Stock, Series E-5 Preferred Stock, Series E-6 Preferred Stock and Series E-14 Preferred Stock, (ix) the Series E
Initial Amount applicable to the Series E-7 Preferred Stock, Series E-8 Preferred Stock, Series E-9 Preferred
Stock, Series E-10 Preferred Stock, Series E-11 Preferred Stock, Series E-12 Preferred Stock or Series E-13
Preferred Stock, as the case may be, with respect to each such series of Series E Preferred Stock, and (x) $0.59,
with respect to each share of Series F-1 Preferred Stock (in each case, as appropriately adjusted for any stock
dividends, combinations or splits with respect to the outstanding Preferred Stock), by (y) the Conversion Price
applicable to such share, determined as hereinafter provided, in effect on the date the certificate is
surrendered for conversion in accordance with paragraph (c) of this Section C.1(iv).  The price at which shares
of Common Stock shall be deliverable upon conversion of shares of the Series A Preferred Stock, Series A-1
Preferred Stock, Series B Preferred Stock, Series C-1 Preferred Stock, Series C-2 Preferred Stock, Series C-3
Preferred Stock, Series D Preferred Stock, Series E-1 through Series E-6 and Series E-14 Preferred Stock, Series
E-7 through Series E-13 Preferred Stock, and Series F-1 Preferred Stock (each, a "Conversion Price") shall
initially be (i) $3.00, (ii) $4.00, (iii) $7.00, (iv) $2.17, (v) $3.39, (vi) $3.84, (vii) $1.50, (viii) $1.00,
(ix) the Series E Initial Amount applicable to the shares of the applicable series of Series E Preferred Stock
and (x) $0.59, respectively, per share of Common Stock.  Such initial Conversion Price shall be adjusted as
hereinafter provided.  Immediately following and taking into account the consummation of the purchase and sale of
all of the shares of Series D Preferred Stock, Series D Warrants and Series E Warrants contemplated by the
Securities Purchase Agreement, the Conversion Price for the Series A Preferred Stock, Series A-1 Preferred Stock,
Series B Preferred Stock, Series C-1 Preferred Stock, Series C-2 Preferred Stock and Series C-3 Preferred Stock
shall be: (i) $1.59, (ii) $1.84, (iii) $2.57, (iv) $1.39, (v) $1.69 and (vi) $1.80, respectively, per share of
Common Stock.

               (b)     Automatic Conversion.   
Subject to the proviso hereto, each share of Series A Preferred Stock, Series A-1 Preferred
Stock, Series B Preferred Stock, Series C-1 Preferred Stock, Series C-2 Preferred Stock, Series C-3 Preferred Stock, Series D
Preferred Stock, Series E Preferred Stock and Series F-1 Preferred Stock shall automatically be converted into shares of Common Stock
at the then-effective Conversion Price upon the closing of the sale of the Corporation's Common Stock in a firm commitment,
underwritten public offering registered under the Securities Act of 1933, as amended (the "Securities Act"), other than a
registration relating solely to a transaction under Rule 145 under the Securities Act (or any successor thereto) or to an employee
benefit plan of the Corporation, at a public offering price (prior to underwriters' discounts and expenses) equal to or exceeding
$1.00 per share of Common Stock (as adjusted for any stock dividends, combinations or splits with respect to the Common Stock), in
which the aggregate proceeds to the Corporation and/or any selling stockholders (prior to underwriters' discounts and expenses) are
at least $50,000,000; provided, that if such public offering price in such offering shall be less than $3.00 per share, the number of
shares of Common Stock to be issued on such conversion of shares of Series D Preferred Stock under this paragraph (b) pursuant to the
then in effect Conversion Price shall be increased by multiplying such number by a fraction, the numerator of which shall be $3.00
and the denominator of which shall be such public offering price per share.

               (c)     Mechanics of Conversion.

