willing buyer (not an employee or director of the Corporation at the time of

                  "Current Market Price" shall mean the arithmetic average of
the daily Market Prices per share of Common Stock for the ten consecutive

adjustment to the Conversion Price pursuant to Section 10(c)(1), (2), (3),
(4), (5), (6), or (7), occurs during such ten consecutive Trading Days, the
Market Price for each Trading Day prior to the "ex" date for such other event
shall be adjusted by multiplying such Market Price by the same fraction by
which the Conversion Price is so required to be adjusted as a result of such
other event, (2) if the "ex" date for any event (other than the issuance or
distribution requiring such computation) that requires an adjustment to the
Conversion Price pursuant to Section 10(c)(1), (2), (3), (4), (5), (6), or
(7), occurs on or after the "ex" date for the issuance or distribution
requiring such computation and prior to the day in question, the Market Price
for each Trading Day on and after the "ex" date for such other event shall be
adjusted by multiplying such Market Price by the reciprocal of the fraction
by which the Conversion Price is so required to be adjusted as a result of
such other event, and (3) if the "ex" date for the issuance or distribution
requiring such computation is prior to the day in question, after taking into
account any adjustment required pursuant to clause (1) or (2) of this
proviso, the Market Price for each Trading Day on or after such "ex" date
shall be adjusted by adding thereto the amount of any cash and the fair
market value (as determined by the Board of Directors in a manner consistent
with any determination of such value for purposes of Section 10(c)(4) or (6),
whose determination shall be conclusive and described in a Board Resolution)
of the evidences of indebtedness, shares of capital stock or assets being
distributed applicable to one share of Common Stock as of the close of
business on the day before such "ex" date. For purposes of any computation
under Section 10(c)(6), the Current Market Price of the Common Stock on any
date shall be deemed to be the arithmetic average of the daily Market Prices
per share of Common Stock for such day and the next two succeeding Trading
Days; PROVIDED, HOWEVER, that if the "ex" date for any event (other than the
Tender Offer requiring such computation) that requires an adjustment to the
Conversion Price pursuant to Section 10(c)(1), (2), (3), (4), (5), (6), or
(7), occurs on or after the Expiration Time for the Tender Offer requiring
such computation and prior to the day in question, the Market Price for each
Trading Day on and after the "ex" date for such other event shall be adjusted
by multiplying such Market Price by the reciprocal of the fraction

                                       4

such other event. For purposes of this paragraph, the term "ex" date, (1)

date on which the Common Stock trades, regular way, on such exchange or in
such market after the time at which such subdivision or combination becomes

such market after the Expiration Time of such Tender Offer. Notwithstanding
the foregoing, whenever successive adjustments to the Conversion Price are

intent of Section 10(c) and to avoid unjust or inequitable results as
determined in good faith by the Board of Directors.

consecutive Trading Days ending on and including the Trading Day immediately
prior to such Dividend Payment Date; PROVIDED, HOWEVER, that (1) if the "ex"
date (as hereinafter defined) for any event that requires an adjustment to the
Conversion Price pursuant to Section 10(c)(1), (2), (3), (4), (5), (6), or (7),
occurs during such 20 consecutive Trading Days, the Market Price for each
Trading Day prior to the "ex" date for such other event shall be adjusted by
multiplying such Market Price by the same fraction by which the Conversion Price
is so required to be adjusted as a result of such event, (2) if the "ex" date
for any event that requires an adjustment to the Conversion Price pursuant to
Section 10(c)(1), (2), (3), (4), (5), (6), or (7), occurs on or after the "ex"
date for the issuance or distribution requiring such computation and prior to
the day in question, the Market Price for each Trading Day on and after the "ex"
date for such other event shall be adjusted by multiplying such Market Price by
the reciprocal of the fraction by which the Conversion Price is so required to
be adjusted as a result of such other event, and (3) if the "ex" date for the
issuance or distribution requiring such computation is prior to the day in
question, after taking into account any adjustment required pursuant to clause
(1) or (2) of this proviso, the Market Price for each Trading Day on or after
such "ex" date shall be adjusted by adding thereto the amount of any cash and
the fair market value (as determined by the Board of Directors in a manner
consistent with any determination of such value for purposes of Section 10(c)(4)
or (6), whose determination shall be conclusive and described in a Board
Resolution) of the evidences of indebtedness, shares of capital stock or assets
being distributed applicable to one share of Common Stock as of the close of
business on the day before such "ex" date. For purposes of this paragraph, the
term "ex" date, (1) when used with respect to any issuance or distribution,
means the first date on which the Common Stock trades, regular way, on the
relevant exchange or in the relevant market from which the Market Price was
obtained without the right to receive such issuance or distribution, (2) when
used with respect to any subdivision or combination of shares of Common Stock,
means the first date on which the Common Stock trades, regular way, on such
exchange or in such market after the time at which such subdivision or

which the Common Stock trades, regular way, on such exchange or in such
market after the Expiration Time of such Tender Offer. Notwithstanding the
foregoing, whenever successive adjustments to the Conversion Price are called
for pursuant to Section 10(c), such adjustments shall be made to the Dividend
Price as may be necessary or appropriate to effectuate with respect to the
Dividend Price the intent of Section 10(c) and to avoid unjust or inequitable
results as determined in good faith by the Board of Directors.

                  "Eligible Bank" means a corporation organized or existing

Common Stock were being paid in cash; PROVIDED, HOWEVER, that if shares of
Common Stock for such dividend are not delivered to holders of Series A
Preferred Stock on or prior to the fifth Trading Day after a Dividend Payment
Date, then the Corporation shall not be entitled to pay such dividend in

from the applicable Dividend Payment Date, shall be payable solely in cash.

         a dividend payment would require registration with or approval of any
         governmental authority under any law or regulation, and such
         registration or approval has not been effected or obtained;

                  (3)      the shares of Common Stock to be issued as a dividend
         payment have not been authorized for listing, upon official notice of
         issuance, on any securities exchange or market on which the Common
         Stock is then listed; or have not been approved for quotation if the
         Common Stock is traded in the over-the-counter market;

                  (4)      the Dividend Price of the Common Stock on the
         applicable Dividend Payment Date is less than the par value of one
         share of Common Stock;

                  (5)      the resale of the shares of Common Stock to be issued
         as a dividend would require registration or filing with or approval of
         any governmental authority under any law or regulation, and such
         registration, filing or approval has not been made, effected or
         obtained or is not in effect, or the Registration Statement is
         unavailable for use by the Holder for the resale of the shares;
         provided, however, that with respect to compliance with the securities
         or blue sky laws of the States of the United States, the requirements
         of this clause shall be deemed satisfied if at the applicable time the
         Corporation is in compliance with Section 8(b) of the Subscription
         Agreement; or such shares of Common Stock to be issued as a dividend
         are no longer listed on the NYSE, the AMEX or the Nasdaq; or

                  (6)      a Holder Optional Redemption Event shall have
         occurred and on the applicable Dividend Payment Date any holder of
         shares of Series A Preferred Stock shall


                                      16
<PAGE>

         be entitled to exercise optional redemption rights under Section 11
         hereof by reason of such Holder Optional Redemption Event or shall have
         exercised such optional redemption rights and the Corporation shall not
         have paid the applicable Holder Optional Redemption Price.

                  Shares of Common Stock issued in payment of dividends on
Series A Preferred Stock pursuant to this Section shall be, and for all purposes
shall be deemed to be, validly issued, fully paid and nonassessable shares of
Common Stock of the Corporation; the issuance and delivery thereof is hereby
authorized; and the dispatch in full thereof will be, and for all purposes shall
be deemed to be, payment in full of the cumulative dividends to which holders
are entitled on the applicable Dividend Payment Date.

                  (c)      Neither the Corporation nor any subsidiary of the
Corporation shall redeem, repurchase or otherwise acquire in any one transaction
or series of related transactions any shares of Common Stock (other than in a
Tender Offer to which Section 5(d) is applicable), Junior Dividend Stock or
Junior Liquidation Stock if the number of shares so repurchased, redeemed or
otherwise acquired in such transaction or series of related transactions
(excluding any Option Share Surrender) is more than either (x) 5% of the number
of shares of Common Stock, Junior Dividend Stock or Junior Liquidation Stock, as
the case may be, outstanding immediately prior to such transaction or series of
related transactions or (y) 1% of the number of shares of Common Stock, Junior
Dividend Stock or Junior Liquidation Stock, as the case may be, outstanding
immediately prior to such transaction or series of related transactions if such
transaction or series of related transactions is with any one Person or group of
Affiliated Persons, unless (i) if such redemption, repurchase or acquisition
occurs prior to the end of the Registration Period, at the time thereof the
Registration Statement is effective and available for use by the Holders named
as selling stockholders in the Registration Statement, (ii) no Holder Optional
Redemption Event shall have occurred with respect to which any Holder shall be
entitled to exercise redemption rights under Section 11 or with respect to which
any Holder shall have exercised such rights and the Corporation shall not have
paid, or deposited in accordance with Section 14(c), the Holder Optional
Redemption Price and (iii) the Corporation or such subsidiary offers to purchase
for cash from each Holder at the time of such redemption, repurchase or
acquisition the same percentage of such Holder's shares of Series A Preferred
Stock as the percentage of the number of outstanding shares of Common Stock,
Junior Dividend Stock or Junior Liquidation Stock, as the case may be, to be so
redeemed, repurchased or acquired, at a purchase price per share of Series A
Preferred Stock equal to the sum of (A) the Stated Value PLUS (B) an amount
equal to the accrued and unpaid dividends on such share of Series A Preferred
Stock to the date of repurchase pursuant to this Section 5(c) plus (C) an amount
equal to the Arrearage Interest, if any, on dividends on such share of Series A
Preferred Stock to the date of repurchase pursuant to this Section 5(c).

