Exhibit 10.26  

 
 

Groundwater Restoration Performance Agreement    
    

        This Agreement is entered into by the Texas Commission on Environmental Quality ("TCEQ"), the Texas Department of Health ("TDH"), URI, Inc. ("URI"), and
the United States Fidelity & Guaranty Company ("USF&G") for the period from March 1, 2004 to August 31, 2007. 

Recitals  

        A.    URI
is the owner and operator of the Kingsville Dome Mine site located in Kleberg County and the Rosita Mine site located Duval County, Texas. 

        B.    The
following are the outstanding Bonds issued by USF&G on behalf of the Kingsville Dome and Rosita mine sites to provide assurance that funds will be available when
needed for groundwater restoration, decommissioning, and, if applicable, for the long term care of the facilities. 

        On
June 23, 2000, USF&G issued to TDH on behalf of the Kingsville Dome mine site the Surety Bond Rider to Performance Guarantee Bond (Bond
No. 41-0130-40028-96-6) that has been in
effect since December 2, 1996, in the penal sum of One Million Seven Hundred Forty One Thousand Five Hundred Forty Two Dollars ($1,741,542.00). 

        On
June 23, 2000, USF&G issued to TDH on behalf of the Rosita mine site the Surety Bond Rider to Performance Guarantee Bond (Bond
No. 41-0130-40040-96-6) that has been in effect since November 26, 1996, in the penal sum of One Million Nine Hundred Nine Thousand Six
Hundred Forty Three Dollars ($1,909,643.00). 

        On
June 23, 2000, USF&G issued to TDH on behalf of the Kingsville Dome mine site the Surety Bond Rider to Performance Guarantee Bond (Bond No.
41-0130-17602-98-5) that has been in effect since June 9, 1998 in the penal sum of Six Hundred Ninety Nine Thousand Four Hundred Fifty Eight
Dollars ($699,458.00). 

        C.    URI,
to induce USF&G, as Surety, to execute the Bonds on behalf of URI, executed and delivered a Master Surety Agreement for the benefit of Surety, dated
November 25, 1996, pursuant to which URI, agreed to exonerate, hold harmless, indemnify and keep indemnified USF&G from and against any and all demands, claims, liabilities, losses and expenses
of whatsoever kind or nature (including but not limited to, interest, court costs and counsel fees) imposed upon, sustained, or incurred by USF&G by reason of: (1) USF&G having executed,
provided or procured Bonds in behalf of URI, Inc., or (2) URI, Inc.'s failure to perform or comply with any of the provisions of the Master Surety Agreement. By this document,
URI, Inc. reaffirms its indemnity obligations under the Master Surety Agreement. 

        D.    USF&G
may have certain defenses to claims made under the Bonds, and it expressly reserves any and all defenses it may have or hereinafter acquire. 

        E.    TCEQ,
TDH, URI, and USF&G entered into the Kingsville Dome and Rosita Mines Agreement on October 11, 2000, the Second Kingsville Dome and Rosita Mines Agreement on
January 1, 2002, the Third Kingsville Dome and Rosita Mines Agreement on May 1, 2002, and the Third Kingsville Dome and Rosita Mines Agreement Extensions on December 1, 2002, and
February 1, 2003, that allowed for, and resulted in, the reduction of outstanding bond amounts to provide funds needed for groundwater restoration of the facilities. By this Agreement, the
Agencies agree that they cannot enforce in excess of the remaining amounts set forth below against USF&G if needed for groundwater restoration, decommissioning, and, if applicable, for the long term
care of the facilities.

        F.     As
of January 16, 2002, TDH's estimate of financial security for surface remediations of the Kingsville Dome and Rosita mine sites is One Million Three Hundred
Ninety Thousand Dollars ($1,390,000). URI's estimate of the surface remediation cost at the same locations is One Million One Hundred Fifty One Thousand One Hundred Sixty Two Dollars ($1,151,162). 

        G.    By
letter dated January 16, 2002 TDH informed URI that additional financial security in the amount of Three Million Five Hundred Twenty Eight Thousand Six Hundred
Sixty Six Dollars ($3,528,666) would be required to cover the additional estimated costs of groundwater restoration and that these may be reduced according to the terms of the Kingsville Dome and
Rosita Mines Agreement as appropriate. Currently, URI estimates the remaining groundwater restoration cost estimate at the Kingsville Dome and Rosita mine sites to be Three Million Three Hundred
Eighty Four Thousand Dollars ($3,384,000). 

        H.    This
Agreement is entered by USF&G and the Agencies at the request of URI, which has acknowledged that it is financially unable to post additional financial security for
groundwater restoration and simultaneously continue groundwater restoration at the Kingsville Dome and Rosita mine sites and cannot be in compliance with 25 TAC § 289.260(o)
without this Agreement. This Agreement does not replace or supersede any licenses, permits, or regulatory requirements already in place but does provide
acceptable financial security as required by License L03653 Condition 25 and 25 TAC § 289.260(o) for the Kingsville Dome and Rosita mine sites until September 1, 2001.
Compliance with Attachments A and B does not constitute final groundwater restoration. Final groundwater restoration is controlled by 30 TAC §331.107 and TCEQ's Permit Restoration
Tables. It is not intended that the terms of this Agreement affect or change the responsibilities of TDH and TCEQ as set forth in the Memorandum of Understanding between the agencies found at
25 TAC § 289.101(f). 

        I.     URI
has entered into new long term sales contracts that will provide funding to conduct groundwater restoration from previous activities at the Kingsville Dome and Rosita
mine sites. 

        J.     The
purpose of this Agreement is, variously, to (1) protect the public health and environment by assuring continuation of groundwater restoration of the Mines;
(2) allow URI a corresponding reduction in the estimated cost of groundwater restoration of the Mines. 

        Now,
therefore, the parties agree as follows: 

        1.     Incorporation. The above Recitals are hereby incorporated into this Agreement. 

        2.     Definitions. The following terms shall have the meanings defined below: 

        2.1   "Agencies"
means collectively TCEQ and TDH. 

        2.2   "Bonds"
means the Bonds described in Recital B. 

        2.3   "Restoration
Cost Estimate" means the estimated costs of groundwater restoration based on the unit quantity of water requiring treatment and the actual costs for this
processing that was accounted for under the terms of the Kingsville Dome and Rosita Mines Agreement and the Second Kingsville Dome and Rosita Mines Agreement. 

        2.4   "Effective
Date" means March 1, 2004. 

2

 

        2.5   "Mines"
means the Kingsville Dome mine site and the Rosita mine site collectively. 

        2.6   "Surety"
means United States Fidelity & Guaranty Company. 

        2.7   "TDH"

        2.9   "URI"
means URI, Inc. 

        2.10 "USF&G"
means the United States Fidelity & Guaranty Company. 

        3.     Funding of Existing Groundwater Restoration. URI agrees, subject to the provisions contained herein, to fund groundwater
restoration at the Kingsville Dome mine site and Rosita mine site at the treatment rates (mgal/mo) specified in Appendix A, which comprises Appendices A-1 and A-2, both
of which are attached to and incorporated into this Agreement for all purposes. At the Kingsville Dome and Rosita mine sites URI's cost estimate for restoration expenses related to the Mines will be
reduced quarterly at a rate of $2.75 per thousand gallons of restoration water processed through reverse osmosis filtration equipment as specified in Appendices A-1 and A-2.
Unless otherwise approved by TDH and TCEQ, the restoration expenses shall be borne by a portion of the proceeds of the sale of uranium produced at another URI mine, the Vasquez Mine in Duval County,
Texas. In the event that URI is able to secure funds from sources other than production sales, other than funds provided by URI's investor group that are specifically designated for general and
administrative costs, and/or for the costs of resumption of production operations, URI will notify the TDH and TCEQ for a determination if these funds should be used to supplement financial security
with the TDH. 

        4.     Financial Security for Future Mining. Future mining at the Vasquez or Kingsville Dome site will be subject to acceptable
financial security as required by License L03653, Condition 25 and 25 TAC § 289.260(o). 

        5.     Additional Financial Security for Surface Remediation. URI will post acceptable additional financial security of $42,486
at the closing of this Agreement. 

        6.     Term of Agreement. This Agreement shall remain in force and effect from its effective date through August 31, 2007.
In the event both (i) URI fails to meet the Performance Criteria set forth in Appendix B, which comprises Appendices B-1 and B-2 and both of which are attached
hereto and incorporated herein for all purposes, for a specific quarterly period and (ii) satisfaction of such Appendix B Performance Criteria is not waived by the Agencies, the Agencies
may terminate the Agreement with 10 days notice to URI. If the Agencies terminate the Agreement, URI shall notify USF&G of such action. 

        7.     Force Majeure. URI shall not be deemed as failing to meet the Performance Criteria for a specific month due to any Act of
God, war, strike, riot, electrical outage, accident, fire, explosion, flood, blockade, governmental action or other catastrophe hereafter "force majeure," beyond URI's reasonable-control. In the event
of such force majeure, URI shall notify the Agencies of the event within 24 hours. Should such force majeure prevent or reduce groundwater restoration activities for the subsequent month, then
the Agencies may terminate the Agreement with 10 days notice to URI. 

        8.     Record Keeping. URI shall include a summary of reverse osmosis unit operating data including the amount of gallons
processed during a month in URI's quarterly performance reports to the Agencies. 

        URI
shall maintain and make available to the Agencies upon request, records of its groundwater restoration activities at the Mines. These records shall include: 1) accurate and
legible maps of well fields and well locations; and 2) accurate and up to date well completion and maintenance information. 

3

 

        9.     Progress Reports. URI shall provide a quarterly groundwater restoration progress report in accordance with
Appendix B to the Agencies no later than the 10th working day following the end of the calendar quarter. Such report will include an estimate of the remaining restoration required at the Mines. 

        10.   Surety Not an Owner or Operator. USF&G shall not be deemed an "owner" or "operator" of the Mines by virtue of execution
and delivery of and performance of its obligations under this Agreement. The parties' execution and delivery of this Agreement is not intended to make USF&G an "owner" or "operator." USF&G's role as
Surety will not in any way make it responsible for any operation of the Mines, nor will it own any part of the Mines. 

        11.   Agencies not an Owner or Operator. Neither TCEQ nor TDH shall be deemed an "owner" or "operator" of the Mines by virtue
of execution and/or delivery of and/or performance of either of the Agencies' obligations under this Agreement. The parties' execution and delivery of this Agreement is not intended to make TCEQ or
TDH an "owner" or "operator." TCEQ's or TDH's role in approving bond reductions will not in any way make either responsible for any operation of the Mines, nor will either of the Agencies own any part
of the Mines. 

        12.   Reservation of Defenses. USF&G's execution, delivery and performance under this Agreement shall not constitute, nor be
deemed to constitute, an admission of liability or a waiver of any claims or defenses which USF&G may assert or have against URI, Inc., any indemnitors, or against claims made against USF&G
under the Bond. The Agencies' execution, delivery or performance under this Agreement shall not constitute, nor be deemed to constitute, an admission of liability or waiver of any claims or defenses
which the Agencies may assert or have against URI, Inc. relative to the Mines, or USF&G. 

        13.   Bankruptcy of URI.

        13.1 It
is the express desire, intent, and agreement of the parties (TCEQ/TDH, URI and USF&G) that in the event URI shall become a Debtor in a bankruptcy proceeding (by
virtue of either the commencement of a voluntary or an involuntary petition) the rights of TCEQ/TDH and USF&G shall remain as unaffected as possible with respect to their mutual obligations under
these Bonds. Accordingly, as a material element of this Agreement, the parties expressly agree and covenant as follows: 

        13.2 URI
will enter into a Stipulation satisfactory to TCEQ/TDH and USF&G setting forth sufficient facts to demonstrate its acknowledgment that the parties would not have
entered into this Agreement absent such stipulation. The Stipulation shall further recite that, should URI become a Debtor in a Chapter 11 bankruptcy proceeding, it shall elect at the earliest of
(1) sixty (60) days from the Petition date or (2) thirty (30) days from the entry of the Order for Relief in the instance where an involuntary petition is commenced to  assume or
reject this Agreement as an executory contract.
 

        13.3 URI
and USF&G further agree that they shall take no action directly or indirectly to prevent the Bankruptcy Court from ordering URI to make such an accelerated election
regarding assumption or rejection of this Agreement in accordance with the time frame set forth above in paragraph 13.2. 

        13.4 In
the event URI elects to assume this executory contract, URI shall cure any pending defaults within 30 days of
the date it makes said election to assume (irrespective of the date of the entry of the Order approving assumption). In the event the Bonds are called, USF&G shall be entitled to a full credit against
the face amount of the Bonds for any partial payments distributed previously to URI in accordance with this Agreement. 

        13.5 In
the event URI elects to reject this executory contract, the parties agree that each will have whatever rights and
obligations it may have under this Agreement, the Bonds, and applicable law. 

4

 

        13.6 All
parties further acknowledge that the obligation of USF&G under these Bonds constitutes an independent obligation of USF&G as a surety in favor of TCEQ/TDH. URI
further covenants that in its legal opinion, should URI become a debtor in a bankruptcy proceeding, that these Bonds constitute independent obligations of USF&G and would not constitute assets of
URI's bankruptcy estate. URI further covenants that it shall take no action either directly or indirectly to controvert any position taken in the Bankruptcy Court by TCEQ/TDH that these Bonds are not
property of URI's bankruptcy estate. 

        13.7 URI
and USF&G acknowledge that there have been extensive confidential settlement communications, privileged under Federal Rule of Evidence 408, leading up to the
execution of this Agreement. URI, USF&G, and TCEQ/TDH further covenant that they shall never seek to introduce evidence of any prior negotiations that led up to this Agreement (by way of example but
not by limitation, introduction of previous drafts of this settlement Agreement as parole evidence). 

        13.8 In
the event of the bankruptcy of URI, the parties to this Agreement stipulate that the groundwater restoration equipment located at the Mines may continue to be used
for groundwater restoration activities until the groundwater restoration is completed. 

        14.   Notices. Any notices required or authorized to be given by this Agreement shall be in written form. Any notices required
or authorized to be given by this Agreement must be sent by: (a) registered or certified delivery mail, postage prepaid and return receipt requested, addressed to the proper party at the
following address or such address as the party shall have designated to the other parties in accordance with this Section; or (b) personal delivery. Mailed notice shall be effective on the

 B-1. Kingsville Dome Mine Site  

        I.     QUANTITY PERFORMANCE. Over any quarter covered by this Agreement, URI shall perform at a rate of at least 80% of the
instantaneous design rate for the installed equipment at Kingsville Dome. The rate at which water is treated is calculated by adding the waste disposal well flow to the RO feed flow and subtracting
the RO brine: 

	 	 	WDW 248 maximum average restoration flow capacity: 150 gal/min
 RO feed rate, design maximum: 585

Less RO brine contribution to WDW 248 flow: 146	 	 

[WDW
max + RO max—brine amount = maximum water heated: 589 gal/min] 

Therefore,
the calculated minimum rate per month is: 

589
gal/min × 1440 min/day × 30 days/month) × .80 = 20.4 million gallons per
month. 

        II.    QUALITY PERFORMANCE. Quality performance shall be assessed on a PAA by PAA basis using groundwater analysis to gauge
restoration progress. To allow the state staffs to evaluate restoration progress in terms of improvements in water quality, URI shall do the following: 

	a.
	Collect
water quality data at least once every two weeks from each extractor well in the areas currently under active restoration; data shall at a minimum include Conductivity, (or
TDS), uranium (as U3O8), Ca, pH, and SO4.

	b.
	At
least one time per quarter, at or near the beginning of the 2nd month of the quarter, collect water quality data as described above from all production area baseline wells in areas
previously considered restored. In addition, other wells, as selected by the Commission, shall be sampled for Radium-226.

	c.
	Submit
water quality sampling data in both tabular and graphic form to facilitate comparison to past restoration progress reports.

	d.
	Submit
restoration water quality progress reports monthly with the 3rd report in any quarter to include data from wells in areas previously considered restored. 

        Determination
of final restoration shall be done in accordance with standard state procedures, as found in 30 TAC § 331.107. Before final restoration is
confirmed, URI shall obtain stability samples from all production area baseline wells and analyze for those parameters listed in the restoration table.

brine: 

	 	 	WDW 250 maximum average capacity: 150 gal/min

Less RO brine contribution to WDW 250 flow: 146	 	 

[WDW
max + RO max—brine amount = maximum water treated: 589 gal/min] 

Therefore,
the calculated minimum rate per month is: 

589
gal/min × 1440 min/day × 30 days/month) × .80 = 20.4 million gallons per
month. 

        II.    QUALITY PERFORMANCE. Quality performance shall be assessed on a PAA by PAA basis using groundwater analysis to gauge
restoration progress. To allow the state staffs to evaluate restoration progress in terms of improvements in water quality, URI shall do the following:

	Submit
water quality sampling data in both tabular and graphic form to facilitate comparison to past restoration progress reports.

	d.
	Submit
restoration water quality progress reports monthly with the 3rd report in any quarter to include data from wells in areas previously considered restored. 

        Determination
of final restoration shall be done in accordance with standard slate procedures, as found in 30 TAC § 331.107. Before final restoration is
confirmed, URI shall obtain stability samples from all production area baseline wells and analyze for those parameters listed in the restoration table.

Interest") shall forthwith cease to be payable to the Noteholder on the relevant record date by virtue of his having been such Noteholder, and such Defaulted Interest shall be

        (1)   The
Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the
close of business on a special record date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of
Defaulted Interest proposed to be paid on each Note and the date of the proposed payment (which shall be not less than twenty-five (25) days after the receipt by the Trustee of such
notice, unless the Trustee shall consent to an earlier date), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount to be paid in respect of
such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the
benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a special record date for the payment of such Defaulted Interest which shall be

Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange or automated
quotation system on which the Notes may be listed or designated for issuance, and upon such notice as may be required by such exchange or automated quotation system, if, after notice given by the
Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

the manual or facsimile signature of its Chairman of the Board, Chief Executive Officer, President or any Vice President (whether or not designated by a number or numbers or word or words added before
or after the title "Vice President"). Only such Notes as shall bear thereon a certificate of authentication substantially in the form set forth on the
form of Note attached as Exhibit A hereto, manually executed by the Trustee (or an authenticating agent appointed by the Trustee as provided by Section 17.11), shall be entitled to the
benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by the Trustee (or such an authenticating agent) upon any Note executed by the Company shall be conclusive
evidence that the Note so authenticated has been duly authenticated and delivered hereunder and that the holder is entitled to the benefits of this Indenture. 

