COMPLIANCE WITH REGULATION S UNDER THE ACT, IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO THE SECURITIES UNDER THE ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED, OR UNLESS SOLD
PURSUANT TO RULE 144 PROMULGATED UNDER THE ACT. ANY SUCH TRANSFER MAY ALSO BE SUBJECT TO APPLICABLE STATE SECURITIES LAWS. HEDGING TRANSACTIONS INVOLVING THESE SECURITIES MAY NOT BE CONDUCTED UNLESS IN COMPLIANCE WITH THE ACT.” 
 Each Holder consents to the Company making a notation on its records and giving instructions to any transfer agent of the Registrable Securities in order
to implement the restrictions on transfer established in this Agreement. 
  

	6.	Notice of Proposed Transfer. The Holder of each certificate representing Registrable Securities, by acceptance thereof, agrees to comply in all respects with the provisions
of this Section 6. Each such Holder agrees not to make any disposition of all or any portion of any Registrable Securities held by it directly or indirectly unless and until: 

  

	 	6.1.	There is in effect a registration statement under the Securities Act covering such proposed disposition and such disposition is made in accordance with such registration statement;
or

		  	- 9 -	  	










	 	6.2.	(i) Such Holder shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement of the circumstances surrounding the
proposed disposition; and 

 (ii) If reasonably requested by the Company, such Holder shall furnish the Company with an opinion
of counsel, reasonably satisfactory to the Company that such disposition shall not require registration of such shares under the Securities Act. It is agreed, however, that no such opinion will be required for Rule 144 or Rule 144A transactions,
except in unusual circumstances. 
  

	 	6.3.	Notwithstanding the provisions of paragraphs 6.2(i) and (ii) above, no such registration statement or opinion of counsel shall be necessary for a transfer by a Holder to a
party to which such holder may make a transfer or assignment pursuant to Section 11.3 below, provided, that such transferee agrees in writing to be subject to all of the terms hereof to the same extent as if he were an original Holder
hereunder. 

  

	7.	Registration. The following provisions shall govern the registration of the Company’s securities: 

  

	 	7.1.	Incidental (“Piggyback”) Registration. If the Company at any time proposes to register any of its securities, other than in a demand registration pursuant to
Section 7.2(a) or Section 7.3 of this Agreement, it shall give notice to the Holders of such intention. Upon the written request of any Holder given within twenty (20) days after receipt of any such notice, the Company shall take all
actions under its power and control to include in such registration all of the Registrable Securities indicated in such request, so as to permit the disposition of the shares so registered. Notwithstanding any other provision of this Section, if the
managing underwriter advises the Company in writing that marketing factors require a limitation of the number of shares to be underwritten, then there shall be excluded from such registration and underwriting to the extent necessary to satisfy such
limitation, first shares held by shareholders other than the Holders, and then to the extent necessary, shares held by the Holders (pro rata to the respective number of Registrable Securities held by such Holders). The Company shall have the right
to terminate or withdraw any registration initiated by it under this Section 7.1 prior to the effectiveness of such registration whether or not any Holder has elected to include securities in such registration. The registration expenses of such
withdrawn registration shall be borne by the Company in accordance with Section 7.6. 

  


					
	BigBand Networks FIFTH AMENDED AND RESTATED INVESTORS RIGHTS AGREEMENT
			
		  	- 10 -	  	










	 	7.2.	Demand Registration. (a) At any time beginning six (6) months following the closing of an IPO, the Initiating Holders may request in writing that all or part of the
Registrable Securities held by such Holder shall be registered for trading. Within twenty (20) days after receipt of any such request, the Company shall give written notice of such request to the other Holders and shall take all actions under
its power and control to include in such registration all Registrable Securities held by all such Holders who wish to participate in such demand registration and who provide the Company with written requests for inclusion therein within fifteen
(15) days after the receipt of the Company’s notice. Thereupon, the Company shall effect the registration of all Registrable Securities as to which it has received requests for registration with an underwriter acceptable to the holders of
a majority of the participating Registrable Securities. The Company shall not be required to effect more than two (2) registrations under this Section 7.2, nor shall the Company be required to effect a registration for the sale of shares
with an anticipated sales price of less than Five Million Dollars ($5,000,000). Notwithstanding any other provision of this Section 7.2, if the managing underwriter advises the Company in writing that marketing factors require a limitation of
the number of shares to be underwritten, then there shall be excluded from such registration and underwriting to the extent necessary to satisfy such limitation, first shares held by shareholders other than the Holders, and then to the extent
necessary, shares held by the Holders (pro rata to the respective number of Registrable Securities held by such Holders). 

