encumbrance  created  hereby,  by  the  Borrower  Bond,  by  the  Borrower  Bond
Resolution and by any other  outstanding  debt  obligations of the Borrower that
are at parity with the Borrower  Bond as to lien on, and source and security for
payment   thereon   from,   the   revenues  of  the   Borrower's   Environmental

observance and performance by the Borrower of its duties, covenants, obligations
and  agreements  under this Loan  Agreement  and the  Borrower  Bond and for the
undertaking  or  completion  of the Project  and the  financing  or  refinancing
thereof,  including, but not limited to, the approval by the New Jersey Board of
Public  Utilities  (the "BPU") of the  issuance by the  Borrower

     (financial   or   otherwise)   of  the   Borrower   or  its   Environmental
     Infrastructure System; and

          (ii)  has  obtained  all  licenses,   permits,   franchises  or  other
     governmental  authorizations  presently  necessary for the ownership of its

                                   ARTICLE III

              LOAN TO BORROWER; AMOUNTS PAYABLE; GENERAL AGREEMENTS

     SECTION 3.01.  Loan; Loan Term. The State hereby agrees to make the Loan as
described  in Exhibit  A-2 hereof and to  disburse  proceeds  of the Loan to the
Borrower in accordance with Section 3.02 and Exhibit C hereof,  and the Borrower
hereby  agrees to borrow  and  accept the Loan from the State upon the terms set
forth in Exhibit A-2 attached hereto and made a part hereof; provided,  however,
that the State shall be under no  obligation to make the Loan if (a) at the Loan
Closing,  the  Borrower  does not deliver to the State a Borrower  Bond and such
other  documents  required  under  Section  2.02(l)  hereof,  or (b) an Event of
Default has occurred and is continuing  under this Loan Agreement.  Although the
State intends to disburse  proceeds of the Loan to the Borrower at the times and
up to the  amounts  set forth in  Exhibit C to pay a portion  of the Cost of the
Project,  due to unforeseen  circumstances  there may not be sufficient  Federal
Funds  on  deposit  on any  date  to  make  the  disbursement  in  such  amount.
Nevertheless,  the Borrower agrees that the aggregate principal amount set forth
in Exhibit A-2 hereto shall constitute the initial  principal amount of the Loan
(as the  same  may be  adjusted  downward  in  accordance  with  the  definition
thereof),  and  the  State  shall  have no  obligation  thereafter  to loan  any
additional amounts to the Borrower.

     The Borrower shall have no legal or equitable interest in the Federal Funds
received by and  available  to the State or in moneys from  repayments  of loans
previously made from Federal Funds by the State.

     The Borrower shall use the proceeds of the Loan strictly in accordance with
Section 2.01(h) hereof.

     The  payment   obligations  created  under  this  Loan  Agreement  and  the
obligations  to pay the  principal  of and other  amounts due under the Borrower
Bond are each direct, general,  irrevocable and unconditional obligations of the
Borrower payable from any source legally available to the Borrower in accordance
with the terms of and to the extent provided in the Borrower Bond Resolution.

     SECTION 3.02.  Disbursement of Loan Proceeds.  (a) The State shall disburse
Federal  Funds  earmarked  for the Loan to the Borrower in  accordance  with the
terms hereof.  Before each and every disbursement of the proceeds of the Loan by
the State to the Borrower,  the Borrower shall in accordance with the procedures
set forth in the  Regulations  submit to the State a requisition  executed by an
Authorized Officer of the Borrower.

     (b) The State  shall  not be under  any  obligation  to  disburse  any Loan
proceeds to the Borrower under this Loan Agreement, unless:

          (i) the Loan  Closing  shall  have  occurred  on the date  established
     therefor by the State;

          (ii) there shall be Federal Funds  available from time to time to fund
     the Loan, as 


                                      -13-


     determined solely by the State;

          (iii) in accordance with the "New Jersey Environmental  Infrastructure
     Trust Act", P.L. 1985, c. 334, as amended (N.J.S.A.  58:11B-1 et seq.), and
     the  Regulations,  the Borrower  shall have timely  applied for, shall have
     been awarded and, prior to or simultaneously  with the Loan Closing,  shall
     have closed a Trust Loan for a portion of the  Allowable  Costs (as defined
     in such  regulations)  of the  Project  in an  amount  not in excess of the
     amount  of  Allowable  Costs of the  Project  covered  by the Loan from the
     State,  plus the amount of: (i)  capitalized  interest  during the  Project
     construction  period, if any, (ii) the cost of funding reserve capacity for
     the Project,  if any, as well as that  portion of the Debt Service  Reserve
     Fund (as defined in the Trust Loan  Agreement)  attributable to the cost of
     funding such reserve  capacity for the Project,  and (iii) certain issuance
     expenses  related  thereto,  including,  if  applicable,  a municipal  bond
     insurance policy premium;

