          The Seller represents and warrants to the Purchaser that, except as
set forth in the Disclosure Schedule prepared by the Seller and delivered to the
Purchaser simultaneously with the execution of this Agreement (the "CMGI
Disclosure Schedule"), the statements contained in this Article II are true and
correct as of the date of this Agreement, except to the extent such
representations and warranties are specifically made as of a particular date (in
which case such representations and warranties will be true and correct as of
such date). The CMGI Disclosure Schedule shall be arranged in sections and
subsections corresponding to the numbered and lettered sections and subsections
contained in this Article II. The disclosures in any section or subsection of
the CMGI Disclosure Schedule shall qualify other sections and subsections in
this Article II only to the extent it is clear from a reading of the disclosure
that such disclosure is applicable to such other sections and subsections. As
used in this Agreement, a "CMGI Material Adverse Effect" shall mean any material
adverse change, event, circumstance or development with respect to, or material
adverse effect on, the business, assets, liabilities, condition (financial or
other), or results of operations of the Seller (other than changes, events,
circumstances or developments that are the result of economic factors affecting
the economy as a whole or that are the result of factors generally affecting the
industry or specific markets in which the Seller competes). For the avoidance of
doubt, the parties agree that the terms "material", "materially" or
"materiality" as used in this Agreement with an initial lower case "m" shall
have their respective customary and ordinary meanings, without regard to the
meaning ascribed to CMGI Material Adverse Effect.

          SECTION 2.1 Power and Authority; Enforceability. The Seller is a
corporation duly organized, validly existing and in good standing under the laws
of its jurisdiction of incorporation. The Seller has all requisite capacity,
power and authority to execute, deliver and perform this Agreement. This
Agreement has been duly executed and delivered and constitutes a valid and
legally binding obligation of the Seller, enforceable against the Seller in
accordance with its terms, except (a) as limited by applicable bankruptcy,
insolvency, reorganization, moratorium, and other laws of general application
affecting enforcement of creditors' rights generally and (b) as limited by laws
relating to the availability of specific performance, injunctive relief, or
other equitable remedies.

          SECTION 2.2 Ownership; Transferability. The Seller is the legal and
beneficial owner of the Shares and the Debt, free and clear of any security
interest, mortgage, pledge, hypothecation, assignment, deposit arrangement,
encumbrance, lien (statutory or otherwise), charge against or interest in
property to secure payment of a debt or performance of an obligation or other
priority or preferential arrangement of any kind or nature whatsoever (each, an
"Encumbrance"), and there are no restrictions on transfer of the Shares or the
Debt to the Purchaser, or at the Purchaser's direction, to Equity and Finance,
respectively, pursuant to the terms of this Agreement. There are no voting
trusts, voting agreements, proxies or other agreements, instruments or
understandings with respect to the voting of the Shares being sold by

                                       3

<PAGE>

the Seller to the Purchaser to which the Seller is a party. Other than this
Agreement, there are no options, warrants, or purchase, subscription, call,
conversion, exchange or other contracts or instruments obligating the Seller to
sell, exchange, or otherwise deliver, or to purchase, acquire or otherwise
receive, securities of the Company.

          SECTION 2.3 Consents and Approvals. Subject to the accuracy of the
representations and warranties made by the Purchaser in Article IV hereof, to
the knowledge of Seller, neither the execution, delivery and performance of this
Agreement by the Seller, nor the consummation by the Seller of any transaction
related hereto will require any consent, approval, order or authorization of,
filing, registration, declaration or taking of any other action with, or notice
to, any person, other than such consents, approvals, filings or actions (a) as
may be required under the Federal securities laws which have or will be made or
(b) which have already been obtained.

          SECTION 2.4 Conflicts. The execution and delivery by the Seller of
this Agreement and any ancillary contracts, agreements or other documents that
are to be entered into in connection with the transactions contemplated hereby
to which it is or will be a party do not, and the consummation of the
transactions contemplated by this Agreement (the "Contemplated Transactions") do
not, (a) conflict with, or result in any violation or breach of any provision of
the certificate of incorporation or by-laws of the Seller, (b) result in any
violation or breach of, or constitute (with or without notice or lapse of time,
or both) a default (or give rise to a right of termination, cancellation or
acceleration of any obligation or loss of any benefit) under any of the terms,
conditions or provisions of any note, bond, mortgage, indenture, lease, contract
or other agreement, instrument or obligation to which the Seller is a party or
by which it or any of its properties or assets may be bound, or (c) conflict or
violate any permit, concession, franchise, license, judgment, order, decree,
statute, law, ordinance, rule or regulation of any government, governmental
instrumentality or court, domestic or foreign, applicable to the Seller or any
of its properties or assets, except in the case of (b) and (c) for any such
conflicts, violations, defaults, terminations, cancellations or accelerations
which would not, individually or in the aggregate, materially and adversely
affect the Shares and the Debt being conveyed by the Seller to the Purchaser, or
at the Purchaser's direction, to Equity and Finance, respectively, hereunder.

