principal thereof from the date of issuance at their stated rate of interest payable semi-annually in arrears on the last day of March and September in each year and at maturity commencing on September 30, 2008, until such principal sum shall

the continuance of an Event of Default, on the unpaid balance hereof, at the Default Rate until paid.

 Section 5.1. Organization; Power and Authority. The Company is a corporation duly organized, validly existing and in good standing under the laws of its jurisdiction of incorporation, and is duly qualified
as a foreign corporation and is in good standing in each jurisdiction in which such qualification is required by law, other than those jurisdictions as to which the failure to be so qualified or in good standing could not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect. The Company has the corporate power and authority to own or hold under lease the properties it purports to own or hold under lease, to transact the business it transacts and
proposes to transact, to execute and deliver this Agreement and the Notes and to perform the provisions hereof and thereof. 
 Section 5.2. Authorization, Etc. This Agreement and the Notes have been duly authorized by all necessary corporate action on the part of the Company, and this Agreement constitutes, and upon execution and delivery thereof each
Note will constitute, a legal, valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except as such enforceability may be limited by (i) applicable bankruptcy, insolvency, reorganization,
moratorium or other similar laws affecting the enforcement of creditors’ rights generally and (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law). 
 Section 5.3. Disclosure. The documents filed by the Company with the Securities and Exchange Commission (the “Public
Filings”) fairly describe, in all material respects, the general nature of the business and principal properties of the Company and its Subsidiaries. This Agreement, the Public Filings, the documents, certificates or other writings
delivered to the Purchasers by or on behalf of the Company in connection with the transactions contemplated hereby and the financial statements referred to in Section 5.5, in each case, delivered (or deemed to be delivered by reference to the
Public Filings) to the Purchasers prior to March 14, 2008 being referred to, collectively, as the “Disclosure Documents”), taken as a whole, do not contain any untrue statement of a material fact or omit to state any material

foreign corporation or other legal entity and is in good standing in each jurisdiction in which such qualification is required by law, other than those jurisdictions as to which the failure to be so qualified or in good standing could not,
individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. Each such Subsidiary has the corporate or other power and authority to own or hold under lease the properties it purports to own or hold under lease and to
transact the business it transacts and proposes to transact. 
 (d) No Subsidiary is a party to, or otherwise subject to any legal,
regulatory, contractual or other restriction (other than this Agreement, the agreements listed on Schedule 5.4 and customary limitations imposed by corporate law or similar statutes) restricting the ability of such Subsidiary to pay dividends out of
profits or make any other similar distributions of profits to the Company or any of its Subsidiaries that owns outstanding shares of capital stock or similar equity interests of such Subsidiary.

the periods involved except as set forth in the notes thereto (subject, in the case of any interim financial statements, to normal 

  

 -6- 

 
year-end adjustments). The Company and its Subsidiaries do not have any Material liabilities that are not disclosed on such financial statements or otherwise
disclosed in the Disclosure Documents. 
 Section 5.6. Compliance with Laws, Other Instruments, Etc. The execution, delivery and
performance by the Company of this Agreement and the Notes will not (i) contravene, result in any breach of, or constitute a default under, or result in the creation of any Lien in respect of any property of the Company or any Subsidiary under,
any indenture, mortgage, deed of trust, loan, purchase or credit agreement, lease, corporate charter or by-laws, or any other agreement or instrument to which the Company or any Subsidiary is bound or by which the Company or any Subsidiary or any of
their respective properties may be bound or affected, (ii) conflict with or result in a breach of any of the terms, conditions or provisions of any order, judgment, decree, or ruling of any court, arbitrator or Governmental Authority applicable
to the Company or any Subsidiary or (iii) violate any provision of any statute or other rule or regulation of any Governmental Authority applicable to the Company or any Subsidiary.

party or by which it is bound, or any order, judgment, decree or ruling of any court, arbitrator or Governmental Authority or is in violation of any applicable law, ordinance, rule or regulation (including without limitation Environmental Laws or
the USA Patriot Act) of any Governmental Authority, which default or violation, individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect. 
 Section 5.9. Taxes. The Company and its Subsidiaries have filed all tax returns that are required to have been filed in any jurisdiction, and
have paid all taxes shown to be due and payable on such returns and all other taxes and assessments levied upon them or their properties, assets, income or franchises, to the extent such taxes and assessments have become due and payable and before
they have become delinquent, except for any taxes and assessments (i) the amount of which is not individually or in the aggregate Material or (ii) the amount, applicability or validity of which is currently being contested in good faith by
appropriate proceedings and with respect to which the Company or a Subsidiary, as the case may be, has established adequate reserves in accordance with GAAP. The Company knows of no basis for any other tax or assessment that could reasonably be
expected to have a Material Adverse Effect. The charges, accruals and reserves on the books of the Company and its Subsidiaries in respect of Federal, 

  

 -7- 

 
state or other taxes for all fiscal periods are adequate. The Federal income tax liabilities of the Company and its Subsidiaries have been finally determined

 (c) To the best knowledge of the Company, there is no Material violation by any Person of any right of the Company or any of its Subsidiaries with respect to any patent, copyright, proprietary software, service mark, trademark, trade name

 Section 5.12. Compliance with ERISA. (a) The
Company and each ERISA Affiliate have operated and administered each Plan in compliance with all applicable laws except for such instances of noncompliance as have not resulted in and could not reasonably be expected to result in a Material Adverse
Effect. Neither the Company nor any ERISA Affiliate has incurred any liability pursuant to Title I or IV of ERISA or the penalty or excise tax provisions of the Code relating to employee benefit plans (as defined in section 3 of ERISA),
and no event, transaction or condition has occurred or exists that could reasonably be expected to result in the incurrence of any such liability by the Company or any ERISA Affiliate, or in the imposition of any Lien on any of the rights,
properties or assets of the Company or any ERISA Affiliate, in either case pursuant to Title I or IV of ERISA or to such penalty or excise tax provisions or to section 401(a)(29) or 412 of the Code or section 4068 of ERISA, other than such

under each of the Plans (other than Multiemployer Plans), determined as of the end of such Plan’s most recently ended plan year on the basis of the actuarial assumptions specified for funding purposes in such Plan’s most recent actuarial

“current value” and “present value” have the meaning specified in section 3 of ERISA. 
  