        In
case any officer of the Company who shall have signed any of the Notes shall cease to be such officer before the Notes so signed shall have been authenticated and delivered by the
Trustee, or disposed of by the Company, such Notes nevertheless may be authenticated and delivered or disposed of as though the person who signed such Notes had not ceased to be such officer of the
Company, and any Note may be signed on behalf of the Company by such persons as, at the actual date of the execution of such Note, shall be the proper officers of the Company, although at the date of
the execution of this Indenture any such person was not such an officer.

the Company nor the Trustee nor any Note Registrar shall be required to exchange or register a transfer of (a) any Notes or portions thereof surrendered for conversion
pursuant to Article 16 or (b) any Notes or portions thereof tendered for redemption (and not withdrawn) pursuant to Section 3.05.

any other provision in this Indenture, no Global Note may be exchanged in whole or in part for Notes registered, and no transfer of a Global Note in
whole or in part may be registered, in the name of any Person other than the Depositary or a nominee thereof unless (A) the Depositary (i) has notified the Company that it is unwilling

registered under the Exchange Act, (B) an Event of Default has occurred and is continuing or (C) the Company, in its sole discretion, notifies the Trustee in writing that it no longer

exchanged pursuant to clause (C) above may be exchanged in whole or from time to time in part as directed by the Company. Any Note issued in exchange for a Global Note or any portion thereof

denominations as the Depositary shall designate and shall bear any legends required hereunder. Any Global Note to be exchanged in whole shall be surrendered by the Depositary to the Trustee, as Note
Registrar. With regard to any Global Note to be exchanged in part, either such Global Note shall be so surrendered for exchange or, if the Trustee is acting as Custodian for the Depositary or its
nominee with respect to such Global Note, the principal amount thereof shall be reduced, by an amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the
records of the Trustee. Upon any such surrender or adjustment, the Trustee shall

and make available for delivery the Note issuable on such exchange to or upon the written order of the Depositary or an authorized representative thereof.

of certificated Notes in definitive, fully registered form, without interest coupons.

any members of, or participants in, the Depositary ("Agent Members") nor any other Persons on whose behalf Agent
Members may act shall have any rights under this Indenture with respect to any Global Note registered in the name of the Depositary or any nominee thereof, and the Depositary or such nominee, as the
case may be, may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and holder of such Global Note for all purposes whatsoever. Notwithstanding
the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished
by the Depositary or such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other Person on whose behalf an Agent Member may act, the operation of customary
practices of such Persons governing the exercise of the rights of a holder of any Note. 

        (vi)  At
such time as all interests in a Global Note have been redeemed, converted, canceled or exchanged for Notes in certificated form, such Global Note shall, upon receipt
thereof, be canceled by the Trustee in accordance with standing procedures and instructions existing between the Depositary and the Custodian. At any time prior to such cancellation, if any interest
in a Global Note is redeemed, converted, canceled or exchanged for Notes in certificated form, the principal amount of such Global Note shall, in accordance with the standing procedures and
instructions existing between the Depositary
and the Custodian, be appropriately reduced, and an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction. 

        (c)   Every
Note that bears or is required under this Section 2.05(c) to bear the legend set forth in this Section 2.05(c) (together with any Common Stock issued
upon conversion of the Notes and required to bear the legend set forth in Section 2.05(c), collectively, the "Restricted Securities") shall be
subject to the restrictions on transfer set forth in this Section 2.05(c) (including those set forth in the legend below) unless such restrictions on transfer shall be waived by written consent
of the Company, and the holder of each such Restricted Security, by such Note holder's acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in Section 2.05(c)
and 2.05(d), the term "transfer" encompasses any sale, pledge, loan, transfer or other disposition whatsoever of any Restricted Security or any interest
therein. 

        Until
the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision), any certificate evidencing such
Note (and all securities issued in exchange therefor or substitution thereof, other than Common Stock, if any, issued upon conversion thereof, which shall bear the legend set forth in
Section 2.05(c), if applicable) shall bear a legend in substantially the following form, unless such Note has been sold pursuant to a registration statement that has been declared effective
under the Securities Act (and which continues to be effective at the time of such transfer) or sold pursuant to Rule 144 under the Securities Act or any similar provision then in force, or
unless otherwise agreed by the Company in writing, with written notice thereof to the Trustee: 

THE
NOTE EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY STATE
SECURITIES LAWS AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT IT IS A
"QUALIFIED INSTITUTIONAL  

11

 

 BUYER" (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT); (2) AGREES THAT IT WILL NOT, PRIOR TO EXPIRATION OF THE HOLDING PERIOD APPLICABLE TO SALES OF THIS NOTE UNDER
RULE 144(K) UNDER THE SECURITIES ACT (OR ANY SUCCESSOR PROVISION), RESELL OR OTHERWISE TRANSFER THIS NOTE OR THE COMMON STOCK ISSUABLE UPON CONVERSION OF THIS NOTE EXCEPT (A) TO
INTERMUNE, INC. OR ANY SUBSIDIARY THEREOF, (B) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) PURSUANT TO THE EXEMPTION FROM
REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE) OR (D) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT (AND WHICH
CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH TRANSFER); (3) PRIOR TO SUCH TRANSFER (OTHER THAN A TRANSFER PURSUANT TO CLAUSE 2(D) ABOVE), IT WILL FURNISH TO THE BANK OF NEW YORK, AS TRUSTEE
(OR A SUCCESSOR TRUSTEE, AS APPLICABLE), SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS THE TRUSTEE MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN
EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT; AND (4) AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS NOTE IS TRANSFERRED A
NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. IN CONNECTION WITH ANY TRANSFER OF THIS NOTE PRIOR TO THE EXPIRATION OF THE HOLDING PERIOD APPLICABLE TO SALES OF THIS NOTE UNDER RULE 144(k) UNDER
THE SECURITIES ACT (OR ANY SUCCESSOR PROVISION), THE HOLDER MUST CHECK THE APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER OF SUCH TRANSFER AND SUBMIT THIS CERTIFICATE TO THE
BANK OF NEW YORK, AS TRUSTEE (OR A SUCCESSOR TRUSTEE, AS APPLICABLE). THIS LEGEND WILL BE REMOVED UPON THE EARLIER OF THE TRANSFER OF THIS NOTE PURSUANT TO CLAUSE 2(D) ABOVE OR UPON ANY TRANSFER OF
THIS NOTE UNDER RULE 144 UNDER THE SECURITIES ACT (OR ANY SUCCESSOR PROVISION). THE INDENTURE CONTAINS A PROVISION REQUIRING THE TRUSTEE TO REFUSE TO REGISTER ANY TRANSFER OF THIS NOTE IN VIOLATION OF
THE FOREGOING RESTRICTION. 

        Any
Note (or security issued in exchange or substitution therefor) as to which such restrictions on transfer shall have expired in accordance with their terms or as to conditions for
removal of the foregoing legend set forth therein have been satisfied may, upon surrender of such Note for exchange to the Note Registrar in accordance with the provisions of this Section 2.05,
be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the restrictive legend required by this Section 2.05(c). If the Restricted Security
surrendered for exchange is represented by a Global Note bearing the legend set forth in this Section 2.05(c), the principal amount of the legended Global Note shall be reduced by the
appropriate principal amount and the principal amount of a Global Note without the legend set forth in this Section 2.05(c) shall be increased by an equal principal amount. If a Global Note
without the legend set forth in this Section 2.05(c) is not then outstanding,
the Company shall execute and the Trustee shall authenticate and deliver an unlegended Global Note to the Depositary. 

        (d)   Until
the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision), any stock
certificate representing Common Stock issued upon conversion of any Note shall bear a legend in substantially the following form, unless such Common Stock has been sold pursuant to a registration
statement that has been declared effective under the Securities Act (and which continues to be effective at the time of such transfer) or pursuant to Rule 144 under the Securities Act or any
similar provision then in force, or such Common Stock has 

12

 

been
issued upon conversion of Notes that have been transferred pursuant to a registration statement that has been declared effective under the Securities Act or pursuant to Rule 144 under the
Securities Act or any similar provision then in force, or unless otherwise agreed by the Company in writing with written notice thereof to the transfer agent: 

THE
COMMON STOCK EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY
STATE SECURITIES LAWS AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. THE HOLDER HEREOF AGREES THAT, UNTIL THE EXPIRATION OF THE HOLDING PERIOD APPLICABLE
TO SALES OF THE COMMON STOCK EVIDENCED HEREBY UNDER RULE 144(k) UNDER THE SECURITIES ACT (OR ANY SUCCESSOR PROVISION), (1) IT WILL NOT RESELL OR OTHERWISE TRANSFER THE COMMON STOCK EVIDENCED
HEREBY EXCEPT (A) TO INTERMUNE, INC. OR ANY SUBSIDIARY THEREOF, (B) TO A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A
UNDER THE SECURITIES ACT) IN COMPLIANCE WITH RULE 144A, (C) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE) OR (D) PURSUANT TO A
REGISTRATION STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT (AND WHICH CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH TRANSFER); (2) PRIOR TO SUCH TRANSFER (OTHER THAN A
TRANSFER PURSUANT TO CLAUSE 1(D) ABOVE), IT WILL FURNISH TO MELLON INVESTOR SERVICES, AS TRANSFER AGENT (OR A SUCCESSOR TRANSFER AGENT, AS APPLICABLE), SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER
INFORMATION AS SUCH TRANSFER AGENT MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS
OF THE SECURITIES ACT AND (3) IT WILL DELIVER TO EACH PERSON TO WHOM THE COMMON STOCK EVIDENCED HEREBY IS TRANSFERRED (OTHER THAN A TRANSFER PURSUANT TO CLAUSE 1(D) ABOVE) A NOTICE
SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. THIS LEGEND WILL BE REMOVED UPON THE EARLIER OF THE TRANSFER OF THE COMMON STOCK EVIDENCED HEREBY PURSUANT TO CLAUSE 1(D) ABOVE OR UPON ANY TRANSFER OF THE
COMMON STOCK EVIDENCED HEREBY AFTER THE EXPIRATION OF THE HOLDING PERIOD APPLICABLE TO SALES OF THE SECURITY EVIDENCED HEREBY UNDER RULE 144(k) UNDER THE SECURITIES ACT (OR ANY SUCCESSOR PROVISION). 

        Any
such Common Stock as to which such restrictions on transfer shall have expired in accordance with their terms or as to which the conditions for removal of the foregoing legend set
forth therein have been satisfied may, upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of the transfer agent for the Common
Stock, be exchanged for a new certificate or certificates for a like number of shares of Common Stock, which shall not bear the restrictive legend required by this Section 2.05(d). 

        (e)   Any
Note or Common Stock issued upon the conversion of a Note that, prior to the expiration of the holding period applicable to sales thereof under Rule 144(k)
under the Securities Act (or any successor provision), is purchased or owned by the Company or any Affiliate thereof may not be resold by the Company or such Affiliate unless registered under the
Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction which results in such Notes or Common Stock, as the case may be, no longer
being "Restricted Securities" (as defined under Rule 144). 

13

 

        (f)    The
Trustee shall have no responsibility or obligation to any Agent Members or any other Person with respect to the accuracy of the books or records, or the acts or
omissions, of the Depositary or its nominee or of any participant or member thereof, with respect to any ownership interest in the Notes or with respect to the delivery to any Agent Member or other
Person (other than the Depositary) of any notice (including any notice of redemption) or the payment of any amount, under or with respect to such Notes. All notices and communications to be given to
the Noteholders and all payments to be made to Noteholders under the Notes shall be given or made only to or upon the order of the registered Noteholders (which shall be the Depositary or its nominee
in the case of a Global Note). The rights of beneficial owners in any Global Note shall be exercised only through the Depositary subject to the customary procedures of the Depositary. The Trustee may
rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its Agent Members. 

        The
Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with
respect to any transfer of any interest in any Note (including any transfers between or among Agent Members in any Global Indenture) other than to require delivery of such certificates and other
documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to
form with the express requirements hereof. 

        Section 2.06.    Mutilated, Destroyed, Lost or Stolen Notes.    In case any Note shall become mutilated or be
destroyed, lost or stolen, the Company in its discretion may execute, and upon its written request the Trustee or an authenticating agent appointed by the Trustee shall authenticate and make available
for delivery, a new Note, bearing a number not contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or
stolen. In every case, the applicant for a substituted Note shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required
by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, the applicant shall also
furnish to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof. 

        Following
receipt by the Trustee or such authenticating agent, as the case may be, of satisfactory security or indemnity and evidence, as described in the preceding paragraph, the
Trustee or such authenticating agent may authenticate any such substituted Note and make available for delivery such Note. Upon the issuance of any substituted Note, the Company may require the
payment by the holder of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith. In case any Note
which has matured or is about to mature or has been tendered for redemption upon a Designated Event (and not withdrawn) or is to be converted into Common Stock shall become mutilated or be destroyed,
lost or stolen, the Company may, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender thereof except in the case
of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or
indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or in connection with such substitution, and, in every case of destruction, loss
or theft, the applicant shall also furnish to the Company, the Trustee and, if applicable, any paying agent or conversion agent evidence to their satisfaction of the destruction, loss or theft of such
Note and of the ownership thereof. 

        Every
substitute Note issued pursuant to the provisions of this Section 2.06 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional
contractual obligation of the 

14

 

Company,
whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set forth in) this
Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that the
foregoing provisions are exclusive with respect to the replacement or payment or conversion or redemption of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or
remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment or conversion or redemption of negotiable instruments or other
securities without their surrender. 

        Section 2.07.    Temporary Notes.    Pending the preparation of Notes in certificated form, the Company may
execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon the written request of the Company, authenticate and deliver temporary Notes (printed or lithographed).
Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of the Notes in certificated form, but with such omissions, insertions and variations as may be
appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be
executed by the Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Notes in
certificated form. Without unreasonable delay, the Company will execute and deliver to the Trustee or such authenticating agent Notes in certificated form and thereupon any or all temporary Notes may
be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 6.02 and the Trustee or such authenticating agent shall authenticate and make
available for delivery in exchange for such temporary Notes an equal aggregate principal amount of Notes in certificated form. Such exchange shall be made by the Company at its own expense and without
any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Notes in certificated
form authenticated and delivered hereunder. 

        Section 2.08.    Cancellation of Notes.    All Notes surrendered for the purpose of payment, redemption,
conversion, exchange or registration of transfer shall, if surrendered to the Company or any paying agent or any Note Registrar or any conversion agent, be surrendered to the Trustee and promptly
canceled by it, or, if surrendered to the Trustee, shall be promptly canceled by it, and no Notes shall be issued in lieu thereof except as expressly permitted by any of the provisions of this
Indenture. The Trustee shall dispose of such canceled Notes in accordance with its customary procedures. If the Company shall acquire any of the Notes, such acquisition shall not operate as a
redemption, or satisfaction of the indebtedness represented by such Notes unless and until the same are delivered to the Trustee for cancellation. 

        Section 2.09.    CUSIP Numbers.    The Company in issuing the Notes may use
"CUSIP" numbers (if then generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices
of redemption as a convenience to Noteholders; provided that any such notice may state that no representation is made as to the correctness of such
numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such
redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the "CUSIP"
numbers. 

        Section 2.10.    Additional Notes.    The Company may, without the consent of the holders, issue Additional
Notes (the "Additional Notes") under this Indenture with the same terms and with the same CUSIP numbers as the Notes offered hereby in an unlimited
aggregate principal amount, provided that such Additional Notes must be part of the same issue as the notes offered hereby for United States federal income tax purposes. 

15

   
        Section 2.11.    Ranking.    The Notes constitute a senior unsecured general obligation of the Company,
ranking
equally with other existing and future senior unsecured and unsubordinated Indebtedness of the Company and ranking senior in right of payment to the Company's 5.75% convertible subordinated notes and
any future Indebtedness of the Company that is expressly made subordinate to the Notes by the terms of such Indebtedness.

REDEMPTION OF NOTES  

        Section 3.01.    Reserved.    

        Section 3.02.    Reserved.    

        Section 3.03.    Reserved.    

        Section 3.04.    Reserved.    

        Section 3.05.    Redemption At Option of Holders Upon a Designated Event.    

        (a)   If
there shall occur a Designated Event at any time prior to maturity of the Notes, then each Noteholder shall have the right, at such holder's option, to require the
Company to redeem for cash such holder's Notes, in whole or any portion thereof that is a multiple of $1,000 principal amount, on the date (the "Designated Event Redemption
Date") that is thirty (30) days after the date of the Designated Event Notice (as defined in Section 3.05(b)) of such Designated Event (or, if such 30th day is
not a Business Day, the next succeeding Business Day) at a redemption price equal to 100% of the principal amount thereof, plus accrued interest and Liquidated Damages, if any, to, but excluding, the
Designated Event Redemption Date (the "Designated Event Redemption Price"). Such redemption pursuant to this Section 3.05 shall be made at the
option of the Noteholder, upon: 

        (i)    delivery
to the Trustee (or other paying agent appointed by the Company) by a Noteholder of a duly completed form entitled "Option to Elect Repayment Upon A Designated
Event" (the "Redemption Notice") in the form set forth on the reverse of the Note during the period beginning at any time from the opening of business
on the date the Designated Event Notice is mailed until the close of business on the Designated Event Redemption Date; and 

        (ii)   delivery
or book-entry transfer of the Note or Notes to the Trustee (or other paying agent appointed by the Company) at any time after delivery of the
Designated Event Notice (together with all necessary endorsements) at the Corporate Trust Office of the Trustee (or other paying agent appointed by the Company) in the Borough of Manhattan, The City
of New York, as provided in Section 6.02, such delivery being a condition to receipt by the holder of the redemption price therefor; provided
that such redemption price shall be so paid pursuant to this Section 3.05 only if the Note so delivered to the Trustee (or other paying agent appointed by the Company) shall conform in all
respects to the description thereof in the related Redemption Notice. 

        The
Company shall redeem, pursuant to this Section 3.05, a portion of a Note, if the principal amount of such portion is $1,000 or a whole multiple of $1,000. Provisions of this
Indenture that apply to the redemption of all of a Note also apply to the redemption of such portion of such Note. Upon presentation of any Note redeemed in part only, the Company shall execute and,
upon the Company's written direction to the Trustee, the Trustee shall authenticate and make available for delivery to the holder thereof, at the expense of the Company, a new Note or Notes, of
authorized denominations, in aggregate principal amount equal to the unredeemed portion of the Notes presented. 

        Notwithstanding
anything herein to the contrary, any holder delivering to the Trustee (or other paying agent appointed by the Company) the Redemption Notice contemplated by this
Section 3.05 shall have the right to withdraw such Redemption Notice at any time prior to the close of business on 

16

 

the
Designated Event Redemption Date by delivery of a written notice of withdrawal to the Trustee (or other paying agent appointed by the Company) in accordance with Section 3.07. 

        The
Trustee (or other paying agent appointed by the Company) shall promptly notify the Company of the receipt by it of any Redemption Notice or written notice of withdrawal thereof. 

        (b)   On
or before the tenth day after the occurrence of any Designated Event of which it is aware, the Company at its written request (which must be received by the Trustee
at least five (5) Business Days prior to the date the Trustee is requested to give notice as described below, unless the Trustee shall agree in writing to a shorter period), or the Trustee, in
the name of and at the expense of the Company, shall mail or cause to be mailed to all holders of record on the date of the Designated Event a notice (the "Designated Event
Notice") of the occurrence of such Designated Event and of the redemption right at the option of the holders arising as a result thereof. Such notice shall be mailed by first
class mail. The notice, if mailed in the manner herein provided, shall be conclusively presumed to have been duly given, whether or not the holder receives such notice. If the Company shall give such
notice, the Company shall also deliver a copy of the Designated Event Notice to the Trustee at such time as it is mailed to Noteholders. Concurrently with the mailing of any Designated Event Notice,
the Company shall issue a press release announcing such Designated Event referred to in the Designated Event Notice, the form and content of which press release shall be determined by the Company in
its sole discretion. The failure to issue any such press release or any defect therein shall not affect the validity of the Designated Event Notice or any proceedings for the redemption of any Note
which any Noteholder may elect to have the Company redeem as provided in this Section 3.05. 

