of Preferred Stock, $0.01 par value per share ("Preferred Stock").

     The following is a statement of the designations and the powers, privileges
and rights, and the qualifications, limitations or restrictions thereof in
respect of each class of capital stock of the Corporation.

A.   COMMON STOCK.
     ------------

     1.   General. The voting, dividend and liquidation rights of the holders of
          -------
the Common Stock are subject to and qualified by the rights of the holders of
the Preferred Stock of any series as may be designated by the Board of Directors
upon any issuance of the Preferred Stock of any series.

     2.   Voting. The holders of the Common Stock are entitled to one vote for
          ------
each share held at all meetings of stockholders (and written actions in lieu of
meetings). There shall be no cumulative voting.

          The number of authorized shares of Common Stock may be increased or
decreased (but not below the number of shares thereof then outstanding) by the
affirmative vote of the holders of a majority of the stock of the Corporation
entitled to vote, irrespective of the provisions of Section 242(b)(2) of the
General Corporation Law of Delaware.

     3.   Dividends. Dividends may be declared and paid on the Common Stock from
          ---------
funds lawfully available therefor as and when determined by the Board of
Directors and subject to any preferential dividend rights of any then
outstanding Preferred Stock.

     4.   Liquidation.  Upon the dissolution or liquidation of the Corporation,
          -----------
whether voluntary or involuntary, holders of Common Stock will be entitled to
receive all assets of the Corporation available for distribution to its
stockholders, subject to any preferential rights of any then outstanding
Preferred Stock.

B.   PREFERRED STOCK.
     ---------------

     Preferred Stock may be issued from time to time in one or more series, each
of such series to have such terms as stated or expressed herein and in the
resolution or resolutions providing for the issue of such series adopted by the
Board of Directors of the Corporation as hereinafter provided.  Any shares of
Preferred Stock which may be redeemed, purchased or acquired by the Corporation
may be reissued except as otherwise provided by law.  Different series of
Preferred Stock shall not be construed to constitute different classes of shares
for the purposes of voting by classes unless expressly provided.

     Authority is hereby expressly granted to the Board of Directors from time
to time to issue the Preferred Stock in one or more series, and in connection
with the creation of any such series, by resolution or resolutions providing for
the issue of the shares thereof, to determine and fix such voting powers, full
or limited, or no voting powers, and such designations, preferences and

                                      -2-


relative participating, optional or other special rights, and qualifications,
limitations or restrictions thereof, including without limitation thereof,
dividend rights, special voting rights, conversion rights, redemption privileges
in liquidation preferences, as shall be stated and expressed in such
resolutions, all to the full extent now or hereafter permitted by the General
Corporation Law of Delaware. Without limiting the generality of the foregoing,
the resolutions providing for issuance of any series of Preferred Stock may
provide that such series shall be superior or rank equally or be junior to the
Preferred Stock of any other series to the extent permitted by law. Except as
otherwise specifically provided in this Certificate of Incorporation, no vote of
the holders of the Preferred Stock or Common Stock shall be a prerequisite to
the issuance of any shares of any series of the Preferred Stock authorized by
and complying with the conditions of this Certificate of Incorporation, the
right to have such vote being expressly waived by all present and future holders
of the capital stock of the Corporation.

C.   CONVERTIBLE PREFERRED STOCK.
     ---------------------------

     7,000,000 shares of the authorized Preferred Stock of the Corporation are
designated Series A Convertible Preferred Stock (the "Series A Preferred
Stock").  4,200,000 shares of the authorized Preferred Stock of the Corporation
are designated Series B Convertible Preferred Stock (the "Series B Preferred
Stock").  6,500,000 shares of the authorized Preferred Stock of the Corporation
are designated Series C Convertible Preferred Stock (the "Series C Preferred
Stock"). 4,900,000 shares of the authorized Preferred Stock of the Corporation
are designated Series D Convertible Preferred Stock (the "Series D Preferred
Stock").  The Series A Preferred Stock, the Series B Preferred Stock, the Series
C Preferred Stock and the Series D Preferred Stock are referred to collectively
as the Convertible Preferred Stock and shall have the following rights,
preferences, powers, privileges and restrictions, qualifications and
limitations.

     1.   Dividends. The Corporation shall not declare or pay any cash on shares
of Common Stock until the holders of the Convertible Preferred Stock then
outstanding shall have first received, or simultaneously receive, a distribution
on each outstanding share of Convertible Preferred Stock, in an amount at least
equal to the product of (i) the per share amount, if any, of the dividends or
other distributions to be declared, paid or set aside for the Common Stock,
multiplied by (ii) the number of whole shares of Common Stock into which such
share of Convertible Preferred Stock is then convertible.

