 FORM OF REVERSE OF DEBENTURE 
 MENTOR GRAPHICS CORPORATION 
 FLOATING RATE CONVERTIBLE SUBORDINATED DEBENTURE
DUE 2023 
  
 This Debenture is one of a duly authorized issue
of Debentures of the Company, designated as its Floating Rate Convertible Subordinated Debentures due 2023 (herein called the “Debentures”), limited to the aggregate principal amount of $100,000,000 (or $110,000,000 if the
option set forth in Section 2 of the Purchase Agreement dated as of July 31, 2003 (as amended from time to time by the parties thereto) by and between the Company and the Initial Purchasers is exercised in full) all issued or to be issued under and
pursuant to an Indenture dated as of August 6, 2003 (herein called the “Indenture”), between the Company and Wilmington Trust Company, as trustee (herein called the “Trustee”), to which Indenture and all indentures
supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the holders of the Debentures. 
  
 In case an Event of Default (as defined in the Indenture) shall have occurred
and be continuing, the principal of, premium, if any, and accrued interest (including Liquidated Damages (as defined in the Registration Rights Agreement), if any) on all Debentures may be declared due and payable, in the manner, with the effect and
subject to the conditions provided in the Indenture. 
  
 The
Indenture contains provisions permitting the Company and the Trustee, with the consent of the holders of not less than a majority in aggregate principal amount of the Debentures at the time outstanding, to execute supplemental indentures adding any
provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying in any manner the rights of the holders of the Debentures. Notwithstanding the foregoing, the written consent
of each Debentureholders affected, an amendment, supplement or waiver, including a waiver pursuant to Section 7.07 of the Indenture, may not: (i) change the fixed maturity of any Debenture; (ii) reduce the rate or change the time of payment of
interest or Liquidated Damages on any Debenture; (iii) reduce the principal amount of any Debenture or premium, if any, thereon, or reduce any amount payable on redemption or repurchase thereof or reduce the amount of Liquidated Damages payable
thereon; (iv) impair the right of any Debentureholders to institute suit for the enforcement of any payment on a Debenture or with respect to the conversion of a Debenture; (v) make the principal of any Debenture or interest or premium, if any, or
Liquidated Damages on any Debenture payable in any coin or currency other than that provided in the Debentures; (vi) modify the provisions of this Indenture with respect to the redemption of the Debentures in a manner adverse to the Debentureholders
in any material respect; (vii) except as contemplated by Article 12 of the Indenture, change the obligation of the Company to repurchase any Debenture upon the happening of a Change of Control in a manner adverse to the Debentureholders; (viii)
impair or adversely affect the right to convert the Debentures into Common Stock subject to the terms set forth herein without the consent of each Debentureholder so affected; (ix) alter the manner of calculation or rate of accrual of Liquidated
Damages on any Debenture or extend the time for payment of such amount; or (x) reduce the percentage of Debentures, the holders of which are required to consent to any modification, amendment or supplemental indenture or the percentage of
Debentures, or the holders of which are required for any other waiver under the Indenture. 

 
Subject to the provisions of the Indenture, the holders of a majority in aggregate principal amount of the Debentures at the time outstanding may on behalf
of the holders of all of the Debentures waive any past default or Event of Default under the Indenture and its consequences except a default in the payment of interest (including Liquidated Damages, if any) or any premium, if any, on, or the
principal of, the Debentures, or a failure by the Company to convert any Debentures into Common Stock of the Company, or a default in the payment of the redemption price pursuant to Article 3 of the Indenture, or a default in respect of a covenant
or provisions of the Indenture which under Article 11 of the Indenture cannot be modified without the consent of the holders of each or all Debentures then outstanding or affected thereby. Any such consent or waiver by the holder of this Debenture
(unless revoked as provided in the Indenture) shall be conclusive and binding upon such holder and upon all future holders and owners of this Debenture and any Debentures which may be issued in exchange or substitution hereof, irrespective of
whether or not any notation thereof is made upon this Debenture or such other Debentures. 
  
 The indebtedness evidenced by the Debentures is, to the extent and in the manner provided in the Indenture, expressly subordinated and subject in right of payment to the prior payment in full of all Senior Debt of the
Company, whether outstanding at the date of the Indenture or thereafter incurred, and this Debenture is issued subject to the provisions of the Indenture with respect to such subordination. Each holder of this Debenture, by accepting the same,
agrees to and shall be bound by such provisions and authorizes the Trustee on its behalf to take such action as may be necessary or appropriate to effectuate the subordination so provided and appoints the Trustee his attorney-in-fact for such
purpose. 
  
 No reference herein to the Indenture and no provision
of this Debenture or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest (including Liquidated Damages, if any) on this Debenture at the
place, at the respective times, at the rate and in the coin or currency herein prescribed. 
  
 Interest on the Debentures shall be computed using the actual number of days elapsed between the Reset Dates divided by 360. 
  
 The Debentures are issuable in fully registered form, without coupons, in denominations of $1,000 principal amount and any integral multiple of $1,000. At
the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, without payment of any service charge but with payment of a sum sufficient to cover any tax, assessment
or other governmental charge that may be imposed in connection with any registration or exchange of Debentures, Debentures may be exchanged for a like aggregate principal amount of Debentures of any other authorized denominations. 
  
 The Debentures will not be redeemable at the option of the Company prior to
August 6, 2007. At any time on or after August 6, 2007, and prior to maturity, the Debentures may be redeemed at the option of the Company, in whole or in part, upon mailing a notice of such redemption not less than 20 days but not more than 60 days
before the date fixed for redemption to the holders of Debentures at their last registered addresses, all as provided in the 

 
Indenture, at the following optional redemption prices (expressed as percentages of the principal amount), together in each case with accrued and unpaid
interest (including Liquidated Damages (as defined in the Indenture), if any) to, but excluding, the date fixed for redemption: 
  

	 Period

	  	Redemption Price

	 
	 Beginning on August 6, 2007 and ending on August 5, 2008
	  	102.42	%
	 Beginning on August 6, 2008 and ending on August 5, 2009
	  	101.61	%
	 Beginning on August 6, 2009 and ending on August 5, 2010
	  	100.81	%

  
 and 100% on August 6, 2010 and at any
time thereafter; provided, however, that, with the sole of exception of August 6, 2007, if the date fixed for redemption is on a February 6, May 6, August 6 or November 6, then the interest payable on such date shall be paid to the holder of
record on the preceding January 21, April 21, July 21 or October 21, respectively. Debentures or portions of Debentures called for redemption will be convertible until the close of business on the Business Day prior to the date fixed for redemption.

