State of Delaware. The Company is duly qualified to conduct business and is in
corporate and tax 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 could not reasonably be expected to have a Company Material Adverse
Effect (as defined below). The Company has all requisite corporate power and
authority to (i) enter into and to perform this Agreement in accordance with its
terms and (ii) carry on its businesses as currently conducted or as proposed to
be conducted and to own and use the properties owned and used by it. As used in

          (a) The issuance, sale and delivery of the Shares in accordance with
this Agreement have been duly authorized by all necessary corporate action on
the part of the Company.  The Shares when so issued, sold and delivered against
payment therefor in accordance with the provisions of this Agreement, will be
duly and validly issued, fully paid and nonassessable, and will be free of any
lien or encumbrance, provided however, that the Shares may be subject to
restrictions on transfer under state or federal securities laws as set forth
herein or as otherwise required by such laws at the time a transfer is proposed.
The sale of the Shares is  not, and the issuance of the Shares will not be,
subject to any preemptive right or right of first refusal that has not been
properly waived or complied with.

          (b) Assuming the correctness of the representations made by each
Purchaser in Section 4, no change in applicable law and no unlawful distribution
of the Shares

                                       2

Investor Rights Agreement (as defined herein) and the CPQ Investor Rights
Agreement (as defined herein) has been duly and validly executed and delivered
by the Company and constitutes a valid and binding obligation of the Company,
enforceable against the Company in accordance with its terms, except as such

similar laws affecting or relating to creditors' rights generally, and general
principles of equity.  Subject to compliance with the applicable requirements of
the Securities Act and any applicable state securities laws, and the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), neither the execution and

of the transactions contemplated hereby or thereby, will (a) conflict with or

statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein, in light

                                       3


of the circumstances under which they were made, not misleading. The audited
financial statements and unaudited interim financial statements of the Company
included in the Company SEC Filings (i) complied as to form in all material
respects with applicable accounting requirements and the published rules and
regulations of the SEC with respect thereto when filed, (ii) were prepared in
accordance with GAAP applied on a consistent basis throughout the periods
covered thereby (except as may be indicated therein or in the notes thereto, and
in the case of quarterly financial statements, as permitted by Form 10-Q under
the Exchange Act), (iii) fairly present the consolidated financial condition,
results of operations and cash flows of the Company as of the respective dates
thereof and for the periods referred to therein, and (iv) are consistent with
the books and records of the Company.

          3.6  Absence of Company Material Adverse Change.  Since April 30,
               ------------------------------------------
2000, no event or development has occurred which has had, or could reasonably be
expected to have in the future, a Company Material Adverse Effect, except as
disclosed in Section 3.6 of the Disclosure Schedule.

          3.7  Litigation.  Except as disclosed in the Company SEC Filings,
               ----------
there is no Legal Proceeding which is pending or has been, to the knowledge of
the Company, threatened against the Company or any subsidiary of the Company
which (a) could reasonably be expected to have a Company Material Adverse Effect
or (b) in any manner challenges or seeks to prevent, enjoin, alter or delay the
transactions contemplated by this Agreement.  As used in this Agreement,  the
term "Legal Proceedings" means any action, suit, proceeding, claim, arbitration
or investigation before any Government Entity or before any arbitrator.

          3.8  Conduct of Business. Since April 30, 2000, the business and
               -------------------
operations of the Company and each of its subsidiaries have been conducted in

Section 3.8 of the Disclosure Schedule.

          3.9  Invention Assignment and Confidentiality Agreement. Each
               --------------------------------------------------
employee and consultant or independent contractor of the Company or any of its
subsidiaries whose duties principally include the development of products or
Intellectual Property (as defined blow), and each former employee and consultant
or independent contractor whose duties principally included the development of
products or Intellectual Property, has entered into and executed an invention
assignment and confidentiality agreement or an employment or consulting
agreement containing terms with respect to invention assignments and
confidentiality. No current employee, officer or consultant of the Company has
excluded works or inventions made prior to his or her employment with the
Company from his or her assignment of inventions pursuant to such employee,
officer or consultant's agreement regarding confidential information and
invention assignment, except where such exclusion could not reasonably be
expected to have a Company Material Adverse Effect.  The Company has taken
reasonable security measures to maintain the confidentiality of the Company's
proprietary information.

