                            As of December 22, 1994


To the Holder Identified on
the Signature Page at the
End of this Agreement

Ladies and Gentlemen:

     The undersigned, Kaneb Pipe Line Operating Partnership, L.P., a Delaware
limited partnership ("KPOP"), StanTrans, Inc., a Delaware corporation ("STI"),
Kaneb Pipe Line Partners, L.P., a Delaware limited partnership (the
"Partnership"), Support Terminal Services, Inc., a Delaware corporation ("STS"),
and Support Terminals Operating Partnership, L.P., a Delaware limited
partnership ("STOP") hereby agree with you as follows:

     SECTION 1.  THE NOTES AND NOTE AGREEMENTS.
                 ----------------------------- 

     1.1  Series A Notes.  (a) KPOP has duly authorized the issue to the
          --------------                                                
institutional purchasers named on Schedule 1 hereto of KPOP's First Mortgage
Notes due seven years from the date of issuance (the "Series A Final Maturity
Date") in the aggregate principal amount of $27,000,000 to be dated the date of
issuance, to mature on the Series A Final Maturity Date and to be substantially
in the form set forth in Exhibit A hereto, with only such revisions, deletions
and amendments as shall be acceptable to you and the other purchasers of Series
A Notes under the Note Agreements.  The term "Note Agreements" as used herein
refers collectively to this Note Purchase Agreement (this "Agreement") and to
the other Note Purchase Agreements of even date herewith with the various
institutional purchasers named on Schedules 1 and 2 hereto.  The term "Series A
Notes" as used herein refers collectively to the Series A Notes delivered
pursuant to the provisions of this Agreement and the other Note Agreements, and
also to each Series A Note delivered in substitution or exchange for or in lieu
of any such Series A Note.  KPOP hereby represents and warrants that
concurrently herewith it is entering into each of the other Note Agreements in a
form identical hereto except for the signature of the purchaser thereunder at
the end thereof.

     (b)  The unpaid principal amount of the Series A Notes shall bear interest
at the Series A Contract Rate from the date of

                                       1

 
issuance thereof until such unpaid principal amount shall have become due and
payable.  Any principal amount of the Series A Notes and any Applicable Premium
Amount, as the case may be, not paid when due, and (to the extent permitted by
law) any due and unpaid interest accrued thereon, shall bear interest at the
Series A Overdue Rate for the period that the same is overdue.  The Series A
Overdue Rate (herein so called) is equal to the greater of (i) two percent per
annum (2.0%) plus the Series A Contract Rate, and (ii) two percent per annum
(2.0%) plus the Prime Rate; provided that the Series A Overdue Rate shall in no
event exceed the maximum rate permitted by applicable law.  Interest at the
Series A Contract Rate and the Series A Overdue Rate shall be computed on the
basis of a 360-day year of twelve 30-day months.  Interest at the Series A
Overdue Rate shall, to the extent permitted by law, be compounded monthly.
Interest at the Series A Contract Rate shall be payable semi-annually as it
accrues on the sixth month and annual anniversary date of the Series A Closing
Date of each year (or if any such date shall not be a Business Day, the
immediately following Business Day), beginning on the sixth month anniversary
date of the Series A Closing Date and continuing regularly thereafter until the
Series A Notes are paid in full.  Interest at the Series A Overdue Rate shall be
payable upon demand and, whether or not demand is made, on the last day of each
calendar month.  All interest on the Series A Notes, if not already due and
payable, shall be due and payable on the Series A Final Maturity Date.

     (c)  Subject to the terms and conditions of this Agreement, KPOP will sell
to you, and you will purchase from KPOP, on or before January 30, 1995, or such
other date agreed to by you and KPOP (the "Series A Closing Date"), a duly
executed Series A Note dated the Series A Closing Date in the principal amount
set forth opposite your name on Schedule 1, registered in your name, at the
purchase price of 100% of the principal amount thereof.  Delivery of the Series
A Note so to be purchased by you shall be made on the Series A Closing Date at
the offices of Thompson & Knight, P.C., your special counsel, at 1700 Pacific
Avenue, Suite 3300, Dallas, Texas 75201.  Such delivery shall be made against
payment to KPOP of the purchase price for such Series A Note by wire transfer of
immediately available funds in such amount to the account of KPOP at Texas
Commerce Bank, ABA No. 111001150, Account No. 0880-5043997.

