                     RESTATED CERTIFICATE OF INCORPORATION
                                       OF
                                JT STORAGE, INC.

                 (Originally incorporated on February 3, 1994)


         JT Storage, Inc., a corporation organized and existing under the laws
of the State of Delaware, hereby certifies as follows:

         1.      The name of the corporation is JT Storage, Inc.  JT Storage,
Inc. was originally incorporated under the same name, and the original
Certificate of Incorporation of the corporation was filed with the Secretary of
State of the State of Delaware on February 3, 1994.

         2.      Pursuant to Section 241 and 245 of the General Corporation Law
of the State of Delaware, this Restated Certificate of Incorporation restates
and integrates and further amends the provisions of the Certificate of
Incorporation of this corporation.

         3.      The text of the Restated Certificate of Incorporation as
heretofore amended or supplemented is hereby restated and further amended to
read in its entirety as follows:

                                   ARTICLE I

         The name of the corporation (which is hereinafter referred to as the
"CORPORATION") is:

                                JT Storage, Inc.

                                   ARTICLE II

         The address of the Corporation's registered office in the State of
Delaware is 1209 Orange Street in the City of Wilmington, County of New Castle,
Delaware 19801.  The name of the Corporation's registered agent at such address
is The Corporation Trust Company.

                                  ARTICLE III

         The purpose of the Corporation is to engage in any lawful act or
activity for which corporations may be organized under the General Corporation
Law of the State of Delaware.
   2
                                   ARTICLE IV

         (A)     Classes of Stock.  The total number of shares of stock which
the Corporation shall have authority to issue is 40,000,000 shares, consisting
of 24,000,000 shares of Common Stock having a par value of $0.000001 per share
("COMMON STOCK") and 16,000,000 shares of Preferred Stock, all of which shall
be designated Series A Preferred Stock, par value $0.000001 per share ("SERIES
A PREFERRED").

         Upon the filing of this Restated Certificate of Incorporation, each
one (1) outstanding share of Common stock shall be split into four thousand
five hundred (4,500) shares of Common Stock.

         (B)     Rights, Preferences, Privileges and Restrictions of Preferred
Stock.  The rights, preferences, privileges, restrictions and other matters
relating to the Series A Preferred are as follows:

                 1.       Dividends.

                          (a)     Dividends on Series A Preferred.  The holders
of Series A Preferred shall be entitled to receive, when and as declared by the
Board of Directors (the "BOARD") out of funds legally available therefor,
dividends at the rate of $0.09 per share, per annum, payable in preference and
priority to any payment of any distribution on Common Stock of the Corporation,
appropriately adjusted for any stock split, stock dividend, stock combination
or other recapitalization (a "RECAPITALIZATION") of the Series A Preferred (as
so adjusted, the "DIVIDEND RATE").  Such dividends shall accrue on each share
of Series A Preferred from day to day, whether or not declared, and shall be
cumulative. Such cumulative dividends on the Series A Preferred may be paid, at
the option of the Corporation, in cash or shares of capital stock of the
Corporation, with any shares of capital stock to be valued at the per share
fair market of such capital stock, as determined in good faith by the
Corporation's Board of Directors at the time such dividends are declared.

                          (b)     Dividends on Common Stock.  No dividends or
other distributions shall be made with respect to the Common Stock until all
accrued and unpaid dividends on the Series A Preferred shall have been declared
and paid in full.  In the event the Corporation shall at any time declare or
pay a dividend on the Common Stock, it shall, simultaneously therewith and as
part of such declaration or payment, declare and pay to each holder of Series A
Preferred a dividend equal to the dividend which would be payable to such
holder if the shares of Series A Preferred held by such holder had been
converted into Common Stock on the date of determination of holders of Common
Stock entitled to receive such dividend.

