Licensed Back Intellectual Property. Seller will further provide adequate assurances, reasonably
satisfactory to Purchaser, that the Third-Party Maintenance Provider has deleted any Licensed Back
Intellectual Property code from its systems upon the termination or expiration of its relationship
with Seller and, in any event, at the termination or expiration of the AOL Agreement. Seller will
indemnify and hold Purchaser harmless from and against any claims, damages, losses or other
liability incurred by Purchaser, including reasonable legal fees and related expenses, based upon

component of INS Intellectual Property constituting: (1) material Owned Intellectual Property, (2)
material Third Party Intellectual Property, and (3) Registered Intellectual Property.

(b) Ownership and Right to Use. Seller either: (i) owns exclusively the INS
Intellectual Property and has good and valid title to the INS Intellectual Property, free and clear
of any Encumbrance; or (ii) has the necessary and sufficient valid and legally enforceable rights
to use (free and clear of any Encumbrance) the INS Intellectual Property in the conduct of the INS
Business as it is conducted by Seller, pursuant to a license, consent or other agreement identified
in Schedule 4.6(b). Except as identified in Schedule 4.6(b), Seller created all of
the Owned Intellectual Property. To Seller’s Knowledge, there are no facts or circumstances that
would render the INS Intellectual Property or Seller’s rights in or to the INS Intellectual
Property invalid or unenforceable. No Person has any rights in or to any of the Owned Intellectual
Property that would cause a reversion or renewal of rights in favor of that Person or termination
of Seller’s or, following Closing, Purchaser’s rights in or to the Owned Intellectual Property.

(c) Registered Intellectual Property.

(i) The pending trademark applications listed on Schedule 4.6(c) are the only items of
Registered Intellectual Property. The Registered Intellectual Property remains, valid and
subsisting, in good standing, with all application fees, and other amounts due as of the Closing
Date duly paid, and, except as set forth on Schedule 4.6(c), all necessary documents in connection
with the Registered Intellectual Property have been filed, in a timely manner. Except as set forth
on Schedule 4.6(c), all of the Seller’s rights in and to the Registered Intellectual Property are
enforceable. Seller has made available to Purchaser correct and complete copies of written
documentation evidencing ownership and prosecution (if applicable) of each item of Registered
Intellectual Property.

(ii) Seller has not received any notice of any pending actions or opposition with respect to
the Registered Intellectual Property. Schedule 4.6(c) contains a complete and accurate
list of all actions that must be taken within 90 days following the Closing Date relating to the
payment of any taxes, fees or other amounts, or the filing of any documents necessary or
appropriate to maintain any Registered Intellectual Property with the appropriate official office
(e.g., patent or trademark office, or the appropriate governmental or regulatory agency).

(iii) The various software products, documentation and other materials included in the Owned
Intellectual Property that are distributed or made available to third parties directly by Seller
contain appropriate intellectual property rights notices and legends consistent with applicable
laws and the maintenance of Seller’s rights in and to such materials.

(d) No Violations of Rights. Except as listed on Schedule 4.6(d), no party
has, to Seller’s Knowledge, infringed, misappropriated or otherwise used without authorization any
of the Owned Intellectual Property (including any of Seller’s products or services). Immediately
after the Closing, Purchaser will have sole rights to bring actions for infringement or
misappropriation regarding the Owned Intellectual Property. Neither the conduct of the INS
Business nor Seller’s creation, use, license or other exploitation of any INS Intellectual Property
infringes upon or misappropriates the Intellectual Property or other right of any party, and, to
Seller’s Knowledge, there is no basis for such a claim to be made. Except as set forth in
Schedule 4.6(d), Seller has not received any written claim or notice in which any party
alleges that the INS Business, or the INS Intellectual Property has infringed, misappropriated or
used without authorization any Intellectual Property rights of another party, and, to Seller’s
Knowledge, no basis for any such claim or allegation exists.

(e) Licenses and Rights. Seller has not breached or violated any of the agreements
governing use of any Third Party Intellectual Property and, to the Knowledge of Seller, no other
party to those agreements has breached any of those agreements. Schedule 4.6(e) lists all
agreements with ongoing obligations of Seller pursuant to which Seller has licensed or otherwise
granted rights in or to any of the INS Intellectual Property to any third party, including without
limitation any rights to use, market, distribute or otherwise exploit or commercialize any of the
Owned Intellectual Property. Seller has not breached or violated any of those agreements and, to
the Knowledge of Seller, no other party to those agreements has breached any of those agreements.
Except as set forth on Schedule 4.6(e), Seller is not obligated to pay any royalties or other
payments to third parties with respect to the marketing, sale, distribution, manufacture, license
or use of any INS Intellectual Property.

(f) No Harmful Code. Seller takes commercially reasonable steps to assure that, with
respect to the INS Business, all software and data residing on its computer networks or licensed or
otherwise distributed to customers is free of viruses and other disruptive technological means, and
that the INS Intellectual Property does not contain any Harmful Code.

(g) Software. Each of the computer software programs included in the Owned
Intellectual Property, and each of Seller’s commercial products and services included in the INS
Intellectual Property, is functional and operational substantially in accordance with the
applicable specifications and documentation relating to that software. All Seller software,
products and services with respect to the INS Business have been documented in accordance with the
standard practices of Seller. Seller possesses the source and object code versions of all INS
Software that Seller is currently obligated to support and maintain pursuant to the Customer
Contracts, and such source and object code versions are sufficient to enable a reasonably skilled
engineer to modify, maintain, support and repair the INS Software. Seller shall deliver to
Purchaser, upon Closing, (1) the source and object code versions of all such versions of the INS
Software that Seller currently is obligated to support and maintain, and (2) the source code and
object code versions of all prior releases of INS Software that Seller has in its possession that
are not currently supported or maintained by Seller. No source code of the INS Software or of
other software included in the Owned Intellectual Property has been published in any form or
manner, or licensed or distributed, and such source code is not in the public domain. Other than
the US commercial release versions of Seller’s INS Software, Seller has not prepared and has not
authorized any other party to prepare any other versions of Seller’s products and services with
respect to the INS Business for commercial use, except as identified on Schedule 4.6(g).

