                    INFORMATION TO BE INCLUDED IN THE REPORT

ITEM 5.  OTHER EVENTS.

         On August 15, 1996, McLeod, Inc. (the "Company") entered into
an Agreement and Plan of Reorganization (the "Agreement") with Telecom*USA
Publishing Group, Inc., an Iowa corporation ("Telecom"), pursuant to which a
newly formed subsidiary of the Company will be merged with and into Telecom
(the "Merger"), and Telecom will become a wholly owned subsidiary of the
Company.

         Pursuant to the terms of the Agreement, (i) each outstanding
share of common stock, no par value, of Telecom ("Telecom Common Stock") (other
than shares identified in clause (ii) below and shares as to which dissenters'
rights of appraisal have been perfected under Iowa law) will be converted into
the right to receive $12.75 in cash, and (ii)(a) all the outstanding shares of
Telecom Common Stock owned by Clark E. McLeod, Chairman, Chief Executive
Officer, Director and stockholder of the Company, and his wife, Mary E. McLeod,
(assuming exercise of all options and warrants to purchase Telecom Common
Stock, and conversion of all debentures convertible into Telecom Common Stock,
owned by them) will be converted into the right to receive an aggregate of
$13,598,417 and 192,308 shares of class A common stock, $0.01 par value of the
Company (the "McLeod Common Stock") and (b) all the outstanding shares of
Telecom Common Stock held by the Arthur Christoffersen IRA (Mr. Christoffersen 
is the President and Chief Executive Officer of Telecom) will be converted into
the right to receive an aggregate of 44,135 shares of McLeod Common Stock.  The
Agreement also provides that the Company will have the option to pay an
additional $5,000,008, in aggregate, to Clark and Mary McLeod and an
additional $1,147,500 to Arthur Christoffersen IRA in lieu of issuing the McLeod
Common Stock identified in clause (ii) above if the average of the closing 
price per share of McLeod Common Stock as quoted on The Nasdaq National Market
and reported in The Wall Street Journal for the five days immediately 
preceding (but not including) the effective time of the Merger exceeds $32.50 
per share.

         Consummation of the Merger is subject to the satisfaction of a
number of conditions, including, but not limited to: (i) compliance with all
applicable provisions of the Hart-Scott-Rodino Antitrust Improvements Act of
1976, as amended, and the expiration of all applicable waiting periods
thereunder; (ii) approval of the Agreement and the Merger by the shareholders
of Telecom; (iii) the exercise of dissenters' rights in connection with the
Merger by holders of not more than five percent of the outstanding shares of
Telecom Common Stock; and (iv) certain other customary conditions.  Clark E.
McLeod, Mary E. McLeod, Arthur Christoffersen and certain other shareholders 
of Telecom, owning in the aggregate more than fifty percent of the outstanding
shares of Telecom Common Stock, have entered into a Securityholders Agreement
pursuant to which, among other things, such shareholders have agreed to vote
their shares of Telecom Common Stock in favor of the Agreement and the Merger
at a meeting of Telecom's shareholders.

2.   PLAN OF REORGANIZATION.

     2.1.   The Merger.  Subject to the terms and conditions of this
     Agreement, at the Effective Time, NORTH STAR will be merged with MERGECO
     pursuant to this Agreement and the Plan of Merger and in accordance with
     applicable provisions of the laws of the State of Iowa as follows:

            2.1.1. Conversion of NORTH STAR Shares. Except as provided in
            Section 2.1.2, each share of NORTH STAR Common Stock issued and
            outstanding immediately prior to the Effective Time (other than
            NORTH STAR Dissenting Shares, as defined in Section 2.1.5) will by
            virtue of the Merger and at the Effective Time, and without the
            need for any further action on the part of any holder thereof, be
            converted into the right to receive $12.75 in cash, upon surrender
            of the certificates representing such shares of NORTH STAR Common
            Stock in the manner provided in Section 8.2.

            2.1.2. Other Conversions. Subject to the last sentence of this
            subsection, all shares of NORTH STAR Common Stock owned by Clark
            E. McLeod and Mary E. McLeod, after the exercise of all options,
            warrants and conversion of all debentures, will by virtue of the
            Merger and at the Effective Time, and without the need for any
            further action on their part, be converted into the right to
            receive $13,598,417 and 192,308 shares of BIG DIPPER Common Stock
            upon surrender of the certificates representing such shares of
            NORTH STAR Common Stock in the manner provided in Section 8.2.
            Subject to the last sentence of this subsection, all shares of
            NORTH STAR Common Stock held by the Art Christoffersen IRA will by
            virtue of the Merger and at the Effective Time, and without the
            need for any further action on its part, be converted into the
            right to receive 44,135 shares of BIG DIPPER Common Stock upon
            surrender of the certificates representing such shares of NORTH
            STAR Common Stock in the manner provided in Section 8.2. In the
            event that the average of the closing price per share of BIG DIPPER
            Common Stock as quoted on the NASDAQ National Market and reported
            in The Wall Street Journal for the five (5) days immediately
            preceding (but not including) the Effective Time, exceeds $32.50
            per share, then BIG DIPPER has the option to elect to pay Clark
            McLeod, Mary McLeod and the Art Christoffersen IRA cash instead of
            the amount of BIG DIPPER Common Stock which would require an
            additional cash payment to Clark and Mary McLeod of $5,000,008 and
            as cash payment to the Art Christoffersen IRA of $1,147,500.

            2.1.3. Conversion of Non-Vested Options. All non-vested options to
            purchase NORTH STAR Common Stock outstanding immediately prior to 
            the Effective Time will, by virtue of the Merger and at the 
            Effective Time,


                                       2
<PAGE>   3
          and without the need for any further action on the part of any
          holder thereof, be immediately terminated and be null and void and
          all rights in respect thereof shall cease to exist without any
          payment therefor, and no shares of BIG DIPPER Common Stock or other
          consideration shall be delivered in exchange therefor.  The
          non-vested options shall be replaced with a deferred compensation
          program as described in Exhibit 2.1.3.

          2.1.4.  Dissenters' Rights of NORTH STAR Shareholders.  Any shares of
          NORTH STAR Common Stock entitled to dissenters' rights in connection
          with the Merger under Iowa law ("NORTH STAR Dissenting Shares")
          shall not be converted into cash as provided in Section 2.1.1 or
          cash and shares of BIG DIPPER Common Stock as provided in Section
          2.1.2, but shall be entitled to receive such consideration as may be
          determined to be due with respect to such dissenting shares pursuant
          to the law of the State of Iowa.  NORTH STAR shall give BIG DIPPER
          prompt notice of any demands for appraisal or withdrawals of demands
          for appraisal received by NORTH STAR and any other documents
          obtained by NORTH STAR pursuant to the applicable provisions of Iowa
          law and, except with the prior written consent of BIG DIPPER, shall
          not settle or offer to settle any such demands.

     2.2.  Effects of the Merger.  In addition to the foregoing effects of the
     Merger, at and upon the Effective Time, each of the following will occur:
     (a) the separate existence of MERGECO will cease and MERGECO will be
     merged with and into NORTH STAR, and NORTH STAR will be the surviving
     corporation of the Merger (the "Surviving Corporation") pursuant to the
     terms of the Plan of Merger; (b) the Articles of Incorporation and Bylaws
     of NORTH STAR, as in effect immediately prior to the Effective Time, will
     continue unchanged and will be the Articles of Incorporation and Bylaws
     of the Surviving Corporation until thereafter duly amended; (c) the one
     share of MERGECO common stock outstanding immediately prior to the
     Effective Time will, by virtue of the Merger and without any action on
     the part of any holder thereof, be converted into and become the number
     of shares of common stock of the Surviving Corporation as are converted
     into cash or stock pursuant to Sections 2.1.1 and 2.1.2, and shall be
     owned by BIG DIPPER.  Each share of such common stock issued pursuant to
     this section shall be fully paid and nonassessable; and (d) the Merger
     will have all of the effects provided by the Plan of Merger and
     applicable law, from and after the Effective Time.

     2.3.  Not a Tax Free Exchange.  The parties acknowledge that the
     transaction contemplated by this Agreement shall not qualify as a
     tax-free plan of reorganization.

     2.4.  Purchase Accounting.  The parties hereto acknowledge that the Merger
     will be treated as a purchase for accounting purposes.

warrants to BIG DIPPER that, except as set forth in a letter addressed to BIG
DIPPER dated the Agreement Date and delivered by NORTH STAR to BIG DIPPER
concurrent herewith (the "NORTH STAR DISCLOSURE LETTER") (the contents of
which NORTH STAR Disclosure Letter shall be deemed to be representations and
warranties made to BIG DIPPER by NORTH STAR under this Section 3, and which
may be updated up to the Closing to reflect changes that are not material,
consistent with the conditions to closing set forth in Section 10) each of the
representations and statements in this Section are true and correct as of the
date hereof and as of the Closing Date.

     subsidiaries (i) is a corporation duly organized, validly existing and in
     good standing under the laws of Iowa, (ii) has the corporate power and
     authority to own, operate and lease its properties and to carry on its
     business as now conducted and as proposed to be conducted, and (iii) is
     qualified to transact business as a foreign corporation in each
     jurisdiction in which the nature of its business or the ownership or
     leasing or its properties makes such qualification necessary, other than
     where a failure to be so qualified would not reasonably be expected to
     have a material adverse effect on its present or expected operations or
     financial condition.