     1.2  Series B Notes.  (a) STI has duly authorized the issue to the
          --------------                                               
institutional purchasers named on Schedule 2 hereto of STI's 8.05% First
Mortgage Notes due December 22, 2001 (the "Series B Final Maturity Date") in the
aggregate principal amount of $33,000,000 to be dated the date of issuance, to
mature on the Series B Final Maturity Date and to be substantially in the form
set forth in Exhibit B hereto, with only such revisions, deletions and
amendments as shall be acceptable to you and the other purchasers of Series B
Notes under the Note Agreements.  The term "Series B Notes" as used herein
refers collectively to the Series B Notes delivered pursuant to the provisions
of this

                                       2

 
Agreement and the other Note Agreements, and also to each Series B Note
delivered in substitution or exchange for or in lieu of any such Series B Note.
The term "Notes" as used herein refers collectively to the Series A Notes and
the Series B Notes delivered pursuant to the provisions of this Agreement and
the other Note Agreements, and also to each such Note delivered in substitution
or exchange for or in lieu of any such Note.  STI hereby represents and warrants
that concurrently herewith it is entering into each of the other Note Agreements
in a form identical hereto except for the signature of the purchaser thereunder
at the end thereof.

     (b)  The unpaid principal amount of the Series B Notes shall bear interest
at the rate of 8.05% per annum (the "Series B Contract Rate") from the date of

semi-annually as it accrues on the 22nd dayof  June and December of each year
(or if any such date shall not be a Business Day, the immediately following
Business Day), beginning June 22, 1995 and continuing regularly thereafter until
the Series B Notes are paid in full.  Interest at the Series B Overdue Rate
shall be payable upon demand and, whether or not demand is made, on the last day
of each calendar month.  All interest on the Series B Notes, if not already due
and payable, shall be due and payable on the Series B Final Maturity Date.

     (c)  Subject to the terms and conditions of this Agreement, STI will sell
to you, and you will purchase from STI, on December 22, 1994, or such other date

your name on Schedule 2, registered in your name, at the purchase price of 100%
of the principal amount thereof. Delivery of the Series B Note so to be
purchased by you shall be made on the Series B Closing Date at the offices of

     (a)  keep all of its insurable properties owned by it insured against all
risks usually insured against by Persons operating like properties in the
localities where the properties are located, all in amounts sufficient to
prevent such KPP Company or Subsidiary, as the case may be, from becoming a

amounts not less than the amounts set forth on Schedule 11 hereto or if greater,
the amounts which would be maintained by a prudent company in the same industry

situated and in compliance with any applicable laws; provided, however, such
insurance shall at a minimum be in such

                                      24

                                                                      ----------
Debt": (i) such Debt is permitted to be incurred by Section 8.1(c) at the time

such Debt is incurred, (ii) such Debt is permitted to be incurred pursuant to
the terms of each document or instrument governing other Debt of any of the KPP
Companies or any of their Subsidiaries (or a written consent given thereunder),
(iii) such Debt is permitted

                                      45

 
to be secured on a pari passu basis with all other Debt which is secured by the
Collateral pursuant to the terms of each document or instrument governing such
Debt that is secured by the Collateral (or a written consent given thereunder),
(iv) the initial holders of such Debt are Financial Institutions, (v) such Debt
is not guarantied in any manner by any Person and is not secured by any Lien
unless any such guaranty or Lien shall concurrently benefit and secure all Notes
on a pari passu basis, (vi) any consent or approval of any governmental or
public body or authority which is required for the incurrence of such Debt has

certificate shall have been given not less than 30 days prior to the incurrence
of such Debt and shall contain representations, warranties and covenants (in
form and substance approved by the Trustee) that such Debt complies with each of

the Notes exceeds $60,000,000 or the amount of loans, letters of credit or
commitments to make loans or issue letters of credit under the Bank Debt
Documents exceeds $15,000,000 (exclusive of the amount of premium, interest,
expenses, fees, indemnifications and similar amounts that may be incurred in
respect of such amount), such excess principal amount or excess loans, letters
of credit or commitments shall not be treated as Funded Obligations under the
Intercreditor Agreement unless the same shall be Qualifying Debt.  As used in
this Section 10.4, "Financial Institution" shall mean a commercial bank

company or commercial finance company organized under the laws of any State of
the United States, in each case with capital and surplus in excess of
$100,000,000 at the time it shall become a creditor hereunder, or a separate
account administered by such an insurance company.

