                    (b)  Contributions.  Except as set forth in Section
                         -------------                          -------

                         -----------------
          Benefit Plan and any other plan, fund or program maintained or
          contributed to during the past ten (10) years by UPEN or any UPEN
          Subsidiary or any member of a controlled group (as defined in

                         (i)  no such plan has been terminated so as to
               subject, directly or indirectly, UPEN or any UPEN Subsidiary
               to any liability, contingent or otherwise, or the imposition

                         (iii)  to the knowledge of UPEN, no condition or
               event exists or is expected to occur that could subject,

               liability, contingent or otherwise, or the imposition of any
               lien under Title IV of ERISA on the assets of UPEN or any
               UPEN Subsidiary, whether to the PBGC or to any other person
               or otherwise;

                         (iv)  if any such plan were to be terminated, no
               assets of UPEN or any UPEN Subsidiary would be subject,
               directly or indirectly, to any liability, contingent or
               otherwise, or the imposition of any lien under Title IV of
               ERISA other than for the payment of benefits in the ordinary
               course of business;

                         (v)  no "reportable event" (as defined in Section
               4043 of ERISA other than a reportable event with respect to
               which the 30-day notice to the PBGC has been waived) has

               "accumulated funding deficiency" (as defined in Section 302
               of ERISA and Section 412 of the Code), whether or not such
               deficiency has been waived. 

                    (e)  Qualification; Compliance.  Except as set forth in
                         -------------------------
          Section 5.10(e) of the UPEN Disclosure Schedule, each of the UPEN
          ---------------
          Benefit Plans intended to be "qualified" within the meaning of
                                        ---------
          Section 401(a) of the Code has been determined by the IRS to be
          --------------
          so qualified as to form, and, to the knowledge of UPEN, no
          circumstances exist that are reasonably expected by UPEN to
          result in the revocation of any such determination.  To the
          knowledge of UPEN, UPEN is in compliance in all respects with,
          and each of the UPEN Benefit Plans is and has been operated in
          accordance with the term of such plan and in all respects in
          compliance with, all applicable laws, rules and regulations
          governing each such plan, including, without limitation, ERISA
          and the Code, except for any violations that, in the aggregate do
          not, and insofar as reasonably can be foreseen, would not, give
          rise to an UPEN Material Adverse Effect.  To the knowledge of
          UPEN, each UPEN Benefit Plan (and where applicable, its related
          trust) intended to provide for the deferral of income, the
          reduction of salary or other compensation, or to afford other
          income tax benefits, complies in all material respects with the
          requirements of the applicable provisions of the Code or other
          laws, rules and regulations required to provide such income tax
          benefits.

                    (f)  Liabilities.  With respect to the UPEN Benefit
                         -----------
          Plans, individually and in the aggregate, no event has occurred,
          and, to the knowledge of UPEN, there does not now exist any
          condition or set of circumstances that could subject UPEN or any
          of the UPEN Subsidiaries to any liability arising under the Code,
          ERISA or any other applicable law (including, without limitation,
          any liability of any kind whatsoever, whether direct or indirect,
          contingent, inchoate or otherwise, to any such plan or the PBGC),
          or under any indemnity agreement to which UPEN is subject, which
          liability, excluding liability for PBGC premiums, benefit claims
          and funding obligations payable in the ordinary course, has, or
          insofar as reasonably can be foreseen, would have, an UPEN
          Material Adverse Effect.

                    (g)  Welfare Plans.  Except as set forth in Section
                         -------------                          -------

          -------
          Benefit Plans that are "welfare plans" within the meaning of
                                  -------------
          Section 3(1) of ERISA, provides for any benefits (and neither
          -----------
          UPEN nor any UPEN Subsidiary has any obligation to provide
          benefits) payable to or on behalf of any employee or director
          after termination of employment or service, as the case may be,
          other than elective continuation coverage required to be provided
          under Section 4980B of the Code or Part 6 of Title I of ERISA or
                -------------
          coverage which expires at the end of the calendar month following
          such event, and (ii) with respect to each UPEN Benefit Plan (or
          other plan, contract or arrangement under which UPEN or any UPEN
          Subsidiary has an obligation to provide benefits) identified in
          Section 5.10(g) of the UPEN Disclosure Schedule as providing
          ---------------
          welfare benefits payable to or on behalf of any employee or
          director after termination of employment or service, UPEN or the
          applicable UPEN Subsidiary may at any time amend, modify or
          terminate such benefits.

