ITEM 5.  OTHER EVENTS.

     On July 24, 1998, the Company completed the first closing of a private
placement (the "Private Placement") of its Series D Convertible Preferred Stock
("Series D Preferred Stock") and related Common Stock Purchase Warrants ("Class
A Warrants") to Sovereign Partners L.P. and Dominion Capital Fund, Ltd. (the
"Class A Investors"), for an aggregate price of $1,500,000, and its Series E
Convertible Preferred Stock ("Series E Preferred Stock") and related Common
Stock Purchase Warrants ("Class B Warrants") to First Capital Group of Texas II,
L.P. (the "Class B Investor"), an investment firm managed by the Company's
Chairman of the Board, for a price of $750,000.  At such time, the Class A
Investors agreed to purchase at a second closing additional shares of Series D
Preferred Stock and Class A Warrants for an aggregate price of $1,000,000, and
the Class B Investor agreed to purchase at a second closing shares of Series F
Convertible Preferred Stock ("Series F Preferred Stock") and Class B Warrants
for a price of $750,000. The second closing is scheduled to occur on or before
January 31, 1999, and is subject the Company's satisfaction of certain
conditions, including, among others, the following: the average closing bid
price of the Company's Common Stock during the five trading days prior to the
closing is at least $1.50; in the case of the closing with respect to the Class
B Investor, the Company has a minimum of $750,000 in revenue for the quarter
ending September 30, 1998 or December 31, 1998; the shares of the Company's
Common Stock issuable upon conversion of the Preferred Stock ("Conversion
Shares") and upon exercise of the Warrants ("Warrant Shares") are registered for
resale pursuant to the Securities Act of 1933, as amended (the "Securities
Act"); the Company's shareholders approve the potential issuance of the
Conversion Shares and Warrant Shares in excess of certain limits imposed by
Nasdaq Marketplace Rules; the Company is in compliance with Nasdaq listing
requirements; and there is no material adverse change in the Company's financial
condition, business or prospects. The Company intends to use the proceeds from
the private placement primarily to promote its Be There! remote access system
product line and for working capital.

     Each of the Series D Preferred Stock, Series E Preferred Stock and Series F
Preferred Stock (the "Preferred Stock") has a stated value of $1,000 per share;
bears an 8% premium payable upon conversion or redemption or in liquidation (in
the case of conversion the Company may elect to pay such premium in Common
Stock); is non-voting except in limited circumstances; ranks senior to the
Common Stock in liquidation (and ranks equally with each other series of
Preferred Stock); and is redeemable at a premium at the option of the holder
under certain circumstances, including the occurrence of certain major corporate
transactions and the failure of the Company to register the Conversion Shares or
Warrant Shares within prescribed time periods.

     The Series D Preferred Stock is convertible into Common Stock of the
Company ("Common Stock") at the option of the holder beginning 90 days after the
issuance date (subject to acceleration in certain events), at a conversion price
equal to 80% of the trailing five-day average closing bid price of the Common
Stock on the conversion date, subject to a minimum conversion price equal to the
trailing 15-day average closing bid price of the Common Stock 90 days after the
issuance date and subject to a maximum conversion price equal to the lesser of
$3.00 or the trailing five-day average closing bid price of the Common Stock 90
days after the issuance date.  The Series E Preferred Stock is convertible into
Common Stock at the option of the holder beginning one year after the issuance
date (subject to acceleration in certain events), at a conversion price equal to
$1.00 (which represents a premium to the Common Stock closing price of $0.5938
on July 8, 1998 -- the 

                                       2

date the Company reached an agreement in principle with the Investors regarding
the terms of the Private Placement). The Series F Preferred Stock will be
convertible into Common Stock at the option of the holder beginning one year
after the second closing (subject to acceleration in certain events), at a
conversion price equal to the trailing five-day average closing bid price of the
Common Stock on the date of the second closing. Subject to certain limitations,
all Preferred Stock outstanding five years after the issuance date will convert
automatically into Common Stock at the applicable conversion price. In each
case, the number of shares of Common Stock issuable upon conversion of one share
of Preferred Stock is computed by dividing the share's stated value of $1,000 by
the applicable conversion price. Pursuant to Nasdaq Marketplace Rules, in the
absence of shareholder approval, the aggregate number of shares of Common Stock
that are issued at a discount from the market price pursuant to the Private
Placement may not equal or exceed 20% of the outstanding shares of Common Stock
on July 24, 1998 (i.e., 2,905,782 shares); any Preferred Stock which may not be
converted or Warrants which may not be exercised because of such limitation must
be redeemed at a premium by the Company in cash. The Company intends to seek
shareholder approval at its next annual meeting of the issuance of the Common
Stock pursuant to the Private Placement.

     If the Common Stock ceases to be listed on the Nasdaq National Market, the
Company must pay the holders of the Preferred Stock a cash penalty of 1% per
day, for up to 24 days, of the stated value of the Preferred Stock outstanding.
The holders may require the Company to redeem their shares of Preferred Stock if
the Company fails to pay such penalty.

     The Class A Warrants are exercisable 90 days after issuance (subject to
acceleration in certain events), at an exercise price equal to 120% of the
average of the three lowest closing bid prices during the 22 trading days prior
to issuance date, up to a maximum price of $.80 per share (the "Class A Warrant
Exercise Price"), to purchase that number of shares of Common Stock equal to 15%
of the stated value of the Series D Preferred Stock issued at each closing,
divided by the Class A Warrant Exercise Price.  Based on such formula, the
Company issued at the first closing Class A Warrants to purchase an aggregate of
339,623 shares of Common Stock at an exercise price of $0.6625 per share.  The
Class B Warrants are exercisable one year after issuance (subject to
acceleration in certain events), at an exercise price of $0.80 per share (the
"Class B Warrant Exercise Price"), to purchase that number of shares of Common
Stock equal to 15% of the stated value of the Series E Preferred Stock and
Series F Preferred Stock issued at each closing, divided by the Class B Warrant
Exercise Price.  Based on such formula, the Company issued at the first closing,
and is obligated to issue at the second closing, Class B Warrants to purchase
140,625 shares of Common Stock at an exercise price of $0.80 per share.  On July
8, 1998, the date the Company reached an agreement in principle with the
Investors regarding the terms of the Private Placement, the closing price of the
Common Stock was $0.5938.  The Class A Warrants and the Class B Warrants (the
"Warrants") each expire two years after the date of their issuance.

     The Company has agreed to file a registration statement under the
Securities Act covering the resale of the Conversion Shares and Warrant Shares.
The failure of such registration statement to be filed and declared effective
within certain prescribed time periods will result in cash penalties payable by
the Company to the holders of Preferred Stock.  The Class A Investors and the
Class B Investors (the "Investors") have agreed not to effect any short sales of
Common Stock during the one-year period following each closing.

                                       3

     A placement agent assisted the Company in arranging the Placement Placement
with the Class A Investors. As compensation for the investment by the Class A 
Investors in the first closing, the Company paid a cash fee equal to 6% of the 
gross proceeds received from the Class A Investors and issued Class A Warrants 
to purchase the same number of shares that may be purchased pursuant to the 
Class A Warrants issued to the Class A Investors. As compensation for the 
investment by the Class A Investors in the second closing, the Company agreed to
pay a cash fee equal to 3% of the gross proceeds received from the Class A 
Investors and to issue Class A Warrants to purchase one-half of the number of 
shares that may be purchased pursuant to the Class A Warrants to be issued to 
the Class A Investors.

     The offer and sale of the Preferred Stock and Warrants were, and, in 
connection with the second closing, will be, made in reliance upon Section 4(2) 
of the Securities Act, the non-public offering exemption from the registration 
requirements of the Securities Act.
 
THE SUMMARY OF THE PRIVATE PLACEMENT SET FORTH ABOVE IS QUALIFIED IN ITS
ENTIRETY BY REFERENCE TO THE PURCHASE AGREEMENT AND THE OTHER DOCUMENTS EXECUTED
BY THE COMPANY IN CONNECTION WITH THE PRIVATE PLACEMENT.  SUCH DOCUMENTS ARE
FILED AS EXHIBITS TO THIS FORM 8-K.

                                DATA RACE, INC.

                        Pursuant to Article 2.13 of the
                        Texas Business Corporation Act


     Data Race, Inc., a corporation organized and existing under the Texas
Business Corporation Act (the "COMPANY"), does hereby certify that the following
resolutions were adopted by the Board of Directors of the Company on July 20,
1998 pursuant to authority of the Board of Directors as required by Article 2.13
of the Texas Business Corporation Act.

          RESOLVED, that pursuant to the authority granted to and vested in the
     Board of Directors of this Company (the "BOARD OF DIRECTORS" or the
     "BOARD") in accordance with the provisions of its Articles of
     Incorporation, the Board of Directors hereby authorizes a series of the
     Company's previously authorized preferred Stock, no par value (the
     "PREFERRED STOCK"), and hereby states the designation and number of shares,
     and fixes the relative rights, preferences, privileges, powers and
     restrictions thereof as follows:

          Series D Convertible Preferred Stock:

          1.   Designation, Amount and Dividends. The designation of this
     series, which consists of 2,500 shares of Preferred Stock, is the Series D
     Convertible Preferred Stock (the "PREFERRED SHARES") and the stated value
     shall be One Thousand Dollars ($1,000.00) per share (the "STATED VALUE").
     The Preferred Shares shall not bear any dividends.

                                       1
<PAGE>
 
          2.   Holder's Conversion of Preferred Shares. A holder of Preferred
     Shares shall have the right, at such holder's option, to convert the
     Preferred Shares into shares of the Company's common stock, no par value
     per share (the "COMMON STOCK"), on the following terms and conditions:

               a.   Conversion Right. Subject to the provisions of Section 11
     below, at any time or times on or after the earliest of ninety (90) days
     following the Issuance Date (as defined below), the Mandatory Conversion
     Date (as defined below) or the occurrence of a Triggering Event (as defined
     below), any holder of Preferred Shares shall be entitled to convert any
     whole number of Preferred Shares into fully paid and nonassessable shares
     (rounded to the nearest whole share in accordance with Section 2(i) below)
     of Common Stock, at the Conversion Rate (as defined below); provided,
     however, that in no event shall any holder be entitled to convert Preferred
     Shares in excess of that number of Preferred Shares which, upon giving
     effect to such conversion, 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
     conversion. 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 conversion
     of the Preferred Shares with respect to which the determination of such
     proviso is being made, but shall exclude the number of shares of Common
     Stock which would be issuable upon (i) conversion of the remaining,
     nonconverted Preferred Shares beneficially owned by the holder and its
     affiliates and (ii) exercise or conversion of the unexercised or
     unconverted portion of any other securities of the Company (including,
     without limitation, any warrants) subject to a limitation on conversion or
     exercise analogous to the limitation contained herein beneficially owned by
     the holder and its affiliates. 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. Each holder may waive the foregoing limitation with
     respect to its conversions by written notice to the Company upon not less
     than 61 days prior notice (with such waiver taking effect only upon the
     expiration of such 61 day notice period), and such limitation shall not
     apply to conversions as of the Mandatory Conversion Date.

                    b.   Conversion Rate. Subject to the other provisions
     hereof, each of the Preferred Shares shall be convertible, at the option of
     the holder, into that number of shares of fully paid and nonassessable
     shares of Common Stock which is to be derived from dividing the Stated
     Value by the Conversion Price (the "Conversion Rate).

     For purposes of this Statement of Designation, the following terms shall
have the following meanings:

                    The "CLOSING BID PRICE" shall mean, for any security as of
any date, the last closing bid price for such security on the Nasdaq National
Market as reported by Bloomberg Financial Markets ("BLOOMBERG"), or, if the
Nasdaq National Market is not the principal trading market for such security,
the last closing bid price of such security on the principal securities exchange
or trading market where such security is listed or traded as reported by
Bloomberg, or if the foregoing do not apply, the last closing bid price of such
security in the over-the-counter market on the electronic 

                                       2
<PAGE>
 
bulletin board for such security as reported by Bloomberg, or, if no closing bid
price is reported for such security by Bloomberg, the last closing trade price
of such security as reported by Bloomberg, or, if no last closing trade price is
reported for such security by Bloomberg, the average of the bid prices of any
market makers for such security as reported in the "pink sheets" by the National
Quotation Bureau, Inc. If the Closing Bid Price cannot be calculated for such
security on such date on any of the foregoing bases, the Closing Bid Price of
such security on such date shall be the fair market value as mutually determined
by the Company and the holders of a majority of the outstanding Preferred
Shares. If the Company and the holders of Preferred Shares are unable to agree
upon the fair market value of the Common Stock, then such dispute shall be
resolved pursuant to Section 2(g)(iii) below with the term "Closing Bid Price"
being substituted for the term "Market Price". For purposes of calculating the
five and fifteen day trading periods with respect to the Fixed Conversion Price
and Floating Conversion Price as set forth below, all such determinations of the
Closing Bid Price shall be appropriately adjusted for any stock dividend, stock
split or other similar transaction during such periods.

                    "CONVERSION PRICE" means, as of any Conversion Date (as
defined below) or other date of determination, the lower of the Fixed Conversion
Price and the Floating Conversion Price, each in effect as of such date and
subject to adjustment as provided herein.

                    "FIXED CONVERSION PRICE" means the lesser of (i) Three
($3.00) Dollars, subject to adjustment as provided herein, and (ii) the average
Closing Bid Price of the Common Stock for the five (5) day trading period
immediately preceding the ninetieth (90th) day after the Issuance Date, subject
to adjustment thereafter as provided herein.

                    "FLOATING CONVERSION PRICE" means, as of any date of
determination, the greater of (i) eighty (80%) percent of the average Closing
Bid Price of the Common Stock during the five (5) day trading period immediately
preceding the Conversion Date, or (ii) the average Closing Bid Price of the
Common Stock over the fifteen (15) day trading period immediately preceding the
ninetieth (90th) day after the Issuance Date, subject to adjustment thereafter
in the same manner as the adjustments to the Fixed Conversion Price as provided
herein.

                    "ISSUANCE DATE" shall mean, with respect to each Preferred
Share, the date of issuance of the applicable Preferred Share.

                    "MARKET PRICE" shall mean, with respect to any security for
any date, the arithmetic average of the Closing Bid Price for such security on
each of the five consecutive trading days immediately preceding such date.

               c.   Premium. The Preferred Shares shall bear a non-compounding
premium at the rate of eight (8%) percent per annum. Accrual of such premium
shall commence on the Issuance Date. The premium on each Preferred Share shall
be payable by the Company upon conversion of the Preferred Share, at the
Company's option, in cash or, subject to the Exchange Cap as provided in Section
11, in shares of Common Stock (valued at the Market Price on the Conversion
Date) which have been previously registered by the Company for resale by the
holder of the Preferred Shares. The premium on each Preferred Share shall be
payable solely in cash by the Company upon redemption thereof or liquidation.

                                       3

               d.   Adjustment to Conversion Price -- Dilution and Other Events.
In order to prevent dilution of the rights granted under this Statement of
Designation, the Conversion Price will be subject to adjustment from time to
time as provided in this Section 2(d).

                    (i)  Adjustment of Fixed Conversion Price upon Issuance of
Common Stock. If and whenever on or after the date of issuance of the Preferred
Shares, the Company issues or sells, or is deemed to have issued or sold, any
shares of Common Stock (other than shares of Common Stock deemed to have been
issued by the Company in connection with Approved Issuances (as defined below))
for a consideration per share less than the Market Price in effect immediately
prior to such time (the "APPLICABLE PRICE"), then immediately after such issue
or sale, the Fixed Conversion Price shall be reduced to an amount equal to the
product of (x) the Fixed Conversion Price in effect immediately prior to such
issue or sale and (y) the quotient determined by dividing (1) the sum of (I) the
product of the Applicable Price and the number of shares of Common Stock Deemed
Outstanding (as defined below) immediately prior to such issue or sale, and (II)
the consideration, if any, received by the Company upon such issue or sale, by
(2) the product of (I) the Applicable Price and (II) the number of shares of
Common Stock Deemed Outstanding immediately after such issue or sale. For
purposes of determining the adjusted Fixed Conversion Price under this Section
2(d)(i), the following shall be applicable:

                         (A)  Issuance of Options. If the Company in any manner
     grants any rights or options to subscribe for or to purchase Common Stock
     (other than in connection with an Approved Issuance or upon conversion of
     the Preferred Shares) or any stock or other securities convertible into or
     exchangeable for Common Stock (such rights or options being herein called
     "OPTIONS" and such convertible or exchangeable stock or securities being
     herein called "CONVERTIBLE SECURITIES") and the price per share for which
     Common Stock is issuable upon the exercise of such Options or upon
     conversion or exchange of such Convertible Securities is less than the
     Applicable Price, then the total maximum number of shares of Common Stock
     issuable upon the exercise of such Options or upon conversion or exchange
     of the total maximum amount of such Convertible Securities issuable upon
     the exercise of such Options shall be deemed to be outstanding and to have
     been issued and sold by the Company for such price per share. For purposes
     of this Section 2(d)(i)(A), the "price per share for which Common Stock is
     issuable upon exercise of such Options or upon conversion or exchange of
     such Convertible Securities" is determined by dividing (I) the total
     amount, if any, received or receivable by the Company as consideration for
     the granting of such Options, plus the minimum aggregate amount of
     additional consideration payable to the Company upon the exercise of all
     such Options, plus in the case of such Options which relate to Convertible
     Securities, the minimum aggregate amount of additional consideration, if
     any, payable to the Company upon the issuance or sale of such Convertible
     Securities and the conversion or exchange thereof, by (II) the total
     maximum number of shares of Common Stock issuable upon exercise of such
     Options or upon the conversion or exchange of all such Convertible
     Securities issuable upon the exercise of such Options. No adjustment of the
     Fixed Conversion 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 or
     exchange of such Convertible Securities.

                                       4
<PAGE>
 
                         (B)  Issuance of Convertible Securities. If the Company
     in any manner issues or sells any Convertible Securities and the price per
     share for which Common Stock is issuable upon such conversion or exchange
     is less than the Applicable Price, then the maximum number of shares of
     Common Stock issuable upon conversion or exchange of such Convertible
     Securities shall be deemed to be outstanding and to have been issued and
     sold by the Company for such price per share. For the purposes of this
     Section 2(d)(i)(B), the "price per share for which Common Stock is issuable
     upon such conversion or exchange" is determined by dividing (I) the total
     amount received or receivable by the Company as consideration for the issue
     or sale of such Convertible Securities, plus the minimum aggregate amount
     of additional consideration, if any, payable to the Company upon the
     conversion or exchange thereof, by (II) the total maximum number of shares
     of Common Stock issuable upon the conversion or exchange of all such
     Convertible Securities. No adjustment of the Fixed Conversion Price shall
     be made upon the actual issue of such Common Stock upon conversion or
     exchange 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 Fixed Conversion Price had been or are to be made
     pursuant to other provisions of this Section 2(d)(i), no further adjustment
     of the Fixed Conversion Price shall be made by reason of such issue or
     sale.

                         (C)  Change in Option Price or Rate of Conversion. If
     the purchase price provided for in any Options, the additional
     consideration, if any, payable upon the issue, conversion or exchange of
     any Convertible Securities, or the rate at which any Convertible Securities
     are convertible into or exchangeable for Common Stock change at any time,
     the Fixed Conversion Price in effect at the time of such change shall be
     readjusted to the Fixed Conversion Price which would have been in effect at
     such time had such Options or Convertible Securities still outstanding
     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; provided that no adjustment shall be made if such
     adjustment would result in an increase of the Fixed Conversion Price then
     in effect.

                         (D)  Certain Definitions. For purposes of determining
     the adjusted Fixed Conversion Price under this Section 2(d)(i), the
     following terms have meanings set forth below:

                              (I)  "APPROVED ISSUANCES" shall mean (i) a loan
     from a commercial bank, (ii) any transaction involving the Company's
     issuances of securities (A) as consideration in a merger or consolidation
     or (B) as consideration for the acquisition of a business, product or
     license or other assets by the Company, (iii) the issuance of Common Stock
     in a firm commitment, underwritten public offering, (iv) the issuance of
     securities upon exercise or conversion of the Company's options, warrants
     or other convertible securities outstanding as of the date hereof, (v) the
     grant of additional options or warrants, or the issuance of additional
     securities, under any Company stock option plan, restricted stock plan,
     stock purchase plan or other plan or written compensation contract for the
     benefit of the Company's employees, consultants or directors, (vi) the
     issuance of securities pursuant to the Rights Agreement, dated September
     15, 1997, between the Company and ChaseMellon Shareholder Services, L.L.C.,
     as amended from time to time in accordance with its terms (the "Rights

                                       5
<PAGE>
 
     Agreement"), and (vii) the issuance of securities pursuant to the Purchase
     Agreement, or in connection with any of the transactions related thereto.

                              (II) "COMMON STOCK DEEMED OUTSTANDING" means, at
     any given time, the number of shares of Common Stock actually outstanding
     at such time, plus the number of shares of Common Stock deemed to be
     outstanding pursuant to Sections 2(d)(i)(A) and 2(d)(i)(B) hereof
     regardless of whether the Options or Convertible Securities are actually
     exercisable at such time, but excluding any shares of Common Stock issuable
     upon conversion of the Preferred Shares.

                         (E)  Treatment of Expired Options and Unexercised
     Convertible Securities. If, in any case, the total number of shares of
     Common Stock issuable upon the exercise of any Option or upon exercise,
     conversion or exchange of any Convertible Security is not, in fact, issued
     and the rights to exercise such Option or to exercise, convert or exchange
     such Convertible Securities shall have expired or terminated, the Fixed
     Conversion Price then in effect will be readjusted to the Fixed Conversion
     Price which would have been effect at the time of such expiration or
     termination had such Option or Convertible Securities, to the extent
     outstanding immediately prior to such expiration or termination (other than
     in respect of the actual number of shares of Common Stock issued upon
     exercise or conversion thereof), never been issued.

                         (F)  Effect on Fixed Conversion Price of Certain
     Events. For purposes of determining the adjusted Fixed Conversion Price
     under this Section 2(d)(i), the following shall be applicable:

                              (I)  Calculation of Consideration Received. 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 amount received by the Company therefor,
     before deduction of reasonable commissions, underwriting discounts or
     allowances or other reasonable expenses paid or incurred by the Company in
     connection with such issuance or sale. In case any Common Stock, Options or
     Convertible Securities are issued or sold for a consideration other than
     cash, the amount of the consideration other than cash received by the
     Company will be the fair value of such consideration, except where such
     consideration consists of securities, in which case the amount of
     consideration received by the Company will be the Market Price of such
     security on the date of receipt. In case 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 a
     majority of the Preferred Shares 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 forty-eight (48) hours of the tenth
     (10th) day following the Valuation Event by an independent, reputable
     appraiser 

                                       6
<PAGE>
 
     selected by the Company. The determination of such appraiser shall be
     deemed binding upon all parties absent manifest error.

                              (II) Integrated Transactions. 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
     for purposes of Section 2(d)(i)(A).

                              (III) Treasury Shares. The number of shares of
     Common Stock outstanding at any given time does not include shares owned or
     held by or for the account of the Company, and the disposition of any
     shares so owned or held will be considered an issue or sale of Common
     Stock.

                              (IV) 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 (assuming such
     issuance ultimately occurs).

                    (ii)  Adjustment of Fixed Conversion Price upon Subdivision
     or Combination of Common Stock. If the Company at any time subdivides (by
     any stock split, stock dividend, recapitalization or otherwise) one or more
     classes of its outstanding shares of Common Stock into a greater number of
     shares, the Fixed Conversion Price in effect immediately prior to such
     subdivision will be proportionately reduced. If the Company at any time
     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 Fixed Conversion Price in effect immediately prior to such
     combination will be proportionately increased.

                    (iii) Intentionally omitted.

                    (iv)  Reorganization, Reclassification, Consolidation,
     Merger or Sale. Any recapitalization, reorganization, reclassification,
     consolidation, merger, sale of all or substantially all of the Company's
     assets to another Person (as defined below) or other transaction which is
     effected in such a way that holders of Common Stock are entitled to receive
     (either directly or upon subsequent liquidation) stock, securities or
     assets with respect to or in exchange for Common Stock, other than a Major
     Transaction, is referred to herein as "ORGANIC CHANGE." Prior to the
     consummation of any Organic Change, the Company will appropriate provision
     (in form and substance reasonably satisfactory to the holders of a majority
     of the Preferred Shares then outstanding) to insure that each of the
     holders of the Preferred Shares will thereafter have the right to acquire
     and receive in lieu of or addition to (as the case may be) the shares of
     Common Stock otherwise acquirable and receivable upon the conversion of
     such holder's Preferred Shares, such shares of stock, securities or assets
     that 

                                       7
<PAGE>
 
     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 conversion of such holder's Preferred
     Shares had such Organic Change not taken place (without taking into account
     any limitations or restrictions on the timing or amount of conversions). In
     any such case, the Company will make appropriate provision (in form and
     substance reasonably satisfactory to the holders of a majority of the
     Preferred Shares then outstanding) with respect to such holders' rights and
     interests to insure that the provisions of this Section 2(d) and Section
     2(e) below will thereafter be applicable to the Preferred Shares
     (including, in the case of any such consolidation, merger or sale in which
     the successor entity or purchasing entity is other than the Company, an
     immediate adjustment of the Fixed Conversion Price to the value for the
     Common Stock reflected by the terms of such consolidation, merger or sale,
     if the value so reflected is less than the Fixed Conversion Price in effect
     immediately prior to such consolidation, merger or sale and an immediate
     revision to the Floating Conversion Price to reflect the price of the
     common stock of the surviving entity and the market in which such common
     stock is traded). The Company will not effect any such consolidation,
     merger or sale, other than a Major Transaction, unless prior to the
     consummation thereof, the successor entity (if other than the Company)
     resulting from consolidation or merger or the entity purchasing such assets
     assumes, by written instrument, the obligation to deliver to each holder of
     Preferred Shares such shares of stock, securities or assets as, in
     accordance with the foregoing provisions, such holder may be entitled to
     acquire. "PERSON" shall mean an individual, a limited liability company, a
     partnership, a joint venture, a corporation, a trust, an unincorporated
     organization and a government or any department or agency thereof.

                    (v)  Certain Events. If any event occurs of the type
     contemplated by the provisions of this Section 2(d) 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 Conversion Price so as to protect the rights
     of the holders of the Preferred Shares; provided that no such adjustment
     will increase the Conversion Price as otherwise determined pursuant to this
     Section 2(d).

                    (vi) Notices.

                         (A)  Immediately upon any adjustment of the Conversion
     Price, the Company will give written notice thereof to each holder of
     Preferred Shares, setting forth in reasonable detail and certifying the
     calculation of such adjustment.

                         (B)  The Company will give written notice to each
     holder of Preferred Shares at least twenty (20) days prior to the date on
     which the Company closes its books or takes a record (I) with respect to
     any dividend or distribution upon the Common Stock, (II) with respect to
     any pro rata subscription offer to holders of Common Stock or (III) for
     determining rights to vote with respect to any Organic Change, dissolution
     or liquidation and in no event shall such notice be provided to such holder
     prior to such information being made known to the public.

                                       8
<PAGE>
 
                         (C)  The Company will also give written notice to each
     holder of Preferred Shares at least twenty (20) days prior to the date on
     which any Organic Change, dissolution or liquidation will take place and in
     no event shall such notice be provided to such holder prior to such
     information being made known to the public.

               e.   Purchase Rights. In addition to any adjustments of the
Conversion Price pursuant to Section 2(d) above, if at any time after the
Issuance Date 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 holders of Preferred Shares 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 conversion of the Preferred
Shares (without taking into account any limitations or restrictions on the
timing or amount of conversions) 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.

               f.   [Intentionally omitted.]

               g.   Mechanics of Conversion. Subject to the Company's inability
to fully satisfy its obligations under a Conversion Notice (as defined below) as
provided for in Section 4 below:

                    (i)  Holder's Delivery Requirements. To convert Preferred
     Shares into full shares of Common Stock on any date (the "CONVERSION
     DATE"), the holder thereof shall (A) transmit by facsimile (or otherwise
     deliver), for receipt on or prior to 11:59 p.m., Eastern Time on such date,
     a copy of a fully executed notice of conversion in the form attached hereto
     as Exhibit I (the "CONVERSION NOTICE"), to the Company, and (B) surrender
     to a common carrier for delivery to the Company as soon as practicable
     following such date, the original certificates representing the Preferred
     Shares being converted (or an indemnification undertaking with respect to
     such shares in the case of their loss, theft or destruction) (the
     "PREFERRED STOCK CERTIFICATES") and the originally executed Conversion
     Notice.

                    (ii) Company's Response. Upon receipt by the Company of a
     facsimile copy of a Conversion Notice, the Company shall immediately send,
     via facsimile, a confirmation of receipt of such Conversion Notice to such
     holder. Upon receipt by the Company of the Preferred Stock Certificates to
     be converted pursuant to a Conversion Notice, together with the originally
     executed Conversion Notice, the Company or its designated transfer agent
     (the "TRANSFER AGENT") (as applicable) shall, on the next business day
     following the date of receipt of both (or the second business day following
     the date of receipt of both if received after 11:00 a.m. local time of the
     Company), (I) issue and surrender to a common carrier for overnight
     delivery to the address as specified in the Conversion 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, or
     (II) 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 The Depository Trust Company. If the number of Preferred Shares
     represented by the Preferred Stock Certificate(s) submitted for conversion
     is greater than the number of Preferred 

                                       9
<PAGE>
 
     Shares being converted, then the Company shall, as soon as practicable and
     in no event later than two business days after receipt of the Preferred
     Stock Certificate(s) and at its own expense, issue and deliver to the
     holder a new Preferred Stock Certificate representing the number of
     Preferred Shares not converted.

