a Common Stock Purchase Agreement by and between Edison Venture IV and Sonny
Hunt, a founder of the Issuer (the "Common Purchase Agreement"), pursuant to
which Edison Venture IV agreed to acquire a number of shares of Common Stock
from Sonny Hunt. Both agreements contemplated a potential second closing,
contingent upon approval of the shareholders of the Issuer with respect to the
issuance of the securities to be sold at such second closing. Pursuant to these
two agreements, Edison Venture IV acquired the following on the First Closing
Date:

           a)   456,169 shares of Common Stock (the "First Closing Common
                Shares") pursuant to the Common Purchase Agreement for an
                aggregate purchase price of $228,085;

           b)   2,088,684 shares of the Preferred Stock (the "First Closing
                Preferred Shares") pursuant to the Preferred Purchase Agreement
                for an aggregate purchase price of $1,900,702; and

           c)   a warrant to purchase up to 522,171 shares of Common Stock (the
                "First Closing Warrant") from the Issuer, either currently
                exercisable or exercisable within 60 days of September 5, 2001,
                for an aggregate purchase price of $5,222.

          On November 14, 2001 (the "Second Closing Date"), the Issuer having
obtained the requisite shareholder approval, there was a second closing pursuant
to the terms of the Preferred Purchase Agreement and the Common Purchase
Agreement.

         On the Second Closing Date, Edison Venture IV acquired the Following:

           (a)  143,831 shares of Common Stock (the "Second Closing Common
                Shares" and together with the First Closing Common Shares, the
                "Common Shares") pursuant to the Common Purchase Agreement, for
                an aggregate purchase price of $71,916;

thereunder has been taken. Each of this Agreement and the Other Documents has

               (b) Purchase Entirely for Own Account. This Agreement is made

securities of companies in the development stage and acknowledges that it is
able to fend for itself, can bear the economic risk of its investment
indefinitely and has such knowledge and experience in financial and business
matters that it its capable of evaluating the merits and risks of its investment
in the Series A Preferred Shares. Such Purchaser also represents it has not been
organized for the purpose of acquiring the Series A Preferred Shares. Such

               (e) Restricted Securities. Such Purchaser understands that the
Series A Preferred Shares and the Converted Shares it is purchasing are
characterized as "restricted securities" under the federal securities laws
inasmuch as they are being acquired from the Company in a transaction not
involving a public offering and that under such laws and applicable regulations
such securities may be resold without registration under the Securities Act,
only in certain limited circumstances. In this connection, such Purchaser
represents that it is familiar with SEC Rule 144, as currently in effect, and
understands the resale limitations imposed thereby and by the Securities Act.

the Company's business, management and financial affairs with directors,
officers and management of the Company and has had the opportunity to review the
Company's operations and facilities. Each Purchaser has also had the opportunity
to ask questions of, and receive answers from, the Company and its management
regarding the terms and conditions of this investment.

Purchaser resides in the state or province identified in the address of the

address or addresses of the Purchaser set forth on Exhibit 1.01.

               (h) Brokers' Fees. No Purchaser has taken any action which would
give rise to any claim by any other person for any brokerage commissions,
finders' fees or the like relating to this Agreement or the transactions
contemplated hereby.

               (i) Securities Act Restrictions. The acquisition by each
Purchaser of the Series A Preferred Shares and the Warrants acquired by it shall
constitute a confirmation of the representations and warranties made by each
such Purchaser as at the date of such acquisition. Each of the Purchasers
further represents that it understands and agrees that, until registered


        Series A Convertible Preferred Stock Purchase Agreement -- Page 5

under the Securities Act of 1933, as amended (the "Securities Act") or
transferred pursuant to the provisions of Rule 144 as promulgated by the
Securities and Exchange Commission (the "SEC"), all certificates evidencing any
of the Shares or the Warrants shall bear a legend, prominently stamped or
printed thereon, reading substantially as follows:

         "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
         REGISTERED UNDER THE SECURITIES ACT OF 1933 OR APPLICABLE STATE
         SECURITIES LAWS. THESE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND
         NOT WITH A VIEW TO DISTRIBUTION OR RESALE, AND MAY NOT BE SOLD,

         SECURITIES LAWS, OR UPON RECEIPT BY THE COMPANY OF AN OPINION OF
         COUNSEL SATISFACTORY TO THE COMPANY THAT REGISTRATION IS NOT REQUIRED
         FOR SUCH SALE, TRANSFER OR ASSIGNMENT."

         1.08. Purchase Price Allocation. The Company and the Purchasers having
adverse interests and as a result of arm's length bargaining, agree that (i)
neither the Purchasers nor any of their partners, members or employees has
rendered or has agreed to render any services to the Company in connection with
this Agreement or the issuance of Warrants; (ii) the Warrants are not being
issued as compensation; and (iii) for the purpose, and within the meaning, of
Section 1273(c)(2) of the Internal Revenue Code of 1986, as amended (the
"Code"), the issue price of the Warrants is $0.01 per Warrant Share. The Company
and the Purchasers acknowledge that this allocation is based on the relative
fair market values of the Preferred Shares and Warrants. The Company and the
Purchasers recognize that this Agreement determines the original issue discount
to be taken into account by the Company and the Purchasers for federal income
tax purposes and they agree to adhere to this Agreement for such purposes.

reorganizations, transactions under Rule 145 of the Securities Act or
registration statements on Forms S-4, S-8 or another form not available for
registering the Restricted Stock for sale to the public), each such time it will
give written notice to all holders of outstanding Restricted Stock of its
intention so to do. Upon the written request of any such holder, received by the
Company within 30 days after the giving of any such notice by the Company,