 -8-

contingent withdrawal liabilities) under section 4201 or 4204 of ERISA in respect of Multiemployer Plans that individually or in the aggregate are Material. 
 (d) The expected postretirement benefit obligation (determined as of the last day of the Company’s most recently ended fiscal year in accordance with Financial Accounting Standards Board Statement No. 106,
without regard to liabilities attributable to continuation coverage mandated by section 4980B of the Code) of the Company and its Subsidiaries is not Material. 
 (e) The execution and delivery of this Agreement and the issuance and sale of the Notes hereunder will not involve any transaction that is subject to the prohibitions of section 406 of ERISA or in connection with
which a tax could be imposed pursuant to section 4975(c)(1)(A)-(D) of the Code. The representation by the Company to each Purchaser in the first sentence of this Section 5.12(e) is made in reliance upon and subject to the accuracy of
such Purchaser’s representation in Section 6.2 as to the sources of the funds used to pay the purchase price of the Notes to be purchased by such Purchaser.

Company nor anyone acting on its behalf has taken, or will take, any action that would subject the issuance or sale of the Notes to the registration requirements of Section 5 of the Securities Act or to the registration requirements of any
securities or blue sky laws of any applicable jurisdiction. 
 Section 5.14. Use of Proceeds; Margin Regulations. The Company
will apply the proceeds of the sale of the Notes to finance an acquisition and for general corporate purposes. No part of the proceeds from the sale of the Notes hereunder will be used, directly or indirectly, for the purpose of buying or carrying
any margin stock within the meaning of Regulation U of the Board of Governors of the Federal Reserve System (12 CFR 221), or for the purpose of buying or carrying or trading in any securities under such circumstances as to involve the Company
in a violation of Regulation X of said Board (12 CFR 224) or to involve any broker or dealer in a violation of Regulation T of said Board (12 CFR 220). Margin stock does not constitute more than 5% of the value of the consolidated assets of the
Company and its Subsidiaries and the Company does not have any present intention that margin stock will constitute more than 5% of the value of such assets. As used in this Section, the terms “margin stock” and
“purpose of buying or carrying” shall have the meanings assigned to them in said Regulation U. 
 Section 5.15.

and obligees, principal amount outstanding and collateral therefor, if any, and Guarantee thereof, if any), since which date there has been no Material
change in the amounts, interest rates, sinking funds, installment payments or maturities of the Indebtedness of the Company or its Subsidiaries. Neither the Company nor any Subsidiary is in default and no waiver of default is currently in effect, in
the payment of any principal or interest on any Indebtedness of the Company or such Subsidiary and no event or condition exists with respect to any Indebtedness of the Company or any Subsidiary that would permit (or that with notice or the lapse of
time, or both, would permit) one or more Persons to cause such Indebtedness to become due and payable before its stated maturity or before its regularly scheduled dates of payment. 
 (b) Except as disclosed in Schedule 5.15, neither the Company nor any Subsidiary has agreed or consented to cause or permit in the future (upon the
happening of a contingency or otherwise) any of its property, whether now owned or hereafter acquired, to be subject to a Lien not permitted by Section 10.5. 
 (c) Neither the Company nor any Subsidiary is a party to, or otherwise subject to any provision contained in, any instrument evidencing Indebtedness of the Company or such Subsidiary, any agreement relating thereto or
any other agreement (including, but not limited to, its charter or other organizational document) which limits the amount of, or otherwise imposes restrictions on the incurring of, Indebtedness of the Company, except as specifically indicated in
Schedule 5.15. 
 Section 5.16. Foreign Assets Control Regulations, Etc. (a) Neither the sale of the Notes by the
Company hereunder nor its use of the proceeds thereof will violate the Trading with the Enemy Act, as amended, or any of the foreign assets control regulations of the United States Treasury Department (31 CFR, Subtitle B, Chapter V, as
amended) or any enabling legislation or executive order relating thereto.

operated by any of them or other assets, alleging any damage to the environment or violation of any Environmental Laws, except, in each case, such as could not reasonably be expected to result in a Material Adverse Effect. 
 (b) Neither the Company nor any Subsidiary has knowledge of any facts which would give rise to any claim, public or private, of violation of
Environmental Laws or damage to the environment emanating from, occurring on or in any way related to real properties now or formerly owned, leased or operated by any of them or to other assets or their use, except, in each case, such as could not
reasonably be expected to result in a Material Adverse Effect.

contingent) of the Company, including, without limitation, all senior unsecured Indebtedness of the Company described in Schedule 5.15 hereto.

Subsidiaries with the Company’s officers, and (with the consent of the Company, which consent will not be unreasonably withheld) its independent public accountants, and (with the consent of the Company, which consent will not be unreasonably

requested. 
  

	SECTION 8.	PAYMENT OF THE NOTES. 

 Section 8.1. Required Prepayments. (a) On March 31, 2012 and on each March 31 thereafter to and including March 31, 2017, the Company will prepay $14,285,714 principal amount (or such
lesser principal amount as shall then be outstanding) of the Notes at par and without payment of the Make-Whole Amount or any premium. The entire unpaid principal amount of the Notes shall become due and payable on March 31, 2018. 

(b) Upon any partial prepayment of the Notes pursuant to Section 8.2 or Section 8.7, the principal amount of each required prepayment of the
Notes becoming due under this Section 8.1 on and after the date of such prepayment or purchase shall be reduced in the same proportion as the aggregate unpaid principal amount of the Notes is reduced as a result of such prepayment or purchase.

