     consummation of the transactions contemplated hereby and thereby, nor the
     fulfillment of or compliance with the terms and conditions of any thereof
     conflicts with or results in a material breach of the terms, conditions or
     provisions of or will constitute a default under any restriction or any
     agreement or instrument to which any is now a party or by which any is

     therefor, wherein an unfavorable decision, ruling or finding would
     materially adversely affect the transactions contemplated by this Agreement
     or which would adversely affect, in any way, the validity or enforceability

     (o)  No Person (or any Related Person within the meaning of Section
     144(a)(3) of the Code) who was a substantial user of the Project, within
     the meaning of Treas. Reg. Sec. 1.103-8(a)(5)(iv), at any time during the
     five (5) year period immediately preceding the date hereof, and who will
     receive, directly or indirectly, Bond Proceeds of the Bonds in an amount
     equal to five per centum (5%) or more of the face amount of the Bonds in

     Project or a Related Person at any time during the five (5) year period
     beginning on the date of issuance of the Bonds;

     (p)  The Project was not acquired or placed in service by the Borrower
     (determined in accordance with the provisions of Section 103 of the Code
     and applicable regulations thereunder) more than one (1) year prior to the
     date of issuance of the Bonds;

     (q)  Subsequent to thirty-one (31) days prior to the date hereof, the
     Borrower or any Related Person (or group of related persons which includes
     the Borrower) has not guarantied, arranged, participated in, assisted with,
     borrowed the proceeds of, or leased facilities financed by obligations
     issued under Section 103 of the Code by any state or local governmental
     unit or any constituted authority empowered to issue obligations by or on
     behalf of any state or local governmental unit other than the Issuer.
     During the period commencing on the date of issuance of the Bonds and
     ending thirty-one (31) days thereafter, there will be no obligations issued
     under Section 103 of the Code which are guarantied by the Borrower or any
     Related Person (or group of related persons which includes the Borrower) or
     which are issued with the assistance or participation of, or by arrangement
     with the Borrower or any Related Person (or group of related persons which
     includes the Borrower) without the written opinion of Robinson, St. John &
     Wayne, Esqs. or other nationally recognized bond counsel acceptable to
     Robinson, St. John & Wayne, Esqs. to the effect that the issuance of such
     obligation will not adversely affect their opinion as to exemption from
     present Federal income taxes of interest on the Bonds.  Other than the
     Borrower or any Related Person (or group of related persons including the
     Borrower), no person has (i) guarantied, arranged, participated in,
     assisted with the issuance of, or paid any portion of the cost of the

any basis therefor, wherein an unfavorable decision, ruling or finding would
materially adversely affect the transactions contemplated hereby, or which in
any way would materially adversely affect the validity of the Bonds, the
Indenture, the Resolutions, this Loan Agreement, any agreement or instrument to

taxation as set forth herein; and

                         APPLICATION OF BOND PROCEEDS

     Section 5.1.  Agreement to Issue Bonds; Application of Bond Proceeds.
                   ------------------------------------------------------      
In order to provide for the payment of costs of and related to the issuance of
the Bonds and the Costs of the Project incurred to date and hereafter to be
incurred by the Borrower, subject to the provisions of Article IV hereof and
concurrently with the execution and delivery of this Agreement, the Issuer will
initially issue, sell and deliver Bonds in the aggregate original principal
amount of $5,000,000 and deposit the net proceeds thereof to the credit of the
Project Fund, as established and provided in Article VI of the Indenture.  The
Issuer authorizes, and directs the Trustee to make disbursements from the
Project Fund of Bond proceeds from the sale of the Bonds for work performed on
the Project or to reimburse the Borrower for any costs and expenses of the
Project paid by it.  Each disbursement shall constitute a Proper Charge and
shall be disbursed upon delivery to the Trustee of the following:

          (a) a Requisition signed by an authorized Borrower Representative.
     The Requisition Form shall state: (i) the requisition number; (ii) the name
     and address of the Person to whom payment is to be made by the Trustee or,
     if the payment is to be made to the Borrower for a reimbursable advance,
     the name and address of the Person to whom such advance was made together
     with proof of payment by the Borrower; (iii) the amount to be paid; (iv)
     that each obligation for which payment is sought is a Proper Charge against
     the Project Fund, is unpaid or unreimbursed, and has not been the basis of
     any previously paid requisition; (v) if such payment is a reimbursement to
     the Borrower for costs or expenses incurred by reason of work performed or
     supervised by officer's or employees of the Borrower or any of its
     affiliates, that the amount to be paid does not exceed the actual cost
     thereof to the Borrower or any of its affiliates; (vi) that no Event of
     Default has occurred under this Loan Agreement; and (vii) the Borrower has
     received no written notice of any lien, right to lien or attachment upon,
     or other claim affecting the right to receive payment of, any of the moneys
     payable under such Requisition Form to any of the Persons named therein or,
     if any of the foregoing has been received, it has been released or
     discharged or will be released or discharged upon payment of the
     Requisition Form;

          (b) prior to the first disbursement from the Project Fund either (i) a
     certificate of an authorized Borrower Representative stating that, for
     purposes of the Prevailing Wage Provision and the Affirmative Action
     Program, none of the moneys disbursed at any time from the Project Fund
     will be used to pay or reimburse a payment for work done in performance of
     any Construction Contract unless prior thereto there shall be submitted to
     the Trustee an executed Contractor's Certificate and Agreement or (ii) a
     Contractor's Certificate and Agreement executed by the Contractor.
     Nevertheless, prior to the initial disbursement from the Project Fund for
     payment of any Construction Contract, if not theretofore furnished, a
     Contractor's Certificate and Agreement shall be submitted.

                                       11
<PAGE>
 
     There shall be retained in the Project Fund an amount equal to ten per
centum (10%) of each sum requisitioned for payment or reimbursement for payment
of a Construction Contract for purposes of the Affirmative Action Program (a
"holdback"); provided, however, if any such requisitioned sum is for
reimbursement of a payment by the Borrower, which payment itself was for only
ninety per centum (90%) of the payment requested by the Contractor or
Subcontractor pursuant to such Construction Contract, then such requisitioned
sum may be reimbursed without regard to the aforementioned holdback, but the
remaining ten per centum (10%), when requisitioned by the Borrower, shall only
be disbursed upon the holdback conditions hereinafter set forth.  Said holdback
shall be disbursed from the Project Fund upon compliance with the preceding
terms and conditions of this Section and (i) the execution and filing of the
Contractor's Completion Certificate, (ii) the execution and filing of the
Borrower's Completion Certificate and (iii) receipt by the Borrower of a written
notice issued by the Issuer's Office of Affirmative Action that the Contractor
has complied with the requirements of the Affirmative Action Program.