                                       4


          3.10      Intellectual Property.
                    ---------------------

          (a) Ownership or Right to Use.  The Company or one of its subsidiaries
              -------------------------
has sole title to and owns, or is licensed or otherwise possesses legally
enforceable rights to use, or reasonably expects that it will be able to obtain
licenses or legally enforceable rights to use, all patents or patent
applications, software, know-how, registered or unregistered trademarks and
service marks and any applications therefor, registered or unregistered
copyrights and trade names and any applications therefor, trade secrets or other
confidential or proprietary information ("Intellectual Property") necessary to
enable the Company and its subsidiaries to carry on their respective businesses
as currently conducted or as proposed to be conducted, except where the failure
to own or have rights to use such Intellectual Property could not reasonably be
expected to have a Company Material Adverse Effect.

          (b) Licenses; Other Agreements.  Except as disclosed in Schedule
              --------------------------
3.10(b) of the Disclosure Schedule, neither the Company nor any of its
subsidiaries is currently subject (whether as licensor or licensee) to any
exclusive licenses (whether such exclusivity is temporary or permanent) to any
material portion of the Intellectual Property utilized by the Company or any of
its subsidiaries.  There is not outstanding any license or agreement of any kind
relating to the license by the Company of any Intellectual Property owned by the
Company or any of its subsidiaries, except for agreements with customers of the
Company or any such subsidiary entered into in the ordinary course of business.
Neither the Company nor any of its subsidiaries is obligated to pay any
royalties or other payments to third parties with respect to the marketing,
sale, distribution, manufacture, license or use of any Intellectual Property
(other than off-the-shelf commercial applications), except as it may be so
obligated in the ordinary course of its business.

          (c) No Infringement.  To the Company's knowledge, neither the Company
              ---------------
nor any of its subsidiaries has interfered with, infringed upon,
misappropriated, or otherwise come into conflict with any Intellectual Property
right of a third party, and the Company and its subsidiaries have not received
any charge, complaint, claim, demand, or notice alleging any such interference,
infringement, misappropriation, or violation (including any claim that the
Company or any of its subsidiaries must license or refrain from using any
intellectual property rights of any third party) which, if the subject of any
unfavorable decision, ruling or finding would, individually or in the aggregate,
be reasonably likely to have a Company Material Adverse Effect.

          3.11 Registration Rights.  Except as provided in the CMGI
               -------------------
Investor Rights Agreement (as defined in Section 5.3 hereof) or disclosed in
Schedule 3.11 of the Disclosure Schedule, the Company has not granted or agreed
to grant to any Person any right (including piggyback registration rights), to
have any securities of the Company registered with the SEC or registered or
qualified with any other Governmental Entity.

                                       5


          3.12 Title to Property and Assets.  The properties and assets
               ----------------------------
owned by the Company and each of its subsidiaries are owned by the Company or
such subsidiary free and clear of all mortgages, deeds of trust, liens, charges,
encumbrances and security interests, except for statutory liens for the payment
of current taxes that are not yet delinquent and liens, encumbrances and
security interests that arise in the ordinary course of business and could not
reasonably be expected to have a Company Material Adverse Effect.  With respect
to the property and assets it leases, each of the Company and its subsidiaries
is in compliance with such leases, except for any such noncompliance that,
individually or in the aggregate, could not reasonably be expected to have a
Company Material Adverse Effect.

          3.13 Tax Matters.
               -----------

          (a) To the Company's knowledge, there have been no examinations or
audits of any of the Company's tax returns or reports by any Governmental Entity
having jurisdiction over the Company.  To the Company's knowledge, each of the
Company and its subsidiaries has filed all federal, state, county and local tax
returns required to have been filed by them and paid all taxes shown to be due
on such returns.  There are in effect no waivers of applicable statutes of
limitations with respect to taxes for any year.

          (b) The Company has not elected pursuant to the Internal Revenue Code
of 1986, as amended (the "Code"), to be treated as an "S" corporation or a
collapsible corporation pursuant to Section 1362(a) or Section 341(f) of the
Code, respectively, nor to the Company's knowledge has it made any other
elections pursuant to the Code (other than elections which relate solely to
matters of accounting, depreciation or amortization) which would have a Company
Material Adverse Effect.

          3.14 ERISA.  The Company does not sponsor or participate in any
               -----
employee benefit plan subject to the Employee Retirement Income Security Act of
1974, as amended ("ERISA"), except for any employee benefit plan that CMGI
sponsors or in which CMGI participates or except as disclosed on Section 3.14 of
the Disclosure Schedule.  The Company is not required to contribute to any
"multi-employer plan" as defined in ERISA, Section 3(37), nor has the Company
ever contributed to or withdrawn from such a multi-employer plan.