          (iv) the Borrower  shall have on hand moneys to pay for the greater of
     (A) that  portion of the total cost of the Project  that is not eligible to
     be funded from the Loan or the Trust Loan, or (B) that portion of the total
     cost of the Project that exceeds the actual amounts of the loan commitments
     made by the State and the Trust,  respectively,  for the Loan and the Trust
     Loan; and

          (v) no Event of Default nor any event  that,  with the passage of time
     or service of notice or both,  would  constitute  an Event of Default shall
     have occurred and be continuing hereunder.

     SECTION 3.03.  Amounts  Payable.  (a) The Borrower  shall repay the Loan at
zero-interest   in  principal   installments   payable  to  the  Loan   Servicer
semiannually  on  February  1 and  August  1,  commencing  August  1,  1999,  in
accordance with the schedule set forth in Exhibit A-2 attached hereto and made a
part hereof, as the same may be amended or modified by the State, in particular,
without  limitation,  to make  any  adjustments  to the  amount  of the  Loan in
accordance with the definition thereof;  provided,  however,  that the amount of
any reduction in the principal amount of the Loan pursuant to N.J.A.C. 7:22-3.26
shall be credited to the principal  payments set forth in Exhibit A-2 in inverse
order of their maturity. The obligations of the Borrower under the Borrower Bond
shall be deemed to be amounts payable under this Section 3.03. Each payment made
to the Loan  Servicer  pursuant  to the  Borrower  Bond  shall be deemed to be a
credit against the  corresponding  obligation of the Borrower under this Section
3.03,  and any  such  payment  made  to the  Loan  Servicer  shall  fulfill  the
Borrower's  obligation to pay such amount hereunder and under the Borrower Bond.
Each  payment made to the Loan  Servicer  pursuant to this Section 3.03 shall be
applied to the principal of the Loan.

     (b)  In  addition  to  the  principal  payments  on the  Loan  required  by
subsection  (a) of this Section 3.03,  the Borrower  shall pay a late charge for
any such  payment  that is  received by the Loan  Servicer  later than the tenth
(10th) day  following  its due date in an amount  equal to the greater of twelve
percent (12%) per annum or the Prime Rate plus one half of one percent per annum
on such late  payment  from its due date to the date  actually  paid;  provided,
however, that such late charge payable on the Loan shall not be in excess of the
maximum interest rate permitted by law.



                                      -14-


     (c) In addition to the Loan  Repayments  payable under  subsections (a) and
(b) of this Section 3.03, the Borrower shall pay one-half of the  Administrative
Fee, if any, to the Loan Servicer  semiannually on each February 1 and August 1,
commencing  February 1, 1999 or such later date as the State authorizes,  during
the term of the Loan.

     SECTION 3.04. Unconditional Obligations.  The obligation of the Borrower to
make the Loan  Repayments  and all other  payments  required  hereunder  and the
obligation to perform and observe the other duties,  covenants,  obligations and
agreements on its part contained herein shall be absolute and unconditional, and
shall not be abated, rebated, set-off, reduced, abrogated,  terminated,  waived,
diminished,  postponed  or  otherwise  modified  in any  manner or to any extent
whatsoever while any Loan Repayments remain unpaid,  for any reason,  regardless
of any contingency,  act of God, event or cause whatsoever,  including  (without
limitation)  any  acts  or   circumstances   that  may  constitute   failure  of
consideration,  eviction or constructive  eviction, the taking by eminent domain
or  destruction  of or damage to the  Project  or  Environmental  Infrastructure
System,  commercial  frustration  of the purpose,  any change in the laws of the
United  States  of  America  or of the  State  of New  Jersey  or any  political
subdivision  of  either  or in the  rules  or  regulations  of any  governmental
authority,  any  failure  of the State to perform  and  observe  any  agreement,
whether express or implied, or any duty,  liability or obligation arising out of
or connected with the Project or this Loan Agreement,  or any rights of set-off,
recoupment,  abatement or  counterclaim  that the Borrower might  otherwise have
against the State,  the Loan  Servicer or any other party or parties;  provided,
however,  that  payments  hereunder  shall not  constitute  a waiver of any such
rights.  The Borrower shall not be obligated to make any payments required to be
made by any other Borrowers under separate Loan Agreements.