 (b)
In the event that the Initiating Holders request to effect a registration under this Section and the Company decides to join and register any of its securities thereunder, then, such registration shall not be regarded as a Demand Registration under
Section 7.2. 
  

	 	7.3.	 Form S-3 Registration. In case the Company shall receive from any Holder or Holders a written request or requests that the Company effect a registration on
Form S-3, and any related qualification or compliance, with respect to Registrable Securities, the reasonably anticipated aggregate price to the public of which would exceed $1,000,000 (One Million Dollars), the Company will within twenty
(20) days after receipt of any such request give written notice of the proposed registration, and any related qualification or compliance, to all other Holders, and shall take all actions under its power and control to include in such
registration all Registrable Securities held by all such Holders who wish to participate in such registration and who provide the Company with written requests for inclusion therein within fifteen (15) days after the receipt of the
Company’s notice. Thereupon, the Company shall take all actions under its power and 



  


					
	BigBand Networks FIFTH AMENDED AND RESTATED INVESTORS RIGHTS AGREEMENT
			
		  	- 11 -	  	










	 	 
control to effect such registration and all such qualifications and compliances as may be so requested and as would permit or facilitate the sale and
distribution of all or such portion of such Holder’s or Holders’ Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any other Holder or Holders joining in such
request as are specified in a written request given within fifteen (15) days after receipt of such written notice from the Company; provided, however, that the Holders of Registrable Securities may not request more than two
(2) registrations pursuant to this Section 7.3 during any twelve-month period and any such registration pursuant to this Section 7.3 shall not be counted as a demand for registration pursuant to section 7.2.



  

	 	7.4.	Notwithstanding Sections 7.2 and 7.3 above, the Company shall not be required to effect any registration: (i) within one hundred and twenty (120) days after the effective
date of any other registration effected; or (iii) during the pending period of any Demand Blackout Period (as hereinafter defined). 

 “Blackout Periods.” If the Company’s Board of Directors determines in good faith that the registration and distribution of Registrable Securities (or the use of a registration statement or related
prospectus) would interfere with any pending financing, acquisition, corporate reorganization or any other material corporate development involving the Company (or would require premature disclosure thereof), and promptly gives the Holders written
notice of such determination following their request to register any Registrable Securities, the Company shall be entitled to postpone the filing of the registration statement otherwise required to be prepared and filed by the Company pursuant to
Sections 7.2 or 7.3 for a reasonable period of time, but not to exceed 90 days (a “Demand Blackout Period”). The Company shall promptly notify the Holders of the expiration or earlier termination of any Demand Blackout Period. 

In any event of a Demand Blackout Period, the Company undertakes to extend the effectiveness of the then current registration statement beyond the
anticipated nine months period for the respective periods of such Demand Blackout Period. 
  

	 	7.5.	Designation of Underwriter. (a) In the case of any registration effected pursuant to Section 7.2 or 7.3 and in the event the Initiating Holders intend to distribute
the Registrable Securities by means of an underwriting, a majority of the Initiating Holders that submitted requests for registration shall have the right to designate the managing underwriter(s) in any underwritten offering who shall be a prominent
and reputable underwriter, subject to the consent of the Company, which consent shall not be unreasonably withheld. 

  


					
	BigBand Networks FIFTH AMENDED AND RESTATED INVESTORS RIGHTS AGREEMENT
			
		  	- 12 -	  	









 (b) In the case of any registration initiated by the Company, the Company shall have the right to
designate the managing underwriter in any underwritten offering. 
 (c) The right of any Holder to include its Registrable Securities in such
registration shall be conditioned upon such Holder’s participation in such underwriting and entering into an underwriting agreement in customary form with the underwriter or underwriters. 
  