                  (d)      Neither the Corporation nor any subsidiary of the
Corporation shall (1) make any Tender Offer for outstanding shares of Common
Stock, unless the Corporation contemporaneously therewith makes an offer, or (2)
enter into an agreement regarding a Tender Offer for outstanding shares of
Common Stock by any Person other than the Corporation or any subsidiary of the
Corporation, unless such Person agrees with the Corporation to make an offer, in
either such case to each Holder to purchase for cash at the time of purchase in
such Tender Offer the same percentage of shares of Series A Preferred Stock held
by such Holder as the


                                      17
<PAGE>

percentage of outstanding shares of Common Stock offered to be purchased in
such Tender Offer at a price per share of Series A Preferred Stock equal to
the greater of (i) the sum of (A) the Stated Value PLUS (B) an amount equal
to the accrued and unpaid dividends on such share of Series A Preferred Stock
to the date of purchase PLUS (C) an amount equal to the Arrearage Interest,
if any, on dividends on such share of Series A Preferred Stock to the date of
purchase pursuant to this Section 5(d), and (ii) an amount equal to the
product obtained by multiplying (x) the number of shares of Common Stock
which would, but for the purchase pursuant to such Tender Offer, be issuable
on conversion in accordance with Section 10(a) of one share of Series A
Preferred Stock if a Conversion Notice were given by the Holder of such share
of Series A Preferred Stock on the date of purchase pursuant to such Tender
Offer TIMES (y) the price per share of Common Stock offered in such Tender
Offer.

                  SECTION 6. LIQUIDATION PREFERENCE. In the event of a
liquidation, dissolution, or winding up of the Corporation, whether voluntary or
involuntary, the Holders shall be entitled to receive out of the assets of the
Corporation, whether such assets constitute stated capital or surplus of any
nature, an amount per share of Series A Preferred Stock equal to the Liquidation
Preference, and no more, before any payment shall be made or any assets
distributed to the holders of Junior Liquidation Stock; PROVIDED, HOWEVER, that
such rights shall accrue to the Holders only in the event that the Corporation's
payments with respect to the liquidation preference of the holders of Senior
Liquidation Stock that has been issued in compliance with this Certificate of
Designations are fully met. After the liquidation preferences of such Senior
Liquidation Stock are fully met, the remaining assets of the Corporation
available for distribution shall be distributed ratably among the Holders and
the holders of any Parity Liquidation Stock that has been issued in compliance
with this Certificate of Designations in proportion to the respective
preferential amounts to which each is entitled up to the full extent of such
preferential amounts. After payment in full of the Liquidation Preference of the
shares of the Series A Preferred Stock and the liquidation preference of such
Parity Liquidation Stock that has been issued in compliance with this
Certificate of Designations, the Holders shall not be entitled to any further
participation in any distribution of assets by the Corporation. Neither a
consolidation or merger of the Corporation with another Person nor a sale or
transfer of all or part of the Corporation's assets to any other Person or
Persons in and of itself will be considered a liquidation, dissolution, or
winding up of the Corporation.

                  SECTION 7. MANDATORY REDEMPTION. (a) At the request of any
Holder not less than 60 days prior to the Initial Mandatory Redemption Date, the
Corporation shall give a Mandatory Redemption Notice to such Holder not less
than 30 nor more than 45 Business Days prior to the Initial Mandatory Redemption
Date. The Corporation shall give a Mandatory Redemption Notice to the Holders of
Series A Preferred Stock which has not been redeemed on the Initial Mandatory
Redemption Date not less than 30 nor more than 45 Business Days prior to the
Final Mandatory Redemption Date. On the Initial Mandatory Redemption Date, the
Series A Preferred Stock outstanding on the date the Mandatory Redemption Notice
is sent and held by Holders who have requested redemption shall be redeemed at
the Mandatory Redemption Price. Each Holder of Series A Preferred Stock who has
requested redemption shall have the shares of Series A Preferred Stock it holds
on the date the Mandatory Redemption Notice is sent redeemed. Notwithstanding
the foregoing, the number of shares of Series A Preferred Stock to be redeemed
from each Holder on the Initial Mandatory Redemption Date shall be reduced (and
there shall be a corresponding reduction in the total number of shares redeemed)
by the number


                                      18
<PAGE>

of shares with respect to which such Holder has given a Conversion Notice (x)
on or after the date the Mandatory Redemption Notice is given and (y) prior
to the Initial Mandatory Redemption Date. On the Final Mandatory Redemption
Date, all outstanding Series A Preferred Stock shall be redeemed at the
Mandatory Redemption Price. Any failure or defect in the giving of the
Mandatory Redemption Notice shall not affect the Corporation's obligation to
redeem the shares of Series A Preferred Stock pursuant to this Section 7.

                  (b)      On the Initial Mandatory Redemption Date or the Final
Mandatory Redemption Date (or such later date as a particular Holder shall
surrender to the Corporation the certificate(s) for the shares of Series A
Preferred Stock redeemed), the Corporation shall pay to or upon the order of
each Holder by wire transfer of immediately available funds to such account as
shall be specified for such purpose by such Holder an amount equal to the
Mandatory Redemption Price of all of such Holder's shares of Series A Preferred
Stock to be redeemed on the Initial Mandatory Redemption Date or the Final
Mandatory Redemption Date. A Holder of such shares of Series A Preferred Stock
shall not be entitled to payment of the Mandatory Redemption Price of such
shares of Series A Preferred Stock until such Holder shall have surrendered the
certificate(s) for such shares of Series A Preferred Stock to the Corporation
or, in the case of the loss, theft or destruction of any such certificate, given
indemnity in accordance with Section 14(b).

                  (c)      The Corporation shall not be entitled to give the
Mandatory Redemption Notice with respect to, or to redeem, any shares of Series
A Preferred Stock with respect to which a Conversion Notice has been given
providing for a Conversion Date which is on or prior to the date on which the
Mandatory Redemption Notice is given. If a Mandatory Redemption Notice has been
given, thereafter the proceedings for such Mandatory Redemption shall not affect
the rights of the Holders to convert in accordance with Section 10 any shares of
Series A Preferred Stock called for Mandatory Redemption at any time prior to
the Initial Mandatory Redemption Date or the Final Mandatory Redemption Date. If
on the applicable Initial Mandatory Redemption Date or the Final Mandatory
Redemption Date the Corporation fails to pay the Mandatory Redemption Price of
any outstanding shares of Series A Preferred Stock to be redeemed in full to
such Holder or to deposit the same with an Eligible Bank in accordance with
Section 14(c), such Holder shall be entitled to convert in accordance with
Section 10 the shares of Series A Preferred Stock of such Holder so called for
redemption at any time after the Initial Mandatory Redemption Date or the Final
Mandatory Redemption Date and prior to the date on which the Corporation pays
the Mandatory Redemption Price in full to such Holder for all shares of Series A
Preferred Stock to be redeemed from such Holder (together with any amount due to
such Holder pursuant to Section 14(d)) or so deposits the same (together with
any amount due to such Holder pursuant to Section 14(d)) and gives notice to
such Holder of such deposit and in the case of any such conversion of any share
of Series A Preferred Stock, upon delivery to the converting Holder of the
shares of Common Stock issuable upon such conversion the Corporation shall have
no further liability in respect of the Mandatory Redemption Price of such share
of Series A Preferred Stock other than payment of the amount payable pursuant to
Section 14(d) in respect of the period from the Initial Mandatory Redemption
Date or the Final Mandatory Redemption Date to the Conversion Date for such
conversion.

                  SECTION 8. NO SINKING FUND. The shares of Series A Preferred
Stock shall not be entitled to the benefits of any sinking fund for the
redemption or repurchase of shares of Series A Preferred Stock.

                  SECTION 9. REDEMPTION AT OPTION OF CORPORATION.

                  (a)      CORPORATION REDEMPTION. (1) At any time after the SEC
Effective Date and during the Redemption Period, the Corporation shall have the
right, if a Corporation Redemption Event shall have occurred, on one occasion
only with respect to such Corporation Redemption Event to redeem on the
applicable Corporation Redemption Date all (but not less than all) of the
outstanding shares of Series A Preferred Stock so long as on the date the
Corporation gives the Redemption Notice and at all times thereafter through such
Corporation Redemption Date (w) the Corporation shall be in compliance in all
material respects with its obligations to the Holders (including, without
limitation, its obligations under the Transaction Documents), (x) if such
Redemption Notice is given before the end of the Registration Period, the
Registration Statement shall be effective and available for use by the selling
stockholders named therein and shall reasonably be expected to remain effective
and available for such use for the 30 days following such Corporation Redemption
Date, (y) no Holder Optional Redemption Event shall have occurred (i) with
respect to which any Holder shall be entitled to exercise redemption rights
under Section 11 or (ii) with respect to which any Holder shall have exercised
such rights and the Corporation shall not have paid, or deposited in accordance
with Section 14(c), the Holder Optional Redemption Price and (z) the Corporation
has Net Cash, Cash Equivalent and Eligible Investment Balances which are
sufficient, after taking into account the Corporation's cash requirements during
the period from the date the Redemption Notice is given to the Corporation
Redemption Date, to pay the Corporation Redemption Price of the shares of Series
A Preferred Stock to be redeemed. Any redemption of outstanding shares of Series
A Preferred Stock pursuant to this Section 9(a) shall be made at the applicable
Corporation Redemption Price. In order to exercise its right of redemption under
this Section 9(a), the Corporation shall give a Redemption Notice to the Holders
within five Trading Days after such Corporation Redemption Event occurs and not
less than 30 or more than 35 Trading Days prior to the Corporation Redemption
Date.

                  (2)      On the Corporation Redemption Date (or such later
date as a particular Holder shall surrender to the Corporation the
certificate(s) for the shares of Series A Preferred Stock redeemed), the
Corporation shall pay to or upon the order of each Holder by wire transfer of
immediately available funds to such account as shall be specified for such
purpose by such Holder an amount equal to the Corporation Redemption Price of
all of such Holder's shares of Series A Preferred Stock to be redeemed on the
Corporation Redemption Date. A Holder of such shares of Series A Preferred Stock
shall not be entitled to payment of the Corporation Redemption Price of such
shares of Series A Preferred Stock until such Holder shall have surrendered the
certificate(s) for such shares of Series A Preferred Stock to the Corporation
or, in the case of the loss, theft or destruction of any such certificate, given
indemnity in accordance with Section 14(b).

