desires to receive from the Company, warrants to purchase shares of the
Company's Common Stock on the terms and conditions set forth in this Agreement
in consideration of the execution and delivery by the Investor of a "Netcenter

this Agreement and the Netcenter Services Agreement, and to consummate the
transactions contemplated hereby and thereby, including the issuance of the

The Company is qualified to do business and is in good standing in each
jurisdiction in which the failure to so qualify would have a Material Adverse
Effect on the Company. As used in this Agreement, "Material Adverse Effect"
means a material adverse effect on, or a material adverse change in, or a group
of such effects on or changes in, the business, operations, financial condition,
results of operations, prospects, assets or liabilities of the Company or the
Investor, as applicable; provided, however, that any adverse change or effect
that is primarily caused by (i) conditions affecting the United States economy
generally, (ii) conditions generally affecting the Internet industry or (iii)
the announcement or pendency of this Agreement or the Netcenter Services
Agreement, shall not be taken into account in determining whether there has been
or would be a "Material Adverse Effect;" provided further, that any adverse
change in the stock price of the Company or the Investor, as applicable, as
quoted on the Nasdaq National Market shall not be taken into account in
determining whether there has been or would be a "Material Adverse Effect."

                  3.2      Capitalization.  As of the date of this Agreement the
capitalization of the Company is as follows:

there are not outstanding any options, warrants, rights (including conversion or
preemptive rights) or agreements for the purchase or acquisition from the
Company of any shares of its capital stock or any securities convertible into or
ultimately exchangeable or exercisable for any shares of the Company's capital
stock. Except for any stock repurchase rights of the Company under the Plans, no
shares of the Company's outstanding capital stock, or stock issuable upon
exercise, conversion or exchange of any outstanding options, warrants or rights,
or other stock issuable by the Company, are subject to any rights of first
refusal or other rights to purchase such stock (whether in favor of the Company
or any other person), pursuant to any agreement, commitment or other obligation
of the Company.

                  3.3 Due Authorization. All corporate action on the part of the

affecting enforcement of creditors' rights generally, and (ii) the effect of
rules of law governing the availability of equitable remedies.

                           (b) Based in part on the representations made by the
Investor in Section 4 hereof, the Warrants are being issued, and upon exercise
thereof the Shares will be issued, in compliance with the registration
requirements of the Securities Act of 1933, as amended (the "Securities Act"),
or in compliance with applicable exemptions therefrom, and the registration and
qualification requirements of all applicable securities laws of the states of
the United States.

                  3.5 Governmental Consents. No consent, approval, order or
authorization of, or registration, qualification, designation, declaration or
filing with, any federal, state or local


                                       4

Agreement. All such qualifications and filings have been made, in the case of

                  3.6 Non-Contravention. The execution, delivery and performance
of this Agreement and the Netcenter Services Agreement by the Company, and the
consummation by the Company of the transactions contemplated hereby and thereby,
including the issuance of the Warrants and the issuance of the Shares upon

Articles of Incorporation or Bylaws of the Company; (ii) constitute a material
violation of any provision of any federal, state, local or foreign law, rule or
regulation binding upon or applicable to the Company; or (iii) constitute a
default or require any consent under, give rise to any right of termination,
cancellation or acceleration of, or to a loss of any benefit to which the
Company is entitled under, or result in the creation or imposition of any lien,
claim or encumbrance on any assets of the Company under, any contract to which
the Company is a party or any permit, license or similar right relating to the
Company or by which the Company may be bound or affected in such a manner as
would have a Material Adverse Effect on the Company.

                  3.7 Litigation. There is no action, suit, proceeding, claim,
arbitration or investigation ("Action") pending: (a) that seeks to prevent,
enjoin, alter or delay the transactions contemplated by this Agreement and the
Netcenter Services Agreement; or (b) that has not previously been disclosed in
one of the SEC Documents (as defined below) and is currently required to be

the "SEC Documents"). Each of the SEC Documents, as of the respective date
thereof, did not, as of the date thereof, contain any untrue statement of a
material fact or omit to state a material fact necessary in order to make the

                           (b) The Form 10-K contains the Company's audited

statements, reports and proxy statements required to be filed by it under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the
Securities Act. The audited and unaudited consolidated financial statements of
the Company included in the SEC Documents filed prior to the date hereof fairly
present, in conformity with generally accepted accounting principles (" GAAP ")
(except as otherwise permitted by Form 10-Q) applied on a consistent basis
(except as may be indicated in the notes thereto), the consolidated financial
position of the Company and its consolidated subsidiaries as at the date thereof
and the consolidated results of their operations and cash flows for the periods
then ended (subject to normal year and audit adjustments in the case of
unaudited interim financial statements).

