      1.5 Non-Assignable Assets.

            (a) Notwithstanding the foregoing, if any Seller Contract or other
Purchased Asset is not assignable or transferable (each, a "Non-Assignable
Asset") without the consent of, or waiver by, a third party (each, a "Required
Consent"), either as a result of the provisions thereof or applicable Legal
Requirements, and any such Required Consent is not obtained on or prior to the
Closing Date, this Agreement and the related instruments of transfer shall not
constitute an assignment or transfer of such Non-Assignable Asset, and the
Purchasing Parties or their designee(s) shall not assume the Selling Parties'
rights or obligations under such Non-Assignable Asset (and such Non-Assignable
Asset shall not be included in the Purchased Assets). Instead, without limiting
the Selling Parties' obligations under Section 6.7 or the Purchasing Parties'
rights under Section 9.1, each of the parties hereto shall use commercially
reasonable efforts to obtain all such Required Consents as soon as reasonably
practicable after the Closing Date and thereafter the Selling Parties shall
assign to Purchaser or its designee such Non-Assignable Assets. Following any
such assignment, such assets shall be deemed Purchased Assets for purposes of
this Agreement.

            (b) After the Closing and subject to payment of the Purchase Price
by Purchaser pursuant to Section 2.1, the Selling Parties shall cooperate with
the Purchasing Parties in any reasonable arrangement designed to provide the
Purchasing Parties or their designee(s) with all of the benefits of the
Non-Assignable Assets after the Closing as if the appropriate Required Consents
had been obtained, including by granting subleases or other rights and
establishing arrangements whereby the Purchasing Parties or their designee(s)
shall undertake the work necessary to perform under the Seller Contracts.

                                   ARTICLE 2

any consideration payable or otherwise deliverable pursuant to this Agreement to
any Selling Party such amounts as may be required to be deducted or withheld
therefrom under any provision of federal, state, local or foreign Tax law or
under any other applicable Legal Requirement. To the extent such amounts are
properly deducted or withheld, such amounts shall be treated for all purposes
under this Agreement as having been paid to the person to whom such amounts
would otherwise have been paid.

                                   ARTICLE 4

              REPRESENTATIONS AND WARRANTIES OF THE SELLING PARTIES

      Except as specifically set forth on Schedule 4 (the "Seller Disclosure
Schedule") attached to this Agreement (the parts of which are numbered to
correspond to the individual Section numbers of this Article 4, and which
disclosure schedule shall qualify such referenced section and which shall also
qualify any other representation and warranty to the extent the relevance of
such disclosure to other representations and warranties is clearly apparent from
the actual text of the disclosed exception), Seller hereby represents and
warrants (without limiting any other representations or warranties made by any
of the Selling Parties in this Agreement or any other Transaction Document) to
Purchaser as follows:

      4.1 Organization, Good Standing, Qualification. Each Selling Party is an
entity duly organized, validly existing and in good standing under the Laws of
the jurisdiction of its organization with all requisite power and authority to
own, lease and operate its properties and to carry on its business as now being
conducted and as now proposed to be conducted. Each Selling Party is duly
qualified or licensed to do business and is in good standing as a foreign
corporation in each jurisdiction listed on Schedule 4.1(a) and in each
jurisdiction in which the

                                       9


conduct of its business or the ownership, leasing, holding or use of its
properties makes such qualification necessary, except such other jurisdictions
where the failure to be so qualified or licensed or in good standing could not
reasonably be expected to have a Seller Material Adverse Effect. The copies of
organizational documents (including charter, articles of association and bylaws)
of each of the Selling Parties (the "Seller Organizational Documents"), each as
amended to date, and previously delivered to Purchaser's counsel, are complete
and correct, and no amendments thereto are pending. No Selling Party has
violated its applicable Seller Organizational Documents in any respect material
to the Transaction. Schedule 4.1(b) lists every state or foreign jurisdiction in
which each of the Selling Parties has facilities, maintains an office or has an
Employee. None of the Selling Parties nor any of their predecessors has
conducted any business under or otherwise used for any purpose in any
jurisdiction any fictitious name, assumed name, trade name or other name.

      4.2 Authority of Selling Parties.

            (a) Each of the Selling Parties (to the extent a signatory) has full
right, power and authority to enter into this Agreement and any other
agreements, certificates or documents contemplated thereby or hereby
(collectively, the "Related Agreements", and together with the Agreement, the
"Transaction Documents") and to consummate the Transaction. The execution,
delivery and performance of the Transaction Documents by each of the Selling
Parties has been duly authorized by all necessary action of such Selling Party,
and no other action on the part of such Selling Party is required in connection
therewith. The Transaction Documents constitute, or will when executed and
delivered by such Selling Party constitute, valid and binding obligations of
such Selling Party, enforceable in accordance with their respective terms,
except as such enforceability may be subject to applicable bankruptcy,
reorganization, insolvency, moratorium and similar Laws affecting the
enforcement of creditors' rights generally and by general principles of equity.

            (b) Except as set forth on Schedule 4.2(b), no consent, waiver,
approval, order or authorization of, or registration, declaration or filing
with, or notice to any court, administrative agency or commission or other
international, federal, state, county, local or foreign governmental authority,
instrumentality, agency or commission (each, a "Governmental Entity"), is
required by, or with respect to, the Selling Parties or any of their
Subsidiaries in connection with the execution and delivery of this Agreement and
the Transaction Documents to which such Selling Party is a party or the
consummation of the Transaction.

            (c) Schedule 4.2(c) contains a complete and accurate list of all
Required Consents. Except as set forth on Schedule 4.2(c), the execution,
delivery and performance by each Selling Party of the Agreement and the
Transaction Documents to which such Selling Party is a party, and the
consummation of the Transaction, do not and will not conflict with or violate or
result in the violation of or default under (with or without notice or lapse of
time, or both) or give rise to a right of termination, cancellation,
modification or acceleration of any obligation or loss of any benefit under, or
result in the imposition or creation of any Lien upon any of the properties or
assets (tangible or intangible) under (i) any provision of the charter, by-laws
and any other applicable Seller Organizational Document (as amended to date),
(ii) any Laws, order, writ, judgment, injunction, decree, determination or
arbitration award binding upon or applicable to any Selling Party, and (iii) any
indenture or loan or credit agreement or any other material

                                       10


agreement, contract, instrument, mortgage, Lien, lease, permit, authorization,
whether written or oral, to which any Selling Party is a party or is bound, or
result in the creation or imposition of any Lien on any of the assets or the
property of such Selling Party. Except as set forth on Schedule 4.2(c), the
execution, delivery and performance by each Selling Party of the Agreement and
the Transaction Documents to which such Selling Party is a party, and the
consummation of the Transaction do not and will not cause such Selling Party or
Purchaser to become subject to, or to become liable for the payment of, any
Transfer Taxes (other than Transfer Taxes that would not be Assumed
Liabilities).