          3.15 Employment Matters.  There are no complaints pending or, to the
               ------------------
Company's knowledge, threatened before any Governmental Entity alleging unfair
labor practices or unlawful discrimination or, to the Company's knowledge, is
there any basis for any such claim.  There are no existing or, to the Company's
knowledge, threatened labor strikes, disputes, grievances, controversies or
other labor troubles affecting the Company which could reasonably be expected to
have, individually or in the aggregate, a Company Material Adverse Effect.  The
Company is not a party to any collective bargaining agreement

                                       6


with any labor union.

          3.16 Brokers.  Except for the fee payable by the Company to Greenhill
               -------
& Co., LLC with respect to shares of Common Stock purchased by Purchasers other
than CMGI, no broker, finder, or investment banker is entitled to any brokerage,
finder's, or other fee or commission in connection with the transactions
contemplated by this Agreement.  The Company will indemnify and save each
Purchaser harmless from and against any and all claims, liabilities or
obligations with respect to brokerage or finders' fees or commissions, or
consulting fees in connection with the transactions contemplated by this
Agreement asserted by any Person on the basis of any agreement, arrangement,
statement or representation alleged to have been made by the Company.

          3.17  Compliance.  The Company is not in violation of any applicable
                ----------
statute, rule, regulation, order or restriction of any domestic or foreign
government or any instrumentality or agency thereof in respect of the conduct of
its business or the ownership of its properties which violation would have a
Company Material Adverse Effect.  The Company has all franchises, permits,
licenses and any similar authority necessary for the conduct of its business as
presently conducted, the lack of which would have a Company Material Adverse
Effect, and believes that it can obtain, without undue burden or expense, any
similar authority for the conduct of its business as proposed to be conducted.

          3.18 Environmental.  The Company, the operation of its business and
               -------------
any real property that the Company owns or has owned, leases or has leased or
otherwise occupies or uses or has occupied or used  (the "Premises") are, to the
Company's knowledge, in compliance with all applicable Environmental Laws (as
defined below) and orders or directives of any governmental authorities having
jurisdiction under such Environmental Laws, except where the failure to comply
could not reasonably be expected to have a Company Material Adverse Effect.  The
Company has not received any citation, directive, letter or other communication,
written or oral, or any notice of any proceeding, claim or lawsuit, from any
person arising out of the ownership or occupation of the Premises, or the
conduct of its operations, and the Company is not aware of any basis therefor.
To the Company's knowledge, no material expenditures are or will be required in
order to comply with any Environmental Laws. For purposes of this Agreement, the
term "Environmental Laws" shall mean any Federal, state, local or foreign law,
ordinance, rule, regulation, permit and authorization pertaining to the
protection of human health or the environment.

     4.   Representations of the Purchasers.  Each Purchaser, severally and not
          ---------------------------------
jointly, represents and warrants to the Company as follows:

          4.1  Investment.  The Purchaser is acquiring the Shares for its own
               ----------
account for investment and not with a view to, or for sale in connection with,
any distribution thereof, nor with any present intention of distributing or
selling the same.  The Purchaser is an "accredited investor" as defined in Rule
501(a) under the Securities Act.

                                       7


          4.2  Incorporation, Authority, Validity and Noncontravention.  The
               -------------------------------------------------------
Purchaser is duly organized, validly existing and in good standing under the
laws of its jurisdiction of incorporation.  The Purchaser has full power and
authority to enter into and to perform this Agreement in accordance with its
terms. This Agreement has been duly and validly executed and delivered by the
Purchaser and constitutes a valid and binding obligation of the Purchaser,
enforceable against the Purchaser in accordance with its terms, except as such
enforceability may be limited by bankruptcy, insolvency, moratorium or other
similar laws affecting or relating to creditors' rights generally, and general
principles of equity.  Subject to compliance with the applicable requirements of
the Securities Act and any applicable state securities laws, and the Exchange
Act, neither the execution and delivery by the Purchaser of this Agreement, nor
the consummation by the Purchaser of the transactions contemplated hereby or
thereby, will (a) conflict with or violate any provision of the charter or by-
laws of the Purchaser, (b) require on the part of the Purchaser any filing with,
or permit, authorization, consent or approval of, any Governmental Entity, (c)
conflict with, result in breach of, constitute (with or without due notice or

