the terms hereof on the Maturity Date specified above or upon earlier
redemption or repayment at the Corporate Trust office of the Trustee in the
Borough of Manhattan, The City of New York, State of New York, or such other
locations as may be provided for pursuant to the Indenture referred to on the

the time of payment shall be legal tender for the payment of public and private
debts, and to pay interest semiannually on each Interest Payment Date in each
year and on the Maturity Date or upon earlier redemption or repayment,
commencing with the first Interest Payment Date next succeeding the Original
Issue Date specified above upon the Face Amount at the Interest Rate or, if a
Base Interest Rate is specified above, at the Base Interest Rate multiplied by
an amount as determined in accordance with the terms hereof from the most
recent date to which interest has been paid or duly provided for, or, if no
interest has been paid or duly provided for, from the Original Issue Date,
until the principal hereof becomes due and payable; provided, however, that any
payment of principal or interest to be made on an Interest Payment Date, on the
Maturity Date, on a date fixed for redemption or on a Repayment Date which is
not a Business Day shall be made on the next succeeding Business Day (as
hereinafter defined) with the same force and effect as if made on the Interest
Payment  Date, on the date fixed for redemption or on the Repayment Date, as
the case may be, and no additional interest shall accrue as a result of such
delayed payment.  For purposes of this Note, "Business Day" means any day,
other than a Saturday or Sunday, that is neither a legal holiday nor a day on
which banking institutions are authorized or required by law or regulation to
close in New York, New York, or if this Note is denominated in a Specified

Interest Payment Date will be paid to the person in whose name this Note (or
one or more predecessor Notes) is registered at the close of business on the
Record Date (whether or not a Business Day) immediately preceding such Interest
Payment Date and interest payable on the Maturity Date or upon earlier
redemption or repayment will be payable to the person to whom principal is
payable, except that, if this Note is issued between a Record Date and the

earlier redemption or repayment will be determined by the rate of exchange
between the Specified Currency and the Indexed Currency.  The holder of this
Note will be entitled to receive principal in an amount exceeding the amount
designated as the Face Amount, if, at the Maturity Date or upon earlier
redemption or repayment, the rate at which the Specified Currency can be

Currency per one unit of the Specified Currency, and will be entitled to
receive principal in an amount less than the Face Amount if, at the Maturity
Date or upon earlier redemption or repayment, the rate at which the Specified
Currency can be exchanged for the Indexed Currency is less than the Base
Exchange Rate.  If a Base Interest Rate is specified above, the interest
payable on each Interest Payment Date will be determined by the Base Interest
Rate and the rate of exchange between the Specified Currency and the Indexed
Currency.  The holder of this Note will be entitled to receive an interest
payment exceeding the amount based on the Face Amount and the Interest Rate if,
on an Interest Payment Date, the rate at which the Specified Currency can be
exchanged for the Indexed Currency is greater than the rate of such exchange
designated above as the Base Exchange Rate, expressed in units of the Indexed
Currency per one unit of the Specified Currency, and will be entitled to
receive an interest payment below the amount based on the Face Amount and the
Interest Rate if, on an Interest Payment Date, the rate at which the Specified
Currency can be exchanged for the Indexed Currency is less than the Base
Exchange Rate.  Payment of principal and interest on this Note will be made, if
at maturity or upon earlier redemption, than on the Maturity Date or the date
fixed for redemption, as applicable, upon surrender of this Note at the
Corporate Trust Office of the Trustee in The City of New York, and if upon
repayment prior to maturity, than on the applicable Repayment Date, provided
that the holder shall have complied with the requirements for repayment set
forth on the reverse hereof.  All such payments shall be made in immediately
available funds, provided that this Note is presented to the Corporate Trust
Office of the Trustee in The City of New York in time for the Trustee to make
such payments in such funds in accordance with its normal procedures.  Any such
payments made in a Specified Currency other than U.S. Dollars shall be made by
wire transfer to an account maintained by the holder, as designated by the
holder by written notice to the Trustee at least 15 calendar days prior to the
date fixed for payment, with a bank located in the country of the Specified
Currency.  Payment of interest on this Note (other than interest paid on the
Maturity Date or upon earlier redemption or repayment) will be made by check
(from an account at a bank outside of the United States if such check is
payable in a Specified Currency other than U.S. Dollars) mailed to the address
of the person entitled thereto appearing on the register for the Notes on the
applicable Record Date.  At the option of the Issuer or a holder of Notes (as
defined on the reverse hereof) in an aggregate principal amount exceeding $5
million or the equivalent in a Specified Currency, payment of interest on this
Note (other than interest paid on the Maturity Date or upon earlier redemption
or repayment) will be made by wire transfer to an account maintained by such
holder with a bank located in the United States for a payment in U.S. Dollars
or with a bank located in the country of the Specified Currency for other
payments, provided that any such holder selecting such option shall have
designated such account by written notice to the Trustee no later than the
Record Date preceding the applicable Interest Payment Date.  Any interest not
punctually paid or duly provided for shall be payable as provided in the
Indenture referred to on the reverse hereof.

