            SECTION 5. REPRESENTATIONS AND WARRANTIES. Borrower represents and
warrants to Lender that:

            5.1   Representations and Warranties. Borrower is a corporation duly
organized, existing and in good standing under the laws of the State of
Illinois, with full and adequate corporate power to carry on and conduct its
business as presently conducted. Borrower is duly licensed or qualified in all
foreign jurisdictions wherein the nature of its activities require such
qualification or licensing. The Articles of Incorporation and Bylaws of Borrower
have not been changed or amended since the most recent date that certified
copies thereof were delivered to Lender. The Borrower's state issued
organizational identification number is 54821824. The exact legal name of
Borrower is as set forth in the preamble to this Amendment, and Borrower
currently does not conduct, nor has it during the last five (5) years conducted,
business under any other name or trade name.

            5.2   Authorization. Borrower is duly authorized to execute and
deliver this Amendment, the Second Amended and Restated Note and the
Subordination Agreement and is and will continue to be duly authorized to
perform its obligations under the Loan Agreement, as amended hereby, and the
other Loan Documents.

            5.3   No Conflicting Agreements. The execution and delivery of this
Amendment, the Note and the Security Agreement and the performance by Borrower
of its obligations under the Loan Agreement, as amended hereby, and the other
Loan Documents do not and will not conflict with any provision of law or of the
Articles of Incorporation or Bylaws of Borrower or any agreement binding upon
Borrower.

            5.4   Validity and Binding Effect. The Loan Agreement, as amended
hereby, the Note and the Security Agreement are each legal, valid and binding
obligations of Borrower, enforceable against Borrower in accordance with their
respective terms, except as enforceability may be limited by bankruptcy,
insolvency or other similar laws of general application affecting

                                       5
<PAGE>

the enforcement of creditors' rights or by general principles of equity
limiting the availability of equitable remedies.

            5.5   Compliance with Loan Agreement. Except as set forth on a
Schedule of Exceptions attached hereto as Exhibit C (the "Schedule of
Exceptions") delivered herewith, the representations and warranties set forth in
clauses (a) through (k) and clauses (n) through (t) of Section 3 of the Loan
Agreement, are true and correct with the same effect as if such representations
and warranties had been made on the date hereof. In addition, Borrower has
complied with and is in compliance with all of the covenants set forth in the
Loan Agreement.

            5.6   Financial Statements. The Borrower has provided or made
available to the Lenders unaudited financial statements (including balance
sheet, income statement and statement of cash flows) for the years ended
December 31, 2002, December 31, 2003 and December 31, 2004, in each case, as
attached hereto as Exhibit D (collectively, the "Financial Statements"). The
Financial Statements have been prepared in accordance with generally accepted
accounting principles applied on a consistent basis throughout the periods
indicated, except that the unaudited Financial Statements may not contain all
footnotes required by generally accepted accounting principles and the absence
of such notes do not make those financial statements misleading. The Financial
Statements fairly present the financial condition and operating results of the
Borrower as of the dates, and for the periods indicated therein. Except as set
forth in the Financial Statements, the Borrower has no liabilities in excess of
$75,000, contingent or otherwise, other than (1) liabilities incurred in the
ordinary course of business subsequent to December 31, 2004, (2) obligations
under contracts and commitments incurred in the ordinary course of business and
not required under generally accepted accounting principles to be reflected in
the Financial Statements and (3) the Subordinated Loan, which, in the case if
clauses (i) and (ii) above, individually or in the aggregate, are not material
to the financial condition or operating results of the Borrower. Except as
disclosed in the Financial Statements, the Borrower is not a guarantor or
indemnitor of any indebtedness of any other person, firm or corporation. The
Borrower maintains and will continue to maintain a standard system of accounting
established and administered in accordance with generally accepted accounting
principles.

