Series A Preferred Stock shall be entitled to receive dividends at the rate of
$0.08 per share (as adjusted for any combinations or splits with respect to such
shares) per annum, payable out of funds legally available therefor. Such
dividends shall be cumulative and shall accrue on each share from day to day,
commencing on the date of issuance of such share, whether or not earned or
declared. Subject to paragraphs 1E, 1F, 1G, 1J and 1K below, accrued dividends
shall be payable quarterly, in arrears, on each March 31, June 30, September 30
and December 31 (each, a "Quarterly Dividend Reference Date"), commencing on the
first Quarterly Dividend Reference Date following June 30, 1999, and shall be
payable in cash (except as provided in part 5), when, and if, paid.

     1.B. Subject to paragraphs 1E, 1F, 1J and 1K below, the holders of Series B
Preferred Stock shall be entitled to receive dividends at the rate of $0.08 per
share (as adjusted for any combinations or splits with respect to such shares)
per annum, payable out of funds legally available therefor. Such dividends shall

                                       2



arrears, on each Quarterly Dividend Reference Date, commencing on the first
Quarterly Dividend Reference Date following June 30, 1999, and shall be payable
in cash (except as provided in part 5), when, and if, paid.

     1.C. Subject to paragraphs 1E, 1J and 1K below, the holders of Series C
Stock shall be entitled to receive dividends on each share of Series C Stock
held by such person at the Applicable Series C Dividend Rate Per Share (as
defined in part 8) (as adjusted for any combinations or splits with respect to
such shares), payable out of funds legally available therefor. Such dividends
shall accrue during each year at the Applicable Series C Dividend Rate Per Share
on a daily basis from and including the date of issuance of such share of Series
C Stock to and including the date on which the Series C Liquidation Value and/or
Series C-1 Liquidation Value, as the case may be, of such share is paid. Such
dividends shall accrue whether or not they have been declared and whether or not
there are profits, surplus or other funds of the corporation legally available
for the payment of dividends; provided, however, in the event that (i) all
accrued but unpaid dividends in respect of the Series C Preferred Stock are paid
in accordance with paragraphs 1L or 5L of these Articles of Incorporation and
(ii) the Series C-1 Preferred Stock is redeemed in accordance with paragraph 3E
of these Articles of Incorporation, the holders of Series C Preferred Stock
shall be entitled to receive dividends on each share of Series C Stock held by
such person at the Applicable Revised Series C Dividend Rate Per Share (as
defined in part 8) (as adjusted for any combinations or splits with respect to
such shares) and the provisions of this paragraph shall apply to the Applicable
Revised Series C Dividend Rate Per Share as if it were the Applicable Series C
Dividend Rate for the purposes thereof. Such dividends shall be cumulative such
that all accrued and unpaid dividends shall be fully paid or declared with funds
irrevocably set apart for payment before any dividend, distribution or payment
may be made with respect to any Series A Preferred Stock, Series B Preferred
Stock, Common Stock or any other series or class of capital stock of the
corporation (other than the Series D Preferred Stock). The Series D-1 Original
Issue Date shall be deemed to be the "date of issuance" of each share of Series
C Stock regardless of the number of times transfer of each such share is made on
the stock records maintained by or for the corporation and regardless of the
number of certificates which may be issued to evidence each such share. Subject
to paragraphs 1E, 1J and 1K below, accrued dividends shall be payable quarterly,
in arrears, on each Quarterly Dividend Reference Date, commencing on the first
Quarterly Dividend Reference Date following June 30, 2001, and shall be payable
in cash, when, and if, paid.

Series D Preferred Stock shall accrue on a daily basis at the rate of 13.5% per
annum of the sum of the Series D Liquidation Price (as defined in paragraph
2A(i)) plus all accumulated and unpaid dividends thereon, from and including the
date of issuance of such share of Series D Preferred Stock to and including the
date on which the Series D Liquidation Value (as defined in paragraph 2A(i)) of
such share is paid or, in the case of each share of Series D-1 Preferred Stock,
the date on which such share is converted into Series D-2 Preferred Stock and
Class A Common Stock. Such dividends shall accrue whether or not they have been
declared and whether or not there are profits, surplus or other funds of the
corporation legally available for the payment of dividends. Such dividends shall
be cumulative such that all accrued and unpaid dividends shall be fully paid or
declared with funds irrevocably set apart for payment before any dividend,
distribution or payment may be made with respect to any Series A Preferred
Stock, Series B Preferred Stock,

                                       3



Series C Stock, Common Stock or any other series or class of capital stock of
the corporation. The date on which the corporation initially issues any shares
of Series D-1 Preferred Stock shall be deemed to be the "date of issuance" of
(i) such share of Series D-1 Preferred Stock and (ii) the share of Series D-2
Preferred Stock into which such share of Series D-1 Preferred Stock is converted
hereunder in order that, without duplication, the accumulated and/or accrued and
unpaid dividends on any share of Series D-1 Preferred Stock that is converted
into a share of Series D-2 Preferred Stock will be deemed to be accumulated
and/or accrued on such share of Series D-2 Preferred Stock, in each case
regardless of the number of times transfer of each such share is made on the
stock records maintained by or for the corporation and regardless of the number
of certificates which may be issued to evidence each such share. To the extent
not paid on each April 30 and October 31 (each, a "Semi-Annual Dividend
Reference Date"), commencing on the first Semi-Annual Dividend Reference Date
following May 1, 2001, all dividends which have accrued on each share of Series
D Preferred Stock during the six-month period (or other period in the case of
the initial Semi-Annual Dividend Reference Date after the date of issuance of
such share) ending upon each such Semi-Annual Dividend Reference Date shall be
accumulated and shall remain accumulated and accrued dividends with respect to
such share of Series D Preferred Stock until paid. Dividends accruing on the
Series D Preferred Stock shall be payable solely in cash and not in kind, when,
and if, paid.

     1.E. No dividends or other distributions (whether in cash, securities or
other property, other than dividends paid on shares of Common Stock and
consisting solely of shares of Common Stock of the same class) shall be paid on
or declared and set apart for any Series A Preferred Stock, Series B Preferred
Stock, Series C Stock, Common Stock or any other series or class of capital
stock of the corporation (other than Series D Preferred Stock) at any time when
any Series D Preferred Stock is outstanding.

     1.F. Subject to paragraph 1E above, no dividends or other distributions
(whether in cash, securities or other property, other than dividends paid on
shares of Common Stock and consisting solely of shares of Common Stock of the
same class) shall be paid on or declared and set apart for any Series A
Preferred Stock or Series B Preferred Stock or any other series or class of
capital stock of the corporation (other than the Series D Preferred Stock) on
any Quarterly Dividend Reference Date until dividends in the total amount due on
such date to holders of the Series C Stock, including any dividends that have
accumulated but remain unpaid, shall have been paid or declared and set apart
for payment on or prior to such Quarterly Dividend Reference Date.

     1.G. Subject to paragraphs 1E and 1F above, no dividends or other
distributions (whether in cash, securities or other property, other than
dividends paid on shares of Common Stock and consisting solely of shares of
Common Stock of the same class) shall be paid on or declared and set apart for
any Series A Preferred Stock on any Quarterly Dividend Reference Date until
dividends in the total amount due on such date to holders of the Series B
Preferred Stock, including any dividends that have accumulated but remain
unpaid, shall have been paid or declared and set apart for payment on or prior
to such Quarterly Dividend Reference Date.

