                                             January 12, 1994

  Dear Stockholder:

          A Special Meeting of Stockholders (the "PSGS Special Meeting") of
  Pennsylvania & Southern Gas Company ("PSGS") will be held on February 10, 1994
  at 9:30 a.m., local time, at the Doubletree Hotel, Broad Street at Locust,
  Philadelphia, Pennsylvania.

          At the PSGS Special Meeting, you will be asked to consider and vote
  upon the Agreement and Plan of Merger, dated July 27, 1993 (the "Merger
  Agreement"), between PSGS and NUI Corporation ("NUI") providing for the merger
  of PSGS with and into NUI (the "PSGS Merger").

          NUI is a natural gas distribution company headquartered in Bedminster,
  New Jersey. The attached Proxy Statement/Prospectus includes pro forma
  financial information showing the effects on NUI of the PSGS Merger.

          If the PSGS Merger is approved and consummated, each share of PSGS
  Common Stock issued and outstanding (other than shares owned by NUI, PSGS or
  any of their respective subsidiaries (which will be canceled) and shares held
  by PSGS Stockholders who perfect appraisal rights under Delaware law) will be
  converted, at the time the PSGS Merger becomes effective (the "Effective Time
  of the PSGS Merger"), into the right to receive the number of shares of NUI
  common stock, no par value ("NUI Common Stock"), or fraction thereof rounded
  to the nearest thousandth of a share of NUI Common Stock, equal to the number
  determined by dividing $71.50 by the arithmetic average of the daily closing
  price per share of NUI Common Stock (the "Average Market Price") as reported
  on the Composite Tape of the New York Stock Exchange (the "NYSE") for the
  period of twenty days ending on the trading day immediately prior to the
  Effective Time of the PSGS Merger; provided, however, that the number of
  shares of NUI Common Stock that will be issued upon the conversion of each
  share of PSGS Common Stock shall in no event exceed 3.0 shares or be fewer
  than 2.4 shares of NUI Common Stock. On January 7, 1994, the last sale price
  for NUI Common Stock, as reported on the NYSE Composite Tape, was $26.00 per
  share. If the Average Market Price of NUI Common Stock, determined in
  accordance with the Merger Agreement, were $28.375, each PSGS Stockholder
  would receive in the PSGS Merger 2.520 shares of NUI Common Stock for each
  share of PSGS Common Stock held by such stockholder.

          The attached Proxy Statement/Prospectus contains important information
  concerning the PSGS Merger. We urge you to give it your careful attention.

          The Board of Directors of PSGS has carefully considered the Merger
  Agreement and believes that the PSGS Merger is fair to and in the best
  interests of PSGS and its stockholders. ACCORDINGLY, YOUR BOARD OF DIRECTORS
  UNANIMOUSLY RECOMMENDS THAT YOU VOTE FOR APPROVAL OF THE MERGER AGREEMENT.

          Your participation in the PSGS Special Meeting, in person or by proxy,
  is important. Please mark, sign, date and return as soon as possible the
  enclosed proxy card in the accompanying postage paid return envelope, whether
  or not you plan to attend the PSGS Special Meeting. Returning the proxy card
  does not prejudice your right to vote your shares in person at the PSGS
  Special Meeting if you choose to do so.

                                             Sincerely yours,

               Proxy Statement/Prospectus, providing for the merger of PSGS with
               and into NUI (the "PSGS Merger"), pursuant to which each share of
               PSGS common stock, $1.25 par value per share ("the PSGS Common
               Stock") outstanding will be converted into the right to receive
               that number of shares of NUI common stock, no par value ("NUI
               Common Stock"), having a value, as determined in accordance with
               the Merger Agreement, of $71.50 per share; provided, however,
               that the number of shares of NUI Common Stock to be exchanged for
               each share of PSGS Common Stock in the Merger shall be not less
               than 2.4 or more than 3.0. 

          2.   Such other matters as may properly be brought before the PSGS

                                  NUI Corporation
                        Pennsylvania & Southern Gas Company

                      Shares of NUI Corporation Common Stock

  Special Meeting of PSGS Stockholders to be Held February 10, 1994.

          NUI Corporation, a New Jersey corporation ("NUI"), has filed a
  Registration Statement on Form S-4 (the "Registration Statement") with the
  Securities and Exchange Commission (the "SEC") pursuant to the Securities Act
  of 1933 (the "Securities Act") covering shares of NUI common stock, no par
  value (the "NUI Common Stock"), issuable in connection with the merger of
  Pennsylvania & Southern Gas Company, a Delaware corporation ("PSGS"), with and
  into NUI (the "PSGS Merger"), pursuant to the Agreement and Plan of Merger,
  dated July 27, 1993, by and between NUI and PSGS (the "Merger Agreement") upon
  the conversion of shares of PSGS common stock, par value of $1.25 per share
  (the "PSGS Common Stock"). At the time the PSGS Merger becomes effective (the
  "Effective Time of the PSGS Merger"), each share of PSGS Common Stock issued
  and outstanding (other than shares owned by NUI, PSGS or any of their
  respective subsidiaries which will be cancelled ("PSGS Cancelled Shares") and
  shares held by holders of shares of PSGS Common Stock ("PSGS Stockholders")
  who perfect appraisal rights under Delaware law ("PSGS Dissenting Shares"))
  will be converted into the right to receive the number of shares of NUI Common
  Stock, or fraction thereof rounded to the nearest thousandth of a share of NUI
  Common Stock, equal to the number determined by dividing $71.50 by the
  arithmetic average of the daily closing price per share of NUI Common Stock
  (the "Average Market Price") as reported on the Composite Tape of the New York
  Stock Exchange (the "NYSE"), for the period of twenty trading days ending on
  the trading day immediately prior to the Effective Time of the PSGS Merger;
  provided, however, that the number of shares of NUI Common Stock that will be
  issued upon the conversion of each share of PSGS Common Stock shall in no
  event exceed 3.0 shares or be fewer than 2.4 shares of NUI Common Stock (the
  "Merger Consideration"). On January 7, 1994, the last sale price for NUI
  Common Stock, as reported on the NYSE Composite Tape, was $26.00 per share. If
  the Average Market Price of NUI Common Stock, determined in accordance with
  the Merger Agreement, were $28.375, each PSGS Stockholder would receive in the
  PSGS Merger 2.520 shares of NUI Common Stock for each share of PSGS Common
  Stock held by such stockholder.

          This Proxy Statement/Prospectus also constitutes the prospectus of NUI
  filed as part of such Registration Statement. See "Available Information."

          In connection with the transactions described in this Proxy
  Statement/Prospectus, PSGS Stockholders, who otherwise comply with the
  applicable provisions of the Delaware General Corporation Law ("DGCL"), may
  seek payment of the fair value of their shares of PSGS Common Stock. See
  "Appraisal Rights" in this Proxy Statement/Prospectus and Annex C hereto, for
  a description of the procedures to be followed in order to perfect such
  appraisal rights.


              THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED 
                 BY THE SECURITIES AND EXCHANGE COMMISSION OR ANY
                 STATE REGULATORY AUTHORITY NOR HAS THE COMMISSION
                   OR ANY STATE REGULATORY AUTHORITY PASSED UPON
                   THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS.
                      ANY REPRESENTATION TO THE CONTRARY IS A
                                 CRIMINAL OFFENSE.

                                      SUMMARY

          The following is a summary of certain information contained in this
  Proxy Statement/Prospectus. This summary is not intended to be complete and is
  qualified in its entirety by the more detailed information and financial
  statements contained elsewhere or incorporated by reference in this Proxy
  Statement/Prospectus and the attached Annexes, all of which are important and
  should be reviewed carefully. Capitalized terms used herein without definition
  shall have the meaning ascribed to them elsewhere in this Proxy
  Statement/Prospectus.

  The Parties

          NUI. NUI, through its principal subsidiary, Elizabethtown Gas Company
  ("EGC"), is engaged in the distribution of natural gas to approximately
  320,000 customers in two states. The New Jersey Division, which serves Union
  and Middlesex Counties in central New Jersey and portions of northwestern New
  Jersey, does business as Elizabethtown Gas Company and the Florida Division,
  which serves Dade and Broward Counties in southern Florida and Brevard and St.
  Lucie Counties in eastern Florida, does business as City Gas Company of
  Florida.

          PSGS. PSGS is engaged in the sale and distribution of natural gas to
  residential, commercial and industrial customers within prescribed areas of
  Maryland, New York, North Carolina and Pennsylvania.

  PSGS Stockholder Meeting

          The Special Meeting of the PSGS Stockholders (the "PSGS Special
  Meeting") will be held on February 10, 1994 at 9:30 a.m., local time, at the
  Doubletree Hotel, Broad Street at Locust, Philadelphia, Pennsylvania. Only
  holders of record of PSGS Common Stock at the close of business on January 11,
  1994 (the "PSGS Record Date"), will be entitled to notice of and to vote at,
  the PSGS Special Meeting. At such date there were 235,857 shares of PSGS
  Common Stock outstanding and entitled to vote. The purposes of the PSGS
  Special Meeting are (a) to consider and act upon a proposal to approve and
  adopt the Merger Agreement and (b) to transact such other business as may
  properly be brought before the PSGS Special Meeting or any adjournments
  thereof.

  Voting

          The affirmative vote of a majority of the outstanding shares of PSGS
  Common Stock is required to approve the adoption of the Merger Agreement. The
  executive officers and directors of PSGS, in the aggregate, beneficially own
  32% of the PSGS Common Stock outstanding as of the PSGS Record Date. Such
  persons have informed PSGS that all such shares over which they hold voting
  power will be voted for approval of the Merger Agreement. A majority of the
  issued and outstanding shares of PSGS Common Stock, represented in person or
  by proxy, shall constitute a quorum at the PSGS Special Meeting.

  The Proposed Mergers

          General. NUI and PSGS contemplate that the merger of EGC with and into
  NUI (the "EGC Merger" and, collectively with the PSGS Merger, the "Mergers")
  will take place immediately after the PSGS Merger. The result of these
  transactions will be a single surviving company, NUI, conducting its business,

                                         8
<PAGE>



  the business of EGC and the business of PSGS.

          Following the effectiveness of the Mergers, NUI will succeed by
  operation of law to the assets, liabilities and operations of each of PSGS and
  EGC. As a result of the Mergers, the separate corporate existences of PSGS and
  EGC will cease, and NUI will continue the combined operations of PSGS and EGC.
  See "PSGS Merger-Basic Terms of Merger Agreement-Operation of PSGS After the
  PSGS Merger."

          Conversion of PSGS Common Stock. At the Effective Time of the PSGS
  Merger, each share of PSGS Common Stock issued and outstanding (other than
  PSGS Cancelled Shares and PSGS Dissenting Shares) will be converted into the
  right to receive the number of shares of NUI Common Stock, or fraction thereof
  rounded to the nearest thousandth of a share of NUI Common Stock, equal to the
  number determined by dividing $71.50 by the arithmetic average of the daily
  closing price per share of NUI Common Stock as reported on the Composite Tape
  of the NYSE for the period of twenty trading days ending on the trading day
  immediately prior to the Effective Time of the PSGS Merger; provided, however,
  that the number of shares of NUI Common Stock that will be issued upon the
  conversion of each share of PSGS Common Stock shall in no event exceed 3.0
  shares or be fewer than 2.4 shares of NUI Common Stock. Market fluctuations in
  the price of NUI Common Stock will affect the conversion ratio applicable to
  the PSGS Common Stock. For additional information concerning the treatment of
  PSGS Common Stock in the PSGS Merger, see "PSGS Merger-Basic Terms of Merger
  Agreement-Conversion of PSGS Common Stock."

          On June 23, 1993, the last trading day before the announcement of the
  preliminary agreement between NUI and PSGS with respect to the PSGS Merger,
  the closing price per share for NUI Common Stock on the NYSE was $26.375; on
  July 26, 1993, the last trading day before the announcement of the signing of
  the Merger Agreement, the closing price per share for NUI Common Stock on the
  NYSE was $29.00; and on January 7, 1994, the closing price per share for NUI
  Common Stock on the NYSE was $26.00.

          Appraisal Rights. Holders of PSGS Common Stock will be entitled to
  appraisal rights under Delaware law, if such rights are properly perfected,
  because such persons hold stock of a constituent corporation a merger which is
  neither listed on a national securities exchange nor held of record by more
  than 2,000 holders. See "Appraisal Rights" for a discussion of the procedures
  that must be followed by holders of PSGS Common Stock in order to perfect and
  exercise such appraisal rights.

          Reasons for the Mergers. The Board of Directors of PSGS believes that
  the PSGS Merger will result in a stronger and more effective company, better
  able to compete effectively going forward and to take advantage of
  opportunities that would not be available to PSGS on its own. The PSGS Board
  of Directors also believes that the PSGS Merger will result in a broader range
  of products and services being available to PSGS' customers, while providing
  PSGS Stockholders the opportunity to continue as equity participants with a
  more liquid investment in a larger company. For information on the matters
  considered by the Board of Directors of PSGS in approving and recommending the
  PSGS Merger, see "The Proposed Mergers-Background and Reasons for the Mergers"
  and "Recommendations of the PSGS Board of Directors."

          Recommendations of the PSGS Board of Directors. The Board of Directors
  of PSGS believes that the terms of the PSGS Merger are fair to and in the best
  interests of PSGS and the PSGS Stockholders, has approved the Merger Agreement
  and unanimously recommends that the PSGS Stockholders vote FOR approval of the

                                         9
<PAGE>



  proposal to adopt the Merger Agreement. In making this determination, the
  Board of Directors of PSGS has considered the factors described under "The
  Proposed Mergers-Background of and Reasons for the Mergers."

          Conditions to Consummation of the PSGS Merger; Regulatory Approvals.
  The obligation of each of NUI and PSGS to consummate the PSGS Merger is
  subject to the receipt of certain regulatory approvals, other consents and
  approval by the PSGS Stockholders. See "PSGS Merger-Basic Terms of Merger
  Agreement-Conditions to Consummation of the PSGS Merger" and "-Regulatory
  Filings and Approvals."

          Termination and Amendment of the Merger Agreement. The Merger
  Agreement may be terminated at any time prior to the Effective Time of the
  PSGS Merger, before or after approval by the PSGS Stockholders of matters
  presented to them in connection with the PSGS Merger: (a) by mutual consent of
  NUI and PSGS; (b) by either NUI or PSGS if: (i) a permanent injunction is
  entered, enforced or deemed applicable to the PSGS Merger which prohibits the
  consummation of the PSGS Merger and all appeals of such injunction shall have
  been taken and shall have been unsuccessful; (ii) the required approval of the
  PSGS Stockholders has not been obtained; (iii) any United States federal,
  state or local government (including the District of Columbia), governmental
  or regulatory authority, governmental or regulatory body, governmental or
  regulatory agency or court or other judicial authority ("Governmental
  Entity"), the consent of which is a condition to the obligations of NUI and
  PSGS to consummate the PSGS Merger pursuant to the Merger Agreement, shall
  have determined not to grant its consent and all appeals of such determination
  have been taken and have been unsuccessful or (iv) without the fault of the
  terminating party, the PSGS Merger has not been consummated by May 2, 1994 or
  (c) by NUI if: (i) a permanent injunction is entered, enforced or deemed
  applicable to the EGC Merger which prohibits the consummation of the EGC
  Merger and all appeals of such injunction shall have been taken and shall have
  been unsuccessful or (ii) any Governmental Entity, the consent of which is a
  condition to the obligations of NUI or EGC to consummate the EGC Merger, shall
  have determined not to grant its consent and all appeals of such determination
  have been taken and have been unsuccessful.

          The Merger Agreement may be amended by NUI and PSGS by mutual action
  taken by their respective Boards of Directors, except that, after the approval
  by the PSGS Stockholders, no amendment may be made that would change (a) the
  amount or type of consideration to be received for or on conversion of all or
  any of the shares of the PSGS Common Stock upon consummation of the PSGS
  Merger, (b) any term of the certificate of incorporation of NUI or (c) any of
  the terms or conditions of the Merger Agreement if such change would adversely
  affect the PSGS Stockholders. 

          See "PSGS Merger-Basic Terms of Merger Agreement-Amendment and
  Termination."

          Operations After the Mergers. Following the Mergers, EGC's New Jersey
  Division will be operated as a separate division of NUI under the name
  "Elizabethtown Gas Company," EGC's Florida Division will be operated as a
  separate division of NUI under the name "City Gas Company of Florida," PSGS
  will be operated as a separate division of NUI under the name "Pennsylvania &
  Southern Gas Company" and PSGS and EGC will cease their separate corporate
  existence. See "PSGS Merger-Basic Terms of Merger Agreement-Operation of PSGS
  After the PSGS Merger," and "EGC Merger."

          Opinion of PSGS Financial Advisor. Berwind Financial Group, Inc.

                                        10
<PAGE>



  ("Berwind") has delivered to the Board of Directors of PSGS its opinion that,
  as of January 10, 1994, the consideration to be received by PSGS Stockholders
  in the PSGS Merger is fair from a financial point of view to such
  stockholders. For information on the assumptions made, matters considered and
  limitations on the review by Berwind, see "The Proposed Mergers-Opinion of
  PSGS Financial Advisor." Stockholders are urged to read in its entirety the
  opinion of Berwind dated January 10, 1994 and attached as Annex B to this
  Proxy Statement/Prospectus.

          Certain Federal Income Tax Considerations. In the opinion of
  Montgomery, McCracken, Walker & Rhoads, counsel for PSGS, the PSGS Merger will
  qualify for federal income tax purposes as a reorganization within the meaning
  of Section 368 of the Internal Revenue Code of 1986, as amended; and,
  accordingly, no gain or loss will be recognized by the PSGS Stockholders upon
  their receipt of the NUI Common Stock in exchange for their PSGS Common Stock,
  except to the extent that cash is received in lieu of a fractional share of
  NUI Common Stock. For a more complete description of the federal income tax
  consequences of the PSGS Merger, see "PSGS Merger-Federal Income Tax
  Considerations." Because the tax consequences of the PSGS Merger under
  federal, state, local and foreign tax laws may vary, depending upon an
  individual taxpayer's particular situation, it is recommended that each PSGS
  Stockholder consult with his or her tax advisor regarding the applicable tax
  consequences of the PSGS Merger.

          Interests of PSGS Management and Directors. In considering the
  respective recommendations of the Board of Directors of PSGS with respect to
  approval of the Merger Agreement, PSGS Stockholders should be aware that
  certain members of PSGS' management and PSGS' Board of Directors have certain
  interests in the PSGS Merger that are in addition to the interests of PSGS
  Stockholders generally. NUI has agreed to enter into, at or prior to the
  Effective Time of the PSGS Merger, an employment agreement with Lyle C.
  Motley, Jr., President and Chief Executive officer of PSGS and a member of the
  PSGS Board of Directors. Such employment agreement provides for a term of
  three years with certain benefits upon early termination, demotion or
  relocation. In addition, NUI has agreed to enter into employment agreements
  with James W. Carl (Vice President of PSGS), James K. Turpin (Vice President
  of PSGS), Bernard L. Smith (Treasurer and Assistant Secretary of PSGS), and
  Donna K. Scrivens (Secretary of PSGS) pursuant to which each officer shall be
  employed for two years with certain benefits upon early termination, demotion
  or relocation. After consummation of the PSGS Merger, the directors and
  officers of PSGS at the Effective Time of the PSGS Merger will be insured
  under an extension of their current directors and officers liability policy.
  As of December 21, 1993, executive officers and directors of PSGS owned an
  aggregate of 81,151 shares of PSGS Stock. See "PSGS Merger-Interests of PSGS
  Management and Directors."

          Accounting Treatment. The PSGS Merger will be accounted for as a
  purchase of PSGS by NUI in accordance with generally accepted accounting
  principles. The regulatory process establishes rates on the basis of
  historical net book value; therefore, the underlying net assets of PSGS will,
  generally, be recorded as net assets of NUI at their historical net book value
  and the excess of the purchase price over the recorded net assets of PSGS,
  which amounts to approximately $6.8 million, will be added to utility plant as
  a "utility plant acquisition adjustment," which will be amortized over a
  thirty-year period that approximates the remaining useful life of the utility
  plant acquired. See "PSGS Merger-Accounting Treatment."

          Listing on New York Stock Exchange. The NYSE has authorized the

                                        11
<PAGE>



  listing of the shares of NUI Common Stock issuable in connection with the PSGS
  Merger upon official notice of issuance. It is a condition to each party's
  obligations to consummate the PSGS Merger that such shares of NUI Common Stock
  be approved for listing on the NYSE, subject to official notice of issuance.
  See "PSGS Merger-Basic Terms of Merger Agreement-Listing on New York Stock
  Exchange."

          Termination Payments and Expense Reimbursement. In the event that PSGS
  enters into an agreement or understanding to effect certain business
  combinations or asset sales to persons other than NUI or PSGS' Board of
  Directors recommends the acceptance of certain tender offers from persons
  other than NUI, PSGS has agreed to pay to NUI a fee and to reimburse NUI for
  certain expenses. PSGS does not intend to enter into any agreement or
  understanding which would obligate PSGS to pay such fee to NUI. See "PSGS
  Merger-Basic Terms of Merger Agreement-Certain Fees, Expenses and Related
  Matters."

          Comparison of Shareholder Rights. A discussion of significant
  differences in the rights of PSGS Stockholders under Delaware and New Jersey
  laws and under the certificate of incorporation and by-laws of PSGS and the
  certificate of incorporation and the by-laws of NUI is set forth under "PSGS
  Merger-Comparison of PSGS Stockholder Rights with NUI Shareholder Rights."

  Comparative Per Share Financial Information

          The following unaudited table sets forth certain per share information
  for NUI and PSGS, certain pro forma per share information for NUI after giving
  effect to the Mergers, and equivalent pro forma per share information for
  PSGS. Because the PSGS Merger will be accounted for as a purchase transaction,
  pro forma and equivalent per share income and dividend information is
  presented for only the most recent fiscal year for which financial information
  is available, which ended September 30, 1993. The data is based upon and
  should be read in conjunction with the NUI consolidated financial statements
  and the related notes thereto incorporated herein by reference; and the PSGS
  consolidated financial statements and the related notes thereto and the pro

   For the Fiscal Year Ended
   September 30, 1993:
   Net Income                         $1.70       $1.63       $1.74       $4.11
   Dividends                          $1.59       $1.59       $1.54       $4.01
   Net Book Value (as of fiscal
   year end)                         $14.93      $15.83      $38.48      $39.89

  (a)  The pro forma NUI data per NUI share gives effect to the PSGS Merger,
  pursuant to which the PSGS Stockholders will receive shares of NUI Common
  Stock equal in value to $71.50 for each share of PSGS Common Stock as set
  forth under "PSGS Merger-Basic Terms of the Merger Agreement-Conversion of
  PSGS Common Stock"; followed by the EGC Merger. The pro forma NUI data are
  prepared on the basis of accounting for the PSGS Merger as a purchase
  transaction. The regulatory process establishes rates on the basis of

                                        12
<PAGE>



  historical net book value; therefore, (i) the underlying net assets of PSGS
  will be recorded as assets of NUI at their historical net book value as of the
  date of the PSGS Merger, (ii) the funded status of the PSGS pension plan will
  be recognized by recording an asset equal to the excess of plan assets at fair
  value as compared with the projected benefit obligation as of the date of
  acquisition ($1.4 million), (iii) the excess of the Merger Consideration over
  the recorded net assets will be recorded as a "plant acquisition adjustment"
  (amounting to approximately $6.8 million) and (iv) the plant acquisition
  adjustment will be amortized over a thirty-year period (amounting to
  approximately $225,000 per year) that approximates the remaining useful life
  of the utility plant acquired; all in accordance with generally accepted
  accounting principles. Furthermore, the pro forma NUI net income per share for
  the fiscal year ended September 30, 1993 excludes merger expenses incurred by
  PSGS ($226,000, net of $117,000 of income tax), which would have equated to
  $0.03 per NUI share.

  (b)  Represents the pro forma equivalent of one share of PSGS Common Stock
  calculated by multiplying the pro forma per share NUI data by the conversion
  ratio of 2.520 ($71.50 divided by $28.375, the assumed Average Market Price
  per share of NUI Common Stock). Furthermore, the pro forma NUI net income per
  equivalent PSGS share for the fiscal year ended September 30, 1993 excludes
  merger expenses incurred by PSGS ($226,000, net of $117,000 of income tax),
  which would have equated to $0.07 per equivalent PSGS share. The actual
  conversion ratio may be greater (but not greater than 3.0) or less (but not
  less than 2.4) depending upon the actual Average Market Price. See "PSGS
  Merger-Basic Terms of Merger Agreement-Conversion of PSGS Common Stock." In
  the event that the actual conversion ratio is 3.0, the pro forma net income
  and dividends per equivalent PSGS share would be $4.83 and $4.77,
  respectively, for the fiscal year ended September 30, 1993 and the net book
  value per PSGS equivalent share would be $46.89 at September 30, 1993. In the
  event that the actual conversion ratio is 2.4, the pro forma net income and
  dividends per equivalent PSGS share would be $3.93 and $3.82, respectively,
  for the fiscal year ended September 30, 1993 and the net book value per PSGS
  equivalent share would be $38.12 at September 30, 1993. 

          The NUI Common Stock is listed on the NYSE and is traded under the
  symbol NUI.

          The following sets forth the closing market price per share for NUI
  Common Stock and the NUI closing market price per equivalent PSGS share on
  June 23, 1993, the last trading day before the announcement of the preliminary
  agreement between NUI and PSGS with respect to the PSGS Merger; on July 26,
  1993, the last trading day before the announcement of the signing of the
  Merger Agreement; and on January 7, 1994. There is no established public
  trading market for the PSGS Common Stock, therefore no PSGS Common Stock
  market price information is included herein.

  Stock by the conversion ratio of 2.520 ($71.50 divided by $28.375, the assumed
  Average Market Price per share of NUI Common Stock). The actual conversion
  ratio may be greater (but not greater than 3.0) or less (but not less than
  2.4) depending upon the actual Average Market Price. See "PSGS Merger-Basic
  Terms of Merger Agreement-Conversion of PSGS Common Stock." In the event that
  the actual conversion ratio is 3.0, the NUI market price per equivalent PSGS
  share would be $79.126 as of June 23, 1993, $87.001 as of July 26, 1993, and
  $78.00 as of January 7, 1994. In the event that the actual conversion ratio is
  2.4, the NUI market price per equivalent PSGS share would be $63.299 as of
  June 23, 1993, $69.599 as of July 26, 1993, and $62.40 as of January 7, 1994.

  INTRODUCTION

  The Parties

          NUI Corporation. NUI and its subsidiaries are engaged primarily in the
  distribution of natural gas in New Jersey and Florida. The principal executive
  offices of NUI are located at 550 Route 202-206, Box 760, Bedminster, NJ
  07921-0760; telephone: (908) 781-0500.

          NUI is an exempt public utility holding company under the Public
  Utility Holding Company Act of 1935 (the "PUHCA"). NUI was incorporated in New
  Jersey in 1969. NUI's principal operating subsidiary, Elizabethtown Gas
  Company, a New Jersey corporation ("EGC"), was organized in 1855. NUI
  currently serves approximately 320,000 customers in two states. The New Jersey
  Division does business as Elizabethtown Gas Company and the Florida Division
  does business as City Gas Company of Florida.

          Pennsylvania & Southern Gas Company. PSGS is engaged in the sale and
  distribution of natural gas to residential, commercial and industrial
  customers within prescribed areas of Maryland, New York, North Carolina and
  Pennsylvania. The principal executive offices of PSGS are located at 102
  Desmond Street, Sayre, PA  18840; telephone (717) 888-6600.

          PSGS was incorporated in Delaware on April 20, 1928. PSGS currently
  serves approximately 20,221 customers in four states.

  PSGS Stockholders Meeting

          Purpose of the Meeting. The purposes of the special meeting of PSGS
  Stockholders (the "PSGS Special Meeting") are (a) to consider and act upon a
  proposal to approve and adopt the Merger Agreement and (b) to transact such
  other business as may properly be brought before the PSGS Special Meeting or
  any adjournments thereof.

          Date, Time and Place of Meeting. The PSGS Special Meeting will be held
  on February 10, 1994 at 9:30 a.m., local time, at the Doubletree Hotel, Broad
  Street at Locust, Philadelphia, Pennsylvania.

          Record Date; Shareholders Entitled to Vote and Required Vote. Only
  holders of record of PSGS Common Stock at the close of business on January 11,
  1994 (the "PSGS Record Date") will be entitled to notice of, and to vote at,
  the PSGS Special Meeting. At such date there were 235,857 shares of PSGS
  Common Stock outstanding and entitled to vote. The affirmative vote of a
  majority of the outstanding shares of PSGS Common Stock is required to approve
  and adopt the Merger Agreement. The executive officers and directors of PSGS,
  in the aggregate, beneficially own 32% of the PSGS Common Stock outstanding as
  of the PSGS Record Date. Such persons have informed PSGS that all such shares
  over which they hold voting power will be voted for approval of the Merger
  Agreement. A majority of the issued and outstanding shares of PSGS Common
  Stock, represented in person or by proxy, shall constitute a quorum at the
  PSGS Special Meeting.

          Solicitation, Revocation and Use of Proxies. Shares of PSGS Common
  Stock represented by all properly executed proxies received in time for the
  PSGS Special Meeting will be voted at such meeting in the manner specified by
  the holders thereof. Shares represented by proxies which do not contain voting
  instructions will be voted in favor of approval and adoption of the Merger
  Agreement. It is not expected that any matter other than the Merger Agreement

                                        19
<PAGE>



  will be brought before the PSGS Special Meeting. If, however, other matters
  are properly presented, the persons named as proxies will vote in accordance
  with their judgment with respect to such matters.

          PSGS Stockholders are requested to complete, sign, date and return
  promptly the enclosed proxy in the postage paid envelope provided for this
  purpose in order to assure that their shares are voted. A proxy may be revoked
  at any time prior to the exercise of the authority granted thereunder.
  Revocation may be accomplished by granting of a later proxy with respect to
  the same shares or by written notice to the Secretary of PSGS at any time
  prior to the vote on the PSGS Merger. Mere attendance at the PSGS Special
  Meeting will not in itself revoke a proxy.

          PSGS will bear the cost of the solicitation of proxies from its
  stockholders. In addition to solicitation by mail, officers and regular
  employees of PSGS, who will receive no compensation in excess of their regular
  salaries for their services in connection therewith, may solicit proxies by
  telephone, telegram or otherwise.

          Appraisal Rights. Holders of PSGS Common Stock will be entitled to
  appraisal rights under Delaware law, if such rights are properly perfected,
  because such persons hold stock of a constituent corporation in a merger which
  is neither listed on a national securities exchange nor held of record by more
  than 2,000 holders. See "Appraisal Rights" for a discussion of the procedures
  that must be followed by holders of PSGS Common Stock in order to exercise
  appraisal rights.

