          (a)  In the event of any liquidation, dissolution or winding up of the
Corporation (a "Liquidation"), the funds and assets of the Corporation legally
available for distribution to its stockholders (the "Corporate Assets") shall be
distributed as follows:

               (i)  First, before any distribution of assets shall be made to
the holders of Common Stock, Series A Preferred Stock, Series B Preferred Stock
or Series C Preferred Stock and before any distribution of assets in respect of
the Series D-1 Additional Preference (defined below) shall be made to the
holders of the Series D-1 Preferred Stock, (A) the holders of each share of
Series D Preferred Stock then outstanding shall be entitled to be paid out of
the Corporate Assets an amount per share equal to the Series D Original Purchase
Price (subject to Adjustment), plus all dividends, including the Series D
Cumulative Dividend, accrued but unpaid on such shares up to the date of
distribution of the Corporate Assets (the "Series D Liquidation Preference"),
(B) the holders of each share of Series D-2 Preferred Stock then outstanding
shall be entitled to be paid out of the Corporate Assets an amount per

                                       -8-



share equal to the Series D-2 Original Purchase Price (subject to Adjustment),
plus all dividends, including the Series D-2 Cumulative Dividend, accrued but
unpaid on such shares up to the date of distribution of the Corporate Assets
(the "Series D-2 Liquidation Preference"), (C) the holders of each share of
Series D-3 Preferred Stock then outstanding shall be entitled to be paid out of
the Corporate Assets an amount per share equal to the Series D-3 Original
Purchase Price (subject to Adjustment), plus all dividends, including the Series
D-3 Cumulative Dividend, accrued but unpaid on such shares up to the date of
distribution of the Corporate Assets (the "Series D-3 Liquidation Preference")
and (D) the holders of each share of Series D-4 Preferred Stock then outstanding
shall be entitled to be paid out of the Corporate Assets an amount per share
equal to the Series D-4 Original Purchase Price (subject to Adjustment), plus
dividends, including the Series D-4 Cumulative Dividend, accrued but unpaid on
such shares up to the date of distribution of the Corporate Assets (the "Series
D-4 Liquidation Preference"). If, upon the occurrence of a Liquidation, the
Corporate Assets shall be insufficient to pay to the holders of shares of Series
D Preferred Stock the Series D Liquidation Preference, to pay to the holders of
shares of Series D-2 Preferred Stock the Series D-2 Liquidation Preference, to
pay to the holders of shares of Series D-3 Preferred Stock the Series D-3
Liquidation Preference or to pay to the holders of shares of Series D-4
Preferred Stock the Series D-4 Liquidation Preference, the holders of shares of
Series D Preferred Stock, Series D-2 Preferred Stock, Series D-3 Preferred Stock
and Series D-4 Preferred Stock shall share ratably in the distribution of the
entire Corporate Assets in proportion to the respective amounts (excluding
amounts payable in respect of the Series D-1 Additional Preference) which would
otherwise be payable in respect of the shares held by them upon such
distribution if all amounts (excluding amounts payable in respect of the Series
D-1 Additional Preference) payable on or with respect to such shares were paid
in full.

               (ii)  Second, before any distribution of assets shall be made to
the holders of Common Stock, Series A Preferred Stock, or Series B Preferred
Stock and before any distribution of assets in respect of the Series D-1
Additional Preference shall be made to the holders of the Series D-1 Preferred
Stock, the holders of each share of Series C Preferred Stock then outstanding
shall be entitled to be paid out of the Corporate Assets an amount per share
equal to the Series C Original Purchase Price (subject to Adjustment), plus all
dividends, including the Series C Cumulative Dividends, accrued but unpaid on
such shares up to the date of distribution of the Corporation Assets (the
"Series C Liquidation Preference"). If upon the occurrence of a Liquidation, the
Corporate Assets shall be insufficient to pay to the holders of shares of Series
C Preferred Stock the Series C Liquidation Preference, the holders of shares of
Series C Preferred Stock shall share ratably in the distribution of the entire
remaining Corporate Assets in proportion to the respective amounts which would
otherwise be payable in respect of the shares held by them upon such
distribution if all amounts payable on or with respect to such shares were paid
in full.

               (iii) Third, before any distribution of assets shall be made to
the holders of Common Stock or the Series A Preferred Stock and before any
distribution of assets in respect of the Series D-1 Additional Preference shall
be made to the holders of the Series D-1 Preferred Stock, the holders of each
share of Series B Preferred Stock then outstanding shall be entitled to be paid
out of the Corporate Assets an amount per share equal to the Series B Original
Purchase Price (subject to Adjustment), plus all dividends, including the Series
B Cumulative Dividends, accrued but unpaid on such shares up to the date of
distribution of the Corporate Assets (the "Series B Liquidation Preference"). If
upon the occurrence of a Liquidation, the Corporate Assets shall be insufficient
to pay to the holders of shares of Series B Preferred Stock the Series B
Liquidation Preference, the holders of shares of Series B Preferred Stock shall
share ratably in the distribution of the entire remaining Corporate Assets in
proportion to the respective amounts which would otherwise be payable in respect
of the shares

                                       -9-



held by them upon such distribution if all amounts payable on or with respect to
such shares were paid in full.

