Dear Shareholders:
 
   
     You are cordially invited to attend the 1996 Annual Meeting of Shareholders
of North Star Universal, Inc. ("NSU") to be held at     p.m. local time on
          , 1996, at the Marriott Southwest, 5801 Opus Parkway, Minnetonka,
Minnesota.
    
 
   
     As you are aware, on December 21, 1995, NSU and Michael Foods, Inc.
("Michael") entered into an Agreement and Plan of Reorganization (the
"Reorganization Agreement") pursuant to which (i) NSU Merger Co., a Delaware
corporation and wholly-owned subsidiary of NSU ("Merger Co."), will be merged
with and into Michael and Michael will become a wholly-owned subsidiary of NSU
(the "Merger"), (ii) each stockholder of Michael (other than NSU) will receive,
in exchange for each share of common stock, par value $.01 per share, of Michael
("Michael Common Stock"), held by such stockholder, one share of the common
stock, par value $.01 per share, of NSU ("NSU Common Stock"), (iii) each share
of Michael Common Stock held by NSU will be canceled and retired, (iv) NSU will
change its name to Michael Foods, Inc. (NSU after the consummation of the Merger
is referred to hereinafter as "New Michael") and will continue the business
previously conducted by Michael, (v) prior to the consummation of the Merger,
NSU will transfer all of its assets and liabilities other than certain
indebtedness and other agreed upon assets and liabilities to another
wholly-owned subsidiary of NSU, ENStar Inc. ("ENStar"), (vi) the outstanding
common stock of ENStar will be distributed pro rata by NSU to the shareholders
of NSU of record as of a record date just prior to the effective date of the
Merger (the "Distribution"), and (vii) immediately prior to the effective time
of the Merger, NSU will effectuate a reverse stock split (the "Reverse Stock
Split"), the ratio of the Reverse Stock Split to be determined pursuant to the
terms of the Reorganization Agreement, as described in the accompanying Proxy
Statement/Prospectus under "THE REORGANIZATION -- Effects of the
Reorganization." The above-referenced transactions are herein collectively
referred to as the "Reorganization."
    
 
     In addition to the election of six directors to the Board of Directors of
NSU, at the Annual Meeting you will be asked to consider and vote upon the
following proposals in connection with the Reorganization:
 
      (i) a proposal to approve the Reorganization Agreement and the Merger;
 
      (ii) a proposal to approve the Reverse Stock Split;
 
     (iii) a proposal to approve the Distribution; and
 
     (iv) a proposal to approve an amendment to the Restated Articles of
          Incorporation of NSU (collectively, the "NSU Proposals").
 
   
At the same time, Michael shareholders will be meeting to approve the
Reorganization Agreement and the Merger. Your board of directors believes that
the Reorganization is in the best interest of NSU and its shareholders and has
unanimously approved the NSU Proposals. Approval of each of the NSU Proposals by
the requisite vote of the NSU shareholders is required or the Reorganization
will not be consummated. THE BOARD UNANIMOUSLY RECOMMENDS THAT YOU VOTE "FOR"
THE NSU PROPOSALS.
    
 
     Pursuant to an Orderly Disposition and Registration Rights Agreement
between NSU and James H. Michael and Jeffrey J. Michael, each a member of the
Board of Directors of NSU, and two limited partnerships controlled by them (the
"Michael Family Shareholders"), the Michael Family Shareholders, which own an
aggregate of 5,685,100 shares of the outstanding NSU Common Stock (approximately
60.17% of the outstanding shares of NSU Common Stock as of the date hereof) have
agreed to vote in favor of the NSU Proposals. IF THE MICHAEL FAMILY SHAREHOLDERS
VOTE IN ACCORDANCE WITH THAT AGREEMENT, THE APPROVAL OF THE NSU PROPOSALS IS
ASSURED.
<PAGE>   5
 
   
     Consummation of the Reorganization is subject to certain conditions,
including approval and adoption of the Reorganization Agreement and the Merger
by the affirmative vote of the holders of a majority of the outstanding shares
of Michael Common Stock, the approval of the NSU Proposals by the affirmative
vote of the holders of a majority of the NSU Common Stock, a favorable tax
ruling from the Internal Revenue Service and the receipt of certain approvals
from regulatory authorities. In addition, NSU's obligation to consummate the
Merger is subject to the condition that holders of not more than 1% of the
outstanding shares of NSU Common Stock effectively elect statutory dissenters'
rights, which condition may be waived by NSU. See "THE REORGANIZATION --
Dissenters' Rights" in the accompanying Proxy Statement/Prospectus.
    
 
     The accompanying Proxy Statement/Prospectus provides detailed information
concerning the Reorganization, the NSU Proposals, and certain additional
information, which you are urged to read carefully. It is important that your
shares be represented at the annual meeting regardless of the number you hold.
Whether or not you plan to attend the annual meeting, you are requested to
complete, date, sign and return the proxy card in the enclosed postage paid
envelope. You may revoke your proxy at any time prior to its exercise at the
annual meeting by written notice of revocation to the secretary of Michael, by
signing and returning a later dated proxy or by voting in person at the annual
meeting.
 
     Please do not send in your stock certificates at this time. In the event
the Reorganization is consummated, you will be sent a letter of transmittal for
that purpose.
 
                                          Sincerely,

Agreement pursuant to which: (i) Merger Co. will be merged with and into Michael
and Michael will become a wholly-owned subsidiary of NSU; (ii) in the Merger,
each stockholder of Michael (other than NSU) will receive, in exchange for each
share of Michael Common Stock held by such stockholder, one share of NSU Common
 
                                        8

Stock; (iii) each share of Michael Common Stock held by NSU will be canceled and
retired; (iv) NSU will change its name to Michael Foods, Inc. and will continue
the business previously conducted by Michael; (v) prior to the consummation of
the Merger, NSU will transfer all of its assets and liabilities other than
certain indebtedness and other agreed upon assets and liabilities to ENStar;
(vi) the outstanding common stock of ENStar will, conditioned on the
consummation of the Merger, be distributed pro rata to the shareholders of NSU
of record as of a record date prior to the Effective Date of the Merger; and
(vii) immediately prior to the Effective Time of the Merger, NSU will effectuate
the Reverse Stock Split, the ratio of the Reverse Stock Split to be determined
pursuant to the terms of the Reorganization Agreement, as described below under
"THE REORGANIZATION -- Effects of the Reorganization."
    
 
EFFECT OF THE REORGANIZATION ON MICHAEL STOCKHOLDERS
 
   
     Upon the consummation of the Merger, each outstanding share of Michael
Common Stock, other than the Michael Common Stock owned by NSU, will be
converted into the right to receive one share of NSU Common Stock, which, after
the Reorganization, is also referred to herein as New Michael Common Stock. Upon
the consummation of the Merger, each outstanding share of Michael Common Stock
owned by NSU will be canceled and retired without any payment therefor. See "THE
REORGANIZATION -- Effects of the Reorganization" and "THE REORGANIZATION
AGREEMENT -- Effects of the Reorganization on the Stockholders of Michael and
the Shareholders of NSU." For a description of the New Michael Common Stock, see
"DESCRIPTION OF NEW MICHAEL CAPITAL STOCK." As a result of the Reorganization,
New Michael will continue the business of Michael and each stockholder of
Michael prior to the Reorganization will own the same number of shares of New
Michael Common Stock after the Reorganization as such stockholder owned of
Michael before the Reorganization. As a result of the retirement of a portion of
the NSU Common Stock through the Reverse Stock Split and the corresponding
assumption by New Michael of NSU Net Indebtedness, the pro forma book value per
share of New Michael Common Stock will be reduced from the book value per share
of Michael Common Stock prior to the Reorganization. See "SUMMARY -- Comparative
Per Share Data." For a summary of the principal differences between the rights
of holders of NSU Common Stock before and after the Reorganization, see
"COMPARISON OF RIGHTS OF NSU SHAREHOLDERS BEFORE AND AFTER THE REORGANIZATION."
    
 
EFFECT OF THE REORGANIZATION ON NSU SHAREHOLDERS.
 
   
     Reverse Stock Split. Immediately prior to the Effective Time, NSU will
effect the Reverse Stock Split whereby each outstanding share of NSU Common
Stock will be combined into a fraction of one share of NSU Common Stock
determined by multiplying each such share by a fraction where the denominator is
the number of outstanding shares of NSU Common Stock immediately prior to the
Effective Date, and the numerator is the number of shares of Michael Common
Stock owned by NSU at such date less the number of shares of Michael Common
Stock owned by NSU which are retired in consideration for the assumption of the
"Net Indebtedness," as hereinafter defined, of NSU by New Michael. The amount of
the Net Indebtedness of NSU to be retained by New Michael is equal to the sum of
the subordinated debentures, subordinated fixed-term time certificates,
subordinated extendible time certificates and bank debt of NSU outstanding
immediately prior to the Effective Time plus the "Dissenting Shares Holdback,"
as hereinafter defined, less any cash retained by NSU at the Effective Time of
the Merger. Pursuant to the terms of the Reorganization Agreement, NSU has
indicated to Michael that the amount of the Net Indebtedness, excluding the
amount of the Dissenting Shares Holdback, will not be less than $25 million or
more than $29 million. The Dissenting Shares Holdback is an amount to be
mutually agreed by Michael and NSU as a reserve to pay for the shares of NSU
Common Stock as to which dissenters' rights properly have been exercised. See
"THE REORGANIZATION -- Effects of the Reorganization" and "THE REORGANIZATION
AGREEMENT -- Effects of the Reorganization on the Stockholders of Michael and
the Shareholders of NSU." While the amount of the Dissenting Shares Holdback has
not yet been agreed to by Michael and NSU, it is anticipated that such amount
will be determined by adding (i) the product of (A) the number of shares of NSU
Common Stock held by persons that have effectively elected to exercise their
dissenters' rights, times (B) the trading price of the NSU Common Stock
immediately prior to the Effective Date, plus (ii) an amount equal to some
portion of the product described above in the event that a court were to find
that the trading price for NSU's Common
    
 
                                        9
<PAGE>   18
 
   
Stock does not equal its fair value. NSU has indicated that it intends to retain
cash in an amount at least equal to the Dissenting Shares Holdback so that Net
Indebtedness will be between $25 million and $29 million.
    
 
     Distribution. Prior to the Effective Date, NSU will transfer all of its
assets and liabilities other than the Michael Common Stock owned by NSU, all of
the outstanding common stock of Merger Co., cash in an amount to be determined
by NSU and a certain amount of NSU indebtedness to ENStar and declare a
contingent dividend of all of its ENStar Common Stock, payment of which will be
subject to the prior consummation of the Merger. Immediately after the Effective
Time, the ENStar Common Stock will be distributed by NSU as a tax-free dividend
to NSU shareholders of record as of a record date prior to the Effective Date.
See "THE DISTRIBUTION AGREEMENT." Holders of Michael Common Stock will not
receive any ENStar Common Stock as a result of the Reorganization.
 
EXCHANGE OF CERTIFICATES; DISTRIBUTION OF ENSTAR COMMON STOCK
 
     As soon as practicable after the Effective Date, The First National Bank of
Boston, or another person mutually designated by Michael and NSU, in its
capacity as exchange agent for the Merger and the Reverse Stock Split (the
"Exchange Agent"), will send a transmittal letter to each holder of Michael
Common Stock and each holder of NSU Common Stock as of the Effective Date. The
transmittal letter will contain instructions with respect to the surrender of
certificates representing the Michael Common Stock and NSU Common Stock to be
exchanged for certificates evidencing the New Michael Common Stock in the
Merger. On or prior to the Effective Date, NSU will deliver to its Exchange
Agent certificates representing all of the outstanding shares of ENStar Common
Stock. Immediately after the Effective Time, NSU will deliver to such Exchange
Agent instructions to distribute, as promptly as practicable following the
Effective Date, to each holder of record of NSU Common Stock on the record date
for the Distribution, stock certificates evidencing one share of ENStar Common
Stock for every three shares of NSU Common Stock held of record by such holder
on such record date and cash in lieu of any fractional shares of ENStar Common
Stock. See "THE REORGANIZATION -- Procedure for Exchange of Certificates."
 
MICHAEL STOCKHOLDERS AND NSU SHAREHOLDERS SHOULD NOT FORWARD CERTIFICATES TO THE
EXCHANGE AGENT UNTIL THEY HAVE RECEIVED TRANSMITTAL LETTERS. MICHAEL
STOCKHOLDERS AND NSU SHAREHOLDERS SHOULD NOT RETURN STOCK CERTIFICATES WITH THE
ENCLOSED PROXY.
 
OWNERSHIP OF NEW MICHAEL AFTER THE REORGANIZATION
 
   
     Following the Reorganization, NSU's only assets will consist of all of the
outstanding capital stock of Michael, certain contractual rights and retained
cash. In order to avoid confusion, on the Effective Date, NSU will change its
name to Michael Foods, Inc. and transactions in New Michael Common Stock will
continue to be reported on the Nasdaq National Market under the symbol MIKL.
Michael will change its name to Michael Foods of Delaware, Inc. At the date of
this Proxy Statement/Prospectus, NSU owns, directly and beneficially, 7,354,950
shares of the outstanding common stock of Michael, or approximately 38% of such
securities. Holders of Michael Common Stock immediately prior to the Merger,
excluding NSU, will own directly and beneficially approximately 67.6% to 73% of
New Michael Common Stock outstanding immediately after the Merger depending upon
the amount of the Net Indebtedness retained by New Michael. Correspondingly, NSU
shareholders immediately prior to the Merger will own, directly and
beneficially, approximately 27% to 32.4% of the outstanding New Michael Common
Stock immediately after the Merger.
    
 
   
BACKGROUND OF THE REORGANIZATION
    
 
   
     From time to time since 1990, NSU and Michael senior management have
discussed various possible tax-advantaged transactions that would result in all
or a portion of NSU's substantial ownership interest in Michael being held
directly by NSU shareholders. Certain transactions discussed involved the
assumption of some or all of NSU's outstanding indebtedness in consideration of
the retirement of some of the Michael Common Stock held by NSU. Although a
number of alternative transactions and transaction structures were
    
 
                                       10
<PAGE>   19
 
   
discussed, agreement was never reached on any particular transaction,
transaction structure or related financial terms and none of these discussions
progressed beyond the preliminary discussion stage.
    
 
   
     In the summer of 1994, NSU contacted Michael to hold discussions again in
an effort to structure a mutually acceptable transaction that would provide for
the assumption by Michael of some or all of NSU's outstanding indebtedness and
permit NSU shareholders to directly own NSU's interest in Michael. During
subsequent meetings between NSU and Michael senior management the following
fundamental elements in any transaction were determined: (i) any transaction
could not result in federal income tax to the parties or their respective
shareholders; (ii) the amount of NSU indebtedness assumed by Michael in any
transaction had to be within parameters to be agreed upon; (iii) the Michael
Common Stock to be retired in consideration for the debt assumed in any
transaction had to be valued at a discount to the market; and (iv) Michael had
to be protected from the liabilities of NSU relating to the operations of NSU
(other than its investment in Michael Common Stock). Michael and its financial
advisors also concluded that the transfer of all other assets and liabilities of
NSU to a separate company to be spun-off to the NSU shareholders or some other
disposition of such assets and satisfaction of such liabilities was necessary in
order to avoid higher costs of capital that would otherwise occur if such assets
and liabilities were retained after the Reorganization and to avoid the adverse
impact on the value of Michael Common Stock if New Michael were engaged in
businesses unrelated to its core food processing and distribution businesses. As
a result of these discussions, senior management of both companies, with the
assistance of their respective tax and legal advisors, developed a general
transaction structure proposal that satisfied the parties' fundamental
requirements. No agreement was reached, however, on the financial terms, or on
certain of the other terms of this proposal.
    
 
   
     Once a potentially acceptable transaction structure proposal had been
developed, advisors of both companies were directed to obtain a preliminary
indication from the IRS as to the tax treatment of the proposal. Discussions
with the IRS occurred during the spring and summer of 1995, which led senior
management of both companies to conclude that there were reasonable prospects
for receipt of a favorable ruling concerning the tax-free nature of the
transaction structure proposal.
    
 
   
     Following the discussions with the IRS, NSU engaged its financial advisor,
Goldsmith, Agio, Helms Securities Inc. ("GAHS"), in July 1995. Michael had
previously engaged its financial advisor, Piper Jaffray Inc. ("Piper Jaffray"),
in April 1995.
    
 
   
     Beginning in September 1995, senior management of NSU and Michael, and
their respective legal, tax and financial advisors, began meeting to discuss the
financial and other terms relating to the transaction proposal that had been
developed and discussed with the IRS. On October 27, 1995, Michael's management
informed the Michael Board of the status of negotiations with NSU and the
principal terms of the transaction proposal that was currently under
consideration by Michael senior management. Messrs. Jeffrey J. Michael, James H.
Michael and Miles E. Efron, each a member of the board of directors of both NSU
and Michael, at the request of Michael, did not participate in this discussion.
At the NSU Board meeting held on November 7, 1995, NSU's management and its
financial advisor discussed with the NSU Board the principal terms of the
transaction proposal that was currently under consideration by NSU senior
management. The NSU Board, after such discussion, directed and authorized
certain officers of NSU to negotiate the terms of a definitive agreement with
respect to the transaction proposal, subject to final board review and approval.
    
 
   
     Over the next several weeks, the terms of the definitive agreement were
negotiated and a definitive agreement was presented to each of the NSU and
Michael Boards at separate meetings held on December 21, 1995. Messrs. Michael,
Michael and Efron recused themselves from participation in the meeting of the
Michael Board. The Boards of Directors of NSU and Michael approved the
Reorganization Agreement at their respective meetings held on that date, at
which meetings each Board received the opinion of its respective financial
advisors as to the fairness of the transactions contemplated by the
Reorganization Agreement. See "SUMMARY -- Opinions of Financial Advisors." The
Reorganization Agreement was executed by NSU and Michael later that same day.
See "THE REORGANIZATION -- Background of the Reorganization."

RECOMMENDATION OF MICHAEL BOARD; MICHAEL'S REASONS FOR THE REORGANIZATION
 
   
     The Board of Directors of Michael (the "Michael Board") (with James H.
Michael, Jeffrey J. Michael and Miles E. Efron, each of whom is also a director
of NSU, having recused themselves from any discussions of and vote on the
proposed transaction), has determined that the Reorganization is in the best
interest of Michael and recommends that the holders of Michael Common Stock vote
in favor of the Reorganization Agreement and the Merger. The decision of the
Michael Board to enter into the Reorganization and to recommend that its
stockholders vote in favor of the Reorganization Agreement and the Merger is
based upon its evaluation of a number of factors, including, among others, the
opinion of Piper Jaffray that the consideration given up by Michael in the form
of the Net Indebtedness retained by New Michael after the Merger, in exchange
for the shares of Michael Common Stock held by NSU that will be retired in the
Merger, and the exchange of Michael Common Stock for NSU Common Stock, is fair
to Michael from a financial point of view. See "THE REORGANIZATION --
Recommendation of Michael Board; Michael's Reasons for the Reorganization;" and
"THE REORGANIZATION -- Fairness Opinions."
    
 
RECOMMENDATION OF NSU BOARD; NSU'S REASONS FOR THE REORGANIZATION
 
   
     The Board of Directors of NSU (the "NSU Board"), by unanimous vote,
determined that the consummation of the Reorganization, including the Merger,
the Reverse Stock Split and the Distribution, is in the best interest of the
holders of NSU Common Stock and recommends that the holders of NSU Common Stock
vote in favor of the NSU Proposals. The decision of the NSU Board to enter into
the Reorganization Agreement and to make the foregoing recommendations is based
upon its evaluation of a number of factors including, among others, the opinion
of GAHS, that the Reorganization is fair to the Shareholders of NSU from a
financial point of view. See "THE REORGANIZATION -- Recommendation of NSU Board;
NSU's Reasons for the Reorganization;" and "THE REORGANIZATION -- Fairness
Opinions."
    
 
OPINIONS OF FINANCIAL ADVISORS
 
   
     Michael. On December 21, 1995, Piper Jaffray rendered to the Michael Board
its oral and written opinion to the effect that, based upon and subject to the
matters set forth in its written opinion, as of such date, that the
consideration given up by Michael in exchange for the shares of Michael Common
Stock held by NSU that will be retired in the Merger, and the exchange of
Michael Common Stock for NSU Common Stock is fair to Michael from a financial
point of view. The full text of the written opinion of Piper Jaffray dated as of
the date of this Proxy Statement/Prospectus, which sets forth the assumptions
made, factors considered and scope of the review undertaken by Piper Jaffray, is

     NSU. On December 21, 1995, GAHS rendered to the NSU Board its oral and
written opinion to the effect that the Reorganization is fair to NSU's
shareholders from a financial point of view. The full text of the written
opinion of GAHS, dated as of the date of this Proxy Statement/Prospectus, which
sets forth the assumptions made, factors considered and limitations on the
review undertaken by GAHS is included as Appendix III to this Proxy
Statement/Prospectus. NSU shareholders are urged to read such opinion carefully
in its entirety. GAHS has been paid $77,500 for its financial advisory services
to date, including $25,000 in connection with the delivery of its fairness
opinion on December 21, 1995. If the Reorganization is consummated, GAHS will
receive an additional $175,000 to $225,000, depending upon the amount of the
Discount Factor (as defined herein), for its financial advisory services and
$75,000 for the issuance of its fairness opinion. See "THE REORGANIZATION --

THE REORGANIZATION AGREEMENT
 
     Representations, Warranties and Covenants. The Reorganization Agreement
contains various representations and warranties of NSU and Michael relating to
the organization and operations of such entities. See "THE REORGANIZATION
AGREEMENT -- Representations and Warranties." In the Reorganization
 
                                       12
<PAGE>   21
 
Agreement, NSU and Michael have made certain covenants with respect to the
conduct of their respective businesses and certain actions to be taken between
the date of the Reorganization Agreement and the Effective Date. See "THE
REORGANIZATION AGREEMENT -- Certain Covenants."
 
   
     Conditions to the Reorganization. The obligations of Michael and NSU to
consummate the transactions contemplated under the Reorganization Agreement are
subject to various conditions including, but not limited to: (i) the accuracy of
representations and warranties of the other party; (ii) the receipt of a
favorable ruling from the Internal Revenue Service (the "IRS") that the Merger,
the Reverse Stock Split and the Distribution will not result in taxable gain or
loss; (iii) the effectiveness of the registration statement filed with the
Commission under the Securities Act with regard to the shares of NSU Common
Stock to be exchanged for Michael Common Stock (the "NSU Registration
Statement") and of a registration statement filed with the Commission under the
Securities Act with regard to the shares of ENStar Common Stock to be
distributed in the Distribution (the "ENStar Registration Statement"); (iv)
obtaining requisite stockholder and shareholder approvals; (v) the absence of
any injunction or other order that would prohibit or make illegal the
consummation of the Reorganization Agreement; (vi) the approval of Nasdaq for
the trading of New Michael Common Stock and the ENStar Common Stock on the
Nasdaq National Market; (vii) holders of fewer than 1% of the issued and
outstanding NSU Common Stock effectively electing statutory dissenters' rights;
and (viii) obtaining requisite governmental and third party consents. Neither
Michael nor NSU has any present intention to modify or waive any of the
conditions to consummating the transactions contemplated by the Reorganization
Agreement; provided, however, that, depending upon the facts and circumstances
at the time, with prior board approval either Michael or NSU may modify or waive
any of the conditions. See "THE REORGANIZATION AGREEMENT -- Conditions."
    
 
   
     In the event that a material condition to the obligations of NSU or Michael
to consummate the Reorganization is waived by NSU or Michael, including but not
limited to waiver of the receipt of a private letter ruling from the IRS or a
tax opinion as to certain tax issues (see "THE REORGANIZATION--Certain Federal
Income Tax Consequences"), NSU and Michael undertake to file a post-effective
amendment to the Registration Statement and to resolicit the approval of the
Reorganization by Michael stockholders and the approval of the NSU Proposals by
NSU shareholders pursuant to an amended Proxy Statement/Prospectus contained in
the amended Registration Statement, or ENStar Registration Statement, if such
resolicitation is required by law or deemed necessary by Michael or NSU,
respectively, after consultation with counsel.
    
 
     Termination. The Reorganization Agreement may be terminated at any time
prior to the Effective Time, whether before or after approval of the matters
presented to the stockholders of Michael or the shareholders of NSU at their
respective Annual Meetings: (i) by mutual written consent of the Boards of
Directors of Michael and NSU; (ii) by either party, if any of the conditions to
such party's obligation to complete the transactions become impossible to
satisfy; (iii) by either party if the requisite stockholder vote or shareholder
vote has not been obtained; (iv) by either party if the transactions have not
been completed on or before September 30, 1996; (v) by NSU if the "Average Price
of Michael Common Stock," as hereinafter defined, is less than $11.00 per share;
(vi) by Michael if the Average Price of Michael Common Stock is more than $17.00
per share; and (vii) by either party if any representation or warranty of the
other party becomes untrue, subject to certain exceptions. Under certain
circumstances, Michael or NSU may recover from the other party out-of-pocket
costs, including fees and expenses of attorneys, accountants and investment
bankers, up to an aggregate of $500,000 if the Reorganization Agreement is
terminated by the other party. Entitlement to such reimbursement is the sole and
exclusive remedy of a party for any termination of the Reorganization Agreement.
See "THE REORGANIZATION AGREEMENT -- Termination," and "THE REORGANIZATION
AGREEMENT -- Expenses."
 
THE DISTRIBUTION AGREEMENT
 
     The Distribution Agreement is attached to the Reorganization Agreement as
Exhibit C and included as a part of Appendix I of this Proxy
Statement/Prospectus. The Reorganization Agreement provides that NSU will, and
will cause ENStar to, execute and deliver the Distribution Agreement prior to
the Effective Date. The Distribution Agreement requires NSU to contribute and
transfer to ENStar or an ENStar subsidiary all
 
                                       13
<PAGE>   22
 
   
of NSU's right, title and interest in and to all of NSU's assets, except for the
following assets to be retained by New Michael: (i) cash in an amount to be
determined by NSU, (ii) the 7,345,950 shares of Michael Common Stock owned by
NSU, (iii) the capital stock of Merger Co., (iv) the rights of NSU under the
Reorganization Agreement, the Distribution Agreement and the Orderly Disposition
Agreement and (v) all net operating loss carryforwards and other tax attributes
properly allocable to NSU following the Effective Date. In addition, ENStar will
assume and has agreed to pay, perform and discharge all liabilities of NSU
arising at any time prior to the Effective Time, other than the following
liabilities to be retained by New Michael: (i) liabilities arising from the
assertion of dissenters' rights by NSU shareholders, (ii) obligations under the
Reorganization Agreement, the Distribution Agreement and the Orderly Disposition
Agreement, and (iii) NSU's indebtedness (including principal and accrued
interest, "NSU Indebtedness") represented by NSU's outstanding subordinated
debentures, subordinated extendible time certificates, subordinated fixed time
certificates and bank debt. Pursuant to the terms of the Reorganization
Agreement, NSU has indicated to Michael that the amount of NSU Indebtedness,
excluding the Dissenting Shares Holdback, to be assumed, less the amount of cash
retained by NSU, will be no lower than $25 million and no greater than $29
million. New Michael is required, pursuant to the Distribution Agreement, to
repay in full all NSU Indebtedness not later than six months after the Effective
Date. The Distribution is expressly conditioned on the prior consummation of the
Merger and the satisfaction of certain other conditions set forth in the
Distribution Agreement. In the Distribution, each NSU shareholder of record on
the record date for the Distribution will receive one share of ENStar Common
Stock for every three shares of NSU Common Stock held by such holder on such
date, which date will be prior to the Effective Date and prior to the Reverse
Stock Split. The Distribution Agreement also requires ENStar and New Michael to
indemnify each other for certain losses and liabilities arising before or after
the Effective Time. See "THE DISTRIBUTION AGREEMENT."
    
 
THE ORDERLY DISPOSITION AGREEMENT
 
     Concurrently with the execution of the Reorganization Agreement, the
Michael Family Shareholders, which own an aggregate of 5,685,100 shares of the
outstanding NSU Common Stock (approximately 60% of the outstanding shares of NSU
Common Stock as of the date hereof), and NSU entered into that certain Orderly
Disposition and Registration Rights Agreement, dated December 21, 1995 (the
"Orderly Disposition Agreement"). The Orderly Disposition Agreement is attached
as Exhibit E to the Reorganization Agreement and included as part of Appendix I
of this Proxy Statement/Prospectus. Under the Orderly Disposition Agreement, the
Michael Family Shareholders have agreed, among other things, to vote the shares
of NSU Common Stock owned by them in favor of the NSU Proposals. The Michael
Family Shareholders have also agreed to refrain for a period of two years after
the Merger from selling, pledging or otherwise disposing of any of the shares of
New Michael Common Stock owned by them if the purchaser of such shares owns or
would own more than five percent of the outstanding New Michael Common Stock,
unless New Michael is first given an opportunity to purchase such shares. The
disposition restrictions do not apply if a tender offer is made for all of the
outstanding New Michael Common Stock. In addition, the Michael Family
Shareholders are entitled during such two year period to certain registration
rights under the Securities Act with respect to the New Michael Common Stock
owned by them. Finally, during such two year period, the Michael Family
Shareholders will be entitled to designate two nominees for the Board of New
Michael (the "New Michael Board") if they collectively own ten percent or more
of the outstanding New Michael Common Stock and one nominee for director if
their ownership is below ten percent. The Michael Family Shareholders' initial
designees to the New Michael Board are Jeffrey J. Michael and Miles E. Efron.
See "THE REORGANIZATION -- Interest of Certain Persons in the Reorganization."
 
TREATMENT OF MICHAEL STOCK OPTIONS
 
   
     The Reorganization Agreement obligates New Michael to assume all existing
stock option plans of Michael and the stock award portion of Michael's Executive
Incentive Plan. Outstanding Michael stock options will be converted into options
to purchase New Michael Common Stock and, to the extent exercisable, may be
exercised at the stated exercise price and for an equal number of shares of New
Michael Common Stock. At         , 1996, Michael had granted options under these
Plans to purchase             shares, of which options for             shares
were currently exercisable. See "THE REORGANIZATION -- Effect
    
 
                                       14
<PAGE>   23
 
on Stock Option Plans." All outstanding stock options for NSU Common Stock will
be exercised or canceled prior to the Effective Time.
 
ACCOUNTING TREATMENT
 
     The Merger will be accounted for as a business combination utilizing the
reverse acquisition method with Michael being the accounting acquiror under
generally accepted accounting principles. As such, the Merger will be treated as
an acquisition using the purchase method of accounting with no change in the
recorded amount of Michael's assets and liabilities. The assets and liabilities
of NSU that are acquired as a result of the Merger will be recorded at their
fair market values. The ENStar assets and liabilities, following the
Distribution, will be recorded at their historic amounts as recorded in the
books and records of NSU. See "THE REORGANIZATION -- Accounting Treatment."
 
CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
     The obligations of Michael and NSU to consummate the Reorganization are
subject to the receipt of the following favorable rulings from the IRS:
 
      (i)  The Merger will be treated as a tax-free reorganization within the
           meaning of Section 368 of the Internal Revenue Code of 1986, as
           amended (the "Code"), and that no gain or loss will be recognized by
           any Michael stockholder upon receipt of New Michael Common Stock
           pursuant to the Merger.
 
      (ii) The Reverse Stock Split will not be treated as a stock distribution,
           or a transaction that has the effect of such a distribution, to which
           Sections 301, 305(b) or 305(c) of the Code apply. Accordingly, no
           taxable income will be recognized under such Sections by any of the
           shareholders of NSU, except for cash paid in lieu of fractional
           shares.
 
     (iii) The Distribution will qualify as a tax-free distribution under
           Sections 355 and 368(a)(1)(D) of the Code, and that no gain or loss
           will be recognized by any NSU shareholder upon the receipt of ENStar
           Common Stock pursuant to the Distribution (except upon the receipt of
           cash by an NSU shareholder in lieu of fractional shares of ENStar
           Common Stock).
 
     See "THE REORGANIZATION -- Certain Federal Income Tax Consequences."
 
REGULATORY APPROVALS
 
   
     The Merger is subject to the requirements of the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended (the "HSR Act"), and the rules
and regulations thereunder, which provide that certain transactions may not be
consummated until required information and materials are furnished to the
Antitrust Division of the Department of Justice and the Federal Trade Commission
("FTC") and the requisite waiting period has expired or is terminated. NSU and
Michael filed the required information and materials with the antitrust division
and the FTC effective May 16, 1996, and the requisite waiting period expired on
May 28, 1996. See "THE REORGANIZATION -- Regulatory Approvals."
    
 
   
DIFFERENCES IN RIGHTS OF MICHAEL STOCKHOLDERS.
    
 
   
     Upon consummation of the Merger, holders of Michael Common Stock will
become holders of the same number of shares of New Michael Common Stock. As a
result, their rights as stockholders, which are now governed by Delaware
corporate law and Michael's Certificate of Incorporation and Bylaws, will be
governed by Minnesota law and New Michael's Articles of Incorporation and
Bylaws. The principal differences between Delaware and Minnesota law and the
rights of stockholders and shareholders thereunder and between the rights of
stockholders of Michael under its Certificate of Incorporation and Bylaws and
shareholders of NSU under its Articles of Incorporation and Bylaws include
expanded appraisal rights under Minnesota law, more extensive anti-takeover
protection under Minnesota law and certain differences in the requirements for
calling special meetings of shareholders and taking shareholder and board action
without holding a meeting. For a summary of these and other differences between
the rights of holders of Michael Common Stock and New

<PAGE>   24
 
   
Michael Common Stock, see "COMPARISON OF RIGHTS OF STOCKHOLDERS AND
SHAREHOLDERS."
    
 
DISSENTERS' RIGHTS
 
   
     Holders of Michael Common Stock are not entitled to dissenters' or
appraisal rights in connection with the Reorganization. Holders of NSU Common
Stock who do not vote in favor of the Distribution and who file a written
objection thereto with NSU prior to the NSU Annual Meeting or at such meeting,
but before the vote is taken, and who have otherwise complied with Section
302A.473 of the MBCA will be entitled to certain dissenters' rights. See "THE
REORGANIZATION -- Dissenters' Rights." If holders of more than 1% of the
outstanding shares of NSU Common Stock exercise dissenters' rights, NSU has the
right under the Reorganization Agreement not to consummate the Reorganization.
    
 
COMPARATIVE MARKET PRICES AND DIVIDENDS
 
   
     Michael Common Stock is traded on the Nasdaq National Market under the
symbol MIKL. NSU Common Stock is traded on the Nasdaq National Market under the
symbol NSRU and the Pacific Stock Exchange under the symbol NSU. On December 20,
1995, the last full trading day preceding public announcement of the proposed
transactions, the closing price per share of Michael Common Stock reported by
the Nasdaq National Market was $10.88 and the closing price per share of NSU
Common Stock reported by the Nasdaq National Market was $6.00. On        , 1996,
the most recent practical date prior to the printing of this Proxy
Statement/Prospectus, the closing price per share of Michael Common Stock
reported by the Nasdaq National Market was $     and the closing price per share
of NSU Common Stock reported by the Nasdaq National Market was $     .
    
 
     The payment of future dividends on New Michael Common Stock will be a
business decision to be made by the New Michael Board from time to time based
upon the results of operations and the financial condition of New Michael and
such other factors as the New Michael Board considers relevant. See "COMPARATIVE
PER SHARE MARKET PRICE AND DIVIDEND INFORMATION."
 
     No market currently exists for the ENStar Common Stock. ENStar has applied
to have the ENStar Common Stock approved for quotation on the Nasdaq National
Market under the symbol "ENSR." No assurance can be given that an active market
will develop or continue for the ENStar Common Stock. Management of ENStar
currently intends to retain any earnings for use in its operations and does not
anticipate paying any cash dividends in the foreseeable future.
 
     New Michael expects to continue the Nasdaq National Market listing of NSU
Common Stock, but will use the symbol MIKL, rather than NSRU, and will
discontinue the listing of the New Michael Common Stock on the Pacific Stock
Exchange.

(1) These pro forma per share amounts represent the interest of a holder of a
    share of Michael Common Stock in New Michael after the Merger. The pro forma
    book value computation utilizes the book value of New Michael at March 31,
    1996 divided by the number of outstanding shares of New Michael Common Stock
    at March 31, 1996 reduced by 2,764,633 Retired Michael Shares. The pro forma
    net earnings

    computation for the year ended December 31, 1995, utilizes the net earnings
    of New Michael and the weighed average shares of Michael Common Stock
    reduced by 2,764,633 Retired Michael Shares. See "THE REORGANIZATION --
    Effects of the Reorganization" for a hypothetical calculation of such number
    of Retired Michael Shares.
    
 
(2) The calculation of pro forma dividends paid per share assumes the same per
    share dividend was paid.
 
   
(3) These pro forma per share amounts represent the interest of a holder of a
    share of NSU Common Stock in ENStar's per share book value at March 31, 1996
    and the net income from continuing operations after the Distribution for the
    year ended December 31, 1995. The book value per share and net income from
    continuing operations per share amounts represent the book value and net
    income from continuing operations, respectively, of ENStar divided by the
    number of outstanding shares of NSU Common Stock at March 31, 1996 for the
    book value computation and weighted average number of outstanding shares of
    NSU Common Stock for the year ended December 31, 1995 for the net income
    from continuing operations computation.
    
 
   
(4) These pro forma per share amounts represent the interest of a holder of a
    share of NSU Common Stock in New Michael per share book value at March 31,
    1996 and net income from continuing operations after the Merger for the year
    ended December 31, 1995. The pro forma book value computation is computed by
    dividing New Michael pro forma stockholder equity by the number of shares of
    outstanding New Michael Common Stock after reduction for the Retired Michael
    Shares (19,379,274, the historical outstanding shares of Michael at March
    31, 1996, less 2,764,633 Retired Michael Shares), this product is then
    adjusted for an assumed Reverse Stock Split ratio of .47 shares of New
    Michael Common Stock for every outstanding share of NSU Common Stock. The
    pro forma income from continuing operations computation is computed by
    dividing the New Michael pro forma net earnings for the year ended December
    31, 1995 by the New Michael weighted average shares outstanding (19,328,000,
    the historical weighted average shares of Michael Common Stock as of
    December 31, 1995, less 2,764,633 Retired Michael Shares), this product is
    then adjusted for an assumed Reverse Stock Split ratio of .48 shares of New
    Michael Common Stock for every outstanding share of NSU Common Stock. The
    Reverse Stock Split ratios differ in these computations due to the use of
    the actual number of shares outstanding for the book value computation and
    the weighted average shares outstanding for the net income from continuing
    operations computation.
    
 
(5) The pro forma combined amounts are the total of the ENStar and the New
    Michael pro forma per share amounts.

     In addition to the other information contained in or incorporated by
reference into this Proxy Statement/Prospectus, NSU's shareholders should
consider the following risk factors regarding ENStar and the ENStar Common Stock
that such shareholders will receive in the Distribution. All references herein
to ENStar are intended to include the operating unit of NSU that will be
transferred to ENStar in connection with the Distribution.
 
LIMITED HISTORY OF PROFITABILITY; UNCERTAINTY OF FUTURE RESULTS
 
     ENStar has a limited history of profitability. ENStar experienced operating
losses during 1991, 1992, 1993 and 1994. During 1995, ENStar generated operating
income of approximately $1 million. Americable derives its revenues from three
primary lines of business: networking products and services, cable and
connectivity products and cable assemblies. Americable has recently increased
the focus of its business on network services and its cable assembly business,
which are generally more profitable. No assurance can be made, however, that
Americable will be successful in increasing revenues from its network services
and its cable assemblies. In addition, Americable continues to make significant
investments in new sales, engineering and technical personnel.
 
     Transition's ability to maintain its present level of sales and its
historical sales growth is highly dependent upon its ability to offer new
products that meet customer's demands in a rapidly changing market, particularly
in light of the relatively short life cycle of its products. In order to achieve
market acceptance of new products, Transition plans to continue its investment
in research and development expenses. Transition had research and development
expenses of approximately $1,440,000 in 1995. There can be no assurance,
however, that its research and development efforts will result in commercially
successful new products in the future. In addition, Transition believes that
sales and marketing expenses will continue to increase in terms of absolute
dollars in an effort to differentiate its products and enhance its competitive
position.
 
     These anticipated increases in operating expenses at both Americable and
Transition may result in lower operating profit at ENStar, if the companies are
unable to maintain their respective current gross profit margins and continued
sales growth. Further, if Americable is not successful in generating higher
volumes of service revenues, its operating margins will decline and its ability
to maintain its current operating profitability could be materially adversely
affected. Based on the above factors, there can be no assurance that ENStar will
be able to increase or sustain its profitability on a quarterly or annual basis
in the future.
 
PRODUCT AND SERVICE DEVELOPMENT RISKS
 
     With respect to Transition, the market for networking products is subject
to rapid technological change, evolving industry standards and frequent new
product introductions and, therefore, requires a high level of expenditures for
research and development. Transition may be required to incur significant
expenditures to develop such product offerings. There can be no assurance that
Transition will be successful in identifying, sourcing, developing and marketing
product enhancements or new products that respond to this rapidly changing
market. Also, there can be no assurance that its product enhancements and new
products will adequately meet the requirements of the marketplace and achieve
market acceptance. A critical factor in market acceptance of product
enhancements and new products is the timely introduction of such products and
enhancements in order to take advantage of existing market opportunities.
Transition has, in the past, experienced delays in the introduction of certain
of its new products and enhancements.
 
     The markets for Americable's products and services are also characterized
by rapidly changing technology and frequent new product and service offerings by
its competitors. The introduction of new technologies can render existing
products and services obsolete or unmarketable. Americable's continued success
will depend on its ability to enhance existing products and services and to
develop and introduce, on a timely and cost-effective basis, new products and
services that keep pace with technological developments and address increasingly
sophisticated customer requirements.
 
                                       21
<PAGE>   30
 
     ENStar's business, financial condition and results of operations could be
materially adversely affected if Transition were to incur delays in developing
or introducing new products or product enhancements or if such new products or
product enhancements did not gain market acceptance or in the event that
Americable were to incur delays in sourcing and developing new products and
services or that these products and services would achieve market acceptance.
 
EXPANSION STRATEGY
 
     ENStar's expansion strategy includes both internal growth and the
identification and pursuit of acquisition opportunities at Americable.
Americable currently operates in six locations and the success and the rate of
Americable's expansion into new geographical markets will depend on a number of
factors, including general economic and business conditions affecting the
industries of Americable's customers in such markets, competition, the
availability of sufficient capital, the availability of sufficient inventory to
meet customer demand, and the ability to attract and retain qualified personnel
and operate effectively in geographic areas in which Americable has no prior
experience. As a result, there can be no assurance that Americable will be able
to achieve its planned expansion on a timely or profitable basis.
 
     With respect to Americable's identification and pursuit of acquisition
opportunities, viable acquisition candidates may not be available or not
available on terms acceptable to Americable. Furthermore, Americable has not
engaged in any significant acquisitions recently, and no assurance can be made
that Americable will be able to successfully acquire or integrate the operations
of another business into the operations and business of Americable. Americable
has no present commitments, agreements or understandings with respect to any
acquisitions.
 
     If Americable continues to grow, it may be required to make further
investments in personnel and information technology systems. Failure to
successfully hire or retain such personnel or implement such systems could have
a material adverse effect on ENStar's results of operations and financial
condition. There can be no assurance that Americable will be able to manage its
expanding operations effectively, that it will be able to maintain or accelerate
its recent growth or that Americable will be able to continue to operate
profitably.
 
FLUCTUATIONS IN QUARTERLY RESULTS
 
     ENStar's quarterly revenues and operating results have varied significantly
in the past and will likely continue to do so in the future. Quarterly revenues
and operating results may fluctuate as a result of the demand for Americable's
and Transition's products and services, the introduction of new hardware and
software technologies offering improved features, the introduction of new
products and services by competitors, changes in the level of operating
expenses, competitive conditions and economic conditions generally.
 
     At Americable, the purchase of its products and services generally involves
a significant commitment of capital, with the delays frequently associated with
large capital expenditures and required authorization procedures within an
organization. For these and other reasons, Americable's operating risks are
subject to a number of risks over which it has little or no control, including
customers' technology life cycle needs, budgetary constraints and internal
authorization reviews. Further, Americable is increasing its operating expenses,
including an increase in personnel, based on anticipated revenue growth in its
networking line of business.
 
     A variety of factors may cause period-to-period fluctuations in the
operating results of Transition. Such factors include, but are not limited to,
product mix, competitive pricing pressures, material costs and timely
availability, revenue and expenses related to new product introductions, as well
as delays in customer purchases in anticipation of new products or enhancements
by Transition or its competitors. Further, Transition plans to continue to
invest in research and development, sales and marketing and technical support
staff.
 
     ENStar's operating results could be adversely affected if it is unable to
adjust spending sufficiently in a timely manner to compensate for any unexpected
revenue shortfall. Accordingly, ENStar believes that period-to-period
comparisons of its operating results should not be relied upon as an indication
of future performance.
 
                                       22
<PAGE>   31
 
In addition, the results of any quarterly period are not indicative of results
to be expected for a full fiscal year. It is possible that in certain future
quarters, ENStar's operating results may be below the expectations of public
market analysts and investors. In such event, the price of ENStar's Common Stock
would likely be materially adversely affected.
 
DEPENDENCE ON AND NEED TO RECRUIT AND RETAIN KEY PERSONNEL
 
     ENStar's success depends to a significant extent on its ability to attract
and retain key personnel. In particular, Americable and Transition are dependent
on their respective engineering and technical personnel. Competition for such
technical personnel is intense and no assurance can be given that ENStar will be
able to recruit and to retain such personnel. The failure to recruit and to
retain management and technical personnel could have a material adverse effect
on ENStar's anticipated growth, revenues and results of operations.
 
CONCENTRATION OF REVENUES
 
   
     During 1995 and the first quarter of 1996, one customer accounted for
approximately 11% and 17%, respectively, of Americable's net sales, and a
different customer accounted for approximately 9% and 15%, respectively, of net
sales. No other customers accounted for more than 10% of Americable's revenues.
In addition, Americable derived approximately 61% of its revenues from its 100
largest customers in 1995, and 70% of its revenues from its 100 largest
customers in the first quarter of 1996. While Americable seeks to build
long-term customer relationships, revenues from any particular customer can
fluctuate from period to period due to such customer's purchasing patterns.
    
