof, the "Exercise Price"),
exercisable in whole or in part at any time and from time to time from April __,
2000 until 6:00 p.m. on the date that is ten years after the date hereof (the
"Exercise Period"), on the terms and conditions set forth in this Warrant (this
"Warrant").

I.       EXERCISE

         1.1 EXERCISE OF WARRANT. This Warrant may be exercised, in whole or in
part, at any time or from time to time, during the Exercise Period by (i)
surrendering this Warrant Certificate, with the form of exercise notice attached
hereto as Exhibit A duly executed by the Holder, to the Company at its principal
office, and (ii) making payment to the Company of the aggregate Exercise Price
for the applicable Warrant Shares in cash, by certified check, bank check or
wire transfer to an account designated by the Company. The minimum number of
shares of Common Stock with respect to which this Warrant may be exercised, in
whole or in part, at any time shall be the lesser of twenty-five percent (25%)
of the total number of Warrant Shares which may be purchased under this Warrant
or the maximum number of Warrant Shares available for purchase under this
Warrant

<PAGE>   2

at the time of exercise. Upon any partial exercise of this Warrant, the Company,
at its expense, shall promptly issue to the Holder for Holder's surrendered
Warrant Certificate a replacement Warrant Certificate identical in all respects
to this Warrant Certificate, except that the number of Warrant Shares shall be
reduced accordingly.

         1.2 ISSUANCE OF WARRANT SHARES. The Warrant Shares purchased by Holder
shall be issued as of the close of business on the date on which all actions
required to be taken by the Holder and all payments required to be received by
the Company, pursuant to Section 1.1, shall have been so taken and received.
Certificates for the Warrant Shares so purchased shall be delivered to the
Holder as soon as practicable after this Warrant is surrendered and the Exercise
Price is received.

II.      ADJUSTMENTS TO WARRANT.

         The number of Warrant Shares for which this Warrant is exercisable and
the Exercise Price shall be subject to adjustment from time to time as set forth
below.

         2.1 STOCK DIVIDENDS, SUBDIVISIONS AND COMBINATIONS. If the Company
shall, at any time or from time to time: (a) make (or fix a record date for the
holders of shares of its Common Stock entitled to receive) a dividend payable
in, or other distribution of, additional shares of Common Stock, (b) subdivide
its outstanding shares of Common Stock into a larger number of shares of Common
Stock, or (c) combine its outstanding shares of Common Stock into a smaller
number of shares of Common Stock, then (i) the number of Warrant Shares issuable
upon the exercise of this Warrant immediately prior to the occurrence of any
such event shall be adjusted so that the Holder of this Warrant upon exercise on
or after that date shall be entitled to receive the aggregate number of Warrant
Shares which the Holder of this Warrant would have owned and been entitled to
receive as a result of such event had this Warrant been exercised immediately
prior thereto, and (ii) the Exercise Price in effect immediately prior to such
event shall be adjusted by multiplying such Exercise Price by a fraction, the
numerator of which is the aggregate number of Warrant Shares purchasable upon
exercise of this Warrant immediately prior to such event, and the denominator of
which is the aggregate number of Warrant Shares purchasable upon exercise of
this Warrant immediately thereafter.

         2.2 DIVIDENDS AND DISTRIBUTIONS IN OTHER SECURITIES. If the Company
shall, at any time or from time to time, make (or fix a record date for the
holders of shares of its Common Stock entitled to receive) a dividend or other
distribution payable in other securities of the Company or in the securities of
any subsidiary of the Company (other than shares of Common Stock), then lawful
and adequate provision shall be made so that the Holder of this Warrant shall be
entitled to receive upon exercise of this Warrant, for the aggregate Exercise
Price in effect prior thereto, in addition to the number of Warrant Shares
immediately theretofore issuable upon exercise of this Warrant, the kind and
number of other securities of the Company or securities of any subsidiary of the
Company, which the Holder would have owned and been entitled to receive had this
Warrant been exercised immediately prior to that date.

         2.3 CASH DIVIDENDS AND DISTRIBUTIONS. If the Company shall, at any time
or from time to time, make (or fix a record date for the holders of shares of
its Common Stock entitled to receive)



                                      -2-
<PAGE>   3

a dividend payable in, or other distribution of cash, then the number of Warrant
Shares issuable upon the exercise of the Warrant, for the aggregate Exercise
Price in effect prior thereto, immediately prior to the occurrence of any such
event shall be increased by: (i) the amount of the dividend the Holder of this
Warrant would have received had the Holder exercised its warrant immediately
prior to the record date (or, if no record date has been set the date of
distribution or dividend), divided by (ii) the Current Market Price of the
Company's Common Stock. As used in this Warrant the term "Current Market Price"
means with respect to any security: (a) for so long as the issuer is a Public
Entity (as hereafter defined), and the security is traded on an organized
exchange the average closing price of the security on the stock exchange where
the security is traded or the last bid price as quoted on the NASDAQ for the
immediately preceding five (5) trading days; and (b) for so long as the issuer
is not a Public Entity or the security is not traded on an organized exchange,
the price per share of the security as determined in good faith by the
Corporation's board of directors. If such valuation is objected to by the Holder
of this Warrant, such valuation will be made by a reputable investment bank of
national standing mutually selected by the Holder and the Corporation, the
expense of which will be paid by the Corporation. "Public Entity" will mean: (i)
an entity that has registered its Common Stock pursuant to Section 12(b) or
Section 12(g) of the Securities Exchange Act of 1934, as amended, and (ii) the
aggregate market value of Common Stock held by nonaffiliates which is then
available for public trading is not less than Twenty-Five Million Dollars
($25,000,000.00), computed by reference to the closing price of the Common Stock
on the stock exchange where the Common Stock is traded or the last bid price as
quoted on the NASDAQ.

         2.4 REORGANIZATIONS, MERGERS, CONSOLIDATIONS OR SALES OF ASSETS. If any
of the following transactions (each, a "Special Transaction") shall become
effective: (a) a capital reorganization, whether by reclassification, exchange,
substitution or otherwise (other than a stock or cash dividend, subdivision,
combination or other distribution provided for elsewhere in this Section 2), (b)
a consolidation or merger of the Company with another entity, or (c) a sale or
conveyance of all or substantially all of the Company's assets; then as a
condition of any such Special Transaction, lawful and adequate provision shall
be made so that the Holder of this Warrant shall thereafter have the right to
purchase and receive upon exercise of this Warrant, in lieu of the Warrant
Shares immediately theretofore issuable upon exercise of this Warrant, for the
aggregate Exercise Price in effect immediately prior to such consummation, such
shares of stock, other securities, cash or other assets as may be issued or
payable in and pursuant to the terms of such Special Transaction to the holders
of shares of Common Stock for which this Warrant could have been exercised
immediately prior to such Special Transaction. In connection with any Special
Transaction, appropriate provision shall be made with respect to the rights and
interests of the Holder of this Warrant to the end that the provisions of this
Warrant (including without limitation the provisions of this Section 2), shall
thereafter be applicable, as nearly as may be practicable, to any shares of
stock, other securities, cash or other assets thereafter deliverable upon the
exercise of this Warrant.

         2.5 NOTICE. In the event that:

                  (a) the Company shall fix a record date for the holders of
         shares of its Common Stock for the purpose of entitling them to receive
         any dividend or other distribution of shares of Common Stock or other
         securities of the Company; or



                                      -3-
<PAGE>   4

                  (b) the Company shall enter into any agreement or adopt any
         plan for a capital reorganization of the Company, the consolidation or
         merger of the Company with or into another entity, or the sale or
         conveyance of all or substantially all of the assets of the Company to
         another entity; or

                  (c) the Company shall adopt any plan for or otherwise shall
         become subject to any voluntary or involuntary dissolution, liquidation
         or winding up of the Company; or

                  (d) the Company shall propose to take any other action which
         would require an adjustment pursuant to Sections 2.1 through 2.4,

then, and in each such case, the Company shall mail or cause to be mailed to the
Holder of this Warrant a notice specifying, as the case may be: (i) the date on
which a record is to be fixed for the purpose of such dividend or distribution,
and stating the amount and character of such dividend or distribution, or (ii)
the date on which such reorganization, consolidation, merger, conveyance,
dissolution, liquidation or winding up or other action is to become effective,
and the time, if any, to be fixed, as to which the holders of record of Common
Stock shall be entitled to exchange their shares of Common Stock for securities
or other property deliverable upon such reorganization, consolidation, merger,
conveyance, dissolution, liquidation or winding up or other action. Such notice
shall be mailed at least 20 days prior to the date therein specified and this
Warrant may be exercised prior to said date during the Exercise Period.

         2.6 FRACTIONAL INTERESTS. The Company shall not be required to issue
fractions of shares of Common Stock upon the exercise of this Warrant. If any
fraction of a share of Common Stock would be issuable upon the exercise of this
Warrant, the Company shall, in lieu of such issuance, purchase such fraction for
an amount in cash equal to the current value of such fraction, computed on the
basis of the Current Market Price of the Common Stock on the last business day
prior to the date of exercise upon which such a sale of Common Stock shall have
been effected.

