(1)  The Registration Statement relates to the securities of the Registrant
     issuable to holders of common stock of Dakota Telecommunications Group,
     Inc., a Delaware corporation ("DTG"), in the proposed merger of a wholly
     owned subsidiary of the Registrant with and into DTG.
(2)  The number of shares to be registered is based upon the product of (a) the
     number of shares of Common Stock, no par value per share, of DTG ("DTG
     Common Stock") outstanding as of October 27, 1998, assuming the exercise of
     all DTG stock options (whether or not currently exercisable) multiplied by
     (b) a fixed exchange ratio of 0.4328.
(3)  Pursuant to Rule 457(f)(2), because there is currently no public trading
     market for DTG Common Stock, the registration fee was computed on the basis
     of the book value of the shares of common stock of DTG computed as of
     September 30, 1998. Such book value equaled $5,310,251 in the aggregate
     and, based on 2,692,321 shares outstanding September 30, 1998, equaled
     $1.97237 per share.

     THE REGISTRANT HEREBY AMENDS THIS REGISTRATION STATEMENT ON SUCH DATE OR
DATES AS MAY BE NECESSARY TO DELAY ITS EFFECTIVE DATE UNTIL THE REGISTRANT SHALL
FILE A FURTHER AMENDMENT WHICH SPECIFICALLY STATES THAT THIS REGISTRATION
STATEMENT SHALL THEREAFTER BECOME EFFECTIVE IN ACCORDANCE WITH SECTION 8(A) OF
THE SECURITIES ACT OF 1933, OR UNTIL THE REGISTRATION STATEMENT SHALL BECOME
EFFECTIVE ON SUCH DATE AS THE COMMISSION, ACTING PURSUANT TO SAID SECTION 8(A),
MAY DETERMINE.

McLeodUSA provides integrated communications services to business and
residential customers in the Midwestern and Rocky Mountain regions of the United
States.  Our integrated communications services include local, long distance,
Internet access, data, voice mail and paging, all from a single company on a
single bill.  We believe we are the first communications provider in most of our
markets to offer ``one-stop shopping'' for communications services tailored to
customers' specific needs.

Our approach makes it easier for both our business and our residential customers
to satisfy their telecommunications needs.  It also allows businesses to receive
customized services, such as competitive long distance pricing and enhanced
calling features, that might not otherwise be directly available on a cost-
effective basis.  As of September 30, 1998, we served over 366,800 local lines
in 267 cities and towns.

In addition to our core business of providing competitive local, long distance
and related communications services, we also derive revenue from:

 . sale of advertising space in telephone directories
 . incumbent local exchange services in east central Illinois
 . communications network maintenance services
 . telephone equipment sales, service and installation
 . video services
 . special access, private line and data services
 . telemarketing services
 . other communications services, including cellular, operator, payphone and
  paging services

In most of our markets, we compete with the incumbent local phone company by
leasing their lines and switches.  This allows customers to select our local
service without changing their existing telephone numbers.  In other markets,
primarily in east central Illinois, we operate our own lines and switches.  We
provide long distance services by using our own facilities and leasing capacity
from long-haul and local providers.  We are constructing fiber optic networks in
Iowa, Illinois, Wisconsin, Indiana, Missouri, Minnesota, South Dakota and North
Dakota to carry additional communications traffic on our own network.

     . telecommunications equipment sale and leasing services
     . cable television services
     . computer networking services
     . Internet access and related services

We are a Delaware corporation organized in 1997.  Our predecessor was Dakota
Cooperative Telecommunications, Inc., a stock-based South Dakota cooperative
association that was formed on April 3, 1952.  In July 1997, the Cooperative was
converted into a South Dakota corporation and subsequently merged with and into
DTG.


THE MERGER (PAGE __)

The Merger Agreement provides that Merger Sub would merge with and into DTG and
DTG would become a wholly owned subsidiary of McLeodUSA.  McLeodUSA and DTG hope
to complete the Merger by the end of the first quarter of 1999.

The Merger Agreement is included as Appendix A to this Prospectus and Proxy
Statement.  It is the legal document that governs the Merger.


EXCHANGE OF SHARES (PAGE ___)

As a result of the Merger, each share of DTG Common Stock that you own would be
converted into the right to receive 0.4328 of a share of McLeodUSA Common Stock.

You would not receive fractional shares of McLeodUSA Common Stock.  Instead, you
would receive a check in payment for any fractional shares based on the market
value of McLeodUSA Common Stock.

For example:

     .  If you own 10,000 shares of DTG Common Stock, after the Merger you would
        receive 4,328 shares of McLeodUSA Common Stock.
 
     .  If you own 100 shares of DTG Common Stock, after the Merger you would
        receive 43 shares of McLeodUSA Common Stock and a check for the market
        value of the remaining .28 of a share.

In addition, unexercised options to buy DTG Common Stock would be replaced by
options to buy McLeodUSA Common Stock.  Each option to buy a share of DTG Common
Stock would be replaced by an option to buy 0.4328 of a share of McLeodUSA
Common Stock.

Following the Merger, you will receive a letter of transmittal that will provide
instructions on the procedure for exchanging your share certificates
representing DTG Common Stock for share certificates representing McLeodUSA
Common Stock.  For more information on how this exchange procedure works, see
"Exchange of Certificates; Fractional Shares" on page __.

PLEASE DO NOT SEND YOUR STOCK CERTIFICATES AT THIS TIME.

RECOMMENDATION OF THE DTG BOARD (PAGE __)

The DTG Board believes that the Merger is fair to and in the best interests of
DTG and DTG stockholders, and unanimously recommends that DTG stockholders vote
"FOR" the proposal to adopt the Merger Agreement.


REASONS FOR THE MERGER (PAGE ___)

The DTG Board considered a variety of factors in making its decision to approve
the Merger Agreement and to recommend to the DTG stockholders that they vote
their shares for adoption of the Merger Agreement.  These factors included:

     . the business and financial condition of DTG and McLeodUSA
     . the business advantages of a combination
     . the alternatives to the Merger
     . the historical value of DTG Common Stock and the value offered by the
       Merger
     . that McLeodUSA Common Stock is traded on The Nasdaq Stock Market, but
       there is no established public trading market for DTG Common Stock

                                       2
<PAGE>
 
- --------------------------------------------------------------------------------
     . the terms and conditions of the Merger Agreement and the tax-free nature
       of the Merger
     . the presentation and opinion of Duff & Phelps, the DTG Board's financial
       advisor
     . the opportunity of DTG stockholders to participate in the potential
       future value of McLeodUSA

After considering these and other factors, the DTG Board concluded that the
Merger is fair to and in the best interests of DTG and DTG stockholders.


OPINION OF DTG'S FINANCIAL ADVISOR (PAGE __)

Duff & Phelps has given the DTG Board its opinion that the proposed merger is
fair to the holders of DTG Common Stock from a financial point of view.

This opinion is included as Appendix B to this Prospectus and Proxy Statement.


CERTAIN FEDERAL INCOME TAX CONSEQUENCES (PAGE __)


DTG expects that the exchange of shares of DTG Common Stock for shares of
McLeodUSA Common Stock in the Merger would not cause DTG stockholders generally
to recognize gain or loss for United States federal income tax purposes.  DTG
stockholders would, however, have to recognize gain in connection with any cash
received for fractional shares.

The parties' obligations to complete the Merger are conditioned on their receipt
of legal opinions concerning the federal income tax treatment of the Merger.
These opinions won't bind the Internal Revenue Service (the "IRS"), which could
take a different view.

DETERMINING THE ACTUAL TAX CONSEQUENCES OF THE MERGER TO YOU CAN BE COMPLICATED.
THEY WILL DEPEND ON YOUR SPECIFIC SITUATION AND ON VARIABLES NOT WITHIN THE
CONTROL OF DTG OR MCLEODUSA.  YOU SHOULD CONSULT YOUR OWN TAX ADVISOR FOR A FULL
UNDERSTANDING OF THE MERGER'S TAX CONSEQUENCES TO YOU.

You should also refer the more detailed discussion of tax consequences and
opinions at page ___.


ACCOUNTING TREATMENT (PAGE __)

McLeodUSA and DTG expect the Merger to be accounted for using the purchase
method of accounting.


NO APPRAISAL RIGHTS (PAGE __)

DTG stockholders have no right to be paid the appraised value of their shares of
DTG Common Stock in connection with the Merger.

WHAT IS NEEDED TO COMPLETE THE MERGER (PAGE __)

Several conditions must be satisfied before the Merger will be completed.  These
include:

     .  adoption of the Merger Agreement and approval of the Merger by the DTG
        stockholders
     .  approval of the Merger by certain federal, state and local regulatory
        authorities
     .  consent to the Merger by certain third parties
     .  receipt of certain tax opinions
     .  certain other contractual conditions set forth in the Merger Agreement

If the law permits, McLeodUSA or DTG may each waive conditions for the benefit
of their company and stockholders and complete the Merger even though one or
more of these conditions hasn't been met.  There is no assurance that the
conditions will be satisfied or waived or that the Merger will occur.


GOVERNMENTAL AND REGULATORY APPROVALS (PAGE __)

On November 19, 1998, DTG and McLeodUSA were granted early termination of the
premerger waiting period by the Federal Trade Commission ("FTC").  However,
certain state and other regulatory authorities will also need to approve or
be notified of the Merger before it can be completed.  DTG and McLeodUSA have
filed, or expect to soon file, all of the required applications or notices with
these regulatory authorities.  
- --------------------------------------------------------------------------------

                                       3
<PAGE>
 
- --------------------------------------------------------------------------------
While neither of us know of any reason why they would not be able to obtain the
necessary approvals in a timely manner, neither DTG nor McLeodUSA can be certain
when or if they will receive them.

TERMINATION OF THE MERGER AGREEMENT; EXPENSES (PAGE __)

McLeodUSA and DTG may mutually agree at any time to terminate the Merger
Agreement without completing the Merger, even if the DTG stockholders have
approved it.  Also, either of us may decide, without the consent of the other,
to terminate the Merger Agreement if:

 .  The other party breaches the Merger Agreement in a way that would entitle the
   terminating party not to complete the Merger, and the breaching party doesn't
   correct the breach promptly

 .  Any court or governmental entity issues a final order or judgment preventing
   the completion of the Merger

 .  The holders of a majority of the outstanding shares of DTG Common Stock do
   not vote to adopt the Merger Agreement

 .  The Merger has not been completed by August 15, 1999 (subject to 60 days
   extension), unless the failure to complete the Merger by that time is due to
   a violation of the Merger Agreement by the party that wants to terminate the
   Merger Agreement

Regardless of whether the Merger is completed, each of us will pay our own fees
and expenses.   DTG will pay for the printing and mailing of this document.
McLeodUSA will pay the registration and filing fees due to the SEC and The
Nasdaq Stock Market.

If DTG terminates the Merger Agreement due to a competing acquisition offer that
is received by DTG, DTG would be required to pay McLeodUSA $500,000.  In
addition, if a competing acquisition offer is accepted and completed within one
year of the termination of the Merger Agreement on this basis, then DTG would be
required to pay to McLeodUSA an additional $2,000,000.  If a competing
acquisition offer is not completed within one year of the termination of the
Merger Agreement, then DTG would be required to either pay McLeodUSA $2,000,000
or issue to McLeodUSA 200,000 shares of DTG Common Stock, at DTG's option.
These termination fees could discourage other companies from making competitive
bids to combine with DTG before the Merger is completed.  See "Termination Fees"
on page ___.

WAIVER AND AMENDMENT  (PAGE __)

McLeodUSA and DTG may agree to amend the Merger Agreement, except that after DTG
stockholders adopt the Merger Agreement, the parties can't reduce or change the
consideration that will be received by DTG stockholders unless such change is
approved by the DTG stockholders. Either of us can waive our right to require
the other party to adhere to the terms and conditions of the Merger Agreement,
if the law allows, at any time prior to the time the Merger becomes effective.


INTERESTS OF DTG'S DIRECTORS AND OFFICERS IN THE MERGER (PAGE __)

Some of DTG's directors and officers have interests in the Merger that are
different from, or in addition to, their interests as DTG stockholders.  These
interests exist because of employment and other agreements that the directors
and officers have with DTG and rights that they have under benefit and
compensation plans.  Some of DTG's officers and directors have also entered into
or would enter into employment agreements, advisory arrangements or other
agreements or arrangements with McLeodUSA after the Merger.  The Merger
Agreement requires McLeodUSA to indemnify directors and officers of DTG for
events occurring before the Merger, including events that are related to the
Merger Agreement.  Interests of DTG's directors and officers are described under
"Interests of Certain Persons in the Merger" at page __.


DIFFERENCES IN THE RIGHTS OF STOCKHOLDERS (PAGE __)

Upon completion of the Merger, you would become a stockholder of McLeodUSA.
Your rights would then be governed by Delaware law and by
the McLeodUSA Certificate of Incorporation and the McLeodUSA Bylaws, rather than
the DTG Certificate of Incorporation and the DTG Bylaws.  Your rights as a
stockholder of McLeodUSA would

differ from your rights as a stockholder of DTG. To review these differences in
more detail, see "McLeodUSA Capital Stock and Comparison of Stockholder Rights"
on page __.


SPECIAL MEETING OF DTG STOCKHOLDERS (PAGE __)

The Special Meeting will be held on ___________,1999 at __________, at the Irene
Public School, 30 E. State Street, Irene, South Dakota 57037.  At the Special
Meeting, you will be asked to vote to adopt the Merger Agreement and to approve
the Merger and the transactions contemplated by the Merger Agreement.

1998. You can vote your shares by attending the meeting and voting in person or

     other nonrecurring operating expenses.  McLeodUSA has included EBITDA data
     because it is a measure commonly used in the industry.  EBITDA is not a
     measure of financial performance under generally accepted accounting
     principles and should not be considered an alternative to net income as a
     measure of performance or to cash flows as a measure of liquidity.

     The following table summarizes certain per share information for McLeodUSA
and DTG on a historical, pro forma combined, and equivalent pro forma basis.
The DTG "equivalent pro forma amounts" are calculated by multiplying the
unaudited pro forma combined per share amounts by 0.4328.  DTG stockholders
would receive 0.4328 shares of McLeodUSA Common Stock in exchange for each share
of DTG Common Stock in the Merger.  The pro forma data do not purport to be
indicative of the results of future operations or the actual results that would
have occurred had the Merger occurred at the beginning of the period presented.
The pro forma financial data have been included in accordance with the rules of
the SEC and are provided for comparative purposes only.

_____________
(1)  Earnings per share were calculated using income (loss) from continuing
     operations. In calculating pro forma earnings per share, no adjustments to
     the pro forma amounts have been made to reflect potential expense
     reductions or revenue enhancements that may result from the Merger or the
     effect of repurchases of McLeodUSA common stock or DTG common stock
     subsequent to the stated period.

(2)  Includes the operations of DTG from January 1, 1998 to September 30, 1998
     and certain adjustments attributable to the March 1998 Senior Note Offering
     and the October 1998 Senior Note Offering as if each had occurred on
     January 1, 1998.

(3)  Includes the operations of CCI and DTG from January 1, 1997 to December 31,
     1997 and certain adjustments attributable to the 1997 Senior Discount Note
     Offering, the 1997 Senior Note Offering, the March 1998 Senior Note
     Offering and the October 1998 Senior Note Offering as if each had occurred
     on January 1, 1997.

(4)  Gives effect to the Merger as if it had occurred at the end of the period.

(5)  The equivalent pro forma computations assume that for each share of DTG
     common stock outstanding, DTG stockholders would receive 0.4328 shares of
     McLeodUSA common stock.

(6)  Calculated by dividing stockholders' equity by the actual number of shares
     of DTG Common Stock outstanding at the end of the periods presented. Shares
     of DTG Common Stock outstanding as of September 30, 1998 and December 31,
     1997 were 2,692,331 and 1,542,348, respectively. If the 395,376 and 911,
     320 shares of DTG Common Stock issuable as of September 30, 1998 and
     December 31, 1997, respectively, to former shareholders Dakota
     Telecommunications Cooperative, Inc. common stock and capital credit
     accounts upon satisfaction by such holders of conditions to issuance were
     considered issued on September 30, 1998 and December 31, 1997, the book
     value per share of DTG Common Stock would have been $1.72 and $3.18,
     respectively.

                                 RISK FACTORS

     You should carefully consider the following risk factors relating to
McLeodUSA and the other information in this Prospectus and Proxy Statement
(including the matters addressed in "Forward-Looking Statements" on page ii),
before you decide whether to approve the Merger Agreement. You should also
consider the additional information set forth in McLeodUSA's SEC Reports on
Forms 10-K, 10-Q and 8-K and in the other documents incorporated by reference in
this Prospectus and Proxy Statement. See "Where You Can Find More Information"
on page __.

LIMITED OPERATING HISTORY; RECENT AND ANTICIPATED LOSSES.

     McLeodUSA began operations in 1992. McLeodUSA's limited operating history
and rapid growth may make it more difficult for you to evaluate its performance.
As a result of expenses related to the expansion of its existing businesses and
strategic acquisitions, McLeodUSA has incurred significant losses. Since January
1, 1995, McLeodUSA's net losses have been as follows:

                    Net Losses
                    ----------
          Period                Amount
          ------                ------

            1995              $11.3 million
            1996              $22.3 million
            1997              $79.9 million
1998 (through Sept. 30)       $93.1 million

McLeodUSA expects to incur significant operating losses during the next several
years while it develops its businesses, expands its fiber optic network and
develops a personal communications system ("PCS") system. If McLeodUSA does not
become profitable in the future, it could have difficulty obtaining funds to
continue its operations. See "--Significant Capital Requirements."

SIGNIFICANT CAPITAL REQUIREMENTS.

     McLeodUSA needs significant capital to continue to expand its operations,
facilities, network and services. As of September 30, 1998, based on McLeodUSA's
current business plan and projections, McLeodUSA estimates that it will require
$1.1 billion through 2001. This estimate includes the projected costs of:

          .    building its fiber optic network, including intra-city fiber
               optic networks
          .    expanding operations in existing and new markets
          .    developing a PCS system
          .    funding general corporate expenses

     McLeodUSA expects to fund these requirements with:

          .    approximately $291.9 million in net proceeds from its October
               1998 debt offering
          .    approximately $402.4 million of cash and investments on hand at
               September 30, 1998
          .    a proposed $100.0 million revolving credit facility
          .    projected operating cash flow

     McLeodUSA cannot assure you that its capital resources will permit it to
fund its planned network deployment and operations or achieve operating
profitability.

     McLeodUSA's estimate of future capital requirements is a "forward-looking
statement" within the meaning of the safe harbor provisions of the Private
Securities Litigation Reform Act of 1995. The actual amount and timing of
McLeodUSA's future capital requirements may differ substantially from its
estimate due to factors such as:

          .    unforeseen delays
          .    cost overruns
          .    engineering design changes
          .    changes in demand for its services
          .    regulatory, technological or competitive developments

                                       12
<PAGE>
 
          .    new opportunities

     McLeodUSA also expects to evaluate potential acquisitions, joint ventures
and strategic alliances on an ongoing basis. McLeodUSA may require additional
financing if it pursues any of these opportunities.

     McLeodUSA may meet any unanticipated capital needs by issuing additional
debt or equity securities or borrowing funds from one or more lenders. McLeodUSA
cannot assure you that it will have timely access to additional financing
sources on acceptable terms. Failure to generate or raise sufficient funds may
require McLeodUSA to delay or abandon some of its expansion plans or
expenditures, which could have a material adverse effect on its business,
results of operations or financial condition.

VARIABILITY OF OPERATING RESULTS.

     McLeodUSA's revenues and operating results may fluctuate significantly from
period to period for many reasons, including:

          .    competition
          .    availability or announcement of alternative technologies
          .    fluctuations in the results of operations of existing business
               units, recently acquired subsidiaries or newly established
               business units
          .    changes in market growth rates for different products and
               services
          .    general economic conditions
          .    significant expenses associated with the construction and
               expansion of its network and services, including the development,
               construction and operation of a PCS system

     These factors and any resulting fluctuations in McLeodUSA's operating
results will make period to period comparisons of its financial condition less
meaningful and could have a material adverse effect on its business, results of
operations and financial condition.

UNCERTAINTIES OF EXPANSION.

     McLeodUSA has rapidly expanded and developed its network and services.
Further expansion and development will depend on a number of factors, including:

          .    cooperation of the incumbent local exchange carriers
          .    regulatory and governmental developments
          .    changes in the competitive climate in which it operates
          .    development of customer billing, order processing and network
               management systems
          .    availability of financing
          .    technological developments
          .    availability of rights-of-way, building access and antenna sites
          .    existence of strategic alliances or relationships
          .    emergence of future opportunities

     McLeodUSA will need to continue to improve its operational and financial
systems and its procedures and controls. McLeodUSA must also grow, train and
manage its employee base. Failure by McLeodUSA to manage its anticipated growth
effectively could have a material adverse effect on its business, results of
operations and financial condition.


RISKS ASSOCIATED WITH ACQUISITIONS.

     As part of its strategy, McLeodUSA has acquired other companies. McLeodUSA
will continue to evaluate additional strategic acquisitions and alliances
principally relating to its current operations. These transactions commonly
involve a number of risks, including:

          .    difficulty assimilating acquired operations and personnel
          .    diversion of management attention
          .    potential disruption of ongoing business
          .    inability to retain key personnel

                                       13
<PAGE>
 
          .    inability to successfully incorporate acquired assets and rights
               into McLeodUSA's service offerings
          .    inability to maintain uniform standards, controls, procedures and
               policies
          .    impairment of relationships with employees, customers or vendors

     Failure to overcome these risks or any other problems encountered in these
transactions could have a material adverse effect on McLeodUSA's business,
results of operations and financial condition.  In connection with these
transactions, McLeodUSA may also issue additional equity securities, incur
additional debt or incur significant amortization expenses related to goodwill
and other intangible assets.


DEPENDENCE ON REGIONAL BELL OPERATING COMPANIES.

     McLeodUSA depends on the Regional Bell Operating Companies ("RBOCs") to
provide most of its core local and some of its long distance services. U S WEST
Communications, Inc. ("U S WEST"), Ameritech Corporation ("Ameritech") and
Southwestern Bell Telephone Company ("SBC") are McLeodUSA's primary suppliers of
local central office switching and local access lines. Their facilities allow
McLeodUSA to provide (1) local service, (2) long distance service and (3)
interexchange private lines. Today, without using these facilities, McLeodUSA
would be unable to provide bundled local and long distance services to most of
its customers, although it could provide stand-alone long distance service to
some customers.

     McLeodUSA's plans to provide additional local services using its own
switches also depend on the RBOCs. In order to interconnect its switches and
other facilities to network elements controlled by the RBOCs, McLeodUSA must
first negotiate and enter into interconnection agreements with them. In August
1996, the Federal Communications Commission ("FCC") released an order (the "FCC
Interconnection Order") implementing the portions of the Telecommunications Act
of 1996 (the "Telecommunications Act") that impose interconnection obligations
on the RBOCs. The U.S. Eighth Circuit Court of Appeals voided certain provisions
of the FCC Interconnection Order. The U.S. Supreme Court reviewed this matter
and is expected to release its decision during the 1998-1999 term. If the U.S.
Supreme Court upholds the decision of the U.S. Eighth Circuit Court of Appeals,
negotiating interconnection agreements could become much more difficult, which
could limit or delay the expansion of McLeodUSA's local exchange switched
services. McLeodUSA cannot assure you that it will succeed in obtaining
interconnection agreements on terms that would permit it to offer local services
at profitable and competitive rates.

     Any successful effort by U S WEST, SBC, Ameritech or other local exchange
carriers to deny or limit McLeodUSA's access to their network elements or
wholesale services would have a material adverse effect on its business, results
of operations and financial condition


U S WEST CENTREX ACTION AND OTHER ACTIONS BY U S WEST.

     On February 5, 1996, U S WEST filed tariffs and other notices with the
public utilities commissions in its fourteen-state service region to limit
future Centrex access to its switches (the "U S WEST Centrex Action"). Centrex
access allows a large customer to aggregate lines, have control over certain
characteristics of those lines and provide a set of standard features on those
lines. Under the terms of the U S WEST Centrex Action, U S WEST would permit
McLeodUSA to use U S WEST's central office switches until April 2005, but would
not allow McLeodUSA to expand to new cities and would severely limit the number
of new lines it could partition onto U S WEST's switches in cities served by
McLeodUSA.

     McLeodUSA has challenged, or is challenging, the U S WEST Centrex Action in
many of the states where McLeodUSA does business or plans to do business.
McLeodUSA has succeeded in blocking the U S WEST Centrex Action in Iowa,
Minnesota, South Dakota, North Dakota and Colorado, although U S WEST could take
further action in some of these states. In Montana, Nebraska and Idaho, however,
similar challenges to the U S WEST Centrex Action have not succeeded. In Wyoming
and Utah, challenges to the U S WEST Centrex Action remain pending before state
regulators.

                                       14
<PAGE>
 
     U S WEST has introduced other measures that may make it more difficult or
expensive for McLeodUSA to use Centrex service. In January 1997, U S WEST
proposed certain interconnection surcharges in several of the states in its
service region. In February 1997, McLeodUSA joined other parties in filing a
petition with the FCC objecting to this proposal based on McLeodUSA's belief
that it violates certain provisions of the Telecommunications Act. The matter
remains pending before the FCC and various state public utilities commissions.

     McLeodUSA anticipates that U S WEST will also pursue legislative
initiatives in states within McLeodUSA's target market area to reduce state
regulatory oversight over its rates and operations. If adopted, these
initiatives could make it more difficult for McLeodUSA to challenge U S WEST's
actions in the future.

     McLeodUSA cannot assure you it will succeed in its challenges to the U S
WEST Centrex Action or other actions by U S WEST that would prevent or deter
McLeodUSA from using U S WEST's Centrex service or network elements. If U S WEST
prevails in any jurisdiction, McLeodUSA may not be able to offer integrated
telecommunications services in that jurisdiction, which could have a material
adverse effect on its business, results of operations and financial condition.


PCS SYSTEM IMPLEMENTATION RISKS.

     McLeodUSA does not own or operate any facilities for providing PCS services
to the public. Developing a PCS system involves a high degree of risk and will
impose significant demands on McLeodUSA's management and financial resources.
McLeodUSA may not succeed in developing a PCS system. Even if McLeodUSA spends
substantial amounts to develop such a system, McLeodUSA may not make a profit
from PCS operations. To implement a PCS system successfully, McLeodUSA must,
among other things:

          .    Select a Digital Protocol. McLeodUSA must choose from among
               several competing and potentially incompatible digital protocol
               technologies. If the digital protocol technology McLeodUSA
               chooses does not become widely employed, McLeodUSA's future
               offering of PCS service could fail.

          .    Build Out its Wireless Infrastructure. FCC rules impose minimum
               PCS buildout and population coverage requirements. If McLeodUSA
               does not comply with these requirements, the FCC could fine
               McLeodUSA or revoke its PCS licenses, even after it has spent
               substantial amounts to develop a PCS system.

          .    Enter Into "Roaming" Arrangements. The success of McLeodUSA's PCS
               system will depend on its ability to enter into "roaming"
               arrangements with other PCS operators throughout the United
               States. McLeodUSA has not entered into any such arrangements and
               cannot assure you that it will be able to do so.

          .    Relocate Fixed Microwave Licensees. To secure a sufficient
               unencumbered PCS spectrum, McLeodUSA may need to move
               approximately 19 microwave licensees to a different spectrum. The
               time and expense of negotiating with and relocating these
               microwave licensees could adversely affect McLeodUSA's proposed
               PCS system.

     McLeodUSA's success in implementing and operating a PCS system will also
depend on a number of factors beyond McLeodUSA's control, including:

          .    changes in communications service rates charged by other
               companies

          .    changes in the supply and demand for PCS services due to
               competition with other wireline and wireless operators in the
               same geographic area

          .    changes in the federal, state or local regulatory requirements
               affecting the operation of PCS systems

          .    changes in PCS or competing wireless technologies that could
               render obsolete the technology and equipment McLeodUSA chooses
               for its PCS system

                                       15
<PAGE>
 
DEPENDENCE ON KEY PERSONNEL.

     McLeodUSA's future success depends on the continued employment of its
senior management team, particularly Clark E. McLeod, McLeodUSA's Chairman and
Chief Executive Officer, and Stephen C. Gray, McLeodUSA's President and Chief
Operating Officer. McLeodUSA does not have term employment agreements with these
employees.

     McLeodUSA believes its success also depends in large part on its ability to
attract, develop, motivate and retain experienced and innovative management. The
loss of the services of key personnel, or the inability to attract additional
qualified personnel, could have a material adverse effect on McLeodUSA's
business, results of operations and financial condition.


NEED TO OBTAIN AND MAINTAIN PERMITS AND RIGHTS-OF-WAY.

     To obtain access to rights-of-way needed to install its fiber optic cables,
McLeodUSA must reach agreements with state highway authorities, local
governments, transit authorities, local exchange carriers, other utilities,
railroads, interexchange carriers and other parties. The loss of any of its
rights-of-way could have a material adverse effect on McLeodUSA's business,
results of operations and financial condition. For example, McLeodUSA may need
to spend significant sums to remove and relocate its facilities.


RAPID TECHNOLOGICAL CHANGES.

     Communications technology is changing quickly. Unexpected developments, or
McLeodUSA's failure to adapt to them, could have a material adverse effect on
McLeodUSA's business, results of operations and financial condition.


CONTROL BY MANAGEMENT AND PRINCIPAL STOCKHOLDERS.

     As of September 30, 1998, IES Investments Inc. ("IES"), MHC Investments
Inc. ("MHC"), Richard A. Lumpkin and various trusts for the benefit of his
family, Clark and Mary McLeod, and McLeodUSA's directors and executive officers
beneficially owned approximately __% of the outstanding McLeodUSA Common Stock.
These stockholders can collectively control management policy and all corporate
actions requiring a stockholder vote, including election of the Board of
Directors. IES, MHC, Mr. Lumpkin and various trusts for the benefit of his
family, and Mr. and Mrs. McLeod have entered into various voting agreements for
the election of directors and other matters. The fact that these stockholders
hold so much McLeodUSA Common Stock could make it more difficult for a third
party to acquire McLeodUSA. McLeodUSA's certificate of incorporation contains
provisions that may have the same effect.


SIGNIFICANT DEBT.

     McLeodUSA has substantial debt. As of September 30, 1998, as adjusted to
reflect McLeodUSA's October 1998 debt offering as if it had occurred on that
date, McLeodUSA had $1.2 billion of long-term debt and $483.7 million of
stockholder's equity. As a result, McLeodUSA expects its fixed charges to exceed
its earnings for the foreseeable future. This amount of debt could adversely
affect McLeodUSA in a number of ways, including:

          .    limiting its ability to obtain necessary financing in the future
          .    limiting its flexibility to plan for, or react to, changes in its
               business
          .    requiring it to use a substantial portion of its cash flow from
               operations to pay debt rather than for other purposes, such as
               working capital or capital expenditures
          .    making it more highly leveraged than some of its competitors,
               which may place it at a competitive disadvantage
          .    making it more vulnerable to a downturn in its business


RESTRICTIVE COVENANTS IMPOSED BY INDENTURES.

     The indentures that govern the terms of McLeodUSA's debt impose operating
and financial restrictions that limit its discretion on certain

                                       16
<PAGE>
 
business matters. These restrictions limit or prohibit McLeodUSA's ability to:

          .    incur additional debt
          .    pay dividends or make other distributions
          .    make investments or other restricted payments
          .    enter into sale and leaseback transactions
          .    create liens
          .    enter into transactions with affiliates or related persons
          .    sell assets
          .    consolidate, merge or sell all or substantially all of its assets

     These restrictions could make it more difficult for McLeodUSA to expand,
finance its operations or engage in other business activities that may be in its
interest.


COMPETITION.

     Wireline Competition. McLeodUSA faces intense competition from incumbent
local exchange carriers, including U S WEST, Ameritech, SBC and GTE. These
companies currently dominate their local telecommunications markets.

     McLeodUSA's long distance services compete with hundreds of other companies
in the long distance marketplace. Three major competitors, AT&T, MCI WorldCom
and Sprint, dominate the long distance market. AT&T, MCI WorldCom and Sprint
have also indicated their intention to offer local telecommunications services,
either directly or in conjunction with competitive access providers or cable
television operators.

     Other competitors may include cable television companies, competitive
access providers, microwave and satellite carriers, wireless telecommunications
providers, teleports, private networks owned by large end-users, and
telecommunications management companies.

     These and other firms may enter the small and mid-sized markets where
McLeodUSA focuses its sales efforts. Many of McLeodUSA's existing and potential
competitors have financial and other resources far greater than those of
McLeodUSA.

     The trend toward business combinations and strategic alliances may
strengthen certain of McLeodUSA's competitors. For example, WorldCom acquired
MCI in September 1998. AT&T acquired Teleport Communications Group Inc. in July
1998, and announced plans in June 1998 to acquire Tele-Communications, Inc. In
addition, merger plans have been announced by:

1)  SBC and Ameritech

2)  BellAtlantic and GTE

U S WEST and Ameritech also announced in May 1998 that each had entered into a
marketing arrangement with Qwest Communications, a long distance company. The
FCC ruled these marketing arrangements violate the Telecommunications Act, but
both U S WEST and Ameritech have appealed this ruling. If these or other
competitors enter into alliances or combinations it could put McLeodUSA at a
significant disadvantage.

