                        WARRANT TO PURCHASE COMMON STOCK

Warrant No.:                                        Number of Shares:
             -----------------------                                  ---------
Date of Issuance: _____________ __, 2002

InterVoice-Brite, Inc., a Texas corporation (the "COMPANY"), hereby certifies
that, for Ten United States Dollars ($10.00) and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged,
____________________, the registered holder hereof or its permitted assigns, is
entitled, subject to the terms set forth below, to purchase from the Company
upon surrender of this Warrant, at any time or times on or after the date
hereof, but not after 11:59 P.M. New York Time on the Expiration Date (as
defined herein) ________________ ( ) [INSERT THE QUOTIENT OF (A) 25% OF THE
PRINCIPAL AMOUNT OF NOTES PURCHASED BY THE HOLDER, DIVIDED BY (B) THE WARRANT
EXERCISE PRICE] fully paid nonassessable shares of Common Stock (as defined
herein) of the Company (the "WARRANT SHARES") at the purchase price per share
provided in Section 1(b) below; provided, however, that in no event shall the
holder be entitled to exercise this Warrant for a number of Warrant Shares in
excess of that number of Warrant Shares which, upon giving effect to such
exercise, would cause the aggregate number of shares of Common Stock
beneficially owned by the holder and its affiliates to exceed 4.99% of the
outstanding shares of the Common Stock following such exercise. For purposes of
the foregoing proviso, the aggregate number of shares of Common Stock
beneficially owned by the holder and its affiliates shall include the number of
shares of Common Stock issuable upon exercise of this Warrant with respect to
which the determination of such proviso is being made, but shall exclude shares
of Common Stock which would be issuable upon (i) exercise of the remaining,
unexercised Warrants beneficially owned by

<PAGE>

the holder and its affiliates and (ii) exercise, conversion or exchange of the
unexercised, unconverted or unexchanged portion of any other securities of the
Company beneficially owned by the holder and its affiliates (including, without
limitation, any convertible notes or preferred stock) subject to a limitation on
conversion, exercise or exchange analogous to the limitation contained herein.
Except as set forth in the preceding sentence, for purposes of this paragraph,
beneficial ownership shall be calculated in accordance with Section 13(d) of the
Securities Exchange Act of 1934, as amended. For purposes of this Warrant, in
determining the number of outstanding shares of Common Stock a holder may rely
on the number of outstanding shares of Common Stock as reflected in (1) the
Company's most recent Form 10-Q or Form 10-K, as the case may be, (2) a more
recent public announcement by the Company or (3) any other notice by the Company
or its transfer agent setting forth the number of shares of Common Stock
outstanding. Upon the written request of any holder, the Company shall promptly,
but in no event later than one (1) Business Day following the receipt of such
notice, confirm in writing to any such holder the number of shares of Common
Stock then outstanding. In any case, the number of outstanding shares of Common
Stock shall be determined after giving effect to the conversion, exercise or
exchange of securities of the Company, including the Notes (as defined below)
and the SPA Warrants (as defined below), since the date as of which such number
of outstanding shares of Common Stock was reported.

<PAGE>

         period beginning at 9:30 a.m., New York City Time (or such other time
         as the Principal Market publicly announces is the official open of
         trading), and ending at 4:00 p.m., New York City Time (or such other
         time as the Principal Market publicly announces is the official close
         of trading), as reported by Bloomberg through its "Volume at Price"
         functions or, if the foregoing does not apply, the dollar
         volume-weighted average price of such security in the over-the-counter
         market on the electronic bulletin board for such security during the
         period beginning at 9:30 a.m., New York City Time (or such other time

         such security on such date shall be the fair market value as mutually
         determined by the Company and the holders of the SPA Warrants
         representing a majority of the shares of Common Stock issuable upon
         exercise of the SPA Warrants then outstanding. If the Company and the
         holders of the SPA Warrants representing a majority of the shares of
         Common Stock issuable upon exercise of the SPA Warrants then
         outstanding are unable to agree upon the fair market value of the
         Common Stock, then such dispute shall be resolved pursuant to Section
         2(a) below. All such determinations to be appropriately adjusted for
         any stock dividend, stock split, stock combination or other similar
         transaction during such period.

         Section 2. Exercise of Warrant.

                  (a) Subject to the terms and conditions hereof, this Warrant
may be exercised by the holder hereof then registered on the books of the
Company, in whole or in part, at any time on any Business Day on or after the
opening of business on the date hereof and prior to 11:59 P.M. New York Time on
the Expiration Date by (i) delivery of a written notice, in the form of the
subscription form attached as Exhibit A hereto (the "EXERCISE NOTICE"), of such
holder's election to exercise this Warrant, which notice shall specify the
number of Warrant Shares to be purchased, (ii) (A) payment to the Company of an
amount equal to the Warrant Exercise Price multiplied by the number of Warrant
Shares as to which this Warrant is being exercised (the "AGGREGATE EXERCISE
PRICE") by wire transfer of immediately available funds (or by check if the
Company has not provided the holder of this Warrant with wire transfer
instructions for such payment) or (B) by notifying the Company that this Warrant
is being exercised pursuant to a Cashless Exercise (as defined in and if
permitted by Section 2(e)), and (iii) the surrender to a common carrier for
overnight delivery to the Company as soon as practicable following such date,
this Warrant (or an indemnification undertaking reasonably acceptable to the
Company with respect to this Warrant in the case of its loss, theft or
destruction); provided, that if such Warrant Shares are to be issued in any name
other than that of the registered holder of this Warrant, such issuance shall be
deemed a transfer and the provisions of Section 7 shall be applicable. In the
event of any exercise of the rights represented by this Warrant in compliance
with this Section 2(a), the Company shall on the second (2nd) Business Day (the

                                       -4-

<PAGE>

"WARRANT SHARE DELIVERY DATE") following the date of its receipt of the Exercise
Notice, the Aggregate Exercise Price (or notice of Cashless Exercise) and this
Warrant (or an indemnification undertaking with respect to this Warrant in the
case of its loss, theft or destruction) (the "EXERCISE DELIVERY DOCUMENTS") (A)
provided that the transfer agent is participating in The Depository Trust
Company ("DTC") Fast Automated Securities Transfer Program and provided that the
holder is eligible to receive shares through DTC, credit such aggregate number
of shares of Common Stock to which the holder shall be entitled to the holder's
or its designee's balance account with DTC through its Deposit Withdrawal Agent
Commission system or (B) issue and deliver to the address specified in the
Exercise Notice, a certificate, registered in the name of the holder or its
designee, for the number of shares of Common Stock to which the holder shall be
entitled. Upon (x) delivery of the Exercise Notice and (y) the Aggregate
Exercise Price referred to in clause (ii)(A) above or notification to the
Company of a Cashless Exercise referred to in Section 2(e), the holder of this
Warrant shall be deemed for all corporate purposes to have become the holder of
record of the Warrant Shares with respect to which this Warrant has been
exercised, irrespective of the date of delivery of this Warrant as required by
clause (iii) above or the certificates evidencing such Warrant Shares. In the
case of a dispute as to the determination of the Warrant Exercise Price, the
Weighted Average Price of a security or the arithmetic calculation of the number
of Warrant Shares, the Company shall promptly issue to the holder the number of
shares of Common Stock that is not disputed and shall submit the disputed
determinations or arithmetic calculations to the holder via facsimile within one
(1) Business Day of receipt of the holder's Exercise Notice. If the holder and
the Company are unable to agree upon the determination of the Warrant Exercise
Price, the Weighted Average Price or arithmetic calculation of the number of
Warrant Shares within one (1) Business Day of such disputed determination or
arithmetic calculation being submitted to the holder, then the Company shall
within two (2) Business Days submit via facsimile (i) the disputed determination
of the Warrant Exercise Price or the Weighted Average Price to an independent,
reputable investment banking firm or (ii) the disputed arithmetic calculation of
the number of Warrant Shares to its independent, outside accountant. The Company
shall cause the investment banking firm or the accountant, as the case may be,
to perform the determinations or calculations and notify the Company and the
holder of the results no later than three (3) Business Days from the time it
receives the disputed determinations or calculations. Such investment banking
firm's or accountant's determination or calculation, as the case may be, shall
be deemed conclusive absent error.

                  (b) Unless the rights represented by this Warrant shall have
expired or shall have been fully exercised, the Company shall, as soon as
practicable and in no event later than five (5) Business Days after receipt of
the Exercise Delivery Documents (the "WARRANT DELIVERY DATE") and at its own
expense, issue a new Warrant identical in all respects to this Warrant exercised
except it shall represent rights to purchase the number of Warrant Shares
purchasable immediately prior to such exercise under this Warrant, less the
number of Warrant Shares with respect to which such Warrant is exercised.

                  (c) No fractional shares of Common Stock are to be issued upon
the exercise of this Warrant, but rather the number of shares of Common Stock
issued upon exercise of this Warrant shall be rounded up or down to the nearest
whole number.

                                       -5-

<PAGE>

                  (d) If the Company shall fail for any reason or for no reason
(x) to issue and deliver to the holder within three (3) Business Days of receipt
of the Exercise Delivery Documents a certificate for the number of shares of
Common Stock to which the holder is entitled or to credit the holder's balance
account with DTC for such number of shares of Common Stock to which the holder
is entitled upon the holder's exercise of this Warrant or (y) to issue and
deliver to the holder within five (5) Business Days of receipt of the Exercise
Delivery Documents a new Warrant for the number of shares of Common Stock to
which such holder is entitled pursuant to Section 2(b) hereof, then the Company
shall, in addition to any other remedies under this Warrant or the Securities
Purchase Agreement or otherwise available to such holder, including any
indemnification under Section 8 of the Securities Purchase Agreement, pay as
additional damages in cash to such holder on each day after such third (3rd)
Business Day that such shares of Common Stock are not issued and delivered to
the holder, in the case of clause (x) above, or such fifth (5th) Business Day
that such Warrant is not delivered, in the case of clause (y) above, in an
amount equal to 0.5% of the sum of (i) the product of (A) the number of shares
of Common Stock not issued to the holder on or prior to the Warrant Share
Delivery Date and (B) the Weighted Average Price of the Common Stock on the
Warrant Share Delivery Date, in the case of the failure to deliver Common Stock,
and (ii) if the Company has failed to deliver a Warrant to the holder on or
prior to the Warrant Delivery Date, the product of (x) the number of shares of
Common Stock issuable upon exercise of the Warrant as of the Warrant Delivery
Date, and (y) the Weighted Average Price of the Common Stock on the Warrant
Delivery Date, in the case of the failure to deliver a Warrant; provided that in
no event shall cash damages accrue pursuant to this Section 2(d) during the
period, if any, in which any Warrant Shares are the subject of a bona fide
dispute which is subject to and being resolved pursuant to, and in compliance
with the time periods and other provisions of, the dispute resolution provisions
of Section 2(a). Alternatively, subject to the dispute resolution provisions of
Section 2(a), at the election of the holder made in the holder's sole
discretion, the Company shall pay to the holder, in lieu of the additional
damages referred to in the preceding sentence (but in addition to all other
available remedies which the holder may pursue hereunder and under the
Securities Purchase Agreement (including indemnification pursuant to Section 8
thereof)), 110% of the amount by which (A) the holder's total purchase price
(including brokerage commissions, if any) for shares of Common Stock purchased
to make delivery in satisfaction of a sale by such holder of the shares of
Common Stock to which the holder is entitled but has not received upon an
exercise, exceeds (B) the net proceeds received by the holder from the sale of
the shares of Common Stock to which the holder is entitled but has not received
upon such exercise.