         2.7 EFFECT OF ALTERNATE SECURITIES. If at any time, as a result of an
adjustment made pursuant to this Section 2, the Holder of this Warrant shall
thereafter become entitled to receive any securities of the Company other than
shares of Common Stock, then the number of such other securities receivable upon
exercise of this Warrant shall be subject to adjustment from time to time on
terms as nearly equivalent as practicable to the provisions with respect to the
Warrant Shares as contained in this Section 2.

         2.8 SUCCESSIVE APPLICATION; READJUSTMENT. The provisions of this
Section 2 shall similarly apply from time to time to successive events covered
by this Section. If the Company shall fix a record date for the holders of its
Common Stock for the purpose of entitling them to receive a dividend or
distribution and shall, thereafter and before the distribution to shareholders
thereof, legally abandon its plan to pay or deliver such dividend or
distribution, then thereafter no adjustment shall be required by reason of the
taking of such record date and any such adjustment previously made in respect
thereof shall be rescinded and annulled.



                                      -4-
<PAGE>   5

           2.9 CERTIFICATE AS TO ADJUSTMENTS. In the event of an adjustment in
the number of Warrant Shares or in the Exercise Price, the Company at its
expense will promptly compute such adjustment in accordance with the terms of
this Warrant and prepare a certificate executed by an executive officer of the
Company setting forth such adjustment and showing in detail the facts upon which
such adjustment is based. The Company will forthwith mail a copy of each such
certificate to the Holder.

III.     RIGHTS OF THE HOLDER

         3.1 NO RIGHTS AS SHAREHOLDER. The Holder shall not, solely by virtue of
this Warrant and prior to the issuance of the Warrant Shares upon due exercise
hereof, be entitled to any rights of a shareholder in the Company.

         3.2 NO IMPAIRMENT; CERTAIN COVENANTS. The Company shall not by any
action including, without limitation, amending its certificate of incorporation
or through any reorganization, transfer of assets, consolidation, merger,
dissolution, issue or sale of securities or any other voluntary action, avoid or
seek to avoid the observance or performance of any of the terms of this Warrant,
but will at all times in good faith assist in the carrying out of all such terms
and in the taking of all such actions as may be necessary or appropriate to
protect the rights of the Holder against impairment. Without limiting the
generality of the foregoing, the Company will (a) take all such action as may be
necessary or appropriate in order that the Warrant Shares will, upon issuance in
accordance with the terms hereof and the payment of the Exercise Price therefor,
be duly authorized, validly issued and outstanding, fully paid and
non-assessable, and free from all taxes, liens and charges with respect to the
issuance thereof, (b) at all times during the Exercise Period have authorized
and reserved sufficient shares of Common Stock to provide for the exercise of
this Warrant in full, and (c) use its best efforts to obtain all such
authorizations, exemptions or consents from any public regulatory body having
jurisdiction thereof as may be necessary to enable the Company to perform its
obligations under this Warrant.

IV.      REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

         The Company represents and warrants to and agrees with the Holder as
follows:

         4.1 Sufficient Shares. The Company has authorized sufficient shares of
Common Stock to fulfill the Company's obligations under this Warrant and all of
the other warrants, options and convertible securities issued by the Company. On
exercise of this Warrant and satisfaction of the Exercise Price, the Warrant
Shares issued to the Holder will be validly issued, fully paid, non-assessable
and free and clear of all liens, claims and encumbrances, except as may be
imposed by the Pledge and Security Agreement dated as of the date hereof, or any
liens, claims, or encumbrances permitted by or imposed by the Holder.

         4.2 Authority. The Company has taken all necessary action to authorize
the execution and delivery of this Warrant and the issuance of the Warrant
Shares on the exercise of this Warrant. This Warrant is a valid, binding and
enforceable obligation of the Company. The execution, delivery and performance
of this Warrant will not violate: (a) any provision of the organizational
documents

V.       RESTRICTIVE LEGEND.

         5.1 This Warrant is being acquired and any Warrant Shares to be
acquired by the Holder pursuant to this Warrant (collectively, "Securities")
will be acquired for investment for the Holder's own account and not for resale
in connection with any distribution of such Securities within the meaning of the
Securities Act of 1933 (the "Securities Act"). The Securities will not be sold,
transferred or otherwise disposed of without registration under the Securities
Act and state securities laws or qualification for exemptions therefrom. The
Holder agrees that, until the Company has caused the registration of such shares
under the Securities Act of 1933, as amended, each certificate evidencing the
Warrant Shares may be inscribed with a legend to the foregoing effect, which
legend will be as follows:

                  The shares represented by this certificate have been acquired
                  solely for investment purposes and have not been registered
                  under the Securities Act of 1933, as amended, or the
                  securities laws of any state. The shares may not be sold,
                  transferred, assigned or otherwise disposed of unless and
                  until such shares are first registered under the Securities
                  Act of 1933, all applicable state securities laws and all
                  rules and regulations promulgated thereunder or unless and
                  until the holder hereof provides either (i) information
                  reasonably satisfactory to the Company that such registration
                  is not required or (ii) an opinion of counsel reasonably
                  acceptable to the Company to the effect that such registration
                  is not required.

VI.      REGISTRATION RIGHTS AGREEMENT.

         6.1 This Warrant and the Warrant Shares will qualify for all benefits
and be subject to the terms and conditions of that certain Registration Rights
Agreement of even date herewith among the Company, the Holder and others (the
"Registration Rights Agreement"). The Holder agrees that each certificate
evidencing the Warrant Shares may be inscribed with a legend to the foregoing
effect as provided in the Registration Rights Agreement.

VII.     TRANSFER OR LOSS OF WARRANT.

         7.1 TRANSFER. Subject to compliance with federal and state securities
laws, the Holder may sell, assign, transfer or otherwise dispose of all or any
portion of this Warrant or the Warrant Shares acquired upon any exercise hereof
at any time and from time to time. Upon the sale, assignment, transfer or other
disposition of all or any portion of this Warrant, the Holder shall deliver to
Company a written notice of such in the form attached hereto as Exhibit B duly

transferability specified in this Warrant are intended to provide certain
protections to the Holder and the Company and to ensure compliance with the
provisions of the Securities Act and applicable state securities laws in respect
of the transfer of any Warrant or any Warrant Shares and are to be strictly
construed.

         7.2 LOST, STOLEN, DESTROYED OR MUTILATED WARRANTS. In case any Warrant
is mutilated, lost, stolen or destroyed, the Company agrees to issue a new
Warrant of like date, tenor and denomination and deliver the same in exchange
and substitution for and upon surrender and cancellation of any mutilated
Warrant, or in lieu of any Warrant lost, stolen or destroyed, on receipt of
evidence reasonably satisfactory to the Company of the loss, theft or

THIS WARRANT AND ANY SHARES OF COMMON STOCK ISSUABLE UPON EXERCISE THEREOF HAVE

STATE SECURITIES LAWS AND MAY NOT BE SOLD, PLEDGED, TRANSFERRED, ASSIGNED, OR

                                ZIXIT CORPORATION

April __, 2000

No. __                                 For the Purchase of ___________ Shares of
                                       Common Stock of Zixit Corporation


         FOR VALUE RECEIVED, ___________________________________ (the "Holder")
or the Holder's registered assigns is hereby granted the right to purchase from
Zixit Corporation, a Texas corporation (the "Company"), ___________ shares (the
"Warrant Shares", which number shall be adjusted from time to time in accordance
with Section 2 hereof) of the Company's Common Stock, par value $.01 per share
(the "Common Stock"), at a purchase price of $12.00 per share (as adjusted from
time to time in accordance with Section 2 hereof, the "Exercise Price"),
exercisable in whole or in part at any time and from time to time from April __,
2001 until 6:00 p.m. on the date that is four (4) years after the date hereof
(the "Exercise Period"), on the terms and conditions set forth in this Warrant
(this "Warrant").

I.       EXERCISE

         1.1 EXERCISE OF WARRANT. This Warrant may be exercised, in whole or in
part, at any time or from time to time, during the Exercise Period by (i)
surrendering this Warrant Certificate, with the form of exercise notice attached
hereto as Exhibit A duly executed by the Holder, to the Company at its principal
office, and (ii) making payment to the Company of the aggregate Exercise Price
for the applicable Warrant Shares in cash, by certified check, bank check or
wire transfer to an account designated by the Company. The minimum number of
shares of Common Stock with respect to which this Warrant may be exercised, in
whole or in part, at any time shall be the lesser of twenty-five percent (25%)
of the total number of Warrant Shares which may be purchased under this Warrant
or the maximum number of Warrant Shares available for purchase under this
Warrant



<PAGE>   2

at the time of exercise. Upon any partial exercise of this Warrant, the Company,
at its expense, shall promptly issue to the Holder for Holder's surrendered
Warrant Certificate a replacement Warrant Certificate identical in all respects
to this Warrant Certificate, except that the number of Warrant Shares shall be
reduced accordingly.

         1.2 ISSUANCE OF WARRANT SHARES. The Warrant Shares purchased by Holder
shall be issued as of the close of business on the date on which all actions
required to be taken by the Holder and all payments required to be received by
the Company, pursuant to Section 1.1, shall have been so taken and received.
Certificates for the Warrant Shares so purchased shall be delivered to the
Holder as soon as practicable after this Warrant is surrendered and the Exercise
Price is received.

II.      ADJUSTMENTS TO WARRANT.

         The number of Warrant Shares for which this Warrant is exercisable and
the Exercise Price shall be subject to adjustment from time to time as set forth
below.