          SECTION 2.5 Litigation. There are no actions, suits, proceedings,
orders, investigations or claims pending or, to the knowledge of the Seller,
threatened against or affecting the Seller, at law or in equity, before any
court, arbitration panel, tribunal or governmental commission, bureau, agency or

delaying, the consummation of the transactions contemplated by this Agreement.
The Seller has no actual knowledge of any material actions, suits, proceedings,
orders, investigations or claims pending or threatened against or affecting the
Company, at law or in equity, before any court, arbitration panel, tribunal or
governmental commission, bureau, agency or instrumentality except as publicly
disclosed in the Company's filings with the Securities and Exchange Commission
pursuant to Sections 13, 14 or 15(d) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act").

course of business.

          SECTION 2.7 Company Default. The Seller does not have any actual
knowledge of a default under any agreement or contract between the Seller and
the Company.

                                   ARTICLE III

                 Representations and Warranties of the Purchaser

          The Purchaser represents and warrants to the Seller that, except as
set forth in the Disclosure Schedule prepared by the Purchaser and delivered to
the Seller simultaneously with the execution of this Agreement (the "CBT
Disclosure Schedule"), the statements contained in this Article III are true and
correct as of the date of this Agreement, except to the extent such
representations and warranties are specifically made as of a particular date (in
which case such representations and warranties will be true and correct as of
such date). The CBT Disclosure Schedule shall be arranged in sections and
subsections corresponding to the numbered and lettered sections and subsections
contained in this Article III. The disclosures in any section or subsection of

Article III only to the extent it is clear from a reading of the disclosure that
such disclosure is applicable to such other sections and subsections. As used in
this Agreement, a "CBT Material Adverse Effect" shall mean any material adverse
change, event, circumstance or development with respect to, or material adverse
effect on, the business, assets, liabilities, condition (financial or other), or
results of operations of the Purchaser and the Subsidiaries, taken as a whole
(other than changes, events, circumstances or developments that are the result
of economic factors affecting the economy as a whole or that are the result of
factors generally affecting the industry or specific markets in which the
Purchaser competes). For the avoidance of doubt, the parties agree that the
terms "material", "materially" or "materiality" as used in this Agreement with
an initial lower case "m" shall have their respective customary and ordinary
meanings, without regard to the meaning ascribed to CBT Material Adverse Effect.

          SECTION 3.1 Existence; Power and Authority. The Purchaser is a
corporation duly organized, validly existing and in good standing under the laws
of its jurisdiction of incorporation. The Purchaser has the requisite corporate
power and authority to execute, deliver and perform this Agreement. The
execution, delivery and performance by the Purchaser of this Agreement and the
consummation by it of the transactions contemplated hereby (the "Contemplated
Transactions") have been duly authorized by the Board of Directors of the
Purchaser, and no other corporate action on the part of the Purchaser is
necessary to authorize the execution and delivery by the Purchaser of this
Agreement or the consummation by it of the Contemplated Transactions. No vote
of, or consent by, the holders of any class or series of capital stock issued by
the Purchaser is necessary to authorize the consummation of the

                                       5

Contemplated Transactions. This Agreement has been duly executed and delivered
and, upon execution by the Seller, will constitute a valid and legally binding

with its terms, except (a) as limited by applicable bankruptcy, insolvency,
reorganization, moratorium, and other laws of general application affecting
enforcement of creditors' rights generally and (b) as limited by laws relating

               (i)   contravene, conflict with, or result in a violation of any
provision of the Certificate of Incorporation or bylaws of the Purchaser;

               (ii)  contravene, conflict with, or result in a violation of any

               (e) Except as set forth in Section 3.7 of the CBT Disclosure
Schedule, there is no agreement, written or oral, between the Purchaser and any

rights), registration under the Act, or voting, of the capital stock of the
Purchaser.

               SECTION 3.8  Subsidiaries.