                  (e) If, despite the Company's obligations under the Securities
Purchase Agreement and the Registration Rights Agreement, the Warrant Shares to
be issued are not registered and available for resale pursuant to a registration
statement in accordance with the Registration Rights Agreement, including during
a Grace Period (as defined in the Registration Rights Agreement), then
notwithstanding anything contained herein to the contrary, the holder of this
Warrant may, at its election exercised in its sole discretion, exercise this
Warrant in whole or in part and, in lieu of making the cash payment otherwise
contemplated to be made to the Company upon such exercise in payment of the
Aggregate Exercise Price, elect instead to receive upon such exercise the "Net
Number" of shares of Common Stock determined according to the following formula
(a "CASHLESS EXERCISE"):

                                       -6-

<PAGE>

         Net Number = (A x B) - (A x C)
                      -----------------
                             B
                  For purposes of the foregoing formula:

                           A = the total number of shares with respect to which
                           this Warrant is then being exercised.

                           B = the Weighted Average Price of the Common Stock on
                           the trading day immediately preceding the date of the
                           delivery of the Exercise Notice.

                           C = the Warrant Exercise Price then in effect for the
                           applicable Warrant Shares at the time of such
                           exercise.

         Section 3. Covenants as to Common Stock. The Company hereby covenants
and agrees as follows:

                  (a) This Warrant is, and any Warrants issued in substitution
for or replacement of this Warrant will upon issuance be, duly authorized and
validly issued.

                  (b) All Warrant Shares which may be issued upon the exercise
of the rights represented by this Warrant will, upon issuance, be validly
issued, fully paid and nonassessable and free from all taxes, liens and charges
with respect to the issue thereof.

                  (c) During the period within which the rights represented by
this Warrant may be exercised, the Company will at all times have authorized and
reserved at least 100% of the number of shares of Common Stock needed to provide
for the exercise of the rights then represented by this Warrant and the par
value of said shares will at all times be less than or equal to the applicable
Warrant Exercise Price.

                  (d) The Company shall promptly secure the listing of the
shares of Common Stock issuable upon exercise of this Warrant upon each national
securities exchange or automated quotation system, if any, upon which shares of
Common Stock are then listed (subject to official notice of issuance upon
exercise of this Warrant) and shall maintain, so long as any other shares of
Common Stock shall be so listed, such listing of all shares of Common Stock from
time to time issuable upon the exercise of this Warrant; and the Company shall
so list on each national securities exchange or automated quotation system, as
the case may be, and shall maintain such listing of, any other shares of capital
stock of the Company issuable upon the exercise of this Warrant if and so long
as any shares of the same class shall be listed on such national securities
exchange or automated quotation system.

                  (e) The Company will not, by amendment of its Articles of
Incorporation or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of

                                       -7-

<PAGE>

securities, or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms to be observed or performed by it hereunder,
but will at all times in good faith assist in the carrying out of all the
provisions of this Warrant and in the taking of all such action as may
reasonably be requested by the holder of this Warrant in order to protect the
exercise privilege of the holder of this Warrant against dilution or other
impairment, consistent with the tenor and purpose of this Warrant. Without
limiting the generality of the foregoing, the Company (i) will not increase the
par value of any shares of Common Stock receivable upon the exercise of this
Warrant above the Warrant Exercise Price then in effect, and (ii) will take all
such actions as may be necessary or appropriate in order that the Company may
validly and legally issue fully paid and nonassessable shares of Common Stock
upon the exercise of this Warrant.

                  (f) This Warrant will be binding upon any entity succeeding to
the Company by merger, consolidation or acquisition of all or substantially all
of the Company's assets.

         Section 4. Taxes. The Company shall pay any and all taxes which may be
payable with respect to the issuance and delivery of Warrant Shares upon
exercise of this Warrant.

         Section 5. Warrant Holder Not Deemed a Stockholder. Except as otherwise
specifically provided herein, no holder, as such, of this Warrant shall be
entitled to vote or receive dividends or be deemed the holder of shares of the
Company for any purpose (other than to the extent that the holder is deemed to
be a beneficial holder of shares under applicable securities laws after taking
into account the limitation set forth in the first paragraph of this Warrant),
nor shall anything contained in this Warrant be construed to confer upon the
holder hereof, as such, any of the rights of a stockholder of the Company or any
right to vote, give or withhold consent to any corporate action (whether any
reorganization, issue of stock, reclassification of stock, consolidation,
merger, conveyance or otherwise), receive notice of meetings, receive dividends
or subscription rights, or otherwise, prior to the issuance to the holder of
this Warrant of the Warrant Shares which he or she is then entitled to receive
upon the due exercise of this Warrant. In addition, nothing contained in this
Warrant shall be construed as imposing any liabilities on such holder to
purchase any securities (upon exercise of this Warrant or otherwise) or as a
stockholder of the Company, whether such liabilities are asserted by the Company
or by creditors of the Company. Notwithstanding this Section 5, the Company will
provide the holder of this Warrant with copies of the same notices and other
information given to the stockholders of the Company generally,
contemporaneously with the giving thereof to the stockholders.

         Section 6. Representations of Holder. The holder of this Warrant, by
the acceptance hereof, represents that it is acquiring this Warrant, and upon
exercise hereof (other than pursuant to a Cashless Exercise) will acquire the
Warrant Shares, for its own account and not with a view towards, or for resale
in connection with, the public sale or distribution of this Warrant or the
Warrant Shares, except pursuant to sales registered or exempted under the
Securities Act; provided, however, that by making the representations herein,
the holder does not agree to hold this Warrant or any of the Warrant Shares for
any minimum or other specific term and reserves the right to dispose of this
Warrant and the Warrant Shares at any time in accordance with or pursuant to a
registration statement or an exemption under the Securities Act. The holder of
this Warrant further

                                       -8-

<PAGE>

represents, by acceptance hereof, that, as of this date, such holder is an
"accredited investor" as such term is defined in Rule 501(a)(3) of Regulation D
promulgated by the Securities and Exchange Commission under the Securities Act
(an "ACCREDITED INVESTOR"). Each delivery of an Exercise Notice, other than in
connection with a Cashless Exercise shall constitute confirmation at such time
by the holder of the representations concerning the Warrant Shares set forth in
the first two sentences of this Section 6, unless contemporaneous with the
delivery of such Exercise Notice the holder notifies the Company in writing that
it is not making such representations (a "REPRESENTATION NOTICE"). If the holder
delivers a Representation Notice in connection with an exercise, it shall be a
condition to such holder's exercise of this Warrant and the Company's
obligations set forth in Section 2 in connection with such exercise, that the
Company receive such other representations as the Company considers reasonably
necessary to assure the Company that the issuance of its securities upon
exercise of this Warrant shall not violate any United States or state securities
laws.

         Section 7. Ownership and Transfer.

                  (a) The Company shall maintain at its principal executive
offices (or such other office or agency of the Company as it may designate by
notice to the holder hereof), a register for this Warrant, in which the Company
shall record the name and address of the person in whose name this Warrant has
been issued, as well as the name and address of each transferee. The Company may
treat the person in whose name any Warrant is registered on the register as the
owner and holder thereof for all purposes, notwithstanding any notice to the
contrary, but in all events recognizing any transfers made in accordance with
the terms of this Warrant.

                  (b) The holder of this Warrant may assign or transfer some or
all of its rights hereunder, subject to compliance with the 1933 Act and the
provisions of Section 2(f) of the Securities Purchase Agreement, (i) to a
Permitted Transferee (as defined below) without the consent of the Company and
(ii) to a Person which is not a Permitted Transferee with the prior consent of
the Company, which consent shall not be unreasonably withheld. For purposes of
this Section 7(b), a "PERMITTED TRANSFEREE" means: (i) a Buyer (as defined in
the Securities Purchase Agreement); (ii) an Affiliate (as defined below) of the
holder of this Warrant; (iii) a holder of Notes or Warrants; (iv) an Affiliate
of a holder of Notes or Warrants; (v) any entity which has the same investment
advisor or manager or trading advisor or manager as any of the Persons described
in the immediately preceding clauses (i) through (iv); (vi) a pledgee (or a
transferee of such pledgee) in connection with a bona fide margin account or
other loan or financing arrangement secured by this Warrant if such pledgee
seeks to enforce or realize such pledge; and (vii) any fund, financial
institution or entity with assets, or assets under management, of at least
$100,000,000. "AFFILIATE" for purposes of this Section 7(b) means, with respect

more equity interest in that Person, (B) has a 25% or more common ownership with
that Person, (C) controls that Person, (D) is controlled by that Person, or (E)
is under common control with that person or entity. "CONTROL" or "CONTROLS" for
purposes of this Section 7(b) means that a Person has the power, directly or
indirectly, to conduct or govern the policies of another Person.

                  (c) The Company is obligated to register the Warrant Shares
for resale under the Securities Act pursuant to the Registration Rights
Agreement and the initial holder of this Warrant

                                       -9-

<PAGE>

(and certain assignees thereof) is entitled to the registration rights in
respect of the Warrant Shares as set forth in the Registration Rights Agreement.

         Section 8. Adjustment of Warrant Exercise Price and Number of Shares.
The Warrant Exercise Price and the number of shares of Common Stock issuable
upon exercise of this Warrant shall be adjusted from time to time as follows:

                  (a) Adjustment of Warrant Exercise Price and Number of Shares
upon Issuance of Common Stock. If and whenever on or after the date of issuance
of this Warrant, the Company issues or sells, or is deemed to have issued or
sold, any shares of Common Stock (including the issuance or sale of shares of
Common Stock owned or held by or for the account of the Company, but excluding
(I) shares of Common Stock issued or deemed to have been issued by the Company
in connection with an Approved Stock Plan or a Future Approved Stock Plan, and
(II) shares of Common Stock issued or deemed to have been issued by the Company
upon conversion of the Notes or exercise of the SPA Warrants) for a
consideration per share less than a price (the "APPLICABLE PRICE") equal to the
Warrant Exercise Price in effect immediately prior to such issuance or sale,
then immediately after such issue or sale the Warrant Exercise Price then in
effect shall be reduced to an amount equal to such consideration per share. Upon
each such adjustment of the Warrant Exercise Price pursuant to the immediately
preceding sentence, the number of shares of Common Stock acquirable upon
exercise of this Warrant shall be adjusted to the number of shares determined by
multiplying the Warrant Exercise Price in effect immediately prior to such
adjustment by the number of shares of Common Stock acquirable upon exercise of
this Warrant immediately prior to such adjustment and dividing the product
thereof by the Warrant Exercise Price resulting from such adjustment.

