Ladies and Gentlemen:

MSA SAFETY INCORPORATED, a Pennsylvania corporation (together with its successors and assigns, the “Company”)and MINE SAFETY APPLIANCES COMPANY, LLC, a Pennsylvania limited liability company (as successor to Mine Safety Appliances Company, a Pennsylvania corporation) (together with its successors and assigns, “MSA”), agreeagrees with Prudential and each of the Purchasers as set forth below.

Subject to the terms and conditions hereof, the Company, MSA and the Purchasers desire to enter into this Agreement to (a) amend and restate the Existing Note Purchase and Private Shelf Agreement and amend the Existing Series A Notes as provided by this Agreement, (b) provide for the issuance of £54,945,054.94 in aggregate principal amount of the Company’s 3.40% Series B Senior Notes due 2031 on the Restatement Effective Date and (c) provide for the issuance of additional Shelf Notes from time to time as provided herein.

1. BACKGROUND; AMENDMENT AND RESTATEMENT; CONSENTS.

1.1. Original Note Purchase and Private Shelf Agreement; Original Series A Notes. MSA and the Original Purchasers previously entered into that certain Note Purchase and Private Shelf Agreement dated as of October 13, 2010, as amended by that certain Amendment No. 1 to Note Purchase and Private Shelf Agreement dated as of April 5, 2012, Amendment No. 2 to Note Purchase and Private Shelf Agreement dated as of April, 4, 2013, and Amendment No. 3 and Waiver to Note Purchase Agreement dated as of February 12, 2014 (as so amended, the “Original

Note Purchase and Private Shelf Agreement”)pursuant to which MSA issued $100,000,000 in original aggregate principal amount of its 4.00% Series A Senior Notes due October 13, 2021 (all such notes, whether initially issued, or issued in substitution thereof pursuant to the Original Note Purchase and Private Shelf Agreement, the “Original Series A Notes”) to the Original Purchasers on the Series A Closing Day.

On the First Restatement Date, the Original Note Purchase and Private Shelf Agreement was amended and restated in its entirety pursuant to the terms of that certain Amended and Restated Note Purchase and Private Shelf Agreement (as amended by that certain Amendment No. 1 to Amended and Restated Note Purchase and Private Shelf Agreement dated as of December 11, 2015, the “Existing Note Purchase and Private Shelf Agreement”)which continues in full force and effect without rescission or novation thereof as of the date hereof. Pursuant to the terms of the Existing Note Purchase and Private Shelf Agreement, (a) MSA assigned all of MSA’s obligations,inter alia, under the Original Series A Notes and the Original Note Purchase and Private Shelf Agreement to the Company, and the Company assumed, and agreed to be liable for, all of the obligations, liabilities and undertakings of MSA, whether now existing or hereafter arising, arising under and in respect of the Original Note Purchase and Private Shelf Agreement and the Original Series A Notes (in each case, as amended and restated pursuant to the Existing Note Purchase and Private Shelf Agreement), and (b) the Original Series A Notes were amended and restated to conform to and have the terms provided in those certain Amended and Restated 4.00% Series A Senior Notes due October 13, 2021 substantially in the form ofExhibit 1-A to the Existing Note Purchase and Private Shelf Agreement (as so amended and restated and in effect immediately prior to giving effect to this Agreement, the “Existing Series A Notes”), and the Company issued and delivered to each holder of the Original Series A Note, a new Series A Note in the form ofExhibit 1-A to the Existing Note Purchase and Private Shelf Agreement in exchange for, and in replacement of, each Original Series A Note held by such holder. The outstanding principal balance of the Existing Series A Notes as of the date hereof is $100,000,000. In addition, the Company had previously authorized the issuance and sale of up to $175,000,000 in aggregate principal amount of its additional senior promissory notes upon the terms and subject to the conditions set forth in the Existing Note Purchase and Private Shelf Agreement (the “Existing Shelf Facility”). No additional senior promissory notes were issued under the Existing Shelf Facility prior to the Restatement Effective Date.