                       Investor Rights Agreement - Page 4

to register any of its Restricted Stock, the Company will use its best efforts
to cause the Restricted Stock as to which registration shall have been so
requested to be included in the securities to be covered by the registration
statement proposed to be filed by the Company, all to the extent requisite to
permit the sale or other disposition by the holder of such Restricted Stock so
registered. In the event that any registration pursuant to this Section 5 shall
be, in whole or in part, an underwritten public offering of Common Stock, the
number of shares of Restricted Stock to be included in such an underwriting may
be reduced (PRO RATA among the requesting holders based upon the number of
shares of Restricted Stock owned by such holders) if and to the extent that the
managing underwriter shall be of the opinion that such inclusion would
materially adversely affect the offering price of the securities to be sold by
the Company therein, PROVIDED, HOWEVER, that such number of shares of Restricted
Stock shall not be reduced until all shares to be included in such underwriting
for the account of any person other than the Company and the requesting holders
of Restricted Stock are first excluded, and PROVIDED, FURTHER, HOWEVER, that in
no event may less than twenty percent (20%) of the total number of shares of
Common Stock to be included in such underwriting be made available for shares of
Restricted Stock unless all other shares are first excluded from such offering
and the managing underwriter shall in good faith advise the holders proposing to
distribute their securities through such underwriting that such level of
participation would, in its opinion, materially adversely affect the offering
price and its ability to complete the offering and shall specify the number of
shares of Restricted Stock which, in its opinion, can be included in the
registration and underwriting without such an effect. The Company shall have the
right to terminate or withdraw any registration initiated by it under this
Section 5 prior to the effectiveness of such registration whether or not any
holder of Restricted Stock has elected to include securities in such
registration. The registration expenses of such withdrawn registration shall be
borne by the Company in accordance with Section 7 hereof.

         6. Registration on Form S-3.

               (a) If at any time (i) a holder or holders of Restricted Stock
request that the Company file a registration statement on Form S-3 or any
successor thereto for a public offering of all or any portion of the shares of
Restricted Stock held by such requesting holder or holders which has an
anticipated aggregate price to the public (prior to underwriters commissions and
discounts) that would exceed $1,000,000, and (ii) the Company is a registrant
entitled to use Form S-3 or any successor thereto to register such shares, then
the Company shall use its best efforts to register under the Securities Act on
Form S-3 or any successor thereto, for public sale in accordance with the method
of disposition specified in such notice, the number of shares of Restricted
Stock specified in such notice.

               (b) Following receipt of any notice under this Section 6, the
Company shall immediately notify all holders of Restricted Stock and Preferred
Shares from whom notice has not been received and such holders shall then be
entitled within 30 days thereafter to request the Company to include in the
requested registration all or any portion of their shares of Restricted Stock.
The Company shall use its best efforts to register under the Securities Act, for
public sale in accordance with the method of disposition described in paragraph
(a) above, the number of shares of Restricted Stock specified in such notice
(and in all notices received by the Company from other holders within 30 days
after the giving of such notice by the Company).


                       Investor Rights Agreement - Page 5

               (c) The Company shall be entitled to include in any registration
statement referred to in this Section 6 shares of Common Stock to be sold by the
Company for its own account, except as and to the extent that, in the opinion of
the managing underwriter, such inclusion would adversely affect the marketing of
the Restricted Stock to be sold. No other shares may be included in such
registration statement. Except for registration statements on Form S-4, S-8 or
any successor thereto, the Company will not file with the Commission any other
registration statement with respect to its Common Stock, whether for its own
account or that of other shareholders, from the date of receipt of a notice from
requesting holders requesting sale pursuant to an underwritten offering pursuant
to this Section 6 until the completion of the period of distribution of the
registration contemplated thereby.

               (d) If in the opinion of the managing underwriter the inclusion
of all of the Restricted Stock requested to be registered under this Section 6
would adversely affect the marketing of such shares, shares to be sold by the
holders of Restricted Stock, if any, shall be excluded only after any shares to
be sold by the Company have been excluded, in such manner that the shares to be
sold shall be allocated among the selling holders PRO RATA based on their
ownership of Restricted Stock.

Notwithstanding anything to the contrary in this Section 6, the Company shall
not be required to effect any such registration, qualification or compliance
pursuant to this Section 6:

                  (i) if the Company has, within the six month period preceding
         the date of such request, already effected a registration on Form S-3
         for the holders of Restricted Stock pursuant to this Section 6;

                  (ii) if the Company shall furnish to the holders of Restricted
         Stock a certificate signed by the Chairman of the Board stating that in
         the good faith judgment of the Board of Directors, there exists at the
         time material non-public information relating to the Company the
         disclosure of which would be required in such registration statement,
         and which disclosure would be seriously detrimental to the Company and
         its shareholders, in which event the Company shall have the right to
         defer the filing of the Form S-3 registration statement for a period of
         not more than ninety (90) days after receipt of the request of the
         holders of Restricted Stock under this Section 6; provided, that such
         right to delay a request shall be exercised by the Company not more
         than once in any twelve month period;

                  (iii) in any particular jurisdiction in which the Company
         would be required to execute a general consent to service of process in
         effecting such registration, qualification or compliance (provided the
         Company has not already executed such a consent or is already qualified
         to do business in such jurisdiction).

         7. Registration Procedures. If and whenever the Company is required by
the provisions of Sections 5 or 6 to use its best efforts to effect the
registration of any shares of Restricted Stock under the Securities Act, the
Company will, as expeditiously as possible:


                       Investor Rights Agreement - Page 6

               (a) prepare and file with the Commission a registration statement
with respect to such securities and use its commercially reasonable efforts to
cause such registration statement to become and remain effective for the period
of the distribution contemplated thereby (determined as hereinafter provided);

               (b) prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective for
the period specified in paragraph (a) above and comply with the provisions of
the Securities Act with respect to the disposition of all Restricted Stock
covered by such registration statement in accordance with the sellers' intended
method of disposition set forth in such registration statement for such period;

               (c) furnish to each seller of Restricted Stock and to each
underwriter such number of copies of the registration statement and the
prospectus included therein (including each preliminary prospectus) as such
persons reasonably may request in order to facilitate the public sale or other
disposition of the Restricted Stock covered by such registration statement;

               (d) use its commercially reasonable efforts to register or
qualify the Restricted Stock covered by such registration statement under the
securities or "blue sky" laws of such jurisdictions as the sellers of Restricted
Stock or, in the case of an underwritten public offering, the managing
underwriter reasonably shall request, PROVIDED, HOWEVER, that the Company shall
not for any such purpose be required to qualify generally to transact business
as a foreign corporation in any jurisdiction where it is not so qualified or to
consent to general service of process in any such jurisdiction;