         Interest will be computed on the basis of a 360-day year of twelve

This is one of the Debt Securities of the series designated therein referred to
in the within-mentioned Indenture

FIRST UNION NATIONAL BANK, 
as Trustee


By:

Authorized Officer


                           [FORM OF REVERSE OF NOTE]

                        AIR PRODUCTS AND CHEMICALS, INC.

         This Note is one of a duly authorized issue of unsecured debentures,
notes or other evidences of indebtedness of the Issuer (hereinafter called the
"Securities") of the series hereinafter specified, all issued or to be issued
under and pursuant to an indenture dated as of January 10, 1995 (the
"Indenture"), duly executed and delivered by the Issuer to First Union National
Bank (formerly, First Fidelity Bank, National Association), as Trustee (the
"Trustee"), to which Indenture and all indentures supplemental thereto reference
is hereby made for a description of the rights, limitation of rights,
obligations, duties and immunities thereunder of the Trustee, the Issuer and the
holders (the words "holders" or "holder" meaning the registered holders or
registered holder of the Securities).  The Securities may be issued in one or
more series, which different series (and which securities issued within each
series) may be issued in various aggregate principal amounts, may mature at
different times, may bear interest (if any) at different rates, may be subject
to different redemption or repayment provisions (if any), may be subject to
different sinking fund or analogous provisions (if any), may be subject to
different Events of Default (as defined in the Indenture) and may otherwise vary
as in the Indenture provided.  This Note is one of a series designated as
"Medium-Term Notes, Series E, Due from 9 Months to 30 Years from Date of Issue"
(the "Notes") of the Issuer, limited in aggregate principal amount to U.S.
$300,000,000, or the equivalent thereof in the Specified Currency or Currencies.

         In case an Event of Default with respect to the Notes shall have
occurred and be continuing, the principal hereof may be declared, and upon
such declaration shall become, due and payable, in the manner, with the effect
and subject to the conditions provided in the Indenture.

         The Indenture contains provisions permitting the Issuer and the
Trustee, with the consent of the holders of not less than 66 2/3% in aggregate
principal amount of the Securities at the time outstanding (as defined in the
Indenture) of all series to be affected (voting as one class), evidenced as in
the Indenture provided, to execute supplemental indentures adding any
provisions to or changing in any manner or eliminating any of the provisions of
the Indenture or of any supplemental indenture or modifying in any manner the
rights of the holders of the Securities of each such series:  provided,
however, that no such supplemental indenture shall (i) extend the final
maturity of any Security, or reduce the principal amount thereof, or reduce the
rate or extend the time of payment of interest thereon, or reduce any amount
payable on redemption thereof, or reduce the amount of the principal of an
Original Issue Discount Security that would be due and payable upon an
acceleration of the maturity thereof pursuant to Section 5.1 of the Indenture
or the amount thereof provable in bankruptcy pursuant to Section 5.2 of the
Indenture, or impair or affect the right of any Securityholder to institute
suit for the payment thereof or the right of repayment, if any, at the option
of the Securityholder without the consent of the holder of each Security so
affected, or (ii) reduce the aforesaid percentage of Securities of any series,
the consent of the holders of which is required for any such supplemental
indenture, without the consent of the holder of each Security so affected.  Any
such consent or waiver by the holder of this Note (unless revoked as provided
in the Indenture) shall be conclusive and binding upon such


                                       4
   5

holder and upon all future holders and owners of this Note and any Notes which
may be issued in exchange or substitution herefor, irrespective of whether or
not any notation thereof is made upon this Note or such other Notes.