     1.H. Subject to paragraphs 1E, 1F and 1G above, no dividends or other
distributions (other than dividends paid on shares of Common Stock and
consisting solely of shares of Common Stock of the same class) shall be paid on
or declared and set apart for any Common

                                       4



Stock or any other class or series of stock of the corporation during any fiscal
year of the corporation until dividends in the total amount of $0.08 per share
(as adjusted for any combinations or splits with respect to such shares) on the
Series A Preferred Stock, $0.08 per share (as adjusted for any combinations or
splits with respect to such shares) on the Series B Preferred Stock, in respect
of each share of Series C Stock, the Applicable Series C Dividend Rate Per Share
or Applicable Revised Series C Dividend Rate Per Share, as the case may be (each
as adjusted for any combinations or splits with respect to such shares), and, in
respect of each share of Series D Preferred Stock, 13.5% per annum of the sum of
the Series D Liquidation Price, plus in each case all accumulated and unpaid
dividends thereon, shall have been paid or declared and set apart for payment
during that fiscal year and any prior year in which dividends have accumulated
but remain unpaid, and no dividends shall be paid on any share of Common Stock
(other than dividends paid on shares of Common Stock and consisting solely of
shares of Common Stock of the same class) unless a dividend (including the
amount of any dividends paid pursuant to the above provisions of this paragraph
1H, in the case of Series A Preferred Stock and Series C Stock only) or other
distribution is paid with respect to all outstanding shares of Series A
Preferred Stock, Series C Preferred Stock and Series D-1 Preferred Stock in an
amount for each such share of Series A Preferred Stock, Series C Preferred Stock
or Series D-1 Preferred Stock, as the case may be, equal to or greater than the
aggregate amount of such dividends or other distributions for the number of
shares of Common Stock into which each outstanding share of Series A Preferred
Stock, Series C Preferred Stock and Series D-1 Preferred Stock could then be
converted.

     1.I. Subject to paragraph 1E above, in the event the corporation shall
declare a distribution (other than any distribution described in paragraphs 1A
through 1D and 1F through 1H) payable in securities of the corporation or other
Persons (other than dividends paid on shares of Common Stock and consisting
solely of shares of Common Stock of the same class), evidences of indebtedness
issued by the corporation or other Persons, assets (excluding cash dividends) or
options or rights to purchase any such securities or evidences of indebtedness,
and at such time, there are no declared or accrued but unpaid dividends then
owed in respect of any share of Preferred Stock, then, in each such case, the
holders of the outstanding shares of Series A Preferred Stock, Series C
Preferred Stock and Series D-1 Preferred Stock shall be entitled to receive a
proportionate share of any such distribution as though the holders of the
outstanding shares of Series A Preferred Stock, Series C Preferred Stock and
Series D-1 Preferred Stock were the holders of the number of shares of Common
Stock into which the outstanding shares of Series A Preferred Stock, Series C
Preferred Stock and Series D-1 Preferred Stock could be converted as of the
record date fixed for the determination of the holders of Common Stock of the
corporation entitled to receive such distribution.

     1.J. The corporation may elect not to pay dividends under paragraphs 1A,
1B, 1C or 1D (i) if a Default or Event of Default is then continuing under the
Credit Agreement, or (ii) to the extent the payment of dividends pursuant to
paragraph 1A, 1B, 1C or 1D would cause a Default or Event of Default under the
Credit Agreement to occur; provided, that if the corporation elects to suspend
the payment of dividends under this paragraph 1J, dividends shall continue to
accrue pursuant to this part 1 and shall be payable out of funds legally
available therefor immediately after no Default or Event of Default is then
continuing under the Credit Agreement, and to the extent the corporation may pay
such dividends without causing a Default

                                       5



or Event of Default of Section 6 of the Credit Agreement. A Default or Event of
Default will not be "continuing" if it has been waived.

     1.K. The corporation shall not pay cash dividends under paragraphs 1A, 1B,
1C or 1D at any time when any of the Notes are outstanding; provided, that if
the corporation is not permitted to pay dividends as a result of this paragraph
1K, dividends shall continue to accrue pursuant to this part 1 and shall be
payable pursuant to this part 1 out of funds legally available therefor at the
time when no Notes remain outstanding.

     1.L. Subject to paragraph 1E above, immediately prior to, or concurrently
with, the closing of the Initial Public Offering, the corporation shall declare
and pay a dividend to the holders of the Series C Preferred Stock in an amount
equal to the aggregate amount of all declared or accrued but unpaid dividends in
respect of the Series C Preferred Stock.

     Part 2. Liquidation Preference.

     2.A. In the event of any liquidation, dissolution or winding up of the
corporation, either voluntary or involuntary:

          (i) The holders of the Series D Preferred Stock shall be entitled to
     receive, prior and in preference to any distribution of any of the assets
     or surplus funds of the corporation to the holders of the Series A
     Preferred Stock, Series B Preferred Stock, Series C Stock, Common Stock or
     any other capital stock of the corporation by reason of their ownership
     thereof (the "Series D Liquidation Preference"), (a) an amount for each
     share of Series D-1 Preferred Stock then held by them equal to $1,000.00
     (as adjusted for any combinations or splits with respect to such shares)
     (the "Series D-1 Liquidation Price") plus accrued or declared but unpaid
     dividends on such share of Series D-1 Preferred Stock (together with the
     Series D-1 Liquidation Price, the "Series D-1 Liquidation Value" of such
     share) and (b) an amount for each share of Series D-2 Preferred Stock then
     held by them equal to the sum of (1) $1,000.00 minus the product of $0.01
     and the number of shares of Class A Common Stock issued along with the
     issuance of such share of Series D-2 Preferred Stock at the time of the
     conversion of the share of Series D-1 Preferred Stock which was converted
     into such share of Series D-2 Preferred Stock and shares of Class A Common
     Stock and (2) the product of $0.01 and the number of shares of Class A
     Common Stock issued along with the issuance of such share of Series D-2
     Preferred Stock at the time of the conversion of the share of Series D-1
     Preferred Stock which was converted into such share of Series D-2 Preferred
     Stock and shares of Class A Common Stock (as adjusted for any combinations
     or splits with respect to such shares) (such sum being the "Series D-2
     Liquidation Price") plus accrued or declared but unpaid dividends on such
     share of Series D-2 Preferred Stock (together with the Series D-2
     Liquidation Price, the "Series D-2 Liquidation Value" of such share) (the
     Series D-1 Liquidation Price and Series D-2 Liquidation Price shall be
     referred to in these Articles of Incorporation as the "Series D Liquidation
     Price" and the Series D-1 Liquidation Value and Series D-2 Liquidation
     Value shall be referred to in these Articles of Incorporation as the
     "Series D Liquidation Value"). If upon the occurrence of such event, the
     assets and funds thus distributed among the holders of the Series D
     Preferred Stock shall be insufficient to permit the payment to such holders
     of such full preferential

                                       6



     amount, then the entire assets and funds of the corporation legally
     available for distribution shall be distributed ratably among the holders
     of the Series D Preferred Stock in proportion to the Series D Liquidation
     Value of the shares of Series D Preferred Stock then held by them.