     3.2.  Power.  NORTH STAR has the right, power, and authority to enter
     into, execute and deliver this Agreement and all agreements to which
     NORTH STAR is or will be a party that are to be executed pursuant to this
     Agreement (collectively, the "NORTH STAR ANCILLARY AGREEMENTS") and,
     subject to the approval of the Merger by the shareholders of NORTH STAR,
     for the consummation of the transactions contemplated by such agreements. 
     The execution and delivery of this Agreement and each of the NORTH STAR
     Ancillary Agreements and the consummation of the transactions
     contemplated by such agreements have been duly and validly approved and
     authorized by all necessary corporate action on the part of NORTH STAR's
     Board of Directors.

     3.3.  Authorization.  No filing, authorization, consent, approval or order,
     governmental or otherwise, is necessary or required for the execution and
     delivery of this Agreement and the NORTH STAR Ancillary Agreements by
     NORTH STAR or the consummation of the transactions contemplated by such
     agreements, except for (a) the filing of the Articles of Merger with the
     office of the Iowa Secretary of State, and the filing of appropriate
     Merger documents with the relevant authorities of other states in which
     NORTH STAR is qualified to do business, if any, (b) such filings as may
     be required to comply with federal and state securities laws, (c) the
     approval of the Merger by the shareholders of NORTH STAR, and (d) the
     filings required by the Hart-Scott-Rodino Antitrust Improvements Act of
     1976, as amended (the "HSR Act").


                                       4
<PAGE>   5
     3.4.  Validity.  This Agreement and the NORTH STAR Ancillary Agreements
     are, or when executed by NORTH STAR will be, valid and binding
     obligations of NORTH STAR, and enforceable in accordance with their
     respective terms, except as to the effect, if any, of (i) applicable
     bankruptcy and other similar laws affecting the rights of creditors
     generally, and (ii) rules of law governing specific performance,
     injunctive relief and other equitable remedies; provided, however, that
     the Merger will not become effective until the Articles of Merger
     reflecting the Merger are filed with the office of the Iowa Secretary of
     State.

          which are now owned and held, and all of which at the Effective Time
          will be owned and held, only by the shareholders of NORTH STAR as
          set forth on Exhibit 3.5.1, and no other shares of the capital stock
          of NORTH STAR are authorized, issued or outstanding.  All issued and

          requirements (or applicable exemptions) of all applicable federal
          and state securities laws.  A list of all holders of NORTH STAR
          Common Stock, and the number of shares held by each has been
          delivered by NORTH STAR to BIG DIPPER and is reflected on Exhibit
          3.5.1.

          aggregate of 2,359,750 shares of NORTH STAR Common Stock at the
          option of the holders thereof ("NORTH STAR Convertible Debentures"),
          as disclosed on Exhibit 3.5.2, there are no options, warrants,
          exchangeable or convertible securities, puts, calls, commitments,
          conversion privileges or preemptive or other rights or agreements of
          any character to which NORTH STAR is a party or by which NORTH STAR
          is bound to issue, transfer, deliver, sell, redeem, purchase or
          otherwise acquire (whether directly or indirectly) or cause to be
          issued, transferred, delivered, sold, redeemed, purchased or

          any securities convertible into or exchangeable for any shares of
          NORTH STAR's capital stock, and NORTH STAR has no obligation to
          grant, issue, extend, or enter into any such option, warrant,
          exchangeable or convertible security, put, call, commitment,

          Any shares of NORTH STAR Common Stock issued upon exercise of any
          NORTH STAR Option or NORTH STAR Warrant, when issued pursuant to
          exercise of such NORTH STAR Option or NORTH STAR Warrant, and any
          shares of NORTH STAR Common Stock issued upon exercise of any NORTH
          STAR Convertible Debenture, when issued pursuant to such conversion,
          will be validly issued, fully paid and nonassessable and not subject
          to any claim, lien, presumptive right or right of rescission.  The
          terms of the Option Plans permit the assumption or substitution of a
          deferred compensation program as described in Exhibit  2.1.4,
          without the consent of NORTH STAR optionees or shareholders under
          the Option Plans.  The NORTH STAR Options are qualified as incentive
          stock options under Section 422 of the Internal Revenue Code of
          1986, as amended (the "CODE"), other than the options granted to
          directors which are nonqualified.  Exhibit 3.5.2 sets forth (i) the
          name of the holder of record of each NORTH STAR Option, NORTH STAR
          Warrant and NORTH STAR Convertible Debenture, (ii) the number of
          shares of NORTH STAR Common Stock issuable upon exercise of each
          such NORTH STAR Option, (iii) the expiration date of each such NORTH
          STAR Option, NORTH STAR Warrant and NORTH STAR Convertible

          Convertible Debenture.  True and complete copies of all agreements
          and instruments relating to the NORTH STAR Options, NORTH STAR
          Warrants and NORTH STAR Convertible Debentures have been made
          available to BIG DIPPER and such agreements and instruments have not
          been amended, modified or supplemented and there are no agreements
          or commitments to amend, modify or supplement such agreements and
          instruments in each case from the form made available to BIG DIPPER. 
          NORTH STAR has no liability for dividends accrued but unpaid.  To
          the knowledge of NORTH STAR, no person or entity holds or has any
          option, warrant or other right to acquire any issued and outstanding
          shares of the capital stock of NORTH STAR from any holder of shares
          of the capital stock of NORTH STAR.

          3.5.3.  No Voting Arrangements or Registration Rights.  There are no
          voting agreements, voting trusts, or other agreements or
          arrangements with respect to the voting of NORTH STAR's outstanding
          securities and there are no rights of first refusal or other
          restrictions (other than normal restrictions on transfer under
          applicable federal and state securities laws) applicable to any of
          NORTH STAR's outstanding securities or the


                                       6
<PAGE>   7
          conversion of any NORTH STAR securities in the Merger.  NORTH STAR
          is not under any obligation to register any of its outstanding
          securities, or any securities that may be subsequently issued,
          under the Securities Act of 1933, as amended (the "SECURITIES ACT").

     3.6. Subsidiaries.  Except for the subsidiaries of NORTH STAR listed on
     Exhibit 3.6  (collectively the "SUBSIDIARIES" and each a "SUBSIDIARY"),
     each of which is wholly owned by NORTH STAR, NORTH STAR does not have any
     subsidiaries or any interest, direct or indirect, in any corporation,
     partnership, joint venture or other business entity.  All issued and
     outstanding shares of the capital stock of each Subsidiary are validly
     issued, fully paid and nonassessable and are owned and held solely by
     NORTH STAR free and clear of any option, liens, security interests,
     claims, charges or encumbrances.  There are no outstanding options,
     warrants, exchangeable or convertible securities, puts, calls,
     commitments, conversion privileges or preemptive or other rights or
     agreements of any character to which any Subsidiary is a party or by
     which any Subsidiary is bound to issue, transfer, deliver, sell, redeem,
     purchase or otherwise acquire (whether directly or indirectly) or cause
     to be issued, transferred, delivered, sold, redeemed, purchased or
     otherwise acquired, (i) any shares of capital stock of any Subsidiary, or
     (ii) any securities convertible into or exchangeable for any shares of
     capital stock of any Subsidiary, and no Subsidiary has any obligation to
     grant, issue, extend, or enter into any such option, warrant,
     exchangeable or convertible security, put, call, commitment, conversion
     privilege or preemptive or other rights or agreements.

     3.7. No Violation of Existing Agreements.  Neither the execution and
     delivery of this Agreement nor any NORTH STAR Ancillary Agreement, nor
     the consummation of the transactions contemplated by such agreements,
     will conflict with, or (with or without notice or lapse of time, or both)
     result in:

          3.7.1.  a termination, breach, impairment or violation of (i) any
          provision of the Articles of Incorporation or Bylaws of NORTH STAR
          or any Subsidiary, as currently in effect or (ii) any federal,
          state, local or foreign judgment, writ, decree, order, statute, rule
          or regulation applicable to NORTH STAR or any Subsidiary or their
          respective assets or properties; or

          3.7.2.  a termination, or a material breach, impairment or violation
          of, any material instrument, agreement, contract or commitment to
          which NORTH STAR or any Subsidiary is a party or by which NORTH STAR
          or any Subsidiary or their respective assets or properties are
          bound.

