     3.2  Maximum Output of Cogeneration Facility.



     The maximum required output of steam from the Cogeneration Facility is

set forth in Appendix A attached hereto.  Seller is not obligated to

deliver amounts in excess of that amount.



     3.3  Purchase of Steam from Alternative Sources.



     Unless an event of Force Majeure excuses it from doing so, Buyer will

purchase the amount of steam which it requires at its Plant at the price

set forth in Article 6.  If, for any reason, the Seller cannot produce all

of the steam required by



                              10







Buyer (up to the maximum amount set forth in Appendix A), Buyer may,

without incurring any liability hereunder, use steam or alternate energy

from other sources to make up that portion of its requirements which Seller

fails to supply.  If Buyer incurs any out-of-pocket expenses in connection

with obtaining steam or an alternative energy from another source or

sources (other than amounts of excess of the amount set forth in Appendix

A), as a result of Seller's inability to comply with this Agreement due to

the occurrence of an event of Force Majeure, then, Seller shall either, at

Seller's option, (i) pay Buyer's Specified Damages or (ii) give Buyer

reasonable advance notice of the date on which it will be able to resume

providing steam and not require Buyer to resume its purchase of steam

hereunder until a reasonable period of time (not to exceed 45 business

days) after receipt by Buyer of notice of anticipated resumption of service

(the reasonableness of the notice period being determined based on the

expenses incurred by Buyer in arranging for alternative source of supply of

steam or other (fuel).  Buyer shall be entitled to rely on any notice

received from Seller.



     The Parties further acknowledge that it may be necessary or prudent,

in light of the limited number of alternative sources of supply of steam

available, for Buyer to secure an alternative source of steam which has a

greater capacity than that which Buyer requires.  Seller agrees to make

available to Buyer its employees who operate boilers to the extent it can

do so without impairing its ability to operate the Facility.



     Nothing in this Agreement is intended or shall be



                              11







construed as requiring Buyer (or any subsequent owner of the Plant) to use

steam rather than any other energy source (including, but not limited to,

electricity) in the operation of the Plant, other than as set forth in the

second to the last sentence Section 3.1.  Nor is this Agreement intended to

impose on Buyer any obligation to purchase any minimum amount of steam at

any time other than that amount specified in Appendix A.

                                     

                                 ARTICLE 4

                                     

                     RESPECTIVE RIGHTS AND OBLIGATIONS

                                     

     4.1  Rights and Obligations of Seller.



     Seller covenants and agrees that during the term of this Agreement it

shall:



     A.   Design, construct, start up, test and operate the Cogeneration

Facility at its expense in accordance with safe and sound engineering

practices and procedures in order that the Cogeneration Facility is able at

all times to deliver steam meeting the specifications set out in Appendix A

and in the quantities set forth in Appendix A.  The Cogeneration Facility

shall utilize Buyer's existing boilers as a back-up system.  Seller shall

have the right to use such boilers at not charge on the condition that:

(1) it pays for any fuel consumed as well as any associated operation and

maintenance costs; (2) it installs and pays for any necessary

interconnections with Seller's Cogeneration Facility and (3) it keeps such

boilers "hot", at Seller's expense, by circulating steam through them once

the Cogeneration Facility is operational.  Should Seller determine at any

time during this Agreement that replacement of Buyer's boilers is

necessary, it shall bear the cost of such replacement and the new boiler(s)

shall become the property of Seller, and shall be added to the Cogeneration

Facility.



     B.   If Seller uses the original site (as opposed to Alternate Site),

design construct and maintain a "park and lock" parking garage on the Site

with sufficient spaces to replace those spaces eliminated by Seller on the

Site as a result of the construction of the Cogeneration Facility.  Seller

shall



                              12







guarantee continued access to this parking garage for Buyer's employees and

the right, at no cost, to use an equivalent number of spaces to those

eliminated by Seller.  At the conclusion of this Agreement or at any time

when Buyer has the right to purchase the Cogeneration Facility Buyer shall

have the right to purchase the Cogeneration Facility.  The price for the

garage shall be its fair market value, as determined by the American

Appraisal Company, the appraisal to be based on the assumption that the

garage sits on freehold property (rather than leased property), less the

value of the freehold.  In other words, the value of the real property on

which the garage rests will be ignored in the appraisal.

     

     C.   Obtain those permits set forth in Appendix C hereto and any other

additional permits which may be required under then applicable and

regulations to operate the Facility during the term of this Agreement.

     

     D.   Provide to Buyer for its review all design drawings of the

Cogeneration Facility, the Parking Garage and Steam Interconnection

Facilities.  Seller shall also give Buyer an opportunity to review its

construction plan prior to the commencement of construction in order that

Buyer can assure itself that construction of the Cogeneration Facility will

not interfere with Buyer's on-going operations.  Buyer shall have the right

to approve such construction plan or any modifications thereto, such

approval not to b unreasonably withheld.  Buyer shall use its best efforts

to review and approve such plans within 15 days

     

                              13

     





of receipt from Seller.  To insure coordination between Buyer and Seller

during construction, Buyer shall designate a single individual with whom

Seller may consult during construction of the Cogeneration Facility.

Seller shall also designate a single individual with whom Buyer may consult

during construction or operation of the Cogeneration Facility.  Buyer's

review of the construction plan and design drawings shall not relieve

Seller of any of its obligations pursuant to Section 4.1A hereof;

     

     E.   Maintain the Cogeneration Facility in good operating condition,

in compliance with all applicable governmental requirements and in

accordance with reasonable business practice, and use its best efforts (i)

at a time that is mutually agreeable to the Parties, (ii) to ensure that

any interruptions will be planned to coincide with the scheduled

maintenance outages of the Plant, notice of which shall be given to the

Chief Plan Engineer designated by Buyer promptly and shall comply with

Article 20 hereof, and (iii) to minimize the frequency and duration of any

periods of interruption of delivery of steam meeting the specifications set

forth in Appendix A hereof to Buyer's requirements therefor, up to the

maximum required output of the Cogeneration Facility set forth in Appendix

A.



