Ladies and Gentlemen:

DONALDSON COMPANY, INC., a Delaware corporation (the“Company”), agrees with you as follows:

SECTION 1. AUTHORIZATION OF NOTES.

Section 1.1. Amount; Establishment of Series. The Company is contemplating the issue and sale of up to $750,000,000 aggregate principal amount of its Senior Notes issuable in series (the“Notes”, such term to include any such Notes issued in substitution therefor pursuant to Section 13 of this Agreement). The Notes shall be substantially in the form set out in Exhibit 1.1-A, with such changes therefrom, if any, as may be approved by the purchasers of such Notes, or series thereof, and the Company. Certain capitalized terms used in this Agreement are defined in Schedule B; references to a “Schedule” or an “Exhibit” are, unless otherwise specified, to a Schedule or an Exhibit attached to this Agreement. The Notes may be issued in one or more series. Each series of Notes, other than the initial series, shall be issued pursuant to a supplement to this Agreement (a“Supplement”) in substantially the form of Exhibit 1.1-B, and shall be subject to the following terms and conditions:


Donaldson Company, Inc.	Note Purchase Agreement


	(a) the designation of each series of Notes shall distinguish the Notes of one series from the Notes of all other series and the designation of each tranche within a series shall distinguish the Notes of one tranche from the Notes of all other tranches;

	(b) the Notes of each series shall rank pari passu with the Notes of all other series and the Company’s other outstanding unsecured Indebtedness that has not been expressly subordinated to any other Indebtedness of the Company;

	(c) each series of Notes shall be dated the date of issue, bear interest at such rate or rates, mature on such date or dates, be subject to such mandatory prepayments on the dates and with the Make-Whole Amounts, if any, as are provided in the Supplement under which such Notes are issued, and shall have such additional or different conditions precedent to closing and such additional or different representations and warranties or other terms and provisions as shall be specified in such Supplement;

	(d) the Subsidiary Guarantor shall deliver an acknowledgement that the Subsidiary Guaranty applies to such additional series of Notes and that the Subsidiary Guaranty continues in full force and effect; and

	(e) except to the extent provided in foregoing clauses (a) through (d), all of the provisions of this Agreement shall apply to the Notes of each series.

The Purchasers of the Series 2014-A Notes need not purchase subsequent series of Notes.

Section 1.2. The Series 2014-A Notes. (a) The Company has authorized, as the initial series of Notes hereunder, the issue and sale of $125,000,000 aggregate principal amount of its 3.72% Senior Notes, Series 2014-A, due March 27, 2024 (the“Series 2014-A Notes” (such term to include any such Notes issued in substitution therefor pursuant to Section 13 of this Agreement)). The Series 2014-A Notes shall be substantially in the form set out in Exhibit 1.2 with such changes therefrom, if any, as may be approved by you and the Company.

(b)Additional Interest. If the Debt to EBITDA Ratio at any time exceeds 3.5 to 1.00, as evidenced by an Officer’s Certificate delivered pursuant to Section 7.2(a), the interest rate payable on each series of Notes shall be increased by 0.50% (the“Additional Interest”), commencing on the first day of the first fiscal quarter following the fiscal quarter in respect of which such Certificate was delivered and continuing until the Company has provided an Officer’s Certificate pursuant to Section 7.2(a) demonstrating that, as of the end of the fiscal quarter in respect of which such Certificate is delivered, the Debt to EBITDA Ratio is not more than 3.5 to 1.0. Following delivery of an Officer’s Certificate demonstrating that the Debt to EBITDA Ratio did not exceed 3.5 to 1.0, the additional 0.50% interest shall cease to accrue or be payable for any fiscal quarter subsequent to the fiscal quarter in respect of which such Certificate is delivered.

(c)Subsidiary Guaranties. All of the outstanding Notes will be guarantied by the Subsidiary Guarantor pursuant to a guaranty substantially in the form set out in Exhibit 1.1-C (the“Subsidiary Guaranty”).

Any Note paid or prepaid in full shall be surrendered to the Company and canceled 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, prepayment or purchase 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. The term“Make-Whole Amount” means with respect to any Series 2014A 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 Series 2014A 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 Series 2014A Note:


	“Called Principal” means, the principal of any Series 2014A 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, with respect to the Called Principal of any Series 2014A Note, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal 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 with respect to such Called Principal.