     (b)  The Trustee shall be authorized to execute amendments or supplements
to the Security Documents reasonably acceptable to the Trustee and the KPP
Companies to provide for the securing of Qualifying Debt on a pari passu basis
with the Notes, subject to and on the conditions that (i) the KPP Companies and
the holder of the Qualifying Debt shall have complied with such conditions as
the Trustee may reasonable require to assure that such Debt is Qualifying Debt
on the date so secured and (ii) the holders of such Qualifying Debt shall have
executed a written agreement agreeing to be bound by all of the terms and
conditions of the Intercreditor Agreement in the form attached thereto as
Exhibit B. Notwithstanding anything to the contrary contained in this Agreement,
any Note Purchase Document or Bank Debt Document, the Intercreditor Agreement
shall at all times provide that, to the extent (i) the Liens upon the Collateral
securing any such Qualifying Debt are or become subject or subordinate to any
claims or Liens of any other Person to which the Notes are not similarly subject
or subordinate or (ii) the Qualifying Debt, or

                                      46

 
the Liens upon the Collateral securing the Qualifying Debt, shall become subject
or subordinate to claims of any other Person or defenses of any of the KPP
Companies or any other Person (including without limitation avoidability by a
trustee in any bankruptcy or insolvency proceeding) to which any of the Notes
are not subject (each an "Intervening Claim"), any amount which must be applied
against such Intervening Claim shall be deducted from the amount allocable to
such Qualifying Debt by the Trustee or any Holder pursuant to the provisions of
the Intercreditor Agreement.

     (k)  any representation or warranty by or on behalf of the KPP Companies in
the Note Agreements, the Notes, any other Loan Document or in any certificate or

then (i) upon the occurrence of any Event of Default described in subsections
(f), (g) or (h) of this section with respect to either KPP or STI (each a
"Bankruptcy Default"), all of the Notes shall automatically become immediately
due and payable; (ii) upon the occurrence with respect to any Note of any Event
of Default described in subsection (a) or (b), the Holder of any Note may at any
time during its continuance, by written notice to the KPP Companies, declare its
Note to be due and payable, whereupon such Note shall forthwith mature and
become due and payable; or (iii) upon the occurrence of any other Event of
Default, the Requisite Holders may at any time during its continuance, by
written notice to the KPP Companies, declare all of the Notes to be due and
payable, whereupon in each case all of the Notes shall forthwith mature and
become due and payable.

     The amount payable upon the occurrence of a Bankruptcy Default shall be, to
the extent permitted by law, the entire unpaid principal amount of the Notes,
together with interest accrued thereon, and such amount shall be payable without
presentment, demand, protest or other requirement of any kind, all of which are
expressly waived by the KPP Companies and their Subsidiaries.  The amount
payable upon an acceleration based on

                                      49

 
any other Event of Default shall be, to the extent permitted by law, the entire
unpaid principal amount of the Notes so accelerated, the interest accrued
thereon to the date of acceleration, and the Applicable Premium Amount, and such
amount shall be payable without presentment, demand, protest or further notice,
all of which are expressly waived by the KPP Companies.

     On any date on which the Requisite Holders give written notice to the KPP
Companies declaring all of the Notes to be due and payable pursuant to Section
11.1(iii), the Requisite Holders shall give written notice to the KPP Companies
and to all the other Holders of the amount of the Applicable Premium Amount of
the Notes so accelerated, which notice shall set forth in reasonable detail the
computation thereof.  Within five Business Days after Requisite Holders receive
notice that any other Holder has given written notice to the KPP Companies
declaring its Note to be due and payable pursuant to Section 11.1(ii), the
Holder of such Note shall give written notice to the KPP Companies of the amount
of the Applicable Premium Amount of the Note so accelerated, which notice shall
set forth in reasonable detail the computation thereof, and the KPP Companies
shall provide written notice of such Applicable Premium Amount to the other
Holders.  The Applicable Premium Amount set forth in any such notice shall be
binding on the KPP Companies and the Holders absent manifest error.

