civil action in a court of appropriate jurisdiction to solve disputes hereunder.
Nothing contained in this Section 7.5 shall prevent the parties from settling

of any Shares issued to or held by Seller, including without limitation a
voluntary or involuntary sale, assignment, transfer, pledge, hypothecation,
encumbrance, disposal, loan, gift, attachment or levy (a "Transfer"), except as
--------
provided in this Article VIII, and any such Transfer of Shares or attempted
Transfer of Shares in contravention of this Agreement shall be void and
ineffective for any purpose and shall not confer on any transferee or purported
transferee any rights whatsoever.

(b) Right of First Refusal.
----------------------

(i) If, prior to an initial public offering of Buyer's securities
or a merger or sale of Buyer, Seller proposes to Transfer (or is required by
operation of law or other involuntary transfer) any or all of the Shares
standing in Seller's, Seller shall first offer such Shares to the Company in
accordance with the following provisions:

(A) Seller shall deliver a written notice (a "Notice") to
------
Buyer stating (1) Seller's bona fide intention to Transfer such Shares, (2)
the name and address of the proposed transferee, (3) the number of Shares
to be transferred, and (4) the purchase price per Share and terms of
payment for which Seller proposes to Transfer such Shares.

(B) Within 60 days after receipt of the Notice, Buyer or its
designee shall have the first right to purchase or obtain such Shares, upon
the price and terms of payment designated in the Notice. If the Notice
provides for the payment of non-cash consideration, Buyer at its option may
pay the consideration in cash equal to Buyer's good faith estimate of the
present fair market value of the non-cash consideration offered.

(C) If Buyer or its designee elects not to purchase or obtain
all of the Shares designated in the Notice, then Seller may Transfer the
Shares referred to in the Notice to the proposed transferee, providing such
Transfer (1) is completed within 30 days after the expiration of Buyer's
right to purchase or obtain such Shares, (2) is made at the price and terms
designated in the Notice, and (3) the proposed transferee agrees to be
bound by the terms and provisions of this Article VIII and to become a
party to an agreement containing such provisions immediately upon receipt
of such Shares. If such Shares are not so transferred, Seller must give
notice in accordance with this paragraph prior to any other or subsequent
Transfer of such Shares.

(ii) Notwithstanding Section 8.1(a), Seller may Transfer Shares:
(A) to either or both of Seller's shareholders as of the date hereof (a
"Shareholder"), (B) to a Shareholder's spouse, child, grandchild,
-----------
parent, brother, or sister ("Immediate Family"), or to a trust established for
------------------
the benefit of a member or members of a Shareholder's Immediate Family, (C) to
an Affiliate or (D) to the estate of any of the foregoing by gift, will or
intestate succession; provided that Seller notifies Buyer of such Transfer not
less than 10 nor more than 90 days prior to the Transfer and that the proposed
transferee agrees to be bound by the terms and provisions

of this Agreement and to become a party to this Agreement immediately upon the
receipt of such Shares.

(c) No Transfer to Competitors. Seller may not Transfer any Shares
to a competitor of Buyer, or to any stockholder, partner or other beneficial
holder of an equity ownership interest in a competitor, other than pursuant to a
merger, combination, or other transaction approved by the Board of Directors of
Buyer.

(d) Legends on Stock Certificates. Each certificate representing
-----------------------------
shares issued pursuant to this Agreement shall be endorsed with the following
legends:

THE SHARES EVIDENCED BY THIS CERTIFICATE ARE SUBJECT TO AN
AGREEMENT BETWEEN XOOM, INC. (THE "COMPANY"0 AND THE HOLDER, PROVIDING FOR,
AMONG OTHER MATTERS, THE COMPANY'S RIGHT OF FIRST REFUSAL TO PURCHASE THE
SECURITIES REPRESENTED BY THIS CERTIFICATE. A COPY OF USCH AGREEMENT IS ON
FILE AT THE PRINCIPAL BUSINESS OFFICE OF THE COMPANY.