                         ------------------------

          agreement to which UPEN or any of the UPEN Subsidiaries is a
          party or under which UPEN or any of the UPEN Subsidiaries has
          obligations and, with respect to each UPEN Benefit Plan, where

               alone or upon the occurrence of any additional or further
               acts or events) result in any

          Statement.  The parties will prepare and file with the SEC as
          ---------
          soon as reasonably practicable after the date hereof the
          Registration Statement and the Proxy Statement (together, the
          "Proxy/Registration Statement").  The parties hereto shall each
           ----------------------------
          use reasonable efforts to cause the Registration Statement to be
          declared effective under the Securities Act as promptly as
          practicable after such filing.  Each party hereto shall also take
          such action as may reasonably be required to cause the shares of
          WPS Common Stock issuable in connection with the Merger to be
          registered (or to obtain an exemption from registration) under
          applicable state "blue sky" or securities laws; provided,
                                                          --------
          however, that no party shall be required to register or qualify
          -------
          as a foreign corporation or to take other action which would
          subject it to service of process in any jurisdiction where it
          will not be, following the Merger, so subject.  Each of the
          parties hereto shall furnish all information concerning itself
          which is required or customary for inclusion in the
          Proxy/Registration Statement.  The parties shall use reasonable
          efforts to cause the shares of WPS Common Stock issuable in the
          Merger to be approved for listing on the NYSE subject only to
          official notice of issuance.  The information provided by any
          party hereto for use in the Proxy/Registration Statement shall be
          true and correct in all material respects without omission of any
          material fact which is required to make such information not
          false or misleading.  No representation, covenant or agreement is
          made by any party hereto with respect to information supplied by
          any other party for inclusion in the Proxy/Registration
          Statement.

          cause to be filed with the Federal Trade Commission and the
          Department of Justice any notifications required to be filed by
          itself or its respective "ultimate parent" company under the

          Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended
          (the "HSR Act"), and the rules and regulations promulgated
                -------
          thereunder with respect to the transactions contemplated hereby. 
          Such parties will use all commercially reasonable efforts to make
          such filings as promptly as reasonably practicable after the date
          hereof, and to respond promptly to any requests for additional
          information made by either of such agencies.

                    (b)  Other Regulatory Approvals.  Each party hereto
                         --------------------------

          promptly all necessary documentation, to effect all necessary
          applications, notices, petitions, filings and other documents,
          and to use all commercially reasonable efforts to obtain all
          necessary permits, consents, approvals and authorizations of all
          Governmental Authorities necessary or advisable to consummate the
          Merger, including, without limitation, the WPS Required Statutory
          Approvals and the UPEN Required Statutory Approvals.  Each party
          shall have the right to review and approve in advance all of the
          information concerning such party which appears in any filing
          made in connection with the transactions contemplated by this
          Agreement and the Merger.  WPS shall allow UPEN and its counsel a
          meaningful opportunity to consult with WPS with respect to, and
          to participate with WPS in, the efforts to obtain all necessary
          approvals from Governmental Authorities in connection with the
          transactions contemplated by this Agreement and the Merger
          (including, but not limited to, the FERC), it being understood
          that all positions taken in the filings with such Governmental
          Authorities shall be consistent with one another and consistent
          with this Agreement.

               and state law and with its Articles of Incorporation and
               By-laws, 

                         (iii)  subject to the fiduciary duties of its
               Board of Directors, recommend to its shareholders the
               approval of the Merger, this Agreement and the transactions
               contemplated hereby, and

               the foregoing matters.