                           (c) Except as and to the extent reflected or reserved
against in the Company's Audited Financial Statements (including the notes

liquidated or unliquidated, secured or unsecured, joint or several, due or to
become due, vested or unvested, executory, determined or determinable) other
than: (i) liabilities incurred in the ordinary course of business since the
Balance Sheet Date that are consistent with the Company's past practices, (ii)
liabilities with respect to agreements to which the Investor is a party, and
(iii) other liabilities that either individually or in the aggregate, would not
result in a Material Adverse Effect on the Company.

                           (d) The Company meets the requirements for the use of
Form S-3 for registration of the sale by the Investor of the Registrable
Securities (as defined below), and the Company covenants that it shall file all
reports required to be filed by the Company with the SEC in a timely manner so
as to maintain such eligibility for the use of Form S-3.

                  3.10 Absence of Certain Changes Since Balance Sheet Date.

acquisition by the Company or any subsidiary of the Company of any outstanding
shares of the Company's capital stock;

                                       6

   7

                           (b) any damage, destruction or loss, whether or not
covered by insurance, except for such occurrences that have not resulted, and
are not expected to result, in a Material Adverse Effect on the Company;

                           (c) any waiver by the Company of a valuable right or
of a material debt owed to it, except for such waivers that have not resulted,
and are not expected to result, in a Material Adverse Effect on the Company;

                           (d) any material change or amendment to, or any
waiver of any material rights under, a material contract or arrangement by which
the Company or any of its assets or properties is bound or subject, except for
changes, amendments, or waivers that are expressly provided for or disclosed in
this Agreement or that have not resulted, and are not expected to result, in a
Material Adverse Effect on the Company;

                           (e) any change by the Company in its accounting
principles, methods or practices or in the manner it keeps its accounting books
and records, except any such change required by a change in GAAP; and

                           (f) any other event or condition of any character,
except for such events and conditions that have not resulted, and cannot
reasonably be expected to result, in a Material Adverse Effect on the Company.

                  3.11 Full Disclosure. The information contained in this
Agreement, the Disclosure Letter, and the SEC Documents, together with the other
written disclosures made by the Company to the Investor in the course of their
discussions leading to this Agreement, taken together, with respect to the
business, operations, assets, results of operations and financial condition of
the Company is true and complete in all material respects and does not omit to
state any material fact necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading.


         4.  REPRESENTATIONS, WARRANTIES AND CERTAIN AGREEMENTS OF THE INVESTOR.

         The Investor hereby represents and warrants to the Company as follows,
provided, however, that nothing set forth in this Article 4 shall limit or
modify the representations and warranties made by the Company in Article 3.

                  4.1 Authorization. This Agreement has been duly authorized by
all necessary corporate action on the part of the Investor. The Agreement
constitutes the Investor's valid and legally binding obligation, enforceable
against it in accordance with its terms, except as may be limited by (a)
applicable bankruptcy, insolvency, reorganization or other laws of general
application relating to or affecting the enforcement of creditors' rights
generally and (b) the effect of rules of law governing the availability of
equitable remedies. The Investor has full corporate power and authority to enter
into this Agreement.

                                       7

   8

                  4.2 Acquisition for Own Account. The Warrants are being
acquired, and the Shares will be acquired, for the Investor's own account, not
as a nominee or agent, and not with a view to the public resale or distribution
thereof without registration under the Securities Act or an exemption therefrom.

                  4.3      Accredited Investor Status.  The Investor is an 
"accredited investor" within the meaning of Regulation D promulgated under the
Securities Act.

                  4.4 Restricted Securities. The Investor understands that the
Warrants to be issued to the Investor hereunder and the Shares issuable upon
exercise thereof are "restricted securities" under the Securities Act inasmuch
as they are being acquired or will be acquired from the Company in a transaction
not involving a public offering and that under the Securities Act and applicable
regulations thereunder such securities may be resold without registration under
the Securities Act only in certain limited circumstances. The Investor is
familiar with Rule 144 of the SEC, as presently in effect, and understands the
resale limitations imposed thereby and by the Securities Act.

                  4.5 Governmental Consents. No consent, approval, order or
authorization of, or registration, qualification, designation, declaration or
filing with, any federal, state or local governmental authority on the part of
the Investor is required in connection with the consummation of the transactions
contemplated hereby and by the Netcenter Services Agreement, including the
acquisition of the Warrants and the purchase of the Shares upon exercise
thereof. All such qualifications have been made, in the case of qualifications,
on or prior to the date hereof, and have been or will be made, in the case of
filings, within the time prescribed by law.