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND
MAY NOT BE SOLD, TRANSFERRED, ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN
EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT COVERING SUCH SECURITIES,
THE SALE IS MADE IN ACCORDANCE WITH RULE 144 OR ITS SUCCESSOR RULE UNDER
THE ACT, OR THE COMPANY RECEIVES AN OPINION OF COUNSEL SATISFACTORY TO THE
COMPANY THAT EXEMPTIONS FROM SUCH REGISTRATION AND FROM THE PROVISIONS OF
ANY APPLICABLE STATE "BLUE SKY" LAWS ARE AVAILABLE.

Under no circumstances shall any Transfer of any Shares subject hereto be
valid until the proposed transferee thereof shall have executed and become a
party to the agreement described in Section 8.1(b)(i)(C) and thereby shall have
become subject to all of the provisions of this Article VIII; and
notwithstanding any other provisions of this Agreement, no such Transfer of any
kind shall in any event result in the non-applicability of the provisions hereof
at any time to any of the Shares subject hereto. Seller understands and
acknowledges that Buyer need not register a transfer of Shares, and may instruct
its transfer agent not to register a transfer of Shares, unless the conditions
specified in the foregoing legend are satisfied.

(e) Acknowledgments. Seller acknowledges that other stockholders
---------------
of the Company may have restrictions on their stockholdings different than the
terms contained herein.

8.2 LOCK-UP AGREEMENT. Seller, if requested by an underwriter of Shares or
other securities of Buyer, shall not sell or otherwise transfer or dispose of
any Shares held by Seller during the 180-day period following the effective date
of a registration statement of Buyer filed under the Act or such shorter period
of time as the underwriter shall require, provided that all officers and
directors of Buyer who hold common stock (or other securities) of Buyer enter
into similar agreements. If requested by the underwriter, Seller will reaffirm
the agreement set forth in this Section 8.2 in a separate writing in a form
satisfactory to such underwriter. Buyer may impose stop-transfer instructions

in addition to any other relief to which that party may be entitled.

This Note shall be interpreted and enforced in all respects in accordance
with the internal laws of the State of California.

due to: (1) any act of fraud, dishonesty, or gross negligence (including any
failure to act) made, engaged in, or conducted by Consultant in the course of
providing the services contemplated under this Agreement; (2) willful and wanton
misrepresentation to the Company which is materially injurious to the Company;
or (3) willful failure without reasonable justification to comply with a
material, reasonable and lawful instruction by the Company.

(b) At Will. At any time, either the Company or Consultant may terminate,
-------
without liability, the Consulting Period for any reason, with or without cause,
by giving thirty (30) days' advance written notice to the other party. If
Consultant terminates the consulting relationship with the Company pursuant to
this Section 4(b), the Company shall have the option, in its complete
discretion, to terminate Consultant immediately without the running of the
notice period, and such termination shall be deemed termination for cause. The
Company shall pay

Consultant the compensation to which it is entitled pursuant to Section 3(a) for
services rendered through the date of termination, and thereafter all
obligations of the Company hereunder shall terminate. Consultant hereby agrees
that the Company may dismiss it under this Section 4(b) without regard (i) to
any general or specific policies (whether written or oral) of the Company
relating to the employment, retention or termination of its employees or
consultants, or (ii) to any statements made to Consultant, whether made orally
or contained in any document, pertaining to Consultant's relationship with the
Company; provided, however, that if the Company terminates Consultant without
cause prior to the end of the Consulting Period, the Company shall continue
paying Consultant its monthly compensation through the end of the Consulting
Period.

5. Termination Obligations.
-----------------------

(a) Consultant hereby acknowledges and agrees that all personal property,
including, without limitation, all books, manuals, records, reports, notes,
contracts, lists, blueprints, and other documents, or materials, or copies
thereof, Proprietary Information (as defined below), and equipment furnished to
or prepared by Consultant in the course of or incident to rendering of services
to the Company (but without affecting Consultant's rights as Secured Party under
that Security Agreement between Consultant and the Company of even date
herewith), including, without limitation, records and any other materials
pertaining to Invention Ideas (as defined below), belong to the Company and
shall be promptly returned to the Company upon termination of the Consulting
Period. Following termination, the Consultant will not retain any written or
other tangible material containing any Proprietary Information.

