                     SERIES 2000 NON-VOTING PREFERRED STOCK

                                   AXCESS INC.

                         Pursuant to Section 151 of the
                             General Corporation Law
                            of the State of Delaware

         AXCESS INC., a corporation organized and existing under the General
Corporation Law of the State of Delaware (the "Company"), hereby certifies that,
pursuant to the authority contained in Article Fourth of its Certificate of
Incorporation, as amended, and in accordance with the provisions of Sections 103
and 151 of the General Corporation Law of the State of Delaware, its Board of
Directors has adopted the following resolution providing for the issuance of the
Series 2000 Non-Voting Preferred Stock:

         RESOLVED, that a series of the class of authorized preferred stock of
the Company is hereby created and the Board of Directors hereby fixes the
designation and amount thereof, and the voting powers, preferences and relative,
participating, optional and other special rights of the shares of such series,
and the qualifications, limitations or restrictions thereof as follows:

         SECTION 1.  DESIGNATION AND AMOUNT. The shares of such series shall
have a par value of $0.01 per share and shall be designated as Series 2000
Non-Voting Preferred Stock and the number of shares constituting the Series 2000
Non-Voting Preferred Stock shall be TWO THOUSAND FIVE HUNDRED (2,500). The
Series 2000 Non-Voting Preferred Stock shall have a stated value of Ten Thousand
Dollars ($10,000) per share (the "Original Issue Price").

         SECTION 2.  RANK. The Series 2000 Non-Voting Preferred Stock shall
rank: (a) junior to any other class or series of capital stock of the Company
hereafter created specifically ranking by its terms senior to the Series 2000
Non-Voting Preferred Stock (collectively the "Senior Securities"); (b) prior to
all of the Company's Common Stock and Non-Voting Common Stock, each $0.01 par
value per share (the "Common Stock"); (c) prior to any class or series of
capital stock of the Company hereafter created not specifically ranking by its
terms senior to or on parity with the Series 2000 Non-Voting Preferred Stock
(collectively, with the Common Stock, the "Junior Securities"); and (d) on a
parity with the Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock, Series I Preferred Stock, Series J Preferred Stock, Series 1999
Voting Preferred Stock, Series 1999 Non-Voting Preferred Stock of the Company,
and any class or series of capital stock of the Company hereafter created
specifically ranking by its terms on a parity with the Series 2000 Non-

<PAGE>   2

Voting Preferred Stock (the "Parity Securities"), in each case as to
distributions of assets upon liquidation, dissolution or winding up of the
Company, whether voluntary or involuntary (all such distributions being referred
to collectively as "Distributions").

         SECTION 3. DIVIDENDS AND DISTRIBUTIONS.

              (a) Subject to Section 3(d), the holders of record of shares of
Series 2000 Non-Voting Preferred Stock (the "Holders"), in preference to the
holders of shares of capital stock ranking junior to the Series 2000 Non-Voting
Preferred Stock as to dividends, shall be entitled to receive dividends on each
share of Series 2000 Non-Voting Preferred Stock held of record at the annual
rate of 8% of the Original Issue Price, payable semi-annually, to the extent of
funds legally available therefor. Such dividends shall be cumulative, shall
accrue on each share on a daily basis (calculated on the basis of a 360-day
year, whether or not earned or declared, from the date of original issue of such
shares) and shall be payable in arrears, when as and if declared by the Board of
Directors, on the last day of June and December in each year (each such date, a
"Dividend Payment Date"). Each such dividend will be paid to the Holders as they
appear on the stock register of the Company on the record date therefor as shall
be fixed by the Board of Directors, which record date shall not be more than 25
days or less than 10 days preceding the payment date thereof.