(h) Government Funding; Open Source Software. No Owned Intellectual Property or
Seller product or service with respect to the INS Business was developed using government or
university funding or facilities; neither was it obtained from any government or university, except
as set forth on Schedule 4.6(h). Seller has not used Open Source Software in the
development of the products and service of the INS Business in a manner that would subject Seller
or any INS Intellectual Property to all or part of the obligations of Open Source Software. Except
as set forth on Schedule 4.6(h), the INS Intellectual Property does not include any Open
Source Software.

(i) Proprietary Information and Confidentiality. Seller has taken appropriate,
commercially reasonable steps to protect and preserve trade secrets and the confidentiality of
other confidential information included in the INS Intellectual Property. Seller has taken the
appropriate steps necessary to comply with any duties of Seller to protect the confidentiality of
information provided by any other Person to Seller in connection with the INS Business. Each
employee (hired on or after February 7, 2001) and each individual contractor (engaged on or after
February 7, 2001) of the INS Business (whether or not currently employed or engaged) contributing
in any material respect to the Owned Intellectual Property or otherwise to Seller’s products and
services has executed a valid and enforceable written agreement (containing no exceptions or
exclusions from the scope of its coverage) irrevocably assigning all of its Intellectual Property
rights in and to the INS Intellectual Property to Seller. In the case of employees, such agreement
is substantially in the form(s) attached as Exhibit H. None of those current or former
employees, consultants or other independent contractors has violated any of those agreements.

(j) Special Agreements and Terms. Seller has separately identified in Schedules
4.6(a), 4.6(b) and 4.6(j) any of the following related to the INS Intellectual Property: (1)
any exclusive rights in or to the INS Intellectual Property granted by or agreed to by Seller, (2)
any “most favored” treatment or similar rights granted by Seller, whether with respect to pricing
or other terms, and (3) any agreement outside the ordinary course of business under which Seller
has offered another party a refund or similar right with respect to amounts paid to Seller in
connection with products or services provided by Seller or its contractors, where such right is
outstanding as of the Closing Date. Except as set forth in Schedule 4.6(j), there are no source
code escrow agreements to which Seller is a party with respect to the source code of the INS
Software, and Seller has not agreed to any other forms of delivery or disclosure of any source code
of the INS Software to a third party or for the benefit of a party other than Seller. Seller has
received no written notice of, and there is not, any legal proceeding, order, agreement or similar
arrangement that prohibits or restricts Seller from carrying on (in a manner substantially
consistent with the conduct of the INS Business as of the Closing Date) the INS Business anywhere
in the world where Seller does, or presently contemplates doing, business.

(k) Effect of Closing. The consummation of the transactions contemplated by this
Agreement shall not cause Seller or Purchaser to be in violation of any license, sublicense,
agreement or instrument relating to the INS Intellectual Property to which Seller is a party or
otherwise bound, nor will the consummation of the transactions contemplated by this Agreement,
cause: (1) the diminution, termination or forfeiture of any INS Intellectual Property or any rights
of Seller (or after Closing, Purchaser) therein or thereto, or the increase of any financial or
burden with respect to any INS Intellectual Property, (2) any party to be entitled to the release
of any source code escrow of any INS Intellectual Property, or (3) there to be a material breach of
an agreement to which Seller is a party in connection with the INS Intellectual Property, or there
to arise any impairment, claim or Encumbrance on the INS Intellectual Property or any rights of
Seller (or after Closing, Purchaser) therein or thereto. Immediately following consummation of the
transactions contemplated by this agreement, Purchaser shall have the same rights in and to the INS
Intellectual Property as Seller had immediately prior to Closing, including valid and marketable
title to all Owned Intellectual Property.

4.7. Compliance with Law, Other Instruments. Seller has not been and is not currently
in violation of any law, order, statute, rule or regulation applicable to the INS Business except
where the violation would not have a Material Adverse Effect on the Seller’s ability to consummate
the transactions contemplated hereby. The execution, delivery and performance of and compliance
with this Agreement have not resulted and will not result in any violation of, or conflict with, or
constitute (with due notice or lapse of time or both) a default (or give rise to any right of
termination, cancellation or acceleration) under, any term of Seller’s charter or bylaws or any
material contract binding on Seller or result in the creation of any mortgage, pledge, lien,
Encumbrance or charge upon any of the Purchased Assets, the INS Intellectual Property or the INS
Business.

4.8. Litigation. Except as set forth on Schedule 4.8, there are no actions, suits,
proceedings or investigations pending (or to the Seller’s Knowledge, threatened) against Seller
with respect to the Purchased Assets or the INS Business before any court or governmental agency.
There are no actions, suits, proceedings or investigations pending (or to the best Seller’s
Knowledge, threatened), including any asking to enjoin or prevent the consummation of the
transactions contemplated by this Agreement, or otherwise claiming that this Agreement, the
transactions contemplated hereby or the consummation thereof are improper.