               (a) Section 3.8 of the CBT Disclosure Schedule sets forth: (i)
the name of each Subsidiary; (ii) the number and type of outstanding equity
securities of each Subsidiary and a list of the holders thereof; (iii) the
jurisdiction of organization of each Subsidiary; (iv) the names of the officers
and directors of each Subsidiary; and (v) the jurisdictions in which each
Subsidiary is qualified or holds licenses to do business as a foreign
corporation or other entity.

               (b) Each Subsidiary is a corporation duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
incorporation. Each Subsidiary is duly qualified to conduct business and is in
good standing under the laws of each jurisdiction in which the nature of its
businesses or the ownership or leasing of its properties requires such
qualification, except where the failure to be so qualified or in good standing,
individually or in the aggregate, has not had and would not reasonably be
expected to have a CBT Material Adverse Effect. Each Subsidiary has all
requisite power and authority to carry on the businesses in which it is engaged
and to own and use the properties owned and used by it. No Subsidiary is in
default under or in violation of any provision of its charter or by-laws. All of
the issued and outstanding shares of capital stock of each Subsidiary are duly
authorized, validly issued, fully paid and nonassessable. All shares of each
Subsidiary that are held of record or owned beneficially by either the Purchaser
or any Subsidiary are held or owned free and clear of any restrictions on
transfer (other than restrictions under the Act and state securities laws),
claims, Encumbrances, options, warrants, rights, contracts, calls, commitments,
equities and demands. There are no outstanding or authorized options, warrants,
rights, agreements or commitments to which the Purchaser or any Subsidiary is a
party or which are binding on any of them providing for the issuance,
disposition or acquisition of any capital stock of any Subsidiary. There are no
outstanding stock appreciation, phantom stock or similar rights with respect to
any Subsidiary. There are no voting trusts, proxies or other agreements or
understandings with respect to the voting of any capital stock of any
Subsidiary.

               (c) The Purchaser does not control directly or indirectly or have
any direct or indirect equity participation or similar interest in any
corporation, partnership, limited liability company, joint venture, trust or
other business association or entity which is not a Subsidiary.

               (d) "Subsidiary" shall mean any corporation, partnership, trust,
limited liability company or other non-corporate business enterprise in which
the Purchaser (or another Subsidiary) holds stock or other ownership interests
representing (a) more than 50% of the voting power of all outstanding stock or
ownership interests of such entity or (b) the right to receive more than 50% of
the net assets of such entity available for distribution to the holders of
outstanding stock or ownership interests upon a liquidation or dissolution of
such entity.

               SECTION 3.9  Financial Statements. Section 3.9 of the CBT
Disclosure Schedule contains: (a) unaudited consolidated balance sheets of the
Purchaser and the Subsidiaries as at December 31, 2001 and the related unaudited
consolidated statements of income, changes in stockholders' equity, and cash
flow for the fiscal year then ended, and (b) an unaudited consolidated balance
sheet of the Purchaser and the Subsidiaries as at June 30, 2002 (the "Interim
Balance Sheet") and the related unaudited consolidated statements of income,
changes in stockholders' equity, and cash flow for the six months then ended,
including in each case the notes thereto. Such financial statements and notes
fairly present the financial condition and the results of operations, changes in
stockholders' equity, and cash flow of the Purchaser and the Subsidiaries as at
the respective dates of and for the periods referred to in such financial
statements, all in accordance with GAAP, subject, in the case of interim
financial statements, to normal recurring year-end adjustments (the effect of
which will not, individually or in the aggregate, be materially adverse) and the
absence of notes (that, if presented, would not differ materially from those
included in the Interim Balance Sheet); the financial statements referred to in
this Section 3.9 reflect the consistent application of such accounting
principles throughout the periods involved. No financial statements of any
person other than the Purchaser and the Subsidiaries are required by GAAP to be
included in the consolidated financial statements of the Purchaser.

               SECTION 3.10 Books and Records. The books of account, minute
books, stock record books, and other records of the Purchaser and the
Subsidiaries are complete and correct. The minute books of the Purchaser and the
Subsidiaries contain accurate and complete records of all meetings held of, and
corporate action taken by, the stockholders, the Boards of Directors, and
committees of the Boards of Directors of the Purchaser and the Subsidiaries, and
no meeting of any such stockholders, Board of Directors, or committee has been
held for which minutes have not been prepared and are not contained in such
minute books.