               (e) use its commercially reasonable efforts to list the
Restricted Stock covered by such registration statement with any securities
exchange on which the Common Stock of the Company is then listed;

               (f) provide a transfer agent and registrar for all such
Restricted Stock, not later than the effective date of such registration
statement;

               (g) immediately notify each seller of Restricted Stock and each
underwriter under such registration statement, at any time when a prospectus
relating thereto is required to be delivered under the Securities Act, of the
happening of any event of which the Company has knowledge as a result of which
the prospectus contained in such 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 in light of the circumstances then existing. The holders of
Restricted Stock covered by such registration statement agree upon receipt of
such notice forthwith to cease making offers and sales of Restricted Stock
pursuant to such registration statement or deliveries of the prospectus
contained therein for any purpose until the Company has prepared and furnished
such amendment or supplement to the prospectus as may be necessary so that, as
thereafter delivered to purchasers of such Restricted Stock, such prospectus
shall not include 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 not misleading in the light of the circumstances then existing. The
Company shall use


                       Investor Rights Agreement - Page 7

best efforts to prepare and furnish such amendment or supplement to the
prospectus within a commercially reasonable period of time;

               (h) use its best efforts to furnish on the date that such
Restricted Stock is delivered to the underwriters for sale, if such securities
are being sold through underwriters: (i) an opinion, dated such date, of the
counsel representing the Company for the purposes of such registration, in form
and substance as is customarily given to underwriters in an underwritten public
offering, addressed to the underwriters and to such seller and (ii) a letter
dated as of such date from the independent certified public accountants of the
Company, in form and substance as is customarily given by the independent
certified public accountants to underwriters in an underwritten public offering
addressed to the underwriters and to such seller;

               (i) make available for inspection by each seller of Restricted
Stock, any underwriter participating in any distribution pursuant to such
registration statement, and any attorney, accountant or other agent retained by
such seller or underwriter, all financial and other records, pertinent corporate
documents and properties of the Company, and cause the Company's officers,
directors and employees to supply all information reasonably requested by any
such seller, underwriter, attorney, accountant or agent in connection with such
registration statement, except that the Company may refuse to provide such
information or access to any person that the Board of Directors reasonably
concludes is a competitor of the Company;

               (j) advise each selling holder of Restricted Stock, promptly
after it shall receive notice or obtain knowledge thereof, of the issuance of
any stop order by the Commission suspending the effectiveness of such
registration statement or the initiation or threatening of any proceeding for
such purpose and promptly use all reasonable efforts to prevent the issuance of
any stop order or to obtain its withdrawal if such stop order should be issued;

               (k) cooperate with the selling holders of Restricted Stock and
the managing underwriters, if any, to facilitate the timely preparation and
delivery of certificates representing Restricted Stock to be sold, such
certificates to be in such denominations and registered in such names as such
holders or the managing underwriters may request at least two business days
prior to any sale of Restricted Stock; and

               (l) permit Edison Venture Fund IV, L.P. ("Edison") or any
affiliate or limited partner of Edison that is a holder of Restricted Stock
which holder, in the sole and exclusive judgment, exercised in good faith, of
such holder, might be deemed to be a controlling person of the Company, to
participate in good faith in the preparation of such registration or comparable
statement and to require the insertion therein of material, furnished to the
Company in writing, which in the reasonable judgment of such holder and its
counsel should be included, subject to review by the Company and its counsel
after consultation with such holder.

         For purposes of Section 7(a) and 7(b) and of Section 6(c), the period
of distribution of Restricted Stock in a firm commitment underwritten public
offering shall be deemed to extend until each underwriter has completed the
distribution of all securities purchased by it, and the period of distribution
of Restricted Stock in any other registration shall be deemed to extend until


                       Investor Rights Agreement - Page 8

the earlier of the sale of all Restricted Stock covered thereby and 120 days
after the effective date thereof.

         In connection with each registration hereunder, the sellers of
Restricted Stock will furnish to the Company in writing such information with
respect to themselves and the proposed distribution by them as reasonably shall
be necessary in order to assure compliance with federal and applicable state
securities laws.

         In connection with each registration pursuant to Sections 5 or 6
covering an underwritten public offering, the Company and each seller agree to
enter into a written agreement with the managing underwriter selected in the
manner herein provided in such form and containing such provisions as are
customary in the securities business for such an arrangement between such
underwriter and companies of the Company's size and investment stature.

         8. Assignment of Registration Rights. The registration rights of
holders of Restricted Stock pursuant to Sections 5 and 6 hereof may be assigned
by a holder to a transferee or assignee of Restricted Stock which (a) is a
subsidiary, parent, general partner, limited partner, retired partner, member,
retired member or affiliate of such holder, (b) is a holder's immediate family
member or a trust for the benefit of an individual holder or immediate family
members, or (c) acquires at least 25% of the Restricted Stock held by the
transferring holder (as adjusted for stock splits and the like); PROVIDED,
HOWEVER, (i) the transferor shall, within ten (10) days after such transfer,
furnish to the Company written notice of the name and address of such transferee
or assignee and the securities with respect to which such registration rights
are being assigned, and (ii) such transferee shall agree to be subject to all
restrictions set forth in this Agreement.

         9. Expenses. All expenses incurred by the Company in complying with
Sections 5 and 6, including, without limitation, all registration and filing
fees, printing expenses, fees and disbursements of counsel and independent
public accountants for the Company, fees and expenses (including counsel fees)
incurred in connection with complying with state securities or "blue sky" laws,
fees of the National Association of Securities Dealers, Inc., transfer taxes,
fees of transfer agents and registrars, costs of insurance, and fees and
disbursements of one counsel for the sellers of Restricted Stock, but excluding
any Selling Expenses, are called "Registration Expenses". All underwriting
discounts and selling commissions applicable to the sale of Restricted Stock are
called "Selling Expenses". The Company shall not, however, be required to pay
for Registration Expenses regarding any registration proceeding begun pursuant
to Section 6, the request of which has been subsequently withdrawn by the
holders of Restricted Stock making such request (and such holders will indemnify
the Company against all such reasonable Registration Expenses) unless (a) the
withdrawal is based upon material adverse information concerning the Company
(including a material drop in the market price of the Company's Common Stock) of
which such holders of Restricted Stock were not aware at the time of such
request, or (b) such holders of Restricted Stock agree to forfeit their right to
one requested registration pursuant to Section 6, in which event such right
shall be forfeited by all holders of Restricted Stock. If the holders of
Restricted Stock are required to pay the Registration Expenses, such expenses
shall be borne by the holders of securities (including Restricted Stock)
requesting such registration in proportion to the number of shares for which
registration was requested.