          Other Business. The PSGS Board of Directors knows of no matters to be

                               THE PROPOSED MERGERS

  Background of and Reasons for the PSGS Merger

          PSGS. On November 1, 1992, Mr. Paul W. Ware, a member of the PSGS
  Board of Directors, notified each other member of the PSGS Board by telephone
  of his parents' decision to seek a buyer for their holdings in PSGS. At
  approximately the same time, PSGS received a letter from New York State
  Electric & Gas Corporation ("NYSEG") suggesting a potential alliance between
  PSGS and NYSEG. On November 4, 1992, a teleconference meeting of the PSGS
  Executive Committee of the Board of Directors was held in which the Committee
  recommended that the NYSEG inquiry be placed on the agenda for the full
  meeting of the Board of Directors of PSGS scheduled for November 18, 1992. At
  this Committee meeting Mr. Irvin Saltzman reported that he had been contacted
  by Mr. G. Clay von Seldeneck who had identified himself as a financial advisor
  for holders of PSGS Common Stock held of record and beneficially by (i) John
  Ware, III, and (ii) Penco Savings and Profit Sharing Plan (for purposes of
  this Proxy Statement being called herein collectively, the "Ware Shares")
  which represented approximately 25% of the total outstanding PSGS Common
  Stock. Mr. von Seldeneck had informed Mr. Saltzman that he was seeking
  purchasers for the Ware Shares and that he was interested in marketing Mr.
  Saltzman's holdings. Mr. Saltzman informed the Committee that he had refused
  Mr. von Seldeneck's request. 

          Each member of the PSGS Board of Directors then received a letter
  dated November 13, 1992 from Mrs. Marian S. Ware and Mr. Terry Hunt (Trustee
  of the Penco Savings and Profit Sharing Plan) in which the Ware's previously
  announced intention of selling their PSGS Common Stock was formally announced.
  This letter also included a request that the holders of the Ware Shares be

                                        22
<PAGE>



  permitted to discuss with the full PSGS Board of Directors the possibility of
  seeking buyers for the entire company. 

          On November 18, 1992 the PSGS Board of Directors held its regularly
  scheduled quarterly meeting. At this meeting, the PSGS Board of Directors
  directed PSGS management to inform both NYSEG and Mrs. Ware and Mr. Hunt that
  the PSGS Board of Directors was not seeking a buyer for the entire company and
  they had not retained any agent to do so. 

          In December of 1992 Mr. Paul W. Ware informed Mr. Lyle C. Motley, Jr.,
  CEO of PSGS, that the holders of the Ware Shares had hired Mr. G. Clay von
  Seldeneck of Snyder & Company of Philadelphia, Pennsylvania to be their agent
  in connection with the proposed sale of their shares. 

          On February 11, 1993 the PSGS Board of Directors held its regularly
  scheduled quarterly meeting. At this meeting Mr. Craig L. Godshall, attorney
  for certain of the holders of the Ware Shares, was given an opportunity in
  accordance with a request from certain of the holders of the Ware Shares, to
  address the PSGS Board of Directors. Mr. Godshall informed the PSGS Board of
  Directors that the Ware Shares were being offered for sale to assist certain
  family members in their financial planning and diversification of investments.
  The agent for the Ware Shares, Mr. von Seldeneck, had solicited in excess of
  twenty potential buyers, four of which stated their interest in holding
  discussions with PSGS. Mr. Godshall conveyed the request of the holders of the
  Ware Shares that PSGS management meet with these prospective buyers of the
  Ware Shares which included South Jersey Industries, Incorporated ("SJII"),
  NYSEG, NUI, and United Cities Gas Company ("UCGC"). The PSGS Board of
  Directors determined that whereas the holders of the Ware Shares were
  shareholders of long standing with PSGS, management should meet with the
  prospective buyers to discuss the sale of the Ware Shares. The PSGS Board of
  Directors maintained its position that the entire company was not for sale and
  that participation in these meetings should not be interpreted to the
  contrary. The issue of a sale of a portion of the PSGS business was not raised
  since the PSGS Board of Directors authorized participation in these meetings
  solely to facilitate the sale of the Ware Shares. Mr. George Failey, Chairman
  of the Board for PSGS, and Mr. Motley were designated as the representatives
  for PSGS at these meetings. 

          On February 17, 1993 Mr. Failey and Mr. Motley met in Philadelphia,
  Pennsylvania with representatives of NUI regarding the sale of the Ware
  Shares. On February 18, 1993 Mr. Failey and Mr. Motley met in Philadelphia,
  Pennsylvania with representatives of SJII regarding the sale of the Ware
  Shares. Discussions during this meeting were limited due to the refusal of
  SJII to execute PSGS's standard confidentiality letter. On February 23, 1993
  Mr. Failey and Mr. Motley met in Pittsburgh, Pennsylvania with representatives
  of UCGC regarding the sale of the Ware Shares. On March 9, 1993 Mr. Failey and
  Mr. Motley met in Elmira, New York with representatives of NYSEG regarding the
  sale of the Ware Shares. On March 11, 1993, at the request of Mr. von
  Seldeneck on behalf of the holders of the Ware Shares, a fifth meeting was
  held by Mr. Failey and Mr. Motley in Pittsburgh, Pennsylvania with
  representatives of Public Service of North Carolina ("PSNC") regarding the
  sale of the Ware Shares. At each of these meetings the representatives of the
  companies other than PSGS inquired as to the possible purchase of all of the
  outstanding PSGS Common Stock. Messrs. Failey and Motley responded to each
  that PSGS was not for sale and that they were attending these meetings solely
  to facilitate the sale of the Ware Shares.

          Following the March 11, 1993 meeting with PSNC, PSGS did not contact

                                        23
<PAGE>



  or make any effort to contact any of these entities because the PSGS Board of
  Directors had taken the position that PSGS was not for sale and that these
  meetings had been held to facilitate the sale of the Ware Shares. PSGS heard
  nothing from any of the five companies until Mr. Failey received an
  unsolicited letter dated April 6, 1993 from William F. Ryan, President and CEO
  of SJII (the "SJII Letter"). The SJII Letter proposed that SJII acquire all of
  the outstanding PSGS Common Stock in exchange for SJII common stock in the
  exchange ratio of approximately 1.36 shares of SJII common stock for each
  share of PSGS Common Stock. The SJII Letter stated that based on PSGS' book
  value at September 30, 1992, this proposal would have a value of $38.28 per
  share. The SJII Letter also indicated that it would be the intent of SJII to
  maintain PSGS as a distinct wholly-owned subsidiary retaining both management
  and non-management employees. The SJII Letter stated that the proposal
  contained therein would terminate on April 30, 1993 if not previously accepted
  by PSGS. Mr. Motley requested, and Mr. Ryan agreed to, an extension of the
  April 30, 1993 deadline to May 12, 1993, the date of the next regularly
  scheduled meeting of the PSGS Board of Directors.

          PSGS received an unsolicited letter dated April 8, 1993 (the "NUI
  Letter"), from Mr. John Kean, President of NUI, in which he informed Mr.
  Motley of NUI's interest in acquiring all of the outstanding PSGS Common
  Stock. The NUI Letter indicated, however, that the indication of proposed
  value was based on a preliminary review of PSGS and that NUI needed to visit
  relevant operations of PSGS and to review certain additional information. The
  NUI Letter indicated a proposed value of $80.00 per share for all of the
  outstanding PSGS Common Stock. The NUI Letter proposed an exchange of PSGS
  Common Stock for NUI Common Stock and indicated that NUI's business plan
  included the acquisition of gas distribution companies with the primary goal
  of coordinating gas supply requirements. The NUI Letter also indicated that
  each utility acquired by NUI would maintain its own identity, management and
  employees and that NUI would provide all capital raising functions. 

          On April 13, 1993 the Executive Committee of the PSGS Board of
  Directors met by teleconference to discuss and review proposals which had been
  received from NUI and SJII regarding the acquisition of all of the outstanding
  PSGS Common Stock. The Committee instructed Mr. Failey and Mr. Motley to
  conduct further discussions with NUI and SJII with respect to these proposals.
  During this period PSGS received no communications from UCGC, NYSEG or PSNC.

          On April 21, 1993 the Executive Committee of the PSGS Board of
  Directors met by teleconference. It was reported that an individual poll of
  each member of the Board of Directors had resulted in unanimous support in
  proceeding with the discussions with NUI based upon the attractiveness of the
  offer contained in the NUI Letter. The Executive Committee instructed
  management to retain an investment banker. On May 3, 1993 PSGS retained
  Berwind Financial Group, Incorporated ("Berwind") as the PSGS investment
  banker. 

          On May 12, 1993 the PSGS Board of Directors held its regularly
  scheduled quarterly meeting. Representatives of Berwind attended this session
  to discuss procedures for pursuing the inquiries from NUI and SJII. Following
  this meeting, Berwind advised SJII that the value per share contained in the
  SJII Letter was less than other indications of interest to date. Throughout
  the next several weeks Berwind held discussions with SJII but no agreement was
  reached on the issue of execution of a confidentiality agreement to cover
  material disclosed in due diligence. Counsel for PSGS was therefore instructed
  to terminate discussions with SJII by letter dated June 9, 1993 due to the
  lack of a confidentiality agreement.

                                        24
<PAGE>



          Throughout the month of June 1993, Berwind negotiated, at the
  direction of Messrs. Failey and Motley, the terms of a Letter of Intent (the
  "Letter of Intent") with representatives of NUI. During this same period, NUI
  conducted the review of PSGS and its operations that NUI had indicated in the
  NUI Letter was necessary in order for NUI to determine the actual price per
  share of PSGS common stock that NUI would offer to the PSGS Board of
  Directors. As a result of these investigations and due diligence, the
  consideration for the PSGS Common Stock was revised to $71.50 per share
  payable in NUI Common Stock. Pursuant to the terms of the Letter of Intent,
  each PSGS Stockholder would receive no less than 2.4 and no more than 3.0
  shares of NUI Common Stock in exchange for each share of PSGS Common Stock
  held. On June 23, 1993 all members but one of the PSGS Board of Directors
  participated in a special meeting by teleconference at which those
  participating unanimously approved the execution of the Letter of Intent with
  NUI for the reasons described under "-Recommendations of the PSGS Board of
  Directors." On June 24, 1993 the Letter of Intent for the PSGS Merger was
  executed by Mr. John Kean of NUI and Mr. Lyle C. Motley, Jr. of PSGS.

          On July 27, 1993 a special meeting of the PSGS Board of Directors was
  held at which all members of the Board were present. Berwind made a
  presentation to the Board during which it summarized and reviewed the results
  of its due diligence study of NUI. Berwind reported that it believed the stock
  exchange ratio offered by NUI to be fair as of July 27, 1993 from a financial
  point of view. The PSGS Board of Directors made no recommendations to Berwind.
  (see "The Proposed Mergers-Opinion of PSGS Financial Advisor"). PSGS counsel
  reviewed with the Board the Agreement and Plan of Merger and, in particular,
  the tax aspects of the structure of the transaction. Following discussion, the
  PSGS Board of Directors unanimously approved the merger of PSGS with and into
  NUI pursuant to the terms and conditions of the Agreement and Plan of Merger.
  The Agreement and Plan of Merger was executed on July 28, 1993 by Mr. John
  Kean of NUI and Mr. Lyle C. Motley, Jr. of PSGS.

          In entering into the negotiations leading up to the PSGS Merger, the
  management and the Board of Directors of PSGS concluded that the PSGS Merger
  would be advantageous to PSGS Stockholders and customers as well as the states
  and communities served by PSGS. The management and Board of Directors of PSGS
  believed that by creating a larger combined company, the PSGS Merger would
  help increase gas purchasing power and improve access for PSGS to capital
  markets. The management and Board of Directors of PSGS noted important changes
  and trends in the industry, including changes in gas supply and pricing. With
  the changes taking place in the gas industry, management and the Board of
  Directors of PSGS believed that the larger and more geographically diversified
  a gas company is, the better it will be able to compete for gas supplies,
  capital and managerial talent. 

          NUI. In entering into the negotiations leading up to the PSGS Merger,
  the management and Board of Directors of NUI concluded that the PSGS Merger
  would be advantageous to shareholders and customers of NUI and EGC, as well as
  the communities they serve. NUI, in accordance with its business plan, is
  concentrating on customer growth and the profitability of its gas distribution
  business. Growth opportunities could include the acquisition of additional gas
  distribution companies, the development of new franchises and the management
  of certain service requirements of other utilities on a contract basis. NUI's
  strategy involves assembling, as opportunities become available, a natural gas
  distribution system in several states, while maintaining a balanced capital
  structure. From time to time, NUI reviews acquisition opportunities and, when
  requested, submits acquisition proposals.


                                        25
<PAGE>



          NUI's plan takes advantage of opportunities presented by the
  restructuring of interstate natural gas pipeline operations and the increase
  in supply alternatives. Traditionally, interstate pipelines were wholesalers
  of natural gas to local distribution companies and generally did not provide
  separate transportation or other services for specific customers. In 1985, the
  Federal Energy Regulatory Commission (the "FERC") adopted Order No. 436 that
  encouraged interstate pipelines to make transportation of gas available to
  customers on a non-discriminatory basis. Such voluntary "open access" by
  certain interstate pipelines enhanced the opportunity for NUI, other local gas
  distribution companies and industrial customers to purchase natural gas
  directly from gas producers and others. In 1992, the FERC issued Order No. 636
  that, among other things, mandated the separation or "unbundling" of
  interstate pipeline sales, transportation and storage services and established
  guidelines for capacity management effective in 1993. Order No. 636 increased
  the opportunity for local gas distribution companies and industrial customers
  to purchase natural gas from alternative sources, while increasing the
  potential business and regulatory risk borne by a local gas distribution
  company with respect to the acquisition and management of natural gas
  services.

          The business plan envisions a natural gas distribution system in
  which, among other matters, local managements conduct the marketing, customer
  service and distribution operations in each state served, with management of
  gas supply and access to capital markets coordinated centrally. 

          The PSGS Merger fits within the NUI business plan. By managing the
  business risks, including coordinating the management of PSGS's gas supply and
  access to capital markets centrally, NUI expects to add value to the business
  within the acquired franchise areas through accelerating the rate of growth
  and enhancing long term profitability.

  Recommendations of the PSGS Board of Directors

          THE BOARD OF DIRECTORS OF PSGS BELIEVES THAT THE TERMS OF THE PSGS
  MERGER ARE FAIR TO, AND IN THE BEST INTERESTS OF, PSGS AND THE PSGS
  STOCKHOLDERS. ACCORDINGLY, THE PSGS BOARD OF DIRECTORS HAS APPROVED THE MERGER
  AGREEMENT AND UNANIMOUSLY RECOMMENDS THAT HOLDERS OF PSGS COMMON STOCK VOTE
  FOR THE APPROVAL OF THE MERGER AGREEMENT.

          At a special meeting of the Board of Directors of PSGS held on July
  27, 1993, the Board of Directors of PSGS approved the Merger Agreement. This
  approval followed, and was based upon discussions at, meetings of the
  Executive Committee of the Board of Directors of PSGS to consider matters
  relating to the PSGS Merger held on April 13, 1993, April 21, 1993, April 26,
  1993, May 11, 1993, June 15, 1993 and June 18, 1993 and meetings of the Board
  of Directors held on February 11, 1993, May 12, 1993, June 23, 1993, and July
  27, 1993. In arriving at its conclusion, the PSGS Board of Directors received
  presentations from, and reviewed carefully, the terms and conditions of the
  Merger Agreement with PSGS's management, counsel and investment banker.
  Thereafter, the Board of Directors of PSGS unanimously approved the Merger
  Agreement. Such determination by the Board of Directors of PSGS was based on
  the following factors: (i) the significant increase in pro forma earnings and
  dividends per equivalent PSGS share following the PSGS Merger which, in the
  opinion of the PSGS Board of Directors, would enhance the value of the
  investment of the PSGS stockholders and would be in their best interests, and
  the increased asset base of NUI following the PSGS Merger as compared with the
  PSGS asset base which, in the opinion of the PSGS Board of Directors, can
  provide a competitive advantage relative to other competing gas distribution

                                        26
<PAGE>



  businesses (see the NUI Pro Forma Financial Information including the related
  notes thereto, which are included elsewhere in this Proxy
  Statement/Prospectus); (ii) the relative market value of NUI Common Stock as
  compared with the last known bid price of PSGS Common Stock which, when
  considered in conjunction with all other factors indicated herein (see "-
  Opinion of PSGS Financial Advisor"), support the opinion that the
  consideration to be paid by NUI is fair as of January 10, 1994 to the PSGS
  shareholders from a financial point of view because the exchange ratio
  provides a premium to PSGS Stockholders which is not believed to be
  excessively dilutive to NUI Stockholders and (iii) the opinion of PSGS's
  investment banker, Berwind, that the consideration to be paid by NUI is fair
  as of January 10, 1994 to the PSGS Stockholders from a financial point of
  view. In assessing the fairness of the PSGS Merger from a financial point of
  view, Berwind reviewed with the Board of Directors during their July 27, 1993
  meeting various data and analyses, including: (i) the changes in the amount of
  earnings, book value and dividends represented by 1.0 shares of PSGS Common
  Stock prior to the PSGS Merger and 2.4 to 3.0 shares of NUI Common Stock after
  the PSGS Merger; (ii) comparable companies and comparable transaction analyses
  relative to PSGS and NUI, including multiples of book value, earnings and
  revenues as well as market price premiums implied by the Merger Consideration;
  and (iii) the PSGS discounted dividend analysis whereby Berwind estimated the
  present value of future dividends that PSGS could produce over a five-year
  period under different assumptions as to dividend payout levels, if PSGS
  performed in accordance with management's forecasts and certain variants
  thereof. See "The Proposed Mergers-Opinion of PSGS Financial Advisor." Berwind
  reconfirmed this opinion as of the date of this Proxy Statement/Prospectus. A
  copy of this opinion, dated the date of this Proxy Statement/Prospectus, is
  attached hereto as Annex B. 

          The Directors of PSGS evaluated the factors listed above in light of
  their knowledge of the business and operations of PSGS and NUI and their
  business judgment. The PSGS Board of Directors considered these factors in
  their totality and did not quantify or otherwise attempt to assign relative
  weights to the specific factors considered in making its determinations.

  Opinion of PSGS Financial Advisor

          Background. PSGS retained Berwind on May 3, 1993 to advise it as to
  the fairness from a financial point of view to the PSGS Stockholders of the
  Merger Consideration. The selection of Berwind to act as advisor to PSGS was
  based upon the experience, qualifications and reputation of Berwind. Prior to
  rendering the fairness opinion, summarized below, Berwind assisted PSGS in the
  negotiation of the terms of the PSGS Merger and related transactions.

          Fairness Opinion. On July 27, 1993, at the meeting at which the PSGS
  Board of Directors approved and adopted the Merger Agreement, Berwind
  delivered an oral opinion to the PSGS Board of Directors that as of such date
  the PSGS Merger was fair to the PSGS Stockholders from a financial point of
  view. This opinion was confirmed in writing on January 10, 1994. Berwind's
  opinion is directed to the PSGS Board of Directors only and is directed only
  to the Merger Consideration, and does not constitute a recommendation to any
  PSGS Stockholder as to how such stockholder should vote at the PSGS Special
  Meeting. PSGS Stockholders are urged to read carefully the full text of
  Berwind's opinion, a copy of which is attached as Annex B to this Proxy
  Statement/Prospectus and is incorporated herein by reference.

          In arriving at its opinion, Berwind among other things: (i) reviewed
  certain publicly available business and financial information relating to PSGS

                                        27
<PAGE>



  and NUI, including (A) each of PSGS's and NUI's Annual Reports to Shareholders
  for the fiscal years ended September 30, 1988 through 1993, NUI's Annual
  Reports on Form 10-K for the fiscal years ended September 30, 1988 through
  1993 and Quarterly Reports to shareholders for the quarters ended December 31,
  1992, March 31, 1993, and June 30, 1993; (B) the reported prices, trading
  activity and dividends paid for PSGS Common Stock and NUI Common Stock over
  the previous three-year period; (ii) held discussions with PSGS's senior
  management and Board of Directors; (iii) considered the terms and conditions
  of the proposed transaction between PSGS and NUI as compared with the terms
  and conditions of comparable mergers and acquisitions; (iv) read the
  information with respect to the proposed transaction between PSGS and NUI as
  set forth in the Merger Agreement; (v) held discussions with NUI's senior
  management relating to NUI's financial condition, results of operations and
  prospects and (vi) conducted such other financial analyses, studies and
  investigations as it deemed appropriate.

          Berwind noted that its opinion is given in reliance on information and
  representations made or given by PSGS and NUI and their respective officers,
  directors, auditors, counsel and other agents, and on filings, releases and
  other information issued by PSGS and NUI including financial statements,
  financial projections, and stock price data as well as certain information
  from recognized independent sources. Berwind has not independently verified
  the information concerning PSGS and NUI or other data which it considered in
  its review, and, for purposes of its opinion, Berwind has assumed and relied
  upon the accuracy and completeness of all such information and data.
  Assumptions made by Berwind in arriving at its opinion are listed in the full
  text of its opinion, a copy of which is attached to this Proxy
  Statement/Prospectus as Annex B.

          A summary of Berwind's financial analysis is set forth below.

          Pro Forma Contribution Analysis. Berwind analyzed the changes in the
  amount of earnings, book value, and dividends represented by 1.0 shares of
  PSGS Common Stock prior to the PSGS Merger and 2.4 to 3.0 shares of NUI Common
  Stock after the PSGS Merger. The analysis indicated, among other things, the
  PSGS Merger would result as of September 30, 1993 in an increase to earnings
  per share of 123.2% to 174.5%, a change to book value per share ranging from a
  reduction of 1.0% to an increase of 21.8% and an increase in indicated
  dividends of 128.6% to 185.7% to PSGS. On a pro forma combined basis, the
  analysis indicated PSGS would contribute approximately 2.9%, 6.5%, and 5.9% to
  the combined companies' earnings, equity and assets, respectively for fiscal
  year 1993. Based on an exchange ratio of 2.4 to 3.0 shares of NUI for each
  share of PSGS, existing PSGS shareholders would own 6.45% to 7.94% of the
  combined companies.

          Comparable Companies and Comparable Acquisition Analyses. Berwind
  compared the financial performance of PSGS based on various measures of
  earnings performance, capitalization, revenues and dividend growth to that of
  a peer group of natural gas distribution companies that Berwind deemed
  comparable, including Allegheny & Western Energy Corp.; Berkshire Gas Company;
  Cascade Natural Gas Corp.; Chesapeake Utilities Corporation; Colonial Gas
  Company; Connecticut Energy Corporation; Connecticut Natural Gas Company;
  Corning Natural Gas Corp.; EnergyNorth Inc.; Great Falls Gas Corp.;
  Pennsylvania Enterprises; Providence Energy Corporation; Public Service Co. of
  North Carolina; Roanoke Gas Company; United Cities Gas Company; and Valley
  Resources. This analysis showed, among other things, that as of January 10,
  1994 PSGS' latest twelve-month return on assets and equity were 1.43% and
  4.53%, respectively, compared to the median of 3.41% and 11.10%, respectively,

                                        28
<PAGE>



  for the peer group; its asset-to-equity ratio was 316.45% compared to the
  median of 314.99% for the peer group; its price-to-earnings ratio was 22.7
  compared to the median of 15.7 for the peer group; its price-to-book ratio was
  1.03 compared to the median of 1.64 for the peer group; and its dividend yield
  was 4.25% compared to the median of 5.15% for the peer group prior to
  announcement of the Merger.

          Berwind also compared the financial performance of NUI based on
  various financial measures of earnings performance, capitalization revenues
  and dividend growth to that of a peer group of natural gas distribution
  companies that Berwind deemed comparable, including Atmos Energy Corp.;
  Connecticut Energy Corp.; Connecticut Natural Gas Corp.; Energen Corp.;
  Indiana Energy Inc.; Laclede Gas Co.; New Jersey Resources Corp.; Northwest
  Natural Gas Co.; Piedmont Natural Gas Co.; Public Service Co of NC Inc.; South
  Jersey Industries Inc.; United Cities Gas Co.; Washington Energy Company; and
  Yankee Energy Systems Inc. This analysis showed, among other things, that as
  of January 10, 1994, NUI's latest twelve-month return on assets and equity
  were 2.84% and 11.28%, respectively, compared to the median of 4.09% and
  11.77%, respectively, for the peer group; its asset-to-equity ratio was
  397.55% compared to the median of 283.35% for the peer group; its
  price-to-earnings ratio was 15.3 compared to the median of 14.4 for the peer
  group; its price-to-book ratio was 1.74 compared to the median of 1.80 for the
  peer group and its dividend yield was 6.15% compared to the median of 4.95%
  for the peer group prior to announcement of the Merger.

          The above indicated pro forma contribution and comparable companies
  analyses provide support that, when considered in conjunction with all other
  factors indicated herein, the consideration to be paid by NUI is fair as of
  January 10, 1994 to the PSGS Stockholders from a financial point of view
  because (i) the combined companies' earnings, equity and assets will increase;
  and (ii) receipt of NUI shares in exchange for PSGS shares will enhance the
  value of the investment of the PSGS Stockholders as indicated through the
  above comparable analyses.

          Berwind also compared the multiples of book value, earnings and
  revenues as well as market price premiums, implied by the Merger
  Consideration, with the multiples paid in recent acquisitions of natural gas
  distribution and natural gas transmission and distribution companies that
  Berwind deemed comparable. The transactions deemed comparable by Berwind
  included acquisitions announced during 1987 through the present. Recently
  announced selected transactions included (acquiror/acquiree): Wisconsin Energy
  Corp./Wisconsin Southern Gas Co.; and Torch Energy/Panda Resources Inc. This
  analysis showed, among other things, a range of percentage premiums at the
  date the announcement of the transaction of (i) price offered as a multiple of
  latest twelve-month earnings of 33.9 for the proposed transaction compared to
  a range of 9.6 to 36.5 for the selected transactions reviewed; (ii) price
  offered as a multiple of book value of 1.7 for the proposed transaction
  compared to a range of 1.6 to 4.1 for the selected transactions reviewed and
  (iii) price offered as a premium over the market price of the acquiree's share
  price (four weeks prior to announcement) of 81.0% compared to a range of -7.8%
  to 81.2% for the selected transactions reviewed. 

          For purposes of the above analyses, Berwind used a $39.50 price per
  share of PSGS Common Stock, which was the last known bid price of PSGS Common
  Stock. 

          With respect to the price offered as a multiple of book value,
  relative to comparable companies'  acquisition values as a percentage of book

                                        29
<PAGE>



  value, the PSGS multiple was at the low end of the range. Berwind ascribed
  this result to PSGS' profitability relative to that of comparable acquisition
  targets. For example, Berwind found that the PSGS net income to revenue was
  1.6% for the latest twelve month period as of July 27, 1993, while the PSGS
  comparable acquisition targets' median and averages were 2.9% and 4.3%,
  respectively. These data suggest that the PSGS asset base and resultant book
  value was underutilized in generating earnings and that a lower multiple to
  book value could therefore reasonably be ascribed to PSGS in a fair valuation.
  Berwind also noted that the offering price relative to earnings indicated a
  multiple of 33.9x for the latest twelve month period as of July 27, 1993,
  while the PSGS comparable acquisition targets' median and averages were 14.5
  and 17.9, respectively. However, no company or transaction used in this
  analysis is identical to PSGS, NUI or the PSGS Merger. Accordingly, an
  analysis of the results of the foregoing is not strictly mathematical; rather,
  it involves complex considerations and judgements concerning differences in
  financial and operating characteristics of the companies and other factors
  that would affect the public trading values of the companies to which they are
  being compared.

          For purposes of the above analyses, Berwind used a $39.50 price per
  share of PSGS Common Stock, which was the last known bid price of PSGS Common
  Stock.

          Discounted Dividend Analysis. Using discounted dividend analysis,
  Berwind estimated the present value of the future dividend streams that PSGS
  could produce over a five year period under different assumptions as to
  dividend payout levels, if PSGS performed in accordance with management's
  forecasts and certain variants thereof. Berwind also estimated the terminal
  value for PSGS's Common Stock after the five year period by applying a range
  of earnings multiples from 8 to 16 to PSGS terminal year earnings. The range
  of multiples used reflected a variety of scenarios regarding the growth and
  profitability prospects of PSGS. The dividend streams and terminal values were
  then discounted to the present using discount rates ranging from 8% to 18%
  which reflect different assumptions regarding the required rates of return by
  holders or prospective buyers of PSGS's common equity. This analysis indicated
  a net present value of PSGS shares ranging from $18.61 to $58.44 based on
  these various terminal values and discount rates.

          Berwind also calculated and applied a weighted average cost of capital
  discount rate to the cash flows, with certain variants utilized to establish a
  range of values for PSGS.

          Although the summary set forth above describes all the material
  provisions of the analysis performed by Berwind, it is not intended to be a
  complete description of all the analyses performed by Berwind. The preparation
  of a fairness opinion is not necessarily susceptible to partial analysis or
  summary description. Berwind believes that its analyses and the summary set
  forth above must be considered as a whole and that selecting portions of the
  analyses, without considering all factors and analyses, would create an
  incomplete view of the processes underlying the analyses set forth in
  Berwind's opinion and presentation to PSGS. In addition, Berwind may have
  given various analyses more or less weight than other analyses, and may have
  deemed various assumptions more or less probable than other assumptions so
  that the ranges of valuations resulting from any particular analyses described
  above should not be interpreted as Berwind's view of the actual value of PSGS
  or NUI. That any specific analysis has been referred to in the summary above
  is not meant to indicate that such analysis was given greater weight than any
  other analysis.

                                        30
<PAGE>



          Additionally, in performing its analyses, Berwind made numerous
  assumptions with respect to industry performance, general business and
  economic conditions and other matters, many of which are beyond the control of
  PSGS or NUI. The analyses performed by Berwind are not necessarily indicative
  of actual values or actual future results, which may be significantly more or
  less favorable than suggested by the analyses. Such analyses were prepared
  solely as part of Berwind's review of the fairness from a financial point of
  view of the Merger Consideration to PSGS's Stockholders. The analyses do not
  purport to be appraisals or to reflect the prices at which a company might
  actually be sold or the prices at which any securities may trade at the
  present time or at any time in the future. In addition, as described above,
  Berwind's opinion to PSGS was one of many factors taken into consideration by
  the PSGS Board of Directors in making its determination to approve the Merger
  Agreement.

          Berwind, as part of its investment banking business, regularly is
  engaged in the valuation of assets, securities and companies in connection
  with various types of asset and security transactions, including mergers,
  acquisitions, private placements, and valuations for various other purposes
  and in the determination of adequate consideration in such transactions.

          In a letter agreement dated May 3, 1993, PSGS retained Berwind to act
  as its financial advisor in connection with a potential merger involving PSGS
  and NUI. Pursuant to the letter agreement, PSGS agreed to pay Berwind for its
  services, including the rendering of a fairness opinion, a fee which totals
  $150,000 of which $15,000 was paid on acceptance of such letter agreement,
  $35,000 upon submission of the written fairness opinion and the balance at
  closing. Such letter agreement also provides that PSGS will indemnify Berwind
  and its affiliates and their respective employees and agents against certain
  expenses and liabilities arising out of the transactions contemplated by such
  letter agreement.