          (ii) After payment to the holders of the Series D Preferred Stock of
     the full amount to which they are entitled under subparagraph (i) above,
     the holders of the Series C Stock shall be entitled to receive, prior and
     in preference to any distribution of any of the assets or surplus funds of
     the corporation to the holders of the Series A Preferred Stock, Series B
     Preferred Stock, Common Stock or any other capital stock of the corporation
     by reason of their ownership thereof (the "Series C Liquidation
     Preference"), (a) an amount for each share of Series C Preferred Stock then
     held by them equal to the greater of (i) $19.689579 (as adjusted for any
     combinations or splits with respect to such shares) plus declared or
     accrued but unpaid dividends on such share of Series C Preferred Stock and
     (ii) the amount each share of Series C Preferred Stock would be entitled
     pro rata, together with the Series A Preferred Stock, the Series D-1
     Preferred Stock, the Common Stock and any other securities entitled to
     participate with the Common Stock in liquidation, assuming conversion into
     the largest number of full shares of Common Stock into which such share of
     Series C Preferred Stock could be converted (pursuant to the provisions of
     part 5 of these Articles of Incorporation), had all shares of Series C
     Preferred Stock been converted at the date fixed for such liquidation,
     dissolution or winding up of the corporation (such greater amount being the
     "Series C Preferred Liquidation Value" of such share) and (b) an amount for
     each share of Series C-1 Preferred Stock then held by them equal to
     $19.689579 (as adjusted for any combinations or splits with respect to such
     shares) plus declared or accrued but unpaid dividends on such share of
     Series C-1 Preferred Stock (the "Series C-1 Liquidation Value" of such
     share) (the Series C Preferred Liquidation Value and the Series C-1
     Liquidation Value shall be referred to in these Articles of Incorporation
     as the "Series C Liquidation Value"). If upon the occurrence of such event,
     the assets and funds thus distributed among the holders of the Series C
     Stock shall be insufficient to permit the payment to such holders of such
     full preferential amount, then the entire assets and funds of the
     corporation legally available for distribution shall be distributed ratably
     among the holders of the Series C Stock in proportion to the Series C
     Preferred Liquidation Value or Series C-1 Liquidation Value, as the case
     may be, of the shares of Series C Stock then held by them.

          (iii) After payment to the holders of the Series D Preferred Stock and
     the Series C Stock of the full amount to which they are entitled under
     subparagraphs (i) and (ii) above, the holders of the Series B Preferred
     Stock shall be entitled to receive, prior and in preference to any
     distribution of any of the assets or surplus funds of the corporation to
     the holders of the Series A Preferred Stock, Common Stock or any other
     capital stock of the corporation by reason of their ownership thereof (the
     "Series B Liquidation Preference"), an amount for each share of Series B
     Preferred Stock then held by them equal to $1.00 (as adjusted for any
     combinations or splits with respect to such shares) plus accrued or
     declared but unpaid dividends on such share of Series B Preferred Stock
     (the "Series B Liquidation Value" of such share). If upon the occurrence of
     such event, the assets and funds thus distributed among the holders of the
     Series B Preferred

                                       7



     Stock shall be insufficient to permit the payment to such holders of such
     full preferential amount, then the entire assets and funds of the
     corporation legally available for distribution shall be distributed ratably
     among the holders of the Series B Preferred Stock in proportion to the
     shares of Series B Preferred Stock then held by them.

          (iv) After payment to the holders of the Series D Preferred Stock, the
     Series C Stock and the Series B Preferred Stock of the full amount to which
     they are entitled under subparagraphs (i), (ii) and (iii) above, the
     holders of the Series A Preferred Stock shall be entitled to receive, prior
     and in preference to any distribution of any of the assets or surplus funds
     of the corporation to the holders of the Common Stock or any other capital
     stock of the corporation by reason of their ownership thereof (the "Series
     A Liquidation Preference"), an amount for each share of Series A Preferred
     Stock then held by them equal to $1.00 (as adjusted for any combinations or
     splits with respect to such shares) plus accrued or declared but unpaid
     dividends on such share of Series A Preferred Stock (the "Series A
     Liquidation Value" of such share). If upon the occurrence of such event,
     the assets and funds thus distributed among the holders of the Series A
     Preferred Stock shall be insufficient to permit the payment to such holders
     of such full preferential amount, then the entire assets and funds of the
     corporation legally available for distribution shall be distributed ratably
     among the holders of the Series A Preferred Stock in proportion to the
     shares of Series A Preferred Stock then held by them.

          (v) Subject to the payment in full of the Series D Liquidation
     Preference, the Series C Liquidation Preference, the Series B Liquidation
     Preference and the Series A Liquidation Preference as provided in
     subparagraphs (i), (ii), (iii) and (iv) above, all remaining assets and
     surplus funds of the corporation shall be distributed among holders of
     Common Stock and the holders of Series A Preferred Stock and Series D-1
     Preferred Stock, ratably in proportion to the shares of Common Stock then
     held by them and the shares of Common Stock into which the shares of Series
     A Preferred Stock and Series D-1 Preferred Stock then held by them could be
     converted.

     2.B. For purposes of this part 2, a "liquidation" shall, at the option of
both (i) the holders of at least 66-2/3% of the outstanding shares of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and, if
clause (ii) of this paragraph does not apply, Series D Preferred Stock, voting
together as a single class and not as separate classes or series, and (ii) if,
as a result of any such transaction deemed to be a "liquidation" for purposes of
this part 2, the holders of Series D Preferred Stock would receive any
consideration other than cash or would receive cash consideration in an
aggregate amount that is less than the aggregate Series D Liquidation Value for
all shares of Series D Preferred Stock, the holders of at least 66-2/3% of the
outstanding shares of Series D Preferred Stock, voting as a separate class,
include:

               (a) a consolidation or merger of the corporation with or into any
          other corporation, or any other Person, other than a wholly-owned
          Subsidiary of the corporation, excluding any transaction in which
          shareholders of the corporation prior to the transaction will maintain
          voting control of the resulting entity after the transaction;

                                       8



               (b) any corporate reorganization in which the corporation shall

          in the absence of such agreement, by an independent appraisal paid for
          by the corporation; and

          (ii) Securities subject to investment letter or other restrictions on
     free marketability shall be valued at an appropriate discount from the fair
     market value determined as above in subparagraphs (i)(a), (i)(b) or (i)(c)

Stock ratably among the holders of the shares to be redeemed based upon the
aggregate Series A Redemption Price of such shares held by each such holder. At
any time and from time to time thereafter when additional funds of the
corporation are legally available for redemption of shares of Series A Preferred
Stock, such funds immediately will be applied to redeem the balance of the

Redemption Price, the Series B Redemption Price, the Series C Redemption Price,
the Series C-1 Redemption Price, the Series D-2 Redemption Price or the

