RIGHTS ATTACHING TO THIS REGULATION S TEMPORARY GLOBAL NOTE, AND THE CONDITIONS AND PROCEDURES GOVERNING ITS EXCHANGE FOR CERTIFICATED NOTES, ARE AS SPECIFIED IN THE INDENTURE (AS DEFINED
HEREIN)." 

SECTION 2.02.    Denominations  

        The Notes shall be in minimum denominations of $2,000 aggregate principal amount and integral multiples of $1,000 in excess thereof;  provided, however, that Additional PIK Notes shall be issued in denominations of $1.00 and integral multiples of $1.00.
 

SECTION 2.03.    Execution and Authentication  

        The aggregate principal amount of Notes that may be authenticated and delivered under this Indenture is unlimited. The Trustee shall, upon a written order of the
Company signed by two Officers of the Company or by an Officer and an Assistant Treasurer or an Assistant Secretary of the Company (an "Authentication
Order"), authenticate (i) on the Issue Date, the Initial Notes in aggregate principal amount of $55.0 million, (ii) subject to the provisions of
Section 2.15, at any time and from time to time after July 31, 2005, Additional PIK Notes as payment for accrued interest on the Notes or Additional Interest, as specified in such
authentication order, (iii) subject to the provisions of Section 2.16, at any time and from time to time thereafter, Additional Notes in an aggregate principal amount specified in such
authentication order and (iv) subject to the provisions of Section 2.07(f), Exchange Notes issued in exchange for a like principal amount of Initial Notes, Additional PIK Notes or

Notes pursuant to Section 2.07, 2.08, 2.11 or 9.05 or in connection with a Change of Control Offer pursuant to Section 4.15. 

        An
Officer of the Company shall sign the Notes for the Company by manual or facsimile signature. If an Officer whose signature is on a Note no longer holds that office at the time a Note
is authenticated, the Note shall nevertheless be valid. 

        A
Note shall not be valid until an authorized signatory of the Trustee manually authenticates the Note. The signature of the Trustee on a Note shall be conclusive evidence that the Note
has been duly and validly authenticated and issued under this Indenture. 

        The
Trustee may appoint an authenticating agent (the "Authenticating Agent") acceptable to the Company to authenticate Notes. An
Authenticating Agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such Authenticating Agent. An
Authenticating Agent has the same rights as an Agent to deal with Holders or an Affiliate of the Company. 

25

 

SECTION 2.04.    Registrar and Paying Agent  

        The Company shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange
("Registrar") and an office or agency where Notes may be presented for payment ("Paying Agent"). The
Company shall cause each of the Registrar and the Paying Agent to maintain an office or agency in the Borough of Manhattan, The City of New York. The Registrar shall keep a register of the Notes and
of their transfer and exchange. The Company may appoint one or more co-registrars and one or more additional paying agents. The term "Registrar" includes any co-registrar and
the term "Paying Agent" includes any additional paying agent. 

        The
Company shall enter into an appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture, which shall incorporate the terms of the TIA. The agreement
shall implement the provisions of this Indenture that relate to such agent. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company shall notify the Trustee in
writing of the name and address of any Agent not a party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The
Company or any of its Subsidiaries may act as Paying Agent or Registrar. The Company initially appoints the Trustee to act as the Registrar and Paying Agent. 

SECTION 2.05.    Paying Agent to Hold Money in Trust  

        Subject to Section 2.14 hereof, by no later than 11:00 a.m. (New York City time) on the date on which any principal of, premium or Additional
Interest, if any, or interest on any Notes is due and payable, the Company shall deposit with the Paying Agent a sum sufficient in immediately available funds to pay such amount when due. The Company
shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for
the payment of principal of, premium or Additional Interest, if any, or interest on the Notes, and shall notify the Trustee in writing of any default by the Company in making any such payment. While
any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all
money held by it to the Trustee and to account for any funds disbursed by such Paying Agent. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary) shall have
no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as
Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee shall serve as Paying Agent for the Notes. 

SECTION 2.06.    Holder Lists  

        The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders and
shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, the Company shall furnish to the Trustee at least five Business Days before each interest payment date and at
such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes and the Company
shall otherwise comply with TIA § 312(a). 

SECTION 2.07.    Transfer and Exchange  

        (a)   Transfer and Exchange of Global Notes. A Global Note may not be transferred as a whole except by the Depositary to a
nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of
such successor Depositary. All Global Notes shall be exchanged by the Company for Definitive Notes if (i) the Company delivers to the Trustee notice from the 

26

 

Depositary
that it is unwilling or unable to continue to act as Depositary or that it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is
not appointed by the Company within 120 days after the date of such notice from the Depositary, (ii) the Company in its sole discretion determines that the Global Notes (in whole but not
in part) should be exchanged for Definitive Notes and delivers a written notice to such effect to the Trustee; or (iii) there shall have occurred and be continuing a Default or Event of Default
with respect to the Notes; provided that in no event shall the Regulation S Temporary Global Note be exchanged by the Company for Definitive
Notes prior to (x) the expiration of the Distribution Compliance Period and (y) the receipt by the Registrar of any certificates required pursuant to Rule 903(c)(3)(ii)(B) under
the Securities Act. Upon the occurrence of any of the preceding events in (i), (ii) or (iii) above, Definitive Notes shall be issued in such names as the Depositary shall instruct the
Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.08, 2.11 and 9.05 hereof. Every Note authenticated and delivered in exchange for, or in lieu of,
a Global Note or any portion thereof, pursuant to this Section 2.07 or Section 2.08 or 2.11 or 9.05 hereof, shall be authenticated and delivered in the form of, and shall be, a Global
Note. A Global Note may not be exchanged for another Note other than as provided in this Section 2.07(a); however, beneficial interests in a Global Note may be transferred and exchanged as
provided in Section 2.07(b), (c) or (f) hereof. 

        (b)   Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in
the Global Notes shall be effected through the Depositary, in accordance with the provisions of this Indenture and the Applicable Procedures. Beneficial interests in the Restricted Global Notes shall
be subject to restrictions on transfer comparable to those set forth herein to the extent required by the Securities Act. Transfers of beneficial interests in the Global Notes also shall require
compliance with either subparagraph (i) or (ii) below, as applicable, as well as one or more of the other following subparagraphs, as applicable: 

        (i)    Transfer of Beneficial Interests in the Same Global Note. Beneficial interests in any Restricted Global Note may be
transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Restricted Global Note in accordance with the transfer restrictions set forth in the Private Placement
Legend and any Applicable Procedures; provided, however, that prior to the expiration of the
Distribution Compliance Period, transfers of beneficial interests in the Temporary Regulation S Global Note may not be made to a U.S. Person or for the account or benefit of a U.S. Person
(other than an Initial Purchaser or a "distributor" (as defined in Rule 902(d) of Regulation S)). Beneficial interests in any Unrestricted Global Note may be transferred to Persons who
take delivery thereof in the form of a beneficial interest in an Unrestricted Global Note. Except as may be required by Applicable Procedures, no written orders or instructions shall be required to be
delivered to the Registrar to effect the transfers described in this Section 2.07(b)(i). 

        (ii)   All Other Transfers and Exchanges of Beneficial Interests in Global Notes. In connection with all transfers and
exchanges of beneficial interests that are not subject to Section 2.07(b)(i) above, the transferor of such beneficial interest must deliver to the Registrar either (A) (1) a
written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to credit or cause to be credited a beneficial
interest in another Global Note in an amount equal to the beneficial interest to be transferred or exchanged and (2) instructions given in accordance with the Applicable Procedures containing
information regarding the Participant account to be credited with such increase or (B) if permitted under Section 2.07(a) hereof, (1) a written order from a Participant or an

to be transferred or exchanged and (2) instructions given by the Depositary to the Registrar containing information regarding the Person in whose name such Definitive Note 

27

 

shall
be registered to effect the transfer or exchange referred to in (B)(1) above; provided that in no event shall Definitive Notes be issued upon the
transfer or exchange of beneficial interests in the Regulation S Temporary Global Note prior to (x) the expiration of the Distribution Compliance Period and (y) the receipt by the
Registrar of any certificates required pursuant to Rule 903 under the Securities Act. Upon consummation of an Exchange Offer by the Company in accordance with Section 2.07(f) hereof, the
requirements of this Section 2.07(b)(ii) shall be deemed to have been satisfied upon receipt by the Registrar of the instructions contained in the Letter of Transmittal delivered by the
Holder of such beneficial interests in the Restricted Global Notes. Upon notification from the Registrar that all of the requirements for transfer or exchange of beneficial interests in Global Notes
contained in this Indenture and the Notes or otherwise applicable under the Securities Act have been satisfied, the Trustee shall adjust the principal amount of the relevant Global Note(s) pursuant to
Section 2.07(h) hereof. 

        (iii)  Transfer of Beneficial Interests in a Restricted Global Note to Another Restricted Global Note. A beneficial interest
in any Restricted Global Note may be transferred to a Person who takes delivery thereof in the form of a beneficial interest in another Restricted Global Note if the transfer complies with the
requirements of Section 2.07(b)(ii) above and the Registrar and the Company receive the following: 

        (A)  if
the transferee shall take delivery in the form of a beneficial interest in the 144A Global Note, then the transferor must deliver a certificate in the form of

        (iv)  Transfer and Exchange of Beneficial Interests in a Restricted Global Note for Beneficial Interests in an Unrestricted Global
Note. A beneficial interest in any Restricted Global Note may be exchanged by any holder thereof for a beneficial interest in an Unrestricted Global Note or transferred to a
Person who takes delivery thereof in the form of a beneficial interest in an Unrestricted Global Note only if the exchange or transfer complies with the requirements of
Section 2.07(b)(ii) above and: 

        (A)  such
exchange or transfer is effected pursuant to an Exchange Offer in accordance with a Registration Rights Agreement and the holder of the beneficial interest to be

longer required in order to maintain compliance with the Securities Act. 

        If
any such transfer is effected pursuant to subparagraph (B) or (D) above at a time when an Unrestricted Global Note has not yet been issued, the Company shall issue and,
upon receipt of an Authentication Order in accordance with Section 2.03 hereof or in accordance with a previously delivered Authentication Order, the Trustee shall authenticate one or more

the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of
the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who shall take delivery thereof in the form of a beneficial interest in another
Global Note, such other Global Note shall be increased accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect

        (h)   General Provisions Relating to Transfers and Exchanges. 

        (i)    To
permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Global Notes and Definitive Notes upon the Company's
order. 

        (ii)   No
service charge shall be made to a holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange,
but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar
governmental charge payable upon exchange or transfer pursuant to Sections 2.11, 3.06, 4.10, 4.15 and 9.05 hereof). 

        (iii)  The
Registrar shall not be required to register the transfer of or to exchange any Note selected for redemption in whole or in part, except the unredeemed portion of
any Note being redeemed in part. 

        (iv)  All
Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes shall be the valid obligations of the
Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange. 

        (v)   The
Registrar shall not be required (A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business
15 days before the day of any selection of Notes for redemption under Section 3.02 hereof and ending at the close of business on the day of selection or (B) to register the
transfer of or to exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part. 

        (vi)  The
Trustee, any Agent and the Company may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of
receiving payment of principal of and interest on such Notes and for all other purposes, and none of the Trustee, any Agent or the Company shall be affected by notice to the contrary. 

        (vii) The
Trustee shall authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 2.03 hereof. 

35

 

        (viii) All
certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.07 to effect a registration of
transfer or exchange may be submitted by facsimile. 

        (ix)  The
Trustee is hereby authorized and directed to enter into a letter of representations with the Depositary in the form provided by the Company and to act in accordance
with such letter. 

        (x)   Subject
to compliance with any applicable additional requirements contained in this Article, when a Note is presented to the Registrar with a request to register a
transfer thereof or to exchange such Note for an equal principal amount of Notes of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested;  provided,
however, that every Note presented or surrendered for registration of transfer or exchange
shall be duly endorsed or accompanied by an assignment form and, if applicable, a transfer certificate, each in the form included in Exhibit A attached hereto and in form satisfactory to the
Registrar and each duly executed by the Holder thereof or its attorney duly authorized in writing. To permit registration of transfers and exchanges, upon surrender of any Note for registration of
transfer or exchange at an office or agency maintained for such purpose pursuant to Section 2.04, the Company shall execute, and the Trustee shall authenticate, Notes of a like aggregate
principal amount at the Registrar's request. 

        (xi)  Any
Registrar appointed pursuant to Section 2.04 shall provide to the Trustee such information as the Trustee may reasonably require in connection with the
delivery by such Registrar of Notes upon transfer or exchange of Notes. 

        (xii) The

applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Participants or other beneficial owners of interests in any Global Note) 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. 

        (xiii) None
of the Company, the Trustee or any Paying Agent shall have any responsibility or liability for any aspect of the records relating to, or payments made on account
of or transfers of, beneficial ownership interests in a Global Note or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 

        (xiv) None
of the Company, the Trustee or the Registrar shall have any liability for any acts or omissions of the Depositary, for any Depositary records of beneficial
interests, for any transaction between the Depositary or any Participant and/or beneficial owners, for any transfers of beneficial interests in the Notes, or in respect of any transfers effected by
the Depositary or by any Participant or any beneficial owner of any interest in any Notes held through any such Participant. 

36

   SECTION 2.08.    Mutilated, Destroyed, Lost or Stolen Notes  

        If any mutilated Note is surrendered to the Trustee or the Company and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any
Note, the Company shall issue and the Trustee, upon receipt of an Authentication Order or in accordance with a previously delivered Authentication Order, shall authenticate a replacement Note if the
Trustee's requirements are met. If required by the Trustee or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect
the Company, the Trustee, any Agent and any Authenticating Agent from any loss that any of them may suffer if a Note is replaced. The Company and the Trustee may charge for their expenses in replacing
a Note. 

        Every
replacement Note issued in accordance with this Section 2.08 is an additional obligation of the Company and any other obligor upon the Notes and shall be entitled to all of
the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder. 

        The
Company and the Trustee may charge the Holder for their expenses in replacing a Note. In the event any such mutilated, lost, destroyed or wrongfully taken Note has become or is about
to become due and payable, the Company in its discretion may pay such Note instead of issuing a new Note in replacement thereof. 

        The
provisions of this Section 2.08 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated,
lost, destroyed or wrongfully taken Notes. 

SECTION 2.09.    Outstanding Notes  

        The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those
reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section as not outstanding. Except as set forth in
Section 2.10 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note. 

        If
a Note is replaced pursuant to Section 2.08 hereof, it ceases to be outstanding unless the Company and the Trustee receive proof satisfactory to it that the replaced Note is
held by a bona fide purchaser. 

        If
the Paying Agent segregates and holds in trust, in accordance with this Indenture, by 11:00 a.m. New York City time, on a redemption date or other maturity date money
sufficient to pay all principal, premium and Additional Interest, if any, and interest payable on that date with respect to the Notes (or portions thereof) to be redeemed or maturing, as the case may
be, then on and after that date such Notes (or portions thereof) cease to be outstanding and interest on them ceases to accrue. 

SECTION 2.10.    Treasury Notes  

        In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company or by
any Affiliate of the Company shall be deemed not to be outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or
consent, only Notes that a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded. 

SECTION 2.11.    Temporary Notes  

        In the event that Definitive Notes are to be issued under the terms of this Indenture, until such Definitive Notes are ready for delivery, the Company may prepare
and the Trustee shall authenticate temporary Notes. Temporary Notes shall be substantially in the form, and shall carry all rights, of 

37

 

Definitive
Notes but may have variations that the Company considers appropriate for temporary Notes. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate Definitive
Notes. After the preparation of Definitive Notes, the temporary Notes shall be exchangeable for Definitive Notes upon surrender of the temporary Notes at any office or agency maintained by the Company
for that purpose and such exchange shall be without charge to the Holder. Upon surrender for cancellation of any one or more temporary Notes, the Company shall execute, and the Trustee shall
authenticate and make available for delivery in exchange therefor, one or more Definitive Notes representing an equal principal amount of Notes. Until so exchanged, the Holder of temporary Notes shall
in all respects be entitled to the same benefits under this Indenture as a Holder of Definitive Notes. 

SECTION 2.12.    Cancellation  

        The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Notes surrendered to
them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel and destroy all Notes surrendered for registration of transfer, exchange, payment, replacement or
cancellation in accordance with customary practices (subject to the record retention requirement of the Exchange Act) and, upon request, deliver a certificate of such destruction to the Company unless
the Company directs the Trustee to deliver canceled Notes to the Company. The Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for
cancellation. 

SECTION 2.13.    Defaulted Interest  

        If the Company defaults in a payment of interest on the Notes, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest
payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate and in the manner provided in the Notes and in Sections 2.14 and 4.01
hereof. 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. The Company shall fix or cause to be
fixed each such special record date and payment date; provided that no such special record date shall be less than 10 days prior to the related
payment date for such defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense
of the Company) shall mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. 

SECTION 2.14.    Computation and Payment of Interest  

        Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months. The Company, at its option, shall be
entitled to (i) pay accrued interest on the Notes in cash or (ii) issue Additional PIK Notes under this Indenture as payment for accrued interest on the Notes in lieu of the payment of
cash interest or Additional Interest. 

SECTION 2.15.    Issuance of Additional PIK Notes  

        (a)   The
Company shall be entitled to issue Additional PIK Notes under this Indenture which shall have identical terms as the Notes. The Initial Notes issued on the Issue
Date and any Additional PIK Notes shall be treated as a single class for all purposes under this Indenture. 

        (b)   Unless
otherwise agreed to between the Company and the Trustee, with respect to any Additional PIK Notes, the Company shall deliver to the Trustee and the Paying Agent: 

        (1)   no
later than the record date for the relevant interest payment date, a written notice setting forth the extent to which such interest payment will be made in the form
of cash, if an 

38

 

election
is made to pay in cash, and if no such election is made, such interest payment shall otherwise be payable in Additional PIK Notes; and 

        (2)   no
later than one Business Days prior to the relevant interest payment date, (i) if such securities are in definitive form, the required amount of new definitive
Additional PIK Notes and an order to authenticate and deliver such Additional PIK Notes or (ii) if such Notes are in global form, an order to increase the principal amount of such Notes by the
relevant amount (or, if necessary, to authenticate a new Global Notes executed by the Company with such increased principal amounts). 

        (c)   Any
Additional PIK Notes shall, after being executed and authenticated pursuant to Section 2.03 hereof, be (i) mailed to the person entitled thereto as
shown on the register for the Definitive Notes as of the relevant Record Date or (ii) deposited into the account specified by the Holder or Holders thereof as of the relevant Record Date if the
Notes are held in global form. Alternatively, the Company may direct the Paying Agent to make the appropriate amendments to the schedule of principal amounts of the relevant Global Notes outstanding
and arrange for deposit into the account specified by the Holder or Holders thereof as of the relevant Record Date. Payment shall be made in such form and upon such terms as specified herein and the
Company shall and Paying Agent may take additional steps as is necessary to effect such payment. 

        (d)   With
respect to any Additional PIK Notes issued after the Issue Date (except for Notes authenticated and delivered upon registration of transfer of, or in exchange for,
or in lieu of, other Notes pursuant to Sections 2.07, 2.08, 2.09, 2.11 and 3.06), the aggregate principal amount of such Additional PIK Notes which may be authenticated and delivered under this
Indenture shall be (i) established in or pursuant to a Board Resolution of the Company (provided that any such Board Resolution may authorize authentication of up to a maximum aggregate
principal amount from time to time without referring to aggregate principal amounts for specific interest periods) and (ii) set forth or determined in an Officers' Certificate of the Company.
If any of the terms of any Additional PIK Notes are established by action taken pursuant to a Board Resolution of the Company, a copy of an appropriate record of such action shall be certified by an
Officers' Certificate of the Company and delivered to the Trustee at or prior to the delivery of the Officers' Certificate of the Company in accordance with Section 2.15(d)(ii). 

SECTION 2.16.    Issuance of Additional Notes  

        The Company shall be entitled, subject to its compliance with Section 4.09, to issue Additional Notes under this Indenture which shall have identical terms
as the Initial Notes issued on the Issue Date or the Exchange Notes, other than with respect to the date of issuance and issue price, first payment of interest and rights under a related Registration
Rights Agreement, if any. 

        With
respect to any Additional Notes, the Company shall set forth in a resolution of the Board of Directors and an Officers' Certificate, a copy of each which shall be delivered to the
Trustee, the following information: 

        (a)   the
aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to this Indenture; 

        (b)   the
issue price, the issue date and the CUSIP number and corresponding ISIN of such Additional Notes; and 

        (c)   whether
such Additional Notes shall be Transfer Restricted Securities and issued in the form of Initial Notes as set forth in Exhibit A to this Indenture or shall
be issued in the form of Exchange Notes as set forth in Exhibit A to this Indenture. 

39

 

SECTION 2.17.    One Class of Notes

a single class for all purposes under this Indenture. 

SECTION 2.18.    CUSIP, ISIN or Other Similar Numbers  

        The Company in issuing the Notes may use "CUSIP," "ISIN" or other similar numbers (if then generally in use), and, if so, the Trustee shall use "CUSIP," "ISIN" or
other similar numbers in notices of redemption or offers to purchase as a convenience to Holders; 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 or offer to purchase and that reliance may be placed only on
the other identification numbers printed on the Notes, and any such redemption or offer to purchase shall not be affected by any defect in or omission of such numbers. The Company shall promptly
notify the Trustee of any change in the "CUSIP," "ISIN" or other similar numbers. 

ARTICLE 3

        The
Trustee shall promptly notify the Company in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof
to be redeemed. Notes and portions of Notes selected shall be in amounts of $1,000 or whole multiples of $1,000; except that if all of the Notes of a Holder are to be redeemed, the entire outstanding
amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for
redemption also apply to portions of Notes called for redemption.

        (h)   that
no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes. 

        At
the Company's request, the Trustee shall give the notice of redemption in the Company's name and at its expense; provided that the
Company shall have delivered to the Trustee, at least 35 days prior to the redemption date (unless a shorter period is acceptable to the Trustee), an Officers' Certificate requesting that the
Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph. 

SECTION 3.04.    Effect of Notice of Redemption  

        Once notice of redemption is mailed in accordance with Section 3.03 hereof, Notes called for redemption shall become irrevocably due and payable on the

the Company complies with the provisions of the preceding paragraph, on and after the redemption date, interest shall cease to accrue on the Notes or the portions of Notes called for
redemption. If a Note is redeemed on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose
name such Note was registered at the close of business on such record date. If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Company
to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption date until such principal is paid, and to the extent lawful on any interest not paid on such

unpaid
principal, in each case at the rate and in the manner provided in the Notes and in Sections 2.14 and 4.01 hereof.

become directly or indirectly liable, contingently or otherwise, with respect to (collectively, "incur") any Indebtedness (including Acquired Debt), and
the Company shall not issue any Disqualified Stock and shall not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided,
however, that (i) the Company may incur Indebtedness (including Acquired Debt) and the Company may issue Disqualified Stock if the Fixed Charge Coverage Ratio for the
Company's most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such
Disqualified Stock is issued would have been at least 2.0 to 1.0, and (ii) K&F Industries and any of its Domestic Subsidiaries may incur Indebtedness (including Acquired Debt) and K&F
Industries and any of its Domestic Subsidiaries may issue Disqualified Stock if the Fixed Charge Coverage Ratio for K&F Industries' most recently ended four full fiscal quarters for which internal
financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock is issued would have been at least 2.0 to 1.0, in each
case determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or Disqualified Stock had been issued, as
the case may be, at the beginning of such four-quarter period. 