     The Telecommunications Act provides the incumbent local exchange carriers
with new competitive opportunities. It will permit the RBOCs, upon the
satisfaction of certain conditions, to offer out-of-region long distance
services to customers in their respective regions. In December 1997, the U.S.
District Court for the Northern District of Texas ruled certain of these
conditions unconstitutional. In September 1998, the U.S. Fifth Circuit Court of
Appeals reversed the District Court decision. In October 1998, the U.S. Supreme
Court announced it would review the matter. If ultimately upheld, the District
Court's decision would permit the RBOCs to offer out-of-region long distance
service without first demonstrating they have opened their local market to
competitors like McLeodUSA. The RBOCs could then duplicate McLeodUSA's strategy
of offering bundled local and long distance services. Additional competition
from the RBOCs could have a material adverse effect on McLeodUSA's business,
results of operations and financial condition.

     Wireless Competition. The wireless telecommunications industry is
experiencing significant technological change. McLeodUSA

                                       17
<PAGE>
 
believes the market for wireless services will expand significantly as:

          .    equipment costs decline
          .    equipment becomes more convenient and functional
          .    wireless services become more diverse
          .    technology improves
          .    new competitors enter the market

McLeodUSA also believes wireless service providers will offer wireline
replacement products that may result in wireless services becoming the
customer's primary means of communication. McLeodUSA expects up to eight
wireless competitors in each of its proposed PCS markets. McLeodUSA could face
additional competition from mobile satellite services.

     Competition with these or other providers of wireless telecommunications
services may be intense. Many of McLeodUSA's potential wireless competitors have
financial and other resources far greater than those of McLeodUSA and have more
experience testing new or improved products and services. In addition, several
wireless competitors operate or plan to operate, through joint ventures and
affiliation arrangements, wireless telecommunications systems that encompass
most of the United States.


SIGNIFICANT GOVERNMENT REGULATION.

     McLeodUSA's facilities and services are subject to federal, state and local
regulation. The FCC has jurisdiction over all of McLeodUSA's facilities and
services to the extent they are used for interstate or international
communications. State regulatory commissions retain jurisdiction over the same
facilities and services to the extent they are used for intrastate
communications. Local governments generally require McLeodUSA to obtain licenses
or permits to install and operate its networks in public rights-of-way.
McLeodUSA's proposed wireless system will be subject to varying degrees of
regulation by the FCC, state regulatory commissions and local governments.
McLeodUSA's direct marketing, telemarketing and fund-raising activities are also
subject to federal and state regulatory requirements. Any of the following could
have a material adverse effect on McLeodUSA's business, results of operations
and financial condition:

          .    failure to maintain proper federal and state tariffs
          .    failure to maintain proper state certifications
          .    failure to comply with federal, state or local laws and
               regulations
          .    failure to obtain and maintain required licenses and permits
          .    burdensome license or permit requirements to operate in public
               rights-of-way
          .    burdensome or adverse regulatory requirements


VOLATILITY OF STOCK PRICE.

     The market price of McLeodUSA Common Stock is extremely volatile and has
fluctuated over a wide range. From January 1, 1998 to November 30, 1998, the
McLeodUSA Common Stock has traded as high as $48.3125 per share and as low as
$15.25 per share. The market price may continue to fluctuate significantly in
response to various factors, including:

          .    low trading volume
          .    quarterly variations in operating results or growth rates
          .    changes in estimates by securities analysts
          .    market conditions in the industry
          .    announcements by competitors
          .    regulatory and judicial actions
          .    general economic conditions

     In addition, the stock market has from time to time experienced significant
price and volume fluctuations unrelated to the operating performance of
particular companies. These fluctuations may continue to affect the stock prices
of high growth companies (such as McLeodUSA) in particular. The market price of
the McLeodUSA Common Stock may decline.


YEAR 2000 DATE CONVERSION.

     McLeodUSA is currently verifying system readiness for the processing of
date-sensitive information by its computerized information systems. The Year
2000 problem impacts 

                                       18
<PAGE>
 
computer programs and hardware timers using two digits (rather than four) to
define the applicable year. Some of McLeodUSA's programs and timers that have
time-sensitive functions may recognize a date using "00" as the year 1900 rather
than 2000, which could result in miscalculations or system failures.

     McLeodUSA is reviewing its information technology ("IT") and non-IT
computer systems and programs to determine which are not capable of recognizing
the Year 2000 and to verify system readiness for the millennium date. The review
includes:

          1.   increasing employee awareness and communication of Year 2000
               issues

          2.   inventorying hardware, software and data interfaces and
               confirming Year 2000 readiness of key vendors

          3.   identifying mission-critical components for internal systems,
               vendor relations and other third parties

          4.   estimating costs for remediation

          5.   estimating completion dates

          6.   correcting/remediating any identified problems

          7.   replacing systems or components that cannot be made Year 2000
               ready

          8.   testing and verifying systems

          9.   implementing the remediation plan

          10.  developing contingency plans

          11.  training for contingency plans

McLeodUSA has completed more than 90% of the activities required for the first
three steps of this review and more than 55% of the activities required for the
fourth and fifth steps. McLeodUSA is in the initial stages of performing the
activities required to complete the remaining steps and has begun to develop
contingency plans to handle its most reasonably likely worst case Year 2000
scenarios.

     McLeodUSA estimates that its Year 2000 readiness costs will not exceed
$11.5 million. McLeodUSA generally expenses these costs as incurred. While
certain costs have been incurred, McLeodUSA has not incurred any material
historical costs for remediation. McLeodUSA does not expect these costs to have
a material adverse effect on its financial position, results of operations or
cash flows.

     McLeodUSA's estimate of its Year 2000 readiness costs is a "forward-looking
statement" within the meaning of the safe harbor provisions of the Private
Securities Litigation Reform Act of 1995. Costs, results, performance and
effects of Year 2000 activities described in those forward-looking statements
may differ materially from actual costs, results, performance and effects in the
future due to the interrelationship and interdependence of McLeodUSA's computer
systems and those of its vendors, material service providers, customers and
other third parties.

     McLeodUSA has not yet fully identified its most reasonably likely worst
case Year 2000 scenarios. McLeodUSA continues to contact its vendors, suppliers
and third parties with which it has material relationships, regarding their
state of readiness. This activity is focused primarily on mission critical
systems and key business suppliers. Until McLeodUSA has received and analyzed
substantial responses from them it will have difficulty determining its worst
case scenarios.

     McLeodUSA has begun to develop contingency plans to handle worst case
scenarios, to the extent they can be identified fully. McLeodUSA intends to
complete its contingency planning after completing its determination of worst
case scenarios. Completion of these activities depends upon the responses to the
inquiries McLeodUSA has made of its major vendors, material service providers
and third parties with which it has material relationships. McLeodUSA has also
begun work on contingency plans for certain systems identified as critical to
its operations.

     If McLeodUSA, its major vendors, its material service providers or its
customers fail to address Year 2000 issues in a timely manner, such failure
could have a material adverse effect on McLeodUSA's business, results of
operations and financial condition. McLeodUSA depends on local exchange
carriers, primarily the RBOCs, to provide most of its local and some of its long
distance services. To the extent Ameritech, SBC or U S WEST fail to address Year
2000 issues which might interfere with their ability to fulfill their

                                       19
<PAGE>
 
obligations to McLeodUSA, such interference could have a material adverse effect
on McLeodUSA's future operations. If other telecommunications carriers are
unable to resolve Year 2000 issues, it is likely that we will be affected to a
similar degree as others in the telecommunications industry.


PROHIBITION ON DIVIDENDS.

     The indentures governing McLeodUSA's debt prohibit McLeodUSA from paying
cash dividends. Consequently, McLeodUSA does not anticipate paying any dividends
for the foreseeable future.

                                       20

PROXIES

     The accompanying form of proxy is for use at the Special Meeting if a DTG
stockholder cannot or does not wish to attend and vote in person.  You may
revoke your proxy at any time before it is exercised, by submitting to the
Corporate Secretary of DTG written notice of revocation or a properly executed
proxy with a later date, or by attending the Special Meeting and voting in
person.  Written notices of revocation and other communications with respect to
the revocation of proxies should be addressed to Dakota Telecommunications
Group, Inc., P.O. Box 66, 29705 453rd Ave., Irene, South Dakota 57037-0066,
Attention: Corporate Secretary.  All shares represented by valid proxies
received, and not revoked before they are exercised, will be voted in the manner
specified in such proxies.  If no specification is made, such shares will be
voted in favor of the adoption of the Merger Agreement and approval of the
Merger and the transactions contemplated by the Merger Agreement.

     The DTG Board is not currently aware of any other matters which will come
before the Special Meeting.  If any other matter should be presented at the
Special Meeting for action, the persons named in the accompanying proxy card
will vote the proxy in their own discretion.

     DTG STOCKHOLDERS SHOULD NOT SEND ANY STOCK CERTIFICATES WITH THEIR PROXY
CARDS.

SOLICITATION OF PROXIES

     DTG will bear the entire cost of soliciting proxies from the DTG
stockholders including the printing costs of this Prospectus and Proxy Statement
and related materials.  In addition to solicitation of the proxies by mail, DTG
will request banks, brokers and other record holders to send proxies and proxy
material to the beneficial owners of DTG Common Stock and secure their voting
instructions.  DTG will reimburse such record holders for their reasonable
expenses in so doing.  DTG intends to use several of its officers and regular
employees, who will not be specially 

                                       21
<PAGE>
 
compensated, to solicit proxies from stockholders, either personally or by
telephone, telegram, facsimile or electronic or United States mail.

RECORD DATE AND VOTING RIGHTS

     Pursuant to the provisions of the Delaware General Corporation Law (the
"DGCL") and the bylaws of DTG (the "DTG Bylaws"), holders of record of shares of
DTG Common Stock at the close of business on ___________, 1998 will be entitled
to notice of and to vote at the Special Meeting (the "Record Date").  __________
shares of DTG Common Stock are entitled to vote at the Special Meeting.  On the
Record Date, there were approximately __________ record holders of DTG Common
Stock.

     Each share of DTG Common Stock entitles its holder to one vote.  The
affirmative vote of a majority of the outstanding shares of DTG Common Stock is
required to adopt the Merger Agreement and approve the transactions contemplated
thereby.

     Shares of DTG Common Stock present in person at the Special Meeting but not
voting, and shares of DTG Common Stock for which DTG has received proxies but
with respect to which holders of such shares have abstained, will be counted as
present at the  Special Meeting for purposes of determining the presence of a
quorum for transacting business.  Certain brokers who hold shares of DTG Common
Stock in nominee or "street" name for customers who are the beneficial owners of
such shares are prohibited from giving a proxy to vote shares held for such
customers with respect to the matters to be voted upon at the Special Meeting
without specific instructions from such customers.  Shares represented by
proxies returned by a broker holding such shares in "street" name will be
counted for purposes of determining whether a quorum exists, even if such shares
are not voted in matters where discretionary voting by the broker is not allowed
("broker non-votes").

     BECAUSE ADOPTION OF THE MERGER AGREEMENT AND APPROVAL OF THE TRANSACTIONS
CONTEMPLATED THEREBY REQUIRES THE AFFIRMATIVE VOTE OF THE HOLDERS OF A MAJORITY
OF THE OUTSTANDING SHARES OF DTG COMMON STOCK, ABSTENTIONS AND BROKER NON-VOTES
WILL HAVE THE SAME EFFECT AS VOTES AGAINST ADOPTION OF THE MERGER AGREEMENT.
ACCORDINGLY, THE DTG BOARD URGES ALL STOCKHOLDERS TO COMPLETE, DATE AND SIGN THE
ACCOMPANYING PROXY AND RETURN IT PROMPTLY IN THE ENCLOSED ENVELOPE.

     All of the members of the DTG Board and certain executive officers of DTG
have entered into voting agreements with McLeodUSA pursuant to which such
persons have agreed to vote their shares in favor of the Merger Agreement and
against any competing transaction.  The _____ shares of DTG Common Stock subject
to these agreements represent approximately ___% of the outstanding shares of
DTG Common Stock.

     For additional information about beneficial ownership of DTG Common Stock
by stockholders owning more than 5% of the DTG Common Stock and by directors and
executive officers of DTG, see "Security Ownership of Certain Beneficial Owners
and Management of DTG."

RECOMMENDATION OF DTG BOARD

     The DTG Board has determined that the Merger is fair to DTG and its
stockholders and is in the best interests of DTG and its stockholders, and,
therefore, has approved the Merger Agreement.  THE DTG BOARD UNANIMOUSLY
RECOMMENDS THAT THE STOCKHOLDERS OF DTG VOTE FOR ADOPTION OF THE MERGER
AGREEMENT.  See "The Merger--Recommendation of the DTG Board and Reasons for the
Merger."

                                  THE MERGER


GENERAL

     The Board of Directors of McLeodUSA (the "McLeodUSA Board"), the DTG Board
and the Board of Directors of Merger Sub have each unanimously approved the
Merger Agreement, which provides for the merger of Merger Sub with and into DTG,
with DTG as the surviving corporation in the Merger (the "Surviving
Corporation"). Each share of DTG Common Stock outstanding immediately prior to
the Merger (other than shares owned by DTG, McLeodUSA or any direct or indirect
wholly owned subsidiary of McLeodUSA or of DTG) would be converted into the
right to receive a number shares of McLeodUSA Common Stock equal to the Exchange
Ratio (as discussed below). Fractional shares of McLeodUSA Common Stock will not
be issued in connection with the Merger, and DTG stockholders otherwise entitled
to a fractional share would be paid in cash for such fractional share, in the
manner described under "Terms of the Merger Agreement and Related Transactions--
Exchange of Certificates; Fractional Shares."

BACKGROUND OF THE MERGER

     In early June 1998, Craig A. Anderson, President and Chief Financial
Officer of DTG, received a telephone call from Steve Gray, President and Chief
Operating Officer of McLeodUSA, in which Mr. Gray suggested that they meet to
discuss areas of mutual interest in the development of advanced fiber optic
networks in South Dakota and the surrounding states.  Messrs. Anderson and Gray
agreed to schedule a meeting for June 24, 1998 in DTG's offices in Sioux Falls,
South Dakota.  Prior to this time, DTG and McLeodUSA had entered into a joint
construction agreement for the construction of fiber optic cables in and around
Sioux Falls.

     On June 24, 1998, Mr. Gray, J. Lyle Patrick, Executive Vice President and
Chief Financial Officer of McLeodUSA, and John Wray, Senior Vice President for
Corporate Development of McLeodUSA, met with Mr. Anderson and Thomas W. Hertz,
Chairman of the Board and Chief Executive Officer of DTG, at DTG's offices in
downtown Sioux Falls.  At the meeting, the common regional focus and strategies
of both companies were discussed and the possible synergistic advantages of a
business combination between DTG and McLeodUSA were first introduced.  At the
conclusion of the meeting, the parties agreed that it was desirable to pursue
further discussions concerning a possible business combination.

     On June 25, 1998, the parties entered into a confidentiality agreement.
Later that day, Mr. Anderson sent Mr. Wray a copy of certain financial
information concerning DTG.

     On June 30, 1998, at a regularly scheduled meeting of the DTG Board,
Messrs. Anderson and Hertz informed the Board of their June 24, 1998 meeting and
the interest expressed by McLeodUSA in pursuing a possible business combination
with DTG.  The DTG Board authorized Messrs. Anderson and Hertz to proceed with
further discussions with McLeodUSA.

     From July 17, 1998 through July 27, 1998, numerous discussions ensued
between Mr. Anderson and various representatives of McLeodUSA concerning the
respective companies' business plans, strategies and financial results.

     On July 28, 1998, at a regularly scheduled meeting of the DTG Board, Mr.
Anderson reported to the Board on his various discussions with McLeodUSA
representatives.  Following significant discussions, the DTG Board again
authorized Messrs. Anderson and Hertz to proceed with further discussions with
McLeodUSA.

     On August 3, 1998, Mr. Hertz traveled to McLeodUSA's corporate offices in
Cedar Rapids, Iowa, to meet with Clark McLeod, McLeodUSA's Chairman, and Messrs.
Gray, Patrick and Wray. At that meeting, the parties reaffirmed the common
development plans of the two companies and discussed in greater detail the
synergistic fit of DTG as part of McLeodUSA.

     On August 7, 1998, in response to the various issues raised in the August
3, 1998 meeting, Mr. Anderson sent a lengthy memorandum to Messrs. Gray, Wray
and Patrick summarizing DTG's view of how a potential business combination might
proceed.  On August 14, 1998, in a meeting at DTG's offices in Sioux Falls,
Messrs. Anderson and Hertz met with Messrs. Gray, Patrick and Wray to review Mr.
Anderson's memorandum and to discuss certain structural issues.

     On August 19, 1998, Mr. Anderson sent a memorandum to the DTG Board
summarizing the ongoing discussions with McLeodUSA.  That same day, at a meeting
of the Strategic Planning Committee of the DTG Board, Messrs. Anderson and Hertz
reviewed with the committee various issues concerning a potential business
combination with McLeodUSA.  These issues were again discussed at the regularly
scheduled meeting of the DTG Board on August 25, 1998.  At that meeting, DTG's
outside legal counsel also discussed with the DTG Board various legal and other
issues relating to a possible business combination with McLeodUSA, as well as
various publicly available information on McLeodUSA.  Again, the DTG Board
directed DTG's executive management to proceed with further discussions with
McLeodUSA.

     On August 26, 1998, Mr. Anderson received a detailed request for documents
and other information from McLeodUSA to assist McLeodUSA in its review and
analysis of DTG.  The requested information was compiled and submitted to
McLeodUSA on September 14, 1998.

     On September 11, 1998, DTG received a draft of a proposed merger agreement
from McLeodUSA.  Review of this draft agreement led to a series of discussions
between Mr. Anderson and Mr. Wray concerning various significant transaction
issues.  On September 24, 1998, Mr. Hertz called Mr. Gray to discuss various
open issues, and the parties agreed to meet in Cedar Rapids to discuss these
issues in detail.

     On September 28, 1998, Mr. Hertz and William Heaston, DTG's General
Counsel, met with Messrs. Gray, Wray and Patrick in Cedar Rapids to discuss
certain issues raised by the draft merger agreement. Also in attendance at this
meeting were Randall Rings, General Counsel for McLeodUSA, and Tracy Larsen of
Warner Norcross & Judd LLP, outside legal counsel to DTG. Mr. Anderson
participated in the meeting by telephone. Extensive discussions took place at
this meeting.

     On September 29, 1998, at a regularly scheduled meeting of the DTG Board,
Messrs. Anderson, Hertz and Heaston reported to the Board on the results of the
due diligence review process and their ongoing discussions with the McLeodUSA
representatives.  Mr. Larsen also reviewed the terms of the draft merger
agreement with the DTG Board, and summarized the status of ongoing negotiations.
The DTG Board discussed possible advantages of a business combination with
McLeodUSA, as well as various strategic alternatives.  The DTG Board again
directed DTG's executive management to proceed with further negotiations with
McLeodUSA, and authorized the engagement of Duff & Phelps, LLC ("Duff &
Phelps"), a nationally recognized investment banking firm, to render an opinion
as to the fairness from a financial point of view of any offer which might be
forthcoming from McLeodUSA.  Duff & Phelps accepted such engagement and
commenced its independent analysis of DTG.

     Significant negotiations and discussions ensued between DTG and McLeodUSA
and their respective legal counsel on the terms of the proposed merger
agreement.

     On October 6, 1998, representatives of McLeodUSA performed an environmental
survey of DTG's properties.  The following week McLeodUSA representatives met
with various representatives of DTG at DTG's facilities to review DTG and its
operations.

     On October 10, 1998, at a special meeting, the DTG Board met with outside
legal counsel to discuss the status of a possible business combination with
McLeodUSA, as well as various strategic alternatives.  At that meeting, the DTG
Board also met with independent financial advisors and reviewed a proposal
concerning the possible private placement of $20 million of preferred stock to
an institutional investor or investors.

     Extensive negotiations continued between the parties concerning the terms
of a possible business combination between DTG and McLeodUSA.

     During the evening of October 27, 1998, the parties resolved all
substantive terms of the Merger Agreement, and the DTG Board convened to
consider the terms of the Merger Agreement.  At this meeting, Duff & Phelps
delivered its opinion to the DTG Board to the effect that the proposed merger
was fair from a financial point of view, and the DTG Board unanimously approved
the Merger Agreement and the Merger. Later that night, the parties signed the
Merger Agreement.

     On the morning of October 28, 1998, before the opening of The Nasdaq Stock
Market, a joint press release was issued by McLeodUSA and DTG announcing the
execution of the Merger Agreement and the transactions contemplated by the
Merger Agreement.

     DTG and McLeodUSA also entered into a 20-year dark fiber lease agreement
with an aggregate value of $5 million paid by McLeodUSA in advance on October
28, 1998. Revenues under this agreement will be reported on a deferred basis,
resulting in additional revenues in 1998 of approximately $42,000 and
approximately $250,000 per year for the remainder of the lease term.

RECOMMENDATION OF THE DTG BOARD AND REASONS FOR THE MERGER

     THE DTG BOARD BELIEVES THAT THE MERGER IS FAIR TO, AND IN THE BEST
INTERESTS OF, DTG AND DTG STOCKHOLDERS.  ACCORDINGLY, THE DTG BOARD HAS
UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND UNANIMOUSLY RECOMMENDS THAT DTG
STOCKHOLDERS VOTE FOR THE ADOPTION OF THE MERGER AGREEMENT AND THE APPROVAL OF
THE MERGER AND THE TRANSACTIONS CONTEMPLATED BY THE MERGER AGREEMENT.

     In making its decision to approve the Merger Agreement and to recommend to
the holders of DTG Common Stock that they vote their shares in favor of adoption
of the Merger Agreement, the DTG Board considered a number of factors,
including, among others, the following material considerations:

     (i)    The directors' familiarity with and review of the business,
financial condition and result of operations of DTG, DTG's competitive position
in its business, and other financial information and general economic
conditions;

     (ii)   The advantages of a strategic combination with McLeodUSA in
enhancing DTG's product and service offerings, growth prospects and competitive
position;

     (iii)  The possible alternatives to the Merger including, among others,
continuing to operate DTG as an independent entity and the associated risks;

     (iv)   The historical values of DTG Common Stock relative to the value
represented by the consideration to be received in the Merger;

     (v)    The anticipated costs associated with pursuing other strategic
alternatives;

     (vi)   The directors' belief that the consideration payable in the Merger
represented the highest value per share that could be negotiated with McLeodUSA;

                                       25
<PAGE>
 
     (vii)  The presentation by Duff & Phelps, including the opinion of Duff &
Phelps to the effect that the proposed merger is fair to the DTG stockholders
from a financial point of view;
 
     (viii) The timing of the transaction and premiums currently reported to be
obtained in comparable transactions;

     (ix)   That shares of McLeodUSA Common Stock are traded on The Nasdaq
Stock Market while there is no established market for shares of DTG Common
Stock;

     (x)    The proposed structure of the transaction, including its tax-free
nature;

     (xi)   The terms and conditions of the Merger Agreement, including, among
others, the right of the DTG Board (i) in connection with the discharge of its
fiduciary duties to DTG and its stockholders, to withdraw, modify or amend its
recommendation to the stockholders to accept the Merger and pursue a competing
transaction with another party, and (ii) in certain circumstances to terminate
the Merger Agreement, and the financial consequences of such termination; and

     (xii)  The financial condition of McLeodUSA.

     The DTG Board also recognized that holders of DTG Common Stock will be
entitled to receive shares of McLeodUSA Common Stock in the Merger, and that
this would allow such holders the opportunity to participate in the benefits, if
any, of increases in the value of McLeodUSA's business and properties following
the Merger.  Accordingly, the DTG Board gave consideration to McLeodUSA's future
prospects, as well as its historical results of operations.

     The DTG Board did not assign relative weights to the foregoing factors or
determine that any factor was of specific importance relative to any other
factor.  Rather, the DTG Board viewed its position and recommendation as being
based on the totality of the information presented to it and considered by it.

     The full text of the opinion of Duff & Phelps dated as of October 27, 1998
is attached to this Prospectus and Proxy Statement and is incorporated herein by
reference.  A description of the assumptions made, matters considered, analyses
used and limitations on the review undertaken by Duff & Phelps in connection
with the opinion is set forth below under the caption "Opinion of DTG's
Financial Advisor."  STOCKHOLDERS ARE URGED TO READ THE OPINION AND THE RELATED
DESCRIPTION IN THEIR ENTIRETY.  The DTG Board was aware that Duff & Phelps would
be entitled to receive certain fees described under "Opinion of DTG's Financial
Advisor" in connection with rendering its opinion, regardless of the conclusions
reached and regardless of whether the Merger is consummated.


OPINION OF DTG'S FINANCIAL ADVISOR

     Duff & Phelps has rendered a written opinion to the DTG Board to the effect
that, as of October 27, 1998, the proposed Merger is fair to the stockholders of
DTG from a financial point of view.  Duff & Phelps' opinion is attached as
Appendix B and is incorporated herein by reference.  HOLDERS OF DTG COMMON STOCK
ARE ENCOURAGED TO READ THIS OPINION IN ITS ENTIRETY.

     Pursuant to an agreement dated September 29, 1998 (the "Duff & Phelps
Agreement"), Duff & Phelps was engaged by the DTG Board to render an opinion as
to whether the proposed Merger was fair to the stockholders of DTG from a
financial point of view.  In rendering the opinion, it was Duff & Phelps'
understanding that DTG was considering a proposed Merger wherein DTG would be
acquired by McLeodUSA, and each share of DTG Common Stock would be exchanged for
0.4328 shares of McLeodUSA Common Stock (the "Exchange Ratio").  Duff & Phelps
further understood

                                       26
<PAGE>
 
that the proposed Merger would be submitted to the stockholders of DTG for
adoption at the Special Meeting.

     Duff & Phelps is a nationally recognized investment banking firm that is
regularly engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, private placements and valuations for
corporate and other purposes.  The DTG Board retained Duff & Phelps as its
financial advisor on the basis of Duff & Phelps' familiarity with DTG and the
telecommunications industry, its reputation and qualifications, as well as its
experience and expertise in transactions similar to the proposed Merger.  Duff &
Phelps has previously provided financial advisory services to the trustee of
DTG's Employee Stock Ownership Plan.  No limitations were imposed by the DTG
Board upon Duff & Phelps with respect to the investigations made or procedures
followed by Duff & Phelps.

     Duff & Phelps' opinion is directed to the DTG Board only and is directed
only to the fairness of the proposed Merger to the stockholders of DTG from a
financial point of view and does not constitute a recommendation to any of DTG's
stockholders as to how they should vote on any matter at the Special Meeting.
The analysis of the fairness of the Merger assumes that the transaction takes
place on the terms described in the Merger Agreement.

     For purposes of its opinion and in connection with its review of the
proposed Merger, Duff & Phelps, among other things:  (i) reviewed a draft dated
as of October 22, 1998 of the Merger Agreement, including drafts of exhibits and
schedules thereto; (ii) discussed the history, current operations and future
outlook of DTG as well as the history and terms of the proposed Merger with DTG
management; (iii) reviewed DTG's Form 10-KSB for the year ended December 31,
1997; (iv) reviewed DTG's Form 10-QSB for the period ended June 30, 1998; (v)
reviewed the DTG CLEC Facilities Expansion Plan dated as of July 1998; (vi)
reviewed a Private Placement Memorandum dated as of May 1998 prepared in
conjunction with a proposed offering of DTG's preferred stock; (vii) reviewed a
1998-2002 Development Forecast dated as of May 1998; (viii) reviewed the market
prices and trading activity of the McLeodUSA Common Stock; (ix) reviewed the
McLeodUSA Form 10-K for the year ended December 31, 1997; (x) reviewed the
McLeodUSA Form 10-Q for the period ended June 30, 1998; and (xi) performed such
other reviews and analyses as Duff & Phelps deemed necessary.

     In connection with Duff & Phelps' opinion, with DTG's permission and
without any independent verification, Duff & Phelps has relied on the accuracy
and completeness of all the financial and other information reviewed by Duff &
Phelps or furnished or otherwise communicated to Duff & Phelps by DTG or
obtained by Duff & Phelps from publicly available sources.  Duff & Phelps has
not made an independent valuation or appraisal of the assets or liabilities of
DTG and has not been furnished with such valuation or appraisal.  Any
inaccuracies in the information on which Duff & Phelps relied could materially
affect its opinion.

     In conjunction with rendering its written opinion dated October 27, 1998 to
the DTG Board, Duff & Phelps presented a summary of its analysis to the DTG
Board on October 27, 1998.  Set forth below is a brief summary of the analyses
performed by Duff & Phelps in reaching its October 27, 1998 opinion.

     VALUE OF PROPOSED TRANSACTION.  Duff & Phelps examined the history of
trading prices and volume for McLeodUSA Common Stock.  Duff & Phelps' analysis
presumed a $30 to $35 per share trading price range for McLeodUSA Common Stock
which implied a $13 to $15 per share price for DTG Common Stock.

     COMPARABLE PUBLIC COMPANY ANALYSIS.  Duff & Phelps compared selected
financial and other operating ratios for DTG to the corresponding ratios of
certain independent local exchange carriers ("ILEC"), competitive local exchange
carriers ("CLEC") and cable companies.  These comparable public companies are
listed in the following table.

     Such ratios included:  revenue, operating cash flow, net income and
earnings per share ("EPS") growth rates; operating cash flow, earnings before
interest and taxes ("EBIT") and net income margins; returns on assets, invested
capital and equity; total debt to total capital; and value to sales, value to
earnings before interest, taxes, depreciation and amortization ("EBITDA"), value
to invested capital, and value to net property plant and equipment ("PPE").  The
statistics were generally based on financial and operating data up to, at or for
the twelve months ended June 30, 1998 and market prices as of October 16, 1998.

     Duff & Phelps compared the typical range of valuation multiples for the
comparable public companies with the valuation multiples for DTG that were
implied by the proposed Merger.  The results of this analysis are summarized in
the following table.

     DISCOUNTED CASH FLOW ANALYSIS.  Duff & Phelps performed a discounted cash
flow analysis of DTG based on the forecasted information provided by DTG's
management.  The projected cash flows and terminal value were discounted to
present values as of October 1998, using discount rates ranging from 15% to 17%,
which reflect different assumptions regarding the required rates of return of
lenders as well as holders and prospective buyers of DTG Common Stock.  The
terminal value of DTG was estimated by applying a range of multiples to DTG's
projected 2003 EBITDA.  The range of present values per fully diluted share of
DTG Common Stock resulting from this analysis was $10 to $13.
 
     LIQUIDATION ANALYSIS.  Duff & Phelps performed a business segment analysis
of DTG based on revenue and customer by business line.  Representative levels of
revenue were based on annualized latest quarter results (June 1998).  Valuation
multiples applied were based on analyst reports, merger transaction data and
other observations.  The range of value per fully diluted share of DTG Common
Stock resulting from this analysis was $7 to $12.

     No company or transaction used in the above analyses is identical to DTG or
the proposed Merger.  Accordingly, an analysis of the results of the foregoing
is not mathematical; rather, it involves complex considerations and judgments
concerning differences in financial and operating characteristics of the
companies and other facts that could affect the public trading value of the
companies to which they are being compared.

     The material analyses performed by Duff & Phelps have been summarized
above. Nonetheless, the summary set forth above does not purport to be a
complete description of the analyses performed by Duff & Phelps.  The
preparation of a fairness opinion involves various determinations as to the most
appropriate and relevant methods of financial analysis and the application of
these methods to the particular circumstances.  Therefore, such an opinion is
not readily susceptible to a summary description.  Duff & Phelps did not form a
conclusion as to whether any individual analysis, considered in isolation,
supported or failed to support an opinion as to fairness.  Rather, in reaching
its conclusion, Duff & Phelps considered the results of the analyses in light of
each other and ultimately reached its opinion based on the results of all
analyses taken as a whole.  Duff & Phelps did not place a particular reliance or
weight on any particular analysis, but instead concluded that its analyses,
taken as whole, supported its opinion.

     In performing its analyses, Duff & Phelps made numerous assumptions with
respect to DTG's performance, general business and economic conditions and other
matters.  The analyses performed by Duff & Phelps are not necessarily indicative
of future actual values or future results, which may be significantly more or
less favorable than suggested by such analyses.  The analyses do not purport to
be appraisals or to reflect prices at which a company might actually be sold or
the prices at which any securities may trade at the present time or at any time
in the future.  Duff & Phelps used in its analyses various projections of future
performance prepared by the management of DTG.  The projections were based on
numerous variables and assumptions which are inherently unpredictable and must
be considered not certain of occurrence as projected.  Accordingly, actual
results could vary significantly from those assumed in the projections and any
related analyses.  Duff & Phelps' opinion does not address the relative merits
of the proposed Merger as compared to any alternative business strategies that
might exist for DTG or the effect of any other business combination in which DTG
might engage.