4.9. Employees and Contractors. A list of all employees employed in the INS Business
(the “INS Business Employees”), including their current salary and payroll deductions and
independent contractors engaged in the INS Business (the “INS Business Contractors”) is attached
hereto as Schedule 4.9. Schedule 4.9 also includes a list of all contracts
pursuant to which INS Business Contractors are engaged (the “Contractor Agreements”). Except as
set forth on Schedule 4.9, no INS Business Employee or INS Business Contractor has any
agreement regarding employment with Seller. Each INS Business Contractor has been properly
characterized in accordance with applicable tax regulations as an independent contractor and is not
an employee. Seller does not have any collective bargaining agreements covering any of the INS
Business Employees nor does Seller have any express or implied contracts or agreements with any
labor union regarding the INS Business Employees, nor has any labor union, to Seller’s Knowledge,
sought to represent any of the INS Business Employees. Except as set forth on Schedule 4.9, Seller
is not a party to or bound by any employment contract, deferred compensation arrangement, bonus
plan, incentive plan, profit sharing plan, retirement agreement or other employee compensation plan
or agreement with respect to the INS Business Employees. None of the INS Business Employees or INS
Business Contractors is in violation of any term of any employment contract or any other agreement
relating to the right of any such individual to be employed or engaged by the INS Business, and
Seller has not received any notice alleging that any such violation has occurred. Seller has not
received any written notice that any INS Business Employee or INS Business Contractor intends to
terminate his/her/its employment or engagement, nor (except as set forth on Schedule 4.9)
does Seller have any present intention to terminate the employment or engagement of any INS
Business Employees or INS Business Contractors. Each employee (hired on or after February 7, 2001)
and each individual contractor (engaged on or after February 7, 2001) of the INS Business (whether
or not currently employed or engaged) has executed an invention assignment and nondisclosure
agreement substantially in the form attached to Schedule 4.9.

4.10. Employee Benefit Plans.

(a) Except as set forth on Schedule 4.10, Seller does not have or otherwise contribute to or
participate in any Benefit Plan (as herein defined) which is for the benefit of the INS Business
Employees.

(b) No action or failure to take an action by Seller, any Affiliate of Seller (including
affiliates by reason of Sections 414(b), 414(c) or 414(m) of the Code (“ERISA Affiliates”)), or any
other Person, and no facts or circumstances exist that, could directly or indirectly subject
Purchaser or any of its affiliates (or any of their employees or directors) to any Liability of any
nature with respect to any pension, profit-sharing, welfare, hospitalization, insurance, bonus,
incentive, perquisite, paid time off, severance, employment or other benefit plan, policy, practice
or agreement relating to the INS Business Employees which is now, or has been at any time,
sponsored, maintained, contributed to, or required to be contributed to by Seller or any of its
Affiliates (including ERISA Affiliates), to which Seller or any of its Affiliates (including ERISA
Affiliates) are a party, or with respect to which Seller or any of its Affiliates (including ERISA
Affiliates) has or could have any Liability of any nature (each such plan, policy, practice or
agreement is referred to herein as a “Benefit Plan”). Neither the Seller nor any ERISA Affiliate
has ever sponsored, maintained, contributed to or had any obligation to contribute to any Benefit
Plan subject to Section 412 of the Code or Title IV of the Employee Retirement Income Security Act
of 1974, as amended. Each Benefit Plan that is intended to be qualified under Section 401(a) of
the Code is so qualified, and Seller has delivered to Purchaser a currently effective IRS
determination or opinion letter covering such plan. No INS Business Employee is employed outside
the United States, and no Benefit Plan that is applicable to the INS Business Employees is subject
to the laws of any foreign jurisdiction.

4.11. Material Contracts.

(a) Except with respect to non-disclosure agreements and confidentiality agreements, none of
which will affect the operation by Buyer of the INS Business from and after the Closing Date or
otherwise be binding on Buyer, Schedule 4.11 sets forth a complete and correct list of each
contract, agreement or commitment with respect to the INS Business:

would reasonably be expected to have a Material Adverse Effect on the operation of the INS

default or event of material default on the part of Seller, or event which, with or without due
notice or lapse of time or both, would reasonably be expected to constitute a material default or
event of material default on the part of Seller or, to the best of Seller’s Knowledge, any other
party thereto. Complete copies of all of the Contracts, including any amendments, supplements,
addenda, side agreements, side letters, modifications or waivers with respect thereto, have been

other party to any such Material Contract has provided written notice, or to the Knowledge of
Seller, oral notice, ,that Seller is in breach of such Material Contract. To the Knowledge of
Seller, there are no existing delays or other factors which (or factors which with notice or the
passage of time) would result in a material breach of any Material Contract.

agreement has been fully performed or until it expires pursuant to its terms or is otherwise

8.2. Seller Indemnification. Subject in all cases to the limitations set forth in
this Section 8, Seller hereby indemnifies Purchaser and its Affiliates and their respective
directors, officers, agents, and employees (each, individually, a “Purchaser Indemnified Party”
and, collectively, the “Purchaser Indemnified Parties”), from and against, and agree to hold each
of them harmless from and against any and all damage, loss, liability and expense (including,
without limitation, reasonable expenses of investigation and reasonable attorneys’ fees and
expenses in connection with any action, suit or proceeding whether involving a third party claim or
a claim solely between the parties hereto) (“Damages”) incurred or suffered by any Purchaser
Indemnified Party arising out of any misrepresentation or breach of warranty or breach of covenant
or agreement made or to be performed by the Seller pursuant to this Agreement; provided, however,
that, except with respect to claims related to breaches of Sections 2.5, 4.5, 4.6, 4.12 and 4.13(a)
as hereinafter provided, (i) the Seller’s maximum liability under this Section 8.2 shall not exceed
$1,745,000, and (ii), Purchaser acknowledges and agrees that the exclusive source of any amounts

terms set forth herein and in the Escrow Agreement. The Escrow Fund may be augmented by Seller
depositing up to $250,000 as provided in Section 9.12. The Escrow Fund (as supplemented by any
additional funds provided under Section 9.12) shall be subject to reduction to satisfy the
indemnification obligations of the Seller under Section 8.2. Claims for Damages by Purchaser that:
(i) are accepted as valid by the Seller; or (ii) are otherwise determined to be valid, shall be
paid by the Escrow Agent to Purchaser from the Escrow Fund pursuant to Section 8.6 (or paid by
Seller to the extent the Escrow Fund does not aggregate $1,745,000).

