EXHIBIT A

TERMS AND CONDITIONS OF STOCK OPTION GRANT

1. Grant. The Company hereby grants to the Participant named in the Notice of
Grant (the “Participant”) an option (the “Option”) to purchase the number of
Shares, as set forth in the Notice of Grant, at the exercise price per Share set
forth in the Notice of Grant (the “Exercise Price”), subject to all of the terms
and conditions in this Agreement, the Plan and the Sub-Plan, which are
incorporated herein by reference. Subject to Section 18(c) of the Plan, in the
event of a conflict between the terms and conditions of the Plan and the terms
and conditions of this Agreement, the terms and conditions of the Plan will
prevail.

2. Vesting Schedule. Except as provided in Section 3, the Option awarded by this
Agreement will vest in accordance with the vesting provisions set forth in the
Notice of Grant. Shares scheduled to vest on a certain date or upon the
occurrence of a certain condition will not vest in Participant in accordance
with any of the provisions of this Agreement, unless Participant will have been
continuously a Service Provider from the Date of Grant until the date such
vesting occurs.

3. Administrator Discretion. The Administrator, in its discretion, may
accelerate the vesting of the balance, or some lesser portion of the balance, of
the unvested Option at any time, subject to the terms of the Plan and the
Sub-Plan. If so accelerated, such Option will be considered as having vested as
of the date specified by the Administrator.

4. Exercise of Option. This Option may be exercised only within the term set out
in the Notice of Grant, and may be exercised during such term only in accordance
with the Plan, the Sub-Plan and the terms of this Agreement.

This Option is exercisable by delivery of an exercise notice, in the form
attached as Exhibit B (the “Exercise Notice”) or in a manner and pursuant to
such procedures as the Administrator may determine, which will state the
election to exercise the Option, the number of Shares in respect of which the
Option is being exercised (the “Exercised Shares”), and such other
representations and agreements as may be required by the Company pursuant to the
provisions of the Plan. The Exercise Notice will be completed by Participant and
delivered to the Company. The Exercise Notice will be accompanied by payment of
the aggregate Exercise Price as to all Exercised Shares together with any
applicable tax withholding. This Option will be deemed to be exercised upon
receipt by the Company of such fully executed Exercise Notice accompanied by
such aggregate Exercise Price.

5. Method of Payment. Payment of the aggregate Exercise Price will be by any of
the following, or a combination thereof, at the election of Participant:

(a) cash;

(b) check;

(c) consideration received by the Company under a formal cashless exercise
program adopted by the Company in connection with the Plan; or

 

-3-

--------------------------------------------------------------------------------

(d) surrender of other Shares, provided Shares acquired directly or indirectly
from the Company, (A) have been owned by the Participant and not subject to a
substantial risk of forfeiture for more than six (6) months on the date of
surrender, and (B) have a Fair Market Value on the date of surrender equal to
the aggregate Exercise Price of the Exercised Shares.

6. Tax Obligations.

(a) Israeli Taxes. If designated in the Notice of Grant as Section 102(b)(2)
Options, the Options are intended to qualify as options for the capital track
special tax treatment within the meaning of Section 102 of the Israeli Tax
Ordinance (New Version), 5721-1961, as amended (the “Ordinance”), and the Income
Tax Rules (Tax Benefits in Share Issuances to Employees) 5763-2003 (the
“Rules”).

(b) Withholding of Taxes. Notwithstanding any contrary provision of this
Agreement, no certificate representing the Shares will be issued to Participant,
unless and until satisfactory arrangements (as determined by the Administrator)
will have been made by Participant with respect to the payment of income,
employment and other taxes which the Company determines must be withheld with
respect to such Shares. To the extent determined appropriate by the Company in
its discretion, it shall have the right (but not the obligation) to satisfy any
tax withholding obligations by reducing the number of Shares otherwise
deliverable to Participant. If Participant fails to make satisfactory
arrangements for the payment of any required tax withholding obligations
hereunder at the time of the Option exercise, Participant acknowledges and
agrees that the Company may refuse to honor the exercise and refuse to deliver
Shares if such withholding amounts are not delivered at the time of exercise.

