the Series D and Series D-1 Preferred Stock shall be entitled to receive in
preference to the holders of all other classes and series of stock an amount per

held by each (assuming full conversion of such Preferred Stock).

                  (c)      (i)      For purposes of this Section 2, a
liquidation, dissolution or winding up of this corporation shall be deemed to be
occasioned by, or to include, (A) the acquisition of this corporation by another
entity by means of any transaction or series of related transactions (including,
without limitation, any reorganization, merger or consolidation, but excluding
any merger effected exclusively for the purpose of changing the domicile of this
corporation) unless this corporation's stockholders of record as constituted
immediately prior to such acquisition or sale will immediately after such
acquisition or sale by virtue of securities issued as consideration for this
corporation's acquisition or sale or otherwise) hold at least 50% of the voting
power of the surviving or acquiring entity; or (B) a sale of all or
substantially all of the assets of this corporation.

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

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

bid or sale prices (whichever is applicable) over the thirty-day period ending
three (3) days prior to the closing; and

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

                                    (B)      The method of valuation of
securities subject to investment letter or other restrictions on free
marketability (other than restrictions arising solely by virtue of a
shareholder's status as an affiliate or former affiliate) shall be to make
an appropriate discount from the market value determined as above in (A)(1), (2)


                                      -4-

material terms and conditions of the impending transaction and the provisions
of this Section 2, and this corporation shall thereafter give such holders
prompt notice of any material changes, The transaction shall in no event take
place sooner than twenty (20) days after this corporation has given the first
notice provided for herein or sooner than ten (10) days after this corporation
has given notice of any material changes provided for herein; provided, however,
that such periods may be shortened upon the written consent of the holders of
Preferred Stock that are entitled to such notice fights or similar notice

   8

corporation or of any transfer agent for the Preferred Stock, and shall give
written notice to this corporation at such office, of the election to convert
the same, and shall state therein the name or names in which the certificate or
certificates for shares of Common Stock are to be issued. This corporation
shall, as soon as practicable thereafter, issue and deliver at such office to
such holder of Preferred Stock, or to the nominee or nominees of such holder, a
certificate or certificates for the number of shares of Common Stock to which
such holder shall be entitled as aforesaid, and, if less than all of the shares
of Preferred Stock represented by such certificate or certificates surrendered
to the corporation are to be converted, a certificate for the number of
unconverted shares of Preferred Stock. Such conversion shall be deemed to have
been made immediately prior to the close of business on the date of such
surrender of shares of Preferred Stock to be converted, and the person or
persons entitled to receive the shares of Common Stock issuable upon such
conversion shall be treated for all purposes as the record holder or holders of
such shares of Common Stock as of such date. If the conversions in connection
with an underwritten offering of securities registered pursuant to the Act, the
conversion may, at the option of any holder tendering Preferred Stock for
conversion, be conditioned upon the closing with the underwriters of the sale of
securities pursuant to such offering, in which event the person(s) entitled to
receive the Common Stock upon conversion of the Preferred Stock shall not be
deemed to have converted such Preferred Stock until immediately prior to the
closing of such sale of securities.

Conversion Price of the Series A, Series B, Series C and Series D Preferred
Stock shall be subject to adjustment from time to time as follows:

                  (i)      (A) If this corporation shall issue or declare, after
the date upon which any shares of Series A Preferred Stock are first issued (the
"Series A Purchase Date"), any Additional Stock (as defined below in subsection
3(d)(ii)) without consideration or for a consideration per share less than the
Conversion Price for the Series A Preferred Stock in effect immediately prior to
the issuance of such Additional Stock, the Series A Preferred Stock Conversion
Price in effect immediately prior to each such issuance shall forthwith (except
as otherwise provided in this clause (i)) be adjusted to a price determined by
multiplying such Conversion Price by a fraction, the numerator of which shall be
the number of shares of Common Stock outstanding immediately prior to the stock
issuance plus the number of shares of Common Stock that the aggregate
consideration received by this corporation for such issuance would purchase at
such Conversion Price; and the denominator of which shall be the number of
shares of Common Stock outstanding immediately prior to such issuance plus the
number of shares of such Additional Stock. For purposes of determining "the

"Series B Purchase Date"), any Additional Stock without consideration or for a
consideration per share less than the Conversion Price for the Series B
Preferred Stock in effect immediately prior to the issuance of such Additional
Stock, the Series B Preferred Stock Conversion Price in effect immediately prior
to each such issuance shall forthwith (except as otherwise provided in this
clause (i)) be adjusted to a price determined by multiplying such Conversion
Price by a fraction, the numerator of which shall be the number of shares of
Common Stock outstanding immediately prior to the stock issuance plus the number
of shares of Common Stock that the aggregate consideration received by this
corporation for such issuance would purchase at such Conversion Price; and the
denominator of which shall be the number of shares of common Stock outstanding
immediately prior to such issuance plus the number of shares of such Additional
Stock. For purposes of determining "the number of shares of Common Stock
outstanding immediately prior to such issuance" in the foregoing sentence, only
shares of Common Stock actually outstanding shall be counted, notwithstanding
any other provision of this Section 3.