               (iv)  Fourth, before any distribution of assets shall be made to
the holders of Common Stock and before any distribution of assets in respect of
the Series D-1 Additional Preference shall be made to the holders of the Series
D-1 Preferred Stock, the holders of each share of Series A Preferred Stock then
outstanding shall be entitled to be paid out of the Corporate Assets an amount
per share equal to the Series A Original Purchase Price (subject to Adjustment),
plus all dividends declared but unpaid on such shares up to the date of
distribution of the Corporate Assets (the "Series A Liquidation Preference"). If
upon the occurrence of a Liquidation, the Corporate Assets shall be insufficient
to pay the holders of shares of Series A Preferred Stock the Series A
Liquidation Preference, the holders of shares of Series A Preferred Stock shall
share ratably in the distribution of the entire remaining Corporate Assets in
proportion to the respective amounts which would otherwise be payable in respect
of the shares held by them upon such distribution if all amounts payable on or
with respect to such shares were paid in full.

               (v)   Fifth, before any distribution of assets shall be made to
the holders of Common Stock, the holders of each share of Series D-1 Preferred
Stock then outstanding shall be entitled to be paid out of the Corporate Assets
an amount per share equal to 20% of the Series D Original Purchase Price
(subject to Adjustment) (the "Series D-1 Additional Preference," and together
with the Series A Liquidation Preference, Series B Liquidation Preference, the
Series C Liquidation Preference, the Series D Liquidation Preference, the Series
D-2 Liquidation Preference, the Series D-3 Liquidation Preference and the Series
D-4 Liquidation Preference, the "Liquidation Preference"). If upon the
occurrence of a Liquidation, the Corporate Assets shall be insufficient to pay
the holders of the Series D-1 Preferred Stock the Series D-1 Additional
Preference, the holders of shares of Series D-1 Preferred Stock shall share
ratably in the distribution of the entire remaining Corporate Assets in
proportion to the respective amounts which would otherwise be payable in respect
of the Series D-1 Additional Preference upon such distribution if the Series D-1
Additional Preference with respect to the Series D-1 Preferred Stock were paid
in full.

               (vi)  Sixth, after distribution of the Liquidation Preference,
the remaining Corporate Assets shall be distributed among the holders of Common
Stock and the holders of the Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock, Series D Preferred Stock, Series D-1 Preferred Stock,
Series D-2 Preferred Stock, Series D-3 Preferred Stock and Series D-4 Preferred
Stock on a pro rata basis, with the amount distributable computed on the basis
of the number of shares of Common Stock which would be held by such holders of
Preferred Stock if immediately prior to the Liquidation all of the shares of the
Preferred Stock had been converted into shares of Common Stock.

          (b)  Notwithstanding anything to the contrary contained in the
foregoing, (i) if as a result of receiving any distributions as described in
Section 3(a) above, the holders of the Series D-4 Preferred Stock would receive
an amount per share greater than the product obtained by multiplying the Series
D-4 Liquidation Preference by one (1) (the "Series D-4 Trigger Price"), then
such holders shall receive the greater of the Series D-4 Trigger Price or the
amount such holder would receive by sharing the Corporate Assets with the
holders of Common Stock on an as-converted basis upon Liquidation.

          (c)  Notwithstanding anything to the contrary contained in the
foregoing, (i) if as a result of receiving any distributions as described in
Section 3(a) above, the holders of the Series D-3 Preferred Stock would receive
an amount per share greater than the product obtained by multiplying the

                                       -10-



Series D-3 Liquidation Preference by one (1) (the "Series D-3 Trigger Price"),
then such holders shall receive the greater of the Series D-3 Trigger Price or
the amount such holder would receive by sharing the Corporate Assets with the
holders of Common Stock on an as-converted basis upon Liquidation.

          (d)  Notwithstanding anything to the contrary contained in the
foregoing, (i) if as a result of receiving any distributions as described in
Section 3(a) above, the holders of the Series D-2 Preferred Stock would receive
an amount per share greater than the product obtained by multiplying the Series
D-2 Liquidation Preference by one (1) (the "Series D-2 Trigger Price"), then
such holders shall receive the greater of the Series D-2 Trigger Price or the
amount such holder would receive by sharing the Corporate Assets with the
holders of Common Stock on an as-converted basis upon Liquidation.

          (e)  Notwithstanding anything to the contrary contained in the
foregoing, (i) if as a result of receiving any distributions as described in
Section 3(a) above, the holders of the Series D Preferred Stock would receive an
amount per share greater than the product obtained by multiplying the Series D
Liquidation Preference by three (3) (the "Series D Trigger Price"), then such
holders shall receive the greater of the Series D Trigger Price or the amount
such holder would receive by sharing the Corporate Assets with the holders of
Common Stock on an as-converted basis upon Liquidation.

          (f)  Notwithstanding anything to the contrary contained in the
foregoing, if as a result of receiving any distributions as described in Section
3(a) above, the holders of the Series C Preferred Stock would receive an amount
greater than $4.16 per share (the "Series C Trigger Price"), then such holders
shall receive the greater of the Series C Trigger Price or the amount such
holder would receive by sharing the Corporate Assets with the holders of Common
Stock on an as-converted basis upon Liquidation.

          (g)  Notwithstanding anything to the contrary contained in the
foregoing, if as a result of receiving any distributions as described in Section
3(a) above, the holders of the Series B Preferred Stock would receive an amount
per share greater than the product obtained by multiplying the Series B Original
Purchase Price by four (4) (the "Series B Trigger Price"), then such holders
shall receive the greater of the Series B Trigger Price or the amount such
holder would receive by sharing the Corporate Assets with the holders of Common
Stock on an as-if converted basis upon Liquidation.