7. Rights as Stockholder. Neither Participant nor any person claiming under or
through Participant will have any of the rights or privileges of a stockholder
of the Company in respect of any Shares deliverable hereunder unless and until
certificates representing such Shares will have been issued, recorded on the
records of the Company or its transfer agents or registrars, and delivered to
Participant. After such issuance, recordation and delivery, Participant will
have all the rights of a stockholder of the Company with respect to voting such
Shares and receipt of dividends and distributions on such Shares.

8. No Guarantee of Continued Service. PARTICIPANT ACKNOWLEDGES AND AGREES THAT
THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY
CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (OR THE PARENT OR
SUBSIDIARY EMPLOYING OR RETAINING PARTICIPANT) AND NOT THROUGH THE ACT OF BEING
HIRED, BEING GRANTED THE OPTION OR ACQUIRING SHARES HEREUNDER. PARTICIPANT
FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS
CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT
CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE
PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND WILL NOT
INTERFERE IN ANY WAY WITH PARTICIPANT’S RIGHT OR THE RIGHT OF THE COMPANY (OR
THE PARENT OR SUBSIDIARY EMPLOYING OR RETAINING

this Agreement will be addressed to the Company at BigBand Networks, Inc.,
[ADDRESS], or at such other address as the Company may hereafter designate in
writing.

10. Grant is Not Transferable. This Option may not be transferred in any manner
otherwise than by will or by the laws of descent or distribution and may be
exercised during the lifetime of Participant only by Participant.

11. Binding Agreement. Subject to the limitation on the transferability of this
grant contained herein, this Agreement will be binding upon and inure to the
benefit of the heirs, legatees, legal representatives, successors and assigns of
the parties hereto.

12. Additional Conditions to Issuance of Stock. If at any time the Company will
determine, in its discretion, that the listing, registration or qualification of
the Shares upon any securities exchange or under any state or federal law, or
the consent or approval of any governmental regulatory authority is necessary or
desirable as a condition to the issuance of Shares to Participant (or his or her
estate), such issuance will not occur unless and until such listing,
registration, qualification, consent or approval will have been effected or
obtained free of any conditions not acceptable to the Company. The Company will
make all reasonable efforts to meet the requirements of any such state or
federal law or securities exchange and to obtain any such consent or approval of
any such governmental authority. Assuming such compliance, for income tax
purposes the Exercised Shares will be considered transferred to Participant on
the date the Option is exercised with respect to such Exercised Shares.

13. Plan Governs. This Agreement is subject to all terms and provisions of the
Plan and the Sub-Plan. In the event of a conflict between one or more provisions
of this Agreement and one or more provisions of the Plan or the Sub-Plan, the
provisions of the Plan and the Sub-Plan will govern. Capitalized terms used and
not defined in this Agreement will have the meaning set forth in the Plan or the
Sub-Plan.

14. Administrator Authority. The Administrator will have the power to interpret
the Plan, the Sub-Plan and this Agreement, and to adopt such rules for the
administration, interpretation and application of the Plan and the Sub-Plan as
are consistent therewith and to interpret or revoke any such rules (including,
but not limited to, the determination of whether or not any Shares subject to
the Option have vested). All actions taken and all interpretations and
determinations made by the Administrator in good faith will be final and binding
upon Participant, the Company and all other interested persons. No member of the
Administrator will be personally liable for any action, determination or
interpretation made in good faith with respect to the Plan, the Sub-Plan or this
Agreement.

designated by the Company.

16. Captions. Captions provided herein are for convenience only and are not to
serve as a basis for interpretation or construction of this Agreement.

17. Agreement Severable. In the event that any provision in this Agreement will
be held invalid or unenforceable, such provision will be severable from, and
such invalidity or unenforceability will not be construed to have any effect on,
the remaining provisions of this Agreement.

18. Modifications to the Agreement. This Agreement constitutes the entire
understanding of the parties on the subjects covered. Participant expressly
warrants that he or she is not accepting this Agreement in reliance on any
promises, representations, or inducements other than those contained herein.
Modifications to this Agreement, the Plan or the Sub-Plan can be made only in an
express written contract executed by a duly authorized officer of the Company.