(b) The representations and warranties contained herein and Consultant's
obligations under Sections 4, 5, 6, and 7 shall survive termination of the
Consulting Period and the expiration of this Agreement.

(c) Consultant undertakes to ensure that its employees comply with all of
the requirements and obligations described in Sections 5 through 9 hereof,
inclusive, and shall be liable for any breach by any of its employees of such
sections.

6. Proprietary Information.
-----------------------

(a) Defined. "Proprietary Information" is all information and any idea in
-------
whatever form, tangible or intangible, pertaining in any manner to the business
of the Company or any Affiliated Company, or to its clients, consultants, or
business associates, unless: (i) the information is or becomes publicly known
through lawful means; (ii) the information was rightfully in Consultant's
possession or part of Consultant's general knowledge prior to the Consulting
Period; or (iii) the information is disclosed to Consultant without confidential
or proprietary restrictions by a third party who rightfully possesses the
information (without confidential or proprietary restriction) and did not learn
of it, directly or indirectly, from the Company.

(b) General Restrictions on Use. Consultant agrees to hold all
---------------------------
Proprietary Information in strict confidence and trust for the sole benefit of
the Company and not to, directly

or indirectly, disclose, use, copy, publish, summarize, or remove from the
Company's premises any Proprietary Information (or remove from the premises any
other property of the Company), except (i) during the Consulting Period to the
extent necessary to carry out Consultant's responsibilities under this
Agreement, and (ii) after termination of the Consulting Period as specifically
authorized in writing by the Company's Board of Directors.

(c) Interference with Business; Competitive Activities. Consultant
--------------------------------------------------
acknowledges that the pursuit of the activities forbidden by this Section 6(c)
would necessarily involve the use or disclosure of Proprietary Information in
breach of Section 6(b), but that proof of such breach would be extremely
difficult. To forestall such disclosure, use, and breach, and in consideration
of retaining Consultant under this Agreement, Consultant agrees that during the
Consulting Period and for a period of one (1) year after termination of the
Consulting Period, Consultant shall not, for itself or any third party, directly
or indirectly (i) divert or attempt to divert from the Company (or any
Affiliated Company) any business of any kind in which it is engaged, including,
without limitation, the solicitation of or interference with any of its
suppliers or customers; or (ii) employ, solicit for employment, or recommend for
employment any person employed by the Company, or by any Affiliated Company.

(d) Remedies. Nothing in this Section 6 is intended to limit any remedy
--------
of the Company under the California Uniform Trade Secrets Act (California Civil
Code Section 3426), or otherwise available under law.

7. Consultant's Inventions and Ideas.
---------------------------------

(a) Defined. The term "Invention Ideas" means any and all ideas,
-------
processes, trademarks, service marks, inventions, technology, computer programs,
original works of authorship, designs, formulas, discoveries, patents,
copyrights, and all improvements, rights, and claims related to the foregoing
that are conceived, developed, or reduced to practice by the Consultant alone or
with others in the course of providing consulting services to the Company.

(b) Disclosure. Consultant agrees to maintain adequate and current
----------
written records on the development of all Invention Ideas and to disclose
promptly to the Company all Invention Ideas and relevant records, which records
will remain the sole property of the Company. Consultant further agrees that all
information and records pertaining to any idea, process, trademark, service
▇▇▇▇, invention, technology, computer program, original work of authorship,
design, formula, discovery, patent, or copyright that Consultant does not
believe to be an Invention Idea, but is conceived, developed, or reduced to
practice by Consultant (alone or with others) during his Consulting Period or
during the one year period following termination of the Consulting Period, shall
be promptly disclosed to the Company (such disclosure to be received in
confidence). The Company shall examine such information to determine if in fact
the idea, process, or invention, etc., is an Invention Idea subject to this
Agreement.