              (b) The Company may, at its option, make any dividend payment to
Holders of Series 2000 Non-Voting Preferred Stock in cash or in additional
shares (including fractional shares) of Series 2000 Non-Voting Preferred Stock
or in any combination of cash and such shares. Each such dividend payment (or
portion thereof) to be paid in shares of Series 2000 Non-Voting Preferred Stock
shall be paid by the issuance and delivery to such Holders of that number of
additional shares (including any fractional shares, if applicable) of Series
2000 Non-Voting Preferred Stock as shall be equal to the quotient obtained by
dividing the aggregate dollar amount of such dividend payment (or portion
thereof) by the Original Issue Price per share. Dividends to be paid in
additional shares of Series 2000 Non-Voting Preferred Stock shall be deemed to
have been made when certificates representing such additional shares of Series
2000 Non-Voting Preferred Stock have been delivered to the record holders of the
Series 2000 Non-Voting Preferred Stock entitled to receive the same, in
accordance with the instructions of such holders designated in writing to the
Company at least two business days prior to any Dividend Payment Date. All
shares of Series 2000 Non-Voting Preferred Stock paid as such dividends (the
"Dividend Shares") shall be validly issued, fully paid and non_assessable, shall
be free and clear of preemptive rights and liens, claims and encumbrances of any
kind. Subject to the other provisions of this Certificate of Designation,
holders of shares of Series 2000 Non-Voting Preferred Stock shall not be
entitled to any dividend, whether payable in cash, additional shares of Series
2000 Non-Voting Preferred Stock or other property, in excess of full cumulative
dividends as herein provided. No interest, or sum of money in lieu of interest,
shall be payable under this Certificate of Designation in respect of any
dividend payment or payments on the Series 2000 Non-Voting Preferred Stock which
may be in arrears.

              (c) So long as any Series 2000 Non-Voting Preferred Stock remains
outstanding, the Company will not redeem, purchase or otherwise acquire any
Junior Securities; nor will the Company declare or pay any dividend or make any
distribution (in each case, whether in cash or securities or assets in kind)
upon any Junior Securities (other than stock dividends on Junior Securities,
payable in shares of, options, warrants or similar rights to acquire shares of,
the same

                                       2

<PAGE>   3

class (and series, if applicable) of Junior Securities), or make any sinking
fund or other payment in respect of any of the foregoing if the Company shall
not have paid in full all accrued dividends on the Series 2000 Non-Voting
Preferred Stock in accordance with Section 3(a) hereof.

              (d) Anything contained herein to the contrary notwithstanding, if
at any time that any shares of Series 2000 Non-Voting Preferred Stock are
outstanding, the closing bid price per share of the Common Stock on the Nasdaq
Stock Market (or, if the Common Stock is not then included in Nasdaq, but is
listed on any national securities exchange, on the principal national securities
exchange on which the Common Stock is the listed) remains above $20.00 per share
(as adjusted for any stock splits, reverse stock splits, stock dividends or
similar events after the date of this Certificate of Designation) for twenty
(20) consecutive trading days, then, commencing on such 20th trading day, the
cumulative dividend will not be payable; provided, however, that, if the closing
bid price per share of the Common Stock remains thereafter below $20.00 for
twenty (20) consecutive trading days (as so adjusted), then the dividend will
resume as of such 20th day.

         SECTION 4.  LIQUIDATION PREFERENCE.

              (a) In the event of any liquidation, dissolution or winding up of
the Company (each a "Liquidation Preference"), either voluntary or involuntary,
the Holders of shares of Series 2000 Non-Voting Preferred Stock shall be
entitled to receive, immediately after any distributions to Senior Securities
required by the Company's Certificate of Incorporation or any certificate of
designation, and prior in preference to any distribution to Junior Securities,
and in parity with any distribution to Parity Securities, an amount for each
share of Series 2000 Non-Voting Preferred Stock then outstanding equal to the
Original Issue Price, plus any and all accrued unpaid dividends. If upon the
occurrence of such event, and after payment in full of the preferential amounts
with respect to the Senior Securities, the assets and funds available to be
distributed among the Holders of the Series 2000 Non-Voting Preferred Stock and
Parity Securities shall be insufficient to permit the payment to such Holders of
the full preferential amounts due to the Holders of the Series 2000 Non-Voting
Preferred Stock and the Parity Securities, respectively, then the entire assets
and funds of the Company legally available for distribution shall be distributed
among the Holders of the Series 2000 Non-Voting Preferred Stock and the Parity
Securities, pro rata, based on the respective liquidation amounts to which each
such series of stock is entitled by the Company's Certificate of Incorporation
and any certificate(s) of designation relating thereto.