     Nothing contained herein or in any documents and agreements contemplated
hereby or in any other Loan Document shall impose upon the Trustee or the Issuer
any obligation to see to the proper application of such disbursements by the
Borrower or any other recipient thereof, and, in making such disbursements from
the Project Fund, the Trustee may rely on such Requisition Forms and proof
delivered to it.  The Trustee and the Issuer shall be relieved of any liability
with respect to making such disbursements in accordance with the foregoing.

     Thereafter and in the event of the issuance of additional Bonds as provided
in Section 2.19(B) of the Indenture, the Issuer will sell and deliver such Bonds
and deposit the net proceeds thereof to the credit of the Project Fund for
application as set forth above

     Section 5.2.  Projects Undertaking.  The Borrower agrees that it shall
                   --------------------                                        
proceed with due diligence and reasonable dispatch, delays caused by force
majeure, as defined in Section 9.1 hereof, alone excepted, to undertake and
complete the acquisition, construction, installation and equipping of the
Facilities.

     In the event of the issuance of Additional Bonds, as provided in Section
2.19(B) of the Indenture, the Borrower agrees that it shall proceed with due
diligence and reasonable dispatch, delays caused by force majeure alone
excepted, to undertake and complete the next phase of the acquisition,
installation and equipping of the Facilities, as contemplated for the issuance
of the Additional Bonds.

     Section 5.3.  Projects Completion.  Not later than August 1, 1994, or
                   -------------------                                        
upon the completion of the Borrower's Project (the "Completion Date") and the
payment or provision for the payment of all of the Costs thereof, the Borrower
shall cause to be furnished to the Trustee the Borrower's Completion Certificate
signed by an authorized Borrower Representative stating the date of completion
of the Project and that, as of such date, except for amounts retained by the
Trustee at the Borrower's direction for any cost of the Project not then due and
payable or, if due and payable not then paid:  (i) the Project has been
completed; (ii) the cost of all labor, services, materials and supplies used in
the Project have been paid, or will be paid from amounts retained

                                       12
<PAGE>
 
by the Trustee at the Borrower's direction for any cost of the Project not then
due and payable or, if due and payable, not then paid; (iii) the Project
equipment, if any, has been installed to the Borrower's satisfaction, such
Project equipment so installed is suitable and sufficient for the efficient
operation of the Project for the intended purposes and all costs and expenses
incurred in the acquisition and installation of such equipment have been paid,
or will be paid from amounts retained by the Trustee at the Borrower's direction
for any cost of the Project not then due and payable or, if due and payable, not
then paid; (iv) the Project is being operated as an authorized "project" under
the Act and substantially as proposed in the Application; (v) the Borrower has
reviewed the Contractor's Completion Certificate and the Borrower has no
knowledge or information that the representations contained therein are false or
misleading; and (vi) the Borrower has required in all Construction Contracts
that wages paid to workers employed in the performance of Construction Contracts
be paid at a rate not less than the Prevailing Wage Rate.  Notwithstanding the
foregoing, the Borrower's Completion Certificate may state that it is given
without prejudice to any rights against third parties which exist at the date of
the Borrower's Completion Certificate or which may subsequently come into being.
Any amount remaining in the Project Fund thereafter (except for amounts therein
sufficient to cover costs of the Project not then due and payable or not then
paid) shall be transferred by the Trustee to the Principal Account in accordance
with Section 4.01 of the Indenture and shall not be invested at a yield
materially higher than the yield on the Bond

     Section 5.4.  Borrower Required to Pay if Project Fund Insufficient.
                   -----------------------------------------------------      
In the event the moneys in the Project Fund available for payment of the costs
of the Project are not sufficient to pay all costs of the Project in full, the
Borrower agrees to complete the Project and to pay that portion of the cost in
excess of the moneys available therefor in the Project Fund.  The Issuer, the
Bank and the Trustee make no warranty, either express or implied, that the
moneys paid into the Project Fund and available for payment of the costs of the
Project will be sufficient to pay all of such costs.  The Borrower agrees that
if, after disbursement of all the money in the Project Fund available for
payment of costs of the Project, the Borrower should pay any portion of the
costs of the Project pursuant to the provisions of this Section, it shall not be
entitled to any reimbursement therefor from the Issuer, the Bank or the Trustee.

     Section 5.5.  Investment of Moneys.  Any moneys held under the
                   --------------------                                
Indenture as a part of any fund or account, other than the Bond Fund, shall,
subject to Section 4.01(d) of the Indenture, be invested or reinvested by
Trustee, to the extent permitted by law, at the written request (or verbal
request if confirmed in writing) of and as directed by the Borrower
Representative, in Authorized Investments as provided in the Indenture.

     The Trustee may make any and all such investments through departments of
any bank or trust company under common control with the Trustee.  All such
investments shall at all times be a part of the Fund or Account from which the
moneys used to acquire such investments shall have come and all income and
profits on such investments shall be credited to, and losses thereon shall be
charged against, the Earnings Sub-Accounts of such Funds and Accounts.  Such
investments shall be registered in the name of the Trustee, as Trustee under the
Indenture.

     Section 5.6.  Special Arbitrage Covenant.  The Borrower covenants not
                   --------------------------                                 
to cause or direct any moneys on deposit in any fund or account to be used in a
manner which would cause the Bonds to be classified as "arbitrage bonds" within
the meaning of Section 148 of the Code, and the Borrower certifies and covenants
to and for the benefit of the Issuer and the Owners of the Bonds Outstanding
that so long as there are any Bonds Outstanding, moneys on deposit in any Fund
or Account in connection with the Bonds, whether such moneys were derived from
the proceeds of the sale of the Bonds or from any other sources, will not be
used in a manner which will cause the Bonds to be classified as "arbitrage
bonds" within the meaning of Section 148 of the Code.  The event of
classification of the Bonds as "arbitrage bonds" under Section 148 of the Code
shall be treated as a "Determination of Taxability" under Section 6.5 hereof and
shall not constitute a Default by the Borrower.