        Each
Designated Event Notice, subject to the conditions set forth in Section 3.06(a), shall specify the circumstances constituting the Designated Event, the Designated Event
Redemption Date, the price at which the Company shall be obligated to redeem Notes, that the holder must exercise the redemption right on or prior to the close of business on the Designated Event
Redemption Date (the "Designated Event Expiration Time"), that the holder shall have the right to withdraw any Notes surrendered prior to the Designated
Event Expiration Time, a description of the procedure which a Noteholder must follow to exercise such redemption right and to withdraw any surrendered Notes, the place or places where the holder is to
surrender such holder's Notes, the amount of interest and Liquidated Damages, if any, accrued on each Note to the Designated Event Redemption Date and the CUSIP number or numbers of the Notes (if then
generally in use). 

        No
failure of the Company to give the foregoing notices and no defect therein shall limit the Noteholders' redemption rights or affect the validity of the proceedings for the redemption
of the Notes pursuant to this Section 3.05. 

        (c)   In
the case of a reclassification, change, consolidation, merger, combination, sale or conveyance to which Section 16.06 applies, in which the Common Stock of the
Company is changed or exchanged as a result into the right to receive stock, securities or other property or assets (including cash), which includes shares of Common Stock of the Company or shares of
common stock of another Person that are, or upon issuance will be, traded on a United States national securities exchange or approved for trading on an established automated
over-the-counter trading market in the United States and such shares constitute at the time such change or exchange becomes effective in excess of 50% of the aggregate fair
market value of such stock, securities or other property or assets (including cash) (as determined by the Company, which determination shall be conclusive and binding), then the Person formed by such
consolidation or resulting from such merger or which acquires such assets, as the case may be, shall execute and deliver to the Trustee a supplemental indenture (accompanied by an Opinion of Counsel
that such supplemental indenture complies with this Indenture and the Trust Indenture Act as in force at the date of execution of such supplemental indenture) modifying the provisions of this
Indenture relating to the right of holders of the Notes to cause the Company to redeem the Notes following a Designated Event, including without limitation the applicable provisions of this
Section 3.05 

17

 

and
the definitions of Common Stock and Designated Event, as appropriate, as determined in good faith by the Company (which determination shall be conclusive and binding), to make such provisions
apply to such other Person if different from the Company and the common stock issued by such Person (in lieu of the Company and the Common Stock of the Company). 

        (d)   The
Company will comply with the provisions of Rule 13e-4 and any other tender offer rules under the Exchange Act to the extent then applicable in
connection with the redemption rights of the holders of Notes in the event of a Designated Event. 

        Section 3.06.    The Company's Right to Elect Manner of Redemption upon a Designated Event.    

        (a)   The
Securities to be redeemed with respect to any Designated Event Redemption Date pursuant to Section 3.05(a) may be redeemed at the election of the Company in
cash or shares of Common Stock, or if applicable, a parent corporation's common stock, or in any combination of cash and shares of Common Stock or such parent corporation's common stock, subject to
the conditions set forth in Section 3.06(b). The Company shall designate, in the Designated Event Notice delivered pursuant to Section 3.05(b), whether the Company will redeem the Notes
for cash or shares of Common Stock, or if applicable, a parent corporation's common stock, or if a combination thereof, the percentages of the Designated Event Redemption Price in respect of which it
will pay in cash or shares of Common Stock, or if applicable, a parent corporation's common stock, provided, however, that the Company will pay cash for
fractional interests in shares of Common Stock, or if applicable, a parent corporation's common stock. 

        For
purposes of determining the existence of potential fractional interests, all Securities subject to redemption by the Company held by a Holder shall be considered together (no matter
how many
separate certificates are to be presented). Each Holder whose Notes are redeemed pursuant to Section 3.05 shall receive the same percentage of cash or shares of Common Stock, or if applicable,
a parent corporation's common stock, in payment of the Designated Event Redemption Price for such Notes, except (i) as provided in this (a) with regard to the payment of cash in lieu of
fractional shares of Common Stock and (ii) in the event that the Company is unable to redeem the Notes of a Holder or Holders for shares of Common Stock because any necessary qualifications or
registrations of the shares of Common Stock under applicable securities laws cannot be obtained, the Company may redeem the Notes of such Holder or Holders for cash. The Company may not change its
election with respect to the consideration (or components or percentages of components thereof) to be paid once the Company has given its Designated Event Notice to Holders except in the event of a
failure to satisfy, prior to 5:00 p.m., New York City time, on the Business Day immediately preceding the Designated Event Redemption Date, any condition to the payment of the Designated Event
Redemption Price, in whole or in part, in shares of Common Stock or, if applicable, a parent corporation's common stock. 

        (b)   If
the Company elects to pay all or a portion of the Designated Event Redemption Price in respect of which a Designated Event Notice has been given in Common Stock, or
if applicable, a parent corporation's common stock, the number of shares of Common Stock, or if applicable, a parent corporation's common stock, to be issued shall be equal to (i) the portion
of the Designated Event Redemption Price to be paid in Common Stock, or if applicable, a parent corporation's common stock, divided by (ii) the Market Price of one share of Common Stock, or if
applicable, a parent corporation's common stock, subject to satisfaction of the conditions set forth in the second succeeding paragraph. 

        The
Company will not issue any fraction of a share of Common Stock in payment of the Designated Event Repurchase Price. Instead, the Company will make a cash payment (calculated to the
nearest cent) equal to such fraction multiplied by the Market Price of one share of Common Stock, or if applicable, a parent corporation's common stock. If a Holder elects to have more than one
Security purchased, the number of shares of Common Stock shall be based on the aggregate amount of Securities to be purchased. 

18

 

        The
Company's right to exercise its election to redeem the Notes through the issuance of shares of Common Stock, or if applicable, a parent corporation's common stock, shall be
conditioned upon: 

        (i)    the
registration of such shares of Common Stock, or if applicable, a parent corporation's common stock, under the Securities Act and the Exchange Act, in each case, if
required; 

        (ii)   any
qualification or registration of such shares of Common Stock, or if applicable, a parent corporation's common stock, under applicable state securities laws, if
necessary, or the availability of an exemption from such qualification and registration; 

        (iii)  listing
of the common stock on a United States national securities exchange or quotation thereof in an inter-dealer quotation system of any registered United States
national securities association. 

        (iv)  the
receipt by the Trustee of an Officers' Certificate stating (A): that the terms of the issuance of the shares of Common Stock, or if applicable, a parent
corporation's common stock, are in conformity with this Indenture; (B) that the shares of Common Stock, or if applicable, a parent corporation's common stock, to be issued in payment of the
Designated Event Redemption Price in respect of Notes have been duly authorized and, when issued and delivered pursuant to the terms of this Indenture in payment of the Designated Event Redemption
Price in respect of Notes, will be validly issued, fully paid, non-assessable and free from preemptive rights; (C) that the conditions in this clause (iv)(A) and (iv)(B)
above, the conditions in clauses (i) to (iii) above and the condition set forth in the second succeeding paragraph regarding issuance of a press release have been satisfied in all
material respects; and (D) the number of shares of Common Stock, or if applicable, a parent corporation's common stock, to be issued for each $1,000 Principal Amount of Notes and the Closing
Sale Price of a share of Common Stock on each Trading Day during the period commencing on the first Trading Day of the period during which the Market Price is calculated and ending on the Trading Day
immediately preceding the Designated Event Redemption Date; and 

        (v)   the
receipt by the Trustee of an Opinion of Counsel stating that: (A) the shares of Common Stock, or if applicable, a parent corporation's common stock, to be
issued by the Company in payment of the Designated Event Redemption Price in respect of the Notes have been duly authorized, and when issued and delivered pursuant to the terms of this Indenture in
payment of the Designated Event Redemption Price in respect of the Notes, will be validly issued, fully paid and non-assessable and, to such counsel's knowledge, free from preemptive
rights; and (B) the condition in clause (i) above has been satisfied in all material respects. 

        If
the foregoing conditions are not satisfied with respect to a Holder or Holders prior to 5:00 p.m., New York City time, on the Business Day immediately preceding the Designated
Event Redemption Date, and the Company has elected to redeem the Securities pursuant to this Section 3.06 through the issuance of shares of Common Stock, or if applicable, a parent
corporation's common stock, the Company shall pay the entire Designated Event Redemption Price of the Notes of such Holder or Holders in cash. Upon determination of the actual number of shares of
Common Stock, or if applicable, a parent corporation's common stock, to be issued upon redemption of the Notes, the Company shall be required to disseminate a press release through a public medium as
is customary for such a press release. 

        (c)   All
shares of Common Stock, or if applicable, a parent corporation's common stock, delivered upon redemption of the Notes shall be newly issued shares, shall be duly
authorized, validly issued, fully paid and nonassessable, and shall be free from preemptive rights and free of any lien or adverse claim. 

        (d)   If
a Holder of a redeemed Note is paid in shares of Common Stock, or if applicable, a parent corporation's common stock, the Company shall pay any documentary, stamp or
similar issue or 

19

 

transfer
tax due on such issue of Common Stock. However, the Holder shall pay any such tax which is due because the Holder requests the Common Stock, or if applicable, a parent corporation's common
stock, to be issued in a name other than the Holder's name. The Paying Agent may refuse to deliver the certificates representing the shares of Common Stock, or if applicable, a parent corporation's
common stock, being issued in a name other than the Holder's name until the Paying Agent receives a sum sufficient to pay any tax which will be due because the shares of Common Stock, or if
applicable, a parent corporation's common stock, are to be issued in a name other than the Holder's name. Nothing contained herein shall preclude any income tax withholding required by law or
regulations. 

        Section 3.07.    Effect of Redemption Notice.    

        (a)   Upon
receipt by the Trustee (or other paying agent appointed by the Company) of the Redemption Notice specified in Section 3.05(a), the holder of the Note in
respect of which such Redemption Notice was given shall (unless such Redemption Notice is validly withdrawn) thereafter be entitled to receive solely the redemption price with respect to such Note.
Such redemption price shall be paid to such Noteholder, subject to receipt of funds and/or Notes by the Trustee (or other paying agent appointed by the Company), promptly following the later of
(x) the Designated Event Redemption Date with respect to such Note (provided the holder has satisfied the conditions in Section 3.05) and (y) the time of delivery of such Note to
the Trustee (or other paying agent appointed by the Company) by the holder thereof in the manner required by Section 3.05. Notes in respect of which a Redemption Notice has been given by the
holder thereof may not be converted pursuant to Article 16 hereof on or after the date of the delivery of such Redemption Notice unless such Redemption Notice has first been validly withdrawn. 

        (b)   A
Redemption Notice may be withdrawn by means of a written notice of withdrawal delivered to the office of the Trustee (or other paying agent appointed by the Company)
in accordance with the Redemption Notice at any time prior to the close of business on the Designated Event Redemption Date, specifying: 

        (i)    the
certificate number, if any, of the Note in respect of which such notice of withdrawal is being submitted, or the appropriate Depositary information if the Note in
respect of which such notice of withdrawal is being submitted is represented by a Global Note, 

        (ii)   the
principal amount of the Note with respect to which such notice of withdrawal is being submitted, and 

        (iii)  the
principal amount, if any, of such Note which remains subject to the original Redemption Notice and which has been or will be delivered for redemption by the
Company. 

        Section 3.08.    Deposit of Redemption Price.    

        (a)   Prior
to 10:00 a.m. (New York City Time) on the Business Day following the Designated Event Redemption Date, the Company shall deposit with the Trustee (or other
paying agent appointed by the Company; or, if the Company or a Subsidiary or an Affiliate of either of them is acting as the paying agent, shall segregate and hold in trust as provided in
Section 6.04) an amount of cash (in immediately available funds if deposited on such Business Day), sufficient to pay the aggregate redemption price of all the Notes or portions thereof that
are to be redeemed as of the Designated Event Redemption Date. 

        (b)   If
the Trustee or other paying agent appointed by the Company, or the Company or a Subsidiary or Affiliate of either of them, if such entity is acting as the paying
agent, holds cash sufficient to pay the aggregate redemption price of all the Notes, or portions thereof, that are to be redeemed as of the Designated Event Redemption Date, on or after the Designated
Event Redemption Date (i) the Notes will cease to be outstanding, (ii) interest on the Notes will cease to accrue, and (iii) all other rights of the holders of such Notes will
terminate, whether or not book-entry transfer of 

20

 

the
Notes has been made or the Notes have been delivered to the Trustee or paying agent, other than the right to receive the redemption price upon delivery of the Notes. 

        Section 3.09.    Repayment to the Company.    The Trustee (or other paying agent appointed by the Company)
shall return to the Company any cash that remains unclaimed as provided in Section 14.04. 

        Section 3.10.    Redemption Upon Changes In Withholding Taxes.    The Notes may be redeemed (the  "Withholding Tax Redemption"), as a whole
but not in part, at the election of the Company, upon not less than 30 nor more than 60 days notice
(which notice shall be irrevocable), at a redemption price equal to the Principal Amount plus accrued and unpaid interest to, but excluding, the redemption date and Additional Amounts, if any, if the
Company, including as a result of a merger or sale of assets where a parent Person is organized outside of the United States, has become or will become obligated to pay Additional Amounts, on the next
date on which any amount would be payable with respect to such Notes, and such obligation cannot be avoided by the use of reasonable measures available to the Company; provided, however, that
(a) no such notice of redemption may be given earlier than 60 days prior to the earliest date on which the Company would be obligated to pay such Additional Amounts, and (b) at
the time such notice of redemption is given, such obligation to pay such Additional Amounts remains in effect. Prior to the giving of any notice of redemption described in this paragraph, the Company
shall deliver to the Trustee (i) a certificate of the Company, signed by two directors of the
Company, stating that the obligation to pay Additional Amounts cannot be avoided by the Company taking reasonable measures available to it and (ii) an Opinion of Counsel of recognized standing
to the effect that the Company has or will become obligated to pay Additional Amounts. 

        Notwithstanding
the foregoing, if the Company has given notice of a Withholding Tax Redemption as described in this Section 3.10 each Holder shall have the right to elect that
such Holder's Notes will not be subject to such Withholding Tax Redemption. If a Holder elects not to be subject to a Withholding Tax Redemption, the Company will not be required to pay any Additional
Amounts as provided in Section 6.12 below with respect to payments made on such Holder's Notes following the date of such Withholding Tax Redemption, and all subsequent payments on such
Holder's Notes will be subject to any tax required to be withheld or deducted. Holders must elect their option to avoid a Withholding Tax Redemption by written notice to the Trustee no later than the
15th day prior to the date of such Withholding Tax Redemption fixed by the Company stating: 

        (1)   the
name and address of the registered Holder of the Notes subject to such election: 

        (2)   the
certificate numbers and Principal Amount of such Notes; 

        (3)   that
the Holder elects to avoid the Withholding Tax Redemption and that the Holder will not be entitled to any Additional Amounts with respect to payments made on such
Holder's Notes following the date of such Withholding Tax Redemption.

PARTICULAR COVENANTS OF THE COMPANY  

        Section 6.01.    Payment of Principal, Premium and Interest.    The Company covenants and agrees that it will
duly and punctually pay or cause to be paid the principal of and premium, if any (including 

21

 

the
redemption price upon redemption pursuant to Article 3), and interest, on each of the Notes at the places, at the respective times and in the manner provided herein and in the Notes. 

        Section 6.02.    Maintenance of Office or Agency.    The Company will maintain an office or agency in the
Borough of Manhattan, The City of New York, where the Notes may be surrendered for registration of transfer or exchange or for presentation for payment or for conversion or redemption and where
notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the
location, of such office or agency not designated or appointed by the Trustee. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee
with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office. 

        The
Company may also from time to time designate co-registrars and one or more offices or agencies where the Notes may be presented or surrendered for any or all such
purposes and may from time to time rescind such designations. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any
such other office or agency. 

        The
Company hereby initially designates the Trustee as paying agent, Note Registrar, Custodian and conversion agent and the Corporate Trust Office shall be considered as one such office
or agency of the Company for each of the aforesaid purposes. 

        So
long as the Trustee is the Note Registrar, the Trustee agrees to mail, or cause to be mailed, the notices set forth in Section 9.10(a) and the third paragraph of
Section 9.11. If co-registrars have been appointed in accordance with this Section, the Trustee shall mail such notices only to the Company and the holders of Notes it can identify
from its records. 

        Section 6.03.    Appointments to Fill Vacancies in Trustee's Office.    The Company, whenever necessary to
avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 9.10, a Trustee, so that there shall at all times be a Trustee hereunder. 

        Section 6.04.    Provisions as to Paying Agent.    (a) If the Company shall appoint a paying agent other
than the Trustee, or if the Trustee shall appoint such a paying agent, the Company will cause such paying agent to execute and deliver to the Trustee an instrument in which such agent shall agree with
the Trustee, subject to the provisions of this Section 6.04: 

        (1)   that
it will hold all sums held by it as such agent for the payment of the principal of and premium, if any, or interest on the Notes (whether such sums have been paid
to it by the Company or by any other obligor on the Notes) in trust for the benefit of the holders of the Notes; 

        (2)   that
it will give the Trustee notice of any failure by the Company (or by any other obligor on the Notes) to make any payment of the principal of and premium, if any, or
interest on the Notes when the same shall be due and payable; and 

        (3)   that
at any time during the continuance of an Event of Default, upon request of the Trustee, it will forthwith pay to the Trustee all sums so held in trust. 

        The
Company shall, on or before each due date of the principal of, premium, if any, or interest on the Notes, deposit with the paying agent a sum (in funds which are immediately
available on the due date for such payment) sufficient to pay such principal, premium, if any, or interest, and (unless such paying agent is the Trustee) the Company will promptly notify the Trustee
of any failure to take such action; provided that if such deposit is made on the due date, such deposit shall be received by the paying agent by
10:00 a.m. New York City time, on such date. 

22

   
        (b)   If the Company shall act as its own paying agent, it will, on or before each due date of the principal of, premium, if any, or interest on the Notes, set aside,
segregate and hold in trust for the benefit of the holders of the Notes a sum sufficient to pay such principal, premium, if any, or interest so becoming due and will promptly notify the Trustee of any
failure to take such action and of any failure by the Company (or any other obligor under the Notes) to make any payment of the principal of, premium, if any, or interest on the Notes when the same
shall become due and payable. 

        (c)   Anything
in this Section 6.04 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction and discharge of this
Indenture, or for any other reason, pay or cause to be paid to the Trustee all sums held in trust by the Company or any paying agent hereunder as required by this Section 6.04, such sums to be
held by the Trustee upon the trusts herein contained and upon such payment by the Company or any paying agent to the Trustee, the Company or such paying agent shall be released from all further
liability with respect to such sums. 

        (d)   Anything
in this Section 6.04 to the contrary notwithstanding, the agreement to hold sums in trust as provided in this Section 6.04 is subject to Sections
14.03 and 14.04. 

        The
Trustee shall not be responsible for the actions of any other paying agents (including the Company if acting as its own paying agent) and shall have no control of any funds held by
such other paying agents. 

        Section 6.05.    Existence.    Subject to Article 13, the Company will do or cause to be done all things
necessary to preserve and keep in full force and effect its existence and rights (charter and statutory); provided that the Company shall not be
required to preserve any such right if the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is not
disadvantageous in any material respect to the Noteholders. 

        Section 6.06.    Maintenance of Properties.    The Company will cause all properties used or useful in the
conduct of its business or the business of any Significant Subsidiary to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and will cause to
be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Company may be necessary so that the business carried on in connection
therewith may be properly and advantageously conducted at all times; provided that nothing in this Section shall prevent the Company from discontinuing
the operation or maintenance of any of such properties if such discontinuance is, in the judgment of the Company, desirable in the conduct of its business or the business of any subsidiary and not
disadvantageous in any material respect to the Noteholders. 