          (h)  (i) The merger or consolidation of the Corporation with or into
any other entity, or other similar transaction or series of related
transactions, in which the holders of the Corporation's outstanding shares
immediately before such merger, or consolidation do not, immediately subsequent
to such merger or consolidation, retain stock or other equity interests
representing a majority of the voting power of the surviving entity of such
consolidation or merger; or (ii) a transaction or series of related transactions
whereby all or substantially all the assets of the Corporation are sold, leased,
transferred or otherwise disposed of (any of the foregoing events referred to in
this Section 3(h) a "Sale Transaction"), shall be deemed to be a Liquidation for
purposes of this Section 3, unless the holders of at least sixty-six and
two-thirds percent (66 2/3%) of the then outstanding shares of Preferred Stock
(on an as converted basis) elect otherwise by giving written notice thereof to
the Corporation at least three (3) days prior to the effective date of such
event. The amount deemed distributed for purposes of determining the Liquidation
Preference for the holders of shares of Preferred Stock upon any such
transaction deemed to be a Liquidation shall be the cash or the value of the
property, rights or securities distributed to such holders by the acquiring
person, firm or other entity. The value of such property, rights or other
securities shall be determined in good faith by the Board of Directors of the
Corporation (including at

                                      -11-



least two (2) Preferred Stock Directors (as defined in Section 4(j) of this
Charter,)) subject to Sections 3(i) and 3(j) below.

          (i)  The method of valuation of securities distributed to stockholders
on a Liquidation pursuant to this Section 3 that are not subject to investment
letter or other similar restrictions on free marketability shall be as follows:

               (i)   if the securities are then traded on a national securities
exchange or the NASDAQ National Market System (or a similar national quotation
system) or the NASDAQ Small Cap Market, then the value shall be deemed to be the
average of the closing prices of the securities over the thirty (30) day period
ending three (3) days prior to the distribution;

               (ii)  if actively traded over-the-counter, then the value shall
be deemed to be the average of the closing bid prices over the thirty (30) day
period ending three (3) days prior to the closing of such Liquidation; or

               (iii) if there is no active public market, then the value shall
be the fair market value thereof, as determined in good faith by the Board of
Directors of the Corporation (including at least two (2) Preferred Stock
Directors).

          (j)  The method of valuation of securities distributed to stockholders
in a Liquidation pursuant to this Section 3 that are subject to investment
letter or other restrictions on free marketability shall be to make an
appropriate discount from the market value determined pursuant to Section
3(i)(i), (ii), or (iii) above to reflect the approximate fair market value
thereof, as determined in good faith by the Board of Directors of the
Corporation (including at least two (2) Preferred Stock Directors).

          (k)  Written notice of a Liquidation, stating a payment date, the

convertible (as adjusted from time to time pursuant to Section 5 hereof), at
each meeting of stockholders of the Corporation (and written actions of
stockholders in lieu of meetings) with respect to any and all matters presented
to the stockholders of the Corporation for their action or consideration at the
record date for the determination of the stockholders entitled to vote on such
matters or, if no such record date is established, the date such vote is taken
or any written consent of stockholders is solicited. Except as provided by law
and by the provisions of Section 4(b), (c) (d), (e), (f), (g), (h) (i), (j) or
(k) below, the holders of shares of Preferred Stock shall vote together with the

          (a)  Optional Conversion. Each share of Preferred Stock shall be
convertible, at the option of the holder thereof, at any time and from time to
time.

          (b)  Automatic Conversion.

               (i)  Each share of Preferred Stock shall automatically be
converted at the then effective Conversion Price (subject to Adjustment) in the
manner provided herein into fully paid and nonassessable shares of Common Stock:

                    (A)  Immediately prior to the closing of a firm commitment
underwritten public offering pursuant to a registration statement filed under
the Securities Act of 1933, as amended (the "Securities Act"), covering the
offer and sale of Common Stock for the account of the Corporation in which (i)
the public offering price is at least $3.300573532 (subject to Adjustment) and
(ii) the aggregate net proceeds (after deduction of underwriter's discounts and
commissions) to the Corporation are at least $20,000,000 (a "Qualified Public
Offering"); it being understood, that such conversion shall occur solely upon
closing of such offering and not at any time prior thereto including the time of
effectiveness of such registration statement;

                    (B)  With the consent of the holders of sixty-six and
two-thirds percent (66-2/3%) of the issued and outstanding shares of the
Preferred Stock (on an as converted basis); or

                    (C)  Immediately prior to the closing of a Sale Transaction
in which the cash or readily marketable securities of a publicly traded company
paid or issued to the holders of the Series B Preferred Stock, Series C
Preferred Stock, Series D Preferred Stock, the Series D-2 Preferred Stock, the
Series D-3 Preferred Stock and the Series D-4 Preferred Stock equals or exceeds
the Series D Trigger Price (as defined in Section 3(d)) (a "Qualifying Sale
Transaction").