obligations under, create in any party any right to terminate, modify or cancel,
or require any notice, consent or waiver under, any contract or instrument to
which the Purchaser is a party or by which it is bound or to which any of its
assets are subject, except for (i) any conflict, breach, default, acceleration,
termination, modification or cancellation which would not have a Purchaser
Material Adverse Effect or adversely affect the consummation of the transactions
contemplated hereby or (ii) any notice, consent or waiver the absence of which
would not have a Purchaser Material Adverse Effect or adversely affect the
consummation of the transactions contemplated hereby, or (d) violate any order,
writ, injunction, decree, statute, rule or regulation applicable to the
Purchaser or any of its properties or assets. As used in this Agreement,
"Purchaser Material Adverse Effect" means a material adverse effect on or a
material adverse change in, or group of such effects on or changes in, the
assets, liabilities, business, condition (financial or otherwise), results of
operations or prospects of the Purchaser and its subsidiaries, taken as a whole,
excluding any material adverse effect (a) demonstrably shown to have been
proximately caused by the public announcement of this Agreement or any of the
transactions contemplated thereby, (b) attributable to any legal proceeding
brought by or on behalf of stockholders of the Purchaser alleging that the Board
of Directors of the Purchaser breached its fiduciary duties in connection with
its approval of this Agreement and the transaction contemplated hereby, or (c)
arising or resulting from general industry, economic or stock market conditions
that affect the Purchaser (or the markets in which the Purchaser competes) in a
manner not disproportionate to the manner in which such conditions affect other
companies in the industries or markets in which the Purchaser competes.

          4.3  Experience.  The Purchaser has carefully reviewed the
representations concerning the Company contained in this Agreement, and has made
detailed inquiry concerning the Company, its business and its personnel; the

Purchaser has sufficient knowledge and experience in finance and business that
he, she or it is capable of evaluating the risks and merits of his, her or its
investment in the Company and such Purchaser is able financially to bear the
risks thereof.

          4.4  Brokers.  The Purchaser (i) has not retained a finder or broker
               -------
in connection with the transactions contemplated by this Agreement, and (ii)
will indemnify and save the Company harmless from and against any and all
claims, liabilities or obligations with respect to brokerage or finders' fees or
commissions, or consulting fees in connection with the transactions contemplated
by this Agreement asserted by any Person on the basis of any agreement,
arrangement, statement or representation alleged to have been made by such
indemnifying party.

               8.  Transfer of Shares.
                   ------------------

               -----------------
(ii) any other shares of capital stock of the Company issued in respect of such
shares (as a result of stock splits, stock dividends, reclassifications,

Stock which are Restricted Shares shall cease to be Restricted Shares (x) upon
any sale pursuant to Section 4(1) of the Securities Act or Rule 144 under the
Securities Act or (y) at such time as they become eligible for sale under Rule
144(k) under the Securities Act.

               8.2  Requirements for Transfer.
                    -------------------------

          (a) Restricted Shares shall not be sold or transferred unless either
(i) they first shall have been registered under the Securities Act, or (ii) the
Company first shall have been furnished with an opinion of legal counsel,
reasonably satisfactory to the Company, to the

                                       10


effect that such sale or transfer is exempt from the registration requirements
of the Securities Act.

counsel shall be required for (i) a transfer by a Purchaser to a wholly owned
subsidiary or Affiliate (as defined herein) of that Purchaser or (ii) a transfer

          sold or otherwise transferred, pledged or hypothecated unless and
          until such shares are registered under such Securities Act or an
          opinion of counsel satisfactory to the Company is obtained to the
          effect that such registration is not required."

The Company shall remove from the certificates representing any Restricted
Shares, at the request of the holder thereof, at such time as they become
eligible for resale pursuant to Rule 144(k) under the Securities Act or sold
pursuant to an effective registration statement under the Securities Act.

9.  Indemnification.
    ---------------

          9.1      Agreement to Indemnify.
                   ----------------------

          (a) Company Indemnity.  Each Purchaser, its Affiliates and Associates
              -----------------
(each as defined in Section 9.3), and each officer, director, stockholder,
employer, representative and agent of any of the foregoing (collectively, the
"Purchaser Indemnitees"), shall each be indemnified by the Company and held
harmless to the extent set forth in this Section 9 with respect to any and all
Damages (as defined in Section 9.5) reasonably incurred by any Purchaser
Indemnitee as a proximate result of any inaccuracy or misrepresentation in, or
breach of, any representation, warranty, covenant or agreement made by the
Company in this Agreement (including any exhibits, schedules or disclosure
schedules hereto).

