EXHIBIT 3.1

              CERTIFICATE OF DESIGNATIONS, PREFERENCES, AND RIGHTS
                           OF SERIES A PREFERRED STOCK
                                       OF
                           INTERLEUKIN GENETICS, INC.
                         (Pursuant to Section 151 of the
                        Delaware General Corporation Law)

      Interleukin Genetics, Inc., a Delaware corporation (the "Corporation"),
hereby certifies that the following resolution was duly approved and adopted by
the Board of Directors of the Corporation (the "Board of Directors") at a
meeting duly held on March 4, 2003, which resolution remains in full force and
effect on the date hereof:

      RESOLVED, that pursuant to the authority expressly granted to and vested
in the Board of Directors by the provisions of the Certificate Of Incorporation
of the Corporation (the "Certificate of Incorporation") and its By-Laws (the
"Bylaws"), and in accordance with Section 151 of the General Corporation Law of
the State of Delaware (the "DGCL"), there is hereby created, out of the FIVE
MILLION (5,000,000) shares of Preferred Stock, par value $0.001 per share (the
"Preferred Stock"), of the Corporation authorized, unissued and undesignated, a
series of the Preferred Stock consisting of FIVE MILLION (5,000,000) shares,
which series shall have the following powers, designations, preferences and
relative, participating, optional or other rights, and the following
qualifications, limitations and restrictions (in addition to any powers,
designations, preferences and relative, participating, optional or other rights,
and any qualifications, limitations and restrictions, set forth in the
Certificate of Incorporation which are applicable to the Preferred Stock):

The powers, preferences, rights, restrictions, and other matters relating to the
Series A Preferred Stock are as follows:

1.    DIVIDENDS.

      1.1 RATE. The holders of the Series A Preferred Stock shall be entitled to
receive dividends at the rate of 8% of the Original Purchase Price (as defined
below) per annum, payable out of funds legally available therefore. Such
dividends shall be payable only when, as and if declared by the Board of
Directors and shall be non-cumulative.

            No dividends (other than those payable solely in the Common Stock of
the Company) shall be paid on any Common Stock of the Company during any fiscal
year of the Company until dividends at the rate of 8% of the Original Purchase
Price accruing on a daily basis based on a 365-day year (and for purposes of
this Section 1.1, the adjustment provided for in the second paragraph of Section
2.1 shall be effective only as of the date of the additional capital
contribution referred to in that paragraph) on the Series A Preferred Stock,
shall have been paid or declared and set apart during that fiscal year, and no
dividends shall be paid on any share of Common Stock unless a dividend
(including the amount of any dividends paid pursuant to the above provisions of
this Section) is paid with respect to all outstanding shares of Series A
Preferred Stock in an amount for each such share of Series A Preferred Stock
equal to or greater than the aggregate amount of such dividends for all shares
of Common Stock into which each such share of Series A Preferred Stock could
then be converted.

      1.2 STOCK DIVIDEND. If the Company shall declare a distribution (other
than any distribution described in Section 2) payable in securities of other
persons, evidences of indebtedness issued by the Company or other persons,
assets (excluding cash dividends) or options or rights to purchase any such

securities or evidences of indebtedness, then, in each such case the holders of
the Series A Preferred Stock shall be entitled to a proportionate share of any
such distribution as though the holders of the Series A Preferred Stock were the
holders of the number of shares of Common Stock of the Company into which their
respective shares of Series A Preferred Stock are convertible as of the record
date fixed for the determination of the holders of Common Stock of the Company
entitled to receive such distribution.

2.    LIQUIDATION PREFERENCE.

      2.1 FIRST. In the event of any liquidation, dissolution or winding up of
the Company, whether voluntary or involuntary, the holders of the Series A
Preferred Stock shall be entitled to receive, prior and in preference to any
distribution of any of the assets or surplus funds of the Company to the holders
of the Common Stock by reason of their ownership thereof, the amount of two
times the Original Purchase Price plus all declared but unpaid dividends on such
share for each share of Series A Preferred Stock then held by them. Except as
provided below, the "Original Purchase Price" shall be $1.40 per share (as
adjusted for any stock dividends, combinations or splits with respect to such
shares). If upon the occurrence of any liquidation, dissolution or winding up of
the Company, the assets and funds thus distributed among the holders of the
Series A Preferred Stock shall be insufficient to permit the payment to such
holders of the full aforesaid preferential amount, then the entire assets and
funds of the Company legally available for distribution shall be distributed
ratably among the holders of the Series A Preferred Stock in proportion to the
preferential amount each such holder is otherwise entitled to receive.

      Notwithstanding the above, upon the additional capital contribution made
upon the achievement of the Milestone, as provided in Article 2 of the Stock
Purchase Agreement, dated as of March 5, 2003, between the Company and Pyxis
Innovations Inc., a Delaware corporation (the "STOCK PURCHASE Agreement"), the
Original Purchase Price shall be deemed to be $1.80 per share, from and after
the date of such additional capital contribution.

      2.2 SECOND. After payment to the holders of the Series A Preferred Stock
of the amounts set forth in Section 2.1, the entire remaining assets and funds
of the Company legally available for distribution, if any, shall be distributed
among the holders of the Common Stock and the Series A Preferred Stock in
proportion to the shares of Common Stock then held by them and the shares of
Common Stock which they then have the right to acquire upon conversion of the
shares of Series A Preferred Stock then held by them.

      2.3 CHANGE OF CONTROL. At the election of the holders of at least a
majority of the outstanding shares of Series A Preferred Stock, for purposes of
this Section 2, (i) any acquisition of the Company by means of merger or other
form of corporate reorganization in which outstanding shares of the Company are
exchanged for securities or other consideration issued, or caused to be issued,
by the acquiring corporation or its subsidiary (other than a mere
reincorporation transaction) or (ii) a sale of all or substantially all of the
assets of the Company, shall be treated as a liquidation, dissolution or winding
up of the Company and shall entitle the holders of Series A Preferred Stock and
Common Stock to receive at the closing in cash, securities or other property
(valued as provided in Section 2.4) amounts as specified in Sections 2.1 and
2.2.

      2.4 VALUATION. Whenever the distribution provided for in this Section 2
shall be payable in securities or property other than cash, the value of such
distribution shall be the fair market value of such securities or other property
as determined by an investment banking firm of national recognition, which firm
shall be selected by unanimous resolution of the Board of Directors.

3.    VOTING RIGHTS; DIRECTORS.


                                      -2-

      3.1 AS-CONVERTED BASIS. Each holder of shares of the Series A Preferred
Stock shall be entitled to the number of votes equal to the number of shares of
Common Stock into which such shares of Series A Preferred Stock could be
converted and shall have voting rights and powers equal to the voting rights and
powers of the Common Stock (except as otherwise expressly provided herein or as
required by law, voting together with the Common Stock as a single class) and
shall be entitled to notice of any stockholders' meeting in accordance with the
Bylaws of the Company. Fractional votes shall not, however, be permitted and any
fractional voting rights resulting from the above formula (after aggregating all
shares into which shares of Series A Preferred Stock held by each holder could
be converted) shall be rounded to the nearest whole number (with one-half being
rounded upward). Each holder of Common Stock shall be entitled to one vote for
each share of Common Stock held.

      3.2 ELECTION OF DIRECTORS. So long as at least forty percent (40%) of the
originally issued shares of Series A Preferred Stock remain outstanding, (i) the
Board of Directors shall consist of five members, (ii) the holders of Series A
Preferred Stock, voting together as a class, shall be entitled to nominate and
elect four members of the Board of Directors at each meeting or pursuant to each
consent, if permitted, of the Company's stockholders for the election of
directors and (iii) the holders of the Common Stock, as a class, shall be
entitled to elect one member of the Board of Directors at each meeting or
pursuant to each consent, if permitted, of the Company's stockholders for the
election of directors. A director elected by the holders of Common Stock shall
be nominated by the holders of the Common Stock or by another director, if any,
elected by the holders of the Common Stock.

      3.3 VACANCY; REMOVAL. In the case of any vacancy in the office of a
director occurring among the directors elected by the holders of the Series A
Preferred Stock or Common Stock pursuant to Section 3.2, the remaining director
or directors so elected by the holders of the Series A Preferred Stock or Common
Stock, as the case may be, may, by affirmative vote of a majority thereof (or
the remaining director so elected if there is but one, or if there is no such
director remaining, by the affirmative vote of the holders of a majority of the
shares of that class) elect a successor or successors to hold the office for the
unexpired term of the director or directors whose place or places shall be
vacant. Any director who shall have been elected by the holders of the Series A
Preferred Stock or Common Stock or any director so elected as provided in the
preceding sentence hereof, may be removed during the aforesaid term of office,
whether with or without cause, only by the affirmative vote of the holders of a
majority of the Series A Preferred Stock or Common Stock, as the case may be.

4.    CONVERSION.

      The holders of the Series A Preferred Stock shall have conversion rights
as follows (the "CONVERSION RIGHTS"):

      4.1 RIGHT TO CONVERT. At any time, to the extent that the Corporation has
sufficient shares of Common Stock authorized and not otherwise reserved, each
share of Series A Preferred Stock shall be convertible, at the option of the
holder thereof, at any time after the date of issuance of such share at the
office of the Company or any transfer agent for such stock, into such number of
fully paid and nonassessable shares of Common Stock as is determined by dividing
the Original Purchase Price by the Series A Conversion Price applicable to such
share, determined as hereinafter provided, in effect on the date the certificate
is surrendered for conversion.

            4.1.1 NO MILESTONE. The price at which shares of Common Stock shall
be deliverable upon conversion of shares of the Series A Preferred Stock (the
"SERIES A CONVERSION PRICE") shall be $0.2486 per share of Common Stock, subject
to adjustment as provided in Sections 4.1.2 and 4.1.3.


                                      -3-

            4.1.2 MILESTONE. Upon the additional capital contribution made upon
the achievement of the Milestone, as provided in Article 2 of the Stock Purchase
Agreement, the Series A Conversion Price shall be adjusted as of the date of
such additional capital contribution to the Series A Conversion Price that would
be in effect on such date if the Series A Conversion Price had originally been
$0.3196 per share of Common Stock and such Series A Conversion Price had been
adjusted through such date as provided herein.

            4.1.3 AUTOMATIC CONVERSION PRICE ADJUSTMENT.  The Series A
Conversion Price shall also be adjusted as hereinafter provided.

      4.2   MECHANICS OF CONVERSION.

            4.2.1 EXCHANGE OF CERTIFICATES. Before any holder of Series A
Preferred Stock shall be entitled to convert the same into shares of Common
Stock, he shall surrender the certificate or certificates therefore, duly
endorsed, at the office of the Company or of any transfer agent for such stock,
and shall give written notice to the Company at such office that he elects to
convert the same and shall state therein the name or names in which he wishes
the certificate or certificates for shares of Common Stock to be issued. The
Company shall, as soon as practicable thereafter, issue and deliver at such
office to such holder of Series A Preferred Stock, a certificate or certificates
for the number of shares of Common Stock to which he shall be entitled as
aforesaid. Such conversion shall be deemed to have been made immediately prior
to the close of business on the date of surrender of the shares of Series A
Preferred Stock 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.

            4.2.2 CONDITIONAL EXCHANGE. If the conversion is in connection with
an underwritten offering of securities pursuant to the Securities Act of 1933,
as amended (the "Act"), the conversion may, at the option of any holder
tendering shares of Series A 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 shall not be deemed to have converted
such Series A Preferred Stock until immediately prior to the closing of such
sale of securities.

      4.3 SERIES A CONVERSION PRICE ADJUSTMENTS FOR CERTAIN DILUTIVE ISSUANCES.
The Series A Conversion Price of Series A Preferred Stock shall be subject to
adjustment from time to time as follows:

            4.3.1 DILUTIVE ISSUANCE. If the Company shall issue, after the date
upon which any shares of Series A Preferred Stock were first issued (the "SERIES
A PURCHASE DATE"), any Additional Stock (as defined below) without consideration
or for a consideration per share less than the Series A Series A Conversion
Price for such series in effect immediately prior to the issuance of such
Additional Stock, the Series A Conversion Price for such series in effect
immediately prior to each such issuance shall forthwith (except as otherwise
provided in Section 4.3) be adjusted to a price determined by multiplying such
Series A Conversion Price by a fraction, the numerator of which shall be the
number of shares of Common Stock outstanding immediately prior to such issuance
(including shares of Common Stock deemed to be issued pursuant to subsection
4.3.5(A) or (B)) plus the number of shares of Common Stock that the aggregate
consideration received by the Company for such issuance would purchase at such
Series A Conversion Price; and the denominator of which shall be the number of
shares of Common Stock outstanding immediately prior to such issuance (including
shares of Common Stock deemed to be issued pursuant to subsection 4.3.5(A) or
(B)) plus the number of shares of such Additional Stock.


                                      -4-

            4.3.2 NO ADJUSTMENT. No adjustment of the Series A Conversion Price
for the Series A Preferred Stock shall be made in an amount less than $0.01 per
share, provided that any adjustments that are not required to be made by reason
of this sentence shall be carried forward and shall be either taken into account
in any subsequent adjustment made prior to three years from the date of the
event giving rise to the adjustment being carried forward, or shall be made at
the end of three years from the date of the event giving rise to the adjustment
being carried forward. Except to the limited extent provided for in 4.3.5(C) and
(D), no adjustment of such Series A Conversion Price pursuant to this Section
4.3 shall have the effect of increasing the Series A Conversion Price above the
Series A Conversion Price in effect immediately prior to such adjustment.

            4.3.3 CASH PAYMENT. In the case of the issuance of Common Stock for
cash, the consideration shall be deemed to be the amount of cash paid therefor
before deducting any reasonable discounts, commissions or other expenses
allowed, paid or incurred by the Company for any underwriting or otherwise in
connection with the issuance and sale thereof.

            4.3.4 NON-CASH PAYMENT. In the case of the issuance of the Common
Stock for a consideration in whole or in part other than cash, the consideration
other than cash shall be deemed to be the fair value thereof as determined by
the Board of Directors irrespective of any accounting treatment.

            4.3.5 DERIVATIVE SECURITIES. In the case of the issuance of options
to purchase or rights to subscribe for Common Stock, securities by their terms
convertible into or exchangeable for Common Stock or options to purchase or
rights to subscribe for such convertible or exchangeable securities, the
following provisions shall apply:

                  (A) The aggregate maximum number of shares of Common Stock
deliverable upon exercise (assuming the satisfaction of any conditions to
exercisability, including without limitation, the passage of time, but without
taking into account potential antidilution adjustments) of such options to
purchase or rights to subscribe for Common Stock shall be deemed to have been
issued at the time such options or rights were issued and for a consideration
equal to the consideration (determined in the manner provided in Section 4.3.3
and 4.3.4), if any, received by the Company upon the issuance of such options or
rights plus the minimum exercise price provided in such options or rights
(without taking into account potential antidilution adjustments) for the Common
Stock covered thereby.

                  (B) The aggregate maximum number of shares of Common Stock
deliverable upon conversion of, or in exchange (assuming the satisfaction of any
conditions to convertibility or exchangeability, including, without limitation,
the passage of time, but without taking into account potential antidilution
adjustments) for, any such convertible or exchangeable securities or upon the
exercise of options to purchase or rights to subscribe for such convertible or
exchangeable securities and subsequent conversion or exchange thereof shall be
deemed to have been issued at the time such securities were issued or such
options or rights were issued and for a consideration equal to the
consideration, if any, received by the Company for any such securities and
related options or rights (excluding any cash received on account of accrued
interest or accrued dividends), plus the minimum additional consideration, if
any, to be received by the Company (without taking into account potential
antidilution adjustments) upon the conversion or exchange of such securities or
the exercise of any related options or rights (the consideration in each case to
be determined in the manner provided in Sections 4.3.3 and 4.3.4).

                  (C) In the event of any change in the number of shares of
Common Stock deliverable or in the consideration payable to the Company upon
exercise of such options or rights or upon conversion of or in exchange for such
convertible or exchangeable securities, including, but not limited to, a change
resulting from the antidilution provisions thereof (unless such options or
rights or


                                      -5-

convertible or exchangeable securities were merely deemed to be included in the
numerator and denominator for purposes of determining the number of shares of
Common Stock outstanding for purposes of Section 4.3.1) the Series A Conversion
Price of the Series A Preferred Stock, to the extent in any way affected by or
computed using such options, rights or securities, shall be recomputed to
reflect such change, but no further adjustment shall be made for the actual
issuance of Common Stock or any payment of such consideration upon the exercise
of any such options or rights or the conversion or exchange of such securities.

                  (D) Upon the expiration of any such options or rights, the
termination of any such rights to convert or exchange or the expiration of any
options or rights related to such convertible or exchangeable securities, the
Series A Conversion Price of the Series A Preferred Stock, to the extent in any
way affected by or computed using such options, rights or securities or options
or rights related to such securities (unless such options or rights were merely
deemed to be included in the numerator and denominator for purposes of
determining the number of shares of Common Stock outstanding for purposes of
Section 4.3.1) shall be recomputed to reflect the issuance of only the number of
shares of Common Stock (and convertible or exchangeable securities that remain
in effect) actually issued upon the exercise of such options or rights, upon the
conversion or exchange of such securities or upon the exercise of the options or
rights related to such securities.

                  (E) The number of shares of Common Stock deemed issued and the
consideration deemed paid therefor pursuant to Sections 4.3.5(A) and (B) shall
be appropriately adjusted to reflect any change, termination or expiration of
the type described in either subsection 4.3.5(C) or (D).

            4.3.6 "ADDITIONAL STOCK" shall mean any shares of Common Stock
issued (or deemed to have been issued pursuant to Section 4.3.5) by the Company
after the Series A Purchase Date, other than:

                  (A)   Common Stock issued pursuant to a transaction
described in Section 4.4;

                  (B) Common Stock issuable or issued to employees, consultants
or directors of the Company directly or pursuant to a stock option plan or
restricted stock plan approved by the Board of Directors of the Company prior to
the Series A Purchase Date;

                  (C)   the issuance of Common Stock pursuant to the
conversion or exercise of convertible or exercisable securities;

                  (D) the issuance of securities pursuant to a bona fide, firmly
underwritten public offering of shares of Common Stock, registered under the
Act; or

                  (E) Common Stock issued (or deemed to have been issued)
pursuant to a transaction approved by a majority of the directors elected by the
holders of the Series A Preferred Stock.

      4.4 ADJUSTMENTS TO CONVERSION PRICES FOR STOCK DIVIDENDS AND FOR
COMBINATIONS OR SUBDIVISIONS OF COMMON STOCK. In the event that the Company at
any time or from time to time after the Series A Purchase Date shall declare or
pay, without consideration, any dividend on the Common Stock payable in Common
Stock or in any right to acquire 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 Common Stock or in any right to acquire 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 Series A Conversion Price shall, concurrently
with the effectiveness of such


                                      -6-

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

      4.5 ADJUSTMENTS FOR RECLASSIFICATION AND REORGANIZATION. If the Common
Stock issuable upon conversion of the Series A 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 Section 4.4 or a
merger or other reorganization referred to in Section 2.3) the Series A
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 shall 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 subject to receipt
by the holders upon conversion of the Series A Preferred Stock immediately
before that change.

      4.6 NO IMPAIRMENT. The Company 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 Company, 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 to protect the Conversion Rights of the holders of the Series A
Preferred Stock against impairment.