 
   
     Transition distributes its products through an expanding network of
reseller channels, which include a number of regionally based domestic and
international volume distributors and, to a lesser extent, value added
resellers. In 1995 and the first quarter of 1996, Americable was Transition's
largest domestic customer accounting for approximately 14% and 16%,
respectively, of domestic net sales (9% and 10%, respectively, overall). During
1995 and the first quarter of 1996, Transition's largest international customer
accounted for approximately 11% and 12%, respectively, of international net
sales (4% and 5%, respectively, overall). Moreover, the ten distributors that
sold the largest amount of Transition's products accounted for approximately 39%
and 43%, respectively, of Transition's net sales for 1995 and the first quarter
of 1996.
    
 
     Any termination or significant disruption of the companies' relationships
with a number of its principal customers could have a material adverse effect on
ENStar's business, financial condition and results of operations. In addition, a
deterioration in the financial condition of any of its principal customers could
expose ENStar to the possibility of large accounts receivable write-offs, which
would adversely affect ENStar's financial condition and results of operations.
 
DEPENDENCE ON KEY SUPPLIERS AND PRODUCT SUPPLY
 
     The networking industry has experienced product supply shortages and
customer order backlogs due to the inability of certain manufacturers to supply
certain products on a timely basis. In addition, certain suppliers have
initiated new channels of distribution that increase competition for the
available product supply. There can be no assurance that suppliers will be able
to maintain an adequate supply of products to fulfill Americable's and
Transition's customer orders on a timely basis. Both Americable and Transition
have experienced product supply shortages in the past and expect to experience
such shortages from time to time in the future. Failure to obtain adequate
product supplies or fulfill customer orders on a timely basis could have a
material adverse effect on ENStar's business, financial condition, and results
of operations.
 
     A significant portion of Americable's revenues is derived from sales of
network hardware, including products of various major suppliers. During 1995
approximately 19% of the Americable's sales represented products manufactured by
Bay Networks, Inc. ("Bay Networks"). Americable's agreements with those
suppliers from which it purchases products directly generally contain provisions
for periodic renewals and for termination by the supplier without cause,
generally upon relatively short notice. Although Americable believes its
supplier relationships are good, there can be no assurance that Americable's
relationships will continue as presently in effect. The loss of a major
supplier, the deterioration of Americable's relationship with a major supplier
or the failure of Americable to establish good relationships with major new
suppliers as they develop could have a material adverse effect on ENStar's
business.
 
                                       23
<PAGE>   32
 
INVENTORY MANAGEMENT
 
     The networking industry is characterized by rapid product improvement and
technological change resulting in relatively short product life cycles and rapid
product obsolescence, which can place inventory at considerable valuation risk.
Some of Transition's products include components that are currently available
from limited sources and require long order lead times. Because of the long lead
times along with Transition's desire to be responsive to customer demand,
Transition has maintained higher inventory levels compared to other networking
manufacturers. Due to the ongoing risk of product obsolescence and changes in
customer demand, there can be no assurances that Transition will be able to
successfully manage its existing and future inventories.
 
     Although it is industry practice for Americable's suppliers to provide
price protection to Americable intended to reduce the risk of inventory
devaluation, such policies are subject to change. Americable also has the option
of returning, subject to certain limitations, a percentage of its current
product inventories each quarter to certain manufacturers as it assesses each
product's current and forecasted demand. The amount of inventory that can be
returned to suppliers varies under Americable's agreements and such return
policies may provide only limited protection against excess inventory. There can
be no assurance that suppliers will continue such policies, that unforeseen new
product developments will not affect Americable adversely or that Americable can
successfully manage its existing and future inventories. Any inventory
adjustments could adversely affect ENStar's financial condition and results of
operations.
 
COMPETITION
 
     Each of ENStar's businesses face substantial competition from a large
number of companies, some of which are larger, have greater financial resources,
broader name recognition and, in many cases, lower product and operating costs
than ENStar.
 
     The industry in which Transition operates is highly competitive, and
Transition believes that such competition will continue to intensify. The
industry is characterized by rapid technological change, short product
life-cycles, frequent product introductions and evolving industry standards.
Transition competes with a number of independent companies focused on the LAN
market, including companies with significantly greater financial resources, more
extensive business experience, and greater market and service capabilities than
Transition. There can be no assurance that ENStar will be able to compete
successfully.
 
     ENStar expects to face further competition from new market entrants and
possible alliances between competitors in the future. Certain of ENStar's
current and potential competitors have greater financial, technical, marketing
and other resources than ENStar. As a result, they may be able to respond more
quickly to new or emerging technologies and changes in customer requirements or
to devote greater resources to the development, promotion and sale of their
products and services than ENStar. No assurance can be given that ENStar will be
able to compete successfully against current and future competitors. See
"BUSINESS OF ENStar -- Competition."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
     Sales of a substantial number of shares of ENStar Common Stock in the
public market following the Distribution could adversely affect the market price
for the ENStar Common Stock. Upon consummation of the Reorganization the Michael
Family Shareholders, in the aggregate, will beneficially own approximately
1,895,000 shares, or approximately 60%, of the outstanding ENStar Common Stock.
 
ABSENCE OF PRIOR PUBLIC MARKET AND POSSIBLE VOLATILITY OF STOCK PRICE
 
     Prior to this offering, there has been no public market for the ENStar
Common Stock. There can be no assurance that, following this offering, an active
trading market for the ENStar Common Stock will develop or be sustained,
particularly in light of the limited number of shares being distributed in the
Distribution. The market price of the ENStar Common Stock could be subject to
significant fluctuations in response to variations in quarterly operating
results, changes in the market value of its CorVel investment, changes in
 
                                       24
<PAGE>   33
 
earnings estimates by analysts, general conditions in the industries in which
ENStar's customers compete and other events or factors. In addition, the stock
market, from time to time, has experienced extreme price and volume fluctuations
which have particularly affected the market price for companies in ENStar's and
CorVel's industries, and which have often been unrelated to the operating
performance of such companies. These broad fluctuations may adversely affect the
market price of the ENStar Common Stock.
 
POSSIBLE VOLATILITY OF CORVEL STOCK PRICE
 
   
     CorVel, in its reports and other information prepared and filed by it with
the Commission, has indicated that the market price of the CorVel Common Stock
may be highly volatile. CorVel has also indicated that factors such as
variations in CorVel's revenues, earnings and cash flow, general market trends
in the workers' compensation managed care market, and announcements of
innovations by CorVel or its competitors could cause the market price of the
CorVel Common Stock to fluctuate substantially. Specifically, CorVel has
reported that the quarter to quarter percentage growth in operating results for
CorVel's three most recently completed fiscal quarters was lower than the growth
rates historically experienced by CorVel. CorVel's slower growth rate in those
three fiscal quarters was partially attributable to a reduction in the growth
rate of health care expenditures nationally, contributing to a reduction in the
growth rate of claims processed by CorVel. There can be no assurance that
CorVel's growth rate in the future, if any, will be at or near historical
levels. In addition, the stock market has in the past experienced price and
volume fluctuations that have particularly affected companies in the health care
and managed care markets resulting in changes in the market price of the stock
of many companies which may not have been directly related to the operating
performance of those companies. Such broad market fluctuations may adversely
affect the market price of the CorVel Common Stock, which in turn may adversely
affect the market price of the ENStar Common Stock.
    
 
CERTAIN RISKS PERTAINING TO THE CORVEL COMMON STOCK
 
     CorVel, in its reports and other information prepared and filed by it with
the Commission, has indicated that an investment in the CorVel Common Stock
involves a high degree of risk, including the potential adverse impact of
government regulations, possible litigation and legal liability, competition,
changes in market dynamics, dependence on key personnel and risks related to
CorVel's growth strategy. These risks are described in more detail in the
reports and other information prepared and filed by CorVel with the Commission.

<PAGE>   35
 
   
     THE NSU BOARD UNANIMOUSLY RECOMMENDS THAT HOLDERS OF NSU COMMON STOCK VOTE
FOR EACH OF THE NSU PROPOSALS AND FOR EACH OF THE NOMINEES FOR ELECTION TO THE
BOARD OF DIRECTORS OF NSU.
    
 
PROXIES
 
     Michael. Votes cast by proxy or in person at the Michael Annual Meeting
will be tabulated by the election inspector appointed for the meeting. All
shares of Michael Common Stock represented by properly executed proxies received
prior to or at the Michael Meeting and not revoked will be voted in accordance
with the instructions indicated in such proxies. If no instructions are
indicated on a properly executed returned proxy, such proxy will be voted FOR
the Michael Proposal. A properly executed proxy marked "ABSTAIN" (or a proxy
marked "withhold vote for" as to the election of directors), although counted
for purposes of determining whether there is a quorum, will not be voted.
Accordingly, since the affirmative vote of a majority of the shares of Michael
Common Stock on the Michael Record Date represented in person or by proxy and
entitled to vote is required for approval of the Michael Proposal, a properly
executed proxy marked "ABSTAIN" will have the effect of a vote against the
Michael Proposal. If a broker indicates on a proxy that it does not have
discretionary authority as to certain shares to vote on a particular matter,
those shares will not be considered as present and entitled to vote with respect
to that matter.
 
     NSU. Votes cast by proxy or in person at the NSU Annual Meeting will be
tabulated by the election inspector appointed for the meeting. All shares of NSU
Common Stock represented by properly executed proxies received prior to or at
the NSU Meeting and not revoked will be voted in accordance with the
instructions indicated in such proxies. If no instructions are indicated on a
properly executed returned proxy, such proxy will be voted FOR the NSU
Proposals. A properly executed proxy marked "ABSTAIN" (or a proxy marked
"withhold vote for" as to the election of directors), although counted for
purposes of determining whether there is a quorum, will not be voted.
Accordingly, since the affirmative vote of a majority of the shares of NSU
Common Stock outstanding on the NSU Record Date, represented in person or by
proxy and entitled to vote, is required for approval of each of the NSU
Proposals, a properly executed proxy marked "ABSTAIN" with respect to any such
proposal will have the effect of a vote against such proposal. If a broker
indicates on the proxy that it does not have discretionary authority as to
certain shares to vote on a particular matter, those shares will not be
considered as present and entitled to vote with respect that matter.
 
     It is not expected that any matter not referred to herein will be presented
for action at the Michael and NSU Annual Meetings. If any other matters are
properly brought before the Michael Annual Meeting or the NSU Annual Meeting,
the persons named in the proxies will have discretion to vote on such matters in
accordance with their best judgment. However, shares represented by proxies that
have been voted "AGAINST" the Michael Proposal, or any of the NSU Proposals, as
the case may be, will not be used to vote "FOR" postponement or adjournment of
the Michael Annual Meeting or the NSU Annual Meeting, as the case may be, for
the purpose of allowing additional time for soliciting additional votes "FOR"
the Michael Proposal or the NSU Proposals, as the case may be. The grant of a
proxy will also confer discretionary authority on the persons named in the proxy
as proxy appointees to vote in accordance with their best judgment on matters
incident to the conduct of the Annual Meetings, including (except as stated in
the preceding sentence) adjournment for the purpose of soliciting additional
votes.
 
   
     Revocation of Proxies. A stockholder or shareholder giving a proxy may
revoke it at any time prior to the voting of the proxy by filing with the
secretary of Michael or NSU, as the case may be, a written notice of revocation
or another proxy bearing a later date. Unless otherwise noted on the proxy, the
proxies will vote FOR the proposals set forth herein. Any written notice of
revocation or subsequently dated Michael proxy should be mailed or delivered to
Michael Foods, Inc., 324 Park National Bank Building, 5353 Wayzata Boulevard,
Minneapolis, Minnesota 55416; Attention: Secretary. Any written notice of
revocation or subsequently dated NSU proxy should be mailed or delivered to
North Star Universal, Inc., 6479 City West Parkway, Eden Prairie, MN 55344,
Attention: Secretary. A stockholder or shareholder may also revoke his or her
proxy by attending the Michael Annual Meeting or the NSU Annual Meeting and
voting in person. Attendance at the Michael Annual Meeting or the NSU Annual
Meeting will not in itself constitute the revocation of a proxy.

     Solicitation of Proxies. Each party will bear its own costs with respect to
the Annual Meetings including the cost of preparing, assembling and mailing the
Notice of Annual Meeting, this Proxy Statement/ Prospectus and the form of
proxy, including the reimbursement of banks, brokers and other nominees for
forwarding proxy materials to beneficial owners. Proxies may also be solicited
personally or by telephone by directors, officers and regular employees of
Michael or NSU who will receive no additional compensation.
 
     THE MATTERS TO BE CONSIDERED AT THE MICHAEL AND NSU ANNUAL MEETINGS ARE OF
IMPORTANCE TO THE MICHAEL STOCKHOLDERS AND THE NSU SHAREHOLDERS. ACCORDINGLY,
MICHAEL STOCKHOLDERS AND NSU SHAREHOLDERS ARE URGED TO READ AND CAREFULLY

              PROPOSAL NUMBER ONE: APPROVAL OF THE REORGANIZATION
                            AGREEMENT AND THE MERGER
            PROPOSAL NUMBER TWO: APPROVAL OF THE REVERSE STOCK SPLIT
              PROPOSAL NUMBER THREE: APPROVAL OF THE DISTRIBUTION
 
                               THE REORGANIZATION
 
     The following information describes certain aspects of the Reorganization.
This description does not purport to be complete and is qualified in its
entirety by reference to the Appendices hereto, including the Reorganization
Agreement and the exhibits thereto, which are attached to this Proxy
Statement/Prospectus as Appendix I and are incorporated herein by reference. All
shareholders are urged to read Appendix I in its entirety. See also "THE
REORGANIZATION AGREEMENT."
 
EFFECTS OF THE REORGANIZATION
 
   
     Prior to the consummation of the Merger, NSU will contribute all of its
assets and liabilities other than certain indebtedness and other agreed upon
assets and liabilities to ENStar. See "THE REORGANIZATION AGREEMENT -- Effects
of the Reorganization on the Stockholders of Michael and the Shareholders of
NSU." Upon consummation of the Reorganization on the Effective Date of the
Merger: (i) Merger Co. will be merged with and into Michael and Michael will
become a wholly-owned subsidiary of NSU; (ii) each stockholder of Michael (other
than NSU) will receive, in exchange for each share of Michael Common Stock held
by such stockholder, one share of New Michael Common Stock; (iii) each share of
Michael Common Stock held by NSU will be canceled and retired; (iv) NSU will
change its name to Michael Foods, Inc. and will continue the business previously
conducted by Michael; (v) NSU will effectuate the Reverse Stock Split; and (vi)
NSU will effectuate the Distribution, whereby all of the outstanding ENStar
Common Stock will be distributed pro rata to the shareholders of NSU of record
as of a record date just prior to the Effective Date of the Merger.
    
 
   
     As part of the negotiations with respect to the structure of the
Reorganization, Michael requested that, in order to avoid confusion on the part
of holders of Michael Common Stock, in the Merger each holder of Michael Common
Stock would receive one share of NSU Common Stock in exchange for each share of
Michael Common Stock held by such stockholder. In order to accommodate this
request, the Reorganization was structured so that the number of outstanding
shares of NSU Common Stock would be reduced through the Reverse Stock Split. In
the Reverse Stock Split, each outstanding share of NSU Common Stock will be
converted into a fraction of one share of New Michael Common Stock determined by
multiplying each such share by a fraction where the denominator is the number of
outstanding shares of NSU Common Stock immediately prior to the Effective Date
and the numerator is the number of shares of Michael Common Stock owned by NSU
at such date less the number of shares of Michael Common Stock owned by NSU
which are retired in consideration for the Net Indebtedness retained by New
Michael. For purposes of the Reorganization Agreement, Net Indebtedness is
defined to be the amount of outstanding NSU subordinated debentures and
subordinated fixed-term or extendible time certificates and the Dissenting
Shares Holdback, less any cash retained by NSU at the time of the Merger. Under
the terms of the Reorganization Agreement, NSU has indicated to Michael that the
Net Indebtedness retained by NSU, excluding the Dissenting Shares Holdback,
effectively retired as a result of the Reorganization may not be less than $25
million nor more than $29 million. The number of shares of Michael Common Stock
to be retired (the "Retired Michael Shares") in consideration for the Net
Indebtedness will be determined by dividing the amount of Net Indebtedness by
the average market price of the Michael Common Stock for the twenty trading days
ending on the third trading day prior to the Effective Date of the Merger (the
"Average Price of Michael Common Stock") after applying a certain percentage
discount to the Average Price of Michael Common Stock (the "Discount Factor").
The Discount Factor will be based upon the amount of Net Indebtedness, ranging
from .92 at $25 million to .91 beginning at $28.75 million, resulting in an
effective discount of 8% to 9%, respectively. See "THE REORGANIZATION AGREEMENT
- -- Effects of the Reorganization on the Stockholders of Michael and the
Shareholders of NSU."

     Under the hypothetical example provided above, in the Reverse Stock Split
each share of NSU Common Stock issued and outstanding immediately prior to the
Effective Time would be converted into .47 shares of New Michael Common Stock.
    
 
   
     Pursuant to the Reorganization Agreement, NSU has indicated that the amount
of Net Indebtedness that New Michael will be required to assume, excluding the
Dissenting Shares Holdback, will be between $25 million and $29 million. NSU has
also otherwise indicated that it intends to retain cash in an amount at least
equal to the Dissenting Shares Holdback such that the Net Indebtedness will be
between $25 million and $29 million. At this range of Net Indebtedness, the
relevant discount factors are .92 (a discount of 8%) if Net Indebtedness is $25
million and .91 (a discount of 9%) if Net Indebtedness is $29 million. Assuming
the Average Price of Michael Common Stock is $11.00 or $17.00, the minimum and

EFFECTIVE TIME
 
     If the Michael Proposal is approved and adopted by the requisite vote of
the stockholders of Michael, the NSU Proposals are approved and adopted by the
requisite vote of the shareholders of NSU and the other conditions to the
Reorganization are satisfied (or waived to the extent permitted), the Merger
will be consummated and effected at the time a Certificate of Merger is filed
with the Secretary of State of the State of Delaware.
 
     The Reorganization Agreement provides that NSU and Michael will cause the
Effective Date to occur as promptly as practicable, but in no event later than
ten business days after the approval and adoption of the Michael Proposal by the
requisite vote of the stockholders of Michael, the approval and adoption of the
NSU Proposals by the requisite vote of the shareholders of NSU and satisfaction
(or waiver, to the extent permitted) of the other conditions contained in the
Reorganization Agreement. The Reorganization Agreement may be terminated by
either NSU or Michael in certain circumstances, notwithstanding the prior
approval and adoption of the Reorganization Agreement by their respective
shareholders and stockholders. See "THE REORGANIZATION AGREEMENT --
Termination."
 
BACKGROUND OF THE REORGANIZATION
 
     In March 1987, NSU formed Michael to consolidate and focus development of
NSU's food businesses, and shortly thereafter Michael completed an initial
public offering of approximately 36% of its outstanding common stock. Since that
time, NSU's ownership of Michael has been reduced from approximately 64% to
approximately 38% of the outstanding Michael Common Stock through sales by NSU
of Michael Common Stock and additional issuances of Michael Common Stock.
 
     For many years, both before and after the initial public offering of
Michael's Common Stock, NSU raised funds to finance acquisitions and support its
operations by offering and selling subordinated debentures and subordinated
fixed-term and extendible time certificates to the public. Debt service for this
indebtedness was provided through the reinvestment of maturing obligations by
investors, sales of assets and cash flow generated from NSU's operating
subsidiaries. Since the initial public offering of Michael in 1987, however, NSU
has not had the use of cash flow generated by Michael's operations other than
quarterly Michael dividends. Also, in June 1991, CorVel, formerly a wholly owned
subsidiary of NSU, completed an initial public offering of its common stock.
After the CorVel initial public offering, NSU ceased to have the use of cash
flow generated by CorVel. CorVel has not paid dividends on its common stock in
the past.
 
     As a result of these transactions, NSU has experienced cash flow deficits
from operations, which has resulted in greater reliance by NSU on the sale of
subordinated fixed-term and extendible time certificates to finance continuing
operations and service its indebtedness. In response to this situation, NSU's
senior
 
                                       31
<PAGE>   40
 
management has, for many years, considered various alternative strategies and
transactions to substantially reduce the amount of NSU's indebtedness and to
permit its shareholders to realize the substantial value of NSU's interest in
Michael. One obvious strategic alternative has always been to participate in a
tax-advantaged transaction involving Michael.
 
     From time to time since 1990, NSU and Michael senior management have had
discussions concerning various possible tax-advantaged transactions that would
result in all or a portion of NSU's substantial ownership interest in Michael
being held directly by NSU's shareholders. Also, certain of the transactions
discussed involved the assumption of some or all of NSU's outstanding
indebtedness in consideration of the retirement of some of the Michael Common
Stock held by NSU. Although a number of alternative transactions and transaction
structures were discussed, agreement was never reached on any particular
transaction, transaction structure or related financial terms and none of these
discussions progressed beyond the preliminary discussion stage.
 
   
     In the summer of 1994, Jeffrey J. Michael, President and Chief Executive
Officer of NSU, contacted Gregg A. Ostrander, President and Chief Executive
Officer of Michael, to request that Michael and NSU hold discussions again in an
effort to structure a mutually acceptable transaction that would provide for the
assumption by Michael of some or all of NSU's outstanding indebtedness and
permit NSU's shareholders to directly own NSU's interest in Michael. A number of
meetings between senior management of both companies followed in the fall of
1994, and continued off and on through the spring of 1995. During this time the
fundamental elements required by each of NSU and Michael in any such transaction
between them were discussed. These elements included the following: (i) any such
transaction could not result in federal income tax to the parties or their
respective shareholders or stockholders; (ii) the amount of NSU indebtedness
assumed by Michael in any such transaction had to be within parameters to be
agreed upon; (iii) the Michael Common Stock to be retired in consideration for
the debt assumed in any such transaction had to be valued at a discount to the
market; and (iv) Michael had to be protected from the liabilities of NSU
relating to the operations of NSU (other than its investment in Michael Common
Stock). Michael and its financial advisors also concluded that the transfer of
all other assets and liabilities of NSU to a separate company to be spun-off to
the NSU shareholders or some other disposition of such assets and satisfaction
of such liabilities was necessary in order to avoid higher costs of capital that
would otherwise occur if such assets and liabilities were retained after the
Reorganization and to avoid the adverse impact on the value of Michael Common
Stock if New Michael were engaged in businesses unrelated to its core food
processing and distribution businesses. As a result of these discussions, senior
management of both companies, with the assistance of their respective tax and
legal advisors, developed a general transaction structure proposal that
satisfied the parties' fundamental requirements. No agreement was reached,
however, on the financial terms, or on certain of the other terms of this
proposal.
    
 
     Once a potentially acceptable transaction structure proposal had been
developed, advisors of both companies were directed to obtain a preliminary
indication from the IRS as to the tax treatment of the proposal. Discussions
with the IRS occurred during the spring and summer of 1995, which led senior
management of both companies to conclude that there were reasonable prospects
for receipt of a favorable ruling concerning the tax-free nature of the
transaction structure proposal.
 
   
     Following the discussions with the IRS, NSU retained its financial advisor,
GAHS, in July 1995. Michael had previously engaged its financial advisor, Piper
Jaffray, in April 1995.
    
 
     Beginning in September 1995, NSU and Michael began meetings involving
senior management and their respective legal, tax and financial advisors to
discuss the financial and other terms relating to the transaction structure
proposal that had been developed and discussed with the IRS. These discussions
continued in October, during which tentative agreement was reached between the
senior managements of NSU and Michael as to certain of the principal terms of
the transaction proposal. On October 27, 1995, immediately following Michael's
regular quarterly board meeting, Michael's management informed the Michael Board
of the status of negotiations with NSU and the principal terms of the
transaction proposal that was currently under consideration by Michael senior
management. Messrs. Jeffrey J. Michael, James H. Michael and Miles E. Efron,
each a member of the board of directors of both NSU and Michael, at the request
of Michael,
 
                                       32
<PAGE>   41
 
did not participate in this discussion. At the NSU Board meeting held on
November 7, 1995, NSU's management and its financial advisor discussed with the
NSU Board the principal terms of the transaction proposal that was currently
under consideration by NSU senior management. The NSU Board, after such
discussion, directed and authorized certain officers of NSU to negotiate the
terms of a definitive agreement with respect to the transaction proposed,
subject to final board review and approval.
 
   
     The transaction proposal presented to each of the Michael and NSU Boards at
their respective meetings in late October and early November included a range of
permitted Net Indebtedness of between $25 million and $38 million and a
corresponding range of Discount Factors of between .92 and .90 (an effective
discount of 8% to 10%), depending on the amount of Net Indebtedness at the time
of the Merger. This range of Net Indebtedness was negotiated by the parties
because NSU desired as much flexibility as possible in fixing the amount of Net
Indebtedness depending upon the market price of the Michael Common Stock
immediately prior to the Merger and whether NSU would be able to sell certain of
its assets for fair value prior to the Effective Date of the Reorganization.
Michael also insisted on a range of Net Indebtedness in order that the stock
repurchase would be accretive to Michael's pro forma earnings per share and that
replacement financing could be obtained under existing credit arrangements at
substantially the same financing costs to Michael. The maximum permitted amount
of Net Indebtedness was negotiated based on the amount of NSU's Net Indebtedness
at the time the Reorganization Agreement was executed, which was approximately
$38 million. For the reasons described above, Michael insisted upon a minimum
amount of Net Indebtedness of $25 million.
    
 
   
     Also, as described above, one of the fundamental elements required by
Michael in any transaction with NSU was that the Michael Common Stock to be
repurchased in the transaction be valued at a discount to the market. The
determination of the amount of the Discount Factor based on the amount of Net
Indebtedness of NSU at the time the Merger was negotiated by the parties. The
increase in the effective discount as the amount of Net Indebtedness increases
was required by Michael because of Michael's view that it would cost more for
New Michael to refinance such indebtedness. In negotiating the Discount Factor,
both parties reviewed comparable stock repurchase transactions and found that
the effective discount negotiated by the parties was within the range of
discounts that had been negotiated by other issuers in repurchase transactions.
    
 
   
     Over the next several weeks, the terms of the definitive agreement were
negotiated and a definitive agreement was presented to each of the NSU and
Michael Boards at separate meetings held on December 21, 1995. Messrs. Michael,
Michael and Efron recused themselves from participation in the meeting of the
Michael Board. The Boards of Directors of NSU and Michael approved the
Reorganization Agreement at their respective meetings held on that date at which
meetings each of the Boards of Michael and NSU received the opinion of their
respective financial advisor as to the fairness of the transactions contemplated
by the Reorganization Agreement. The Reorganization Agreement was executed by
NSU and Michael later that same day.
    
 
   
     As required pursuant to the terms of the Reorganization Agreement, NSU has
notified Michael that the Net Indebtedness, less the amount of cash retained by
NSU and excluding the Dissenting Shares Holdback, will be between $25 million
and $29 million. The corresponding Discount Factor will be between .92 and .91.
NSU has also otherwise indicated that it intends to retain cash in an amount at
least equal to the Dissenting Shares Holdback such that the Net Indebtedness
will be between $25 million and $29 million.
    
 
RECOMMENDATION OF MICHAEL BOARD; MICHAEL'S REASONS FOR THE REORGANIZATION
 
     THE MICHAEL BOARD UNANIMOUSLY RECOMMENDS THAT HOLDERS OF MICHAEL COMMON
STOCK VOTE FOR THE MICHAEL PROPOSAL.
 
   
     Michael's Reasons for the Transactions. On December 21, 1995, the Michael
Board met to consider the Merger and the transactions contemplated thereby.
Michael's senior management, Michael's legal and accounting advisors and Piper
Jaffray, its investment banker, made presentations to the Michael Board and
discussed with the Michael Board their views and analyses of various aspects of
the proposed transactions. Michael's legal advisors reviewed with the Michael
Board the principal terms of the Reorganization Agreement and ancillary
agreements, the procedures to be followed in considering and adopting the
    
 
                                       33
<PAGE>   42
 
   
Reorganization Agreement and the principal conditions to its completion.
Michael's auditors reviewed the tax and accounting consequences of the
Reorganization to Michael and its stockholders and, in particular, the
procedures for the tax ruling request. Piper Jaffray then reviewed its fairness
opinion and supporting documentation. The Michael Board reviewed and considered,
among other things, the background of the proposed Reorganization, the
alternative of NSU remaining a Michael stockholder until it was compelled or
chose to sell or otherwise dispose of its block of Michael Common Stock,
financial and valuation analyses of the Reorganization, the terms of the
Reorganization and the other matters described herein. The Michael Board
reviewed and considered, among other things, the background of the proposed
transaction, Michael's strategic alternatives, financial and valuation analyses
of the transaction, the terms of the Reorganization and the other matters
described herein. Piper Jaffray gave an opinion that, based upon the matters
presented to the Michael Board and as set forth in its opinion, as of such date,
the consideration paid by Michael in the form of Net Indebtedness retained by
New Michael for the Retired Michael Shares and the exchange of Michael Common
Stock for New Michael Common Stock is fair to Michael from a financial point of
view. See "-- Fairness Opinions."
    
 
   
     In view of the variety of factors considered in connection with its
evaluation of the Reorganization, the Michael Board did not quantify or
otherwise attempt to assign relative weights to the specific factors considered
in reaching its determination. In reaching its determination to recommend
approval of the transactions, the Michael Board consulted with Michael
management, as well as legal counsel, accounting and tax advisors, and its
investment banker. The Michael Board concluded that the Reorganization will
allow Michael to acquire a large block of its stock at a discount from the
market price of such stock which Michael believes will be accretive to earnings
per share in 1996 and 1997. Although the Michael Board noted that the
Reorganization would result in a slight reduction, on a pro forma basis, in the
book value per share of Michael Common Stock, this reduction was not a
significant factor in the Michael Board's deliberations, as the reduction was
not significant and was not considered to be an important indicator of value in
the Reorganization. The effective redemption of Michael shares owned by NSU
should also remove the market's perceived adverse effect of NSU holding such a
large position in Michael and should increase the liquidity of Michael Common
Stock. The Michael Board concluded that the amount of indebtedness to be assumed
in the Reorganization would not have a material adverse affect on Michael
primarily because the range of NSU Net Indebtedness to be assumed in the
Reorganization can be serviced by New Michael without an adverse effect on its
earnings per share. Finally, the Michael Board authorized the Reorganization, in
part, based on NSU's willingness to complete the Distribution.
    
 
     The Michael Board believes that the terms of the Reorganization and the
transactions contemplated thereby are in the best interests of Michael and its
stockholders. Accordingly, the Michael Board has approved the Reorganization
Agreement and the Merger and recommends approval thereof by the stockholders of
Michael.
 
RECOMMENDATION OF NSU BOARD; NSU'S REASONS FOR THE REORGANIZATION
 
     THE NSU BOARD UNANIMOUSLY RECOMMENDS THAT HOLDERS OF NSU COMMON STOCK VOTE
FOR THE NSU PROPOSALS.
 
     NSU's Reasons for the Reorganization. On December 21, 1995, the NSU Board
met to consider the Reorganization, the terms of the Reorganization Agreement
and Distribution Agreement and the transactions contemplated thereby. NSU's
senior management and representatives of NSU's legal advisor and GAHS, its
independent financial advisor, made presentations to the NSU Board and discussed
with the NSU Board their views and analyses of various aspects of the proposed
transaction. The NSU Board reviewed and considered, among other things, the
background of the proposed transaction, NSU's strategic alternatives, financial
and valuation analyses of the transaction, the terms of the Reorganization
Agreement and the Distribution Agreement, the Merger, the Distribution, the New
Articles and the other matters described herein. GAHS provided an opinion that,
based upon the matters presented to the NSU Board and as set forth in its
opinion, as of such date, that the Reorganization was fair to the shareholders
of NSU from a financial point of view. See "-- Fairness Opinions."

evaluation of the Reorganization, the NSU Board did not quantify or otherwise
attempt to assign relative weights to the specific factors considered in
reaching its determination. In reaching its determination, the NSU Board
consulted with NSU management, as well as its legal counsel and financial
advisor, and considered a number of factors. The NSU Board considered that the
Reorganization will relieve NSU's operating businesses of significant debt
service obligations with respect to the Net Indebtedness of NSU to be assumed by
New Michael. The NSU Board also considered the advantages of avoiding income
taxation at the corporate level on NSU's holdings of Michael Common Stock while
providing its shareholders with a direct financial interest in Michael. Further,
the NSU Board considered that the Distribution would allow NSU's shareholders to
continue to hold an interest in NSU's other assets and that the Distribution was
required by Michael in order to avoid higher costs of capital to Michael.
 
     The NSU Board believes that the consummation of the Reorganization,
including the execution of the Reorganization Agreement, the Merger, the Reverse
Stock Split, the Distribution and the New Articles are in the best interests of
NSU and its shareholders. Based on these considerations, the NSU Board has
unanimously approved the Merger, the Reverse Stock Split, the Distribution and
the New Articles and authorized the execution of the Reorganization Agreement
and Distribution Agreement and recommended approval thereof by the shareholders
of NSU.
 
FAIRNESS OPINIONS
 
   
     Opinion of Michael's Financial Advisor. Michael retained Piper Jaffray as
its investment banker in connection with the Reorganization. Piper Jaffray is an
investment banking firm engaged, among other things, in the valuation of
businesses and their securities in connection with mergers and acquisitions,
underwriting and secondary distributions of securities, private placements and
valuations for estate, corporate and other purposes. While Michael interviewed
other financial advisors to evaluate the Reorganization, Piper Jaffray was
selected because of its long standing relationship with Michael as its financial
advisor and its familiarity with Michael and NSU, and because of its reputation
as a recognized national investment banking firm, with particular expertise in
the food and food products industry. Piper Jaffray was selected by Michael
because of its reputation as a recognized investment banking firm and its
familiarity with Michael and its respective component businesses. Piper Jaffray
makes a market in Michael's Common Stock, provides research coverage for
Michael, and acted as co-manager of public offerings of Michael Common Stock in
1987, 1988 and 1991 and as placement agent for an offering of senior notes in
1989.
    
 
     Piper Jaffray delivered written opinions to the Michael Board dated as of
December 21, 1995 and on or about the date of this Proxy Statement/Prospectus,
that, based upon and subject to the matters set forth in its written opinion as
of such dates, the effective price per share Michael is paying NSU, in the form
of the Net Indebtedness retained by New Michael, for the Retired Michael Shares
and the exchange of Michael Common Stock for New Michael Common Stock is fair,
from a financial point of view, to Michael. The full text of the written opinion
of Piper Jaffray, dated as of the date of this Proxy Statement/Prospectus, is
set forth as Appendix II to this Proxy Statement/Prospectus and describes the
assumptions made, matters considered and limits on the review undertaken. The
following summary of the opinion is qualified in its entirety by reference to
the full text of the opinion attached hereto as Appendix II. Michael
stockholders are urged to read the opinion in its entirety. The assumptions
made, matters considered and limits on the review undertaken in the opinion
dated the date of this Proxy Statement/Prospectus are substantially the same as
those contained in the opinion dated December 21, 1995.
 
     Piper Jaffray's opinion addresses only the fairness of the Reorganization
from a financial point of view to Michael and does not constitute a
recommendation to any stockholder of Michael as to how such stockholder should
vote with respect to the approval of the Reorganization. In connection with its
opinion, Piper Jaffray was not requested to opine as to, and their opinion does
not address, the merits of the basic business decision to proceed with or effect
the Reorganization. Piper Jaffray does not admit that it is an expert within the
meaning of the term "expert" as used in the Securities Act and the rules and
regulations promulgated thereunder, or that its opinions constitute a report or
valuation within the meaning of Section 11 of the Securities Act and the rules
and regulations promulgated thereunder.

     In connection with rendering its opinion, Piper Jaffray: (i) reviewed the
Reorganization Agreement; (ii) reviewed the annual reports, Forms 10-K and
audited financial statements for Michael for the three years ended December 31,
1994; (iii) reviewed the Forms 10-Q for Michael for the quarters ended March 31,
June 30 and September 30, 1995; (iv) reviewed the annual reports, Forms 10-K and
audited financial statements for NSU for the three years ended December 31,
1994; (v) reviewed the Forms 10-Q for NSU for the quarters ended March 31, June
30 and September 30, 1995; (vi) reviewed two year financial forecasts for
Michael furnished by Michael management; (vii) conducted discussions with
members of senior management of Michael; (viii) conducted discussions with
members of senior management of NSU; (ix) reviewed the historical prices and
trading activity for Michael Common Stock and NSU Common Stock; (x) reviewed the
financial terms, to the extent publicly available, of certain comparable
transactions it deemed relevant; (xi) considered the proforma effect of the
proposed Merger on Michael earnings per share for the two fiscal years ending
December 31, 1997; (xii) compared certain financial and securities data of
Michael with certain financial and securities data of companies deemed similar
to Michael or representative of the business sector in which Michael operates;
and (xiii) reviewed other financial data, performed other analyses and
considered other information as it deemed necessary and appropriate under the
circumstances.
 
   
     The financial forecasts provided to Piper Jaffray included a projected
statement of earnings for 1996 and suggested adjustments for 1997. In addition,
the forecasts provided projected weighted average shares outstanding to enable
Piper Jaffray to calculate projected earnings per share. The forecast was
adjusted to give effect to the Reorganization by including projected interest on
the NSU Net Indebtedness and incremental interest expense on current debt
adjusted for the effect of taxes. These adjustments resulted in a pro forma net
income amount for each of the years. Piper Jaffray then calculated the number of
shares retired as a result of the Reorganization, which was subtracted from the
projected weighted average shares outstanding and, in turn, used to calculate
pro forma earnings per share for each of the years. Earnings per share were
calculated as if the Reorganization had occurred as of January 1, 1996 and July
1, 1996 and for each of these scenarios a sensitivity analysis was completed on
the number of shares retired assuming a range of NSU Net Indebtedness of between
$25 million and $38 million and a price range for Michael Common Stock between
$11 and $17 per share. In each case, Piper Jaffray determined that the
Reorganization would be accretive to Michael's earning per share.
    
 
   
     In the course of its review, Piper Jaffray relied upon and assumed the
accuracy and completeness of the financial statements and other information
provided by Michael, NSU or otherwise made available to Piper Jaffray and did
not attempt independently to verify such information. Piper Jaffray further
relied upon the assurances of Michael's management that the information provided
pertaining to Michael was prepared on a reasonable basis and, with respect to
financial planning data, reflected the best currently available estimates. In
that regard, Piper Jaffray assumed, with Michael's consent, that any projections
or forecasts reflected the best currently available estimates and judgments of
the Michael management. Furthermore, Piper Jaffray assumed that neither Michael
nor NSU was a party to any pending transaction, including external financings,
recapitalizations, acquisitions or merger discussions, other than the Merger or
otherwise in the ordinary course of business. Piper Jaffray also assumed, with
Michael's consent, that the Merger, the Reverse Stock Split and the Distribution
will not result in the recognition of income or loss for federal income tax
purposes.
    
 
     In arriving at its opinion, Piper Jaffray did not perform any appraisals or
valuations of specific assets of Michael or NSU and expressed no opinion
regarding the liquidation value of Michael or NSU. Its opinion is necessarily
based upon information available to it, existing facts and circumstances and
economic, market and other conditions as they exist and are subject to
evaluation on the date of the opinion. Events occurring after the date of the
opinion could materially affect the assumptions used in preparing its opinion.
Piper Jaffray expressed no opinion as to the prices at which shares of Michael
Common Stock may trade at any future time.
 
     The following is a summary of the three primary analyses performed by Piper
Jaffray in connection with its opinion.
 
     Dilution Analysis. A dilution analysis was done to determine whether the
transaction is dilutive to Michael's earnings per share. The Reorganization
Agreement contemplates that Michael will assume between $25 million and $38
million in Net Indebtedness from NSU in exchange for the retirement of a portion
of the
 
                                       36
<PAGE>   45
 
   
Michael Common Stock held by NSU. The income statement effects from the
transaction are an increased level of interest expense due to the assumption of
debt and a decreased number of shares of Michael Common Stock outstanding due to
the retirement of a portion of the Michael Common Stock held by NSU. Michael's
pre-transaction earnings per share were compared to the post-transaction
earnings per share to see if and when the Reorganization was dilutive to
Michael's earnings. Piper Jaffray's analysis of those figures currently supports
the conclusion that the transaction will be accretive to New Michael earnings
per share in both fiscal 1996 and 1997. The analysis described above resulted in
a range of accretion to earnings per share for the years 1996 and 1997 from a
low of 1.3% to a high of 16.9%.
    
 
     Comparable Transactions. Piper Jaffray prepared a comparable transaction
analysis to compare the discount to market to be received by Michael for the
retirement of Michael Common Stock in the Reorganization. The comparable
transaction analysis involves a review of transactions deemed comparable to the
Reorganization. Piper Jaffray focused on the following criteria to obtain a
group of such comparables: (i) privately negotiated transactions in which a
public company acquired a minority block of stock from a shareholder, excluding
open market transactions; (ii) the market capitalization of the acquiring
company exceeded $100 million; (iii) the percentage of shares repurchased was
greater than or equal to 10% but less than 50%; and (iv) the transactions
occurred between January 1, 1992, and December 21, 1995. These criteria yielded
37 transactions.
 
     Piper Jaffray then reviewed the premium or discount paid for the block of
stock at three different points: one day prior to the announcement date, one
week prior to the announcement date and four weeks prior to the announcement
date. Piper Jaffray concluded that the discount factor for the Michael Common
Stock to be retired in consideration for the retention of the Net Indebtedness
compared favorably to the mean and median discounts for the transactions it
reviewed.
 
     Cost Analysis. Piper Jaffray prepared a cost analysis that involved a
review of the costs of the Reorganization to Michael in order to determine a
range of discounts deemed appropriate for the transaction to cover such costs.
The costs Piper Jaffray analyzed included: (i) fixed costs, including all
professional fees (accountants, lawyers and financial advisors) and the costs
associated with the Michael stockholder approval process; and (ii) variable
costs, including (a) interest expense on NSU Indebtedness retained by New
Michael, after taxes; (b) incremental interest expense expected to be incurred
on Michael's current line of credit; and (c) underwriting expense for
potentially reselling the repurchased stock in a public equity underwriting. The
aggregate of these costs is dependent on the amount of debt assumed by Michael
and the Michael Common Stock average per share price assumed in the redemption
of Michael Retired Shares and is currently estimated to be in the range of $2.5
million to $3.8 million.
 
     The appropriate discount to apply to the Michael Common Stock price in
order to determine the amount of shares to be repurchased in consideration for
assuming the Net Indebtedness was calculated by dividing the gross amount of the
costs (fixed plus variable) by the sum of the gross amount of the costs plus the
amount of Net Indebtedness. Based on Piper Jaffray's current analysis, the range
of implied appropriate discounts compared favorably to the discount factor
range.
 
   
     Piper Jaffray focused on the foregoing analysis because, in its opinion,
the most relevant factors in determining the fairness to Michael for the
Reorganization was whether earnings per share would increase as a result of the
Reorganization and whether the discount received for the retirement of shares of
Michael Common Stock held by NSU was adequate in the context of other similar
transactions and actual costs incurred as a result of the Reorganization. Piper
Jaffray did not rely on other methodologies often used in determining the
fairness of reorganization transactions, such as the discounted cash flow
analysis, because in the context of a share repurchase transaction such analyses
were deemed not to be relevant.
    
 
   
     In addition to these primary analyses, Piper Jaffray also reviewed certain
stock market information on Michael and NSU as well as on comparable companies
to Michael. The comparable companies included public companies with SIC codes in
the range of 2011 through 2099 (food and kindred products) which had similar
product or market characteristics. Based on this criteria and other factors
considered by Piper Jaffray, eight companies were chosen as comparable companies
to Michael: ConAgra, Inc.; Dean Foods Co.; Foodbrands America, Inc.; Hormel
Foods Corp.; International Multifoods Corp.; Morningstar Group, Inc.;
    
 
                                       37
<PAGE>   46
 
   
Northland Cranberries, Inc.; and Tyson Foods, Inc. While Piper Jaffray
considered these reviews to be relevant and prudent, they did not play a major
role in their determination of the fairness of the consideration exchanged.
    
 
     The foregoing is a summary of the financial analyses used by Piper Jaffray
in connection with rendering its opinion. The preparation of a fairness opinion
is a complex process and is not necessarily susceptible to partial analysis or
summary description. Selecting portions of the analyses or the summary set forth
above, without considering the analyses as a whole, could create an incomplete
view of the processes underlying Piper Jaffray's opinion. In arriving at its
opinion, Piper Jaffray considered the results of all such analyses. The analyses
were prepared solely for the purposes of Piper Jaffray providing its opinion as
to the fairness of the repurchase and share exchange, from a financial point of
view, to Michael and do not purport to be appraisals or necessarily reflect the
prices at which businesses or securities actually may be sold. No company used
in the comparable company analysis summarized above is identical to Michael and
no transaction used in the comparable transaction analysis summarized above is
identical to the transactions described herein. Any analysis of the fairness of
the Merger, from a financial point of view, to Michael involves complex
considerations and judgments concerning differences in the potential financial
and operating characteristics of the comparable companies and transactions and
other factors in relation to the trading and acquisition values of the
comparable companies. Analyses based upon forecasts of future results are not
necessarily indicative of actual future results, which may be significantly more
or less favorable than those suggested by such analyses. As described above,
Piper Jaffray's opinion was one of many factors taken into consideration by the
Michael Board in making its determination to approve the Reorganization
Agreement.
 
     Michael has agreed to pay Piper Jaffray a fee of $220,000 for rendering its
financial advisory services, including its opinion. This fee was not conditioned
upon the ability of Piper Jaffray to render its opinion. Michael also agreed to
reimburse Piper Jaffray for its reasonable out-of-pocket expenses, including the
fees and disbursements of its counsel, and to indemnify Piper Jaffray against
certain liabilities, including liabilities under the federal securities laws.
 
   
     Opinion of NSU's Financial Advisor. NSU retained GAHS as its financial
advisor in connection with the Reorganization. Prior to retaining GAHS, NSU
interviewed two other investment banking firms. In selecting GAHS as its
financial advisor, NSU considered, among other factors, (i) the reputation of
GAHS, particularly relative to advising companies in complex transactions
involving complicated tax and corporate law issues, (ii) the experience level of
the individuals that would be directly involved in advising NSU, (iii) the fact
that GAHS had not previously had any relationship with NSU and might offer a
new, independent perspective concerning the transaction proposal that was then
being discussed by NSU and Michael, as well as alternative transactions and
transaction structures, and (iv) the proposed fees and fee structure of the
engagement. As a customary part of its investment banking business, GAHS is
engaged in the valuation of businesses and securities in connection with mergers
and acquisitions, private placements, and valuations for estate, corporate, and
other purposes. GAHS does not make a market in the NSU Common Stock or Michael
Common Stock.
    