         2.1 STOCK DIVIDENDS, SUBDIVISIONS AND COMBINATIONS. If the Company
shall, at any time or from time to time: (a) make (or fix a record date for the
holders of shares of its Common Stock entitled to receive) a dividend payable
in, or other distribution of, additional shares of Common Stock, (b) subdivide
its outstanding shares of Common Stock into a larger number of shares of Common
Stock, or (c) combine its outstanding shares of Common Stock into a smaller
number of shares of Common Stock, then (i) the number of Warrant Shares issuable
upon the exercise of this Warrant immediately prior to the occurrence of any
such event shall be adjusted so that the Holder of this Warrant upon exercise on
or after that date shall be entitled to receive the aggregate number of Warrant
Shares which the Holder of this Warrant would have owned and been entitled to
receive as a result of such event had this Warrant been exercised immediately
prior thereto, and (ii) the Exercise Price in effect immediately prior to such
event shall be adjusted by multiplying such Exercise Price by a fraction, the
numerator of which is the aggregate number of Warrant Shares purchasable upon
exercise of this Warrant immediately prior to such event, and the denominator of
which is the aggregate number of Warrant Shares purchasable upon exercise of
this Warrant immediately thereafter.

         2.2 DIVIDENDS AND DISTRIBUTIONS IN OTHER SECURITIES. If the Company
shall, at any time or from time to time, make (or fix a record date for the
holders of shares of its Common Stock entitled to receive) a dividend or other
distribution payable in other securities of the Company or in the securities of
any subsidiary of the Company (other than shares of Common Stock), then lawful
and adequate provision shall be made so that the Holder of this Warrant shall be
entitled to receive upon exercise of this Warrant, for the aggregate Exercise
Price in effect prior thereto, in addition to the number of Warrant Shares
immediately theretofore issuable upon exercise of this Warrant, the kind and
number of other securities of the Company or securities of any subsidiary of the
Company, which the Holder would have owned and been entitled to receive had this
Warrant been exercised immediately prior to that date.

         2.3 CASH DIVIDENDS AND DISTRIBUTIONS. If the Company shall, at any time
or from time to time, make (or fix a record date for the holders of shares of
its Common Stock entitled to receive)



                                      -2-
<PAGE>   3

a dividend payable in, or other distribution of cash, then the number of Warrant
Shares issuable upon the exercise of the Warrant, for the aggregate Exercise
Price in effect prior thereto, immediately prior to the occurrence of any such
event shall be increased by: (i) the amount of the dividend the Holder of this
Warrant would have received had the Holder exercised its warrant immediately
prior to the record date (or, if no record date has been set the date of
distribution or dividend), divided by (ii) the Current Market Price of the
Company's Common Stock. As used in this Warrant the term "Current Market Price"
means with respect to any security: (a) for so long as the issuer is a Public
Entity (as hereafter defined), and the security is traded on an organized
exchange the average closing price of the security on the stock exchange where
the security is traded or the last bid price as quoted on the NASDAQ for the
immediately preceding five (5) trading days; and (b) for so long as the issuer
is not a Public Entity or the security is not traded on an organized exchange,
the price per share of the security as determined in good faith by the
Corporation's board of directors. If such valuation is objected to by the Holder
of this Warrant, such valuation will be made by a reputable investment bank of
national standing mutually selected by the Holder and the Corporation, the
expense of which will be paid by the Corporation. "Public Entity" will mean: (i)
an entity that has registered its Common Stock pursuant to Section 12(b) or
Section 12(g) of the Securities Exchange Act of 1934, as amended, and (ii) the
aggregate market value of Common Stock held by nonaffiliates which is then
available for public trading is not less than Twenty-Five Million Dollars
($25,000,000.00), computed by reference to the closing price of the Common Stock
on the stock exchange where the Common Stock is traded or the last bid price as
quoted on the NASDAQ.

         2.4 REORGANIZATIONS, MERGERS, CONSOLIDATIONS OR SALES OF ASSETS. If any
of the following transactions (each, a "Special Transaction") shall become
effective: (a) a capital reorganization, whether by reclassification, exchange,
substitution or otherwise (other than a stock or cash dividend, subdivision,
combination or other distribution provided for elsewhere in this Section 2), (b)
a consolidation or merger of the Company with another entity, or (c) a sale or
conveyance of all or substantially all of the Company's assets; then as a
condition of any such Special Transaction, lawful and adequate provision shall
be made so that the Holder of this Warrant shall thereafter have the right to
purchase and receive upon exercise of this Warrant, in lieu of the Warrant
Shares immediately theretofore issuable upon exercise of this Warrant, for the
aggregate Exercise Price in effect immediately prior to such consummation, such
shares of stock, other securities, cash or other assets as may be issued or
payable in and pursuant to the terms of such Special Transaction to the holders
of shares of Common Stock for which this Warrant could have been exercised
immediately prior to such Special Transaction. In connection with any Special
Transaction, appropriate provision shall be made with respect to the rights and
interests of the Holder of this Warrant to the end that the provisions of this
Warrant (including without limitation the provisions of this Section 2), shall
thereafter be applicable, as nearly as may be practicable, to any shares of
stock, other securities, cash or other assets thereafter deliverable upon the
exercise of this Warrant.

         2.5 NOTICE. In the event that:

                  (a) the Company shall fix a record date for the holders of
         shares of its Common Stock for the purpose of entitling them to receive
         any dividend or other distribution of shares of Common Stock or other
         securities of the Company; or



                                      -3-
<PAGE>   4

                  (b) the Company shall enter into any agreement or adopt any
         plan for a capital reorganization of the Company, the consolidation or
         merger of the Company with or into another entity, or the sale or
         conveyance of all or substantially all of the assets of the Company to
         another entity; or

                  (c) the Company shall adopt any plan for or otherwise shall
         become subject to any voluntary or involuntary dissolution, liquidation
         or winding up of the Company; or

                  (d) the Company shall propose to take any other action which
         would require an adjustment pursuant to Sections 2.1 through 2.4,

then, and in each such case, the Company shall mail or cause to be mailed to the
Holder of this Warrant a notice specifying, as the case may be: (i) the date on
which a record is to be fixed for the purpose of such dividend or distribution,
and stating the amount and character of such dividend or distribution, or (ii)
the date on which such reorganization, consolidation, merger, conveyance,
dissolution, liquidation or winding up or other action is to become effective,
and the time, if any, to be fixed, as to which the holders of record of Common
Stock shall be entitled to exchange their shares of Common Stock for securities
or other property deliverable upon such reorganization, consolidation, merger,
conveyance, dissolution, liquidation or winding up or other action. Such notice
shall be mailed at least 20 days prior to the date therein specified and this
Warrant may be exercised prior to said date during the Exercise Period.

         2.6 FRACTIONAL INTERESTS. The Company shall not be required to issue
fractions of shares of Common Stock upon the exercise of this Warrant. If any
fraction of a share of Common Stock would be issuable upon the exercise of this
Warrant, the Company shall, in lieu of such issuance, purchase such fraction for
an amount in cash equal to the current value of such fraction, computed on the
basis of the Current Market Price of the Common Stock on the last business day
prior to the date of exercise upon which such a sale of Common Stock shall have
been effected.

         2.7 EFFECT OF ALTERNATE SECURITIES. If at any time, as a result of an
adjustment made pursuant to this Section 2, the Holder of this Warrant shall
thereafter become entitled to receive any securities of the Company other than
shares of Common Stock, then the number of such other securities receivable upon
exercise of this Warrant shall be subject to adjustment from time to time on
terms as nearly equivalent as practicable to the provisions with respect to the
Warrant Shares as contained in this Section 2.

         2.8 SUCCESSIVE APPLICATION; READJUSTMENT. The provisions of this
Section 2 shall similarly apply from time to time to successive events covered
by this Section. If the Company shall fix a record date for the holders of its
Common Stock for the purpose of entitling them to receive a dividend or
distribution and shall, thereafter and before the distribution to shareholders
thereof, legally abandon its plan to pay or deliver such dividend or
distribution, then thereafter no adjustment shall be required by reason of the
taking of such record date and any such adjustment previously made in respect
thereof shall be rescinded and annulled.

         2.9 CERTIFICATE AS TO ADJUSTMENTS. In the event of an adjustment in the
number of Warrant Shares or in the Exercise Price, the Company at its expense
will promptly compute such adjustment in accordance with the terms of this
Warrant and prepare a certificate executed by an executive officer of the
Company setting forth such adjustment and showing in detail the facts upon which
such adjustment is based. The Company will forthwith mail a copy of each such
certificate to the Holder.

III.     RIGHTS OF THE HOLDER

but will at all times in good faith assist in the carrying out of all such terms
and in the taking of all such actions as may be necessary or appropriate to
protect the rights of the Holder against impairment. Without limiting the
generality of the foregoing, the Company will (a) take all such action as may be
necessary or appropriate in order that the Warrant Shares will, upon issuance in

obligations under this Warrant.

