defined in Addendum A) to Customer. The effective date of this agreement (the
"Agreement Date") is April 29 2000.

1.       LICENSE GRANT AND USE. Subject to the terms and conditions of this
Agreement, and payment of the appropriate license fees, i2 hereby grants to
Customer a non-exclusive, non-transferable, license to use the machine readable
version of the software as identified in the applicable Addendum hereto
("Licensed Software"), which i2 delivers to Customer and the user manuals and
technical materials delivered to Customer (the "Documentation"), (the Licensed
Software, and Documentation are collectively referred to herein as the
"System") to process its data subject to the Site Location Users and/or Server
(collectively defined in Section 1.2) and other restrictions, if any, as
specified on the addenda attached to this Agreement. Use beyond the scope of
the license granted therein is subject to additional fees and requires an
amendment to this Agreement signed by both Customer and i2. Customer agrees to
allow i2, with reasonable prior notice, to enter Customer's premises during
normal business hours, or electronically access the System as installed at
Customer's location, to verify Customer's compliance with this Agreement.

1.1      THIRD PARTY SOFTWARE. The Customer acknowledges that the System may
include software which has been provided by third parties ("Third Party
Software") and the licensor of any Third Party Software embedded in the System
has a proprietary interest in such software. The license fees and costs
associated with Third Party Software shall be borne by i2.

1.2      SITE, SERVER AND USER DEFINITIONS. [Reserved.]

1.3      RIGHT TO COPY SYSTEM. Customer may copy the System for archival and/or
backup purposes only. Customer shall not otherwise, in whole or in part,
sublicense, copy, rent, loan, transfer, modify, enhance, prepare derivatives
of, decompile or reverse engineer the System or any copy of the System. Nothing
in this Section 1.3 shall be deemed to limit Customer's use of the Licensed
Software to support its business operations as a hosted service provider with
respect to its global trade communities in the Agribusiness Products (as
defined in Addendum A) industries as contemplated by the parties. Customer
shall not, in whole or in part, copy the Documentation except as expressly
permitted by this Agreement. Customer shall ensure that the proprietary,
copyright, trademark and trade secret notices contained in or placed upon the
System are affixed to the permitted copy in such manner and location as to give

<PAGE>   2

reasonable notice of the proprietary, copyright, trademark and trade secret

Agreement, Customer shall receive one set of Documentation per Site Location at

2.       CONFIDENTIALITY. Customer acknowledges that System is proprietary and
confidential material of i2. Customer shall not disclose, provide or otherwise
make available, the System or any other proprietary or confidential material of
i2, in whole or in part, except to Customer's employees or subcontractors in
the scope of their employment. Customer shall take appropriate action to
satisfy its obligations under this Agreement with respect to the use, copying,
protection and security of the System and all other proprietary or confidential
material of i2 or its licensor. Customer shall not disclose the contents of
this Agreement to any third party without the prior written consent of i2;
provided, however, that Customer may disclose as much of this Agreement as is
necessary to comply with the law and with the regulations of The Nasdaq
National Market System or other exchange. Customer acknowledges that in the
event of an actual or threatened violation of the foregoing provisions, i2 will
not have an adequate monetary remedy and shall be entitled to seek immediate
injunctive relief without any requirement to post bond, in addition to any
other available remedies. Any information disclosed by Customer to i2 and
identified by Customer as being confidential shall be subject to the same
degree of security, protection and confidentiality as i2 uses to preserve
information of a similar nature. Provisions of this Confidentiality paragraph
shall survive termination or expiration of this Agreement.

3.       MAINTENANCE. i2 reserves the right to alter its standard Maintenance
Services policy from time to time using reasonable discretion. i2 shall provide
Customer with sixty (60) days prior written notice of any material changes to

of the lower of one and one-half (1 1/2%) percent per month or as permitted by
law. All costs of collection, including reasonable attorney's and expert's fees
and costs of court, shall be paid by Customer.