     Pursuant to the terms of the Duff & Phelps Agreement, DTG has agreed to pay
Duff & Phelps a fee of $90,000 for financial advisory services in connection
with the proposed Merger, including the rendering of its opinion. DTG has also
agreed to reimburse Duff & Phelps for reasonable out-of-pocket expenses and to
indemnify Duff & Phelps against certain expenses and liabilities incurred in
connection with the performance of its duties under the Duff & Phelps Agreement.

     Duff & Phelps' opinion to the DTG Board was one of many factors taken into
consideration by the DTG Board in making its determination to approve the
proposed Merger.  See "Recommendation of the DTG Board and Reasons for the
Merger," on page__.

1998, WHICH SETS FORTH, AMONG OTHER THINGS, ASSUMPTIONS MADE, MATTERS CONSIDERED
AND LIMITS ON THE REVIEW UNDERTAKEN BY DUFF & PHELPS, IS ATTACHED TO THIS
PROSPECTUS AND PROXY STATEMENT AS APPENDIX B, AND IS INCORPORATED HEREIN BY

ENTIRETY.  THE SUMMARY SET FORTH IN THIS PROSPECTUS AND PROXY STATEMENT OF THE
OPINION OF DUFF & PHELPS IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL
TEXT OF THE OPINION ATTACHED HERETO.


INTERESTS OF CERTAIN PERSONS IN THE MERGER

     Certain members of DTG's management and the DTG Board may be deemed to have
certain interests in the Merger that are in addition to their interests as DTG
stockholders generally. The DTG Board was aware of these interests and
considered them, among other matters, in approving the Merger Agreement and the
transactions contemplated thereby. 

                                       29

     EMPLOYMENT AGREEMENTS.  It is expected that, at the time the Merger
becomes effective (the "Effective Time"), McLeodUSA would enter into employment
agreements ("Employment Agreements") with Thomas W. Hertz, Chairman and Chief
Executive Officer of DTG, Craig A. Anderson, President, Chief Financial Officer
and Treasurer of DTG, William Heaston, Assistant Secretary and General Counsel
of DTG, and Paul Blide, Executive Vice President and Chief Operating Officer of
DTG.

     Mr. Hertz's Employment Agreement would provide that he would be employed
following the Effective Time of the Merger on an "at will" basis as Vice
President of McLeodUSA and McLeodUSA Telecommunications Services, Inc., a wholly
owned subsidiary of McLeodUSA ("MTSI"), and as Chairman and Chief Executive
Officer of DTG. Mr. Hertz's base salary would be $120,000 per year. In addition,
Mr. Hertz would receive a bonus of $60,000 for the year ending December 31,
1999, determined in accordance with McLeodUSA's bonus program and, upon signing
his Employment Agreement, Mr. Hertz would be entitled to receive as a bonus
25,000 restricted shares of McLeodUSA Common Stock. Furthermore, Mr. Hertz's
Employment Agreement would provide that he would be granted options ("Initial
Options") to acquire 45,000 shares of McLeodUSA Common Stock not later than 10
days after he signs his Employment Agreement and that he would be granted
options ("Subsequent Options") to acquire 25,000 shares of McLeodUSA Common
Stock on each of the first, second and third anniversaries of his Employment
Agreement. Mr. Hertz's Initial Options would vest at the rate of 20% on each of
the first five anniversaries of such grants and his Subsequent Options would
vest at the rate of 25% on each of the first four anniversaries of such grants.
Mr. Hertz's Employment Agreement would also contain confidentiality,
noncompetition and nonsolicitation provisions. McLeodUSA also agreed to honor
indemnification provisions contained in Mr. Hertz's employment agreement with
DTG.

     Mr. Anderson's Employment Agreement would provide that he would be employed
following the Effective Time of the Merger on an "at will" basis as Vice
President of McLeodUSA and MTSI and as President, Chief Financial Officer and
Treasurer of DTG. Mr. Anderson's base salary would be $120,000 per year. In
addition, Mr. Anderson would receive the same bonuses, Initial Options and
Subsequent Options as would be granted to Mr. Hertz. Mr. Anderson's Employment
Agreement would also contain confidentiality, noncompetition and nonsolicitation
provisions. McLeodUSA also agreed to honor indemnification provisions contained
in Mr. Anderson's employment agreement with DTG.

     Mr. Heaston's Employment Agreement would provide that he would be employed
following the Effective Time of the Merger until February 28, 2001 (the "Initial
Term") as Associate General Counsel of McLeodUSA and as Vice President and
Corporate Counsel of DTG. Upon expiration of the Initial Term, Mr. Heaston's
employment would be on an "at will" basis. Mr. Heaston's base salary would be
$100,000 per year. Mr. Heaston's Employment Agreement would provide that he
would be granted Initial Options to acquire 10,000 shares of McLeodUSA Common
Stock not later than 10 days after he signs the Employment Agreement. Mr.
Heaston's Initial Options would vest at the rate of 25% on each of the first
four anniversaries of such grants. Mr. Heaston's Employment Agreement does not
provide for Subsequent Options. Mr. Heaston's Employment Agreement would also
contain confidentiality, noncompetition and nonsolicitation provisions.

     Mr. Blide's Employment Agreement would provide that he would be employed on
an "at will" basis following the Effective Time of the Merger as Vice President
of McLeodUSA and MTSI and as Executive Vice President of DTG. Mr. Blide's base
salary would be $110,000 per year. In addition, Mr. Blide would receive a bonus
of $30,000 for the year ending December 31, 1999. Mr. Blide's Employment
Agreement would provide that he would be granted Initial Options to acquire
20,000 shares of McLeodUSA Common Stock not later than 10 days after he signs
the Employment Agreement and that he would be granted Subsequent Options to
acquire 10,000 shares of McLeodUSA Common Stock on the first anniversary of his
Employment Agreement. Mr. Blide's Initial Options would vest at the rate of 20%
on each of the first five anniversaries of such grants and his Subsequent
Options would vest at the rate of 25% on each of the first four anniversaries of
such

                                       30
<PAGE>
 
grants. Mr. Blide's Employment Agreement would also contain confidentiality,
noncompetition and nonsolicitation provisions.

     The exercise price for all of the Initial Options and Subsequent Options
described above would be established in accordance with McLeodUSA's 1996
Employee Stock Option Plan to be the higher of the fair market value of the
shares of McLeodUSA Common Stock on the trading day immediately preceding the
grant date or the average trading value of such stock during the 30 trading days
immediately preceding the grant date. All options will be subject to the terms
of McLeodUSA's 1996 Employee Stock Option Plan.

     BONUSES.  Upon consummation of the Merger, the officers and employees of
DTG will be paid bonuses not to exceed $500,000 in the aggregate. Mr. Hertz and
Mr. Anderson will not participate in these bonuses. The allocation of the bonus
pool among DTG officers and employees has not yet been determined.

     ADVISORY COMMITTEE COMPENSATION.  As discussed in "Terms of the Merger
Agreement and Related Transactions--Management After the Merger" on page ___,
McLeodUSA and DTG have agreed that following the Effective Time an advisory
committee will be established by and provide certain consulting services to the
Board of Directors of the Surviving Corporation at its request and direction.
Each person accepting such a position on the advisory committee, which generally
will consist of the current members of the DTG Board and Edward D. Christiansen,
Jr., would receive as compensation (1) a one-time grant of an option to purchase
2,000 shares of McLeodUSA Common Stock with such option vesting at a rate of 25%
per year and (2) a quarterly fee of $2,000, plus reimbursement for reasonable
out-of-pocket travel expenses incurred in connection with service on the
advisory committee.  In addition, each member of the advisory committee will be
entitled to participate, at such member's expense, in the medical and health
insurance plans of the Surviving Corporation as in effect from time to time, to
the extent permitted by the terms of such plans.  DTG and McLeodUSA have agreed
that the advisory committee will continue until the fifth anniversary of the
Effective Time unless terminated earlier by decision of McLeodUSA and the
unanimous vote of the advisory committee.

     STOCK-BASED RIGHTS.  Pursuant to the terms of certain DTG stock option
agreements and in connection with the Merger, certain stock options held by
Messrs. Hertz, Anderson, Blide and Heaston will become fully vested and
exercisable at the Effective Time.  The number of stock options to acquire
shares of DTG Common Stock held by each of Messrs. Hertz and Anderson that will
become fully vested and exercisable as a result of the transactions contemplated
by the Merger Agreement is 140,180 (of which, 123,980 have an exercise price of
$6.19 per share and 16,200 have an exercise price of $12.50 per share).  The
number of stock options to acquire shares of DTG Common Stock held by Messrs.
Blide and Heaston is 10,100 and 5,100, respectively, all of which have an
exercise price of $12.50 per share.  The stock options shall become options to
purchase shares of McLeodUSA Common Stock and the number of shares of McLeodUSA
Common Stock subject to these options will be adjusted for the Exchange Ratio as
discussed in "Terms of the Merger Agreement and Related Transactions--Conversion
of DTG Common Stock and Conversion-Merger Rights; Treatment of Options."

     INDEMNIFICATION; DIRECTORS AND OFFICERS INSURANCE.  McLeodUSA has agreed
that for the period from the Effective Time until at least six years after the
Effective Time, (1) it will cause the Surviving Corporation to maintain and to
honor (including, without limitation, by providing the Surviving Corporation
with sufficient funding) DTG's current directors' and officers' insurance and
indemnification policy and related arrangements, or an equivalent policy and
related arrangements, for all present and former directors and officers of DTG,
covering claims made and insurable events occurring prior to or within six years
after the Effective Time (provided that the Surviving Corporation will not be
required to maintain such policy except to the extent that the aggregate annual
cost of maintaining such policy is not in excess of 200% of the current annual
cost, in which case the Surviving Corporation shall maintain such policies up to
an annual cost of 200% of the current annual cost); and (2) it will cause the
Surviving Corporation to maintain and to honor

                                       31
<PAGE>
 
(including, without limitation, by providing the Surviving Corporation with
sufficient funding) indemnification provisions, including, without limitation,
provisions for expense advances, for present and former officers and directors
in the Surviving Corporation's certificate of incorporation and bylaws and
certain agreements to the fullest extent permitted by Delaware law.  McLeodUSA
has also agreed to, or to cause the Surviving Corporation to, indemnify and hold
harmless, from and after the Effective Time, to the full extent that the
Surviving Corporation would be permitted by applicable law (and as to matters
arising from or relating to the Merger Agreement and the possible change in
control of DTG, to the full extent that McLeodUSA would be permitted under
applicable law), each present or former officer or director of DTG against any
losses, claims, damages, liabilities, costs, expenses (including reasonable
attorneys' fees), judgments, fines and amounts paid in settlement in connection
with any claim, action, suit, proceeding or investigation to which such person
is, or is threatened to be made, a party by reason of the fact that such person
is or was a director, officer, employee or agent of DTG, or is or was serving at
the request of DTG as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other entity, except that
neither DTG nor McLeodUSA or the Surviving Corporation will be liable for any
settlement effected without its prior written consent (which consent may not be
unreasonably withheld).

ACCOUNTING TREATMENT

     The Merger will be accounted for using the purchase method of accounting.
McLeodUSA will be deemed the acquiror for financial reporting purposes. Under
the purchase method of accounting, the purchase price in the Merger is allocated
among DTG assets acquired and DTG liabilities assumed to the extent of their
fair market value, with any excess purchase price being allocated to goodwill.
Due to the size of McLeodUSA relative to the purchase price, the purchase method
of accounting and the related amortization of goodwill will have an immaterial
effect on McLeodUSA's financial statements.

LISTING ON THE NASDAQ STOCK MARKET

     McLeodUSA has agreed to cause the shares of McLeodUSA Common Stock to be
issued in the Merger to be approved for listing on The Nasdaq Stock Market.  It
is a condition to the consummation of the Merger that such shares of McLeodUSA
Common Stock be authorized for listing on The Nasdaq Stock Market, subject to
official notice of issuance.

GOVERNMENTAL AND REGULATORY APPROVALS

     Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended,
and the rules and regulations promulgated thereunder (the "HSR Act") by the FTC,
the Merger may not be consummated until notifications have been given and
certain information has been furnished to the FTC and the Antitrust Division of
the Department of Justice (the "Antitrust Division") and specified waiting
period requirements have been satisfied. McLeodUSA and DTG filed premerger
notification and report forms with the FTC and the Antitrust Division on
November 6, 1998 and were granted early termination of the waiting period by the
FTC on November 19, 1998.

     However, at any time before or after the Effective Time, the Antitrust
Division, the FTC or a private person or entity could seek under antitrust laws,
among other things, to enjoin the Merger or to cause McLeodUSA to divest itself,
in whole or in part, of the Surviving Corporation or of certain businesses
conducted by the Surviving Corporation.  There can be no assurance that a
challenge to the Merger will not be made or that, if such a challenge is made,
McLeodUSA will prevail.  The obligations of McLeodUSA and DTG to consummate the
Merger are subject to the condition that the applicable waiting period under the
HSR Act shall have expired without action by the Antitrust Division or the FTC
to prevent consummation of the Merger.  See "Conditions to Consummation of the
Merger" and "Termination of the Merger Agreement; Effects of Termination."

                                       32
<PAGE>
 
     In connection with the Merger, McLeodUSA will be required to submit
regulatory notices and may be required to take further actions in one or more of
the states in which McLeodUSA and its subsidiaries operate including the 
Minnesota Public Utilities Commission. In some instances, these regulatory
notices and/or actions are required to be filed or taken a specified period in
advance of the Effective Time of the Merger. In addition, while not required,
McLeodUSA intends to provide courtesy notices prior to the Effective Time to
government entities which have issued certain licenses, certifications and
similar telecommunications regulatory approvals to McLeodUSA and its
subsidiaries. McLeodUSA and DTG believe that any material regulatory approvals
will be obtained in the normal course; however, there can be no assurance that
all such approvals will be obtained by the Effective Time. McLeodUSA and DTG are
aware of no other governmental or regulatory approvals required for consummation
of the Merger, other than compliance with applicable federal and state laws
referred to above.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

     The following discussion summarizes the material United States federal
income tax consequences of the Merger to holders of DTG Common Stock who hold
DTG Common Stock as a capital asset (generally, property held for investment)
within the meaning of Section 1221 of the United States Internal Revenue Code of
1986, as amended (the "Code").  This discussion does not address the individual
tax consequences to any holder of DTG Common Stock whose tax consequences may be
affected by such person's individual circumstances, including without limitation
insurance companies, financial institutions, dealers in securities, holders that
are not citizens or residents of the United States, tax-exempt entities and
holders that acquired DTG Common Stock upon the exercise of employee stock
options or otherwise as compensation. The discussion, moreover, does not address
any consequences arising under any state, local or foreign laws. Finally, the
tax consequences to holders of stock options or restricted stock are not
discussed.  The following discussion is based on the Code, the United States
Department of Treasury regulations promulgated thereunder, and administrative
rulings and court decisions as of the date of this Prospectus and Proxy
Statement.  All of the foregoing are subject to change, possibly with a
retroactive effect, and any such change could affect the accuracy of the
following discussion.  No ruling has been or will be sought from the IRS
concerning the tax consequences of the Merger.  Holders of DTG Common Stock are
urged to consult their tax advisors regarding the tax consequences of the Merger
to them, including the effects of United States federal, state, local, foreign
and other tax laws.

     Warner Norcross & Judd LLP, counsel to DTG, has delivered to DTG an
opinion, dated on or about the date of this Prospectus and Proxy Statement, to
the effect that, for United States federal income tax purposes,

     (i)   the Merger will constitute a "reorganization" within the meaning of
Section 368(a) of the Code;

     (ii)  no gain or loss will be recognized by holders of DTG Common Stock
upon the exchange of their DTG Common Stock solely for shares of McLeodUSA
Common Stock pursuant to the Merger, except with respect to cash, if any,
received in lieu of fractional shares of McLeodUSA Common Stock;

     (iii) the aggregate tax basis of the McLeodUSA Common Stock received by
the holders of DTG Common Stock pursuant to the Merger (including fractional
shares of McLeodUSA Common Stock for which cash is received) will be the same as
the aggregate tax basis of the DTG Common Stock exchanged therefor;

     (iv)  the holding period of the McLeodUSA Common Stock in the hands of the
former holders of DTG Common Stock will include the holding period of such
stockholders' DTG Common Stock exchanged therefor pursuant to the Merger; and

                                       33
<PAGE>
 
     (v)   a holder of DTG Common Stock who receives cash in lieu of a
fractional share of McLeodUSA Common Stock will recognize gain or loss equal to
the difference, if any, between such stockholder's tax basis in such fractional
share (as described in clause (iii) above) and the amount of cash received.

     Such opinion assumes that the Merger will take place as described in the
Merger Agreement.  In rendering such opinion, Warner Norcross & Judd LLP has
relied upon certain facts and customary representations contained in
certificates by officers of DTG and McLeodUSA.  This opinion was provided as a
basis for the tax discussion contained in this Prospectus and Proxy Statement
only.  It does not satisfy the conditions in the Merger Agreement that DTG and
McLeodUSA each receive tax opinions from their respective counsel  as of the
Effective Time.

     An opinion of tax counsel does not guarantee favorable tax treatment.
There is a risk that the IRS might determine that DTG and/or holders of DTG
Common Stock must recognize gain or loss for federal income tax purposes in the
Merger.  ACCORDINGLY, HOLDERS OF DTG COMMON STOCK ARE STRONGLY URGED TO CONSULT
WITH THEIR TAX ADVISORS TO DETERMINE THE PARTICULAR UNITED STATES FEDERAL,
STATE, LOCAL, OR FOREIGN INCOME OR OTHER TAX CONSEQUENCES OF THE MERGER TO THEM.

RESTRICTIONS ON RESALES BY AFFILIATES

     The McLeodUSA Common Stock to be issued to DTG stockholders pursuant to the
Merger Agreement will be freely transferable under the Securities Act of 1933,
as amended (the "Securities Act"), except for shares issued to any person who
may be deemed to be an "affiliate" of DTG within the meaning of Rule 145 under
the Securities Act or who will become an "affiliate" of McLeodUSA within the
meaning of Rule 144 under the Securities Act after the Merger. Shares of
McLeodUSA Common Stock received by persons who are deemed to be DTG affiliates
or who become McLeodUSA affiliates may be resold by such persons only in
transactions permitted by the resale provisions of Rule 145 (permitting limited
sales under certain circumstances) or as otherwise permitted under the
Securities Act. Persons who may be deemed to be affiliates of DTG generally
include individuals or entities that, directly or indirectly through one or more
intermediaries, control, are controlled by or are under common control with DTG
and may include certain officers, directors and principal stockholders of DTG.
All DTG stockholders who may be deemed to be affiliates of DTG will be so
advised prior to the Effective Time.

     It is a condition to the consummation of the Merger that McLeodUSA receive
an agreement from each affiliate of DTG prior to the Effective Time (each, an
"Affiliate Agreement"), pursuant to which each such DTG affiliate shall
undertake not to make any sale of McLeodUSA Common Stock received upon
consummation of the Merger in violation of the Securities Act or the rules and
regulations promulgated thereunder. Generally, this will require that such sales
be made in accordance with Rule 145 under the Securities Act, which in turn
requires that, for specified periods, such sales be made in compliance with the
volume limitations, manner of sale provisions and current information
requirements of Rule 144 under the Securities Act.

     The certificates evidencing McLeodUSA Common Stock issued to DTG affiliates
pursuant to the Merger Agreement will bear a legend summarizing the foregoing
restrictions until a sale, transfer or other disposition of such McLeodUSA
Common Stock has been registered under the Securities Act or is made in
compliance with Rule 145 under the Securities Act.

     Persons who are not affiliates of DTG may sell their McLeodUSA Common
Stock without restrictions and without the necessity to deliver this Prospectus
and Proxy Statement.

NO APPRAISAL RIGHTS

     Under the  DGCL, DTG stockholders are not entitled to appraisal rights
pursuant to which such stockholders could dissent from the Merger and obtain
payment for their shares of DTG Common Stock.

            TERMS OF THE MERGER AGREEMENT AND RELATED TRANSACTIONS


     The following summary of the material terms and provisions of the Merger
Agreement is qualified in its entirety by reference to the Merger Agreement.
The Merger Agreement is attached as Appendix A to this Prospectus and Proxy
Statement and is incorporated herein by reference.

GENERAL


     The Merger Agreement provides that Merger Sub will be merged with and into
DTG at the Effective Time.  Pursuant to the Merger Agreement, DTG will become a
wholly owned subsidiary of McLeodUSA.  The DTG Board has unanimously approved
the Merger Agreement and the Merger.  With certain limited exceptions described
below, each share of DTG Common Stock outstanding at the Effective Time will be
converted pursuant to the Exchange Ratio into the right to receive 0.4328 of a
share of McLeodUSA Common Stock.

     In addition, as a result of certain former holders of common stock and
certain former holders of non-allocated capital credit accounts of the Dakota
Cooperative Telecommunications, Inc., a stock-based South Dakota cooperative
association and DTG's predecessor, not exchanging such interests during the
conversion-merger pursuant to which the Cooperative converted to a South Dakota
corporation and then by merger reincorporated in the State of Delaware (the
"Conversion-Merger"), there are currently outstanding certain rights evidenced
by the unexchanged shares of common stock and non-allocated capital credit
accounts of the Cooperative (the "Conversion-Merger Rights") entitling such
former holders to receive shares of DTG Common Stock.  Pursuant to the Merger
Agreement, at the Effective Time, each outstanding Conversion-Merger Right
entitling the holder thereof to receive one share of DTG Common Stock will be
converted pursuant to the Exchange Ratio into the right to receive 0.4328 of a
share of McLeodUSA Common Stock.  The Merger Agreement provides the maximum
number of shares of McLeodUSA Common Stock issuable pursuant to the Merger shall
be 1,295,000.

     This section of the Prospectus and Proxy Statement describes certain
aspects of the Merger, including the material provisions of the Merger
Agreement. Certain capitalized terms used but not defined herein shall have the
meanings ascribed to them in the Merger Agreement.

STRUCTURE OF THE MERGER

     Subject to the terms and conditions of the Merger Agreement and in
accordance with the DGCL, at the Effective Time Merger Sub will merge with and
into DTG.  DTG will continue its corporate existence under the laws of the State
of Delaware under the name "Dakota Telecommunications Group, Inc."  At the
Effective Time, the separate corporate existence of Merger Sub will terminate.
The DTG Certificate of Incorporation will be amended in its entirety to conform
to the certificate of incorporation of Merger Sub and will become the
certificate of incorporation of the Surviving Corporation.  The DTG Bylaws will
be amended in their entirety to conform to the bylaws of Merger Sub and will
become the bylaws of the Surviving Corporation.

MANAGEMENT AFTER THE MERGER

     Immediately following the Effective Time, the Board of Directors of the
Surviving Corporation will be reconstituted to include a total of five
directors.  The initial directors will be:

     Name                Principal occupation
     ----                --------------------
     Clark E. McLeod     Chairman of the Board of Directors and Chief Executive
                         Officer of McLeodUSA

                                       35
<PAGE>
 
     Stephen C. Gray     President and Chief Operating Officer of McLeodUSA
     J. Lyle Patrick     Group Vice President, Chief Financial Officer and 
                         Treasurer of McLeodUSA
     Thomas W. Hertz     Chairman of the Board of Directors and Chief Executive
                         Officer of DTG
     Craig A. Anderson   President and Chief Financial Officer of DTG

Each will hold office in accordance with the certificate of incorporation and
bylaws of the Surviving Corporation.  The initial officers of the Surviving
Corporation will be the officers of DTG immediately prior to the Effective Time,
in each case until their respective successors are duly elected or appointed and
qualified.  Mr. Hertz and Mr. Anderson will become Vice Presidents of McLeodUSA
after the Merger.

     McLeodUSA and DTG have agreed that following the Effective Time an advisory
committee will be established by and provide certain consulting services to the
board of directors of the Surviving Corporation at its request and direction.
McLeodUSA and DTG have further agreed that: (1) those persons serving as members
of the DTG Board as of the date of the Merger Agreement who are also serving as
members of the DTG Board immediately prior to the Effective Time, and (2) Edward
D. Christensen, Jr., will be offered positions on the advisory committee,
provided such individuals do not become employees of McLeodUSA, the Surviving
Corporation or any of McLeodUSA's other subsidiaries following the Effective
Time.  See "The Merger--Interests of Certain Persons in the Merger," on page
___.

     As discussed in "Interests of Certain Persons in the Merger" on page ___,
it is expected that at the Effective Time, McLeodUSA would enter into Employment
Agreements with Messrs. Hertz and Anderson pursuant to which these persons would
become officers of McLeodUSA after the Merger. The following sets forth certain
biographical information concerning Messrs. Hertz and Anderson:

     DTG since April 1998 and a director and Chief Executive Officer of DTG

                                       36
<PAGE>
 
CONVERSION OF DTG COMMON STOCK AND CONVERSION-MERGER RIGHTS; TREATMENT OF
OPTIONS

     At the Effective Time, each issued and outstanding share of DTG Common
Stock, other than shares held in the treasury of DTG, held by McLeodUSA or held
by any direct or indirect wholly owned subsidiary of McLeodUSA or DTG, and each
outstanding Conversion-Merger Right entitling the holder thereof to receive one
share of DTG Common Stock, will be converted into the right to receive a number
of shares of McLeodUSA Common Stock equal to the Exchange Ratio (0.4328),
subject to customary antidilution adjustments as provided in the Merger
Agreement and described below. Because the Exchange Ratio is fixed and because
the market price of McLeodUSA Common Stock is subject to fluctuation, the value
of the shares of McLeodUSA Common Stock that the stockholders of DTG and the
holders of Conversion-Merger Rights will receive in the Merger may increase or
decrease, both before and after the Merger.

     Each share of DTG Common Stock held in the treasury of DTG, held by
McLeodUSA or held by any direct or indirect wholly owned subsidiary of McLeodUSA
or of DTG will be canceled and extinguished at the Effective Time without the
payment of any consideration.  Each share of common stock of Merger Sub issued
and outstanding immediately prior to the Effective Time will be converted into
and exchanged for one share of common stock of the Surviving Corporation.

     If, prior to the Effective Time, the outstanding shares of McLeodUSA
Common Stock are changed into or exchanged for a different number of shares or a
different class as a result of  any stock dividend, subdivision,
reclassification, recapitalization, split, combination or exchange of shares,
the nature of the consideration and the Exchange Ratio will be appropriately and
correspondingly adjusted.

     Each stock option to acquire DTG Common Stock granted under DTG's 1997
Stock Incentive Plan (the "DTG Stock Plan") or granted to certain officers
independent of the DTG Stock Plan (collectively, the "DTG Stock Options") that
is outstanding and unexercised immediately prior to the Effective Time will be
assumed by McLeodUSA and at the Effective Time will become or be replaced by a
stock option to purchase McLeodUSA Common Stock.  In each case, the number of
shares of McLeodUSA Common Stock subject to the new McLeodUSA option will be
equal to the number of shares of DTG Common Stock subject to the DTG Stock
Option multiplied by the Exchange Ratio (and eliminating any fractional share).
The duration and other terms of each such McLeodUSA option (including the option
price per share) will be the same as the prior DTG Stock Option.  The DTG Stock
Plan and the DTG Stock Options granted to certain officers independent of the
DTG Stock Plan will become 100% vested at the Effective Time.

EXCHANGE OF CERTIFICATES; FRACTIONAL SHARES

     McLeodUSA has agreed to deposit with Norwest Bank Minnesota, N.A., or
another bank or trust company selected by McLeodUSA and reasonably acceptable to
DTG (the "Exchange Agent"), as of the Effective Time, for the benefit of the
holders of issued and outstanding shares of DTG Common Stock, certificates
representing the shares of McLeodUSA Common Stock and cash in lieu of any
fractional shares (such certificates and cash, together with any dividends or
distributions with respect thereto, being referred to herein as the "Exchange
Fund") to be issued pursuant to the Merger Agreement in exchange for such
outstanding shares of DTG Common Stock.  McLeodUSA has further agreed to reserve
and keep available out of its authorized and unissued McLeodUSA Common Stock, as
of the Effective Time, for the benefit of the holders of outstanding Conversion-
Merger Rights, the number of shares of McLeodUSA Common Stock that will be
sufficient to permit the exercise and exchange in full of all Conversion-Merger
Rights outstanding immediately prior to the Effective Time.

     Promptly after the Effective Time, the Exchange Agent will mail a letter of
transmittal to each holder of DTG Common Stock or Conversion-Merger Rights. The
letter of transmittal will

                                       37
<PAGE>
 
contain instructions with respect to (1) the surrender to the Exchange Agent of
certificates representing DTG Common Stock and (2) the surrender to McLeodUSA of
certificates or other instruments representing Conversion-Merger Rights.

     YOU SHOULD NOT RETURN DTG COMMON STOCK CERTIFICATES WITH THE ENCLOSED
PROXY NOR SHOULD YOU FORWARD THEM TO THE EXCHANGE AGENT UNLESS AND UNTIL YOU
RECEIVE THE LETTER OF TRANSMITTAL FOLLOWING THE EFFECTIVE TIME.  YOU MAY RETURN
CERTIFICATES OR OTHER INSTRUMENTS REPRESENTING CONVERSION-MERGER RIGHTS TO DTG
PRIOR TO THE EFFECTIVE TIME FOR EXCHANGE FOR DTG COMMON STOCK PURSUANT TO THE
CONVERSION-MERGER, BUT YOU SHOULD NOT FORWARD THEM TO MCLEODUSA UNLESS AND UNTIL
YOU RECEIVE THE LETTER OF TRANSMITTAL FOLLOWING THE EFFECTIVE TIME.

     Until the certificates representing DTG Common Stock and the certificates
or other instruments representing Conversion-Merger Rights are surrendered for
exchange after the Effective Time, holders of such certificates or other
instruments will accrue but will not be paid dividends or other distributions
declared after the Effective Time with respect to McLeodUSA Common Stock into
which their DTG Common Stock or Conversion-Merger Rights have been converted.
When such certificates or other instruments are surrendered, any unpaid
dividends or other distributions will be paid, without interest. Certificates
representing shares of DTG Common Stock and the certificates or other
instruments representing Conversion-Merger Rights presented after the Effective
Time will be canceled and exchanged for the relevant certificate representing
the applicable number of shares of McLeodUSA Common Stock.

     No fractional shares of McLeodUSA Common Stock will be issued to any
holder of DTG Common Stock or Conversion-Merger Rights upon consummation of the
Merger.  For each fractional share that would otherwise be issued, the Exchange
Agent (in the case of holders of DTG Common Stock) or McLeodUSA (in the case of
holders of Conversion-Merger Rights) will pay cash in an amount equal to such
fractional share multiplied by the average closing price of McLeodUSA Common
Stock on The Nasdaq Stock Market for the 10 trading days immediately preceding
the closing date of the Merger (the "Closing Date").  No interest will be paid
or accrue on the cash in lieu of fractional shares payable to such holders.

     Any portion of the Exchange Fund that remains undistributed one year after
the Effective Time will be delivered to McLeodUSA upon demand. Certificates
representing DTG Common Stock must thereafter be surrendered for exchange to
McLeodUSA. Any shares of McLeodUSA Common Stock, any dividends or other
distributions with respect thereto, and any cash in lieu of fractional shares to
which any holder of DTG Common Stock or Conversion-Merger Rights would otherwise
be entitled pursuant to the Merger which remain unclaimed on the fourth
anniversary of the Effective Time (or such earlier date as such property would
otherwise escheat to or become the property of any governmental entity) will, to
the extent permitted by law, become the property of McLeodUSA. None of
McLeodUSA, Merger Sub, DTG or the Exchange Agent will be liable for any shares
of McLeodUSA Common Stock, dividends or distributions with respect thereto, or
cash in lieu of fractional shares delivered to a public official pursuant to any
abandoned property, escheat or similar laws.

     If a certificate representing DTG Common Stock, or a certificate or other
instrument representing Conversion-Merger Rights, has been lost, stolen or
destroyed, the Exchange Agent (in the case of certificates representing DTG
Common Stock) or McLeodUSA (in the case of certificates or other instruments
representing Conversion-Merger Rights) will issue the consideration properly
payable in accordance with the Merger Agreement upon the making of an affidavit
of such loss, theft or destruction by the claimant, and, if required by the
Exchange Agent or McLeodUSA, the posting of a bond as indemnity against any
claim that may be made against McLeodUSA, the Surviving Corporation or the
Exchange Agent with respect to such certificate or instrument.

differences between the rights of the holders of DTG Common Stock, on the one
hand, and holders of

Comparison of Stockholder Rights."

EFFECTIVE TIME

     The Effective Time will be the date and time of the filing of the articles
of merger to be filed with the Secretary of State of the State of Delaware on
the Closing Date.  The Closing Date will occur no later than the fifth business
day after the satisfaction or waiver of the conditions precedent to the Merger
set forth in Article VII of the Merger Agreement.  DTG and McLeodUSA each
anticipate that, if the Merger is approved at the Special Meeting, the Merger
will be consummated during the fiscal quarter ending March 31, 1999.  However,
the consummation of the Merger could be delayed if there is a delay in obtaining
the requisite Third Party Consents (as defined below).  There can be no
assurances as to if or when such consents will be obtained or that the Merger
will be consummated.  If the Merger is not consummated by August 15, 1999
(subject to up to 60 days extension by McLeodUSA or DTG), the Merger Agreement
may be terminated by either McLeodUSA or DTG, unless the failure to consummate
the Merger by such date is due to the willful failure of the party seeking to
terminate the Merger Agreement to fulfill any of its obligations thereunder.
See "--Conditions to Consummation of the Merger."