Preferred Stock, Series C Stock or Series D Stock represented by any certificate
are redeemed, a new certificate representing the number of unredeemed shares of
Series A Preferred Stock, Series B Preferred Stock, Series C Stock or Series D

voting as separate series and not as a single class, the corporation shall not
make any amendment to these Articles of Incorporation or the corporation's

Secretary of State containing any provisions, which would increase the number of
authorized shares of the Series A Preferred Stock, Series B Preferred Stock,

not as a single class, the corporation shall not purchase, redeem or otherwise
acquire or retire for value any of its capital stock or other equity securities
or declare or make any dividend or other distribution with respect to any of its
capital stock or other equity securities (other than a dividend or distribution
payable solely in shares of Common Stock), except that this provision shall not

     The holders of Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock and Series D-1 Preferred Stock shall have conversion rights as
follows (the "Conversion Rights"):

     5.A. Right to Convert. Subject to the provisions of paragraph 5C, (i) each
share of Series A Preferred Stock shall be convertible, at the option of the
holder thereof, at any time after the date of issuance of such share, at the
office of the corporation or any transfer agent for such share, into such number
of fully paid and nonassessable shares of Class A Common Stock as is determined
by dividing $1.00 by the Series A Conversion Price (as defined below) in effect
at the time of conversion, (ii) each share of Series B Preferred Stock shall be
convertible, at the option of the holder thereof, concurrently with the closing
of a Qualified Public Offering with respect to the Series B Preferred Stock, at
the office of the corporation or any transfer agent for such share, into such
number of fully paid and nonassessable shares of Class A Common Stock as is
determined by dividing the Series B Redemption Price at the time of closing of
such Qualified Public Offering by the Qualified Public Offering Price Per Share,
(iii) each share of Series C Preferred Stock shall be convertible, at the option
of the holder thereof, (a) at any time after the expiration of the Additional
Financing Period, (b) during the Additional Financing Period, concurrently with
upon the closing of a Qualified Public Offering with respect to the Series C
Preferred Stock or (c) during the Additional Financing Period, concurrently with
the closing of a sale of Triggering Securities (as defined in the Co-Sale
Agreement) but in the case of this clause (c) only if the holder has elected to
sell shares of Common Stock at such closing and then only to the extent
necessary so that the holder holds the number of shares of Common Stock to be
sold at such closing, at the office of the corporation or any transfer agent for
such share, into such number of fully paid and nonassessable shares of Class A
Common Stock as is determined by dividing $19.689579 by the Series C Conversion
Price (as defined below) in effect at the time of conversion, and (iv) each
share of Series D-1 Preferred Stock shall be convertible, at the option of the
holder thereof, (a) at any time after the expiration of the Additional Financing
Period, (b) during the Additional Financing Period, concurrently with the
closing of a Qualified Public Offering with respect to the Series D Preferred
Stock or (c) during the Additional Financing Period, concurrently with the
closing of a sale of Triggering Securities (as defined in the Co-Sale Agreement)
but in the case of this clause (c) only if the holder has elected to sell shares
of Common Stock at such closing and then only to the extent necessary so that
the holder holds the number of shares of Common Stock to be sold at such
closing, at the office of the corporation or any transfer agent for such share,
into (1) one fully paid and nonassessable share of Series D-2 Preferred Stock
and (2) a quantity of fully paid and nonassessable shares of Class A Common
Stock equal to the Series D-1 Conversion Amount in effect at the time of
conversion. Shares of Series C-1 Preferred Stock and Series D-2 Preferred Stock
shall not be convertible.

     5.B. Automatic Conversion. Each share of Series A Preferred Stock shall
automatically be converted into shares of Class A Common Stock at the then
effective Series A

                                       18



Conversion Price immediately upon the closing of a Qualified Public Offering
with respect to the Series A Preferred Stock. Each share of Series C Preferred
Stock shall automatically be converted into shares of Class A Common Stock at
the then effective Series C Conversion Price immediately upon the closing of a
Qualified Public Offering with respect to the Series C Preferred Stock. Each
share of Series D-1 Preferred Stock shall automatically be converted into (i)
one fully paid and nonassessable share of Series D-2 Preferred Stock and (ii) a
quantity of fully paid and nonassessable shares of Class A Common Stock equal to
the Series D-1 Conversion Amount in effect at the time of conversion immediately
upon the closing of a Qualified Public Offering with respect to the Series D
Preferred Stock.

     5.C. Mechanics of Conversion. Before (i) any holder of Series A Preferred
Stock, Series B Preferred Stock or Series C Preferred Stock shall be entitled to
convert shares of Series A Preferred Stock, Series B Preferred Stock or Series C
Preferred Stock into shares of Class A Common Stock or (ii) any holder of Series
D-1 Preferred Stock shall be entitled to convert shares of Series D-1 Preferred
Stock into shares of Series D-2 Preferred Stock and shares of Class A Common
Stock, such holder shall surrender the certificate or certificates therefor,
duly endorsed, at the office of the corporation or of any transfer agent for
such shares, and shall give written notice to the corporation at such office
that such holder elects to convert the same and shall state therein the name or
names in which the certificate or certificates for shares of Series D-2
Preferred Stock and/or Class A Common Stock, as applicable, are to be issued.
The corporation shall, as soon as practicable thereafter, issue and deliver at
such office to such holder of Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock or Series D-1 Preferred Stock a certificate or
certificates for the number of shares of Series D-2 Preferred Stock and/or Class
A Common Stock, as applicable, to which the holder shall be entitled as
aforesaid. Such conversion shall be deemed to have been made immediately prior
to the close of business on the date of surrender of the shares of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series
D-1 Preferred Stock to be converted, and the Person or Persons entitled to
receive the shares of Series D-2 Preferred Stock and/or Class A Common Stock, as
applicable, issuable upon such conversion shall be treated for all purposes as
the record holder or holders of such shares of Series D-2 Preferred Stock and/or
Class A Common Stock, as applicable, on such date. In the event of an automatic
conversion of the Series A Preferred Stock, Series C Preferred Stock or Series
D-1 Preferred Stock, the Board of Directors may elect to treat the conversion of
the shares of Series A Preferred Stock, Series C Preferred Stock or Series D-1
Preferred Stock as having been made effective as of the date of the event
resulting in the automatic conversion.

     5.D. Adjustments to Conversion Prices and the Series D Dilution Factor for
Dilutive Issues.

          (i) Conversion Prices and Series D Dilution Factor. The initial Series
     A Conversion Price shall be $1.00 per share. The initial Series C
     Conversion Price shall be $19.689579 per share. The initial Series D
     Dilution Factor shall be an amount equal to 1.00. The Series A Conversion
     Price, the Series C Conversion Price and the Series D Dilution Factor shall
     be subject to adjustment as set forth in this part 5.