     F.   Have the right to generate and sale steam or electricity or both

to any person other than Buyer on any terms and conditions, without

interference by Buyer, provided that Seller

     

                              14

     





may do so without impairing its ability to fulfill its obligations under

this Agreement.



     G.   Furnish, operate and maintain, at its own expense, all Steam

Interconnection Facilities necessary for the delivery of steam from its

Cogeneration Facility to and including the Steam Point of Delivery, and the

receipt of Condensate into its Cogeneration Facility from and including the

Point of Return.



     H.   Operate and maintain all necessary electrical transmissions

facilities to deliver electricity from the Cogeneration Facility to its

electricity customers, in a safe manner without creating an unreasonable

risk of injury or damage to Buyer's personnel or property;



     I.   Operate the Cogeneration Facility in substantial compliance with

all applicable federal, state and local environmental standards, and all

other applicable laws, rules and regulations and make all necessary filings

with and send all required notices relating to the Facility to the

     J.   Designate a Cogeneration Facility Engineer to maintain

communications with Buyer's Chief Plant Engineer for coordination between

the Plant and the Cogeneration Facility during the term of this Agreement,

which Cogeneration Facility Engineer shall be available to meet with

buyer's Chief Plant Engineer; and

     

     K.   Give to Buyer prompt notice, either written or oral, of

Condensate which does not meet the standards of Condensate quality set

forth in Appendix D specifying how such

     

                              15

     





standards are not met.



     4.2  Rights and Obligations of Buyer.

                             TERM OF AGREEMENT

                                     

     5.1  Effective Date and Term.



     A.   Except as otherwise provided in Article 15 or 16, the term of

this Agreement shall begin upon the execution of this Agreement, and shall

terminate on December 31, 1997 unless the conditions precedent specified in

Section 5.4 are then satisfied or compliance therewith waived.  Steam

supply and invoicing for steam delivered in accordance with this Agreement

shall begin on the Initial Delivery Date.  If the conditions precedent set

forth



                              19







in Section 5.4 hereof are satisfied in a timely manner or compliance

therewith waived, then, subject to the provisions of Section 5.3, (i) this

Agreement shall continue in effect for an initial term ending twenty-five

(25) years after the initial Delivery Date (the "Initial Termination Date")

and (ii) unless either Party gives to the other notice of termination at

least eighteen (18) months prior to the Initial Termination Date, this

Agreement will continue for successive additional terms of five (5) years

each (the "Extended Termination Date"); subject, however, to expiration at

the end of the then current term.



     B.   Notwithstanding the foregoing or any other provision in this

Agreement, Buyer may sell the Plant to an unrelated third party, and be

released from any and all liabilities and obligations hereunder (with the

exception of continuing the Site lease) arising on or after the sale date

if it complies with the following conditions:



     (1)  In negotiating any sale of the Plant to a purchaser who intends

to use the Plant as a manufacturing facility, Buyer agrees to include

Buyer's rights and liabilities hereunder as part of the Buyer's assets

being sold with the Plant and to require any purchaser of its Plant to

assume all of Buyer's obligations under this Agreement, except as otherwise

provided in the following sentence.  The purchaser shall be obligated to

pay the purchase price for steam determined in accordance with Article 6

hereof (the "Contract Price") unless it presents to Seller a bona-fide,

written offer ("Offer") that it has received that is



                              20







then valid to supply either steam or an alternative fuel source to the

purchaser in an amount not less than the amount specified in Appendix A

hereof (or, in the case of an alternative fuel source, the equivalent

amount of power).  In the event that the purchaser submits written proof of

an Offer to Seller, then Seller covenants and agrees to enter into an

agreement with such purchaser amending the terms of this Agreement to meet

the terms of the Offer.  Failure of Seller to agree to such an amendment

shall relieve Buyer of any and all obligations to include Buyer's rights

and liabilities hereunder as part of Buyer's rights assets being sold with

the Plant.  However, in the event that Seller and the proposed purchaser of

the Plant cannot reach agreement, Buyer shall give Seller the first right

to purchase the Plant on the same terms and conditions as contained in the

proposal submitted by Buyer's prospective purchaser.  If such proposal

calls for Buyer to take back any financing, Seller shall demonstrate that

it has similar financial capabilities to those of Buyer's prospective

purchaser or provide Buyer with additional security for the loan provided

by Buyer.  Furthermore, if the purchase offer includes other assets owned

by Buyer at the same location, Seller shall also purchase these other

assets on the same terms, if it chooses to exercise this option.  Finally,

if Seller does exercise this option, Buyer may also require it to purchase

the Site at fair market value, if such site is not already owned by Seller.

Seller shall have 10 days in which to meet such terms.  If it fails to do

so, Buyer may proceed with the sale of the Plant pursuant to the terms of

this paragraph.



                              21







     (2)  In the event that Buyer proposes to sell the Plant to a purchaser

who intends to either tear down the Plant or use it other than as a

manufacturing facility, then Buyer shall give Seller ninety (90) days'

prior written notice of the terms and conditions of the proposed sale.  If

within ninety (90) days of receipt of the notice of intended sale, Seller

agrees in writing to purchase the plant on terms and conditions identical

to those specified in Buyer's notice to it, then Seller shall purchase the

Plant on said terms and this Agreement shall terminate on the date of sale.

If Seller does purchase the Plant, Buyer shall also have the right to

require Seller to purchase the Site at fair market value, if such Site is

not already owned by Seller.  Furthermore, if the purchase offer includes

other assets owned by Buyer at the same location, Sellers shall also

purchase these other assets on the same terms, if it chooses to exercise

this option.