1.2. Amendment and Restatement of Existing Note Purchase and Private Shelf Agreement; Amendment of Existing Series A Notes. Effective on the Restatement Effective Date upon satisfaction of the conditions set forth in Section 5, this Agreement shall, and hereby does, amend, restate and replace in its entirety the Existing Note Purchase and Private Shelf Agreement which, as so amended and restated by this Agreement, continues in full force and effect without rescission or novation thereof. Further, the Existing Series A Notes are hereby, without any further action required on the part of any other Person, deemed to be automatically amended to conform to and have the terms provided inExhibit 1-A hereto (as so amended and as amended by the First Amendment and as may be further amended, restated, supplemented or otherwise modified from time to time, including any such notes issued in substitution therefor pursuant to Section 14 of this Agreement, the “Series A Notes”). Any Series A Note issued on or after the Restatement Effective Date shall be in the form ofExhibit 1-A hereto (as amended by the First Amendment). If requested by any holder of the Series A Notes, the Company will issue a replacement Series A Note or Series A Notes in favor of each record holder of an Existing Series A Note or Existing Series A Notes for such holder’s Existing Series

The Series B Notes shall be substantially in the form set out inExhibit 1-B (as amended by the First Amendment).For purposes of authorizing the transactions contemplated by this Agreement, the issuance of the Series B Notes shall be deemed to constitute an issuance of senior promissory notes under the Existing Shelf Facility which reduces the aggregate principal amount of notes that may be issued under the Existing Shelf Facility from $175,000,000 to $95,000,000 and, concurrent with the effectiveness of this Agreement on the Restatement Effective Date and the issuance of the Series B Notes as contemplated hereby, the Existing Shelf Facility shall be amended and restated upon the terms and conditions set forth herein

In the event that a Request for Purchase shall include a request for Shelf Notes denominated in Sterling, Euros or Australian Dollars, the Quotation provided by Prudential shall also specify the Designated Gilt(s), Designated Euro Securities or Designated Australian Securities, as the case may be, the proposed Closing Day and the rate of exchange used by Prudential in calculating the approximate Sterling Equivalent, Euro Equivalent or Australian Dollar Equivalent of the requested principal amount of such Shelf Note (it being understood that the final Sterling Equivalent, Euro Equivalent or Australian Dollar Equivalent, as the case may be, of such requested principal amount shall be determined by Prudential at the time the Company accepts the relevant Quotation pursuant to Section 3.2(e)).

(e)Acceptance. Within the Acceptance Window, an Authorized Officer of the Company may, subject to Section 3.2(f), elect to accept on behalf of the Company a Quotation as to not less than $5,000,000 (or its equivalent in another Applicable Currency as determined at the rate of exchange determined by Prudential at the time the Company accepts the relevant Quotation pursuant hereto) aggregate principal amount of the Shelf Notes specified in the related Request for Purchase (each such Shelf Note being herein called an “Accepted Note” and such acceptance being herein called an “Acceptance”). The day the Company notifies Prudential of an Acceptance with respect to any Accepted Notes is herein called the “Acceptance Day” for such Accepted Notes. Any Quotation as to which Prudential does not receive an Acceptance within the Acceptance Window shall

6

expire, and no purchase or sale of Shelf Notes hereunder shall be made based on any such expired Quotation. Subject to Section 3.2(f) and the other terms and conditions hereof, the Company agrees to sell to a Prudential Affiliate, and Prudential agrees to cause the purchase by a Prudential Affiliate of, the Accepted Notes at 100% of the principal amount of such Shelf Notes, which purchase price shall be paid in the Applicable Currency in which such Shelf Notes are denominated. As soon as practicable following the Acceptance Day, the Company, Prudential and each Prudential Affiliate which is to purchase any such Accepted Notes will execute a confirmation of such Acceptance substantially in the form ofExhibit 3 attached hereto (herein called a “Confirmation of Acceptance”). If the Company should fail to execute and return to Prudential within three Business Days following the Company’s receipt thereof a Confirmation of Acceptance with respect to any Accepted Notes, Prudential may at its election at any time prior to Prudential’s receipt thereof cancel the closing with respect to such Accepted Notes by so notifying the Company in writing.

