Ladies and Gentlemen:

     Goldman,  Sachs & Co.,  BNY Capital  Markets,  Inc.,  Sovereign  Securities
Corporation,  LLC and The Williams  Capital Group,  L.P. (each, an "Underwriter"
and  collectively,  the  "Underwriters")  offer  to  enter  into  the  following
agreement  with New York State Energy  Research and  Development  Authority (the
"Authority")  and The Brooklyn Union Gas Company d/b/a KeySpan  Energy  Delivery
New York (the "Company"), which, upon acceptance of this Bond Purchase Agreement
(the "Bond  Purchase  Agreement")  by the Authority and by the Company,  will be
binding upon the Authority, the Company and the Underwriters. This offer is made
subject to acceptance  of this Bond Purchase  Agreement by the Authority and the
Company on or before 4:00 P.M. New York time on the date  hereof,  and if not so
accepted,  will  be  subject  to  withdrawal  by the  Underwriters  upon  notice
delivered to your  offices,  at any time prior to the  acceptance  hereof by the
Authority  and the Company.  Terms used in the Bond  Purchase  Agreement but not
defined  herein shall have the meanings  assigned to them in the  Indenture  (as
hereinafter defined).

1.       Background

     Per  the  request  of the  Company,  the  Authority  has  agreed  to  issue
$55,000,000  aggregate  principal  amount of Gas  Facilities  Revenue Bonds (The
Brooklyn Union Gas Company d/b/a KeySpan Energy Delivery New York Project), 2005
Series B (the "Bonds"), for the purpose of refunding the Authority's $55,000,000
outstanding  principal  amount of Gas Facilities  Revenue  Bonds,  Series C (The





Brooklyn Union Gas Company  Project) (the "Prior  Bonds").  The Prior Bonds were
previously  issued to  provide  all or part of the  funds  for the  acquisition,
construction,   and  installation  (or  any  combination   thereof)  of  certain
facilities for the local furnishing of gas.

     The Bonds shall be issued  under and secured by an indenture of trust dated
as of November 1, 2005 (the  "Indenture")  between the  Authority  and Citibank,
N.A.,  as trustee  (the  "Trustee"),  and pursuant to a bond  resolution  of the
Authority, Resolution No. 1094 adopted September 19, 2005 (the "Resolution"). In
connection  with the issuance of the Bonds,  the  Authority and the Company will
enter into a participation  agreement  related to the Bonds dated as of November
1, 2005 (the "Participation  Agreement")  pursuant to which the Company proposes
to  issue  a  promissory  note,  substantially  in  the  form  attached  to  the
Participation  Agreement,  to  evidence  the  obligation  of the  Company to the
Authority  to repay the  advance  of the  proceeds  of the Bonds  (the  "Company
Note").  In addition,  the Trustee will enter into an Auction  Agency  Agreement
(the  "Auction  Agreement"),  which the Company will  acknowledge  and agree to,
relating to the Bonds,  dated as of November 1, 2005,  with The Bank of New York
as Auction Agent (the "Auction Agent"),  providing, among other things, that the
Auction  Agent will  follow  certain  auction  procedures  (each  implementation
thereof, an "Auction") for the purpose of determining the rate of interest which
the  Bonds  will bear when such  rate is to be  determined  by an  Auction.  The
Company  and the  Auction  Agent will also  enter into a separate  Broker-Dealer
Agreement  with  respect to the Bonds with each of Goldman,  Sachs & Co. and BNY
Capital  Markets,   Inc.  (each,  a  "Broker-Dealer"   and   collectively,   the
"Broker-Dealers"),  each  dated  as  of  November  1,  2005  (collectively,  the
"Broker-Dealer  Agreements").  On the  Closing  Date (as  defined  in  Section 7
hereof),  the  Company  will  also  execute  a  Rule  15c2-12(b)(5)   continuing
disclosure  certificate,  dated the  Closing  Date  relating  to the Bonds  (the
"Company's Disclosure Certificate").  On and after the Closing Date, the payment
of the  regularly  scheduled  principal  of, and  interest on, the Bonds will be
insured by a municipal bond new issue insurance policy (the "Support  Facility",
or the "Insurance  Policy") issued by Financial  Guaranty Insurance Company (the
"Insurer").

     The Bonds will be limited  obligations of the Authority  payable solely out
of  revenues  or other  receipts,  funds or moneys  pledged  therefor  under the
Indenture or from the proceeds of the Support Facility.

     2. Purchase and Sale of Bonds.  Subject to the terms and conditions of this
Bond Purchase  Agreement,  on the Closing Date, the  Underwriters  will purchase
$55,000,000  aggregate principal amount of the Bonds from the Company at a price
of 100% of the principal amount thereof.  The Underwriters will be paid a fee of
$192,500 by the Company on the Closing Date.

     The Underwriters  will take up and pay for all of the Bonds to be purchased
by it if any are  taken.  The  Underwriters  will  initially  reoffer  the Bonds
purchased  by them to the public at a price of 100% of the par  amount  thereof.
The purchase will be made by the delivery of immediately available funds through
the facilities of The Depository Trust Company in New York, New York.

          fact necessary in order to make the statements made therein,  in light
          of the circumstances under which they were made, not misleading.

          Indenture,   the  Tax  Regulatory  Agreement,  and  the  Participation
          Agreement.

