Acquisition of Digital Communications of Iowa, Inc.

         On January 30, 1997, McLeod, Inc. (the "Company") acquired Digital
Communications of Iowa, Inc., an Iowa corporation ("Digital"), pursuant to the
terms of an Agreement and Plan of Reorganization, dated as of January 27, 1997
(the "Agreement"), by and among Digital, the Company and certain shareholders of
Digital.  Pursuant to the Agreement, Digital was merged with McLeod 1997 Merging
Co. (a newly formed Iowa corporation which was organized as a wholly owned
subsidiary of the Company) in a reverse triangular merger (the "Merger"), with
Digital as the surviving corporation of the Merger, and the outstanding shares
of Digital Common Stock were converted into the right to receive shares of the
Company's Class A Common Stock.  The shareholders of Digital received an
aggregate of 84,428 shares of the Company's Class A Common Stock (the "Offered
Shares") in the Merger in exchange for their shares of Digital Common Stock.
The aggregate value of the Offered Shares was approximately $2.3 million, based
on the average closing sales price of the Class A Common Stock on the Nasdaq
National Market at the time of the transaction.  Digital sells, installs and
services telephone systems primarily to small businesses in eastern Iowa.

         Clark E. McLeod, a director, executive officer and significant
stockholder of the Company, and Mary E. McLeod, a significant stockholder of the
Company, were significant shareholders of Digital.  Mr. McLeod served as a
director of Digital.  A Special Committee of the Board of Directors of the
Company, consisting of disinterested directors, approved the Merger as fair to,
and in the best interests of, the stockholders of the Company.  Prior to January
30, 1997, the Company rented facilities and equipment and purchased maintenance
and installation services from Digital and paid Digital commission on local and
long distance sales to customers of Digital.

         The foregoing description of the Agreement does not purport to be
complete and is qualified in its entirety by the terms and conditions of the
Agreement, which is filed as Exhibit 2 to this Current Report on Form 8-K and is
                             ---------                                          
incorporated herein by reference.

of senior discount notes due 2007 (i) to "qualified institutional buyers" (as
defined in Rule 144A under the Securities Act of 1933), (ii) to a limited number
of institutional "accredited investors" (as defined in Rule 501(a)(1), (2), (3)
or (7) under the 

                                      -2-

Merger, all pursuant to the terms and conditions of this Agreement and a Plan of
Merger in substantially the form of Exhibit A (the "Plan of Merger") and

           with applicable provisions of the laws of the State of Iowa as
           follows:
<PAGE>
 
           2.1.1. Conversion of DIGITAL Shares. All DIGITAL shareholders,
                  ----------------------------
           immediately prior to the Effective Time 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 entitled to receive the
           number of shares of MCLEOD Common Stock as set forth on Exhibit
                                                                   -------
           2.1.1, upon exchange of certificates in Section 7.2.
           -----

     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 DIGITAL, and DIGITAL 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 DIGITAL, 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 stock pursuant to
     Section 2.1.1 and shall be owned by MCLEOD. Each share of such common stock
     issued pursuant to this section shall be fully paid and nonassessable; (d)
     the Board of Directors of the Surviving Corporation will initially consist
     of Stephen C. Gray, Blake O. Fisher, Jr. and David Stanard and the officers
     of the Surviving Corporation will initially be David Stanard - President,
     Blake O. Fisher, Jr. - Treasurer, and Casey D. Mahon - Secretary; and (e)
     the Merger will have all of the effects provided by applicable law, from
     and after the Effective Time.

     2.3. Further Assurances. DIGITAL agrees that if, at any time after the
          ------------------
     Effective Time, MCLEOD considers or is advised that any further acts,
     deeds, assignments or assurances are reasonably necessary or desirable to
     vest the Surviving Corporation with full right, title and possession to any
     property or rights of DIGITAL, then MCLEOD and its proper officers and
     directors may execute and deliver all such proper deeds, assignments and
     assurances and take all other actions necessary or desirable to vest the
     Surviving Corporation with full right, title and possession to such
     property or rights and otherwise to carry out the purpose of this
     Agreement, in the name of DIGITAL or otherwise.