                  (3)      The Corporation shall not be entitled to give a
Redemption Notice with respect to, or to redeem, any shares of Series A
Preferred Stock with respect to which a Conversion Notice has been given
providing for a Conversion Date which is on or prior to the


                                      20

<PAGE>

date on which a Redemption Notice is given. If a Redemption Notice has been
given, thereafter the proceedings for such redemption shall not affect the
rights of the Holders to convert in accordance with Section 10 any shares of
Series A Preferred Stock called for redemption at any time prior to the
Corporation Redemption Date for such shares. If on the applicable Corporation
Redemption Date the Corporation fails to pay the Corporation Redemption Price
of any outstanding shares of Series A Preferred Stock to be redeemed in full
to such Holder or to deposit the same with an Eligible Bank in accordance
with Section 14(c), such Holder shall be entitled to convert in accordance
with Section 10 the shares of Series A Preferred Stock of such Holder so
called for redemption at any time after such Corporation Redemption Date and
prior to the date on which the Corporation pays the Corporation Redemption
Price in full to such Holder for all shares of Series A Preferred Stock to be
redeemed from such Holder (together with any amount due to such Holder
pursuant to Section 14(d)) or so deposits the same (together with any amount
due to such Holder pursuant to Section 14(d)) and gives notice to such Holder
of such deposit and in the case of any such conversion of any share of Series
A Preferred Stock, upon delivery to the converting Holder of the shares of
Common Stock issuable upon such conversion the Corporation shall have no
further liability in respect of the Corporation Redemption Price of such
share of Series A Preferred Stock, other than payment of the amount payable
pursuant to Section 14(d) in respect of the period from the applicable
Corporation Redemption Date to the Conversion Date for such conversion.

                  (4)      If at any time the Corporation shall have become
entitled to exercise its right to redeem shares of Series A Preferred Stock
pursuant to this Section 9(a) by reason of a Corporation Redemption Event and
the Corporation shall not exercise such right in accordance herewith, then
thereafter the Corporation shall not be entitled to exercise its right to redeem
shares of Series A Preferred Stock pursuant to this Section 9(a) unless a
subsequent Corporation Redemption Event shall have occurred on a date on which
is at least 180 days after the date of such Corporation Redemption Event in
respect of which the Corporation did not exercise its redemption rights.

                  (b)      NO OTHER REDEMPTION AT THE OPTION OF THE CORPORATION.
Except as otherwise specifically provided in Section 9(a), the Corporation shall
not have any right to redeem any shares of Series A Preferred Stock at the
option of the Corporation.

                  SECTION 10. CONVERSION.

                  (a)      RIGHT TO CONVERT. Subject to and upon compliance with
the provisions of this Section 10, each Holder shall have the right, at such
Holder's option, at any time (except that if such Holder shall have exercised
redemption rights under Section 11 or the Corporation shall have exercised its
redemption rights under Section 9, such conversion right shall terminate with
respect to the shares of Series A Preferred Stock to be redeemed at the close of
business on the last Trading Day prior to the date the Corporation pays or
deposits in accordance with Section 14(c) the applicable Holder Optional
Redemption Price, Registration Repurchase Price or Redemption Price unless the
Corporation shall default in payment due upon redemption of any share of Series
A Preferred Stock) to convert the outstanding shares of Series A Preferred Stock
held by such Holder, or from time to time any portion of such shares, plus an
amount equal to accrued and unpaid dividends on such share, into that number of
fully paid and non-assessable shares of Common Stock (as such shares shall then
be constituted) obtained by dividing (1) the

                                       21

<PAGE>

sum of (x) the aggregate Stated Value of all shares of Series A Preferred
Stock being converted by such Holder on the same Conversion Date PLUS (y)
accrued and unpaid dividends on the shares of Series A Preferred Stock being
converted to the applicable Conversion Date PLUS (z) accrued and unpaid
Arrearage Interest, if any, on the amounts referred to in the immediately
preceding clauses (x) and (y) to the applicable Conversion Date BY (2) the
Conversion Price in effect on the applicable Conversion Date, by giving a
Conversion Notice in the manner provided in Section 10(b); PROVIDED, HOWEVER,
that, if at any time any share of Series A Preferred Stock is converted in
whole or in part pursuant to this Section 10(a), the Corporation does not
have available for issuance upon such conversion as authorized and unissued
shares or in its treasury at least the number of shares of Common Stock
required to be issued pursuant hereto, then, at the election of such Holder
made by notice from such Holder to the Corporation, such share of Series A
Convertible Preferred Stock, to the extent that sufficient shares of Common
Stock are not then available for issuance upon conversion, shall be converted
into the right to receive from the Corporation, in lieu of the shares of
Common Stock into which such share of Series A Convertible Preferred Stock
would otherwise be converted and which the Corporation is unable to issue,
payment in an amount equal to the product obtained by multiplying (x) the
number of shares of Common Stock to which the Holder is entitled which the
Corporation is unable to issue TIMES (y) the arithmetic average of the Market
Price for the Common Stock during the five consecutive Trading Days
immediately prior to the applicable Conversion Date. Any such payment shall,
for all purposes of this Certificate of Designations, be deemed to be
satisfaction in full of the Corporation's obligation to issue upon such
conversion shares of Common Stock that are not then available for issuance
upon such conversion. A Holder is not entitled to any rights of a holder of
Common Stock until such Holder has converted one or more shares of Series A
Preferred Stock to Common Stock, and only to the extent any such shares of
Series A Preferred Stock are deemed to have been converted to Common Stock
under this Section 10. For purposes of Sections 10(e) and 10(f), whenever a
provision references the shares of Common Stock into which any share of
Series A Preferred Stock is convertible or the shares of Common Stock
issuable upon conversion of any share of Series A Preferred Stock or words of
similar import, any determination required by such provision shall be made as
if a sufficient number of shares of Common Stock were then available for
issuance upon conversion in full of all outstanding shares of Series A
Preferred Stock.

                  (b)      EXERCISE OF CONVERSION PRIVILEGE; ISSUANCE OF COMMON
STOCK ON CONVERSION; NO ADJUSTMENT FOR INTEREST OR DIVIDENDS. (1) In order to
exercise the conversion privilege with respect to the Series A Preferred Stock,
a Holder shall give a Conversion Notice (or such other notice which is
acceptable to the Corporation) to the Corporation and the Transfer Agent or to
the office or agency designated by the Corporation for such purpose by notice to
the Holders. A Conversion Notice may be given by telephone line facsimile
transmission to the numbers set forth on the form of Conversion Notice.

                  (2)      As promptly as practicable, but in no event later
than three Trading Days, after a Conversion Date, the Corporation shall issue
and shall deliver to the Holder giving a Conversion Notice or such Holder's
designee the number of full shares of Common Stock issuable upon such conversion
of shares of Series A Preferred Stock in accordance with the provisions of this
Section 10 and deliver a check or cash in respect of any fractional interest in
respect of a share of Common Stock arising upon such conversion, as provided in
Section 10(b)(6) and, if applicable, any cash payment required pursuant to the
proviso to the first

                                       22

<PAGE>

sentence of Section 10(a) (which payment, if any, shall be paid no later than
three Trading Days after the applicable Conversion Date). The Holder shall
promptly surrender to the Corporation such Holder's certificates for the
shares of Series A Preferred Stock to be converted.

                  (3)      Each conversion of shares of Series A Preferred Stock
shall be deemed to have been effected on the applicable Conversion Date, and the
person in whose name any certificate or certificates for shares of Common Stock
shall be issuable upon such conversion shall be deemed to have become on such
Conversion Date the holder of record of the shares represented thereby;
PROVIDED, HOWEVER, that if a Conversion Date is a date on which the stock
transfer books of the Corporation shall be closed such conversion shall
constitute the person in whose name the certificates are to be issued as the
record holder thereof for all purposes on the next succeeding day on which such
stock transfer books are open, but such conversion shall be at the Conversion
Price in effect on the applicable Conversion Date. Upon conversion of any shares
of Series A Preferred Stock, the accrued and unpaid dividends on such shares of
Series A Preferred Stock to (but excluding) the applicable Conversion Date shall
be deemed to be paid to the Holder through receipt of such number of shares of
Common Stock issued upon conversion of such shares of Series A Preferred Stock
as shall have an aggregate Current Fair Market Value on the Trading Day
immediately preceding such Conversion Date equal to the amount of such accrued
and unpaid dividends

                  (4)      The Corporation shall notify a Holder of any claim by
the Corporation of manifest error in a Conversion Notice within two Trading Days
after such Holder gives such Conversion Notice and no such claim of error shall
limit or delay performance of the Corporation's obligation to issue upon such
conversion the number of shares of Common Stock which are not in dispute. A
Conversion Notice shall be deemed for all purposes to be in proper form unless
the Corporation notifies the Holder who gives a Conversion Notice by telephone
line facsimile transmission within three Trading Days after the Conversion Date
(which notice from the Corporation shall specify all defects in the Conversion
Notice) and any Conversion Notice containing any such defect shall nonetheless
be effective on the Conversion Date if such Holder promptly undertakes to
correct all such defects. The Corporation shall pay all expenses related to such
issuances (including any stamp taxes or issue taxes); provided that the
Corporation shall not be required to pay any tax which may be payable in respect
of any transfer involved in the issuance and delivery of shares of Common Stock
or other securities or property on conversion of shares of Series A Preferred
Stock in a name other than that of such Holder, and the Corporation shall not be
required to issue or deliver any such shares or other securities or property
unless and until the person or persons requesting the issuance thereof shall
have paid to the Corporation the amount of any such tax or shall have
established to the satisfaction of the Corporation that such tax has been paid.
The converting Holder shall be responsible for the amount of any withholding tax
payable in connection with any conversion of shares of Series A Preferred Stock.