     (o)  Until the end of the  underwriting  period,  the Authority will advise

          if the Authority  believes that the Authority  Information is not true
          or correct,  contains any untrue or incorrect  statement or misleading
          statement  of a  material  fact or  omits  to  state a  material  fact
          necessary  in order to make the  statements  therein,  in light of the

               adverse effect on the market price of the Bonds; and

          (vii) There shall not have occurred any event that (i) makes untrue or

     (c)  The  marketability of the Bonds shall not, in the reasonable  judgment

               to rely thereon as though such  opinion  were  addressed to them,

               each case with such  changes  from such  respective  forms as the
               Underwriters shall approve;

          (10) An opinion or opinions,  dated the Closing Date, addressed to the
               Underwriters,  of Pillsbury Winthrop Shaw Pittman LLP, as counsel
               for the  Underwriters,  with respect to the issue and sale of the
               Bonds,  the Official  Statement and other related  matters as the
               Underwriters may require;

          (11) A  letter  from   Deloitte  &  Touche  LLP,   addressed   to  the

               is deemed acceptable by the Underwriters;


                                       17



          (14) Such additional certificates,  proceedings, opinions, instruments
               or documents as the  Underwriters or counsel to the  Underwriters
               may  reasonably  request  in  connection  with  the  transactions
               contemplated by this Bond Purchase Agreement.

          the Underwriters, by wire transfer of immediately available funds, the
          amounts representing the underwriting  commission specified in Section
          2 hereof in connection with the offering and sale of the Bonds.

     Delivery of the aforesaid documents shall be made at the offices of Hawkins
Delafield & Wood LLP, 67 Wall Street,  New York,  New York.  If the Authority or
the  Company  shall be  unable  to  satisfy  the  respective  conditions  to the
obligations of the Underwriters contained in this Bond Purchase Agreement, or if
the obligations of the Underwriters shall be terminated for any reason permitted
by this Bond Purchase Agreement,  the Underwriters may cancel this Bond Purchase
Agreement. Upon any such cancellation,  neither the Underwriters,  the Authority
nor the Company shall be under further  obligation  hereunder except as provided
in Sections 10 and 11 hereof.

     9. Supplements or Amendments to Official Statement.  The Authority will not
adopt any  amendment of or  supplement  to the  Official  Statement to which the
Underwriters  or the Company  shall  reasonably  object in  writing.  During the
underwriting  period,  if any  event  shall  occur  as a  result  of which it is
necessary, in the opinion of the Underwriters or counsel to the Underwriters, to
amend or  supplement  the  Official  Statement  so that it will not  contain any
untrue  statement of a material fact or omit to state a material fact  necessary
in order to make the statements  therein, in the light of the circumstances when
the Official Statement is delivered to a purchaser or a potential purchaser, not
misleading,  the Authority and the Company will cooperate, at the request of the
Underwriters, in the prompt preparation and delivery to the Underwriters, at the
Company's expense (or at the expense of the  Broker-Dealers if such amendment or
supplement is required to update the statements contained under the heading "THE
AUCTION  RATE  BONDS-Special  Considerations  Relating to the Auction Rate Bonds
Bearing  Interest at Auction Period  Rates--The  SEC is Reviewing  Broker-Dealer
Practices in the Market for Auction-Rate  Securities"),  of either amendments or
supplements  to the Official  Statement so that the  statements  in the Official
Statement  as so  amended  or  supplemented  will  not,  in  the  light  of  the
circumstances  when the  Official  Statement  is  delivered  to a purchaser or a
potential purchaser, be misleading.

     10. Expenses. The Underwriters shall be under no obligation to pay, and the
Company shall pay, any expenses  incident to the  performance of the obligations
of the Authority  and the Company under this Bond Purchase  Agreement and to the
sale and delivery of the Bonds to the Underwriters,  including,  but not limited
to: (i) the cost of the preparation  and printing of the Indenture,  the Auction
Agreement, the Broker-Dealer Agreement, the Remarketing Agreement, the Company's
Disclosure  Certificate,   the  Participation   Agreement,  the  Tax  Regulatory
Agreement,  the Company  Note,  the Official  Statement and any  supplements  or
amendments to either thereof, the Bonds and this Bond Purchase Agreement and all
other agreement and documents  contemplated hereby, (ii) the reasonable fees and
disbursements of Hawkins Delafield & Wood LLP, Bond Counsel, (iii) reimbursement


                                       18



to the Underwriters  for their  incremental  costs in arranging  payment for the
Bonds in immediately  available funds, (iv) the Bond Market  Association  filing
fee in connection with the Bonds, (v) any fees and  disbursements of the Trustee
and the Auction  Agent,  including  the  reasonable  fees and  disbursements  of
counsel to the Trustee and the Auction  Agent and (vi) the  reasonable  fees and
disbursements of counsel for the Underwriters,  including,  without  limitation,
those incurred in connection with the  qualification  of the Bonds for sale, and
the determination of their eligibility for investment, under the laws of various
jurisdictions  and the preparation of the Blue Sky Memorandum.  In the event the
Bonds  are  not  purchased  by the  Underwriters,  the  Company  shall  pay  the
reasonable fees and expenses of counsel to the  Underwriters  and the reasonable
fees and  disbursements  of Hawkins  Delafield  & Wood LLP,  Bond  Counsel.  The
Underwriters  shall pay (i) all  advertising  expenses  in  connection  with any
offering of the Bonds and (ii) all other  expenses  incurred by it in connection
with the offering and distribution of the Bonds.

     11. Indemnification.  (a) To the extent permitted by law, the Company shall
indemnify  and hold  harmless the  Authority,  any  Underwriters,  each of their
respective members, directors,  officers,  employees and agents and each person,
if any,  who controls the  Authority  or any  Underwriter  within the meaning of
Section 15 of the Securities Act against any and all losses,  claims, damages or
liabilities,  joint or  several,  to which  such  indemnified  party may  become
subject  under  any  statute  or at law or in  equity  or  otherwise,  and shall
reimburse any such indemnified party for any legal or other expenses  reasonably
incurred by it in  connection  with  investigating  any claims and defending any
actions, insofar as such losses, claims, damages,  liabilities or expenses arise
out of or are based upon any untrue  statement or alleged untrue  statement of a
material fact contained in the Official  Statement,  or in any amendment thereof
or supplement thereto, or arise out of or are based upon the omission or alleged
omission  to state  therein a material  fact  necessary  to make the  statements
therein  not  misleading,  except  insofar  as  such  losses,  claims,  damages,
liabilities  or expenses are caused by any such untrue  statement or omission or
alleged untrue statement or omission based upon the Authority  Information,  DTC
Information,  the Insurer Information, the Underwriters Information or under the
heading "TAX MATTERS" contained in the Official Statement.