     SECTION 3.05.  Loan  Agreement to Survive Loan.  The Borrower  acknowledges
that its duties,  covenants,  obligations  and  agreements set forth in Sections
3.06(a) and (b) hereof shall survive the payment in full of the Loan.

     SECTION  3.06.  Disclaimer  of  Warranties  and  Indemnification.  (a)  The
Borrower  acknowledges and agrees that: (i) the State does not make any warranty
or  representation,  either  express  or  implied,  as  to  the  value,  design,
condition,  merchantability or fitness for particular purpose or fitness for any
use of the  Environmental  Infrastructure  System or the Project or any portions
thereof or any other warranty or representation with respect thereto; (ii) in no
event shall the State or its agents be liable or responsible for any incidental,
indirect,  special or consequential damages in connection with or arising out of
this Loan Agreement or the Project or the existence, furnishing,  functioning or
use of the  Environmental  Infrastructure  System or the  Project or any item or
products or services  provided for in this Loan Agreement;  and (iii) during the
term of this Loan  Agreement  and to the fullest  extent  permitted  by law, the
Borrower shall indemnify and hold the State harmless  against,  and the Borrower
shall pay any and all, liability, loss, cost, damage, claim, judgment or expense
of any and all kinds or nature and however arising and imposed by law, which the
State may  sustain,  be subject to or be caused to incur by reason of any claim,
suit or action based upon personal injury, death or damage to property,  whether
real, personal or mixed, or upon or arising out of contracts entered into by the
Borrower, the Borrower's ownership of the Environmental Infrastructure System or
the Project, or the acquisition, construction or installation of the Project.



                                      -15-


     (b) It is mutually  agreed by the Borrower and the State that the State and
its commissioners,  officers,  agents, servants or employees shall not be liable
for, and shall be  indemnified  and saved  harmless by the Borrower in any event
from,  any action  performed  under this Loan Agreement and any claim or suit of
whatsoever  nature,  except in the event of loss or damage  resulting from their
own negligence or willful misconduct.

     (c) In connection  with its  obligation  to provide the insurance  required
under Section  2.02(j)  hereof:  (i) the Borrower shall include,  or cause to be
included,  the  State  and its  employees  and  officers  as  additional  "named
insureds" on (A) any certificate of liability insurance procured by the Borrower
(or other similar document  evidencing the liability insurance coverage procured
by the Borrower) and (B) any certificate of liability  insurance procured by any
contractor or subcontractor for the Project,  and from the latter of the date of
the Loan Closing or the date of the  initiation of  construction  of the Project
until  the date  the  Borrower  receives  the  written  certificate  of  Project
completion from the State, the Borrower shall maintain said liability  insurance
covering the State and said  employees and officers in good  standing;  and (ii)
the Borrower  shall  include the State as an additional  "named  insured" on any
certificate of insurance  providing against risk of direct physical loss, damage
or destruction of the Environmental  Infrastructure  System, and during the Loan
Term the  Borrower  shall  maintain  said  insurance  covering the State in good
standing.

     The  Borrower  shall  provide  the  State  with a copy of each of any  such
original,  supplemental,  amendatory or reissued  certificates  of insurance (or
other similar documents  evidencing the insurance coverage) required pursuant to
this Section 3.06(c).

     SECTION 3.07. Option to Prepay Loan Repayments. The Borrower may prepay the
Loan Repayments, in whole or in part, upon not less than ninety (90) days' prior
written notice to the State;  provided,  however,  that any such full or partial
prepayment  may only be made (i) if the  Borrower  is not then in arrears on its
Trust Loan, (ii) if the Borrower is  contemporaneously  making a full or partial
prepayment of the Trust Loan such that, after the prepayment of the Loan and the
Trust Loan, the Trust gives its consent required under Section  3.07(iii) of the
Trust Loan  Agreement,  and (iii) upon the prior written  approval of the State.
Prepayments  shall be applied to the  principal  payments  on the portion of the
Loan to be prepaid in inverse order of their maturity.

     SECTION  3.08.  Priority of Loan and Trust Loan.  (a) The  Borrower  hereby
acknowledges that, to the extent allowed by law, including,  without limitation,
the  appropriations  act of the New Jersey  State  Legislature  authorizing  the
expenditure  of Trust  bond  proceeds  to  finance a portion  of the Cost of the
Project,  or the Borrower  Bond  Resolution,  any loan  repayments  then due and
payable  on the  Borrower's  Trust  Loan,  including,  without  limitation,  any
administrative  fees and any late payment charges then due and payable under the
Trust Loan  Agreement,  shall be satisfied by the Loan Servicer  before any Loan
Repayments then due and payable  hereunder on the Loan shall be satisfied by the
Loan Servicer.  The Borrower agrees not to interfere with any such action by the
Loan Servicer.