               (ii) In the case of an automatic conversion pursuant to this
Section 5(b), the outstanding shares of Preferred Stock shall be converted
automatically without any further action by the holders of such shares and
whether or not the certificates representing such shares are surrendered to the
Corporation or its transfer agent; provided, however, that the Corporation shall
not be obligated to issue to any holder certificates evidencing the shares of
Common Stock issuable upon such conversion, unless certificates evidencing such
shares of Preferred Stock are delivered either to the Corporation or any
transfer agent of the Corporation, as provided below, or the holder notifies the
Corporation or its transfer

                                       -17-



agent that such certificates have been lost, stolen or destroyed and executes an
agreement satisfactory to the Corporation to indemnify the Corporation from any
loss incurred by it in connection with such certificates. Upon the occurrence of
such automatic conversion of the Preferred Stock, the holders of Preferred Stock
shall surrender the certificates representing such shares at the office of the
Corporation or any transfer agent for the Preferred Stock or Common Stock.
Thereupon, there shall be issued and delivered to such holder promptly at such
office and in its name as shown on such surrendered certificate or certificates,
a certificate or certificates for the number of shares of Common Stock into
which the shares of Preferred Stock surrendered were convertible on the date on
which such automatic conversion occurred. All dividends will cease to accrue
upon conversion pursuant to this Section 5(b).

               (iii) All certificates evidencing shares of Preferred Stock which
are required to be surrendered for conversion in accordance with the provisions
hereof shall, from and after the date such certificates are so required to be
surrendered, be deemed to have been retired and canceled and the shares of
Preferred Stock represented thereby converted into Common Stock for all
purposes, notwithstanding the failure of the holder or holders thereof to
surrender such certificates on or prior to such date. The Corporation may
thereafter take such appropriate action as may be necessary to reduce the
authorized Preferred Stock accordingly.

          (c)  Conversion Mechanism and Conversion Price. Upon conversion in
accordance with Sections 5(a) or 5(b), each share of Preferred Stock shall be
converted, without payment of additional consideration by the holder thereof,
into that number of fully paid and non-assessable shares of Common Stock equal
to the quotient obtained by dividing (i) the applicable Original Purchase Price
(without Adjustment) by (ii) the then applicable Conversion Price (as defined
below). The conversion price per share at which shares of Common Stock shall be
issuable upon conversion of shares of Preferred Stock (the "Conversion Price")
shall initially be the Original Purchase Price for such series of Preferred
Stock; provided, however, that it is acknowledged (i) that as a result of a 2:1
stock split on the Common Stock effective on October 13, 2000, the date of the
filing of the Corporation's Third Amended and Restated Certificate of
Incorporation, an Adjustment was made to the Conversion Price of the Series A
Preferred Stock and Series B Preferred Stock and (ii) that as a result of a 5:4
stock split on the Common Stock effective on October 23, 2001, an Adjustment was
made to the Conversion Price of the Series A Preferred Stock, the Series B
Preferred Stock, the Series C Preferred Stock and the Series D Preferred Stock.
Such Conversion Price, and the rate at which shares of Preferred Stock may be
converted into shares of Common Stock, shall be subject to adjustment as
provided below.

          (d)  Fractional Shares. No fractional shares of Common Stock shall be
issued upon conversion of the shares of Preferred Stock. In lieu of any
fractional shares to which the holder would otherwise be entitled, the
Corporation shall pay the holder cash equal to the product of such fraction
multiplied by the Common Stock's fair market value as determined in good faith
by the Board of Directors of the Corporation as of the date of conversion.

          (e)  Mechanics of Conversion.

               (i)   Subject to Section 5(b)(ii) and Section 5(b)(iii), in order
for a holder of shares of Preferred Stock to convert shares of Preferred Stock
into shares of Common Stock, such holder shall surrender the certificate or
certificates evidencing the ownership of such shares of Preferred Stock at the
office of the Corporation or any transfer agent for the Preferred Stock or
Common Stock of the transfer agent for the shares of Preferred Stock (or at the
principal office of the Corporation if the Corporation serves as its own
transfer agent), together with written notice that such holder elects to

                                       -18-



convert all or any number of the shares of the Preferred Stock represented by
such certificate or certificates. Such notice shall state such holder's name or
the names of the nominees in which such holder wishes the certificate or
certificates for shares of Common Stock to be issued. Notwithstanding Section
5(b)(ii), and if required by the Corporation, certificates surrendered for
conversion shall be endorsed or accompanied by a written instrument or
instruments of transfer, in form reasonably satisfactory to the Corporation,
duly executed by the registered holder or his or its attorney-in-fact duly
authorized in writing. The date of receipt of such certificates and notice by
the transfer agent (or by the Corporation if the Corporation serves as its own
transfer agent) shall be the conversion date (the "Conversion Date"). The
Corporation shall, as soon as practicable after the Conversion Date, issue and
deliver at such office to such holder of shares of Preferred Stock, or to his or
its nominees, a certificate or certificates for the number of shares of Common
Stock to which such holder shall be entitled, together with cash in lieu of any
fractional shares to which such holder would otherwise be entitled, together
with cash in lieu of any fraction of a share. Such conversion shall be deemed to
have been made immediately prior to the close of business on the date of such
surrender of the shares of Preferred Stock to be converted, and the person or
persons entitled to receive the shares of Common Stock issuable upon such
conversion shall be treated for all purposes as the record holder or holders of
such shares of Common Stock as of such date. Other than as set forth in this
Section 5, if the conversion is made in connection with an underwritten offering
of securities registered pursuant to the Securities Act, the conversion may, at
the option of any holder tendering shares of Preferred Stock for conversion, be
conditioned upon the closing of the sale of securities pursuant to such
offering, in which event the person entitled to receive the Common Stock
issuable upon such conversion of the shares of Preferred Stock shall not be
deemed to have converted such shares of Preferred Stock until immediately prior
to the closing of such sale of securities.