  Federal Income Tax Considerations

          Tax Consequences to PSGS Stockholders. In the opinion of Montgomery,
  McCracken, Walker & Rhoads ("PSGS Counsel"), the PSGS Merger will qualify for
  federal income tax purposes as a reorganization within the meaning of Section
  368 of the Internal Revenue Code of 1986, as amended (the "Code"); and,
  accordingly, no gain or loss will be recognized by the PSGS Stockholders upon
  their receipt of the NUI Common Stock in exchange for their PSGS Common Stock,
  except to the extent that cash is received in lieu of a fractional share of
  NUI Common Stock. For a more complete description of the federal income tax
  consequences of the PSGS Merger, see "PSGS Merger-Federal Income Tax
  Considerations." Because the tax consequences of the PSGS Merger under
  federal, state, local and foreign tax laws may vary, depending upon an
  individual taxpayer's particular situation, it is recommended that each PSGS
  Stockholder consult with his or her tax advisor regarding the applicable tax
  consequences of the PSGS Merger.

          Tax Consequences to NUI.

          PSGS Merger. In the opinion of Kaye, Scholer, Fierman, Hays & Handler
  ("NUI Counsel"), the PSGS Merger will qualify for Federal income tax purposes
  as a reorganization within the meaning of Section 368 of the Code and,
  accordingly, no gain or loss will be recognized by NUI or PSGS in connection
  with the acquisition of assets and assumption of liabilities resulting from
  the PSGS Merger. If the PSGS Merger so qualifies, then, in general, NUI's
  adjusted basis for Federal income tax purposes in the assets acquired in the

                                        31
<PAGE>



  PSGS Merger will be the same as PSGS's adjusted basis for Federal income tax
  purposes in such assets immediately prior to the PSGS Merger.

          EGC Merger. In the opinion of NUI Counsel, the EGC Merger will be
  treated, with respect to NUI and EGC, as a complete liquidation under Section
  332 of the Code. Thus, no gain or loss will be recognized by NUI upon receipt
  of the property and assumption of the liabilities of EGC. In addition, no gain
  or loss will be recognized by EGC as a consequence of the transfer of assets
  and liabilities to NUI. In general, NUI will have the same adjusted basis for
  Federal income tax purposes in the property it receives from EGC as a result
  of the liquidation as EGC had in such property immediately before the
  liquidation, assuming that the EGC Merger qualifies as a complete liquidation
  under Section 332 of the Code.

          THE FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR
  GENERAL INFORMATION ONLY. PSGS STOCKHOLDERS  ARE URGED TO CONSULT THEIR OWN
  TAX ADVISORS AS TO SPECIFIC TAX CONSEQUENCES TO THEM OF THE MERGERS INCLUDING
  TAX RETURN REPORTING REQUIREMENTS AND THE APPLICABILITY AND EFFECT OF FEDERAL,
  STATE, LOCAL, FOREIGN AND OTHER APPLICABLE TAX LAW. IT IS NOT A CONDITION TO
  THE CONSUMMATION OF ANY OF THE MERGERS THAT THE MERGERS HAVE THE FEDERAL TAX
  CONSEQUENCES DESCRIBED ABOVE.

                                    PSGS MERGER

  General

          The description of the Merger Agreement and certain related matters
  set forth below does not purport to be complete and is qualified in its
  entirety by reference to the text of the Merger Agreement, which is attached
  as Annex A to this Proxy Statement/Prospectus and is incorporated herein by
  reference.

          The Merger Agreement provides that, subject to the satisfaction or
  waiver of certain conditions, including but not limited to the receipt of all
  necessary regulatory approvals, other consents and the approval of the PSGS
  Stockholders, PSGS will be merged with and into NUI. As a result of the PSGS
  Merger, the separate corporate existence of PSGS will cease, and the PSGS
  Stockholders will receive shares of NUI Common Stock in exchange for their
  shares of PSGS Common Stock. See "PSGS Merger-Basic Terms of Merger Agreement-
  Conversion of PSGS Common Stock."

  Basic Terms of Merger Agreement

          Conversion of PSGS Common Stock. At the time the PSGS Merger becomes
  effective (the "Effective Time of the PSGS Merger") (see "PSGS Merger-
  Effective Time of the PSGS Merger"), each outstanding share of PSGS Common
  Stock (other than shares owned by NUI, PSGS or any of their respective
  subsidiaries which will be cancelled (the "Cancelled Shares") or shares held
  by PSGS Stockholders who perfect appraisal rights' under Delaware law (the
  "PSGS Dissenting Shares"; see "Appraisal Rights") will be converted into the
  right to receive the number of shares of NUI Common Stock, or fraction thereof
  rounded to the nearest thousandth of a share of NUI Common Stock, equal to the
  number determined by dividing $71.50 by the arithmetic average of the daily
  closing price per share of NUI Common Stock (the "Average Market Price") as
  reported on the Composite Tape of the NYSE for the twenty trading days
  immediately prior to the Effective Time of the PSGS Merger; provided, however,
  that each share of PSGS Common Stock to be converted, shall be converted into
  no more than 3.0 and no less than 2.4 shares of NUI Common Stock, except that

                                        32
<PAGE>



  if NUI pays a stock dividend or effects a stock split or reverse stock split
  prior to the Effective Time of the PSGS Merger, such 3.0 and 2.4 shares of NUI
  Common Stock shall be adjusted to give effect to such event (the "Merger
  Consideration"). Market fluctuations in the price of NUI Common Stock will
  affect the conversion ratio applicable to the PSGS Common Stock. 

          Except as adjusted in the event of a NUI stock dividend, stock split
  or reverse stock split prior to the Effective Time of the PSGS Merger, each
  share of PSGS Common Stock to be converted shall be converted into 3.0 shares
  of NUI Common Stock if the Average Market Price is $23.833 per share or lower
  and shall be converted into 2.4 shares of NUI Common Stock if the Average
  Market Price is $29.792 per share or higher.

          THE AVERAGE MARKET PRICE MAY BE MORE OR LESS THAN THE ACTUAL MARKET
  PRICE OF NUI COMMON STOCK ON THE DAY OF THE PSGS STOCKHOLDERS MEETING, AT THE
  EFFECTIVE TIME OF THE PSGS MERGER OR ON THE DAY ON WHICH CERTIFICATES FOR
  SHARES OF NUI COMMON STOCK ARE SENT TO FORMER PSGS STOCKHOLDERS.

          Exchange Procedure. As promptly as practicable after the Effective
  Time of the PSGS Merger, a letter of transmittal (the "Transmittal Form") will
  be mailed to each person who is a holder of record of shares of PSGS Common
  Stock which are outstanding as of the Effective Time of the PSGS Merger. The
  Transmittal Form will specify the procedure for surrendering certificates
  representing shares of PSGS Common Stock to the bank or trust company
  designated on the Transmittal Form (the "Exchange Agent"). As soon as
  practicable following the surrender to the Exchange Agent of such
  certificates, the Exchange Agent will deliver certificates evidencing shares
  of NUI Common Stock in accordance with instructions set forth in the
  Transmittal Form. NUI has agreed to deposit with the Exchange Agent at the
  Effective Time of the PSGS Merger that number of shares of NUI Common Stock to
  be issued pursuant to the Merger Agreement for the purpose of exchange of, and
  payment for, shares of PSGS Common Stock.

          No fractional shares of NUI Common Stock will be issued in the PSGS
  Merger. Instead, any PSGS Stockholder otherwise entitled to receive a
  fractional share of NUI Common Stock will be paid an amount of cash, without
  interest, equal to such fraction multiplied by the Average Market Price.

          Until such shares of PSGS Common Stock are surrendered, each
  certificate of PSGS Common Stock (other than PSGS Cancelled Shares and PSGS
  Dissenting Shares) that immediately prior to the Effective Time of the PSGS
  Merger shall have represented any of the PSGS Common Stock shall be deemed at
  and after the Effective Time of the PSGS Merger to represent only the right to
  receive, upon such surrender, the Merger Consideration. The holder thereof,
  however, will not be entitled to receive any dividend or distribution payable
  to holders of NUI Common Stock, subject to applicable escheat laws until such
  certificate of PSGS Common Stock has been surrendered (or, if missing,
  otherwise documented) in accordance with the procedures set forth in the
  Transmittal Form. All such dividends or distributions will be accrued and
  paid, without interest, to the holder of record of the NUI Common Stock for
  which certificates are delivered upon such surrender, subject to applicable
  escheat laws.

          Beneficial owners of shares of PSGS Common Stock held of record by
  others should contact the record owners to provide appropriate instructions
  for completion of the Transmittal Form.

          Effective Time of the PSGS Merger. If the Merger Agreement is approved

                                        33
<PAGE>



  by the PSGS Stockholders, the PSGS Merger will be consummated as soon as
  practicable after the other conditions to the consummation of the PSGS Merger
  set forth in the Merger Agreement are satisfied or, to the extent permitted,
  waived. See "PSGS Merger-Basic Terms of Merger Agreement-Conditions to
  Consummation of the PSGS Merger." The Effective Time of the PSGS Merger will
  occur on the later of the filing of a certificate of merger with the Secretary
  of State of the State of New Jersey and the filing of a certificate of merger
  with the Secretary of State of the State of Delaware or at such other time, if
  any, set forth in such certificates of merger. 

          Certain Covenants. PSGS has agreed that during the period prior to the
  Effective Time of the PSGS Merger (except as expressly permitted by the Merger
  Agreement or to the extent that NUI shall otherwise consent in writing), PSGS
  and each of its subsidiaries will conduct its operations in the ordinary and
  usual course of business and consistent with past practice, and will use its
  best efforts to preserve intact its business organizations, keep available the
  services of its officers and employees and maintain satisfactory relationships
  with customers, suppliers, distributors and others having business
  relationships with it. In addition, PSGS has agreed that during the period
  prior to the Effective Time of the PSGS Merger, it will not and will cause
  each of its subsidiaries to not (except as expressly permitted by the Merger
  Agreement or to the extent that NUI shall otherwise consent in writing): (a)
  amend the PSGS Certificate of Incorporation, as amended (the "PSGS
  Certificate"), (or comparable charter documents) or the PSGS By-Laws, as
  amended (the "PSGS By-Laws"); (b) issue, sell, transfer, distribute, pledge or
  otherwise encumber or dispose of any shares of capital stock, any options,
  warrants or rights of any kind to acquire any shares of capital stock or any
  securities which are convertible into or exchangeable for any shares of such
  capital stock; (c) (i) split, combine, recapitalize or reclassify any shares
  of its capital stock; (ii) declare, set aside or pay any dividends on or make
  any other distributions (whether in cash, stock, or property or any
  combination thereof) in respect of any shares of its capital stock, or redeem
  or otherwise acquire any shares of capital stock or of any of its
  subsidiaries, except (1) any subsidiary of PSGS may declare and pay dividends
  to PSGS or any other subsidiary of PSGS and (2) PSGS may declare and pay
  regular quarterly dividends of not more than $0.44 per share on its customary
  quarterly dividend declaration and payment dates; (d) (i) except for certain
  budgeted annual salary increases, adopt, enter into or amend any bonus, profit
  sharing, compensation, stock option, warrant, pension, retirement, deferred
  compensation, employment, consulting, indemnification, severance, termination
  or other employee benefit plan, agreement, trust fund or arrangement for the
  benefit or welfare of any officer, director or employee or (ii) agree to any
  increase in the compensation (including bonuses) payable or to become payable
  to any officer, director or employee; (e) purchase or otherwise acquire, by
  merger, consolidation, acquisition of securities or assets or otherwise,
  (i) any corporation, partnership, association or other business entity,
  organization or division thereof or (ii) any assets or properties, which, in
  the case of either clause (i) or clause (ii), would be material, in the
  aggregate, to PSGS and its subsidiaries taken as a whole; (f) sell, lease,
  mortgage, pledge, grant a security interest in or a lien on, or otherwise
  dispose of or encumber any of its assets or properties which are material, in
  the aggregate, to PSGS and its subsidiaries taken as a whole; (g) settle or
  compromise any litigation or regulatory proceeding involving the payment or
  expenditure of, or an agreement, understanding or commitment to pay over time,
  an amount in cash, notes or other property, over any amount paid by insurance
  in excess of $10,000; (h) except for (i) short-term indebtedness incurred in
  the ordinary course of business consistent with past practices and (ii) bank
  line of credit borrowings that shall not exceed $12,500,000 at any time, incur

                                        34
<PAGE>



  any indebtedness for borrowed money or guarantee any such indebtedness or
  issue or sell any debt securities or guarantee any debt securities of others;
  (i) enter into any agreement, understanding or commitment which has a term of
  more than one year, unless such agreement, understanding or commitment may be
  terminated by PSGS and, after the Effective Time of the PSGS Merger, NUI at
  any time upon no more than thirty (30) days notice without any penalty or
  payment of any kind or (j) agree, whether in writing or otherwise, to do any
  of the foregoing. 

          PSGS has agreed that neither PSGS nor any affiliate of PSGS, nor any
  officer, director, employee, shareholder, representative or agent of PSGS or
  any affiliate of PSGS, shall, directly or indirectly, solicit or initiate or
  participate in any way in discussions or negotiations with, or provide any
  information or assistance to, or enter into an agreement or understanding with
  any person or group of persons (other than NUI) concerning any acquisition,
  merger, consolidation, liquidation, dissolution, disposition or other
  transaction that would result in the transfer to any such person or group of
  persons (other than in the ordinary course of business) of all or any
  substantial part of the business or assets of, or all or any substantial
  equity interest in, PSGS or any of its subsidiaries. PSGS has also agreed to
  provide prompt notice to NUI of any such discussions or negotiations.

          NUI has agreed that, without the prior written consent of PSGS, it
  will not declare, set aside or pay any cash dividend in respect of any shares
  of NUI Common Stock, except that NUI may declare and pay to holders of shares
  of NUI Common Stock regular quarterly dividends of not more than $0.50 per
  share on its customary quarterly dividend declaration and payment dates.

          NUI has agreed to take all required corporate action necessary and NUI
  and PSGS have agreed to use their respective best efforts to obtain all
  required consents and approvals so that on the day of the Effective Time of
  the PSGS Merger at or after the time of consummation of the PSGS Merger, the
  EGC Merger will be consummated.

          For information regarding the manner in which NUI is obligated after
  the Effective Time of the PSGS Merger to run the business formerly conducted
  by PSGS, see "PSGS Merger - Basic Terms of Merger Agreement-Operation of PSGS
  After the PSGS Merger."

          For information regarding the obligation of NUI to provide liability
  insurance to the directors and officers of PSGS, see "PSGS Merger-Basic Terms
  of Merger Agreement-Interest of PSGS Management and Directors."

          Representations and Warranties. PSGS and NUI have made a number of
  representations and warranties to one another. PSGS has made representations
  and warranties to NUI concerning, among other things, incorporation and
  qualification to do business of PSGS and its subsidiaries, capitalization of
  PSGS, corporate standing and authority of PSGS, consents, litigation,
  financial statements, material adverse effects, employee benefit plans,
  insurance, labor matters, tax returns and audits, compliance with applicable
  laws, environmental matters and undisclosed liabilities. NUI has made
  representations and warranties to PSGS concerning, among other things,
  incorporation and qualification to do business of NUI and its subsidiaries,
  capitalization of NUI, corporate standing and authority of NUI, litigation,
  tax returns and audits, labor matters and insurance. 

          Conditions to Consummation of the PSGS Merger. The respective
  obligations of each of NUI and PSGS to consummate the PSGS Merger are subject

                                        35

  to the satisfaction at or prior to the closing of the PSGS Merger (the
  "Closing") of certain conditions, any one or more of which may be waived in

  following: (a) the Merger Agreement shall have been duly adopted and approved
  by the requisite vote of the PSGS Stockholders in accordance with applicable
  law; (b) the waiting period (and any extension thereof) applicable to the
  consummation of the PSGS Merger under the Hart-Scott-Rodino Antitrust
  Improvements Act of 1976, as amended (the "HSR Act"), shall have expired or

  decree, order or injunction shall have been promulgated, enacted, entered or
  enforced by any United States federal, state or local government (including
  the District of Columbia), governmental or regulatory authority, governmental

  judicial authority ("Governmental Entities"), which restricts or prohibits the
  consummation of the PSGS Merger and, in any such case, remains in full force
  and effect on the date of the Closing (the "Closing Date"); (d) the
  Registration Statement shall have become effective and no stop order
  suspending the effectiveness of the Registration Statement shall have been
  issued and no proceedings for that purpose shall have been initiated or
  threatened by the SEC and (e) the NYSE shall have approved the listing, upon
  official notice of issuance, of the shares of NUI Common Stock to be issued
  upon consummation of the PSGS Merger.

          The obligation of NUI to consummate the PSGS Merger is also subject to
  the satisfaction of certain additional conditions, including the following,
  unless waived by NUI: (a) the representations and warranties of PSGS contained
  in the Merger Agreement shall be true in all material respects as of the date
  thereof and shall be true in all material respects as of the Closing (except
  for such changes therein permitted by the Merger Agreement), and the
  obligations of PSGS under the Merger Agreement required to be performed by
  PSGS at or prior to the Closing shall have been duly performed and complied
  with in all material respects; (b) (i) all permits, authorizations, consents
  and approvals of any Governmental Entity required to be obtained by PSGS, any
  of its subsidiaries, NUI or any of its subsidiaries as a condition to the
  lawful consummation of the transactions contemplated by the Merger Agreement
  shall have been obtained and (ii) all consents and approvals of each person
  whose consent or approval is required pursuant to any agreement or instrument
  prior to the consummation of the transactions contemplated by the Merger
  Agreement shall have been obtained, except with regard to the foregoing
  clauses (i) and (ii), such permits, authorizations, consents and approvals
  which in the aggregate, if not made or obtained, would not have a material
  adverse effect on the business, financial (or other) condition, results of
  operations or prospects ("Material Adverse Effect") of NUI or its
  subsidiaries, taken as a whole, or PSGS and its subsidiaries, taken as a
  whole; (c) holders of less than 5% of the shares of the PSGS Common Stock
  shall have exercised their right to dissent and seek appraisal of such shares
  pursuant to the DGCL and (d) no law, statute, ordinance, rule, regulation,

  Adverse Effect on PSGS and its subsidiaries, taken as a whole, or, upon
  consummation of the PSGS Merger and the EGC Merger, on NUI and its
  subsidiaries, taken as a whole, and, in any such case, remains in full force
  and effect on the Closing Date. 

          The obligation of PSGS to consummate the PSGS Merger is also subject
  to the satisfaction of certain additional conditions, including the following,
  unless waived by PSGS: (a) the representations and warranties of NUI contained
  in the Merger Agreement shall be true in all material respects as of the date

                                        36
<PAGE>



  thereof and shall be true in all material respects as of the Closing (except
  for such changes therein permitted by the Merger Agreement), and the
  obligations of NUI under the Merger Agreement required to be performed by it
  at or prior to the Closing shall have been duly performed and complied with in
  all material respects; (b) all permits, authorizations, consents and approvals
  of any Governmental Entity required to be obtained by PSGS, any of its
  subsidiaries, or NUI or any of its subsidiaries as a condition to the lawful
  consummation of the PSGS Merger which, in the aggregate if not obtained, would
  have a Material Adverse Effect on NUI and its subsidiaries, taken as a whole,
  shall have been obtained and (c) no law, statute, ordinance, rule, regulation,
  judgment, decree, order or injunction shall have been promulgated, enacted,
  entered or enforced by any Governmental Entity, which would have a Material
  Adverse Effect on NUI and its subsidiaries taken as a whole and, in any such
  case, remains in full force and effect on the Closing Date. 

          Regulatory Filings and Approvals. EGC is subject, as a public utility
  company, to the jurisdiction of the New Jersey Board of Regulatory
  Commissioners (the "NJBRC") and the Florida Public Service Commission (the
  "FPSC") with respect to service and facilities, rates and charges,
  classification of accounts, valuations of property, issuances of securities
  and various other matters.

          PSGS's natural gas operations are regulated by the Pennsylvania Public
  Utility Commission (the "PPUC"), the New York Public Service Commission (the
  "NYPSC"), the Maryland Public Service Commission (the "MPSC") and the North
  Carolina Utilities Commission (the "NCUC") with respect to service and
  facilities, rates and charges, classification of accounts, valuations of
  property and various other matters.

          After the PSGS Merger and the EGC Merger are consummated, NUI will be
  subject to the jurisdiction of the NJBRC and the FPSC with respect to the same
  matters as EGC is currently subject, and NUI will be subject to the
  jurisdiction of the PPUC, the NYPSC, the MPSC and the NCUC with respect to the
  same matters as PSGS is currently subject. 

          The PSGS Merger is subject to prior approval by the PPUC, the NYPSC,
  the MPSC and the NCUC and to this end a joint application of PSGS and NUI was
  filed with the PPUC on September 3, 1993; the MPSC on September 9, 1993 and
  the NCUC on September 10, 1993, seeking approval of: (a) the Merger Agreement;
  (b) the transfer to NUI of all of PSGS's rights to offer, render, furnish, or
  supply gas service; (c) the commencement of gas service by NUI and (d) the
  abandonment of gas service by PSGS. Such approval was obtained from the MPSC
  on September 9, 1993, the PPUC on November 10, 1993, and the NCUC on December
  15, 1993. On December 30, 1993, the public staff of the NCUC filed a notice of
  appeal and exceptions with respect to the NCUC's December 15, 1993 order and
  requested that the NCUC postpone the effective date of its order. On January
  6, 1994, the NCUC denied the public staff's request to postpone the effective
  date of the NCUC's December 15, 1993 order. A joint application of PSGS and
  NUI was filed with the NYPSC on September 14, 1993, seeking approval for NUI
  to acquire all of the outstanding stock and assume the debt obligations of
  PSGS.

          The EGC Merger is subject to prior approval by the NJBRC, and to this
  end a joint application of NUI and EGC was filed with the NJBRC on September
  13, 1993, seeking approval of: (a) the transfer of all of the assets of NUI's
  New Jersey Division from EGC to NUI; (b) the adoption by NUI of tariffs, the
  assumption by NUI of the securities and other debt obligations, the adoption
  by NUI of the depreciation rates, and the assignment to NUI of all contracts,

                                        37
<PAGE>



  of NUI's New Jersey Division presently applicable to EGC; (c) the transfer of
  all of the franchises of NUI's New Jersey Division from EGC to NUI, and the
  assumption by NUI of all service obligations of NUI's New Jersey Division
  presently applicable to EGC; (d) the maintenance of certain of NUI's books and
  records outside of the State of New Jersey and (e) the authority for NUI to
  continue to issue NUI Common Stock under certain currently effective stock
  distribution plans. NUI is unable to predict at this time the date or the
  outcome of the NJBRC's determination with respect to the application.

          The PSGS Merger is subject to the requirements of the HSR Act, and the
  rules and regulations thereunder, which provide that certain transactions may
  not be consummated until required information has been furnished to the
  Antitrust Division of the Department of Justice (the "Antitrust Division") and
  the Federal Trade Commission ("FTC") and certain waiting periods have been
  satisfied. NUI and PSGS filed the required information and material with the
  Antitrust Division and the FTC on November 9, 1993. The waiting period
  terminated on December 9, 1993. The termination of the waiting period does not
  preclude the Antitrust Division or the FTC from challenging the PSGS Merger on
  antitrust grounds.

          In addition, PSGS and NUI must receive the approval of the FERC in
  order to effect the PSGS Merger. To this end, a joint application of PSGS and
  NUI was filed with FERC on December 21, 1993.

          It is a condition to each of the parties' obligation to consummate the
  PSGS Merger that all necessary regulatory approvals be in full force and
  effect and not subject to any condition which would prevent consummation of
  the PSGS Merger. The parties have agreed to use their best efforts to obtain
  all necessary regulatory approvals. Either NUI or PSGS may unilaterally
  terminate the Merger Agreement if any Governmental Entity, the consent of
  which is a condition to the obligation of such party to consummate the PSGS
  Merger, has determined not to grant its consent and all appeals of such
  determination have been taken and have been unsuccessful. See "PSGS Merger-
  Basic Terms of Merger Agreement-Amendment and Termination."

          Other Consents and Approvals. Other governmental approvals and
  consents required to consummate the PSGS Merger include consents required in
  order to transfer PSGS's utility franchises and EGC's utility franchise to NUI
  and consents required under the New Jersey Industrial Site Recovery Act.

          Amendment and Termination. The Merger Agreement may not be amended
  except by an instrument in writing executed on behalf of NUI and PSGS,
  provided, however, that after the approval of the Merger Agreement by the PSGS
  Stockholders, no amendment may be made which would change (a) the amount or
  type of consideration to be received for or on conversion of all or any of the
  shares of the PSGS Common Stock upon consummation of the PSGS Merger, (b) any
  term of the Amended and Restated Certificate of Incorporation of NUI (the "NUI
  Certificate") or (c) any of the terms and conditions of the Merger Agreement
  if such change would adversely affect the PSGS Stockholders.

          The Merger Agreement may be terminated at any time prior to the
  Effective Time of the PSGS Merger, before or after approval of matters
  presented in connection with the PSGS Merger to the PSGS Stockholders: (a) by
  mutual consent of NUI and PSGS; (b) by either NUI or PSGS if: (i) a permanent
  injunction is entered, enforced or deemed applicable to the PSGS Merger which
  prohibits the consummation of the PSGS Merger and all appeals of such
  injunction shall have been taken and shall have been unsuccessful; (ii) at the
  PSGS Special Meeting (including any adjournment or postponement thereof) or

                                        38
<PAGE>



  any successor meeting called for the same purpose, the requisite affirmative
  approval of the PSGS Stockholders shall not have been obtained; (iii) any
  Governmental Entity, the consent of which is a condition to the obligations of
  NUI and PSGS to consummate the PSGS Merger shall have determined not to grant
  its consent and all appeals of such determination have been taken and have
  been unsuccessful or (iv) without fault of the terminating party, the PSGS
  Merger has not been consummated by May 2, 1994 or (c) by NUI if: (i) a
  permanent injunction is entered, enforced or deemed applicable to the EGC
  Merger which prohibits the consummation of the EGC Merger and all appeals of
  such injunctions shall have been taken and shall have been unsuccessful or
  (ii) any Governmental Entity, the consent of which is a condition to the
  obligations of NUI or EGC to consummate the EGC Merger, shall have determined
  not to grant its consent and all appeals of such determination have been taken
  and have been unsuccessful.

          Listing on New York Stock Exchange. The NYSE has authorized the
  listing of the shares of NUI Common Stock issuable in connection with the PSGS
  Merger upon official notification of issuance. It is a condition to each
  party's obligation to consummate the PSGS Merger that such shares be approved
  for listing on the NYSE subject to official notice of issuance. See "PSGS
  Merger-Basic Terms of Merger Agreement-Certain Covenants."

          Certain Fees, Expenses and Related Matters. PSGS has agreed that from
  the date of the Merger Agreement and prior to the termination thereof, if any
  person or group other than NUI shall have (a) commenced a tender offer for 30%
  or more of the outstanding shares of PSGS Common Stock, the acceptance of
  which has been recommended by the Board of Directors of PSGS, or (b) entered
  into an agreement, understanding for, or effected, a merger or other business
  combination with PSGS, the acquisition of 30% or more of the outstanding
  shares of PSGS Common Stock or the acquisition of all or any substantial part
  of the business or assets of PSGS, then, at NUI's request, PSGS shall (i) pay
  to NUI (immediately upon submission by NUI of an invoice therefor) the sum of
  $500,000 plus all of the actual expenses of NUI and its subsidiaries
  (including legal fees and expenses) incurred in connection with the
  negotiation, preparation, execution and delivery of the Letter of Intent,
  dated June 24, 1993, between NUI and PSGS, the negotiation, preparation,
  execution and delivery of the Merger Agreement and any other actions taken in
  connection with the transactions contemplated thereby and (ii) pay to NUI, not
  later than the consummation of such tender offer or the closing of such
  merger, business combination or any such acquisition, as the case may be, the
  sum of $500,000. 

          Except as set forth in the preceding paragraph, each of the parties to
  the Merger Agreement will pay its own expenses in connection with the Merger
  Agreement.

          Operation of PSGS After the PSGS Merger. For at least three years
  after the Effective Time of the PSGS Merger, NUI has agreed to maintain PSGS's
  independent identity as a Division of NUI with its own Division Board of
  Directors.

          NUI has agreed to maintain for at least five years after the Effective
  Time of the PSGS Merger, the PSGS Retirement Plan and Employee Savings Plan as
  in effect on the date of the Merger Agreement or provide benefits comparable
  in type and amount to participants in such Plans. In addition, for a period of
  at least five years following the Effective Time of the PSGS Merger, NUI has
  agreed to continue to provide to each officer and employee of PSGS and its
  subsidiaries, for so long as such officer or other employee is employed during

                                        39
<PAGE>



  such period by NUI, benefits which in the aggregate are at least comparable to
  those currently provided by PSGS and its subsidiaries. 

          NUI has agreed that, if it terminates without cause the employment of
  any PSGS employee (other than Lyle C. Motley, Jr., James W. Carl, James K.
  Turpin, Bernard L. Smith and Donna K. Scrivens (see "PSGS Merger-Interest of
  PSGS Management and Directors-Management and Employment Agreement")) during
  the first year following the Closing Date, NUI shall pay to such employee an
  amount equal to one week's salary (at the then current salary) for each year
  such employee was employed by NUI (including employment by PSGS prior to the
  Closing Date).

  Interests of PSGS Management and Directors

          In considering the recommendations of the Board of Directors of PSGS
  with respect to the Merger Agreement, PSGS Stockholders should be aware that
  certain members of PSGS's management and its Board of Directors have certain
  interests that are described below that may present them with actual or
  potential conflicts of interest in connection with the Merger Agreement. 

          Management and Employment Agreements. NUI has agreed to enter into, at
  or prior to the Effective Time of the PSGS Merger, an employment agreement
  with Lyle C. Motley, Jr., President and Chief Executive Officer of PSGS.
  Pursuant to such employment agreement, NUI shall agree to employ Mr. Motley
  for a period of three years, commencing on the Closing Date on the basis of
  Mr. Motley's title, duties and salary structure as of June 23, 1993. Such
  employment agreement shall provide that in the event that (a) Mr. Motley
  terminates his employment because NUI requests Mr. Motley to relocate or Mr.
  Motley's title or duties are downgraded from his title or duties on June 23,
  1993 or (b) NUI terminates Mr. Motley's employment without cause, NUI shall
  pay to Mr. Motley the salary payments payable to Mr. Motley under the terms of
  such employment agreement from the date of such termination through the
  remainder of such three-year period.

          NUI has also agreed to enter into, at or prior to the Effective Time
  of the PSGS Merger, employment agreements with (a) James W. Carl, Vice
  President of PSGS, (b) James K. Turpin, Vice President of PSGS, (c) Bernard L.
  Smith, Treasurer and Assistant Secretary of PSGS, and (d) Donna K. Scrivens,
  Secretary of PSGS (individually, an "Officer" and collectively, the
  "Officers"). Pursuant to such employment agreements, NUI shall agree to employ
  the Officers for a period of two years, commencing on the Closing Date on the
  basis of the Officers' respective titles, duties and salary structure as of
  June 23, 1993. Each such employment agreement shall provide that in the event
  NUI terminates the Officer's employment without cause, NUI shall pay to such
  Officer the salary payments payable to such Officer under the terms of such
  employment agreement from the date of such termination through the remainder
  of such two-year period. Each such employment agreement shall further provide
  that in the event that the Officer terminates his or her employment because
  NUI requests the Officer to relocate or the Officer's title or duties are
  downgraded from such Officer's title or duties on June 23, 1993, NUI shall pay
  to such Officer an amount equal to the greater of (a) the salary payments
  payable to such Officer under the terms of such employment agreement for a
  period of one year following the date of such termination and (b) one month's
  salary (at the then current salary) for each year such Officer was employed by
  NUI (including employment by PSGS prior to the Closing Date); provided,
  however, that in no event shall such payment exceed the salary payments
  payable to such Officer under the terms of such employment agreement from the
  date of such termination through the remainder of such two-year period.