                       Investor Rights Agreement - Page 9

         The Company will pay all Registration Expenses in connection with each
registration statement under Sections 5 or 6. All Selling Expenses in connection
with each registration statement under Sections 5 or 6 shall be borne by the
participating sellers in proportion to the number of shares sold by each, or by
such participating sellers other than the Company (except to the extent the
Company shall be a seller) as they may agree.

         10. Indemnification and Contribution.

               (a) In the event of a registration of any of the Restricted Stock
under the Securities Act pursuant to Sections 5 or 6, the Company will indemnify
and hold harmless each seller of such Restricted Stock thereunder, each
underwriter of such Restricted Stock thereunder and each other person, if any,
who controls such seller or underwriter within the meaning of the Securities
Act, against any losses, claims, damages or liabilities, joint or several, to
which such seller, underwriter or controlling person may become subject under
the Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
any registration statement under which such Restricted Stock was registered
under the Securities Act pursuant to Sections 5 or 6, any preliminary prospectus
or final prospectus contained therein, or any amendment or supplement thereof,
or arise out of or are based upon the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, and will reimburse each such seller, each
such underwriter and each such controlling person for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action, PROVIDED, HOWEVER,
that the indemnity agreement contained in this Section 10(a) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or action
if such settlement is effected without the consent of the Company; and PROVIDED,
FURTHER, HOWEVER, that the Company will not be liable in any such case if and to
the extent that any such loss, claim, damage or liability arises out of or is
based upon an untrue statement or alleged untrue statement or omission or
alleged omission so made in conformity with information furnished by any such
seller (or such seller's partner, officer, director, or controlling person), any
such underwriter or any such controlling person in writing specifically for use
in such registration statement or prospectus.

               (b) In the event of a registration of any of the Restricted Stock
under the Securities Act pursuant to Sections 5 or 6, each seller of such
Restricted Stock thereunder, severally and not jointly, will indemnify and hold
harmless the Company, each person, if any, who controls the Company within the
meaning of the Securities Act, each officer of the Company who signs the
registration statement, each director of the Company, each underwriter and each
person who controls any underwriter within the meaning of the Securities Act,
against all losses, claims, damages or liabilities, joint or several, to which
the Company or such officer, director, underwriter or controlling person may
become subject under the Securities Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon any untrue statement or alleged untrue statement of any material
fact contained in the registration statement under which such Restricted Stock
was registered under the Securities Act pursuant to Sections 5 or 6, any
preliminary prospectus or final prospectus contained therein,


                       Investor Rights Agreement - Page 10

or any amendment or supplement thereof, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
will reimburse the Company and each such officer, director, underwriter and
controlling person for any legal or other expenses reasonably incurred by them
in connection with investigating or defending any such loss, claim, damage,
liability or action, PROVIDED, HOWEVER, that the indemnity agreement contained
in this Section 10(b) shall not apply to amounts paid in settlement of any such
loss, claim, damage, liability or action if such settlement is effected without
the consent of the each seller; PROVIDED, FURTHER, HOWEVER that such seller will
be liable hereunder in any such case if and only to the extent that any such
loss, claim, damage or liability arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission made in
reliance upon and in conformity with information pertaining to such seller, as
such, furnished in writing to the Company by such seller specifically for use in
such registration statement or prospectus, and PROVIDED, FINALLY, HOWEVER, that
the liability of each seller hereunder shall be limited to the net proceeds
received by such seller from the sale of Restricted Stock covered by such
registration statement.

               (c) Promptly after receipt by an indemnified party hereunder of
notice of the commencement of any action, such indemnified party shall, if a
claim in respect thereof is to be made against the indemnifying party hereunder,
notify the indemnifying party in writing thereof, but the omission so to notify
the indemnifying party shall not relieve it from any liability which it may have
to such indemnified party other than under this Section 10 and shall only
relieve it from any liability which it may have to such indemnified party under
this Section 10 if and to the extent the indemnifying party is prejudiced by
such omission. In case any such action shall be brought against any indemnified
party and it shall notify the indemnifying party of the commencement thereof,
the indemnifying party shall be entitled to participate in and, to the extent it
shall wish, to assume and undertake the defense thereof with counsel reasonably
satisfactory to such indemnified party, and, after notice from the indemnifying
party to such indemnified party of its election so to assume and undertake the
defense thereof, the indemnifying party shall not be liable to such indemnified
party under this Section 10 for any legal expenses subsequently incurred by such
indemnified party in connection with the defense thereof other than reasonable
costs of investigation and of liaison with counsel so selected, PROVIDED,
HOWEVER, that, if the defendants in any such action include both the indemnified
party and the indemnifying party and the indemnified party shall have reasonably
concluded that there may be reasonable defenses available to it which are
different from or additional to those available to the indemnifying party or if
the interests of the indemnified party reasonably may be deemed to conflict with
the interests of the indemnifying party, the indemnified party shall have the
right to select a separate counsel and to assume such legal defenses and
otherwise to participate in the defense of such action, with the expenses and
fees of such separate counsel and other expenses related to such participation
to be reimbursed by the indemnifying party as incurred.