  
 The Company may not give notice of any redemption of the
Debentures if a default in the payment of interest or premium, if any, on the Debentures has occurred and is continuing. 
  
 The Debentures are not subject to redemption through the operation of any sinking fund. 
  
 On August 6, 2010, August 6, 2013 and August 6, 2018, the holders of the Debentures shall have the right to require the
Company to repurchase at such holder’s option all of such holders’ Debentures, or any portion thereof that is an integral multiple of $1,000 principal amount, on the Purchase Date (as defined in the Indenture) in cash at a price equal to
100% of the principal amount thereof, together with accrued interest (including Liquidated Damages, if any) to, but excluding the Purchase Date. The Company shall mail to all holders of record of the Debentures a notice of an upcoming Purchase Date
not less than 20 Business Days prior to the Purchase Date. For a Debenture to be so repurchased at the option of the holder, the Company must receive at the office or agency of the Company maintained for that purpose in accordance with the terms of
the Indenture, such Debenture with the Purchase Notice entitled “Option to Elect Repayment On Specific Dates” on the reverse thereof duly completed with such Debenture, duly endorsed for transfer, at any time from the opening of business
on the date that is 20 Business Days prior to the Purchase Date until the close of business on the Purchase Date. Debentureholders may withdraw a Purchase Notice by delivering a written notice of withdrawal to the office or agency of the Company
maintained for that purpose in accordance with the terms of the Indenture prior to the close of business on the Purchase Date. The repurchase of Debentures pursuant to this paragraph is subject to the further conditions set forth in the Indenture.

 If a Change of Control occurs at any time prior to maturity, the holders of the Debentures shall have the
right to require the Company to repurchase at such holder’s option all of such holders’ Debentures, or any portion thereof that is an integral multiple of $1,000 principal amount, on the Repurchase Date (as defined in the Indenture) in
cash at a price equal to 100% of the principal amount thereof, together with accrued interest (including Liquidated Damages, if any) to, but excluding the Repurchase Date on the Repurchase Date that is no earlier than 25 days and no later than 35
days after the date of the Company Change of Control Notice; provided, however, that, if such Repurchase Date is February 6, May 6, August 6 or November 6, the interest payable on such date shall be paid to the holder of record of the
Debentures on the preceding January 21, April 21, July 21 or October 21, respectively. The Company shall mail to all holders of record of the Debentures a notice of a Change of Control and of the repurchase right arising as a result thereof on or
before the 30th day after the occurrence of such Change of Control. For a Debenture to be so repurchased at the
option of the holder, the Company must receive at the office or agency of the Company maintained for that purpose in accordance with the terms of the Indenture, such Debenture with the Repurchase Notice entitled “Option to Elect Repayment Upon
a Change of Control” on the reverse thereof duly completed with such Debenture, duly endorsed for transfer, on or before the close of business on the Business Day that is five Business Days prior to the Repurchase Date. Debentureholders may
withdraw a Purchase Notice by delivering a written notice of withdrawal to the office or agency of the Company maintained for that purpose in accordance with the terms of the Indenture prior to the close of business on the Business Day immediately
preceding the Repurchase Date. The repurchase of Debentures pursuant to this paragraph is subject to the further conditions set forth in the Indenture. 
  
 Subject to the terms of the Indenture, the Debentureholder may convert the Debenture into shares of Common Stock at the Conversion Rate under the
circumstances set forth in Sections 15.01 of the Indenture. A Debenture in respect of which a Debentureholder has delivered a Purchase Notice or a Repurchase Notice exercising the option of such Debentureholder to require the Company to purchase
such Security may be converted only if such notice of exercise is withdrawn in accordance with the terms of the Indenture. The Conversion Rate for the Debentures on any Conversion Date shall be determined as set forth in the Indenture. 

 
 Only upon satisfaction of the conditions set forth in Article 15 of the
Indenture, the holder hereof has the right, at its option, at any time after the original issuance of any Debentures through the close of business on the final maturity date of the Debentures, or, as to all or any portion hereof called for
redemption, prior to the close of business on the Business Day immediately preceding the date fixed for redemption (unless the Company shall default in payment due upon redemption thereof), to convert the principal hereof or any portion of such
principal which is $1,000 or an integral multiple thereof into that number of shares of the Company’s Common Stock (as such shares shall be constituted at the date of conversion) obtained by dividing the principal amount of this Debenture or
portion thereof to be converted by the Conversion Rate of 42.7305 shares per $1,000 principal amount of Debenture (equivalent to a Conversion Price of approximately $23.40 per share), as may adjusted from time to time as provided in the Indenture,
upon surrender of this Debenture, together with a conversion notice as provided in the Indenture (the form entitled “Conversion Notice” on the reverse hereof), to the Company at the office or agency of the Company maintained
for that purpose in accordance with the terms of the Indenture, or at the option of such holder, the Corporate Trust Office, and, unless the shares issuable on conversion are to be issued in the same name as this Debenture, duly endorsed by, or
accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the holder or by his duly authorized attorney. 

 The Company shall satisfy its obligation with respect to conversion of the Debentures by delivering to
Debentureholders the number of shares of Common Stock issuable upon conversion, together with a cash payment in lieu of any fractional shares as provided in Section 15.03 below. Any accrued and unpaid interest to the Conversion Date will be deemed
cancelled, extinguished or forfeited upon conversion. The Company will not adjust the Conversion Rate to account for any accrued and unpaid interest or accrued or unpaid liquidated damages. If a Debenture is surrendered for conversion after the
close of business on any record date for an interest payment but prior to the close of business on the Business Day immediately preceding the corresponding Interest Payment Date, Debentureholders will receive on the Interest Payment Date interest
accrued on the Debentures, notwithstanding the conversion of the Debentures prior to the Interest Payment Date. At the time such Debentures are surrendered for conversion, Debentureholders shall pay to the Company an amount equal to the interest
that has accrued and that will be paid on the Debentures being converted on the Interest Payment Date; provided, however, that no such payment shall be required if there shall exist at the time of conversion a default in the payment of
interest on the Debentures. The preceding sentence shall not apply: (i) to Debentures called by the Company for redemption prior to August 11, 2007, (ii) to Debentures that are converted after being called by the Company for redemption after a
record date for an interest payment date but prior to the corresponding interest payment date, or (iii) if a Debentureholder surrenders Debentures for conversion between the record date for the final Interest Payment Date and the opening of business
on the final Interest Payment Date. 
  