                  (b) Effect on Warrant Exercise Price of Certain Events. For
purposes of determining the adjusted Warrant Exercise Price under Section 8(a)
above, the following shall be applicable (provided that any references to
"Common Stock", "Options" or "Convertible Securities" in subparagraphs (i)
through (iii) below shall be deemed to exclude Common Stock, Options and
Convertible Securities issued or deemed to have been issued by the Company in
connection with an Approved Stock Plan or a Future Approved Stock Plan or upon
conversion of the Notes or exercise of the SPA Warrants):

                           (i) Issuance of Options. If the Company in any manner
         grants or sells any Options and the lowest price per share for which
         one share of Common Stock is issuable upon the exercise of any such
         Option or upon conversion, exchange or exercise of any Convertible
         Securities issuable upon exercise of any such Option is less than the
         Applicable Price, then such share of Common Stock shall be deemed to be
         outstanding and to have been issued and sold by the Company at the time
         of the granting or sale of such Option for such price per share. For
         purposes of this Section 8(b)(i), the "lowest price per share for which
         one share of Common Stock is issuable upon exercise of such Options or
         upon conversion, exchange or exercise of such Convertible Securities"
         shall be equal to the sum of the lowest amounts of consideration (if
         any) received or receivable by the Company with respect to any one
         share of Common Stock upon the granting or sale of the Option, upon
         exercise of the

                                      -10-

<PAGE>

         Option and upon conversion, exchange or exercise of any Convertible
         Security issuable upon exercise of such Option. No further adjustment
         of the Warrant Exercise Price shall be made upon the actual issuance of
         such Common Stock or of such Convertible Securities upon the exercise
         of such Options or upon the actual issuance of such Common Stock upon
         conversion, exchange or exercise of such Convertible Securities.

                           (ii) Issuance of Convertible Securities. If the
         Company in any manner issues or sells any Convertible Securities and
         the lowest price per share for which one share of Common Stock is
         issuable upon such conversion, exchange or exercise thereof is less
         than the Applicable Price, then such share of Common Stock shall be
         deemed to be outstanding and to have been issued and sold by the
         Company at the time of the issuance or sale of such Convertible
         Securities for such price per share. For the purposes of this Section
         8(b)(ii), the "lowest price per share for which one share of Common
         Stock is issuable upon such conversion, exchange or exercise" shall be
         equal to the sum of the lowest amounts of consideration (if any)
         received or receivable by the Company with respect to one share of
         Common Stock upon the issuance or sale of the Convertible Security and
         upon conversion, exchange or exercise of such Convertible Security. No
         further adjustment of the Warrant Exercise Price shall be made upon the
         actual issuance of such Common Stock upon conversion, exchange or
         exercise of such Convertible Securities, and if any such issue or sale
         of such Convertible Securities is made upon exercise of any Options for
         which adjustment of the Warrant Exercise Price had been or are to be
         made pursuant to other provisions of this Section 8(b), no further
         adjustment of the Warrant Exercise Price shall be made by reason of
         such issue or sale.

                           (iii) Change in Option Price or Rate of Conversion.
         If the purchase price or exercise price provided for in any Options,
         the additional consideration, if any, payable upon the issue,
         conversion, exchange or exercise of any Convertible Securities, or the
         rate at which any Options or Convertible Securities are convertible
         into or exchangeable or exercisable for Common Stock changes at any
         time, the Warrant Exercise Price in effect at the time of such change
         shall be adjusted to the Warrant Exercise Price which would have been
         in effect at such time had such Options or Convertible Securities
         provided for such changed purchase price, additional consideration or
         changed conversion rate, as the case may be, at the time initially
         granted, issued or sold and the number of shares of Common Stock
         acquirable hereunder shall be correspondingly readjusted. For purposes
         of this Section 8(b)(iii), if the terms of any Option or Convertible
         Security that was outstanding as of the date of issuance of this
         Warrant are changed in the manner described in the immediately
         preceding sentence, then such Option or Convertible Security and the
         Common Stock deemed issuable upon exercise, conversion or exchange
         thereof shall be deemed to have been issued as of the date of such
         change. No adjustment shall be made if such adjustment would result in
         an increase of the Warrant Exercise Price then in effect.

                                      -11-

<PAGE>

                  (c) Effect on Warrant Exercise Price of Certain Events. For
purposes of determining the adjusted Warrant Exercise Price under Sections 8(a)
and 8(b), the following shall be applicable:

                           (i) Calculation of Consideration Received. In case
         any Option is issued in connection with the issue or sale of other
         securities of the Company, together comprising one integrated
         transaction in which no specific consideration is allocated to such
         Options by the parties thereto, the Options will be deemed to have been
         issued for a consideration of $.01. If any Common Stock, Options or
         Convertible Securities are issued or sold or deemed to have been issued
         or sold for cash, the consideration received therefor will be deemed to
         be the net amount received by the Company therefor. If any Common
         Stock, Options or Convertible Securities are issued or sold for a
         consideration other than cash, the amount of such consideration
         received by the Company will be the fair value of such consideration,
         except where such consideration consists of marketable securities, in
         which case the amount of consideration received by the Company will be
         the Weighted Average Price of such securities on the date of receipt of
         such securities. If any Common Stock, Options or Convertible Securities
         are issued to the owners of the non-surviving entity in connection with
         any merger in which the Company is the surviving entity, the amount of
         consideration therefor will be deemed to be the fair value of such
         portion of the net assets and business of the non-surviving entity as
         is attributable to such Common Stock, Options or Convertible
         Securities, as the case may be. The fair value of any consideration
         other than cash or securities will be determined jointly by the Company
         and the holders of SPA Warrants representing a majority of the shares
         of Common Stock obtainable upon exercise of the SPA Warrants then
         outstanding. If such parties are unable to reach agreement within ten
         (10) days after the occurrence of an event requiring valuation (the
         "VALUATION EVENT"), the fair value of such consideration will be
         determined within five (5) Business Days after the tenth (10th) day
         following the Valuation Event by an independent, reputable appraiser
         jointly selected by the Company and the holders of SPA Warrants
         representing a majority of the shares of Common Stock obtainable upon
         exercise of the SPA Warrants then outstanding. The determination of
         such appraiser shall be final and binding upon all parties absent error
         and the fees and expenses of such appraiser shall be borne by the
         Company.

                           (ii) Record Date. If the Company takes a record of
         the holders of Common Stock for the purpose of entitling them (1) to
         receive a dividend or other distribution payable in Common Stock,
         Options or in Convertible Securities or (2) to subscribe for or
         purchase Common Stock, Options or Convertible Securities, then such
         record date will be deemed to be the date of the issue or sale of the
         shares of Common Stock deemed to have been issued or sold upon the
         declaration of such dividend or the making of such other distribution
         or the date of the granting of such right of subscription or purchase,
         as the case may be.

                  (d) Adjustment of Warrant Exercise Price upon Subdivision or
Combination of Common Stock. If the Company at any time after the date of
issuance of this Warrant subdivides (by any stock split, stock dividend,
recapitalization or otherwise) one or more classes of its

                                      -12-

<PAGE>

outstanding shares of Common Stock into a greater number of shares, the Warrant
Exercise Price in effect immediately prior to such subdivision will be
proportionately reduced and the number of shares of Common Stock obtainable upon
exercise of this Warrant will be proportionately increased. If the Company at
any time after the date of issuance of this Warrant combines (by combination,
reverse stock split or otherwise) one or more classes of its outstanding shares
of Common Stock into a smaller number of shares, the Warrant Exercise Price in
effect immediately prior to such combination will be proportionately increased
and the number of shares of Common Stock obtainable upon exercise of this
Warrant will be proportionately decreased. Any adjustment under this Section
8(d) shall become effective at the close of business on the date the subdivision
or combination becomes effective.

                  (e) Distribution of Assets. If the Company shall declare or
make any dividend or other distribution of its assets (or rights to acquire its
assets) to holders of Common Stock, by way of return of capital or otherwise
(including, without limitation, any distribution of cash, stock or other
securities, property or options by way of a dividend, spin off,
reclassification, corporate rearrangement or other similar transaction) (a
"DISTRIBUTION"), at any time after the issuance of this Warrant, then, in each
such case:

                           (i) the Warrant Exercise Price in effect immediately
         prior to the close of business on the record date fixed for the
         determination of holders of Common Stock entitled to receive the
         Distribution shall be reduced, effective as of the close of business on
         such record date, to a price determined by multiplying such Warrant
         Exercise Price by a fraction of which (A) the numerator shall be the
         Weighted Average Price of the Common Stock on the trading day
         immediately preceding such record date minus the value of the
         Distribution (as determined in good faith by the Company's Board of
         Directors) applicable to one share of Common Stock, and (B) the
         denominator shall be the Weighted Average Price of the Common Stock on
         the trading day immediately preceding such record date; and

                           (ii) either (A) the number of Warrant Shares
         obtainable upon exercise of this Warrant shall be increased to a number
         of shares equal to the number of shares of Common Stock obtainable
         immediately prior to the close of business on the record date fixed for
         the determination of holders of Common Stock entitled to receive the
         Distribution multiplied by the reciprocal of the fraction set forth in
         the immediately preceding clause (i), or (B) in the event that the
         Distribution is of common stock of a company whose common stock is
         traded on a national securities exchange or a national automated
         quotation system, then the holder of this Warrant shall receive an
         additional warrant to purchase Common Stock, the terms of which shall
         be identical to those of this Warrant, except that such warrant shall
         be exercisable into the amount of the assets that would have been
         payable to the holder of this Warrant pursuant to the Distribution had
         the holder exercised this Warrant immediately prior to such record date
         and with an exercise price equal to the amount by which the exercise
         price of this Warrant was decreased with respect to the Distribution
         pursuant to the terms of the immediately preceding clause (i).

                                      -13-

<PAGE>

                  (f) Certain Events. If any event occurs of the type
contemplated by the provisions of this Section 8 but not expressly provided for
by such provisions (including, without limitation, the granting of stock
appreciation rights, phantom stock rights or other rights with equity features),
then the Company's Board of Directors will make an appropriate adjustment in the
Warrant Exercise Price and the number of shares of Common Stock obtainable upon
exercise of this Warrant so as to protect the rights of the holders of the SPA
Warrants; provided that no such adjustment will increase the Warrant Exercise
Price or decrease the number of shares of Common Stock obtainable as otherwise
determined pursuant to this Section 8.

                  (g) Notices.

                           (i) Immediately upon any adjustment of the Warrant
         Exercise Price, the Company will give written notice thereof to the
         holder of this Warrant, setting forth in reasonable detail, and
         certifying, the calculation of such adjustment.