IV.      REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

         The Company represents and warrants to and agrees with the Holder as
follows:

         4.1 Sufficient Shares. The Company has authorized sufficient shares of
Common Stock to fulfill the Company's obligations under this Warrant and all of
the other warrants, options and convertible securities issued by the Company. On
exercise of this Warrant and satisfaction of the Exercise Price, the Warrant
Shares issued to the Holder will be validly issued, fully paid, non-assessable

<PAGE>   6

or charter of the Company; (b) any order, writ, injunction or decree of any
court, administrative agency or governmental body applicable to the Company or
the Common Stock; or (c) any contract, lease, note, bond, mortgage or other
agreement to which the Company is a party, by which the Company is bound or to

V.       RESTRICTIVE LEGEND.

in connection with any distribution of such Securities within the meaning of the
Securities Act of 1933 (the "Securities Act"). The Securities will not be sold,
transferred or otherwise disposed of without registration under the Securities
Act and state securities laws or qualification for exemptions therefrom. The
Holder agrees that, until the Company has caused the registration of such shares
under the Securities Act of 1933, as amended, each certificate evidencing the
Warrant Shares may be inscribed with a legend to the foregoing effect, which
legend will be as follows:

                  The shares represented by this certificate have been acquired
                  solely for investment purposes and have not been registered
                  under the Securities Act of 1933, as amended, or the
                  securities laws of any state. The shares may not be sold,
                  transferred, assigned or otherwise disposed of unless and
                  until such shares are first registered under the Securities
                  Act of 1933, all applicable state securities laws and all
                  rules and regulations promulgated thereunder or unless and
                  until the holder hereof provides either (i) information
                  reasonably satisfactory to the Company that such registration
                  is not required or (ii) an opinion of counsel reasonably
                  acceptable to the Company to the effect that such registration
                  is not required.

VI.      REGISTRATION RIGHTS AGREEMENT.

         6.1 This Warrant and the Warrant Shares will qualify for all benefits
and be subject to the terms and conditions of that certain Registration Rights
Agreement of even date herewith among the Company, the Holder and others (the
"Registration Rights Agreement"). The Holder agrees that each certificate
evidencing the Warrant Shares may be inscribed with a legend to the foregoing
effect as provided in the Registration Rights Agreement.

VII.     TRANSFER OR LOSS OF WARRANT.

         7.1 TRANSFER. Subject to compliance with federal and state securities
laws, the Holder may sell, assign, transfer or otherwise dispose of all or any
portion of this Warrant or the Warrant Shares acquired upon any exercise hereof
at any time and from time to time. Upon the sale, assignment, transfer or other
disposition of all or any portion of this Warrant, the Holder shall deliver to
Company a written notice of such in the form attached hereto as Exhibit B duly
executed by

assignee or assignees and in the denominations specified in such instrument of
assignment, and this Warrant will promptly be canceled. The conditions to
transferability specified in this Warrant are intended to provide certain
protections to the Holder and the Company and to ensure compliance with the
provisions of the Securities Act and applicable state securities laws in respect
of the transfer of any Warrant or any Warrant Shares and are to be strictly
construed.

         7.2 LOST, STOLEN, DESTROYED OR MUTILATED WARRANTS. In case any Warrant
is mutilated, lost, stolen or destroyed, the Company agrees to issue a new
Warrant of like date, tenor and denomination and deliver the same in exchange
and substitution for and upon surrender and cancellation of any mutilated
Warrant, or in lieu of any Warrant lost, stolen or destroyed, on receipt of
evidence reasonably satisfactory to the Company of the loss, theft or

PLEDGE AGREEMENT: Stock Pledge and                    SECURITY:
Security Agreement of even date herewith              The property described in
from Maker to Holder.                                 and conveyed or encumbered
                                                      by the Pledge Agreement.


         FOR VALUE RECEIVED, Maker, jointly and severally if more than one,
hereby promises to pay to Holder, in lawful money of the United States of
America at the address of the office of the Holder set forth above, or at such
other place as Holder may designate in writing, the Principal Amount, without
interest thereon, as follows:

         Maker shall pay to Holder three equal installments of principal, each
         in an amount equal to one-third of the Principal Amount set forth
         above, on May 1, 2000, on June 30, 2000 and on September 1, 2000.

The outstanding principal balance of this Note shall not accrue interest unless
and until there is a default under this Note, at which time this Note shall bear
interest at a rate equal to the lesser of twelve percent (12%) per annum or the
highest lawful rate permitted under applicable law until

repaid in full. This Note may be prepaid in whole or in part prior to the
Maturity Date, without premium or penalty.

         The payment of this Note is secured by the Pledge Agreement, which is
by this reference incorporated herein.

         If Maker shall fail to pay the full amount of any installment of
principal due under this Note within two (2) business days of the date it is
due, or if Maker breaches any of the terms of the Pledge Agreement, and such
breach is not cured in accordance with and within the grace period provided by
the terms of the Pledge Agreement, or if Maker is adjudicated insolvent or
bankrupt or is dissolved or liquidated, then the entire outstanding principal
amount hereunder shall become due and payable at the option of the Holder upon
written notice to Maker (or, in the event Holder is adjudicated insolvent or
bankrupt, without further act or notice). Maker agrees to pay Holder reasonable
attorneys' fees and paralegal fees for the services and expenses of counsel
employed after acceleration or maturity to collect this Note, or to protect or
enforce Holder's rights in the Security (including such fees and expenses
incurred in any bankruptcy proceedings or appeals relating to such enforcement
proceedings).

         The remedies of Holder as provided herein and in the Pledge Agreement
shall be cumulative and concurrent, and may be pursued singly, successively or
together, at the sole discretion of Holder, and may be exercised as often as
occasion therefor shall arise. No act of omission or commission of Holder,
including specifically any failure to exercise any right, remedy or recourse,
shall be effective unless it is set forth in a written document executed by
Holder and then only to the extent specifically recited therein. A waiver or
release with reference to one event shall not be construed as continuing, as a
bar to, or as a waiver or release of, any subsequent right, remedy or recourse
as to any subsequent event.

         Maker hereby: (a) waives demand, presentment for payment, notice of
nonpayment, protest, notice of protest and all other notice, filing of suit and
diligence in collecting this Note, in enforcing any of the security rights under
the Pledge Agreement or in proceedings against the Security; (b) agrees to any
substitution, exchange, addition or release of any of the Security or the
addition or release of any party or person primarily or secondarily liable
hereon; (c) agrees that Holder shall not be required first to institute any
suit, or to exhaust its remedies against Maker or any other person or party to
become liable hereunder or against the Security in order to enforce payment of
this Note; (d) consents to any extension, rearrangement, renewal or postponement
of time of payment of this Note and to any other indulgency with respect hereto
without notice, consent or consideration to any of the foregoing; and (e) agrees
that, notwithstanding the occurrence of any of the foregoing (except the express
written release by Holder of Maker), Maker shall be and remain directly and
primarily, and jointly and severally if more than one, liable for all sums due
under this Note.

         All notices hereunder shall be made in accordance with the terms of the
Pledge Agreement. Whenever used in this Note, the singular number shall include
the plural, the plural the singular, and the masculine shall include the
feminine and the neuter, and the words "Maker" and "Holder" shall



                                      -2-

                       STOCK PLEDGE AND SECURITY AGREEMENT


                  THIS STOCK PLEDGE AND SECURITY AGREEMENT ("Agreement") is
entered into as of April ___, 2000, by and between the undersigned pledgor (the
"Pledgor"), and ZIXIT CORPORATION, a Texas corporation (the "Pledgee").

                  WHEREAS, pursuant to the terms of that certain Common Stock
and Warrant Purchase Agreement (the "Purchase Agreement") of even date herewith
among the Pledgee, the Pledgor and others, the Pledgor has executed and
delivered to the Pledgee a Non-Negotiable Secured Promissory Note of even date
herewith (the "Note") in the principal amount of ______________________ Dollars
($__________) in order to evidence the Pledgor's promise to pay such amount to
the Pledgee in consideration of the sale and delivery by the Pledgee to the
Pledgor of the number of shares of common stock of Zixit Corporation, par value
$.01 per share ("Common Stock") and Warrants more particularly described on
Exhibit "A" attached hereto (collectively, the "Pledged Securities"); and

                  WHEREAS, pursuant to the terms of the Purchase Agreement, the
Pledgor has agreed to make the pledge contemplated by this Agreement.

                  NOW, THEREFORE, in consideration of the premises and the
mutual covenants contained herein, the Pledgor hereby agrees with the Pledgee as
follows:

         1. PLEDGE.

                  A. Pledged Collateral. Subject to the provisions of Section
1.B below, the Pledgor hereby pledges to the Pledgee, and grants to the Pledgee
a security interest in, the following (the "Pledged Collateral"): (i) all of the
Pledged Securities; (ii) any certificates issued by the Pledgee that represent
the Pledged Securities; and (iii) all dividends, cash, instruments and other
property or proceeds, from time to time received, receivable or otherwise
distributed in respect of, in exchange for, or upon exercise of, any or all of
the Pledged Securities.