      4.3 Subsidiaries. Except for the Entities set forth in Schedule 4.3(a)
(the "Insignia Subsidiaries") and the Joint Venture Interest set forth in
Schedule 4.3(b), none of the Selling Parties owns, directly or indirectly, any
capital stock of or any other equity interest in, or controls, directly or
indirectly, any other Person, and none of the Selling Parties are or have
otherwise been, directly or indirectly, a party to, member of or participant in
any partnership, joint venture or similar business entity. Except as
specifically indicated in Schedule 4.3(c), none of the Insignia Subsidiaries is
material to Seller's business, operations or financial condition. Each Insignia
Subsidiary is duly organized, validly existing and in good standing (to the
extent applicable) under the Laws of its jurisdiction of formation. Each
Insignia Subsidiary has the full corporate power and authority to own, lease and
operate its properties and to carry on its business as now being conducted and
as now proposed to be conducted. Each Insignia Subsidiary is duly qualified or
licensed to do business and is in good standing (to the extent applicable) as a
foreign organization in each jurisdiction listed on Schedule 4.3(d) and in each
jurisdiction in which the conduct of its business or the ownership, leasing,
holding or use of its properties makes such qualification necessary, except such
other jurisdictions where the failure to be so qualified or licensed or in good
standing could not reasonably be expected to have a Seller Material Adverse
Effect.

      4.4 Capitalization.

            (a) All of the outstanding capital stock of, or other ownership
interest in, each Insignia Subsidiary, is owned by Seller, directly or
indirectly, free and clear of any Lien and free of any other limitation or
restriction (including any restriction on the right to vote, sell or otherwise
dispose of such capital stock or other ownership interests). There are no
outstanding (i) securities of any Insignia Subsidiary convertible into or
exchangeable for shares of capital stock or other voting securities or ownership
interests in any Insignia Subsidiary or (ii) options or other rights to acquire
from any Insignia Subsidiary, or obligation on the part of any Insignia
Subsidiary to issue, any capital stock, voting securities or other ownership
interests in, or any securities convertible into or exchangeable for any capital
stock, voting securities or ownership interests in, any Insignia Subsidiary (the
items in clauses (i) and (ii) being referred to collectively as the "Subsidiary
Securities"). There are no outstanding obligations of any Insignia Subsidiary to
repurchase, redeem or otherwise acquire any outstanding Subsidiary Securities.
All of the outstanding share capital of each Insignia Subsidiary has been duly
authorized and is validly issued, fully paid and non-assessable, have been
issued in full compliance with all applicable securities laws and other
applicable Laws, and are free and clear of all Encumbrances.

                                       11


            (b) There is no (i) outstanding preemptive right, subscription,
option, call, warrant or other right to acquire any securities or ownership
interest in any of the Insignia Subsidiaries or any agreement to create any such
obligation; (ii) outstanding security, instrument or obligation that is or may
become convertible into or exchangeable for any securities of any Insignia
Subsidiary; (iii) contract under which any Insignia Subsidiary is or may become
obligated to sell, issue or otherwise dispose of or redeem, purchase or
otherwise acquire any of its securities; or (iv) shareholder agreement, voting
trust or other agreement, arrangement or understanding that may affect the
exercise of voting or any other rights with respect to the capital stock or
ownership interest in any Insignia Subsidiary. There are no declared or accrued
but unpaid dividends with respect to any shares of capital stock of any Insignia
Subsidiary.

            (c) No Seller Options or warrants issued by Seller or any other
Selling Party (the "Seller Warrants") will constitute Assumed Liabilities;
following the Closing Purchaser shall have no Liabilities under the Seller
Option Plans.

      4.5 Seller Financial Statements and Internal Controls.

            (a) Since January 1, 2003, Seller has filed with the Securities and
Exchange Commission (the "SEC") all material forms, registration statements,
prospectuses, reports, schedules and documents (including all exhibits,
post-effective amendments and supplements thereto) (the "Seller SEC Documents")
required to be filed by it under each of the Securities Act of 1933, as amended
(the "Securities Act") and the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), all of which, as amended if applicable, complied in all
material respects as to form with all applicable requirements of the Securities
Act and/or the Exchange Act and the Sarbanes-Oxley Act ("SOX") and the rules and
regulations thereunder. As of their respective dates (taking into account any
amendments or supplements filed prior to the date hereof), the Seller SEC
Documents did not contain any untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading.

            (b) Each of the principal executive officer and principal financial
officer of Seller (or each former principal executive officer of Seller and each
former principal financial officer of Seller, as applicable) has made all
certifications required by Rule 13a-14 or 15d-14 under the Exchange Act or
Sections 302 and 906 of SOX and the rules and regulations of the SEC promulgated
thereunder with respect to the Seller SEC Documents, and the statements
contained in such certifications are true and correct. For purposes of this
Section 4.5(b), "principal executive officer" and "principal financial officer"
shall have the meanings given to such terms in SOX. Neither Seller nor any
Insignia Subsidiary has outstanding, or has arranged any outstanding,
"extensions of credit" to directors or executive officers within the meaning of
Section 402 of SOX.

            (c) The consolidated financial statements of Seller included in the
Seller SEC Documents comply as to form, as of their respective dates of filing
with the SEC, in all material respects with applicable accounting requirements
and the published rules and regulations of the SEC with respect thereto, have
been prepared in accordance with generally accepted accounting principles
effective in the United States ("GAAP") applied on a basis consistent throughout
the periods indicated and consistent with each other (except, in the case of
unaudited statements, as permitted by Form 10-Q or 8-K or the applicable rules
of the SEC) applied on a consistent basis during the periods involved (except as
may be indicated in the notes thereto) and fairly present

                                       12


the consolidated financial position of Seller and its consolidated subsidiaries
as of the dates thereof and the consolidated results of their operations and
cash flows for the periods then ended (subject, in the case of unaudited
statements, to normal year-end audit adjustments which are not material). The
books and records of Seller and the Insignia Subsidiaries are maintained in all
material respects in accordance with GAAP and any other applicable legal and
accounting requirements.

