          Upon the filing of this Amended and Restated Certificate of

Stock shall be automatically split into three (3) shares of this corporation's
Common Stock, without any action by the holder

                                   ARTICLE V

          A.   Classes of Stock.  This corporation is authorized to issue two
               ----------------
classes of stock to be designated, respectively, "Common Stock" and "Preferred
Stock." The total number of shares that this corporation is authorized to issue
is two hundred million (200,000,000) shares. One hundred thirty-two million
(132,000,000) shares shall be Common Stock and sixty-eight million (68,000,000)
shares shall be Preferred Stock, each with a par value of $0.001 per share.

          B.   Rights, Preferences and Restrictions of Preferred Stock.  The
               -------------------------------------------------------
Preferred Stock authorized by this Restated Certificate of Incorporation may be
issued from time to time in one or more series. The rights, preferences,
privileges, and restrictions granted to and imposed on the Series A Preferred
Stock, which series shall consist of thirty-two million (32,000,000) shares (the
"Series A Preferred Stock") and the Series B Preferred Stock, which series shall
consist of thirty-six million (36,000,000) shares (the "Series B Preferred
Stock") are as set forth below in this Article V(B).

          1.   Dividend Provisions.
               -------------------
          (a)  The holders of the Series A Preferred Stock and Series B
Preferred Stock shall be entitled to receive dividends at the rate of $0.05 per
share and $0.43 per share (as adjusted for any stock dividends, combinations or
splits with respect to such shares) per annum, respectively, payable out of
funds legally available therefor. Such dividends shall be payable only when, as,
and if declared by the Board of Directors and shall be noncumulative.

          (b)  No dividends (other than those payable solely in the Common Stock
of the corporation) shall be paid on any Common Stock of the corporation during
any fiscal year of the corporation until dividends in the total amount of $0.05
per share and $0.43 per share (as adjusted for any stock dividends, combinations
or splits with respect to such shares) on the Series A Preferred Stock and
Series B Preferred Stock, respectively, shall have been paid or declared and set
apart during that fiscal year and no dividends shall be paid on any share of
Common Stock unless a dividend (including the amount of any dividends paid
pursuant to the provisions of subsection (a) above) is paid with respect to all
outstanding shares of Series A Preferred Stock and Series B Preferred Stock in
an amount for each such share of Series A Preferred Stock and Series B Preferred
Stock equal to or greater than the aggregate amount of such dividends for all
shares of Common Stock into which each such share of Series A Preferred Stock or
Series B Preferred Stock could then be converted.

          (c)  In the event of a conversion of the Series A Preferred Stock or
Series B Preferred Stock pursuant to Section 4 hereof, any accrued and unpaid
dividends shall be paid at the election of the holder in cash or Common Stock at
its then fair market value, as determined by the Board of Directors.

                                       2


          2.   Liquidation Preference.
               ----------------------

          (a)  In the event of any liquidation, dissolution or winding up of
this corporation, either voluntary or involuntary, the holders of Preferred
Stock shall be entitled to receive, prior and in preference to any distribution
of any of the assets of this corporation to the holders of Common Stock by
reason of their ownership thereof, (A) in the case of the Series A Preferred
Stock an amount per share equal to the sum of (i) $0.67 for each outstanding
share of Series A Preferred Stock (the "Original Series A Issue Price"), and
(ii) an amount equal to declared but unpaid dividends on such share (subject to
adjustment of such fixed dollar amounts for any stock splits, stock dividends,
combinations, recapitalizations or the like), and (B) in the case of the Series
B Preferred Stock, an amount per share equal to the sum of (i) $5.33 for each
outstanding share of Series B Preferred Stock (the "Original Series B Issue
Price"), and (ii) an amount equal to declared but unpaid dividends on such share
(subject to adjustments of such fixed dollar amounts for any stock splits, stock
dividends, combinations, recapitalizations or the like). If upon the occurrence
of such event, the assets and funds thus distributed among the holders of the
Series A Preferred Stock and Series B Preferred Stock shall be insufficient to
permit the payment to such holders of the full aforesaid preferential amounts,
then, the entire assets and funds of this corporation legally available for
distribution shall be distributed ratably among the holders of the Series A
Preferred Stock and Series B Preferred Stock in proportion to the full
preferential amount each such holder is otherwise entitled to receive under this
subsection (a).