  

 -17- 

 Section 8.2. Optional Prepayments with Make-Whole Amount. The Company may, at its option,
upon notice as provided below, prepay at any time all, or from time to time any part of, the Notes, in an amount not less than 10% of the aggregate principal amount of the Notes then outstanding in the case of a partial prepayment (or such lesser
amount as shall be required to effect a partial prepayment resulting from an offer of prepayment pursuant to Section 10.6), at 100% of the principal amount so prepaid, together with interest accrued thereon to the date of such prepayment, plus
the Make-Whole Amount determined for the prepayment date with respect to such principal amount. The Company will give each holder of Notes written notice of each optional prepayment under this Section 8.2 not less than 30 days and not more than
60 days prior to the date fixed for such prepayment. Each such notice shall specify such date (which shall be a Business Day), the aggregate principal amount of the Notes to be prepaid on such date, the principal amount of each Note held by such
holder to be prepaid (determined in accordance with Section 8.3), and the interest to be paid on the prepayment date with respect to such principal amount being prepaid, and shall be accompanied by a certificate of a Senior Financial Officer as
to the estimated Make-Whole Amount due in connection with such prepayment (calculated as if the date of such notice were the date of the prepayment), setting forth the details of such computation. Two Business Days prior to such prepayment, the
Company shall deliver to each holder of Notes a certificate of a Senior Financial Officer specifying the calculation of such Make-Whole Amount as of the specified prepayment date. 
 Section 8.3. Allocation of Partial Prepayments. In the case of each partial prepayment of the Notes, the principal amount of the Notes to be
prepaid shall be allocated among all of the Notes at the time outstanding in proportion, as nearly as practicable, to the respective unpaid principal amounts thereof not theretofore called for prepayment. 
 Section 8.4. Maturity; Surrender, Etc. In the case of each prepayment of Notes pursuant to this Section 8, the principal amount of each
Note to be prepaid shall mature and become due and payable on the date fixed for such prepayment (which shall be a Business Day), together with interest on such principal amount accrued to such date and the applicable Make-Whole Amount. From and
after such date, unless the Company shall fail to pay such principal amount when so due and payable, together with the interest and Make-Whole Amount as aforesaid, interest on such principal amount shall cease to accrue. Any Note paid or prepaid in
full shall be surrendered to the Company and cancelled and shall not be reissued, and no Note shall be issued in lieu of any prepaid principal amount of any Note. 
 Section 8.5. Purchase of Notes. The Company will not and will not permit any Affiliate to purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of the outstanding Notes except upon the
payment or prepayment of the Notes in accordance with the terms of this Agreement and the Notes. The Company will promptly cancel all Notes acquired by it or any Affiliate pursuant to any payment or prepayment of Notes pursuant to any provision of
this Agreement and no Notes may be issued in substitution or exchange for any such Notes. 
 Section 8.6. Make-Whole Amount for the
Notes. The term “Make-Whole Amount” means with respect to any Note an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such Note,
minus the amount of such Called Principal, provided that the Make-Whole Amount may in no event be less than zero. For the purposes of determining the Make-Whole Amount, the following terms have the following meanings with respect to
the Called Principal of such Note: 
  

 -18- 

 “Called Principal” means, the principal of any Note that is to be
prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires. 
 “Discounted Value” means, the amount obtained by discounting all Remaining Scheduled Payments from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in
accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on such Note is payable) equal to the Reinvestment Yield. 
 “Reinvestment Yield” means, 0.50% plus the yield to maturity calculated by using (i) the yields reported, as of
10:00 A.M. (New York City time) on the second Business Day preceding the Settlement Date on screen “PX-1” on the Bloomberg Financial Market Service (or such other information service as may replace Bloomberg) for actively traded
U.S. Treasury securities having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date, or (ii) if such yields are not reported as of such time or the yields reported as of such time are not
ascertainable, the Treasury Constant Maturity Series Yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date, in Federal Reserve Statistical Release H.15 (519)
(or any comparable successor publication) for actively traded U.S. Treasury securities having a constant maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. In either case, the yield will be determined,
if necessary, by (a) converting U.S. Treasury bill quotations to bond-equivalent yields in accordance with accepted financial practice and (b) interpolating linearly on a straight line basis between (1) the actively traded U.S.
Treasury security with the maturity closest to and greater than the Remaining Average Life and (2) the actively traded U.S. Treasury security with the maturity closest to and less than the Remaining Average Life. 
 “Remaining Average Life” means, the number of years (calculated to the nearest one-twelfth year) obtained by dividing
(i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment by (b) the number of years (calculated to the nearest one-twelfth year) that will
elapse between the Settlement Date and the scheduled due date of such Remaining Scheduled Payment. 
 “Remaining
Scheduled Payments” means, all payments of such Called Principal and interest thereon that would be due after the Settlement Date if no payment of such Called Principal were made prior to its scheduled due date, provided that if such
Settlement Date is not a date on which interest payments are due to be made under the terms of such Note, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and
required to be paid on such Settlement Date pursuant to Section 8.2 or 12.1. 
  

 -19- 

 “Settlement Date” means, the date on which such Called Principal is to
be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires. 
 Section 8.7. Change in Control. (a) Notice of Change in Control or Control Event. The Company will, within 15 Business Days after any Responsible Officer has knowledge of the occurrence of
any Change in Control or Control Event, give written notice of such Change in Control or Control Event to each holder of Notes unless notice in respect of such Change in Control (or the Change in Control contemplated by such Control Event)
shall have been given pursuant to subparagraph (b) of this Section 8.7. If a Change in Control has occurred, such notice shall contain and constitute an offer to prepay Notes as described in subparagraph (c) of this Section 8.7
and shall be accompanied by the certificate described in subparagraph (g) of this Section 8.7. 
 (b) Condition to Company
Action. The Company will not take any action that consummates or finalizes a Change in Control unless (i) at least 15 Business Days prior to such action it shall have given to each holder of Notes written notice containing and
constituting an offer to prepay Notes as described in subparagraph (c) of this Section 8.7, accompanied by the certificate described in subparagraph (g) of this Section 8.7, and (ii) contemporaneously with such action, it
prepays all Notes required to be prepaid in accordance with this Section 8.7. 
 (c) Offer to Prepay Notes. The offer to prepay
Notes contemplated by subparagraphs (a) and (b) of this Section 8.7 shall be an offer to prepay, in accordance with and subject to this Section 8.7, all, but not less than all, the Notes held by each holder (in this case only,
“holder” in respect of any Note registered in the name of a nominee for a disclosed beneficial owner shall mean such beneficial owner) on a date specified in such offer (the “Proposed Prepayment Date”). If such
Proposed Prepayment Date is in connection with an offer contemplated by subparagraph (a) of this Section 8.7, such date shall be not less than 20 days and not more than 30 days after the date of such offer (if the Proposed
Prepayment Date shall not be specified in such offer, the Proposed Prepayment Date shall be the 20th day after the date of such offer). 
 (d) Acceptance; Rejection. A holder of Notes may accept the offer to prepay made pursuant to this Section 8.7 by causing a notice of such acceptance or rejection to be delivered to the Company at least 5 Business Days prior to
the Proposed Prepayment Date. A failure by a holder of Notes to respond to an offer to prepay made pursuant to this Section 8.7 shall be deemed to constitute a rejection of such offer by such holder. 
 (e) Prepayment. Prepayment of the Notes to be prepaid pursuant to this Section 8.7 shall be at 100% of the principal amount of such Notes,
together with interest on such Notes accrued to the date of prepayment. The prepayment shall be made on the Proposed Prepayment Date except as provided in subparagraph (f) of this Section 8.7. 
 (f) Deferral Pending Change in Control. The obligation of the Company to prepay Notes pursuant to the offers required by subparagraph (b) and
accepted in accordance with subparagraph (d) of this Section 8.7 is subject to the occurrence of the Change in Control in respect of which such offers and acceptances shall have been made. In the event that such 