     If Seller elects not to purchase the Plant after having received a

notice from Buyer of Buyer's intention to sell the Plant, then Seller shall

have the right, exercisable only in writing within ninety (90) days of

receipt of the notice of intended sale described in the preceding

paragraph, to purchase the Site for its then fair market value, as

determined by an appraisal of the American Appraisal Company (or similar

appraisal organization), if Seller does not then own the Site.  The

arbitration provisions set forth in Article 18 shall be utilized to settle

any dispute as regards "fair market value".



     If Seller does not elect on a timely basis to either purchase the

Plant or the site in accordance with this Section, then Buyer may sell the

Plant and the site (if then owned by Buyer) to the offerer whose offer was

described in the notice of intention to sell, and this Agreement shall

terminate on the date of sale unless the purchaser of the Plant assumes

Buyer's obliga-



                              22







tions hereunder in accordance with Article 19.



     (3)  Should Buyer decide at any point during the term of this

Agreement to shut down its Plant, it will, in addition to the other options

given Seller under Article 11, give Seller the right to purchase, at a

purchase price mutually acceptable to both Parties, either the Plant or the

steam consuming equipment prior to such shut-down.  If within ninety (90)

days of receipt of the notice of intended shut-down, Seller agrees in

writing either to purchase the Plant or the steam consuming equipment, then

Seller shall purchase said Plant for its then fair market value.  If Seller

does purchase the Plant, Buyer shall also have the right to require Seller

to purchase the site at fair market value, if such Site is not already

owned by Seller.



     If Seller elects not to purchase the Plant or Buyer's steam consuming

equipment, it shall have the right, exercisable only in writing within

ninety (90) days of receipt of notice of intended shutdown from Buyer, to

purchase the Site for its then fair market value, as determined by an

appraisal of the American appraisal Company (or similar appraisal

organization), if Seller does not then own the site.  The arbitration

provisions set forth in Article 18 shall be utilized to settle any dispute

as regards "fair market value".



     If Seller does not elect on a timely basis to either purchase the

Plant, the steam consuming equipment or the Site in accordance with the

provisions of this section, then (i) Seller shall have the right to remove

all of its equipment prior to the date of Plant shutdown, (ii) Buyer shall

have the right to require Seller to remove the Facility if Seller does not

own the Site and (iii) this Agreement shall terminate on the date of such

shutdown.



     C.   At the end of the term of this Agreement, any easements, permits

of other rights granted to Seller by Buyer shall terminate.



                              23







     5.2  Buyer's Right to Purchase Cogeneration Facility and Site.



     Buyer shall have an option to purchase the Cogeneration Facility and

the Site (if then owned by Seller) from Seller at each of the following

times:  (i) upon the expiration of this agreement or any subsequent

renewal; and (ii) to the extent specified in Section 16.4, upon the

occurrence of an Event of Default by Seller.  Buyer will provide Seller six

(6) months' prior notice of its intention to exercise such option other

than if it elects to purchase the Facility, and the Site and upon the

occurrence of an Event of Default by Seller.  To the extent permitted by

the pertinent contracts, Buyer shall assume all of Seller's obligations,

rights and duties under all contracts for the sale of electricity and for

the purchase of fuel for the Cogeneration Facility.  Seller shall give

Buyer all relevant information on such contracts as well as information on

the operation of the Cogeneration Facility.  If requested to do so by

Buyer, Seller covenants and agrees to use its best efforts to obtain any

consents which may be necessary in order for Buyer to assume any of

Seller's contracts relating to the Cogeneration Facility.  Buyer will also

indemnify and save Seller harmless from all liability, loss, claims,

actions or suits, including costs and attorneys' fees, arising out of those

contracts solely to the extent that the liability arose subsequent to the

purchase by Buyer of the Cogeneration Facility.



     Seller will indemnify and save buyer harmless form any and all

liability, loss, claims, actions, suits or liabilities, including costs and

attorneys' fees, arising out of either contracts acquired by Buyer or the

operation of the Cogeneration Facility, in either case prior to the

purchase by Buyer of the Cogeneration Facility.



                              24







     The purchase price for the Cogeneration Facility and the Site (if

applicable) will be their fair market value on the date of purchase as

determined by appraisal pursuant to Section 16.6 hereof.  All documentation

for the purchase, assumption and indemnification will be subject to the

reasonable review by and approval of Seller and Buyer.  In determining the

value of the Facility, the appraisers shall ignore the fact that the Site

is lease, and shall value the Cogeneration Facility as if it sat on

freehold property (i.e., with no time limit on its operation other than its

remaining useful life).  In other words, the value of the real estate shall

be ignored.



     5.3  Completion of Cogeneration Facility.



     Subject to Force Majeure, within twenty-four (24) months from the

issuance of all required permits other than a certificate of occupancy for

the Cogeneration Facility, Seller will have (i) completed evaluation of

Buyer's thermal requirements for the Plant; (ii) procured equipment,

designed and constructed the Cogeneration Facility and installed all

equipment necessary for the Cogeneration Facility to operate; and (iii)

given Buyer notice of the Initial Delivery Date, which date shall also be

within thirty (30) months from the issuance of all required permits.



     5.4  Conditions Precedent.



     The Parties' respective obligations under this Agreement are

conditioned upon, and subject to the satisfaction of each of the following

conditions precedent on or prior to December 31, 1987:  (i) Seller's

executing a contract, satisfactory to Seller,



                              25







for the sale by 1 of electricity from the Cogeneration Facility; (ii)

Seller's obtaining a valid air quality permit from the New Jersey

Department of Environmental Protection and all other necessary permits,

authorizations and certifications (other than a certificate of occupancy);

(iii) the Facility's obtaining the status of Qualifying Facility from FERC;

(iv) Seller's obtaining financing that Seller, in its sole discretion,

deems acceptable; (v) Seller's entering into a turnkey contract, to design,

construct, start-up and test the Cogeneration Facility; and (vi) Seller

obtaining a long-term fuel supply.