                         (I)     
Before any holder of Series A Preferred Stock, Series A-1 Preferred Stock, Series B Preferred Stock, Series
C-1 Preferred Stock, Series C-2 Preferred Stock, Series C-3 Preferred Stock, Series D Preferred Stock, Series E Preferred Stock or
Series F-1 Preferred Stock shall be entitled to convert the any of such shares into shares of Common Stock pursuant to paragraph (a) of
this Section C.1(iv), such holder shall surrender the certificate or certificates

7

evidencing such shares, duly endorsed, at the office of the Corporation or of any transfer agent for such stock, and shall give written notice to the Corporation at such office of
the number of shares that such holder elects to so convert and shall state therein the name or names in which such holder wishes the
certificate or certificates for such shares of Common Stock to be issued.  The Corporation shall, as soon as practicable thereafter
(but in any event within 20 business days thereafter), issue and deliver to such holder of Series A Preferred Stock, Series A-1
Preferred Stock, Series B Preferred Stock, Series C-1 Preferred Stock, Series C-2 Preferred Stock, Series C-3 Preferred Stock, Series
D Preferred Stock, Series E Preferred Stock or Series F-1 Preferred Stock, as the case may be, a certificate or certificates for the
number of shares of Common Stock to which such holder shall be entitled as aforesaid and, if applicable, a certificate or
certificates representing any such shares of any such Preferred Stock that are not being so converted (but were otherwise represented
by a certificate that included shares that were being so converted).  Any such conversion shall be deemed to have been made
immediately prior to the close of business on the date of surrender of the certificate or certificates for the shares of Series A
Preferred Stock, Series A-1 Preferred Stock, Series B Preferred Stock, Series C-1 Preferred Stock, Series C-2 Preferred Stock, Series
C-3 Preferred Stock, Series D Preferred Stock, Series E Preferred Stock or Series F-1 Preferred Stock, as the case may be, 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 on such date.

                         (II)     
In the event of an automatic conversion pursuant to paragraph (b) of this Section C.1(iv), the conversion
may, at the option of any holder tendering shares of Series A Preferred Stock, Series A-1 Preferred Stock, Series B Preferred Stock,
Series C-1 Preferred Stock, Series C-2 Preferred Stock, Series C-3 Preferred Stock, Series D Preferred Stock, any series of Series E
Preferred Stock or Series F-1 Preferred Stock for conversion, be conditioned upon the closing with the underwriters of the sale of
securities pursuant to such offering, in which event the person(s) entitled to receive the Common Stock upon conversion of the Series
A Preferred Stock, Series A-1 Preferred Stock, Series B Preferred Stock, Series C-1 Preferred Stock, Series C-2 Preferred Stock,
Series C-3 Preferred Stock, Series D Preferred Stock, any series of Series E Preferred Stock or Series F-1 Preferred Stock shall not be
deemed to have converted such series of Preferred Stock until immediately prior to the closing of such sale of securities.  No holder
of shares of Series A Preferred Stock, Series A-1 Preferred Stock, Series B Preferred Stock, Series C-1 Preferred Stock, Series C-2
Preferred Stock, Series C-3 Preferred Stock, Series D Preferred Stock, any series of Series E Preferred Stock or Series F-1 Preferred
Stock shall receive certificates for shares of Common Stock upon such conversion unless and until such holder shall surrender the
certificate or certificates therefor, duly endorsed, at the office of the Corporation or of any transfer agent for such stock and
shall give written direction to the Corporation of the name or names in which such holder wishes the certificate or certificates for
such shares of Common Stock to be issued.  Until surrendered as provided above, each certificate previously representing shares of
Preferred Stock shall be deemed for all corporate purposes to represent the number of shares of Common Stock resulting from such
automatic conversion.

for which adjustment of the Conversion Price is made pursuant to paragraph (e) or
paragraph (f) of this Section C.1(iv).

                         
(II)      No Adjustment of Conversion Price.  Any provision of this Certificate of Incorporation to the contrary
notwithstanding, no adjustment in any Conversion Price shall be made in respect of the issuance of Additional Shares of Common Stock
unless the consideration per share (determined pursuant to subparagraph (d)(V) of this Section C.1(iv)) for an Additional Share of
Common Stock issued or deemed to be issued by the Corporation is less than such applicable Conversion Price in effect on the date of,
and immediately prior to, such issue.