                    (b)  Meeting Date.  The UPEN Special Meeting shall be

          provided by an existing right of indemnification or other
          agreement or policy, from and after the Effective Time, WPS

          has been at any time prior to the date hereof, or who becomes
          prior to the Effective Time, an officer, director or employee of

                         (i)  all losses, expenses (including reasonable
               attorney's fees and expenses), claims, damages or
               liabilities or, subject to the proviso of the next
               succeeding sentence, amounts paid in settlement, arising out
               of actions or omissions occurring at or prior to the
               Effective Time (and whether asserted or claimed prior to, at
               or after the Effective Time) that are, in whole or in part,
               based on or arising out of the fact that such person is or
               was a director, officer or employee of UPEN or of any UPEN
               Subsidiary (the "Indemnified Liabilities"), and

                         (ii)  all Indemnified Liabilities to the extent
               that they are based on or arise out of or pertain to the
               transactions contemplated by this Agreement.

          In the event of any such loss, expense, claim, damage or
          liability (whether or not arising before the Effective Time), 

                              (A) WPS shall pay the reasonable fees and
                    expenses of counsel selected by the Indemnified
                    Parties, which counsel shall be reasonably satisfactory
                    to WPS, promptly after statements therefor are received
                    and otherwise advance to such Indemnified Party upon
                    request reimbursement of documented expenses reasonably
                    incurred, 

                              (B)  WPS will cooperate in the defense of any
                    such matter, and

                              (C)  any determination required to be made
                    with respect to whether an Indemnified Party's conduct
                    complies with the standards set forth under Sections
                                                                --------

                    --------         --------
                    Articles of Incorporation or By-laws of WPS (as the
                    same shall be amended from time to time) shall be made
                    by independent counsel mutually acceptable to WPS and
                    the Indemnified Party; provided, however, that WPS
                                           --------  -------
                    shall not be liable for any settlement effected without
                    its written consent (which consent shall not be
                    unreasonably withheld).

                    The Indemnified Parties as a group may retain only one
          law firm with respect to each related matter except to the extent
          that there is, in the sole opinion of counsel to an Indemnified
          Party, under applicable standards of professional conduct, a
          conflict on any significant issue between positions of such
          Indemnified Party and any other Indemnified Party or Indemnified
          Parties.

                    (b)  Insurance.  For a period of six years after the
                         ---------
          Effective Time, WPS shall (i) cause to be maintained in effect
          policies of directors' and officers' liability insurance
          maintained by UPEN for the benefit of those persons who are
          currently covered by such policies on terms no less favorable
          than the terms of such current insurance coverage or (ii) obtain
          new policies of such insurance with respect to such obligations
          at least as favorable as the most favorable coverage offered by
          policies currently maintained by UPEN and WPS; provided, however,
                                                         --------  -------
          that WPS shall not be required to expend in any year an amount in
          excess of 250% of the annual aggregate premiums currently paid by
          UPEN for such insurance; and provided, further, that if the
                                       --------  -------
          annual premiums of such insurance coverage exceed such amount,
          WPS shall be obligated to obtain a policy with the best coverage
          available, in the reasonable judgment of the Board of Directors
          of WPS, for a cost not exceeding such amount.

                    (c)  Successors.  In the event WPS or any of its
                         ----------
          successors or assigns (i) consolidates with or merges into any
          other person and shall not be the continuing or surviving
          corporation or entity of such consolidation or merger, or
          (ii) transfers all or substantially all of its properties and
          assets to any person, then and in either such case, proper
          provisions shall be made so that the successors and assigns of
          WPS shall assume the obligations set forth in this Section 7.5.
                                                             -----------

                    (d)  Survival of Indemnification.  To the fullest
                         ---------------------------
          extent permitted by law, from and after the Effective Time, all
          rights to indemnification as of the date hereof in favor of the
          employees, agents, directors and officers of UPEN and the UPEN
          Subsidiaries with respect to their activities as such prior to
          the Effective Time, as provided in their respective articles of
          incorporation and by-laws in effect on the date thereof, or
          otherwise in effect on the date hereof, shall survive the Merger
          and shall continue in full force and effect for a period of not
          less than six years from the Effective Time.