                  4.6 Non-Contravention. The execution, delivery and performance
of this Agreement and the Netcenter Services Agreement by the Investor, and the
consummation by the Investor of the transactions contemplated hereby and
thereby, including the acquisition of the Warrants and the purchase of the
Shares upon exercise thereof, do not and will not (i) contravene or conflict
with the Certificate of Incorporation or Bylaws of the Investor; (ii) constitute
a material violation of any provision of any federal, state, local or foreign
law, rule or regulation binding upon or applicable to the Investor; or (iii)
constitute a default or require any consent under, give rise to any right of
termination, cancellation or acceleration of, or to a loss of any benefit to
which the Investor is entitled under, or result in the creation or imposition of
any lien, claim or encumbrance on any assets of the Investor under, any contract
to which the Investor is a party or any permit, license or similar right
relating to the Investor or by which the Investor may be bound or affected in
such a manner as would have a Material Adverse Effect on the Investor.

                  4.7 Further Limitations on Disposition. Without in any way
limiting the representations set forth above, the Investor agrees not to make
any disposition of all or any portion of the Warrants without the prior written
consent of the Company, which consent may be withheld in the Company's sole
discretion. The Investor further agrees not to make any disposition of all or
any portion of the Shares unless and until:

                                       8

   9

                           (a) there is then in effect a registration statement
under the Securities Act covering such proposed disposition and such disposition
is made in accordance with such registration statement; or

                           (b) the Investor has notified the Company of the 
proposed disposition and has furnished the Company with a statement of the
circumstances surrounding the proposed disposition, and the Investor has
furnished the Company, at the expense of the Investor or its transferee, with an
opinion of counsel, reasonably satisfactory to the Company, that such
disposition will not require registration of such securities under the
Securities Act.

Notwithstanding the provisions of paragraphs (a) and (b) of this Section 4.7, no
such registration statement or opinion of counsel will be required for any
transfer of any Shares in compliance with SEC Rule 144, Rule 144A or Rule
145(d), or if such transfer otherwise is exempt from the registration
requirements of the Securities Act in the opinion of the Company's counsel.
Furthermore, notwithstanding the other provisions of this Section 4.7, the
Investor shall be permitted to transfer all or any portion of the Warrants (i)
to an underwriter of a public offering of Common Stock if and only if the
Warrants (or any such portion) shall be immediately exercised by such
underwriter and the Shares issued upon such exercise are immediately sold to the
public, (ii) to any affiliate (as that term is defined in the Securities Act) of
the Investor, or (iii) in connection with any merger or consolidation to which
the Investor is a party, any sale of all or substantially all of the Investor's
assets or any other acquisition of the Investor.

                  4.8      Legends.  Certificates evidencing the Warrants and 
the Shares will bear the following legend:

                  THE SECURITIES REPRESENTED HEREBY HAVE 
                  NOT BEEN REGISTERED UNDER THE SECURITIES 
                  ACT OF 1933, AS AMENDED (THE "ACT"), OR
                  UNDER THE SECURITIES LAWS OF CERTAIN 
                  STATES. THESE SECURITIES ARE SUBJECT TO 
                  RESTRICTIONS ON TRANSFERABILITY AND RESALE 
                  AND MAY NOT BE TRANSFERRED OR RESOLD 
                  EXCEPT AS PERMITTED UNDER THE ACT AND THE 
                  APPLICABLE STATE SECURITIES LAWS, PURSUANT 
                  TO REGISTRATION OR EXEMPTION THEREFROM.

The legend set forth above will be removed by the Company from any certificate
evidencing Shares upon delivery to the Company of an opinion by counsel,
reasonably satisfactory to the Company, that a registration statement under the
Securities Act is at that time in effect with respect to the legended security
or that such security can be freely transferred in a public sale without such a
registration statement being in effect and that such transfer will not
jeopardize the exemption or exemptions from registration pursuant to which the
Company issued the Shares.

         5.   NO TREATMENT AS AFFILIATE;  REGISTRATION

                  5.1 No Treatment as Affiliate. On the basis of the facts now
in its possession, upon and following the Closing of the transactions
contemplated by this Agreement, the Company shall not treat the Investor as an
"affiliate" of the Company (as such term is defined in the Securities Act) for
purposes of any federal or state securities laws.