        The
first paragraph of this covenant shall not prohibit: 

        (1)   the
incurrence by the Company or any Restricted Subsidiary of additional Indebtedness and letters of credit under one or more Credit Facilities in an aggregate principal
amount at any one time outstanding under this clause (1) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Company and its
Restricted Subsidiaries thereunder) not to exceed $530.0 million, less the sum of all principal payments with respect to such Indebtedness pursuant to clause (A) of Section 4.10; 

        (2)   the
incurrence by the Company and its Restricted Subsidiaries of the Existing Indebtedness; 

        (3)   the
incurrence by the Company of Indebtedness represented by the Notes (including any Additional PIK Notes but excluding any Additional Notes); 

        (4)   (A)
Indebtedness incurred to finance the purchase, improvement or construction of property, plant or equipment (including through the purchase of all of the Capital
Stock of a Person) so long as such Indebtedness is secured by a Lien on the property, plant or equipment so purchased, improved or constructed and such Indebtedness does not exceed the value of such
property, plant or equipment so purchased or constructed or the value of such improvements and such Lien shall not extend to or cover other assets of the Company or any of its Restricted Subsidiaries
other than the property, plant or equipment so purchased, improved or constructed and the real property, if any, on which the property so constructed, improved or purchased, is situated and the
accessions, attachments, replacements and improvements thereto or (B) Indebtedness incurred in connection with any lease financing transaction in conjunction with the acquisition of new
property or improvements to existing property; provided that such lease financing transaction is consummated within 90 days of such acquisition
or completion of such improvements and the aggregate of the Indebtedness incurred pursuant to clauses (A) and (B) does not exceed $15.0 million during any fiscal year (such amount
is referred to as the "Maximum Amount"); provided that the Maximum Amount for each year shall be
increased by the excess, if any, of (a) $30.0 million over (b) the amount of expenditures made in reliance on the provisions of this clause (4) for the immediately
preceding two years; 

        (5)   the
incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness (other than intercompany Indebtedness) in exchange for, or the
net proceeds of which are used to redeem, repurchase, retire, defease, or otherwise refund, refinance, or replace Indebtedness 

50

 

that
was permitted by this Indenture to be incurred under the first paragraph of this covenant or clauses (2), (3), (4), (5) or (6) of this paragraph; 

        (6)   the
incurrence by the Company of Senior Preferred Redemption Debt; 

        (7)   the
incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries;  provided, however, that: 

        (a)   if
the Company is the obligor on such Indebtedness, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations with respect
to the Notes; and 

        (b)   (i) any
subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted
Subsidiary of the Company, (ii) any sale or other transfer of any such Indebtedness to a Person that is neither the Company nor a Restricted Subsidiary of the Company or (iii) the
designation of a Restricted Subsidiary that holds such Indebtedness as an Unrestricted Subsidiary, will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such
Restricted Subsidiary, as the case may be, that was not permitted by this clause (7); 

        (8)   the
incurrence by the Company or any of its Restricted Subsidiaries of Hedging Obligations; 

        (9)   the
guarantee by the Company or any of its Restricted Subsidiaries of Indebtedness of the Company or any of its Restricted Subsidiaries that was permitted to be incurred
by another provision of this Section 4.09; 

        (10) obligations
incurred in the ordinary course of business under (a) bankers acceptances or trade letters of credit which are to be repaid in full not more than one
year after the date on which such Indebtedness is originally incurred to finance the purchase of goods by the Company or a Restricted Subsidiary of the Company; (b) standby letters of credit
issued for the purpose of supporting (i) workers' compensation liabilities of the Company or any of its Restricted Subsidiaries as required by law, (ii) obligations with respect to
leases of the Company or any of its Restricted Subsidiaries, or (iii) performance, payment, deposit or surety obligations of the Company or any of its Restricted Subsidiaries;
(c) performance bonds and surety bonds, and refinancings thereof; and (d) guarantees of Indebtedness incurred in the ordinary course of business of suppliers, licensees, franchisees, or
customers in an aggregate amount not to exceed $5.0 million at any time outstanding; 

        (11) Indebtedness
arising from the honoring by a bank or other financial institution of a check, draft or similar instrument drawn against insufficient funds in the ordinary
course of business, provided, however, that such Indebtedness is extinguished within five business days
of the Company or its applicable Restricted Subsidiary being advised of such incurrence; 

        (12) Indebtedness
under guarantees in respect of obligations of joint ventures of the Company or any of its Restricted Subsidiaries in aggregate principal amount not to
exceed $20.0 million at any one time; 

        (13) Indebtedness
incurred in connection with any sale and leaseback transaction; provided that the aggregate of the
Indebtedness incurred pursuant to this clause (13) shall not exceed $30.0 million at any time outstanding; 

        (14) Indebtedness
to repurchase shares, or cancel options to purchase shares, of Equity Interests of the Company or any Restricted Subsidiary of the Company or any direct or
indirect parent of the Company held by any then current or former director, officer or employee of, or consultant to, the Company or any of its Restricted Subsidiaries;  provided that the aggregate of
the Indebtedness incurred pursuant to this clause (14) shall not exceed $5.0 million in any fiscal year;  provided that the amount 

51

 

available
in any given fiscal year shall be increased by the excess, if any, of (i) $5.0 million over (ii) the amount used pursuant to this clause (14) in the immediately
preceding two fiscal years; 

        (15) Indebtedness
arising from any agreement providing for indemnities, guarantees, purchase price adjustments, holdbacks, contingency payment obligations based on the
performance of the acquired or disposed assets or similar obligations (other than guarantees of Indebtedness) incurred by any Person in connection with the acquisition or disposition of assets; 

        (16) the
incurrence by the Company or any of its Restricted Subsidiaries of Acquired Debt related to the acquisition of a Permitted Business if the Fixed Charge Coverage
Ratio for the Company's most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date of such incurrence of Acquired Debt (the
"Relevant Fixed Charge Coverage Ratio") determined immediately after giving effect to such incurrence and the related acquisition (including through a
merger, consolidation or otherwise) is higher than the Relevant Fixed Charge Coverage Ratio determined immediately before giving effect to such incurrence and the related acquisition; 

        (17) the
issuance of any preferred stock by a Restricted Subsidiary of the Company to the Company or to any other wholly-owned Restricted Subsidiary of the Company; and 

        (18) the
incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness or the issuance of Disqualified Stock or preferred stock of Restricted
Subsidiaries in an aggregate principal amount (or accreted value, as applicable) at any time outstanding not to exceed $25.0 million. 

        The
Company will not incur any Indebtedness under the preceding paragraph if the proceeds thereof are used, directly or indirectly, to refinance any Obligations of the Company
subordinated to the Notes unless such Indebtedness will be subordinated to the Notes to at least the same extent as such subordinated Obligations. 

        If
any Non-Recourse Debt of an Unrestricted Subsidiary shall at any time cease to constitute Non-Recourse Debt or such Unrestricted Subsidiary shall be
redesignated a Restricted Subsidiary, such event will be deemed to constitute an incurrence of Indebtedness by a Restricted Subsidiary. 

        For
purposes of determining compliance with this Section 4.09: 

        (1)   in
the event that an item of proposed Indebtedness meets the criteria of more than one of the categories described in clauses (1) through (18) above, or is
entitled to be incurred pursuant to the first paragraph of this Section 4.09, the Company will be permitted to classify (or later classify or reclassify in whole or in part in its sole
discretion) such item of Indebtedness in any manner that complies with this Section 4.09; 

        (2)   the
accrual of interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness
with the same, or less onerous, terms, the payment of dividends on Disqualified Stock in the form of additional shares of the same class of Disqualified Stock, the accrual of dividends on Disqualified
Stock and the accretion of the liquidation preference of Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of this covenant;  provided, in each such case (except for Specified PIK Interest), that the amount thereof is included in the Fixed Charges of the Company; and
 

        (3)   for
the purposes of determining compliance with any dollar-denominated restriction on the incurrence of Indebtedness denominated in a foreign currency, the
dollar-equivalent principal amount of such Indebtedness incurred pursuant thereto shall be calculated based on the relevant currency exchange rate in effect on the earlier of the date that such
Indebtedness was incurred or the date that the Company or its applicable Restricted Subsidiary committed to incur such Indebtedness. 

52

 

SECTION 4.10.    Asset Sales  

        The Company shall not, and shall not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: 

        (1)   the
Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the fair market value of the assets
or Equity Interests issued or sold or otherwise disposed of (such fair market value to be determined on the date of contractually agreeing to such Asset Sale); 

        (2)   the
fair market value is determined (a) by an executive officer of the Company if the value is less than $10.0 million or (b) in all other cases, by
a resolution of the Company's Board of Directors, in either such case, as set forth in an Officers' Certificate delivered to the Trustee; and 

        (3)   at
least 75% of the consideration received in the Asset Sale by the Company or such Restricted Subsidiary is in the form of cash or Cash Equivalents. For purposes of
this clause (3), each of the following shall be deemed to be cash: 

        (a)   the
amount of any liabilities, as shown on the Company's or such Restricted Subsidiary's most recent balance sheet or in the notes thereto, of the Company or such
Restricted Subsidiary (other than liabilities of the Company that are by their terms subordinated to the Notes and contingent liabilities of the Company or any of its Restricted Subsidiaries) that are
assumed by the transferee of any such assets; and 

        (b)   any
securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are substantially concurrently, subject to
normal settlement periods, converted by the Company or such Restricted Subsidiary into cash or Cash Equivalents (to the extent of the cash or Cash Equivalents received in that conversion); and 

        (c)   property
received as consideration for such Asset Sale that would otherwise constitute a permitted application of Net Proceeds (or other cash in such amount) under
clauses (B) or (D) under the next succeeding paragraph below. 

        Within
390 days (or, if the Senior Preferred Stock is outstanding, 325 days) after the receipt of any Net Proceeds from an Asset Sale, the Company or any of its Restricted
Subsidiaries may apply an amount of cash equal to the amount of those Net Proceeds at its option to: 

        (A)  reduce
or repurchase Indebtedness of (i) the Company that is pari passu in right of payment with the Notes
(provided that if the Company shall so reduce Obligations pari passu in right of payment with the Notes, the Company will offer to equally and ratably
reduce Obligations under the Notes by making an offer (in accordance with the procedures set forth below for an Asset Sale Offer) to all Holders to purchase at a purchase price equal to 100% of the
principal amount thereof, plus accrued and unpaid interest and Additional Interest, if any, the pro rata principal amount of the Notes) or (ii) any Restricted Subsidiary of the Company; and, if
the Indebtedness repaid is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto; 

        (B)  acquire
(including by way of merger or consolidation) all or substantially all of the assets of, or a majority of the Voting Stock of, another Permitted Business; 

        (C)  make
a capital expenditure relating to an asset used or useful in a Permitted Business; or 

        (D)  acquire
other long-term assets that are used or useful in a Permitted Business. 

        Pending
the final application of any Net Proceeds, the Company or any of its Restricted Subsidiaries may temporarily reduce revolving credit borrowings or otherwise invest the Net
Proceeds in any manner that is not prohibited by this Indenture. 

53

 

        To
the extent that the Company and its Restricted Subsidiaries do not apply an amount of cash equal to the amount of such Net Proceeds from Asset Sales during such period as provided in
the second preceding paragraph the amount not so applied shall constitute "Excess Proceeds." No later than the 395th day (or, if the
Senior Preferred Stock is outstanding, the 330th day) after the Asset Sale (or, at the Company's option, an earlier date), if the aggregate amount of Excess Proceeds exceeds
$10.0 million, the Company shall make an offer (an "Asset Sale Offer") to all Holders of Notes and all holders of other Indebtedness that is  pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the
proceeds of sales of assets to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the
Excess Proceeds (the "Offer Amount"). The offer price in any Asset Sale Offer will be equal to 100% of the principal amount (or accreted value, as
applicable) of the Notes and such other pari passu Indebtedness, plus accrued and unpaid interest and Additional Interest (or its equivalent with
respect to any such pari passu Indebtedness), if any, to the date of purchase, and will be payable in cash, in each case, in a minimum of $1,000
aggregate principal amount and integral multiples of $1.00 in excess thereof. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use those Excess Proceeds for any
purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered in such Asset
Sale Offer exceeds the amount of Excess Proceeds, the Excess Proceeds will be allocated by the Company to the Notes and such other pari passu
Indebtedness on a pro rata basis (based upon the respective principal amounts (or accreted value, if applicable) of the Notes and such other pari passu
Indebtedness tendered into such Asset Sale Offer) and the portion of each Note to be purchased will thereafter be determined by the Trustee on a pro rata basis among the Holders of such Notes with
appropriate adjustments such that the Notes may only be purchased in a minimum of $1,000 aggregate principal amount and integral multiples of $1.00 in excess thereof. Upon completion of each Asset
Sale Offer, the amount of Excess Proceeds will be reset at zero. 

        Upon
the commencement of an Asset Sale Offer, the Company shall send, by first class mail, a notice to the Trustee and each of the Holders, with a copy to the Trustee. The notice shall
contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The Asset Sale Offer shall be made to all Holders. The notice, which shall
govern the terms of the Asset Sale Offer, shall state: 

        (1)   that
the Asset Sale Offer is being made pursuant to this Section 4.10 and that such Asset Sale Offer shall remain open for 20 Business Days; 

        (2)   the
Offer Amount attributable to the Notes, the purchase price and the purchase date of the Notes tendered pursuant to the Asset Sale Offer (the
"Purchase Date"); 

        (3)   that
any Note not tendered or accepted for payment shall continue to accrue interest and Additional Interest, if any; 

        (4)   that,
unless the Company defaults in making such payment, any Note accepted for payment pursuant to the Asset Sale Offer shall cease to accrue interest, and Additional
Interest, if any; 

        (5)   that
Holders electing to have a Note purchased pursuant to any Asset Sale Offer shall be required to surrender the Note, with the form entitled "Option of Holder to
Elect Purchase" on the reverse of the Note completed, or transfer by book-entry transfer, to the Company, a Depositary, if appointed by the Company, or a Paying Agent at the address
specified in the notice at least three Business Days before the Purchase Date; 

        (6)   that
Holders shall be entitled to withdraw their election if the Company, the Depositary or the Paying Agent, as the case may be, receives, not later than the expiration
of the offer period, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal 

54

 

amount
of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased; 

        (7)   that,
if the aggregate accreted value of Notes and aggregate principal amount of such other pari passu Indebtedness
tendered by Holders exceeds the Offer Amount, the Company shall select the Notes and such other pari passu Indebtedness to be purchased on a pro rata
basis on the basis of the aggregate accreted value of Notes and the aggregate principal amount of such other pari passu Indebtedness tendered (with such
adjustments as may be deemed appropriate by the Company so that only Notes in denominations of a minimum of $1,000 aggregate principal amount and integral multiples of $1.00 in excess thereof shall be
purchased); and 

        (8)   that
Holders whose Notes were purchased only in part shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or
transferred by book-entry transfer). 

        On
or before the Purchase Date, the Company shall, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes and such other  pari passu Indebtedness or
portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes,
and such other pari passuIndebtedness or portions thereof tendered, and shall deliver to the Trustee an Officers' Certificate stating that such Notes,
and such other pari passu
Indebtedness or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 4.10. The Company, the Depositary or the Paying Agent, as the case may be,
shall on the Purchase Date mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company
shall promptly issue a new Note, and the Trustee, upon written request from the Company shall authenticate and mail or deliver such new Note to such Holder, in a principal amount equal to any
unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company shall publicly announce the results of the
Asset Sale Offer promptly after Purchase Date. 

        If
the Purchase Date is on or after an interest payment record date and on or before the related interest payment date, any accrued and unpaid interest and Additional Interest, if any,
will be paid to the Holder in whose name a Note is registered at the close of business on such record date, and no interest or Additional Interest, if any, will be payable to Holders who tender Notes
pursuant to the Asset Sale Offer. 

        The
Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws
and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the
Asset Sale provisions of this Indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Asset Sale
provisions of this Indenture by virtue of such conflict. 

SECTION 4.11.    Transactions with Affiliates  

        The Company shall not, and shall not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of
its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the
benefit of, any Affiliate of the Company or 

55

 

any
of its Restricted Subsidiaries (each, an "Affiliate Transaction") involving aggregate consideration in excess of $1.0 million, unless: 

        (1)   the
Affiliate Transaction is on terms that are at least as favorable to the Company or the relevant Restricted Subsidiary as those that would have been obtained in a
comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person, provided that any such Affiliated Transaction shall be
conclusively deemed to be at least as favorable as the terms which could be obtained on an arm's length basis with an unrelated Person if such transaction is approved by a majority of the Company's
directors (including a majority of the disinterested members of the Board of Directors); and 

        (2)   the
Company delivers to the Trustee: 

        (a)   with
respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $2.0 million, a resolution of
the Board of Directors set forth in an Officers' Certificate certifying that such Affiliate Transaction complies with this covenant and that such Affiliate Transaction has been approved by a majority
of the disinterested members of the Board of Directors; and 

        (b)   with
respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $10.0 million, or if the
Company does not have any disinterested members, an opinion as to the fairness to the holders of the Notes of such Affiliate Transaction from a financial point of view issued by an accounting,
appraisal or investment banking firm of national standing selected by the Company. 

        The
following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of the prior paragraph: 

        (1)   transactions
between the Company or any of its Restricted Subsidiaries and any employee, officer or director of, or consultant to, the Company, any direct or indirect
parent company of the Company, or any of its Restricted Subsidiaries that are approved by the disinterested members of the Board of Directors; 

        (2)   reasonable
and customary directors' fees, indemnification and similar arrangements for officers, directors or employees, consulting fees, officer or employee salaries,
bonuses or employment agreements, compensation or employee benefit arrangements and incentive arrangements with any officer, director or employee of the Company, any direct or indirect parent company
of the Company or any of its Restricted Subsidiaries and payments under any indemnification arrangements permitted by applicable law; 

        (3)   transactions
between or among the Company and/or its Restricted Subsidiaries; 

        (4)   transactions
with a Person that is an Affiliate of the Company or any Restricted Subsidiary solely because the Company or any Restricted Subsidiary owns an Equity
Interest in, or controls, such Person; 

        (5)   the
pledge of Equity Interests of Unrestricted Subsidiaries to support the Indebtedness thereof; 

        (6)   issuances
and sales of Equity Interests (other than Disqualified Stock) to Affiliates of the Company; 

        (7)   Restricted
Payments that are permitted by Section 4.07; 

        (8)   the
payment of management fees and related expenses to Aurora Management Partners LLC and its Affiliates; provided that
such fees shall not, in the aggregate, exceed $2.0 million (plus out of pocket expenses) in any twelve-month period commencing after the date of this Indenture; 

56

 

        (9)   the
payment of transaction, consulting and advisory fees and related expenses to Aurora Management Partners LLC and its Affiliates for financial advisory, financing,
underwriting or placement services or in respect of other investment banking activities, including without limitation, in connection with acquisitions or divestitures, in each case, which payments are
(a) reasonably related to the services performed and (b) either (i) under $10.0 million in any fiscal year or (ii) approved by a majority of the members of the Board
of Directors of the Company; and 

        (10) the
payment of all fees and expenses related to the Acquisition Transactions, which are described in the Offering Memorandum. 

SECTION 4.12.    Liens  

        The Company shall not create, incur, assume or otherwise cause or suffer to exist any Lien of any kind securing Indebtedness, Attributable Debt or trade payables
(other than Permitted Liens) upon any of its property or assets, now owned or hereafter acquired, unless all payments due under this Indenture and the Notes are secured (i) in the case of Liens
securing Indebtedness that is pari passu in right of payment to the Notes, on an equal and ratable basis with the obligations so secured until such time
as such obligations are no longer secured by a Lien and (ii) in the case of Liens securing Indebtedness that
is expressly subordinate or junior in right of payment to the Notes, on a senior basis to the obligations so secured with the same relative priority as the Notes shall have to that subordinated or
junior Indebtedness until such time as such obligations are no longer secured by a Lien. 

SECTION 4.13.    Business Activities  

        The Company shall not, and shall not permit any Restricted Subsidiary to, engage in any business other than Permitted Businesses, except to such extent as would
not be material to the Company and its Subsidiaries taken as a whole. 

SECTION 4.14.    Corporate Existence  

        Subject to Article 5 hereof, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect (i) its
corporate existence, and the corporate, partnership or other existence of each of its Restricted Subsidiaries, in accordance with the respective organizational documents (as the same may be amended
from time to time) of the Company or any such Restricted Subsidiary and (ii) the rights (charter and statutory), licenses and franchises of the Company and its Subsidiaries, except where the
failure to do so would not have a material adverse effect on the ability of the Company to perform its obligations under the Notes or this Indenture. 

SECTION 4.15.    Offer to Repurchase upon Change of Control  

        If a Change of Control occurs, the Company will be required to make an offer (a "Change of Control Offer") to each
Holder of Notes, unless the Company has exercised its right to redeem all the Notes as described under Section 3.07, to repurchase all or any part (equal to $1,000 or an integral multiple of
$1,000) of that Holder's Notes on the terms set forth in this Indenture. In the Change of Control Offer, the Company will offer a payment in cash (the "Change of Control
Payment") equal to 101% of the aggregate principal amount of the Notes repurchased plus accrued and unpaid interest and Additional Interest, if any, on the Notes repurchased,
to the date of purchase (the "Change of Control Payment Date"). Within 30 days following any Change of Control, the Company shall mail a notice
to each Holder stating: (i) that the Change of Control Offer is being made pursuant to this Section 4.15 (and describing the transaction or transactions that constitute the Change of
Control) and that all Notes tendered shall be accepted for payment; (ii) the purchase price and Change of Control Payment Date, which shall be no earlier than 30 days and no later than
60 days from the date such 

57

 

notice
is mailed; (iii) that any Note not tendered shall continue to accrue interest and Additional Interest, if any; (iv) that, unless the Company defaults in the payment of the Change
of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer shall cease to accrue interest and Additional Interest, if any, after the Change of Control Payment Date;
(v) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer shall be required to surrender the Notes, with the form entitled "Option of Holder to Elect Purchase"
on the reverse of the Notes completed, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date;
(vi) that Holders shall be entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the second Business Day preceding the Change of Control
Payment Date, a facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing his
election to have the Notes purchased; and (vii) that Holders whose Notes are being purchased only in part shall be issued new Notes equal in principal amount to the unpurchased portion of the
Notes surrendered, which unpurchased portion must be in a minimum principal amount of $2,000 or an integral multiple of $1.00 in excess thereof. 