  

 -20- 

 
Change in Control does not occur on the Proposed Prepayment Date in respect thereof, the prepayment shall be deferred until and shall be made on the date on
which such Change in Control occurs. The Company shall keep each holder of Notes reasonably and timely informed of (i) any such deferral of the date of prepayment, (ii) the date on which such Change in Control and the prepayment are
expected to occur, and (iii) any determination by the Company that efforts to effect such Change in Control have ceased or been abandoned (in which case the offers and acceptances made pursuant to this Section 8.7 in respect of such Change
in Control shall be deemed rescinded). 
 (g) Officer’s Certificate. Each offer to prepay the Notes pursuant to this
Section 8.7 shall be accompanied by a certificate, executed by a Senior Financial Officer of the Company and dated the date of such offer, specifying: (i) the Proposed Prepayment Date; (ii) that such offer is made pursuant to this
Section 8.7; (iii) the principal amount of each Note offered to be prepaid; (iv) the interest that would be due on each Note offered to be prepaid, accrued to the Proposed Prepayment Date; (v) that the conditions of this
Section 8.7 have been fulfilled; and (vi) in reasonable detail, the nature and date or proposed date of the Change in Control. 
 (h) Effect on Required Payments. The amount of each payment of the principal of the Notes made pursuant to this Section 8.7 shall be applied against and reduce each of the then remaining principal payments due pursuant to
Section 8.7 by a percentage equal to the aggregate principal amount of the Notes so paid divided by the aggregate principal amount of the Notes outstanding immediately prior to such payment. 
 (i) “Change in Control” Defined. “Change in Control” means, with respect to any Person, an event or series of events by
which: 
 (a) any “person” or “group” (as such terms are used in Sections 13(d) and 14(d) of the Exchange
Act, but excluding any employee benefit plan of such person or its subsidiaries, and any person or entity acting in its capacity as trustee, agent or other fiduciary or administrator of any such plan) becomes the “beneficial owner” (as
defined in Rules 13d-3 and 13d-5 under the Securities Exchange, except that a person or group shall be deemed to have “beneficial ownership” of all securities that such person or group has the right to acquire (such right, an
“option right”), whether such right is exercisable immediately or only after the passage of time), directly or indirectly, of 35% or more of the equity securities of such Person entitled to vote for members of the board of directors
or equivalent governing body of such Person on a fully-diluted basis (and taking into account all such securities that such person or group has the right to acquire pursuant to any option right); or 
 (b) during any period of 12 consecutive months, a majority of the members of the board of directors or other equivalent governing body of
such Person cease to be composed of individuals (i) who were members of that board or equivalent governing body on the first day of such period, (ii) whose election or nomination to that board or equivalent governing body was approved by
individuals referred to in clause (i) above constituting at the time of such election or nomination at least a majority of that board or equivalent governing body or (iii) whose election or nomination to that board or other 

  

 -21- 

 
equivalent governing body was approved by individuals referred to in clauses (i) and (ii) above constituting at the time of such election or
nomination at least a majority of that board or equivalent governing body (excluding, in the case of both clause (ii) and clause (iii), any individual whose initial nomination for, or assumption of office as, a member of that board or
equivalent governing body occurs as a result of an actual or threatened solicitation of proxies or consents for the election or removal of one or more directors by any person or group other than a solicitation for the election of one or more
directors by or on behalf of the board of directors). 
 (j) “Control Event” Defined. “Control Event”
means: 
 (i) the execution by the Company or any of its Subsidiaries or Affiliates of any agreement or letter of intent with
respect to any proposed transaction or event or series of transactions or events which, individually or in the aggregate, may reasonably be expected to result in a Change in Control, 
 (ii) the execution of any written agreement which, when fully performed by the parties thereto, would result in a Change in Control, or

 (iii) the making of any written offer by any person (as such term is used in section 13(d) and section 14(d)(2) of the
Exchange Act as in effect on the date of the Closing) or related persons constituting a group (as such term is used in Rule 13d-5 under the Exchange Act as in effect on the date of the Closing) to the holders of the common stock of the Company,
which offer, if accepted by the requisite number of holders, would result in a Change in Control.

