and restated to read in full as follows:

                                   ARTICLE II

        The address of the Corporation's registered office in the State of

                                   ARTICLE IV

        (A) CLASSES OF STOCK. The Corporation is authorized to issue two classes
of stock to be designated, respectively, "Common Stock" and "Preferred Stock."
The total number of shares which the Corporation is authorized to issue is Sixty
Million Five Hundred Thousand (60,500,000) each with a par value of $0.001 per
share. Forty Three Million (43,000,000) shall be Common Stock and Seventeen
Million Five Hundred Thousand (17,500,000) shall be Preferred Stock.

        (B) RIGHTS, PREFERENCES AND RESTRICTIONS OF PREFERRED STOCK. The
Preferred Stock authorized by this Fifth Amended and Restated Certificate of
Incorporation may be issued from time to time in one or more series. The first
series of Preferred Stock shall be designated "Series A Preferred Stock" and
shall consist of One Million Six Hundred Twenty Thousand



   2

(1,620,000) shares. The second series of Preferred Stock shall be designated
"Series B Preferred Stock" and shall consist of Three Million Six Hundred
Thousand (3,600,000) shares. The third series of Preferred Stock shall be

        The remaining shares of Preferred Stock may be issued from time to time
in one or more series. The Board of Directors of the corporation (the "Board of
Directors") is expressly authorized to provide for the issue of all or any of
the remaining shares of Preferred Stock in one or more series, and to fix the
number of shares and to determine or alter for each such series, such voting
powers, full or limited, or no voting powers, and such designations,
preferences, and relative, participating, optional, or other rights and such
qualifications, limitations, or restrictions thereof, as shall be stated and
expressed in the resolution or resolutions adopted by the Board of Directors
providing for the issue of such shares (a "Preferred Stock Designation") and as
may be permitted by the General Corporation Law of the State of Delaware. The
Board of Directors is also expressly authorized to increase or decrease (but not
below the number of shares of such series then outstanding) the number of shares
of any series other than the Series A, Series B, Series C or Series D Preferred
Stock subsequent to the issue of shares of that series. In case the number of
shares of any such series shall be so decreased, the shares constituting such
decrease shall resume the status that they had prior to the adoption of the
resolution originally fixing the number of shares of such series.The rights,
preferences, privileges, and restrictions granted to and imposed on the Series A
Preferred Stock, the Series B Preferred Stock, Series C Preferred Stock and the
Series D Preferred Stock are as set forth below in this Article IV(B).

               1. DIVIDEND PROVISIONS. The holders of shares of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D
Preferred Stock shall be entitled to receive dividends, out of any assets
legally available therefor, contemporaneously as to each other and prior and in
preference to any declaration or payment of any dividend (payable other than in
Common Stock or other securities and rights convertible into or entitling the
holder thereof to receive, directly or indirectly, additional shares of Common
Stock) on the Common Stock of the Corporation, at the rate as follows: (a)
holders of the Series A Preferred Stock shall be entitled to receive dividends
at an annual rate of $0.04 per share of Series A Preferred Stock; (b) holders of
the Series B Preferred Stock shall be entitled to receive dividends at an annual
rate of $0.115 per share of Series B Preferred Stock; (c) holders of the Series
C Preferred Stock shall be entitled to receive dividends at an annual rate of
$0.04994 per share of Series C Preferred Stock; and (d) holders of the Series D
Preferred Stock shall be entitled to receive dividends at an annual rate of $
0.9261 per share (in each case adjusted to reflect subsequent stock dividends,
stock splits or recapitalizations) when, as and if declared by the Board of
Directors. Such dividends shall not be cumulative.

               2. LIQUIDATION.

                      (a) PREFERENCE. In the event of any liquidation,
dissolution or winding up of the Corporation, either voluntary or involuntary,
the holders of the Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock and Series D Preferred Stock shall be


                                      -2-
   3

entitled to receive, prior and in preference to any distribution of any of the
assets of the Corporation to the holders of Common Stock by reason of their
ownership thereof, an amount per share equal to $0.50, $1.43955, $0.55626 and
$10.29, respectively, per share (as adjusted for any stock dividends,
combinations or splits with respect to such shares), plus declared but unpaid
dividends on such shares. If, upon the occurrence of such event, the assets and
funds thus distributed among the holders of the Preferred Stock shall be
insufficient to permit the payment to such holders of the full aforesaid
preferential amounts, then the entire assets and funds of the Corporation
legally available for distribution shall be distributed ratably among the
holders of the Preferred Stock in proportion to the preferential amounts which
would be payable in respect of the shares held by them upon such distribution if
all amounts payable on or with respect to said shares were paid in full.