               (ii)  In the event of the conversion of the Series D Preferred
Stock or Series D-4 Preferred Stock pursuant to Sections 5(a) or 5(b), at the
option of the Corporation, (A) the applicable Conversion Price shall be adjusted
for any accrued but unpaid dividends on the Series D Preferred Stock and Series
D-4 Preferred Stock surrendered for conversion, (B) the Corporation shall pay
the holders of the Series D Preferred Stock and Series D-4 Preferred Stock an
amount in cash equal to the accrued but unpaid dividends on the Series D
Preferred Stock or Series D-4 Preferred Stock, as the case may be, surrendered
for conversion or (C) the Corporation may pay the holders of the Series D
Preferred Stock and Series D-4 Preferred Stock an amount in cash less than the
accrued but unpaid dividends on the Series D Preferred Stock and Series D-4
Preferred Stock, as the case may be, surrendered for conversion and the
applicable Conversion Price shall be adjusted by an amount equal to the
difference between the accrued but unpaid dividends and the amount of cash paid
to the holders of the Series D Preferred Stock and Series D-4 Preferred Stock,
as the case may be, pursuant to this clause (C).

               (iii) All shares of Preferred Stock that shall have been
surrendered for conversion as herein provided shall no longer be deemed to be
outstanding and all rights with respect to such shares, including the rights, if
any, to receive notices and to vote, shall immediately cease and terminate on
the Conversion Date, except only the right of the holders thereof to receive
shares of Common Stock in exchange therefor. Any shares of Preferred Stock so
converted shall be retired and canceled and shall not be reissued, and the
Corporation may from time to time take such appropriate action as may be
necessary to eliminate the authorized Preferred Stock or reduce the authorized
number thereof as may be appropriate accordingly.

          (f)  Reservation of Stock Issuable Upon Conversion. The Corporation
shall, at all times when any shares of Preferred Stock shall be outstanding,
reserve and keep available out of its

                                       -19-



authorized but unissued shares of Common Stock, for the purpose of effecting the
conversion of the shares of Preferred Stock, such number of its duly authorized
shares of Common Stock as shall from time to time be sufficient to effect the
conversion of all outstanding shares of Preferred Stock. Before taking any
action that would cause an adjustment reducing the Conversion Price below the
then par value of the shares of Common Stock issuable upon conversion of the
shares of Preferred Stock, the Corporation will take any corporate action which
may, in the opinion of its counsel, be necessary in order that the Corporation
may validly and legally issue fully paid and nonassessable shares of Common
Stock at such adjusted Conversion Price. 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 shares of
Preferred Stock, the Corporation will take such corporate action as may, in the
opinion of its counsel, be necessary to increase its authorized but unissued
shares of Common Stock to such number of shares as shall be sufficient for such
purposes.

          (g)  Adjustments to Conversion Price for Diluting Issues:

               (i)  Special Definitions. For purposes of this Section 5(g), the
following definitions shall apply:

                    (A)  "Option" shall mean rights, options or warrants to
subscribe for, purchase or otherwise acquire Common Stock or Convertible
Securities (as defined below) or restricted stock, excluding options granted to

                                       -20-



C Preferred Stock, Series D Preferred Stock or Series D-1 Preferred Stock
issuable upon exercise of the Excluded Warrants.

                     (C) "Additional Shares of Common Stock" shall mean all
shares of Common Stock issued (or, pursuant to Section 5(g)(iii) below, deemed
to be issued) by the Corporation after the Series D-4 Original Issue Date, other
than:

                         (I)   shares of Common Stock issued or issuable upon
conversion of shares of Preferred Stock (subject to Adjustment);

                         (II)  shares of Common Stock issued or issuable as a
dividend or distribution for which an adjustment to the Conversion Price occurs
pursuant to Section 5(g)(vii);

                         (III) the Reserved Option Shares;

                         (IV)  shares of Company capital stock issued upon
exercise of the Excluded Warrants;

                         (V)   shares of Common Stock issued or issuable upon

                         (VI)  shares of Common Stock issued or issuable by
reason of a dividend, stock split, split-up or other distribution on shares of
Common Stock excluded from the definition of Additional Shares of Common Stock
by the foregoing clauses (I), (II), (III), (IV) (V) or this clause (VI).

               (ii)  No Adjustment of Conversion Price. No adjustment in the
number of shares of Common Stock into which the shares of Preferred Stock are
convertible shall be made, by adjustment in the applicable Conversion Price
thereof pursuant to Section 5(g)(iv) hereof, unless the consideration per share
(determined pursuant to Section 5(g)(v)) for an Additional Share of Common Stock
issued or deemed to be issued by the Corporation (a) is less than the applicable
Conversion Price in effect on the date of, and immediately prior to, the
issuance of such Additional Shares with respect to the Series A Preferred Stock,
Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock
or (b) is less than $1.650286766 per share, subject to Adjustment, immediately
prior to the issuance of such Additional Shares with respect to the Series D-2
Preferred Stock, the Series D-3 Preferred Stock and Series D-4 Preferred Stock.