(f)Market Disruption. Notwithstanding the provisions of Section 3.2(e), any Quotation provided pursuant to Section 3.2(d) shall expire if, prior to the time an Acceptance with respect to such Quotation shall have been notified to Prudential in accordance with Section 3.2(e), (a) the domestic market for U.S. Treasury securities or derivatives shall have closed or there shall have occurred a general suspension, material limitation, or significant disruption of trading in securities generally on the New York Stock Exchange or in the domestic market for U.S. Treasury securities or derivatives, or (b) in the case of any Shelf Notes to be denominated in a currency other than Dollars, the markets for the relevant government securities of any Series of Shelf Notes specified in such Quotation (which (x) in the case of Shelf Notes to be denominated in Sterling, shall be U.K. gilt-edged securities, (y) in the case of Shelf Notes to be denominated in Euros, shall be the German Bunds and (z) in the case of Shelf Notes to be denominated in Australian Dollars, shall be Australian government bonds) or the spot and forward currency market, the financial futures market or the interest rate swap market shall have closed or there shall have occurred a general suspension, material limitation, or significant disruption of trading. No purchase or sale of Shelf Notes hereunder shall be made based on such expired Quotation. If the Company thereafter notifies Prudential of the Acceptance of any such Quotation, such Acceptance shall be ineffective for all purposes of this Agreement, and Prudential shall promptly notify the Company that the provisions of this Section 3.2(f) are applicable with respect to such Acceptance.

(g)Fees.

(i) [Reserved].

(ii) Issuance Fee. The Company will pay to each Purchaser in immediately available funds a fee (herein called the “Issuance Fee”) on each Closing Day (including the Restatement Effective Date) in an amount equal to 0.10% of the aggregate principal amount of Shelf Notes sold to such Purchaser on such Closing Day. The Issuance Fee shall be payable in Dollars.

7

(iii) Delayed Delivery Fee. If the closing of the purchase and sale of any Accepted Note is delayed for any reason beyond the original Closing Day for such Accepted Note, the Company will pay to each Purchaser which shall have agreed to purchase such Accepted Note on the Cancellation Date or actual closing date of such purchase and sale, an amount (herein called the “Delayed Delivery Fee”) equal to:

(A) in the case of an Accepted Note denominated in Dollars, the product of (1) the amount determined by Prudential to be the amount by which the bond equivalent yield per annum of such Accepted Note exceeds the investment rate per annum on an alternative Dollar investment of the highest quality selected by Prudential and having a maturity date or dates the same as, or closest to, the Rescheduled Closing Day from time to time fixed for the delayed delivery of such Accepted Note, (2) the principal amount of such Accepted Note, and (3) a fraction the numerator of which is equal to the number of actual days elapsed from and including the original Closing Day for such Accepted Note to but excluding the date of such payment, and the denominator of which is 360; and

(B) in the case of an Accepted Note denominated in a currency other than Dollars, the sum of (1) the product of (x) the amount by which the bond equivalent yield per annum of such Accepted Note exceeds the arithmetic average of the Overnight Investment Rates on each day from and including the original Closing Day for such Accepted Note, (y) the principal amount of such Accepted Note, and (z) a fraction the numerator of which is equal to the number of actual days elapsed from and including the original Closing Day for such Accepted Note to but excluding the date of such payment, and the denominator of which is 360 (in case of any Accepted Note denominated in Euros) or 365 (in the case of any Accepted Note denominated in Sterling or Australian Dollars) and (2) the reasonable costs and expenses (if any) incurred by such Purchaser or its affiliates with respect to any interest rate, currency exchange or similar agreement entered into by the Purchaser or any such affiliate in connection with the delayed closing of such Accepted Notes. The portion of the Delayed Delivery Fee described in clause (iii)(B)(1) shall be paid in the currency in which the Accepted Notes are denominated.

In no case shall the Delayed Delivery Fee be less than zero. Nothing contained herein shall obligate any Purchaser to purchase any Accepted Note on any day other than the Closing Day for such Accepted Note, as the same may be rescheduled from time to time in compliance with Section 4.3.

(iv) Cancellation Fee. If the Company at any time notifies Prudential in writing that the Company is canceling the closing of the purchase and sale of any Accepted Note, or if Prudential notifies the Company in writing under the circumstances set forth in the last sentence of Section 3.2(e) or the penultimate sentence of Section 4.3 that the closing of the purchase and sale of such Accepted

8

Note is to be canceled, or if the closing of the purchase and sale of such Accepted Note is not consummated on or prior to the last day of the Issuance Period (the date of any such notification, or the last day of the Issuance Period, as the case may be, being herein called the “Cancellation Date”), the Company will pay to each Purchaser which shall have agreed to purchase such Accepted Note no later than one day after the Cancellation Date in immediately available funds an amount (the “Cancellation Fee”) equal to