     (b)  Each  Underwriter  agrees  severally  and not jointly to indemnify and
          hold harmless the  Authority,  the Company,  each of their  respective
          members,  directors,  officers and employees, and each person, if any,
          who  controls  the  Authority  or the  Company  within the  meaning of
          Section 15 of the  Securities  Act to the same extent as the foregoing
          indemnity from the Company to the Authority and the Underwriters,  but
          only insofar as losses, claims,  damages,  liabilities or expenses are
          caused by any untrue statement or omission or alleged untrue statement
          or omission based upon the Underwriters  Information  contained in the
          Official Statement, or in any amendment thereof or supplement thereto.

     (c)  Promptly after receipt by an indemnified party under subsection (a) or
          (b) of this  Section 11 of notice of the  commencement  of any action,
          and as a  condition  to  indemnification  under this  Section 11, such
          indemnified  party will,  if a claim in respect  thereof is to be made
          against the  indemnifying  party  hereunder,  notify the  indemnifying
          party in writing of the commencement  thereof;  but the omission so to
          notify the indemnifying  party will not relieve the indemnifying party
          from  any  liability  which  it  may  have  to any  indemnified  party


                                       19



          otherwise  than  under  this  Section  11. In case any such  action is
          brought   against  any   indemnified   party,   and  it  notifies  the
          indemnifying party of the commencement thereof, the indemnifying party
          will be entitled,  at its own expense, to participate  therein, and to
          the  extent  that it may  elect by  written  notice  delivered  to the
          indemnified  party promptly after receiving the aforesaid  notice from
          such indemnified  party, to assume the defense  thereof,  with counsel
          satisfactory to such  indemnified  party;  provided,  however,  if the
          defendants in any such action include both the  indemnified  party and
          the indemnifying party and the indemnified party shall have reasonably
          concluded  that  there may be legal  defenses  available  to it and/or
          other  indemnified  parties which are different  from or additional to
          those available to the indemnifying  party,  the indemnified  party or
          parties shall have the right to select separate counsel to assume such
          legal  defenses  and to otherwise  participate  in the defense of such
          action on behalf of such indemnified party or parties. Upon receipt of
          notice from the indemnifying  party to such  indemnified  party of its
          election so to assume the  defense of such action and  approval by the
          indemnified  party of  counsel,  the  indemnifying  party  will not be
          liable to such  indemnified  party under this Section 11 for any legal
          or other expenses  subsequently  incurred by such indemnified party in
          connection with the defense  thereof unless (i) the indemnified  party
          shall have employed such counsel in connection  with the assumption of
          legal  defenses in accordance  with the proviso to the next  preceding
          sentence (it being understood,  however,  that the indemnifying  party
          shall  not be  liable  for the  expenses  of more  than  one  separate
          counsel),  (ii) the indemnifying party shall not have employed counsel
          satisfactory  to the  indemnified  party to represent the  indemnified
          party within a reasonable  time after  notice of  commencement  of the
          action or (iii) the  indemnifying  party has authorized the employment
          of  counsel  for  the   indemnified   party  at  the  expense  of  the
          indemnifying party.

     (d)  If the  indemnification  provided for in this Section 11 is applicable
          in  accordance  with  its  terms  but  for  any  reason  is held to be
          unavailable to or insufficient  to hold an indemnified  party harmless
          under  subsection  (a) or (b) above in respect of any losses,  claims,
          damages or  liabilities  (or actions in respect  thereof)  referred to
          therein, then the Company and the Underwriters shall contribute to the
          amount paid or payable by such  indemnified  party as a result of said
          losses, claims, damages or liabilities (or actions in respect thereof)
          in such proportion as is appropriate to reflect the relative  benefits
          received  by the Company on the one hand and the  Underwriters  on the
          other from the offering of the Bonds to which said loss, claim, damage
          or liability (or action in respect thereof) relates.  If, however, the
          allocation  provided  by the  immediately  preceding  sentence  is not
          permitted by  applicable  law,  then the Company and the  Underwriters
          shall  contribute  to the amount  paid or payable by such  indemnified
          party in such  proportion as is  appropriate  to reflect not only such
          relative  benefits but also the  relative  fault of the Company on the
          one hand and the  Underwriters  on the  other in  connection  with the
          statements or omissions that resulted in said losses,  claims, damages
          or liabilities (or actions in respect  thereof),  as well as any other
          relevant equitable  considerations.  The relative benefits received by
          the Company on the one hand and the Underwriters on the other shall be


                                       20



          deemed to be in the same proportion as the total net proceeds from the
          offering (before  deducting  expenses) bear to the total  underwriting
          discounts and commissions  received by the Underwriters.  The relative
          fault shall be determined by reference to, among other things, whether
          the true or  allegedly  untrue  statement  of a  material  fact or the
          omission  or  alleged  omission  to state a material  fact  relates to
          information   supplied   by  the  Company  on  the  one  hand  or  the
          Underwriters on the other and the parties' relative intent, knowledge,
          access to  information  and  opportunity  to correct  or prevent  such
          statement or omission.  The Company and the Underwriters agree that it
          would  not be just and  equitable  if  contribution  pursuant  to this
          subsection (d) were  determined by pro rata allocation or by any other
          method of  allocation  which does not take  account  of the  equitable
          considerations  referred to above in this  subsection  (d). The amount
          paid or payable  by an  indemnified  party as a result of the  losses,
          claims,  damages  or  liabilities  (or  actions  in  respect  thereof)
          referred  to above in this  subsection  (d) shall be deemed to include
          any legal or other  expenses  reasonably  incurred by the  indemnified
          party in connection with investigating or defending any such action or
          claim.  Notwithstanding  the  provisions of this  subsection  (d), the
          Underwriters  shall not be required to contribute any amount in excess
          of the  amount by which the  underwriting  discounts  and  commissions
          received  by  it  exceeds   the  amount  of  any  damages   that  said
          Underwriters  has  otherwise  been  required  to pay by reason of said
          untrue or allegedly untrue statement or omission or alleged  omission.
          No person guilty of fraudulent  misrepresentation  (within the meaning
          of Section  11(f) of the Act) shall be entitled to  contribution  from
          any person who was not guilty of the fraudulent misrepresentation. The
          foregoing  provisions  regarding  contribution  shall apply  except as
          otherwise required by applicable law.