            5.7   Changes. Since December 31, 2004, there has not been:

                  i.    any damage, destruction or loss, whether or not covered
                        by insurance;

                  ii.   any waiver, cancellation, release or compromise by the

                        it;

                  iii.  any adverse change to a material contract;

                        employee;

                  vii.  receipt of notice that there has been a loss of, or

                           SECOND AMENDED AND RESTATED
                             SECURED PROMISSORY NOTE

      FOR VALUE RECEIVED, Silvon Software, Inc., an Illinois corporation (the
"Company"), promises to pay to the order of JDA Software Group, Inc., a Delaware
corporation (and any permitted successor(s) and assign(s) under Section 8
hereof, the "Holder"), the principal amount of ONE MILLION SEVEN HUNDRED
SIXTY-FIVE THOUSAND SIX HUNDRED NINETY-FIVE and 07/100 Dollars ($1,765,695.07)
together with interest thereon calculated from the date hereof in accordance
with the provisions of this Second Amended and Restated Secured Promissory Note.
Terms not defined herein shall have the meaning given them in the Secured Loan
Agreement dated as of May 8, 2001 between the Company and the Holder, as amended
by that certain First Amendment to Secured Loan Agreement dated as of November
30, 2004 between the Company and the Holder (as the same may hereafter be
amended, restated, supplemented or otherwise modified from time to time, the
"Loan Agreement"). Neither the foregoing reference to the Loan Agreement nor any
provisions thereof shall affect or impair the absolute and unconditional
obligation of the Company to pay the principal and interest on this Note as
provided herein.

      1.    Loan Agreement. This Second Amended and Restated Secured Promissory
Note (as amended or otherwise modified from time to time, the "Note") is the
Note called for by the Loan Agreement. The Holder is entitled to the benefits
of, and subject to the terms and conditions set forth in the Loan Agreement. The
benefits and rights of the Holder are also subject to certain conditions and
restrictions also set forth in the Loan Agreement, which conditions and
restrictions may be enforced against the Holder.

      2.    Maturity. The outstanding principal under this Note shall be due and
payable on March 30, 2006 (the "Maturity Date"). Notwithstanding the foregoing,
the entire unpaid principal sum of this Note, together with accrued and unpaid
interest thereon, shall become immediately due and payable upon any Event of
Default (as defined in the Security Agreement referred to in Section 3 hereof).

      3.    Security Interest and Collateral. This Note is secured by a first
priority security interest in all of the Company's assets pursuant to the terms
of the Amended and Restated Security Agreement dated November 30, 2004 by and
between the Company and the Holder (as

CHICAGO1228348
<PAGE>

amended, restated, supplemented or otherwise modified from time to time, the
"Security Agreement").

      4.    Interest.

            (a) The principal of this Note from time to time outstanding shall
bear interest on the unpaid principal amount of this Note outstanding from time
to time on a monthly basis from the date hereof (compounded monthly) at the rate
of eighteen percent (18%) per annum or the highest rate of interest then allowed
by law; provided, however, that upon an Event of Default and while that Event of
Default is continuing, the interest shall be the lesser of (i) twenty-one
percent (21%) or (ii) the highest rate of interest then allowed by law. All
interest on this Note shall be due and payable monthly on the first day of each
month, with the first interest payment due April 1, 2005.

            (b) Following an Event of Default, the Company shall pay to the
Holder on demand all reasonable expenses and expenditures (including, but not
limited to, reasonable fees and expenses of legal counsel) incurred or paid by
the Holder in exercising or protecting its interests, rights and remedies under
this Note, plus interest thereon at the lesser of (i) twenty-one percent (21%)
per annum or (ii) the highest rate of interest then allowed by law from the date
of such demand by the Holder until paid.