 No fractional shares will
be issued upon any conversion, but an adjustment and payment in cash will be made, as provided in the Indenture, in respect of any fraction of a share which would otherwise be issuable upon the surrender of any Debenture or Debentures for
conversion. A Debenture in respect of which a holder is exercising its right to require a repurchase upon a Purchase Date or upon a Change of Control may be converted only if such holder withdraws its election to exercise such right in accordance
with the terms of the Indenture. Any Debentures called for redemption, unless surrendered for conversion by the holders thereof on or before the close of business on the Business Day preceding the date fixed for redemption, may be deemed to be
redeemed from the holders of such Debentures for an amount equal to the applicable redemption price, together with accrued but unpaid interest (including Liquidated Damages, if any) to (but excluding) the date fixed for redemption, by one or more
investment banks or other purchasers who may agree with the Company (i) to purchase such Debentures from the holders thereof and convert them into shares of the Company’s Common Stock and (ii) to make payment for such Debentures as aforesaid to
the Trustee in trust for the holders. 
  
 Upon due presentment for
registration of transfer of this Debenture at the office or agency of the Company maintained for that purpose in accordance with the terms of the Indenture, a new Debenture or Debentures of authorized denominations for an equal aggregate principal
amount will be issued to the transferee in exchange thereof; subject to the limitations provided in the Indenture, without charge except for any tax, assessment or other governmental charge imposed in connection therewith. 

 The Company, the Trustee, any authenticating agent, any paying agent, any conversion agent and any
Debenture registrar may deem and treat the registered holder hereof as the absolute owner of this Debenture (whether or not this Debenture shall be overdue and notwithstanding any notation of ownership or other writing hereon made by anyone other
than the Company or any Debenture registrar) for the purpose of receiving payment hereof, or on account hereof, for the conversion hereof and for all other purposes, and neither the Company nor the Trustee nor any other authenticating agent nor any
paying agent nor other conversion agent nor any Debenture registrar shall be affected by any notice to the contrary. All payments made to or upon the order of such registered holder shall, to the extent of the sum or sums paid, satisfy and discharge
liability for monies payable on this Debenture. 
  
 No recourse
for the payment of the principal of or any premium or interest on this Debenture, or for any claim based hereon or otherwise in respect hereof, and no recourse under or upon any obligation, covenant or agreement of the Company in the Indenture or
any supplemental indenture or in any Debenture, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, employee, agent, officer or director or subsidiary, as such, past, present or
future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or
otherwise, all such liability being, by acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released. 
  
 This Debenture shall be deemed to be a contract made under the laws of New York, and for all purposes shall be construed in accordance with the laws of
New York, without regard to principles of conflicts of laws. 
  
 Terms used in this Debenture and defined in the Indenture are used herein as therein defined.

thereunder as announced from time to time, for a period (the “Effectiveness Period”) until the earliest of:

 (2) the date when the Holders of Transfer Restricted Securities are able to sell all
such Transfer Restricted Securities immediately without restriction pursuant to the volume limitation provisions of Rule 144 under the Securities Act or any successor rule thereto; or

five (5) Business Days prior to such time of effectiveness shall be named as a selling securityholder in the Shelf Registration Statement and the related Prospectus in such a manner as to permit such Holder to deliver such Prospectus to purchasers
of Transfer Restricted Securities in accordance with applicable law. None of the Company’s security holders (other than the Holders of Transfer Restricted Securities) shall have the right to include any of the Company’s securities in the
Shelf Registration Statement. 
  
 (c) If the
Shelf Registration Statement or any Subsequent Shelf Registration Statement ceases to be effective for any reason at any time during the Effectiveness Period (other than because all Transfer Restricted Securities registered thereunder shall have
been resold pursuant thereto or shall have otherwise ceased to be Transfer Restricted Securities), the Company shall use its reasonable efforts to obtain the prompt withdrawal of any order suspending the effectiveness thereof, and in any event shall
within thirty (30) days of such cessation of effectiveness amend the Shelf Registration Statement in a manner reasonably expected to obtain the withdrawal of the order suspending the effectiveness thereof, or file an additional Shelf Registration
Statement covering all of the securities that as of the date of such filing are Transfer Restricted Securities (a “Subsequent Shelf Registration Statement”). If a Subsequent Shelf Registration Statement is filed, the Company shall

related Prospectus, it will do so only in accordance with this Section 2(e) and Section 4(b). Each Holder wishing to sell Transfer Restricted Securities pursuant to a Shelf Registration Statement and related Prospectus agrees to deliver a Notice and
Questionnaire to the Company at least five (5) Business Days prior to the effectiveness of the Shelf Registration Statement. From and after the date the Shelf Registration Statement is declared effective, the Company shall, within a reasonably
practicable period of time not to be later than 90 days after the date a Notice and Questionnaire is delivered: 
  
 (i) if required by applicable law, file with the SEC a post-effective amendment to the Shelf Registration Statement or prepare and, if
required by applicable law, file a supplement to the related Prospectus or a supplement or amendment to any document incorporated therein by reference or file any other required document so that the Holder delivering such Notice and Questionnaire is
named as a selling securityholder in the Shelf Registration Statement and the related Prospectus in such a manner as to permit such Holder to deliver such Prospectus to purchasers of the Transfer Restricted Securities in accordance with applicable
law and, if the Company shall file a post-effective amendment to the Shelf Registration Statement, use its reasonable efforts to cause such post-effective amendment to be declared effective under the Securities Act as promptly as is practicable, but
in any event by the date (the “Amendment Effectiveness Deadline Date”) that is forty-five (45) days after the date such post-effective amendment is filed; 
  