                  5.2      Registration.

                           (a) Certain Definitions.  As used in this Section 
5.2, the following terms shall have the following respective meanings:

                            "Registrable Securities" shall mean (i) all Shares
issued or issuable upon exercise of the Warrants, and (ii) any shares of Common
Stock of the Company issued as (or issuable upon conversion or exercise of any
warrant, right or other security which is issued as) a stock dividend or other
distribution with respect to, or in exchange for or in replacement of, any
Shares; provided, however, that shares of Common Stock or other securities shall
only be treated as Registrable Securities if and so long as they have not been
sold to or through a broker or dealer or underwriter in a public distribution or
a public securities transaction.

                            The terms "register," "registered" and 
"registration" refer to a registration effected by preparing and filing a
registration statement in compliance with the Securities Act, and the
declaration or ordering of the effectiveness of such registration statement.

                            "Registration Statement" shall mean the registration
statement of the Company under the Securities Act contemplated by Section 5.2(b)
below.

                           (b) Registration.

                                    (i)     Mandatory Registration.  The Company
shall prepare and file with the SEC as soon as practicable after the Closing,
but no later than ten (10) days after the Closing Date, a Registration Statement
on Form S-3 (or, if Form S-3 is not then available, on such form of Registration
Statement as is then available to effect a registration of all of the
Registrable Securities) covering the resale of the Registrable Securities. The
Company shall use its best efforts to cause the Registration Statement to become
effective as soon as practicable after filing, but in no event later than the
first to occur of (i) the third (3rd) day after the SEC notifies the Company
that the Registration Statement will not be reviewed by the SEC or that the SEC
does not have any further comments on the Registration Statement and (ii) ninety
(90) days after the Closing Date, and to keep such Registration Statement
current and effective pursuant to SEC Rule 415 at all times until such date as
is the earlier of (A) the date on which all of the Registrable Securities have
been sold, and (B) the date on which all of the Registrable Securities (in the
reasonable opinion of counsel to the Investor) may be immediately sold to the
public without registration or restriction pursuant to Rule 144 under the
Securities Act within a single three-month period (the "Registration Period").
The Registration Statement (and each amendment or supplement thereto, and each
request for acceleration of effectiveness thereof) 


                                       10

   11

shall be provided to, and be subject to the reasonable approval of, the Investor
and its counsel prior to the filing or other submission thereof to the SEC.

                                    (ii)    Permitted Delay Periods; Suspension
of Sales. If at any time prior to the expiration of the Registration Period, the
Chief Executive Officer of the Company has determined in good faith that (A)
compliance by the Company with its disclosure obligations in connection with the
Registration Statement would be seriously detrimental to the Company and its
shareholders, or (B) the Company then is unable to comply with its disclosure
obligations or SEC requirements in connection with the Registration Statement,
then in either such case the Company shall not be required to maintain the
effectiveness thereof or amend or supplement the Registration Statement for a
period (a "Permitted Delay Period") expiring upon the earlier to occur of (I)
the date on which such material information is disclosed to the public or ceases
to be material or the Company is able to so comply with its disclosure
obligations and SEC requirements, or (II) sixty (60) days after the Chief
Executive Officer of the Company makes such good faith determination. The
Company will give prompt written notice to the Investor of each Permitted Delay
Period. Such notice shall state to the extent, if any, as is practicable, an
estimate of the duration of such Permitted Delay Period. The Investor, by its
acceptance of any Registrable Securities, agrees that, upon receipt of such
notice it will forthwith discontinue disposition of the Registrable Securities
pursuant to the Registration Statement, and will not deliver any prospectus
forming a part thereof in connection with any sale of Registrable Securities,
until the expiration of such Permitted Delay Period. There shall not be more
than one (1) Permitted Delay Period in any twelve (12) month period.

                           (c) Obligations of the Company. In connection with
the registration of the Registrable Securities, the Company shall have the 
following obligations:

                                    (i)     No Registration Statement (including
any amendments or supplements thereto and prospectuses contained therein and all
documents incorporated by reference therein) shall contain any untrue statement
of a material fact or omit to state a material fact required to be stated
therein, or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

                                    (ii) The Company shall prepare and file with
the SEC such amendments (including post-effective amendments) and supplements to
the Registration Statement and the prospectus used in connection with the
Registration Statement as may be necessary to keep the Registration Statement
effective at all times during the Registration Period and, during such period,
comply with the provisions of the Securities Act with respect to the disposition
of all Registrable Securities of the Company covered by the Registration
Statement until such time as all of such Registrable Securities have been
disposed of in accordance with the intended methods of disposition by the seller
or sellers thereof as set forth in the Registration Statement.