                           (C) If this corporation shall issue or declare, after
the date upon which any shares of Series C Preferred Stock are first issued (the
"Series C Purchase Date"), any Additional Stock without consideration or for a
consideration per share less than the Conversion Price for the Series C
Preferred Stock in effect immediately prior to the issuance of such Additional
Stock, the Series C Preferred Stock Conversion Price in effect immediately prior
to each such issuance shall forthwith (except as otherwise provided in this
clause (i)) be adjusted to a price determined by multiplying such Conversion
Price by a fraction, the numerator of which shall be the number of shares of
Common Stock outstanding immediately prior to the stock issuance plus the number
of shares of Common Stock that the aggregate consideration received by this
corporation for such issuance would purchase at such Conversion Price; and the
denominator of which shall be the number of shares of Common Stock outstanding
immediately prior to such issuance plus the number of shares of such Additional
Stock. For purples of determining "the number of shares of Common Stock
outstanding immediately prior to such issuance" in the foregoing sentence,
only shares of Common Stock actually outstanding shall be counted,

the date upon which any shares of Series D Preferred Stock are first issued (the
"Series D Purchase Date"), any Additional Stock without consideration or for a
consideration per share less than the Conversion Price for the Series D
Preferred Stock in effect immediately prior to the issuance of such Additional
Stock, the Series D Preferred Stock Conversion Price in effect immediately prior
to each such issuance shall forthwith (except as otherwise provided in this
clause (i)) be adjusted to a price determined by multiplying such Conversion
Price by a fraction, the numerator of which shall be the number of shares of
Common Stock outstanding immediately prior to the stock issuance plus the number
of shares of Common Stock that the aggregate consideration received by this
corporation for


                                      -9-
   10


such issuance would purchase at such Conversion Price; and the denominator of
which shall be the number of shares of Common Stock outstanding immediately
prior to such issuance plus the number of shares of such Additional Stock. For
purposes of determining "the number of shares of Common Stock outstanding
immediately prior to such issuance" in the foregoing sentence, only shares of
Common Stock actually outstanding shall be counted, notwithstanding any
provision of this Section 3.

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

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

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

                           (H) In the case of the issuance. (whether before, on
or after the Series A, Series B, Series C or Series D Purchase Date,
respectively) of options to purchase or rights to subscribe for Common Stock,
securities by their terms convertible into or exchangeable for Common Stock, or
options to purchase or rights to subscribe for such convertible or exchangeable
securities, the following provisions shall apply for all purposes of this
subsection 3(d)(i) and subsection 3(d)(ii):

                                    (1) The aggregate maximum number of shares
of Common Stock deliverable upon exercise (assuming the satisfaction of any
conditions to exercisability, including without limitation, the passage of time,
but without taking into account potential antidilution adjustments,) of such
options to purchase or rights to subscribe for Common Stock shall be deemed to
have been issued at the time such securities were issued or such options or
rights were issued and for a consideration equal to the consideration
(determined in the manner provided in subsections 3(d)(i)(F) and (d)(i)(G)), if
any, received by this corporation upon the issuance of such options or rights




                                      -10-
   11


plus the minimum exercise price provided in such options or rights (without
taking into account potential antidilution adjustments) for the Common Stock
covered thereby.

                                    (2) The aggregate maximum number of shares
of Common Stock deliverable upon conversion of or in exchange (assuming the
satisfaction of any conditions to convertibility or exchangeability, including,
without limitation, the passage of time, but without taking into account
potential antidilution adjustments) for any such convertible or exchangeable
securities or upon the exercise of options to purchase or rights to subscribe
for such convertible or exchangeable securities and subsequent conversion or
exchange thereof shall be deemed to have been issued at the time such securities
were issued or such options or rights were issued and for a consideration equal
to the consideration, if any, received by this corporation (without taking into
account potential antidilution adjustments) upon the conversion or exchange of
such securities or the exercise of any related options or rights (the
consideration in each case to be determined in the manner provided in
subsections 3(d)(i)(F) and (d)(i)(G)).