6.       TAXES. License fees and all other amounts mentioned in this Agreement
do not include any sales, property, use, value added or ad valorem taxes, or
any other taxes, based upon this Agreement, all of which shall be paid by
Customer. In the event i2 is required to pay such taxes, Customer shall
reimburse i2. Customer shall withhold foreign withholding taxes only as
required by relevant local country tax law. Customer shall provide i2 with

7.       TERM AND TERMINATION. This Agreement shall be terminable three (3)

i2 and Customer. i2 or Customer may terminate this Agreement or any license
granted under this Agreement if the other party breaches any other provision of
this Agreement for any reason, which breach has not been cured within thirty
(30) days of written notice. Customer shall be obligated to pay all charges
which have accrued up to the date of termination. Upon termination for any
reason, Customer's license shall be revoked and Customer's rights under the
license shall cease. In the event of such termination, Customer shall
immediately de-install the System and promptly return to i2 the System, any and
all materials related to the System, and all proprietary and confidential
information of i2 held by Customer. Customer shall provide a certificate of

termination or expiration. These provisions include, but are not limited to,
Paragraphs 2, 8, 10, 11 and 12.

8.       OWNERSHIP. All rights, title, and interest, including trademarks,
patent rights, copyright interests, and other forms of intellectual property,

9.       PUBLICITY. Within thirty (30) days of the Agreement Date, i2 may, at
its option, upon Customers written approval, which will not be unreasonably
withheld, issue a press release to the general public announcing the license of
the System to Customer. In addition, upon Customers written approval, which
shall not be unreasonably withheld, i2 shall be permitted to bring in potential
i2 customers to Customer's Site Locations, provided such potential customers
are not direct Customer competitors and provided i2 maintains confidentiality
in accordance with Section 2 of this Agreement. The purpose is for Customer to
explain why the System was selected and the System's anticipated benefits.
Customer shall have the sole authority to determine the timing of each Site
Location visit.

10.      WARRANTY. i2 warrants to Customer that during the first eight (8)
months following the Agreement Date ("Warranty Period"), the System furnished
by i2 will function substantially in accordance with the Documentation
delivered to Customer under this Agreement. If during the Warranty Period, the
System does not function substantially in accordance with the Documentation,
Customer shall promptly notify i2 in writing of any claimed deficiency.
Provided that i2 determines that such deficiency exists and is i2's sole
responsibility, i2 shall, within thirty (30) days, (a) correct such deficiency;
(b) provide Customer with a plan acceptable to Customer for correcting the
deficiency; or (c) upon i2's determination that neither (a) nor (b) can be
accomplished, then i2 may terminate the license. If this license is terminated
under the provision of this Paragraph, Customer shall de-install the System and
return all copies of the System to i2. Upon return of the System, i2 shall
refund any license fees paid to i2 under this Agreement, including the return
of the Warrant executed by Customer pursuant to the terms of that certain
Warrant Purchase Agreement by and between i2 and Customer (the "Customer
Securities"). The preceding shall constitute i2's entire liability and
Customer's exclusive remedy for breach of the warranty set forth herein.

10.1.    WARRANTY LIMITATIONS. i2 MAKES NO OTHER WARRANTIES, EXPRESSED OR
IMPLIED, INCLUDING BUT NOT LIMITED TO, MERCHANTABILITY, SUITABILITY, OR FITNESS
FOR A PARTICULAR PURPOSE. i2 DOES NOT WARRANT THAT THE LICENSED SOFTWARE WILL
MEET CUSTOMER'S REQUIREMENTS OR OPERATE IN THE COMBINATIONS WHICH MAY BE
SELECTED

                                    Page 3
<PAGE>   4

FOR USE BY CUSTOMER, OR THAT THE OPERATION OF THE LICENSED SOFTWARE WILL BE
UNINTERRUPTED OR ERROR FREE.

11.      LIMITATION ON LIABILITY. THE PARTIES HAVE NEGOTIATED THIS AGREEMENT
WITH DUE REGARD FOR CUSTOMER'S BUSINESS RISK ASSOCIATED WITH ITS USE OF
LICENSED SOFTWARE. IN ANY EVENT, EITHER PARTY'S LIABILITY FOR DAMAGES UNDER
THIS AGREEMENT SHALL NOT EXCEED THE VALUE OF THE CUSTOMER SECURITIES ON THE
AGREEMENT DATE (AS SET FORTH ON ADDENDUM A), AND ANY LIABILITY THAT i2 MAY
INCUR MAY BE SATISFIED IN FULL BY THE RETURN TO CUSTOMER OF SUCH SECURITIES. IN
NO EVENT SHALL EITHER PARTY OR THE LICENSOR OF ANY THIRD PARTY SOFTWARE
EMBEDDED IN THE SYSTEM BE LIABLE FOR LOST PROFITS OR OTHER INCIDENTAL, SPECIAL,
EXEMPLARY OR CONSEQUENTIAL DAMAGES EVEN IF SUCH PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.