                  B. Released Collateral. Notwithstanding anything to the
contrary contained in this Agreement: (i) upon payment in full of the first
installment of principal due under the Note, one- third of the number of shares
of Common Stock and Warrants pledged hereunder ("Released Pledged Securities"),
together with any of the items referenced in Subsections 1A(ii) and (iii) hereof
with respect to such Released Pledged Securities (collectively, the "Released
Collateral"), automatically shall be deemed released from the security interest
granted hereunder and shall no longer be deemed Pledged Collateral, and
thereupon the security interest, the pledge and all other provisions of this
Agreement with respect to such Released Collateral shall automatically cease and
terminate and be of no further force or effect and Pledgee shall immediately
cause the Released Collateral to be delivered to Pledgor; (ii) provided that no
payment Event of Default (defined below) shall have occurred and be continuing,
upon payment in full of the second installment of principal due under the Note,

items referenced in Subsections 1A(ii) and (iii) hereof with respect to such
Additional Released Pledged Securities (collectively, the "Additional Released
Collateral"), automatically shall be deemed released from the security interest
granted hereunder and shall no longer be deemed Pledged Collateral, and
thereupon the security interest, the pledge and all other provisions of this
Agreement with respect to such Additional Released Collateral shall
automatically cease and terminate and be of no further force or effect and
Pledgee shall immediately cause the Additional Released Collateral to be
delivered to Pledgor; and (iii) provided that no payment Event of Default shall
have occurred and is continuing, upon payment in full of the third installment
of principal due under the Note, all of the remaining Pledged Collateral
hereunder automatically shall be deemed released from the security interest
granted hereunder, shall be deemed Additional Released Collateral and shall no
longer be deemed Pledged Collateral, and thereupon the security interest, the
pledge and all other provisions of this Agreement with respect to such
Additional Released Collateral shall automatically cease and terminate and be of
no further force or effect, and Pledgee shall immediately cause such Additional
Released Collateral to be delivered to Pledgor. Notwithstanding the foregoing,

have occurred and is continuing, the entire Pledged Collateral automatically
shall be deemed released from the security interest granted hereunder, shall be
deemed Released Collateral and Additional Released Collateral and shall no
longer be deemed Pledged Collateral, and thereupon the security interest, the
pledge and all other provisions of this Agreement with respect to such
collateral shall automatically cease and terminate and be of no further force or
effect and Pledgee shall immediately cause such collateral to be delivered to
Pledgor.

         2. SECURITY FOR OBLIGATIONS. This Agreement secures, and the Pledged

         is entitled to exercise pursuant to paragraph (i) above and to receive
         the dividends and other distributions which it is authorized to receive
         and retain pursuant to paragraph (ii) above.

                           (i) Upon written notice by the Pledgee to the
         Pledgor, all rights of the Pledgor to exercise the voting and other
         consensual rights which it would otherwise be entitled to exercise
         pursuant to Section 5A(i) above shall cease, and all such rights shall
         thereupon become vested in the Pledgee who shall thereupon have the
         sole right to exercise such voting and other consensual rights;

                           (ii) All rights of the Pledgor to receive the
         dividends which it would otherwise be authorized to receive and retain
         pursuant to Section 5A(ii) above shall cease, and all such rights shall

         sole right to receive and hold as Pledged Collateral such dividends;
         and

                           (iii) All dividends which are received by the Pledgor
         contrary to the provisions of paragraph (ii) of this Section 5(B) shall
         be received in trust for the benefit of the Pledgee and shall be paid
         over to the Pledgee.

         6. TRANSFERS AND OTHER LIENS. The Pledgor agrees that it will not (i)
sell or otherwise dispose of, or grant any option or warrant with respect to,
any of the Pledged Collateral, or (ii) create or permit to exist any lien upon

         7. ATTORNEY-IN-FACT. Upon the occurrence and during the continuance of
an Event of Default, the Pledgor hereby irrevocably appoints the Pledgee as the
Pledgor's attorney-in-fact and proxy, with full authority in the place of the
Pledgor and in the name of the Pledgor, from time to time in the Pledgee's
reasonable discretion and upon three (3) days' written notice to the Pledgor, to
take any action and to execute any instrument which the Pledgee reasonably may
deem necessary to accomplish the purposes of this Agreement, including, without
limitation, to receive, indorse and collect all instruments made payable to the
Pledgor representing any dividend or other distribution in respect of any
Pledged Collateral and to give full discharge for the same. The powers of
attorney granted pursuant to this Agreement shall not impose any duty upon the
attorney-in-fact to exercise such powers. Such powers of attorney are coupled
with an interest and are irrevocable.

         8. REASONABLE CARE. The Pledgee shall exercise reasonable care in the
custody and preservation of the Pledged Collateral in its possession and, at a
minimum, shall ensure that the Pledged Collateral is accorded treatment
substantially equal to that which the Pledgee accords its own property.

         9. REMEDIES UPON AN EVENT OF DEFAULT. Upon and after the occurrence of
an Event of Default, the Pledgee shall have the rights and remedies provided in

Agreement. In addition to and in conjunction with such rights and remedies, the
Pledgee may, by giving ten days' written notice to Pledgor by registered mail,
sell all the Pledged Collateral in accordance with the requirements of the Texas
Uniform Commercial Code. At any bona fide public sale, Pledgee may purchase all
or any part of the Pledged Collateral. Pledgee may retain out of the proceeds of
any sale an amount equal to the amounts outstanding under the Note, including
the reasonable expenses of the sale, and shall pay any balance of the proceeds
to Pledgor. If the sale proceeds are insufficient to cover the Secured
Obligation, Pledgor shall remain liable to Pledgee for the deficiency.

         10. AMENDMENTS. No amendment or waiver of any provision of this
Agreement shall be effective unless the same shall be in writing and signed by
the Pledgor and the Pledgee, and then such waiver or consent shall be effective
only in the specific instance and for the specific purpose for which given.

provided for hereunder shall be in writing and mailed by certified mail, return
receipt requested, confirmed telecopy, or delivered by courier, if to the
Pledgor or the Pledgee, addressed to the Pledgor or the Pledgee, as the case may
be, at its address specified in the Note, or, as to each party, at such other
address as shall be designated by such party in a written notice to each other
party complying as to delivery with the terms of this Section. All such notices
and other communications shall be deemed delivered within three (3) business
days after the date mailed or upon delivery if sent by courier.

         12. CONTINUING SECURITY INTEREST. This Agreement shall create a
continuing security interest in the Pledged Collateral and shall: (i) subject to
the provisions of Section 1.B above, remain in full force and effect until
indefeasible payment in full of the Secured Obligation; (ii) be binding

governed by, and construed and interpreted in accordance with, the laws of the
State of Texas, without regard to its conflict of laws principles. Wherever

caused this Agreement to be duly executed and delivered by its duly authorized

development or transaction then pending or in progress that involves the
Company; and (b) the Company notifies the Requesting Holders in writing, within
five (5) days after the Necessary Holders have requested such registration, of
such postponement and the grounds therefor; provided that the Company shall not
postpone effecting such registration pursuant to this sentence more than once in
any twelve (12) month period; and, provided, further, that the Company shall
promptly proceed with its obligations hereunder to effect such registration once
such information is publicly disclosed or the disclosure of such information is
not likely to have a material adverse effect upon such corporate development or
transaction. The Company and other securityholders who hold piggyback
registration rights shall have the right to include any of the Company's
Securities (other than Registrable Securities) in a registration statement to be
filed as part of a Requested Registration subject in all events to subsection
(e) below.

                  (b) Maximum Number of Requested Registrations Per Holder.
Notwithstanding anything herein to the contrary, the Company will not be
required to honor a Holder's request for a Requested Registration if the Company
has previously effected two (2) Effective Registrations under this Section 2.1.



                                      -4-

                  (c) Registration Statement Form. The Requested Registration
shall be on such appropriate registration form promulgated by the Commission as
shall be selected by the Company that shall permit the disposition of such
Registrable Securities in accordance with the intended method or methods
specified in the Requesting Holder's request for such registration.

                  (d) Registration Expenses. The Company will pay all
Registration Expenses incurred in connection with any Requested Registration.

                  (e) Priority in Cutback Registrations. If a Requested
Registration becomes a Cutback Registration, the Company will include in any
such registration to the extent of the number which the Managing Underwriter
advises the Company can be sold in such offering (i) first, Registrable
Securities requested to be included by the Requesting Holder, and (ii) second,
other securities of the Company, if permitted, proposed to be included in such
registration, allocated among the Company and the holders thereof in accordance
with the priorities then existing among the Company and the holders of such
other securities; and any securities so excluded shall be withdrawn from and
shall not be included in such Requested Registration.

         2.2 Piggyback Registrations.

                  (a) Right to Include Registrable Securities. Unless the
Company has registered for resale the Registrable Securities pursuant to Section
1 or Section 2.1, then if the Company at any time proposes to effect a Piggyback
Registration after June 1, 2000, it will each such time give prompt written
notice (a "Notice of Piggyback Registration"), at least twenty (20) days prior
to the anticipated filing date, to all Holders of Registrable Securities of its
intention to do so and of such Holders' rights under this Section 2.2, which
Notice of Piggyback Registration shall include a description of the intended
method of disposition of such securities. Upon the written request of any Holder
made within fifteen (15) days after receipt of a Notice of Piggyback
Registration (which request shall specify the Registrable Securities intended to
be disposed of by such Holder and, subject to the provisions of Section 2.3(b),
the intended method of disposition thereof), the Company will use its best
efforts to include in the registration statement relating to such Piggyback
Registration all Registrable Securities which the Company has been so requested
to register. Notwithstanding the foregoing, if, at any time after giving a
Notice of Piggyback Registration and prior to the effective date of the
registration statement filed in connection with such registration, the Company
determines for any reason not to register or to delay registration of such
securities, the Company may, at its election, give written notice of such
determination to each Holder of Registrable Securities and, thereupon, (i) in
the case of a determination not to register, the Company will be relieved of its
obligation to register any Registrable Securities in connection with such
registration (but not from its obligation to pay the Registration Expenses in
connection therewith), and (ii) in the case of a determination to delay
registering, the Company shall be permitted to delay registering any Registrable
Securities for the same period as the delay in registering such other
securities. No registration effected under this Section 2.2 shall relieve the
Company of its obligations to effect a Requested Registration under Section 2.1.