         No reference herein to the Indenture and no provision of this Note or
of the Indenture shall alter or impair the obligation of the Issuer, which is
absolute and unconditional, to pay the principal of and any premium and interest
on this Note at the place, at the respective times, at the rate and in the coin,
currency or currency unit herein prescribed unless in accordance with Section
10.1(c) or Section 10.2 of the Indenture the Issuer shall have irrevocably
deposited or caused to be deposited in trust with the Trustee funds in cash
and/or U.S. Government Obligations and/or Foreign Government Securities (each as
defined in the Indenture) as will be sufficient to pay interest due or to become
due on the Notes to, and to pay the principal and any premium due on the Notes
upon, the Maturity Date or upon earlier redemption or repayment.

         The Issuer shall be deemed to have paid the principal of, premium, if
any, and interest on the Notes when the same shall have become due and payable
if in accordance with Section 10.1(c) or Section 10.2(A) the Issuer shall have
irrevocably deposited or caused to be deposited in trust with the Trustee funds
in cash and/or U.S. Government Obligations and/or Foreign Government Securities
(each as defined in the Indenture) as will be sufficient to pay interest due or
to become due on the Notes to, and to pay the principal and any premium due on
the Notes upon, the Maturity Date or upon earlier redemption or repayment the
outstanding Notes.

         The Notes are issuable in fully registered form without coupons in the
minimum denominations of U.S. $100,000 or the equivalent thereof in the
Specified Currency, and in integral multiples of U.S. $1,000 in excess thereof
or 10,000 units of the Specified Currency.

         If an Initial Redemption Date is specified on the face hereof, this
Note may be redeemed at the option of the Issuer, as a whole or from time to
time in part, on any date on or after such Initial Redemption Date and prior to
maturity, upon mailing a notice of such redemption not less than 30 nor more
than 60 days prior to the date fixed for redemption to the holders of the Notes
to be redeemed at their last registered addresses, all as further provided in
the Indenture, at the Optional Redemption Prices, if any, specified on the face
hereof (expressed in percentages of the principal amount) together in each case
with accrued interest to the date fixed for redemption.

         If a Repayment Date is specified or Repayment Dates are specified on
the face hereof, this Note will be repayable at the option of the holder, in
whole or from time to time in part, on such Repayment Date or Repayment Dates
at 100% of the portion of the principal amount to be repaid, together with
interest accrued on such portion to the Repayment Date on which repayment is
sought.  In order for this Note to be repaid, the Issuer must receive at the
Corporate Trust Office of the Trustee in the Borough of Manhattan, The City of
New York, during the period from and including the first day of the Repayment
Option Period for the applicable Repayment Date to and including the close of
business on the last day of such Repayment Option Period (or if such day is not
a business day, the next succeeding business day):  (i) this Note with the form
below entitled "Option to Elect Repayment" duly completed, or (ii) a telegram,
telex, facsimile transmission or letter from a member of a national securities
exchange, or the National Association of Securities Dealers, Inc., or a
commercial bank or a trust company in the United States of America, dated no
later than the last day of such Repayment Option Period (or if such day is not
a business day, the next succeeding business day) setting forth the name of the
holder of the Note, the principal amount of the Note, the portion of the
principal amount of the Note to be repaid, a statement that the option to elect
repayment in being exercised thereby and a guarantee that the Note to be repaid
in whole or in part (with the form entitled "Option to Elect Repayment" on the
reverse of the Note duly completed) will be received at the Corporate Trust
Office of the Trustee in the Borough of Manhattan, The City of New York, no
later the five business days after the date of such telegram, telex, facsimile
transmission or letter and such Note and form duly completed must be
received at the Corporate Trust Office in the Borough of Manhattan, The City of
New York, by such fifth business day.  Effective exercise of any repayment
option by the holder of any Note shall be irrevocable.  No transfer or exchange
of any Note (or, in the event that any Note is to be repaid in part, such
portion of the Note to be repaid) will be permitted after exercise of a 
repayment option.  A repayment option may be exercised by the holder of a Note
for less than the entire principal amount of the Note, provided that the 
principal amount which is to be repaid is equal to $1,000 or any integral 
multiple thereof for Notes denominated in U.S Dollars or 10,000 units of the 
Specified Currency or any integral multiple thereof for Notes denominated in a
Specified Currency other than U.S. Dollars.  All question as to the validity, 
eligibility (including time of receipt) and acceptance of any Note for 
repayment will be determined by


                                       5

the Issuer, whose determination will be final, binding and non-appealable.  For
purposes of this provision, "business day" means any day other than Saturday
and Sunday or a legal holiday or any day on which banking institutions in New
York, New York are authorized or required by law or regulation to close.