        Section 6.07.    Payment of Taxes and Other Claims.    The Company will pay or discharge, or cause to be paid
or discharged, before the same may become delinquent, (i) all taxes, assessments and governmental charges levied or imposed upon the Company or any Significant Subsidiary or upon the income,
profits or property of the Company or any Significant Subsidiary, (ii) all claims for labor, materials and supplies which, if unpaid, might by law become a lien or charge upon the property of
the Company or any Significant Subsidiary and (iii) all stamp taxes and other duties, if any, which may be imposed by the United States or any political subdivision thereof or therein in
connection with the issuance, transfer, exchange, conversion or redemption of any Notes or with respect to this Indenture; provided that, in the case of
clauses (i) and (ii), the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim (A) if the failure to do so will
not, in the aggregate, have a material adverse impact on the Company, or (B) if the amount, applicability or validity is being contested in good faith by appropriate proceedings. 

        Section 6.08.    Rule 144A Information Requirement.    Within the period prior to the expiration of the
holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision), the Company covenants and agrees that it shall, during any period in which it
is 

23

 

not
subject to Section 13 or 15(d) under the Exchange Act, make available to any holder or beneficial holder of Notes or any Common Stock issued upon conversion thereof which continue to be
Restricted Securities in connection with any sale thereof and any prospective purchaser of Notes or such Common Stock designated by such holder or beneficial holder, the information required pursuant
to Rule 144A(d)(4) under the Securities Act upon the request of any holder or beneficial holder of the Notes or such Common Stock and it will take such further action as any holder or
beneficial holder of such Notes or such Common Stock may reasonably request, all to the extent required from time to time to enable such holder or beneficial holder to sell its Notes or Common Stock
without registration under the Securities Act within the limitation of the exemption provided by Rule 144A, as such Rule may be amended from time to time. Upon the request of any holder or any
beneficial holder of the Notes or such Common Stock, the Company will deliver to such holder a written statement as to whether it has complied with such requirements. 

        Section 6.09.    Stay, Extension and Usury Laws.    The Company covenants (to the extent that it may lawfully
do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other similar law which would
prohibit or forgive the Company from paying all or any portion of the principal of, premium, if any, or interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in
force, or which may affect the covenants or the performance of this Indenture and the Company (to the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law,
and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such
power as though no such law had been enacted. 

        Section 6.10.    Compliance Certificate.    The Company shall deliver to the Trustee, within one hundred twenty
(120) days after the end of each fiscal year of the Company, an Officers' Certificate signed by either the principal executive officer, principal financial officer or principal accounting
officer of the Company, stating whether or not to the best knowledge of the signers thereof the Company is in default in the performance and observance of any of the terms, provisions and conditions
of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and, if the Company shall be in default, specifying all such defaults and the nature and the
status thereof of which the signers may have knowledge. 

        The
Company will deliver to the Trustee, forthwith upon becoming aware of (i) any default in the performance or observance of any covenant, agreement or condition contained in
this Indenture, or (ii) any Event of Default, an Officers' Certificate specifying with particularity such default or Event of Default and further stating what action the Company has taken, is
taking or proposes to take with respect thereto. 

        Any
notice required to be given under this Section 6.10 shall be delivered to a Responsible Officer of the Trustee at its Corporate Trust Office. 

        Section 6.11.    Liquidated Damages Notice.    In the event that the Company is required to pay Liquidated
Damages to holders of Notes pursuant to the Registration Rights Agreement, the Company will provide written notice ("Liquidated Damages Notice") to the
Trustee of its obligation to pay Liquidated Damages no later than fifteen (15) days prior to the proposed payment date for the Liquidated Damages, and the Liquidated Damages Notice shall set
forth the amount of Liquidated Damages to be paid by the Company on such payment date. The Trustee shall not at any time be under any duty or responsibility to any holder of Notes to determine the
Liquidated Damages, or with respect to the nature, extent or calculation of the amount of Liquidated Damages when made, or with respect to the method employed in such calculation of the Liquidated
Damages. 

        Section 6.12.    Payment Of Additional Amounts.    All payments made by the Company under the Notes will be
made free and clear of and without withholding or deduction for or on account of any 

24

 

present
or future taxes, duties, levies, imposts, assessments or governmental charges of whatever nature imposed or levied by or on behalf of any taxing authority
("Taxes"), unless the Company is required to withhold or deduct Taxes by law or by the interpretation or administration thereof. In the event that the
Company is required to so withhold or deduct any amount for or on account of any Taxes from any payment made under the Notes, the Company will pay such additional amounts
("Additional Amounts") as may be necessary so that the net amount received by each Holder of Securities (including Additional Amounts) after such
withholding or deduction will equal the amount that such Holder would have received if such Taxes had not been required to be withheld or deducted; provided that no Additional Amounts will be payable
with respect to a payment made to a Holder of Securities to the extent: 

        (i)    that
any such Taxes would not have been so imposed but for the existence of any present or former connection between such Holder and the Taxing Authority imposing such
Taxes (other than the mere receipt of such payment, acquisition, ownership or disposition of such Notes or the exercise or enforcement of rights under such Notes or this Indenture); 

        (ii)   of
any estate, inheritance, gift, sales, transfer, or personal property Taxes imposed with respect to such Notes, except as otherwise provided herein; 

        (iii)  that
any such Taxes would not have been so imposed but for the presentation of such Notes (where presentation is required) for payment on a date more than
30 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for, whichever is later, except to the extent that the beneficiary or
Holder thereof would have been entitled to Additional Amounts had the Notes been presented for payment on any date during such 30-day period; 

        (iv)  that
such Holder would not be liable or subject to such withholding or deduction of Taxes but for the failure to make a valid declaration of non-residence
or other similar claim for exemption, if (x) the making of such declaration or claim is required or imposed by statute, treaty, regulation, ruling or administrative practice of the relevant
Taxing Authority as a precondition to an exemption from, or reduction in, the relevant Taxes, and (y) at least 60 days prior to the first payment date with respect to which the Company
shall apply this subclause (iv), the Company or the Guarantor shall have notified all Holders of Securities in writing that they shall be required to provide such declaration or claim; or 

        (v)   that
such Holder has elected to avoid a Withholding Tax Redemption pursuant to the last paragraph of Section 3.10 with respect to payments made subsequent to the
date of such Withholding Tax Redemption. 

        The
Company will also (i) make such withholding or deduction of Taxes and (ii) remit the full amount of Taxes so deducted or withheld to the relevant Taxing Authority in
accordance with all applicable laws. The Company will use its reasonable best efforts to obtain certified copies of tax receipts evidencing the payment of any Taxes so deducted or withheld from each
Taxing Authority imposing such Taxes. The Company, as the case may be, will, upon request, make available to the Holders of the Notes, within 60 days after the date the payment of any Taxes so
deducted or withheld is due pursuant to applicable law, certified copies of tax receipts evidencing such payment by the Company, notwithstanding the Company's efforts to obtain such receipts, the same
are not obtainable, other evidence of such payments by the Company. 

        In
the event that the Company is obligated to pay Additional Amounts with respect to any payment of principal, interest, redemption price or any other amount payable under or with
respect to the Notes, 30 days prior to the date such payment is due and payable, the Company, will deliver to the Trustee an Officer's Certificate stating the fact that such Additional Amounts
will also be payable, the 

25

 

amounts
so payable and such other information as is necessary to enable the Trustee to pay such Additional Amounts to the Holders on such payment date. 

        The
foregoing provisions shall survive any termination or discharge of this Indenture and shall apply mutatis mutandis to any jurisdiction in which any successor Person to the Company,
as the case may be, is organized or is engaged in business for tax purposes or any political subdivisions or taxing authority or agency thereof or therein. 

        In
addition, the Company will pay any stamp, issue, registration, documentary or other similar taxes and duties, including interest, penalties and Additional Amounts with respect
thereto, payable in connection with the conversion of redemption of the notes for stock or a combination of stock and cash that would not have been payable but for the fact that the stock is being
issued by a non-U.S. entity. 

        Whenever
in this Indenture or the Notes there is mentioned, in any context, the payment of principal, interest, redemption price or any other amount payable under or with respect to any
Notes, such mention shall be deemed to include mention of the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof. 

ARTICLE 7

        Section 7.01.    Noteholders' Lists.    The Company covenants and agrees that it will furnish or cause to be

times as the Trustee may request in writing, within thirty (30) days after receipt by the Company of any such request (or such lesser time as the Trustee may reasonably request in order to
enable it to timely provide any notice to be provided by it hereunder), a list in such form as the Trustee may reasonably require of the names and addresses of the holders of Notes as of a date not
more than fifteen (15) days (or such other date as the Trustee may reasonably request in order to so provide any such notices) prior to the time such information is furnished, except that no
such list need be furnished by the Company to the Trustee so long as the Trustee is acting as the sole Note Registrar. 

        Section 7.02.    Preservation And Disclosure Of Lists.    (a) The Trustee shall preserve, in as current
a form as is reasonably practicable, all information as to the names and addresses of the holders of Notes contained in the most recent list furnished to it as provided in Section 7.01 or
maintained by the Trustee in its capacity as Note Registrar or co-registrar in respect of the Notes, if so acting. The Trustee may destroy any list furnished to it as provided in
Section 7.01 upon receipt of a new list so furnished. 

        (b)   The
rights of Noteholders to communicate with other holders of Notes with respect to their rights under this Indenture or under the Notes, and the corresponding rights
and duties of the Trustee, shall be as provided by the Trust Indenture Act. 

        (c)   Every
Noteholder, by receiving and holding the same, agrees with the Company and the Trustee that neither the Company nor the Trustee nor any agent of either of them
shall be held accountable by reason of any disclosure of information as to names and addresses of holders of Notes made pursuant to the Trust Indenture Act. 

        Section 7.03.    Reports By Trustee.    (a) Within sixty (60) days after May 15 of each

applicable sections of the Trust Indenture Act the Trustee shall be under no duty or obligation to provide such reports. 

26

 

        (b)   A
copy of such report shall, at the time of such transmission to holders of Notes, be filed by the Trustee with each stock exchange and automated quotation system upon
which the Notes are listed or quoted and with the Company. The Company will promptly notify the Trustee in writing when the Notes are listed on any stock exchange or automated quotation system or
delisted therefrom. 

        Section 7.04.    Reports by Company.    The Company shall file with the Trustee (and the Commission if at any
time after the Indenture becomes qualified under the Trust Indenture Act), and transmit to holders of Notes, such information, documents and other reports and such summaries thereof, as may be
required pursuant to the Trust Indenture Act at the times and in the manner provided pursuant to such Act, whether or not the Notes are governed by such Act;  provided that any such information,
documents or reports required to be filed with the Commission pursuant to Section 13 or 15(d) of the Exchange
Act shall be made available to the Trustee within fifteen (15) days after the same is so required to be filed with the Commission. Delivery of such reports, information and documents to the
Trustee is for informational purposes only and the Trustee's receipt of such shall not constitute constructive notice of
any information contained therein or determinable from information contained therein, including the Company's compliance with any of its covenants hereunder (as to which the Trustee is entitled to
rely exclusively on an Officers' Certificates). 

ARTICLE 8

        (e)   failure
on the part of the Company duly to observe or perform any other of the covenants or agreements on the part of the Company in the Notes or in this Indenture
(other than a covenant or agreement a default in whose performance or whose breach is elsewhere in this Section 8.01 specifically dealt with) continued for a period of sixty (60) days
after the date on which written notice of such failure, requiring the Company to remedy the same, shall have been given to the Company by the Trustee, or the Company and a Responsible Officer of the
Trustee by the holders of at least twenty-five percent (25%) in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 10.04; or 

        (f)    the
Company shall commence a voluntary case or other proceeding seeking liquidation, reorganization or other relief with respect to the Company or its debts under any
bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or any
substantial part of the property of the Company, or shall consent to any such relief or to the appointment of or 

27

 

taking
possession by any such official in an involuntary case or other proceeding commenced against the Company, or shall make a general assignment for the benefit of creditors, or shall fail
generally to pay its debts as they become due; or 

        (g)   an
involuntary case or other proceeding shall be commenced against the Company seeking liquidation, reorganization or other relief with respect to the Company or its
debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company
or any substantial part of the property of the Company, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of sixty (60) consecutive days; or 

        (h)   default
in the payment of principal when due at stated maturity or resulting in acceleration of other Indebtedness of the Company for borrowed money where the aggregate
principal amount with respect to which the default or acceleration has occurred exceeds $20 million (or $25 million following the redemption of the Company's 5.75% Convertible
Subordinated Notes Due 2006 which are outstanding on the date hereof) and such acceleration has not been rescinded or annulled within a period of 60 days after written notice of such failure,
requiring the Company to remedy the same, shall have been given to the Company by the Trustee, or to the Company and the Trustee by the holders of at least 25% in aggregate principal amount of the
Notes at the time outstanding determined in accordance with Section 10.04; 

then,
and in each and every such case (other than an Event of Default specified in Section 8.01(f) or 8.01(g)), unless the principal of all of the Notes shall have already become due and
payable, either the Trustee or the holders of not less than twenty-five percent (25%) in aggregate principal amount of the Notes then outstanding hereunder determined in accordance with
Section 10.04, by notice in writing to the Company (and to the Trustee if given by Noteholders), may declare the principal of and premium, if any, on all the Notes and the interest and
Liquidated Damages, if any, accrued thereon to be due and payable immediately, and upon any such declaration the same shall become and shall be immediately due and payable, anything in this Indenture
or in the Notes contained to the contrary notwithstanding. If an Event of Default specified in Section 8.01(f) or 8.01(g) occurs, the principal of all the Notes and the interest and Liquidated
Damages, if any, accrued thereon shall be immediately and automatically due and payable without necessity of further action. This provision, however, is subject to the conditions that if, at any time
after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter
provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay all matured installments of interest and Liquidated Damages, if any, upon all Notes and the principal of and
premium, if any, on any and all
Notes which shall have become due otherwise than by acceleration (with interest on overdue installments of interest and Liquidated Damages, if any (to the extent that payment of such interest is
enforceable under applicable law) and on such principal and premium, if any, at the rate borne by the Notes, to the date of such payment or deposit) and amounts due to the Trustee pursuant to
Section 9.06, and if any and all defaults under this Indenture, other than the nonpayment of principal of and premium, if any, and accrued interest and Liquidated Damages, if any, on Notes
which shall have become due by acceleration, shall have been cured or waived pursuant to Section 8.07, then and in every such case the holders of a majority in aggregate principal amount of the
Notes then outstanding, by written notice to the Company and to the Trustee, may waive all defaults or Events of Default and rescind and annul such declaration and its consequences; but no such waiver
or rescission and annulment shall extend to or shall affect any subsequent default or Event of Default, or shall impair any right consequent thereon. The Company shall notify in writing a Responsible
Officer of the Trustee, promptly upon becoming aware thereof, of any Event of Default. 

        In
case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because of such waiver or rescission and 

28

 

annulment
or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the holders of Notes, and the Trustee shall be restored respectively
to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the holders of Notes, and the Trustee shall continue as though no such proceeding had been taken. 

        Section 8.02.    Payments of Notes on Default; Suit
Therefor.    The Company covenants that (a) in case default shall be made in the payment of any installment of interest or Liquidated Damages, if any, upon any
of the Notes as and when the same shall become due and payable, and such default shall have continued for a period of thirty (30) days, or (b) in case default shall be made in the
payment of the principal of or premium, if any, on any of the Notes as and when the same shall have become due and payable, whether at maturity of the Notes or in connection with any redemption, by or
under this Indenture, declaration or otherwise, then, upon demand of the Trustee, the Company will pay to the Trustee, for the benefit of the holders of the Notes, the whole amount that then shall
have become due and payable on all such Notes for principal and premium, if any, or interest and Liquidated Damages, if any, as the case may be, with interest upon the overdue principal and premium,
if any, and (to the extent that payment of such interest is enforceable under applicable law) upon the overdue installments of interest and Liquidated Damages, if any, at the rate borne by the Notes,
plus 1% and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including reasonable compensation to the Trustee, its agents, attorneys and
counsel, and all other amounts due the Trustee under Section 9.06. Until such demand by the Trustee, the Company may pay the principal of and premium, if any, and interest and Liquidated
Damages, if any, on the Notes to the registered holders, whether or not the Notes are overdue. 

        In
case the Company shall fail forthwith to pay such amounts upon such demand, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to
institute any actions or proceedings at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceeding to judgment or final decree, and may enforce
any such judgment or final
decree against the Company or any other obligor on the Notes and collect in the manner provided by law out of the property of the Company or any other obligor on the Notes wherever situated the monies
adjudged or decreed to be payable. 

        In
case there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the Notes under Title 11 of the United States Code, or any
other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the
Company or such other obligor, the property of the Company or such other obligor, or in the case of any other judicial proceedings relative to the Company or such other obligor upon the Notes, or to
the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 8.02, shall be entitled and empowered, by intervention in such
proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal, premium, if any, and interest and Liquidated Damages, if any, owing and unpaid in respect of the Notes,
and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and of the Noteholders
allowed in such judicial proceedings relative to the Company or any other obligor on the Notes, its or their creditors, or its or their property, and to collect and receive any monies or other
property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due the Trustee under Section 9.06, and to take any other action with respect
to such claims, including participating as a member of any official committee of creditors, as it reasonably deems necessary or advisable, and, unless prohibited by law or applicable regulations, and
any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the 

29

 

Noteholders
to make such payments to the Trustee, and, in the event that the Trustee shall consent to the making of such payments directly to the Noteholders, to pay to the Trustee any amount due it
for reasonable compensation, expenses, advances and disbursements, including counsel fees and expenses incurred by it up to the date of such distribution. To the extent that such payment of reasonable
compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out
of, any and all distributions, dividends, monies, securities and other property which the holders of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan
of reorganization or arrangement or otherwise. 

        All
rights of action and of asserting claims under this Indenture, or under any of the Notes, may be enforced by the Trustee without the possession of any of the Notes, or the production
thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery
of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the
holders of the Notes. 

        In
any proceedings brought by the Trustee (and in any proceedings involving the interpretation of any provision of this Indenture to which the Trustee shall be a party) the Trustee shall
be held to represent all the holders of the Notes, and it shall not be necessary to make any holders of the Notes parties to any such proceedings. 

        Section 8.03.    Application of Monies Collected By Trustee.    Any monies collected by the Trustee pursuant to
this Article 8 shall be applied in the order following, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several Notes, and stamping
thereon the payment, if only partially paid, and upon surrender thereof, if fully paid: 

        FIRST:
To the payment of all amounts due the Trustee under Section 9.06; 

        SECOND:
In case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of interest and Liquidated Damages on the Notes in default in the order of
the maturity of the installments of such interest and Liquidated Damages, with interest and Liquidated Damages (to the extent that such interest and Liquidated Damages have been collected by the
Trustee) upon the overdue installments of interest at the rate borne by the Notes, such payments to be made ratably to the Persons entitled thereto; 

        THIRD:
In case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment of the whole amount then owing and unpaid upon the
Notes for principal and premium, if any, and interest and Liquidated Damages, with interest on the overdue principal and premium, if any, and (to the extent that such interest has been collected by
the Trustee) upon overdue installments of interest at the rate borne by the Notes, and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then
to the payment of such principal and premium, if any, and interest and Liquidated Damages without preference or priority of principal and premium, if any, over interest, or of interest and Liquidated
Damages over principal and premium, if any, or of any installment of interest and Liquidated Damages over any other installment of interest and Liquidated Damages, or of any Note over any other Note,
ratably to the aggregate of such principal and premium, if any, and accrued and unpaid interest and Liquidated Damages; and 

        FOURTH:
To the payment of the remainder, if any, to the Company or any other Person lawfully entitled thereto. 