               SECTION 3.11 Title to Properties; Encumbrances. Section 3.11 of
the CBT Disclosure Schedule contains a complete and accurate list of all real
property, leaseholds, or other interests therein owned by the Purchaser and the
Subsidiaries. The Purchaser and the Subsidiaries own (with good and marketable
title in the case of real property, subject only to the matters permitted by the
following sentence) all the properties and assets (whether real, personal, or
mixed and whether tangible or intangible) that they purport to own, including
all of the properties and assets reflected in the Interim Balance Sheet (except
for assets held under capitalized leases disclosed to the Seller and personal
property sold since the date of the Interim Balance Sheet, as the case may be,
in the ordinary course of business), and all of the properties and assets
purchased or otherwise acquired by the Purchaser and the Subsidiaries since the
date of the Interim Balance Sheet (except for personal property acquired and
sold since the date of the Interim Balance Sheet in the ordinary course of
business and consistent with past practice). All material properties and assets
reflected in the Balance Sheet and the Interim Balance Sheet are free and clear
of all Encumbrances and are not, in the case of real property, subject to any
rights of way, building use restrictions, exceptions, variances, reservations,
or limitations of any nature except, with respect to all such properties and
assets, (a) mortgages or security interests shown on the Interim Balance Sheet
as securing specified liabilities or obligations, with respect to which no
default (or event that, with notice or lapse of time or both, would constitute a
default) exists, (b)

                                       9

mortgages or security interests incurred in connection with the purchase of
property or assets after the date of the Interim Balance Sheet (such mortgages
and security interests being limited to the property or assets so acquired),
with respect to which no default (or event that, with notice or lapse of time or
both, would constitute a default) exists, (c) liens for current taxes not yet
due, and (d) with respect to real property, (i) minor imperfections of title, if
any, none of which is substantial in amount, materially detracts from the value
or impairs the use of the property subject thereto, or impairs the operations of
the Purchaser or the Subsidiaries, and (ii) zoning laws and other land use
restrictions that do not impair the present or anticipated use of the property
subject thereto.

               SECTION 3.12 Absence of Certain Changes. Since June 30, 2002,
there has occurred no event or development which, individually or in the
aggregate, has had, or could reasonably be expected to have in the future, a CBT
Material Adverse Effect.

               SECTION 3.13 Undisclosed Liabilities. Neither the Purchaser nor
the Subsidiaries has any liability (whether known or unknown, whether absolute
or contingent, whether liquidated or unliquidated and whether due or to become
due), except for (a) liabilities shown on the Interim Balance Sheet, (b)
liabilities which have arisen since June 30, 2002 in the ordinary course of
business, (c) contractual and other liabilities that would not reasonably be
required by GAAP to be reflected on a balance sheet and (d) liabilities incurred
after June 30, 2002 in the ordinary course of business and which are not
material in amount.

               SECTION 3.14 Tax Matters.

               (a) Each of the Purchaser and the Subsidiaries has filed on a
timely basis all Tax Returns that it was required to file, and all such Tax
Returns were complete and accurate and disclose all Taxes required to be paid by
the Purchaser and each Subsidiary. Neither the Purchaser nor any Subsidiary is
or has ever been a member of a group of corporations with which it has filed (or
been required to file) consolidated, combined or unitary Tax Returns, other than
a group of which only the Purchaser and the Subsidiaries are or were members.
Each Affiliated Group has filed all Tax Returns that it was required to file
with respect to any Affiliated Period, and all such Tax Returns were complete
and accurate and disclose all Taxes required to be paid by the Purchaser and
each Subsidiary. Each of the Purchaser and the Subsidiaries has paid on a timely
basis all Taxes that were due and payable and each member of an Affiliated Group
has paid all Taxes that were due and payable with respect to all Affiliated
Periods. The unpaid Taxes of the Purchaser and the Subsidiaries for tax periods
through June 30, 2002 do not exceed the accruals and reserves for Taxes
(excluding accruals and reserves for deferred Taxes established to reflect
timing differences between book and Tax income) set forth on the Interim Balance
Sheet. Neither the Purchaser nor any Subsidiary has any actual or potential
liability for any Tax obligation of any taxpayer (including any affiliated group
of corporations or other entities that included the Purchaser or any Subsidiary
during a prior period) other than the Purchaser and the Subsidiaries. All Taxes
that the Purchaser or any Subsidiary is or was required by law to withhold or
collect have been duly withheld or collected and, to the extent required, have
been paid to the proper Governmental Entity. All Taxes (whether or not shown on
any Tax Return) owed by any of the Purchaser and any Affiliated Group have been
timely paid.