                                       19

               excess of 1,114,181 shares of Common Stock (subject to adjustment
               for all combinations and splits), in the aggregate (any such
               securities issued in excess of such amount shall be deemed
               Additional Shares of Common Stock), in one or more Third Party
               Financings;

provided, however, that (A) shares of Common Stock deemed to be issued pursuant

the Series C Conversion Price (as provided in

                                       20



5(D)(viii)), (B) on or prior to the date of the expiration of the Additional
Financing Period only, the issuance of shares of Common Stock (or, pursuant to
paragraph 5D(iv), shares of Common Stock deemed to be issued) as described in
subparagraph (c)(7) shall be deemed to be an issuance of Additional Shares of
Common Stock for the purposes of determining any adjustments to the Series A
Conversion Price and the Series C Conversion Price, (C) the issuance of shares
of Common Stock (or, pursuant to paragraph 5D(iv), shares of Common Stock deemed
to be issued) as described in subparagraph (c)(2) (but only to the extent such
shares are issued or deemed to be issued to an Eligible Employee), subparagraph
(c)(3) and subparagraph (c)(4) shall be deemed to be an issuance of Additional
Shares of Common Stock for purposes of determining any adjustment to the Series
D Dilution Factor, and (D) on or prior to the date of the expiration of the
Additional Financing Period only, the issuance of shares of Common Stock (or,
pursuant to paragraph 5D(iv), shares of Common Stock deemed to be issued) as
described in subparagraph (c)(2) (but only to the extent such shares are issued
or deemed to be issued to an Eligible Employee), subparagraph (c)(3),
subparagraph (c)(4) and subparagraph (c)(7) shall be deemed to be an issuance of
Additional Shares of Common Stock for purposes of determining the number of
Fully Diluted Shares of Common Stock.

          (iii) No Adjustment of Conversion Price or Series D Dilution Factor.
     No adjustment in the Series A Conversion Price of Series A Preferred Stock
     shall be made in respect of the issuance of Additional Shares of Common
     Stock unless the consideration per share for an Additional Share of Common
     Stock issued or deemed to be issued by the corporation is less than the
     Series A Conversion Price in effect on the date of, and immediately prior
     to such issue. No adjustment in the Series B Conversion Price of Series B
     Preferred Stock shall be made in respect of the issuance of Additional
     Shares of Common Stock. No adjustment in the Series C Conversion Price of
     Series C Preferred Stock shall be made in respect of the issuance of
     Additional Shares of Common Stock unless the consideration per share for an
     Additional Share of Common Stock issued or deemed to be issued by the
     corporation is less than the Series C Conversion Price in effect on the
     date of, and immediately prior to such issue. No adjustment in the Series D
     Dilution Factor shall be made in respect of the issuance of Additional
     Shares of Common Stock unless the consideration per share for an Additional
     Share of Common Stock issued or deemed to be issued by the corporation is
     less than the Market Price of Class A Common Stock determined as of the
     date of such issue.

          (iv) Deemed Issue of Additional Shares of Common Stock. In the event
     the corporation at any time or from time to time after the Series D-1
     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 then entitled to receive any such Options or Convertible
     Securities, then the maximum number of shares (as set forth in the
     instrument relating thereto without regard to any provisions contained
     therein designed to protect against dilution) of Common Stock 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 of the close of business on such record date, provided that in
     any such case in which Additional Shares of Common Stock are deemed to be
     issued:

                                       21



               (a) no further adjustments in the Series A Conversion Price,
          Series C Conversion Price or Series D Dilution Factor 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;

               (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, then the Series A Conversion Price,
          Series C Conversion Price or Series D Dilution Factor 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 such adjustment of
          the Series A Conversion Price, the Series C Conversion Price or Series
          D Dilution Factor shall affect Common Stock previously issued upon
          conversion of Series A Preferred Stock, Series C Preferred Stock or
          Series D-1 Preferred Stock);

               (c) upon the expiration of any such Options (other than any
          Option that is acquired for value by the corporation or a Subsidiary
          or cancelled for value) or any rights of conversion or exchange under
          such Convertible Securities which shall not have been exercised, the
          Series A Conversion Price, Series C Conversion Price or Series D
          Dilution Factor 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 such expiration, be recomputed
          as if:

                    (1) in the case of Convertible Securities or Options for
               Common Stock the only Additional Shares of Common Stock issued
               were the shares of Common Stock, if any, actually issued upon the
               exercise of such Options or the conversion or exchange of such
               Convertible Securities and the consideration received therefor
               was the consideration actually received by the corporation for
               the issue of all such Options, whether or not exercised, plus the
               consideration actually received by the corporation upon such
               exercise, or for the issue of all such Convertible Securities
               which were actually converted or exchanged, plus the additional
               consideration, if any, actually received by the corporation upon
               such conversion or exchange, and

                    (2) in the case of Options for Convertible Securities, only
               the Convertible Securities, if any, actually issued upon the
               exercise thereof were issued at the time of issue of such Options
               and the consideration received by the corporation for the
               Additional Shares of Common Stock deemed to have been then issued
               was the consideration actually received by the corporation for
               the issue of all such Options, whether or not

                                       22



               exercised, plus the consideration deemed to have been received by
               the corporation (determined pursuant to paragraph 5D(ix)) upon
               the issue of the Convertible Securities with respect to which
               such Options were actually exercised;

               (d) no adjustment of the conversion rate for the Series A
          Preferred or Series C Preferred Stock shall have the effect of
          increasing the Series A Conversion Price or Series C Conversion Price
          to an amount which exceeds the lower of (1) the Series A Conversion
          Price or Series C Conversion Price on the original adjustment date, or
          (2) the Series A Conversion Price or Series C Conversion Price that
          would have resulted from any actual issuance of Additional Shares of
          Common Stock between the original adjustment date and such
          readjustment date;

               (e) no adjustment of the Series D Dilution Factor shall have the
          effect of decreasing the Series D Dilution Factor to an amount which
          is lower than the higher of (1) the Series D Dilution Factor on the
          original adjustment date or (2) the Series D Dilution Factor that
          would have resulted from any actual issuance of Additional Shares of
          Common Stock and the operation of any other provision of this part 5
          between the original adjustment date and such readjustment date;

               (f) in the case of any Options that expire by their terms not
          more than 30 days after the date of issue thereof, no adjustment of
          the Series A Conversion Price, the Series C Conversion Price or Series
          D Dilution Factor shall be made, except as to shares of Series A
          Preferred Stock, Series C Preferred Stock or Series D-1 Preferred
          Stock converted during such period, until the expiration or exercise
          of all such Options, whereupon such adjustment shall be made in the
          same manner provided in clause (c) above; and

               (g) if any such record date shall have been fixed and such
          Options or Convertible Securities are not issued on the date fixed
          thereof, the adjustment previously made in the Series A Conversion
          Price, Series C Conversion Price or Series D Dilution Factor that
          became effective on such record date shall be cancelled as of the
          close of business on such record date, and shall instead be made on
          the actual date of issuance, if any.