                                      -5-
<PAGE>   6

                  (b) Registration Expenses. The Company will pay all
Registration Expenses incurred in connection with each Piggyback Registration.

                  (c) Priority in Cutback Registrations. If a Piggyback
Registration becomes a Cutback Registration, the Company will include in such
registration to the extent of the amount of the securities which the Managing
Underwriter advises the Company can be sold in such offering: (1) first, if such
registration as initially proposed by the Company was primarily a registration
of its securities for its own account, the securities proposed by the Company to
be sold for its own account; (2) second, if such registration was primarily a
registration of securities pursuant to the demand registration rights of a third
party, the securities proposed to be sold for such party's account; and (3)
third, any Registrable Securities and other securities requested to be included
in such registration by Requesting Holders or other Persons holding registration
rights, pro rata on the basis of the number of securities sought to be sold by
Requesting Holders or other Persons holding registration rights.

         2.3 Registration Procedures. If and whenever the Company is required to
use its best efforts to effect the registration of any Registrable Securities
under the Securities Act pursuant to Section 2.1 or Section 2.2, the Company
shall use its best efforts to effect the registration of such Registrable
Securities in accordance with the intended methods of disposition thereof
specified by the Requesting Holder(s). Without limiting the foregoing, the
Company in each such case will use its best efforts to, as expeditiously as
possible:

                  (a) prepare and file with the Commission the requisite
registration statement to effect such registration and use its best efforts to
cause such registration statement to become effective, provided that such
registration statement or any amendment thereto will not be filed with the
Commission until the Requesting Holder(s) and their counsel have had a
reasonable opportunity to review the same and to exercise their rights under
Section 2.3(j);

                  (b) prepare and file with the Commission such amendments and
supplements to such registration statement and any prospectus used in connection
therewith as may be reasonably necessary to maintain the effectiveness of such
registration statement and to comply with the provisions of the Securities Act
with respect to the disposition of all Registrable Securities covered by such
registration statement, in accordance with the intended methods of disposition
thereof, until the earlier of (i) such time as all of such securities have been
disposed of in accordance with the intended methods of disposition by the seller
or sellers thereof set forth in such registration statement and (ii) for as long
as the Warrants remain exercisable;

                  (c) promptly notify each Requesting Holder and the underwriter
or underwriters, if any:

                           (1) when such registration statement or any
prospectus used in connection therewith, or any amendment or supplement thereto,
has been filed and, with respect to such registration statement or any
post-effective amendment thereto, when the same has become effective;



                                      -6-
<PAGE>   7

                           (2) of any written comments from the Commission with
respect to any filing referred to in clause (1) above and of any written request
by the Commission for amendments or supplements to such registration statement
or prospectus;

                           (3) of the notification to the Company by the
Commission of its initiation of any proceeding with respect to the issuance by
the Commission of, or of the issuance by the Commission of, any stop order
suspending the effectiveness of such registration statement; and

                           (4) of the receipt by the Company of any notification
with respect to the suspension of the qualification or registration of any
Registrable Securities for sale under the applicable securities or blue sky laws
of any jurisdiction;

                  (d) furnish to each seller of Registrable Securities covered
by such registration statement such number of conformed copies of such
registration statement and of each amendment and supplement thereto (in each
case including all exhibits and documents incorporated by reference), such
number of copies of the prospectus contained in such registration statement
(including each preliminary prospectus and any summary prospectus) and any other
prospectus filed under Rule 424 (or any successor rule) promulgated under the
Securities Act relating to such Holder's Registrable Securities, and such other
documents, as such seller may reasonably request to facilitate the disposition
of its Registrable Securities;

                  (e) unless otherwise exempt from such requirements in such
applicable jurisdictions, use its best efforts to register or qualify all
Registrable Securities covered by such registration statement under such other
securities or blue sky laws of such jurisdictions as each Holder thereof shall
reasonably request, to keep such registration or qualification in effect for so
long as such registration statement remains in effect, and take any other action
which may be reasonably necessary or advisable to enable such Holder to
consummate the disposition in such jurisdictions of the Registrable Securities
owned by such Holder, except that the Company will not for any such purpose be
required to (i) qualify generally to do business as a foreign corporation in any
jurisdiction wherein it would not but for the requirements of this Section
2.3(e) be obligated to be so qualified, (ii) subject itself to taxation in any
such jurisdiction or (iii) consent to general service of process in any
jurisdiction;

                  (f) use its best efforts to cause all Registrable Securities
covered by such registration statement to be registered with or approved by such
other Governmental Body as may be necessary to enable each Holder thereof to
consummate the disposition of such Registrable Securities;

                  (g) in an underwritten public offering, furnish to each
Requesting Holder a signed counterpart, addressed to such Holder (and the
underwriters, if any), of



                                      -7-
<PAGE>   8

                           (1) an opinion of counsel for the Company, dated the
effective date of such registration statement, reasonably satisfactory in form
and substance to such Holder, and

                           (2) a "comfort" letter, dated the effective date of
such registration statement, signed by the independent public accountants who
have certified the Company's financial statements included in such registration
statement, in each case covering substantially the same matters with respect to
such registration statement (and the prospectus included therein) and, in the
case of the accountants' letter, with respect to events subsequent to the date
of such financial statements, as are customarily covered in opinions of issuer's
counsel and in accountants' letters delivered to the underwriters in
underwritten Public Offerings of securities, and in the case of the accountants'
letter, such other financial matters as such Holder (or underwriters, if any)
may reasonably request;

                  (h) notify each Holder of Registrable Securities covered by
such registration statement, at any time when a prospectus relating thereto is
required to be delivered under the Securities Act, of the happening of any event
as a result of which any prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state any material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, and at the request of any Holder promptly prepare and
furnish to such Holder a reasonable number of copies of a supplement to or an
amendment of such prospectus as may be necessary so that, as thereafter
delivered to the purchasers of such securities, such prospectus will not include
an untrue statement of a material fact or omit to state a material fact required
to be stated therein or necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading;

                  (i) otherwise use the Company's best efforts to comply with
all applicable rules and regulations of the Commission;

                  (j) make available for inspection by any Requesting Holder,
any underwriter participating in any disposition pursuant to such registration
statement and any attorney, accountant or other agent retained by any such
seller or underwriter (collectively, the "Inspectors"), all financial and other
records, pertinent corporate documents and properties of the Company
(collectively, the "Records") as will be reasonably necessary to enable them to
exercise their due diligence responsibility, and cause the Company's officers,
directors and employees to supply all information reasonably requested by any
such Inspector in connection with such registration statement, and permit the
Inspectors to participate in the preparation of such registration statement and
any prospectus contained therein and any amendment or supplement thereto.
Records which the Company determines, in good faith, to be confidential and
which it notifies the Inspectors are confidential will not be disclosed by the
Inspectors unless (i) the disclosure of such Records is necessary to avoid or
correct a misstatement or omission in the registration statement, (ii) the
release of such Records is ordered pursuant to a subpoena or other order from a
court of competent jurisdiction or (iii) the information in such Records has
been made generally available to the public. Each seller of Registrable
Securities agrees by acquisition of such Registrable Securities that it will,



                                      -8-
<PAGE>   9

upon learning that disclosure of such Records is sought in a court of competent
jurisdiction, give notice to the Company and allow the Company, at the Company's
expense, to undertake appropriate action to prevent disclosure of the Records
deemed confidential;

                  (k) provide a transfer agent and registrar for all Registrable
Securities covered by such registration statement not later than the effective
date of such registration statement;

                  (l) use the Company's best efforts to cause all Registrable
Securities covered by such registration statement to be listed, upon official
notice of issuance, on any securities exchange or quotation system on which any
of the securities of the same class as the Registrable Securities are then
listed;

                  (m) the Company may require each Holder of Registrable
Securities as to which any registration is being effected to, and each such
Holder, as a condition to including Registrable Securities in such registration,
will, furnish the Company with such information and affidavits regarding such
Holder and the distribution of such Securities as the Company may from time to
time reasonably request in writing in connection with such registration; and

                  (n) each Holder of Registrable Securities agrees by
acquisition of such Registrable Securities that upon receipt of any notice from
the Company of the happening of any event of the kind described in Section
2.3(h), such Holder will forthwith discontinue such Holder's disposition of
Registrable Securities pursuant to the registration statement relating to such
Registrable Securities until such Holder's receipt of the copies of the
supplemented or amended prospectus contemplated by Section 2.3(h) and, if so
directed by the Company, will deliver to the Company (at the Company's expense)
all copies, other than permanent file copies, then in such Holder's possession
of the prospectus relating to such Registrable Securities current at the time of
receipt of such notice. In the event the Company shall give any such notice,
then any periods of time in which any Holder is required to take or refrain from
taking any action referred to in this Agreement shall be deemed to be extended
by a number of days equal to the number of days during the period from and
including the giving of notice pursuant to Section 2.3(h) and to and including
the date when each holder of any Registrable Securities covered by such
registration statement will receive the copies of the supplemented or amended
prospectus contemplated by Section 2.3(h).