	“Reinvestment Yield” means, with respect to the Called Principal of any Note, .50% over the yield to maturity implied by the yield(s) reported as of 10:00 a.m. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page PX1” (or such other display as may replace Page PX1) on Bloomberg Financial Markets for the most recently issued actively traded on-the-run U.S. Treasury securities(“Reported”) having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there are no such U.S. Treasury securities Reported having a maturity equal to such Remaining Average Life, then such implied yield to maturity will be determined by

- 20 -


Donaldson Company, Inc.	Note Purchase Agreement


	(a) converting U.S. Treasury bill quotations to bond equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between the yields Reported for the applicable most recently issued actively traded on-the-run U.S. Treasury securities with the maturities (1) closest to and greater than such Remaining Average Life and (2) closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note.

	If such yields are not Reported or the yields Reported as of such time are not ascertainable (including by way of interpolation), then“Reinvestment Yield” means, with respect to the Called Principal of any Note, .50% over the yield to maturity implied by the U.S. Treasury constant maturity yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (or any comparable successor publication) for the U.S. Treasury constant maturity having a term equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there is no such U.S. Treasury constant maturity having a term equal to such Remaining Average Life, such implied yield to maturity will be determined by interpolating linearly between (1) the U.S. Treasury constant maturity so reported with the term closest to and greater than such Remaining Average Life and (2) the U.S. Treasury constant maturity so reported with the term closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note.

	“Remaining Average Life” means, with respect to any Called Principal, the number of years 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 with respect to such Called Principal by (b) the number of years, computed on the basis of a 360-day year composed of twelve 30-day months and calculated to two decimal places, that will elapse between the Settlement Date with respect to such Called Principal 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 8.4 or Section 12.1.

	“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.

presentment, demand, protest or further notice, all of which are hereby waived.

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.

Each such new Note shall be payable to such Person as such holder may request and shall be substantially in the form of Note established for such series. Each such new Note shall be dated and bear interest from the date to which interest shall have been paid on the surrendered Note or dated the date of the surrendered Note if no interest shall have been paid thereon.

	(b) in the case of mutilation, upon surrender and cancellation thereof,

the Company at its own expense shall execute and deliver, in lieu thereof, a new Note of the same series, dated and bearing interest from the date to which interest shall have been paid on such lost, stolen, destroyed or mutilated Note or dated the date of such lost, stolen, destroyed or mutilated Note if no interest shall have been paid thereon.

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.

SUBSIDIARY GUARANTY

THIS GUARANTY (this“Guaranty”) dated as of March 27, 2014 is made by the undersigned (each, a“Guarantor”), in favor of the holders from time to time of the Notes hereinafter referred to and their respective successors and assigns (collectively, the“Holders” and each individually, a“Holder”).

WITNESSETH:

WHEREAS, Donaldson Company, Inc. (the“Company”) entered into a Note Purchase Agreement dated as of March 27, 2014 (the Note Purchase Agreement as it may hereafter be amended, supplemented, restated or otherwise modified from time to time in accordance with its terms, the“Note Purchase Agreement”);

WHEREAS, the Note Purchase Agreement provides for the issuance by the Company of up to $750,000,000 aggregate principal amount of Notes (as defined in the Note Purchase Agreement), of which the Company concurrently with the delivery by the Guarantors of this Guaranty, is issuing $125,000,000 aggregate principal amount of Series 2014‑A Notes;

WHEREAS, the Company owns, directly or indirectly, all of the issued and outstanding capital stock or partnership interests of each Guarantor and, by virtue of such ownership and otherwise, each Guarantor will derive substantial benefits from the purchase by the Holders of the Company’s Notes;

WHEREAS, it is a condition precedent to the obligation of the Holders to purchase the Notes that each Guarantor shall have executed and delivered this Guaranty to the Holders; and

WHEREAS, each Guarantor desires to execute and deliver this Guaranty to satisfy the conditions described in the preceding paragraph;

NOW, THEREFORE, in consideration of the premises and other benefits to each Guarantor, and of the purchase of the Company’s Notes by the Holders, and for other good and valuable consideration, the receipt and sufficiency of which are acknowledged, each Guarantor makes this Guaranty as follows:


SECTION 1. DEFINITIONS.

Any capitalized terms not otherwise herein defined shall have the meanings attributed to them in the Note Purchase Agreement.


SECTION 2. GUARANTY.