                                       10

<PAGE>

               (b) All deficiencies assessed against the Purchaser, any
Subsidiary or any Affiliated Group have been paid in full. The federal income
Tax Returns of the Purchaser and each Subsidiary and each member of an
Affiliated Group have been audited by the Internal Revenue Service or are closed
by the applicable statute of limitations for all taxable years through the
taxable year specified in Section 3.9(b) of the CBT Disclosure Schedule. No
examination or audit of any Tax Return of the Purchaser or any Subsidiary or any
member of an Affiliated Group with respect to an Affiliated Period by any
Governmental Entity is currently in progress or, to the knowledge of the
Purchaser, threatened or contemplated. Neither the Purchaser nor any Subsidiary
nor any member of an Affiliated Group has been informed by any jurisdiction that
the jurisdiction believes that the Purchaser or any Subsidiary or any member of
an Affiliated Group was required to file any Tax Return that was not filed.
Neither the Purchaser nor any Subsidiary nor any member of an Affiliated Group
has waived any statute of limitations with respect to Taxes or agreed to an
extension of time with respect to a Tax assessment or deficiency.

               (c) Neither the Purchaser nor any Subsidiary: (i) is a
"consenting corporation" within the meaning of Section 341(f) of the Internal
Revenue Code of 1986, as amended (the "Code"), and none of the assets of the
Purchaser or the Subsidiaries are subject to an election under Section 341(f) of
the Code; (ii) has been a United States real property holding corporation within
the meaning of Section 897(c)(2) of the Code during the applicable period
specified in Section 897(c)(l)(A)(ii) of the Code; or (iii) has any actual or
potential liability for any Taxes of any person (other than the Purchaser and
its Subsidiaries) under Treasury Regulation Section 1.1502-6 (or any similar
provision of federal, state, local, or foreign law), or as a transferee or
successor, by contract, or otherwise.

               (d) None of the assets of the Purchaser or any Subsidiary: (i) is
"tax-exempt use property" within the meaning of Section 168(h) of the Code; or
(ii) directly or indirectly secures any debt the interest on which is tax exempt
under Section 103(a) of the Code.

               (e) Neither the Purchaser nor any Subsidiary has undergone a
change in its method of accounting resulting in an adjustment to its taxable
income pursuant to Section 481 of the Code.

               (f) Except as set forth on Section 3.14 of the CBT Disclosure
Schedule, as a direct or indirect result of the transactions contemplated by
this Agreement, no payment or other benefit by the Purchaser, and no
acceleration of the vesting of any options, payments or other benefits by the
Purchaser will be (or under Section 280G of the Code and the Treasury
Regulations thereunder be presumed to be) a "parachute payment" to a
"disqualified individual" as those terms are defined in Section 280G of the Code
and the Treasury Regulations thereunder, without regard to whether such payment
or acceleration is reasonable compensation for personal services performed or to
be performed in the future.

knowledge, nor, to the knowledge of the Purchaser, any other party, is in breach
or violation of, or default under, any such Lease, and no event has occurred, is
pending or, to the knowledge of the Purchaser, is threatened, which, after the
giving of notice, with lapse of time, or otherwise, would constitute a breach or

Purchaser, any other party under such Lease;

Customer Deliverables.

Purchaser or a Subsidiary, and the license or agreement pursuant to which the

by the Purchaser and the Subsidiaries in fulfilling their obligations under
their guaranty, warranty, right of return and indemnity provisions during the
fiscal year and the interim period covered by the Financial Statements; and the

each Subsidiary, each ERISA Affiliate and each CBT Plan are in compliance in all
material respects with the currently applicable provisions of ERISA and the Code
and the regulations thereunder (including Section 4980 B of the Code, Subtitle
K, Chapter 100 of the Code and Sections 601 through 608 and Section 701 et seq.
of ERISA). All filings and reports as to each CBT Plan required to have been
submitted to the Internal Revenue Service or to the United States Department of
Labor have been duly submitted. No CBT Plan has assets that include securities
issued by the Purchaser or any ERISA Affiliate.

               (c) There are no Legal Proceedings (except claims for benefits
payable in the normal operation of the CBT Plans and proceedings with respect to
qualified domestic relations orders) against or involving any CBT Plan or
asserting any rights or claims to benefits under any CBT Plan that could give
rise to any material liability.