         2.4 Underwritten Offerings.

                  (a) Underwritten Requested Offerings. In the case of any
underwritten Public Offering being effected pursuant to a Requested
Registration, the Managing Underwriter and any other underwriter or underwriters
with respect to such offering will be selected by the Company with the prior
written approval of the Holders of a majority of the Registrable Securities to
be included in such underwritten offering which approval shall not be
unreasonably withheld. The Company will enter into an underwriting agreement in
customary form with such underwriter or underwriters, which will include, among
other provisions, indemnities to the effect and to the extent provided in
Section 2.6. The Holders of Registrable Securities to be distributed by such
underwriters will be



                                      -9-
<PAGE>   10

parties to such underwriting agreement and may, at their option, require that
any or all of the representations and warranties by, and the other agreements on
the part of, the Company to and for the benefit of such underwriters also be
made to and for their benefit and that any or all of the conditions precedent to
the obligations of such underwriters under such underwriting agreement also be
conditions precedent to their obligations. No Holder of Registrable Securities
will be required to make any representations or warranties to or agreements with
the Company or the underwriters other than representations, warranties or
agreements regarding such Holder and such Holder's ownership of the Securities
being registered on its behalf and such Holder's intended method of distribution
and any other representation required by law. No Requesting Holder may
participate in such underwritten offering unless such Holder agrees to sell its
Registrable Securities on the basis provided in such underwriting agreement and
completes and executes all questionnaires, powers of attorney, indemnities and
other documents reasonably required under the terms of such underwriting
agreement. If any Requesting Holder disapproves of the terms of an underwriting,
such Holder may elect to withdraw therefrom and from such registration by notice
to the Company and the Managing Underwriter, and each of the remaining
Requesting Holders will be entitled to increase the number of Registrable
Securities being registered to the extent of the Registrable Securities so
withdrawn in the proportion which the number of Registrable Securities being
registered by such remaining Requesting Holder bears to the total number of
Registrable Securities being registered by all such remaining Requesting
Holders.

                  (b) Underwritten Piggyback Offerings. If the Company at any
time proposes to register any of its securities in a Piggyback Registration and
such securities are to be distributed by or through one or more underwriters,
the Company will, subject to the provisions of Section 2.2(c), arrange for such
underwriters to include the Registrable Securities to be offered and sold by
such Holder among the securities to be distributed by such underwriters. All
Registrable Securities included in such a Piggyback Registration must be
distributed through such underwriters in the same manner as all other securities
are being distributed in such Public Offering. The Holders of Registrable
Securities to be distributed by such underwriters will be parties to the
underwriting agreement between the Company and such underwriter or underwriters
and may, at their option, require that any or all of the representations and
warranties by, and the other agreements on the part of, the Company to and for
the benefit of such underwriters also be made to and for their benefit and that
any or all of the conditions precedent to the obligations of such underwriters
under such underwriting agreement also be conditions precedent to their
obligations. No Holder of Registrable Securities will be required to make any
representations or warranties to or agreements with the Company or the
underwriters other than representations, warranties or agreements regarding such
Holder and such Holder's ownership of the securities being registered on its
behalf and such Holder's intended method of distribution and any other
representation required by law. No Requesting Holder may participate in such
underwritten offering unless such Holder agrees to sell its Registrable
Securities on the basis provided in such underwriting agreement and completes
and executes all questionnaires, powers of attorney, indemnities and other
documents reasonably required under the terms of such underwriting agreement. If
any Requesting Holder disapproves of the terms of an underwriting, such Holder
may elect to withdraw therefrom and from such registration by notice to the
Company and the Managing Underwriter, and each of the remaining Requesting



                                      -10-
<PAGE>   11

Holders will be entitled to increase the number of Registrable Securities being
registered to the extent of the Registrable Securities so withdrawn in the
proportion which the number of Registrable Securities being registered by such
remaining Requesting Holder bears to the total number of Registrable Securities
being registered by all such remaining Requesting Holders.

         2.5 Holdback Agreements.

                  (a) Registrable Securities. If and to the extent requested by
the Managing Underwriter, each Holder of Registrable Securities, by acquisition
of such Registrable Securities, agrees, to the extent permitted by law, not to
effect any public sale or distribution (including a sale under Rule 144) of such
Securities, or any Securities convertible into or exchangeable or exercisable
for such Securities, during the ten (10) days prior to and the ninety (90) days
after the effective date of any registration statement filed by the Company in
connection with an underwritten Public Offering (or for such shorter period of
time as is sufficient and appropriate, in the opinion of the Managing
Underwriter, in order to complete the sale and distribution of the Securities
included in such registration), except as part of such registration statement,
whether or not such Holder participates in such registration.

                  (b) By the Company. If and to the extent requested by the
Managing Underwriter, the Company agrees not to effect any public or private
sale or distribution of its equity Securities, or any Securities convertible
into or exchangeable or exercisable for such Securities, during the ten (10)
days prior to and the ninety (90) days after the effective date of the
registration statement filed in connection with an underwritten offering made
pursuant to a Requested Registration or a Piggyback Registration (or for such
shorter period of time as is sufficient and appropriate, in the opinion of the
Managing Underwriter, in order to complete the sale and distribution of the
securities included in such registration), except as part of such underwritten
registration and except pursuant to registrations on Form S-4 or Form S-8
promulgated by the Commission or any successor or similar forms thereto.

                  (c) Exception. The foregoing provisions will not apply to any
Holder of securities of the Company to the extent such Holder is prohibited by
applicable law from agreeing to withhold from sale.

         2.6 Indemnification.

                  (a) Indemnification by the Company. The Company will, to the
full extent permitted by law, indemnify and hold harmless each Holder of
Registrable Securities included in any registration statement filed in
connection with a Requested Registration or a Piggyback Registration, its
directors and officers, and each other Person, if any, who controls any such
seller within the meaning of the Securities Act, against any losses, claims,
damages, expenses or liabilities, joint or several (together, "Losses"), to
which such Holder or any such director or officer or controlling Person may
become subject under the Securities Act or otherwise, insofar as such Losses (or
actions or proceedings, whether commenced or threatened, in respect thereof)
arise out of or are based upon



                                      -11-
<PAGE>   12

any untrue or alleged untrue statement of any material fact contained in any
such registration statement, any preliminary prospectus, final prospectus or
summary prospectus contained therein, or any amendment or supplement thereto, or
any alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein (in the case of a
prospectus, in the light of the circumstances under which they were made) not
misleading, and the Company will reimburse such Holder and each such director,
officer and controlling Person for any legal or any other expenses reasonably
incurred by them in connection with investigating or defending any such Loss (or
action or proceeding in respect thereof); provided that the Company will not be
liable in any such case to the extent that any such Loss (or action or
proceeding in respect thereof) arises out of or is based upon an untrue
statement or omission made in any such registration statement, preliminary
prospectus, final prospectus, summary prospectus, amendment or supplement in
reliance upon or in conformity with written information furnished to the Company
through an instrument duly executed by or on behalf of such Holder specifically
stating that it is for use in the preparation thereof. Such indemnity will
remain in full force and effect regardless of any investigation made by or on
behalf of such Holder or any such director, officer or controlling Person, and
will survive the transfer of such Securities by such Holder. The Company will
also indemnify each other Person who participates (including as an underwriter)
in the offering or sale of Registrable Securities, their officers and directors
and each other Person, if any, who controls any such participating Person within
the meaning of the Securities Act to the same extent as provided above with
respect to sellers of Registrable Securities.

                  (b) Indemnification by the Sellers. Each Holder of Registrable
Securities which are included or are to be included in any registration
statement filed in connection with a Requested Registration or a Piggyback
Registration, as a condition to including Registrable Securities in such
registration statement, will, to the full extent permitted by law, indemnify and
hold harmless the Company, its directors and officers, and each other Person, if
any, who controls the Company within the meaning of the Securities Act, against
any Losses to which the Company or any such director or officer or controlling
Person may become subject under the Securities Act or otherwise, insofar as such
Losses (or actions or proceedings, whether commenced or threatened, in respect
thereof) arise out of or are based upon any untrue statement of any material
fact contained in any such registration statement, any preliminary prospectus,
final prospectus or summary prospectus contained therein, or any amendment or
supplement thereto, or any omission to state therein a material fact required to
be stated therein or necessary to make the statements therein (in the case of a
prospectus, in the light of the circumstances under which they were made) not
misleading, if such untrue statement or omission was made in reliance upon and
in conformity with written information furnished to the Company through an
instrument duly executed by or on behalf of such Holder specifically stating
that it is for use in the preparation of such registration statement,
preliminary prospectus, final prospectus, summary prospectus, amendment or
supplement; provided, however, that the obligation to provide indemnification
pursuant to this Section 2.6(b) will be several, and not joint and several,
among such Indemnifying Parties on the basis of the number of Registrable
Securities included in such registration statement. Such indemnity will remain
in full force and effect regardless of any investigation made by or on behalf of
the Company or any such director, officer or controlling Person and will survive
the transfer of such securities by such Holder. Such Holders will also indemnify



                                      -12-
<PAGE>   13

each other Person who participates (including as an underwriter) in the offering
or sale of Registrable Securities, their officers and directors and each other
Person, if any, who controls any such participating Person within the meaning of
the Securities Act to the same extent as provided above with respect to the
Company.