            (d) The consolidated financial statements of Seller as of and for
the year ended December 31, 2006 (collectively, the "Seller Financial
Statements", and the balance sheet included therein at December 31, 2006 being
the "Seller Balance Sheet" and December 31, 2006 being the "Balance Sheet Date")
will comply as to form in all material respects with applicable accounting
requirements and the published rules and regulations of the SEC with respect
thereto, will have been prepared in accordance with GAAP and will fairly present
the consolidated financial position of Seller and its consolidated subsidiaries
as of the Balance Sheet Date and the consolidated results of their operations
and cash flows for the period then ended.

            (e) Neither Seller nor any Insignia Subsidiary is a party to, or has
any commitment to become a party to, any joint venture, off-balance sheet
partnership or any similar contract or arrangement (including any contract or
arrangement relating to any transaction or relationship between or among Seller
and any Insignia Subsidiary, on the one hand, and any unconsolidated Affiliate,
including any structured finance, special purpose or limited purpose entity or
Person, on the other hand or any "off-balance sheet arrangements" (as defined in
Item 303(a) of Regulation S-K)), where the result, purpose or intended effect of
such contract or arrangement is to avoid disclosure of any material transaction
involving, or material liabilities of, Seller or any Insignia Subsidiary in
Seller's or such Insignia Subsidiary's published financial statements or other
of the Seller SEC Documents.

            (f) Seller maintains a system of internal accounting controls
sufficient to provide reasonable assurance that: (i) transactions are executed
in accordance with management's general or specific authorizations; (ii)
transactions are recorded as necessary to permit preparation of financial
statements in conformity with GAAP and to maintain asset accountability; (iii)
access to assets is permitted only in accordance with management's general or
specific authorization; and (iv) the recorded accountability for assets is
compared with the existing assets at reasonable intervals and appropriate action
is taken with respect to any differences.

            (g) Except as otherwise disclosed in the Seller SEC Documents, since
December 31, 2004, Seller has not received from its independent auditors any
oral or written notification of a (x) "reportable condition" or (y) "material
weakness" in Seller's internal controls. For purposes of this Agreement, the
terms "reportable condition" and "material weakness" shall have the meanings
assigned to them in the Statements of Auditing Standards 60, as in effect on the
date hereof.

            (h) To Seller's Knowledge, no current or former Employee has
provided information to any Governmental Entity regarding the commission of any
crime or the violation of any Law applicable to Seller, any Insignia Subsidiary
or any part of their respective operations.

                                       13


            (i) During the periods covered by Seller Financial Statements,
Seller's external auditor was independent of Seller and its management.

            (j) Seller has in place a revenue recognition policy consistent with
GAAP.

      4.6 Liabilities.

            (a) As of the Closing, neither Seller nor any Insignia Subsidiary
will have (i) any liability, indebtedness, obligation, expense, claim,
deficiency, guaranty or endorsement of any type, whether accrued, absolute,
contingent, matured, unmatured or other (whether or not required to be reflected
in Seller Financial Statements in accordance with GAAP), that has not (A) been
reflected or reserved against in the Seller Balance Sheet or (B) arisen in the
ordinary course of Seller's business consistent with past practices since the
Balance Sheet Date, other than Excluded Liabilities not assumed by any
Purchasing Party pursuant to this Agreement or by operation of law, or (ii) any
"off-balance sheet arrangements" (as such term is defined in Item 303(a)(4) of
Regulation S-K promulgated under the Exchange Act).

            (b) Schedule 4.6(b) sets forth an accurate and complete breakdown of
(i) the aging of the accounts payable of Seller and its Subsidiaries as of
December 31, 2006; (ii) any customer deposits or other deposits held by Seller
and its Subsidiaries as of the date hereof; and (iii) all notes payable and
other indebtedness of Seller and its Subsidiaries as of the date hereof.

            (c) As of the Closing all accounts payable of Seller and its
Subsidiaries as of December 31, 2006 will be reflected on the Seller Financial
Statements. All accounts payable of Seller and its Subsidiaries that arose after
December 31, 2006 have been recorded on the accounting books and records of
Seller. All outstanding accounts payable of Seller and its Subsidiaries
represent valid obligations arising from bona fide purchases of assets or
services, which assets or services have been delivered to Seller or its
Subsidiaries.

            (d) Neither Seller nor any Insignia Subsidiary has, at any time, (i)
made a general assignment for the benefit of creditors, (ii) filed, or had filed

            (c) The Real Property Leases are in good standing and are valid,
binding and enforceable in accordance with their respective terms, and there
does not exist under any such Real Property Lease any default by Seller or any
Insignia Subsidiary or, to Seller's Knowledge, by any other Person, or any event
that, with or without notice or lapse of time or both, would constitute a
default by Seller or any Insignia Subsidiary or, to Seller's Knowledge, by any
other Person. Seller has delivered to Purchaser complete copies of all Real
Property Leases, including all amendments and agreements related thereto, and
the Real Property Leases constitute the entire agreement between Seller or any

with respect thereto.

            (b) Seller has complied with all requirements of the United States
and foreign patent offices or applicable Governmental Entities to maintain
Seller Patents, including payment of all required fees to such offices or
agencies. Seller has no Knowledge of any prior art references or prior public

to invalidate Seller Patents or any claim thereof, or of any conduct the result
of which could reasonably be expected to render Seller Patents or any claim
thereof invalid or unenforceable. The original, first and joint inventors of the
subject matter claimed in the patents and patent applications included in Seller

                                       19

solely by Seller or an Insignia Subsidiary free and clear of any Liens, or (ii)
rightfully used and authorized for use by Seller or an Insignia Subsidiary and
their permitted successors pursuant to a valid and enforceable written license.
Each item of Seller Intellectual Property is free and clear of any Encumbrances,

rights in Seller Intellectual Property necessary to carry out Seller's and the
Subsidiaries' former and current activities, including rights to make, use,
exclude others from using, reproduce, modify, adapt, create derivative works
based on, translate, distribute (directly and indirectly), transmit, display and

any of them have breached, violated or defaulted under, any of the terms or
conditions of any license, sublicense or other agreement to which Seller or any
Insignia Subsidiary is a party or is otherwise bound relating to any of Seller
Intellectual Property, nor does Seller have Knowledge of any event or occurrence
that could reasonably be expected to constitute such a breach, violation or
default (with or without the lapse of time, giving of notice or both). Each such
agreement is in full force and effect, and neither Seller nor any Insignia
Subsidiary is in default thereunder, nor to the Knowledge of Seller is any party
obligated to Seller or any Insignia Subsidiary pursuant to any such agreement in
default thereunder. Following the Closing Date, subject to receipt of any
Required Consents, Purchaser will be permitted to exercise all of Seller's
rights under such contracts, licenses and agreements to the same extent Seller
and each Insignia Subsidiary would have been able to had the Transaction not
occurred and without the payment of any additional amounts or consideration
other than fees, royalties or payments which Seller or any Insignia Subsidiary
would otherwise have been required to pay had the Transaction not occurred.

consideration (whether financial or otherwise) to any third party, nor is any
third party otherwise entitled to any consideration, with respect to any
exercise of rights by Seller or any Insignia Subsidiary or Purchaser, as
successor to Seller or any Insignia Subsidiary, in Seller Intellectual Property.

