                        iBEAM BROADCASTING CORPORATION

                           INDEMNIFICATION AGREEMENT

     This Indemnification Agreement ("Agreement") is made as of this ___ day of
_________, 2000, by and between iBEAM Broadcasting Corporation, a Delaware
corporation (the "Company"), and ______________________ ("Indemnitee").

     WHEREAS, the Company and Indemnitee recognize the increasing difficulty in
obtaining directors' and officers' liability insurance, the significant
increases in the cost of such insurance and the general reductions in the
coverage of such insurance;

     WHEREAS, the Company and Indemnitee further recognize the substantial
increase in corporate litigation in general, subjecting officers and directors
to expensive litigation risks at the same time as the availability and coverage
of liability insurance has been severely limited; and

     WHEREAS, the Company desires to attract and retain the services of highly
qualified individuals, such as Indemnitee, to serve as officers and directors of
the Company and to indemnify its officers and directors so as to provide them
with the maximum protection permitted by law.

     NOW, THEREFORE, in consideration for Indemnitee's services as an officer or
director of the Company, the Company and Indemnitee hereby agree as follows:

     1.   Indemnification.

          (a)  Third Party Proceedings. The Company shall indemnify Indemnitee
if Indemnitee is or was a party or is threatened to be made a party to any
threatened, pending or completed action, suit, proceeding or any alternative
dispute resolution mechanism, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the Company) by reason
of the fact that Indemnitee is or was a director, officer, employee or agent of
the Company, or any subsidiary of the Company, or by reason of the fact that
Indemnitee is or was serving at the request of the Company as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, against expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement (if such settlement is approved
in advance by the Company, which approval shall not be unreasonably withheld)
actually and reasonably incurred by Indemnitee in connection with such action,
suit or proceeding if Indemnitee acted in good faith and in a manner Indemnitee
reasonably believed to be in or not opposed to the best interests of the
Company, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe Indemnitee's conduct was unlawful. The termination
of any action, suit or proceeding by judgment, order, settlement, conviction, or
upon a plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that Indemnitee did not act in good faith and in a manner which
Indemnitee reasonably believed to be in or not opposed to the best interests of
the Company, and, with respect to any
<PAGE>

criminal action or proceeding, had reasonable cause to believe that Indemnitee's
conduct was unlawful.

          (b)  Proceedings By or in the Right of the Company.  The Company shall
indemnify Indemnitee if Indemnitee was or is a party or is threatened to be made
a party to any threatened, pending or completed action or suit by or in the
right of the Company or any subsidiary of the Company to procure a judgment in
its favor by reason of the fact that Indemnitee is or was a director, officer,
employee or agent of the Company, or any subsidiary of the Company, or by reason
of the fact that Indemnitee is or was serving at the request of the Company as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys' fees)
and, to the fullest extent permitted by law, amounts paid in settlement actually
and reasonably incurred by Indemnitee in connection with the defense or
settlement of such action or suit if Indemnitee acted in good faith and in a
manner Indemnitee reasonably believed to be in or not opposed to the best
interests of the Company, except that no indemnification shall be made in
respect of any claim, issue or matter as to which Indemnitee shall have been
adjudged to be liable to the Company unless and only to the extent that the
Court of Chancery of the State of Delaware or the court in which such action or
suit was brought shall determine upon application that, despite the adjudication
of liability but in view of all the circumstances of the case, Indemnitee is
fairly and reasonably entitled to indemnity for such expenses which the Court of
Chancery of the State of Delaware or such other court shall deem proper.

          (c)  Mandatory Payment of Expenses.  To the extent that Indemnitee has
been successful on the merits or otherwise in defense of any action, suit or
proceeding referred to in Subsections (a) and (b) of this Section 1, or in
defense of any claim, issue or matter therein, Indemnitee shall be indemnified
against expenses (including attorneys' fees) actually and reasonably incurred by
Indemnitee in connection therewith.

     2.   Agreement to Serve.  In consideration of the protection afforded
by this Agreement, if Indemnitee is a director of the Company he agrees to serve
as a director and not to resign voluntarily during such period without the
written consent of a majority of the Board of Directors until 90 days after the
effective date of this Agreement.  If Indemnitee is an officer of the Company
not serving under an employment contract, he agrees to serve in such capacity at
least for the same period of time and not to resign voluntarily during such
period without the written consent of a majority of the Board of Directors.
Following the applicable period set forth above, Indemnitee agrees to continue
to serve in such capacity at the will of the Company (or under separate
agreement, if such agreement exists) so long as he is duly appointed or elected
and qualified in accordance with the applicable provisions of the Bylaws of the
Company or any subsidiary of the Company or until such time as he tenders his
resignation in writing.  Nothing contained in this Agreement is intended to
create in Indemnitee any right to continued employment.

                                      -2-

     3.   Expenses; Indemnification Procedure.

          (a)  Advancement of Expenses.  The Company shall advance all expenses
incurred by Indemnitee in connection with the investigation, defense, settlement
or appeal of any civil or criminal action, suit or proceeding referenced in
Section 1(a) or (b) hereof (but not amounts actually paid in settlement of any
such action, suit or proceeding).  Indemnitee hereby undertakes to repay such
amounts advanced only if, and to the extent that, it shall ultimately be
determined that Indemnitee is not entitled to be indemnified by the Company as
authorized hereby.  The advances to be made hereunder shall be paid by the
Company to Indemnitee within thirty (30) days following delivery of a written
request therefor by Indemnitee to the Company.

          (b)  Notice/Cooperation by Indemnitee.  Indemnitee shall, as a
condition precedent to his right to be indemnified under this Agreement, give
the Company notice in writing as soon as practicable of any claim made against
Indemnitee for which indemnification will or could be sought under this
Agreement.  Notice to the Company shall be directed to the President of the
Company at the address shown on the signature page of this Agreement (or such
other address as the Company shall designate in writing to Indemnitee and given
as provided in Section 14).  In addition, Indemnitee shall give the Company such
information and cooperation as it may reasonably require and as shall be within
Indemnitee's power.

          (c)  Procedure.  Any indemnification and advances provided for in
Section 1 and this Section 3 shall be made no later than thirty (30) days after
receipt of the written request of Indemnitee.  If a claim under this Agreement,
under any statute, or under any provision of the Company's Certificate of
Incorporation or Bylaws providing for indemnification, is not paid in full by
the Company within thirty (30) days after a written request for payment thereof
has first been received by the Company, Indemnitee may, but need not, at any
time thereafter bring an action against the Company to recover the unpaid amount
of the claim and, subject to Section 13 of this Agreement, Indemnitee shall also
be entitled to be paid for the expenses (including attorneys' fees) of bringing
such action.  It shall be a defense to any such action (other than an action
brought to enforce a claim for expenses incurred in connection with any action,
suit or proceeding in advance of its final disposition) that Indemnitee has not
met the standards of conduct which make it permissible under applicable law for
the Company to indemnify Indemnitee for the amount claimed.  However, Indemnitee
shall be entitled to receive interim payments of expenses pursuant to Subsection
3(a) unless and until such defense may be finally adjudicated by court order or
judgment from which no further right of appeal exists.  It is the parties'
intention that if the Company contests Indemnitee's right to indemnification,
the question of Indemnitee's right to indemnification shall be for the court to
decide, and neither the failure of the Company (including its Board of
Directors, any committee or subgroup of the Board of Directors, independent
legal counsel, or its stockholders) to have made a determination that
indemnification of Indemnitee is proper in the circumstances because Indemnitee
has met the applicable standard of conduct required by applicable law, nor an
actual determination by the Company (including it Board of Directors, any
committee or subgroup of the Board of Directors, independent legal counsel, or
its stockholders) that Indemnitee has not met such applicable standard of
conduct, shall create a presumption that Indemnitee has or has not met the
applicable standard of conduct.