         Upon due presentment for registration of transfer of this Note at the
Corporate Trust Office of the Trustee or at such other office or agency as is
designated by the Issuer in the Borough of Manhattan, The City of New York, a
new Note or Notes of authorized denominations for an equal aggregate principal
amount and like tenor will be issued to the transferee in exchange therefor,
subject to the limitations provided in the Indenture, without charge except for
any tax or other governmental charge imposed in connection therewith; provided,
however, that if this Note is a Global Note (as specified on the face hereof),
this Note is exchangeable only if (x) the Depositary notifies the Issuer that
it is unwilling or unable to continue as Depositary for this Note or if at any
time the Depositary ceases to be in good standing under the Securities Exchange
Act of 1934, as amended, or other applicable statutes or regulations, and the
Issuer does not appoint a successor Depositary within 90 days after the Issuer
receives such notice or becomes aware of such ineligibility, or (y) the Issuer
in its sole discretion determines that this Note shall be exchanged for
certified Notes in definitive form, provided that the definitive Notes so
issued in exchange for this Note shall be in authorized denominations and be of
like aggregate principal amount and tenor and terms as the portion of this Note
to be exchanged.

         Unless otherwise specified on the face hereof, principal of this Note
will be payable by the Issuer in the Specified Currency  (except as set forth
herein) at the Maturity Date in an amount equal to the Face Amount plus or
minus an amount determined by the Determination Agent by reference to the
difference between the Base Exchange Rate and the rate at which the Specified
Currency can be exchanged for the Indexed Currency as determined on the second
Exchange Rate Day (the "Determination Date") prior to the Maturity Date by the
Determination Agent based upon the arithmetic mean of the open market spot
offer quotations for the Indexed Currency obtained by the Determination Agent
from the Reference Dealers in The City of New York at 11:00 a.m., New York City
time, on the Determination Date, for an amount of the Indexed Currency equal to
the Face Amount multiplied by the Base Exchange rate, for settlement on the
Maturity Date (such rate of exchange, as so determined and expressed in units
of the Indexed Currency per one unit of Specified Currency, is hereafter
referred to as the "Spot Rate").  If such quotations from the Reference Dealers
are not available on the Determination Date due to circumstances beyond the
control of the Issuer or the Determination Agent, the Spot Rate will be
determined on the basis of the most recently available quotations from the
Reference Dealers.  If any of the Reference Dealers shall be unwilling or
unable to provide the requested quotations, such other major money center bank
or banks in The City of New York as shall be selected by the Issuer, in
consultation with the Determination Agent, shall act as Reference Dealer or
Reference Dealers in replacement therefor.  In the absence of manifest error,
the determination by the Determination Agent of the Spot Rate and the principal
amount of this Note payable at the Maturity Date shall be final and binding on
the Issuer and the holder of this Note.

         Unless otherwise specified on the face hereof, the formulae to be used
by the Determination Agent to determine the principal amount payable at the
Maturity Date will be as follows:  If the Spot Rate exceeds or equals the Base
Exchange Rate, the principal amount payable at the Maturity Date shall equal:

       Face Amount +  (Face Amount   x    Spot Rate - Base Exchange Rate)
                                          ------------------------------
                                                     Spot Rate.

If the Base Exchange Rate exceeds the Spot Rate, the principal amount payable
at the Maturity Date (which shall, in no event, be less than zero) shall equal:

      Face Amount  -  (Face Amount   x    Base Exchange Rate - Spot Rate)
                                          ------------------------------
                                                     Spot Rate.

If the formulae set forth above are applicable hereto, the maximum principal
amount payable at the Maturity Date in respect hereof would be an amount equal
to twice the Face Amount and the minimum principal amount payable would be
zero.  Unless otherwise specified above, the term "Exchange Rate Day" shall
mean any day which is a





                                       6
   7
Business Day in The City of New York and (i) if the Specified Currency or
Indexed Currency is any currency or currency unit other than the U.S. Dollar or
the ECU, a Business Day in the principal financial center of the country of such
Specified Currency or Indexed Currency or (ii) in the case of the ECU, a day
which is not a non-ECU clearing day as determined by the ECU Banking Association
in Paris.