     Neither Party shall be liable to the other for any termination of this

Agreement pursuant to this Section 5.4 unless the Party failed to discharge

any obligation imposed on it pursuant to this Agreement with respect to its

taking action intended to result in satisfaction of the foregoing

conditions precedent.

                           PAYMENT CALCULATIONS

                                     

     6.1  Steam Price.



     Calculations for steam delivered to Buyer will be made on a daily

basis and totaled at the end of each month.  The price for the steam

delivered will be calculated as follows:

               Buyer's avoided
Steam Price =  fuel cost x (MMBTUs delivered - MMBTUs returned) x .5
               Boiler efficiency

     where:

Buyer's avoided fuel cost      =   The lesser of the price per million BTUs
                                   which Seller pays for natural gas under
                                   its Agreement with PSE&G or the price
                                   per million

                                   BTUs which Buyer would have paid for #2
                                   oil based on the average of 2 bids
                                   received by Buyer for delivery of such
                                   oil.  Buyer shall not be required to
                                   solicit such bids unless (i) it intends
                                   to rely on the price of oil or (ii)
                                   Seller requests it do so.

MMBTUs delivered     =     integrated steam flow x enthalpy  of  steam  (as
          Seller's meter)
     
MMBTUs returned      =     integrated  uncontaminated  Condensate  flow   x
          enthalpy (at Seller's meter)
     
The pressure, temperature and flow of the steam as well as temperature and

flow of the Condensate shall be metered by Seller.  The pressure and

temperature of the steam shall comply with the specifications therefor set

forth in Appendix A.



     Should Buyer and Seller mutually agree on the Alternate Site pursuant

to the provisions of Section 9.2, Seller shall calculate the cost savings

resulting from not having to construct the parking garage described in

Section 4.1(B), which calculation shall be subject to the approval of

Buyer, which approval shall not be unreasonably withheld.  These savings

shall be defined as the difference between (1) the cost of the parking

garage and (2) the cost of acquiring the Alternate Site from Buyer plus the

present value of any additional costs incurred by Seller as a result of its

use of the Alternate Site including, but not limited to, the cost of

running additional steam piping to Buyer's Plant, the cost of buying such

pipe where necessary, and any additional steam losses resulting from longer

pipe runs.



     Any savings realized by Seller shall be allocated 75% to Buyer and 25%

to Seller.  Buyer shall receive its portion of any savings pursuant to this

section through an appropriate additional discount in the price of steam

delivered to Buyer by Seller, such savings to be recovered by Buyer over a

period of 7 years.  This additional discount shall be fixed by mutual

agreement between the parties once the savings have been determined by

Seller.  Any dispute involving the calculations under this section shall be

settled by arbitration pursuant to Article 18.



     6.2  Reimbursement of Power.



     Seller will reimburse Buyer for 190 Kilowatts at Buyer's Public

Service Electric and Gas ("PSE&G") Rate, as the same may be in effect from

time to time.  This reimbursement will be credited on a daily basis, only

while steam is being delivered to Buyer, and totaled at the end of each

month.



                                 ARTICLE 7

                                     

                         MEASUREMENT AND METERING

                                     

     7.1  Measuring Equipment.



     Seller will install, maintain, and operate, at its expense,

instrumentation reasonably acceptable to Buyer for the measurement of steam

flow, Condensate return and any other data necessary for the sale of steam

to Buyer and the computation of an appropriate invoice.  Buyer will have

access to this instrumentation at reasonable hours upon request, but all

instrument reading, calibrating and adjusting will be done only by Seller.



                              27





The determination of the total quantity of steam delivered to Buyer shall

be made by Seller's instrumentation; however, Buyer may install its won

instruments for maintaining information on the quantity of steam being

delivered to it.



     At its own expense, Buyer shall have the right from time to time to

have qualified employees of Buyer or qualified agents of Buyer (in the

presence of Seller) inspect Seller's instrumentation and shall indemnify

Seller from any loss of or damage to any instrumentation caused by Buyer's

employees or agents inspecting the instrumentation.



     The charts and records from Seller's measuring equipment shall remain

the property of Seller and shall be kept by Seller on file for a period of

not less than four (4) years.  At any time within such period Seller shall,

upon request of Buyer, permit Buyer to inspect and verify records and

charts from Seller's measuring equipment, together with calculations

therefrom.



     7.2  Testing



     Seller will maintain the accuracy of its instruments for measuring the

quantity of steam to within plus or minus one percent (1%).  Instruments

will be tested periodically as necessary, but not less than every calendar

quarter.  If Buyer requests that any meter be tested between Seller's

normal testing dates because Buyer believes that the meter may be

inaccurate, Seller will arrange for the meter to be promptly tested.  All

instrument testing will be arranged by Seller and conducted by an

independent testing service satisfactory to Seller and Buyer.



                              28







Seller shall arrange for the prompt repair, at its own expense, of any

equipment which is shown by any test to be necessary or desirable.  Seller

will pay the expense of normal periodic tests; the expense of any test

requested by Buyer will be paid by Buyer unless the test shows that the

instruments are inaccurate by more than plus or minus one percent (1%), in

which case Seller shall pay the expense of testing.  Seller will give Buyer

sufficient notice of any instrument test to enable Buyer or its

representative to witness the test.



     7.3  Corrections



     If any test reveals that Seller's instruments for measuring the

quantity of steam are inaccurate by more than one percent (1%), and

underpayment or overpayment occurs as a result thereof, the aggrieved Party

is entitled to a retroactive billing adjustment as provided in Section 7.4

hereof for the actual period during which inaccurate measurements were

made, if the period can be definitely determined or, if the period cannot

be definitely determined, one-half of the period from the date of the last

previous test of the meter but not to exceed sixty (60) days.  Amounts

reflecting underpayments and overpayments shall be invoiced separately and

are payable immediately upon receipt of the payment invoice.