                                    (3) In the event of any change in the number
of shares of Common Stock deliverable or in the consideration payable to this
corporation upon exercise of such options or rights or upon conversion of or in
exchange for such convertible or exchangeable securities, including, but not
limited to, a change resulting from the antidilution provisions thereof, the
Conversion Price of the Series A, Series B, Series C, or Series D Preferred
Stock, to the extent in any way affected by or computed using such options,
rights or securities, shall be recomputed to reflect such change, but no
further adjustment shall be made for the actual issuance of Common Stock or any
payment of such consideration upon the exercise of any such options or rights or
the conversion or exchange of such securities.

                                    (4) Upon the expiration of any such options
or rights, the termination of any such rights to convert or exchange or the
expiration of any options or rights related to such convertible or exchangeable
securities, the Conversion Price of the Series A, Series B, Series C and Series
D Preferred Stock, to the extent any way affected by or computed using such
options, rights or securities or options or rights related to such securities,
shall be recomputed to reflect the issuance of only the number of shares of
Common Stock (and convertible or exchangeable securities which remain in effect)
actually issued upon the exercise of such options or rights, upon the conversion
or exchange of such securities or upon the exercise of the options or rights
related to such securities.

                                    (5) The number of shares of Common Stock
deemed issued and the consideration deemed paid therefor pursuant to subsections
3(d)(i)(H)(1) and (2) shall be appropriately adjusted to reflect any change,
termination or expiration of the type described in either subsection
3(d)(i)(H)(3) or (4).

                           (ii)     "Additional Stock" shall mean with respect
to the Series A, Series B, Series C or Series D Preferred Stock any shares of
Common Stock issued (or deemed to have been issued pursuant to subsection
3(d)(i)(H)) by this corporation after the Series A, Series B, Series C or Series
D Purchase Date, respectively, other than:

                                    (A) Common Stock issued pursuant to a
transaction described in subsection 3(d)(iii) hereof; or

                                    (B) Up to 1,750,000 shares of Common Stock
(adjusted for stock splits, stock dividends or recapitalizations) issuable or
issued to employees, consultants and directors of this corporation pursuant to a
stock option plan or stock purchase plan approved by the Board of Directors of
this corporation at any time.

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

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

                  (e)      OTHER DISTRIBUTIONS. In the event this corporation
shall declare a distribution payable in securities of other persons, evidences
of indebtedness issued by this corporation or other persons, assets (excluding
cash dividends) or options or rights not referred to in subsection 3(d)(iii),
then, in each such case for the purpose of this subsection 3(e), the holders of
Preferred Stock shall be entitled to a proportionate share of any such
distribution as though they were the holders of the number of shares of




                                      -12-
   13


Common Stock of this corporation into which their shares of Preferred Stock,
are convertible as of the record date fixed for the determination of the holders
of Common Stock of this corporation entitled to receive such distribution.

                  (f)      RECAPITALIZATIONS. If at any time or from time to
time there shall be a recapitalization of the Common Stock (other than a
subdivision, combination or merger or sale of assets transaction provided for in
Section 2 or elsewhere in this Section 3), provision shall be made so that the
holders of the Preferred Stock shall thereafter be entitled to receive upon
conversion of the Preferred Stock the number of shares of stock or other
securities or property of the Company or otherwise to which a holder of Common
Stock deliverable upon conversion would have been entitled on such
recapitalization. In any such case, appropriate adjustment shall be made in the
application of the provisions of this Section 3 with respect to the rights of
the holders of the Preferred Stock after the recapitalization to the end that
the provisions of this Section 3 (including adjustment of the Conversion Prices
then in effect and the number of shares purchasable upon conversion of the
Preferred Stock) shall be applicable after that event as nearly equivalent as
may be practicable,

                  (g)      NO IMPAIRMENT. This corporation will not, by
amendment of its Certificate of Incorporation or through any reorganization,
recapitalization, transfer of assets, consolidation, merger, dissolution, issue
or sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed
hereunder by this corporation, but will at all times in good faith assist in the
carrying out of all the provisions of this Section 3 and in the taking of all
such action as may be necessary or appropriate in order to protect the
Conversion Rights of the holders of the Preferred Stock against impairment.

                  (h)      NO FRACTIONAL SHARES AND CERTIFICATE AS TO
ADJUSTMENTS.