                           (ii) The Company will give written notice to the
         holder of this Warrant at least ten (10) days prior to the date on
         which the Company closes its books or takes a record (A) with respect
         to any dividend or distribution upon the Common Stock, (B) with respect
         to any pro rata subscription offer to holders of Common Stock or (C)
         for determining rights to vote with respect to any Organic Change (as
         defined below), dissolution or liquidation, provided that such
         information shall be made known to the public prior to or in
         conjunction with such notice being provided to such holder.

                           (iii) The Company will also give written notice to
         the holder of this Warrant at least ten (10) days prior to the date on
         which any Organic Change, dissolution or liquidation will take place,
         provided that such information shall be made known to the public prior
         to or in conjunction with such notice being provided to such holder.

         Section 9. Purchase Rights; Reorganization, Reclassification,
Consolidation, Merger or Sale. (a) In addition to any adjustments pursuant to
Section 8 above, if at any time the Company grants, issues or sells any Options,
Convertible Securities or rights to purchase stock, warrants, securities or
other property pro rata to the record holders of any class of Common Stock (the
"PURCHASE RIGHTS"), then the holder of this Warrant will be entitled to acquire,
upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights
which such holder could have acquired if such holder had held the number of
shares of Common Stock acquirable upon complete exercise of this Warrant
immediately before the date on which a record is taken for the grant, issuance
or sale of such Purchase Rights, or, if no such record is taken, the date as of
which the record holders of Common Stock are to be determined for the grant,
issue or sale of such Purchase Rights.

                  (b) Any recapitalization, reorganization, reclassification,
consolidation, merger, sale of all or substantially all of the Company's assets
to another Person or other transaction which is effected in such a way that
holders of Common Stock are entitled to receive (either directly or

                                      -14-

<PAGE>

upon subsequent liquidation) stock, securities or assets with respect to or in
exchange for Common Stock is referred to herein as "ORGANIC CHANGE." Prior to
the consummation of any (i) sale of all or substantially all of the Company's
assets to an acquiring Person or (ii) other Organic Change following which the
Company is not a surviving entity, the Company will secure from the Person
purchasing such assets or the successor resulting from such Organic Change (in
each case, the "ACQUIRING ENTITY") a written agreement (in form and substance
satisfactory to the holders of SPA Warrants representing a majority of the
shares of Common Stock obtainable upon exercise of the SPA Warrants then
outstanding) to deliver to each holder of SPA Warrants in exchange for such SPA
Warrants, a security of the Acquiring Entity evidenced by a written instrument
substantially similar in form and substance to this Warrant and satisfactory to
the holders of the SPA Warrants (including, an adjusted warrant exercise price
equal to the value for the Common Stock reflected by the terms of such
consolidation, merger or sale, and exercisable for a corresponding number of
shares of Common Stock acquirable and receivable upon exercise of the SPA
Warrants (without regard to any limitations on exercises), if the value so
reflected is less than the Warrant Exercise Price in effect immediately prior to
such consolidation, merger or sale). Prior to the consummation of any other
Organic Change, the Company shall make appropriate provision (in form and
substance satisfactory to the holders of SPA Warrants representing a majority of
the shares of Common Stock obtainable upon exercise of the SPA Warrants then
outstanding) to insure that each of the holders of the SPA Warrants will
thereafter have the right to acquire and receive in lieu of or in addition to
(as the case may be) the shares of Common Stock immediately theretofore
acquirable and receivable upon the exercise of such holder's SPA Warrants
(without regard to any limitations on exercises), such shares of stock,
securities or assets that would have been issued or payable in such Organic
Change with respect to or in exchange for the number of shares of Common Stock
which would have been acquirable and receivable upon the exercise of such
holder's Warrant as of the date of such Organic Change (without taking into
account any limitations or restrictions on the exerciseability of this Warrant).

         Section 10. Lost, Stolen, Mutilated or Destroyed Warrant. If this
Warrant is lost, stolen, mutilated or destroyed, the Company shall promptly, on
receipt of an indemnification reasonably satisfactory to the Company (or in the
case of a mutilated Warrant, the Warrant), issue a new Warrant of like
denomination and tenor as this Warrant so lost, stolen, mutilated or destroyed.

         Section 11. Notice. Any notices, consents, waivers or other
communications required or permitted to be given under the terms of this Warrant
must be in writing and will be deemed to have been delivered: (i) upon receipt,
when delivered personally; (ii) upon receipt, when sent by facsimile (provided

         Section 12. Limitation on Number of Warrant Shares. The Company shall
not be obligated to issue any Warrant Shares upon exercise of this Warrant if
the issuance of such shares of Common Stock would exceed that number of shares
of Common Stock which the Company may issue upon exercise of this Warrant (the
"EXCHANGE CAP") without breaching the Company's obligations under the rules or
regulations of the Principal Market, except that such limitation shall not apply
in the event that the Company (a) obtains the approval of its stockholders as
required by the applicable rules of the Principal Market (or any successor rule
or regulation) for issuances of Common Stock in excess of such amount or (b)
obtains a written opinion from outside counsel to the Company that such approval
is not required, which opinion shall be reasonably satisfactory to

                                      -16-

the holders of SPA Warrants representing a majority of the Warrant Shares then
issuable upon exercise of outstanding SPA Warrants. Until such approval or
written opinion is obtained, the holder of this Warrant shall not be issued,
upon exercise of this Warrant, Warrant Shares in an amount greater than such
holder's Cap Allocation Amount (as defined in the Notes). In the event the
Company is prohibited from issuing Warrant Shares as a result of the operation
of this Section 12, the Company shall redeem for cash the portion of this
Warrant with respect to which Warrant Shares which cannot be issued as a result
of this Section 12, at a price per Warrant Share equal to the difference between
the Weighted Average Price and the Warrant Exercise Price of such Warrant Shares
as of the date of the attempted exercise.

         Section 13. Date. The date of this Warrant is May __, 2002 (the

effect after 11:59 P.M. New York Time on the Expiration Date, except that
notwithstanding any other provisions hereof, the provisions of Section 7 shall
continue in full force and effect after such date as to any Warrant Shares or
other securities issued upon the exercise of this Warrant.

         Section 14. Amendment and Waiver. Except as otherwise provided herein,
the provisions of the SPA Warrants may be amended and the Company may take any
action herein prohibited, or omit to perform any act herein required to be
performed by it, only if the Company has obtained the written consent of the
holders of SPA Warrants representing a majority of the shares of Common Stock
obtainable upon exercise of the SPA Warrants then outstanding; provided that no
such action may increase the Warrant Exercise Price of the SPA Warrants or
decrease the number of shares or class of stock obtainable upon exercise of any
SPA Warrants without the written consent of the holder of such SPA Warrant.

         Section 15. Descriptive Headings; Governing Law. The descriptive
headings of the several sections and paragraphs of this Warrant are inserted for
convenience only and do not constitute a part of this Warrant. All questions
concerning the construction, validity, enforcement and interpretation of this
Warrant shall be governed by the internal laws of the State of New York, without
giving effect to any choice of law or conflict of law provision or rule (whether
of the State of New York or any other jurisdiction) that would cause the
application of the laws of any jurisdiction other than the State of New York.

                          REGISTRATION RIGHTS AGREEMENT

         REGISTRATION RIGHTS AGREEMENT (this "AGREEMENT"), dated as of May 29,
2002, by and among InterVoice-Brite, Inc., a Texas corporation, with
headquarters located at 17811 Waterview Parkway, Dallas, Texas 75252 (the

         WHEREAS:

         A. In connection with the Securities Purchase Agreement by and among
the parties hereto of even date herewith (the "SECURITIES PURCHASE AGREEMENT"),
the Company has agreed, upon the terms and subject to the conditions of the
Securities Purchase Agreement, to issue and sell to the Buyers (i) convertible
notes of the Company (including accrued and unpaid interest thereon, the

no par value per share (the "COMMON STOCK") (as converted, the "CONVERSION
SHARES"), in accordance with the terms of the Notes, and (ii) warrants to
purchase shares of Common Stock (the "WARRANTS," and as exercised, the "WARRANT
SHARES");

         B. To induce the Buyers to execute and deliver the Securities Purchase
Agreement, the Company has agreed to provide certain registration rights under
the Securities Act of 1933, as amended, and the rules and regulations
thereunder, or any similar successor statute (collectively, the "1933 ACT"), and
applicable state securities laws.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants contained herein and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the Company and each
of the Buyers hereby agree as follows:

         1. DEFINITIONS.

                  As used in this Agreement, the following terms shall have the
following meanings:

                  a. "INVESTOR" means a Buyer, any transferee or assignee
thereof to whom a Buyer assigns its rights under this Agreement and who agrees
to become bound by the provisions of this Agreement in accordance with Section 9
and any transferee or assignee thereof to whom a transferee or assignee assigns
its rights under this Agreement and who agrees to become bound by the provisions
of this Agreement in accordance with Section 9.

                  b. "PERSON" means an individual, a limited liability company,
a partnership, a joint venture, a corporation, a trust, an unincorporated
organization and a governmental or any department or agency thereof.

                  c. "REGISTER," "REGISTERED," and "REGISTRATION" refer to a
registration effected by preparing and filing one or more Registration
Statements (as defined below) in compliance with

<PAGE>

the 1933 Act and pursuant to Rule 415 under the 1933 Act or any successor rule
providing for offering securities on a continuous or delayed basis ("RULE 415"),
and the declaration or ordering of effectiveness of such Registration
Statement(s) by the United States Securities and Exchange Commission (the
"SEC").

                  d. "REGISTRABLE SECURITIES" means (i) the Conversion Shares
issued or issuable upon conversion of the Notes, (ii) the Warrant Shares issued
or issuable upon exercise of the Warrants and (iii) any shares of capital stock
issued or issuable with respect to the Conversion Shares, the Notes, the Warrant
Shares and the Warrants as a result of any stock split, stock dividend,
recapitalization, exchange or similar event or otherwise, without regard to any
limitations on conversions of Notes or exercises of Warrants.

                  e. "REGISTRATION STATEMENT" means a registration statement or
registration statements of the Company filed under the 1933 Act covering the
Registrable Securities.

Capitalized terms used herein and not otherwise defined herein shall have the
respective meanings set forth in the Securities Purchase Agreement.

         2. REGISTRATION.

                  a. Mandatory Registration.

                           (i) Mandatory Registration. The Company shall
         prepare, and, as soon as practicable but in no event later than 15 days
         after the Closing Date (as defined in the Securities Purchase
         Agreement) (the "FILING DEADLINE"), file with the SEC a Registration
         Statement on Form S-3 covering the resale of all of the Registrable
         Securities. In the event that Form S-3 is unavailable for such a
         registration, the Company shall use such other form as is available for
         such a registration, subject to the provisions of Section 2(d). The
         Registration Statement prepared pursuant hereto shall register for
         resale at least that number of shares of Common Stock equal to the sum
         of (x) the number of Warrant Shares issuable upon exercise of all the
         outstanding Warrants (without regard to any limitations on the exercise
         thereof) as of the second trading day immediately preceding the date
         the Registration Statement is declared effective by the SEC and (y)
         150% of the number of Conversion Shares issuable upon conversion of all
         the outstanding Notes (without regard to any limitations on the
         conversion thereof) as of the second trading day immediately preceding
         the date the Registration Statement is declared effective by the SEC
         (assuming solely for purposes of this determination conversion of the
         Notes at the lower of the then prevailing Fixed Conversion Price (as
         defined in the Notes) and 95% of the arithmetic average of the Weighted
         Average Price (as defined in the notes) of the Common Stock on each of
         the ten (10) consecutive trading days immediately preceding such date),
         subject to adjustment as provided in Section 2(e). The Company shall
         use its best efforts to have the Registration Statement declared
         effective by the SEC as soon as practicable, but in no event later than
         the date which is 120 days after the Closing Date (the "EFFECTIVENESS
         DEADLINE").