     7.4  Estimates



     Buyer may, at its option and expense, install and operate check

measuring equipment to check Seller's measuring equipment, but measurement

of Seller's steam and Buyer's Condensate for the purpose of this Agreement

shall be by Seller's measuring equipment only, except in cases hereinafter

specifi-



                              29







cally provided to the contrary.  Any check measuring equipment installed

shall be of a standard type and shall be subject at all reasonable times to

inspection or examination by Seller, but the reading, calibration and

adjustment thereof and changing of charts shall be done only by the

employees or agents of Buyer.



     If, for any reason, any portion of the measuring equipment is out of

service or out for repair so that the quantity of Seller's steam or Buyer's

Condensate delivered cannot be ascertained or computed from the readings

thereof, Seller's steam or Buyer's Condensate delivered during the period

such measuring equipment was out of service or out for repair shall be

estimated and agreed upon by the parties hereto, using the first of the

following methods which is feasible:

          

          (a)  By using the registration of any check measuring

               equipment if installed and accurately registering;

               or

          

          (b)  By estimating the quantity of delivery by

               averaging deliveries during the preceding periods

               under similar conditions, considering the power

               output of the Cogeneration Facility, when the

               measuring equipment was registering accurately.

                           BILLING AND PAYMENTS

                                     

     8.1  Billing.



     On the tenth (10) day of each calendar month, Seller will deliver to

Buyer an invoice for the sale of steam during the



                              30







preceding calendar month.  Each invoice will include all necessary

information for calculation of the payments pursuant to Article 6 of this

Agreement.



     8.2  Payment.



     All payments shown to be due on an invoice shall be due and payable

not later than fifteen (15) days after receipt.



     8.3  Interest.



     If Buyer fails to pay all or any portion of the disputed or undisputed

amounts invoiced within the time stated in Section 8.2, Buyer shall owe

interest on any unpaid portion of the invoice (other than an amount

determined not to be owing), which interest shall accrue at the prime rate

as set by Manufacturers Hanover Trust Company of New York from time to

time, plus two percent (2%), but in no event greater than the maximum

interest rate allowed by law, from the due date until paid.  If interest is

collected on any portion of an invoice later determined to be not properly

owed, than interest shall be repaid to Seller promptly on demand therefor,

together with interest on such amount at the rate specified above.



     8.4  Disputes



     In the event that Buyer disputes an invoice, the undisputed portion of

the invoice shall be due and payable within the time stated in Section 8.2

and payment of the disputed portion shall be resolved in accordance with

the provisions of Article 18 regarding Arbitration of Disputes.

                       LEASE OF SITE AND LAND RIGHTS

                                     

     9.1  Lease of Site.



                              31







     Buyer agrees to lease to Seller, for a term expiring 120 days after

termination of this Agreement, the Site, as described in Appendix E

attached hereto, upon the timely satisfaction of all the conditions

precedent specified in Section 5.4, at an annual lease rate of $1.00 per

year.  This lease shall be added to this Agreement as Appendix F once the

conditions precedent in Section 5.4 have been satisfied.  The Site shall

consist of approximately 1.5 acres, as more fully described in Appendix E

attached hereto.  In addition, Buyer shall provide all necessary easements,

with respect to property owned by Buyer for as long as Seller operates the

Facility, to permit the installation of the Steam Interconnection

Facilities; and to permit Seller to install and maintain such electrical

and steam transmission facilities as shall be necessary to deliver steam or

electricity or both from the Cogeneration Facility to any person other than

the Buyer so long as the same do not interfere with the operation of the

Plant.



     9.2  Alternate Site.



     Buyer has requested that Seller evaluate an Alternative Site for the

Cogeneration Facility.  This location across Lockwood Street from the

Plant, will be evaluated by Seller in good faith to determine if it is

suitable for the Cogeneration Facility.  Buyer recognized that Seller has a

limited amount of time in which to construct the Facility, and therefore,

cannot accept significant delays in obtaining approval for use of this

Alternate Site.  Buyer agrees that either the original Site described in

Appendix E or the Alternate Site (if elected by Buyer) will be available to

Seller in any case and that the final selection of



                              32







the Site will be made no later than February 1, 1987.  Any regulatory,

zoning or other approvals needed to allow Seller to use the Alternate Site

will be Buyer's responsibility and must be in hand prior to February 1,

1987.  If the Alternate Site is feasible in Seller's judgment, Seller

agrees to purchase such Alternate Site (approximately 1.5 acres) from Buyer

at the same price paid by Buyer.



     9.3  Land Rights.



     During the term of this Agreement, each Party grants to the other

Party a license for reasonable ingress and egress over the property owned

or controlled by such Party to the extent the other Party reasonably deems

such ingress or egress necessary in order to examine, test, calibrate or

maintain the Steam Interconnection Facilities and to read meters except

that (i) prior notice of such ingress or egress shall be given except in

the case of an emergency, and (ii) this license shall not be deemed to

establish in a Party any easement or servitude over the other Party's land,

and shall expire with the expiration of this Agreement.

                                     

                                ARTICLE 10

                                     

                      WATER SUPPLY; CONDENSATE RETURN



     10.1 Water Supply.



     Buyer shall provide Seller necessary easements expiring upon the

expiration of this Agreement to permit Seller to construct and operate (i)

water supply facilities capable of meeting Seller's requirements for raw

water (city water), and (ii) conduits, pipes and drain fixtures for the

disposal of any waste water.  Buyer agrees to assist Seller, at Seller's

cost and



                              33







expense, in obtaining any other necessary permits relating to water.

Seller will be responsible for the design, construction, operation and

maintenance of these water supply and waste water disposal facilities and

agrees to indemnify and save Buyer harmless from any loss, claims, actions

or suits, including costs and attorneys' fees, arising out of the

construction, operation or maintenance of said facilities.