                                        40
<PAGE>



          Insurance. After consummation of the PSGS Merger, the directors and
  officers of PSGS at the effective time of the PSGS merger will be insured
  under an extension of their current AEGIS Directors and Officers Liability
  policy.

          Stock Ownership. As of December 21, 1993, executive officers and
  directors of PSGS owned an aggregate 81,151 shares of PSGS Common Stock.

  Federal Income Tax Considerations

          PSGS Counsel has advised PSGS that for federal income tax purposes,
  under current law, assuming that the PSGS Merger and related transactions take
  place as described in the Merger Agreement, the PSGS Merger will constitute a
  reorganization within the meaning of Section 368(a) of the Code, and PSGS and
  NUI will each be a party to the reorganization within the meaning of Section
  368(b) of the Code.

          PSGS Counsel has advised that the following will be the material
  federal income tax consequences of the PSGS Merger:

          (i)  no gain or loss will be recognized by PSGS or NUI in the PSGS
  Merger;

          (ii) no gain or loss will be recognized by the stockholders of PSGS
  upon their receipt of NUI Common Stock in exchange for their PSGS Common
  Stock, except that stockholders who receive cash proceeds in lieu of
  fractional interests in NUI Common Stock will recognize gain or loss equal to
  the difference between such proceeds and the tax basis allocated to their
  fractional share interests, and such gain or loss will constitute capital gain
  or loss if their PSGS Common Stock is held as a capital asset at the Effective
  Date;

          (iii)     the tax basis of the shares of NUI Common Stock (including
  fractional share interests) received by the PSGS Stockholders will be the same
  as the tax basis of their PSGS Common Stock exchanged therefor; and

          (iv) the holding period of the NUI Common Stock in the hands of PSGS
  Stockholders will include the holding period of their PSGS Common Stock
  exchanged therefor, provided such PSGS Common Stock is held as a capital asset
  at the Effective Time of the PSGS Merger.

          No advance ruling from the Internal Revenue Service ("Service") with
  respect to the federal income tax consequences of the PSGS Merger is being
  sought. As a general matter, the Service no longer will rule on the federal
  income tax consequences of a proposed merger. The foregoing tax discussion is
  based upon opinions to be rendered by PSGS Counsel; however, such opinions are
  not binding on the Service. In rendering its advice, counsel will assume that
  the parties to the Merger Agreement will comply with various representations
  and covenants contained therein and that certain major stockholders of PSGS
  will comply with representations and covenants they have made in the
  Continuity of Interest Agreement, dated as of October 8, 1993, by and among
  NUI, PSGS and certain PSGS Stockholders (the "Continuity of Interest
  Agreement"). Among such representations and covenants are a covenant by such
  major stockholders to restrict for a stated period of time the disposition of
  a certain percentage of the NUI Common Stock they will receive pursuant to the
  PSGS Merger (see "Resale of NUI Common Stock"), a representation by such major
  stockholders that they have no present plan, intention or arrangement to
  dispose of any of the NUI Common Stock to be received in the PSGS Merger and a

                                        41
<PAGE>



  representation by NUI that it presently plans and intends either to (i)
  continue the historic business of PSGS after the PSGS Merger or (ii) use a
  significant portion of PSGS' historic business assets in a business. A breach
  of any of these representations or covenants could jeopardize the
  qualification of the PSGS Merger as a tax-free reorganization. If the PSGS
  Merger does not qualify as a tax-free reorganization, PSGS Stockholders who
  receive NUI Common Stock in the PSGS Merger will recognize capital gain or
  loss equal to the difference between (i) the fair market value of the NUI
  Common Stock received in the PSGS Merger and (ii) such holder's tax basis in
  his or her PSGS Common Stock. A PSGS Stockholder who receives solely cash in
  exchange for his or her PSGS Common Stock pursuant to the exercise of
  appraisal rights (see "Appraisal Rights"), generally will recognize capital
  gain or loss equal to the difference between (i) the amount of cash received
  and (ii) such holder's tax basis in his or her PSGS Common Stock.

          THE DISCUSSION SET FORTH ABOVE DOES NOT ADDRESS THE STATE, LOCAL OR
  FOREIGN TAX ASPECTS OF THE PSGS MERGER. THE DISCUSSION IS BASED ON CURRENTLY
  EXISTING PROVISIONS OF THE CODE, EXISTING AND PROPOSED TREASURY REGULATIONS
  THEREUNDER AND CURRENT ADMINISTRATIVE RULINGS AND COURT DECISIONS. ALL OF THE
  FOREGOING ARE SUBJECT TO CHANGE AND ANY SUCH CHANGE COULD AFFECT THE
  CONTINUING VALIDITY OF THIS DISCUSSION. EACH PSGS STOCKHOLDER SHOULD CONSULT
  HIS OR HER OWN TAX ADVISOR WITH RESPECT TO THE SPECIFIC TAX CONSEQUENCES OF
  THE PSGS MERGER TO HIM OR HER, INCLUDING THE APPLICATION AND EFFECT OF STATE,
  LOCAL AND FOREIGN TAX LAWS.

  Resale of NUI Common Stock

          Under applicable federal securities laws, the shares of NUI Common
  Stock issuable to the PSGS Stockholders in the PSGS Merger may be traded
  freely and without restriction by those PSGS Stockholders who are not deemed
  to be "affiliates" of either NUI or PSGS within the meaning of Rule 145
  promulgated under the Securities Act ("Rule 145"). Persons who may be deemed
  to be affiliates of PSGS generally include individuals or entities that
  control, or are controlled by, or are under common control with, PSGS and may
  include certain officers and directors of PSGS as well as principal PSGS
  Stockholders. Affiliates may resell shares of NUI Common Stock only in
  transactions permitted by Rule 145, pursuant to an effective registration
  statement under the Securities Act or in transactions otherwise exempt from
  registration. Prior to the PSGS Merger, PSGS will cause to be delivered to NUI
  a written agreement, from any person deemed an affiliate, to the effect that
  no disposition of NUI Common Stock received in the PSGS Merger will be made
  except as permitted by Rule 145 or in a transaction which is exempt under the
  Securities Act.

          As indicated above, the PSGS Merger is intended to qualify as a
  tax-free reorganization under Section 368(a) of the Code. One of the
  requirements for a tax-free reorganization is that the former shareholders of
  the acquired corporation maintain a continuity of proprietary interest in the
  acquiring corporation through ownership of the acquiring corporation's stock.
  There is no bright-line rule as to the percentage of stock consideration which
  must be received and retained by the historic shareholders of the acquired
  corporation in order to satisfy such a continuity of interest test. Likewise,
  there is no fixed period after a merger during which the historic shareholders
  of the acquired corporation must retain the acquiring corporation's stock. In
  connection with this requirement, upon advise of PSGS Counsel and NUI Counsel,
  certain Major Stockholders have agreed to restrict transfers of a portion of
  their PSGS Common Stock during a limited pre-Merger period and a portion of
  their NUI Common Stock during the one year period commencing with the

                                        42
<PAGE>



  Effective Time of the PSGS Merger, such that at least 40% in value of the
  total PSGS Common Stock held by all PSGS historic shareholders is retained by
  the Major Stockholders in the form of continued ownership of NUI Common Stock.
  In accordance with Internal Revenue Service guidelines, "Major Stockholders"
  for this purpose include (i) all shareholders who own beneficially 1% or more
  of PSGS's outstanding stock, (ii) all officers and directors of PSGS and (iii)
  certain relatives of, and entities controlled by or under common control with,
  the above-described shareholders. The Major Stockholders have executed the
  Continuity of Interest Agreement, which contains a formula designed to meet
  the 40% goal during the pre-Merger and one year post-Merger period by
  restricting sales of a specified percentage of each Major Stockholder's
  shares. The Major Stockholders, by executing the Continuity of Interest
  Agreement, also represent that they have no present plan, intention or
  arrangement to dispose of any of the NUI Common Stock to be received in the
  PSGS Merger.

          Execution of the Continuity of Interest Agreement by the required
  number of Major Stockholders is a condition to Closing under the Merger
  Agreement. As of the date of this Proxy Statement/Prospectus, holders of more
  than 68.54% of the outstanding shares of PSGS Common Stock have executed the
  Continuity of Interest Agreement so that this condition has been satisfied.

          The restrictions on transfers of PSGS Common Stock and NUI Common
  Stock during the pre-Merger and one year post-Merger period under the
  Continuity of Interest Agreement are in addition to the securities law
  restrictions on transfers described above.

  Accounting Treatment

          The PSGS Merger will be accounted for as a purchase of PSGS by NUI in
  accordance with generally accepted accounting principles. The regulatory
  process establishes rates on the basis of historical net book value;
  therefore, the underlying net assets of PSGS will, generally, be recorded as
  net assets of NUI at their historical net book value and the excess of the
  purchase price over the recorded net assets of PSGS, which amounts to
  approximately $6.8 million, will be added to utility plant as a "utility plant
  acquisition adjustment," which will be amortized over a thirty-year period
  that approximates the remaining useful life of the utility plant acquired. See
  "Pro Forma NUI Financial Data."

  Comparison of PSGS Stockholder Rights with NUI Shareholder Rights

          Upon consummation of the PSGS Merger, PSGS Stockholders will receive
  NUI Common Stock and will become shareholders of NUI. Consequently, such
  stockholders' rights will be governed by the corporation law of New Jersey,
  the state of NUI's incorporation, by the NUI Certificate and by the NUI
  Amended and Restated By-Laws, (the "NUI By-Laws"), which differ in certain
  respects from the corporation law of Delaware, the state of PSGS's
  incorporation, the PSGS Certificate and the PSGS By-Laws. The following is a
  summary discussion of the most significant differences in shareholder rights.
  This summary is not intended to be complete and is qualified in its entirety
  by reference to the DGCL and the New Jersey Business Corporation Act (the
  "NJBCA") and to the respective corporate documents of NUI and PSGS.

          Voting Power. Depending upon the number of shares of NUI Common Stock
  issued upon the conversion of the PSGS Common Stock based upon the Average
  Market Price (see "PSGS Merger-Basic Terms of Merger Agreement-Conversion of
  PSGS Common Stock"), PSGS Stockholders, who formerly controlled 100% of the

                                        43
<PAGE>



  voting stock of PSGS, as a result of the issuance of shares of NUI Common
  Stock pursuant to the PSGS Merger, will own between approximately 7% and 8% of
  the shares of NUI Common Stock outstanding after the Effective Time of the
  PSGS Merger, thereby significantly reducing their voting power as a class in
  the surviving corporation, NUI. See "PSGS Merger-Basic Terms of Merger
  Agreement-Conversion of PSGS Common Stock."

          Preferred Stock Capitalization. PSGS is not authorized to issue
  preferred stock. The NUI Certificate authorizes the Board of Directors of NUI,
  without shareholder approval, to issue up to 5,000,000 shares of NUI preferred
  stock ("NUI Preferred Stock") in classes and series and to determine the
  designation, number of shares, relative voting rights, dividends, preferences,
  conversion, redemption and other rights of each such class or series, and to
  increase the number of shares of any such class or series up to the limit of
  the total authorized NUI Preferred Stock. The power to establish the rights
  and preferences of holders of any NUI Preferred Stock and issue such shares,
  however, may in the future affect the rights of PSGS Stockholders as NUI
  shareholders.

          Amendments of Governing Documents. In general, unless a corporation's
  certificate of incorporation requires a greater vote, the DGCL requires the
  affirmative vote of a majority of shares entitled to vote thereon, as well as
  a majority of the outstanding shares of any class entitled to vote as a class,
  to authorize amendments to a corporation's certificate of incorporation. The
  PSGS Certificate does not change the vote required under the DGCL.

          The NJBCA requires the affirmative vote of a majority of the votes
  cast by the holders entitled to vote thereon as well as, if any class or
  series is entitled to vote thereon as a class, the affirmative vote of a
  majority of the votes cast in each class vote to authorize amendments to a
  corporation's certificate of incorporation unless greater requirements are
  provided for by other provisions of the NJBCA for specific amendments or
  provided for in the corporation's certificate of incorporation. The NUI
  Certificate contains a provision requiring the approval of 75% of all of the
  then-outstanding shares of the voting stock, voting together as a single
  class, to amend certain provisions of the NUI Certificate. The provisions of
  the NUI Certificate which require a 75% vote for amendment are (i) the
  capitalization and the rights and privileges of each class of stock of NUI,
  (ii) the number of directors, classification of the Board of Directors into
  three classes and specific methods for appointment and removal of directors,
  (iii) the requirement that all shareholder actions (other than by unanimous
  written consent) be taken at a meeting, (iv) restrictions upon the calling of
  special meetings of shareholders to a majority of the Board of Directors of
  NUI, (v) limitation of the liability of NUI directors and officers for money
  damages for breach of fiduciary duty and indemnification of certain NUI
  directors, officers and agents under certain circumstances and (vi) procedures
  and requirements for amendment of the NUI Certificate. For a discussion
  regarding certain anti-takeover effects of a 75% voting requirement, see "PSGS
  Merger-Comparison of PSGS Stockholder Rights with NUI Shareholder Rights-
  Certain Anti-Takeover Matters-Classification of the Board of Directors of NUI"
  and "-Removal of Directors."

          Appraisal Rights. The DGCL provides that stockholders of a Delaware
  corporation generally have the right to dissent from, and to obtain payment of
  the fair value of shares in the event of, specified corporate actions
  including a merger or consolidation, and, if the certificate of incorporation
  provides, for amendments to the certificate of incorporation and a sale of all
  or substantially all of the assets of a corporation. No such appraisal rights

                                        44
<PAGE>



  exist for any such corporate action, however, with respect to securities
  (a) listed on a national securities exchange or designated as a national
  market system security on an inter-dealer quotation system by the National
  Association of Securities Dealers, Inc. or (b) held of record by more than
  2,000 stockholders, except if the securities converted by such corporate
  action are not converted solely into some combination of (i) shares of the
  surviving or resulting corporation, (ii) shares of any other corporation
  (which other corporation meets the requirements set forth in (a) or (b) above)
  or (iii) cash in lieu of fractional share of the corporations described in (i)
  or (ii) above. See "Appraisal Rights."

          The NJBCA grants dissenters' rights under certain circumstances,
  including in the case of a merger, a sale or disposition of all or
  substantially all of a corporation's assets; except that there are no
  dissenters' rights where the shares are, as is the case with the NUI Common
  Stock (both before and after the Mergers), listed on a national securities
  exchange or held of record by not less than 1,000 shareholders, or where the
  shareholder will receive consideration in the form of cash, securities listed
  on a national securities exchange or held of record by not less than 1,000
  holders, or a combination of cash and such securities.

          Special Meetings. Pursuant to the DGCL, special stockholder meetings
  may be called by the board of directors and by such person or persons as may
  be provided in the certificate of incorporation or the by-laws. The PSGS
  By-Laws provide that special meetings of the PSGS Stockholders may be called
  by the president, by the president or secretary upon the written request of a
  majority of the directors or at the written request of stockholders owning a
  majority in amount of the issued and outstanding capital stock of PSGS. Under
  the NJBCA, special meetings of shareholders may be called by the president or
  the board of directors, or by such other officers, directors or shareholders
  as may be provided in the by-laws, or upon application to a court by the
  holders of not less than 10% of the shares entitled to vote. The NUI
  Certificate provides that shareholder action may be taken only at an annual or
  special meeting of shareholders, prohibits shareholder action by written
  consent in lieu of a meeting (except for unanimous written consent of
  shareholders) and further provides that special meetings of shareholders may
  be called only pursuant to the written request of a majority of the entire
  board of directors or, as required by New Jersey law, by holders of not less
  than 10% of all the shares entitled to vote at a meeting upon application to a
  court, subject to the provisions of any NUI Preferred Stock.

          Shareholder Action by Written Consent. Under the DGCL, action by
  stockholders may be taken by the written consent of stockholders having not
  less than the minimum number of votes that would be necessary to authorize the
  action at a meeting. Under the NJBCA, except as provided in a corporation's
  certificate of incorporation or by-laws, action may be taken by the written
  consent of all of the shareholders entitled to vote thereon, except in the
  case of mergers, consolidations, sale of all or substantially all assets or
  similar transactions (which require all shareholders to consent in writing
  thereto or all of the shareholders entitled to vote thereon to consent in
  writing and the corporation to give certain advance notification to all other
  shareholders). The NUI Certificate requires the written consent of all of the
  shareholders to take any action in lieu of a meeting. 

          Removal of Directors. Pursuant to the DGCL, any director or the entire
  board of directors may be removed with or without cause by the majority vote
  of stockholders entitled to vote at an election of directors. The DGCL
  contains additional restrictions on the removal of a director of a corporation

                                        45
<PAGE>



  that has a classified board of directors or has cumulative voting; however,
  PSGS does not have a classified board of directors or cumulative voting.

          The NJBCA permits removal of directors for cause by a majority of
  shareholders entitled to vote for the election of directors and, unless
  otherwise provided in the corporation's certificate of incorporation, also
  permits removal of directors without cause by a like vote of the shareholders.
  However, shareholders of a corporation with a classified board of directors,
  as is the case with NUI, may only remove directors for cause. The NUI
  Certificate provides that any director, or the entire board of directors, may
  be removed from office at any time, but only for cause and only by the
  affirmative vote of the holders of at least 75% of all of the then-outstanding
  shares of the voting stock, voting together as a single class. If a director
  is to be removed, NUI must notify the director of the grounds for the proposed
  removal and the director shall have an opportunity, at the expense of NUI, to
  present a defense to the NUI Shareholders by a statement which accompanies or
  precedes NUI's solicitation of proxies to remove such director. For a
  discussion regarding certain anti-takeover effects of a 75% voting requirement
  for the removal of a director, see "PSGS Merger-Comparison of PSGS Stockholder
  Rights with NUI Shareholder Rights-Certain Anti-Takeover Matters."

          Vacancies on the Board of Directors. Under the DGCL, any vacancy
  occurring in any office of a Delaware corporation by death, resignation,
  removal or otherwise, shall be filled as the by-laws provide. The PSGS By-Laws
  provide that vacancies occurring in the office of any director or directors,
  from whatever cause arising, shall be filled by a majority of the remaining
  directors, although less than a quorum. Each person so selected shall serve
  for the balance of the unexpired term or until the next election of directors.
  Under the NJBCA, unless otherwise provided in the certificate of incorporation
  or in the by-laws, vacancies in the board of directors of a New Jersey
  corporation, including vacancies resulting from an increase in the number of
  directors or resulting from resignations may be filled by an affirmative vote
  of a majority of the remaining directors even though less than a quorum, or by
  a sole remaining director. A director so elected by the board shall hold
  office until the next succeeding annual meeting of shareholders and until his
  successor shall have been elected and qualified. Any directorship not filled
  by the board may be filled by the shareholders at an annual meeting or at a
  special meeting of shareholders called for that purpose. Subject to the rights
  of holders of any classes or series of NUI Preferred Stock, the NUI
  Certificate provides that vacancies resulting from an increase in the
  authorized number of directors or resulting from death, resignation,
  retirement, disqualification, removal or other cause may be filled only by a
  majority of the directors then in office, though less than a quorum. The NUI
  Certificate also provides that if under the NJBCA the NUI shareholders have
  the power to elect a director to fill such a vacancy at a special meeting of
  shareholders (which is the case under the NJBCA if the vacancy has not been
  filled by the directors), such a vacancy may be filled at such a meeting only
  by the affirmative vote of at least 75% of the then-outstanding shares of the
  voting stock, voting together as a single class. For a discussion regarding
  certain anti-takeover effects of a 75% voting requirement for filling
  vacancies of the board of directors, see "PSGS Merger-Comparison of PSGS
  Stockholder Rights with NUI Shareholder Rights-Certain Anti-Takeover Matters."

          Classified Board of Directors. Under the NJBCA, a New Jersey
  corporation may provide in its certificate of incorporation for the
  classification of its directors with respect to the time for which they shall
  severally hold office, but no class of directors shall hold office for a term
  shorter than one year or longer than five years and the term of office of at

                                        46
<PAGE>



  least one class of directors must expire in each year. In addition, any New
  Jersey corporation having more than one class or series of shares may provide
  in its certificate of incorporation for the election of one or more directors
  by the shareholders of any class or series to the exclusion of other
  shareholders. Also, the certificate of incorporation may grant shareholders of
  a class or series of shares the right to elect one or more directors upon the
  occurrence of stated events for a specified term or for a term ending upon the
  occurrence of stated events. As permitted under the NJBCA, the NUI Certificate
  provides that NUI's directors (other than those who may be elected by the
  holders of any class or series of preferred stock having a preference over the
  NUI Common Stock as to dividends or upon liquidation) are classified, with
  respect to the time for which they severally hold office, into three classes,
  as nearly equal as possible. Directors from each class are elected every three
  years to serve for a term of three years. Although permitted under the DGCL,
  PSGS does not have a classified board of directors. For a discussion regarding
  certain anti-takeover effects of a classified board of directors, see "PSGS
  Merger-Comparison of PSGS Stockholder Rights with NUI Shareholder Rights-
  Certain Anti-Takeover Matters."

          Limitations on Director Liability. The DGCL permits corporations to
  eliminate or limit the personal liability of a director to the corporation or
  its stockholders for monetary damages for breach of fiduciary duty as a
  director, provided that such provision can not eliminate or limit the
  liability or a director (a) for any breach of the director's duty of loyalty
  to the corporation or its stockholders, (b) for acts or omissions not in good
  faith or which involve intentional misconduct or a knowing violation of law,
  (c) for unlawful payment of dividends or stock repurchases or redemptions or
  (d) for any transaction from which the director derived an improper personal
  benefit. The PSGS Certificate contains a provision which limits the personal
  liability of directors and officers of PSGS to the fullest extent permissible
  under the DGCL. The NJBCA provides that the certificate of incorporation of a
  New Jersey corporation may contain a provision limiting director and officer
  liability. The NUI Certificate contains a provision limiting liability for
  directors and officers for monetary damages for breach of fiduciary duty,
  subject only to current restrictions on such limitations under the NJBCA.
  Currently, the NJBCA restricts such limitations if such breach of duty is
  based upon an act or omission (a) in breach of such person's duty of loyalty
  to the corporation or its shareholders, (b) not in good faith or involving a
  knowing violation of law or (c) resulting in receipt by such person of an
  improper personal benefit.

          Indemnification of Directors, Officers and Agents. Both the DGCL and
  the NJBCA permit a corporation under certain circumstances to indemnify a
  director, officer, employee or agent ("corporate agent") against his or her
  expenses and liabilities in connection with any proceeding involving such
  corporate agent by reason of his or her having been such a corporate agent.
  Both the DGCL and the NJBCA require that a corporate agent who has been
  successful on the merits or otherwise be indemnified by the corporation. The
  DGCL permits the payment of expenses in advance so long as the corporate agent
  undertakes to repay such expenses if such agent is ultimately found not to be
  entitled to indemnification. The PSGS By-Laws provide for indemnification to
  directors and officers against reasonable expenses and any liabilities paid or
  incurred in connection with any proceeding in which such directors and
  officers may be involved by reason of being or having been a director or
  officer of PSGS or by reason of the fact that such director or officer is or
  was serving at the request of PSGS as a corporate agent of any other entity.
  The NUI Certificate provides for indemnification of directors and officers of
  NUI and of people acting as corporate agents for another entity at the request

                                        47
<PAGE>



  of NUI to the fullest extent permitted under applicable New Jersey law, which,
  with certain limitations, permits corporations to indemnify a corporate agent
  against expenses and liabilities in connection with any proceeding involving
  the corporate agent by reason of his or her being or having been a corporate
  agent, other than a proceeding by or in the right of the corporation where the
  person or persons seeking indemnification has been adjudged to be liable to
  the corporation unless the applicable court deems indemnification proper in
  such a case. The NJBCA also permits the payment of expenses in advance so long
  as the corporate agent undertakes to repay such expenses if such corporate
  agent is ultimately found not to be entitled to indemnification. The NUI
  Certificate restricts indemnification for proceedings initiated by a person
  seeking indemnification unless the proceeding was authorized by the Board of
  Directors of NUI.

          Inspection of Books and Records. The DGCL provides an absolute right
  of inspection by a stockholder of the stockholders list and the corporation's
  books and records to any stockholder for any proper purpose (a purpose
  reasonably related to the interest of the person as a stockholder). The NJBCA
  provides for a right of inspection by a shareholder of the shareholders list
  and the corporation's minutes of shareholders' meetings by any person who has
  been a shareholder of record for at least six months or any person holding, or
  authorized in writing by the holders of, at least 5% of the outstanding shares
  of any class or series.

          Certain Business Combinations.

          Combinations Involving an Interested Shareholder. The DGCL prevents an
  "interested stockholder" (defined in general as a person owning 15% or more of
  a corporation's outstanding voting stock) from engaging in certain business
  combinations with a "publicly-held" Delaware corporation (one which is either
  (a) listed on a national securities exchange, (b) authorized for quotation on
  inter-dealer quotation system of a registered national securities association
  or (c) held of record by more than 2,000 stockholders) for three years
  following the date such person became an interested stockholder unless
  (i) before such person became an interested stockholder, the board of
  directors of the corporation approved either the business combination or the
  transaction in which the interested stockholder became an interested
  stockholder, (ii) upon consummation of the transaction that resulted in the
  interested stockholder's becoming an interested stockholder, the interested
  stockholder owns at least 85% of the voting stock of the corporation
  outstanding at the time the transaction commenced (excluding stock held by
  directors who are also officers of the corporation and by employee stock plans
  that do not provide employees with the rights to determine confidentially
  whether shares held subject to the plan will be tendered in a tender or
  exchange offer) or (iii) following the transaction in which such person became
  an interested stockholder, the business combination is approved by the board
  of directors of the corporation and authorized at a meeting of stockholders by
  the affirmative vote of the holders of 66-2/3% of the outstanding voting stock
  of the corporation not owned by the interested stockholder.

          The NJBCA imposes additional voting rights in the case of a business
  combination that involves any "interested stockholder." The NJBCA contains a
  statute entitled "New Jersey Shareholders Protection Act" that provides, among
  other things, that in addition to any requirements contained in the
  certificate of incorporation or by-laws of a resident domestic corporation, no
  such corporation may engage in any business combination with any "interested
  stockholder" of such corporation (defined as a beneficial owner of 10% or more
  of such corporation's stock) for a period of five years following the date of

                                        48
<PAGE>



  acquisition of stock such that such holder becomes an "interested stockholder"
  unless such combination is approved by the board of directors prior to such
  acquisition date. In addition to the foregoing, no New Jersey corporation may
  engage in a business combination with an interested stockholder other than one
  in which (a) the board of directors has approved such business combination
  prior to such interested stockholder's stock acquisition date, (b) such
  business combination is approved by the affirmative vote of the holders of
  two-thirds of the voting stock not beneficially owned by that interested
  stockholder at a meeting called for such purpose or (c) the aggregate amount
  of cash and the market value, as of the consummation date, of consideration to
  be received per share by holders of the outstanding shares of common stock in
  the business combination is at least equal to a certain "fair price" as
  determined by various criteria set forth in the statute, subject to certain
  exceptions.

          Other Business Combinations. Under the DGCL, any business combination
  or major asset sale transaction involving a Delaware corporation but not an
  "interested stockholder" would generally require the affirmative vote of a
  majority of the outstanding shares entitled to vote thereon. The PSGS
  Certificate restates the majority stockholder approval requirement for the
  sale, lease or exchange of all of the property and assets of PSGS. Under the
  NJBCA, which is not modified by the NUI Certificate, any business combination
  or major asset sale transaction between NUI and any person that is not an
  "interested stockholder" would generally require the affirmative vote of a
  majority of the votes cast by the holders of NUI Common Stock voting in person
  or by proxy. 

          Certain Anti-Takeover Matters.

          Effect of Classification of the Board of Directors of NUI. The
  classification of the Board of Directors of NUI pursuant to the NUI
  Certificate would delay NUI shareholders from removing a majority of the Board
  of Directors of NUI for two years, unless removal for cause can be established
  and the required 75% vote for removal can be obtained. Because the existence
  of a classified board would operate to delay a potential purchaser's ability
  to obtain control of the board in a relatively short period of time, a
  classified board may have the effect of discouraging attempts to acquire
  significant minority positions with the intent of obtaining control of NUI by
  electing a slate of directors. The delay arises because under this provision
  it could take a purchaser as long as two annual meetings of shareholders to
  elect a majority of the Board of Directors of NUI. Also because neither the
  NJBCA nor the NUI Certificate require cumulative voting, a purchaser of a
  block of stock of NUI constituting less than a majority of the outstanding
  shares has no assurance of proportional representation on the Board of
  Directors of NUI. For the same reasons, the classified board provision of the
  NUI Certificate may also deter certain mergers, tender offers or other future
  takeover attempts which some or a majority of the holders of NUI stock may
  deem to be in their best interests.

          Removal of Directors. The NUI Certificate also provides that directors
  may be removed only for cause and only by the affirmative vote of holders of
  at least 75% of the voting stock, voting together as a single class, that
  shareholder action can be taken only at an annual or special meeting of
  shareholders and prohibits shareholder action in lieu of a meeting unless such
  action is by unanimous written consent. The NUI Certificate and NUI By-Laws
  provide that, subject to the rights of any holders of any series of NUI
  Preferred Stock, special meetings of shareholders can only be called pursuant
  to a resolution adopted by a majority of the authorized directors of NUI and

                                        49
<PAGE>



  by a court upon the application to a court by the holders of not less than 10%
  of the shares entitled to vote. The NUI Certificate and the NUI By-Laws
  contain provisions requiring the affirmative vote of the holders of at least
  75% of the voting stock to amend certain provisions relating to the number,
  term, removal and classification of directors.

          These provisions taken together could impede the completion of a
  merger, tender offer or other takeover attempt by restricting the ability of
  any person, including a potential acquiror, of gaining control of the NUI
  Board of Directors. This could discourage an acquisition attempt or other
  transaction that some or a majority of the NUI shareholders might believe to
  be in their best interests or in which the NUI shareholders might receive a
  premium for their stock over the then market prices of such stock. NUI
  believes that its Board of Directors will make any determination with respect
  to the recommendation of an offer for the stock of the company based on its
  judgment as to the best interests of NUI and its then existing shareholders
  and that the requirement that directors may only be removed for cause together
  with the 75% affirmative voting requirement, a 75% voting requirement for any
  changes to the NUI Certificate and any shareholder amendment to the NUI
  By-Laws will enable the NUI Board of Directors to attain those best interests
  without an acquiror gaining control at a less than optimum price for NUI
  Common Stock.