     2.   Liquidation, Dissolution or Winding Up; Certain Mergers,
Consolidations and Asset Sales.

          (a)  In the event of any voluntary or involuntary liquidation,
dissolution or winding up of the Corporation, the holders of shares of
Convertible Preferred Stock then outstanding shall be entitled to be paid out of
the assets of the Corporation available for distribution to its stockholders, by
reason of their ownership thereof, an amount per share equal to $1.00, in the
case of the Series A Preferred Stock, $2.39, in the case of the Series B
Preferred Stock, $6.47, in the case of the Series C Preferred Stock, and $16.35,
in the case of the Series D  Preferred Stock (subject to appropriate adjustment
in the event of any stock dividend, stock split, combination or other similar
recapitalization affecting such shares), plus any dividends declared but unpaid
thereon (the "Liquidation Amount").  If upon any such liquidation, dissolution
or winding up of the Corporation the remaining assets of the Corporation
available for distribution

                                      -3-


to its stockholders shall be insufficient to pay the holders of shares of
Convertible Preferred Stock the full amount to which they shall be entitled, the
holders of shares of Convertible Preferred Stock shall share ratably in any
distribution of the remaining assets and funds of the Corporation in proportion
to the respective amounts which would otherwise be payable in respect of the
shares held by them upon such distribution if all amounts payable on or with
respect to such shares were paid in full.

          (b)  After the payment of all preferential amounts required to be paid
to the holders of Convertible Preferred Stock upon the dissolution, liquidation
or winding up of the Corporation, the holders of shares of Series A Preferred
Stock, Series B Preferred Stock, Series C Preferred Stock, Series D Preferred
Stock and Common Stock then outstanding shall share ratably in the distribution
of the remaining assets and funds of the Corporation in proportion to the number
of shares of Common Stock held by them or issuable upon conversion of shares of
Convertible Preferred Stock held by them (the "Participation Amount"); provided,
however, that if, on an as converted basis, the holders of the Series C
Preferred Stock would receive more than $12.94 per share as their Participation
Amount, then such holders of Series C Preferred Stock shall not be entitled to
receive their Liquidation Amount and shall only be able to receive their
Participation Amount on an as converted basis, and provided further, however,
that if, on an as converted basis, the holders of the Series D Preferred Stock
would receive more than $32.70 per share as their Participation Amount, then
such holders of Series D Preferred Stock shall not be entitled to receive their
Liquidation Amount and shall only be able to receive their Participation Amount
on an as converted basis.

          (c)  Any merger or consolidation of the Corporation into or with
another corporation (except one in which the holders of capital stock of the
Corporation immediately prior to such merger or consolidation continue to hold
at least 66 2/3% by voting power of the capital stock of the surviving
corporation), or the sale of all or substantially all the assets of the
Corporation shall be deemed to be a liquidation of the Corporation, and all
consideration payable to the stockholders of the Corporation (in the case of a
merger or consolidation), or all consideration payable to the Corporation,
together with all other available assets of the Corporation (in the case of an
asset sale), shall be distributed to the holders of capital stock of the
Corporation in accordance with Subsections 2(a) and 2(b) above.  The amount
deemed distributed to the holders of Convertible Preferred Stock upon any such
merger or consolidation shall be the cash or the value of the property, rights
or securities distributed to such holders by the acquiring person, firm or other
entity.  The value of such property, rights or other securities shall be
determined in good faith by the Board of Directors.

     3.   Voting.

          (a)  Each holder of outstanding shares of Convertible Preferred Stock
shall be entitled to the number of votes equal to the number of whole shares of
Common Stock into which the shares of Convertible Preferred Stock held by such
holder are then convertible (as adjusted from time to time pursuant to Section 4
hereof), at each meeting of stockholders of the Corporation (and written actions
of stockholders in lieu of meetings) with respect to any and all matters
presented to the stockholders of the Corporation for their action or
consideration.  Except as required  by law or by the provisions of Subsection
3(b) or Section 7 below or by the provisions establishing any other series of
Preferred Stock, holders of Convertible Preferred

                                      -4-


Stock and of any other outstanding series of stock shall vote together with the
holders of Common Stock as a single class.

          (b)  The holders of record of the shares of Series A Preferred Stock,
exclusively and as a separate class, shall be entitled to elect two members of
the Board of Directors, and the holders of record of the shares of Common Stock
and of any other class or series of voting stock (including the Convertible
Preferred Stock), exclusively and as a separate class, shall be entitled to
elect the balance of the total number of directors of the Corporation.  At any
meeting held for the purpose of electing directors, the presence in person or by
proxy of the holders of a majority of the shares of Series A Preferred Stock
then outstanding shall constitute a quorum of the Series A Preferred Stock for
the purpose of electing directors by holders of the Series A Preferred Stock.  A
vacancy in any directorship filled by the holders of Series A Preferred Stock
shall be filled only by vote or written consent in lieu of a meeting of the
holders of the Series A Preferred Stock or by any remaining director or
directors elected by the holders of Series A Preferred Stock pursuant to this
Subsection 3(b).  The rights of the holders of the Series A Preferred Stock
under this Subsection 3(b) shall terminate on the first date on which there are
issued and outstanding less than 1,750,000 shares of Series A Preferred Stock
(subject to appropriate adjustment in the event of any dividend, stock split,
combination or other similar recapitalization affecting such shares).