     If, at any time after any or all of the Notes shall have been declared due
and payable pursuant to this Section 11.1 and before any judgment or decree for
the payment of monies due shall have been obtained or entered, the KPP Companies
shall pay in full the principal, interest and Applicable Premium Amount which
shall have become due and payable in respect of the Notes otherwise than by such
declaration, with interest upon all such overdue principal and the Applicable
Premium Amount and (to the extent that payment of such interest is enforceable
under applicable law) upon overdue interest at the Series A Overdue Rate and the
Series B Overdue Rate, as applicable, to the date of such payment, and an
additional amount sufficient to reimburse the Holders for their costs and
expenses incurred in connection with any such declaration, and the KPP Companies
shall remedy every other Event of Default, then the Requisite Holders, by
written notice to the KPP Companies, may (but shall have no obligation to)
rescind and annul such declaration and its consequences; but no such rescission
or annulment shall extend to or shall affect any subsequent default or shall
impair any right consequent thereon.

     11.2  Suits for Enforcement.  Subject to the exercise by Trustee of its
           ---------------------                                            
powers under the Security Documents, in case any one or more of the Events of
Default specified in Section 11.1 shall occur and be continuing, the Holder of
each Note may proceed to protect and enforce its rights by suit in equity,
action at law or by other appropriate proceeding, whether for the specific
performance (to the extent permitted by law) of any

                                      50

 
covenant or agreement contained in such Note or the Note Agreements or any other
Loan Document or in aid of the exercise of any power granted therein, or may
proceed to enforce the payment of such Note or to enforce any other legal or
equitable right of such Holder.  If any Holder of a Note shall demand payment
thereof or take any action in respect of a Default or an Event of Default, the
KPP Companies will forthwith give written notice to the other Holders of Notes,
specifying such action and the nature of the Default or Event of Default.  The
notice to each Holder shall also set forth the respective names and addresses
of, and principal amounts of the Notes held by, the other Holders.

     In case of a Default or Event of Default, the KPP Companies will pay to
each Holder such further amount as shall be sufficient to cover such Holder's
costs and expenses of collection and enforcement, including attorneys' fees, to
the extent provided in Section 13.2.

     11.3  Remedies Cumulative.  No remedy herein conferred upon any Holder is
           -------------------                                                
intended to be exclusive of any other remedy, and each and every such remedy
shall be cumulative and shall be in addition to every other remedy given
hereunder or now or hereafter existing at law or in equity or by statute or
otherwise.

     11.4  Remedies Not Waived.  No course of dealing or unwritten agreement or
           -------------------                                                 
practice between the KPP Companies and any Holder shall operate as a waiver of
any right of any Holder and no delay on the part of any Holder in exercising any
right shall so operate.

     11.5  Indemnity.  Each KPP Company and their Subsidiaries, jointly and
           ---------                                                       
severally, agrees to indemnify and reimburse each Holder, upon demand, against
and for any and all liabilities, obligations, claims, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements
(including reasonable fees of attorneys, accountants, experts and advisors) of
any kind or nature whatsoever (in this section collectively called "liabilities
and costs") which to any extent (in whole or in part) may be imposed on,
incurred by, or asserted against such Holder growing out of, resulting from, or
in any other way associated with the Note Agreements, the Notes, the other Note
Purchase Documents or the transactions and events (including the enforcement or
defense thereof) at any time associated herewith or therewith or contemplated
herein or therein.  THE FOREGOING INDEMNIFICATION AND REIMBURSEMENT OBLIGATIONS
OF THE KPP COMPANIES SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND COSTS ARE
IN ANY WAY OR TO ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR
OMISSION OF ANY KIND BY SUCH HOLDER, PROVIDED THAT:

          (a)  Except as provided in the following subsection (b), no Holder
     shall be entitled under this section to

                                      51

 
     receive indemnification for (i) that portion of any final judgment for
     liabilities and costs which portion, determined in accordance with
     principles of comparative fault, is based upon a finding that such Holder
     has been grossly negligent or has engaged in willful misconduct, or (ii)
     the liabilities and costs representing that portion of any out-of-court
     settlement by a Holder which has been allocated by the parties to such
     settlement to a claim that such Holder has been grossly negligent or has
     engaged in willful misconduct.

          (b)  Each Holder shall be entitled under this section to receive
     indemnification and reimbursement for any liabilities and costs arising
     from a final judgment in favor of an Outside Party to the effect that such
     Holder is somehow legally responsible (due to a theory of imputed
     negligence or otherwise) for the negligence or other acts or omissions of
     any KPP Company or any of their Affiliates.