               (d) All the CBT Plans that are intended to be qualified under
Section 401(a) of the Code have received determination letters from the Internal
Revenue Service to the effect that such CBT Plans are qualified and the plans
and the trusts related thereto are exempt from federal income taxes under
Sections 401(a) and 501(a), respectively, of the Code, no such determination
letter has been revoked and revocation has not been threatened, and no such CBT
Plan has been amended since the date of its most recent determination letter or
application therefor in any respect, and no act or omission has occurred, that
would adversely affect its qualification or

                                       19

Affiliate been obligated to contribute to any "multiemployer plan" (as defined

limited to retiree health coverage and deferred compensation, but excluding
continuation of health coverage required to be continued under Section 4980B of
the Code or other applicable law and insurance conversion privileges under state
law. The assets of each CBT Plan which is funded are reported at their fair
market value on the books and records of such CBT Plan.

          (h)  No act or omission has occurred and no condition exists with
respect to any CBT Plan that would subject the Purchaser, any Subsidiary or any
ERISA Affiliate to (i) any material fine, penalty, tax or liability of any kind
imposed under ERISA or the Code or (ii) any contractual indemnification or
contribution obligation protecting any fiduciary, insurer or service provider
with respect to any CBT Plan.

          (i)  No CBT Plan is funded by, associated with or related to a
"voluntary employee's beneficiary association" within the meaning of Section
501(c)(9) of the Code.

          (j)  Each CBT Plan is amendable and terminable unilaterally by the
Purchaser at any time without liability or expense to the Purchaser or such CBT
Plan as a result thereof (other than for benefits accrued through the date of
termination or amendment and reasonable administrative expenses related thereto)
and no CBT Plan, plan documentation or agreement, summary plan description or
other written communication distributed generally to employees by its terms
prohibits the Purchaser from amending or terminating any such CBT Plan.

     (a) any breach, as of the date of this Agreement or as of the Closing Date,
of any representation or warranty of the Seller contained in this Agreement or
any other agreement or instrument furnished by the Seller to the Purchaser
pursuant to this Agreement;

     (b) any failure to perform any covenant or agreement of the Seller in this
Agreement or any agreement or instrument furnished by the Seller to the
Purchaser pursuant to this Agreement.

     SECTION 6.2 Indemnification Claims.

     (a) The Purchaser shall give written notification to the Seller of the
commencement of any third party action ("Third Party Action"). Such notification
shall be given within 20 days after receipt by the Purchaser of written notice
of such Third Party Action, and shall describe in reasonable detail (to the
extent known by the Purchaser) the facts constituting the basis for such Third
Party Action and the amount of the claimed damages; provided, however, that no
delay or failure on the part of the Purchaser in so notifying the Seller shall
relieve the Seller of any liability or obligation hereunder except to the extent
of any damage or liability caused by or arising out of such failure. Within 20
days after delivery of such notification, the Seller may, upon written notice
thereof to the Purchaser, assume control of the defense of such Third Party
Action with counsel reasonably satisfactory to the Purchaser; provided that (i)
the Seller may only assume control of such defense if (A) it acknowledges in

                                       28

<PAGE>

writing to the Purchaser that any damages, fines, costs or other liabilities
that may be assessed against the Purchaser in connection with such Third Party
Action constitute Damages for which the Purchaser shall be indemnified pursuant
to this Article VI and (B) the ad damnum is less than or equal to the amount of
Damages for which the Seller is liable under this Article VI and (ii) the Seller
may not assume control of the defense of Third Party Action involving criminal
liability or in which equitable relief is sought against the Purchaser. If the
Seller does not, or is not permitted under the terms hereof to, so assume
control of the defense of a Third Party Action, the Purchaser shall control such
defense. The non-controlling party may participate in such defense at its own
expense. The controlling party shall keep the non-controlling party advised of
the status of such Third Party Action and the defense thereof and shall consider
in good faith recommendations made by the non-controlling party with respect
thereto. The non-controlling party shall furnish the controlling party with such
information as it may have with respect to such Third Party Action (including
copies of any summons, complaint or other pleading which may have been served on
such party and any written claim, demand, invoice, billing or other document
evidencing or asserting the same) and shall otherwise cooperate with and assist
the controlling party in the defense of such Third Party Action. The fees and
expenses of counsel to the Purchaser with respect to a Third Party Action shall
be considered Damages for purposes of this Agreement if (i) the Purchaser
controls the defense of such Third Party Action pursuant to the terms of this
Section 6.2(a) or (ii) the Seller assumes control of such defense and the
Purchaser reasonably concludes that the Seller and the Purchaser have
conflicting interests or different defenses available with respect to such Third
Party Action. The Seller shall not agree to any settlement of, or the entry of
any judgment arising from, any Third Party Action without the prior written
consent of the Purchaser, which shall not be unreasonably withheld, conditioned
or delayed; provided that the consent of the Purchaser shall not be required if
the Seller agrees in writing to pay any amounts payable pursuant to such
settlement or judgment and such settlement or judgment includes a complete
release of the Purchaser from further liability and has no other adverse effect
on the Purchaser. The Purchaser shall not agree to any settlement of, or the
entry of any judgment arising from, any such Third Party Action without the
prior written consent of the Seller, which shall not be unreasonably withheld,
conditioned or delayed.