                    (iii) Dispute Resolution. In the case of a dispute as to the
     determination of the Market Price or the arithmetic calculation of the
     Conversion Rate, 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 as soon as possible, but in no event later than two (2) business
     days after receipt of such holder's Conversion Notice. If such holder and
     the Company are unable to agree upon the determination of the Market Price
     or arithmetic calculation of the Conversion Rate within one (1) business
     day of such disputed determination or arithmetic calculation being
     submitted to the holder, then the Company shall within one (1) business day
     submit via facsimile (A) the disputed determination of the Market Price to
     an independent, reputable investment bank or (B) the disputed arithmetic
     calculation of the Conversion Rate to its independent, outside accountant.
     The Company shall cause the investment bank 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 forty-eight (48) hours
     from the time it receives the disputed determinations or calculations. Such
     investment bank's or accountant's determination or calculation, as the case
     may be, shall be binding upon all parties absent manifest error. The period
     of time in which the Company is required to effect conversions or
     redemptions under this Statement of Designations shall be tolled with
     respect to the subject conversion or redemption pending resolution of any
     dispute by the Company made in good faith and in accordance with this
     Section 2(g)(iii).

                    (iv)  Record Holder. The person or persons entitled to
     receive the shares of Common Stock issuable upon a conversion of Preferred
     Shares shall be treated for all purposes as the record holder or holders of
     such shares of Common Stock on the Conversion Date.

                    (v)   Company's Failure to Timely Convert. If within three
     (3) business days of the Company's receipt of the Conversion Notice (the
     "SHARE DELIVERY PERIOD") the Company shall fail to issue a certificate to a
     holder for the number of shares of Common Stock to which such holder is
     entitled upon such holder's conversion of Preferred Shares or to issue a
     new Preferred Stock Certificate representing the number of Preferred Shares
     to which such holder is entitled pursuant to Section 2(g)(ii) (a
     "CONVERSION FAILURE"), in addition to all other available remedies which
     such holder may pursue hereunder and under the Purchase Agreement between
     the Company and the initial holders of the Preferred Shares (the " PURCHASE
     AGREEMENT") (including indemnification), the Company shall pay additional
     damages to such holder for each business day after such third (3rd)
     business day that such conversion is not timely effected in an amount equal
     to two (2%) percent per month of the product of (A) the number of shares of
     Common Stock not issued to the holder on a timely basis pursuant to Section
     2(g)(ii) and to which such holder is entitled, and (B) the Closing Bid
     Price of the Common Stock on the last possible date which the Company could
     have issued such Common Stock to such holder without violating Section
     2(g)(ii). If the Company fails to 

                                       10
<PAGE>
 
     pay the additional damages set forth in this Section 2(g)(v) within five
     business days of the date incurred, then the holder entitled to such
     payments shall have the right at any time, so long as the Company continues
     to fail to make such payments, to require the Company, upon written notice,
     to immediately issue, in lieu of the cash additional damages set forth in
     this Section 2(g)(v), the number of shares of Common Stock equal to the
     quotient of (X) the aggregate amount of the additional damages payments
     described above divided by (Y) the Market Price in effect on such
     Conversion Date as is specified by the holder in writing to the Company.
     Payment of the additional damages shall not relieve the Company of its
     obligation to send the shares of Common Stock to the holder upon
     conversion.

               h.   Mandatory Conversion. Subject to Section 11, if any
     Preferred Shares remain outstanding on the Mandatory Conversion Date (as
     defined below), then all such Preferred Shares shall be converted as of
     such date in accordance with this Section 2 as if the holders of such
     Preferred Shares had given the Conversion Notice on the Mandatory
     Conversion Date; provided, however, that if a Triggering Event has occurred
     and is continuing on the Mandatory Conversion Date, then the Company shall,
     within five business days following the Mandatory Conversion Date (unless
     otherwise notified in writing by the holder of its request to have the
     Preferred Shares converted into Common Stock), pay to each holder of
     Preferred Shares then outstanding, in immediately available funds, an
     amount equal to the Triggering Event Redemption Price as of the Mandatory
     Conversion Date. All holders of Preferred Shares shall thereupon surrender
     all Preferred Stock Certificates, duly endorsed for cancellation, to the
     Company or the Transfer Agent, provided that the Company has complied with
     its obligations under this Section 2(h). Notwithstanding the foregoing,
     except in the case of a Major Transaction, if the Common Stock is not
     designated for quotation on the Nasdaq National Market or listed on The New
     York Stock Exchange, Inc. or The American Stock Exchange, Inc. but such
     events do not constitute a Triggering Event, then the Mandatory Conversion
     Date shall be extended until the Common Stock is so designated or listed.
     "MANDATORY CONVERSION DATE" means the date which is the earlier of five
     years after the applicable Issuance Date, subject to extension as described
     in the immediately preceding sentence, or immediately prior to a Major
     Transaction.

               i.   Fractional Shares. The Company shall not issue any fraction
     of a share of Common Stock upon any conversion. All shares of Common Stock
     (including fractions thereof) issuable upon conversion of more than one
     Preferred Share by a holder thereof shall be aggregated for purposes of
     determining whether the conversion would result in the issuance of a
     fraction of a share of Common Stock. If, after the aforementioned
     aggregation, the issuance would result in the issuance of a fraction of a
     share of Common Stock, the Company shall round such fraction of a share of
     Common Stock up or down to the nearest whole share.

               j.   Taxes. The Company shall pay any and all taxes which may be
     imposed upon it with respect to the issuance and delivery of Common Stock
     upon the conversion of the Preferred Shares.

          3.   Redemption at Option of Holders.

               a.   Redemption Option Upon Major Transaction. In addition to all
     other rights of the holders of Preferred Shares contained herein,
     simultaneous with the occurrence of a Major Transaction (as defined below),
     each holder of Preferred Shares shall have the right, at such holder's
     option, to require the Company to redeem all or a portion of such holder's
     Preferred Shares at a price per Preferred Share equal to 120% of the
     Liquidation Preference (as defined in Section 8 below) ("MAJOR TRANSACTION
     REDEMPTION PRICE").

               b.   Redemption Option Upon Triggering Event. In addition to all
     other rights of the holders of Preferred Shares contained herein, after a
     Triggering Event (as defined below), each holder of Preferred Shares shall
     have the right, at such holder's option, to require the Company to redeem
     all or a portion of such holder's Preferred Shares at a price per Preferred
     Share equal to 120% of the Liquidation Preference ("TRIGGERING EVENT
     REDEMPTION PRICE" and, collectively with "MAJOR TRANSACTION REDEMPTION
     PRICE," the "REDEMPTION PRICE").

               c.   "Major Transaction". A "MAJOR TRANSACTION" shall be deemed
     to have occurred at such time as any of the following events:

                    (i)   the consolidation, merger or other business
     combination of the Company with or into another Person which requires or
     receives the consent or recommendation of the Company's Board of Directors
     (excluding a consolidation, merger or other business combination in which
     holders of the Company's voting power immediately prior to the transaction
     continue after the transaction to hold, directly or indirectly, the voting
     power of the surviving entity or entities necessary to elect a majority of
     the members of the board of directors (or their equivalent if other than a
     corporation) of such entity or entities and excluding a short-form merger
     effected without the consent or recommendation of the Company's Board of
     Directors) (an "EXEMPT MAJOR TRANSACTION").

                    (ii)  the sale or transfer of all or substantially all of
     the Company's assets or rights to the "Be There!" business or product line
     other than in connection with a disposition to a subsidiary of the Company;
     or

                    (iii) consummation of a purchase, tender or exchange offer
     made to the holders of more than 50% of the outstanding shares of Common
     Stock which requires or receives the consent or recommendation of the
     Company's Board of Directors.

               d.   "Triggering Event". A "TRIGGERING EVENT" shall be deemed to
     have occurred at such time as any of the following events (other than in
     connection with a Major Transaction):

                    (i)   the failure of the Registration Statement to be
     declared effective by the SEC on or prior to the date that is 150 days
     after the Demand;

                                       12
<PAGE>
 
                    (ii)  while the Registration Statement is required to be
     maintained effective pursuant to the terms of the Registration Rights
     Agreement, the effectiveness of the Registration Statement lapses for any
     reason (including, without limitation, the issuance of a stop order) or is
     unavailable to the holder of the Preferred Shares for sale of all of the
     Registrable Securities (as defined in the Registration Rights Agreement) in
     accordance with the terms of the Registration Rights Agreement, and such
     lapse or unavailability continues for a period of thirty (30) consecutive
     trading days, provided that the cause of such lapse or unavailability is
     not due to factors solely within the control of such holder of Preferred
     Shares;

                    (iii) the Company undertakes any voluntary action to
     terminate the quotation or listing of the Common Stock on the Nasdaq
     National Market, The New York Stock Exchange, Inc. or The American Stock
     Exchange, Inc., unless such action is taken in connection with the
     continued quotation or listing of the Common Stock on another of the Nasdaq
     National Market, The New York Stock Exchange, Inc. or The American Stock
     Exchange, Inc.;

                    (iv)  the Company's failure to deliver shares of Common
     Stock within 15 days of its receipt of a Conversion Notice (together with
     the Preferred Stock Certificate) or the Company's notice to any holder of
     Preferred Shares, including by way of public announcement, at any time, of
     its intention not to comply with proper requests for conversion of any
     Preferred Shares into shares of Common Stock, other than due to any of the
     reasons set forth in Section 4(a) below; or

                    (v)   if the Company pursuant to or within the meaning of
     Title 11, U.S. Code, or any similar federal or state law for the relief of
     debtors ("BANKRUPTCY LAW"), (I) commences a voluntary case, (II) consents
     to the entry of an order for relief against it in any involuntary case,
     (III) consents to the appointment of a receiver, trustee, assignee,
     liquidator or similar official under any Bankruptcy Law (a "CUSTODIAN") of
     it or for all or substantially all of its property, (IV) makes a general
     assignment for the benefit of its creditors, or (V) admits in writing that
     it is generally unable to pay its debts as the same become due.

               e.   Mechanics of Redemption at Option of Buyer Upon Major
     Transaction. No sooner than 15 days nor later than 10 days prior to the
     consummation of a Major Transaction, but not prior to the public
     announcement of such Major Transaction, the Company shall deliver written
     notice thereof via facsimile and overnight courier ("NOTICE OF MAJOR
     TRANSACTION") to each holder of Preferred Shares. At any time after receipt
     of a Notice of Major Transaction (or, in the event a Notice of Major
     Transaction is not delivered at least 10 days prior to a Major Transaction,
     at any time within 10 days prior to a Major Transaction), any holder of
     Preferred Shares then outstanding may require the Company to redeem,
     effective immediately prior to the consummation of such Major Transaction,
     all of the holder's Preferred Shares then outstanding by delivering written
     notice thereof via facsimile and overnight courier ("NOTICE OF REDEMPTION
     AT OPTION OF BUYER UPON MAJOR TRANSACTION") to the Company, which Notice of
     Redemption at Option of Buyer Upon Major Transaction shall indicate (i) the
     number of Preferred Shares that such holder is electing to redeem and (ii)
     the applicable Major Transaction Redemption Price, as calculated pursuant
     to Section 3(a) above. Preferred Shares 

                                       13
<PAGE>
 
     which are not required to be redeemed pursuant to this paragraph are
     subject to mandatory conversion as provided herein.

               f.   Mechanics of Redemption at Option of Buyer Upon Triggering
     Event. Within one (1) day after the occurrence of a Triggering Event, the
     Company shall deliver written notice thereof via facsimile and overnight
     courier ("NOTICE OF TRIGGERING EVENT") to each holder of Preferred Shares.
     At any time after the earlier of a holder's receipt of a Notice of
     Triggering Event and such holder becoming aware of a Triggering Event, any
     holder of Preferred Shares then outstanding may require the Company to
     redeem all of the Preferred Shares by delivering written notice thereof via
     facsimile and overnight courier ("NOTICE OF REDEMPTION AT OPTION OF BUYER
     UPON TRIGGERING EVENT") to the Company, which Notice of Redemption at
     Option of Buyer Upon Triggering Event shall indicate (i) the number of
     Preferred Shares that such holder is electing to redeem and (ii) the
     applicable Triggering Event Redemption Price, as calculated pursuant to
     Section 3(b) above.

               g.   Payment of Redemption Price. Upon the Company's receipt of a
     Notice(s) of Redemption at Option of Buyer Upon Triggering Event or a
     Notice(s) of Redemption at Option of Buyer Upon Major Transaction from any
     holder of Preferred Shares or Pari Passu Shares (as defined in Section 8),
     the Company shall immediately notify each holder of Preferred Shares and
     Pari Passu Shares by facsimile of the Company's receipt of such Notice(s)
     of Redemption at Option of Buyer Upon Triggering Event or Notice(s) of
     Redemption at Option of Buyer Upon Major Transaction and each holder which
     has sent such a notice shall promptly submit to the Company or its Transfer
     Agent such holder's Preferred Stock Certificates which such holder has
     elected to have redeemed. The Company shall deliver the applicable
     Triggering Event Redemption Price, in the case of a redemption pursuant to
     Section 3(f), to such holder within five business days after the Company's
     receipt of a Notice of Redemption at Option of Buyer Upon Triggering Event
     and, in the case of a redemption pursuant to Section 3(e), the Company
     shall deliver the applicable Major Transaction Redemption Price immediately
     prior to the consummation of the Major Transaction; provided that a
     holder's Preferred Stock Certificates shall have been so delivered to the
     Company; provided further that if the Company is unable to redeem all of
     the Preferred Shares and Pari Passu Shares to be redeemed (because of
     insufficient funds to lawfully effect such redemption), the Company shall
     redeem an amount from each holder of Preferred Shares and Pari Passu Shares
     being redeemed equal to such holder's pro-rata amount (based on the
     relative redemption amounts of all holders of Preferred Shares and Pari
     Passu Shares) of all Preferred Shares and Pari Passu Shares being redeemed.
     If the Company shall fail to redeem all of the Preferred Shares submitted
     for redemption (other than pursuant to a dispute as to the arithmetic
     calculation of the Redemption Price), in addition to any remedy such holder
     of Preferred Shares may have under this Statement of Designations and the
     Purchase Agreement, the applicable Redemption Price payable in respect of
     such unredeemed Preferred Shares shall bear interest at the rate of 2.0%
     per month (prorated for partial months) until paid in full. Until the
     Company pays such unpaid applicable Redemption Price in full to a holder of
     Preferred Shares submitted for redemption, such holder shall have the
     option (the "VOID OPTIONAL REDEMPTION OPTION") to, in lieu of redemption,
     require the Company to promptly return to such holder(s) all of the
     Preferred Shares that were submitted for redemption by such holder(s) under
     this Section 3 and for which the applicable Redemption Price has not been
     paid, by sending written notice thereof 

                                       14
<PAGE>
 
     to the Company via facsimile (the "VOID OPTIONAL REDEMPTION NOTICE"). Upon
     the Company's receipt of such Void Optional Redemption Notice(s) and prior
     to payment of the full applicable Redemption Price to such holder, (i) the
     Notice(s) of Redemption at Option of Buyer Upon Triggering Event or the
     Notice(s) of Redemption at Option of Buyer Upon Major Transaction, as the
     case may be, shall be null and void with respect to those Preferred Shares
     submitted for redemption and for which the applicable Redemption Price has
     not been paid, and (ii) the Company shall immediately return any Preferred
     Shares submitted to the Company by each holder for redemption under this
     Section 3(g) and for which the applicable Redemption Price has not been
     paid. Notwithstanding the foregoing, in the event of a dispute as to the
     determination of the Closing Bid Price or the arithmetic calculation of the
     Redemption Price, such dispute shall be resolved pursuant to Section
     2(g)(iii) above with the term "Closing Bid Price" being substituted for the
     term "Average Market Price" and the term "Redemption Price" being
     substituted for the term "Conversion Rate". A holder's delivery of a Void
     Optional Redemption Notice and exercise of its rights following such notice
     shall not affect the Company's obligations to make any payments which have
     accrued prior to the date of such notice. Payments provided for in this
     Section 3 shall have priority to payments to other stockholders, other than
     any required payments with respect to shares of the Company's Series A
     Convertible Preferred Stock which were outstanding on the Issuance Date, in
     connection with a Major Transaction.

          4.   Inability to Fully Convert.

               a.   Holder's Option if Company Cannot Fully Convert. If, upon
     the Company's receipt of a Conversion Notice or on the Mandatory Conversion
     Date, the Company can not issue shares of Common Stock registered for
     resale under the Registration Statement for any reason, including, without
     limitation, because the Company (x) does not have a sufficient number of
     shares of Common Stock authorized and available, (y) is otherwise
     prohibited by applicable law or by the rules or regulations of any stock
     exchange, interdealer quotation system or other self-regulatory
     organization with jurisdiction over the Company or its Securities,
     including without limitation the Exchange Cap, from issuing all of the
     Common Stock which is to be issued to a holder of Preferred Shares pursuant
     to a Conversion Notice or (z) fails to have a sufficient number of shares
     of Common Stock registered for resale under the Registration Statement,
     then the Company shall issue as many shares of Common Stock as it is able
     to issue in accordance with such holder's Conversion Notice and pursuant to
     Section 2(g) above and, with respect to the unconverted Preferred Shares,
     the holder, solely at such holder's option, can elect to:

                    (i)   require the Company to redeem from such holder those
     Preferred Shares for which the Company is unable to issue Common Stock in
     accordance with such holder's Conversion Notice ("MANDATORY REDEMPTION") at
     a price per Preferred Share (the "MANDATORY REDEMPTION PRICE") equal to the
     Triggering Event Redemption Price as of such Conversion Date;

                    (ii)  if the Company's inability to fully convert Preferred
     Shares is pursuant to Section 4(a)(z) above, require the Company to issue
     restricted shares of Common Stock in accordance with such holder's
     Conversion Notice and pursuant to Section 2(g) above;

                                       15
<PAGE>
 
                    (iii) void its Conversion Notice and retain or have
     returned, as the case may be, the nonconverted Preferred Shares that were
     to be converted pursuant to such holder's Conversion Notice (provided that
     a holder's voiding its Conversion Notice shall not effect the Company's
     obligations to make any payments which have accrued prior to the date of
     such notice); or

                    (iv)  if the Company's inability to fully convert Preferred
     Shares is pursuant to the Exchange Cap described in Section 4(a)(y) above,
     and the issuance of additional Conversion Shares at a Conversion Price
     equal to the Market Price would not violate the rules or regulations of The
     Nasdaq Stock Market, Inc., then, subject to Section 11, require the Company
     to issue shares of Common Stock in accordance with such holder's Conversion
     Notice and pursuant to Section 2(g) above at a Conversion Price equal to
     the Market Price of the Common Stock on the date of such holder's Notice in
     Response to Inability to Convert (as defined below).

               b.   Mechanics of Fulfilling Holder's Election. The Company shall
     immediately send via facsimile to a holder of Preferred Shares, upon
     receipt of a facsimile copy of a Conversion Notice from such holder which
     cannot be fully satisfied as described in Section 4(a) above, a notice of
     the Company's inability to fully satisfy such holder's Conversion Notice
     (the "INABILITY TO FULLY CONVERT NOTICE"). Such Inability to Fully Convert
     Notice shall indicate (i) the reason why the Company is unable to fully
     satisfy such holder's Conversion Notice, (ii) the number of Preferred
     Shares which cannot be converted and (iii) the applicable Mandatory
     Redemption Price. Such holder shall notify the Company of its election
     pursuant to Section 4(a) above by delivering written notice via facsimile
     to the Company ("NOTICE IN RESPONSE TO INABILITY TO CONVERT").

               c.   Payment of Redemption Price. If such holder shall elect to
     have its shares redeemed pursuant to Section 4(a)(i) above, the Company
     shall pay the Mandatory Redemption Price in cash to such holder within
     thirty (30) days of the Company's receipt of the holder's Notice in
     Response to Inability to Convert, provided that prior to the Company's
     receipt of the holder's Notice in Response to Inability to Convert the
     Company has not delivered a notice to such holder stating, to the
     satisfaction of the holder, that the event or condition resulting in the
     Mandatory Redemption has been cured and all Conversion Shares issuable to
     such holder can and will be delivered to the holder in accordance with the
     terms of Section 2(g). If the Company shall fail to pay the applicable
     Mandatory Redemption Price to such holder on a timely basis as described in
     this Section 4(c) (other than pursuant to a dispute as to the determination
     of the arithmetic calculation of the Redemption Price), in addition to any
     remedy such holder of Preferred Shares may have under this Statement of
     Designations and the Securities Purchase Agreement, such unpaid amount
     shall bear interest at the rate of 2.0% per month (prorated for partial
     months) until paid in full. Until the full Mandatory Redemption Price is
     paid in full to such holder, such holder may void the Mandatory Redemption
     with respect to those Preferred Shares for which the full Mandatory
     Redemption Price has not been paid and receive back such Preferred Shares.
     Notwithstanding the foregoing, if the Company fails to pay the applicable
     Mandatory Redemption Price within such thirty (30) days time period due to
     a dispute as to the determination of the arithmetic 

                                       16
<PAGE>
 
     calculation of the Redemption Rate, such dispute shall be resolved pursuant
     to Section 2(g)(iii) above with the term "Redemption Price" being
     substituted for the term "Conversion Rate".

               d.   Pro-rata Conversion and Redemption. In the event the Company
     receives a Conversion Notice from more than one holder of Preferred Shares
     or Pari Passu Shares on the same day and the Company can convert and redeem
     some, but not all, of the Preferred Shares or Pari Passu Shares pursuant to
     this Section 4, the Company shall convert and redeem from each holder of
     Preferred Shares or Pari Passu Shares electing to have Preferred Shares or
     Pari Passu Shares converted and redeemed at such time an amount equal to
     such holder's pro-rata amount (based on the relative redemption amounts of
     all holders of Preferred Shares and Pari Passu shares) of all Preferred
     Shares and Pari Passu Shares being converted and redeemed at such time.

               e.   Involuntary Delisting. In the event the Common Stock at any
     time is not designated for quotation on the Nasdaq National Market or
     listed on The New York Stock Exchange, Inc. or The American Stock Exchange,
     Inc. but such events do not constitute a Triggering Event and are not in
     connection with a Major Transaction, then in addition to any other remedies
     the holders of Preferred Shares may have at law or in equity, the Company
     shall pay to each holder of Preferred Shares an amount in cash per
     Preferred Share on each day that the Common Stock is not so designated or
     listed equal to the product of the Liquidation Preference multiplied by
     1.0%, provided that the Company shall not be required to make such payments
     for more than 24 consecutive days. The Company's failure to pay such
     amounts on each day they are due shall constitute a Triggering Event for
     purposes of Section 3.

          5.   Reissuance of Certificates. In the event of a conversion or
     redemption pursuant to this Statement of Designations of less than all of
     the Preferred Shares represented by a particular Preferred Stock
     Certificate, the Company shall promptly cause to be issued and delivered to
     the holder of such Preferred Shares a preferred stock certificate
     representing the remaining Preferred Shares which have not been so
     converted or redeemed.

          6.   Reservation of Shares. Subject to the Exchange Cap in Section 11,
     the Company shall, so long as any of the Preferred Shares are outstanding,
     reserve and keep available out of its authorized and unissued Common Stock,
     solely for the purpose of effecting the conversion of the Preferred Shares,
     such number of shares of Common Stock as shall from time to time be
     sufficient to effect the conversion of all of the Preferred Shares then
     outstanding; provided that the number of shares of Common Stock so reserved
     shall at no time be less than 200% of the number of shares of Common Stock
     for which the Preferred Shares are at any time convertible (subject to the
     Exchange Cap if lower). The initial number of shares of Common Stock
     reserved for conversions of the Preferred Shares and each increase in the
     number of shares so reserved shall be allocated pro rata among the holders
     of the Preferred Shares based on the number of Preferred Shares held by
     each holder at the time of issuance of the Preferred Shares or increase in
     the number of reserved shares, as the case may be. In the event a holder
     shall sell or otherwise transfer any of such holder's Preferred Shares,
     each transferee shall be allocated a pro rata portion of the number of
     reserved shares of Common Stock reserved for such transferor. Any shares of
     Common Stock reserved and which remain allocated to any person or entity
     which does not hold any Preferred Shares shall be allocated to 

                                       17
<PAGE>
 
     the remaining holders of Preferred Shares, pro rata based on the number of
     Preferred Shares then held by such holder.

          7.   Voting Rights. Holders of Preferred Shares shall have no voting
     rights (including with respect to a Major Transaction), except as expressly
     required by law, including but not limited to the Texas Business
     Corporation Act, and as expressly provided in this Statement of
     Designations.

          8.   Liquidation, Dissolution, Winding-Up. In the event of any
     voluntary or involuntary liquidation, dissolution or winding up of the
     Company, the holders of the Preferred Shares shall be entitled to receive
     in cash out of the assets of the Company, whether from capital or from
     earnings available for distribution to its stockholders (the "PREFERRED
     FUNDS"), after all required payments with respect to shares of the
     Company's Series A Convertible Preferred Stock which were outstanding on
     the Issuance Date, but before any amount shall be paid to the holders of
     any of the capital stock of the Company of any class junior in rank to the
     Preferred Shares in respect of the preferences as to the distributions and
     payments on the liquidation, dissolution and winding up of the Company, an
     amount per Preferred Share equal to the Stated Value plus all accrued and
     unpaid premium thereon (such sum being referred to as the "LIQUIDATION
     PREFERENCE"); provided that, if the Preferred Funds are insufficient to pay
     the full amount due to the holders of Preferred Shares and holders of the
     Company's Series E Convertible Preferred Stock and Series F Convertible
     Preferred Stock (the "Pari Passu Shares"), which are of equal rank with the
     Preferred Shares as to payments of Preferred Funds (and redemption
     amounts), then each holder of Preferred Shares and Pari Passu Shares shall
     receive a percentage of the Preferred Funds equal to the full amount of
     Preferred Funds payable to such holder as a liquidation preference, in
     accordance with their respective Statement of Designations, Preferences and
     Rights, as a percentage of the full amount of Preferred Funds payable to
     all holders of Preferred Shares and Pari Passu Shares. The purchase or
     redemption by the Company of stock of any class, in any manner permitted by
     law, shall not, for the purposes hereof, be regarded as a liquidation,
     dissolution or winding up of the Company. Neither the consolidation or
     merger of the Company with or into any other Person, nor the sale or
     transfer by the Company of less than substantially all of its assets,
     shall, for the purposes hereof, be deemed to be a liquidation, dissolution
     or winding up of the Company. No holder of Preferred Shares shall be
     entitled to receive any amounts with respect thereto upon any liquidation,
     dissolution or winding up of the Company other than the amounts provided
     for herein; provided that a holder of Preferred Shares shall be entitled to
     all amounts previously accrued with respect to amounts owed hereunder.

          9.   Preferred Rank; Participation. (i) All shares of Common Stock
     shall be of junior rank to all Preferred Shares and Pari Passu Shares in
     respect to the preferences as to distributions and payments upon the
     liquidation, dissolution and winding up of the Company. The rights of the
     shares of Common Stock shall be subject to the preferences and relative
     rights of the Preferred Shares and Pari Passu Shares. Without the prior
     express written consent of the holders of not less than three-fourths (3/4)
     of the then outstanding Preferred Shares and Pari Passu Shares, the Company
     shall not hereafter authorize or issue additional or other capital stock
     that is of senior or equal rank to the Preferred Shares and Pari Passu
     Shares in respect of the preferences as to distributions and payments upon
     the liquidation, dissolution and winding 

                                       18
<PAGE>
 
     up of the Company. Without the prior express written consent of the holders
     of not less than three-fourths (3/4) of the then outstanding Preferred
     Shares and Pari Passu Shares, the Company shall not hereafter authorize or
     make any amendment to the Company's Articles of Incorporation or bylaws, or
     file any resolution of the board of directors of the Company with the Texas
     Secretary of State containing any provisions, which would adversely affect
     or otherwise impair the rights or relative priority of the holders of the
     Preferred Shares and Pari Passu Shares relative to the holders of the
     Common Stock or the holders of any other class of capital stock; provided
     that the foregoing shall not affect the Company's ability to effect a Major
     Transaction. In the event of the merger or consolidation of the Company
     with or into another corporation (other than a Major Transaction), the
     Preferred Shares and Pari Passu Shares shall maintain their relative
     powers, designations and preferences provided for herein and no merger
     shall result inconsistent therewith.

          (ii) Subject to the rights of the holders, if any, of the Parri Passu
     Shares, the holders of the Preferred Shares shall, as holders of Preferred
     Stock, be entitled to such dividends paid and distributions made to the
     holders of Common Stock to the same extent as if such holders of Preferred
     Shares had converted the Preferred Shares into Common Stock (without regard
     to any limitations on conversion herein or elsewhere) and had held such
     shares of Common Stock on the record date for such dividends and
     distributions. Payments under the preceding sentence shall be made
     concurrently with the dividend or distribution to the holders of Common
     Stock; provided that the holders of the Preferred Shares shall be entitled
     to such dividends and distributions only to the extent that they exceed an
     amount per Preferred Share equal to $1,000, plus the accrued premium
     thereon.

          10.  Restriction on Redemption and Cash Dividends with respect to
     Other Capital Stock. Until all of the Preferred Shares have been converted
     or redeemed as provided herein, except as permitted in the Rights
     Agreement, the Company shall not, directly or indirectly, redeem, or
     declare or pay any cash dividend or cash distribution on, its Common Stock
     without the prior express written consent of the holders of not less than
     two-thirds (2/3) of the then outstanding Preferred Shares.