(A) in the case of an Accepted Note denominated in Dollars, the product of (1) the principal amount of such Accepted Note and (2) the quotient (expressed in decimals) obtained by dividing (y) the excess of the ask price (as determined by Prudential) of the Hedge Treasury Note(s) on the Cancellation Date over the bid price (as determined by Prudential) of the Hedge Treasury Note(s) on the Acceptance Day for such Accepted Note by (z) such bid price, with the foregoing bid and ask prices as reported by Tradeweb LLC, or if such information ceases to be available through Tradeweb LLC, any publicly available source of such market data selected by Prudential, and rounded to the second decimal place; and

(B) in the case of an Accepted Note denominated in a currency other than Dollars, the aggregate of all unwinding costs incurred by such Purchaser or its affiliates on positions executed by or on behalf of such Purchaser or such affiliates in connection with the proposed lending in such currency and setting the coupon in such currency (including replacement positions entered into for purposes of achieving short form hedge account treatment under FAS133), provided,however, that any gain realized upon the unwinding of any such positions shall be offset against any such unwinding costs. Such positions include (without limitation) currency and interest rate swaps, futures and forwards, government bond (including U.S. Treasury bond) hedges and currency exchange contracts, all of which may be subject to substantial price volatility. Such costs may also include (without limitation) losses incurred by such Purchaser or its affiliates as a result of fluctuations in exchange rates. All unwinding costs incurred by such Purchaser shall be reasonably determined by Prudential or its affiliate in accordance with generally accepted financial practice.

In no case shall the Cancellation Fee be less than zero.

Such implied yield will be determined, if necessary, by (A) converting quotations to bond-equivalent yields in accordance with accepted financial practice and (B) interpolating linearly between (1) the actively traded benchmark Australian government bonds with the maturity closest to and greater than the Remaining Average Life of such Called Principal and (2) the actively traded benchmark Australian government bonds with the maturity closest to and less than the Remaining Average Life of such Called Principal.

“Original Swap Agreement” means, with respect to any Swapped Note, (x) a cross-currency swap agreement and annexes and schedules thereto (an“Initial Swap Agreement”)that is entered into on an arm’s length basis by the original purchaser of such Swapped Note (or any affiliate thereof) in connection with the purchase of such Swapped Note with a creditworthy leading dealer in the relevant foreign currency exchange market

Any holder of a Swapped Note that enters into, assumes, novates or terminates an Original Swap Agreement or Replacement Swap Agreement shall within a reasonable period of time thereafter deliver to the Company a notice confirming the assumption, novation or termination related thereto.

“Swap Agreement” means, with respect to any Swapped Note, an Original Swap Agreement or a New Swap Agreement, as the case may be.

“Swapped Note” means any Note that as of the applicable Closing Day is subject to a Swap Agreement. A“Swapped Note” shall no longer be deemed a“Swapped

“Swapped Note Reinvestment Yield” means, with respect to the Swapped Note Called Notional Amount of any Swapped Note, the sum of (x) 0.50% (50 basis points) plus (y) the yield to maturity implied by (1) the yields reported, as of 10.00 A.M. (New York City time) on the second Business Day preceding the Swapped Note Settlement Date with respect to such Swapped Note Called Notional Amount, on the display designated as “Page PX1” (or such other display as may replace Page PX1) on the Bloomberg Financial Markets for the most recently issued actively traded on the run U.S. Treasury securities having a maturity equal to the Swapped Note Remaining Average Life of such Swapped Note Called Notional Amount as of such Swapped Note Settlement Date, or (2) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable (including by way of interpolation), 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 Swapped Note Settlement Date with respect to such Swapped Note Called Notional Amount, in U.S. Federal Reserve Statistical Release H.15(519) (or any comparable successor publication) for applicable U.S. Treasury securities having a constant maturity equal to the Swapped Note Remaining Average Life of such Swapped Note Called Notional Amount as of such Swapped Note Settlement Date.

In the case of each determination under clause (1) or (2), as the case may be, of the preceding paragraph such implied 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 between (i) the applicable U.S. Treasury security with the maturity closest to and greater than the Swapped Note Remaining Average Life of such Swapped Note Called Notional Amount and (ii) the applicable U.S. Treasury security with the maturity closest to and less than such Swapped Note Remaining Average Life. The Swapped Note Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of such Swapped Note.