	 	7.6.	Expenses. All expenses incurred in connection with any registration under Section 7.1, Section 7.2 or Section 7.3, including the reasonable fees and expenses
of one counsel for the selling shareholders (including the Holders), shall be borne by the Company; provided, however, that each of the Holders participating in such registration shall pay its pro rata portion of the fees, discounts or
commissions payable to any underwriter, 

  

	 	7.7.	Indemnities. In the event of any registered offering of Common Stock pursuant to this Section 7: 

  

	 	7.7.1.	 The Company will indemnify and hold harmless, to the fullest extent permitted by law, any Holder and any underwriter for such Holder, the partners, officers and
directors of each Holder and each person, if any, who controls the Holder or such underwriter, from and against any and all losses, damages, claims, liabilities, joint or several, costs and expenses (including any amounts paid in any settlement
effected with the Company’s consent) to which the Holder or any such underwriter or controlling person may become subject under applicable law or otherwise, insofar as such losses, damages, claims, liabilities (or actions or proceedings in
respect thereof), costs or expenses arise out of or are based upon (i) any untrue statement or alleged 11 untrue statement of any material fact contained in the registration statement or included in the prospectus, as amended or supplemented,
(ii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances in which they are made, not misleading, or (iii) any
violation or alleged violation by the Company of the Securities Act, the Exchange Act or any rule or regulation promulgated under the 



  


					
	BigBand Networks FIFTH AMENDED AND RESTATED INVESTORS RIGHTS AGREEMENT
			
		  	- 13 -	  	










	 	 
Securities Act, the Exchange Act or any state securities law in connection with the offering covered by such registration statement and the Company will
reimburse the Holder, the partners, officers and directors of each Holder, such underwriter and each such controlling person of the Holder or the underwriter, promptly upon demand, for any reasonable legal or any other expenses incurred by them in
connection with investigating, preparing to defend or defending against or appearing as a third-party witness in connection with such loss, claim, damage, liability, action or proceeding; provided, however, that the Company will not be
liable in any such case to the extent that any such loss, damage, liability, cost or expense arises out of or is based upon an untrue statement or alleged untrue statement or omission so made in conformity with information furnished in writing by a
Holder, such underwriter or such controlling persons in writing specifically for inclusion therein; provided, further, that this indemnity shall not be deemed to relieve any underwriter of any of its due diligence obligations;
provided, further, that the indemnity agreement contained in this subsection 7.7.1 shall not apply to amounts paid in settlement of any such claim, loss, damage, liability or action if such settlement is effected without the consent of
the Company, which consent shall not be unreasonably withheld. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the selling shareholder, the underwriter or any controlling person of the
selling shareholder or the underwriter, and regardless of any sale in connection with such offering by the selling shareholder. Such indemnity shall survive the transfer of securities by a selling shareholder. 


  

	 	7.7.2.	 Each Holder participating in a registration hereunder will indemnify and hold harmless the Company, any underwriter for the Company, and each person, if any, who
controls the Company or such underwriter, from and against any and all losses, damages, claims, liabilities, costs or expenses (including any amounts paid in any settlement effected with the selling shareholder’s consent) to which the Company
or any such controlling person and/or any such underwriter may become subject under applicable law or otherwise, insofar as such losses, damages, claims, liabilities (or actions or proceedings in respect thereof), costs or expenses arise out of or
are based on (i) any untrue statement or alleged untrue statement of any material fact 



  


					
	BigBand Networks FIFTH AMENDED AND RESTATED INVESTORS RIGHTS AGREEMENT
			
		  	- 14 -	  	










	 	 
contained in the registration statement or included in the prospectus, as amended or supplemented, or (ii) the omission to state therein a material fact
required to be stated therein or necessary to make the statements therein, in the light of the circumstances in which they were made, not misleading, and each such Holder will reimburse the Company, any underwriter and each such controlling person
of the Company or any underwriter, promptly upon demand, for any reasonable legal or other expenses incurred by them in connection with investigating, preparing to defend or defending against or appearing as a third-party witness in connection with
such loss, claim, damage, liability, action or proceeding; in each case to the extent,, but only to the extent, that such untrue statement or omission was so made in strict conformity with written information furnished by such Holder specifically
for inclusion therein. The foregoing indemnity agreement is subject to the condition that, insofar as it relates to any such untrue statement or alleged untrue statement or omission made in the preliminary prospectus but eliminated or remedied in
the amended prospectus at the time the registration statement becomes effective or in the final prospectus, such indemnity agreement shall not inure to the benefit of (i) the Company and (ii) any underwriter, if a copy of the final
prospectus was not furnished to the person or entity asserting the loss, liability, claim or damage at or prior to the time such furnishing is required by the Securities Act; provided, further, that this indemnity shall not be deemed
to relieve any underwriter of any of its due diligence obligations; provided, further, that the indemnity agreement contained in this subsection 7.7.2 shall not apply to amounts paid in settlement of any such claim, loss, damage,
liability or action if such settlement is effected without the consent of the Holders, as the case may be, which consent shall not be unreasonably withheld. In no event shall the liability of a Holder exceed the net proceeds received by such Holder
from the sale of its securities under the applicable registration. 