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

                           (ii)     Upon the occurrence of each adjustment or
readjustment of the Conversion Prices of Preferred Stock pursuant to this
Section 3, this corporation, at its expense, shall promptly compute such
adjustment or readjustment in accordance with the terms hereof and prepare and
furnish to each holder of Preferred Stock a certificate setting forth such
adjustment or readjustment and showing in detail the facts upon which such
adjustment or readjustment is based. This corporation shall, upon the written
request at any time of any holder of Preferred Stock, furnish or cause to be
furnished to such holder a like certificate setting forth (A) such adjustment
and




                                      -13-
   14


readjustment, (B) the Conversion Price for each series of Preferred Stock at the
time in effect, and (C) the number of shares of Common Stock and the amount, if
any, of other property that at the time would be received upon the conversion of
a share of such Preferred Stock.

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

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

                  (k)      NOTICES. Any notice required by the provisions of
this Section 3 to be given to the holders of shares of Preferred Stock shall be
deemed given if deposited in the United States mail, postage prepaid, and
addressed to each holder of record at his address appearing on the books of this
corporation.

                  (l)      SPECIAL MANDATORY CONVERSION; DILUTIVE ISSUES:

                           (i)      At anytime following the Series A Purchase
Date, if: (a) a holder of shares of Series A Preferred Stock is entitled to
exercise the right of first offer (the "Right of First Offer") set forth in
Section 2.1 of the Third Amended and Restated Rights Agreement dated October 29,
1999, by and among this corporation and certain investors, as amended from time
to time (the "Rights Agreement"), with respect to an equity financing of this
corporation (the "Equity Financing"), at a price per share that is less than
the Conversion Price then in effect for the Series A Preferred Stock; and (b)
the holders of a majority of the Series A Preferred Stock entitled to
participate in the Equity Financing acquire their pro rata shares (as defined in
Section 2.1 of the Rights


                                      -14-
   15

Agreement) offered in such Equity Financing; and (c) such holder (a
"Non-Participating Holder") does not by exercise of such holder's Right of First
Offer acquire his, her or its pro rata share offered in such Equity Financing
and the holders of a majority of shares of Series A Preferred Stock do exercise
their respective Right of First Offer to acquire his, her or its pro rata share
offered in such Equity Financing (a "Mandatory Offering"), then all of such
Non-Participating Holder's shares of Series A Preferred Stock shall
automatically and without further action on the part of such holder be converted
effective upon, subject to, and concurrently with, the consummation of the
Mandatory Offering (the "Mandatory Offering Date") into an equivalent number of
shares of Series A-l Preferred Stock. Upon conversion pursuant to this
subsection 3(1)(i), the shares of Series A Preferred Stock so converted shall be
canceled and not subject to reissuance.

                           (ii)     The holder of any shares of Series A
Preferred Stock converted pursuant to this subsection 3(1) shall deliver to this
corporation alluring regular business hours at the office of any transfer agent
of this corporation for the Series A Preferred Stock, or at such other place as
may be designated by this corporation, the certificate or certificates for the
shares so converted, duly endorsed or assigned in blank or to this corporation.
As promptly as practicable thereafter, this corporation shall issue and deliver
to such holder, at the place designated by such holder, a certificate or
certificates for the number of full shares of Series A-1 Preferred Stock to be
issued and such holder shall be deemed to have become a shareholder of record of
Series A-I Preferred Stock, on the Mandatory Offering Date, unless the transfer
books of this corporation have closed on that date, in which event he, she or it
shall be deemed to have become a shareholder of record of Series A-1 Preferred
Stock, on the next succeeding date on which the transfer books are open.

                           (iii)    In the event that any Series A-1 Preferred
Stock shares are issued, concurrently with such issuance, this corporation shall
use its best efforts to take all such action as may be required, including
amending its Certificate of Incorporation, (a) to cancel all authorized shares
of Series A-1 Preferred Stock that remain unissued after such issuance, (b) to
create and reserve for issuance upon any subsequent conversion pursuant to this
subsection 3(1) of any Series A Preferred Stock a new series of Preferred Stock
equal in number to the number of shares of Series A-1 Preferred Stock so
canceled and designated Series A-2 Preferred Stock, with the designation,
powers, preferences and rights and the qualifications, limitations and
restrictions identical to those then applicable to the Series A-1 Preferred
Stock, except that the Conversion price for such shares of Series A-2 Preferred
Stock shall be the Series A Conversion Price in effect immediately prior to the
issuance of such shares of Series A-2 Preferred Stock and (e) to amend the
provisions of this sub section 3(1) to provide that any subsequent conversion
pursuant to this subsection 3(1) will be into shares of Series A-2 Preferred
Stock rather than Series A-1 Preferred Stock, as the case may be. This
corporation shall take the same actions with respect, to the Series A-2
Preferred Stock, and each subsequently authorized series of Preferred Stock upon
the issuance of shares of the last such series to be authorized. The right to
receive any dividend declared but unpaid at the time of conversion on any shares
of Preferred Stock converted pursuant to




                                      -15-
   16


the provisions of this subsection 3(1) shall accrue to the benefit of the new
shares of Preferred Stock issued upon conversion thereof.