                          (c)     Definition of Distribution.  For purposes of
this Restated Certificate of Incorporation, unless the context otherwise
requires, a "DISTRIBUTION" shall mean the transfer of cash or other property
without consideration, whether by way of dividend or otherwise, payable





                                      -2-
   3
other than in Common Stock, or the purchase or redemption of shares of
Corporation (other than repurchases of Common Stock issued to or held by
employees, directors or consultants of the Corporation or its subsidiaries upon
termination of their employment or services pursuant to agreements providing
for the right of said repurchase) for cash or property.

                 2.       Liquidation Preference.

                          (a)     Series A Preferred.  In the event of any
liquidation, dissolution or winding up of the Corporation, whether voluntary or
involuntary (or the deemed occurrence of such event pursuant to subsection
(c)(i) of this Section 2) (collectively, a "LIQUIDATION"), the holders of
shares of the Series A Preferred shall be entitled to receive, prior and in
preference to any distribution of any assets or surplus funds of the
Corporation to the holders of the Common Stock by reason of their ownership
thereof, an amount equal to $1.00 per share of Series A Preferred then held by
them (as adjusted for any Recapitalization), plus the greater of (i) $0.09 per
share of Series A  Preferred then held by them (as adjusted for any
Recapitalization with respect to such shares and for partial years) per annum
calculated from the original issue date of the shares of Series A Preferred
through the date of distribution, minus all dividends and other distributions
previously made in respect of any shares of Series A Preferred held by them or
(ii) any declared but unpaid dividends for Series A Preferred then held by
them.

         All of the preferential amount to be paid to the holders of the Series
A Preferred under this Section 2(a) shall be paid or set apart for payment
before the payment or setting apart for payment of any amount for, or the
distribution of any assets of the Corporation to, the holders of Common Stock
in connection with any actual or deemed Liquidation.  After the payment or the
setting apart for payment to the holders of the Series A Preferred of the
preferential amounts so payable to them, the remaining assets of the
Corporation available for distribution shall be distributed in accordance with
the provisions of Section 2(b), as applicable.

         If the assets or surplus funds to be distributed are insufficient to
permit the payment to holders of the Series A Preferred of their full
preferential amount, then the entire assets of the Corporation legally
available for distribution shall be distributed ratably among the holders of
Series A Preferred in such a manner that the preferential amount to be
distributed to each such holder shall equal the amount obtained by multiplying
the entire assets and funds of the Corporation legally available for
distribution hereunder by a fraction, the numerator of which shall be the
number of shares of Series A Preferred then held by such holder, and the
denominator of which shall be the total number of shares of Series A Preferred
then outstanding.

                          (b)     Series A Preferred and Common Stock.  After
payment has been made to the holders of the Series A Preferred of the full
amounts to which they shall be entitled as set forth in Section 2(a) above, the
entire remaining assets and funds of the Corporation legally available for
distribution, if any, shall be distributed ratably among the holders of Series
A Preferred and the holders of Common Stock in a manner such that the amount so
distributed to each holder of Common Stock and/or Series A Preferred shall
equal the amount obtained by multiplying the





                                      -3-
   4
entire assets and funds of the Corporation legally available for distribution
pursuant to this Section 2(b) by a fraction, the numerator of which shall be
the sum of the number of shares of Common Stock then held by the holder and the
number of shares of Common Stock issuable upon conversion of the shares of
Series A Preferred then held by the holder, and the denominator of which shall
be the sum of the total number of shares of Common Stock then outstanding and
the total number of shares of Common Stock issuable upon conversion of the
total number of shares of Series A Preferred then outstanding; provided,
however, that if each holder of Series A Preferred would receive a distribution
of at least an aggregate of $5.00 per share of Series A Preferred solely
pursuant to this Section 2(a) and without any distribution pursuant to Section
2(a), then Section 2(a) shall be of no force and effect and the Corporation's
assets available for distribution to its stockholders shall be distributed
among all holders of Series A Preferred and all holders of Common Stock solely
pursuant to this Section 2(b) in proportion to the number of shares of Common
Stock which would be held by each such holder if all shares of Series A
Preferred were converted into Common Stock at the then effective Conversion
Price (as defined in Section 4(a) below).

                          (c)     Special Provisions.

                                  (i)  For purposes of this Section 2, upon the
election of the holders of at least a majority of the then outstanding shares
of Series A Preferred, a Liquidation shall be deemed to occur upon the sale or
transfer of all or substantially all of the Corporation's assets or the
acquisition of the Corporation by another entity, including any merger
consolidation with or into any other corporation and any other transaction or
series of related transactions resulting in the exchange of the outstanding
shares of the Corporation for securities or consideration issued or caused to
be issued by the acquiring entity as a result of which stockholders of the
Corporation immediately prior to the transaction or series of transactions own
less than fifty percent (50%) of the equity securities of the surviving
corporation immediately following the merger, consolidation, sale or transfer
of assets or other transaction or series of transactions.

                                  (ii)  If any assets distributed pursuant to
this Section 2 are other than cash, then the value of such noncash assets shall
be determined by the Board of Directors of the Corporation, acting in good
faith.

                                  (iii)      Each holder of an outstanding
share of Series A Preferred shall be deemed to have consented, for purposes of
Sections 502, 503 and 506 of the General Corporation Law of California, to
distributions made by the Corporation in connection with the repurchase of
shares of Common Stock issued to or held by employees or consultants upon
termination of their employment or services pursuant to agreements between the
Corporation and such persons providing for the corporation's right of said
repurchase.

                 3.       Redemptions.

                                  Redemption of Series A Preferred.  The Series
A Preferred shall not be redeemable by the Corporation prior to January 10,
2000.  On January 10, 2000, January 10,





                                      -4-
   5
2001 and January 10, 2002, (each a "REDEMPTION DATE" and, collectively the
"REDEMPTION DATES"), the Corporation shall redeem, upon the election of a
majority of the holders of Series A Preferred, in cash out of any funds legally
available therefor, one-third (on a pro rata basis as to each stockholder),
one-half (on a pro rata basis as to each stockholder) and all of the
outstanding shares of Series A Preferred, respectively.  Redemptions pursuant
to this Section 3 for the Series A Preferred shall be made at a price of $1.00
per share (appropriately adjusted for any Recapitalization) plus all accrued
but unpaid dividends on such shares as of each such Redemption Date (in each
case, the "REDEMPTION PRICE").  The Corporation need not establish any sinking
fund for the redemption of the Series A Preferred.

                                  At least thirty days prior to each Redemption
Date, written notice shall be mailed, first class postage prepaid, to each
holder of record (at the close of business on the business day next preceding
the day on which notice is given) of the Series A Preferred at the address last
known on the records of the Corporation for such holder, notifying such holder
of the redemption to be effected, specifying the number of shares to be
redeemed from such holder, the Redemption Date, the Redemption Price, the place
at which payment may be obtained and calling upon such holder to surrender to
the Corporation, in the manner and at the place designated, his certificate or
certificates representing the shares to be redeemed (the "REDEMPTION NOTICE").
On or after each Redemption Date, each holder of Series A Preferred shall
surrender to the Corporation the certificate or certificates representing such
shares, in the manner and at the place designated in the Redemption Notice, and
thereupon the Redemption Price for such shares shall be payable to the order of
the person whose name appears on such certificate or certificates as the owner
thereof and each surrendered certificate shall be canceled.  Nothing herein
shall be deemed to prevent a holder of Series A Preferred from converting all
or part of such holder's Series A Preferred into Common Stock in accordance
with the terms of Section 4(a) hereof at any time prior to the date five (5)
days before each Redemption Date, in which case the provisions of this Section
3 shall not apply to any shares so converted; provided, however that shares so
converted shall be deemed to have been redeemed in the year of conversion,
solely for purposes of determining the Corporation's compliance with the
preceding paragraph.

                                  From and after each Redemption Date, unless
there shall have been a default in payment of the Redemption Price, all rights
of the holders of shares of Series A Preferred so redeemed shall cease with
respect to such shares (except the right to receive the Redemption Price
without interest upon surrender of the shareholder's certificate or
certificates), and such shares shall not thereafter be transferred on the books
of the Corporation or be deemed to be outstanding for any purpose whatsoever.
If the funds of the Corporation legally available for redemption of shares of
Series A Preferred on any Redemption Date are insufficient to redeem the total
number of shares of Series A Preferred required to be redeemed on such
Redemption Date, those funds which are legally available for redemption shall
be used to redeem, on a pro rata basis, the maximum possible number of the
shares of Series A Preferred required to be redeemed on such Redemption Date.
The shares of Series A Preferred not redeemed on a Redemption Date shall remain
outstanding and remain entitled to all the rights and preferences provided
herein, including the rights of conversion set forth in Section 4 hereof.  At
any time thereafter when additional funds 





                                     -5-
   6
of the Corporation are legally available for the redemption of shares of Series
A Preferred, such funds will immediately be used to redeem, on a pro rata
basis, the balance of the shares which the Corporation was obliged to redeem on
such Redemption Date, but which were not redeemed.

                 4.       Conversion.  The holders of Series A Preferred shall
have conversion rights as follows (the "CONVERSION RIGHTS"):

                          (a)     Optional Conversion.  Each share of Series A
Preferred 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 the Corporation
or any transfer agent for the Series A Preferred, into that number of
fully-paid and non-assessable shares of Common Stock that is equal to $1.00
divided by the Conversion Price determined as hereinafter provided, in effect
at the time of conversion.  The price at which shares of Common Stock shall be
deliverable upon conversion of the Series A Preferred, without the payment of
any additional consideration by the holders thereof, (the "CONVERSION PRICE")
shall initially be $1.00 per share of Common Stock, and shall be subject to
adjustment as provided herein.

                          (b)     Automatic Conversion.  Each share of Series A
Preferred shall automatically be converted into shares of Common Stock at the
then effective Conversion Price as follows:

                                    (i)    Initial Public Offering.  Upon the
closing ("CLOSING") of a firm commitment underwritten public offering pursuant
to an effective registration statement under the Securities Act of 1933, as
amended (the "SECURITIES ACT"), covering the offer and sale of Common Stock of
the Corporation to the public at an offering price to the public of at least
Five Dollars ($5.00) per share (as adjusted for any Recapitalization) and in
which the aggregate gross proceeds received by the Corporation (net of
underwriting discounts) equal or exceed ten million dollars ($10,000,000) (an
"IPO").  In the event of the Closing of an IPO, the person(s) entitled to
receive the Common Stock issuable upon such conversion of the Series A
Preferred shall not be deemed to have converted that Preferred Stock until
immediately prior to the Closing.

                                   (ii)    Two-Thirds Percent Vote.  Upon the
affirmative election of the holders of not less than two-thirds of the then
outstanding shares of Series A Preferred.  In the event of such an election,
the person(s) entitled to receive shares of Common Stock issuable upon such
conversion of the Series A Preferred shall not be deemed to have converted that
Series A Preferred until the election (duly approved by not less than
two-thirds of the Series A Preferred then outstanding) is received by the
Corporation.

                         (c)      Mechanics of Conversion.

                                    (i)    No fractional shares of Common Stock
shall be issued upon conversion of Series A Preferred.  In lieu of any
fractional shares to which the holder would otherwise be entitled, the
Corporation at its election shall either pay cash equal to such fraction





                                      -6-
   7
multiplied by the then fair market value of a share of Common Stock, as
determined by the Board, or issue one whole share of Common Stock for each
fraction of a share outstanding, after aggregating all fractional shares held
by each stockholder.

                                   (ii)    Before any holder of Series A
Preferred shall be entitled to convert the same into full shares of Common
Stock pursuant to Section 4(a) above, such holder shall surrender the
certificate or certificates therefor, duly endorsed, at the office of the
Corporation or of any transfer agent for the Series A Preferred, and shall give
written notice to the Corporation at such office that such holder elects to
convert the same.  In the event of an automatic conversion pursuant to
paragraph 4(b) above, the outstanding shares of Series A Preferred shall be
converted automatically without any further action by the holders of such
shares and whether or not the certificates representing such shares are
surrendered to the Corporation or its transfer agent; provided, however, that
the Corporation shall not be obligated to issue certificates evidencing the
shares of Common Stock issuable upon such automatic conversion unless either
the certificates evidencing such shares of Series A Preferred are delivered to
the Corporation or its transfer agent as provided above, or the holder notifies
the Corporation or its transfer agent that such certificates have been lost,
stolen or destroyed and delivers to the Corporation a fully executed agreement
satisfactory to the Corporation to indemnify the Corporation from any loss
incurred by it in connection with such certificates.

         The Corporation shall, as soon as practicable after such delivery
issue and deliver at such office to such holder of Series A Preferred, a
certificate or certificates for the number of shares of Common Stock to which
such holder shall be entitled as aforesaid and a check payable to the holder in
the amount of any cash amounts payable as the result of a conversion into
fractional shares of Common Stock, if applicable.  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 Series A Preferred 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 on such date.

                          (iii)   In the event of the automatic conversion of
shares of Series A Preferred in accordance with Section 4(b) or any voluntary
conversion pursuant to Section 4(a) that occurs within ninety (90) days
immediately prior to the effective date of any automatic conversion, any and
all rights held by the holders of such converted shares of Series A Preferred
to receive any accrued but unpaid dividends in respect of such shares shall
terminate and be of no effect as of the date of such conversion.

                         (d)     Adjustments to Conversion Price for Certain 
Issues.

                                    (i)    Adjustments for Subdivisions, Stock
Dividends, or Combinations of Common.  In the event the outstanding shares of
Common Stock shall be subdivided (by stock split, stock dividend or otherwise)
into a greater number of shares of Common Stock and the outstanding shares of
Series A Preferred are not identically subdivided, the Conversion Price in
effect immediately prior to such subdivision shall, concurrently with the
effectiveness of such





                                      -7-
   8
subdivision, be proportionately decreased.  In the event the outstanding shares
of Common Stock shall be combined (by reclassification, reverse stock split or
otherwise) into a lesser number of shares of Common Stock and the outstanding
shares of Series A Preferred are not identically combined, the Conversion Price
in effect immediately prior to such combination shall, concurrently with the
effectiveness of such combination, be proportionately increased.

                                   (ii)    Adjustments for Other Distributions.
In the event the Corporation at any time or from time to time makes or fixes a
record date for the determination of holders of Common Stock entitled to
receive any distribution payable in securities of the Corporation other than
shares of Common Stock and other than as otherwise adjusted in this Section 4,
then and in each such event provision shall be made so that the holders of
Series A Preferred shall receive upon conversion thereof, in addition to the
number of shares of Common Stock receivable thereupon, the amount of securities
of the Corporation which they would have received had their Series A Preferred
been converted into Common Stock on the date of such event and had they
thereafter, during the period from the date of such event to and including the
date of conversion, retained such securities receivable by them as aforesaid
during such period, subject to all other adjustments called for during such
period under this Section 4 with respect to the rights of the holders of the
Series A Preferred.

                                  (iii)    Adjustments for Reclassification,
Exchange and Substitution.  If the Common Stock issuable upon conversion of the
Series A Preferred shall be changed into the same or a different number of
shares of any other class or classes of stock, whether by capital
reorganization, reclassification or otherwise (other than a subdivision or
combination of shares provided for above), the Conversion Price  then in effect
shall, concurrently with the effectiveness of such reorganization or
reclassification, be proportionately adjusted such that the Series A Preferred
shall be convertible into, in lieu of the number of shares of Common Stock
which the holders would otherwise have been entitled to receive, a number of
shares of such other class or classes of stock that would have been subject to
receipt by the holders of the number of shares of Common Stock issuable upon
conversion of the Series A Preferred immediately before that change.

                                   (iv)    Reorganization, Mergers,
Consolidations or Sales of Assets.  If at any time or from time to time there
shall be a capital reorganization of the Common Stock (other than a
subdivision, combination, reclassification, or exchange of shares provided for
elsewhere in this Section 4) or a merger or consolidation of this Corporation
with or into another corporation, or the sale of all or substantially all of
this Corporation's properties and assets to any other person (other than a
merger, consolidation or sale deemed to be a Liquidation as provided for in
Section 2(c)(i)), then, as a part of such reorganization, merger,
consolidation, or sale, provision shall be made so that the holders of the
Series A Preferred shall thereafter be entitled to receive upon conversion of
the Series A Preferred, the number of shares of stock or other securities or
property of this Corporation, or of the successor corporation resulting from
such merger or consolidation or sale, to which a holder of Common Stock
deliverable upon conversion of the Series A Preferred would have been entitled
to upon such capital reorganization, merger, consolidation, or sale.  In any
such case, appropriate adjustment shall be made in the application





                                      -8-
   9
of the provisions of this Section 4 with respect to the rights of the holders
of the Series A Preferred after such reorganization, merger, consolidation, or
sale 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) shall be applicable after that event as
nearly equivalent as may be practicable.

                          (e)     No Impairment.  The Corporation will not, by
amendment of its Certificate of Incorporation or through any reorganization,
transfer of assets, 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 the 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 against impairment.

                          (f)     Certificate as to Adjustments.  Upon the
occurrence of each adjustment or readjustment of the Conversion Price pursuant
to this Section 4, the Corporation at its expense shall promptly compute such
adjustment or readjustment in accordance with the terms hereof and furnish to
each holder of Series A Preferred a certificate setting forth such adjustment
or readjustment and showing in detail the facts upon which such adjustment or
readjustment is based.  The Corporation shall, upon the written request at any
time of any holder of Series A Preferred, furnish or cause to be furnished to
such holder a like certificate setting forth (i) such adjustments and
readjustments, (ii) the Conversion Price and (iii) the number of shares of
Common Stock and the amount, if any, of other property which at the time would
be received upon the conversion of Series A Preferred.

                          (g)     Notices of Record Date.  In the event that
the Corporation shall propose at any time:

                                    (i)    to declare any dividend or
distribution upon its Common Stock, whether in cash, property, stock or other
securities, whether or not a regular cash dividend and whether or not out of
earnings or earned surplus;

                                   (ii)    to offer for subscription pro rata
to the holders of any class or series of its stock any additional shares of
stock of any class or series or other rights;

                                  (iii)    to effect any reclassification or
recapitalization of its Common Stock outstanding involving a change in the
Common Stock; or

                                   (iv)    to merge with or into any other
corporation, or sell, lease or convey all or substantially all its property or
business, or to liquidate, dissolve or wind up; then, in connection with each
such event, the Corporation shall send to the holders of the Series A Preferred
at least twenty (20) business days' prior written notice of the date on which a
record shall be taken for such dividend, distribution or subscription rights
(and specifying the date on which the holders of Common Stock shall be entitled
thereto) or for determining rights to vote in respect of the matters referred
to in (iii) and (iv) of this clause (g).

         Each such written notice shall be given by first class mail, postage
prepaid, addressed to the holders of Series A Preferred at the address for each
such holder as shown on the books of the Corporation.

                          (h)     Reservation of Stock Issuable Upon
Conversion.  The 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, such number
of its shares of Common Stock as shall from time to time be sufficient to
effect the conversion of all then outstanding shares of the Series A Preferred;
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, the 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 purpose.

                 5.       Voting Rights of Series A Preferred.   The holder of
each share of Series A Preferred shall have the right to one vote for each full
share of Common Stock into which each such share of Series A Preferred could
then be converted pursuant to Section 4(a).  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 the 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.

                 6.       Special Voting Rights of Series A Preferred.

                          (a)     The Corporation shall not, without first
obtaining the approval (by vote or written consent, as provided by law) of the
holders of at least two-thirds of the then outstanding shares of Series A
Preferred (voting in accordance with Section 5):

                                    (i)    create any new class or series of
stock having a preference over, or being on parity with, the Series A Preferred
with respect to dividends, redemption or upon liquidation or otherwise; or

                                   (ii)    sell, lease, convey or otherwise
dispose of all or substantially all of its property or business; or

                                  (iii)    amend or repeal any provision of, or
add any provision to, the Certificate of Incorporation if such action would
adversely alter or change the rights, preferences, privileges or powers of the
Series A Preferred; or

                                   (iv)    increase the authorized number of
shares of its Preferred Stock or Common Stock; or

                                    (v)    undertake any transaction or series
of transactions involving a reorganization, consolidation or merger as a result
of which the holders of the voting stock of the Corporation prior thereto hold
less than 50% of the voting stock of the surviving or successor corporation or
entity; or

                                   (vi)    pay or declare any dividend other
than in Common Stock to the holders of Common Stock; or

                                  (vii)    repurchase or otherwise acquire,
directly or indirectly, through subsidiaries or otherwise, its securities,
other than repurchases from employees of, or consultants to, the Company upon
termination of employment or consultancy.

                 7.       Status of Converted or Redeemed Stock.  In the event
any shares of Series A Preferred shall be redeemed or converted pursuant to
Sections 3 or 4 hereof, respectively, the shares so redeemed or converted shall
be canceled and shall not be reissuable by the Corporation, and the Certificate
of Incorporation shall be appropriately amended to effect the corresponding
reduction in this Corporation's authorized capital stock.

         (C)     Rights of Common Stock.  The rights and other matters relating
to the Common Stock are, unless otherwise expressly provided in this
Certificate of Incorporation, as set forth in this Article IV(C).

                 1.       Voting Rights.  Except as otherwise expressly
provided in this Certificate of Incorporation or as required by applicable law
which cannot be superseded by the provisions of this Certificate of
Incorporation, the holders of the outstanding shares of Common Stock shall
possess voting power for the election of directors and for all other purposes,
each holder of record of shares of Common Stock being entitled to one vote for
each share of Common Stock standing in such holder's name on the books of the
Corporation.

                 2.       Residual Rights.  All rights accruing to the
outstanding shares of the Corporation not expressly provided for to the
contrary herein shall be vested in the Common Stock.

Bylaws of the Corporation.

                                  ARTICLE VII

         Until the closing of an IPO, at the election of directors of the
Corporation, each holder of stock of any class of series shall be entitled to
as many votes as shall equal the number of votes which (except for this
provision as to cumulative voting) he or she would be entitled to cast for the
election of directors with respect to his or her shares of stock multiplied by
the number of directors to be elected by him or her, and he or she may cast all
of such votes for a single director or may distribute them among the number to
be voted for, or for any two or more of them as he or she may see fit, so long
as the name of the nominee for director shall have been placed in nomination
prior to the voting and the stockholder, or any other holder of the same class
or series of stock, has given notice at the meeting prior to the voting of the
intention to cumulate votes.  This Article VII shall terminate and be of no
legal effect upon the Closing of an IPO.

                                  ARTICLE VIII

         To the fullest extent permitted by the Delaware General Corporation
Law, as the same now exists or may hereafter be amended in a manner more

administrative or investigative, by reason of the fact that he or she is or was