 (ii) provide such Holder copies of any documents filed pursuant to Section 2(e)(i); 
  
 (iii) notify such Holder as promptly as practicable after
the effectiveness under the Securities Act of any post-effective amendment filed pursuant to Section 2(e)(i); 

 provided that if such Notice and Questionnaire is delivered during a Suspension Period, the Company shall so
inform the Holder delivering such Notice and Questionnaire and shall take the actions set forth in clauses (i), (ii) and (iii) above upon expiration of the Suspension Period in accordance with Section 4(b). Notwithstanding anything contained herein
to the contrary, (i) the Company shall be under no obligation to name any Holder that is not a Notice Holder as a selling securityholder in any Registration Statement or related Prospectus and (ii) the Amendment Effectiveness Deadline Date shall be
extended by up to ten (10) Business Days from the expiration of a Suspension Period (and the Company shall incur no obligation to pay Liquidated Damages during such extension) if such Suspension Period shall be in effect on the Amendment
Effectiveness Deadline Date; and provided further, that after the date of effectiveness of the Shelf Registration Statement, the Company shall not be obligated to file more than one post-effective amendment or supplement in any 90-day period
(measured from the date any previous post effective amendment or supplement has been filed, or in the case of the first post effective amendment or supplement, the date the first Notice and Questionnaire is delivered to the Company after the date of
effectiveness) for the purpose of naming Holders as selling securityholders who were not so named in the Shelf Registration Statement at the time of effectiveness. 
  
 3. Liquidated Damages. 
  
 (a) If: 
  
 (i) the Shelf Registration Statement is not filed with the Commission prior to or on the Shelf Filing Deadline; 
  
 (ii) the Shelf Registration Statement has not been declared
effective by the Commission prior to or on the Effectiveness Target Date; 
  
 (iii) the Company has failed to perform its obligations set forth in Section 2(e) within the time period required therein; 
  
 (iv) any post-effective amendment to a Shelf Registration filed pursuant to Section 2(e)(i) has not become effective under the Securities
Act on or prior to the Amendment Effectiveness Deadline Date; 
  
 (v) except as provided in Section 4(b)(i) hereof, the Shelf Registration Statement is filed and declared effective but, during the Effectiveness Period, shall thereafter cease to be 

 
effective or fail to be usable for its intended purpose without being succeeded within five (5) Business Days by a post-effective amendment to the Shelf
Registration Statement, a supplement to the Prospectus or a report filed with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act that cures such failure and, in the case of a post-effective amendment, is itself declared
effective within such five (5) Business Day period; or 
  
 (vi) (A) prior to or on the 45th or 60th day, as applicable under the provisions of Section 4(b), of any Suspension Period, such suspension has not been terminated or (B) Suspension Periods exceed an aggregate of 90 days in any 360 day
period, 
  
 (each such event referred to in foregoing clauses (i) through (v), a
“Registration Default”), the Company hereby agrees to pay interest (“Liquidated Damages”) with respect to the Transfer Restricted Securities from and including the day following the Registration Default to but
excluding the earlier of (1) the day on which the Registration Default has been cured and (2) the date the Shelf Registration Statement is no longer required to be kept effective, accruing at a rate: 
  
 (A) in respect of the Debentures, to each holder of
Debentures, (x) with respect to the first 90-day period during which a Registration Default shall have occurred and be continuing, equal to 0.25% per annum of the aggregate principal amount of the Debentures, and (y) with respect to the period
commencing on the 91st day following the day the Registration Default shall have occurred and be continuing, equal to 0.50% per annum of the aggregate principal amount of the Debentures; provided that in no event shall Liquidated Damages
accrue at a rate per year exceeding 0.50% of the aggregate principal amount of the Debentures; and 
  
 (B) in respect of any shares of Common Stock, to each holder of shares of Common Stock issued upon conversion of Debentures, (x) with
respect to the first 90-day period in which a Registration Default shall have occurred and be continuing, equal to 0.25% per annum of the aggregate principal amount of each Debenture converted, and (y) with respect to the period commencing on the
91st day following the day the Registration Default shall have occurred and be continuing, equal to 0.50% per annum of the aggregate principal amount of each Debenture converted; provided that in no event shall Liquidated Damages accrue at a
rate per year exceeding 0.50% of the aggregate principal amount of the converted Debentures. 

 (b) All accrued Liquidated Damages shall be paid in arrears to Record Holders by the
Company on each Liquidated Damages Payment Date. Upon the cure of all Registration Defaults relating to any particular Debenture or share of Common Stock, the accrual of Liquidated Damages with respect to such Debenture or share of Common Stock will
cease. 
  
 All obligations of the Company set forth in this
Section 3 that are outstanding with respect to any Transfer Restricted Security at the time such security ceases to be a Transfer Restricted Security shall survive until such time as all such obligations with respect to such Transfer Restricted
Security shall have been satisfied in full. 
  
 The Liquidated
Damages set forth above shall be the exclusive monetary remedy available to the Holders of Transfer Restricted Securities for each Registration Default. 
  
 4. Registration Procedures. 
  
 (a) In connection with the Shelf Registration Statement, the Company shall comply with all the provisions of Section 4(b) hereof and shall
prepare and file with the Commission a Shelf Registration Statement relating to the registration on any appropriate form under the Securities Act in accordance with Section 2 hereof. 
  