 
     GAHS delivered its written opinion to the NSU Board, dated as of December
21, 1995, and as of the date of this Proxy Statement/Prospectus that, based upon
and subject to the matters set forth in its written opinions, as of each such
date, the Reorganization is fair to NSU's shareholders from a financial point of
view. The full text of the written opinion of GAHS, dated as of the date of this
Proxy Statement/Prospectus, is set forth as Appendix III to this Proxy
Statement/Prospectus and describes the assumptions made, matters considered, and
limits on the review undertaken. NSU shareholders are urged to read the opinion
in its entirety. The following summary of the opinion is qualified in its
entirety by reference to the full text of the opinion attached as Appendix III
to this Proxy Statement/Prospectus. GAHS does not admit that it is an expert
within the meaning of the term "expert" as used in the Securities Act and the
rules and regulations promulgated thereunder, or that its opinions constitute a
report or valuation within the meaning of Section 11 of the Securities Act and
the rules and regulations promulgated thereunder.
 
     GAHS's opinion addresses only the fairness of the Reorganization, from a
financial point of view, to NSU's shareholders, and does not constitute a
recommendation to any NSU shareholder as to how such
 
                                       38
<PAGE>   47
 
shareholder should vote with respect to any of the NSU Proposals. In connection
with its opinion, GAHS was not requested to opine as to, and its opinion does
not address the merits of the basic business decision to proceed with or effect
the Reorganization.
 
     In arriving at its opinion, GAHS undertook such reviews, analyses, and
inquiries as it deemed necessary and appropriate under the circumstances. Among
other things, GAHS reviewed the Reorganization Agreement, the Distribution
Agreement, and financial and other information relating to NSU and Michael. GAHS
reviewed the reported price and trading activity of NSU and Michael Common
Stock. GAHS compared certain financial and stock market information with respect
to NSU and Michael with similar information for certain other companies,
securities of which are publicly traded. GAHS made inquiries of NSU's management
as to NSU's financial condition, operating results, business outlook plans and
opportunities. GAHS also conducted discussions with members of senior management
of Michael, and reviewed all publicly available information relative to NSU and
Michael.
 
     GAHS relied upon and assumed the accuracy, completeness, and fairness of
the financial statements and other information of NSU and Michael, and did not
attempt independently to verify such information. GAHS further relied upon
assurances by NSU that the information provided to GAHS had a reasonable basis,
and with respect to projections and other business outlook information,
reflected the best currently available estimates, and that NSU was not aware of
any information or fact that would make such information provided to GAHS
incomplete or misleading.
 
     GAHS's opinion is not based on any specific appraisal of the liquidation
value of NSU or Michael or any of their respective assets, or of ENStar or any
of its assets. GAHS did not actively solicit indications of interest or value
from any third parties for NSU or any of its assets; nor did GAHS solicit
indications of interest or value from any third parties for Michael. GAHS is not
expressing any opinion as to the price at which shares of Common Stock of ENStar
or New Michael will trade subsequent to the Effective Date, and GAHS expressly
disclaims any opinion as to prices at which shares of NSU or Michael Common
Stock have traded prior to the date of the Reorganization. GAHS's opinion is
based on the information made available to it and the facts and circumstances as
they exist as of the date of such opinion, and is subject to evaluation on the
date thereof. Events occurring after the date of such opinion could materially
affect the assumptions used in preparing such opinion. GAHS was not requested to
opine, and is not opining, in any way concerning other transactions or
agreements entered into in conjunction with the Reorganization.
 
     GAHS assumed that neither NSU nor Michael was a party to any pending
transaction, including external financings, recapitalizations, acquisitions, or
merger discussions, other than the Reorganization, or in the ordinary course of
business. GAHS also assumed, based on NSU's instructions, that the
Reorganization including the Merger and the Distribution, will not result in
recognition of income or loss for federal income tax purposes.
 
   
     The following is a summary of the primary analysis performed by GAHS in
connection with its opinion. As the principal element of the Reorganization with
economic consequences to NSU and its shareholders is the terms of the effective
sale by NSU of a portion of its holdings of Michael Common Stock in exchange for
the assumption by Michael of the NSU Net Indebtedness in connection with the
Merger, GAHS focused on the two types of analysis summarized below which it
deemed most relevant: (i) an economic comparison of NSU's alternatives for its
Michael Common Stock, and (ii) a review of comparable transactions. GAHS did not
rely on other methodologies often used in determining the fairness of
reorganization transactions, such as discounted cash flow analysis, because in
the context of a transaction that is effectively a sale by NSU of its Michael
Common Stock, such analyses were deemed not to be relevant.
    
 
   
     Economic Comparison of NSU's Alternatives for its Michael Common
Stock. Because ENStar will be configured so as to represent primarily the same
assets and liabilities currently held by NSU, with the exception of the Michael
Common Stock and the Net Indebtedness of NSU, ENStar will have the same
intrinsic value as NSU prior to the Reorganization, modified by the economic
impact of these two exceptions. Therefore, as noted above, the net economic
impact of the Reorganization on NSU shareholders is measured by the financial
terms of the exchange by NSU of the Retired Michael Shares for Michael's
assumption of NSU's Net Indebtedness. GAHS's first analysis focused on a
comparison of the economic impact of this
    
 
                                       39
<PAGE>   48
 
defacto sale by NSU to Michael of the Retired Michael Shares, to other
alternatives open to NSU for disposition of the Michael Shares held by NSU.
 
          - Public Sale by NSU. GAHS analyzed and evaluated the alternatives
     available to NSU for registration of its Michael Common Stock under
     applicable federal and state securities laws, and selling such shares to
     the public through a secondary offering or in an unregistered, piecemeal
     fashion as permitted under applicable laws. GAHS concluded that such
     alternative would result in lesser after-tax proceeds and inferior
     intrinsic value to NSU's shareholders as compared to the Reorganization,
     due to the costs and expenses of such an option, including without
     limitation, the income taxes payable by NSU in conjunction with such a sale
     or sales, as well as other market issues relating to the impact of such
     transaction on the trading value of the Michael Common Stock.
 
          - Private Sale by NSU of its Michael Shares. After analysis and
     evaluation, GAHS concluded that a private sale by NSU of its Michael
     shares, without registration under applicable federal and state securities
     laws, was not practical or appropriate. Moreover, GAHS concluded that, in
     light of the tax impact of such an alternative, the intrinsic value to
     NSU's shareholders of such a private sale would be inferior to the
     Reorganization.
 
   
          - The Sale of Michael in its Entirety. After analysis and evaluation
     and discussions with the management of Michael, including Gregg Ostrander,
     its President and Chief Executive Officer and John Reedy, its Chief
     Financial Officer, and the management of NSU and the NSU Board, GAHS
     concluded that the possible sale of Michael in its entirety was unlikely
     and impractical. Such a sale, however, might result in a control premium
     and, if properly structured as a tax-free reorganization with respect to
     NSU, could result in greater value to the NSU shareholders than that which
     they may receive in the Reorganization. Management of Michael confirmed to
     GAHS, however, that it had no present intention to pursue such a
     transaction based on its belief that it would not be in the best interests
     of Michael's shareholders. Moreover, after due consideration and
     discussions with management of NSU, GAHS concluded that NSU, despite its
     significant holdings of Michael Common Stock, was not in a position to
     unilaterally take action that would bring about a sale of Michael in its
     entirety without the support or initiation of Michael's management. GAHS
     reached this conclusion for several reasons. First, as noted above, a
     successful sale of Michael in its entirety would be difficult without
     cooperation from management, for example, in gaining access to information
     about Michael that any third party acquiror would expect to have in
     entering into such a transaction. Second, a sale without support of Michael
     management could present potentially high transaction costs in the event
     that NSU sought to unseat the current Michael Board and replace management
     through a proxy contest. In addition to potentially high costs, the effect
     a proxy contest might have on the management of Michael, for example, the
     loss of key executives, could reduce the ultimate value of such an approach
     to selling Michael. Third, although there have been a number of potential
     buyers interested in purchasing discrete product lines of Michael, there
     likely would be few potential buyers for Michael as a whole, given the
     diversity of its product lines. As a result, marketing Michael as a whole
     would be difficult with no guarantee of success, and the failure of such an
     effort would likely adversely affect Michael's business. Finally, a
     relevant consideration in GAHS's analysis was the requirement that any such
     sale of Michael in its entirety would be required to be structured as a
     tax-free reorganization with respect to NSU also, in order to avoid
     recognition of substantial taxable income by NSU so as to achieve an
     intrinsic value to NSU shareholders equal to or greater than the
     Reorganization.
    
 
     Comparable Transactions. GAHS prepared a comparable transaction analysis to
compare the discount to market used in determining the number of Retired Michael
Shares in the Reorganization. The comparable transaction analysis involved a
review of transactions deemed comparable to the Merger. GAHS focused on the
following criteria to determine a group of comparables: (i) privately negotiated
transactions in which a public company acquired a minority block of stock from a
shareholder, excluding open market transactions; (ii) the market capitalizations
of the acquiring company exceeded $100 million; (iii) the percentage of shares
repurchased was greater than 10% but less than 50%; and (iv) the transactions
occurred between January 1, 1992 and December 21, 1995.
 
                                       40
<PAGE>   49
 
     In addition, GAHS considered and evaluated the unique objectives and
requirements confronting buyer and seller in such comparable transactions,
including without limitation, the alternative opportunities for the seller to
dispose of the stock and the relevance of tax-free or tax-advantaged transaction
structures.
 
     GAHS then reviewed the premium or discount paid for the block of stock at
various points in time prior to and at the effective date of such transactions.
While actual discounts ranged from nominal to 40% or greater, the most
comparable transactions involved discounts in the 5% to 15% range. Key factors
in determining the appropriate discount level in such transactions include the
strength of the public market for the shares, the seller's alternatives for
divesting such shares, the redeeming company's cost of capital and financial
capability, its expenses incurred in conjunction with the stock repurchase, the
impact of the stock repurchase on the company's balance sheet and future cost of
borrowing, as well as requirements for prospective secondary offerings by the
redeeming company, and other special circumstances, including without
limitation, tax advantages and/or costs to the selling shareholder and/or the
redeeming company. Of particular relevance in GAHS's opinion, was the redemption
by E.I. DuPont de Nemours and Company of a substantial number of its shares held
by The Seagram Company Ltd. in April, 1995. The transaction highlights the
market precedence for focusing on the after-tax attributes of a redemption to
the selling company's shareholders.
 
     ENStar Strategic Considerations. GAHS considered that strategic
considerations with respect to the prospects of ENStar were not meaningfully
relevant to the issue of fairness of the Reorganization, due in large measure to
the fact that ENStar represents the same assets and liabilities as NSU prior to
the effective date of the Reorganization, with the exception of the elimination
of the Retired Michael Shares and the Net Indebtedness. Nevertheless, GAHS
considered that, in general, the Reorganization would have a favorable impact on
ENStar's strategic prospects for numerous reasons, including ENStar's increased
focus and decreased leverage vis-a-vis NSU.
 
   
     The foregoing is a summary of the analyses used by GAHS in connection with
rendering its opinion. The preparation of a fairness opinion is a complex
process and is not necessarily susceptible to partial analysis or summary
description. Selecting portions of the analyses or of the summary set forth
above, without considering the analyses as a whole, could create an incomplete
view of the processes underlying GAHS's opinion. In arriving at its opinion,
GAHS considered the results of all such analyses. The analyses were prepared
solely for the purposes of GAHS providing its opinion as to the fairness of the
Reorganization to NSU shareholders, from a financial point of view, and do not
purport to be appraisals or necessarily reflect the prices at which businesses
or securities actually may be sold. No transaction used in the comparable
transaction analysis summarized above is identical to the Reorganization. Any
analysis of the fairness of the Reorganization to NSU shareholders, from a
financial point of view, involves complex considerations and judgments
concerning differences in the potential financial and operating characteristics
of the comparable transactions and the companies involved and other factors in
relation to the trading and acquisition values of the companies involved in such
transactions. Analyses based upon forecasts of future results are not
necessarily indicative of actual future results, which may be significantly more
or less favorable than those suggested by such analyses. As described above,
GAHS's opinion was one of many factors taken into consideration by the NSU Board
in making its determination to approve the Reorganization.
    
 
     GAHS has been paid $77,500 for its financial advisory services to date,
including $25,000 in connection with the delivery of its fairness opinion on
December 21, 1995. If the Reorganization is consummated, GAHS will receive an
additional $175,000 to $225,000, depending upon the amount of the Discount
Factor, for its financial advisory services and $75,000 for the issuance of its
fairness opinion. Reasonable out-of-pocket expenses of GAHS will also be
reimbursed by NSU, and NSU has agreed to indemnify GAHS against certain
liabilities.
 
PROCEDURE FOR EXCHANGE OF CERTIFICATES
 
     General. As soon as practicable after the Effective Time, The First
National Bank of Boston, or another person mutually designated by Michael and
NSU, in its capacity as the Exchange Agent, will send a transmittal letter to
each Michael stockholder and NSU shareholder. The transmittal letter will
contain
 
                                       41
<PAGE>   50
 
instructions with respect to the surrender of certificates representing Michael
Common Stock and NSU Common Stock in exchange for certificates evidencing New
Michael Common Stock.
 
     Michael. Upon receipt of stock certificates representing shares of Michael
Common Stock ("Michael Certificates"), the Exchange Agent will deliver shares of
New Michael Common Stock to the surrendering stockholder in accordance with the
terms of the Reorganization Agreement.
 
     If any issuance of shares of New Michael Common Stock in exchange for
shares of Michael Common Stock is to be made to a person other than the Michael
stockholder in whose name the Michael Certificate is registered at the Effective
Time, it will be a condition of such exchange that the certificate so
surrendered be properly endorsed or otherwise in proper form for transfer and
that the Michael stockholder requesting such issuance either pay any transfer or
other tax required or establish to the satisfaction of New Michael that such tax
has been paid or is not payable.
 
     After the Effective Time, there will be no further transfers of Michael
Common Stock on the stock transfer books of Michael. If a Michael Certificate
representing Michael Common Stock is presented for transfer, it will be canceled
and a certificate representing the same number of shares of New Michael Common
Stock will be issued in exchange therefor.
 
     After the Effective Time and until surrendered, shares of Michael Common
Stock will be deemed for all corporate purposes to evidence ownership of an
equal number of shares of New Michael Common Stock. New Michael will not be
obligated to deliver certificates evidencing shares of New Michael Common Stock
to former shareholders of Michael until the Michael Certificates relating to
such shares are surrendered. All declared dividends and distributions which
shall have become payable with respect to such New Michael Common Stock in
respect of a record date after the Effective Time will be paid to the holder of
record of the full shares of New Michael Common Stock regardless of whether such
holder has surrendered for exchange his or her certificates evidencing Michael
Common Stock.
 
     NSU. Upon receipt of stock certificates evidencing shares of NSU Common
Stock ("NSU Certificates"), the Exchange Agent will deliver such number of full
shares of New Michael Common Stock and cash in lieu of fractional shares of New
Michael Common Stock, if any, as such shareholder is entitled to receive after
the Reverse Stock Split, together with any dividends or other distributions of
New Michael to which such shareholder is entitled. No fractional shares of New
Michael Common Stock will be issued to NSU shareholders in connection with the
Reverse Stock Split. In lieu of issuing fractional shares, NSU shareholders will
receive cash (without interest) determined by multiplying (a) the Average Price
of Michael Common Stock times (b) the fractional share interest which such
shareholders would otherwise be entitled to receive.
 
     If any issuance of shares of New Michael Common Stock in exchange for
shares of NSU Common Stock is to be made to a person other than the NSU
shareholder in whose name the certificate is registered at the Effective Time,
it will be a condition of such exchange that the certificate so surrendered be
properly endorsed or otherwise in proper form for transfer and that the NSU
shareholder requesting such issuance either pay any transfer or other tax
required or establish to the satisfaction of New Michael that such tax has been
paid or is not payable.
 
     After the Effective Time, there will be no further transfers of pre-Reverse
Stock Split NSU Common Stock on the stock transfer books of New Michael. If a
certificate representing pre-Reverse Stock Split NSU Common Stock is presented
for transfer, it will be canceled and a certificate representing the appropriate
number of full shares of New Michael Common Stock and cash in lieu of fractional
shares and any dividends and distributions will be issued in exchange therefor.
 
     After the Effective Time and until surrendered, shares of pre-Reverse Stock
Split NSU Common Stock will be deemed for all corporate purposes, other than the
payment of dividends and distributions, to evidence ownership of the number of
full shares of New Michael Common Stock into which such NSU Common Stock was
combined in the Reverse Stock Split. No dividends or other distributions, if
any, payable to holders of NSU Common Stock will be paid to the holders of any
NSU Certificates until such certificates are surrendered. Upon surrender of such
NSU Certificates, all such declared dividends and distributions which
 
                                       42
<PAGE>   51
 
shall have become payable with respect to such NSU Common Stock in respect of a
record date after the Effective Time will be paid to the holder of record of the
full shares of New Michael Common Stock represented by the certificate issued in
exchange therefor, without interest.
 
DISTRIBUTION OF ENSTAR COMMON STOCK
 
     On or prior to the Effective Date of the Merger, NSU will deliver to its
transfer agent certificates representing all of the outstanding shares of ENStar
Common Stock. On the Effective Date, immediately after the Effective Time, NSU
will deliver to such transfer agent an instruction to distribute as promptly as
practicable following the Effective Date to each holder of record of NSU Common
Stock on the record date for the Distribution stock certificates evidencing one
share of ENStar Common Stock for every three shares of NSU Common Stock held of
record by such shareholder on such record date for the Distribution and cash in
lieu of any fractional shares of ENStar Common Stock. No certificate or scrip
representing fractional shares of ENStar Common Stock will be issued as part of
the Distribution, and in lieu of receiving fractional shares each holder of NSU
Common Stock who would otherwise be entitled to receive a fractional share of
ENStar Common Stock pursuant to the Distribution will receive cash for such
fractional share. NSU will instruct its transfer agent to determine the number
of whole shares and fractional shares of ENStar Common Stock allocable to each
holder of record of NSU Common Stock as of the record date for Distribution, to
aggregate all such fractional shares into whole shares and sell the whole shares
obtained thereby in the open market, if possible, at then prevailing prices on
behalf of the holders who otherwise would be entitled to receive fractional
share interests and to distribute to each such holder such holder's ratable
share of the total proceeds of such sale. ENStar will bear the costs and
commissions incurred in connection with such sale. If the transfer agent is
unable to sell such shares in the open market, ENStar will pay to such holders,
in lieu of any fractional share, an amount of cash determined by multiplying (a)
the average closing price per share of ENStar Common Stock on the Nasdaq
National Market during the five days following the Effective Date times (b) the
fractional share interest to which such holder would otherwise be entitled.
 
LOST, STOLEN OR DESTROYED CERTIFICATES
 
     In the event any Michael Certificates or NSU Certificates have been lost,
stolen or destroyed, the Exchange Agent will issue shares of New Michael Common
Stock, in exchange for such lost, stolen or destroyed certificates upon the
making of an affidavit of that fact by the owner of such certificates, provided
that New Michael may, in its discretion require the holder of such lost, stolen
or destroyed certificates to deliver a bond in a reasonable sum as indemnity
against any claim that may be made against New Michael or the Exchange Agent
with respect to the certificates alleged to have been lost, stolen or destroyed.
 
DETAILED INSTRUCTIONS, INCLUDING A TRANSMITTAL LETTER, WILL BE MAILED TO MICHAEL
STOCKHOLDERS AND NSU SHAREHOLDERS PROMPTLY FOLLOWING THE EFFECTIVE TIME AS TO
THE METHOD OF EXCHANGING CERTIFICATES FORMERLY REPRESENTING SHARES OF MICHAEL
AND NSU COMMON STOCK. MICHAEL STOCKHOLDERS AND NSU SHAREHOLDERS SHOULD NOT SEND
CERTIFICATES REPRESENTING THEIR SHARES TO THE EXCHANGE AGENT PRIOR TO RECEIPT OF
THE TRANSMITTAL LETTER.
 
ESCHEAT AND WITHHOLDING
 
     NSU, Merger Co., New Michael and ENStar will not be liable to any holder of
NSU Common Stock or Michael Common Stock for any consideration due such holder
as a part of the Reorganization delivered to a public official pursuant to any
applicable abandoned property, escheat or similar law. New Michael or the
Exchange Agent will be entitled to deduct and withhold from such consideration
to any NSU shareholder such amounts as New Michael or the Exchange Agent is
required to deduct and withhold with respect to the making of such payment under
any provision of federal, state, local or foreign tax law.

INTEREST OF CERTAIN PERSONS IN THE REORGANIZATION
 
   
     In considering the respective recommendations of the Michael Board and the
NSU Board regarding the Reorganization Agreement and the transactions
contemplated thereby, stockholders of Michael and shareholders of NSU should be
aware that certain members of the management of Michael and NSU and the Michael
and the NSU Boards have certain interests in the Reorganization that may be
different from, or in addition to, the interests of stockholders of Michael and
shareholders of NSU generally. In approving the Reorganization Agreement and the
transactions contemplated thereby, all members of the respective NSU and Michael
Boards, including the outside directors thereof, were aware of the various
interests of certain Michael and NSU management and Michael and NSU Board
members had in the transactions contemplated by the Reorganization. Also, each
of NSU and Michael engaged their respective financial advisors and obtained a
fairness opinion as to the fairness of the Reorganization from such advisors at
the time of approving the Reorganization Agreement. The Michael Board, in
addition to taking the precautions noted above, obtained the recusal of three of
its members, Messrs. Michael, Michael and Efron who are shareholders and
officers or directors of NSU, from its meeting approving the Reorganization
Agreement.
    
 
   
     Additionally, the NSU Board considered that the Michael Family holds
approximately 60% of the outstanding NSU Common Stock; however, it was the NSU
Board's view that the interests of the Michael Family were aligned with the
interests of the other shareholders of NSU. In this regard, the NSU Board noted
that all NSU shareholders will receive equal treatment in the Reorganization.
Also, the terms of the Orderly Disposition Agreement, which was required by
Michael as a condition to executing the Reorganization Agreement, were fully
disclosed to all of the members of the NSU Board.
    
 
     Michael. All of the current directors of Michael, except James H. Michael
and Orville L. Freeman, will become directors of New Michael. In addition, the
executive officers of Michael will become executive officers of New Michael. See
"THE REORGANIZATION AGREEMENT -- New Michael Management Following the
Reorganization."
 
   
     Pursuant to the Reorganization Agreement, New Michael will assume all
existing Michael stock option plans and the stock award portion of Michael's
Executive Incentive Plan. At the Effective Time, each outstanding right to
purchase shares of Michael Common Stock (a "Michael Option"), will be assumed by
New Michael in such manner that it is converted into an option to purchase the
same number of shares of New Michael Common Stock at the same exercise price.
Each Michael Option assumed by New Michael will have the same terms and
conditions as then are applicable to such Michael Option. As of             ,
1996, directors and executive officers of Michael held outstanding Michael
Options to purchase             shares of Michael Common Stock at exercise
prices ranging from             .
    
 
     NSU. At or prior to the Effective Time, all of the NSU stock options
outstanding under the NSU stock option plans will be canceled or exercised and
all NSU stock option plans will terminate.
 
     Concurrently with the execution of the Reorganization Agreement, the
Michael Family Shareholders, who own an aggregate of 5,685,100 shares (or
approximately 60%) of the outstanding Common Stock of NSU, entered into the
Orderly Disposition Agreement. Under the Orderly Disposition Agreement, the
Michael Family Shareholders have agreed until the Effective Time (i) not to
sell, offer to sell, hypothecate or transfer any shares of NSU, unless sold
pursuant to Rule 144 of the Securities and Exchange Commission, pledged to
secure certain surety bonds or transferred among the Michael Family
Shareholders, (ii) to cause NSU to vote in favor of the Merger, the Reverse
Stock Split, the Distribution and the election of directors nominated by the New
Michael Board of Directors at any meeting of New Michael shareholders called for
such purpose, and (iii) prepare any necessary pre-merger notifications as
required under the HSR Act. The Michael Family Shareholders have also agreed to
refrain for a period of two years following the Effective Date from selling,
pledging or otherwise disposing of (i) shares of New Michael Common Stock
exceeding 5% of the outstanding shares of New Michael Common Stock, or (ii) any
of their shares to a purchaser who owns or would own more than 5% of the
outstanding New Michael Common Stock without giving an option to New Michael to
purchase such shares, except that they may pledge shares to secure certain
surety bonds. New Michael must exercise its option by completing the purchase of
the shares within twenty days of notification by the Michael Family Shareholders
of an intent to sell. The restrictions do not apply if a tender offer is made
 
                                       44
<PAGE>   53
 
   
for all of the outstanding New Michael Common Stock unless management of New
Michael announces opposition to the tender offer. In addition, the Michael
Family Shareholders are entitled during such two year period to certain
piggyback registration rights under the Act with respect to the New Michael
Common Stock if New Michael proposes to register common stock under the Act. The
Michael Family Shareholders also are entitled up to two times, during such two
year period, to request registration of a minimum of 500,000 shares for sale in
a public offering. However, New Michael would not be obligated to register
shares if registration would require a special audit and New Michael may delay
the registration for 120 days under certain circumstances. Each selling Michael
Family Shareholder will pay New Michael a pro rata share of the registration
expenses, the aggregate fees and disbursements of underwriters, underwriting
discounts and commissions and transfer taxes, if any, and fees and disbursements
of counsel to the Michael Family Shareholders in connection with any
registration.
    
 
     Finally, for a period of two years following the Effective Time, the
Michael Family Shareholders will be entitled to nominate two directors to the
New Michael Board if they collectively own ten percent or more of the
outstanding common stock of New Michael and one director to the Board if their
ownership is below ten percent. The initial designees of the Michael Family
Shareholders to the New Michael Board are Jeffrey J. Michael and Miles E. Efron,
both of whom currently are Michael directors. A copy of the Orderly Disposition
Agreement is attached hereto as Exhibit E to the Reorganization Agreement
included in Appendix I.
 
   
     Peter E. Flynn, Executive Vice President, Chief Financial Officer and
Secretary of NSU, is a party to an employment agreement with NSU and Transition
which terminates December 31, 1997. Pursuant to that agreement, if Mr. Flynn's
employment is terminated due to a "change in control" of NSU, Mr. Flynn is
entitled to receive a single lump sum payment of $297,000. Mr. Flynn holds
options to purchase an aggregate of 134,500 shares of NSU Common Stock with
exercise prices ranging from $4.00 per share to $10.125 per share. The latest
grant of such options was made on August 3, 1992 for 30,000 shares at an
exercise price of $4.63 per share. As of June   , 1996, the value of such
options was $          , assuming a closing price of $          per share of NSU
Common Stock on such date. If Mr. Flynn is terminated by NSU, all of such
outstanding options immediately become vested. The consummation of the
Reorganization will result in such a change in control under the terms of that
agreement and Mr. Flynn's employment with NSU will be terminated.
    
 
ACCOUNTING TREATMENT
 
     The Merger will be accounted for as a business combination utilizing the
reverse acquisition method with Michael being the acquiror for accounting
purposes under generally accepted accounting principles. As such, the Merger
will be treated as an acquisition using the purchase method of accounting with
no change in the recorded amount of Michael's assets and liabilities. The assets
and liabilities of NSU that are acquired as a result of the Merger will be
recorded at their fair market values. The ENStar assets and liabilities will be
recorded at their historic amounts, as recorded in the books and records of NSU,
following the Distribution.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     Consummation of the Reorganization is conditional upon receiving the
following rulings from the IRS:
 
          The Merger. The Merger will qualify as a reorganization within the
     meaning of Section 368(a)(1)(B) of the Code and NSU and Michael will each
     be a party to the reorganization within the meaning of Section 368(b) of
     the Code. Accordingly: (i) no income, gain or loss will be recognized by
     NSU or Michael as a result of the consummation of the Merger; (ii) no gain
     or loss will be recognized by the holders of Michael Common Stock upon the
     exchange of Michael Common Stock solely for New Michael Common Stock
     pursuant to the Merger; (iii) the basis of the New Michael Common Stock
     received by a stockholder of Michael pursuant to the Merger will be the
     same as the basis of the Michael Common Stock surrendered in exchange
     therefor; and (iv) the holding period of the New Michael Common Stock
     received by a stockholder of Michael pursuant to the Merger will include
     the period during which the Michael Common Stock surrendered therefor was
     held, provided the Michael Common Stock is a capital asset in the hands of
     the stockholder of Michael at the time of the Merger.
 
                                       45
<PAGE>   54
 
          The Reverse Stock Split. The Reverse Stock Split will not be treated
     as a stock distribution, or a transaction that has the effect of such a
     distribution, to which Sections 301, 305(b) or 305(c) of the Code apply.
     Accordingly, no taxable income will be recognized under such Sections by
     any of the shareholders of NSU except for cash paid in lieu of fractional
     shares, which cash payment shall be treated as received by the holder of
     NSU Common Stock as a distribution in redemption of the fractional share
     interest and such shareholder will recognize gain or loss, subject to the
     provisions and limitations of Section 302 of the Code.
 
          The Distribution. The Distribution will qualify as a tax-free
     distribution under Sections 355 and 368(a)(1)(D) of the Code. Accordingly:
     (i) NSU shareholders will not recognize income, gain or loss upon the
     receipt of ENStar Common Stock; (ii) the tax basis of the shares of ENStar
     Common Stock and New Michael Common Stock (including any fractional share
     interests to which an NSU shareholder is entitled) held by an NSU
     shareholder after the Distribution will be the same as the tax basis of the
     shares of NSU Common Stock held by such shareholder immediately before the
     Distribution, allocated in proportion to the fair market values of the
     shares of ENStar Common Stock and New Michael Common Stock on the
     Distribution Date; (iii) the holding period for the shares of ENStar Common
     Stock received by the NSU shareholders will include the holding period of
     the shares of NSU Common Stock with respect to which the Distribution was
     made, provided that the shares of NSU Common Stock are held as a capital
     asset on the Distribution Date; and (iv) where cash is received by a holder
     of NSU Common Stock pursuant to the Distribution in lieu of fractional
     share interests in NSU Common Stock, the cash payment will be treated as
     received by the holder of NSU Common Stock as a distribution in redemption
     of the fractional share interest and such shareholder will recognize gain
     or loss, subject to the provisions and limitations of Section 302 of the
     Code.
 
     Treasury regulations governing Section 355 of the Code require that each
NSU shareholder who receives shares of ENStar Common Stock pursuant to the
Distribution attach a statement to the federal income tax return that will be
filed by the shareholder for the taxable year in which such shareholder received
the shares of ENStar Common Stock, which statement shows the applicability of
Section 355 of the Code to the Distribution. ENStar has represented that it will
provide each ENStar shareholder with information necessary to comply with this
requirement.
 
     The rulings described above will be based upon certain representations,
including representations that (i) the holders of Michael Common Stock do not
have any plan or intention to sell, exchange or otherwise dispose of a number of
shares of New Michael Common Stock received pursuant to the Merger that would
reduce the ownership of New Michael Common Stock by all of the pre-Merger
holders of Michael Common Stock to a number of shares having a value, as of the
date of the Merger, of less than 50% of the value of all of the formerly
outstanding Michael Common Stock as of the same date and (ii) the holders of
ENStar Common Stock do not have any plan or intention to sell, exchange or
otherwise dispose of any of their ENStar or New Michael Common Stock following
and as part of the Distribution.
 
     Where cash is received by a holder of NSU Common Stock who exercises
dissenters' rights in connection with the Distribution, the cash payment will be
treated as received by the holder of NSU Common Stock as a distribution in
redemption of such shareholder's NSU Common Stock and such shareholder will
recognize gain or loss, subject to the provisions and limitations of Section 302
of the Code.
 
     The foregoing is only a general description of certain anticipated federal
income tax consequences of the Merger, Reverse Stock Split, and Distribution
without regard to the particular facts and circumstances of the tax situation of
each stockholder of Michael or shareholder of NSU. It does not discuss all of
the consequences that may be relevant to Michael's stockholders or NSU's
shareholders entitled to special treatment under the Code (such as insurance
companies, dealers in securities, exempt organizations or foreign persons) or to
shareholders of NSU or stockholders of Michael who acquired their NSU Common
Stock or Michael Common Stock pursuant to the exercise of employee stock options
or otherwise as compensation. The summary set forth above does not purport to be
a complete analysis of all potential tax effects of the transactions
contemplated by the Reorganization Agreement or the Merger itself or the
Distribution
 
                                       46
<PAGE>   55
 
Agreement or the Distribution itself. No information is provided herein with
respect to the tax consequences, if any, of the Merger, Reverse Stock Split or
Distribution under state, local or foreign tax laws.
 
THIS FEDERAL INCOME TAX DISCUSSION IS FOR GENERAL INFORMATION ONLY AND MAY NOT
APPLY TO ALL HOLDERS OF NSU COMMON STOCK OR TO ALL HOLDERS OF MICHAEL COMMON
STOCK. SUCH HOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE
SPECIFIC TAX CONSEQUENCES OF THE REORGANIZATION.
 
REGULATORY APPROVALS
 
   
     Antitrust. Under the HSR Act and the rules and regulations thereunder, the
Reorganization may not be consummated until notifications have been given and
certain information has been furnished to the Antitrust Division of the United
States Department of Justice (the "Antitrust Division") and the FTC and
specified waiting period requirements have been satisfied. NSU and Michael each
filed with the Antitrust Division and the FTC a Notification and Report Form
(the "Notification and Report Form") with respect to the Merger and the initial
waiting period for each of these filings expired at 11:59 p.m. on May 28, 1996.
    
 
LISTING OF NEW MICHAEL COMMON STOCK; DIVIDENDS
 
     New Michael expects to continue the Nasdaq National Market listing of NSU
Common Stock, but will use the symbol MIKL, rather than NSRU, and will
discontinue the listing of New Michael Common Stock on the Pacific Stock
Exchange. The payment of future dividends on New Michael Common Stock will be a
business decision to be made by the New Michael Board from time to time based
upon the results of operations and financial condition of New Michael and such
other factors as the New Michael Board considers relevant.
 
LISTING OF ENSTAR COMMON STOCK; DIVIDENDS
 
     ENStar has applied to have the ENStar Common Stock approved for quotation
on the Nasdaq National Market under the symbol "ENSR." Since ENStar will not
have been publicly traded prior to the Distribution, there can be no assurance
that an active market will develop or be sustained after the Distribution,
although NSU has been advised that certain market makers in NSU Common Stock
expect to make a market in ENStar Common Stock. Management of ENStar currently
intends to retain any earnings for use in its operations and does not anticipate
paying any cash dividends in the foreseeable future.
 
EFFECT ON STOCK OPTION PLANS
 
     The 1987 Incentive Stock Option Plan of Michael, the 1987 Non-Qualified
Stock Option Plan of Michael, the 1992 Stock Option Plan for Non-Employee
Directors of Michael, the 1994 Executive Incentive Plan, and the 1994 Executive
Performance Share Award Plan (the "Michael Stock Plans") and the Michael Options
will be assumed and adopted by New Michael in accordance with the terms of the
Michael Stock Plans and the Michael Options, and will have the rights provided
in such plans, which will remain unaffected by the Merger. New Michael will
reserve a sufficient number of authorized but unissued shares of New Michael
Common Stock for issuance under the Michael Stock Plans. As required pursuant to
the terms of the Reorganization Agreement, all outstanding NSU stock options
will be exercised or canceled by the Effective Date and all NSU stock option
plans will be terminated.
 
FEDERAL SECURITIES LAWS CONSEQUENCES
 
     All shares of New Michael Common Stock received by Michael stockholders and
NSU shareholders in the Merger, and all shares of ENStar Common Stock received
by NSU shareholders in the Distribution, will be freely transferable, except
that shares of New Michael Common Stock received by persons who are deemed to be
"affiliates" (as such term is defined under the Securities Act), of Michael or
NSU prior to the Merger and shares of ENStar Common Stock received by persons
who are deemed to be "affiliates" of NSU or ENStar may be resold by them only in
transactions permitted by the resale provisions of Rule 145 promulgated under
the Securities Act (or Rule 144 in the case of such persons who become
affiliates of New
 
                                       47
<PAGE>   56
 
Michael or ENStar) or as otherwise permitted under the Securities Act. Persons
who may be deemed to be affiliates of Michael, NSU, ENStar or New Michael
generally include individuals or entities that control, are controlled by, or
are under common control with, such party and may include certain officers and
directors of such party as well as principal stockholders of such party.
 
DISSENTERS' RIGHTS
 
     Under the Delaware General Corporation Law (the "DGCL"), holders of Michael
Common Stock are not entitled to dissenters' rights in connection with the
Merger because the Michael Common Stock is designated as a national market
system security on an interdealer quotation system by Nasdaq, Inc., and the
consideration which such holders will receive in the Merger consists solely of
New Michael Common Stock, which will also be designated as a national market
system security on an interdealer quotation system by Nasdaq, Inc.
 
     Holders of NSU Common Stock who do not vote in favor of the Distribution
and who have properly complied with Sections 302A.471 and 302A.473 of the MBCA
will be entitled to dissenters' rights. Under the Reorganization Agreement, NSU
is not required to complete the Merger if holders of 1% or more of the
outstanding NSU Common Stock effectively elect dissenters' rights.
 
     Shareholders of NSU that follow the procedures set forth in Section
302A.473 will be entitled to have their shares of NSU Common Stock appraised by
a Minnesota court and to receive payment of the "fair value" of such shares as
determined by that court. The shares of NSU Common Stock with respect to which
the holder has perfected a demand for dissenters' rights in accordance with
Section 302A.473 and has not effectively withdrawn or lost his rights to such
appraisal are referred to in this Proxy Statement/Prospectus as the "Dissenting
Shares."
 
   
     Section 302A.473 entitles any holder of the NSU Common Stock who objects to
the Distribution, in lieu of receiving securities to which he or she would be
entitled to under the Reorganization Agreement and the Distribution Agreement,
to dissent therefrom and obtain payment for the "fair value" of his or her
shares of NSU Common Stock. Any shareholder of NSU contemplating the exercise of
these dissenters' rights should carefully review the provisions of Sections
302A.473 of the MBCA which has been provided as Appendix IV to this Proxy
Statement/Prospectus, particularly the specific procedural steps to perfect such
rights. SUCH RIGHTS WILL BE LOST IF THE PROCEDURAL REQUIREMENTS OF SECTION
302A.473 ARE NOT FULLY AND PRECISELY SATISFIED. Subject to the more complete
description below, the procedural requirements for the exercise of dissenters'
rights can be summarized as follows: (i) the dissenting NSU shareholder must
file with NSU before the vote on the Reorganization a written notice of intent
to demand the fair value of his or her shares of NSU Common Stock; (ii) the
shareholder must not vote in favor of the Reorganization; (iii) if the
Reorganization is approved, the shareholder must demand payment for his or her
shares of NSU Common Stock and deposit the certificates representing such shares
with New Michael; (iv) New Michael will estimate the fair value of such shares
and pay the shareholder an amount equal to such value; and (v) if the NSU
dissenting shareholder disagrees with the estimate of such value, the
shareholder must demand payment from New Michael of the difference between the
amount claimed to be the fair value and the amount paid, which, if not agreed to
by Michael, will be submitted for determination by a Minnesota court.
    
 
     Set forth below (to be read in conjunction with the full text of Section
302A.473 included with this Proxy Statement/Prospectus) is a brief description
of the procedures relating to the exercise of dissenters' rights. The following
description does not purport to be a complete statement of the provisions of
Section 302A.473 and is qualified in its entirety by reference thereto.
 
     Under Section 302A.473, Subd. 3, a shareholder of NSU who wishes to
exercise dissenters' rights (a "Dissenter") must file with NSU at Suite 610,
Park National Bank Building, 5353 Wayzata Blvd., Minneapolis, Minnesota 55416
before the vote on the NSU Proposals, a written notice of intent to demand the
"fair value" of NSU Common Stock owned by such shareholder. A shareholder of NSU
may not assert dissenters' rights as to less than all of the shares registered
in the name of such shareholder unless that shareholder dissents with respect to
all the shares that are beneficially owned by another person but registered
 
                                       48
<PAGE>   57
 
in the name of such shareholder and discloses the name and address of each
beneficial owner on whose behalf such shareholder dissents. In that event, the
rights of the Dissenter shall be determined as if the shares as to which such
shareholder dissented and the other shares were registered in the names of
different shareholders. A beneficial owner of shares of NSU Common Stock who is
not the record holder may assert dissenters' rights with respect to shares held
on behalf of the beneficial owner, and shall be treated as a Dissenter, if the
beneficial owner submits to NSU a written consent of the record holder of such
shares. IN ADDITION, THE SHAREHOLDER MUST NOT VOTE HIS OR HER SHARES IN FAVOR OF
THE DISTRIBUTION. A VOTE AGAINST SUCH PROPOSAL WILL NOT IN ITSELF CONSTITUTE
SUCH A WRITTEN NOTICE AND A FAILURE TO VOTE WILL NOT AFFECT THE VALIDITY OF A
TIMELY WRITTEN NOTICE. HOWEVER, THE SUBMISSION OF A BLANK PROXY WILL CONSTITUTE
A VOTE IN FAVOR OF SUCH PROPOSAL AND A WAIVER OF STATUTORY DISSENTERS' RIGHTS.
 
     If the Distribution is approved by the shareholders of NSU, New Michael
will send to all Dissenters who file the necessary notice of intent to demand
the fair value of their shares and who did not vote their shares in favor of
such proposals, a notice containing certain information required by Section
302A.473, Subd. 4, including without limitation the address to which a Dissenter
must send a demand for payment and certificates representing shares in order to
obtain payment for such shares and the date by which they must be received. In
order to receive the fair value of the shares under Section 302A.473, a
Dissenter must demand payment and deposit certificates representing shares of
NSU Common Stock within 30 days after such notice from New Michael is given.
Under Minnesota law, notice by mail is given by New Michael when deposited in
the United States mail. A SHAREHOLDER WHO FAILS TO MAKE DEMAND FOR PAYMENT AND
TO DEPOSIT CERTIFICATES AS REQUIRED BY SECTION 302A.473, SUBD. 4, WILL LOSE THE
RIGHT TO RECEIVE THE FAIR VALUE OF HIS OR HER SHARES UNDER SUCH SECTION
NOTWITHSTANDING THE TIMELY FILING OF NOTICE OF INTENT TO DEMAND PAYMENT UNDER
SECTION 302A.473, SUBD. 3.
 
     Except as provided below, if demand for payment and deposit of stock
certificates is duly made by a Dissenter with New Michael as required by the
notice, then after the Effective Time or the receipt of the demand, whichever is
later, New Michael will pay the Dissenter an amount that New Michael estimates
to be the fair value of the Dissenter's shares of NSU Common Stock, with
interest, if any. Under Sections 302A.471 and 302A.473, "fair value" means the
value of the shares of NSU Common Stock immediately before the Effective Time
and "interest" means interest commencing five days after the Effective Date
until the time of payment, calculated at the rate provided in Minnesota Statutes
Section 549.09. If the Dissenter believes the payment received from New Michael
is less than the fair value of the shares of NSU Common Stock, with interest, if
any, such Dissenter must give written notice to New Michael of his or her own
estimate of the fair value of the shares of NSU Common Stock, with interest, if
any, within 30 days after the date of New Michael's remittance, and must demand
payment of the difference between his or her estimate and New Michael's
remittance. If the Dissenter fails to give written notice of such estimate to
New Michael within the 30-day time period, such Dissenter will be entitled only
to the amount remitted by New Michael.
 
     New Michael may withhold such remittance with respect to shares of NSU
Common Stock for which the Dissenter demanding payment (or persons on whose
behalf such Dissenter acts) was not the beneficial owner as of December 21,
1995, the first public announcement date of the Merger (the "Public Announcement
Date"). As to each Dissenter who has validly demanded payment, following the
Effective Time or the receipt of demand, whichever is later, New Michael will
mail its estimate of the fair market value of such Dissenter's shares of NSU
Common Stock and offer to pay this amount with interest, if any, to the
Dissenter upon receipt of such Dissenter's agreement to accept this amount in
full satisfaction. If such Dissenter believes that New Michael's offer is less
than the fair value of the shares of NSU Common Stock, with interest, if any,
such Dissenter must give written notice to New Michael of his or her own
estimate of the fair value of the shares of NSU Common Stock with interest, if
any, and demand payment of this amount. This demand must be mailed to New
Michael within 30 days after the mailing of New Michael's offer. If the
Dissenter fails to make this demand within such 30 day time period, such
Dissenter shall be entitled only to the amount offered by New Michael.
 
                                       49
<PAGE>   58
 
     If New Michael and the Dissenter cannot reach a settlement within 60 days
after New Michael receives the Dissenter's estimate of the fair value of his or
her shares of NSU Common Stock, then New Michael must file a petition in the
district court of Hennepin County, Minnesota, requesting that the court
determine the statutory fair value of the NSU Common Stock, with interest, if
any. All Dissenters whose demands are not settled within the applicable 60-day
settlement period will be made parties to this proceeding.
 
     The court will then determine whether each Dissenter in question has fully
complied with the provisions of Section 302A.473, and for all Dissenters who
have fully complied and not forfeited statutory dissenters' rights, will
determine the fair value of the Dissenters' shares, taking into account any and
all factors the court finds relevant (including, without limitation, the
recommendation of any appraisers that may have been appointed by the court),
computed by any method that the court, in its discretion, sees fit to use,
whether or not used by New Michael or a Dissenter. The fair value of the
Dissenters' shares as determined by the court is binding on all shareholders and
may be less than, equal to or greater than the consideration to the holders if
the Reorganization is completed. However, under the statute, Dissenters are not
liable to New Michael for the amount, if any, by which payments remitted to the
Dissenters exceed the fair value of such shares determined by the court, with
interest. The costs and expenses of this court proceeding will be assessed
against New Michael, except that the court may assess part or all of such costs
and expenses against a Dissenter whose action in demanding payment is found to
be arbitrary, vexatious or not in good faith.
 
     Under Section 302A.471, Subd. 4, a shareholder of NSU has no right at law
or equity to set aside the consummation of the Merger, the Reverse Stock Split,
the Distribution or the New Articles, unless the adoption thereof is fraudulent
with respect to such shareholder or NSU.
 