        Section 8.04.    Proceedings by Noteholder.    No Noteholder shall have any right by virtue of or by reference
to any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver, trustee, 

30

 

liquidator,
custodian or other similar official, or for any other remedy hereunder, unless such holder previously shall have given to the Trustee written notice of an Event of Default and of the
continuance thereof, as hereinbefore provided, and unless also the holders of not less than twenty-five percent (25%) in aggregate principal amount of the Notes then outstanding shall have
made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee such reasonable security or indemnity as
it may require against the costs, expenses and liabilities to be incurred therein or thereby, and the Trustee for sixty (60) days after its receipt of such notice, request and offer of
indemnity, shall have neglected or refused to institute any such action, suit or proceeding and no direction inconsistent with such written request shall have been given to the Trustee pursuant to
Section 8.07; it being understood and intended, and being expressly covenanted by the taker and holder of every Note with every other taker and holder and the Trustee, that no one or more
Noteholders shall have any right in any manner whatever by virtue of or by reference to any provision of this Indenture to affect, disturb or prejudice the rights of any other holder of Notes, or to
obtain or seek to obtain priority over or preference to any other such holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common
benefit of all Noteholders (except as otherwise provided herein). For the protection and enforcement of this Section 8.04, each and every Noteholder and the Trustee shall be entitled to such
relief as can be given either at law or in equity. 

        Notwithstanding
any other provision of this Indenture and any provision of any Note, the right of any Noteholder to receive payment of the principal of and premium, if any (including the
redemption price upon redemption pursuant to Article 8), and accrued interest on such Note, on or after the respective due dates expressed in such Note or in the event of redemption, or to
institute suit for the enforcement of any such payment on or after such respective dates against the Company shall not be impaired or affected without the consent of such Noteholder. 

        Anything
in this Indenture or the Notes to the contrary notwithstanding, any Noteholder, without the consent of either the Trustee or any other Noteholder, in its own behalf and for its
own benefit, may enforce, and may institute and maintain any proceeding suitable to enforce, its rights of conversion as provided herein. 

        Section 8.05.    Proceedings By Trustee.    In case of an Event of Default, the Trustee may, in its discretion,
proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in equity
or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power
granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law. 

        Section 8.06.    Remedies Cumulative And Continuing.    Except as provided in Section 2.06, all powers
and remedies given by this Article 8 to the Trustee or to the Noteholders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and
remedies available to the Trustee or the Noteholders, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no
delay or omission of the Trustee or of any Noteholder to exercise any right or power accruing upon any default or Event of Default occurring and continuing as aforesaid shall impair any such right or
power, or shall be construed to be a waiver of any such default or any acquiescence therein, and, subject to the provisions of Section 8.04, every power and remedy given by this
Article 8 or by law to the Trustee or to the Noteholders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Noteholders. 

        Section 8.07.    Direction of Proceedings and Waiver of Defaults By Majority of Noteholders.    The holders of
a majority in aggregate principal amount of the Notes at the time outstanding determined in 

31

 

accordance
with Section 10.04 shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power
conferred on the Trustee; provided that (a) such direction shall not be in conflict with any rule of law or with this Indenture, (b) the
Trustee may take any other action which is not inconsistent with such direction, (c) the Trustee may decline to take any action that would benefit some Noteholder to the detriment of other
Noteholders and (d) the Trustee may decline to take any action that would involve the Trustee in personal liability. The holders of a majority in aggregate principal amount of the Notes at the
time outstanding determined in accordance with Section 10.04 may, on behalf of the holders of all of the Notes, waive any past, current or future breach of any provision hereof, or default or
Event of Default hereunder and its consequences except (i) a default in the payment of Interest or premium, if any, on, or the principal of, the Notes, (ii) a failure by the Company to
convert any Notes into Common Stock, (iii) a default in the payment of the redemption price pursuant to Article 3 or (iv) a default in respect of a covenant or provisions hereof
which under Article 12 cannot be modified or amended without the consent of the holders of each or all Notes then outstanding or affected thereby. Upon any such waiver, the Company, the Trustee
and the holders of the Notes shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent other breach of any provision hereof or other default
or Event of Default or impair any right consequent thereon. Whenever any other breach of any provision hereof or default or Event of Default hereunder shall have been waived as permitted by this
Section 8.07, said other breach of any provision hereof or default or Event of Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and to be not
continuing; but no such waiver shall extend to any subsequent other breach of any provision hereof or other default or Event of Default or impair any right consequent thereon. 

        Section 8.08.    Notice of Defaults.    The Trustee shall, within ninety (90) days after a Responsible
Officer of the Trustee has knowledge of the occurrence of a default, mail to all Noteholders, as the names and addresses of such holders appear upon the Note Register, notice of all defaults known to
a Responsible Officer, unless such defaults shall have been cured or waived before the giving of such notice; provided that except in the case of
Default in the payment of the principal of, or premium, if any, or interest or Liquidated Damages on any of the Notes, the Trustee shall be protected in withholding such notice if
and so long as a trust committee of directors and/or Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interests of the Noteholders. 

        Section 8.09.    Undertaking To Pay Costs.    All parties to this Indenture agree, and each Noteholder by his
acceptance thereof shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against
the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion
assess reasonable costs, including reasonable attorneys' fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by
such party litigant; provided that the provisions of this Section 8.09 (to the extent permitted by law) shall not apply to any suit instituted by
the Trustee, to any suit instituted by any Noteholder, or group of Noteholders, holding in the aggregate more than ten percent in principal amount of the Notes at the time outstanding determined in
accordance with Section 10.04, or to any suit instituted by any Noteholder for the enforcement of the payment of the principal of or premium, if any, or interest on any Note on or after the due
date expressed in such Note or to any suit for the enforcement of the right to convert any Note in accordance with the provisions of Article 16.

ARTICLE 9

THE TRUSTEE  

        Section 9.01.    Duties and Responsibilities of Trustee.    The Trustee, prior to the occurrence of an Event of
Default and after the curing of all Events of Default which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event
of Default has occurred (which has not been cured or waived), the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in
their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his own affairs. 

        No
provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct,
except that: 

        (a)   prior
to the occurrence of an Event of Default and after the curing or waiving of all Events of Default which may have occurred: 

        (i)    the
duties and obligations of the Trustee shall be determined solely by the express provisions of this Indenture and the Trust Indenture Act, and the Trustee shall not
be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture and the
Trust Indenture Act against the Trustee; and 

        (ii)   in
the absence of bad faith and willful misconduct on the part of the Trustee, the Trustee may conclusively rely as to the truth of the statements and the correctness
of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but, in the case of any such certificates or
opinions which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the
requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein); 

        (b)   the
Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or Officers of the Trustee, unless the Trustee was negligent in
ascertaining the pertinent facts; 

        (c)   the
Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the written direction of the holders of
not less than a majority in principal amount of the Notes at the time outstanding determined as provided in Section 10.04 relating to the time, method and place of conducting any proceeding for
any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture; 

        (d)   whether
or not therein provided, every provision of this Indenture relating to the conduct or affecting the liability of, or affording protection to, the Trustee shall
be subject to the provisions of this Section; 

        (e)   the
Trustee shall not be liable in respect of any payment (as to the correctness of amount, entitlement to receive or any other matters relating to payment) or notice
effected by the Company or any paying agent or any records maintained by any co-registrar with respect to the Notes; 

        (f)    if
any party fails to deliver a notice relating to an event the fact of which, pursuant to this Indenture, requires notice to be sent to the Trustee, the Trustee may
conclusively rely on its failure to receive such notice as reason to act as if no such event occurred; and 

33

 

        (g)   the
Trustee shall not be deemed to have knowledge of any Default or Event of Default hereunder unless it shall have been notified in writing of such Default or Event of
Default by the Company or the holders of at least 10% in aggregate principal amount of the Notes. 

        None
of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of
its duties or in the exercise of any of its rights or powers, if there is reasonable ground for believing that the repayment of such funds or adequate indemnity against such risk or liability is not
reasonably assured to it. 

        Section 9.02.    Reliance on Documents, Opinions, Etc.    Except as otherwise provided in Section 9.01: 

        (a)   the
Trustee may conclusively rely and shall be protected in acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent,
order, bond, Note, note, coupon or other paper or document (whether in its original or facsimile form) believed by it in good faith to be genuine and to have been signed or presented by the proper
party or parties; 

        (b)   any
request, direction, order or demand of the Company mentioned herein shall be sufficiently evidenced by an Officers' Certificate (unless other evidence in respect
thereof be herein specifically prescribed); and any resolution of the Board of Directors may be evidenced to the Trustee by a copy thereof certified by the Secretary or an Assistant Secretary of the
Company; 

        (c)   the
Trustee may consult with counsel of its own selection and any advice or Opinion of Counsel shall be full and complete authorization and protection in respect of any
action taken or omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel; 

        (d)   the
Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the
Noteholders pursuant to the provisions of this Indenture, unless such Noteholders shall have offered to the Trustee reasonable security or indemnity satisfactory to it against the costs, expenses and
liabilities which may be incurred therein or thereby; 

        (e)   the
Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice,
request, direction, consent, order, bond, Note or other paper or document, but the Trustee may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the
Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the sole
cost of the Company and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation; 

        (f)    the
Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall
not be responsible for any misconduct or negligence on the part of any agent or attorney appointed by it with due care hereunder; 

        (g)   the
Trustee shall not be liable for any action taken, suffered or omitted to be taken by it in good faith and reasonably believed by it to be authorized or within the
discretion or rights or powers conferred upon it by this Indenture; 

        (h)   the
rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall
be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder; 

34

  

        (i)    the
Trustee may request that the Company deliver an Officers' Certificate setting forth the names of individuals and/or titles of officers authorized at such time to
take specified actions pursuant to this Indenture, which Officers' Certificate may be signed by any person authorized to sign an Officers' Certificate, including any person specified as so authorized
in any such certificate previously delivered and not superseded; 

        (j)    any
permissive right or authority granted to the Trustee shall not be construed as a mandatory duty; and 

        (k)   in
no event shall the Trustee be responsible or liable for special, indirect or consequential loss or damage of any kind whatsoever (including, but not limited to, loss
of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. 

        Section 9.03.    No Responsibility For Recitals, Etc.    The recitals contained herein and in the Notes (except
in the Trustee's certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the Notes. The Trustee shall not be accountable for the use or application by the Company of any Notes or the proceeds of any
Notes authenticated and delivered by the Trustee in conformity with the provisions of this Indenture. 

        Section 9.04.    Trustee, Paying Agents, Conversion Agents or Registrar May Own Notes.    The Trustee, any
paying agent, any conversion agent or Note Registrar, in its individual or any other capacity, may become the owner or pledgee of Notes with the same rights it would have if it were not Trustee,
paying agent, conversion agent or Note Registrar. 

        Section 9.05.    Monies to Be Held in Trust.    Subject to the provisions of Section 14.04, all monies
received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received. Money held by the Trustee in trust hereunder need not be
segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as may be agreed in writing from
time to time by the Company and the Trustee. 

        Section 9.06.    Compensation and Expenses of Trustee.    The Company covenants and agrees to pay to the
Trustee from time to time, and the Trustee shall be entitled to, such compensation for all services rendered by it hereunder in any capacity (which shall not be limited by any provision of law in
regard to the compensation of a trustee of an express trust) as mutually agreed to from time to time in writing between the Company and the Trustee, and the Company will pay or reimburse the Trustee
upon its request for all reasonable expenses, disbursements and advances reasonably incurred or made by the Trustee in accordance with any of the provisions of this Indenture (including the reasonable
compensation and the expenses and disbursements of its counsel and of all Persons not regularly in its employ) except any such expense, disbursement or advance as may arise from its negligence or bad
faith. The Company also covenants to indemnify the Trustee and any predecessor Trustee (and any officer, director or employee of the Trustee), in any capacity under this Indenture and its agents and
any authenticating agent for, and to hold them harmless against, any and all loss, liability, damage, claim or expense including taxes (other than taxes based on the income of the Trustee) incurred
without negligence or bad faith on the part of the Trustee or such officers, directors, employees and agent or authenticating agent, as the case may be, and arising out of or in connection with the
acceptance or administration of this trust or in any other capacity hereunder, including the costs and expenses of defending themselves against any claim (whether asserted by the Company, any holder
or any other Person) or liability in connection with enforcing the provisions of the Section 9.06, except to the extent that such loss, damage, claim, liability or expense is due to its own
negligence or bad faith. The obligations of the Company under this Section 9.06 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and
advances shall be secured by a lien prior 

35

 

to
that of the Notes upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the holders of particular Notes. The obligation of the Company
under this Section shall survive the satisfaction and discharge of this Indenture and the resignation or removal of the Trustee. 

        When
the Trustee and its agents and any authenticating agent incur expenses or render services after an Event of Default specified in Section 8.01(f) or (g) with respect to
the Company occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any bankruptcy, insolvency or similar laws. 

        Section 9.07.    Officers' Certificate As Evidence.    Except as otherwise provided in Section 9.01,
whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or omitting any action
hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of bad faith or willful misconduct on the part of the Trustee, be deemed to be
conclusively proved and established by an Officers' Certificate delivered to the Trustee. 

        Section 9.08.    Conflicting Interests of Trustee.    If the Trustee has or shall acquire a conflicting
interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the
Trust Indenture Act and this Indenture. 

        Section 9.09.    Eligibility of Trustee.    There shall at all times be a Trustee hereunder which shall be a
Person that is eligible pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus of at least $50,000,000 (or if such Person is a member of a bank holding company
system, its bank holding company shall have a combined capital and surplus of at least $50,000,000). If such Person publishes reports of condition at least annually, pursuant to law or to the
requirements of any supervising or examining authority, then for the purposes of this Section the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 9.09, it shall resign
immediately in the manner and with the effect hereinafter specified in this Article. 

        Section 9.10.    Resignation or Removal of Trustee.    

        (a)   The
Trustee may at any time resign by giving written notice of such resignation to the Company and to the holders of Notes. Upon receiving such notice of resignation,
the Company shall promptly appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the
resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment sixty (60) days after the mailing of such notice of
resignation to the Noteholders, the resigning Trustee may, upon ten (10) Business Days' notice to the Company and the Noteholders, appoint a successor identified in such notice or may petition,
at the expense of the Company, any court of competent jurisdiction for the appointment of a successor trustee, or, if any Noteholder who has been a bona fide holder of a Note or Notes for at least six
(6) months may, subject to the provisions of Section 8.09, on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee.
Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee. 

        (b)   In
case at any time any of the following shall occur: 

        (i)    the
Trustee shall fail to comply with Section 9.08 after written request therefor by the Company or by any Noteholder who has been a bona fide holder of a Note or
Notes for at least six (6) months; or 

36

 

        (ii)   the
Trustee shall cease to be eligible in accordance with the provisions of Section 9.09 and shall fail to resign after written request therefor by the Company
or by any such Noteholder; or 

        (iii)  the
Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any
public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation; 

then,
in any such case, the Company may remove the Trustee and appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which
instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of Section 8.09, any Noteholder who has been a bona fide holder of a
Note or Notes for at least six (6) months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor trustee; provided that if no successor Trustee shall have been appointed and have accepted appointment sixty (60) days
after either the Company or the Noteholders has removed the Trustee, or the Trustee resigns, the Trustee so removed may petition, at the expense of the Company, any court of competent jurisdiction for
an appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. 

        (c)   The
holders of a majority in aggregate principal amount of the Notes at the time outstanding may at any time remove the Trustee and nominate a successor trustee which
shall be deemed appointed as successor trustee unless, within ten (10) days after notice to the Company of such nomination, the Company objects thereto, in which case the Trustee so removed or
any Noteholder, or if such Trustee so removed or any Noteholder fails to act, the Company, upon the terms and conditions and otherwise as in Section 9.10(a) provided, may petition any court of
competent jurisdiction for an appointment of a successor trustee. 

        (d)   Any
resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 9.10 shall become effective
upon acceptance of appointment by the successor trustee as provided in Section 9.11. 

        (e)   Notwithstanding
the replacement of the Trustee pursuant to this Section, the Company's obligations under Section 9.06 shall continue for the benefit of the
retiring Trustee. 

        Section 9.11.    Acceptance by Successor Trustee.    Any successor trustee appointed as provided in
Section 9.10 shall execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of
the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its
predecessor hereunder, with like effect as if originally named as trustee herein; but, nevertheless, on the written request of the Company or of the successor trustee, the trustee ceasing to act
shall, upon payment of any amount then due it pursuant to the provisions of Section 9.06, execute and deliver an instrument transferring to such successor trustee all the rights and powers of
the trustee so ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such
successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a lien upon all property and funds held or collected by such
trustee as such, except for funds held in trust for the benefit of holders of particular Notes, to secure any amounts then due it pursuant to the provisions of Section 9.06. 

        No
successor trustee shall accept appointment as provided in this Section 9.11 unless, at the time of such acceptance, such successor trustee shall be qualified under the
provisions of Section 9.08 and be eligible under the provisions of Section 9.09. 

37

 

        Upon
acceptance of appointment by a successor trustee as provided in this Section 9.11, the Company (or the former trustee, at the written direction of the Company) shall mail or
cause to be mailed notice of the succession of such trustee hereunder to the holders of Notes at their addresses as they shall appear on the Note Register. If the Company fails to mail such notice
within ten (10) days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Company. 

        Section 9.12.    Succession By Merger.    Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or
substantially all of the corporate trust business of the Trustee (including any trust created by this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any
paper or any further act on the part of any of the parties hereto, provided that in the case of any corporation succeeding to all or substantially all
of the corporate trust business of the Trustee, such corporation shall be qualified under the provisions of Section 9.08 and eligible under the provisions of Section 9.09. 

        In
case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture, any of the Notes shall have been authenticated but not delivered, any such
successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by such predecessor trustee, and deliver such Notes so authenticated;
and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or any authenticating agent appointed by such successor trustee may authenticate such Notes in
the name of the successor trustee; and in all such cases such certificates shall have the full force that is provided in the Notes or in this Indenture;  provided that the right to adopt the certificate
of authentication of any predecessor Trustee or authenticate Notes in the name of any predecessor
Trustee shall apply only to its successor or successors by merger, conversion or consolidation. 

        Section 9.13.    Preferential Collection of Claims.    If and when the Trustee shall be or become a creditor of
the Company (or any other obligor upon the Notes), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of the claims against the Company (or any such
other obligor). 

ARTICLE 10

THE NOTEHOLDERS  

        Section 10.01.    Action By Noteholders.    Whenever in this Indenture it is provided that the holders of a
specified percentage in aggregate principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any
other action), the fact that at the time of taking any such action, the holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of
instruments of similar tenor executed by Noteholders in person or by agent or proxy appointed in writing, or (b) by the record of the holders of Notes voting in favor thereof at any meeting of
Noteholders duly called and held in accordance with the provisions of Article 11, or (c) by a combination of such instrument or instruments and any such record of such a meeting of
Noteholders. Whenever the Company or the Trustee solicits the taking of any action by the holders of the Notes, the Company or the Trustee may fix in advance of such solicitation, a date as the record
date for determining holders entitled to take such action. The record date shall be not more than fifteen (15) days prior to the date of commencement of solicitation of such action. 