                           (iv)     At any time following the Series B Purchase
Date, if: (a) a holder of shares of Series B Preferred Stock is entitled to
exercise the right of first offer (the "Right of First Offer") set forth in
Section 2.1 of the Rights Agreement, with respect to an Equity Financing at a
price per share that is less than the Conversion Price then in effect for the
Series B Preferred Stock; and (b) the holders of a majority of the Series B
Preferred Stock entitled to participate in the Equity Financing acquire their
pro rata shares (as defined in Section 2.1 of the Rights Agreement) offered in
such Equity Financing; and (c) such holder (a "Non-Participating Holder") does
not by exercise of such holder's Right of First Offer acquire his, her or its
pro rata share offered in such Equity Financing and the holders of a majority of
shares of Series B Preferred Stock do exercise their respective Right of First
Offer to acquire his, her or its pro rata share offered in such Equity Financing
(a "Mandatory Offering"), then all of such Non-Participating Holder's shares of
Series B Preferred Stock shall automatically and without further action on the
part of such holder be converted effective upon, subject to, and concurrently
with, the consummation of the Mandatory Offering on the Mandatory Offering Date
into an equivalent number of shares of Series B-1 Preferred Stock. Upon
conversion pursuant to this subsection 3(1)(iv), the shares of Series B
Preferred Stock so converted shall be canceled and not subject to reissuance.

                           (v)      The holder of any shares of Series B
Preferred Stock converted pursuant to this subsection 3(1) shall deliver to this
corporation during regular business hours at the office of any transfer agent of
this corporation for the Series B Preferred Stock, or at such other place as may
be designated by this corporation, the certificate or certificates for the
shares so converted, duly endorsed or assigned in blank or to this corporation.
As promptly as practicable thereafter, this corporation shall issue and deliver
to such holder, at the place designated by such holder, a certificate or
certificates for the number of full shares of Series B-1 Preferred Stock to be
issued and such holder shall be deemed to have become a shareholder of record of
Series B-1 Preferred Stock, on the Mandatory Offering Date, unless the transfer
books of this corporation have closed on that date, in which event he, she or it
shall be deemed to, have become a shareholder of record of Series B-1 Preferred
Stock, on the next succeeding date on which the transfer books are open.

                           (vi)     In the event that any Series B-1 Preferred
Stock shares are issued, concurrently with such issuance, this corporation shall
use its best efforts to take all such action as may be required, including
amending its Certificate of Incorporation, (a) to cancel all authorized shares
of Series B-1 Preferred Stock that remain unissued after such issuance, (b) to
create and reserve for issuance upon any subsequent conversion pursuant to this
subsection 3(1) of any Series B Preferred Stock a new series of Preferred Stock
equal in number to the number of shares of Series B-1 Preferred Stock so
canceled and designated Series B-2 Preferred Stock, with the designation,
powers, preferences and fights and the qualifications, limitations and


                                      -16-
   17

restrictions identical to those then applicable to the Series B-1 Preferred
Stock, except that the Conversion Price for such shares of Series B-2 Preferred
Stock shall be the Series B Conversion Price in effect immediately prior to the
issuance of such shares of Series B-2 Preferred Stock and (e) to amend the
provisions of this subsection 3(1) to provide that any subsequent conversion
pursuant to this subsection 3(1) will be into shares of Series B-2 Preferred
Stock rather than Series B-1 Preferred Stock. This corporation shall take the
same actions with respect to the Series B-2 Preferred Stock, and each
subsequently authorized series of Preferred Stock upon the issuance of shares of
the last such series to be authorized. The right to receive any dividend
declared but unpaid at the time of conversion on any shares of Preferred Stock
converted pursuant to the provisions of this subsection 3(1) shall accrue to the
benefit of the new shares of Preferred Stock issued upon conversion thereof.