          Issuance of Preferred Stock. As described above, the NUI Board of
  Directors is authorized to provide for the issuance of shares of NUI Preferred
  Stock, in one or more series, and to fix by resolution of the Board of
  Directors and to the extent permitted by New Jersey law, the terms and
  conditions of each such series. NUI believes that the availability of the NUI
  Preferred Stock provides NUI with increased flexibility in structuring
  possible future financings and acquisitions and in meeting other corporate
  needs which might arise. The authorized shares of NUI Preferred Stock, as well
  as shares of NUI Common Stock, are available for issuance without further
  action by the shareholders, unless such action is required by applicable law
  or the rules of any stock exchange on which shares of NUI Common Stock are
  listed or on which NUI Preferred Stock may be listed in the future.

          Although the NUI Board of Directors has no present intention of doing
  so, it could issue a series of NUI Preferred Stock that could, depending on
  the terms of such term series, impede the completion of a merger, tender offer
  or other takeover attempt by including class voting rights that would enable
  the holders of such series to block such a transaction. The Board of Directors
  of NUI will make any determination to issue such shares based on its judgment
  as to the best interests of NUI and its then existing shareholders. The Board
  of Directors of NUI, if so acting, could issue NUI Preferred Stock having
  terms that would discourage an acquisition attempt or other transaction that
  some or a majority of the shareholders might believe to be in their best
  interests or in which the shareholders might receive a premium for their stock
  over the then market price of such stock.

                                    EGC MERGER

  General

          Under the provisions of the PUHCA, in order to consummate the PSGS
  Merger, NUI will be required to eliminate its status as a public utility
  holding company by effecting the EGC Merger. The Board of Directors of NUI has
  prepared and approved the EGC Plan of Merger and Liquidation pursuant to
  which, at or after the Effective Time of the PSGS Merger, EGC will be merged

                                        50
<PAGE>



  with and into NUI pursuant to the NJBCA. No vote of the shareholders of either
  NUI or EGC is required in connection with the EGC Merger. The EGC Merger will
  be effective upon the filing of a certificate of merger with the Secretary of
  State of the State of New Jersey (the "Effective Time of the EGC Merger"). NUI
  will be the surviving corporation in the EGC Merger. At the Effective Time of
  the EGC Merger, all of the outstanding shares of EGC Common Stock will be
  cancelled. The operations of EGC will be continued by the New Jersey and
  Florida Divisions of NUI.

          For information regarding the regulatory filings and approvals
  relating to the EGC Merger, see "PSGS Merger-Basic Terms of Merger Agreement-
  Regulatory Filings and Approvals."

                                 APPRAISAL RIGHTS

          Pursuant to the DGCL, PSGS Stockholders have the right to dissent from
  the Merger, and to obtain an appraisal and payment of the "fair value" (as
  defined therein) of their PSGS Common Stock if the PSGS Merger is completed.

          Any PSGS Stockholder who contemplates exercising appraisal rights is
  urged to read carefully the provisions of Section 262 of the DGCL. The
  following summary of the steps to be taken in order to exercise appraisal
  rights is qualified in its entirety by the full text of Section 262 of the
  DGCL, which is attached as Annex C to this Proxy Statement/Prospectus.

          Each step must be taken in the indicated order and in strict
  compliance with the applicable provisions of the statute in order to perfect
  appraisal rights. The failure of any PSGS Stockholder to comply with the
  aforesaid steps will result in the PSGS Stockholder receiving the
  consideration contemplated by the Merger Agreement. See "PSGS Merger-Basic
  Terms of Merger Agreement-Conversion of PSGS Common Stock." Any written notice
  or demand which is required in connection with the exercise of appraisal
  rights, whether before or after the Effective Date, must be sent to PSGS, at
  102 Desmond Street, Sayre, Pennsylvania 18840, Attention: Secretary.

  Eligibility

          Any PSGS Stockholder who holds shares of PSGS Common Stock at the time
  he or she makes a demand to exercise appraisal rights, who continuously holds
  such shares through the Effective Date, who neither votes in favor of the
  Merger nor consents in writing thereto and who properly perfects his or her
  appraisal rights shall be entitled to an appraisal of the fair value of his or
  her shares. Failure by a PSGS Stockholder to vote against the PSGS Merger does
  not constitute a waiver of appraisal rights. Shares represented by proxies
  which do not contain voting instructions will be voted in favor of approval
  and adoption of the Merger Agreement and such shares will not be entitled to
  appraisal rights.

  Notice of Appraisal Rights

          Not less than twenty days prior to the PSGS Special Meeting, PSGS must
  notify PSGS Stockholders who are such as of the record date for the PSGS
  Special Meeting that appraisal rights are available for any or all such
  shares. This notice must include a copy of Section 262 of the DGCL. 

  Stockholder's Written Demand for Appraisal

          Any PSGS Stockholder who elects to dissent and to demand appraisal of

                                        51
<PAGE>



  his or her shares must deliver to PSGS, prior to the PSGS Stockholders' vote
  on the PSGS Merger at the PSGS Special Meeting, a separate written demand for
  appraisal of his or her shares. Such written demand for appraisal must
  reasonably inform PSGS of the PSGS Stockholder's identity and that he or she
  intends to demand an appraisal. Neither a proxy nor a vote against the PSGS
  Merger will constitute the necessary written demand for appraisal. 

  NUI's Response

          Within ten days of the Effective Time of the PSGS Merger, each PSGS
  Stockholder who delivered the above written demand for appraisal and who
  neither voted in favor of nor consented to the PSGS Merger shall receive from
  NUI notification of the date that the PSGS Merger has become effective.

  Stockholders' Rights After Demanding Appraisal

          Any PSGS Stockholder has the right to withdraw his or her written
  demand for appraisal and to accept the PSGS Merger terms at any time within
  sixty days after the Effective Time of the PSGS Merger. Within 120 days after
  the Effective Date, any PSGS Stockholder who has complied with the above
  requirements, upon written request, shall be entitled to receive from NUI a
  statement of the aggregate number of shares not voted in favor of the PSGS
  Merger and with respect to which written demands for appraisal were delivered
  and the aggregate number of holders of such shares. NUI must mail this
  statement within ten days after it receives a PSGS Stockholder's written
  request for such a statement, or within ten days after expiration of the
  period for delivery of written demands for appraisal, whichever is later. 

          From and after the Effective Time of the PSGS Merger, no PSGS
  Stockholder who has delivered his or her written demand for appraisal shall be
  entitled to vote his or her PSGS Common Stock for any purpose or to receive
  dividends or other distributions on the stock, except those payable to PSGS
  Stockholders of record at a date which is prior to the Effective Time of the
  PSGS Merger. 

  Petition for Appraisal

          Within 120 days after the Effective Time of the PSGS Merger, NUI or
  any PSGS Stockholder who has complied with the above requirements and is
  otherwise entitled to appraisal rights may file a petition in the Court of
  Chancery demanding a determination of share value. 

          If a PSGS Stockholder files a petition with the Court of Chancery,
  service of a copy of such petition must be made upon NUI. NUI must then,
  within twenty days after such service, file with the Register in Chancery a
  duly verified list containing the names and addresses of all of the PSGS
  Stockholders who have delivered written demands for appraisal but with whom
  NUI has not reached agreement as to the value of their shares. If NUI files a
  petition with the Court of Chancery, such a duly verified list must accompany
  its petition. 

  Notice of Hearing

          If the Court so orders, the Register in Chancery shall give approved
  forms of notice by mail and by publication of the time and place fixed for the
  hearing of such petition to NUI and to PSGS Stockholders shown on the duly
  verified list. NUI shall bear the costs of such notice.


                                        52

  Hearing

          The Court shall determine which PSGS Stockholders have complied with
  all provisions of the applicable law and have become entitled to appraisal
  rights. It may also require that such PSGS Stockholders submit their stock
  certificates to the Register in Chancery for notation thereon of the pendency
  of the appraisal proceeding. If the Court so requires and any such PSGS
  Stockholder fails to comply, the court may choose to dismiss the proceedings
  as to such PSGS stockholder.

          The Court shall appraise the shares and determine their fair value.
  Fair value shall exclude any element of value arising from the accomplishment
  or expectation of the Mergers but includes any fair rate of interest to be
  paid upon the amount determined to be fair value. The Court may take into
  account all relevant factors in determining fair value. Likewise, the
  determination of the fair rate of interest may be based on consideration of
  all relevant factors, including the rate of interest NUI would have to pay if
  it borrowed money during the course of the appraisal proceeding. Interest may
  be simple or compound.

          Upon application by NUI or by a PSGS Stockholder entitled to
  participate in the appraisal proceeding, the Court may exercise its discretion
  to permit discovery or other pretrial proceedings and to proceed to trial upon
  the appraisal prior to finally determining which PSGS Stockholders are
  entitled to an appraisal. Notwithstanding this discretion, any PSGS
  Stockholder whose name appears on NUI's duly verified list and who submitted
  his or her certificates, if so required, may participate in appraisal
  proceedings until it is finally determined that he or she is not entitled to
  appraisal rights.

  Allocation of Costs

          The Court may determine the costs of an appraisal proceeding and tax
  them upon the parties as it deems equitable. Any PSGS Stockholder who incurs
  expenses in connection with the appraisal proceeding may apply to the Court to
  have such costs charged pro rata against the value of all of the shares
  entitled to an appraisal. Such costs may include, without limitation,
  reasonable attorney's fees and fees and expenses of experts. 

  Payment of Fair Value

          The Court shall direct payment of the fair value and interest, if any,
  by NUI and may enforce such decree as necessary. Holders of uncertificated
  stock shall receive payment forthwith, while holders of stock represented by
  certificates shall receive payment upon surrendering such certificates to NUI.

  Dismissal of Appraisal Rights

          The Court must approve any dismissal of any appraisal proceeding as to
  any PSGS Stockholder, and it may condition such dismissal upon terms deemed
  just by the Court. The appraisal rights of a PSGS Stockholder shall cease if a
  petition for appraisal is not timely filed or if such PSGS Stockholder
  delivers to NUI a written withdrawal of his or her demand for appraisal and an
  acceptance of the PSGS Merger. The PSGS Stockholder must deliver any such
  written withdrawal and acceptance either within sixty days after the Effective
  Time of the PSGS Merger or, with NUI's written approval, at some point
  thereafter.

                    COMPARATIVE PER SHARE FINANCIAL INFORMATION

          The following table sets forth certain unaudited per share information
  for NUI and PSGS, certain pro forma per share information for NUI after giving
  effect to the Mergers, and equivalent pro forma per share information for
  PSGS. Because the PSGS Merger will be accounted for as a purchase transaction,
  pro forma and equivalent per share income and dividend information is
  presented for only the most recent fiscal year for which financial information
  is available, which ended September 30, 1993. The data is based upon and
  should be read in conjunction with the NUI consolidated financial statements
  and the related notes thereto incorporated herein by reference; and the PSGS
  consolidated financial statements and the related notes thereto and the pro
  forma NUI financial data, each of which are included elsewhere in this Proxy
  Statement/Prospectus.

   For the Fiscal Year Ended
   September 30, 1993:
   Net Income                         $1.70       $1.63       $1.74       $4.11
   Dividends                          $1.59       $1.59       $1.54       $4.01
   Net Book Value (as of fiscal
   year end)                         $14.93      $15.83      $38.48      $39.89

  (a)  The pro forma NUI data per NUI share give effect to the PSGS Merger,
  pursuant to which the PSGS Stockholders will receive shares of NUI Common
  Stock equal in value to $71.50 for each share of PSGS Common Stock as set
  forth under "PSGS Merger-Basic Terms of Merger Agreement-Conversion of PSGS
  Common Stock"; followed by the EGC Merger. The pro forma NUI data are prepared
  on the basis of accounting for the PSGS Merger as a purchase transaction. The
  regulatory process establishes rates on the basis of historical net book
  value; therefore, (i) the underlying net assets of PSGS will be recorded as
  assets of NUI at their historical net book value as of the date of the PSGS
  Merger, (ii) the funded status of the PSGS pension plan will be recognized by
  recording an asset equal to the excess of plan assets at fair value as
  compared with the projected benefit obligation as of the date of acquisition
  ($1.4 million), (iii) the excess of the Merger Consideration over the recorded
  net assets will be recorded as a "plant acquisition adjustment" (amounting to
  approximately $6.8 million) and (iv) the plant acquisition adjustment will be
  amortized over a thirty-year period (amounting to approximately $225,000 per
  year) that approximates the remaining useful life of the utility plant
  acquired; all in accordance with generally accepted accounting principles.
  Furthermore, the pro forma NUI net income per share for the fiscal year ended
  September 30, 1993 excludes merger expenses incurred by PSGS ($226,000, net of
  $117,000 of income tax), which would have equated to $0.03 per NUI share.

  (b)  Represents the pro forma equivalent of one share of PSGS Common Stock
  calculated by multiplying the pro forma per share NUI data by the conversion
  ratio of 2.520 ($71.50 divided by $28.375, the assumed Average Market Price
  per share of NUI Common Stock). Furthermore, the pro forma NUI net income per
  equivalent PSGS share for the fiscal year ended September 30, 1993 excludes
  merger expenses incurred by PSGS ($226,000 net of $117,000 of income tax),
  which would have equated to $0.07 per equivalent PSGS share. The actual
  conversion ratio may be greater (but not greater than 3.0) or less (but not

                                        54
<PAGE>



  less than 2.4) depending upon the actual Average Market Price. See "PSGS
  Merger-Basic Terms of Merger Agreement-Conversion of PSGS Common Stock." In
  the event that the actual conversion ratio is 3.0, the pro forma net income
  and dividends per equivalent PSGS share would be $4.83 and $4.77,
  respectively, for the fiscal year ended September 30, 1993 and the net book
  value per PSGS equivalent share would be $46.89 at September 30, 1993. In the
  event that the actual conversion ratio is 2.4, the pro forma net income and
  dividends per equivalent PSGS share would be $3.93 and $3.82, respectively,
  for the fiscal year ended September 30, 1993 and the net book value per PSGS
  equivalent share would be $38.12 at September 30, 1993.

          The NUI Common Stock is listed on the NYSE and is traded under the
  symbol NUI.

          The following sets forth the closing market price per share for NUI
  Common Stock and the NUI closing market price per equivalent PSGS share on
  June 23, 1993, the last trading day before the announcement of the preliminary
  agreement between NUI and PSGS with respect to the PSGS Merger; on July 26,
  1993, the last trading day before the announcement of the signing of the
  Merger Agreement; and on January 3, 1994. There is no established public
  trading market for the PSGS Common Stock, therefore no PSGS Common Stock
  market price information is included herein.

  (a)  Represents the pro forma equivalent of one share of PSGS Common Stock
  calculated by multiplying the closing market price per share of NUI Common
  Stock by the conversion ratio of 2.520 ($71.50 divided by $28.375, the assumed
  Average Market Price per share of NUI Common Stock). The actual conversion
  ratio may be greater (but not greater than 3.0) or less (but not less than
  2.4) depending upon the actual Average Market Price. See "PSGS Merger-Basic
  Terms of Merger Agreement-Conversion of PSGS Common Stock." In the event that
  the actual conversion ratio is 3.0, the NUI market price per equivalent PSGS
  share would be $79.126 as of June 23, 1993, $87.001 as of July 26, 1993, and
  $78.00 as of January 7, 1994. In the event that the actual conversion ratio is
  2.4, the NUI market price per equivalent PSGS share would be $63.299 as of
  June 23, 1993, $69.599 as of July 26, 1993, and $62.40 as of January 7, 1994.

                    NUI COMMON STOCK DIVIDENDS AND PRICE RANGE

          NUI or its predecessor has paid cash dividends on the NUI Common Stock
  since 1893 and intends to continue to pay quarterly cash dividends. NUI's
  dividend policy is reviewed on an ongoing basis and is dependent upon NUI's
  expectations of future earnings, cash flow, financial condition, capital
  requirements and other factors. 

          Under the terms of its outstanding indebtedness, NUI is subject to
  restrictions that affect the payment of dividends on NUI Common Stock. In
  accordance with an NUI credit agreement, approximately $21.5 million of NUI's
  shareholders' equity was available as of September 30, 1993 for the payment of
  cash dividends. Consummation of the Mergers will not reduce the amount of

                                        55
<PAGE>



  NUI's shareholders' equity available for the payment of cash dividends.

          NUI is structured as a holding company and, as such, the funds
  required to enable NUI to pay dividends on NUI Common Stock are derived from
  the dividends paid by EGC on its common stock, all of which is held by NUI.
  Furthermore, after the Effective Time of the EGC Merger, all restrictions
  applicable to the payment of EGC dividends will be directly applicable to the
  payment of NUI dividends. Under the terms of its outstanding indebtedness, EGC
  is subject to restrictions on the payment of dividends on its common stock. As
  of September 30, 1993, the terms of EGC's indebtedness permitted EGC to pay
  cash dividends to NUI aggregating $47.3 million.

          As of October 31, 1993, the number of shares of NUI Common Stock
  outstanding was 8,205,412. Based on an assumed Average Market Price of $28.375
  per share of NUI Common Stock, on a pro forma basis as of October 31, 1993,
  reflecting the issuance in connection with the PSGS Merger of 594,318 shares
  of NUI Common Stock comprising the Merger Consideration, there would be
  8,799,730 shares of NUI Common Stock outstanding. Based on a $0.40 per share
  quarterly dividend payment, the aggregate quarterly dividend payment on
  8,799,730 shares would be $3.5 million.

          The NUI Common Stock is listed on the NYSE and is traded under the
  symbol NUI. The quarterly cash dividends paid and the reported closing price
  range per share of NUI Common Stock for the fiscal periods set forth below
  were as follows:

                           PRO FORMA NUI FINANCIAL DATA

          The pro forma NUI financial data give effect to the PSGS Merger,
  pursuant to which the PSGS Stockholders will receive shares of NUI Common
  Stock equal in value to $71.50 for each share of PSGS Common Stock as set
  forth in "PSGS Merger-Basic Terms of Merger Agreement-Conversion of PSGS
  Common Stock"; followed by the EGC Merger.

          The pro forma NUI financial data are prepared on the basis of
  accounting for the PSGS Merger as a purchase transaction. The regulatory
  process establishes rates on the basis of historical net book value;
  therefore, (i) the underlying net assets of PSGS will be recorded as assets of
  NUI at their historical net book value as of the date of the PSGS Merger, (ii)
  the funded status of the PSGS pension plan will be recognized by recording an
  asset equal to the excess of plan assets at fair value as compared with the
  projected benefit obligation as of the date of acquisition ($1.4 million),
  (iii) the excess of the Merger Consideration over the recorded net assets will
  be recorded as a "plant acquisition adjustment" (amounting to approximately
  $6.8 million) and (iv) the plant acquisition adjustment will be amortized over
  a thirty-year period (amounting to approximately $225,000 per year) that
  approximates the remaining useful life of the utility plant acquired; all in
  accordance with generally accepted accounting principles. Furthermore, the pro
  forma NUI net income for the fiscal year ended September 30, 1993 excludes
  merger expenses incurred by PSGS ($226,000, net of $117,000 of income tax),
  which would have equated to $0.03 per NUI share.

          The pro forma NUI financial data includes the financing of the
  purchase price for PSGS ($17,194,000), reflecting (1) the issuance of 594,318
  shares of NUI Common Stock based on an assumed Average Market Price of $28.375
  per share of NUI Common Stock ($16,864,000) and (2) the incurrence of
  short-term indebtedness to finance the fees and expenses estimated to be
  incurred in connection with the Mergers ($330,000). The additional short-term
  indebtedness will be incurred under existing lines of credit and is intended
  to be refinanced at a later date through the issuance of equity or long-term
  indebtedness or a combination thereof. In addition, the pro forma NUI
  financial data includes the short-term indebtedness of PSGS ($3,124,000) and
  long-term indebtedness of PSGS ($9,530,000) that will become the indebtedness
  of NUI as a result of the PSGS Merger. 

          No adjustments are required in the pro forma NUI financial data in
  order to give effect to the EGC Merger because EGC's financial data are
  already included in the historical NUI financial data.

          The pro forma NUI financial data provides information about the impact
  that the above mentioned transactions have on the historical financial data of
  NUI by showing how such transactions might have affected such historical
  financial data if the transactions had been consummated at the beginning of
  each period. However, the pro forma NUI financial data are not necessarily
  indicative of the results of operations or the financial position that would
  actually have been reported had the transactions been consummated at the
  beginning of each of the periods or that may be reported in the future. The
  pro forma NUI financial data should be read in conjunction with the financial
  statements and the notes thereto of NUI and PSGS that are included elsewhere
  in this Proxy Statement/Prospectus or incorporated herein by reference.

  available unused short-term credit lines and PSGS had approximately $3.0
  million of available unused short-term credit lines. In addition, NUI had
  Funds for Construction Held by Trustee amounting to $24.2 million,
  representing the unexpended portion of the net proceeds from $54.6 million of
  long-term debt incurred by NUI in October 1991 that is held by a trustee until
  drawn upon the incurrence of eligible construction expenditures.

  PSGS MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
  OF OPERATIONS

  Results of Operations

          Fiscal years ended September 30, 1993; 1992; 1991: Net income for the
  fiscal year ended September 30, 1993 amounted to $411,000, after merger
  expenses, compared to $1,053,000 for the prior fiscal year. The September 30,
  1992 net income reflects the sale of two propane operations which are
  discussed later in this section. Excluding the gain on this sale, the income
  from operations of $457,000 can be compared to the $411,000 for the year ended
  September 30, 1993.

          Natural gas gross margins increased in fiscal 1993 by $835,000, or
  8.7%, over those of the prior fiscal year. This increase was due to the
  approval of base rate increases in our Pennsylvania and Maryland operations,
  which were effective in January 1993 and June 1992 respectively, along with a
  4.9% increase in gas sales. The increased gas sales were due to the weather
  being 3% colder than last year, 3% customer growth in the residential and
  commercial market, and increased sales to our industrial customers.

          Other operating expenses increased $203,000, or 4%, over fiscal 1992.
  These expenses are made up of various expense items including natural gas
  distribution expense of $1,328,000, customer accounts expense of $953,000,
  sales expense of $182,000, administrative and general expense of $2,850,000
  and miscellaneous expenses  of $20,000, which includes the net impact of PSGS
  merchandise and jobbing activities. The distribution expense increased
  approximately $30,000 from last year due to increased payroll costs. Customer
  accounting expense increased $42,000 due to increased payroll and additional
  expense associated with installing a new natural gas billing system in our
  North Carolina operations. The increase in the sales expense of $10,000 was
  due to an increase in advertising for natural gas. The administrative and
  general expense increase of $159,000 was due to increased liability insurance
  ($86,000), primarily workmens compensation, and increased employee benefits
  ($49,000), primarily health insurance.

          Maintenance expense increased $33,000 in fiscal 1993. This increase is
  attributable to the revamping and upgrading of PSGS' cathodic protection
  system in the Maryland operations. Depreciation expense increased $124,000
  during the past fiscal year due to increased capital expansion along with
  approval of new depreciation rates in PSGS' North Carolina Division. The new
  rates will increase depreciation expense approximately $80,000 annually.
  General business taxes increased due to the increase in natural gas revenues. 

          Interest expense increased $142,000 over fiscal 1992 principally due
  to utilizing more of its revolving loan and lines of credit in 1993 to finance
  capital expenditures and operating costs. In fiscal 1992 financing needs were
  somewhat less due to the proceeds from the propane asset sale.

          Net income for PSGS for the fiscal year ended September 30, 1992, was
  $1,053,000 compared with a net loss of $228,000 in 1991. The 1992 net income
  includes a net gain of $596,000 for the sale of two of the PSGS' propane
  distribution operations which, when deducted from the total net income, leaves
  $457,000 of income from operations. Natural gas gross margin variances were
  the primary cause of the increased income from 1991 to 1992. 

          Natural gas gross margins increased by $1.6 million in 1992 as
  compared with 1991. This increase was due to increased throughput of 860,000

                                        66
<PAGE>



  Mcf brought about by 12% colder weather, even though the weather was 6% warmer
  than normal, and 3.5% customer growth. Volumes sold to PSGS' residential and
  commercial customers (core market) increased 18% over 1991 sales, and PSGS'
  industrial throughput rose 487,000 Mcf or 11%. Another significant contributor
  to the increased margins were base rate increases in PSGS' Maryland and North
  Carolina operations. 

          Other operating and maintenance expense increased to $5,724,000 in
  1992 compared with $5,604,000 in 1991. The various components of the 1992
  other operating expense included natural gas distribution expense  of
  $1,298,000, customer account expense of $911,000, sales expense of $173,000,
  administrative and general expense  of $2,691,000 and miscellaneous expenses
  of $57,000. PSGS' management concentrated effort to hold costs down, due to
  the erosion of earnings, resulted in a relatively small increase (2.1%) in
  these expenses. During the 1992 fiscal year wages were frozen for all
  non-contract personnel. The increase in distribution, customer accounting and
  sales expense remained relatively stable increasing less than 1%.
  Administrative and general expenses increased 6.5% over fiscal 1991, primarily
  from the increase in liability insurance ($44,000) and employee benefits
  ($24,000). Maintenance expense decreased slightly in 1992. The decrease
  reflects a return to a normalized level of maintenance expense after the
  significant upturn in 1990 due to a show cause order issued by the North
  Carolina Utilities Commission in October 1989 for alleged safety violations.
  The increase in depreciation expense from 1991 to 1992 of $146,000 was
  primarily the result of amortization of removal cost associated with the
  removal of a gas holder in PSGS' North Carolina operations. The cost of
  removal (approximately $900,000) is being amortized over a ten (10) year
  period which began in  October 1991.

          General business taxes were up slightly (2.6%) due to the overall
  operating revenue and payroll increases, on which the majority of these taxes
  are based. Income taxes have increased as a result of the increase in taxable
  income from 1991. Interest expense remained relatively stable in 1992 as
  compared to 1991. This stability was the result of reduced interest rates on
  PSGS' revolving loan and lines-of-credit, along with the reduced dependency on
  our lines-of-credit because of the proceeds received from the sale of the
  propane operations.

          In February 1992, PSGS sold two of its propane distribution
  operations, one located in Elizabeth City, North Carolina, and the other in
  Sayre, Pennsylvania. In recent years these two operations were faced with
  increased competition in an extremely competitive industry resulting in a
  reduced customer base, market share, and profitability. PSGS' management
  decided to sell these two operations to better focus on its primary business
  of natural gas distribution. The sale of these two operations, with net assets
  of $686,000, resulted in a gain of $596,000. PSGS still maintains a propane
  distribution operation in Reidsville, North Carolina, which has begun to
  experience the same competitive pressure felt by the operations which were
  sold. This operation reflected a net loss of $24,000 in fiscal 1992.

          In 1991, PSGS recorded approximately $317,000 in operating income from
  propane distribution operations. This income was primarily from the sale of
  "field inventory" located at customer sites. Historically, the propane located
  on the customer's premises was retained in PSGS' inventory and the customer
  was invoiced monthly for replacement volumes. This method of maintaining
  propane inventory had proven to be very costly due to increased carrying and
  operating costs. Therefore, in July 1991, PSGS sold this inventory,
  approximately 581,000 gallons, to its customers. This sale resulted in

                                        67
<PAGE>



  $305,000 of operating income.

          As mentioned previously, in October 1989, PSGS was issued a show cause
  order by the NCUC for alleged safety violations. PSGS, in order to correct
  these violations, increased its staff and used contractors to enhance and
  expedite its maintenance and replacement programs. The operation in the other
  jurisdictional areas of PSGS were reviewed and, where needed, additional costs
  were incurred to enhance those operations also. During fiscal 1990 operating
  and maintenance expenses increased approximately $778,000, of which $518,000
  related to the North Carolina operations. North Carolina added approximately
  15 employees in conjunction with work relating to the show cause order. These
  employees were used predominately to maintain the integrity of the natural gas
  system. These expenses are ongoing and will continue in future years. Approval
  of a rate increase which was effective October 1991 allowed for the recovery
  of these costs. In the interim, PSGS' earnings suffered.

          On March 28, 1991 PSGS reached a settlement agreement with the NCUC
  regarding each of the alleged safety violations. The agreement provided that
  PSGS would submit a main replacement and cathodic protection plan, along with
  periodic updates, to the NCUC. To date, PSGS has complied with all aspect of
  the terms of the settlement agreement, including maintaining and updating its
  replacement and protection plan.

  Capital Resources and Liquidity

          PSGS' operations are seasonal and this seasonality is reflected in the
  cash flow. Cash generated during the heating season is used during the summer
  months for completion of the annual construction program and to fill natural
  gas inventory used during the winter. In January 1993, PSGS renegotiated its
  revolving loan agreement with Commonwealth Bank. Under the renegotiated terms
  the maximum amount available increased from $4 million to $7 million. Proceeds
  may be utilized on a revolving basis for the first two years, at which time
  the then outstanding balance would be converted into a term loan repayable in
  equal monthly installments over the following ten years. Interest on amounts
  outstanding under the loan agreement will float with the bank's prime rate
  plus one-half of one percent for the first five years, at which time the rate
  will be renegotiated. Proceeds from the loan will be used to support PSGS's
  capital expenditures. PSGS continues to maintain $5.5 million in short-term
  lines-of-credit with three banks on which amounts borrowed bear an interest
  rate which approximates the bank's prime rate. At September 30, 1993, PSGS'
  capital structure was made up of 49% equity and 51% long-term debt.

          PSGS' capital expenditures were approximately $2.2 million in the
  fiscal year ended September 30, 1993. These expenditures have remained
  relatively stable over the past two years as our replacement program and
  growth requirements continue. In 1993 approximately 44% of these expenditures
  were used to support growth requirements, while another 30% was used for
  replacement of mains and services.

          PSGS' accounts receivable, net of the allowance for bad debt,
  increased $208,000 or 11% over the prior year's balance. This increase tracks
  the 11% increase in PSGS' operating revenue. Receivable balances in both
  fiscal 1993 and 1992 represent approximately 6.7% of the total revenues for
  the year. The allowance for unrecoverable receivables decreased slightly in
  fiscal 1993. PSGS collection procedures are regulated by the various utility
  commissions whose jurisdiction PSGS is under. Recently, PSGS has taken a more
  aggressive approach in collecting balances due from slow paying customers. The
  actual net write-offs for 1993 decreased $46,000 from those in 1992.

                                        68
<PAGE>



          The increase in the refundable income taxes was due to the loss for
  tax purposes in 1993. The carry back of this loss to the prior tax year
  resulted in the refund. The refundable taxes in 1992 were the result of tax
  overpayments in 1992.

          PSGS has purchase gas adjustment clauses filed with the various state
  utility commissions which regulate its operations. These adjustment clauses
  allow PSGS to recover gas costs on a dollar-for-dollar basis. Any over or
  under collections of these costs are deferred into the deferred gas cost
  adjustment account and either passed back to or collected from customers in
  subsequent periods. This account balance changed from a net overcollection
  (liability) in 1992 of $770,000 to a net undercollection (asset) in 1993 of
  $911,000.

          PSGS records refunds received from its pipeline supplier in a deferred
  credit account. These refunds are passed back to PSGS customers by applying a
  credit to the effective tariff rate. The decrease in the supplies refunds due
  customers and other deferred credits is the result of the net pass back of
  these refunds throughout the fiscal year.