                  (5)      (A) If a Holder shall have given a Conversion Notice
in accordance with the terms of this Certificate of Designations, the
Corporation's obligation to issue and deliver the certificates for Common Stock
shall be absolute and unconditional, irrespective of any action or inaction by
such Holder to enforce the same, any waiver or consent with respect to any
provision hereof, the recovery of any judgment against any person or any action
to enforce the same, any failure or delay in the enforcement of any other
obligation of the Corporation to any Holder, or

                                       23

<PAGE>

any setoff, counterclaim, recoupment, limitation or termination, or any
breach or alleged breach by any Holder or any other person of any obligation
to the Corporation or any violation or alleged violation of law by any Holder
or any other person, and irrespective of any other circumstance which might
otherwise limit such obligation of the Corporation to such Holder in
connection with such conversion; PROVIDED, HOWEVER, that nothing herein shall
limit or prejudice the right of the Corporation to pursue any such claim in
any other manner permitted by applicable law. The occurrence of an event
which requires an adjustment of the Conversion Price as contemplated by
Section 10(c) shall in no way restrict or delay the right of any Holder to
receive certificates for Common Stock upon conversion of shares of Series A
Preferred Stock and the Corporation shall use its best efforts to implement
such adjustment on terms reasonably acceptable to the Majority Holders within
two Trading Days after such occurrence.

                  (B) If the Corporation fails to issue and deliver the shares
of Common Stock to a converting Holder in connection with a particular
conversion of shares of Series A Preferred Stock within three Trading Days after
a Conversion Date, in addition to any other liabilities the Corporation may have
hereunder and under applicable law (x) the Corporation shall pay or reimburse
such Holder on demand for all out-of-pocket expenses, including, without
limitation, reasonable fees and expenses of legal counsel, incurred by the
Holder as a result of such failure, (y) if as a result of such failure such
Holder shall suffer any direct damages or liabilities from such failure
(including, without limitation, margin interest and the cost of purchasing
securities to cover a sale (whether by such Holder or such Holder's securities
broker) or borrowing of shares of Common Stock by such Holder for purposes of
settling any trade involving a sale of shares of Common Stock made by such
Holder during the period beginning on the Issuance Date and ending on the date
the Corporation delivers or causes to be delivered to such Holder such shares of
Common Stock, then the Corporation shall upon demand of such Holder pay to the
Holder an amount equal to the actual direct, out-of-pocket damages and
liabilities suffered by such Holder by reason thereof which such Holder
documents to the reasonable satisfaction of the Corporation, and (z) the Holder
may by written notice (which may be given by mail, courier, personal service or
telephone line facsimile transmission) or oral notice (promptly confirmed in
writing), given at any time prior to delivery to such Holder of the shares of
Common Stock issuable in connection with such exercise of the Holder's
conversion right, rescind such exercise and the Conversion Notice relating
thereto, in which case such Holder shall thereafter be entitled to convert, in
accordance with this Section 10 that portion of such shares of Series A
Preferred Stock as to which such exercise is so rescinded. Notwithstanding the
foregoing, the Corporation shall not be liable to such Holder under clause (y)
of the immediately preceding sentence to the extent the failure of the
Corporation to deliver or to cause to be delivered such shares of Common Stock
results from fire, flood, storm, earthquake, shipwreck, strike, war, acts of
terrorism, crash involving facilities of a common carrier, acts of God, or any
similar event outside the control of the Corporation (it being understood that
the action or failure to act of the Transfer Agent shall not be deemed an event
outside the control of the Corporation except to the extent resulting from fire,
flood, storm, earthquake, shipwreck, strike, war, acts of terrorism, crash
involving facilities of a common carrier, acts of God, the bankruptcy,
liquidation or reorganization of the Transfer Agent under any bankruptcy,
insolvency or other similar law or any similar event outside the control of the
Transfer Agent). A converting Holder shall notify the Corporation in writing (or
by telephone conversation, confirmed in writing) as promptly as practicable
following the third Trading Day after the Conversion Date if such Holder becomes
aware that such shares of Common Stock so

                                       24

<PAGE>

issuable have not been received as provided herein, but any failure so to
give such notice shall not affect the Holder's rights under this Certificate
of Designations or otherwise.

                  (6) No fractional shares of Common Stock shall be issued upon
conversion of any shares of Series A Preferred Stock but, in lieu of any
fraction of a share of Common Stock which would otherwise be issuable in respect
of such conversion, the Corporation shall pay lawful money of the United States
of America for such fractional share, based on a value of one share of Common
Stock being equal to the Market Price of the Common Stock on the applicable
Conversion Date.

                  (7) If a portion of the shares of Series A Preferred Stock
represented by a particular certificate are to be converted, upon surrender of
such certificate to the Corporation, the Corporation shall execute and deliver
to the Holders of such certificate without service charge, a new certificate or
certificates, in such denomination or denominations as requested by such Holder.

                  (c)      ADJUSTMENT OF CONVERSION PRICE. The Conversion Price
shall be adjusted from time to time by the Corporation as follows:

                  (1)      In case the Corporation shall on or after the
Issuance Date pay a dividend or make a distribution to all holders of the
outstanding Common Stock in shares of Common Stock, the Conversion Price in
effect at the opening of business on the date following the date fixed for the
determination of stockholders entitled to receive such dividend or other
distribution shall be reduced by multiplying such Conversion Price by a fraction
of which the numerator shall be the number of shares of Common Stock outstanding
at the close of business on the Record Date fixed for such determination and the
denominator shall be the sum of such number of shares and the total number of
shares constituting such dividend or other distribution, such reduction to
become effective immediately after the opening of business on the day following
such Record Date. If any dividend or distribution of the type described in this
Section 10(c)(1) is declared but not so paid or made, the Conversion Price shall
again be adjusted to the Conversion Price which would then be in effect if such
dividend or distribution had not been declared.

                  (2)      In case the Corporation shall on or after the
Issuance Date issue rights or warrants (other than any rights or warrants
referred to in Section 10(c)(4)) to all holders of its outstanding shares of
Common Stock entitling them to subscribe for or purchase shares of Common Stock
at a price per share less than the Current Market Price on the Record Date fixed
for the determination of stockholders entitled to receive such rights or
warrants, the Conversion Price shall be adjusted so that the same shall equal
the price determined by multiplying the Conversion Price in effect at the
opening of business on the date after such Record Date by a fraction of which
the numerator shall be the number of shares of Common Stock outstanding at the
close of business on the applicable Record Date plus the number of shares which
the aggregate offering price of the total number of shares so offered would
purchase at such Current Market Price, and the denominator shall be the number
of shares of Common Stock outstanding on the close of business on such Record
Date plus the total number of additional shares of Common Stock so offered for
subscription or purchase. Such adjustment shall become effective immediately
after the opening of business on the day following the Record Date fixed for
determination of stockholders entitled to receive such rights or warrants. To
the extent that

                                       25

<PAGE>

shares of Common Stock are not delivered pursuant to such rights or warrants,
upon the expiration or termination of such rights or warrants, the Conversion
Price shall be readjusted to the Conversion Price which would then be in
effect had the adjustments made upon the issuance of such rights or warrants
been made on the basis of delivery of only the number of shares of Common
Stock actually delivered. In the event that such rights or warrants are not
so issued, the Conversion Price shall again be adjusted to be the Conversion
Price which would then be in effect if such Record Date had not been fixed.
In determining whether any rights or warrants entitle the holder to subscribe
for or purchase shares of Common Stock at less than such Current Market
Price, and in determining the aggregate offering price of such shares of
Common Stock, there shall be taken into account any consideration received
for such rights or warrants, the value of such consideration, if other than
cash, to be determined by the Board of Directors.

                  (3)      In case the outstanding shares of Common Stock shall
on or after the Issuance Date be subdivided into a greater number of shares of
Common Stock, the Conversion Price in effect at the opening of business on the
earlier of the day following the day upon which such subdivision becomes
effective and the day on which "ex-" trading of the Common Stock begins with
respect to such subdivision shall be proportionately reduced, and conversely, in
case outstanding shares of Common Stock shall be combined into a smaller number
of shares of Common Stock, the Conversion Price in effect at the opening of
business on the earlier of the day following the day upon which such combination
becomes effective and the day on which "ex-" trading of the Common Stock with
respect to such combination begins shall be proportionately increased, such
reduction or increase, as the case may be, to become effective immediately after
the opening of business on the earlier of the day following the day upon which
such subdivision or combination becomes effective and the day on which "ex-"
trading of the Common Stock begins with respect to such subdivision or
combination.

                  (4)      In case the Corporation shall on or after the
Issuance Date, by dividend or otherwise, distribute to all holders of its Common
Stock shares of any class of capital stock of the Corporation (other than any
dividends or distributions to which Section 10(c)(1) applies) or evidences of
its indebtedness, cash or other assets (including securities, but excluding any
rights or warrants referred to in Section 10(c)(2) and dividends and
distributions paid exclusively in cash and excluding any capital stock,
evidences of indebtedness, cash or assets distributed upon a merger or
consolidation to which Section 10(d) applies) (the foregoing hereinafter in this
Section 10(c)(4) called the "Securities")), then, in each such case, subject to
the second paragraph of this Section 10(c)(4), the Conversion Price shall be
reduced so that the same shall be equal to the price determined by multiplying
the Conversion Price in effect immediately prior to the close of business on the
Record Date with respect to such distribution by a fraction of which the
numerator shall be the Current Market Price on such date less the fair market
value (as determined by the Board of Directors, whose determination shall be
conclusive and described in a Board Resolution) on such date of the portion of
the Securities so distributed applicable to one share of Common Stock and the
denominator shall be such Current Market Price, such reduction to become
effective immediately prior to the opening of business on the day following such
Record Date; PROVIDED, HOWEVER, that in the event the then fair market value (as
so determined) of the portion of the Securities so distributed applicable to one
share of Common Stock is equal to or greater than the Current Market Price on
the Record Date, in lieu of the foregoing adjustment, adequate provision shall
be made so that the Holders shall have the right to receive upon conversion of
shares of Series A Preferred Stock the amount of Securities such Holder

                                       26

<PAGE>

would have received had such Holder converted such Holder's shares of Series
A Preferred Stock immediately prior to such Record Date. In the event that
such dividend or distribution is not so paid or made, the Conversion Price
shall again be adjusted to be the Conversion Price which would then be in
effect if such dividend or distribution had not been declared. If the Board
of Directors determines the fair market value of any distribution for
purposes of this Section 10(c)(4) by reference to the actual or when issued
trading market for any Securities comprising all or part of such
distribution, it must in doing so consider the prices in such market over the
same period used in computing the Current Market Price to the extent possible.