                           (vii)    At any time following the Series C Purchase
Date, if: (a) a holder of shares of Series C Preferred Stock is entitled to
exercise the right of first offer (the "Right of First Offer") set forth in
Section 2.1 of the Rights Agreement, with respect to an Equity Financing at a
price per share that is less than the Conversion Price then in effect for the
Series C Preferred Stock; and (b) the holders of a majority of the Series C
Preferred Stock entitled to participate in the Equity Financing acquire their
pro rata shares (as defined in Section 2.1 of the Right s Amendment) offered in
such Equity Financing; and (c) such holder (a "Non-Participating Holder") does
not by exercise of such holder's Right of First Offer acquire his, her or its
pro rata share offered in such Equity Financing and the holders of a majority of
shares of Series C Preferred Stock do exercise their respective Right of First
offer to acquire his, her or its pro rata share offered in such Equity Financing
(a "Mandatory Offering"), then all of such Non-Participating Holder's shares of
Series C Preferred Stock shall automatically and without further action on the
part of such holder be converted effective upon, subject to, and concurrently
with, the consummation of the Mandatory Offering on the Mandatory Offering Date
into an equivalent number of shares of Series C-1 Preferred Stock. Upon
conversion pursuant to this subsection 3(1)(vii), the shares of Series C
Preferred Stock so converted shall be canceled and not subject to reissuance.

                           (viii)   The holder of any shares of Series C
Preferred Stock converted pursuant to this subsection 3(1) shall deliver to this
corporation during regular business hours at the office of any transfer agent of
this corporation for the Series C Preferred Stock, or at such other place as may
be designated by this corporation, the certificate or certificates for the

As promptly as practicable thereafter, this corporation shall issue and deliver
to such holder, at the place designated by such holder, a certificate or
certificates for the number of full shares of Series C-1 Preferred Stock to be
issued and such holder shall be deemed to have become a shareholder of record of
Series C-1 Preferred Stock, on the Mandatory Offering Date, unless the transfer
books of this corporation have closed on that date, in which event he, she or
it shall be deemed to have become a shareholder of record of Series C-1
Preferred Stock, on the next succeeding date on which the transfer books are
open.


                                      -17-
   18

                           (ix)     In the event that any Series C-1 Preferred
Stock shares are issued, concurrently with such issuance, this corporation shall
use its best efforts to take all such action as may be required, including
amending its Certificate of Incorporation, (a) to cancel all authorized shares
of Series C-1 Preferred Stock that remain unissued after such issuance, (b) to
create and reserve for issuance upon any subsequent conversion pursuant to this
subsection 3(1) of any Series C Preferred Stock a new series of Preferred Stock

powers, preferences and rights and the qualifications, limitations and
restrictions identical to those then applicable to the Series C-1 Preferred
Stock, except that the Conversion Price for such shares of Series C-2 Preferred
Stock shall be the Series C Conversion Price in effect immediately prior to the
issuance of such shares of Series C-2 Preferred Stock and (c) to amend the
provisions of this subsection 3(1) to provide that any subsequent conversion
pursuant to this subsection 3(1) will be into shares of Series C-2 Preferred
Stock rather than Series C-l Preferred Stock. This corporation shall take the
same actions with respect to the Series C-2 Preferred Stock, and each
subsequently authorized series of Preferred Stock upon the issuance of shares of
the last such series to be authorized. The right to receive any dividend
declared but unpaid at the time of conversion on any shares of Preferred Stock
converted pursuant to the provisions of this subsection 3(1) shall accrue to the
benefit of the new shares of Preferred Stock issued upon conversion thereof.

                           (x)      At any time following the Series D Purchase
Date, if: (a) a holder of shares of Series D Preferred Stock is entitled to

Offer to acquire his, her or its pro rata share offered in such Equity Financing
(a "Mandatory Offering"), then all of such Non-Participating Holder's shares of
Series D Preferred Stock shall automatically and without further action on the
part of such holder be convened effective upon, subject to, and concurrently

it, to an equivalent number of shares of Series D-1 Preferred Stock. Upon
conversion pursuant to this subsection 3(1)(x), the shares of Series D Preferred

shareholder of record of Series D-1 Preferred Stock, on the next succeeding date
on which the transfer books are open.