               (iii) Issuance of Options and Convertible Securities Deemed
Issuance of Additional Shares of Common Stock. If the Corporation at any time or
from time to time after the Original Issue Date shall issue any Options or
Convertible Securities or shall fix a record date for the determination of
holders of any class of securities entitled to receive any such Options or
Convertible Securities, then the maximum number of shares of Common Stock (as
set forth in the instrument relating thereto without regard to any provision
contained therein for a subsequent adjustment of such number) issuable upon the
exercise of such Options or, in the case of Convertible Securities and Options
therefor, the conversion or exchange of such Convertible Securities, shall be
deemed to be Additional Shares of Common Stock issued as of the time of such
issue or, in case such a record date shall have been fixed, as

                                       -21-



of the close of business on such record date, provided, however, that in any
such case in which Additional Shares of Common Stock are deemed to be issued:

                     (A)  no further adjustment in the Conversion Price shall be
made upon the subsequent issue of Convertible Securities or shares of Common
Stock upon the exercise of such Options or conversion or exchange of such
Convertible Securities and, upon the expiration of any such Option or the
termination of any such right to convert or exchange such Convertible
Securities, the Conversion Price then in effect hereunder shall forthwith be
increased to the Conversion Price which would have been in effect at the time of
such expiration or termination had such Option or Convertible Securities, to the
extent outstanding immediately prior to such expiration or termination, never
been issued, and the Common Stock issuable thereunder shall no longer be deemed
to be outstanding; and

                     (B)  if such Options or Convertible Securities by their
terms provide, with the passage of time or otherwise, for any increase in the
consideration payable to the Corporation, or decrease in the number of shares of
Common Stock issuable, upon the exercise, conversion or exchange thereof, the
Conversion Price computed upon the original issue thereof (or upon the
occurrence of a record date with respect thereto), and any subsequent
adjustments based thereon, shall, upon any such increase or decrease becoming
effective, be recomputed to reflect such increase or decrease insofar as it
affects such Options or the rights of conversion or exchange under such
Convertible Securities, provided, however, that no readjustment pursuant to this
clause (B) shall have the effect of increasing the Conversion Price to an amount
which exceeds the lower of (i) the Conversion Price on the original adjustment
date, or (ii) the Conversion Price that would have resulted from any issuance of
Additional Shares of Common Stock between the original adjustment date and such
readjustment date.

               (iv)  Adjustment of Conversion Price Upon Issuance of Additional
Shares of Common Stock. In the event the Corporation shall issue Additional
Shares of Common Stock (including Additional Shares of Common Stock deemed to be
issued pursuant to Section 5(g)(iii) hereof), without consideration or for a
consideration per share that (a) is less than the applicable Conversion Price in
effect on the date of, and immediately prior to, the issuance of such Additional
Shares with respect to the Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock and Series D Preferred Stock or (b) is less than
$1.650286766 per share, subject to Adjustment, immediately prior to the issuance
of such Additional Shares with respect to the Series D-2 Preferred Stock, Series
D-3 Preferred Stock and Series D-4 Preferred Stock, then and in such event, the
applicable Conversion Price shall be reduced, concurrently with such issuance,
to a price (calculated to the nearest hundredth of a cent) computed, with
respect to Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock and Series D Preferred Stock, using the formula set forth below
in item (A) and, with respect to Series D-2 Preferred Stock, Series D-3
Preferred Stock and Series D-4 Preferred Stock, in accordance with item (B)
below.

                                       -22-



                     (A)  The formula for reduction of the applicable Conversion
Price of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred
Stock and Series D Preferred Stock pursuant to this Section 5(g)(iv) is as
follows:

                     Adjusted Conversion Price = (P1xQ1) + (P2xQ2)
                                                 -----------------
                                                      Q1 + Q2

Where: Q1 =  the number of outstanding shares of Common Stock deemed outstanding
             immediately prior to the issuance of the Additional Shares of
             Common Stock;

       Q2 =  the number of Additional Shares of Common Stock issued or deemed to
             be issued by the Corporation without consideration or for a
             consideration per share that is less than the Conversion Price then
             in effect;

       P1 =  the Conversion Price in effect immediately prior to the issuance of
             the Additional Shares of Common Stock; and

       P2 =  the Net Consideration Per Share (as hereinafter defined) received
             by the Corporation as consideration for the issuance of such
             Additional Shares of Common Stock.

For the purpose of this Section 5(g)(iv), (I) all shares of Common Stock
issuable upon conversion of shares of Preferred Stock outstanding immediately
prior to such issue shall be deemed to be outstanding, and (II) immediately
after any Additional Shares of Common Stock are deemed issued pursuant to
Section 5(g)(iii), such Additional Shares of Common Stock shall be deemed to be
outstanding.

                     (B)  Each reduction to the Conversion Price of Series D-2
Preferred Stock, Series D-3 Preferred Stock and Series D-4 Preferred Stock
pursuant to this Section 5(g)(iv) shall be proportionate (i.e., equal to the
same percentage reduction) to each reduction to the Conversion Price of the
Series D Preferred Stock pursuant to this Section 5(g)(iv).

                     (C)  Notwithstanding the foregoing provisions of this
Section 5(g)(iv), there shall be no adjustment to the Conversion Price in
connection with any particular issuance of Additional Shares of Common Stock in
the event that the holders of at least sixty percent (60%) of the Preferred
Stock (acting on an as converted basis as a single class) agree in writing that
such particular issuance of Additional Shares of Common Stock shall not trigger
an adjustment to the Conversion Price.

               (v)   Determination of Consideration. For purposes of this
Section 5(g), the "Net Consideration Per Share" shall mean the per share
consideration received by the Corporation for the issue of any Additional Shares
of Common Stock and shall be computed as follows:

                     (A)  Cash and Property: Such consideration shall:

                          (I)  insofar as it consists of cash, be computed at
the aggregate of cash received by the Corporation, excluding amounts paid or
payable for accrued interest or accrued dividends;

                                       -23-



                          (II)  insofar as it consists of property other than
cash, be computed at the fair market value thereof at the time of such issue, as
determined in good faith by the Board of Directors; and

                          (III) in the event Additional Shares of Common Stock
are issued together with other shares or securities or other assets of the
Corporation for consideration which covers both, be the proportion of such
consideration so received, computed as provided in clauses (I) and (II) above,
as determined in good faith by the Board of Directors (including at least two
(2) Preferred Stock Directors.

                     (B)  Options and Convertible Securities. The Net
Consideration Per Share received by the Corporation for Additional Shares of
Common Stock deemed to have been issued pursuant to Section 5(g)(iii), relating
to Options and Convertible Securities, shall be determined by dividing:

                          (I)  the total amount, if any, received or receivable
by the Corporation as consideration for the issue of such Options or Convertible
Securities, plus the minimum aggregate amount of additional consideration (as
set forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such consideration) payable to
the Corporation upon the exercise of such Options or the conversion or exchange
of such Convertible Securities, or in the case of Options for Convertible
Securities, the exercise of such Options for Convertible Securities and the
conversion or exchange of such Convertible Securities, by

                          (II) the maximum number of shares of Common Stock (as
set forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such number) issuable upon the
exercise of such Options or the conversion or exchange of such Convertible
Securities.

               (vi)  Adjustment for Combinations or Consolidation of Common
Stock. If, at any time after the applicable Original Issue Date the number of
shares of Common Stock outstanding are decreased by a combination of the
outstanding shares of Common Stock, then following the record date fixed for
such combination (or the date of such combination, if no record date is fixed),
the applicable Conversion Price shall be increased so that the number of shares
of Common Stock issuable on conversion of each share of Preferred Stock shall be
decreased in proportion to such decrease in outstanding shares of Common Stock.

               (vii) Adjustment for Stock Dividends, Splits, Etc. If the
Corporation shall at any time after the applicable Original Issue Date fix a
record date for the subdivision, split-up or stock dividend of shares of Common
Stock, then, following the record date fixed for the determination of holders of
shares of Common Stock entitled to receive such subdivision, split-up or
dividend (or the date of such subdivision, split-up or dividend, if no record
date is fixed), the applicable Conversion Price shall be appropriately decreased
so that the number of shares of Common Stock issuable on conversion of each
share of Preferred Stock shall be increased in proportion to such increase in
outstanding shares; provided, however, that the Conversion Price shall not be
decreased at such time if the amount of such reduction would be an amount less
than $.01, but any such amount shall be carried forward and reduction with
respect thereto made at the time of and together with any subsequent reduction
which, together with such amount and any other amount or amounts so carried
forward, shall aggregate $.01 or more.

                                       -24-



               (viii) Adjustment for Merger or Reorganization, Etc. In case of
any consolidation, recapitalization or merger of the Corporation with or into
another corporation or the sale of all or substantially all of the assets of the
Corporation to another corporation (other than a subdivision or combination
provided for elsewhere in this Section 5 and other than a consolidation, merger
or sale which is treated as a Liquidation pursuant to Section 3), each share of
Preferred Stock shall thereafter be convertible into the kind and amount of
shares of stock or other securities or property to which a holder of the number
of shares of Common Stock of the Corporation deliverable upon conversion of such
shares of Preferred Stock would have been entitled upon such consolidation,
merger or sale; and, in such case, appropriate adjustment (as determined in good
faith by the Board of Directors, including at least two (2) Preferred Stock
Directors) shall be made in the application of the provisions in this Section 5
set forth with respect to the rights and interest thereafter of the holders of
the shares of the Preferred Stock, to the end that the provisions set forth in
this Section 5 (including provisions with respect to changes in and other
adjustments of the Conversion Price) shall thereafter be applicable, as nearly
as reasonably may be, in relation to any shares of stock or other property
thereafter deliverable upon the conversion of the shares of Preferred Stock.

               (ix)   Adjustments for Other Dividends and Distributions. If at
any time or from time to time after the applicable Original Issue Date the
Corporation pays a dividend or makes another distribution to the holders of the
Common Stock payable in securities of the Corporation other than shares of
Common Stock, then in each such event provision shall be made so that the
holders of the Series B Preferred Stock, Series C Preferred Stock, Series D
Preferred Stock, Series D-2 Preferred Stock, Series D-3 Preferred Stock and
Series D-4 Preferred Stock shall receive upon conversion thereof, in addition to
the number of shares of Common Stock receivable upon conversion thereof, the

which notice is given) of the Redemption Shares, 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
subsection hereof under which such redemption is being effected, the Redemption
Date or Dates, the applicable Redemption Price, the number of such holder's
shares of Series B Preferred Stock, Series C Preferred Stock, Series D Preferred
Stock or Series D-4 Preferred Stock to be redeemed, the place at which payment
may be obtained and the date on which such holder's conversion rights (as set

earlier than three (3) days' prior to each such Redemption Date) and calling
upon such holder to surrender to the Corporation, in the manner and at the place
designated, the certificate or certificates representing the shares to be
redeemed (the "Redemption Notice").