          11.  Limitation on Number of Conversion Shares.  Notwithstanding any
     other provision herein, the Company shall not be obligated to issue any
     shares of Common Stock upon conversion of the Preferred Shares and Pari
     Passu Shares if the issuance of such shares of Common Stock would exceed
     that number of shares of Common Stock which the Company may issue upon
     Conversion of the Preferred Shares and Pari Passu Shares (the "EXCHANGE
     CAP") without breaching the Company's obligations under the rules or
     regulations of The Nasdaq Stock Market, Inc., except that such limitation
     shall not apply in the event that the Company (a) obtains the approval of
     its stockholders as required by NASD Rule 4460 (or any successor rule or
     regulation) for issuances of Common Stock in excess of such amount or (ii)
     obtains a written opinion from outside counsel to the Company that such
     approval is not required, which opinion shall be reasonably satisfactory to
     the holders of a majority of the Preferred Shares then outstanding. Until
     such approval or written opinion is obtained, no purchaser of Preferred
     Shares and Pari Passu Shares pursuant to the Purchase Agreement (the
     "PURCHASERS") shall be issued, upon conversion of Preferred Shares and Pari
     Passu Shares, shares of Common Stock in an amount greater than the product
     of (i) the Exchange Cap 

                                       19
<PAGE>
 
     amount multiplied by (ii) a fraction, the numerator of which is the number
     of Preferred Shares and Pari Passu Shares issued to such Purchaser pursuant
     to the Purchase Agreement and the denominator of which is the aggregate
     amount of all the Preferred Shares and Pari Passu Shares issued to the
     Purchasers pursuant to the Purchase Agreement (the "CAP ALLOCATION
     AMOUNT"). In the event that any Purchaser shall sell or otherwise transfer
     any of such Purchaser's Preferred Shares and Pari Passu Shares, the
     transferee shall be allocated a pro rata portion of such Purchaser's Cap
     Allocation Amount. In the event that any holder of Preferred Shares and
     Pari Passu Shares shall convert all of such holder's Preferred Shares and
     Pari Passu Shares into a number of shares of Common Stock which, in the
     aggregate, is less than such holder's Cap Allocation Amount, then the
     difference between such holder's Cap Allocation Amount and the number of
     shares of Common Stock actually issued to such holder shall be allocated to
     the respective Cap Allocation Amounts of the remaining holders of Preferred
     Shares and Pari Passu Shares on a pro rata basis in proportion to the
     number of Preferred Shares then held by each such holder.


          12.  Vote to Change the Terms of Preferred Shares. The affirmative
     vote at a meeting duly called for such purpose or the written consent
     without a meeting, of the holders of not less than two-thirds (2/3) of the
     then outstanding Preferred Shares and Pari Passu Shares, shall be required
     for any change to this Statement of Designations or the Company's
     Certificate of Incorporation which would amend, alter, change or repeal any
     of the powers, designations, preferences and rights of the Preferred
     Shares.

          13.  Lost or Stolen Certificates. Upon receipt by the Company of
     evidence satisfactory to the Company of the loss, theft, destruction or
     mutilation of any Preferred Stock Certificates representing the Preferred
     Shares, and, in the case of loss, theft or destruction, of any
     indemnification undertaking by the holder to the Company and, in the case
     of mutilation, upon surrender and cancellation of the Preferred Stock
     Certificate(s), the Company shall execute and deliver new preferred stock
     certificate(s) of like tenor and date; provided, however, the Company shall
     not be obligated to re-issue preferred stock certificates if the holder
     contemporaneously requests the Company to convert such Preferred Shares
     into Common Stock.

          14.  Remedies, Characterizations, Other Obligations, Breaches and
     Injunctive Relief. The remedies provided in this Statement of Designations
     shall be cumulative and in addition to all other remedies available under
     this Statement of Designations, at law or in equity (including a decree of
     specific performance and/or other injunctive relief), no remedy contained
     herein shall be deemed a waiver of compliance with the provisions giving
     rise to such remedy and nothing herein shall limit a holder's right to
     pursue actual damages for any failure by the Company to comply with the
     terms of this Statement of Designations. The Company covenants to each
     holder of Preferred Shares that there shall be no characterization
     concerning this instrument other than as expressly provided herein. Amounts
     set forth or provided for herein with respect to payments, conversion and
     the like (and the computation thereof) shall be the amounts to be received
     by the holder thereof and shall not, except as expressly provided herein,
     be subject to any other obligation of the Company (or the performance
     thereof). The Company acknowledges that a breach by it of its obligations
     hereunder will cause irreparable harm to the holders of the Preferred
     Shares and that the remedy at law for any such breach may 

                                       20
<PAGE>
 
     be inadequate. The Company therefore agrees that, in the event of any such
     breach or threatened breach, the holders of the Preferred Shares shall be
     entitled, in addition to all other available remedies, to an injunction
     restraining any breach, without the necessity of showing economic loss and
     without any bond or other security being required.

          15.  Specific Shall Not Limit General; Construction. No specific
     provision contained in this Statement of Designations shall limit or modify
     any more general provision contained herein. This Statement of Designations
     shall be deemed to be jointly drafted by the Company and all holders of
     Preferred Shares and shall not be construed against any person as the
     drafter hereof.

          16.  Failure or Indulgence Not Waiver. No failure or delay on the part
     of a holder of Preferred Shares in the exercise of any power, right or
     privilege hereunder shall operate as a waiver thereof, nor shall any single
     or partial exercise of any such power, right or privilege preclude other or
     further exercise thereof or of any other right, power or privilege.

                           STATEMENT OF DESIGNATION,
                            PREFERENCES AND RIGHTS

                                      OF

                     SERIES E CONVERTIBLE PREFERRED STOCK

                                      OF

                                DATA RACE, INC.

                        Pursuant to Article 2.13 of the
                        Texas Business Corporation Act


     Data Race, Inc., a corporation organized and existing under the Texas
Business Corporation Act (the "COMPANY"), does hereby certify that the following
resolutions were adopted by the Board of Directors of the Company on July 20,
1998 pursuant to authority of the Board of Directors as required by Article 2.13
of the Texas Business Corporation Act.

          RESOLVED, that pursuant to the authority granted to and vested in the
     Board of Directors of this Company (the "BOARD OF DIRECTORS" or the
     "BOARD") in accordance with the provisions of its Articles of
     Incorporation, the Board of Directors hereby authorizes a series of the
     Company's previously authorized preferred Stock, no par value (the
     "PREFERRED STOCK"), and hereby states the designation and number of shares,
     and fixes the relative rights, preferences, privileges, powers and
     restrictions thereof as follows:

          Series E Convertible Preferred Stock:

          17.  Designation, Amount and Dividends.  The designation of this
     series, which consists of 750 shares of Preferred Stock, is the Series E
     Convertible Preferred Stock (the "PREFERRED SHARES") and the stated value
     shall be One Thousand Dollars ($1,000.00) per share (the "STATED VALUE").
     The Preferred Shares shall not bear any dividends.

                                       1
<PAGE>
 
          18.  Holder's Conversion of Preferred Shares.  A holder of Preferred
     Shares shall have the right, at such holder's option, to convert the
     Preferred Shares into shares of the Company's common stock, no par value
     per share (the "COMMON STOCK"), on the following terms and conditions:

               a.   Conversion Right.  Subject to the provisions of Section 11
     below, at any time or times on or after the earliest of the first
     anniversary of the Issuance Date (as defined below), the Mandatory
     Conversion Date (as defined below) or the occurrence of a Triggering Event
     (as defined below), any holder of Preferred Shares shall be entitled to
     convert any whole number of Preferred Shares into fully paid and
     nonassessable shares (rounded to the nearest whole share in accordance with
     Section 2(i) below) of Common Stock, at the Conversion Rate (as defined
     below); provided, however, that in no event shall any holder be entitled to
     convert Preferred Shares in excess of that number of Preferred Shares
     which, upon giving effect to such conversion, 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 conversion. 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 conversion of the Preferred Shares with respect to which the
     determination of such proviso is being made, but shall exclude the number
     of shares of Common Stock which would be issuable upon (i) conversion of
     the remaining, nonconverted Preferred Shares beneficially owned by the
     holder and its affiliates and (ii) exercise or conversion of the
     unexercised or unconverted portion of any other securities of the Company
     (including, without limitation, any warrants) subject to a limitation on
     conversion or exercise analogous to the limitation contained herein
     beneficially owned by the holder and its affiliates. 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. Each holder may waive the
     foregoing limitation with respect to its conversions by written notice to
     the Company upon not less than 61 days prior notice (with such waiver
     taking effect only upon the expiration of such 61 day notice period), and
     such limitation shall not apply to conversions as of the Mandatory
     Conversion Date.

               b.   Conversion Rate. Subject to the other provisions hereof,
     each of the Preferred Shares shall be convertible, at the option of the
     holder, into that number of shares of fully paid and nonassessable shares
     of Common Stock which is to be derived from dividing the Stated Value by
     the Conversion Price (the "Conversion Rate).
 
     For purposes of this Statement of Designation, the following terms shall
have the following meanings:

               The "CLOSING BID PRICE" shall mean, for any security as of any
date, the last closing bid price for such security on the Nasdaq National Market
as reported by Bloomberg Financial Markets ("BLOOMBERG"), or, if the Nasdaq
National Market is not the principal trading market for such security, the last
closing bid price of such security on the principal securities exchange or
trading market where such security is listed or traded as reported by Bloomberg,
or if the foregoing do not apply, the last closing bid price of such security in
the over-the-counter market on the electronic bulletin board for such security
as reported by Bloomberg, or, if no closing bid price is reported for

                                       2
<PAGE>
 
such security by Bloomberg, the last closing trade price of such security as
reported by Bloomberg, or, if no last closing trade price is reported for such
security by Bloomberg, the average of the bid prices of any market makers for
such security as reported in the "pink sheets" by the National Quotation Bureau,
Inc. If the Closing Bid Price cannot be calculated for such security on such
date on any of the foregoing bases, the Closing Bid Price of such security on
such date shall be the fair market value as mutually determined by the Company
and the holders of a majority of the outstanding Preferred Shares. If the
Company and the holders of Preferred Shares are unable to agree upon the fair
market value of the Common Stock, then such dispute shall be resolved pursuant
to Section 2(g)(iii) below with the term "Closing Bid Price" being substituted
for the term "Market Price". To the extent required hereunder, all such
determinations of the Closing Bid Price shall be appropriately adjusted for any
stock dividend, stock split or other similar transaction.

                    "CONVERSION PRICE" means, as of any Conversion Date (as
defined below) or other date of determination, the Fixed Conversion Price.

                    "FIXED CONVERSION PRICE" means One ($1.00) Dollar, subject
to adjustment as provided herein.

                    "ISSUANCE DATE" shall mean, with respect to each Preferred
Share, the date of issuance of the applicable Preferred Share.

                    "MARKET PRICE" shall mean, with respect to any security for
any date, the arithmetic average of the Closing Bid Price for such security on
each of the five consecutive trading days immediately preceding such date.

               c.   Premium.  The Preferred Shares shall bear a non-compounding
premium at the rate of eight (8%) percent per annum. Accrual of such premium
shall commence on the Issuance Date. The premium on each Preferred Share shall
be payable by the Company upon conversion of the Preferred Share, at the
Company's option, in cash or, subject to the Exchange Cap as provided in Section
11, in shares of Common Stock (valued at the Market Price on the Conversion
Date) which have been previously registered by the Company for resale by the
holder of the Preferred Shares. The premium on each Preferred Share shall be
payable solely in cash by the Company upon redemption thereof or liquidation.

               d.   Adjustment to Conversion Price -- Dilution and Other Events.
In order to prevent dilution of the rights granted under this Statement of
Designation, the Conversion Price will be subject to adjustment from time to
time as provided in this Section 2(d).

                    (i)    Adjustment of Fixed Conversion Price upon Issuance of
Common Stock. If and whenever on or after the date of issuance of the Preferred
Shares, the Company issues or sells, or is deemed to have issued or sold, any
shares of Common Stock (other than shares of Common Stock deemed to have been
issued by the Company in connection with Approved Issuances (as defined below))
for a consideration per share less than the Market Price in effect immediately
prior to such time (the "APPLICABLE PRICE"), then immediately after such issue
or sale, the Fixed Conversion Price shall be reduced to an amount equal to the
product of (x) the Fixed Conversion Price in effect immediately prior to such
issue or sale and (y) the quotient determined by dividing (1) the sum of

                                       3
<PAGE>
 
(I) the product of the Applicable Price and the number of shares of Common Stock
Deemed Outstanding (as defined below) immediately prior to such issue or sale,
and (II) the consideration, if any, received by the Company upon such issue or
sale, by (2) the product of (I) the Applicable Price and (II) the number of
shares of Common Stock Deemed Outstanding immediately after such issue or sale.
For purposes of determining the adjusted Fixed Conversion Price under this
Section 2(d)(i), the following shall be applicable:

                           (A)  Issuance of Options.  If the Company in any
     manner grants any rights or options to subscribe for or to purchase Common
     Stock (other than in connection with an Approved Issuance or upon
     conversion of the Preferred Shares) or any stock or other securities
     convertible into or exchangeable for Common Stock (such rights or options
     being herein called "OPTIONS" and such convertible or exchangeable stock or
     securities being herein called "CONVERTIBLE SECURITIES") and the price per
     share for which Common Stock is issuable upon the exercise of such Options
     or upon conversion or exchange of such Convertible Securities is less than
     the Applicable Price, then the total maximum number of shares of Common
     Stock issuable upon the exercise of such Options or upon conversion or
     exchange of the total maximum amount of such Convertible Securities
     issuable upon the exercise of such Options shall be deemed to be
     outstanding and to have been issued and sold by the Company for such price
     per share. For purposes of this Section 2(d)(i)(A), the "price per share
     for which Common Stock is issuable upon exercise of such Options or upon
     conversion or exchange of such Convertible Securities" is determined by
     dividing (I) the total amount, if any, received or receivable by the
     Company as consideration for the granting of such Options, plus the minimum
     aggregate amount of additional consideration payable to the Company upon
     the exercise of all such Options, plus in the case of such Options which
     relate to Convertible Securities, the minimum aggregate amount of
     additional consideration, if any, payable to the Company upon the issuance
     or sale of such Convertible Securities and the conversion or exchange
     thereof, by (II) the total maximum number of shares of Common Stock
     issuable upon exercise of such Options or upon the conversion or exchange
     of all such Convertible Securities issuable upon the exercise of such
     Options. No adjustment of the Fixed Conversion 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 or exchange of such Convertible Securities.

                           (B)  Issuance of Convertible Securities.  If the
     Company in any manner issues or sells any Convertible Securities and the
     price per share for which Common Stock is issuable upon such conversion or
     exchange is less than the Applicable Price, then the maximum number of
     shares of Common Stock issuable upon conversion or exchange of such
     Convertible Securities shall be deemed to be outstanding and to have been
     issued and sold by the Company for such price per share. For the purposes
     of this Section 2(d)(i)(B), the "price per share for which Common Stock is
     issuable upon such conversion or exchange" is determined by dividing (I)
     the total amount received or receivable by the Company as consideration for
     the issue or sale of such Convertible Securities, plus the minimum
     aggregate amount of additional consideration, if any, payable to the
     Company upon the conversion or exchange thereof, by (II) the total maximum
     number of shares of Common Stock issuable upon the conversion or exchange
     of all such Convertible Securities. No adjustment of the Fixed Conversion
     Price shall be made upon the actual issue of such Common Stock upon
     conversion

                                       4
<PAGE>
 
     or exchange 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 Fixed Conversion Price had been or are to be made
     pursuant to other provisions of this Section 2(d)(i), no further adjustment
     of the Fixed Conversion Price shall be made by reason of such issue or
     sale.

                           (C)  Change in Option Price or Rate of Conversion.  
     If the purchase price provided for in any Options, the additional
     consideration, if any, payable upon the issue, conversion or exchange of
     any Convertible Securities, or the rate at which any Convertible Securities
     are convertible into or exchangeable for Common Stock change at any time,
     the Fixed Conversion Price in effect at the time of such change shall be
     readjusted to the Fixed Conversion Price which would have been in effect at
     such time had such Options or Convertible Securities still outstanding
     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; provided that no adjustment shall be made if such
     adjustment would result in an increase of the Fixed Conversion Price then
     in effect.

                           (D)  Certain Definitions.  For purposes of
     determining the adjusted Fixed Conversion Price under this Section 2(d)(i),
     the following terms have meanings set forth below:

                                (I)  "APPROVED ISSUANCES" shall mean (i) a loan
     from a commercial bank, (ii) any transaction involving the Company's
     issuances of securities (A) as consideration in a merger or consolidation
     or (B) as consideration for the acquisition of a business, product or
     license or other assets by the Company, (iii) the issuance of Common Stock
     in a firm commitment, underwritten public offering, (iv) the issuance of
     securities upon exercise or conversion of the Company's options, warrants
     or other convertible securities outstanding as of the date hereof, (v) the
     grant of additional options or warrants, or the issuance of additional
     securities, under any Company stock option plan, restricted stock plan,
     stock purchase plan or other plan or written compensation contract for the
     benefit of the Company's employees, consultants or directors, (vi) the
     issuance of securities pursuant to the Rights Agreement, dated September
     15, 1997, between the Company and ChaseMellon Shareholder Services, L.L.C.,
     as amended from time to time in accordance with its terms (the "Rights
     Agreement"), and (vii) the issuance of securities pursuant to the Purchase
     Agreement, or in connection with any of the transactions related thereto.

                                (II) "COMMON STOCK DEEMED OUTSTANDING" means, at
     any given time, the number of shares of Common Stock actually outstanding
     at such time, plus the number of shares of Common Stock deemed to be
     outstanding pursuant to Sections 2(d)(i)(A) and 2(d)(i)(B) hereof
     regardless of whether the Options or Convertible Securities are actually
     exercisable at such time, but excluding any shares of Common Stock issuable
     upon conversion of the Preferred Shares.

                           (E)  Treatment of Expired Options and Unexercised
     Convertible Securities.  If, in any case, the total number of shares of
     Common Stock issuable upon the exercise of any Option or upon exercise,
     conversion or exchange of any Convertible Security is not, in fact, issued
     and the rights to exercise such Option or to exercise, convert or 

                                       5
<PAGE>
 
     exchange such Convertible Securities shall have expired or terminated, the
     Fixed Conversion Price then in effect will be readjusted to the Fixed
     Conversion Price which would have been effect at the time of such
     expiration or termination had such Option or Convertible Securities, to the
     extent outstanding immediately prior to such expiration or termination
     (other than in respect of the actual number of shares of Common Stock
     issued upon exercise or conversion thereof), never been issued.

                           (F)  Effect on Fixed Conversion Price of Certain
     Events.  For purposes of determining the adjusted Fixed Conversion Price
     under this Section 2(d)(i), the following shall be applicable:

                                (I)   Calculation of Consideration Received.  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 amount received by the Company therefor,
     before deduction of reasonable commissions, underwriting discounts or
     allowances or other reasonable expenses paid or incurred by the Company in
     connection with such issuance or sale. In case any Common Stock, Options or
     Convertible Securities are issued or sold for a consideration other than
     cash, the amount of the consideration other than cash received by the
     Company will be the fair value of such consideration, except where such
     consideration consists of securities, in which case the amount of
     consideration received by the Company will be the Market Price of such
     security on the date of receipt. In case 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 a
     majority of the Preferred Shares 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 forty-eight (48) hours of the tenth
     (10th) day following the Valuation Event by an independent, reputable
     appraiser selected by the Company. The determination of such appraiser
     shall be deemed binding upon all parties absent manifest error.

                                (II)  Integrated Transactions.  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
     for purposes of Section 2(d)(i)(A).

                                (III) Treasury Shares.  The number of shares of
     Common Stock outstanding at any given time does not include shares owned or
     held by or for the account of the Company, and the disposition of any
     shares so owned or held will be considered an issue or sale of Common
     Stock.

                                       6
<PAGE>
 
                                (IV)  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 (assuming such
     issuance ultimately occurs).

                    (ii)   Adjustment of Fixed Conversion Price upon Subdivision
     or Combination of Common Stock. If the Company at any time subdivides (by
     any stock split, stock dividend, recapitalization or otherwise) one or more
     classes of its outstanding shares of Common Stock into a greater number of
     shares, the Fixed Conversion Price in effect immediately prior to such
     subdivision will be proportionately reduced. If the Company at any time
     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 Fixed Conversion Price in effect immediately prior to such
     combination will be proportionately increased.

                    (iii)  Intentionally omitted.
 
                    (iv)   Reorganization, Reclassification, Consolidation,
     Merger or Sale. Any recapitalization, reorganization, reclassification,
     consolidation, merger, sale of all or substantially all of the Company's
     assets to another Person (as defined below) or other transaction which is
     effected in such a way that holders of Common Stock are entitled to receive
     (either directly or upon subsequent liquidation) stock, securities or
     assets with respect to or in exchange for Common Stock, other than a Major
     Transaction, is referred to herein as "ORGANIC CHANGE." Prior to the
     consummation of any Organic Change, the Company will appropriate provision
     (in form and substance reasonably satisfactory to the holders of a majority
     of the Preferred Shares then outstanding) to insure that each of the
     holders of the Preferred Shares will thereafter have the right to acquire
     and receive in lieu of or addition to (as the case may be) the shares of
     Common Stock otherwise acquirable and receivable upon the conversion of
     such holder's Preferred Shares, 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 conversion of such holder's
     Preferred Shares had such Organic Change not taken place (without taking
     into account any limitations or restrictions on the timing or amount of
     conversions). In any such case, the Company will make appropriate provision
     (in form and substance reasonably satisfactory to the holders of a majority
     of the Preferred Shares then outstanding) with respect to such holders'
     rights and interests to insure that the provisions of this Section 2(d) and
     Section 2(e) below will thereafter be applicable to the Preferred Shares
     (including, in the case of any such consolidation, merger or sale in which
     the successor entity or purchasing entity is other than the Company, an
     immediate adjustment of the Fixed Conversion Price to the value for the
     Common Stock reflected by the terms of such consolidation, merger or sale,
     if the value so reflected is less than the Fixed Conversion Price in effect
     immediately prior to such consolidation, merger or sale). The Company will
     not effect any such consolidation, merger or sale, other than a Major
     Transaction, unless prior to the

                                       7
<PAGE>
 
     consummation thereof, the successor entity (if other than the Company)
     resulting from consolidation or merger or the entity purchasing such assets
     assumes, by written instrument, the obligation to deliver to each holder of
     Preferred Shares such shares of stock, securities or assets as, in
     accordance with the foregoing provisions, such holder may be entitled to
     acquire. "PERSON" shall mean an individual, a limited liability company, a
     partnership, a joint venture, a corporation, a trust, an unincorporated
     organization and a government or any department or agency thereof.

                    (v)    Certain Events.  If any event occurs of the type
     contemplated by the provisions of this Section 2(d) 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 Conversion Price so as to protect the rights
     of the holders of the Preferred Shares; provided that no such adjustment
     will increase the Conversion Price as otherwise determined pursuant to this
     Section 2(d).

                    (vi)   Notices.

                           (A)  Immediately upon any adjustment of the
     Conversion Price, the Company will give written notice thereof to each
     holder of Preferred Shares, setting forth in reasonable detail and
     certifying the calculation of such adjustment.

                           (B)  The Company will give written notice to each
     holder of Preferred Shares at least twenty (20) days prior to the date on
     which the Company closes its books or takes a record (I) with respect to
     any dividend or distribution upon the Common Stock, (II) with respect to
     any pro rata subscription offer to holders of Common Stock or (III) for
     determining rights to vote with respect to any Organic Change, dissolution
     or liquidation and in no event shall such notice be provided to such holder
     prior to such information being made known to the public.

                           (C)  The Company will also give written notice to
     each holder of Preferred Shares at least twenty (20) days prior to the date
     on which any Organic Change, dissolution or liquidation will take place and
     in no event shall such notice be provided to such holder prior to such
     information being made known to the public.

               e.   Purchase Rights.  In addition to any adjustments of the
Conversion Price pursuant to Section 2(d) above, if at any time after the
Issuance Date 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 holders of Preferred Shares 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 conversion of the Preferred
Shares (without taking into account any limitations or restrictions on the
timing or amount of conversions) 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.

               f.   [Intentionally omitted.]

               g.   Mechanics of Conversion.  Subject to the Company's inability
to fully satisfy its obligations under a Conversion Notice (as defined below) as
provided for in Section 4 below:

                    (i)    Holder's Delivery Requirements.  To convert Preferred
     Shares into full shares of Common Stock on any date (the "CONVERSION
     DATE"), the holder thereof shall (A) transmit by facsimile (or otherwise
     deliver), for receipt on or prior to 11:59 p.m., Eastern Time on such date,
     a copy of a fully executed notice of conversion in the form attached hereto
     as Exhibit I (the "CONVERSION NOTICE"), to the Company, and (B) surrender
     to a common carrier for delivery to the Company as soon as practicable
     following such date, the original certificates representing the Preferred
     Shares being converted (or an indemnification undertaking with respect to
     such shares in the case of their loss, theft or destruction) (the
     "PREFERRED STOCK CERTIFICATES") and the originally executed Conversion
     Notice.

                    (ii)   Company's Response.  Upon receipt by the Company of a
     facsimile copy of a Conversion Notice, the Company shall immediately send,
     via facsimile, a confirmation of receipt of such Conversion Notice to such
     holder. Upon receipt by the Company of the Preferred Stock Certificates to
     be converted pursuant to a Conversion Notice, together with the originally
     executed Conversion Notice, the Company or its designated transfer agent
     (the "TRANSFER AGENT") (as applicable) shall, on the next business day
     following the date of receipt of both (or the second business day following
     the date of receipt of both if received after 11:00 a.m. local time of the
     Company), (I) issue and surrender to a common carrier for overnight
     delivery to the address as specified in the Conversion 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, or
     (II) 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 The Depository Trust Company. If the number of Preferred Shares
     represented by the Preferred Stock Certificate(s) submitted for conversion
     is greater than the number of Preferred Shares being converted, then the
     Company shall, as soon as practicable and in no event later than two
     business days after receipt of the Preferred Stock Certificate(s) and at
     its own expense, issue and deliver to the holder a new Preferred Stock
     Certificate representing the number of Preferred Shares not converted.

                    (iii)  Dispute Resolution.  In the case of a dispute as to
     the determination of the Market Price or the arithmetic calculation of the
     Conversion Rate, 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 as soon as possible, but in no event later than two (2) business
     days after receipt of such holder's Conversion Notice. If such holder and
     the Company are unable to agree upon the determination of the Market Price
     or arithmetic calculation of the Conversion Rate within one (1) business
     day of such disputed determination or arithmetic calculation being
     submitted to the holder, then the Company shall within one (1) business day
     submit via facsimile (A) the disputed determination of the Market Price to
     an independent, reputable investment bank or (B) the disputed arithmetic
     calculation of the Conversion Rate to its independent, outside

                                       9

     accountant. The Company shall cause the investment bank 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 forty-eight
     (48) hours from the time it receives the disputed determinations or
     calculations. Such investment bank's or accountant's determination or
     calculation, as the case may be, shall be binding upon all parties absent
     manifest error. The period of time in which the Company is required to
     effect conversions or redemptions under this Statement of Designations
     shall be tolled with respect to the subject conversion or redemption
     pending resolution of any dispute by the Company made in good faith and in
     accordance with this Section 2(g)(iii).

                    (iv)   Record Holder.  The person or persons entitled to
     receive the shares of Common Stock issuable upon a conversion of Preferred
     Shares shall be treated for all purposes as the record holder or holders of
     such shares of Common Stock on the Conversion Date.

                    (v)    Company's Failure to Timely Convert.  If within three
     (3) business days of the Company's receipt of the Conversion Notice (the
     "SHARE DELIVERY PERIOD") the Company shall fail to issue a certificate to a
     holder for the number of shares of Common Stock to which such holder is
     entitled upon such holder's conversion of Preferred Shares or to issue a
     new Preferred Stock Certificate representing the number of Preferred Shares
     to which such holder is entitled pursuant to Section 2(g)(ii) (a
     "CONVERSION FAILURE"), in addition to all other available remedies which
     such holder may pursue hereunder and under the Purchase Agreement between
     the Company and the initial holders of the Preferred Shares (the " PURCHASE
     AGREEMENT") (including indemnification), the Company shall pay additional
     damages to such holder for each business day after such third (3rd)
     business day that such conversion is not timely effected in an amount equal
     to two (2%) percent per month of the product of (A) the number of shares of
     Common Stock not issued to the holder on a timely basis pursuant to Section
     2(g)(ii) and to which such holder is entitled, and (B) the Closing Bid
     Price of the Common Stock on the last possible date which the Company could
     have issued such Common Stock to such holder without violating Section
     2(g)(ii). If the Company fails to pay the additional damages set forth in
     this Section 2(g)(v) within five business days of the date incurred, then
     the holder entitled to such payments shall have the right at any time, so
     long as the Company continues to fail to make such payments, to require the
     Company, upon written notice, to immediately issue, in lieu of the cash
     additional damages set forth in this Section 2(g)(v), the number of shares
     of Common Stock equal to the quotient of (X) the aggregate amount of the
     additional damages payments described above divided by (Y) the Market Price
     in effect on such Conversion Date as is specified by the holder in writing
     to the Company. Payment of the additional damages shall not relieve the
     Company of its obligation to send the shares of Common Stock to the holder
     upon conversion.

               h.   Mandatory Conversion.  Subject to Section 11, if any
     Preferred Shares remain outstanding on the Mandatory Conversion Date (as
     defined below), then all such Preferred Shares shall be converted as of
     such date in accordance with this Section 2 as if the holders of such
     Preferred Shares had given the Conversion Notice on the Mandatory
     Conversion Date; provided, however, that if a Triggering Event has occurred
     and is continuing on the Mandatory Conversion Date, then the Company shall,
     within five business days

                                       10
<PAGE>
 
     following the Mandatory Conversion Date (unless otherwise notified in
     writing by the holder of its request to have the Preferred Shares converted
     into Common Stock), pay to each holder of Preferred Shares then
     outstanding, in immediately available funds, an amount equal to the
     Triggering Event Redemption Price as of the Mandatory Conversion Date. All
     holders of Preferred Shares shall thereupon surrender all Preferred Stock
     Certificates, duly endorsed for cancellation, to the Company or the
     Transfer Agent, provided that the Company has complied with its obligations
     under this Section 2(h). Notwithstanding the foregoing, except in the case
     of a Major Transaction, if the Common Stock is not designated for quotation
     on the Nasdaq National Market or listed on The New York Stock Exchange,
     Inc. or The American Stock Exchange, Inc. but such events do not constitute
     a Triggering Event, then the Mandatory Conversion Date shall be extended
     until the Common Stock is so designated or listed. "MANDATORY CONVERSION
     DATE" means the date which is the earlier of five years after the
     applicable Issuance Date, subject to extension as described in the
     immediately preceding sentence, or immediately prior to a Major
     Transaction.

               i.   Fractional Shares.  The Company shall not issue any fraction
     of a share of Common Stock upon any conversion. All shares of Common Stock
     (including fractions thereof) issuable upon conversion of more than one
     Preferred Share by a holder thereof shall be aggregated for purposes of
     determining whether the conversion would result in the issuance of a
     fraction of a share of Common Stock. If, after the aforementioned
     aggregation, the issuance would result in the issuance of a fraction of a
     share of Common Stock, the Company shall round such fraction of a share of
     Common Stock up or down to the nearest whole share.

               j.   Taxes.  The Company shall pay any and all taxes which may be
     imposed upon it with respect to the issuance and delivery of Common Stock
     upon the conversion of the Preferred Shares.