               (d) In order to provide for just and equitable contribution to
joint liability under the Securities Act in any case in which either (i) any
holder of Restricted Stock exercising rights under this Agreement, or any
controlling person of any such holder, makes a claim for indemnification
pursuant to this Section 10 but it is judicially determined (by the entry of a
final judgment or decree by a court of competent jurisdiction and the expiration
of time to appeal or


                       Investor Rights Agreement - Page 11

the denial of the last right of appeal) that such indemnification may not be
enforced in such case notwithstanding the fact that this Section 10 provides for
indemnification in such case, or (ii) contribution under the Securities Act may
be required on the part of any such selling holder or any such controlling
person in circumstances for which indemnification is provided under this Section
10; then, and in each such case, the Company and such holder will contribute to
the aggregate losses, claims, damages or liabilities to which they may be
subject (after contribution from others) in such proportion so that such holder
is responsible for the portion represented by the percentage that the public
offering price of its Restricted Stock offered by the registration statement
bears to the public offering price of all securities offered by such
registration statement, and the Company is responsible for the remaining
portion; PROVIDED, HOWEVER, that, in any such case, (A) no such holder will be
required to contribute any amount in excess of the public offering price of all
such Restricted Stock offered by it pursuant to such registration statement; and
(B) no person or entity guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) will be entitled to contribution
from any person or entity who was not guilty of such fraudulent
misrepresentation.

               (e) The obligations of the Company and holders of Restricted
Stock under this Section 10 shall survive completion of any offering which
includes Restricted Stock in a registration statement and the termination of
this Agreement. No indemnifying party, in the defense of any such claim or
litigation, shall, except with the consent of each indemnified party, consent to
the entry of any judgment or enter into any settlement which does not include as
an unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of a general release from all liability in respect to such
claim or litigation.

         11. Changes in Common Stock or Preferred Stock. If, and as often as,
there is any change in the Common Stock or the Preferred Stock by way of a stock
split, stock dividend, combination or reclassification, or through a merger,
consolidation, reorganization or recapitalization, or by any other means,
appropriate adjustment shall be made in the provisions hereof so that the rights
and privileges granted hereby shall continue with respect to the Common Stock
and the Preferred Stock as so changed.

         12. Rule 144 Reporting. With a view to making available the benefits of
certain rules and regulations of the Commission which may at any time permit the
sale of the Restricted Stock to the public without registration, at all times
after 90 days after any registration statement covering a public offering of
securities of the Company under the Securities Act shall have become effective,
the Company agrees to:

               (a) make and keep public information available, as those terms
are understood and defined in Rule 144 under the Securities Act;

               (b) use its best efforts to file with the Commission in a timely
manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act; and

               (c) so long as a holder owns any Restricted Stock, furnish to
each holder of Restricted Stock forthwith upon request a written statement by
the Company as to its compliance


                       Investor Rights Agreement - Page 12

with the reporting requirements of such Rule 144 and of the Securities Act and
the Exchange Act, a copy of the most recent annual or quarterly report of the
Company, and such other reports and documents so filed by the Company as such
holder may reasonably request in availing itself of any rule or regulation of
the Commission allowing such holder to sell any Restricted Stock without
registration.

         13.  Right of First Refusal

               (a) Right of First Refusal. The Company shall not issue, sell or
exchange, agree or obligate itself to issue, sell or exchange any (i) shares of
Common Stock, (ii) any other equity security of the Company, including without
limitation, Preferred Shares, (iii) any debt security of the Company (other than
debt with no equity feature) including without limitation, any debt security
which by its terms is convertible into or exchangeable for any equity security
of the Company, (iv) any security of the Company that is a combination of debt
and equity, or (v) any option, warrant or other right to subscribe for, purchase
or otherwise acquire any such equity security or any such debt security of the
Company, unless in each case the Company shall have first offered to sell such
securities (the "Offered Securities") to the Investors (each an "Offeree" and
collectively, the "Offerees") as follows: Each Offeree shall have the right to
purchase (x) that portion of the Offered Securities as the number of shares of
Restricted Stock then held by such Offeree bears to the total number of shares
of Restricted Stock held on such date by all Offerees (the "Basic Amount"), and
(y) such additional portion of the Offered Securities as such Offeree shall
indicate it will purchase should the other Offerees subscribe for less than
their Basic Amounts (the "Undersubscription Amount"), at a price and on such
other terms as shall have been specified by the Company in writing delivered to
such Offeree (the "Offer"), which Offer by its terms shall remain open and
irrevocable for a period of twenty (20) days from receipt of the offer.

               (b) Notice of Acceptance. Notice of each Offeree's intention to
accept, in whole or in part, any Offer made pursuant to Section 13(a) shall be
evidenced by a writing signed by such Offeree and delivered to the Company prior
to the end of the 20-day period of such offer, setting forth such of the
Offeree's Basic Amount as such Offeree elects to purchase and, if such Offeree
shall elect to purchase all of its Basic Amount, such Undersubscription Amount
as such Offeree shall elect to purchase (the "Notice of Acceptance"). If the
Basic Amounts subscribed for by all Offerees are less than the total Offered
Securities, then each Offeree who has set forth Undersubscription Amounts in its
Notice of Acceptance shall be entitled to purchase, in addition to the Basic
Amounts subscribed for, all Undersubscription Amounts it has subscribed for;
PROVIDED, HOWEVER, that should the Undersubscription Amounts subscribed for
exceed the difference between the Offered Securities and the Basic Amounts
subscribed for (the "Available Undersubscription Amount"), each Offeree who has
subscribed for any Undersubscription Amount shall be entitled to purchase only
that portion of the Available Undersubscription Amount as the Undersubscription
Amount subscribed for by such Offeree bears to the total Undersubscription
Amounts subscribed for by all Offerees, subject to rounding by the Board of
Directors to the extent it reasonably deems necessary.


                       Investor Rights Agreement - Page 13

               (c) Conditions to Acceptances and Purchase.

                   (i) Permitted Sales of Refused Securities. In the event that
Notices of Acceptance are not given by the Offerees in respect of all the
Offered Securities, the Company shall have ninety (90) days from the expiration
of the period set forth in Section 13(a) to close the sale of all or any part of
such Offered Securities as to which a Notice of Acceptance has not been given by
the Offerees (the "Refused Securities") to the Person or Persons specified in
the Offer, but only in all respects upon terms and conditions, including,
without limitation, unit price and interest rates, which are no more favorable,
in the aggregate, to such other Person or Persons or less favorable to the
Company than those set forth in the Offer.