     In connection herewith and for purposes of insuring compliance with the
provisions of Section 148 of the Code, as the same may from time to time be
amended and the application thereof interpreted, the Borrower acknowledges that
its financial officers, Borrower's Representative and its accountant have read
and are familiar with the requirements of Sections 4.01(d), 4.01(e) and 5.04 of
the Indenture and hereby agrees (i) to timely make or cause to be made the
annual determinations required under Section 4.01(e) of the Indenture, (ii) to
furnish the Trustee such statements and instructions as are required under said
Section 4.01(e), (iii) to timely make or to cause, to be made the determinations
required under said Section 4.01(d) (1) of the Indenture, (iv) to furnish to the
Trustee such forms, statements, instructions and funds, if any, as are required
under subparagraph (i), (ii) and (iii) of said subsection 4.01(d)(1), (v) as
required, to secure and furnish to the Trustee a statement of its Accountant as
provided for under Section 4.01(d)(4) of the Indenture, (vi) to keep and retain
such records as are required under Section 4.01(d)(6) thereof.  In addition, the
Borrower shall keep or cause to be kept such records as shall enable it to
fulfill its obligations and responsibilities under this Section and Section 148
of the Code and shall retain such records for a period of six (6) years
following the final payment of principal on the Bonds.  In further connection
herewith, the Borrower expressly agrees that any failure, for any reason
whatever, of the Trustee to give any notice, determination, report or statement
required or provided for in said Section 4.01(d), shall not cause the Trustee or
the Issuer to comply with the requirements of Section 148 of the Code, and,
further, that the Borrower, shall pay all such costs as may be incurred by the
Trustee in engaging a firm of certified public accountants or other firm having
expertise in the subject matter to make such calculations and prepare such
certifications as are or may be required under said Sections 4.01(d) or 4.01(e)
in the event of the Borrower's failure to cause or secure the same; provided,
however, that this provision shall in no manner be deemed to require such an
engagement by the Trustee in the event of the Borrower's failure to perform all
its obligations under this Section 5.6

          obligation of the Borrower to make any such payment required under
          this clause (iii) shall be reduced by the amount of moneys available
          for such payment described in Section 2.13(A) and (C) of the
          Indenture; and, provided further, that the obligation of the Borrower
          to make the payments required under clauses (i), (ii) and (iii) hereof

provision for payment thereof having been made in

                                      23

accordance with the provisions of the Indenture) (i) the Facilities or any
portion thereof are destroyed (in whole or in part) or damaged by fire or other
casualty or (ii) title to or any interest in, or the temporary use of, the
Facilities or any part thereof shall be taken under the exercise of the power of
eminent domain by any governmental body or by any person, firm or corporation
acting under governmental authority, the Borrower shall be obligated to continue
to pay the amounts specified in Section 6.1 of this Agreement.

     The Issuer, the Trustee and the Borrower will cause the Net Proceeds of any
insurance proceeds or condemnation award resulting from any event described
above involving $100,000 or more per occasion or event to be deposited in a
separate trust fund within the Project Fund held the Trustee.  All such Net
Proceeds so deposited shall be applied in one or more of the following ways as
shall be elected by the Borrower in a written notice to the Issuer and the
Trustee:

     (a)  To the prompt repair, restoration, modification or improvement of the
     Project or the Facilities by the Borrower.  (The Issuer has, in the
     Indenture, authorized and directed the Trustee to make disbursements from
     such separate fund for such purposes or to reimburse the Borrower for costs
     paid by it in connection therewith.) Any balance of the Net Proceeds
     remaining after such work has been completed shall be transferred to the
     Bond Fund to be applied to the reimbursement of the Bank for amounts owing
     under the Credit Agreement and/or otherwise in accordance with Section
     4.01(a) of the Indenture.

     (b)  To the transfer into the Redemption Account of the Bond Fund for
     application for redemption of the Bonds on the next succeeding redemption
     date as specified in a written notice by the Borrower to the Trustee in
     accordance with the Indenture, provided that no part of the Net Proceeds
     may be applied for such redemption unless (1) all of the Bonds are to be
     redeemed in accordance with the Indenture upon termination of this
     Agreement or (2) in the event that less than all of the Bonds are to be
     redeemed, the Borrower shall furnish to the Issuer, the Bank and the
     Trustee, a certificate of Borrower Representative acceptable to the Issuer,
     the Bank and the Trustee stating that (i) the property forming the part of
     the Project and the Facilities that was damaged or destroyed by such
     casualty or was taken by such condemnation proceedings is not essential to
     the use or possession of the Project and the Facilities by the Borrower or
     (ii) the Project and the Facilities has been repaired, restored, modified
     or improved to operate as designated.

     If such Net Proceeds are insufficient to pay in full the cost of any
repair, restoration, modification or improvement referred to in this Section
7.9, the Borrower will nonetheless complete the work and will pay any cost in
excess of the amount of the Net Proceeds held by the Trustee.  The Borrower
agrees that if by reason of any such insufficiency of such Net Proceeds, the
Borrower shall make any payments pursuant to the provisions of this Section, the
Borrower shall not be entitled to any reimbursement therefor from the Issuer,
the Trustee or the Owners of any of the Bonds, nor shall the Borrower be
entitled to any diminution of the amounts payable under Section 6.1 of this
Agreement.

     Section 7.10.  Financial Statements and Information.  (a) The Borrower
                    ------------------------------------                       
will, upon request, furnish to the Issuer and the Trustee copies of the
following financial statements, reports and information: within 120 days after
the close of each fiscal year of the Borrower (a "Fiscal Year"), a balance sheet
as of the end of such Fiscal Year and statements of changes in cash flows,
revenue and expenses and changes in financial position of the Borrower for such
Fiscal Year, each prepared in accordance with generally accepted accounting
principles consistently applied, in reasonable detail and certified by a firm of
independent certified public accountants, together with a statement of the chief
financial officer of the Borrower to the effect that no event which constitutes
a Default under this Agreement has occurred and is continuing or if such an
event has occurred and is continuing a statement specifying the nature and
period of existence thereof.

     (b)  The Borrower shall promptly, from time to time, furnish to the Issuer
and the Trustee such information regarding the business, operations and
financial condition of the Borrower, as the Issuer may reasonably request.

     Section 7.11.  Reorganization or Fundamental Change.  The Borrower
                    ------------------------------------                   
shall not initiate any proceedings to dissolve or liquidate without making prior
provisions for the payment in full of its Indebtedness (as such term is defined
in the Credit Agreement).  The Borrower will not consolidate with, merge into or
permit any other corporation or entity to consolidate with, merge into it,
unless the following conditions are met:

          (i)       the successor formed by or resulting from such consolidation
     or merger (the "Successor Corporation") is a corporation, or similar
     entity, organized under the laws of the United States or any state,
     district or territory of the United States and qualified to do business in
     the State and in such other states as the Borrower conducts business;

          (ii)      the Successor Corporation (if other than the Borrower) shall
     expressly assume in writing the full and faithful performance of the
     duties, obligations and covenants of the Borrower under this Agreement and
     the Borrower's Note, and any and all such other agreements and instruments
     as the Borrower may execute and deliver in connection with any of the
     foregoing (collectively, the "Bond Documents");

          (iii)     both before and immediately after such consolidation or
     merger, neither the Borrower nor the Successor Corporation shall be in
     default in the performance or observance of any duties, obligations or
     covenants of the Borrower under any of the Bond Documents;

          (iv)      the Borrower shall have furnished to the Issuer and the
     Trustee an opinion of counsel experienced in matters relating to tax
     exemption of interest on bonds issued by states and their political
     subdivision, and/or a letter of ruling of the Internal Revenue Service,
     satisfactory to the Issuer and the Trustee, to the effect that the interest
     on the Bonds will not become, by reason of the merger or consolidation,
     includable in the gross income of the recipients thereof for purposes of
     federal income taxation;


                                      25
<PAGE>
 
          (v)     the Borrower shall have furnished to the Issuer and the
     Trustee evidence in the form of financial statements prepared by an
     independent certified public accountant or firm of such accountants showing
     that the net assets of the Successor Corporation are at least equal to the
     net assets of the Borrower prior to such merger or consolidation as shown
     by the last previous audited financial statement of the Borrower prior to
     such merger or consolidation; and

          (vi)    the Successor Corporation shall not be subject to any pending
     or threatened litigation or other contingent liabilities which, in the
     opinion of counsel to the Borrower (which may be rendered in reliance upon
     the opinion of counsel to the Successor Corporation), would result in any
     material adverse change in the financial condition or operations of such
     successor or which might materially adversely affect the obligations
     hereunder or in connection with the transactions contemplated hereby.