            (e) To the Knowledge of Seller, the use of Seller Intellectual
Property by Seller and the Insignia Subsidiaries, as previously used and as
currently used, has not infringed and does not infringe any other Person's
copyright, trade secret rights, right of privacy, right in personal data, moral
right, patent, trademark, service mark, trade name, firm name, logo, trade
dress, mask work or other intellectual property right, or give rise to any claim
of unfair competition. No funds or facilities of any university were used in the
development of Seller

                                       20

effectiveness or ownership by Seller or any Insignia Subsidiary of any of Seller
Intellectual Property or (ii) to the effect that the use, reproduction,
modification, manufacture, distribution, licensing, sublicensing, sale, or any
other exercise of rights in any Seller Intellectual Property by Seller and its
Subsidiaries or by any licensee of Seller of any Insignia Subsidiary, infringes
or will infringe on any intellectual property or other proprietary or personal
right of any Person have been asserted against Seller or any Insignia Subsidiary
or, to Seller's Knowledge, are threatened by any Person nor, to Seller's
Knowledge, does there exist any valid basis for such a claim. There are no legal
or governmental proceedings, including interference, re-examination, reissue,
opposition, nullity, or cancellation proceedings pending that relate to any of
Seller Intellectual Property owned by Seller, other than review of pending
patent and trademark applications, and neither Seller nor any Insignia
Subsidiary is aware of any information indicating that such proceedings are
threatened or contemplated by any Governmental Entity or any other Person. All

Knowledge, there is no unauthorized use, infringement, or misappropriation of
any Seller Intellectual Property by any third party or Employee.

parties (including current and former Employees) who have created any portion
of, or otherwise have any rights in or to, Seller Intellectual Property owned by
Seller or any of the Insignia Subsidiaries valid and enforceable written
assignments of any such work, invention, improvement or other rights to Seller
and each Insignia Subsidiary and have provided true and complete copies of such
assignments to Purchaser.

            (g) Upon Closing, each item of Seller Intellectual Property will be
owned by Purchaser or will be immediately available for use by Purchaser on
terms and conditions substantially identical to those under which Seller and the
Insignia Subsidiaries presently uses such Seller Intellectual Property, without
any affirmative act by Purchaser or any other Person. Such ownership and right
to use are (and upon Closing, will be) free and clear of any Encumbrances.

            (h) Seller Intellectual Property owned by Seller or any Insignia
Subsidiary is not subject to any source code escrow or similar agreement.

            (i) Seller and the Insignia Subsidiaries have taken commercially
reasonable measures to protect the proprietary nature of Seller Intellectual
Property and to maintain in confidence all Trade Secrets and Confidential
Information owned or used by Seller or any of the Insignia Subsidiaries,
including by having and enforcing a policy requiring all current and former
employees, consultants and contractors of Seller and the Insignia Subsidiaries
to execute appropriate confidentiality and intellectual property assignment
agreements. Seller has no Knowledge of any violation or unauthorized disclosure
of any Trade Secret or Confidential Information related to the Business, the
Purchased Assets or the Assumed Liabilities, or obligations of confidentiality
with respect to such.

            (j) Seller Intellectual Property does not contain any computer code
designed to disrupt, disable or harm in any manner the operation of any software
or hardware. None of Seller Intellectual Property contains any worm, bomb,
backdoor, clock, timer or other disabling

                                       21


device, code, design or routine which causes the software or any portion thereof
to be erased, inoperable or otherwise incapable of being used, either
automatically, with the passage of time or upon command by any party.

            (k) Schedule 4.12(k) lists all licenses, sublicenses and other
agreements pursuant to which Seller is authorized to use any Intellectual
Property of third Persons that is (i) incorporated in or bundled with the Seller
Products or Seller Intellectual Property or (ii) used in connection with, any
Seller Product or Service, or any product or service currently under
development.

            (l) Except as set forth on Schedule 4.12(l), the Seller Intellectual
Property does not include any Publicly Available Software. Neither Seller nor
any of the Insignia Subsidiaries have used Publicly Available Software in whole
or in part in the former, current or currently planned development of any part
of Seller Intellectual Property in a manner that may subject Seller Intellectual
Property owned by Seller, in whole or in part, to all or part of the license
obligations of any Publicly Available Software. To Seller's Knowledge, no source
code licensee of Seller has received from Seller or distributed to any third
party any combination of Publicly Available Software and Seller Intellectual
Property owned by Seller in a manner that may subject Seller Intellectual
Property owned by Seller, in whole or in part, to all or part of the license
obligations of any Publicly Available Software.

professional services agreements with their customers, agreements with
merchants, agreements with outside consultants for the performance of
professional services on the behalf of Seller, the Subsidiaries or any of their
respective customers, nor any agreement or license with any end user or reseller
of Seller's or any Insignia Subsidiary's products, confers upon any Person other

ownership of, or granted any exclusive license with respect to, any Seller
Intellectual Property to any Person.

            (o) Neither Seller nor any of the Insignia Subsidiaries has
participated in any standards setting activities or joined any standards setting
organizations that would affect the proprietary nature of Seller Intellectual
Property owned by Seller or restrict the ability of Seller or any of the
Insignia Subsidiaries to enforce, license, or exclude others from using Seller
Intellectual Property owned by Seller.

            (p) Seller has never agreed to indemnify any Person for or against
any interference, infringement, misappropriation, or other conflict with respect
to any of Seller Intellectual Property or any Intellectual Property that was
formerly Seller Intellectual Property.

            (q) Schedule 4.12(q) contains a list, including names, addresses,
contact names, telephone numbers, termination date and next renewal date, of all
agreements pursuant to which Seller or any Insignia Subsidiary is obligated to
provide support services (such agreements, as supplemented below, are referred
to collectively as the "Support Agreements"). Copies of all Support Agreements
in force on the date of this Agreement have been provided to

                                       22


Purchaser. Neither the Standard Support Agreement nor any other agreement would
obligate the Purchaser after the date of this Agreement to provide any
improvement, enhancement, change in functionality or other alteration to the
performance of any Seller Product or Service, other than error corrections and
upgrades if and when made available to Seller's customers generally. The
versions of the Seller Products currently supported by Seller are set forth on

Seller Product, all applicable contractual commitments and all applicable
express and implied warranties, except for such violations as could not
individually or in the aggregate reasonably be expected to have a Seller
Material Adverse Effect. Neither Seller nor any Insignia Subsidiary has any
liability or obligation for replacement or repair thereof or other damages in
connection therewith except liabilities or obligations for replacement or repair
incurred in the ordinary course of business consistent with past practice. No
Seller Product is subject to any guaranty, warranty, or other indemnity beyond
the applicable standard terms and conditions of sale, license or lease or beyond
that implied or imposed by applicable Law.