                   (ii) Reduction in Amount of Offered Securities. In the event
the Company shall propose to sell less than all the Refused Securities (any such
sale to be in the manner and on the terms specified in Section 13(c)(i) above),
then each Offeree may, at its sole option and in its sole discretion, reduce the
number of, or other units of the Offered Securities specified in its respective
Notices of Acceptance to an amount which shall be not less than the amount of
the Offered Securities which the Offeree elected to purchase pursuant to Section
13(b) multiplied by a fraction, (i) the numerator of which shall be the amount
of Offered Securities which the Company actually proposes to sell, and (ii) the
denominator of which shall be the amount of all Offered Securities. In the event
that any Offeree so elects to reduce the number or amount of Offered Securities
specified in its respective Notices of Acceptance, the Company may not sell or
otherwise dispose of more than the reduced amount of the Offered Securities
until such securities have again been offered to the Offerees in accordance with
Section 13(a).

                   (iii) Closing. Upon the closing of the sale to such other
Person or Persons of all or less than all the Refused Securities, the Offerees
shall purchase from the Company, and the Company shall sell to the Offerees, the
number of Offered Securities specified in the Notices of Acceptance, as reduced
pursuant to Section 13(c)(ii) if the Offerees have so elected, upon the terms
and conditions specified in the Offer. The purchase by the Offerees of any
Offered Securities is subject in all cases to the preparation, execution and
delivery by the Company and the Offerees of a purchase agreement relating to
such Offered Securities reasonably satisfactory in form and substance to the
Offerees and their respective counsel.

               (d) Further Sale. In each case, any Offered Securities not
purchased by the Offerees or other Person or Persons in accordance with Section
13(c) may not be sold or otherwise disposed of until they are again offered to
the Offerees under the procedures specified in Sections 13(a), 13(b) and 13(c).

               (e) Waiver of Right of First Refusal. The rights of the Investors
pursuant to this Section 13 may be waived as to all of such Investors by the
affirmative vote or written consent of holders of at least a majority in
interest of the then outstanding Restricted Stock, and any such waiver shall be
binding on all Investors, even if any of such Investors do not execute such
waiver and irrespective of whether one or more Investors participates in the
purchase of the Offered Securities.

                             SHAREHOLDERS AGREEMENT
                             ----------------------

         SHAREHOLDERS AGREEMENT made this 5th day of September, 2001 by and
among (i) FASTNET CORPORATION, a Pennsylvania corporation (the "Company"), (ii)
holders of Common Stock or options to acquire Common Stock whose names are set
forth under the heading "Holders" on Schedule I hereto and each person who
shall, after the date hereof, join in and become a party to this Agreement by
executing and delivering to the Company an Instrument of Accession in the form
of Schedule II hereto (the persons described in this clause (ii) such persons
being referred to collectively as the "Holders" and singularly as a "Holder")
and (iii) those persons whose names are set forth under the heading "Investors"
on Schedule I hereto (the persons described in this clause (iii) being referred
to collectively as the "Investors").

                                   WITNESSETH:

         WHEREAS, the Holders currently own collectively 8,860,333 shares of the
Common Stock, no par value (the "Common Stock"), of the Company; and

         WHEREAS, the Investors are acquiring an aggregate of up to 5,494,505
shares of the Company's Series A Convertible Preferred Stock, no par value (the
"Preferred Stock"), of the Company pursuant to a certain Series A Convertible
Preferred Stock Purchase Agreement dated as of the date hereof, by and among the
Investors and the Company (the "Purchase Agreement"). Capitalized terms used by
not defined herein shall have the meaning set forth in the Purchase Agreement.

         NOW, THEREFORE, in consideration of the mutual covenants herein
contained and other good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, intending to be legally bound hereby, the
Company, the Holders and the Investors agree as follows:

         1. Prohibited Transfers. The Holders shall not sell, assign, transfer,
pledge, hypothecate, mortgage or dispose of, by gift or otherwise, or in any way
encumber, all or any part of the Shares (as hereinafter defined) owned by them
except in compliance with the terms of this Agreement. For purposes of this
Agreement, the term "Shares" shall mean and include all shares of Common Stock
and Preferred Stock of the Company owned by the Holders, whether presently held
or hereafter acquired. The Company shall not transfer on its books any shares of
its capital stock which are subject to this Agreement unless the provisions
hereof have been complied with in full. Any purported transfer by a Holder of
capital stock of the Company without full compliance with the provisions of this
Agreement shall be null and void.

         2. Right of First Refusal on Dispositions by the Holders. If at any
time any of the Holders wishes to sell, assign, transfer or otherwise dispose of
any or all Shares owned by him pursuant to the terms of a bona fide offer
received from a third party, he shall submit a written offer to sell such Shares
to the Company and the Investors on terms and conditions, including price, not
less favorable to the Company than those on which he proposes to sell such
Shares to such third party (the "Offer"). The Offer shall disclose the identity
of the proposed purchaser or