                                    (iii) The Company shall furnish to the
Investor and its legal counsel (A) promptly after the same is prepared and
publicly distributed, filed with the SEC or received by the Company, one copy of
the Registration Statement and any amendment thereto,


                                       11

   12

each preliminary prospectus and prospectus and each amendment or supplement
thereto, and each letter written by or on behalf of the Company to the SEC or
the staff of the SEC (including, without limitation, any request to accelerate
the effectiveness of the Registration Statement or amendment thereto), and each
item of correspondence from the SEC or the staff of the SEC, in each case
relating to the Registration Statement (other than any portion, if any, thereof
which contains information for which the Company has sought confidential
treatment), (B) on the date of effectiveness of the Registration Statement or
any amendment thereto, a notice stating that the Registration Statement or
amendment has been declared effective, and (C) such number of copies of a
prospectus, including a preliminary prospectus, and all amendments and
supplements thereto and such other documents as the Investor may reasonably
request in order to facilitate the disposition of the Registrable Securities.

                                    (iv) The Company shall (A) register and
qualify the Registrable Securities covered by the Registration Statement under
such securities or "blue sky" laws of such jurisdictions as the Investor
reasonably requests, (B) prepare and file in those jurisdictions such amendments
(including post-effective amendments) and supplements to such registrations and
qualifications as may be necessary to maintain the effectiveness thereof during
the Registration Period, (C) take such other actions as may be necessary to
maintain such registrations and qualifications in effect at all times during the
Registration Period, and (D) take all other actions reasonably necessary or
advisable to qualify the Registrable Securities for sale in such jurisdictions;
provided, however, that the Company shall not be required in connection
therewith or as a condition thereto to (I) qualify to do business in any
jurisdiction where it would not otherwise be required to qualify but for this
Section 5.2(c)(iv), (II) subject itself to general taxation in any such
jurisdiction, (III) file a general consent to service of process in any such
jurisdiction, or (IV) make any change in its charter or bylaws, which in each
case the Board of Directors of the Company determines to be contrary to the best
interests of the Company and its shareholders.

                                    (v)     As promptly as practicable after 
becoming aware of such event, the Company shall notify the Investor of the
happening of any event, as a result of which the prospectus included in the
Registration Statement, as then in effect, includes an untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary to make the statements therein not misleading, and the Company shall
promptly prepare a supplement or amendment to the Registration Statement to
correct such untrue statement or omission and deliver such number of copies of
such supplement or amendment to the Investor as reasonably requested by the
Investor.

                                    (vi) Except as provided in Section
5.2(b)(ii), the Company shall use its best efforts to prevent the issuance of
any stop order or other suspension of effectiveness of the Registration
Statement and, if such an order is issued, to obtain the withdrawal of such
order at the earliest practicable moment (including in each case by amending or
supplementing the Registration Statement). The Company shall promptly notify the
Investor of the issuance of any such order and the resolution thereof (and if
the Registration Statement is supplemented or amended, deliver such number of
copies of such supplement or amendment to the Investor as the Investor may
reasonably request).

                                       12

   13

                                    (vii) The Company shall give a single firm
of counsel designated by the Investor the opportunity to review the Registration
Statement and all amendments and supplements thereto a reasonable period of time
prior to their filing with the SEC, and not file any document in a form to which
such counsel reasonably objects in a timely fashion.

                                    (viii) At the request of the Investor, the
Company shall furnish, on the date of effectiveness of the Registration
Statement, an opinion, dated as of such date, from counsel representing the
Company addressed to the Investor and (1) in the case of an underwritten public
offering, in form, scope and substance as is customarily given in an
underwritten public offering, and (2) in all other cases, as mutually agreed by
the Company and the Investor.

                                    (ix) The Company shall hold in confidence
and not make any disclosure of information concerning the Investor provided to
the Company unless (A) disclosure of such information is necessary to comply
with federal or state securities laws, (B) the disclosure of such information is
necessary to avoid or correct a misstatement or omission in the Registration
Statement, (C) the release of such information is ordered pursuant to a subpoena
or other order from a court or governmental body of competent jurisdiction, (D)
such information has been made generally available to the public other than by
disclosure in violation of this or any other agreement, or (E) the Investor
consents to the form and content of any such disclosure. The Company agrees that
it shall, upon learning that disclosure of such information concerning the
Investor is sought in or by a court or governmental body of competent
jurisdiction or through other means, give prompt notice to the Investor prior to
making such disclosure, and allow the Investor, at its expense, to undertake
appropriate action to prevent disclosure of, or to obtain a protective order
for, such information.