8.4. Indemnification Period. Except with respect to the representations and
warranties in Sections 4.5, 4.6, 4.12 and 4.13, the “Indemnification Period” shall commence on the
Closing Date and terminate upon the close of business on the date that is eighteen (18) months
following the Closing Date; provided, however, that with respect to a Purchaser Claim, a portion of
the Escrow Fund (as supplemented by any additional funds provided under Section 9.12), which, in
the reasonable judgment of the Purchaser, subject to the objection of the Seller and the final
disposition of the matter, is necessary to satisfy any unsatisfied claims specified in any
Indemnification Certificate theretofore delivered to the Escrow Agent prior to termination of the
Indemnification Period with respect to facts and circumstances existing prior to expiration of the
Indemnification Period, shall remain in the Escrow Fund until such claims have been resolved. Such
retained portion of the Escrow Fund shall be retained only until the claim for indemnification
pursuant to which such portion is being retained is settled or finally determined between Purchaser
and Seller. In the event the Escrow Fund is not funded with an aggregate of $1,745,000, Seller
shall also remain liable for such amount equal to $1,745,000 less the amount actually funded into
the Escrow Account (including any additional funds provided under Section 9.12) (the “Escrow
Shortfall”). The Indemnification Period with respect to any claims with respect to Section 4.6
shall terminate upon the close of business on the date two years following the Closing Date, and
the Indemnification Period with respect to any claims with respect to Sections 2.5, 4.5, 4.12 and
4.13(a) shall terminate 30 days after the expiration of the statute of limitations with respect to
any such claims. Any unsatisfied claims specified in any Indemnification Certificate with respect
to Sections 2.5, 4.5, 4.6, 4.12 and 4.13(a) delivered to Seller prior to termination of the
applicable Indemnification Period shall remain subject to Seller indemnification hereunder until
such claims have been resolved.

8.5. Purchaser Indemnification. Purchaser hereby indemnifies Seller and its
Affiliates and their respective directors, officers, agents, and employees (each, individually, a
“Seller Indemnified Party” and, collectively, the “Seller Indemnified Parties”), from and against,
and agree to hold each of them harmless from and against any and all Damage incurred or suffered by
any Seller Indemnified Party during the Indemnification Period arising out of any misrepresentation
or breach of warranty or breach of covenant or agreement made or to be performed by the Purchaser
pursuant to this Agreement; provided, however, that the Purchaser’s maximum liability under this
Section 8.5 shall not exceed $1,745,000, and no indemnification shall be claimed until Seller
Indemnified Parties have incurred Damages in an aggregate amount greater than $50,000 and
thereafter shall only be entitled to Damages in excess of such $50,000.

8.6. Claims.

(a) Together, “Purchaser Indemnified Parties” and “Seller Indemnified Parties” are herein
referred to as “Indemnified Parties.” The party from whom indemnification is sought shall be
referred to herein as the “Indemnifying Party.”

(b) Upon receipt by the Escrow Agent or by Purchaser on or before the last day of the
applicable Indemnification Period of a certificate signed by any Indemnified Party (an
“Indemnification Certificate”): (a) stating that with respect to the indemnification obligations of
Seller or Purchaser, Damages exist in an aggregate amount greater than $50,000 have been incurred;
and (b) specifying in reasonable detail the individual items of such Damages included in the amount
so stated, the date each such item was paid, or properly accrued or arose, the nature of the
misrepresentation, breach of warranty or claim to which such item is related, the Escrow Agent or
Purchaser shall, subject to the provisions of this Section 8, pay to the Indemnified Party (in the
case of a Purchaser Indemnified Party, such payment being out of the Escrow Fund), as promptly as
practicable, a cash payment equal to the amount of such Damages in excess of $50,000. The Escrow
Agent will not release any portion of the Escrow Fund to any Purchaser Indemnified Party, the
Seller shall not be obligated to fund the Escrow Shortfall (if any), and the Purchaser shall not
pay Damages to any Seller Indemnified Party pursuant to an Indemnification Certificate until the
claim in such Indemnification Certificate has reached final disposition or is uncontested.

8.7. Objections to Claims from Escrow Fund. At the time of delivery of any
Indemnification Certificate to the Escrow Agent, a duplicate copy of such Indemnification
Certificate shall be delivered to the Seller and for a period of twenty (20) calendar days after
such delivery, the Escrow Agent shall make no payment pursuant to Section 8.6 hereof unless the
Escrow Agent shall have received written authorization from the Seller to make such payment. After
the expiration of such twenty (20) calendar day period, the Escrow Agent shall make payment from
the Escrow Fund in accordance with Section 8.6 hereof (and Seller shall fund any Escrow Shortfall),
provided that no such payment may be made if the Seller shall object in a written statement to the
claim made in the Indemnification Certificate, and such statement shall have been delivered to the
Escrow Agent and to the Purchaser prior to the expiration of such twenty (20) day period. In case
the Seller shall object in writing to any claim or claims by the Purchaser Indemnified Party made
in any Indemnification Certificate, the Purchaser Indemnified Party shall have twenty (20) calendar
days from receipt of the Seller’s objections to respond in a written statement to the objection of
the Seller. If after such twenty (20) calendar day period there remains a dispute as to any claim,
the Seller and the Purchaser shall attempt in good faith for ten (10) calendar days thereafter to
agree upon the rights of the respective parties with respect to each of such claims. If the Seller
and Purchaser should so agree, a memorandum setting forth such agreement shall be prepared and
signed by both parties and shall be furnished to the Escrow Agent. The Escrow Agent shall be
entitled to rely on any such memorandum and shall distribute property from the Escrow Fund in
accordance with the terms hereof.

8.8. Objections to Claims against Purchaser. Purchaser shall have twenty (20)
calendar days after receipt of an Indemnification Certificate to object to such Claim by delivering
a written statement of objection to Seller. If Purchaser shall object in writing to any claim or
claims by the Seller Indemnified Party made in any Indemnification Certificate, the Seller
Indemnified Party shall have twenty (20) calendar days from receipt of the Purchaser’s objections
to respond in a written statement to the objection of the Purchaser. If after such twenty (20)
calendar day period there remains a dispute as to any claim, the Seller and the Purchaser shall
attempt in good faith for ten (10) calendar days thereafter to agree upon the rights of the
respective parties with respect to each of such claims. If the Seller and Purchaser should so
agree, a memorandum setting forth such agreement shall be prepared and signed by both parties and
the Purchaser shall pay such Claim in accordance with the terms hereof.