                         Shareholders Agreement - Page 2

transferee, the Shares proposed to be sold or transferred, the agreed terms of
the sale or transfer, including price, and any other material facts relating to
the sale or transfer. Within fifteen (15) days after receipt of the Offer, the
Company shall give notice to the Holder of its intent to purchase all or any
portion of the offered Shares on the same terms and conditions as set forth in
the Offer. If, for any reason whatever, the Company shall not exercise its right
to purchase all of the offered Shares as provided herein, then each of the
Investors shall have the right to purchase, on the same terms and conditions set
forth in the Offer, that portion of the offered Shares which the Company shall
not have agreed to purchase from the Holder (all such remaining shares being
referred to as the "Remaining Offered Shares") to be determined in the manner
set forth herein. Each Investor shall have the right to purchase that number of
the Remaining Offered Shares as shall be equal to the aggregate Remaining
Offered Shares multiplied by a fraction, the numerator of which is the number of
shares of Stock (as defined below) of the Company then owned by such Investor
and the denominator of which is the aggregate number of shares of said Stock
then issued and outstanding and held by all the Investors. The amount of Shares
each Investor or Qualified Transferee, as that term is defined below, is
entitled to purchase under this Section 2 shall be referred to as such
Investor's "Pro Rata Fraction." Each Investor shall have the right to transfer
his right to any Pro Rata Fraction or part thereof to any Qualified Transferee.
In the event an Investor does not wish to purchase or to transfer his right to
purchase his Pro Rata Fraction, then any Investors who so elect shall have the
right to purchase, on a PRO RATA basis with any other Investors who so elect,
any Pro Rata Fraction not purchased by an Investor or Qualified Transferee. Each
Investor shall act upon the Offer as soon as practicable after receipt from the
Company of notice that it has not elected to purchase all of the offered Shares,
and in all events within fifteen (15) days after receipt thereof. Each Investor
shall have the right to accept the Offer as to all or part of the Remaining
Offered Shares offered thereby. In the event that an Investor shall elect to
purchase all or part of the Remaining Offered Shares covered by the Offer, said
Investor shall individually communicate in writing such election to purchase to
whichever of the Holders has made the Offer, which communication shall be
delivered by hand or mailed to such Holder at the address set forth in Section 7
below and shall, when taken in conjunction with the Offer be deemed to
constitute a valid, legally binding and enforceable agreement for the sale and
purchase of the Shares covered thereby.

         In the event that the Company and the Investors, taken together, do not
purchase all of the Shares offered by a Holder pursuant to the Offer within 45
days after the Offer is delivered to the Company, such unsold Shares may be sold
by such Holder at any time within the 90-day period thereafter, but subject to
the provisions of Section 3 below. Any such sale shall be at not less than the
price and upon other terms and conditions, if any, not more favorable to the
purchaser than those specified in the Offer. Any Shares not sold within such
90-day period shall continue to be subject to the requirements of a prior offer
and re-sale pursuant to this Section.

         For the purposes of this Agreement, "Stock" shall mean and include all
shares of Common Stock, and all other securities of the Company (including the
Preferred Stock) which may be exchangeable for, convertible into or issued in
exchange for or in respect of shares of Common Stock (whether by way of stock
split, stock dividends, combination, reclassification, reorganization or any
other means); references to "shares of Stock" shall mean shares of Stock on an
as-converted and as-exchanged for Common Stock basis. For purposes of this
Section 2, a "Qualified Transferee" of an Investor shall mean any person (i) who
is an Investor, (ii) who is an


                         Shareholders Agreement - Page 3

"affiliated person" of an Investor, as that term is defined in the Investment
Company Act of 1940 or (iii) who is a partner of an Investor.

         3. Right of Participation in Sales by Holders. If at any time any
Holder wishes to sell, or otherwise dispose of any Shares owned by him to any
person (the "Purchaser") in a transaction which is subject to the provisions of
Section 2 hereof and subject to the exercise of rights under such Section 2,
each Investor shall have the right to require, as a condition to such sale or
disposition, that the Purchaser purchase from each of the Holder and such
Investors at the same price per Share and on the same terms and conditions as
involved in such sale or disposition by the Holder a number of shares of Stock
based upon a fraction, the numerator of which is the number of shares of Stock
of the Company then owned by the Holder or such participating Investor, as
applicable, and the denominator of which is the aggregate number of shares of
Stock held by the Holder and all participating Investors. Each Investor wishing
so to participate in any such sale or disposition shall notify the selling
Holder of such intention as soon as practicable after receipt of the Offer made
pursuant to Section 2, and in all events within fifteen (15) days after receipt
thereof. In the event that an Investor shall elect to participate in such sale
or disposition, said Investor shall individually communicate such election to
the selling Holder, which communication shall be delivered by hand or mailed to
such Holder at the address set forth in Section 7 below. The Holder and/or each
participating Investor shall sell to the Purchaser all, or at the option of the
Purchaser, any part of the Stock proposed to be sold by them at not less than
the price and upon other terms and conditions, if any, not more favorable to the
Purchaser than those originally offered; PROVIDED, HOWEVER, that any purchase of
less than all of such Stock by the Purchaser shall be made from the Holder
and/or each participating Investor based upon a fraction, the numerator of which
is the number of shares of Stock of the Company then owned by the Holder or such
participating Investor and the denominator of which is the aggregate number of
shares of Stock held by the Holder and all of the participating Investors. The
selling Holder or Investor shall use his or its best efforts to obtain the
agreement of the Purchaser to the participation of the participating Investors
in the contemplated sale, and shall not sell any Stock to such Purchaser if such
Purchaser declines to permit the participating Investors to participate pursuant
to the terms of this Section 3. The provisions of this Section 3 shall not apply
to the sale of any Shares by a Holder to an Investor pursuant to an Offer under
Section 2.

         4. Permitted Transfers.

         (i) Anything herein to the contrary notwithstanding, the provisions of
Sections 1, 2, 3 and 8 shall not apply to: (a) any transfer of Shares by a
Holder or Investor by gift or bequest or through inheritance to, or for the
benefit of, any member or members of his or her immediate family (which shall
include any spouse, lineal ancestor or descendant or sibling) or to a trust,
partnership or limited liability company for the benefit of such members; (b)
any transfer of Shares by a Holder or Investor to a trust in respect of which he
or she serves as trustee, provided that the trust instrument governing said
trust shall provide that such transferee, as trustee, shall retain sole and
exclusive control over the voting and disposition of said Shares until the
termination of this Agreement; (c) any sale of Common Stock in a public offering
pursuant either to a registration statement filed by the Company with the
Securities and Exchange Commission, in accordance with Rule 144 (including for
this purpose paragraph (f) of Rule 144) or in a broker


                         Shareholders Agreement - Page 4

transaction sale into the public markets made in reliance on the exemption
provided by Section 4(1) of the Securities Act such that all transfer
restrictions, and restrictive legends with respect thereto, are removed upon
consummation of the sale; (d) any repurchase of shares of Common Stock from
officers, employees, directors or consultants of the Company which are subject
to restrictive stock purchase agreements under which the Company has the option
to repurchase such shares upon the occurrence of certain events, including
termination of employment; and (e) any transfer to a Qualified Transferee.