     (b) In order to seek indemnification under this Article VI, the Purchaser
shall deliver a Claim Notice to the Seller.

     (c) Within 20 days after delivery of a Claim Notice, the Seller shall
deliver to the Purchaser a Response, in which the Seller shall: (i) agree that
the Purchaser is entitled to receive all of the Claimed Amount (in which case
the Response shall be accompanied by a payment by the Seller to the Purchaser of
the Claimed Amount, by check or by wire transfer, (ii) agree that the Purchaser
is entitled to receive the agreed amount (in which case the Response shall be
accompanied by a payment by the Seller to the Purchaser of the agreed amount, by
check or by wire transfer or (iii) dispute that the Purchaser is entitled to
receive any of the Claimed Amount.

     (d) During the 30-day period following the delivery of a Response that
reflects a Dispute, the Seller and the Purchaser shall use good faith efforts to
resolve the Dispute. If the Dispute is not resolved within such 30-day period,
the Seller and the Purchaser shall discuss in

                                       29

<PAGE>

good faith the submission of the Dispute to binding arbitration, and if the
Seller and the Purchaser agree in writing to submit the Dispute to such
arbitration, then the provisions of Section 6.2(e) shall become effective with
respect to such Dispute. The provisions of this Section 6.2(d) shall not
obligate the Seller and the Purchaser to submit to arbitration or any other
alternative dispute resolution procedure with respect to any Dispute, and in the
absence of an agreement by the Seller and the Purchaser to arbitrate a Dispute,
such Dispute shall be resolved in a state or federal court sitting in the State
of New York, in accordance with Section 7.12.

     (e)  If, as set forth in Section 6.2(d), the Purchaser and the Seller agree
to submit any Dispute to binding arbitration, the arbitration shall be conducted
by a single arbitrator (the "Arbitrator") in accordance with the Commercial
Rules in effect from time to time and the following provisions:

          (i)   In the event of any conflict between the Commercial Rules in
effect from time to time and the provisions of this Agreement, the provisions of
this Agreement shall prevail and be controlling.

          (ii)  The parties shall commence the arbitration by jointly filing a
written submission with the New York, New York office of the AAA in accordance
with Commercial Rule 5 (or any successor provision).

          (iii) No depositions or other discovery shall be conducted in
connection with the arbitration.

          (iv)  Not later than 30 days after the conclusion of the arbitration
hearing, the Arbitrator shall prepare and distribute to the parties a writing
setting forth the arbitral award and the Arbitrator's reasons therefor. Any
award rendered by the Arbitrator shall be final, conclusive and binding upon the
parties, and judgment thereon may be entered and enforced in any court of
competent jurisdiction (subject to Section 7.12), provided that the Arbitrator
shall have no power or authority to grant injunctive relief, specific
performance or other equitable relief.

          (v)   The Arbitrator shall have no power or authority, under the
Commercial Rules or otherwise, to (x) modify or disregard any provision of this
Agreement, including the provisions of this Section 6.2(e), or (y) address or
resolve any issue not submitted by the parties.

          (vi)  In connection with any arbitration proceeding pursuant to this
Agreement, each party shall bear its own costs and expenses, except that the
fees and costs of the AAA and the Arbitrator, the costs and expenses of
obtaining the facility where the arbitration hearing is held, and such other
costs and expenses as the Arbitrator may determine to be directly related to the
conduct of the arbitration and appropriately borne jointly by the parties (which
shall not include any party's attorneys' fees or costs, witness fees (if any),
costs of investigation and similar expenses) shall be shared equally by the
Purchaser and the Seller.