            (b) All services provided by Seller or any of the Insignia
Subsidiaries to any third party ("Services") were performed in conformity with
the terms and requirements of all applicable warranties and other Seller

has or has had, directly or indirectly, (i) an economic interest in any Person
which furnished or sold, or furnishes or sells, services or products that Seller
or any Insignia Subsidiary furnishes or sells, or proposes to furnish or sell,
or (ii) an economic interest in any Person that purchases from or sells or
furnishes to, Seller or any Insignia Subsidiary, any goods or services or (iii)
a beneficial interest in any Seller Contract; provided, however, that ownership

corporation shall not be deemed an "economic interest in any entity" for
purposes of this Section 4.16.

            (b) There are no receivables of Seller or any Insignia Subsidiary
owed by any director, officer, current or former Employee, or consultant to
Seller or any Insignia Subsidiary (or any ancestor, sibling, descendant, or

                                       25


corporation in which any of such Persons has an economic interest), other than

to have a Seller Material Adverse Effect. Neither Seller nor any Insignia
Subsidiary has received any written notice from any Governmental Entity or any
other Person regarding any actual, alleged, possible or potential violation of,
or failure to comply with, any Law that has not been cured or resolved. Seller
and each of the Insignia Subsidiaries is in compliance with its stated privacy
policies contained on any websites maintained by or on behalf of Seller or any

suit or proceeding of any nature pending or, to Seller's Knowledge, threatened
against Seller or any of the Insignia Subsidiaries, any of their respective
properties or assets or any of their respective officers, directors or
Employees, nor, to the Knowledge of Seller, is there any reasonable basis
therefor. There is no investigation pending or, to Seller's Knowledge,
threatened against Seller or any of the Insignia Subsidiaries, any of their
respective properties or any of their respective officers, directors or
Employees by or before any Governmental Entity. No Governmental Entity has at
any time challenged or questioned the legal right of Seller or any Insignia

Employees, officers and directors of Seller, any of the Insignia Subsidiaries or
any Affiliate thereof, including the type of coverage, the carrier, the amount

claim by Seller or any of the Insignia Subsidiaries or any Affiliate thereof
pending under any of such policies or bonds as to which coverage has been
questioned, denied or disputed or that Seller has a reason to believe will be
denied or disputed by the underwriters of such policies or bonds. There is no
pending claim that will exceed the policy limits. All premiums due and payable
under all such policies and bonds have been paid (or if installment payments are
due, will be paid if incurred prior to the Closing) and Seller, the Insignia
Subsidiaries and their Affiliates are otherwise in material compliance with the
terms of such policies and bonds. Seller has no Knowledge of a threatened
termination of, or premium increase with respect to, any of such policies. None

self-insurance plan or program.

any way on (A) the performance by such Person of any of his or her duties or
responsibilities for Seller or any Insignia Subsidiary, or (B) Seller's business
or operations; (v) to Seller's Knowledge, no current Employee, contractor or

labor dispute or union organizing activity, or any similar activity or dispute,
affecting Seller, any of the Insignia Subsidiaries or any Employees.

            (h) To the extent applicable, the current and former Employees have
been, and currently are, properly classified under the Fair Labor Standards Act

claims for employment discrimination, harassment, retaliation, unfair labor
practices, grievances, wrongful discharge, breach of contract, tort, unfair

reasonably anticipated claims or actions against Seller or any of the Insignia
Subsidiaries under any workers compensation policy or long-term disability
policy.

each Employee, is in compliance with all applicable visa and work permit
requirements, and no visa or work permit held by an Employee will expire during
the six (6) month period beginning at the date of this Agreement.

            (m) To the Seller's Knowledge, neither the execution, delivery and
performance of the Transaction Documents, nor the carrying on of the Business as
presently conducted or as presently proposed to be conducted, nor any activity
of any officers, directors, Employees or consultants of Seller or a Insignia
Subsidiary in connection with the carrying on of the Business as presently
conducted or as presently proposed to be conducted, will conflict with or result
in a breach of the terms, conditions or provisions of, or constitute a default
under, any contract or agreement under which any of such officers, directors,

by that jurisdiction with respect to the Purchased Assets or the Business. The
Selling Parties have delivered or made available to Purchaser correct and

Responsibility Act of 1982. None of the Purchased Assets directly or indirectly

confidentiality and Intellectual Property Rights, and to transfer all
Governmental Approvals (to the extent transferable) to the Purchaser, (iii)
permit the Purchaser and its Representatives continued access to information
referred to in Section 6.5 that remains under such Selling Party's dominion and
control and (iv) cooperate with reasonable requests from Purchaser to ensure an
orderly transfer of customer relationships involving the Business to Purchaser.
After the Closing, each Selling Party shall promptly deliver to Purchaser (i)
any mail, packages, orders, inquiries and other communications addressed to such
Selling Party and relating to the Business and (ii) any property that such
Selling Party receives and that properly belongs to Purchaser.

      7.3 Reserved.

      7.4 Return of Purchased Assets. If, for any reason after the Closing, any
asset is ultimately determined to be an Excluded Asset, (i) Purchaser shall
transfer and convey (without further consideration) to the appropriate Selling
Party, and such Selling Party shall accept, such asset; (ii) the appropriate
Selling Party shall assume, and agree to pay, perform, fulfill and discharge
(without further consideration) any liabilities associated with such assets; and
(iii) Purchaser and the appropriate Selling Party shall execute such documents
or instruments of conveyance or assumption and take such further acts which are
reasonably necessary or desirable to effect the transfer of such asset back to
the Selling Party.

      7.5 Records and Documents. Following the Closing, Purchaser shall take
possession of those records and documents related to the Business as may be
necessary or useful in connection with Purchaser's conduct of the Business after
the Closing. Purchaser shall use its reasonable efforts to maintain such records
and documents for at least six years after the Closing. At Seller's request,
Purchaser shall provide Seller and its representatives with reasonable access to
such records and documents.