8.9. Calculation of Damages. The amount of any Damages payable under this Section 8
by an Indemnifying Party shall be net of any amounts recovered or recoverable by the Indemnified
Party under applicable insurance policies or from any other Person alleged to be responsible
therefor. If the Indemnified Party receives any amounts under applicable insurance policies, or
from any other Person alleged to be responsible for any Damages, subsequent to an indemnification
payment by the Indemnifying Party, then such Indemnified Party shall promptly reimburse the
Indemnifying Party for any reasonable payment made or expense incurred by such Indemnifying Party
in connection with providing such indemnification payment up to the amount received by the
Indemnified Party, net of any expenses incurred by such Indemnified Party in collecting such
amount.

8.10. Assignment of Claims. If the Indemnified Party receives any payment from an
Indemnifying Party in respect of any Damages pursuant to Section 8.6 and the Indemnified Party
could have recovered all or a part of such Damages from a third party (a “Potential Contributor”)
based on the underlying Claim asserted against the Indemnifying Party, the Indemnified Party shall
assign such of its rights to proceed against the Potential Contributor as are necessary to permit
the Indemnifying Party to recover from the Potential Contributor the amount of such payment.

8.11. Third-Party Claims. In the event an Indemnified Party becomes aware of a
third-party claim which the Indemnified Party believes may result in a demand against an
Indemnifying Party, the Indemnified Party shall promptly notify the Indemnifying Party of such
claim, and the Indemnifying Party shall be entitled, at their expense, to participate in any
defense of such claim. The Indemnified Party shall have the right to settle any such claim;
provided, however, that the Indemnified Party may not effect the settlement of any such claim
without the prior written consent of the Indemnifying Party, which consent shall not be
unreasonably withheld. Following notice of any claim, the Indemnified Party shall notify the
Indemnifying Party of any discussions, negotiations or other material developments affecting such
claim and, to the extent commercially reasonable, permit the Indemnifying Party to participate in
any such discussions or negotiations.

8.12. Exclusive Remedy and No Duplication. Seller and Purchaser hereby acknowledge
and agree that, from and after the Closing, in the absence of fraud or willful misconduct on the
part of the Indemnifying Party or any of its officers, directors, employees and agents in
connection with the negotiation, execution or delivery of this Agreement or the consummation of the
transactions contemplated thereby, their sole monetary remedy with respect to any and all claims
arising in connection with the transactions contemplated by this Agreement shall be pursuant to the
indemnification provisions set forth in this Section 8. Any liability for indemnification
hereunder shall be determined without duplication of recovery by reason of the state of facts
giving rise to such liability constituting a breach of more than one representation, warranty,
covenant or agreement. Notwithstanding the foregoing, none of the limitations of this Section
shall apply to any claims for breach of the obligations in Section 2.5 or the representations and
warranties in Sections 4.5, 4.6, 4.12 and 4.13(a).

8.13. Fraud; Intentional Misrepresentation. Notwithstanding any provision to the
contrary contained in this Agreement, no limitation on liability shall apply to any claim based on
fraud or intentional misrepresentation.

8.14. Exclusion of Damages. NOTWITHSTANDING ANY OTHER PROVISION OF THIS AGREEMENT TO
THE CONTRARY, IN NO EVENT SHALL DAMAGES INCLUDE A PARTY’S INCIDENTAL OR CONSEQUENTIAL DAMAGES OR
SPECIAL OR PUNITIVE DAMAGES TO SUCH PARTY.

8.15. Tax Indemnity. Notwithstanding anything contained in this Agreement, Seller
shall indemnify Purchaser for any and all (i) Taxes arising out of the transactions contemplated by
this Agreement or (ii) any Taxes of the Seller (including such matters identified on Schedule 4.12)
for which the Purchaser or its affiliates become liable with respect to or relating to any periods
ending on or before the date of the acquisition. This Section 8.15 shall not be subject to any
limitations otherwise applicable under Section 8.

Section 9. Other Agreements

9.1. Ordinary Course Operations; Access; Cooperation, Etc. From and after the date of
this Agreement and until the Closing Date (or until this Agreement is otherwise terminated):

(a) Seller shall operate the INS Business in the ordinary course of business generally
consistent with past practice and in compliance with all applicable laws and regulations, provided
that Seller shall not take any of the actions identified in Section 4.13(c) hereof without the
prior written consent of Purchaser. Seller will use all reasonable efforts to keep the INS
Business and the Purchased Assets substantially intact, including its present operations, physical
facilities, working conditions, and relationships with lessors, licensors, suppliers, customers and
employees.

(b) Seller shall provide Purchaser with full access (at all reasonable times and in a manner
so as not to interfere with the normal business operations of the INS Business) to the properties
and personnel relating to the INS Business, and all books, papers and records relating to the
Purchased Assets and the INS Business in order to facilitate the transition of the INS Business and
personnel to Purchaser.

(c) Seller will not, nor will it authorize or permit any of its or its subsidiaries’ officers,
directors, stockholders, employees, Affiliates, attorneys, financial advisors or other agents or
representatives to, directly or indirectly, solicit, initiate, seek, entertain, encourage,
facilitate or support any inquiry, proposal or offer from, furnish any information to, or
participate in any discussions or negotiations with, any other Person or entity regarding any
acquisition of the Purchased Assets or the INS Business. Seller will notify Purchaser promptly,
and in any event within twenty-four (24) hours, after receipt by Seller (or any of its or its
subsidiaries’ officers, directors, stockholders, employees, Affiliates, attorneys, financial
advisors or other agents or representatives) of any proposal for, or inquiry respecting, any such
proposed acquisition from another Person or entity or any request for information in connection
with such a proposal or inquiry, or for access to the properties, books or records of Seller by any
Person or entity that informs or has informed Seller that it is considering making or has made such
a proposal or inquiry. Seller will keep Purchaser informed on an ongoing basis regarding the
status of any such proposal or inquiry.