Ladies and Gentlemen:

     In connection with the issuance of $55,000,000  aggregate  principal amount
of Gas  Facilities  Revenue Bonds (The Brooklyn  Union Gas Company d/b/a KeySpan
Energy  Delivery New York  Project),  2005 Series B (the "Bonds")  issued by New
York State Energy Research and Development  Authority (the "Authority"),  a body
corporate and politic  constituting a public benefit  corporation created by the
State of New York,  which Bonds are being  purchased  by you  pursuant to a Bond
Purchase Agreement, dated October 26, 2005 (the "Bond Purchase Agreement"), with
the Authority and The Brooklyn Union Gas Company d/b/a KeySpan  Energy  Delivery
New York (the "Company"), we have examined:

     (a)  A copy of the Indenture of Trust dated as of November 1, 2005,  herein
          called the  "Indenture"  between the Authority and Citibank,  N.A., as
          trustee, pursuant to which the Bonds are outstanding and are secured;

     (b)  A copy of the Official  Statement of the Authority,  dated October 19,
          2005, relating to the Bonds,  excluding each of Appendix A, Appendix D
          and Appendix E thereto (the "Official Statement");





     (c)  A copy of the Bond Purchase Agreement;

     (d)  A copy of the Participation  Agreement  relating to the Bonds dated as
          of  November  1, 2005,  between the  Authority  and the  Company  (the
          "Participation Agreement");

     (e)  A copy  of the Tax  Regulatory  Agreement,  dated  November  1,  2005,
          between  the   Authority   and  the  Company   (the  "Tax   Regulatory
          Agreement");

     (f)  A copy of the municipal bond new issue insurance  policy issued by the
          Insurer;

and such  documents,  proceedings  and  matters of law which we have  considered
necessary  to enable us to render  this  opinion.  We have  assumed but have not
independently  verified that the  signatures  on all documents and  certificates
that we have examined were genuine.  We have further assumed for the purposes of
the opinions  expressed  below that the Bond  Purchase  Agreement  has been duly
authorized,  executed  and  delivered  by each  party  thereto,  other  than the
Authority.

     In  accordance  with our  understanding  with the Authority and as its Bond
Counsel,  we rendered legal advice and assistance to the Authority in connection
with the  preparation  of the  Official  Statement.  Rendering  such  advice and
assistance  involved,  among other things,  discussions and inquiries concerning
various  legal and  related  subjects,  and  reviews  of and  reports on certain
documents  and   proceedings.   We  also   participated   in  conferences   with
representatives   of  the   Authority,   the   Company   and  its   counsel  and
representatives of the Underwriters and their counsel, during which the contents
of the Official Statement and related matters were discussed and reviewed. Based
upon such advice,  assistance and participation,  we are of the opinion that the
summaries  contained in the Official  Statement  relating to the Bonds under the
captions  entitled  "THE  AUTHORITY,"  "SECURITY  AND SOURCES OF PAYMENT,"  "THE
AUCTION RATE BONDS"  (including all sections  referenced  therein,  but with the
exception  of  the   information   therein  under  the  subheading   "Securities
Depository"  and under the subheading  "Special  Considerations  Relating to the
Auction  Rate  Bonds  Bearing  Interest  at  Auction  Period  Rates--The  SEC is
Reviewing Broker-Dealer  Practices in the Market for Auction-Rate  Securities"),
"ALTERNATIVE INTEREST RATE MODES; MANDATORY TENDER FOR PURCHASE,"  "REDEMPTION,"
"THE PARTICIPATION  AGREEMENT," "THE TAX REGULATORY  AGREEMENT," "THE INDENTURE"
and "TAX MATTERS"  accurately  and fairly  present in all material  respects the
information  purported to be set forth in such summaries and nothing has come to
our attention  which causes us to believe that such  information in the Official
Statement  at the time  the  Authority  authorized  its use and  executed  it on
October 19, 2005,  did, and as it may have been amended or  supplemented,  does,
contain any untrue  statement  of a material  fact or omit to state any material
fact necessary to make the statements  made in such  summaries,  in light of the
circumstances under which they were made, not misleading.

     We are further of the opinion that:

     (1)  The  Authority has the right and power under the New York State Energy
          Research and  Development  Authority  Act (Title 9 of Article 8 of the
          Public  Authorities  Law of New York,  as  amended)  to enter into and


                                       2



          perform its  obligations  under the Bond Purchase  Agreement,  and the
          Bond  Purchase  Agreement  has been  duly  authorized,  executed,  and
          delivered  by the  Authority  and  constitutes  a  valid  and  binding
          obligation on the part of the Authority in accordance  with its terms,
          except  as the  enforcement  thereof  may  be  limited  by  applicable
          bankruptcy,  insolvency,  moratorium,  reorganization or other laws or
          judicial  decisions or principles  of equity  relating to or affecting
          the  enforcement  of  creditors'  rights  or  contractual  obligations
          generally.