     2.4. Tax Free Exchange. The parties intend to adopt this Agreement as a 
          -----------------
     tax-free plan of reorganization and to consummate the Merger in accordance
     with the provisions of Section 368(a)(1)(A) of the Internal Revenue Code of
     1986, as amended ("Code") by virtue of the provisions of Section
     368(a)(2)(D) of the Code. The parties believe that the value of the MCLEOD
     Common Stock to be issued to the DIGITAL Shareholders (as defined in
     Section 3.5) in the Merger is equal, in each instance, to the value of the
     DIGITAL Common Stock to be surrendered in exchange therefor. No
     consideration that could constitute "other property" within the meaning of

                                       2
<PAGE>
 
     Section 356 of the Code is being paid by MCLEOD for the DIGITAL Common
     Stock in the Merger. The parties agree not to take a position on any tax
     returns, before any taxing authority or otherwise, inconsistent with this
     Section. In addition, MCLEOD represents as of the Agreement Date and as of
     the Closing Date (as that term is defined in Section 7.1), that it
     presently intends to continue DIGITAL's historic business or use a
     significant portion of DIGITAL's business assets in a business. At the
     Closing (as that term is defined in Section 7.1), officers of each of
     MCLEOD and DIGITAL shall execute and deliver officers' certificates
     substantially in the forms of Exhibits 2.4A and 2.4B, respectively. The
                                   ----------------------
     obligations and representations contained or referred to in this Section
     2.4 shall survive the Effective Time without limitation as to time or in
     any other respect.

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

3.   REPRESENTATIONS AND WARRANTIES OF DIGITAL. DIGITAL represents and warrants
to MCLEOD that, except as set forth in a letter addressed to MCLEOD dated the
Agreement Date and delivered by DIGITAL to MCLEOD concurrent herewith (the
"DIGITAL Disclosure Letter") (the contents of which DIGITAL Disclosure Letter
shall be deemed to be representations and warranties made to MCLEOD by DIGITAL
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 as set
forth in Section 9), each of the representations and statements in this Section
are true and correct as of the Agreement Date and will be true as of the Closing
Date.

     3.1.  Organization and Good Standing. DIGITAL (i) is a corporation duly
           ------------------------------
     organized, validly existing, and in good standing under the laws of Iowa,

     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
     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. DIGITAL has the right, power, legal capacity and authority to
           -----
     enter into, execute and deliver this Agreement and all agreements to which
     DIGITAL is or will be a party that are to be executed pursuant to this
     Agreement (collectively, the "DIGITAL Ancillary Agreements") and subject to
     the approval of the Merger by all DIGITAL Shareholders, for the
     consummation of the transactions contemplated by such Agreements. The
     execution and delivery of this Agreement and each of the DIGITAL 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 DIGITAL's Board of Directors.

     3.3.  Authorization. No filing, authorization, consent, approval or order,
           -------------
     is necessary or required for the execution and delivery of this Agreement
     and the DIGITAL Ancillary Agreements by DIGITAL and the DIGITAL
     Shareholders or the consummation of the transactions contemplated by
     agreements, except for (a) the filing of the Articles of Merger with the

     qualified to do business, if any, (b) such filings as may be required to
     comply with federal and state securities laws, and (c) the approval of the
     Merger by the DIGITAL Shareholders .

     3.4.  Validity. This Agreement and the DIGITAL Ancillary Agreements are, or
           --------
     when executed by DIGITAL and/or the DIGITAL Shareholders, as applicable,
     will be, valid and binding obligations of DIGITAL and/or the DIGITAL
     Shareholders, as applicable, 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.

    3.10.  DIGITAL Financial Statements. DIGITAL has delivered to MCLEOD copies
    of each of the following:
    
           3.10.1.  DIGITAL's audited balance sheet as of December 31, 1995 (the
           "DIGITAL Balance Sheet") and audited income statement and statement
           of cash flows for the year then ended (collectively with the DIGITAL
           Balance Sheet, the "1995 DIGITAL Financial Statements"); and

           3.10.2.  DIGITAL's audited balance sheets as of, and DIGITAL's
           audited income statements and statement of cash flows for each of the
           years in the two-year period ended December 31, 1995 (collectively
           the "DIGITAL Financial Statements").