     FAILURE TO FOLLOW THE STEPS REQUIRED BY SECTION 302A.473 FOR PERFECTING
DISSENTERS' RIGHTS MAY RESULT IN THE LOSS OF SUCH RIGHTS. IN VIEW OF THE
COMPLEXITY OF THE PROVISIONS OF SECTION 302A.473, SHAREHOLDERS OF NSU WHO ARE
CONSIDERING DISSENTING FROM THE DISTRIBUTION SHOULD CONSULT THEIR OWN LEGAL
ADVISORS.
 
     NSU shareholders considering exercising dissenters' rights should bear in
mind that the fair value of their NSU Common Stock determined under Section
302A.473 could be more than, the same as or less than the value of the
consideration they will receive pursuant to the Reorganization Agreement if they
do not exercise dissenters' rights. In addition, in most cases, NSU shareholders
who receive cash for the fair value of their shares of NSU Common Stock upon the
exercise of dissenters' rights will realize taxable gain or loss for federal
income tax purposes. EACH SHAREHOLDER OF NSU IS URGED TO CONSULT WITH HIS OR HER
OWN PERSONAL TAX AND FINANCIAL ADVISORS CONCERNING FEDERAL INCOME TAX
CONSEQUENCES OF THE EXERCISE OF DISSENTERS' RIGHTS, AS WELL AS ANY APPLICABLE
STATE, LOCAL, FOREIGN OR OTHER TAX CONSEQUENCES, BASED UPON SUCH SHAREHOLDER'S
OWN PARTICULAR FACTS AND CIRCUMSTANCES.
 
                          THE REORGANIZATION AGREEMENT
 
     The following information describes certain aspects of the Reorganization
Agreement. This description does not purport to be complete and is qualified in
its entirety by reference to the Appendices hereto, including the Reorganization
Agreement and exhibits thereto, which are attached to this Proxy
Statement/Prospectus as Appendix I and are incorporated herein by reference. All
stockholders are urged to read Appendix I in its entirety. See also "THE
DISTRIBUTION AGREEMENT."
 
GENERAL
 
   
     The Reorganization Agreement provides that: (i) Merger Co. will be merged
with and into Michael and Michael will become a wholly-owned subsidiary of NSU;
(ii) in the Merger, each stockholder of Michael (other than NSU) will receive,
in exchange for each share of Michael Common Stock held by such stockholder, one
share of New Michael Common Stock; (iii) each share of Michael Common Stock held
by NSU will be canceled and retired; (iv) NSU will change its name to Michael
Foods, Inc. and will continue the business previously conducted by Michael
(Michael will change its name to Michael Foods of Delaware, Inc.); (v) prior to
the consummation of the Merger, NSU will transfer to ENStar all of its assets
and liabilities other than certain indebtedness and cash, as determined by NSU
and other agreed upon assets and
    
 
                                       50
<PAGE>   59
 
   
liabilities; (vi) the outstanding common stock of ENStar will, conditioned upon
the consummation of the Merger, be distributed pro rata to the shareholders of
NSU of record as of a record date just prior to the Effective Date; and (vii)
immediately prior to the Effective Time, NSU will effectuate the Reverse Stock
Split. The ratio of the Reverse Stock Split will be determined pursuant to the
terms of the Reorganization Agreement in the manner described below. See also
"THE REORGANIZATION -- Effects of the Reorganization."
    
 
EFFECTS OF THE REORGANIZATION ON THE STOCKHOLDERS OF MICHAEL AND THE
SHAREHOLDERS OF NSU
 
   
     Michael Stockholders. Upon consummation of the Merger, each outstanding
share of Michael Common Stock, other than the Michael Common Stock owned by NSU,
will be converted into the right to receive one share of New Michael Common
Stock. Upon the consummation of the Merger, each outstanding share of Michael
Common Stock owned by NSU will be canceled and retired without any payment
therefor.
    
 
     On and after the Effective Date, and until surrendered for exchange, each
outstanding stock certificate which immediately prior to the Effective Time
represented shares of Michael Common Stock will be deemed for all purposes to
evidence ownership of and to represent the same number of whole shares of New
Michael Common Stock and the record holder of such outstanding certificate will,
after the Effective Date, be entitled to vote the shares of New Michael Common
Stock into which such shares of Michael Common Stock will have been converted on
any matters on which the holders of record of the New Michael Common Stock, as
of any date subsequent to the Effective Date, are entitled to vote. In any
matters relating to such certificates of Michael Common Stock, New Michael may
rely conclusively upon the record of stockholders maintained by Michael or its
agent containing the names and addresses of the holders of record of Michael
Common Stock on the Effective Time.
 
   
     NSU Shareholders. On the Effective Date, immediately prior to the Effective
Time, but in any event subject to the consummation of the Merger, NSU will
effectuate the Reverse Stock Split. In the Reverse Stock Split, each outstanding
share of NSU Common Stock will be converted into a fraction of one share of New
Michael Common Stock determined by multiplying each such share by a fraction
where the denominator is the number of outstanding shares of NSU Common Stock
immediately prior to the Effective Date and the numerator is the number of
shares of Michael Common Stock owned by NSU at such date less the Retired
Michael Shares. For purposes of the Reorganization Agreement, Net Indebtedness
is defined to be the amount of outstanding NSU subordinated debentures and fixed
or extendible time certificates and the Dissenting Shares Holdback less cash
retained by New Michael. The Dissenting Shares Holdback is an amount to be
mutually agreed upon by NSU and Michael based on the number of Dissenting
Shares. Under the terms of the Reorganization Agreement, NSU has indicated to
Michael that the Net Indebtedness to be retained by New Michael, excluding the
amount of the Dissenting Shares Holdback, will not be less than $25 million nor
more than $29 million. NSU has also otherwise indicated that it intends to
retain cash in an amount at least equal to the Dissenting Shares Holdback such
that the Net Indebtedness will be between $25 million and $29 million. The
number of shares of Michael Common Stock effectively retired as a result of the
Reorganization in consideration for the Net Indebtedness will be determined by
dividing the amount of Net Indebtedness by the Average Price of Michael Common
Stock after applying a certain percentage discount to the Average Price of
Michael Common Stock. The Discount Factor will be based upon the amount of Net
Indebtedness, ranging from 92% at $25 million to 91% beginning at $28.75
million, resulting in an effective discount of between 8% and 9%. The Discount
Factor is determined pursuant to Exhibit A to the Reorganization Agreement, a
copy of which is included in Appendix I to this Proxy Statement/Prospectus.
    
 
     Pursuant to the Distribution Agreement between NSU and ENStar, prior to the
Merger, NSU will contribute and transfer to ENStar, all of NSU's assets, other
than: (i) such amount of cash as NSU may, in its sole discretion, determine to
retain at the Effective Date; (ii) 7,354,950 shares of Michael Common Stock
owned by NSU; (iii) the capital stock of Merger Co.; (iv) the rights of NSU
under the Reorganization Agreement, the Distribution Agreement and the Orderly
Disposition Agreement; and (v) all net operating loss carryforwards and other
tax attributes properly allocable to NSU following the Effective Date in
accordance with the relevant provisions of the Code (the "NSU Retained Assets").
ENStar also will assume all NSU liabilities other than: (i) liabilities arising
from assertion of dissenters' rights by NSU shareholders,
 
                                       51
<PAGE>   60
 
(ii) liabilities under the Reorganization Agreement, the Distribution Agreement
or the Orderly Disposition Agreement; and (iii) NSU's indebtedness (including
principal and accrued interest, the "NSU Indebtedness") represented by NSU's
outstanding subordinated debentures, subordinated extendible time certificates,
subordinated fixed time certificates and bank debt (collectively, the "NSU
Assumed Liabilities"). In addition, with certain limited exceptions, all
intercompany receivables, payables and loans in existence as of the Effective
Time between NSU and any NSU subsidiary, will be eliminated, without the
transfer of cash, by dividend or capital contributions, as appropriate.
 
     On or prior to the Effective Date, NSU will deliver to its transfer agent
certificates representing all of the outstanding shares of ENStar Common Stock.
On the Effective Date, immediately after the Effective Time, NSU will deliver to
such transfer agent an instruction to distribute as promptly as practicable
following the Effective Date to each holder of record of NSU Common Stock on the
record date for the Distribution stock certificates evidencing one share of
ENStar Common Stock for every three shares of NSU Common Stock held of record by
such shareholder on such record date for the Distribution and cash in lieu of
any fractional shares of ENStar Common Stock. No certificate or scrip
representing fractional shares of ENStar Common Stock will be issued as part of
the Distribution, and in lieu of receiving fractional shares each holder of NSU
Common Stock who would otherwise be entitled to receive a fractional share of
ENStar Common Stock pursuant to the Distribution will receive cash for such
fractional share.
 
NEW MICHAEL MANAGEMENT FOLLOWING THE REORGANIZATION
 
     The Board of Directors of New Michael (the "New Michael Board") after the
Merger will consist of nine members, seven of whom will be designated by the
Michael Board. These designees are expected to include Gregg A. Ostrander,
Richard A. Coonrod, Arvid C. Knudtson, Joseph D. Marshburn, Richard G. Olson,
and             . There will initially be one vacancy on the New Michael Board.
An additional director is expected to be appointed by the New Michael Board
after the Effective Date. See "ELECTION OF MICHAEL DIRECTORS -- Nominees" for
further information on the named individuals. Two additional directors are
expected to be Jeffrey J. Michael and Miles E. Efron or other substitute
nominees of the Michael Family Shareholders, if either Mr. Michael or Mr. Efron
are unable to serve. Messrs. Michael and Efron currently are directors of
Michael. NSU and Michael currently contemplate that the members of the NSU Board
other than Mr. Efron and Mr. Michael will resign as of the Effective Time and
Mr. Efron and Mr. Michael will name the above-referenced individuals to the New
Michael Board. The New Michael Board will elect the officers of Michael as the
officers of New Michael. The officers of New Michael will be the officers of
Michael on the Effective Date.

CERTAIN COVENANTS
 
     Conduct of Business by NSU. The Reorganization Agreement provides that
until the Effective Date, unless Michael otherwise agrees in writing or as
otherwise expressly contemplated or permitted by other provisions of the
Reorganization Agreement, NSU will not, directly or indirectly: (i) amend or
propose to amend its Articles or Bylaws except for the New Articles; (ii) issue,
sell or grant any of its equity securities other than NSU Common Stock,
securities convertible into or exchangeable for its equity securities other than
NSU Common Stock, warrants, options or other rights to acquire its equity
securities other than NSU Common Stock; (iii) reclassify any outstanding shares
of capital stock of NSU; (iv) acquire (by merger, exchange, consolidation,
acquisition of stock or assets or otherwise) any corporation, partnership, joint
venture or other business organization or division or assets thereof, except by
a NSU subsidiary and in a transaction in which NSU shall not have any
liabilities with respect thereto after the Effective Time; (v) sell, transfer,
pledge or otherwise encumber the Michael Common Stock owned by NSU other than as
collateral for indebtedness under a certain credit agreement; (vi) purchase or
otherwise acquire any additional shares of Michael Common Stock; (vii) default
in its obligations under any material debt, contract or commitment which default
results in the acceleration of obligations due thereunder; or (viii) enter into
or propose to enter into, or modify or propose to modify, any agreement,
arrangement, or understanding with respect to any of the foregoing matters.
 
     Conduct of Business by Michael. The Reorganization Agreement provides that
until the Effective Date, unless NSU otherwise agrees in writing or as otherwise
expressly contemplated or permitted by other provisions of the Reorganization
Agreement, Michael will not, directly or indirectly: (i) amend its charter or
bylaws; (ii) split, combine or reclassify any outstanding shares of capital
stock of Michael; (iii) declare, set aside, make or pay any dividend or
distribution in cash, stock, property or otherwise with respect to the capital
stock of Michael, except for regular quarterly dividends which are not in excess
of $.05 per share per quarter on the Michael Common Stock, or (iv) default in
its obligations under any material debt, contract or commitment which default
results in the acceleration of obligations due thereunder, except for such
defaults arising out of the Reorganization Agreement for which consent, waivers
or modifications are required to be obtained.
 
     Conditions and Undertakings. The Reorganization Agreement contains a number
of undertakings that must be completed by the parties prior to the Effective
Date and other agreements. The parties agreed to cooperate in the filing of a
ruling request with the IRS and an HSR notification. NSU also agreed to enter
into the Distribution Agreement. NSU is required to notify Michael of the
anticipated Net Indebtedness within a range of plus or minus $2,000,000 prior to
the effectiveness of the Registration Statement. In addition, the parties agreed
to retain certain information in confidence and to take appropriate action to
complete the Reorganization.
 
TERMINATION
 
     The Reorganization Agreement may be terminated prior to the Effective Date
under the following conditions: (i) by mutual consent of Michael and NSU, by
majority vote of the entire board of directors of each; (ii) by either Michael
or NSU, if any of the conditions to its obligation to consummate the
transactions
 
                                       54
<PAGE>   63
 
contemplated by the Reorganization Agreement have become impossible to satisfy;
(iii) by either Michael or NSU, if (a) the Merger is not duly approved by the
stockholders of Michael; or (b) any one of the NSU Proposals is not approved by
the shareholders of NSU; (iv) by either Michael or NSU if the Effective Date is
not on or before September 30, 1996 or such later date as Michael and NSU may
mutually agree (unless the failure to consummate the Merger by such date shall
be due to the action or failure to act of the party seeking to terminate the
Merger in breach of such party's obligations); (v) by NSU if the Average Price
of Michael Common Stock is less than $11.00 per share; (vi) by Michael if the
Average Price of Michael Common Stock is more than $17.00 per share; or (vii) by
Michael or NSU after notice and an opportunity to cure if a representation or
warranty given by the other is updated in such a way to indicate that the party
making such update will suffer a material adverse effect or material liability.
 
EXPENSES
 
     Except as provided below, all costs and expenses incurred in connection
with the Merger will be paid by the party incurring the cost or expense. NSU and
Michael will each pay one-half of (i) all filing fees required to be paid under
the HSR Act in connection with the Merger (but excluding any HSR filing in
connection with the Distribution), (ii) all cost of filing fees with respect to
the NSU Registration Statement, and (iii) all costs of qualifying New Michael
Common Stock to be issued in the Reorganization under state blue sky laws to the
extent such qualification is necessary.
 
     In the event the Reorganization Agreement is properly terminated: (i) by
Michael or NSU due to the failure of NSU to obtain the requisite shareholder
approval for the NSU Proposals; (ii) by Michael due to the failure by NSU to
satisfy certain conditions or if any of NSU's warranties and representations are
not true and correct and the failure to be true and correct would have a
material adverse effect on NSU; (iii) by NSU if the Average Price of Michael
Common Stock is less than $11.00 per share; (iv) by Michael if a representation
or warranty given by NSU in the Reorganization Agreement is updated in such a
way that the information indicates that NSU has suffered or will suffer a
material adverse effect, or in the case of NSU's representation in the
Reorganization Agreement regarding NSU's liabilities as of the Effective Time,
Michael determines that NSU has suffered or will suffer a material liability,
which has not been cured within 15 days after notice to NSU of Michael's intent
to terminate because of the updated information; or (v) by NSU if holders of in
excess of 1% of the outstanding NSU Common Stock effectively exercise
dissenters' rights, then, within ten days after written demand from Michael, NSU
will pay to Michael an amount equal to the out of pocket expenses incurred by
Michael in connection with the transactions contemplated by the Reorganization
Agreement, up to an aggregate of $500,000, payable either, at the option of NSU,
in cash or in shares of Michael Common Stock having a fair market value
(determined on the basis of the average closing sales price of Michael Common
Stock during the twenty trading days immediately preceding such termination)
equal to such amount.

representations are not true and correct, and the failure to be true and correct
would have a material adverse effect on Michael; (iii) by Michael if the Average
Price of Michael Common Stock is more than $17.00 per share; (iv) by NSU after
notice to Michael and an opportunity to cure if a representation or warranty
given by Michael in the Reorganization Agreement is updated in such a way that
the information indicates that Michael has suffered or will suffer a material
adverse effect or material liability; or (v) the transactions contemplated by
this Agreement are not consummated solely because Michael has not obtained the
necessary modifications to its material debt instruments or prepaid such debt
instruments, then, within ten days after written demand from NSU, Michael must
pay to NSU an amount equal to the out of pocket expenses incurred by NSU in
connection with the transactions contemplated by this Agreement, up to an
aggregate of $500,000, payable either in cash, or in shares of Michael Common
Stock having a fair market value (determined on the basis of the average closing

                           THE DISTRIBUTION AGREEMENT
 
     The following information describes certain aspects of the Distribution
Agreement. This description does not purport to be complete and is qualified in
its entirety by reference to the Appendices hereto, including the Reorganization
Agreement and the exhibits thereto, which is attached to this Proxy
Statement/Prospectus as Appendix I and is incorporated herein by reference and
the Distribution Agreement, which is attached to the Reorganization Agreement as
Exhibit C. All Michael stockholders and NSU shareholders are urged to read
Appendix I in its entirety. See also "THE REORGANIZATION AGREEMENT."
 
GENERAL
 
     The Reorganization Agreement provides that NSU will, and will cause ENStar
to, execute and deliver the Distribution Agreement prior to the Effective Date.
The Distribution Agreement requires NSU to contribute and transfer to ENStar or
a ENStar subsidiary, as appropriate, all of NSU's assets (the "NSU Transferred
Assets"), except for the NSU Retained Assets. In addition, ENStar will assume
all liabilities of NSU (i) arising at any time prior to the Merger Effective
Date, other than the NSU Assumed Liabilities, or (ii) arising as a result of the
Distribution other than the NSU Assumed Liabilities (the NSU Transferred
Liabilities"). With certain limited exceptions, all intercompany receivables,
payables and loans between NSU and any NSU subsidiary in existence as of the
Effective Date will be eliminated.
 
     In the Distribution Agreement, ENStar acknowledges that NSU is not
representing or warranting in any way (i) as to the value or freedom from
encumbrance of, or any other matter concerning, any NSU Transferred Assets or
(ii) as to the legal sufficiency to convey title to any such assets or the
execution and delivery of the Distribution Agreement. All such assets are being
transferred as is, where is, and ENStar will bear all economic and legal risks
with respect to the NSU Transferred Assets.
 
CONDITIONS
 
     The Distribution is expressly conditioned on the prior consummation of the
Merger. The Distribution will not occur (i) if, on the Effective Date, NSU has
not received an opinion of tax counsel or a private letter ruling from the IRS
to the effect that the Distribution will qualify as a tax-free spin-off under
Section 355 of the Code, and (ii) unless prior to such time the following
conditions have been satisfied or waived: (a) the transfer of the NSU
Transferred Assets to and the assumption of the NSU Transferred Liabilities by
ENStar has been completed, (b) the ENStar Common Stock has been approved for
quotation on the Nasdaq National Market or listing on a national securities
exchange, (c) the ENStar Board has been elected by NSU, as sole shareholder of
ENStar; (d) the ENStar Registration Statement has been declared effective by the
Commission and the Form 8-A relating to the shares of ENStar Common Stock to be
distributed in the Distribution has become effective under the Exchange Act; and
(e) all conditions precedent to the obligations of NSU and Michael under the
Reorganization Agreement (other than consummation of the Distribution) will have
been satisfied or waived and the Merger has been consummated.
 
THE DISTRIBUTION
 
     On or prior to the Effective Date, NSU will deliver to its transfer agent
certificates representing all of the outstanding shares of ENStar Common Stock.
On the Effective Date, immediately after the Effective Time, NSU will deliver to
such transfer agent an instruction to distribute as promptly as practicable
following the Effective Date to each holder of record of NSU Common Stock on the
record date for the Distribution stock certificates evidencing one share of
ENStar Common Stock for every three shares of NSU Common Stock held of record by
such shareholder on such record date for the Distribution and cash in lieu of
any fractional shares of ENStar Common Stock. No certificate or scrip
representing fractional shares of ENStar Common Stock will be issued as part of
the Distribution, and in lieu of receiving fractional shares each such holder of
NSU Common Stock pursuant to the Distribution will receive cash for such
fractional share. If the number of
 
                                       56
<PAGE>   65
 
outstanding shares of ENStar Common Stock exceeds the amount to be distributed
in the Distribution, then the remaining shares will be deemed to have been
contributed by NSU to the capital of ENStar and retired and canceled. All of the
shares of ENStar Common Stock issued in the Distribution will be fully paid,
nonassessable and free of preemptive rights.
 
CERTAIN COVENANTS
 
     The Distribution Agreement provides that New Michael will not, nor will it
permit Michael to do any of the following during the two year period following
the Effective Date: (i) liquidate Michael; (ii) merge Michael with or into
another corporation, unless Michael is the surviving corporation and the merger
is not treated for tax purposes as a sale or other disposition of Michael Common
Stock; (iii) sell any shares of Michael Common Stock or cause Michael to issue
any shares of Michael Common Stock to any party other than NSU; or (iv) sell any
assets of New Michael to any third party not otherwise an affiliate of the
foregoing, except for (a) sales in the ordinary course of business or (b) sales
of assets if, after giving effect to such sales, Michael will retain at least
90% of the fair market value of its gross assets in active trades or businesses
within the meaning of Section 355 of the Code; provided, however, New Michael or
Michael may undertake any of the actions listed above if (1) ENStar consents
thereto or (2) New Michael obtains either a tax opinion or a favorable private
letter ruling from the IRS, in each case reasonably satisfactory to ENStar, to
the effect that the actions to be undertaken would not adversely affect the tax
free nature of the Merger or the Distribution to all of the parties thereto. The
shareholders of record of NSU on the record date for the Distribution are third
party beneficiaries of the foregoing restrictions.
 
     ENStar and NSU have agreed in the Distribution Agreement that, on or prior
to the Distribution Date, to the extent required under any indenture with
respect to any of the outstanding debentures or any of the outstanding
subordinated extendible or fixed time certificates of NSU, they will execute and
deliver supplemental indentures or other agreements or instruments evidencing
ENStar's assumption of NSU's obligations with respect to such outstanding
debentures and subordinated extendible and fixed time certificates; provided,
however, that as between NSU and ENStar, the NSU Indebtedness is not considered
an NSU Transferred Liability and New Michael, after the Effective Time, shall be
responsible for the payment in full, in accordance with the terms thereof of all
of the NSU Indebtedness and shall indemnify ENStar for any and all liabilities
with respect to the NSU Indebtedness.
 
INDEMNIFICATION
 
     From and after the Effective Date, ENStar will indemnify New Michael,
Michael and all Michael subsidiaries and Merger Co. against: (i) all liabilities
(other than the NSU Assumed Liabilities) of NSU or any NSU subsidiary (other
than Michael and its Subsidiaries), including any subsidiary owned by NSU prior
to the Effective Date but not owned by NSU on the Merger Effective Date, arising
out of: (a) the NSU Transferred Liabilities, and (b) the transactions
contemplated under the Distribution Agreement, including the Distribution and
any taxes as a result of the Distribution (other than (X) any liabilities
resulting from any breach by New Michael, after the Effective Date, of the
Distribution Agreement, (Y) any liability of NSU for taxes resulting from a
breach by New Michael of the restrictions set forth above relating to the two
year period after the Effective Date, and (Z) obligations, after the Effective
Date, expressly assumed by New Michael under the Distribution Agreement); (ii)
all liabilities arising from any claim made by any shareholder of ENStar on or
after the Effective Date or by any shareholder or former shareholder of NSU
prior to the Effective Date relating to any act or omission of NSU on or prior
to the Effective Date in connection with the Merger or any of the other
transactions as contemplated by the Reorganization Agreement; (iii) all
liabilities assumed by ENStar in the Distribution Agreement relating to the
employee benefit plans of NSU; (iv) all liabilities of ENStar or any subsidiary
of ENStar arising out of transactions or events entered into or occurring after
the Effective Date, or any action or inaction, including but not limited to,
contracts, commitments and litigation, with respect to, entered into or based
upon transactions or events occurring after the Effective Date with respect to
ENStar or any subsidiary of ENStar (other than the NSU Assumed Liabilities); (v)
any breach of the Distribution Agreement by ENStar or any subsidiary of ENStar
after the Effective Date; and
 
                                       57
<PAGE>   66
 
(vi) damages, costs, and expenses including attorney's fees incurred in
defending and settling claims for such liabilities.
 
     From and after the Effective Date, New Michael will indemnify ENStar and
any ENStar subsidiary against: (i) all liabilities of New Michael, Michael or
any subsidiary of New Michael or Michael arising out of transactions or events
entered into or occurring after the Effective Date, or any action or inaction,
including but not limited to, contracts, commitments and litigation, with
respect to, entered into or based upon transactions or events occurring after
the Effective Date with respect to New Michael, Michael, any subsidiary of New
Michael after the Effective Date or any subsidiary of Michael, other than any
liability arising out of the NSU Transferred Liabilities; (ii) all liabilities
relating to the NSU Assumed Liabilities; (iii) all liabilities of Michael or any
subsidiary of Michael arising before, on or after the Merger Effective Date;
(iv) all liabilities arising from any claim made by any current or former
Michael stockholder or shareholder of New Michael after the Effective Date who
was a Michael stockholder or NSU shareholder immediately prior to the Effective
Date relating to any act or omission of Michael in connection with the Merger or
any of the other transactions contemplated in the Reorganization Agreement or
the Distribution Agreement; (v) any breach of the Distribution Agreement by New
Michael after the Merger Effective Date; and (vi) damages, costs and expenses
including attorney's fees incurred in defending and settling claims for such
obligations, expenses or liabilities.
 
     The Distribution Agreement provides for certain procedures for the parties
to assert claims for indemnification thereunder, including the mediation and
arbitration of disputes arising under the Distribution Agreement. In the event
that New Michael realizes a benefit in the form of a reduction in the federal or
state income taxes which New Michael would otherwise be obligated to pay, as a
result of the net operating loss carryforwards properly allocable to New Michael
from all tax periods prior to or ending on the Effective Date, ENStar has the
right to set-off the amount of any such tax savings against any liability of
ENStar under the Distribution Agreement (including the indemnification
obligations described above).
 
     In order to provide for the required payments to be made to satisfy
Dissenters' claims, New Michael will retain cash in an amount to be agreed upon,
in excess of the cash applied to NSU's indebtedness. Any cash not used for this
purpose will be delivered to ENStar after payment of all Dissenters' claims.
ENStar also is required to pay or cause the release of New Michael from certain
obligations of NSU under certain leases and NSU's guarantee of indebtedness of a
subsidiary of NSU within three years after the Effective Date (the date of the
release of such obligations, the "Release Date").
 
     In order to further provide that ENStar will be able to meet its
indemnification obligations to New Michael under the Distribution Agreement,
ENStar has agreed in the Distribution Agreement that it will not: (i) pay any
dividends, whether in cash or in property, or make any other distribution to its
shareholders, or redeem any of its capital stock for cash or property; (ii)
sell, transfer or dispose of any material amount of its assets in a single
transaction or related series of transactions, except in the ordinary course of
its business or for fair value; or (iii) sell, transfer or dispose of all or
substantially all of its assets or engage in any merger, consolidation or
reorganization unless (a) in the case of the sale, transfer or other disposition
of all or substantially all of its assets, the purchaser assumes the obligations
of ENStar (jointly and severally with ENStar) under the Distribution Agreement,
(b) in the case of a merger, consolidation or reorganization, the surviving
entity assumes the obligations of ENStar under the Distribution Agreement, or
(c) the Market Value (as defined below) of ENStar immediately after giving
effect to such dividend, distribution, redemption or other transaction is at
least equal to the following amounts during the following periods: (X)
$9,000,000 during the period beginning on the Effective Date and continuing to
the later to occur of (a) the Release Date or (b) the third anniversary of the
Effective Date; (Y) $3,000,000 during the period from the end of the period
referenced in clause (X) above and continuing to the fifth anniversary of the
Effective Date. The term "Market Value" is defined in the Distribution Agreement
as the greater of: (a) the market capitalization of ENStar's outstanding equity
securities, if ENStar is a publicly traded company, or (b) the net book value of
ENStar computed in accordance with generally accepted accounting principles,
except that securities owned by ENStar which are publicly traded shall be valued
at their market value without any adjustment for lack of liquidity or control
premium, but reduced for any taxes payable on the disposition of such
securities, taking
 
                                       58
<PAGE>   67
 
into account any and all tax benefits available to ENStar and using ENStar's
then applicable effective tax rate for purposes of such calculations.
 
     Under the Distribution Agreement, New Michael is required to repay in full
all of the NSU Indebtedness not later than six months after the Effective Date.
All such repayments (excluding any payments made with respect to any instruments
that have matured or otherwise become due and payable in accordance with their
respective terms prior to such repayment date) are to be effected on or about
the same date.

          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS
 
     The following Unaudited Pro Forma Condensed Combined Financial Statements

liabilities, other than certain indebtedness, to ENStar. The combined historical
net assets and results of the entities that NSU will contribute to ENStar are
contained in the columns labeled ENStar Historical.
 
   
     The pro forma balance sheet and pro forma statements of earnings of NSU
give effect to the Distribution as if the Distribution had occurred at March 31,
1996 and January 1, 1995 and 1996, respectively. The unaudited pro forma
condensed combined balance sheet and unaudited condensed combined pro forma
statement of earnings of New Michael have been prepared as if the Reorganization
was consummated on March 31, 1996 and January 1, 1995 and 1996, respectively.

accompanying notes which should be read in conjunction with these pro forma
statements. These statements should be read in conjunction with the historical
financial statements of NSU, Michael, ENStar and CorVel, and the notes thereto,
which are incorporated by reference herein. The pro forma statements do not
purport to be indicative of the actual results of operations which would have
occurred had the Reorganization been consummated at the beginning of the period,
or of the future results of operations which may be obtained by ENStar or New
Michael.

                   NOTES TO THE UNAUDITED PRO FORMA CONDENSED
                         COMBINED FINANCIAL STATEMENTS
 
   
A.  To apply the cash and cash equivalents of NSU to the current maturities of
    NSU.
    
 
   
B.  To reflect the reacquisition of 2,764,633 Retired Michael Shares and the
    assumption of Net Indebtedness of $27,750,000. See "THE
    REORGANIZATION -- Effects of the Reorganization" for an example of such
    calculation. This entry also eliminates NSU's current equity in Michael and
    the related deferred income taxes.
    
 
C.  To apply fair value purchase accounting to the Net Indebtedness acquired by
    New Michael as a part of the Merger. The Net Indebtedness has an effective
    interest rate of approximately 10% and is assumed to be retired and replaced
    with indebtedness having an effective interest rate of approximately 7% six
    months after the Merger. See footnotes F and G below.
 
D.  To reclassify deferred transaction costs of Michael related to the
    Reorganization as additional cost of the Retired Michael Shares.
 
   
E.  To eliminate NSU's nonrecurring corporate general and administrative
    expenses of $249,000 and to reflect reduced compensation levels at ENStar by
    $200,000 for the year ended December 31, 1995 and by $50,000 for the quarter
    ended March 31, 1996. NSU's continuing costs are the costs of administering
    the Net Indebtedness retained by New Michael for the respective periods.
    Also to eliminate the non-recurring gain on the sale of the CorVel common
    stock.
    
 
F.  To record the amortization of the fair market value adjustment recorded by
    Michael related to the Net Indebtedness retained by New Michael. (See
    footnote C above.)
 
   
G.  To adjust interest expense related to the Net Indebtedness retained by New
    Michael assuming such indebtedness, net of the cash acquired, is retired and
    replaced with indebtedness having an effective interest rate of
    approximately 7%.
    
 
   
H.  To adjust income tax expense based on the effective income tax rate for
    Michael for the respective periods.
    
 
   
I.  To eliminate NSU's equity in earnings in unconsolidated subsidiaries.
    
 
J.  To reduce the number of shares of Michael Common Stock outstanding to
    reflect the Retired Michael Shares. The number of Retired Michael Shares was
    computed based on the calculations set forth herein under "THE
    REORGANIZATION -- Effect of the Reorganization."
 
   
K.  To reflect the pro forma income per share of ENStar utilizing the weighted
    average number of shares of NSU Common Stock outstanding for the quarter
    ended March 31, 1996 and the year ended December 31, 1995. The calculation
    assumes one share of ENStar will be distributed for every three shares of
    NSU Common Stock.

shareholder approval, to issue one or more classes or series of stock with
respect to which the New Michael Board may determine voting, conversion and
other rights which could adversely affect the rights of holders of New Michael
Common Stock. The rights of the holders of New Michael Common Stock generally
would be subject to the prior rights of any preferred stock with respect to
dividends, liquidation preferences and other matters. Among other things,
preferred stock could be issued by New Michael to raise capital or to finance
acquisitions. The issuance of preferred stock under certain circumstances could
have the effect of delaying or preventing a change of control of New Michael.
 
TRANSFER AGENT AND REGISTRAR
 
     The First National Bank of Boston is the Transfer Agent for the Michael
Common Stock and will be appointed as the transfer agent for the New Michael
Common Stock.
 
BUSINESS COMBINATION STATUTE AND CONTROL SHARE ACQUISITION ACT
 
     New Michael will be governed by the provisions of Sections 301A.671 and
302A.673 of the MBCA, which may deny shareholders the receipt of a premium for
their stock in the case of certain unfriendly acquisitions and which may also
have a depressive effect on the market price of New Michael's Common Stock. In
general, Section 302A.671 provides that the shares of a corporation acquired in
a "control share acquisition" have no voting rights unless voting rights are
approved in a prescribed manner. A "control share acquisition" is an
acquisition, directly or indirectly, of beneficial ownership of shares that
would, when added to all other shares beneficially owned by the acquiring
person, entitle the acquiring person to have voting power of 20% or more in the
election of directors. In general, Section 302A.673 prohibits a public Minnesota
corporation from engaging in a "business combination" with an "interested
shareholder" for a period of four years after the date of the transaction in
which the person became an interested shareholder, unless the business
combination is approved in a prescribed manner. "Business combination" includes
mergers, asset sales and other transactions resulting in a financial benefit to
the interested shareholder. An "interested shareholder" is a person who is the
beneficial owner, directly or indirectly, of 10% or more of the corporation's
voting stock or who is an affiliate or associate of the corporation and at any
time within four years prior to the
 
                                       65
<PAGE>   74
 
date in question was the beneficial owner, directly or indirectly, of 10% or
more of the corporation's voting stock.
 
TAKEOVER OFFERS
 
     Minnesota Statute sec. 80B.01 et seq. (the "Takeover Act") requires
registration of any takeover offer of a company which is an issuer of publicly
traded equity securities (i) which (a) has its principal place of business or
its principal executive office located in Minnesota, or (b) owns or controls
assets located in Minnesota which have a fair market value of at least
$1,000,000, and (ii) which (a) has more than ten percent of its beneficial or
record equity security holders resident in Minnesota, (b) has more than ten
percent of its equity securities owned beneficially or of record by residents in
Minnesota, or (c) has more than 1,000 beneficial or record equity security
holders resident in Minnesota. A takeover offer is an offer to acquire any
equity securities of the described companies from a resident of Minnesota
pursuant to a tender offer or request or invitation for tenders, if after the
acquisition of all securities acquired pursuant to the offer either (i) the
offeror would be directly or indirectly a beneficial owner of more than ten
percent of any class of the outstanding equity securities of the target company
and was directly or indirectly the beneficial owner of less than ten percent of
any class of the outstanding equity securities of the target company prior to
the commencement of the offer; or (ii) the beneficial ownership by the offeror
of any class of the outstanding equity securities of the target company would be
increased by more than ten percent of that class and the offeror was directly or
indirectly the beneficial owner of ten percent or more of any class of the
outstanding equity securities of the target company prior to the commencement of
the offer. A takeover offer does not include: (a) An offer in connection with
the acquisition of a security which, together with all other acquisitions by the
offeror of securities of the same class of equity securities of the issuer,
would not result in the offeror having acquired more than two percent of such
class during the preceding 12-month period; (b) an offer by the issuer to
acquire its own equity securities unless the offer is made during the pendency
of a takeover offer by a person who is not an associate or affiliate of the
issuer; or (c) an offer in which the target company is an insurance company
subject to regulation by the Minnesota Commissioner of Commerce, a financial
institution regulated by the Minnesota Commissioner of Commerce, or a public
service utility subject to regulation by the public utilities commission.
Certain limitations exist which provide that the offer must be made on
substantially the same terms inside and outside the state. The offeree has
certain rights to withdraw securities tendered and the Takeover Act provides
penalties for failure to comply with any provision of the Takeover Act of up to
$25,000 and/or up to 5 years in prison. Shares acquired in violation of the Act
are nontransferable and are denied voting rights for one year after acquisition.
New Michael can call the shares for redemption at the price that the shares were
acquired. Any seller who sells to an offeror who violates the Takeover Act can
sue, subject to the limitations period, in law or in equity, and may sue for
rescission.
 
                               BUSINESS OF ENSTAR
 
   
     ENStar was formed on December 21, 1995, as a wholly owned subsidiary of
NSU, and has had no operations and held no assets. Prior to the Effective Date,
pursuant to the terms of the Distribution Agreement, NSU will transfer all of
its assets and liabilities to ENStar, except the capital stock of Merger Co.,
all of the shares of Michael Common Stock that it holds, certain of its
outstanding indebtedness and a certain amount of cash, to be determined in the
discretion of NSU. The date of such transfer is hereinafter referred to as the
"Asset Transfer Date."
    
 
   
     At the time of the Distribution, ENStar's operations will consist of the
operations of its direct and indirect operating companies, which consist of
Americable, Inc. ("Americable") and Transition Networks, Inc. ("Transition"). In
addition, at         , 1996, NSU owned 1,225,000 shares of the common stock,
$.0001 par value, of CorVel (the "CorVel Common Stock"), which represents
approximately 27% of the outstanding shares of CorVel Common Stock . The CorVel
Common Stock is traded on the Nasdaq National Market under the Symbol CRVL. The
closing price per share of the CorVel Common Stock on         , 1996 was
$       . All of the shares of CorVel Common Stock held by NSU on the Asset
Transfer Date will be contributed to ENStar. NSU may, prior to the Asset
Transfer Date, sell from time to time some of its CorVel Common Stock pursuant
to Rule 144 of the Securities Act; however, it presently does not intend to
    
 
                                       66
<PAGE>   75
 
sell more than 50,000 shares. Proceeds from any such sale or sales would be
retained by NSU to reduce the amount of Net Indebtedness to be assumed by New
Michael in the Reorganization. ENStar contemplates that it will directly employ
seven management and administrative employees.
 
UNCONSOLIDATED SUBSIDIARY
 
     CorVel. Since its initial public offering in June 1991, CorVel has been
operated as an independent company. As a less-than-majority-owned subsidiary of
NSU, CorVel's operations have not been consolidated with NSU, and NSU's
investment in CorVel is accounted for under the equity method of accounting.
ENStar will account for its investment in CorVel in the same manner. The
following summary of CorVel's business has been prepared from information
reported by CorVel. Additional information regarding CorVel is available from
the reports and other documents prepared and filed by CorVel with the Securities
and Exchange Commission.
 
     CorVel is an independent nationwide provider of medical cost containment
and managed care services designed to address escalating medical costs. CorVel's
services include preferred provider organizations, automated medical fee
auditing, medical case management, independent medical examinations, utilization
review and vocational rehabilitation services. Such services are provided to
insurance companies, third party administrators and employers to assist them in
managing the medical costs and monitoring the quality of care associated with
medical claims.
 
     Since its initial public offering in June 1991, Jeffrey J. Michael and
Peter E. Flynn, each directors of NSU, have been members of the Board of
Directors of CorVel. Notwithstanding the sale by NSU of 350,000 shares of its
CorVel Common Stock in January 1996, and the corresponding reduction in NSU's
percentage ownership in CorVel from approximately 35% to 27%, it is expected
that Messrs. Michael and Flynn will continue to serve as members of the CorVel
Board of Directors and be nominated for re-election to the CorVel Board at the
next annual meeting of stockholders of CorVel. There are no agreements, however,
between NSU and CorVel or any of CorVel's stockholders requiring the nomination
of Messrs. Michael and Flynn or any designees of NSU for election as directors
of CorVel. NSU also does not have any agreement with CorVel requiring CorVel to
register the shares of CorVel Common Stock held by NSU. At NSU's request in
December 1995, CorVel agreed to register the 350,000 shares of CorVel Common
Stock that were sold in 1996. In the absence of registration of its CorVel
Common Stock, ENStar's ability to sell the CorVel Common Stock will be limited
to sales pursuant to Rule 144 of the Securities Act, and the volume limitations
thereof, and to private negotiated sales, which may adversely affect the ability
of ENStar to sell a large portion of its CorVel Common Stock at a given time.
 
OPERATING SUBSIDIARIES
 
GENERAL
 
     Americable. Americable was organized as a Minnesota corporation in 1981 and
was acquired by NSU in December 1986. Americable is a provider of networking and
connectivity products and services used in providing solutions for customers
operating a wide range of data communications systems. Americable has organized

PC and networking needs.
 
                                       67
<PAGE>   76
 
     As a distributor, Americable supplies a wide array of voice and data
communication related products such as cable (both copper and fiber optic),
cable assemblies, components (blocks, jacks, connectors, patch cords, patch
panels) and networking hardware. The principal focus of Americable's
distribution business, conducted primarily through its National Distribution
Sales division in Minneapolis, Minnesota, is to provide quality products, prompt
reliable delivery of such products and strong customer service both before and
after the products are sold. Americable sells to a wide range of customers
throughout the United States in the voice and data communications aftermarket,
including resellers, other distributors, systems integrators, installers and
end-users.
 
     Through Americable Custom Products, Americable manufactures a wide variety
of cable assemblies, sub-assemblies and specialty products for its customers.
While some of these products are manufactured to standard specifications for
sale by Americable through its distribution business, most are custom designed
and manufactured by Americable to customer specifications. These customer
designed products are manufactured for both end-users and original equipment
manufacturers ("OEMs").
 
     Transition. Transition develops, manufactures, markets and supports a broad
line of data networking hardware products that provide physical connectivity for
LANs and mini- and mainframe networks. Physical connectivity devices enable
computing and other electronic devices to communicate over a LAN. These devices
include high-speed switches, managed and unmanaged hubs, transceivers, media
converters and other related networking devices.
 
     Transition's products include intelligent hubs and switches, passive and
active terminal network products, including baluns, media converters and
transceivers, unmanaged Ethernet and Token Ring hubs and related host modules,
multi-port multi-media repeaters, network adapter cards and other passive
devices. Transition sells its products to a number of volume distributors and
VAR's throughout the United States and certain countries world-wide. The
customers that purchase Transition products through its network of distributors
and VAR's include system integrators, installers and end-users.
 
INDUSTRY
 
     A growing number of organizations are reengineering their businesses and
are using PC-based network technology to enhance productivity. PC networks
increase speed and flexibility, provide improved functionality to end-users and
provide greater productivity, often at lower costs. The growth in demand for
personal computers, along with recent advances in networking technology, have
led to an increase in demand for interconnected LANs and WANs. Such networks
facilitate efficient and rapid data communications among connected work groups
and departments providing for more effective utilization of information and
computing resources. As LANs have proliferated, demand for multi-vendor
interoperability has led to industry standard network protocols and access
methods such as Ethernet and Token-Ring.
 
     More recently there has been an increasing demand to connect users of LANs
in other geographic areas using WANs. Applications such as on-line services,
electronic mail, sharing of databases, multi-site product development and
transaction processing are leading the demand for the inter-networking of LANs
and WANs. The integration of LANs and WANs requires data communication products
which efficiently, reliably and quickly transmit data to appropriate locations.
 
     In the face of this rapidly changing technological environment, the
decision-making process that organizations face when planning, selecting and
implementing information technology solutions is growing more complex.
Organizations must select from numerous product options with shortening life
cycles. Although networks enhance business productivity, they typically present
complex management problems and increased administrative costs. Thus, many
organizations find it increasingly difficult and costly to maintain the internal
infrastructure needed to support their networks. As a result of these trends,
companies increasingly seek to outsource the management and support of their PC
network infrastructure.
 
     It is estimated that in 1995 the overall market in the United States for
networking products and services was approximately $50 billion.
 
                                       68

BUSINESS STRATEGY
 
     Americable. Americable's objective is to be a leading provider of a
complete range of network products and services to medium to large sized
enterprises throughout the United States. To meet this goal, Americable believes
it must seek to maintain its current customer relationships and continually
expand its customer base in the regions in which it operates, continue to
develop strong relationships with its key suppliers, look for opportunities to
expand its branch locations and develop and enhance its value-added service
offerings.
 
     During 1995, approximately 5,200 customers purchased products or services
from Americable. Management at Americable believes that preserving and enhancing
these relationships is a constant priority. Continuous quality improvement in
its operations along with expansion and enhancement of its product and service
offerings are some of the means that Americable utilizes to enhance its customer
relationships.
 
     Management at Americable also believes that developing strong relationships
with the leading manufacturers of networking products allows Americable to offer
its customers name brand products that provide the best value in meeting their
networking needs. Americable has developed relationships with leading
manufacturers within each of its principal product lines, such as Bay Networks,
Inc., AMP Incorporated and Berk-Tek Inc. and seeks to add new relationships to
expand its value-added service capabilities. Americable believes that utilizing
a select range of suppliers allows it to provide superior customer service
because its technical personnel are more familiar with the products sold and
because such high quality products are generally more reliable. Further, such
strong relationships result in greater continuity of product supply.
 
     From 1991 to 1995, Americable's domestic sales have increased from $27.6
million to $42.2 million. This increase in sales has been generated through
internal growth at Americable's four principal locations in Atlanta, Chicago,
Dallas and Minneapolis, primarily as a result of the addition of new sales,
engineering and technical personnel. Also during 1995, Americable opened smaller
satellite offices in Milwaukee, Wisconsin and Fargo, North Dakota. Americable
plans to continue its growth strategy through the addition of new sales,
engineering and technical personnel in both existing locations and new
geographic markets. Americable also intends to look for opportunities to acquire
businesses in the same or related industries in an effort to expand
geographically or enhance its value-added service offerings.
 
     Since 1989, Americable has made substantial investments in the development
of its value-added networking capabilities primarily through the addition of
engineering and technical personnel. During 1995, Americable introduced a number
of service offerings designed to provide its customers with customized
integrated solutions to meet their unique network computing needs. Revenues from
technical services and installation in 1995 represented 7% of Americable's total
revenues. Americable believes there are opportunities to increase Americable's
overall gross margins by increasing the volume of services that it currently
offers to its customers and intends to focus on increasing its service revenues.
 