          (c)  Subject to the rights of the holders of any series of Preferred
Stock pursuant to the terms of this Certificate of Incorporation or any
resolution or resolutions providing for the issuance of such series of stock
adopted by the Board of Directors, the number of authorized shares of Preferred
Stock may be increased or decreased (but not below the number of shares thereof
then outstanding) by the affirmative vote of the holders of a majority of the
stock of the Corporation entitled to vote generally in the election of directors
irrespective of the provisions of Section 242(b)(2) of the General Corporation
Law of the State of Delaware.

     4.   Optional Conversion.  The holders of the Convertible Preferred
Stock shall have conversion rights as follows (the "Conversion Right");

          (a)  Right to Convert. Each share of Convertible Preferred Stock shall
be convertible, at the option of the holder thereof, at any time and from time
to time, and without the payment of additional consideration by the holder
thereof, into such number of fully paid and nonassessable shares of Common Stock
as is determined by dividing $1.00, in the case of the Series A Preferred Stock,
$2.39, in the case of the Series B Preferred Stock, $6.47 in the case of the
Series C Preferred Stock, and $16.35 in the case of the Series D Preferred
Stock, by the Applicable Conversion Price (as defined below) in effect at the
time of conversion. The "Applicable Conversion Price" shall initially be $0.50,
in the case of the Series A Preferred Stock, $2.39, in the case of the Series B
Preferred Stock, $6.47 in the case of the Series C Preferred Stock, and $16.35
the case of the Series D Preferred Stock, each of which reflects all adjustments
based on events on or prior to September 19, 2000. Such Applicable Conversion
Price, and the rate at which shares of Convertible Preferred Stock may be
converted into shares of Common Stock, shall be subject to adjustment as
provided below.

                                      -5-


     In the event of a notice of redemption of any shares of Convertible
Preferred Stock pursuant to Section 6 hereof, the Conversion Right of the shares
designated for redemption shall terminate at the close of business on the fifth
full day preceding the date fixed for redemption, unless the redemption price is
not paid when due, in which case the Conversion Right for such shares shall
continue until such price is paid in full.  In the event of a liquidation of the
Corporation, the Conversion Right shall terminate at the close of business on
the first day preceding the date fixed for the payment of any amounts
distributable on liquidation to the holders of Convertible Preferred Stock.

          (b)  Fractional Shares. No fractional shares of Common Stock shall be
issued upon conversion of the Convertible Preferred Stock. In lieu of any
fractional shares to which the holder would otherwise be entitled, the
Corporation shall pay cash equal to such fraction multiplied by the then
effective Applicable Conversion Price.

          (c)   Mechanics of Conversion.
               -----------------------

               (i)  In order for a holder of Convertible Preferred Stock to
convert shares of Convertible Preferred Stock into shares of Common Stock, such
holder shall surrender the certificate or certificates for such shares of
Convertible Preferred Stock, at the office of the transfer agent for the
Convertible Preferred Stock (or at the principal office of the Corporation if
the Corporation serves as its own transfer agent), together with written notice
that such holder elects to convert all or any number of the shares of the
Convertible Preferred Stock represented by such certificate or certificates.
Such notice shall state such holder's name or the names of the nominees in which
such holder wishes the certificate or certificates for share of Common Stock to
be issued. If required by the Corporation, certificates surrendered for
conversion shall be endorsed or accompanied by a written instrument or
instruments of transfer, in form satisfactory to the Corporation, duly executed
by the registered holder or his or its attorney duly authorized in writing. The
date of receipt of such certificates and notices by the transfer agent (or by
the Corporation if the Corporation serves as its own transfer agent) shall be
the conversion date ("Conversion Date"). The Corporation shall, as soon as
practicable after the Conversion Date, issue and deliver at such office to such
holder of Convertible Preferred Stock, or to his or its nominees, a certificate
or certificates for the number of shares of Common Stock to which such holder
shall be entitled, together with cash in lieu of any fraction of a share.

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

                                      -6-


               (iii)  Upon any such conversion, no adjustment to the Applicable
Conversion Price shall be made for any declared but unpaid dividends on the
Convertible Preferred Stock surrendered for conversion or on the Common Stock
delivered upon conversion.

               (iv)   All shares of Convertible Preferred Stock which shall have
been surrendered for conversion as herein provided shall no longer be deemed to
be outstanding and all rights with respect to such shares, including the rights,
if any, to receive notices and to vote, shall immediately cease and terminate on
the Conversion Date, except only the right of the holders thereof to receive
shares of Common Stock in exchange therefor and payment of any dividends
declared but unpaid thereon. Any shares of Convertible Preferred Stock so
converted shall be retired and cancelled and shall not be reissued, and the
Corporation (without the need for stockholder action) may from time to time take
such appropriate action as may be necessary to reduce the authorized Convertible
Preferred Stock accordingly.