Each Guarantor, jointly and severally with each other Guarantor, unconditionally and irrevocably guarantees to the Holders the due, prompt and complete payment by the Company of

EXHIBIT 1.1-C
(to Note Purchase Agreement)


Donaldson Company, Inc.	Note Purchase Agreement

the principal of, Make-Whole Amount, if any, and interest on, and each other amount due under, the Notes or the Note Purchase Agreement, when and as the same shall become due and payable (whether at stated maturity or by required or optional prepayment or by declaration or otherwise) in accordance with the terms of the Notes and the Note Purchase Agreement (the Notes and the Note Purchase Agreement being sometimes hereinafter collectively referred to as the“Note Documents” and the amounts payable by the Company under the Note Documents, and all other monetary obligations of the Company thereunder (including reasonable attorneys’ fees and expenses), being sometimes collectively hereinafter referred to as the“Obligations”). This Guaranty is a guaranty of payment and not just of collectibility and is in no way conditioned or contingent upon any attempt to collect from the Company or upon any other event, contingency or circumstance whatsoever. If for any reason whatsoever the Company shall fail or be unable duly, punctually and fully to pay such amounts as and when the same shall become due and payable, each Guarantor, without demand, presentment, protest or notice of any kind, will forthwith pay or cause to be paid such amounts to the Holders under the terms of such Note Documents, in lawful money of the United States, at the place specified in the Note Purchase Agreement, or perform or comply with the same or cause the same to be performed or complied with, together with interest (to the extent provided for under such Note Documents) on any amount due and owing from the Company. Each Guarantor, promptly after demand, will pay to the Holders the reasonable costs and expenses of collecting such amounts or otherwise enforcing this Guaranty, including, without limitation, the reasonable fees and expenses of counsel. Notwithstanding the foregoing, the right of recovery against each Guarantor under this Guaranty is limited to the extent it is judicially determined with respect to any Guarantor that entering into this Guaranty would violate Section 548 of the United States Bankruptcy Code or any comparable provisions of any state law, in which case such Guarantor shall be liable under this Guaranty only for amounts aggregating up to the largest amount that would not render such Guarantor’s obligations hereunder subject to avoidance under Section 548 of the United States Bankruptcy Code or any comparable provisions of any state law.


SECTION 3. GUARANTOR’S OBLIGATIONS UNCONDITIONAL.

The obligations of each Guarantor under this Guaranty shall be primary, absolute and unconditional obligations of each Guarantor, shall not be subject to any counterclaim, set-off, deduction, diminution, abatement, recoupment, suspension, deferment, reduction or defense based upon any claim each Guarantor or any other person may have against the Company or any other person, and to the full extent permitted by applicable law 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 each Guarantor or the Company shall have any knowledge or notice thereof), including:


	(a) any termination, amendment or modification of or deletion from or addition or supplement to or other change in any of the Note Documents or any other instrument or agreement applicable to any of the parties to any of the Note Documents;

	(b) any furnishing or acceptance of any security, or any release of any security, for the Obligations, or the failure of any security or the failure of any person to perfect any interest in any collateral;

EXHIBIT 1.1-C-2


Donaldson Company, Inc.	Note Purchase Agreement


	(c) any failure, omission or delay on the part of the Company to conform or comply with any term of any of the Note Documents or any other instrument or agreement referred to in paragraph (a) above, including, without limitation, failure to give notice to any Guarantor of the occurrence of a “Default” or an “Event of Default” under any Note Document;

	(d) any waiver of the payment, performance or observance of any of the obligations, conditions, covenants or agreements contained in any Note Document, or any other waiver, consent, extension, indulgence, compromise, settlement, release or other action or inaction under or in respect of any of the Note Documents or any other instrument or agreement referred to in paragraph (a) above or any obligation or liability of the Company, or any exercise or non-exercise of any right, remedy, power or privilege under or in respect of any such instrument or agreement or any such obligation or liability;

	(e) any failure, omission or delay on the part of any of the Holders to enforce, assert or exercise any right, power or remedy conferred on such Holder in this Guaranty, or any such failure, omission or delay on the part of such Holder in connection with any Note Document, or any other action on the part of such Holder;

	(f) any voluntary or involuntary bankruptcy, insolvency, reorganization, arrangement, readjustment, assignment for the benefit of creditors, composition, receivership, conservatorship, custodianship, liquidation, marshaling of assets and liabilities or similar proceedings with respect to the Company, any Guarantor or to any other person or any of their respective properties or creditors, or any action taken by any trustee or receiver or by any court in any such proceeding;

	(g) any discharge, termination, cancellation, frustration, irregularity, invalidity or unenforceability, in whole or in part, of any of the Note Documents or any other agreement or instrument referred to in paragraph (a) above or any term hereof;

	(h) any merger or consolidation of the Company or any Guarantor into or with any other corporation, or any sale, lease or transfer of any of the assets of the Company or any Guarantor to any other person;

	(i) any change in the ownership of any shares of capital stock of the Company or any change in the corporate relationship between the Company and any Guarantor, or any termination of such relationship;

	(j) any release or discharge, by operation of law, of any other Guarantor from the performance or observance of any obligation, covenant or agreement contained in this Guaranty; or

	(k) any other occurrence, circumstance, happening or event whatsoever, whether similar or dissimilar to the foregoing, whether foreseen or unforeseen, and any other circumstance which might otherwise constitute a legal or equitable defense or

EXHIBIT 1.1-C-3


Donaldson Company, Inc.	Note Purchase Agreement


	discharge of the liabilities of a guarantor or surety or which might otherwise limit recourse against any Guarantor.