     If a merger or consolidation is effected as provided in this Section 7.11,
the provisions of this Section 7.11 shall continue in full force and effect and
no further merger, consolidation, sale or transfer shall be effected except in
accordance with the provisions of this Section 7.11.

     Section 7.12.  Maintenance of Tax-Exempt Status of Bonds.
                    -----------------------------------------     

     (a)  Neither the Borrower nor the Issuer shall use, permit the use of, or
omit to use Gross Proceeds or any other amounts (or any property acquired,
constructed, or improved with Gross Proceeds) in a manner which, if made or
omitted, respectively, would cause interest on any Bond to become includable in
the gross income, as defined in Section 61 of the Code, of the owners thereof
for federal income tax purposes.  Without limiting the generality of the
foregoing, unless and until the Borrower and the Issuer shall have received an
Opinion of Counsel to the effect that failure to comply with such covenant will
not adversely affect any exemption from federal income tax of interest on any
Bond, the Borrower and the Issuer shall comply with each of the specific
covenants in this Section.

     (b)  The Borrower covenants and agrees that at least 95% of the proceeds of
the Bonds actually expended will be used to pay costs of the Project incurred
subsequent to July 2, 1991, (in respect of work performed or items purchased
after such date) which are costs of land or property subject to the allowance
for depreciation provided by Section 167 of the Code and are chargeable to the
capital account of the Borrower for federal income tax purposes or would be so
chargeable either with a proper election by the Borrower under the Code or but
for a proper election by the Borrower under, the Code to deduct such amounts.
For purposes of this paragraph, "proceeds of the Bonds" means the proceeds
derived by the Issuer from the sale of the Bonds plus earnings from the
investment of amounts deposited in the Project Fund.  In the event that proceeds
of the Bonds remain unspent after the completion of the Project, the Borrower
covenants and agrees that all of such unspent proceeds will be used to redeem
the largest portion of the Bonds callable under the terms of the Indenture
without premium or penalty that does not exceed the amount of such unspent
proceeds.  Pending such redemption, the Borrower covenants and agrees that any
such unspent proceeds will be deposited in escrow as soon as possible after the
completion of the Project and invested to produce a yield no greater than the
yield on the Bonds.


                                      26
<PAGE>
 
     (c)  The Borrower covenants and agrees that costs of issuance of the Bonds
financed directly or indirectly from the proceeds of the Bonds shall not, exceed
2% of the proceeds of the Bonds.

     (d)  The Borrower covenants and agrees that the weighted average maturity
of the Bonds will not exceed 120 percent of the average reasonably expected
economic life of the Project, both as calculated pursuant to Section 147(b) of
the Code.

     (e)  The Borrower represents and covenants that, except for the Bonds,
there are no obligations issued by or on behalf of any state, territory, or
possession of the United States, or political subdivision of the foregoing, or
of the District of Columbia which constitute "private activity bonds" within the
meaning of Section 141 of the Code:

          (i)    which are secured by any financial commitment on the part of
     the Borrower or any related person to the Borrower, within the meaning of
     Section 144(a)(3) of the Code, and which were or will be issued within the
     period beginning 60 days prior to the Closing Date and ending 60 days
     thereafter; or

          (ii)   the proceeds of which were or will be used with respect to the
     Project or any other facility using substantial common facilities with the
     Project (e.g., in the same building, enclosed shopping mall, or strip of
     stores, offices, or warehouses), within the meaning of Section 144(a)(9) of
     the Code; or

          (iii)  the proceeds of which are or will be used primarily with
     respect to facilities the principal user of which is or will be the
     Borrower or any related person to the Borrower, within the meaning of
     Section 144 (a) (3) of the Code, and which are located in the Township of
     Ewing, New Jersey or if located outside of the Township of Ewing, New
     Jersey which are contiguous to or integrated with such facilities.

     (f)  The Borrower covenants and agrees that:

          (i)    no proceeds of the Bonds will be used to provide:

                 (A)  any private or commercial golf course, country club,
          massage parlor, tennis club, skating facility (including roller
          skating, skateboard, and ice skating), racquet sports facilities
          (including handball and racquetball), hot tub facility, suntan
          facility, or racetrack, or

                 (B)  any airplane, skybox or other private luxury box, any
          health club facility, any facility primarily used for gambling, or any
          store the principal business of which is the sale of alcoholic
          beverages for consumption off premises,

          (ii)   not more than 5 percent of the proceeds of the Bonds will be
     used directly or indirectly, to provide real property for family units,

                                       27
<PAGE>
 
          (iii)  not more than 25 percent of the proceeds of the Bonds will be
     used to provide a facility the primary purpose of which is (or so long as
     any Bonds remain Outstanding will be):

                 (A)  retail food and beverage services (including all eating
          and drinking places but excluding grocery stores),

                 (B)  automobile sales or services, or

                 (C)  the provision of recreation or entertainment,

          (iv)   less than 25 percent of the proceeds of the Bonds will be used
     (directly or indirectly) for the acquisition of land (or an interest
     therein) and none of such land shall be used (directly or indirectly) for
     farming purposes,

          (v)    with respect to any building and the equipment therefor (or an
     interest therein) acquired with the proceeds of the Bonds, the first use of
     which is not pursuant to such acquisition, rehabilitation expenditures (as
     defined in Section 147(d) of the Code) for such building will equal or
     exceed 15 percent of the portion of the cost of acquiring such building
     (and equipment) financed with the proceeds of the Bonds, and such
     rehabilitation expenditures will be incurred within two years after the
     later of the date such building was acquired or the Closing Date, and

          (vi)   with respect to any facilities other than buildings acquired
     with proceeds of the Bonds, the first use of which is not pursuant to such
     acquisition, rehabilitation expenditures (as defined in Section 147(d) of
     the Code) for such facility will equal or exceed 100 percent of the portion
     of the cost of acquiring such facility financed with the proceeds of the
     Bonds, and such rehabilitation expenditures will be incurred within two
     years after the later of the date such facility was acquired or the Closing
     Date.