     (2)  The Bonds are  exempted  securities  within  the  meaning  of  Section
          3(a)(2)  of the  Securities  Act of  1933,  as  amended,  and  Section
          304(a)(4) of the Trust Indenture Act of 1939, as amended.

     (3)  It is not  necessary in  connection  with the offering and sale of the
          Bonds to the public to register any security  under the Securities Act
          of 1933,  as  amended,  or to qualify  the  Indenture  under the Trust
          Indenture Act of 1939, as amended.

     We hereby  confirm  our  consent to the  references  to us in the  Official
Statement under the heading "LEGAL OPINIONS."



                                                     Very truly yours,

Ladies and Gentlemen:

     I am General Counsel to The Brooklyn Union Gas Company d/b/a KeySpan Energy
Delivery New York (the  "Company")  and as such have the general  supervision of
the Company's legal affairs and the personnel of the Company's Law Department. I
and other members of the Company's Law Department  have  represented the Company
in connection with the issue and sale of $55,000,000  aggregate principal amount
of Gas  Facilities  Revenue Bonds (The Brooklyn  Union Gas Company d/b/a KeySpan
Energy  Delivery New York  Project),  2005 Series B (the  "Bonds"),  of New York
State Energy  Research  and  Development  Authority  (the  "Authority")  and the
concurrent issue and delivery by the Company of its related promissory note (the
"Note")  pursuant to the  Participation  Agreement dated as of November 1, 2005,
herein  called the  "Participation  Agreement,"  between the  Authority  and the
Company,  and the  execution  and  delivery by the Company of the Bond  Purchase
Agreement dated October 26, 2005 (the "Bond Purchase  Agreement") among you, the
Authority  and  the  Company.  The  terms  "Official  Statement,"   "Indenture,"
"Insurance Policy," "Remarketing  Agreement,"  "Insurance Agreement," "Company's
Disclosure  Certificate,"  "Auction Agreement,"  "Broker-Dealer  Agreements" and
"Tax Regulatory Agreement" are used in this opinion with the respective meanings
assigned to such terms in the Bond Purchase Agreement.

     We have examined the Participation  Agreement, the Note, the Indenture, the
Tax Regulatory Agreement,  the Bond Purchase Agreement,  the Official Statement,
the  Insurance  Policy,  the  Insurance  Agreement,   the  Company's  Disclosure
Certificate,   the  Auction  Agreement,   the  Broker-Dealer   Agreements,   the
Remarketing Agreement and such other documents, and have discussed the foregoing
documents  and such other  matters,  with such  personnel of the  Company's  Law





Department  and such  officials  of the  Company,  as I consider  necessary  and
appropriate to enable me to express the opinions stated in this letter.

     I have  assumed,  with  your  consent,  for the  purposes  of the  opinions
expressed in this letter that the Participation  Agreement,  the Indenture,  the
Tax Regulatory  Agreement,  the Insurance Policy, the Insurance  Agreement,  the
Auction Agreement, the Broker-Dealer  Agreements,  the Remarketing Agreement and
the Bond Purchase Agreement have been duly authorized, executed and delivered by
each party thereto, other than the Company.

     Based upon the foregoing, it is my opinion that:

          (a) the Company  has been duly  incorporated  and is in good  standing
     under the laws of the State of New York, has corporate  power and authority
     to own its properties and to conduct its business and,  except as described
     in the  Official  Statement,  to the best of my  knowledge,  possesses  all
     material licenses and approvals necessary for the conduct of its business;

          (b) the  Company  has  corporate  power and  authority  to execute and
     deliver,  and to take all actions  required or permitted to be taken by the
     Company  by or  under,  and  to  perform  and  observe  the  covenants  and
     agreements  on its part  contained  in the  Bond  Purchase  Agreement,  the
     Participation  Agreement,  the  Note,  the Tax  Regulatory  Agreement,  the
     Insurance Agreement, the Auction Agreement,  the Broker-Dealer  Agreements,
     the Company's Disclosure Certificate, and the Remarketing Agreement;

          (c) the Company has duly taken all  corporate  action  necessary to be
     taken by it prior to the date  hereof  for the  authorization  of:  (i) the
     execution,  delivery and  performance  by the Company of the Bond  Purchase
     Agreement,  the  Participation  Agreement,  the  Note,  the Tax  Regulatory
     Agreement,   the   Insurance   Agreement,   the  Auction   Agreement,   the
     Broker-Dealer  Agreements,  the Company's Disclosure  Certificate,  and the
     Remarketing Agreement,  (ii) the distribution of the Official Statement and
     (iii) the carrying out, giving effect to,  consummation  and performance by
     the Company of the  transactions  and obligations  contemplated by the Bond
     Purchase Agreement,  the Participation  Agreement,  the Note, the Insurance
     Policy, the Insurance Agreement,  the Auction Agreement,  the Broker-Dealer
     Agreements,  the  Company's  Disclosure  Certificate,  the  Tax  Regulatory

     Agreement,   the  Broker-Dealer   Agreements,   the  Company's   Disclosure
     Certificate,  and the  Remarketing  Agreement  have been duly  executed and
     delivered by the Company and  constitute  valid and binding  obligations of
     the  Company,  enforceable  against  the Company in  accordance  with their
     respective  terms,  except as the  enforcement  thereof  may be  limited by
     bankruptcy, insolvency,  reorganization,  moratorium or other laws relating
     to or  affecting  the  enforcement  of  creditors'  rights  or  contractual


                                       2



     obligations  generally or by  principles of equity  (regardless  of whether
     such  principles  are  considered  in a proceeding at law or in equity) and
     except as rights of  indemnification  under the Bond Purchase  Agreement or
     the Remarketing Agreement may be limited by principles of public policy;