        Section 10.02.    Proof of Execution by Noteholders.    Subject to the provisions of Sections 9.01, 9.02 and
11.05, proof of the execution of any instrument by a Noteholder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the 

38

 

Trustee
or in such manner as shall be satisfactory to the Trustee. The holding of Notes shall be proved by the registry of such Notes or by a certificate of the Note Registrar. 

        The
record of any Noteholders' meeting shall be proved in the manner provided in Section 11.06. 

        Section 10.03.    Who Are Deemed Absolute Owners.    The Company, the Trustee, any paying agent, any conversion
agent and any Note Registrar may deem the Person in whose name such Note shall be registered upon the Note Register to be, and may treat it as, the absolute owner of such Note (whether or not such
Note shall be overdue and notwithstanding any notation of ownership or other writing thereon made by any Person other than the Company or any Note Registrar) for the purpose of receiving payment of or
on account of the principal of, premium, if any, and interest on such Note, for conversion of such Note and for all other purposes; and neither the Company nor the Trustee nor any paying agent nor any
conversion agent nor any Note Registrar shall be affected by any notice to the contrary. All such payments so made to any holder for the time being, or upon his order, shall be valid, and, to the
extent of the sum or sums so paid, effectual to satisfy and discharge the liability for monies payable upon any such Note. 

        Section 10.04.    Company-owned Notes Disregarded.    In determining whether the holders of the requisite
aggregate principal amount of Notes have concurred in any direction, consent, waiver or other action under this Indenture, Notes which are owned by the Company or any other obligor on the Notes or any
Affiliate of the Company or any other obligor on the Notes shall be disregarded and deemed not to be outstanding for the purpose of any such determination;  provided that for the purposes of determining
whether the Trustee shall be protected in relying on any such direction, consent, waiver or other action,
only Notes which a Responsible Officer actually knows are so owned shall be so disregarded. Notes so owned which have been pledged in good faith may be regarded as outstanding for the purposes of this
Section 10.04 if the pledgee shall establish to the satisfaction of the Trustee the pledgee's right to vote such Notes and that the pledgee is not the Company, any other obligor on the Notes or
any Affiliate of the Company or any such other obligor. In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee.
Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officers' Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for
the account of any of the above described Persons, and, subject to Section 9.01, the Trustee shall be entitled to accept such Officers' Certificate as conclusive evidence of the facts therein
set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination. 

        Section 10.05.    Revocation Of Consents, Future Holders Bound.    At any time prior to (but not after) the
evidencing to the Trustee, as provided in Section 10.01, of the taking of any action by the holders of the percentage in aggregate principal amount of the Notes specified in this Indenture in
connection with such action, any holder of a Note which is shown by the evidence to be included in the Notes the holders of which have consented to such action may, by filing written notice with the
Trustee at its Corporate Trust Office and upon proof of holding as provided in Section 10.02, revoke such action so far as concerns such Note. Except as aforesaid, any such action taken by the
holder of any Note shall be conclusive and binding upon such holder and upon all future holders and owners of such Note and of any Notes issued in exchange or substitution therefor, irrespective of
whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor. 

ARTICLE 11

place of such meeting and in general terms the action proposed to be taken at such meeting and the establishment of any record date pursuant to Section 10.01, shall be mailed to holders of
Notes at their addresses as they shall appear on the Note Register. Such notice shall also be mailed to the Company. Such notices shall be mailed not less than twenty (20) nor more than ninety
(90) days prior to the date fixed for the meeting. 

        Any

Noteholders, by written request setting forth in reasonable detail the action proposed to be taken at the meeting, and the Trustee shall not have mailed the notice of such meeting within twenty
(20) days after receipt of such request, then the Company or such Noteholders may determine the time and the place for such meeting and may call such meeting to take any action authorized in
Section 11.01, by mailing notice thereof as provided in Section 11.02. 

        Section 11.04.    Qualifications For Voting.    To be entitled to vote at any meeting of Noteholders a person

duties of inspectors of votes, the submission and examination of proxies, certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall
think fit. 

        The
Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the Company or by Noteholders as provided in
Section 11.03, in which case the Company or the Noteholders calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent
secretary

of
the meeting shall be elected by vote of the holders of a majority in principal amount of the Notes represented at the meeting and entitled to vote at the meeting. 

        Subject
to the provisions of Section 10.04, at any meeting each Noteholder or proxyholder shall be entitled to one vote for each $1,000 principal amount of Notes held or
represented by him; provided that no vote shall be cast or counted at any meeting in respect of any Note challenged as not outstanding and ruled by the
chairman of the meeting to be not outstanding. The chairman of the meeting shall have no right to vote other than by virtue of Notes held by him or instruments in writing as aforesaid duly designating
him as the proxy to vote on behalf of other Noteholders. Any meeting of Noteholders duly called pursuant to the provisions of Section 11.02 or 11.03 may be adjourned from time to time by the

The permanent chairman of the meeting shall appoint two inspectors of votes who shall count all votes cast at the meeting for or against any resolution and who shall make and file with the secretary
of the meeting their verified written reports in duplicate of all votes cast at the meeting. A record in duplicate of the proceedings of each meeting of Noteholders shall be prepared by the secretary
of the meeting and there shall be attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that said notice was mailed as provided
in Section 11.02. The record shall show the principal amount of the Notes voting in favor of or against any resolution. The record shall be signed and verified by the affidavits of the
permanent chairman and secretary of the meeting and one of the duplicates shall be delivered to the Company and the other to the Trustee to be preserved by the Trustee, the latter to have attached
thereto the ballots voted at the meeting. 

        Any
record so signed and verified shall be conclusive evidence of the matters therein stated. 

        Section 11.07.    No Delay Of Rights By Meeting.    Nothing contained in this Article 11 shall be deemed
or construed to authorize or permit, by reason of any call of a meeting of Noteholders or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay in the
exercise of any right or rights conferred upon or reserved to the Trustee or to the Noteholders under any of the provisions of this Indenture or of the Notes. 

ARTICLE 12

permitting the enforcement of all or any of the several remedies provided in this Indenture as herein set forth; provided that in respect of any such
additional covenant, restriction or condition, such supplemental indenture may provide for a particular period of grace after default (which period may be shorter or longer than that allowed in the

        Upon
the written request of the Company, accompanied by a copy of the resolutions of the Board of Directors certified by its Secretary or Assistant Secretary authorizing the execution of
any supplemental indenture, the Trustee is hereby authorized to join with the Company in the execution of any such supplemental indenture, to make any further appropriate agreements and stipulations

supplemental indenture authorized by the provisions of this Section 12.01 may be executed by the Company and the Trustee without the consent of the holders of any of the Notes
at the time outstanding, notwithstanding any of the provisions of Section 12.02. 

        Section 12.02.    Supplemental Indenture With Consent Of Noteholders.    With the consent (evidenced as

shall not be obligated to, enter into such supplemental indenture. 

        It
shall not be necessary for the consent of the Noteholders under this Section 12.02 to approve the particular form of any proposed supplemental indenture, but it shall be
sufficient if such consent shall approve the substance thereof. 

        Section 12.03.    Effect Of Supplemental Indenture.    Any supplemental indenture executed pursuant to the
provisions of this Article 12 shall comply with the Trust Indenture Act, as then in effect, provided that this Section 12.03 shall not
require such supplemental indenture or the Trustee to be qualified under the Trust Indenture Act prior to the time such qualification is in fact required under the terms of the Trust Indenture Act or
the Indenture has been qualified under the Trust Indenture Act, nor shall it constitute any admission or acknowledgment by any party to such supplemental indenture that any such qualification is
required prior to the time such qualification is in fact required under the terms of the Trust Indenture Act or the Indenture has been qualified under the Trust Indenture Act. Upon the execution of
any supplemental indenture pursuant to the provisions of this Article 12, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights,
limitation of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company and the holders of Notes shall thereafter be determined, exercised and enforced hereunder,
subject in all respects to such modifications and amendments and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of this
Indenture for any and all purposes. 

        Section 12.04.    Notation On Notes.    Notes authenticated and delivered after the execution of any
supplemental indenture pursuant to the provisions of this Article 12 may bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the
Company or the Trustee shall so determine, new Notes so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any modification of this Indenture contained in any such
supplemental indenture may, at the Company's expense, be prepared and executed by the Company, authenticated by the Trustee (or an authenticating agent duly appointed by the Trustee pursuant to
Section 17.10) and delivered in exchange for the Notes then outstanding, upon surrender of such Notes then outstanding. 

43

   
        Section 12.05.    Evidence Of Compliance Of Supplemental Indenture To Be Furnished To Trustee.    Prior to
entering into any supplemental indenture, the Trustee shall be provided with an Officers' Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture executed pursuant
hereto complies with the requirements of this Article 12 and is otherwise authorized or permitted by this Indenture. 

ARTICLE 13

CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE  

        Section 13.01.    Company May Consolidate On Certain Terms.    Subject to the provisions of
Section 13.02, the Company shall not consolidate or merge with or into any other Person or Persons (whether or not affiliated with the Company), nor shall the Company or its successor or
successors be a party or parties to successive consolidations or mergers, nor shall the Company sell, convey, transfer or lease the property and assets of the Company substantially as an entirety, to
any other Person (whether or not affiliated with the Company), unless: (i) the Company is the surviving Person, or the resulting, surviving or transferee Person is organized and existing under
the laws of the United States of America, any state thereof, the District of Columbia or any other country; (ii) upon any such consolidation, merger, sale, conveyance, transfer or lease, the
due and punctual payment of the principal of and premium, if any, and interest on all of the Notes, according to their tenor and the due and punctual performance and observance of all of the covenants
and conditions of this Indenture to be performed by the Company, shall be expressly assumed, by supplemental indenture satisfactory in form to the Trustee, executed and delivered to the Trustee, by
the Person (if other than the Company) formed by such consolidation, or into which the Company shall have been merged, or by the Person that shall have acquired or leased such property, and such
supplemental indenture shall provide for the applicable conversion rights set forth in Section 16.06; and (iii) immediately after giving effect to the transaction described above, no
Event of Default, and no event which, after notice or lapse of time or both, would become an Event of Default, shall have happened and be continuing. 

        Section 13.02.    Successor To Be Substituted.    In case of any such consolidation, merger, sale, conveyance,
transfer or lease and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual
payment of the principal of and premium, if any, and interest on all of the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the
Company, such successor Person shall succeed to and be substituted for the Company, with the same effect as if it had been named herein as the party of this first part. Such successor Person thereupon
may cause to be signed, and may issue either in its own name or in the name of InterMune, Inc. any or all of the Notes, issuable hereunder that theretofore shall not have been signed by the
Company and delivered to the Trustee; and, upon the order of such successor Person instead of the Company and subject to all the terms, conditions and limitations in this Indenture prescribed, the
Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that previously shall have been signed and delivered by the officers of the Company to the Trustee
for authentication, and any Notes that such successor Person thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the
same legal rank and benefit under this Indenture as the Notes theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Notes had been issued at the date of
the execution hereof. In the event of any such consolidation, merger, sale, conveyance, transfer or lease, upon compliance with the provisions of this Article 13, the Person named as the
"Company" in the first paragraph of this Indenture or any successor that shall thereafter have become such in the manner prescribed in this
Article 13 may be dissolved, wound up and liquidated at any time thereafter and such Person shall be released from its liabilities as obligor and maker of the Notes and from its obligations
under this Indenture. 

44

 

        In
case of any such consolidation, merger, sale, conveyance, transfer or lease, such changes in phraseology and form (but not in substance) may be made in the Notes thereafter to be
issued as may be appropriate. 

        Section 13.03.    Opinion Of Counsel To Be Given To Trustee.    The Trustee shall receive an Officers'
Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale, conveyance, transfer or lease and any such assumption complies with the provisions of this
Article 13. 

ARTICLE 14

SATISFACTION AND DISCHARGE OF INDENTURE  

        Section 14.01.    Discharge Of Indenture.    When the Company shall deliver to the Trustee for cancellation all
Notes theretofore authenticated (other than any Notes that have been destroyed, lost or stolen and in lieu of or in substitution for which other Notes shall have been authenticated and delivered) and
not
theretofore canceled, or all the Notes not theretofore canceled or delivered to the Trustee for cancellation shall have become due and payable, and the Company shall deposit with the Trustee, in
trust, funds sufficient to pay all of the Notes (other than any Notes that shall have been mutilated, destroyed, lost or stolen and in lieu of or in substitution for which other Notes shall have been
authenticated and delivered) not theretofore canceled or delivered to the Trustee for cancellation, including principal and premium, if any, and interest and Liquidated Damages, if any, due, and if
the Company shall also pay or cause to be paid all other sums payable hereunder by the Company, then this Indenture shall cease to be of further effect (except as to (i) rights hereunder of
Noteholders to receive payments of principal of and premium, if any, and interest and Liquidated Damages, if any, on, the Notes and the other rights, duties and obligations of Noteholders, as
beneficiaries hereof with respect to the amounts, if any, so deposited with the Trustee and (ii) the rights, obligations and immunities of the Trustee hereunder), and the Trustee, on written
demand of the Company accompanied by an Officers' Certificate and an Opinion of Counsel as required by Section 17.05 and at the cost and expense of the Company, shall execute proper instruments
acknowledging satisfaction of and discharging this Indenture; the Company, however, hereby agrees to reimburse the Trustee for any costs or expenses thereafter reasonably and properly incurred by the
Trustee and to compensate the Trustee for any services thereafter reasonably and properly rendered by the Trustee in connection with this Indenture or the Notes. 

        Section 14.02.    Deposited Monies To Be Held In Trust By Trustee.    Subject to Section 14.04, all
monies deposited with the Trustee pursuant to Section 14.01, shall be held in trust for the sole benefit of the Noteholders, and such monies shall be applied by the Trustee to the payment,
either directly or through any paying agent (including the Company if acting as its own paying agent), to the holders of the particular Notes for the payment or redemption of which such monies have
been deposited with the Trustee, of all sums due and to become due thereon for principal and interest and premium, if any. 

        Section 14.03.    Paying Agent To Repay Monies Held.    Upon the satisfaction and discharge of this Indenture,
all monies then held by any paying agent of the Notes (other than the Trustee) shall, upon written request of the Company, be repaid to it or paid to the Trustee, and thereupon such paying agent shall
be released from all further liability with respect to such monies. 

        Section 14.04.    Return Of Unclaimed Monies.    Subject to the requirements of applicable law, any monies
deposited with or paid to the Trustee for payment of the principal of, premium, if any, or interest on Notes and not applied but remaining unclaimed by the holders of Notes for two years after the
date upon which the principal of, premium, if any, or interest on such Notes, as the case may be, shall have become due and payable, shall be repaid to the Company by the Trustee on demand and all
liability of the Trustee shall thereupon cease with respect to such monies; and the holder of any of the Notes shall thereafter look only to the Company for any payment that such holder may be
entitled to collect unless an applicable abandoned property law designates another Person. 

45

 

        Section 14.05.    Reinstatement.    If the Trustee or the paying agent is unable to apply any money in
accordance with Section 14.02 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company's
obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 14.01 until such time as the Trustee or the paying agent is
permitted to apply all such money in accordance with Section 14.02; provided that if the Company makes any payment of interest on or principal of
any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the holders of such Notes to receive such payment from the money held by the Trustee or paying
agent. 

ARTICLE 15

IMMUNITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS AND DIRECTORS  

        Section 15.01.    Indenture And Notes Solely Corporate Obligations.    No recourse for the payment of the
principal of or premium, if any, or Interest on any Note, or for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement of the
Company in this Indenture or in any supplemental indenture or in any Note, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder,
employee, agent, officer, 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; it being expressly understood that all such liability is hereby
expressly waived and released as a condition of, and as a consideration for, the execution of this Indenture and the issue of the Notes. 

ARTICLE 16

CONVERSION OF NOTES  

        Section 16.01.    Right To Convert.    

        (a)   Subject
to and upon compliance with the provisions of this Indenture, at any time prior to the close of business on March 1, 2011, the holder of any Note shall
have the right, at such holder's option, to convert the principal amount of the Note, or any portion of such principal amount which is a multiple of $1,000, into fully paid and
non-assessable shares of Common Stock (as such shares shall then be constituted) at the Conversion Rate in effect at such time, by surrender of the Note so to be converted in whole or in
part, together with any required funds, in the manner provided in Section 16.02. 

        (b)   A
Note in respect of which a holder is electing to exercise its option to require redemption upon a Designated Event pursuant to Section 3.05 may be converted
only if such holder withdraws its Redemption Notice in accordance with Section 3.07. A holder of Notes is not entitled to any rights of a holder of Common Stock until such holder has converted
his Notes to Common Stock, and only to the extent such Notes are deemed to have been converted to Common Stock under this Article 16. 

        Section 16.02.    Exercise Of Conversion Privilege; Issuance Of Common Stock On
Conversion; No Adjustment For Interest Or Dividends.    

        (a)   In
order to exercise the conversion privilege with respect to any Note in certificated form, the Company must receive at the office or agency of the Company maintained
for that purpose or, at the option of such holder, the Corporate Trust Office, such Note with the original or facsimile of the form entitled "Conversion
Notice" on the reverse thereof, duly completed and manually signed, together with such Notes duly endorsed for transfer, accompanied by the funds, if any, required by
Section 16.02(c). Such notice shall also state the name or names (with address or addresses) in which the certificate or 

46

 

certificates
for shares of Common Stock which shall be issuable on such conversion shall be issued, and shall be accompanied by transfer or similar taxes, if required pursuant to Section 16.07. 

        In
order to exercise the conversion privilege with respect to any interest in a Global Note, the beneficial holder must complete, or cause to be completed, the appropriate instruction
form for conversion pursuant to the Depositary's book-entry conversion program, deliver, or cause to be delivered, by book-entry delivery an interest in such Global Note,
furnish appropriate endorsements and transfer documents if required by the Company or the Trustee or conversion agent, and pay the funds, if any, required by Section 16.02(c) and any transfer
taxes if required pursuant to Section 16.07. 

        (b)   As
promptly as practicable after satisfaction of the requirements for conversion set forth above, subject to compliance with any restrictions on transfer if shares
issuable on conversion are to be issued in a name other than that of the Noteholder (as if such transfer were a transfer of the Note or Notes (or portion thereof) so converted), the Company shall
issue and shall deliver to such Noteholder at the office or agency maintained by the Company for such purpose pursuant to Section 6.02, a certificate or certificates for the number of full
shares of Common Stock issuable upon the conversion of such Note or portion thereof as determined by the Company in accordance with the provisions of this Article 16 and a check or cash in
respect of any fractional interest in respect of a share of Common Stock arising upon such conversion, calculated by the Company as provided in Section 16.03. In case any Note of a denomination
greater than $1,000 shall be surrendered for partial conversion, and subject to Section 2.03, the Company shall execute and the Trustee shall authenticate and deliver to the holder of the Note
so surrendered, without charge to him, a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note. 

        Each
conversion shall be deemed to have been effected as to any such Note (or portion thereof) on the date on which the requirements set forth above in this Section 16.02 have
been satisfied as to such Note (or portion thereof), and the Person in whose name any certificate or certificates for shares of Common Stock shall be issuable upon such conversion shall be deemed to
have become on said date the holder of record of the shares represented thereby; provided that any such surrender on any date when the stock transfer
books of the Company shall be closed shall constitute the Person in whose name the certificates are to be issued as the record holder thereof for all purposes on the next succeeding day on which such
stock transfer books are open, but such conversion shall be at the Conversion Rate in effect on the date upon which such Note shall be surrendered. 