            (c) All agreements between Company and Holder, whether now existing
or hereafter arising and whether written or oral, are expressly limited so that
in no contingency or event whatsoever, whether by conversion, acceleration of
the maturity of this Note or otherwise, shall the amount paid, or agreed to be
paid, to the holder hereof for the use, forbearance or detention of the money to
be loaned hereunder or otherwise, exceed the maximum amount permissible under
applicable law. If from any circumstances whatsoever fulfillment of any
provision of this Note or of any other document evidencing, securing or
pertaining to the indebtedness evidenced hereby, at the time performance of such
provision shall be due, shall involve transcending the limit of validity
prescribed by law, then ipso facto, the obligation to be fulfilled shall be
reduced to the limit of such validity, and if from any such circumstances the
holder of this Note shall ever receive anything of value as interest or deemed
interest by applicable law under this Note or any other document evidencing,
securing or pertaining to the indebtedness evidenced hereby or otherwise an
amount that would exceed the highest lawful rate, such amount that would be
excessive interest shall be applied to the reduction of the principal amount
owing under this Note or on account of any other indebtedness of Company to
Holder relating to this Note, and not to the payment of interest, or if such
excessive interest exceeds the unpaid balance of principal of this Note and such
other indebtedness, such excess shall be refunded to Borrower. In determining
whether or not the interest paid or payable with respect to any indebtedness of
Company to Holder, under any specific contingency, exceeds the highest lawful
rate. Company and Holder shall, to the maximum extent permitted by applicable
law, (i) characterize any nonprincipal payment as an expense, fee or premium
rather than as interest, (ii) amortize, prorate, allocate and spread the total
amount of interest throughout the full term of such indebtedness so that the
actual rate of interest on account of such indebtedness is uniform throughout
the term thereof and/or (iii) allocate interest between portions of such
indebtedness, to the end that no such portion shall bear interest at a rate
greater than that

                                       2
<PAGE>

permitted by law. The terms and provisions of this paragraph shall control and
supersede every other conflicting provision of all agreements between Company
and Holder.

      5.    Payment. All payments shall be made in lawful money of the United
States of America without setoff, counterclaim, or other defense (other than as
provided in Section 6 hereof) at such place as the Holder hereof may from time
to time designate in writing to the Company; provided that all payments
hereunder shall be made notwithstanding the Company's audit right under Section
14 of the Distribution Agreement (as defined below). Payment shall be credited
first to attorney fees then due and payable, second to accrued interest then due
and payable, and the remainder applied to principal, except in the case of a new
investment under Section 7 hereof, which shall first be credited to principal
and only when the principal is completely paid shall any such amount be applied
to accrued interest. Prepayment of this Note may be made at any time, and from
time to time, without penalty or premium.

      6.    Royalties. 100% of the Royalties (as defined in the Distribution
Agreement dated as of May 8, 2001 between the Company and the Holder (as
amended, restated, supplemented or otherwise modified from time to time, the
"Distribution Agreement")) due to the Company under the Distribution Agreement
shall be retained by the Holder and applied first against accrued interest then
due and then to outstanding principal hereunder.

      7.    New Money. If the Company shall either receive an investment by a
third party investor or borrow money from a bank or other third party lender,
50% of such investment or loan must be paid by the Company to the Holder to
reduce the outstanding principal and interest hereunder.

      8.    Transfer; Successors and Assigns. The terms and conditions of this
Note shall inure to the benefit of and be binding upon the respective successors
and assigns of the parties. The obligations of the Company or the Holder under
this Note may not be assigned without the prior written consent of the other
party hereto which may be given or denied in their sole and absolute discretion.

      9.    Governing Law. This Note and all acts and transactions pursuant
hereto and the rights and obligations of the parties hereto shall be governed,
construed and interpreted in accordance with the laws of the State of New York,
without giving effect to principles of conflicts of law thereof.

      10.   Notices. Any notice required or permitted by this Note shall be in
writing and shall be deemed effectively given: (i) upon personal delivery to the
party to be notified; (ii) when sent by confirmed facsimile or electronic
transmission if received during normal business hours of the recipient on a
business day, or if not, then on the next business day; or (iii) one (1)
business day after deposit with a nationally recognized overnight courier,
specifying next business day delivery, with written verification of receipt. All
communications shall be sent to the Company and the Holder at the address as set
forth on the signature page hereof or at such other address as the Company or
the Holder may designate by ten (10) days advance written notice to the other
parties hereto.