                  Rights or warrants distributed by the Corporation to all
holders of Common Stock entitling the holders thereof to subscribe for or
purchase shares of the Corporation's capital stock (either initially or under
certain circumstances), which rights or warrants, until the occurrence of a
specified event or events (a "Trigger Event"): (i) are deemed to be transferred
with such shares of Common Stock; (ii) are not exercisable; and (iii) are also
issued in respect of future issuances of Common Stock, shall not be deemed to
have been distributed for purposes of this Section 10(c) (and no adjustment to
the Conversion Price under this Section 10(c) will be required) until the
occurrence of the earliest Trigger Event. If any such rights or warrants,
including any such existing rights or warrants distributed prior to the Issuance
Date (including the Preferred Stock Purchase Rights), are subject to Trigger
Events, upon the satisfaction of each of which such rights or warrants shall
become exercisable to purchase different securities, evidences of indebtedness
or other assets, then the occurrence of each such Trigger Event shall be deemed
to be such date of issuance and record date with respect to new rights or
warrants (and a termination or expiration of the existing rights or warrants
without exercise by the holder thereof) (so that, by way of illustration and not
limitation, the dates of issuance of any such rights shall be deemed to be the
dates on which such rights become exercisable to purchase capital stock of the
Corporation, and not the date on which such rights may be issued, or may become
evidenced by separate certificates, if such rights are not then so exercisable).
In addition, in the event of any distribution of rights or warrants, or any
Trigger Event with respect thereto (including the Preferred Stock Purchase
Rights), that was counted for purposes of calculating a distribution amount for
which an adjustment to the Conversion Price under this Section 10(c) was made
(1) in the case of any such rights or warrants which shall all have been
redeemed or repurchased without exercise by any holders thereof, the Conversion
Price shall be readjusted upon such final redemption or repurchase to give
effect to such distribution or Trigger Event, as the case may be, as though it
were a cash distribution, equal to the per share redemption or repurchase price
received by a holder or holders of Common Stock with respect to such rights or
warrants (assuming such holder had retained such rights or warrants), made to
all holders of Common Stock as of the date of such redemption or repurchase, and
(2) in the case of such rights or warrants (including the Preferred Stock
Purchase Rights) which shall have expired or been terminated without exercise by
any holders thereof, the Conversion Price shall be readjusted as if such rights
and warrants had not been issued.

                  For purposes of this Section 10(c)(4) and Sections 10(c)(1)
and (2), any dividend or distribution to which this Section 10(c)(4) is
applicable that also includes shares of Common Stock, or rights or warrants to
subscribe for or purchase shares of Common Stock to which Section 10(c)(2)
applies (or both), shall be deemed instead to be (1) a dividend or distribution
of the evidences of indebtedness, assets, shares of capital stock, rights or
warrants other than such shares of Common Stock or rights or warrants to which
Section 10(c)(2) applies (and any

                                       27

<PAGE>

Conversion Price reduction required by this Section 10(c)(4) with respect to
such dividend or distribution shall then be made) immediately followed by (2)
a dividend or distribution of such shares of Common Stock or such rights or
warrants (and any further Conversion Price reduction required by Sections
10(c)(1) and (2) with respect to such dividend or distribution shall then be
made), except (A) the Record Date of such dividend or distribution shall be
substituted as "the date fixed for the determination of stockholders entitled
to receive such dividend or other distribution", "Record Date fixed for such
determination" and "Record Date" within the meaning of Section 10(c)(1) and
as "the date fixed for the determination of stockholders entitled to receive
such rights or warrants", "the Record Date fixed for the determination of the
stockholders entitled to receive such rights or warrants" and "such Record
Date" within the meaning of Section 10(c)(2) and (B) any shares of Common
Stock included in such dividend or distribution shall not be deemed
"outstanding at the close of business on the Record Date fixed for such
determination" within the meaning of Section 10(c)(1).

                  (5)      In case the Corporation shall on or after the
Issuance Date, by dividend or otherwise, distribute to all holders of its Common
Stock cash (excluding any cash that is distributed upon a merger or
consolidation to which Section 10(d) applies or as part of a distribution
referred to in Section 10(c)(4)) in an aggregate amount that, combined with (1)
the aggregate amount of any other such distributions to all holders of its
Common Stock made exclusively in cash within the 12 months preceding the date of
payment of such distribution, and in respect of which no adjustment pursuant to
this Section 10(c)(5) has been made, and (2) the aggregate of any cash plus the
fair market value (as determined by the Board of Directors, whose determination
shall be conclusive and set forth in a Board Resolution) of consideration
payable in respect of any Tender Offer by the Corporation or any Subsidiary for
all or any portion of the Common Stock concluded within the 12 months preceding
the date of payment of such distribution, and in respect of which no adjustment
pursuant to Section 10(c)(6) has been made, exceeds 10% of the product of (x)
the Current Market Price on the Record Date with respect to such distribution
TIMES (y) the number of shares of Common Stock outstanding on such date, then,
and in each such case, immediately after the close of business on such date,
unless the Corporation elects to reserve such cash for distribution to the
Holders upon the conversion of shares of Series A Preferred Stock (and shall
have made adequate provision) so that the Holders will receive upon such
conversion, in addition to the shares of Common Stock to which the Holders are
entitled, the amount of cash which the Holders would have received if the
Holders had, immediately prior to the Record Date for such distribution of cash,
converted their shares of Series A Preferred Stock into Common Stock, the
Conversion Price shall be reduced so that the same shall equal the price
determined by multiplying the Conversion Price in effect immediately prior to
the close of business on such Record Date by a fraction (i) the numerator of
which shall be equal to the Current Market Price on such Record Date less an
amount equal to the quotient of (x) the excess of such combined amount over such
10% and (y) the number of shares of Common Stock outstanding on such Record Date
and (ii) the denominator of which shall be equal to the Current Market Price on
such Record Date; PROVIDED, HOWEVER, that in the event the portion of the cash
so distributed applicable to one share of Common Stock is equal to or greater
than the Current Market Price of the Common Stock on such Record Date, in lieu
of the foregoing adjustment, adequate provision shall be made so that the
Holders shall have the right to receive upon conversion of shares of Series A
Preferred Stock the amount of cash the Holders would have received had the
Holders converted all of their shares of Series A Preferred Stock immediately
prior to such Record Date. In the event that such dividend or distribution is
not so

                                       28

<PAGE>

paid or made, the Conversion Price shall again be adjusted to be the
Conversion Price which would then be in effect if such dividend or
distribution had not been declared.

                  (6)      In case a Tender Offer on or after the Issuance Date
made by the Corporation or any Subsidiary for all or any portion of the Common
Stock shall expire and such Tender Offer (as amended upon the expiration
thereof) shall require the payment to stockholders (based on the acceptance (up
to any maximum specified in the terms of the Tender Offer) of Purchased Shares
(as defined below)) of an aggregate consideration having a fair market value (as
determined by the Board of Directors, whose determination shall be conclusive
and described in a Board Resolution) that combined together with (1) the
aggregate of the cash plus the fair market value (as determined by the Board of
Directors, whose determination shall be conclusive and described in a Board
Resolution), as of the expiration of such Tender Offer, of consideration payable
in respect of any other Tender Offers, by the Corporation or any Subsidiary for
all or any portion of the Common Stock expiring within the 12 months preceding
the expiration of such Tender Offer and in respect of which no adjustment
pursuant to this Section 10(c)(6) has been made and (2) the aggregate amount of
any distributions to all holders of the Corporation's Common Stock made
exclusively in cash within 12 months preceding the expiration of such Tender
Offer and in respect of which no adjustment pursuant to Section 10(c)(5) has
been made, exceeds 10% of the product of the Current Market Price as of the last
time (the "Expiration Time") tenders could have been made pursuant to such
Tender Offer (as it may be amended) times the number of shares of Common Stock
outstanding (including any tendered shares) at the Expiration Time, then, and in
each such case, immediately prior to the opening of business on the day after
the date of the Expiration Time, the Conversion Price shall be adjusted so that
the same shall equal the price determined by multiplying the Conversion Price in
effect immediately prior to close of business on the date of the Expiration Time
by a fraction of which the numerator shall be the number of shares of Common
Stock outstanding (including any tendered shares) at the Expiration Time
multiplied by the Current Market Price of the Common Stock on the Trading Day
next succeeding the Expiration Time and the denominator shall be the sum of (x)
the fair market value (determined as aforesaid) of the aggregate consideration
payable to stockholders based on the acceptance (up to any maximum specified in
the terms of the Tender Offer) of all shares validly tendered and not withdrawn
as of the Expiration Time (the shares deemed so accepted, up to any such
maximum, being referred to as the "Purchased Shares") and (y) the product of the
number of shares of Common Stock outstanding (less any Purchased Shares) at the
Expiration Time and the Current Market Price of the Common Stock on the Trading
Day next succeeding the Expiration Time, such reduction (if any) to become
effective immediately prior to the opening of business on the day following the
Expiration Time. In the event that the Corporation is obligated to purchase
shares pursuant to any such Tender Offer, but the Corporation is permanently
prevented by applicable law from effecting any such purchases or all such
purchases are rescinded, the Conversion Price shall again be adjusted to be the
Conversion Price which would then be in effect if such Tender Offer had not been
made. If the application of this Section 10(c)(6) to any Tender Offer would
result in an increase in the Conversion Price, no adjustment shall be made for
such Tender Offer under this Section 10(c)(6).