                                        2

<PAGE>

                  b. Allocation of Registrable Securities. The initial number of
Registrable Securities included in any Registration Statement and each increase
in the number of Registrable Securities included therein shall be allocated pro
rata among the Investors based on the number of Registrable Securities held by
each Investor at the time the Registration Statement covering such initial
number of Registrable Securities or increase thereof is declared effective by
the SEC. In the event that an Investor sells or otherwise transfers any of such
Investor's Registrable Securities, each transferee shall be allocated a pro rata
portion of the then remaining number of Registrable Securities included in such
Registration Statement for such transferor. Any shares of Common Stock included
in a Registration Statement and which remain allocated to any Person which
ceases to hold any Registrable Securities covered by such Registration Statement
shall be allocated to the remaining Investors, pro rata based on the number of
Registrable Securities then held by such Investors which are covered by such
Registration Statement.

                  c. Legal Counsel. Subject to Section 5 hereof, the Buyers
holding a majority of the Registrable Securities shall have the right to select
one legal counsel to review and oversee any offering pursuant to this Section 2
("LEGAL COUNSEL"), which shall be Katten Muchin Zavis Rosenman or such other
counsel as thereafter designated by the holders of a majority of the Registrable
Securities. The Company shall reasonably cooperate with Legal Counsel in
performing the Company's obligations under this Agreement.

                  d. Ineligibility for Form S-3. In the event that Form S-3 is
not available for the registration of the resale of Registrable Securities
hereunder, the Company shall (i) register the resale of the Registrable
Securities on another appropriate form reasonably acceptable to the holder of a
majority of the Registrable Securities and (ii) undertake to register the
Registrable Securities on Form S-3 as soon as such form is available, provided
that the Company shall maintain the effectiveness of the Registration Statement
then in effect until such time as a Registration Statement on Form S-3 covering
the Registrable Securities has been declared effective by the SEC.

                  e. Sufficient Number of Shares Registered. In the event the
number of shares available under a Registration Statement filed pursuant to
Section 2(a) is insufficient to cover all of the Registrable Securities required
to be covered by such Registration Statement or an Investor's allocated portion
of the Registrable Securities pursuant to Section 2(b), the Company shall amend
the Registration Statement, or file a new Registration Statement (on the short
form available therefor, if applicable), or both, so as to cover at least 100%
of the number of such Registrable Securities as of the trading day immediately
preceding the date of the filing of such amendment or new Registration
Statement, in each case, as soon as practicable, but in any event not later than
fifteen (15) days after the necessity therefor arises. The Company shall use its
best efforts to cause such amendment and/or new Registration Statement to become
effective as soon as practicable following the filing thereof. For purposes of
the foregoing provision, the number of shares available under a Registration
Statement shall be deemed "insufficient to cover all of the Registrable
Securities" if at any time the number of Registrable Securities issued or
issuable upon conversion of the Notes and exercise of the Warrants covered by
such Registration Statement is greater than the number of shares of Common Stock
available for resale under such Registration Statement. The calculation set
forth

                                        3

<PAGE>

in the foregoing sentence shall be made without regard to any limitations on the
conversion of the Notes or exercise of the Warrants and such calculation shall
assume that the Notes and the Warrants are then convertible and exercisable,
respectively, into shares of Common Stock at the then prevailing Conversion Rate
(as defined in the Notes) and Warrant Exercise Price (as defined in the
Warrants), respectively, if applicable.

                  f. Effect of Failure to File and Obtain and Maintain
Effectiveness of Registration Statement. If (i) a Registration Statement
covering all the Registrable Securities and required to be filed by the Company
pursuant to this Agreement is not (A) filed with the SEC on or before the Fling
Deadline or (B) declared effective by the SEC on or before the Effectiveness
Deadline or (ii) on any day after the Registration Statement has been declared
effective by the SEC sales of all the Registrable Securities required to be
included on such Registration Statement cannot be made (other than during an
Allowable Grace Period (as defined in Section 3(t))) pursuant to the
Registration Statement (including, without limitation, because of a failure to
keep the Registration Statement effective, to disclose such information as is
necessary for sales to be made pursuant to the Registration Statement or to
register sufficient shares of Common Stock), then, as partial relief for the
damages to any holder by reason of any such delay in or reduction of its ability
to sell the underlying shares of Common Stock (which remedy shall not be
exclusive of any other remedies available at law or in equity), the Company
shall pay to each holder of Notes an amount in cash equal to the product of (i)
the principal amount of the Notes held by each holder multiplied by (ii) the sum
of (A) 0.02, if the Registration Statement is not filed by the Filing Deadline,
plus (B) 0.02, if the Registration Statement is not declared effective by the
Effectiveness Deadline, plus, (C) the product of (I) 0.000667 multiplied by (II)
the sum (without duplication) of (x) the number of days after the Filing
Deadline that such Registration Statement is not filed with the SEC, plus (y)
the number of days after the applicable Effectiveness Deadline that the
Registration Statement is not declared effective by the SEC, plus (z) the number
of days after the Registration Statement has been declared effective by the SEC
that such Registration Statement is not available (other than during an
Allowable Grace Period) for the sale of at least all the Registrable Securities
required to be included on such Registration Statement pursuant to Section 2(e).
The payments to which a holder shall be entitled pursuant to this Section 2(f)
are referred to herein as "REGISTRATION DELAY PAYMENTS." Registration Delay
Payments shall be paid on the earlier of (I) the last day of the calendar month
during which such Registration Delay Payments are incurred and (II) the third
Business Day after the event or failure giving rise to the Registration Delay
Payments is cured. In the event the Company fails to make Registration Delay
Payments in a timely manner, such Registration Delay Payments shall bear
interest at the rate of 2.0% per month (prorated for partial months) until paid
in full.

         3. RELATED OBLIGATIONS.

                  At such time as the Company is obligated to file a
Registration Statement with the SEC pursuant to Section 2(a) or 2(e), the
Company will use its best efforts to effect the registration of the Registrable
Securities in accordance with the intended method of disposition thereof and,
pursuant thereto, the Company shall have the following obligations:

                                        4

<PAGE>

                  a. The Company shall promptly prepare and file with the SEC a
Registration Statement with respect to the applicable Registrable Securities
(but in no event later than the applicable Filing Deadline) and use its best
efforts to cause such Registration Statement relating to the Registrable
Securities to become effective as soon as practicable after such filing (but in
no event later than the applicable Effectiveness Deadline). The Company shall
keep each Registration Statement effective pursuant to Rule 415 at all times
until the earlier of (i) the date as of which the Investors may sell all of the
Registrable Securities covered by such Registration Statement without
restriction pursuant to Rule 144(k) (or successor thereto) promulgated under the
1933 Act or (ii) the date on which the Investors shall have sold all the
Registrable Securities covered by such Registration Statement (the "REGISTRATION
PERIOD"). Such Registration Statement (including any amendments or supplements
thereto and prospectuses contained therein) shall not contain any 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 light of the
circumstances in which they were made, not misleading (other than, with respect
to an Investor, such an untrue statement or omission which occurs in reliance
upon and in conformity with information furnished in writing to the Company by
such Investor expressly for use in connection with the preparation of such
Registration Statement). The term "best efforts" shall mean, among other things,
that the Company shall submit to the SEC, within two (2) Business Days after the
Company learns that no review of a particular Registration Statement will be
made by the staff of the SEC or that the staff has no further comments on the
Registration Statement, as the case may be, a request for acceleration of
effectiveness of such Registration Statement to a time and date not later than
48 hours after the submission of such request.

                  b. The Company shall prepare and file with the SEC such
amendments (including post-effective amendments) and supplements to a
Registration Statement and the prospectus used in connection with such
Registration Statement, which prospectus is to be filed pursuant to Rule 424
promulgated under the 1933 Act, as may be necessary to keep such Registration
Statement effective at all times during the Registration Period, and, during
such period, comply with the provisions of the 1933 Act with respect to the
disposition of all Registrable Securities of the Company covered by such
Registration Statement until such time as all of such Registrable Securities
shall have been disposed of in accordance with the intended methods of
disposition by the seller or sellers thereof as set forth in such Registration
Statement. In the case of amendments and supplements to a Registration Statement
which are required to be filed pursuant to this Agreement (including pursuant to
this Section 3(b)) by reason of the Company filing a report on Form 10-K, Form
10-Q or Form 8-K or any analogous report under the Securities Exchange Act of
1934, as amended (the "1934 ACT"), the Company shall have incorporated such
report by reference into the Registration Statement, if applicable, or shall
file such amendments or supplements with the SEC on the same day on which the
1934 Act report is filed which created the requirement for the Company to amend
or supplement the Registration Statement.

                  c. The Company shall (A) permit Legal Counsel to review and
comment upon (i) the initial Registration Statement at least seven (7) days
prior to its filing with the SEC and (ii) all other Registration Statements and
all amendments and supplements to all Registration Statements

                                        5

<PAGE>

(except for Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and
Current Reports on Form 8-K and any similar or successor reports) within a
reasonable number of days prior to their filing with the SEC, and (B) not file
any document, registration statement, amendment or supplement described in the
foregoing clause (A) in a form to which Legal Counsel reasonably objects. The
Company shall not submit a request for acceleration of the effectiveness of a
Registration Statement or any amendment or supplement thereto without the prior
approval of Legal Counsel, which consent shall not be unreasonably withheld. The
Company shall furnish to Legal Counsel, without charge, (i) promptly after the
same is prepared and filed with the SEC, one copy of any Registration Statement
and any amendment(s) thereto, including financial statements and schedules, and
all exhibits and (ii) upon the effectiveness of any Registration Statement, one
copy of the prospectus included in such Registration Statement and all
amendments and supplements thereto. The Company shall reasonably cooperate with
Legal Counsel in performing the Company's obligations pursuant to this Section
3.

                  d. The Company shall furnish to each Investor whose
Registrable Securities are included in any Registration Statement, without
charge, (i) promptly after the same is prepared and filed with the SEC, at least
one copy of such Registration Statement and any amendment(s) thereto, including
financial statements and schedules, all exhibits and each preliminary
prospectus, (ii) upon the effectiveness of any Registration Statement, ten (10)
copies of the prospectus included in such Registration Statement and all
amendments and supplements thereto (or such other number of copies as such
Investor may reasonably request) and (iii) such other documents, including
copies of any preliminary or final prospectus, as such Investor may reasonably
request from time to time in order to facilitate the disposition of the
Registrable Securities owned by such Investor.