 Section 9.1. Compliance with Law. Without
limiting Section 10.10, the Company will, and will cause each of its Subsidiaries to, comply with all laws, ordinances or governmental rules or regulations to which each of them is subject, including, without limitation, ERISA, the USA Patriot

businesses, in each case to the extent necessary to ensure that non-compliance with such laws, ordinances or governmental rules or regulations or failures to obtain or maintain in effect such licenses, certificates, permits, franchises and other
governmental authorizations could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. 
 Section 9.2. Insurance. The Company will, and will cause each of its Subsidiaries to, maintain, with financially sound and reputable insurers, insurance with respect to their respective properties and businesses against such

shown to be due and payable on such returns and all other taxes, assessments, governmental charges, or levies imposed on them or any of their properties, assets, income or franchises, to the extent the same have become due and payable and before
they have become delinquent and all claims for which sums have become due and payable that have or might become a Lien on properties or assets of the Company or any Subsidiary, provided that neither the Company nor any Subsidiary need pay any
such tax, assessment, charge, levy or claim if (i) the amount, applicability or validity thereof is contested by the Company or such Subsidiary on a timely basis in good faith and in appropriate proceedings, and the Company or a Subsidiary has
established adequate reserves therefor in accordance with GAAP on the books of the Company or such Subsidiary or (ii) the nonpayment of all such taxes, assessments, charges, levies and claims in the aggregate could not reasonably be expected to
have a Material Adverse Effect. 
 Section 9.5. Corporate Existence, Etc. Subject to Section 10.6, the Company will at all
times preserve and keep in full force and effect its corporate existence. Subject to Sections 10.6 and 10.7, the Company will at all times preserve and keep in full force and effect the corporate existence of each of its Subsidiaries (unless merged
into the Company or a Wholly-Owned Subsidiary) and all rights and franchises of the Company and its Subsidiaries unless, in the good faith judgment of the Company, the termination of or failure to preserve and keep in full force and effect such

the Bank Credit Agreement and all other present and future unsecured Indebtedness (actual or contingent) of the Company which is not expressed to be subordinate or junior in rank to any other unsecured Indebtedness of the Company.

 (a) a joinder agreement in respect of the Subsidiary
Guaranty;

in accordance with its terms, except as an enforcement of such terms may be limited by bankruptcy, insolvency, fraudulent conveyance and similar laws affecting the enforcement of creditors’ rights generally and by general equitable principles.

 Section 9.8. Books and Records. The Company will, and will cause each of its Subsidiaries to, maintain proper books of record
and account in conformity with GAAP and all applicable requirements of any Governmental Authority having legal or regulatory jurisdiction over the Company or such Subsidiary, as the case may be.

 Section 10.2. Consolidated Indebtedness to Consolidated EBITDA. The Company will not permit, at the end of any fiscal quarter, the ratio of Consolidated Indebtedness to Consolidated EBITDA (Consolidated

 Section 10.6. Sales of Assets. The Company will not, and will not permit any Subsidiary to,

substantial part of the assets of the Company and its Subsidiaries if such assets are sold in an arms length transaction and, at such time and after giving effect thereto, no Default or Event of Default shall have occurred and be continuing and an
amount equal to the net proceeds received from such sale, lease or other disposition (but only with respect to that portion of such assets that exceeds the definition of “substantial part” set forth below) shall be used within 365 days of
such sale, lease or disposition, in any combination: 
 (1) to acquire productive assets used or useful in carrying on the
business of the Company and its Subsidiaries and having a value at least equal to the value of such assets sold, leased or otherwise disposed of; and/or 
 (2) to prepay or retire Senior Indebtedness of the Company and/or its Subsidiaries, provided that (i) the Company shall offer to prepay each outstanding Note in a principal amount which equals the Ratable
Portion for such Note, and (ii) any such prepayment of the Notes shall be made at par, together with accrued interest thereon to the date of such prepayment, but without the payment of the Make-Whole Amount. Any offer of prepayment of the Notes
pursuant to this Section 10.6 shall be given to each holder of the Notes by written notice that shall be delivered not less than fifteen (15) days and not more than sixty (60) days prior to the proposed prepayment date. Each such
notice shall state that it is given pursuant to this Section and that the offer set forth in such notice must be accepted by such holder in writing and shall also set forth (i) the prepayment date, (ii) a description of the circumstances
which give rise to the proposed prepayment and (iii) a calculation of the Ratable Portion for such holder’s Notes. Each holder of the Notes which desires to have its Notes prepaid shall notify the Company in writing delivered not less than
five (5) Business Days prior to the proposed prepayment date of its acceptance of such offer of prepayment. Prepayment of Notes pursuant to this Section 10.6 shall be made in accordance with Section 8.2 (but without payment of the
Make-Whole Amount). 
 As used in this Section 10.6, a sale, lease or other disposition of assets shall be deemed to be a
“substantial part” of the assets of the Company and its Subsidiaries if the book value of such assets, when added to the book value of all other assets sold, leased or otherwise disposed of by the Company and its Subsidiaries during
the period of 12 consecutive months ending on the date of such sale, lease or other disposition, exceeds 10% of the book value of Consolidated Total Assets, determined as of the end of the fiscal quarter immediately preceding such sale, lease or

Section 11 (other than an Event of Default described in clause (i) of paragraph (h) or described in clause (vi) of paragraph (h) by virtue of the fact that such clause encompasses clause (i) of paragraph (h)) has
occurred, all the Notes then outstanding shall automatically become immediately due and payable. 
 (b) If any other Event of Default has
occurred and is continuing, any holder or holders of more than 50% in aggregate principal amount of the Notes at the time outstanding may at any time at its or their option, by notice or notices to the Company, declare all the Notes then outstanding
to be immediately due and payable. 
  