          (e) the  execution  and  delivery by the Company of the Bond  Purchase
     Agreement,  the  Participation  Agreement,  the  Note,  the Tax  Regulatory
     Agreement,   the   Insurance   Agreement,   the  Auction   Agreement,   the
     Broker-Dealer  Agreements,  the Company's Disclosure  Certificate,  and the
     Remarketing  Agreement,  the  compliance  by the  Company  with the  terms,
     conditions or provisions  thereof,  and the  consummation by the Company of
     the  transactions  therein  contemplated  do not and will not  violate  any
     existing  New  York  or  federal  law  or  regulation,  or  contravene  the
     Certificate of Incorporation or by-laws of the Company,  or, to the best of
     my knowledge,  any rule,  order,  writ,  injunction or decree of any court,
     federal  or  state   regulatory  body,   administrative   agency  or  other
     governmental  body applicable to the Company,  or result in a breach of any
     of the terms,  conditions or  provisions  of, or constitute a default under
     any mortgage, indenture,  agreement or instrument to which the Company is a
     party or by which it or any of its  properties is bound and of which I have
     knowledge,  or,  to the best of my  knowledge,  result in the  creation  or
     imposition  of any  mortgage,  lien,  charge or  encumbrance  of any nature
     whatsoever upon any of the properties or assets of the Company;

          (f) on and as of the date  hereof,  all  authorizations,  consents and

     instrumentality or court required to be obtained,  given or taken on behalf
     of the Company in connection with the  procurement of the Insurance  Policy
     and the  execution and delivery of, and  performance  by the Company of its
     obligations   under,  the  Bond  Purchase   Agreement,   the  Participation
     Agreement, the Note, the Tax Regulatory Agreement, the Insurance Agreement,
     the  Auction  Agreement,  the  Broker-Dealer   Agreements,   the  Company's

     except as may be set forth in the Official  Statement,  is any such action,
     suit, proceeding, inquiry or investigation pending or threatened against or
     affecting the Company,  wherein an unfavorable decision,  ruling or finding

          (h) the  Company  is not in  default  under  any  indenture  or  other
     agreement or instrument  governing  outstanding  indebtedness issued by the
     Company  nor, to the best of my  knowledge,  has any event  occurred and is
     continuing  which  with  notice  or the  passage  of  time  or  both  would
     constitute a default under any such document;

     headings  "Introductory  Statement,"  "Use  of  Proceeds,"  "The  Project,"
     "Security  and Sources of Payment,"  "The  Auction Rate Bonds"  (other than

          (j) the Bonds are  exempted  securities  under the  Securities  Act of

     Indenture under the Trust Indenture Act of 1939, as amended.

     In  expressing  the opinion in paragraph  (j) of this letter I have relied,
with your  approval,  upon the opinion of even date  herewith,  addressed to the
Company,  of Hawkins  Delafield & Wood LLP with respect to the  treatment of the
Bonds under the Internal Revenue Code of 1954.

     Additionally,  I advise you that,  without  having  undertaken to determine
independently  the accuracy or completeness  of the statements  contained in the
Official Statement,  except as set forth above, nothing has come to my attention
in the course of my participation  in the preparation of the Official  Statement
and in the transactions contemplated thereby, or in the performance of my duties
as General  Counsel to the Company or  otherwise,  that would lead me to believe
that, as of its date or as of the date hereof, the Official Statement, contained
or contains any untrue or misleading  statement of a material fact or omitted or
omits to state any material fact  necessary to make the statements  therein,  in
the light of the circumstances under which they were made, not misleading.

Ladies and Gentlemen:

     I am General  Counsel of New York State  Energy  Research  and  Development
Authority  (the  "Authority")  and  have  acted as such in  connection  with the
issuance of $55,000,000  aggregate  principal  amount of Gas Facilities  Revenue
Bonds (The Brooklyn  Union Gas Company d/b/a  KeySpan  Energy  Delivery New York
Project),  2005  Series  B (the  "Bonds")  by you  pursuant  to a Bond  Purchase
Agreement  dated October 26, 2005,  among the Authority,  The Brooklyn Union Gas
Company d/b/a KeySpan  Energy  Delivery New York (the  "Company"),  and you (the
"Bond Purchase  Agreement").  I have examined, or supervised the examination of,
(i) the Bond  Resolution No. 1094 adopted by the Authority on September 19, 2005
relating to the Bonds (the "Resolution"),  (ii) the Indenture of Trust, dated as
of November 1, 2005, between Citibank,  N.A., as trustee (the "Trustee") and the
Authority,  relating  to the Bonds (the  "Indenture"),  (iii) the  Participation
Agreement,  dated as  November 1, 2005,  between the Company and the  Authority,
relating to the Bonds (the  "Participation  Agreement"),  (iv) the Bond Purchase
Agreement,  relating to the Bonds, (v) the Bond Purchase Trust Agreement,  dated
as of November 1, 2005,  between the Authority and Citibank,  N.A., as Registrar
and Paying Agent,  relating to the Bonds (the "Bond Purchase Trust  Agreement"),
(vi) the Tax  Regulatory  Agreement,  dated as of the date  hereof,  between the
Authority  and  the  Company,   relating  to  the  Bonds  (the  "Tax  Regulatory
Agreement"),  (vii) the Official  Statement dated October 19, 2005,  relating to
the Bonds (the  "Official  Statement"),  excluding the Appendices  thereto,  and
(viii) such further documents,  and have made such further  investigation,  as I
have deemed necessary to render the opinions set forth below.

     I have  assumed,  with  your  consent,  for the  purposes  of the  opinions
expressed in this letter that the Participation  Agreement,  the Indenture,  the





Tax Regulatory Agreement,  the Bonds, the Bond Purchase Trust Agreement, and the
Bond Purchase  Agreement have been duly authorized,  executed,  and delivered by
each party thereto, other than the Authority.