          (b)  Upon the completion of the distribution required by subsection
(a) of this Section 2 all of the remaining assets of this corporation available
for distribution to stockholders shall be distributed among the holders of
Common Stock pro rata based on the number of shares of Common Stock held by
each.

          (c)

               (i)  For purposes of this Section 2, a liquidation, dissolution
or winding up of this corporation shall be deemed to be occasioned by, or to
include (unless the holders of at least a majority of the Preferred Stock then
outstanding shall determine otherwise), (A) the acquisition of this corporation
by another entity by means of any transaction or series of related transactions
(including, without limitation, any reorganization, merger or consolidation)
that results in the transfer of fifty percent (50%) or more of the outstanding
voting power of this corporation; or (B) a sale of all or substantially all of
the assets of this corporation.

               (ii) In any of such foregoing events, if the consideration
received by this corporation is other than cash, its value will be deemed its
fair market value. Any securities shall be valued as follows:

                      (A)  Securities not subject to investment letter or other
similar restrictions on free marketability covered by (B) below:

                           (1)   If traded on a securities exchange or through
the Nasdaq National Market, the value shall be deemed to be the average of the
closing prices of the

                                       3


securities on such exchange or system over the thirty (30) day period
ending three (3) days prior to the closing;

                           (2)   If actively traded over-the-counter, the value
shall be deemed to be the average of the closing bid or sale prices (whichever
is applicable) over the thirty (30) day period ending three (3) days prior to
the closing; and

                           (3)   If there is no active public market, the value
shall be the fair market value thereof, as mutually determined by this
corporation and the holders of at least a majority of the voting power of all
then outstanding shares of Preferred Stock.

                       (B) The method of valuation of securities subject to
investment letter or other restrictions on free marketability (other than
restrictions arising solely by virtue of a stockholder's status as an affiliate
or former affiliate) shall be to make an appropriate discount from the market
value determined as above in (A) (1), (2) or (3) to reflect the approximate fair
market value thereof, as mutually determined by this corporation and the holders
of at least a majority of the voting power of all then outstanding shares of
such Preferred Stock.

               (iii) In the event the requirements of this subsection 2(c) are
not complied with, this corporation shall forthwith either:

                       (A)  cause such closing to be postponed until such time
as the requirements of this Section 2 have been complied with; or

                       (B)  cancel such transaction, in which event the rights,
preferences and privileges of the holders of the Preferred Stock shall revert to
and be the same as such rights, preferences and privileges existing immediately
prior to the date of the first notice referred to in subsection 2(c)(iv) hereof.

               (iv)  This corporation shall give each holder of record of
Preferred Stock written notice of such impending transaction not later than
twenty (20) days prior to the stockholders' meeting called to approve such
transaction, or twenty (20) days prior to the closing of such transaction,
whichever is earlier, and shall also notify such holders in writing of the final
approval of such transaction. The first of such notices shall describe the
material terms and conditions of the impending transaction and the provisions of
this Section 2, and this corporation shall thereafter give such holders prompt
notice of any material changes. The transaction shall in no event take place
sooner than twenty (20) days after this corporation has given the first notice
provided for herein or sooner than ten (10) days after this corporation has
given notice of any material changes provided for herein; provided, however,
that such periods may be shortened upon the written consent of the holders of
Preferred Stock that are entitled to such notice rights or similar notice rights
and that represent at least a majority of the voting power of all then
outstanding shares of such Preferred Stock.