              (b) Upon the completion of the distribution required by Section
4(a), if assets remain in the Company, they shall be distributed to holders of
Junior Securities in accordance with the Company's Certificate of Incorporation
including any duly adopted certificate(s) of designation relating thereto.

              (c) At each Holder's option, a sale, conveyance or disposition of
all or substantially all of the assets of the Company or the effectuation by the
Company of a transaction or series of related transactions in which any person
or entity acquires more than fifty percent (50%) of the voting power of the
Company (a "Change of Control") shall be deemed to be a Liquidation Event as
described in Section 4(a); provided further that (i) a consolidation, merger,
acquisition, or other business combination of the Company with or into any other
publicly traded company or companies shall not be treated as a Liquidation Event
as defined in Section 4(a), but instead shall

                                       3

<PAGE>   4

be treated pursuant to Section 5(d)(ii) hereof, (ii) the acquisition by Amphion
Ventures L.P., by itself or along with one or more of its affiliates, of more
than fifty percent (50%) of the voting power of the Company shall not be deemed
to be a Change of Control and, accordingly, will not be treated as a Liquidation
Event as defined in Section 4(a) and (iii) a consolidation, merger, acquisition
or other business combination of the Company with or into any other non_publicly
traded company or companies shall be treated as a Liquidation Event as defined
in Section 4(a). The Company shall not effect any transaction described in
Section 4(c)(ii) unless it first gives thirty (30) business days' prior notice
of such transaction (during which time the Holder shall be entitled to convert
its shares of Series 2000 Non-Voting Preferred Stock into non_voting Common
Stock). For purposes of this Section 4(c), the public offering, sale or
distribution of shares of stock (or assets) of the Company's Sandia Imaging
Systems Corporation subsidiary shall not be deemed to be a Liquidation Event.

              (d) In the event that, immediately prior to the closing of a
transaction described in Section 4(c) which would constitute a Liquidation
Event, the cash distributions required by Section 4(a) have not been made, the
Company shall either: (i) cause such closing to be postponed until such cash
distributions have been made, or (ii) cancel such transaction, in which event
the rights of the Holders of Series 2000 Non-Voting Preferred Stock shall be the
same as existing immediately prior to such proposed transaction.

         SECTION 5.  CONVERSION. The record Holders of this Series 2000
Non-Voting Preferred Stock shall have conversion rights as follows (the
"Conversion Rights").

              (a) Right to Convert. On the terms and subject to the conditions
set forth in this Certificate of Designation, each record Holder of Series 2000
Non-Voting Preferred Stock shall be entitled to convert the shares of Series
2000 Non-Voting Preferred Stock held by such Holder, in whole at any time and in
part from time to time, into a number of fully_paid and non_assessable shares of
non_voting Common Stock of the Company equal to the quotient of (i) the
aggregate Original Issue Price of the shares of Series 2000 Non-Voting Preferred
Stock being converted divided by (ii) the Conversion Price as determined
pursuant to this Section 5 (the "Conversion Price"). The Conversion Price shall
initially be THREE DOLLARS AND FIFTY CENTS ($3.50) per share of Series 2000
Non-Voting Preferred Stock. The Conversion Price shall be subject to adjustment
from time to time as provided in Section 5(d). Notwithstanding the foregoing or
any other term or provision of this Certificate of Designation, the Holder shall
not be permitted, without the prior written consent of the Company, to convert
any shares of the Series 2000 Non-Voting Preferred Stock to shares of non_voting
Common Stock until such time as the Company shall have received authorization of
its stockholders to issue shares of the Company's non_voting Common Stock to the
Holder upon the conversion by the Holder of any share of Series 2000 Non-Voting
Preferred Stock. The Company hereby agrees to submit such a proposal to its
stockholders for approval at the Company's 2000 annual meeting of stockholders
and to use its best efforts to obtain such approval.