      7.6 Bulk Sales Indemnification. Purchaser hereby waives compliance by each
Selling Party with any applicable bulk sales Legal Requirements in connection
with the Transaction; provided, however, that Seller shall indemnify, defend and
hold harmless Purchaser with respect to any and all Damages related to,
resulting from or arising out of any noncompliance by any Selling Party with
applicable bulk sales Legal Requirements in connection with the Transaction.

      7.7 Noncompetition Agreement.

            (a) Noncompetition. For and in consideration of the Transaction
contemplated herein, during the period commencing with the Closing Date and
ending on the fifth anniversary of the Closing Date (the "Noncompetition
Period"), no Selling Party or any of

                                       41


their Subsidiaries shall engage in any Competitive Activity anywhere in the
world. For purposes of this Agreement, "Competitive Activity" shall mean
directly or indirectly (or having any interest in, or performing any services
for, any Person directly or indirectly) engaging in any activity that is the
same as, or directly competitive with any part of the Business.

            (b) Scope and Choice of Law. It is the understanding of the parties
that the scope of the covenants contained in this Section 7.7, both as to time
and area covered, are necessary to protect the rights of Purchaser and the
goodwill that is a part of the Business of Seller to be acquired by Purchaser.
It is the parties' intention that these covenants be enforced to the greatest
extent (but to no greater extent) in time, area, and degree of participation as
is permitted by the law of that jurisdiction whose law is found to be applicable
to any acts in breach of these covenants. It being the purpose of this Agreement
to govern competition by the Selling Parties, these covenants shall be governed
by and construed according to that law (from among those jurisdictions arguably
applicable to this Agreement and those in which a breach of this Agreement is
alleged to have occurred or to be threatened) which best gives them effect. If
any such covenants or any part of such covenants is held invalid, void or
unenforceable by any court of competent jurisdiction, such invalidity, voidness,
or unenforceability shall in no way render invalid, void, or unenforceable any
other part of them or any separate agreements not declared invalid, void or
unenforceable; and this Agreement shall in such case be construed as if the
invalid, void or unenforceable provisions were omitted.

            (c) Remedy for Breach. The parties agree that Purchaser shall be
entitled to seek injunctive relief against the Selling Parties in the event of
any breach or threatened breach of any of such covenants by the Selling Parties,
in addition to any other relief (including damages) available to Purchaser under
this Agreement.

            (d) Assignment by Purchaser. The parties agree that the covenants of
the Selling Parties not to compete contained in this Section 7.7 may be assigned
by Purchaser to any Person to whom may be transferred all or substantially all
of the assets related to the Business. It is the parties' intention that these
covenants of Seller shall inure to the benefit of any Person that may succeed to
the Business and/or Purchased Assets of Seller (as acquired by Purchaser under
this Agreement) with the same force and effect as if these covenants were made
directly with such successor.

      7.8 Non-Solicitation of Employees. From the date hereof until two years
after the Closing Date, Seller shall not, and shall cause its Subsidiaries not
to, solicit for employment or hire the Transferred Employees or any employee of
the Purchaser or any of its Affiliates employed in any capacity related to the
Business; provided, however, that this Section 7.8 shall not preclude Seller or
any of its Affiliates from soliciting for employment or hiring any such
individual who responds to a general solicitation through a public medium that
is not targeted at the Transferred Employees or any employee of the Purchaser or
any Insignia Subsidiary employed in any capacity related to the Business.

      7.9 Maintenance of Government Approvals. With effect from the Closing
Date, the Purchaser shall be solely responsible for obtaining and maintaining
all governmental approvals regarding the Business (including, without
limitation, the Governmental Approvals), as well as all ongoing regulatory
compliance relating to thereto (including, without limitation, the reporting of
adverse events).

                                       42


      7.10 Enforcement of Contracts. Seller and its Subsidiaries shall enforce
all of their existing contracts and agreements prohibiting or restraining
competition or the solicitation of employees.

                                   ARTICLE 8

                                   EMPLOYEES

      8.1 Transferred Employees.

            (a) On or before the tenth day prior to the Closing, Purchaser or
one of the other Purchasing Parties shall offer employment commencing on the
Closing Date to each person listed on Schedule 8.1(a) (each, a "Prospective
Employee"), except with respect to any Prospective Employee who is an EU
Transferring Employee as noted on Schedule 8.1(a). Except as otherwise set forth
on Schedule 8.1(a), such offers shall provide for compensation and benefits that
are substantially equivalent, taken as a whole, to those provided by Seller and
its Subsidiaries. Purchaser shall provide Seller prompt notice of any such
offers. Seller shall use commercially reasonable efforts to encourage each
Prospective Employee to whom such an offer has been made to accept such offer of
employment and to continue his or her current employment until commencing
employment with Purchaser or a Purchasing Party. Any Prospective Employee who
accepts such an offer of employment pursuant to the terms and conditions of such
offer shall be referred to in this Agreement as a "Transferred Employee". To the
extent a Prospective Employee is an EU Transferring Employee, the provisions of
Section 8.2 shall apply.

            (b) The parties intend that existing contracts of employment of any
of the Prospective Employees (other than EU Transferring Employees) shall not be
assumed by Purchaser as a result of the Transaction, but rather that the
Prospective Employees will be provided new offers of employment.

            (c) Seller shall, and shall take all action necessary to cause each
Prospective Employee who becomes a Transferred Employee or an EU Transferring
Employee to, cease active participation under all Employee Benefit Plans and any
other current or deferred compensation, incentive, fringe benefit or payroll
plan, policy or program maintained by Seller or its Affiliates as of the close
of the calendar month ending on or immediately after the Closing Date, or such
other date as is required pursuant to the relevant Employee Benefit Plan. Seller
shall be solely responsible for all obligations and liabilities for severance or
termination pay, benefits or notice under any plan, program, policy or
applicable law with respect to any employee of Seller or any other Selling Party
(each a "Current Employee") which accrue on or prior to the Closing Date, or
such other date referred to in the immediately preceding sentence, or with
respect to any Current Employee who is not a Transferred Employee or an EU
Transferring Employee which accrue after the Closing Date.

                                       43


            (d) Seller shall retain responsibility for and continue to pay all
expenses and benefits under the Employee Benefit Plans and all medical, dental,
health, hospital, life insurance and disability expenses and benefits with
respect to claims incurred (whether or not reported) on or prior to the Closing
Date by Transferred Employees or EU Transferring Employees and their spouses and
dependents, or incurred at any time by Current Employees and their spouses and
dependents who are not Transferred Employees or EU Transferring Employees. For
purposes of this Agreement, a claim shall be deemed to be incurred on the date
that the event giving rise to such claim occurs.