          3.   Redemption.  The Preferred Stock is not redeemable.
               ----------

          4.   Conversion.  The holders of the Preferred Stock shall have
               ----------
conversion rights as follows (the "Conversion Rights"):

                                       4


          (a)  Right to Convert.  Each share of Series A Preferred Stock and
               ----------------
Series B Preferred Stock shall be convertible, at the option of the holder
thereof, at any time after the date of issuance of such share, at the office of
this corporation or any transfer agent for such stock, into such number of fully
paid and nonassessable shares of Common Stock as is determined by dividing the
Original Issue Price for such series by the Conversion Price applicable to such
share, determined as hereafter provided, in effect on the date the certificate
is surrendered for conversion. The initial Conversion Price for shares of Series
A Preferred Stock shall be the Original Series A Issue Price and the initial
Conversion Price for shares of Series B Preferred Stock shall be the Original
Series B Issue Price, subject to adjustment as set forth in Section 4(d) hereof.

          (b)  Automatic Conversion.  Each share of Series A Preferred Stock and
               --------------------
Series B Preferred Stock shall automatically be converted into shares of Common
Stock at the Conversion Price at the time in effect for such Series A Preferred
Stock immediately upon the earlier of (i) this corporation's sale of its Common
Stock in a firm commitment underwritten public offering pursuant to a
registration statement on Form S-1 or Form SB-2 under the Securities Act of
1933, as amended, provided that the aggregate gross offering price is at least
$25,000,000 or (ii) upon vote of the holders of a majority of the then
outstanding shares of Preferred Stock (which provision may be amended only by a
majority vote of the holders of the Preferred Stock).

          (c)  Mechanics of Conversion.  Before any holder of Preferred Stock
               -----------------------
shall be entitled to convert the same into shares of Common Stock, he or she
shall surrender the certificate or certificates therefor, duly endorsed, at the
office of this corporation or of any transfer agent for the Preferred Stock, and
shall give written notice to this corporation at its principal corporate office,
of the election to convert the same and shall state therein the name or names in
which the certificate or certificates for shares of Common Stock are to be
issued. This corporation shall, as soon as practicable thereafter, issue and
deliver at such office to such holder of Preferred Stock, or to the nominee or
nominees of such holder, a certificate or certificates for the number of shares
of Common Stock to which such holder shall be entitled as aforesaid. Such
conversion shall be deemed to have been made immediately prior to the close of
business on the date of such surrender of the shares of Preferred Stock to be
converted, and the person or persons entitled to receive the shares of Common
Stock issuable upon such conversion shall be treated for all purposes as the
record holder or holders of such shares of Common Stock as of such date. If the
conversion is in connection with an underwritten offering of securities
registered pursuant to the Securities Act of 1933, the conversion may, at the
option of any holder tendering Preferred Stock for conversion, be conditioned
upon the closing with the underwriters of the sale of securities pursuant to
such offering, in which event the persons entitled to receive the Common Stock
upon conversion of the Preferred Stock shall not be deemed to have converted
such Preferred Stock until immediately prior to the closing of such sale of
securities.

          (d)  Conversion Price Adjustments of Preferred Stock for Certain
               -----------------------------------------------------------
Splits and Combinations.  The Conversion Price of the Series A Preferred Stock
- -----------------------
and Series B Preferred Stock shall be subject to adjustment from time to time as
follows:

               (i)  (A)  If this corporation shall issue, after the date upon
which any shares of Series A Preferred Stock or Series B Preferred Stock were
first issued (the "Purchase

                                       5


Date" with respect to such series, any Additional Stock (as defined below)
without consideration or for a consideration per share less than the Conversion
Price for such series in effect immediately prior to the issuance of such
Additional Stock, the Conversion Price for such series in effect immediately
prior to each such issuance shall forthwith (except as otherwise provided in
this clause (i)) be adjusted to a price determined by multiplying such
Conversion Price by a fraction, the numerator of which shall be the number of
shares of Common Stock outstanding immediately prior to such issuance (including
shares of Common Stock deemed to be issued pursuant to subsection 4(d)(i)(E)(1)
or (2)) plus the number of shares of Common Stock that the aggregate
consideration received by this corporation for such issuance would purchase at
such Conversion Price; and the denominator of which shall be the number of
shares of Common Stock outstanding immediately prior to such issuance (including
shares of Common Stock deemed to be issued pursuant to subsection 4(d)(i)(E)(1)
or (2)) plus the number of shares of Additional Stock.