                         
(III)     Deemed Issue of Additional Shares of Common Stock.  In the event 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 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
for Convertible Securities, 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:

               
                  
(1)     no further adjustments in the applicable Conversion Price shall be made upon the subsequent issue
of such Convertible
Securities where an adjustment to the Conversion Price had been made on the
record date, or shares of Common Stock upon the exercise of such Options or
conversion or exchange of such Convertible Securities, in each case where an
adjustment to the Conversion Price had been made on the record date or issue
date;

10

               
                  
(2)     if such Options or Convertible Securities by their terms provide, with the passage of time or
otherwise, for any increase
or decrease in the consideration payable to the Corporation, or decrease or
increase in the number of shares of Common Stock issuable, 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 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 applicable Conversion Price shall affect Common Stock
previously issued upon conversion of the Series A Preferred Stock, Series A-1
Preferred Stock, Series B Preferred Stock, Series C-1 Preferred Stock, Series
C-2 Preferred Stock, Series C-3 Preferred Stock, Series D Preferred Stock, any
series of Series E Preferred Stock or Series F-1 Preferred Stock);

               
                  
(3)     upon the expiration of any such Options or any rights of conversion or exchange under such
Convertible Securities
which shall not have been exercised, the applicable Conversion Price computed
upon the original issuance 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:

               
                
            (A)     
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

               
                
            (B)     
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 exercised,
plus the consideration deemed to have been received by the Corporation
(determined pursuant to subparagraph (d)(V) of this Section C.1(iv)) upon the
issue of the Convertible Securities with respect to which such Options were
actually exercised;

               
                  
(4)     no readjustment pursuant to clause (2) or (3) above shall have the effect of increasing the
applicable Conversion Price
to an amount which exceeds the lower of (a) the applicable Conversion Price
on the original adjustment date, or (b) the applicable Conversion Price
that would have resulted from any issuance of Additional Shares of Common Stock,
other than those Additional Shares of Common Stock causing such readjustment,
between the original adjustment date and such readjustment date;

11

               
                  
(5)     in the case of any Options which expire by their terms not more than 30 days after the date of
issue thereof, no
adjustment of the applicable Conversion Price shall be made until the expiration
or exercise of all such Options, whereupon such adjustment shall be made in the
same manner provided in clause (3) above; and

               
                  
(6)     in the event that any adjustment described in this subparagraph (d)(III) is made, with respect to
any Additional Shares of
Common Stock that were originally issued (or deemed issued) for a consideration
per share equal to or in excess of the applicable Conversion Price then in
effect that, had such adjustment been made prior to such original issue date (or
deemed original issue date) would have caused such Additional Shares of Common
Stock to be issued for a consideration per share less than the applicable
Conversion Price then in effect, then such Additional Shares of Common Stock
shall be deemed to have been issued as of the date of any such adjustment.

                         
(IV)     Adjustment of Conversion Price Upon Issuance of Additional Shares of Common Stock.  In the event this
Corporation, at any time after the Original Issue Date, shall issue Additional Shares of Common Stock (including Additional Shares of
Common Stock deemed to be issued pursuant to subparagraph (d)(III) of this Section C.1(iv)) 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, the applicable Conversion Price shall be reduced, concurrently with such issue, to a price (calculated to the
nearest cent):

               
                  
(1)     for Series D Preferred Stock, equal to the lowest consideration per share received or to be received by the
Corporation in such issuance of Additional Shares of Common Stock; and

               
                  