                      (b) REMAINING ASSETS. Upon the completion of the
distribution required by Section 2(a) above, the remaining assets of the
Corporation available for distribution to stockholders shall be distributed on a
pro rata basis to the holders of Common Stock based on the number of shares of
Common Stock held by each.

                      (c) CERTAIN ACQUISITIONS.

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

                             (ii) VALUATION OF CONSIDERATION. In the event of a
deemed liquidation as described in Section 2(c)(i) above, if the consideration
received by the Corporation is other than cash, its value will be deemed its
fair market value. Any securities shall be valued as follows:

                                    (A) Securities not subject to investment
letter or other similar restrictions on free marketability:

                                            (1) If traded on a securities
exchange or the Nasdaq National Market, the value shall be deemed to be the
average of the closing prices of the securities on such exchange over the
thirty-day period ending three (3) days prior to the closing;

                                            (2) If actively traded
over-the-counter, the value shall be deemed to be the average of the closing bid
or sale prices (whichever is applicable) over the thirty-day period ending three
(3) days prior to the closing; and


                                      -3-
   4

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

                                    (B) The method of valuation of securities
subject to investment letter or other restrictions on free marketability (other
than restrictions arising solely by virtue of a stockholder's status as an
affiliate or former affiliate) shall be to make an appropriate discount from the
market value determined as above in Section 2(c)(ii)(A) to reflect the
approximate fair market value thereof, as mutually determined by the Corporation
and the holders of at least a majority of the voting power of all then
outstanding shares of Preferred Stock.

                             (iii) NOTICE OF TRANSACTION. 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
such impending transaction not later than ten (10) days prior to the
stockholders' meeting called to approve such transaction, or ten (10) days prior
to the closing of such transaction, whichever is earlier, and shall also notify
such holders in writing of the final approval of such transaction. The first of
such notices shall describe the material terms and conditions of the impending
transaction and the provisions of this Section 2, and the Corporation shall
thereafter give such holders prompt notice of any material changes. The
transaction shall in no event take place sooner than ten (10) days after the
Corporation has given the first notice provided for herein or sooner than ten
(10) days after the Corporation has given notice of any material changes
provided for herein; provided, however, that such periods may be shortened upon
the written consent of the holders of each class of Preferred Stock that are
entitled to such notice rights or similar notice rights and that represent at
least a majority of the voting power of all then outstanding shares of such
series of Preferred Stock.

                             (iv) EFFECT OF NONCOMPLIANCE. In the event the
requirements of this Section 2(c) are not complied with, the Corporation shall
forthwith either cause the closing of the transaction to be postponed until such
requirements have been complied with, or cancel such transaction, in which event
the rights, preferences and privileges of the holders of the Series A Preferred
Stock, the Series B Preferred Stock, the Series C Preferred Stock and the Series
D Preferred Stock shall revert to and be the same as such rights, preferences
and privileges existing immediately prior to the date of the first notice
referred to in Section 2(c)(iii) hereof.

               3. REDEMPTION. The Preferred Stock is not redeemable.

               4. CONVERSION. The holders of Preferred Stock shall have
conversion rights as follows (the "Conversion Rights"):

                      (a) RIGHT TO CONVERT. Subject to Section 4(c), each share
of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock
and Series D 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 stock, into such number of fully
paid and nonassessable shares of Common Stock as is determined by dividing (i)
$0.50, in the case of the Series A Preferred Stock; (ii) $1.43955, in the case
of the Series B Preferred


                                      -4-
   5

Stock; (iii) $0.55626 in the case of the Series C Preferred Stock; and (iv)
$10.29 in the case of the Series D Preferred Stock, by the Conversion Price
applicable to such share, determined as hereafter provided, in effect on the
date the certificate is surrendered for conversion. The initial Series A
Conversion Price shall be $0.50 per share, the initial Series B Conversion Price
shall be $1.43955 per share, the initial Series C Conversion Price shall be
$0.55626 per share and the initial Series D Conversion Price shall be $10.29.
The Series A Conversion Price, the Series B Conversion Price, the Series C
Conversion Price and the Series D Conversion Price shall each be subject to
adjustment as set forth in Section 4(d).