33

“Swapped Note Remaining Average Life” means, with respect to any Swapped Note Called Notional Amount, the number of years (calculated to the nearest one-twelfth year) obtained by dividing (x) such Swapped Note Called Notional Amount into (y) the sum of the products obtained by multiplying (1) the principal component of each Swapped Note Remaining Scheduled Swap Payment with respect to such Swapped Note Called Notional Amount by (2) the number of years (calculated to the nearest one-twelfth year) that will elapse between the Swapped Note Settlement Date with respect to the related Swapped Note Called Principal and the scheduled due date of such Swapped Note Remaining Scheduled Payments.

“Swapped Note Settlement Date” means, with respect to the Swapped Note Called Principal of any Swapped Note, the date on which such Swapped Note Called Principal is to be prepaid pursuant to Section 9.2 or Section 9.7 or has become or is declared to be immediately due and payable pursuant to Section 13.1, as the context requires.

9.7. Prepayment on a Change in Control.

34

Amount due in connection with such prepayment (calculated as if the date of such Company Notice were the date of the prepayment), setting forth the details of such computation. If a holder does not notify the Company as provided above, then the holder shall be deemed to have accepted such offer.

(b) Two Business Days prior to the prepayment date specified in the Company Notice, the Company shall deliver to each holder of Notes to be prepaid a certificate of a Senior Financial Officer specifying the calculation of such Make-Whole Amount as of the prepayment date.

(c) On the prepayment date specified in the Company Notice, the entire unpaid principal amount of the Notes held by each holder of Notes who has accepted such prepayment offer (in accordance with paragraph (a) above), together with interest thereon to the prepayment date with respect to each such Note and the Make-Whole Amount with respect thereto shall become due and payable.

Each holder of a Swapped Note shall be responsible for calculating its own Swap Breakage Amount in Dollars upon the prepayment or repayment of all or any portion of such Swapped Note, and such calculation as reported to the Company in reasonable detail shall be binding on the Company absent demonstrable error.

As used in this Section 9.8 with respect to any Swapped Note that is prepaid or accelerated:“Net Loss” means the amount, if any, by which the Swapped Note Called Notional Amount exceeds the sum of (x) the Swapped Note Called Principal plus (or minus in the case of an amount paid) (y) the Swap Breakage Amount received (or paid) by the holder of such Swapped Note; and“Net Gain” means the amount, if any, by which the Swapped Note Called Notional Amount is exceeded by the sum of (x) the Swapped Note Called Principal plus (or minus in the case of an amount paid) (y) the Swap Breakage Amount received (or paid) by such holder. For purposes of any determination of any“Net Loss” or “Net Gain,” the Swapped Note Called Principal shall be determined by the holder of the affected Swapped Note by converting the Applicable Currency into Dollars at the current Applicable Currency/Dollar exchange rate, as determined as of 10:00 A.M. (New York City time) on the day such Swapped Note is prepaid or accelerated as indicated on the applicable screen of Bloomberg Financial Markets and any such calculation shall be reported to the Company in reasonable detail and shall be binding on the Company absent demonstrable error.

35

As used in this Section 9.8,“Swap Breakage Amount” means, with respect to the Swap Agreement associated with any Swapped Note, in determining the Net Loss or Net Gain, the amount that would be received (in which case the Swap Breakage Amount shall be positive) or paid (in which case the Swap Breakage Amount shall be negative) by the holder of such Swapped Note as if such Swap Agreement had terminated in whole or in relation to the occurrence of an event of default or an early termination under the ISDA 1992 Multi-Currency Cross Border Master Agreement or ISDA 2002 Master Agreement, as applicable (the“ISDA Master Agreement”);provided, that if such holder (or its predecessor in interest with respect to such Swapped Note) was, but is not at the time, a party to an Original Swap Agreement but is a party to a New Swap Agreement, then the Swap Breakage Amount shall mean thelesser of (x) the gain or loss (if any) which would have been received or incurred (by payment, through off-set or netting or otherwise) by the holder of such Swapped Note under the terms of the Original Swap Agreement (if any) in respect of such Swapped Note to which such holder (or any affiliate thereof) was a party (or if such holder was never a party to an Original Swap Agreement, then the last Original Swap Agreement to which the most recent predecessor in interest to such holder as a holder of a Swapped Note was a party) and which would have arisen as a result of the payment of the Swapped Note Called Principal on the Swapped Note Settlement Date and (y) the gain or loss (if any) actually received or incurred by the holder of such Swapped Note, in connection with the payment of such Swapped Note Called Principal on the Swapped Note Settlement Date, under the terms of the New Swap Agreement to which such holder (or any affiliate thereof) is a party. The holder of such Swapped Note will make all calculations related to the Swap Breakage Amount in good faith and in accordance with its customary practices for calculating such amounts under the ISDA Master Agreement pursuant to which such Swap Agreement shall have been entered into and assuming for the purpose of such calculation that there are no other transactions entered into pursuant to such ISDA Master Agreement (other than the Swap Agreement with respect to such Swapped Note).