 -31- 

 (c) If any Event of Default described in paragraph (a) or (b) of Section 11 has occurred
and is continuing with respect to any Notes, any holder or holders of Notes at the time outstanding affected by such Event of Default may at any time, at its or their option, by notice or notices to the Company, declare all the Notes held by such
holder or holders to be immediately due and payable. 
 Upon any Note’s becoming due and payable under this Section 12.1, whether
automatically or by declaration, such Note will forthwith mature and the entire unpaid principal amount of such Note, plus (i) all accrued and unpaid interest thereon (including, but not limited to, interest accrued thereon at the Default Rate)
and (ii) the Make-Whole Amount determined in respect of such principal amount (to the full extent permitted by applicable law), shall all be immediately due and payable, in each and every case without presentment, demand, protest or further
notice, all of which are hereby waived. The Company acknowledges, and the parties hereto agree, that each holder of a Note has the right to maintain its investment in the Notes free from repayment by the Company (except as herein specifically
provided for) and that the provision for payment of a Make-Whole Amount by the Company in the event that the Notes are prepaid or are accelerated as a result of an Event of Default, is intended to provide compensation for the deprivation of such
right under such circumstances. 
 Section 12.2. Other Remedies. If any Default or Event of Default has occurred and is
continuing, and irrespective of whether any Notes have become or have been declared immediately due and payable under Section 12.1, the holder of any Note at the time outstanding may proceed to protect and enforce the rights of such holder by
an action at law, suit in equity or other appropriate proceeding, whether for the specific performance of any agreement contained herein or in any Note, or for an injunction against a violation of any of the terms hereof or thereof, or in aid of the
exercise of any power granted hereby or thereby or by law or otherwise. 
 Section 12.3. Rescission. At any time after the Notes
have been declared due and payable pursuant to clause (b) or (c) of Section 12.1, the holders of not less than 51% in aggregate principal amount of the Notes then outstanding, by written notice to the Company, may rescind and annul
any such declaration and its consequences if (a) the Company has paid all overdue interest on the Notes, all principal of and Make-Whole Amount on any Notes that are due and payable and are unpaid other than by reason of such declaration, and
all interest on such overdue principal and Make-Whole Amount and (to the extent permitted by applicable law) any overdue interest in respect of the Notes, at the Default Rate, (b) neither the Company nor any other Person shall have paid any
amounts which have become due solely by reason of such declaration, (c) all Events of Default and Defaults, other than non-payment of amounts that have become due solely by reason of such declaration, have been cured or have been waived
pursuant to Section 17, and (d) no judgment or decree has been entered for the payment of any monies due pursuant hereto or to any Notes. No rescission and annulment under this Section 12.3 will extend to or affect any subsequent
Event of Default or Default or impair any right consequent thereon. 
 Section 12.4. No Waivers or Election of Remedies, Expenses,
Etc. No course of dealing and no delay on the part of any holder of any Note in exercising any right, power or remedy shall operate as a waiver thereof or otherwise prejudice such holder’s rights, powers or remedies. No 

  

 -32- 

 
right, power or remedy conferred by this Agreement or by any Note upon any holder thereof shall be exclusive of any other right, power or remedy referred to
herein or therein or now or hereafter available at law, in equity, by statute or otherwise. Without limiting the obligations of the Company under Section 15, the Company will pay to the holder of each Note on demand such further amount as shall
be sufficient to cover all costs and expenses of such holder incurred in any enforcement or collection under this Section 12, including, without limitation, reasonable attorneys’ fees, expenses and disbursements.

Note or such holder’s attorney duly authorized in writing and accompanied by the relevant name, address and other information for notices of each transferee of such Note or part thereof), within ten Business Days thereafter, the Company shall
execute and deliver, at the Company’s expense (except as provided below), one or more new Notes (as requested by the holder thereof) in exchange therefor, in an aggregate principal amount equal to the unpaid principal amount of the surrendered
Note. Each such new Note shall be payable to such Person as such holder may request and shall be substantially in the form of the Note originally issued hereunder. Each such new Note shall be dated and bear interest from the date to which interest

of any such transfer of Notes. Notes shall not be transferred in denominations of less than $100,000, provided that if necessary to enable the registration of transfer by a holder of its entire holding of Notes, one Note may be in a
denomination of less than $100,000. Any transferee, by its acceptance of a Note registered in its name (or the name of its nominee), shall be deemed to have made the representation set forth in Section 6.2, provided, that in lieu thereof
such holder may (in reliance upon information provided by the Company, which shall not be unreasonably withheld) make a representation to the effect that the purchase by any holder of any Note will not constitute a non-exempt prohibited transaction
under section 406(a) of ERISA. 
 Section 13.3. Replacement of Notes. Upon receipt by the Company at the address and to the
attention of the designated officer (all as specified in Section 18(iv)) of evidence reasonably

of at least $100,000,000 or a Qualified Institutional Buyer, such Person’s own unsecured agreement of indemnity shall be deemed to be satisfactory), or 
 (b) in the case of mutilation, upon surrender and cancellation thereof, 
 the Company at its own expense shall execute and deliver not more than five Business Days following satisfaction of such conditions, in lieu thereof, a new Note, dated and bearing interest from the date to which

after payment or prepayment in full of any Note or such Purchaser shall surrender such Note for cancellation, reasonably promptly after any such request, to the Company at its principal executive office or at the place of payment most recently
designated by the Company pursuant to Section 14.1. Prior to any sale or other disposition of any Note held by any Purchaser or such Person’s nominee, such Person will, at its election, either endorse thereon the amount of principal paid
thereon and the last date to which interest has been paid thereon or surrender such Note to the Company in exchange for a new Note or Notes pursuant to Section 13.2. The Company will afford the benefits of this Section 14.2 to any

Company without regard to whether such Note has been marked to indicate such amendment or waiver. No such amendment or waiver will extend to or affect any obligation, covenant, agreement, Default or Event of Default not expressly amended or waived

Subsidiary Guaranty and this Agreement. Each holder of a Note, by its acceptance of a Note, will be deemed to have agreed to be bound by and to be entitled to the benefits of this Section 20 as though it were a party to this Agreement. On
reasonable request by the Company in connection with the delivery to any holder of a Note of information required to be delivered to such holder under this Agreement or requested by such holder (other than a holder that is a party to this Agreement
or its nominee), such holder will enter into an agreement with the Company embodying the provisions of this Section 20. 
  

	SECTION 21.	SUBSTITUTION OF PURCHASER. 