          19.  Redemption at Option of Holders.

               a.   Redemption Option Upon Major Transaction.  In addition to
     all other rights of the holders of Preferred Shares contained herein,
     simultaneous with the occurrence of a Major Transaction (as defined below),
     each holder of Preferred Shares shall have the right, at such holder's
     option, to require the Company to redeem all or a portion of such holder's
     Preferred Shares at a price per Preferred Share equal to 120% of the
     Liquidation Preference (as defined in Section 8 below) ("MAJOR TRANSACTION
     REDEMPTION PRICE").

               b.   Redemption Option Upon Triggering Event.  In addition to all
     other rights of the holders of Preferred Shares contained herein, after a
     Triggering Event (as defined below), each holder of Preferred Shares shall
     have the right, at such holder's option, to require the Company to redeem
     all or a portion of such holder's Preferred Shares at a price per Preferred
     Share equal to 120% of the Liquidation Preference ("TRIGGERING EVENT
     REDEMPTION PRICE" and, collectively with "MAJOR TRANSACTION REDEMPTION
     PRICE," the "REDEMPTION PRICE").

                                       11
<PAGE>
 
               c.   "Major Transaction".  A "MAJOR TRANSACTION" shall be deemed
     to have occurred at such time as any of the following events:

                    (i)    the consolidation, merger or other business
     combination of the Company with or into another Person which requires or
     receives the consent or recommendation of the Company's Board of Directors
     (excluding a consolidation, merger or other business combination in which
     holders of the Company's voting power immediately prior to the transaction
     continue after the transaction to hold, directly or indirectly, the voting
     power of the surviving entity or entities necessary to elect a majority of
     the members of the board of directors (or their equivalent if other than a
     corporation) of such entity or entities and excluding a short-form merger
     effected without the consent or recommendation of the Company's Board of
     Directors) (an "EXEMPT MAJOR TRANSACTION").

                    (ii)   the sale or transfer of all or substantially all of
     the Company's assets or rights to the "Be There!" business or product line
     other than in connection with a disposition to a subsidiary of the Company;
     or

                    (iii)  consummation of a purchase, tender or exchange offer
     made to the holders of more than 50% of the outstanding shares of Common
     Stock which requires or receives the consent or recommendation of the
     Company's Board of Directors.

               d.   "Triggering Event".  A "TRIGGERING EVENT" shall be deemed to
     have occurred at such time as any of the following events (other than in
     connection with a Major Transaction):

                    (i)    the failure of the Registration Statement to be
     declared effective by the SEC on or prior to the date that is 150 days
     after the Demand;

                    (ii)   while the Registration Statement is required to be
     maintained effective pursuant to the terms of the Registration Rights
     Agreement, the effectiveness of the Registration Statement lapses for any
     reason (including, without limitation, the issuance of a stop order) or is
     unavailable to the holder of the Preferred Shares for sale of all of the
     Registrable Securities (as defined in the Registration Rights Agreement) in
     accordance with the terms of the Registration Rights Agreement, and such
     lapse or unavailability continues for a period of thirty (30) consecutive
     trading days, provided that the cause of such lapse or unavailability is
     not due to factors solely within the control of such holder of Preferred
     Shares;

                    (iii)  the Company undertakes any voluntary action to
     terminate the quotation or listing of the Common Stock on the Nasdaq
     National Market, The New York Stock Exchange, Inc. or The American Stock
     Exchange, Inc., unless such action is taken in connection with the
     continued quotation or listing of the Common Stock on another of the Nasdaq
     National Market, The New York Stock Exchange, Inc. or The American Stock
     Exchange, Inc.;

                    (iv)   the Company's failure to deliver shares of Common
     Stock within 15 days of its receipt of a Conversion Notice (together with
     the Preferred Stock

                                       12
<PAGE>
 
     Certificate) or the Company's notice to any holder of Preferred Shares,
     including by way of public announcement, at any time, of its intention not
     to comply with proper requests for conversion of any Preferred Shares into
     shares of Common Stock, other than due to any of the reasons set forth in
     Section 4(a) below; or

                    (v)    if the Company pursuant to or within the meaning of
     Title 11, U.S. Code, or any similar federal or state law for the relief of
     debtors ("BANKRUPTCY LAW"), (I) commences a voluntary case, (II) consents
     to the entry of an order for relief against it in any involuntary case,
     (III) consents to the appointment of a receiver, trustee, assignee,
     liquidator or similar official under any Bankruptcy Law (a "CUSTODIAN") of
     it or for all or substantially all of its property, (IV) makes a general
     assignment for the benefit of its creditors, or (V) admits in writing that
     it is generally unable to pay its debts as the same become due.

               e.   Mechanics of Redemption at Option of Buyer Upon Major
     Transaction.  No sooner than 15 days nor later than 10 days prior to the
     consummation of a Major Transaction, but not prior to the public
     announcement of such Major Transaction, the Company shall deliver written
     notice thereof via facsimile and overnight courier ("NOTICE OF MAJOR
     TRANSACTION") to each holder of Preferred Shares. At any time after receipt
     of a Notice of Major Transaction (or, in the event a Notice of Major
     Transaction is not delivered at least 10 days prior to a Major Transaction,
     at any time within 10 days prior to a Major Transaction), any holder of
     Preferred Shares then outstanding may require the Company to redeem,
     effective immediately prior to the consummation of such Major Transaction,
     all of the holder's Preferred Shares then outstanding by delivering written
     notice thereof via facsimile and overnight courier ("NOTICE OF REDEMPTION
     AT OPTION OF BUYER UPON MAJOR TRANSACTION") to the Company, which Notice of
     Redemption at Option of Buyer Upon Major Transaction shall indicate (i) the
     number of Preferred Shares that such holder is electing to redeem and (ii)
     the applicable Major Transaction Redemption Price, as calculated pursuant
     to Section 3(a) above. Preferred Shares which are not required to be
     redeemed pursuant to this paragraph are subject to mandatory conversion as
     provided herein.

               f.   Mechanics of Redemption at Option of Buyer Upon Triggering
     Event.  Within one (1) day after the occurrence of a Triggering Event, the
     Company shall deliver written notice thereof via facsimile and overnight
     courier ("NOTICE OF TRIGGERING EVENT") to each holder of Preferred Shares.
     At any time after the earlier of a holder's receipt of a Notice of
     Triggering Event and such holder becoming aware of a Triggering Event, any
     holder of Preferred Shares then outstanding may require the Company to
     redeem all of the Preferred Shares by delivering written notice thereof via
     facsimile and overnight courier ("NOTICE OF REDEMPTION AT OPTION OF BUYER
     UPON TRIGGERING EVENT") to the Company, which Notice of Redemption at
     Option of Buyer Upon Triggering Event shall indicate (i) the number of
     Preferred Shares that such holder is electing to redeem and (ii) the
     applicable Triggering Event Redemption Price, as calculated pursuant to
     Section 3(b) above.

               g.   Payment of Redemption Price.  Upon the Company's receipt of
     a Notice(s) of Redemption at Option of Buyer Upon Triggering Event or a
     Notice(s) of Redemption at Option of Buyer Upon Major Transaction from any
     holder of Preferred Shares or Pari Passu Shares (as defined in Section 8),
     the Company shall immediately notify each

                                       13
<PAGE>
 
     holder of Preferred Shares and Pari Passu Shares by facsimile of the
     Company's receipt of such Notice(s) of Redemption at Option of Buyer Upon
     Triggering Event or Notice(s) of Redemption at Option of Buyer Upon Major
     Transaction and each holder which has sent such a notice shall promptly
     submit to the Company or its Transfer Agent such holder's Preferred Stock
     Certificates which such holder has elected to have redeemed. The Company
     shall deliver the applicable Triggering Event Redemption Price, in the case
     of a redemption pursuant to Section 3(f), to such holder within five
     business days after the Company's receipt of a Notice of Redemption at
     Option of Buyer Upon Triggering Event and, in the case of a redemption
     pursuant to Section 3(e), the Company shall deliver the applicable Major
     Transaction Redemption Price immediately prior to the consummation of the
     Major Transaction; provided that a holder's Preferred Stock Certificates
     shall have been so delivered to the Company; provided further that if the
     Company is unable to redeem all of the Preferred Shares and Pari Passu
     Shares to be redeemed (because of insufficient funds to lawfully effect
     such redemption), the Company shall redeem an amount from each holder of
     Preferred Shares and Pari Passu Shares being redeemed equal to such
     holder's pro-rata amount (based on the relative redemption amounts of all
     holders of Preferred Shares and Pari Passu Shares) of all Preferred Shares
     and Pari Passu Shares being redeemed. If the Company shall fail to redeem
     all of the Preferred Shares submitted for redemption (other than pursuant
     to a dispute as to the arithmetic calculation of the Redemption Price), in
     addition to any remedy such holder of Preferred Shares may have under this
     Statement of Designations and the Purchase Agreement, the applicable
     Redemption Price payable in respect of such unredeemed Preferred Shares
     shall bear interest at the rate of 2.0% per month (prorated for partial
     months) until paid in full. Until the Company pays such unpaid applicable
     Redemption Price in full to a holder of Preferred Shares submitted for
     redemption, such holder shall have the option (the "VOID OPTIONAL
     REDEMPTION OPTION") to, in lieu of redemption, require the Company to
     promptly return to such holder(s) all of the Preferred Shares that were
     submitted for redemption by such holder(s) under this Section 3 and for
     which the applicable Redemption Price has not been paid, by sending written
     notice thereof to the Company via facsimile (the "VOID OPTIONAL REDEMPTION
     NOTICE"). Upon the Company's receipt of such Void Optional Redemption
     Notice(s) and prior to payment of the full applicable Redemption Price to
     such holder, (i) the Notice(s) of Redemption at Option of Buyer Upon
     Triggering Event or the Notice(s) of Redemption at Option of Buyer Upon
     Major Transaction, as the case may be, shall be null and void with respect
     to those Preferred Shares submitted for redemption and for which the
     applicable Redemption Price has not been paid, and (ii) the Company shall
     immediately return any Preferred Shares submitted to the Company by each
     holder for redemption under this Section 3(g) and for which the applicable
     Redemption Price has not been paid. Notwithstanding the foregoing, in the
     event of a dispute as to the determination of the Closing Bid Price or the
     arithmetic calculation of the Redemption Price, such dispute shall be
     resolved pursuant to Section 2(g)(iii) above with the term "Closing Bid
     Price" being substituted for the term "Average Market Price" and the term
     "Redemption Price" being substituted for the term "Conversion Rate". A
     holder's delivery of a Void Optional Redemption Notice and exercise of its
     rights following such notice shall not affect the Company's obligations to
     make any payments which have accrued prior to the date of such notice.
     Payments provided for in this Section 3 shall have priority to payments to
     other stockholders, other than any required payments with respect to shares
     of the Company's Series A Convertible Preferred Stock which were
     outstanding on the Issuance Date, in connection with a Major Transaction.

                                       14

          20.  Inability to Fully Convert.

               a.   Holder's Option if Company Cannot Fully Convert.  If, upon
     the Company's receipt of a Conversion Notice or on the Mandatory Conversion
     Date, the Company can not issue shares of Common Stock registered for
     resale under the Registration Statement for any reason, including, without
     limitation, because the Company (x) does not have a sufficient number of
     shares of Common Stock authorized and available, (y) is otherwise
     prohibited by applicable law or by the rules or regulations of any stock
     exchange, interdealer quotation system or other self-regulatory
     organization with jurisdiction over the Company or its Securities,
     including without limitation the Exchange Cap, from issuing all of the
     Common Stock which is to be issued to a holder of Preferred Shares pursuant
     to a Conversion Notice or (z) fails to have a sufficient number of shares
     of Common Stock registered for resale under the Registration Statement,
     then the Company shall issue as many shares of Common Stock as it is able
     to issue in accordance with such holder's Conversion Notice and pursuant to
     Section 2(g) above and, with respect to the unconverted Preferred Shares,
     the holder, solely at such holder's option, can elect to:

                    (i)    require the Company to redeem from such holder those
     Preferred Shares for which the Company is unable to issue Common Stock in
     accordance with such holder's Conversion Notice ("MANDATORY REDEMPTION") at
     a price per Preferred Share (the "MANDATORY REDEMPTION PRICE") equal to the
     Triggering Event Redemption Price as of such Conversion Date;

                    (ii)   if the Company's inability to fully convert Preferred
     Shares is pursuant to Section 4(a)(z) above, require the Company to issue
     restricted shares of Common Stock in accordance with such holder's
     Conversion Notice and pursuant to Section 2(g) above;

                    (iii)  void its Conversion Notice and retain or have
     returned, as the case may be, the nonconverted Preferred Shares that were
     to be converted pursuant to such holder's Conversion Notice (provided that
     a holder's voiding its Conversion Notice shall not effect the Company's
     obligations to make any payments which have accrued prior to the date of
     such notice); or

                    (iv)   if the Company's inability to fully convert Preferred
     Shares is pursuant to the Exchange Cap described in Section 4(a)(y) above,
     and the issuance of additional Conversion Shares at a Conversion Price
     equal to the Market Price would not violate the rules or regulations of The
     Nasdaq Stock Market, Inc., then, subject to Section 11, require the Company
     to issue shares of Common Stock in accordance with such holder's Conversion
     Notice and pursuant to Section 2(g) above at a Conversion Price equal to
     the Market Price of the Common Stock on the date of such holder's Notice in
     Response to Inability to Convert (as defined below).

               b.   Mechanics of Fulfilling Holder's Election.  The Company
     shall immediately send via facsimile to a holder of Preferred Shares, upon
     receipt of a facsimile copy of a Conversion Notice from such holder which
     cannot be fully satisfied as described in Section

                                       15
<PAGE>
 
     4(a) above, a notice of the Company's inability to fully satisfy such
     holder's Conversion Notice (the "INABILITY TO FULLY CONVERT NOTICE"). Such
     Inability to Fully Convert Notice shall indicate (i) the reason why the
     Company is unable to fully satisfy such holder's Conversion Notice, (ii)
     the number of Preferred Shares which cannot be converted and (iii) the
     applicable Mandatory Redemption Price. Such holder shall notify the Company
     of its election pursuant to Section 4(a) above by delivering written notice
     via facsimile to the Company ("NOTICE IN RESPONSE TO INABILITY TO
     CONVERT").

               c.   Payment of Redemption Price.  If such holder shall elect to
     have its shares redeemed pursuant to Section 4(a)(i) above, the Company
     shall pay the Mandatory Redemption Price in cash to such holder within
     thirty (30) days of the Company's receipt of the holder's Notice in
     Response to Inability to Convert, provided that prior to the Company's
     receipt of the holder's Notice in Response to Inability to Convert the
     Company has not delivered a notice to such holder stating, to the
     satisfaction of the holder, that the event or condition resulting in the
     Mandatory Redemption has been cured and all Conversion Shares issuable to
     such holder can and will be delivered to the holder in accordance with the
     terms of Section 2(g). If the Company shall fail to pay the applicable
     Mandatory Redemption Price to such holder on a timely basis as described in
     this Section 4(c) (other than pursuant to a dispute as to the determination
     of the arithmetic calculation of the Redemption Price), in addition to any
     remedy such holder of Preferred Shares may have under this Statement of
     Designations and the Securities Purchase Agreement, such unpaid amount
     shall bear interest at the rate of 2.0% per month (prorated for partial
     months) until paid in full. Until the full Mandatory Redemption Price is
     paid in full to such holder, such holder may void the Mandatory Redemption
     with respect to those Preferred Shares for which the full Mandatory
     Redemption Price has not been paid and receive back such Preferred Shares.
     Notwithstanding the foregoing, if the Company fails to pay the applicable
     Mandatory Redemption Price within such thirty (30) days time period due to
     a dispute as to the determination of the arithmetic calculation of the
     Redemption Rate, such dispute shall be resolved pursuant to Section
     2(g)(iii) above with the term "Redemption Price" being substituted for the
     term "Conversion Rate".

               d.   Pro-rata Conversion and Redemption.  In the event the
     Company receives a Conversion Notice from more than one holder of Preferred
     Shares or Pari Passu Shares on the same day and the Company can convert and
     redeem some, but not all, of the Preferred Shares or Pari Passu Shares
     pursuant to this Section 4, the Company shall convert and redeem from each
     holder of Preferred Shares or Pari Passu Shares electing to have Preferred
     Shares or Pari Passu Shares converted and redeemed at such time an amount
     equal to such holder's pro-rata amount (based on the relative redemption
     amounts of all holders of Preferred Shares and Pari Passu shares) of all
     Preferred Shares and Pari Passu Shares being converted and redeemed at such
     time.

               e.   Involuntary Delisting.  In the event the Common Stock at any
     time is not designated for quotation on the Nasdaq National Market or
     listed on The New York Stock Exchange, Inc. or The American Stock Exchange,
     Inc. but such events do not constitute a Triggering Event and are not in
     connection with a Major Transaction, then in addition to any other remedies
     the holders of Preferred Shares may have at law or in equity, the Company
     shall pay to each holder of Preferred Shares an amount in cash per
     Preferred Share on each day that 

                                       16
<PAGE>
 
     the Common Stock is not so designated or listed equal to the product of the
     Liquidation Preference multiplied by 1.0%, provided that the Company shall
     not be required to make such payments for more than 24 consecutive days.
     The Company's failure to pay such amounts on each day they are due shall
     constitute a Triggering Event for purposes of Section 3.

          21.  Reissuance of Certificates.  In the event of a conversion or
     redemption pursuant to this Statement of Designations of less than all of
     the Preferred Shares represented by a particular Preferred Stock
     Certificate, the Company shall promptly cause to be issued and delivered to
     the holder of such Preferred Shares a preferred stock certificate
     representing the remaining Preferred Shares which have not been so
     converted or redeemed.

          22.  Reservation of Shares.  Subject to the Exchange Cap in Section
     11, the Company shall, so long as any of the Preferred Shares are
     outstanding, reserve and keep available out of its authorized and unissued
     Common Stock, solely for the purpose of effecting the conversion of the
     Preferred Shares, such number of shares of Common Stock as shall from time
     to time be sufficient to effect the conversion of all of the Preferred
     Shares then outstanding; provided that the number of shares of Common Stock
     so reserved shall at no time be less than 200% of the number of shares of
     Common Stock for which the Preferred Shares are at any time convertible
     (subject to the Exchange Cap if lower). The initial number of shares of
     Common Stock reserved for conversions of the Preferred Shares and each
     increase in the number of shares so reserved shall be allocated pro rata
     among the holders of the Preferred Shares based on the number of Preferred
     Shares held by each holder at the time of issuance of the Preferred Shares
     or increase in the number of reserved shares, as the case may be. In the
     event a holder shall sell or otherwise transfer any of such holder's
     Preferred Shares, each transferee shall be allocated a pro rata portion of
     the number of reserved shares of Common Stock reserved for such transferor.
     Any shares of Common Stock reserved and which remain allocated to any
     person or entity which does not hold any Preferred Shares shall be
     allocated to the remaining holders of Preferred Shares, pro rata based on
     the number of Preferred Shares then held by such holder.

          23.  Voting Rights.  Holders of Preferred Shares shall have no voting
     rights (including with respect to a Major Transaction), except as expressly
     required by law, including but not limited to the Texas Business
     Corporation Act, and as expressly provided in this Statement of
     Designations.

          24.  Liquidation, Dissolution, Winding-Up.  In the event of any
     voluntary or involuntary liquidation, dissolution or winding up of the
     Company, the holders of the Preferred Shares shall be entitled to receive
     in cash out of the assets of the Company, whether from capital or from
     earnings available for distribution to its stockholders (the "PREFERRED
     FUNDS"), after all required payments with respect to shares of the
     Company's Series A Convertible Preferred Stock which were outstanding on
     the Issuance Date, but before any amount shall be paid to the holders of
     any of the capital stock of the Company of any class junior in rank to the
     Preferred Shares in respect of the preferences as to the distributions and
     payments on the liquidation, dissolution and winding up of the Company, an
     amount per Preferred Share equal to the Stated Value plus all accrued and
     unpaid premium thereon (such sum being referred to as the "LIQUIDATION
     PREFERENCE"); provided that, if the Preferred Funds are insufficient to pay
     the

                                       17
<PAGE>
 
     full amount due to the holders of Preferred Shares and holders of the
     Company's Series D Convertible Preferred Stock and Series F Convertible
     Preferred Stock (the "Pari Passu Shares"), which  are of equal rank with
     the Preferred Shares as to payments of Preferred Funds (and redemption
     amounts), then each holder of Preferred Shares and Pari Passu Shares shall
     receive a percentage of the Preferred Funds equal to the full amount of
     Preferred Funds payable to such holder as a liquidation preference, in
     accordance with their respective Statement of Designations, Preferences and
     Rights, as a percentage of the full amount of Preferred Funds payable to
     all holders of Preferred Shares and Pari Passu Shares.  The purchase or
     redemption by the Company of stock of any class, in any manner permitted by
     law, shall not, for the purposes hereof, be regarded as a liquidation,
     dissolution or winding up of the Company.  Neither the consolidation or
     merger of the Company with or into any other Person, nor the sale or
     transfer by the Company of less than substantially all of its assets,
     shall, for the purposes hereof, be deemed to be a liquidation, dissolution
     or winding up of the Company.  No holder of Preferred Shares shall be
     entitled to receive any amounts with respect thereto upon any liquidation,
     dissolution or winding up of the Company other than the amounts provided
     for herein; provided that a holder of Preferred Shares shall be entitled to
     all amounts previously accrued with respect to amounts owed hereunder.

          25.  Preferred Rank; Participation.  (i)  All shares of Common Stock
     shall be of junior rank to all Preferred Shares and Pari Passu Shares in
     respect to the preferences as to distributions and payments upon the
     liquidation, dissolution and winding up of the Company. The rights of the
     shares of Common Stock shall be subject to the preferences and relative
     rights of the Preferred Shares and Pari Passu Shares. Without the prior
     express written consent of the holders of not less than three-fourths (3/4)
     of the then outstanding Preferred Shares and Pari Passu Shares, the Company
     shall not hereafter authorize or issue additional or other capital stock
     that is of senior or equal rank to the Preferred Shares and Pari Passu
     Shares in respect of the preferences as to distributions and payments upon
     the liquidation, dissolution and winding up of the Company. Without the
     prior express written consent of the holders of not less than three-fourths
     (3/4) of the then outstanding Preferred Shares and Pari Passu Shares, the
     Company shall not hereafter authorize or make any amendment to the
     Company's Articles of Incorporation or bylaws, or file any resolution of
     the board of directors of the Company with the Texas Secretary of State
     containing any provisions, which would adversely affect or otherwise impair
     the rights or relative priority of the holders of the Preferred Shares and
     Pari Passu Shares relative to the holders of the Common Stock or the
     holders of any other class of capital stock; provided that the foregoing
     shall not affect the Company's ability to effect a Major Transaction. In
     the event of the merger or consolidation of the Company with or into
     another corporation (other than a Major Transaction), the Preferred Shares
     and Pari Passu Shares shall maintain their relative powers, designations
     and preferences provided for herein and no merger shall result inconsistent
     therewith.

          (ii) Subject to the rights of the holders, if any, of the Parri Passu
     Shares, the holders of the Preferred Shares shall, as holders of Preferred
     Stock, be entitled to such dividends paid and distributions made to the
     holders of Common Stock to the same extent as if such holders of Preferred
     Shares had converted the Preferred Shares into Common Stock (without regard
     to any limitations on conversion herein or elsewhere) and had held such
     shares of Common Stock on the record date for such dividends and
     distributions. Payments under the preceding sentence 

                                       18
<PAGE>
 
     shall be made concurrently with the dividend or distribution to the holders
     of Common Stock; provided that the holders of the Preferred Shares shall be
     entitled to such dividends and distributions only to the extent that they
     exceed an amount per Preferred Share equal to $1,000, plus the accrued
     premium thereon.

          26.  Restriction on Redemption and Cash Dividends with respect to
     Other Capital Stock.  Until all of the Preferred Shares have been converted
     or redeemed as provided herein, except as permitted in the Rights
     Agreement, the Company shall not, directly or indirectly, redeem, or
     declare or pay any cash dividend or cash distribution on, its Common Stock
     without the prior express written consent of the holders of not less than
     two-thirds (2/3) of the then outstanding Preferred Shares.

          27.  Limitation on Number of Conversion Shares.  Notwithstanding any
     other provision herein, the Company shall not be obligated to issue any
     shares of Common Stock upon conversion of the Preferred Shares and Pari
     Passu Shares if the issuance of such shares of Common Stock would exceed
     that number of shares of Common Stock which the Company may issue upon
     Conversion of the Preferred Shares and Pari Passu Shares (the "EXCHANGE
     CAP") without breaching the Company's obligations under the rules or
     regulations of The Nasdaq Stock Market, Inc., except that such limitation
     shall not apply in the event that the Company (a) obtains the approval of
     its stockholders as required by NASD Rule 4460 (or any successor rule or
     regulation) for issuances of Common Stock in excess of such amount or (ii)
     obtains a written opinion from outside counsel to the Company that such
     approval is not required, which opinion shall be reasonably satisfactory to
     the holders of a majority of the Preferred Shares then outstanding. Until
     such approval or written opinion is obtained, no purchaser of Preferred
     Shares and Pari Passu Shares pursuant to the Purchase Agreement (the
     "PURCHASERS") shall be issued, upon conversion of Preferred Shares and Pari
     Passu Shares, shares of Common Stock in an amount greater than the product
     of (i) the Exchange Cap amount multiplied by (ii) a fraction, the numerator
     of which is the number of Preferred Shares and Pari Passu Shares issued to
     such Purchaser pursuant to the Purchase Agreement and the denominator of
     which is the aggregate amount of all the Preferred Shares and Pari Passu
     Shares issued to the Purchasers pursuant to the Purchase Agreement (the
     "CAP ALLOCATION AMOUNT"). In the event that any Purchaser shall sell or
     otherwise transfer any of such Purchaser's Preferred Shares and Pari Passu
     Shares, the transferee shall be allocated a pro rata portion of such
     Purchaser's Cap Allocation Amount. In the event that any holder of
     Preferred Shares and Pari Passu Shares shall convert all of such holder's
     Preferred Shares and Pari Passu Shares into a number of shares of Common
     Stock which, in the aggregate, is less than such holder's Cap Allocation
     Amount, then the difference between such holder's Cap Allocation Amount and
     the number of shares of Common Stock actually issued to such holder shall
     be allocated to the respective Cap Allocation Amounts of the remaining
     holders of Preferred Shares and Pari Passu Shares on a pro rata basis in
     proportion to the number of Preferred Shares then held by each such holder.

          28.  Vote to Change the Terms of Preferred Shares.  The affirmative
     vote at a meeting duly called for such purpose or the written consent
     without a meeting, of the holders of not less than two-thirds (2/3) of the
     then outstanding Preferred Shares and Pari Passu Shares, shall be required
     for any change to this Statement of Designations or the Company's
     Certificate 

                                       19
<PAGE>
 
     of Incorporation which would amend, alter, change or repeal any of the
     powers, designations, preferences and rights of the Preferred Shares.

          29.  Lost or Stolen Certificates.  Upon receipt by the Company of
     evidence satisfactory to the Company of the loss, theft, destruction or
     mutilation of any Preferred Stock Certificates representing the Preferred
     Shares, and, in the case of loss, theft or destruction, of any
     indemnification undertaking by the holder to the Company and, in the case
     of mutilation, upon surrender and cancellation of the Preferred Stock
     Certificate(s), the Company shall execute and deliver new preferred stock
     certificate(s) of like tenor and date; provided, however, the Company shall
     not be obligated to re-issue preferred stock certificates if the holder
     contemporaneously requests the Company to convert such Preferred Shares
     into Common Stock.