     3.8.  Litigation.  There is no action, suit, arbitration, proceeding,
     claim, or investigation pending or to NORTH STAR's knowledge, threatened
     against NORTH STAR, or any Subsidiary before any court, administrative
     agency or


                                       7
<PAGE>   8
     arbitrator (each a "Claim") that may reasonably be expected to have a
     material adverse effect on the present or future operations or financial
     condition of NORTH STAR or any Subsidiary if such Claim is decided
     adversely to NORTH STAR or any Subsidiary.

          3.8.1.  To NORTH STAR's knowledge, there is no basis for any person
          or entity to assert a Claim against NORTH STAR or any Subsidiary
          based upon (i) ownership, rights to ownership, or options, warrants
          or other rights to acquire ownership, of any shares of the capital
          stock of NORTH STAR or any Subsidiary, or (ii) any rights as a
          holder of NORTH STAR Common Stock, including any option, warrant or
          preemptive rights or rights to notice or to vote.

          3.8.2.  To the best of NORTH STAR's knowledge, there is no basis for
          any party to successfully assert a Claim for any material damages
          against NORTH STAR or any Subsidiary based on a claim that any
          product or service developed, owned, marketed, or distributed by
          NORTH STAR or any Subsidiary (i) was or is defective in any material
          respect, or did not or will not perform in accordance with any
          warranty, (ii) was not or is not suitable for a use for which it was
          intended, (iii) omitted or omits necessary information, or (iv)
          included or includes forms of documents, advice or information that
          was negligently prepared and/or marketed, inaccurate or incomplete
          in any respect, or did not conform to or comply with applicable law.

          3.8.3.  There is no judgment, decree, injunction, rule or order of
          any governmental entity or agency, court or arbitrator outstanding
          against NORTH STAR or any Subsidiary.

     3.9.  Taxes.  NORTH STAR and each of its Subsidiaries have (i) timely
     filed all federal, state, local and foreign tax returns required to be
     filed and such returns are true and correct in all material respects,
     (ii) timely paid all taxes required to be paid in respect of all periods
     for which returns have been filed, (iii) established an adequate accrual
     or reserve for the payment of all taxes payable in respect of the periods
     subsequent to the periods covered by the most recent applicable tax
     returns, (iv) made all necessary estimated tax payments, and (v) has no
     material liability for taxes in excess of the amount so paid or accruals
     or reserves so established.  Neither NORTH STAR nor any Subsidiary is
     delinquent in the payment of any tax or is delinquent in the filing of
     any tax returns and no deficiencies for any tax have been threatened,
     claimed, proposed or assessed.  Neither NORTH STAR nor any Subsidiary has
     received any notification that any material issues have been raised (and
     are currently pending) by the Internal Revenue Service or any other
     taxing authority (including but not limited to any

                                       8
<PAGE>   9
     sales tax authority).  No tax return of NORTH STAR or any Subsidiary has
     ever been audited by the Internal Revenue Service or any state taxing
     agency or authority.  No tax liens have been filed against any assets of
     NORTH STAR or any Subsidiary.  NORTH STAR is not a "personal holding
     company" within the meaning of Section 542 of the Code.  There are no
     outstanding agreements or waivers extending the statutory period of
     limitations applicable to any tax return of NORTH STAR or any Subsidiary
     for any period.  For the purposes of this section, the terms "TAX" and
     "TAXES" include all federal, state, local and foreign income, alternative
     or add-on  minimum income, gains, franchise, excise, property, sales,
     use, employment, license, payroll, ad valorem, stamp, occupation,
     recording, value added or transfer taxes, governmental charges, fees,
     customs duties, levies or assessments (whether payable directly or by
     withholding), and, with respect to such taxes, any estimated tax,
     interest and penalties or additions to tax and interest on such penalties
     and additions to tax.

     3.10.  NORTH STAR Financial Statements.  NORTH STAR has delivered to BIG
     DIPPER copies of each of the following:

          3.10.1.  NORTH STAR's audited consolidated balance sheet as of
          August 31, 1995 (the "NORTH STAR Balance Sheet") and audited
          consolidated income statement and consolidated statement of cash
          flows for the year then ended (collectively with the NORTH STAR
          Balance Sheet, the "1995 NORTH STAR Financial Statements");

          3.10.2.  NORTH STAR's audited consolidated balance sheets as of, and
          NORTH STAR's audited consolidated income statements and consolidated
          statement of cash flows for each of the years in the three-year
          period ended August 31, 1994 (collectively the "NORTH STAR Audited
          Financial Statements"); and

          3.10.3.  NORTH STAR's unaudited consolidated balance sheet, as of
          June 30, 1996 and unaudited consolidated income statement and
          unaudited consolidated statement of cash flows for the ten-month
          period then ended (collectively the "NORTH STAR Unaudited Financial
          Statements").

     The NORTH STAR Audited Financial Statements and NORTH STAR Unaudited
Financial Statements (a) accurately reflect the books and records of NORTH
STAR and its Subsidiaries, (b) fairly present the consolidated financial
condition of NORTH STAR and its Subsidiaries as of the respective dates
indicated and the consolidated results of operations and changes in financial
position for the respective periods specified, and (c) have been prepared in
accordance with generally accepted accounting principles applied on a
consistent basis.  Neither NORTH STAR nor any Subsidiary has any material
debt, liability or obligation of any nature, whether accrued, absolute,
contingent or otherwise, and whether due or to become due, that is not
reflected or reserved against in the 


                                       9
<PAGE>   10
NORTH STAR Balance Sheet, except for those that may have been incurred after
the date of the NORTH STAR Balance Sheet in the ordinary course of NORTH
STAR's business consistent with past practice, and that are not material in
amount either individually or collectively.  All reserves established by NORTH
STAR and set forth in the NORTH STAR Balance Sheet were reasonably adequate. 
At June 30, 1996, there were no material loss contingencies (as such term is
used in Statement of Financial Accounting Standards No. 5 issued by the
Financial Accounting Standards Board in March 1975) which are not adequately
provided for in the NORTH STAR Unaudited Financial Statements as required by
such accounting statement.

     3.11.  Title to Properties.  NORTH STAR and each of its Subsidiaries have
     good and marketable title to all of their respective assets and
     properties reflected on the NORTH STAR Balance Sheet, free and clear of
     all liens, mortgages, security interests, claims, charges, restrictions
     or encumbrances.  All machinery, vehicles, equipment and other tangible
     personal property included in such assets and properties are in good
     condition and repair, normal wear and tear excepted.  The NORTH STAR
     Disclosure Letter sets forth a list and brief description of each real
     property or equipment lease which involves payments by NORTH STAR or any
     Subsidiary in excess of $100,000 annually.  A true and correct copy of
     each such lease of NORTH STAR and each Subsidiary has been delivered by
     NORTH STAR to BIG DIPPER prior to the date hereof.  All leases of real or
     personal property to which NORTH STAR or any Subsidiary is a party are
     fully effective and afford NORTH STAR or each Subsidiary peaceful and
     undisturbed possession of the subject matter of such leases.  Any
     property (real or personal) covered by the terms of such leases is
     presently occupied or used by NORTH STAR or its Subsidiaries as lessee
     under the terms of such leases for its business and in particular, in the
     case of any leases for real property, NORTH STAR or its Subsidiaries is
     entitled, by the terms of such leases and under applicable laws, rules
     and regulations, to use any leased premises for the purposes for which
     and in the manner in which they are currently being used by NORTH STAR
     and its Subsidiaries.  All rentals due under such leases have been paid
     and there exists no default under any such leases, and no event has
     occurred which, upon the passage of time or giving of notice, or both,
     would result in any default or prevent NORTH STAR or any Subsidiary,
     currently or after consummation of the transaction contemplated by this
     Agreement and the NORTH STAR Ancillary Agreement, from exercising or
     obtaining the benefits thereunder or the benefits of any options
     contained therein.  Neither NORTH STAR nor any Subsidiary is in violation
     of any zoning, building, safety or environmental ordinance, regulation or
     requirement or other law or regulation applicable to the operation of
     owned or leased properties (the violation of which would have a material
     adverse effect on its business), or has received any notice of violation
     with which it has not complied.  Neither NORTH STAR nor any Subsidiary
     owns any real property.