          (b) Purchaser Indemnity.  The Company, its respective Affiliates and
              -------------------
Associates, and each officer, director, stockholder, employer, representative
and agent of any of the foregoing (collectively, the "Company Indemnitees"),
shall each be indemnified and held harmless to the extent set forth in this
Section 9 by each Purchaser, severally and not

                                       11


jointly, in respect of any and all Damages reasonably incurred by any Company
Indemnitee as a proximate result of any inaccuracy or misrepresentation in, or
breach of, any representation, warranty, covenant or agreement made by that
Purchaser in this Agreement (including any exhibits, schedules or disclosure
schedules hereto).

          (c) Equitable Relief.  Nothing set forth in this Section 9 shall be
              ----------------
deemed to prohibit or limit the right of any Purchaser Indemnitee or Company
Indemnitee (an "Indemnitee") at any time before, at or after the Closing, to
seek injunctive or other equitable relief for the failure of any "Indemnifying
Party" (which, for purposes hereof, in the case of an Purchaser Indemnitee,
means the Company and, in the case of a Company Indemnitee, means the respective
Purchaser) to perform or comply with any covenant or agreement contained herein.

          9.2  Survival.  All representations and warranties of each Purchaser
               ---------
and the Company contained herein and all claims of any Indemnitee in respect of
any inaccuracy, misrepresentation or breach shall survive the Closing until the
first anniversary of the Closing Date, regardless of whether the applicable
statute of limitations, including extensions thereof, may expire; provided,
however, notwithstanding the foregoing, the representations and warranties of
the Company contained in Section 3.3 shall survive the Closing until such time
as the applicable statute of limitations expires.  All covenants and agreements
of each Purchaser and the Company contained in this Agreement shall survive the
Closing in perpetuity (except to the extent any such covenant or agreement shall
terminate or expire by its terms).  All claims of any Indemnitee in respect of
any breach of such covenants or agreements shall survive the Closing until the
expiration of one year following the non-breaching party's obtaining actual
knowledge of such breach; provided that the covenant or agreement has not
terminated or expired by its terms prior to the date the claim is made.

          9.3  Claims for Indemnification.  If any Indemnitee shall believe
               --------------------------
that such Indemnitee is entitled to indemnification pursuant to this Section 9
in respect of any Damages, such Indemnitee shall give the appropriate
Indemnifying Party prompt written notice thereof.  Any such notice shall set
forth in reasonable detail and to the extent then known the basis for such claim
for indemnification.  The failure of such Indemnitee to give notice of any claim
for indemnification promptly shall not adversely affect such Indemnitee's right
to indemnity hereunder except to the extent that such failure adversely affects
the right of the Indemnifying Party to assert any reasonable defense to such
claim.  Each such claim for indemnity shall expressly state that the
Indemnifying Party shall have only the 20 Business Day period referred to below
in this Section 9.3 to dispute or deny such claim.  As used in this Agreement,
the term "Business Day" means each Monday, Tuesday, Wednesday, Thursday or
Friday that banks in Boston, Massachusetts are not required by law to be closed.
The Indemnifying Party shall have 20 Business Days following its receipt of such
notice either (i) to acquiesce in such claim by giving such Indemnitee written
notice of such acquiescence or (ii) to object to the

                                       12


claim by giving such Indemnitee written notice of the objection. If the
Indemnifying Party does not object thereto within such 20 Business Day period,
such Indemnitee shall be entitled to be indemnified for all Damages reasonably
and proximately incurred by such Indemnitee in respect of such claim. If the
Indemnifying Party objects to such claim in a timely manner, the senior
management of the Company and the relevant Purchaser or Purchasers shall meet to
attempt to resolve such dispute. If the dispute cannot be resolved by senior
management of the Company and Purchaser, either party may make a written demand
for formal dispute resolution and specify therein the scope of the dispute.
Within 30 days after such written notification, the Parties agree to meet for
one day with an impartial mediator and consider dispute resolution alternatives
other than litigation. If an alternative method of dispute resolution is not
agreed upon within 30 days after the one-day mediation, either party may begin
litigation proceedings. Nothing in this Section 9.3 shall be deemed to require
arbitration.