      4.7 CERTIFICATES AS TO ADJUSTMENTS. Upon the occurrence of each adjustment
or readjustment of any Conversion Price pursuant to this Section 4, the Company
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 a certificate executed by the Company's President or
Chief Financial Officer setting forth such adjustment or readjustment and
showing in detail the facts upon which such adjustment or readjustment is based.
The Company shall, upon the written request at any time of any holder of Series
A Preferred Stock, furnish or cause to be furnished to such holder a like
certificate setting forth (i) such adjustments and readjustments, (ii) the
Conversion Price for such series of Preferred Stock at the time in effect, and
(iii) the number of shares of Common Stock and the amount, if any, of other
property which at the time would be received upon the conversion of the Series A
Preferred Stock.

      4.8 NOTICES OF RECORD DATE. In the event that the Company shall propose at
any time: (i) to declare any dividend or distribution upon its Common Stock,
whether in cash, property, stock or other securities, whether or not a regular
cash dividend and whether or not out of earnings or earned surplus; (ii) to
offer for subscription pro rata to the holders of any class or series of its
stock any additional shares of stock of any class or series or other rights;
(iii) to effect any reclassification or recapitalization of its Common Stock
outstanding involving a change in the Common Stock; or (iv) to merge or
consolidate with or into any other corporation, or sell, lease or convey all or
substantially all of its assets, or to liquidate, dissolve or wind up; then, in
connection with each such event, the Company shall send to the holders of Series
A Preferred Stock:

            4.8.1 at least 10 days' prior written notice of the setting of a
date on which a record shall be taken for such dividend, distribution or
subscription rights (and specifying the date on which the


                                      -7-

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

            4.8.2 in the case of the matters referred to in clauses (iii) and
(iv) above, at least 10 days' prior written notice of the event.

      4.9 RESERVATION OF STOCK ISSUABLE UPON CONVERSION. Following the approval
at a meeting of the Company's stockholders and the subsequent filing of a
Certificate of Amendment of the Company's Certificate of Incorporation that
increases the authorized Common Stock of the Company in an amount sufficient to
permit the Board of Directors to reserve for issuance upon conversion of all the
Series A Preferred Stock the number of shares of Common Stock to which all of
such shares of Series A Preferred Stock are then convertible, the Company 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, 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 the Series A 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 the Series A
Preferred Stock, the Company will take such corporate action as may, in the
opinion of its counsel, be necessary from time to time to increase its
authorized but unissued shares of Common Stock to such number of shares as shall
be sufficient for the purpose of effecting the conversion of all of the
outstanding shares of the Series A Preferred Stock, including, without
limitation, engaging in best efforts to obtain the requisite stockholder
approval of any necessary amendment to this Certificate.

      4.10 FRACTIONAL SHARES. No fractional share shall be issued upon the
conversion of any share or shares of Series A Preferred Stock. All shares of
Common Stock (including fractions thereof) issuable upon conversion of more than
one share of Series A 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 Company 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).

      4.11 NOTICES. Any notice required by the provisions of this Section 4 to
be given to the holders of shares of Series A Preferred Stock shall be deemed
given if deposited in the United States mail, postage prepaid, or if sent by
facsimile or delivered personally by hand or nationally recognized courier and
addressed to each holder of record at such holder's address or facsimile number
appearing in the records of the Company.

5.    RESTRICTIONS AND LIMITATIONS.

      5.1 RESTRICTIONS. So long as any shares of Series A Preferred Stock remain
outstanding, the Company shall not, without the vote or written consent by the
holders of at least 75% of the then outstanding shares of the Series A Preferred
Stock:

            5.1.1 REDEMPTION OF PREFERRED. Redeem, purchase or otherwise acquire
for value (or pay into or set aside for a sinking fund for such purpose) any
share or shares of Series A Preferred Stock otherwise than by conversion in
accordance with Section 4.

            5.1.2 REDEMPTION OF COMMON. Redeem, purchase or otherwise acquire
(or pay into or set aside for a sinking fund for such purpose) any of the Common
Stock; provided, however, that this restriction shall not apply to the
repurchase of shares of Common Stock from employees, officers,


                                      -8-

directors, consultants or other persons performing services for the Company or
any subsidiary pursuant to agreements under which the Company has the option to
repurchase such shares at cost upon the occurrence of certain events, such as