                  e. The Company shall use its best efforts to (i) register and
qualify, unless an exemption from registration and qualification applies, the
resale by the Investors of the Registrable Securities covered by a Registration
Statement under such other securities or "blue sky" laws of all the states of
the United States, (ii) prepare and file in those jurisdictions, such amendments
(including post-effective amendments) and supplements to such registrations and
qualifications as may be necessary to maintain the effectiveness thereof during
the Registration Period, (iii) take such other actions as may be necessary to
maintain such registrations and qualifications in effect at all times during the
Registration Period, and (iv) take all other actions reasonably necessary or
advisable to qualify the Registrable Securities for sale in such jurisdictions;
provided, however, that the Company shall not be required in connection
therewith or as a condition thereto to (x) qualify to do business in any
jurisdiction where it would not otherwise be required to qualify but for this
Section 3(e), (y) subject itself to general taxation in any such jurisdiction,
or (z) file a general consent to service of process in any such jurisdiction.
The Company shall promptly notify Legal Counsel and each Investor who holds
Registrable Securities of the receipt by the Company of any notification with
respect to the suspension of the registration or qualification of any of the
Registrable Securities for sale under the securities or "blue sky" laws of any
jurisdiction in the United States or its receipt of actual notice of the
initiation or threatening of any proceeding for such purpose.

                  f. The Company shall notify Legal Counsel and each Investor in
writing of the happening of any event, as promptly as practicable after becoming
aware of such event, as a result of which the prospectus included in a
Registration Statement, as then in effect, includes an untrue statement of a
material fact or omission to state a material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading (provided that in no event shall such
notice contain any material, nonpublic information), and promptly prepare a
supplement or amendment to such Registration Statement to correct such untrue
statement or omission, and deliver ten (10) copies of such supplement or
amendment to Legal Counsel and each Investor (or such other number of copies as
Legal Counsel or such Investor may reasonably request). The Company shall also
promptly notify Legal Counsel and each Investor in writing (i) when a prospectus
or any prospectus supplement or post-effective amendment has been filed, and
when a Registration Statement or any post-effective amendment has become
effective (notification of such effectiveness shall be delivered to Legal
Counsel and each Investor by facsimile on the same day of such effectiveness and
by overnight mail), (ii) of any request by the SEC for amendments or supplements
to a Registration Statement or related prospectus or related information, and
(iii) of the Company's reasonable determination that a post-effective amendment
to a Registration Statement would be appropriate.

                  g. The Company shall use its best efforts to prevent the
issuance of any stop order or other suspension of effectiveness of a
Registration Statement, or the suspension of the qualification of any of the
Registrable Securities for sale in any jurisdiction and, if such an order or
suspension is issued, to obtain the withdrawal of such order or suspension at
the earliest possible moment and to notify Legal Counsel and each Investor who
holds Registrable Securities being sold of the issuance of such order and the
resolution thereof or its receipt of actual notice of the initiation or threat
of any proceeding for such purpose.

                  h. At the reasonable request (in the context of the securities
laws) of any Investor, the Company shall furnish to such Investor, on the date
of the effectiveness of the Registration Statement and thereafter from time to
time on such dates as an Investor may reasonably request (i) a letter, dated
such date, from the Company's independent certified public accountants in form
and substance as is customarily given by independent certified public
accountants to underwriters in an underwritten public offering, addressed to the
Investors, and (ii) an opinion, dated as of such date, of counsel representing
the Company for purposes of such Registration Statement, in form, scope and
substance as is customarily given in an underwritten public offering, addressed
to the Investors.

                  i. At the reasonable request (in the context of the securities
laws) of any Investor, the Company shall make available for inspection during
regular business hours by (i) any Investor, (ii) Legal Counsel and (iii) one
firm of accountants or other agents retained by the Investors (collectively, the
"INSPECTORS"), all pertinent financial and other records, and pertinent
corporate documents and properties of the Company (collectively, the "RECORDS"),
as shall be reasonably deemed necessary by each Inspector, and cause the
Company's officers, directors and employees to supply all information which any
Inspector may reasonably request; provided, however, that each

                                        7

<PAGE>

Inspector shall agree to hold in strict confidence and shall not make any
disclosure (except to an Investor) or use of any Record or other information
which the Company determines in good faith to be confidential, and of which
determination the Inspectors are so notified, unless (a) the disclosure of such
Records is necessary to avoid or correct a misstatement or omission in any
Registration Statement or is otherwise required under the 1933 Act, (b) the
release of such Records is ordered pursuant to a final, non-appealable subpoena
or order from a court or government body of competent jurisdiction, or (c) the
information in such Records has been made generally available to the public
other than by disclosure in violation of this or any other agreement of which
the Inspector has knowledge. Each Investor agrees that it shall, upon learning
that disclosure of such Records is sought in or by a court or governmental body
of competent jurisdiction or through other means, give prompt notice to the
Company and allow the Company, at its expense, to undertake appropriate action
to prevent disclosure of, or to obtain a protective order for, the Records
deemed confidential. Each Inspector which exercises its rights under this
Section 3(i) shall be obligated to execute a non- disclosure agreement
containing such reasonable terms as the Company may request. The fees and
expenses of the Inspectors shall be borne by the applicable Investor.

                  j. The Company shall hold in confidence and not make any
disclosure of information concerning an Investor provided to the Company unless
(i) disclosure of such information is necessary to comply with federal or state
securities laws, (ii) the disclosure of such information is necessary to avoid
or correct a misstatement or omission in any Registration Statement, (iii) the
release of such information is ordered pursuant to a subpoena or other final,
non- appealable order from a court or governmental body of competent
jurisdiction, or (iv) such information has been made generally available to the
public other than by disclosure in violation of this Agreement or any other
agreement. The Company agrees that it shall, upon learning that disclosure of
such information concerning an Investor is sought in or by a court or
governmental body of competent jurisdiction or through other means, give prompt
written notice to such Investor and allow such Investor, at the Investor's
expense, to undertake appropriate action to prevent disclosure of, or to obtain
a protective order for, such information.

                  k. The Company shall use its best efforts either to (i) cause
all the Registrable Securities covered by a Registration Statement to be listed
on each securities exchange on which securities of the same class or series
issued by the Company are then listed, if any, if the listing of such
Registrable Securities is then permitted under the rules of such exchange, or
(ii) secure designation and quotation of all the Registrable Securities covered
by the Registration Statement on the Nasdaq National Market System, or (iii) if,
despite the Company's best efforts to satisfy the preceding clause (i) or (ii),
the Company is unsuccessful in satisfying the preceding clause (i) or (ii), to
secure the inclusion for quotation on The Nasdaq SmallCap Market for such
Registrable Securities and, without limiting the generality of the foregoing, to
arrange for at least two market makers to register with the National Association
of Securities Dealers, Inc. ("NASD") as such with respect to such Registrable
Securities. The Company shall pay all fees and expenses in connection with
satisfying its obligation under this Section 3(k).

                                        8

<PAGE>

                  l. The Company shall cooperate with the Investors who hold
Registrable Securities being offered and, to the extent applicable, facilitate
the timely preparation and delivery of certificates (not bearing any restrictive
legend) representing the Registrable Securities to be offered pursuant to a
Registration Statement and enable such certificates to be in such denominations
or amounts, as the case may be, as the Investors may reasonably request and
registered in such names as the Investors may request.

                  m. The Company shall provide a transfer agent and registrar of
all such Registrable Securities not later than the effective date of the
applicable Registration Statement.

                  n. If requested by an Investor, the Company shall (i) as soon
as practicable incorporate in a prospectus supplement or post-effective
amendment such information as an Investor requests to be included therein
relating to the sale and distribution of Registrable Securities, including,
without limitation, information with respect to the number of Registrable
Securities being offered or sold, the purchase price being paid therefor and any
other terms of the offering of the Registrable Securities to be sold in such
offering; (ii) as soon as practicable make all required filings of such
prospectus supplement or post-effective amendment after being notified of the
matters to be incorporated in such prospectus supplement or post-effective
amendment; and (iii) as soon as practicable, supplement or make amendments to
any Registration Statement if reasonably requested by an Investor of such
Registrable Securities.

                  o. The Company shall use its best efforts to cause the
Registrable Securities covered by the applicable Registration Statement to be
registered with or approved by such other governmental agencies or authorities
in the United States as may be necessary to consummate the disposition of such
Registrable Securities.

                  p. The Company shall make generally available to its security
holders as soon as practical, but not later than 90 days after the close of the
period covered thereby, an earnings statement (in form complying with the
provisions of Rule 158 under the 1933 Act) covering a twelve-month period
beginning not later than the first day of the Company's fiscal quarter next
following the effective date of the Registration Statement.

                  q. The Company shall otherwise use its best efforts to comply
with all applicable rules and regulations of the SEC in connection with any
registration hereunder.

                  r. Within two (2) Business Days after a Registration Statement
which covers applicable Registrable Securities is ordered effective by the SEC,
the Company shall deliver, and shall cause legal counsel for the Company to
deliver, to the transfer agent for such Registrable Securities (with copies to
the Investors whose Registrable Securities are included in such Registration
Statement) confirmation that such Registration Statement has been declared
effective by the SEC in the form attached hereto as Exhibit A.

                                        9

<PAGE>

                  s. The Company shall take all other reasonable actions
necessary to expedite and facilitate disposition by Investors of Registrable
Securities pursuant to a Registration Statement.

                  t. Notwithstanding anything to the contrary in Section 3(f),
at any time after the applicable Registration Statement has been declared
effective by the SEC, the Company may delay the disclosure of material
non-public information concerning the Company the disclosure of which at the
time is not, in the good faith opinion of the Board of Directors of the Company
and its counsel, in the best interest of the Company and, in the opinion of
counsel to the Company, otherwise required (a "GRACE PERIOD"); provided, that
the Company shall promptly (i) notify the Investors in writing of the existence
of material non-public information giving rise to a Grace Period (provided that
in each notice the Company will not disclose the content of such material
non-public information to the Investors) and the date on which the Grace Period
will begin, and (ii) notify the Investors in writing of the date on which the
Grace Period ends; and, provided further, that no Grace Period shall exceed 15
consecutive days and during any 365 day period such Grace Periods shall not
exceed an aggregate of 30 days and the first day of any Grace Period must be at
least two (2) trading days after the last day of any prior Grace Period (an
"ALLOWABLE GRACE PERIOD"). For purposes of determining the length of a Grace
Period above, the Grace Period shall begin on and include the date the holders
receive the notice referred to in clause (i) and shall end on and include the
later of the date the holders receive the notice referred to in clause (ii) and
the date referred to in such notice. The provisions of 3(g) hereof shall not be
applicable during the period of any Allowable Grace Period. Upon expiration of
the Grace Period, the Company shall again be bound by the first sentence of
Section 3(f) with respect to the information giving rise thereto unless such
material non-public information is no longer applicable.