        The
Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws
and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with
the Change of Control provisions of this Indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this
Section 4.15 by virtue of such conflict. 

        On
the Change of Control Payment Date, the Company shall, to the extent lawful: 

        (1)   accept
for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer; 

        (2)   deposit
with the paying agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and 

        (3)   deliver
or cause to be delivered to the Trustee the Notes properly accepted together with an Officers' Certificate stating the aggregate principal amount of the Notes or
portions of Notes being purchased by the Company. 

        The
Paying Agent shall promptly mail to each Holder of Notes validly tendered the Change of Control Payment for such Notes, and the Trustee shall promptly authenticate and mail (or cause
to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any;  provided that each new Note will be in a minimum
principal amount of $2,000 or an integral multiple of $1.00 in excess thereof. The Company shall
publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. 

        If
the Change of Control Payment Date is on or after an interest payment record date and on or before the related interest payment date, any accrued and unpaid interest and Additional
Interest, if any, shall be paid (or Additional PIK Notes shall be issued, in the case the Company elects to pay interest in the form of Additional PIK Notes pursuant to Section 2.15 hereof) to
the Holder in whose name a Note is registered at the close of business on such record date, and no other interest or Additional Interest, if any, will be payable to Holders who tender pursuant to the
Change of Control Offer. 

        The
Company shall not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise
in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer 

58

 

made
by the Company and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer or if an irrevocable notice of redemption has been given pursuant to
Section 3.03. 

SECTION 4.16.    Future Subsidiary Guarantees  

        The Company will cause each Restricted Subsidiary that guarantees any Indebtedness of the Company to execute and deliver to the Trustee a supplemental indenture
in form and substance set forth in Exhibit E pursuant to which such Restricted Subsidiary will guarantee payment of the Notes; provided that, if
such Indebtedness is by its terms subordinated in right of payment to the Notes, any such guarantee of such Restricted Subsidiary with respect to such Indebtedness shall be subordinated to such
Guarantor's Subsidiary Guarantee substantially to the same extent as such Indebtedness is subordinated to the Notes. 

        Each
Subsidiary Guarantee will be limited to an amount not to exceed the maximum amount that can be guaranteed by that Restricted Subsidiary without rendering the Subsidiary Guarantee,
as it relates to such Restricted Subsidiary, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally. 

SECTION 4.17.    Designation of Unrestricted Subsidiaries  

        The Board of Directors may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted
Subsidiary is designated as an Unrestricted Subsidiary, the aggregate fair market value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary properly
designated will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under the first paragraph of Section 4.07 or
Permitted Investments, as determined by the Company. That designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the
definition of an Unrestricted Subsidiary. The Board of Directors may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if the redesignation would not cause a Default. 

        All
Subsidiaries of Unrestricted Subsidiaries shall be automatically deemed to be Unrestricted Subsidiaries. All designations of Subsidiaries as Unrestricted Subsidiaries and revocations
thereof must be evidenced by filing with the Trustee resolutions of the Board of Directors of the Company and an Officers' Certificate certifying compliance with the foregoing provisions. 

SECTION 4.18.    Payments for Consent  

        The Company shall not, and shall not permit any of its Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of
any Holder of Notes for or as an
inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid and is paid to all Holders of the Notes
that consent, waive or agree to amend in the applicable time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

  SUCCESSORS

SECTION 5.01.    Merger, Consolidation or Sale of Assets  

        The Company may not, directly or indirectly: (1) consolidate or merge with or into another Person (whether or not the Company is the surviving
corporation); or (2) sell, assign, transfer, convey, lease or 

59

 

otherwise
dispose of all or substantially all of the properties or assets of the Company and its Restricted Subsidiaries taken as a whole, in one or more related transactions, to another Person,
unless: 

        (1)   either:
(a) the Company is the surviving corporation; or (b) the Person formed by or surviving any such consolidation or merger (if other than the Company)
or to which such sale, assignment, transfer, conveyance, lease or other disposition has been made is a corporation organized or existing under the laws of the United States, any state of the United
States or the District of Columbia; 

        (2)   the
Person formed by or surviving any such consolidation or merger (if other than the Company) or the Person to which such sale, assignment, transfer, conveyance, lease
or other disposition has been made assumes all the obligations of the Company under the Notes, this Indenture and the Registration Rights Agreement pursuant to agreements reasonably satisfactory to
the Trustee; 

        (3)   immediately
after such transaction no Default or Event of Default exists; and 

        (4)   the
Company or the Person formed by or surviving any such consolidation or merger (if other than the Company), or to which such sale, assignment, transfer, conveyance,
lease or other disposition has been made will, on the date of such transaction after giving pro forma effect thereto and any related financing transactions as if the same had occurred at the beginning
of the applicable four-quarter period, be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in clause (i) of
the first paragraph of Section 4.09. 

        For
purposes of this Section, the sale, assignment, transfer, conveyance, lease or other disposition of all or substantially all of the properties and assets of one or more Restricted
Subsidiaries of the Company, which properties and assets, if held by the Company instead of such Restricted Subsidiaries, would constitute all or substantially all of the properties and assets of the
Company on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company. 

        Notwithstanding
the preceding clause (4), (x) any Restricted Subsidiary may consolidate with, merge into, sell, assign, convey, lease or otherwise transfer all or part of
its properties and assets to the Company or to any other Restricted Subsidiary and (y) the Company may merge with an Affiliate incorporated solely for the purpose of reincorporating the Company
in another jurisdiction to realize tax benefits. 

SECTION 5.02.    Successor Corporation Substituted  

        Upon any consolidation or merger, or any sale, assignment, transfer, conveyance or other disposition of all or substantially all of the assets of the Company in
accordance with Section 5.01 hereof, the successor corporation formed by such consolidation or into or with which the Company is merged or to which such sale, assignment, transfer, conveyance
or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, conveyance or other disposition, the provisions of this
Indenture referring to the Company shall refer instead to the successor corporation and not to the Company), and may exercise every right and power of the Company under this Indenture with the same
effect as if such successor Person had been named as the Company herein. The predecessor company shall be relieved from the obligation to pay the principal of and interest on the Notes (and its
obligations to the Trustee pursuant to Section 7.07) only in the case of a sale or other disposition of all or substantially all of the properties and assets of all of the Company and its
Restricted Subsidiaries taken as a whole that meets the requirements of Section 5.01 hereof. The successor Person shall execute a supplemental indenture in form and substance satisfactory to
the Trustee and deliver an Opinion of Counsel satisfactory to the Trustee to the Trustee within ten Business Days of the date of any such consolidation or merger, or any sale, assignment, transfer,
conveyance or other disposition of all or substantially all of the assets of the Company.

created after the date of this Indenture, if that default: 

        (a)   is

Indebtedness on the date of such default (a "Payment Default"); or 

        (b)   results

SECTION 6.02.    Acceleration  

        In the case of an Event of Default arising from clause (9) or (10) of the first paragraph of Section 6.01, with respect to the Company or any
Restricted Subsidiary that is a Significant Subsidiary or any group of Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, all outstanding Notes will become due and payable
immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes, by
notice in writing to the Trustee and the Company designated as a "Notice of Default," may declare all the Notes to be due and payable and, upon any such declaration, such principal amount (and
premium, if any) and accrued interest, notwithstanding anything contained in this Indenture or the Notes to the contrary, will become immediately due and payable. Any such declaration with respect to
the Notes may be annulled by the Holders of a majority in aggregate principal amount of the then outstanding Notes upon the conditions set forth herein. 

        Notwithstanding
the foregoing, if an Event of Default specified in clause (6) of Section 6.01 shall have occurred and be continuing, such Event of Default and any
consequential acceleration shall be automatically rescinded if (i) the Indebtedness that is the subject of such Event of Default has been repaid, or (ii) if the default relating to such
Indebtedness is waived or cured and if such Indebtedness has been accelerated, then the Holders thereof have rescinded their declaration of acceleration in respect of such Indebtedness. 

        Any
such declaration with respect to the Notes may be rescinded and annulled by the Holders of a majority in aggregate principal amount of the outstanding Notes by written notice to the
Trustee, except a continuing Default or Event of Default in the payment of principal of, or interest or premium or Additional Interest, if any, on the Notes, if (i) the rescission would not
conflict with any judgment or decree of a court of competent jurisdiction, (ii) all existing Events of Default have been cured or waived except nonpayment of principal of or interest on the
Notes that has become due solely by such declaration of acceleration, (iii) to the extent the payment of such interest is lawful, interest (at the same rate specified in the Notes) on overdue
installments of interest and overdue payments of principal, which has become due otherwise than by such declaration of acceleration, has been paid, (iv) the Company has paid the Trustee its
reasonable compensation and reimbursed the Trustee for its expenses, disbursements and advances and (v) in the event of the cure or waiver of a Default or Event of Default of the type described
in Section 6.01(9) and (10) the Trustee has received an Officers' Certificate and Opinion of Counsel that such Default or Event of Default has been cured or waived. No such rescission
shall affect any subsequent Default or impair any right consequent thereto. 

62

 

SECTION 6.03.    Other Remedies  

        If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium on, Additional Interest,
if any, and interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture. 

        The
Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of
a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law. 

SECTION 6.04.    Waiver of Past Defaults  

        Subject to Section 9.02 and in any event in accordance with the conditions set forth in the last paragraph of Section 6.02, Holders of not less than
a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive an existing Default or Event of Default and its
consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium and Additional Interest on, or interest on the Notes (including in connection with
an offer to purchase); provided that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration
and its consequences, including any related payment default that resulted from such acceleration, so long as
such acceleration was not the result of a payment default. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for
every purpose of this Indenture, but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. 

SECTION 6.05.    Control by Majority  

        Holders of a majority in principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any
remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee
determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability. 

SECTION 6.06.    Limitation on Suits  

        A Holder of a Note may pursue a remedy with respect to this Indenture or the Notes only if: 

        (a)   the
Holder of a Note gives to the Trustee written notice of a continuing Event of Default; 

        (b)   the
Holders of at least 25% in principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy; 

        (c)   such
Holder of a Note or Holders of Notes offer and, if requested, provide to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense; 

        (d)   the
Trustee does not comply with the request within 60 days after receipt of the request and the offer and, if requested, the provision of indemnity; and 

        (e)   during
such 60-day period the Holders of a majority in principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with
the request. 

        A
Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note. 

63

 

SECTION 6.07.    Rights of Holders of Notes to Receive Payment  

        Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium and Additional Interest, if any,
and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or
after such respective dates, shall not be impaired or affected without the consent of such Holder. 

SECTION 6.08.    Collection Suit by Trustee  

        If an Event of Default specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee is authorized to recover judgment in its own name
and as trustee of an express trust against the Company for the whole amount of principal of, premium and Additional Interest, if any, and interest remaining unpaid on the Notes and interest on overdue
principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel. 

SECTION 6.09.    Trustee May File Proofs of Claim  

        The Trustee is authorized 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
(including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings
relative to the Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable
or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder 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 Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its
agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 7.07 hereof out of the estate in any such proceeding, 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, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or
arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization,
arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 

SECTION 6.10.    Priorities  

        After an Event of Default, any money or other property distributable in respect of the Company's obligations under this Indenture shall be paid in the following
order: 

        First:    to the Trustee (including any predecessor Trustee), its agents and attorneys for amounts due under Section 7.07
hereof, including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 

        Second:    to Holders of Notes for amounts due and unpaid on the Notes for principal, premium and Additional Interest, if any,
and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium and Additional Interest, if any and interest,
respectively; and 

64

 

        Third:    to the Company or to such party as a court of competent jurisdiction shall direct in writing. 

        The
Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10. 

SECTION 6.11.    Undertaking for Costs  

        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 a Trustee,
a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs,
including reasonable attorneys' fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This
Section does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding
Notes.

        (l)    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. 

        (m)  The
Trustee shall not be responsible or liable for any failure or delay in the performance of its obligations under this Indenture arising out of or caused, directly or
indirectly, by circumstances beyond its reasonable control, including, without limitation, acts of God; earthquakes; fire; flood; terrorism; wars and other military disturbances; sabotage; epidemics;
riots; interruptions; loss or malfunctions of utilities, computer (hardware or software) or communication services; accidents; labor disputes; acts of civil or military authority and governmental
action. 

SECTION 7.03.    Individual Rights of Trustee  

        The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of the
Company with the same rights it would have if it were not Trustee. If the Trustee does become a creditor of the Company, this indenture limits its rights to obtain payment of claims in certain cases,
or to realize on certain property received in respect of any such claim as security or otherwise. However, in the event that the Trustee acquires any conflicting interest it must eliminate such
conflict within 90 days, apply to the Commission for
permission to continue as trustee or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof. 

SECTION 7.04.    Trustee's Disclaimer  

        The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes or any security for the payment
of the Notes, it shall not be accountable for the Company's use of the proceeds from the Notes or any money paid to the Company or upon the Company's direction under any provision of this Indenture,
it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any
statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication. 

SECTION 7.05.    Notice of Defaults  

        If a Default or Event of Default occurs and is continuing and if it is actually known to a Responsible Officer of the Trustee, the Trustee shall mail to Holders
of Notes a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium and Additional
Interest, if any, or interest on any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the
interests of the Holders of the Notes. 

67

 

SECTION 7.06.    Reports by Trustee to Holders of the Notes  

        Within 60 days after each May 15 beginning with the May 15 following the Issue Date, and for so long as Notes remain outstanding, the Trustee
shall mail to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA § 313(a) (but if no event described in TIA § 313(a) has occurred
within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with TIA § 313(b)(2) to the extent applicable. The Trustee shall also
transmit by mail all reports as required by TIA § 313(c). 

        A
copy of each report at the time of its mailing to the Holders of Notes shall be mailed to the Company and filed with the Commission and each stock exchange on which the Notes are
listed in accordance with TIA § 313(d). The Company shall promptly notify the Trustee when the Notes are listed on any stock exchange or any delisting thereof. 

SECTION 7.07.    Compensation and Indemnity  

        The Company shall pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and services hereunder. The Trustee's
compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee promptly upon written request for all reasonable disbursements,
advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee's
agents and counsel. 

        The
Company shall indemnify the Trustee against any and all losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its
duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Company (including this Section 7.07) and defending itself against any claim (whether
asserted by the Company or any Holder or any other person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss,
liability or expense may be attributable to its negligence or bad faith or willful misconduct. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by
the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have
separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent. 

        The
obligations of the Company under this Section 7.07 shall survive the resignation or removal of the Trustee, the satisfaction and discharge of this Indenture and the
termination of this Indenture. 

        To
secure the Company's payment obligations in this Section, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held
in trust to pay principal and interest on particular Notes. Such Lien shall survive the resignation or removal of the Trustee, the satisfaction and discharge of this Indenture and the termination of
this Indenture. 

        In
addition and without prejudice to its rights hereunder, when the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(9) or
(10) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under
any Bankruptcy Law. 

SECTION 7.08.    Replacement of Trustee  

        A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee's acceptance of appointment
as provided in this Section. 

68

 

        The
Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Company. The Holders of Notes of a majority in principal amount of the
then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing. The Company may remove the Trustee if: 

        (a)   the
Trustee fails to comply with Section 7.10 hereof; 

        (b)   the
Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law; 

        (c)   a
Custodian or public officer takes charge of the Trustee or its property; or 

        (d)   the
Trustee becomes incapable of acting. 

        If
the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. Within one year after the
successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company. 

        If
a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of Notes of at least
10% in principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee. 

        If
the Trustee, after written request by any Holder of a Note who has been a Holder of a Note for at least six months, fails to comply with Section 7.10, such Holder of a Note may
petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

        A
successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee shall
become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders of
the Notes. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee; provided all sums owing to the
Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company's
obligations under Section 7.07 hereof shall continue for the benefit of the retiring Trustee. 

SECTION 7.09.    Successor Trustee by Merger, etc.  

        If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another Person, the successor
Person without any further act shall be the successor Trustee. 

SECTION 7.10.    Eligibility; Disqualification  

        There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state
thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and
surplus of at least $50 million as set forth in its most recent published annual report of condition. 

        This
Indenture shall always have a Trustee who satisfies the requirements of TIA § 310(a)(1), (2) and (5). The Trustee is subject to TIA § 310(b). Nothing
herein shall prohibit the Trustee from making the application to the Commission referred to in the penultimate paragraph of Section 310(b) of the TIA. 

69

 

        For
purposes of Section 310(b)(1) of the TIA and to the extent permitted thereby, the Trustee shall not be deemed to have a conflicting interest arising from its capacity as
trustee in respect of the indenture governing the Existing Notes. 

SECTION 7.11.    Preferential Collection of Claims Against the Company  

        The Trustee is subject to TIA § 311(a), excluding any creditor relationship listed in TIA § 311(b). A Trustee who has resigned or been
removed shall be subject to TIA § 311(a) to the extent indicated therein. 

ARTICLE 8
  LEGAL DEFEASANCE AND COVENANT DEFEASANCE

SECTION 8.01.    Option to Effect Legal Defeasance or Covenant Defeasance  

        The Company may, at the option of its Board of Directors evidenced by a resolution set forth in an Officers' Certificate, at any time, elect to have either
Section 8.02 or 8.03 hereof applied to all outstanding Notes upon compliance with the conditions set forth below in this Article Eight. 

SECTION 8.02.    Legal Defeasance and Discharge  

        Upon the Company's exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company and each of the Guarantors, if any,
shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from all of its obligations with respect to all outstanding Notes
(including any Subsidiary Guarantees) and this Indenture on the date the conditions set forth below are satisfied and, if applicable, the Guarantors shall be deemed to have been discharged with
respect to their Subsidiary Guarantees (hereinafter, "Legal Defeasance"). For this purpose, Legal Defeasance means that the Company and the Guarantors,
if any, shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including any Subsidiary Guarantees), which shall thereafter be deemed to be
"outstanding" only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in (a) and (b) below, and to have satisfied all its other
obligations under such Notes, the Subsidiary Guarantees, if any, and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the
same); provided that the following provisions which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders
of outstanding Notes to receive
solely from the trust fund described in Section 8.04 hereof, and as more fully set forth in such Section, payments in respect of the principal of or premium, if any, Additional Interest, if
any, or interest on the Notes when such payments are due, (b) the Company's obligations with respect to the Notes concerning issuing temporary Notes, registration of Notes and mutilated,
destroyed, lost or stolen Notes and the maintenance of an office or agency for payment and money for security payments held in trust, (c) the rights, powers, trusts, duties and immunities of
the Trustee hereunder and the Company's and the Guarantors', if any, obligations in connection therewith and (d) this Article 8. Subject to compliance with this Article 8, the
Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof. 

SECTION 8.03.    Covenant Defeasance  

        Upon the Company's exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company and the Guarantors, if any, shall,
subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from its obligations under the covenants contained in Article 4 (other those in Sections 4.01,
4.02, 4.06 and 4.14) and in clause (3) of Section 5.01(4) hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 are satisfied
(hereinafter, "Covenant Defeasance"), and the Notes shall thereafter 

70

 

be
deemed not "outstanding" for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall
continue to be deemed "outstanding" for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant
Defeasance means that, with respect to the outstanding Notes and any Subsidiary Guarantees, the Company and the Guarantors, if applicable, may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any
reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01
hereof, but, except as specified above, the remainder of this Indenture and such Notes and any Subsidiary Guarantees shall be unaffected thereby. In addition, upon the Company's exercise under
Section 8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(6) through
6.01(8) hereof shall not constitute Events of Default. 

SECTION 8.04.    Conditions to Legal or Covenant Defeasance  

        The following shall be the conditions to the application of either Section 8.02 or 8.03 hereof to the outstanding Notes: 

        (1)   the
Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Notes, cash in U.S. dollars, non-callable Government
Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient, in the opinion of a nationally recognized investment bank or
firm of independent public accountants, to pay the principal of, or interest and premium and Additional Interest, if any, on the outstanding Notes on the Stated Maturity or on the applicable
redemption date specified by the Company, as the case may be, and the Company must specify whether the Notes are being defeased to maturity or to a particular redemption date; 

        (2)   in
the case of an election under Section 8.02 hereof, the Company has delivered to the Trustee an opinion of counsel reasonably acceptable to the Trustee
confirming that: 

        (a)   the
Company has received from, or there has been published by, the Internal Revenue Service a ruling; or 

        (b)   since
the date of this Indenture, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such opinion of
counsel will confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to
federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; 

        (3)   in
the case of an election under Section 8.03 hereof, the Company has delivered to the Trustee an opinion of counsel reasonably acceptable to the Trustee
confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 

        (4)   no
Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds
to be applied to such deposit) or insofar as Events of Default from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91st day after the date of deposit; 

71

 

        (5)   such
Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than
this Indenture) to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound; 

        (6)   the
Company must have delivered to the Trustee an opinion of counsel, subject to customary qualifications, to the effect that after the 91st day following the deposit,
no trust funds will be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors' rights generally or in connection with Covenant Defeasance,
such trust funds will be subject to a first priority lien in favor of the Trustee for the benefit of the Holders of Notes; 

        (7)   the
Company must deliver to the Trustee an Officers' Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders of Notes
over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others; and 

        (8)   the
Company must deliver to the Trustee an Officers' Certificate and an opinion of counsel, each stating that all conditions precedent relating to the Legal Defeasance
or the Covenant Defeasance have been complied with. 

SECTION 8.05.    Deposited Money and Government Securities to Be Held in Trust; Other Miscellaneous Provisions  

        Subject to Section 8.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee
(or other qualifying trustee, collectively for purposes of this Section 8.05, the "Trustee") pursuant to Section 8.04 hereof in respect of the outstanding Notes shall be held in trust
and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying
Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal of or premium, if any, Additional Interest, if any, or interest, but
such money need not be segregated from other funds except to the extent required by law. 

        The
Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited
pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the
outstanding Notes. 

        Anything
in this Article 8 to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the request of the Company any money or
non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in
a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(a) hereof), are in excess of the amount thereof that would then be required to be
deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. 

SECTION 8.06.    Repayment to the Company  

        Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of or premium, if any, Additional
Interest, if any, or interest on the Notes and remaining unclaimed for two years after such principal, and premium, if any, Additional Interest, if any, or interest has become due and payable shall be
paid to the Company on its request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as a secured creditor, look only to the Company
for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as 

72

 

trustee
thereof, shall thereupon cease; provided that the Trustee or such Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, in The New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining shall be repaid to the Company. 