     (g)  The Borrower shall comply with all effective rules, rulings or
regulations promulgated by the Department of the Treasury or the Internal
Revenue Service with respect to obligations issued under Section 144(a) of the
Code as a "qualified small issue bond" the interest on which is exempt from
federal income taxation.

     (h)  The Borrower covenants that it will refrain, and it will cause all
principal users, as defined in Prop. Treas. Reg. (S)1.103-10(h), of the Project
and all related persons, as defined in Section 144(a)(3) of the Code, to
refrain, from incurring or paying for capital expenditures during the six-year
period commencing three years prior and ending three years after the Closing
Date, which would cause the $10,000,000 limitation contained in Section
144(a)(4) of the Code to be exceeded.

     (i)  The Borrower also covenants that it will not cause, or will not take
or omit to take or permit any person to take or omit to take any action which
would cause, the "aggregate

                                       28
<PAGE>
 
authorized face amount" of the Bonds and any exempt facility bonds, as defined
in Section 142 of the Code, qualified small issue bonds or qualified
redevelopment bonds, as defined in Section 144 of the Code, and any industrial
development bonds, as described in Section 103(b)(4), (5), and (6) of the
Internal Revenue Code of 1954, as in effect on the day prior to the adoption of
the Tax Reform Act of 1986, allocated to any owner or "principal user", as
defined in Prop. Treas. Reg. (S)1.103-10(h), including all persons related
thereto within the meaning of Section 144(a)(3) of the Code, of the Project at
any time during the three year period beginning on the later of the date the
Project is placed in service or the Closing Date, as described in Section
144(a)(10) of the Code, to exceed $40,000,000.

     (j)  Neither the Issuer nor the Borrower shall take any action or omit to
take any action with respect to the proceeds of sale of the Bonds or of any
amounts expected to be used to pay the principal (and premium, if any) thereof
and the interest thereon which, if taken or omitted, respectively, and if
reasonably expected on the date of the initial delivery of the Bonds, would
result in constituting the Bonds "arbitrage bonds" within the meaning of Section
148 of the Code, or take any deliberate action motivated by arbitrage which
would have such result, nor shall the Borrower take or omit to take any other
action which would otherwise adversely affect any exemption under the Code from
federal income taxation of the interest on any Bond.  Further, neither the
Borrower nor the Issuer shall, at any time prior to the final maturity of the
Bonds, directly or indirectly invest Gross Proceeds in any Investment (or use
Gross proceeds to replace money so invested), if as a result of such investment
the Yield from the Closing Date of all Investments acquired with Gross proceeds
(or with money replaced thereby) whether then held or previously disposed of,
exceeds the Yield of the Bonds.  Notwithstanding the foregoing, however, the
following investments shall be excluded from the limitation and calculation
described in this Subsection (j):

          (i)    Investments acquired with proceeds from the sale of the Bonds
     or income from the investment, to the extent such Investments are held
     during the first three years after the Closing Date or prior to the date on
     which the Project has been completed, whichever is shorter;

          (ii)   Investments acquired with income from investment of proceeds
     from the sale of the Bonds, to the extent such Investments are held during
     the first year after receipt of such income;

          (iii)  Investments acquired with amounts held for the credit of the
     Bond Fund, to the extent such Investments are held during the first 13
     months after the date of deposit of such amounts to the Bond Fund; and

          (iv)   any other Investments to the extent the aggregate cost thereof,
     adjusted upward by the amortized portion (calculated on a straight-line
     basis) of any discount at which such Investments were acquired, does not
     exceed the lesser of 5% of the proceeds from the sale of the Bonds of
     $100,000.

                                       29
<PAGE>
 
The Borrower shall pursue work on the Project with due diligence until
completion.  Neither the Borrower nor the Issuer shall (a) use any money to pay
principal or interest on the Bonds, or pledge (or permit to be pledged) or
otherwise restrict any money, funds or Investments so as to give reasonable
assurance of their availability for such purpose, except in each case amounts
deposited to the Bond Fund, or (b) apply any proceeds from the sale of the Bonds
or income from the investment thereof, directly or indirectly, to pay principal
of or interest on any other indebtedness of the Issuer.

     (k)  The Borrower shall not take any action or willfully omit to take any
action with respect to the proceeds of the loan made hereunder or the Project
which, if taken or omitted, respectively, would adversely affect any exemption
from inclusion in gross income for purposes of income taxation of interest on
any Bond under the Code.  All parties hereto agree to execute such amendments
and supplements hereto (and to comply with the provisions thereof) as may, in
the Opinion of Counsel, be necessary to preserve or perfect any exemption from
inclusion in gross income for purposes of federal income taxation of interest on
any Bond under the Code.

     (1)  The Issuer and the Borrower covenant that, no later than the 15th day
of the second calendar month after the close of the calendar quarter in which
the Bonds are issued, the Issuer shall file with the Secretary of the Treasury
the information required to be filed pursuant to Section 149(e) of the Code.
The Borrower covenants that it shall furnish to the Issuer in a timely manner
whatever information is necessary for the Issuer to make such filing.

     (m)  Neither the Issuer nor the Borrower shall take, or omit to take any
action which, if taken or omitted, would cause the Bonds to be "federally
guaranteed" within the meaning of Section 149 of the Code.

     Section 7.13.  Compliance with Applicable Laws.  The Borrower agrees to
                    -------------------------------                             
construct, operate and maintain the Project in accordance with all applicable
Federal, State, county and municipal laws, ordinances, rules and regulations now
in force or that may be enacted hereafter including, but not limited to such
environmental protection, workers' compensation, sanitary, safety, non-
discrimination and zoning laws, ordinances, rules and regulations as shall be
binding upon the Borrower.

     Section 7.14.  Environmental Compliance.  The Borrower shall not permit
                    ------------------------                                    
any action to occur which would be in direct violation of any and all applicable
Federal, State, county and municipal laws, ordinances, rules and regulations now
in force or hereinafter enacted, including the regulations of the Issuer and the
regulations of the Department of Environmental Protection.

     The Borrower shall give immediate written notice to the Issuer and the
Trustee of any inquiry, notices of investigation or any similar communication,
from the Department of Environmental Protection regarding potential violations
of the Environmental Cleanup Responsibility Act (N.J.S.A. 13:lK-6 et seq.)
and/or the Spill Compensation and Control Act (N.J.S.A. 58:10-23.11 et seq.).

     Section 7.15.  Assignment of Loan Agreement.  The Borrower may not
                    ----------------------------                           
assign or transfer the whole or any part of this Loan Agreement without the
prior express written consent of the Issuer.  Any assignment of this Loan
Agreement by the Borrower without the prior express written consent of the
Issuer shall be void.