          (c)  Each KPP Company shall (upon demand as the same are incurred)
     indemnify and reimburse each Holder for all costs, expenses, and
     disbursements of any kind or nature whatsoever (including reasonable fees
     of attorneys, accountants, experts and advisors) which are incurred by such
     Holder in defending against any claim or allegation that such Holder has
     been grossly negligent or has engaged in willful misconduct.  Each Holder
     agrees to reimburse the KPP Companies for amounts paid to such Holder under
     this Section 11.5(c) upon the determination in a final judgment that such
     Holder has been grossly negligent or has engaged in willful misconduct.

          (d)  No Holder shall, without the consent of the KPP Companies, which
     consent shall not be unreasonably withheld, enter into any out-of-court
     settlement of any claim for liabilities and costs if the KPP Companies
     would be obligated under this section to indemnify such Holder for amounts
     paid by such Holder under such settlement.  The KPP Companies will,
     however, consent to any settlement proposed by such Holder which is
     reasonable in light of the then existing circumstances.

As used in this section: the term "Holder" shall refer not only to each Person
who is the Holder of any Note at the time in question but also to any former
Holder of such Note (or of any predecessor Note) and to each director, officer,
agent, attorney, employee, representative and affiliate of such present or
former Holder, and the term "Outside Party" shall refer, with respect to any
Holder, to any Person other than such Holder, its owners, and the insurance or
other regulatory authorities which exercise jurisdiction over its ability to
purchase promissory notes and engage in transactions of the kind contemplated
herein.

                                      52

 
     SECTION 12.  CONSENTS, WAIVERS AND AMENDMENTS.  Any term, covenant,
                  --------------------------------                      
agreement or condition of the Notes or the Note Agreements or any other Loan
Document may, with the consent of the KPP Companies, be amended or compliance
therewith may be waived (either generally or in a particular instance and either
retroactively or prospectively), but any such amendment or waiver must be made
in writing by one or more instruments signed by the Requisite Holders; provided
that:

     (a)  no such amendment or waiver shall, without the consent of all Holders,

          (1)  change the maturity of the principal of, or any installment of
     interest on, any of the Notes, or reduce the principal amount thereof or
     the interest thereon, or subordinate or otherwise modify the terms of
     payment of the principal thereof or interest or premium thereon including
     any extension of the time for, or change in the application or priority of,
     any such payment, or

          (2)  give to any Note any preference over any other Note, or

          (3)  reduce the percentage of the principal amount of Notes the
     Holders of which are required to approve any such amendment or effectuate
     any such waiver, or

          (4)  except as provided in Section 10.4, amend any Guaranty or amend
     any other Security Document where the effect of such amendment releases any
     Collateral or adversely affects the perfection or priority of any Lien on
     the Collateral, or

          (5)  amend or waive any of the provisions of this Section 12,

          (6)  amend any of the provisions of the Intercreditor Agreement, and

     (b)  no such waiver shall extend to or affect any obligation not expressly
waived or impair any right consequent thereon.

     The KPP Companies will not, directly or indirectly, solicit, request or
negotiate for or with respect to any proposed waiver or amendment of any of the
provisions of this Agreement, the Notes or other Note Purchase Documents unless
each Holder (irrespective of the amount of Notes then owned by it) shall
concurrently be informed thereof by the KPP Companies and shall be afforded the
opportunity of considering the same and shall be supplied by the KPP Companies
with sufficient information, including but not limited to the making of updated
representations and warranties comparable in scope to those set forth in Section
2, to enable it to make an informed decision with respect thereto.  The KPP
Companies will not, directly or

                                      53

 
indirectly, pay or cause to be paid any remuneration, whether by way of
supplemental or additional interest, fee or otherwise, to any Holder as
consideration for or as an inducement to the entering into by any Holder of any
waiver or amendment of any of the terms and provisions of this Agreement or
other Loan Document unless such remuneration is concurrently paid, on the same
terms, ratably to each Holder of then outstanding Notes.  The KPP Companies will
not in connection with any solicitation, request or negotiation of any waiver or
amendment, directly or indirectly, prepay or offer to prepay (and shall
represent that they do not contemplate prepaying within the next twelve months)
any series that would not be prepaid ratably with the Notes of the other series,
and any prepayment made by the KPP Companies during the twelve months
immediately following such waiver or amendment, must be pro rata between the
Series A Notes and the Series B Notes, except for such difference in the offer
price between Series A Notes and Series B Notes which reflects only the
differences in the interest rates thereon and payment dates or maturity date
thereof and is reasonably determined.