              (b) Mechanics of Conversion. Subject to the terms of Section 5(a)
above, the conversion of shares of Series 2000 Non-Voting Preferred Stock may be
effected by written notice to the Company, and shall be effective upon receipt
of such notice by the Company, or as otherwise provided in such notice, and
delivery to the Company of (i) one or more certificates representing the shares
of Series 2000 Non-Voting Preferred Stock being converted, (ii) a certificate of
guaranteed

                                       4

<PAGE>   5

delivery of such certificates reasonably satisfactory to the Company, or (iii)
evidence of the loss, theft or destruction of such certificates pursuant to
Section 11 of this Certificate of Designation, together with any indemnity or
security reasonably requested by the Company pursuant to such Section 11. Upon
any conversion of shares of Series 2000 Non-Voting Preferred Stock pursuant to
this Section 5, the Holder shall be deemed to be the record holder of the shares
of non_voting Common Stock into which shares of Series 2000 Non-Voting Preferred
Stock have been converted and shall be entitled to receive duly executed
certificates, in proper form, representing such shares of non_voting Common
Stock as soon as practicable thereafter. Anything contained herein to the
contrary notwithstanding, if any conversion of shares of Series 2000 Non-Voting
Preferred Stock would create a fractional share of non_voting Common Stock or a
right to acquire a fractional share of non_voting Common Stock, such fractional
share shall be disregarded and the number of shares of non_voting Common Stock
issuable upon such conversion, in the aggregate, shall be rounded up to the
nearest whole number of shares.

              (c) Reservation of Stock Issuable Upon Conversion. The Company
shall at all times reserve and keep available out of its authorized but unissued
shares of non_voting Common Stock, solely for the purpose of effecting the
conversion of the Series 2000 Non-Voting Preferred Stock, such number of its
shares of non_voting Common Stock as shall from time to time be sufficient to
effect the conversion of all then outstanding Series 2000 Non-Voting Preferred
Stock. If at any time the number of authorized but unissued shares of non_voting
Common Stock (excluding for this purpose any authorized but unissued shares of
non_voting Common Stock that are properly reserved for some other purpose) shall
be insufficient to cause the conversion into non_voting Common Stock of all
shares of Series 2000 Non-Voting Preferred Stock then outstanding, the Company
will take such corporate action as may be reasonably necessary to increase its
authorized but unissued shares of non-voting Common Stock to such number of
shares as shall be sufficient for such purpose.

              (d) Adjustment to Conversion Price.

                   (i)  Adjustment to Conversion Price Due to Stock Split
Dividend, Etc. If, at any time that any shares of Series 2000 Non-Voting
Preferred Stock remain outstanding, the number of outstanding shares of
non-voting Common Stock is increased by a stock split, stock dividend, or other
similar event, the Conversion Price shall be proportionately reduced, or if the
number of outstanding shares of non-voting Common Stock is decreased by a
reverse stock split, combination or reclassification of shares, or other similar
event, the Conversion Price shall be proportionately increased.

                   (ii) Adjustment Due to Merger, Consolidation, Etc. If, at
any time that any shares of Series 2000 Non-Voting Preferred Stock remain
outstanding, there shall be any merger, consolidation, exchange of shares,
recapitalization, reorganization, or other similar event, as a result of which
shares of non-voting Common Stock of the Company shall be changed into the same
or a different number of shares of the same or another class or classes of stock
or securities of the Company or another entity, or there is a sale of all or
substantially all the Company's assets or there is a Change of Control not
deemed to be a Liquidation Event pursuant to Section 4(c), then the Holders
shall thereafter have the right to receive upon conversion of shares of Series
2000 Non-Voting Preferred Stock, upon the basis and upon the terms and
conditions specified herein and in lieu