          (v) Adjustment of Series A Conversion Price Upon Issuance of
     Additional Shares of Common Stock. Subject to subparagraph 5D(viii), in the
     event the corporation, at any time after the Series D-1 Original Issue
     Date, shall issue Additional Shares of Common Stock (including Additional
     Shares of Common Stock deemed to be issued pursuant to paragraph 5D(iv))
     without consideration or for a consideration per share less than the Series
     A Conversion Price in effect on the date of and immediately prior to such
     issue, then and in such event, such Series A Conversion Price shall be
     reduced, concurrently with such issue, to the price (calculated to the
     nearest $0.0001) obtained by multiplying the Series A Conversion Price in
     effect immediately prior to the time of such issue or sale by a fraction,
     the numerator of which shall be (a) the number of shares of Common Stock
     outstanding (or deemed to be outstanding hereunder) immediately prior

                                       23



     to such issue or sale multiplied by the Series A Conversion Price
     immediately prior to such issue or sale plus (b) the consideration received
     (or deemed to be received hereunder) by the corporation upon such issue or
     sale, and the denominator of which shall be the product of (c) the total
     number of shares of Common Stock outstanding (or deemed to be outstanding
     hereunder) immediately after such issue or sale, multiplied by (d) the
     Series A Conversion Price immediately prior to such issue or sale.
     Notwithstanding the foregoing, no adjustment of the Series A Conversion
     Price shall be made in an amount less than $0.0001 per share, but any such
     lesser adjustment shall be carried forward and shall be made at the time of
     and together with the next subsequent adjustment which together with any
     adjustments so carried forward shall amount to $0.0001 per share or more.
     Upon each adjustment of the Series A Conversion Price, the Series A
     Preferred Stock shall thereafter be convertible, at the Series A Conversion
     Price resulting from such adjustment, into the number of shares of Class A
     Common Stock obtained by multiplying the Series A Conversion Price in
     effect immediately prior to such adjustment by the number of shares of
     Class A Common Stock into which the Series A Preferred Stock was
     convertible pursuant hereto immediately prior to such adjustment and
     dividing the product thereof by the Series A Conversion Price resulting
     from such adjustment.

          (vi) Adjustment of Series C Conversion Price Upon Issuance of
     Additional Shares of Common Stock. Subject to subparagraph 5D(viii), in the
     event the corporation, after the Series D-1 Original Issue Date, shall
     issue Additional Shares of Common Stock (including Additional Shares of
     Common Stock deemed to be issued pursuant to paragraph 5D(iv)) without
     consideration or for a consideration per share less than the Series C
     Conversion Price in effect on the date of and immediately prior to such
     issue, then and in such event, such Series C Conversion Price shall be
     reduced, concurrently with such issue, to the price (calculated to the
     nearest $0.0001) obtained by multiplying the Series C Conversion Price in
     effect immediately prior to the time of such issue or sale by a fraction,
     the numerator of which shall be the sum of (a) the number of shares of
     Common Stock outstanding (or deemed to be outstanding hereunder)
     immediately prior to such issue or sale multiplied by the Series C
     Conversion Price immediately prior to such issue or sale plus (b) the
     consideration received (or deemed to be received hereunder) by the
     corporation upon such issue or sale, and the denominator of which shall be
     the product of (c) the total number of shares of Common Stock outstanding
     (or deemed to be outstanding hereunder) immediately after such issue or
     sale, multiplied by (d) the Series C Conversion Price immediately prior to
     such issue or sale. Notwithstanding the foregoing, no adjustment of the
     Series C Conversion Price shall be made in an amount less than $0.0001 per
     share, but any such lesser adjustment shall be carried forward and shall be
     made at the time of and together with the next subsequent adjustment which
     together with any adjustments so carried forward shall amount to $0.0001
     per share or more. Upon each adjustment of the Series C Conversion Price,
     the Series C Preferred Stock shall thereafter be convertible, at the Series
     C Conversion Price resulting from such adjustment, into the number of
     shares of Class A Common Stock obtained by multiplying the Series C
     Conversion Price in effect immediately prior to such adjustment by the
     number of shares of Class A Common Stock into which the Series C Preferred
     Stock was convertible pursuant hereto immediately prior to such adjustment

                                       24



     and dividing the product thereof by the Series C Conversion Price resulting
     from such adjustment.

          (vii) Adjustment of Series D Dilution Factor Upon Issuance of
     Additional Shares of Common Stock. In the event the corporation, at any
     time after the date of the expiration of the Additional Financing Period,
     shall issue Additional Shares of Common Stock (including Additional Shares
     of Common Stock deemed to be issued pursuant to paragraph 5D(iv)) without
     consideration or for a consideration per share less than the Market Price
     of Class A Common Stock determined as of immediately prior to such issue,
     then immediately upon such issue the Series D Dilution Factor shall be
     increased, concurrently with such issue, to the amount (calculated to the
     nearest 0.00001) obtained by multiplying the Series D Dilution Factor in
     effect immediately prior to such issue by a fraction, the numerator of
     which shall be the product derived by multiplying the Market Price of Class
     A Common Stock determined as of immediately prior to such issue by the
     number of shares of Common Stock outstanding (or deemed to be outstanding
     hereunder) immediately after such issue and the denominator of which shall
     be the sum of (1) the number of shares of Common Stock outstanding (or
     deemed to be outstanding hereunder) immediately prior to such issue
     multiplied by the Market Price of Class A Common Stock determined
     immediately prior to such issue, plus (2) the consideration, if any,
     received by the corporation upon such issue. Notwithstanding the foregoing,
     no adjustment of the Series D Dilution Factor shall be made in an amount
     less than 0.00001, but any such lesser adjustment shall be carried forward
     and shall be made at the time of and together with the next subsequent
     adjustment which together with any adjustments so carried forward shall
     amount to 0.00001 or more. Upon each adjustment of the Series D Dilution
     Factor, each share of Series D-1 Preferred Stock shall thereafter be
     convertible into one share of Series D-2 Preferred Stock and a number of
     shares of Class A Common Stock equal to the Series D-1 Conversion Amount
     resulting from such adjustment.

          (viii) Effect of the Issuance of Series D-1 Preferred Stock and
     Changes in the Series D-1 Conversion Amount. The Series A Conversion Price
     shall not be adjusted as a result of the issuance of Series D-1 Preferred
     Stock by the corporation or any change in the Adjusted Series D Underlying
     Common Stock Amount, the Series D Dilution Factor or any component of
     either of them. For purposes of adjusting the Series C Conversion Price
     only, (a) on the Series D-1 Original Issue Date, the corporation will be
     deemed to have issued 2,033,381 Additional Shares of Common Stock, which
     amount is equal to the Initial Series D Underlying Common Stock Amount on
     the Series D-1 Original Issue Date, at the price of $0.01 per share and,
     concurrently with such deemed issuance, the Series C Conversion Price shall
     be reduced to $15.989766 in accordance with the provisions of paragraphs
     5D(iv) (as if the Series D-1 Preferred Stock was a Convertible Security)
     and 5D(vi); (b) in the event the corporation, after the Series D-1 Original
     Issue Date, shall issue Option Shares, then the corporation will be deemed
     to have issued a number of Additional Shares of Common Stock equal to the
     amount by which the Initial Series D Underlying Common Stock Amount, as
     calculated on the date of such issuance immediately following the issuance
     of such Option Shares and after giving effect to the resulting reduction of
     the Series C Conversion Price, exceeds the Initial Series D Underlying
     Common Stock Amount, as calculated on the date of such issuance immediately
     prior to such issuance of Option Shares and without giving effect to such