     Section 7.16.  Lease or Transfer of Project.  The Borrower shall not
                    ----------------------------                             
lease, sublease, sell or otherwise dispose of any possessory interest in whole
or part of the Project without the prior express written consent of the Issuer.
In the event that the Borrower proposes to lease or sublease the Project or any
portion thereof, the Borrower and the proposed lessee shall submit to the Issuer
an application for project occupants in the form currently in use by the Issuer
and a copy of the proposed lease.  The Issuer may review the proposed lease and
application to determine if it tends to further the public purposes for which
the Issuer was created, and if the Issuer determines that the lease would not
promote these purposes, it may disapprove the proposed lease.

     In making the determination described above, the Issuer may consider, among
other criteria, (i) if the proposed occupancy complies with the conditions
specified in the Act for the Issuer's assistance to "projects" as defined in the
Act; (ii) if the proposed occupancy is consistent with the provisions respecting
tax-exempt qualified small issue bond financings set forth in Section 144 of the
Code; and (iii) if the proposed lease will result in the loss of employment for
a substantial number of New Jersey workers by reason of relocating the business
of the lessee from one part of the State to another or for any other reason

     If the Issuer fails to deliver notice of either approval or disapproval of
a proposed lease within twenty (20) days from the day the Issuer receives a
proposal for the lease, including all of the information identified above and
such other information as the Issuer may reasonably require, the proposed lease
shall be deemed to be approved by the Issuer.  The Borrower shall promptly send
a copy of each executed lease to the Issuer.

     Section 7.17.  Inspection of the Project.  The Borrower agrees that the
                    -------------------------                                   
Issuer and its duly authorized agents shall have the right, at all reasonable
times and upon prior notice, to enter upon and to examine and inspect the
Project.  The Issuer and its respective officers and agents shall also be
permitted, at all reasonable times and upon prior notice, to examine the books
and records of the Borrower with respect to the Project and to make copies or
abstracts thereof.

     Section 7.18.  Relocation of the Project.  The Borrower covenants and
                    -------------------------                                 
agrees that during the term of this Loan Agreement it will not relocate the
Project or a substantial number of its employees to another location either
within or without the State without first obtaining the prior express written
consent of the Issuer.

     Section 7.19.  Payment of Prevailing Wage.  Notwithstanding the
                    -------------------------- 
provisions of Section 7.9 hereof, the Borrower shall, in every Construction
Contract to which it is a party, require the Contractor to pay workers engaged
in the performance of such Construction Contract a wage rate not less than the
Prevailing Wage Rate.  The Borrower shall further require, in every Construction
Contract to which it is a party, that the Contractor execute the Contractor's

                                       31
<PAGE>
 
Certificate and Agreement, submit certified copies of payroll records to the
Issuer as required by the Issuer, and execute and file the Contractor's
Completion Certificate.

     Section 7.20.  Affirmative Action.  The Borrower shall require, in
                    ------------------                                     
every Construction Contract to which it is a party, that the Contractor make a
good faith effort to hire, or cause to be hired, minority workers in such job
classifications, trades and crafts and for such percentages of the total hours
of construction work in each trade or craft as shall be necessary to satisfy the
minority employment goals established in the Affirmative Action Program.  The
Borrower shall further require, in every Construction Contract to which it is a
party, that the Contractor or Contractors execute the Contractor's Certificate
and Agreement and submit to the Issuer any certificates, reports and records as
may be necessary to demonstrate the Contractor's compliance with the Affirmative
Action Program.

     The Borrower agrees to include in all construction bid specifications for
the Project and in every Construction Contract to which it is a party, such
terms, conditions and provisions as are prescribed in the Affirmative Action
Program.

     The Borrower agrees to include or cause to be included in every
Construction Contract to which it is a party, a provision, term or condition

                   ASSIGNMENT; INDEMNIFICATION; REDEMPTION;
                           RESERVATION OF INTERESTS

     Section 8.1.  No Assignments Except as Permitted.  The Borrower shall
                   ----------------------------------                         
not, without the prior written consent of the Issuer, the Trustee and the Bank,
assign its interests under this Agreement.

     In addition, prior to any assignment and as a condition precedent to the
validity thereof, the Issuer shall cause to be filed with the Trustee an opinion
of an attorney or firm of attorneys experienced in matters relating to municipal
bonds to the effect that such assignment will not adversely affect the status of
the interest on the Bonds as exempt from inclusion in the gross income of the
recipients thereof for purposes of federal income taxation.

     Notwithstanding the foregoing, this Agreement shall be expressly subject
and subordinate to the assignment and pledge by the Issuer to the Trustee
pursuant to the Indenture of its interests in this Agreement and any moneys
receivable under this Agreement.

     Section 8.2.  Release and Indemnification Covenants.
                   -------------------------------------     

     (a)  The Borrower shall and hereby agrees to defend and indemnify and save
     the Issuer and the Trustee harmless against and from all claims by or on
     behalf of any person, firm, corporation or other legal entity arising from
     the conduct or management of, or from any work or thing done on, the
     Project or the Facilities during the term of this Agreement, including
     without limitation, (i) any condition of the Project or the Facilities,
     (ii) any breach or default on the part of the Borrower in the performance
     of any of its obligations under this Agreement, (iii) any act or negligence
     of the Borrower or of any of its agents, contractors, servants, employees
     or licensees or (iv) any act or negligence of any assignee or lessee of the
     Borrower, or of any agents, contractors, servants, employees or licensees
     of any assignee or lessee of the Borrower.  The Borrower shall defend and
     indemnify and save the Issuer and the Trustee harmless from any such claim
     arising as aforesaid, or in connection with any action or proceeding
     brought thereon, and upon notice from the Issuer or the Trustee, the
     Borrower shall defend them or either of them in any such action or
     proceeding; provided that such defense shall be undertaken by counsel
     reasonably acceptable to the party being defended, such counsel to be
     deemed approved if not disapproved by such party within twenty (20) days of
     notice by the Borrower of the name of such counsel.

     (b)  Notwithstanding the fact that it is the intention of the parties
     hereto that the Issuer shall not incur any pecuniary liability by reason of
     the terms of this Agreement or the undertakings, required of the Issuer
     hereunder, by reason of the issuance of the Bonds, by reason of the
     execution of the Indenture or by reason of the performance of any act
     requested of the Issuer by the Borrower, including all claims, liabilities
     or losses arising in connection with the violation of any statutes or
     regulation pertaining to the foregoing;

                                       34
<PAGE>
 
     nevertheless, if the Issuer should incur any such pecuniary liability, then
     in such event the Borrower shall indemnify and hold the Issuer harmless
     against all claims, demands or causes of action whatsoever, by or on behalf
     of any person, firm or corporation or other legal entity arising out of the
     same or out of any offering statement or lack of offering statement in
     connection with the sale or resale of the Bonds and all costs and expenses
     incurred in connection with any such claim or in connection with any action
     or proceeding brought thereon, and upon notice from the Issuer, the
     Borrower shall defend the Issuer in any such action or proceeding.  All
     references to the Issuer in this Section 8.2 shall be deemed to include its
     members, officers, employees and agents.