     DTG has also agreed promptly to take all action necessary in accordance
with the DGCL and the DTG Certificate of Incorporation and the DTG Bylaws to
duly call, give notice of, convene and hold the Special Meeting, and has agreed

Exchange Act of 1934, as amended (the "Exchange Act") in connection with the

     Pursuant to the Merger Agreement, DTG and McLeodUSA have agreed not to, and
not to permit any of their subsidiaries to, knowingly take any action that could
result in any of their respective representations and warranties becoming untrue
or any of the conditions to the Merger not being satisfied. DTG and McLeodUSA
have also agreed to use all reasonable efforts promptly to make all filings
under applicable laws and to obtain all authorizations, permits, consents and
approvals of all third parties and governmental entities necessary or advisable
to consummate the transactions contemplated by the Merger Agreement (the "Third
Party Consents"). DTG and McLeodUSA have agreed to use all reasonable efforts to
take all necessary, proper or appropriate actions to consummate the transactions
contemplated by the Merger Agreement.

NO SOLICITATION BY DTG

     DTG has agreed to, and to use its reasonable best efforts to cause its
directors, and to cause its officers, employees, representatives, agents and
subsidiaries and their respective directors, officers, employees,
representatives and agents to, immediately cease as of the date of the Merger
Agreement any discussions or negotiations with any person with respect to a
Competing Transaction.  DTG has agreed not to, and to cause its subsidiaries not
to, initiate, solicit or encourage (including by way of furnishing information
or assistance), or take any other action to facilitate, any inquiries or the
making of any proposal that constitutes, or may reasonably be expected to lead
to, any Competing Transaction, or enter into discussions or furnish any
information or negotiate with any person or otherwise cooperate in any way in
furtherance of such inquiries or to obtain a Competing Transaction, or agree to
or endorse any Competing Transaction, or authorize any of its directors,
officers, employees, agents or representatives to take any such action; except
that the DTG Board may (1) furnish information to, or enter into discussions or
negotiations with, any person in connection with an unsolicited bona fide
written proposal for a Competing Transaction from such person if (a) the DTG
Board, after consultation with and based upon the written advice of independent
legal counsel, determines in good faith that such action is necessary for the
DTG Board to comply with its fiduciary duties to the stockholders of DTG under
applicable law, (b) DTG and such person enter into a confidentiality agreement
in reasonably customary form and terms, and (c) the DTG Board reasonably
believes in its good faith judgment after consultation with independent
financial advisors that such person has the financial ability to consummate a
Competing Transaction; and (2) fail to make or withdraw or modify its
recommendation of the Merger or make or disclose any position or take any other
action if the DTG Board, after consultation with and based on the written advice
of independent legal counsel, determines in good faith that such action is
necessary for the DTG Board to comply with its fiduciary duties to the
stockholders of DTG under applicable law. DTG has agreed (1) promptly to notify
McLeodUSA if any inquiries or proposals that constitute, or may reasonably be
expected to lead to, a Competing Transaction are received by DTG or any of its
subsidiaries, or any of its or their respective directors, officers, employees,
agents,

                                       43
<PAGE>
 
investment bankers, financial advisors, attorneys, accountants or other
representatives, (2) promptly to inform McLeodUSA as to the material terms of
such inquiry or proposal and, if in writing, promptly to deliver or cause to be
delivered to McLeodUSA a copy of such inquiry or proposal (unless the DTG Board,
after consultation with and based upon the written advice of independent legal
counsel, determines in good faith that such delivery would cause the DTG Board
to breach its fiduciary duties to the stockholders of DTG), and (3) to keep
McLeodUSA informed, on a current basis, of the nature of any such inquiries and
the status and terms of any such proposals. For purposes of the Merger
Agreement, "Competing Transaction" means any of the following involving DTG or

Agreement): (1) any merger, consolidation, share exchange, business combination,
or other similar transaction; (2) any sale, lease, exchange, mortgage, pledge,

therewith; (4) any solicitation of proxies in opposition to approval by the
stockholders of DTG of the Merger Agreement or the Merger; (5) any person shall
have acquired beneficial ownership or the right to acquire beneficial ownership
of, or any "group" (as such term is defined under Section 13(d) of the Exchange
Act) shall have been formed after the date of the Merger Agreement which
beneficially owns or has the right to acquire beneficial ownership of, 15% or
more of the then outstanding shares of capital stock of DTG or any of its
subsidiaries; or (6) any agreement or public announcement by DTG or any other
person of a proposal, plan or intention to do any of the foregoing.

STANDSTILL; CERTAIN OTHER AGREEMENTS OF MCLEODUSA

     McLeodUSA has agreed that if the Merger Agreement is terminated for any
reason other than as a result of DTG's willful failure to perform any covenant
or agreement or willful breach of any representation or warranty contained in
the Merger Agreement, and subject to payment by DTG of any applicable
termination fees and expenses, then, for a period of three years from the date
of the Merger Agreement, McLeodUSA will not, directly or indirectly, except
pursuant to the Merger Agreement:  (1) acquire or agree, offer, seek or propose
to acquire, or cause to be acquired, ownership of 15% or more of DTG's assets or
businesses or 15% or more of the voting securities of DTG, or any other rights
or options to acquire such ownership (including from a third party); (2) seek or
propose to influence or control DTG's management or policies, except that
McLeodUSA may vote any voting securities of DTG owned by it; or (3) enter into
any discussions, negotiations, arrangements or understandings with any third
party with respect to any of the foregoing.

     McLeodUSA has agreed to make a capital contribution to the Surviving
Corporation promptly following the closing of the Merger (the "Closing") in the
amount of $20 million.  McLeodUSA has also agreed to use its reasonable best
efforts to insure that any shares of McLeodUSA Common Stock issued upon exercise
of the McLeodUSA stock options replacing the DTG Stock Options in the Merger
will be registered under the Securities Act pursuant to a registration statement
on Form S-8 and will be approved for listing (subject to official notice of
issuance) by The Nasdaq Stock Market.  McLeodUSA has further indicated its
present intention regarding certain post-Merger operations of the Surviving
Corporation.

INDEMNIFICATION

     McLeodUSA has agreed that for the period from the Effective Time until at
least six years after the Effective Time, (1) it will cause the Surviving
Corporation to maintain and to honor (including, without limitation, by
providing the Surviving Corporation with sufficient funding) DTG's current
directors' and officers' insurance and indemnification policy and related
arrangements, or an equivalent policy and related arrangements, for all present
and former directors and officers of DTG, covering claims made and insurable
events occurring prior to or within six years after the Effective Time (provided
that the Surviving Corporation will not be required to maintain such policy
except to

                                       44
<PAGE>
 
the extent that the aggregate annual cost of maintaining such policy is not in
excess of 200% of the current annual cost, in which case the Surviving
Corporation shall maintain such policies up to an annual cost of 200% of the
current annual cost); and (2) it will cause the Surviving Corporation to
maintain and to honor (including, without limitation, by providing the Surviving
Corporation with sufficient funding) indemnification provisions, including,
without limitation, provisions for expense advances, for present and former
officers and directors in the Surviving Corporation's certificate of
incorporation and bylaws and certain agreements to the fullest extent permitted
by the DGCL.  McLeodUSA has also agreed to, or to cause the Surviving
Corporation to, indemnify and hold harmless, from and after the Effective Time,

costs, expenses (including reasonable attorneys' fees), judgments, fines and

Time, whether before or after approval by the stockholders of DTG:

          (1)  by mutual written consent of DTG and McLeodUSA;

          (2)  by McLeodUSA, if there has been a breach by DTG of any of its

     Merger Agreement, or any such representation and warranty shall have become

     business days following receipt by DTG of written notice of such breach;

          (3)  by DTG, if there has been a breach by McLeodUSA or Merger Sub of

     the other, if the Merger shall not have been consummated as a direct result
     of DTG having failed by such date to receive all regulatory approvals or
     consents required to be obtained by DTG with respect to the Merger, and (b)
     this right to terminate the Merger Agreement will not be available to any
     party whose willful failure to fulfill any obligation under the Merger
     Agreement has been the cause of, or resulted in, the failure of the
     Effective Time to occur on or before such date; and

          (7)  by DTG, if in connection with a proposal for a Competing
     Transaction the DTG Board determines in good faith, after consultation with

     under applicable law.

three business days after such termination, pay to McLeodUSA $500,000; and (2)
(a) if a Competing Transaction is consummated prior to the first anniversary of
such termination, then simultaneously with the

anniversary of such termination, then on the first anniversary of such
termination it will, at its option, (i) pay to McLeodUSA $2,000,000, or (ii)

                  INFORMATION ABOUT MCLEODUSA AND MERGER SUB

GENERAL

McLeodUSA.  McLeodUSA provides integrated communications services to business
and residential customers in the Midwestern and Rocky Mountain regions of the
United States.  McLeodUSA's integrated communications services include local,
long distance, Internet access, data, voice mail and paging, all from a single
company on a single bill.  McLeodUSA believes it is the first communications
provider in most of its markets to offer "one-stop shopping" for
communications services tailored to customers' specific needs.

     McLeodUSA's approach makes it easier for both its business and its
residential customers to satisfy their telecommunications needs. It also allows
businesses to receive customized services, such as competitive long distance
pricing and enhanced calling features, that might not otherwise be directly
available on a cost-effective basis. As of September 30, 1998, McLeodUSA served
over 366,800 local lines in 267 cities and towns.

     In addition to McLeodUSA's core business of providing competitive local,
long distance and related communications services, it also derives revenue from:

     .    the sale of advertising space in telephone directories
     .    incumbent local exchange services in east central Illinois
     .    communications network maintenance services
     .    telephone equipment sales, service and installation
     .    video services
     .    special access, private line and data services
     .    telemarketing services
     .    other communications services, including cellular, operator, payphone
          and paging services

     In most of its markets, McLeodUSA competes with the incumbent local phone
company by leasing their lines and switches.  This allows customers to select
McLeodUSA's local service without changing their existing telephone numbers.  In
other markets, primarily in east central Illinois, McLeodUSA operates its own
lines and switches.  McLeodUSA provides long distance services by using its own
facilities and leasing capacity from long-haul and local providers.  McLeodUSA
is constructing fiber optic networks in Iowa, Illinois, Wisconsin, Indiana,
Missouri, Minnesota, South Dakota and North Dakota to carry additional
communications traffic on its own network.

     McLeodUSA wants to be the leading and most admired provider of integrated
communications services in its markets.  McLeodUSA is:

     .    aggressively capturing customer share and generating revenue using
          leased network capacity
     .    concurrently constructing its own network
     .    migrating customers to its network to provide enhanced services and
          reduce operating costs

     The principal elements of McLeodUSA's business strategy include:

     .    Provide integrated communications services. McLeodUSA believes it can
          rapidly penetrate its target markets and build customer loyalty by
          providing a "bundled" product offering. McLeodUSA intends to add
          personal communications services to its current array of integrated
          communications services over the next several years.

     .    Build customer share through branding. McLeodUSA believes it will
          create and strengthen brand awareness in its target markets by
          branding its communications services with the

                                       51
<PAGE>
 
          trade name McLeodUSA in combination with the distinctive black-and-
          yellow motif of its directories.

     .    Provide outstanding customer service. McLeodUSA customer service
          representatives are available 24 hours a day, seven days a week, to
          answer customer calls. McLeodUSA's customer-focused software and
          systems allow its representatives immediate access to its customer and
          network data, enabling a rapid and effective response to customer
          requests.

     .    Focus on small and mid-sized markets. McLeodUSA primarily targets
          small and mid-sized markets because it believes it can rapidly capture
          customer share by providing face to face sales and service support to
          its customers before intense competition develops.
 
     .    Expand its fiber optic network. McLeodUSA is building a state-of-the-
          art digital fiber optic network to deliver multiple services and
          reduce operating costs.

     .    Expand intra-city fiber network build. Within selected cities,
          McLeodUSA plans to extend its network directly to its customers'
          locations. This will allow McLeodUSA to provide expanded services and
          reduce the expense of leasing facilities from the local exchange
          carrier.
 
     .    Explore acquisitions and strategic alliances. McLeodUSA plans to
          pursue acquisitions, joint ventures and strategic alliances to expand
          or complement its business.

     .    Leverage proven management team. McLeodUSA's executive management team
          consists of veteran telecommunications managers who successfully
          implemented similar customer-focused telecommunications strategies in
          the past.
 
                                 _____________

     As of September 30, 1998, McLeodUSA estimated, based on its current
business plan and projections, its aggregate capital requirements through 2001
would be $1.1 billion. McLeodUSA's estimated capital requirements include the
projected cost of:

     .    building its fiber optic network, including intra-city fiber optic
          networks
     .    expanding operations in existing and new markets
     .    developing a PCS system
     .    funding general corporate purposes

     McLeodUSA expects to fund these capital requirements with:

     .    approximately $291.9 million in net proceeds from its senior note
          offering in October 1998
     .    approximately $402.4 million of cash and investments on hand at
          September 30, 1998
     .    a proposed $100.0 million revolving credit facility
     .    projected operating cash flows of McLeodUSA

     The actual amount and timing of McLeodUSA's future capital requirements is
subject to risks and uncertainties and may differ materially from the its
estimates.  See "Risk Factors Significant Capital Requirements."
 
                                 _____________

Merger Sub.  Merger Sub is a Delaware corporation and a wholly owned subsidiary

(1)  Reflects the preliminary allocation of the net purchase price of DTG to the
assets of DTG that are to be acquired including intangible assets,  and
records the issuance of 1,295,000 shares of McLeodUSA Common Stock valued at
$35.54 per share (the average closing price of McLeodUSA Common Stock on The
Nasdaq Stock Market for the eleven trading days beginning five days prior to the
date the Merger Agreement was announced, October 27, 1998, and ending five days
after such announcement).  For purposes of allocating the net purchase price
among the various assets to be acquired, McLeodUSA has tentatively considered
the carrying value of the acquired assets to approximate their fair value, with
all of the excess of the net purchase price being attributed to intangible
assets.  McLeodUSA intends to more fully evaluate the acquired assets following
consummation of the Merger and, as a result, the allocation of the net purchase
price among the acquired tangible and intangible assets may change.  The
adjustments include the elimination of the DTG equity components, including
common stock, treasury stock, other capital, retained deficit and unearned
Employee Stock Ownership Plan shares of DTG Common Stock.

                            INFORMATION ABOUT DTG 
GENERAL


     DTG is a Delaware corporation that was organized in 1997. Its predecessor
was Dakota Cooperative Telecommunications, Inc., a stock-based South Dakota
cooperative association that was formed on April 3, 1952 (as previously defined,
the "Cooperative"). In July 1997, the Cooperative was converted into a South
Dakota business corporation and then merged with and into DTG (as previously
defined, the "Conversion-Merger"). DTG was the surviving corporation in the
Conversion-Merger. The mailing address of the DTG's principal executive office
is Post Office Box 66, 29705 453rd Avenue, Irene, South Dakota 57037-0066, and
the phone number is (605) 263-3301.


BUSINESS

     DTG is a diversified communications services company specializing in the
design, construction and operation of broadband telecommunications systems for
communities in South Dakota and the surrounding states. DTG currently operates
13 telephone exchanges in Southeastern South Dakota, four of which were built in
1997, and 26 cable television systems in South Dakota, Iowa and Minnesota
incorporating over 2,240 miles of copper plant, 300 miles of coaxial cable and
approximately 9,100 fiber miles of fiber optic lines. DTG's main growth strategy
is to continue to expand and build new systems in South Dakota, Minnesota, Iowa
and Nebraska.

     DTG provides a full range of bundled telecommunications products and
services to its customers including switched local dial tone and enhanced
services, network access services, long distance telephone services, operator
assisted calling services, telecommunications equipment sale and leasing
services, cable television services, Internet access and related services and
computer networking services. DTG's customer base includes approximately 7,350
local service access lines, 5,930 cable television subscribers, 7,200 Internet
users, and over 2,000 active computer networking business customers located
primarily in South Dakota, Northwestern Iowa and Southwestern Minnesota. DTG and
its predecessors have been engaged in the telecommunications business since
1903.

     DTG was originally incorporated as a stock cooperative in South Dakota
on April 3, 1952, through the consolidation of several small independent
telephone companies in Southeastern South Dakota. From the date of formation
through 1979, DTG operated principally as a telephone company. Today, DTG
continues these operations and has expanded into cable television and other
related telecommunications services. In 1979, DTG expanded into community
antenna television cable ("CATV") by building cable systems in its local
markets. In the mid-1980s, DTG expanded into the cellular market through
partnerships with cellular companies serving DTG's market area. DTG sold its
rural cellular operations in 1994 and its Sioux Falls, South Dakota cellular
operations in 1995, in an effort to focus on new wireless technologies. DTG
expanded its cable operations in 1995 and 1996, and further expanded with the
acquisitions in 1996 of TCIC Communications, Inc. ("TCIC") (long distance and
operator services), I-way Inc. ("I-way") (Internet services), and in 1997 of
Futuristic, Inc. dba DataNet ("DataNet") (computer network integration
services). All three companies continue to operate as wholly-owned subsidiaries
of DTG under the names DTG Communications, Inc., DTG Internet, Inc. and DTG
DataNet, Inc., respectively. In July 1998 DTG acquired by merger Vantek
Communications, Inc. and Van/Alert, Inc., two South Dakota corporations
(collectively, "Vantek"). Vantek is a leading mobile radio operator and operates
one of the largest paging businesses in South Dakota. Furthermore, in November
1998, DTG completed its acquisition of Hurley Communications, Inc. See
"Information About DTG--Recent Developments." As a result of this expansion,
today DTG is a diversified telecommunications services company, 

                                       60

offering product and service bundles which currently cannot be matched by any
single competitor in its existing and selected target markets. DTG intends to
continue to explore expansion through strategic acquisitions and business
alliances in an effort to facilitate the growth of DTG.

     TELECOMMUNICATIONS INDUSTRY OVERVIEW.  From the formation of the telephone
industry in the late 1800s until the breakup of AT&T in 1984, the
telecommunications industry was largely dominated by AT&T through its ownership
and operation of the Bell operating companies. Rural areas which provided little
market share for AT&T were left to be served by small independent telephone
companies like DTG and its predecessors. In 1984, the structure of the industry
was significantly changed by the AT&T divestiture decree, which required the
divestiture by AT&T of its 22 Bell operating companies and divided the country
into 201 local access and transport areas ("LATAs") (the "AT&T Divestiture
Decree"). The Bell operating companies were combined into seven RBOCs and were
permitted to provide local telephone service, local access service to long
distance carriers and long distance ("intra-LATA") service within the LATAs.
However, the Bell operating companies were prohibited from providing inter-LATA
long distance service, or service between LATAs.

     The AT&T Divestiture Decree had a profound effect on the long distance
portion of the telecommunications industry in the United States. To encourage
competition in the long distance market, the AT&T Divestiture Decree and certain
FCC regulations require most local exchange companies ("LECs") to provide
carriers with access to local exchange service that is "equal in type, quality
and price" to that provided by AT&T and to allow customers to select their
preferred long distance service provider. As a result, a large number of
companies specializing in long distance services entered the market.

     For each long distance call, the originating and terminating local exchange
carriers ("LECs") charge an access fee to the long distance carrier. The long
distance carrier charges its customers a fee for its transmission of the call, a
portion of which covers the cost of the access fees charged by the LECs. Access
charges represent a significant portion of DTG's gross revenues from its local
exchange operations as well as a significant portion of DTG's cost of providing
long distance services. Generally, the FCC and the states regulate such access
charges. The FCC has undertaken a comprehensive review of its regulation of LEC
access charges to better account for increasing levels of local competition.

     In February 1996, President Clinton signed the Telecommunications Act. The
Telecommunications Act significantly changed the telecommunications industry by
(among other things) removing certain of the restrictions concerning the
provision of long distance service by the RBOCs. The RBOCs, however, are
required to obtain specific FCC approval and satisfy other conditions, including
a checklist of interconnection and other requirements applicable to LECs, prior
to providing long distance service in the regions in which the LECs provide
local exchange service. In addition, the Telecommunications Act opened local
service telecommunications markets to competition by preempting state and local
laws to the extent that such laws prevent competition in the provision of any
telecommunications service, and by imposing a variety of new duties on LECs to
promote competition in local exchange services. Among other requirements, all
LECs, including DTG, are required, on a non-discriminatory basis, to permit
resale of their telecommunications services without unreasonable restrictions or
conditions. The law and its accompanying regulations will enable DTG, upon
receipt of all necessary regulatory approvals, to resell local
telecommunications services in exchanges outside of DTG's traditional service
territories in addition to its existing long distance services. The basis upon
which such local services will be available to carriers such as DTG for resale
are to be determined in proceedings of various state public utilities
commissions. DTG believes that the opening of the local telecommunications
services market to resellers provides DTG with significant growth opportunities
while posing a much smaller threat in its small rural local exchanges.

     BUSINESS STRATEGY.  DTG's business strategy is to attempt to achieve
continued growth through the construction and operation of new broadband
telecommunications systems and by developing and marketing a broad array of
competitively priced telecommunications services over these systems. DTG's
primary objectives in pursuing this strategy are to:

     (i)   develop new and enhanced products and services through upgrading
           DTG's existing network and expanding this network, where feasible,
           into new markets. DTG substantially rebuilt its existing network in
           1997 and plans to continue expanding this infrastructure;

     (ii)  expand DTG's sales and marketing activities by increasing its
           advertising and promotional activities and enlarging its sales force
           to include direct and independent sales representatives. DTG intends
           to supplement its sales force by rebuilding its customer support
           functions, enhancing its strong field service operations and
           improving its direct billing capabilities; and

     (iii) expand its revenue base through selected acquisitions of companies
           and facilities in the telecommunications and cable television
           industries and other related industries.

     There can be no assurance that DTG will be successful in implementing its
business strategy or attaining the profitable growth that is desired.

     LOCAL TELECOMMUNICATIONS SERVICES.  DTG's local telecommunications services
are provided directly by DTG.  As of October 31, 1998, DTG provided services to
approximately 7,500 access lines located in Southeastern South Dakota.  DTG's
service area is generally rural, covering approximately 1,100 square miles, with
an average of 5.4 access lines per square mile.  DTG is classified as a "rural
company" under the Telecommunications Act and receives Universal Service Fund
monies, although such funds constituted less than one percent of DTG's gross
revenues in 1997.

     DTG's local telecommunications services include: (i) local dial tone; (ii)
local private line and public telephone services (including dial tone service
for pay telephones owned by DTG and other pay phone providers); (iii) dedicated
and switched data transmission services; (iv) the sale, installation and
maintenance of customer premise equipment; and (v) related services such as
directory listing services.  In connection with DTG's continuing strategy to
provide a greater selection of value-added products, DTG has also introduced
advanced services such as Caller ID, distinctive ringing, call waiting, call
forwarding and three-way calling.  DTG also introduced its new Distance Learning
program, which links 12 local schools with the University of South Dakota's
School of Education to allow these local schools to share interactive televised
classroom sessions.

     In addition to providing local telephone service, DTG also provides network
access services to national and regional interexchange carriers ("IXCs").
Network access service refers to the link provided by LECs between a customer's
premises and the transmission facilities of other telecommunications carriers,
generally inter-LATA long distance carriers.  Examples of exchange access
services include switched access and special access services.  Network access
revenues are billed directly to long distance carriers based on the number of
conversation minutes generated by their customers located in DTG's exchanges.
The interstate portion of these revenues is based on switched, common-line and
special access tariffs approved by the FCC.  The tariffs imposed by the FCC
include end-user access charges to residential and business customers.  State
access is based on similar rate structures that are subject to approval by the
South Dakota Public Utilities Commission.  Unlike many LECs, DTG does not
provide billing or collection services for interexchange long distance carriers
operating in DTG's local exchanges.

                                       62
<PAGE>
 
     Local service, including network access services, has historically been
DTG's core business. In 1997, revenues from local services were approximately
$5.4 million, representing approximately 39% of DTG's aggregate revenues.  As a
result of DTG's diversification through the acquisitions described above, this
percentage has changed.  For the nine months ended September 30, 1998, local
exchange service revenues accounted for only 22% of DTG's total revenues.
Although network bypass and alternative local access telephone service providers
are potential competitive threats to DTG, no significant competition has
occurred to date in DTG's incumbent local exchange communities.  Competition is
very active in the new communities DTG enters as part of its CLEC expansion
strategy.

     LONG DISTANCE TELECOMMUNICATION SERVICES.  DTG provides a wide range of
long distance telecommunications services to approximately 3,700 residential and
commercial customers located primarily in South Dakota.  These services include:
(i) basic long distance calling service; (ii) voice and data services; (iii)
dedicated private line services; (iv) collect calling, operator assistance and
calling card services, including prepaid calling cards; (v) toll free or 800
services; and (vi) switched and dedicated Internet access services.  DTG offers
these services individually and in combinations. Through combined offerings, DTG
is able to provide customers with added benefits such as single billing, unified
services for multi-location companies and customized calling plans.

     DTG operates its own switches, develops and implements its own products,
monitors and deploys its transmission facilities and prepares and designs its
own billing and reporting systems.  All of DTG's customers are identified by
their telephone number, dedicated trunk or validated access code, and have a
rating which is used to determine the price per minute that they pay on their
outbound or inbound long distance calls. Rates typically vary by the type of
service, the volume of usage, the distance of the calls, the time of day that
calls are made, the region that originates the call and whether the product is
being provided on a promotional basis. In 1997, long distance revenues were
approximately $3.5 million, representing 25% of DTG's gross revenues. For the
nine months ended September 30, 1998, this percentage had decreased to 11% due
primarily to the acquisition of DataNet. DTG anticipates that its long distance
revenues will continue to grow, due to the construction of new
telecommunications systems and DTG's sales efforts.

     DTG provides long distance services in various ways.  For customers located
in DTG's local South Dakota exchanges, long distance services are provided
primarily by DTG as part of its local service.  For customers located outside of
DTG's local exchanges or using operator assisted services, all long distance
services are provided by DTG Communications, Inc., DTG's wholly owned
subsidiary. Currently DTG Communications, Inc. is authorized to sell long
distance services in North Dakota, South Dakota, Iowa, Nebraska, Minnesota,
Montana and several other states. However, most of DTG's long distance revenues
are derived from South Dakota. Internet long distance access services are
provided by DTG Internet, Inc.

     WIRELESS SERVICES. On July 1, 1998, DTG completed the merger of Vantek
Communications, Inc., a small mobile radio systems operator, and Van/Alert,
Inc., a paging operation under common ownership with Vantek, into Dakota
Wireless Systems, Inc., a wholly owned subsidiary of DTG.  As of October 31,
1998, the company had 256 small mobile radio customers and approximately 1,200
paging customers located in southeastern South Dakota.

     In addition, DTG has deployed a wireless local loop operation in certain of
its small telephone exchanges in Southeastern South Dakota.  Wireless local loop
uses specialized radio frequency transmissions to replace the wireline
connections to the company's subscribers.  The company plans to continue to test
and deploy this technology as it expands its CLEC operations.

     INTERNET SERVICES.  DTG is the largest provider of Internet services in
South Dakota. DTG provides a wide range of Internet services including Internet
access options (both dial-up and dedicated), Web page development and hosting
services, Internet applications development and 

                                       63
<PAGE>
 
training and consulting services to businesses, professionals and other on-line
services providers. As of September 30, 1998, DTG hosted approximately 170 Web
sites with additional sites under development. DTG estimates that its access
services are used by approximately 6,800 users. Total Internet revenues in 1997
were approximately $1 million, representing approximately 7% of DTG's total
gross revenues. This percentage has decreased to approximately 5% of total
revenues for the nine months ended September 30, 1998 due to the acquisition of
DataNet in December 1997.

     In December 1994, I-way started its Internet operations, which DTG
purchased in December 1996.  I-way, now renamed DTG Internet, Inc., operates as
a wholly owned subsidiary of DTG.  DTG anticipates that in the future it may
attempt to consummate additional acquisitions to expand its Internet service
base.

     The Internet is a global collection of computer networks cooperating to
enable commercial organizations, educational institutions, government agencies
and individuals to communicate electronically, access and share information and
conduct business.  The Internet originated with the ARPAnet, a restricted
network started in 1969 by the United States Department of Defense Advanced
Research Projects Agency to provide efficient and reliable long distance data
communications among the disparate computer systems used by government-funded
researchers and organizations. Unlike other public and private
telecommunications networks that are managed by businesses, government agencies
and other entities, the Internet is a cooperative interconnection of many such
public and private networks. The networks that comprise the Internet are
connected in a variety of ways, including public switched telephone network and
high-speed, dedicated leased lines. Communications on the Internet are enabled
by transmission control protocol/Internet protocol ("TCP/IP"), an Internet-
working standard that enables communications across the Internet regardless of
the hardware and the software used.

     Recent technological advances, including increased microprocessor speeds
and the development of easy-to-use graphic interfaces, combined with cultural
and business changes, have led to the Internet being integrated into the
activities of a multitude of individuals and the operations and strategies of
numerous business organizations.  For example, a growing number of employees
within organizations have access to corporate networks, thereby increasing the
amount of electronic communication both within and between organizations.  In
addition, the rapid growth of the installed base of home personal computers
equipped with communication devices such as modems has created the ability to
communicate electronically from home.  These technological and business trends
have led to an increase in the number of on-line services and Internet access
providers.

     More recently, the development of World Wide Web technology and associated
easy-to-use software has made the Internet easier to navigate and more
accessible to a larger number of users and for a broader range of applications.
While there has been significant media interest in the use of the Internet by
consumers, business and professional organizations currently represent a more
significant percentage of Internet use. These organizations increasingly are
recognizing that the Internet can enhance communications, both among their
geographically distributed locations and employees, and with their business
partners and customers. In addition, businesses are realizing that the Internet
can enable many applications which were previously unavailable or cost-
prohibitive. For example, small and medium-sized businesses can establish and
maintain a global presence and market and distribute their products and services
electronically.

     Despite the growing interest in the many commercial uses of the Internet,
DTG believes that many businesses, especially small businesses, have been
deterred from purchasing Internet access services for a number of reasons,
including: (i) inconsistent quality of service; (ii) lack of availability of
cost-effective high-speed options; (iii) limited number of local access points
for corporate users and customers; (iv) inability to integrate business
applications on the Internet; (v) need to deal with multiple and frequently
incompatible vendors; (vi) inadequate protection of the confidentiality of

                                       64
<PAGE>
 
stored data and information moving across the Internet; and (vii) lack of tools
to simplify Internet access and use.

     To address the needs of small businesses in South Dakota and surrounding
states, DTG offers a comprehensive range of Internet access options,
applications, training and consulting services tailored to meet the needs of
small and medium-sized businesses and their customers. The products and services
provided by DTG include dial-up and dedicated access, Web page development, Web
page hosting, client software and security products and training. This array of
products and services enables Internet users to purchase access, applications
and services, including integration services, through a single source. DTG's
products and services are supported by a technical staff that it believes is
highly experienced in Internet operations and services, especially as they
relate to small businesses. DTG's objective is to continue to develop and market
value-added Internet services in the smaller markets in South Dakota and the
surrounding states. Rates for DTG's Internet services vary depending on the type
and range of service options.

     CABLE TELEVISION SERVICES.  Through its subsidiaries, DTG owns and operates
26 cable television systems located in Southeastern South Dakota, Northwestern
Iowa and Southwestern Minnesota ranging in capacity from 300 to 750 MHZ. As of
October 31, 1998, these systems provided service to approximately 5,930
subscribers. No single community accounts for more than 12% of DTG's total basic
CATV subscribers. DTG believes that this geographic diversity reduces its
exposure to adverse economic, competitive and regulatory factors in any
particular community.

     Total cable revenues in 1997 were approximately $1.5 million, representing
approximately 11% of DTG's total gross revenues.  For the nine months ended
September 30, 1998, this percentage had decreased to 5% due primarily to the
acquisition of DataNet in December 1997.

     DTG has been engaged in the cable television business since 1979.  In 1996,
as part of its expansion strategy, DTG acquired the assets of 19 of its total
cable television systems, accounting for approximately 3,600 of the 5,500
current subscribers. DTG anticipates that in the future it may attempt to
consummate additional acquisitions to expand its customer base and service
markets.

     Cable television systems receive video, audio and data signals transmitted
by nearby television and radio broadcast stations, terrestrial microwave relay
services and communications satellites.  Such signals are then amplified and
distributed by coaxial cable and optical fiber to the premises of customers who
pay a monthly fee for the service. DTG does not hold any dedicated spectrum
licenses issued by the FCC related to its cable television operations, although
DTG believes that it holds all other necessary licenses to operate its systems.
The number of channels provided by DTG varies by service area.  The sources of
DTG's cable television programming consist of the signals received from national
television networks, local and other independent television stations that
operate in or near DTG's service areas, satellite-delivered non-broadcast
channels and public service channels and announcements.