                                      -3-

          (d)  Notice to Insurers. If, at the time of the receipt of a notice of
a claim pursuant to Section 3(b) hereof, the Company has director and officer
liability insurance in effect, the Company shall give prompt notice of the
commencement of such proceeding to the insurers in accordance with the
procedures set forth in the respective policies. The Company shall thereafter
take all necessary or desirable action to cause such insurers to pay, on behalf
of the Indemnitee, all amounts payable as a result of such proceeding in
accordance with the terms of such policies.

          (e)  Selection of Counsel. In the event the Company shall be obligated
under Section 3(a) hereof to pay the expenses of any proceeding against
Indemnitee, the Company, if appropriate, shall be entitled to assume the defense
of such proceeding, with counsel approved by Indemnitee, upon the delivery to
Indemnitee of written notice of its election to do so. After delivery of such
notice, approval of such counsel by Indemnitee and the retention of such counsel
by the Company, the Company will not be liable to Indemnitee under this
Agreement for any fees of counsel subsequently incurred by Indemnitee with
respect to the same proceeding, provided that (i) Indemnitee shall have the
right to employ his counsel in any such proceeding at Indemnitee's expense; and
(ii) if (A) the employment of counsel by Indemnitee has been previously
authorized by the Company, (B) Indemnitee shall have reasonably concluded that
there may be a conflict of interest between the Company and Indemnitee in the
conduct of any such defense, or (C) the Company shall not, in fact, have
employed counsel to assume the defense of such proceeding, then the fees and
expenses of Indemnitee's counsel shall be at the expense of the Company.

     4.   Additional Indemnification Rights; Nonexclusivity.

          (a)  Scope. Notwithstanding any other provision of this Agreement, the
Company hereby agrees to indemnify the Indemnitee to the fullest extent
permitted by law, notwithstanding that such indemnification is not specifically
authorized by the other provisions of this Agreement, the Company's Certificate
of Incorporation, the Company's Bylaws or by statute. In the event of any
change, after the date of this Agreement, in any applicable law, statute, or
rule which expands the right of a Delaware corporation to indemnify a member of
its board of directors or an officer, such changes shall be, ipso facto, within
the purview of Indemnitee's rights and Company's obligations, under this
Agreement. In the event of any change in any applicable law, statute or rule
which narrows the right of a Delaware corporation to indemnify a member of its
board of directors or an officer, such changes, to the extent not otherwise
required by such law, statute or rule to be applied to this Agreement shall have
no effect on this Agreement or the parties' rights and obligations hereunder.

          (b)  Nonexclusivity. The indemnification provided by this Agreement
shall not be deemed exclusive of any rights to which Indemnitee may be entitled
under the Company's Certificate of Incorporation, its Bylaws, any agreement, any
vote of stockholders or disinterested Directors, the General Corporation Law of
the State of Delaware, or otherwise, both as to action in Indemnitee's official
capacity and as to action in another capacity while holding such office.  The
indemnification provided under this Agreement shall continue as to Indemnitee
for any action taken or not taken while serving in an indemnified capacity even
though he may have ceased to serve in such capacity at the time of any action,
suit or other covered proceeding.

                                      -4-
<PAGE>

     5.   Partial Indemnification. If Indemnitee is entitled under any provision
of this Agreement to indemnification by the Company for some or a portion of the
expenses, judgments, fines or penalties actually or reasonably incurred by him
in the investigation, defense, appeal or settlement of any civil or criminal
action, suit or proceeding, but not, however, for the total amount thereof, the
Company shall nevertheless indemnify Indemnitee for the portion of such
expenses, judgments, fines or penalties to which Indemnitee is entitled.

     6.   Mutual Acknowledgement. Both the Company and Indemnitee acknowledge
that in certain instances, Federal law or applicable public policy may prohibit
the Company from indemnifying its directors and officers under this Agreement or
otherwise. Indemnitee understands and acknowledges that the Company has
undertaken or may be required in the future to undertake with the Securities and
Exchange Commission to submit the question of indemnification to a court in
certain circumstances for a determination of the Company's right under public
policy to indemnify Indemnitee.

     7.   Officer and Director Liability Insurance. The Company shall, from time
to time, make the good faith determination whether or not it is practicable for
the Company to obtain and maintain a policy or policies of insurance with
reputable insurance companies providing the officers and directors of the
Company with coverage for losses from wrongful acts, or to ensure the Company's
performance of its indemnification obligations under this Agreement. Among other
considerations, the Company will weigh the costs of obtaining such insurance
coverage against the protection afforded by such coverage. In all policies of
director and officer liability insurance, Indemnitee shall be named as an
insured in such a manner as to provide Indemnitee the same rights and benefits
as are accorded to the most favorably insured of the Company's directors, if
Indemnitee is a director; or of the Company's officers, if Indemnitee is not a
director of the Company but is an officer. Notwithstanding the foregoing, the
Company shall have no obligation to obtain or maintain such insurance if the
Company determines in good faith that such insurance is not reasonably
available, if the premium costs for such insurance are disproportionate to the
amount of coverage provided, if the coverage provided by such insurance is
limited by exclusions so as to provide an insufficient benefit, or if Indemnitee
is covered by similar insurance maintained by a subsidiary or parent of the
Company.

     8.   Severability. Nothing in this Agreement is intended to require or
shall be construed as requiring the Company to do or fail to do any act in
violation of applicable law. The Company's inability, pursuant to court order,
to perform its obligations under this Agreement shall not constitute a breach of
this Agreement. The provisions of this Agreement shall be severable as provided
in this Section 8. If this Agreement or any portion hereof shall be invalidated
on any ground by any court of competent jurisdiction, then the Company shall
nevertheless indemnify Indemnitee to the full extent permitted by any applicable
portion of this Agreement that shall not have been invalidated, and the balance
of this Agreement not so invalidated shall be enforceable in accordance with its
terms.

                                      -5-

     9.   Exceptions. Any other provision herein to the contrary
notwithstanding, the Company shall not be obligated pursuant to the terms of
this Agreement:

          (a)  Claims Initiated by Indemnitee.  To indemnify or advance expenses
to Indemnitee with respect to proceedings or claims initiated or brought
voluntarily by Indemnitee and not by way of defense, except with respect to
proceedings brought to establish or enforce a right to indemnification under
this Agreement or any other statute or law or otherwise as required under
Section 145 of the Delaware General Corporation Law, but such indemnification or
advancement of expenses may be provided by the Company in specific cases if the
Board of Directors has approved the initiation or bringing of such suit; or

          (b)  Lack of Good Faith.  To indemnify Indemnitee for any expenses
incurred by the Indemnitee with respect to any proceeding instituted by
Indemnitee to enforce or interpret this Agreement, if a court of competent
jurisdiction determines that each of the material assertions made by the
Indemnitee in such proceeding was not made in good faith or was frivolous; or

          (c)  Insured Claims.  To indemnify Indemnitee for expenses or
liabilities of any type whatsoever (including, but not limited to, judgments,
fines, ERISA excise taxes or penalties, and amounts paid in settlement) which
have been paid directly to Indemnitee by an insurance carrier under a policy of
officers' and directors' liability insurance maintained by the Company.

          (d)  Claims Under Section 16(b).  To indemnify Indemnitee for expenses
and the payment of profits arising from the purchase and sale by Indemnitee of
securities in violation of Section 16(b) of the Securities Exchange Act of 1934,
as amended, or any similar successor statute.