(c) Assignment. Consultant agrees to assign to the Company, without
----------
further consideration, his entire right, title, and interest (throughout the
United States and in all foreign countries), free and clear of all liens and
encumbrances, in and to each Invention Idea, which

shall be the sole property of the Company, whether or not patentable. In the
event any Invention Idea shall be deemed by the Company to be patentable or
otherwise registrable, Consultant shall assist the Company (at Company's
expense) in obtaining letters patent or other applicable registrations thereon
and shall execute all documents and do all other things (including testifying at
the Company's expense) necessary or proper to obtain letters patent or other
applicable registrations thereon and to vest the Company, or any Affiliated
Company specified by the Company, with full title thereto. Should the Company be
unable to secure Consultant's signature on any document necessary to apply for,
prosecute, obtain, or enforce any patent, copyright, or other right or
protection relating to any Invention Idea, whether due to Consultant's mental or
physical incapacity or any other cause, Consultant hereby irrevocably designates
and appoints Company and each of its duly authorized officers and agents as
Consultant's agent and attorney in fact, to act for and in Consultant's behalf
and stead and to execute and file any such document, and to do all other
lawfully permitted acts to further the prosecution, issuance, and enforcement of
patents, copyrights, or other rights or protections with the same force and
effect as if executed and delivered by Consultant.

(d) Exclusions. Except for the relational database management system
----------
developed by Consultant known as rdb, Consultant acknowledges that there are no
ideas, processes, trademarks, service marks, technology, computer programs,
original works of authorship, designs, formulas, inventions, discoveries,
patents, copyrights, or improvements to the foregoing that it desires to exclude
from the operation of this Agreement. To the best of Consultant's knowledge,
there is no existing contract in conflict with this Agreement or any other
contract to assign ideas, processes, trademarks, service marks, inventions,
technology, computer programs, original works of authorship, designs, formulas,
discoveries, patents, or copyrights that is now in existence between Consultant
and any other person or entity.

(e) Post-Termination Period. Because of the difficulty of establishing
-----------------------
when any idea, process, invention, etc., is first conceived or developed by
Consultant, or whether it results from access to Proprietary Information or the
Company's equipment, facilities, and data, Consultant agrees that any idea,
process, trademark, service ▇▇▇▇, technology, computer program, original work of
authorship, design, formula, invention, discovery, patent, copyright, or any
improvement, rights, or claims having a direct bearing or relevance to the
Company's assets or operations shall be presumed to be an Invention Idea if it
is conceived, developed, used, sold, exploited, or reduced to practice by
Consultant or with the aid of Consultant within six (6) months year after
termination of the Consulting Period. Consultant can rebut the above presumption
if it proves that the invention, idea, process, etc., (i) was first conceived or
developed after termination of the Consulting Period, (ii) was conceived or
developed entirely on Consultant's own time without using the Company's
equipment, supplies, facilities, or Proprietary Information, and (iii) did not
result from any work performed by Consultant for the Company.

8. Independent Contractor Relationship.
-----------------------------------

(a) Nature of Relationship. In performing services to the Company
----------------------
pursuant to this Agreement, Consultant's relationship with the Company will be
that of an independent

contractor and nothing in this Agreement should be construed to create a
partnership, joint venture, or employer-employee relationship. Consultant
acknowledges and agrees that neither Consultant nor any person associated with
Consultant shall be entitled to receive or otherwise participate in any employee
benefits of any nature which the Company provides or makes available to any of
its employees.

(b) Taxes and Records. Consultant agrees that it will be solely
-----------------
responsible for, and will file and pay on a timely basis, all withholding
required by federal, state or local law with respect to Consultant's performance
of the services.

9. No Conflict of Interest.
-----------------------

Consultant agrees during the term of this Agreement not to accept work or
enter into a contract or accept an obligation, inconsistent or incompatible with
Consultant's obligations under this Agreement or the scope of services rendered
for Company. Consultant warrants that to the best of Consultant's knowledge,
there is no other contract or duty now in existence inconsistent with this
Agreement. Consultant further agrees not to disclose to the Company, or bring
onto the Company's premises, or induce the Company to use any confidential
information that belongs to anyone other than the Company or Consultant.
Consultant agrees to indemnify the Company from any and all loss or liability
incurred by reason of the alleged breach by Consultant of any confidentiality or
services agreement with anyone other than the Company.