          30.  Remedies, Characterizations, Other Obligations, Breaches and 
     Injunctive Relief.  The remedies provided in this Statement of Designations
     shall be cumulative and in addition to all other remedies available under
     this Statement of Designations, at law or in equity (including a decree of
     specific performance and/or other injunctive relief), no remedy contained
     herein shall be deemed a waiver of compliance with the provisions giving
     rise to such remedy and nothing herein shall limit a holder's right to
     pursue actual damages for any failure by the Company to comply with the
     terms of this Statement of Designations. The Company covenants to each
     holder of Preferred Shares that there shall be no characterization
     concerning this instrument other than as expressly provided herein. Amounts
     set forth or provided for herein with respect to payments, conversion and
     the like (and the computation thereof) shall be the amounts to be received
     by the holder thereof and shall not, except as expressly provided herein,
     be subject to any other obligation of the Company (or the performance
     thereof). The Company acknowledges that a breach by it of its obligations
     hereunder will cause irreparable harm to the holders of the Preferred
     Shares and that the remedy at law for any such breach may be inadequate.
     The Company therefore agrees that, in the event of any such breach or
     threatened breach, the holders of the Preferred Shares shall be entitled,
     in addition to all other available remedies, to an injunction restraining
     any breach, without the necessity of showing economic loss and without any
     bond or other security being required.

          31.  Specific Shall Not Limit General; Construction.  No specific
     provision contained in this Statement of Designations shall limit or modify
     any more general provision contained herein. This Statement of Designations
     shall be deemed to be jointly drafted by the Company and all holders of
     Preferred Shares and shall not be construed against any person as the
     drafter hereof.

          32.  Failure or Indulgence Not Waiver.  No failure or delay on the
     part of a holder of Preferred Shares in the exercise of any power, right or
     privilege hereunder shall operate as a waiver thereof, nor shall any single

good standing under such laws.  The Company has all requisite corporate power
and authority to own, lease and operate its properties and assets, and to carry
on its business as presently conducted.  The Company is qualified to do business
as a foreign corporation in each jurisdiction in which the ownership of its
property or the nature of its business requires such qualification, except where

condition (financial or otherwise) or on the earnings, business affairs,
properties or assets of the Company, or (ii) a material and adverse affect on
the ability of the Company to perform its obligations pursuant to this Agreement
and all Exhibits annexed hereto.

Purchasers which (i) could reasonably be expected to have a material adverse
effect on the condition (financial or otherwise) or on the closing bid price of
the Common Stock, the trading volume of the Common Stock, the earnings, business
affairs, properties or assets of the Company, or (ii) could reasonably be
expected to materially and adversely affect the ability of the Company to

set forth in this Agreement. Upon their issuance and delivery pursuant to this
Agreement and their respective governing documents, the Securities will be
validly issued, fully paid and nonassessable and will be free of any liens or
encumbrances; provided, however, that the Securities are subject to restrictions
on transfer under state and/or federal securities  laws.  The issuance and sale
of the Securities will not give rise to any preemptive right or right of first
refusal or right of participation on behalf of any person that has not been
waived in writing.

not, and the consummation of the transactions contemplated hereby will not,

material liabilities or obligations other than those disclosed in the Reports,
this Agreement or those incurred in the ordinary course of the Company's
business since July 1, 1997, which individually or in the aggregate, do not or

condition (financial or otherwise) or on the closing bid price of the Common
Stock, the trading volume of the Common Stock, the earnings, business affairs,
properties or assets of the Company, or (ii) could not reasonably be expected to
materially and adversely affect the ability of the Company to perform its

jurisdiction over the Company or its properties, or the Company's listing
agreement for its Common Stock.


          3.8   Absence of Events of Default. Except as set forth in the Reports
and this Agreement, no default, as defined in the respective agreement to which
the Company is a party, and no event which, with the giving of notice or the
passage of time or both, would become a default, has occurred and is continuing
under any agreement to which the Company is a party, which (i) could reasonably
be expected to have a material adverse effect on the condition (financial or
otherwise) or on the closing bid price of the Common Stock, the trading volume
of the Common Stock, the earnings, business affairs, properties or assets of the
Company, or (ii) could reasonably be expected to materially and adversely affect
the ability of the Company to perform its obligations pursuant to this Agreement

copyright, license, trade secret or other similar right of others currently in
existence; and there is no claim being made against the Company regarding any

the earnings, business affairs, properties or assets of the Company, or (ii)
could reasonably be expected to materially and adversely affect the ability of
the Company to perform its obligations pursuant to this Agreement and all
Exhibits annexed hereto.


          3.11  Material Contracts.  Except as set forth in the Reports, the
agreements to which the Company is a party described in the Reports are valid
agreements, in full force and effect, to the extent not expired by their terms,
and the Company is not in material breach or material default under any of such
agreements.


          3.12  Litigation.  Except as disclosed in the Reports, there is no
action, proceeding or investigation pending, or threatened, against the Company
which could reasonably be expected to result, either individually or in the
aggregate, in any (i) material adverse effect on the condition (financial or

of the Common Stock, the earnings, business affairs, properties or assets of the
Company, or (ii) material and adverse effect on the ability of the Company to

          3.16  Listing.  The Company shall secure the listing of the Common
Stock issuable upon conversion of the Preferred Stock and exercise of the
Warrants upon each national securities exchange and automated quotation system
(including the Nasdaq National Market and Small Cap Market), if any, upon which
the shares of Common Stock are then listed (subject to official notice of
issuance) and shall use its best efforts to maintain , so long as any other
shares of Common Stock shall be so listed, such listing of all such shares of
Common Stock.  The Company will use its best efforts to maintain the Common
Stock's authorization for quotation on the Nasdaq National Market, Nasdaq Small
Cap, The New York Stock Exchange, or The American Stock Exchange, Inc.  The
Company has not received any notice, oral or written, regarding continued
listing (except that the Company has received a letter from Nasdaq dated July
15, 1998 stating that the closing bid price of the Common Stock was below One
Dollar for more than thirty consecutive trading days, and if, within ninety
trading days after July 15, 1998 the closing bid price of the Common Stock is
not greater than One Dollar for ten consecutive trading days the Company faces
delisting from the Nasdaq National Market) and, as long as the Preferred Stock
and Warrants are outstanding, the Company will take no action which would
materially or adversely impact their continued listing or eligibility of the
Company for such listing.  The Company does not currently meet the "net tangible
assets" Nasdaq NMS maintenance requirement, but except for the redemption
obligations resulting from the Nasdaq 20% Limitation (which will not be
applicable depending upon the Series D Convertible Price Floor or if shareholder
approval is obtained) the Company would have met such requirement immediately
after the Closing Date.


          3.17  Other Outstanding Securities/Financing Restrictions.  Except as
disclosed in the Reports, the Company has no outstanding restricted shares, or
shares of Common Stock sold under Regulation S, Regulation D or outstanding
under any other exemption from registration, which are available for sale as
unrestricted ("free trading") stock.  The Company agrees that it will only issue
the Preferred Stock to the Purchasers herein pursuant to the terms and
conditions of this Agreement and the Statement of Designations.


          3.18  Registration Alternative.  The Company covenants and agrees that
for so long as any of the Securities remain outstanding and continue to be
"restricted securities" within the meaning of Rule 144 under the Act, the
Company shall permit resales of the underlying Common Stock pursuant to Rule 144
under the Act.  The Company and the Purchasers shall provide the Transfer Agent
any and all papers necessary to complete the transfer under Rule 144, including,
but not limited to, opinions of counsel to the Transfer Agent, and the Company
shall continue to file all material required to be filed pursuant to Sections
13(a) or 15(d) of the 1934 Act.


          3.19  Capitalization.   As of July 17, 1998 the outstanding capital
stock of the Company consists of 175 shares of Series A Preferred Stock and
14,398,820 shares of Common Stock (including shares issued to Liviakis Financial
Communications).  All issued and outstanding shares of Common Stock and
preferred stock have been duly authorized and validly issued and are fully paid
and nonassessable.  The Company represents that it has a sufficient number of
authorized and reserved shares of preferred stock for the purposes of
consummating this transaction and, assuming the conversion on the Closing Date
of all shares of Preferred Stock and Warrants to be issued at such closing, a
sufficient number of authorized and reserved shares of Common Stock.

                                       10
<PAGE>
 
          3.20  Dilution.  The Company is aware and acknowledges that conversion
of the  conversion of the Preferred Stock, and/or the exercise of the Warrants,
would cause dilution to existing Shareholders and could significantly increase
the outstanding number of shares of Common Stock.


          3.21  Employee Relations.  The Company is not involved in any labor
dispute, nor, to the knowledge of the Company, is any such dispute threatened.
None of the Company's employees is a member of a union and the Company believes
that its relations with its employees are good.


          3.22  Environmental Laws.  The Company is (i) in compliance with any
and all foreign, federal, state and local laws and regulations relating to the
protection of human health and safety, the environment or hazardous or toxic
substances or wastes, pollutants or contaminants and which the Company know is
applicable to them ("Environmental Laws"), (ii) has received all permits,
licenses or other approvals required under applicable Environmental Laws to
conduct its business, and (iii) is in compliance with all terms and conditions
of any such permit, license or approval.


          3.23  Insurance.  The Company is insured by insurers of recognized
financial responsibility against such losses and risks and in such amounts as
management of the Company believes to be prudent and customary in the businesses
in which the Company is engaged.  The Company has no reason to believe that it
will not be able to renew its existing insurance coverage as and when such
coverage expires, or obtain similar coverage from similar insurers as may be
necessary to continue its business at a cost that would not materially and
adversely affect the condition, financial or otherwise, or the earnings,
business or operation, of the Company.


          3.24  Conversion and Exercise.  The Company will permit the Purchasers
to exercise their right to convert the Preferred Stock into shares of Common
Stock, with all of the rights and privileges as set forth in the Series D
Preferred Stock Statement of Designation annexed hereto as Exhibit A, the Series
E Statement of Designation annexed hereto as Exhibit  B and the Series F
Statement of Designation annexed hereto as Exhibit C.  The Company will permit
the Purchasers to exercise their right to exercise the Warrants pursuant to the
terms of the Class A Warrant, and Class B Warrant annexed hereto.


          3.25  Right of First Refusal.  In the event the Company wishes to
enter into a transaction for debt or equity financing which is convertible into
shares of Common Stock of the Company within the earlier of three months after
the closing of the Call or February 1, 1999, the Company will give each
Purchaser written notice of the terms and conditions of such offer (the "ROFR
Notice").  Each Purchaser shall have a pro rata right of first refusal to
participate in such offering.  Each Purchaser shall have three (3) business days
to reply in writing after receipt of the ROFR Notice from the Company.  Such
reply may be sent via facsimile.  In the event such written reply is not
received by the Company within such three (3) business day period, it will be
deemed a refusal by such Purchaser.  The Purchasers shall have the right to
review all final documentation regarding such placements and such documentation
shall be delivered to each Purchaser with the ROFR Notice.  The right of first
refusal shall not apply to (i) a loan from a commercial bank, (ii) any
transaction involving the issuance of the Company's securities (A) as
consideration in a merger, 

                                       11
<PAGE>
 
consolidation or other business combination, (B) in connection with any
strategic partnership or joint venture or (C) as consideration for the
acquisition of a business, product or license or other assets by the Company,
(iii) the issuance of Common Stock in a firm commitment, underwritten public
offering, (iv) the issuance of securities upon exercise or conversion of the
Company's options, warrants or other convertible securities outstanding as of
the date hereof, (v) the grant of additional options or warrants, or the
issuance of additional securities, under any Company stock option plan,
restricted stock plan, stock purchase plan or other plan or written compensation
contract for the benefit of the Company's employees, directors or consultants,
or (vi) the issuance of securities pursuant to the Rights Agreement, dated
September 15, 1997, between the Company and ChaseMellon Shareholder Services,
L.L.C. (the "Rights Agreement").


          3.26  20% Rule Limitation. The Company agrees that it shall call a
stockholders meeting on or before November 20, 1998 for the purpose of, among
other things, approving below market price issuances of Common Stock to the
Purchasers and in excess of 19.99% of the number of shares of Common Stock
outstanding as of the Closing Date as required by Section 4460(i)(1)(D) of the
Nasdaq Marketplace Rules.  In the event that the aforementioned proposal is not
ratified by the stockholders and the number of shares issuable under the
Statement of Designations and/or exercise of the Warrants would exceed 19.99% of
the number of shares of Common Stock outstanding as of the Closing Date, the
Company will seek a waiver from the Nasdaq Stock Market (or other applicable
market or exchange) to permit such issuances.


          3.27  No Brokers.  Each Purchaser represents that it has had no
dealings with any broker or finder in connection with the transactions
contemplated by this Agreement, except as described in Section 15.6.


          Section 4.   Representations and Warranties of the Company and
Purchasers.  Each of the Purchasers and the Company represent to, and agree
with, the other the following with respect to itself:

                       effectiveness of the Registration Statement, either

                       of the Company as set forth in Exhibit H annexed to this
                       Agreement, dated on the closing for the Call;

                       prior to the end of said fiscal quarter;
                (vi)   the Purchasers shall have received certification that the
                       Company has obtained shareholder approval for the
                       Company's issuance of more than twenty (20%) percent of

                       or prospects of the Company has occurred, which has not

applicable state securities laws or unless an exemption from such registration
is available.  Each of the Purchasers understands that the Securities will be
imprinted with a legend that prohibits the transfer of the Securities unless (i)
they are registered or such registration is not required, and (ii) if the
transfer is pursuant to an exemption from registration other than Rule 144 under
the Act and, if the Company shall so request in writing, an opinion of counsel
reasonably satisfactory to the Company is obtained to the effect that the
transaction is so exempt.


          Section 10.  Legend.

                         REGISTRATION RIGHTS AGREEMENT
                                        


          THIS REGISTRATION RIGHTS AGREEMENT, dated the 24th day of July, 1998,
between the entities listed on Schedules A and B (the "A Purchasers" and "B
Purchasers" or collectively, the "Holders"), issued pursuant to the Purchase
Agreement of even date herewith (the "Purchase Agreement"), and DATA RACE, INC.,
a Texas corporation having its principal place of business at 12400 Network
Blvd., San Antonio, Texas 78249 (the "Company").

          WHEREAS, simultaneously with the execution and delivery of this
Agreement, the Holders have agreed to purchase from the Company, pursuant to the
Purchase Agreement an aggregate of Four Million ($4,000,000) Dollars principal
amount of Preferred Stock and Warrants to purchase an aggregate of Eight Hundred
Forty Seven Thousand Two Hundred eighty Eight (847,288) shares of Common Stock.
The Common Stock of the Company underlying the Preferred Stock is referred to as
the "Conversion Shares", and the Common Stock of the Company underlying the
Warrants is referred to as the "Warrant Shares" (capitalized terms defined in
the Purchase Agreement and not otherwise defined herein have the meanings
specified in the Purchase Agreement); and

          WHEREAS, the Company desires to grant to the Holders the registration
rights set forth herein.

          NOW, THEREFORE, the parties hereto mutually agree as follows:

          Section 1.  Registrable Securities.  As used herein the term
Registrable Securities means the Conversion Shares, and the Warrant Shares;
provided, however, that with respect to any particular Registrable Security,
such security shall cease to be a Registrable Security when, as of the date of
determination, (i) it has been effectively registered under the Securities Act
of 1933, as amended (the Securities  Act)  and  disposed  of  pursuant  thereto,
(ii) registration under the Securities Act is no longer required for the
immediate public distribution of such security as a result of the provisions of
Rule 144, or (iii) it has ceased to be outstanding. In the event of any merger,
reorganization, consolidation, recapitalization or other change in corporate
structure affecting the Common Stock, such adjustment shall be made in the
definition of Registrable Security as is appropriate in order to prevent any
dilution or enlargement of the rights granted pursuant to this Section 1.

          Section 2.  Restrictions on Transfer.  The Holders acknowledge and
understand that prior to the registration of the Conversion Shares and Warrant
Shares as provided herein, the Securities are "restricted securities" as defined
in Rule 144 promulgated under the Securities Act.  The Holders understand that
no disposition or transfer of the Securities may be made by Holder in the
absence of (i) an opinion of counsel reasonably satisfactory to the Company that
such transfer may be made or (ii) a registration statement under the Securities
Act is then in effect with respect thereto.

          Section 3.  Registration Rights.  The Company agrees that it will
prepare and file with the Securities and Exchange Commission ("SEC"), within
thirty (30) days after receipt of 

                                       1
<PAGE>
 
written demand by a Holder ("Demand Date"), a registration statement which shall
include any and all amendments thereto (the "Registration Statement"), or in the
event more than one Registration Statement is required to be filed to include
such items as newly authorized shares, such further Registration Statement shall
be filed thirty (30) days after the issuance of such newly authorized shares or
other event, as the case may be. In the event that such Registration Statement
is not effective within ninety (90) days after the Demand Date, then Section
3(e) liquidated damages shall apply, at the sole expense of the Company (except
as provided in Section 3(c) hereof), in respect of all holders of Registrable
Securities, so as to permit resale of the Registrable Securities under the
Securities Act, provided, the Company shall not be obligated to take any action
to effect any such registration, qualification or compliance pursuant to this
Section 3(a) in any jurisdiction in which the Company would be required to
qualify as a dealer in securities, under the securities or blue sky laws of such
jurisdiction.

          The Company agrees that it will cause the Registration Statement to
become effective within ninety (90) days after the Demand Date.  The number of
Registrable Securities to be registered shall be two hundred (200%) percent of
the number of shares that would be required if all of the Registrable Securities
were converted in accordance with the Statement of Designation, on a date which
is five (5) business days prior to the filing of the Registration Statement, or
such lower number of shares as may be issuable in accordance with Nasdaq
regulations.

          (b)  The Company will maintain the Registration Statement or post-
effective amendment filed under this Section 3 hereof current under the
Securities Act until the earlier of (i) the date that all of the Registrable
Securities have been sold pursuant to the Registration Statement, (ii) the date
that the Registrable Securities may be sold under the provisions of Rule 144 or
(iii) two years three months after the effective date of the Registration
Statement.

          (c)  All fees, disbursements and out-of-pocket expenses and costs
incurred by the Company in connection with the preparation and filing of the
Registration Statement under Section 3(a) and in complying with applicable
securities and Blue Sky laws (including, without limitation, all attorneys'
fees) shall be borne by the Company. The Holders shall bear the cost of
underwriting discounts and commissions, if any, applicable to the Registrable
Securities being registered and all of other the fees and expenses of such
registration, including of its counsel and such other expenses as are necessary
to qualify the sale of Securities in compliance with any state Blue Sky laws.
The Company shall qualify any of the securities for sale in such states as such
Holders reasonably designate and shall furnish indemnification in the manner
provided in Section 9 hereof. However, the Company shall not be required to
qualify in any state which will require an escrow or other restriction relating
to the Company and/or the sellers. The Company at its expense will supply the
Holders with copies of such Registration Statement and the prospectus or
offering circular included therein and other related documents in such
quantities as may be reasonably requested by the Holders.

          (d)  The Company shall not be required by this Section 3 to include
Holder's Registrable Securities in the Amended Registration Statement which is
to be filed if, in the opinion of counsel for both the Holders and the Company
(or, should they not agree, in the opinion of another counsel experienced in
securities law matters acceptable to counsel for the Holder and the Company) the
proposed offering or other transfer as to which such registration is requested
is 

                                       2
<PAGE>
 
exempt from applicable federal and state securities laws and would result in all
purchasers or transferees obtaining securities which are not restricted
securities, as defined in Rule 144 under the Securities Act.

          (e)  In the event the Registration Statement to be filed by the
Company pursuant to Section 3(a) above is not filed by the Company by the
thirtieth (30th) day after the Demand Date, or if the Registration Statement is
not declared effective by the SEC by the ninetieth (90th) day after the Demand
Date (the Effective Date), then the Company will pay, in cash, to the Holders
who made such a demand, on a pro-rata basis by wire transfer, as liquidated
damages for such failure and not as a penalty, two (2%) percent of the principal
amount of the outstanding Preferred Stock and Warrants that have been exercised
by the Holder, each month thereafter until the Registration Statement has been
filed and/or declared effective. The liquidated damages shall be payable within
seven (7) calendar days of written demand by the Holder.

          If the Company does not remit the damages to the Holder as set forth
above, the Company will pay the to the Holders the reasonable costs of
collection, including attorneys fees, in addition to the liquidated damages.
Such payment shall be made to the Holders in cash immediately if the
registration of the Securities are not effected; provided, however, that the
payment of such liquidated damages shall not relieve the Company from its
obligations to register the Securities pursuant to this Section.  The
registration of the Securities pursuant to this provision shall not affect or
limit Holder's other rights or remedies as set forth in this Agreement.

          (f)  No provision contained herein shall preclude the Company from
selling securities pursuant to any registration statement in which it is
required to include Registrable Securities pursuant to this Section 3.

          (g)  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 Holders based on the
number of Registrable Securities held by each Holder at the time of such
establishment or increase, as the case may be.  In the event a Holder shall sell
or otherwise transfer any of such holder'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 or entity which does not hold any
Registrable Securities shall be allocated to the remaining holders, pro rata
based on the number of Registrable Securities then held by such Holders.  For
the purposes hereof, the number of Registrable Securities held by any Holder
shall be determined as if all Preferred Stock and Warrants then outstanding were
then converted into or exercised for Registrable Securities (whether or not such
securities are then convertible or exercisable).

          Section 4.  Cooperation with Company.  Holders will cooperate with the
Company in all respects in connection with this Agreement, including, timely
supplying all information reasonably requested by the Company and executing and
returning all documents reasonably requested in connection with the registration
and sale of the Registrable Securities.

          Section 5.  Registration Procedures.  Whenever the Company is required
by the 

                                       3
<PAGE>
 
provisions of this Agreement to effect the registration of any of the
Registrable Securities under the Securities Act, the Company shall (except as
otherwise provided in this Agreement), as expeditiously as possible:

          (a)  prepare and file with the Commission such amendments and
supplements to such registration statement and the Prospectus used in connection
therewith as may be necessary to keep such registration statement effective as
per Section 3(b) herein and to comply with the provisions of the Securities Act
with respect to the sale or other disposition of all securities covered by such
registration statement when the Holder or Holders of such securities shall
desire to sell or otherwise dispose of the same (including prospectus
supplements with respect to the sales of securities from time to time in
connection with a registration statement pursuant to Rule 415 under the
Securities Act);

          (b)  furnish to each Holder such numbers of copies of a summary
prospectus or other prospectus, including a preliminary prospectus or any
amendment or supplement to any prospectus, in conformity with the requirements
of the Securities Act, and such other documents, as such Holder may reasonably
request in order to facilitate the public sale or other disposition of the
securities owned by such Holder;

          (c)  use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or blue sky
laws of such jurisdictions as the Holder, shall reasonably request, and do any
and all other acts and things which may be necessary or advisable to enable each
Holder to consummate the public sale or other disposition in such jurisdiction
of the securities owned by such Holder, except that the Company shall not for
any such purpose be required to qualify to do business as a foreign corporation
in any jurisdiction wherein it is not so qualified or to file therein any
general consent to service of process;

          (d)  list such securities on the Nasdaq National Market System or any
securities exchange on which the Common Stock is then listed, if the listing of
such securities is then permitted under the rules of such system or exchange;

          (e)  enter into and perform its obligations under an underwriting
agreement, if the offering is an underwritten offering, in usual and customary
form, with the managing underwriter or underwriters of such underwritten
offering;

          (f)  notify each Holder of Registrable Securities covered by such
registration statement, at any time when a prospectus relating thereto covered
by such registration statement is required to be delivered under the Securities
Act, of the happening of any event of which it has knowledge as a result of
which the prospectus included in such registration statement, as then in effect,
includes an untrue statement of a material fact or omits to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading in the light of the circumstances then existing.

          Section 6.  Assignment.  The rights granted the Holders under this
Agreement shall not be assigned without the written consent of the Company,
which consent shall not be unnecessarily withheld.  In the event of a transfer
of the rights granted under this Agreement, the 

                                       4
<PAGE>
 
Holders agree that the Company may require that the transferee comply with
reasonable conditions as determined in the discretion of the Company. This
Agreement is binding upon and inures to the benefit of the parties hereto and
their respective heirs, successors and permitted assigns.

          Section 7.  Termination of Registration Rights.  The rights granted
pursuant to this Agreement shall terminate as to each Holder (and permitted
transferees or assignees) upon the occurrence of any of the following:

          (a)  all of that particular Holder's securities subject to this
Agreement have been registered;

          (b)  such Holder's securities subject to this Agreement may be sold
without such registration pursuant to Rule 144 promulgated by the SEC pursuant
to the Securities Act; or

          (c)  all of such Holder's securities subject to this Agreement can be
sold pursuant to Rule 144(k).

          Section 8.  Indemnification.

          (a)  The Company and all key operating subsidiaries agree to indemnify
and hold harmless the Holders and each officer, director of the Holders, or
person, if any, who controls each Holder within the meaning of the Securities
Act (Distributing Holders) against any losses, claims, damages or liabilities,
joint or several (which shall, for all purposes of this Agreement, include, but
not be limited to, all costs of defense and investigation and all attorneys'
fees), to which the Distributing Holders may become subject, under the
Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
the Registration Statement, or any related preliminary prospectus, final
prospectus, offering circular, notification or amendment or supplement thereto,
or arise out of or are based upon the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading; provided, however, that neither the Company
nor all key operating subsidiaries will be liable in any such case to the extent
that any such loss, claim, damage or liability arises out of or is based upon an
untrue statement or alleged untrue statement or omission or alleged omission
made in the Registration Statement, preliminary prospectus, final prospectus,
offering circular, notification or amendment, or supplement thereto in reliance
upon, and in conformity with, written information furnished to the Company by
the Distributing Holders, specifically for use in the preparation thereof. This
Section shall not inure to the benefit of any Distributing Holder with respect
to any person asserting such loss, claim, damage or liability who purchased the
Registrable Securities which are the subject thereof if the Distributing Holder
failed to send or give (in violation of the Securities Act or the rules and
regulations promulgated thereunder) a copy of the prospectus contained in the
Registration Statement to such person at or prior to the written confirmation to
such person of the sale of such Registrable Securities, where the Distributing
Holder was obligated to do so under the Securities Act or the rules and
regulations promulgated hereunder. This indemnity agreement will be in addition
to any liability which the Company may otherwise have.

          (b)  Each Distributing Holder agrees that it will indemnify and hold
harmless the

                                       5
<PAGE>
 
Company and each officer, director of the Company, or person, if any, who
controls the Company and all key operating subsidiaries within the meaning of
the Securities Act, against any losses, claims, damages or liabilities (which
shall, for all purposes of this Agreement, include, but not be limited to, all
costs of defense and investigation and all attorneys' fees) to which the Company
and all key operating subsidiaries or any such officer, director or controlling
person may become subject under the Securities Act or otherwise, insofar as such
losses claims, damages or liabilities (or actions in respect thereof); arise out
of or are based upon any untrue statement or alleged untrue statement of any
material fact contained in the Registration Statement prepared by the Company
and all key operating subsidiaries, or any related preliminary prospectus, final
prospectus, offering circular, notification or amendment or supplement thereto,
or arise out of or are based upon the omission or the alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, but in each case only to the extent that such
untrue statement or alleged untrue statement or omission or alleged omission was
made in such Registration Statement, preliminary prospectus, final prospectus,
offering circular, notification or amendment or supplement thereto in reliance
upon, and in conformity with, written information furnished to the Company and
all key operating subsidiaries by such Distributing Holder, specifically for use
in the preparation thereof. This indemnity agreement will be in addition to any
liability which the distributing Holders may otherwise have.

          (c)  Promptly after receipt by an indemnified party under this Section
of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section, notify the indemnifying party of the commencement thereof; but the
omission so to notify the indemnifying party will not relieve the indemnifying
party from any liability which it may have to any indemnified party otherwise
than as to the particular item as to which indemnification is then being sought
solely pursuant to this Section, except where such omission materially
prejudices the indemnifying party's rights. In case any such action is brought
against any indemnified party, and it notifies the indemnifying party of the
commencement thereof, the indemnifying party will be entitled to participate in,
and, to the extent that it may wish, jointly with any other indemnifying party
similarly notified, assume the defense thereof, subject to the provisions herein
stated and after notice from the indemnifying party to such indemnified party of
its election so to assume the defense thereof, the indemnifying party will not
be liable to such indemnified party under this Section for any legal or other
expenses subsequently incurred by such indemnified party in connection with the
defense thereof other than reasonable costs of investigation, unless the
indemnifying party shall not pursue the action to its final conclusion. The
indemnified party shall have the right to employ separate counsel in any such
action and to participate in the defense thereof, but the fees and expenses of
such counsel shall not be at the expense of the indemnifying party if the
indemnifying party has assumed the defense of the action with counsel reasonably
satisfactory to the indemnified party; provided that the fees and expenses of
such counsel shall be at the expense of the indemnifying party if (i) the
employment of such counsel has been specifically authorized in writing by the
indemnifying party, or (ii) the named parties to any such action (including any
impleaded parties) include both the indemnified party and the indemnifying party
and the indemnified party shall have been reasonably advised by such counsel
that there may be one or more legal defenses available to the indemnifying party
different from or in conflict with any legal defenses which may be available to
the indemnified party (in which case the indemnifying party shall not have the
right to assume the defense of such action on behalf of the indemnified party,
it being understood, however, that the indemnifying party shall, in

                                       6
<PAGE>
 
connection with any one such action or separate but substantially similar or
related actions in the same jurisdiction arising out of the same general
allegations or circumstances, be liable only for the reasonable fees and
expenses of one separate firm of attorneys for all indemnified parties, which
firm shall be designated in writing by the indemnified parties holding a
majority of the Registrable Securities). No settlement of any action against an
indemnified party shall be made without the prior written consent of the
indemnified party, which consent shall not be unreasonably withheld.

