ARTICLE 3

BENEFITS

Section 3.1 Eligibility and Vesting. Subject to Sections 5.1 and 6.2, an Employee shall be entitled to receive benefits under this Plan if such person shall be entitled to receive a benefit under the Salaried Pension Plan. Benefits under this Plan shall be calculated in accordance with Section 3.2 hereof and shall be subject to the limitations herein provided.

Section 3.2 Amount of Benefits. The amount of the benefit to be paid to an Employee or any other person entitled to receive a benefit hereunder shall be equal to the amount of the benefit such person would have received under the Salaried Pension Plan (without regard to the limitations under Sections 401(a)(17), and 415 of the Internal Revenue Code) if such benefit were calculated using Average Compensation calculated pursuant to Section 3.3 hereof, and then reduced by the amount of the actual benefit payable to such person under the Salaried Pension Plan and further reduced by any amount previously paid under this Plan. For purposes of this Section, if an Employee has a Separation from Service prior to attaining age 55 and is subsequently reemployed by the Company and such reemployment continues at the Employee’s age 55, the benefit such Employee will be entitled to receive at age 55 based on his or her prior Separation from Service shall be calculated pursuant to the provisions of Section 3.4 of the Salaried Pension Plan. The normal form of benefit under Section 4.1 of the Salaried Pension Plan shall be employed as the

7

basis for making computations under this Section 3.2 in order to insure the attaining for such purpose of equivalency between the various forms of benefits provided by the Salaried Pension Plan and this Plan, regardless of whether an optional form of benefit has been selected under Article V of the Salaried Pension Plan and/or under Section 3.6 of this Plan.

Section 3.3 Employee Compensation. For purposes of computing an Employee’s benefit in accordance with Section 3.2 hereof, the Employee’s Average Compensation shall be the monthly average of the Compensation of the Employee for the 36 consecutive months (or total consecutive months if he or she was employed by an Employer for less than 36 months) calculated to include any months while on leave of absence, if such months would be considered in the Average Compensation in the Salaried Pension Plan, in which his Compensation was the highest during the 120 months nearest preceding his Separation from Service (or during the total period of employment if he or she was employed by an Employer less than 120 months). For this purpose, an Employee’s Compensation for any period shall be equal to the sum of (a) his “Compensation” for such period as defined in Article I of the Salaried Pension Plan, provided that no limitation based on Code Section 401(a)(17) shall apply, (b) one hundred percent (100%) of the Employee’s Incentive Compensation allocated to such period in accordance with Section 3.4 hereof and (c) one hundred percent (100%) of the amount of annual salary deferred by the Employee under the Air Products and Chemicals, Inc. Supplementary Savings Plan on or before September 1, 2006 and the Air Products and Chemicals, Inc. Deferred Compensation Plan thereafter, which amount, but for such deferral election, would have been received by the Employee as annual salary during such period.

Section 3.4 Allocation of Incentive Compensation. For the purpose of computing the Employee’s Compensation in accordance with Section 3.3 hereof, all Incentive Compensation shall be allocated to the period for which the

8

Incentive Compensation was awarded to the Employee by the Employer, notwithstanding actual distribution of the Incentive Compensation at a later time. The total dollar value of Incentive Compensation awards shall be allocated in equal amounts to each month of the period for which the award was made.

Section 3.5 Payment of Benefits.

9

Notwithstanding the above, benefits to Employees for whom the Company has purchased annuities from Transamerica Occidental Life Insurance Company to fund their benefit under the Salaried Pension Plan shall be payable under this Plan on the first of the month after the Employee attains age sixty-five (65). Payment of benefits will commence within 90 days of the Employee’s satisfying the conditions therefore (the first day of which shall be the Annuity Starting Date for purposes of Section 409A), and upon the Employee’s proper application therefore or the Plan Administrator’s determination of the Employee’s eligibility to commence benefits according to elections previously filed, except for small benefits as described in Section 3.9(a). The Plan will not be responsible for any delays or the costs or taxes associated with any delays that result from the Employee’s failure to make proper application for benefits or for delays associated with the normal processing of benefit payments. For benefit payments commencing before 1 October 2006, benefits shall be paid in the Primary Form of Benefit as determined in Section 5.2 of the Salaried Pension Plan, unless the Employee shall elect to have an optional form of benefit in accordance with the provisions of Section 3.6A hereof. For benefit payments commencing on or after 1 October 2006, benefits shall be paid in a lump sum form of benefit described in Section 3.6(b) below unless the Employee shall elect to have benefits paid as an annuity in accordance with the provisions of Section 3.7 hereof in which case, the Employee may elect the form of the annuity as described in Sections 5.2(a), (b) and (c) of the Salaried Pension Plan. All payments of benefits shall be subject to Federal income and such other tax withholding as required by applicable law.