     (b) The Borrower hereby  acknowledges  that in the event the Borrower fails
or is unable to pay  promptly  to the Trust in full any loan  repayments  on the
Trust Loan,  then to the extent allowed by law any Loan  Repayments  paid by the
Borrower on the Loan under this Loan


                                      -16-


Agreement  and  received by the Loan  Servicer  during the time of any such loan
repayment  deficiency  under the Trust Loan Agreement  shall first be applied by
the Loan Servicer to satisfy such Trust Loan Agreement loan repayment deficiency
as a credit against the  obligations of the Borrower to make loan  repayments of
that portion of interest under the Trust Loan Agreement that is allocable to the
interest payable on the Trust Bonds (as defined in the Trust Loan Agreement) and
to make  payments  of that  portion  of  interest  under the bond  issued by the
Borrower to the Trust that is  allocable  to the  interest  payable on the Trust
Bonds,  second,  to the extent  available,  to make loan repayments of principal
under the Trust Loan  Agreement  and payments of principal on the bond issued by
the Borrower to the Trust pursuant to the Trust Loan  Agreement,  third,  to the
extent  available,  to the payment of the  administrative  fee payable under the
Trust Loan  Agreement and to make payments of that portion of interest under the
bond issued by the Borrower to the Trust that is allocable to the administrative
fee payable under the Trust Loan Agreement,  fourth, to the extent available, to
the payment of late charges  payable under the Trust Loan  Agreement and to make
payments of that  portion of interest  under the bond issued by the  Borrower to
the Trust that is  allocable to the late  charges  payable  under the Trust Loan
Agreement, and, finally, to the extent available, to make Loan Repayments on the
Loan.

     (c) The Borrower hereby further  acknowledges that any Loan Repayments paid
by the  Borrower  on the Loan under  this Loan  Agreement  shall be applied  (i)
according  to  Section  3(c) of the Loan  Servicing  and  Trust  Bonds  Security
Agreement  (as  defined in the  definition  of Loan  Servicer  herein)  and (ii)
according to the provisions of the Master Program Trust Agreement.

correctable but cannot be corrected within the applicable  period, the State may
not  unreasonably  withhold  its consent to an  extension of such time up to 120
days from the  delivery of the written  notice  referred to above if  corrective

possession continues for more than thirty (30) days;

     (e) the Borrower shall generally fail to pay its debts as such debts become

     SECTION 5.02.  Notice of Default.  The Borrower shall give the State prompt
telephonic  notice of the  occurrence  of any Event of  Default  referred  to in
Section  5.01(d)  or (e)  hereof  and of the  occurrence  of any other  event or
condition  that  constitutes  an Event of  Default  at such  time as any  senior
administrative  or  financial  officer  of the  Borrower  becomes  aware  of the
existence thereof.

     SECTION 5.03. Remedies on Default. Whenever an Event of Default referred to
in Section 5.01 hereof shall have  occurred and be  continuing,  the State shall
have the right to take whatever action at law or in equity may appear  necessary
or  desirable  to collect  the  amounts  then due and  thereafter  to become due
hereunder or to enforce the  observance and  performance of any duty,  covenant,
obligation or agreement of the Borrower hereunder.

     In addition,  if an Event of Default  referred to in Section 5.01(a) hereof
shall have occurred and be continuing, the State shall, to the extent allowed by
applicable  law,  have the right to declare  all Loan  Repayments  and all other
amounts  due  hereunder  (including,  without  limitation,  payments  under  the
Borrower  Bond)  to be  immediately  due and  payable,  and upon  notice  to the
Borrower the same shall become due and payable without further notice or demand.

     SECTION 5.04.  Attorneys'  Fees and Other  Expenses.  The Borrower shall on
demand pay to the State the reasonable  fees and expenses of attorneys and other

enforcement of the  observation  or performance of any other duties,  covenants,
obligations or agreements of the Borrower upon an Event of Default.