  

	 	7.7.3.	 Promptly after receipt by an indemnified party pursuant to the provisions of Sections 7.7.1 or 7.7.2 of notice of the commencement of any action involving the
subject matter of the foregoing indemnity provisions, such indemnified party will, if a claim thereof is to be made against the indemnifying party pursuant to the provisions of said Sections 7.7.1 or 7.7.2, promptly notify the indemnifying party of
the commencement 



  


					
	BigBand Networks FIFTH AMENDED AND RESTATED INVESTORS RIGHTS AGREEMENT
			
		  	- 15 -	  	










	 	 
thereof; but the omission to notify the indemnifying party, if not actually prejudicial, will not relieve the indemnifying party from any liability which it
may have to any indemnified party. In case such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party shall have the right to participate in, and, to the extent
that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof with counsel mutually satisfactory to each party; provided, however, that if the defendants in any action include both the
indemnified party and the indemnifying party and there is a conflict of interests which would prevent counsel for the indemnifying party from also representing the indemnified party, the indemnified party or parties shall have the right to select
one separate counsel to participate in the defense of such action on behalf of such indemnified party or parties. After notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying
party will not be liable to such indemnified party pursuant to the provisions of said Sections 7.7.1 or 7.7.2 for any legal or other expense subsequently incurred by such indemnified party in connection with the defense thereof, unless (i) the
indemnified party shall have employed counsel in accordance with the provision of the preceding sentence, (ii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified
party within a reasonable time after the notice of the commencement of the action and within fifteen (15) days after written notice of the indemnified party’s intention to employ separate counsel pursuant to the previous sentence, or (III)
the indemnifying party has authorized the employment of counsel for the indemnified party at the expense of the indemnifying party. No indemnifying party will consent to entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation. 


  

	 	7.7.4.	 If recovery is not available under the foregoing indemnification provisions, for any reason other than as specified therein, the parties entitled to indemnification
by the terms thereof shall be entitled to contribution to liabilities and expenses as more fully set forth in an underwriting agreement to be executed in connection with such registration, if any. In any event, in 



  


					
	BigBand Networks FIFTH AMENDED AND RESTATED INVESTORS RIGHTS AGREEMENT
			
		  	- 16 -	  	










	 	 
determining the amount of contribution to which the respective parties are entitled, there shall be considered the parties’ relative knowledge and
access to information concerning the matter with respect to which the claim was asserted, the opportunity to correct and prevent any statement or omission, and any other equitable considerations appropriate under the circumstances, provided,
however, that in any such case, no person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person or entity who was not guilty of such
fraudulent misrepresentation. 


  

	 	7.7.5.	If the indemnification provided in this Section 7 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any losses, claims,
damages or liabilities referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party thereunder, shall to the extent permitted by applicable law contribute to the amount paid or payable by such indemnified party as a
result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with this Section 7 that
resulted in the loss, claim, damage or liability, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by a court of law by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent,
knowledge, access to information and opportunity to correct or prevent such statement or omission; provided that in no event shall any contribution by a Holder hereunder exceed the net proceeds from the offering received by such Holder.


 The obligations of the Company and Holders under this Section 7 shall survive completion of any offering of Registrable
Securities in a registration statement and the termination of this Agreement.