     3.12.  Absence of Certain Changes.  Since the date of the NORTH STAR
     Balance Sheet, NORTH STAR and each of its Subsidiaries have conducted
     their business only in the ordinary course in a manner consistent with
     past practice and, since such date, there has not been any:

          3.12.1.  material adverse change in the condition (financial or
          otherwise), properties, assets, liabilities, businesses, operations,
          results of operations or prospects of NORTH STAR and any Subsidiary,
          taken as a whole;

          3.12.2.  amendments or changes in the Articles of Incorporation or
          Bylaws of NORTH STAR or any Subsidiary;

          3.12.3.  (i) incurrence, creation, assumption or guarantee by NORTH
          STAR or any Subsidiary of (A) any mortgage, security interest,
          pledge, lien or other encumbrance on any of the assets or properties
          of NORTH STAR or any Subsidiary or (B) any material obligation or
          liability or any indebtedness for borrowed money in excess of a
          cumulative aggregate amount (computed with reference to all
          transactions described in (A) or (B) of this clause) of $50,000; or
          (ii) issuance or sale of any debt or equity securities of NORTH STAR
          or any Subsidiary or any options or other rights to acquire from
          NORTH STAR or any Subsidiary, directly or indirectly, any debt or
          equity securities of NORTH STAR or any Subsidiary;

          3.12.4.  payment or discharge of a material lien or liability for
          such lien that was not either shown on the NORTH STAR Balance Sheet
          or incurred in the ordinary course of business after the date of the
          NORTH STAR Balance Sheet;

          3.12.5.  purchase, license, sale or other disposition, or any
          agreement or other arrangement for the purchase, license, sale or
          other disposition, of any of the assets or properties of NORTH STAR
          or any Subsidiary other than in the ordinary course of business;

          3.12.6.  damage, destruction or loss, whether or not covered by
          insurance, materially and adversely affecting the properties, assets
          or business of NORTH STAR or any Subsidiary;

          3.12.7.  declaration, setting aside or payment of any dividend on,
          or the making of any other distribution in respect of, the capital
          stock of NORTH STAR or any Subsidiary, any split, combination or
          reclassification of the capital stock of NORTH STAR or any
          Subsidiary, or any direct or indirect redemption, purchase or other
          acquisition of the capital stock of

                                      11
<PAGE>   12
          NORTH STAR or any Subsidiary, or any change in any rights,
          preferences, privileges or restrictions of any outstanding security
          of NORTH STAR or any Subsidiary;

          3.12.8.  change or increase in the compensation payable or to become
          payable to any of the officers, employees or agents of NORTH STAR or
          any Subsidiary, or any bonus or pension, insurance or other benefit
          payment or arrangement (including without limitation stock awards,
          stock appreciation rights or stock option grants) made to or with
          any of such officers, employees or agents, except in connection with
          normal employee salary or performance reviews or otherwise in the
          ordinary course of business consistent with past practice;

          officers;

          3.12.11.  making of any loan, advance or capital contribution to, or

          3.13.7.  agreement containing any covenant purporting to restrict
          NORTH STAR or any Subsidiary from engaging in any aspect of its
          business or competing in any line of business in any geographic
          area;

          3.13.8.  agreement involving any NORTH STAR IP Rights (as defined in
          Section 3.15 below);

          3.13.9.  any agreement relating to the sale, issuance, grant,
          exercise, award, purchase, repurchase or redemption of any shares of
          capital stock or other securities of NORTH STAR or any Subsidiary or
          any options, warrants or other rights to purchase or otherwise
          acquire any such shares of capital stock, other securities or
          options, warrants or other related rights; or

          3.13.10.  any other agreement, contract, commitment or instrument
          that is material to the business of NORTH STAR or any Subsidiary or
          involves a commitment in excess of $100,000.

     A copy of each contract, agreement, commitment or other instrument
required to be listed on Exhibit 3.13 has been delivered to BIG DIPPER's
General Counsel.

     3.14.  No Default.  Neither NORTH STAR nor any Subsidiary, nor to the best
     knowledge of NORTH STAR any other party thereto, is in breach or default
     in any material respect under any contract, agreement, commitment or
     other instrument or obligation that is required to be listed on Exhibit
     3.13 or that is otherwise material to the business of NORTH STAR or any
     Subsidiary, and all such contracts, agreements, commitments or other
     instruments or obligations are in full force and effect.  Neither NORTH
     STAR nor any Subsidiary is a party to any contract, agreement or
     arrangement which has had or could reasonably be expected to have a
     material adverse effect on its business or prospects.  Neither NORTH STAR
     nor any Subsidiary has any material liability for renegotiation of
     government contracts or subcontracts, if any.

     3.15.  Intellectual Property.  NORTH STAR and each of its Subsidiaries
     own, license or have the right to use all material Intellectual Property
     Rights (as defined below) necessary or required for the conduct of their
     respective businesses as presently conducted (collectively, the "NORTH
     STAR IP Rights"), and such NORTH STAR IP Rights are sufficient for such
     conduct of its business.

          3.15.1.  NORTH STAR and each of its Subsidiaries have taken
          reasonable and practicable steps designed to protect, preserve and
          maintain the secrecy and confidentiality of all NORTH STAR IP Rights
          and all related proprietary rights.  All granted and issued patents,
          all registered


                                      14
<PAGE>   15
          trademarks and all copyrights listed on Exhibit 3.15 are valid and
          subsisting.

          3.15.2.  Exhibit 3.15 contains a list of all NORTH STAR IP Rights,
          including, without limitation, all patents, patent applications,
          copyrights (whether or not registered), copyright applications,
          trademarks or service marks (whether or not registered) or trademark
          or service mark applications.

          3.15.3.  To NORTH STAR's knowledge, as now used or proposed for use
          by NORTH STAR or any Subsidiary, none of the NORTH STAR IP Rights
          has infringed, misappropriated or otherwise violated, or is likely
          to violate, directly or indirectly, any Intellectual Property Right
          of any third party.  To the best knowledge of NORTH STAR, there is
          no unauthorized use, infringement or misappropriation of any NORTH
          STAR IP Right by any third party, employee or former employee.

          3.15.4.  As used in this Section 3.15, the term "Intellectual
          Property Rights" means, collectively, all worldwide industrial and
          intellectual property rights, including, without limitation,
          patents, patent applications, patent rights, trademarks, trademark
          applications, trade names, service marks, service mark applications,
          copyrights, copyright applications, franchises, licenses,
          inventions, know-how, trade secrets, customer lists, proprietary
          processes and formulae, software source and object code, algorithms,
          architecture, structure, display screens, layouts, inventions,
          development tools and all documentation and media constituting,
          describing or relating to the above, including, without limitation,
          manuals, memoranda and records.

     3.16.  Compliance with Laws.  To NORTH STAR's knowledge, NORTH STAR and
     each of its Subsidiaries have complied in all material respects with all
     applicable federal, state, local or foreign laws, ordinances,
     regulations, and rules, and all orders, writs, injunctions, awards,
     judgments, and decrees applicable to them and their respective assets,
     properties, and business (the violation of which would have a material
     adverse effect upon their business).  NORTH STAR and each of its
     Subsidiaries hold all permits, licenses and approvals from, and have made
     all filings with, third parties, including government agencies and
     authorities, that are necessary in connection with its present business.

     3.17.  Certain Transactions and Agreements.  To NORTH STAR's knowledge,
     none of the officers or directors of NORTH STAR or any Subsidiary, nor
     any member of their immediate families, has any direct or indirect
     ownership interest in any entity that competes with, or does business
     with, or has any contractual


                                      15
<PAGE>   16
     arrangement with NORTH STAR (except with respect to any interest in less
     than one percent (1%) of the stock of any corporation whose stock is
     publicly traded).  None of such officers or directors, nor any member of
     their immediate families, is directly or indirectly interested in any
     contract or arrangement with NORTH STAR, except for normal compensation
     for services as an officer, director or employee that have been disclosed
     to BIG DIPPER.  Neither NORTH STAR nor any Subsidiary is indebted to any
     director, officer, employee or agent of NORTH STAR or any Subsidiary
     (except for amounts due as normal salaries and bonuses and in
     reimbursement of ordinary expenses), and no such person is indebted to
     NORTH STAR or any Subsidiary.  Neither NORTH STAR nor any Subsidiary is a
     party to any (i) agreement with any officer or other employee of NORTH
     STAR or any Subsidiary (A) the benefits of which are contingent, or the
     terms of which are altered, upon the occurrence of a transaction
     involving NORTH STAR or any Subsidiary of the nature of any of the
     transactions contemplated by this Agreement or the NORTH STAR Ancillary
     Agreements, (B) providing severance benefits or other benefits (which are
     conditioned upon a change of control) after the termination of employment
     of such employee regardless of the reason for such termination of
     employment or (C) providing for bonuses, pensions, deferred compensation,
     retirement payments, profit sharing or similar payments, which in the
     case of (A), (B) or (C) is not terminable by NORTH STAR or any Subsidiary
     on ten days notice or less without penalty or obligation to make payments
     related to such termination, or (ii) agreement or plan, including without
     limitation, any stock option plan, stock appreciation right plan or stock
     purchase plan, any of the benefits of which will be increased, or the
     vesting of benefits of which will be accelerated, by the occurrence of
     any of the transactions contemplated by this Agreement or the NORTH STAR
     Ancillary Agreements or the value of any of the benefits of which will be
     calculated on the basis of any of the transactions contemplated by this
     Agreement or the NORTH STAR Ancillary Agreements.