          Section 9.  Contribution.  In order to provide for just and equitable
contribution under the Securities Act in any case in which (i) the Distributing
Holders, or the Company or all key operating subsidiaries, makes a claim for
indemnification, but is judicially determined (by the entry of a final judgment
or decree by a court of competent jurisdiction and the expiration of time to
appeal or the denial of the last right of appeal) that such indemnification may
not be enforced in such case notwithstanding the fact that the express
provisions of this Agreement provide for indemnification in such case, or (ii)
contribution under the Securities Act may be required on the part of any
Distributing Holder, or the Company or all key operating subsidiaries, then the
Company and all key operating subsidiaries and the applicable Distributing
Holder shall contribute to the aggregate losses, claims, damages or liabilities
to which they may be subject (which shall, for all purposes of this Agreement,
include, but not be limited to, all costs of defense and investigation and all
attorneys' fees), in either such case (after contribution from others) on the
basis of relative fault as well as any other relevant equitable considerations.
The relative fault shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company and all key operating subsidiaries on the one hand or
the applicable Distributing Holder, on the other hand, and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission. The Company and all key operating subsidiaries and
the Distributing Holders agree that it would not be just and equitable if
contribution pursuant to this Section were determined by pro rata allocation or
by any other method of allocation which does not take account of the equitable
considerations referred to in this Section. The amount paid or payable by an
indemnified party as a result of the losses, claims, damages or liabilities (or
actions in respect thereof) referred to above in this Section shall be deemed to
include any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending any such action or claim. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

     Section 10.  "Piggy-Back" Registration. The Holders of this Registration
Rights Agreement shall have the right to include all Registrable Securities as
part of any registration of securities filed by the Company (other than that
required to be filed pursuant to the terms herein, and in connection with a
transaction contemplated by Rule 145(a) promulgated under the Act or pursuant to
Form S-8) and must be notified in writing of such filing; provided, however,
that the Holders agree it shall not have any piggy-back registration rights
pursuant to this Agreement if the Registrable Securities may be sold in the
United States pursuant to the provisions of Rule 144. Holders shall have five
(5) business days to notify the Company in writing as to whether the Company is
to include Holders or not include Holders as part of the registration; provided,
however, that if any registration pursuant to this Section shall be
underwritten, in whole or in part, the Company may require that the Registrable
Securities requested for inclusion pursuant to this Section

                                       7
<PAGE>
 
be included in the underwriting on the same terms and conditions as the
securities otherwise being sold through the underwriters and the Holders agree
to enter into an underwriting agreement in customary form reasonably acceptable
to the Holders. If in the good faith judgment of the underwriter evidenced in
writing of such offering only a limited number of Registrable Securities should
be included in such offering, or no such shares should be included, the Holders,
and all other selling stockholders, shall be limited to registering such
proportion of their respective shares as shall equal the proportion that the
number of shares of selling stockholders permitted to be registered by the
underwriter in such offering bears to the total number of all shares then held
by all selling stockholders desiring to participate in such offering. Those
Registrable Securities which are excluded from an underwritten offering pursuant
to the foregoing provisions of this Section (and all other Registrable
Securities held by the selling stockholders) shall be withheld from the market
by the Holders thereof for a period, not to exceed ninety (90) days, which the
underwriter may reasonably determine is necessary in order to effect such
underwritten offering. The Company shall have the right to terminate or withdraw
any registration initiated by it under this Agreement prior to the effectiveness
of such registration whether or not any Holder elected to include securities in
such registration. All registration expenses incurred by the Company in
complying with this Agreement shall be paid by the Company, exclusive of
underwriting discounts, commissions and legal fees and expenses for counsel to
the Holders.

          Section 11.  Notices.   Any notice pursuant to this Agreement by the
Company or by the Holder shall be in writing and shall be deemed to have been
duly given if delivered by (i) hand, (ii) by facsimile and followed by mail
delivery or (iii) if mailed by certified mail, return receipt requested, postage
prepaid, addressed  as follows:

          (a)  If to the Holders, to its, his or her address set forth on
Schedule A and Schedule B attached to this Agreement.

          (b)  If to the Company, at the address set forth herein, or to such
other address as any such party may designate by notice to the other party.
Notices shall be deemed given at the time they are delivered personally or five
(5) days after they are mailed in the manner set forth above. If notice is
delivered by facsimile to the Company and followed by mail, delivery shall be
deemed given two (2) days after such facsimile is sent.

          Section 12.  Counterparts. This Agreement may be executed in
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

          Section 13.  Headings.  The headings in this Agreement are for
reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement.

          Section 14.  Governing Law, Venue. This Agreement will be construed
and enforced in accordance with and governed by the laws of the State of New
York, except for matters arising under the Securities Act, without reference to
principles of conflicts of law.  Each of the parties consents to the
jurisdiction of the federal courts whose districts encompass any part of the
State of New York in connection with any dispute arising under this Agreement
and hereby waives, to the maximum extent permitted by law, any objection,
including any objection based on forum non 

                                       8
<PAGE>
 
conveniens, to the bringing of any such proceeding in such jurisdictions. Each
party hereby agrees that if another party to this Agreement obtains a judgment
against it in such a proceeding, the party which obtained such judgment may
enforce same by summary judgment in the courts of any state or country having
jurisdiction over the party against whom such judgment was obtained, and each
party hereby waives any defenses available to it under local law and agrees to
the enforcement of such a judgment. Each party to this Agreement irrevocably
consents to the service of process in any such proceeding by the mailing of
copies thereof by registered or certified mail, postage prepaid, to such party
at its address set forth herein. Nothing herein shall affect the right of any
party to serve process in any other manner permitted by law.

          Section 14.  Severability/Defined Terms.  If any provision of this
Agreement shall for any reason be held invalid or unenforceable, such invalidity
or unenforceability shall not affect any other provision hereof and this
Agreement shall be construed as if such invalid or unenforceable provision had
never been contained herein.  Terms not otherwise defined herein shall be
defined in accordance with the Purchase Agreement.

                                       9

          IN WITNESS WHEREOF, the parties hereto have caused this Registration
Rights Agreement to be duly executed, on the day and year first above written.

THESE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT").  SUCH SECURITIES MAY
NOT BE OFFERED OR SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN
EXEMPTION THEREFROM UNDER SAID ACT.

                                FORM OF CLASS A
                            STOCK PURCHASE WARRANT
                  To Purchase _____ Shares of Common Stock of

                                DATA RACE, INC.


          THIS CERTIFIES that, for value received, _________ (the "Investor"),
is entitled, upon the terms and subject to the conditions hereinafter set forth,
at any time upon the earlier of (i) ninety-one (91) days after the date hereof,
or (ii) the Effective Date of the Registration Statement which shall include the
Warrant Shares, and on or prior to ___________, which is two (2) years after the
date of issuance (the "Termination Date"), but not thereafter, to subscribe for
and purchase from DATA RACE, INC., a Texas corporation (the "Company"),
__________ _____________ (_________) shares of Common Stock (the "Warrant
Shares"). The purchase price of one share of Common Stock (the "Exercise Price")
under this Warrant shall be equal to [the lesser of (i) one hundred twenty
percent (120%) of the average of the three lowest closing bid prices of the
Common Stock during the twenty-two (22) trading days immediately preceding the
date this Warrant was issued, or (ii) US $0.80.] The Exercise Price and the
number of shares for which the Warrant is exercisable shall be subject to
adjustment as provided herein. This Warrant is being issued in connection with
the Purchase Agreement dated on or about July     , 1998 for preferred stock and
warrants in the amount of Four Million ($4,000,000) Dollars (the "Agreement")
between the Company and Investor and certain other investors and is subject to
its terms. In the event of any conflict between the terms of this Warrant and
the Agreement, the Agreement shall control.

          1.   Title of Warrant.  Prior to the expiration hereof and subject to
compliance with applicable laws, this Warrant and all rights hereunder are
transferable, in whole or in part, at the office or agency of the Company by the
holder hereof in person or by duly authorized attorney, upon surrender of this
Warrant together with the Assignment Form annexed hereto properly endorsed.

          2.   Authorization of Shares.  The Company covenants that all shares
of Common Stock which may be issued upon the exercise of rights represented by
this Warrant will, upon exercise of the rights represented by this Warrant, be
duly authorized, validly issued, fully paid and nonassessable and free from all
taxes, liens and charges in respect of the issue thereof (other than taxes in
respect of any transfer occurring contemporaneously with such issue).

          3.   Exercise of Warrant.  Exercise of the purchase rights represented
by this Warrant may be made, in whole or in part, upon the earlier of (i) ninety
one (91) days after the date hereof, or (ii) the Effective Date of the
Registration Statement which shall include the Warrant Shares, and before the
close of business on the Termination Date by the surrender of this Warrant 

                                       1
<PAGE>
 
and the Notice of Exercise annexed hereto duly executed, at the office of the
Company located at 12400 Network Blvd., San Antonio, Texas 78249, and upon
payment of the Exercise Price of the shares thereby purchased; whereupon the
holder of this Warrant shall be entitled to receive a certificate for the number
of shares of Common Stock so purchased. Certificates for shares purchased
hereunder shall be delivered by the Company, or the Company shall have
instructed its Transfer Agent to deliver to the holder hereof within five
business days after the date on which this Warrant shall have been exercised as
aforesaid. Payment of the Exercise Price of the shares may be by certified check
or cashier's check or by wire transfer to an account designated by the Company
in an amount equal to the Exercise Price multiplied by the number of shares
being purchased.

          4.   No Fractional Shares or Scrip.  No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of this
Warrant.

          5.   Charges, Taxes and Expenses.  Issuance of certificates for shares
of Common Stock upon the exercise of this Warrant shall be made without charge
to the holder hereof for any issue or transfer tax or other incidental expense
in respect of the issuance of such certificate, all of which taxes and expenses
shall be paid by the Company, and such certificates shall be issued in the name
of the holder of this Warrant or in such name or names as may be directed by the
holder of this Warrant; provided, however, that in the event certificates for
shares of Common Stock are to be issued in a name other than the name of the
holder of this Warrant, this Warrant when surrendered for exercise shall be
accompanied by the Assignment Form attached hereto duly executed by the holder
hereof; and provided further, that upon any transfer involved in the issuance or
delivery of any certificates for shares of Common Stock, the Company may
require, as a condition thereto, the payment of a sum sufficient to reimburse it
for any transfer tax incidental thereto.

          6.   Restrictions on Transfer.

          (a)  This Warrant has been issued subject to investment
representations of the original Holder hereof and may be transferred or
exchanged only in compliance with the Securities Act and applicable state
securities laws and in compliance with the restrictions on transfer provided in
the Agreement. The transferee shall be bound, as the original Holder by the same
representations and terms described herein and under the Agreement. This Warrant
and any Warrant Shares may not be sold, transferred, pledged, hypothecated or
otherwise disposed of except as follows: (i) to a person who, in the opinion of
counsel to the Company, is a person to whom this Warrant or the Warrant Shares
may legally be transferred without registration and without the delivery of a
current prospectus under the Act with respect thereto, and then only against
receipt of an agreement of such person to comply with the provisions of this
Section 6(a) with respect to any resale or other disposition of such securities;
or (ii) to any person upon delivery of a prospectus then meeting the
requirements of the Act relating to such securities and the offering thereof for
such sale or disposition, and thereafter to all successive assignees.

          (b)  Unless the Warrant Shares have been registered under the Act, or
exempt from registration, upon exercise of any of the Warrant and the issuance
of any of the Warrant Shares, all certificates representing Warrant Shares shall
bear on the face thereof substantially the following legend:

                                       2
<PAGE>
 
          "THESE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"). SUCH
     SECURITIES MAY NOT BE OFFERED OR SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH
     REGISTRATION OR AN EXEMPTION THEREFROM UNDER SAID ACT."


          7.   Closing of Books.  The Company will at no time close its
shareholder books or records in any manner which interferes with the timely
exercise of this Warrant.

          8.   No Rights as Shareholder until Exercise.  This Warrant does not
entitle the holder hereof to any voting rights or other rights as a shareholder
of the Company prior to the exercise thereof. If, however, at the time of the
surrender of this Warrant and purchase the holder hereof shall be entitled to
exercise this Warrant, the shares so purchased shall be and be deemed to be
issued to such holder as the record owner of such shares as of the close of
business on the date on which this Warrant shall have been exercised.
 
          9.   Loss, Theft, Destruction or Mutilation of Warrant.  The Company
represents and warrants that upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of any Warrant
or stock certificate, and in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to it, and upon reimbursement to the Company of
all reasonable expenses incidental thereto, and upon surrender and cancellation
of such Warrant or stock certificate, if mutilated, the Company will make and
deliver a new Warrant or stock certificate of like tenor and dated as of such
cancellation, in lieu of this Warrant or stock certificate.

          10.  Saturdays, Sundays, Holidays, etc.  If the last or appointed day
for the taking of any action or the expiration of any right required or granted
herein shall be a Saturday, Sunday or a legal holiday, then such action may be
taken or such right may be exercised on the next succeeding day not a legal
holiday.

          11.  Effect of Certain Events.  In case the Company shall at any time
prior to the Termination Date effect a Sale or Merger Transaction, the holder of
this Warrant shall have the right thereafter to purchase, by exercise of this
Warrant and payment of the aggregate Exercise Price in effect immediately prior
to such action, the kind and amount of shares and other securities and property
which it would have owned or have been entitled to receive after the happening
of such transaction had this Warrant been exercised immediately prior thereto.
The holder hereof shall be given at least ten days notice prior to the effective
date of such transaction and shall have the right to exercise this Warrant
immediately prior to the transaction, whether or not this Warrant is then
exercisable, and to participate in such transaction on the same basis as other
holders of Common Stock. In the event this Warrant is being exercised under such
circumstances immediately prior to a Sale or Merger Transaction, then the
Warrant may be exercised on a cashless basis in which, in lieu of paying the
Exercise Price in cash, the holder may surrender the right to receive upon
exercise that number of shares of Common Stock determined by multiplying the
number of Warrant Shares to which the holder would otherwise be entitled by a
fraction, the numerator of which shall be the amount by which the then current
market price per share of Common Stock exceeds the Exercise

                                       3
<PAGE>
 
Price, and the denominator of which will be the then current market price per
share of Common Stock.

          12.  Adjustments of Exercise Price and Number of Warrant Shares.  The
number and kind of securities purchasable upon the exercise of this Warrant and
the Exercise Price shall be subject to adjustment from time to time upon the
happening of any of the following.

          In case the Company shall (i) declare or pay a dividend in shares of
Common Stock or make a distribution in shares of Common Stock to holders of its
outstanding Common Stock, (ii) subdivide its outstanding shares of Common Stock,
(iii) combine its outstanding shares of Common Stock into a smaller number of
shares of Common Stock or (iv) issue any shares of its capital stock in a
reclassification of the Common Stock, the number of Warrant Shares purchasable
upon exercise of this Warrant immediately prior thereto shall be adjusted so
that the holder of this Warrant shall be entitled to receive the kind and number
of Warrant Shares or other securities of the Company which he would have owned
or have been entitled to receive had such Warrant been exercised in advance
thereof. An adjustment made pursuant to this paragraph shall become effective
immediately after the effective date of such event retroactive to the record
date, if any, for such event.

          13.  Voluntary Adjustment by the Company.  The Company may at its
discretion, at any time during the term of this Warrant, reduce the then current
Exercise Price to any amount and for any period of time deemed appropriate by
the Board of Directors of the Company.

          14.  Notice of Adjustment.  Whenever the number of Warrant Shares or
number or kind of securities or other property purchasable upon the exercise of
this Warrant or the Exercise Price is adjusted, as herein provided, the Company
shall promptly mail by registered or certified mail, return receipt requested,
to the holder of this Warrant notice of such adjustment or adjustments setting
forth the number of Warrant Shares (and other securities or property)
purchasable upon the exercise of this Warrant and the Exercise Price of such
Warrant Shares after such adjustment, setting forth a brief statement of the
facts requiring such adjustment and setting forth computation by which such
adjustment was made. Such notice, in absence of manifest error, shall be
conclusive evidence of the correctness of such adjustment.

          15.  Purchase Rights.  If at any time after the date hereof, the
Company grants, issues, sells or distributes any options, convertible securities
or rights to purchase stock, warrants, securities or other property pro rate to
the record holders 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 full exercise of this Warrant (without taking into account any limitations
or restrictions on the timing or amount of exercise) immediately before the date
on which a record is taken for the grant, issuance, sale or distribution 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 or
other distribution of such Purchase Rights.

          16.  Authorized Shares.  The Company covenants that during the period
the Warrant is outstanding, it will reserve from its authorized and unissued
Common Stock a sufficient 

                                       4
<PAGE>
 
number of shares to provide for the issuance of Common Stock upon the exercise
of any purchase rights under this Warrant. The Company further covenants that
its issuance of this Warrant shall constitute full authority to its officers who
are charged with the duty of executing stock certificates to execute and issue
the necessary certificates for shares of the Company's Common Stock upon the
exercise of the purchase rights under this Warrant. The Company will take all
such reasonable action as may be necessary to assure that such shares of Common
Stock may be issued as provided herein without violation of any applicable law
or regulation, or of any requirements of the Nasdaq National Market or any
domestic securities exchange upon which the Common Stock may be listed.

          17.  Limitation on Number of Warrant Shares.  Notwithstanding any
other provision herein, the Company shall not be obligated to issue any Warrant
Shares upon exercise of this Warrant or any other warrants issued pursuant to
the Agreement or conversion of any shares of Preferred Stock issued pursuant to
the Agreement ("Preferred Stock") 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 or any other warrants issued pursuant to the
Agreement or conversion of any shares of Preferred Stock issued pursuant to the
Agreement (the "Exchange Cap") without breaching the Company's obligations under
the rules or regulations of The Nasdaq Stock Market, Inc., except that such
limitation shall not apply in the event that the Company (a) obtains the
approval of its stockholders as required by NASD Rule 4460 (or any successor
rule or regulation) for issuances of Common Stock in excess of such amount, or
(ii) obtains a written opinion from outside counsel to the Company that such
approval is not required, which opinion shall be reasonably satisfactory to the
holders of Warrants representing a majority of the Warrant Shares then issuable
upon exercise of outstanding 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 to the extent the number of shares of Common Stock
issued to such holder upon conversion of Preferred Stock plus the number of
Warrant Shares issued upon exercise of this Warrant would be greater than such
holder's Cap Allocation Amount (as defined in the applicable Statement of
Designations for such Preferred Stock). In the event the Company is prohibited
from issuing Warrant Shares as a result of the operation of this Section, the
Company shall redeem for cash those Warrant Shares which can not be issued at a
price equal to amount by which the then-current market price exceeds the
Exercise Price of such Warrant Shares as of the date of the attempted exercise.

          18.  Miscellaneous.

          (a)  Issue Date; Jurisdiction.  The provisions of this Warrant shall
be construed and shall be given effect in all respects as if it had been issued
and delivered by the Company on the date hereof. This Warrant shall be binding
upon any successors or assigns of the Company. This Warrant shall constitute a
contract under the laws and jurisdictions of New York and for all purposes shall
be construed in accordance with and governed by the laws of said state without
regard to its conflict of law, principles or rules.

          (b)  Restrictions.  The holder hereof acknowledges that the Common
Stock acquired upon the exercise of this Warrant, if not registered, may have
restrictions upon its resale imposed by state and federal securities laws.

                                       5
<PAGE>
 
          (c)  Modification and Waiver.  This Warrant and any provisions hereof
may be changed, waived, discharged or terminated only by an instrument in
writing signed by the party against which enforcement of the same is sought.

          (d)  Notices.  Any notice, request or other document required or
permitted to be given or delivered to the holders hereof of the Company shall be
delivered or shall be sent by certified or registered mail, postage prepaid, to
each such holder at its address as shown on the books of the Company or to the
Company at the address set forth in the Agreement.

THESE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT").  SUCH SECURITIES MAY
NOT BE OFFERED OR SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN
EXEMPTION THEREFROM UNDER SAID ACT.

                                FORM OF CLASS B
                            STOCK PURCHASE WARRANT
                  To Purchase _____ Shares of Common Stock of

                                DATA RACE, INC.


     THIS CERTIFIES that, for value received,  _________ (the "Investor"), is
entitled, upon the terms and subject to the conditions hereinafter set forth, at
any time one year after the date hereof, and on or prior to ___________, which
is two (2) years after the date of issuance (the "Termination Date") but not
thereafter, to subscribe for and purchase from DATA RACE, INC., a Texas
corporation (the "Company"), ____________________ (_________) shares of Common
Stock (the "Warrant Shares").  The purchase price of one share of Common Stock
(the "Exercise Price") under this Warrant shall be US $0.80.  The Exercise Price
and the number of shares for which the Warrant is exercisable shall be subject
to adjustment as provided herein.  This Warrant is being issued in connection
with the Purchase Agreement dated on or about July 24, 1998 for preferred stock
and warrants in the amount of Four Million ($4,000,000) Dollars (the
"Agreement") between the Company and Investor and certain other investors and is
subject to its terms.  In the event of any conflict between the terms of this
Warrant and the Agreement, the Agreement shall control.

     1.   Title of Warrant.  Prior to the expiration hereof and subject to
compliance with applicable laws, this Warrant and all rights hereunder are
transferable, in whole or in part, at the office or agency of the Company by the
holder hereof in person or by duly authorized attorney, upon surrender of this
Warrant together with the Assignment Form annexed hereto properly endorsed.

     2.   Authorization of Shares.  The Company covenants that all shares of
Common Stock which may be issued upon the exercise of rights represented by this
Warrant will, upon exercise of the rights represented by this Warrant, be duly
authorized, validly issued, fully paid and nonassessable and free from all
taxes, liens and charges in respect of the issue thereof (other than taxes in
respect of any transfer occurring contemporaneously with such issue).

     3.   Exercise of Warrant.  Exercise of the purchase rights represented by
this Warrant may be made, in whole or in part, upon the earlier of one year
after the date hereof, and before the close of business on the Termination Date
by the surrender of this Warrant and the Notice of Exercise annexed hereto duly
executed, at the office of the Company located at 12400 Network Blvd., San
Antonio, Texas 78249, and upon payment of the Exercise Price of the shares
thereby purchased; whereupon the holder of this Warrant shall be entitled to
receive a certificate for the number of shares of Common Stock so purchased.
Certificates for shares purchased hereunder shall

                                       1
<PAGE>
 
be delivered by the Company, or the Company shall have instructed its Transfer
Agent to deliver to the holder hereof within five business days after the date
on which this Warrant shall have been exercised as aforesaid. Payment of the
Exercise Price of the shares may be by certified check or cashier's check or by
wire transfer to an account designated by the Company in an amount equal to the
Exercise Price multiplied by the number of shares being purchased.

     4.   No Fractional Shares or Scrip.  No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of this
Warrant.

     5.   Charges, Taxes and Expenses.  Issuance of certificates for shares of
Common Stock upon the exercise of this Warrant shall be made without charge to
the holder hereof for any issue or transfer tax or other incidental expense in
respect of the issuance of such certificate, all of which taxes and expenses
shall be paid by the Company, and such certificates shall be issued in the name
of the holder of this Warrant or in such name or names as may be directed by the
holder of this Warrant; provided, however, that in the event certificates for
shares of Common Stock are to be issued in a name other than the name of the
holder of this Warrant, this Warrant when surrendered for exercise shall be
accompanied by the Assignment Form attached hereto duly executed by the holder
hereof; and provided further, that upon any transfer involved in the issuance or
delivery of any certificates for shares of Common Stock, the Company may
require, as a condition thereto, the payment of a sum sufficient to reimburse it
for any transfer tax incidental thereto.

     6.   Restrictions on Transfer.

     (a)  This Warrant has been issued subject to investment representations of
the original Holder hereof and may be transferred or exchanged only in
compliance with the Securities Act and applicable state securities laws and in
compliance with the restrictions on transfer provided in the Agreement. The
transferee shall be bound, as the original Holder by the same representations
and terms described herein and under the Agreement. This Warrant and any Warrant
Shares may not be sold, transferred, pledged, hypothecated or otherwise disposed
of except as follows: (i) to a person who, in the opinion of counsel to the
Company, is a person to whom this Warrant or the Warrant Shares may legally be
transferred without registration and without the delivery of a current
prospectus under the Act with respect thereto, and then only against receipt of
an agreement of such person to comply with the provisions of this Section 6(a)
with respect to any resale or other disposition of such securities; or (ii) to
any person upon delivery of a prospectus then meeting the requirements of the
Act relating to such securities and the offering thereof for such sale or
disposition, and thereafter to all successive assignees.

     (b)  Unless the Warrant Shares have been registered under the Act, or
exempt from registration, upon exercise of any of the Warrant and the issuance
of any of the Warrant Shares, all certificates representing Warrant Shares shall
bear on the face thereof substantially the following legend:

          "THESE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"). SUCH
     SECURITIES MAY NOT BE OFFERED OR SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH
     REGISTRATION OR AN 

                                       2
<PAGE>
 
     EXEMPTION THEREFROM UNDER SAID ACT."

     7.   Closing of Books.  The Company will at no time close its shareholder
books or records in any manner which interferes with the timely exercise of this
Warrant.

     8.   No Rights as Shareholder until Exercise.  This Warrant does not
entitle the holder hereof to any voting rights or other rights as a shareholder
of the Company prior to the exercise thereof. If, however, at the time of the
surrender of this Warrant and purchase the holder hereof shall be entitled to
exercise this Warrant, the shares so purchased shall be and be deemed to be
issued to such holder as the record owner of such shares as of the close of
business on the date on which this Warrant shall have been exercised.

     9.   Loss, Theft, Destruction or Mutilation of Warrant.  The Company
represents and warrants that upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of any Warrant
or stock certificate, and in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to it, and upon reimbursement to the Company of
all reasonable expenses incidental thereto, and upon surrender and cancellation
of such Warrant or stock certificate, if mutilated, the Company will make and
deliver a new Warrant or stock certificate of like tenor and dated as of such
cancellation, in lieu of this Warrant or stock certificate.

     10.  Saturdays, Sundays, Holidays, etc.  If the last or appointed day for
the taking of any action or the expiration of any right required or granted
herein shall be a Saturday, Sunday or a legal holiday, then such action may be
taken or such right may be exercised on the next succeeding day not a legal
holiday.

     11.  Effect of Certain Events.  In case the Company shall at any time prior
to the Termination Date effect a Sale or Merger Transaction, and the acquiror
does not assume the obligations hereunder so that the holder of this Warrant has
the right thereafter to purchase, by exercise of this Warrant and payment of the
aggregate Exercise Price in effect immediately prior to such action, the kind
and amount of shares and other securities and property which it would have owned
or have been entitled to receive after the happening of such transaction had
this Warrant been exercised immediately prior thereto. The holder hereof shall
be given at least ten days notice prior to the effective date of such
transaction and shall have the right to exercise this Warrant immediately prior
to the transaction, whether or not this Warrant is then exercisable, and to
participate in such transaction on the same basis as other holders of Common
Stock. In the event this Warrant is being exercised under such circumstances
immediately prior to a Sale or Merger Transaction, then the Warrant may be
exercised on a cashless basis in which, in lieu of paying the Exercise Price in
cash, the holder may surrender the right to receive upon exercise that number of
shares of Common Stock determined by multiplying the number of Warrant Shares to
which the holder would otherwise be entitled by a fraction, the numerator of
which shall be the amount by which the then current market price per share of
Common Stock exceeds the Exercise Price, and the denominator of which will be
the then current market price per share of Common Stock.

                                       3
<PAGE>
 
     12.  Adjustments of Exercise Price and Number of Warrant Shares.  The
number and kind of securities purchasable upon the exercise of this Warrant and
the Exercise Price shall be subject to adjustment from time to time upon the
happening of any of the following.

     In case the Company shall (i) declare or pay a dividend in shares of Common
Stock or make a distribution in shares of Common Stock to holders of its
outstanding Common Stock, (ii) subdivide its outstanding shares of Common Stock,
(iii) combine its outstanding shares of Common Stock into a smaller number of
shares of Common Stock or (iv) issue any shares of its capital stock in a
reclassification of the Common Stock, the number of Warrant Shares purchasable
upon exercise of this Warrant immediately prior thereto shall be adjusted so
that the holder of this Warrant shall be entitled to receive the kind and number
of Warrant Shares or other securities of the Company which he would have owned
or have been entitled to receive had such Warrant been exercised in advance
thereof. An adjustment made pursuant to this paragraph shall become effective
immediately after the effective date of such event retroactive to the record
date, if any, for such event.

     13.  Voluntary Adjustment by the Company.  The Company may at its
discretion, at any time during the term of this Warrant, reduce the then current
Exercise Price to any amount and for any period of time deemed appropriate by
the Board of Directors of the Company.

     14.  Notice of Adjustment.  Whenever the number of Warrant Shares or number
or kind of securities or other property purchasable upon the exercise of this
Warrant or the Exercise Price is adjusted, as herein provided, the Company shall
promptly mail by registered or certified mail, return receipt requested, to the
holder of this Warrant notice of such adjustment or adjustments setting forth
the number of Warrant Shares (and other securities or property) purchasable upon
the exercise of this Warrant and the Exercise Price of such Warrant Shares after
such adjustment, setting forth a brief statement of the facts requiring such
adjustment and setting forth computation by which such adjustment was made. Such
notice, in absence of manifest error, shall be conclusive evidence of the
correctness of such adjustment.

     15.  Purchase Rights.  If at any time after the date hereof, the Company
grants, issues, sells or distributes any options, convertible securities or
rights to purchase stock, warrants, securities or other property pro rate to the
record holders 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 full
exercise of this Warrant (without taking into account any limitations or
restrictions on the timing or amount of exercise) immediately before the date on
which a record is taken for the grant, issuance, sale or distribution 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 or
other distribution of such Purchase Rights.

     16.  Authorized Shares.  The Company covenants that during the period the
Warrant is outstanding, it will reserve from its authorized and unissued Common
Stock a sufficient number of shares to provide for the issuance of Common Stock
upon the exercise of any purchase rights under this Warrant. The Company further
covenants that its issuance of this Warrant shall constitute full authority to
its officers who are charged with the duty of executing stock certificates 

                                       4
<PAGE>
 
to execute and issue the necessary certificates for shares of the Company's
Common Stock upon the exercise of the purchase rights under this Warrant. The
Company will take all such reasonable action as may be necessary to assure that
such shares of Common Stock may be issued as provided herein without violation
of any applicable law or regulation, or of any requirements of the Nasdaq
National Market or any domestic securities exchange upon which the Common Stock
may be listed.