           3.10.3.  DIGITAL's unaudited balance sheet, as of November 30, 1996
           and unaudited income statement and unaudited statement of cash flows
           for the 11-month period then ended (collectively the "DIGITAL
           Unaudited Financial Statements").

    The DIGITAL Financial Statements and DIGITAL Unaudited Financial Statements
(a) accurately reflect the books and records of DIGITAL, (b) fairly present the
consolidated financial condition of DIGITAL as of the respective dates indicated
and the results of operations and changes in financial position for the
respective periods specified, and (c) the DIGITAL Financial Statements have been
prepared in accordance with generally accepted accounting principles applied on
a consistent basis. DIGITAL has no 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 DIGITAL Balance
Sheet, except for those that may have been incurred after the date of the
DIGITAL Balance Sheet in the ordinary course of DIGITAL's business consistent
with past practice, and that are not material in amount either individually or
collectively. All reserves established by DIGITAL and set forth in the DIGITAL
Balance Sheet were reasonably adequate. At November 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 DIGITAL Balance Sheet
as required by such accounting statement.

    3.11.  Title to Properties. DIGITAL has good and marketable title to all of
           -------------------
    its assets and properties reflected on the DIGITAL Balance Sheet, free and
    clear of all liens, 

                                       7

    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 DIGITAL Disclosure Letter sets
    forth a list and brief description of each real property or equipment lease
    which involves payments by DIGITAL in excess of $20,000 annually. A true and
    correct copy of each such lease of DIGITAL has been delivered by DIGITAL to
    MCLEOD prior to the date hereof. All leases of real or personal property to
    which DIGITAL is a party are fully effective and afford DIGITAL 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 DIGITAL as lessee under the terms of such leases for its business
    and in particular, in the case of any leases for real property, DIGITAL 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 DIGITAL. 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
    the giving of notice, or both, would result in any default or prevent
    DIGITAL , currently or after consummation of the transactions contemplated
    by this Agreement and the DIGITAL Ancillary Agreements, from exercising or
    obtaining the benefits thereunder or the benefits of any options contained
    therein. DIGITAL is not 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),
    nor has received any notice of violation with which it has not complied.

                      (d) None of the Real Property is subject to any agreement
           or other restriction of any nature whatsoever (recorded or

           reasonably be expected to have a material adverse effect on its
           business or prospects. DIGITAL does not have any material liability

                      Rights and all related material proprietary rights. All
                      granted and issued patents, all registered trademarks and

                      3.16.3.     To DIGITAL's knowledge, as now used or
                      proposed for use by DIGITAL, none of the DIGITAL 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 DIGITAL and the DIGITAL Shareholders,
                      there is no unauthorized use, infringement or
                      misappropriation of any DIGITAL IP Right by any third
                      party, employee or former employee.

                      3.16.4.     As used in this Section 3.16, the term
                      "Intellectual Property Rights" means, collectively, all

                      constituting, describing or relating to the above,
                      including, without limitation, manuals, memoranda and
                      records.

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

           3.18.      Certain Transactions and Agreements. To DIGITAL's
                      -----------------------------------
           knowledge, none of the officers or directors of DIGITAL, 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 arrangement with DIGITAL (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, or any member of their immediate families, is
           directly or indirectly interested in any contract or arrangement with
           DIGITAL, except for normal compensation for services as an officer,

           (except for amounts due as normal salaries and bonuses and in
           reimbursement of ordinary expenses), and no such person is indebted
           to DIGITAL. DIGITAL is not a party to any (i) agreement with any
           officer or other employee of DIGITAL (A) the benefits of which are
           contingent, or the terms of which are altered, upon the occurrence of
           a transaction involving DIGITAL of the nature of any of the
           transactions

           contemplated by this Agreement or the DIGITAL 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,

           basis of any of the transactions contemplated by this Agreement or
           the DIGITAL Ancillary Agreements.

           3.19.      Employees. To DIGITAL's knowledge, DIGITAL is 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 DIGITAL
           and their current compensation has been made available to MCLEOD.
           DIGITAL has no employment contracts or consulting agreements
           currently in effect that are not terminable at will (other than

           of proprietary information or assignment of inventions).