          10.  Construction of Certain Phrases.

          (a)  For purposes of this Agreement, references to the "Company" shall
include, in addition to the resulting corporation, any constituent corporation
(including any constituent of a constituent) absorbed in a consolidation or
merger which, if its separate existence had continued, would have had power and
authority to indemnify its directors, officers, and employees or agents, so that
if Indemnitee is or was a director, officer, employee or agent of such
constituent corporation, or is or was serving at the request of such constituent
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, Indemnitee shall stand in
the same position under the provisions of this Agreement with respect to the
resulting or surviving corporation as Indemnitee would have with respect to such
constituent corporation if its separate existence had continued.

          (b)  For purposes of this Agreement, references to "other enterprises"
shall include employee benefit plans; references to "fines" shall include any
excise taxes assessed on Indemnitee with respect to an employee benefit plan;
and references to "serving at the request of the Company" shall include any
service as a director, officer, employee or agent of the Company which imposes
duties on, or involves services by, such director, officer, employee or agent
with respect to an employee benefit plan, its participants, or beneficiaries;
and if Indemnitee acted in good faith and in a manner Indemnitee reasonably
believed to be in the interest of the participants and beneficiaries of

                                      -6-
<PAGE>

an employee benefit plan, Indemnitee shall be deemed to have acted in a manner
"not opposed to the best interests of the Company" as referred to in this
Agreement.

     11.  Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall constitute an original.

     12.  Successors and Assigns. This Agreement shall be binding upon the
Company and its successors and assigns, and shall inure to the benefit of
Indemnitee and Indemnitee's estate, heirs, legal representatives and assigns.

     13.  Attorneys' Fees.  In the event that any action is instituted by
Indemnitee under this Agreement to enforce or interpret any of the terms hereof,
Indemnitee shall be entitled to be paid all court costs and expenses, including
reasonable attorneys' fees, incurred by Indemnitee with respect to such action,
unless as a part of such action, the court of competent jurisdiction determines
that each of the material assertions made by Indemnitee as a basis for such
action were not made in good faith or were frivolous.  In the event of an action
instituted by or in the name of the Company under this Agreement or to enforce
or interpret any of the terms of this Agreement, Indemnitee shall be entitled to
be paid all court costs and expenses, including attorneys' fees, incurred by
Indemnitee in defense of such action (including with respect to Indemnitee's
counterclaims and cross-claims made in such action), unless as a part of such
action the court determines that each of Indemnitee's material defenses to such
action were made in bad faith or were frivolous.

     14.  Notice. All notices, requests, demands and other communications under
this Agreement shall be in writing and shall be deemed duly given (i) if
delivered by hand and receipted for by the party addressee, on the date of such
receipt, or (ii) if mailed by domestic certified or registered mail with postage
prepaid, on the third business day after the date postmarked. Addresses for
notice to either party are as shown on the signature page of this Agreement, or
as subsequently modified by written notice.

     15.  Consent to Jurisdiction.  The Company and Indemnitee each hereby
irrevocably consent to the jurisdiction of the courts of the State of Delaware
for all purposes in connection with any action or proceeding which arises out of
or relates to this Agreement and agree that any action instituted under this
Agreement shall be brought only in the state courts of the State of Delaware.

     16.  Choice of Law. This Agreement shall be governed by and its provisions
construed in accordance with the laws of the State of Delaware, as applied to
contracts between Delaware residents entered into and to be performed entirely
within Delaware without regard to the conflict of law principles thereof.

     17.  Period of Limitations.  No legal action shall be brought and no
cause of action shall be asserted by or in the right of the Company against
Indemnitee, Indemnitee's estate, spouse, heirs, executors or personal or legal
representatives after the expiration of two years from the date of accrual of
such cause of action, and any claim or cause of action of the Company shall be
extinguished and deemed released unless asserted by the timely filing of a legal
action within such

                                      -7-
<PAGE>

two-year period; provided, however, that if any shorter period of limitations is
                 --------  -------
otherwise applicable to any such cause of action, such shorter period shall
govern.

     18.  Subrogation. In the event of payment under this Agreement, the Company
shall be subrogated to the extent of such payment to all of the rights of
recovery of Indemnitee, who shall execute all documents required and shall do
all acts that may be necessary to secure such rights and to enable the Company
effectively to bring suit to enforce such rights.

     19.  Amendment and Termination. No amendment, modification, termination or
cancellation of this Agreement shall be effective unless it is in writing signed
by both the parties hereto. No waiver of any of the provisions of this Agreement
shall be deemed or shall constitute a waiver of any other provisions hereof
(whether or not similar) nor shall such waiver constitute a continuing waiver.

     20.  Integration and Entire Agreement.  This Agreement sets forth the
entire understanding between the parties hereto and supersedes and merges all
previous written and oral negotiations, commitments, understandings and
agreements relating to the subject matter hereof between the parties hereto.

                                      -8-

SECTION 1.  Establishment And Purpose.

     The purpose of the Plan is to offer selected individuals an opportunity to
acquire a proprietary interest in the success of the Company, or to increase
such interest, by purchasing Shares of the Company's Stock.  The Plan provides
both for the direct award or sale of Shares and for the grant of Options to
purchase Shares.  Options granted under the Plan may include Nonstatutory
Options as well as ISOs intended to qualify under Section 422 of the Code.

     Capitalized terms are defined in Section 12.

SECTION 2.  Administration.

     (a)  Committees of the Board of Directors.    The Plan may be administered
by one or more Committees.  Each Committee shall consist of one or more members
of the Board of Directors who have been appointed by the Board of Directors.
Each Committee shall have such authority and be responsible for such functions
as the Board of Directors has assigned to it.  If no Committee has been
appointed, the entire Board of Directors shall administer the Plan.  Any
reference to the Board of Directors in the Plan shall be construed as a
reference to the Committee (if any) to whom the Board of Directors has assigned
a particular function.

     (b)  Authority of the Board of Directors.    Subject to the provisions of
the Plan, the Board of Directors shall have full authority and discretion to
take any actions it deems necessary or advisable for the administration of the
Plan.  All decisions, interpretations and other actions of the Board of
Directors shall be final and binding on all Purchasers, all Optionees and all
persons deriving their rights from a Purchaser or Optionee.

SECTION 3.  Eligibility.

     (a)  General Rule.    Only Employees, Outside Directors and Consultants
shall be eligible for the grant of Options or the direct award or sale of
Shares.  Only Employees shall be eligible for the grant of ISOs.

     (b)  Ten-Percent Stockholders.    An individual who owns more than 10% of
the total combined voting power of all classes of outstanding stock of the
Company, its Parent or any of its Subsidiaries shall not be eligible for
designation as an Optionee or Purchaser unless (i) the Exercise Price is at
least 110% of the Fair Market Value of a Share on the date of grant, (ii) the
Purchase Price (if any) is at least 100% of the Fair Market Value of a Share and
(iii) in the case of an ISO, such ISO by its terms is not exercisable after the
expiration of five years from the date of grant.  For purposes of this
Subsection (b), in determining stock ownership, the attribution rules of Section
424(d) of the Code shall be applied.

SECTION 4.  Stock Subject To Plan.

     (a)  Basic Limitation.    Shares offered under the Plan may be authorized
but unissued Shares or treasury Shares.  The aggregate number of Shares that may
be issued under the Plan (upon exercise of Options or other rights to acquire
Shares) shall not exceed 2,334,875/1/ Shares, subject to adjustment pursuant to
Section 8.  The number of Shares that are subject to Options or other rights
outstanding at any time under the Plan shall not exceed the number of Shares
that then remain available for issuance under the Plan.  The Company, during the
term of the Plan, shall at all times reserve and keep available sufficient
Shares to satisfy the requirements of the Plan.