     Subject to the last sentence of this paragraph, any amendment or waiver
pursuant to this Section 12 shall apply equally to all Holders and shall be
binding upon them, upon each further Holder of any Note and upon the KPP
Companies whether or not such Note shall have been marked to indicate such
amendment or waiver.  No such amendment or waiver shall extend to or affect any
obligation not expressly amended or waived or impair any right related thereto.
For purposes of determining whether the Holders of the requisite aggregate
principal amount of Notes at any time have agreed or consented to any amendment
or waiver pursuant to the provisions of this Section 12, any Notes held by any
KPP Company, any of their Subsidiaries or any Affiliate shall not be deemed
outstanding.  Any consent made by a Holder that has transferred or has agreed to
transfer its Notes to a KPP Company, any of their Subsidiaries or any Affiliate
thereof and has provided or has agreed to provide such written consent as a
condition to such transfer shall be void and of no force and effect except
solely as to such Holder, and any amendments effected or waivers granted or to
be effected or granted that would not have been or would not be so effected or
granted but for such consent (and the consent of all other Holders that were
acquired under the same or similar conditions) shall be void and of no force and
effect retroactive to the date such amendment or waiver initially took or takes
effect, except solely as to such Holder.

     SECTION 13.  SPECIAL RIGHTS OF PURCHASER.
                  --------------------------- 

     13.1  Method of Payment; Indemnity.  Anything contained in the Notes to the
           ----------------------------                                         
contrary notwithstanding, in the case of each Note held by you, KPOP and STI

principal thereof and the Applicable Premium Amount (if any) and interest
thereon by wire transfer in immediately available funds not later than

Schedule 2, as appropriate), on the date each such payment is due pursuant to
the terms hereof and the terms of the Notes, to the account specified under your
name on Schedule 1 or Schedule 2, as appropriate (or in such other manner or at
such other address or account in the United States as you may from time to time
designate to the KPP Companies in writing), each such payment being accompanied
by the reference number specified on Schedule 1 or Schedule 2, as appropriate,
and by such other information as is necessary to identify the source and
application thereof, and all without any presentment or surrender of such Note
and without any notation of such payment being made thereon.  You agree that in
the event you shall sell or transfer such Note you will notify the KPP Companies
of that fact and will prior to the delivery of such Note make, or cause to be
made, a notation thereon of all principal, if any, theretofore paid on such Note
and of the date to which interest has been paid on such Note.  The KPP Companies
agree that, in the event that any Note held by you is lost, stolen or destroyed
and application is made, pursuant to the provisions of Section 14.3, for the
execution and delivery of a new Note in lieu thereof, an unsecured indemnity
agreement signed by you shall constitute indemnity satisfactory to the KPP
Companies.

     13.2  Expenses.  Whether or not the transactions contemplated herein shall
           --------                                                            
be consummated, the KPP Companies shall pay all of your and the Trustee's
expenses, including out-of-pocket expenses, arising in connection therewith,
including the fees and disbursements of your special counsel and Trustee's
special counsel for all services incident to the preparation and negotiation of
the Note Agreements, the Notes, the other Note Purchase Documents and all other
documents and instruments delivered in connection therewith.   The KPP Companies
shall also pay all compensation to the Trustee and any and all costs, expenses
or disbursements (including reasonable fees of attorneys, accountants, experts
and advisers) of any kind or nature whatsoever which is incurred by the Trustee
resulting from or in any other way associated with any of the Collateral, the
Note Purchase Documents and the transactions and events (including the
enforcement or defense thereof) at any time associated therewith or contemplated
therein.  The KPP Companies shall also pay, and save you harmless from, any and
all liabilities with respect to the assignment of a private placement number
from Standard and Poor's CUSIP Service Bureau, trustee's fees and expenses,
environmental assessment charges, title charges, survey costs, filing,
registration and recording fees, mortgage recording taxes, stamp and other
taxes, duties, imposts, assessments and other charges which may be payable or
deemed to be payable in connection with the execution and delivery of this Note
Agreement, the Notes and the other Note Purchase Documents.  The KPP Companies
agree, to the extent permitted by applicable law, to pay and indemnify you
against any costs and expenses, including reasonable attorneys' and accountants'
fees, incurred by you, any subsequent Holder or the Trustee in evaluating (in