	 	7.8.5.	in the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing underwriter
of such offering. Each Holder participating in such underwriting shall also enter into and perform its obligations under such an agreement; 

  

	 	7.8.6.	notify each holder of Registrable Securities covered by such registration statement at any time when a prospectus relating thereto is required to be delivered under the Securities
Act of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or
necessary to make the statements therein not misleading in the light of the circumstances then existing;

statement with respect to such securities becomes effective, (i) an opinion, dated such date, of the counsel representing the Company for the purposes of such registration, in form and substance as is customarily given to underwriters in an
underwritten public offering, addressed to the underwriters, if any, and to the Holders requesting registration of Registrable Securities and (ii) a letter dated as of such date, from the independent certified public accountants of the Company,
in form and substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering, addressed to the underwriters, if any, and to the Holders requesting registration of Registrable
Securities; 

  

	 	7.8.10.	 use reasonable best efforts to obtain the withdrawal of any order suspending the effectiveness of a registration statement, or the lifting of any suspension of the
qualification of any of the Registrable Securities for sale in any jurisdiction, at the earliest possible moment; 

  

	 	7.8.11.	 register or qualify such Registrable Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions as any Holder or underwriter reasonably
requires, and keep such registration or qualification effective during the period set forth in Section 7.8.2 above; 

  


					
	BigBand Networks FIFTH AMENDED AND RESTATED INVESTORS RIGHTS AGREEMENT
			
		  	- 19 -	  	










	 	7.8.12.	 cause its accountants to issue to the underwriter, if any, or the Holders, if there is no underwriter, comfort letters and updates thereof, in customary form and covering
matters of the type customarily covered in such letters with respect to underwritten offerings;

accountants to supply all information reasonably requested by any such seller, underwriter, attorney, accountant or agent in connection with such registration statement; 

  

	 	7.8.14.	 notify each Holder, at any time a prospectus covered by such registration statement is required to be delivered under the Securities Act, of the happening of any event of
which it has knowledge as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to
make the statements therein not misleading in the light of the circumstances then existing and use reasonable efforts to amend or supplement such prospectus in order to cause such prospectus not to include any untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; and 

  

	 	7.8.15.	 take such other actions as shall be reasonably requested by any Holder. 

  

	 	7.9.	 Lock-Up. In any registration of the Company’s shares all Holders and the Founder Shareholders agree that any sales of Registrable Securities or Common

“lock-up” period of up to one hundred eighty (180) days as is required by the underwriter in such registration, provided that such obligation shall only apply where the officers and directors of the 



  


					
	BigBand Networks FIFTH AMENDED AND RESTATED INVESTORS RIGHTS AGREEMENT
			
		  	- 20 -	  	










	 	 
Company, the Founder Shareholders and all other 2% or greater stockholders are subject to a similar lock-up restriction. The Company may impose stop-transfer
instructions with respect to the shares of Common Stock (or other securities) subject to the foregoing restriction until the end of said one hundred eighty (180) day period. Each Holder agrees that transferees of any shares of Registrable
Securities shall be bound by this Section 7.9. 


  

	 	7.10.	Public Information. At any time and from time to time after the earlier of the close of business on such date as (a) a registration statement filed by the Company under
the Securities Act becomes effective, (b) the Company registers a class of securities under Section 12 of the Exchange Act, or (c) the Company issues an offering circular meeting the requirements of Regulation A under the Securities
Act, the Company shall undertake to make publicly available and available to the Investor pursuant to Rule 144, such information as is necessary to enable the Investor to make sales of Registrable Stock pursuant to that Rule. The Company shall
comply with the current public information requirements of Rule 144 and shall furnish thereafter to any Investor, upon request, a written statement executed by the Company as to the steps it has taken to so comply, 

  

	 	7.11.	Foreign Offerings. The provisions of this Section 7 shall apply, mutatis mutandis, to any registration of the securities of the Company outside of the United States.


  

	 	7.12.	Rule 144 and 144A Reporting. With a view to making available to Holders of Registrable Securities the benefits of certain rules and regulations of the SEC which may permit
the sale of the Registrable Securities to the public without registration, the Company agrees at all times after ninety (90) days after the effective date of the first registration filed by the Company for an offering of its securities to the
general public to: 

 (a) make and keep public information available, as those terms are understood and defined in Rule 144 and
Rule 144A or any other similar or analogous rules promulgated under the Securities Act; 
 (b) use its best efforts to file with the
Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act. 
  