     (b)  Additional Shares.    In the event that any outstanding Option or
other right for any reason expires or is canceled or otherwise terminated, the
Shares allocable to the unexercised portion of such Option or other right shall
again be available for the purposes of the Plan.  In the event that Shares
issued under the Plan are reacquired by the Company pursuant to any forfeiture
provision, right of repurchase or right of first refusal, such Shares shall
again be available for the purposes of the Plan, except that the aggregate
number of Shares which may be issued upon the exercise of ISOs shall in no event
exceed 3,334,875 Shares (subject to adjustment pursuant to Section 8).

SECTION 5.  Terms And Conditions Of Awards Or Sales.

     (a)  Stock Purchase Agreement.    Each award or sale of Shares under the
Plan (other than upon exercise of an Option) shall be evidenced by a Stock
Purchase Agreement between the Purchaser and the Company.  Such award or sale
shall be subject to all applicable terms and conditions of the Plan and may be
subject to any other terms and conditions which are not inconsistent with the
Plan and which the Board of Directors deems appropriate for inclusion in a Stock
Purchase Agreement.  The provisions of the various Stock Purchase Agreements
entered into under the Plan need not be identical.

     (b)  Duration of Offers and Nontransferability of Rights.    Any right to
acquire Shares under the Plan (other than an Option) shall automatically expire
if not exercised by the Purchaser within 30 days after the grant of such right
was communicated to the Purchaser by the Company.  Such right shall not be
transferable and shall be exercisable only by the Purchaser to whom such right
was granted.

     (d)  Withholding Taxes.    As a condition to the purchase of Shares, the
Purchaser shall make such arrangements as the Board of Directors may require for
the satisfaction of any federal, state, local or foreign withholding tax
obligations that may arise in connection with such purchase.

     (e)  Restrictions on Transfer of Shares and Minimum Vesting.    Any Shares
awarded or sold under the Plan shall be subject to such special forfeiture
conditions, rights of repurchase, rights of first refusal and other transfer
restrictions as the Board of Directors may determine.  Such restrictions shall
be set forth in the applicable Stock Purchase Agreement and shall apply in
addition to any restrictions that may apply to holders of Shares generally.  In
the case of a Purchaser who is not an officer of the Company, an Outside
Director or a Consultant, any right to repurchase the Purchaser's Shares at the
original Purchase Price (if any) upon termination of the Purchaser's Service
shall lapse at least as rapidly as 20% per year over the five-year period
commencing on the date of the award or sale of the Shares.  Any such right may
be exercised only within 90 days after the termination of the Purchaser's
Service for cash or for cancellation of indebtedness incurred in purchasing the
Shares.

     (f) Accelerated Vesting.  Unless the applicable Stock Purchase Agreement
provides otherwise, any right to repurchase a Purchaser's Shares at the original
Purchase Price (if any) upon termination of the Purchaser's Service shall lapse
and all of such Shares shall become vested if (i) the Company is subject to a
Change in Control before the Purchaser's Service terminates and (ii) the
repurchase right is not assigned to the entity that employs the Purchaser
immediately after the Change in Control or to its parent or subsidiary.

SECTION 6.  Terms And Conditions Of Options.

     (a)  Stock Option Agreement.    Each grant of an Option under the Plan
shall be evidenced by a Stock Option Agreement between the Optionee and the
Company.  Such Option shall be subject to all applicable terms and conditions of
the Plan and may be subject to any other terms and conditions which are not
inconsistent with the Plan and which the Board of Directors deems appropriate
for inclusion in a Stock Option Agreement.  The provisions of the various Stock
Option Agreements entered into under the Plan need not be identical.

     (b)  Number of Shares.    Each Stock Option Agreement shall specify the
number of Shares that are subject to the Option and shall provide for the
adjustment of such number in accordance with Section 8.  The Stock Option
Agreement shall also specify whether the Option is an ISO or a Nonstatutory
Option.

     (c)  Exercise Price.    Each Stock Option Agreement shall specify the
Exercise Price.  The Exercise Price of an ISO shall not be less than 100% of the
Fair Market Value of a Share on the date of grant, and a higher percentage may
be required by Section 3(b).  The Exercise Price of a Nonstatutory Option shall
not be less than 85% of the Fair Market Value of a Share on the date of grant,
and a higher percentage may be required by Section 3(b).  Subject to the
preceding two sentences, the Exercise Price under any Option shall be determined

<PAGE>

     (d)  Withholding Taxes.    As a condition to the exercise of an Option, the
Optionee shall make such arrangements as the Board of Directors may require for
the satisfaction of any federal, state, local or foreign withholding tax
obligations that may arise in connection with such exercise.  The Optionee shall
also make such arrangements as the Board of Directors may require for the
satisfaction of any federal, state, local or foreign withholding tax obligations
that may arise in connection with the disposition of Shares acquired by
exercising an Option.

     (e)  Exercisability.    Each Stock Option Agreement shall specify the date
when all or any installment of the Option is to become exercisable.  In the case
of an Optionee who is not an officer of the Company, an Outside Director or a
Consultant, an Option shall become exercisable at least as rapidly as 20% per
year over the five-year period commencing on the date of grant.  Subject to the
preceding sentence, the exercisability provisions of any Stock Option Agreement
shall be determined by the Board of Directors at its sole discretion.

     (f) Accelerated Exercisability.  Unless the applicable Stock Option
Agreement provides otherwise, all of an Optionee's Options shall become
exercisable in full if (i) the Company is subject to a Change in Control before
the Optionee's Service terminates, (ii) such Options do not remain outstanding,
(iii) such Options are not assumed by the surviving corporation or its parent
and (iv) the surviving corporation or its parent does not substitute options
with substantially the same terms for such Options.

     (g)  Basic Term.    The Stock Option Agreement shall specify the term of
the Option.  The term shall not exceed 10 years from the date of grant, and a
shorter term may be required by Section 3(b).  Subject to the preceding
sentence, the Board of Directors at its sole discretion shall determine when an
Option is to expire.

     (h)  Nontransferability.    No Option shall be transferable by the Optionee
other than by beneficiary designation, will or the laws of descent and
distribution.  An Option may be exercised during the lifetime of the Optionee
only by the Optionee or by the Optionee's guardian or legal representative.  No
Option or interest therein may be transferred, assigned, pledged or hypothecated
by the Optionee during the Optionee's lifetime, whether by operation of law or
otherwise, or be made subject to execution, attachment or similar process.

     (i)  Termination of Service (Except by Death).    If an Optionee's Service
terminates for any reason other than the Optionee's death, then the Optionee's
Options shall expire on the earliest of the following occasions:

          (i)   The expiration date determined pursuant to Subsection (g) above;

          (ii)  The date three months after the termination of the Optionee's
     Service for any reason other than Disability, or such later date as the
     Board of Directors may determine; or

          (iii) The date six months after the termination of the Optionee's
     Service by reason of Disability, or such later date as the Board of
     Directors may determine.

                                       4
<PAGE>

The Optionee may exercise all or part of the Optionee's Options at any time
before the expiration of such Options under the preceding sentence, but only to
the extent that such Options had become exercisable before the Optionee's
Service terminated (or became exercisable as a result of the termination) and
the underlying Shares had vested before the Optionee's Service terminated (or
vested as a result of the termination).  The balance of such Options shall lapse
when the Optionee's Service terminates.  In the event that the Optionee dies
after the termination of the Optionee's Service but before the expiration of the
Optionee's Options, all or part of such Options may be exercised (prior to
expiration) by the executors or administrators of the Optionee's estate or by
any person who has acquired such Options directly from the Optionee by
beneficiary designation, bequest or inheritance, but only to the extent that
such Options had become exercisable before the Optionee's Service terminated (or
became exercisable as a result of the termination) and the underlying Shares had
vested before the Optionee's Service terminated (or vested as a result of the
termination).