10

Section 3.6 Optional Forms of Retirement Benefit.

11

12

In case the above measure is no longer in use or available, the Committee will select a comparable alternative.

If the Employee elects an annuity under section3.6(a)(i) above and does not elect the form of an annuity prior to the Annuity Starting Date, the Employee shall be deemed to have elected Option B as set forth in Section 5.2 of the Salaried Pension Plan, substituting the benefit determined under Section 3.2 above for the benefit determined under Article IV of the Salaried Pension Plan.

Section 3.6A Election of Benefit Form Prior to 1 October 2006.

For Annuity Starting Dates occurring prior to 1 October 2006, the following procedures shall apply for election of optional forms of benefit.

13

Section 3.7 Election of Benefit Form On or After 1 October 2006

For Annuity Starting Dates occurring on or after 1 October 2006, the following procedures shall apply for election of optional forms of benefit.

(iii) An Employee for whom the Company has purchased annuities from Transamerica Occidental Life Insurance Company to fund their benefit under the Salaried Pension Plan.

Section 3.8 Pre-Retirement Spousal Benefits. If an Employee dies prior to his or her Annuity Starting Date, a pre-Retirement spousal benefit shall be payable to the Employee’s surviving spouse, if any, in the same form as that elected by the Employee, commencing the first of the month following the later of the Employee’s death or the date the Employee would have attained (i) age 50, if the Employee was actively employed by the Company at time of death or if the

15

Employee died while performing qualified military service if the Employee is entitled to early retirement benefits under Section 3.2(c), (d), (e) or (f) of the Salaried Pension Plan or Article 3A of this Plan, or (ii) age 55. The amount of the benefit shall be calculated in the same manner as provided in Section 5.7 or 5.10 of the Salaried Pension Plan except substituting the benefit determined under Section 3.2 above for the benefit determined under Article IV of the Salaried Pension Plan.

If a former Key Employee dies after his or her Annuity Starting Date but prior to the delayed payment date of his or her benefit described in Section 3.5(b) above, the Employee’s spouse shall receive a distribution within 90 days of the Employee’s death of the benefit payments that would have been payable to the Employee on and after the Annuity Starting Date had the payment not been delayed, adjusted for the delayed payment.

Section 3.9 Small Benefit Payment Procedures.

16

Section 3.10 Change in Control. Notwithstanding the above provisions of this Article 3, upon a Change in Control, an Employee shall have an immediate, nonforfeitable right to his or her Accrued Benefit under the Plan and shall receive an immediate lump sum payment of such. This payment shall not affect his or her continued eligibility under the Plan; however, his or her Accrued Benefit under the Plan shall be reduced by the amount paid out.

ARTICLE 3A

SPECIAL SUPPLEMENTAL BENEFITS

Notwithstanding any provision of the Plan to the contrary, certain employees of the Employer shall be entitled to receive a special supplemental benefit under the Plan in accordance with the following provisions:

17

ARTICLE 4

ADMINISTRATION

Section 4.1 Plan Administration and Interpretation. The Plan shall be administered by the Plan Administrator. The Plan Administrator shall have full power and authority to administer the Plan and interpret the Plan in a manner which is as consistent with the interpretations of similar provisions in the Salaried Pension Plan as the context reasonably permits. The Plan Administrator’s powers shall include, by way of illustration and not limitation, the discretionary authority and power to construe and interpret the Plan provisions, decide all questions of eligibility for benefits, and determine the amount, time, and manner of payments of any benefits and to authorize the payment of benefits hereunder, except to the extent such powers have been given to the Committee pursuant to Section 4.2 below or otherwise. The Plan Administrator may appoint one or more individuals or committees to assist him in carrying out his duties and responsibilities under the Plan and may adopt rules and regulations for the administration of the Plan and alter, amend, or revoke any rules or regulations so adopted. The decisions of the Plan Administrator or his delegates shall be final and binding on the Company, the Employers, the Employees, and their beneficiaries.