10. Assignment; Successors and Assigns.
----------------------------------

Consultant shall not assign, sell, transfer, delegate or otherwise
dispose of, whether voluntarily or involuntarily, or by operation of law, any
rights or obligations under this Agreement, nor shall Consultant's rights be
subject to encumbrance or the claims of creditors. Any purported assignment,
transfer, or delegation shall be null and void. Nothing in this Agreement shall
prevent the consolidation of the Company with, or its merger into, any other
corporation, or the sale by the Company of all or substantially all of its
properties or assets, or the assignment by the Company of this Agreement and the
performance of its obligations hereunder to any successor in interest or any
Affiliated Company. Subject to the foregoing, this Agreement shall be binding
upon and shall inure to the benefit of the parties and their respective heirs,
legal representatives, successors, and permitted assigns, and shall not benefit
any person or entity other than those enumerated above.

11. Notices.
-------

All notices or other communications required or permitted hereunder shall
be made in writing and shall be deemed to have been duly given if delivered by
hand or mailed, postage prepaid, by certified or registered mail, return receipt
requested, and addressed to the Company at:

Notice of change of address shall be effective only when done in accordance with
this section.

12. Entire Agreement.
----------------

The terms of this Agreement are intended by the parties to be the full
and final expression of their agreement with respect to the retention of
Consultant by the Company and may not be contradicted by evidence of any prior
or contemporaneous agreement. The parties further intend that this Agreement
shall constitute the complete and exclusive statement of its terms and that no
extrinsic evidence whatsoever may be introduced in any judicial, administrative,
or other legal proceeding involving this Agreement. This Agreement fully
supersedes any prior oral or written consulting or other agreements between the
Consultant and the Company.

13. Amendments.
----------
This Agreement may not be modified or amended, except by an instrument in
writing, signed by the Consultant and by a duly authorized representative of the
Company.

14. Severability; Enforcement.
-------------------------

If any provision of this Agreement shall be held to be invalid,
unenforceable, or void, the remainder of this Agreement shall remain in full
force and effect. It is the intention of the parties that the covenants
contained in Section 6 and 7 shall be enforced to the greatest extent (but to no
greater extent) in time, area, and degree of participation as is permitted by
the law of that jurisdiction whose law is found to be applicable to any acts
allegedly in breach of these covenants.

15. Governing Law.
-------------

This Agreement shall be governed by and construed in accordance with the
laws of the State of California, without regard to conflicts of law principles.

16. Consultant Acknowledgment.
-------------------------

Consultant acknowledges (i) that he has consulted with or has had the
opportunity to consult with independent counsel of his own choice concerning
this Agreement and has been advised to do so by the Company, and (ii) that it
has read and understands the Agreement, is fully aware of its legal effect, and
has entered into it freely based on his own judgment and not in reliance upon
any representation or promises made by the Company other than those contained in
writing herein.

17. Remedies.
--------

(a) Injunctive Relief. The parties agree that in the event of any breach
-----------------
or threatened breach of any of the covenants in Sections 6 or 7, the damage or
imminent damage to the value and the goodwill of the Company's business will be
irreparable and extremely difficult to estimate, making any remedy at law or in
damages inadequate. Accordingly, the parties agree that the Company shall be
entitled to injunctive relief without bond against Consultant in the event of
any breach or threatened breach of any such provisions by Consultant, in
addition to any other relief (including damages) available to the Company under
this Agreement or under law.

(b) Enforcement. In the event of any legal action required to enforce or
-----------
defend this Agreement, the prevailing party shall be entitled to an award of
attorneys' fees and legal costs, in addition to other relief.

The parties have duly executed this Agreement as of the date first
written above.