SECTION 4. FULL RECOURSE OBLIGATIONS.

The obligations of each Guarantor set forth herein constitute the full recourse obligations of such Guarantor enforceable against it to the full extent of all its assets and properties.


SECTION 5. WAIVER.

Each Guarantor unconditionally waives, to the extent permitted by applicable law, (a) notice of any of the matters referred to in Section 3, (b) notice to such Guarantor of the incurrence of any of the Obligations, notice to such Guarantor or the Company of any breach or default by such Company with respect to any of the Obligations or any other notice that may be required, by statute, rule of law or otherwise, to preserve any rights of the Holders against such Guarantor, (c) presentment to or demand of payment from the Company or the Guarantor with respect to any amount due under any Note Document or protest for nonpayment or dishonor, (d) any right to the enforcement, assertion or exercise by any of the Holders of any right, power, privilege or remedy conferred in the Note Purchase Agreement or any other Note Document or otherwise, (e) any requirement of diligence on the part of any of the Holders, (f) any requirement to exhaust any remedies or to mitigate the damages resulting from any default under any Note Document, (g) any notice of any sale, transfer or other disposition by any of the Holders of any right, title to or interest in the Note Purchase Agreement or in any other Note Document and (h) any other circumstance whatsoever which might otherwise constitute a legal or equitable discharge, release or defense of a guarantor or surety or which might otherwise limit recourse against such Guarantor.


SECTION 6. SUBROGATION, CONTRIBUTION, REIMBURSEMENT OR INDEMNITY.

Until one year and one day after all Obligations have been paid in full, each Guarantor agrees not to take any action pursuant to any rights which may have arisen in connection with this Guaranty to be subrogated to any of the rights (whether contractual, under the United States Bankruptcy Code, as amended, including Section 509 thereof, under common law or otherwise) of any of the Holders against the Company or against any collateral security or guaranty or right of offset held by the Holders for the payment of the Obligations. Until one year and one day after all Obligations have been paid in full, each Guarantor agrees not to take any action pursuant to any contractual, common law, statutory or other rights of reimbursement, contribution, exoneration or indemnity (or any similar right) from or against the Company which may have arisen in connection with this Guaranty. So long as the Obligations remain, if any amount shall be paid by or on behalf of the Company to any Guarantor on account of any of the rights waived in this paragraph, such amount shall be held by such Guarantor in trust, segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to the Holders (duly endorsed by such Guarantor to the Holders, if required), to be applied against the Obligations, whether matured or unmatured, in such order as the Holders may determine.

EXHIBIT 1.1-C-4


Donaldson Company, Inc.	Note Purchase Agreement

The provisions of this paragraph shall survive the term of this Guaranty and the payment in full of the Obligations.


SECTION 7. EFFECT OF BANKRUPTCY PROCEEDINGS,ETC.

This Guaranty shall continue to be effective or be automatically reinstated, as the case may be, if at any time payment, in whole or in part, of any of the sums due to any of the Holders pursuant to the terms of the Note Purchase Agreement or any other Note Document is rescinded or must otherwise be restored or returned by such Holder upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Company or any other person, 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 other person or any substantial part of its property, or otherwise, all as though such payment had not been made. If an event permitting the acceleration of the maturity of the principal amount of the Notes shall at any time have occurred and be continuing, and such acceleration shall at such time be prevented by reason of the pendency against the Company or any other person of a case or proceeding under a bankruptcy or insolvency law, each Guarantor agrees that, for purposes of this Guaranty and its obligations hereunder, the maturity of the principal amount of the Notes and all other Obligations shall be deemed to have been accelerated with the same effect as if any Holder had accelerated the same in accordance with the terms of the Note Purchase Agreement or other applicable Note Document, and such Guarantor shall forthwith pay such principal amount, Make-Whole Amount, if any, and interest thereon and any other amounts guaranteed hereunder without further notice or demand.


SECTION 8. TERM OFAGREEMENT.