     Transition. The market for Transition's products is characterized by rapid
technological change, constantly evolving industry standards and rigorous
competition with respect to timely product innovation. Because the introduction
of products embodying new technology and the emergence of new industry standards
can render existing products obsolete and unmarketable, Transition believes that
its future success will depend upon its ability to develop, manufacture and
market new products and enhancements to existing products on a cost-effective
and timely basis. Transition seeks to identify niche market opportunities for
new or enhanced products and quickly respond by offering a new or enhanced
product that may have greater capabilities, better functionability or
flexibility, greater ease of use or equivalent capabilities or functionability
but a lower price point than other competitive products.
 
     As LANs have proliferated, demand for multi-vendor interoperability has led
to industry standard network protocols and access methods such as Ethernet,
Token-Ring and Fiber Distributed Data Interface ("FDDI"). Transition has
developed the majority of its LAN products using industry standards, primarily
Ethernet. Ethernet's cabling media has evolved from coaxial cable to its
associated 10BaseTL fiber optic cabling. Management at Transition believes that
the LAN/WAN products market will continue to be driven by the migration of
end-users to new applications that demand more speed and flexibility.
Accordingly,
 
                                       69
<PAGE>   78
 
Transition's research and development efforts have been targeted at high speed
(100Mbs+) LANs and the integration of LANs and WANs into a single platform.

principal regional offices. Sales from the Americable Network Technologies
division constituted approximately 74% of Americable's net sales in 1995. In
addition to supported distribution sales, Americable Network Technologies will
oversee the design and implementation of projects involving multiple LANs across
a wide area network, consisting of multi-vendor hardware products and several
thousand nodes. Value-added projects generally range in size from $10,000 to
$500,000. During 1995, sales derived from value-added projects and services
consisted of approximately 18% of Americable's net sales. Value-added projects
and services sales include sales of products such as bulk cable, cable
assemblies and networking devices and services such as training, installation
and maintenance.
 
     The National Distribution Sales Division
 
   
     Through its distribution business, operated principally through the
National Distribution Sales division, Americable maintains a wide variety of
high-quality products in its inventory (over 5,000). Product inventory ranges
from connectivity products such as bulk cable, connectors, patch panels, racks
and other cable accessories to more complex networking electronic devices such
as concentrators, hubs, switches and routers. As a distributor, Americable
generally inventories products from multiple manufacturers. Principal
manufacturers of connectivity products include Berk-Tek, Inc., Amp Incorporated,
General Cable Corp., The Siemons Company and Leviton Manufacturing, Inc. In
addition, in an effort to reduce its inventory levels, Americable purchases a
number of networking products through large distributors such as Tech Data
Corporation, Gates/Arrow and Ingram Micro, Inc.
    
 
     Americable also maintains an integrated, real-time, on-line computerized
system for order entry, fulfillment and inventory control. This on-line computer
system allows sales personnel to advise customers over the phone of product
specifications, availability and order status. All orders are normally shipped
within 24 hours of receipt and, when necessary, can be shipped on a "same-day"
basis.
 
     The National Distribution Sales division seeks to add value for its
customers by providing superior customer service. All of Americable's sales
representatives and other sales and marketing personnel are trained to assist
customers in product selection, implementation and system upgrading and
expansion. The division's sales representatives are supported by the technical
staff of the Americable Network Technologies division, who have a broad range of
expertise in various networking technologies.
 
     The National Distribution Sales division services customers of all sizes in
the voice and data communications aftermarket. Customer orders range in size
from under $50 to several hundred thousand dollars. Average order size of the

Americable (including sales of cable assemblies) constituted approximately 26%
of Americable's net sales in 1995.
 
     Americable Custom Products
 
     As a natural extension of its distribution business, and consistent with
Americable's marketing strategy to be a single-source provider for its
customers, the Americable Custom Products division provides a manufacturing
capability to satisfy the individual needs of those customers that may require
custom or specialty cable assemblies. Americable, working to its customers'
specifications, can manufacture custom designed products such as copper,
fiber-optic, small computer system interface (SCSI) and AS/400 cable assemblies
and sub-assemblies.
 
     All Americable manufactured products are subject to strict quality control
standards to insure that they are of the same high quality as other, vendor
manufactured, distributed products. During 1996, Americable expects to complete
the process of implementing the quality standards of ISO 9002 for its
manufacturing and primary distribution operation in Minneapolis. ISO 9002 is an
international protocol for documenting processes and procedures used in
establishing a consistent manufacturing quality system.
 
                                       71
<PAGE>   80
 
     Sales from the Americable Custom Products division are generated from both
end-user and OEM customers. During 1996, Americable hopes to expand the market
for its custom and specialty cable assemblies, utilizing its in-house
manufacturing expertise of the Americable Custom Products division. For 1995,
sales to OEM customers constituted approximately 26% of total cable assembly
sales and approximately 5% of Americable's net sales.
 
     Transition. Transition's products encompass three inter-networking and
physical connectivity product families, which include (i) passive and active
terminal network products, (ii) basic LAN products and (iii) advanced LAN
products. These products encompass LAN and WAN components, which allow
Transition to offer work-group and enterprise-wide networking solutions.
 
     The terminal products family of products includes both passive and active
connectivity devices such as baluns, media converters, and transceivers that
attach personal computers to a network, thereby enabling the user to communicate
with other users in the LAN. In addition, Transition's "PowerStar" line of
active hubs provide cost-effective solutions for converting a S/3X or AS/400
Twinax daisy chain topology to an unshielded twisted pair star topology, thereby
improving network reliability and flexibility. During 1995, the terminal
products family comprised approximately 27% of Transition's net sales.
 
     Transition's basic LAN product line includes unmanaged Ethernet and Token
Ring hubs and related host modules; multi-port multi-media repeaters that
regenerate the signal, thereby allowing expansion capabilities and providing
connectivity and management of the different cabling schemes used throughout a
LAN; network adapter cards that provide direct connection from the personal
computer to a LAN; and other passive devices that provide a structured wiring
system for mini- and mainframe computer environments. Transition has developed
its Ethernet and Token Ring LAN products using industry standards. During 1995,
the basic LAN product line comprised approximately 63% of Transition's net
sales.
 
     The advanced LAN product family of Transition is a potentially high growth
product area with devices that utilize computer processors and sophisticated
internal software to manage and direct information across complex networks.
Transition's advanced LAN products are led by a multi-function hybrid
bridge/router that allows high speed switching across networks. This group of
products also includes manageable, stackable Ethernet and Token Ring hubs.
Transition believes that as network centric systems continue to grow in
sophistication, this product area will provide additional revenue opportunities.
The majority of Transition's research and development has been concentrated in
advanced LAN products with new offerings planned for 1996. During 1995, the
advanced LAN product family comprised approximately 10% of Transition's net
sales. Transition expects a significant portion of its sales growth in the
future will be derived from the introduction of new advanced LAN products.
 
MARKETING AND CUSTOMERS
 
     Americable. Americable provides its products and services to a wide range
of customers, including installers, resellers, other distributors, system
integrators, OEMs and end-users. Customer relationships are developed both
face-to-face and via the telephone.
 
     Americable's marketing strategy is two-tiered. A national effort is
centered on telemarketing through the National Distribution Sales division in
Minneapolis, Minnesota. Additionally, Americable operates each of its operating
divisions from its four principal regional offices in order to provide its
customers in each region the full array of value-added networking products and
services offered by the company.
 
     Americable has 16 outside sales representatives in addition to 43
telemarketing and sales support representatives. The sales force is supplemented
by 22 regional technical service engineers and technicians and two corporate
product managers. Americable sales representatives undergo continuous training
and attend company-sponsored classes in order to enhance their technical
expertise and marketing techniques. Also, many of Americable's sales and
technical personnel attend vendor-sponsored training and education programs
mandated by such vendors in order for Americable to qualify as a licensed
reseller of their products.
 
     Americable also uses direct mailings, brochures and catalogs in marketing
the products that it distributes. Americable's catalog, which generally is
published every 18 months, is designed to provide end-users with not
 
                                       72
<PAGE>   81
 
   
only product specifications, but additional technical information to assist them
in connection with their system design. Americable's latest catalog was released
in April 1996.
    
 
   
     During 1995 and the first quarter of 1996, Americable had one customer that
constituted approximately 11% and 17%, respectively, of net sales and a
different customer accounted for approximately 9% and 15%, respectively, of net
sales. In addition, in 1995 and the first quarter of 1996, Americable derived
approximately 61% and 70%, respectively, of its sales from its largest 100
customers.
    
 
   
     Transition. Transition distributes its products through a number of volume
distributors and VARs throughout the United States and in over 50 countries
worldwide. Distributors and VARs purchase Transition's products at standard
discounts based on certain volume-based incentive programs. Transition's
international sales have accounted for a substantial portion of its sales
growth, coming primarily from the United Kingdom, South Africa, Australia and
Sweden. During 1995 and the first quarter of 1996, revenues from outside the
United States accounted for approximately 37% and 38%, respectively, of net
sales.
    
 
     Transition's continued growth will be dependent, in part, upon its ability
to expand its domestic and international distributor base with high quality
VARs. A significant benefit for a distributor or VAR is that Transition does not
sell directly to end users. Transition's distributors and VARs carry other
products that are complementary to, and compete with those of Transition, and
these non-exclusive distributors and VARs may choose to give higher priority to
products of other suppliers or competitors.
 
     Transition has several marketing programs to support the sale and
distribution of its products. Its marketing programs are designed to generate
sales leads for its distribution channels, as well as to enhance brandname
recognition. Transition's marketing activities include frequent participation in
industry trade shows, advertising in major trade publications, public relations
campaigns, the distribution of sales literature and product specifications, and
ongoing communications with its distributors. In addition, Transition offers
comprehensive pre- and post-sales technical support, distributor/VAR product
training, and a strategic test partner program. Transition utilizes reseller
incentive programs such as co-op funds to increase localized print advertising
and name recognition. The marketing budget has been increased for both 1995 and
1996 to enhance Transition's image and name recognition.
 
RESEARCH AND DEVELOPMENT
 
     Transition. Transition performs all of its research and development
activities at its headquarters in Eden Prairie, Minnesota. Transition believes
that its future success depends on its ability to achieve market acceptance of
new product offerings, especially in the advanced LAN products area. The
engineering staff has increased by 36% since the end of 1994, to accelerate
development in this area. Although there can be no assurance that its
development efforts will result in commercially successful products, Transition
intends to continue to make substantial investments in the development of new
and enhanced products. During 1995, research and development expenses totaled
approximately $1,440,000, or approximately 10% of net sales.
 
MANUFACTURING
 
     Americable. Americable's manufacturing operations consist of the
manufacture of custom or specialty cable assemblies including copper,
fiber-optic, small computer system interface (SCSI) and AS/400 cable assemblies
and sub-assemblies through its Americable Custom Products division.
 
     Transition. Transition's manufacturing operations consist primarily of the
final assembly and quality control testing of materials, components and
subassemblies. Transition uses third parties to perform printed circuit board
assembly. Transition's products include certain components that are currently
available from single or limited sources and may require long order lead times.
Any reduction in supply or substantial change in costs of components could
affect Transition's ability to deliver its products in a timely and
cost-effective manner and may adversely impact Transition's operating results.

COMPETITION
 
     Americable. Americable faces substantial competition within each of its
business segments from a large number of companies, some of which are larger,
have greater financial resources, broader name recognition and, in many cases,
lower product and operating costs than Americable. The Americable Network
Technologies division faces competition from large system integrators such as
AmeriData Technologies, Inc., Vanstar Corporation and a significant number of
smaller regional VAR's and system integrators. Significant competitors in the
National Distribution Sales division's business include Anixter Bros., Inc., a
subsidiary of Anixter International, Inc, and Graybar Electric Co., Inc. The
products of the Americable Custom Products division are not protected from
competition by virtue of any proprietary rights such as trade secrets or
patents. Americable Custom Products encounters competition from domestic
companies such as Kent Electronics Corporation and a number of smaller domestic
companies, in addition to a number of products manufactured outside the United
States.
 
     Transition. The industry in which Transition operates is highly
competitive, and Transition believes that such competition will continue to
intensify. The industry is characterized by rapid technological change, short
product life-cycles, frequent product introductions and evolving industry
standards. Transition competes with a number of independent companies focused on
designing and manufacturing products for the LAN market, including, among
others, 3Com, Bay Networks, Cabletron System, Inc., Allied Telesis, Inc., and
Digi International. Most of Transition's competitors are established companies
with significantly greater financial resources, more extensive business
experience, and greater market and service capabilities than Transition. There
can be no assurance that Transition will be able to compete successfully.
 
     Transition's ability to compete successfully depends upon its ability to
adapt to market changes on a timely basis. There are many networking products
currently being offered in the market segments in which Transition competes.
Transition believes that customers evaluate competing products on the basis of
required product features for a particular installation, performance, price and
ease of use. In addition, after installation, customers evaluate the suppliers'
ability to provide readily accessible on-site/remote technical support, if
required, and its reliability when deciding on future orders for additional
equipment. Failure to obtain significant customer satisfaction or market share
could have a material adverse effect on Transition.
 
PROPERTIES
 
     Americable. Americable's headquarters are located in a 20,000 square foot
facility in Itasca, Illinois, a suburb of Chicago. Americable's principal
distribution and manufacturing operations are located in Minneapolis, Minnesota
(39,000 square feet). This facility includes office, warehouse and production
space. Americable also has branch operations in Dallas, Texas (15,000 square
feet), and Atlanta, Georgia (9,900 square feet) in addition to satellite offices
in Milwaukee, Wisconsin and Fargo, North Dakota. All of Americable's facilities
are leased.
 
     Transition. Transition's headquarters, including its executive and
corporate administration offices, manufacturing, sales and technical support are
located in Eden Prairie, Minnesota, which consists of approximately 20,500
square feet of leased space.
 
LEGAL PROCEEDINGS
 
   
     Americable and Transition are engaged in routine litigation incidental to
their respective businesses, which management believes will not have a material
adverse effect upon the business or consolidated financial position of either
company.

         MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS
                       AND FINANCIAL CONDITION OF ENSTAR
 
GENERAL
 
   
     ENStar is currently an operating unit of NSU. ENStar is comprised of
Americable and Transition along with an equity investment in CorVel and certain
other assets. At March 31, 1996, NSU owned a 27% ownership interest in CorVel
following the sale of 350,000 shares in January 1996. The financial statements
of ENStar reflect the investment in CorVel assuming ENStar owned a 27% ownership
interest for all periods presented. ENStar's investment in CorVel is accounted
for as an unconsolidated subsidiary using the equity method of accounting. The
common stock of CorVel is included on the NASDAQ National Market System under
the symbol CRVL.
    
 
     As described in Note 2 to the Combined Financial Statements of ENStar, the
Combined Statements of Income of ENStar include an allocation of general and
administrative costs incurred by NSU in the management of the operating
companies, investment holding and other assets of ENStar. Management believes
these allocations are reasonable and present the operations of ENStar as though
it was operated on a stand alone basis.
 
   
     The following are summarized operating results for each of ENStar's
operations for the three months ended March 31, 1995 and March 31, 1996 and each
of the three years ended December 31, 1995 (in thousands):

RESULTS OF OPERATIONS
 
   
THREE MONTHS ENDED MARCH 31, 1996 VERSUS THREE MONTHS ENDED MARCH 31, 1995
    
 
   
     Combined revenues increased $2.8 million or 22.3%, to $15.4 million from
$12.6 million in 1995.
    
 
   
     Revenues at Americable increased approximately $2.8 million, or 30.4%, to
$12.1 million. This includes increased sales of networking products of
approximately $3.3 million and approximately $300,000 of increased revenues from
installation and services, both due primarily to higher demand. Included in
these amounts is approximately $2.6 million of increased sales of networking
products from two customers, which increase in volume is not expected to
continue for the remainder of the year. Offsetting these increases was
approximately $390,000 of decreased sales of cable assemblies due primarily to
reduced pricing within modular assembly applications because of technological
changes. In addition, sales of cable and other connectivity products decreased
approximately $370,000 due primarily to lower mix of volume to contractors and
resellers and lower demand experienced for certain types of bulk cable due to
increased market supply during the period.
    
 
   
     As a result of increased competition and ongoing pricing pressures,
revenues at Transition were relatively unchanged between years. Sales of
Transition's advanced LAN products increased approximately 48% to $427,000,
reflecting additional revenues from new products introduced during 1995. Sales
from new product introductions and enhancements accounted for approximately 2%
of net sales for the quarter ended March 31, 1996 versus $870,000 or 24% for the
comparable period in 1995. Sales of basic LAN and terminal products decreased
approximately 4% to $3.2 million. Sales to domestic customers decreased
approximately $24,000 or 1%, to $2.2 million which primarily reflects a lower
volume of new product introductions sold during the period. Sales to
international customers increased approximately $33,000 or 2%, to $1.4 million
which was primarily a result of the addition of new customers.
    
 
   
     Combined gross profit, as a percent of revenues, decreased to 27.1% in 1996
as compared to 30.1% in 1995. Decreased margins at Americable are primarily
attributable to a higher volume of lower margin networking products and lower
pricing on cable due to competition and overall higher market supply on certain
types of bulk cable. The increased margins at Transition were primarily a result
of product mix between periods, and are not expected to continue at such levels.
ENStar expects its gross profit margins to decline due to expected competitive
pricing pressures on products sold by both Americable and Transition.
    
 
   
     ENStar's selling, general and administrative expenses increased $429,000 or
12.4%, to $3.9 million from $3.5 million in 1995. Operating expenses at
Americable increased approximately $248,000 or 11% for the period which reflects
approximately $170,000 of increased selling expenses primarily attributable to
higher sales commissions and the addition of new sales personnel and related
expenses. In addition, this increase reflects approximately $80,000 of higher
engineering expense due to the addition of technical and engineering personnel.
Americable expects that its selling expenses, as a percentage of revenues, may
increase during the remainder of 1996 through the addition of sales and
technical personnel in new geographic locations in addition to costs associated
with a new catalog which was released in April 1996. These anticipated increases
in operating expenses may result in lower operating profits at Americable if the
company is unable to maintain current gross profit margins and continued sales
growth.
    
 
   
     Transition had increased operating expenses of approximately $215,000 or
21%, which reflects increased engineering expenses of approximately $123,000 due
to the addition of engineering personnel associated with new product
development. In addition, selling expenses increased approximately $73,000 due
primarily to higher promotional expenses. In an effort to successfully develop
and launch new advance LAN products, Transition anticipates the increased levels
of spending on engineering, marketing and promotional costs to continue
throughout 1996. If such increased level of spending does not result in the
timely introduction of commercially successful products, Transition may
experience significantly reduced levels of sales growth and operating results
during the remainder of 1996.
    
 
   
     Net interest expense decreased $17,000 or 20% to $66,000 from $83,000 in
1995 due primarily to lower outstanding borrowing levels under Americable's
revolving credit facility and lower interest rates between years.

     The income tax provision in 1996 and 1995 reflect ENStar's estimated
effective annual tax rate. See Note 7 to the Combined Financial Statements of
ENStar.
    
 
   
     Equity in earnings of unconsolidated subsidiary increased $21,000 to
$304,000 from $283,000 in 1995, which is a result of higher earnings at CorVel.
Further information with respect to the results of operations of CorVel is
contained in the Management's Discussion and Analysis of Financial Condition and
Results of Operations section of its report on Form 10-K for the year ended
March 31, 1996, as filed with the Securities and Exchange Commission.
    
 
   
1995 VERSUS 1994
    
 
     Revenues at Americable increased approximately $5.2 million, or 14.1%, to
$42.1 million. This includes increased revenues of $4.5 million resulting from
higher demand for networking products. Of this amount, approximately $3.1
million of sales were attributable to higher volume of networking products with
a large end user customer which is not expected to continue during 1996. The
increase in revenue of Americable also includes approximately $650,000 of higher
volume of service revenues due to increased focus on services and the addition
of technical personnel. In addition, sales of cable assemblies increased by
approximately $100,000 primarily a result of higher demand of OEM assemblies
offset by reduced pricing within modular assembly applications due to
technological changes.
 
     Revenues at Transition increased approximately $2.5 million, or 21% which
includes increased sales of approximately $1.1 million, or 25%, to international
customers and approximately $1.4 million, or 19% higher sales to domestic
customers. Sales to international customers consisted of 37% and 35% of
Transition's revenues in 1995 and 1994, respectively. This growth was due to
increased unit sales of its terminal products and both its basic and advanced
LAN product groups. Overall, these increases are primarily a result of new
product introductions during the end of 1994 and throughout 1995. During 1995,
new product introductions and enhancements accounted for $1.1 million, or 9% of
net sales. Transition's ability to maintain its present level of sales and its
continued sales growth is highly dependent upon its ability to offer new
products that meet customer's demands in a rapidly changing market, particularly
in light of the relatively short life cycle of its products.
 
     Combined gross profit, as a percentage of revenues, increased to 28% in
1995 as compared to 27.3% in 1994. Increased margins at Americable are primarily
attributable to a higher mix of value-added service revenue and, to a lesser
extent, improved pricing and improved manufacturing efficiencies within its
cable assembly operations. Decreased margins at Transition were a result of
lower pricing on certain product lines due to increased competition. For 1996,
ENStar expects its gross profit margins to decline due to expected competitive
pricing pressures on products sold by both Americable and Transition.
 
     ENStar's selling, general and administrative expenses increased $766,000,
or 5.6% to $14.3 million from $13.6 million in 1994. Operating expenses at
Americable increased approximately $600,000, or 7% which reflects higher selling
expenses of approximately $700,000 which is primarily a result of higher sales
commissions and the addition of technical and engineering personnel, along with
additional expense for amounts earned under its incentive compensation program
of approximately $200,000. These increases were offset by the impact of
approximately $300,000 of annualized savings realized through reorganizations
effected within its U.S. operations in the third quarter of 1994 and the first
quarter of 1995. Americable expects that its selling expenses, as a percentage
of revenues, may increase during 1996 through the addition of sales and
technical personnel in new geographic locations in addition to costs associated
with a new catalog expected for release in the first quarter of 1996. These
anticipated increases in operating expenses may result in lower operating
profits at Americable, if the company is unable to maintain current gross profit
margins and continued sales growth.
 
     Transition increased operating expenses approximately $213,000 or 5%. This
includes approximately $125,000 of increased sales and marketing expenses due to
higher promotional and advertising expenses associated with new product
introductions and the company's name change, and approximately $220,000 of
increased engineering expenses associated with the additional personnel to
support new product development. In addition, this increase reflects higher
expenses of approximately $175,000 related to moving to a new
 
                                       77
<PAGE>   86
 
facility and the addition of administrative personnel and related facility
expenses needed to support its overall growth. These increases were offset by a
decrease in engineering expenses of approximately $300,000 due to lower spending
on parts, equipment, and other costs related to hardware development projects.
This reflects a shift towards higher software development associated with its
advanced LAN products. Transition expects that its research and development
expenses will increase in 1996 based on the planned addition of engineering
personnel for new product development. There can be no assurances, however, that
its research and development efforts will result in commercially successful new
products in the future. In addition, Transition believes that sales and
marketing expenses may continue to increase in terms of absolute dollars in an
effort to differentiate its products and enhance its competitive position. These
anticipated increases in operating expenses are expected to result in lower
operating profit at Transition, particularly if the company is unable to
maintain its current gross profit margins and continued sales growth.
 
     Net interest expense decreased by approximately $100,000 due primarily to
lower outstanding borrowings under Americable's revolving credit facility.
 
     ENStar's effective combined income tax rate was 51.5% in 1995 and (32.4%)
in 1994. See Note 7 to the Combined Financial Statements of ENStar.
 
     Equity in earnings of unconsolidated subsidiary increased $195,000 to
approximately $1.2 million in 1995 from approximately $1 million in 1994, which
is a result of higher earnings at CorVel. CorVel's net earnings for the twelve
months ended December 31, 1995 were approximately $7 million, an increase of
approximately $1.5 million or 27% from the previous year.
 
1994 VERSUS 1993
 
     Revenues at Americable, excluding approximately $4.6 million of revenue in
1993 from its Canadian operations, which were closed in December 1993, increased
$3.3 million, or 9.8%, to $36.9 million. This includes increased revenues of $5
million resulting from higher demand for value-added networking products and
services offset by decreased sales of bulk cable and other connectivity products
of $1.2 million due primarily to lower volume of sales to contractors and
resellers. In addition, sales of cable assemblies decreased by approximately
$500,000 as a result of reduced pricing within modular assembly applications due
to technological changes.
 
     Revenues at Transition increased approximately $1.8 million, or 18% which
includes increased sales of approximately $1.1 million, or 33%, to international
customers and approximately $700,000, or 10% higher sales to domestic customers.
Sales to international customers consisted of 35% and 31% of Transition's
revenues in 1994 and 1993, respectively. Overall, these increases are primarily
a result of new product introductions during the end of 1993 and throughout
1994. During 1994, new product introductions and enhancements accounted for $3.3
million, or 28% of net sales.
 
     Combined gross profit, as a percentage of revenues, decreased to 27.3% in
1994 as compared to 30.3% in 1993. Margins at Americable decreased due to
overall lower pricing resulting from increased competition. Margins at
Transition were unchanged in 1994 from 1993.
 
     ENStar's selling, general and administrative expenses, excluding
restructuring charges, decreased $615,000, or 4.3% to $13.6 million from $14.2
million in 1993. Operating expenses at Americable decreased approximately $1.9
million, which reflects approximately $1.2 million of expenses eliminated
through the closure of its Canadian facilities effected in December 1993, and
$700,000 of other savings realized through a reorganization effected within its
U.S. operations in the third quarter. These decreases were offset by increased
expenses of $1.3 million at Transition due to the addition of sales and
engineering personnel and increased research and development expenses related to
new product introductions and additional administrative and support personnel
needed to support overall growth.
 
     Net interest expense was relatively unchanged between 1994 and 1993.
 
     ENStar's effective combined income tax benefit rate was 32.4% in 1994 and
3.0% in 1993. See Note 7 to the Combined Financial Statements.
 
                                       78
<PAGE>   87
 
     Equity in earnings of unconsolidated subsidiary increased $251,000 to
approximately $1 million in 1994 from $745,000 in 1993 which is a result of
higher earnings at CorVel. CorVel's net earnings for 1994 were approximately
$5.5 million, an increase of approximately $1.7 million or 43% from the previous
year.
 
CAPITAL RESOURCES AND LIQUIDITY
 
   
     Historically, ENStar has experienced cash flow deficits from operations and
has experienced fluctuations in its working capital which are primarily
attributable to the increase in receivables and inventories associated with
growth in sales and timing of payments on accounts payable.
    
 
   
     ENStar used cash in operations of approximately $1.1 million in 1994 versus
net cash provided from operations of approximately $1.5 million in 1995. Cash
used in operations was $508,000 for the three months ended March 31, 1996,
versus net cash provided from operations of $735,000 in 1995. The increases in
cash from operations is primarily a result of higher operating profits at
Americable and Transition. Historically, ENStar has experienced fluctuations in
its working capital which is primarily attributable to the increase receivables
and inventories associated with growth in sales and timing of payments on
accounts payable. For 1995 and 1994 cash provided by investing activities
primarily represents collections on notes receivable offset by capital
expenditures.
    
 
     Since CorVel's initial public offering in July 1991, ENStar has not had the
use of cash generated by CorVel and its subsidiaries. Also, since its initial
public offering, CorVel has not declared any dividends and has indicated that it
does not anticipate doing so for the foreseeable future. ENStar may from time to
time, depending on market conditions and other factors, sell a portion of its
CorVel holdings.
 
   
     Americable and Transition maintain a revolving line of credit and term loan
facility which provides borrowings up to $5.5 million due in May 1996, which was
extended to June 30, 1996. Borrowings under the revolving credit facility are
based on eligible accounts receivable and inventory with interest at prime plus
1.5%, (9.75% at March 31, 1996). At March 31, 1996, there were outstanding
borrowings of $1.2 million under the revolving credit facility and $964,000
under the term note. Management is currently in the process of negotiating terms
of a new credit facility and expects to obtain available borrowing levels and
terms that are comparable with its existing facility.
    
 
     Upon completion of the Reorganization, ENStar intends to initiate a
program, similar to that historically maintained by NSU, whereby it will sell
subordinated debentures of various maturities to primarily individual investors.
The debentures are intended to be offered on a continuous basis at interest
rates that change from time to time depending on market conditions. Proceeds
from this program are intended to fund the growth of ENStar's operating
companies along with potential acquisitions and general corporate purposes.
There can be no assurance, however, that ENStar will implement this program or
that any attempted implementation of such a program would be successful.
 
     ENStar expects to be able to fund its working capital and capital
expenditure requirements for 1996 with cash flow from operations along with the
amounts available under the credit facilities of its operating companies. During
1996, ENStar's operating plans call for approximately $1 million in capital
expenditures.
 
                    COMPARISON OF RIGHTS OF NSU SHAREHOLDERS
                      BEFORE AND AFTER THE REORGANIZATION
 
     If the Reorganization is consummated, then after the Effective Time shares
of Common Stock of NSU will be exchanged for shares of Common Stock of New
Michael and ENStar. Like NSU and New Michael, ENStar is a Minnesota corporation
governed by Minnesota law, its Articles of Incorporation and its Bylaws.
Pursuant to the Reorganization, the existing Amended and Restated Bylaws of NSU
will become the Bylaws of New Michael. Such Amended and Restated Bylaws are
substantially the same as the Bylaws of ENStar. The existing Restated Articles
of Incorporation of NSU are referred to herein as the "NSU Articles." A copy of
the Amended and Restated Articles of Incorporation of NSU that will be adopted
if approved by the shareholders of NSU at the NSU Annual Meeting is included as
Exhibit D to Appendix I hereto. See "PROPOSAL NUMBER FOUR: PROPOSAL TO ADOPT AN
AMENDMENT TO THE RESTATED
 
                                       79
<PAGE>   88
 
ARTICLES OF INCORPORATION OF NSU." Such Restated Articles of Incorporation are
referred to herein as the "New Articles." The Restated Articles of Incorporation
of ENStar are referred to herein as the "ENStar Articles." There are certain
differences between the NSU Articles, the New Articles and the ENStar Articles.
The following is a summary of some of the significant differences.
 
     The NSU Articles provide for authorized Capital Stock of 100,035,000
shares, comprised of 100,000,000 shares of Common Stock with a par value of $.25
per share and 35,000 shares of preferred stock with a par value of $100 per
share. The New Articles will provide for authorized Capital Stock of 50,000,000
shares, comprised of 40,000,000 shares of common stock with a par value of $.01
per share and 10,000,000 undesignated shares. The New Articles will eliminate
the existing designation of the rights and preferences of NSU Common Stock and
NSU Preferred Stock. The Board of Directors will be able to establish by
resolution different classes or series of shares and to fix the rights and
preferences of any New Michael Preferred Stock to be issued. The rights and
preferences of New Michael Common Stock will be as provided under Minnesota law.
The ENStar Articles provide for authorized capital stock of 100,000,000,
comprised of 80,000,000 shares of Common Stock with a par value of $.01 per
share and 20,000,000 shares of Preferred Stock with a par value of $.01 per
share. All shares of ENStar Common Stock are voting shares and are entitled to
one vote per share. The board of directors has the authority to fix the rights
and preferences of preferred shares.
 
     The NSU Articles mandate that the Board of Directors consist of at least
one but not more than 15 directors. The New Articles will set the minimum number
of directors at three but will not fix a maximum number. It will also permit the
board, in its discretion, to elect honorary, non-voting directors. The ENStar
Articles fix the initial number of directors at five. Thereafter, the number of
directors may be fixed by the board or by the affirmative vote of voting power
of outstanding ENStar Common Stock.
 
     Under the NSU Articles, directors may take written action in lieu of action
at a meeting unless the matter requires shareholder approval. The number of
directors required to approve a written action is an absolute majority. Under
the New Articles, a written action on a matter requiring shareholder approval
must be signed by all directors. Written action on other matters may be taken by
an absolute majority of directors. The ENStar Articles are identical to the New
Articles in this respect.
 
     The NSU Articles do not explicitly require indemnification of directors,
officers or employees. The New Articles require NSU to indemnify any person who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding, including an action by or in the right
of NSU to the fullest extent permitted under the Minnesota Business Corporation
Act. The ENStar Articles also require such indemnification.

     Mr. Thomas Wargolet joined NSU in September 1989 and has been its
Controller since that time. Mr. Wargolet was also the Director of Finance of
Americable from September 1991 until January 1995. Since January 1995, Mr.
Wargolet has been the Vice President of Finance and Operations of Americable.
Prior to joining NSU in 1989, Mr. Wargolet was an Audit Senior with Arthur
Andersen & Co.
 
     Mr. Gary Eizenga joined Americable in September 1989 as Chief Operating
Officer and held that position until January 1991, at which time Mr. Eizenga
became President and Chief Executive Officer of Americable. Prior to joining
Americable, Mr. Eizenga held various positions with American Hospital Supply, a
division of Baxter International.
 
     Mr. Gary Doan founded Transition in 1987 and was its President until
December 1992, at which time he became Chairman and Chief Executive Officer.
 
     Officers of ENStar will be elected annually by the Board of Directors.
 
COMPENSATION OF EXECUTIVE OFFICERS OF ENSTAR
 
     ENStar will rely on the Compensation Committee of the Board of Directors
(composed of non-employee members) to recommend the form and amount of
compensation to be paid to ENStar executive officers.
 
     At the Compensation Committee meeting held on March 5, 1996, base annual
salaries for Messrs. Jeffrey J. Michael, Flynn and Wargolet of $175,000,
$150,000 and $90,000, respectively, were established by the Compensation
Committee and approved by the ENStar Board of Directors, subject to consummation
of the Reorganization. The Compensation Committee also discussed a proposed
bonus program that would provide for the payment of certain cash bonuses to the
ENStar officers based on ENStar's financial performance. Similar to the cash
bonus arrangements that NSU has established from time to time in the past, cash
bonuses for officers of ENStar would be earned based on a structured formula.
Performance targets would be established based on budgeted annual operating
results and cash bonuses would be calculated as a percentage of such officers'
base salary depending on actual financial performance compared to the
performance targets. It is anticipated that such bonuses will range from 0% to
75% of the officers' base salaries, depending upon the officer's position with
the Company. The establishment of the bonus program, the performance targets
relating thereto and the percentage of an officer's salary subject to such bonus
will be determined subsequent to the consummation of the Reorganization.
 
     Messrs. Doan and Eizenga will continue to receive the same base
compensation and participate in the incentive compensation programs at each of
Transition and Americable, respectively. Mr. Doan was paid a base salary of
$120,000 in 1995, and received a bonus of $24,000, based on Transition's 1995
financial performance. Mr. Eizenga was paid a base salary of $162,500 in 1995,
and received a bonus of $65,000, based on Americable's 1995 financial
performance.
 
     The Compensation Committee also approved the granting of non-qualified
stock options under the ENStar 1996 Stock Incentive Plan to each of Messrs.
Jeffrey J. Michael, Flynn and Wargolet at its March 5, 1996 meeting. Such
options provide for the purchase of 28,500, 23,500 and 14,250 shares of ENStar
Common Stock, respectively, at an exercise price per share of $9.00. The options
granted to Messrs. Jeffrey J. Michael, Flynn and Wargolet vest 25% per year over
four years and have a term of ten years. Such options terminate automatically if
the Reorganization is not consummated prior to the first anniversary of the date
of grant. The Compensation Committee currently does not plan to issue stock
options to Messrs. Doan and Eizenga.
 
     The Compensation Committee intends to generally adhere to compensation
policies that reflect the belief that ENStar must attract and retain individuals
of outstanding ability and motivate and reward such individuals for sustained
performance. The Committee also believes the ENStar levels of compensation
should generally be in line with what the executive officers of ENStar were
offered in their capacities as executive officers of NSU. On an ongoing basis,
the type and amount of compensation to be paid by ENStar to its officers will be
entirely discretionary and within the subjective judgment of the Compensation
Committee. It is currently anticipated that none of the officers of ENStar,
other than Messrs. Doan and Eizenga, will have employment agreements with
ENStar.

of NSU for the 1995 fiscal year, see "ELECTION OF NSU DIRECTORS."
 
COMPENSATION OF DIRECTORS OF ENSTAR
 
     Directors who are not officers or employees of ENStar will receive an
annual retainer of $8,000. Such directors will also receive $300 per meeting for
each meeting of a committee of the Board of Directors that they attend.
Directors incurring travel expenses to attend meetings are reimbursed in full.
ENStar non-employee directors will also be eligible to receive certain stock
options pursuant to the ENStar 1996 Stock Incentive Plan discussed below.
 
COMMITTEES OF THE BOARD OF ENSTAR
 
     Audit Committee. ENStar has established a standing Audit Committee, which
consists of Mr. Efron and Mr. Braun with Mr. Braun serving as Chairman. The
Audit Committee will review and make recommendations and reports to the Board
with respect to (i) the independent auditors, (ii) the quality and effectiveness
of internal controls, (iii) engagement or discharge of the independent auditors,
(iv) professional services provided by the independent auditors, and (v) the
review and approval of major changes in NSU's accounting principals and
practices.
 
     Compensation Committee. ENStar has a standing Compensation Committee which
consists of Mr. Efron as Chairman and Mr. Braun. The Compensation Committee will
consider and recommend to the Board salary schedules and other remuneration for
ENStar's executive officers. This committee will also administer the ENStar 1996
Stock Incentive Plan.
 
1996 STOCK INCENTIVE PLAN
 
     On March 5, 1996, the Board of Directors of ENStar approved and adopted,
and NSU, as sole shareholder of ENStar, approved the ENStar 1996 Stock Incentive
Plan (the "Plan"). The following discussion of the Plan is qualified by
reference to the full text of the Plan which is available upon request to the
Secretary of ENStar.
 
     The purpose of the Plan is to promote the interests of ENStar and its
shareholders by aiding ENStar in attracting and retaining management personnel
capable of assuring the future success of, and non-employee directors capable of
providing strategic direction to ENStar, to offer such personnel and directors
incentives to put forth maximum efforts for the success of ENStar's business, to
afford such personnel and directors an opportunity to acquire a proprietary
interest in ENStar and to align further the interests of such personnel and
directors with ENStar's shareholders.
 
     Administration. With the exception of the provisions applicable to
non-employee directors, which are discussed below, the Plan will be administered
by the Compensation Committee of the Board of Directors of ENStar (the
"Committee"). The Committee has the authority to select the individuals to whom
awards are granted, to determine the types of awards to be granted and the
number of shares of ENStar Common Stock covered by such awards, to set the terms
and conditions of such awards, and to determine whether the payment of any
amounts received under any award shall or may be deferred. The Committee has the
authority to establish rules for the administration of the Plan, and
determinations and interpretations with respect to the Plan are at the sole
discretion of the Committee, whose determinations and interpretations are
binding on all interested parties. The Committee may delegate its powers and
duties under the Plan to one or more officers with respect to persons who are
not subject to Section 16 of the Exchange Act but it may not delegate any of its
powers and duties under the Plan in such a manner as would fail to comply with
any of the requirements of Section 162(m) of the Code.
 
     Terms of the Plan. The Plan permits the granting of a variety of different
types of awards: (i) stock options, including incentive stock options meeting
the requirements of Section 422 of the Code, and stock options that do not meet
such requirements (non-qualified stock options); (ii) stock appreciation rights
(SARs); (iii) restricted stock and restricted stock units; (iv) performance
awards; (v) dividend equivalents;
 
                                       82
<PAGE>   91
 
and (vi) other awards valued in whole or in part by reference to or otherwise
based upon ENStar Common Stock ("other stock-based awards"). Awards may be
granted alone, in addition to, in tandem with, or in substitution for any other
award granted under the Plan or any other plan. Awards may be granted for no
cash consideration or for such minimal cash consideration as may be required by
applicable law. Awards may provide that upon the grant or exercise thereof the
holder will receive cash, shares of ENStar Common Stock or other securities,
awards or property, or any combination thereof, as the Committee shall
determine. The exercise price per share under any stock option, the grant price
of any SAR, and the purchase price of any security which may be purchased under
any other stock-based award under Section 6(f) of the Plan may not be less than
100 percent of the fair market value of ENStar Common Stock on the date of the
grant of such option, SAR or right. Determinations of fair market value under
the Plan are made in accordance with methods and procedures established by the
Committee.
 
     Options may be exercised by payment in full of the exercise price, either
in cash or, at the discretion of the Committee, in whole or in part by the
tendering of shares of ENStar Common Stock or other consideration having a fair
market value on the date the option is exercised equal to the exercise price.
The Plan provides that the Committee may grant "reload options," separately or
together with another option, and may establish the terms and conditions of such
reload options. Pursuant to a reload option, the optionee would be granted a new
option when the payment of the exercise price of the option to which such reload
option relates is made by using shares of ENStar Common Stock owned by the
optionee. The new option granted upon such exercise would be an option to
purchase the number of shares not exceeding the sum of (i) the number of shares
of ENStar Common Stock tendered as payment upon the exercise of the option to
which such reload option relates and (ii) the number of shares of ENStar Common
Stock tendered or withheld as payment of the amount to be withheld under
applicable tax laws in connection with the exercise of the option to which such
reload option relates. Reload options may be granted with respect to options
previously granted under the Plan or any other stock option plan of ENStar, and
may be granted in connection with any option granted under the Plan or any other
such plan at the time of such grant. Such reload options shall have a per share
exercise price equal to the fair market value as of the date of grant of the new
option. Any such reload option shall be subject to availability of sufficient
shares for grant under the Plan. Shares surrendered as part or all of the
exercise price of the option to which it relates that have been owned by the
optionee less than six months will not be counted for purposes of determining
the number of shares that may be purchased pursuant to a reload option.
 
     The holder of an SAR is entitled to receive the excess of the fair market
value (calculated as of the exercise date or, if the Committee shall so
determine, as of anytime during a specified period before or after the exercise
date) of a specified number of shares over the grant price of the SAR.
 
     Shares of restricted stock and restricted stock units will be subject to
such restrictions as the Committee may impose (including any limitations on the
right to vote or the right to receive dividends), which restrictions may lapse
separately or in combination at such time or times, in such installments or
otherwise as the Committee may determine. Restricted stock may not be
transferred by the holder until the restrictions established by the Committee
lapse. Holders of restricted stock units have the right, subject to any
restrictions imposed by the Committee, to receive shares of ENStar Common Stock
at some future date. Upon termination of the holder's employment during the
restriction period, restricted stock and restricted stock units are forfeited,
unless the Committee determines otherwise.
 
     Performance awards provide the holder thereof the right to receive
payments, in whole or in part, upon the achievement of such goals during such
performance periods as the Committee shall establish. A performance award
granted under the Plan may be denominated or payable in cash, shares of ENStar
Common Stock or restricted stock or restricted stock units, or other securities,
awards or property. Dividend equivalents entitle the holder thereof to receive
payments (in cash, shares or otherwise, as determined by the Committee)
equivalent to the amount of cash dividends with respect to a specified number of
shares. The Committee is also authorized to establish the terms and conditions
of other stock-based awards.
 
     Restrictions on Awards and Transfers. No person who is an employee of
ENStar at the time of grant may be granted any award or awards under the Plan,
the value of which awards are based solely on an increase
 
                                       83
<PAGE>   92
 
in the value of the shares after the date of grant of such awards, of more than
170,000 shares, in the aggregate, in any calendar year. The foregoing annual
limitation specifically includes the grant of any awards representing "qualified
performance-based compensation" within the meaning of Section 162(m) of the
Code.
 
     No award granted under the Plan may be assigned, transferred, pledged or
otherwise encumbered by the individual to whom it is granted, otherwise than by
will or the laws of descent and distribution, except that the Committee may
permit the designation of a beneficiary. Each award is exercisable, during such
individual's lifetime, only by such individual or, if permissible under
applicable law, by such individual's guardian or legal representative.
 
     The aggregate number of shares of ENStar Common Stock that may be issued
under all awards granted under the Plan is 300,000 (subject to adjustment as
described below). If any shares of ENStar Common Stock subject to any award or
to which an award relates are not purchased or are forfeited, or if any such
award terminates without the delivery of shares, the shares previously set aside
for such awards will be available for future awards under the Plan.
Notwithstanding the foregoing, the total number of shares of ENStar Common Stock
that may be purchased upon exercise of incentive stock options granted under the
Plan may not exceed 300,000, subject to adjustment as described below and in
Section 422 or 424 of the Code or any successor provision. Shares relating to
awards that allow the holder to receive or purchase shares will be counted
against the aggregate number of shares available for granting awards under the
Plan.
 
     If any dividend or other distribution, recapitalization, stock split,
reverse stock split, reorganization, merger, consolidation, split-up, spin-off,
combination, repurchase, or exchange of shares of ENStar Common Stock or other
securities of ENStar, issuance of warrants or other rights to purchase shares of
ENStar Common Stock or other securities of ENStar, or other similar corporate
transaction or event affects the shares of ENStar Common Stock so that an
adjustment is appropriate in order to prevent dilution or enlargement of the
benefits or potential benefits intended to be made available under the Plan, the
Committee shall, in such manner as it deems equitable, adjust any or all of (i)
the number and type of shares (or other securities or property) which thereafter
may be made the subject of awards, (ii) the number and type of shares (or other
securities or property) subject to outstanding awards and (iii) the exercise
price with respect to any award.
 
     Termination. The Plan terminates on March 5, 2006, and no awards may be
made after that date. Unless otherwise expressly provided in the Plan or an
applicable award agreement, however, any award granted may extend beyond the end
of such period.
 
     Amendment. The Board of Directors may amend, alter or discontinue the Plan
at any time, provided that shareholder approval must be obtained for any such
action that, absent such shareholder approval, would (i) cause Rule 16b-3 under
the Exchange Act to become unavailable with respect to the Plan; (ii) violate
the rules or regulations of the Nasdaq National Market any other securities
exchange applicable to ENStar; or (iii) cause ENStar to be unable, under the
Code, to grant incentive stock options under the Plan. The Committee may correct
any defect, supply any omission, or reconcile any inconsistency in the Plan or
any award agreement in the manner and to the extent it shall deem desirable to
carry the Plan into effect. The Committee may waive any condition of, or rights
of ENStar under any outstanding award, prospectively or retroactively, but the
Committee may not amend or terminate any outstanding award, prospectively or
retroactively, without the consent of the holder or beneficiary of the award.
 