                                    (x)     The Company shall promptly either 
(A) cause all of the Registrable Securities covered by the Registration
Statement to be listed on the NYSE, the AMEX or other national securities
exchange on which securities of the same class or series issued by the Company
are then listed, if any, if the listing of such Registrable Securities is then
permitted under the rules of such exchange, or (B) secure the designation and
quotation of all of the Registrable Securities covered by the Registration
Statement on the Nasdaq National Market and, without limiting the generality of
the foregoing, to arrange for or maintain at least two market makers to register
with the National Association of Securities Dealers ("NASD") as such with
respect to such Registrable Securities.

                                    (xi) The Company shall maintain a transfer
agent and registrar, which may be a single entity, for the Registrable
Securities not later than the effective date of the first Registration
Statement.

                                    (xii) The Company shall cooperate with the
Investor to facilitate the timely preparation and delivery of certificates (not
bearing any restrictive legends) representing Registrable Securities to be
offered pursuant to the Registration Statement and enable such certificates to
be in such denominations or amounts, as the case may be, as the Investor may
reasonably request and registered in such names as the Investor may request,
and, 
                                       13

   14

within five (5) business days after the Registration Statement is ordered
effective by the SEC, the Company shall deliver, and shall cause legal counsel
selected by the Company to deliver, to the transfer agent for the Registrable
Securities (with copies to the Investor) an opinion of such counsel as required
by the transfer agent prior to the transfer of the Registrable Securities.

                                    (xiii) At the request of the Investor, the
Company shall prepare and file with the SEC such amendments (including
post-effective amendments) and supplements to the Registration Statement and the
prospectus used in connection with the Registration Statement as may be
necessary in order to change the plan of distribution set forth in the
Registration Statement.

                                    (xiv) The Company shall comply with all
applicable laws related to the Registration Statement and the offering and sale
of securities thereunder and all applicable rules and regulations of
governmental authorities in connection therewith (including without limitation
the Securities Act and the Securities Exchange Act of 1934, as amended, and the
rules and regulations promulgated by the SEC).

                                    (xv) The Company shall take all such other
actions as the Investor reasonably requests in order to expedite or facilitate
the disposition of such Registrable Securities.

                                    (xvi) From and after the date of this
Agreement, the Company shall not, and shall not agree to, allow the holders of
any securities of the Company to include any of their securities in the
Registration Statement under Section 5.2(b)(i) hereof or any amendment or
supplement thereto under Section 5.2(c)(ii) hereof without the prior written
consent of the Investor. The foregoing shall not apply to the extent, and only
to the extent, that such holders are contractually entitled, as of the date of
this Agreement, to so include their securities in such Registration Statement or
amendment or supplement thereto; provided, however, that the Company shall use
its best efforts to cause such holders to waive their rights to be so included
(it being understood and agreed that the Company will not be required to seek a
waiver from America Online in this regard).

                           (d) Obligations of the Investor. In connection with
the registration of the Registrable Securities, the Investor shall have the
following obligations:

                                    (i)     It shall be a condition precedent to
the obligations of the Company to complete the registration pursuant to this
Agreement with respect to the Registrable Securities that the Investor shall
furnish to the Company such information regarding itself, the Registrable
Securities held by it and the intended method of disposition of the Registrable
Securities as shall be required to effect the registration of such Registrable
Securities and shall execute such documents in connection with such registration
as the Company may reasonably request. At least two (2) business days prior to
the first anticipated filing date of the Registration Statement, the Company
shall notify the Investor of the information the Company requires from the
Investor.

                                       14

   15

                                    (ii) The Investor, by its acceptance of the
Registrable Securities, agrees to cooperate with the Company as reasonably
requested by the Company in connection with the preparation and filing of the
Registration Statement hereunder.

                                    (iii) The Investor agrees that, upon receipt
of any notice from the Company of the happening of any event of the kind
described in Section 5.2(c)(vi) or 5.2(c)(vii), the Investor will immediately
discontinue disposition of Registrable Securities pursuant to the Registration
Statement covering such Registrable Securities until receipt by the Investor of
the copies of the supplemented or amended prospectus contemplated by Section
5.2(c)(vi) or 5.2(c)(vii) and, if so directed by the Company, the Investor shall
deliver to the Company (at the expense of the Company) or destroy (and deliver
to the Company a certificate of destruction) all copies in the Investor's
possession, of the prospectus covering such Registrable Securities current at
the time of receipt of such notice.