         4. OBLIGATIONS OF THE INVESTORS.

                  a. At least seven (7) Business Days prior to the first
anticipated filing date of a Registration Statement and at least five (5)
Business Days prior to the filing of any amendment or supplement to a
Registration Statement, the Company shall notify each Investor in writing of the
information, if any, the Company requires from each such Investor if such
Investor elects to have any of such Investor's Registrable Securities included
in such Registration Statement or, with respect to an amendment or a supplement,
if such Investor's Registrable Securities are included in such Registration
Statement (each an "INFORMATION REQUEST"). Provided that the Company shall have
complied with its obligations set forth in the preceding sentence, it shall be a
condition precedent to the obligations of the Company to complete the
registration pursuant to this Agreement with respect to the Registrable
Securities of a particular Investor that such Investor shall furnish to the
Company, in response to an Information Request, such information regarding
itself, the Registrable Securities held by it and the intended method of
disposition of the Registrable Securities held by it as shall be reasonably
required to effect the registration of such Registrable Securities and shall
execute such documents in connection with such registration as the Company may
reasonably request. If an Investor fails to provide the Company with the
information requested in the Information Request which the Company reasonably
requires within seven (7) Business Days (or five (5) Business Days in connection
with an amendment or supplement) after its receipt of the

                                       10

<PAGE>

Information Request, then the applicable Filing Deadline, Effectiveness Deadline
and the 15-day period referred to in Section 2(e) shall be extended solely with
respect to such Investor by one day for each day after such seventh (7th)
Business Day (or such fifth (5th) Business Day in the case of an amendment or
supplement) that the Investor fails to provide such information; provided,
however, that the failure of an Investor to timely provide such Information
pursuant to an Information Request shall not otherwise affect the Company's
obligations under this Agreement to the other Investors; provided, further,
however, that any Investor which fails to provide the Company with such
information within the applicable time period set forth above in response to an
Information Request prior to the filing of a Registration Statement or amendment
or supplement thereto shall bear the reasonable costs actually incurred by the
Company of any additional Registration Statement or amendment(s) or
supplement(s) thereto which the Company is required to file due solely to such
failure.

                  b. Each Investor, by such Investor's acceptance of the
Registrable Securities, agrees to cooperate with the Company as reasonably
requested by the Company in connection with the preparation and filing of any
Registration Statement hereunder, unless such Investor has notified the Company
in writing of such Investor's election to exclude all of such Investor's
Registrable Securities from such Registration Statement.

                  c. Each Investor agrees that, upon receipt of any notice from
the Company of the happening of any event of the kind described in Section 3(g)
or the first sentence of 3(f) or written notice from the company of a Grace
Period, such Investor will immediately discontinue disposition of Registrable
Securities pursuant to any Registration Statement(s) covering such Registrable
Securities until such Investor's receipt of the copies of the supplemented or
amended prospectus contemplated by Section 3(g) or the first sentence of 3(f) or
receipt of notice that no supplement or amendment is required or that the Grace
Period has ended. Notwithstanding anything to the contrary, the Company shall
cause its transfer agent to deliver unlegended shares of Common Stock to a
transferee of an Investor in accordance with the terms of the Securities
Purchase Agreement in connection with any sale of Registrable Securities with
respect to which an Investor has entered into a contract for sale prior to the
Investor's receipt of a notice from the Company of the happening of any event of
the kind described in Section 3(g) or the first sentence of 3(f) and for which
the Investor has not yet settled.

         5. EXPENSES OF REGISTRATION.

                  All reasonable expenses, other than underwriting discounts and
commissions and the fees and expenses of Legal Counsel or other legal and
professional advisors to any Investor, incurred in connection with
registrations, filings or qualifications pursuant to Sections 2 and 3,
including, without limitation, all registration, listing and qualifications
fees, printers and accounting fees, and fees and disbursements of counsel for
the Company shall be paid by the Company.

                                       11

         6. INDEMNIFICATION.

                  In the event any Registrable Securities are included in a
Registration Statement under this Agreement:

                  a. To the fullest extent permitted by law, the Company will,
and hereby does, indemnify, hold harmless and defend each Investor, the
directors, officers, partners, employees, agents, representatives of, and each
Person, if any, who controls any Investor within the meaning of the 1933 Act or
the 1934 Act (each, an "INDEMNIFIED PERSON"), against any losses, claims,
damages, liabilities, judgments, fines, penalties, charges, costs, reasonable
attorneys' fees, amounts paid in settlement or expenses, joint or several,
(collectively, "CLAIMS") incurred in investigating, preparing or defending any
action, claim, suit, inquiry, proceeding, investigation or appeal taken from the
foregoing by or before any court or governmental, administrative or other
regulatory agency, body or the SEC, whether pending or threatened, whether or
not an indemnified party is or may be a party thereto ("INDEMNIFIED DAMAGES"),
to which any of them may become subject insofar as such Claims (or actions or
proceedings, whether commenced or threatened, in respect thereof) arise out of
or are based upon: (i) any untrue statement or alleged untrue statement of a
material fact in a Registration Statement or any post-effective amendment
thereto or in any filing made in connection with the qualification of the
offering under the securities or other "blue sky" laws of any jurisdiction in
which Registrable Securities are offered ("BLUE SKY FILING"), or the omission or
alleged omission to state a material fact required to be stated therein or
necessary to make the statements therein not misleading, (ii) any untrue
statement or alleged untrue statement of a material fact contained in any
preliminary prospectus if used prior to the effective date of such Registration
Statement, or contained in the final prospectus (as amended or supplemented, if
the Company files any amendment thereof or supplement thereto with the SEC) or
the omission or alleged omission to state therein any material fact necessary to
make the statements made therein, in light of the circumstances under which the
statements therein were made, not misleading, (iii) any violation or alleged
violation by the Company of the 1933 Act, the 1934 Act, any other law,
including, without limitation, any state securities law, or any rule or
regulation thereunder relating to the offer or sale of the Registrable
Securities pursuant to a Registration Statement or (iv) any material violation
of this Agreement by the Company (the matters in the foregoing clauses (i)
through (iv) being, collectively, "VIOLATIONS"). Subject to Section 6(c), the
Company shall reimburse the Indemnified Persons, promptly as such expenses are
incurred and are due and payable, for any legal fees or other reasonable
expenses incurred by them in connection with investigating or defending any such
Claim. Notwithstanding anything to the contrary contained herein, the
indemnification agreement contained in this Section 6(a): (i) shall not apply to
a Claim by an Indemnified Person arising out of or based upon a Violation which
occurs in reliance upon and in conformity with information furnished in writing
to the Company by such Indemnified Person for such Indemnified Person expressly
for use in connection with the preparation of the Registration Statement or any
such amendment thereof or supplement thereto; (ii) with respect to any
preliminary prospectus, shall not inure to the benefit of any such person from
whom the person asserting any such Claim purchased the Registrable Securities
that are the subject thereof (or to the benefit of any person controlling such
person) if the untrue statement or omission of material fact contained in the
preliminary prospectus was corrected in the prospectus, as then amended or
supplemented, if such prospectus was timely made available by the Company
pursuant to Section 3(d), and the Indemnified Person was promptly advised in
writing not to use the incorrect prospectus

                                       12

<PAGE>

prior to the use giving rise to a violation and such Indemnified Person,
notwithstanding such advice, used it; (iii) shall not be available to the extent
such Claim is based on a failure of the Investor to deliver or to cause to be
delivered the prospectus made available by the Company, if such prospectus was
timely made available by the Company pursuant to Section 3(d); and (iv) shall
not apply to amounts paid in settlement of any Claim if such settlement is
effected without the prior written consent of the Company, which consent shall
not be unreasonably withheld. Such indemnity shall remain in full force and
effect regardless of any investigation made by or on behalf of the Indemnified
Person and shall survive the transfer of the Registrable Securities by the
Investors pursuant to Section 9.

                  b. In connection with any Registration Statement in which an
Investor is participating, each such Investor agrees to severally and not
jointly indemnify, hold harmless and defend, to the same extent and in the same
manner as is set forth in Section 6(a), the Company, each of its directors,
employees, agents and representatives, each of its officers who signs the
Registration Statement, each Person, if any, who controls the Company within the
meaning of the 1933 Act or the 1934 Act (each an "INDEMNIFIED PARTY"), against
any Claim or Indemnified Damages to which any of them may become subject, under
the 1933 Act, the 1934 Act or otherwise, insofar as such Claim or Indemnified
Damages arise out of or are based upon any Violation, in each case to the
extent, and only to the extent, that such Violation occurs in reliance upon and
in conformity with written information furnished to the Company by such Investor
expressly for use in connection with such Registration Statement; and, subject
to Section 6(c), such Investor will reimburse any legal or other expenses
reasonably incurred by an Indemnified Party in connection with investigating or
defending any such Claim; provided, however, that the indemnity agreement
contained in this Section 6(b) and the agreement with respect to contribution
contained in Section 7 shall not apply to amounts paid in settlement of any
Claim if such settlement is effected without the prior written consent of such
Investor, which consent shall not be unreasonably withheld; provided, further,
however, that the Investor shall be liable under this Section 6(b) for only that
amount of a Claim or Indemnified Damages as does not exceed the net proceeds to
such Investor as a result of the sale of Registrable Securities pursuant to such
Registration Statement. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of such Indemnified Party
and shall survive the transfer of the Registrable Securities by the Investors
pursuant to Section 9. Notwithstanding anything to the contrary contained
herein, the indemnification agreement contained in this Section 6(b) with
respect to any preliminary prospectus shall not inure to the benefit of any
Indemnified Party if the untrue statement or omission of material fact contained
in the preliminary prospectus was corrected on a timely basis in the prospectus,
as then amended or supplemented.

                  c. Promptly after receipt by an Indemnified Person or
Indemnified Party under this Section 6 of notice of the commencement of any
action or proceeding (including any governmental action or proceeding) involving
a Claim, such Indemnified Person or Indemnified Party shall, if a Claim in
respect thereof is to be made against any indemnifying party under this Section
6, deliver to the indemnifying party a written notice of the commencement
thereof, and the indemnifying party shall have the right to participate in, and,
to the extent the indemnifying party so desires, jointly with any other
indemnifying party similarly noticed, to assume control of the defense