(2)     for Series A Preferred Stock, Series A-1 Preferred Stock, Series B Preferred Stock, Series C-1 Preferred
Stock, Series C-2 Preferred Stock, Series C-3 Preferred Stock, each series of Series E Preferred Stock and Series F-1 Preferred Stock,
determined by multiplying the applicable Conversion Price by a fraction, the numerator of which shall be the number of shares of
Common Stock outstanding immediately prior to such issue plus the number of shares of Common Stock which the aggregate consideration
received by the Corporation for the total number of Additional Shares of Common Stock so issued would purchase at the applicable
Conversion Price in effect immediately prior to such issuance, and 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.  For the
purpose of the above calculation, the number of shares of Common Stock outstanding immediately prior to such issue shall be
calculated on a fully diluted basis, as if all outstanding shares of Series A Preferred Stock, Series A-1 Preferred Stock, Series B
Preferred Stock, Series C-1 Preferred Stock, Series C-2 Preferred Stock, Series C-3 Preferred Stock, Series D Preferred Stock, Series
E Preferred Stock and Series F-1 Preferred Stock and all Convertible Securities had been fully converted into shares of Common Stock
immediately prior to such issuance and all outstanding Options had been fully exercised immediately prior to such issuance (and the
resulting securities fully converted into shares of Common Stock, if so convertible) as of such date, but not including in such
calculation any additional shares of Common Stock issuable with respect to outstanding shares of Series A Preferred Stock, Series A-1
Preferred Stock, Series B Preferred Stock, Series C-1 Preferred Stock, Series C-2 Preferred Stock, Series C-3 Preferred Stock, Series
D Preferred Stock, Series E Preferred Stock and Series F-1 Preferred Stock, Convertible Securities or Options solely as a result of the
adjustment of the respective Conversion Prices (or other conversion ratios) resulting from the issuance of the Additional Shares of
Common Stock causing the adjustment in question.

12

                         
(V)     Determination of Consideration.  For purposes of paragraph (d) of this Section C.1(iv), the consideration
received by the Corporation for the issue of any Additional Shares of Common Stock shall be computed as follows:

               
                  
(1)     Cash and Property.  Such consideration shall:

               
                
            (A)     
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;

               
                
            (B)     
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

               
                
            (C)     
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 (A) and (B)
above, as determined in good faith by the Board of Directors.

               
                  
(2)     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 subparagraph (d)(III) of this
Section C.1(iv), relating to Options and Convertible Securities shall be
determined by dividing:

               
                
            (A)     
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 Options for Convertible Securities
and the conversion or exchange of such Convertible Securities by

               
                
            (B)     
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 conversion or exchange of such Convertible
Securities

               (e)     Adjustments
 to Conversion Prices for Stock Dividends and for Combinations or Subdivisions of Common Stock.  In the
event that the Corporation at any time or from time to time after the Original Issue Date shall declare or pay, without
consideration, any dividend on the Common Stock payable in shares of Common Stock or in any right to acquire shares of Common Stock
for no consideration, 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 than by payment of a dividend in shares of Common Stock or in any right
to acquire shares of Common Stock), 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 the applicable Conversion Price in effect
immediately prior to such event shall, concurrently with

13

the effectiveness of such event, be proportionately decreased or increased,
as appropriate.  In the event that the Corporation shall declare or pay, without consideration, any dividend on the Common Stock
payable in any right to acquire shares of Common Stock for no consideration, then the Corporation shall be deemed to have made a
dividend payable in shares of Common Stock in an amount equal to the maximum number of shares issuable upon exercise of such rights
to acquire Common Stock.