                      (b) AUTOMATIC CONVERSION. Each share of Series A Preferred
Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred
Stock shall automatically be converted into shares of Common Stock at the Series
A Conversion Price, the Series B Conversion Price, the Series C Conversion Price
and the Series D Conversion Price, as applicable, at the time in effect for such
share immediately upon the earlier of (i) except as provided below in Section
4(c), the Corporation's sale of its Common Stock in a firm commitment
underwritten public offering pursuant to a registration statement under the
Securities Act of 1933, as amended, resulting in aggregate gross offering
proceeds to the Corporation (before expenses, discounts or commissions) of at
least $20,000,000 and an offering price of not less than $15.44 per share (as
adjusted for any stock dividends, combinations or splits with respect to such
shares) or (ii) the date specified by written consent or agreement of the
holders of a majority of the then outstanding shares of Series A Preferred
Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred
Stock voting together as a single class.

                      (c) MECHANICS OF CONVERSION. Before any holder of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D
Preferred Stock shall be entitled to convert the same into shares of Common
Stock, he shall surrender the certificate or certificates therefor, duly
endorsed, at the office of the Corporation or of any transfer agent for the
Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or
Series D Preferred Stock (as the case may be), and shall give written notice to
the Corporation at its principal corporate office, of the election to convert
the same and shall state therein the name or names in which the certificate or
certificates for shares of Common Stock are to be issued. 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 Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock or Series D 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. In the
event of an automatic conversion pursuant to Section 4(b), the outstanding
shares of the Series A Preferred Stock, the Series B Preferred Stock, the Series
C Preferred Stock and the Series D Preferred Stock shall be converted
automatically without any further action by the holder of such shares and
whether or not the certificates representing such shares are surrendered to the
Corporation or the transfer agent for the Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock or Series D Preferred Stock (as the
case may be); and the Corporation shall not be obliged to issue certificates
evidencing the shares of Common Stock issuable upon such automatic conversion
unless the certificates evidencing the shares of Series A Preferred Stock, the
Series B Preferred Stock, the Series C Preferred Stock and the Series D


                                      -5-
   6

Preferred Stock are either delivered to the Corporation or the transfer agent
for the Series A Preferred Stock, Series B Preferred Stock, Series C Preferred
Stock or Series D Preferred Stock (as the case may be) as provided above, or the
holder notifies the Corporation or the transfer agent for the Series A Preferred
Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred
Stock (as the case may be) 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. The Corporation shall, as soon as practicable thereafter, issue
and deliver to such address as the holder may direct, a certificate or
certificates for the number of shares of Common Stock to which such holder shall
be entitled. If the conversion is in connection with a public offering of
securities described in Section 4(b), the conversion shall be conditioned upon
the closing with the underwriters of the sale of securities pursuant to such
offering, and the conversion shall not be deemed to have occurred until
immediately prior to the closing of such sale of securities.

                      (d) CONVERSION PRICE ADJUSTMENTS OF PREFERRED STOCK FOR
CERTAIN SPLITS AND COMBINATIONS. The Series A Conversion Price, the Series B
Conversion Price, the Series C Conversion Price and the Series D Conversion
Price shall be subject to adjustment from time to time as follows:

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

                             (ii) If the number of shares of Common Stock
outstanding at any time after the Purchase Date is decreased by a combination of
the outstanding shares of Common Stock, then, following the record date of such
combination, the Series A Conversion Price, the Series B Conversion Price, the
Series C Conversion Price and the Series D Conversion Price shall be
appropriately increased so that the number of shares of Common Stock issuable on
conversion of each share of such series shall be decreased in proportion to such
decrease in outstanding shares.


                                      -6-
   7

                      (e) OTHER DISTRIBUTIONS. In the event the Corporation
shall declare a distribution payable in securities of other persons, evidences
of indebtedness issued by the Corporation or other persons, assets (excluding
cash dividends) or options or rights not referred to in Section 4(d)(i), then,
in each such case for the purpose of this Section 4(e), the holders of Series A
Preferred Stock, the Series B Preferred Stock, the Series C Preferred Stock and
the Series D Preferred Stock shall be entitled to a proportionate share of any
such distribution as though they were the holders of the number of shares of
Common Stock of the Corporation into which their shares of Preferred Stock are
convertible as of the record date fixed for the determination of the holders of
Common Stock of the Corporation entitled to receive such distribution.

