Disclosure Schedule, Seller or IRI, as applicable, has good and marketable
title to, or a valid leasehold interest in, all the Assets free and clear of
all claims of any kind (other than taxes not yet due and payable), or

have in all material respects performed all the obligations required to be
performed by them to date and are not in default in any material respect

governmental or other licenses, franchises, consents, authorizations or permits
necessary for the conduct of the Logistics Business and the consummation of the

         (d)  Seller and IRI acknowledge that their sole remedy against
Purchaser and/or Manugistics for any matters arising out of this Agreement and
the Services Subcontract is as set forth in this Article VII and further that
with respect to any of the Other Agreements (other than the Services
Subcontract) the rights and remedies of the parties thereto shall be governed

under this Article VII by the Seller and IRI to Purchaser and Manugistics on
the one hand, and by Purchaser and





                                       39
<PAGE>   41
Manugistics to Seller and IRI on the other, shall not exceed $1,500,000, except
(i) in the event and to the extent of fraud or any willful misrepresentation by
a party with respect to any statement made by such party in this Agreement or
in the certificates delivered by a party pursuant to Section 5.02 and 6.02 of
this Agreement; (ii) in the event and to the extent of any willful breach by
any party of any covenant or obligation in this Agreement; (iii) in the event
and to the extent that Seller and/or IRI breaches (whether by fraud, willful
misrepresentation, or otherwise) the representations and warranties contained
in Section 3.01(e); and (iv) with respect to Damages arising from any claims
asserted by third parties relating to the matters governed by Section 7.01(a)
and 7.01(c) hereof.

         (f) Waiver of Certain Damages.  Each of Seller, IRI, Purchaser and
Manugistics, to the fullest extent permitted by law, irrevocably waives any
rights that it may have to punitive, multiple or consequential damages based on
or arising out of this Agreement, the Services Subcontract, or any course of
conduct, course of dealing, statements or actions of any of them related
thereto, provided, however, that nothing in this Section 7.01(f) shall operate
to prevent an Indemnified Party (as hereinafter defined) from seeking
indemnification from the Indemnifying Party (as hereinafter defined) under this
Article VII for punitive, multiple or consequential damages claimed by a third
party.

      Section 7.02. Procedure for Indemnification.

         (a) The party or parties claiming indemnification (individually or
collectively, the "Indemnified Party") shall promptly give notice hereunder to
the indemnifying party or parties (individually or collectively, the
"Indemnifying Party") as the case may be, after obtaining knowledge of any
claim as to which recovery may be sought against the Indemnifying Party because
of the indemnity in Section 7.01, and, if such indemnity shall arise from the
claim of a third party, shall permit the





                                       40
<PAGE>   42
Indemnifying Party to assume the defense of any such claim, provided that the
Indemnified Party shall not be required to permit the Indemnifying Party to
assume the defense of any third party claim which if not first paid, discharged
or otherwise complied with would result in an interruption or cessation of the
conduct of the business by the Indemnified Party.  Notwithstanding the
foregoing notice requirement, the right to indemnification hereunder shall not
be affected by a failure of the Indemnified Party to give such notice or any
delay by the Indemnified Party in giving such notice unless, and then only to
the extent that, the rights and remedies of the Indemnifying Party shall have
been prejudiced as a result of the failure to give, or delay in giving, such
notice. Failure by an Indemnifying Party to notify the Indemnified Party of its
election to defend any such claim or action within fourteen (14) business days
of its receipt of notice thereof, shall be deemed to constitute its consent to
assumption by the Indemnified Party of such defense. If the Indemnifying Party
assumes the defense of such claim or litigation resulting therefrom, the
obligations of such Indemnifying Party hereunder as to such claim shall include
taking all steps necessary in the defense or settlement of such claim or
litigation resulting therefrom including the retention of counsel reasonably
satisfactory to the Indemnified Party and holding harmless the Indemnified
Party from and against any and all Damages resulting from, arising out of, or
incurred with respect to any settlement approved by the Indemnifying Party or
any judgment in connection with such claim or litigation resulting therefrom.
No Indemnifying Party shall, in the defense of such claim or litigation, (i)
consent to the entry of any judgment (other than a judgment of dismissal on the
merits without costs) except with the written consent of the Indemnified Party
or (ii) enter into any settlement (except with the written consent of the
Indemnified Party), which does not include as an unconditional term thereof the
giving by the claimant or the plaintiff to the Indemnified





                                     41
<PAGE>   43
Party or parties to be indemnified a release from all liability in respect of
such claim or litigation, unless in either case all Indemnifying Parties shall
jointly and severally agree to hold harmless the Indemnified Party from and
against any and all Damages resulting from, arising out of or incurred with
respect to such judgment or settlement.