     (j)  Leaves of Absence.    For purposes of Subsection (i) above, Service
shall be deemed to continue while the Optionee is on a bona fide leave of
absence, if such leave was approved by the Company in writing and if continued
crediting of Service for this purpose is expressly required by the terms of such
leave or by applicable law (as determined by the Company).

     (k)  Death of Optionee.    If an Optionee dies while the Optionee is in
Service, then the Optionee's Options shall expire on the earlier of the
following dates:

          (i)  The expiration date determined pursuant to Subsection (g) above;
     or

          (ii) The date 12 months after the Optionee's death.

All or part of the Optionee's Options may be exercised at any time before the
expiration of such Options under the preceding sentence by the executors or
administrators of the Optionee's estate or by any person who has acquired such
Options directly from the Optionee by beneficiary designation, bequest or
inheritance, but only to the extent that such Options had become exercisable
before the Optionee's death or became exercisable as a result of the death.  The
balance of such Options shall lapse when the Optionee dies.

     (l)  No Rights as a Stockholder.    An Optionee, or a transferee of an
Optionee, shall have no rights as a stockholder with respect to any Shares
covered by the Optionee's Option until such person becomes entitled to receive
such Shares by filing a notice of exercise and paying the Exercise Price
pursuant to the terms of such Option.

     (m)  Modification, Extension and Assumption of Options.    Within the
limitations of the Plan, the Board of Directors may modify, extend or assume
outstanding Options or may accept the cancellation of outstanding Options
(whether granted by the Company or another issuer) in return for the grant of
new Options for the same or a different number of Shares and at the same or a
different Exercise Price.  The foregoing notwithstanding, no modification of an

                                       5
<PAGE>

Option shall, without the consent of the Optionee, impair the Optionee's rights
or increase the Optionee's obligations under such Option.

     (n)  Restrictions on Transfer of Shares and Minimum Vesting.    Any Shares
issued upon exercise of an Option shall be subject to such special forfeiture
conditions, rights of repurchase, rights of first refusal and other transfer
restrictions as the Board of Directors may determine.  Such restrictions shall
be set forth in the applicable Stock Option Agreement and shall apply in
addition to any restrictions that may apply to holders of Shares generally.  In
the case of an Optionee who is not an officer of the Company, an Outside
Director or a Consultant, any right to repurchase the Optionee's Shares at the
original Exercise Price upon termination of the Optionee's Service shall lapse
at least as rapidly as 20% per year over the five-year period commencing on the
date of the option grant.  Any such repurchase right may be exercised only
within 90 days after the termination of the Optionee's Service for cash or for
cancellation of indebtedness incurred in purchasing the Shares.

     (o) Accelerated Vesting.  Unless the applicable Stock Option Agreement
provides otherwise, any right to repurchase an Optionee's Shares at the original
Exercise Price upon termination of the Optionee's Service shall lapse and all of
such Shares shall become vested if (i) the Company is subject to a Change in
Control before the Optionee's Service terminates and (ii) the repurchase right
is not assigned to the entity that employs the Optionee immediately after the
Change in Control or to its parent or subsidiary.

SECTION 7.  Payment For Shares.

     (a)  General Rule.    The entire Purchase Price or Exercise Price of Shares
issued under the Plan shall be payable in cash or cash equivalents at the time
when such Shares are purchased, except as otherwise provided in this Section 7.

     (b)  Surrender of Stock.    To the extent that a Stock Option Agreement so
provides, all or any part of the Exercise Price may be paid by surrendering, or
attesting to the ownership of, Shares that are already owned by the Optionee.
Such Shares shall be surrendered to the Company in good form for transfer and
shall be valued at their Fair Market Value on the date when the Option is
exercised.  The Optionee shall not surrender, or attest to the ownership of,
Shares in payment of the Exercise Price if such action would cause the Company
to recognize compensation expense (or additional compensation expense) with
respect to the Option for financial reporting purposes.

     (c)  Services Rendered.    At the discretion of the Board of Directors,
Shares may be awarded under the Plan in consideration of services rendered to
the Company, a Parent or a Subsidiary prior to the award.  At the discretion of
the Board of Directors, Shares may also be awarded under the Plan in
consideration of services to be rendered to the Company, a Parent or a
Subsidiary after the award, except that the par value of such Shares, if newly
issued, shall be paid in cash or cash equivalents.

     (d)  Promissory Note.    To the extent that a Stock Option Agreement or
Stock Purchase Agreement so provides, all or a portion of the Exercise Price or
Purchase Price (as the

                                       6
<PAGE>

case may be) of Shares issued under the Plan may be paid with a full-recourse
promissory note. However, the par value of the Shares, if newly issued, shall be
paid in cash or cash equivalents. The Shares shall be pledged as security for
payment of the principal amount of the promissory note and interest thereon. The
interest rate payable under the terms of the promissory note shall not be less
than the minimum rate (if any) required to avoid the imputation of additional
interest under the Code. Subject to the foregoing, the Board of Directors (at
its sole discretion) shall specify the term, interest rate, amortization
requirements (if any) and other provisions of such note.

     (e)  Exercise/Sale.    To the extent that a Stock Option Agreement so
provides, and if Stock is publicly traded, payment may be made all or in part by
the delivery (on a form prescribed by the Company) of an irrevocable direction
to a securities broker approved by the Company to sell Shares and to deliver all
or part of the sales proceeds to the Company in payment of all or part of the
Exercise Price and any withholding taxes.

     (f)  Exercise/Pledge.    To the extent that a Stock Option Agreement so
provides, and if Stock is publicly traded, payment may be made all or in part by
the delivery (on a form prescribed by the Company) of an irrevocable direction
to pledge Shares to a securities broker or lender approved by the Company, as
security for a loan, and to deliver all or part of the loan proceeds to the
Company in payment of all or part of the Exercise Price and any withholding
taxes.

SECTION 8.  Adjustment Of Shares.

     (a)  General.    In the event of a subdivision of the outstanding Stock, a
declaration of a dividend payable in Shares, a declaration of an extraordinary
dividend payable in a form other than Shares in an amount that has a material
effect on the Fair Market Value of the Stock, a combination or consolidation of
the outstanding Stock into a lesser number of Shares, a recapitalization, a
spin-off, a reclassification or a similar occurrence, the Board of Directors
shall make appropriate adjustments in one or more of (i) the number of Shares
available for future grants under Section 4, (ii) the number of Shares covered
by each outstanding Option or (iii) the Exercise Price under each outstanding
Option.

     (b)  Mergers and Consolidations.    In the event that the Company is a
party to a merger or consolidation, outstanding Options shall be subject to the
agreement of merger or consolidation.  Such agreement, without the Optionees'
consent, may provide for:

          (i)   The continuation of such outstanding Options by the Company (if
     the Company is the surviving corporation);

          (ii)  The assumption of the Plan and such outstanding Options by the
     surviving corporation or its parent;

          (iii) The substitution by the surviving corporation or its parent of
     options with substantially the same terms for such outstanding Options; or

                                       7
<PAGE>

          (iv)  The cancellation of such outstanding Options without payment of
     any consideration.

     (c)  Reservation of Rights.    Except as provided in this Section 8, an
Optionee or Purchaser shall have no rights by reason of (i) any subdivision or
consolidation of shares of stock of any class, (ii) the payment of any dividend
or (iii) any other increase or decrease in the number of shares of stock of any
class.  Any issuance by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall not affect, and
no adjustment by reason thereof shall be made with respect to, the number or
Exercise Price of Shares subject to an Option.  The grant of an Option pursuant
to the Plan shall not affect in any way the right or power of the Company to
make adjustments, reclassifications, reorganizations or changes of its capital
or business structure, to merge or consolidate or to dissolve, liquidate, sell
or transfer all or any part of its business or assets.