     Federal Tax Consequences. The following is a summary of the principal
federal income tax consequences generally applicable to awards under the Plan.
 
     The grant of an option or SAR is not expected to result in any taxable
income to the recipient. The holder of an incentive stock option generally will
have no taxable income upon exercising the incentive stock option (except that a
liability may arise pursuant to the alternative minimum tax), and ENStar will
not be entitled to a tax deduction when an incentive stock option is exercised.
Upon exercising a non-qualified stock option, the optionee must recognize
ordinary income equal to the excess of the fair market value of the shares of
ENStar Common Stock acquired on the date of exercise over the exercise price,
and ENStar will be entitled at that time to a tax deduction in the same amount.
Upon exercising an SAR, the amount of any cash received and the fair market
value on the exercise date of any shares of ENStar Common Stock received are

recipient as ordinary income and deductible by ENStar. The tax consequence to an
optionee upon a disposition of shares acquired through the exercise of an option
or SAR will depend on how long the shares have been held and upon whether such
shares were acquired by exercising an incentive stock option or by exercising a
non-qualified stock option or SAR. Generally, there will be no tax consequence
to ENStar in connection with disposition of shares acquired under an option,
except that ENStar may be entitled to a tax deduction in the case of a
disposition of shares acquired under an incentive stock option before the
applicable incentive stock option holding periods set forth in the Code have
been satisfied.
 
     With respect to other awards granted under the Plan that are payable either
in cash or shares of ENStar Common Stock that are either transferable or not
subject to substantial risk of forfeiture, the holder of such an award must
recognize ordinary income equal to the excess of (i) the cash or the fair market
value of the shares of ENStar Common Stock received (determined as of the date
of such receipt) over (ii) the amount (if any) paid for such shares of ENStar
Common Stock by the holder of the award, and ENStar will be entitled at that
time to a deduction for the same amount. With respect to an award that is
payable in shares of ENStar Common Stock that are restricted as to
transferability and subject to substantial risk of forfeiture, unless a special
election is made pursuant to the Code, the holder of the award must recognize
ordinary income equal to the excess of (i) the fair market value of the shares
of ENStar Common Stock received (determined as of the first time the shares
become transferable or not subject to substantial risk of forfeiture, whichever
occurs earlier) over (ii) the amount (if any) paid for such shares of ENStar
Common Stock by the holder, and ENStar will be entitled at that time to a tax
deduction in the same amount.
 
     Special rules may apply in the case of individuals subject to Section 16 of
the Exchange Act. In particular, unless a special election is made pursuant to
the Code, shares received pursuant to the exercise of a stock option or SAR may
be treated as restricted as to transferability and subject to a substantial risk
of forfeiture for a period up to six months after the date of exercise.
Accordingly, the amount of any ordinary income recognized, and the amount of
ENStar's tax deduction, are determined as of the end of such period.
 
     Under the Plan, the Committee may permit participants (other than
non-employee directors) receiving or exercising awards, subject to the
discretion of the Committee and upon such terms and conditions as it may impose,
to surrender shares of ENStar Common Stock (either shares received upon the
receipt or exercise of the award or shares previously owned by the optionee) or
other property to ENStar to satisfy federal and state tax obligations. In
addition, the Committee may grant, subject to its discretion and such rules as
it may adopt, a bonus to a participant (other than a person subject to Section
16 of the Exchange Act) in order to provide funds to pay all or a portion of
federal and state taxes due as a result of the receipt or exercise of (or lapse
of restrictions relating to) an award. The amount of any such bonus will be
taxable to the participant as ordinary income, and ENStar will have a
corresponding deduction equal to such amount (subject to the usual rules
concerning reasonable compensation).
 
     Eligible Employees. Any employee, officer, consultant or independent
contractor of ENStar and its affiliates selected by the Committee is eligible to
receive an award under the Plan. Other than as described elsewhere herein, the
amount, type and recipients of awards under the Plan have not yet been
determined.
 
     Non-employee Directors. Each non-employee director of ENStar, upon his or
her initial election as a director, shall be granted an option to purchase 4,000
shares of ENStar Common Stock. Commencing with the 1997 Annual Meeting, each
non-employee director of ENStar also shall be granted an option to purchase
1,000 shares of ENStar Common Stock on the date of the annual meeting of
shareholders each year if the director will remain in office immediately
following such meeting. The exercise price of each option shall be equal to 100
percent of the fair market value per share on the date of grant. Such options
shall be non-qualified stock options, shall become exercisable six months after
the date of grant, and shall terminate on the fifth anniversary of the date of
grant. Such options shall also terminate three months following the date upon
which the participant ceases to be a director of ENStar, except that if the
participant shall cease to be a director by reason of willful and material
misconduct, the option shall terminate as of the date of such misconduct, and if
the participant shall die while a director of ENStar and he or she shall not
have fully exercised the option, the option may be exercised at any time within
twelve months after the participant's death, in accordance with its
 
                                       85
<PAGE>   94
 
terms by the participant's legal representatives, but only to the extent of the
full number of shares the participant was entitled to purchase under the option
on the date of death.
 
     In connection with their election as directors and the adoption of the
Plan, each of Messrs. James H. Michael, Miles E. Efron and Richard J. Braun were
granted an option to purchase 4,000 shares of ENStar Common Stock. The exercise
price of such options is at $9.00 per share. The options are expressly subject
to the consummation of the Reorganization.
 
EIZENGA AGREEMENT
 
     Gary L. Eizenga is a party to a Stock Option Agreement, dated September 27,
1989, pursuant to which he was granted an option to purchase from NSU up to 500
shares of the common stock of Americable, or approximately 2.5% of the
outstanding shares of Americable, subject to adjustment in the event of a
recapitalization, stock-split or stock dividend, at a price per share equal to
the book value per share as of September 30, 1989, which was $873.12. Such
option is exercisable through October 1, 1999, except that in the event of
termination of Mr. Eizenga's employment, the option may be exercised only for a
period of 90 days after such termination. The option may terminate as of an
earlier date in the event of dissolution or liquidation of Americable. Mr.
Eizenga and NSU are currently discussing a possible restructuring of Mr.
Eizenga's option in connection with the Reorganization.
 
DOAN AGREEMENT
 
     Gary M. Doan is a party to an employment agreement with Transition, the
original term of which expired December 31, 1994, but which has been
automatically extended by the parties for successive one-year periods since that
date. As extended, the agreement provides for an annual base salary of $120,000
in connection with Mr. Doan's services rendered for the benefit of Transition.
The agreement entitles Mr. Doan to participate in executive compensation
programs established by Transition's Board of Directors. Mr. Doan is also
eligible to receive an annual cash bonus to be determined based on Transition's
financial performance. Mr. Doan received a bonus of $24,000 based on
Transition's performance during 1995.
 
     The agreement may be terminated by either party at the end of an extension
period upon at least 60 days written notice. If Transition terminates Mr. Doan's
employment without sufficient notice or without cause, Mr. Doan is entitled to
be paid the base salary then in effect for a period of six months.
 
     In connection with Gary M. Doan's employment with Transition as of May 1,
1992, Mr. Doan was granted an option to purchase up to 4.5% of the Common Stock
of Transition at a price equal to the fair market value on May 1, 1992.
Approximately two thirds of the award was exercisable by May 1994. The remainder
is exercisable December 31, 2001. The option expires April 30, 2002, except that
in the event Mr. Doan's employment is earlier terminated for whatever reason,
the portion of the award that is exercisable or which will become exercisable
within 90 days may be exercised until the earlier of 90 days after such
termination or May 31, 2002. Any shares purchased by Mr. Doan are subject to
repurchase by NSU if Mr. Doan ceases to be employed by Transition.
 
                             PROPOSAL NUMBER FOUR:
                     PROPOSAL TO ADOPT AN AMENDMENT TO THE
                   RESTATED ARTICLES OF INCORPORATION OF NSU
 
     On March 5, 1996, the Board of Directors of NSU unanimously adopted a
resolution approving amendments to and a restatement of NSU's existing Restated
Articles of Incorporation, subject to the consummation of the Reorganization.
The Board further resolved that the amendments be submitted to shareholders of
NSU for their approval, subject to the consummation of the Reorganization. A
copy of the Amended and Restated Articles of Incorporation is included in
Appendix I as Exhibit D to the Reorganization Agreement. Such Amended and
Restated Articles of Incorporation are referred to herein as the "New Articles."
If approved by the shareholders of NSU, the New Articles would be filed with the
Minnesota Secretary of State on the Effective Date.
 
                                       86
<PAGE>   95
 
     Michael has requested the changes to the Restated Articles of Incorporation
of NSU as described below, as a condition to the Merger, in order to ensure that
the Articles of New Michael will better conform to the existing Certificate of
Incorporation of Michael. The Board of Directors of NSU believes that the
amendments are appropriate in light of the Reorganization.
 
     Under the New Articles, NSU's name will be changed to Michael Foods, Inc.
 
     Article IV of the existing Restated Articles of Incorporation of NSU would
be amended by decreasing the number of shares of authorized Capital Stock of NSU
from 100,035,000 shares, comprised of 100,000,000 shares of Common Stock with a
par value of $.25 per share and 35,000 shares of preferred stock with a par
value of $100 per share, to 50,000,000 shares comprised of 40,000,000 shares of
common stock with a par value of $.01 per share and 10,000,000 undesignated
shares. Each share of New Michael Common Stock will be entitled to one vote on
all matters presented to the shareholders for a vote. Article IV of the New
Articles would eliminate the current designation of the rights and preferences
of NSU Common Stock and NSU Preferred Stock. The Board of Directors will be able
to establish by resolution different classes or series of shares and to fix the
rights and preferences of any New Michael Preferred Stock to be issued. The
rights and preferences of New Michael Common Stock will be as provided under
Minnesota law.
 
     The current Restated Articles of Incorporation of NSU mandate that the
Board of Directors consist of at least one but not more than 15 directors.
Article VI of the New Articles will set the minimum number of directors at three
but will not fix a maximum number. It will also permit the board, in its
discretion, to elect honorary, non-voting directors. In addition, Article VI of
the New Articles will explicitly state that the Board of Directors has all the
powers conferred upon directors under the Minnesota Business Corporation Act.
 
     Under the existing Restated Articles of Incorporation of NSU, an absolute
majority of directors may take written action in lieu of action at a meeting,
except when the matter to be acted on requires shareholder approval. When an
action taken by the board must be approved by shareholders, however, a written
action must be approved by an absolute majority of directors. Under the New
Articles, a written action on a matter requiring shareholder approval must be
signed by all directors. Other matters may be acted upon by written action
signed by an absolute majority of the directors.
 
     The New Articles will also require New Michael to indemnify any person who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding, including an action by or in the right
of NSU to the fullest extent permitted under the Minnesota Business Corporation
Act. The existing Restated Articles of Incorporation of NSU do not explicitly
require such indemnification.
 
     If approved, the amendments to and restatement of the Restated Articles of
Incorporation of NSU will, subject to the consummation of the Reorganization,
become effective upon filing with the Minnesota Secretary of State, which would
take place on the Effective Date. The Board of Directors recommends a vote FOR
approval of the New Articles. Under Minnesota law the affirmative vote of a
majority of the outstanding shares of NSU Common Stock is necessary to approve
the New Articles.

                             PROPOSAL NUMBER FIVE:
                           ELECTION OF NSU DIRECTORS
 
     The Board of Directors of NSU has recommended that the number of Directors
to be elected for the coming year be set at six. The Board of Directors
recommends that shareholders elect the nominees named below as Directors of NSU
for the ensuing year and until their successors are elected and qualified.
Unless otherwise indicated thereon, the persons named in the enclosed form of
proxy intend to vote FOR the election of the six nominees listed below. The
affirmative vote of a majority of the shares of NSU Common Stock present (or
represented by proxy) and entitled to vote at the 1996 Annual Meeting is
required to elect each of the nominees as Directors for the ensuing year or
until their successors are elected and have qualified. All of the nominees are
members of the present Board of Directors. If for any reason any nominee shall
be unavailable for election to the Board of Directors, votes will be cast
pursuant to authority granted by the enclosed proxy for such other candidate or
candidates as may be nominated by the Board of Directors. The Board of Directors
has no reason to believe that any of the nominees listed below will be unable to
serve if elected to office. If the Reorganization is consummated, NSU and
Michael currently contemplate that the members of the Board of Directors of NSU
other than Mr. Efron and Mr. Michael will resign as of the Effective Date and
Mr. Efron and Mr. Michael will name certain Michael-designated individuals to
the Board of Directors of New Michael. See "THE REORGANIZATION AGREEMENT -- New
Michael Management Following the Reorganization."

executive officers. The Committee is made up of three members, James H. Michael,
Miles E. Efron and Jeffrey J. Michael. With respect to compensation matters
concerning Mr. Jeffrey J. Michael, NSU's President and Chief Executive Officer,
Mr. Jeffrey J. Michael is excluded from Committee deliberations. After
consideration of the Committee recommendations, the full Board of Directors
reviews and approves the salaries of each named executive officer. The Committee
is responsible for administering all other elements of executive compensation,
including annual incentive awards and stock option grants.
 
     Executive Compensation Philosophy and Goals. During 1991 NSU initiated a
strategic process to strengthen its balance sheet and focus its management
resources on its key holdings. In connection with this process NSU sold several
of its smaller businesses and substantially cut corporate overhead. As a result,
NSU has only two executive officers, Jeffrey J. Michael, President and Chief
Executive Officer, and Peter E. Flynn, Executive Vice President, Chief Financial
Officer and Secretary. The Committee believes that NSU's success depends to a
significant extent on the continuing efforts and dedication of Messrs. Jeffrey
J. Michael and Flynn. The executive compensation arrangements are designed to
motivate and reward these executives for attaining the financial and strategic
objectives essential to NSU's success and continued growth, while at the same
time allowing NSU to retain high-caliber executives. The key components of NSU's
compensation program are base salary, cash bonuses and, to a lesser extent,
stock option awards.
 
     Base Salaries. While the Committee has not conducted formal independent
salary comparisons in determining individual executive compensation, the
Committee believes that base salaries should be moderate, yet competitive in
relation to salaries commanded by persons in similar positions. The base salary
for each named executive officer is reviewed annually and is set on the basis of
personal performance, the relative importance of the functions the officer
performs, the scope of the officer's ongoing responsibilities and the estimated
salary levels in effect at comparable companies for comparable positions. The
weight given to each of these factors varies between individuals.
 
     Cash Bonuses. Annual cash bonuses are designed to reward executives with
operating responsibility for personal contributions to the success of NSU and
generally are earned under a structured formula. Historically, individual
performance targets have been established based on an annual operating budget
which is submitted for review and approval by the Chief Executive Officer of NSU
after consultation with the Committee. After the end of the calendar year, the
Chief Executive Officer has evaluated actual financial performance against the
individual performance targets. In the case of Mr. Flynn, who had day-to-day
responsibility for the operation of Transition during 1995 (in addition to his
responsibilities as an executive officer of NSU), the Committee departed from
this practice in 1995 because of the change in Mr. Flynn's responsibilities on
April 1, 1995, which are described below in this report. In 1993, the Committee
discontinued payment of discretionary bonuses for officers without direct
operating responsibility. Accordingly, Mr. Michael has not received a cash bonus
since 1992.
 
     Stock Options. Incentive stock options are periodically granted to motivate
executives to achieve positive long-term financial results, thereby enhancing
shareholder value. Due to the limited corporate staff, NSU does not have formal
policies or formulas for determining the timing, amount or particular vesting
schedules for stock option awards. Furthermore, NSU's stock performance is
significantly affected by changes in the value of its equity holdings in Michael
and, to a lesser extent, the value of its CorVel holdings. Although North Star
has representatives on the boards of directors of both Michael and CorVel, NSU
does not have direct
 
                                       91
<PAGE>   100
 
management control over the operations of either business. Accordingly, the
Committee believes that NSU's stock performance is often not the best indicator
of the performance of NSU's management team, and, as a result, has not granted
significant options to NSU's executives. Further, because of the substantial
beneficial holdings of Mr. Michael's family in NSU's Common Stock, the Committee
believes Mr. Michael's interests in stock performance already parallel those of
NSU's other shareholders. As a result, the Committee historically has not
granted any stock options to Mr. Michael. During 1995, there were no stock
options granted to any executive officer.
 
     1995 Executive Compensation. Mr. Jeffrey J. Michael, as Chief Executive
Officer of North Star, has overall responsibility for the strategic direction of
NSU and for the performance of NSU's wholly owned operating companies. Mr.
Michael was elected to his present position in December 1990 and is not a party
to an employment agreement. During 1994 and 1995, Mr. Michael was paid a base
salary of $235,000. In establishing Mr. Michael's base salary, the Committee
took into account that Mr. Michael does not participate in NSU's incentive cash
bonus program or employee stock option plan. Mr. Michael's base salary was
continued at $235,000 in 1996.
 
     As described in more detail below, Mr. Flynn entered into an employment
agreement with NSU and Transition effective April 1, 1993, in connection with
his assumption of the duties of President of Transition, which agreement was
modified effective as of April 1, 1995. The modification to his agreement with
NSU and Transition provided that Mr. Flynn devote more of his time to NSU
matters while continuing to oversee the day-to-day operations of Transition.
During 1995, approximately 24% of Mr. Flynn's base salary was paid by Transition
and related to his work as President of that company. The remainder of his base
salary in 1995 was paid by NSU recognizing his greater involvement in NSU
matters. In 1995, Mr. Flynn's base salary remained relatively unchanged from his
base salary in 1994. Also, for 1995, Mr. Flynn was awarded a bonus of $25,000
based on the performance of Transition through the first quarter of 1995, and a
discretionary bonus of $75,000, based on his performance in executing NSU's
strategic plans.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     Jeffrey J. Michael, James H. Michael and Miles E. Efron served on the
Executive Committee of NSU for the past fiscal year. The Executive Committee
determines compensation levels for NSU's executive officers. Each of Messrs.
James H. Michael and Efron was formerly an executive officer of NSU, and James
H. Michael has on occasion borrowed funds from NSU. As of February 21, 1996, Mr.
Michael owed NSU approximately $157,872. The maximum amount of such
indebtedness, including accrued but unpaid interest, owed to NSU by Mr. Michael
during 1995 was approximately $428,084. The currently outstanding indebtedness
is evidenced by an unsecured note which provides for quarterly interest payments
and an annual principal payment of $50,000. The unsecured note accrues interest
at the rate of one percent over the reference rate of First Bank, National
Association (9.25% at February 21, 1996).
 
     Effective September 1, 1985, the Board of Directors established a formal
policy governing future loans to officers. The policy permits unsecured loans to
officers of up to $50,000. Loans in excess of $50,000 must be approved in
advance by the Board of Directors and must be secured by readily marketable
negotiable securities. Loans to officers will bear interest at one percent over
the prevailing prime rate of interest and must mature within five years.
Interest is to be paid quarterly. In addition to the foregoing, an officer may
borrow annually an amount not exceeding 10 percent of annual compensation. These
loans are without interest and are payable on termination of employment. Mr.
James H. Michael's loans from NSU predate this policy.

     Although Jeffrey J. Michael, NSU's President and Chief Executive Officer,
served on NSU's Executive Committee during 1993 and 1994, as previously
indicated, he did not participate in any decisions regarding his own
compensation as an executive officer.

EMPLOYMENT CONTRACTS AND TERMINATION OF EMPLOYMENT ARRANGEMENTS
 
     Effective December 31, 1990, Mr. Efron's employment agreement with NSU was
terminated, and he resigned as President and Chief Executive Officer of NSU. Mr.
Efron continues as an employee of NSU, providing advisory and consulting
services. Pursuant to an agreement with NSU, he continues to receive annual
compensation of $50,000 through December 1996 for his consulting and advisory
services to NSU and is eligible to participate in other fringe benefits
established by NSU for its executive officers.
 
     Mr. Flynn is a party to an employment agreement with NSU and Transition,
which terminates December 31, 1997, subject to annual extensions thereafter at
the option of the parties. Mr. Flynn's employment agreement was modified
effective April 1, 1995. As modified, the agreement provides for an annual base
salary of $136,000 for services rendered for the benefit of NSU, plus annual
compensation of $42,500 in connection with Mr. Flynn's duties as President and
Chief Operating Officer of Transition. The agreement entitles Mr. Flynn to
participate in other fringe benefits established by NSU for its executive
officers. In addition, Mr. Flynn was awarded a bonus of $25,000 based on the
performance of Transition through the first quarter of 1995, and Mr. Flynn was
made eligible for a discretionary bonus in 1996 based upon his performance in
1995 in executing NSU's strategic plans. Under the terms of the agreement, the
amount of the discretionary bonus was limited to $75,000, as determined by NSU's
Board of Directors. The Board subsequently determined that Mr. Flynn should be
awarded the maximum amount of the discretionary bonus.
 
     Upon the voluntary termination of his employment with NSU, Mr. Flynn is
entitled to receive a single lump sum payment equal to his then current base
salary plus $25,000. If Mr. Flynn dies, he becomes disabled and unable to
continue his employment, his employment is terminated by NSU for any reason, or
he voluntarily terminates his employment following certain actions by NSU
constituting constructive termination, Mr. Flynn is entitled to receive a single
lump sum payment equal to two times his then current base salary plus $25,000.
If Mr. Flynn's employment is terminated due to a change in control of NSU, Mr.
Flynn is entitled to receive a single lump sum payment of $297,000. Also, if Mr.
Flynn is terminated by NSU, all of his then outstanding options immediately
become vested.

COMPLIANCE WITH SECTION 16(A) OF THE EXCHANGE ACT
 
     Section 16(a) of the Securities Exchange Act of 1934 requires executive
officers and directors and persons who beneficially own more than ten percent
(10%) of NSU's Common Stock to file initial reports of ownership and reports of
changes in ownership with the Commission. Executive officers, directors, and
greater than ten percent (10%) beneficial owners are required by Commission
regulations to furnish NSU with copies of all Section 16(a) forms they file.
 
     Based solely on a review of the copies of such forms furnished to NSU and
written representations from the executive officers and directors of NSU, NSU
believes that its executive officers, directors and 10% shareholders complied
with all Section 16(a) filing requirements applicable to them, except that
Messrs. James H. Michael and Jeffrey J. Michael each reported one transaction
late for the year ending December 31, 1995.

                      AGREEMENT AND PLAN OF REORGANIZATION
 
     AGREEMENT AND PLAN OF REORGANIZATION dated December 21, 1995, by and

UNIVERSAL, INC., a Minnesota corporation ("NSU"), and NSU MERGER CO., a Delaware
corporation and a wholly-owned subsidiary of NSU ("Merger Sub")
 
                              W I T N E S S E T H:
 
     WHEREAS, the Boards of Directors of Michael and NSU have determined that it
is in the best interests of Michael and NSU and their respective shareholders to
consummate the merger (the "Merger") of Merger Sub, a newly-formed subsidiary of
NSU, with and into Michael with Michael as the surviving corporation;
 
     WHEREAS, Michael and NSU desire that the Merger be made on the terms and
subject to the conditions set forth in this Agreement and qualify as a
reorganization within the meaning of Section 368(a) of the Internal Revenue Code
of 1986, as amended;
 
     WHEREAS, as a condition of the Merger, Michael requires that NSU distribute
and NSU is willing to distribute immediately after the Merger to NSU
shareholders of record prior to the Merger, all of the capital stock of a newly
incorporated wholly owned subsidiary, to which, prior to the Merger, all of the
assets of NSU will be assigned, contributed or otherwise transferred other than
(i) the shares of Merger Sub, (ii) the shares of Michael Common Stock (defined
below) owned by NSU on the date hereof, (iii) cash held by NSU, and (iv) certain
other assets as the parties mutually agree, and that NSU be released from, or
mutually acceptable adequate provisions be made for, all liabilities and
obligations other than as mutually agreed by the parties, so that, after giving
effect to the Merger and such distribution, the business and operations of NSU
after the Merger will be the business and operations of Michael;
 
     WHEREAS, the distribution contemplated by the previous WHEREAS clause will
be made in accordance with the Distribution Agreement (as defined below);
 
     WHEREAS, as a further condition of the Merger, Michael requires and NSU is
willing to reduce the number of outstanding shares of NSU Common Stock (as
defined below) to an amount equal to the number of shares of Michael Common
Stock owned by NSU less a number of shares determined by formula to reflect the
amount of the liabilities retained by NSU at the time of the Merger net of the
cash retained by NSU at the time of the Merger; and
 
     WHEREAS, Michael is requiring such reduction in the number of outstanding
shares of NSU Common Stock so that each share of Michael Common Stock will be
exchangeable for one share of the Surviving Corporation Common Stock (as defined
below) after the Merger.
 
     NOW, THEREFORE, in consideration of the representations, warranties and
covenants contained herein, the parties hereto agree as follows:

     2.3 Rights of Holders of Michael Capital Stock.
 
     (a) On and after the Effective Date and until surrendered for exchange,
each outstanding stock certificate which immediately prior to the Effective Date
represented shares of Michael Common Stock shall be deemed for all purposes, to
evidence ownership of and to represent the number of whole shares of the
Surviving Corporation Common Stock into which such shares of Michael Common
Stock shall have been converted, and the record holder of such outstanding
certificate shall, after the Effective Date, be entitled to vote the shares of
the Surviving Corporation Common Stock into which such shares of Michael Common
Stock shall have been converted on any matters on which the holders of record of
the Surviving Corporation Common Stock, as of any date subsequent to the
Effective Date, shall be entitled to vote. In any matters relating to such
certificates of Michael Common Stock, the Surviving Corporation may rely
conclusively upon the record of shareholders maintained by Michael containing
the names and addresses of the holders of record of Michael Common Stock on the
Effective Date.
 
     (b) On and after the Effective Date, the Surviving Corporation shall
reserve a sufficient number of authorized but unissued shares of the Surviving
Corporation Common Stock for issuance in connection with the conversion of
Michael Common Stock into the Surviving Corporation Common Stock and the shares
of Michael Common Stock reserved for issuance under the Michael Stock Plans,
including the shares issuable upon exercise of the Continuing Options.
 
     2.4 Procedure for Exchange of Stock.
 
     (a) After the Effective Date, holders of certificates theretofore
evidencing outstanding shares of Michael Common Stock, upon surrender of such
certificates to an exchange agent appointed by Michael (the "Exchange Agent"),
shall be entitled to receive certificates representing the number of whole
shares of the Surviving Corporation Common Stock into which shares of Michael
Common Stock theretofore represented by the certificates so surrendered shall
have been converted as provided in Section 2.2(a) hereof. As soon as practicable
after the Effective Date, the Surviving Corporation shall cause the Exchange
Agent to mail appropriate and customary transmittal materials (which shall
specify that delivery shall be effected, and risk of loss and title to the
certificates theretofore representing shares of Michael Common Stock shall pass,
only upon proper delivery of such certificates to the Exchange Agent) to each
holder of Michael Common Stock of record as of the Effective Date advising such
holder of the effectiveness of the Merger and the procedure for surrendering to
the Exchange Agent outstanding certificates formerly evidencing ownership of the
Michael Common Stock in exchange for new certificates evidencing ownership of
the Surviving Corporation Common
 
                                       I-7

Stock. The Surviving Corporation shall not be obligated to deliver the
consideration to which any former holder of shares of Michael Common Stock is
entitled as a result of the Merger until such holder surrenders the certificate
or certificates representing such shares for exchange as provided in such
transmittal materials and this Section 2.4(a). Upon surrender, each certificate
evidencing Michael Common Stock shall be canceled.
 
     (b) After the Effective Date, holders of certificates theretofore
evidencing outstanding shares of NSU Common Stock subject to the Reverse Stock
Split, upon surrender of such certificates to the Exchange Agent, shall be
entitled to receive (i) certificates representing the whole number of shares of
the Surviving Corporation Common Stock into which the shares of NSU Common Stock
subject to the Reverse Stock Split so surrendered shall have been combined as a
result of the Reverse Stock Split, and (ii) cash payments in lieu of fractional
shares, if any, as provided in Section 1.4 hereof. As soon as practicable after
the Effective Date, the Surviving Corporation shall cause the Exchange Agent to
mail appropriate and customary transmittal materials (which shall specify that
delivery shall be effected, and risk of loss and title to the certificates
theretofore representing shares of NSU Common Stock subject to the Reverse Stock
Split shall pass, only upon proper delivery of such certificates to the Exchange
Agent) to each holder of NSU Common Stock subject to the Reverse Stock Split of
record as of the Effective Date advising such holder of the effectiveness of the
Merger, the Reverse Stock Split and the Distribution and the procedure for
surrendering to the Exchange Agent outstanding certificates formerly evidencing
ownership of the NSU Common Stock subject to the Reverse Stock Split in exchange
for new certificates evidencing ownership of the Surviving Corporation Common
Stock. The Surviving Corporation shall not be obligated to deliver the
consideration to which any former holder of shares of NSU Common Stock subject
to the Reverse Stock Split is entitled as a result of the Merger and the Reverse
Stock Split until such holder surrenders the certificate or certificates
representing such shares for exchange as provided in such transmittal materials
and this Section 2.4(b). Notwithstanding the immediately preceding sentence, as
provided in the Distribution Agreement and in accordance with the terms thereof,
the certificates evidencing the Spinco Common Stock shall be mailed on the
Distribution Date to the NSU shareholders of record on the Distribution Record
Date, other than holders of Dissenting Shares, and the surrender of the
certificates evidencing the NSU Common Stock subject to the Reverse Stock Split
shall not be a condition to the delivery, after the Effective Date, of the
certificates evidencing the Spinco Common Stock. Upon surrender, each
certificate evidencing NSU Common Stock subject to the Reverse Stock Split shall
be canceled.
 
     (c) On the Effective Date, the Surviving Corporation shall deposit, or
shall cause to be deposited, with the Exchange Agent, for exchange in accordance
with this Section 2.4, certificates representing the shares of the Surviving
Corporation Common Stock and cash in lieu of fractional shares (such
certificates and cash are hereinafter referred to as the "Exchange Fund") to be
issued or paid by the Surviving Corporation pursuant to Articles 1 and 2 in
connection with the Merger and the Reverse Stock Split. As provided in the
Distribution Agreement, the certificates evidencing the Spinco Common Stock
shall have been deposited by NSU with the transfer agent of NSU on or prior to
the Effective Date, for distribution on the Distribution Date in accordance with
the terms of the Distribution Agreement and the terms hereof. After the
Effective Date, the Surviving Corporation shall, on the payment or distribution
date, tender to the Exchange Agent as an addition to the Exchange Fund all
dividends and other distributions applicable to certificates held in the
Exchange Fund for shares of the Surviving Corporation Common Stock issuable in
respect of the NSU Common Stock subject to the Reverse Stock Split.
 
     (d) Until outstanding certificates representing NSU Common Stock subject to
the Reverse Stock Split are surrendered as provided in Section 2.4(b) hereof, no
dividend or distribution payable to such holders of record of NSU Common Stock,
except the Spinco Common Stock payable in connection with the Distribution,
shall be paid to any holder of such outstanding certificates, but upon surrender
of such outstanding certificates by such holder there shall be paid to such
holder the amount of any dividends or distributions (without interest)
theretofore paid with respect to the whole shares of the Surviving Corporation
Common Stock into which such shares are converted as a result of the Reverse
Stock Split, but not paid to such holder, and which dividends or distributions
had a record date occurring subsequent to the Effective Date.
 
                                       I-8
<PAGE>   117
 
     (e) After the Effective Date, there shall be no further registration of
transfers on the records of Michael of outstanding certificates formerly
representing shares of Michael Common Stock at the Effective Date (other than
the shares of the Merger Sub which are converted into Michael Common Stock
pursuant to Section 2.3(c)) and there shall be no further registration of
transfers on the records of the Surviving Corporation of outstanding
certificates representing shares of NSU Common Stock subject to the Reverse
Stock Split. If any such certificate is presented to Michael or the Surviving
Corporation, it shall be forwarded to the Exchange Agent for cancellation and
exchange for certificates representing shares of the Surviving Corporation
Common Stock as herein provided.
 
     (f) All shares of the Surviving Corporation Common Stock issued upon the
surrender for exchange of Michael Common Stock in accordance with the above
terms and conditions shall be deemed to have been issued and paid in full
satisfaction of all rights pertaining to such shares of Michael Common Stock.
All shares of the Surviving Corporation Common Stock issued upon the surrender
for exchange of NSU Common Stock subject to the Reverse Stock Split in
accordance with the above terms and conditions shall be deemed to have been
issued in full satisfaction of all rights pertaining to such shares of NSU
Common Stock.
 
     (g) Any portion of the Exchange Fund (including the proceeds of any
investments thereof, any shares of the Surviving Corporation Common Stock and
any dividends or distributions thereon) that remains unclaimed by the holders of
Michael Common Stock or NSU Common Stock subject to the Reverse Stock Split, as
the case may be, for six months after the Effective Date shall be returned or
repaid to the Surviving Corporation. Any holders of Michael Common Stock or NSU
Common Stock subject to the Reverse Stock Split who have not theretofore
complied with this Section 2.4 shall thereafter look only to the Surviving
Corporation for issuance of their shares of the Surviving Corporation Common
Stock, cash in lieu of fractional shares and any unpaid dividends and
distributions on the Surviving Corporation Common Stock deliverable in respect
of the shares of NSU Common Stock subject to the Reverse Stock Split that such
holder holds as determined pursuant to this Agreement, in each case, without any
interest thereon. If outstanding certificates for shares of Michael Common Stock
or NSU Common Stock subject to the Reverse Stock Split are not surrendered or
the payment for them not claimed prior to the date on which such payments would
otherwise escheat to or become the property of any governmental unit or agency,
the unclaimed items shall, to the extent not prohibited by abandoned property
and any other applicable law, become the property of the Surviving Corporation
(and to the extent not in its possession shall be paid over to it), free and
clear of all claims or interest of any person previously entitled to such
claims. Notwithstanding the foregoing, none of Surviving Corporation, Michael,
NSU, the Exchange Agent or any other person shall be liable to any former holder
of Michael Common Stock or NSU Common Stock subject to the Reverse Stock Split
for any amount delivered to a public official pursuant to applicable abandoned
property, escheat or similar laws.
 
     (h) In the event any certificate for Michael Common Stock or NSU Common
Stock subject to the Reverse Stock Split shall have been lost, stolen or
destroyed, the Exchange Agent shall issue and pay in exchange for such lost,
stolen or destroyed certificate, upon the making of an affidavit of that fact by
the holder thereof, such shares of the Surviving Corporation Common Stock and
cash for fractional shares, if any, as may be required pursuant to this
Agreement; provided, however, that the Surviving Corporation, in its discretion
and as a condition precedent to the issuance and payment thereof, may require
the owner of such lost, stolen or destroyed certificate to deliver a bond in
such sum as it may direct as indemnity against any claim that may be made
against the Surviving Corporation, Michael, NSU, the Exchange Agent or any other
party with respect to the certificate alleged to have been lost, stolen or
destroyed.

                   REPRESENTATIONS AND WARRANTIES OF MICHAEL
 
     Michael hereby represents and warrants to NSU as follows:
 
     3.1 Organization and Qualification. Michael is a corporation duly

As used in this Agreement, the term "Charter" with respect to any corporation
shall mean those instruments that at that time constitute its charter as filed
or recorded under the general corporation or other applicable law of the
jurisdiction of its incorporation or organization, including the articles or
certificate of incorporation and any and all amendments thereto. Each of Michael
and the Michael Subsidiaries is licensed or qualified to do business in every
jurisdiction in which the nature of its business or its ownership of property
requires it to be licensed or qualified, except where the failure to be so
licensed or qualified would not have a Material Adverse Effect on Michael.
 
     3.2 Authority Relative to this Agreement; Non-Contravention. Michael has
the requisite corporate power and authority to enter into this Agreement and the
Certificate of Merger and to carry out its obligations hereunder and thereunder.
The execution and delivery of this Agreement and the Certificate of Merger by
Michael and the consummation by Michael of the transactions contemplated hereby
and thereby have been duly authorized by the Board of Directors of Michael and,
except for approval of this Agreement and the Merger by the requisite vote of
Michael's shareholders, no other corporate proceedings on the part of Michael
are necessary to authorize this Agreement and the consummation of the
transactions contemplated hereby. This Agreement has been duly executed and
delivered by Michael and, assuming it is a valid and binding obligation of NSU,
constitutes a valid and binding obligation of Michael enforceable in accordance
with its terms except as enforcement may be limited by general principles of
equity whether applied in a court of law or a court of equity and by bankruptcy,
insolvency and similar laws affecting creditors' rights and remedies generally.
Except as set forth in Schedule 3.2, neither Michael nor any of the Michael
Subsidiaries is subject to, or obligated under, any provision of (a) its Charter
or Bylaws, (b) any agreement, arrangement or understanding, (c) any license,
franchise or permit or (d) subject to obtaining the approvals referred to in the
next sentence, any law, regulation, order, judgment or decree, which would be
breached or violated, or in respect of which a right of termination or
acceleration or any encumbrance on any of its assets would be created, by the
execution, delivery or performance of this Agreement, the Certificate of Merger,
or the consummation of the transactions contemplated hereby or thereby, other
than any such breaches, violations, rights of termination or acceleration or
encumbrances which, in the aggregate, could not reasonably be expected to result
in a Material Adverse Effect on Michael. Except for (a) the filing required by
the HSR Act and the termination of any waiting period thereunder, (b) the filing
with the SEC of a joint proxy statement in definitive form relating to the
meetings of Michael's and NSU's shareholders to be held in connection with this
Agreement and the transactions contemplated hereby, (c) the filing with the SEC
of the Registration Statement and effectiveness of the Registration Statement,
(d) the approval of the Merger, the Certificate of Merger and this Agreement by
the requisite vote of the shareholders of Michael (the "Requisite Michael
Shareholder Vote"), (e) approvals under applicable Blue Sky laws, (f) the filing
of the Certificate of Merger with the Delaware Secretary of State in accordance
with the DGCL, and (g) such filings, authorizations or approvals as may be set
forth in Schedule 3.2, no authorization, consent or approval of, or filing with,
any public body, court or authority is necessary on the part of Michael or any
of the Michael Subsidiaries for the consummation by Michael of the transactions
contemplated by this Agreement, except for such authorizations, consents,
approvals and filings as to which the failure to obtain or make the same will
not, in the aggregate, have a Material Adverse Effect on Michael or adversely
affect the consummation of the transactions contemplated hereby.
 
     3.3 Capitalization. The authorized, issued and outstanding shares of
capital stock of Michael as of the date hereof is correctly set forth on
Schedule 3.3. The issued and outstanding shares of capital stock of

Michael are duly authorized, validly issued, fully paid and nonassessable and
have not been issued in violation of any preemptive rights.
 
     3.4 Exchange Act Reports. Prior to the execution of this Agreement, Michael
has delivered or made available to NSU complete and accurate copies of (a)
Michael's Annual Reports on Form 10-K for the years ended December 31, 1990,
1991, 1992, 1993 and 1994 (the "Michael 10-K Reports") as filed with the SEC,
(b) all Michael proxy statements and annual reports to shareholders used in
connection with meetings of Michael shareholders held since January 1, 1991 and
(c) Michael's Quarterly Reports on Form 10-Q for the quarters ended March 31,
June 30, and September 30, 1995 (the "Michael 10-Q Reports") as filed with the
SEC. As of their respective dates or as subsequently amended prior to the date
hereof, such documents (i) did not contain any untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
to make the statements therein, in light of the circumstances under which they
were made, not misleading and (ii) complied as to form in all material respects
with the applicable rules and regulations of the SEC. Since January 1, 1991,
Michael has filed in a timely manner all reports that it was required to file
with the SEC pursuant to the Exchange Act, as amended, and the rules and
regulations promulgated thereunder. The Michael financial statements (including
any footnotes thereto) contained in the Michael 10-K Reports and the Michael
10-Q Reports were prepared in accordance with GAAP applied on a consistent basis

                     REPRESENTATIONS AND WARRANTIES OF NSU
 
     NSU hereby represents and warrants to Michael as follows:
 
     4.1 Organization and Qualification. NSU is a corporation duly organized,
validly existing and in good standing under the laws of the State of Minnesota,
and has the requisite corporate power to carry on its business as now conducted.
Each of the NSU Subsidiaries is a corporation duly organized, validly existing
and in good standing under the laws of the state of its incorporation. The
copies of the Charter and Bylaws of NSU and Merger Sub which have been made
available to Michael on or prior to the date of this Agreement are correct and
complete copies of such documents as in effect as of the date of this Agreement.
Each of NSU and the NSU Subsidiaries is licensed or qualified to do business in
every jurisdiction in which the nature of its business or its ownership of
property requires it to be licensed or qualified, except where the failure to be

the Merger Sub and Spinco has the requisite corporate power and authority to
enter into this Agreement, the Certificate of Merger and the Distribution
Agreement to which it is or will be a party and to carry out its obligations
hereunder and thereunder. The execution and delivery of this Agreement, the
Certificate of Merger and the Distribution Agreement by NSU, the Merger Sub and
Spinco to which it is or will be a party, and the consummation by NSU, the
Merger Sub and Spinco of the transactions contemplated hereby and thereby have
been duly authorized by the Boards of Directors of NSU, the Merger Sub and
Spinco. Except for approval of this Agreement, the Merger, the New Articles, the
Reverse Stock Split and the Distribution by the requisite vote of NSU's
shareholders, no other corporate proceedings on the part of NSU, Merger Sub or
Spinco are necessary to authorize this Agreement, the Certificate of Merger and
the Distribution Agreement and the consummation of the transactions contemplated
hereby and thereby. This Agreement has been duly executed and delivered by NSU
and Merger Sub and, assuming it is a valid and binding obligation of Michael,
constitutes a valid and binding obligation of NSU and Merger Sub enforceable in
accordance with its terms except as enforcement may be limited by general
principles of equity whether applied in a court of law or a court of equity and
by bankruptcy, insolvency and similar laws affecting creditors' rights and
remedies generally. Except as set forth in Schedule 4.2, neither NSU nor any of
the NSU Subsidiaries is subject to, or obligated under, any provision of (a) its
Charter or Bylaws, (b) any agreement, arrangement or understanding, (c) any
license, franchise or permit or (d) subject to obtaining the approvals referred
to in the next sentence, any law, regulation, order, judgment or decree, which
would be breached or violated, or in respect of which a right of termination or
acceleration or any encumbrance on any of its assets would be created, by the
execution, delivery or performance of this Agreement, the Certificate of Merger,
the Distribution Agreement or the consummation of the transactions contemplated
hereby or thereby, other than any such breaches, violations, rights of
termination or acceleration or encumbrances which, in the aggregate, could not
reasonably be expected to have a Material Adverse Effect on NSU. Except for (a)

the shares of Spinco Common Stock to be distributed in the Distribution, if

Reverse Stock Split and the Distribution by the requisite vote of the
shareholders of NSU (the "Requisite NSU Shareholder Vote"), (d) the filing of
the New Articles with the Minnesota Secretary of State, and (e) such filings,
authorizations or approvals as may
 
                                      I-12

be set forth in Schedule 4.2, no authorization, consent or approval of, or
filing with, any public body, court or authority is necessary on the part of NSU
or any of the NSU Subsidiaries for the consummation by NSU or the Merger Sub of
the transactions contemplated by this Agreement, except for such authorizations,
consents, approvals and filings as to which the failure to obtain or make the
same will not, in the aggregate, have a Material Adverse Effect on NSU or
adversely affect the consummation of the transactions contemplated hereby.
 
     4.3 Capitalization. The authorized, issued and outstanding shares of
capital stock of each of NSU and Merger Sub as of the date hereof is correctly
set forth on Schedule 4.3. The issued and outstanding shares of capital stock of

conversion privileges or other rights, agreements, arrangements or commitments
obligating NSU or Merger Sub to issue, sell, purchase or redeem any shares of
its capital stock or securities or obligations of any kind convertible into or
exchangeable for any shares of its capital stock. Schedule 4.3 contains true and
correct copies of all such agreements, arrangements (including all stock plans,
but excluding individual stock option agreements) or commitments. The

                                      I-16
<PAGE>   125
 
the earliest practicable date. NSU agrees to provide Michael with reasonable
opportunity to review and comment on the Registration Statement and any
amendment thereto before filing with the SEC or any other governmental entity
and agrees not to make such filing if Michael reasonably objects to the
completeness or accuracy of any information contained therein. Michael

NSU for the purpose of inclusion in the Prospectus/Proxy Statement. NSU shall
advise Michael promptly when the Registration Statement has become effective and
of any supplements or amendments thereto, and NSU shall furnish Michael with
copies of all such documents. Prior to the Effective Date or the termination of

letter relating to the financial statements of Michael included in the
Registration Statement from Grant Thornton LLP, Michael's independent auditors,
dated a date within two business days before the date on which the Registration

delivered by independent public accountants in connection with registration
statements similar to the Registration Statement.

preparation and mailing of the Prospectus/Proxy Statement to Michael

expenses in connection with the Registration Statement.
 
     6.5 Accounting and Tax Treatment. Neither NSU nor Michael, nor Surviving
Corporation after the Effective Date, shall, directly or indirectly, voluntarily
take any action which would disqualify the Merger, the Reverse Stock Split and
the Distribution as a business combination utilizing the reverse acquisition
concept with Michael being the accounting acquiror for accounting purposes and
the Merger as a "reorganization" that would be tax free to the shareholders of
NSU and Michael pursuant to Section 368(a) of the Code.
 
     6.6 Michael Stock Plans. At or prior to the Effective Time, NSU shall take
all corporate action necessary to authorize and reserve for issuance a
sufficient number of shares of the Surviving Corporation Common Stock, equal to
the number of shares of Michael Common Stock reserved for issuance under the
Michael Stock Plans to be adopted and assumed by the Surviving Corporation at
the Effective Time, including the shares issuable upon exercise of the
Continuing Options, in accordance with Section 2.2(b).

form and substance of any press release related to this Agreement or the
transactions contemplated hereby, and shall consult with each other as to the
form and substance of other public disclosures which may relate to the
transactions contemplated by this Agreement, provided, however, that nothing
contained herein shall prohibit either party, following notification to the
other party, from making any disclosure which is required by law or regulation.
 
     6.8 Directors and Officers Insurance. Each of NSU and Michael will use its
reasonable efforts to obtain a quote for "tail policy" coverage for a period of
three years after the Effective Date under its officers and directors liability
insurance for claims asserted after the Effective Date against any person who
was an officer or director of NSU or any NSU Subsidiary prior to the Effective
Date which claims relate to the period prior to the Effective Date. If such
coverage is available, NSU will, prior to the Effective Date, select which
coverage it prefers and purchase or reimburse Michael for the cost of such
coverage.

with the SEC. Upon delivery of any such report or document, the delivering party
shall be deemed to have made the representations to the receiving party with
respect thereto as set forth in Sections 3.4 and 4.4, respectively.
 