               (v)    The Corporation shall pay any and all issue and other
taxes that may be payable in respect of any issuance or delivery of shares of
Common Stock upon conversion of shares of Convertible Preferred Stock pursuant
to this Section 4. The Corporation shall not, however, be required to pay any
tax which may be payable in respect of any transfer involved in the issuance and
delivery of shares of Common Stock in a name other than that in which the shares
of Convertible Preferred Stock so converted were registered, and no such
issuance or delivery shall be made unless and until the person or entity
requesting such issuance has paid to the Corporation the amount of any such tax
or has established, to the satisfaction of the Corporation, that such tax has
been paid.

          (d)  Adjustments to Applicable Conversion Price for Diluting Issues:

               (i)  Special Definitions.  For purposes of this Subsection 4(d),
the following definitions shall apply:

                    (A)  "Option" shall mean rights, options or warrants to
subscribe for, purchase or otherwise acquire Common Stock or Convertible
Securities.

                    (B)  "Original Issue Date" shall mean the date on which a
share of the applicable series of Convertible Preferred Stock was first issued.

                    (C)  "Convertible Securities" shall mean any evidences of
indebtedness, shares or other securities directly or indirectly convertible into
or exchangeable for Common Stock.

                    (D)  "Additional Shares of Common Stock" shall mean all
shares of Common Stock issued (or, pursuant to Subsection 4(d)(iii) below,
deemed to be issued) by the Corporation after the Original Issue Date, other
than shares of Common Stock issued or issuable:

                         (I)   upon conversion of any Convertible Securities
                               outstanding on the Original Issue Date, or upon
                               exercise of any Options outstanding on the
                               Original Issue Date;

                                      -7-


                         (II)  as a dividend or distribution on Convertible
                               Preferred Stock;

                         (III) by reason of a dividend, stock split, split-up or
                               other distribution on shares of Common Stock that
                               is covered by Subsections 4(e) or 4(f) below; or

                         (IV)  to employees or directors of, or consultants to,
                               the Corporation pursuant to a stock option,
                               restricted stock or other plan or arrangement
                               approved by the Board of Directors, in such
                               amounts only as approved by the Board of
                               Directors or the Compensation Committee of the
                               Board of Directors.

          (ii)   No Adjustments of Applicable Conversion Price. No adjustment in
the number of shares of Common Stock into which the Convertible Preferred Stock
is convertible shall be made, by adjustment in the Applicable Conversion Price
thereof: (a) unless the consideration per share (determined pursuant to
Subsection 4(d)(v)) for an Additional Share of Common Stock issued or deemed to
be issued by the Corporation is less than the Applicable Conversion Price in
effect on the date of, and immediately prior to, the issue of such Additional
Shares, or (b) if prior to such issuance, the Corporation receives written
notice from the holders of at least 67% of the then outstanding shares of the
applicable series of Convertible Preferred Stock (on an as converted basis),
agreeing that no such adjustment shall be made as the result of the issuance of
Additional Shares of Common Stock.

          (iii)  Issue of Securities Deemed Issue of Additional Shares of
Common Stock.

     If the Corporation at any time or from time to time after the Original
Issue Date shall issue any Options or Convertible Securities or shall fix a
record date for the determination of holders of any class of securities entitled
to receive any such Options or Convertible Securities, then the maximum number
of shares of Common Stock (as set forth in the instrument relating thereto
without regard to any provision contained therein for a subsequent adjustment of
such number) issuable upon the exercise of such Options or, in the case of
Convertible Securities and Options therefor, the conversion or exchange of such
Convertible Securities, shall be deemed to be Additional Shares of Common Stock
issued as of the time of such issue or, in the case such a record date shall
have been fixed, as of the close of business on such record date, provided that
Additional Shares of Common Stock shall not be deemed to have been issued unless
the consideration per share (determined pursuant to Subsection 4(d)(v) hereof)
of such Additional Shares of Common Stock would be less than the Applicable
Conversion Price in effect on the date of and immediately prior to such issue,
or such record date, as the case may be, and provided further that in any such
case in which Additional Shares of Common Stock are deemed to be issued:

                                      -8-


               (A)  No further adjustment in the Applicable Conversion Price
shall be made upon the subsequent issue of Convertible Securities or shares of
Common Stock upon the exercise of such Options or conversion or exchange of such
Convertible Securities;

               (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 upon the exercise, conversion or
exchange thereof, the Applicable Conversion Price computed upon the original
issue thereof (or upon the occurrence of a record date with respect thereto),
and any subsequent adjustments based thereon, shall, upon any such increase
becoming effective, be recomputed to reflect such increase insofar as it affects
such Options or the rights of conversion or exchange under such Convertible
Securities;

               (C)  Upon the expiration or termination of any unexercised
Option, the Applicable Conversion Price shall not be readjusted, but the
Additional Shares of Common Stock deemed issued as the result of the original
issue of such Option shall not be deemed issued for the purposes of any
subsequent adjustment of the Applicable Conversion Price;

               (D)  In the event of any change in the number of shares of Common
Stock issuable upon the exercise, conversion, or exchange of any Option or
Convertible Security, including, but not limited to, a change resulting from the
anti-dilution provisions thereof, the Applicable Conversion Price then in effect
shall forthwith be readjusted to such Applicable Conversion Price as would have
obtained had the adjustment which was made upon the issuance of such Option or
Convertible Security not exercised or converted prior to such change been made
upon the basis of such change; and

               (E)  No readjustment pursuant to clause (B) or (D) above shall
have the effect of increasing the Applicable Conversion Price to an amount which
exceeds the lower of (i) the Applicable Conversion Price on the original
adjustment date, or (ii) the Applicable Conversion Price that would have
resulted from any issuances of Additional Shares of Common Stock between the
original adjustment date and such readjustment date.