                    (e)  Benefit.  The provisions of this Section 7.5 are
                         -------                          -----------
          intended to be for the benefit of, and shall be enforceable by,
          each Indemnified Party, his or her heirs and his or her
          representatives.

                                   --------------------
          hereof, 

                    (a)  UPEN has delivered to WPS a UPEN Disclosure
          Schedule, accompanied by a certificate signed by the chief
          financial officer of UPEN stating the UPEN Disclosure Schedule is

          Schedule, accompanied by a certificate signed by the chief
          financial officer of WPS stating the WPS Disclosure Schedule is
          being delivered pursuant to this Section 7.6(b).
                                           --------------

                    (c)  The WPS Disclosure Schedule and the UPEN
          Disclosure Schedule are collectively referred to herein as the
          "Disclosure Schedules."
           --------------------

                    (d)  The Disclosure Schedules constitute an integral
          part of this Agreement and modify the respective representations,
          warranties, covenants or agreements of the parties hereto
          contained herein to the extent that such representations,
          warranties, covenants or agreements expressly refer to the
          Disclosure Schedules.  Anything to the contrary contained herein
          or in the Disclosure Schedules notwithstanding, any and all
          statements, representations, warranties or disclosures set forth
          in the Disclosure Schedules shall be deemed to have been made on
          and as of the date hereof.

                    Section 7.7    Public Announcements.  Subject to each
                                   --------------------
          party's disclosure obligations imposed by law, WPS and UPEN will
          cooperate with each other in the development and distribution of
          all news releases and other public information disclosures with
          respect to this Agreement or any of the transactions contemplated
          hereby and shall not issue any public announcement or statement
          with respect hereto or thereto without the consent of the other
          party (which consent shall not be unreasonably withheld).

                    Section 7.8    Rule 145 Affiliates.  Within 30 days
                                   -------------------
          before the Closing Date, UPEN shall identify in a letter to WPS
          all persons who are, and to such person's knowledge who will be
          at the Closing Date, "affiliates" of UPEN, as such term is used
                                ----------
          in Rule 145 under the Securities Act (or otherwise under
          applicable SEC accounting releases with respect to
          pooling-of-interests accounting treatment).  UPEN shall use all
          reasonable efforts to cause its affiliates (including any person
          who may be deemed to have become an affiliate after the date of
          the letter referred to in the prior sentence) to deliver to WPS
          on or prior to the Closing Date a written agreement substantially
          in the form attached as Exhibit 7.8 (an "Affiliate Agreement"). 
                                                   -------------------
          If any affiliate refuses to provide such a written agreement, WPS
          shall, in lieu of receipt of such written agreement, be entitled
          to place restrictive legends on the certificates evidencing that
          WPS Common Stock to be received by such affiliate pursuant to the
          terms of this Agreement, and to issue appropriate stock transfer
          instructions to the transfer agent for WPS Common Stock, to the
          effect that the shares of WPS Common Stock received or to be
          received by such affiliate pursuant to the terms of this
          Agreement may only be sold, transferred or otherwise conveyed,
          and the holder thereof may only reduce such holder's interest in
          or risk relating to such shares of WPS Common Stock, pursuant to
          an effective registration statement under the Securities Act, in
          compliance with Rule 145, as amended from time to time, or in a
          transaction which, in the opinion of legal counsel satisfactory
          to WPS, is exempt from the registration requirements of the
          Securities Act.  The restrictive legends provided for herein
          shall to the extent necessary also provide that the shares of WPS
          Common Stock received or to be received by the affiliate be held
          for the requisite period to insure that the Merger will be
          accounted for as a pooling under generally accepted accounting
          principles.  The foregoing restrictions on the transferability of
          WPS Common Stock shall apply to all purported sales, transfers
          and other conveyances of the shares of WPS Common Stock received
          or to be received by such affiliate pursuant to this Agreement
          and to all purported reductions in the interest in or risks
          relating to such shares of WPS Common Stock, whether or not such
          affiliate has exchanged the certificates previously evidencing
          such affiliates' shares of UPEN Common Stock for certificates
          evidencing shares of WPS Common Stock into which such shares were
          converted.  The Proxy Statement and the Registration Statement
          shall disclose the foregoing in a reasonably prominent manner.