     Notwithstanding anything to the contrary contained herein, the Borrower
shall have no liability to indemnify the Issuer or the Trustee against claims or
damages resulting from the Issuer's or the Trustee's own gross negligence or
willful misconduct.

     Section 8.3.  Redemption of Bonds.  The Borrower shall have and is
                   -------------------                                     
hereby granted the option to cause all or a portion of the Bonds to be redeemed
at the times permitted by the Indenture.  The Issuer, at the request of the
Borrower, shall forthwith take all steps (other than the payment of any money
required for such redemption and other than such as are reserved unto the
Trustee) necessary under the applicable redemption provisions of the Indenture
to effect redemption of all or part of the Outstanding Bonds, as may be
specified by the Borrower, on the date established for such redemption.

     Section 8.4.  References to Bonds Ineffective After Bonds Paid.  Upon
                   ------------------------------------------------           
payment in full of the Bonds (or provision for payment thereof having been made
in accordance with the provisions of the Indenture), payment of all fees and
charges of the Trustee and payment of all amounts payable to the Bank under the
Credit Agreement, all references in this Agreement to the Bonds, the Bank and
the Trustee shall be ineffective, and neither the Trustee, the Bank nor the
Owners of any of the Bonds shall thereafter have any rights hereunder, saving
and excepting those that shall have theretofore vested or would affect the tax-
exempt status of the Bonds.

     Section 8.5.  Issuer to Grant Security Interest to Trustee.  The
                   --------------------------------------------          
parties hereto agree that pursuant to the Indenture, the Issuer shall pledge,
assign and transfer to the Trustee in order to secure payment of the Bonds and
of amounts payable to Bank in respect of the Letter of Credit and the Credit
Agreement, all of the Issuer's rights, titles and interests in, to and under
this Agreement, excepting Issuer's rights under Section 6.1(b), 6.1(d), 7.4(e),
7.4(g), 7.8(f), 7.15, 7.16, 8.2 and 9.4 hereof, and in, to and under the
Borrower's Note.

                             DEFAULTS AND REMEDIES

     Section 9.1.  Defaults Defined.  The following shall be "Defaults"
                   ----------------                                        
under this Agreement and the term "Default" shall mean, whenever it is used in
this Agreement, any one or more of the following events:

     (a)  failure by the Borrower to pay any amount required to be paid under
     subsection (a) of Section 6.1 hereof or under Section 6.5 hereof, in either
     case, as and when due, or failure by the Borrower to pay any amount
     required to be paid under subsection (b) or (c) of Section 6.1 hereof
     within five (5) days of written notice of such amount; or

     (b)  failure by the Borrower to observe and perform any covenant, condition
     or agreement on its part to be observed or performed, other than as
     referred to in Subsection 9.1(a) above, for a period of thirty (30)
     Business Days after written notice specifying such failure and requesting
     that it be remedied shall have been given the Borrower by the Issuer or the
     Trustee (and if by the Issuer with the approval of the Trustee and the
     Bank), unless the Issuer and the Trustee shall agree in writing to an
     extension of such time prior to its expiration; provided, however, if the
     failure stated in the notice cannot be corrected within the applicable
     period, neither the Issuer nor the Trustee, as the case may be, will
     unreasonably withhold consent to an extension of such time if corrective
     action is instituted by the Borrower within the applicable period and
     diligently pursued until such failure is corrected; or

     (c)  the dissolution or liquidation of the Borrower, or the voluntary
     initiation by the Borrower of any proceeding under any federal or state law
     relating to the bankruptcy, insolvency, arrangement, reorganization,
     readjustment of debt or any other form of debtor relief, or the initiation
     against the Borrower of any such proceeding which shall remain undismissed
     for sixty (60) days, or failure of the Borrower to promptly have discharged
     any execution, garnishment or attachment of such consequence as would
     impair the ability of the Borrower to carry on its business operations, or
     assignment by the Borrower for the benefit of creditors, or the entry of
     the Borrower into an agreement of composition with creditors or the failure
     generally by the Borrower to pay its debts as they become due; or

     (d)  the occurrence of a Default under the Indenture.

The provisions of subsection (b) of this Section are subject to the following
limitation: if by reason of force majeure the Borrower is unable in whole or in
                            ----- -------                                      
part to carry out any of its agreements contained herein (other than its
obligations contained in Article VI hereof), the Borrower shall not be deemed in
Default during the continuance of such inability.  The term "force majeure" as
                                                             -------------    
used herein shall mean, without limitation, the following: acts of God; strikes
or other industrial disturbances; acts of public enemies; orders or restraints
of any kind of the government of the United States of America or of the State or
of any of their departments,

                                       36
<PAGE>
 
agencies or officials, or of any civil or military authority; insurrections;
riots; landslides; earthquakes; fires; storms; droughts; floods; explosions;
breakage or accident to machinery, transmission pipes or canals; and any other
cause or event not reasonably within the control of the Borrower.  The Borrower
agrees, however, to remedy with all reasonable dispatch the cause or causes
preventing the Borrower from carrying out its agreement, provided that the
Borrower shall not be unreasonably required to settle any strike or industrial
disturbance.

     Nothing contained in this Section 9.1 shall limit the rights and remedies
of the Bank under the Credit Agreement in respect of defaults thereunder.

     Section 9.2.  Remedies on Default.  Whenever any Default referred to in
                   -------------------                                          
Section 9.1 hereof shall have happened and be continuing, then, subject to the
proviso of the final paragraph of Section 9.3 hereof, the Trustee or the Issuer
with the written consent of the Trustee may take one or any combination of the
following remedial steps:

     (a)  if the Trustee has declared the Bonds immediately due and payable
     pursuant to Section 6.02 of the Indenture, by written notice to the
     Borrower, declare an amount equal to all amounts then due and payable on
     the Bonds, whether by acceleration or maturity (as provided in the
     Indenture) or otherwise, to be immediately due and payable as liquidated
     damages under this Agreement and not as a penalty, whereupon the same shall
     become immediately due and payable;

     (b)  have reasonable access to and inspect, examine and make copies of the
     books and records and any and all accounts, data and income tax and other
     tax returns of the, Borrower during regular business hours of the Borrower
     (except books, records, accounts and other information which the Borrower
     is required by law to keep confidential) if reasonably necessary in the
     opinion of the Trustee; or

     (c)  take whatever action at law or in equity may appear necessary or
     desirable to collect the amounts then due and thereafter to become due, or
     to enforce performance and observance of any obligation, agreement or
     covenant of Borrower under this Agreement or the Borrower's Note.