         (b) If the Indemnifying Party shall not assume the defense of any such
claim by a third party or litigation resulting therefrom, the Indemnified Party
may defend against such claim or litigation in such manner as it deems
appropriate, and, unless the Indemnifying Party shall deposit with the
Indemnified Party a sum equivalent to the total amount demanded in such claim
or litigation plus an amount equal to the estimate by the Indemnified Party of
the cost of defending the same, the Indemnified Party may settle such claim or
litigation on such terms as it may deem appropriate and the Indemnifying Party
shall promptly reimburse the Indemnified Party for the amount of such
settlement and for all damages incurred by the Indemnified Party in connection
with the defense against or settlement of such claim or litigation.

      The obligation of the Indemnifying Party hereunder is subject to the
Indemnified Party fully cooperating with the Indemnifying Party in its defense
or settlement of any claim for which the Indemnified Party seeks to be
indemnified hereunder, including without limitation, providing all information
and taking all actions reasonably requested by the Indemnifying Party in
connection therewith.

         (c) Any indemnity payable pursuant to this Article VII shall be paid
within the later of (a) thirty (30) days after the Indemnified Party's request
thereof (in the case of claims involving a





                                     42
<PAGE>   44
third party) or (b) ten (10) days prior to the date on which the Damages upon
which the indemnity is based are required to be satisfied by the Indemnified
Party.

      7.03  Period of Indemnity.

            (a) Period of Indemnity Under this Agreement. The indemnity
obligations described in this Article VII with respect to matters arising under
this Agreement shall remain in full force and effect (i) as they relate to
claims asserted by third parties for a period equal to the applicable statute
of limitation for such claim, except in connection with the [      ***
      ], for which the period of indemnity shall be unlimited; provided,
however, that if prior to the expiration of such period any claim for
indemnification has been asserted but not fully determined, such period will be
extended as to such claim until it is finally determined and concluded; and
(ii) as they relate to breaches of representations, warranties and covenants
(other than those contained in Section 3.01(e) and 3.01(l) where the
appropriate period shall be the applicable statute of limitations period for
such claim) shall remain in force for a period of two (2) years following the
First Closing Date with respect to the Assets and the Second Closing Date with
respect to the Second Closing Assets in the case of representations and
warranties and in the case of a covenant, two (2) years from the date that such
covenant has been fully performed or waived by the other party, notwithstanding
any investigation conducted before or after the applicable Closing Date as to
the decision of any party to complete such Closing, provided, however, that if
prior to the expiration of such applicable two (2) year period (or any longer
period as provided above with respect to the representations and warranties set
forth in Section 3.01(e) and 3.01(l) hereof), any claim for breach of any such
representation, warranty, covenant or agreement has





                                       43
<PAGE>   45
been asserted but not fully determined, such period will be extended as to such
claim until it is finally determined or concluded.

         (b)  Period of Indemnity Under the Services Subcontract. With respect
to matters arising under the Services Subcontract, the indemnity obligations
described in this Article VII shall remain in full force and effect:

             (i) as they relate to claims asserted by third parties for a period
equal to the applicable statute of limitation for such claim; provided,
however, that if prior to the expiration of such period any claim for
indemnification has been asserted but not fully determined, such period will be
extended as to such claim until it is finally determined and concluded; and


            (ii) as they relate to breaches of representations, warranties and
covenants in the Services Subcontract shall remain in force for a period of two
(2) years following the date of the termination of the Services Subcontract and
in the case of a covenant, two (2) years from the date that such covenant has
been fully performed or waived by the other party, notwithstanding any
investigation conducted before or after the date hereof as to the decision of
any party to enter into such Services Subcontract, provided, however, that if
prior to the expiration of such applicable two (2) year period, any claim for
breach of any such representation, warranty, covenant or agreement has been
asserted but not fully determined, such period will be extended as to such
claim until it is finally determined or concluded.


         Section 7.04   Set-off; Escrow.

         (a)  In order to satisfy any indemnification obligations of any one
party to any other party to this Agreement, and the Other Agreements, each
party hereto hereby grants to each other such





                                       44
<PAGE>   46
party the right (in addition to collecting by way of indemnification directly
from the Indemnifying Party) of setoff (in the manner provided pursuant to this
Section 7.04) against any amount otherwise due to a party by any other party
pursuant to any agreement between Seller or IRI and Purchaser and/or
Manugistics.  In the event that there is any dispute between the parties
regarding the setoff rights of one party to another, the parties shall promptly
cooperate in good faith for the purpose of resolving such dispute, which
resolution, if achieved, shall be binding upon the parties and not subject to
dispute or review, unless otherwise noted in the document evidencing such
resolution.