     DTG provides programming to its subscribers pursuant to contracts with
programming suppliers. DTG generally pays a flat monthly fee per subscriber for
programming on its basic and premium services. A number of programming suppliers
provide volume discount pricing structures and/or offer marketing support to DTG
through DTG's participation in a purchasing pool with other small cable system
operators. DTG's programming contracts generally are for fixed periods of time
ranging from 3 to 10 years and are subject to negotiated renewal. The costs to
DTG to provide cable programming have increased in recent years and are expected
to continue to increase due to additional programming being provided to basic
subscribers, increased costs to produce or purchase cable programming,
inflationary increases and other factors. Effective in May 1994, the FCC's rate
regulations under the Cable Television Consumer Protection and Competition Act
of 1992 (the "1992 Cable Act") permitted operators to pass through to customers
increases in programming costs in excess of the inflation rate. Management
believes that DTG will continue to have access to 

                                       65
<PAGE>
 
programming services at reasonable price levels, although there can be no
assurance that DTG can in the future maintain its access at reasonable price
levels.

     Monthly fees for cable services vary depending on the nature and type of
service. DTG offers a basic cable service package (primarily comprised of local
broadcast signals, popular national satellite channels and public, educational
and governmental access channels) and premium movie channels. The monthly fee
for basic service generally ranges from $17.95 to $24.95 depending on the number
of channels offered, and the monthly service fee for premium channels is $7.95
per channel. Also, DTG generally assesses a nonrecurring installation charge of
up to $35.00. Customers are free to discontinue service at any time without
penalty. DTG currently does not offer Pay-TV or "pay-per-view" services but
anticipates doing so in the future as it upgrades the capacity of its systems.

     DTG's cable television business is dependent to a large extent on its
ability to obtain and renew its franchise agreements with local government
authorities on acceptable terms. DTG believes that it has maintained good
relations with its local franchise authorities and has never had a franchise
revoked. Most of DTG's present franchises had initial terms of approximately 10
to 15 years. As of September 30, 1998, all of DTG's franchises have been renewed
or extended, generally at or prior to their stated expirations and on terms
which are acceptable to DTG. In this regard, during 1996, DTG completed
negotiations with 19 communities resulting in franchise renewals. Federal law,
including the Cable Communications Policy Act of 1984 (the "1984 Cable Act") and
the 1992 Cable Act, limits the power of the franchising authorities to impose
certain conditions upon cable television operators as a condition of the
granting or renewal of a franchise. DTG has 26 franchises, three of which are up
for franchise renewal within the next three years. No one cable television
franchise accounts for more than 10% of DTG's total cable television revenue.

     Franchise agreements generally contain varying provisions relating to
construction and operation of cable television systems, including: (i) time
limitations on the commencement and/or completion of construction; (ii) quality
of service, including (in certain circumstances) requirements as to the number
of channels and broad categories of programming offered to subscribers; (iii)
rate regulation; (iv) provision of services to certain institutions; (v)
provision of channels for public access and commercial leased-use; and (vi)
maintenance of insurance and/or indemnity bonds.  DTG's franchises also
typically provide for periodic payments of fees, generally ranging from zero to
three percent of revenues, to the governmental authority which grants the
franchise.  Franchises usually require the consent of the franchising authority
prior to a transfer of the franchise or a transfer or change in ownership or
operating control of the franchisee.

     Subject to applicable law, a franchise may be terminated prior to its
expiration date if the cable television operator fails to comply with the
material terms and conditions of the franchise.  Under the 1984 Cable Act, if a
franchise is lawfully terminated, and if the franchising authority acquires
ownership of the cable television system or effects a transfer of ownership to a
third party, such acquisition or transfer must be at an equitable price or, in
the case of a franchise existing on the effective date of the 1984 Cable Act, at
a price determined in accordance with the terms of the franchise, if any.

     In connection with a renewal of a franchise, the franchising authority may
require the cable operator to comply with different and more stringent
conditions than those originally imposed, subject to the provisions of the 1984
Cable Act and other applicable federal, state and local law.  The 1984 Cable
Act, as supplemented by the renewal provisions of the 1992 Cable Act,
establishes an orderly process for franchise renewal which protects cable
operators against unfair denial of renewal when the operator's past performance
and proposal for future performance meet the standards established by the 1984
Cable Act.  DTG believes that its cable television systems generally have been
operated in a manner which satisfies such standards and allows for the renewal
of such franchises; however, there can be no assurance that the franchises for
such systems will be successfully renewed as they expire.

     COMPUTER NETWORKING SERVICES. Through its DataNet subsidiary, DTG is a
leading provider of services and products designed to build and manage personal
computer network infrastructures for businesses throughout its service
territories. DTG provides customized, integrated solutions for its customers'
distributed computing networks by combining a comprehensive offering of value-
added services with its expertise in sourcing and distributing PCs, network
products, computer peripherals and software from a variety of vendors. DTG
endeavors to provide a one-stop source for integrating the design and
consulting, acquisition and deployment, operation and support, and enhancement
and migration of computer network operations. Typical services provided by DTG
include the review of customer system requirements; the selection, design and
planning of system components; the procurement, configuration, distribution,
installation, cabling and connectivity of complete computer networks; and
operating and network support services such as equipment adds, moves, and
changes, repair and maintenance, help desk operations, and network monitoring.
DTG's computer networking customer base extends to approximately 6,000 business
customers throughout South Dakota and the surrounding states, with approximately
2,000 accounts active at any one time. In 1997, total revenues from computer
networking services were approximately $1.8 million, representing approximately
13% of DTG's total gross revenues. However, DTG operated its DataNet subsidiary
for only one month in 1997. For the nine months ended September 30, 1998,
computer networking services accounted for approximately 54% of DTG's total
revenues.

     MAIN NETWORK OPERATIONS.  DTG provides its local services and related long
distance services primarily over its own network.  DTG operates an advanced
digital telecommunications network consisting of one Lucent 5ESS switch with
nine subtending switches for its local services network, one Summa Logic digital
switch for operator services and advanced long distance services, leased
transmission lines to complete calls for its domestic and international long
distance services and sophisticated network management systems designed to
optimize traffic routing. DTG's network encompasses approximately 2,240 miles of
copper trunk lines and customer connections and about 290 route miles of fiber
optic cabling.

     DTG seeks to actively manage and improve its network.  DTG spent
approximately $10 million in 1997 to complete the deployment of Synchronous
Optical Network ("SONET") fiber rings within its network and centralize and
upgrade its switching equipment through the construction of a new switching
center and the installation of a Lucent 5ESS switching platform with advanced
digital switching technologies.  DTG currently plans to continue to expand its
SONET network backbone in 1998 as it builds networks in communities as part of
its CLEC expansion plan.

     SONET technology substantially increases the speed at which data is carried
on DTG's network, thereby allowing DTG to provide high-speed multimedia
applications and information services throughout its network. In addition, SONET
permits DTG to install customer circuits more quickly and improves monitoring of
the network by anticipating certain problems before they occur. Further, when
deployed in a ring design, SONET allows DTG to provide its customers with
millisecond restoration of traffic in the event of a network outage.

     INTERNET NETWORK OPERATIONS.  DTG's Internet network is based on leased
circuits and frame-relay based network access to the Internet National Access
Points ("NAPs") in Denver, Colorado, and Willow Springs, Illinois (a southern
suburb of Chicago). This gives DTG full physical redundancy to the main MCI
WorldCom Internet backbone. This network is controlled by a Bay Networks router
located in DTG's Internet network operations center in Sioux Falls, South
Dakota. Customers are able to access this network through dedicated lines, by
dialing into existing frame relay circuits or by placing a local or long
distance call (dial-up) through modems to the Sioux Falls switching center. Once
connected, the customer's traffic is routed through the operation center modem
banks to the Bay Networks router and into the Internet via DTG's NAP
connections.

                                       67
<PAGE>
 
     DTG continues to upgrade its network infrastructure in response to the
increased number of customers purchasing Internet access and Web page hosting
services.  DTG also currently plans to increase its NAP access speeds to handle
larger levels of customer traffic at higher data transfer speeds.

     CABLE NETWORK OPERATIONS.  DTG uses a combination of coaxial cable and
optical fiber for transmission of television signals to subscribers.  Optical
fiber is a technologically advanced transmission medium capable of carrying
cable television signals via light waves generated by a laser.  DTG currently
uses fiber optic technology to serve 10 communities with a single CATV head-end
facility.  DTG anticipates that it will convert several additional systems over
the next several years.  It is anticipated that the systems, which facilitate
digital transmission of voice, video and data signals as discussed below, will
have optical fiber to neighborhood nodes tied to DTG's telecommunications
network with coaxial cable distribution downstream to subscribers' homes from
that point.

     The balance of DTG's cable systems currently operate on a stand-alone basis
with each community system supported by its own signal processing center, known
as a cable "head-end." A typical Company system consists of signal receiving,
encoding and decoding apparatus, distribution systems and subscriber house-drop
equipment. The signal receiving apparatus typically includes a tower, antenna,
ancillary electronic equipment and earth stations for reception of satellite
signals. Head-ends, consisting of associated electronic equipment necessary for
the reception, amplification and modulation of signals, are located near the
receiving devices. DTG's distribution systems consist of coaxial cables and
related electronic equipment. Subscriber equipment consists of taps, house
drops, converters and analog addressable converters.

     In 1997, DTG rebuilt four of its cable systems using advanced digital fiber
optic/coax cabling techniques that allow it to offer both cable television and
additional telecommunications services, such as local and long distance calling
and high speed data transmission and Internet access services, over the same
network. These systems are interconnected to DTG SONET fiber optic network and
switched from its new centralized switching facility. DTG also currently plans
to install digital advertising insertion equipment in its central switching
center. This equipment would allow DTG to significantly enhance the flexibility
and reliability of its advertising sales. These enhancements enable DTG to offer
increased programming channels with a higher quality signal at a lower per
channel cost.

COMPETITION

     The telecommunications industry is highly competitive and affected by rapid
regulatory and technological change. Regulatory trends have had, and may have in
the future, significant effects on competition in DTG's industry. New technology
is continuing to expand the types of available communications services and
equipment and the number of competitors offering such services. DTG faces actual
and potential competition in all of its businesses. Most of DTG's competitors
are large companies which have considerably greater financial, technological,
marketing and other resources than DTG.

     DTG believes that the factors critical to a customer's choice of a
telecommunications services provider are cost, ease of use, speed of
installation, quality, reputation and, in some cases, geography and network
size.  DTG's objective is to be one of the most responsive service providers in
the telecommunications industry, particularly when providing customized
communications services.  DTG recognizes that it must grow to be able to compete
effectively in the changing telecommunications industry and to avail itself of
greater economies of scale and increased scope in its transport and local access
requirements and in its back office operations.  It is for this reason that DTG
expanded its business through the purchase of additional cable television
systems and the 

                                       68
<PAGE>
 
acquisition of companies in the long distance and Internet long distance
industries (i.e., TCIC and I-way) and through the DataNet acquisition. These
additions have expanded DTG's product line and service abilities and should
enhance its ability to compete more effectively in its changing business and
regulatory environment.

     LOCAL SERVICE COMPETITION.  Historically, DTG's local telephone operations
have not experienced significant competition.  DTG's local telephone operations
may experience increased competition from various sources, including resellers
of DTG's local exchange services, large end-users installing their own networks,
IXCs, satellite transmission services, cellular communications providers, cable
television companies, radio-based personal communications service companies,
competitive access providers and other systems capable of completely or
partially bypassing local telephone facilities.  In 1996, the South Dakota
Public Utilities Commission approved numerous applications to provide and resell
local exchange services, including applications made by DTG to compete in other
local exchanges throughout South Dakota.  Numerous such applications are pending
and DTG anticipates that other companies will make additional filings.  DTG
cannot predict the specific effects of competition on its local telephone
business, but intends to attempt to take advantage of the various opportunities
that competition should provide, including expanding into additional market
areas, if it is able to do so.  DTG is currently attempting to address potential
competition by focusing on improved customer satisfaction, reducing costs,
increasing efficiency, improving its digital network, restructuring rates and
examining new product offerings and new markets for entry.

     LONG DISTANCE AND OPERATOR SERVICE COMPETITION.  The long distance and
operator services industries are highly competitive and dominated on a volume
basis by the nation's three largest long distance providers:  AT&T,  Sprint, and
MCI Worldcom.  These companies, and many of the other long distance providers,
surpass DTG in size and available financial, technological, marketing and other
resources.  All of these companies potentially can compete with DTG in the long
distance and operator services markets in which DTG currently operates.

     In addition, the Telecommunications Act permits RBOCs to provide long
distance telecommunications services internationally and domestically in
territories outside of the RBOCs' respective local service regions.  RBOCs also
may provide long distance telecommunications services that are incidental to
certain other services, such as wireless and video services, in their local
regions.  The authority to provide long distance telecommunications services
originating outside of the RBOCs' respective regions does not currently include
calls that terminate in-region, such as private line services, 800 services or
any equivalent service, and allows the contacted party to choose the inter-LATA
carrier.  RBOCs are prohibited from providing a full range of long distance
telecommunication services in their local regions until certain important
conditions are met.  RBOCs own extensive facilities in their regions and have
long-standing customer relationships and substantial capital resources, which
permit them to expend funds on technological and marketing improvements.  DTG
believes that in the future RBOCs will become substantial competitors for long
distance telecommunications services, especially in their local regions.

     INTERNET COMPETITION.  The market for data communications services,
including Internet access, computer networking services and on-line services, is
extremely competitive.  There are no substantial barriers to entry, and DTG
expects that competition will intensify in the future.  DTG believes that its
ability to compete successfully will depend on a number of factors, including:
(i) market presence; (ii) the ability to execute a rapid expansion strategy;
(iii) the capacity, reliability and security of its network infrastructure; (iv)
ease of access to and navigation of the Internet; (v) the pricing policies of
its competitors and suppliers; (vi) the timing of the introduction of new
products and services by DTG and its competitors; (vii) DTG's ability to support
industry standards; and (viii) industry and general economic trends.  DTG
believes that its success in the data communications services market will depend
heavily upon its ability to provide high-quality Internet connectivity and
value-added Internet services at competitive prices.

                                       69
<PAGE>
 
     DTG's current and potential competitors headquartered in the United States
may be divided into the following three groups:  (i) telecommunications
companies, such as AT&T, MCI, Sprint, RBOCs and @Home (a joint venture between
Tele-Communications, Inc. and a venture capital firm), and various other cable
companies; (ii) other Internet access providers, such as BBN Corporation
("BBN"), NETCOM On-Line Communication Services, Inc. ("NETCOM"), PSINet, Inc.
("PSI") and other national and regional providers; and (iii) on-line services
providers, such as America Online, Inc. ("America Online"), CompuServe
Corporation ("CompuServe"), Intuit Inc., Microsoft Corporation and Prodigy
Services Company.  Most of these competitors have greater market presence,
engineering and marketing capabilities, and financial, technological, personnel
and other resources than those available to DTG.  As a result, they may be able
to develop and expand their communications and network infrastructures more
quickly, adapt more swiftly to new or emerging technologies and changes in
customer requirements, take advantage of acquisition and other opportunities
more readily and devote greater resources to the marketing and sale of their
services.

     DTG expects that most of the major on-line services providers and
telecommunications companies will expand their current services to compete fully
in the Internet access market.  DTG believes that new competitors, including
large computer hardware, software, media and other technology and
telecommunications companies, will enter the Internet access market, resulting
in even greater competition to DTG.  Certain companies, including America
Online, AT&T, BBN and PSI, have obtained or expanded their Internet access
products and services as a result of acquisitions and strategic investments.
Such acquisitions or investments may permit these companies to devote greater
resources to the development and marketing of new competitive products and
services and the marketing of existing competitive products and services.  DTG
expects acquisitions and strategic investments by its competitors to increase,
thus creating significant new competitors.  In addition, the ability of some of
DTG's competitors to bundle other services and products with Internet access
services, such as the Internet service offerings recently offered by AT&T and
MCI, could place DTG at a further competitive disadvantage.

     As a result of increased competition in the Internet access and on-line
services industry, DTG expects that it will continue to encounter significant
pricing pressure, which in turn could result in significant reductions in the
average selling price of its Internet services.  DTG previously has reduced
prices on certain of its Internet access options and may consider doing so in
the future.  There can be no assurance that DTG will be able to offset the
effects of any such price reductions with an increase in the number of its
customers, higher revenue from enhanced services, cost reductions or otherwise.
In addition, DTG believes that the data communications business, and in
particular the Internet access and on-line services businesses, are likely to
encounter consolidation in the near future, which could result in increased
price and other competition in the industry.  Increased price or other
competition could erode DTG's market share and could have a material adverse
effect on its business, financial condition and results of operations.  There
can be no assurance that DTG will have the financial resources, technical
expertise, marketing and support capabilities or the expansion and acquisition
possibilities to continue to compete successfully in this or any market.

     CABLE TELEVISION COMPETITION.  Cable television competes for customers in
local markets with other providers of entertainment, news and information.  The
competitors in these markets include broadcast television and radio, newspapers,
magazines and other printed material, motion picture theaters, video cassettes
and other sources of information and entertainment, including directly
competitive cable television operations.

     Cable television service initially was offered as a means of improving
television reception in markets where terrain factors or distance from major
cities limited the availability of off-air television.  In some of the areas
served by cable television systems, a substantial variety of television
programming can be received off-air, including low-power UHF television
stations, which have 

                                       70
<PAGE>
 
increased the number of television signals in the country and provided off-air
television programs to limited local areas. The extent to which cable television
service is competitive depends upon a cable television system's ability to
provide, on a cost-effective basis, a greater variety of programming than that
available off-air or through other alternative delivery sources. Regulatory
changes also impact competition in the cable industry. Both the 1992 Cable Act
and the Telecommunications Act are designed to increase competition in the cable
television industry.

     There are alternative methods of distributing the same or similar video
programming offered by cable television systems.  Further, these technologies
have been encouraged by Congress and the FCC to offer services in direct
competition with existing cable systems.  A significant competitive impact is
expected from medium power and higher power direct broadcast satellites ("DBS")
that use high frequencies to transmit signals that can be received by dish
antennas much smaller in size than traditional home satellite dishes ("HSDs").
There are multiple DBS providers offering services in the United States.  These
services are generally available throughout the continental U.S., including
areas in which DTG operates its cable systems.

     DBS has both advantages and disadvantages as an alternative means of
distributing video signals to a customer's home.  Among the advantages are that:
(i) the capital investment (although initially high) for the satellite and
uplinking segment of a DBS system is fixed and does not increase with the number
of subscribers receiving satellite transmissions; (ii) DBS is not currently
subject to local regulation of service and prices or required to pay franchise
fees; and (iii) the capital costs for the ground segment of a DBS system (the
reception equipment) are directly related to, and limited by, the number of
service subscribers.  DBS's disadvantages presently include: (i) limited ability
to tailor the programming package to the interests of different geographic
markets, such as providing local news, other local origination services and
local broadcast stations; (ii) signal reception being subject to line-of-sight
angles; and (iii) intermittent interference from atmospheric conditions and
terrestrially generated radio frequency noise.

     Although the effect of competition from DBS services cannot be specifically
predicted, there has been significant growth in DBS subscribers and DTG
anticipates that such DBS competition will increase in the future as
developments in technology continue to increase satellite transmitter power,
decrease the cost and size of equipment needed to receive these transmissions
and enable DBS to overcome the disadvantages discussed above.  Further, the
extensive national advertising of DBS programming packages, including certain
sports packages not currently available on cable television systems, will likely
continue the rapid growth in DBS subscribers.

     The Telecommunications Act eliminated the statutory and regulatory
restrictions that prevented telephone companies from competing with cable
operators for the provision of video services.  The Telecommunications Act
allows local telephone companies, including RBOCs, to compete with cable
television operators both inside and outside of their telephone service areas.
DTG expects that it may face substantial competition from telephone companies
for the provision of video services, whether it is through the acquisition of
cable systems, the provision of wireless cable or the provision of upgraded
telephone networks.  Most major telephone companies have greater financial
resources than DTG, and the 1992 Cable Act ensures that telephone company
providers of video services will be able to acquire significant cable television
programming services.  The specific manner in which telephone company provision
of video services will be regulated is discussed later in this Prospectus and
Proxy Statement.  Additionally, the Telecommunications Act eliminates certain
federal restrictions on utility holding companies and thus permits all utility
companies to provide cable television services.  DTG expects that the
elimination of these federal restrictions could result in another source of
significant competition in the delivery of video services.

     Another alternative method of distributing cable television is multi-
channel, multi-point distribution systems ("MMDS"), which deliver programming
services over microwave channels received by subscribers with special antennas.
MMDS systems are less capital intensive, are not 

                                       71
<PAGE>
 
required to obtain local franchises or pay franchise fees and are subject to
fewer regulatory requirements than cable television systems. The 1992 Cable Act
also ensures that MMDS systems have the ability to provide all significant cable
television programming services. Although there are relatively few MMDS systems
in the United States currently in operation, virtually all markets have been
licensed or tentatively licensed.

     The FCC has taken a series of actions intended to facilitate the
development of wireless cable systems as an alternative means of distributing
video programming, including reallocating the use of certain frequencies to
these services and expanding the permissible use of certain channels reserved
for educational purposes.  The FCC's actions enable a single entity to develop
MMDS systems with a potential of up to 35 channels, which permits the MMDS
systems to compete more effectively with cable television.  Developments in
compression technology will significantly increase the number of channels that
MMDS can offer.  Further, in 1995, several large telephone companies acquired
significant ownership in numerous MMDS companies.  Recently, DTG has experienced
increased competition from an MMDS provider operating in several of DTG's
existing cable system communities.

     Within the cable television industry, cable operators may compete with
other cable operators or other entities seeking franchises for competing cable
television systems at any time during the terms of existing franchises or upon
expiration of such franchises in the expectation that an existing franchise will
not be renewed.  The 1992 Cable Act promotes the grant of competitive
franchises.  Furthermore, an increasing number of cities are exploring the
feasibility of owning their own cable systems in a manner similar to city-
provided utility services.

     Although there is no legal prohibition preventing long distance telephone
companies from providing video services, historically they have not provided
such services in competition with cable systems.  However, such companies may
prove to be a source of competition in the future.  The long distance companies
are expected to expand into local markets with local telephone and other
offerings (including video services) in competition with RBOCs, which under the
terms and conditions of the Telecommunications Act are permitted to enter the
long distance service market in their regions subject to satisfying certain
requirements.

     In addition to competition for subscribers, the cable television industry
competes for advertising revenue with broadcast television, radio, print media
and other sources of information and entertainment.  As the cable television
industry has developed additional programming, its advertising revenue has
increased.  Cable operators sell advertising spots primarily to local and
regional advertisers.  To date, DTG's advertising efforts have been limited to
local public service announcements due to the limited capabilities of its
existing systems.  DTG currently intends to expand its advertising efforts as it
completes the upgrade of many of its systems.

     DTG has no basis upon which to estimate the number of cable television
companies and other entities with which it competes or may potentially compete.
There are a large number of individual and multiple system cable television
operators in the United States that are capable of competing with DTG and that
have substantially greater financial, technological, marketing and other
resources.

     The full extent to which other media or home delivery services will compete
with cable television systems may not be known for some time and there can be no
assurance that existing, proposed or as yet undeveloped technologies will not
become dominant in the future.

     COMPUTER NETWORKING SERVICES.  The markets in which DTG operates its
computer integration business are also intensely competitive.  Barriers to entry
are generally very low and many different types of technical service providers
are attempting to enter the PC network market.  These competitors include
mainframe and mid-range computer manufacturers and outsourcers such 

                                       72
<PAGE>
 
as Digital Equipment Corporation, Electronic Data Systems Corporation, Hewlett-
Packard Company and IBM. Other competitors include regional value added
resellers, systems integrators and third-party service companies. DTG expects to
face further competition from new market entrants and possible alliances between
competitors in the future. Most of these competitors have greater financial,
technical, marketing and other resources than DTG and are therefore able to
respond more quickly to new or emerging technologies and changes in customer
requirements or to devote greater resources to the development, promotion and
sale of their products and services then DTG. There is no assurance that DTG
will be able to successfully compete against current and future competitors.

REGULATION

     OVERVIEW.  DTG operates in a highly regulated industry and its services are
subject to varying degrees of federal, state and local regulation.  The FCC
exercises jurisdiction over all facilities of, and services offered by,
telecommunications common carriers to the extent that they involve the
provision, origination or termination of interstate or international
communications.  The FCC also regulates many aspects of DTG's cable television
operations.  The South Dakota Public Utilities Commission retains jurisdiction
over DTG's telecommunications operations in South Dakota while other state
public utilities commissions regulate the intrastate aspects of DTG's long
distance business in their states.  Finally, certain cities and municipal
governments regulate by franchise DTG's cable television operations within their
jurisdictions.

     The regulation of the telecommunications industry is changing rapidly and
the regulatory environment varies substantially from state to state.  There can
be no assurance that recent or future regulatory changes will not have a
material adverse impact on DTG.  Recent developments include, without
limitation: (i) enactment of the Telecommunications Act which modifies the AT&T
Divestiture Decree restrictions on the provision of long distance services by
RBOCs between LATAs as defined in the AT&T Divestiture Decree; (ii) FCC and
state public utilities commission actions changing access rates charged by LECs
and making other related changes to access and interconnection policies, certain
of which could have adverse consequences for DTG's long distance and local
service businesses; (iii) related FCC and state regulatory proceedings
considering additional deregulation of LEC access pricing; and (iv) various
legislative and regulatory proceedings that would result in new local exchange
competition.

     As the following discussion illustrates, the regulation of the
telecommunications and cable industries at the federal, state and local levels
is subject to the political process and has been in constant flux over the past
decade.  Material changes in the law and regulatory requirements must be
anticipated and there can be no assurance that DTG's business will not be
affected adversely by future legislation, new regulation or deregulation.

     TELECOMMUNICATIONS ACT OF 1996.  On February 8, 1996, President Clinton
signed into law the Telecommunications Act.  Among other things, this
legislation: (i) permits RBOCs to provide domestic and international long
distance services in their own regions upon a finding that the petitioning RBOC
has satisfied certain criteria for opening up its local exchange network to
competition and that its provision of long distance services would further the
public interest; (ii) removes existing barriers to entry into local service
markets; (iii) significantly changes the manner in which carrier-to-carrier
interconnection arrangements are regulated at the federal and state level; and
(iv) establishes procedures to revise universal service standards.

     The Telecommunications Act has particular relevance to DTG in four areas.
First, the Telecommunications Act creates a duty on the part of DTG to
interconnect its networks with those of its competitors and, in particular,
creates a duty on the part of DTG's local exchange operations to negotiate in
good faith the terms and conditions of such interconnection.  On August 8, 1996,
the FCC released its FCC Interconnection Order.  In the FCC Interconnection
Order, the FCC adopted a 

                                       73
<PAGE>
 
national framework for interconnection but left to the individual states the
task of implementing the FCC's rules. Petitions for review of the FCC
Interconnection Order were consolidated before the United States Court of
Appeals for the Eighth Circuit, which on July 18, 1997 overturned substantial
parts of the FCC's order as it relates to the ability of the FCC to set
interconnection rates. The FCC has appealed the ruling to the Supreme Court,
which accepted the case and heard oral argument on October 13, 1998. A decision
is not expected before the end of 1998.

     Second, the Telecommunications Act contains a number of provisions that are
intended to reduce barriers to entry and promote competition in a variety of
telecommunications markets, including both long distance and local exchange
operations.  As a part of this effort, the Telecommunications Act provides a
framework under which RBOCs may enter the interexchange communications business
from which they were barred under the terms of the AT&T Divestiture Decree.
Under this framework, an RBOC may provide long distance services in the states
where it provides telephone service upon demonstrating to the affected state
regulatory authority and to the FCC that: (i) it faces competition for local
telephone service from at least one facilities-based competitor and (ii) that it
satisfies a 14 point checklist that would purport to show that the affected
RBOC's local exchange operations are open to competition.  The
Telecommunications Act establishes deadlines within which both the affected
state regulatory agency and the FCC must act upon applications filed by an RBOC
to enter the long distance business.  Certain of the RBOCs already have taken
steps to provide in-region long distance services and have filed applications
with the FCC seeking authority to provide such services in certain states.  DTG
expects that most or all of the RBOCs will file applications for authority to
provide in-region long distance service.  To date, the FCC has rejected each of
those applications, however.  The RBOCs can provide long distance services
immediately in other states and also, with certain restrictions, cellular, video
and incidental services.

     Third, although the Telecommunications Act generally prohibits long
distance companies from marketing their services jointly with local telephone
services provided by an RBOC (at least until that RBOC is permitted to enter the
long distance business in its own region), it contains an exception for
companies, such as DTG, that serve less than five percent of the nation's
presubscribed access lines.  Thus, the Telecommunications Act permits DTG to
continue to market its long distance services jointly with local telephone
services whether provided by DTG or provided by an RBOC or non-affiliated
company.

     Finally, the Telecommunications Act modifies certain of the regulations
governing DTG's cable television operations and addresses some of the issues
arising out of the combination of cable and telephone service.

     DTG cannot predict the effect that this legislation and the FCC's
implementing regulations, many of which are still forthcoming or subject to
judicial challenges, will have on DTG or the industry as a whole.  However, DTG
believes that it is positioned to pursue business opportunities in the rapidly
changing telecommunications market.

     LOCAL SERVICE REGULATION.  Historically, DTG's local telephone operations
have been governed by regulation and oversight of the South Dakota Public
Utilities Commission.  The South Dakota Public Utilities Commission has had
primary jurisdiction over various matters including intrastate toll and access
rates, quality of service, issuance of securities, depreciation rates,
disposition of public utility property, issuance of debt and accounting systems
used by DTG.  DTG has, however, been statutorily exempt from many of these
requirements by virtue of its size.  The FCC historically has had primary
jurisdiction over the interstate toll and access rates of DTG and issues related
to interstate telephone service.

     The Telecommunications Act has substantially modified both the states' and
the FCC's jurisdictions in the regulation of local exchange telephone companies.
The Telecommunications Act prohibits any state legislative or regulatory
restrictions or barriers to entry regarding the provision 

                                       74
<PAGE>
 
of local telephone service. The Telecommunications Act required the FCC to
develop regulations to implement various sections of the Telecommunications Act
including: (i) the obligations imposed on incumbent LECs to interconnect with
the networks of other telecommunications carriers (including competing
telecommunications carriers); (ii) unbundling of services into network elements;
(iii) repricing of their services at wholesale rates for the purpose of
permitting resale of those services; (iv) allowing other telecommunications
carriers physically to collocate their equipment on the premises of the
incumbent LEC; and (v) requiring telecommunications carriers to compensate each
other based on their own costs for the transport and termination of calls on the
other carriers' networks.

     As a rural telephone company, DTG is currently exempt from certain of the
foregoing obligations unless, in response to a bona fide request, the South
Dakota Public Utilities Commission removes that exemption.  DTG, by petitioning
the South Dakota Public Utilities Commission, also may qualify for exemption
from certain other obligations under the Telecommunications Act.  In addition,
pursuant to the Telecommunications Act, the FCC instituted and referred to a
federal-state joint board a proceeding to recommend changes to the current
method of subsidizing universal service to assure the availability of quality
telephone services at just, reasonable and affordable rates.  The federal-state
joint board released an initial "recommended decision" on November 8, 1996, and
on May 8, 1997, the FCC released a Report and Order substantially adopting the
Joint Board's recommendations.  Appeals of the FCC's Report and Order have been
consolidated before the United States Court of Appeals for the Fifth Circuit and
currently are pending.  On October 28, 1998, the FCC released its Fifth Report
and Order establishing a universal service support mechanism for non-rural
carriers based on the forward-looking economic cost of constructing and
operating the network used to provide the supported services.  The FCC also is
considering the establishment of forward-looking economic cost mechanisms for
rural carriers.  Non-rural carriers would begin to receive support based on
forward-looking economic cost on January 1, 1999, whereas rural carriers would
shift to such an approach beginning no sooner than January 1, 2001.  DTG cannot
predict the terms or the effect that the FCC's actions will have on DTG or on
the industry as a whole.  However, DTG believes that it is taking proper steps
to reduce its exposure to potential declines in universal service support.

     The Telecommunications Act requires that all telecommunications carriers
that provide interstate telecommunications services (including cable operators
that provide telecommunications services) contribute equitably to a universal
service fund ("USF"), although the FCC may exempt an interstate carrier or class
of carriers if their contribution would be minimal under the USF formula.  The
Telecommunications Act allows states to determine which intrastate
telecommunications providers contribute to the USF.  The purpose of the USF is
to provide consumers in all regions, including low-income consumers and those
consumers in rural, insular and high-cost areas, access to telecommunications
and information services that are reasonably comparable to those services in
urban areas at reasonably comparable rates.  DTG is a contributor to, and a
recipient of, USF funds.  DTG currently anticipates that it will receive more
from USF funding than it will contribute.

     NETWORK ACCESS REGULATION.  DTG is subject to the jurisdiction of the FCC
with respect to its provision of interstate network access services and certain
related services.  The FCC prescribes a uniform system of accounts for telephone
companies, interstate depreciation rates and the principles and standard
procedures used to separate plant investment, expenses, taxes and reserves of
interstate services under the jurisdiction of the FCC and of intrastate services
under the jurisdiction of the respective state regulatory authorities
("separations procedures").  The FCC also prescribes procedures for allocating
costs and revenues between regulated and unregulated activities.  A proceeding
to review separations reform currently is pending before the FCC.