     10.2 Condensate Return.



     Buyer will return to the Cogeneration Facility at the point designated

by Seller substantially all of the Plant's steam Condensate.  Condensate

shall be returned by the Buyer to the Facility, as per Appendix D.  Buyer

will be credited for Condensate return in accordance with Section 6.1

hereof.  Buyer will construct at its own expense all pumps and pipes

required to deliver Condensate to Seller from the Plant.

     11.1 Maintenance of Qualifying Facility Status.



     Subject to Force Majeure, Buyer agrees in each calendar year to take

no less than that quantity of thermal energy from the Facility as is

specified on Appendix A hereto.  Should Buyer not take such quantity of

thermal energy from the Facility so as to enable Seller to maintain its

minimum Qualifying Facility status under PURPA, and if Seller is unable to

obtain relief from regulatory authorities as regards its minimum Qualifying

status, seller may, at its option, take the following steps:  (i) acquire

the Site at its then fair market value (if not previously



                              34







purchased) and (ii) obtain from Buyer any addition, easements and rights of

ingress and egress over Buyer's property to conduct an affiliated thermal

consuming business on property acquired by Seller.  Such easements and

rights of ingress and egress, however, shall be limited to those which will

not unreasonably interfere with Buyer's ongoing operations.  In each case,

fair market value is to be determined without regard to the existence of

the Facility on the Site.  The price shall be calculated for raw land

without improvements.  Seller agrees that the foregoing options shall be

its sole remedy in the event that Buyer's requirements for steam fall below

the minimum annual take to ensure continued Qualifying Facility status.



     11.2 Modifications in Plant's Steam Requirements.



     Buyer will also notify Seller ninety (90) days in advance of the

installation or elimination of any major energy consuming or saving

equipment in the Plant and of any material changes in its steam

requirements as soon as possible (defined as more than a twenty percent

(20%) change in consumption of steam from that previous week which change

continues for more than fourteen (14) consecutive days).

     12.1 Obligations of Seller.



     Seller shall be solely responsible for any sales, use, property,

income or other taxes relating to the Cogeneration Facility and its

components or appurtenances or, except as otherwise provided by Section

12.3, the sale of energy produced



                              35







therein.



     12.2 Obligations of Buyer.



     Buyer shall be solely responsible for any sales, use, property, income

or other taxes relating to the Plant, its components or appurtenances or

the sale of the products produced therein.



     12.3 Joint Obligations.



     Buyer and Seller shall each pay one-half of any taxes imposed on the

purchase or sale of steam delivered to the Plant from the Cogeneration

Facility and the return of Condensate from the Plant to the Cogeneration

Facility.

     If either Party is rendered wholly or partly unable to perform its

obligations under this Agreement because of Force Majeure, then, except as

otherwise expressly provided herein, that Party shall be excused from

whatever performance is affected by the Force Majeure solely to the extent

so affected provided that:



     A.   The nonperforming Party will give notice of such Force Majeure

event as soon as possible after the occurrence, which notice may, if given

by Seller, be given orally to the manager of the Plant or other person

designated by Buyer in writing to receive such notice, if confirmed in

writing within two business days.



     B.   The suspension of performance shall be of no greater scope and of

no longer duration than is reasonably required by the Force Majeure.  In

amplification and not in



                              36







limitation of the foregoing, a Force Majeure with respect to Seller's

primary boilers and related equipment shall not excuse Seller's failure to

perform unless the Force Majeure also affects Seller's back-up facilities

for production of steam.



     C.   No obligation of either Party which arose before the occurrence

causing the suspension of performance shall be excused as a result of the

occurrence;



     D.   Buyer's obligation to pay Seller an amount determined pursuant to

Article 6, which obligation arose prior to the occurrence of a Force

Majeure, shall not be excused by Force Majeure claimed by Seller;



     E.   If any of Buyer's equipment, or any part of its system which is

necessary to allow Buyer to accept, transmit or distribute deliveries from

Seller's Cogeneration Facility is damaged because of Force Majeure, the

Force Majeure shall terminate at such time as Buyer is able to repair,

replace, or reconstruct that portion of Buyer's system, including, without

limitation, possession of all necessary materials, equipment, permits,

authorizations, and licenses;



     F.   If any of Seller's equipment, or any part of its system which is

necessary to allow Seller to accept, transmit or distribute deliveries from

Buyer's Plant or to enable Seller to transmit or deliver steam to Buyer, is

damaged because of Force Majeure, the Force Majeure shall terminate at such

time as Seller is able to repair, replace, or reconstruct that portion of

Seller's system, including, without limitation, possession of all necessary

materials, equipment, permits, authorizations, and



                              37







licenses; and



     G.   Nothing herein shall be construed to require a Party to settle

any strike or labor dispute in which it may be involved.  However, in the

event of a strike or labor dispute at either the Cogeneration Facility or

Buyer's Plant, the affected party shall use its best efforts to maintain

its operation by using management personnel when and where appropriate.

Seller shall notify Buyer in writing promptly after it learns of any

impending labor dispute or labor negotiations which might affect Seller's

ability to perform its obligations hereunder.

     15.1 Survival of Representations and Warranties.



     The representations, warranties, covenants and agreements of Buyer and

Seller contained in this Agreement and the respective obligations of the

Parties with respect thereto shall survive the execution of this Agreement

and any investigations made by or on behalf of the Parties and shall

continue in full force and effect until any claims or liabilities with

respect thereto shall be barred by the applicable statute of limitations or

any extensions thereof.  Each of the Parties agrees to give notice to the

breaching Party of any breach of any such representation, warranty,

covenant or agreement, describing such



                              38







breach in reasonable detail, as soon as practicable after the discovery

thereof; provided, however, that the failure to give such notice shall not

relieve the breaching Party from any liability in respect to such breach.