          (iv)   Adjustment of Applicable Conversion Price Upon Issuance of
Additional Shares of Common Stock.

     In the event the Corporation shall at any time after the Original Issue
Date issue Additional Shares of Common Stock (including Additional Shares of
Common Stock deemed to be issued pursuant to Subsection 4(d)(iii), but excluding
shares issued as a stock split or combination as provided in Subsection 4(e) or
upon a dividend or distribution as provided in Subsection 4(f)), without
consideration or for a consideration per share less than the Applicable
Conversion Price in effect on the date of and immediately prior to such issue,
then and in such event, such Applicable Conversion Price shall be reduced,
concurrently with such issue, to a price (calculated to the nearest cent)
determined by multiplying such Applicable Conversion Price by a fraction, (A)
the numerator of which shall be (1) the number of shares of Common Stock
outstanding immediately prior to such issue plus (2) the number of shares of
Common Stock which the aggregate consideration received or to be received by the
Corporation for the total number of Additional Shares of Common Stock so issued
would purchase at such

                                      -9-


Applicable Conversion Price; and (B) the denominator of which shall be the
number of shares of Common Stock outstanding immediately prior to such issue
plus the number of such Additional Shares of Common Stock so issued; provided
that, for the purpose of this Subsection 4(d)(iv), the number of shares of
Common Stock deemed issuable upon exercise or conversion of such outstanding
Options and Convertible Securities shall not give effect to any adjustments to
the Applicable Conversion Price or conversion rate of such Options or
Convertible Securities resulting from the issuance of Additional Shares of
Common Stock that is the subject of this calculation.

          (v)  Determination of Consideration.  For purposes of this Subsection
4(d), the consideration received by the Corporation for the issue of any
Additional Shares of Common Stock shall be computed as follows:

               (A)  Cash and Property.  Such consideration shall:

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

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

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

               (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 Subsection 4(d)(iii), relating to Options and
Convertible Securities, shall be determined by dividing

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

                                      -10-


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

          (vi)   Multiple Closing Dates. In the event the Corporation shall
issue on more than one date Additional Shares of Common Stock which are
comprised of shares of the same series or class of Preferred Stock, and such
issuance dates occur within a period of no more than 120 days, then the
Applicable Conversion Price shall be adjusted only once on account of such
issuances, with such adjustment to occur upon the final such issuance and to
give effect to all such issuances as if they occurred on the date of the final
such issuance.

     (e)  Adjustment for Stock Splits and Combinations. If the Corporation shall
at any time or from time to time after the Original Issue Date effect a
subdivision of the outstanding Common Stock, the Applicable Conversion Price
then in effect immediately before that subdivision shall be proportionately
decreased. If the Corporation shall at any time or from time to time after the
Original Issue Date combine the outstanding shares of Common Stock, the
Applicable Conversion Price then in effect immediately before the combination
shall be proportionately increased. Any adjustment under this paragraph shall
become effective at the close of business on the date the subdivision or
combination becomes effective.

     (f)  Adjustment for Certain Dividends and Distributions. In the event the
Corporation at any time or from time to time after the Original Issue Date shall
make or issue, or fix a record date for the determination of holders of Common
Stock entitled to receive, a dividend or other distribution payable in
additional shares of Common Stock, then and in each such event the Applicable
Conversion Price for the Convertible Preferred Stock then in effect shall be
decreased as of the time of such issuance or, in the event such a record date
shall have been fixed, as of the close of business on such record date, by
multiplying the Applicable Conversion Price for the Convertible Preferred Stock
then in effect by a fraction:

          (1)  the numerator of which shall be the total number of shares of
     Common Stock issued and outstanding immediately prior to the time of such
     issuance or the close of business on such record date, and

          (2)  the denominator of which shall be the total number of shares of
     Common Stock issued and outstanding immediately prior to the time of such
     issuance or the close of business on such record date plus the number of
     shares of Common Stock issuable in payment of such dividend or
     distribution;

     provided, however, if such record date shall have been fixed and such
dividend is not fully paid or if such distribution is not fully made on the date
fixed therefor, the Applicable Conversion Price for the Convertible Preferred
Stock shall be recomputed accordingly as of the close of business on such record
date and thereafter the Applicable Conversion Price for the Convertible
Preferred Stock shall be adjusted pursuant to this paragraph as of the time of
actual payment of such dividends or distributions; and provided further,
however, that no such adjustment shall be made if the holders of Convertible
Preferred Stock simultaneously receive a dividend or other distribution of
shares of Common Stock in a number equal to the number of

                                      -11-


shares of Common Stock as they would have received if all outstanding shares of
Convertible Preferred Stock had been converted into Common Stock on the date of
such event.