            (e) Purchaser agrees to assume the accured but unused vacation of
each Transferred Employee and EU Transferred Employee who consents to such
assignment; Seller agrees to pay to each Transferred Employee and EU Transferred
Employee who does not consent to such assumption an amount equal to the value of
the Employee's accrued but unused vacation.

            (f) In order to secure an orderly and effective transition of the
employee benefit arrangements for Transferred Employees and EU Transferring
Employees and their respective beneficiaries and dependents, the Selling Parties
and Purchaser shall cooperate, both before and after the Closing Date, and
subject to applicable law, regarding the exchange information related to the
Transferred Employees and EU Transferring Employees, including employment
records and benefits information.

            (g) Each of the Selling Parties shall, until the Closing Date:

                  (i) perform its obligations (including without limitation in
            respect of emoluments and outgoings) under the contracts of
            employment of such Transferred Employees and EU Transferring
            Employees, subject to the Selling Parties ability to so perform;

                  (ii) not terminate, or give notice to terminate, the contract
            of employment of, nor dismiss, any of the Transferred Employees or
            EU Transferring Employees (other than for cause) without the prior
            written approval of Purchaser, which approval shall not be
            unreasonably withheld;

                  (iii) pay to the Transferred Employees and EU Transferring
            Employees all sums to which they are legally entitled up to and
            including the Closing Date, except to the extent Purchaser does not
            approve any such payments and subject to the Selling Parties ability
            to so pay;

                  (iv) comply in all respects with Legal Requirements requiring
            prior notice by Seller or any Selling Party to the Transferred
            Employees in connection with any aspect of the Transaction (and to
            provide to the Purchaser such information that the Purchaser may
            reasonably request in writing in order to verify such compliance);

                  (v) not replace, deploy or assign any other person to the
            Business or increase the hours spent by any person on the Business
            such as to result in the likelihood of such person being wholly or
            mainly assigned to the Business within the meaning of the EU Codes;

                                       44


                  (vi) not make, propose or permit any changes to the terms,
            conditions or working conditions of any EU Transferring Employees;
            or

                  (vii) introduce any new contractual or customary practice
            concerning the making of any lump sum payment on the termination of
            employment of any EU Transferring Employees.

      8.2 European Union Legislation. To the extent any part of the Business to
be transferred under this Agreement is situated within the territorial scope and
application of the EU Codes, the following terms shall apply:

            (a) Purchaser shall comply and procure compliance with its
obligations as a transferee under the EU Codes in respect of the compulsory

Parties after the Closing Date, to inform and consult (whether prior to or
following Closing) with EU Transferring Employees, their representatives or any
employees of Purchasing Parties in respect of the transfer of the Business under

            (b) Seller shall comply and procure compliance with its obligations
as a transferor under the EU Codes in respect of any requirement of Selling
Parties to inform and consult (whether prior to or following Closing) with EU
Transferring Employees, their representatives or any employees of the Selling
Parties in respect of the transfer of the Business under this Agreement. Seller
shall also use its best efforts to cause the EU Transferring Employees to
consent to employment with the Purchasing Parties.

            (c) Seller warrants that it has fully and accurately disclosed to
the best of its knowledge and belief to Purchaser the employee liability
information which for the purposes of this Agreement means the following in
respect of each EU Transferring Employee: the identity, age, job title, job
description, start date, details of all amounts payable and benefits provided
to, all terms and conditions of employment or engagement (whether contractual or
otherwise), information of any claim, threatened claim or reasonable grounds to
believe that such EU Transferring Employee may bring a claim; any information of

or in respect of such EU Transferring Employee within the last 2 years, and all
policies and procedures relating to their employment.

            (d) Where by reason of the EU Codes an EU Transferring Employee
after the Closing Date is employed by a Purchasing Party on terms and conditions
less favorable than those which would have been offered to a Prospective
Employee pursuant to Section 7.1(b) had

                                       45

employment in accordance with Section 8.1(b).

and does not, create any rights or obligations to or for the benefit of any
Person other than the Purchasing Parties and the Selling Parties, and in
particular creates no rights or obligations to or for the benefit of any Current

benefits to be obtained by any Current Employee, Transferred Employee or EU

            (a) No claims shall be made by any Indemnified Party for

breach or inaccuracy of any of the Fundamental Representations, unless and until
the aggregate amount of Losses for which the Indemnified Parties seek to be
indemnified pursuant to Section 12.2(a) exceed $50,000 (the "Threshold Amount"),
at which time the Indemnified Parties shall be entitled to indemnification for
all such Losses (including all Losses included within the Threshold Amount).
Notwithstanding the preceding sentence, claims arising from any breach or
inaccuracy of any of the Fundamental Representations may be made without regard
to the Threshold Amount.

            (b) In no event shall the liability of Seller with respect to the

            (c) The limitations set forth in this Section 12.3 shall not apply

            (d) The representations, warranties, covenants and obligations of
the Selling Parties, and the rights and remedies that may be exercised by the
Indemnified Parties based on such representations, warranties, covenants and
obligations, will not be limited or affected by any investigation conducted by
Purchaser or any other Purchasing Party or any agent of Purchaser or any other
Purchasing Party with respect to, or any knowledge acquired (or capable of being
acquired) by Purchaser or other Purchasing Party or any agent of any Purchasing
Party at any time, whether before or after the execution and delivery of this
Agreement or the Closing, with respect to, the accuracy or inaccuracy of or
compliance with any such representation, warranty, covenant or obligation. The

                                       51


      12.4 Procedure for Claims Against Holdback Amount.

            (a) Claims. The Holdback Amount shall be available as a
non-exclusive resource to reimburse the Indemnified Parties for any Losses for
which they are entitled to be indemnified pursuant to Section 12.2 (the "Seller
Indemnification Obligations"). Promptly after becoming aware of any Losses for
which they are entitled to be indemnified pursuant to Section 12.2 (but in no
event later than the Holdback Due Date), the Purchaser shall deliver to Seller a
certificate signed by any appropriately authorized officer of Purchaser (a
"Holdback Certificate") (i) stating the aggregate amount of Losses or an
estimate thereof, in each case to the extent known or determinable at such time,
and (ii) specifying in reasonable detail the individual items of such Losses
included in the amount so stated, the date each such item was paid or properly
accrued or arose, and the nature of the misrepresentation, breach or claim to
which such item is related; provided, however, that no delay on the part of the
Purchaser in notifying Seller shall relieve Seller of any liability or
obligations hereunder, except to the extent that the Seller has been materially
prejudiced thereby, and then only to such extent. In the absence of any
objections to such Holdback Certificate as provided in Section 12.4(b) by the
date set forth in Section 12.4(b), Purchaser shall, subject to the other
provisions of this Agreement, be entitled to reduce the Holdback Amount by the
amount of such Losses in satisfaction of the Seller Indemnification Obligations.