SECTION 8.07.    Reinstatement  

        If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable Government Securities in accordance with
Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then
the Company's and, if any, the Guarantors' obligations under this Indenture and the Notes and, if applicable, the Subsidiary Guarantees shall be revived and reinstated as though no deposit had
occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as
the case may be; provided that, if the Company has made any payment of principal of, premium, if any, Additional Interest, if any, or interest on 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 9
  AMENDMENT, SUPPLEMENT AND WAIVER

SECTION 9.01.    Without Consent of Holders of Notes  

        Notwithstanding Section 9.02 of this Indenture, the Company and the Trustee may amend or supplement this Indenture or the Notes without the consent of any
Holder of a Note to: 

        (1)   cure
any ambiguity, defect or inconsistency; 

        (2)   provide
for uncertificated Notes in addition to or in place of certificated Notes (provided that the uncertificated Notes are issued in registered form for purposes of
Section 163(f) of the Code, or in a manner such that the uncertificated Notes are described in Section 163(f)(2)(B) of the Code); 

        (3)   provide
for the assumption of the Company's obligations to Holders of Notes in the case of a merger or consolidation or sale of all or substantially all of the Company's
assets; 

        (4)   make
any change that would provide any additional rights or benefits to the Holders of Notes or that does not adversely affect the rights under this Indenture of any
such Holder; 

        (5)   provide
for the issuance of Additional Notes in accordance with the provisions set forth in this Indenture; 

        (6)   evidence

        (8)   add
Subsidiary Guarantees with respect to the Notes; or 

        (9)   comply
with requirements of the Commission in order to effect or maintain the qualification of the indenture under the TIA. 

        Upon
the request of the Company accompanied by a resolution of the Board of Directors of the Company authorizing the execution of any such amended or supplemental indenture, and upon
receipt by the Trustee of the documents described in Section 9.06 hereof, the Trustee shall join with the 

73

 

Company
in the execution of any amended or supplemental Indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be
therein contained, but the Trustee shall not be obligated to enter into such amended or supplemental Indenture that affects its own rights, duties or immunities under this Indenture or otherwise. 

SECTION 9.02.    With Consent of Holders of Notes  

        Except as provided in Section 9.01 or below in this Section 9.02, the Company and the Trustee may amend or supplement this Indenture and the Notes
may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the Notes then outstanding voting as a single class (including, without limitation,
consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default or
compliance with any provision of this Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes voting as a single class
(including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes). Section 2.09 hereof shall determine which Notes are
considered to be "outstanding" for purposes of this Section 9.02. 

        However,
without the consent of each Holder affected, an amendment or waiver under this Section 9.02 may not (with respect to any Notes held by a nonconsenting Holder): 

        (1)   reduce
the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver; 

        (2)   reduce
the principal of (or the premium on) or change the fixed maturity of any Note or alter the provisions with respect to the redemption of the Notes (other than
provisions relating to the covenants contained in Section 4.10 and Section 4.15); 

        (3)   reduce
the rate of or change the time for payment of interest or Additional Interest on any Note; 

        (4)   waive
a Default or Event of Default in the payment of principal of, or interest or premium or Additional Interest, if any, on the Notes (except a rescission of
acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the Notes and a waiver of the payment default that resulted from such acceleration); 

        (5)   make
any Note payable in currency other than that stated in the Notes; 

        (6)   make
any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive payments of principal of, or
interest or premium or Additional Interest, if any, on the Notes; 

        (7)   waive
a redemption payment with respect to any Note (other than a payment required by Section 4.10 or Section 4.15); 

        (8)   release
any Guarantor from any of its obligations under its Subsidiary Guarantee or this Indenture, except in accordance with the terms of this Indenture; or 

        (9)   make
any change in the preceding amendment and waiver provisions. 

        In
addition, any amendment to, or waiver of, the provisions of this Indenture relating to subordination that adversely affects the rights of the Holders of the Notes will require the
consent of the Holders of at least 75% in aggregate principal amount of Notes then outstanding. 

        Upon
the request of the Company accompanied by a resolution of the Board of Directors of the Company authorizing the execution of any such amended or supplemental Indenture, and upon the
filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as 

74

 

aforesaid,
and upon receipt by the Trustee of the documents described in Section 9.06 hereof, the Trustee shall join with the Company in the execution of such amended or supplemental Indenture
unless such amended or supplemental Indenture directly affects the Trustee's own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but
shall not be obligated to, enter into such amended or supplemental Indenture. 

SECTION 9.03.    Compliance with Trust Indenture Act  

        Every amendment or supplement to this Indenture or the Notes shall be set forth in an amended or supplemental Indenture that complies with the TIA as then in
effect. 

SECTION 9.04.    Revocation and Effect of Consents  

        Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every
subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder's Note, even if notation of the consent is not made on any Note. However, any such Holder of a
Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An
amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder. 

SECTION 9.05.    Notice of Amendment; Notation on or Exchange of Notes  

        After any amendment under this Article becomes effective, the Company shall mail to Holders of Notes a notice briefly describing such amendment. The failure to
give such notice to all Holders of Notes, or any defect therein, shall not impair or affect the validity of an amendment under this Article. 

        The
Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company in exchange for all Notes may issue and the
Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver. 

        Failure
to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver. 

        SECTION 9.06.    Trustee to Sign Amendments, etc.

        The
Trustee shall sign any amended or supplemental Indenture authorized pursuant to this Article 9 if the amendment or supplement, in the sole discretion of the Trustee, does not
adversely affect the rights, duties, liabilities or immunities of the Trustee. In executing any amended or supplemental indenture, the Trustee shall be entitled to receive and (subject to
Section 7.01 hereof) shall be fully protected in relying upon, in addition to the documents required by Section 12.04 hereof, an Officers' Certificate and an Opinion of Counsel stating
that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture. 

ARTICLE 10
  SUBSIDIARY GUARANTEES

SECTION 10.01.    Guarantee  

        (a)   Subject
to this Article 10, each of the Guarantors, if any, hereby, jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and
delivered by the Trustee and to 

75

 

the
Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Company hereunder or thereunder, that: 

        (i)    the
principal of, premium and Additional Interest, if any, and interest on the Notes will be promptly paid in full when due, whether at maturity, by acceleration,
redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or
thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof, and 

        (ii)   in
case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed in
accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise. 

        Failing
payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay the same
immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. 

        (b)   The
Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the Notes or this
Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any
action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. 

        (c)   Each
Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right
to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenant that this Subsidiary Guarantee will not be discharged except by complete performance of the
obligations contained in the Notes and this Indenture. 

        (d)   If
any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors or any custodian, trustee, liquidator or other similar
official acting in relation to either the Company or the Guarantors, any amount paid by either to the Trustee or such Holder, this Subsidiary Guarantee, to the extent theretofore discharged, will be
reinstated in full force and effect. 

        (e)   Each
Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment
in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the
maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Subsidiary Guarantee, notwithstanding any stay, injunction or other
prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in
Article 6 hereof, such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Subsidiary Guarantee. 

        (f)    The
Guarantors will have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the
Holders under the Subsidiary Guarantee. 

SECTION 10.02.    Limitation on Guarantor Liability  

        Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Subsidiary Guarantee of such
Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state
law to the extent 

76

 

applicable
to any Subsidiary Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be
limited to the maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving
effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this
Article 10, result in the obligations of such Guarantor under its Subsidiary Guarantee not constituting a fraudulent transfer or conveyance. 

SECTION 10.03.    Guarantors May Consolidate, etc., on Certain Terms  

        No Guarantor may sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such Guarantor
is the surviving Person), another Person, other than the Company or another Guarantor, unless: 

        (1)   immediately
after giving effect to such transaction, no Default or Event of Default exists; and 

        (2)   either:

        (a)   the
Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such consolidation or merger unconditionally assumes all the
obligations of that
Guarantor under this Indenture (including its Subsidiary Guarantee) and the Registration Rights Agreement pursuant to agreements reasonably satisfactory to the trustee; or 

        (b)   the
Net Proceeds of such sale or other disposition will be required to be applied in accordance with the applicable provisions of this Indenture. 

SECTION 10.04.    Releases of Subsidiary Guarantees  

        The Subsidiary Guarantee of a Guarantor will be released: 

        (1)   in
connection with any sale, disposition or other transfer (including through merger or consolidation) of (x) the Equity Interests of such Guarantor following
which such Guarantor is no longer a Subsidiary of the Company or (y) all or substantially all the assets of the applicable Guarantor, in each case, to a Person that is not (either before or
after giving effect to such transaction) a Subsidiary of the Company if such sale, disposition or other transfer is made in compliance with the applicable provisions of this Indenture; 

        (2)   upon
the release or discharge of the guarantee by such Guarantor of Indebtedness of the Company which resulted in the obligation to guarantee the Notes; 

        (3)   in
connection with the Legal Defeasance of the Notes and the Subsidiary Guarantees; or 

        (4)   if
the Company designates any Restricted Subsidiary that is a Guarantor as an Unrestricted Subsidiary in accordance with the applicable provisions of this Indenture. 

77

 

ARTICLE 11
  SATISFACTION AND DISCHARGE

SECTION 11.01.    Satisfaction and Discharge  

        This Indenture shall be discharged and will cease to be of further effect as to all Notes and Subsidiary Guarantees issued hereunder, except as to surviving
rights of registration of transfer or exchange of the Notes, when: 

        (a)   either:

        (i)    all
Notes that have been previously authenticated (except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money has
previously been deposited in trust or segregated and held in trust by the Company and is thereafter repaid to the Company or discharged from the trust) have been delivered to the Trustee for
cancellation; or 

        (ii)   all
Notes that have not been previously delivered to the Trustee for cancellation (A) have become due and payable by reason of the mailing of a notice of
redemption or otherwise or (B) will become due and payable at their maturity within one year or (C) are to be called for redemption within one year under arrangements satisfactory to the
Trustee for the giving of a notice of redemption by the Trustee, and the Company or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely
for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient without consideration of any
reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not previously delivered to the Trustee for cancellation for principal, premium, if any, and interest and Additional
Interest, if any, on the Notes to the date of deposit, in the case of Notes that have become due and payable, or to the Stated Maturity or redemption date, as the case may be; 

        (b)   the
Company or any Guarantor has paid or caused to be paid all other sums payable by it under this Indenture; 

        (c)   no
Default or Event of Default has occurred and is continuing on the date of such deposit or shall occur as a result of such deposit and such deposit shall not result in
a breach or violation of, or constitute a default under, any other instrument to which the Company is a party or by which the Company or any Guarantor is bound; and 

        (d)   the
Company has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of the Notes at maturity or the
redemption date, as the case may be. 

        In
addition, the Company must deliver an Officers' Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent under this Indenture relating to the
satisfaction and discharge of this Indenture have been satisfied. 

        Notwithstanding
the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 7.07 and, if money shall have been deposited with the
Trustee pursuant to subclause (C) of Clause (ii) of this Section, the obligations of the Trustee under Section 11.02 shall survive. 

SECTION 11.02.    Application of Trust Funds  

        Subject to Section 11.03 hereof, all cash and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee
pursuant to Section 11.01 hereof in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to
the payment, either directly or through any Paying Agent 

78

 

(including
the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and
interest and Additional Interest, if any, but such cash and securities need not be segregated from other funds except to the extent required by law. 

SECTION 11.03.    Repayment to Company  

        Any cash or non-callable Government Securities deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment
of the principal of, premium, if any, or interest or Additional Interest, if any, on, any Note and remaining unclaimed for two years after such principal, and premium, if any, or interest or
Additional Interest, if any, has become due and payable shall be paid to the Company on its request or (if then held by the Company) shall be discharged from such trust; and the Holder shall
thereafter, as an unsecured creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such cash and securities, and all liability of
the Company as trustee thereof, shall thereupon cease; provided that the Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of the Company cause to be published once, in The New York Times and The Wall Street Journal (national edition), notice that such cash and securities remains unclaimed and that,
after a date specified therein, which shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such cash and securities then remaining will be
repaid to the Company. 

SECTION 11.04.    Reinstatement  

        If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable Government Securities in accordance with Sections 11.01
and 11.02, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company's and any
Guarantor's obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Sections 11.01 and 11.02 hereof until such time as the Trustee
or Paying Agent is permitted to apply all such money in accordance with Sections 11.01 and 11.02 hereof, as the case may be; provided that, if the
Company makes any payment of principal of, premium on, if any, or interest or Additional Interest, if any, on 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.

[FORM OF REVERSE OF NOTES]

111/2% Senior PIK Notes due 2015  

        Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 

        (1)   Interest. K&F Parent, Inc., a Delaware corporation (together with its permitted successors, the "Company"),
promises to pay interest on the principal amount of this Note at 111/2% per annum from February 11, 2005 until maturity and shall pay the Additional Interest, if any, payable
pursuant to Section 5 of the Registration Rights Agreement. The Company shall pay interest and Additional Interest, if any, semi-annually in arrears on February 1 and
August 1 of each such year, commencing                        , 20    or if any such day is not a
Business Day, on the next succeeding Business Day (each an "Interest Payment Date"). The
Company, at its option, shall be entitled to issue Additional PIK Notes under the Indenture as payment for accrued interest on the Notes in lieu of the payment of cash interest or Additional Interest.
Interest on the Notes shall accrue from the most recent date to which interest has been paid (whether in cash or in Additional PIK Notes) or, if no interest has been paid, from the date of
issuance[; provided that if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such
next succeeding Interest Payment Date]2. Interest shall be computed on the basis of a 360-day year of twelve 30-day months. 

        (2)   Method of Payment. The Company shall pay interest on the Notes (except defaulted interest) and Additional Interest, if
any, to the Persons in whose name(s) this Note (or one or more Predecessor Notes) is registered at the close of business on the January 15 or July 15 next preceding the Interest Payment
Date (each, a "Record Date"), even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.13 of the Indenture with
respect to defaulted interest. 

        The
Notes shall be payable as to principal of or premium (if any), Additional Interest (if any and if paid in cash), or interest (if paid in cash) at the office or agency of the Company
maintained for such purpose within or without the City and State of New York, or, at the option of the Company, payment of interest and Additional Interest, if any, may be made (i) by check
mailed to the Holders at their addresses set forth in the register of Holders or (ii) in the form of Additional PIK Notes to the accounts specified by DTC (or, if Notes are held in the form of
Definitive Notes, to the Holders by mail at their address set forth in the register of Holders); provided, payment by wire transfer of immediately
available funds shall be required with respect to principal of or premium (if any), Additional Interest (if any and if the Company elects to pay Additional Interest in cash), or interest (if the
Company elects to pay interest in cash) on, the Global Notes and all other Notes the Holders of which shall have provided wire transfer instructions to the Company or the Paying Agent prior to the
applicable Record Date. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. 

        (3)   Paying Agent and Registrar. Initially, U.S. Bank National Association, the Trustee under the Indenture, shall act as
Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity.

A-3

 

        (4)   Indenture. The Company issued the Notes under an Indenture, dated as of February 11, 2005 ("Indenture"), between
the Company and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code
§§ 77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any
provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are obligations of the Company initially in
the aggregate principal amount of $55,000,000. Subject to compliance with Section 2.16 of the Indenture, the Company is permitted to issue Additional Notes under the Indenture in an unlimited
principal amount. Any such Additional Notes that are actually issued shall be treated as issued and outstanding Notes (and as the same class as the Initial Notes) for all purposes of the Indenture,
unless the context clearly indicated otherwise. 

        (5)   Optional Redemption. 

        (a)   Except
as set forth in clause (b) of this Paragraph 5, the Company shall not have the option to redeem the Notes pursuant to Section 3.07 of the
Indenture prior to February 1, 2007. Thereafter, the Company shall have the option to redeem the Notes, in whole or in part, at the redemption prices (expressed as percentages of principal
amount) set forth below, plus accrued and unpaid interest and Additional Interest thereon, if any, to the applicable redemption date (subject to the right of Holders of record on the relevant record
date to receive interest due on the relevant interest payment date), if redeemed during the twelve-month period beginning on February 1 of the years indicated below: 

	Year
 
	 	Percentage

	2007	 	102.000%
	2008	 	101.000%
	2009 and thereafter	 	100.000%

        (b)   Notwithstanding
the provisions of clause (a) of this Paragraph 5, at any time prior to February 1, 2007, the Company may redeem (i) on any
one or more occasions up to 35% or (ii) 100% (but, other than as provided in the foregoing clause (i), not less than 100%) of the aggregate principal amount of Notes issued under this
Indenture (including any Additional PIK Notes and any Additional Notes) at a redemption price equal to 105.750% of the principal amount thereof on the redemption date, plus accrued and unpaid interest
and Additional Interest, if any, to the redemption date, with the net cash proceeds of one or more Equity Offerings by the Company; provided that
(1) in the case of a redemption pursuant to clause (i) above, at least 65% of the aggregate principal amount of Notes issued under this Indenture remains outstanding immediately after
the occurrence of such redemption (excluding Notes held by the Company and its Subsidiaries); and (2) that such redemption shall occur within 90 days of the date of the closing of such
Equity Offering. 

        (c)   On
and after the redemption date interest ceases to accrue on Notes or portions thereof called for redemption. 

        (6)   Repurchase at Option of Holder. 

        (a)   Upon
the occurrence of a Change of Control, each Holder of Notes shall have the right to require the Company to repurchase all or any part (equal to $1,000 or an
integral multiple of $1,000) of such Holder's Notes pursuant to the offer described below (the "Change of Control Offer") at an offer price in cash equal to 101% of the aggregate principal amount
thereof plus accrued and unpaid interest and Additional Interest, if any, thereon to the date of purchase (the "Change of Control Payment"). Within 30 days following any Change of Control, the
Company 

A-4

 

shall
mail a notice to each Holder setting forth the procedures governing the Change of Control Offer as required by the Indenture. 

        (b)   If
the Company or a Restricted Subsidiary consummates any Asset Sales, when the aggregate amount of Excess Proceeds exceeds $10 million, the Company or the
applicable Restricted Subsidiary shall commence an offer to all Holders pursuant to Section 4.10 of the Indenture to purchase the maximum principal amount of Notes (an "Asset Sale Offer") to
all Holders of Notes and all holders of such other Indebtedness of the Company that is pari passu with the Notes containing provisions similar to those
set forth in the Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets that may be purchased out of the Excess Proceeds, at an offer price in cash in an amount
equal to 100% of the principal amount thereof plus accrued and unpaid interest and Additional Interest, if any, thereon to the date of purchase, in accordance with the procedures set forth in the
Indenture. To the extent that any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use such Excess Proceeds for any purpose not otherwise prohibited by the Indenture.
If the aggregate principal amount of Notes and other pari passu Indebtedness tendered in such Asset Sale Offer exceeds the amount of Excess Proceeds,
the Excess Proceeds will be allocated by the Company to the Notes and such other pari passu Indebtedness on a pro rata basis (based upon the respective
principal amounts (or accreted value, if applicable) of the Notes and such other pari passu Indebtedness tendered into such Asset Sale Offer) and the
portion of each Note to be purchased will thereafter be determined by the Trustee on a pro rata basis among the Holders of such Notes with appropriate adjustments such that the Notes may only be
purchased in a minimum of $1,000 aggregate principal amount and integral multiples of $1.00 in excess thereof. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds shall be reset to
zero. Holders of Notes that are the subject of an offer to purchase shall receive an Asset Sale Offer from the Company prior to any related purchase date and may elect to have such Notes purchased by
completing the form entitled "Option of Holder to Elect Purchase" on the reverse of the Notes. 

        (7)   Notice of Redemption. Notice of redemption shall be mailed at least 30 days but not more than 60 days
before the redemption date to each Holder whose Notes are to be redeemed at its registered address. Notes in denominations larger than $1,000 may be redeemed in part but only in whole multiples of
$1,000, unless all of the Notes held by a Holder are to be redeemed on the basis of the aggregate principal amount (or accreted value, as applicable) of Notes and other pari
passu Indebtedness tendered. 

        (8)   Denominations, Transfer, Exchange. The Notes are in registered form without coupons in minimum denominations of $2,000
and integral multiples of $1,000 in excess thereof; provided, however, that Additional PIK Notes shall be issued in denominations of $1.00 and integral
multiples of $1.00. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and the Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Company need not exchange or register
the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, the Company need not exchange or register the
transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during the period between a record date and the corresponding Interest Payment Date. No service
charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection
therewith. 

        (9)   Persons Deemed Owners. The registered Holder of a Note may be treated as its owner for all purposes.

provision of the Indenture or the Notes (other than a Default or Event of Default in the payment of the principal of or premium, if any, Additional Interest, if any, or interest on the Notes) or
compliance with any provision of the Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes voting as a single class.
Without the consent of any Holder of a Note, the Indenture or the Notes may be amended or supplemented to cure any ambiguity, defect or inconsistency; provide for uncertificated Notes in addition to
or in place of certificated Notes (provided that the uncertificated Notes are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated

substantially all of the Company's assets; make any change that would provide any additional rights or benefits to the Holders of Notes or that does not adversely affect the rights under the Indenture
of any such Holder; provide for the issuance of Additional Notes in accordance with the provisions set forth in this Indenture; evidence and provide for the acceptance of an appointment of a successor
trustee; conform this Indenture or the Notes to the "Description of Notes" set forth in the Offering Memorandum; add Subsidiary Guarantees with respect to the Notes; or comply with requirements of the
Commission in order to effect or maintain the qualification of the indenture under the TIA. 

        (11) Events of Default. Events of Default include (1) default for 30 days in the payment when due of interest

borrowed of the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries) whether such Indebtedness or guarantee now
exists, or is created after the date of this Indenture, if that default: (a) is caused by a failure to pay at the final Stated Maturity the principal amount of such Indebtedness prior to the
expiration of the grace period provided in such Indebtedness on the date of such default (a "Payment Default"); or (b) results in the acceleration of such Indebtedness prior to its Stated
Maturity, and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the
maturity of which has been so accelerated, aggregates $15.0 million or more; (7) failure by the Company or any of its Subsidiaries to pay final judgments (not subject to appeal)
aggregating in excess of $15.0 million, which judgments are not paid, discharged or stayed within a period of 60 days after the date on which the right to appeal has expired;
(8) except as permitted by the Indenture, any Subsidiary Guarantee shall be held in any judicial proceeding to be unenforceable or invalid or shall cease for any reason to be in full force and
effect or any Guarantor, or any Person acting on behalf of any Guarantor, shall deny or disaffirm its obligations under its Subsidiary Guarantee; and (9) certain events of bankruptcy or
insolvency with respect to the Company or any of its Significant Subsidiaries or any group of Restricted Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary. If any Event of
Default (other than an Event of Default specified in clause (9) of this Paragraph 11) occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then
outstanding Notes may declare all the Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency
as specified in clause (9) of this Paragraph 11, all outstanding Notes shall become due and payable immediately without further 

A-6

 

action
or notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then
outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a
Default or Event of Default relating to the payment of principal or interest) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of
the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences under the Indenture, except a
continuing Default or Event of Default in the payment of interest or Additional Interest on, or the principal of, the Notes. The Company is required to deliver to the Trustee annually a statement
regarding compliance with the Indenture, and the Company is required upon becoming aware of any Event of Default, to deliver to the Trustee a statement specifying such Event of Default. 