                           (xii)    In the event that any Series D-1 Preferred
Stock shares are issued, concurrently with such issuance, this corporation shall
use its best efforts to take all such action as may be required, including
amending its Certificate of Incorporation, (a) to cancel all authorized, shares
of Series D-1 Preferred Stock that remain unissued after such issuance, (b) to
create and reserve for issuance upon any subsequent conversion pursuant to this
subsection 3(1) of any Series D Preferred Stock a new series of Preferred Stock
equal in number to the number of shares of Series D-1 Preferred Stock so
canceled and designated Series D-2 Preferred Stock, with the designation,
powers, preferences and rights and the qualifications, limitations and
restrictions identical to those then applicable to the Series D-1 Preferred
Stock, except that the Conversion Price for such shares of Series D-2 Preferred
Stock shall be the Series D Conversion Price in effect immediately prior to the
issuance of such shares of Series D-2 Preferred Stock and (c) to amend the
provisions of this subsection 3(1) to provide that any subsequent conversion
pursuant to this subsection 3(1) will be into shares of Series D-2 Preferred
Stock rather than Series D-1 Preferred Stock. This corporation shall take the
same actions with respect to the Series D-2 Preferred Stock, and each
subsequently authorized series of Preferred Stock upon the issuance of shares of
the last such series to be authorized. The right to receive any dividend
declared but unpaid at the time of conversion on any shares of Preferred Stock
converted pursuant to the provisions of this subsection 3(1) shall accrue to the
benefit of the new shares of Preferred Stock issued upon conversion thereof.

         4.       VOTING RIGHTS.

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


                                      -19-
   20

could be converted) shall be rounded to the nearest whole number (with one-half
being rounded upward).

                  (b)      VOTING FOR ELECTION OF DIRECTORS. The board of
directors of the Company (the "Board") shall consist of seven (7) members.
Notwithstanding any other provision of this Certificate of Incorporation, so
long as no fewer than 1,000,000 shares of Series A, Series B and Series C
Preferred Stock (subject to appropriate adjustment for stock splits, stock
dividends, combinations and other recapitalizations) remain outstanding, the
holders of the Series A, Series B and Series C Preferred Stock then outstanding
shall be entitled, voting separately as one class, to elect two (2) directors of
this corporation at each election of directors. Notwithstanding any other
provision of this Certificate of Incorporation, and notwithstanding the addition
of subsequent investors or the election of a new CEO, the holders of the Series
D Preferred Stock shall be entitled, voting separately as a class, to elect
three (3) directors of this corporation at each election of directors (the
"Series D Directors"). For so long as Baker and Fidelity own, in the aggregate,
a majority of the outstanding Series D Preferred Stock, one (1) of the Series D
Directors shall be designated by Fidelity and two (2) of the Series D Directors
shall be designated by Baker. Notwithstanding any other provision of this
Certificate of Incorporation, the holders of the Common Stock then outstanding
shall be entitled to elect one (1) director of this corporation at each
election of directors. Notwithstanding any other provision of this Certificate
of incorporation, the remaining director of this corporation shall be the Chief
Executive Officer of the Company, subject to approval of both of (i) the holders
of Preferred Stock voting as a separate class, and (ii) the holders of Common
Stock voting as a separate class. In the case of any vacancy in the office of a
director elected by the holders of a particular class or series of stock, the
vacancy may be filled only by the vote of the holders of such class or series of
stock. Any director who shall have been elected by the holders of particular
class or series of stock may be removed without cause by, and only by, the
applicable vote of the holders of shares of such class or series of stock.

         5.       REDEMPTION.

         (a)      REDEMPTION ON DEMAND. In the event that holders of at least a
majority of the then outstanding Series D Preferred Stock so request, in
writing, at any time on or after October 29, 2006, this corporation shall, on
the date sixty (60) days after such notice is given (the "Redemption Date"), to
the extent it may lawfully do so, redeem up to 100% of the number shares of
Series D Preferred Stock then held by such holders, by paying the Redemption
Price thereof.

         (b)      REDEMPTION PRICE. The price per share to be paid to redeem the
Series D Preferred Stock shall be an amount equal to the greater of (i) the sum
of $7.72 per share (adjusted to reflect subsequent stock dividends, stock splits
or recapitalizations) plus all accrued and unpaid dividends calculated at a
dividend rate of 10% (whether or not declared) or (ii) the fair market value per
share as determined by an independent appraiser


                                      -20-
   21


mutually acceptable to this corporation and the holders of a majority of the
shares of Series D Preferred Stock then outstanding; provided, that if this
corporation and such holders are unable to agree on a single appraiser, this
corporation, on the one hand, and the holders of a majority of the shares of
Series D Preferred Stock then outstanding, on the other hand, shall each select
a single independent appraiser reasonably qualified to conduct business
valuations of such nature, and such appraisers shall agree on the Redemption
Price or shall select a third appraiser who shall determine the Redemption
Price.

         (c)      PARTIAL REDEMPTION. In the event of any redemption of only a
part of the then outstanding Series D Preferred Stock, the corporation shall
effect such redemption pro rata among the holders of Series D Preferred Stock
requesting redemption according to the aggregate number of outstanding shares of
Series D Preferred Stock requested to be redeemed by each such holder.