          (g)  Adjustments for Other Dividends and Distributions.  In the event
the Corporation at any time or from time to time after the Original Issue Date
shall make or issue, or fix a record date for the determination of holders of
Common Stock entitled to receive, a dividend or other distribution payable in
securities of the Corporation other than shares of Common Stock, then and in
each such event provisions shall be made so that the holders of the Convertible
Preferred Stock shall receive upon conversion thereof in addition to the number
of shares of Common Stock receivable thereupon, the amount of securities of the
Corporation that they would have received had the Convertible Preferred Stock
been converted into Common Stock on the date of such event and had they
thereafter, during the period from the date of such event to and including the
conversion date, retained such securities receivable by them as aforesaid during
such period, giving application to all adjustments called for during such period
under this paragraph with respect to the rights of the holders of the
Convertible Preferred Stock; and provided further, however, that no such
adjustment shall be made if the holders of Convertible Preferred Stock
simultaneously receive a dividend or other distribution of such securities in an
amount equal to the amount of such securities as they would have received if all
outstanding shares of Convertible Preferred Stock had been converted into Common
Stock on the date of such event.

          (h)  Adjustment for Reclassification Exchange, or Substitution. If the
Common Stock issuable upon the conversion of the Convertible Preferred Stock
shall be changed into the same or a different number of shares of any class or
classes of stock, whether by capital reorganization, reclassification, or
otherwise (other than a subdivision or combination of shares or stock dividend
provided for above, or a reorganization, merger, consolidation, or sale of
assets provided for below), then and in each such event the holder of each such
share of Convertible Preferred Stock shall have the right thereafter to convert
such share into the kind and amount of shares of stock and other securities and
property receivable upon such reorganization, reclassification, or other change,
by holders of the number of shares of Common Stock into which such shares of
Convertible Preferred Stock might have been converted immediately prior to such
reorganization, reclassification, or change, all subject to further adjustment
as provided herein.

          (i)  Adjustment for Merger or Reorganization, etc. In case of any
consolidation or merger of the Corporation with or into another corporation or
the sale of all or substantially all of the assets of the Corporation to another
corporation (other than a consolidation, merger or sale which is covered by
Subsection 2(c)), each share of Convertible Preferred Stock shall thereafter be
convertible (or shall be converted into a security which shall be convertible)
into the kind and amount of shares of stock or other securities or property to
which a holder of the number of shares of Common Stock of the Corporation
deliverable upon conversion of such Convertible Preferred Stock would have been
entitled upon such consolidation, merger or sale; and, in such case, appropriate
adjustments (as determined in good faith by the Board of Directors) shall be
made in the application of the provisions in this Section 4 set forth with
respect to the rights and interest thereafter of the holders of the Convertible
Preferred Stock, to the end that the provisions set forth in this Section 4
(including provisions with respect to changes in and other adjustments of the
Applicable Conversion Price) shall

                                      -12-


thereafter be applicable, as nearly as reasonably may be, in relation to any
shares of stock or other property thereafter deliverable upon the conversion of
the Convertible Preferred Stock.

          (j)  No Impairments. The Corporation will not, by amendment of its
Certificate 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
Section 4 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
Convertible Preferred Stock against impairment.

          (k)  Certificate as to Adjustments.  Upon the occurrence of each
adjustment or readjustment of the Applicable 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 furnish to each holder
of Convertible 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 Convertible Preferred Stock, furnish or cause to be
furnished to such holder a similar certificate setting forth (i) such
adjustments and readjustments, (ii) the Applicable Conversion Price then in
effect, and (iii) the number of shares of Common Stock and the amount, if any,
of other property which then would be received upon the conversion of
Convertible Preferred Stock.

          (l)  Notice of Record Date.  In the event:

               (i)    that the Corporation declares a dividend (or any other
distribution) on its Common Stock payable in Common Stock or other securities of
the Corporation;

               (ii)   that the Corporation subdivides or combines its
outstanding shares of Common Stock;

               (iii)  of any reclassification of the Common Stock of the
Corporation (other than a subdivision or combination of its outstanding shares
of Common Stock or a stock dividend or stock distribution thereon), or if any
consolidation or merger of the Corporation into or with another corporation, or
of the sale of all or substantially all of the assets of the Corporation; or

               (iv)   of the involuntary or voluntary dissolution, liquidation
or winding up of the Corporation;

     then the Corporation shall cause to be filed at its principal office or at
the office of the transfer agent of the Convertible Preferred Stock, and shall
cause to be mailed to the holders of the Convertible Preferred Stock at their
last addresses as shown on the records of the Corporation or such transfer
agent, at least ten days prior to the date specified in (A) below or twenty days
before the date specified in (B) below, a notice stating

                                      -13-


                    (A)  the record date of such dividend, distribution,
subdivision or combination, or, if a record is not to be taken, the date of
which the holders of Common Stock of record to be entitled to such dividend,
distribution, subdivision or combination are to be determined, or

                    (B)  the date on which such reclassification, consolidation,
merger, sale, dissolution, liquidation or winding up is expected to become
effective, and the date as of which it is expected that holders of Common stock
of record shall be entitled to exchange their shares of Common Stock for
securities or other property deliverable upon such reclassification,
consolidation, merger, sale, dissolution or winding up.