SECTION 9.  Securities Law Requirements.

     (a) General.  Shares shall not be issued under the Plan unless the issuance
and delivery of such Shares comply with (or are exempt from) all applicable
requirements of law, including (without limitation) the Securities Act of 1933,
as amended, the rules and regulations promulgated thereunder, state securities
laws and regulations, and the regulations of any stock exchange or other
securities market on which the Company's securities may then be traded.

     (b)  Financial Reports.    The Company each year shall furnish to
Optionees, Purchasers and stockholders who have received Stock under the Plan
its balance sheet and income statement, unless such Optionees, Purchasers or
stockholders are key Employees whose duties with the Company assure them access
to equivalent information.  Such balance sheet and income statement need not be
audited.

SECTION 10.    No Retention Rights.

     Nothing in the Plan or in any right or Option granted under the Plan shall
confer upon the Purchaser or Optionee any right to continue in Service for any
period of specific duration or interfere with or otherwise restrict in any way
the rights of the Company (or any Parent or Subsidiary employing or retaining
the Purchaser or Optionee) or of the Purchaser or Optionee, which rights are
hereby expressly reserved by each, to terminate his or her Service at any time
and for any reason, with or without cause.

SECTION 11.    Duration and Amendments.

     (a)  Term of the Plan.    The Plan, as set forth herein, shall become
effective on the date of its adoption by the Board of Directors, subject to the
approval of the Company's stockholders.  In the event that the stockholders fail

ISOs, shall be subject to the approval of the Company's stockholders.
Stockholder approval shall not be required for any other amendment of the Plan.

     (c)  Effect of Amendment or Termination.    No Shares shall be issued or
sold under the Plan after the termination thereof, except upon exercise of an

               iBEAM BROADCASTING CORPORATION 1998 STOCK PLAN:

                          STOCK PURCHASE AGREEMENT

SECTION 1.   ACQUISITION OF SHARES.

        (a)  Transfer. On the terms and conditions set forth in the Summary of
Stock Purchase and this Agreement, the Company agrees to transfer to the
Purchaser the number of Shares set forth in the Summary of Stock Purchase. The
transfer shall occur at the offices of the Company on the date of purchase set
forth in the Summary of Stock Purchase or at such other place and time as the
parties may agree.

        (b)  Consideration. The Purchaser agrees to pay the Purchase Price set
forth in the Summary of Stock Purchase for each Purchased Share. The Purchase
Price is agreed to be at least 100% of the Fair Market Value of the Purchased
Shares. Payment shall be made on the transfer date in cash or cash
equivalents.

        (c)  Stock Plan and Defined Terms. The transfer of the Purchased
Shares is subject to the Plan, a copy of which the Purchaser acknowledges
having received. The provisions of the Plan are incorporated into this
Agreement by this reference. Capitalized terms are defined in Section 12 of
this Agreement.

SECTION 2.   RIGHT OF REPURCHASE.

        (a)  Scope of Repurchase Right. All Purchased Shares initially shall
be Restricted Shares and shall be subject to a right (but not an obligation)
of repurchase by the Company. The Purchaser shall not transfer, assign,
encumber or otherwise dispose of any Restricted Shares, except as provided in
the following sentence. The Purchaser may transfer Restricted Shares (i) by
beneficiary designation, will or intestate succession or (ii) to the
Purchaser's spouse, children or grandchildren or to a trust established by the
Purchaser for the benefit of the Purchaser or the Purchaser's spouse, children
or grandchildren, provided in either case that the Transferee agrees in
writing on a form prescribed by the Company to be bound by all provisions of
this Agreement. If the Purchaser transfers any Restricted Shares, then this
Section 2 shall apply to the Transferee to the same extent as to the
Purchaser.

        (b)  Condition Precedent to Exercise. The Right of Repurchase shall be
exercisable only during the 60-day period next following the date when the
Purchaser's Service terminates for any reason, with or without cause,
including (without limitation) death or disability.

        (c)  Lapse of Repurchase Right. The Right of Repurchase shall lapse
with respect to the Purchased Shares in accordance with the vesting schedule
set forth in the Summary of Stock Purchase. In addition, the Right of
Repurchase shall lapse and all of the remaining
<PAGE>

Restricted Shares shall become vested if (i) the Company is subject to a
Change in Control before the Purchaser's Service terminates and (ii) the Right
of Repurchase is not assigned to the entity that employs the Purchaser
immediately after the Change in Control or to its parent or subsidiary.

        (d)  Repurchase Cost. If the Company exercises the Right of
Repurchase, it shall pay the Purchaser an amount equal to the Purchase Price
for each of the Restricted Shares being repurchased.

        (e) Exercise of Repurchase Right. The Right of Repurchase shall be
exercisable only by written notice delivered to the Purchaser prior to the
expiration of the 60-day period specified in Subsection (b) above. The notice
shall set forth the date on which the repurchase is to be effected. Such date
shall not be more than 30 days after the date of the notice. The
certificate(s) representing the Restricted Shares to be repurchased shall,
prior to the close of business on the date specified for the repurchase, be
delivered to the Company properly endorsed for transfer. The Company shall,
concurrently with the receipt of such certificate(s), pay to the Purchaser the
purchase price determined according to Subsection (d) above. Payment shall be
made in cash or cash equivalents or by canceling indebtedness to the Company
incurred by the Purchaser in the purchase of the Restricted Shares. The Right
of Repurchase shall terminate with respect to any Restricted Shares for which
it has not been timely exercised pursuant to this Subsection (e).

        (f) Additional Shares or Substituted Securities. In the event of the
declaration of a stock dividend, the declaration of an extraordinary dividend
payable in a form other than stock, a spin-off, a stock split, an adjustment
in conversion ratio, a recapitalization or a similar transaction affecting the
Company's outstanding securities without receipt of consideration, any new,
substituted or additional securities or other property (including money paid
other than as an ordinary cash dividend) which are by reason of such
transaction distributed with respect to any Restricted Shares or into which
such Restricted Shares thereby become convertible shall immediately be subject
to the Right of Repurchase. Appropriate adjustments to reflect the
distribution of such securities or property shall be made to the number and/or
class of the Restricted Shares. Appropriate adjustments shall also, after each
such transaction, be made to the price per share to be paid upon the exercise
of the Right of Repurchase in order to reflect any change in the Company's
outstanding securities effected without receipt of consideration therefor;
provided, however, that the aggregate purchase price payable for the
Restricted Shares shall remain the same.

        (g) Termination of Rights as Stockholder. If the Company makes
available, at the time and place and in the amount and form provided in this
Agreement, the consideration for the Restricted Shares to be repurchased in
accordance with this Section 2, then after such time the person from whom such
Restricted Shares are to be repurchased shall no longer have any rights as a
holder of such Restricted Shares (other than the right to receive payment of
such consideration in accordance with this Agreement). Such Restricted Shares
shall be deemed to have been repurchased in accordance with the applicable
provisions hereof, whether or not the certificate(s) therefor have been
delivered as required by this Agreement.