               (f)     
Adjustments for Reclassification and Reorganization.  If the Common Stock issuable upon conversion of the Series A
Preferred Stock, Series A-1 Preferred Stock, Series B Preferred Stock, Series C-1 Preferred Stock, Series C-2 Preferred Stock, Series
C-3 Preferred Stock, Series D Preferred Stock, any series of Series E Preferred Stock or Series F-1 Preferred Stock shall be changed
into the same or a different number of shares of any other class or classes of stock, whether by capital reorganization,
reclassification or otherwise (other than a subdivision or combination of shares provided for in paragraph (e) of this Section
C.1(iv) above or a merger or other reorganization referred to in paragraph (c) of Section C.1(iii) above), the applicable Conversion
Price then in effect shall, concurrently with the effectiveness of such reorganization or reclassification, be proportionately
adjusted so that the Series A Preferred Stock, the Series A-1 Preferred Stock, the Series B Preferred Stock, the Series C-1 Preferred
Stock, the Series C-2 Preferred Stock, the Series C-3 Preferred Stock, the Series D Preferred Stock, each series of Series E
Preferred Stock and the Series F-1 Preferred Stock shall thereafter be convertible into, in lieu of the number of shares of Common
Stock which the holders would otherwise have been entitled to receive, a number of shares of such other class or classes of stock
equivalent to the number of shares of Common Stock that would have been received by the holders upon conversion of the Series A
Preferred Stock, the Series A-1 Preferred Stock, the Series B Preferred Stock, the Series C-1 Preferred Stock, the Series C-2
Preferred Stock, the Series C-3 Preferred Stock, the Series D Preferred Stock, each such series of Series E Preferred Stock or the
Series F-1 Preferred Stock immediately before that change.

               (g)     
No Impairment.  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 of 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 C.1(iv) and in the taking of all
such action as may be necessary or appropriate in order to protect the Conversion Price against impairment.

               (h)

series of Series E Preferred Stock or Series F-1 Preferred Stock, as the case may be.

               (i)

outstanding shares of the Series A Preferred Stock, Series A-1 Preferred Stock, Series B Preferred Stock, Series C-1 Preferred Stock,
Series C-2 Preferred Stock, Series C-3 Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F-1 Preferred
Stock:  (I) to declare any dividend or distribution upon its Common Stock, whether in cash, property, stock or other securities,

C-3 Preferred Stock, Series D Preferred Stock, any series of Series E Preferred Stock and Series F-1 Preferred Stock:

               
                  
(1)     at least twenty (20) days' prior written notice of the date on which a record shall be taken for such
dividend, distribution or subscription rights (and specifying the date on which the holders of Common Stock shall be entitled
thereto) or for determining rights to vote, if any, in respect of the matters referred to in clauses (III) and (IV) above; and

written notice of the date when the same shall take place (and specifying the date on which the holders of Common Stock shall be
entitled to exchange their Common Stock for securities or other property deliverable upon the occurrence of such event).

               (j)     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 Common Stock on conversion of Series A Preferred Stock, Series A-1 Preferred Stock, Series B Preferred
Stock, Series C-1 Preferred Stock, Series C-2 Preferred Stock, Series C-3 Preferred Stock, Series D Preferred Stock, any series of
Series E Preferred Stock or Series F-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.

               (k)     
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 A-1 Preferred Stock, Series B Preferred Stock, Series C-1 Preferred Stock, Series C-2 Preferred Stock, Series
C-3 Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F-1 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 each such series of Preferred Stock; and if at any time the number of authorized but unissued shares of Common Stock shall not be sufficient to effect
the conversion

15

of all then outstanding shares of each such series of Preferred Stock, the Corporation will take such corporate action
as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such number of
shares as shall be sufficient for such purpose, including, without limitation, engaging in best efforts to obtain the requisite
stockholder approval of any necessary amendment to this Certificate of Incorporation.

               (l)

Stock, Series B Preferred Stock, Series C-1 Preferred Stock, Series C-2 Preferred Stock, Series C-3 Preferred Stock, Series D
Preferred Stock, Series E Preferred Stock or Series F-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 the aforementioned aggregation,
the conversion would result in the issuance of a fraction of a share of 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).