     17.  Limitation on Number of Warrant Shares.  Notwithstanding any other
provision herein, the Company shall not be obligated to issue any Warrant Shares
upon exercise of this Warrant or any other warrants issued pursuant to the
Agreement or conversion of any shares of Preferred Stock issued pursuant to the
Agreement ("Preferred Stock") 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 or any other warrants issued pursuant to the
Agreement or conversion of any shares of Preferred Stock issued pursuant to the
Agreement (the "Exchange Cap") without breaching the Company's obligations under
the rules or regulations of The Nasdaq Stock Market, Inc., except that such
limitation shall not apply in the event that the Company (a) obtains the
approval of its stockholders as required by NASD Rule 4460 (or any successor
rule or regulation) for issuances of Common Stock in excess of such amount, or
(ii) obtains a written opinion from outside counsel to the Company that such
approval is not required, which opinion shall be reasonably satisfactory to the
holders of Warrants representing a majority of the Warrant Shares then issuable
upon exercise of outstanding 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 to the extent the number of shares of Common Stock
issued to such holder upon conversion of Preferred Stock plus the number of
Warrant Shares issued upon exercise of this Warrant would be greater than such
holder's Cap Allocation Amount (as defined in the applicable Statement of
Designations for such Preferred Stock). In the event the Company is prohibited
from issuing Warrant Shares as a result of the operation of this Section, the
Company shall redeem for cash those Warrant Shares which can not be issued at a
price equal to amount by which the then-current market price exceeds the
Exercise Price of such Warrant Shares as of the date of the attempted exercise.

     19.  Miscellaneous.

     (a)  Issue Date; Jurisdiction.  The provisions of this Warrant shall be
construed and shall be given effect in all respects as if it had been issued and
delivered by the Company on the date hereof. This Warrant shall be binding upon
any successors or assigns of the Company. This Warrant shall constitute a
contract under the laws and jurisdictions of New York and for all purposes shall
be construed in accordance with and governed by the laws of said state without
regard to its conflict of law, principles or rules.

     (b)  Restrictions.  The holder hereof acknowledges that the Common Stock
acquired upon the exercise of this Warrant, if not registered, may have
restrictions upon its resale imposed by state and federal securities laws.

     (c)  Modification and Waiver.  This Warrant and any provisions hereof may
be changed, waived, discharged or terminated only by an instrument in writing
signed by the party against which enforcement of the same is sought.

                                       5

     (d)  Notices.  Any notice, request or other document required or permitted
to be given or delivered to the holders hereof of the Company shall be delivered

holder at its address as shown on the books of the Company or to the Company at
the address set forth in the Agreement.

                        Pursuant to Article 2.13 of the

resolutions were adopted by the Board of Directors of the Company on July 20,
1998 pursuant to authority of the Board of Directors as required by Article 2.13
of the Texas Business Corporation Act.

          RESOLVED, that pursuant to the authority granted to and vested in the
     Board of Directors of this Company (the "BOARD OF DIRECTORS" or the
     "BOARD") in accordance with the provisions of its Articles of
     Incorporation, the Board of Directors hereby authorizes a series of the

               ---------------------------------                          
     series, which consists of 750 shares of Preferred Stock, is the Series F
     Convertible Preferred Stock (the "PREFERRED SHARES") and the stated value
     shall be One Thousand Dollars ($1,000.00) per share (the "STATED VALUE").
     The Preferred Shares shall not bear any dividends.

          2.   Holder's Conversion of Preferred Shares.  A holder of Preferred
               ---------------------------------------                        
     Shares shall have the right, at such holder's option, to convert the
     Preferred Shares into shares of the Company's common stock, no par value
     per share (the "COMMON STOCK"), on the following terms and conditions:

               a.   Conversion Right.  Subject to the provisions of Section 11
                    ----------------                                          
     below, at any time or times on or after the earliest of the first
     anniversary of the Issuance Date (as defined below), the Mandatory
     Conversion Date (as defined below) or the occurrence of a Triggering Event
     (as defined below), any holder of Preferred Shares shall be entitled to
     convert any whole number of Preferred Shares into fully paid and
     nonassessable shares (rounded to the nearest whole share in accordance with
     Section 2(i) below) of Common Stock, at the Conversion Rate (as defined
     below); provided, however, that in no event shall any holder be entitled to
     convert Preferred Shares in excess of that number of Preferred Shares
     which, upon giving effect to such conversion, 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 conversion. 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 conversion of the Preferred Shares with respect to which the
     determination of such proviso is being made, but shall exclude the number
     of shares of Common Stock which would be issuable upon (i) conversion of
     the remaining, nonconverted Preferred Shares beneficially owned by the
     holder and its affiliates and (ii) exercise or conversion of the
     unexercised or unconverted portion of any other securities of the Company
     (including, without limitation, any warrants) subject to a limitation on
     conversion or exercise analogous to the limitation contained herein
     beneficially owned by the holder and its affiliates. 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. Each holder may waive the
     foregoing limitation with respect to its conversions by written notice to
     the Company upon not less than 61 days prior notice (with such waiver
     taking effect only upon the expiration of such 61 day notice period), and
     such limitation shall not apply to conversions as of the Mandatory
     Conversion Date.

               b.   Conversion Rate. Subject to the other provisions hereof,
                    ---------------                                         
     each of the Preferred Shares shall be convertible, at the option of the
     holder, into that number of shares of fully paid and nonassessable shares
     of Common Stock which is to be derived from dividing the Stated Value by
     the Conversion Price (the "Conversion Rate).
 
     For purposes of this Statement of Designation, the following terms shall
have the following meanings:

               The "CLOSING BID PRICE" shall mean, for any security as of any
date, the last closing bid price for such security on the Nasdaq National Market
as reported by Bloomberg Financial Markets ("BLOOMBERG"), or, if the Nasdaq
National Market is not the principal trading market for such security, the last
closing bid price of such security on the principal securities exchange or
trading market where such security is listed or traded as reported by Bloomberg,
or if the foregoing do not apply, the last closing bid price of such security in
the over-the-counter market

                                      -2-
<PAGE>
 
on the electronic bulletin board for such security as reported by Bloomberg, or,
if no closing bid price is reported for such security by Bloomberg, the last
closing trade price of such security as reported by Bloomberg, or, if no last
closing trade price is reported for such security by Bloomberg, the average of
the bid prices of any market makers for such security as reported in the "pink
sheets" by the National Quotation Bureau, Inc. If the Closing Bid Price cannot
be calculated for such security on such date on any of the foregoing bases, the
Closing Bid Price of such security on such date shall be the fair market value
as mutually determined by the Company and the holders of a majority of the
outstanding Preferred Shares. If the Company and the holders of Preferred Shares
are unable to agree upon the fair market value of the Common Stock, then such
dispute shall be resolved pursuant to Section 2(g)(iii) below with the term
"Closing Bid Price" being substituted for the term "Market Price". To the extent
required hereunder, all such determinations of the Closing Bid Price shall be
appropriately adjusted for any stock dividend, stock split or other similar
transaction.

               "CONVERSION PRICE" means, as of any Conversion Date (as defined
below) or other date of determination, the Fixed Conversion Price.

               "FIXED CONVERSION PRICE" means ____ ($___), subject to adjustment
as provided herein. [Prior to filing this Statement the Company shall fill in
the blank with the Market Price (as defined below) of the Common Stock on the
date of the Company's Call pursuant to the Purchase Agreement.]

               "ISSUANCE DATE" shall mean, with respect to each Preferred Share,
the date of issuance of the applicable Preferred Share.

               "MARKET PRICE" shall mean, with respect to any security for any
date, the arithmetic average of the Closing Bid Price for such security on each
of the five consecutive trading days immediately preceding such date.

               c.   Premium.  The Preferred Shares shall bear a non-compounding
                    -------                                                    
premium at the rate of eight (8%) percent per annum. Accrual of such premium
shall commence on the Issuance Date. The premium on each Preferred Share shall
be payable by the Company upon conversion of the Preferred Share, at the
Company's option, in cash or, subject to the Exchange Cap as provided in Section
11, in shares of Common Stock (valued at the Market Price on the Conversion
Date) which have been previously registered by the Company for resale by the
holder of the Preferred Shares. The premium on each Preferred Share shall be
payable solely in cash by the Company upon redemption thereof or liquidation.

               d.   Adjustment to Conversion Price -- Dilution and Other Events.
                    -----------------------------------------------------------
In order to prevent dilution of the rights granted under this Statement of
Designation, the Conversion Price will be subject to adjustment from time to
time as provided in this Section 2(d).
                         -------      

                   (i) Adjustment of Fixed Conversion Price upon Issuance of
                       -----------------------------------------------------
Common Stock. If and whenever on or after the date of issuance of the Preferred
- ------------
Shares, the Company issues or sells, or is deemed to have issued or sold, any
shares of Common Stock (other than shares of Common Stock deemed to have been
issued by the Company in connection with 

                                      -3-
<PAGE>
 
Approved Issuances (as defined below)) for a consideration per share less than
the Market Price in effect immediately prior to such time (the "APPLICABLE
PRICE"), then immediately after such issue or sale, the Fixed Conversion Price
shall be reduced to an amount equal to the product of (x) the Fixed Conversion
Price in effect immediately prior to such issue or sale and (y) the quotient
determined by dividing (1) the sum of (I) the product of the Applicable Price
and the number of shares of Common Stock Deemed Outstanding (as defined below)
immediately prior to such issue or sale, and (II) the consideration, if any,
received by the Company upon such issue or sale, by (2) the product of (I) the
Applicable Price and (II) the number of shares of Common Stock Deemed
Outstanding immediately after such issue or sale. For purposes of determining
the adjusted Fixed Conversion Price under this Section 2(d)(i), the following
shall be applicable:

               (A) Issuance of Options.  If the Company in any manner grants any
                   -------------------                                          
     rights or options to subscribe for or to purchase Common Stock (other than
     in connection with an Approved Issuance or upon conversion of the Preferred
     Shares) or any stock or other securities convertible into or exchangeable
     for Common Stock (such rights or options being herein called "OPTIONS" and
     such convertible or exchangeable stock or securities being herein called
     "CONVERTIBLE SECURITIES") and the price per share for which Common Stock is
     issuable upon the exercise of such Options or upon conversion or exchange
     of such Convertible Securities is less than the Applicable Price, then the
     total maximum number of shares of Common Stock issuable upon the exercise
     of such Options or upon conversion or exchange of the total maximum amount
     of such Convertible Securities issuable upon the exercise of such Options
     shall be deemed to be outstanding and to have been issued and sold by the
     Company for such price per share. For purposes of this Section 2(d)(i)(A),
     the "price per share for which Common Stock is issuable upon exercise of
     such Options or upon conversion or exchange of such Convertible Securities"
     is determined by dividing (I) the total amount, if any, received or
     receivable by the Company as consideration for the granting of such
     Options, plus the minimum aggregate amount of additional consideration
     payable to the Company upon the exercise of all such Options, plus in the
     case of such Options which relate to Convertible Securities, the minimum
     aggregate amount of additional consideration, if any, payable to the
     Company upon the issuance or sale of such Convertible Securities and the
     conversion or exchange thereof, by (II) the total maximum number of shares
     of Common Stock issuable upon exercise of such Options or upon the
     conversion or exchange of all such Convertible Securities issuable upon the
     exercise of such Options. No adjustment of the Fixed Conversion 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 or exchange of such
     Convertible Securities.

               (B) Issuance of Convertible Securities. If the Company in any
                   ----------------------------------                
     manner issues or sells any Convertible Securities and the price per share
     for which Common Stock is issuable upon such conversion or exchange is less
     than the Applicable Price, then the maximum number of shares of Common
     Stock issuable upon conversion or exchange of such Convertible Securities
     shall be deemed to be outstanding and to have been issued and sold by the
     Company for such price per share. For the purposes of this Section
     2(d)(i)(B), the "price per share for which Common Stock is issuable upon
     such conversion or exchange" is determined by dividing (I) the total amount
     received or receivable by the 

                                      -4-
<PAGE>
 
     Company as consideration for the issue or sale of such Convertible
     Securities, plus the minimum aggregate amount of additional consideration,
     if any, payable to the Company upon the conversion or exchange thereof, by
     (II) the total maximum number of shares of Common Stock issuable upon the
     conversion or exchange of all such Convertible Securities. No adjustment of
     the Fixed Conversion Price shall be made upon the actual issue of such
     Common Stock upon conversion or exchange 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 Fixed Conversion Price
     had been or are to be made pursuant to other provisions of this Section
     2(d)(i), no further adjustment of the Fixed Conversion Price shall be made
     by reason of such issue or sale.

               (C) Change in Option Price or Rate of Conversion. If the purchase
                   ---------------------------------------------
     price provided for in any Options, the additional consideration, if any,
     payable upon the issue, conversion or exchange of any Convertible
     Securities, or the rate at which any Convertible Securities are convertible
     into or exchangeable for Common Stock change at any time, the Fixed
     Conversion Price in effect at the time of such change shall be readjusted
     to the Fixed Conversion Price which would have been in effect at such time
     had such Options or Convertible Securities still outstanding 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;
     provided that no adjustment shall be made if such adjustment would result
     in an increase of the Fixed Conversion Price then in effect.

               (D) Certain Definitions. For purposes of determining the adjusted
                   -------------------                   
     Fixed Conversion Price under this Section 2(d)(i), the following terms have
     meanings set forth below:

                   (I) "APPROVED ISSUANCES" shall mean (i) a loan from a
     commercial bank, (ii) any transaction involving the Company's issuances of
     securities (A) as consideration in a merger or consolidation or (B) as
     consideration for the acquisition of a business, product or license or
     other assets by the Company, (iii) the issuance of Common Stock in a firm
     commitment, underwritten public offering, (iv) the issuance of securities
     upon exercise or conversion of the Company's options, warrants or other
     convertible securities outstanding as of the date hereof, (v) the grant of
     additional options or warrants, or the issuance of additional securities,
     under any Company stock option plan, restricted stock plan, stock purchase
     plan or other plan or written compensation contract for the benefit of the
     Company's employees, consultants or directors, (vi) the issuance of
     securities pursuant to the Rights Agreement, dated September 15, 1997,
     between the Company and ChaseMellon Shareholder Services, L.L.C., as
     amended from time to time in accordance with its terms (the "Rights
     Agreement"), and (vii) the issuance of securities pursuant to the Purchase
     Agreement, or in connection with any of the transactions related thereto.

                   (II) "COMMON STOCK DEEMED OUTSTANDING" means, at any given
     time, the number of shares of Common Stock actually outstanding at such
     time, plus the number of shares of Common Stock deemed to be outstanding
     pursuant to Sections 2(d)(i)(A) and 2(d)(i)(B) hereof regardless of whether
     the Options or Convertible 

                                      -5-
<PAGE>
 
     Securities are actually exercisable at such time, but excluding any shares
     of Common Stock issuable upon conversion of the Preferred Shares.

               (E) Treatment of Expired Options and Unexercised Convertible
                   --------------------------------------------------------
     Securities.  If, in any case, the total number of shares of Common Stock
     ----------                                                              
     issuable upon the exercise of any Option or upon exercise, conversion or
     exchange of any Convertible Security is not, in fact, issued and the rights
     to exercise such Option or to exercise, convert or exchange such
     Convertible Securities shall have expired or terminated, the Fixed
     Conversion Price then in effect will be readjusted to the Fixed Conversion
     Price which would have been effect at the time of such expiration or
     termination had such Option or Convertible Securities, to the extent
     outstanding immediately prior to such expiration or termination (other than
     in respect of the actual number of shares of Common Stock issued upon
     exercise or conversion thereof), never been issued.

               (F) Effect on Fixed Conversion Price of Certain Events. For
                   --------------------------------------------------
     purposes of determining the adjusted Fixed Conversion Price under this
     Section 2(d)(i), the following shall be applicable:

                   (I)  Calculation of Consideration Received. 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 amount received by the Company therefor, before
     deduction of reasonable commissions, underwriting discounts or allowances
     or other reasonable expenses paid or incurred by the Company in connection
     with such issuance or sale. In case any Common Stock, Options or
     Convertible Securities are issued or sold for a consideration other than
     cash, the amount of the consideration other than cash received by the
     Company will be the fair value of such consideration, except where such
     consideration consists of securities, in which case the amount of
     consideration received by the Company will be the Market Price of such
     security on the date of receipt. In case 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 a
     majority of the Preferred Shares 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 forty-eight (48) hours of the tenth
     (10th) day following the Valuation Event by an independent, reputable
     appraiser selected by the Company. The determination of such appraiser
     shall be deemed binding upon all parties absent manifest error.

                   (II) Integrated Transactions. 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 for
     purposes of Section 2(d)(i)(A).

                                      -6-
<PAGE>
 
               (III) Treasury Shares. The number of shares of Common Stock
                     ---------------                                 
     outstanding at any given time does not include shares owned or held by or
     for the account of the Company, and the disposition of any shares so owned
     or held will be considered an issue or sale of Common Stock.

               (IV)  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 (assuming such issuance
     ultimately occurs).

          (ii) Adjustment of Fixed Conversion Price upon Subdivision or
               --------------------------------------------------------
     Combination of Common Stock.  If the Company at any time subdivides (by any
     ---------------------------                                                
     stock split, stock dividend, recapitalization or otherwise) one or more
     classes of its outstanding shares of Common Stock into a greater number of
     shares, the Fixed Conversion Price in effect immediately prior to such
     subdivision will be proportionately reduced. If the Company at any
     time 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 Fixed Conversion Price in effect immediately
     prior to such combination will be proportionately increased.

          (iii)     Intentionally omitted.
 
          (iv) Reorganization, Reclassification, Consolidation, Merger or Sale.
               ---------------------------------------------------------------  
     Any recapitalization, reorganization, reclassification, consolidation,
     merger, sale of all or substantially all of the Company's assets to another
     Person (as defined below) or other transaction which is effected in such a
     way that holders of Common Stock are entitled to receive (either directly
     or upon subsequent liquidation) stock, securities or assets with respect to
     or in exchange for Common Stock, other than a Major Transaction, is
     referred to herein as "ORGANIC CHANGE." Prior to the consummation of any
     Organic Change, the Company will appropriate provision (in form and
     substance reasonably satisfactory to the holders of a majority of the
     Preferred Shares then outstanding) to insure that each of the holders of
     the Preferred Shares will thereafter have the right to acquire and receive
     in lieu of or addition to (as the case may be) the shares of Common Stock
     otherwise acquirable and receivable upon the conversion of such holder's
     Preferred Shares, 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 conversion of such holder's Preferred
     Shares had such Organic Change not taken place (without taking into account
     any limitations or restrictions on the timing or amount of conversions). In
     any such case, the Company will make appropriate provision (in form and
     substance reasonably satisfactory to the holders of a majority of the
     Preferred Shares then outstanding) with respect to such holders' rights and

                                      -7-
<PAGE>
 
     interests to insure that the provisions of this Section 2(d) and Section
     2(e) below will thereafter be applicable to the Preferred Shares
     (including, in the case of any such consolidation, merger or sale in which
     the successor entity or purchasing entity is other than the Company, an
     immediate adjustment of the Fixed Conversion Price to the value for the
     Common Stock reflected by the terms of such consolidation, merger or sale,
     if the value so reflected is less than the Fixed Conversion Price in effect
     immediately prior to such consolidation, merger or sale). The Company will
     not effect any such consolidation, merger or sale, other than a Major
     Transaction, unless prior to the consummation thereof, the successor entity
     (if other than the Company) resulting from consolidation or merger or the
     entity purchasing such assets assumes, by written instrument, the
     obligation to deliver to each holder of Preferred Shares such shares of
     stock, securities or assets as, in accordance with the foregoing
     provisions, such holder may be entitled to acquire. "PERSON" shall mean an
     individual, a limited liability company, a partnership, a joint venture, a
     corporation, a trust, an unincorporated organization and a government or
     any department or agency thereof.

          (v) Certain Events.  If any event occurs of the type contemplated by
              --------------                                                  
     the provisions of this Section 2(d) 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 Conversion Price so as to protect the rights of the
     holders of the Preferred Shares; provided that no such adjustment will
     increase the Conversion Price as otherwise determined pursuant to this
     Section 2(d).

          (vi) Notices.
               --------

               (A) Immediately upon any adjustment of the Conversion Price, the
     Company will give written notice thereof to each holder of Preferred
     Shares, setting forth in reasonable detail and certifying the calculation
     of such adjustment.

               (B) The Company will give written notice to each holder of
     Preferred Shares at least twenty (20) days prior to the date on which the
     Company closes its books or takes a record (I) with respect to any dividend
     or distribution upon the Common Stock, (II) with respect to any pro rata
     subscription offer to holders of Common Stock or (III) for determining
     rights to vote with respect to any Organic Change, dissolution or
     liquidation and in no event shall such notice be provided to such holder
     prior to such information being made known to the public.

               (C) The Company will also give written notice to each holder of
     Preferred Shares at least twenty (20) days prior to the date on which any
     Organic Change, dissolution or liquidation will take place and in no event
     shall such notice be provided to such holder prior to such information
     being made known to the public.

          e.   Purchase Rights.  In addition to any adjustments of the
               ---------------                                        
Conversion Price pursuant to Section 2(d) above, if at any time after the
Issuance Date the Company grants, issues or sells any Options, Convertible
Securities or rights to purchase stock, warrants, securities or

                                      -8-

other property pro rata to the record holders of any class of Common Stock (the
"PURCHASE RIGHTS"), then the holders of Preferred Shares 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 conversion of the
Preferred Shares (without taking into account any limitations or restrictions on
the timing or amount of conversions) 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.

          g.   Mechanics of Conversion.  Subject to the Company's inability
               -----------------------                                     
to fully satisfy its obligations under a Conversion Notice (as defined below) as
provided for in Section 4 below:

               (i)  Holder's Delivery Requirements. To convert Preferred Shares
                    ------------------------------                             
     into full shares of Common Stock on any date (the "CONVERSION DATE"), the
     holder thereof shall (A) transmit by facsimile (or otherwise deliver), for
     receipt on or prior to 11:59 p.m., Eastern Time on such date, a copy of a
     fully executed notice of conversion in the form attached hereto as Exhibit
     I (the "CONVERSION NOTICE"), to the Company, and (B) surrender to a common
     carrier for delivery to the Company as soon as practicable following such
     date, the original certificates representing the Preferred Shares being
     converted (or an indemnification undertaking with respect to such shares in
     the case of their loss, theft or destruction) (the "PREFERRED STOCK
     CERTIFICATES") and the originally executed Conversion Notice.

               (ii) Company's Response. Upon receipt by the Company of a
                    ------------------                                       
     facsimile copy of a Conversion Notice, the Company shall immediately send,
     via facsimile, a confirmation of receipt of such Conversion Notice to such
     holder. Upon receipt by the Company of the Preferred Stock Certificates to
     be converted pursuant to a Conversion Notice, together with the originally
     executed Conversion Notice, the Company or its designated transfer agent
     (the "TRANSFER AGENT") (as applicable) shall, on the next business day
     following the date of receipt of both (or the second business day following
     the date of receipt of both if received after 11:00 a.m. local time of the
     Company), (I) issue and surrender to a common carrier for overnight
     delivery to the address as specified in the Conversion 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, or
     (II) 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 The Depository Trust Company. If the number of Preferred Shares
     represented by the Preferred Stock Certificate(s) submitted for conversion
     is greater than the number of Preferred Shares being converted, then the
     Company shall, as soon as practicable and in no event later than two
     business days after receipt of the Preferred Stock Certificate(s) and at
     its own expense, issue and deliver to the holder a new Preferred Stock
     Certificate representing the number of Preferred Shares not converted.

               (iii)  Dispute Resolution.  In the case of a dispute as
                      ------------------                              
     to the determination of the Market Price or the arithmetic calculation of
     the Conversion Rate, 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 as soon as possible, but in no event later than two (2) business
     days after receipt of such holder's Conversion Notice. If such holder and
     the Company are unable to agree upon the determination of the Market Price
     or arithmetic calculation of the Conversion Rate within one (1) business
     day of such disputed determination or arithmetic calculation being
     submitted to the holder, then the Company shall within one (1) business day
     submit via facsimile (A) the disputed determination of the Market Price to
     an independent, reputable investment bank or (B) the disputed arithmetic
     calculation of the Conversion Rate to its independent, outside accountant.
     The Company shall cause the investment bank 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 forty-eight (48) hours
     from the time it receives the disputed determinations or calculations. Such
     investment bank's or accountant's determination or calculation, as the case
     may be, shall be binding upon all parties absent manifest error. The period
     of time in which the Company is required to effect conversions or
     redemptions under this Statement of Designations shall be tolled with
     respect to the subject conversion or redemption pending resolution of any
     dispute by the Company made in good faith and in accordance with this
     Section 2(g)(iii).

               (iv)   Record Holder. The person or persons entitled to receive
                      -------------      
     the shares of Common Stock issuable upon a conversion of Preferred Shares
     shall be treated for all purposes as the record holder or holders of such
     shares of Common Stock on the Conversion Date.

               (v)    Company's Failure to Timely Convert. If within three (3)
                      -----------------------------------                     
     business days of the Company's receipt of the Conversion Notice (the "SHARE
     DELIVERY PERIOD") the Company shall fail to issue a certificate to a holder
     for the number of shares of Common Stock to which such holder is entitled
     upon such holder's conversion of Preferred Shares or to issue a new
     Preferred Stock Certificate representing the number of Preferred Shares to
     which such holder is entitled pursuant to Section 2(g)(ii) (a "CONVERSION
     FAILURE"), in addition to all other available remedies which such holder
     may pursue hereunder and under the Purchase Agreement between the Company
     and the initial holders of the Preferred Shares (the " PURCHASE AGREEMENT")
     (including indemnification), the Company shall pay additional damages to
     such holder for each business day after such third (3rd) business day that
     such conversion is not timely effected in an amount equal to two (2%)
     percent per month of the product of (A) the number of shares of Common
     Stock not issued to the holder on a timely basis pursuant to Section
     2(g)(ii) and to which such holder is entitled, and (B) the Closing Bid
     Price of the Common Stock on the last possible date which the Company could
     have issued such Common Stock to such holder without violating Section
     2(g)(ii). If the Company fails to pay the additional damages set forth in
     this Section 2(g)(v) within five business days of the date incurred, then
     the holder entitled to such payments shall have the right at any time, so
     long as the Company continues to fail to make such payments, to require the
     Company, upon written notice, to immediately issue, in lieu of

                                      -10-
<PAGE>
 
     the cash additional damages set forth in this Section 2(g)(v), the number
     of shares of Common Stock equal to the quotient of (X) the aggregate amount
     of the additional damages payments described above divided by (Y) the
     Market Price in effect on such Conversion Date as is specified by the
     holder in writing to the Company. Payment of the additional damages shall
     not relieve the Company of its obligation to send the shares of Common
     Stock to the holder upon conversion.

               h.   Mandatory Conversion. Subject to Section 11, if any
                    --------------------             
     Preferred Shares remain outstanding on the Mandatory Conversion Date (as
     defined below), then all such Preferred Shares shall be converted as of
     such date in accordance with this Section 2 as if the holders of such
     Preferred Shares had given the Conversion Notice on the Mandatory
     Conversion Date; provided, however, that if a Triggering Event has occurred
     and is continuing on the Mandatory Conversion Date, then the Company shall,
     within five business days following the Mandatory Conversion Date (unless
     otherwise notified in writing by the holder of its request to have the
     Preferred Shares converted into Common Stock), pay to each holder of
     Preferred Shares then outstanding, in immediately available funds, an
     amount equal to the Triggering Event Redemption Price as of the Mandatory
     Conversion Date. All holders of Preferred Shares shall thereupon surrender
     all Preferred Stock Certificates, duly endorsed for cancellation, to the
     Company or the Transfer Agent, provided that the Company has complied with
     its obligations under this Section 2(h). Notwithstanding the foregoing,
     except in the case of a Major Transaction, if the Common Stock is not
     designated for quotation on the Nasdaq National Market or listed on The New
     York Stock Exchange, Inc. or The American Stock Exchange, Inc. but such
     events do not constitute a Triggering Event, then the Mandatory Conversion
     Date shall be extended until the Common Stock is so designated or listed.
     "MANDATORY CONVERSION DATE" means the date which is the earlier of five
     years after the applicable Issuance Date, subject to extension as described
     in the immediately preceding sentence, or immediately prior to a Major
     Transaction.

               i.   Fractional Shares.  The Company shall not issue any fraction
                    -----------------                                           
     of a share of Common Stock upon any conversion. All shares of Common Stock
     (including fractions thereof) issuable upon conversion of more than one
     Preferred Share by a holder thereof shall be aggregated for purposes of
     determining whether the conversion would result in the issuance of a
     fraction of a share of Common Stock. If, after the aforementioned
     aggregation, the issuance would result in the issuance of a fraction of a
     share of Common Stock, the Company shall round such fraction of a share of
     Common Stock up or down to the nearest whole share.

               j.   Taxes.  The Company shall pay any and all taxes which may be
                    -----                                                       
     imposed upon it with respect to the issuance and delivery of Common Stock
     upon the conversion of the Preferred Shares.