12.      INDEMNIFICATION. i2 represents that, to the best of i2's knowledge, as
of the Agreement Date, it is the owner or licensee of the System, that it has
the right to grant the license set forth in this Agreement, and that Customer's
use of the System in accordance with the terms of this Agreement do not
infringe upon any third party's copyright, patent or trade secret. i2 shall
indemnify and hold Customer harmless against liability to third parties (only
for liability solely the fault of i2) arising from the violation of any third
party's trade secrets, proprietary rights, copyright or patent rights in
connection with the use by Customer of the System (a) as delivered by i2 to
Customer herein or as modified by i2 (but not Customer) and (b) in accordance
with the Documentation and this Agreement, provided that (i) i2 shall have the
right to conduct any defense and/or settlement in any such third party action
arising as described herein, (ii) Customer shall fully cooperate with such
defense, and (iii) i2 receives prompt written notice from Customer. This
indemnification is limited to the System delivered to Customer or as modified
by i2 and does not cover third party claims arising from modifications not
authorized by i2 or its licensor. i2 shall have no liability for any claim of
infringement based on (a) use of other than a current release of the System if
such infringement would have been avoided by use of a current release, or (b)
use or combination of the System with non i2 software or data if such
infringement would have been avoided by the use of the System without the use
of other software or data.

12.1.    If a third party's claims substantially interfere with Customer's use
of the System or if i2 believes that a third party claim may substantially
interfere with Customer's use of the System, i2, at its sole discretion, may
(a) replace the System, without additional charge, with a functionally
equivalent and non-infringing product; (b) modify the System to avoid the
infringement; (c) obtain a license for the Customer to continue use of the
System and pay any additional fee required for such license: or (d) if none of
the foregoing alternatives are commercially reasonable, i2 may terminate the
license for the infringing software. In such event Customer shall de-install
the infringing software and return all copies to i2. Upon return, i2 shall
refund to Customer a prorated portion of the Customer Securities related to the
infringing software. For every year following the Agreement Date, the
refundable portion of the Customer Securities shall be reduced by 25%. The
licensor of any Third Party Software is excluded from liability under this
Agreement and Customer shall look solely to i2 for liabilities relating to the
System. The Section 12 shall constitute i2's entire liability and Customer's
exclusive remedy for a claim of infringement.

13.      EXPORT OF SYSTEM. Customer agrees that it will not, directly or
indirectly, export or reexport, or knowingly permit the export or re-export of,
the System, or any technical information about the System, to any country for
which the United States Export Administration Act, any regulation thereunder,
or any similar United States law or regulation, requires an export license or
other United States Government approval, unless the appropriate export license
or approval has been obtained.

14.      MISCELLANEOUS. This Agreement, including Addendum A, Addendum B, and
Addendum C, attached hereto and made a part hereof, may be modified or amended
only by a written instrument signed by duly authorized representatives of both
Customer and i2. Customer may not, without the prior written

<PAGE>   5

consent of i2, assign or transfer this Agreement or any obligation incurred
herein; provided that any factoring or assignment of receivables shall not be
treated as an assignment for this purpose. Any attempt to do so in
contravention of this Section shall be void and of no force and effect. The
pre-printed terms and conditions of any purchase order or other ordering
document issued by Customer in connection with this Agreement which are in
addition to or inconsistent with the terms and conditions of this Agreement
shall not be binding on i2 and shall not be deemed to modify this Agreement. No
term or provision contained herein shall be deemed waived and no breach excused
unless such waiver or consent shall be in writing and signed by i2. Neither
party hereto shall be liable to the other for any failure, delay or
interruption in the performance of any of the terms or conditions contained in
this Agreement due to causes entirely beyond the control of that party,
including, without limiting the generality of the foregoing, strikes, boycotts,
labor disputes, embargoes, acts of God, acts of public enemy, acts of
governmental authority, floods, riots or rebellion. This Agreement shall be
governed by and construed in accordance with the laws of the State of Texas.
The parties agree that any action regarding this Agreement shall be brought
exclusively in the state or federal courts located in the State of Texas. All
notices which either party hereto is required or may desire to give the other
herein shall be given by addressing the communication to the address set forth
on the first page of this Agreement, and shall be given by certified or

THE SYSTEM, CONSULTING AND MAINTENANCE TO BE FURNISHED HEREIN. THIS AGREEMENT

terms of the attached Addenda, the terms of the Addenda shall take precedence
to the extent of the inconsistency.