          (B)  No adjustment of the Conversion Price for the Series A Preferred
Stock or Series B Preferred Stock shall be made in an amount less than one cent
per share, provided that any adjustments that are not required to be made by
reason of this sentence shall be carried forward and shall be either taken into
account in any subsequent adjustment made prior to three (3) years from the date
of the event giving rise to the adjustment being carried forward, or shall be
made at the end of three (3) years from the date of the event giving rise to the
adjustment being carried forward.  Except to the limited extent provided for in
subsections (E)(3) and (E)(4), no adjustment of such Conversion Price pursuant
to this subsection 4(d)(i) shall have the effect of increasing the Conversion
Price above the Conversion Price in effect immediately prior to such adjustment.

          (C)  In the case of the issuance of Common Stock for cash, the
consideration shall be deemed to be the amount of cash paid therefor before
deducting any reasonable discounts, commissions or other expenses allowed, paid
or incurred by this corporation for any underwriting or otherwise in connection
with the issuance and sale thereof.

          (D)  In the case of the issuance of the Common Stock for a
consideration in whole or in part other than cash, the consideration other than
cash shall be deemed to be the fair value thereof as determined by the Board of
Directors as determined in good faith irrespective of any accounting treatment.

          (E)  In the case of the issuance (whether before, on or after the
applicable Purchase Date) of options to purchase or rights to subscribe for
Common Stock, securities by their terms convertible into or exchangeable for
Common Stock or options to purchase or rights to subscribe for such convertible
or exchangeable securities, the following provisions shall apply for all
purposes of this subsection 4(d)(i) and subsection 4(d)(ii):

               (1)  The aggregate maximum number of shares of Common Stock
deliverable upon exercise (assuming the satisfaction of any conditions to
exercisability, including without limitation, the passage of time, but without
taking into account potential antidilution adjustments) of such options to
purchase or rights to subscribe for Common Stock shall be deemed to have been
issued at the time such options or rights were issued and for a consideration
equal to the consideration (determined in the manner provided in subsections

                                       6


4(d)(i)(C) and (d)(i)(D)), if any, received by this corporation upon the
issuance of such options or rights plus the minimum exercise price provided in
such options or rights (without taking into account potential antidilution
adjustments) for the Common Stock covered thereby.

               (2)  The aggregate maximum number of shares of Common Stock
deliverable upon conversion of, or in exchange (assuming the satisfaction of any
conditions to convertibility or exchangeability, including, without limitation,
the passage of time, but without taking into account potential antidilution
adjustments) for, any such convertible or exchangeable securities or upon the
exercise of options to purchase or rights to subscribe for such convertible or
exchangeable securities and subsequent conversion or exchange thereof shall be
deemed to have been issued at the time such securities were issued or such
options or rights were issued and for a consideration equal to the
consideration, if any, received by this corporation for any such securities and
related options or rights (excluding any cash received on account of accrued
interest or accrued dividends), plus the minimum additional consideration, if
any, to be received by this corporation (without taking into account potential
antidilution adjustments) upon the conversion or exchange of such securities or
the exercise of any related options or rights (the consideration in each case to
be determined in the manner provided in subsections 4(d)(i)(C) and (d)(i)(D)).