                  (7)      (1) In case at any time on or after the Issuance Date
the Corporation shall issue shares of its Common Stock or Common Stock
Equivalents (collectively, the "Newly Issued Shares"), other than an issuance
pro rata to all holders of its outstanding Common Stock,

                                       29

<PAGE>

at a price below the Current Fair Market Value of the Common Stock at the
time of such issuance, then following such issuance of Newly Issued Shares
the Conversion Price shall be adjusted as provided in this Section 10(c)(7).
The Conversion Price following any such adjustment shall be determined by
multiplying the Conversion Price immediately prior to such adjustment by a
fraction, of which the numerator shall be the sum of (a) the number of shares
of Common Stock outstanding immediately prior to the issuance of the Newly
Issued Shares (calculated on a fully-diluted basis assuming the conversion of
all options, warrants, purchase rights or convertible securities which are
exercisable at the time of the issuance of the Newly Issued Shares) PLUS (b)
the number of shares of Common Stock which the aggregate consideration, if
any, received by the Corporation for the number of Newly Issued Shares would
purchase at a price equal to the Current Fair Market Value of the Common
Stock at the time of such issuance, and the denominator shall be the sum of
(X) the number of shares of Common Stock outstanding immediately prior to the
issuance of the Newly Issued Shares (calculated on a fully-diluted basis
assuming the exercise or conversion of all options, warrants, purchase rights
or convertible securities which are exercisable or convertible at the time of
the issuance of the Newly Issued Shares) PLUS (Y) the number of Newly Issued
Shares. The adjustment provided for in this Section 10(c)(7) may be expressed
as the following mathematical formula:

                              ( O +(C / FMV))    x CP
                              ---------------
                     NCP =    ( O + N )
where,

         C   =    aggregate consideration received by the Corporation for the
                  Newly Issued Shares

         N   =    number of Newly Issued Shares

         O   =    number of shares of Common Stock outstanding (on a fully
                  diluted basis, as described above) immediately prior to the
                  issuance of the Newly Issued Shares

         FMV =    Current Fair Market Value of the Common Stock at the time of
                  issuance of the Newly Issued Shares

         CP  =    Conversion Price immediately prior to the issuance of the
                  Newly Issued Shares

         NCP =    Conversion Price immediately after the issuance of the Newly
                  Issued Shares

                  (2)      Notwithstanding the foregoing, no adjustment shall be
made under this Section 10(c)(7) by reason of:

                  (A)      the issuance by the Corporation of shares of Common
         Stock pro rata to all holders of the Common Stock so long as (i) any
         adjustment to the Conversion Price that is required by Section 10(c)(1)
         is made and (ii) the Corporation shall have given notice of such
         issuance thereof to the Holders pursuant to Section 10(e);

                  (B)      the issuance by the Corporation of Newly Issued
         Shares in an offering for cash for the account of the Corporation that
         is underwritten on a firm commitment basis and (i) is registered under
         the 1933 Act, or (ii) is sold in an offering to "qualified


                                       30
<PAGE>

         institutional buyers" as defined in, and in a transaction under, Rule
         144A under the 1933 Act.;

                  (C)      the issuance by the Corporation for cash of Newly
         Issued Shares in connection with a strategic alliance, collaboration,
         joint venture, partnership or similar arrangement of the Corporation
         with another Person which strategic alliance, collaboration, joint
         venture, partnership or similar arrangement relates to the
         Corporation's business as conducted immediately prior thereto and which
         Person is engaged in a business similar or related to the business of
         the Corporation so long as (x) the price per Newly Issued Share is not
         less than 85 percent of the Current Fair Market Value of the Common
         Stock on the date of issuance of such Newly Issued Shares and (y) the
         consideration other than cash which the Corporation receives in
         connection with such strategic alliance, collaboration, joint venture,
         partnership or similar arrangement has a value, as determined by the
         Board of Directors in its reasonable judgment and set forth in a Board
         Resolution, at least equal to the amount by which (i) the product of
         the number of Newly Issued Shares so issued TIMES the Current Fair
         Market Value of the Common Stock on the date such Newly Issued Shares
         are issued exceeds (ii) the aggregate cash consideration received by
         the Corporation for such Newly Issued Shares at the time of issuance
         thereof;

                  (D)      the issuance by the Corporation of shares of Common
         Stock upon conversion of the Series A Preferred Stock in accordance
         with the terms hereof;

                  (E)      the issuance by the Corporation of shares of Common
         Stock as dividends on the Series A Preferred Stock in accordance with
         the terms of Section 5;

                  (F)      the issuance by the Corporation of Common Stock upon
         the exercise of the Warrants in accordance with the terms thereof;

                  (G)      the issuance by the Corporation of shares of Common
         Stock to any employee, officer or director of, or consultant to, the
         corporation pursuant to any stock option plans or agreements approved
         by the Corporation's board of directors; and

                  (H)      the issuance by the Corporation of shares of Common
         Stock or other securities to any bank, equipment lessor or other
         similar financial institution in connection with commercial credit
         arrangements, equipment financing or similar transactions approved by
         the Corporation's board of directors.

                  (8)      The Corporation may make such reductions in the
Conversion Price, in addition to those required by Sections 10(c)(1), (2), (3),
(4), (5), (6), or (7) as the Board of Directors considers to be advisable to
avoid or diminish any income tax to holders of Common Stock or rights to
purchase Common Stock resulting from any dividend or distribution of stock (or
rights to acquire stock) or from any event treated as such for income tax
purposes.

                  (9)      No adjustment in the Conversion Price shall be
required unless such adjustment would require an increase or decrease of at
least 1% in such price; PROVIDED, HOWEVER, that any adjustments which by reason
of this Section 10(c)(9) are not required to be made shall be carried forward
and taken into account in any subsequent adjustment. All

                                       31

<PAGE>

calculations under this Section 10 shall be made by the Corporation and shall
be made to the nearest cent or to the nearest one hundredth of a share, as
the case may be.

                  No adjustment need be made for a change in the par value of
the Common Stock or from par value to no par value or from no par value to par
value.

                  (10)     Whenever the Conversion Price is adjusted as herein
provided, the Corporation shall promptly, but in no event later than five
business days thereafter, give notice to the Holders setting forth the
Conversion Price after such adjustment and setting forth a brief statement of
the facts requiring such adjustment, but which statement shall not include any
information which would be material non-public information for purposes of the
1934 Act. Failure to deliver such notice shall not affect the legality or
validity of any such adjustment.

                  (11)     In any case in which this Section 10(c) provides that
an adjustment shall become effective immediately after a Record Date for an
event, the Corporation may defer until the occurrence of such event (i) issuing
to the Holders in connection with any conversion of shares of Series A Preferred
Stock 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 Common Stock issuable upon
such conversion before giving effect to such adjustment and (ii) paying to such
Holders any amount in cash in lieu of any fraction pursuant to Section 10(b)(6).

                  (12)     For purposes of this Section 10(c), the number of
shares of Common Stock at any time outstanding shall not include shares held in
the treasury of the Corporation but shall include shares issuable in respect of
scrip certificates issued in lieu of fractions of shares of Common Stock. The
Corporation will not pay any dividend or make any distribution on shares of
Common Stock held in the treasury of the Corporation other than (i) dividends or
distributions payable only in shares of Common Stock and (ii) the Preferred
Stock Purchase Rights.

                  (13)     Before taking any action which would cause an
adjustment reducing the Conversion Price below the then par value, if any, of
the shares of Common Stock issuable upon conversion of the Series A Preferred
Stock, the Corporation shall take all corporate action which may, in the opinion
of its counsel, be necessary in order that the Corporation may validly and
legally issue shares of such Common Stock at such adjusted Conversion Price.

                  (d)      EFFECT OF RECLASSIFICATION, CONSOLIDATION, MERGER OR
SALE. (1) If any of the following events occur, namely (x) any reclassification
or change of the outstanding shares of Common Stock (other than a change in par
value, or from par value to no par value, or from no par value to par value, or
as a result of a subdivision or combination), (y) any consolidation, merger or
combination of the Corporation with another corporation or other entity as a
result of which holders of Common Stock shall be entitled to receive stock,
securities or other property or assets (including cash) with respect to or in
exchange for such Common Stock, or (z) any sale or conveyance of the properties
and assets of the Corporation as, or substantially as, an entirety to any other
corporation or other entity as a result of which holders of Common Stock shall
be entitled to receive stock, securities or other property or assets (including
cash) with respect to or in exchange for such Common Stock, then the Corporation
or the successor or purchasing corporation or other entity, as the case may be,
shall prior to such transaction amend its

                                       32

<PAGE>

certificate of incorporation or comparable instrument to provide that the
shares of Series A Preferred Stock shall following such transaction be
convertible into the kind and amount of shares of stock and other securities
or property or assets (including cash) receivable upon such reclassification,
change, consolidation, merger, combination, sale or conveyance by the holder
of a number of shares of Common Stock issuable upon conversion of shares of
Series A Preferred Stock immediately prior to such reclassification, change,
consolidation, merger, combination, sale or conveyance assuming such holder
of Common Stock did not exercise such holder's rights of election, if any, as
to the kind or amount of securities, cash or other property receivable upon
such consolidation, merger, statutory exchange, sale or conveyance (PROVIDED
that, if the kind or amount of securities, cash or other property receivable
upon such consolidation, merger, statutory exchange, sale or conveyance is
not the same for each share of Common Stock in respect of which such rights
of election shall not have been exercised ("non-electing share"), then for
the purposes of this Section 10(d) the kind and amount of securities, cash or
other property receivable upon such consolidation, merger, statutory
exchange, sale or conveyance for each non-electing share shall be deemed to
be the kind and amount so receivable per share by a plurality of the
non-electing shares). Such written agreement shall provide for adjustments
which shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Section 10. If, in the case of any such
reclassification, change, consolidation, merger, combination, sale or
conveyance, the stock or other securities and assets receivable thereupon by
a holder of shares of Common Stock includes shares of stock or other
securities and assets of a corporation other than the successor or purchasing
corporation or other entity, as the case may be, in such reclassification,
change, consolidation, merger, combination, sale or conveyance, then such
other corporation or other entity shall also so amend its certificate of
incorporation or comparable instrument and the certificate(s) of
incorporation or comparable instruments so amended shall also contain such
additional provisions to protect the interests of the Holders as the Board of
Directors shall reasonably consider necessary by reason of the foregoing,
including, to the extent practicable, the provisions providing for the
redemption rights set forth in Section 11.

                  (2)      The above provisions of this Section shall similarly
apply to successive reclassifications, changes, consolidations, mergers,
combinations, sales and conveyances.

                  (3)      If this Section 10(d) applies to any event or
occurrence, Section 10(c) shall not apply.