					
	BigBand Networks FIFTH AMENDED AND RESTATED INVESTORS RIGHTS AGREEMENT
			
		  	- 21 -	  	









 For purposes of facilitating sales pursuant to Rule 144A, so long as the Company is not subject to the
reporting requirements of Section 13 or 15(d) of the Exchange Act, each Holder and any transferee of such Holder’s securities shall have the right to obtain from the Company, upon request of the Holder prior to the time of sale, a brief
statement of the nature of the business of the Company and the products and services it offers; and the Company’s most recent balance sheet and profit and loss and retained earnings statements, and similar financial statements for the two
preceding fiscal years (the financial statements should be audited to the extent reasonably available). 
  

	 	7.13.	Registration Requirements. If the Company is subject to the reporting requirements of Section 13 or 15 of the Exchange Act as a result of the registration of shares of
its Common Stock under the Exchange Act, any registration pursuant to this Section must be firmly underwritten if the registration exceeds two percent (2%) of the Company’s outstanding Common Stock on an as-converted basis.


  

	 	7.14.	Limitations on Subsequent Registration Rights. From and after the date these registration rights are granted, the Company shall not, without the prior written consent of the
Holders of at least two thirds of the Registrable Securities then held by Holders, enter into any agreement with any holder or prospective holder of any securities of the Company which would allow such Holder or prospective holder to include such
securities in any registration filed under this Section other than rights identical with or subordinate to the rights of any Holder hereunder. 

  

	 	7.15.	Termination of Registration Rights. The registration rights set forth in this Section 7 shall terminate five (5) years after the close of an IPO.


  

	 	7.16.	Delay of Registration: Furnishing Information 

 (a)
No Holder shall have any right to obtain or seek an injunction restraining or otherwise delaying any such registration as a result of any controversy that might arise with respect to interpretation or implementation of this Section 7.

 (b) It shall be a condition precedent to the obligations of the Company to take any action pursuant to Sections 7.1, 7.2 and 7.3 that the
selling Holders shall furnish to the Company such information regarding themselves, the Registrable Securities held by them and the intended method of disposition of such securities as shall be required to effect the registration of their
Registrable Securities.

	8.	Right of Refusal on Company Issuances. Prior to an IPO, (a) Founder Shareholders and (b) the Investors whose equity holdings in the Company constitute at least one
million (1,000,000) shares of the issued and outstanding stock of the Company on an as-converted basis (each of (a) and (b), a “Holder of First Refusal Rights”) will have the right to purchase a pro rata portion of any further
issuance of New Securities (as hereinafter defined) by the Company at the offering price. Each Holder of First Refusal Rights shall also be entitled to purchase the pro rata portion of any Holder of First Refusal Rights that does not exercise such
right. 

  

	 	8.1.	Subject to the foregoing provision, each Holder of First Refusal Rights has rights of first refusal to purchase for its own account and not for resale, pro-rata, all (or any part)
of New Securities that the Company may, from time to time, propose to sell and issue. The Holder of First Refusal Rights’ pro rata share shall be the ratio of the number of shares of the Company’s stock then held by the Holder of First
Refusal Rights (on an as-converted basis) as of the date of the Rights Notice (as defined below), to the sum of the total number of shares of Common Stock then outstanding (including shares issued or issuable upon conversion of the Preferred Stock
or upon the exercise of any outstanding warrants or options then outstanding) as of such date. 

  

	 	8.1.1.	 “New Securities” shall mean any Common Stock or Preferred Stock of any kind of the Company, whether now or hereafter authorized, and rights, options, or
warrants to purchase said Common Stock or Preferred Stock, and securities of any type whatsoever that are, or may become, convertible into said Common Stock or Preferred Stock; provided, however, that “New Securities” shall
not include (i) securities issuable upon conversion of Preferred Stock or exercise of warrants or options already in existence as of the date first written above; (ii) securities issued solely as consideration for the acquisition (whether
by merger or otherwise) by the Company or any of its subsidiaries of all or substantially all of the stock or assets of any other entity (including all or substantially all of the assets of a line of business or division of such entity and
including, without limitation, shares of Common Stock and Preferred Stock issued in connection with the Acquisition Agreement (including, but not limited to shares issued in consideration of indemnity claims)); (iii) securities offered to the
public in an IPO; or (iv) securities issued pursuant to the grant of Common Stock purchase rights (including options, warrants, stock grants or similar rights) to (I) directors, officers, employees or consultants of the Company in
connection with their service to the Company, or (II) service providers of the Company, in each case pursuant to stock purchase or stock option plans or other 



  