18

Section 4.2 Claim and Appeal Procedure.

In the event the claim is wholly or partially denied, the Plan Administrator’s written notification shall state the specific reason or reasons for the denial, include specific references to pertinent Plan provisions on which the denial is based, provide an explanation of any additional material or information necessary for the Employee or beneficiary to perfect the claim and a statement of why such material or information is necessary, and set forth the procedure by which the Employee or beneficiary may appeal the denial of the claim. If the claim has not been granted and notice is not furnished within the time period specified in the preceding paragraph, the claim shall be deemed denied for the purpose of proceeding to appeal in accordance with paragraph (b) below.

19

ARTICLE 5

FUNDING

Section 5.1 Benefits Unfunded. The Plan shall be unfunded. Neither an Employer, the Board, nor the Plan Administrator shall be required by the

20

terms of the Plan to segregate any assets in connection with the Plan. Neither an Employer, the Board nor the Plan Administrator shall be deemed to be a trustee of any amounts to be paid under the Plan. Any liability to any person with respect to benefits payable under the Plan shall be only a claim against the general assets of the Employer. No such liability shall be deemed to be secured by any pledge or any other encumbrance on any specific property of the Employer.

Section 5.2 Non-Qualified Plan. The Plan will not be qualified under the Code and the Company and the Employers shall not be required to qualify the Plan.

Section 5.3 ERISA. The Plan is intended to constitute an unfunded plan maintained primarily for the purpose of providing deferred compensation to a select group of management or highly compensated employees of the Employer which qualifies for the exclusion provided for in Sections 201(2), 301(a)(3) and 401(a)(1) of ERISA. In the event that any regulatory body should determine that the Plan does not qualify for such exclusion, then the Company may retroactively revise the eligibility criteria under the Plan so that this Plan may qualify for the exclusion or take such other action as is deemed necessary, and the Company and the Employers shall have no liability to those individuals who had been eligible for benefits under the Plan prior to such revision or action except to the extent of the individual’s Accrued Benefit as of the effective date of such action.

ARTICLE 6

AMENDMENT AND TERMINATION

Section 6.1 Amendment and Termination. While the Company intends to maintain this Plan in conjunction with the Salaried Pension Plan for so

21

long as necessary or desirable, the Company reserves the right at any time to amend, suspend, and/or terminate this Plan, in whole or part. Action to terminate the Plan may be taken on behalf of the Company only by the Board, by its resolutions duly adopted. Any other action referred to in this subsection and not determined by the Company’s general counsel to be in contravention of law may be taken on behalf of the Company by the Board or the Chairman of the Board or his delegate by a resolution, certificate, new or revised Plan text, or other writing; provided that, only the Board may approve a Plan amendment which (A) would materially increase aggregate accrued benefits under, materially change the benefit formula provided by, or materially increase the cost of the Plan so long as persons designated by the Board as “Executive Officers” for purposes of the U.S. Securities laws participate in the Plan; or (B) would freeze benefit accruals, materially reduce benefit accruals, or otherwise materially change the benefits under the Plan; or (C) would constitute the exercise of power or function assigned to the Finance Committee of the Board, the Plan Administrator, or the Committee. The Chairman may delegate the authority described in the preceding sentence in writing. Notwithstanding the above no such amendment, termination or suspension shall reduce the benefits payable to or accrued by an Employee as of the date of such amendment, suspension or termination, except as provided in Section 5.3. If this Plan is terminated, no new benefits shall be accrued hereunder; and all benefits previously accrued shall be payable at such times as otherwise provided herein.

Section 6.2 Contractual Obligations. Notwithstanding Section 5.1 hereof, each Employer hereby makes a contractual commitment to pay the benefits theretofore accrued in respect of each Employee of such Employer under the Plan to the extent it is financially capable of meeting such obligations from its general assets, and at such times as such benefits are payable under the terms hereof.

22

Section 6.3 No Employment Rights. Nothing contained in the Plan shall be construed as a contract of employment between an Employer and any Employee, or as a right of any Employee to be continued in the employment of an Employer, or as a limitation on the right of an Employer to discharge any of its Employees, with or without cause. Specifically, no rights are created under the Plan with respect to continued employment. It is understood that each Employee is employed at the will of the respective Employer and the Employee and in accord with all statutory provisions.