                  (e)      NOTICE TO HOLDER PRIOR TO CERTAIN ACTIONS. In case on
or after the Issuance Date:

                  (1)      the Corporation shall declare a dividend (or any
other distribution) on its Common Stock (other than in cash out of retained
earnings); or

                  (2)      the Corporation shall authorize the granting to the
holders of its Common Stock of rights or warrants to subscribe for or purchase
any share of any class or any other rights or warrants; or

                  (3)      the Board of Directors shall authorize any
reclassification of the Common Stock (other than a subdivision or combination of
its outstanding Common Stock, or a change in par value, or from par value to no
par value, or from no par value to par value), or any

                                       33

<PAGE>

consolidation or merger or other business combination transaction to which
the Corporation is a party and for which approval of any stockholders of the
Corporation is required, or the sale or transfer of all or substantially all
of the assets of the Corporation; or

                  (4)      there shall be pending the voluntary or involuntary
dissolution, liquidation or winding-up of the Corporation;

the Corporation shall give the Holders as promptly as possible but in any event
at least ten Trading Days prior to the applicable date hereinafter specified, a
notice stating (x) the date on which a record is to be taken for the purpose of
such dividend, distribution or rights or warrants, or, if a record is not to be
taken, the date as of which the holders of Common Stock of record to be entitled
to such dividend, distribution or rights are to be determined, or (y) the date
on which such reclassification, consolidation, merger, other business
combination transaction, sale, transfer, dissolution, liquidation or winding-up
is expected to become effective or occur, and the date as of which it is
expected that holders of Common Stock of record who shall be entitled to
exchange their Common Stock for securities or other property deliverable upon
such reclassification, consolidation, merger, other business combination
transaction, sale, transfer, dissolution, liquidation or winding-up shall be
determined. Such notice shall not include any information which would be
material non-public information for purposes of the 1934 Act. Failure to give
such notice, or any defect therein, shall not affect the legality or validity of
such dividend, distribution, reclassification, consolidation, merger, sale,
transfer, dissolution, liquidation or winding-up. In the case of any such action
of which the Corporation gives such notice to the Holders or is required to give
such notice to the Holders, the Holders shall be entitled to give a Conversion
Notice which is contingent on the completion of such action.

                  SECTION 11. REDEMPTION UPON HOLDER OPTIONAL REDEMPTION EVENT
OR REGISTRATION REDEMPTION EVENT.

                  (a)      REDEMPTION RIGHT UPON HOLDER OPTIONAL REDEMPTION
EVENT. If a Holder Optional Redemption Event shall occur at any time when any
shares of Series A Preferred Stock are outstanding, then, in addition to any
other rights of the Holders, each Holder shall have the right, at such Holder's
option, to require the Corporation to redeem all of such Holder's shares of
Series A Preferred Stock, or any portion thereof, on the date that is five
Business Days after the date such Holder gives a Holder Notice with respect to
such Holder Optional Redemption Event. Each share of Series A Preferred Stock
required to be so redeemed shall be redeemed at a price equal to the Holder
Optional Redemption Price.

                  (b)      NOTICES; METHOD OF EXERCISING OPTIONAL REDEMPTION
RIGHTS, ETC. (1) On or before the fifth Business Day after the occurrence of an
Holder Optional Redemption Event, the Corporation shall give to each Holder a
Corporation Notice of the occurrence of such Holder Optional Redemption Event
and of the redemption right set forth herein arising as a result thereof. The
Corporation Notice shall set forth:

                  (i)      the date by which the optional redemption right must
         be exercised, and

                  (ii)     a description of the procedure (set forth below)
         which each such Holder must follow to exercise such Holder's optional
         redemption right.

                                       34

<PAGE>

No failure of the Corporation to give a Corporation Notice or defect therein
shall limit the right of any Holder to exercise the Holder Optional Redemption
right or affect the validity of the proceedings for the redemption of such
Holder's shares of Series A Preferred Stock.

                  (2)      To exercise its optional redemption right, a Holder
shall deliver to the Corporation on or before the thirtieth day after a
Corporation Notice is given to such Holder (or if no Corporation Notice has been
given to such Holder, within forty days after such Holder first learns of the
Holder Optional Redemption Event) a Holder Notice to the Corporation setting
forth the name of such Holder, and number of such Holder's shares of Series A
Preferred Stock to be redeemed. A Holder Notice may be revoked by the Holder
giving such Holder Notice by giving notice of such revocation to the Corporation
at any time prior to the time the Corporation pays the applicable Holder
Optional Redemption Price to such Holder.

                  (3)      If a Holder shall have given a Holder Notice, then on
the applicable Holder Optional Redemption Date (or such later date as such
Holder surrenders such Holder's certificates for the shares of Series A
Preferred Stock redeemed) the Corporation shall make payment in immediately
available funds of the applicable Holder Optional Redemption Price to such
account as specified by such Holder in writing to the Corporation at least one
Business Day prior to the applicable Holder Optional Redemption Date. If all of
the shares of Series A Preferred Stock evidenced by a particular certificate are
to be redeemed under this Section 11(b), the Holder of such shares of Series A
Preferred Stock shall not be entitled to payment of the Holder Optional
Redemption Price of such shares of Series A Preferred Stock until such Holder
shall have surrendered the certificate(s) for such shares of Series A Preferred
Stock to the Corporation or, in the case of the loss, theft or destruction of
any such certificate, given indemnity in accordance with Section 14(b).

                  (c)      REDEMPTION RIGHT UPON REGISTRATION REDEMPTION EVENT.
If a Registration Redemption Event shall occur, then each Holder shall have the
right by complying with the requirements of this Section 11(c), at such Holder's
option, to require the Corporation to redeem all of such Holder's shares of
Series A Preferred Stock, or from time to time any portion thereof, by making
payment of the Registration Redemption Price to such Holder in immediately
available funds to such account as specified by such Holder by notice to the
Corporation, on the date that is five Business Days after the date a Holder
Registration Redemption Notice is given by such Holder (or such later date as
such Holder surrenders to the Corporation the certificate(s) for the shares of
Series A Preferred Stock redeemed). A Holder shall exercise its right to require
redemption pursuant to this Section 11(c) by giving a Holder Registration
Redemption Notice at any time after a Registration Redemption Event occurs and
prior to the SEC Effective Date. If a Holder shall have given a Holder
Registration Redemption Notice, the Corporation shall redeem such Holder's
shares of Series A Preferred Stock or the portion of such Holder's shares of
Series A Preferred Stock as stated in such Holder Registration Redemption Notice
at a price per share equal to the Registration Redemption Price. A Holder of
shares of Series A Preferred Stock which are redeemed pursuant to this Section
11(c) shall not be entitled to payment of the Registration Redemption Price of
such shares of Series A Preferred Stock until such Holder shall have surrendered
the certificate(s) for such shares of Series A Preferred Stock to the
Corporation or, in the case of the loss, theft or destruction of any such
certificate, given indemnity in accordance with Section 14(b). A Holder
Registration Redemption Notice may be revoked by the Holder giving such Holder
Registration Redemption Notice by giving notice of such

                                       35

<PAGE>

revocation to the Corporation at any time prior to the time the Corporation
pays the Registration Redemption Price to such Holder.

                  (d)      OTHER. (1) A Holder Notice or Holder Registration
Redemption Notice given by a Holder shall be deemed for all purposes to be in
proper form unless the Corporation notifies such Holder in writing within three
Business Days after such Holder Notice or Holder Registration Redemption Notice
has been given (which notice shall specify all defects in such Holder Notice or
Holder Registration Redemption Notice), and any Holder Notice or Holder
Registration Redemption Notice containing any such defect shall nonetheless be
effective on the date given if such Holder promptly undertakes to correct all
such defects. Notwithstanding the absence of any such undertaking from such
Holder, no such claim of error shall limit or delay performance of the
Corporation's obligation to redeem all shares of Series A Preferred Stock not in
dispute.

                  (2)      If the Corporation fails to redeem on the applicable
redemption date of any share of Series A Preferred Stock as to which the
redemption right of a Holder has been properly exercised, then the Holder
Optional Redemption Price or the Registration Repurchase Price, as the case may
be, for such share shall bear interest to the extent not prohibited by
applicable law from the applicable redemption date until paid at the Arrearage
Interest rate.

                  (3)      If on or before the applicable date for redemption
pursuant to this Section 11 the Corporation shall have failed to pay in full the
Holder Optional Redemption Price or the Registration Redemption Price for any
shares of Series A Preferred Stock to be redeemed to the holders thereof or to
deposit the same with an Eligible Bank in accordance with Section 14(c), then
without in any way relieving the Corporation of its obligation to pay such
amount in accordance herewith (except to the extent expressly provided in this
Section 11(d)(3)), the Holder of any such share of Series A Preferred Stock
shall continue to have the right to convert such share of Series A Preferred
Stock into Common Stock in accordance with Section 10(a) at any time prior to
the date on which the Corporation pays the Holder Optional Redemption Price or
Registration Redemption Price, as the case may be, of such share of Series A
Preferred Stock to such Holder (together with any amount due to such holder
pursuant to Section 14(d)) or so deposits the same (together with any amount due
to such Holder pursuant to Section 14(d)) and gives notice to such Holder of
such deposit; PROVIDED, HOWEVER, that the shares of Common Stock received by
such Holder upon any such conversion in certain circumstances may be subject to
restrictions on resale by such Holder arising under applicable securities laws
to the extent not registered for resale by such Holder pursuant to the
Registration Statement. If a Holder converts all or any portion of such Holder's
shares of Series A Preferred Stock as permitted by this Section 11(d)(3), the
amount of the Holder Optional Redemption Price or the Registration Redemption
Price, as the case may be, due to such Holder with respect to the number of
shares of Series A Preferred Stock so converted shall be reduced by the Stated
Value for each share of Series A Preferred Stock so converted.

                  (4)      If a portion of the shares of Series A Preferred
Stock represented by a particular certificate are to be redeemed, upon surrender
of such certificate to the Corporation in accordance with the terms of this
Section 11, the Corporation shall execute and deliver to the Holders of such
certificate without service charge, a new certificate or certificates, in such
denomination or denominations as requested by such Holder.

                  (a)      VOTING RIGHTS. Except as otherwise required by law or
expressly provided herein, shares of Series A Preferred Stock shall not be
entitled to vote on any matter.