               ------------------------------- 

               a.   Redemption Option Upon Major Transaction.  In addition to
                    ----------------------------------------

     Preferred Shares at a price per Preferred Share equal to 120% of the
     Liquidation Preference (as defined in Section 8 below) ("MAJOR TRANSACTION
     REDEMPTION PRICE").

               b.   Redemption Option Upon Triggering Event.  In addition to all
                    ---------------------------------------                     
     other rights of the holders of Preferred Shares contained herein, after a
     Triggering Event (as defined below), each holder of Preferred Shares shall
     have the right, at such holder's option, to require the Company to redeem
     all or a portion of such holder's Preferred Shares at a price per Preferred
     Share equal to 120% of the Liquidation Preference ("TRIGGERING EVENT
     REDEMPTION PRICE" and, collectively with "MAJOR TRANSACTION REDEMPTION
     PRICE," the "REDEMPTION PRICE").

               c.   "Major Transaction".  A "MAJOR TRANSACTION" shall be deemed
                    -------------------                                        
     to have occurred at such time as any of the following events:
     
                    (i)   the consolidation, merger or other business
     combination of the Company with or into another Person which requires or
     receives the consent or recommendation of the Company's Board of Directors
     (excluding a consolidation, merger or other business combination in which
     holders of the Company's voting power immediately prior to the transaction
     continue after the transaction to hold, directly or indirectly, the voting
     power of the surviving entity or entities necessary to elect a majority of
     the members of the board of directors (or their equivalent if other than a
     corporation) of such entity or entities and excluding a short-form merger
     effected without the consent or recommendation of the Company's Board of
     Directors) (an "EXEMPT MAJOR TRANSACTION").

                    (ii)  the sale or transfer of all or substantially all of
     the Company's assets or rights to the "Be There!" business or product line
     other than in connection with a disposition to a subsidiary of the Company;
     or

                    (iii) consummation of a purchase, tender or exchange offer
     made to the holders of more than 50% of the outstanding shares of Common
     Stock which requires or receives the consent or recommendation of the
     Company's Board of Directors.

               d.   "Triggering Event".  A "TRIGGERING EVENT" shall be deemed to
                    ------------------                                          
     have occurred at such time as any of the following events (other than in
     connection with a Major Transaction):

                    (i)   the failure of the Registration Statement to be
     declared effective by the SEC on or prior to the date that is 150 days
     after the Demand;

<PAGE>
 
                    (ii)  while the Registration Statement is required to be
     maintained effective pursuant to the terms of the Registration Rights
     Agreement, the effectiveness of the Registration Statement lapses for any
     reason (including, without limitation, the issuance of a stop order) or is
     unavailable to the holder of the Preferred Shares for sale of all of the
     Registrable Securities (as defined in the Registration Rights Agreement) in
     accordance with the terms of the Registration Rights Agreement, and such
     lapse or unavailability continues for a period of thirty (30) consecutive
     trading days, provided that the cause of such lapse or unavailability is
     not due to factors solely within the control of such holder of Preferred
     Shares;

                    (iii) the Company undertakes any voluntary action to
     terminate the quotation or listing of the Common Stock on the Nasdaq
     National Market, The New York Stock Exchange, Inc. or The American Stock
     Exchange, Inc., unless such action is taken in connection with the
     continued quotation or listing of the Common Stock on another of the Nasdaq
     National Market, The New York Stock Exchange, Inc. or The American Stock
     Exchange, Inc.;

                    (iv)  the Company's failure to deliver shares of Common
     Stock within 15 days of its receipt of a Conversion Notice (together with
     the Preferred Stock Certificate) or the Company's notice to any holder of
     Preferred Shares, including by way of public announcement, at any time, of
     its intention not to comply with proper requests for conversion of any
     Preferred Shares into shares of Common Stock, other than due to any of the
     reasons set forth in Section 4(a) below; or

                    (v)   if the Company pursuant to or within the meaning of
     Title 11, U.S. Code, or any similar federal or state law for the relief of
     debtors ("BANKRUPTCY LAW"), (I) commences a voluntary case, (II) consents

               e.   Mechanics of Redemption at Option of Buyer Upon Major

     Transaction.  No sooner than 15 days nor later than 10 days prior to the
     -----------                                                             
     consummation of a Major Transaction, but not prior to the public
     announcement of such Major Transaction, the Company shall deliver written
     notice thereof via facsimile and overnight courier ("NOTICE OF MAJOR
     TRANSACTION") to each holder of Preferred Shares. At any time after receipt
     of a Notice of Major Transaction (or, in the event a Notice of Major
     Transaction is not delivered at least 10 days prior to a Major Transaction,
     at any time within 10 days prior to a Major Transaction), any holder of
     Preferred Shares then outstanding may require the Company to redeem,
     effective immediately prior to the consummation of such Major Transaction,
     all of the holder's Preferred Shares then outstanding by delivering written
     notice thereof via facsimile and overnight courier ("NOTICE OF REDEMPTION
     AT OPTION OF BUYER UPON MAJOR TRANSACTION") to the Company, which Notice of
     Redemption at Option of Buyer Upon Major Transaction shall indicate (i) the
     number of Preferred Shares that such holder is 

                                      -13-
<PAGE>
 
     electing to redeem and (ii) the applicable Major Transaction Redemption
     Price, as calculated pursuant to Section 3(a) above. Preferred Shares which
     are not required to be redeemed pursuant to this paragraph are subject to
     mandatory conversion as provided herein.

               f.   Mechanics of Redemption at Option of Buyer Upon Triggering
                    ----------------------------------------------------------
     Event.  Within one (1) day after the occurrence of a Triggering Event, the
     -----                                                                     
     Company shall deliver written notice thereof via facsimile and overnight
     courier ("NOTICE OF TRIGGERING EVENT") to each holder of Preferred Shares.
     At any time after the earlier of a holder's receipt of a Notice of
     Triggering Event and such holder becoming aware of a Triggering Event, any
     holder of Preferred Shares then outstanding may require the Company to
     redeem all of the Preferred Shares by delivering written notice thereof via
     facsimile and overnight courier ("NOTICE OF REDEMPTION AT OPTION OF BUYER
     UPON TRIGGERING EVENT") to the Company, which Notice of Redemption at
     Option of Buyer Upon Triggering Event shall indicate (i) the number of
     Preferred Shares that such holder is electing to redeem and (ii) the
     applicable Triggering Event Redemption Price, as calculated pursuant to
     Section 3(b) above.

               g.   Payment of Redemption Price.  Upon the Company's receipt of
                    ---------------------------                                
     a Notice(s) of Redemption at Option of Buyer Upon Triggering Event or a
     Notice(s) of Redemption at Option of Buyer Upon Major Transaction from any
     holder of Preferred Shares or Pari Passu Shares (as defined in Section 8),
     the Company shall immediately notify each holder of Preferred Shares and
     Pari Passu Shares by facsimile of the Company's receipt of such Notice(s)
     of Redemption at Option of Buyer Upon Triggering Event or Notice(s) of
     Redemption at Option of Buyer Upon Major Transaction and each holder which
     has sent such a notice shall promptly submit to the Company or its Transfer
     Agent such holder's Preferred Stock Certificates which such holder has
     elected to have redeemed. The Company shall deliver the applicable
     Triggering Event Redemption Price, in the case of a redemption pursuant to
     Section 3(f), to such holder within five business days after the Company's
     receipt of a Notice of Redemption at Option of Buyer Upon Triggering Event
     and, in the case of a redemption pursuant to Section 3(e), the Company
     shall deliver the applicable Major Transaction Redemption Price immediately
     prior to the consummation of the Major Transaction; provided that a
     holder's Preferred Stock Certificates shall have been so delivered to the
     Company; provided further that if the Company is unable to redeem all of
     the Preferred Shares and Pari Passu Shares to be redeemed (because of
     insufficient funds to lawfully effect such redemption), the Company shall
     redeem an amount from each holder of Preferred Shares and Pari Passu Shares
     being redeemed equal to such holder's pro-rata amount (based on the
     relative redemption amounts of all holders of Preferred Shares and Pari
     Passu Shares) of all Preferred Shares and Pari Passu Shares being redeemed.
     If the Company shall fail to redeem all of the Preferred Shares submitted
     for redemption (other than pursuant to a dispute as to the arithmetic
     calculation of the Redemption Price), in addition to any remedy such holder
     of Preferred Shares may have under this Statement of Designations and the
     Purchase Agreement, the applicable Redemption Price payable in respect of
     such unredeemed Preferred Shares shall bear interest at the rate of 2.0%
     per month (prorated for partial months) until paid in full. Until the
     Company pays such unpaid applicable Redemption Price in full to a holder of
     Preferred Shares submitted for redemption, such holder shall have the
     option (the "VOID OPTIONAL REDEMPTION OPTION") to, in lieu of redemption,
     require the Company to promptly return to such holder(s) all of the

                                      -14-
<PAGE>
 
     Preferred Shares that were submitted for redemption by such holder(s) under
     this Section 3 and for which the applicable Redemption Price has not been
     paid, by sending written notice thereof to the Company via facsimile (the
     "VOID OPTIONAL REDEMPTION NOTICE"). Upon the Company's receipt of such Void
     Optional Redemption Notice(s) and prior to payment of the full applicable
     Redemption Price to such holder, (i) the Notice(s) of Redemption at Option
     of Buyer Upon Triggering Event or the Notice(s) of Redemption at Option of
     Buyer Upon Major Transaction, as the case may be, shall be null and void
     with respect to those Preferred Shares submitted for redemption and for
     which the applicable Redemption Price has not been paid, and (ii) the
     Company shall immediately return any Preferred Shares submitted to the
     Company by each holder for redemption under this Section 3(g) and for which
     the applicable Redemption Price has not been paid. Notwithstanding the
     foregoing, in the event of a dispute as to the determination of the Closing
     Bid Price or the arithmetic calculation of the Redemption Price, such
     dispute shall be resolved pursuant to Section 2(g)(iii) above with the term
     "Closing Bid Price" being substituted for the term "Average Market Price"
     and the term "Redemption Price" being substituted for the term "Conversion
     Rate". A holder's delivery of a Void Optional Redemption Notice and
     exercise of its rights follo wing such notice shall not affect the
     Company's obligations to make any payments which have accrued prior to the
     date of such notice. Payments provided for in this Section 3 shall have
     priority to payments to other stockholders, other than any required
     payments with respect to shares of the Company's Series A Convertible
     Preferred Stock which were outstanding on the Issuance Date, in connection
     with a Major Transaction.

          4.   Inability to Fully Convert.

               a.   Holder's Option if Company Cannot Fully Convert.  If, upon
                    -----------------------------------------------           
     the Company's receipt of a Conversion Notice or on the Mandatory Conversion
     Date, the Company can not issue shares of Common Stock registered for
     resale under the Registration Statement for any reason, including, without
     limitation, because the Company (x) does not have a sufficient number of
     shares of Common Stock authorized and available, (y) is otherwise
     prohibited by applicable law or by the rules or regulations of any stock
     exchange, interdealer quotation system or other self-regulatory
     organization with jurisdiction over the Company or its Securities,
     including without limitation the Exchange Cap, from issuing all of the
     Common Stock which is to be issued to a holder of Preferred Shares pursuant
     to a Conversion Notice or (z) fails to have a sufficient number of shares
     of Common Stock registered for resale under the Registration Statement,
     then the Company shall issue as many shares of Common Stock as it is able
     to issue in accordance with such holder's Conversion Notice and pursuant to
     Section 2(g) above and, with respect to the unconverted Preferred Shares,
     the holder, solely at such holder's option, can elect to:

                    (i) require the Company to redeem from such holder those
     Preferred Shares for which the Company is unable to issue Common Stock in
     accordance with such holder's Conversion Notice ("MANDATORY REDEMPTION") at
     a price per Preferred Share (the "MANDATORY REDEMPTION PRICE") equal to the
     Triggering Event Redemption Price as of such Conversion Date;

                                      -15-
<PAGE>
 
                    (ii)  if the Company's inability to fully convert Preferred
     Shares is pursuant to Section 4(a)(z) above, require the Company to issue
     restricted shares of Common Stock in accordance with such holder's
     Conversion Notice and pursuant to Section 2(g) above;

                    (iii) void its Conversion Notice and retain or have
     returned, as the case may be, the nonconverted Preferred Shares that were
     to be converted pursuant to such holder's Conversion Notice (provided that
     a holder's voiding its Conversion Notice shall not effect the Company's
     obligations to make any payments which have accrued prior to the date of
     such notice); or

                    (iv)  if the Company's inability to fully convert Preferred
     Shares is pursuant to the Exchange Cap described in Section 4(a)(y) above,
     and the issuance of additional Conversion Shares at a Conversion Price
     equal to the Market Price would not violate the rules or regulations of The
     Nasdaq Stock Market, Inc., then, subject to Section 11, require the Company
     to issue shares of Common Stock in accordance with such holder's Conversion
     Notice and pursuant to Section 2(g) above at a Conversion Price equal to
     the Market Price of the Common Stock on the date of such holder's Notice in
     Response to Inability to Convert (as defined below).

               b.   Mechanics of Fulfilling Holder's Election.  The Company
                    -----------------------------------------              
     shall immediately send via facsimile to a holder of Preferred Shares, upon
     receipt of a facsimile copy of a Conversion Notice from such holder which
     cannot be fully satisfied as described in Section 4(a) above, a notice of
     the Company's inability to fully satisfy such holder's Conversion Notice
     (the "INABILITY TO FULLY CONVERT NOTICE"). Such Inability to Fully Convert
     Notice shall indicate (i) the reason why the Company is unable to fully
     satisfy such holder's Conversion Notice, (ii) the number of Preferred
     Shares which cannot be converted and (iii) the applicable Mandatory
     Redemption Price. Such holder shall notify the Company of its election
     pursuant to Section 4(a) above by delivering written notice via facsimile
     to the Company ("NOTICE IN RESPONSE TO INABILITY TO CONVERT").

               c.   Payment of Redemption Price.  If such holder shall elect to
                    ---------------------------                                
     have its shares redeemed pursuant to Section 4(a)(i) above, the Company
     shall pay the Mandatory Redemption Price in cash to such holder within
     thirty (30) days of the Company's receipt of the holder's Notice in
     Response to Inability to Convert, provided that prior to the Company's
     receipt of the holder's Notice in Response to Inability to Convert the
     Company has not delivered a notice to such holder stating, to the
     satisfaction of the holder, that the event or condition resulting in the
     Mandatory Redemption has been cured and all Conversion Shares issuable to
     such holder can and will be delivered to the holder in accordance with the
     terms of Section 2(g). If the Company shall fail to pay the applicable
     Mandatory Redemption Price to such holder on a timely basis as described in
     this Section 4(c) (other than pursuant to a dispute as to the determination
     of the arithmetic calculation of the Redemption Price), in addition to any
     remedy such holder of Preferred Shares may have under this Statement of
     Designations and the Securities Purchase Agreement, such unpaid amount
     shall bear interest at the rate of 2.0% per month (prorated for partial
     months) until paid in full. Until the full Mandatory Redemption Price is
     paid in full to such holder, such holder may void the

                                      -16-
<PAGE>
 
     Mandatory Redemption with respect to those Preferred Shares for which the
     full Mandatory Redemption Price has not been paid and receive back such
     Preferred Shares. Notwithstanding the foregoing, if the Company fails to
     pay the applicable Mandatory Redemption Price within such thirty (30) days
     time period due to a dispute as to the determination of the arithmetic
     calculation of the Redemption Rate, such dispute shall be resolved pursuant
     to Section 2(g)(iii) above with the term "Redemption Price" being
     substituted for the term "Conversion Rate".

               d.   Pro-rata Conversion and Redemption.  In the event the
                    ----------------------------------                   
     Company receives a Conversion Notice from more than one holder of Preferred
     Shares or Pari Passu Shares on the same day and the Company can convert and
     redeem some, but not all, of the Preferred Shares or Pari Passu Shares
     pursuant to this Section 4, the Company shall convert and redeem from each
     holder of Preferred Shares or Pari Passu Shares electing to have Preferred
     Shares or Pari Passu Shares converted and redeemed at such time an amount
     equal to such holder's pro-rata amount (based on the relative redemption
     amounts of all holders of Preferred Shares and Pari Passu shares) of all
     Preferred Shares and Pari Passu Shares being converted and redeemed at such
     time.

               e.   Involuntary Delisting. In the event the Common Stock at any
                    ---------------------   
     time is not designated for quotation on the Nasdaq National Market or
     listed on The New York Stock Exchange, Inc. or The American Stock Exchange,
     Inc. but such events do not constitute a Triggering Event and are not in
     connection with a Major Transaction, then in addition to any other remedies
     the holders of Preferred Shares may have at law or in equity, the Company
     shall pay to each holder of Preferred Shares an amount in cash per
     Preferred Share on each day that the Common Stock is not so designated or
     listed equal to the product of the Liquidation Preference multiplied by
     1.0%, provided that the Company shall not be required to make such payments
     for more than 24 consecutive days. The Company's failure to pay such
     amounts on each day they are due shall constitute a Triggering Event for
     purposes of Section 3.

          5.   Reissuance of Certificates.  In the event of a conversion or
               --------------------------                                  
     redemption pursuant to this Statement of Designations of less than all of
     the Preferred Shares represented by a particular Preferred Stock
     Certificate, the Company shall promptly cause to be issued and delivered to
     the holder of such Preferred Shares a preferred stock certificate
     representing the remaining Preferred Shares which have not been so
     converted or redeemed.

          6.   Reservation of Shares.  Subject to the Exchange Cap in Section
               ---------------------                                         
     11, the Company shall, so long as any of the Preferred Shares are
     outstanding, reserve and keep available out of its authorized and unissued
     Common Stock, solely for the purpose of effecting the conversion of the
     Preferred Shares, such number of shares of Common Stock as shall from time
     to time be sufficient to effect the conversion of all of the Preferred
     Shares then outstanding; provided that the number of shares of Common Stock
     so reserved shall at no time be less than 200% of the number of shares of
     Common Stock for which the Preferred Shares are at any time convertible
     (subject to the Exchange Cap if lower). The initial number of shares of
     Common Stock reserved for conversions of the Preferred Shares and each
     increase in the number of shares so reserved shall be allocated pro rata
     among the 

                                      -17-
<PAGE>
 
     holders of the Preferred Shares based on the number of Preferred Shares
     held by each holder at the time of issuance of the Preferred Shares or
     increase in the number of reserved shares, as the case may be. In the event
     a holder shall sell or otherwise transfer any of such holder's Preferred
     Shares, each transferee shall be allocated a pro rata portion of the number
     of reserved shares of Common Stock reserved for such transferor. Any shares
     of Common Stock reserved and which remain allocated to any person or entity
     which does not hold any Preferred Shares shall be allocated to the
     remaining holders of Preferred Shares, pro rata based on the number of
     Preferred Shares then held by such holder.

          7.   Voting Rights.  Holders of Preferred Shares shall have no voting
               -------------                                                   
     rights (including with respect to a Major Transaction), except as expressly
     required by law, including but not limited to the Texas Business
     Corporation Act, and as expressly provided in this Statement of
     Designations.

          8.   Liquidation, Dissolution, Winding-Up.  In the event of any
               ------------------------------------                      
     voluntary or involuntary liquidation, dissolution or winding up of the
     Company, the holders of the Preferred Shares shall be entitled to receive
     in cash out of the assets of the Company, whether from capital or from
     earnings available for distribution to its stockholders (the "PREFERRED
     FUNDS"), after all required payments with respect to shares of the
     Company's Series A Convertible Preferred Stock which were outstanding on
     the Issuance Date, but before any amount shall be paid to the holders of
     any of the capital stock of the Company of any class junior in rank to the
     Preferred Shares in respect of the preferences as to the distributions and
     payments on the liquidation, dissolution and winding up of the Company, an
     amount per Preferred Share equal to the Stated Value plus all accrued and
     unpaid premium thereon (such sum being referred to as the "LIQUIDATION
     PREFERENCE"); provided that, if the Preferred Funds are insufficient to pay
     the full amount due to the holders of Preferred Shares and holders of the
     Company's Series D Convertible Preferred Stock and Series E Convertible
     Preferred Stock (the "Pari Passu Shares"), which are of equal rank with the
     Preferred Shares as to payments of Preferred Funds (and redemption
     amounts), then each holder of Preferred Shares and Pari Passu Shares shall
     receive a percentage of the Preferred Funds equal to the full amount of
     Preferred Funds payable to such holder as a liquidation preference, in
     accordance with their respective Statement of Designations, Preferences and
     Rights, as a percentage of the full amount of Preferred Funds payable to
     all holders of Preferred Shares and Pari Passu Shares. The purchase or
     redemption by the Company of stock of any class, in any manner permitted by
     law, shall not, for the purposes hereof, be regarded as a liquidation,
     dissolution or winding up of the Company. Neither the consolidation or
     merger of the Company with or into any other Person, nor the sale or
     transfer by the Company of less than substantially all of its assets,
     shall, for the purposes hereof, be deemed to be a liquidation, dissolution
     or winding up of the Company. No holder of Preferred Shares shall be
     entitled to receive any amounts with respect thereto upon any liquidation,
     dissolution or winding up of the Company other than the amounts provided
     for herein; provided that a holder of Preferred Shares shall be entitled to
     all amounts previously accrued with respect to amounts owed hereunder.

          9.   Preferred Rank; Participation.  (i)  All shares of Common Stock
               -----------------------------                                  
     shall be of junior rank to all Preferred Shares and Pari Passu Shares in
     respect to the preferences as to

                                      -18-
<PAGE>
 
     distributions and payments upon the liquidation, dissolution and winding up
     of the Company. The rights of the shares of Common Stock shall be subject
     to the preferences and relative rights of the Preferred Shares and Pari
     Passu Shares. Without the prior express written consent of the holders of
     not less than three-fourths (3/4) of the then outstanding Preferred Shares
     and Pari Passu Shares, the Company shall not hereafter authorize or issue
     additional or other capital stock that is of senior or equal rank to the
     Preferred Shares and Pari Passu Shares in respect of the preferences as to
     distributions and payments upon the liquidation, dissolution and winding up
     of the Company. Without the prior express written consent of the holders of
     not less than three-fourths (3/4) of the then outstanding Preferred Shares
     and Pari Passu Shares, the Company shall not hereafter authorize or make
     any amendment to the Company's Articles of Incorporation or bylaws, or file
     any resolution of the board of directors of the Company with the Texas
     Secretary of State containing any provisions, which would adversely affect
     or otherwise impair the rights or relative priority of the holders of the
     Preferred Shares and Pari Passu Shares relative to the holders of the
     Common Stock or the holders of any other class of capital stock; provided
     that the foregoing shall not affect the Company's ability to effect a Major
     Transaction. In the event of the merger or consolidation of the Company
     with or into another corporation (other than a Major Transaction), the
     Preferred Shares and Pari Passu Shares shall maintain their relative
     powers, designations and preferences provided for herein and no merger
     shall result inconsistent therewith.


          (ii) Subject to the rights of the holders, if any, of the Parri Passu
     Shares, the holders of the Preferred Shares shall, as holders of Preferred
     Stock, be entitled to such dividends paid and distributions made to the
     holders of Common Stock to the same extent as if such holders of Preferred
     Shares had converted the Preferred Shares into Common Stock (without regard
     to any limitations on conversion herein or elsewhere) and had held such
     shares of Common Stock on the record date for such dividends and
     distributions. Payments under the preceding sentence shall be made
     concurrently with the dividend or distribution to the holders of Common
     Stock; provided that the holders of the Preferred Shares shall be entitled
     to such dividends and distributions only to the extent that they exceed an
     amount per Preferred Share equal to $1,000, plus the accrued premium
     thereon.

          10.  Restriction on Redemption and Cash Dividends with respect to
               ------------------------------------------------------------
     Other Capital Stock. Until all of the Preferred Shares have been converted
     -------------------     
     or redeemed as provided herein, except as permitted in the Rights
     Agreement, the Company shall not, directly or indirectly, redeem, or
     declare or pay any cash dividend or cash distribution on, its Common Stock
     without the prior express written consent of the holders of not less than
     two-thirds (2/3) of the then outstanding Preferred Shares.

          11.  Limitation on Number of Conversion Shares.  Notwithstanding any
               -----------------------------------------                      
     other provision herein, the Company shall not be obligated to issue any
     shares of Common Stock upon conversion of the Preferred Shares and Pari
     Passu Shares if the issuance of such shares of Common Stock would exceed
     that number of shares of Common Stock which the Company may issue upon
     Conversion of the Preferred Shares and Pari Passu Shares (the "EXCHANGE
     CAP") without breaching the Company's obligations under the rules or
     regulations of The Nasdaq Stock Market, Inc., except that such limitation
     shall not apply in 
     

                                      -19-
<PAGE>
 
     the event that the Company (a) obtains the approval of its stockholders as
     required by NASD Rule 4460 (or any successor rule or regulation) for
     issuances of Common Stock in excess of such amount or (ii) obtains a
     written opinion from outside counsel to the Company that such approval is
     not required, which opinion shall be reasonably satisfactory to the holders
     of a majority of the Preferred Shares then outstanding. Until such approval
     or written opinion is obtained, no purchaser of Preferred Shares and Pari
     Passu Shares pursuant to the Purchase Agreement (the "PURCHASERS") shall be
     issued, upon conversion of Preferred Shares and Pari Passu Shares, shares
     of Common Stock in an amount greater than the product of (i) the Exchange
     Cap amount multiplied by (ii) a fraction, the numerator of which is the
     number of Preferred Shares and Pari Passu Shares issued to such Purchaser
     pursuant to the Purchase Agreement and the denominator of which is the
     aggregate amount of all the Preferred Shares and Pari Passu Shares issued
     to the Purchasers pursuant to the Purchase Agreement (the "CAP ALLOCATION
     AMOUNT"). In the event that any Purchaser shall sell or otherwise transfer
     any of such Purchaser's Preferred Shares and Pari Passu Shares, the
     transferee shall be allocated a pro rata portion of such Purchaser's Cap
     Allocation Amount. In the event that any holder of Preferred Shares and
     Pari Passu Shares shall convert all of such holder's Preferred Shares and
     Pari Passu Shares into a number of shares of Common Stock which, in the
     aggregate, is less than such holder's Cap Allocation Amount, then the
     difference between such holder's Cap Allocation Amount and the number of
     shares of Common Stock actually issued to such holder shall be allocated to
     the respective Cap Allocation Amounts of the remaining holders of Preferred
     Shares and Pari Passu Shares on a pro rata basis in proportion to the
     number of Preferred Shares then held by each such holder.

          12.  Vote to Change the Terms of Preferred Shares.  The affirmative
               --------------------------------------------                  
     vote at a meeting duly called for such purpose or the written consent
     without a meeting, of the holders of not less than two-thirds (2/3) of the
     then outstanding Preferred Shares and Pari Passu Shares, shall be required
     for any change to this Statement of Designations or the Company's
     Certificate of Incorporation which would amend, alter, change or repeal any
     of the powers, designations, preferences and rights of the Preferred
     Shares.

          13.  Lost or Stolen Certificates.  Upon receipt by the Company of
               ---------------------------                                 
     evidence satisfactory to the Company of the loss, theft, destruction or
     mutilation of any Preferred Stock Certificates representing the Preferred
     Shares, and, in the case of loss, theft or destruction, of any
     indemnification undertaking by the holder to the Company and, in the case
     of mutilation, upon surrender and cancellation of the Preferred Stock
     Certificate(s), the Company shall execute and deliver new preferred stock
     certificate(s) of like tenor and date; provided, however, the Company shall
     not be obligated to re-issue preferred stock certificates if the holder
     contemporaneously requests the Company to convert such Preferred Shares
     into Common Stock.

          14.  Remedies, Characterizations, Other Obligations, Breaches and
               ------------------------------------------------------------
     Injunctive Relief.  The remedies provided in this Statement of Designations
     -----------------                                                          
     shall be cumulative and in addition to all other remedies available under
     this Statement of Designations, at law or in equity (including a decree of
     specific performance and/or other injunctive relief), no remedy contained
     herein shall be deemed a waiver of compliance with the provisions giving
     rise to such remedy and nothing herein shall limit a holder's right to
     pursue actual damages for any 

                                      -20-
<PAGE>
 
     failure by the Company to comply with the terms of this Statement of
     Designations. The Company covenants to each holder of Preferred Shares that
     there shall be no characterization concerning this instrument other than as
     expressly provided herein. Amounts set forth or provided for herein with
     respect to payments, conversion and the like (and the computation thereof)
     shall be the amounts to be received by the holder thereof and shall not,
     except as expressly provided herein, be subject to any other obligation of
     the Company (or the performance thereof). The Company acknowledges that a
     breach by it of its obligations hereunder will cause irreparable harm to
     the holders of the Preferred Shares and that the remedy at law for any such
     breach may be inadequate. The Company therefore agrees that, in the event
     of any such breach or threatened breach, the holders of the Preferred
     Shares shall be entitled, in addition to all other available remedies, to
     an injunction restraining any breach, without the necessity of showing
     economic loss and without any bond or other security being required.

          15.  Specific Shall Not Limit General; Construction.  No specific
               ----------------------------------------------              
     provision contained in this Statement of Designations shall limit or modify
     any more general provision contained herein. This Statement of Designations
     shall be deemed to be jointly drafted by the Company and all holders of
     Preferred Shares and shall not be construed against any person as the
     drafter hereof.

          16.  Failure or Indulgence Not Waiver.  No failure or delay on the
               --------------------------------                             
     part of a holder of Preferred Shares in the exercise of any power, right or
     privilege hereunder shall operate as a waiver thereof, nor shall any single
     or partial exercise of any such power, right or privilege preclude other or
     further exercise thereof or of any other right, power or privilege.

                                DATA RACE, INC.
                               CONVERSION NOTICE

Reference is made to the Statement of Designations, Preferences and Rights of
Series F Convertible Preferred Stock (the "STATEMENT OF DESIGNATIONS").  In
accordance with and pursuant to the Statement of Designations, the undersigned
hereby elects to convert the number of shares of Series F Convertible Preferred
Stock, no par value per share (the "PREFERRED SHARES"), of Data Race, Inc., a
Texas corporation (the "COMPANY"), indicated below into shares of Common Stock,
no par value per share (the "COMMON STOCK"), of the Company, by tendering the
stock certificate(s) representing the share(s) of Preferred Shares specified
below as of the date specified below.

     Date of Conversion:
