           B. A statement of the rights, preferences, privileges and
restrictions granted to or imposed upon the Series A, B, C, D, E, F, G, H and I
Preferred Stock and the holders thereof is as follows:

               1. Seniority. For purposes of these Articles of Incorporation,
                  ---------
the series of preferred stock shall rank in seniority, from most senior to most
junior, as follows: Series I Stock, Series H Stock, Series G Stock, Series F
Stock, Series E Stock, Series D Stock, Series C Stock, Series B Stock and Series
A Stock.

               2. Dividends. The holders of shares of Series A, B, C, D, E, F,
                  ---------
G, H and I Preferred Stock shall be entitled to receive cash dividends, if, when
and as declared by the Board of Directors. Any dividends that may be declared
with respect to shares of Series A, B, C, D, E, F, G, H and I Preferred Stock
but are not so declared shall be non-cumulative. The holders of shares of Series
A, B, C, D, E, F, G, H and I Preferred Stock shall be entitled to no dividends
with respect to such Preferred Stock other than as stated in this Paragraph 2.
Declared but unpaid dividends shall be accrued but shall not bear interest. No
dividend or distribution whatsoever shall be declared or paid at any time on the
Common Stock or any junior series of Preferred Stock unless a dividend shall be
simultaneously paid on each outstanding share of each series of Preferred Stock
senior thereto in an amount which is equal to or greater than the dividend or
distribution proposed to be declared or paid on each share of Common Stock or
junior series of Preferred Stock (on an as converted to Common Stock basis)
multiplied by the number of shares of Common Stock into which each share of such
series of Preferred Stock is then convertible under Paragraph 5 hereof. For
purposes of the preceding sentence, any dividend or distribution declared or
paid on Series A or Series B Preferred Stock or any securities issued directly
or indirectly with respect to or in exchange for Common Stock shall be deemed to
be declared or paid on the Common Stock. No dividends shall be paid that would
reduce the Corporation's shareholders' equity to less than the aggregate
liquidation preference of all shares of Preferred Stock then outstanding.

           After payment of the preferred dividends to the other series of
Preferred Stock, the holders of outstanding Series A and B Stock shall be
entitled to receive, in any fiscal year, when and as declared by the Board of
Directors, out of any assets at the time legally available therefor, dividends
at the rate of $.006 per share of Series A Stock and $.06 per share of Series B
Stock per annum, before any dividend is paid on Common Stock.  Such dividend may
be payable quarterly or otherwise as the Board of Directors may from time to
time determine.  Dividends may be declared and paid upon Common Stock in any
fiscal year of the Corporation only if

                                       2
<PAGE>

dividends shall have been paid to or declared and set apart upon all shares of
Series A and B Stock at such annual rate for each quarter of such fiscal year of

the Nasdaq National Market, the value shall be deemed to be the average of the
closing prices of the securities on such exchange or system over the twenty (20)
day period ending three (3) days prior to the closing;

notice of any material changes. The transaction shall in no event take place
sooner than twenty (20) days after the Corporation has given the first notice
provided for herein or sooner than ten (10) days after the Corporation has given
notice of any material changes provided for herein; provided, however, that
following notice to all holders of Preferred Stock that are entitled to notice,

5(c) hereof, the outstanding shares of Series A, B, C, D, E, F, G, H and I
Preferred Stock 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, that
the Corporation shall not be obligated to issue to any such holder certificates
evidencing the shares of Common Stock issuable upon such conversion unless
certificates evidencing the shares of Series A, B, C, D, E, F, G, H and I
Preferred Stock or an appropriate indemnity bond are delivered to the
Corporation or any transfer agent of the Corporation. The holder of any shares
of Series A, B, C, D, E, F, G, H and I Preferred Stock may exercise the
conversion right specified in Subparagraph 5(a) hereof as to any part thereof by

                                       14
<PAGE>

surrendering to the Corporation or any transfer agent of the Corporation the
certificate or certificates representing the shares to be converted, accompanied
by written notice stating that the holder elects to convert all or a specified
portion of the shares represented thereby. Conversion of such Preferred Stock
shall be deemed to have been effected on the date on which an event specified
with respect to such Preferred Stock in Subparagraph 5(b) or 5(c) hereof shall
have occurred or on the date when delivery of notice of an election to convert
and certificates representing such shares is made, as the case may be, and such
date is referred to herein with respect to such series of Preferred Stock as the
"Conversion Date" for such series. Subject to the provisions of Subparagraph
5(g)(v) hereof, as promptly as practicable after the Conversion Date (and after
surrender of the certificate or certificates representing shares of such
Preferred Stock to the Corporation or any transfer agent of the Corporation in
the case of conversions pursuant to Subparagraph 5(b) or 5(c) hereof) the
Corporation shall issue and deliver to such holder a certificate or certificates
for the number of full shares of Common Stock to which such holder is entitled
and a check or cash with respect to any fractional interest in a share of Common
Stock as provided in Subparagraph 5(e) hereof and any dividends on the such
Preferred Stock which such holder is entitled to receive, but has not yet
received. Subject to the provisions of Subparagraph 5(f)(v) hereof, the person
in whose name the certificate or certificates for Common Stock are to be issued
shall be deemed to have become a holder of record of such Common Stock on the
applicable Conversion Date. Upon conversion of only a portion of the number of
shares covered by a certificate representing shares of Preferred Stock
surrendered for conversion (in the case of conversion pursuant to Subparagraph
5(a) hereof), the Corporation shall issue and deliver to the holder of the
certificate so surrendered for conversion, at the expense of the Corporation, a
new certificate covering the number of shares of Preferred Stock representing
the unconverted portion of the certificate so surrendered.

               (f) Fractional Shares. No fractional shares of Common Stock or
                   -----------------
scrip shall be issued upon conversion of shares of Preferred Stock. If more than
one share of Preferred Stock shall be surrendered for conversion at any one time
by the same holder, the number of full shares of Common Stock issuable upon
conversion thereof shall be computed on the basis of the aggregate number of
shares of Preferred Stock so surrendered. Instead of any fractional shares of
Common Stock which would otherwise be issuable upon conversion of any shares of
Preferred Stock, the Corporation shall pay a cash adjustment in respect of such
fractional interest in an amount equal to that fractional interest of the then
current market price, as determined reasonably and in good faith by the Board of
Directors of the Corporation, irrespective of any accounting treatment.

               (g) Conversion Price Adjustments for the Preferred Stock. Each of
                   ----------------------------------------------------
the Series A, B, C-1, C-2, C-3, D, E, F, G, H-1, H-2 and I Conversion Price, as
applicable, shall be subject to adjustment from time to time as follows:

                         (i) Stock Dividends; Stock Splits. If the number of
                             -----------------------------
shares of Common Stock outstanding at any time after the date of issuance of a
series of Preferred Stock is increased by a stock dividend payable in shares of
Common Stock or by a subdivision or split-up of shares of Common Stock, then,
immediately after the record date fixed for the determination of holders of
Common Stock entitled to receive such stock dividend or the effective date of
such subdivision or split-up, as the case may be, the Conversion Price for each
series of Preferred Stock shall be automatically reduced so that the holder of
any shares of such

                                       15
<PAGE>

series of Preferred Stock thereafter converted shall be entitled to receive the
number of shares of Common Stock of the Corporation which he would have owned
immediately following such action had such shares of Preferred Stock been
converted immediately prior thereto.

                         (ii) Combination of Stock. If the number of shares of
                              --------------------
Common Stock outstanding at any time after the date of issuance of a series of
Preferred Stock is decreased by a combination of the outstanding shares of
Common Stock, then, immediately after the effective date of such combination,
the Conversion Price for each series of Preferred Stock shall be automatically
increased so that the holder of any shares of Preferred Stock thereafter
converted shall be entitled to receive the number of shares of Common Stock of
the Corporation which he would have owned immediately following such action had
such shares of Preferred Stock been converted immediately prior thereto.

                         (iii) Reorganizations, Etc. In case of any capital
                               ---------------------
reorganization of the Corporation, or of any reclassification of the Common
Stock, or in case of the merger of the Corporation with or into any other
Person, the exchange of shares of Common Stock for securities of another Person,
or of the sale, lease or other transfer of all or substantially all of the
assets of the Corporation to any other Person (other than reorganizations,
reclassifications, mergers, exchanges, sales, leases or other transfers provided
for in Section 3 hereof), each share of Preferred Stock shall, after such
capital reorganization, reclassification, merger, exchange, sale, lease or other
transfer, be convertible into the number of shares of stock or other securities
or property to which the Common Stock issuable (at the time of such capital
reorganization, reclassification, merger, exchange, sale, lease or other
transfer) upon conversion of such share of Preferred Stock would have been
entitled upon such capital reorganization, reclassification, merger, exchange,
sale, lease or other transfer; and in any such case, if necessary, the
provisions set forth herein with respect to the rights and interests thereafter
of the holders of each series of Preferred Stock shall be automatically adjusted
so as to be applicable, as nearly as may reasonably be possible, to any shares
of stock or other securities or property thereafter deliverable on the
conversion of the shares of each series of Preferred Stock. The subdivision or
combination of shares of Common Stock issuable upon conversion of shares of
Preferred Stock at any time outstanding into a greater or lesser number of
shares of Common Stock (whether with or without par value) shall not be deemed
to be a reclassification of the Common Stock of the Corporation for the purposes
of this clause (iii).

                         (iv) Rounding of Calculations, Minimum Adjustment. All
                              --------------------------------------------
calculations under this Subparagraph 5(g) shall be made by rounding upward to
the nearest cent or rounding downward to the nearest one hundredth (1/100th) of
a share, as the case may be. Any provision of this Paragraph 5 to the contrary
notwithstanding and except for immediately prior to the time shares of Preferred
Stock convert into Common Stock (for which this sentence shall not apply), no
adjustment in the Conversion Price of any series of Preferred Stock shall be
made if the amount of such adjustment would be less than one percent (1%) of the
applicable Conversion Price of such series of Preferred Stock then in effect,
but any such amount shall be carried forward and an adjustment with respect
thereto shall be made at the time of and together with any subsequent adjustment
which, together with such amount and any other amount or amounts so carried

                         (v) Timing of Issuance of Additional Common Stock Upon
                             --------------------------------------------------
Certain Adjustments. In any case in which the provisions of this Subparagraph
-------------------
5(g) shall require that an adjustment shall become effective immediately after
the record date for an event, the Corporation may defer until the occurrence of
such event (A) issuing to the holder of any shares of Preferred Stock converted
after such record date and before the occurrence of such event the additional
shares of Common Stock issuable upon such conversion by reason of the adjustment
required by such event over and above the shares of Common Stock issuable upon
such conversion before giving effect to such adjustment and (B) paying to such
holder any amount of cash in lieu of a fractional share of Common Stock pursuant
to Subparagraph (f) of this Paragraph 5; provided, that the Corporation upon
request shall deliver to such holder an appropriate instrument evidencing such
holder's right to receive such additional shares, and such cash, upon the
occurrence of the event requiring such adjustment.

                         (vi) Stock Issued at a Price Less than the Applicable
                              ------------------------------------------------
Series C-1, C-2, C-3, D, E, F, G, H-1, H-2 and I Conversion Price.
-----------------------------------------------------------------

                             (A) In the event that after the file date of these
Amended and Restated Articles of Incorporation this Corporation shall issue,
sell or enter into any contract to issue or sell any stock other than Series G
or H-1 Excluded Stock (as defined in Subparagraph 5(g)(vii)(A) hereof) ("Series
G Additional Stock" or "Series H-1 Additional Stock") for a consideration per
share less than the Adjusted Series G or H-1 Conversion Price, as the case may
be, (determined on a Common Stock equivalent basis if securities are other than
Common Stock) in effect on the date of and immediately prior to such issue, sale
or contract date then and in such event, the Adjusted Series G or H-1 Conversion
Price, as the case may be, shall be reduced, concurrently with such issue, sale
or contract, to a price (calculated to the nearest cent) determined by dividing
the aggregate consideration received by the Corporation for the total number of
Series G or H-1 Additional Stock, as the case may be (determined on a Common
Stock equivalent basis if securities are other than Common Stock) so issued,
sold or contracted for by the total number of Series G or H-1 Additional Stock,
as the case may be, (determined on a Common Stock equivalent basis if securities
are other than Common Stock) so issued, sold or contracted for.

                             (B) If the Corporation shall issue, sell or enter
into any contract to issue or sell any stock other than Excluded Stock (as
defined in subparagraph 5(g)(vii)(B) hereof) ("Additional Stock") without
consideration or for consideration per share (determined on a Common Stock
equivalent basis if the securities are other than Common Stock) for less than
the Adjusted Series C, D, E, F, H-2 or I Conversion Price in effect on the date
of and immediately prior to such issue, sale or contract date (taking into
account all prior adjustments thereto pursuant to Subparagraph 5(g) hereof),
then the Series C-1, C-2, C-3, D, E, F, H-2 or I Conversion Price, as
applicable, shall, concurrently with such issue, sale or contract, be reduced to
a price per share determined by multiplying the Series C-1, C-2, C-3, D, E, F,
H-2 or I Conversion Price, as applicable, by a fraction (i) the numerator of
whichshall be (A) the number of shares of Common Stock deemed outstanding (as
definedin the following sentence) immediately

                                       17
<PAGE>


prior to such issuance, sale or contract date, plus (B) the number of shares of
Common Stock which the aggregate consideration received by the Corporation for
the aggregate Additional Stock would purchase at such Adjusted Series C-1, C-2,
C-3, D, E, F, H-2 or I Conversion Price in effect immediately prior to such
issuance of Additional Stock, as applicable, and (ii) the denominator of which
shall be (X) the number of shares of Common Stock deemed outstanding (as defined
in the following sentence) immediately prior to such issuance, sale or contract
date, plus (Y) the total number of shares of Additional Stock (determined on a
Common Stock equivalent basis if securities are other than Common Stock) so
issued, sold or contracted for. For the purposes of the preceding sentence
Common Stock shall mean, (i) all outstanding shares of Common Stock and, (ii)
all shares of Common Stock issuable upon conversion of outstanding shares of
Series A, B, C-1, C-2, C-3, D, E, F, G, H and I Preferred Stock.

                             (C) For purposes of any adjustment of the Series C-
1, C-2, C-3, D, E, F, G, H-1, H-2 or I Conversion Price pursuant to this
Subparagraph 5(g)(vi), (i) the grant, issue or sale of Additional Stock
consisting of the same class of security and warrants to purchase such security
issued or issuable at the same price at two or more closings held within a six-
month period shall be aggregated and shall be treated as one sale of Additional
Stock occurring on the earliest date on which such securities were granted,
issued or sold, and (ii) the grant, issue or sale of Additional Stock consisting
of one or more types of securities in connection with any one financing
transaction shall be aggregated and shall be treated as one sale of Additional
Stock occurring on the earliest date on which such securities were granted,
issued or sold with the purchase price for the sale of such Additional Stock
equal to the aggregate consideration paid or to be paid for such Additional
Stock and the per share security purchase price equal to the quotient of (x) the
aggregate consideration paid or to be paid for such Additional Stock divided by
(y) the aggregate number of shares of Additional Stock (determined on a Common
Stock equivalent basis for securities other than Common Stock) so issued,
granted or sold.

           In addition, for the purposes of any adjustment of the Series C-1, C-
2, C-3, D, E, F, G, H-1, H-2 or I Conversion Price pursuant to this Subparagraph
5(g)(vi), the following provisions shall be applicable:

                             (D) Cash. In the case of the issuance of securities
                                 ----
of the Corporation for cash, the amount of the consideration received by the
Corporation shall be deemed to be the amount of the cash proceeds received by
the Corporation for such securities before deducting therefrom any reasonable
discounts, commissions, taxes or other expenses allowed, paid or incurred by the
Corporation for any underwriting or otherwise in connection with the issuance
and sale thereof.

                             (E) Consideration Other than Cash. In the case of
                                 -----------------------------

terms) for a consideration in whole or in part other than cash, including
securities acquired in exchange therefor (other than securities by their terms
so exchangeable), the consideration other than cash shall be deemed to be the
fair market value thereof as determined reasonably and in good faith by the
Board of Directors of the Corporation, irrespective of any accounting treatment.

                             (F) Options and Convertible Securities. In the case

upon the issuance of such Convertible Securities plus the minimum purchase price
provided in such Convertible Securities for the Common Stock covered thereby;

                                  (2) the aggregate maximum number of shares of
Common Stock deliverable upon conversion of or in exchange for any such
Convertible Securities, or upon the exercise of options, warrants or other
rights to purchase or acquire such Convertible Securities and the subsequent

such securities were issued or such options, warrants or rights were issued and
for a consideration equal to the consideration, if any, received by the
Corporation for any such Convertible Securities and related options, warrants 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
the Corporation upon the conversion or exchange of such Convertible Securities
and the exercise of any related options, warrants or rights (the consideration
in each case to be determined in the manner provided in subclauses (D) and (E)
above);

                                  (3) on any change in the number of shares of
Common Stock deliverable upon exercise of any such Convertible Securities or
conversion of or exchange for such Convertible Securities or any change in the
consideration to be received by the Corporation upon such exercise, conversion
or exchange, including, but not limited to, a change resulting from the anti-
dilution provisions thereof,

<PAGE>

          the applicable Conversion Price as then in effect, to the extent in
          any way affected by or computed using such Convertible Securities,
          shall automatically be readjusted to such Conversion Price as would
          have been obtained had an adjustment been made upon the issuance of
          such Convertible Securities not exercised prior to such change, or
          securities not converted or exchanged prior to such change, upon the
          basis of such change;

                                  (4) if the applicable Conversion Price shall
          have been adjusted upon or after the issuance of any such Convertible
          Securities, no further adjustment of such Conversion Price shall be
          made for the actual issuance of Common Stock upon the exercise
          thereof.

Conversion Price in effect immediately prior to such closing; provided, however,
to the extent that the Adjusted Series F Conversion Price, the Adjusted Series G
or the Adjusted Series H Conversion Price at such time were less than the
Adjusted Series E Conversion Price then in effect, then such Adjusted Series F
Conversion Price, Adjusted Series G or the Adjusted Series H Conversion Price,
as applicable, shall not be adjusted pursuant to this subparagraph.

                   (h) Statement Regarding Adjustments. Whenever a Conversion
                       -------------------------------
Price shall be adjusted as provided in Subparagraph 5(g) hereof, the Corporation
shall as soon as practicable file, at the office of any transfer agent for the
affected series of Preferred Stock and at the principal office of the
Corporation, a certificate showing in detail the facts requiring such adjustment
and the Conversion Price for such series that shall be in effect after such
adjustment, and the Corporation shall also cause a copy of such certificate to
be sent by mail, first class postage prepaid, to each holder of such series of
Preferred Stock at its address appearing on the Corporation's records. Where
appropriate such copy may be given in advance and may be included as part of a
notice required to be mailed under the provisions of Subparagraph 5(i) hereof.

                   (i) Notice to Holders. In the event the Corporation shall
                       -----------------
propose to take any action of the type described in Subparagraphs 5(g)(i)

to take place. Such notice shall also set forth such facts with respect thereto
as shall be reasonably necessary to indicate the effect of such action (to the
extent such effect may be known at the date of such notice) on the Conversion
Price of each series of Preferred Stock and the number, kind or class of shares
or other securities or property which shall be deliverable or purchasable upon
the occurrence of such action or deliverable upon conversion of shares of each
series of Preferred Stock. In the case of any action which would require the

prior to the date so fixed, and in case of all other action, such notice shall
be given at least twenty (20) days prior to the taking of such proposed action.

                   (j) Costs. The Corporation shall pay all documentary, stamp,
                       -----
transfer or other transactional taxes attributable to the issuance or delivery
of shares of Common Stock of the Corporation upon conversion of any shares of
Preferred Stock; provided, that the Corporation shall not be required to pay any
taxes which may be payable in respect of any transfer involved in the issuance
or delivery of any certificate for such shares in a name other than that of the
holder of the Preferred Stock in respect of which such shares are being issued.

                   (k) Reservation of Shares. The Corporation shall reserve at
                       ---------------------
all times, so long as any shares of Preferred Stock remain outstanding or
reserved for issuance upon exercise of outstanding options or warrants, free
from preemptive rights, out of its authorized but unissued shares of Common
Stock, solely for the purpose of effecting the conversion of the shares of
Preferred Stock, sufficient shares of Common Stock to provide for the conversion
of all outstanding shares of Preferred Stock.

                   (l) Approvals. If any shares of Common Stock to be reserved
                       ---------
for the purpose of conversion of shares of Preferred Stock require registration
with or approval of any governmental authority under any Federal or state law
before such shares may be validly issued or delivered upon conversion, then the
Corporation will in good faith and as expeditiously as possible endeavor to
secure such registration or approval, as the case may be. If, and as long as,
any Common Stock into which the shares of Preferred Stock are then convertible
is listed on any national securities exchange, the Corporation will, if
permitted by the rules of such exchanger list and keep listed on such exchange,
upon official notice of issuance, all shares of such Common Stock issuable upon
conversion.

                   (m) Valid Issuance. All shares of Common Stock which may be
                       --------------
issued upon conversion of the shares of Preferred Stock will, upon issuance by
the Corporation, be duly and validly issued, fully paid and nonassessable and
free from all taxes, liens and charges with respect to the issuance thereof.

                    (n) Other Distributions. In the event the Corporation shall
                        -------------------
declare a distribution payable in securities of other persons, evidences of
indebtedness issued by the Corporation or other persons, assets (excluding cash
dividends) or options or rights not referred to in subparagraph 5(g)(i), then,
in each such case for the purpose of this subparagraph 5(n), the holders of the
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 the Corporation into which their shares of Preferred Stock are
convertible as of the record date fixed for the determination of the holders of
Common Stock of the Corporation entitled to receive such distribution.

                   (o) No Impairment. The Corporation will not, by amendment of
                       --------------
its Articles 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 the
Corporation, but will at all times in good faith assist in the carrying out of
all the provisions of this Section 5 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 Preferred Stock against impairment.

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, the Corporation
shall mail to each holder of 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.

                   (q) If all of the outstanding shares of Series C, D, E, F, G,
H and I Preferred Stock shall be converted to Common Stock, then effective on
the Conversion Date of such conversion, all shares of all series of preferred
stock that are junior to the Series C, D, E, F, G, H and I shall automatically
and without further action on the part of any of the holders thereof convert to
Common Stock.

                   (r) Each holder of an outstanding share of Series A, B, C, D,
E, F, G, H or I Preferred Stock shall be deemed to have consented, for purposes
of Sections 502, 503 and 506 of the California Corporations Code to
distributions made by the Corporation in connection with the repurchase of
shares of Common Stock issued to or held by service providers upon termination
of their service relationship pursuant to agreements providing for the right of

                   ----------

                   (a)  Redemption Events.
                        -----------------

                         (i) The holder or holders of not less than a majority
in voting power of the outstanding Series G Preferred Stock may require the
Corporation to redeem the outstanding Series G Preferred Stock in three equal
installments with the first such installment for thirty-three and one-third
percent (33-1/3%) of the then outstanding shares of Series G Preferred Stock

                         (ii) An election pursuant to subparagraph (i) of this
Section B6(a) shall be made by such holders giving the Corporation and each
other holder of Series G Preferred Stock not less than ninety (90) days prior
written notice, which notice shall set forth the date for such redemption.

                   (b) Redemption Date; Redemption Price. Upon the election of
                       ---------------------------------
the holders of at least a majority of the voting power of the outstanding Series
G Preferred Stock to cause the Corporation to redeem the Series G Preferred
Stock pursuant to Article III Section B6(a)(i), all holders of Series G
Preferred Stock shall be deemed to have elected to cause all of the Series G
Preferred Stock to be so redeemed. Any date upon which a redemption shall

                                       23

The aggregate Series G Preferred Redemption Price shall be payable in cash in
immediately available funds to the respective holders of the Series G Preferred
Stock on each Series G Preferred Redemption Date, subject to Sections B6(a) and
B6(c). After an election has been made under this Section B6(b) by the holders
of at least a majority of the voting power of the outstanding Series G Preferred
Stock, until the full Series G Preferred Redemption Price has been paid to such
holders for all shares of Series G Preferred Stock being redeemed: (A) no
dividend whatsoever shall be paid or declared, and no distribution shall be
made, on any capital stock of the Corporation (other than the Series G Preferred
Stock in accordance with Section B6(d)); and (B) no shares of capital stock of
the Corporation (other than the Series G Preferred Stock in accordance with this
Section B6) shall be purchased, redeemed or acquired by the Corporation and no
monies shall be paid into or made available for a sinking fund or set aside or
made available for the purchase, redemption or acquisition thereof.
Notwithstanding the election to cause the Corporation to redeem the Series G
Preferred Stock as provided above, until the full Series G Preferred Redemption
Price has been paid to the holders of the Series G Preferred Stock, the holders
of at least a majority of the voting power of the outstanding Series G Preferred
Stock may rescind such election by providing written notice thereof to the
Corporation.

                   (c) Redemption Prohibited. If, at a Series G Preferred
                       ---------------------
Redemption Date, the Corporation is prohibited under the Corporations Code of
the State of California or other applicable law from redeeming all shares of
Series G Preferred Stock for which redemption is required hereunder, then it
shall redeem such shares on a pro-rata basis among the holders of Series G
Preferred Stock in proportion to the full respective redemption amounts to which
they are entitled hereunder to the extent possible and shall redeem the
remaining shares to be redeemed as soon as the Corporation is not prohibited
from redeeming some or all of such shares under the Corporations Code of the
State of California or other applicable law. The shares of Series G Preferred
Stock not redeemed shall remain outstanding and entitled to all of the rights
and preferences provided in these Articles. In the event that the Corporation
fails to redeem shares for which redemption is required pursuant to this Section
B.6, then during the period from the applicable Series G Preferred Redemption
Date through the date on which such shares are redeemed, the applicable Series G
Preferred Redemption Price of such shares shall bear interest at the per annum
rate of the greater of (i) 7% or (ii) the Citibank, N.A. prime rate published in
the Wall Street Journal on such Series G Preferred Redemption Date, compounded
annually; provided, however, that in no event shall such interest exceed the
          --------  -------
maximum permitted rate of interest under applicable law (the "Maximum Permitted
Rate"). In the event that fulfillment of any provision hereof results in such
rate of interest being in excess of the Maximum Permitted Rate, the obligation
to be fulfilled shall automatically be reduced to the extent required to
eliminate such excess.

                   (d) Dividend After Series G Preferred Redemption Date. From
                       -------------------------------------------------
and after a Series G Preferred Redemption Date, no shares of Series G Preferred
Stock subject to redemption shall be entitled to dividends, if any, as
contemplated by Section A.2; provided,
                             --------

                                       24
<PAGE>

however, that in the event that shares of Series G Preferred Stock are unable to
-------
be redeemed and continue to be outstanding in accordance with Section B.6(c),
such shares shall continue to be entitled to dividends and interest thereon as
provided in Sections A.2 and B.6(c) until the date on which such shares are
actually redeemed by the Corporation.

                   (e) Surrender of Certificates. The Corporation shall give,
                       --------------------------
not less than 15 days prior to nor more than 30 days in advance of the Series G
Preferred Redemption Date, written notice (the "Redemption Notice") to all
holders of the Series G Preferred Stock, which shall require each holder
submitting shares for redemption to surrender to the Corporation on or before
the Series G Preferred Redemption Date, at the place designated in the
Redemption Notice, such holder's certificate or certificates representing the
shares of Series G Preferred Stock to be redeemed. On or prior to the Redemption
Date, each holder of shares of Series G Preferred Stock submitted for redemption
shall surrender the certificate or certificates evidencing such shares to the
Corporation, at the place designated in the Redemption Notice and shall
thereupon be entitled to receive payment of the appropriate Redemption Price by
certified check or wire transfer. In the event the certificate or certificates
are lost, stolen or missing, the holder of Series G Preferred Stock shall
deliver an affidavit or agreement satisfactory to the Corporation to indemnify
the Corporation from any loss incurred by it in connection therewith (an
"Affidavit of Loss") with respect to such certificates at the place set forth in
the Redemption Notice. Each surrendered certificate shall be cancelled and
retired; provided, however, that if the holder has exercised its redemption
         --------  -------
right pursuant to Section B.6(a)(i) or the Corporation is prohibited from
redeeming all shares of Series G Preferred Stock as provided in Section B.6(c),
the holder shall not be required to surrender said certificate(s) to the
Corporation until said holder has received a new stock certificate for those
shares of Series G Preferred Stock not so redeemed.

                7. Retirement of Shares. Shares of Series A, B, C, D, E, F, G, H
                   --------------------

or reacquired in any manner by the Corporation shall be retired and shall not be
reissued.