                                       5

<PAGE>   6
of the shares of non-voting Common Stock immediately theretofore issuable upon
conversion, such stock, securities and/or other assets which the Holder would
have been entitled to receive in such transaction had such shares of Series 2000
Non-Voting Preferred Stock been converted immediately prior to such transaction,
and in any such case appropriate provisions shall be made with respect to the
rights and interests of the Holders of the Series 2000 Non-Voting Preferred
Stock to the end that the provisions hereof (including, without limitation,
provisions for the adjustment of the Conversion Price and of the number of
shares issuable upon conversion of the Series 2000 Non-Voting Preferred Stock)
shall thereafter be applicable, as nearly as may be practicable in relation to
any securities thereafter deliverable upon the exercise hereof. The Company
shall not effect any transaction described in this Section 5(d)(ii) unless (A)
it first gives thirty (30) business days' prior notice to Holders of such
merger, consolidation, exchange of shares, recapitalization, reorganization, or
other similar event (during which time the Holders shall be entitled to convert
their shares of Series 2000 Non-Voting Preferred Stock into non-voting Common
Stock) and (B) the resulting successor or acquiring entity (if not the Company)
assumes by written instrument the obligations of the Company under this
Certificate of Designation including this Section 5(d)(ii).

         SECTION 6. VOTING. The Holders shall not be entitled to vote on any
matter submitted to a vote of the stockholders of the Company, or as to which
the holders of the voting Common Stock shall otherwise be entitled to vote. As
used in this Section 6, all references to votes and voting shall refer as well
to action and actions by written consent.

         SECTION 7.  OPTIONAL REDEMPTION BY COMPANY. The Series 2000 Non-Voting
Preferred Stock shall be subject to the optional redemption by the Company, in
whole at any time or in part from time to time, at a redemption price per share
equal to the Original Issue Price, plus any and all accrued unpaid dividends
thereon. The Company shall give at least ten (10) days' prior written notice of
any redemption pursuant to this Section 7 to each Holder of shares of Series
2000 Non-Voting Preferred Stock to be redeemed. The Company's optional right of
redemption is subject to each Holder's right to convert all or any part of the
shares to be redeemed into non-voting Common Stock pursuant to Section 5,
provided that the Holder gives written notice of such conversion to the Company
in accordance with Section 5 within ten (10) business days after the Company's
notice of redemption. The Holders of Series 2000 Non-Voting Preferred Stock
shall not be entitled to any mandatory redemption of their Series 2000
Non-Voting Preferred Stock without the consent of the Company.

         SECTION 8.  MANDATORY CONVERSION BY COMPANY. Each share of Series 2000
Non-Voting Preferred Stock shall automatically convert into that number of
fully-paid and non_assessable shares of non-voting Common Stock of the Company
equal to the Original Issue Price plus all accrued, but unpaid dividends
thereon, divided by the Conversion Price (subject to adjustment from time to
time as provided in Section 5(d)), upon (a) the closing bid price per share of
the Common Stock on the Nasdaq SmallCap Market (or, if the Common Stock is not
then included in Nasdaq, but is listed on any national securities exchange, on
the principal national securities exchange on which the Common Stock is then
listed) having reached and remained above $7.50 per share for a period of twenty
(20) consecutive trading days and (b) the trading volume of the Common Stock on
Nasdaq or other securities exchange was at least 50,000 shares per day as
measured by Nasdaq or other securities exchange during each of such twenty (20)
consecutive trading days.

                                       6

<PAGE>   7

         SECTION 9. STATUS OF CONVERTED OR REDEEMED STOCK. In the event any
shares of Series 2000 Non-Voting Preferred Stock shall be converted pursuant to
either Section 5 or 8 hereof or redeemed pursuant to Section 7 hereof, the
shares so converted or redeemed shall be canceled, shall return to the status of
authorized but unissued Preferred Stock of no designated series, and shall not
thereafter be issuable by the Company as Series 2000 Non-Voting Preferred Stock.