     3.18.  Employees.  To NORTH STAR's knowledge, NORTH STAR and each of its
     Subsidiaries are in compliance in all material respects with all
     applicable laws, agreements, contracts and other arrangements relating to
     employment, employment practices, wages, hours, and terms and conditions
     of employment, including, but not limited to, employee compensation
     matters.  A list of all employees, officers and consultants of NORTH STAR
     and its Subsidiaries and their current compensation has been made
     available to BIG DIPPER.  Neither NORTH STAR nor any Subsidiary has any
     employment contracts or consulting agreements currently in effect that
     are not terminable at will (other than agreements for the sole purpose of
     providing for the confidentiality of proprietary information or
     assignment of inventions).

     3.19.  Labor Relations.  To NORTH STAR's knowledge, neither NORTH STAR
     nor any of its Subsidiaries (i) has ever been or is now subject to a
     union organizing


                                      16
<PAGE>   17
     effort, (ii) is subject to any collective bargaining agreement with
     respect to any of its employees, (iii) is subject to any other contract
     or agreement, written or oral, with any trade or labor union, employees'
     association or similar organization, and (iv) has any current labor
     disputes.  NORTH STAR and each of its Subsidiaries have good labor
     relations, and have no knowledge of any facts indicating that the
     consummation of the transactions contemplated hereby will have a material
     adverse effect on such labor relations, and has no knowledge that any of
     its key employees intends to leave its employ.  There is neither pending
     nor, to the best knowledge of NORTH STAR, threatened any labor dispute,
     strike or work stoppage which affects or which may affect NORTH STAR's or
     any Subsidiary's business.  Neither NORTH STAR nor any Subsidiary, nor
     any agents, representatives or employees of NORTH STAR or any Subsidiary
     has committed any unfair labor practice as defined in the National Labor
     Relations Act of 1947, as amended, and there is not now pending nor, to
     the best knowledge of NORTH STAR, threatened any unfair labor practice
     charge against NORTH STAR or any Subsidiary within the jurisdiction of
     the National Labor Relations Board or any representative thereof.

     3.20.  Employee Benefit Plans / ERISA.  Exhibit 3.20 identifies (i) each
     "employee benefit plan," as defined in Section 3(3) of the Employee
     Retirement Income Security Act of 1974, as amended ("ERISA"), and (ii)
     all other written or formal plans or agreements involving direct or
     indirect compensation or benefits (including any employment agreements
     entered into between NORTH STAR or any Subsidiary and any employee of
     NORTH STAR or any Subsidiary, but excluding workers' compensation,
     unemployment compensation and other government-mandated programs)
     currently or previously maintained, contributed to or entered into by
     NORTH STAR or any Subsidiary under which NORTH STAR or any Subsidiary or
     any ERISA Affiliate (as defined below) has any present or future
     obligation or liability (collectively, the "NORTH STAR Employee Plans").
     For purposes of this Section, "ERISA Affiliate" means any entity which is a
     member of (A) a "controlled group of corporations," as defined in Section
     414(b) of the Code, (B) a group of entities under "common control," as
     defined in Section 414(c) of the Code, or (C) an "affiliated service
     group," as defined in Section 414(m) of the Code, or treasury regulations
     promulgated under Section 414(o) of the Code, any of which includes NORTH
     STAR or any Subsidiary.  Copies of all NORTH STAR Employee Plans (and, if
     applicable, related trust agreements) and all related amendments and
     written interpretations (including summary plan descriptions) have been
     delivered to BIG DIPPER.  All NORTH STAR Employee Plans which
     individually or collectively would constitute an "employee pension
     benefit plan," as defined in Section 3(2) of ERISA (collectively, the
     "NORTH STAR Pension Plans"), are identified as such in Exhibit 3.20. All
     contributions due from NORTH STAR or any Subsidiary with respect to any
     of the NORTH STAR Employee Plans have been made as required under ERISA
     or have been accrued on the NORTH


                                      17
<PAGE>   18
     STAR Unaudited Financial Statements as of June 30, 1996.  Each NORTH STAR
     Employee Plan has been maintained in compliance with its terms and with
     the requirements prescribed by any and all statutes, orders, rules and
     regulations, including, without limitation, ERISA and the Code which are
     applicable to such NORTH STAR Employee Plans.

          3.20.1.  No NORTH STAR Pension Plan constitutes, or has since the
          enactment of ERISA constituted, a "multi-employer plan," as defined
          in Section 3(37) of ERISA.  No NORTH STAR Pension Plan constitutes
          an Employee Stock Ownership Plan as defined in Section 4975(e)(7) of
          the Code.  No NORTH STAR Pension Plans are subject to Title IV of
          ERISA.  No "prohibited transaction," as defined in Section 406 of
          ERISA or Section 4975 of the Code, has occurred with respect to any
          NORTH STAR Employee Plan which is covered by Title I of ERISA which
          would result in a material liability to NORTH STAR, excluding
          transactions effected pursuant to a statutory or administrative
          exemption.  Nothing done or omitted to be done and no transaction or
          holding of any asset under or in connection with any NORTH STAR
          Employee Plan has or will make NORTH STAR or any officer or director
          of NORTH STAR subject to any material liability under Title I of
          ERISA or liable for any material tax (as defined in Section 3.9) or
          penalty pursuant to Sections 4972, 4975, 4976 or 4979 of the Code or
          Section 502 of ERISA.

          3.20.2.  Any NORTH STAR Pension Plan which is intended to be
          qualified under Section 401(a) of the Code (a "NORTH STAR 401(a)
          Plan") is so qualified and has been so qualified during the period
          from its adoption to date, and the trust forming a part of such plan
          is exempt from tax pursuant to Section 501(a) of the Code.  NORTH
          STAR has made available to BIG DIPPER a complete and correct copy of
          the most recent Internal Revenue Service determination letter with
          respect to each NORTH STAR 401(a) Plan.  Nothing has occurred since
          the date of the most recent applicable Internal Revenue Service
          determination letter that would adversely affect the qualified
          status of any NORTH STAR 401(a) Plan.

     3.21.  NORTH STAR Benefit Arrangements. Exhibit 3.20 lists each
     employment, severance or other similar contract, arrangement or policy
     and each plan or arrangement (written or oral) providing for insurance
     coverage (including any self-insured arrangements), workers' benefits,
     vacation benefits, severance benefits, disability benefits, death
     benefits, hospitalization benefits, retirement benefits, deferred
     compensation, profit-sharing, bonuses, stock options, stock purchase,
     phantom stock, stock appreciation or other forms of incentive
     compensation or post-retirement insurance, compensation or benefits for
     employees, consultants or directors which (i) is not a NORTH STAR
     Employee Plan, (ii) is entered into,

                                      18
<PAGE>   19
     maintained or contributed to by NORTH STAR or any Subsidiary and (iii)
     covers any employee or former employee of NORTH STAR or any Subsidiary
     (collectively, the "NORTH STAR Benefit Arrangements").  Each NORTH STAR
     Benefit Arrangement has been maintained in substantial compliance with
     its terms and with the requirements prescribed by any and all statutes,
     orders, rules and regulations that are applicable to such NORTH STAR
     Benefit Arrangement.

     3.22.  Employee Benefit Costs.  There has been no amendment, written
     interpretation or announcement (whether or not written) by NORTH STAR or
     any Subsidiary relating to, or change in employee participation or
     coverage under, any NORTH STAR Employee Plan or NORTH STAR Benefit
     Arrangement that would increase materially the expense of maintaining
     such NORTH STAR Employee Plan or NORTH STAR Benefit Arrangement above the
     level of the expense incurred for such items for the year ended December
     31, 1995.

     3.23.  COBRA Notices.  NORTH STAR and each Subsidiary have provided to
     the individuals entitled thereto all notices and coverages that are
     required by Section 4980B of the Code and the Consolidated Omnibus Budget
     Reconciliation Act of 1985, as amended ("COBRA"), with respect to any
     "qualifying event" (as defined in Section 4980B(f)(3) of the Code)
     occurring prior to and including the Closing Date.  No material tax
     payable under Section 4980B. of the Code has been incurred with respect
     to any current or former employees (or their beneficiaries) of NORTH
     STAR.

     3.24.  Other Employee Matters.  No benefit payable or which may become
     payable by NORTH STAR or any Subsidiary pursuant to any NORTH STAR
     Employee Plan or any NORTH STAR Benefit Arrangement or as a result of or
     arising under this Agreement shall constitute an "excess parachute
     payment" (as defined in Section 280G(b)(1) of the Code) which is subject
     to the imposition of an excise tax under Section 4999 of the Code, or
     which would not be deductible by reason of Section 280G of the Code. 
     Neither NORTH STAR nor any Subsidiary is a party to any agreement with
     any executive officer or other key employee (i) the benefits of which are
     contingent, or the terms of which would become materially altered because
     of the transactions contemplated by this Agreement, (ii) that provides
     any term of employment or compensation guarantee, or (iii) that provides
     severance benefits or other benefits after the termination of employment
     of such employee regardless of the reason for such termination of
     employment.  Neither NORTH STAR nor any Subsidiary is a party to any
     agreement or plan, including, without limitation, any stock option plan,
     stock appreciation rights plan or stock purchase plan, under which (i)
     the benefits will be materially increased, (ii) the vesting of benefits
     of which will be materially accelerated, or (iii) the calculation of the
     value of any of the benefits will be affected by the transactions
     contemplated by this Agreement.