					
	BigBand Networks FIFTH AMENDED AND RESTATED INVESTORS RIGHTS AGREEMENT
			
		  	- 23 -	  	










	 	 
arrangements that are approved by the Board (including any options, warrants or restricted stock granted pursuant to Section 2.3.6 of the Series C
Convertible Preferred Stock Purchase Agreement dated as of September 28, 2001 by and among the Company and the Purchasers listed on Exhibit A thereto, as amended from time to time); (v) securities issuable pursuant to any debt or lease
financing transaction and which are approved in advance by the majority of the Board, such majority to include the affirmative vote of at least two (2) of the directors appointed solely by the holders of the Preferred Stock; (vi) shares of
Common Stock issued in connection with any stock split, stock dividend or recapitalization by the Company; (vii) shares of Series E-l Preferred Stock issued pursuant to the Stock Purchase Agreement; (viii) securities issuable in connection
with strategic transactions involving the Company and other entities, including, but not limited to, joint ventures, marketing or distribution arrangements, technology transfer arrangements or development arrangements, and which are approved in

issuable to ADC in connection with a credit facility entered into in connection with the Acquisition Agreement. 


  

	 	8.1.2.	 If the Company proposes to issue New Securities, it shall give the Holders of First Refusal Rights written notice (the “Rights Notice”) of its intention,
describing the New Securities, the price, the general terms upon which the Company proposes to issue them, and the number of shares that the Holder of First Refusal Rights has the right to purchase under this Agreement. Each Holder of First Refusal
Rights shall have fifteen (15) days from delivery of the Rights Notice to agree to purchase all or any part of its pro-rata share of such New Securities and shall have five (5) days from receipt of written notice from the Company that a
Holder of First Refusal Rights has not elected to purchase its pro rata share of the New Securities to purchase all or any part of the pro-rata share of any other Holder of First Refusal Rights (including for this purpose any permitted
transferee of the Holder of First Refusal Rights) entitled to such rights to the extent that such other Holder of First Refusal Rights does not elect to purchase its full pro-rata share, in each case for the price and upon the general terms
specified in the Rights 



  


					
	BigBand Networks FIFTH AMENDED AND RESTATED INVESTORS RIGHTS AGREEMENT
			
		  	- 24 -	  	










	 	 
Notice, by giving written notice to the Company setting forth the quantity of New Securities to be purchased. If Holders of First Refusal Rights who elect to
purchase their full pro-rata shares also elect to purchase in the aggregate more than 100% of the New Securities, such New Securities shall be sold to such Holders of First Refusal Rights in accordance with their respective pro-rata shares.
Notwithstanding the foregoing, the Company shall not be required to offer to sell such New Securities to any Holder of First Refusal Rights who would cause the Company to be in violation of applicable federal securities laws by virtue of such offer
or sale. 


  

	 	8.1.3.	To the extent that the Holders of First Refusal Rights fail to exercise in full the right of first refusal within the period or periods specified above, the Company shall have
ninety (90) days after delivery of the Rights Notice to sell the New Securities to the Holders to the extent that each of them exercised their First Refusal Right at least in part and to other third parties at a price and upon general terms no
more favorable to the purchasers thereof than specified in the Company’s notice, provided that the obligation of any Holder to purchase New Securities shall be contingent on the Company selling all of the New Securities specified in the Rights
Notice at the same time. If the Company has not sold the New Securities within said ninety (90) day period, the Company shall not thereafter issue or sell any New Securities without first offering such securities to the Holders of First Refusal
Rights in the manner provided above. 

  

	 	8.1.4.	The Investors and the Founder Stockholders hereby waive notice of and any right to participate in the sale of the Series E Preferred Stock contemplated by the Stock Purchase
Agreement, and the issuance of any shares of Common Stock issuable upon conversion of any such shares of Series E Preferred Stock. 

  

	 	8.2.	 The rights of first refusal established by this Section 8 shall not apply to, and shall terminate upon the earlier of (i) the effective date of the
registration statement pertaining to the Company’s IPO or (ii) an acquisition of the Company by another corporation or entity by consolidation, merger or other reorganization in which the holders of the Company’s outstanding voting
stock immediately prior to such transaction own, immediately after such transaction, securities representing less than

fifty percent (50%) of the voting power of the corporation or other entity surviving such transaction.