        (12) Trustee Dealings with Company. The Trustee, in its individual or any other capacity, may make loans to, accept deposits
from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee. 

        (13) No Recourse Against Others. No director, officer, employee, incorporator, Affiliate or stockholder of the Company or any
of the Guarantors, as such, will have any liability for any obligations of the Company or such Guarantor under the Notes, the Indenture, the Subsidiary Guarantee, the Registration Rights Agreement or
for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are
part of the consideration for the issuance of the Notes. 

        (14) Authentication. This Note shall not be valid until authenticated by the manual signature of the Trustee or an
Authenticating Agent. 

        (15) Abbreviations. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM

        In
connection with our proposed purchase of $            aggregate principal amount of an 111/2% Senior PIK Notes due 2015 (the "Notes"), I hereby confirm that:

        1.     We
are an institutional "accredited investor" (as defined in Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act of 1933,
as amended (the "Securities Act")) and have such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of our investment in the Notes, and we
and any accounts for which we are acting are each able to bear the economic risk of our or its investment. 

        2.     We
are acquiring the Notes or beneficial interest therein for our own account or for one or more accounts (each of which is an "accredited investor") as to each of which
we exercise sole investment discretion. 

        3.     We
understand that any subsequent transfer of the Notes, or any interest therein is subject to certain restrictions and conditions set forth in the Notes and the
Indenture and the undersigned agrees to be bound by, and not to resell, pledge or otherwise transfer the Notes or any interest therein except in compliance with, such restrictions and conditions and
the Securities Act of 1933, as amended (the "Securities Act"). 

        4.     We
understand that the offer and sale of the Notes have not been registered under the Securities Act, and that the Notes and any interest therein may not be offered or
sold except as permitted in the following sentence. We agree, on our behalf and on behalf of any accounts for which we are acting, that if we should sell the Notes or any interest therein, we will do
so only (a) to the Company, (b) pursuant to a registration statement which has been declared effective under the Securities Act, (c) for so long as the Notes are eligible for
resale pursuant to Rule 144A, to a "Qualified Institutional Buyer" as defined in Rule 144A under the Securities Act that purchases for its own account or for the account of a Qualified
Institutional Buyer to whom notice is given that the transfer is being made in reliance on Rule 144A inside the United States, (d) pursuant to offers and sales to non-U.S.
persons that occur outside the United States within the meaning of Regulation S 

D-1

 

under
the Securities Act or (e) pursuant to any other available exemption from the registration requirements of the Securities Act, and we further agree to provide to any person purchasing a
Note from us in a transaction meeting the requirements of clauses (a) through (e) of this paragraph a notice advising such purchaser that resales thereof are restricted as stated
herein. 

        5.     We
understand that, on any proposed resale of the Notes or beneficial interest therein, we will be required to furnish to you and the Company such certifications, legal
opinions and other information as you and the Company may reasonably require to confirm that the proposed sale complies with the foregoing restrictions. We further understand that the Notes purchased
by us will bear a legend to the foregoing effect. 

        6.     We
are acquiring the Notes for investment purposes only with no present intention to resell the Notes, and agree not to sell, transfer, assign, pledge or hypothecate any
of the Notes for at least three months following the completion of the offering. 

        You
and the Company are entitled to rely upon this letter and are irrevocably authorized to produce this letter or a copy hereof to any interested party in any administrative or legal

lieu of, the terms of Sections 3, 4, 5, 6, 7 and 8 of this Agreement, each Securityholder agrees that, prior to making any Transfer of any Securities (other than a Transfer to the Company or to

of such proposed transferee and such other information as the Company may reasonably request. Each such Securityholder further agrees that such proposed Transfer will not be effected until: 

        (a)   the
Company has notified such Securityholder that either: 

        (i)    in
the opinion of Company counsel, no registration of such Securities under the Act is required in connection with such proposed Transfer; or 

        (ii)   a
registration statement under the Act covering such proposed disposition has been filed by the Company with the Commission and has become effective under the Act; and

with applicable state securities or "blue sky" laws has been effected. 

The
Company will use its best efforts to respond to any such notice from a Securityholder within ten (10) days of its receipt of such notice.

use reasonable efforts to comply with any such applicable state securities or "blue sky" 

9

 

laws,
but shall in no event be required, in connection therewith, to qualify to do business in any state where it is not then qualified or to take any action that would subject it to tax or to the
general service of process in any state where it is not then subject, unless the Company was otherwise required to do so prior to the proposed Transfer. The restrictions on Transfer contained in
Section 2.1 shall be in addition to, and not by way of limitation of, any other restrictions on Transfer contained in any other Section of this Agreement. 

        2.3    Rule 144 Acknowledgment.    Each Securityholder acknowledges that such Person is familiar with
Rule 144 of the Rules and Regulations of the Commission, as amended, promulgated pursuant to the Act ("Rule 144"), and that such Person
has been advised that Rule 144 permits, only under certain circumstances, the resale of restricted securities such as the Securities being purchased on the date hereof or that may become
subject hereto after the date hereof, but that Rule 144 is not currently, and may not in the future become, available to permit resales by such Person of any Securities. Each Securityholder
understands that, to the extent that Rule 144 is not available, such Person will be unable to sell any Securities without either registration under the Act or the existence of another exemption
from such registration requirement, and that the Company has no obligation whatsoever (except as set forth herein) to any Securityholder to register any Securities. 

        2.4    Restrictions on Transfer for Benefit of Securityholders.    Each Securityholder agrees that such Securityholder
will not Transfer any Securities (or any direct or indirect interest therein) or any stock certificate representing the same, now or hereafter at any time owned by such Securityholder, except

of the Qualified IPO Date such Securityholder will not Transfer any Securities now or hereafter owned by such Securityholder except to a Permitted Transferee or with the consent of the Aurora Entities
(which may be given or withheld in their respective sole and absolute discretion with or without any reason or liability therefor except as hereinafter provided in this Section 3). The
foregoing restriction shall be in addition to, and not in lieu of, the terms of Sections 2, 4, 5, 6, 7 and 8 of this Agreement. 

        3.2    Certain Releases Required.    Notwithstanding the provisions of the first sentence of Section 3.1, if

identified in Exhibit A or Exhibit B hereto as a Designated Securityholder and
(b) promptly after such Aurora Entity's receipt of a written request to do so from any such Designated Securityholder, given at any time or from time to time, such Aurora Entity shall consent
to the release from the terms of this Section 3 of the same proportion of such class of Securities which are then held subject to the terms of this Section 3 by such Designated
Securityholder as the number of shares of such class being distributed by the relevant Aurora Entity to its partners or members, as the case may be, bears to the total number of shares of such class
which would be distributed to such partners or members, as the case may be, if such Aurora Entity then distributed in kind all Securities of such class to its partners or members, as the case may be. 

        3.3    Certain Restrictions on Releases of Securities of Managing Directors.    No Aurora Entity may release any
Securities of a Managing Director from the restrictions imposed by this Section 3 or consent to the Transfer of any such Securities unless, in any such case, concurrent therewith such Aurora
Entity shall consent to the release from the terms of this Section 3 of the same proportion of such class of Securities subject to the terms of this Section 3 by each Securityholder as
the number of Securities of such class held by such Managing Director being released from such restrictions or being 

10

 

Transferred
bears to the total number of Securities of such class held by such Managing Director; provided,  however, that this sentence shall not apply (a) to any
Securities released from such restrictions pursuant to Section 3.2 or (b) to
Securities held by a Managing Director which are Transferred (i) to an Aurora Entity or any Affiliate thereof or (ii) to any other Person acceptable to the Aurora Entities if, in any
such case, the general partners and members of the Aurora Entities shall have determined that such Transfer is reasonably necessary to avoid financial or other hardship to such Managing Director. 

        3.4    Restriction on Transfer Subsequent to Qualified IPO Date.    Each Securityholder agrees that, without the
consent of a majority in interest of the Aurora Entities, after the occurrence of the Qualified IPO Date, such Securityholder will not effectuate any Transfer, or submit to any broker any sell order
with respect to a proposed Transfer, of Securities that would exceed the lesser of the volume limitations set forth in clauses (i), (ii) or (iii) of Rule 144(e)(1), regardless of
whether such Transfer or such Securities are otherwise subject to Rule 144; provided, however,
that the provisions of this Section 3.4 shall not apply with respect to any Transfer of Securities pursuant to an effective registration statement under the Act or pursuant to a
Tag-Along Sale pursuant to Section 6 of this Agreement. 

        4.    First Refusal Rights.    

        4.1    Restrictions Cumulative.    Each Securityholder agrees that such Securityholder will not Transfer any
Securities (or any direct or indirect interest therein) or any stock certificate representing the same, now or hereafter at any time owned by him, except to a Permitted Transferee or as required or
permitted by the provisions of Sections 2, 3, 4, 5 and 6 of this Agreement. The restrictions on transfer imposed by this Section 4 on any Securityholder shall be in addition to, and not in lieu
of, the restrictions on
transfer imposed by Sections 2, 3, 5, 6, 7 and 8 of this Agreement to the extent the same are otherwise applicable to such Securityholder. 

        4.2    Bona Fide Offers.    (a) If any Securityholder desires to Transfer any Securities (the
"Selling Securityholder") and such Selling Securityholder shall have received a bona fide arms'-length written offer (a "Bona
Fide Offer") from a Person other than an Affiliate or Associate of such Selling Securityholder (the "Outside Party") for the
Transfer of such Securities, such Selling Securityholder shall give written notice (the "Option Notice") to (i) each Qualifying Class B
Securityholder and (ii) the Company, setting forth such desire. The Option Notice shall set forth at least the name and address of the Outside Party and the price and terms of the Bona Fide
Offer and shall be accompanied by a copy of the Bona Fide Offer and reasonable evidence demonstrating the Outside Party's ability to consummate such offer. Upon the giving of such Option Notice, each
Qualifying Class B Securityholder shall have the option to purchase, on a Pro Rata basis, at the price offered by the Outside Party in the Bona Fide Offer, all or any portion of the Securities
specified in the Option Notice; provided, however, that in the event any Qualifying Class B
Securityholder does not elect to purchase all of its Pro Rata share of the Securities specified in the Option Notice and the other Qualifying Class B Securityholders elect to purchase all of
their respective Pro Rata share (the "Subscribing Parties"), then the Selling Securityholder shall provide a written notice (the
"Second Notice") to such Subscribing Parties and such Subscribing Parties shall have the option to purchase such unsubscribed shares subject to the
terms and conditions set forth in this Section 4.2. Said option to purchase shall be exercised within ten (10) Business Days following the giving of such Option Notice or within five
(5) Business Days following the giving of such Second Notice, as the case may be, by giving a counter-notice (a "Counter-Notice") to the Selling
Securityholder (with a copy of such Counter-Notice to the Company). In the event that a determination must be made (as described below) as to the fair market value of non-cash
consideration, the ten (10) Business Day period referred to in the immediately preceding sentence shall be extended to such greater period of time, not to exceed twenty (20) Business
Days after said Option Notice, specified in good faith by a disinterested majority of the Board. In the event that the Bona Fide Offer provides, in whole or in part, for non-cash
consideration, (i) the "price" offered by the 

11

 

Outside
Party shall be deemed to be the amount of cash, if any, provided in the Bona Fide Offer plus the fair market value of the non-cash consideration as determined in good faith by a
disinterested majority of the Board, and (ii) the Qualifying Class B Securityholders shall be entitled to pay such "price" in the same ratio of cash and non-cash
consideration provided in such Bona Fide Offer, with the fair market value of the non-cash consideration provided by the Qualifying Class B Securityholders determined in good faith
by a disinterested majority of the Board. 

        Notwithstanding
the foregoing, the Qualifying Class B Securityholders shall not be permitted to purchase any Securities from GEPT pursuant to this Section 4 if such
purchase would constitute a non-exempt prohibited transaction under ERISA. 

        (b)   Subject
to paragraph (d) of this Section 4.2, if any of the Qualifying Class B Securityholders elect to purchase such Securities, each such electing
entity shall be obligated to purchase, at the price and on substantially the same terms as offered by the Outside Party in the Bona Fide Offer, and such Selling Securityholder shall be obligated to
sell, such Securities at a closing to be held on the fifteenth (15th) Business Day after the giving of the Counter-Notice at the principal executive offices of the Company, or at such other time and
place as may be mutually acceptable to each purchasing entity, and such Selling Securityholder; provided, that such purchasing Qualifying Class B
Securityholders shall agree in advance of such purchase to continue to be designated as a Securityholder and to be bound by the terms of this Agreement pursuant to a written agreement reasonably
satisfactory to the Company and the Aurora Entities with respect to such purchased Securities. The closing of any such purchase may be delayed, at the election of the purchasing entity, up to thirty
(30) Business Days in order to permit such acquisition of such Securities to be made in conformity with applicable laws, including the HSR Act. 

        (c)   Subject
to paragraph (d) of this Section 4.2, if the Qualifying Class B Securityholders do not elect to purchase all of such Securities proposed to
be sold by such Selling Securityholder within the time limits specified in paragraph (a) of this Section 4.2, then the Company shall have the option, exercisable by the delivery of a
counter-notice to such Selling Securityholder no later than fifteen (15) Business Days following the date of the Option Notice, to purchase, at the price and on substantially the same terms as
offered by the Outside Party in the Bona Fide Offer, all or any portion of the Securities specified in the Option Notice and not purchased by the Qualifying Class B Securityholders. In the
event that the Company elects to purchase Securities pursuant to this Section 4.2(c), the Company will be obligated to purchase, and such Selling Securityholder shall be obligated to sell, such
Securities at a closing to be held on the fifteenth (15th) Business Day after the delivery of the Company's counter-notice to such Selling Securityholder at the principal executive offices of the
Company, or at such other time and place as may be mutually acceptable to the Company and such Selling Securityholder. The closing of any such purchase by the Company may, at the election of the
Company, be delayed up to thirty (30) Business Days in order to permit such acquisition of such Securities to be made in conformity with applicable laws, including the HSR Act. Notwithstanding
the foregoing, the Company shall not be permitted to purchase any Securities from GEPT pursuant to this Section 4 if such purchase would constitute a non-exempt prohibited
transaction under ERISA. 

        (d)   If
the Qualifying Class B Securityholders and the Company do not in the aggregate elect to purchase all of the Securities subject to the Bona Fide Offer within
the time limits specified above, then the offer to sell any of the Securities to the Qualifying Class B Securityholders and the Company shall be deemed revoked and the Selling Securityholder,
at any time within a period of three months from the giving of said Option Notice, may Transfer all (but not less than all) of the remainder of such Securities to the Outside Party at a price and on
terms not less favorable than those contained in the Bona Fide Offer; provided, that such Outside Party shall agree in advance of such Transfer to be
designated as a Securityholder and to be bound by the terms of this Agreement pursuant to a written agreement reasonably satisfactory to the Company and the Aurora Entities;  provided, further however, 

12

 

that
in the event such Selling Securityholder has not so Transferred said Securities to the Outside Party within said three month period, then said Securities thereafter shall continue to be subject
to all of the restrictions contained in this Agreement as though no Option Notice had ever been given. 

        (e)   At
the closing of any purchase of Securities pursuant to this Section 4.2, the Selling Securityholder shall deliver certificates representing such Securities duly
endorsed for transfer and accompanied by all requisite stock transfer taxes. Any Securities purchased pursuant to this Section 4.2 shall be free and clear of any and all Liens (other than those
arising under this Agreement) and at the Closing of the purchase the Selling Securityholder shall represent and warrant to such effect and to the effect that such Selling Securityholder is the
beneficial owner of such Securities. The Person making such purchase shall deliver at such closing, by certified or bank check, payment in full for the Securities being purchased by such Person. At
such closing, all of the parties to the transaction shall execute such additional documents as are otherwise reasonably necessary or appropriate, consistent with the terms hereof, including without
limitation, a written agreement reasonably satisfactory to the Company and the Aurora Entities providing for the purchasing Qualifying Class B Securityholder and/or the Outside Party, as the
case may be, to be designated as a Securityholder and be bound by the terms of this Agreement. 

        (f)    If,
in any instance, the Qualifying Class B Securityholders or the Company elects not to exercise its rights hereunder or elects to waive such rights, such
election shall not constitute a waiver of such Person's rights to receive an Option Notice in the case of any Transfer subsequently proposed by such or any other Securityholder. 

        4.3    Involuntary Transfers.    (a) Each Securityholder shall notify the Company and the Qualifying
Class B Securityholders promptly upon the occurrence of an Involuntary Transfer of any Securities (including Involuntary Transfers of any beneficial interest by a Beneficial Owner). If an
Involuntary Transfer of any of the Securities owned by any Securityholder shall occur, the Qualifying Class B Securityholders and the Company shall have the same rights of first refusal under
Section 4.2 above with respect thereto (the "Transferred Securities") as if the Involuntary Transfer had been a proposed voluntary Transfer by
such Securityholder, except that: 

        (i)    the
periods within which such rights must be exercised shall run from the date notice of the Involuntary Transfer is received from the Securityholder or its legal
representatives with respect to which such Involuntary Transfer has occurred; and 

        (ii)   such
rights shall be exercised by notice (an "Involuntary Transfer Notice") to the Involuntary Transferee rather than to
the Securityholder with respect to which such Involuntary Transfer has occurred. 

If
such Transferred Securities were shares of Common Stock or Preferred Stock, the purchase price thereof shall be the lesser of the Fair Market Value of such Transferred Securities on the date of
such Involuntary Transfer or on the date of the relevant Involuntary Transfer Notice from the Securityholder from whom such Involuntary Transfer took place (or from such Involuntary Transferee). If
such Transferred Securities are Options or Warrants that are then exercisable, the purchase price thereof shall be equal to (i) the lesser of (y) the aggregate Fair Market Value on the
date of such Involuntary Transfer of the number of shares of Common Stock which the holder of such Options or Warrants is entitled to receive upon exercise of such Transferred Securities or
(z) the aggregate Fair Market Value of such number of shares on the date of the relevant Involuntary Transfer Notice from the Securityholder from whom such Involuntary Transfer took place (or
from such Involuntary Transferee), less (ii) the aggregate exercise price of such Transferred Securities, but not less than zero. If such Transferred Securities are Options or Warrants that are
not then exercisable, the purchase price thereof shall be as set forth in the immediately preceding sentence after such appropriate discount for the fact that such Transferred Securities are not then
exercisable as may be determined by the Board, in good faith and in the exercise of business judgment. 

13

 

        (b)   At
the closing of any purchase of Transferred Securities, the Involuntary Transferee shall deliver certificates representing the Transferred Securities being purchased
by the Qualifying Class B Securityholders or the Company, as the case may be, duly endorsed for transfer and accompanied by all requisite stock transfer taxes. Such Transferred Securities shall
be transferred free and clear of any and all Liens arising through the action or inaction of the Involuntary Transferee (other than those arising under this Agreement) and the Involuntary Transferee
shall represent and warrant to such effect and to the effect that such Involuntary Transferee is the beneficial owner of such Transferred Securities. At the closing of any such purchase, the
Securityholder that was the transferor in respect of the Involuntary Transfer shall represent and warrant to the purchaser or purchasers that such Securityholder had conveyed to the Involuntary
Transferee good and valid title to the Transferred Securities. The Person making such purchase shall deliver at closing, by a certified or bank check, payment in full of the purchase price for the
Transferred Securities being purchased by such Person. At such closing, all of the parties to the transaction shall execute such additional documents as are otherwise necessary or appropriate,
including without limitation, a written agreement reasonably satisfactory to the Company and the Aurora Entities providing for the purchasing Qualifying Class B Securityholder to continue to be
designated as a Securityholder and be bound by the terms of this Agreement with respect to the Transferred Securities. 

        (c)   In
the event that the provisions of this Section 4.3 shall be held to be unenforceable with respect to any particular Involuntary Transfer of Securities, the
Qualifying Class B Securityholders and the Company shall have a right of first refusal as set forth in Section 4.2 hereof if the Involuntary Transferee subsequently obtains a Bona Fide
Offer for and desires to Transfer such Transferred Securities. 

        4.4    Application of First Refusal Rights.    The first refusal rights provided in Sections 4.2 and 4.3 shall not
apply to any Transfer of Securities: 

        (a)   to
the Company, or to a Permitted Transferee of the relevant Securityholder; 

        (b)   to
a Class B Securityholder by any Associate or Affiliate of any Class B Securityholder; 

        (c)   pursuant
to an effective registration statement under the Act or pursuant to Rule 144; 

        (d)   to
an Other Securityholder (as defined in Section 6.1) pursuant to Section 6 below; or 

        (e)   by
a Drag-Along Securityholder (as defined in Section 5.1) pursuant to Section 5 below. 

        4.5    Termination of First Refusal Rights.    Notwithstanding anything herein to the contrary, the rights of first
refusal provided in this Section 4 shall terminate, with respect to all Securities held by each Securityholder, upon the occurrence of the Qualified IPO Date. 

        5.    Third-Party Offer for All Outstanding Securities.    

        5.1    "Drag-Along" Obligations.    If the Aurora Entities shall receive an offer in writing from an
Independent Third Party (a "Third-Party Offeror") to purchase all of the issued and outstanding Securities held by such Aurora Entities, to effect a
business combination of the Company with such Person or an Affiliate thereof or to purchase all or substantially all the assets of the Company (each an "Acquisition
Proposal"), and the Aurora Entities desire to accept or cause the Company to accept such Acquisition Proposal, the Aurora Entities shall deliver a notice (an
"Acquisition Notice") to the Company (which shall deliver a copy of such Acquisition Notice to each of the other Securityholders within three
(3) Business Days of its receipt thereof). Such Acquisition Notice shall contain a copy of such Acquisition Proposal, including the name and address of the Third-Party Offeror and the terms of
the Acquisition Proposal. If any other Securityholder receives any Acquisition Proposal (which, for this purpose, includes an offer to purchase all of the issued and outstanding Common Stock and any
other securities exercisable for or convertible into Common Stock but not an offer to purchase only such other Securityholder's Common Stock and any other securities exercisable for or convertible
into 

14

 

Common
Stock), such Securityholder shall promptly transmit such Acquisition Proposal to the Company and each Aurora Entity (which the Aurora Entities may elect not to pursue without any liability or
obligation to any Securityholder or the Company). The other Securityholders (the "Drag-Along Securityholders") severally agree that, upon
receipt of such Acquisition Notice, they shall be obligated to sell, at the same time the Aurora Entities sell, all of their Securities to the Third-Party Offeror upon the terms and conditions set
forth in the Acquisition Proposal, or, as the case may be, to vote their Securities in favor of the merger or sale of all or substantially all of the assets of the Company as described in the
Acquisition Proposal, and otherwise to take all actions reasonably necessary or appropriate to cause the Company to consummate the proposed transaction. In any such transaction, all of such shares of
Common Stock shall be purchased at, or be converted into the right to receive, the same price per share of Common Stock as received by the Aurora Entities and all of such shares of Preferred Stock
shall be purchased at, or be converted into the right to receive, the same price per share of Preferred Stock as received by the Aurora Entities and the terms and conditions of such sale shall be the
same terms and conditions for all Securityholders, including the Aurora Entities. To the extent that the Securityholders (or any successors thereto) are to provide any indemnification or otherwise
assume any other post-closing liabilities with respect to the Company or any of its subsidiaries or with respect to any breach of representations or warranties of the Company or any of its
subsidiaries, the Aurora Entities and all other Securityholders selling Securities in a transaction under this Section 5 shall do so severally and not jointly (and on a pro rata basis in
accordance with the aggregate consideration payable to the Aurora Entities and such other Securityholders with respect to the shares of Common Stock being sold by each of the Aurora Entities and such
other Securityholder). Notwithstanding anything to the contrary set forth herein, each other Securityholder may be required to give customary representations and warranties as to its Securities,
including, but not limited to, title to Securities conveyed by it, its legal authority and capacity, and non-contravention of other agreements to which it is a party. The potential
liability of each such other Securityholder in the immediately preceding two sentences may not exceed the net proceeds received by such Securityholder. Furthermore, in connection with such transaction
no Securityholder (in his capacity as a Securityholder) shall be required to enter into any non-competition agreement. Notwithstanding the foregoing, any Securityholder that is subject to
ERISA shall not be obligated to sell any Securities to any Third-Party Offeror pursuant to this Section 5 if such sale would constitute a non-exempt prohibited transaction under
ERISA. In that regard, the Aurora Entities may, in their sole discretion and at their own expense, seek an administrative exemption from the U.S. Department of Labor (or other appropriate governmental
agency) to allow such sale. 