                    Section 7.9    Employee Agreements.  Subject to Section
                                   -------------------              -------

          hereof which apply to any current or former employee or current
          or former director of UPEN and the UPEN Subsidiaries; provided,

          however, that this undertaking is not intended to prevent WPS
          -------
          from enforcing such contracts, agreements, collective bargaining
          agreements and commitments in accordance with their terms,
          including, without limitation, any reserved right to amend,
          modify, suspend, revoke or terminate any such contract,
          agreement, collective bargaining agreement or commitment.

          date hereof shall be maintained in effect with respect to the
          employees or former employees of UPEN and any of its Subsidiaries
          who are covered by any such Benefit Plan immediately prior to the
          Closing Date (the "Affiliated Employees") until WPS otherwise
                             --------------------
          determines after the Effective Time; provided, however, that
                                               --------  -------
          nothing herein contained shall limit any reserved right contained
          in any such UPEN Benefit Plan, to amend, modify, suspend, revoke
          or terminate any such plan.  Without limitation of the foregoing,
          each participant of any such UPEN Benefit Plan shall receive
          credit for purposes of eligibility to participate and vesting,
          under a benefit plan of WPS or any of its Subsidiaries or
          Affiliates for service credited for the corresponding purpose
          under such benefit plan; provided, however, that such crediting
                                   --------  -------
          of service shall not operate to duplicate any benefit to any such
          participant or the funding for any such benefit.  Any person
          hired by WPS or any of its Subsidiaries after the Closing Date
          who was not employed by any party hereto or its Subsidiaries
          immediately prior to the Closing Date shall be eligible to
          participate in such benefit plans maintained, or contributed to,
          by WPS or the Subsidiary, for employees of the division or
          operation in which such person is employed, provided that such

          person meets the eligibility requirements of the applicable plan.

                                   ----------------

                    (a)  UPEN shall not, and shall use its best efforts to
          cause its Subsidiaries not to, permit any of its Representatives,
          directly or indirectly initiate, solicit or encourage, or take
          any action to facilitate the making of any offer or proposal
          which constitutes or is reasonably likely to lead to, any
          Business Combination Proposal (as hereinafter defined), or, in
          the event of an unsolicited Business Combination Proposal, except
          to the extent required by their fiduciary duties under applicable
          law if so advised in a written opinion of outside counsel, engage
          in negotiations or provide any information or data to any person
          relating to any Business Combination Proposal.

                    (b)  UPEN shall notify WPS orally and in writing of any
          such inquiries, offers or proposals (including, without
          limitation, the terms and conditions of any such proposal and the
          identity of the person making it), within 24 hours of the receipt
          thereof, shall take reasonable steps to keep WPS informed of the
          status and details of any such inquiry, offer or proposal, and
          shall give WPS five days' advance notice of any agreement to be
          entered into with or any information to be supplied to any person
          making such inquiry, offer or proposal.  UPEN shall immediately
          cease and cause to be terminated all existing discussions and
          negotiations, if any, with any parties conducted heretofore with
          respect to any Business Combination Proposal.

                    (c)  As used in this Section 7.11, "Business
                                                        --------
          Combination Proposal" shall mean any tender or exchange offer,
          --------------------
          proposal for a merger, consolidation or other business
          combination involving UPEN or any of its material Subsidiaries,
          or any proposal or offer (in each case, whether or not in writing
          and whether or not delivered to the shareholders of UPEN
          generally) to acquire in any manner, directly or indirectly, a
          substantial equity interest in or a substantial portion of the
          assets of UPEN or any of its material Subsidiaries, other than
          pursuant to the transactions contemplated by this Agreement.

                    (d)  Nothing contained herein shall prohibit UPEN from
          taking and disclosing to its shareholders a position contemplated
          by Rule 14e-2(a) under the Exchange Act with respect to a
          Business Combination Proposal made by means of a tender offer.