  Accounting Standards

          FAS 106: In December 1990, the Financial Accounting Standards Board
  issued Statement No. 106, "Accounting for Postretirement Benefits Other Than
  Pensions." This statement requires companies to change from the cash basis of
  accounting to accruing for these costs during an employees' active years of
  service with PSGS.

          PSGS provides health and life insurance benefits to its retirees and,
  on October 1, 1993, switched to the accrual method. At January 1, 1993, the
  accumulated postretirement benefit obligation was approximately $700,000, and
  would result in approximately $100,000 in increased annual expense. PSGS plans
  to defer this expense and obtain recovery through future rate proceedings.
  Based on policy statements and discussions with the four state utility
  commissions whose jurisdiction PSGS is under, PSGS expects to receive
  favorable rate recovery of these costs.

          FAS 109: In February 1992, the Financial Accounting Standards Board
  issued SFAS No. 109, "Accounting for Income Taxes," which, among other things,
  requires enterprises to account for deferred income taxes using currently
  enacted rates. PSGS will adopt this new standard in fiscal 1994 and has
  estimated that net deferred tax liabilities include approximately $400,000
  which will be passed-back to customers through the rate making process. This
  adjustment is not expected to have a material effect on net income.

  Regulatory Matters

          PSGS implemented base rate increases in several of its operating
  divisions during the past eighteen months. The most recent increase was
  effective for its Pennsylvania operations for service rendered January 1,
  1993, and after. This increase culminated seven months of filings, data
  responses, and hearings which began in May of 1992. The final rates were
  designed to provide approximately $287,000 in additional annual operating
  revenues for the Valley Cities Gas Service Division.

          A base rate increase was also filed, approved, and implemented for the
  Maryland operations during the past eighteen months. Effective June 15, 1992,
  rates designed to produce approximately $118,000 in annual operating revenues

                                        69
<PAGE>



  were placed into effect. These increased rates were filed pursuant to a
  procedure providing for expedited rate relief if a company files according to
  the identical methodology of its previous litigated rate case and files within
  thirty-six months of its last request for base rate relief. This filing was
  made during May of 1992 and acted upon within one month.

          In October 1991, the NCUC approved an increase in base rates of
  $370,000 annually. On May 14, 1993, another request for base rate relief was
  submitted to the NCUC, seeking increased rates that would produce
  approximately $390,000 in additional annual operating revenues and authority
  to implement a weather normalization adjustment for the heat sensitive
  residential and commercial markets. On December 17, 1993, the NCUC granted
  approval to increase base rate revenues by $315,545. The approval was
  effective for service rendered on and after the order date. NCUC also approved
  PSGS' request to implement a weather normalization adjustment mechanism. This
  mechanism allows PSGS to adjust customers' monthly bills to offset the effect
  of any variance from normal weather, during the period November 1 through
  March 31.

          PSGS also received regulatory approval to begin billing 90% of the
  take-or-pay costs incurred for its New York operations. This approval,
  effective with June 1993 billing, culminates the necessary regulatory
  authorizations for take-or-pay cost recovery in each of PSGS' four natural gas
  operating divisions.

          Tennessee Gas Pipeline Company ("Tennessee") received FERC approval to
  implement the rates and tariff provisions necessary to comply with FERC's
  restructuring Order 636 effective September 1, 1993. Transcontinental Gas
  Pipeline Company ("Transco") filed its compliance tariffs on August 4, 1993,
  with a proposed effective date of November 1, 1993. PSGS has closely followed
  the proceedings and expects that the transition to the Order 636 environment
  will be a smooth one. The elections required to convert from a "bundled" sales
  service to "unbundled" sales and capacity related services were made
  previously. Transco's service restructuring was basically completed in late
  1990. Tennessee's restructuring was addressed through PSGS' "Cosmic
  Settlement" elections made in the spring of 1992, with one exception.

          Tennessee's Order 636 compliance abolishes Contract Demand Sales
  Service. PSGS' management has elected to convert its current CD-4 sales
  entitlement to firm transportation capacity upon 636 implementation. PSGS is
  currently negotiating for natural gas supply to support this firm
  transportation capacity. We expect to complete negotiations in the next
  several weeks and expect an arrangement will be reached which will provide
  long-term supply assurances at competitive prices.

          PSGS' management believes it has effectively dealt with the
  operational aspects of FERC Order 636 through its service elections discussed
  in this report and in previous reports. The elections have been designed to
  support PSGS' peak day, seasonal, and annual commitments to its customers.
  These service elections have also been designed to minimize the potential cost
  impact of new rate design mandates from the FERC. With Order 636
  implementation the pipelines will convert from a Modified Fixed Variable
  Pricing Method to the Straight Fixed Variable Pricing Scheme ("SFV"). Under
  SFV methodology rates are billed, by the pipelines, almost entirely on demand
  units in the form of a fixed monthly charge. Prior to 636 rates were billed
  partially on demand units and partially on commodity purchases. The more one
  used the more one paid. The majority of gas costs incurred upon 636
  implementation will be fixed with only slight variations related to the amount

                                        70
<PAGE>



  of gas purchased. Therefore, it is more important than ever to operate at a
  high load factor in order to reduce the average unit cost. PSGS' management
  believes that it has prepared its service elections in a manner that will
  provide adequate supplies at competitive prices to our customers for now and
  in the future.

  Certain Environmental Matters

          PSGS' historical operations included the operation of coal
  gasification sites, where through a series of processes gas was manufactured
  from coal and oil. The United States Environmental Protection Agency (the
  "EPA") and various state regulatory authorities have over the years been
  investigating former coal gas manufacturing facilities generally because of
  the potential for those operations to have generated hazardous
  substance-containing waste materials and by-products. PSGS historically
  operated ten such facilities, only three of which PSGS still owns. The other
  seven were, over the years, sold and are currently owned and controlled by
  other entities. Manufactured gas plant activities at PSGS' facilities were
  discontinued in or about 1946, when a more cost-efficient alternative became
  available - propane.

          Four of the ten former sites are currently listed on the EPA's CERCLIS
  List, where they eventually will be subjected to some level of investigation
  and, if necessary, remediation by any one of the state regulatory authorities
  in which they reside or the EPA. One of these sites, as a result of a
  Preliminary Assessment completed by the North Carolina Department of
  Environment, Health, and Natural Resources, Division of Solid Waste
  Management, has been recommended for a Screening Site Investigation. The fact
  that the sites appear on the CERCLIS List is not indicative of their status;
  nor does it signify that the sites will be placed on the National Priorities
  List of sites designated for environmental cleanup. PSGS is currently
  participating in the formation of a state coalition whose purpose is the
  establishment of a uniform program and framework for addressing manufactured
  gas plant sites in North Carolina.

          Nevertheless, the sites do represent a source of potential
  environmental claims. While it is not possible at this time to estimate the
  amount of liability, if any, that could result from these matters, PSGS will
  continue to monitor developments and, if appropriate, record accruals when
  required.

                                   NUI BUSINESS

          NUI and its subsidiaries are engaged primarily in the distribution of
  natural gas in New Jersey and Florida. The principal executive offices of NUI
  are located at 550 Route 202-206, Box 760, Bedminster, NJ 07921-0760;
  telephone: (908) 781-0500.

          NUI is an exempt public utility holding company under the PUHCA. NUI
  was incorporated in New Jersey in 1969. NUI's principal operating subsidiary,
  EGC, was organized in 1855. NUI currently serves approximately 320,000
  customers in two states. The New Jersey Division does business as
  Elizabethtown Gas Company and the Florida Division does business as City Gas
  Company of Florida.

          In 1958, the Public Service Commission of Maryland approved PSGS'
  merger with the Elkton Gas Company (which was incorporated in Maryland in
  1920) and authorized PSGS to distribute gas in portions of Cecil County,
  including the Town of Elkton. In 1958 and in 1961, the Public Service
  Commission of Maryland extended PSGS' service territory to include the third,
  fourth and fifth election districts of Cecil County. The current service
  territory is a contiguous region in the northeast corner of Cecil County
  containing the entire Town of Elkton and extending to the Pennsylvania State
  line to the north and the Delaware State line to the east.

          PSGS' Elkton Gas Service Division purchases all of its gas
  requirements from the Eastern Shore Natural Gas Company.

  Waverly Gas Service

          PSGS, through its Waverly Gas Service Division, distributes natural
  gas in the Village of Waverly, New York and surroundings. It previously
  existed as The Gas Light Company of Waverly, a wholly-owned subsidiary of
  PSGS. By order of the Public Service Commission of the State of New York
  issued on February 17, 1959, The Gas Light Company of Waverly was merged with
  and into PSGS. The Waverly Gas Service Division is supplied with gas from the
  Valley Cities Gas Service Divisional System, operating in Pennsylvania, as its
  operations are supervised from the Sayre operating office. The Village of
  Waverly is located approximately one mile north of Sayre, immediately across
  the Pennsylvania/New York State border. The Waverly Gas Service Division
  serves approximately 1,264 customers in New York.

  Gas Supply

          In 1992, the FERC issued Order No. 636 that mandates the unbundling of
  interstate pipeline sales and transportation and establishes certain open
  access transportation regulations effective in 1993. Two of PSGS' three
  principal pipeline suppliers have been operating as open access pipelines
  under the FERC's Order 436. However, Eastern Shore Natural Gas Company has not
  elected open access.

          Tennessee received FERC approval to implement the rates and tariff
  provisions necessary to comply with FERC's restructuring Order 636 effective
  September 1, 1993. Transcontinental filed its compliance tariffs on August 4,
  1993, with a proposed effective date of November 1, 1993. PSGS has closely
  followed the proceedings and expects that the transition to the Order 636
  environment will be a smooth one. The elections required to convert from a
  "bundled" sales service to "unbundled" sales and capacity related services
  were made previously. Transco's service restructuring was basically completed
  in late 1990. Tennessee's restructuring was addressed through PSGS' "Cosmic
  Settlement" elections made in the spring of 1992, with one exception.

          Tennessee's Order 636 compliance abolishes Contract Demand Sales
  Service. PSGS' management has elected to convert its current CD-4 sales
  entitlement to firm transportation capacity upon 636 implementation. PSGS is
  currently negotiating for natural gas supply to support this firm
  transportation capacity. PSGS expects to complete negotiations in the next
  several weeks and expect an arrangement will be reached which will provide
  long-term supply assurances at competitive prices.

          PSGS' management believes it has effectively dealt with the
  operational aspects of FERC Order 636 through its service elections discussed
  in this report and in previous reports. The elections have been designed to
  support PSGS' peak day, seasonal, and annual commitments to its customers.
  These service elections have also been designed to minimize the potential cost
  impact of new rate design mandates from the FERC. With Order 636
  implementation the pipelines will convert from a Modified Fixed-Variable
  Pricing Method to the Straight Fixed Variable Pricing Scheme ("SFV"). Under
  SFV methodology rates are billed, by the pipelines, almost entirely on demand
  units in the form of a fixed monthly charge. Prior to 636 rates were billed
  partially on demand units and partially on commodity purchases. The more one
  used the more one paid. The majority of gas costs incurred upon 636
  implementation will be fixed with only slight variations related to the amount
  of gas purchased. Therefore, it is more important than ever to operate at a
  high load factor in order to reduce the average unit cost. PSGS' management
  believes that it has prepared its service elections in a manner that will

                                        76

  provide adequate supplies at competitive prices to our customers for now and
  in the future.

  Capital Expenditures

          Capital expenditures, which consist primarily of expenditures to
  expand and upgrade PSGS's gas distribution systems, were $3,707,000 in fiscal
  1991, $2,127,000 in fiscal 1992 and $2,172,000 in fiscal 1993. Approximately
  $7,251,000 of these capital expenditures were for construction relating to new
  customers and additional distribution, storage and other gas plant facilities.
  PSGS's capital expenditures are expected to approximate $3,238,000 in fiscal
  1994.

  Seasonal Aspects

          Sales of gas to some classes of customers are effected by variations
  in demand due to changes in weather conditions, including normal seasonal
  variations throughout the year. The demand for gas for heating purposes is
  closely related to the severity of the winter heating season. Seasonal
  variations effect short-term cash requirements.

  Persons Employed

          As of September 30, 1993, PSGS employed 145 persons. As of September
  30, 1993, the International Brotherhood of Teamsters, Chauffeurs, Warehousemen
  and Helpers (the "Teamsters") represented 19 employees of the Valley Cities
  Gas Service Division and the International Brotherhood of Electrical Workers
  (the "IBEW") represented 51 employees of the North Carolina Division. The
  current labor contract with the Teamsters expires on October 1, 1996. It was
  approved by the bargaining unit on October 4, 1993. The current labor contract
  with the IBEW expires on August 30, 1995. It was approved by the bargaining
  unit on September 1, 1992.

  Competition

          PSGS competes with distributions of other fuels and forms of energy,
  including electricity, fuel oil and propane, in all portions of the territory
  served. Electricity and oil are the primary competition to natural gas in the
  residential and commercial markets where the primary uses of energy are for
  space heating, water heating, cooking and clothes drying. In recent years,
  natural gas has enjoyed a competitive price advantage over electricity and oil
  for such purposes, which continues to allow PSGS to obtain a significant share
  of the residential and commercial sectors of the new construction market.

          In addition, open access to the interstate pipeline transmission
  system allow certain industrial customers to purchase gas from alternative
  sources for transportation through PSGS distribution systems and may allow
  certain industrial customers to bypass PSGS' systems all together by
  connecting directly to a gas pipeline. PSGS seeks to remain competitive in the
  industrial markets through flexible rate and transportation tariffs.

  Franchises

          PSGS holds non-exclusive municipal franchises and other consents which
  enable it to provide natural gas in the territories it serves. PSGS intends to
  renew these franchises and consents as they expire.

                           INDEPENDENT AUDITORS' REPORT



  To the Shareholders and Board of Directors
          of the Pennsylvania & Southern Gas Company
          Sayre, Pennsylvania

          We have audited the accompanying consolidated balance sheets and
  statements of consolidated capitalization of PENNSYLVANIA & SOUTHERN GAS
  COMPANY AND SUBSIDIARY as of September 30, 1993 and 1992, and the related
  consolidated statements of income (loss), shareholders' equity, and cash flows
  for each of the three years in the period ended September 30, 1993. These
  financial statements are the responsibility of the Company's management. Our
  responsibility is to express an opinion on these financial statements based on
  our audits.

          We conducted our audits in accordance with generally accepted auditing
  standards. Those standards require that we plan and perform the audit to
  obtain reasonable assurance about whether the financial statements are free of
  material misstatement. An audit includes examining, on a test basis, evidence
  supporting the amounts and disclosures in the financial statements. An audit
  also includes assessing the accounting principles used and significant
  estimates made by management, as well as evaluating the overall financial
  statement presentation. We believe that our audits provide a reasonable basis
  for our opinion.

          In our opinion, the consolidated financial statements referred to
  above present fairly, in all material respects, the financial position of
  Pennsylvania & Southern Gas Company and Subsidiary as of September 30, 1993
  and 1992, and the results of their operations and their cash flows for each of
  the three years in the period ended September 30, 1993, in conformity with
  generally accepted accounting principles.

                PENNSYLVANIA & SOUTHERN GAS COMPANY AND SUBSIDIARY
                    NOTES TO CONSOLIDATED FINANCIAL STATEMENTS




  1.      SIGNIFICANT ACCOUNTING POLICIES

          Principles of Consolidation

          The accompanying consolidated financial statements include the
          accounts of the Company and its wholly owned subsidiary, Rockingham
          Exploration Company. Rockingham Exploration is in the process of
          disposing of its assets. The effect of this transaction will not be
          significant.

          Accounting Records

          The Company maintains its accounting records in conformity with the
          uniform system of accounts prescribed by the Federal Energy Regulatory
          Commission and the Public Service Commissions of the states of New
          York, Pennsylvania, North Carolina and Maryland.

          Regulatory Matters

          The Company is deferring for accounting and rate-making purposes
          differences between purchased gas costs and the settlement of such
          costs which, through the application of annual purchased gas
          adjustment clauses or similar tariff provisions, are expected to be
          settled through changes in operating revenues in subsequent periods.

          The Company has received refunds from its natural gas suppliers which
          have been deferred pursuant to the various state regulatory
          commissions' rules and regulations. In accordance with the
          instructions of the state regulatory commission, the Company is
          collecting or refunding such amounts to its affected customers. The
          amounts required to be collected or refunded within one year are
          included as current assets or liabilities.

          Revenues

          Operating revenues are recorded on the basis of service rendered and
          include unbilled and accrued revenues through the end of the
          accounting period.

          Income Taxes

          The Company files a consolidated federal income tax return with its
          wholly owned subsidiary. Where permitted by the various state
          regulatory commissions for rate-making purposes, the Company provides
          deferred income taxes relating to differences in the timing of the
          recognition of certain items of income and expense for book and tax
          purposes.

          Investment tax credits are deferred and amortized over the useful
          service lives of the related assets. The Tax Reform Act of 1986
          eliminated the investment tax credit.

              NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)




          Cash Equivalents

          The Company considers all highly liquid investments with an original
          maturity of three months or less to be cash equivalents.

          Restricted Cash Deposits

          In accordance with certain regulatory requirements the company is
          required to deposit certain funds received in interest-bearing
          accounts with a corresponding amount included in other deferred
          credits. These funds are restricted for uses prescribed by regulatory
          authorities.

          Inventories

          Inventories are stated at the lower of cost or market based on average
          cost (natural gas in storage and materials and supplies), last-in,
          first-out cost (propane gas) and first-in, first-out cost
          (appliances).

          Plant, Property and Depreciation

          The cost of new plant and property and expenditures for major renewals
          and betterments are capitalized and depreciated on the straight-line
          method over estimated service lives. The annual composite depreciation
          rate is approximately three percent for utility plant. The estimated
          service lives used range from 3 to 51.

          When utility assets are retired or otherwise disposed of, the original
          cost is eliminated from the accounts. In the case of retirements,
          other than abnormal retirements, the difference between cost and
          accumulated depreciation, as adjusted for the cost of removal, is
          accounted for through the accumulated depreciation account.

          Repairs of all property, plant and equipment as well as minor 
          replacements are charged to maintenance expense as incurred.

          Net Income (Loss) Per Share of Common Stock

          Net income (loss) per share of common stock is based on the weighted
          average number of common shares outstanding (235,857 shares for all
          periods presented).

  3.      EMPLOYEES' BENEFIT PLAN

          The Company has a non-contributory defined benefit pension plan which
          covers all full-time employees. The benefits are based on years of
          service and the highest average compensation over sixty consecutive
          months during the last ten years of employment. The Company's policy
          is to fund the plan as required. Contributions are intended to provide
          not only for benefits attributed to service to date but also for those
          expected to be earned in the future.

          Net periodic pension cost for the years ended September 30, included
          the following components:
                                                 1993       1992       1991

          The weighted-average discount rate and rate of increase in future
          compensation levels used in determining the actuarial present value of
          the projected benefit obligation were 7.5% and 5.5% and 8.5% and 5.5% 
          in 1993 and 1992, respectively. The expected long-term rate of return
          on assets was 8% and 8.5% in 1993 and 1992, respectively.

          The Company has an employer earnings and investment plan as allowed 
          under Section 401(k) of the Internal Revenue Code. Under this Plan,
          each employee can defer up to 15% of compensation. The Company matches
          50% of the deferral, not to exceed 2% of the employees' compensation.
   
          The Company's matching contributions for 1993, 1992 and 1991 were
          approximately $55,000, $62,000, and $64,000, respectively. In addition
          to the matching contribution, the Company's Board of Directors
          approved a further contribution, to be made annually, to the account
          of each employee of the Company equal to 3% of the employees' salary
          and wages for the year, totalling approximately $111,000 in fiscal
          year 1993, $112,000 in fiscal year 1992 and $109,000 in fiscal year
          1991.

  4.      POSTRETIREMENT BENEFITS OTHER THAN PENSIONS

          In December of 1990, the Financial Accounting Standards Board issued
          SFAS No. 106, "Employers' Accounting for Postretirement Benefits Other
          Than Pensions" which will require the Company to accrue the costs of
          the retiree health and other retirement benefits during the working 
          careers of active employees effective for fiscal year 1994. The
          Company currently provides retirees with certain life and health
          insurance benefits which, on a "pay-as-you-go" basis amounted to
          approximately $19,000, $17,000, and $16,000 in 1993, 1992, and 1991
          respectively.

          The Company will adopt the standard as of October 1, 1993 and expects
          to amortize the transition obligation of approximately $700,000 over
          approximately 22 years. The related impact on health care benefits
          expense after adoption is expected to be in excess of the current
          "pay-as-you-go" amount by approximately $100,000. In 1993, the
          Emerging Issues Task Force (the "EITF") reached a consensus with
          respect to accounting for postretirement benefits. Based upon
          preliminary discussions with regulators, the Company expects to
          recover costs within the guidelines of the EITF.

  5.      SHORT-TERM NOTES PAYABLE

          The Company has available unsecured lines of credit aggregating
          $5,500,000 at September 30, 1993. These lines are renegotiated
          annually and may be withdrawn at the Banks' option and all outstanding
          balances are due on demand. As of September 30, 1993 and 1992, there
          was $2,475,000 and $1,825,000 outstanding, respectively, bearing
          various interest rates which in  aggregate approximate prime.

  6.      LONG-TERM DEBT

          The first mortgage bonds consist of two separate series which are
          collateralized by certain utility properties. Furthermore, the bond
          indenture contains a number of restrictive covenants, including
          limitations on both the amount of dividends paid and any additional
          amounts of long-term debt issued by the Company.

          In addition, the Company has a revolving loan agreement with a Bank
          which makes a total of $7,000,000 available to the Company. At
          September 30, 1993 there was approximately $5,525,000 outstanding
          under this agreement. In January 1993, certain terms of the agreement
          were renegotiated including an increase in amount available from
          $4,000,000 at September 30, 1992 and a change in the minimum monthly
          payment requirement from 1/36 to 1/120 of the outstanding principal
          balance beginning in January 1995. Interest is payable monthly and
          bears interest at prime plus 1/2% (6-1/2% at September 30, 1993),
          through February 1998, which will be renegotiated for years
          subsequent. The Company's primary use of these funds is to support
          costs of capital replacement and expansion.

          The Company's income tax expense differs from the amount which would
          be provided by applying the federal statutory rate to income before
          tax. The reasons for the difference (expressed as a percentage of
          pre-tax income) are as follows:

                                           1993      1992      1991

         In February 1992, the Financial Accounting Standards Board issued SFAS 
          No. 109, "Accounting for Income Taxes," which, among other things,
          requires enterprises to account for deferred income taxes using
          currently enacted rates. The Company will adopt this new standard in
          fiscal 1994 and has estimated net deferred tax liabilities to include
          approximately $400,000 which will be passed-back to customers through
          the rate-making process. This adjustment is not expected to have a
          material effect on net income.

  10.     TAKE OR PAY CHARGES

          In 1993 the New York State Public Service Commission approved recovery
          of 90% of certain take-or-pay charges, and in 1992 the Pennsylvania
          Public Utilities Commission also approved 90% recovery of these
          charges. The Company expensed approximately $15,000 and $128,000 in
          1993 and 1992, respectively, representing the amount of costs which
          were not recoverable.

  11.     SALE OF CERTAIN PROPANE OPERATIONS

          In February 1992, the Company sold, for $1,657,000, two of their

              NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)




          propane operations which included equipment, inventories and accounts
          receivable. As part of the sale and in consideration of not competing
          with the buyer, the Company will also receive $20,000 for each of the
          next five years. These amounts will be recorded as part of income in
          the year received. The total gain on the sale was $971,000.

  12.     COMMITMENTS AND CONTINGENCIES

          The Company's historical operations included the operation of coal
          gasification sites, where through a series of processes gas was
          manufactured from coal and oil. The U. S. Environmental Protection
          Agency and various state regulatory authorities have over the years
          been investigating former coal gas manufacturing facilities generally,
          because of the potential for those operations to have generated
          hazardous substance-containing waste materials and by products. The
          Company historically operated ten such facilities, only three of which
          the Company still owns. The other seven were, over the years, sold and
          are currently owned and controlled by other entities. Manufactured gas
          plant activities at the Company's facilities were discontinued in or
          about 1946, when a more cost-efficient alternative became available -
          propane.

          Four of the ten former sites are currently listed on the United Stated
          Environmental Protection Agency's CERCLIS List, where they eventually
          will be subjected to some level of investigation by any one of the
          state regulatory authorities in which they reside or the EPA. One of
          these sites, as a result of a Preliminary Assessment completed by the
          North Carolina Department of Environment, Health, and Natural
          Resources, Division of Solid Waste Management, has been recommended
          for a Screening Site Investigation. The fact that the sites appear on
          the CERCLIS List is not indicative of their status; nor does it
          signify that the sites will be placed on the National Priorities List
          of sites designated for environmental cleanup. The Company is
          currently participating in the formation of a state coalition whose
          purpose is the establishment of a uniform program and framework for
          addressing manufactured gas plant sites in North Carolina.

          Nevertheless, the sites do represent a source of potential
          environmental claims. While it is not possible at this time to
          estimate the amount of liability, if any, that could result from these
          matters, the Company will continue to monitor developments and, if
          appropriate, record accruals when required.

  13.     PROPOSED MERGER

          On July 27, 1993, the Board of Directors, subject to shareholder
          approval, agreed to the merger of Pennsylvania & Southern Gas Company
          with and into NUI Corporation pursuant to the terms and conditions of
          an "Agreement and Plan of Merger" (the "Agreement"). Pursuant to the
          "Agreement" each share of PSGS stock will be exchanged for shares of
          NUI Corporation Common Stock based upon a formula contained therein.

           EFFECTS OF THE MERGER ON PURCHASER AND COMPANY COMMON STOCK;
                             EXCHANGE OF CERTIFICATES

          3.1.  Effect on Purchaser and Company Common Stock. At the Effective
  Time, by virtue of the Merger and without any action on the part of the
  Company or the Purchaser or the holder of any of the following securities:

          (a)  Each share of Purchaser Common Stock issued and outstanding

                                        A-5
<PAGE>



  immediately prior to the Effective Time shall remain unchanged.

          (b)  Each share of Company Common Stock which immediately prior to the
  Effective Time is owned directly or indirectly in the treasury of the Company,
  by any direct or indirect Subsidiary of the Company or by the Purchaser or any
  direct or indirect Subsidiary of the Purchaser shall be cancelled and retired,
  and no payment shall be made with respect thereto.

          (c)  Each share of Company Common Stock issued and outstanding
  immediately prior to the Effective Time (other than shares of Company Common
  Stock to be cancelled pursuant to Section 3.1(b) and Dissenting Shares) shall
  be converted into the right to receive the number of shares of Surviving
  Common Stock, or fraction thereof rounded to the nearest .0001 of a share of
  Surviving Common Stock, equal to the number determined by dividing (i) $71.50
  by (ii) the arithmetic average of the daily closing price per share of
  Purchaser Common Stock for the twenty trading days immediately prior to the
  Closing Date as reported on the composite tape of the NYSE (the "Average
  Market Price");  provided, that if the applicable number of shares of
  Surviving Common Stock to be exchanged for each share of Company Common Stock
  in the Merger is equal to or greater than 3.0 shares, the number of shares of
  Surviving Common Stock exchanged for each share of Company Common Stock in the
  Merger shall be equal to 3.0 shares, provided, further, that if the applicable
  number of shares of Surviving Common Stock to be exchanged for each share of
  Company Common Stock in the Merger is equal to or less than 2.4 shares, the
  number of shares of Surviving Common Stock exchanged for each share of Company
  Common Stock in the Merger shall be equal to 2.4 shares (the "Merger
  Consideration"). In the event that during the period commencing on the date of
  this Agreement and ending on the Closing Date, the Purchaser takes any of the
  following actions: (i) pays a dividend or makes a distribution on Purchaser
  Common Stock, in each case, in shares of Purchaser Common Stock; (ii)
  subdivides the outstanding shares of Purchaser Common Stock into a greater
  number of shares, or (iii) combines the outstanding shares of Purchaser Common
  Stock into a smaller number of shares, the maximum and minimum number of
  shares of Purchaser Common Stock issuable as Merger Consideration, as set
  forth in the first and second provisos, respectively, of the immediately
  preceding sentence of this Section 3.1(c), shall on the effective date of such
  action, each be adjusted by multiplying such number by a fraction (A) the
  numerator of which shall be the number of shares of Purchaser Common Stock
  outstanding immediately following such action and (B) the denominator of which
  shall be the number of shares of Purchaser Common Stock outstanding
  immediately prior to such action.

          3.2.  Dissenting Shares. (a)  Notwithstanding any provision of this
  Agreement other than Section 3.2(b) to the contrary, any shares ("Dissenting
  Shares") of Company Common Stock held by a holder who has demanded and
  perfected his or her right to receive payment for the fair value of his or her
  shares in accordance with Section 262 of the DGCL (a "Dissenting
  Shareholder"), and as of the Effective Time has not effectively withdrawn or
  lost his or her right to receive payment for the fair value of his or her
  shares, shall not be converted into or represent a right to receive the Merger
  Consideration as otherwise provided in this Article 3, but the holder thereof
  shall only be entitled to such rights as are granted by Section 262 of the
  DGCL. 

          (b)  Notwithstanding the provisions of Section 3.2(a), if any holder
  of shares of Company Common Stock who demands the right to receive payment for
  the fair value of his or her shares under the DGCL shall effectively withdraw
  or lose (through failure to perfect or otherwise) his or her right to receive

                                        A-6
<PAGE>



  payment for the fair value of his or her shares of Company Common Stock, then
  as of the Effective Time or the occurrence of such event, whichever last
  occurs, such holder's shares of Company Common Stock shall automatically be
  converted into and represent only the right to receive the Merger
  Consideration as otherwise provided in this Article 3. 

          3.3.  Stock Transfer Books. At the Effective Time, the stock transfer
  books of the Company shall be closed and there shall be no further
  registration of transfers of shares of Company Common Stock thereafter on the
  records of the Company. If, after the Effective Time, Certificates are
  presented to the Surviving Corporation, they shall be cancelled and exchanged
  for the Merger Consideration as provided in this Article 3 (unless such
  Certificates represent Dissenting Shares).

          3.4.  Exchange of Shares of Company Common Stock. (a)  At the
  Effective Time, the Surviving Corporation shall cause to be deposited with the
  Exchange Agent that number of shares of Surviving Common Stock to be issued in
  the Merger as contemplated by Section 3.1(c). The Exchange Agent shall agree
  to hold such shares in trust and deliver such shares as contemplated by
  Section 3.1 and upon such additional terms as may be agreed upon by the
  Exchange Agent, the Company and the Purchaser prior to the Effective Time.