         (ii) In the event of any such transfer, other than pursuant to
subsection (i)(c) of this Section 4, the transferee of the Shares shall hold the
Shares so acquired with all the rights conferred by, and subject to all the
restrictions imposed by this Agreement, and as a condition to such transfer,
each such transferee shall execute and deliver an instrument of accession in the
form of Schedule II agreeing to be bound as a Holder or Investor, as applicable,
by the provisions of this Agreement.

         5. Board of Directors.

         Each of the parties covenants and agrees to vote, to the extent
possible, all shares of Stock of the Company now owned or hereafter acquired by
such party so that the Company's Board of Directors shall consist of no more
than seven (7) members. Any vacancy on the Board of Directors created by the
resignation, removal, incapacity or death of any person designated by the
holders of Preferred Stock in accordance with the Articles shall be filled by
another person designated by the holders of a majority of the Preferred Stock
and any vacancy on the Board of Directors created by the resignation, removal,
incapacity or death of any person designated by the holders of Common Stock in
accordance with the Articles shall be filled by another person designated by the
holders of a majority of the Common Stock. Subject to applicable regulations and
Nasdaq requirements, and for as long as this Agreement is in effect, each of the
parties further covenants and agrees to cause at least one of the directors
elected by the Preferred Stock to be a member of the Compensation Committee of
the Board of Directors, and the other director elected by the Preferred Stock to
be a member of the Audit Committee of the Board of Directors.

         6. Termination. This Agreement, and the respective rights and
obligations of the parties hereto, shall terminate at such time that less than
25% of the shares of Preferred Stock issued under the Purchase Agreement remain
outstanding.

         7. Notices. All notices and other communications hereunder shall be in
writing and shall be deemed to have been given when delivered or mailed by first
class, registered or certified mail (air mail if to or from outside the United
States), return receipt requested, postage prepaid, if to each Holder at his
respective address set forth on Schedule I hereto or on the Instrument of
Accession pursuant to which he became a party to this Agreement, and if to the
Investors, at their respective addresses set forth on Schedule I hereto or to
such other address as the addressee shall have furnished to the other parties
hereto in the manner prescribed by this Section 9.

         8. Lock-up Agreement. Each Holder and Investor hereby agrees not to
sell any Shares now owned or hereafter acquired by it without the prior written
consent of the Board of Directors of the Company (including the directors
elected by the holders of Preferred Stock) until


                         Shareholders Agreement - Page 5

the first to occur of (i) March 3, 2002 or (ii) the consolidation or merger of
the Company into or with any other entity or entities if the shareholders of the
Company immediately prior to such merger own, upon consummation of such merger,
securities representing less than a majority of the voting power of the Company.

         9. Specific Performance. The rights of the parties under this Agreement
are unique and, accordingly, the parties shall, in addition to such other
remedies as may be available to any of them at law or in equity, have the right
to enforce their rights hereunder by actions for specific performance to the
extent permitted by law.

         10. Legend. The certificates representing the Shares shall bear a
legend indicating the existence of the restrictions imposed hereby.

         11. Entire Agreement. This Agreement and the Purchase Agreement
(including any and all exhibits, schedules and other instruments contemplated
thereby) constitute the entire agreement among the parties with respect to the
subject matter hereof and supersede all prior agreements and understandings
between them or any of them as to such subject matter.

         12. Waivers and Further Agreements. Any of the provisions of this
Agreement may be waived by an instrument in writing executed and delivered by
Investors holding at least a majority in interest of the Common Stock (including
for this purpose shares of Common Stock issuable upon conversion of Preferred
Stock) then held or deemed to be held by all Investors. Any waiver by any party
of a breach of any provision of this Agreement shall not operate or be construed
as a waiver of any subsequent breach of that provision or of any other provision
hereof. Each of the parties hereto agrees to execute all such further
instruments and documents and to take all such further action as any other party
may reasonably require in order to effectuate the terms and purposes of this
Agreement. Notwithstanding the foregoing, no waiver approved in accordance
herewith shall be effective if and to the extent that such waiver grants to any
one or more Investors any rights more favorable than any rights granted to all
other Investors or otherwise treats any one or more Investors differently than
all other Investors.

         13. Amendments. Except as otherwise expressly provided herein, this
Agreement may not be amended except by an instrument in writing executed by (i)
the Company, (ii) Investors holding at least a majority in interest of the
shares of Common Stock held by the Investors (including for this purpose shares
of Common Stock issuable upon conversion of Preferred Stock) and (iii) Holders
holding a majority of the Shares held by all Holders under this Agreement.

         14. Assignment; Successors and Assigns. This Agreement shall be binding
upon and shall inure to the benefit of the parties hereto and their respective
heirs, executors, legal representatives, successors and permitted transferees,
except as may be expressly provided otherwise herein.

         15. Severability. In case any one or more of the provisions contained
in this Agreement shall for any reason be held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect any other provision of this


                         Shareholders Agreement - Page 6

Agreement and such invalid, illegal and unenforceable provision shall be
reformed and construed so that it will be valid, legal, and enforceable to the
maximum extent permitted by law.

         16. Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         17. Section Headings. The headings contained in this Agreement are for
reference purposes only and shall not in any way affect the meaning or
interpretation of this Agreement.

         18. Governing Law. This Agreement shall be construed and enforced in
accordance with and governed by the internal laws of the Commonwealth of
Pennsylvania, without regard to its principles of conflicts of laws.

         19. Additional Parties. Any purchaser of Preferred Stock pursuant to
the Purchase Agreement shall become a party to this Agreement by executing and
delivering to the Company a counterpart to this Agreement. Upon such execution
and delivery, such purchaser shall be deemed to be an "Investor" hereunder with
all of the rights and obligations thereof.

         20. Shareholder Approval. Each Large Holder (as defined below) agrees
with the Investors that it shall, in person or by proxy at the shareholder
meeting of the Company convened pursuant to Section 5.13 of the Purchase
Agreement, vote all of its Shares in favor of the issuance of the securities to
be sold by the Company to the Investors (including any Additional Purchasers) at
the Subsequent Closing in light of the overall transaction contemplated by the
Purchase Agreement. "Large Holder" shall mean the four Holders identified as
such on Schedule I hereto.