                                   --------------------------------------
          Board.
          -----

                    (a)  WPS Board of Directors.  WPS's Board of Directors
                         ----------------------
          will take such action as may be necessary to cause the number of
          directors comprising the full Board of Directors of WPS at the
          Effective Time to be increased by one member, the class thereof
          the then current term of which extends for the longest time
          beyond the Effective Time to be increased by one member and to
          fill the vacancy thereby created by electing to the WPS Board of
          Directors a person previously designated by the UPEN Board of
          Directors and acceptable to the WPS Board of Directors.  The
          directors shall continue to be divided into three classes of
          approximately equal size.  All of the directors of WPS in office
          immediately preceding the Effective Time shall continue to be
          directors of WPS thereafter until their respective successors
          have been duly elected and qualified.  Notwithstanding the
          foregoing, if, prior to the Effective Time, such designee shall
          decline or be unable to serve, the Board of Directors of UPEN
          shall designate another person to serve in such person's stead.

                    (b)  UPPCO Advisory Board.  Promptly following the
                         --------------------
          Effective Time, WPS shall cause an advisory board to be appointed
          to assist the Board of Directors of UPPCO or of any successor
          thereto to accomplish the transition in the management of UPPCO's
          operations contemplated by this Agreement.  Such advisory shall
          be appointed for a term of two years, and five persons serving as
          outside directors of UPEN immediately prior to the effective time
          will be offered the opportunity to serve on such advisory board. 
          Each member of the advisory board will receive a fee of $10,000
          per annum for serving on such board.

                    Section 7.13   Employment Contract.  At the Effective
                                   -------------------
          Time, WPS shall cause UPPCO to enter into an employment agreement
          with Clarence R. Fisher in the form of Exhibit 7.13 hereto.

                    Section 7.14   Operations Following the Effective Time.
                                   ---------------------------------------

                    (a)  Relationships with Local Suppliers.  During the
                         ----------------------------------
          period ending three years after the Effective Time, to extent
          reasonably practicable and consistent with the past practices of
          WPS, WPS shall cause supplies and services for UPPCO to be
          purchased from vendors located in the service area of UPPCO, so
          long as goods and services available and prices and fees charged
          by such vendors are reasonably competitive with alternative
          vendors outside such service area and the quality of such
          supplies and services is reasonably comparable to that of such
          alternative vendors.

                    (b) Charitable and Community Support Activities. 
                        -------------------------------------------
          During the period ending five years after the Effective Time, WPS
          shall provide, or shall cause its Subsidiaries (including, but
          not limited to, UPPCO) to provide, charitable contributions and
          community support within the service area of UPPCO at aggregate
          levels not less than the average annual level of total charitable
          contributions and community support provided by UPEN and its
          Subsidiaries during the three calendar years immediately prior to
          the date of this Agreement.

                    Section 7.15   Workforce Matters.  Subject to
                                   -----------------
          applicable collective bargaining agreements, WPS will offer
          employment opportunities to employees of UPPCO on terms and
          conditions consistent with the employment opportunities offered
          to employees of WPS or its subsidiaries.  To the extent that any
          of such employees are transferred from UPPCO to any affiliate or
          subsidiary of WPS, WPS will provide relocation assistance and
          benefits to such employees on terms comparable to those offered
          by WPS to its own employees.  To the extent that any reductions
          in workforce are deemed to be required, such reductions shall be
          made on a fair and equitable basis, in light of the circumstances
          and the objective to be achieved giving appropriate consideration
          to previous work history, job experience, and qualifications, and
          treating all employees equally, without regard to whether prior
          employment was with WPS or any of its Subsidiaries.  WPS and UPEN
          will consult with each other with respect to the retention of
          personnel pending the Effective Time.

                    Section 7.16   Expenses.  Subject to Section 9.3, all
                                   --------              -----------
          costs and expenses incurred in connection with this Agreement and
          the transactions contemplated hereby shall be paid by the party
          incurring such expenses.