      11.   Lost Documents. Upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of this Note or
any Note exchanged for it, and an indemnity agreement reasonably satisfactory to
the Company (in case of loss, theft or destruction) or surrender and
cancellation of such Note (in the case of mutilation), the Company, at its own
expense, will make and deliver in lieu of such Note a new Note of like tenor and
unpaid principal amount and dated as of the date to which interest has been paid
on the unpaid principal amount of the Note in lieu of which such new Note is
made and delivered.

      12.   Amendments and Waivers.  Any term of this Note may be amended or
waived only with the written consent of the Company and the Holder. Any waiver
by the Company or the Holder of a breach of any provision of this Note shall not
operate as or be construed to be a waiver of any other breach of such provision
or of any breach of any other provision of this Note. The failure of the Company
or the Holder to insist upon strict adherence to any term of this Note on one or
more occasions shall not be considered a waiver or deprive that party of the
right thereafter to insist upon strict adherence to that term or any other term
of this Note.

      13.   Waiver. The Company waives presentment and demand for payment,
notice of dishonor, protest and notice of protest, notice of nonpayment and
notice of acceleration of intent of acceleration of this Note. The right to
plead any and all statutes of limitations as a defense to any demands hereunder
or under the Security Agreement is hereby waived to the fullest extent permitted
by law, regardless of and without any notice, diligence, act or omission as or
with respect to the collection of any amount called for hereunder.

      14.   Invalidity. If any provision of this Note is invalid, illegal or
unenforceable, the balance of this Note shall remain in effect, and if any
provision is inapplicable to any person or circumstance, it shall nevertheless
remain applicable to all other persons and circumstances. In such an event, the
parties will in good faith attempt to effect the business agreement represented
by such invalidated term to the fullest extent permitted by law.

      15.   Attorneys' Fees. If an Event of Default occurs, the Holder shall be
entitled to receive and the Company (or its assignee) agrees to pay all costs of
collection incurred by the Holder, including, without limitation, reasonable
attorneys' fees for consultation, suit and/or settlement.

      16.   Remedies. The remedies of the Holder hereunder are governed by the
terms hereof and the Security Agreement.

      17.   Second Amended and Restated Secured Promissory Note. This Second
Amended and Restated Secured Promissory Note shall be in replacement of and in
substitution for that certain Amended and Restated Secured Promissory Note dated
November 30, 2004 in the original principal amount of $2,861,196.78, made by the
Company and payable to the order of JDA Software Group, Inc., as such note was
replaced and substituted by that certain Secured Promissory Note dated May 8,
2001 in the original principal amount of $3,500,000.00, made by the Company and
payable to the order of JDA Software Group, Inc. (the "Original Note"). The
indebtedness outstanding as of the date hereof evidenced by the Original Note is
continuing indebtedness, and nothing herein shall be deemed to constitute a
payment, settlement or novation of the Original Note, or to release or otherwise
adversely affect any lien, mortgage or security

<PAGE>

      to endorse or assign to the Senior Lender any items of payment received by
      any Subordinated Lender on account of the Junior Debt, each Subordinated
      Lender hereby irrevocably makes, constitutes and appoints the Senior
      Lender (and all persons designated by the Senior Lender for that purpose)
      as such Subordinated Lender's true and lawful attorney and agent-in-fact,
      to make such endorsement or assignment in such Subordinated Lender's name;
      and

Instruments, as well as certified copies of all other agreements, instruments
and documents hereafter evidencing any Junior Debt, in each case showing such
endorsement. The Subordinated Lenders represent and warrant to the Senior Lender
that the outstanding amount of Junior Debt evidenced by the Junior Debt
Instruments as of the date of this Subordination Agreement is $1,000,000.