     15.2 Indemnification.



     A.   By Seller.



     Seller agrees to protect, indemnify and hold harmless Buyer and its

directors, officers, employees, agents and representatives against and from

any and all loss, claims, actions or suits, including costs and attorneys'

fees, for or on account of injury, bodily or otherwise, to, or death of,

persons, or for damage to, or destruction of property belonging to Buyer or

others, resulting from, or arising out of or connected with the maintenance

or operation of the Cogeneration Facility including but not limited to, the

delivery of steam to Buyer and the failure of any steam delivered to Buyer

to meet the specifications therefor set forth in Appendix A to this

Agreement, excepting only such injury or harm as may be caused solely by

the malfunction of the Plant or as may be caused solely by the fault or

negligence of Buyer, its directors, officers, employees, agents or

representatives.  Seller shall, upon Buyer's request, defend, at its own

expense, any suit asserting a claim covered by this indemnity.



     B.   By Buyer.



     Buyer agrees to protect, indemnify and hold harmless Seller and its

directors, officers, employees, agents and representatives against and from

any and all loss, claims, actions or



                              39







suits, including costs and attorneys' fees, for or on account of injury,

bodily or otherwise, to, or death of, persons, or for damage to, or

destruction of property belonging to Seller, or others, resulting from or

arising out of or connected with the ownership, maintenance or operation of

the Plant, including, but not limited to, the delivery of Condensate to the

Point of Return and receipt of steam from the Steam Points of Delivery,

excepting only such injury or harm as may be caused solely by the fault or

negligence of Seller, its directors, officers, employees, agents or

representatives or as may be caused by the failure of the steam delivered

to Buyer to meet the specifications therefor set forth in Appendix A to

this Agreement, excepting only such injury or harm as may be caused solely

by the malfunction of the Plant or as may be caused solely by the fault or

negligence of Buyer, its directors, officers, employees, agents or

representatives.  Seller shall, upon Buyer's request, defend, at its own

expense, any suit asserting a claim covered by this indemnity.



     C.   Survival.



     The provisions of this Section 15.2 shall survive the expiration of

the otherwise applicable term of this Agreement.

                      EVENTS OF DEFAULT AND REMEDIES



     16.1 Events of Default by Buyer.



     Buyer shall be in default under this Agreement upon the happening or

occurrence of any of the following events or conditions, each of which

shall be deemed to be an "Event of Default" for purposes of this Agreement:



     (i)  Buyer breaches or fails to observe or perform any of the

obligations, and covenants under this Agreement other than a failure to pay

any amount owed to Seller under Article 8,



                              40







which failure continues for thirty (30) days after written notice from

Seller specifying the nature of such breach or failure and demanding that

it be cured, unless such failure cannot be completely cured within thirty

(30) days after said written notice, in which case an Event of Default

shall exist only if Buyer does not commence and diligently pursue to sure

said failure within thirty (30) days after receipt of said notice.



     (ii) There is an assignment for the benefit of Buyer's creditors, or

Buyer is adjudged a bankrupt, or a petition is filed by or against Buyer

under the provisions of federal bankruptcy laws, or the business or

principal assets of Buyer are placed in the hands of a receiver, assignee

or trustee, or Buyer is dissolved, or Buyer's existence is terminated or

its business is discontinued in substantially all of the places in the

hands of a receiver, assignee or trustee, or Buyer is dissolved, or Buyer's

existence is terminated or its business is discontinued in substantially

all of the places is operates; provided, however, that the events described

in this paragraph (ii) shall not constitute an Event of Default or

otherwise affect the validity of this Agreement so long as (a) compensation

continues to be paid to Seller pursuant to Article 8 of this Agreement, (b)

the terms, covenants and conditions of this Agreement on the part of the

Buyer are performed, and (c) Buyer elects to have the Agreement remain in

effect, in which event this Agreement shall continue to remain in full

force in accordance with the terms herein contained.



     (iii)     Buyer fails to pay, when due, the compensation due Seller as

determined under Article 6 and in accordance with Article 8 of this

Agreement, and such failure continues for a



                              41







period of thirty (30) days following receipt of Buyer of a notice from

shall be deemed to be an "Event of Default" for purposes of this Agreement:



     (i)  Seller fails to perform or observe any of its obligations under

Article 3 or Section 6.2 which failure continues for a period of more than

five (5) consecutive days or more than ten (10) days in any twenty (20) day

period following written notice of such failure from Buyer.



     (ii) Seller fails to observe or perform any of its obligations under

this Agreement other than those covered by clause (i) above which failure

continues for thirty (30) days.



     (iii)     There is an assignment for the benefit of a Seller's

creditors, or Seller is adjudged a bankrupt, or a petition is filed by or

against Seller under the provisions of any state insolvency law or under

the provisions of federal bankruptcy laws, or the business or principal

assets of Seller are placed in the hands of a receiver, assignee or

trustee, or Seller is dissolved, or Seller's existence is terminated or its

business is discontinued; provided, however, that the events described in

this Paragraph (iii) shall not constitute an Event of Default or otherwise

affect the validity of this Agreement, so



                              42







long as Seller continues to provide the services described herein, and so

long as the other terms, covenants and conditions of this Agreement on the

part of Seller are performed, and in such event, this Agreement shall

continue to remain in full force in accordance with the terms herein

contained.



     (iv) Any writ, lien, levy, attachment, execution, or other similar

legal attachment or encumbrance attaches to the Cogeneration Facility and

is not discharged within the lesser of (a) sixty (60) days or (b) the time,

if any, permitted under law for discharge of such attachment or

encumbrance.



     (v)  Any representation or warranty furnished by Seller to Buyer in

connection with this Agreement is false or misleading in any material

respect when made.



     16.3 Remedies Upon Default by Buyer.



     Upon the occurrence of an Event of Default by Buyer, Seller may:



     (i)  Exercise all remedies available at law or at equity or through

other appropriate proceedings including bringing an action or actions from

time to time for recovery of amounts due and unpaid by Buyer, and/or for

damages and expenses resulting from the Event of Default, which shall

include all costs and expenses reasonably incurred in the exercise of its

remedies (including reasonable attorneys' fees), and/or specific

performance.