                    Section 7.17   Further Assurances.  Each party will,
                                   ------------------
          and will cause its Subsidiaries and, will use its best efforts to
          cause its Joint Ventures to, execute such further documents and
          instruments and take such further actions as may reasonably be
          requested by the terms hereof.  The parties expressly acknowledge
          and agree that, although it is their current intention to effect
          a business combination between themselves in the form
          contemplated by this Agreement, it may be preferable to
          effectuate such a business combination by means of an alternative
          structure in light of the conditions set forth in Section 8.1(e),
                                                            --------------
          Section 8.2(e), Section 8.2(f), Section 8.3(e) and Section
          --------------  --------------  --------------     -------
          8.3(f).  Accordingly, if the only conditions to the parties'
          ------
          obligations to consummate the Merger which are not satisfied or
          waived are receipt of any one or more of the WPS Required
          Consents, WPS Required Statutory Approvals, UPEN Required
          Consents, UPEN Required Statutory Approvals or the opinions
          referred to in Sections 8.2(e) and 8.3(e), and the adoption of an
                         ---------------     ------
          alternative structure (that otherwise substantially preserves for
          WPS and UPEN the economic and other material benefits of the
          Merger) would result in such conditions being satisfied or
          waived, then the parties shall use their respective best efforts
          to effect a business combination among themselves by means of a
          mutually agreed upon structure other than the Merger that so
          preserves such benefits; provided that, prior to closing any such
                                   --------
          restructured transaction, all material third party and
          Governmental Authority declarations, filings, registrations,
          notices, authorizations, consents or approvals necessary to
          effect such alternative business combination shall have been
          obtained and all other conditions to the parties' obligations to
          consummate the Merger, as applied to such alternative business
          combination, shall have been satisfied or waived.

                    Section 7.18   Charter and By-law Amendments.  Prior to
                                   -----------------------------
          the Closing, WPS shall cause its By-laws to be amended as
          contemplated in Section 7.12.

                    Section 7.19   Pooling; Long Term Stock Incentive Plan.
                                   ---------------------------------------
          UPEN shall not, nor shall UPEN permit any of its Subsidiaries or,
          within the exercise of its best efforts, its Joint Ventures to,
          take any action which would, or would be reasonably likely to,
          prevent WPS from accounting for the transactions to be effected
          pursuant to this Agreement as a pooling of interests in
          accordance with GAAP and applicable SEC regulations, and UPEN
          shall use all reasonable efforts to achieve such result
          (including taking such actions as may be necessary to cure any
          facts or circumstances that could prevent such transactions from
          qualifying for pooling-of-interests accounting treatment).

                    Section 7.20   Tax-free Status.  Neither party shall,
                                   ---------------
          nor shall either party permit any of its Subsidiaries or, within
          the exercise of its best efforts, its Joint Ventures to, take any
          actions which would, or would be reasonably likely to, adversely
          affect the status of the Merger as a reorganization under
          Section 368(a) of the Code, and each party hereto shall use all
          --------------
          reasonable efforts to achieve such result.

                    Section 7.21   Cooperation, Notification.  Each party
                                   -------------------------
          shall, and shall cause its Subsidiaries and shall use its best
          efforts to cause, its Joint Ventures to 

                    (a)  cause its appropriate representatives to confer on
          a regular and frequent basis with one or more representatives of
          the other party to discuss, subject to applicable law, material
          operational matters and the general status of its ongoing
          operations; 

                    (b)  promptly notify the other party of any significant
          changes in its business, properties, assets, condition (financial
          or other), results of operations or prospects; 

                    (c)  advise the other party of any change or event
          which has, had or, insofar as reasonably can be foreseen, is
          reasonably likely to result in, in the case of WPS, a WPS
          Material Adverse Effect or in the case of UPEN, an UPEN Material
          Adverse Effect; and 

                    (d)  promptly provide the other party with copies of
          all filings made by such party or any of its Subsidiaries with
          any state or Federal court, administrative agency, commission or
          other Governmental Authority in connection with this Agreement
          and the transactions contemplated hereby.