 (b) In connection with the Shelf Registration Statement and any Prospectus required by this Agreement to
permit the sale or resale of Transfer Restricted Securities, the Company shall: 
  
 (i) Subject to any notice by the Company in accordance with this Section 4(b) of the existence of any fact or event of the kind described
in Section 4(b)(iii)(D), use its reasonable efforts to keep the Shelf Registration Statement continuously effective during the Effectiveness Period; upon the occurrence of any event that would cause the Shelf Registration Statement or the Prospectus
contained therein (A) to contain a material misstatement or omission or (B) not to be effective and usable for resale of Transfer Restricted Securities during the Effectiveness Period, the Company shall file promptly an appropriate amendment to the
Shelf Registration Statement, a supplement to the Prospectus or a report filed with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act, in the case of clause (A), correcting any such 

 
misstatement or omission, and, in the case of either clause (A) or (B), use its reasonable efforts to cause such amendment to be declared effective and the
Shelf Registration Statement and the related Prospectus to become usable for resale of Transfer Restricted Securities during the Effectiveness Period as soon as practicable thereafter. Notwithstanding the foregoing, the Company may suspend the use
of the Prospectus and may elect to suspend the effectiveness of the Shelf Registration Statement by written notice to the Holders for a period not to exceed an aggregate of 45 days in any 90-day period (each such period, a “Suspension
Period”) if: 
  
 (x) an event occurs
and is continuing as a result of which the Shelf Registration Statement, the Prospectus, any amendment or supplement thereto, or any document incorporated by reference therein would, in the Company’s judgment, contain an 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; and 
  
 (y) the Company determines in good faith that the disclosure of such event at such time would be seriously detrimental to the Company and
its subsidiaries; 
  
 provided that, in the event the
disclosure relates to a previously undisclosed proposed or pending material business transaction, the disclosure of which the Company determines in good faith would be reasonably likely to impede the Company’s ability to consummate such
transaction, the Company may extend a Suspension Period from 45 days to 60 days; provided, however, that Suspension Periods shall not exceed an aggregate of 90 days in any 360-day period. The Company shall not be required to specify in the written
notice to the Holders the nature of the event giving rise to the Suspension Period. 
  
 (ii) Prepare and file with the Commission such amendments and post-effective amendments to the Shelf Registration Statement as may be
necessary to keep the Shelf Registration Statement effective during the Effectiveness Period; cause the Prospectus to be supplemented by any required Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the Securities
Act, and to comply fully with the applicable provisions of Rules 424 and 430A under the Securities Act in a timely manner; and comply with the provisions 

 
of the Securities Act with respect to the disposition of all securities covered by the Shelf Registration Statement during the applicable period in
accordance with the intended method or methods of distribution by the sellers thereof set forth in the Shelf Registration Statement or supplement to the Prospectus. 
  
 (iii) Advise the selling Holders promptly and, if requested by such selling Holders, to confirm such advice
in writing, except as provided in clause (D) below: 
  
 (A) when the Prospectus or any Prospectus supplement or post-effective amendment has been filed, and, with respect to the Shelf Registration Statement or any post-effective amendment thereto, when the same has become effective; 

 
 (B) of any request by the Commission for amendments to
the Shelf Registration Statement or amendments or supplements to the Prospectus or for additional information relating thereto; 
  
 (C) of the issuance by the Commission of any stop order suspending the effectiveness of the Shelf Registration Statement under the
Securities Act or of the suspension by any state securities commission of the qualification of the Transfer Restricted Securities for offering or sale in any jurisdiction, or the initiation of any proceeding for any of the preceding purposes; or

  
 (D) of the existence of any fact or the
happening of any event, during the Effectiveness Period, that makes any statement of a material fact made in the Shelf Registration Statement, the Prospectus, any amendment or supplement thereto, or any document incorporated by reference therein
untrue, or that requires the making of any additions to or changes in the Shelf Registration Statement or the Prospectus in order to make the statements therein not misleading. 
  
 If at any time the Commission shall issue any stop order suspending the effectiveness of the Shelf Registration Statement,
or any state securities commission or other regulatory authority shall issue an order suspending the qualification or exemption from qualification of the Transfer Restricted Securities under state securities or Blue Sky laws, the Company shall use
its reasonable efforts to obtain the withdrawal or lifting of such order at the earliest possible time and will provide to each Holder who is named in the Shelf Registration Statement prompt notice of the withdrawal of any such order. 

 (iv) Make available at reasonable times for inspection by one or more representatives of
the selling Holders, designated in writing by a Majority of Holders whose Transfer Restricted Securities are included in the Shelf Registration Statement, and any attorney or accountant retained by such selling Holders, all financial and other
records, pertinent corporate documents and properties of the Company as shall be reasonably necessary to enable them to conduct a reasonable investigation within the meaning of Section 11 of the Securities Act, and cause the Company’s officers,
directors, managers and employees to supply all information reasonably requested by any such representative or representatives of the selling Holders, attorney or accountant in connection therewith; provided, however, that the Company shall
have no obligation to deliver information to any selling Holder or representative pursuant to this Section 4(b)(iv) unless such selling Holder or representative shall have executed and delivered a confidentiality agreement in a form reasonably
acceptable to the Company relating to such information. 
  
 (v) If requested by any selling Holders, promptly incorporate in the Shelf Registration Statement or Prospectus, pursuant to a supplement or post-effective amendment if necessary, such information as such selling
Holders may reasonably request to have included therein, including, without limitation, information relating to the “Plan of Distribution” of the Transfer Restricted Securities. 
  
 (vi) Furnish to each selling Holder upon such Holder’s
written request, without charge, at least one copy of the Shelf Registration Statement, as first filed with the Commission, and of each amendment thereto (and any documents incorporated by reference therein or exhibits thereto (or exhibits
incorporated in such exhibits by reference) as such Person may request). 
  
 (vii) Deliver to each selling Holder, without charge, as many copies of the Prospectus (including each preliminary Prospectus) and any amendment or supplement thereto as such Persons reasonably may request; subject to
any notice by the Company in accordance with this Section 4(b) of the existence of any fact or event of the kind described in Section 4(b)(iii)(D) or 4(b)(i), the Company hereby consents to the use of the Prospectus and any amendment or supplement
thereto by each of the selling Holders in connection with the offering and the sale of the Transfer Restricted Securities covered by the Prospectus or any amendment or supplement thereto. 

 (viii) Before any public offering of Transfer Restricted Securities, cooperate with the
selling Holders and their counsel in connection with the registration and qualification of the Transfer Restricted Securities under the securities or Blue Sky laws of such jurisdictions in the United States as the selling Holders may reasonably
request and do any and all other acts or things necessary or advisable to enable the disposition in such jurisdictions of the Transfer Restricted Securities covered by the Shelf Registration Statement; provided, however, that the Company
shall not be required (A) to register or qualify as a foreign corporation or a dealer of securities where it is not now so qualified or to take any action that would subject it to the service of process in any jurisdiction where it is not now so
subject or (B) to subject itself to general or unlimited service of process or to taxation in any such jurisdiction if it is not now so subject. 
  