                                      19
<PAGE>   20
     3.25.  Corporate Document.  NORTH STAR has made available to BIG DIPPER
     for examination all documents and information listed in the NORTH STAR
     Disclosure Letter or other exhibits of this Agreement, including, without
     limitation, the following: (i) copies of NORTH STAR's and each
     Subsidiary's Articles of Incorporation and Bylaws as currently in effect;
     (ii) NORTH STAR's and each Subsidiary's minute book containing all
     records of all proceedings, consents, actions, and meetings of NORTH
     STAR's and each Subsidiary's shareholders, board of directors and
     committees; (iii) NORTH STAR's and each Subsidiary's stock ledger and
     journal reflecting all stock issuances and transfers; and (iv) all
     permits, orders, and consents issued by any regulatory agency with
     respect to NORTH STAR or any Subsidiary, or any securities of NORTH STAR
     or any Subsidiary, and all applications for such permits, orders, and
     consents.

     3.26.  No Brokers.  Neither NORTH STAR nor any shareholder of NORTH STAR
     is obligated for the payment of fees or expenses of any investment
     banker, broker or finder in connection with the origin, negotiation or
     execution of this Agreement or the transaction contemplated by this
     Agreement.

     3.27.  Books and Records.  The books, records and accounts of NORTH STAR
     and each Subsidiary (i) are in all material respects true, complete and
     correct, (ii) have been maintained in accordance with good business
     practices on a basis consistent with prior years, (iii) are stated in
     reasonable detail and accurately and fairly reflect the transactions and
     dispositions of the assets of NORTH STAR and each Subsidiary, and (iv)
     are appropriately, accurately and fairly reflected in the NORTH STAR
     Financial Statements.

     3.28.  Internal Controls.  NORTH STAR and each Subsidiary have devised
     and maintain a system of internal accounting controls sufficient to
     provide reasonable assurances that (i) transactions are executed in
     accordance with management's general or specific authorization, (ii)
     transactions are recorded as necessary to permit preparation of financial
     statements in conformity with generally accepted accounting principles or
     any other criteria applicable to such statements, and to maintain
     accountability for assets, and (iii) the amount recorded for assets on
     the books and records of NORTH STAR and each Subsidiary is compared with
     the existing assets at reasonable intervals and appropriate action is
     taken with respect to any differences.

     3.29.  Insurance. NORTH STAR and each Subsidiary maintain, and at all
     times during the prior three years have maintained, fire and casualty,
     general liability, product liability, and sprinkler and water damage
     insurance in amounts which NORTH STAR believes to be reasonably prudent
     for similarly sized and similarly situated businesses under valid and
     enforceable policies issued by insurers of

                                      20
<PAGE>   21
     recognized responsibility.  Each such policy is listed and briefly
     described in the NORTH STAR Disclosure Letter.

     3.30.  Environmental Matters.  During the period that NORTH STAR and each
     Subsidiary have leased or owned their properties or owned or operated any
     facilities, there have been no disposals, releases or threatened releases
     of Hazardous Materials (as defined below) on, from or under such
     properties or facilities.  NORTH STAR has no knowledge of any presence,
     disposals, releases or threatened releases of Hazardous Materials on,
     from or under any of such properties or facilities, which may have
     occurred prior to NORTH STAR or any Subsidiary having taken possession of
     any of such properties or facilities.

          3.30.1.  The terms "disposal", "release", and "threatened release"
          have the meaning as defined in the Comprehensive Environmental
          Response, Compensation and Liability Act of 1980, 42 U.S.C. Section
          9601 et seq., as amended ("CERCLA").

          3.30.2.  The term "Hazardous Materials" means any hazardous or toxic
          substance, material or waste which is or becomes prior to the
          Closing regulated under, or defined as a "hazardous substance,"
          "pollutant," "contaminant," "toxic chemical," "hazardous materials,"
          "toxic substance" or "hazardous chemical" under CERCLA, any similar
          federal, state or local law, or regulations promulgated under any of
          the above laws or statutes.

          3.30.3.  To NORTH STAR's knowledge, none of the properties or
          facilities of NORTH STAR or any Subsidiary is in violation of any
          federal, state or local law, ordinance, regulation or order relating
          to industrial hygiene or to the environmental conditions on, under
          or about such properties or facilities, including, but not limited
          to, soil and ground water condition.  During the time that NORTH
          STAR or any Subsidiary has owned or leased their respective
          properties and facilities, neither NORTH STAR nor any Subsidiary
          nor, to NORTH STAR's knowledge, any third party, has used,
          generated, manufactured or stored on, under or about such properties
          or facilities or transported to or from such properties or
          facilities any Hazardous Materials.

          or leased their respective properties and facilities, there has been
          no litigation brought or threatened against NORTH STAR or any
          Subsidiary, or any lessor or owner of real property leased by NORTH
          STAR or any Subsidiary by, or any settlement reached by NORTH STAR
          or any Subsidiary with, any party or parties alleging the presence,
          disposal, release


                                      21
<PAGE>   22
          or threatened release of any Hazardous Materials on, from or under
          any of such properties or facilities.

     3.31.  Disclosure.  No statement by NORTH STAR contained in this Agreement,
     its exhibits, the NORTH STAR Disclosure Letter, or any of the
     certificates or documents to be delivered by NORTH STAR to BIG DIPPER
     under this Agreement, taken together, contains or will contain any untrue
     statement of a material fact or omits or will omit to state any material
     fact necessary in order to make the statements contained herein or
     therein, in light of the circumstances under which such statements were
     made, not misleading.

     (including any adjournment thereof) is held to consider the Merger and
     the transactions contemplated thereby, contains or will contain any
     untrue statement of a material fact or omits or will omit to state any
     material fact required to be stated therein or necessary in order to make
     the statements therein, in light of the circumstances under which they
     are made, not misleading.

     financial advisor William Blair & Company, that in its opinion, as of the

     shareholders of NORTH STAR.

     proposed to be conducted, and (iii) is qualified to transact business as
     a foreign corporation in each jurisdiction in which the nature of its
     business or the ownership or leasing of its properties makes such

     the Merger by all necessary corporate action, for the consummation of the
     transactions contemplated hereby and thereby.  The execution and delivery
     of this Agreement and each of the BIG DIPPER Ancillary Agreements and the

     action by the board of directors of BIG DIPPER.  Upon MERGECO's
     formation, MERGECO will have the right, power, and authority to execute
     and perform its obligations under the Plan of Merger and all other
     agreements to which MERGECO is to be a party that are to be executed by
     MERGECO pursuant to this Agreement.

     4.3.  Authorization.  No filing, authorization, consent, approval or
     order, is necessary or required for the execution and delivery of this
     Agreement and the BIG DIPPER Ancillary Agreements by BIG DIPPER or the
     consummation of the transactions contemplated by such agreements, except
     as disclosed in the BIG DIPPER Disclosure Letter and except for (a) the
     filing of the Articles of Merger with the Office of the Iowa Secretary of
     State, and the filing of appropriate Merger documents with the relevant
     authorities of other states in which BIG DIPPER or MERGECO is qualified

     of (i) applicable bankruptcy and other similar laws affecting the rights
     of creditors generally, and (ii) rules of law governing specific
     performance, injunctive relief and other equitable remedies;


                                      23
<PAGE>   24

     provided, however, that the Merger will not become effective until the
     Articles of Merger are filed with the office of the Iowa Secretary of
     State.

          4.5.2.  No Other Commitments.  Except for the BIG DIPPER Options and

          otherwise acquire (whether directly or indirectly) (i) any shares of
          BIG DIPPER's authorized but unissued capital stock, or (ii) any
          securities convertible into or exchangeable for any shares of BIG
          DIPPER's capital stock.  BIG DIPPER has no obligations to grant,

          of first refusal or other restrictions (other than normal
          restrictions on transfer under applicable federal and state
          securities laws) applicable to any of BIG DIPPER's

                                      24
<PAGE>   25
          outstanding securities.  BIG DIPPER is not under any obligation to
          register any of its presently outstanding securities or any
          securities that may be subsequently issued under the Securities Act.

     4.6.  No Violation of Existing Agreements.  Except as disclosed in the BIG
     DIPPER Disclosure Letter, neither the execution and delivery of this
     Agreement nor any BIG DIPPER Ancillary Agreement, nor the consummation of
     the transactions contemplated by such agreements, will conflict with, or
     (with or without notice or lapse of time, or both) result in:

          4.6.1.  a termination, breach, impairment or violation of (i) any
          provision of the Articles of Incorporation or Bylaws of BIG DIPPER,
          as currently in effect or (ii) any federal, state, local or foreign
          judgment, writ, decree, order, statute, rule or regulation
          applicable to BIG DIPPER or its assets or properties; or

          4.6.2.  a termination, or a material breach, impairment or violation
          of, any material instrument, agreement, contract or commitment to
          which BIG DIPPER is a party or by which BIG DIPPER is bound.  The
          transfer of the BIG DIPPER Common Stock to certain shareholders of
          NORTH STAR under this Agreement will not require the consent of any
          third party with respect to any material rights, licenses,
          franchises, leases or agreements of BIG DIPPER.