     SECTION  5.05.  Application  of Moneys.  Any moneys  collected by the State

attorneys'  fees or other fees and  expenses  owed by the  Borrower  pursuant to
Section 5.04 hereof,  (b) second, to the extent available,  to pay principal due
and payable on the Loan, (c) third,  to the extent  available,  to pay any other

conferred  upon or reserved to the State is intended to be exclusive,  and every
such remedy shall be  cumulative  and shall be in addition to every other remedy
given  under  this Loan  Agreement  or now or  hereafter  existing  at law or in
equity.  No delay or omission to exercise  any right,  remedy or power  accruing

                        SEE IMPORTANT NOTE ON PRIOR PAGE

     FOR VALUE RECEIVED, Middlesex Water Company, a corporation duly created and
validly existing under the Constitution and laws of the State of New Jersey (the
"Borrower"), hereby promises to pay to the order of the State of New Jersey (the
"State")  the   principal   amount  of  One  Million  Fifty   Thousand   Dollars
($1,050,000),  or such lesser amount as shall be  determined in accordance  with
Section 3.01 of the Loan Agreement (as hereinafter defined), at the times and in
the amounts determined as provided in the Loan Agreement, plus any other amounts
due and owing  under the Loan  Agreement  at the  times  and in the  amounts  as
provided therein. The Borrower irrevocably pledges its full faith and credit for
the punctual payment of the principal of, and all other amounts due under,  this
Borrower Bond and the Loan Agreement according to their respective terms.

     This Borrower  Bond is issued  pursuant to the Loan  Agreement  dated as of
November 1, 1998 by and between the State,  acting by and through the New Jersey
Department of Environmental Protection, and the Borrower (the "Loan Agreement"),
and is issued in  consideration  of the loan made thereunder (the "Loan") and to
evidence the payment  obligations  of the Borrower set forth in Section  3.03(a)
thereof.  Payments under this Borrower Bond shall,  except as otherwise provided
in the Loan Agreement,  be made directly to the Loan Servicer (as defined in the
Loan  Agreement) for the account of the State.  This Borrower Bond is subject to
assignment or  endorsement in accordance  with the terms of the Loan  Agreement.
All of the terms,  conditions  and provisions of the Loan Agreement are, by this
reference thereto, incorporated herein as part of this Borrower Bond.

     Pursuant to the Loan Agreement, disbursements shall be made by the State to
the  Borrower  upon  receipt  by the  State of  requisitions  from the  Borrower
executed and delivered in accordance with the  requirements set forth in Section
3.02 of the Loan Agreement.

     This  Borrower  Bond is  entitled  to the  benefits  and is  subject to the
conditions of the Loan  Agreement.  The  obligations of the Borrower to make the
payments  required  hereunder shall be absolute and  unconditional,  without any
defense or right of set-off, counterclaim or recoupment by reason of any default
by the State under the Loan Agreement or under any other  agreement  between the
Borrower and the State or out of any indebtedness or liability at any time owing
to the Borrower by the State or for any other reason.

     This  Borrower Bond is subject to optional  prepayment  under the terms and
conditions,  and in the amounts, provided in Section 3.07 of the Loan Agreement.
To the extent  allowed by  applicable  law, this Borrower Bond may be subject to
acceleration  under the terms and  conditions,  and in the amounts,  provided in
Section 5.03 of the Loan Agreement.

     To the extent provided by law, this Borrower Bond is junior and subordinate
in all respects to any bonds of the Borrower issued on even date herewith to the
New  Jersey  Environmental  Infrastructure  Trust as to lien on,  and source and
security for payment from, the revenues of the Borrower.



                                       D-3



     IN WITNESS  WHEREOF,  the Borrower has caused this Borrower Bond to be duly
executed, sealed and delivered as of this 15th day of October, 1998.

                                                              November 5, 1998

State of New Jersey
Department of Environmental Protection
401 East State Street
Trenton, New Jersey  08625

Ladies and Gentlemen:

     We have acted as counsel to Middlesex  Water  Company,  a corporation  duly
organized  and validly  existing  under the laws of the State of New Jersey (the
"Borrower"),  which has entered into a Loan Agreement (as  hereinafter  defined)
with the State of New Jersey, acting by and through the New Jersey Department of
Environmental  Protection  (the  "State"),  and have acted as such in connection
with the authorization,  execution,  attestation and delivery by the Borrower of
its Loan Agreement and Borrower Bond (as  hereinafter  defined)  pursuant to the
New Jersey  Business  Corporation  Act,  P.L.  1968,  c. 263,  as  amended  (the
"Business  Corporation Law"), and an indenture of the Borrower dated as of April
1, 1927 and  entitled  "Indenture  of  Mortgage",  as amended and  supplemented,
including by a supplemental  indenture dated as of November 1, 1998 and entitled
"Twenty-Third  Supplemental  Indenture"  (such  indentures shall be collectively
referred  to herein as the  "Resolution").  All  capitalized  terms used but not
defined  herein  shall  have the  meanings  ascribed  to such  terms in the Loan
Agreement.