         SECTION 10. OTHER PREFERRED STOCK. Nothing contained herein shall be
construed to prevent the Board of Directors from authorizing the creation of, or
to prevent the Company from issuing shares of, one or more series of Preferred
Stock junior to or on parity with the Series 2000 Non-Voting Preferred Stock as
to dividend, liquidation rights or otherwise.

         SECTION 11. LOST OR STOLEN CERTIFICATES. Upon receipt by the Company of
evidence of the loss, theft, destruction or mutilation of any certificates
representing shares of Series 2000 Non-Voting Preferred Stock, and (in the case
of loss, theft or destruction) of indemnity or security reasonably satisfactory
to the Company, and upon surrender and cancellation of the certificate(s), if
mutilated, the Company shall execute and deliver to the record Holder thereof
new certificate(s) of like tenor and date. However, the Company shall not be
obligated to re-issue such lost or stolen certificates if the Holder
contemporaneously requests the Company to convert such shares of Series 2000
Non-Voting Preferred Stock into shares of non-voting Common Stock.

         SECTION 12. FRACTIONAL SHARES. In the event a Holder of Series 2000
Non-Voting Preferred Stock shall be entitled to receive a fractional interest in
a share of Series 2000 Non-Voting Preferred Stock of less than one one-hundredth
of one share, except as otherwise provided herein, the Company shall either, in
the sole discretion of the Board of Directors, (a) round such fractional
interest up to the next one-hundredth of one whole share of Series 2000
Non-Voting Preferred Stock or (b) deliver cash in the amount of the fair market
value (as determined by the Board of Directors or in any manner prescribed by
the Board of Directors) of such fractional interest.

         SECTION 13. PREEMPTIVE RIGHTS. The Holders of Series 2000 Non-voting
Preferred Stock are not entitled to any preemptive or subscription rights in
respect of any securities of the Company.

         IN WITNESS WHEREOF, AXCESS Inc. has caused this certificate to be
signed by its Chief Financial Officer and attested by its Assistant Secretary,
as of the 29th day of December 1999.

AXCESS Inc.                                                    December 30, 1999

         Re:  Convertible Note dated September 30, 1999, executed by AXCESS Inc.
              (the "Company") payable to Amphion Ventures, L.P. ("Amphion

              "Convertible Note") and the Series A, B and C Preferred Stock
              Dividends

Ladies and Gentlemen:

         Under the terms of the Convertible Note, Amphion Ventures has the
option to convert all or a portion of the outstanding balance of the Convertible

Amphion Ventures and the Company hereby desire to amend the Convertible Note
such that $3,323,423.29 of the outstanding principal balance of the Convertible
Note shall be convertible into a new Series 2000 Non-Voting Preferred Stock
instead of the Series 1999 Non-Voting Preferred Stock. The balance of the
Convertible Note (up to $2,676,576.71) may, at the option of Amphion Ventures,
be convertible into shares of the Company's Series 1999 Non-Voting preferred
Stock.

         Amphion Ventures also desires to have the Company pay all accrued, but
unpaid dividends which are outstanding as of the date of this letter on the
shares of Series A, B, and C Convertible Preferred Stock of the Company held by
Amphion Ventures (approximately $94,500; collectively the "Accrued Dividends")
in kind by issuing to Amphion Ventures additional shares of Series A, B or C
Preferred Stock, respectively, of the Company. Further, Amphion Ventures would
like the Company to exchange the additional shares of Series A, B, and C
Convertible Preferred Stock of the Company for 9.45 shares of the Company's
Series J Non-Voting Preferred Stock.