          (f)   Surrender of Certificates. On or before each designated
Series B, Series C, Series D or Series D-4 Redemption Date, each holder of
Redemption Shares shall (unless such holder has previously exercised his right
to convert such shares into Common Stock as provided in Section 5), surrender
the certificate(s) representing such Redemption Shares to the Corporation, in
the manner and at the place designated in the Redemption Notice, and thereupon

such shares shall be payable to the order of the person whose name appears on

representing the unredeemed shares.

          (g)   Effect of Redemption. If a Redemption Notice shall have been
duly provided in accordance with Section 6(e), and if on the Redemption Date or
Dates the Series B, Series C, Series D, Series D-1 or Series D-4 Redemption
Price as the case may be, is either paid or made available for payment, then
notwithstanding that the certificates evidencing any of the shares of Series B
Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series D-1
Preferred Stock or Series D-4 Preferred Stock so called for redemption shall not
have been surrendered, all dividends with respect to such shares shall cease to
accrue as of each such Redemption Date, such shares shall not thereafter be
transferred on the Corporation's books and all rights of the holders of such
shares with respect to such shares shall terminate as of each such Redemption
Date, except only the right of the holders to receive the Series B, Series C,
Series D, Series D-1 or Series D-4 Redemption Price without interest upon
surrender of their certificate(s) therefor.

                                      -32-



               (h)  Provisions Upon Failure to Redeem. If any shares of Series D
Preferred Stock remain outstanding and the Corporation fails to promptly redeem
shares of Series D Preferred Stock as required by this Section 6, then, until
such time as the failure to redeem is cured (or unless waived by the holders of
at least sixty-six and two-thirds percent (66 2/3%) of the Series D Preferred
Stock), additional dividends shall accrue on the shares of Series D Preferred
Stock at the rate of ten percent (10%) per annum on the Series D Original
Purchase Price, which dividends shall be payable on a quarterly basis regardless
of whether or not declared by the Board of Directors, Holders of Series D
Preferred Stock will have the right to convert any such accrued and unpaid
dividends into shares of Common Stock at the Conversion Price.

         7.    Preemptive Rights. Pursuant to Section 102(b)(3) of the DGCL, the
holders of the Preferred Stock are hereby expressly granted the right to enter
into a separate agreement with the Corporation regarding preemptive rights to
subscribe to any additional issue of stock or other security convertible into
such stock, subject to the terms and conditions of such separate agreement.

         1.    The number of directors  constituting  the Board of Directors of
the Corporation shall be fixed by or in the manner provided herein. The election
of directors need not be by written ballot.

         2.    The Board of Directors is expressly authorized to adopt, amend or
repeal the Bylaws of the Corporation, subject to the right of the stockholders
entitled to vote with respect thereto.

         3.    In furtherance of, and not in limitation of the powers conferred
by statute, the Board of Directors shall have the power to adopt, and to alter,
amend or repeal any provision of this Charter, subject to the right of the
stockholders entitled to vote with respect thereto.

                                  ARTICLE VIII

                             Limitation on Liability

         No director of the Corporation shall be personally liable to the
Corporation or to any stockholder of the Corporation for monetary damages for
breach of fiduciary duty as a director, provided, however, that this provision
shall not limit the liability of a director (i) for any breach of the director's
duty of loyalty to the Corporation or its stockholders, (ii) for acts or
omissions not in good faith or which involved intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the DGCL, or (iv) for any
transaction from which the director derived an improper personal benefit.

         If the DGCL or any other statute of the State of Delaware hereafter is
amended to authorize the further elimination or limitation of the liability of
directors of the corporation, then the liability of a director of the
corporation shall be limited to the fullest extent permitted by the statutes of
the State of Delaware, as so amended, and such elimination or limitation of
liability shall be in addition to, and not in

                                      -33-



lieu of, the limitation on the liability of a director provided by the foregoing
provisions of this Sixth Article.

         Any repeal of or amendment to this Article VIII shall be prospective
only and shall not adversely affect any limitation on the liability of a
director of the Corporation existing at the time of such repeal or amendment.

                                   ARTICLE IX

                                 Indemnification

         To the extent permitted by law, the Corporation shall fully indemnify
any person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding (whether civil,
criminal, administrative or investigative) by reason of the fact that such
person is or was a director or officer of the Corporation, or is or was serving
at the request of the Corporation as a director or officer of another
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise, against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by such person in
connection with such action, suit or proceeding.

         To the extent permitted by law, the Corporation may fully indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding (whether civil,
criminal, administrative or investigative) by reason of the fact that such
person is or was an employee or agent of the Corporation, or is or was serving
at the request of the Corporation as an employee or agent of another
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise, against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by such person in
connection with such action, suit or proceeding.

         The Corporation may advance expenses (including attorneys' fees)
incurred by a director or officer in defending any action, suit, or proceeding
in advance of the final disposition of such action, suit or proceeding upon the
receipt of an undertaking by or on behalf of the director or officer to repay
such amount if it shall ultimately be determined that such director or officer
is not entitled to indemnification. The Corporation may advance expenses
(including attorneys' fees) incurred by an employee or agent in defending any
action, suit, or proceeding in advance of the final disposition of such action,
suit or proceeding upon such terms and conditions, if any, as the Board of
Directors deems appropriate.

                                      -34-



                                    ARTICLE X

                                  Miscellaneous

     1.   The books of the Corporation may (subject to statutory requirements)
be kept outside of the State of Delaware as may be designated by the Board of
Directors, or in the Bylaws of the Corporation.

     2.   This Corporation shall not be governed by Section 203 of the DGCL.