     In so acting,  we have examined the  Constitution  and laws of the State of
New Jersey, including, without limitation, the Business Corporation Law, and the
certificate of incorporation and by-laws of the Borrower.  We have also examined
originals,  or copies certified or otherwise identified to our satisfaction,  of
the following:

     (a) the Loan Agreement dated as of November 1, 1998 (the "Loan  Agreement")
by and between the State and the Borrower;

     (b) the  proceedings of the board of directors of the Borrower  relating to
the approval of the Loan Agreement and the execution,  attestation  and delivery
thereof on behalf of the Borrower and the  authorization  of the undertaking and
completion of the Project;

     (c) the Borrower  Bond dated as of October 15, 1998 (the  "Borrower  Bond")
issued by the Borrower to the State to evidence the Loan; and

     (d) the proceedings  (together with the  proceedings  referred to in clause
(b) above and Section 5 below, the  "Proceedings")  of the board of directors of
the Borrower,  including,  without limitation,  the Resolution,  relating to the
authorization  of the  Borrower  Bond  and  the  sale,  execution,  attestation,
authentication  and delivery  thereof to the State (the Loan  Agreement  and the
Borrower Bond are referred to herein collectively as the "Loan Documents").



                                      E-2



     We have also  examined and relied upon  originals,  or copies  certified or
otherwise authenticated to our satisfaction,  of such other records,  documents,
certificates and other  instruments,  and have made such investigation of law as
in our judgment we have deemed necessary or appropriate,  to enable us to render
the opinions expressed below.

     We are of the opinion that:

     1. The Borrower is a corporation  duly created and validly  existing  under
and  pursuant  to the  Constitution  and  statutes  of the State of New  Jersey,
including  the Business  Corporation  Law,  with the legal right to carry on the
business of its Environmental Infrastructure System as currently being conducted
and as proposed to be conducted.

     2. The Borrower has full legal right and  authority to execute,  attest and
deliver the Loan Documents, to sell the Borrower Bond to the State, to cause the
authentication  of the  Borrower  Bond,  to  observe  and  perform  its  duties,
covenants,  obligations and agreements under the Loan Documents and to undertake
and complete the Project.

     3. The acting officials of the Borrower who are contemporaneously  herewith
performing  or have  previously  performed any action  contemplated  in the Loan
Agreement  are,  and at the time any such action was  performed  were,  the duly
appointed  or elected  officials of the Borrower  empowered  by  applicable  New
Jersey law and authorized by resolution of the Borrower to perform such actions.

     4. In  accordance  with  the  terms  of the  Resolution  and to the  extent
provided therein, the Borrower has irrevocably pledged its full faith and credit
for the punctual  payment of the Loan Repayments and all other amounts due under
the Loan Documents according to their respective terms.

     5. The  proceedings of the Borrower's  board of directors (i) approving the
Loan Documents,  (ii) authorizing  their execution,  attestation and delivery on
behalf  of  the  Borrower,  (iii)  with  respect  to  the  Borrower  Bond  only,
authorizing  its  sale  by  the  Borrower  to  the  State  and  authorizing  its
authentication  on behalf of the  Borrower,  (iv)  authorizing  the  Borrower to
consummate the transactions  contemplated by the Loan Documents, (v) authorizing
the Borrower to undertake  and complete the Project,  and (vi)  authorizing  the
execution  and delivery of all other  certificates,  agreements,  documents  and
instruments in connection  with the execution,  attestation  and delivery of the
Loan  Documents,  have each been duly and  lawfully  adopted and  authorized  in
accordance  with  applicable  law and  applicable  resolutions  of the Borrower,
including,  without  limitation,  the Resolution,  the other Proceedings and the
Business  Corporation  Law,  which  Proceedings  constitute  all of the  actions
necessary to be taken by the Borrower to authorize its actions  contemplated  by
clauses  (i)  through  (vi)  above and  which  Proceedings,  including,  without
limitation, the Resolution,  were duly adopted in accordance with applicable New
Jersey law at a meeting or  meetings  duly  called and held in  accordance  with
applicable  New  Jersey  law  and at  which  quorums  were  present  and  acting
throughout.



                                      E-3


     6. The Loan Documents  have been duly  authorized,  executed,  attested and
delivered by the Authorized Officers of the Borrower, the Borrower Bond has been
duly sold by the  Borrower  to the State,  and the  Borrower  Bond has been duly
authenticated by the trustee or paying agent under the Resolution;  and assuming
in the case of the Loan  Agreement  that the State has the  requisite  power and
authority to authorize,  execute,  attest and deliver,  and has duly authorized,
executed,  attested  and  delivered,  the Loan  Agreement,  the  Loan  Documents
constitute the legal, valid and binding obligations of the Borrower, enforceable
against  the  Borrower  in  accordance  with their  respective  terms,  subject,
however,  to the effect of, and to restrictions  and  limitations  imposed by or
resulting from,  bankruptcy,  insolvency,  moratorium,  reorganization  or other
similar laws affecting creditors' rights generally. No opinion is rendered as to
the availability of any particular remedy.