         Based on the foregoing, it is my opinion that:

     1. The  Authority is a body  corporate and politic,  constituting  a public
benefit  corporation  under the laws of the State of New York.  The Authority is
empowered  by  the  provisions  of  the  New  York  State  Energy  Research  and
Development Authority Act, Title 9 of Article 8 of the Public Authorities Law of
the State of New York (the "Act"),  to issue the Bonds,  to cause the Company to
deliver the Company Obligation (as defined in the Indenture) to the Trustee,  to
assign and pledge to the Trustee  certain of the  Authority's  rights  under the
Participation  Agreement,  as  security  for  payment  of the  principal  of and
premium,  if any, and  interest on the Bonds,  and to enter into and perform its
obligations under the Bond Purchase Agreement,  the Indenture, the Participation
Agreement,  the Bond Purchase Trust Agreement, the Tax Regulatory Agreement, and
any other  instrument  or agreement to which the  Authority is a party and which
has been  executed  in  connection  with the  transactions  contemplated  by the
documents  identified in the introductory  paragraph of this opinion in order to
accomplish the foregoing actions.

     2. The  Authority  has full power and  authority to execute and deliver the
Bond  Purchase  Agreement,  the  Tax  Regulatory  Agreement,  the  Participation
Agreement, the Bond Purchase Trust Agreement, and the Indenture, and to take all
actions  required or permitted to be taken by the Authority by or under,  and to
perform and observe the covenants and  agreements on its part  contained in, the
Bond Purchase Agreement,  the Indenture,  the Participation  Agreement, the Bond
Purchase Trust Agreement, the Tax Regulatory Agreement, and any other instrument
or  agreement  relating  thereto  to which  the  Authority  is a party,  and the
Authority has complied with all provisions of applicable law, including the Act,
in all matters related to such actions.

     3. The Authority has duly authorized and has taken all action  necessary to
be taken by it or on its behalf for: (i) the offering and sale of the Bonds upon
the terms and  conditions  and for the purposes  set forth in the Bond  Purchase
Agreement  and in the Official  Statement;  (ii) the  execution,  delivery,  and
performance of the Bond Purchase  Agreement,  the Indenture,  the  Participation
Agreement,  the Tax Regulatory Agreement, the Bond Purchase Trust Agreement, and
any and all  such  other  agreements  and  documents  as may be  required  to be
executed,  delivered,  and  performed by the Authority to carry out, give effect
to, and consummate the transactions provided for in the Bond Purchase Agreement,
the Indenture,  the Tax Regulatory Agreement,  the Participation  Agreement, the
Bond Purchase Trust Agreement,  and the Official Statement;  (iii) the approval,
execution,  delivery,  and distribution of the Official Statement;  and (iv) the
carrying  out,   giving  effect  to,   consummation,   and  performance  of  the
transactions and obligations  contemplated by the Bond Purchase Agreement and by
the Official  Statement;  provided that no opinion is expressed  with respect to
compliance  with the  securities or "Blue Sky" laws of the various states of the
United States.

     4. The  Indenture  constitutes  a pledge and  assignment  to the Trustee of
substantially all of the Authority's rights and interest under the Participation
Agreement, the Company Obligation, and the Tax Regulatory Agreement, all for the
benefit of the holders from time to time of the Bonds.  I have caused  financing


                                       2



statements with respect to such pledge and assignment to be filed in proper form
pursuant to the New York State  Uniform  Commercial  Code,  in the office of the
Secretary of State of the State of New York.

     5. The Bonds have been duly authorized,  executed,  issued,  and delivered,
and  constitute   valid  and  binding  limited   obligations  of  the  Authority
enforceable  in  accordance  with their terms and the terms of the Indenture and
entitled to the  benefits  and  security of such  Indenture,  the  Participation
Agreement,  the Bond Purchase Trust Agreement,  the Company Obligation,  and the
Act,  except to the extent  enforcement  thereof  may be limited by  bankruptcy,
insolvency,  moratorium,  reorganization,  or similar laws affecting  creditors'
rights.  The  Indenture,   the  Participation   Agreement,  the  Tax  Regulatory
Agreement,  the Bond Purchase Trust Agreement,  and the Bond Purchase  Agreement
have  been  duly  authorized,  executed,  and  delivered  by the  Authority  and
constitute legal, valid, and binding  obligations of the Authority,  enforceable
in accordance with their terms except to the extent  enforcement  thereof may be
limited by bankruptcy, insolvency, moratorium,  reorganization, or other similar
laws affecting creditors' rights.

     6.  The  execution   and  delivery  of  the  Official   Statement  and  the
authorization,  execution,  delivery,  and  performance  of  the  Bond  Purchase
Agreement,  the  Indenture,  the  Participation  Agreement,  the Tax  Regulatory
Agreement,  the Bond Purchase Trust Agreement, and the other agreements provided
for in the Bond Purchase Agreement and compliance with the provisions thereof do
not and will not  conflict  with or  constitute  on the part of the  Authority a
breach  of or a default  under any  existing  constitutional  provision  or law,
court,  or  administrative  regulation,  rule,  decree  or  order,  or any rule,
regulation,  or by-law of the  Authority,  or so far as I am aware after  having
made a reasonable investigation,  any agreement,  indenture, mortgage, lease, or
other  instrument  to which the  Authority  or any of its officers in his or her
respective  capacity as such is subject or by which the  Authority or any of its
properties or any such officer is bound.

     7. The approval or waiver of approval has been  obtained  from the Governor
of the State of New York,  and approval has been obtained from the  Commissioner
of Taxation and Finance,  the State  Comptroller,  and the New York State Public
Authorities  Control Board.  No other  authorization,  consent,  or approval of,
notice to, registration or filing with, or action in respect of any governmental
body,  agency,  or other  instrumentality  or court is required to be  obtained,
given,  or taken on behalf of the  Authority in connection  with the  execution,
delivery,  and performance by the Authority of the Bond Purchase Agreement,  the
Indenture,  the Participation  Agreement, the Tax Regulatory Agreement, the Bond
Purchase Trust  Agreement,  the Official  Statement,  and any other agreement or
instrument  to which the  Authority  is a party and which has been  executed  in
connection  with the  consummation  of the  transactions  contemplated  thereby;
provided  that no opinion is  expressed  with  respect  to  compliance  with the
securities or "Blue Sky" laws of the various states of the United States.