ARTICLE 7

GENERAL PROVISIONS

Section 7.1 Non-alienation of Benefits. Except as may be required by law, no benefit payable under the Plan is subject in any manner to anticipation, alienation, sale, transfer, assignment, garnishment, pledge, encumbrance, or charge whether voluntary or involuntary, including in respect of liability of an Employee or his beneficiary for alimony or other payments for the support of a spouse, former spouse, child, or other dependent, prior to actually being received by the Employee or beneficiary under the Plan, and any attempt to anticipate, alienate, sell, transfer, assign, garnish, pledge, encumber, or charge the same shall be void. No such benefits will in any manner be liable for or subject to the debts, liabilities, engagements, or torts of any Employee or other person entitled to receive the same and if such person is adjudicated bankrupt or attempts to anticipate, assign, or pledge any benefits, the Plan Administrator shall have the authority to cause the same or any part thereof then payable to be held or applied to or for the benefit of such Employee, his spouse, children or other dependents, or any of them, in such manner and in such proportion as the Plan Administrator may deem proper.

Section 7.2 Minor or Incompetent. If the Plan Administrator determines that any Employee or beneficiary entitled to payments under the Plan

23

is a minor or incompetent by reason of physical or mental disability, it may, in its sole discretion, cause all payments thereafter becoming due to such person to be made to any other person for his benefit, without responsibility to follow application of amounts so paid. Payments made pursuant to this provision shall completely discharge the Company, the Employers, the Plan, the Board, and the Plan Administrator from all further obligations with respect to benefits under the Plan.

Section 7.3 Payee Unknown. If the Plan Administrator has any doubt as to the proper beneficiary to receive payments hereunder, the Plan Administrator shall have the right to withhold such payments until the matter is finally adjudicated. However, any payment made in good faith shall fully discharge the Plan Administrator, the Company, the Employers, and the Board from all further obligations with respect to that payment.

Section 7.4 Illegal or Invalid Provision. In case any provision of the Plan shall be held illegal or invalid for any reason, such illegal or invalid provision shall not affect the remaining parts of the Plan, but the Plan shall be construed and enforced without regard to such illegal or invalid provision.

Section 7.5 Governing Law and Headings. The provisions of the Plan shall be construed, administered, and governed in accordance with the laws of the Commonwealth of Pennsylvania, including its statute of limitation provisions, to the extent such laws are not preempted by ERISA or other applicable Federal law. Titles of Articles and Sections of the Plan are for convenience of reference only and are not to be taken into account when construing and interpreting the provisions of the Plan.

Section 7.6 Liability Limitation. No liability shall attach to or be incurred by the Plan Administrator or any officer or director of the Company or an Employer under or by reason of the terms, conditions, and provisions contained

24

in the Plan, or for the acts or decisions taken or made thereunder or in connection therewith; and as a condition precedent to the receipt of benefits hereunder, such liability, if any, is expressly waived and released by the Employee and by any and all persons claiming under or through the Employee or any other person. Such waiver and release shall be conclusively evidenced by any act of participation in or the acceptance of benefits under the Plan.

Section 7.7 Notices. Except as otherwise specified, any notice to the Plan Administrator, the Company, or an Employer which shall be or may be given under the Plan shall be in writing and shall be sent by registered or certified mail to the Plan Administrator. Notice to an Employee shall be sent to the address shown on the Company’s or the Employer’s records. Any party may, from time to time, change the address to which notices shall be mailed by giving written notice of such new address.

Section 7.8 Entire Agreement. Except as may be provided in an individual severance agreement between the Company or other Employer and an Employee, this Plan document shall constitute the entire agreement between the Company or other Employer and the Employee with respect to the benefits promised hereunder and no other agreements or representations with respect to such benefits, oral or otherwise, express or implied, shall be binding on the Company or other Employer.

Section 7.9 Binding Effect. All obligations for amounts not yet paid under the Plan shall survive any merger, consolidation, or sale of substantially all of the Company’s or an Employer’s assets to any entity, and be the liability of the successor to the merger or consolidation or purchaser of assets, unless otherwise agreed to in writing by the parties thereto.

25

IN WITNESS WHEREOF, the Company, intending to be legally bound hereby, has caused the Plan to be adopted and approved by the execution of its duly authorized officers as of the      day of              2014.