Lender in writing prior to the date hereof or as set forth in documents filed
with the United States Securities and Exchange Commission.

or any proceedings by or before any governmental or regulatory authority or
agency now pending or, to the knowledge of the Borrower, threatened against the
Borrower, in which there is a probability of an adverse decision that could
materially and adversely affect the financial condition of the Borrower or its
operations or business taken as a whole, except as otherwise specifically
disclosed to the Lender in writing prior to the date hereof.

                  6.04. No Breach. None of the execution and delivery of the
Loan Documents, the consummation of the transactions therein contemplated and
compliance with the terms and provisions thereof will conflict with or result
in a breach of, or require any consent under any applicable law or regulation,
or any order, writ, injunction or decree of any court or governmental authority
or agency, or any agreement or instrument to which the Borrower is a party or
by which it is bound or to which it is subject, or constitute a default under
any such agreement or instrument, or result in the creation or imposition of
any Lien upon any of the revenues or assets of the Borrower pursuant to the
terms of any such agreement or instrument.

                  6.05. Authority. The Borrower has all necessary authority to
execute, deliver and perform its obligations under the Loan Documents. The
execution, delivery and performance by the Borrower of the Loan Documents have
been duly authorized by all necessary action on its part, and this Agreement
constitutes, and the Note when executed and delivered will constitute, the
legal, valid and binding obligations of the Borrower, enforceable in accordance
with their respective terms.

                  6.06. Approvals. No authorizations, approvals or consents of,
and no filings or registrations with, any governmental or regulatory authority

federal and Florida state tax returns and all other tax returns that are
required to be filed by it and has paid all taxes due pursuant to such returns
or pursuant to any assessment received by such party, except such taxes, the
payment of which is not yet due, or which if due, is not yet delinquent or is
being contested in good faith or which has not been finally determined. The
charges, accruals and reserves on the books of the Borrower in respect of taxes
and other governmental charges are, in the opinion of the Borrower, adequate in
all respects.

Exhibit A
to Loan Agreement

                                PROMISSORY NOTE

$10,000,000                                                    March 24, 2000

                  FOR VALUE RECEIVED, VITECH AMERICA, INC. a Florida
corporation (the "Borrower"), hereby unconditionally promises to pay to the
order of GATEWAY COMPANIES, INC. (the "Lender"), at its head office at 4545
Towne Centre Court, San Diego, CA 92121, the principal sum of TEN MILLION
DOLLARS ($10,000,000) (or such lesser amount as shall equal the unpaid
principal amount of the Loan made by the Lender to the Borrower under the Loan
Agreement referred to below), in lawful money of the United States of America
and in immediately available funds, on or before March 24, 2001 (the "Maturity
Date") and as provided in the Loan Agreement referred to below, and to pay
interest on the unpaid principal amount of the Loan, in like money and funds at
such office, for the period commencing on the date of the Loan until the Loan
shall be paid in full, at the rate per annum of ten percent (10%) and on the
dates provided in such Loan Agreement.

                  This Promissory Note is the Note referred to in the Loan
Agreement dated as of the date hereof between the Borrower and the Lender (as
in effect from time to time, the "Loan Agreement"), and evidences the Loan made
thereunder. Unless otherwise defined herein, capitalized terms used in this
Promissory Note have the respective meanings assigned to them in the Loan
Agreement.

         Unless all or part of the principal amount of the Loans is converted
to the Borrower's Common Stock by the Lender on or before the Maturity Date as
provided for herein, all outstanding principal of the Loan and accrued interest
thereon shall be due and payable, and the Loan shall mature, on the Maturity
Date.
                  Conversion: Subject to the terms and conditions of this
Promissory Note, upon the occurrence and during the continuance of an Event of
Default, at the option and upon demand of the Lender the outstanding principal
of the Loan plus all interest accrued thereon is convertible, in whole or in
part, into Common Stock of the Borrower as follows:

                  1. Mechanics of Conversion. The Lender shall notify the
Borrower in writing (the "Conversion Notice"), in the manner prescribed in
Section 9.02 of the Loan Agreement, of its desire to convert all or part of the
aggregate amount of principal of the Loan or interest accrued thereon, as
applicable, into Common Stock of the Borrower. The Conversion Notice shall
specify (i) the aggregate amount of principal of the Loan and/or interest
accrued thereon to be converted (the "Conversion Amount"), and (ii) the name(s)
which should appear on the stock certificate(s) to be issued by the Borrower
which represent the Common Stock acquired by the Lender upon conversion.