 Each Purchaser shall have the right to substitute any one of its Affiliates as the purchaser of the Notes that it has agreed to purchase hereunder, by written notice to the Company, which notice shall be signed by
both such Purchaser and such Affiliate, shall contain such Affiliate’s agreement to be bound by this Agreement and shall contain a confirmation by such Affiliate of the accuracy with respect to it of the representations set forth in
Section 6. Upon receipt of such 

  

 -38- 

 
notice, any reference to such Purchaser in this Agreement (other than in this Section 21), shall be deemed to refer to such Affiliate in lieu of such
original Purchaser. In the event that such Affiliate is so substituted as a Purchaser hereunder and such Affiliate thereafter transfers to such original Purchaser all of the Notes then held by such Affiliate, upon receipt by the Company of notice of
such transfer, any reference to such Affiliate as a “Purchaser” in this Agreement (other than in this Section 21), shall no longer be deemed to refer to such Affiliate, but shall refer to such original Purchaser, and such original
Purchaser shall again have all the rights of an original holder of the Notes under this Agreement. 
  

	SECTION 22.	MISCELLANEOUS. 

 Section 22.1. Successors and Assigns. All covenants and other agreements contained in this Agreement by or on behalf of any of the parties hereto bind and inure to the benefit of their respective successors and assigns
(including, without limitation, any subsequent holder of a Note) whether so expressed or not. 
 Section 22.2. Payments Due on
Non-Business Days. Anything in this Agreement or the Notes to the contrary notwithstanding (but without limiting the requirement in Section 8.4 that the notice of any optional prepayment specify a Business Day as the date fixed for such
prepayment), any payment of principal of or Make-Whole Amount or interest on any Note that is due on a date other than a Business Day shall be made on the next succeeding Business Day without including the additional days elapsed in the computation
of the interest payable on such next succeeding Business Day; provided that if the maturity date of any Note is a date other than a Business Day, the payment otherwise due on such maturity date shall be made on the next succeeding Business Day and
shall include the additional days elapsed in the computation of interest payable on such next succeeding Business Day. 
 Section 22.3. Accounting Terms. All accounting terms used herein which are not expressly defined in this Agreement have the meanings respectively given to them in accordance with GAAP. Except as otherwise specifically provided
herein, (i) all computations made pursuant to this Agreement shall be made in accordance with GAAP, and (ii) all financial statements shall be prepared in accordance with GAAP. 
 Section 22.4. Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall (to the full extent permitted by law) not
invalidate or render unenforceable such provision in any other jurisdiction. 
 Section 22.5. Construction. Each covenant
contained herein shall be construed (absent express provision to the contrary) as being independent of each other covenant contained herein, so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to
excuse compliance with any other covenant. Where any provision herein refers to action to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly
by such Person. 
  

 -39- 

 For the avoidance of doubt, all Schedules and Exhibits attached to this Agreement shall be deemed to be a
part hereof. 
 Section 22.6. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be
an original but all of which together shall constitute one instrument. Each counterpart may consist of a number of copies hereof, each signed by less than all, but together signed by all, of the parties hereto. 
 Section 22.7. Governing Law. This Agreement shall be construed and enforced in accordance with, and the rights of the parties shall be
governed by, the law of the State of New York excluding choice-of-law principles of the law of such State that would permit the application of the laws of a jurisdiction other than such State. 
 Section 22.8. Jurisdiction and Process; Waiver of Jury Trial. (a) The Company irrevocably submits to the non-exclusive jurisdiction of
any New York State or federal court sitting in the Borough of Manhattan, The City of New York, over any suit, action or proceeding arising out of or relating to this Agreement or the Notes. To the fullest extent permitted by applicable law, the
Company irrevocably waives and agrees not to assert, by way of motion, as a defense or otherwise, any claim that it is not subject to the jurisdiction of any such court, any objection that it may now or hereafter have to the laying of the venue of
any such suit, action or proceeding brought in any such court and any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. 
 (b) The Company consents to process being served by or on behalf of any holder of Notes in any suit, action or proceeding of the nature referred to in
Section 22.8(a) by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, return receipt requested, to it at its address specified in Section 18 or at such other address of
which such holder shall then have been notified pursuant to said Section. The Company agrees that such service upon receipt (i) shall be deemed in every respect effective service of process upon it in any such suit, action or proceeding and
(ii) shall, to the fullest extent permitted by applicable law, be taken and held to be valid personal service upon and personal delivery to it. Notices hereunder shall be conclusively presumed received as evidenced by a delivery receipt
furnished by the United States Postal Service or any reputable commercial delivery service. 
 (c) Nothing in this Section 22.8 shall
affect the right of any holder of a Note to serve process in any manner permitted by law, or limit any right that the holders of any of the Notes may have to bring proceedings against the Company in the courts of any appropriate jurisdiction or to
enforce in any lawful manner a judgment obtained in one jurisdiction in any other jurisdiction. 
 (d) THE
PARTIES HERETO HEREBY WAIVE TRIAL BY JURY IN ANY ACTION BROUGHT ON
OR WITH RESPECT TO THIS AGREEMENT, THE NOTES OR ANY OTHER DOCUMENT
EXECUTED IN CONNECTION HEREWITH OR THEREWITH. 
 *     *     *     *     * 
  

 -40- 

 The execution hereof by the Purchasers shall constitute a contract among the Company and the Purchasers
for the uses and purposes hereinabove set forth. This Agreement may be executed in any number of counterparts, each executed counterpart constituting an original but all together only one agreement.

such unpaid balance and on any overdue payment of any Make-Whole Amount, at a rate per annum from time to time equal to the greater of (i) 8.24%, or (ii) 2% over the rate of interest publicly announced by Bank of America, N.A. from time to

provided in the Note Purchase Agreement.

holder hereof shall be governed by, the law of the State of New York excluding choice-of-law principles of the law of such State that would require the application of the laws of a jurisdiction other than such State.