        5.2    Termination of Drag-Along Obligations.    Notwithstanding anything herein to the contrary, the
rights and obligations provided for in this Section 5 shall terminate, with respect to all Securities held by any Securityholder, upon the occurrence of the Qualified IPO Date. 

        5.3    Restrictions Cumulative.    The restrictions on transfer imposed by this Section 5 on any Securityholder
shall be in addition to, and not in lieu of, the restrictions on transfer imposed by Sections 2, 3, 4, 6, 7 and 8 of this Agreement to the extent the same are otherwise applicable to such
Securityholder. 

        6.    "Tag-Along" Rights.    

        6.1    "Tag-Along" Sales.    If any Class B Securityholder (for purposes of this Section 6,
respectively the "Proposed Transferor") at any time or from time to time, in one transaction or in a series of related transactions, desires to enter
into an agreement (whether oral or written) to Transfer (for purposes of this Section 6, a "Tag-Along Sale") shares of Common Stock
and/or Preferred Stock to any Person, then each of the other Securityholders (including, without limitation, the other Class B Securityholders) (for purposes of this Section 6,
collectively, the "Other Securityholders") shall have the right, but not the 

15

 

obligation,
to elect that the Proposed Transferor be obligated to require, as a condition to such Tag-Along Sale, that the proposed purchaser purchase from each such electing Other
Securityholder: 

        (a)   up
to the number of shares of Common Stock derived by multiplying the total number of shares of Common Stock owned by or issuable to such electing Other Securityholder
by a fraction, the numerator of which is equal to the number of shares of Common Stock then owned by or issuable to the Proposed Transferor that are to be purchased by the proposed purchaser (without
giving effect to any reduction in such number of shares by reason of any Other Securityholder's election to exercise the "tag-along" rights provided in this Section 6 in connection
with such transaction) and the denominator of which is the total number of shares of Common Stock owned by or issuable to the Proposed Transferor prior to such sale; and/or 

        (b)   up
to the number of shares of the applicable series of Preferred Stock subject to the Tag-Along Sale having an aggregate redemption value equal to the amount
derived by multiplying the aggregate redemption value of all the shares of the applicable series of Preferred Stock subject to the Tag-Along Sale owned by or issuable to such electing
Other Securityholder times a fraction, the numerator of which is equal to the aggregate redemption value of all the shares of the applicable series of Preferred Stock subject to the
Tag-Along Sale then owned by or issuable to the Proposed Transferor that are to be purchased by the proposed purchaser (without giving effect to any reduction in such number of shares by
reason of any Other Securityholder's election to exercise the "tag-along" rights provided in this Section 6 in connection with such transaction) and the denominator of which is the
aggregate redemption value of all the shares of the applicable series of Preferred Stock subject to the Tag-Along Sale owned by or issuable to the Proposed Transferor prior to such sale; 

provided, however, that if any Other Securityholder chooses not to sell any or all Securities which such
Other Securityholder may be entitled to sell under this Section 6.1, the Proposed Transferor may sell, in the same transaction, (x) additional shares of Common Stock equal to the
difference between the number of shares of Common Stock which such Other Securityholder is entitled to sell and the number of shares of Common Stock such Other Securityholder chooses to sell, if any,
and (y) additional shares of the applicable series of Preferred Stock subject to the Tag-Along Sale equal to the difference between the number of shares of the applicable series of
Preferred Stock subject to the Tag-Along Sale which such Other Securityholder is entitled to sell and the number of shares of the applicable series of Preferred Stock subject to the
Tag-Along Sale such Other Securityholder chooses to sell. Any such sales by any Other Securityholder shall be on the same terms and conditions as the proposed Tag-Along Sale by
the Proposed Transferor. Each Other Securityholder whose Securities are sold in a Tag-Along Sale shall be required to bear a proportionate share of the reasonable expenses of the
transaction, including, without limitation, legal, accounting and investment banking fees and expenses. 

        6.2    Notice of Tag-Along Opportunity.    The Proposed Transferor participating in a
Tag-Along Sale shall promptly (and in no event less than twenty (20) Business Days prior to the consummation thereof) provide the Company with notice (for purposes of this
Section 6, the "Proposed Transferor Notice") of the proposed Tag-Along Sale (which the Company shall transmit to each Other
Securityholder within three (3) Business Days after its receipt thereof) containing the following: 

        (a)   the
name and address of the proposed transferee of the Securities in the Tag-Along Sale; 

        (b)   the
number of shares of Common Stock and each series of Preferred Stock proposed to be Transferred by the Proposed Transferor in the event none of the Other
Securityholders elects to participate; 

        (c)   the
proposed amount and form of consideration to be paid for such Securities and the terms and conditions of payment offered by the proposed transferee; 

16

 

        (d)   the
aggregate number of shares of Common Stock and each series of Preferred Stock held of record by such Proposed Transferor as of the date of the notice (for purposes
of this Section 6, "Notice Date") from the Proposed Transferor to the Company; 

        (e)   the
aggregate number of shares of Common Stock and each series of Preferred Stock held of record as of the Notice Date by all Other Securityholders as a group; 

        (f)    the
maximum number of shares of Common Stock and each series of Preferred Stock each such Other Securityholder is entitled to include in the Tag-Along Sale
(as computed in accordance with the equations set forth in Section 6.1); and 

        (g)   that
the proposed transferee has been informed of the "tag-along" rights provided for in Section 6.1. 

        6.3    Notice and Terms of Acceptance of Tag-Along Opportunity.    

        (a)   If
an Other Securityholder desires to participate in such Tag-Along Sale, such Other Securityholder shall provide written notice (the "Tag-Along
Notice") to such Proposed Transferor not later than ten (10) Business Days after the Notice Date setting forth the number of shares of Common Stock and each series of Preferred Stock, if any,
such Other Securityholder elects to include in the Tag-Along Sale. 

        (b)   Any
Other Securityholder who at the time of a Proposed Transferor Notice then owns Preferred Stock of any series as well as Common Stock and/or Preferred Stock of any
other series may elect to include Preferred Stock of such first series in a Tag-Along Sale (if shares of Preferred Stock of such series are to be transferred by the Proposed Transferor in
such Tag-Along Sales) only if the Preferred Stock of such series to be transferred by such Other Securityholder represents a percentage of the Preferred Stock of such series then owned by
such Other Securityholder at least equal to the greatest percentage of the Common Stock or any series of Preferred Stock having a liquidation preference or preference as to dividends that is junior to
such series of Preferred Stock that is to be transferred by such Other Securityholder in such Tag-Along Sale. 

        (c)   The
Tag-Along Notice given by any Other Securityholder shall constitute such Other Securityholder's binding agreement to sell such Securities as are included
therein on the terms and conditions applicable to such sale (including the requirements of this Section 6), in which case the number of shares of Common Stock and/or Preferred Stock to be
Transferred by the Proposed Transferor shall be correspondingly reduced. In the event that the proposed transferee does not purchase the Securities of the Proposed Transferor, then the proposed
Tag-Along Sale by the Other Securityholders to such proposed transferee shall not take place. If the Tag-Along Notice from any Other Securityholder is not received by the
Proposed Transferor within the ten (10) Business Day period specified above in this Section 6.3, the Proposed Transferor shall have the right to transfer the Securities of Common Stock
and/or Preferred Stock to the proposed transferee without any participation by such Other Securityholder, but only on the terms and conditions stated in the notice to such Other Securityholders or on
terms and conditions no more favorable to the Proposed Transferor and only if a definitive and binding agreement to sell or otherwise transfer such Securities is entered into not later than thirty
(30) days after the end of such ten (10) Business Day period specified above in this Section 6.3. 

        6.4    Application of Tag-Along Provisions.    The provisions of this Section 6 shall not apply to: 

        (a)   any
transaction in which shares of Common Stock or Preferred Stock are proposed to be sold publicly pursuant to a registration statement filed under the Act or pursuant
to Rule 144; 

        (b)   any
Transfer to a Permitted Transferee; 

17

 

        (c)   any
one transaction or series of related transactions involving the Transfer (other than to a Permitted Transferee) by the Proposed Transferor of less than 1% of the
issued and outstanding shares of Common Stock or less than 1% of the issued and outstanding shares of Preferred Stock of any series; 

        (d)   any
shares of Common Stock or Preferred Stock proposed to be Transferred by the Proposed Transferor which are purchased by the Company or any Other Securityholder
pursuant to Section 4; or 

        (e)   any
Transfer of shares of Common Stock in connection with an Acquisition Proposal subject to the provisions of Section 5 hereof. 

        6.5    Termination of Tag-Along Rights.    Notwithstanding anything herein to the contrary, the rights and
obligations provided for in this Section 6 shall terminate, with respect to all Securities held by each Other Securityholder, upon the occurrence of the Qualified IPO Date. 

        6.6    Restrictions Cumulative.    The restrictions on transfer imposed by this Section 6 on any Securityholder
shall be in addition to, and not in lieu of, the restrictions on transfer imposed by Sections 2, 3, 4, 5, 7 and 8 of this Agreement to the extent the same are otherwise applicable to such
Securityholder. 

        7.    Certain Voting Agreements.    

        7.1    Grant of Irrevocable Proxy.    Each Securityholder (other than GEPT, CalPERS and CDP) hereby irrevocably
appoints the Aurora Entities, and each of them acting alone (with full power of substitution), as such Securityholder's proxy and attorney in fact (each, in such capacity, a
"Proxy Holder") to vote and to give or withhold consent with respect to all shares of Common Stock and Preferred Stock (if any such rights exists), held
by such Securityholder from time to time in such manner as such Proxy Holder or Proxy Holders shall determine in their respective sole and absolute discretion, at any meeting (whether annual or
special and whether or not an adjourned meeting) of the Company or by written consent or otherwise, giving and granting to the Proxy Holders all powers such Securityholder would possess if personally
present and hereby ratifying and confirming all that said Proxy Holders or either shall lawfully do or cause to be done by virtue hereof, provided,
however, that the foregoing proxy shall not apply to any action to be taken or consent to be given by any such Securityholder, in its capacity as such, under the terms of
Sections 12 and 13.2 of this Agreement or with respect to matters of the type described in Section 7.2(b), (c), (d), (e) and (f) and provided,
further, that the Aurora Entities shall be prohibited from using any of such proxies to amend the terms and conditions set forth in Sections 12 and 13.2 hereof. No Proxy Holder
shall have any liability to any Securityholder as a result of any action taken or failure to take action pursuant to the foregoing proxy except for any action or failure to take action not taken or
omitted in good faith or which involves gross negligence, intentional misconduct or a knowing violation of applicable law. Each such Securityholder represents that any proxies heretofore given by such
Securityholder, in respect of its Securities are not irrevocable; any such prior proxies are hereby revoked. Each such Securityholder hereby affirms that this irrevocable proxy is given in
consideration for the mutual agreements contained in this Agreement and in connection with such Securityholder's subscription for its Securities and constitutes a material inducement to the Company
and the Aurora Entities to approve such subscription, and that this irrevocable proxy is coupled with an interest and may, under no circumstances, be revoked. The Company hereby acknowledges receipt
of and the validity of the foregoing irrevocable proxy, and agrees to recognize the Proxy Holders as the sole attorneys and proxies for each such Securityholder at all times prior to the termination
date of such irrevocable proxy as hereinafter provided in this Section 7.1. Each such Securityholder intends that this irrevocable proxy is executed and intended to be irrevocable in accordance
with the provisions of Section 212 of the Delaware General Corporation Law to the extent that the same is or may be applicable. The proxy granted by this Section 7.1 shall terminate with
respect to any share of Common Stock or Preferred 

18

 

Stock
held by any such Securityholder only at such time as such share is no longer owned beneficially or of record by such Securityholder, any of his, her or its respective Permitted Transferees or
any other Person designated a Securityholder and bound by the terms of this Agreement. 

        7.2    Agreement of CalPERS, GEPT and CDP.    Each of CalPERS, GEPT and CDP hereby irrevocably agrees, with respect to
any matter, to vote and to give or withhold consent with respect to all shares of Common Stock and Preferred Stock held by CalPERS, GEPT or CDP, as the case may be, as a Securityholder from time to
time in such manner as the Aurora Entities shall vote or give or withhold consent with respect to such matter; provided however, that CalPERS, GEPT or
CDP, as the case may be, shall not be so obligated to so vote or give or withhold consent with respect to any matter to the extent that it reasonably believes, based upon written advice of counsel,
that: 

        (a)   solely
in the case of GEPT, to the extent that GEPT's fiduciary duties under ERISA shall require otherwise; 

        (b)   such
matter relates to or would constitute a violation or breach of any covenant, agreement or representation or warranty by any Aurora Entity or any of its Affiliates
(other than the Company or any of its controlled Affiliates) contained in this Securityholders Agreement or the Management Services Agreement; 

        (c)   such
matter constitutes fraud by, gross negligence of, willful misconduct or malfeasance of, a felony or willful violation of law or admission or a violation of any
federal or state securities laws (including a consent or plea of no contest or consent to a permanent injunction prohibiting future violations) by any Aurora Entity or any of its Affiliates (other
than the Company or any of its controlled Affiliates); 

        (d)   the
taking of such action (i) is not within the scope of CalPERS', GEPT's or CDP's, as the case may be, authority as a stockholder of the Company or
(ii) would constitute a breach or disregard of CalPERS', GEPT's or CDP's, as the case may be, fiduciary duties to the other stockholders of the Company or (iii) would constitute a
violation by CalPERS, GEPT or CDP, as the case may be, of laws and regulations and rules having the force of law applicable to CalPERS, GEPT or CDP, as the case may be; 

        (e)   such
matter or action relates to the bankruptcy or insolvency of the Company or any of its subsidiaries; or 

        (f)    such
matter relates to the conduct of any Aurora Entity or any of its Affiliates (other than the Company or any of its controlled Affiliates) that would have the effect
of releasing any such Aurora Entity or any of its Affiliates, as the case may be, from liability if CalPERS, GEPT or CDP, as the case may be, reasonably believes, based upon written advice of counsel,
that such conduct was taken in bad faith or in a manner reasonably believed by such Aurora Entity or any of its Affiliates, as the case may be, to be not in, or opposed to, the best interest of the
Company. 

        Provided further, that the foregoing shall not apply to any action to be taken or consent to be given by CalPERS, GEPT or CDP, as the case
may be, in its capacity as a Securityholder, under the terms of Sections 12 and 13.2 of this Agreement. Each of CalPERS, GEPT and CDP represents that it has not heretofore given any proxies or
otherwise agreed to vote in respect of its Securities, and agrees that so long as such Securities are subject to this Section 7.2, it will not grant any proxy to any Person or otherwise agree
to vote in conflict with the provisions of this Section 7.2. Each of CalPERS, GEPT and CDP hereby affirms that its agreement to vote its Securities set forth in this Section 7.2 is given
in consideration for the mutual agreements contained in this Agreement and in connection with its subscription for its Securities and constitutes a material inducement to the Company and the Aurora
Entities to approve such subscription, and that this agreement to vote is coupled with an interest and may, under no circumstances, be revoked. The agreement set forth in this Section 7.2 shall
terminate with respect to each Security only at such time as such Security is no longer owned beneficially or of 

19

 

record
by CalPERS, GEPT or CDP, as the case may be, or any of their respective Permitted Transferees or any other Person designated a Securityholder and bound by the terms of this Agreement. 

        8.    Call Upon the Occurrence of Certain Events.    

        8.1    Joint Call by the Aurora Entities.    If (i) any Class A Securityholder is employed by the
Company or any of its direct or indirect Subsidiaries or (ii) any Class A Securityholder is a consultant to the Company or any of its direct or indirect Subsidiaries, and such employment
or consulting relationship shall, during the Call Period, be terminated by the Company for Cause or be voluntarily terminated by such Class A Securityholder (in either case, a
"Call Event"), then the Aurora Entities shall have the option to purchase (the "Call Option") on a Pro
Rata basis as among the Aurora Entities, at the Per Share Call Price, and such Class A Securityholder shall be required to sell, all or any portion of the Securities held by such Class A
Securityholder (collectively, the "Call Securities"), such option to be exercised within sixty (60) days after the Call Event by the giving of an
exercise notice (the "Aurora Call Notice") to such Class A Securityholder (with a copy of such Aurora Call Notice to the Company). 

        8.2    Closing of Joint Call by the Aurora Entities.    Subject to Section 8.4, if either or all Aurora
Entities elect to purchase such Call Securities, each such purchasing entity shall be obligated to purchase, and such Class A Securityholder shall be obligated to sell, such Call Securities at
a closing to be held on the fifteenth (15th) Business Day after the giving of the Aurora Call Notice at the principal executive offices of the Company, or at such other time and place as may be
mutually acceptable to each such purchasing entity and such selling Class A Securityholder. The closing of any such purchase by an Aurora Entity may, at the election of the purchasing Aurora
Entity, be delayed up to thirty (30) Business Days in order to permit such acquisition of such Call Securities to be made in conformity with applicable laws, including the HSR Act. 

        8.3    Call by the Company.    Subject to Section 8.4, if the Aurora Entities do not elect to purchase all of
such Call Securities within the time limits specified in Section 8.1, then the Company shall have the option,
exercisable by the delivery of an exercise notice (the "Company Call Notice") to such Class A Securityholder no later than fifteen
(15) Business Days following the date of expiration of the sixty (60) day period specified in Section 8.1, to purchase, at the Per Share Call Price, all or any portion of the Call
Securities specified in the Call Option and not purchased by the Aurora Entities. In the event that the Company elects to purchase the Call Securities pursuant to this Section 8.3, the Company
will be obligated to purchase, and such Class A Securityholder shall be obligated to sell, such Call Securities at a closing to be held on the fifteenth (15th) Business Day after the delivery
of the Company Call Notice to such Class A Securityholder at the principal executive offices of the Company, or at such other time and place as may be mutually acceptable to the Company and
such selling Class A Securityholder. The closing of any such purchase by the Company may, at the election of the Company, be delayed up to thirty (30) Business Days in order to permit
such acquisition of such Call Securities to be made in conformity with applicable laws, including the HSR Act. 

        8.4    Non-Exercise of Call.    If the Aurora Entities and the Company elect not to purchase all of the
Call Securities subject to the Call Event within the time limits specified above, then the sale of the Call Securities to the Aurora Entities and/or the Company shall be deemed revoked. 

        8.5    Closing Mechanics.    At the closing of any purchase of Call Securities pursuant to this Section 8, the
selling Class A Securityholder shall deliver certificates representing such Call Securities duly endorsed for transfer and accompanied by all requisite stock transfer taxes. Any Call Securities
purchased pursuant to this Section 8 shall be transferred free and clear of any and all Liens (other than those arising under this Agreement) and at the Closing of the purchase the selling
Class A Securityholder shall represent and warrant to such effect and to the effect that such selling Class A Securityholder is the beneficial owner of such Call Securities. The Person
making such purchase shall 

20

 

deliver
at such closing, by certified or bank check, payment in full for the Call Securities being purchased by such Person. At such closing, all of the parties to the transaction shall execute such
additional documents as are otherwise reasonably necessary or appropriate, consistent with the terms hereof. 

        9.    Registration Rights.    

        The
Company agrees to afford to each Eligible Holder the registration rights set forth in Exhibit C hereto and each party hereby
agrees to be bound by the terms and conditions included in Exhibit C hereto as if such terms and conditions were included in the body of this
Agreement. 

        10.    Right of First Offer.    

        10.1    Right of First Offer.    Subject to the terms and conditions contained in this Section 10, the Company
grants to each Class B Securityholder the right of first offer to purchase such Securityholder's Pro-Rata Portion (as defined below) of any New Securities (as defined below), that
the Company or any of its Subsidiaries may, from time to time, propose to sell and issue (the "Right of First Offer"). A Class B Securityholder's
"Pro Rata Portion" in respect of any New Securities shall be the ratio that (x) the sum of the number of shares of Common Stock then held by such
Securityholder or issuable to such Securityholder bears to (y) the sum of the aggregate number of shares of Common Stock then outstanding, in each case calculated on a fully-diluted basis.
Subject to the terms and conditions contained in this Section 10, any portion of the New Securities not purchased pursuant to the Right of First Offer may be sold to any other Person. 