                                       25



     reduction in the Series C Conversion Price, at the price of $0.01 per share
     and, concurrently with such issuance, the Series C Conversion Price shall
     be reduced in accordance with the provisions of paragraphs 5D(iv) (as if
     the Series D-1 Preferred Stock was a Convertible Security) and 5D(vi); and
     (c) in the event, after the Series D-1 Original Issue Date, the Additional
     Financing Amount increases (other than by reason of the issuance of Option
     Shares), then a number of Additional Shares of Common Stock equal to the
     amount by which the Initial Series D Underlying Common Stock Amount, as
     calculated on the date of such increase immediately prior to such increase
     in the Additional Financing Amount and without giving effect to the
     resulting increase of the Series C Conversion Price, exceeds the Initial
     Series D Underlying Common Stock Amount, as calculated on the date of such
     increase immediately after such increase in the Additional Financing Amount
     and giving effect to such increase in the Series C Conversion Price, shall
     be Additional Shares of Common Stock which were never deemed to have been
     issued as described in clause (a) above and, concurrently with such
     increase in the Additional Financing Amount, the Series C Conversion Price
     shall be increased to reflect such decrease in the Initial Series D
     Underlying Common Stock Amount in accordance with the provisions of
     paragraphs 5D(iv) (as if the Series D-1 Preferred Stock was a Convertible
     Security) and 5D(vi). Except as specifically provided by this paragraph
     5D(viii), the Series C Conversion Price shall not be adjusted as a result
     of the issuance of Series D-1 Preferred Stock by the corporation or any
     change in the Adjusted Series D Underlying Common Stock Amount, the Series
     D Dilution Factor or any component of either of them.

          (ix) Determination of Consideration. For purposes of this paragraph
     5D, the consideration received by the corporation for the issuance of any
     Additional Shares of Common Stock shall be computed as follows:

               (a) Cash and Property. Such consideration shall:

                    (1) insofar as it consists of cash, be computed at the
               aggregate amount of cash received by the corporation excluding
               amounts paid or payable for accrued interest or accrued dividends
               after deducting all commissions and expenses paid and concessions
               and discounts allowed to underwriters, dealers or others
               performing similar services in connection with such issue;

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

                    (3) in the event Additional Shares of Common Stock are
               issued together with other shares or securities or other assets
               of the corporation for consideration that covers both, be the
               proportion of such consideration so received, computed as
               provided in clauses (1) and (2) above, as determined in good
               faith by the Board of Directors.

                                       26



               (b) Options and Convertible Securities. The consideration per
          share received by the corporation for Additional Shares of Common
          Stock deemed to have been issued pursuant to paragraph 5D(iv),
          relating to Options and Convertible Securities, shall be determined by
          dividing:

                    (1) 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 designed to protect against dilution) 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 Option
               for Convertible Securities and the conversion or exchange of such
               Convertible Securities; by

                    (2) the maximum number of shares of Common Stock (as set
               forth in the instruments relating thereto, without regard to any
               provision contained therein designed to protect against dilution)
               issuable upon the exercise of such Options or the conversion or
               exchange of such Convertible Securities.

     5.E. Adjustments for Dividends, Combinations or Subdivisions of Common
Stock. In the event that the corporation at any time or from time to time after
the Series D-1 Original Issue Date shall declare or pay any dividend on the
Common Stock payable in Common Stock or in any right to acquire Common Stock, or
shall effect a subdivision of the outstanding shares of Common Stock into a
greater number of shares of Common Stock (by stock split, reclassification or
otherwise), or in the event the outstanding shares of Common Stock shall be
combined or consolidated, by reclassification or otherwise, into a lesser number
of shares of Common Stock, then, concurrently with the effectiveness of such
event, the Series A Conversion Price and Series C Conversion Price in effect
immediately prior to such event shall be proportionately decreased or increased,
as appropriate, and the Series D Dilution Factor shall be proportionately
increased or decreased, as appropriate.

     5.F. Other Adjustments. In case of any reorganization or any
reclassification of the capital stock of the corporation, any consolidation,
merger or share exchange of the corporation with or into another Person or
Persons (other than a consolidation or merger deemed to be a liquidation,
dissolution or winding up of the corporation as provided in paragraph 2B above),
each share of Series A Preferred Stock, Series C Preferred Stock and Series D-1
Preferred Stock shall thereafter be convertible into the number of shares of
stock or other securities or property (including cash) to which a holder of the
number of shares of Common Stock deliverable upon conversion of such share of
Series A Preferred Stock, Series C Preferred Stock and Series D-1 Preferred
Stock would have been entitled upon the record date of (or date of, if no record
date is fixed) such reorganization, reclassification, consolidation, merger or
share exchange; and, in any case appropriate adjustment (as determined by the
Board of Directors in good faith) shall be made in the application of the
provisions herein set forth with respect to the rights and interests thereafter
of the holders of Series A Preferred Stock, Series B Preferred Stock, Series C

                                       27



Preferred Stock or Series D-1 Preferred Stock to the end that the provisions set
forth herein shall thereafter be applicable, as nearly equivalent as is
practicable, in relation to any shares of stock or the securities or property
(including cash) thereafter deliverable upon the conversion of the shares of
Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or
Series D-1 Preferred Stock.

     5.G. No Impairment. The corporation will not, by amendment of these
Articles of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the corporation but will at
all times in good faith assist in the carrying out of all the provisions of this
part 5 and in the taking of all such action as may be necessary or appropriate
in order to protect the conversion right of the holders of the Series A
Preferred Stock, the Series B Preferred Stock, the Series C Preferred Stock and
the Series D-1 Preferred Stock against impairment.

     5.H. Certificates as to Adjustments. Upon the occurrence of each adjustment
or readjustment of the Series A Conversion Price, Series C Conversion Price or
Series D Dilution Factor pursuant to this part 5, the corporation at its expense
shall promptly compute such adjustment and prepare and furnish to each holder of
Series A Preferred Stock, Series C Preferred Stock or Series D-1 Preferred
Stock, as the case may be, a certificate setting forth such adjustment or
readjustment and showing in detail the facts upon which such adjustment or
readjustment is based. The corporation shall, upon the written request at any
time of any holder of the Series A Preferred Stock or Series C Preferred Stock
or Series D-1 Preferred Stock, furnish or cause to be furnished to such holder a
like certificate setting forth (i) such adjustments and readjustments, (ii) the
Series A Conversion Price, Series C Conversion Price or Series D Dilution
Factor, as the case may be, at the time in effect, and the number of shares of
Common Stock and the amount, if any, of other property which at the time would
be received upon the conversion of the Series A Preferred Stock, Series C
Preferred Stock or Series D-1 Preferred Stock.

     5.I. Issue Taxes. The corporation shall pay any and all issue and other
taxes that may be payable in respect of any issue or delivery of shares of Class
A Common Stock on conversion of shares of Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock or Series D-1 Preferred Stock pursuant
hereto; provided, however, that the corporation shall not be obligated to pay
any transfer taxes resulting from any transfer requested by any holder in
connection with any such conversion.