          9.4  Defense of Claims.  In connection with any claim that may give
               -----------------
rise to indemnity under this Section 9 resulting from or arising out of any
claim or Proceeding (as defined in Section 9.5 below) against any Indemnitee by
a Person that is not a party hereto, the Indemnifying Party may (unless such
Indemnitee elects not to seek indemnity hereunder for such claim) but shall not
be obligated to, upon written notice to the relevant Indemnitee, assume the
defense of any such claim or Proceeding if the Indemnifying Party with respect
to such claim or Proceeding acknowledges to the Indemnitee the Indemnitee's
right to indemnify pursuant hereto the extent provided herein (as such claim may
have been modified through written agreement of the Parties) and provides
assurances, reasonably satisfactory to such Indemnitee, that the Indemnifying
Party shall be financially able to satisfy such claim to the extent provided
herein if such claim or Proceeding is decided adversely; provided, however, that
nothing set forth herein shall be deemed to require the Indemnifying Party to
waive any cross-claims or counterclaims for Damages the Indemnifying Party may
have against the Indemnitee.  The Indemnitee shall be entitled to retain
separate counsel, reasonably acceptable to the Indemnifying Party, if the
Indemnitee shall determine, upon the written advice of counsel, that an actual
or potential conflict of interest exists between the Indemnifying Party and the
Indemnitee in connection with such claim or Proceeding.  The Indemnifying Party
shall be obligated to pay the reasonable fees and expenses of such separate
counsel to the extent the Indemnitee is entitled to indemnification by the
Indemnifying Party with respect to such claim or Proceeding under this Section
9.4.  If the Indemnifying Party assumes the defense of any such claim or
Proceeding, the Indemnifying Party shall select counsel reasonably acceptable to
such Indemnitee to conduct the defense of such claim or Proceeding, shall take
all steps necessary in the defense or settlement thereof and shall at all times
diligently and promptly pursue the resolution thereof.  If the Indemnifying
Party shall have assumed the defense of any claim or Proceeding in accordance
with this Section 9.4, the Indemnifying Party shall be authorized to consent to
a settlement of, or the entry of any judgment arising from, any such claim or
Proceeding; provided, however, that the Indemnifying Party shall pay or cause to
be

                                       13


paid all amounts arising out of such settlement or judgment concurrently with
the effectiveness thereof; provided, further, that the Indemnifying Party shall
not be authorized to encumber any of the assets of any Indemnitee or to agree to
any restriction that would apply to any Indemnitee or to its conduct of business
without the prior written consent of the Indemnitee; and provided, further, that
a condition to any such settlement shall be a complete release of such
Indemnitee and its Affiliates, directors, officers, employees an agents with
respect to such claim, including any reasonably foreseeable collateral
consequences thereof.  Such Indemnitee shall be entitled to participate in (but
not control) the defense of any such action, with its own counsel and at its own
expense.  Each Indemnitee shall, and shall cause each of its Affiliates,
directors, officers, employees and agents to, cooperate fully with the
Indemnifying Party in the defense of any claim or Proceeding being defended by
the Indemnifying Party pursuant to this Section 9.4.  If the Indemnifying Party
does not assume the defense of any claim or Proceeding resulting therefrom in
accordance with the terms of this Section 9.4, such Indemnitee may defend
against such claim or Proceeding in such manner as it may deem appropriate,
including settling such claim or Proceeding after giving notice of the same to
the Indemnifying Party, on such terms as such Indemnitee may deem appropriate.
If any Indemnifying Party seeks to question the manner in which such Indemnitee
defended such claim or Proceeding or the amount or nature of any such
settlement, such Indemnifying Party shall have the burden to prove by a
preponderance of the evidence that such Indemnitee did not defend such claim or
Proceeding in a reasonably prudent manner.

     The Investor Rights Agreement is hereby amended by replacing the definition

     in respect of such the shares of Common Stock referred to in clause (a)
     through (d) (because of stock splits, stock dividends, reclassifications,
     recapitalizations or similar events); provided, however, that shares of
     Common Stock which are Registrable Shares shall cease to be Registrable
     Shares upon (i) any sale pursuant to a Registration Statement or Rule 144
     under the Securities Act or (ii) any sale in any manner to a person or
     entity which, by virtue of Section 3.4 of this Agreement, is not entitled