        10.2    Definition of New Securities.    Except as set forth below, "New
Securities" shall mean any shares of capital stock of the Company or any of its Subsidiaries, including Common Stock or Preferred Stock, whether authorized or not, and rights,
options or warrants to purchase shares of capital stock of the Company or any of its Subsidiaries, and securities of any type whatsoever that are, or may become, convertible into said shares of
capital stock of the Company or any of its Subsidiaries, issued after the date hereof. Notwithstanding the foregoing, "New Securities" does not include
(i) the Senior Preferred, the Senior Redeemable Preferred Stock of K&F Intermediate Holdco, Inc. or the Senior Redeemable Preferred Stock of K&F Acquisition, Inc.;
(ii) shares of Common Stock or Series A Preferred to be issued by the Company concurrently with the execution of this Agreement; (iii) securities offered to the public generally
pursuant to a registration statement under the Securities Act; (iv) securities issued in connection with the acquisition of another corporation by the Company by merger, purchase of all or
substantially all of the assets or shares or other reorganization whereby the Company or its stockholders own not less than a majority of the voting power of the surviving or successor corporation,  provided such transaction is approved by the Board in accordance with the Certificate of Incorporation of the Company as then in effect; (v) any
shares of Common Stock or common stock of the Subsidiaries of the Company or related options convertible into or exercisable for such Common Stock or common stock issued to employees, officers and
directors of, and consultants to, the Company or any of its Subsidiaries, pursuant to any of the Company's or any of its Subsidiaries' option plan or plans,  provided that such shares of common stock
shall not exceed the number of shares allocated or reserved for issuance under the Company's or any of its
Subsidiaries' option plan or plans (subject to appropriate adjustment for stock splits, stock dividends, combinations, recapitalizations and the like); (vi) securities issued in connection with
any stock split, stock dividend or recapitalization by the Company or any of its Subsidiaries; (vii) shares of Common Stock and Series A Preferred to be issued by the Company, from time
to time but by no later than June 30, 2005, directly or indirectly, on substantially the same terms and conditions as the shares of Common Stock and Series A Preferred to be issued by
the Company concurrently with the execution of this Agreement, to the directors, officers, employees of or consultants to the Company or any of its Affiliates; and (viii) shares of Common Stock
and Series A Preferred to be issued by the Company, from time to time but by no later than June 30, 2005, on substantially the same terms and conditions as the shares of Common Stock and
Series A 

21

 

Preferred
to be issued by the Company concurrently with the execution of this Agreement, to any limited partner of Aurora Equity Partners III L.P. or any Affiliate of such limited partner. 

        10.3    Notice of Right.    In the event the Company proposes to undertake an issuance of New Securities, it shall
give to each Class B Securityholder written notice of its intention, describing the type of New
Securities and the price and terms upon which the Company proposes to issue the same and, if available, the definitive documents for such a financing (a "Financing
Notice"). Each Class B Securityholder shall have ten (10) Business Days from the date of receipt of any such Financing Notice to agree to purchase its Pro Rata
Portion of such New Securities for the price and upon the terms specified in the notice, by giving written notice to the Company and stating therein the quantity of New Securities to be purchased (the
"Election Notice"). 

        10.4    Exercise of Right.    If any Class B Securityholder exercises its Right of First Offer hereunder, the
closing of the purchase of the New Securities with respect to which such right has been exercised shall take place within fifteen (15) Business Days after such Class B Securityholder
gives notice of such exercise, which period of time may be delayed up to thirty (30) Business Days in order to permit such acquisition of such New Securities to be made in conformity with
applicable laws, including the HSR Act. Upon exercise of such Right of First Offer, the Company and such Class B Securityholder shall be legally obligated to consummate the purchase
contemplated thereby and shall use their best efforts to secure any approvals required in connection therewith. 

        10.5    Lapse and Reinstatement of Right.    In the event any Class B Securityholder fails to exercise the
Right of First Offer provided in this Section 10 within said ten (10) Business Day period, then any other Class B Securityholder that elects to purchase all of its Pro Rata
Portion of the New Securities in said ten (10) Business Day period shall have the option to purchase such unsubscribed shares of New Securities on the same terms and conditions set forth in
this Section 10 within fifteen (15) Business Days after such Class B Securityholder receives notice from the Company of such unsubscribed shares, which period of time may be
delayed up to thirty (30) Business Days in order to permit such acquisition of such New Securities to be made in conformity with applicable laws, including the HSR Act. In the event any
Class B Securityholder fails to exercise the Right of First Offer provided in this Section 10 to purchase all of the New Securities set forth in the Financing Notice within said ten
(10) Business Day period, the Company shall have a period of three (3) months thereafter to sell or enter into an agreement (pursuant to which the sale of New Securities covered thereby
shall be closed, if at all, within thirty (30) Business Days from the date of said agreement) to sell the New Securities not elected to be purchased by such Class B Securityholder at the
price and upon terms no less favorable to the Company than those contained in the Financing Notice. In the event the Company has not sold the New Securities or entered into an agreement to sell the
New Securities within said three (3) month period (or sold and issued New Securities in accordance with the foregoing within thirty (30) Business Days from the date of said agreement),
the Company shall not thereafter issue or sell any New Securities without first offering such securities to each Class B Securityholder as provided in Section 10.1 above. 

        10.6    Termination of Right.    Notwithstanding anything herein to the contrary, the rights and obligations provided
in this Section 10 shall terminate upon the occurrence of a Qualified IPO. 

        11.    Information Rights; Access Rights and Board Observer Rights.    

        11.1    Information Rights.    

        (a)   Subject

Company and its subsidiaries, and (iv) notice of any event of default on any Material Debt (as defined in the Certificate of Incorporation of the Company, as amended from time to time). 

        (b)   Subject
to the terms and conditions set forth herein, if K&F Industries is not required to file the materials and information set forth in clause (a) above with
the Commission pursuant to the Exchange Act or does not otherwise file such materials and information with the Commission, each Class B Securityholder will have rights to receive (i) as
soon as available, but in any event within forty-five (45) days after the end of each fiscal quarter of K&F Industries, Inc., copies of the consolidated balance sheets of K&F
Industries, Inc. and its subsidiaries as at the end of such quarter, and consolidated statements of income, stockholders' equity and cash flows of K&F Industries, Inc. and its
subsidiaries, for such quarter and for the portion of the fiscal year ending with such quarter, in each case prepared in accordance with GAAP applicable to periodic financial statements generally,
subject to changes resulting from normal year-end adjustments and (ii) as soon as available, but in any event within ninety (90) days after the end of each fiscal year of K&F
Industries, Inc., copies of the consolidated balance sheets of K&F Industries, Inc. and its subsidiaries as at the end of such year, and consolidated statements of income, stockholders'
equity and cash flows of K&F Industries, Inc. and its subsidiaries for such year, in each case prepared in accordance with GAAP applicable to periodic financial statements generally, and
accompanied by an opinion thereon of independent certified public accountants of recognized national standing, which opinion shall state that such financial statements present fairly, in all material
respects, the financial position of the Persons being reported upon and their results of operations and cash flows and have been prepared in conformity with GAAP, (iii) the annual consolidated
business plan of the Company and its subsidiaries, and (iv) notice of any event of default on any Material Debt (as defined in the Certificate of Incorporation of the Company, as amended from
time to time). 

        (c)   Each
Class B Securityholder's rights under this Section 11.1 are conditioned upon and subject to such Class B Securityholder agreeing in writing
pursuant to a confidentiality and nondisclosure agreement, in form and substance reasonably acceptable to the Company and its counsel, prior to being furnished any information pursuant to this
Section 11.1, to hold in confidence and trust and not use or disclose any confidential information provided to or learned by it in connection with its rights under this Agreement during the
time such Class B Securityholder has the information rights set forth in this Section 11.1 and thereafter. 

        11.2    Access Rights.    Each Class B Securityholder will have access, during normal business hours, to the
facilities, records and personnel (including outside accountants) of the Company and its subsidiaries to the extent that the same reasonably relates to such Class B Securityholder's interest in
the Company, subject to reasonable prior written notice delivered to the Company and subject to execution and delivery of a confidentiality and nondisclosure agreement in form and substance reasonably
acceptable to the Company and its counsel. The Company shall be entitled to designate one or more representatives of the Company to be present during all such periods of access. 

        11.3    Board Observer Rights.    Each Qualifying Class B Securityholder will have the right to send one
non-voting representative on its behalf (the "Observer") to attend all meetings of the Board, including all committees thereof, solely in a
non-voting observer capacity; provided, however, that each such Observer shall be reasonably
acceptable to a majority of the members of the Board elected by the holders of the Common Stock. The Company will furnish to the Observer copies of all notices, minutes, consents, board package
materials and other materials that it generally makes available to its directors as and when such materials are provided to its directors. The Observer may participate in 

23

 

discussions
of matters under consideration by the Board and any matters brought before any committee thereof but will not be entitled to vote on any matter presented to the Board;  provided, however, that a majority of the Board shall have the right, after deliberation in a closed
session in which they can exclude the Observer, to exclude the Observer from portions of meetings of the Board or any committee thereof or omit to provide the Observer with certain information to the
extent that a majority of the members of the Board believe in good faith after consultation with counsel that such exclusion or omission is necessary in order to preserve any attorney-client
privilege, attorney-work product privilege or other similar legal privileges or such attendance or distribution of materials is otherwise prohibited by applicable law;  provided, further, however, that the Observer shall
agree in writing pursuant to a confidentiality and nondisclosure agreement, prior to attending any such meetings or to being furnished any such written materials, to hold in confidence and trust and
not use or disclose any confidential information provided to or learned by him in connection with his rights under this Agreement during the time the Observer has observation rights and thereafter.
Each Qualifying Class B Securityholder will have the right to remove and replace its Observer in its sole discretion and to designate a substitute representative if such Observer is unable or
unwilling to attend any of the Board's meetings, including any committees thereof. Each Qualifying Class B Securityholder shall be solely responsible for any expenses or charges incurred by its
Observer in the performance of its duties as an Observer pursuant to this Section 11.3. 

        12.    Termination.    

        Except
for the provisions of Sections 9 and 13, which shall survive the expiration or other termination of this Agreement, this Agreement shall terminate upon the written approval of
(i) the Company, (ii) the Aurora Entities, (iii) the holders of at least 662/3% in voting interest of the issued and outstanding shares of Common Stock, voting
together as a single class and each such share being entitled to one vote per share, held by all the Securityholders other than the Aurora Entities and (iv) the holders of at least
662/3%
in voting interest of the issued and outstanding shares of the Series A Preferred, voting together as a single class and each such share being entitled to one vote per share, held by all the
Securityholders other than the Aurora Entities; provided, that any termination that would adversely affect the rights of any Securityholder (other than
any termination that would adversely affect the rights of all Securityholders in the same manner) under this Agreement must be consented to by such Securityholder before such termination may be deemed
effective against such Securityholder. A Securityholder shall cease to be deemed a Securityholder hereunder, and shall no longer be a party to this Agreement, at such time as such Securityholder
ceases to own any Securities. 

        13.    Miscellaneous.    

        13.1    Governing Law.    This Agreement shall be governed by and construed and enforced in accordance with the
internal laws of the State of Delaware without regard to principles of conflicts of law. 

        13.2    Entire Agreement; Amendments.    This Agreement (including the exhibits hereto) constitutes the entire

and provided, further that no amendment shall be made to Sections 4, 5, 6, 9, 10, 11, 12 or 13.2
hereof without the consent of (h) the holders of at least 662/3% in voting interest of the issued and outstanding shares of Common Stock, voting together as a single class and
each such share being entitled to one vote per share, held by all the Securityholders other than the Aurora Entities or their Affiliates and (i) the holders of at least 662/3% in
voting interest of the issued and outstanding shares of Preferred Stock, voting together as a single class and each such share being entitled to one vote per share, held by all the Securityholders

liability of any Securityholder in respect of representations or indemnification made pursuant to Section 5 or (ii) require such Securityholder to provide any guarantee for the benefit

Securityholder or group of Securityholders (other than any amendment that would adversely affect the rights of all Securityholders in the same manner) under this Agreement must be consented to by such
Securityholder or group of Securityholders before such amendment may be deemed effective against such Securityholder or group of Securityholders. Notwithstanding the foregoing, subject to the
subscription rights set forth in Section 10 and subject to any limitations set forth in its Amended and Restated Certificate of Incorporation or Bylaws, the Company shall have the right, from
and after the date hereof, in the sole discretion of the Board, to issue shares of Common Stock or Preferred Stock, or Options or Warrants to purchase or securities convertible into such shares, to
any Person (whether or not such Person is already party to this Agreement) and to cause such securities and such Persons (to the extent not already subject to this Agreement) to become subject to this
Agreement (including, at the option of the Company, the designation of any of such securities as Registrable Securities) and as a Securityholder of whatever class as the Company may determine,
respectively. 

        13.3    Legend on Stock Certificates.    Each certificate representing Securities which are subject to this Agreement
shall be endorsed with a legend substantially to the following effect (in addition to any legend required by applicable state securities or "blue sky" laws): 

THE
SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR UNDER THE SECURITIES LAWS OF ANY STATE AND MAY NOT BE SOLD, TRANSFERRED OR
OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER THAT ACT AND UNDER APPLICABLE STATE SECURITIES LAWS OR K&F PARENT, INC. (THE "COMPANY") SHALL HAVE
RECEIVED AN OPINION OF ITS COUNSEL THAT REGISTRATION OF SUCH SECURITIES UNDER THAT ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE SECURITIES LAWS IS NOT REQUIRED. THE SALE, TRANSFER OR OTHER
DISPOSITION OF THE SECURITIES IS ALSO SUBJECT TO COMPLIANCE WITH THE TERMS AND CONDITIONS OF THAT CERTAIN SECURITYHOLDERS AGREEMENT, DATED AS OF NOVEMBER 18, 2004, AS SUPPLEMENTED, MODIFIED AND
AMENDED FROM TIME TO TIME, AMONG THE COMPANY AND THE STOCKHOLDERS, OPTIONHOLDERS AND WARRANTHOLDERS SIGNATORY THERETO, A COPY OF WHICH AGREEMENT IS AVAILABLE FOR INSPECTION DURING REGULAR BUSINESS
HOURS AT THE PRINCIPAL EXECUTIVE OFFICES OF THE COMPANY. 

Any
stock certificate issued at any time in exchange or substitution for any certificate bearing such legend (except a new certificate issued upon the completion of a public distribution of securities
of the Company represented thereby) shall also bear such legend, unless the restrictions contained in Sections 3, 4, 5, 6, 7, 8 and 9 of this Agreement are no longer in effect and, in the opinion of
counsel for the Company, the Securities represented thereby need no longer be subject to the restrictions contained in 

25

 

Section 2
of this Agreement. The provisions of this Agreement shall be binding upon, and shall inure to the benefit of, the Securityholders and all subsequent holders of Securities who acquired
the same directly or indirectly from a Securityholder in a transaction or series of transactions not involving any public offering. The Company agrees that it will not transfer on its books any
certificate representing Securities in violation of the provisions of this Agreement. 

        13.4    Specific Performance.    Due to the fact that the securities of the Company cannot be readily purchased or
sold in the open market, and for other reasons, the parties will be irreparably damaged in the event that this Agreement is not specifically enforced. In the event of a breach or threatened breach of
the terms, covenants and/or conditions of this Agreement by any of the parties hereto, the other parties shall, in addition to all other remedies, be entitled (without any bond or other security being
required) to a temporary and/or permanent injunction, without showing any actual damage or that monetary damages would not provide an adequate remedy, and/or a decree for specific performance, in
accordance with the provisions hereof. 

        13.5    Waiver.    No waiver of any breach or default hereunder shall be considered valid unless in writing, and no
such waiver shall be deemed a waiver of any subsequent breach or default of the same or similar nature. Anything in this Agreement to the contrary notwithstanding, any waiver, consent or other
instrument under or pursuant to this Agreement signed by, or binding upon, a Securityholder shall be valid and binding upon any and all persons or entities (other than the Company) who may, at any
time, have or claim any rights under or pursuant to this Agreement in respect of the Securities originally acquired by such Securityholder. 

        13.6    Successors and Assigns.    Except as otherwise expressly provided herein, this Agreement shall be binding upon
and inure to the benefit of the Company, its successors and assigns, and the Securityholders and their respective heirs, personal representatives, successors and permitted assigns. 

        13.7    Severability.    If any provision of this Agreement shall be invalid or unenforceable, such invalidity or
unenforceability shall attach only to such provision and shall not in any manner affect or render invalid or unenforceable any other severable provision of this Agreement, and this Agreement shall be
carried out as if any such invalid or unenforceable provision were not contained herein. 

        13.8    Headings.    The section headings contained herein are for the purposes of convenience of reference only and
are not intended to define or limit the contents of said sections. 

        13.9    Further Assurances.    Each party hereto shall cooperate and shall take such further action and shall execute

        13.13    Arbitration.    

        (a)   Any
disputes or differences between the parties arising out of this Agreement which the parties are unable to resolve themselves shall be submitted to and resolved by
arbitration as herein provided. Within ten (10) Business Days after commencement of arbitration in accordance with the rules then obtaining of the American Arbitration Association, any of the
parties hereto in dispute may request the American Arbitration Association to designate one arbitrator, who shall be a retired or former judge of any appellate court of the State of California, any
United States appellate court or the United States District Court for any California District who is, in any such case, not affiliated with any party in interest to such arbitration and who has
substantial professional experience with regard to corporate legal matters. 

        (b)   The
arbitrator shall consider the dispute at issue at Los Angeles, California at a mutually agreed upon time within thirty (30) days (or such longer period as may
be acceptable to the parties hereto in dispute) of the designation of the arbitrator. The arbitration proceeding shall be held in accordance with the rules for commercial arbitration of the American
Arbitration Association in effect on the date of commencement of such arbitration and shall include an opportunity for the parties to conduct discovery in advance of the proceeding. Notwithstanding
the foregoing, the parties hereto agree that they will attempt, and they intend that they and the arbitrator should use their best efforts in that attempt, to conclude the arbitration proceeding and
have a final decision from the arbitrator within ninety (90) days from the date of selection of the arbitrator; provided, however, that the
arbitrator shall be entitled to extend such ninety (90) day period one or more times to the extent necessary for such arbitrator to place a dollar value on any claim that may be unliquidated.
The arbitrator shall promptly deliver a decision with respect to the dispute to each of the parties, who shall promptly act in accordance therewith. Each party to such arbitration agrees that any
decision of the arbitrator shall be final, conclusive and binding and that they will not contest any action by any other party thereto in accordance with a decision of the arbitrator. It is
specifically understood and agreed that any party may enforce any award rendered pursuant to the arbitration provisions of this Section 13.13 by bringing suit in any court of competent
jurisdiction. The parties hereto agree that the arbitrator shall have authority to grant injunctive or other forms of equitable relief to any party that prevails in any such arbitration. 

        (c)   All
costs and expenses attributable to the arbitrator shall be allocated among the parties to the arbitration in such manner as the arbitrator shall determine to be
appropriate under the circumstances. 

        13.14    Effective Date.    The effective date of this Agreement shall be the Initial Date, and each reference herein
to the date of this Agreement shall be deemed to be a reference to the Initial Date. 

        13.15    GEPT Liability.    Any monetary obligation or liability of GEPT under this Agreement shall be enforced solely
against the Securities then held by GEPT and not against the other assets of GEPT and not against the Trustees of GEPT or General Electric Company or any affiliate thereof or the assets thereof.

   EXHIBIT C  

Registration Rights  

        1.    "Piggy-Back" Registration.    

        (a)    Right to Include Registrable Securities.    If the Company at any time following a Qualified IPO, proposes to
register any of its equity securities under the Act (other than by a registration on Form S-4 or Form S-8 or any successor or similar forms), whether or not for
sale for its own account, in a manner which would permit registration of Registrable Securities for sale to the public under the Act, then the Company will each such time give prompt written notice
(which shall be at least thirty (30) days prior to filing) to all Eligible Holders of Registrable Securities of its intention to do so, of such Eligible Holders' rights under this
Paragraph 1 and, to the extent such information is available, of the type and number of equity securities to be registered, the distribution arrangements and if the offering is underwritten the
proposed price and identity of the lead underwriter(s). Upon the written request of any such Eligible Holder made within twenty (20) days after the receipt of any such notice (which request
shall specify the Registrable Securities intended to be disposed of by such Eligible Holder), the Company will use its best efforts to effect the registration under the Act of all Registrable
Securities which the Company has been so requested to register by the holders thereof, to the extent required to permit the disposition (in accordance with the intended methods thereof as aforesaid)
of the Registrable Securities so to be registered, by inclusion of such Registrable Securities in the registration statement which covers the securities which the Company proposes to register or in a
separate registration statement concurrently filed and on terms substantially the same as those being offered to the Company; provided, however, that
if, at any time after giving written notice of its intention to register any securities and prior to the effective date of the registration statement filed in connection with such registration, the
Company shall determine for any reason not to register or to delay registration of such securities, the Company may, at its election, give written notice of such determination to each Eligible Holder
of Registrable Securities and, thereupon: 

        (i)    in
the case of a determination not to register, shall be relieved of its obligation to register any Registrable Securities in connection with such registration (but not
from its obligation to pay the Registration Expenses in connection therewith), and 

        (ii)   in
the case of a delay in registering, shall be permitted to delay registering any Registrable Securities for the same period as the delay in registering such other
securities. 

        (b)    Priority in "Piggy-Back" Registrations.    If a registration pursuant to this Paragraph 1
involves an underwritten offering and the managing underwriter advises the Company in writing that, in its opinion, the number of securities requested to be included in such registration exceeds the
number which can be sold in such offering without adversely affecting the offering, the Company will include in such registration to the extent of the number which the Company is so advised can be
sold in such offering without adversely affecting the offering, securities determined as follows: 

        (i)    first,
the securities proposed by the Company to be sold for its own account, 

        (ii)   second,
any Registrable Securities requested to be included in such registration pro rata among the holders thereof
requesting such registration on the basis of the number of shares of such securities requested to be included by such holders, and 

        (iii)  third,
any other securities of the Company proposed to be included in such registration statement in accordance with the priorities, if any, then existing among the
holders of such securities. 

C-1

 

        2.    Demand Registration Right of Certain Securityholders.    

        (a)    Right to Require Registration.    Subject to the provisions of this Paragraph 2, at any time after the
date 6 months following a Qualified IPO, any Holder of 10% or more of the outstanding Common Stock (a "Demand Holder") shall have the right to
require the Company to file a registration statement under the Securities Act for a public offering of all or any portion of the Registrable Securities held by such Holder when such right is
exercised (the shares subject to the demand, the "Registration Demand Securities"), provided that any
request for a Demand Registration (as defined below) shall not be otherwise deemed to be effective unless such request is with respect to Registrable Securities constituting at least five percent (5%)
of the outstanding shares of the class of Registrable Securities. The demand registration rights granted to the Demand Holders in this Paragraph 2 are subject to the following limitations:
(i) each Demand Holder may make a demand under this Paragraph 2 only two
(2) times (a "Demand Registration"); (ii) the Company shall not be obligated to cause any registration statement filed under this
Paragraph 2 to be declared effective less than six months after the effective date of the most recent registration statement filed by the Company on its own behalf; (iii) the managing
underwriter of any such offering shall be a nationally recognized investment banking firm selected by the Company and approved by the Demand Holder making the Demand Registration (which approval shall
not be unreasonably withheld); (iv) notwithstanding the giving of notice by a Demand Holder of the exercise of its right to require registration under this Paragraph 2, the Company may
elect to convert such registration into a registration of shares for sale by the Company pursuant to Paragraph 1 hereof by providing notice to the Securityholders in accordance with
Paragraph 1, and in such event the provisions of Paragraph 1 shall apply to such registration rather than the provisions of this Paragraph 2 and such registration shall not count
as a Demand Registration; (v) during any two-year period, the Company may make a one-time election to postpone the filing or the effectiveness of a registration
statement for a Demand Registration for up to six months if the Board determines, in its good faith judgment, that (x) such Demand Registration would reasonably be expected to have an adverse
effect on, interfere with or delay any proposal or plan by the Company or any of its subsidiaries to engage in any acquisition of assets (other than in the ordinary course of business) or any merger,
consolidation, tender offer or similar transaction, (y) the filing of a registration statement or a sale of Registrable Securities pursuant thereto would require disclosure of material
information that the Company has a bona fide business purpose for preserving as confidential or (z) the Company is unable to comply with the registration requirements of the Commission;  provided,
that, in such event, the holders of Registrable Securities initially requesting such Demand Registration will be entitled to withdraw such
request and, if such request is withdrawn, such request for Demand Registration will not count as a request for Demand Registration hereunder and the Company will pay all Registration Expenses in
connection with such withdrawn registration request; and (vi) any demand under this Paragraph 2 shall be for a firm commitment underwritten offering, with respect to which the Company
shall be required to maintain an effective registration statement for a maximum of 90 days. 