(d) Seller will use its best efforts to obtain all necessary consents and approvals to
consummate the transactions pursuant to this Agreement, including, without limitation, those listed
on Schedule 4.4(iii).

(e) Seller shall promptly deliver to Purchaser written notice of any event or development of
which Seller is aware that would (i) render any representation or warranty of Seller in this
Agreement inaccurate or incomplete in any material respect, or (ii) constitute or result in a
breach by Seller of, or a failure by Seller to comply with, any agreement or covenant in this
Agreement. No such disclosure by Seller shall be deemed to avoid or cure any such
misrepresentation or breach. Without limiting the foregoing, Seller will provide prompt written
notice to Purchaser of (i) any communication from any third party alleging that the consent of such
third party is or may be required in connection with the transactions contemplated by this
Agreement; (ii) any communication from any Government Entity in connection with the transactions
contemplated by this Agreement; (iii) any event or circumstance that might reasonably be likely to
give rise to a Material Adverse Effect; or (iv) any action, suit, claim, investigation or
proceeding commenced relating to the INS Business that, if pending on the date of this Agreement,
would have been required to have been disclosed pursuant to Section 4.8.

9.2. Covenant Not To Compete.

(a) In consideration of $25,000 paid by Purchaser (included in the Cash Consideration) (the
“Seller Covenant Consideration”), Seller, on behalf of itself and its direct and indirect
subsidiaries, agrees that it will not directly or indirectly (as an investor, advisor, partner,
consultant, licensor or otherwise), for a period commencing on the Closing Date and ending on the
third (3rd) anniversary of the Closing Date:

(i) engage in any business that competes with the INS Business anywhere in the world;

(ii) recruit, solicit or induce, or attempt to induce, any of the INS Business Employees or
the INS Business Contractors to terminate their employment or engagement with, or otherwise cease
their relationship with Purchaser; or

(iii) solicit, divert or take away, or attempt to divert or to take away, the business or
patronage of any of the INS Business clients, customers or accounts, or prospective clients,
customers or accounts, of Purchaser as at the Closing Date (collectively, the activities described
in this Section 9.2(a)(i), (ii), and (iii) being the “Restricted Business”).

(b) Nothing contained in Section 9.2(a) shall prohibit Seller from acquiring the business,
properties, rights and assets of any company partially engaged in the Restricted Business, whether
by asset or stock purchase, merger (or reverse merger), consolidation or otherwise, provided that:
(x) the Restricted Business does not exceed ten percent (10%) of the net revenues or equity of such
company; and (y) the gross revenues of such company from the Restricted Business do not exceed $5
million. Nothing contained herein shall prohibit Seller from being acquired by any Person even if
such Person is engaged in the Restricted Business, whether by asset or stock purchase, merger,
consolidation or otherwise, or in any manner inhibit or limit an acquiring Person or any of its
Affiliates from making any further acquisitions in the Restricted Business after the consummation
of such acquisition.

(c) If any restriction set forth in this covenant not to compete is found by any court of
competent jurisdiction to be unenforceable because it extends for too long a period of time or over
too great a range of activities or in too broad a geographic area, it shall be interpreted to
extend only over the maximum period of time, range of activities or geographic area as to which it
may be enforceable.

(d) The restrictions contained in this covenant not to compete are necessary for the
protection of the INS Business and goodwill of Purchaser and are considered by Seller and Purchaser
to be reasonable for such purpose. Seller expressly acknowledges the value of the consideration
received in connection with this covenant not to compete. Seller agrees that any breach of this
covenant not to compete may cause Purchaser substantial and irrevocable damage and therefore, in
the event of any such breach, in addition to such other remedies which may be available, Purchaser
may seek specific performance and injunctive relief without the requirement of posting a bond and
without the necessity of proving actual economic damages.

9.3. Agreement Regarding Employees and Contractors.

(a) Prior to the Date of Closing, the Purchaser will extend offers of “at-will” employment to
substantially all INS Business Employees on terms and conditions mutually agreed between Purchaser
and each such INS Business Employee. Seller will, at its option, terminate or redeploy, at
Seller’s expense, any INS Business Employees who are not extended an offer of employment by
Purchaser or who do not accept Purchaser’s offer of employment as of the close of business on the
Closing Date. Purchaser will assume selected Seller contracts with INS Business Contractors
identified on Schedule 4.9, and those contracts of INS Business Contractors not assumed by
Purchaser shall be terminated or the contractor redeployed by Seller, at Seller’s expense.
Notwithstanding any provision herein, after the Closing Date, Purchaser shall not be obligated to
continue the employment of any INS Business Employee or any INS Business Contractor hired by
Purchaser (or retained through the assumed contracts) and shall be free and unencumbered to make
all decisions with regard to such continued service as Purchaser sees fit.

(b) For a period of eighteen (18) months from and after the Closing, Seller shall not,
directly or indirectly, for itself or on behalf of any other Person, induce or attempt to induce
any employee of Purchaser in the INS Business to leave his or her employment with the Purchaser.