          (b)  As promptly as practicable after the Effective Time, the
  Surviving Corporation shall mail or cause the Exchange Agent to mail to each
  holder of outstanding Company Common Stock of record as of the Effective Time
  (i) a letter of transmittal (which shall specify that delivery shall be
  effected, and risk of loss and title to the shares of Company Common Stock
  shall pass, only upon proper delivery of the Certificates representing such
  shares of Company Common Stock to the Exchange Agent and shall be in such form
  and have such other provisions as the Purchaser and the Company may reasonably
  specify) and (ii) instructions for use in effecting the exchange of the
  Certificates for payment therefor as hereinabove provided. Upon surrender to
  the Exchange Agent of a Certificate, together with such letter of transmittal
  duly executed, the holder of such Certificate shall be entitled to receive in
  exchange therefor certificates registered in the name of such holder
  representing the number of whole shares of Surviving Common Stock into which
  any shares of Company Common Stock previously represented by the surrendered
  Certificate shall have been converted at the Effective Time (plus a check
  payable to such holder representing the payment of cash in lieu of fractional
  shares of Surviving Common Stock determined as set forth in Section 3.4(e)).
  Until surrendered as contemplated by the preceding sentence, each Certificate
  (other than Certificates representing shares of Company Common Stock cancelled
  pursuant to Section 3.1(b) and Dissenting Shares) that immediately prior to
  the Effective Time shall have represented any shares of Company Common Stock
  shall be deemed at and after the Effective Time to represent only the right to
  receive upon such surrender, the certificates of Surviving Common Stock
  contemplated by the preceding sentence, and such Certificate shall then be
  cancelled. No interest will be paid or accrued on the cash payable, if any,
  upon the surrender of the Certificate.

          (c)  If any certificates representing shares of Surviving Common Stock
  is to be paid to or issued in a name other than the Person in whose name the
  Certificate surrendered is registered, it shall be a condition of payment that
  the Certificate so surrendered shall be properly endorsed or otherwise in
  proper form for transfer and that the Person requesting such payment shall
  (i) pay transfer or other Taxes required by reason of the issuance of a
  certificate representing shares of Surviving Common Stock in any name to a
  Person other than the registered holder of the Certificate surrendered or

                                        A-7
<PAGE>



  (ii) establish to the satisfaction of the Surviving Corporation that such Tax
  has been paid or is not applicable.

          (d)  Any instruments remaining with the Exchange Agent eighteen months
  following the Effective Time shall be returned to the Surviving Corporation,
  after which time former shareholders of the Company, subject to applicable
  law, shall look only to the Surviving Corporation for payment of the Merger
  Consideration due hereunder, without interest thereon. 

          (e)  No certificates or scrip representing fractional shares of
  Surviving Common Stock shall be issued upon the surrender for exchange of
  Certificates. No dividend or distribution of the Surviving Corporation shall
  relate to any fractional share and such fractional share interests shall not
  entitle the owner thereof to vote or to any rights of a shareholder of the
  Surviving Corporation. In lieu of any fractional share of Surviving Common
  Stock, there shall be paid to each holder of shares of Company Common Stock
  entitled to a fractional share of Surviving Common Stock an amount of cash,
  without interest, determined by multiplying such fraction by the Average
  Market Price. No such payment shall be made to the holder of any unsurrendered
  Certificates until such Certificates shall be surrendered as provided herein.

          (f)  No dividends or other distributions declared after the Effective
  Time with respect to Surviving Common Stock and payable to the holders of
  record thereof after the Effective Time shall be paid to the holder of any
  unsurrendered Certificates with respect to which the shares of Surviving
  Common Stock shall have been issued in the Merger until such Certificates
  shall be surrendered as provided herein, but (i) upon such surrender there
  shall be paid to the shareholder in whose name certificates representing
  Surviving Common Stock shall be issued the amount of dividends theretofore
  paid with respect to such whole shares of Surviving Common Stock as of any
  record date subsequent to the Effective Time and (ii) at the appropriate
  payment date, or as soon as practicable thereafter, there shall be paid to
  such shareholder the amount of dividends with a record date on or after the
  Effective Time but prior to surrender and a payment date subsequent to
  surrender payable with respect to such whole shares of Surviving Common Stock,
  subject in any case to any applicable escheat laws. No interest shall be
  payable with respect to the payment of such dividends on surrender of
  outstanding Certificates.

          (g)  In the event any Certificate shall have been lost, stolen or
  destroyed, upon the making of an affidavit of that fact by the Person claiming
  such Certificate to be lost, stolen or destroyed, the Surviving Corporation
  will issue in exchange for such lost, stolen or destroyed Certificate the
  Merger Consideration deliverable in respect thereof in accordance with this
  Article 3. When authorizing such issuance of the Merger Consideration in
  exchange therefor, the Board of the Surviving Corporation may, in its
  reasonable discretion and as a condition precedent to the issuance thereof,
  require the owner of such lost, stolen or destroyed Certificate to give the
  Surviving Corporation a bond in such reasonable amount as the Surviving
  Corporation may direct as indemnity against any claim that may be made against
  the Surviving Corporation with respect to the Certificate alleged to have been
  lost, stolen or destroyed.

                          REPRESENTATIONS AND WARRANTIES
                                 OF THE PURCHASER

          The Purchaser hereby represents and warrants to the Company as
  follows: 

          4.1.  Corporate Status. Each of the Purchaser and EGC is a corporation
  duly incorporated, validly existing and in good standing under the laws of the
  State of New Jersey and has the corporate power and authority to carry on its
  business as now being conducted. Each of the Purchaser and EGC is duly
  qualified as a foreign corporation to do business, and is in good standing, in
  each jurisdiction where the properties owned, leased or operated, or the
  businesses conducted, by it require such qualification, except for such
  failures to be qualified or to be in good standing, if any, which when taken
  together with all such other failures of the Purchaser and EGC have not had
  and, so far as can be reasonably foreseen at this time, will not have a
  Material Adverse Effect on the Purchaser and its Subsidiaries taken as a
  whole. The Purchaser has previously delivered to the Company complete and
  correct copies of its Articles of Incorporation, as amended, and By-Laws, as
  amended.

          4.2.  Capitalization of the Purchaser. The authorized capital stock of
  the Purchaser consists of 15,000,000 shares of Purchaser Common Stock and
  5,000,000 shares of preferred stock. As of June 30, 1993, (a) 8,167,525 shares
  of Purchaser Common Stock were issued and outstanding, (b) 49,539 shares of
  Purchaser Common Stock were held in the treasury of the Purchaser or owned by
  any Subsidiary of the Purchaser and (c) 266,674 shares of Purchaser common
  stock were reserved for issuance pursuant to Purchaser's employee benefit
  plans (including stock option plans) and the Purchaser's dividend reinvestment
  and stock purchase plan. There are no issued or outstanding shares of
  preferred stock of the Purchaser. All outstanding shares of Purchaser Common
  Stock are validly issued, fully paid and nonassessable. The shares of
  Surviving Common Stock to be issued in the Merger pursuant to Article 3 will,
  at the Effective Time, be duly authorized, and when issued pursuant to this
  Agreement, will be validly issued, fully paid and nonassessable and will not
  have been issued in violation of any preemptive rights. Except for this
  Agreement and as disclosed in this Section 4.2, there are no outstanding
  subscriptions, securities, options, warrants, rights or other agreements or
  commitments to which the Purchaser or any Subsidiary is a party that (i) calls
  for the issuance, sale or disposition of any shares of capital stock of the
  Purchaser or any Subsidiary or any securities convertible into, or other
  rights to acquire, any shares of capital stock of the Purchaser or any
  Subsidiary, other than the obligations and commitments of any Subsidiary to
  issue shares of its capital stock to the Purchaser, or (ii) relates to the
  voting of such capital stock, securities or rights.

          4.3.  EGC Common Stock. All of the outstanding shares of EGC Common
  Stock are owned by the Purchaser free and clear of all liens, claims,
  agreements or encumbrances except as set forth on Schedule 4.3 hereto.

          4.4.  Authority; Binding Effect. The Purchaser has the corporate power
  to execute and deliver this Agreement and to perform its obligations
  hereunder. The execution, delivery and performance of this Agreement and the
  consummation of the transactions contemplated hereby have been duly authorized
  by all necessary corporate action on the part of the Purchaser and EGC (except
  on the date hereof, for any corporate action required under the NJBCA in

                                        A-9

  connection with the EGC Merger). Assuming the filings, consents and approvals
  contemplated by this Agreement are obtained or made, neither the Purchaser nor
  EGC is subject to or obligated under any provision of (a) its Articles of
  Incorporation, as amended, or its By-Laws, as amended, (b) except as set forth
  on Schedule 4.4 hereto, any contract, agreement, license, franchise, permit or
  other instrument or (c) any law, statute, ordinance, rule, regulation, order,
  judgment, decree or injunction, which would be breached or violated by the
  Purchaser's execution, delivery and performance of this Agreement or the
  performance of the transactions contemplated hereby other than, with respect
  to the foregoing clauses (b) and (c), such breaches and violations which in
  the aggregate (i) will not have a Material Adverse Effect on the Purchaser and
  its Subsidiaries taken as a whole or will be cured, waived or terminated prior
  to the Effective Time and (ii) will not impair the ability of the Purchaser or
  EGC to perform its obligations hereunder and under the other instruments and
  documents required or contemplated by this Agreement. This Agreement has been
  duly executed and delivered by the Purchaser and constitutes the valid and
  binding agreement of the Purchaser enforceable against it in accordance with
  its terms, except as such enforceability may be limited by applicable laws
  relating to bankruptcy, insolvency, reorganization or affecting creditors'
  rights generally and except to the extent that injunctive or other equitable
  relief is within the discretion of a court.

          4.5.  Consents. Other than in connection or in compliance with (a) the

  order or authorization of, or filing with, any Governmental Entity is required
  to be obtained or made by the Purchaser or any Subsidiary, in connection with
  the execution, delivery or performance by the Purchaser and EGC of this
  Agreement and the instruments and documents required to be executed by them
  pursuant hereto or the consummation by Purchaser and EGC of the transactions
  contemplated hereby, other than those which the failure to obtain or make
  would not have a Material Adverse Effect on the Purchaser and its Subsidiaries
  taken as a whole.

          4.6.  Information Provided. None of the information supplied by the
  Purchaser or any of its Subsidiaries, included or incorporated by reference in
  the Registration Statement or the Proxy Statement will, (a) at the date the
  Registration Statement or any post-effective amendment thereof becomes
  effective, (b) at the date the Proxy Statement is mailed to the shareholders
  of the Company, (c) at the date of the Shareholders Meeting of the Company and
  (d) at all other times subsequent to such effectiveness, mailings or meetings
  up to and including the Effective Time, contain any untrue statement of any
  material fact or omit to state any material fact required to be stated therein
  or necessary in order to make the statements therein, in light of the
  circumstances under which they are made, not misleading.

          4.7.  Absence of Material Adverse Effect. Except as disclosed in the
  Purchaser Reports, or except as contemplated by this Agreement, since

                                       A-10

  September 30, 1992, there has not been any Material Adverse Effect on the
  Purchaser and its Subsidiaries taken as a whole.

          4.8.  SEC Filings; Financial Statements. The Purchaser has heretofore
  delivered to the Company, and made available to the Company the Exhibits to,
  (a) the Purchaser's Annual Reports on Form 10-K for the fiscal years ended
  September 30, 1992, 1991 and 1990, (b) the Purchaser's Quarterly Reports on
  Form 10-Q for the quarters ended March 31, 1993 and December 31, 1992 and (c)
  each prospectus, definitive proxy statement, report and other filing filed by
  the Purchaser with the SEC since September 30, 1992 and prior to the date

  or the Exchange Act. Since September 30, 1992, the Purchaser has filed with
  the SEC all reports and registration statements and all other filings required
  to be filed by it with the SEC pursuant to the Securities Act and the Exchange
  Act. As of their respective dates, the Purchaser Reports did not contain any
  untrue statement of a material fact or omit to state any material fact
  required to be stated therein or necessary in order to make the statements
  therein, in light of the circumstances under which they were made, not
  misleading. The audited and unaudited consolidated financial statements of the
  Purchaser and its consolidated Subsidiaries, included in the Purchaser Reports
  have been prepared in conformity with generally accepted accounting principles
  in all material respects and fairly present, in all material respects, the
  consolidated financial position of the Purchaser and its consolidated
  Subsidiaries as of the dates thereof and the results of their operations and
  their cash flows for each of the periods then ended of the Purchaser and its
  consolidated Subsidiaries subject where appropriate to normal year end
  adjustments.

          4.9.  Litigation. As of the date hereof, except as described in the
  Purchaser Reports, (a) there is no action, suit, proceeding or, to the best
  knowledge of the Purchaser, investigation pending and to the best knowledge of
  the Purchaser, there is no action, suit, proceeding or investigation
  threatened against or affecting the Purchaser or any Subsidiary of the

  Entity, which, individually or in the aggregate, if adversely determined,
  would result in any Material Adverse Effect on the Purchaser and its
  Subsidiaries taken as a whole and (b) neither the Purchaser nor any Subsidiary
  of the Purchaser is subject to any judgment, decree, injunction, rule or order
  of any Governmental Entity or arbitrator which has a Material Adverse Effect

          4.10.  Tax Returns and Audits. Each of the Purchaser and its
  Subsidiaries has duly filed all federal income tax returns required to be
  filed by it and has duly filed all other federal, state, local and foreign Tax
  returns and reports required to be filed by it, except where the failure so to
  file such other federal, state, local and foreign Tax returns and reports
  would not have a Material Adverse Effect on the Purchaser and its Subsidiaries
  taken as a whole, and has duly paid or made adequate provision on its books in
  accordance with generally accepted accounting principles for the payment of
  all Taxes which have been incurred or are due and payable, except where the
  failure so to pay would not have a Material Adverse Effect on the Purchaser
  and its Subsidiaries taken as a whole. As of the date of this Agreement and
  except as disclosed in the Purchaser Reports or Schedule 4.10 hereto, (a)
  there are no pending audits, examinations or proposed audits or examinations
  of any Tax returns filed by the Purchaser or any of its Subsidiaries except
  where the outcome of such audits or examinations would not have a Material
  Adverse Effect on the Purchaser and its Subsidiaries taken as a whole and (b)
  neither the Purchaser nor any of its Subsidiaries have given or been requested

                                       A-11
<PAGE>



  to give waivers or extensions of any statute of limitations relating to the
  payment of Taxes for which the Purchaser or any of its Subsidiaries may be
  liable. As of the date of this Agreement, the consolidated federal income tax
  returns of the Purchaser and its Subsidiaries have been audited by the
  Internal Revenue Service (or the appropriate statute of limitations has
  expired) for all fiscal years through and including September 30, 1986. All
  deficiencies asserted or proposed as a result of any examinations or audits of
  any Tax returns have been paid or adequately provided for on the books of the
  Purchaser or one of its Subsidiaries in accordance with generally accepted
  accounting principles or will not have a Material Adverse Effect on the
  Purchaser and its Subsidiaries taken as a whole.

          4.11.  Certain Agreements. Except as disclosed in the Purchaser
  Reports, as of the date of this Agreement, neither the Purchaser nor any
  Subsidiary, is a party to any oral or written contract, agreement,
  understanding or commitment (except those entered into in the ordinary course
  of business) having a material effect on the Purchaser and its Subsidiaries
  taken as a whole.

          4.12.  PUHCA. The Purchaser is exempt from all provisions of the
  PUHCA, other than Section 9(a)(2) thereof.

          4.13.  Labor Controversies. There are no controversies which would
  have a Material Adverse Effect on the Purchaser and its Subsidiaries, taken as
  a whole, pending or, to the best knowledge of the Purchaser, threatened
  between the Purchaser or any of its Subsidiaries, and any representatives of
  any of their employees and, to the best knowledge of the Purchaser, there are
  no material organizational efforts presently being made involving any of the
  presently unorganized employees of the Purchaser or any of its Subsidiaries.

  Purchaser, complied in all material respects with all laws relating to the
  employment of labor, including any provisions thereof relating to wages,
  hours, collective bargaining and the payment or withholding of social security
  and similar Taxes, and no Person has, to the best knowledge of the Purchaser,

  amount for any arrears of wages or any Taxes or penalties for failure to
  comply with any of the foregoing.

          4.14.  Insurance. The Purchaser and its Subsidiaries, have maintained,
  and are now maintaining with what they reasonably believe are financially
  responsible insurance companies, insurance on their tangible assets and their
  business in such amounts and against such risks and losses as is customary for
  companies engaged in the industries in which the Purchaser and its

          4.16.     Continuity of Business Enterprise; No Plan to Repurchase

          4.17.     Compliance Issues. There are no suits, claims or proceedings

  other authorization necessary to consummate the Merger.

  Person, with respect to this Agreement and the transactions contemplated
  hereby, notwithstanding the delivery or disclosure to the Company or any
  Subsidiary of the Company or any of their respective directors, officers,
  employees, agents or representatives, or any other Person, of any
  documentation or other information by the Purchaser, any Subsidiary of the
  Purchaser, or any of their respective directors, officers, employees, agents

                          REPRESENTATIONS AND WARRANTIES
                                  OF THE COMPANY

          The Company hereby represents and warrants to the Purchaser as
  follows:

          5.1.  Corporate Status. The Company is a corporation duly
  incorporated, validly existing and in good standing under the laws of the
  State of Delaware and has the corporate power and authority to carry on its
  businesses as they are now being conducted. The Company is duly qualified as a
  foreign corporation to do business, and is in good standing, in each
  jurisdiction where the properties owned, leased or operated, or the businesses
  conducted, by it require such qualification, except for such failures to be
  qualified or to be in good standing which when taken together with all such
  other failures of the Company and its Subsidiaries have not had and, so far as
  can reasonably be foreseen at this time, will not have a Material Adverse
  Effect on the Company and its Subsidiaries taken as a whole. The Company has
  previously delivered to the Purchaser complete and correct copies of its
  Articles of Incorporation, as amended, and By-Laws, as amended.

          5.2.  Subsidiaries. Each Subsidiary of the Company is listed on
  Schedule 5.2 hereto. Each Subsidiary of the Company is a corporation duly
  incorporated, validly existing and in good standing under the laws of its
  jurisdiction of incorporation and has the corporate power to carry on its
  businesses as they are now being conducted. Each Subsidiary of the Company is
  duly qualified as a foreign corporation to do business, and is in good
  standing, in each jurisdiction where the properties owned, leased or operated,
  or the business conducted, by it require such qualification, except for such
  failures to be qualified or to be in good standing which when taken together
  with all such other failures of the Company and its Subsidiaries have not had
  and, so far as can reasonably be foreseen at this time, will not have a
  Material Adverse Effect on the Company and its Subsidiaries taken as a whole.
  All of the outstanding shares of the capital stock of each of the Subsidiaries
  of the Company have been validly issued, and are fully paid and nonassessable.
  All of the outstanding shares of common stock of each of the Subsidiaries of

                                       A-13
<PAGE>



  the Company are owned by the Company, directly or indirectly through one or
  more other Subsidiaries, free and clear of all liens, pledges, claims and
  other encumbrances.

          5.3.  Capitalization of the Company. The authorized capital stock of
  the Company consists of 300,000 shares of Company Common Stock. As of June 30,
  1993, (a) 235,857 shares of Company Common Stock were issued and outstanding
  and (b) no shares of Company Common Stock were held in the treasury of the
  Company or owned by any Subsidiary of the Company. As of such date no other
  shares of Company Common Stock were reserved for any other Plan of the Company
  or any of its Subsidiaries or any other shareholder or employee benefit plan
  (including stock option plans). There are no issued or outstanding preferred
  stock, bonds, debentures, notes or other indebtedness or other securities
  having the right to vote on any matters, including the Merger, on which the
  Company's shareholders may vote in connection with the Merger. All outstanding
  shares of Company Common Stock are validly issued, fully paid and
  nonassessable. Except for this Agreement, there are no outstanding
  subscriptions, securities, options, warrants, rights or other agreements,
  understandings or commitments to which the Company or any Subsidiary is a
  party that (i) calls for the issuance, sale or disposition of any shares of
  capital stock of the Company or any Subsidiary or any securities convertible
  into, or other rights to acquire, any shares of capital stock of the Company
  or any Subsidiary, or (ii) relates to the voting of such capital stock,
  securities or rights.

          5.4.  Authority; Binding Effect. The Company has the corporate power
  to execute and deliver this Agreement and, subject to approval of this
  Agreement and the Merger by the shareholders of the Company, to perform its
  obligations hereunder. The execution, delivery and performance of this
  Agreement and the consummation of the transactions contemplated hereby have
  been duly authorized by all necessary corporate action on the part of the
  Company (except, on the date hereof, for the approval of this Agreement by the
  shareholders of the Company). Assuming the filings, consents and approvals
  contemplated by this Agreement are obtained or made, neither the Company nor
  any of its Subsidiaries is subject to or obligated under any provision of (a)
  its Articles of Incorporation (or comparable charter documents) or By-Laws,
  (b) except as set forth on Schedule 5.4 hereto, any contract, agreement,
  license, franchise, permit or other instrument or (c) any law, statute,
  ordinance, rule, regulation, order, judgment, decree or injunction, which
  would be breached or violated by the Company's execution, delivery and
  performance of this Agreement or the performance of the transactions
  contemplated hereby, other than, with respect to the foregoing clauses (b) and
  (c), such breaches and violations which in the aggregate (i) will not have a
  Material Adverse Effect on the Company and its Subsidiaries taken as a whole
  or will be cured, waived or terminated prior to the Effective Time and (ii)
  will not impair the ability of the Company to perform its obligations
  hereunder and under the other instruments and documents required or
  contemplated by this Agreement. This Agreement has been duly executed and
  delivered by the Company and constitutes the valid and binding agreement of
  the Company enforceable against the Company in accordance with its terms,
  except as such enforceability may be limited by applicable laws relating to
  bankruptcy, insolvency, reorganization or affecting creditors' rights
  generally and except to the extent that injunctive or other equitable relief
  is within the discretion of a court.

  HSR Act, (b) the filing with the SEC of the Registration Statement,

  certificates of merger with the Secretary of State of the State of New Jersey

  Company of this Agreement and the instruments and documents required to be
  executed by it pursuant hereto or the consummation by the Company and its
  Subsidiaries of the transactions contemplated hereby, other than those which
  the failure to obtain or make would not have a Material Adverse Effect on the
  Company and the Subsidiaries of the Company taken as a whole.

          5.6.  Financial Statements; Regulatory Filings and Other Disclosure.
  The Company has heretofore delivered to the Purchaser (a) the audited
  consolidated financial statements of the Company and its consolidated
  Subsidiaries at and for each of the years ended September 30, 1992, 1991 and
  1990, (b) the unaudited consolidated financial statements of the Company and
  its consolidated Subsidiaries for the quarters ended December 31, 1992 and
  March 31, 1993, (c) the Company's and each of its Subsidiaries Annual Reports
  to its shareholders for the fiscal years ended September 30, 1992, 1991 and
  1990, (d) copies of all materials distributed to the shareholders of the
  Company since September 30, 1992 and (e) filings by the Company or any of its
  Subsidiaries with state regulatory authorities since September 30, 1989 (items
  (a) through (e) collectively to be known as, the "Company Reports"). As of
  their respective dates, the Company Reports did not contain any untrue
  statement of a material fact or omit to state any material fact required to be
  stated therein or necessary in order to make the statements therein, in light
  of the circumstances under which they were made, not misleading. The audited
  and unaudited consolidated financial statements of the Company and its
  consolidated Subsidiaries included in the Company Reports have been prepared
  in conformity with generally accepted accounting principles, in all material
  respects, and fairly present, in all material respects, the consolidated
  financial position of the Company and its consolidated Subsidiaries as of the
  dates thereof and the results of their operations and their cash flows for
  each of the periods then ended of the Company and its consolidated
  Subsidiaries subject where appropriate to normal year end adjustments.

          5.7.  Absence of Material Adverse Effect. Since September 30, 1992,
  there has not been any Material Adverse Effect on the Company and the
  Subsidiaries of the Company taken as a whole.

          5.8.  Litigation. As of the date hereof, except as set forth on
  Schedule 5.8 hereto, (a) there is no action, suit, proceeding or, to the best
  knowledge of the Company, investigation pending and, to the best knowledge of
  the Company, there is no action, suit, proceeding or investigation threatened
  against or affecting the Company or any of its Subsidiaries, or any of their
  respective properties before any Governmental Entity, which, individually or
  in the aggregate, if adversely determined, would result in any Material
  Adverse Effect on the Company and its Subsidiaries taken as a whole and (b)
  neither the Company nor any of its Subsidiaries is subject to any judgment,
  decree, injunction, rule or order of any Governmental Entity or arbitrator
  which has a Material Adverse Effect on the Company and the Subsidiaries of the

                                       A-15
<PAGE>



  Company taken as a whole.

          5.9.  Employee Benefit Plans. (a) Except as set forth on Schedule 5.9
  hereto, neither the Company nor any of its Subsidiaries, maintains or
  contributes to any Plan, whether formal or informal, and there are no
  agreements, understandings or commitments to create any such Plan or to modify
  or change any existing Plan of the Company or any of its Subsidiaries
  (collectively, "Company Plans"), except as disclosed to Purchaser in writing
  prior to the date hereof. None of the Company Plans is a funded "welfare
  benefit plan" within the meaning of Section 419 of the Code or a "multiple
  employer plan" within the meaning of the Code or ERISA. Except as set forth on
  Schedule 5.9 hereto, the Company does not now, and has not for the five
  calendar years preceding the date hereof contributed to, a "multiemployer
  plan" within the meaning of Section 4001(a)(3) of ERISA.

          (b) The Company has heretofore delivered to the Purchaser true,
  correct and complete copies of (i) all documents which comprise the most
  current version of each of the Company Plans, including any related trust
  agreements, insurance contracts and drafts of proposed amendments, (ii) the
  three most recent Annual Reports (Form 5500 Series) and accompanying schedules
  as filed for each of the Company Plans for which such a report is required,
  (iii) the most current Summary Plan Description, if available (and any summary
  of material modifications) for each Company Plan, (iv) the three most recent
  audited financial statements for each of the Company Plans for which such a
  statement is required or was prepared, (v) the three most recent actuarial
  reports for each of the Company Plans for which such a report is required or
  was prepared and (vi) the most recent determination, if any, issued by the
  Internal Revenue Service with respect to each Company Plan's qualified status
  under Section 401(a) of the Code. Since the date of the documents delivered,
  there has not been any material change in the assets and liabilities of any of
  the Company Plans or any change in their terms and operations which could
  reasonably be expected to affect or alter the tax status or materially affect
  the cost of maintaining such Company Plan.

          (c)  Except as heretofore disclosed to the Purchaser's counsel, the
  Company and its Subsidiaries have each performed and complied in all material
  respects with all of their obligations under and with respect to the Company
  Plans and each of the Company Plans has, at all times, in form and operation
  complied in all material respects with its terms, and, where applicable, the
  requirements of ERISA and the Code, and has not incurred any federal income or
  excise tax liability.

          (d)  Except as heretofore disclosed to the Purchaser's counsel, each
  Company Plan which is an "employee pension benefit plan" (as defined in
  Section 3(2) of ERISA) has received a determination from the Internal Revenue
  Service that it is qualified pursuant to Section 401(a) of the Code and
  nothing has occurred since the date of any such determination to cause the
  loss of such qualification.

          (e)  None of the Company Plans has incurred any "accumulated funding
  deficiency" (as defined in Section 302 of ERISA and Section 412 of the Code),
  and there is no unpaid contribution due prior to the date hereof with respect
  to any such Company Plan that is required to have been made under the terms of
  such Company Plan, Section 412 of the Code or Part 3 of Subtitle B of Title I
  of ERISA.  No "reportable event" (as defined in Section 4043(b) of ERISA) has
  occurred with respect to any Company Plan. The actuarial present value (based
  on the actuarial assumptions used in the most recent actuarial valuation) of
  vested and nonvested "benefit liabilities," (as defined in Section 4001(a)(16)

                                       A-16
<PAGE>



  of ERISA) of each Company Plan that is subject to Title IV of ERISA,
  determined as of the most recent valuation date for each such Company Plan,
  using the actuarial method and assumptions used in the most recent actuarial
  valuation, did not exceed the aggregate fair market value of the assets of
  such Company Plan on such date, and no event has occurred since such date that
  would materially increase or decrease the value of such assets or liabilities.

          (f)  Neither the Company nor any of its Subsidiaries has any
  obligation to provide health or other non-pension related benefits to former
  employees, except as specifically required by law or as set forth on Schedule
  5.9 hereto. The Company has satisfied all requirements imposed upon it to
  provide "continuous coverage" to such employees pursuant to the Consolidated
  Omnibus Budget Reconciliation Act.

          (g)  Neither the Company nor any of its Subsidiaries nor any other
  "disqualified person" or "party in interest" (as defined in Section 4975 of
  the Code and Section 3(14) of ERISA, respectively) has engaged in any
  "prohibited transaction" (as defined in Section 4975 of the Code or Section
  406 of ERISA) with respect to any Company Plan, nor have there been any
  fiduciary violations under ERISA which could subject any such Company Plan (or
  its related trust), or the Company or any of its Subsidiaries (or any officer,
  director, employee, agent or representative thereof) to the penalty or Tax
  under Section 502(i) of ERISA or Sections 4971 and 4975 of the Code.

          (h)  As of the date of this Agreement (i) no filing, application or
  other matter with respect to any of the Company Plans is pending with the
  Internal Revenue Service, Pension Benefit Guaranty Corporation, United States
  Department of Labor or any other Governmental Entity and (ii) there is no
  action, suit or claim pending, other than routine claims for benefits, against
  or in any manner relating to any Company Plan.

          (i)  Neither the Company nor any of its Subsidiaries has incurred any
  liability or taken any action or has any knowledge of any action or event that
  could cause either of them to incur any liability under Section 412 of the
  Code or Title IV of ERISA with respect to any "single-employer plan" (as
  defined in Section 4001(a)(15) of ERISA).  

          (j)  Except as set forth in Section 7.5, neither the execution and
  delivery of this Agreement nor the consummation of the transactions
  contemplated hereby will, (i) entitle any current or former employee of the
  Company or any of its Subsidiaries to severance pay, unemployment compensation
  or any similar payment, (ii) accelerate the time of payment or vesting or
  increase the amount of any compensation due to any such employee or former
  employee, or (iii) directly or indirectly result in any payment made or to be
  made to or on behalf of any Person to constitute a "parachute payment" within
  the meaning of Section 280G of the Code.

          5.10.  Information Provided. None of the information supplied by the
  Company or any of its Subsidiaries included or incorporated by reference in
  the Registration Statement on Form S-4 (or such other form as shall be
  applicable to the registration of Purchaser Common Stock to be issued in
  connection with the Merger) to be filed by the Purchaser with the SEC under
  the Securities Act in order to register thereunder the shares of Purchaser
  Common Stock to be issued in connection with the Merger, including any
  amendments thereof (the "Registration Statement"), or the Proxy Statement
  contained therein to be used by the Company in soliciting proxies of its
  shareholders with respect to the Merger, including any amendments thereof or
  supplements thereto (the "Proxy Statement"), will, (i) at the date the

                                       A-17
<PAGE>



  Registration Statement or any post-effective amendment thereof becomes
  effective, (ii) at the date the Proxy Statement is mailed to the shareholders
  of the Company, (iii) at the date of the Shareholders Meeting of the Company
  and (iv) at all other times subsequent to such effectiveness, mailings or
  meeting up to and including the Effective Time, contain any untrue statement
  of any material fact or omit to state any material fact required to be stated
  therein or necessary in order to make the statements therein, in light of the
  circumstances under which they are made, not misleading. 