                    Section 7.22   Third-party Consents.
                                   --------------------

                    (a)  WPS shall, and shall cause its Subsidiaries to,
          use all commercially reasonable efforts to obtain all WPS
          Required Consents.  WPS shall promptly notify UPEN of any failure
          or prospective failure to obtain any such consents and, if
          requested by UPEN, shall provide copies of all WPS Required
          Consents obtained by WPS to UPEN.

                    (b)  UPEN shall, and shall cause its Subsidiaries to,
          use all commercially reasonable efforts to obtain all UPEN
          Required Consents.  UPEN shall promptly notify WPS of any failure
          or prospective failure to obtain any such consents and, if
          requested by WPS, shall provide copies of all UPEN Required
          Consents obtained by UPEN to WPS.

          expressly speak only as of a specific date or time other than the

          (ii) for such failures of representations or warranties to be

          applicability to electric or gas utility companies in the region
          in which WPS conducts its utility operations) which have, or

               said opinions.

          shareholders under the WPS Rights Agreement, including a "flip
          in" or "flip over" or similar event commonly described in such
          rights plans has occurred, which, in the reasonable judgment of
          UPEN, would have or be reasonably likely to result in a WPS
          Material Adverse Effect or materially change the number of
          outstanding equity securities of WPS, and the WPS Rights shall
          not have become nonredeemable by any action of the WPS Board of
          Directors.

          other party, if the Effective Time shall not have occurred on or
          before December 31, 1998 (the "Initial Termination Date");
                                         ------------------------
          provided, however, that the right to terminate the Agreement

          under this Section 9.1(b) shall not be available to any party
                     --------------
          whose failure to fulfill any obligation under this Agreement has
          been the cause of, or resulted in, the failure of the Effective
          Time to occur on or before the Initial Termination Date; and
          provided, further, that if on the Initial Termination Date the

                 ------
          conditions to the Closing shall be fulfilled or shall be capable
          of being fulfilled, then the Initial Termination Date shall be
          extended to June 30, 1999;

                    (c)  by either party hereto, by written notice to the
          other parties, if the UPEN Shareholders' Approval shall not have
          been obtained at a duly held UPEN meeting thereof, including any
          adjournments thereof;

                    (d)  by either party hereto, if any state or Federal
          law, order, rule or regulation is adopted or issued, which has
          the effect, as supported by the written opinion of outside
          counsel for such party, of prohibiting the Merger or by either

          States or any State shall have issued an order, judgment or
          decree permanently restraining, enjoining or otherwise
          prohibiting the Merger, and such order, judgment or decree shall
          have become final and nonappealable;

                    (e)  by UPEN, upon two days' prior notice to WPS, if,
          as a result of a tender offer by a party other than WPS or any
          WPS Affiliate or any written offer or proposal with respect to a
          merger, sale of a material portion of its assets or other

          other than WPS or any WPS Affiliates, the Board of Directors of
          UPEN determines in good faith that its fiduciary obligations
          under applicable law require that such tender offer or other
          written offer or proposal be accepted; provided, however, that
                                                 --------  -------

                         (i)  the Board of Directors of UPEN shall have

               entered into in the proper exercise of its applicable
               fiduciary duties, and after giving due consideration to all
               concessions which may be offered by WPS in negotiations
               entered into pursuant to clause (ii) below, such fiduciary
                                        -----------
               duties would require the directors to reconsider such
               commitment as a result of such tender offer or other written
               offer or proposal; and

                         (ii) prior to any such termination, UPEN shall,
               and shall cause its respective financial and legal advisors
               to, negotiate with WPS to make such adjustments in the terms
               and conditions of this Agreement as would enable UPEN to
               proceed with the transactions contemplated herein on such
               adjusted terms;

               breaches and requesting that they be remedied;

                         (ii)  WPS (and/or its appropriate Subsidiaries) 
               shall have failed to perform and comply with, in all
               material respects, their other agreements and covenants
               hereunder and such failure to perform or comply shall not
               have been remedied within 20 days after receipt by WPS, of