         (d)      REDEMPTION PROCEDURE. At least 30 days prior to the Redemption
Date, written notice (the "Redemption Notice") shall be mailed, postage prepaid,
to each holder of record (at the close of business on the business day next
preceding the day on which Notice is given) of the Series D Preferred Stock, at
the address last shown on the records of the corporation for such holder or
given by the holder to the corporation for the purpose of notice or if no such
address appears or is given, at the place where the principal executive office
of the corporation is located, notifying such holder of the redemption to be
effected, specifying the number of shares to be redeemed, the Redemption Price,
the place at which payment may be obtained and calling upon such holder to
surrender to the corporation, in the manner and at the place designated, its
certificate or certificates representing the shares to be redeemed. Except as
provided in subsection (e) below, on or after the Redemption Date, each holder
of Preferred Stock to be redeemed shall surrender to the corporation the
certificate or certificates representing such shares, in the manner and at the
place designated in the Redemption Notice, and thereupon, subject to the
provisions of subsection (c) above, the aggregate Redemption Price of such
shares shall be payable to the order of the person whose name appears on
such certificate or certificates as the owner thereof and each surrendered
certificate shall be cancelled. In the event less than all the shares
represented by any such certificate are redeemed, a new certificate shall be
issued representing the unredeemed shares.

         (e)      EFFECT OF REDEMPTION. From and after the Redemption Date,
unless there shall have been a default in payment of the Redemption Price, all
rights of the holders of such redeemed shares as holders of Series D Preferred
Stock (except the right to receive their respective Redemption Price without
interest upon surrender of their certificate or certificates) shall cease with
respect to such shares, and such shares shall not thereafter be transferred on
the books of the corporation or be deemed to be outstanding for any purpose
whatsoever. If the funds of the corporation legally available for redemption on
any Redemption Date are insufficient to redeem the total number of shares
requested to be redeemed on such date, those funds which are legally available
will be used to redeem the maximum possible number of such shares pro rata as
described in subsection (c)


                                      -21-
   22


above. The shares not redeemed shall remain outstanding and be entitled to all
the rights and preferences provided herein. At any time thereafter when
additional funds of the corporation are legally available for the redemption of
shares not redeemed, such funds will immediately be set aside for the redemption
of the balance of the shares which the corporation has become obligated to
redeem on any Redemption Date but which it has not redeemed; provided that the
holders of such Series D Preferred Stock shall receive at least 10 days notice
of such redemption.

         6.       PROTECTIVE PROVISIONS. So long as any shares of any series of
Preferred Stock are outstanding, this corporation shall not without first
obtaining the approval (by vote or written consent, as provided by law) of the
holders of at least a majority of the then outstanding shares of each class of
Preferred Stock voting as a separate class:


                  (a)      alter or change the rights, preferences or privileges
of the shares of such series of Preferred Stock so as to affect adversely such
shares in a manner different than any other series;

                  (b)      increase or decrease (other than by redemption or
conversion) the total number of authorized shares of such series of Preferred
Stock;

                  (c)      reclassify any outstanding equity security into an
equity security having a preference over, or being on a parity with, such
series of Preferred Stock with respect to voting, dividends, redemption or upon
liquidation;

                  (d)      amend the corporation's Certificate of Incorporation
or bylaws in any manner that materially adversely affects such series of
Preferred Stock;

                  (e)      make any material change in the principal business of
the corporation;

                  (f)      except as provided in Section 5 hereof, repurchase
any equity security, except that the corporation may without such consent
repurchase Common Stock from current or former directors, employees and/or
consultants with a repurchase price equal to the initial cost of such Common
Stock; or
                  (g)      declare or pay any dividend with respect to the
Common Stock.

         7.       STATUS OF CONVERTED. In the event any shares of Preferred
Stock shall be converted pursuant to Section 3 hereof, the shares so converted
shall be canceled and shall not be subject to reissuance by this corporation.

         8.       REPURCHASE OF SHARES. Each holder of Preferred Stock shall be
deemed to have consented to distributions made by the corporation in connection
with the




                                      -22-
   23

repurchase of Common Stock issued to or held by employees, directors or
consultants upon termination of their employment or services.

         C.       COMMON STOCK

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

                  2.       LIQUIDATION RIGHTS. Upon liquidation, dissolution or
winding up of this corporation the assets of the corporation shall be
distributed as provided in Section 2 of Division B of this Article FOURTH.

                  3.       VOTING RIGHTS.

                           (b)      VOTING FOR ELECTION OF DIRECTORS. The

Section 4(b) of Division B of this Article.