9.4. Subcontracting of Excluded Contracts. If there is any Customer Contract that is
not assignable to Purchaser on the Closing Date, and such Customer Contract permits Seller to
subcontract its performance to another party, Purchaser and Seller shall enter into a written
agreement (the “Subcontracting Agreement”), in form and substance mutually satisfactory to
Purchaser and Seller and agreed on or prior to the Closing Date, providing for the subcontracting
by Seller to Purchaser of all of Seller’s obligations under such Excluded Contracts, and such other
terms and conditions as shall be necessary or desirable. Under the Subcontracting Agreement,
Purchaser shall indemnify and hold Seller harmless against all liabilities resulting from acts or
omissions of the Purchaser, provided that, Purchaser shall have no liability to Seller if the
liability of Seller was the result of acts or omissions by Seller, its officers, directors,
employees or agents which impaired or otherwise interfered with Purchaser’s ability to perform
under the terms of the Subcontracting Agreement. Purchaser shall use its commercially reasonable
efforts to fulfill the obligations of all such Excluded Contracts pursuant to the Subcontracting
Agreement until all Customer Contracts that are Excluded Contracts have either expired or been
terminated, provided that, no Excluded Contract shall be renewed or extended beyond the expiration
of its then current term unless such contract has been assigned to Purchaser.

9.5. Seller Assistance to Assure Necessary Intellectual Property. If any Third Party
Intellectual Property identified on Schedule 9.4 is required for the continued operation of
the INS Business but cannot be assigned or sublicensed to Purchaser, Seller will use reasonable
best efforts to assist Purchaser in obtaining a separate license to such software directly from the
relevant licensor.

9.6. Requests for Consents. From the date hereof and for a period of ninety (90) days
following the Closing Date, Seller shall use commercially reasonable efforts to obtain consents
from third parties with respect to the assignment to Purchaser of all Excluded Contracts.
Purchaser shall cooperate with Seller in obtaining such consents. The parties acknowledge that
there is no guarantee that Seller will be able to obtain the consents necessary for the assignment
of all the Excluded Contracts, and failure to obtain all the necessary consents shall in no event
be deemed a breach by Seller. Any Excluded Contract that has been assigned to Purchaser shall
cease to be an Excluded Contract and shall be deemed an Assumed Contract.

9.7. Assumption of Future Obligations. Purchaser shall be solely responsible for all
costs, obligations and expenses arising out of, or in any way related to, the operations of the INS
Business from and after the Closing Date, excluding any third-party claim relating to matters
arising out of any Unassumed Liability or Excluded Assets.

9.8. Transitional Use of Seller Trademark. For a period of 180 days following the
Closing Date, Seller hereby grants Purchaser, to the full extent that Sellers possesses such
rights, a fully paid, non-exclusive, worldwide license to use the Seller’s trademarks as currently
utilized in the INS Business (including but not limited to “LIGHTBRIDGE PREPAY IN” and “LIGHTBRIDGE
PREPAY”) for purposes of transitioning the identity of the INS Business and product to the
Purchaser’s identity. If and to the extent that a longer period is required pursuant to the terms
of any Assumed Contract, such license shall be deemed extended as necessary to satisfy the
requirements of such agreements. All rights in and to the trademark LIGHTBRIDGE (“Seller Mark”)
and all goodwill associated therewith shall remain at all times the sole property of Seller, and
all use of the Seller Mark shall inure to the benefit of Seller. Whenever Purchaser uses the
Seller Mark, Purchaser shall clearly indicate Seller’s ownership thereof. At Seller’s request,
Purchaser shall provide Seller with a sample of the advertising, marketing, instructional or other
materials created by Purchaser that uses or displays the Seller Mark for Seller’s review.

9.9. Revision of Exhibits. The parties agree that the Exhibit G (“Assumed
Contracts”) and Schedule 4.5 (“Excluded Assets”) shall be revised on the Closing Date to reflect,
respectively, the actualContracts that Purchaser will assume as of the Closing Date and the actual
excluded assets.

9.10. Certain Taxes. Notwithstanding anything in this Agreement to the contrary, all
transfer, documentary, sales, use, stamp, registration and other such Taxes and fees (including any
penalties and interest) incurred in connection with the transactions contemplated by this Agreement
(collectively, “Transfer Taxes”), shall be borne by the Seller. The Seller will prepare
and file all necessary Tax Returns and other documentation with respect to all such Transfer Taxes
at its own expense and, if required by applicable Law, the Purchaser will join in the execution of
any such Tax Returns and other documentation.

9.11. Source Code Escrow. Within five (5) business days of the Closing Date,
Purchaser shall deposit onto a secure server a copy of the source code for all versions of the INS
Software transferred to Purchaser under this Agreement, in the form that such source code exists on
the Closing Date (“Deposit Materials”). Purchaser shall prohibit any Purchaser employee from
modifying any of the Deposit Materials; however, if Purchaser deems it to be necessary to protect
the integrity of the Deposit Materials, Purchaser may move the Deposit Materials to another secure
server. Subject to the terms of this Agreement, Seller shall have the right to receive relevant
portions of the Deposit Materials upon the receipt by Seller of an Indemnification Certificate
relating to an indemnification obligation of Seller arising from a breach or claimed breach of
Section 4.6 herein. In the event of any release of Deposit Materials to Seller, Seller may
examine, use, and reproduce the Deposit Materials solely internally, and solely to the extent
required for its evaluation, defense and resolution of the indemnification claim by Purchaser. The
obligations of Purchaser set forth in this Section 9.11 shall terminate immediately upon the
expiration of the Indemnification Period applicable to claims with respect to Section 4.6 herein,
provided that if any claim(s) are still unresolved at such time, the obligations of this Section
shall continue until the last such claim is resolved and shall terminate immediately upon the
resolution of the last of such claims.

Seller further acknowledges and agrees that the Deposit Materials are highly sensitive
confidential and trade secret information of Purchaser, and Seller shall secure and protect
confidentiality of the entirety of the Deposit Materials (and any and all other materials or
information disclosed by or on behalf of Purchaser in connection with the Deposit Materials) in
strict confidence for the benefit of Purchaser, in a manner consistent with maintaining Purchaser’s
rights therein and thereto. Seller shall restrict access to and use of the Deposit Materials
solely to its employees and legal advisors having a need to know, and solely to the extent
necessary to fulfilling its indemnification obligations. Seller shall not disclose to any third
party, orally or in writing, any information regarding the code, architecture, sequencing, or
organization of the Deposit Materials, without first securing from the party to whom the disclosure
is to be made, a written agreement (in a form reasonably acceptable to Purchaser) protecting the
confidentiality of the Deposit Materials. Seller shall cease use of the Deposit Materials once the
Deposit Materials are no longer necessary to meet Seller’s indemnification obligations. The
Seller’s obligations under this Section shall survive termination or expiration of this Agreement.