                                       13

<PAGE>

thereof with counsel mutually satisfactory to the indemnifying party and the
Indemnified Person or the Indemnified Party, as the case may be; provided,
however, that an Indemnified Person or Indemnified Party shall have the right to
retain its own counsel with the fees and expenses of not more than one counsel
for such Indemnified Person or Indemnified Party to be paid by the indemnifying
party, if, in the reasonable opinion of counsel retained by the indemnifying
party, the representation by such counsel of the Indemnified Person or
Indemnified Party and the indemnifying party would be inappropriate due to
actual or potential differing interests between such Indemnified Person or
Indemnified Party and any other party represented by such counsel in such
proceeding. In the case of an Indemnified Person, legal counsel referred to in
the immediately preceding sentence shall be selected by the Investors holding a
majority in interest of the Registrable Securities included in the Registration
Statement to which the Claim relates. The Indemnified Party or Indemnified
Person shall cooperate fully with the indemnifying party in connection with any
negotiation or defense of any such action or Claim by the indemnifying party and
shall furnish to the indemnifying party all information reasonably available to
the Indemnified Party or Indemnified Person which relates to such action or
Claim. The indemnifying party shall keep the Indemnified Party or Indemnified
Person fully apprised at all times as to the status of the defense or any
settlement negotiations with respect thereto. No indemnifying party shall be
liable for any settlement of any action, claim or proceeding effected without
its prior written consent, provided, however, that the indemnifying party shall
not unreasonably withhold, delay or condition its consent. No indemnifying party
shall, without the prior written consent of the Indemnified Party or Indemnified
Person, consent to entry of any judgment or enter into any settlement or other
compromise which does not include as an unconditional term thereof the giving by
the claimant or plaintiff to such Indemnified Party or Indemnified Person of a
release from all liability in respect to such Claim or litigation. Following
indemnification as provided for hereunder, the indemnifying party shall be
subrogated to all rights of the Indemnified Party or Indemnified Person with
respect to all third parties, firms or corporations relating to the matter for
which indemnification has been made. The failure to deliver written notice to
the indemnifying party within a reasonable time of the commencement of any such
action shall not relieve such indemnifying party of any liability to the
Indemnified Person or Indemnified Party under this Section 6, except to the
extent that the indemnifying party is prejudiced in its ability to defend such
action.

                  d. The indemnification required by this Section 6 shall be
made by periodic payments of the amount thereof during the course of the
investigation or defense, as and when bills are received or Indemnified Damages
are incurred.

                  e. The indemnity agreements contained herein shall be in
addition to (i) any cause of action or similar right of the Indemnified Party or
Indemnified Person against the indemnifying party or others, and (ii) any
liabilities the indemnifying party may be subject to pursuant to the law.

                                       14

<PAGE>

         7. CONTRIBUTION.

                  To the extent any indemnification by an indemnifying party is
prohibited or limited by law, the indemnifying party agrees to make the maximum
contribution with respect to any amounts for which it would otherwise be liable
under Section 6 to the fullest extent permitted by law; provided, however, that:
(i) no Person involved in the sale of Registrable Securities which Person is
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the 1933 Act) in connection with such sale, shall be entitled to contribution
from any Person involved in such sale of Registrable Securities who was not
guilty of fraudulent misrepresentation; and (ii) contribution by any seller of
Registrable Securities shall be limited in amount to the net amount of proceeds
received by such seller from the sale of such Registrable Securities pursuant to
such Registration Statement.

         8. REPORTS UNDER THE 1934 ACT.

                  With a view to making available to the Investors the benefits
of Rule 144 promulgated under the 1933 Act or any other similar rule or
regulation of the SEC that may at any time permit the Investors to sell
securities of the Company to the public without registration ("RULE 144"), the
Company agrees to:

                  a. make and keep public information available, as those terms
are understood and defined in Rule 144;

                  b. file with the SEC in a timely manner all reports and other
documents required of the Company under the 1933 Act and the 1934 Act so long as
the Company remains subject to such requirements (it being understood that
nothing herein shall limit the Company's obligations under Section 4(c) of the
Securities Purchase Agreement) and the filing of such reports and other
documents is required for the applicable provisions of Rule 144; and

                  c. furnish to each Investor so long as such Investor owns
Registrable Securities, promptly upon request, (i) a written statement by the
Company that it has complied with the reporting requirements of Rule 144, the
1933 Act and the 1934 Act, (ii) a copy of the most recent annual or quarterly
report of the Company and such other reports and documents so filed by the
Company, and (iii) such other information as may be reasonably requested to
permit the investors to sell such securities pursuant to Rule 144 without
registration.

         9. ASSIGNMENT OF REGISTRATION RIGHTS.

                  The rights under this Agreement shall be automatically
assignable by the Investors to any transferee of all or any portion of
Registrable Securities if: (i) the Investor agrees in writing with the
transferee or assignee to assign such rights, and a copy of such agreement is
furnished to the Company within a reasonable time after such transfer or
assignment; (ii) the Company is, within a reasonable time after such transfer or
assignment, furnished with written notice of (a) the name and

                                       15

<PAGE>

address of such transferee or assignee, and (b) the securities with respect to
which such registration rights are being transferred or assigned; (iii)
immediately following such transfer or assignment the further disposition of
such securities by the transferee or assignee is restricted under the 1933 Act
and applicable state securities laws; (iv) at or before the time the Company
receives the written notice contemplated by clause (ii) of this sentence the
transferee or assignee agrees in writing with the Company to be bound by all of
the provisions contained herein; and (v) such transfer shall have been made in
accordance with the applicable requirements of the Securities Purchase
Agreement.

         10. AMENDMENT OF REGISTRATION RIGHTS.

                  Provisions of this Agreement may be amended and the observance
thereof may be waived (either generally or in a particular instance and either
retroactively or prospectively), only with the written consent of the Company
and Investors who then hold at least two-thirds (2/3) of the Registrable
Securities. Any amendment or waiver effected in accordance with this Section 10
shall be binding upon each Investor and the Company. No such amendment shall be
effective to the extent that it applies to less than all of the holders of the
Registrable Securities. No consideration shall be offered or paid to any Person
to amend or consent to a waiver or modification of any provision of any of this
Agreement unless the same consideration also is offered to all of the parties to
this Agreement.

         11. MISCELLANEOUS.

                  a. A Person is deemed to be a holder of Registrable Securities
whenever such Person owns or is deemed to own of record such Registrable
Securities. If the Company receives conflicting instructions, notices or
elections from two or more Persons with respect to the same Registrable
Securities, the Company shall act upon the basis of instructions, notice or
election received from the registered owner of such Registrable Securities.

                  b. Any notices, consents, waivers or other communications
required or permitted to be given under the terms of this Agreement must be in
writing and will be deemed to have been delivered: (i) upon receipt, when
delivered personally; (ii) upon receipt, when sent by facsimile (provided
confirmation of transmission is mechanically or electronically generated and
kept on file by the sending party); or (iii) one (1) Business Day after deposit
with a nationally recognized overnight delivery service, in each case properly
addressed to the party to receive the same. The addresses and facsimile numbers

                  d. All questions concerning the construction, validity,
enforcement and interpretation of this Agreement shall be governed by the
internal laws of the State of New York, without giving effect to any choice of
law or conflict of law provision or rule (whether of the State of New York or

hereunder or in connection herewith or with any transaction contemplated hereby
or discussed herein, and hereby irrevocably waives, and agrees not to assert in

process and consents to process being served in any such suit, action or
proceeding by mailing a copy thereof to such party at the address for such

herein shall be deemed to limit in any way any right to serve process in any
manner permitted by law. If any provision of this Agreement shall be invalid or
unenforceable in any jurisdiction, such invalidity or unenforceability shall not
affect the validity or enforceability of the remainder of this Agreement in that
jurisdiction or the validity or enforceability of any provision of this
Agreement in any other jurisdiction. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY
RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION
OF ANY DISPUTE HEREUNDER OR IN CONNECTION HEREWITH OR ARISING OUT OF THIS
AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY.

                  e. This Agreement, the Securities Purchase Agreement, the
Warrants and the Notes constitute the entire agreement among the parties hereto
with respect to the subject matter hereof and thereof. There are no
restrictions, promises, warranties or undertakings, other than those set forth
or referred to herein and therein. This Agreement, the Securities Purchase
Agreement, the Warrants and the Notes supersede all prior agreements and
understandings among the parties hereto with respect to the subject matter
hereof and thereof.

                  f. Subject to the requirements of Section 9, this Agreement
shall inure to the benefit of and be binding upon the permitted successors and

delivered to the other party hereto by facsimile transmission of a copy of this
Agreement bearing the signature of the party so delivering this Agreement.

performed, all such further acts and things, and shall execute and deliver all
such other agreements, certificates, instruments and documents, as the other
party may reasonably request in order to carry out the intent and accomplish the
purposes of this Agreement and the consummation of the transactions contemplated
hereby.

                  j. All consents and other determinations to be made by the
Investors pursuant to this Agreement shall be made, unless otherwise specified
in this Agreement, by Investors holding at least two-thirds (2/3) of the
Registrable Securities, determined as if all of the Notes and the Warrants then
outstanding have been converted into or exercised for Registrable Securities
without regard to any limitations on conversion of the Notes or the exercise of
the Warrants.

                  k. The language used in this Agreement will be deemed to be
the language chosen by the parties to express their mutual intent and no rules
of strict construction will be applied against any party.

                  RE: INTERVOICE-BRITE, INC.

Ladies and Gentlemen:

         We are counsel to InterVoice-Brite, Inc., a Texas corporation (the
"COMPANY"), and have represented the Company in connection with that certain
Securities Purchase Agreement (the "PURCHASE AGREEMENT") entered into by and
among the Company and the buyers named therein (collectively, the "HOLDERS")
pursuant to which the Company issued to the Holders convertible notes (the
"NOTES"), convertible into shares of the Company's common stock, no par value
per share (the "COMMON STOCK"), and warrants to purchase an aggregate of
_________ shares of Common Stock, subject to adjustment (the "WARRANTS").
Pursuant to the Purchase Agreement, the Company also has entered into a
Registration Rights Agreement with the Holders (the "REGISTRATION RIGHTS
AGREEMENT") pursuant to which the Company agreed, among other things, to
register the Registrable Securities (as defined in the Registration Rights
Agreement), including the shares of Common Stock issuable upon conversion of the
Notes and exercise of the Warrants, under the Securities Act of 1933, as amended
(the "1933 ACT"). In connection with the Company's obligations under the
Registration Rights Agreement, on ____________ ___, 200_, the Company filed a
Registration Statement on Form S-3 (File No. 333-_____________) (the
"REGISTRATION STATEMENT") with the Securities and Exchange Commission (the
"SEC") relating to the Registrable Securities which names each of the Holders as
a selling stockholder thereunder.

         In connection with the foregoing, we advise you that a member of the
SEC's staff has advised us by telephone that the SEC has entered an order
declaring the Registration Statement effective under the 1933 Act at [ENTER TIME
OF EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge,
after telephonic inquiry of a member of the SEC's staff, that any stop order
suspending its effectiveness has been issued or that any proceedings for that
purpose are pending before, or threatened by, the SEC and the Registrable
Securities are available for resale under the 1933 Act pursuant to the
Registration Statement.

[WITH SUCH ADDITIONAL ASSUMPTIONS AND OTHER INFORMATION AS COUNSEL MAY
REASONABLY DEEM ADVISABLE, PROVIDED IT IS CONSISTENT WITH SECTIONS 2(f) AND 2(g)
OF THE PURCHASE AGREEMENT.]

                                         Very truly yours,

                                         [ISSUER'S COUNSEL]

                                         By:
                                            ----------------------------------