        (c)   Any
Note or portion thereof surrendered for conversion during the period from the close of business on the record date for any interest payment date to the close of
business on the Business Day preceding the following interest payment date shall be accompanied by payment, in immediately available funds or other funds acceptable to the Company, of an amount equal
to the interest otherwise payable on such interest payment date on the principal amount being converted; provided that no such payment need be made
(1) if the Company has specified a redemption date following a Designated Event that is during such period, or (2) to the extent of any overdue interest at the time of conversion with
respect to such Note. Except as provided above in this Section 16.02, no payment or other adjustment shall be made for interest accrued on any Note converted or for dividends on any shares
issued upon the conversion of such Note as provided in this Article 16. 

        Upon
the conversion of a Note, that portion of the accrued but unpaid interest, with respect to the converted Note shall not be cancelled, extinguished or forfeited, but rather shall be
deemed to be paid in full to the holder thereof through delivery of the Common Stock (together with the cash payment, if any, in lieu of fractional shares) in exchange for the Note being converted
pursuant to the provisions hereof; and the fair market value of such shares of Common Stock (together with any such cash payment in lieu of fractional shares) shall be treated as issued, to the extent
thereof, first in exchange for and in satisfaction of our obligation to pay the principal amount of the converted Note, the accrued 

47

 

but
unpaid interest, and the balance, if any, of such fair market value of such Common Stock (and any such cash payment) shall be treated as issued in exchange for and in satisfaction of the right to
convert the Note being converted pursuant to the provisions hereof. 

        (d)   Upon
the conversion of an interest in a Global Note, the Trustee (or other conversion agent appointed by the Company), or the Custodian at the direction of the Trustee
(or other conversion agent appointed by the Company), shall make a notation on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in
writing of any conversions of Notes effected through any conversion agent other than the Trustee. 

        Section 16.03.    Cash Payments in Lieu of Fractional Shares.    No fractional shares of Common Stock or scrip
certificates representing fractional shares shall be issued upon conversion of Notes. If more than one Note shall be surrendered for conversion at one time by the same holder, the number of full
shares that shall be issuable upon conversion shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted hereby) so
surrendered. If any fractional share of stock would be issuable upon the conversion of any Note or Notes, the Company shall make an adjustment and payment therefor in cash at the current price thereof
to the holder of Notes. The current price of a share of Common Stock shall be the Closing Sale Price on the last Trading Day immediately preceding the day on which the Notes (or specified portions
thereof) are deemed to have been converted. 

        Section 16.04.    Conversion Rate.    Each $1,000 principal amount of the Notes shall be convertible into
46.2283 shares of Common Stock (herein called the "Conversion Rate"), subject to adjustment as provided in this Article 16. 

        Section 16.05.    Adjustment Of Conversion Rate.    The Conversion Rate shall be adjusted from time to time by
the Company as follows: 

        (a)   In
case the Company shall hereafter pay a dividend or make a distribution to all holders of the outstanding Common Stock in shares of Common Stock, the Conversion Rate
shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect at the opening of business on the date following the date fixed for the determination
of stockholders entitled to receive such dividend or other distribution by a fraction, 

        (i)    the
numerator of which shall be the sum of the number of shares of Common Stock outstanding at the close of business on the date fixed for the determination of
stockholders entitled to receive such dividend or other distribution plus the total number of shares of Common Stock constituting such dividend or other distribution; and 

        (ii)   the
denominator of which shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination, 

such
increase to become effective immediately after the opening of business on the day following the date fixed for such determination. For the purpose of this clause (a), the number of shares
of Common Stock at any time outstanding shall not include shares held in the treasury of the Company. The Company will not pay any dividend or make any distribution on shares of Common Stock held in
the treasury of the Company. If any dividend or distribution of the type described in this Section 16.05(a) is declared but not so paid or made, the Conversion Rate shall again be adjusted to
the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 

        (b)   In
case the Company shall issue rights or warrants to all holders of its outstanding shares of Common Stock entitling them (for a period expiring within
forty-five (45) days after the date fixed for determination of stockholders entitled to receive such rights or warrants) to subscribe for or purchase shares of Common Stock at a
price per share less than the Current Market Price on 

48

 

the
date fixed for determination of stockholders entitled to receive such rights or warrants, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the
Conversion Rate in effect immediately prior to the date fixed for determination of stockholders entitled to receive such rights or warrants by a fraction, 

        (i)    the
numerator of which shall be the number of shares of Common Stock outstanding on the date fixed for determination of stockholders entitled to receive such rights or
warrants plus the total number of additional shares of Common Stock offered for subscription or purchase, and 

        (ii)   the
denominator of which shall be the sum of the number of shares of Common Stock outstanding at the close of business on the date fixed for determination of
stockholders entitled to receive such rights or warrants plus the number of shares that the aggregate offering price of the total number of shares so offered would purchase at such Current Market
Price. 

        Such
adjustment shall be successively made whenever any such rights or warrants are issued, and shall become effective immediately after the opening of business on the day following the
date fixed for determination of stockholders entitled to receive such rights or warrants. To the extent that shares of Common Stock are not delivered after the expiration of such rights or warrants,
the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of delivery of
only the number of shares of Common Stock actually delivered. If such rights or warrants are not so issued, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in
effect if such date fixed for the determination of stockholders entitled to receive such rights or warrants had not been fixed. In determining whether any rights or warrants entitle the holders to
subscribe for or purchase shares of Common Stock at less than such Current Market Price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into
account any consideration received by the Company for such rights or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be
determined by the Board of Directors. 

        (c)   In
case outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the Conversion Rate in effect at the opening of business
on the day following the day upon which such subdivision becomes effective shall be proportionately increased, and conversely, in case outstanding shares of Common Stock shall be combined into a
smaller number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately
reduced, such increase or reduction, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes
effective. 

        (d)   In
case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock shares of any class of capital stock of the Company or evidences of
its indebtedness or assets (including securities, but excluding any rights or warrants referred to in Section 16.05(b), and excluding any dividend or distribution (x) paid exclusively in
cash or (y) referred to in Section 16.05(a) (any of the foregoing hereinafter in this Section 16.05(d)) called the "Securities")),
then, in each such case, the Conversion Rate shall be increased so that the same shall be equal to the rate determined by multiplying the Conversion Rate in effect on the Record Date with respect to
such distribution by a fraction, 

        (i)    the
numerator of which shall be the Current Market Price on such Record Date; and 

49

  

        (ii)   the
denominator of which shall be the Current Market Price on such Record Date less the Fair Market Value (as determined by the Board of Directors, whose determination
shall be conclusive, and described in a resolution of the Board of Directors) on the Record Date of the portion of the Securities so distributed applicable to one share of Common Stock, 

such
adjustment to become effective immediately prior to the opening of business on the day following such Record Date; provided that if the then fair
market value (as so determined) of the portion of the Securities so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price on the Record Date, in lieu
of the foregoing adjustment, adequate provision shall be made so that each Noteholder shall have the right to receive upon conversion the amount of Securities such holder would have received had such
holder converted each Note on the Record Date. If such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in
effect if such dividend or distribution had not been declared. If the Board of Directors determines the Fair Market Value of any distribution for purposes of this Section 16.05(d) by reference
to the actual or when issued trading market for any securities, it must in doing so consider the prices in such market over the same period used in computing the Current Market Price on the applicable
Record Date. 

        If
the dividend or distribution requiring an adjustment pursuant to this clause (d) consists of capital stock of any class or series, or similar equity interests, of or relating
to a Subsidiary or other business unit of the Company, for purposes of making such adjustment, (i) the Current Market Price shall be determined as of the date (the
"Ex-Dividend Date") on which "ex-dividend trading" commences for such distribution on the NASDAQ National Market or such other
national or regional exchange or market on which such securities are then listed or quoted, based on the average of the Closing Sale Prices of the Common Stock for the ten (10) Trading Days
commencing on and including the fifth Trading Day after the Ex-Dividend Date and (ii) the Fair Market Value of such dividend or distribution shall equal the number of securities
distributed in respect of each share of Common Stock multiplied by the average of the closing sale prices of those securities distributed for the ten (10) Trading Days commencing on and
including the fifth Trading Day after the Ex-Dividend Date. 

        Rights
or warrants distributed by the Company to all holders of Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company's capital stock (either
initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events ("Trigger Event"):
(i) are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of Common Stock, shall be
deemed not to have been distributed for purposes of this Section 16.05 (and no adjustment to the Conversion Rate under this Section 16.05 will be required) until the occurrence of the
earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this
Section 16.05(d). If any such right or warrant, including any such existing rights or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of
which such rights or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed
to be the date of distribution and record date with respect to new rights or warrants with such rights (and a termination or expiration of the existing rights or warrants without exercise by any of
the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding
sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 16.05 was made, (1) in
the case of any such rights or warrants that shall all have been redeemed or repurchased without exercise 

50

 

by
any holders thereof, the Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a
cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights or warrants (assuming such holder had retained such
rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants that shall have expired or been
terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights and warrants had not been issued. 

        For
purposes of this Section 16.05(d) and Section 16.05(a) and (b), any dividend or distribution to which this Section 16.05(d) is applicable that also includes
shares of Common Stock, or such rights or warrants to subscribe for or purchase shares of Common Stock of the type described in Section 16.05(b) (or both), shall be deemed instead to be
(1) a dividend or distribution of the evidences of indebtedness, assets or shares of capital stock other than such shares of Common Stock or rights or warrants (and any Conversion Rate
adjustment required by this Section 16.05(d) with respect to such dividend or distribution shall then be made) immediately followed by (2) a dividend or distribution of such shares of
Common Stock or such rights or warrants (and any further Conversion Rate adjustment required by Sections 16.05(a) and 16.05(b) with respect to such dividend or distribution shall then be made), except
(A) the Record Date of such dividend or distribution shall be substituted as "the date fixed for the determination of stockholders entitled to receive such dividend or other distribution", "the
date fixed for the determination of stockholders entitled to receive such rights or warrants" and "the date fixed for such determination" within the meaning of Section 16.05(a) and 16.05(b) and
(B) any shares of Common Stock included in such dividend or distribution shall not be deemed "outstanding at the close of business on the date fixed for such determination" within the meaning
of Section 16.05(a). 

        (e)   In
case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock cash, then, in such case, the Conversion Rate shall be increased so
that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the close of business on such Record Date by a fraction, 

        (i)    the
numerator of which shall be the Current Market Price on such Record Date; and 

        (ii)   the
denominator of which shall be the Current Market Price on such Record Date less the amount of cash so distributed (and not excluded as provided above) applicable to
one share of Common Stock, 

such
adjustment to be effective immediately prior to the opening of business on the day following the record date; provided that if the portion of the
cash so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price on the Record Date, in lieu of the foregoing adjustment, adequate provision shall be
made so that each Noteholder shall have the right to receive upon conversion the amount of cash such holder would have received had such holder converted each Note on the Record Date. If such dividend
or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. If
any adjustment is required to be made as set forth in this Section 16.05(e) as a result of a distribution that is a quarterly dividend, such adjustment shall be based upon the amount by which
such distribution exceeds the amount of the quarterly cash dividend permitted to be excluded pursuant hereto. If an adjustment is required to be made as set forth in this Section 16.05(e) above
as a result of a distribution that is not a quarterly dividend, such adjustment shall be based upon the full amount of the distribution. 

        (f)    In
case a tender or exchange offer made by the Company or any Subsidiary for all or any portion of the Common Stock shall expire and such tender or exchange offer (as
amended upon the expiration thereof) shall require the payment to stockholders of consideration per share of 

51

 

Common
Stock having a Fair Market Value (as determined by the Board of Directors, whose determination shall be conclusive, and described in a resolution of the Board of Directors) that as of the last
time (the "Expiration Time") tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended) exceeds the Closing Sale
Price of a share of Common Stock on the Trading Day next succeeding the Expiration Time, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the
Conversion Rate in effect immediately prior to the Expiration Time by a fraction, 

        (i)    the
numerator of which shall be the sum of (x) the Fair Market Value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the
acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged and not withdrawn as of the Expiration Time (the shares deemed so
accepted up to any such maximum,
being referred to as the "Purchased Shares") and (y) the product of the number of shares of Common Stock outstanding (less any Purchased Shares)
at the Expiration Time and the Closing Sale Price of a share of Common Stock on the Trading Day next succeeding the Expiration Time, and 

        (ii)   the
denominator of which shall be the number of shares of Common Stock outstanding (including any tendered or exchanged shares) at the Expiration Time multiplied by the
Closing Sale Price of a share of Common Stock on the Trading Day next succeeding the Expiration Time, 

such
adjustment to become effective immediately prior to the opening of business on the day following the Expiration Time. If the Company is obligated to purchase shares pursuant to any such tender or
exchange offer, but the Company is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Rate shall again be adjusted to be the
Conversion Rate that would then be in effect if such tender or exchange offer had not been made. 

        (g)   For
purposes of this Section 16.05, the following terms shall have the meaning indicated: 

        (i)    "Current Market Price" shall mean the average of the daily Closing Sale Prices per share of Common Stock for the ten
consecutive Trading Days ending on the earlier of such date of determination and the day before the "ex" date with respect to the issuance,
distribution, subdivision or combination requiring such computation immediately prior to the date in question. For purpose of this clause (i), the term
"ex" date, (1) when used with respect to any issuance or distribution, means the first date on which the Common Stock trades, regular way, on the
relevant exchange or in the relevant market from which the Closing Sale Price was obtained without the right to receive such issuance or distribution, and (2) when used with respect to any
subdivision or combination of shares of Common Stock, means the first date on which the Common Stock trades, regular way, on such exchange or in such market after the time at which such subdivision or
combination becomes effective. 

        If
another issuance, distribution, subdivision or combination to which Section 16.05 applies occurs during the period applicable for calculating "Current
Market Price" pursuant to the definition in the preceding paragraph, "Current Market Price" shall be calculated for such period
in a manner determined by the Board of Directors to reflect the impact of such issuance, distribution, subdivision or combination on the Closing Sale Price of the Common Stock during such period. 

        (ii)   "Fair Market Value" shall mean the amount which a willing buyer would pay a willing seller in an arm's-length
transaction. 

        (iii)  "Record Date" shall mean, with respect to any dividend, distribution or other transaction or event in which the holders
of Common Stock have the right to receive any cash, 

52

 

securities
or other property or in which the Common Stock (or other applicable security) is exchanged for or converted into any combination of cash, securities or other property, the date fixed for
determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise). 

        (iv)  "Trading Day" shall mean (x) if the applicable security is quoted on the Nasdaq National Market, a day on which
trades may be made thereon or (y) if the applicable security is listed or admitted for trading on the New York Stock Exchange or another national securities exchange, a day on which the New
York Stock Exchange or another national securities exchange is open for business or (z) if the applicable security is not so listed, admitted for trading or quoted, any day other than a
Saturday or Sunday or a day on which banking institutions in the State of New York are authorized or obligated by law or executive order to close. 

        (h)   The
Company may make such increases in the Conversion Rate, in addition to those required by Section 16.05(a), (b), (c), (d), (e) or (f) as the
Board of Directors considers to be advisable to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock resulting from any dividend or distribution of stock (or
rights to acquire stock) or from any event treated as such for income tax purposes. 

        To
the extent permitted by applicable law, the Company from time to time may increase the Conversion Rate by any amount for any period of time if the period is at least twenty
(20) days, the increase is irrevocable during the period and the Board of Directors shall have made a determination that such increase would be in the best interests of the Company, which
determination shall be conclusive. Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Company shall mail to holders of record of the Notes a notice of the increase at
least fifteen (15) days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect. 

        (i)    No
adjustment in the Conversion Rate shall be required unless such adjustment would require an increase or decrease of at least one percent (1%) in such rate;  provided that any adjustments that by reason
of this Section 16.05(i) are not required to be made shall be carried forward and taken into
account in any subsequent adjustment. All calculations under this Article 16 shall be made by the Company and shall be made to the nearest cent or to the nearest one-ten thousandth
(1/10,000) of a share, as the case may be. No adjustment need be made for rights to purchase Common Stock pursuant to a Company plan for reinvestment of dividends or interest or for any issuance of
Common Stock or convertible or exchangeable securities or rights to purchase Common Stock or convertible or exchangeable securities. To the extent the Notes become convertible into cash, assets,
property or securities (other than capital stock of the Company), no adjustment need be made
thereafter as to the cash, assets, property or such securities. Interest will not accrue on any cash into which the Notes are convertible. 

        (j)    Whenever
the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee and any conversion agent other than the Trustee an
Officers' Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the
Trustee shall have received such Officers' Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume that the last Conversion Rate of which
it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion
Rate and the date on which each adjustment becomes effective and shall mail 

53

 

such
notice of such adjustment of the Conversion Rate to the holder of each Note at his last address appearing on the Note Register provided for in Section 2.05 of this Indenture, within twenty
(20) days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of any such adjustment. 

        (k)   In
any case in which this Section 16.05 provides that an adjustment shall become effective immediately after (1) a Record Date for an event, (2) the
date fixed for the determination of stockholders entitled to receive a dividend or distribution pursuant to Section 16.05(a), (3) a date fixed for the determination of stockholders
entitled to receive rights or warrants pursuant to Section 16.05(b) or (4) the Expiration Time for any tender or exchange offer pursuant to Section 16.05(f) (each a
"Determination Date"), the Company may elect to defer until the occurrence of the applicable Adjustment Event (as hereinafter defined)
(x) issuing to the holder of any Note converted after such Determination Date and before the occurrence of such Adjustment Event, the additional shares of Common Stock or other securities
issuable upon such conversion by reason of the adjustment required by such Adjustment Event over and above the Common Stock issuable upon such conversion before giving effect to such adjustment and
(y) paying to such holder any amount in cash in lieu of any fraction pursuant to Section 16.03. For purposes of this Section 16.05(k), the term "Adjustment
Event" shall mean: 

        (i)    in
any case referred to in clause (1) hereof, the occurrence of such event, 

        (ii)   in
any case referred to in clause (2) hereof, the date any such dividend or distribution is paid or made, 

        (iii)  in
any case referred to in clause (3) hereof, the date of expiration of such rights or warrants, and 

        (iv)  in
any case referred to in clause (4) or clause (5) hereof, the date a sale or exchange of Common Stock pursuant to such tender or exchange offer is
consummated and becomes irrevocable. 

        (l)    For
purposes of this Section 16.05, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but
shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company will not pay any dividend or make any distribution on shares of Common
Stock held in the treasury of the Company. 