     The FCC has prescribed structures for exchange access tariffs to specify
the access charges for use and availability of DTG's facilities for the
origination and termination of interstate long distance service.  In general,
the tariff structures prescribed by the FCC provide that interstate costs 

                                       75
<PAGE>
 
which do not vary based on usage ("non-traffic sensitive costs") are recovered
from subscribers through flat monthly charges ("subscriber line charges") and
from IXCs through usage-sensitive Carrier Common Line ("CCL") charges. Traffic-
sensitive interstate costs are recovered from carriers through variable access
charges based on several factors, primarily usage.

     On December 24, 1996, the FCC initiated a rulemaking proceeding to address
access charge reform.  On May 16, 1997, the FCC released its First Report and
Order adopting changes to the existing access charge structure.  With limited
exceptions, those modifications apply only to price cap incumbent LECs, which
generally are the nation's largest telephone companies.  The FCC also has issued
several orders to provide additional rules to implement access charge reform and
has initiated separate proceedings to examine historical cost recovery issues
and access charge reform for rate-of-return carriers, such as DTG.  Appeals of
the FCC's First Report and Order were consolidated before the Eighth Circuit
which on August 18, 1998 affirmed the FCC.  The FCC is continuing to review and
amend its rules in this area and there can be no assurance that the FCC will not
adopt rules that would have a material adverse effect on DTG.

     The FCC authorizes a rate-of-return ("ROR") that telephone companies such
as DTG may earn on the interstate services they provide.  The current ROR is
11.25% for companies remaining under ROR regulation.  The FCC is currently
considering changing the 11.25% ROR as a result of lower market interest rates.
Effective January 1, 1991, the FCC replaced ROR regulation with price-cap
regulation for the RBOCs and GTE Corporation and allowed all other companies
that did not remain in the National Exchange Carrier Association ("NECA") Common
Line and Traffic Sensitive Pools the option of price-cap regulation.  DTG, like
most small local exchange carriers, has elected to remain within the NECA tariff
scheme.

     In 1992, the FCC initiated a rulemaking proceeding (CC Docket No. 92-135)
to address regulatory alternatives for mid-size and small LECs.  This proceeding
resulted in rules, adopted in September 1993, that provide for a non-price cap
form of alternative regulation.  DTG would be eligible for this form of
regulation.  DTG has not elected price cap regulation for interstate purposes
and continues to evaluate the various forms of alternative regulation.

     The effect of the Telecommunications Act on the FCC's regulations
concerning ROR regulation and alternative regulation is not yet clear, although,
as a result of the enactment of the Telecommunications Act, the FCC is
reexamining its rules to reflect the provisions of the Telecommunications Act.

     The Telecommunications Act requires each LEC to continue to provide access
services in accordance with requirements effective on the date immediately
preceding the effective date of the Telecommunications Act, until those
requirements are specifically superseded by FCC regulations.  Pursuant to the
Telecommunications Act, the FCC established regulations to implement the
interconnection, unbundled access, resale and collocation requirements of the
Telecommunications Act.  The Telecommunications Act requires that
interconnection and unbundled network elements be priced at just and reasonable
rates based on costs and that compensation for transport and termination of
traffic be reciprocal among carriers and be just and reasonable.

     In addition to the matters discussed above, FCC rules also govern:  (i) the
allocation of costs between the regulated and unregulated activities of a
communications common carrier and (ii) transactions between the regulated and
unregulated affiliates of a communications common carrier.

     The cost allocation rules apply to certain activities that have never been
regulated as communications common carrier offerings and to activities that have
been preemptively deregulated by the FCC.  The costs of these activities are
removed prior to the separations procedures process and are assigned to
unregulated activities in the aggregate, rather than to specific services, for

                                       76
<PAGE>
 
pricing purposes. Other activities must be accounted for as regulated
activities, and their costs are subject to separations procedures.

     The affiliate transaction rules govern the pricing of assets transferred to
and services provided by affiliates.  These rules generally require that assets
be transferred between affiliates at "market price," if such price can be
established through a tariff or a prevailing price actually charged to third
parties.  In the absence of a tariff or prevailing price, "market price" cannot
be established, in which case: (i) asset transfers from a regulated to an
unregulated affiliate must be valued at the higher of cost or fair market value
and (ii) asset transfers from an unregulated to a regulated affiliate must be
valued at the lower of cost or fair market value.  DTG prices transactions to
and between its subsidiaries at cost where appropriate and at fair market value
where appropriate.

     The FCC has not attempted to make its cost allocation or affiliate
transaction rules preemptive.  State regulatory authorities are free to use
different cost allocation methods and affiliate transaction rules for intrastate
rate-making and to require carriers to keep separate allocation records.

     DTG's local and intrastate operations are regulated by the South Dakota
Public Utilities Commission.  Like many state regulatory authorities, the South
Dakota Public Utilities Commission is conducting proceedings concerning the
rules under which carriers may operate in an increasingly competitive
environment.  The issues that the South Dakota Public Utilities Commission is
examining include unbundling and interconnection, dialing parity for intra-LATA
(or short-haul) toll traffic, number portability, resale of local exchange
service and universal service.  The Telecommunications Act has begun to have an
effect on the timing and outcome of proceedings in many states, including South
Dakota.  DTG actively monitors the South Dakota proceedings as well as the
proceedings in other states.  However, DTG cannot, at this time, predict how
these proceedings will ultimately be resolved and their effect on DTG or when a
decision will be forthcoming.

     DTG's telephone operating subsidiaries currently receive compensation from
long distance companies for intrastate long distance services through access
charges or toll settlements that are subject to state regulatory commission
approval.  The South Dakota Public Utilities Commission approved an intrastate
access rate increase for DTG effective December 10, 1996.  There are no rate
requests of DTG currently pending before any regulatory commission.

     LONG DISTANCE REGULATION.  The FCC has classified DTG as a non-dominant IXC
for purposes of all long distance operations conducted outside of its existing
local service exchanges. As a non-dominant carrier, DTG may provide domestic
interstate communications in these areas without prior FCC authorization,
although FCC authorization is required for the provision of international
telecommunications by non-dominant carriers. Generally, the FCC has chosen not
to exercise its statutory power to closely regulate the charges or practices of
non-dominant carriers.  Nevertheless, non-dominant carriers are required by
statute to offer interstate and international services under rates, terms and
conditions that are just, reasonable and not unduly discriminatory, and the FCC
acts upon complaints against such carriers for failure to comply with statutory
obligations or with the FCC's rules, regulations and policies.  The FCC also has
the power to impose more stringent regulatory requirements on DTG and to change
its regulatory classification, although DTG believes that, in the current
regulatory environment, the FCC is unlikely to do so.

     Historically, both domestic and international non-dominant long distance
carriers maintained tariffs on file with the FCC. Pursuant to this requirement,
DTG filed and maintained with the FCC a tariff for its interstate and
international services.  DTG also has obtained FCC authority to provide
international services through the resale of switched services of various
carriers.  On March 21, 1996, the FCC initiated a rulemaking proceeding in which
it proposed to eliminate the requirement that non-dominant interstate carriers,
such as DTG, maintain tariffs on file with the 

                                       77
<PAGE>
 
FCC for domestic interstate services. On October 29, 1996, the FCC announced
that, following a nine-month transition period, long distance carriers were no
longer required to file tariffs for interstate domestic long distance service,
and that the relationship between carriers and their customers would be governed
by individual contracts. Carriers also had the option immediately to cease
filing tariffs. DTG did not elect to cease filing interstate tariffs. Following
a judicial stay of the FCC's detariffing order, the FCC on March 6, 1997,
released a public notice stating that the tariffing rules in place prior to
December 22, 1996, were once again in effect. Thus, nondominant carriers
providing interstate, domestic interexchange services, such as DTG, continue to
be required to file tariffs pursuant to the FCC's rules.

     The FCC also imposes prior approval requirements on transfers of control
and assignments of operating authorizations.  The FCC has the authority to
generally condition, modify, cancel, terminate or revoke operating authority for
failure to comply with federal laws and/or the rules, regulations and policies
of the FCC.  Fines or other penalties also may be imposed for such violations.
Although DTG believes that it has complied in all material respects with
applicable laws and regulations, there can be no assurance that the FCC or third
parties will not raise issues with regard to DTG's compliance with applicable
laws and regulations.

     The intrastate long distance telecommunications operations of DTG also are
subject to various state laws and regulations, including certification
requirements.  Generally, DTG must obtain and maintain certificates of public
convenience and necessity from regulatory authorities as well as file tariffs in
most states in which it offers intrastate long distance services and, in most of
these jurisdictions, also must file and obtain prior regulatory approval of
tariffs for its intrastate offerings.  Many states also impose various reporting
requirements and/or require prior approval for transfers of control of certified
carriers and/or for: corporate reorganizations; acquisitions of
telecommunications operations; assignments of carrier assets, including
subscriber bases; carrier stock offerings; and incurrence by carriers of
significant debt obligations.  Certificates of authority can generally be
conditioned, modified, canceled, terminated or revoked by state regulatory
authorities for failure to comply with state law and/or the rules, regulations
and policies of the state regulatory authorities.  Fines and other penalties
also may be imposed for such violations.

     At the present time, DTG is authorized to provide originating long distance
services to customers in all states except Alaska and Hawaii.  Those services
may terminate in any state in the United States and may also terminate in
countries abroad.  Only 31 states have public utility commissions that actively
assert regulatory oversight over intrastate services such as those currently
offered by DTG.  Like the FCC, many of these regulating jurisdictions are
relaxing the regulatory restrictions currently imposed on telecommunications
carriers for intrastate service.  While some of these states restrict the
offering of intra-LATA services by DTG and other IXCs, the general trend is
toward opening up these markets to DTG and other IXCs.  Those states that permit
the offering of intra-LATA services by IXCs generally require that end-users
desiring to access these services dial special access codes which place DTG and
other IXCs at a disadvantage as compared to LEC intra-LATA toll service which
generally requires no access code.

     WIRELESS SERVICES.  DTG, through its wholly owned subsidiary, Dakota
Wireless Systems, Inc. ("DWS"), had a Spectrum Agreement with U S WEST Wireless
for participation in the FCC's PCS D- and E-Block spectrum auction.  This
auction concluded on January 14, 1997, with U S WEST Wireless being the
successful bidder on BTA-421 (Sioux City) for the E-Block at $2.44 per
population point.  DTG's agreement covers 104,900 population points in DTG's
area of interest in Southeastern South Dakota and Northwestern Iowa outside of
the municipal boundaries of Sioux City.  DTG has a total investment of $255,956
in these licenses.  DTG has entered into negotiations with U S WEST Wireless for
additional portions of the BTA, but there is no assurance that these
negotiations will be successful for DTG.

                                       78
<PAGE>
 
     The licensing, construction, operation, acquisition and sale of wireless
networks, as well as the number of PCS, cellular and other wireless licensees
permitted in each market, are regulated by the FCC.  Federal law prohibits the
states from regulating the rates charged by wireless telecommunications carriers
(including PCS and cellular).  Although some states have petitioned the FCC for
authority to regulate wireless rates, thus far no such petitions have been
successful.  Federal law also expressly prohibits the states from regulating the
entry of wireless carriers.  However, to the extent not otherwise preempted, the
states are permitted to regulate any other terms and conditions of wireless
services, including but not limited to customer billing information and
practices; consumer protection matters; bundling of service and equipment;
availability of wholesale capacity; and facilities siting issues.  There can be
no assurance that state agencies having jurisdiction over DTG's business will
not adopt regulations, impose taxes on PCS licenses or take other actions that
would adversely affect the business of DTG.  Federal and state regulators also
will determine important aspects of DTG's operations, such as technical aspects
of and payments for interconnection with landline and other wireless networks.

     On July 26, 1996, the FCC released a report and order establishing
timetables for making emergency 911 services available by PCS and other mobile
services providers, including "enhanced 911" services that provide the caller's
telephone number, location and other useful information.  In several subsequent
orders, the FCC has modified its requirements and postponed the deadlines for
compliance.  Upon implementation of the requirements, PCS providers must be able
to process and transmit 911 calls (without call validation), including those
from callers with speech or hearing disabilities.  Providers must also be able
to relay a caller's automatic number identification and cell site, and by 2001
they must be able to identify the location of a 911 caller within 125 meters in
67% of all cases.  State actions incompatible with these FCC rules are subject
to preemption.  Various parties have petitioned the FCC to reconsider certain
requirements imposed in the order and in subsequent proceedings.

     On August 1, 1996, the FCC released a report and order expanding the
flexibility of PCS and other commercial mobile radio services to provide fixed
as well as mobile services.  Such fixed services include, but need not be
limited to, "wireless local loop" services and wireless backup of private branch
exchanges ("PBXs") and local area networks, to be used in the event of
interruptions due to weather or other emergencies.  A petition for
reconsideration or clarification of aspects of the FCC's order presently is
pending.

     The FCC limits the aggregate amount of spectrum in which a licensee may
have an attributable interest.  In general, licensees in the PCS, cellular or
specialized mobile radio ("SMR") services may not have an attributable interest
in a total of more than 45 MHz of PCS, cellular and SMR spectrum in a geographic
area.  On November 19, 1998, the FCC adopted a Notice of Proposed Rulemaking to
reevaluate the need for the spectrum aggregation limit.

     DTG must obtain a number of approvals, licenses and permits for the
operation of its wireless paging and mobile radio business, including land use
regulatory approvals and licenses from the Federal Aviation Administration in
connection with its PCS towers.  Additionally, the wireless telecommunications
industry is subject to certain state and local governmental regulations.
Operating costs also are affected by other government actions that are beyond
DTG's control.  There is no assurance that the various federal, state and local
agencies responsible for granting such licenses, approvals and permits will do
so or that, once granted, those agencies will not revoke or fail to renew them.
Failure to obtain such licenses, approvals and permits would adversely affect,
delay commencement of or prohibit certain business operations proposed by DTG.

     CABLE TELEVISION REGULATION.  The operation of cable television systems is
extensively regulated through a combination of federal legislation and FCC
regulations, by some state governments and by most local government franchising
authorities such as municipalities and counties.  The Telecommunications Act
also affected the regulation of cable television operations. The 

                                       79
<PAGE>
 
new law alters federal, state and local laws and regulations regarding
telecommunications providers and cable television service providers, including
DTG. The discussion below summarizes the relevant provisions of the
Telecommunications Act and reviews the pre-existing federal cable television
regulation as revised by the Telecommunications Act.

     THE TELECOMMUNICATIONS ACT OF 1996.  The following is a summary of certain
provisions of the Telecommunications Act which could materially affect the
growth and operation of the cable television industry and the cable and
telecommunications services provided by DTG.  The FCC has undertaken, and
continues to undertake, numerous rulemaking proceedings to interpret and
implement the provisions discussed below.  It is not possible at this time to
predict the effects of such rulemaking proceedings on DTG.

     CABLE RATE REGULATION.  Rate regulation of DTG's cable television services
is divided between the FCC and local units of government, primarily the local
municipalities in which DTG provides services.  The FCC's jurisdiction extends
to the cable programming service tier ("CPST"), which consists largely of
satellite-delivered programming (excluding basic tier programming and
programming offered on a per-channel or per-program basis).  Local units of
government (commonly referred to as "local franchising authorities" or "LFAs")
are primarily responsible for regulating rates for the basic tier of cable
service ("BST"), which typically will contain at least the local broadcast
stations and public access, educational and government ("PEG") channels.
Equipment rates are also regulated by LFAs.  The FCC retains appeal jurisdiction
from LFA decisions.  Cable services offered on a per-channel or per-program-only
basis remain unregulated.  By virtue of its small size, DTG is currently exempt
from these regulations.

     Because of DTG's rate structure and small size, there is no CPST regulation
of DTG's rates at the current time.  If DTG's cable operations were to increase
above the thresholds established in 1996 or if DTG were to change its rate
structure with respect to cable services, additional regulations may apply.
Those additional regulations would include, through March 31, 1999,  CPST rate
regulations, which would be triggered only by an LFA complaint.  An LFA
complaint must be based upon more than one subscriber complaint.  Prior to the
Telecommunications Act, an FCC review of CPST rates could be occasioned by a
single subscriber complaint to the FCC.  The Telecommunications Act does not
disturb existing or pending CPST rate settlements between DTG and the FCC.
DTG's BST rates remain subject to LFA regulation under the Telecommunications
Act.  Existing law precludes rate regulation wherever a cable operator faces
effective competition.  The Telecommunications Act expands the definition of
effective competition to include any franchise area where a LEC (or affiliate)
provides video programming services to subscribers by any means other than
through direct broadcast satellite service.  There is no penetration minimum for
the LEC to qualify as an effective competitor, but it must provide comparable
programming services (12 channels including some broadcast channels) in the
franchise area.  By virtue of its small size, DTG is currently exempt from most
of these requirements.

     Under the Telecommunications Act, DTG will be allowed to aggregate on a
franchise, system, regional or company level its equipment costs into broad
categories, such as converter boxes, regardless of the varying levels of
functionality of the equipment within each such broad category.  The
Telecommunications Act allows DTG to average together costs of different types
of converters including non-addressable, addressable and digital.  The statutory
changes will also facilitate the rationalizing of equipment rates across
jurisdictional boundaries.  These cost-aggregation rules do not apply to the
limited equipment used by "BST-only" subscribers.

     CABLE UNIFORM RATE REQUIREMENTS.  The Telecommunications Act immediately
relaxes the uniform rate requirements of the 1992 Cable Act by specifying that
such requirements do not apply where the operator faces effective competition,
and by exempting bulk discounts to multiple dwelling units, although complaints
regarding predatory pricing may be made to the FCC.  Upon a prima 

                                       80
<PAGE>
 
facie showing that there are reasonable grounds to believe that the discounted
price is predatory, the cable system operator will have the burden of proving
otherwise.

     DEFINITION OF CABLE SYSTEM.  The Telecommunications Act changes the
definition of a cable system so that competitive providers of video services
will only be regulated and franchised as a cable system if they use public
rights-of-way.

     CABLE POLE ATTACHMENTS.  Under the Telecommunications Act, investor-owned
utilities must make poles and conduits available to cable systems under
delineated terms.  Electric utilities are given the right to deny access to
particular poles on a nondiscriminatory basis for lack of capacity, safety,
reliability and generally accepted engineering purposes.  On March 14, 1997, the
FCC released a notice of proposed rulemaking to amend its rules and policies
governing pole attachments.  In its notice, the FCC proposed a new formula for
determining rates applicable to attachments on poles, within ducts, conduits or
rights-of-way by both cable systems and telecommunications carriers until a
separate methodology is proposed for telecommunications carriers.  In the
Telecommunications Act, Congress directed the FCC to issue a new pole attachment
formula relating to telecommunications carriers within two years of the
effective date of the Telecommunications Act, to become effective five years
after enactment.  On February 6, 1998, the FCC released a Report and Order
implementing a methodology for determining pole attachment rates for
telecommunications carriers.  Those rules will result in higher pole rental
rates for cable operators.  Any increases pursuant to this formula may not begin
for five years and will be phased-in in equal increments over the fifth through
the tenth years.  This new FCC formula does not apply in states which certify
that they regulate pole rents.  Pole owners must impute pole rentals to
themselves if they offer telecommunications or cable services.  Cable operators
need not pay future make-ready on poles currently contracted if the make-ready
is required to accommodate the attachments of another user, including the pole
owner.

     CABLE ENTRY INTO TELECOMMUNICATIONS.  The Telecommunications Act declares
that no state or local laws or regulations may prohibit or have the effect of
prohibiting the ability of any entity to provide any interstate or intrastate
telecommunications service.  States are authorized to impose competitively
neutral requirements regarding universal service, public safety and welfare,
service quality and consumer protection.  The Telecommunications Act further
provides that cable operators and affiliates providing telecommunications
services are not required to obtain a separate franchise from LFAs for such
services.  The Telecommunications Act prohibits LFAs from requiring cable
operators to provide telecommunications service or facilities as a condition of
a grant of a franchise, franchise renewal or franchise transfer, except that
LFAs can seek institutional networks as part of such franchise negotiations.
The Telecommunications Act clarifies that traditional cable franchise fees may
only be based on revenues related to the provision of cable television services.
However, when cable operators provide telecommunications services, LFAs may
require reasonable, competitively neutral compensation for management of the
public rights-of-way.

     To facilitate the entry of new telecommunications providers (including
cable operators), the Telecommunications Act imposes interconnection obligations
on all telecommunications carriers.  All carriers must interconnect their
networks with other carriers and may not deploy network features and functions
that interfere with interoperability.  Existing LECs also have the following
obligations:  (i) good faith negotiation with carriers seeking interconnection;
(ii) unbundling, equal access and non-discrimination requirements; (iii) resale
of services, including resale at wholesale rates (with an exception for certain
low-priced residence services to business customers); (iv) notice of changes in
the network that would affect interconnection and interoperability; and (v)
physical collocation unless the LEC demonstrates that practical technical
reason, or space limitation, make physical collocation impractical.  The
Telecommunications Act also directs the FCC, within one year of enactment, to
adopt regulations for existing LECs to share infrastructure with qualifying
carriers, and the FCC released those regulations on February 7, 1997.  Under the
Telecommunications Act, individual interconnection rates must be just and
reasonable, based on cost, and may include a 

                                       81
<PAGE>
 
reasonable profit. Cost of interconnection will not be determined in an ROR
proceeding. Traffic termination charges shall be mutual and reciprocal. The
Telecommunications Act contemplates that interconnection agreements will be
negotiated by the parties and submitted to a state public utilities commission
for approval. A public utilities commission may become involved, at the request
of either party, if negotiations fail. If the state regulator refuses to act,
the FCC may determine the matter. If the public utilities commission acts, an
aggrieved party's remedy is to file a case in federal district court.

     TELEPHONE COMPANY ENTRY INTO CABLE TELEVISION.  The Telecommunications Act
allows telephone companies to compete directly with cable operators by repealing
the previous telephone company/cable cross-ownership ban and the FCC's video
dialtone regulations.  This will allow LECs, including the RBOCs, to compete
with cable operators both inside and outside of their telephone service areas.
If a LEC provides video via radio waves, it is subject to broadcast
jurisdiction.  If a LEC provides common carrier channel service it is subject to
common carrier jurisdiction.  A LEC providing video programming to subscribers
is otherwise regulated as a cable operator (including franchising, leased access
and customer service requirements), unless the LEC elects to provide its
programming via an open video system.  LEC owned programming services will also
be fully subject to program access requirements.

     The Telecommunications Act replaces the FCC's video dialtone rules with an
open video system ("OVS") plan by which LECs can provide cable service in their
telephone service area.  LECs complying with the FCC OVS regulations will
receive relaxed oversight.  The Telecommunications Act requires the FCC to act
on any such OVS certification within 10 days of its filing.  Only the program
access, negative option billing prohibition, subscriber privacy, PEG, must-carry
and retransmission consent provisions of the Communications Act of 1934, as
amended, will apply to LECs providing OVS.  Franchising, rate regulation,
consumer service provisions, leased access and equipment compatibility will not
apply.  Cable copyright provisions will apply to programmers using OVS.  LFAs
may require OVS operators to pay franchise fees only to the extent that the OVS
provider or its affiliates provide cable services over the OVS.  OVS operators
will be subject to LFA general right-of-way management regulations.  Such fees
may not exceed the franchise fees charged to cable operators in the area, and
the OVS provider may pass through the fees as a separate subscriber bill item.

     The FCC has adopted regulations prohibiting an OVS operator from
discriminating among programmers and ensuring that OVS rates, terms and
conditions for service are reasonable and nondiscriminatory.  Further, the FCC
has adopted regulations prohibiting a LEC-OVS operator, or its affiliates, from
occupying more than one-third of the system's activated channels when demand for
channels exceeds supply, although there are no numeric limits.  The
Telecommunications Act also mandates OVS regulations governing channel sharing,
extending the FCC's sports exclusivity, network nonduplication and syndicated
exclusivity regulations and controlling the positioning of programmers on menus
and program guides.  The Telecommunications Act does not require LECs to use
separate subsidiaries to provide incidental inter-LATA video or audio
programming services to subscribers or for their own programming ventures.  The
validity of the FCC's rules currently is under review in consolidated cases
pending before the United States Court of Appeals for the Fifth Circuit.

     While there remains a general prohibition on LEC buyouts of cable systems
(any ownership interest exceeding 10%), cable operator buyouts of LEC systems
and joint ventures between cable operators and LECs in the same market, the
Telecommunications Act provides exceptions to this prohibition.  A rural
exception permits buyouts where the purchased system serves an area with fewer
than 35,000 inhabitants outside an urban area.  Where a LEC purchases a cable
system, that system, in addition to any other system in which the LEC has an
interest, may not serve 10% or more of the LEC's telephone service area.
Additional exceptions are also provided for similar buyouts.  The
Telecommunications Act also provides the FCC with the power to grant waivers of
the 

                                       82
<PAGE>
 
buyout provisions in cases where: (i) the cable operator or LEC would be subject
to undue economic distress; (ii) the system or facilities would not be
economically viable; or (iii) the anticompetitive effects of the proposed
transaction are clearly outweighed by the effect of the transaction in meeting
community needs. The LFA must approve any such waiver.

     ELECTRIC UTILITY ENTRY INTO TELECOMMUNICATIONS/CABLE TELEVISION.  The
Telecommunications Act provides that registered utility holding companies and
subsidiaries may provide telecommunications services (including cable
television) notwithstanding the Public Utilities Holding Company Act.  Electric
utilities must establish separate subsidiaries, known as exempt
telecommunications companies, and must apply to the FCC for operating authority.
DTG anticipates that large utility holding companies will become significant
competitors to both cable television and other telecommunications providers as a
result of the Telecommunications Act.

     CROSS-OWNERSHIP AND MUST CARRY.  The Telecommunications Act eliminates
broadcast/cable cross-ownership restrictions (including broadcast network/cable
restrictions) but leaves in place FCC regulations prohibiting local cross-
ownership between television stations and cable systems.  The FCC is empowered
by the Telecommunications Act to adopt rules to ensure carriage, channel
positioning and non-discriminatory treatment of non-affiliated broadcast
stations by cable systems affiliated with a broadcast network.  Previous
satellite master antenna television ("SMATV") and MMDS cable cross-ownership
restrictions have been eliminated for cable operators subject to effective
competition.  By virtue of its small size, DTG is currently exempt from these
regulations.  The Telecommunications Act preserves local television
broadcasters' rights to signal carriage on cable systems ("must-carry") and
clarifies that the geographic scope of must-carry is to be based on commercial
publications which delineate television markets based on viewing patterns.  The
FCC is directed to grant or deny must-carry requests within 120 days of a
complaint being filed with the FCC.

     CABLE EQUIPMENT COMPATIBILITY AND SCRAMBLING REQUIREMENTS.  The
Telecommunications Act directed the FCC to establish an equipment comparability
rule emphasizing that: (i) narrow technical standards, mandating a minimum
degree of common design among televisions, VCRs and cable systems, and relying
heavily on the open marketplace, should be pursued; (ii) competition for all
converter features unrelated to security descrambling should be maximized; and
(iii) adopted standards should not affect unrelated telephone and computer
features.  Pursuant to the Telecommunications Act, the FCC has adopted
regulations which assure the competitive availability of converters ("navigation
devices") from vendors other than cable operators without impinging upon signal
security concerns or theft of service protections.  Waivers from these
requirements will be available if the cable operator shows the waiver is
necessary for the introduction of new services.  Once the equipment market
becomes competitive, FCC regulations in this area will be terminated.

     The Telecommunications Act requires cable operators, upon subscriber
request, to fully scramble or block at no charge the audio and video portion of
any channel not specifically subscribed to by a household.  Further, the
Telecommunications Act provides that sexually explicit programming must be fully
scrambled or blocked.  If the cable operator cannot fully scramble or block its
signal, it must restrict transmission to those hours of the day when children
are unlikely to view such programming.

     PRE-EXISTING FEDERAL REGULATION.  The 1984 Cable Act and the 1992 Cable Act
regulated the cable television industry and the vast majority of that regulation
remains unchanged by the Telecommunications Act.  The 1984 Cable Act created
uniform national standards and guidelines for the regulation of cable systems.
Among other things, the 1984 Cable Act generally preempted local control over
cable rates in most areas.  In addition, the 1984 Cable Act affirmed the right
of a franchising authority (state or local, depending on the practice in
individual states) to award one or more franchises within its jurisdiction.  It
also prohibited non-grandfathered cable systems from 

                                       83
<PAGE>
 
operating without a franchise in such jurisdiction. The 1984 Cable Act: (i)
requires cable television systems with 36 or more activated channels to reserve
a percentage of such channels for commercial use by unaffiliated third parties;
(ii) permits franchise authorities to require the cable operator to provide
channel capacity, equipment and facilities for public, educational and
governmental access; and (iii) regulates the renewal of franchises.

     The 1992 Cable Act greatly expanded federal and local regulation of the
cable television industry.  Certain of the more significant areas of regulation
imposed by the 1992 Cable Act are discussed below.

     REGULATION OF PROGRAM LICENSING.  The 1992 Cable Act directed the FCC to
issue regulations regarding the sale and acquisition of cable programming
between multichannel video program distributors (including cable operators) and
programming services in which a cable operator has an attributable interest.
The legislation and the implementing regulations adopted by the FCC preclude
most exclusive programming contracts (unless the FCC first determines the
contract serves the public interest) and generally prohibit a cable operator
that has an attributable interest in a programmer from improperly influencing
the terms and conditions of sale to unaffiliated multichannel video program
distributors.  Further, the 1992 Cable Act requires that such cable affiliated
programmers make their programming services available to cable operators and
competing video technologies such as MMDS and DBS, and to telephone company
providers of video services, on terms and conditions that do not unfairly
discriminate among such competitors.

     REGULATION OF CARRIAGE OF PROGRAMMING.  Under the 1992 Cable Act, the FCC
adopted regulations prohibiting cable operators from requiring a financial
interest in a program service as a condition to carriage of such service,
coercing exclusive rights in a programming service or favoring affiliated
programmers so as to restrain unreasonably the ability of unaffiliated
programmers to compete.

     REGULATION OF CABLE SERVICE RATES.  The 1992 Cable Act subjected DTG's
cable systems to rate regulation, except in those cases where they face
"effective competition."  The FCC was required to establish standards and
procedures governing regulation of rates for basic cable service, equipment and
installation, which were then to be implemented by state and local franchising
authorities.  The 1992 Cable Act also required the FCC, upon complaint from a
franchising authority or a cable subscriber, to review the reasonableness of
rates for CPSTs.  The Telecommunications Act amended the 1992 Cable Act to allow
only LFAs to file complaints.  Services offered on an individual basis, such as
pay television and pay-per-view services, were not subject to rate regulation.

     On April 1, 1993, the FCC adopted rate regulations governing virtually all
cable systems, which were revised on February 22, 1994.  Under these
regulations, existing basic and CPST service rates typically are evaluated
against benchmark rates established by the FCC and are subject to mandatory
reductions.  Equipment and installation charges are regulated based on actual
costs.  As noted above, the Telecommunications Act provides that rate regulation
of the CPST automatically sunsets on March 31, 1999.

     The FCC also allowed cable operators to elect to justify rates under cost-
of-service rules, which allow high cost systems to establish rates in excess of
the benchmark level.  The FCC's interim cost-of-service rules allowed a cable
operator to recover, through rates for regulated cable services, its normal
operating expenses plus a rate of return equal to 11.25% on the rate base.
However, the FCC significantly limited the inclusion in the rate base of
acquisition costs in excess of the book value of tangible assets.  As a result,
DTG pursued cost-of-service justifications in only a few cases.  On December 15,
1995, the FCC adopted slightly more favorable cost-of-service rules.

     The FCC's rate regulations generally permit cable operators to adjust rates
to account for inflation and increases in certain external costs, including
programming costs, to the extent such 

                                       84
<PAGE>
 
increases exceed the rate of inflation. However, a cable operator may pass
through increases in the cost of programming services affiliated with such cable
operator, to the extent such costs exceed the rate of inflation only if the
price charged by the programmer to the affiliated cable operator reflects either
prevailing prices offered in the marketplace by the programmer to unaffiliated
third parties or the fair market value of the programming. The FCC's revised
regulations confirm that increases in pole attachment fees ordinarily will not
be accorded external cost treatment. The FCC recently adopted a method for
recovering external costs and inflation on an annual basis. The new method
minimizes the need for frequent rate adjustments and the regulatory lag problems
associated with the previous rate adjustment methodology.

     The regulations also provide mechanisms for adjusting rates when regulated
tiers are affected by channel additions or deletions.  Additional programming
costs resulting from channel additions can be accorded the same external
treatment as other programming costs increases, and cable operators presently
are permitted to recover a mark-up on their programming expenses.  Under one
option, operators were allowed a flat fee increase ($.20) per channel added to
an existing CPST, with an aggregate cap on such increases ($1.20) plus a license
fee reserve ($.30) through 1996.  In 1997, an additional flat fee increase
($.20) was available, and the license fees for additional channels and for
increases in existing channels were no longer subject to the aggregate cap. This
optional approach for adding services expired on December 31, 1997.