Upon receipt of such notice, any reference to such Purchaser in this Agreement (other than in this Section 22), 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 22), 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.

NOW THEREFORE, in compliance with the Note Purchase Agreement, and in consideration of, the execution and delivery of the Note Purchase Agreement and the purchase of the Notes by each of the Purchasers, the Guarantor hereby covenants and agrees with, and represents and warrants to, each of the holders as follows:

1. GUARANTEE; INDEMNITY.

1.1 GUARANTEE.The Guarantor hereby irrevocably and unconditionally guarantees to each holder, the due and punctual payment in full of (a) the principal of, Make-Whole Amount, if any, and interest on (including, without limitation, interest accruing after the filing of any petition in bankruptcy, or the commencement of any insolvency, reorganization or like proceeding, whether or not a claim for post-filing or post-petition interest is allowed in such proceeding), and any other amounts due under, the Notes when and as the same shall become due and payable (whether at stated maturity or by required or optional prepayment or by acceleration or otherwise) and (b) any other sums which may become due under the terms and provisions of the Notes, the Note Purchase Agreement or any other instrument referred to therein (all such obligations described in clauses (a) and (b) above are herein called the“Guaranteed Obligations”). The guarantee in the preceding sentence is an absolute, present and continuing guarantee of payment and not of collectability and is in no way conditional or contingent upon any

2

attempt to collect from the Company or any other guarantor of the Notes or upon any other action, occurrence or circumstance whatsoever. In the event that the Company shall fail so to pay any of such Guaranteed Obligations, the Guarantor agrees to pay the same when due to the holders entitled thereto, without demand, presentment, protest or notice of any kind, in lawful money of the United States of America, pursuant to the requirements for payment specified in the Notes and the Note Purchase Agreement. Each default in payment of any of the Guaranteed Obligations shall give rise to a separate cause of action hereunder and separate suits may be brought hereunder as each cause of action arises. The Guarantor agrees that the Notes issued in connection with the Note Purchase Agreement may (but need not) make reference to this Guarantee Agreement.

The Guarantor agrees to pay and to indemnify and save each holder harmless from and against any damage, loss, cost or expense (including attorneys’ fees) which such holder may incur or be subject to as a consequence, direct or indirect, of (x) any breach by the Guarantor or by the Company of any warranty, covenant, term or condition in, or the occurrence of any default under, this Guarantee Agreement, the Notes, the Note Purchase Agreement or any other instrument referred to therein, together with all expenses resulting from the compromise or defense of any claims or liabilities arising as a result of any such breach or default, (y) any legal action commenced to challenge the validity or enforceability of this Guarantee Agreement, the Notes, the Note Purchase Agreement or any other instrument referred to therein and (z) enforcing or defending (or determining whether or how to enforce or defend) the provisions of this Guarantee Agreement.

The Guarantor hereby acknowledges and agrees that the Guarantor’s liability hereunder is joint and several with any other Person(s) who may guarantee the obligations and Indebtedness under and in respect of the Notes and the Note Purchase Agreement.

Notwithstanding the foregoing provisions or any other provision of this Guarantee Agreement, the holders (by their acceptance of any Note) and the Guarantor hereby agree that if at any time the Guaranteed Obligations exceed the Maximum Guaranteed Amount determined as of such time with regard to the Guarantor, then this Guarantee Agreement shall be automatically amended to reduce the Guaranteed Obligations to the Maximum Guaranteed Amount. Such amendment shall not require the written consent of the Guarantor or any holder and shall be deemed to have been automatically consented to by the Guarantor and each holder. The Guarantor agrees that the Guaranteed Obligations may at any time exceed the Maximum Guaranteed Amount without affecting or impairing the obligation of the Guarantor.“Maximum Guaranteed Amount” means as of the date of determination with respect to the Guarantor, the lesser of (a) the amount of the Guaranteed Obligations outstanding on such date and (b) the maximum amount that would not render the Guarantor’s liability under this Guarantee Agreement subject to avoidance under Section 548 of the United States Bankruptcy Code (or any successor provision) or any comparable provision of applicable state law.