        Section 16.06.    Effect Of Reclassification, Consolidation, Merger or Sale.    If any of the following events
occur, namely (i) any reclassification or change of the outstanding shares of Common Stock (other than a subdivision or combination to which Section 16.05(c) applies), (ii) any
consolidation, merger or combination of the Company with another Person as a result of which holders of Common Stock shall be entitled to receive stock, other securities or other property or assets
(including cash) with respect to or in exchange for such Common Stock, or (iii) any sale or conveyance of all or substantially all of the properties and assets of the Company to any other
Person as a result of which holders of Common Stock shall be entitled to receive stock, other securities or other property or assets (including cash) with respect to or in exchange for such Common
Stock, then the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force
at the date of execution of such supplemental indenture) providing that each Note shall be convertible into the kind and amount of shares of stock, other securities or other property or assets
(including cash) receivable upon such reclassification, change, consolidation, merger, combination, sale or conveyance by a holder of a number of shares of Common Stock issuable upon conversion of
such Notes (assuming, for such purposes, a sufficient number of authorized shares of Common Stock are available to convert all such Notes) immediately prior to such reclassification, change,
consolidation, merger, combination, sale or conveyance assuming 

54

 

such
holder of Common Stock did not exercise his rights of election, if any, as to the kind or amount of stock, other securities or other property or assets (including cash) receivable upon such
reclassification, change, consolidation, merger, combination, sale or conveyance (provided that, if the kind or amount of stock, other securities or
other property or assets (including cash) receivable upon such reclassification, change, consolidation, merger, combination, sale or conveyance is not the same for each share of Common Stock in
respect of which such rights of election shall not have been exercised ("non-electing share"), then for the purposes of this Section 16.06 the kind and amount of stock, other
securities or other property or assets (including cash) receivable upon such reclassification, change, consolidation, merger, combination, sale or conveyance for each non-electing share
shall be deemed to be the kind and amount so receivable per share by a plurality of the non-electing shares). Such supplemental indenture shall provide for adjustments which shall be as
nearly equivalent as may be practicable to the adjustments provided for in this Article 16. 

        The
Company shall cause notice of the execution of such supplemental indenture to be mailed to each holder of Notes, at its address appearing on the Note Register provided for in
Section 2.05 of this Indenture, within twenty (20) days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. 

        The
above provisions of this Section shall similarly apply to successive reclassifications, changes, consolidations, mergers, combinations, sales and conveyances. 

        If
this Section 16.06 applies to any event or occurrence, Section 16.05 shall not apply. 

        Section 16.07.    Taxes On Shares Issued.    The issue of stock certificates on conversions of Notes shall be
made without charge to the converting Noteholder for any documentary, stamp or similar issue or transfer tax in respect of the issue thereof. The Company shall not, however, be required to pay any
such tax which may be payable in respect of any transfer involved in the issue and delivery of stock in any name other than that of the holder of any Note converted, and the Company shall not be
required to issue or deliver any such stock certificate unless and until the Person or Persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have
established to the satisfaction of the Company that such tax has been paid. 

        Section 16.08.    Reservation of Shares, Shares to Be Fully Paid; Compliance With Governmental
Requirements; Listing of Common Stock.    The Company shall provide, free from preemptive rights, out of its
authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for the conversion of the Notes from time to time as such Notes are presented for conversion
unless the Company delivers cash in lieu of shares of Common Stock pursuant to Section 16.12. From time to time as additional shares of Common Stock become available, the Company shall reserve
additional shares of Common Stock out of its authorized but unissued shares or shares held in treasury until the Company has reserved a sufficient number of shares of Common Stock to deliver from time
to time as such Notes are presented for conversion. 

        Before
taking any action which would cause an adjustment increasing the Conversion Rate to an amount that would cause the Conversion Price to be reduced below the then par value, if any,
of the shares of Common Stock issuable upon conversion of the Notes, the Company will take all corporate action which may, in the opinion of its counsel, be necessary in order that the Company may
validly and legally issue shares of such Common Stock at such adjusted Conversion Rate. 

        The
Company covenants that all shares of Common Stock which may be issued upon conversion of Notes will upon issue be fully paid and non-assessable by the Company and free
from all taxes, liens and charges with respect to the issue thereof. 

        The
Company covenants that, subject to the registration statement filing and effectiveness periods set out in the Registration Rights Agreement, if any shares of Common Stock to be
provided for the purpose of conversion of Notes hereunder require registration with or approval of any governmental 

55

 

authority
under any federal or state law before such shares may be validly issued upon conversion, the Company will in good faith and as expeditiously as possible, to the extent then permitted by the
rules and interpretations of the Commission (or any successor thereto), endeavor to secure such registration or approval, as the case may be. 

        The
Company further covenants that, subject to the provisions of the Registration Rights Agreement, if at any time the Common Stock shall be listed on the Nasdaq National Market or any
other national securities exchange or automated quotation system, the Company will, if permitted by the rules of such exchange or automated quotation system, list and keep listed, so long as the
Common Stock shall be so listed on such exchange or automated quotation system, all Common Stock issuable upon conversion of the Note; provided that if
the rules of such exchange or automated quotation system permit the Company to defer the listing of such Common Stock until the first conversion of the Notes into Common Stock in accordance with the
provisions of this Indenture, the Company covenants to list such Common Stock issuable upon conversion of the Notes in accordance with the requirements of such exchange or automated quotation system
at such time. 

        Subject
to the conditions set forth in Section 16.12, if the Company timely elects to pay cash in lieu of all or any portion of the shares of Common Stock otherwise issuable to
the Holder, the above provisions of this Section 16.08 shall not apply to the portion of the conversion obligation paid in cash. 

        Section 16.09.    Responsibility Of Trustee.    The Trustee and any other conversion agent shall not at any
time be under any duty or responsibility to any holder of Notes to determine the Conversion Rate or whether any facts exist which may require any adjustment of the Conversion Rate, or with respect to
the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same.
The Trustee and any other conversion agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities or property, which
may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any other conversion agent make no representations with respect thereto. Neither the Trustee nor any
conversion agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the
surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 16. Without limiting the
generality of the foregoing, neither the Trustee nor any conversion agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture
entered into pursuant to Section 16.06 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Noteholders upon the conversion of their
Notes after any event referred to in such Section 16.06 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 9.01, may accept as conclusive
evidence of the correctness of any such provisions, and shall be protected in
relying upon, the Officers' Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. 

        Section 16.10.    Notice To Holders Prior To Certain Actions.    In case: 

        (a)   the
Company shall declare a dividend (or any other distribution) on its Common Stock that would require an adjustment in the Conversion Rate pursuant to
Section 16.05; or 

        (b)   the
Company shall authorize the granting to the holders of all or substantially all of its Common Stock of rights or warrants to subscribe for or purchase any share of
any class or any other rights or warrants; or 

        (c)   of
any reclassification or reorganization of the Common Stock of the Company (other than a subdivision or combination of its outstanding Common Stock, or a change in par
value, or from par value to no par value, or from no par value to par value), or of any consolidation or 

56

 

merger
to which the Company is a party and for which approval of any stockholders of the Company is required, or of the sale or transfer of all or substantially all of the assets of the Company; or 

        (d)   of
the voluntary or involuntary dissolution, liquidation or winding up of the Company; 

the
Company shall cause to be filed with the Trustee and to be mailed to each holder of Notes at his address appearing on the Note Register provided for in Section 2.05 of this Indenture, as
promptly as reasonably possible but in any event at least ten (10) days prior to the applicable date hereinafter specified, a notice stating (x) the date on which a record is to be taken
for the purpose of such dividend, distribution or rights or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend,
distribution or rights are to be determined, or (y) the date on which such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up is expected to become
effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon
such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of
such dividend, distribution, reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up. 

        Section 16.11.    Stockholder Rights Plans.    If the rights provided for in the Company's Rights Agreement
dated July 17, 2001, as amended, or in any future rights plan adopted by the Company have separated from the shares of Common Stock in accordance with the provisions of the applicable
stockholder rights agreement so that the holders of the Notes would not be entitled to receive any rights in respect of Common Stock issuable upon conversion of the Notes, the Conversion Rate will be
adjusted as provided in Section 16.05(d). 

        Section 16.12.    Cash Conversion Option.    

        (a)   In
the event that, on or prior to the date that is five days prior to the stated maturity of a Note (the "Final Notice
Date"), a Holder elects to convert all or any portion of a Note into shares of Common Stock as set forth in Section 16.01, the Company may choose to satisfy all or any
portion of its conversion obligation (the "Conversion Obligation") in cash if the Company notifies such Holder through the Trustee at any time on or
before the date that is two Business Days following receipt of written notice of conversion as specified in Section 16.02 (such period, the "Cash Settlement Notice
Period") of the dollar amount to be satisfied in cash. If the Company timely elects to pay cash in lieu of all or any portion of the shares of Common Stock otherwise issuable
to the Holder, the Holder may retract the conversion notice at any time during the two Business Day period beginning on the day after the final day of the Cash Settlement Notice Period (a
"Conversion Retraction Period"); no such retraction may be made (and a conversion notice shall be irrevocable) if the Company does not elect to deliver
cash in lieu of all or any portion of the shares (other than cash in lieu of fractional shares). If the conversion notice has not been retracted, then cash settlement or combined settlement (in a
combination of cash and shares of Common Stock) will occur on the Business Day following the final Trading Day of the five Trading Day period beginning on the first Trading Day after the final day of
the Conversion Retraction Period (the "Cash Settlement Averaging Period"). Settlement amounts will be computed as follows: 

        (i)    if
the Company elects to satisfy the Conversion Obligation in shares of Common Stock, the Company will deliver to such Holder a number of shares of Common Stock equal to
the quotient of the aggregate original principal amount of the Notes to be converted divided by the Conversion Price then in effect; 

57

 

        (ii)   if
the Company elects to satisfy the Conversion Obligation in cash, the Company will deliver to such Holder cash in an amount equal to the product of: 

        (A)  a
number equal to the quotient of the aggregate original principal amount of Notes to be converted divided by the Conversion Price then in effect, and 

        (B)  the
average Closing Sale Price of the Common Stock during the Cash Settlement Averaging Period; 

        (iii)  if
the Company elects to satisfy a portion of the Conversion Obligation in cash (the "Partial Cash Amount") and a
portion of the Conversion Obligation in shares of Common Stock, the Company will deliver to such Holder cash in an amount equal to the Partial Cash Amount and a number of shares of Common Stock equal
to the quotient of (A) the excess of: (1) the product of (x) a number equal to the quotient of the aggregate original principal amount of Notes to be converted divided by the
Conversion Price then in effect and (y) the average Closing Sale Price of the Common Stock during the Cash Settlement Averaging Period, over (2) the Partial Cash Amount; divided by
(B) the average Closing Sale Price of the Common Stock during the Cash Settlement Averaging Period. 

        Notwithstanding
the foregoing, a Note in respect of which a Holder has delivered a Repurchase Notice or a Designated Event Repurchase Notice exercising such Holder's option to require
the Company to repurchase such Note may be converted as described in this Article 16 only if such notice of exercise is withdrawn in accordance with the terms of Article 3 hereof. 

        (b)   If
a Holder elects to convert all or any portion of a Security into shares of Common Stock after the Final Notice Date, the Company may choose to satisfy all or any
portion of the Conversion Obligation in cash provided that the Company notifies such Holder through the Trustee of the cash settlement or combined settlement, including the percentage of any combined
settlement to be satisfied in cash, at any time on or before the final day of the Cash Settlement Notice Period. Settlement amounts will be computed and settlement dates will be determined in the same
manner as set forth in (a) above except that the Cash Settlement Averaging Period shall be the five Trading Day period beginning on the first Trading Day after the Conversion Retraction Period.
If the Company timely elects to pay cash in lieu of all or any portion of the shares of Common Stock otherwise issuable to the Holder, the Holder may retract the Conversion Notice at any time during
the Conversion Retraction Period; no such retraction may be made (and a conversion notice shall be irrevocable) if the Company does not elect to deliver cash in lieu of all or any portion of the
shares (other than cash in lieu of fractional shares). If the conversion notice has not been retracted, then cash settlement or combined settlement (in a combination of cash and shares of Common
Stock) will occur on the Business Day following the final day of such Cash Settlement Averaging Period, and, with respect to the Notes subject to such conversion, such Business Day shall constitute
the final Maturity Date (notwithstanding anything herein to the contrary).

shall give to any Person, other than the parties hereto, any paying agent, any authenticating agent, any Note Registrar and their successors hereunder and the holders of Notes any benefit or any legal
or equitable right, remedy or claim under this Indenture. 

        Section 17.10.    Table Of Contents, Headings, Etc.    The table of contents and the titles and headings of the
Articles and Sections of this Indenture have been inserted for convenience of reference only, are not to be considered a part hereof, and shall in no way modify or restrict any of the terms or
provisions hereof. 

        Section 17.11.    Authenticating Agent.    The Trustee may appoint an authenticating agent that shall be
authorized to act on its behalf, and subject to its direction, in the authentication and delivery of Notes in connection with the original issuance thereof and transfers and exchanges of Notes
hereunder, including under Sections 2.04, 2.05, 2.06, 2.07 and 3.05, as fully to all intents and purposes as though the authenticating agent had been expressly authorized by this Indenture and those
Sections to authenticate and deliver Notes. For all purposes of this Indenture, the authentication and delivery of Notes by the authenticating agent shall be deemed to be authentication and delivery
of such Notes "by the Trustee" and a certificate of authentication executed on behalf of the Trustee by an authenticating agent shall be deemed to satisfy any requirement hereunder or in the Notes for
the Trustee's certificate of authentication. Such authenticating agent shall at all times be a Person eligible to serve as trustee hereunder pursuant to Section 9.09. 

        Any
corporation into which any authenticating agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, consolidation or
conversion to which any authenticating agent shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of any authenticating agent, shall be the
successor of the authenticating agent hereunder, if such successor corporation is otherwise eligible under this Section 17.11, without the execution or filing of any paper or any further act on
the part of the parties hereto or the authenticating agent or such successor corporation. 

        Any
authenticating agent may at any time resign by giving written notice of resignation to the Trustee and to the Company. The Trustee may at any time terminate the agency of any
authenticating agent by giving written notice of termination to such authenticating agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any
time any authenticating agent shall cease to be eligible under this Section, the Trustee shall either promptly appoint a successor authenticating agent or itself assume the duties and obligations of
the former authenticating agent under this Indenture and, upon such appointment of a successor authenticating agent, if made, shall give written notice of such appointment of a successor
authenticating agent to the Company and shall mail notice of such appointment of a successor authenticating agent to all holders of Notes as the names and addresses of such holders appear on the Note
Register. 

60

 

        The
Company agrees to pay to the authenticating agent from time to time such reasonable compensation for its services as shall be agreed upon in writing between the Company and the
authenticating agent. 

        The
provisions of Sections 9.02, 9.03, 9.04 and 10.03 and this Section 17.11 shall be applicable to any authenticating agent. 

        Section 17.12.    Execution In Counterparts.    This Indenture may be executed in any number of counterparts,
each of which shall be an original, but such counterparts shall together constitute but one and the same instrument. 

        Section 17.13.    Severability.    In case any provision in this Indenture or in the Notes shall be invalid,
illegal or unenforceable, then (to the extent permitted by law) the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 

        The
Trustee hereby accepts the trusts in this Indenture declared and provided, upon the terms and conditions herein above set forth.

        IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed.

FORM OF REVERSE OF NOTE  

 INTERMUNE, INC.  

 .25% CONVERTIBLE SENIOR NOTE DUE 2011  

        This Note is one of a duly authorized issue of Notes of the Company, designated as its .25% Convertible Senior Notes Due 2011 (herein called the
"Notes"), limited in aggregate principal amount to $150,000,000 (or if the Company sells an additional $20,000,000 principal amount of its Notes
pursuant to the option of the Initial Purchasers granted pursuant to the Purchase Agreement dated as of February 10, 2004 between the Company and the Initial Purchasers, limited in the
aggregate principal amount to $170,000,000), issued and to be issued under and pursuant to an Indenture dated as of February 17, 2004 (herein called the
"Indenture"), between the Company and The Bank of New York, 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 Notes. 

        The
Notes are issuable in fully registered form, without coupons, in denominations of $1,000 principal amount and any multiple of $1,000. Upon due presentment for registration of
transfer of this Note at the office or agency of the Company maintained for that purpose in accordance with the terms of the Indenture, a new Note or Notes 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
Notes are not subject to redemption through the operation of any sinking fund and may not be redeemed at the option of the Company prior to maturity. 

        If
a Designated Event occurs at any time prior to maturity of the Notes, this Note will be redeemable at the option of the holder of this Note at a redemption price equal to 100% of the
principal amount hereof, together with accrued interest and Liquidated Damages, if any to (but excluding) the redemption date, as provided in Article 3 of the Indenture. 

        At
the Company's option (subject to the conditions set forth in the Indenture), pursuant to the provisions of Section 3.06 of the Indenture, the Company may, upon the occurrence
of a Designated Event, pay the redemption price in the Company's Common Stock (or that of the Company's parent, if applicable) or a combination of cash and the applicable common stock. 

        Subject
to compliance with the provisions of the Indenture, prior to the close of business on the final maturity date of the Notes, the holder hereof has the right, at its option, to
convert each $1,000 principal amount of this Note into 46.2283 shares (the "Conversion Rate") of the Company's Common Stock, as such shares shall be
constituted at the date of conversion and subject to adjustment from time to time as provided in the Indenture. Upon conversion, the Company may choose to deliver either cash in lieu of shares of the
Company's Common Stock, shares of the Company's Common Stock or a combination of cash and shares of the Company's Common Stock, as provided in Section 16.12 of the Indenture. 

        Except
to the extent the Company elects to pay all or a portion of a conversion by cash payment, no adjustment in respect of interest on any Note converted or dividends on any shares
issued upon conversion of such Note will be made upon any conversion except as set forth in the next sentence. If this Note (or portion hereof) is surrendered for conversion during the period from the
close of business on any record date for the payment of interest to the close of business on the Business Day preceding the following interest payment date, this Note (or portion hereof being
converted) must be accompanied by payment, in immediately available funds or other funds acceptable to the Company, of an amount equal to the interest otherwise payable on such interest payment date
on the principal 

A-5

 

amount
being converted; provided that no such payment shall be required (1) if the Company has specified a redemption date following a Designated
Event that is after a record date and on or prior to the next interest payment date or (2) to the extent of any overdue interest at the time of conversion with respect to this Note. 

        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 Note or Notes for conversion. 

        A
Note in respect of which a holder is exercising its right to require redemption upon a Designated Event may be converted only if such holder withdraws its Redemption Notice in
accordance with the terms of the Indenture. 

        In
case an Event of Default shall have occurred and be continuing, the principal of, premium, if any, and accrued interest, on all Notes may be declared by either the Trustee or the
holders of not less than 25% in aggregate principal amount of the Notes then outstanding, and upon said declaration shall become, 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 at least a majority in aggregate principal amount of the Notes 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 Notes, subject to the exceptions set forth in Section 12.02 of the Indenture. Subject to the provisions of the Indenture, the holders of a
majority in aggregate principal amount of the Notes at the time outstanding may on behalf of the holders of all of the Notes waive any past, current or future breach of any provision of the Indenture,
default or Event of Default, in each case subject to the exceptions set forth in the Indenture. Any such consent or waiver by the holder of this Note (unless revoked as provided in the Indenture)
shall be conclusive and binding upon such holder and upon all future holders and owners of this Note and any Notes which may be issued in exchange or substitution hereof, irrespective of whether or
not any notation thereof is made upon this Note or such other Notes. 

        No
reference herein to the Indenture and no provision of this Note 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, on this Note at the place, at the respective times, at the rate and in the coin or currency herein prescribed. 

        The
Company, the Trustee, any authenticating agent, any paying agent, any conversion agent and any Note Registrar may deem and treat the registered holder hereof as the absolute owner of
this Note (whether or not this Note shall be overdue and notwithstanding any notation of ownership or other writing hereon made by anyone other than the Company or any Note 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 Note 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 Note. 

        No
recourse for the payment of the principal of or any premium or interest on this Note, 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 Note, 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. 

        Terms
used in this Note and defined in the Indenture are used herein as therein defined.