               (3)  In the event of any change in the number of shares of Common
Stock deliverable or in the consideration payable to this corporation upon
exercise of such options or rights or upon conversion of or in exchange for such
convertible or exchangeable securities, including, but not limited to, a change
resulting from the antidilution provisions thereof (unless such options or
rights or convertible or exchangeable securities were merely deemed to be
included in the numerator and denominator for purposes of determining the number
of shares of Common Stock outstanding for purposes of subsection 4(d)(i)(A)),
the Conversion Price of the Series A Preferred Stock, to the extent in any way
affected by or computed using such options, rights or securities, shall be
recomputed to reflect such change, but no further adjustment shall be made for
the actual issuance of Common Stock or any payment of such consideration upon
the exercise of any such options or rights or the conversion or exchange of such
securities.

               (4)  Upon the expiration of any such options or rights, the
termination of any such rights to convert or exchange or the expiration of any
options or rights related to such convertible or exchangeable securities, the
Conversion Price of the Series A Preferred Stock, to the extent in any way
affected by or computed using such options, rights or securities or options or
rights related to such securities (unless such options or rights were merely
deemed to be included in the numerator and denominator for purposes of
determining the number of shares of Common Stock outstanding for purposes of
subsection 4(d)(i)(A)), shall be recomputed to reflect the issuance of only the
number of shares of Common Stock (and convertible or exchangeable securities
that remain in effect) actually issued upon the exercise of such options or
rights, upon the conversion or exchange of such securities or upon the exercise
of the options or rights related to such securities.

               (5)  The number of shares of Common Stock deemed issued and the
consideration deemed paid therefor pursuant to subsections 4(d)(i)(E)(1) and (2)
shall be

                                       7


appropriately adjusted to reflect any change, termination or expiration of the
type described in either subsection 4(d)(i)(E)(3) or (4).

          (ii)  "Additional Stock" shall mean any shares of Common Stock issued
(or deemed to have been issued pursuant to subsection 4(d)(i)(E)) by this
corporation after the Purchase Date other than:

                    (A)  Common Stock issued pursuant to a the three-for-two
forward stock split described in Article IV hereof;

                    (B)  Shares of Common Stock issuable or issued to employees,
consultants, directors or vendors (if in transactions with primarily non-
financing purposes) of this corporation directly or pursuant to a stock option
plan or restricted stock plan approved by the Board of Directors of this
corporation;

                    (C)  The issuance of stock, warrants or other securities or
rights upon approval by the Company's Board of Directors (including the Series B
Director) to persons or entities with which the Company has business
relationships provided such issuances are for other than primarily equity
financing purposes;

                    (D)  The issuance of securities pursuant to a bona fide,
firmly underwritten public offering of shares of Common Stock, registered under
the Act resulting in proceeds to the Company of at least $25,000,000 in the
aggregate;

                    (E)  The issuance of securities pursuant to the conversion
or exercise of convertible or exercisable securities; or

                    (F)  The issuance of securities in connection with a bona
fide business acquisition of or by the Company, whether by merger,
consolidation, sale of assets, sale or exchange of stock or otherwise.

          (iii) In the event this corporation should at any time or from time to
time after the Purchase Date fix a record date for the effectuation of a split
or subdivision of the outstanding shares of Common Stock without a corresponding
adjustment to the Conversion Price of the Preferred Stock (specifically
excluding the three-for-two split of the outstanding shares of Common Stock,
Series A Preferred Stock and Series B Preferred Stock effected upon the filing
of this Amended and Restated Certificate of Incorporation) the determination of
holders of Common Stock entitled to receive a dividend or other distribution
payable in additional shares of Common Stock or other securities or rights
convertible into, or entitling the holder thereof to receive directly or
indirectly, additional shares of Common Stock (hereinafter referred to as
"Common Stock Equivalents") without payment of any consideration by such holder
for the additional shares of Common Stock or the Common Stock Equivalents
(including the additional shares of Common Stock issuable upon conversion or
exercise thereof), then, as of such record date (or the date of such dividend
distribution, split or subdivision if no record date is fixed), the Conversion
Price of the Series A Preferred Stock and Series B Preferred Stock shall be
appropriately decreased so that the number of shares of Common Stock issuable on
conversion of each share of such series shall be increased in proportion to such
increase of the

                                       8


aggregate of shares of Common Stock outstanding and those issuable with respect
to such Common Stock Equivalents.