                  2. Common Stock Issuable Upon Conversion. Within three (3)
Business Days of receipt of a Conversion Notice, the Borrower shall issue to
the Lender that number of shares of Common Stock of the Lender, no par value,
determined by dividing the Conversion Amount by a price (the "Conversion
Price") determined from time to time and subject to adjustment as set forth in
this Promissory Note. For purposes hereof, the Conversion Price as of any date
of determination shall be the average of the VWACS during the thirty (30)
consecutive Trading Days immediately preceding such date of determination. For
purposes hereof, "VWACS" shall mean the weighted daily average bid price per
share of the Common Stock on the Nasdaq National Market ("NASDAQ") or on the
New York Stock Exchange, American Stock Exchange or the Nasdaq SmallCap Market
(each, a "Subsequent Market") as reported by Bloomberg Information Services,
Inc., or its successors to its function of reporting prices, and "Trading Day"
shall mean (i) a day on which the Common Stock is traded on the NASDAQ or on
such Subsequent Market on which the Common Stock is then listed or quoted, as
the case may be, or (ii) if the Common Stock is not listed on the NASDAQ or on
a Subsequent Market, a day on which the Common Stock is traded in the
over-the-counter market, as reported by the OTC Bulletin Board, or (iii) if the
Common Stock is not quoted on the OTC Bulletin Board, a day on which the Common
Stock is quoted in the over-the-counter market as reported by the National
Quotation Bureau Incorporated (or any similar organization or agency succeeding
its functions of reporting prices); provided, however, that in the event the
Common Stock is not listed or quoted as set forth in (i), (ii) or (iii) hereof,
then "Trading Day" shall mean any day except Saturday, Sunday and any day which
shall be a legal holiday or a day on which banking institutions in the State of
New York are authorized or required by law or other government action to close.

                  A. Adjustment for Stock Splits and Combinations. If, during
any period of 30 Trading Days referenced in determination of a Conversion
Price, the Borrower effects a subdivision of its outstanding Common Stock, the
VWACS for such Trading Days prior to such subdivision shall be proportionately
decreased to account for subdivision. Conversely, if during any period of 30
Trading Days referenced in determination of a Conversion Price, the

                                       9
<PAGE>   11

Borrower combines the outstanding shares of Common Stock into a smaller number
of shares, the VWACS for such Trading Days prior to such combination shall be
proportionately increased.

                  B. Adjustment for Common Stock Dividends and Distributions.
If. during any period of 30 Trading Days referenced in determination of a
Conversion Price, the Borrower makes, or fixes a record date for the
determination of holders of Common Stock entitled to receive, a dividend or
other distribution payable in additional shares of Common Stock, in each such
event the VWACS for such Trading Days prior to the date of such issuance or
record date shall be proportionately decreased, by multiplying each such VWACS
by a fraction (i) the numerator of which is the total number of shares of
Common Stock issued and outstanding immediately prior to the time of such
issuance or the close of business on such record date, and (ii) the denominator
of which is the total number of shares of Common Stock issued and outstanding
immediately prior to the time of such issuance or the close of business on such
record date plus the number of shares of Common Stock issuable in payment of
such dividend or distribution.

                  C. Adjustment for Reclassification, Exchange and
Substitution. If, during any period of 30 Trading Days referenced in
determination of a Conversion Price, the Common Stock issuable upon the
conversion of the principal of and/or interest on the Loan is changed into the
same or a different number of shares of any class or classes of stock, whether
by recapitalization, reclassification or otherwise (other than a
reorganization, merger, consolidation or sale of assets provided for elsewhere
in this Section 2), in any such event the holder of this Promissory Note shall
have the right thereafter to convert the principal of and/or interest on the
Loan into the kind and amount of stock and other securities and property
receivable upon such recapitalization, reclassification or other change by
holders of the maximum number of shares of Common Stock into which the
principal of and/or interest on the Loan could have been converted immediately
prior to such recapitalization, reclassification or change, all subject to
further adjustment as provided herein or with respect to such other securities
or property by the terms thereof.