     (ii) Pursue, concurrently or separately, other remedies existing at

law, in equity or in bankruptcy.



     (iii)     In the event a court orders Buyer to take



                              43







one or more actions pursuant to this Agreement, and such action(s) is a

final order which cannot be appealed, and Buyer fails to take such

action(s) Seller, in addition to any other rights it may have, will have

the right to purchase Buyer's Plant as its then fair market value.  If

Seller does exercise this option to purchase the Plant, Buyer shall have

the right to require Seller to also purchase the Site for fair market

value, if such Site is not then owned by Seller.  Fair market value shall

be established by appraisal by the American Appraisal Company (or similar

organization).  The provisions set forth in Article 18 shall be utilized to

settle any dispute as regards fair market value.



     16.4 Remedies Upon Default by Seller.



     Upon the occurrence of an Event of Default by Seller, Buyer may

exercise one or the other of the following options:  (i) Exercise all

remedies available at law or at equity or through other appropriate private

proceedings including, but not limited to, bringing an action or actions

from time to time for recovery of amounts due and unpaid by Seller, and/or

for damages and expenses resulting from the Event of Default, which shall

include all costs and expenses reasonably incurred in the exercise of its

remedies (including reasonable attorneys' fees), and/or specific

performance, Seller acknowledges and agrees that a breach by Seller

hereunder is likely to result in the curtailment by Buyer of its production

at the Plant, which will result in the loss of income to Buyer if Buyer

would have operated at full capacity had Seller delivered the steam which

it is required to deliver pursuant hereto.  Seller further acknowledges and

agrees that the damages which Buyer shall be entitled to recover pursuant

to



                              44







this paragraph include but are not limited to any income which it lost as a

result of the occurrence of an Event of Default by Seller; or (ii) Collect

Specified Damages from Seller upon submission of reasonable documentation

with respect to their incurrence, without resorting to legal process.

Specified Damages owed to Buyer pursuant to this Section shall be paid by

Seller no later than ten (10) days after submission by Buyer to Seller of

reasonable documentation with respect to their incurrence.  Seller's

failure to pay such damages to Buyer shall entitle Buyer to exercise any,

all or some of the remedies specified in clause (i) above.



     In the event that either (a) Buyer elects option (i) above or (b)

elects option (ii) above but fails to collect Specified Damages with ten

(10) days demand therefor, buyer may purchase the Cogeneration Facility and

the Site (if not then owned by Buyer) at their then fair market value in

accordance with Section 5.2 hereof.  In addition, in either such event,

Buyer shall enjoy a right of first refusal with respect to the Cogeneration

Facility, and the Site (if then owned by Seller) and Seller shall give

Buyer ninety (90) days' written notice of any offer which notice shall

specify the terms and conditions of the proposed sale.  Buyer shall have

the right, exercisable within thirty (30) days of receipt of said notice,

but not the obligation, to purchase the Cogeneration Facility, and the Site

(if applicable) on the terms and conditions specified in the notice.



     16.5 Remedies.



     Except as specifically limited in this Agreement, each



                              45







and every right, power and remedy of a Party, whether specifically stated

in this Agreement or otherwise existing, may be exercised from time to time

and so often and in such order as may be deemed expedient by the exercising

Party, and the exercise or the beginning of the exercise of any right,

power or remedy shall not be deemed a waiver of the right to exercise, at

the same time or thereafter, any other right, power or remedy.  No delay or

omission of a Party in the exercise of any right, power or remedy shall

impair or operate as a waiver thereof or of any other right, power or

remedy then or thereafter existing.



     16.6 Fair Market Value.



     If Buyer exercises its option under Section 5.2, the fair market value

of the Cogeneration Facility and the Site (if applicable) shall be

determined as of the time immediately before the Event of Default or option

by appraisal of the American Appraisal Company (or similar appraisal

organization).  The arbitration provisions set forth in Article 18 shall be

utilized to settle any dispute as regards "fair market value".

     Buyer recognizes that Seller will be obtaining financing to construct

the Cogeneration Facility from one or more financial institutions and

hereby agrees to provide Seller with any documents and records Seller may

reasonably request in connection with Seller's efforts to obtain financing.

Buyer agrees to provide financial statements to the extent that they are

available but shall not be required to provide copies of its tax returns.



                              46







     Seller recognizes that Buyer has granted mortgages on the Plant and

land associated therewith.  Buyer covenants and agrees to use its best

efforts to obtain an amendment to such mortgage allowing it to lease the

Site to Seller pursuant to the terms hereof.  In the event that Buyer fails

to _______ an amendment on the mortgage granted to First Fidelity Bank,

N.A., New Jersey, it shall be relieved from any and all liability

hereunder.  Seller's rights to purchase the Plant pursuant to the terms of

this Agreement shall be subject to and subordinate to any rights granted to

mortgagees in such mortgages.

or the breach thereof, shall be settled by arbitration in Philadelphia,

Pennsylvania, by a panel of three arbitrators in accordance with the Rules

of the American Arbitration Association, and judgment upon the award

rendered may be entered in any court having jurisdiction thereof.  The

expenses of the arbitration shall be borne by the unsuccessful Party unless

the arbitration award shall otherwise provide.

     Except as herein provided to the contrary, the rights and duties of

Buyer and Seller under this Agreement are not assignable or delegable by

either Party without the express written consent of the other, which

consent will not be unreasonably withheld.  Buyer and Seller may each

mortgage, hypothecate,



                              47







pledge or encumber its interest in this Agreement, and, in the case of the

Seller, in the Cogeneration Facility and Site if then owned by Seller, to

any financial institution lending funds for construction or improvement of

the Plant or the Cogeneration Facility.



     This Agreement is binding on all of Buyer's and Seller's respective

successors and assignees.