     5.   Mandatory Conversion.

          (a)  Upon the earlier of (i) the closing of the sale of shares of
Common Stock, at a price of at least $20.44 per share (subject to appropriate
adjustment for stock splits, stock dividends, combinations and other similar
recapitalizations affecting such shares), in a firm commitment underwritten
public offering of the Corporation's Common Stock pursuant to an effective
registration statement under the Securities Act of 1933, as amended, resulting
in at least $50,000,000 of gross proceeds to the Corporation and any selling
stockholders, or (ii) the written election of the holders of at least 67% of the
then outstanding shares of Series A Preferred Stock (on an as converted basis)
and the Series B Preferred Stock (on an as converted basis), with respect to the
Series A Preferred Stock and the Series B Preferred Stock, the written election
of the holders of at least 75% of the then outstanding shares of Series C
Preferred Stock (on an as converted basis), with respect to the Series C
Preferred Stock, and the written election of the holders of at least 67% of the
then outstanding shares of Series D Preferred Stock (on an as converted basis),
with respect to the Series D Preferred Stock, (A) each outstanding share of such
series of Convertible Preferred Stock shall automatically be converted into such
number of shares of Common Stock as are then issuable upon conversion thereof
pursuant to the provisions of Section 4, and (B) the number of authorized shares
of such series of Preferred Stock shall be automatically reduced by the number
of shares of Preferred Stock that had been designated as Series A Preferred
Stock or Series B Preferred Stock or Series C Preferred Stock or Series D
Preferred Stock, as the case may be, and all provisions included under the
caption "Convertible Preferred Stock", and all references to such series of
Preferred Stock, shall be deleted and shall be of no further force or effect.

          (b)  All holders of record of shares of Convertible Preferred Stock
shall be given written notice of the date on which an automatic conversion will
occur pursuant to Section 5(a) (the "Mandatory Conversion Date") and the place
designated for mandatory conversion of all such shares of Convertible Preferred
Stock.  Such notice need not be given in advance of the occurrence of a
Mandatory Conversion Date.  Such notice shall be sent by first class or
registered mail, postage prepaid, to each record holder of Convertible Preferred
Stock at such holder's address last shown on the records of the transfer agent
for the Convertible Preferred Stock (or the records of the Corporation, if it
serves as its own transfer agent).  Upon receipt of such notice, each holder of
shares of Convertible Preferred Stock shall surrender his or its certificate or
certificates for all such shares to the Corporation at the place designated in
such notice, and shall thereafter receive certificates for the number of shares
of Common Stock to which such holder is entitled pursuant to this Section 5.  On
the Mandatory Conversion Date, all

                                      -14-


rights with respect to the Convertible Preferred Stock so converted, including
the rights, if any, to receive notices and vote (other than as a holder of
Common Stock) will terminate, except only the rights of the holders thereof,
upon surrender of their certificate or certificates therefor, to receive
certificates for the number of shares of Common Stock into which such
Convertible Preferred Stock has been converted. If so required by the
Corporation, certificates surrendered for conversion shall be endorsed or
accompanied by written instrument or instruments of transfer, in form
satisfactory to the Corporation, duly executed by the registered holder or by
his or its attorney duly authorized in writing. As soon as practicable after the
Mandatory Conversion Date and the surrender of the certificate or certificates
for Convertible Preferred Stock, the Corporation shall cause to be issued and
delivered to such holder, or on his or its written order, a certificate or
certificates for the number of full shares of Common Stock issuable on such
conversion in accordance with the provisions hereof and cash as provided in
Subsection 4(b) in respect of any fraction of a share of Common Stock otherwise
issuable upon such conversion.

          (c)  All certificates evidencing shares of Convertible Preferred Stock
which are required to be surrendered for conversion in accordance with the
provisions hereof shall, from and after the Mandatory Conversion Date, be deemed
to have been retired and cancelled and the shares of Convertible Preferred Stock
represented thereby converted into Common Stock for all purposes,
notwithstanding the failure of the holder or holders thereof to surrender such
certificates on or prior to such date.  The Corporation may thereafter take such
appropriate action (without the need for stockholder action) as may be necessary
to reduce the authorized Convertible Preferred Stock accordingly.