                      (f) RECAPITALIZATIONS. If at any time or from time to time
there shall be a recapitalization of the Common Stock (other than a subdivision,
combination or merger or sale of assets transaction provided for elsewhere in
this Section 4 or in Section 2), provision shall be made so that the holders of
the Series A Preferred Stock, the Series B Preferred Stock, the Series C
Preferred Stock and the Series D Preferred Stock shall thereafter be entitled to
receive upon conversion of the Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock or the Series D Preferred Stock the number of
shares of stock or other securities or property of the Corporation or otherwise,
to which a holder of Common Stock deliverable upon conversion would have been
entitled on such recapitalization. In any such case, appropriate adjustment
shall be made in the application of the provisions of this Section 4 with
respect to the rights of the holders of the Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock and the Series D Preferred Stock after
the recapitalization to the end that the provisions of this Section 4 (including
adjustment of the Conversion Price then in effect and the number of shares
purchasable upon conversion of the Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock and Series D Preferred Stock) shall be
applicable after that event and be as nearly equivalent as practicable.

                      (g) NO IMPAIRMENT. The Corporation will not, by amendment
of its Certificate of Incorporation or through any reorganization,
recapitalization, transfer of assets, consolidation, merger, dissolution, issue
or sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed
hereunder by the Corporation, but will at all times in good faith assist in the
carrying out of all the provisions of this Section 4 and in the taking of all
such action as may be necessary or appropriate in order to protect the
Conversion Rights of the holders of Preferred Stock against impairment.

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

                             (i) No fractional shares shall be issued upon the
conversion of any share or shares of the Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock or Series D Preferred Stock, and the
number of shares of Common Stock to be issued shall be rounded to the nearest
whole share. Whether or not fractional shares are issuable upon such conversion
shall be determined on the basis of the total number of shares of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D
Preferred Stock the holder


                                      -7-
   8

is at the time converting into Common Stock and the number of shares of Common
Stock issuable upon such aggregate conversion.

                             (ii) Upon the occurrence of each adjustment or
readjustment of the Series A Conversion Price, the Series B Conversion Price,
the Series C Conversion Price and the Series D Conversion Price pursuant to this
Section 4, the Corporation, at its expense, shall promptly compute such
adjustment or readjustment in accordance with the terms hereof and prepare and
furnish to each holder of Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock and Series D Preferred Stock 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 Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock or Series D Preferred Stock, furnish
or cause to be furnished to such holder a like certificate setting forth (A)
such adjustment and readjustment, (B) the Series A Conversion Price, the Series
B Conversion Price, the Series C Conversion Price and the Series D Conversion
Price at the time in effect, and (C) 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 a share of the Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock or Series D Preferred Stock

                      (i) NOTICES OF RECORD DATE. In the event of any taking by
the Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, the Corporation
shall mail to each holder of Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock and Series D Preferred Stock, at least ten (10) days
prior to the date specified therein, a notice specifying the date on which any
such record is to be taken for the purpose of such dividend, distribution or
right, and the amount and character of such dividend, distribution or right.

                      (j) RESERVATION OF STOCK ISSUABLE UPON CONVERSION. The
Corporation shall at all times reserve and keep available out of its authorized
but unissued shares of Common Stock, solely for the purpose of effecting the
conversion of the shares of the Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock and Series D Preferred Stock, such number of its
shares of Common Stock as shall from time to time be sufficient to effect the
conversion of all outstanding shares of Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock and Series D Preferred Stock; and if
at any time the number of authorized but unissued shares of Common Stock shall
not be sufficient to effect the conversion of all then outstanding shares of
Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and
Series D Preferred Stock, in addition to such other remedies as shall be
available to the holder of such 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, including, without limitation, engaging
in best efforts to obtain the requisite stockholder approval of any necessary
amendment to this Certificate of Incorporation.

                      (k) NOTICES. Any notice required by the provisions of this
Section 4 to be given to the holders of shares of Series A Preferred Stock,
Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock
shall be deemed given if deposited in the United States mail, postage prepaid,
and addressed to each holder of record at his address appearing on the books of
the Corporation.

               5. VOTING RIGHTS.

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

                      (b) VOTING FOR THE ELECTION OF DIRECTORS. The Board of
Directors will consist of seven (7) members, two (2) of which will be elected by
the holders of a majority of the shares of the Common Stock, voting as a
separate class, one (1) of which will be elected by the holders of a majority of