            (b) Objection to Holdback Certificate.

                  (i) Seller shall have thirty (30) days after delivery to it of
            a Holdback Certificate to deliver to Purchaser a written response to
            such Holdback Certificate (a "Holdback Response"). If after such
            thirty (30) day period Seller has not delivered a Holdback Response
            to Purchaser or it has delivered a Holdback Response which does not
            dispute any portion of the Holdback Certificate, the reduction of
            the Holdback Amount specified in the Holdback Certificate shall
            become final. If the Holdback Response disputes any claims contained
            in the Holdback Certificate, Seller and Purchaser shall attempt in
            good faith for an additional thirty (30) days to agree upon the
            rights of the respective parties with respect to each of such
            claims. If Seller and Purchaser should so agree, a certificate
            setting forth such agreement shall be prepared and signed by both
            parties and Purchaser shall promptly pay over to Seller any portion
            of the Holdback Amount that it has agreed to pay.

                  (ii) If no such agreement can be reached after good faith
            negotiations, either Purchaser or Seller may, by written notice to
            the other, demand arbitration of the matter, unless the amount of
            the damage or loss is at issue in pending litigation with a third
            party, in which event arbitration shall not be commenced until such
            amount is ascertained or both parties agree to arbitration; and in
            either such event the matter shall be settled by arbitration
            conducted by three (3) arbitrators. Within fifteen (15) days after
            such written notice is sent, Purchaser (on the one hand) and Seller
            (on the other hand) shall each select one arbitrator, and the two
            arbitrators so selected shall select a third arbitrator. The
            decision of the arbitrators as to the validity and amount of any
            claim in the Holdback Certificate shall be binding and conclusive
            upon the parties to this Agreement.

                                       52


                  (iii) Judgment upon any award rendered by the arbitrators may
            be entered in any court having jurisdiction. Any such arbitration
            shall be conducted under the commercial rules then in effect of the
            American Arbitration Association. Any arbitration shall be held in
            County of Los Angeles, California. The non-prevailing party to an
            arbitration shall pay its own expenses, the fees of each arbitrator,
            the administrative fee of the American Arbitration Association, and
            the expenses, including, without limitation, the reasonable
            attorneys' fees and costs, incurred by the prevailing party to the
            arbitration (as determined by the arbitrator).

            (c) Third-Party Claims. Promptly after the assertion by any third
party of any claim against any Indemnified Party (a "Third-Party Claim") that,
in the judgment of such Indemnified Party, may result in the incurrence by such
Indemnified Party of Losses for which such Indemnified Party would be entitled
to indemnification pursuant to this Agreement, such Indemnified Party shall
deliver to Seller a written notice describing in reasonable detail such
Third-Party Claim; provided, however, that no delay on the part of the
Indemnified Party in notifying Seller shall relieve Seller of any liability or
obligations hereunder, except to the extent that the Seller has been materially
prejudiced thereby, and then only to such extent. The Indemnified Party shall
have the right in its sole discretion to conduct the defense of any such
Third-Party Claim; provided, however, that the parties shall reasonably
cooperate with each other in the choice of counsel to defend the Indemnified
Party for claims for which such Indemnified Party would be entitled to
indemnification pursuant to this Agreement, and in the conduct of the defense of
any such Third Party Claim. If any such action or claim is settled with the
prior written consent of the Seller, or if there be a final judgment for the
plaintiff in any such action, the Indemnified Party shall be entitled to
indemnification for the amount of any Loss relating thereto.

      12.5 Purchase Price Adjustment. Seller and Purchaser agree to treat each
indemnification payment pursuant to this Article 12 as an adjustment to the
Purchase Price for all Tax purposes and shall take no position contrary thereto
unless required to do so by any applicable Legal Requirement or pursuant to a
"determination" within the meaning of Section 1313(a) of the Code or an
analogous provision of state, local or foreign law.

                                   ARTICLE 13

                            MISCELLANEOUS PROVISIONS

      13.1 Expenses. Except as expressly provided elsewhere in this Agreement,
whether or not the Transaction is consummated, each party shall pay it own costs

counsel.

      13.2 Interpretation. Whenever the words "include", "includes" or
"including" are used in this Agreement, they shall be deemed, as the context
indicates, to be followed by the words "but (is/are) not limited to".

                                       53


      13.3 Entire Agreement. Except for the Confidentiality Agreement, which
shall survive the execution of this Agreement in accordance with its terms, this
Agreement, including the other documents and agreements specifically referred to
herein, constitutes the entire agreement between and among the parties hereto
with regard to the subject matter hereof, and supersedes all prior agreements

contemplated in this Agreement except as set forth in the Confidentiality
Agreement.

      13.4 Amendment, Waivers and Consents. This Agreement shall not be changed
or modified, in whole or in part, except by supplemental agreement signed by the
parties. Any party may waive compliance by any other party with any of the
covenants or conditions of this Agreement, but no waiver shall be binding unless
executed in writing by the party making the waiver. No waiver of any provision
of this Agreement shall be deemed, or shall constitute, a waiver of any other
provision, whether or not similar, nor shall any waiver constitute a continuing
waiver. Any consent under this Agreement shall be in writing and shall be
effective only to the extent specifically set forth in such writing.

      13.5 Successors and Assigns. This Agreement shall bind and inure to the
benefit of the parties hereto and their respective successors and permitted

hereto.

District Court for the Southern District of California, and, by execution and
delivery of this Agreement, each of the parties to this Agreement accepts the
exclusive jurisdiction of such courts, and irrevocably agrees to be bound by any
judgment rendered thereby in connection with this Agreement. The foregoing
consents to jurisdiction shall not constitute general consents to service of
process in the State of California for any purpose except as provided above and
shall not be deemed to confer rights on any Person other than the parties to
this Agreement. Each of the parties to this Agreement agree that service of any
process, summons, notice or document by U.S. mail to such party's address for
notice hereunder shall be effective service of process for any action, suit or
proceeding in California with respect to any matters for which it has submitted
to jurisdiction pursuant to this Section 13.7(a).

            (b) Each of the parties hereto hereby irrevocably waives its right
to a jury trial in connection with any action, proceeding or claim arising out
of or relating to this Agreement or any transaction contemplated hereby.

                                       54


      13.8 Rules of Construction. The parties acknowledge that each party has
read and negotiated the language used in this Agreement. The parties agree that,
because all parties participated in negotiating and drafting this Agreement, no