         1. Amendment to Convertible Note; Conversion of Convertible Debt.
Amphion Ventures and the Company hereby agree to amend the Convertible Note by
permitting Amphion Ventures to convert $3,323,423.29 of the outstanding
principal balance of the Convertible Note into shares of the Company's Series
2000 Non-Voting Preferred Stock. The certificates of Designations, Preferences,
Powers and Rights of the Series 2000 Non-Voting Preferred Stock is attached
hereto as Exhibit "A." Accordingly, Amphion Ventures hereby elects to convert
$3,323,423.29 of the Convertible Note into 332.34 shares of the Series 2000
Non-Voting Preferred Stock (the "Series 2000 Shares"). Subject to Section 3
below, the Company hereby consents to the conversion and agrees to issue those
shares to Amphion Ventures. Other than as set forth in this Section 1, the
balance of the Convertible Note shall remain subject to the terms thereof.

         2. Payment of Accrued Dividends; Issuance of Shares. Amphion Ventures
hereby directs the Company to issue 9.45 shares of Series J Non-Voting Preferred
Stock in exchange for the shares of Series A, B and C Convertible Preferred
Stock, respectively, issued to Amphion Ventures as payment in full for the
Accrued Dividends (the "Series J Shares"). On and as of the date of this letter,
the Accrued Dividends shall automatically be converted and discharged in full
and Amphion

<PAGE>   2

                  5.1 The Company is a corporation duly organized, validly
existing and in good standing under the laws of the State of Delaware, and has
the corporate power and authority to execute and deliver this agreement, to

                  5.2 The execution and delivery by the Company of this letter
agreement, the issuance of the Shares, and the performance by the Company of its
obligations hereunder, have been duly authorized by all requisite corporate

or result in the creation or imposition of any lien, charge or encumbrance of

                  5.3 This letter agreement has been duly executed and delivered
by the Company and constitutes the valid and legally binding obligation of the
Company, enforceable in accordance with its terms, except to the extent the
enforceability hereof may be limited by applicable bankruptcy, moratorium or
similar laws affecting the rights of creditors generally.

                  5.4 Based in part upon the representations and warranties of
Amphion Ventures contained in this letter agreement, no registration or filing
with, or consent or approval of, or other action by, any federal, state or other
governmental department, commission, board, bureau, agency or instrumentality or
any third party is or will be necessary for the execution and delivery of this
agreement by the Company and the issuance of the Shares hereunder, other than
the filing of a notice of sale on Form D with the Securities and Exchange
Commission in accordance with the rules and regulations thereof under the
Securities Act.

                  5.5 The Shares are duly authorized, validly issued, fully paid
and non-assessable shares of Series J Non-Voting Preferred Stock or Series 2000
Non-Voting Preferred Stock, as the case may be, and are not subject to any
preemptive rights.

         6. Representations and Warranties of Amphion Ventures. Amphion Ventures
hereby represents and warrants to the Company as follows:

                  6.1 Amphion Ventures is acquiring the Shares for its own
account, for investment and not with a view to the distribution thereof within
the meaning of the Securities Act.

                  6.2 Amphion Ventures understands that the Shares have not been
registered under the Securities Act, by reason of their issuance by the Company
in transactions exempt from the registration requirements of the Securities Act,
and that the Shares must be held by Amphion Ventures indefinitely unless a
subsequent disposition thereof is registered under the Securities Act or is
exempt from such registration.

                  6.3 Amphion Ventures further understands that the exemption
from registration afforded by Rule 144 (the provisions of which are known to it)
promulgated under the Securities Act depends on the satisfaction of various
conditions, and that, if applicable, Rule 144 may afford the basis for sales
only in limited amounts, after compliance with the holding periods and other
provisions thereof.

                  6.4 Amphion Ventures understands that its investment hereunder
involves substantial risks and represents and warrants that it has made such
independent examinations and investigations of the Company as it has deemed
necessary in making its investment decision, and Amphion Ventures further
represents and warrants that it has had sufficient access to the officers,
directors, books and records of the Company as it has deemed necessary to
conduct such examination and investigation and make such investment decision.

                  6.5 Amphion Ventures is able to bear the economic risk of the
investment contemplated by this agreement and has such knowledge and experience
in financial and business matters that it is capable of evaluating the merits
and risks of the investment contemplated by this agreement.