     6.10 Stock Listing. NSU shall use all reasonable efforts to list on the
NASDAQ-NMS the shares of the Surviving Corporation Common Stock to be issued in

referred to in this sentence, or withdraw, modify or change any such
recommendation, if such Board of Directors determines, after consultation with
counsel, that the making of such recommendation, the seeking to obtain such

recommendation, is reasonably likely to constitute a breach of the fiduciary or
legal obligations of such Board of Directors.

other than the Michael Common Stock owned by NSU; provided that NSU may engage
in such discussion in response to an unsolicited proposal from an unrelated
party if the Board of Directors of NSU determines, after consultation with
counsel, that the failure to engage in such discussions is reasonably likely to
constitute a breach of the fiduciary or legal obligations of the Board of
Directors of NSU. NSU will promptly advise Michael if it receives a proposal or
inquiry with respect to the matters described above.

     (a) Each party shall give prompt notice to the other party of (i) the
occurrence or failure to occur of any event or the discovery of any information,
which occurrence, failure or discovery would be likely to cause any
representation or warranty on its part contained in this Agreement to be untrue,
inaccurate or incomplete after the date hereof in any material respect or, in
the case of any representation or warranty given as of a specific date, would be
likely to cause any such representation or warranty on its part contained in
this Agreement to be untrue, inaccurate or incomplete in any material respect as
of such specific date, and (ii) any material failure of such party to comply
with or satisfy any covenant or agreement to be complied with or satisfied by it
hereunder.
 
     (b) From time to time after the date hereof and prior to the Effective
Time, each party shall promptly supplement or amend any of its representations
and warranties which apply to the period after the date hereof by delivering an
updated Schedule to the other party pursuant to this Section 6.19(b) with
respect to any matter hereafter arising which would render any such
representation or warranty after the date of this Agreement materially untrue,
inaccurate or incomplete as a result of such matter arising. Such supplement or
amendment to a party's representations and warranties contained in an updated
Schedule delivered pursuant to this Section 6.19(b) shall be deemed to have
modified the representations and warranties of the disclosing party, and no such
supplement or amendment, or the information contained in such updated Schedule,
shall constitute a breach of a representation or warranty of the disclosing
party; provided that no such supplement or amendment may cure any breach of a
covenant or agreement of any party under Articles 5 or 6. Within fifteen (15)
days after receipt of such supplement or amendment, the receiving party may
terminate this Agreement pursuant to Section 7.1(g) hereof if (i) the
information in such supplement or amendment together with the information in any
and all of the supplements or amendments previously provided by the
 
                                      I-19

reasonably likely to suffer a Material Adverse Effect or, in the case of an
updated Schedule 4.12 is, in Michael's reasonable determination a material
liability, and (ii) the disclosing party has not cured the matters giving rise
to such termination within fifteen (15) days after the receiving party notifies
the disclosing party that it is exercising its right to terminate this Agreement
under this Section 6.19(b).
 
     6.20 Notification of Anticipated NSU Net Indebtedness. No later than thirty
(30) days after the initial filing of the Registration Statement, NSU shall

     distribution, or a transaction that has the effect of such a distribution,
     to which Sections 301, 305(b) or 305(c) apply. As a result, no taxable
     income will be recognized under such Sections by any of the stockholders of

                               DISPUTE RESOLUTION
 
     10.1 Mediation and Binding Arbitration. If a dispute arises between NSU and
Michael as to the interpretation of this Agreement or any other agreement
entered into pursuant hereto, NSU and Michael agree to use the following
procedures, in lieu of either party pursuing other available remedies and as the
sole remedy, to resolve the dispute.
 
     10.2 Initiation. A party seeking to initiate the procedures shall give
written notice to the other party, describing briefly the nature of the dispute.
A meeting shall be held between the parties within 10 days of the receipt of
such notice, attended by individuals with decision-making authority regarding
the dispute, to attempt in good faith to negotiate a resolution of the dispute.
 
     10.3 Submission to Mediation. If, within 30 days after such meeting, the
parties have not succeeded in negotiating a resolution of the dispute, they
agree to submit the dispute to mediation in accordance with the Center for
Public Resources Model ADR Procedure -- Mediation of Business Disputes, as
modified herein, and to bear equally the costs of the mediation.
 
     10.4 Selection of Mediator. The parties will jointly appoint a mutually
acceptable mediator, seeking assistance in such regard from the Center for
Public Resources or another mutually agreed-upon organization if they have been
unable to agree upon such appointment within 20 days from the conclusion of the
negotiation period.
 
     10.5 Mediation and Arbitration. The parties agree to participate in good
faith in the mediation and negotiations related thereto for a period of 30 days
following the initial mediation session. If the parties are not successful in
resolving the dispute through the mediation by the end of such 30-day period,
then the parties agree to submit the matter to binding arbitration in accordance
with the Center for Public Resources Rules for Non-Administered Arbitration of
Business Disputes, as modified herein, by a panel of three arbitrators, in
Minneapolis, Minnesota, selected in accordance with the provisions of Section
10.6 hereof. The arbitration shall be governed by the Rules of the American
Arbitration Association then in effect and as modified herein, and judgment upon
the award rendered by the arbitrator may be entered by any court having
jurisdiction thereof. The arbitrators shall not, under any circumstances, have
any authority to award punitive, exemplary or
 
                                      I-26
<PAGE>   135
 
similar damages and may not, in any event, make any ruling, finding or award
that does not conform to the terms and conditions of this Agreement. Nothing
contained in this Article 10 shall limit or restrict in any way the right or
power of a party at anytime to seek injunctive relief in any court and to
litigate the issues relevant to such request for injunctive relief before such
court (i) to restrain the other party from breaching this Agreement or (ii) for
specific enforcement of this Article 10. The parties agree that any legal remedy
available to a party with respect to a breach of this Article 10 will not be
adequate and that, in addition to all other legal remedies, each party is
entitled to an order specifically enforcing this Article 10.
 
     10.6 Selection of Arbitrators. The parties shall have 10 days from the end
of the mediation period to agree upon mutually acceptable neutral persons not
affiliated with either of the parties to act as arbitrators. If the panel of
arbitrators has not been selected within such time, the parties agree jointly to
request the Center for Public Resources or another mutually agreed-upon
organization to supply within 10 days a list of potential arbitrators with
qualifications as specified by the parties in the joint request. Within five
days of receipt of the list, the parties shall independently rank the proposed
candidates, shall simultaneously exchange rankings, and shall select as the
arbitrator the individual receiving the highest combined ranking who is
available to serve. Neither party nor the arbitrators may disclose the existence
or results of any arbitration under this Agreement or any evidence presented
during the course of arbitration without the prior consent of both parties,
except as required to fulfill applicable disclosure and reporting requirements,
or as otherwise required by law.
 
     10.7 Cost of Arbitration. Each party shall bear its own costs incurred in
the arbitration. If either party refuses to submit to arbitration any dispute
required to be submitted to arbitration pursuant to this Article 10, and instead
commences any other proceeding, including litigation, then the party who seeks
enforcement of the obligation to arbitrate shall be entitled to its attorneys'
fees and costs incurred in any such proceeding.
 
     IN WITNESS WHEREOF, NSU and Michael have caused this Agreement to be
executed on the date first written above by their respective officers.

"Agreement"), is entered into by and between NORTH STAR UNIVERSAL, INC., a

corporation and a wholly owned subsidiary of NSU ("Spinco"). This Agreement is
intended to survive and continue after the "Merger" and the "Distribution" (as
such terms are hereinafter defined), and any reference to NSU in this Agreement
shall be deemed to include NSU from and after the consummation of the Merger and
the change of the name of NSU to "Michael Foods, Inc."
 
     WHEREAS, NSU is a party to an Agreement and Plan of Reorganization dated
December 21, 1995 (the "Merger Agreement"), providing for the merger (the
"Merger") of NSU Merger Co. ("Merger Sub"), a Delaware corporation and a newly
formed and wholly-owned subsidiary of NSU, with and into Michael Foods, Inc., a
Delaware corporation ("Michael"), with Michael as the surviving corporation;
 
     WHEREAS, Michael has required that, as a condition of the Merger, the
non-food businesses, including assets and liabilities, be separated from the
food business of NSU represented by the shares of common stock of Michael owned
by NSU;
 
     WHEREAS, to satisfy this condition to the Merger, the parties hereto have
agreed that (i) immediately following the Merger, NSU will distribute to NSU
shareholders of record prior to the Merger, all assets of NSU other than (A) any

(B) the shares of common stock, $.01 par value, of Michael ("Michael Common
Stock") owned by NSU as of the date of the Merger Agreement, (C) a certain
amount of cash held by NSU at the time of the consummation of the Merger, and
(D) such other assets as to which the parties may mutually agree, and (ii) NSU
will be released from, or adequate provisions be made for all liabilities and
obligations of NSU other than as mutually agreed by the parties, so that after
giving effect to the Merger and such distribution, the business and operations
of NSU after the Merger will be the business and operations of Michael, except
for certain known and specified NSU indebtedness and certain obligations and
liabilities to be retained by NSU subsequent to the consummation of the Merger;

     to all of the NSU Transferred Assets.
 
          (ii) NSU shall assign and transfer, and Spinco shall assume, all of
     NSU's rights, benefits and Liabilities arising pursuant to and under all
     contracts, agreements, real and personal property leases, licenses,

     Contracts"); provided, however, that no Assumed Contract shall be assigned
     contrary to law or the terms of such Assumed Contract and, with respect to
     the Assumed Contracts that cannot be assigned or novated to Spinco on the
     Transfer Effective Date, the performance obligations of NSU thereunder
     shall, unless not permitted by such Assumed Contract, be subcontracted or
     subleased to Spinco until such Assumed Contract has been fully performed by
     Spinco or assigned or novated. NSU and Spinco shall use reasonable efforts
     to obtain all necessary consents and Spinco shall take all necessary
     actions to perform and complete all Assumed Contracts in accordance with

     (b) Whether or not all of the NSU Transferred Assets or the NSU Transferred

Effective Date, NSU and Spinco agree that, as of the Transfer Effective Date,
Spinco shall have, and shall be deemed to have acquired, complete and sole
beneficial ownership over all the NSU Transferred Assets together with all of
NSU's rights, powers and privileges incident thereto, and shall be deemed to
have assumed the NSU Transferred Liabilities and all of NSU's duties,
obligations and responsibilities incident thereto.
 
     Section 2.03 Elimination of Intercompany Accounts. All intercompany
receivables, payables and loans in existence as of the Merger Effective Date
between NSU, on the one hand, and any NSU Subsidiary, on the other hand (other

Transfers Deemed Effective as of the Distribution Date. To the extent that any

cooperate to effect such transfers and assumptions as promptly following the

understood by the parties that no party shall be liable in any manner to any
other party for any failure of any of the transfers contemplated by this Article
II to be consummated prior to the Transfer Effective Date and that this Section
2.04 shall in no way affect the indemnification obligations of the parties
pursuant to Article V. Subject to the provisions of Section 3.02, nothing herein
shall be deemed to require the transfer of any assets or the assumption of any
Liabilities which by their terms or by operation of law cannot be transferred or
assumed; provided that Spinco shall indemnify NSU against all NSU Transferred
 
                                       C-5

Liabilities pursuant to Section 5.01. In the event that any such transfer of the
NSU Transferred Assets (other than capital stock of corporations to be
transferred hereunder) or assumption of the NSU Transferred Liabilities has not
been consummated, effective as of and after the Transfer Effective Date (i) NSU
shall thereafter hold such assets for the benefit of Spinco (at the expense of
Spinco) and retain any such Liabilities for the account of Spinco, and take such
other action as may be reasonably requested by Spinco, at Spinco's expense, in
order to place such party, insofar as reasonably possible, in the same position
as would have existed had such asset or Liability been transferred as of the
Transfer Effective Date, (ii) NSU shall, at Spinco's expense, continue to be
bound under any agreements relating to the NSU Transferred Assets or NSU
Transferred Liabilities that cannot be so transferred, and (iii) unless not
permitted by law, Spinco shall pay, perform and discharge fully all obligations
of NSU thereunder from and after the Transfer Effective Date and indemnify NSU
for all indemnifiable losses arising out of such performance by Spinco pursuant
to the provisions of Article V hereto. NSU shall, without further consideration
therefor, pay and remit to Spinco promptly all monies, rights and other
considerations received in respect of any such performance. NSU shall exercise
its rights and options under any such agreements relating to the NSU Transferred
Assets or NSU Transferred Liabilities only as reasonably directed by Spinco, and
at Spinco's expense. As and when any such asset or liability becomes
transferable, such transfer shall be effected forthwith. Notwithstanding the
foregoing, the parties shall use their best efforts to obtain all consents and
approvals, to enter into all amendatory agreements and to make all filings and
applications which may be required for the consummation of the transactions
contemplated by this Agreement, including, without limitation, all applicable
regulatory filings or consents under federal or state environmental laws.
 
     Section 2.05 No Representations or Warranties. Spinco understands and
agrees that NSU is not, in this Agreement or in any other agreement or document
contemplated by this Agreement or otherwise, representing or warranting in any
way (i) as to the value or freedom from encumbrance of, or any other matter
concerning, any NSU Transferred Assets or (ii) as to the legal sufficiency to
convey title to any such assets or the execution, delivery and filing of this
Agreement, including, without limitation, any Conveyancing or Assumption
Instruments, it being agreed and understood that all such assets are being
transferred AS IS, WHERE IS, and that the party to which such assets are to be
transferred hereunder shall bear the economic and legal risk that any
conveyances of such assets shall prove to be insufficient or that Spinco or any
of its Subsidiaries' title to any such assets shall be other than good and
marketable and free from encumbrances. Similarly, each party hereto understands
and agrees that no party hereto is, in this Agreement or in any other agreement
or document contemplated by this Agreement or otherwise, representing or
warranting in any way that the obtaining of any consents or approvals, the
execution and delivery of any amendatory agreements and the making of any
filings or applications contemplated by this Agreement will satisfy the
provisions of any or all applicable agreements or the requirements of any or all
applicable laws or judgments, it being agreed and understood that the party to
which any assets are transferred shall bear the economic and legal risk that any
necessary consents or approvals are not obtained or that any requirements of
laws or judgments are not complied with.
 
     Section 2.06 Conveyancing and Assumption Instruments. In connection with
the transfers of the NSU Transferred Assets other than capital stock and the
assumptions of the NSU Transferred Liabilities contemplated by this Agreement,
the parties shall execute or cause to be executed by the appropriate entities
the Conveyancing and Assumption Instruments in such forms as the parties shall
agree. The transfer of capital stock shall be effected by means of delivery of
stock certificates and executed stock powers and notation on the stock record
books of the corporation.
 
     Section 2.07 Tax Treatment. During the two year period following the Merger
Effective Date, NSU shall not, nor shall it permit Michael to do any of the
following, and neither of them has any plan or intention to:
 
          (a) liquidate Michael;
 
          (b) merge Michael with or into another corporation, unless Michael is
     the surviving corporation and the merger is not treated for tax purposes as
     a sale or other disposition of Michael common stock;
 
                                       C-6
<PAGE>   148
 
          (c) sell any shares of Michael Common Stock or cause Michael to issue
     any of shares of Michael Common Stock to any party other than NSU; or
 
          (d) sell any assets of NSU to any third party not otherwise an
     affiliate of the foregoing, except for (i) sales in the ordinary course of
     business or (ii) sales of assets if, after giving effect to such sales,
     Michael will retain at least 90% of the fair market value of its gross
     assets in active trades or businesses within the meaning of Section 355 of
     the Code.
 
provided, however, NSU or Michael may undertake any of the actions listed above
if (i) Spinco consents thereto or (ii) NSU obtains either a tax opinion or a
favorable private letter ruling from the Internal Revenue Service, in each case
reasonably satisfactory to Spinco, to the effect that the actions to be
undertaken would not adversely affect the tax free nature of the Merger or the
Distribution to all of the parties thereto. The shareholders of record of NSU on
the Record Date shall be third party beneficiaries of the provisions of this
Section 2.07.

     (b) NSU and Spinco shall cooperate in preparing, filing with the Commission
and causing to become effective any registration statements or amendments
thereof which are appropriate to reflect the establishment of, or amendments to,
any employee benefit and other plans contemplated by Article VI.
 
     (c) NSU and Spinco shall take all such action as may be necessary or
appropriate under the securities or blue sky laws of states or other political
subdivisions of the United States in connection with the Distribution and the
other transactions contemplated by this Agreement.
 
     (d) NSU and Spinco shall prepare, and Spinco shall file and pursue, an
application to permit listing of the Spinco Common Stock on the NASDAQ National
Market.
 
     Section 3.02 NSU Board Action; Conditions Precedent to the
Distribution. The NSU Board shall, in its discretion, establish the Record Date,
the Transfer Effective Date and the Distribution Date (which shall be the same
as the Merger Effective Date) and any appropriate procedures in connection with
the Distribution. The Distribution is expressly conditioned on the prior
consummation of the Merger. Additionally, in no event shall the Distribution
occur (i) if at the Distribution Date NSU shall not have received an opinion of
tax counsel or a private letter ruling from the IRS to the effect that the
Distribution will qualify as a tax-free spin-off under Section 355 of the Code,
and (ii) unless prior to such time the following conditions shall have been
satisfied or waived by the parties hereto:
 
     (a) the transactions contemplated by Sections 2.02 hereof, shall have been
consummated in all material respects;
 
     (b) the Spinco Common Stock shall have been approved for quotation on the
NASDAQ National Market or listing on a national securities exchange, subject to
official notice of issuance;
 
     (c) the Spinco Board, comprised as contemplated by Section 8.01, shall have
been elected by NSU, as sole shareholder of Spinco, and the Spinco Charter and
Spinco ByLaws shall have been adopted and shall be in effect;

<PAGE>   149
 
     (d) the Registration Statement shall have been declared effective by the
Commission and the Form 8-A relating to the shares of Spinco Common Stock to be
distributed in the Distribution shall have become effective under the Exchange
Act; and
 
     (e) all conditions precedent to the obligations of NSU and Michael under
the Merger Agreement (other than consummation of the Distribution) shall have
been satisfied or waived and the Merger shall have been consummated.
 
The satisfaction or waiver of such conditions shall create an obligation on the
part of NSU to effect the Distribution on the Distribution Date.
 
     Section 3.03 The Distribution. On or prior to the Distribution Date, NSU
shall deliver to the Agent the certificate for all of the outstanding shares of
Spinco Common Stock which are owned by NSU. On the Distribution Date, after the
Effective Time of the Merger, NSU shall deliver to the Agent an instruction to
distribute as promptly as practicable following the Distribution Date to each
holder of record of NSU Common Stock on the Record Date stock certificates
evidencing such number of shares of Spinco Common Stock equal to the product of
the Exchange Ratio times the number of shares of NSU Common Stock held of record
by such holder on the Record Date and cash in lieu of any fractional share of
Spinco Common Stock obtained in the manner provided in Section 3.04 hereof. If
the number of outstanding shares of Spinco Common Stock exceeds the amount to be
distributed in the Distribution, then the remaining shares shall be deemed to
have been contributed by NSU to the capital of Spinco and retired and canceled.
Spinco agrees to provide to the Agent sufficient certificates in such
denominations as the Agent may request in order to effect the Distribution. All
of the shares of Spinco Common Stock issued in the Distribution shall be fully
paid, nonassessable and free of preemptive rights. The Distribution shall, for
all purposes under this Agreement, be deemed to have been effected at the time
NSU delivers to the Agent the instruction directing the Agent to distribute the
certificates evidencing Spinco Common Stock and cash in lieu of fractional
shares.
 
     Section 3.04 Fractional Shares. No certificate or scrip representing
fractional shares of Spinco Common Stock shall be issued as part of the
Distribution, and in lieu of receiving fractional shares each holder of NSU
Common Stock who would otherwise be entitled to receive a fractional share of
Spinco Common Stock pursuant to the Distribution will receive cash for such
fractional share. NSU and Spinco agree that NSU shall instruct the Agent to
determine the number of whole shares and fractional shares of Spinco Common
Stock allocable to each holder of record of NSU Common Stock as of the Record
Date, to aggregate all such fractional shares into whole shares and sell the
whole shares obtained thereby in the open market pursuant to Rule 236 under the
Securities Act, if available, at then prevailing prices on behalf of holders who
otherwise would be entitled to receive fractional share interests and to
distribute to each such holder such holder's ratable share of the total proceeds
of such sale. Spinco shall bear the costs of commissions incurred in connection
with such sale. If the Agent is unable to sell such shares in the open market
pursuant to Rule 236, Spinco will pay to such holders of NSU Common Stock in
lieu of any fractional share or amount of cash determined by multiplying (a) the
average closing price per share of Spinco Common Stock on the NASDAQ National
Market during the five days following the Distribution Date times (b) the
fractional share interest to which such holder would otherwise be entitled.

                 SPINCO ASSUMPTION OF CERTAIN NSU INDEBTEDNESS
 
     Section 4.01 Assumption of Certain NSU Indebtedness. Spinco and NSU shall,
on or prior to the Distribution Date, to the extent required under any indenture
with respect to any of the outstanding debentures or any of the outstanding
subordinated extendable or fixed time certificates, execute and deliver
supplemental indentures or other agreements or instruments evidencing Spinco's
assumption of NSU's obligations with respect to such outstanding debentures and
subordinated extendable and fixed time certificates; provided, however, that as
provided herein, and as contemplated by the Merger Agreement, as between NSU and
Spinco, the NSU Indebtedness is not an NSU Transferred Liability and NSU shall
be responsible for the payment in full, in accordance with the terms thereof of
all of the NSU Indebtedness and

all Liabilities with respect to the NSU Indebtedness.

     Section 5.03 Procedure for Indemnification.
 
     (a) The Spinco Indemnified Parties or the NSU Indemnified Parties (each
referred to hereinafter as an "Indemnified Party"), as the case may be, shall
promptly give notice to the indemnifying party hereunder (the "Indemnifying
Party") after obtaining knowledge of any claim, demand or request for payment
against any Indemnified Party for any Liabilities indemnifiable hereunder and
shall permit the Indemnifying Party to pay or assume the defense of such
Liability, and any litigation arising from such Liability. Notwithstanding the
foregoing notice requirement, the right to indemnification hereunder shall not
be affected by the failure of the party seeking indemnification to give such
notice or any delay by such party in giving such notice unless, and only to the
extent that, the rights and remedies of the Indemnifying Party shall have been
prejudiced as a result of the failure to give, or the delay in giving, such
notice. The failure by an Indemnifying Party to notify the Indemnified Party of
its election to defend any such Liability within ten (10) days after notice
thereof shall have been given to the Indemnifying Party, shall be deemed a
waiver by the Indemnifying Party of its right to defend such Liability.
 
     (b) If an Indemnifying Party assumes the defense of any Liability and any
litigation that results from such Liability, then the obligations of the
Indemnifying Party as to such litigation shall include employing counsel
reasonably satisfactory to the Indemnified Party, taking all steps necessary in
the defense or settlement of such litigation and holding the Indemnified Party
harmless from and against any and all claims and expenses caused by or arising
out of any settlement approved by the Indemnified Party or any judgment in
connection with such litigation. Without the prior written consent of the
Indemnified Party, the Indemnifying Parties shall not, in the defense of any
such litigation, consent to the entry of any judgment or enter into any
settlement that does not include as an unconditional term thereof, the giving by
the claimant or the plaintiff to the Indemnified Party of a full release, in
form reasonably satisfactory to the Indemnified Party, from all liability in
respect of such litigation. The Indemnified Party shall be entitled to
participate in the defense of any litigation at its own expense. If the
defendants in any such action include both the Indemnified Party and the
Indemnifying Party and the Indemnified Party shall have reasonably concluded
that there may be legal defenses available to it which are different from or
additional to those available to the Indemnifying Party, the Indemnified Party
shall have the right, at the expense of the Indemnifying Party, to select
separate counsel reasonably satisfactory to the Indemnifying Party to assume
such additional legal defenses, and to otherwise participate in the defense of
such action on behalf of the Indemnified Party.
 
     (c) If the Indemnifying Party does not assume the defense of any Liability
within ten (10) days after the Indemnified Party gives notice thereof to the
Indemnifying Party, then the Indemnified Party may defend against such Liability
and any litigation with respect thereto, in such manner as it deems appropriate
and the Indemnified Party may settle any such litigation on such terms as it
deems appropriate and the Indemnifying Party shall, in accordance with the
provisions of Sections 5.01 or 5.02, as the case may be, reimburse the
Indemnified Party for the amount of such settlement and for all losses and
expenses, including attorney's fees, incurred by the Indemnified Party in
connection with the defense of such Liability.
 
     (d) The Indemnified Party and the Indemnifying Party agree to cooperate
with each other in resolving or attempting to resolve any claim as to which
indemnification is sought under this Agreement and will permit the other party
access to all books and records which might be useful for such purpose during
normal business hours and at the place where such books and records are normally
kept. The Indemnified Party and the Indemnifying Party further agree to make
available, at reasonable times, such of their respective employees, officers and
agents who may have knowledge of matters relating to any claim arising out of
this agreement for the purpose of providing testimony or assisting in the
preparation or prosecution of a defense to any claim by a third party as to
which indemnification is sought under this Agreement.
 
     (e) Any dispute arising between the parties hereto as to the obligations
under this Article V shall be resolved pursuant to Article X hereto. If there is
no dispute with respect to any payment under this Article V from an Indemnifying
party to an Indemnified Party, then within ten (10) days after written demand
for such payment by the Indemnified Party, the Indemnifying Party shall pay to
the Indemnified Party the amount of any loss, expense, damage or other payment
suffered, incurred or made by the Indemnified Party against which the
Indemnified Party is indemnified by the Indemnifying Party under this Article V.
In the event the
 
                                      C-10
<PAGE>   152
 
Indemnifying Party fails to pay such undisputed amount within said ten (10) day
period, or it is determined pursuant to the provisions of Article X that the
Indemnifying Party is obligated to pay an amount which it had previously
disputed, the Indemnified Party shall be entitled to collect the following from
the Indemnifying Party: (i) interest from the date of the Indemnified Party's
demand for payment on the amount owing to the Indemnified Party at the rate
equal to the reference rate as publicly announced from time to time by First
Bank National Association plus two (2) percentage points, compounded monthly,
until the full amount owing, including any interest, has been paid in full with
all payments being applied first against accrued and unpaid interest, and (ii)
all costs and expenses, including reasonable attorneys fees, incurred by the
Indemnified Party in collecting the amounts owing from the Indemnifying Party
under this Article V.
 
     Section 5.04 Set-Off Rights. If and when, as a result of the net operating
loss carryforwards properly allocable to NSU from all Tax periods prior to or
ending on the Merger Effective Date, NSU unconditionally realizes a benefit in
the form of a reduction in the federal or state income Taxes which NSU would
otherwise be obligated to pay, Spinco may set-off the amount of any such Tax
savings against any Liability of Spinco under this Agreement (including the
indemnification obligations under Section 5.01) or, in the event Spinco has
already made payments pursuant to its indemnification obligations hereunder, NSU
will reimburse Spinco for payments previously made by Spinco to or on behalf of
an NSU Indemnified Party with respect to its obligations under this Agreement.
The benefit shall not be finally and unconditionally determined for any year
until such year is closed for any future adjustment of federal income Tax
liability. Any amount set-off by Spinco or reimbursed to Spinco by NSU hereunder
shall bear interest from and after the date that such benefit was reflected on
the consolidated Tax return of NSU or taken into account in an NSU estimated Tax
payment to the date of such off-set or reimbursement at the rate of 6% per
annum. NSU shall promptly provide Spinco notice of each and every time it has
filed a Tax report or return wherein it has claimed or used such Tax benefit.

                             EMPLOYEE BENEFIT PLANS
 
     Section 6.01 The 401(k) Savings Plan. (a) As soon as practicable after the
date hereof (i) effective as of the Merger Effective Date, Spinco shall assume
and be solely responsible for, all Liabilities of NSU under the [NORTH STAR
UNIVERSAL 401(K) SAVINGS PLAN] (the "Savings Plan") and (ii) prior to the Merger
Effective Date, NSU agrees to take such actions as may be necessary in order for
Spinco or a Subsidiary of Spinco effectively to maintain and administer such
Savings Plan. Spinco and NSU shall each take, or cause to be taken, all such
actions as may be necessary or appropriate in order to establish Spinco or a
Subsidiary of Spinco as successor to NSU as to all rights, assets, duties and
Liabilities of NSU under, or with respect to, the Savings Plan, including, but
not limited to, the rights, assets, duties and Liabilities of NSU under, or with
respect to, any and all trust agreements to the extent that they relate solely
to the Savings Plan. Any action taken by NSU pursuant to this Section 6.01 after
the Merger Effective Date shall be at Spinco's expense.
 
     (b) Upon Spinco or a Subsidiary of Spinco becoming the successor employer
or successor plan sponsor to NSU or any of its subsidiaries under the Savings
Plan, NSU agrees to take such actions as may be necessary to amend any trust
agreement required to be amended in order for Spinco or a Subsidiary of Spinco
effectively to assume and administer the Savings Plan.
 
     (c) Transfers pursuant to this Section 6.01 shall be effected, where
practicable, so as to preserve each plan participant's investment election.
 
     (d) NSU and Spinco shall, in connection with the transfers described in
this Section 6.01, cooperate in making all appropriate filings required under
the Code or ERISA, and the regulations thereunder and any applicable securities
laws, and take all such action as may be necessary and appropriate to cause such
transfers to take place as soon as practicable after the Distribution Date.
 
     (e) From and after the Merger Effective Date, NSU and its Subsidiaries
thereafter shall cease to have any liability or obligation whatsoever with
respect to the Savings Plan. As provided in Article V, Spinco shall indemnify
NSU and such Subsidiaries against any such liability.

     Section 6.02 Welfare Plans.
 
     (a) Except as otherwise specifically provided in this Section 6.02, as of
the Merger Effective Date, Spinco shall assume all Liabilities of NSU in
connection with claims brought under any of NSU's or its Subsidiaries' medical,
dental, life insurance, health, accident, disability or other welfare benefit
plans in existence on or prior to the Merger Effective Date and from and after
the Merger Effective Date, NSU and its Subsidiaries thereafter shall cease to
have any such liability or obligation. From and after the Merger Effective Date,
NSU shall no longer be a participating employer in such welfare benefit plans.
 
     (b) As of the Merger Effective Date, Spinco shall assume and shall be
solely responsible for, all Liabilities of NSU in connection with claims for
post-employment welfare benefits (including, but not limited to, medical, health
and life insurance benefits) made by or in respect of (i) any Spinco Employee or
(ii) any employee of NSU prior to the Merger Effective Date who shall have
retired or whose employment otherwise terminates on or before the Merger
Effective Date, regardless of whether such claim shall relate to events which
occurred prior or subsequent to the Merger Effective Date. Spinco shall also
assume all "COBRA" continuation Liabilities of NSU as of the Merger Effective
Date.
 
     (c) Prior to the Merger Effective Date, NSU and Spinco shall take all
actions necessary and appropriate to effect the assumption of the NSU welfare
plans by Spinco or a Subsidiary of Spinco and to provide the benefit coverage
otherwise necessary to assume the Liabilities which are or shall become the
responsibility of Spinco under this Section 6.02.
 
     Section 6.03 NSU Employees. Effective as of the Merger Effective Date,
Spinco agrees to assume the employment of all employees of NSU who have not
resigned or been terminated on or prior to such date. Spinco shall assume and be
solely responsible for all Liabilities in connection with claims made by or on
behalf of such NSU employees in respect of salary, benefits, severance pay,
salary continuation and similar obligations relating to the employment or the
termination or alleged termination of the employment of any such person,
regardless of whether such termination or alleged termination occurred prior to
or subsequent to the Merger Effective Date.
 
     Section 6.04 Other Liabilities and Obligations. As of the Merger Effective
Date, Spinco shall assume and be solely responsible for all Liabilities of NSU
with respect to claims made by persons who were, prior to the Merger Effective
Date, employees of NSU, relating to any employee liability or obligation not
otherwise provided for in this Agreement.
 
     Section 6.05 Preservation of Rights To Amend or Terminate Plans. No
provisions of this Agreement shall be construed as a limitation on the right of
Spinco or any Spinco Subsidiary to amend such plan or terminate its
participation therein which Spinco or any Spinco Subsidiary would otherwise have
under the terms of such plan or otherwise, and no provision of this Agreement
shall be construed to create a right in any employee or beneficiary of such
employee under a plan which such employee or beneficiary would not otherwise
have under the terms of the plan itself.

                                  TAX MATTERS
 
     Section 7.01 Allocation of Items of Income or Deduction for Reporting
Purposes. NSU, in consultation with and subject to the approval of Spinco, shall
either (i) cause Spinco to close its permanent books and records (including work
papers) as of the Distribution Date, in accordance with Treasury Regulations
Section 1.1502-76(b)(2) in order to permit Spinco's taxable income for the
taxable period ending on the Distribution Date to be reported and determined on
the basis of income shown on its permanent books and records (including work
papers) or (ii) allocate items of income or deduction between tax periods ending
on or before the Distribution Date and tax periods beginning after the
Distribution Date in accordance with Treasury Regulations Section
1.1502-76(b)(2)(ii).
 
     Section 7.02 Spinco Indemnification for Tax Periods Prior to Distribution
Date. Spinco agrees to indemnify and hold harmless NSU from and against any
liability for Taxes attributable to NSU or Spinco
 
                                      C-12
<PAGE>   154
 
(specifically including for all purposes of this Article VII, Taxes attributable
to all NSU Transferred Assets and NSU Transferred Liabilities transferred
pursuant to Article II) for Tax periods or portions thereof ending on or before
the Distribution Date. For purposes of this Section 7.02, "Spinco" shall mean
Spinco, itself, as well as all of its Subsidiaries eligible to be included in a
consolidated federal income tax return filed by Spinco as the common parent,
including any Subsidiary owned by NSU prior to the Merger Effective Date but not
then owned by NSU, and "NSU" shall mean NSU, itself, as well as all of its
Subsidiaries eligible to be included in a consolidated federal income tax return
filed by NSU as the common parent.
 
     Section 7.03 NSU Liable for Filing and Payment of Spinco's Taxes Prior to
Distribution Date. NSU, in consultation with and subject to the approval of
Spinco, shall, at Spinco's expense, file (or shall cause to be filed) all tax
returns of Spinco for tax periods ending on or before the Distribution Date. NSU
shall, to the extent permissible, include (or cause to be included) the results
of the operations of Spinco in NSU's consolidated federal tax return and in any
other consolidated, unitary, or combined tax return for tax periods ending on or
before the Distribution Date and shall, subject to the indemnification
obligations under Section 7.02, pay all Taxes due for such periods with respect
to Spinco.
 
     Section 7.04 Spinco Liable for Filing and Payment of Its Own Taxes for Tax
Periods Beginning Prior to Distribution Date and Ending After Distribution
Date. Spinco shall file (or shall cause to be filed) all Tax returns of Spinco
for any Tax period which begins before the Distribution Date and ends on or
after the Distribution Date. Spinco shall also file (or shall cause to be filed)
all Tax returns of Spinco for all subsequent Tax periods. Accordingly, Spinco
shall pay all Taxes shown as due on such returns or ultimately determined to be
due with respect to such periods and shall be entitled to keep and retain for
itself any refunds of Taxes or credits paid on behalf of or made available to
it. All Tax returns and any schedules to be included therewith for the Tax
period which begins before the Distribution Date and ends after the Distribution
Date shall be prepared on a basis consistent with those prepared for prior Tax
periods and consistent with the method used by NSU to allocate items of Spinco's
income or deduction for the Tax period ending on the Distribution Date pursuant
to Section 7.01 hereof, and shall be subject to the approval of NSU prior to
being filed by Spinco, which approval shall not be unreasonably withheld.
 
     Section 7.05 Spinco's Right to Make Section 172(b)(3) Election and
Qualified Right to Subsequent Refund. Spinco shall have the right and option to
make an election pursuant to Section 172(b)(3) of the Code to carry forward any
of its net operating losses incurred in tax periods beginning after the
Distribution Date which, if carried back, would be carried back to a tax period
ending on or before the Distribution Date. Notwithstanding the foregoing,
whether or not Spinco makes such an election, Spinco shall be entitled to any
and all tax refunds, whether received by NSU or Spinco, that result from a
carryback of net operating losses or credits of Spinco arising in a tax period
beginning after the Distribution Date to a tax period ending on or before the
Distribution Date.
 
     Section 7.06 Scope of NSU's Power to Negotiate Settlement During Audit for
Periods after the Merger Effective Date. In the event that any Taxing authority
conducts an audit to determine the amount of any net operating loss
carryforwards of NSU as of the Merger Effective Date for any Tax period
beginning after the Distribution Date, NSU shall notify Spinco and allow Spinco
to participate with NSU in contesting such issue and each party shall pay its
own expenses relating to the contesting of such issue. Notwithstanding the
foregoing, NSU shall have the right to finally resolve such issue.
 
     Section 7.07 Rights of Parties With Respect to an Asserted Tax
Liability. Promptly after receipt by NSU of a written notice of any demand,
claim or circumstance, including any Tax audit, which, after the lapse of time,
would or might give rise to a claim or commencement of any action, proceeding,
or investigation with respect to which indemnity may be sought under Section
7.02 hereof (an "Asserted Tax Liability"), NSU shall give written notice thereof
to Spinco (the "Tax Claim Notice"). The Tax Claim Notice shall contain factual
information (to the extent known to NSU) describing in reasonable detail the
Asserted Tax Liability and shall include copies of any notice or other document
received from any taxing authority in respect of such Asserted Tax Liability. If
NSU fails to give Spinco prompt notice of an Asserted Tax Liability as required
by this Section 7.07, and if such failure results in an irrevocable financial
detriment to Spinco, then any amount which Spinco is otherwise required to pay
NSU pursuant to Section 7.02 hereof with respect to such Asserted
 
                                      C-13
<PAGE>   155
 
Tax Liability shall be reduced by the amount of such irrevocable financial
detriment. Spinco may elect to direct, through counsel of its own choosing
reasonably acceptable to NSU and at its own expense, the compromise or contest,
either administratively or in the courts, of any Asserted Tax Liability. If
Spinco elects to direct the compromise or contest of any Asserted Tax Liability,
it shall, either within 30 calendar days after receiving the Tax Claim Notice
with respect to such Asserted Tax Liability (or sooner, if the nature of the
Asserted Tax Liability so requires) notify NSU of its intent to do so, and NSU
shall cooperate at its own expense in the compromise or contest of such Asserted
Tax Liability. Spinco, at its discretion, may enter into a settlement agreement
with respect to, or otherwise resolve, any Asserted Tax Liability without the
express consent of NSU, unless such settlement affects the Tax returns of NSU
after the Merger Effective Date, in which case the consent of NSU shall be
required and shall not be unreasonably withheld. If Spinco (1) within 30
calendar days after receiving the Tax Claim Notice with respect to such Asserted
Tax Liability (or sooner, if the nature of the Asserted Tax Liability so
requires) notifies NSU that it has elected not to direct the compromise or
contest of the Asserted Tax Liability, or (2) fails to properly notify NSU
within such period of its election to direct or not to direct the compromise or
contest of the Asserted Tax Liability, NSU may pay, compromise, or contest at
its own expense and in its sole discretion such Asserted Tax Liability. If NSU
or Spinco elects to direct the compromise or contest of any liability for Taxes
as provided herein, the other party shall promptly empower (by power of attorney
and such other documentation as may be appropriate) such representative of the
empowered party as the empowered party may designate to represent the empowering
party in any audit, claim for refund or administrative or judicial proceeding
insofar as such audit, claim for refund or proceeding involves an asserted
liability for Taxes for which Spinco would be liable under Section 7.02 hereof.
For all purposes of this Section 7.07, the right to participate in all
proceedings either administratively or in the courts relating to an Asserted Tax
Liability shall include the right to attend and be kept fully informed of all of
the foregoing but shall not include, unless expressly provided for herein, the
power to compromise, contest or make any other decisions with respect to an
Asserted Tax Liability.
 
     Section 7.08 Mutual Duty to Cooperate and Act in Good Faith With Respect to
Filing or Amending of Returns, Claiming Refunds, or Conducting Audit. NSU and
Spinco shall provide each other with such cooperation and information as either
reasonably may request of the other in filing any tax return, amended return, or
claim for refund, in determining a liability for Taxes or a right to a refund of
Taxes, or in conducting any audit or proceeding in respect of Taxes. Such
cooperation and information shall include providing copies of relevant tax
returns or portions thereof, together with accompanying schedules and related
work papers and documents relating to rulings or other determinations by tax
authorities. Each party shall make its employees available on a mutually
convenient basis to provide explanation of any documents or information provided
hereunder. NSU shall make available to Spinco, with respect to all tax years in
which Spinco was includable in NSU's affiliated group (as defined in Section
1504 of the Code) copies of all work papers and schedules relating to the
preparation of Spinco's pro forma federal and state income tax returns which
were included in NSU's federal consolidated and state income tax returns which
are necessary to reconcile such pro forma returns with the amounts actually
included in such consolidated returns. NSU and Spinco shall make available to
each other all other books and records relating to Taxes of Spinco with respect
to all tax years in which Spinco was includable in NSU's affiliated group (as
defined in Section 1504 of the Code). NSU and Spinco agree to maintain and
preserve for a period of eight (8) years after the period to which such
documents relate, and, upon written request, to provide to the other party, such
factual information as that party reasonably requires for filing tax returns,
tax planning, and contesting any tax audit that only NSU or Spinco, as the case
may be, actually possesses.

request. Within five days of receipt of the list, the parties shall

attorneys' fees and costs incurred in any such proceeding.

repeal of this section shall apply to or have any effect on the liability or
alleged liability of any director of the corporation for or with respect to acts

                         REGISTRATION RIGHTS AGREEMENT
 
             ORDERLY DISPOSITION AND REGISTRATION RIGHTS AGREEMENT
 
     This Agreement made and entered into this      day of December, 1995, by
and between NORTH STAR UNIVERSAL, INC., a Minnesota corporation, which, upon the
effective date of the Merger defined in the first recital hereof, will be the
parent corporation to the surviving corporation resulting from the merger of
Merger Sub and Michael as described in the first recital hereof ("Michael
Minnesota)", and 4J2R1C, a Minnesota limited partnership, 3J2R, a Minnesota
limited partnership, JAMES H. MICHAEL and JEFFREY J. MICHAEL (such individuals
and partnerships, together with any immediate family members of such individuals
or any corporation, partnership of trust in which such individuals or their
immediate family members are the sole shareholders, partners or beneficiaries
thereof, to be hereinafter collectively referred to as the "Michael
Shareholders").
 
     WITNESSETH:
 
     WHEREAS, Michael Minnesota is a party to an Agreement and Plan of
Reorganization dated December   , 1995 (the "Merger Agreement") providing for
the merger (the "Merger") of NSU Merger Co. ("Merger Sub"), a newly formed
Delaware corporation and wholly-owned subsidiary of Michael Minnesota, with and
into Michael Foods, Inc., a Delaware corporation ("Michael"), as the surviving
corporation; and
 
     WHEREAS, under Section 6.16 of the Merger Agreement, Michael Minnesota
agreed to execute and deliver and to cause the Michael Shareholders to execute
and deliver this Orderly Disposition and Registration Rights Agreement.
 
     NOW THEREFORE, IN CONSIDERATION of the premises and of the terms and
conditions hereinafter set forth, the parties agree as follows:
 
     1. Definitions. Unless the context otherwise requires or unless otherwise
defined in this agreement, capitalized terms shall have the meanings ascribed to
them in the Merger Agreement. Any references to Michael Minnesota shall include
North Star Universal, Inc. and Michael Minnesota from and after the consummation
of the Merger and the change of its name to Michael Foods, Inc.
 
     2. Actions Pending Effective Time. From the date of this Agreement until
the Effective Time, the Michael Shareholders, individually and collectively,
shall:
 
     a. not sell or offer to sell, hypothecate or transfer any shares of Michael
Minnesota common stock, except that this limitation shall not apply to sales of
Michael Minnesota common stock made pursuant to Rule 144 of the Securities and
Exchange Commission (the "SEC"), or the pledge of Michael Minnesota common stock
to secure surety bonds for Michael-Curry Companies, Inc. or transfers of Michael
Minnesota common stock among Michael Shareholders;
 
     b. vote in favor of the Merger, the Spinoff, the Reverse Stock Split and
the election of directors nominated by Michael Minnesota management at any
meeting of shareholders duly called and held for such purposes; and
 
     c. prepare and file any pre-merger notification to the Federal Trade
Commission required in connection with the Merger under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976 and the rules of the Federal Trade Commission
thereunder.
 
     3. Restrictions Upon Disposition. For a period of twenty-four (24) months
following the Effective Date, the Michael Shareholders, individually or
collectively, shall not:
 
     a. sell or offer to sell shares of common stock of Michael Minnesota
exceeding five percent (5%) of the then outstanding shares of common stock of
Michael Minnesota to any person or group in any single
<PAGE>   166
 
transaction or series of transactions without providing to Michael Minnesota the
first right to buy such shares as provided in Section 5 below;
 
     b. sell or offer to sell any shares of common stock of Michael Minnesota to
any person or group which owns five percent (5%) or more of the outstanding
common stock of Michael Minnesota without providing to Michael Minnesota the
first right to buy such shares as provided in Section 5 below; or
 
     c. pledge, hypothecate, or encumber any shares of Michael Minnesota owned
by any of the Michael Shareholders except to secure surety bonds obtained by
Michael-Curry Companies, Inc.
 
For purposes of this agreement, the term "group" shall mean any two or more
persons who agree to act together for the purpose of acquiring, holding, voting
or disposing of common stock of Michael Minnesota.
 
     4. Shares Covered. This agreement shall apply to all shares of common stock
of Michael Minnesota which are owned by the Michael Shareholders at the date of
this agreement or which are acquired by the Michael Shareholders prior to the
Effective Date or as a result of the Merger, but shall not apply to any shares
of common stock of Michael Minnesota which are purchased or otherwise acquired
by any of the Michael Shareholders subsequent to the Effective Date unless such
shares were subject to this agreement at the time they were so acquired by a
Michael Shareholder.
 