               (iv) If the number of shares of Common Stock outstanding at any
time after the Purchase Date is decreased by a combination of the outstanding
shares of Common Stock, then, following the record date of such combination, the
Conversion Price for the Series A Preferred Stock and Series B Preferred Stock
shall be appropriately increased so that the number of shares of Common Stock
issuable on conversion of each share of such series shall be decreased in
proportion to such decrease in outstanding shares.

          (e)  Other Distributions.  In the event this corporation shall declare
               -------------------
a distribution payable in securities of other persons, evidences of indebtedness
issued by this corporation or other persons, assets (excluding cash dividends)
or options or rights not referred to in subsection 4(d)(i), then, in each such
case for the purpose of this subsection 4(e), the holders of the Series A
Preferred Stock and Series B Preferred Stock shall be entitled to a
proportionate share of any such distribution as though they were the holders of
the number of shares of Common Stock of this corporation into which their shares
of Series A Preferred Stock and/or Series B Preferred Stock are convertible as
of the record date fixed for the determination of the holders of Common Stock of
this corporation entitled to receive such distribution.

          (f)  Recapitalizations.  If at any time or from time to time there
               -----------------
shall be a recapitalization of the Common Stock (other than a subdivision,
combination or merger or sale of assets transaction provided for elsewhere in
this Section 4 or Section 2 or the three-for-two forward stock split provided
for in Article IV of this Amended and Restated Certificate of Incorporation)
provision shall be made so that the holders of the Series A Preferred Stock and
Series B Preferred Stock shall thereafter be entitled to receive upon conversion
of the Series A Preferred Stock and/or Series B Preferred Stock the number of
shares of stock or other securities or property of the Corporation or otherwise,
to which a holder of Common Stock deliverable upon conversion would have been
entitled on such recapitalization. In any such case, appropriate adjustment
shall be made in the application of the provisions of this Section 4 with
respect to the rights of the holders of the Series A Preferred Stock and Series
B Preferred Stock after the recapitalization to the end that the provisions of
this Section 4 (including adjustment of the Conversion Price then in effect and
the number of shares purchasable upon conversion of the Series A Preferred Stock
and Series B Preferred Stock) shall be applicable after that event as nearly
equivalent as may be practicable.

          (g)  No Impairment.  This corporation will not, by amendment of its
               -------------
Certificate of Incorporation or through any reorganization, recapitalization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms to be observed or performed hereunder by this
corporation, but will at all times in good faith assist in the carrying out of
all the provisions of this Section 4 and in the taking of all such action as may
be necessary or appropriate in order to protect the Conversion Rights of the
holders of the Series A Preferred Stock and Series B Preferred Stock against

          (h)  No Fractional Shares and Certificate as to Adjustments.
               ------------------------------------------------------

               (i)  No fractional shares shall be issued upon the conversion of
any share or shares of the Series A Preferred Stock or Series B Preferred Stock,
and the number of shares of Common Stock to be issued shall be rounded to the
nearest whole share. Whether or not fractional shares are issuable upon such
conversion shall be determined on the basis of the total number of shares of
Series A Preferred Stock and/or Series B Preferred Stock the holder is at the
time converting into Common Stock and the number of shares of Common Stock
issuable upon such aggregate conversion.


               (ii) Upon the occurrence of each adjustment or readjustment of
the Conversion Price of Series A Preferred Stock or Series B Preferred Stock
pursuant to this Section 4, this corporation, at its expense, shall promptly
compute such adjustment or readjustment in accordance with the terms hereof and
prepare and furnish to each holder of Series A Preferred Stock and Series B
Preferred Stock a certificate executed by the Corporation's President or Chief
Financial Officer setting forth such adjustment or readjustment and showing in
detail the facts upon which such adjustment or readjustment is based. This
corporation shall, upon the written request at any time of any holder of Series
A Preferred Stock or Series B Preferred Stock, furnish or cause to be furnished
to such holder a like certificate setting forth (A) such adjustment and
readjustment, (B) the Conversion Price for such series of Preferred Stock at the
time in effect, and (C) the number of shares of Common Stock and the amount, if
any, of other property that at the time would be received upon the conversion of
a share of Series A Preferred Stock or Series B Preferred Stock.