     4.7.  Litigation.  There is no action, suit, claim, arbitration,
     proceeding, or investigation pending or threatened, to BIG DIPPER's
     knowledge, against BIG DIPPER before any court, administrative agency or
     arbitrator (each a "BIG DIPPER Claim") that may reasonably be expected to
     have a material adverse effect on the present or future operations or
     financial condition of BIG DIPPER, if such BIG DIPPER Claim is decided
     adversely to BIG DIPPER.

          4.7.1.  To BIG DIPPER's knowledge, there is no basis for any person
          or entity to assert a BIG DIPPER Claim against BIG DIPPER based upon
          (i) ownership, rights to ownership, or options, warrants or other
          rights to acquire ownership, of any shares of the capital stock of
          BIG DIPPER, or (ii) any rights as a BIG DIPPER shareholder,
          including any option, warrant or preemptive rights or rights to
          notice or to vote.

          4.7.2.  To BIG DIPPER's knowledge, there is no basis for any party
          to successfully assert a BIG DIPPER Claim for any material damages
          against BIG DIPPER based on a claim that any product or service
          developed, owned, marketed, or distributed by BIG DIPPER (i) was or
          is defective in any material respect, or did not or will not perform
          in accordance with any

                                      25
<PAGE>   26
          warranty, (ii) was not or is not suitable for a use for which it was
          intended, (iii) omitted or omits necessary information, or (iv)
          included or includes forms of documents, advice or information that
          was negligently prepared and/or marketed, inaccurate or incomplete
          in any respect, or did not conform to or comply with applicable law.

          4.7.3.  There is no judgment, decree, injunction, rule or order of
          any governmental entity or agency, court or arbitrator outstanding
          against BIG DIPPER.

     connection with the initial public offering of BIG DIPPER Common Stock
     (the "BIG DIPPER PROSPECTUS"), this Agreement, the BIG DIPPER Disclosure
     Letter, the exhibits and schedules hereto, and any certificates or
     documents to be delivered to the certain shareholders of NORTH STAR
     identified in Section 2.1.2, pursuant to this Agreement, as of their
     respective dates did not, and when taken together, do not, contain or
     will not contain any untrue statement of a material fact or omit or will
     omit to state any material fact necessary in order to make the statements
     contained herein or therein, in light of the circumstances under which
     such statements were made, not misleading.

     4.9.  BIG DIPPER Financial Statements.  The financial statements of BIG
     DIPPER included in the BIG DIPPER Prospectus complied as to form in all
     material respects with the then applicable accounting requirements and
     the published rules and regulations of the Securities and Exchange
     Commission (the "SEC"), with respect thereto, were prepared in accordance
     with generally accepted accounting principles applied on a consistent
     basis during the periods involved (except as may have been indicated in
     the notes thereto or, in the case of the unaudited statements, as
     permitted by Form S-1 promulgated by the SEC) and fairly present
     (subject, in the case of the unaudited statements, to normal year end
     audit adjustments) the consolidated financial position of BIG DIPPER and
     its consolidated subsidiaries as at the respective dates thereof and the
     consolidated results of their operations and cash flows.

5.   ADDITIONAL AGREEMENTS.

     5.1.  Proxy Statement.  As promptly as practicable after the execution and
     delivery of this Agreement, NORTH STAR shall prepare and distribute to
     the shareholders of NORTH STAR in accordance with applicable law the
     Proxy Materials.  The Proxy Materials shall include a recommendation of
     the Board of Directors of NORTH STAR in favor of the Merger, which
     recommendation shall not be changed, unless the Board of Directors of
     NORTH STAR, upon receipt of an unsolicited written proposal or offer
     which qualifies as a "bona fide offer" within the meaning of Section 5.4,
     shall determine that to include such recommendation

                                      26
<PAGE>   27
     or not withdraw such recommendation if previously included is reasonably
     likely to result in a breach of the Board's fiduciary duty under
     applicable law.

     5.2.  Access to Information.  For so long as this Agreement is in effect,
     NORTH STAR shall afford to BIG DIPPER and to BIG DIPPER's accountants,
     counsel and other representatives, reasonable access during normal
     business hours during the period prior to the Effective Time to all of
     NORTH STAR's properties, books, contracts, commitments and records and,
     during such period, each party shall use reasonable efforts to furnish
     promptly to each other party (a) a copy of each report, schedule and
     other document filed or received by it during such period pursuant to the
     requirements of federal and state securities laws and (b) all other
     information concerning its business, properties and personnel as such
     other party may reasonably request, provided that no party shall be
     required to disclose any information which it is legally required to keep
     confidential or which is subject to attorney-client privilege.

     5.3.  NORTH STAR Shareholder Meeting.  NORTH STAR shall call a special
     meeting of its shareholders to be held as promptly as practicable after
     the date hereof for the purpose of voting upon the Merger and other
     matters contemplated thereby.  NORTH STAR will use its best efforts to
     solicit from the shareholders of NORTH STAR proxies in favor of the
     Merger, and such other matters as may be necessary to consummate the
     transactions contemplated by this Agreement.

     5.4.  No Other Bids.  During the period from the Agreement Date and
     continuing until the Effective Time, NORTH STAR will not directly or
     indirectly through any subsidiary, officer, director or otherwise, make,
     solicit, initiate or encourage submission of proposals or offers from any
     persons (including any of its officers of employees) relating to any
     liquidation, dissolution, recapitalization, merger, consolidation or the
     acquisition of all or a material portion of the assets of, or any
     controlling equity interest in NORTH STAR or any Subsidiary or other
     similar transaction or business combination involving NORTH STAR or any
     subsidiary, and will not directly or indirectly participate in any
     negotiations regarding, or furnish to any other person any information
     with respect to, or otherwise cooperate in any way with, or assist or
     participate in, facilitate or encourage any effort or attempt by any
     other person to do or seek any of the foregoing, and shall immediately
     cease and cause to be terminated all such contracts or negotiations with
     third parties.  Notwithstanding anything contained in this Section 5.4 to
     the contrary, if NORTH STAR shall receive an unsolicited written offer or
     proposal relating to such transaction from a prospective buyer which
     offer or proposal, including any financing thereof, has been determined
     by the Board of Directors of NORTH STAR, upon receipt of advice of its
     investment banker to be on terms financially superior to the Merger (a
     "bona fide offer"), it may thereafter furnish information relating to it
     to such buyer in connection with such bona fide offer.  Following receipt
     of any bona fide offer, NORTH STAR may

                                      27
<PAGE>   28
     negotiate with the person making such offer or proposal and may, if the
     Board of Directors of NORTH STAR determines that such bona fide offer is
     reasonably likely to result in a transaction that is financially superior
     to the Merger and is otherwise in the best interests of its stockholders,
     enter into a letter of intent or agreement with such person in order to
     pursue or consummate the transaction set forth in the bona fide offer. 
     NORTH STAR shall promptly notify BIG DIPPER orally and in writing of any
     effort or attempt by any person to do or seek any of the foregoing. 
     NORTH STAR recognizes and acknowledges that a breach of this Section 5.4
     may cause irreparable and material loss and damage to BIG DIPPER as to
     which BIG DIPPER may not have an adequate remedy at law or in damages and
     that, accordingly, NORTH STAR agrees that the issuance of an injunction
     or other equitable remedy is the appropriate remedy for any such breach
     and that in the event that the transactions described in this Agreement
     are not consummated because of NORTH STAR's acceptance of a bid or
     proposal relating to such transactions from another bidder, of if this
     Agreement is terminated pursuant to Section 11.1.4, then NORTH STAR will
     promptly pay BIG DIPPER a termination fee equal to five percent (5%) of
     the value of the cash and stock to have been delivered and issued under
     Section 2.1 and 8.2.

     5.5.  Breach by BIG DIPPER.  If this Agreement is terminated pursuant to
     Section 11.1.3  as a result of a material breach of any covenant or
     agreement contained in this Agreement on the part of BIG DIPPER and such
     breach has not been cured within thirty days after written notice to BIG
     DIPPER, then BIG DIPPER will promptly pay to NORTH STAR a termination fee
     equal to five percent (5%) of the value of the cash and stock to have
     been delivered under Section 2.1. NORTH STAR agrees that this termination
     fee shall be its sole and exclusive remedy for a material breach by and
     failure to complete the transactions contemplated by BIG DIPPER.