                  D. Reorganizations, Mergers, Consolidations or Sales of
Assets. If, during any period of 30 Trading Days referenced in determination of
a Conversion Price, there is a capital reorganization of the Common Stock
(other than a recapitalization, subdivision, combination, reclassification,
exchange or substitution of shares provided for elsewhere in this Section 2),
as a part of such capital reorganization, provision shall be made so that the
holder of this Promissory Note shall thereafter be entitled to receive upon
conversion of the principal of and/or interest on the Loan the number of shares
of stock or other securities or property of the Borrower to which a holder of
the number of shares of Common Stock deliverable upon conversion would have
been entitled on such capital reorganization, subject to adjustment in respect
of such stock or securities by the terms thereof. In any such case, appropriate
adjustment shall be made in the application of the provisions of this Section 2
with respect to the rights of the holder of this Promissory Note after the
capital reorganization to the end that the provisions of this Section 2
(including adjustment of the Conversion Price then being determined and the
number of shares issuable upon conversion of the principal of and/or interest
on the Loan) shall be applicable after that event and be as nearly equivalent
as practicable.

                  E. Sale of Shares Below Conversion Price.

                  (I) If, during any period of 30 Trading Days referenced in
determination of a Conversion Price, the Borrower issues or sells, or is deemed
by the express provisions of this subsection f to have issued or sold,
Additional Shares of Common Stock (as defined in subsection (iv) below)), other
than as a dividend or other distribution on any class of stock as provided in
Sections 2(b) or 2(c) above, and other than a subdivision or combination of
shares of Common Stock as provided in Section 2(a) above, for an Effective
Price (as defined in subsection f(iv) below) less than the average of the VWACS
during the ten (10) consecutive Trading Days immediately preceding such date of
issuance or sale, then and in each such case the VWACS for such Trading Days
prior to such issuance or sale shall be decreased, as of the opening of
business on the date of such issuance or sale, to a price equal to the
Effective Price for the Additional Shares of Common Stock.

                  (II) For the purpose of making any adjustment required under
this Section 2(e), the consideration received by the Borrower for any issue or
sale of securities shall (A) to the extent it consists of cash, be computed at
the net amount of cash received by the Borrower after deduction of any
underwriting or similar commissions, compensation or concessions paid or
allowed by the Borrower in connection with such issue or sale but without
deduction of any expenses payable by the Borrower, (B) to the extent it
consists of property other than cash, be computed at the fair value of that
property as determined in good faith by the Board of Directors, and (C) if
Additional Shares of Common Stock, Convertible Securities (as defined in
subsection e(iii) below) or rights or options to purchase either Additional
Shares of Common Stock or Convertible Securities are issued or sold together
with other stock or securities or other assets of the Borrower for a
consideration which covers both, be computed as the portion of the
consideration so received that may be

                                      10
<PAGE>   12

reasonably determined in good faith by the Board of Directors to be allocable
to such Additional Shares of Common Stock, Convertible Securities or rights or
options.