                                    (iv) The Investor agrees to comply with the
prospectus delivery requirements under the Securities Act in connection with the
Investor's sales of the Registrable Securities.

                                    (v)     The Investor agrees, for so long as
the Investor owns any Registrable Securities and upon request of the
underwriters managing any underwritten public offering of the Company's Common
Stock, to enter into a standard form of lock-up agreement (not to exceed ninety
(90) days) in connection with such offering, provided that all officers and
directors of the Company and all shareholders of the Company who hold at least
the same number of shares of Common Stock of the Company (including such shares
issuable upon exercise or conversion of exercisable or convertible securities)
as the number of shares of Registrable Securities then held by the Investor,
enter into the same form of lock-up agreement.

                           (e) Expenses of Registration. All reasonable expenses
incurred by the Company or the Investor in connection with registrations,
filings or qualifications pursuant to Sections 5.2(b) and 5.2(c) above,
including, without limitation, all registration, listing and qualifications
fees, printers and accounting fees, the fees and disbursements of counsel for
the Company, the fees and disbursements of one counsel selected by the Investor,
but not underwriting discounts and commissions, shall be borne by the Company.
In addition, the Company shall pay all of the Investor's reasonable costs and
expenses (including legal fees) incurred in connection with the enforcement of
the rights of the Investor hereunder. (f) Indemnification.

                                    (i)     To the extent permitted by law, the
Company will indemnify, hold harmless and defend (A) the Investor, and (B) the
directors, officers, partners, members, employees and agents of the Investor and
each person who controls the Investor within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act, if any, (each, an "Indemnified
Person"), against any joint or several losses, claims, damages, liabilities or
expenses (collectively, together with actions, proceedings or inquiries by any
regulatory or self-regulatory organization, whether commenced or threatened, in
respect thereof, "Claims") to which any of them may become subject insofar as
such Claims arise out of or are based upon: 


                                       15

   16

(A) any untrue statement or alleged untrue statement of a material fact in the
Registration Statement or the omission or alleged omission to state therein a
material fact required to be stated or necessary to make the statements therein
not misleading, (B) any untrue statement or alleged untrue statement of a
material fact contained in any preliminary prospectus if used prior to the
effective date of the Registration Statement, or contained in the final
prospectus related thereto (as amended or supplemented, if the Company files any
amendment thereof or supplement thereto with the SEC) or the omission or alleged
omission to state therein any material fact necessary to make the statements
made therein, in light of the circumstances under which the statements therein
were made, not misleading, or (C) any violation or alleged violation by the
Company of the Securities Act, the Exchange Act, any other law, including,
without limitation, any state securities law, or any rule or regulation
thereunder relating to the offer or sale of the Registrable Securities (the
matters in the foregoing clauses (A) through (C) being, collectively,
"Violations"). Subject to the restrictions set forth in Section 5.2(f)(iii) with
respect to the number of legal counsel, the Company shall reimburse the Investor
and each other Indemnified Person, promptly as such expenses are incurred and
are due and payable, for any reasonable legal fees or other reasonable expenses
incurred by them in connection with investigating or defending any such Claim.
Notwithstanding anything to the contrary contained herein, the indemnification
agreement contained in this Section 5.2(f)(i): (A) shall not apply to a Claim
arising out of or based upon a Violation which occurs in reliance upon and in
conformity with information furnished in writing to the Company by such
Indemnified Person expressly for use in the Registration Statement or any such
amendment thereof or supplement thereto; (B) shall not apply to amounts paid in
settlement of any Claim if such settlement is effected without the prior written
consent of the Company, which consent shall not be unreasonably withheld; and
(C) with respect to any preliminary prospectus, shall not inure to the benefit
of any Indemnified Person if the untrue statement or omission of material fact
contained in the preliminary prospectus was corrected on a timely basis in the
prospectus, as then amended or supplemented, if such corrected prospectus was
timely made available by the Company pursuant to Section 5.2(c)(iii) hereof, and
the Indemnified Person was promptly advised in writing not to use the incorrect
prospectus prior to the use giving rise to a Violation and such Indemnified
Person, notwithstanding such advice, used it. Such indemnity shall remain in
full force and effect regardless of any investigation made by or on behalf of
the Indemnified Person.