3

1.2 INDEMNITY. The Guarantor hereby further agrees that if, for any reason, any amount claimed by a holder of the Notes under this Guarantee Agreement is not recoverable on the basis of a guarantee, it will be liable as a principal debtor and primary obligor to indemnify that holder of the Notes against any cost, loss or liability it incurs as a result of the Company not paying any amount expressed to be payable by it under the Notes, the Note Purchase Agreement or otherwise on the date when it is expressed to be due. The amount payable by the Guarantor under this Section 1.2 will not exceed the amount it would have had to pay under Section 1.1 if the amount claimed had been recoverable on the basis of a guarantee.

2. OBLIGATIONS ABSOLUTE.

The obligations of the Guarantor hereunder shall be primary, absolute, irrevocable and unconditional, irrespective of the validity or enforceability of the Notes, the Note Purchase Agreement or any other instrument referred to therein, shall not be subject to any counterclaim, setoff, deduction or defense based upon any claim the Guarantor may have against the Company or any holder or otherwise, and shall remain in full force and effect without regard to, and shall not be released, discharged or in any way affected by, any circumstance or condition whatsoever (whether or not the Guarantor shall have any knowledge or notice thereof), including, without limitation: (a) any amendment to, modification of, supplement to or restatement of the Notes, the Note Purchase Agreement or any other instrument referred to therein (it being agreed that the obligations of the Guarantor hereunder shall apply to the Notes, the Note Purchase Agreement or any such other instrument as so amended, modified, supplemented or restated) or any assignment or transfer of any thereof or of any interest therein, or any furnishing, acceptance or release of any security for the Notes; (b) any waiver, consent, extension, indulgence or other action or inaction under or in respect of the Notes, the Note Purchase Agreement or any other instrument referred to therein; (c) any bankruptcy, insolvency, arrangement, reorganization, readjustment, composition, liquidation or similar proceeding with respect to the Company or its property; (d) any merger, amalgamation or consolidation of the Guarantor or of the Company into or with any other Person or any sale, lease or transfer of any or all of the assets of the Guarantor or of the Company to any Person; (e) any failure on the part of the Company for any reason to comply with or perform any of the terms of any other agreement with the Guarantor; (f) any failure on the part of any holder to obtain, maintain, register or otherwise perfect any security; or (g) any other event or circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor (whether or not similar to the foregoing), and in any event however material or prejudicial it may be to the Guarantor or to any subrogation, contribution or reimbursement rights the Guarantor may otherwise have. The Guarantor covenants that its obligations hereunder will not be discharged except by indefeasible payment in full in cash of all of the Guaranteed Obligations and all other obligations hereunder.

4

3. WAIVER.

The Guarantor unconditionally waives to the fullest extent permitted by law, (a) notice of acceptance hereof, of any action taken or omitted in reliance hereon and of any default by the Company in the payment of any amounts due under the Notes, the Note Purchase Agreement or any other instrument referred to therein, and of any of the matters referred to in Section 2 hereof, (b) all notices which may be required by statute, rule of law or otherwise to preserve any of the rights of any holder against the Guarantor, including, without limitation, presentment to or demand for payment from the Company or the Guarantor with respect to any Note, notice to the Company or to the Guarantor of default or protest for nonpayment or dishonor and the filing of claims with a court in the event of the bankruptcy of the Company, (c) any right to require any holder to enforce, assert or exercise any right, power or remedy including, without limitation, any right, power or remedy conferred in the Note Purchase Agreement or the Notes, (d) any requirement for diligence on the part of any holder and (e) any other act or omission or thing or delay in doing any other act or thing which might in any manner or to any extent vary the risk of the Guarantor or otherwise operate as a discharge of the Guarantor or in any manner lessen the obligations of the Guarantor hereunder.