                  (c) Notice of Claims, etc. Promptly after receipt by an
Indemnified Party of notice of the commencement of any action or proceeding
involving a claim referred to in Section 2.6(a) or Section 2.6(b), such
Indemnified Party will, if a claim in respect thereof is to be made against an
Indemnifying Party pursuant to such paragraphs, give written notice to the
latter of the commencement of such action, provided that the failure of any
Indemnified Party to give notice as provided herein will not relieve the
Indemnifying Party of its obligations under the preceding paragraphs of this
Section 2.6, except to the extent that the Indemnifying Party is actually
prejudiced by such failure to give notice. In case any such action is brought
against an Indemnified Party, the Indemnifying Party will be entitled to
participate in and, unless a conflict of interest between such Indemnified Party
and any Indemnifying Party exists with respect to such claim, to assume the
defense thereof, jointly with any other Indemnifying Party similarly notified to
the extent that it may wish, with counsel reasonably satisfactory to such
Indemnified Party, and after notice from the Indemnifying Party to such
Indemnified Party of its election so to assume the defense thereof, the
Indemnifying Party will not be liable to such Indemnified Party for any legal or
other expenses subsequently incurred by the latter in connection with the
defense thereof other than reasonable costs of investigation; provided that the
Indemnified Party may participate in such defense at the Indemnified Party's
expense; and provided further that the Indemnified Party or Indemnified Parties
will have the right to employ one counsel to represent it or them if they have
legal defenses which are different from or in addition to those available to the
Indemnifying Party, and in that event the reasonable fees and expenses of such
one counsel will be paid by the Indemnifying Party. If the Indemnifying Party is
not entitled to, or elects not to, assume the defense of the claim, it will not
be obligated to pay the fees and expenses of more than one counsel for the
Indemnified Parties with respect to such claim, unless in the reasonable
judgment of any Indemnified Party a conflict of interest may exist between such
Indemnified Party and any other Indemnified Parties with respect to such claim,
in which event the Indemnifying Party will be obligated to pay the fees and
expenses of such additional counsel for the Indemnified Parties. No Indemnifying
Party will consent to entry of any judgment or enter into any settlement without
the consent of the Indemnified Party, unless only money damages are involved,
and in any event such consent will not be unreasonably withheld. No Indemnifying
Party will be subject to any liability for any settlement made without its
consent, which consent will not be unreasonably withheld.

                  (d) Contribution. If the indemnity and reimbursement
obligation provided for in any paragraph of this Section 2.6 is unavailable or
insufficient to hold harmless an Indemnified Party in respect of any Losses (or
actions or proceedings in respect thereof) referred to therein, then the
Indemnifying Party will contribute to the amount paid or payable by the
Indemnified Party as a result of such Losses (or actions or proceedings in
respect thereof) in such proportion as is appropriate to reflect the relative
fault of the Indemnifying Party on the one hand and the Indemnified Party on the
other hand in connection with statements or omissions which resulted in such
Losses, as well as any

other relevant equitable considerations. The relative fault will be determined
by reference to, among other things, whether the untrue statement of a material
fact or the omission to state a material fact relates to information supplied by
the Indemnifying Party or the Indemnified Party and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such untrue statement or omission. The parties hereto agree that it would not be
just and equitable if contributions pursuant to this Section 2.6(d) were to be
determined by pro rata allocation or by any other method of allocation which
does not take account of the equitable considerations referred to in the first
sentence of this Section 2.6(d). The amount paid by an Indemnified Party as a
result of the Losses referred to in the first sentence of this Section 2.6(d)
will be deemed to include any legal and other expenses reasonably incurred by
such Indemnified Party in connection with investigating or defending any Loss
which is the subject of this Section 2.6(d). No Indemnified Party guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) will be entitled to contribution from the Indemnifying Party if
the Indemnifying Party was not guilty of such fraudulent misrepresentation.

                  (e) Other Indemnification. Indemnification similar to that
specified in the preceding paragraphs of this Section 2.6 (with appropriate
modifications) will be given by the Company and each Holder of Registrable
Securities with respect to any required registration or other qualification of
securities under any federal or state law or regulation of any Governmental Body
other than the Securities Act. The provisions of this Section 2.6 will be in
addition to any other rights to indemnification or contribution which an
Indemnified Party may have pursuant to law, equity, contract or otherwise.

                  (f) Indemnification Payments. The indemnification required by
this Section 2.6 will be made by periodic payments of the amount thereof during
the course of the investigation or defense, as and when bills are received or
Losses are incurred.

         2.7 Covenants Relating to Rule 144. If at any time the Company is
required to file reports in compliance with either Section 13 or Section 15(d)
of the Exchange Act, the Company will file reports in compliance with the
Exchange Act, will comply with all rules and regulations of the Commission
applicable in connection with the use of Rule 144 and take such other actions
and furnish each Holder with such other information as such Holder may
reasonably request in order to avail itself of such rule or any other rule or
regulation of the Commission allowing such holder to sell any Registrable
Securities without registration, and will, at its expense, forthwith upon the
request of any holder of Registrable Securities, deliver to such holder a
certificate, signed by the Company's principal financial officer, stating (a)
the Company's name, address and telephone number (including area code), (b) the
Company's Internal Revenue Service identification number, (c) the Company's
Commission file number, (d) the number of shares of each class of stock
outstanding as shown by the most recent report or statement published by the
Company, and (e) whether the Company has filed the reports required to be filed
under the Exchange Act for a period of at least ninety (90) days prior to the
date of such certificate and in addition has filed the most recent annual report
required to be filed thereunder.

rights and benefits inuring to the Holders and the obligations imposed on the
Company hereunder shall survive any Change of Control (as herein defined). For
purposes hereof, a "Change of Control" shall mean and include any of the
following (i) a merger or consolidation of the Company with or into any other
corporation or other business entity in which the Company is the surviving
corporation (except one in which the holders of capital stock of the Company
immediately prior to such merger or consolidation continue to hold at least 50%
of the outstanding securities having the right to vote in an election of the
Board of Directors ("Voting Stock") of the Company); or any such merger or
consolidation in which the Company is not the surviving corporation; (ii) a
sale, lease, exchange or other transfer (in one transaction or a related series
of transactions) of all or substantially all of the Company's assets; (iii) the
acquisition by any person or any group of persons (other than the Company, any
of its direct or indirect subsidiaries, or any trustee, fiduciary or other
person or entity holding securities under any employee benefit plan or trust of
the Company or any of its direct or indirect subsidiaries) acting together in
any transaction or related series of transactions, of such number of shares of
the Company's Voting Stock as causes such person, or group of persons, to own
beneficially, directly or indirectly, as of the time immediately after such
transaction or series of transactions, 50% or more of the combined voting power
of the Voting Stock of the Company other than as a result of an acquisition of
securities directly from the Company, or solely as a result of an acquisition of
securities by the Company which by reducing the number of shares of the Voting
Stock outstanding increases the proportionate voting power represented by the
Voting Stock owned by any such person to 50% or more of the combined voting
power of such Voting Stock; or (iv) a change in the composition of the Company's
Board of Directors following a tender offer or proxy contest, as a result of
which persons who, immediately prior to a tender offer or proxy contest,
constituted the Company's Board of Directors shall cease to constitute at least
a majority of the members of the Board of Directors.

SECTION 4. Term. The Company's obligations under this Agreement will terminate
as to any individual Holder at the earlier of (1) the first time at which that
Holder would be entitled, under Rule 144 under the Act, to sell all of the
Common Stock and the Warrant Stock then owned by the Holder in a single three
month period regardless of the volume of trading in the Company's common stock,
and (2) the tenth anniversary of the date hereof.

        ZIXIT CORPORATION ANNOUNCES TERMS OF INVESTMENT BY HUIZENGA GROUP
                  GROUP OPTS FOR MAXIMUM $44 MILLION INVESTMENT

DALLAS - April 10, 2000 - ZixIt Corporation (Nasdaq: ZIXI) announced today that
a group of investors led by H. Wayne Huizenga has opted to invest the maximum
$44 million amount available under the investment arrangement previously
announced on March 23, 2000.

The Huizenga Group will purchase 916,667 shares of common stock for $44 million,
or $48.00 per share, which reflects a premium of $1.25 per share over the
ten-day average closing price of the stock on March 1, the day before the
conditional arrangement was agreed in principle. Additionally, the Huizenga
Group will receive 10-year warrants to purchase an additional 916,667 shares at
a price of $57.60 per share, a 23% premium over the 10-day average closing
price.

The Huizenga Group includes H. Wayne Huizenga, as well as a number of senior
executives from both Huizenga-related and non-related companies.

In connection with the transaction, David P. Cook, chairman and chief executive
officer of ZixIt Corporation, will reallocate 1,222,223 of his personal option
shares in the company to the investor group. This will be the second time that
Mr. Cook has contributed a portion of his personal shareholdings for the
long-term benefit of the company and its shareholders. As previously announced,
Mr. Cook reallocated approximately 254,000 option shares to internal ZixIt
personnel, primarily technical employees. Mr. Cook retains approximately 2.5
million option shares.

The completion of this transaction is subject to definitive agreements and the
approval of ZixIt Corporation's board of directors.