     7. The  authorization,  execution,  attestation  and  delivery  of the Loan
Documents  by the  Borrower  and,  in the case of the  Borrower  Bond only,  the
authentication  thereof by the trustee or paying agent under the  Resolution and
the sale thereof to the State,  the  observation and performance by the Borrower
of  its  duties,   covenants,   obligations  and  agreements   thereunder,   the
consummation of the transactions  contemplated  therein, and the undertaking and
completion of the Project do not and will not (i) other than the lien, charge or
encumbrance  created by the Loan  Documents,  by the Resolution and by any other
outstanding  debt  obligations  of the  Borrower  that  are at  parity  with the
Borrower  Bond as to lien on, and source and security for payment  thereon from,
the revenues of the Borrower,  result in the creation or imposition of any lien,
charge or encumbrance upon any properties or assets of the Borrower pursuant to,
(ii) result in any breach of any of the terms,  conditions or provisions  of, or
(iii) constitute a default under, any existing  resolution,  outstanding debt or
lease  obligation,  trust agreement,  indenture,  mortgage,  deed of trust, loan
agreement or other  instrument  to which the Borrower is a party or by which the
Borrower,  its Environmental  Infrastructure  System or any of its properties or
assets  may be  bound,  nor will such  action  result  in any  violation  of the
provisions of the charter or other  document  pursuant to which the Borrower was
established or any laws, ordinances,  injunctions,  judgments,  decrees,  rules,
regulations or existing orders of any court or  governmental  or  administrative
agency,   authority  or  person  to  which  the  Borrower,   its   Environmental
Infrastructure System or its properties or operations is subject.

     8. All approvals,  consents or  authorizations  of, or  registrations of or
filings with, any governmental or public agency, authority or person required to
date  on  the  part  of the  Borrower  in  connection  with  the  authorization,
execution, attestation, delivery and performance of the Loan Documents, the sale
of the Borrower Bond and the undertaking and completion of the Project have been
obtained or made.

     9. There is no litigation or other proceeding pending or, to our knowledge,
after due  inquiry,  threatened  in any  court or other  tribunal  of  competent
jurisdiction   (either   State  or  federal)  (i)   questioning   the  creation,
organization  or existence  of the  Borrower,  (ii)  questioning  the  validity,
legality or  enforceability  of the Resolution,  the Loan or the Loan Documents,
(iii)  questioning the undertaking or completion of the Project,  (iv) otherwise
challenging the Borrower's  ability to consummate the transactions  contemplated
by the Loan or the Loan Documents, or (v) that, if adversely decided, would have
a materially adverse impact on the financial condition of the Borrower.



                                      E-4


     10.  Other  than its bond dated as of October  15,  1998  issued to the New
Jersey Environmental  Infrastructure  Trust, the Borrower has no bonds, notes or
other debt  obligations  outstanding that are superior or senior to the Borrower
Bond as to lien on,  and source and  security  for  payment  thereof  from,  the
revenues of the Borrower.

     We hereby authorize McCarter & English,  LLP, acting as bond counsel to the
State in connection with the Loan, and the Attorney  General of the State of New
Jersey,  acting as general  counsel to the State in connection with the Loan, to

counterclaim  or recoupment by reason of any default by the State under the Loan
Agreement or under any other  agreement  between the Water Company and the State
or out of any  indebtedness  or liability at any time owing to the Water Company
by the State or for any other reason. The Series X Bond is subject to assignment

Indentures or in the Loan Agreement,  shall occur, the principal of the Series X

     As provided in the Mortgage as modified,  amended and  supplemented  by the
Supplemental  Indentures,  and subject to the limitations therein contained, the
Mortgage and all  indentures  supplemental  thereto may be modified,  amended or
supplemented  with the consent in writing of the holders of not less than 75% in
principal  amount of each series of Bonds  outstanding at the time and effective
upon the date all of the Series R Bonds are  retired or  defeased or the holders
thereof consent thereto,  with the consent in writing of the holders of not less

time;  provided,  however,  that no such modification shall reduce the principal
amount of a Bond or the premium, if any, payable on a redemption thereof, extend

thereon,  give a Bond any preference over another Bond,  create or permit a lien
on the property  subject to the Mortgage (other than a Permitted  Encumbrance as
defined in the Eighth  Supplemental  Indenture) prior to or on a parity with the
Mortgage,  or reduce  the  percentage  of the  holders  required  for any action
authorized to be taken by the holders of Bonds under the  Mortgage,  without the
consent of the  holders of all Bonds  affected by such  modification;  provided,
further, that no modification shall impose additional duties or responsibilities
on the Trustee without the consent of the Trustee.