 (ix) Cooperate with the selling Holders to facilitate the timely preparation and delivery of certificates representing Transfer Restricted
Securities to be sold and not bearing any restrictive legends (unless required by applicable securities laws); and enable such Transfer Restricted Securities to be in such denominations and registered in such names as the Holders may reasonably
request at least two (2) Business Days before any sale of Transfer Restricted Securities made by such Holders. 
  
 (x) Subject to Section 4(b)(i) hereof and the provision in clause (viii) above, use its reasonable efforts to cause the Transfer
Restricted Securities covered by the Shelf Registration Statement to be registered with or approved by such other U.S. governmental agencies or authorities as may be necessary to enable the seller or sellers thereof to consummate the disposition of
such Transfer Restricted Securities. 
  
 (xi)
Subject to Section 4(b)(i) hereof, if any fact or event contemplated by Section 4(b)(iii)(D) hereof shall exist or have occurred, use its reasonable efforts to prepare a supplement or post-effective amendment to the Shelf Registration Statement or
related Prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to the purchasers of Transfer Restricted Securities, the Prospectus will not contain an untrue statement of a
material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they are made, not misleading. 

 (xii) Provide CUSIP numbers for all Transfer Restricted Securities not later than the
effective date of the Shelf Registration Statement and provide the Trustee under the Indenture with certificates for the Debentures that are in a form eligible for deposit with The Depository Trust Company. 
  
 (xiii) Cooperate and assist in any filings required to be
made with the NASD and in the performance of any due diligence investigation by any underwriter that is required to be retained in accordance with the rules and regulations of the NASD. 
  
 (xiv) Subject to Section 4(b)(i) hereof, otherwise use its reasonable efforts to comply with all applicable
rules and regulations of the Commission and all reporting requirements under the rules and regulations of the Exchange Act. 
  
 (xv) Cause the Indenture to be qualified under the TIA not later than the effective date of the Shelf Registration Statement required by
this Agreement, and, in connection therewith, cooperate with the Trustee and the holders of Debentures to effect such changes to the Indenture as may be required for such Indenture to be so qualified in accordance with the terms of the TIA; and
execute and use its reasonable efforts to cause the Trustee thereunder to execute all documents that may be required to effect such changes and all other forms and documents required to be filed with the Commission to enable such Indenture to be so
qualified in a timely manner. 
  
 (xvi) Cause all
Common Stock covered by the Shelf Registration Statement to be listed or quoted, as the case may be, on each securities exchange or automated quotation system on which Common Stock is then listed or quoted. 
  
 (xvii) Provide to each Holder upon written request each
document filed with the Commission pursuant to the requirements of Section 13 and Section 15 of the Exchange Act after the effective date of the Shelf Registration Statement, unless such document is available through the Commission’s EDGAR
system. 
  
 (c) Each Holder agrees by acquisition
of a Transfer Restricted Security that, upon receipt of any notice (a “Suspension Notice”) from the Company of the existence of any fact of the kind described in Section 4(b)(iii)(D) or 4(b)(i) hereof, such Holder will forthwith
discontinue disposition of Transfer Restricted Securities pursuant to the Shelf Registration Statement until: 
  
 (i) such Holder has received copies of the supplemented or amended Prospectus contemplated by Section 4(b)(xi) hereof; or 

 (ii) such Holder is advised in writing by the Company that the use of the Prospectus may
be resumed, and has received copies of any additional or supplemental filings that are incorporated by reference in the Prospectus. 
  
 If so directed by the Company, each Holder will deliver to the Company (at the Company’s expense) all copies, other than permanent file copies then
in such Holder’s possession, of the Prospectus covering such Transfer Restricted Securities that was current at the time of receipt of such Suspension Notice. 
  
 (d) Each Holder agrees, by acquisition of the Transfer Restricted Securities, that no Holder shall be
entitled to sell any of such Transfer Restricted Securities pursuant to a Registration Statement or to receive a Prospectus relating thereto, unless such Holder has furnished the Company with a Notice and Questionnaire as required pursuant to
Section 2(e) hereof (including the information required to be included in such Notice and Questionnaire) and the information set forth in the next sentence. Each Notice Holder agrees promptly to furnish to the Company all information required to be
disclosed in order to make the information previously furnished to the Company by such Notice Holder not misleading and any other information regarding such Notice Holder and the distribution of such Transfer Restricted Securities as the Company may
from time to time reasonably request in writing. Any sale of any Transfer Restricted Securities by any Holder shall constitute a representation and warranty by such Holder that the information relating to such Holder and its plan of distribution is
as set forth in the Prospectus delivered by such Holder in connection with such disposition, that such Prospectus does not as of the time of such sale contain any untrue statement of a material fact relating to or provided by such Holder or its plan
of distribution and that such Prospectus does not as of the time of such sale omit to state any material fact relating to or provided by such Holder or its plan of distribution necessary to make the statements in such Prospectus, in the light of the
circumstances under which they were made, not misleading. 

 5. Registration Expenses. 
  
 All expenses incident to the Company’s performance of or compliance with this Agreement shall be borne by the Company
regardless of whether a Shelf Registration Statement becomes effective, including, without limitation: 
  
 (i) all registration and filing fees and expenses (including filings made with the NASD); 
  
 (ii) all fees and expenses of compliance with federal
securities and state Blue Sky or securities laws; 
  
 (iii) all expenses of printing (including printing of Prospectuses and certificates for the Common Stock to be issued upon conversion of the Debentures) and the Company’s expenses for messenger and delivery services and telephone;

  
 (iv) all fees and disbursements of counsel to
the Company; 
  
 (v) all application and filing
fees in connection with listing (or authorizing for quotation) the Common Stock on a national securities exchange or automated quotation system pursuant to the requirements hereof; and 
  
 (vi) all fees and disbursements of independent certified public accountants of the Company. 
  
 The Company shall bear its internal expenses (including, without limitation,
all salaries and expenses of their officers and employees performing legal, accounting or other duties), the expenses of any annual audit and the fees and expenses of any Person, including special experts, retained by the Company. 
  