                                      2
<PAGE>

        (h) Escrow. Upon issuance, the certificates for Restricted Shares
shall be deposited in escrow with the Company to be held in accordance with
the provisions of this Agreement. Any new, substituted or additional
securities or other property described in Subsection (f) above shall
immediately be delivered to the Company to be held in escrow, but only to the
extent the Purchased Shares are at the time Restricted Shares. All regular
cash dividends on Restricted Shares (or other securities at the time held in
escrow) shall be paid directly to the Purchaser and shall not be held in
escrow. Restricted Shares, together with any other assets or securities held
in escrow hereunder, shall be (i) surrendered to the Company for repurchase
and cancellation upon the Company's exercise of its Right of Repurchase or
Right of First Refusal or (ii) released to the Purchaser upon the Purchaser's
request to the extent the Purchased Shares are no longer Restricted Shares
(but not more frequently than once every six months). In any event, all
Purchased Shares which have vested (and any other vested assets and securities
attributable thereto) shall be released within 60 days after the earlier of
(i) the Purchaser's cessation of Service or (ii) the lapse of the Right of
First Refusal.

SECTION 3.   RIGHT OF FIRST REFUSAL.

        (a) Right of First Refusal. In the event that the Purchaser proposes
to sell, pledge or otherwise transfer to a third party any Purchased Shares,
or any interest in such Purchased Shares, the Company shall have the Right of
First Refusal with respect to all (and not less than all) of such Purchased
Shares. If the Purchaser desires to transfer Purchased Shares, the Purchaser
shall give a written Transfer Notice to the Company describing fully the
proposed transfer, including the number of Purchased Shares proposed to be
transferred, the proposed transfer price, the name and address of the proposed
Transferee and proof satisfactory to the Company that the proposed sale or
transfer will not violate any applicable federal or state securities laws. The
Transfer Notice shall be signed both by the Purchaser and by the proposed
Transferee and must constitute a binding commitment of both parties to the
transfer of the Purchased Shares. The Company shall have the right to purchase
all, and not less than all, of the Purchased Shares on the terms of the
proposal described in the Transfer Notice (subject, however, to any change in
such terms permitted under Subsection (b) below) by delivery of a notice of
exercise of the Right of First Refusal within 30 days after the date when the
Transfer Notice was received by the Company. The Company's rights under this
Subsection (a) shall be freely assignable, in whole or in part.

        (b) Transfer of Shares. If the Company fails to exercise its Right of
First Refusal within 30 days after the date when it received the Transfer
Notice, the Purchaser may, not later than 90 days following receipt of the
Transfer Notice by the Company, conclude a transfer of the Purchased Shares
subject to the Transfer Notice on the terms and conditions described in the
Transfer Notice, provided that any such sale is made in compliance with
applicable federal and state securities laws and not in violation of any other
contractual restrictions to which the Purchaser is bound. Any proposed
transfer on terms and conditions different from those described in the
Transfer Notice, as well as any subsequent proposed transfer by the Purchaser,
shall again be subject to the Right of First Refusal and shall require
compliance with the procedure described in Subsection (a) above. If the
Company exercises its Right of First Refusal, the parties shall consummate the
sale of the Purchased Shares on the terms set forth in the Transfer Notice
within 60 days after the date when the Company received

                                      3
<PAGE>

the Transfer Notice (or within such longer period as may have been specified
in the Transfer Notice); provided, however, that in the event the Transfer
Notice provided that payment for the Purchased Shares was to be made in a form
other than cash or cash equivalents paid at the time of transfer, the Company
shall have the option of paying for the Purchased Shares with cash or cash
equivalents equal to the present value of the consideration described in the
Transfer Notice.

        (c) Additional Shares or Substituted Securities. In the event of the
declaration of a stock dividend, the declaration of an extraordinary dividend
payable in a form other than stock, a spin-off, a stock split, an adjustment
in conversion ratio, a recapitalization or a similar transaction affecting the
Company's outstanding securities without receipt of consideration, any new,
substituted or additional securities or other property (including money paid
other than as an ordinary cash dividend) which are by reason of such
transaction distributed with respect to any Purchased Shares subject to this
Section 3 or into which such Purchased Shares thereby become convertible shall
immediately be subject to this Section 3. Appropriate adjustments to reflect
the distribution of such securities or property shall be made to the number
and/or class of Purchased Shares subject to this Section 3.

        (d) Termination of Right of First Refusal. Any other provision of this
Section 3 notwithstanding, in the event that the Stock is readily tradable on
an established securities market when the Purchaser desires to transfer
Purchased Shares, the Company shall have no Right of First Refusal, and the
Purchaser shall have no obligation to comply with the procedures prescribed by
Subsections (a) and (b) above.

        (e) Permitted Transfers. This Section 3 shall not apply to (i) a
transfer by beneficiary designation, will or intestate succession or (ii) a
transfer to the Purchaser's spouse, children or grandchildren or to a trust
established by the Purchaser for the benefit of the Purchaser or the
Purchaser's spouse, children or grandchildren, provided in either case that
the Transferee agrees in writing on a form prescribed by the Company to be
bound by all provisions of this Agreement. If the Purchaser transfers any
Purchased Shares, either under this Subsection (e) or after the Company has
failed to exercise the Right of First Refusal, then this Section 3 shall apply
to the Transferee to the same extent as to the Purchaser.

        (f) Termination of Rights as Stockholder. If the Company makes
available, at the time and place and in the amount and form provided in this
Agreement, the consideration for the Purchased Shares to be purchased in
accordance with this Section 3, then after such time the person from whom such
Purchased Shares are to be purchased shall no longer have any rights as a
holder of such Purchased Shares (other than the right to receive payment of
such consideration in accordance with this Agreement). Such Purchased Shares
shall be deemed to have been purchased in accordance with the applicable
provisions hereof, whether or not the certificate(s) therefor have been
delivered as required by this Agreement.

SECTION 4.   OTHER RESTRICTIONS ON TRANSFER.

        (a) Purchaser Representations. In connection with the issuance and
acquisition of Shares under this Agreement, the Purchaser hereby represents
and warrants to the Company as follows:

                                      4
<PAGE>

        (i)    The Purchaser is acquiring and will hold the Purchased Shares
for investment for his or her account only and not with a view to, or for
resale in connection with, any "distribution" thereof within the meaning of
the Securities Act.

        (ii)   The Purchaser understands that the Purchased Shares have not
been registered under the Securities Act by reason of a specific exemption
therefrom and that the Purchased Shares must be held indefinitely, unless they
are subsequently registered under the Securities Act or the Purchaser obtains
an opinion of counsel, in form and substance satisfactory to the Company and
its counsel, that such registration is not required. The Purchaser further
acknowledges and understands that the Company is under no obligation to
register the Purchased Shares.

        (iii)  The Purchaser is aware of the adoption of Rule 144 by the
Securities and Exchange Commission under the Securities Act, which permits
limited public resales of securities acquired in a non-public offering,
subject to the satisfaction of certain conditions, including (without
limitation) the availability of certain current public information about the
issuer, the resale occurring only after the holding period required by Rule
144 has been satisfied, the sale occurring through an unsolicited "broker's
transaction," and the amount of securities being sold during any three-month
period not exceeding specified limitations. The Purchaser acknowledges and
understands that the conditions for resale set forth in Rule 144 have not been
satisfied and that the Company has no plans to satisfy these conditions in the
foreseeable future.

        (iv)   The Purchaser will not sell, transfer or otherwise dispose of
the Purchased Shares in violation of the Securities Act, the Securities
Exchange Act of 1934, or the rules promulgated thereunder, including Rule 144
under the Securities Act. The Purchaser agrees that he or she will not dispose
of the Purchased Shares unless and until he or she has complied with all
requirements of this Agreement applicable to the disposition of Purchased
Shares and he or she has provided the Company with written assurances, in
substance and form satisfactory to the Company, that (A) the proposed
disposition does not require registration of the Purchased Shares under the
Securities Act or all appropriate action necessary for compliance with the
registration requirements of the Securities Act or with any exemption from
registration available under the Securities Act (including Rule 144) has been
taken and (B) the proposed disposition will not result in the contravention of
any transfer restrictions applicable to the Purchased Shares under the Rules
of the California Corporations Commissioner.