                                       30

     (f) Notwithstanding the other provisions of this Section 6.2, if a third
party asserts (other than by means of a lawsuit) that the Purchaser is liable to
such third party for a monetary or other obligation which may constitute or
result in Damages for which the Purchaser may be entitled to indemnification
pursuant to this Article VI, and the Purchaser reasonably determines that it has
a valid business reason to fulfill such obligation, then (i) the Purchaser shall
be entitled to satisfy such obligation, without prior notice to or consent from
the Seller, (ii) the Purchaser may subsequently make a claim for indemnification
in accordance with the provisions of this Article VI, and (iii) the Purchaser
shall be reimbursed, in accordance with the provisions of this Article VI, for
any such Damages for which it is entitled to indemnification pursuant to this
Article VI (subject to the right of the Seller to dispute the Purchaser's
entitlement to indemnification, or the amount for which it is entitled to
indemnification, under the terms of this Article VI).

     SECTION 6.3 Survival of Representations and Warranties. All representations
and warranties that are covered by the indemnification agreement in Section
6.1(a) shall (a) survive the Closing and (b) shall expire on the date two years
following the Closing Date, except that the representations and warranties set
forth in Sections 2.1 and 2.2 shall survive the Closing without limitation. If
the Purchaser delivers to the Seller, before expiration of a representation or
warranty, either a Claim Notice based upon a breach of such representation or
warranty, or an Expected Claim Notice based upon a breach of such representation
or warranty, then the applicable representation or warranty shall survive until,
but only for purposes of, the resolution of the matter covered by such notice.
If the legal proceeding or written claim with respect to which an Expected Claim
Notice has been given is definitively withdrawn or resolved in favor of the
Purchaser, the Purchaser shall promptly so notify the Seller. The rights to
indemnification set forth in this Article VI shall not be affected by (i) any
investigation conducted by or on behalf of the Purchaser or any knowledge
acquired (or capable of being acquired) by the Purchaser, whether before or
after the date of this Agreement or the Closing Date, with respect to the
inaccuracy or noncompliance with any representation, warranty, covenant or
obligation which is the subject of indemnification hereunder or (ii) any waiver
by the Purchaser of any closing condition relating to the accuracy of
representations and warranties or the performance of or compliance with
agreements and covenants.

     SECTION 6.4 Limitations.

     (a) Notwithstanding anything to the contrary herein, (i) the aggregate
liability of the Seller for Damages under Section 6.1(a) shall not exceed the
lesser of (x) the fair market value of the ClearBlue Shares at the time a claim
is made and (y) $2,000,000, and (ii) the Seller shall be liable only for Damages
under Section 6.1(a) which exceed $250,000, at which point such Damages shall be
fully indemnifiable from the first dollar. In the event the Seller shall be
obligated to pay any Damages under this Article VI, the Seller shall satisfy
such obligations by tendering, in its sole discretion, cash or ClearBlue Shares,
or any combination thereof. In the event the Seller chooses to satisfy its
indemnification obligations hereunder by tendering ClearBlue Shares, the value
of such ClearBlue Shares shall be deemed to equal (i) the fair market value at
the time a claim is made as determined in good faith by the Purchaser's Board of
Directors, if the ClearBlue Shares are not then listed or traded on a national
stock exchange or

                                       31

<PAGE>

quotation system, or (ii) the average closing price of ClearBlue Shares for the
five trading days ending the day prior to the date a claim is made, if the
ClearBlue Shares are listed or traded on a national stock exchange or quotation
system.

     (b) Except with respect to claims based on fraud, after the Closing, the
rights of the Purchaser under this Article VI shall be the sole and exclusive
remedy of the Purchaser with respect to claims resulting from or relating to any
misrepresentation, breach of warranty or failure to perform any covenant or
agreement contained in this Agreement.

     (c) As used in this Agreement:

     "Claim Notice" shall mean written notification which contains (i) a
description of the Damages incurred or reasonably expected to be incurred by the
Purchaser and the Claimed Amount of such Damages, to the extent then known, (ii)

for such Damages and a reasonable explanation of the basis therefor, and (iii) a

reasonably expected to be incurred by the Purchaser.

expenses (including amounts paid in settlement, interest, court costs, costs of
investigators, fees and expenses of attorneys, accountants, financial advisors
and other experts, and other expenses of litigation), other than those costs and
expenses of arbitration of a Dispute which are to be shared equally by the
Purchaser and the Seller as set forth in Section 6.2(e)(vi).

     "Dispute" shall mean the dispute resulting if the Seller in a Response
disputes its liability for all or part of the Claimed Amount.