                                       9


     The Mortgage  may be modified,  amended or  supplemented  by Water  Company
without the consent of the holders of the Bonds for one or more of the following
purposes: (1) to cure any ambiguity, supply any omission, or cure or correct any
defect or  inconsistent  provision in the Mortgage;  (2) to cure any  ambiguity,
supply any  omission  or cure or correct  any defect in any  description  of the
Mortgage Property, if such action is not adverse to the interests of the holders
of the Bonds;  (3) to insert such  provisions  clarifying  matters or  questions
arising  under the mortgage  indenture as are necessary or desirable and are not
contrary to or inconsistent with the Mortgage as in effect or (4) to restate the
Mortgage as supplemented by the Supplemental  Indentures as a single  integrated
document  which  may add  headings,  an index and other  provisions  aiding  the
convenience of use. The Company shall provide prior notice of such change to the
holders.



                                       10


     This  Series X Bond  shall not be  transferred  except (i) as  provided  or
required under and pursuant to the Loan Agreement, (ii) to effect an exchange in
connection with a bankruptcy, reorganization,  insolvency, or similar proceeding
involving  Water  Company  and (iii) to effect an exchange  in  connection  with
prepayment by  redemption or otherwise of the Series X Bond.  This Series X Bond
may be  transferred  at the principal  corporate  trust office of the Trustee by
surrendering  this  Series X Bond for  cancellation,  accompanied  by a  written
instrument  of  transfer  in  form  designated  by  the  holder  and  reasonably
acceptable to the Water Company and the Trustee, duly executed by the registered
owner  hereof in person or by attorney  duly  authorized  in  writing,  and upon
payment of any taxes or other  governmental  charges  incident to such transfer,
and upon any such transfer new  registered  Bond or Bonds of the same series and
of the same  aggregate  principal  amount in authorized  denominations,  will be
issued to the transferee in exchange herefor.

     This Series X Bond, upon surrender hereof to the Trustee,  accompanied by a
written  instrument  of  transfer as  aforesaid,  may be  exchanged  for another
registered  Bond of the same  series and of the same  principal  amount;  to the
extent  permitted  by the Loan  Agreement  and upon  payment of any  charges and
subject to the terms and conditions  set



                                       11

     The person in whose name this  Series X Bond shall be  registered  shall be
deemed the owner  hereof for all  purposes,  and payment of or on account of the
principal  hereof and interest hereon shall be made only to or upon the order in
writing of the registered owner hereof; and all such payments shall be valid and
effectual to satisfy and discharge the liability  upon this Series X Bond to the
extent of the sum or sums so paid.

     No recourse shall be had for the payment of the principal of or interest on
this Series X Bond or for any claim based hereon or otherwise in respect  hereof
or of  the  Mortgage  or of  any  indenture  supplemental  thereto  against  any
incorporator,  or against any stockholder,  director or officer,  as such, past,
present  or  future,  of  Water  Company  or of  any  predecessor  or  successor
corporation, either directly or through Water Company or any such predecessor or
successor corporation, whether by virtue of any constitution, statute or rule of
law or equity, or by the enforcement of any assessment or penalty,  or otherwise
howsoever, all such liability being, by the acceptance hereof and as part of the
consideration  for the issue  hereof,  expressly  waived and  released  by every
holder or


                                       12


registered  owner hereof as more fully provided in the Mortgage and Supplemental
Indentures;  it being  expressly  agreed and  understood  that the  Mortgage and
Supplemental  Indentures  and all Bonds  thereby  secured  are solely  corporate

     The terms and  provisions of the Series X Bond shall not be amended by, and
the Series X Bond shall not be entitled to the benefit of, any covenant, term or
condition contained in any subsequent supplemental indenture without the express
written concurrence of the Water Company.

     This Series X Bond shall not be entitled to any benefit  under the Mortgage
or any indenture  supplemental thereto, or be valid or become obligatory for any
purpose,  until First Union National Bank, as the Trustee under the Mortgage and
Supplemental Indentures, or its successor thereunder, shall have signed the form
of certificate endorsed hereon.