                  (III) For the purpose of the adjustment required under this
Section 2(e), if the Borrower issues or sells any (i) stock or other securities
convertible into Additional Shares of Common Stock (such convertible stock or
securities being herein referred to as "Convertible Securities") or (ii) rights
or options for the purchase of Additional Shares of Common Stock or Convertible
Securities, and if the Effective Price of such Additional Shares of Common
Stock is less than the average of the VWACS during such referenced Trading Days
prior to the date of issuance or sale, in each case the Borrower shall be
deemed to have issued at the time of the issuance of such rights or options or
Convertible Securities the maximum number of Additional Shares of Common Stock
issuable upon exercise or conversion thereof and to have received as
consideration for the issuance of such shares an amount equal to the total
amount of the consideration, if any, received by the Borrower for the issuance
of such rights or options or Convertible Securities, plus, in the case of such
rights or options, the minimum amounts of consideration, if any, payable to the
Borrower upon the exercise of such rights or options, plus, in the case of
Convertible Securities, the minimum amounts of consideration, if any, payable
to the Borrower (other than by cancellation of liabilities or obligations
evidenced by such Convertible Securities) upon the conversion thereof; provided
that if in the case of Convertible Securities the minimum amounts of such
consideration cannot be ascertained, but are a function of antidilution or
similar protective clauses, the Borrower shall be deemed to have received the
minimum amounts of consideration without reference to such clauses; provided
further that if the minimum amount of consideration payable to the Borrower
upon the exercise or conversion of rights, options or Convertible Securities is
reduced over time or on the occurrence or non-occurrence of specified events
other than by reason of antidilution adjustments, the Effective Price shall be
recalculated using the figure to which such minimum amount of consideration is
reduced; provided further that if the minimum amount of consideration payable
to the Borrower upon the exercise or conversion of such rights, options or
Convertible Securities is subsequently increased, the Effective Price shall be
again recalculated using the increased minimum amount of consideration payable
to the Borrower upon the exercise or conversion of such rights, options or
Convertible Securities. No further adjustment of the VWACS for the relevant
Trading Days, as adjusted upon the issuance of such rights, options or
Convertible Securities, shall be made as a result of the actual issuance of
Additional Shares of Common Stock on the exercise of any such rights or options
or the conversion of any such Convertible Securities. If any such rights or
options or the conversion privilege represented by any such Convertible
Securities shall expire without having been exercised, the VWACS as adjusted
upon the issuance of such rights, options or Convertible Securities shall be
readjusted to the VWACS for the relevant Trading Days which would have been in
effect had an adjustment been made on the basis that the only Additional Shares
of Common Stock so issued were the Additional Shares of Common Stock, if any,
actually issued or sold on the exercise of such rights or options or rights of
conversion of such Convertible Securities, and such Additional Shares of Common
Stock, if any, were issued or sold for the consideration actually received by
the Borrower upon such exercise, plus the consideration, if any, actually
received by the Borrower for the granting of all such rights or options,
whether or not exercised, plus the consideration received for issuing or
selling the Convertible Securities actually converted, plus the consideration,
if any, actually received by the Borrower (other than by cancellation of
liabilities or obligations evidenced by such Convertible Securities) on the
conversion of such Convertible Securities; provided that such readjustment
shall not apply to prior conversions of the principal of or interest on the
Loan.

                  (IV) "Additional Shares of Common Stock" shall mean all
shares of Common Stock issued by the Borrower or deemed to be issued pursuant
to this Section 2(e), whether or not subsequently reacquired or retired by the
Borrower other than (A) shares of Common Stock issued upon conversion of the
principal of and/or interest on the Loan; (B) shares of Common Stock and/or
options, warrants or other Common Stock purchase rights and the Common Stock
issued pursuant to such options, warrants or other rights (as adjusted for any
stock dividends, combinations, splits, recapitalizations and the like) after
the Closing Date to employees, officers or directors of, or consultants or
advisors to the Borrower or any subsidiary pursuant to stock purchase or stock
option plans (such plans being approved by at least one of the non-employee
directors of the Borrower) or other arrangements that are approved by the Board
of Directors of the Borrower (including at least one of the non-employee
directors of the Borrower); and (C) shares of Common Stock issued pursuant to
the exercise of options, warrants or convertible securities outstanding as of
the Closing Date. The "Effective Price" of Additional Shares of Common Stock
shall mean the quotient determined by dividing the total number of Additional
Shares of Common Stock issued or sold, or deemed to have been issued or sold by
the Borrower under this Section 2(e), into the aggregate consideration
received, or deemed to have been received by the Borrower for such issue under
this Section 2(e), for such Additional Shares of Common Stock.

                  F. Adjustment following Event of Default. Upon the occurrence
and during such time as any Event of Default shall have occurred and shall
continue unremedied or unwaived, the Conversion Price shall, subject to other
or additional adjustments as provided in this Section 2, be equal to the lesser
of (1) $9.75 and (2) the product of (x) 0.88 multiplied by (y) the average of
the lowest ten (10) VWACS during the thirty (30) consecutive Trading Days
immediately preceding the relevant date of conversion.

                                      11
<PAGE>   13

                  G. Certificate of Adjustment. In each case of determination
of or adjustment to the Conversion Price for the number of shares of Common
Stock or other securities issuable upon conversion of the principal of and/or
interest on the Loan, the Borrower, at its expense, shall compute such
adjustment or readjustment in accordance with the provisions hereof and prepare
a certificate showing such adjustment or readjustment, and shall mail such
certificate pursuant to the notice provisions of Section 9.02 of the Loan
Agreement. The certificate shall set forth such adjustment or readjustment,
showing in detail the facts upon which such adjustment or readjustment is
based.