     5.6.  Legal Conditions to the Merger.  Each party will take all
     reasonable actions necessary to comply with all legal requirements which
     may be imposed on such party with respect to the Merger and will promptly
     cooperate with and furnish information to the other party in connection
     with any such requirements imposed upon such other party or any
     subsidiary of such other party in connection with the Merger.  Each party
     will take, and will cause its subsidiaries to take, all reasonable
     actions to obtain (and to cooperate with the party and its subsidiaries
     in obtaining) any consent, authorization, order or approval of, or any
     exemption by, any court, administrative agency or commission or other
     governmental authority or instrumentality, domestic or foreign, or other
     third party, required to be obtained or made by such party or its
     subsidiaries (or by the other party or its subsidiaries) in connection
     with the Merger or the taking of any action contemplated thereby or by
     this Agreement or the Plan of Merger.


                                      28

     5.7.  Indemnification and Insurance.  Following the Effective Time, to the
     extent permitted by law, the indemnification provisions of BIG DIPPER's
     Certificate of Incorporation and Bylaws shall apply to the officers and
     directors of NORTH STAR who shall become officers of BIG DIPPER.  BIG
     DIPPER shall cause NORTH STAR to continue NORTH STAR's indemnification
     obligations as in effect on the date hereof to its officers and directors
     after the consummation of the Merger.

     President and Treasurer, Tom Anderson as Vice President, Henry Hey as
     Vice President, Bruce Scheff as Vice President, Cathy Smith as Vice

     Board of Directors.  Officers of the Surviving Corporation shall have the

     to BIG DIPPER which will require 25% of the amount of cash each is to
     receive under Section 2.1.1 to be placed in escrow, to be paid out over
     two years, subject to their continued employment with NORTH STAR.  These
     agreements will be delivered at Closing.

     5.9.  Public Announcements.  Upon execution of this Agreement, BIG DIPPER
     and NORTH STAR will issue a press release approved by both parties
     announcing the agreement to enter into the Merger.  BIG DIPPER and NORTH
     STAR shall cooperate with each other in releasing information concerning
     this Agreement and the transactions contemplated herein.  Where
     practicable each of the parties shall furnish to the other drafts of all
     releases prior to publication and each party agrees, prior to the
     consummation of the Merger, to refrain from issuing any statement or
     communication to the public with respect to the transactions contemplated
     hereby without the prior written consent of the other party, which
     consent shall not be unreasonably withheld.  Nothing contained herein
     shall prevent either party at any time from furnishing any information to
     any governmental agency or from issuing any release where it reasonably
     believes it is legally required to do so.

     5.10.  Hart-Scott-Rodino Filing.  Each of BIG DIPPER and NORTH STAR will
     promptly prepare and file the applicable notices (if any) required to be

     pertaining to NORTH STAR, and all work papers directly related to the
     preparation and formulation of the 1996 NORTH STAR Financial Statements
     and personnel responsible for preparing or maintaining such books,
     records and documents.

     5.12.  Best Efforts and Further Assurances.  Each of the parties to this
     Agreement shall use its best efforts to effectuate the transactions
     contemplated hereby and to fulfill and cause to be fulfilled the
     conditions to the Closing under this Agreement.  Each party hereto, at
     the reasonable request of the other party hereto, shall execute and
     deliver such other instruments and do and perform such other acts and
     things as may be necessary or desirable for effecting completely the
     consummation of this Agreement and the transactions contemplated hereby. 
     If, at any time after the Effective Time, any such further action is
     necessary or desirable to carry out the purposes of this Agreement and to
     vest the Surviving Corporation with full right, title and possession to
     all assets, property, rights, privileges, powers and franchises of NORTH
     STAR and its Subsidiaries, then BIG DIPPER and its officers and directors
     are fully authorized in the name of their respective corporations or
     otherwise to take, and will take, all such lawful and necessary action.

     representations and warranties and agreements in this Agreement or in any
     instrument delivered pursuant to this provision shall be deemed to be
     conditions to the Merger and shall not survive the Merger except for the
     provisions of Articles 2 and 12, Sections 3.5, 5.7, 5.8, 5.11, 5.12, 8.2
     and the last sentence of Section 5.2 and the agreements delivered
     pursuant to Sections 10.10 and 10.17, which shall survive the Merger.

     12.2.  Governing Law.  The internal laws of the State of Iowa
     (irrespective of its choice of law principles) will govern the validity
     of this Agreement, the construction of its terms, and the interpretation
     and enforcement of the rights and duties of the parties to this
     Agreement.

     12.3.  Assignment, Binding Upon Successors and Assigns.  No party to this
     Agreement may assign any of its rights or obligations under this
     Agreement without the prior written consent of the other party.  This
     Agreement will be binding upon and inure to the benefit of the parties
     and their respective successors and permitted assigns.

     12.4.  Severability.  If any portion of this Agreement shall be held to
     be invalid or unenforceable for any reason, the remaining provisions
     shall continue to be valid and enforceable so as to reasonably effect the
     intent of the parties.  The parties further agree to replace such invalid
     or unenforceable provision with a valid and enforceable provision that
     will achieve, to the extent possible, the economic, business and other
     purposes of the void or unenforceable provision.

     12.5.  Counterparts.  This Agreement may be executed in separate
     counterparts, each of which shall be deemed an original, but all of which
     together shall constitute one and the same instrument.

<PAGE>   43
     12.6.  Other Remedies.  Except as otherwise provided in this Agreement,
     any and all remedies expressly conferred upon a party in this Agreement
     will be deemed cumulative, with and not exclusive of any other remedy
     conferred by this Agreement or by law.  The exercise of any one remedy
     will not preclude the exercise of any other remedy.

     12.7.  Amendment and Waivers.  Any term or provision of this Agreement
     may be amended, and the observance of any term of this Agreement may be
     waived (either generally or in a particular instance and either
     retroactively or prospectively) only by a writing signed by the party to
     be bound thereby.  The waiver by a party of any breach of this Agreement
     or default in the performance of this Agreement will not be deemed to
     constitute a waiver of any other default or any succeeding breach or
     default.

     12.8.  No Waiver.  The failure of any party to enforce any of the
     provisions of this Agreement shall not be construed to be a waiver of the
     right of such party to enforce such provisions at a subsequent time.

     12.9.  Expenses.  Each party will bear its respective expenses and legal
     fees incurred with respect to this Agreement, and the transactions
     contemplated under this Agreement.

     12.10.  Attorneys' Fees.  If a suit is brought to enforce or interpret
     any part of this Agreement, the prevailing party will be entitled to
     recover, as an element of the costs of suit and not as damages,
     reasonable attorneys' fees to be fixed by the court (including without
     limitation, costs, expenses and fees on any appeal).  The prevailing
     party will be entitled to recover its costs of suit, regardless of
     whether such suit proceeds to final judgment.

     permitted under this Agreement will be in writing and will be either hand
     delivered in person, sent by telecopier, sent by certified or registered

FOR IMMEDIATE RELEASE
 
MCLEOD, INC. AGREES TO ACQUIRE TELECOM*USA
PUBLISHING GROUP, INC.
 
Cedar Rapids, IA, August 15 - McLeod, Inc. (NASDAQ/NMS:MCLD) announced today
that it has signed an agreement to acquire 100% of the outstanding shares of
TELECOM*USA Publishing Group, Inc. in a cash and stock transaction valued at up
to $81.5 million. The agreement remains subject to the satisfaction of certain
conditions.
 
McLeod, Inc. is a provider of integrated local and long distance services to
business and residential customers primarily in Iowa and Illinois. On June 21,
1996, McLeod, Inc. introduced its new PrimeLine(R) service to residential
customers in the Cedar Rapids and Iowa City markets. PrimeLine includes local
phone service, long distance, voice mail, Internet access and paging.
 
"This alliance will provide us the opportunity to optimize and simplify our
marketing and customer service efforts for our business and residential
customers," said Steve Gray, President and Chief Operating Officer of McLeod,
Inc. "This combination will create opportunities for McLeod to extend its
relationship with its customers through nearly three million directories that
TELECOM*USA Publishing currently distributes in McLeod's targeted upper midwest
region."

over 600 full- and part-time staff. TELECOM*USA Publishing had revenue of
approximately $61 million for the twelve-month period ended July 31, 1996 and
publishes approximately 8 million telephone directories in about 5,000 
communities in 15 states in the midwestern United States. As a wholly owned 
subsidiary of McLeod, Inc., TELECOM*USA Publishing would continue to operate

executives who now work at McLeod.
 
Arthur Christoffersen commented on the synergies between McLeod, Inc. and
TELECOM*USA Publishing. "Our customer base and publishing services complement
McLeod's sales efforts in both the business and residential markets. The merger
of our companies represents a strategic alliance between an independent
telephone directory publisher and a company like McLeod, Inc. which provides
extensive and innovative packages of services. I look forward to the benefits
this partnership provides for our customers and employees."
 
The acquisition agreement was signed on August 15, 1996 and its is expected that
the acquisition will be completed in September or October of this year.