9.12. Funds Held by Radiomovil Dipsa, S.A. deC.V. The sum of $250,000 (the
“Radiomovil Deposit”) is currently held by Radiomovil Dipsa, S.A. deC.V. pursuant to that certain
Assumed Contract known as Contracto de Licencia de Software y Mantenimiento (PrePay Open)/Software
License and Maintenance Agreement (PrePay Open) by and between Lightbridge, Inc. and Radiomovil
Dipsa, S.A. deC.V., dated June 30, 2004 (the “Radiomovil Contract”). Notwithstanding any other
provision of this Agreement, Seller will maintain the Radiomovil Deposit in place from and after
the Closing Date, and title to the Radiomovil Deposit will be retained by Seller. In recognition
of Seller’s funds being held as the Radiomovil Deposit, the Escrow Fund has been reduced hereunder
by $250,000. Seller will maintain the Radiomovil Deposit until the earlier of the termination of
the Radiomovil Contract or June 30, 2007, provided that Seller may negotiate the release of the
Radiomovil Deposit if such release is obtained without causing a breach of the Radiomovil Contract
and without any cost or obligation to Purchaser either to provide an alternative deposit or to
alter any terms of the Radiomovil Contract. If Seller obtains the release of the Radiomovil
Deposit on or before the termination of the Escrow Agreement, Seller will deposit the Radiomovil
Deposit with the Escrow Agent as additional Escrow Funds to be administered in accordance with the
Escrow Agreement and Section 8.

10.9. Termination; Amendments and Waivers.

(a) This Agreement may be terminated

(i) By written agreement of the parties;

(ii) By either party, upon written notice to the other party, if the Closing has not occurred
on or before June 30, 2005, provided that such failure to close is not as a result of a breach of
this Agreement by the party giving notice of termination;

(iii) By either party hereto, upon written notice to the other party, if there occurs a breach
of a representation or warranty or covenant of the other party which is not cured upon thirty (30)
days written notice to such other party; or

permanent injunction or other order of a court or other competent authority of the transaction that

(b) If this Agreement is terminated as permitted by this Section, such termination shall be
without liability of either party (or any stockholder, director, officer, employee, agent,
consultant or representative of such party) to the other parties to this Agreement; provided,
however, that if such termination shall result from the willful (i) failure of a party to fulfill a
condition to the performance of the obligations of another party, (ii) failure to perform a
covenant of this Agreement, or (iii) breach by any party hereto of any representation or warranty
or agreement contained herein, such party shall be fully liable for any and all Losses incurred or
suffered by the other party as a result of such failure or breach. Notwithstanding any provision
to the contrary contained in this Agreement, the provisions of Sections 1 10.7, 10.8, 10.9(b),

EITHER PARTY BE LIABLE TO THE OTHER UNDER ANY THEORY OF LAW OR EQUITY, INCLUDING, WITHOUT
LIMITATION, TORT, CONTRACT OR OTHERWISE, FOR ANY LOSS OF PROFITS OR REVENUES OR FOR ANY INCIDENTAL,
CONSEQUENTIAL, SPECIAL, OR PUNITIVE DAMAGES, HOWEVER CAUSED, EVEN IF THE PARTY HAS BEEN ADVISED OF
THE POSSIBILITY OF SUCH LOSSES OR DAMAGES.

(c) This Agreement may not be amended except by an instrument in writing signed on behalf of
each of the parties hereto.

(d) No delay or omission to exercise any right, power or remedy accruing to any party upon any
breach or default under this Agreement, shall be deemed a waiver of any other breach or default
theretofore or thereafter occurring. Any waiver, consent, or approval of any kind on the part of
any party of any breach or default under this Agreement, or any waiver on the part of any party of
any provisions or conditions of this Agreement, must be in writing and shall be effective only to
the extent specifically set forth in such writing. All remedies, either under this Agreement or by
law or otherwise afforded to any of the parties, shall be cumulative and not alternative. No
waiver by any party of any default, misrepresentation, or breach of warranty or covenant hereunder,
whether intentional or not, shall be deemed to extend to any prior or subsequent default,
misrepresentation, or breach of warranty or covenant hereunder or affect in any way any rights
arising by virtue of any prior or subsequent such occurrence.

10.10. Severability. Any term or provision of this Agreement that is invalid or
unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability
of the remaining terms and provisions hereof or the validity or enforceability of the offending
term or provision in any other situation or in any other jurisdiction.

10.11. Waiver of Jury Trial. Purchaser and Seller hereby expressly waive any right to
a trial by jury in any action or proceeding to enforce or defend any right, power or remedy under
or in connection with this Agreement or under or in connection with any amendment, instrument,
document or agreement delivered or which may in the future be delivered in connection herewith or
arising from any relationship existing in connection with this Agreement, and agree that any such
action shall be tried before a court and not before a jury. The terms and provisions of this
Section 10.11 constitute a material inducement for the parties entering into this Agreement.

10.12. Press Releases. Prior to Closing, neither Purchaser nor Seller shall issue,
publish or disseminate or cause to be issued, published or disseminated any press release or public
communication relating to this Agreement or any of the transactions contemplated herein without the

any trademark, logo, trade name or other intellectual property or otherwise refer to any other

each identify the other in a post-Closing press release and any required securities law filings;
provided, however, that any such press release shall be subject to the prior review and approval of
the other party, which shall not be unreasonably withheld. Notwithstanding the foregoing, nothing

the parties will mutually agree on a press release to be issued at the time of the execution of
this Agreement.