          5.11.  Brokers or Finders. No broker, finder or investment banker is
  entitled to any brokerage, finder's fee or other commission or fee in
  connection with the Merger based upon arrangements made by or on behalf of the
  Company, except for a fee payable to Berwind Financial Group, Inc. pursuant to
  an agreement which has been delivered to the Purchaser prior to the date of
  this Agreement.

          5.12.  Tax Returns and Audits. Each of the Company and its
  Subsidiaries has duly filed all federal income tax returns required to be
  filed by it and has duly filed all other federal, state, local and foreign Tax
  returns and reports required to be filed by it, except where the failure so to
  file such other federal, state, local and foreign Tax returns and reports
  would not have a Material Adverse Effect on the Company and its Subsidiaries,
  taken as a whole, and has duly paid or made adequate provision on its books in
  accordance with generally accepted accounting principles for the payment of
  all Taxes which have been incurred or are due and payable, except where the
  failure so to pay would not have a Material Adverse Effect on the Company and
  its Subsidiaries taken as a whole. Except as set forth on Schedule 5.12
  hereto, (a) there are no pending audits, examinations or proposed audits or
  examinations of any Tax returns filed by the Company or any of its
  Subsidiaries except where the outcome of such audits or examinations would not
  have a Material Adverse Effect on the Company and its Subsidiaries taken as a
  whole and (b) neither the Company nor any of its Subsidiaries have given or
  been requested to give waivers or extensions of any statute of limitations
  relating to the payment of Taxes for which the Company or any of its
  Subsidiaries may be liable. As of the date of this Agreement, the consolidated
  federal income tax returns of the Company and its Subsidiaries have been
  audited by the Internal Revenue Service (or the appropriate statute of
  limitations has expired) for all fiscal years through and including September
  30, 1989. All deficiencies asserted or proposed as a result of any
  examinations or audits of any Tax returns have been paid or adequately
  provided for on the books of the Company or one of its Subsidiaries in
  accordance with generally accepted accounting principles or will not have a
  Material Adverse Effect on the Company and its Subsidiaries taken as a whole.
  Except as set forth on Schedule 5.12 hereto, neither the Company nor any of
  its Subsidiaries (i) is a party to any agreement providing for the allocation,
  payment or sharing of Taxes among the Company, its Subsidiaries or any third
  parties, (ii) has any net operating loss carryovers, net capital loss
  carryovers or any other items the use of which, by deduction or credit or
  otherwise, would or may be limited by Section 382 of the Code, (iii) has filed
  any consent to the application of Section 341(f) of the Code with respect to
  any of its property, (iv) has an application pending with respect to any Tax
  requesting permission for a change in accounting method, (v) is required to
  make any adjustments to income pursuant to Section 481 of the Code or (vi)
  owns or leases any real property or otherwise holds any interest in real
  property that would or may subject the parties hereto or the Surviving
  Corporation to a transfer or gains tax as a result of the Merger.

          5.13.  Certain Agreements. Except as disclosed on Schedule 5.13

                                       A-18

  the benefits of which will be calculated on the basis of the transactions
  contemplated hereby, (e) agreement, trust, escrow account or bond to secure or
  provide for the payment of any amounts to any officers, employees or directors

          5.14.  PUHCA. The Company is not subject to the provisions of the
  PUHCA.

          5.15.  Labor Controversies. There are no controversies which would
  have a Material Adverse Effect on the Company and its Subsidiaries taken as a
  whole, pending or, to the best knowledge of the Company, threatened between
  the Company or any of its Subsidiaries and any employees or any
  representatives of any of their employees and, to the best knowledge of the
  Company, there are no material organizational efforts presently being made
  involving any of the presently unorganized employees of the Company or any of
  its Subsidiaries. Each of the Company and its Subsidiaries has, to the best
  knowledge of the Company, complied in all material respects with all laws
  relating to the employment of labor, including any provisions thereof relating
  to wages, hours, collective bargaining and the payment or withholding of
  social security and similar Taxes, and no Person has, to the best knowledge of

  any material amount for any arrears of wages or any Taxes or penalties for
  failure to comply with any of the foregoing.

          5.16.  Insurance. The Company and its Subsidiaries have each
  maintained, and are now maintaining with what they reasonably believe are
  financially responsible insurance companies, insurance on their tangible
  assets and their businesses in such amounts and against such risks and losses
  as is customary for companies engaged in the industries in which the Company
  and its Subsidiaries conduct their businesses. All claims known to the Company
  or any of its Subsidiaries which the Company or such Subsidiary is obligated,

                                       A-19
<PAGE>



  under the terms of any insurance contract or otherwise, to report to one or
  more insurers have been duly and timely reported.

          5.17.  Plant, Property, Equipment and Other Assets.  Schedule 5.17
  hereto lists any real and personal property which has a replacement value of
  $25,000 or more owned or leased by the Company or any of its Subsidiaries.
  Each of the Company and its Subsidiaries has good, clear and marketable or
  insurable title to all the properties and assets listed on Schedule 5.17
  hereto or acquired after the date hereof free and clear of all claims, liens,
  pledges, charges, security interests or other encumbrances of any nature
  whatsoever except (a) statutory liens securing payments not yet due and
  (b) such imperfections or irregularities of title, claims, liens, pledges,
  charges, security interests or other  encumbrances as do not materially affect
  the use of the properties or assets subject thereto or affected thereby or
  otherwise materially impair business operations at such properties, or as do
  not materially impair the marketability thereof. The Company or one of its
  Subsidiaries is the lessee of all leases listed on Schedule 5.17 hereto or
  acquired after the date hereof and is in possession of the properties
  purported to be leased thereunder and each such lease is valid without default
  thereunder by the lessee or, to the best knowledge of the Company, the lessor.

          5.18.  Computer Software. Schedule 5.18 hereto lists all computer
  software programs used by the Company or any of its Subsidiaries other than

  No investigation or review by any Governmental Entity with respect to the
  Company or any of its Subsidiaries is pending or, to the best knowledge of the

  (c) to the best knowledge of the Company, the Company and its Subsidiaries'
  use, generation, processing, production, storage and disposal of hazardous
  substances is and has been in conformity with applicable laws and regulations;

  and personal, and hold all permits, franchises, licenses and other approvals
  or authorizations necessary to carry on the business and operations of each of
  the Company and its Subsidiaries in substantially the same manner as such
  business and operations are carried on currently other than those assets,
  permits, franchises, licenses and other approvals or authorizations the
  failure of which to so own, lease or hold would not have a Material Adverse
  Effect on the Company and its Subsidiaries taken as a whole.

          5.27.     Compliance Issues.  There are no suits, claims or
  proceedings before any Governmental Entity, past or on-going, which taken

  license, permit, order or other authorization necessary to consummate the
  Merger.

          7.14.  Letter of the Company's Accountants. The Company shall cause to
  be delivered to the Purchaser a letter of the Company's independent auditors,
  dated a date within two business days before the date as of which the
  Registration Statement becomes effective and addressed to the Purchaser, in
  form and substance reasonably satisfactory to the Purchaser, to the effect
  that:

          (a)  they are public accountants, independent with respect to the
  Company and its Subsidiaries within the meaning of the Securities Act and the
  Exchange Act and the applicable published rules and regulations thereunder;

          (b)  the financial statements of the Company audited by them and
  included or incorporated by reference in the Registration Statement comply as
  to form in all material respects with the applicable accounting requirements
  of the Securities Act and the Exchange Act and of the published rules and
  regulations thereunder; and

          (c)  at the request of the Company, they have carried out procedures
  to a specified date not more than five business days prior to the date as of
  when the Registration Statement becomes effective, which do not constitute an
  audit in accordance with generally accepted auditing standards, of the
  financial statements of the Company and its consolidated Subsidiaries as
  follows:  (i) read the unaudited financial statements of the Company and its
  consolidated Subsidiaries included or incorporated by reference in the
  Registration Statement, (ii) read the unaudited financial statements of the

  Company and its consolidated Subsidiaries for the period from the date of the
  most recent financial statements included or incorporated by reference in the
  Registration Statement through the date of the latest available interim
  financial statements, (iii) read the minutes of the meetings of shareholders
  and the Board of the Company and any committee thereof, and its consolidated
  Subsidiaries from the date of the most recent financial statements of the
  Company included or incorporated by reference in the Registration Statement to
  such date not more than five business days prior to the date as of when the
  Registration Statement becomes effective and (iv) consulted with certain
  officers of the Company responsible for financial and accounting matters as to
  whether any of the changes or decreases referred to below has occurred, and,
  based on such procedures, nothing has come to their attention which would
  cause them to believe that (A) any unaudited financial statements of the
  Company and its consolidated Subsidiaries included or incorporated by
  reference in the Registration Statement do not comply as to form in all
  material respects with the applicable accounting requirements of the
  Securities Act or the Exchange Act and of the published rules and regulations
  thereunder; (B) such unaudited financial statements are not fairly presented
  in all material respects in conformity with generally accepted accounting
  principles (except as permitted by Form 10-Q of the SEC); (C) as of such date
  not more than five business days prior to the date as of when the Registration
  Statement becomes effective, there was, except as set forth in such letter,
  any (I) change in the capital stock, treasury stock or long-term debt of the
  Company or its Subsidiaries or (II) any decrease in capital in excess of par
  value, retained earnings, consolidated net assets, net current assets or
  investments of the Company in each case as compared with the amounts shown in
  the most recent balance sheet of the Company included or incorporated by
  reference in the Registration Statement or (D) for the period from the date of
  the most recent balance sheet of the Company included or incorporated by
  reference in the Registration Statement to the end of the month immediately
  preceding the date as of when the Registration Statement becomes effective,
  unless the Registration Statement becomes effective within the first ten
  calendar days of a month, in which case, to the end of the next to last
  calendar month prior to the calendar month in which the Registration Statement
  became effective, there were, except as set forth in such letter, any
  decreases, as compared with the corresponding period in the preceding year, in
  consolidated revenues or in the total or per share amounts of income before
  extraordinary items, income before income taxes or net income of the Company.

          7.15.  Reservation of Shares; Listing of Surviving Common Stock. Prior
  to the Closing the Purchaser shall reserve for issuance, out of its authorized
  but unissued Purchaser Common Stock, such number of shares of Purchaser Common
  Stock (which shall become Surviving Common Stock at the Effective Time) as may
  be issuable upon consummation of the Merger. The Purchaser will cause to be
  prepared and submitted to the NYSE a listing application covering the shares
  of Surviving Common Stock issuable in connection with the Merger and will use
  its reasonable best efforts to obtain, prior to the Effective Time, approval
  for the listing of such shares of Surviving Common Stock upon official notice
  of issuance.

          7.16.  Blue Sky Permits. The Purchaser will use its reasonable best
  efforts to obtain, prior to the effective date of the Registration Statement,
  all necessary state securities law or "Blue Sky" permits and approvals
  required to carry out the Merger and the issuance of the Merger Consideration,
  provided that neither the Purchaser nor the Surviving Corporation shall be
  required to qualify as a foreign corporation or to consent to the service of
  process under the laws of any state except Pennsylvania, Maryland, New York
  and North Carolina.

  to the Purchaser, at or prior to the Effective Time, a written agreement, in
  form and substance reasonably satisfactory to the Purchaser, from any Person
  that counsel for the Company may deem to be an "affiliate" of the Company
  within the meaning of such term as used in Rule 145 under the Securities Act,
  to the effect that no disposition of Surviving Common Stock received in the
  Merger will be made by such Persons except within the limits and in accordance
  with the applicable provisions of said Rule 145, as amended from time to time,
  or except in a transaction which, in the opinion of counsel reasonably
  satisfactory to the Surviving Corporation, is exempt from registration under
  the Securities Act.

          7.18.     Shareholder Agreements. The Company will cause to be
  delivered to the Purchaser, on or prior to the date of filing of the
  Registration Statement with the SEC, a written agreement, in form and
  substance reasonably satisfactory to the Purchaser, from shareholders of the
  Company who, immediately prior to the date of filing of the Registration
  Statement with the SEC, hold in the aggregate not less than 50% of the
  outstanding shares of Company Common Stock, pursuant to which such
  shareholders shall agree for a period of one year from the Closing Date not to
  sell, transfer or otherwise voluntarily dispose of an aggregate number of
  shares of Surviving Common Stock received by such shareholders in the Merger
  which have a value (determined using the Average Market Price) equal to not
  less than 50% of the aggregate Merger Consideration (assuming for purposes of
  this Section that there will be no Dissenting Shareholders).

  or kind of shares, securities, cash, property and/or rights to be received in
  exchange for or on conversion of all or any of the shares of the Company
  Common Stock upon consummation of the Merger, (b) any term of the articles of

  of, or estoppel with respect to, any subsequent or other failure of any party
  to perform its obligation under this Agreement.

  January 10, 1994



  Board of Directors
  Pennsylvania & Southern

  Ladies and Gentlemen:

     You have requested the opinion of Berwind Financial Group, Inc. ("Berwind")
  as to the fairness, from a financial point of view, to the shareholders of
  Pennsylvania & Southern Gas Company ("PSGS") of the financial terms of the
  proposed transaction whereby PSGS will be merged (the "Merger") with and into
  NUI Corporation ("NUI"). The terms of the Merger are set forth in the
  Agreement and Plan of Merger, dated July 27, 1993, by and between NUI and PSGS
  (the "Merger Agreement") and provide that each outstanding share of PSGS
  Common Stock, $1.25 par value per share, other than shares owned by dissenting
  stockholders, will be converted into 2.4 to 3.0 shares of NUI Common Stock, no
  par value ("NUI Common Stock"), subject to adjustment based upon the
  arithmetic average of the daily closing price per share of NUI Common Stock
  for the twenty trading days immediately prior to consummation of the Merger as
  detailed in the Merger Agreement.

     Berwind, as part of its investment banking business, regularly is engaged
  in the valuation of assets, securities and companies in various types of asset
  and security transactions, including the valuation of assets, securities and
  companies in mergers, acquisitions, divestitures and leveraged buyouts and in
  the determination of adequate consideration in such transactions.

     In accordance with the terms of our engagement letter dated May 3, 1993, we
  submit this letter which sets forth our opinion and summarizes the procedures
  used in arriving at that opinion.

  A. Documentation and Information Examined

     As background for our analysis of the proposed transaction, we reviewed the
  history, current operations and future prospects of PSGS with certain of PSGS'
  management, in addition to reviewing the history, current operations and
  future prospects of NUI with certain members of NUI management. Our financial
  analysis is based upon, but not limited to, the review of PSGS audited
  financial statements, internal worksheets, and internal operating reports.
  Specifically, the following were among the documents and information we
  examined during the course of our analysis:

     1.   PSGS and NUI audited financial statements for the fiscal years
          1988 through 1993 and quarterly reports to shareholders dated
          December 31, 1992, March 31, 1993, and June 30, 1993.

     2.   PSGS and NUI managements' projected financial summaries for

                                        B-1

          the fiscal years ended September 30, 1994 through 1996.

     3.   PSGS and NUI budgets for the fiscal year ended September 30,
          1993.

     4.   Schedules of receivables aging, payables aging and bad debt
          experience for PSGS and NUI.

     5.   Schedules of PSGS and NUI's largest customers and suppliers.

     6.   PSGS and NUI organization charts.

     7.   PSGS and NUI Schedule of pending litigation.

     8.   Historical and present stock market performances of NUI and
          PSGS.

  B. Persons Interviewed

     During the course of our analysis, we conducted meetings and interviews
  with persons who, in our judgement, were capable of providing us with
  information necessary to complete the assignment. These interviews and
  meetings included, but were not limited to, Lyle Motley, Jr., and Bernard
  Smith of PSGS and Frank Bahniuk, Glyn Hazeldon, Robert P. Kenney, Jack Langer,
  Rand W. Smith, and Richard Wall of NUI and/or its subsidiaries.

  C. Facilities Visited

     As part of the development of information and our opinion, we visited PSGS
  facilities located in Sayre, Pennsylvania as well as NUI's facilities in
  Bedminster, New Jersey and its subsidiaries in Elizabethtown, New Jersey and
  Hialeah, Florida.

  D. Factors Considered

     In arriving at our opinion, we considered the following factors, among
  others, which we deemed relevant.

     1.   The history and management of PSGS and NUI.

     2.   The nature of and businesses operated by PSGS and NUI and the
          future prospects for each.

     3.   The historical and current operating results of PSGS and NUI
          and the factors affecting these results.

     4.   The historical and current financial conditions of PSGS and
          NUI.

     5.   The historical and current book value of PSGS and NUI's assets
          and liabilities.

     6.   Projected financial, including cashflow, results of PSGS and

                                        B-2

          NUI prepared by their respective managements.

     7.   Available information on "comparable" publicly traded
          companies which were not, in our opinion, directly comparable.

     8.   Available information on so called "comparable" merger and
          acquisition transactions which were not, in our opinion,
          directly comparable.

     9.   Conditions in the general economy and the industries in which
          PSGS and NUI operate.

     10.  The financial terms and conditions of the proposed
          transaction.

     In addition, Berwind conducted other such financial analyses, studies and
  investigations as we deemed appropriate.

  E. Access to Information and Personnel

     During our analysis, we received access to all materials and personnel
  which we deemed necessary and adequate for the purpose of formulating the
  opinion expressed in this letter, and no limitations were placed upon our
  investigations.

  F. Assumptions and Limitations

     Our opinion is subject to the following assumptions and limitations.

     1.   We express no opinion as to the tax consequences, if any, to
          PSGS, NUI and their shareholders.

     2.   We have made no independent verification of the financial and
          operating data contained in PSGS or NUI's internal and audited
          financial statements and other data provided to us by PSGS and
          NUI management, and have accepted the information as
          presented. In addition, since Berwind is not qualified as an
          expert in detecting the presence of potentially hazardous
          materials, we have relied upon PSGS and NUI managements'
          representations that reserves have been established for all
          known and quantifiable environmental problems. Accordingly, as
          of the date of this opinion, since any impact relating to
          additional environmental problems has not been determined, we
          have not considered the potential impact in our analysis. Our
          analysis assumed current reserves adequately protect
          shareholders from the impact of known and quantifiable
          environmental problems.

     3.   Our opinion is based upon market, economic, financial and
          other conditions as they exist and can be evaluated as of the
          date of this letter and speaks to no other time period.

     4.   We assume that the proposed transaction is, in all respects,

                                        B-3

          lawful under applicable corporate law.

     5.   We have assumed and relied upon the accuracy and completeness
          of the information provided to Berwind by PSGS and NUI
          management without independent investigation. With respect to
          financial projections, we have assumed, for purposes of our
          opinion, that they have been reasonably prepared by PSGS' and
          NUI's managements on bases reflecting the best currently
          available estimates and judgements of the future financial
          performance of the companies.

  G. Conclusion

     In preparing our opinion, we have relied upon the completeness and accuracy
  of the information and data furnished to us by PSGS and NUI as of the date
  hereof. We have not independently verified such data nor data obtained from
  regularly published sources. In addition, we have not considered the impact of
  environmental problems, except as noted in Section F. In the event that an
  additional environmental problem arises, or the known environmental problems
  result in costs in excess of current estimates, this opinion may require
  modification depending upon the magnitude of such problem.

     We are not aware of any present or contemplated relationship between
  Berwind and PSGS that, in our opinion, would affect our ability to render a
  fair and independent opinion in this matter. Our opinion pertains only to the
  financial consideration of the proposed transaction and does not constitute a
  recommendation to PSGS shareholders as to how such shareholders should vote on
  the Merger Agreement.

     Based upon the foregoing analysis and review, other matters we considered
  relevant, our general knowledge and experience in the valuation of companies,
  and subject to the assumptions and limitations detailed above, we believe that
  the proposed transaction between PSGS and NUI is fair from a financial point
  of view to PSGS as of the date of this letter.

                              Respectfully submitted,


                              Berwind Financial Group, Inc.

  Section 262. Appraisal Rights

               (a)  Any stockholder of a corporation of this State who holds
  shares of stock on the date of the making of a demand pursuant to the
  provisions of subsection (d) of this section with respect to such shares, who
  continuously holds such shares through the effective date of the merger or
  consolidation, who has otherwise complied with the provisions of subsection
  (d) of this Section and who has neither voted in favor of the merger or
  consolidation nor consented thereto in writing pursuant to Section 228 of this
  Chapter shall be entitled to an appraisal by the Court of Chancery of the fair
  value of his shares of stock under the circumstances described in subsections
  (b) and (c) of this section. As used in this section, the word "stockholder"
  means a holder of record of stock in a stock corporation and also a member of
  record of a non-stock corporation; the words "stock" and "share" mean and
  include what is ordinarily meant by those words and also membership or
  membership interest of a member of a non-stock corporation. 

               (b)  Appraisal rights shall be available for the shares of any
  class or series of stock of a constituent corporation in a merger or
  consolidation to be effected pursuant to sections 251, 252, 254, 257, 258, 263
  and 264 of this Chapter; 

                    (1)  Provided, however, that no appraisal rights under this
  section shall be available for the shares of any class or series of stock
  which, at the record date fixed to determine the stockholders entitled to
  receive notice of and to vote at the meeting of stockholders to act upon the
  agreement of merger or consolidation, were either (i) listed on a national
  securities exchange or designated as a national market system security on an
  interdealer quotation system by the National Association of Securities
  Dealers, Inc. or (ii) held of record by more than 2,000 stockholders; and
  further provided that no appraisal rights shall be available for any shares of
  stock of the constituent corporation surviving a merger if the merger did not
  require for its approval the vote of the stockholders of the surviving
  corporation as provided in subsection (f) of section 251 of this Chapter. 

                    (2)  Notwithstanding paragraph (1) of this subsection,
  appraisal rights under this section shall be available for the shares of any
  class or series of stock of a constituent corporation if the holders thereof
  are required by the terms of an agreement of merger or consolidation pursuant
  to sections 251, 252, 254, 257, 258, 263 and 264 of this Chapter to accept for
  such stock anything except:  (a) Shares of stock of the corporation surviving
  or resulting from such merger or consolidation; (b) Shares of stock of any
  other corporation which at the effective date of the merger or consolidation
  will be either listed on a national securities exchange or designated as a
  national market system security on an interdealer quotation system by the
  National Association of Securities Dealers, Inc. or held of record by more
  than 2,000 stockholders; (c) Cash in lieu of fractional shares of the
  corporations described in the foregoing subparagraphs a. and b. of this
  paragraph; or (d) Any combination of the shares of stock and cash in lieu of
  fractional shares described in the foregoing subparagraphs a., b. and c. of
  this paragraph. 

                    (3)  In the event all of the stock of a subsidiary Delaware
  corporation party to a merger effected under Section 253 of this title is not
  owned by the parent corporation immediately prior to the merger, appraisal

                                        C-1
<PAGE>



  rights shall be available for the shares of the subsidiary Delaware
  corporation. 

               (c)  Any corporation may provide in its certificate of
  incorporation that appraisal rights under this section shall be available for
  the shares of any class or series of its stock as a result of an amendment to
  its certificate of incorporation, any merger or consolidation in which the
  corporation is a constituent corporation or the sale of all or substantially
  all of the assets of the corporation. If the certificate of incorporation
  contains such a provision, the procedures of this section, including those set
  forth in subsections (d) and (e) of this section, shall apply as nearly as is
  practicable. 

               (d)  Appraisal rights shall be perfected as follows:  
                    (1)  If a proposed merger or consolidation for which
  appraisal rights are provided under this section is to be submitted for
  approval at a meeting of stockholders, the corporation, not less than 20 days
  prior to the meeting, shall notify each of its stockholders who was such on
  the record date for such meeting with respect to shares for which appraisal
  rights are available pursuant to subsections (b) or (c) hereof that appraisal
  rights are available for any or all of the shares of the constituent
  corporations, and shall include in such notice a copy of this section. Each
  stockholder electing to demand the appraisal of his shares shall deliver to
  the corporation, before the taking of the vote on the merger or consolidation,
  a written demand for appraisal of his shares. Such demand will be sufficient
  if it reasonably informs the corporation of the identity of the stockholder
  and that the stockholder intends thereby to demand the appraisal of his
  shares. A proxy or vote against the merger or consolidation shall not
  constitute such a demand. A stockholder electing to take such action must do
  so by a separate written demand as herein provided. Within 10 days after the
  effective date of such merger or consolidation, the surviving or resulting
  corporation shall notify each stockholder of each constituent corporation who
  has complied with the provisions of this subsection and has not voted in favor
  of or consented to the merger or consolidation of the date that the merger of
  consolidation has become effective; or

                    (2)  If the merger or consolidation was approved pursuant to
  section 228 or section 253 of this title, the surviving or resulting
  corporation, either before the effective date of the merger or consolidation
  or within 10 days thereafter, shall notify each of the stockholders entitled
  to appraisal rights of the effective date of the merger or consolidation and
  that appraisal rights are available for any or all of the shares of the
  constituent corporation, and shall include in such notice a copy of this
  section. The notice shall be sent by certified or registered mail, return
  receipt requested, addressed to the stockholder at his address as it appears
  on the records of the corporation. Any stockholder entitled to appraisal
  rights may, within 20 days after the date of mailing of the notice, demand in
  writing from the surviving or resulting corporation the appraisal of his
  shares. Such demand will be sufficient if it reasonably informs the
  corporation of the identity of the stockholder and that the stockholder
  intends thereby to demand the appraisal of his shares. 

               (e)  Within 120 days after the effective date of the merger or
  consolidation, the surviving or resulting corporation or any stockholder who
  has complied with the provisions of subsections (a) and (d) hereof and who is
  otherwise entitled to appraisal rights,  may file a petition in the Court of
  Chancery demanding a determination of the value of the stock of all such
  stockholders. Notwithstanding the foregoing, at any time within 60 days after

                                        C-2
<PAGE>



  the effective date of the merger or  consolidation, any stockholder shall have
  the right to withdraw his demand for appraisal and to accept the terms offered
  upon the merger or consolidation. Within 120 days after the effective date of
  the merger or consolidation, any stockholder who has complied with the
  requirements of subsection (a) and (d) hereof, upon written request, shall be
  entitled to receive from the corporation surviving the merger or resulting
  from the consolidation a statement setting forth the aggregate number of
  shares not voted in favor of the merger or consolidation and with respect to
  which demands for appraisal have been received and the aggregate number of
  holders of such share. Such written statement shall be mailed to the
  stockholder within 10 days after his written request for such a statement is
  received by the surviving or resulting corporation or within 10 days after
  expiration of the period for delivery of demands for appraisal under
  subsection (d) hereof, whichever is later. 

               (f)  Upon the filing of any such petition by a stockholder,
  service of a copy thereof shall be made upon the surviving or resulting
  corporation, which shall within 20 days after such service file in the office
  of the Register in Chancery in which the petition was filed a duly verified
  list containing the names and addresses of all stockholders who have demanded
  payment of their shares and with whom agreements as to the value of their
  shares have not been reached by the surviving or resulting corporation. If the
  petition shall be filed by the surviving or resulting corporation, the
  petition shall be accompanied by such a duly verified list. The Register in
  Chancery, if so ordered by the Court, shall give notice of the time and place
  fixed for the hearing of such petition by registered or certified mail to the
  surviving or resulting corporation and to the stockholders shown on the list
  at the addresses therein stated. Such notice shall also be given by 1 or more
  publications at least 1 week before the day of the hearing, in a newspaper of
  general circulation published in the City of Wilmington, Delaware or such
  publication as the Court deems advisable. The forms of the notices by mail and
  by publication shall be approved by the Court, and the costs thereof shall be
  borne by the surviving or resulting corporation. 
               (g)  At the hearing on such petition, the Court shall determine
  the stockholders who have complied with this section and who have become
  entitled to appraisal rights. The Court may require the stockholders who have
  demanded an appraisal for their shares and who hold stock represented by
  certificates to submit their certificates of stock to the Register in Chancery
  for notation thereon of the pendency of the appraisal proceedings; and if any
  stockholder fails to comply with such direction, the Court may dismiss the
  proceedings as to such stockholder. 

               (h)  After determining the stockholders entitled to an appraisal,
  the Court shall appraise the shares, determining their fair value exclusive of
  any element of value arising from the accomplishment or expectation of the
  merger or consolidation, together with a fair rate of interest, if any, to be
  paid upon the amount determined to be the fair value. In determining such fair
  value, the Court shall take into account all relevant factors. In determining
  the fair rate of interest, the Court may consider all relevant factors,
  including the rate of interest which the surviving or resulting corporation
  would have had to pay to borrow money during the pendency of the proceeding.
  Upon  application by the surviving or resulting corporation or by any
  stockholder entitled to participate in the appraisal proceeding, the Court
  may, in its discretion, permit discovery or other pretrial proceedings and may
  proceed to trial upon the appraisal prior to the final determination of the
  stockholder entitled to an appraisal. Any stockholder whose name appears on
  the list filed by the surviving or resulting corporation pursuant to
  subsection (f) of this section and who has submitted his certificates of stock

                                        C-3
<PAGE>



  to the Register in Chancery, if such is required, may participate fully in all
  proceedings until it is finally determined that he is not entitled to
  appraisal rights under this section. 
               (i)  The Court shall direct the payment of the fair value of the
  shares, together with interest, if any, by the surviving or resulting
  corporation to the stockholders entitled thereto. Interest may be simple or
  compound, as the Court may direct. Payment shall be so made to each such
  stockholder, in the case of holders of uncertificated stock forthwith, and in
  the case of holders of shares represented by certificates upon the surrender
  to the corporation of the certificates representing such stock. The Court's
  decree may be enforced as other decrees in the Court of Chancery may be
  enforced, whether such surviving or resulting corporation be a corporation of
  this State or of any other state. 

               (j)  The costs of the proceeding may be determined by the Court
  and taxed upon the parties as the Court equitable in the circumstances. Upon
  application of a stockholder, the Court may order all or a portion of the
  expenses incurred by any stockholder in connection with the appraisal
  proceeding, including, without limitation, reasonable attorneys' fees and the
  fees and expenses of experts, to be charged pro rata against the value of all
  of the shares entitled to an appraisal. 
               (k)  From and after the effective date of the merger or
  consolidation, no stockholder who has demanded his appraisal rights as
  provided in subsection (d) of this section shall be entitled to vote such
  stock for any purpose or to receive payment of dividends or other
  distributions on the stock (except dividends or other distributions payable to
  stockholders of record at a date which is prior to the effective date of the
  merger or consolidation); provided, however, that if no petition for an
  appraisal shall be filed within the time provided in subsection (e) of this
  section, or if such stockholder shall deliver to the surviving or resulting
  corporation a written withdrawal of his demand for an appraisal and an
  acceptance of the merger or consolidation, either within 60 days after the
  effective date of the merger or consolidation as provided in subsection (e) of
  this section or thereafter with the written approval of the corporation, then
  the right of such stockholder to an appraisal shall cease. Notwithstanding the
  foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed
  as to any stockholder without the approval of the Court, and such approval may
  be conditioned upon such terms as the Court deems just. 

               (l)  The shares of the surviving or resulting corporation to
  which the shares of such objecting stockholders would have been converted had
  they assented to the merger or consolidation shall have the status of
  authorized and unissued shares of the surviving or resulting corporation.
  (Last amended by Chapter 61, Laws of 1933, effective 7-1-93.)