4. OBLIGATIONS UNIMPAIRED.

The Guarantor authorizes the holders, without notice or demand to the Guarantor and without affecting its obligations hereunder, from time to time: (a) to renew, compromise, extend, accelerate or otherwise change the time for payment of, all or any part of the Notes, the Note Purchase Agreement or any other instrument referred to therein; (b) to change any of the representations, covenants, events of default or any other terms or conditions of or pertaining to the Notes, the Note Purchase Agreement or any other instrument referred to therein, including, without limitation, decreases or increases in amounts of principal, rates of interest, the Make-Whole Amount or any other obligation; (c) to take and hold security for the payment of the Notes, the Note Purchase Agreement or any other instrument referred to therein, for the performance of this Guarantee Agreement or otherwise for the Indebtedness guaranteed hereby and to exchange, enforce, waive, subordinate and release any such security; (d) to apply any such security and to direct the order or manner of sale thereof as the holders in their sole discretion may determine; (e) to obtain additional or substitute endorsers or guarantors; (f) to exercise or refrain from exercising any rights against the Company and others; and (g) to apply any sums, by whomsoever paid or however realized, to the payment of the Guaranteed Obligations and all other obligations owed hereunder. The holders shall have no obligation to proceed against any additional or substitute endorsers or guarantors or to pursue or exhaust any security provided by the Company, the Guarantor or any other Person or to pursue any other remedy available to the holders.

If an event permitting the acceleration of the maturity of the principal amount of any Notes shall exist and such acceleration shall at such time be prevented or the right of any holder to receive any payment on account of the Guaranteed Obligations shall at such time be delayed or otherwise affected by reason of the pendency against the Company, the Guarantor or any other guarantors of a case or proceeding under a bankruptcy or insolvency law, the Guarantor agrees that, for purposes of this Guarantee Agreement and its obligations hereunder, the maturity of such principal amount shall be deemed to have been accelerated with the same effect as if the holder thereof had accelerated the same in accordance with the terms of the Note Purchase Agreement, and the Guarantor shall forthwith pay such accelerated Guaranteed Obligations.

5

5. SUBROGATION AND SUBORDINATION.

(a) The Guarantor will not exercise any rights which it may have acquired by way of subrogation under this Guarantee Agreement, by any payment made hereunder or otherwise, or accept any payment on account of such subrogation rights, or any rights of reimbursement, contribution or indemnity or any rights or recourse to any security for the Notes or this Guarantee Agreement unless and until all of the Guaranteed Obligations shall have been indefeasibly paid in full in cash.

(b) The Guarantor hereby subordinates the payment of all Indebtedness and other obligations of the Company or any other guarantor of the Guaranteed Obligations owing to the Guarantor, whether now existing or hereafter arising, including, without limitation, all rights and claims described in clause (a) of this Section 5, to the indefeasible payment in full in cash of all of the Guaranteed Obligations. If the Required Holders so request, any such Indebtedness or other obligations shall be enforced and performance received by the Guarantor as trustee for the holders and the proceeds thereof shall be paid over to the holders promptly, in the form received (together with any necessary endorsements) to be applied to the Guaranteed Obligations, whether matured or unmatured, as may be directed by the Required Holders, but without reducing or affecting in any manner the liability of the Guarantor under this Guarantee Agreement.

(c) If any amount or other payment is made to or accepted by the Guarantor in violation of any of the preceding clauses (a) and (b) of this Section 5, such amount shall be deemed to have been paid to the Guarantor for the benefit of, and held in trust for the benefit of, the holders and shall be paid over to the holders promptly, in the form received (together with any necessary endorsements) to be applied to the Guaranteed Obligations, whether matured or unmatured, as may be directed by the Required Holders, but without reducing or affecting in any manner the liability of the Guarantor under this Guarantee Agreement.

(d) The Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by the Note Purchase Agreement and that its agreements set forth in this Guarantee Agreement (including this Section 5) are knowingly made in contemplation of such benefits.

6. REINSTATEMENT OF GUARANTEE.

This Guarantee Agreement shall continue to be effective, or be reinstated, as the case may be, if and to the extent at any time payment, in whole or in part, of any of the sums due to any holder on account of the Guaranteed Obligations is rescinded or must otherwise be restored or returned by a holder upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Company or any other guarantors, or upon or as a result of the appointment of a custodian, receiver, trustee or other officer with similar powers with respect to the Company or any other guarantors or any part of its or their property, or otherwise, all as though such payments had not been made.