           3.20.      Labor Relations. To DIGITAL's knowledge, DIGITAL (i) has

           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 DIGITAL's
           knowledge, threatened any labor dispute, strike or work stoppage
           which affects or which may affect DIGITAL's business. Neither DIGITAL
           nor any agents, representatives or employees of DIGITAL 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
           DIGITAL's knowledge, threatened any unfair labor practice charge
           against DIGITAL within the jurisdiction of the National Labor
           Relations Board or any representative thereof.

           3.21.      Employee Benefit Plans / ERISA. Exhibit 3.21 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

<PAGE>
 
           employment agreements entered into between DIGITAL and any employee
           of DIGITAL , but excluding workers' compensation, unemployment
           compensation and other government-mandated programs) currently or
           previously maintained, contributed to or entered into by DIGITAL
           under which DIGITAL or any ERISA Affiliate (as defined below) has any
           present or future obligation or liability (collectively, the "DIGITAL
                                                                         -------
           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 DIGITAL. Copies of all
           DIGITAL Employee Plans (and, if applicable, related trust agreements)
           and all related amendments and written interpretations (including
           summary plan descriptions) have been delivered to MCLEOD. All DIGITAL
           Employee Plans which individually or collectively would constitute an
           "employee pension benefit plan," as defined in Section 3(2) of ERISA
           (collectively, the "DIGITAL Pension Plans"), are identified as such
                               ---------------------
           in Exhibit 3.21. All contributions due from DIGITAL with respect to
              ------------
           any of the DIGITAL Employee Plans have been made as required under
           ERISA or have been accrued on the DIGITAL Financial Statements as of
           December 31, 1996. Each DIGITAL 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 DIGITAL
           Employee Plans.

                      3.21.1.     No DIGITAL Pension Plan constitutes, or has
                      since the enactment of ERISA constituted, a "multi-
                      employer plan," as defined in Section 3(37) of ERISA. No
                      DIGITAL Pension Plan constitutes an Employee Stock
                      Ownership Plan as defined in Section 4975(e)(7) of the
                      Code. No DIGITAL 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 DIGITAL Employee Plan which is covered
                      by Title I of ERISA which would result in a material
                      liability to DIGITAL, 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
                      DIGITAL Employee Plan has or will make DIGITAL or any
                      officer or director of DIGITAL subject to any material
                      liability under Title I of ERISA or liable for any
                      material tax (as defined in Section 3.7) or penalty
                      pursuant to Sections 4972, 4975, 4976 or 4979 of the Code
                      or Section 502 of ERISA.

                      3.21.2.     Any DIGITAL Pension Plan which is intended to
                      be qualified under Section 401(a) of the Code (a "DIGITAL
                                                                       --------
                      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. DIGITAL has made available to
                      MCLEOD a complete

                      and correct copy of the most recent Internal Revenue
                      Service determination letter with respect to each DIGITAL
                      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 DIGITAL 401(a) Plan.

                      ----------------------------  ------------
           employment, severance or other similar contract, arrangement or

           benefits, death benefits, hospitalization benefits, retirement
           benefits, deferred compensation, profit-sharing, bonuses, stock

           which (i) is not a DIGITAL Employee Plan, (ii) is entered into,

           -------------
           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 DIGITAL Benefit Arrangement.

           3.23.      Employee Benefit Costs. There has been no amendment,
                      ----------------------
           written interpretation or announcement (whether or not written) by
           DIGITAL relating to, or change in employee participation or coverage
           under, any DIGITAL Employee Plan or DIGITAL Benefit Arrangement that
           would increase materially the expense of maintaining such DIGITAL
           Employee Plan or DIGITAL Benefit Arrangement above the level of the
           expense incurred for such items for the year ended December 31, 1996.