         Unless otherwise specified on the face hereof, on the basis of the
aforesaid determination by the Determination Agent and the formulae and
limitations set forth above, (i) if the Base Exchange Rate equals the Spot Rate,
then the principal amount of this Note payable at the Maturity Date will be
equal to the Face Amount; (ii) if the Spot Rate exceeds the Base Exchange Rate,
then the principal amount so payable will be greater than the Face Amount hereof
up to an amount equal to twice the Face Amount hereof; (iii) if the Spot Rate is
less than the Base Exchange Rate but is greater than one-half of the Base
Exchange Rate, then the principal amount so payable will be less than the Face
Amount hereof; and (iv) if the Spot Rate is less than or equal to one-half of
the Base Exchange Rate, then the Spot Rate will be deemed to be one-half of the
Base Exchange Rate and no principal amount in respect of this Note will be
payable at the Maturity Date. In the event of any redemption or repayment, the
term "Maturity Date" used above also refers to the redemption date or Repayment
Date, if applicable.

         Unless a Base Interest Rate is specified on the face hereof, interest
will be payable on the Face Amount at the Interest Rate. In the event that a
Base Interest Rate is specified on the face hereof, interest shall be payable on
each Interest Payment Date at a rate per annum equal to the Base Interest Rate
multiplied by an Interest Index Factor. The "Interest Index Factor" shall be an
amount determined by the Determination Agent by reference to the following
formula:

                               Interest Spot Rate
                               ------------------
                               Base Exchange Rate

where "Interest Spot Rate" is (i) if at an Interest Payment Date, the rate at
which the Specified Currency can be exchanged for the Indexed Currency, as
determined on the second Exchange Rate Day prior to such Interest Payment Date
(the "Interest Determination Date") by the Determination Agent, on such Interest
Determination Date, (ii) if at the Maturity Date, the Spot Rate. The amount of
interest determined by the Determination Agent to be payable on any Interest
Payment Date and at the Maturity Date in respect of the Securities will be
payable to the holders thereof in the manner set forth herein. In the absence of
manifest error, the determination by the Determination Agent of the Interest
Index Factor, the Interest Spot Rate on each Interest Payment Date, the interest
payments payable and the Spot Rate at the Maturity Date on the Securities shall
be final and binding on the Issuer and the holders of such Securities.

         If "yes" is specified under "U.S. Dollar Payments Option" on the face
hereof, the registered holder of this Note shall be entitled to receive payments
in U.S. Dollars at the Exchange Rate determined as set forth in the Indenture by
notifying the Trustee at the time and in the manner described therein. Costs, if
any, associated with the conversion of the Specified Currency into U.S. Dollars
shall be borne by such holder through deduction from payments required to be
made to such holder of this Note.

         The Issuer will pay any administrative costs imposed by banks in
connection with making payments on this Note by wire transfer, but any tax,
assessment or governmental charge imposed upon payments will be borne by the
holder hereof.

         The Issuer, the Trustee and any agent of the Issuer or the Trustee may
deem and treat the registered holder hereof as the absolute owner of this Note
(whether or not this Note shall be overdue and notwithstanding any notation of
ownership or other writing hereon) for the purpose of receiving payment of or on
account of the principal hereof and premium, if any, and subject to the
provisions on the face hereof, interest hereon, and for all other purposes, and
neither the Issuer nor the Trustee nor any agent of the Issuer or the Trustee
shall be affected by any notice to the contrary.

         No recourse under or upon any obligation, covenant or agreement
contained in the Indenture or in any Note, or because of any indebtedness
evidenced thereby, shall be had against any incorporator, stockholder, officer
or director, as such, of the Issuer or of any successor, either directly or
through the Issuer or any successor, under any 

                                       7

rule of law, statute or constitutional provision or by the enforcement of any
assessment or by any legal or equitable proceeding or otherwise, all such
liability being expressly waived and released by the acceptance hereof and as
part of the consideration for the Issuer hereof.

         Undefined terms used herein which are defined in the Indenture shall
have the respective meanings assigned thereto in the Indenture.