 6. Indemnification And Contribution. 
  
 (a) The Company agrees to indemnify and hold harmless each
Holder of Transfer Restricted Securities (including each Initial Purchaser), such Holder’s directors, officers, and employees and each person, if any, who controls any such Holder within the meaning of the Securities Act (each, an
“Indemnified Holder”), against any loss, claim, damage, liability or expense, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to resales of the
Transfer Restricted Securities), to which such Indemnified Holder may become subject, insofar as any such loss, claim, damage, liability or action arises out of, or is based upon: 
  
 (i) any untrue statement or alleged untrue statement of a material fact contained in (A) the Shelf
Registration Statement as originally filed or in any amendment thereof, in any 

 
Prospectus, or in any amendment or supplement thereto or (B) any blue sky application or other document or any amendment or supplement thereto prepared or
executed by the Company (or based upon written information furnished by or on behalf of the Company expressly for use in such blue sky application or other document or amendment on supplement) filed in any jurisdiction specifically for the purpose
of qualifying any or all of the Transfer Restricted Securities under the securities law of any state or other jurisdiction (such application or document being hereinafter called a “Blue Sky Application”); or 
  
 (ii) the omission or alleged omission to state therein any
material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, 
  
 and agrees to reimburse each Indemnified Holder promptly upon demand for any legal or other expenses reasonably incurred by
such Indemnified Holder in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the Company shall not be liable in any such case to the
extent that any such loss, claim, damage, liability, expense or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information
furnished to the Company by or on behalf of such Holder (or its related Indemnified Holder) specifically for use therein. The foregoing indemnity agreement is in addition to any liability which the Company may otherwise have. 
  
 (b) Each Holder, severally and not jointly, agrees to
indemnify and hold harmless the Company, its directors, officers and employees and each person, if any, who controls the Company within the meaning of the Securities Act to the same extent as the foregoing indemnity from the Company to each such
Holder, but only with reference to written information relating to such Holder furnished to the Company by or on behalf of such Holder specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement set
forth in this Section shall be in addition to any liabilities which any such Holder may otherwise have. In no event shall any Holder, its directors, officers or any person who controls such Holder be liable or responsible for any amount in excess of
the amount by which the net proceeds received by such Holder with respect to its sale of Transfer Restricted Securities pursuant to a Shelf Registration Statement exceeds the amount of any damages that such Holder, its directors, officers or any
person who controls such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. 

 (c) Promptly after receipt by an indemnified party under this Section 6 of notice of any
claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 6, notify the indemnifying party in writing of the claim or the commencement of that
action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 6 except to the extent it has been materially prejudiced by such failure and,
provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 6. If any such claim or action is brought against an
indemnified party, and it notifies the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense
thereof with counsel satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the
indemnified party under this Section 6 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the indemnified
parties shall have the right to employ a single counsel to represent jointly the indemnified parties and their officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be
sought by the indemnified parties against the indemnifying party under this Section 6 if the indemnified party shall have been advised by legal counsel that there may be one or more legal defenses available to such indemnified party and their
respective officers, employees and controlling persons that are different from or additional to those available to the indemnifying party, and in that event, the fees and expenses of such separate counsel shall be paid by the indemnifying party. No
indemnifying party shall: 
  
 (i) without the
prior written consent of the indemnified parties (which consent shall not be unreasonably withheld) settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect
of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action), unless such settlement, compromise or consent includes an unconditional release of
such indemnified party from all liability arising out of such claim, action, suit or proceeding, or 
  
 (ii) be liable for any settlement of any such action effected without its written consent (which consent shall not be 

 
unreasonably withheld), but if settled with its written consent or if there be a final judgment for the plaintiff in any such action, the indemnifying party
agrees to indemnify and hold harmless any indemnified party from and against any loss of liability by reason of such settlement or judgment in accordance with this Section 6. 
  
 (d) The indemnifying party under this Section shall not be liable for any settlement of any proceeding
effected without its written consent, which shall not be withheld unreasonably, but if settled with such consent or if there is a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss,
claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have validly requested an indemnifying party to reimburse the indemnified party for fees
and expenses of counsel as contemplated by Section 6(c) hereof, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days
after receipt by such indemnifying party of the aforesaid valid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such valid request prior to the date of such settlement. No indemnifying
party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or
could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (x) includes an unconditional release of such indemnified party from all liability on claims that
are the subject matter of such action, suit or proceeding and (y) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. 
  
 (e) If the indemnification provided for in this Section 6
shall for any reason be unavailable or insufficient to hold harmless an indemnified party under Section 6(a) or 6(b) in respect of any loss, claim, damage or liability (or action in respect thereof) referred to therein, each indemnifying party
shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability (or action in respect thereof): 
  
 (i) in such proportion as is appropriate to reflect the
relative benefits received by the Company from the offering and sale of the Transfer Restricted Securities on the one hand and a Holder with respect to the sale by such Holder of the Transfer Restricted Securities on the other, or 

 (ii) if the allocation provided by Section (6)(e)(i) is not permitted by applicable law,
in such proportion as is appropriate to reflect not only the relative benefits referred to in Section 6(e)(i) but also the relative fault of the Company on the one hand and the Holders on the other in connection with the statements or omissions or
alleged statements or alleged omissions that resulted in such loss, claim, damage or liability (or action in respect thereof), as well as any other relevant equitable considerations. 
  
 The relative benefits received by the Company on the one hand and a Holder on the other with respect to such offering and
such sale shall be deemed to be in the same proportion as the total net proceeds from the offering of the Debentures purchased under the Purchase Agreement (before deducting expenses) received by the Company, on the one hand, bear to the total
proceeds received by such Holder with respect to its sale of Transfer Restricted Securities on the other. The relative fault of the parties shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Holders on the other, the intent of the parties and their relative knowledge, access to information and opportunity to
correct or prevent such statement or omission. The Company and each Holder agree that it would not be just and equitable if the amount of contribution pursuant to this Section 6(e) were determined by pro rata allocation or by any other method
of allocation that does not take into account the equitable considerations referred to in the first sentence of this paragraph (e). 
  
 The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof,
referred to above in this Section 6 shall be deemed to include, for purposes of this Section 6, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending or preparing to defend any such
action or claim. 
  