          (i)  Notices of Record Date.  In the event of any taking by this
               ----------------------
corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, this
corporation shall mail to each holder of Series A Preferred Stock and Series B
Preferred Stock, at least twenty (20) days prior to the date specified therein,
a notice specifying the date on which any such record is to be taken for the
purpose of such dividend, distribution or right, and the amount and character of
such dividend, distribution or right.

          (j)  Reservation of Stock Issuable Upon Conversion.  This corporation
               ---------------------------------------------
shall at all times reserve and keep available out of its authorized but unissued
shares of Common Stock, solely for the purpose of effecting the conversion of
the shares of the Series A Preferred Stock and Series B Preferred Stock, such
number of its shares of Common Stock as shall from time to time be sufficient to
effect the conversion of all outstanding shares of the Series A Preferred Stock
and Series B Preferred Stock; and if at any time the number of authorized but
unissued shares of Common Stock shall not be sufficient to effect the conversion
of all then outstanding shares of the Series A Preferred Stock and Series B
Preferred Stock, in addition to such other remedies as shall be available to the
holder of such Preferred Stock, this corporation will take such corporate action
as may, in the opinion of its counsel, be necessary to increase its authorized
but unissued shares of Common Stock to such number of shares as shall be
sufficient for such purposes, including, without limitation, engaging in best
efforts to obtain the requisite shareholder approval of any necessary amendment
to this Restated Certificate of Incorporation.

                                       10


          (k)  Notices.  Any notice required by the provisions of this Section 4
               -------
to be given to the holders of shares of Series A Preferred Stock and Series B
Preferred Stock shall be deemed given if deposited in the United States mail,
postage prepaid, and addressed to each holder of record at his address appearing
on the books of this corporation.

          5.   Voting Rights.
               -------------

          (a)  General Voting Rights.  Subject to the provisions of Section 5(b)
               ---------------------
hereof, the holder of each share of Preferred Stock shall have the right to one
vote for each share of Common Stock into which such Preferred Stock could then
be converted, and with respect to such vote, such holder shall have full voting
rights and powers equal to the voting rights and powers of the holders of Common
Stock, and shall be entitled, notwithstanding any provision hereof, to notice of
any stockholders' meeting in accordance with the bylaws of this corporation, and
shall be entitled to vote, together with holders of Common Stock, with respect
to any question upon which holders of Common Stock have the right to vote.
Fractional votes shall not, however, be permitted and any fractional voting
rights available on an as-converted basis (after aggregating all shares into
which shares of Preferred Stock held by each holder could be converted) shall be
rounded to the nearest whole number (with one-half being rounded upward).

          (b)  Voting for the Election of Directors.  As long as at least
               ------------------------------------
twenty-five percent (25%) of the shares of Series A Preferred Stock originally
issued remain outstanding, the holders of such shares of Series A Preferred
Stock shall be entitled to elect two (2) directors of this corporation at each
annual election of directors. The holders of outstanding Common Stock shall be
entitled to elect two (2) directors of this corporation at each annual election
of directors. As long as at least twenty-five percent (25%) of the shares of
Series B Preferred Stock originally issued remain outstanding, the holders of
such shares of Series B Preferred Stock shall be entitled to elect one (1)
director of this corporation at each annual election of directors acceptable to
the other directors. The holders of Series A Preferred Stock and Common Stock
(voting together as a single class and not as separate series, and on an as-
converted basis) shall be entitled to elect any remaining directors of this
corporation, provided such directors are approved by the directors elected by
the holders of Common Stock and the directors elected by the holders of
Preferred Stock.