        (v)    The Purchaser has been furnished with, and has had access to,
such information as he or she considers necessary or appropriate for deciding
whether to invest in the Purchased Shares, and the Purchaser has had an
opportunity to ask questions and receive answers from the Company regarding
the terms and conditions of the issuance of the Purchased Shares.

        (vi)   The Purchaser is aware that his or her investment in the
Company is a speculative investment which has limited liquidity and is subject
to the risk of complete loss. The Purchaser is able, without impairing his or
her financial condition, to hold the

                                      5
<PAGE>

Purchased Shares for an indefinite period and to suffer a complete loss of his
or her investment in the Purchased Shares.

        (b) Securities Law Restrictions. Regardless of whether the offering
and sale of Shares under the Plan have been registered under the Securities
Act or have been registered or qualified under the securities laws of any
state, the Company at its discretion may impose restrictions upon the sale,
pledge or other transfer of the Purchased Shares (including the placement of
appropriate legends on stock certificates or the imposition of stop-transfer
instructions) if, in the judgment of the Company, such restrictions are
necessary or desirable in order to achieve compliance with the Securities Act,
the securities laws of any state or any other law.

        (c) Market Stand-Off. In connection with any underwritten public
offering by the Company of its equity securities pursuant to an effective
registration statement filed under the Securities Act, including the Company's
initial public offering, the Purchaser shall not directly or indirectly sell,
make any short sale of, loan, hypothecate, pledge, offer, grant or sell any
option or other contract for the purchase of, purchase any option or other
contract for the sale of, or otherwise dispose of or transfer, or agree to
engage in any of the foregoing transactions with respect to, any Purchased
Shares without the prior written consent of the Company or its underwriters.
Such restriction (the "Market Stand-Off") shall be in effect for such period
of time following the date of the final prospectus for the offering as may be
requested by the Company or such underwriters. In no event, however, shall
such period exceed 180 days. The Market Stand-Off shall in any event terminate
two years after the date of the Company's initial public offering. In the
event of the declaration of a stock dividend, a spin-off, a stock split, an
adjustment in conversion ratio, a recapitalization or a similar transaction
affecting the Company's outstanding securities without receipt of
consideration, any new, substituted or additional securities which are by
reason of such transaction distributed with respect to any Shares subject to
the Market Stand-Off, or into which such Shares thereby become convertible,
shall immediately be subject to the Market Stand-Off. In order to enforce the
Market Stand-Off, the Company may impose stop-transfer instructions with
respect to the Purchased Shares until the end of the applicable stand-off
period. The Company's underwriters shall be beneficiaries of the agreement set
forth in this Subsection (c). This Subsection (c) shall not apply to Shares
registered in the public offering under the Securities Act, and the Purchaser
shall be subject to this Subsection (c) only if the directors and officers of
the Company are subject to similar arrangements.

        (d) Rights of the Company. The Company shall not be required to (i)
transfer on its books any Purchased Shares that have been sold or transferred
in contravention of this Agreement or (ii) treat as the owner of Purchased
Shares, or otherwise to accord voting, dividend or liquidation rights to, any
transferee to whom Purchased Shares have been transferred in contravention of
this Agreement.

SECTION 5.   SUCCESSORS AND ASSIGNS.

          Except as otherwise expressly provided to the contrary, the provisions
of this Agreement shall inure to the benefit of, and be binding upon, the
Company and its successors and assigns and be binding upon the Purchaser and the
Purchaser's legal representatives, heirs,

                                      6
<PAGE>

legatees, distributees, assigns and transferees by operation of law, whether
or not any such person has become a party to this Agreement or has agreed in
writing to join herein and to be bound by the terms, conditions and
restrictions hereof.

SECTION 6.   NO RETENTION RIGHTS.

          Nothing in this Agreement or in the Plan shall confer upon the
Purchaser any right to continue in Service for any period of specific duration
or interfere with or otherwise restrict in any way the rights of the Company (or
any Parent or Subsidiary employing or retaining the Purchaser) or of the
Purchaser, which rights are hereby expressly reserved by each, to terminate his
or her Service at any time and for any reason, with or without cause.

SECTION 7.   TAX ELECTION.

          The acquisition of the Purchased Shares may result in adverse tax
consequences that may be avoided or mitigated by filing an election under Code
Section 83(b).  Such election may be filed only within 30 days after the date of
purchase set forth in the Summary of Stock Purchase.  The form for making the
Code Section 83(b) election is attached to this Agreement as an Exhibit.  The
Purchaser should consult with his or her tax advisor to determine the tax
consequences of acquiring the Purchased Shares and the advantages and
disadvantages of filing the Code Section 83(b) election.  The Purchaser
acknowledges that it is his or her sole responsibility, and not the Company's,
to file a timely election under Code Section 83(b), even if the Purchaser
requests the Company or its representatives to make this filing on his or her
behalf.

SECTION 8.   LEGENDS.

          All certificates evidencing Purchased Shares shall bear the following
legends:

     "THE SHARES REPRESENTED HEREBY MAY NOT BE SOLD, ASSIGNED, TRANSFERRED,
     ENCUMBERED OR IN ANY MANNER DISPOSED OF, EXCEPT IN COMPLIANCE WITH THE
     TERMS OF A WRITTEN AGREEMENT BETWEEN THE COMPANY AND THE REGISTERED HOLDER
     OF THE SHARES (OR THE PREDECESSOR IN INTEREST TO THE SHARES).  SUCH
     AGREEMENT GRANTS TO THE COMPANY CERTAIN RIGHTS OF FIRST REFUSAL UPON AN
     ATTEMPTED TRANSFER OF THE SHARES AND CERTAIN REPURCHASE RIGHTS UPON
     TERMINATION OF SERVICE WITH THE COMPANY.  THE SECRETARY OF THE COMPANY WILL
     UPON WRITTEN REQUEST FURNISH A COPY OF SUCH AGREEMENT TO THE HOLDER HEREOF
     WITHOUT CHARGE."

     "THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
     SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, PLEDGED, OR
     OTHERWISE TRANSFERRED WITHOUT AN

                                      7
<PAGE>

     EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT OR AN OPINION OF COUNSEL,
     SATISFACTORY TO THE COMPANY AND ITS COUNSEL, THAT SUCH REGISTRATION IS
     NOT REQUIRED."

If required by the authorities of any state in connection with the issuance of
the Purchased Shares, the legend or legends required by such state authorities
shall also be endorsed on all such certificates.

SECTION 9.   NOTICE.

          Any notice required by the terms of this Agreement shall be given in
writing and shall be deemed effective upon personal delivery or upon deposit
with the United States Postal Service, by registered or certified mail, with
postage and fees prepaid.  Notice shall be addressed to the Company at its
principal executive office and to the Purchaser at the address that he or she
most recently provided to the Company.

SECTION 10.  ENTIRE AGREEMENT.

          The Summary of Stock Purchase, this Agreement and the Plan constitute
the entire contract between the parties hereto with regard to the subject matter
hereof.  They supersede any other agreements, representations or understandings
(whether oral or written and whether express or implied) which relate to the
subject matter hereof.

SECTION 11.  CHOICE OF LAW.

          This Agreement shall be governed by, and construed in accordance with,
the laws of the State of California, as such laws are applied to contracts
entered into and performed in such State.

appointed, such Committee.

        (c)  "Change in Control" shall mean:

             (i)   The consummation of a merger or consolidation of the
     Company with or into another entity or any other corporate
     reorganization, if more than 50% of the combined voting power of the