               (m)

Stock, Series B Preferred Stock, Series C-1 Preferred Stock, Series C-2

Other Series of Preferred Stock.  The terms of the shares of each other series of Preferred Stock shall be as stated
and expressed in this Certificate of Incorporation or any amendment hereto, or in the resolution or resolutions providing for the
issuance of such series of Preferred Stock adopted by the Board of Directors.  Subject to the requirements of the GCL and the
provisions of this Certificate of Incorporation, the Board of Directors is expressly authorized to cause any number of the authorized
and undesignated shares of Preferred Stock to be issued from time to time in one or more series of Preferred Stock with such voting
powers, full or limited, or no voting powers, and such designations, preferences and relative, participating, optional or other
special rights, and qualifications, limitations or restrictions thereof, if any, as the Board of Directors may fix by resolution or
resolutions, prior to the issuance of any shares of such series of Preferred Stock, each of which series may differ from any and all
other series, including, without limiting the generality of the foregoing, the following:

               (i)     
The number of shares constituting such series of Preferred Stock and the designation thereof;

               (ii)     The dividend rate, if any, on the shares of such series of Preferred Stock, whether and the extent to which any such
dividends shall be cumulative or non-cumulative, the relative rights of priority, if any, of payments of any dividends, and the times
at which, and the terms and conditions on which, any dividends shall be paid;

               (iii)     The right, if any, of the holders of shares of such series of Preferred Stock to vote and the manner of voting,
except as may otherwise be provided by the GCL;

               (iv)     The right, if any, of the holders of shares of such series of Preferred Stock to convert the same into, or the
right, if any, of the Corporation to exchange the same for, another class or series of stock of the Corporation and the terms and
conditions, including any provision for future adjustment in the conversion or exchange rate, under which said shares may be
converted or exchanged;

18

               (v)     The redemption or purchase price or prices of the shares of such series of Preferred Stock, if any, and the times at
which, and the terms and conditions on which, the shares of such series of Preferred Stock may be redeemed or purchased;

               (vi)     The terms of the sinking fund, if any, to be provided for such series of Preferred Stock, and the terms and amount
of such sinking fund;

               (vii)     The rights of the holders of shares of such series of Preferred Stock in the event of a voluntary or involuntary
liquidation, dissolution or winding up of the Corporation and the relative rights of priority, if any, of such holders with respect

               (viii)     Any other relative powers, preferences and rights, and any qualifications, limitations or restrictions, of such
series of Preferred Stock.

D.        Terms of Common Stock.

           The voting powers and relative, participating, optional and other special rights of the Common Stock, and the
qualifications, limitations and restrictions thereof, are as follows:

             1.     Voting Rights and Powers.  Except as provided in the GCL, the holders of shares of the Common Stock shall
vote together as a single class (with the holders of all series of Preferred Stock entitled to vote together with the holders of the
shares of Common Stock) on all matters as to which such holders are entitled to vote.

             2.     Dividend Rights.   No cash dividends may be declared and paid upon the Common Stock so long as any Series A
Preferred Stock, Series A-1 Preferred Stock, Series B Preferred Stock, Series C-1 Preferred Stock, Series C-2 Preferred Stock, Series
C-3 Preferred Stock, Series D Preferred Stock, Series E Preferred Stock, Series F-1-1 Preferred Stock or other securities ranking prior
to the Common Stock upon dissolution, liquidation or winding up of the Corporation is outstanding.  Thereafter, cash dividends may be
declared and paid upon the Common Stock in such amounts and at such times as the Board of Directors may determine.  Funds otherwise
legally available for the payment of dividends on the Common Stock shall not be restricted or reduced by reason of there being any
excess of the aggregate preferential amount of any series of Preferred Stock outstanding over the aggregate par value thereof.

             3.     Liquidation Rights.  In the event of any liquidation, dissolution or winding up of the Corporation, whether
voluntary or involuntary, after there shall have been paid or set apart for payment of holders of any outstanding shares of Preferred
Stock the full preferential amounts to which they are entitled under Section C.1(iii) or otherwise, the entire remaining assets and
funds of the Corporation legally available for distribution, if any, to its shareholders shall be distributed ratably among the
holders of the Common Stock in proportion to the shares of Common Stock then held by them.

          3.     The amendment of the Certificate
of Incorporation herein certified has been duly adopted and written consent has
been given in accordance with the provisions of Sections 228 and 242 of the
General Corporation Law of the State of Delaware.