                  (b)      CERTIFICATE OF INCORPORATION; CERTAIN STOCK. The
affirmative vote or written consent of the Majority Holders, voting separately
as a class, will be required for (1) any amendment, alteration, or repeal,
whether by merger or consolidation or otherwise, of the Corporation's
Certificate of Incorporation if the amendment, alteration, or repeal materially
and adversely affects the powers, preferences, or special rights of the Series A
Preferred Stock, or (2) the creation or issuance of any Senior Dividend Stock,
Senior Liquidation Stock, Parity Dividend Stock or Parity Liquidation Stock;
PROVIDED, HOWEVER, that any increase in the authorized Preferred Stock of the
Corporation or the creation and issuance of any stock which is both Junior
Dividend Stock and Junior Liquidation Stock shall not be deemed to affect
materially and adversely such powers, preferences, or special rights and any
such increase or creation and issuance may be made without any such vote by the
Holders except as otherwise required by law; and PROVIDED FURTHER, HOWEVER, that
no such amendment, alteration or repeal shall (i) reduce the Mandatory
Redemption Price, Holder Optional Redemption Price, Redemption Price,
Registration Redemption Price or the amount payable to a holder of shares of
Series A Preferred Stock pursuant to Section 5(b) or 5(c), (ii) change the
definition of Majority Holders, (iii) change the method of calculating the
Conversion Price in a manner adverse to the Holders or reduce the number of
shares of Common Stock issuable upon any conversion of shares of Series A
Preferred Stock (other than any reduction in the number of shares of Common
Stock so issuable pursuant to an amendment of the Certificate of Incorporation
which effects a combination of the outstanding shares of Common Stock and
results in an adjustment in the Conversion Price pursuant to Section 10(c)(3)),
or (iv) amend, modify or repeal any provision of this Section 12(b), unless in
each such case referred to in the preceding clauses (i) through (iv) such
amendment, modification or repeal has been approved by the affirmative vote or
written consent of all holders, voting separately as a class.

                  (c)      REPURCHASES OF SERIES A PREFERRED STOCK. The
Corporation shall not repurchase or otherwise acquire any shares of Series A
Preferred Stock (other than pursuant to Section 7(a), Section 9(a) or Section
11) unless the Corporation offers to repurchase or otherwise acquire
simultaneously a pro rata portion of each Holder's shares of Series A Preferred
Stock based on the ratio of the number of shares of Series A Preferred Stock
held by such Holder to the total number of shares of Series A Preferred Stock
outstanding for cash at the same price per share.

                  (d)      OTHER. So long as any shares of Series A Preferred
Stock are outstanding the Corporation shall comply with the following unless
otherwise agreed in writing by the Majority Holders.

                  (1)      LIMITATIONS ON ASSET SALES, LIQUIDATIONS, ETC.;
CERTAIN MATTERS. The Corporation shall not and shall not permit any Subsidiary
to:

                                       37

<PAGE>

                  (a)      sell, convey or otherwise dispose of all or
substantially all of the assets of the Corporation as an entirety or
substantially as an entirety in a single transaction or in a series of related
transactions; or

                  (b)      liquidate, dissolve or otherwise wind up the affairs
of the Corporation or any Subsidiary. For purposes of the preceding clause (b),
a consolidation or merger of the Corporation or any Subsidiary in and of itself
shall not be considered a liquidation, dissolution or winding up of the
Corporation or such Subsidiary.

                  (2)      LIMITATIONS ON ISSUANCE OF SECURITIES. The
Corporation shall not (i) issue any security that is convertible into or
otherwise entitles the holder to acquire Common Stock at a price that varies
based on changes in the market price of the Common Stock, (ii) issue Common
Stock under any arrangement for re-pricing or adjusting the price after the
issuance, or (iii) issue any other preferred stock that is senior to, or at
parity with, the Preferred Stock.

In no event, however, shall the Corporation be prevented from issuing shares of
capital stock pursuant to either a secondary public offering, or a private
investment for publicly traded shares; provided that while the Preferred Stock
is outstanding the Holders shall have a right of first refusal to participate in
whole or in part in any such offering or private investment.

                  (3)      TRANSACTIONS WITH AFFILIATES. The Corporation will
not, and will not permit any Subsidiary, directly or indirectly, to pay any
funds to or for the account of, make any investment (whether by acquisition of
stock or indebtedness, by loan, advance, transfer of property, guarantee or
other agreement to pay, purchase or service, directly or indirectly, any
indebtedness, or otherwise) in, lease, sell, transfer or otherwise dispose of
any assets, tangible or intangible, to, or participate in, or effect any
transaction in connection with, any joint enterprise or other joint arrangement
with, any Affiliate of the Corporation, except, on terms to the Corporation or
such Subsidiary no less favorable than terms that could be obtained by the
Corporation or such Subsidiary from a Person that is not an Affiliate of the
Corporation, as determined in good faith by the Board of Directors.

                  SECTION 13. OUTSTANDING SHARES. For purposes of this
Certificate of Designations, all shares of Series A Preferred Stock shall be
deemed outstanding except (i) from the date a Conversion Notice is given by a
holder of Series A Preferred Stock, all shares of Series A Preferred Stock
converted into Common Stock (so long as the Corporation shall issue the shares
of Common Stock issuable upon such conversion as and when required by this
Certificate of Designations); (ii) from the date of registration of transfer,
all shares of Series A Preferred Stock held of record by the Corporation or any
subsidiary or Affiliate (as defined herein) of the Corporation (other than any

Date, Holder Optional Redemption Date, Redemption Date or date of redemption
pursuant to Section 11(c), all shares of Series A Preferred Stock which are

                                       38

<PAGE>

Stock shall have been paid by the Corporation as and when due hereunder or
deposited in accordance with Section 14(c).

                  SECTION 14. MISCELLANEOUS.

                  (a)      NOTICES. Any notices required or permitted to be
given under the terms of this Certificate of Designations shall be in writing
and shall be delivered by telephone line facsimile transmission or if no
telephone line facsimile transmission number shall have been provided for such
purpose, shall be delivered personally or by courier or by mail and shall be
deemed given upon receipt, if delivered by telephone line facsimile
transmission, personally or by courier or five days after being placed in the
mail (certified mail, return receipt requested, in the case of any such notice
to a Person at an address in the United States of America), if mailed (a) in the
case of the Corporation, addressed to the Corporation at 863A Mitten Road,
Burlingame, California 94010, Attention: Chief Financial Officer (telephone line
facsimile transmission number (650) 652-1990), or, (b) in the case of any
Holder, at such Holder's address or telephone line facsimile transmission number
or address shown on the stock books maintained by the Corporation with respect
to the Series A Preferred Stock or such other telephone line facsimile
transmission number or address as the Corporation shall have provided by notice
to the Holders in accordance with this Section 14(a) or any Holder shall have
provided to the Corporation in accordance with this Section 14(a).

                  (b)      REPLACEMENT OF CERTIFICATES. Upon receipt by the
Corporation of evidence reasonably satisfactory to the Corporation of the
ownership of and the loss, theft, destruction or mutilation of any certificate
for shares of Series A Preferred Stock and (1) in the case of loss, theft or
destruction, of indemnity from the Holder of the certificate for such shares of
Series A Preferred Stock reasonably satisfactory in form to the Corporation (and
without the requirement to post any bond or other security) or (2) in the case
of mutilation, upon surrender and cancellation of the certificate for such
shares of Series A Preferred Stock, the Corporation will execute and deliver to
such Holder a new certificate for such shares of Series A Preferred Stock
without charge to such Holder.

                  (c)      PAYMENT ON REDEMPTION; DEPOSIT OF REDEMPTION PRICE.
If any share of Series A Preferred Stock is to be redeemed and any notice
required in connection therewith shall have been timely given as provided
therein, the applicable redemption price of such share of Series A Preferred
Stock to be so redeemed and with respect to which any such notice has been given
shall become due and payable on the applicable redemption date. On and after
such redemption date, provided that the Corporation shall have paid such
redemption price to the respective Holders who are entitled thereto on or prior
to the applicable redemption date or shall have deposited with an Eligible Bank
on or prior to such redemption date, to be held in trust for the respective
Holders entitled thereto, an amount sufficient to pay the applicable redemption
price, then on such redemption date the dividends on such share of Series A
Preferred Stock shall cease to accrue, and such share of Series A Preferred
Stock shall be deemed not to be outstanding and the Holder thereof shall not be
entitled to any rights of a Holder except to receive payment of the applicable
redemption price and all other rights hereunder with respect to such share of
Series A Preferred Stock shall cease. So long as the Corporation shall have so
paid or deposited the full amount of the applicable redemption price on a timely
basis, no Holder shall be entitled to interest on the amount so held by such
Eligible Bank and, so long as the

                                       39

<PAGE>

Corporation shall be in compliance in all material respects with its
obligations to the Holders (including, without limitation, its obligations
under the Transaction Documents), the Corporation shall be entitled to any
interest paid by such Eligible Bank on the funds so deposited, subject to
applicable abandoned property and escheat laws. On presentation and surrender
of the certificate for such share of Series A Preferred Stock, such share
shall be redeemed at the applicable redemption price.

                  (d)      OVERDUE AMOUNTS. If the Corporation fails to pay when
due or to deposit with an Eligible Bank in accordance with Section 14(c) the
full amount of the Mandatory Redemption Price, the Holder Optional Redemption
Price, the Redemption Price or the Registration Redemption Price on or before
the respective Initial Mandatory Redemption Date and Final Mandatory Redemption
Date, Holder Optional Redemption Date, Redemption Date or the date of redemption
specified in Section 11(b) or the date of redemption specified in Section 11(c),
in each such case for the number of shares of Series A Preferred Stock to be
redeemed on such date or to pay any other amount to any Holder when due, then
the amount thereof shall bear interest at the Arrearage Interest rate (or such
lesser rate as shall be the maximum rate allowed by applicable law) from such
date until paid or so deposited in full or until such share of Series A
Preferred Stock is converted in accordance with this Certificate of Designations
(in which case such interest shall remain due and payable).

                  (e)      CERTAIN CHANGES IN LAW. To the extent that the 1933
Act or the 1934 Act or any statutes, rules or regulations promulgated thereunder
relating to the registration for public sale of securities and/or the
registration of issuers thereof are superseded, replaced or repealed, the
requirements of this Certificate of Designations relating to such statutes,
rules and regulations shall be applied as nearly as practicable with respect to
such successor statutes, rules or regulations, if any, to achieve the purposes
intended hereby.