COUNSEL 
 TO THE COMPANY 
 The closing opinion of Kelly Hart & Hallman LLP, special counsel to the Company, which is called for by Section 4.4 of the Note Purchase
Agreement, shall be dated the date of Closing and addressed to the Purchasers, shall be satisfactory in scope and form to each Purchaser and shall be to the effect that: 
 1. The Company is a corporation, duly incorporated, validly existing and in good standing under the laws of its jurisdiction of incorporation and has the corporate power and authority to execute and perform the Note
Purchase Agreement and to issue the Notes. The Company has the full corporate power and the corporate authority to conduct the activities in which it is now engaged and is duly licensed or qualified and is in good standing as a foreign corporation
in each jurisdiction in which the character of the properties owned or leased by it or the nature of the business transacted by it makes such licensing or qualification necessary except in jurisdictions where the failure to be so qualified or
licensed would not have a material adverse effect on the business of the Company. 
 2. Each Subsidiary is a corporation or similar legal
entity, duly organized, validly existing and in good standing under the laws of its jurisdiction of organization, and is duly licensed or qualified and is in good standing in each jurisdiction in which the character of the properties owned or leased
by it or the nature of the business transacted by it makes such licensing or qualification necessary except in jurisdictions where the failure to be so qualified or licensed would not have a material adverse effect on the business of such
Subsidiary. All of the issued and outstanding shares of capital stock or similar equity interests of each such Subsidiary have been duly issued, are fully paid and non-assessable and are owned by the Company, by one or more Subsidiaries, or by the
Company and one or more Subsidiaries. 
 3. The issuance and sale of the Notes, the execution, delivery and performance by the Company of the
Note Purchase Agreement, and the execution, delivery and performance by each Subsidiary Guarantor of the Subsidiary Guaranty do not violate any provision of any law or other rule or regulation of any Governmental Authority applicable to the Company
or any such Subsidiary Guarantor or conflict with or result in any breach of any of the provisions of or constitute a default under or result in the creation or imposition of any Lien upon any property of the Company or any such Subsidiary Guarantor
pursuant to the provisions of the Articles or Certificate of Incorporation or By-laws, or such similar organizational or governing instrument, as the case may be, of the Company or such Subsidiary Guarantor or any agreement or other instrument known
to such counsel to which the Company or any such Subsidiary Guarantor is a party or by which the Company or any such Subsidiary Guarantor may be bound. 
 4. There are no actions, suits or proceedings pending or, to the knowledge of such counsel after due inquiry, threatened against or affecting the Company or any Subsidiary in any court or before any governmental
authority or arbitration board or tribunal which, if adversely determined, would have a materially adverse effect on the properties, business, profits or condition, (financial or otherwise) of the Company and its Subsidiaries or the ability of the
Company to perform its obligations under the Note Purchase Agreement and the Notes or on the 

  

 EXHIBIT 4.4(b) 
 (to Note Purchase Agreement) 

 
legality, validity or enforceability of the Company’s obligations under the Note Purchase Agreement and the Notes. To the knowledge of such counsel,
neither the Company nor any Subsidiary is in default with respect to any court or governmental authority, or arbitration board or tribunal. 
 5. The Note Purchase Agreement has been duly authorized by all necessary corporate action on the part of the Company, has been duly executed and delivered by the Company and constitutes the legal, valid and binding contract of the Company
enforceable against the Company in accordance with its terms, subject to bankruptcy, insolvency, fraudulent conveyance and similar laws affecting creditors’ rights generally, and general principles of equity (regardless of whether the
application of such principles is considered in a proceeding in equity or at law). 
 6. The Notes have been duly authorized by all necessary
corporate action on the part of the Company, have been duly executed and delivered by the Company and constitute the legal, valid and binding contract of the Company enforceable against the Company in accordance with their terms, subject to
bankruptcy, insolvency, fraudulent conveyance and similar laws affecting creditors’ rights generally, and general principles of equity (regardless of whether the application of such principles is considered in a proceeding in equity or at law).

 7. The Subsidiary Guaranty has been duly authorized by all necessary corporate or other organizational action on the part of each
Subsidiary Guarantor, has been duly executed and delivered by each Subsidiary Guarantor and constitutes the legal, valid and binding contract of each such Subsidiary Guarantor enforceable against such Subsidiary Guarantor in accordance with its
terms, subject to bankruptcy, insolvency, fraudulent conveyance and similar laws affecting creditors’ rights generally, and general principles of equity (regardless of whether the application of such principles is considered in a proceeding in
equity or at law). 
 8. No approval, consent or withholding of objection on the part of, or filing, registration or qualification with, any
governmental body, Federal or state, is necessary in connection with the execution and delivery of the Note Purchase Agreement, the Notes or the Subsidiary Guaranty. 
 9. The issuance, sale and delivery of the Notes and the execution and delivery of the Subsidiary Guaranty by the Subsidiary Guarantors under the circumstances contemplated by the Note Purchase Agreement and the
Subsidiary Guaranty do not, under existing law, require the registration of the Notes or the Subsidiary Guaranty under the Securities Act of 1933, as amended, or the qualification of an indenture under the Trust Indenture Act of 1939, as amended.

 10. Neither the issuance of the Notes nor the application of the proceeds of the sale of the Notes will violate or result in a violation
of Section 7 of the Securities Exchange Act of 1934, as amended, or any regulation issued pursuant thereto, including, without limitation, Regulation T, U or X of the Board of Governors of the Federal Reserve System. 
  

 E-4.4(b)-2 

 11. The Company is not an “investment company” or a company “controlled” by an
“investment company,” within the meaning of the Investment Company Act of 1940, as amended. 
 The opinion of Kelly Hart &
Hallman LLP, shall cover such other matters relating to the sale of the Notes as each Purchaser may reasonably request and successors and assigns of the Purchasers shall be entitled to rely on such opinion. With respect to matters of fact on which
such opinion is based, such counsel shall be entitled to rely on appropriate certificates of public officials and other officers of the Company and its Subsidiaries.

 3. The Notes have been duly authorized by all necessary corporate action on the part of the Company, and the Notes being delivered on the date hereof
have been duly executed and delivered by the Company and constitute the legal, valid and binding obligations of the Company enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent conveyance and similar laws
affecting creditors’ rights generally, and general principles of equity (regardless of whether the application of such principles is considered in a proceeding in equity or at law). 
 4. The issuance, sale and delivery of the Notes and the execution and delivery of the Subsidiary Guaranty under the circumstances contemplated by the
Note Purchase Agreement and the Subsidiary Guaranty do not, under existing law, require the registration of the Notes or the Subsidiary Guaranty under the Securities Act of 1933, as amended, or the qualification of an indenture under the Trust
Indenture Act of 1939, as amended. 
 EXHIBIT 4.4(c)