                                    (ii) The Investor agrees to indemnify, hold
harmless and defend, to the same extent and in the same manner set forth in
Section 5.2(f)(i), the Company, each of its directors, each of its officers who
signs the Registration Statement, its employees, agents and each person, if any,
who controls the Company within the meaning of Section 15 of the Securities Act
or Section 20 of the Exchange Act (collectively and together with an Indemnified
Person, an "Indemnified Party"), against any Claim to which any of them may
become subject, under the Securities Act, the Exchange Act or otherwise, insofar
as such Claim arises out of or is based upon any Violation, in each case to the
extent (and only to the extent) that such Violation occurs in reliance upon and
in conformity with written information furnished to the Company by the Investor
expressly for use in connection with the Registration Statement; and subject to
Section 5.2(f)(iii), the Investor will reimburse any legal or other expenses
(promptly as such expenses are incurred and are due and payable) reasonably
incurred by them in connection with investigating or defending any such Claim;
provided, however, that the 


                                       16

   17

indemnity agreement contained in this Section 5.2(f)(ii) shall not apply to
amounts paid in settlement of any Claim if such settlement is effected without
the prior written consent of the Investor, which consent shall not be
unreasonably withheld; provided, further, however, that the Investor shall be
liable under this Agreement (including this Section 5.2(f)(ii) and Section
5.2(g)) for only that amount as does not exceed the net proceeds actually
received by the Investor as a result of the sale of Registrable Securities
pursuant to the Registration Statement. Such indemnity shall remain in full
force and effect regardless of any investigation made by or on behalf of such
Indemnified Party and shall survive the transfer of the Registrable Securities
by the Investor. Notwithstanding anything to the contrary contained herein, the
indemnification agreement contained in this Section 5.2(f)(ii) shall not inure
to the benefit of any Indemnified Party (i) with respect to any preliminary
prospectus if the untrue statement or omission of material fact contained in the
preliminary prospectus was corrected on a timely basis in the final prospectus,
as then amended or supplemented, and the Indemnified Party failed to utilize
such corrected prospectus, or (ii) with respect to any liability arising from
the failure to deliver any prospectus if the Indemnified Party failed to deliver
such prospectus as required under the Securities Act.

                                    (iii) Promptly after receipt by an
Indemnified Person or Indemnified Party under this Section 5.2(f) of notice of
the commencement of any action (including any governmental action), such
Indemnified Person or Indemnified Party shall, if a Claim in respect thereof is
to made against any indemnifying party under this Section 5.2(f), deliver to the
indemnifying party a written notice of the commencement thereof, and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume control of the defense thereof with counsel
mutually satisfactory to the indemnifying party and the Indemnified Person or
the Indemnified Party, as the case may be; provided, however, that such
indemnifying party shall not be entitled to assume such defense and an
Indemnified Person or Indemnified Party shall have the right to retain its own
counsel with the fees and expenses to be paid by the indemnifying party, if, in
the reasonable opinion of counsel retained by the indemnifying party, the
representation by such counsel of the Indemnified Person or Indemnified Party
and the indemnifying party would be inappropriate due to actual or potential
conflicts of interest between such Indemnified Person or Indemnified Party and
any other party represented by such counsel in such proceeding or the actual or
potential defendants in, or targets of, any such action include both the
Indemnified Person or the Indemnified Party and the indemnifying party and any
such Indemnified Person or Indemnified Party reasonably determines that there
may be legal defenses available to such Indemnified Person or Indemnified Party
which are in conflict with those available to such indemnifying party. The
indemnifying party shall pay for only one separate legal counsel for the
Indemnified Persons or the Indemnified Parties, as applicable, and such legal
counsel shall be selected by the Investor, if the Investor is entitled to
indemnification hereunder, or by the Company, if the Company is entitled to
indemnification hereunder, as applicable. The failure to deliver written notice
to the indemnifying party within a reasonable time after the commencement of any
such action shall not relieve such indemnifying party of any liability to the
Indemnified Person or Indemnified Party under this Section 5.2(f), except to the
extent that the indemnifying party is actually prejudiced in its ability to
defend such action. The indemnification required by this Section 5.2(f) shall be
made by periodic payments of the amount 


                                       17

   18

thereof during the course of the investigation or defense, as such expense,
loss, damage or liability is incurred and is due and payable.

                           (g) Reports Under the Exchange Act.  With a view to
making available to the Investor the benefits of Rule 144 promulgated under the
Securities Act or any other similar rule or regulation of the SEC that may at
any time permit the Investor to sell securities of the Company to the public
without registration ("Rule 144"), the Company agrees to:

                                    (i)     file with the SEC in a timely manner
and make and keep available all reports and other documents required of the
Company under the Securities Act and the Exchange Act so long as the Company
remains subject to such requirements and the filing and availability of such
reports and other documents is required for the applicable provisions of Rule
144; and