     5. Option to Purchase. Upon the occurrence of any of the events described
in Section 3(a) or (b), the Michael Shareholders or Shareholder proposing to
sell or offer shares of common stock of Michael Minnesota shall provide written
notice thereof to Michael Minnesota and shall offer to Michael Minnesota the
right to purchase such shares. The notice shall state the number of shares
offered and the price per share and any other conditions of the proposed sale or
offer and shall include a copy of any written document setting forth the terms
of the proposed sale or offer between the Michael Shareholders and the purchaser
or offeree. Michael Minnesota shall have twenty (20) days from its receipt of
such notice within which to purchase the shares so offered. In the event Michael
Minnesota does not complete the purchase within such twenty (20) day period, the
Michael Shareholders or Shareholder sending the notice shall be permitted for a
period of thirty (30) days thereafter to sell Michael Minnesota shares equal in
number to the shares offered in such notice free of any restrictions of this
agreement at a price no less than the purchase price per share set forth in such
notice and under terms and conditions no more favorable to the purchaser than
the terms and conditions offered to Michael Minnesota in such notice.
 
     6. Tender Offer. The restrictions set forth in Section 3 and the option to
purchase granted to Michael Minnesota in Section 5 shall not apply if a tender
offer is made for all or substantially all of the outstanding Michael Minnesota
common stock and the management of Michael Minnesota does not, within seven (7)
days of the commencement of such tender offer, announce its opposition to the
tender offer. Notwithstanding the foregoing, the following additional terms and
conditions shall apply in the event of a tender offer:
 
     a. In the event that one or more of the Michael Shareholders has offered
shares to Michael Minnesota pursuant to Section 5 hereof and, prior to
acceptance of such offer by Michael Minnesota, a tender offer is made for all or
substantially all of the outstanding Michael Minnesota common stock, Michael
Minnesota shall, within twenty (20) days of the date such Michael Shareholder(s)
have made such offer, have the right to acquire the shares offered by such
Michael Shareholder(s) at the higher of the price offered by the Michael
Shareholder(s) or the tender offer price, regardless of whether Michael
Minnesota's management has announced it opposition to such tender offer.
 
     b. In the event that one or more of the Michael Shareholders has offered
shares to Michael Minnesota pursuant to Section 5 hereof and, following
acceptance of such offer by Michael Minnesota but prior to the closing of such
transaction, either a tender offer is made for all or substantially all of the
outstanding Michael Minnesota common stock or the management of Michael
Minnesota rescinds an earlier opposition to such a tender offer, Michael
Minnesota shall have the option of (a) rescinding its agreement to purchase the
shares from such Michael Shareholder(s) within two (2) days of the commencement
of such tender offer or its announcement of its rescindment of its opposition to
the tender offer; or (b) acquiring such shares at the higher of the price
offered by such Michael Shareholder(s) at the tender offer price.

<PAGE>   167
 
     7. Legend. Each of the Michael Shareholders shall forthwith deliver to the
secretary of Michael Minnesota all certificates representing shares of common
stock of Michael Minnesota which are subject to this agreement for the purpose
of placing thereon the following legend:
 
     "The shares represented by this certificate are subject to certain
     restrictions on the transfer, sale or other disposition of the shares
     pursuant to an agreement dated             , 1995 between the issuer and
     the registered owner hereof, a copy of which may be obtained from the
     secretary of the corporation."
 
The secretary shall promptly return the legended certificates to the Michael
Shareholders.
 
     8. Directors. For a period of twenty-four (24) months following the
Effective Date, the Board of Directors of Michael Minnesota shall include
representatives of the Michael Shareholders as provided below. The first board
of directors of Michael Minnesota at the Effective Date shall include Jeffrey J.
Michael and Miles E. Efron or other substitute nominees of the Michael
Shareholders if either of them are unable or unwilling to serve as
representatives of the Michael Shareholders. Within thirty (30) days following
the end of each calendar year after the Effective Date and within the
twenty-four (24) months following the Effective Date, the Michael Shareholders
shall give notice to Michael Minnesota of their nominee or nominees for Board of
Directors. If the Michael Shareholders collectively own 10% or more of the
outstanding common stock of Michael Minnesota, they shall be entitled to
nominate two (2) directors. If the Michael Shareholders own less than 10% of the
outstanding common stock of Michael Minnesota, they shall be entitled to
nominate one (1) director. Notice hereunder shall be given by Jeffrey J.
Michael, as representative of all the Michael Shareholders.
 
     9. Registration Rights.
 
     a. Piggyback Rights. If at any time within twenty-four (24) months
following the Effective Date, Michael Minnesota proposes to register common
stock under the Securities Act of 1933, as amended (the "Securities Act") in
connection with a public offering of common stock for its own account solely for
cash (other than a registration on form S-4 or S-8 or any successor form
thereof) in a manner that would permit registration of all or a portion of the
Michael Minnesota common stock owned by the Michael Shareholders, it will give
prompt notice thereof to the Michael Shareholders. Upon written notice of any
Michael Shareholders to Michael Minnesota received within fifteen (15) days
after delivery of notice of the proposed offering by Michael Minnesota, Michael
Minnesota will use its best efforts to effect the registration of the Michael
Minnesota shares covered by such notice under the Securities Act; provided,
however, that Michael Minnesota shall have the right to abandon the registration
in its entirety at any time and shall not be required to register shares of the
Michael Shareholders if the underwriters in any underwritten offering reasonably
object to the inclusion of such shares in the registration, and provided
further, that in any underwritten offering, the Michael Shareholders
participating in the registration agree to sell their shares to the underwriters
on the same terms and conditions as apply to Michael Minnesota, with such
differences as customarily apply in combined primary and secondary offerings.
 
     b. Requested Registration. If, at any time commencing on the Effective Date
and continuing for a period of twenty-four (24) months thereafter, Michael
Minnesota shall receive a written request from one or more Michael Shareholders
that Michael Minnesota effect the registration under the Securities Act of all
or a part of such Michael Shareholder's(') shares of Michael Minnesota common
stock constituting in the aggregate at least 500,000 shares (such number of
shares to be adjusted to reflect any stock split, stock dividend or other
combination or reclassification of Michael Minnesota's capital stock after the
Effective Date) and requesting that such shares be sold in a registered public
offering in accordance with this Section 9, then Michael Minnesota will, within
ten (10) days after receipt thereof, give notice to all other Michael
Shareholders of the receipt of such request and each such holder may elect by
written notice received by Michael Minnesota within ten (10) days from the date
of the notice by Michael Foods to have all or part of his shares of Michael
Minnesota common stock included in such registration; provided, however, that
the Michael Shareholders collectively shall only have the right to cause Michael
Minnesota to effect a registration pursuant to this section on two occasions
during such twenty-four (24) month period. Upon receipt of such notice, Michael
Minnesota will, as soon as practicable, use reasonable efforts to effect the
registration under the Securities Act of all registrable securities which it has
been so requested to register and provided further, that Michael
 
                                       E-3
<PAGE>   168
 
Minnesota: (i) shall not be obligated to cause any special audit to be
undertaken in connection with any such registration; (ii) shall be entitled to
postpone for a reasonable period of time, but not in excess of one hundred
twenty (120) days, the filing of any registration statement otherwise required
to be prepared pursuant to this section if Michael Minnesota is, at such time,
conducting or about to conduct an underwritten public offering of equity
securities (or securities convertible into equity securities) and is advised in
writing by its managing underwriter that such offer would, in its opinion, be
adversely effected by the registration so requested; and (iii) shall be entitled
to postpone such requested registration for up to 120 days if Michael Minnesota
determines, in view of the advisability of deferring public disclosure of
material corporate developments or other information, that such registration and
the disclosure required to be made pursuant thereto would not be in the best
interest of Michael Minnesota at such time.
 
     c. Form of Requested Registration. All registrations proposed to be
effected under this Section shall be made on Form S-3 unless the registration
shall be in connection with underwritten public offering and the managing
underwriter shall advise Michael Minnesota in writing that, in its opinion, the
use of another form of registration statement is of material importance to the
success of such proposed offering. In such case, the registration shall be
effected on such other form. During the term of this agreement, Michael
Minnesota shall take all such reasonable actions as may be necessary to maintain
its eligibility to use such form(s).
 
     d. Expenses. In connection with any registration statement pursuant to this
section and whether or not the sale of the shares is consummated, each selling
Michael Shareholder will pay: (i) a pro rata portion of the aggregate
registration expenses and other expenses incurred by Michael Minnesota in
connection with the registration of the sale of the shares and the sale of the
shares offered based on the number of such Michael Shareholder's(') registrable
securities included in the registration statement at the time the registration
statement is filed with the SEC relative to the total number of securities
covered by such registration statement at such time, (ii) a pro rata portion
(based on the number of such Michael Shareholder's registrable securities
included in the registration statement at the time the registration statement is
filed with the SEC relative to the total number of securities covered by such
registration statement at such time) of the aggregate fees and disbursements of
underwriters customarily paid by issuers or sellers of securities, including
liability insurance if Michael Minnesota so desires or if the underwriters so
require, and the reasonable fees and expenses of any special experts retained in
connection with the requested registration; (iii) the fees and disbursements of
counsel to Michael Shareholder(s); and (iv) all underwriting discounts and
commissions and transfer taxes, if any, applicable to shares of registrable
securities to be sold on behalf of Michael Shareholder(s). All such amounts
shall be due and payable at the request of Michael Minnesota at the closing of
any underwritten offering, the effective date of the registration statement in
the case of a non-underwritten offering or upon abandonment of the registration.
 
     e. Completion. A registration requested pursuant to this section will not
be deemed to have been effected unless it has become effective under the
Securities Act, provided that, if within 180 days after it has become effective
the offering of registrable securities pursuant to such registration is
interfered with by any stop order, injunction or other order or requirement of
the SEC or other governmental agency or court, such registration will be deemed
not to have been effected.
 
     f. Selection of Underwriter and Investment Manager. If a requested
registration pursuant to this section involves an underwritten offering, Michael
Minnesota shall have the exclusive right to select an investment banker or
bankers and managers to administer the offering. The offer or sale of Michael
Minnesota shares to an underwriter in a registered public offering shall not
constitute a sale or offer to sell the shares for purposes of Section 3(a) or
3(b).
 
     g. Registration. If and whenever Michael Minnesota is required to use its
reasonable efforts to cause the registration of any registrable securities under
the Securities Act as provided in this agreement, Michael Minnesota will, as
expeditiously as reasonably possible: (i) prepare and file with the SEC a
registration statement with respect to such registrable securities and use its
best efforts to cause such registration statement to become effective and, upon
the request of the holders of a majority of the registrable securities
registered by the Michael Shareholder(s) hereunder, keep such registration
statement effective for one hundred eighty (180) days; (ii) prepare and file
with the SEC such amendments and supplements to such
 
                                       E-4
<PAGE>   169
 
registration statement and the prospectus used in connection therewith as may be
necessary to comply with the provisions of the Securities Act with respect to
the disposition of all securities covered by such registration statement; (iii)
furnish to each Michael Shareholder seeking registration hereunder such number
of copies of the prospectus included in such registration statement (including
each preliminary prospectus and summary prospectus), and such other documents as
each such Michael Shareholder may reasonably request in order to facilitate the
disposition of the registrable securities by such seller but only while it shall
be required under the provisions hereof to cause the registration statement to
remain current; (iv) use its reasonable efforts to register or qualify such
registrable securities covered by such registration statement under such other
securities or blue sky laws of such jurisdictions as the sellers shall
reasonably request, except that Michael Minnesota shall not, for any purpose, be
required to qualify generally to do business as a foreign corporation in any
jurisdiction where, but for the requirements of this clause, it would not be
obligated to be so qualified, to subject itself to taxation in any such
jurisdiction, or consent to general service of process in any such jurisdiction;
(v) use its reasonable efforts to list the securities being registered on the
National Association of Securities Dealers, Inc. National Market System
("NASDAQ-NMS"), if such registrable securities are not already so listed.
 
     h. Information. Michael Minnesota may require each selling Michael
Shareholder to furnish it with such information regarding such selling Michael
Shareholder and pertinent to the disclosure requirements relating to the
registration and the distribution of such securities as Michael Minnesota may
from time to time reasonably request in writing.
 
     i. Underwriting Agreement. The selling Michael Shareholders shall execute
and deliver an underwriting agreement in customary form in connection with any
underwritten offering made pursuant to a registration hereunder.
 
     10. Indemnification and Contribution. As a condition to the registration of
registrable securities of the Michael Shareholders pursuant to this agreement,
Michael Minnesota may require the selling Michael Shareholders to enter into an
Indemnification and Contribution Agreement with respect to claims or liabilities
arising under the Securities Act or the Securities Exchange Act of 1934 as a
result of the representations and warranties made by the selling Michael
Shareholder(s) in connection with their offer or sale of the registrable
securities. Such agreement shall be in customary form and shall contain mutual
cross indemnity and contribution provisions.
 
     11. General Provisions.
 
     a. Governing Law. This agreement shall be governed by and interpreted and
enforced in accordance with the laws of the State of Minnesota without giving
effect to any conflicts of law provisions.
 
     b. Remedies. Michael Minnesota, on the one hand, and the Michael
Shareholders, on the other, acknowledges and agrees that the other would not
have an adequate remedy at law for money damages in the event that any of the
covenants or agreements in this agreement of such party were not performed in
accordance with its terms, and it is therefore agreed that in addition to and
without limiting any other remedy or right such party may have, any party will
have the right to an injunction or other equitable relief (including specific
performance) in any court of competent jurisdiction, enjoining any such breach
and enforcing specifically the terms and provisions hereof. All rights, powers
and remedies provided under this agreement or otherwise available in respect
hereof at law or in equity shall be cumulative and not alternative.
Notwithstanding the foregoing, Michael Minnesota hereby acknowledges and agrees
that, from the date hereof until and including the Effective Date, it shall not
be entitled hereunder to any claim for money damages against the Michael
Shareholder, it being the intention of the parties hereto that any claim for
damages arising out of a failure of the Merger to become effective shall be
limited to the damages specified in Section 8.2(a) of the Merger Agreement,
which such damages shall be payable by North Star Universal, Inc., a Minnesota
corporation which is a constituent party to the proposed Merger.
 
     c. Notices. All notices, demands, requests, certificates or other
communications under this Agreement and all legal processes in regard hereto
shall be in writing and shall be decreed to be validly given, made or served
when delivered personally or deposited in the U.S. mail, postage prepaid, for
delivery by express,

     d. Severability. If any term, provision, covenant or restriction of this
agreement is held by a court of competent jurisdiction to be invalid, void, or
unenforceable, the remainder of the terms, provisions, covenants and
restrictions shall remain in full force and effect and shall in no way be
affected, impaired or invalidated. The parties agree that they will use their
best efforts at all times to support and defend this agreement.

writing signed by all of the parties hereto.

     g. Counterparts. This agreement shall become binding when one or more
counterparts hereof, individually or taken together, bears the signatures of
each of the parties hereto. This agreement may be executed in any number of
counterparts, each of which shall be an original as against the party whose
signature appears thereon, or on whose behalf such counterpart is executed, but
all of which when taken together shall be one and the same statement.
 
     h. Successors and Assigns. This agreement shall be binding upon and inure
to the benefit of and be enforceable by the successors and assigns of the
parties hereto, provided that a Michael Shareholder may not assign any of his
rights or obligations hereunder to any person without the prior written consent
of Michael Minnesota. Notwithstanding the foregoing, the consent of Michael
Minnesota shall not be required in connection with the assignment of this
agreement to the estate of a Michael Shareholder.

Board of Directors
Michael Foods, Inc.
324 Park National Bank Building
5353 Wayzata Boulevard
Minneapolis, MN 55416
 
Members of the Board:
 
     This letter relates to the proposed merger of Michael Foods, Inc. ("Michael
Foods") and a newly formed merger subsidiary ("Merger Sub") of North Star
Universal, Inc. ("NSU") (the "Merger") pursuant to the Agreement and Plan of
Reorganization by and between Michael Foods, NSU and Merger Sub (the
"Agreement"). Prior to the Merger, NSU will transfer to a subsidiary ("Spinco")
all assets (other than its shares of Michael Foods and other mutually agreed
assets) and liabilities (other than $25 to $38 million of net debt (the "Debt"))
of NSU and will then spin off the shares of Spinco on a pro rata basis to the
NSU shareholders before the Merger. In connection with the Merger, NSU
shareholders will receive their pro rata share of Michael Foods stock owned by
NSU before the Merger after a portion of those shares are repurchased by Michael
Foods. The amount of shares repurchased will be equal to the amount of Debt
assumed by Michael Foods in the Merger divided by the product of the Discount
Factor (as defined in the Agreement) times the average price of Michael Foods
common stock during the twenty trading days ending the third trading day
immediately preceding the effective date of the Merger. It is our understanding,
and for purposes of this opinion we have assumed, that the Debt shall not be
less than $25,000,000 nor more than $38,000,000 and that NSU will have no
liabilities following the Merger other than liabilities assumed from Michael
Foods, the NSU Retained Liabilities (as defined in the Agreement) and
liabilities which are fully indemnified against by Spinco. In connection with
the Merger, all shares of Michael Foods common stock held by shareholders other
than NSU will be exchanged for NSU common stock. You have requested our opinion
as to the fairness to Michael Foods, from a financial point of view, of the
effective price per share that Michael Foods is paying NSU in the form of Debt
assumed (the "Consideration") for the shares of Michael Foods common stock that
it is repurchasing from NSU, and the exchange of Michael Foods common stock for
NSU common stock.
 
     Piper Jaffray Inc. ("Piper Jaffray"), as a customary part of its investment
banking business, is engaged in the valuation of businesses and their securities
in connection with mergers and acquisitions, underwritings and secondary
distributions of securities, private placements, and valuations for estate,
corporate and other purposes. Piper Jaffray makes a market in the Common Stock
of Michael Foods and also provides research coverage for Michael Foods. We acted
as comanager of public offerings of Michael Foods common stock in 1987, 1988 and
1991 and an offering of senior notes in 1989. For our services in rendering this
opinion, Michael Foods will pay us a fee and indemnify us against certain
liabilities. The fee is not contingent upon the consummation of the Merger.
 
     In arriving at our opinion, we have undertaken such reviews, analyses and
inquiries as we deemed necessary and appropriate under the circumstances. Among
other things, we have:
 
          1. Reviewed the Agreement and Plan of Reorganization by and between
     Michael Foods, NSU and Merger Sub dated December 21, 1995.
 
          2. Reviewed the annual reports, Form 10-K's and audited financial
     statements for Michael Foods for the three years ended December 31, 1994.
 
          3. Reviewed the Form 10-Q's for Michael Foods for the quarters ended
     March 31, June 30 and September 30, 1995.

          4. Reviewed the annual reports, Form 10-K's and audited financial
     statements for NSU for the three years ended December 31, 1994.
 
        5. Reviewed the Form 10-Q's for NSU for the quarters ended March 31,
     June 30 and September 30, 1995.
 
        6. Reviewed two-year financial forecasts for Michael Foods furnished by
     Michael Foods management.
 
          7. Conducted discussions with members of senior management of Michael
     Foods, including the President and Chief Executive Officer, Chief Financial
     Officer and Executive Vice President and Assistant Treasurer. Topics
     discussed included, but were not limited to, the background and rationale
     for the proposed Merger, the financial condition, operating performance,
     balance sheet characteristics and prospects of Michael Foods business
     independently and the financial and operating prospects for the combined
     company after consummation of the proposed Merger.
 
          8. Conducted discussions with members of senior management of NSU,
     including the Chief Financial Officer. Topics discussed included, but were
     not limited to, the background and rationale of the proposed Merger, the
     financial condition, operating performance, and the balance sheet
     characteristics of NSU and the prospects for the combined company after
     consummation of the proposed Merger.
 
        9. Reviewed the historical prices and trading activity for Michael Foods
     common stock and NSU common stock.
 
          10. Reviewed the financial terms, to the extent publicly available, of
     certain comparable transactions which we deemed relevant.
 
          11. Considered the proforma effect of the proposed Merger on Michael
     Foods earnings per share for the two fiscal years ending December 31, 1997.
 
          12. Compared certain financial and securities data of Michael Foods
     with certain financial and securities data of companies deemed similar to
     Michael Foods or representative of the business sector in which Michael
     Foods operates.
 
          13. Reviewed such other financial data, performed such other analyses
     and considered such other information as we deemed necessary and
     appropriate under the circumstances.
 
     We have relied upon and assumed the accuracy and completeness of the
financial statements and other information provided by Michael Foods, NSU or
otherwise made available to us and have not attempted independently to verify
such information. We have further relied upon the assurances of Michael Foods'
management that the information provided pertaining to Michael Foods has been
prepared on a reasonable basis and, with respect to financial planning data,
reflects the best currently available estimates and that they are not aware of
any information or facts that would make the information provided to us
incomplete or misleading. In that regard, we have assumed with your consent that
any projections or forecasts, reflect best currently available estimates and
judgments of the Michael Foods management, and that such projections and
forecasts will be realized in the amounts and in the time periods currently
estimated by the management of Michael Foods. For the purpose of this opinion,
we have assumed that neither Michael Foods nor NSU is a party to any pending
transaction, including external financing, recapitalizations, acquisitions or
merger discussions, other than the Merger or in the ordinary course of business.
We have also assumed, with your consent, that the Merger will qualify as a
tax-free exchange.
 
     In arriving at our opinion, we have not performed any appraisals or
valuations of specific assets of Michael Foods or NSU and express no opinion
regarding the liquidation value of Michael Foods or NSU. Our opinion is
necessarily based upon information available to us, facts and circumstances and
economic, market and other conditions as they exist and are subject to
evaluation on the date hereof; events occurring after the date hereof could
materially affect the assumptions used in preparing this opinion. We have not
undertaken to reaffirm or revise this opinion or otherwise comment upon any
events occurring after the date hereof. We
 
                                      II-2
<PAGE>   175
 
express no opinion herein as to the prices at which shares of Michael Foods
common stock may trade at any future time.
 
   
     This opinion shall not be published or otherwise used, nor shall any public
references to Piper Jaffray be made without our written consent, except for
inclusion in the full proxy/prospectus to be sent to all stockholders of Michael
Foods and NSU and in any filings or disclosures required by law. This opinion is
not intended to be and does not constitute a recommendation to any stockholder
as to how such stockholder should vote with respect to the Merger. In connection
with this opinion, we were not requested to opine as to, and this opinion does
not address, the merits of the basic business decision to proceed with or effect
the Merger.
    
 
     Based upon and subject to the foregoing and based upon such other factors
as we consider relevant, it is our opinion that the Consideration for the
repurchase of the Michael Foods common stock and the exchange of Michael Foods
common stock for NSU common stock is fair, from a financial point of view, to
Michael Foods.
 
Sincerely,

RE: Fairness Opinion
 
Gentlemen:
 
     In connection with the proposed transaction (the "Transaction"), consisting
of the Merger together with the Spin-off as defined below, whereby Michael
Foods, Inc. ("MFI") will merge (the "Merger") into a newly organized subsidiary
of North Star Universal, Inc. (the "Company"), immediately before the
distribution (the "Spin-off") to the Company's shareholders, as constituted
prior to the merger (the "Current Shareholders"), of all of the outstanding
shares of second newly organized subsidiary of the Company ("Spinco"), you have
requested our opinion ("Opinion") as to the fairness, from a financial point of
view, of the Transaction to the Company's Current Shareholders.
 
     As a customary part of its investment banking business, Goldsmith, Agio,
Helms Securities, Inc. ("GAHS") is engaged in the valuation of businesses and
securities in connection with mergers and acquisitions, private placements, and
valuations for estate, corporate, and other purposes. GAHS does not make a
market for the Company's common stock. GAHS is a party to a separate engagement
agreement with the Company whereby GAHS is providing advisory services to the
Company with respect to the Transaction, pursuant to which GAHS contingent on
consummation of the Transaction. In return for GAHS' services in connection with
providing this Opinion, the Company will pay GAHS a fee of $100,000, twenty-five
percent of which fee is not contingent upon the consummation of the Transaction,
with the balance payable to GAHS upon closing of the Transaction. In addition,
the Company will indemnify GAHS against certain liabilities.
 
     In arriving at our opinion, we have undertaken such reviews, analyses and
inquiries as we deemed necessary and appropriate under the circumstances. Among
other things, we have reviewed the Merger Agreement, the Distribution Agreement,
and financial and other information relating to the Company and MFI. We reviewed
the reported price and trading activity of the common stock of the Company and
of MFI. We compared certain financial and stock market information with respect
to the Company and MFI with similar information for certain other companies, the
securities of which are publicly traded. We have made inquiries of the Company's
management as to the Company's financial condition, operating results, business
outlook, plans and opportunities.
 
     We have relied upon and assume the accuracy, completeness, and fairness of
the financial statements and other information of the Company, and have not
attempted independently to verify such information. We have further relied upon
assurances by the Company that the information provided to us has a reasonable
basis, and with respect to projections and other business outlook information,
reflects the best currently available estimates, and that the Company is not
aware of any information or fact that would make the information provided to us
incomplete or misleading. Our Opinion is not based on any specific appraisal of
the liquidation value of the Company, or any of its assets, or of Spinco. We are
not expressing any Opinion as to the prices at which shares of common stock of
Spinco or the Company or MFI will trade subsequent to the date of the
Transaction, and we are not expressing any Opinion as to the prices at which
shares of the Company's or MFI's common stock have traded prior to the date of
the Transaction. Our Opinion is based upon the information available to us and
the facts and circumstances as they exist and are subject to evaluation on the
date hereof; events occurring after the date hereof could materially affect the
assumptions used in preparing this Opinion. We did not actively solicit
indications of interest or value from any third parties for the Company or any
of its assets, and we did not solicit indications of interest or value from any
third parties for MFI. We
 
                                      III-1
<PAGE>   178
 
were not requested to opine, and do not opine, in any way concerning other
transactions or agreements entered into in conjunction with the Transaction.
 
   
     Based upon and subject to the foregoing, and based upon such other facts as
we consider relevant, it is our opinion that, as of the date hereof, the
Transaction is fair to the Company's Current Shareholders from a financial point
of view.
    
 
                                        Sincerely,
 
                                        Goldsmith, Agio, Helms Securities Inc.

     SUBDIVISION 1. ACTIONS CREATING RIGHTS. A shareholder of a corporation may
dissent from, and obtain payment for the fair value of the shareholder's shares
in the event of, any of the following corporate actions:
 
     (a) An amendment of the articles that materially and adversely affects the
rights or preferences of the shares of the dissenting shareholder in that it:
 
          (1) alters or abolishes a preferential right of the shares;
 
          (2) creates, alters, or abolishes a right in respect of the redemption
     of the shares, including a provision respecting a sinking fund for the
     redemption or repurchase of the shares;
 
          (3) alters or abolishes a preemptive right of the holder of the shares
     to acquire shares, securities other than shares, or rights to purchase
     shares or securities other than shares;
 
          (4) excludes or limits the right of a shareholder to vote on a matter,
     or to cumulate votes, except as the right may be excluded or limited
     through the authorization or issuance of securities of an existing or new
     class or series with similar or different voting rights; except that an
     amendment to the articles of an issuing public corporation that provides
     that section 302A.671 does not apply to a control share acquisition does
     not give rise to the right to obtain payment under this section;
 
     (b) A sale, lease, transfer, or other disposition of all or substantially
all of the property and assets of the corporation, but not including a
transaction permitted without shareholder approval in section 302A.661,
subdivision 1, or a disposition in dissolution described in section 302A.725,

their respective interests within one year after the date of disposition;
 
     (c) A plan of merger, whether under this chapter or under chapter 322B, to
which the corporation is a party, except as provided in subdivision 3;
 
     (d) A plan of exchange, whether under this chapter or under chapter 322B,
to which the corporation is a party as the corporation whose shares will be
acquired by the acquiring corporation, if the shares of the shareholder are
entitled to be voted on the plan; or
 
     (e) Any other corporate action taken pursuant to a shareholder vote with
respect to which the articles, the bylaws, or a resolution approved by the board
directs that dissenting shareholders may obtain payment for their shares.
 
     SUBD. 2. BENEFICIAL OWNERS. (a) A shareholder shall not assert dissenters'
rights as to less than all of the shares registered in the name of the
shareholder, unless the shareholder dissents with respect to all the shares that
are beneficially owned by another person but registered in the name of the
shareholder and discloses the name and address of each beneficial owner on whose
behalf the shareholder dissents. In that event, the rights of the dissenter
shall be determined as if the shares as to which the shareholder has dissented
and the other shares were registered in the names of different shareholders.
 
     (b) The beneficial owner of shares who is not the shareholder may assert
dissenters' rights with respect to shares held on behalf of the beneficial
owner, and shall be treated as a dissenting shareholder under the terms of this
section and section 302A.473, if the beneficial owner submits to the corporation
at the time of or before the assertion of the rights a written consent of the
shareholder.
 
     SUBD. 3. RIGHTS NOT TO APPLY. Unless the articles, the bylaws, or a
resolution approved by the board otherwise provide, the right to obtain payment
under this section does not apply to a shareholder of the surviving corporation
in a merger, if the shares of the shareholder are not entitled to be voted on
the merger.

rescinded, except when the corporate action is fraudulent with regard to the
complaining shareholder or the corporation.

intent to demand the fair value of the shares owned by the shareholder and must
not vote the shares in favor of the proposed action.
 
     SUBD. 4. NOTICE OF PROCEDURE; DEPOSIT OF SHARES.  (a) After the proposed

and to all shareholders entitled to dissent if no shareholder vote was required,
a notice that contains:
 
          (1) The address to which a demand for payment and certificates of
     certificated shares must be sent in order to obtain payment and the date by
     which they must be received;
 
          (2) Any restrictions on transfer of uncertificated shares that will
     apply after the demand for payment is received;
 
          (3) A form to be used to certify the date on which the shareholder, or
     the beneficial owner on whose behalf the shareholder dissents, acquired the
     shares or an interest in them and to demand payment; and
 
          (4) A copy of section 302A.471 and this section and a brief

rights of a shareholder until the proposed action takes effect.

          (1) The corporation's closing balance sheet and statement of income

<PAGE>   182
 
          (2) An estimate by the corporation of the fair value of the shares and
     a brief description of the method used to reach the estimate; and
 
          (3) A copy of section 302A.471 and this section, and a brief
     description of the procedure to be followed in demanding supplemental
     payment.
 
     (b) The corporation may withhold the remittance described in paragraph (a)
from a person who was not a shareholder on the date the action dissented from
was first announced to the public or who is dissenting on behalf of a person who
was not a beneficial owner on that date. If the dissenter has complied with
subdivisions 3 and 4, the corporation shall forward to the dissenter the
materials described in paragraph (a) a statement of the reason for withholding
the remittance, and an offer to pay to the dissenter the amount listed in the
materials if the dissenter agrees to accept that amount in full satisfaction.
The dissenter may decline the offer and demand payment under subdivision 6.
Failure to do so entitles the dissenter only to the amount offered. If the
dissenter makes demand, subdivisions 7 and 8 apply.
 
     (c) If the corporation fails to remit payment within 60 days of the deposit
of certificates or the imposition of transfer restrictions on uncertificated
shares, it shall return all deposited certificates and cancel all transfer
restrictions. However, the corporation may again give notice under subdivision 4
and require deposit or restrict transfer at a later time.
 
     SUBD. 6. SUPPLEMENTAL PAYMENT; DEMAND. If a dissenter believes that the
amount remitted under subdivision 5 is less than the fair value of the shares
plus interest, the dissenter may give written notice to the corporation of the
dissenter's own estimate of the fair value of the shares, plus interest, within
30 days after the corporation mails the remittance under subdivision 5, and
demand payment of the difference. Otherwise, a dissenter is entitled only to the
amount remitted by the corporation.
 
     SUBD. 7. PETITION; DETERMINATION. If the corporation receives a demand
under subdivision 6, it shall, within 60 days after receiving the demand, either
pay to the dissenter the amount demanded or agreed to by the dissenter after
discussion with the corporation or file in court a petition requesting that the
court determine the fair value of the shares, plus interest. The petition shall
be filed in the county in which the registered office of the corporation is
located, except that a surviving foreign corporation that receives a demand
relating to the shares of a constituent domestic corporation shall file the
petition in the county in this state in which the last registered office of the
constituent corporation was located. The petition shall name as parties all
dissenters who have demanded payment under subdivision 6 and who have not
reached agreement with the corporation. The corporation shall, after filing the
petition, serve all parties with a summons and copy of the petition under the
rules of 180 civil procedure. Nonresidents of this state may be served by
registered or certified mail or by publication as provided by law. Except as
otherwise provided, the rules of civil procedure apply to this proceeding. The
jurisdiction of the court is plenary and exclusive. The court may appoint
appraisers, with powers and authorities the court deems proper, to receive
evidence on and recommend the amount of the fair value of the shares. The court
shall determine whether the shareholder or shareholders in question have fully
complied with the requirements of this section, and shall determine the fair
value of the shares, taking into account any and all factors the court finds
relevant, computed by any method or combination of methods that the court, in
its discretion, sees fit to use, whether or not used by the corporation or by a
dissenter. The fair value of the shares as determined by the court is binding on
all shareholders, wherever located. A dissenter is entitled to judgment in cash
for the amount by which the fair value of the shares as determined by the court,
plus interest, exceeds the amount, if any, remitted under subdivision 5, but
shall not be liable to the corporation for the amount, if any, by which the
amount, if any, remitted to the dissenter under subdivision 5 exceeds the fair
value of the shares as determined by the court, plus interest.
 
     SUBD. 8. COSTS; FEES; EXPENSES. (a) The court shall determine the costs and
expenses of a proceeding under subdivision 7, including the reasonable expenses
and compensation of any appraisers appointed by the court, and shall assess
those costs and expenses against the corporation, except that the court may
assess part or all of those costs and expenses against a dissenter whose action
in demanding payment under subdivision 6 is found to be arbitrary, vexatious, or
not in good faith.

     (b) If the court finds that the corporation has failed to comply
substantially with this section, the court may assess all fees and expenses of
any experts or attorneys as the court deems equitable. These fees and expenses
may also be assessed against a person who has acted arbitrarily, vexatiously, or
not in good faith in bringing the proceeding, and may be awarded to a party
injured by those actions.
 
     (c) The court may award, in its discretion, fees and expenses to an
attorney for the dissenters out of the amount awarded to the dissenters, if any.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
 
NOTE 1 -- ORGANIZATION AND BUSINESS
 
     ENStar (the "Operating Unit" or the "Unit") is an Operating Unit of North
Star Universal, Inc. ("North Star"). The Operating Unit is comprised of
Americable, Inc. ("Americable"), Transition Networks, Inc., ("Transition") and
Eagle Engineering and Manufacturing, Inc. ("Eagle," which is included in net
assets held for sale), along with an equity investment in CorVel Corporation
("CorVel") and certain other assets. At December 31, 1995, North Star owned a
35% ownership interest in CorVel and following the sale of 350,000 shares in
January 1996, its ownership was reduced to 27%. The accompanying financial
statements reflect a 27% ownership interest for all periods presented. The
Operating Unit's investment in CorVel is accounted for as an unconsolidated
subsidiary using the equity method of accounting.
 
     Americable is a provider of connectivity and networking products and
services. Transition designs, manufactures and markets connectivity devices used
in network applications.
 
   
     Pursuant to the terms of an agreement between North Star and Michael Foods,
Inc. ("Michael Foods"), the net assets owned by the Unit will be transferred to
a newly formed corporation, ENStar Inc. Under the terms of the agreement, the
shares of ENStar Inc. will be declared payable in a tax free dividend to the
North Star shareholders of record prior to the effective date of such merger and
distributed immediately following the merger. The transaction is subject to the
receipt of a favorable ruling from the Internal Revenue Service that the
transactions are tax free to the shareholders of Michael Foods and North Star,
the approval of both companies shareholders and other closing conditions.
    
 
NOTE 2 -- SUMMARY OF ACCOUNTING POLICIES
 
     BASIS OF PRESENTATION The accompanying combined financial statements have
been prepared from the books and records of the entities and investments
described in Note 1. The combined financial statements include an allocation of
general and administrative costs incurred by North Star in the management of the
operating companies, investment holding and other assets of the Unit. Management
believes these allocations are reasonable and present the operations of the Unit
as though it was operated on a stand alone basis. Additionally, operating unit
equity includes the historical equity of each entity, other net assets
contributed to the Unit and intercompany payables owed to North Star. The annual
net advances between the Unit and North Star are considered additional capital
invested from, or constructive dividends to, North Star. Accordingly, the
accompanying combined financial statements may not necessarily be indicative of
the results that would have been obtained if the Unit had been operated as a
stand alone entity.
 
   
     Combined financial statements and related footnote data as of and for the
three months ended March 31, 1996 and 1995 are unaudited, but in the opinion of
management of the Unit, include all adjustments (consisting only of normal
recurring adjustments) necessary for fair presentation thereof. The results of
operations for the three months ended March 31, 1996 and 1995 are not
necessarily indicative of the results of a full year.
    
 
     PRINCIPLES OF COMBINATION Significant inter-unit balances and transactions
have been eliminated.
 
     CASH AND CASH EQUIVALENTS The Unit considers its highly liquid temporary
investments with original maturities of three months or less to be cash
equivalents. The carrying value of cash and cash equivalents approximate fair
value because of the short-term maturity of these investments.

     GOODWILL Goodwill is amortized on a straight-line basis over periods not
exceeding 40 years. Accumulated amortization was $1,624,000 at March 31, 1996
and $1,584,000 and $1,423,000 at December 31, 1995 and 1994. The Unit maintains
separate financial records for each of its acquired entities and evaluates its
goodwill annually to determine potential impairment by comparing the carrying
value to the undiscounted future cash flows of the related assets. The Unit
modifies the life or adjusts the value of a subsidiary's goodwill if an
impairment is identified. See Note 3 for an impairment identified during 1993.
    
 
     REVENUE RECOGNITION The Unit recognizes revenue from product sales at the
time product is shipped to a customer. Service revenue is recognized at the time
service is provided or ratably over the contractual service period.
 
   
     PRO FORMA INCOME (LOSS) PER SHARE Pro forma income (loss) per share was
computed based on the weighted average number of shares of North Star common
stock outstanding (9,887,000 and 9,836,000 for the periods ended March 31, 1996
and 1995 and 9,650,000, 9,704,000 and 9,438,000 for the years ended December 31,
1995, 1994 and 1993) after giving effect to the assumed exercise of North Star's
outstanding stock options for North Star common stock, except when the effects
are antidilutive. This weighted average number of shares was adjusted to reflect
the distribution of ENStar Inc. common stock to North Star shareholders whereby
one share of ENStar Inc. common stock will be issued to each holder of three
shares of North Star common stock.
    
 
   
     SUPPLEMENTAL DISCLOSURE OF CASH FLOW INFORMATION The Unit increased its
investment in its unconsolidated subsidiary by $70,000, $122,000 and $254,000
and operating unit equity by $42,000, $73,000 and $152,000 during the years
ended December 31, 1995, 1994 and 1993, respectively, as a result of equity
transactions of CorVel. In addition, during those years the Unit had cash
payments for interest of $247,000 in 1995, $348,000 in 1994, and $361,000 in
1993.
    
 
   
     For three months ended March 31, the Unit's investment in its
unconsolidated subsidiary changed by $(3,000) and $234,000, while operating unit
equity changed by $(1,000) and $141,000 during 1996 and 1995.

     RECENTLY ISSUED ACCOUNTING STANDARDS The Financial Accounting Standards
Board has issued two accounting standards which the Unit is required to adopt
January 1, 1996. The first statement establishes guidance on when and how to
measure impairment of long-lived assets and certain identifiable intangibles and
how to value long-lived assets to be disposed of. The second standard
establishes accounting and reporting for the impact of the fair value of
stock-based compensation plans and permits the Unit to select the fair value
based method of accounting for employee stock options or the intrinsic value
method. Upon completion of the distribution described in Note 1, management
intends to adopt the intrinsic value method of accounting and reporting for
stock-based compensation plans. Management believes the adoption of these new
accounting standards will not have a material effect on the Unit's combined
financial statements. During the quarter ended March 31, 1996, the company
adopted these standards, the adoption of which did not have a material effect on
the Unit's combined financial statements.
    
 
     USE OF ESTIMATES In the preparation of the Unit's combined financial
statements, management is required to make estimates and assumptions that affect
the reported amounts of assets and liabilities and related revenues and
expenses. Actual results could differ from the estimates used by management.
 
NOTE 3 -- RESTRUCTURING CHARGES
 
     In December 1993, Americable implemented a restructuring plan involving the
closure of its Canadian facilities, operated by Adanac Cable, Ltd., and
consolidation of its Canadian sales and customer support activities within its
U.S. operations. This plan was completed in 1994. In connection with this
consolidation, Americable recorded a restructuring charge of approximately $1.9
million in 1993. This charge includes approximately $600,000 for the write-off
of goodwill and other noncurrent assets, $700,000 for the reassessment of the
carrying value of inventory and receivables, and $600,000 for lease and
severance obligations and other related expenses.
 
NOTE 4 -- INVESTMENT IN UNCONSOLIDATED SUBSIDIARY

NOTE 6 -- NOTES PAYABLE AND LONG-TERM DEBT
 
   
     Americable and Transition maintain a revolving line of credit and term loan
facility which provides borrowings up to $5.5 million due in May 1996.
Borrowings under this facility are based on eligible accounts receivable and
inventory with interest at prime plus 1.5% (10% at December 31, 1995 and 9.75%
at March 31, 1996). Amounts outstanding under the revolving line of credit at
December 31, 1995 are classified within notes payable to the bank. The term loan
bears interest at 10.665% and is payable in monthly principal installments of
$36,000 with a final installment of $893,000 due in May 1996. The credit
agreement includes certain restrictive covenants including minimum net worth
requirements, limitations on additional indebtedness and minimum interest
coverage. At December 31, 1995 and March 31, 1996, Americable and Transition
were in compliance with the covenants of this agreement. The carrying value of
long-term debt, which approximates fair value, consists of (in thousands):

     To the extent the Unit's financial reporting basis in its investment in
unconsolidated subsidiaries exceeds its tax basis, and is not expected to be
realized in a tax-free manner, the Unit records a deferred income tax liability.
At December 31, 1995, the deferred tax liability includes the initial tax effect
of $1.8 million for the difference in the financial reporting and tax basis of
the Unit's investment in CorVel following its initial public offering along with
income taxes recorded on the equity in earnings of CorVel of $794,000 in 1995,
$664,000 in 1994, and $497,000 in 1993.

     On April 26, 1996, North Star completed the sale of Eagle for approximately
$3.7 million of cash and notes. Eagle has been classified within net assets held
for sale of the Units. A portion of the proceeds from this transaction may be
used by North Star to fund scheduled maturities of their debentures through the
date of the proposed reorganization, which is expected to be completed in 1996.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
Board of Directors and Shareholders of North Star Universal, Inc.
 
     We have audited the accompanying combined statements of operating unit
assets and liabilities of ENStar ("the Unit"), (an operating unit of North Star
Universal, Inc.), as of December 31, 1995 and 1994, and the related combined
statements of operating unit net income, operating unit equity, and cash flows
for each of the three years in the period ended December 31, 1995. These
financial statements are the responsibility of the Unit'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 our audits provide a reasonable basis for our opinion.
 
     In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the combined operating unit assets and
liabilities of ENStar as of December 31, 1995 and 1994, and the combined results
of their operations and their combined cash flows for each of the three years in
the period ended December 31, 1995, in conformity with generally accepted
accounting principles.

ITEM 20. INDEMNIFICATION OF OFFICERS AND DIRECTORS.
 
     Minnesota Statutes Section 302A.521 provides that a corporation shall
indemnify any person made or threatened to be made a party to a proceeding by
reason of the former or present official capacity of such person against
judgments, penalties, fines (including, without limitation, excise taxes
assessed against such person with respect to any employee benefit plan),
settlements and reasonable expenses, including attorneys' fees and
disbursements, incurred by such person in connection with the proceeding, if,
with respect to the acts or omissions of such person complained of in the
proceeding, such person (1) has not been indemnified therefor by another
organization or employee benefit plan; (2) acted in good faith; (3) received no
improper personal benefit and Section 302A.255 (with respect to director
conflicts of interest), if applicable, has been satisfied; (4) in the case of a
criminal proceeding, had no reasonable cause to believe the conduct was
unlawful; and (5) reasonably believed that the conduct was in the best interests
of the corporation in the case of acts or omissions in such person's official
capacity for the corporation or reasonably believed that the conduct was not
opposed to the best interests of the corporation in the case of acts or
omissions in such person's official capacity for other affiliated organizations.
The Articles of Incorporation of ENStar provides that ENStar shall indemnify
officers and directors to the extent permitted by Section 302A.521 as now
enacted or hereafter amended.
 
     ENStar will also maintain an insurance policy or policies to assist in
funding indemnification of directors and officers for certain liabilities.

ITEM 22. UNDERTAKINGS.
 
     (a) The undersigned Registrant hereby undertakes:
 
     (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:
 
         (i) To include any prospectus required by Section 10(a)(3) of the
             Securities Act of 1933;
 
         (ii) To reflect in the prospectus any facts or events arising after the
              effective date of the registration statement (or the most recent
              post-effective amendment thereof) which, individually or in the
              aggregate, represent a fundamental change in the information set
              forth in the registration statement; and
 
        (iii) To include any material information with respect to the plan of
              distribution not previously disclosed in the registration
              statement or any material change to such information in the
              registration statement;
 
     (2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof;
 
     (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.
 
     (b)(1) The undersigned Registrant hereby undertakes as follows: that prior
to any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this Registration Statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.
 
     (2) The Registrant undertakes that every prospectus (i) that is filed
pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Securities Act of 1933 and is used
in connection with an offering of securities subject to Rule 415, will be filed
as a part of an amendment to the Registration Statement and will not be used
until such amendment is effective, and that, for purposes of determining any
liability under the Securities Act of 1933, each such post-effective amendment
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.
 
     (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
 
     (d) The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the Prospectus pursuant to
Items 4, 10(b), 11 or 13 of this Form, within one
 
                                      II-4
<PAGE>   201
 
business day of receipt of such request, and to send the incorporated documents
by first class mail or other equally prompt means. This includes information
contained in documents filed subsequent to the effective date of the
Registration Statement through the date of responding to the request.
 
     (e) The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.

has duly caused this Amendment to the Registration Statement to be signed on its
behalf by the undersigned, thereunto duly authorized, in the City of
Minneapolis, State of Minnesota, on June 11, 1996.