 Notwithstanding the
provisions of this Section 6, no Holder shall be required to contribute any amount in excess of the amount by which the net proceeds received by such Holder with respect to its sale of Transfer Restricted Securities exceeds the amount of any damages
which such Holder has otherwise been required to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The Holders’ obligations to contribute as provided in this Section 6(d) are several and not joint. 

 (f) The provisions of this Section 6 shall remain in full force and effect, regardless of
any investigation made by or on behalf of any Holder or the Company or any of the officers, directors or controlling persons referred to in Section 6 hereof, and will survive the sale by a Holder of Transfer Restricted Securities. 
  
 7. Rule 144A and Rule 144. The Company agrees with each Holder, for so
long as any Transfer Restricted Securities remain outstanding and during any period in which the Company (i) is not subject to Section 13 or 15(d) of the Exchange Act, to make available, upon request of any Holder, to such Holder or beneficial owner
of Transfer Restricted Securities in connection with any sale thereof and any prospective purchaser of such Transfer Restricted Securities designated by such Holder or beneficial owner, the information required by Rule 144A(d)(4) under the
Securities Act in order to permit resales of such Transfer Restricted Securities pursuant to Rule 144A, and (ii) is subject to Section 13 or 15 (d) of the Exchange Act, to make all filings required thereby in a timely manner in order to permit
resales of such Transfer Restricted Securities pursuant to Rule 144. 
  
 8. Miscellaneous. 
  
 (a)
Remedies. The Company acknowledges and agrees that any failure by the Company to comply with its obligations under Section 2 hereof may result in material irreparable injury to the Initial Purchasers or the Holders for which there is no
adequate remedy at law, that it will not be possible to measure damages for such injuries precisely, and that, in the event of any such failure, the Initial Purchasers or any Holder may seek such relief as may be required to specifically enforce the
Company’s obligations under Section 2 hereof. 
  
 (b) No Inconsistent Agreements. The Company will not on or after the date hereof, enter into any agreement with respect to its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise
conflicts with the provisions hereof. In addition, the Company shall not grant to any of its securityholders (other than the Holders of Transfer Restricted Securities in such capacity) the right to include any of its securities in the Shelf
Registration Statement provided for in this Agreement other than the Transfer Restricted Securities. The Company has not previously entered into any agreement (which has not expired or been terminated) granting any registration rights with respect
to its securities to any Person, which rights conflict with the provisions hereof. 

 (c) Amendments and Waivers. This Agreement may not be amended, modified or
supplemented, and waivers or consents to or departures from the provisions hereof may not be given, unless the Company has obtained the written consent of a Majority of Holders. Notwithstanding the foregoing, a waiver or consent to depart from the
provisions hereof, with respect to a matter, which relates exclusively to the rights of Holders whose securities are being sold pursuant to a Shelf Registration Statement and does not directly or indirectly adversely affect the rights of other
Holders, may be given by the Majority Holders, determined on the basis of Debentures being sold rather than registered under such Shelf Registration Statement. 
  

(d) Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand-delivery,
first-class mail (registered or certified, return receipt requested), telex, facsimile transmission, or air courier guaranteeing overnight delivery: 
  
 (i) if to a Holder, at the address set forth on the records of the registrar under the Indenture or the transfer agent of the Common
Stock, as the case may be; and 
  
 (ii) if to the
Company, initially at its address set forth in the Purchase Agreement, 
  
 With a copy to: 
  
 Latham & Watkins LLP 
 135 Commonwealth Drive 
 Menlo Park, California 94025 
 Fax No.: (650) 433-2600 
 Attn: Christopher L. Kaufman 
  
 All such notices and communications shall be deemed to have
been duly given: at the time delivered by hand, if personally delivered; five Business Days after being deposited in the mail, postage prepaid, if mailed; when answered back, if telexed; when receipt acknowledged, if transmitted by facsimile; and on
the next Business Day, if timely delivered to an air courier guaranteeing overnight delivery. 
  
 Any party hereto may change the address for receipt of communications by giving written notice to the others. 
  
 (e) Successors and Assigns. This Agreement shall
inure to the benefit of and be binding upon the successors, assigns and transferees of each of the parties, including without limitation and without the need for an express assignment, subsequent Holders of Transfer Restricted Securities,
provided, however, that nothing contained herein shall be 

 
deemed to permit any assignment, transfer or other disposition of Transfer Restricted Securities in violation of the terms of the Purchase Agreement or the
Indenture. If any transferee of any Holder shall acquire Transfer Restricted Securities, in any manner, whether by operation of law or otherwise, such Transfer Restricted Securities shall be held subject to all the terms of this Agreement, and by
taking and holding such Transfer Restricted Securities such person shall be conclusively deemed to have agreed to be bound by and to perform all of the terms and provisions of this Agreement. 
  
 (f) Counterparts. This Agreement may be executed in
any number of counterparts and by the parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. 
  
 (g) Debentures Held by the Company or Their
Affiliates. Whenever the consent or approval of Holders of a specified percentage of Transfer Restricted Securities is required hereunder, Transfer Restricted Securities held by the Company or its Affiliates (other than subsequent Holders if
such subsequent Holders are deemed to be Affiliates solely by reason of their holding of such Debentures) shall not be counted in determining whether such consent or approval was given by the Holders of such required percentage. 
  
 (h) Headings. The headings in this Agreement are for
convenience of reference only and shall not limit or otherwise affect the meaning hereof. 
  
 (i) Governing Law. This Agreement shall be governed by and construed in accordance with the law of the State of New York.

  
 (j) Severability. If any one or more
of the provisions contained herein, or the application thereof in any circumstance, is held invalid, illegal or unenforceable, the validity, legality and enforceability of any such provision in every other respect and of the remaining provisions
contained herein shall not be affected or impaired thereby, it being intended that all of the rights and privileges of the parties shall be enforceable to the fullest extent permitted by law. 
  
 (k) Entire Agreement. This Agreement, together with
the Purchase Agreement and the Indenture, is intended by the parties as a final expression of their agreement and intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject
matter contained herein. There are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein with respect to the registration rights granted by the Company with respect to the Transfer Restricted
Securities. This Agreement supersedes all prior agreements and understandings between the parties with respect to such subject matter. 

 IN WITNESS WHEREOF, the parties have executed this Agreement as of the date first written above.