                                      55

 
connection with any controversy or potential controversy) and enforcing,
exercising or defending any rights or remedies under this Agreement, the Notes
and the other Note Purchase Documents or in responding to any subpoena or other
legal process issued in connection with this Agreement or the transactions
contemplated hereby or by reason of your or any subsequent Holder's having
acquired any Note, including without limitation, costs and expenses incurred in
any bankruptcy case.  Without limiting the foregoing, to the extent permitted by
applicable law, the KPP Companies also will pay the reasonable fees, expenses
and disbursements of an investment bank or other firm acting as adviser (which
fees, expenses and disbursements may include, without limitation, reasonable
legal and accounting fees) to the Holders of the Notes following the occurrence
and during the continuance of a Default or an Event of Default or in connection
with any such amendment or waiver proposed in connection with any potential
Default or Event of Default or any workout, restructuring or similar
negotiations relating to this Agreement, the Notes and the other Note Purchase
Documents or any other Holder.  The obligations of the KPP Companies under this
Section 13.2 shall survive the transfer of any Note or portion thereof or
interest therein by you or any subsequent Holder and the payment of any Note.

     SECTION 14.  REGISTRATION, TRANSFER OR EXCHANGE OF NOTES.
                  ------------------------------------------- 

     14.1  Note Register.  The KPP Companies shall keep at their office or
           -------------                                                  
agency maintained as provided in Section 7.1 a register in which the KPP
Companies shall provide for the registration of Notes and for the registration
of transfer and exchange of Notes.

     14.2  Surrender for Transfer.  The Holder of each Note at its option may
           ----------------------                                            
either in person or by duly authorized attorney surrender the same for
registration of transfer or exchange at such office or agency of the KPP
Companies and, without expense to such Holder (other than for transfer taxes, if
any), receive in exchange therefor a Note or Notes, each in the face amount of
at least $900,000 (or if the outstanding principal amount of a Note being so
transferred or exchanged is less than $900,000 at such time, then in the face
amount of amount then outstanding), dated as of the date to which interest has
been paid on the surrendered Note, and registered in the name of such Person or
Persons as may be designated by such Holder, for the same aggregate principal
amount as the then unpaid principal amount of such surrendered Note.  Every Note
presented or surrendered for registration of transfer or exchange shall be
accompanied by a written instrument of transfer in the form of Exhibit D to this
Agreement, duly executed by the Holder of such Note or his attorney duly
authorized in writing.  Every Note so made and delivered in exchange for any
surrendered Note shall in all other respects be in the same form and have the
same terms as such surrendered Note.  No transfer or exchange of any Note shall
be valid unless made in the foregoing manner at such office or agency.

                                      56

 
     14.3  Loss, Theft, Destruction or Mutilation of Notes.  Upon receipt of
           -----------------------------------------------                  
evidence reasonably satisfactory to the KPP Companies of the loss, theft,
destruction or mutilation of any Note, and, in the case of any such loss, theft
or destruction, upon receipt of indemnity or instrument reasonably satisfactory
to the KPP Companies which may include unsecured corporate obligations in the
case of any institutional investor, or in the case of any such mutilation, upon
surrender and cancellation of the mutilated Note, the KPP Companies will make
and deliver, in lieu of such lost, stolen, destroyed or mutilated Note, a new
Note of like tenor and unpaid principal amount, dated as of the date to which
interest has been paid on such earlier Note.

     14.4  Holders.  Provided that the KPP Companies have complied with their
           -------                                                           
obligation to register any transfer or exchange of a Note under Section 14.2,
the KPP Companies may deem and treat the Holder of each Note as the owner and
holder of such Note for the purpose of receiving payment of principal and
interest on such Note and for all other purposes whatsoever, whether or not such
Note shall be overdue.

survive the issuance and delivery of the Notes and your purchase thereof and
payment therefor and shall continue in full force and effect so long as any Note
is outstanding and unpaid.  In addition, the KPP Companies' obligations under

covenants, agreements, representations and warranties in this Agreement
contained by or on behalf of the KPP Companies, or by or on behalf of you, shall