                  H. Notices of Record Date. Upon (i) any taking by the
Borrower of a record of the holders of any class of securities for the purpose
of determining the holders thereof who are entitled to receive any dividend or
other distribution, or (ii) any consolidation or merger of the Borrower with or
into any other corporation or other entity or other capital reorganization of
the Borrower, any reclassification or recapitalization of the capital stock of
the Borrower, any merger or consolidation of the Borrower with or into any
other corporation, or any sale, lease or other disposition of all or
substantially all of the assets of the Borrower or any voluntary or involuntary
dissolution, liquidation or winding up of the Borrower, the Borrower shall
deliver notice to the holder of this Promissory Note (pursuant to the
provisions of Section 9.02 of the Loan Agreement) at least fifteen (15) days
prior to the record date specified therein a notice specifying (A) the date on
which any such record is to be taken for the purpose of such dividend or
distribution and a description of such dividend or distribution, (B) the date
on which any such reorganization, reclassification, transfer, consolidation,
merger, sale, lease, dissolution, liquidation, winding up or other disposition
is expected to become effective, and (C) the date, if any, that is to be fixed
as to when the holders of record of Common Stock (or other securities) shall be
entitled to exchange their shares of Common Stock (or other securities) for
securities or other property deliverable upon such reorganization,
reclassification, transfer, consolidation, merger, sale, lease, dissolution,
liquidation, winding up or other disposition.

                  I. Fractional Shares. No fractional shares of Common Stock
shall be issued upon conversion of the principal of and interest on the Loan.
If, in the aggregate, any conversion would result in the issuance of any
fractional share, the Borrower shall, in lieu of issuing the fractional share,
pay cash equal to the product of such fraction multiplied by the Common Stock's
fair market value (as determined by the closing price of the Common Stock on
the principal securities exchange or market on which it is then being listed)
on the date of conversion.

                  J. Reservation of Stock Issuable Upon Conversion. The
Borrower 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 principal of and/or interest on the Loan, such number of its
shares of Common Stock as shall from time to time be sufficient to effect the
conversion of all outstanding principal of and accrued but unpaid interest on
the Loan. If at any time the number of authorized but unissued shares of Common
Stock shall not be sufficient to effect a conversion of principal of and
accrued but unpaid interest on the Loan, the Borrower 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.

                  K. No Dilution or Impairment. Without the consent of the
holder of this Promissory Note, the Borrower shall not amend its articles of
incorporation (except as necessary to comply with the terms of the Loan
Agreement or the Convertible Loan Agreement) or participate in any
reorganization, transfer of assets, consolidation, merger, dissolution, issue
or sale of securities or take any other voluntary action, for the purpose of
avoiding or seeking to avoid the observance or performance of any of the terms
to be observed or performed hereunder by the Borrower, but shall at all times
in good faith assist in carrying out all such action as may be reasonably
necessary or appropriate in order to protect the conversion rights of the
holder of this Promissory Note against dilution or other impairment.

                  Upon the occurrence of an Event of Default, the principal
hereof and accrued interest hereon shall become, or may be declared to be,
forthwith due and payable in the manner, upon the conditions and with the
effect provided in the Loan Agreement.

                  The transfer of this Promissory Note may be registered on the
books maintained for that purpose by or on behalf of the Borrower.

                  None of the terms or provisions of this Promissory Note may
be amended, modified or waived except by a written agreement duly executed on
behalf of the Lender and the Borrower and specifically setting forth the
provision so amended, modified or waived. No course of dealing between the
Lender and the Borrower shall operate as a waiver of any right of any holder
hereof and no delay on the part of the holder hereof in exercising any right
hereunder shall so operate.

                  The Borrower hereby waives presentment and demand for
payment, notice of dishonor, protest and notice of protest of this Promissory
Note, and shall pay all costs of collection when incurred, including, without
limitation, reasonable attorneys' fees, costs and other expenses.

                  The Borrower may prepay all or any part of the principal
amount of the Loan evidenced by this Promissory Note as provided in the Loan
Agreement. Notice by the Borrower to the Lender of intent to effect such
prepayment shall represent a bona-fide prepayment commitment under this
Promissory Note, with the prepayment amount set forth therein deemed due and
payable by the Borrower on the prepayment date set forth in the notice.

                  THIS NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE
WITH, THE LAW OF THE STATE OF NEW YORK.