          In the case of any vacancy (other than a vacancy caused by removal) in
the office of a director occurring among the directors elected by the holders of
a class or series of stock pursuant to this Section 5(b), the remaining
directors so elected by that class or series may by affirmative vote of a
majority thereof (or the remaining director so elected if there be but one, or
if there are no such directors remaining, by the affirmative vote of the holders
of a majority of the shares of that class or series), elect a successor or
successors to hold office for the unexpired term of the director or directors
whose place or places shall be vacant.  Any director who shall have been elected
by the holders of a class or series of stock or by any directors so elected as
provided in the immediately preceding sentence hereof may be removed during the
aforesaid term of office, either with or without cause, by, and only by, the
affirmative vote of the holders of the shares of the class or series of stock
entitled to elect such director or directors, given either at a special meeting
of such stockholders duly called for that purpose or pursuant to a written
consent of stockholders, and any vacancy thereby created may be filled by the
holders of that class or series of stock represented at the meeting or pursuant
to unanimous written consent.

          6.   Protective Provisions.  So long as 4,500,000 shares of Preferred
               ---------------------
Stock are outstanding (after taking into account the three-for-two forward stock
split effected upon the filing of this Amended and Restated Certificate), this
corporation shall not without first obtaining the approval (by vote or written
consent, as provided by law) of the holders of at least a majority of the then
outstanding shares of Series A Preferred Stock and Series B Preferred Stock
(voting together as a single class and not as a separate series, and on an as-
converted basis; provided, however that such majority vote shall include the
vote of at least 1,875,000 shares of the holders of Series B Preferred Stock,
after taking into account the three-for-two forward stock split effected upon
the filing of this Amended and Restated Certificate):

          (a)  sell, convey, or otherwise dispose of all or substantially all of
its property or business or merge into or consolidate with any other corporation
(other than a wholly-owned subsidiary corporation) or effect any transaction or
series of related transactions in which more than fifty percent (50%) of the
voting power of this corporation is disposed of;

          (b)  increase the total number of authorized shares of Series A
Preferred Stock or Series B Preferred Stock;

or greater rights than the Series A Preferred Stock or Series B Preferred Stock
with respect to dividends, liquidation, redemption, conversion or voting;

          (d)  redeem, purchase or otherwise acquire (or pay into or set aside
for a sinking fund for such purpose) any share or shares of Preferred Stock or
Common Stock; provided, however, that this restriction shall not apply to the
repurchase of shares of Common Stock from employees, officers, directors,
consultants or other persons performing services for this corporation or any
subsidiary pursuant to agreements under which this corporation has the option to
repurchase such shares at cost upon the occurrence of certain events, such as
the termination of employment;

          (e)  alter or change the rights, preferences or privileges of the
shares of Series A Preferred Stock or Series B Preferred Stock so as to affect
adversely the shares;

          (f)  pay any dividends on this corporation's Common Stock; or

          (g)  increase the authorized number of directors of this corporation.

          7.   Status of Converted Stock. In the event any shares of Series A
               -------------------------
Preferred Stock or Series B Preferred Stock shall be converted pursuant to
Section 4 hereof, the shares so converted shall be cancelled and shall not be
issuable by this corporation. The Restated Certificate of Incorporation of this
corporation shall be appropriately amended to effect the corresponding reduction
in this corporation's authorized capital stock.

          C.   Common Stock.  The rights, preferences, privileges and
               ------------
restrictions granted to and imposed on the Common Stock are as set forth below

               ---------------
classes of stock at the time outstanding having prior rights as to dividends,
the holders of the Common Stock shall be entitled to receive, when and as
declared by the Board of Directors, out of any assets of this corporation
legally available therefor, such dividends as may be declared from time to time
by the Board of Directors.

          2.   Liquidation Rights.  Upon the liquidation, dissolution or winding
               ------------------
up of this corporation, the assets of this corporation shall be distributed as