         (b)   If (i) the party electing to exercise its setoff rights (the
"Electing Party") shall have failed to give written notice of the relevant
Damages within fourteen (14) business days after assertion of a written claim
by any third party or the discovery of facts upon which the claim is based,
which notice specified in reasonable detail the amount, nature and source of
the Damages and the rights of the party against whom setoff is claimed (the
"Charged Party") are prejudiced by such delay, but not otherwise; or (ii) the
Electing Party shall have failed to respond to reasonable requests of the
Charged Party for information with respect to the relevant claim, or (iii) the
Charged Party shall have denied the claim or, in the case of third party
claims, chosen to contest the claim in legal proceedings which have not yet
been finally resolved, and if the parties do not resolve, within the applicable
time period specified in Section 7.02(c), any dispute they have regarding the
Electing Party's right to exercise its setoff right, then the Electing Party
shall not be entitled to exercise its right of setoff.

         (c)   In the event the Electing Party is not entitled to exercise its
right of setoff as provided in subsection 7.04 (b) above, the Electing Party
shall have the right, instead of making any of such payments in accordance with
any of the agreements between any and all of the parties hereto, to





                                       45
<PAGE>   47
deposit in escrow an amount reasonably necessary to cover the Damages that can
be reasonably expected to result from disputed or contested claims for
indemnification.  Any such deposit into escrow shall be pursuant to a Setoff
Escrow Agreement, substantially in the form of Exhibit 7.04 hereto, with an
escrow agent reasonably satisfactory to Manugistics and IRI.  Any amount which
is not setoff by the Electing Party or deposited into escrow by the Electing
Party in accordance with this Section 7.04 shall be paid in accordance with the
terms of this Agreement and the Other Agreements between Seller or IRI and
Purchaser and/or Manugistics.

         (d)   No setoff by any party hereto shall constitute a waiver by the
Charged Party of its right to contest the validity of the underlying claims for
indemnity of the Electing Party pursuant to this Article VII.

tax liabilities of the Logistics Business for all periods ending on or prior to
the First Closing Date and the Second Closing Date, as applicable, and will
preserve all such information, records and documents until the expiration of
any applicable statutes of limitations or extensions thereof.  Purchaser and
Seller also will make available to each other, as reasonably requested by
Purchaser or Seller, as the case may be, personnel responsible for preparing or
maintaining information, records and documents in connection with tax matters,
and they shall also cooperate with each other in the preparation and filing of
tax returns and refund claims relating to periods ending on or prior to the

Agreement shall, directly or indirectly, make any public comment, statement or

know basis) other than with the express written consent of the other party,
except as required by law or court order, and further subject to Manugistics'
and IRI's legal duty to make appropriate public disclosures under SEC or NASD

with any obligation, covenant, agreement or condition may be waived in writing
by the party entitled to the performance of such obligation, covenant or
agreement or who has the benefit of such condition, but such waiver or failure

condition shall not operate as a waiver of, or estoppel with respect to, any
subsequent or other failure.

      Section 9.11. Further Assurances.  Each of the parties hereto shall
hereafter execute and deliver such further documents and instruments and do
such further acts and things as may be required or useful to carry out the
intent and purpose of this Agreement and as are not inconsistent with the terms
hereof.  Seller and IRI shall use their best efforts to obtain any required
consents not received on or before the First Closing Date as promptly as

taking all actions reasonably requested by the party seeking cooperation.

      Section 9.12. Enforcement.  The parties recognize that the
representations, covenants and warranties set forth in this Agreement are
special and unique and, in the event there is a breach hereof by Seller, IRI,
Purchaser or Manugistics, the non-breaching party will suffer irreparable harm,
the amount of which will be impossible to ascertain and as a result of which
the remedy at law will not be adequate.  Accordingly, except as otherwise
provided in Section 7.01(b) and (d), any party shall be entitled, if it so
elects, to institute and prosecute proceedings in any court of competent
jurisdiction, either at law or in equity, to obtain damages for any breach or
to enforce specific performance of the provisions or to enjoin Seller, IRI,
Purchaser or Manugistics from committing any act in breach of this Agreement.
Except as otherwise provided in Section 7.01(b) and (d), the remedies granted
to each party in this Agreement are cumulative and are in addition to remedies
otherwise available to such party at law or in equity.

      Section 9.13. Severability.  If any term or provision of this Agreement
or the application thereof to any person or circumstance shall, to any extent,
be held invalid or unenforceable by any court of competent jurisdiction, the
remainder of this Agreement or the application of any such term or provision to
persons or circumstances other than those as to which it is held invalid or
unenforceable, shall not be affected thereby, and each term and provision of
this Agreement shall be valid and enforceable to the fullest extent permitted
by law.  If any provision contained in this Agreement shall for any reason be
held to be excessively broad as to duration, scope, activity or subject, it
shall be construed by limiting and reducing it, so as to be valid and
enforceable to the extent compatible with the applicable law or the
determination by a court of competent jurisdiction.