        (b)    Notice of Exercise of Demand Registration Right; Participation Rights.    Any Demand Holder shall provide
written notice to the Company of the Demand Registration (which notice shall state the number of shares of Registrable Securities the Demand Holder desires the Company to register and the intended
method of disposition of such securities), and the Company promptly shall provide written notice of such Demand Registration to all of the other Securityholders and all of the Securityholders then
will have the opportunity to include in the offering shares of Registrable Securities then owned by such Securityholders, but in each case only to the extent permitted by Paragraph 2(c) below.
In addition, subject to Paragraph 2(c) below, the Company may elect to include in any registration statement and offering pursuant to this Paragraph 2 newly issued shares of Registrable
Securities. Solely for purposes of Paragraphs 3 

C-2

 

through
9 below, any securities registered pursuant to this Paragraph 2 shall be deemed to be Registrable Securities. 

        (c)    Priority.    Notwithstanding the foregoing, if the registration pursuant to this Paragraph 2 involves an
underwritten offering and the managing underwriter advises the Company in writing that the number of shares of Registrable Securities desired to be offered by the Company or Securityholders other than
the Demand Holder (the "Other Sellers") together with the Registration Demand Securities of the Demand Holder exceeds the maximum number of such shares
which the managing underwriter considers, in
good faith, to be appropriate based on market conditions and other relevant factors (including, without limitation, pricing) (the "Maximum Number"),
then the securities proposed to be included by the Company shall be excluded from such registration before any such securities of the Demand Holder or the Other Sellers. If, and to the extent that,
after exclusion of the securities proposed to be included by the Company, the Registration Demand Securities proposed to be included by the Demand Holder and the securities proposed to be included by
the Other Sellers exceeds the Maximum Number, then the Registration Demand Securities proposed to be included by the Demand Holder and the securities proposed to be included by the Other Sellers that
may be included in the underwriting shall be allocated among all Securityholders thereof, including the Demand Holder, in proportion (as nearly as practicable) to the amount of Registrable Securities
owned by each Securityholder; provided, however, that the number of Registration Demand Securities to be
included in such underwriting is not reduced below thirty-five percent (35%) percent of the aggregate number of Registration Demand Securities for which inclusion has been requested by the
Demand Holder. Each of the Demand Holder, the Other Sellers and the Company (in the event that any securities are to be offered by the Company) may withdraw from any demand registration pursuant to
this Paragraph 2 by giving written notice to the Company prior to the effective date of such registration statement and, in the event of a withdrawal by the Demand Holder, such withdrawn Demand
Registration shall not be deemed to be a Demand Registration counting against the maximum of two Demand Registrations set forth in Paragraph 2(a) if the Demand Holder pays or promptly
reimburses the Company for all Registration Expenses incurred by the Company in connection with such withdrawn Demand Registration. 

        3.    Registration Procedures.    If and whenever the Company is required to use its best efforts to effect the
registration of any Registrable Securities under the Act as provided in Paragraph 1 or 2, the Company will, subject to the terms and conditions of Paragraph 1 or 2: 

        (a)   prepare
and file with the Commission as expeditiously as possible (and, in any event, within ninety (90) days), the requisite registration statement to effect
such registration and use its best efforts to cause such registration statement to become effective; provided, however, that as provided in
Paragraph 1 and 2 hereof, the Company may discontinue any registration of its securities at any time prior to the effective date of the registration statement relating thereto; 

        (b)   prepare
and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary
to keep such registration statement effective and to comply with the provisions of the Act with respect to the disposition of all securities covered by such registration statement until the earlier of
such time as all of such securities have been disposed of in accordance with the intended methods of disposition by the seller or sellers thereof set forth in such registration statement or the
expiration of ninety (90) days after such registration statement becomes effective; provided,  however, that if less than all the Registrable
Securities are withdrawn from registration after the expiration of such period, the shares so withdrawn
shall be allocated pro rata among the holders thereof on the basis of the respective numbers of Registrable Securities held by them included in such
registration; 

C-3

 

        (c)   promptly
furnish to each seller of Registrable Securities covered by such registration statement such number of conformed copies of such registration statement and of
each such amendment and supplement thereto (in each case including all exhibits), such number of copies of the prospectus contained in such registration statement (including each preliminary
prospectus and any summary prospectus) and any other prospectus filed under Rule 424 under the Act, in conformity with the requirements of the Act, and such other documents as such seller may
reasonably request; 

        (d)   use
its best efforts to register or qualify, prior to the effective date of such registration, all Registrable Securities and other securities covered by such
registration statement under such securities or blue sky laws of such jurisdictions as each seller thereof shall reasonably request, to keep such registration or qualification in effect for so long as
such registration statement remains in effect, and take any other action which may be reasonably necessary or advisable to enable such seller to consummate the disposition in such jurisdictions of the
securities owned by such seller, except that the Company shall not for any such purpose be required to: 

        (i)    qualify
generally to do business as a foreign corporation in any jurisdiction wherein it would not but for the requirements of this Paragraph 2(d) be obligated to
be so qualified, 

        (ii)   subject
itself to taxation in any such jurisdiction, or 

        (iii)  consent
to general service of process in any such jurisdiction; 

        (e)   use
its best efforts to cause, prior to the effective date of such registration statement, all Registrable Securities covered by such registration statement to be
registered with or approved by such other governmental agencies or authorities as may be necessary to enable the seller or sellers thereof to consummate the disposition of such Registrable Securities; 

        (f)    furnish
to each seller of Registrable Securities covered by such registration statement a signed counterpart, addressed to such seller (and the underwriters, if any),
of: 

        (i)    an
opinion of counsel for the Company, dated the effective date of such registration statement (or, if such registration includes an underwritten public offering, an
opinion of counsel for the Company dated the date of the closing under the underwriting agreement), reasonably satisfactory in form and substance to such seller, and 

        (ii)   a
"comfort" letter, dated the effective date of such registration statement (and, if such registration includes an underwritten public offering, a "comfort" letter
dated the date of the closing under the
underwriting agreement), signed by the independent public accountants who have certified the Company's financial statements included in such registration statement, 

covering
substantially the same matters with respect to such registration statement (and the prospectus included therein) and, in the case of the accountants' letter, with respect to events subsequent
to the date of such financial statements, as are customarily covered in opinions of issuer's counsel and in accountants' letters delivered to the underwriters in underwritten public offerings of
securities and, in the case of the accountants' letter, such other financial matters as such seller or such holder (or the underwriters, if any) may reasonably request; 

        (g)   immediately
notify each holder of Registrable Securities covered by such registration statement, at any time when a prospectus relating thereto is required to be
delivered under the Act, of the happening of any event or the existence of any condition as a result of which the prospectus included in such registration statement, as then in effect, includes an
untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under
which they were made, or if in the opinion of counsel for the Company it is necessary to supplement or amend such prospectus to comply with law and, at the request of any such holder promptly 

C-4

 

prepare
and furnish to such holder a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such
securities, such prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not
misleading in light of the circumstances under which they were made or such prospectus, as supplemented or amended, shall comply with law; 

        (h)   otherwise
use its best efforts to comply with all applicable rules and regulations of the Commission, and make available to its security holders, as soon as reasonably
practicable, an earnings statement covering the period of at least twelve (12) months, but not more than eighteen (18) months, beginning with the first full calendar month after the
effective date of such registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Act and the rules and regulations of the Commission thereunder, and
not file any amendment or supplement to such registration statement or prospectus to which any such seller of Registrable Securities covered by such registration statement shall have reasonably
objected on the grounds that such amendment or supplement does not comply in all material respects with the requirements of the Act or of the rules or regulations thereunder, having been furnished
with a copy thereof at least five (5) business days prior to the filing thereof; 

        (i)    provide
a transfer agent and registrar for all Registrable Securities covered by such registration statement not later than the effective date of such registration
statement; 

        (j)    use
its best efforts to list, not later than the effective date of such registration statement, all Registrable Securities covered by such registration statement on any
securities exchange on which any of the Registrable Securities are then listed or any other trading market on which any of the Registrable Securities are then admitted for trading; and 

        (k)   pay
all Registration Expenses relating to any such registration. 

The
Company may require each seller of Registrable Securities as to which any registration is being effected to furnish the Company with such information and undertakings as it may reasonably request
regarding such seller and the distribution of such securities as the Company may from time to time reasonably request in writing. 

        Each
holder of Registrable Securities agrees by acquisition of such Registrable Securities as follows: 

        (A)  that
upon receipt of any notice from the Company of the happening of any event of the kind described in Paragraph 3(g), such holder will forthwith discontinue
such holder's disposition of Registrable Securities pursuant to the registration statement relating to such Registrable Securities until such holder's receipt of the copies of the supplemented or
amended prospectus contemplated by Paragraph 3(g) and, if so directed by the Company, will deliver to the Company (at the Company's expense) all copies, other than permanent file copies, then
in such holder's possession of the prospectus relating to such Registrable Securities current at the time of receipt of such notice, and 

        (B)  that
it will immediately notify the Company, at any time when a prospectus relating to the registration of such Registrable Securities is required to be delivered under
the Act, of the happening of any event as a result of which information previously furnished by such holder to the Company in writing for inclusion in such prospectus contains an untrue statement of a
material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made. 

In
the event the Company or any such holder shall give any such notice, the period referred to in Paragraph 3(h) shall be extended by a number of days equal to the number of days during the
period 

C-5

 

from
and including the giving of notice pursuant to Paragraph 3(g) to and including the date when each seller of any Registrable Securities covered by such registration statement shall have
received the copies of the supplemented or amended prospectus contemplated by Paragraph 3(h). 

        4.    Underwritten Offerings.    

        (a)    Underwriting Agreement.    If the Company at any time proposes to register any of its securities under the Act
as contemplated by Paragraph 1 or 2 and such securities are to be distributed by or through one or more underwriters, the Company will, subject to the provisions of Paragraph 1(b) or
2(c), use its best efforts to arrange for such underwriters to include the Registrable Securities to be offered and sold by a holder who elects to exercise his rights pursuant to Paragraph 1(a)
or 2(a) or (b) among the securities to be distributed by such underwriters for and on the same price, terms, and conditions offered to the Company, and each holder of Registrable Securities
agrees, by acquisition of such Registrable Securities, that all Registrable Securities of such holder to be included in such registration shall be distributed and sold through such underwriters. The
holders of Registrable Securities to be distributed by such underwriters shall be parties to the underwriting agreement between the Company and such underwriters and may, at their option, require that
any or all of the representations and warranties by, and the other agreements on the part of, the Company to and for the benefit of such underwriters shall also be made to and for the benefit of such
holders of Registrable Securities and that any or all of the conditions precedent to the obligations of such underwriters shall also be made to and for the benefit of such holders of Registrable
Securities. The Company will use its best efforts to ensure that no underwriter shall require any holder of Registrable Securities to make any representations or warranties to or agreements, including
indemnification obligations, with the Company or the underwriters other than representations, warranties or agreements, including indemnification obligations, regarding such holder and such holder's
intended method of distribution and any other representation required by law, and, despite the Company's best efforts, if an underwriter requires any holder of Registrable Securities to make
additional representation or warranties to or agreements, including indemnification obligations, with such underwriter, such holder may elect not to participate in such underwritten offering (but
shall not have any claims against the Company as a result of such election) and such election not to participate will not count as a Demand Registration. 

        (b)    Selection of Underwriters.    The selection of the underwriter or underwriters for the public offering to be
made pursuant to a registration statement filed under Paragraph 1 above shall be made by the Company, in its sole discretion, from amongst underwriting firms of national reputation.
Notwithstanding anything else in this Exhibit C to the contrary, if General Electric Pension Trust ("GEPT") is eligible to participate in an
underwriting pursuant to the terms hereof and the General Electric Company is directly or indirectly the beneficial owner of five percent (5%) or more of the outstanding equity interests of an
underwriter or underwriters acting in such underwriting, GEPT shall have the absolute right to disapprove such underwriter or underwriters so owned by General Electric Company. 

        (c)    Holdback Agreements.    

        (i)    Whether
or not a holder of Registrable Securities participates in a registration pursuant to Paragraph 1, such holder agrees by acquisition of its Registrable
Securities, if so requested by the Company or required by the managing underwriter, not to effect any public sale or distribution of such securities or sales of such securities pursuant to
Rule 144 under the Act or otherwise, (I) during the later to occur of (A) thirty (30) days prior to any firm commitment underwritten registration pursuant to
Paragraph 1 has become effective or (B) such period of time after which a written notice has been provided by the Company to such holder of an intention to undertake a firm commitment
underwritten registration 

C-6

 

pursuant
to Paragraph 1, and (II) the ninety (90) days after any firm commitment underwritten registration pursuant to Paragraph 1 has become effective;  provided, however, that either the Company or such managing underwriter shall be entitled, in its
discretion, to extend the period during which the sale or distribution of Registrable Securities is restricted pursuant to this paragraph by up to an additional one hundred and twenty
(120) days following the effective date of any such registration; provided, further, that this paragraph (i) shall not apply (x) to
any holder unless all executive officers and directors and greater than five percent (5%) stockholders of the Company enter into similar agreements or (y) for a period in excess of
120 days in the aggregate without first obtaining the consent of each holder affected thereby. 

        (ii)   The
Company agrees: 

        (A)  not
to effect any public sale or distribution of its equity securities or securities convertible into or exchangeable or exercisable for any of such securities during
the seven (7) days prior to and the ninety (90) days after any firm commitment underwritten registration pursuant to Paragraph 1 or 2 has become effective, except as part of such
underwritten registration and except pursuant to registrations on Form S-4 or Form S-8 or any successor or similar forms thereto, and 

        (B)  to
use its best efforts to cause each holder of its equity securities or any securities convertible into or exchangeable or exercisable for any of such securities, in
each case purchased from the Company at any time after the date hereof (other than in a public offering) to agree not to effect any such public sale or distribution of such securities, during such
period or, in either case, if the managing underwriter advises the Company in writing that in its opinion, no such public sale or distribution should be effected for a specified period longer than
ninety (90) days after such underwritten registration in order to complete the sale and distribution of securities included in such registration, during a reasonably longer period after such
underwritten registration, except as part of such underwritten registration. 

        5.    Preparation; Reasonable Investigation.    In connection with the preparation and filing of each registration
statement under the Act, the Company will give the holders of Registrable Securities registered under such registration statement, their underwriters, if any, and their respective counsel and
accountants, the opportunity to participate in the preparation of such registration statement, each prospectus included therein or filed with the Commission, and each amendment thereof or supplement
thereto, and will give each of them such access to its books and records and such opportunities to discuss the business,
finances and accounts of the Company and its subsidiaries with its officers, directors and the independent public accountants who have certified its financial statements as shall be necessary, in the
opinion of such holders' and such underwriters' respective counsel, to conduct a reasonable investigation within the meaning of the Act. 

        6.    Certain Rights of Holders.    The Company will not file any registration statement under the Act which refers to
any holder of Registrable Securities by name or otherwise without the prior written approval of such holder, which may not be unreasonably withheld. 

        7.    Indemnification.    

        (a)    Indemnification by the Company.    In the event of any registration of any securities of the Company under the
Act, the Company will, and hereby does, indemnify and hold harmless the seller of any Registrable Securities covered by any registration statement filed pursuant to Paragraph 1 or 2, its
directors, officers, partners, employees, agents and investment advisors, each other Person who participates as an underwriter in the offering or sale of such securities and each other Person, if any,
who controls such seller or any such underwriter within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act, from and against any losses, claims, 

C-7

 

damages
or liabilities, joint or several (or actions or proceedings, whether commenced or threatened, in respect thereof) (collectively, "Claims"), to
which such seller or any such director or officer or employee or agent or investment advisor or underwriter or controlling person may become subject under either Section 15 of the Act or
Section 20 of the Exchange Act or otherwise, insofar as such Claims arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any
registration statement under which such securities were registered under the Act, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or supplement
thereto (if used during the period the Company is required to keep the registration statement current) (collectively, "Registration Documents"), or any
omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances in which made, or
any violation by the Company of the Act or any state securities law, or any rule or regulation promulgated under the Act or any state securities law, or any other law applicable to the Company
relating to any such registration or qualification, and the Company will reimburse such seller and each such director, officer, employee, agent, investment advisor, underwriter and controlling person
for any legal or any other expenses reasonably incurred by them in connection with investigating or defending any such Claim; provided,  however, that the
Company shall not be liable in any such case to the extent that any such Claim or expense arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission made in any such Registration Document in reliance upon and in conformity with written information furnished to the Company
through an instrument duly executed by such seller stating that it is for use in the preparation thereof; provided, further, that the Company shall not
be liable to any Person who participates as an underwriter in the offering or sale of Registrable Securities or any other Person, if any, who controls such underwriter within the meaning of either
Section 15 of the Act or Section 20 of the Exchange Act (or the selling holder of Registrable Securities, if the sale is not made through an underwriter) in any such case to the extent
that any such Claim or expense arises out of such Person's failure to send or give a copy of the final prospectus to the Person claiming an untrue statement or alleged untrue statement or omission or
alleged omission at or prior to the written confirmation of the sale of Registrable Securities to such Person if such statement or omission was corrected in such final prospectus. Such indemnity shall
remain in full force and effect regardless of any investigation made by or on behalf of such seller or any such director, officer, employee, agent, investment advisor, partner, underwriter or
controlling person and shall survive the transfer of such securities by such seller. 

        (b)    Indemnification by the Sellers.    The Company may require, as a condition to including any Registrable
Securities in any registration statement filed pursuant to Paragraph 1 or 2, that the Company shall have received an undertaking satisfactory to it from the prospective seller of such
securities, to indemnify and hold harmless (in the same manner and to the same extent as set forth in this Paragraph 7(b)) the Company, each director of the Company, each officer of the Company
and each other person, if any, who controls the Company within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act and each underwriter participating in any
distribution being made pursuant to such registration statement, with respect to any statement or alleged statement or omission or alleged omission from such Registration Document, if such statement
or alleged statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company through an instrument duly executed by such seller
specifically stating that it is for use in the preparation of such Registration Document. Notwithstanding the foregoing, in no event shall any selling stockholder or any director, officer, employee,
agent, investment advisor or controlling person thereof be liable to indemnify the Company pursuant to this Paragraph 7(b) in an amount in excess of the amount of the net proceeds of the
Registrable Securities sold by him, her or it in any such offering. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the 

C-8

 

Company
of any such director, officer or controlling person and shall survive the transfer of such securities by such seller. The Company shall use its best efforts to ensure that no underwriter shall
require any holder of Registrable Securities to provide any indemnification other than that provided hereinabove in this Paragraph 7(b), and, if, despite the Company's best efforts, an
underwriter requires any holder of Registrable Securities to provide additional indemnification, such holder may elect not to participate in such underwritten offering (but shall not have any claim
against the Company as a result of such election) and such election not to participate will not count as a Demand Registration. 

        (c)    Notices of Claims, etc.    Promptly after receipt by an indemnified party of notice of the commencement of any
action or proceeding involving a Claim referred to in the preceding subdivisions of this Paragraph 7, such indemnified party will, if a claim in respect thereof is to be made against an
indemnifying party, give written notice to the latter of the commencement of such action; provided,  however, that the failure of any indemnified party to
give notice as provided herein shall not relieve the indemnifying party of its obligations under
the preceding subdivisions of this Paragraph 7, except to the extent that the indemnifying party is actually prejudiced by such failure to give notice. In case any such action is brought
against an indemnified party, unless in such indemnified party's reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist in respect of such claim, the
indemnifying party shall be entitled to participate in and to assume the defense thereof, jointly with any other indemnifying party similarly notified to the extent that it may wish, with counsel
reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall
not be liable to such indemnified party for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof other than reasonable costs of investigation. No
indemnifying party shall consent to entry of any judgment or enter into any settlement of any pending or threatened proceeding in respect of which an indemnified party is or could have been a party
and indemnity could have been sought under Paragraph 7(a) without the consent of the indemnified party which does not include as an unconditional term thereof the giving by the claimant or
plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation. 

        (d)    Other Indemnification.    Indemnification similar to that specified in the preceding subdivisions of this
Paragraph 7 (with appropriate modifications) shall be given by the Company and each seller of Registrable Securities with respect to any required registration or other qualification of
securities under any Federal or state law or regulation of any governmental authority, other than the Act. If the indemnification provided for in Paragraphs 7(a), (b) or (c) is
unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party, in lieu of indemnifying such indemnified
party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to
reflect the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party or parties on the other hand from the offering of the securities or (ii) if
the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as
well as any other relevant equitable considerations; provided, however, that in no event shall any
contribution by the selling stockholder or any director, officer, employee, agent, investment advisor or controlling person thereof pursuant to this Paragraph 7(d) exceed the amount of the net
proceeds of the Registrable Securities sold by him, her or it in any such offering. 

C-9

 

        (e)    Indemnification Payments.    The indemnification required by this Paragraph 7 shall be made by periodic
payments of the amount thereof during the course of the investigation or defense, as and when bills are received or expense, loss, damage or liability is incurred. 

        8.    Adjustment Affecting Registrable Securities.    The Company will not effect or permit to occur any combination
or subdivision of shares which would adversely affect the ability of the holders of Registrable Securities to effect the registration of such securities in the manner contemplated by these
registration rights provisions. 

        9.    Covenants Relating to Rule 144.    At all times after the effective date of the registration statement
under the Act of the initial underwritten public offering of Common Stock, and until such time as all of the Registrable Securities cease to be Registrable Securities, the Company will file reports in
compliance with the Exchange Act and will, at its expense, forthwith upon the request of any holder of Restricted Securities (as defined in Rule 144 (or any successor provision under the Act)),
deliver to such holder a certificate, signed by the Company's principal financial officer, stating: 

        (a)   the
Company's name, address and telephone number (including area code); 

        (b)   the
Company's Internal Revenue Service identification number; 

        (c)   the
Company's Commission file number; 

        (d)   the
number of shares of Common Stock of the Company outstanding as shown by the most recent report or statement published by the Company; and 

        (e)   whether
the Company has filed the reports required to be filed under the Exchange Act for a period of at least ninety (90) days prior to the date of such
certificate and in addition has filed the most recent annual report required to be filed thereunder.