     6.   Redemption.

          (a)  The Corporation will, subject to the conditions set forth below,
on July 1, 2004, July 1, 2005 and July 1, 2006 (each, a "Mandatory Redemption
Date"), upon receipt not less than 30 nor more than 120 days prior to the
applicable Mandatory Redemption Date of written request(s) for redemption from
holders of at least a majority of the shares of Convertible Preferred Stock (on
an as converted basis) then outstanding (a "Redemption Request"), redeem from
each requesting holder of shares of Convertible Preferred Stock then
outstanding, at a per share price equal to, in the case of the Series A
Preferred Stock, $1.00 plus an amount equal to 8% thereon per annum from the
Original Issue Date to the applicable Mandatory Redemption Date, in the case of
the Series B Preferred Stock, $2.39 plus an amount equal to 8% thereon per annum
from the Original Issue Date to the applicable Mandatory Redemption Date, in the
case of the Series C Preferred Stock, $6.47 plus an amount equal to 8% thereon
per annum from the Original Issue Date to the applicable Mandatory Redemption
Date, and in the case of the Series D Preferred Stock, $16.35 plus an amount
equal to 8% thereon per annum from the Original Issue Date to the applicable
Mandatory Redemption Date (the "Mandatory Redemption Price"), the following
respective portions of the number of shares of Convertible Preferred Stock held
by such requesting holder set forth opposite the applicable Mandatory Redemption
Date:

                            Portion of Shares of
     Mandatory          Convertible Preferred Stock
  Redemption Date              To be Redeemed
  ---------------          --------------------

     July 1, 2004                   33 1/3%
     July 1, 2005                     50%
     July 1, 2006            All Shares then held

                                      -15-


          (b)  If the funds of the Corporation legally available for redemption
of Convertible Preferred Stock on any Mandatory Redemption Date are insufficient
to redeem the number of shares of Convertible Preferred Stock required under
this Section 6 to be redeemed on such date, those funds which are legally
available will be used to redeem the maximum possible number of such shares of
Convertible Preferred Stock ratably on the basis of the number of shares of
Convertible Preferred Stock which would be redeemed on such date if the funds of
the Corporation legally available therefor had been sufficient to redeem all
shares of Convertible Preferred Stock required to be redeemed on such date.  At
any time thereafter when additional funds of the Corporation become legally
available for the redemption of Convertible Preferred Stock, such funds will be
used, at the end of the next succeeding fiscal quarter, to redeem, to the extent
of the available funds, the balance of the shares which the Corporation was
theretofore obligated to redeem.

          (c)  Unless there shall have been a failure to pay the Mandatory
Redemption Price with respect to shares of Convertible Preferred Stock requested
to be redeemed on a Mandatory Redemption Date, on such Mandatory Redemption Date
all rights of the holder of such shares as a stockholder of the Corporation by
reason of the ownership of such share will cease, except the right to receive
the Mandatory Redemption Price of such share, without interest, upon
presentation and surrender of the certificate representing such share, and such
share will not from and after such Mandatory Redemption Date be deemed to be
outstanding.

          (d)  Any Convertible Preferred Stock redeemed pursuant to this Section
6 will be cancelled and will not under any circumstances be reissued, sold or
transferred and the Corporation may from time to time take such appropriate
action as may be necessary to reduce the authorized Convertible Preferred Stock
accordingly.

     7.   Negative Covenants.

          (a)  So long as at least 1,750,000 shares of Series A Preferred Stock,
1,100,000 shares of Series B Preferred Stock, 1,500,000 shares of Series C
Preferred Stock or 1,225,000 shares of Series D Preferred Stock are outstanding,
the Corporation shall not, without the prior written consent of the holders of
at least 67% of the then outstanding shares of Convertible Preferred Stock,
acting as a single class (on an as converted basis):

               (i)    Authorize any class or series of stock having preference
or priority over, or on a parity with, the Convertible Preferred Stock as to
dividends or liquidation;

               (ii)   Amend the Corporation's Certificate of Incorporation;

               (iii)  Declare or pay any dividends on Common Stock other than
dividends payable solely in Common Stock;

               (iv)   Repurchase shares of Common Stock at a price greater than
the price at which they were originally issued;

                                      -16-


               (v)    Liquidate or wind-up the Corporation;

               (vi)   Make any loan or advance to any person, including without
limitation, any employee or director of the Corporation or any subsidiary,
except advances and similar expenditures in the ordinary course of business or
under the terms of an employee stock or option plan approved by the Board of
Directors;

               (vii)  (A)  Merge with or into or consolidate with any other
corporation; (B) sell, lease, or otherwise dispose of all or substantially all,
or a Significant Portion (as defined below), of its properties or assets, or (C)
acquire all or substantially all of the properties or assets of any other
corporation or entity (except for consideration of less than 20% of the
Corporation's consolidated net worth as of the end of the prior fiscal quarter).
For the purposes of this Certificate of Incorporation, "Significant Portion"
shall mean properties or assets with a fair market value equal to more than 35%
of the book value of the Corporation's total properties or assets as of the end
of the most recent fiscal quarter;

               (viii) Incur indebtedness for borrowed money in excess of
$150,000, unless such amount is approved by the Board of Directors; or

               (ix)   Increase the number of directors of the Corporation to
more than six.

     SEVENTH:  Whenever a compromise or arrangement is proposed between this
corporation and its creditors or any class of them and/or between this

way of this corporation or of any creditor or stockholder thereof or on the