     8. The  statements  made in the Official  Statement  under the heading "THE
AUTHORITY",  insofar as such  statements  purport  to  describe  the  Authority,
present a fair and accurate description thereof.

     There is no action, suit,  proceeding,  inquiry, or investigation at law or
in equity, or before or by any court, public board or body, pending,  or, to the
best of my knowledge,  threatened against or affecting the Authority, wherein an
unfavorable decision, ruling, or finding would adversely affect the transactions


                                       3



on the part of the Authority  provided for by the Bond Purchase  Agreement,  the
Bonds,  the  Participation  Agreement,  the Tax Regulatory  Agreement,  the Bond
Purchase Trust Agreement,  or the Indenture or the validity or enforceability of
the Bonds,  the  Indenture,  the  Participation  Agreement,  the Tax  Regulatory
Agreement,  the Bond Purchase Trust  Agreement or any agreement or instrument to
which the Authority is a party and which is used or contemplated  for use in the
consummation of the transaction provided for in the Bond Purchase Agreement.

                                   Sincerely,


                                   Roger D. Avent

Ladies and Gentlemen:

I am Counsel of Financial Guaranty Insurance Company ("Financial Guaranty"), and
have been  requested to render an opinion  concerning  the issuance by Financial
Guaranty of its  Municipal  Bond New Issue  Insurance  Policy (the  "Policy") in
connection  with the issuance of the Bonds.  I have examined such  documents and
records as I have deemed  relevant for purposes of this  opinion,  including (a)
the Certificate of Incorporation of Financial Guaranty, including all amendments
thereto,  (b) the amended By-laws of Financial Guaranty as in effect on the date
hereof,  (c) the  certificate of authority  issued to Financial  Guaranty by the
Superintendent  of Insurance of the State of New York,  (d) the  certificate  of
authority issued to Financial  Guaranty by the  Superintendent of Finance of the
State of New York, (e) the executed  Policy,  (f) the statements in the Official
Statement   dated  October  19,  2005  relating  to  the  Bonds  (the  "Official
Statement")  under the caption  "THE  INSURANCE  POLICY"  and  Appendix D to the





FGIC

Page 2

Official  Statement and (g) the Insurance  Agreement dated November 1, 2005 (the
"Insurance  Agreement")  between  Financial  Guaranty and The Brooklyn Union Gas
Company d/b/a KeySpan Energy Delivery New York (the "Company").

On the basis of the foregoing, it is my opinion that:

     (1) Financial  Guaranty is a stock insurance  corporation  validly existing
and in good standing under the laws of the State of New York and qualified to do
business therein and is licensed and authorized to issue its financial  guaranty
insurance  policies,  including  the Policy,  under the laws of the State of New
York.

     (2) The  Policy  has been  duly  executed  and is valid  and  binding  upon
Financial  Guaranty and  enforceable  in accordance  with its terms,  subject to
applicable laws affecting creditors' rights generally.

     (3) The execution and delivery by Financial Guaranty of the Policy, and the
performance by Financial  Guaranty of the terms thereof,  will not: (i) conflict
with any of the  terms,  conditions  or  provisions  of (A) the  Certificate  of
Incorporation of Financial Guaranty,  including any amendments thereto,  (B) the
amended By-laws of Financial Guaranty as in effect on the date hereof, or (C) to
my actual  knowledge,  any  covenant  contained  in any  contract,  agreement or
instrument to which Financial  Guaranty is bound,  which contract,  agreement or
instrument is material to the financial condition of Financial Guaranty; (ii) to
my actual knowledge,  constitute a default under any such contract, agreement or
instrument  or (iii)  contravene  any law or  governmental  regulation  or order
presently binding on Financial  Guaranty the contravention of which would affect
the validity and enforcement of the Policy.

     (4)  The  Insurance  Agreement  has  been  duly  authorized,  executed  and
delivered by Financial Guaranty and, assuming the due  authorization,  execution
and delivery  thereof by the Company,  constitutes  a valid and legally  binding
instrument of Financial  Guaranty,  enforceable  against  Financial  Guaranty in
accordance  with its  terms,  except as such  enforceability  may be  limited by
bankruptcy, insolvency, reorganization, liquidation, moratorium or other similar
laws affecting the enforcement of creditors' rights generally as such laws would
apply in the event of the  liquidation,  conservation or  rehabilitation  of, or
other similar occurrence with respect to, Financial Guaranty.

     (5) Financial Guaranty, as an insurance company, is not eligible for relief
under  the  Federal  Bankruptcy  Laws.  Any  proceedings  for  the  liquidation,
conservation or  rehabilitation  of Financial  Guaranty would be governed by the
provisions of the Insurance Law of the State of New York.

     (6) The statements  described above in the Official  Statement  relating to
Financial  Guaranty and the Policy  accurately and fairly  represent the summary
information  set forth therein and do not omit any material fact with respect to





FGIC
November 1, 2005
Page 3

the  description  of Financial  Guaranty  relative to the material  terms of the
Policy or the ability of Financial  Guaranty to meet its  obligations  under the
Policy.  The form of Policy contained in Appendix D to the Official Statement is
a true and complete copy of the form of the Policy.

     (7) The Policy  constitutes  an  "insurance  policy"  within the meaning of
Section 3(a)(8) of the Securities Act of 1933, as amended (the "Act") and is not
required to be registered under the Act.

Very truly yours,



Carmen Tigreros