     Any amounts collected pursuant to action taken under this Section shall be
paid into the Bond Fund and applied in accordance with the provisions of the
Indenture.

     Section 9.3.  No Remedy Exclusive.  Subject to Section 6.02 of the
                   -------------------                                     
Indenture, no remedy herein conferred upon or reserved to the Issuer or the
Trustee is intended to be exclusive of any other available remedy or remedies,
but each and every such remedy shall be cumulative and shall be in addition to
every other remedy given under this Agreement or now or hereafter existing at
law or in equity.

     No delay or omission to exercise any right or power accruing upon any
Default shall impair any such right or power or shall be construed to be a
waiver thereof, but any such right or power may be exercised from time to time
and as often as may be deemed expedient.  In order to

                                       37
<PAGE>
 
entitle the Issuer or the Trustee to exercise any remedy reserved to it in this
Article, it shall not be necessary to give any notice, other than such notice as
may be required in this Article; PROVIDED, HOWEVER, that prior to the Letter of
Credit Termination Date and so long as the Bank shall not have failed to make
lawful payment under the Letter of Credit in accordance with the terms and
conditions of the Letter of Credit, neither the Issuer nor the Trustee shall
exercise any such remedy without the prior consent of the Bank.  Such rights and
remedies as are given the Issuer hereunder shall also extend to the Trustee, and
the Trustee and the Owners of the Bonds, subject to the provisions of the
Indenture, shall be entitled to the benefit of all covenants and agreements
herein contained.

     Section 9.4.  Agreement to Pay Attorneys' Fees and Expenses.  In the
                   --------------------------------------------- -            
event the Borrower should Default under any of the provisions of this Agreement,
and the Issuer or the Trustee should employ attorneys or incur other expenses
for the collection of payments required hereunder or the enforcement of
performance or observance of any obligation or agreement on the part of the
Borrower herein contained, the Borrower agrees that it will on demand therefor
pay to the Issuer and the Trustee, as the case may be, the reasonable fee of
such attorneys and such other expenses so incurred, and any such amounts paid by
the Issuer and the Trustee shall be added to the indebtedness secured by the
Indenture.

     Section 9.5.  No Additional Waiver Implied by One Waiver.  In the event
                   ------------------------------------------                   
any agreement contained in this Agreement should be breached by either party and
thereafter waived by the other party, such waiver shall be limited to the
particular breach so waived and shall not be deemed to waive any other breach
hereunder.

with the consent of the Trustee and the Bank, but without the consent of the
Owners of any of the Bonds Outstanding, may enter into supplements to this
Agreement and the Note which shall not be inconsistent with the terms and
provisions hereof for any of the purposes heretofore specifically authorized in
this Agreement or the Indenture, and in addition thereto for any one or more of
the following purposes:

     (a) so as to more precisely identify the Project or the Facilities, or to
     substitute or add additional improvements or equipment to the Protect, or
     additional rights or interests in property acquired in accordance with the
     terms of this Agreement;

     (b) to cure any ambiguity or formal defect or omission in this Agreement or
     the Borrower's Note or, if required or otherwise appropriate, to conform
     the provisions or requirements of this Agreement or the Borrower's Note to
     the terms of, including any subsequent change therein, the Indenture;

     (c) to enter into an indenture or indentures supplemental to the Indenture
     as provided in Article VIII of the Indenture;

     the Bonds of at least AA/A-1;

     (e) by addition or deletion, to conform to the requirements of or
     procedures authorized under this Agreement, to such additional
     requirements, limitations or prohibitions as may be made under the Code
     with respect to obligations of the character of the Bonds, the use of
     proceeds of the Bonds and investment earnings thereon and the conversion of
     the interest rate on the Bonds;

     (f) by addition, to include covenants governing the Borrower's financial
     affairs to the extent reasonably required in connection with the Borrower's
     exercise of its Conversion Option; or

     (g) to effect any other change herein which, in the judgment of the
     Trustee, is not to the prejudice of the Trustee or the Owners of the Bonds.

     Section 10.2.  Amendment Upon Approval of Two-Thirds of Owners of
                    --------------------------------------------------
Bonds.  Except for the amendments, changes or modifications as provided in
Section 10.1 hereof, no other amendment, change or modification of this
Agreement or the Borrower's, Note shall be undertaken without the mailing of
notice of such proposed amendment, change or modification to and the written
approval or consent of the Bank and the Owners of at least two-thirds (2/3) in

                                       39
<PAGE>
 
aggregate principal amount of the Outstanding Bonds given as in this Section
provided, provided that the consent of the Bank and the Owners of all Bonds
Outstanding is required for any amendment, change or modification of this
Agreement that would permit the termination or cancellation of this Agreement or
a reduction in or postponement of the payments under this Agreement or the
Borrower's Note or any change in the provisions relating to payment hereunder or
thereunder.

     If at any time the Issuer and the Borrower shall request the consent of the
Trustee to any such proposed amendment, change or modification of this Agreement
or the Borrower's Note, the Trustee shall, upon being satisfactorily indemnified
with respect to expenses, cause notice of such proposed amendment, change or
modification to be given to the Bank, and each national rating agency by which
any of the Bonds are then rated and to the Owners of the Bonds by mailing notice
by registered or certified mail to the Owner of each Bond at the address shown
on the registration books.  Such notice shall briefly set forth the nature of
such amendment, change or modification and shall state that copies thereof are
on file at the Principal Office of the Trustee for inspection by all Owners of
Bonds.  If, within sixty (60) days or such longer period as shall be prescribed
by Issuer following such notice, the Owners of not less than (a) two-thirds
(2/3rds) in aggregate principal amount of or, as may be required, (b) all the
Outstanding Bonds at the time of the execution of any such proposed amendment,
change or modification shall have consented to and approved the execution
thereof as herein provided, no Owner of any Bond shall have any right to object
to any of the terms and provisions contained therein, or the operation thereof,
or in any manner to question the propriety of the execution thereof, or to
enjoin or restrain the Trustee, the Borrower or the Issuer from executing the
same or from taking any action pursuant to the provisions thereof.  Upon the
execution of any such proposed amendment, change or modification as in this
Section permitted and provided, this Agreement or the Borrower's Note shall be
and be deemed to be modified and amended in accordance therewith.

     The Issuer, the Borrower and the Trustee shall be entitled to receive, and
shall be fully protected in relying upon the opinion of counsel, who may be
counsel for the Issuer, as conclusive evidence that any such proposed supplement
or amendment, change or modification complies with the provisions of this
Agreement and the Indenture and that it is proper for the Issuer, and the
Trustee under the provisions of this Article to execute and approve the same.