     The FCC adopted additional rules that permit channels of new programming
services to be added to cable systems in a separate new product tier which the
FCC has determined that it will not rate regulate at this time.  The FCC also
has adopted rules allowing operators to raise rates based on costs incurred in
connection with a substantial upgrade of the cable system.  The FCC provided
additional rate relief for small operators, including DTG, and to any additional
systems that DTG acquires to the extent that the systems are already eligible
for this favorable treatment.

     REGULATION OF CUSTOMER SERVICE.  As required by the 1992 Cable Act, the FCC
has adopted comprehensive regulations establishing minimum standards for
customer service and technical system performance.  Local franchising
authorities are allowed to enforce stricter customer service requirements than
the FCC standards.

     REGULATION OF CARRIAGE OF BROADCAST STATIONS.  The 1992 Cable Act granted
commercial broadcasters a choice of must-carry rights or retransmission-consent
rights and gave noncommercial educational broadcasters must-carry rights.  By
October 1993, cable operators were required to secure permission from
broadcasters that elected retransmission-consent rights before retransmitting
the broadcasters' signals.  Local and distant broadcasters can require cable
operators to make a payment as a condition to carriage of such broadcasters'
stations on a cable system.  Established superstations were not granted such
rights.  Commercial broadcasters make a new election between must carry
retransmission consent rights every three years.

     The 1992 Cable Act also imposed obligations to carry local broadcast
stations for such stations which chose a must-carry right, as distinguished from
the retransmission-consent right described above.  The 1992 Cable Act and the
rules adopted by the FCC generally provided for mandatory carriage by cable
systems of all local full-power commercial television broadcast signals
selecting must-carry, including the signals of stations carrying home-shopping
programming and, depending on a cable system's channel capacity, non-commercial
television broadcast signals.  On March 31, 1997, the United States Supreme
Court upheld the constitutionality of the must-carry provisions of the 1992
Cable Act.

     OWNERSHIP REGULATIONS.  The 1992 Cable Act required the FCC to:  (i)
promulgate rules and regulations establishing reasonable limits on the number of
cable subscribers which may be served by a single multiple system cable operator
or entities in which it has an attributable interest; (ii) prescribe rules and
regulations establishing reasonable limits on the number of channels on a 

                                       85
<PAGE>
 
cable system that will be allowed to carry programming in which the owner of
such cable system has an attributable interest; and (iii) consider the necessity
and appropriateness of imposing limitations on the degree to which multichannel
video programming distributors (including cable operators) may engage in the
creation or production of video programming. On September 23, 1993, the FCC
adopted regulations establishing a 30% limit on the number of homes nationwide
that a cable operator may reach through cable systems in which it holds an
attributable interest (attributable for these purposes is defined as a five
percent or greater ownership interest or the existence of any common directors),
with an increase to 35% if the additional cable systems are minority controlled.
However, the FCC stayed the effectiveness of its ownership limits pending the
appeal of a September 16, 1993, decision by the United States District Court for
the District of Columbia which, among other things, found unconstitutional the
provision of the 1992 Cable Act requiring the FCC to establish such ownership
limits. On appeal, however, the United States Court of Appeals for the District
of Columbia Circuit upheld the provision. As a result, DTG's ability to acquire
interests in additional cable systems may be affected.

     On September 23, 1993, the FCC also adopted regulations limiting carriage
by a cable operator of national programming services in which that operator
holds an attributable interest (using the same attribution standards as
discussed above) to 40% of the first 75 activated channels on each of the cable
operator's systems.  The rules provide for the use of two additional channels or
a 45% limit, whichever is greater, provided that the additional channels carry
minority controlled programming services.  The regulations also grandfather
existing carriage arrangements which exceed the channel limits, but require new
channel capacity to be devoted to unaffiliated programming services until the
system achieves compliance with the regulations.  Channels beyond the first 75
activated channels are not subject to such limitations, and the rules do not
apply to local or regional programming services.

     In the same rulemaking proceeding, the FCC concluded that additional
restrictions on the ability of multichannel distributors to engage in the
creation or production of video programming presently are unwarranted.

     Under the 1992 Cable Act and the FCC's regulations, a cable operator could
not hold a license for MMDS and DBS systems within the same geographic area in
which it provides cable service.  The Telecommunications Act would allow such
ownership if effective competition exists in that geographic area.

     The 1992 Cable Act contains numerous other provisions which, together with
the 1984 Cable Act, create a comprehensive regulatory framework.  Violation by a
cable operator of the statutory provisions or the rules and regulations of the
FCC can subject the operator to substantial monetary penalties and other
significant sanctions such as suspension of licenses and authorizations,
issuance of cease and desist orders and imposition of penalties.  Many of the
specific obligations imposed on the operation of cable television systems under
these laws and regulations are complex, burdensome and increase DTG's cost of
doing business.

     COPYRIGHT REGULATIONS.  The Copyright Revision Act of 1976 (the "Copyright
Act") provides cable television operators with a compulsory license for
retransmission of broadcast television programming without having to negotiate
with the stations or individual copyright owners for retransmission consent for
the programming.  The availability of the compulsory license is conditioned upon
the cable operators' compliance with applicable FCC regulations, certain
reporting requirements and payment of appropriate license fees, including
interest charges for late payments, pursuant to the schedule of fees established
by the Copyright Act and regulations issued thereunder.  The Copyright Act also
empowers the Copyright Office to periodically review and adjust copyright
royalty rates based on inflation and/or petitions for adjustments due to
modifications of FCC rules.  The FCC has recommended to Congress the abolition
of the compulsory license for cable television carriage of broadcast signals, a
proposal that has received substantial support from members of 

                                       86
<PAGE>
 
Congress. Any material change in the existing statutory copyright scheme could
significantly increase the costs of programming and be adverse to the business
interests of DTG.

     PRIVACY.  The 1984 Cable Act imposes a number of restrictions on the manner
in which cable system operators can collect and disclose data about individual
system customers.  The statute also requires that the system operator must
periodically provide all customers with written information about its policies
regarding the collection and handling of customer data, their privacy rights
under federal law and their enforcement rights.  In the event that a cable
operator is found to have violated the customer privacy provisions of the 1984
Cable Act, it could be required to pay damages, attorneys' fees and other costs.
Under the 1992 Cable Act, the privacy requirements are strengthened to require
that cable operators take such actions as are necessary to prevent unauthorized
access to personally identifiable information.

     STATE AND LOCAL REGULATION.  Because cable television systems use local
streets and rights-of-way, cable television systems are generally licensed or
franchised by local municipal or county governments and, in some cases, by
centralized state authorities with such franchises being given for fixed periods
of time subject to extension or renewal largely at the discretion of the issuing
authority.  The specific terms and conditions of such franchises vary
significantly depending on the locality, population, competitive services and a
number of other factors.  While this variance takes place among systems of
essentially the same size in the same state, franchises generally are
comprehensive in nature and impose requirements on the cable operator relating
to all aspects of cable service including franchise fees, technical
requirements, channel capacity, subscriber rates, consumer and service
standards, access channel and studio facilities, insurance and penalty
provisions.  Local franchise authorities generally must approve the sale or
transfer of cable systems to third parties.  The franchising process, like the
federal regulatory climate, can become highly politicized and no assurances can
be given that DTG's franchises will be extended or renewed or that other
problems will not be encountered at the local level.  In connection with the
franchise renewal process, LFAs commonly request the provision of enhanced cable
system technology as a condition of franchise renewal. The 1984 Cable Act grants
certain protective procedures in connection with renewal of cable franchises,
which procedures were further clarified by the renewal provisions of the 1992
Cable Act.

     PROPOSED CHANGES IN REGULATION.  The regulation of cable television systems
at the federal, state and local levels is subject to the political process and
has been in constant flux over the past decade.  Material changes in the law and
regulatory requirements must be anticipated and there can be no assurance that
DTG's business will not be affected adversely by future legislation, new
regulation or deregulation.  Legislative, administrative and/or judicial action
may change all or portions of the foregoing statements relating to competition
and regulation.

     CABLE PROVISION OF INTERNET SERVICES.  Transmitting indecent material via
the Internet is made criminal by the Telecommunications Act.  However, on-line
access providers are exempted from criminal liability for simply providing
interconnection service; they are also granted an affirmative defense from
criminal or other action where in "good faith" they restrict access to indecent
materials.  The Telecommunications Act further exempts on-line access providers
from civil liability for actions taken in good faith to restrict access to
obscene, excessively violent or otherwise objectionable material.  On June 26,
1997, the United States Supreme Court held unconstitutional the provisions of
the Telecommunications Act criminalizing indecent on-line transmissions.

     REGULATION OF INTERNET SERVICES.  Internet-related services are not
currently subject to direct regulation by the FCC or any other United States
agency, other than regulation applicable to businesses generally.  The FCC
recently rejected requests that it regulate certain voice transmissions over the
Internet as telecommunications services.  Changes in the regulatory environment
relating to the telecommunications or Internet-related services industry could
have an adverse effect on DTG's Internet-related services business.  The
Telecommunications Act may permit 

                                       87
<PAGE>
 
telecommunications companies, RBOCs or others to increase the scope or reduce
the cost of their Internet access services. In its recent access charge reform
proceeding, the FCC concluded that incumbent LECs may not assess interstate
access charges on information service providers but stated that it planned to
address issues relating to information service providers' use of the public
switched network as part of a broader set of issues under review in a related
proceeding. Given the present unsettled nature of the regulation of Internet
services, DTG cannot predict the effect that the Telecommunications Act or any
future legislation, regulation or regulatory changes may have on its business.

     In addition to the regulatory uncertainties, the law relating to the
liability of on-line services providers and Internet access providers for
information carried on, disseminated through or hosted on their systems is
currently unsettled.  Several private lawsuits seeking to impose such liability
are currently pending.  In one action brought against an Internet access
provider, Religious Technology Center v. Netcom On-Line Communication Services,
Inc., the United States District Court for the Northern District of California
ruled in a preliminary phase that under certain circumstances Internet access
providers could be held liable for copyright infringement.  The case has been
settled by the parties.

     The Telecommunications Act prohibits and imposes criminal penalties and
civil liability for using an interactive computer service for transmitting
certain types of information and content, such as indecent or obscene
communications.  On June 12, 1996, however, a panel of three federal judges
granted a preliminary injunction barring enforcement of this portion of the
Telecommunications Act to the extent that enforcement is based upon allegations
other than obscenity or child pornography as an impermissible restriction on the
First Amendment's right of free speech.  That decision was appealed to the
United States Supreme Court, which held the provisions unconstitutional.  In
addition, Congress, in consultation with the United States Patent and Trademark
Office and the Clinton Administration's National Information Infrastructure Task
Force, is currently considering legislation to address the liability of on-line
service providers and Internet access providers, and numerous states have
adopted or are currently considering similar types of legislation.  The
imposition upon Internet access providers or Web hosting sites of potential
liability for materials carried on or disseminated through their systems could
require DTG to implement measures to reduce its exposure to such liability,
which may require the expenditure of substantial resources or the
discontinuation of certain product or service offerings. DTG believes that it is
currently unsettled whether the Telecommunications Act prohibits and imposes
liability for any services provided by I-way should the content or information
transmitted be subject to the Telecommunications Act.

     The law relating to the liability of on-line service providers and Internet
access providers in relation to information carried, disseminated or hosted also
is being discussed by the World Intellectual Property Organization in the
context of ongoing consideration of updating existing, and adopting new,
international copyright treaties.  Similar developments are ongoing in the
United Kingdom and other jurisdictions.  The scope of authority of various
regulatory bodies in relation to on-line services is currently uncertain.

     The Office of Telecommunications in the United Kingdom recently has
published a consultative document setting out a number of issues for discussion,
including the roles of traditional telecommunications and broadcasting
regulators with respect to on-line services.  The Securities Investment Board in
the United Kingdom is investigating the status of on-line services and the
transmission of investment information over networks controlled by access
providers.  Such transmissions may make an access provider liable for any
violation of securities and other financial services legislation and
regulations.  Decisions regarding regulation, enforcement, content liability and
the availability of Internet access in other countries may significantly affect
the ability to offer certain services worldwide and the development and
profitability of companies offering Internet and on-line services in the future.
For example, it has been reported that CompuServe recently removed certain
content from its services worldwide in reaction to law enforcement activities in
Germany, and 

                                       88
<PAGE>
 
it has been reported that an Internet access provider in Germany has been
advised by prosecutors that it may have liability for disseminating neo-Nazi
writings by providing access to the Internet where these materials are
available.

     The increased attention focused upon liability issues as a result of these
lawsuits, legislation and legislative proposals could affect the growth of
Internet use.  Any costs incurred as a result of liability or asserted liability
for information carried on or disseminated through its systems could have a
material adverse effect on the business, financial condition and results of
operations of DTG.

     SUMMARY ONLY.  The foregoing is only a summary of some of the present and
proposed federal, state and local regulations and legislation relating to DTG's
businesses.  Other existing federal regulations, copyright licensing and, in
many jurisdictions, state and local regulatory requirements, currently are the
subject of a variety of judicial proceedings, legislative hearings and
administrative and legislative proposals which could change, in varying degrees,
the manner in which DTG operates.  Neither the outcome of these proceedings nor
their impact upon DTG can be predicted at this time.


EMPLOYEES

     As of September 30, 1998, DTG employed 166 employees, 147 of whom were
full-time employees and none of whom was subject to any collective bargaining
agreement.


ENVIRONMENTAL AND OTHER MATTERS

     Except for site-specific issues, environmental issues tend to impact
members of the telecommunications industry in consistent ways.  The United
States Environmental Protection Agency ("EPA") and other agencies regulate a
number of chemicals and substances that may be present in facilities used in the
provision of telecommunications services.  These include preservatives which may
be present in certain wood poles, asbestos which may be present in certain
underground duct systems and lead which may be present in certain cable
sheathing.  Components of DTG's network may include one or more of these
chemicals or substances.  DTG believes that in their present uses, none of such
facilities of DTG poses any significant environmental or health risk that
derives from EPA regulated substances.  If EPA regulation of any such substance
is increased, or if any facilities are disturbed or modified in such a way as to
require removal of the substance(s), special handling, storage and disposal may
be required for any such facilities removed from use.

RECENT DEVELOPMENTS

     In July 1998, DTG and its wholly owned subsidiary DWS acquired by merger
Vantek.  Vantek is a leading mobile radio operator and operates one of the
largest paging businesses in South Dakota.  Under the terms of the merger
agreement, Vantek was merged with and into DWS, which is now a wholly owned
subsidiary of DTG, operating both DWS' current PCS business and Vantek's
existing mobile radio and paging business. In addition, on November 1, 1998 DTG,
through DWS, acquired substantially all of the assets of Hurley Communications,
a regional specialized mobile radio company and a cellular telephone agent
serving an area complementary to that served by DWS.

PROPERTIES

     The tangible assets of DTG include a substantial investment in
telecommunications and cable equipment.  The net book value of DTG's fixed
assets was $26.3 million as of September 30, 1998.  No single property
represents 10% or more of DTG's total assets.

     The principal properties of DTG do not lend themselves to simple
description by character and location.  DTG's investment in property, plant and
equipment consisted of the following at December 31, 1996 and 1997, and
September 30, 1998:

     Telecommunications plants consists of switching equipment, transmission
equipment and related facilities, aerial cable, underground cable, conduit and
wiring.  Cable systems consist of head-end, distribution and subscriber
equipment.  Other equipment consists of public telephone instruments and
telephone equipment (including PBXs) used or leased by DTG in its operations,
poles, furniture, office equipment, vehicles and other work equipment.  Land and
buildings consist of land owned in fee and improvements thereto, principally
central office buildings.  Other property consists primarily of plant under
construction, capital leases and leasehold improvements.

     DTG's rights-of-way for its telecommunications and cable transmission
systems are typically held under leases, easements, licenses or governmental
permits.  All other major equipment and physical facilities are owned in fee and
are operated, constructed and maintained pursuant to rights-of-way, easements,
permits, licenses or consents on or across properties owned by others.

     DTG believes that standard practices prevailing in the telephone industry
are followed by DTG's telephone operating subsidiaries in the construction and
maintenance of plant and facilities and that all properties presently being used
for operations of DTG are suitable, well maintained and adequately equipped for
the purposes for which they are used.  Substantially all of DTG's properties are
subject to mortgage liens held by the Rural Telephone Finance Cooperative (the
"RTFC").

LEGAL PROCEEDINGS

     DTG and its subsidiaries are parties, as plaintiff or defendant, to a
number of legal proceedings.  Except as described below, all of these
proceedings are considered to be ordinary routine litigation incidental to their
businesses and none is considered to be a material pending legal proceeding.

     The incumbent cable provider in Marshall, Minnesota, Bresnan Communications
("Bresnan"), filed an appeal with the Minnesota Court of Appeals (File No. C8-
98-1139) on June 26, 1998, of the grant of a competitive franchise by the City
of Marshall to DTG.  The parties to the appeal are Bresnan, the City of Marshall
and DTG.  The appeal seeks to have the appellate court reverse the decision
granting the franchise.

     In addition, on June 26, 1998, Bresnan filed an action in state court
(Fifth Judicial Circuit) directly against the City of Marshall alleging a
failure to provide certain requested information and a violation of the open
meeting laws by the Marshall Municipal Utilities Commission and the City in the
consideration of the grant of the franchise to DTG.  Bresnan alleges that this
conduct has so tainted the granting of the franchise that the court should find
the franchise to be void.  DTG is not a party to this lawsuit but will continue
to monitor its progress.  Based on information presently available, DTG believes
that neither legal action is meritorious.  Because DTG is a party to the appeal,
it will file briefs and orally argue its position before the appellate court.
However, in light of the possible negative outcomes to either of these actions,
DTG has suspended further work in the Marshall area.  Construction efforts and
funds intended for Marshall equipment have been shifted to other areas where DTG
has been awarded franchises.  If Bresnan is successful in either action, the
financial impact on DTG for work already completed is not expected to be
material and is not expected to have a materially adverse effect on future
periods.

     In addition, on October 1, 1998, Bresnan filed an action in the District
Court of the State of Minnesota (Fifth District) against DTG alleging, among
other things, defamation and disparagement of Bresnan's business.  The action is
based on the publication of a letter by DTG in the Marshall Independent
                                                   --------------------
newspaper.  Bresnan seeks damages in an amount in excess of $50,000, together
with interest and attorney's fees.  DTG believes it has meritorious defenses and
plans to vigorously defend this action.

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

     The following discussion is provided by DTG management as its analysis of
DTG's financial condition and results of operations.  This analysis should be
read in conjunction with the separate consolidated financial statements of DTG
and its subsidiaries as of December 31, 1997 and 1996 and the notes thereto (the
"DTG Annual Financial Statements") and the unaudited consolidated financial
statements of DTG and its subsidiaries as of September 30, 1998 and the notes
thereto (the "DTG Interim Financial Statements") included in this Prospectus and
Proxy Statement.

OVERVIEW

     DTG is a diversified communications services company specializing in the
design, construction and operation of broadband hybrid fiber optic
communications systems for small communities in South Dakota and the surrounding
states.  DTG provides a full range of bundled products and services to its
customers, including switched local dial tone and enhanced services, network
access services, long distance telephone services, operator assisted calling
services, telecommunications equipment sale and leasing services, cable
television services, computer equipment sales, mobile radio, paging, Internet
access and related services and computer and computer networking products and
services, using both wireline and wireless technologies.

     In 1996 DTG began a major reorganization and expansion program.  This
program included the conversion of DTG from a stock cooperative into a publicly
held Delaware corporation, the redesign and rebuilding of DTG's switching center
and fiber backbone network, which was completed in 1997, and the expansion of
DTG's operations through selected acquisitions.  During 1996, DTG purchased the
assets of 19 cable television systems.  In December 1996, DTG, through a wholly
owned subsidiary, merged with TCIC, a South Dakota-based provider of long
distance and operator services.  Also in December 1996, in a similar
transaction, DTG merged with I-way, one of South Dakota's largest Internet
service providers.  In December 1997, DTG merged with DataNet, a leading
regional LAN/WAN computer integrator located in Sioux Falls, South Dakota.
These companies continue to operate as wholly owned subsidiaries of DTG under
the names DTG Communications, Inc., DTG Internet, Inc. and DTG DataNet, Inc.,
respectively.

     In July 1998, DTG, through a wholly owned subsidiary, merged with Vantek, a
regional specialized mobile radio and paging company in southeastern South
Dakota. Vantek continues to operate as a wholly owned subsidiary of DTG under
the name DWS. On November 1, 1998 DTG, through DWS, acquired substantially all
of the assets of Hurley Communications, a regional specialized mobile radio
company and a cellular telephone agent serving an area complementary to that
served by DWS.

     In conjunction with the Merger Agreement, DTG and McLeodUSA entered into a
20-year dark fiber lease agreement with an aggregate value of $5 million paid by
McLeodUSA in advance on October 28, 1998. Revenues under this agreement will be
reported on a deferred basis, resulting in additional revenues in 1998 of
approximately $42,000 and approximately $250,000 per year for the remainder of
the lease term.

     DTG's reorganization and expansion plans have had, and will continue to
have, significant impacts on DTG's financial condition and results of
operations. As part of its network-rebuilding project, in 1995 DTG reassessed
the remaining useful life of its old facilities. In 1996 and 1997, DTG incurred
approximately $5.8 million and $13.6 million in new capital expenditures,
respectively. During the first nine months of 1998, DTG incurred an additional
$3.9 million in capital expenditures and purchased $703,000 of additional
materials for its 1998 developments. DTG anticipates spending substantial
additional funds for its continuing development programs. These

                                       93
<PAGE>
 
expenditures have been, and future expenditures are anticipated to be, financed
through substantial increases in DTG's long-term debt. These changes are
expected to combine to result in substantially higher depreciation and interest
expenses with corresponding reductions in DTG's net income. In addition, to
implement its growth plans, DTG completed the acquisitions described above and
increased its employee base from 34 employees at December 31, 1995 to 185
employees at September 30, 1998, resulting in additional increases in
amortization expense and employee-related operating expenses. While DTG
anticipates that its revenue base would continue to grow as it completes its new
facilities and markets new services, the resultant higher expense levels from a
combination of higher depreciation, amortization and interest expense, as well
as additional employee expenses, would likely cause DTG to recognize and report
net after-tax losses.

FINANCIAL CONDITION, LIQUIDITY AND CAPITAL RESOURCES

     The implementation of DTG's reorganization plans has had a significant
impact on DTG's balance sheet and financial condition.  The following discussion
reviews the material changes in DTG's balance sheet accounts.

     SEPTEMBER 30, 1998 COMPARED TO DECEMBER 31, 1997

     Cash and Cash Equivalents and Temporary Cash Investments decreased from
$4,598,000 at December 31, 1997, to $1,805,000 at September 30, 1998, a decrease
of $2,793,000.  The decrease was used for capital expenditures, investment in
acquisitions and to fund operating expenses.

     Net Accounts Receivable decreased from $4,216,000 at December 31, 1997, to
$3,749,000 at September 30, 1998, a decrease of $467,000.  This decrease was
primarily due to the payments of additional funds due to DTG from the National
Exchange Carriers Association for final adjustments to DTG's access revenue
requirements from its 1996 and 1997 telephone operation cost studies.

     Materials and Supplies inventories increased from $1,109,000 at December
31, 1997 to $1,884,000 at September 30, 1998, an increase of $775,000.  Of the
increase, $72,000 was a non-cash transaction related to the acquisition of
Vantek. The balance of this increase represents additional materials on hand to
be used in DTG's 1998 and 1999 development projects.

     Prepaid Expenses increased from $276,000 at December 31, 1997 to $427,000
at September 30, 1998, an increase of $151,000.  This increase was due to an
increase in prepaid insurance.

     Other Investments decreased from $2,038,000 at December 31, 1997 to
$1,524,000 at September 30, 1998, a decrease of $514,000.  This decrease was
primarily due to a sale of a treasury bill by DTG during the first quarter of
1998.

     Deferred Charges increased from $653,000 at December 31, 1997 to $1,507,000
at September 30, 1998, an increase of  $854,000, which was primarily related to
software purchases and development for DTG's new billing system and construction
project deposits.

     Current Liabilities increased from $6,922,000 at December 31, 1997 to
$7,407,000, at September 30, 1998, a net increase of $485,000. The increase is
primarily related to an increase in accrued liabilities for DTG contributions to
DTG's Employee Stock Ownership Plan, which was adopted in December 1997.

     Long-Term Debt increased from $29,200,000 at December 31, 1997 to
$30,793,000, at September 30, 1998, an increase of $1,593,000. This increase is
the result of $2,400,000 in advances made under a $6,000,000 revolving credit
line with the RTFC, offset by payments on existing Long-Term Debt.  The advances
were used to fund DTG's 1998 construction projects.   See Notes 2 and 3 to the
DTG Interim Financial Statements.

                                       94
<PAGE>
 
     Total Stockholders' Equity decreased from $7,804,000 at December 31, 1997
to $5,310,000 at September 30, 1998, a decrease of approximately $2,494,000.
This decrease was caused by DTG's operating losses of $3,828,000 during the
first nine months of 1998 offset by additional equity raised by DTG from the
exercise of outstanding warrants and the sale of stock to DTG's existing
stockholders.  See Note 6 to the DTG Interim Financial Statements.

</TABLE>

     Cash and Temporary Cash Investments increased from $2,870,400 at December
31, 1996, to $4,597,900 at December 31, 1997, an increase of $1,727,500.
Approximately $200,000 of this increase was attributable to DataNet, which was
acquired by DTG in December 1997.  The balance represents long-term debt
borrowings by DTG in late December 1997 in anticipation of the repayment of
DTG's $1,500,000 short-term revolving loan from the RTFC in early January 1998.
See Note 4 to the DTG Annual Financial Statements.

     Net Accounts Receivable increased from $1,784,900 at December 31, 1996, to
$4,216,000 at December 31, 1997, an increase of $2,431,100.  Of this increase,
$1,779,600 was attributable to net receivables from DataNet, which was acquired
in December 1997.  The balance of this increase is primarily related to
additional funds due to DTG from final adjustments to its access revenue
requirements from its 1996 and 1997 telephone operation cost studies.  See Note
1(M) to the DTG Annual Financial Statements.

     Materials and Supplies inventories increased from $694,100 at December 31,
1996, to $1,109,200 at December 31, 1997, an increase of $415,100.  Of this
increase, $187,000 was related to the inventories of goods held for resale in
DTG's DataNet operation.  The balance represents materials on hand to be used in
DTG's planned development projects.

     Excess of Cost Over Net Assets Acquired increased from $1,831,000 at
December 31, 1996, to $4,869,100 at December 31, 1997, an increase of
$3,038,100.  This increase is due to DTG's acquisition of DataNet in December
1997, which was accounted for using the purchase method.  See Note 13 to the DTG
Annual Financial Statements.

     Other Investments increased from $625,700 at December 31, 1996, to
$2,037,600 at December 31, 1997, an increase of $1,411,900.  This increase was
primarily due to the purchase by DTG of RTFC subordinated capital certificates
in connection with the long-term financing agreement reached with the RTFC in
July 1997.  These certificates bear no interest and will be refunded to DTG upon
retirement of the associated debt.  See the discussion of the RTFC financing
agreement, below, and Note 6 to the DTG Annual Financial Statements.  DTG
anticipates making further investments in RTFC capital certificates as it
continues to borrow additional long-term funds from the RTFC.

     Net fixed assets increased from $14,441,100 at December 31, 1996, to
$25,408,300 at December 31, 1997, a net increase of $10,967,200.  This increase
primarily represents additional telecommunications plant assets constructed by
DTG in 1997.  See Note 3 to the DTG Annual Financial Statements.  DTG currently
plans to make substantial additional investments in new telecommunications
facilities and accordingly expects net fixed assets to significantly increase in
future years as these facilities are constructed.

     Current Liabilities increased from $1,594,800 at December 31, 1996, to
$6,921,800 at December 31, 1997, an increase of $5,327,000.  Approximately
$1,500,000 of this increase was attributable to normal current liabilities
associated with DataNet.  These liabilities included approximately $569,300 in
floor plan financing arrangements.  See Note 5 to the DTG Annual Financial
Statements.  An additional $1,500,000 of the increase represents amounts due
under DTG's short-term revolving loan arrangement with the RTFC, which was
repaid in full in early January 1998.  See Note 4 to the DTG Annual Financial
Statements.  The current portion of DTG's long-term debt increased $692,300 due
to the overall increase in DTG's total long-term debt.  The remaining increase
related primarily to current amounts due suppliers and contractors in connection
with DTG's 1997 development projects.

     Long-Term Debt increased from $15,338,400 at December 31, 1996, to
$29,200,500 at December 31, 1997.  At December 31, 1997, this debt consisted of
approximately $29,600,000 under a series of loans from the RTFC and $1,000,000
in long-term financing from Home Federal Savings Bank associated with the
guarantee by DTG of long-term debt incurred by DTG's Employee Stock Ownership
Plan to fund the acquisition of DTG Common Stock in December 1997, net of
$1,390,000 in associated current maturities.  See Note 6 to the DTG Annual
Financial Statements.   On June 24, 1997, DTG entered into a long-term loan
arrangement with the RTFC in the aggregate amount of $28,421,000.  Of this
amount, $13,092,089 was used to refinance the then outstanding long-term debt
from the Rural Utilities Service on July 15, 1997.  The remaining amounts are
allocated to refinance the $1,000,000 in debt assumed by DTG in the TCIC and I-
way acquisitions and to cover DTG's 1997 capital expenditures program.
Substantially all of DTG's 1997 capital expenditures were financed by the RTFC.

     Total Stockholders' Equity increased from $6,412,200 at December 31, 1996,
to $7,804,100 at December 31, 1997, an increase of approximately $1,400,000.
This increase was primarily caused by the issuance of stock in connection with
the DataNet acquisition, reduced by DTG's 1997 operating loss.  The presentation
of the Stockholders' Equity account structure changed substantially during 1997
due to the conversion of DTG from a South Dakota stock cooperative into a
Delaware corporation in July 1997 in the Conversion-Merger.  The primary change
was the reclassification of the capital accounts from preferred stock and
cooperative capital credits into common stock.  The Conversion-Merger, by
itself, did not change overall total equity.  The Conversion-Merger process is
discussed in more detail above and in Notes 2, 7 and 15 to the DTG Annual
Financial Statements.

LIQUIDITY AND CAPITAL RESOURCES

     DTG believes that it has adequate internal resources available to finance
its current operating requirements.  Net Cash Used In Operations was $284,000 in
the first nine months of 1998.  See the Consolidated Statement of Cash Flows
included in the DTG Interim Financial Statements. As discussed above, DTG
entered into a 20-year dark fiber lease agreement with McLeodUSA in October 1998
under which McLeodUSA made a one-time payment of $5 million.  In addition, DTG
maintains two lines of credit with the RTFC, a $1.5 million revolving credit
line which was fully drawn at September 30, 1998 and a $6 million project
development line of credit with the RTFC, $3.6 million of which was available as
of September 30, 1998.  Finally, DTG uses a combination of the floor plan
financing arrangements and a $2,000,000 working capital line of credit to fund
inventory holding costs in its DataNet operation.  See Notes 2 and 3 to the DTG
Interim Financial Statements.

     DTG's 1999 expansion plans will require it to substantially expand its
employee base beginning in November 1998, resulting in additional employee
expenses which will likely cause DTG to experience negative monthly operating
cash flows until its new development projects are completed and new subscribers
are added in late 1999 and in the year 2000.  In addition, DTG currently
anticipates investing between $50 and $55 million in new capital expenditures in
1999 in connection with its new development projects.  DTG currently plans to
fund these requirements through a combination of additional equity and long-term
project debt.

     DTG's primary long-term lender is the RTFC, which provided the funds for
DTG's 1997 and 1998 construction projects.  On July 17, 1998, the RTFC agreed to
additional long-term financing in the amount of $35,263,128. This financing is
contingent on DTG raising an additional $20 million in equity.  Under the terms
of the Merger Agreement with McLeodUSA, McLeodUSA is required to make a capital
contribution to DTG of $20 million immediately following the completion of the
Merger. DTG currently plans to use this equity to support the additional long-
term debt financing from the RTFC, and to use the combination of these funds to
finance its operations and capital expenditure program in 1999. While the Merger
with McLeodUSA is expected to be completed within three to six months, it is
subject to a number of conditions outside of DTG's control including, but not
limited to, approval by DTG's stockholders, FCC license transfers and various
other regulatory approvals.  There can be no assurance that the Merger will be
completed.  If the Merger is not completed, DTG would be unable to finance its
expansion plans and would likely stop its ongoing development activities and
substantially reduce the size of its operations. In such an event, management
believes that DTG's operations would return to positive operating cash flow
within three months.