      The Subordinated Lenders expressly waive all notice of the acceptance by
the Senior Lender of the subordination and other provisions of this
Subordination Agreement and all notices not specifically required pursuant to
the terms of this Subordination Agreement, and the Subordinated Lenders
expressly waive reliance by the Senior Lender upon the subordination and other
provisions of this Subordination Agreement as herein provided. The Subordinated
Lenders consent and agree that all Senior Debt shall be deemed to have been
made, incurred and/or continued at the request of the Subordinated Lenders and
in reliance upon this Subordination Agreement. The Subordinated Lenders agree
that the Senior Lender has made no warranties or representations with respect to
the due execution, legality, validity, completeness or enforceability of the
documents, instruments and agreements evidencing the Senior Debt, that the
Senior Lender shall be entitled to manage and supervise its financial
arrangements with the Borrower in accordance with its usual practices, without

Senior Lender arising out of (i) any and all actions which the Senior Lender
takes or omits to take (including without limitation actions with respect to the
occurrence of an event of default under any documents, instruments or agreements
evidencing the Senior Debt, and actions with respect to the collection of any
claim for all or any part of the Senior Debt from any account debtor, guarantor
or other person or entity) with respect to the documents, instruments and
agreements evidencing the Senior Debt or to the collection of the Senior Debt
(ii) the Senior Lender's election in any proceeding instituted under Chapter 11
of Title 11 of United States Code (11 U.S.C. Section 101 et. seq.) (the
"Bankruptcy Code"), of the application of

                                        3
<PAGE>

Section 1111(b)(2) of the Bankruptcy Code, and/or (iii) any borrowing or grant
of a security interest under Section 364 of the Bankruptcy Code by the Borrower,
as debtor-in-possession.

      The Subordinated Lenders agrees that the Senior Lender, at any time and
from time to time hereafter, may enter into such agreements with the Borrower as
the Senior Lender may deem proper extending the time of payment of or renewing
or otherwise altering the terms of all or any of the Senior Debt, and may
release any balance of funds of the Borrower with the Senior Lender, without
notice to the Subordinated Lenders and without in any way impairing or affecting
this Subordination Agreement.

      This Subordination Agreement shall be irrevocable and shall constitute a
continuing agreement of subordination and shall be binding on the Subordinated
Lenders and its heirs, personal representatives, successors and assigns, and
shall inure to the benefit of the Senior Lender, its successors and assigns
until the Senior Lender has, in writing, notified the Subordinated Lenders that
all of the Senior Debt has been paid in full in cash and all obligations arising
in connection therewith have been discharged. The Senior Lender may continue,
without notice to the Subordinated Lenders, to lend monies, extend credit and
make other accommodations to or for the account of the Borrower on the faith
hereof. The Subordinated Lenders hereby agree that all payments received by the
Senior Lender may be applied, reversed, and reapplied, in whole or in part, to
any of the Senior Debt, without impairing or affecting this Subordination
Agreement.

      The Subordinated Lenders hereby assume responsibility for keeping
themselves informed of the financial condition of the Borrower, any and all
endorsers and any and all guarantors of the Senior Debt and the Junior Debt and
of all other circumstances bearing upon the risk of nonpayment of the Senior
Debt and the Junior Debt that diligent inquiry would reveal, and the
Subordinated Lenders hereby agrees that the Senior Lender shall have no duty to
advise the Subordinated Lenders of information known to the Senior Lender
regarding such condition or any such circumstances or to undertake any
investigation not a part of its regular business routine. If the Senior Lender,
in its sole discretion, undertakes, at any time or from time to time, to provide
any information of the type described herein to the Subordinated Lenders, the
Senior Lender shall be under no obligation to subsequently update any such
information or to provide any such information to the Subordinated Lenders on
any subsequent occasion.

      No waiver shall be deemed to be made by the Senior Lender of any of its
rights hereunder unless the same shall be in writing signed on behalf of the
Senior Lender and each such waiver, if any, shall be a waiver only with respect
to the specific matter or matters to which the waiver relates and shall in no
way impair the rights of the Senior Lender or the obligations of the
Subordinated Lenders to the Senior Lender in any other respect at any other
time.

      THIS AGREEMENT SHALL BE GOVERNED AND CONTROLLED BY THE INTERNAL LAWS (AS
DISTINGUISHED FROM THE CONFLICTS OF LAW PROVISIONS) OF THE STATE OF NEW YORK.