     5.J. Reservation of Stock Issuable Upon Conversion. The corporation shall
at all times reserve and keep available out of its authorized but unissued
shares of Class A Common Stock, solely for the purpose of effecting the
conversion of the shares of the Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock and Series D-1 Preferred Stock, such number of
its shares of Class A Common Stock as shall from time to time be sufficient to
effect the conversion of all outstanding shares of the Series A Preferred Stock,
Series B Preferred Stock, Series C Preferred Stock and Series D-1 Preferred
Stock and if at any time the number of authorized but unissued shares of Class A
Common Stock shall not be sufficient to effect the conversion of all then
outstanding shares of the Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock and Series D-1 Preferred Stock, the corporation will
take such

                                       28



corporate action as in the opinion of its counsel may be necessary to increase
its authorized but unissued shares of Class A Common Stock to such number of
shares as shall be sufficient for such purpose, including, without limitation,
engaging in best efforts to obtain the requisite shareholder approval of any
necessary amendment to these Articles of Incorporation. The corporation shall at
all times reserve and keep available out of its authorized but unissued shares
of Series D-2 Preferred Stock, solely for the purpose of effecting the
conversion of the shares of the Series D-1 Preferred Stock, such number of its
shares of Series D-2 Preferred Stock as shall from time to time be sufficient to
effect the conversion of all outstanding shares of the Series D-1 Preferred
Stock and if at any time the number of authorized but unissued shares of Series
D-2 Preferred Stock shall not be sufficient to effect the conversion of all then
outstanding shares of the Series D-1 Preferred Stock, the corporation will take
such corporate action as in the opinion of its counsel may be necessary to
increase its authorized but unissued shares of Series D-2 Preferred Stock to
such number of shares as shall be sufficient for such purpose, including,
without limitation, engaging in best efforts to obtain the requisite shareholder
approval of any necessary amendment to these Articles of Incorporation.

     5.K. Fractional Shares. No fractional share shall be issued upon the
conversion of any share or shares of Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock or Series D-1 Preferred Stock. All
shares of Class A Common Stock (including fractions thereof) issuable upon
conversion of more than one share of Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock or Series D-1 Preferred Stock by a
holder thereof shall be aggregated for purposes of determining whether the
conversion would result in the issuance of any fractional share. If, after such
aggregation, the conversion would result in the issuance of a fraction of a
share of Class A Common Stock, the corporation shall, in lieu of issuing any
fractional share, pay the holder otherwise entitled to such fraction a sum in
cash equal to the fair market value of such fraction on the date of conversion
(as determined in good faith by the Board of Directors of the corporation).

     5.L. Payment of Accrued Dividends. Subject to paragraph 1E, (i) as soon as
possible after shares of Series A Preferred Stock have been converted into
shares of Class A Common Stock, the corporation shall deliver to the holder of
the shares of Series A Preferred Stock converted payment in cash in an amount
equal to all accrued and unpaid dividends with respect to each share of Series A
Preferred Stock converted, or if the conversion occurs in connection with a
Qualified Public Offering or following the Initial Public Offering, and the
corporation's securities are then listed on a national securities exchange or
the Nasdaq National Market, at the option of the corporation, (a) in connection
with a Qualified Public Offering, a number of shares of Class A Common Stock as
is determined by dividing the amount of accrued and unpaid dividends on the
shares of Series A Preferred Stock converted concurrently with the closing of
the Qualified Public Offering in question by the Qualified Public Offering Price
Per Share or (b) following the Initial Public Offering, a number of shares of
Class A Common Stock as is determined by dividing the amount of accrued and
unpaid dividends on the shares of Series A Preferred Stock converted at the time
of conversion by the Market Price of a share of Class A Common Stock and (ii) as
soon as possible after shares of Series C Preferred Stock have been converted
into shares of Class A Common Stock, including if the conversion occurs in
connection with a Qualified Public Offering with respect to the Series C
Preferred Stock or following the Initial Public Offering, the corporation shall
deliver to the holder of the shares of Series C Preferred Stock converted
payment in cash in an amount equal to all accrued and unpaid

                                       29



dividends with respect to each share of Series C Preferred Stock converted.
Shares of Class A Common Stock issued by the corporation in payment of accrued
and unpaid dividends in lieu of cash shall, upon issuance, be fully paid and
nonassessable shares.

     5.M. Notices. The corporation shall give each holder of record of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D
Preferred Stock written notice of each proposed underwritten public offering of
Class A Common Stock that could reasonably be anticipated to be a Qualified
Public Offering not later than 20 days prior to the anticipated date of closing
of such public offering. Such notice shall set forth a summary of the proposed
terms of such public offering, including the anticipated Initial Public Offering
Price Per Share (which may be expressed as a range of anticipated prices) for
the Class A Common Stock. Thereafter, the corporation shall give such holders
prompt written notice of any material changes in the proposed terms of such
public offering, including any change in the anticipated Initial Public Offering
Price Per Share. If the public offering is a Qualified Public Offering, the
corporation shall also give each holder of record of Series A Preferred Stock,
Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock
written notice to such effect, specifying the Qualified Public Offering Price
Per Share, not later than the date of the closing of such Qualified Public
Offering.

     Part 6. Registration of Transfers. The corporation will keep at its
principal office a register for the registration of shares of Series A Preferred
Stock, Series B Preferred Stock, Series C Stock, Series D Preferred Stock and
Common Stock. Upon the surrender of any certificate representing shares of
Series A Preferred Stock, Series B preferred Stock, Series C Stock, Series D
Preferred Stock or Common Stock at such place, the corporation will, at the
request of the record holder of such certificate, execute and deliver (at the
corporation's expense) a new certificate or certificates in exchange therefor
representing in the aggregate the number of shares of Series A Preferred Stock,
Series B Preferred Stock, Series C Stock, Series D Preferred Stock or Common
Stock represented by the surrendered certificate. Each such new certificate will
be registered in such name and will represent such number of shares of Series A
Preferred Stock, Series B Preferred Stock, Series C Stock, Series D Preferred
Stock or Common Stock as is requested by the holder of the surrendered
certificate and will be substantially identical in form to the surrendered
certificate, and dividends will accrue on the shares of Series A Preferred
Stock, Series B Preferred Stock, Series C Stock, Series D Preferred Stock or
Common Stock represented by such new certificate from the date to which
dividends have been fully paid on such shares of Series A Preferred Stock,
Series B Preferred Stock, Series C Stock, Series D Preferred Stock represented
by the surrendered certificate.

     Part 7. Replacement.

     Upon receipt of evidence reasonably satisfactory to the corporation (an
affidavit of the registered holder will be satisfactory) of the ownership and
the loss, theft, destruction or mutilation of any certificate evidencing shares
of Series A Preferred Stock, Series B Preferred Stock, Series C Stock, Series D
Preferred Stock or Common Stock, and in the case of any such loss, theft or
destruction, upon receipt of indemnity reasonably satisfactory to the
corporation or, in the case of any mutilation, upon surrender of such
certificate the corporation will (at its expense) execute and deliver in lieu of
such certificate a new certificate of like kind representing the number of
shares of Series A Preferred Stock, Series B Preferred Stock, Series C Stock,

                                       30

reorganization, reclassification, consolidation or merger by a holder of the
number of shares of Class A Common Stock of the corporation into which such
share of Class B Common Stock was convertible immediately prior to such
reorganization, reclassification, consolidation or merger; and, in any such
case, appropriate adjustment shall be made in the application of the provisions
set forth in this paragraph 12E with respect to the rights and interests
thereafter of the holders of Class B Common stock to the end that the provisions