           3.24.      COBRA Notices. DIGITAL has 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

              (i) was or is defective in any material

           7.2.  Exchange of Certificates.
                 ------------------------

                 stock will surrender to MCLEOD the certificate(s) for such
                 shares (each a "DIGITAL Certificate"), duly endorsed as
                 requested by MCLEOD, to MCLEOD for cancellation. Promptly after

                 MCLEOD will issue to each tendering holder a certificate for
                 the number of shares of MCLEOD Common Stock to which such
                 holder is entitled pursuant to Section 2.1.1 hereof.

                 7.2.2. No dividends or distributions payable to holders of
                 record of MCLEOD Common Stock after the Effective Time, or cash
                 payable in lieu of fractional shares, will be paid to the
                 holder of any unsurrendered DIGITAL Certificate until such
                 holder surrenders such DIGITAL Certificate to MCLEOD as
                 provided above. Subject to the effect, if any, of applicable
                 escheat and other laws, following surrender of any DIGITAL
                 Certificate, there will be delivered to the person entitled
                 thereto, without interest, the amount of any dividends and
                 distributions therefor paid with respect to MCLEOD Common Stock
                 so withheld as of any date subsequent to the Effective Time and
                 prior to such date of delivery.

                 7.2.3. After the Effective Time there will be no further
                 registration of transfers of the DIGITAL Common Stock on the
                 stock transfer books of DIGITAL or its transfer agent. If,
                 after the Effective Time, DIGITAL Certificates are presented
                 for any reason, they will be canceled and exchanged as provided
                 in this Section 7.2.

                 7.2.4. Until DIGITAL Certificates representing DIGITAL Common
                 Stock outstanding prior to the Merger are surrendered pursuant
                 to Section 7.2.1 above, such DIGITAL Certificates will be
                 deemed, for all purposes, to evidence ownership of the number
                 of shares of MCLEOD Common Stock into which such DIGITAL Common
                 Stock would have been converted pursuant to Section 2.1.1.

           them under this Agreement; provided that such limitation on the
                                      --------
           DIGITAL Shareholders' indemnification obligations shall not apply to

           Surviving Corporation and their respective officers, directors,
           agent, affiliates, shareholders and employees, and each person, if
           any, who controls or may control MCLEOD or the Surviving Corporation
           within the meaning of the Securities Act from and against any and all
           damages arising in any manner from (i) any claim for breach of
           Section 3.9 (taxes); (ii) Section 3.21 (Employee Benefit
           Plans/ERISA); (iii) Section 3.22 (DIGITAL Benefit Agreements); (iv)
           Section 3.23 (Employee Benefit Costs); (v) Section 3.24 (COBRA
           Notices); and (vi) Section 3.31 (Environmental Matters).

           11.6. Notice. Promptly after MCLEOD becomes aware of the existence of

           any potential claim by an Indemnified Person for indemnity from the
           DIGITAL Indemnifying Shareholders under Section 11, MCLEOD will
           notify the DIGITAL Indemnifying Shareholders of such potential claim
           (provided that the failure of MCLEOD to give prompt notice shall not
           affect the rights to indemnification, hereunder except to the extent
           the DIGITAL Indemnifying Shareholders demonstrate actual damage
           caused by such failure) and will, to the extent that it can
           reasonably do so without impairing its ability to adequately defend
           and respond to any such claim, permit the DIGITAL Indemnifying
           Shareholders to assist MCLEOD in the defense of such claim and will
           cooperate with the DIGITAL Indemnifying Shareholders in obtaining
           copies of any records or other information which is relevant to the
           defense of such claim. Prior to the settlement of any claim for which
           MCLEOD seeks indemnity from a DIGITAL Indemnifying Shareholder,
           MCLEOD will provide the DIGITAL Indemnifying Shareholders with the
           terms of the proposed settlement and a reasonable opportunity to
           comment on such terms.

12.        INDEMNIFICATION BY MCLEOD. MCLEOD agrees to indemnify and hold
harmless All DIGITAL Shareholders from and against any and all adverse tax
consequences incurred by them including interest and penalties arising out of
any action or omission by MCLEOD or MERGECO which action or omission within two
years of the Effective Date disqualifies the tax-free exchange treatment of the
Merger.

           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.

           13.4. 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.

           13.5. Other Remedies. Except as otherwise provided in this Agreement,

                 ---------------------
           may be amended, and the observance of any term of this Agreement may