     As part of DTG's expansion program, DTG routinely enters into cable
television franchise agreements with new communities.  Some of these agreements
require DTG to post performance and development bonds.  As of September 30,
1998, DTG has secured performance and payment bonds and irrevocable letters of
credit totaling $832,500 to various cities that have granted franchise
agreements to DTG. Of this amount, $650,000 is secured by promissory notes
between DTG and one of its lenders. In addition, DTG has had issued an
additional $25,000 in performance bonds since the end of the third quarter. See
Note 9 to the DTG Interim Financial Statements.  Prior to the start of
construction in the various markets that have granted franchise agreements, DTG
will be required to post an additional $1.6 million in construction bonds. As
new franchise agreements are granted there will be corresponding increases in
the bonding requirements of DTG.  While DTG has not experienced any difficulty
in posting these bonds in the past, absent the completion of the Merger with
McLeodUSA or another transaction providing additional equity to DTG, there is no
assurance that it will be able to continue to provide the financial resources to
post additional bonds in the future.

RESULTS OF OPERATIONS

     DTG's reorganization plans have also significantly changed its results of
operations, primarily due to the additional entities acquired by DTG in the
mergers described above.  As a result, the comparison of the financial results
of DTG's present operations to its past operations should be carefully analyzed.
The following discussion summarizes DTG's results of operations.

     Nine Months ended September 30, 1998 and 1997

     Total Operating Revenues increased from $8,441,000 during the first nine
months of 1997 to $24,222,000 in the same period during 1998, an increase of
$15,781,000, or approximately 187%.  Of this increase, $13,440,000 reflects the
addition of revenues from DTG's DataNet and DWS operations acquired in December
1997 and July 1998.  Of this increase, $1,301,000 represents additional access
revenues, discussed in more detail below. The balance reflects other internal
growth in DTG's operations.

     Plant Operations expense increased from $2,673,000 during the first nine
months of 1997 to $4,449,000 during the same period of 1998, an increase of
$1,776,000, or approximately 66%.  Approximately $62,000 of this increase was
due to the additional costs and expenses associated with the operation of the
DataNet and DWS operations.  Approximately $1,398,000 is related to increased
access costs from DTG's long distance and Internet operations.  The remaining
increase is related primarily to the start-up and operational costs associated
with DTG's CLEC operations in its new markets.

     Cost of Goods Sold, a new category of operating expense, was $10,377,000 in
the first nine months of 1998, reflecting expenses associated with DTG's DataNet
and DWS operations.

     Depreciation and Amortization expense increased from $2,380,000 in the
first nine months of 1997 to $3,313,000 in the same period of 1998, an increase
of $933,000 or approximately 39%.  Approximately $230,000 of this increase was
due to the amortization of the excess of cost over net assets acquired in the
acquisition of DataNet and DWS, as well as the depreciation expense of assets
used in these operations.  The balance of this increase was due primarily to the
depreciation of additional assets placed in service by DTG during 1997 and in
the first nine months of 1998 as part of its network expansion program.

     Customer operating expenses increased from $828,000 in the first nine
months of 1997 to $2,370,000 in the same period of 1998, an increase of
$1,542,000, or approximately 186%.  Of this increase, $901,000 related to the
customer service expenses associated with the DataNet and DWS operations. The
remaining increase is primarily due to increased costs in DTG's CLEC operations
in its new markets.

     Other costs and expenses, including General and Administrative and Other
Operating Expenses, increased from $3,837,000 during the first nine months of
1997 to $6,047,000 in the same period of 1998, an increase of $2,210,000, or
approximately 58%.  Of these expenses, $90,951 in 1997 was due to the inclusion
of one-time, nonrecurring charges associated with the Conversion-Merger of DTG
into a publicly traded business corporation in 1997.  Of these expenses, $57,000
in 1998 was due to the inclusion of one-time, nonrecurring charges associated
with the registration and sale of stock to DTG's stockholders during the first
quarter.  See Note 6 to the DTG Interim Financial Statements.  Of the remaining
$2,169,000 increase in other costs and expenses, approximately $796,000 was due
to the additional costs and expenses from the operations of DataNet and DWS. The
remaining increase is primarily due to increased costs in DTG's CLEC operations
in its new markets.

     Interest Expense increased from $791,000 for the first nine months of 1997
to $1,653,000 during the same period in 1998, an increase of $862,000, or
approximately 109%. This increase is

                                       98
<PAGE>
 
primarily due to the increase in long-term debt incurred by DTG to fund its 1997
and 1998 capital expenditures.

     Basic loss per share for the first nine months of 1998, based on 2,692,321
outstanding shares, was $1.42. This compares with a loss of $1.56 per share for
the first nine months of 1997 on 985,216 average outstanding shares.   See Note
8 to the DTG Interim Financial Statements.

</TABLE>

     In 1997, revenues increased substantially to $13,729,000, up from
$8,101,300 in 1996, an increase of  $5,627,700 or 69.5%.  Of this increase,
$1,481,000, $1,021,000, and $1,788,100 was attributable to revenues from DTG's
TCIC, I-way and DataNet operations, respectively.  The balance of the increase
represents primarily revenues from access rate increases put into effect by DTG
during 1996.

     Depreciation and Amortization expense increased from $2,434,400 in 1996 to
$3,448,100 in 1997, an increase of approximately $1,000,000 or 41%.
Approximately $133,300 of this increase is attributable to the amortization of
the excess of cost over the net assets acquired in the merger transactions with
TCIC and I-way in December 1996 and with DataNet in December 1997.  The balance
represents additional depreciation for assets placed in service during 1997.

     Other Costs and Expenses increased to $12,039,600 in 1997, up from
$5,589,100 in 1996, an increase of $6,450,500 or 115%.  Of this increase,
$1,214,100, $2,170,100, and $1,732,700 represent additional costs and expenses
associated with the I-way, TCIC and DataNet operations, respectively.  An
additional $611,342 of this increase represents one-time, nonrecurring charges
associated with the Conversion-Merger in July 1997.  These reorganization
expenses do not arise from and are not representative of DTG's ongoing business.
See Note 2 to the DTG Annual Financial Statements included in this Prospectus
and Proxy Statement.  The balance of the increase is primarily due to increased
employee costs in DTG's telephone and cable operations.

     Other Income and Expense consists primarily of interest and dividend income
and interest expense.  Interest expense in 1997 was $1,122,807 (total interest
expense of 1,294,607 net of $171,800 that was capitalized as construction period
interest related to DTG's 1997 developments) compared to $723,778 in 1996, an
increase of $399,029 or 55%.  The increase in interest expense was caused
primarily by increased long-term borrowings used by DTG to finance its 1997
construction projects.

     On a pro forma basis, assuming that all shares issuable in the
reorganization were outstanding for all of 1997, and assuming all capital stock
and capital credits were converted into shares of DTG Common Stock at a rate of
$2.50 per share at the beginning of 1996, loss per share would have been $1.19
for 1997 and $.09 for 1996.  Also on a pro forma basis, assuming that only those
shares that were actually issued and outstanding as of March 16, 1998, had been
outstanding for all of 1997, loss per share for 1997 would have been $1.30.

     RESULTS OF BUSINESS SEGMENT OPERATIONS FOR THE YEAR ENDED DECEMBER 31, 1997
AND THE YEAR ENDED DECEMBER 31, 1996

     As of December 31, 1997, DTG operated with three major business segments:
telephone operations, which includes all operations other than cable television
and computer networking operations; cable television operations; and the
computer networking services acquired by DTG in the DataNet transaction in
December 1997.

     The following sections discuss the operating results for these three
segments in 1997 and 1996.

     Access revenues are received by LECs for intrastate and interstate exchange
services provided to IXCs which enable IXCs to provide long distance service to
end users in the local exchange network.  Access revenues are determined, in the
case of interstate calls, according to rules issued by the FCC and administered
by the National Exchange Carriers Association ("NECA") and, in the case of
intrastate calls, by state regulatory agencies.  See "Access Revenues," on page
__.  A relatively small portion of DTG's access revenues are derived from
subscriber line fees determined by the FCC and billed directly to end users for
access to long distance carriers.  The balance of DTG's interstate access
revenues are received from NECA, which collects payments from IXCs and
distributes settlement payments to LECs based on a number of factors, including
the cost of providing service and the amount of time the local network is
utilized to provide long distance services.  A variety of factors, including
increased subscriber counts, cultural and technological changes and rate
reductions by IXCs, have resulted in a consistent pattern of increasing use of
the nation's telephone network since 1984.  This growth has produced higher
revenues for NECA and increased settlements for its participating LECs.  Access
revenues increased from $3,267,000 in 1996 to $4,176,700 in 1997, an increase of
$909,700 or 27.8%.  DTG reassesses its access rates and underlying cost studies
annually and adjusts its tariff rate filings and participation in NECA and
Universal Service Fund revenue pools accordingly.  In late 1996, DTG received
approval from the South Dakota Public Utilities Commission to increase its
intrastate access rates approximately 20%, which increase, combined with
increased settlements from the NECA pool, primarily accounts for the overall
increase in access revenue in 1997.

     Local service revenues are earned by providing customers with local service
to connecting points within the local exchange boundaries and, in certain cases,
to nearby local exchanges under extended area service ("EAS") plans that
eliminate long distance charges to the neighboring exchanges.  Local service
revenues for 1997 were $1,221,800 compared to $1,058,700 in 1996, an increase of
15%.  This increase was due primarily to a local service rate increase approved
by the DTG Board in December 1995 and implemented in February and July 1996.
There are no local rate requests currently pending for DTG nor does DTG
currently anticipate any local rate increases.

DTG's local service rates are not currently regulated by the FCC or the South
Dakota Public Utilities Commission, although certain regulatory policies of both
agencies indirectly impact local rate levels.

     Long distance toll revenues rose from $1,996,300 in 1996 to $3,478,700 in
1997, an increase of $1,482,400 or 74%.  This increase was primarily due to long
distance revenues from the TCIC long distance reselling operation acquired by
DTG in December 1996.

     Internet service revenue rose from $72,447 in 1996 to $1,021,344 in 1997,
an increase of $951,897 or 1,314% due to the inclusion of revenues from the I-
way Internet operations acquired in December 1996 and internal growth in
revenues from DTG's Internet operations.

     Other revenues decreased from $357,800 in 1996 to $149,800 in 1997, a
decrease of $208,000 or 58%.  Most of this decrease is due to the transfer of
DTG's unregulated customer premises equipment business from its Telephone
Operations segment to its Cable Television Operations segment in January 1997.

     Depreciation and amortization expenses rose from $2,011,000 in 1996 to
$2,728,000 in 1997, an increase of $717,000 or 36% as a result of DTG's
additional capital expenditures for the year and the amortization of costs
associated with its acquisitions of TCIC and I-way.  See Note 13 to the DTG
Annual Financial Statements.

     Other costs and expenses were $8,703,600 in 1997 compared to $4,287,100 in
1996, an increase of $4,416,500 or 103%.  Of this increase, $1,214,100 and
$2,170,100 represent additional costs and expenses associated with the Internet
and long distance operations acquired in December 1996.  An additional $611,342
of this increase represents one-time, nonrecurring charges associated with the
Conversion-Merger in July 1997.  These reorganization expenses do not arise from
and are not representative of DTG's ongoing business.  See Note 2 to the DTG
Annual Financial Statements.  The balance of the increase is primarily due to
increased employee expense.

     DTG's cable service revenues increased from $1,300,500 in 1996 to
$1,517,000 in 1997, an increase of $216,500 or 17%.  This increase primarily
reflects additional revenues for the entire year of 1997 from the 19 cable

ACCESS REVENUES

     Access revenues are the result of tariffs developed, filed and imposed by
local exchange companies for allowing long distance carriers (generally referred
to as IXCs) to access their end user customers in the local exchange network.
For small ILECs like DTG who are members of the NECA, access revenues are
determined, in the case of interstate calls, according to rules issued by the
FCC and administered by NECA and, in the case of intrastate calls, by state
regulatory agencies.  The entire access charge environment for small ILECs is
subject to a complex and changing set of state and federal regulations, with
some of the revenues directly billed to end users in the form of subscriber line
fees and federal/state access charges, and some of the revenues coming directly
from NECA.  Current rules also result in different calculations of revenue
requirements depending on (i) company size; (ii) whether a company is a  RBOC or
non-RBOC company; and (iii) whether a company is a rural or non-rural company.

     For NECA members like DTG, NECA acts as a pooling mechanism and imposes a
uniform tariff on IXC's for NECA-member companies.  NECA collects payments from
IXCs and distributes settlement payments to its members based on a number of
factors, including the allocated cost of providing service.  A variety of
factors, including increased subscriber counts, cultural and technological
changes and rate reductions by IXCs, have resulted in a consistent pattern of
increasing use of the nation's telephone network since 1984.  This growth has
produced higher revenues for NECA and increased settlements for its
participating members, including the ILEC division of DTG.  These increases,
notwithstanding the increase in DTG's ILEC operating expenses, resulted in the
increase in DTG's access revenues.   DTG cannot ensure that future changes in
the rules, both for interstate and intrastate calls, will not adversely affect
the calculated revenue requirement of, and the resulting revenues to, DTG.

     For CLECs, which include DTG's new competitive developments, there are
varying rules between federal and state jurisdictions, and substantial
uncertainty exists as to if and how the existing access charge environment (that
has historically determined revenue requirements for ILECs) should apply to
CLECs.  DTG is aware that AT&T has requested the FCC to issue a declaratory
ruling that IXCs may elect not to purchase switched access services offered
under tariff by CLECs.  AT&T claims that a substantial number of CLECs are
attempting to impose switched access charges that are higher than those charged
by ILECs in the areas where the CLECs operate.  Comments on AT&T's request were
due December 7, 1998, and reply comments are due December 22, 1998.  DTG
believes that it has, for its CLEC operations, based its filed access tariffs on
appropriate, historical allocated cost data from its ILEC operations.  DTG had
only nominal CLEC access revenues in the comparable 1997 period.  For 1998, the
CLEC access revenue has increased in 

                                      102
<PAGE>
 
direct proportion to its increase in DTG's CLEC customer base.   There can be
no assurance that future changes in the rules, both for interstate and
intrastate calls, either as a result of the AT&T petition or otherwise, will not
adversely affect the calculated revenue requirement, and the resulting revenues
to DTG from its CLEC operations.

INCOME TAXES

     DTG historically operated as a stock cooperative and was granted tax-exempt
status under Section 501(c)(12) of the Code.  Accordingly, income tax expense
was related only to certain ancillary operations, such as DTG's cable television
operations.  Beginning with DTG's conversion from a cooperative to a Delaware
corporation in July 1997, all of DTG's operations became taxable.  However,
because of DTG's consolidated net losses, DTG has accumulated income tax loss
carryovers.  See Note 4 to the DTG Interim Financial Statements for a full
discussion of DTG's income tax issues.

EFFECTS OF INFLATION

     DTG is subject the effects of inflation upon its operating costs.  DTG's
local exchange telephone operations are subject to the jurisdiction of the South
Dakota Public Utilities Commission with respect to a variety of matters,
including rates for intrastate access services and the conditions and quality of
service.  Rates for local telephone service are not established directly by
regulatory authorities, but their authority over other matters may limit DTG's
ability to implement rate increases.  In addition, the regulatory process
inherently restricts the ability of the ILEC division of DTG's operations to
immediately pass cost increases along to customers, unless the cost increases
are anticipated and the rate increases are implemented prospectively.  The CLEC
and other non-ILEC divisions of DTG are subject to competitive pressures, which
may limit DTG's ability to pass through inflation related costs to its non-
captive customer base.

     All of DTG's long-term debt from the RTFC bears interest on a floating rate
set by the RTFC on a monthly basis.  This variable rate was 6.65% at September
30, 1998.  Effective November 1, 1998, the RTFC decreased the interest rate on
all obligations with them by 0.55%. DTG has the option to fix the interest rate
on all or a portion of these loans on a quarterly basis.  Should inflation rates
significantly exceed DTG's expectations, interest rates could increase and DTG's
debt service expenses could increase beyond acceptable limits or make the RTFC
or any other lender unwilling to extend additional credit to DTG.

COMPETITION

     In February 1996, President Clinton signed into law the Telecommunications
Act. The new law represents the biggest change in the rules governing local
telephone service since Congress imposed federal regulation and established the
FCC in 1934.  Under the Telecommunications Act, the monopoly on local service
enjoyed by LECs is eliminated and LECs must allow competitors access to their
local network facilities.  DTG does not know to what extent it will be subject
to local competition in the markets it serves under the new rules. The final
results of the changes made by the new law will not be known for some time until
new rulemaking by the FCC and state regulatory agencies has been completed.  DTG
is monitoring developments regarding the new regulatory climate closely and
expects its operations may be materially affected by the new rules, but DTG
cannot predict what effect the new rules will have on its business.

     DTG is presently the only provider of local telephone service in its
historical nine local communities and directly competes with each ILEC in the
new communities it is developing. Technological developments in competing
technologies, such as cellular telephone, digital microwave, coaxial cable,
fiber optics and other wireless and wired technologies, may result in new forms
of competition to DTG's landline services.  DTG and many other members of the
local exchange carrier industry are seeking to maintain a strong, universally
affordable public telecommunications network through policies and programs that
are sensitive to the needs of small communities and rural areas 

                                      103
<PAGE>
 
served by DTG. However, there is no assurance that DTG will be able to continue
to do so in the future.

     All of DTG's cable television franchises are non-exclusive.  In addition to
competition from off-air television, other technologies also supply services
provided by cable television.  These include low power television stations,
multi-point distribution systems, over-the-air subscription television and
direct broadcast satellites.  DTG believes that cable television presently
offers a wider variety of programming at a lower cost than any competing
technology.  However, DTG is unable to predict the effect current or developing
sources of competition may have on its cable business.

     DTG's unregulated Internet, long distance, operator services and computer
network services businesses are subject to intense competition from many
different companies, many of which have substantially greater resources than
DTG.

YEAR 2000 READINESS DISCLOSURE

AN INTRODUCTION TO THE YEAR 2000 PROBLEM

     DTG is highly dependent upon advanced computer systems and specialized
software for the conduct of its business.  These systems include switching and
network operations, billing and customer care, accounting and reporting and
Internet operating systems, as well as a wide assortment of personal computer
productivity software.  In 1997, as part of its reorganization plan, DTG
installed new accounting and reporting systems and began the installation of a
new billing and customer service system, currently scheduled for completion in
1999.  It also rebuilt its Internet operating systems and installed a new
switching platform and software system.

     As part of its systems replacement process, DTG addressed an issue that is
facing all users of automated information systems.  The issue is that many
computer systems that process date sensitive information based on two digits
representing the year of the event may recognize a date using "00" as the year
1900 rather than the Year 2000.  The inability to correctly recognize "00" as
the Year 2000 could affect a wide variety of automated information systems, such
as mainframe applications, invoicing and receivables tracking systems, event
scheduling systems, personal computers and telecommunication systems, in the
form of software failure, errors or miscalculations.

     The discussion below describes DTG's efforts to address this problem.  This
Year 2000 readiness disclosure is based upon and partially repeats information
provided by DTG's outside consultants, vendors and others regarding the Year
2000 readiness of DTG and its customers, vendors and other parties.  Although
DTG believes this information to be accurate, it has not in each case
independently verified such information.

     This Year 2000 readiness disclosure is a "forward-looking statement" within
the meaning of the safe harbor provisions of the Private Securities Litigation
Reform Act of 1995. Costs, results, performance and effects of Year 2000
activities described in those forward-looking statements may differ materially
from actual costs, results, performance and effects in the future due to the
interrelationship and interdependence of DTG's computer systems and those of its
vendors, material service providers, customers and other third parties.
Readers are cautioned not to place undue reliance on the following forward-
looking statements. Furthermore, DTG undertakes no obligation to update, amend
or clarify these forward-looking statements, whether as a result of new
information, future events or otherwise.

                                      104
<PAGE>
 
YEAR 2000 COMPLIANCE PROGRAM

     It is difficult to predict with certainty what will happen to DTG's
operations when the Year 2000 date is triggered.  While DTG has received written
certifications from its vendors that its new software systems are Year 2000
compliant, given the complexity of the specialized software used by DTG and the
relative newness of the Year 2000 problem, there can be no assurance that
unanticipated operating problems will not occur in DTG's systems.  Further, like
all telecommunications companies, DTG relies on the continuing operations of
other telecommunications companies to provide worldwide communications services.
DTG must be concerned not only with its own internal systems, but also with the
inter-related systems of many other companies over which it exercises no
control.  Given these circumstances, DTG believes that it is likely that certain
of its services will be adversely affected by this problem, although the extent
and impact of these service disruptions are virtually impossible to estimate at
this time.

     In an attempt to minimize the disruption to the extent possible, DTG has
formed a Year 2000 Oversight Committee (the "Committee") with the full authority
to establish methodologies, recommend expenditures, and to marshal additional
resources as necessary to address the Year 2000 problem.  The Committee has the
full support of senior management and includes high-level representation from
many of DTG's major internal business functions. The Committee is responsible
for researching, planning, executing, implementing and completing the Year 2000
compliance goals of DTG. The systems being evaluated by the Committee include
DTG's telecommunications network   (the "Network"), which processes voice and
data information relating to its communications operations, IT internal business
systems, which include certain operational, financial and administrative
functions, and non-IT systems, which include certain systems that use embedded
micro controllers in their operation.  As discussed in more detail below, the
Committee's assessment of DTG's Year 2000 issues is not yet complete and is not
expected to be completed until next year.

     The review includes the following:

     1.   increasing employee awareness and communication of Year 2000 issues

     2.   inventorying hardware, software and data interfaces and confirming
          Year 2000 readiness of key vendors

     3.   identifying mission-critical components for internal systems, vendor
          relations and other third parties

     4.   estimating costs for remediation

     5.   estimating completion dates

     6.   correcting/remediating any identified problems

     7.   replacing systems or components that cannot be made Year 2000 ready

     8.   testing and verifying systems

     9.   implementing the remediation plan

DTG has completed approximately 40% of the activities required for the first
step of this review and approximately 29% of the activities required for the
second step. DTG is in the initial stages of performing the activities required
to complete the remaining steps and has begun to develop contingency plans to
handle its most reasonably likely worst case Year 2000 scenarios.

     A component of assessing DTG's ILEC, CLEC and cable networks includes an
assessment and survey of Year 2000 readiness of key business partners. The
network relies significantly on the provisioning and switching capabilities of
the other ILECs and IXCs in those markets in which DTG provides services.  DTG
has not received certification from these carriers indicating that they are Year
2000 compliant, but has been notified that some of the carriers have initiated
programs to

                                      105
<PAGE>
 
mitigate their Year 2000 issues in 1999.  However, there can be no assurance
that the systems of the carriers will become Year 2000 compliant before January
1, 2000.

YEAR 2000 READINESS COSTS

     To date, DTG's primary costs for its Year 2000 compliance program are
employee costs associated with DTG's internal management information systems
employees and other personnel, which DTG expenses as part of its General and
Administrative Expense. Such costs to date have not been material. DTG currently
estimates that the total cost to make DTG's internal systems Year 2000 compliant
is approximately $250,000, most of which will be expensed by DTG as the costs
are incurred.

     DTG's estimate of its Year 2000 readiness costs is a "forward-looking
statement" within the meaning of the safe harbor provisions of the Private
Securities Litigation Reform Act of 1995. Costs, results and effects of Year
2000 activities described in this forward-looking statement may differ
materially from actual costs, results and effects in the future due to the
interrelationship and interdependence of DTG's computer systems and those of its
vendors, material service providers, customers and other third parties.

CONTINGENCY PLANS

     DTG believes that the design of its network and support systems could
provide DTG with certain operating contingencies in the event material external
systems fail. DTG's major network operating facilities and systems are backed up
with auxiliary power generators believed to be capable of operating all
equipment and systems for indeterminate periods should power supplies fail.
Certain ancillary systems are backed up by emergency battery systems. In
addition, contingency plans are currently being developed to address other
problem areas. Because of the inability of DTG's contingency plans to eliminate
the negative impact that disruptions in other carriers' services would create,
there can be no assurance that DTG will not experience disruptions in its
services.

     DTG believes that with modifications to existing software and conversions
to new software, the Year 2000 issue will not pose material, unremediable
operational problems for its internal systems. However, given the current
uncertainty about the possible extent of the Year 2000 problem, management
cannot provide assurance that these efforts will be successful or that the
remediation costs will not be materially different from DTG's current estimates.
At worst case, failure by DTG or by certain of its interconnected service
providers or software vendors to remediate Year 2000 compliance issues could
result in the disruption of DTG's operations, possibly impacting operation of
the network and DTG's ability to bill or collect revenues.  A prolonged network
outage could have a material adverse effect on DTG's results of operations, cash
flows, and could possibly affect its ability to service its indebtedness.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

     In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standard No. 131, "Disclosures about Segments
of an Enterprise and Related Information" ("SFAS 131").  This pronouncement,
effective for calendar year 1998 financial statements, requires reporting
segment information consistent with the way executive management of an entity
disaggregates its operations internally to assess performance and make decisions
regarding resource allocations.  Among information to be disclosed, SFAS 131
requires an entity to report a measure of segment profit or loss, certain
specific revenue and expense items and segment assets.  SFAS 131 also requires
reconciliations of total segment revenues, total segment profit or loss and
total segment assets to the corresponding amounts shown in the entity's
consolidated financial statements.  DTG expects that the adoption of SFAS 131
will require DTG to discontinue reporting segments currently disclosed in its
annual consolidated financial statements due to the increasing convergence of
its computer, telephone and cable television businesses.

     In June 1998, the FASB issued Statement of Financial Accounting Standard
No. 133, "Accounting for Derivative Instruments and Hedging Activities" ("SFAS
133").  SFAS 133 establishes accounting and reporting standards requiring that
every derivative instrument (including certain derivative instruments embedded
in other contracts) be recorded in the balance sheet as either an asset or
liability measured at its fair value.  SFAS 133 requires that changes in the
derivative's fair value be recognized currently in earnings unless specific
hedge accounting criteria are met.  Special accounting for qualifying hedges
allows a derivative's gains and losses to offset related results on the hedged
item in the income statement, and requires that a company must formally
document, designate, and assess the effectiveness of transactions that receive
hedge accounting.

     SFAS 133 is effective for fiscal years beginning after June 15, 1999.  A
company may also implement SFAS 133 as of the beginning of any fiscal quarter
after issuance (fiscal quarters beginning June 16, 1998 and thereafter).  SFAS
133 cannot be applied retroactively.  SFAS 133 must be applied to (a) derivative
instruments, and (b) certain derivative instruments embedded in hybrid contracts
that were issued, acquired, or substantively modified after December 31, 1997
(and, at DTG's election, before January 1, 1998).

     DTG does not expect the impact of the adoption of SFAS 133 to be material
to DTG's results of operations as DTG does not currently hold any derivative
instruments or engage in hedging activities.

     No other recently issued accounting pronouncements are expected to have a
significant effect on future financial statements.

*Less than one percent

(1) The numbers of shares stated are based on information furnished by each
    person listed and include shares personally owned of record by that person
    and shares that, under applicable regulations, are considered to be
    otherwise beneficially owned by that person.  Under these regulations, a
    beneficial owner of a security includes any person who, directly or
    indirectly, through any contract, arrangement, understanding, relationship
    or otherwise has or shares voting power or dispositive power with respect to
    the security.  Voting power includes the power to vote or to direct the
    voting of the security.  Dispositive power includes the power to dispose or
    to direct the disposition of the security.  A person also will be considered
    the beneficial owner of a security if the person has a right to acquire
    beneficial ownership of the security within 60 days.

(2) In connection with the acquisitions by the Cooperative of TCIC and I-way,
    the Cooperative entered into Standstill Agreements (the "Cooperative
    Standstill Agreements") with each of the former shareholders of TCIC and I-
    way (collectively, the "Sellers"). The Sellers received shares of
    Cooperative preferred stock and warrants to purchase additional shares of
    Cooperative preferred stock. Under the Cooperative Standstill Agreements,
    the Sellers agreed to refrain from certain actions, including: (i) acquiring
    any DTG Common Stock in excess of five percent of DTG Common Stock
    outstanding at any time during the term of the Cooperative Standstill
    Agreements, with certain exceptions such as the sale or transfer of shares
    among the Sellers; (ii) making or participating in any "solicitation of
    proxies," as that term is defined in Regulation 14A under the Exchange Act;
    (iii) forming, joining or participating in a "group," as that term is
    defined in Section 13(d)(3) of the Exchange Act, with respect to any DTG
    Common Stock; (iv) initiating or participating in any stockholder proposal
    to be voted upon by the holders of DTG Common Stock or calling any special
    meeting of stockholders of DTG; (v) depositing any shares of DTG Common
    Stock into a voting trust or subjecting such shares to a voting agreement;
    or (vi) seeking in any way to gain control of DTG or the DTG Board or
    seeking to influence DTG's management or policies.

      The Cooperative Standstill Agreements further provide that the Sellers
    will not dispose of any shares of DTG Common Stock (with certain exceptions)
    except in accordance with certain provisions of the Cooperative Standstill
    Agreements. The Cooperative Standstill Agreements grant to DTG a "First
    Purchase Option" to buy all, but not less than all, of the Sellers' shares
    of DTG Common Stock that they wish to sell ("First Option Shares") for a
    period of three years following the date that the Cooperative preferred
    stock was converted into shares of DTG Common Stock. Under

                                      109
<PAGE>
 
     the First Purchase Option, if a Seller desires to sell any of the person's
     shares of DTG Common Stock, the Seller must first notify DTG, which then
     has 30 days to determine whether to purchase the First Option Shares. If
     DTG exercises its option, it must purchase all of the First Option Shares.
     If DTG does not exercise its First Purchase Option, the Seller who gave the
     notice may then sell those First Option Shares to a third party at the same
     price specified in the person's initial notice to DTG. However, if the
     Seller fails to sell the First Option Shares to a third party within 60
     days after DTG's option expires, then the process must start over.

          Under the Cooperative Standstill Agreements, in the event that a third
     party makes a tender offer (a "Tender Offer") for shares of DTG Common
     Stock, then the Sellers must grant DTG an option (the "Tender Offer
     Option") to purchase all, but not less than all, of the shares that the
     Sellers wish to sell in the Tender Offer. This process works much the same
     as for a First Purchase Option, except that the deadlines are shorter. In
     addition, if a competing tender offer arises prior to the closing of the
     sale pursuant to the Tender Offer Option at a higher per-share price, the
     Sellers can withdraw their notice of the Tender Offer Option, after which
     the process starts over. The price per share pursuant to the Tender Offer
     Option is the product of (i) the number of shares subject to the Tender
     Offer Option with respect to which DTG exercises its option, multiplied by
     (ii) the Tender Offer price per share as in effect on the last day
     specified in the Tender Offer on which the offeror may accept shares of DTG
     Common Stock for payment or exchange. If DTG fails to exercise its Tender
     Offer Option, then the Sellers can sell their shares in the Tender Offer,
     but at a price not less than that specified in the notice of the Tender
     Offer Option.

          The provisions of the Cooperative Standstill Agreements described in
     the first paragraph above apply for a period of five years beginning on
     July 25, 1997. The provisions described in the second paragraph above apply
     for three years after July 25, 1997. The Cooperative Standstill Agreements
     do not contain any specific termination provisions.

          In connection with the DataNet acquisition, DTG entered into
     Cooperative Standstill Agreements with the former shareholders of DataNet.
     The terms of these Cooperative Standstill Agreements are substantially the
     same as those of the Sellers' Cooperative Standstill Agreements with the
     exception that the various time periods, instead of running from July 25,
     1997, run from December 1, 1997.

(3)  The percentages reflected in this column were computed with reference to a
     total of 2,174,472 shares of DTG Common Stock outstanding as of November
     30, 1998 plus, where applicable, options to purchase shares of DTG Common
     Stock currently outstanding that are currently exercisable or that may be
     exercised within 60 days. The number of shares outstanding does not include
     an aggregate of 383,568 shares of DTG Common Stock that are issuable to
     former holders of Cooperative common stock and capital credit accounts upon
     satisfaction by them of the exchange and informational conditions to the
     issuance of such shares.

(4)  These numbers include shares over which the listed person is legally
     entitled to share voting or dispositive power by reason of joint ownership,
     trust or other contract or property right, and shares held by spouses and
     children over whom the listed person may have influence by reason of
     relationship.

(5)  The number of shares includes options to purchase shares of DTG Common
     Stock exercisable within 60 days held by the following persons:

                 Name                       Number of Shares

            Thomas W. Hertz                     77,648     

(6)  Includes (i) 2,000 shares awarded as outside director compensation for
     serving as a director for five years or more, issued effective January 1,
     1998, (ii) options to acquire 800 shares that are immediately exercisable
     and were granted pursuant to DTG's 1997 Stock Incentive Plan, and (iii)
     options to aquire 800 shares that are immediately exercisable that will be
     granted effective January 1, 1999 under DTG's 1997 Stock Purchase Plan.

(7)  Includes (i) shares acquired pursuant to the exercise of options granted in
     connection with the acquisitions of TCIC and I-way, (ii) options to acquire
     800 shares that are immediately exercisable and were granted pursuant to
     DTG's 1997 Stock Incentive Plan, and (iii) options to aquire 800 shares
     that are immediately exercisable that will be granted effective January 1,
     1999 under DTG's 1997 Stock Purchase Plan.

(8)  Reflects McLeodUSA Common Stock to be received in connection with the
     Merger (i) in exchange for currently owned shares of DTG Common Stock, (ii)
     in exchange for currently owned options to purchase shares of DTG Common
     Stock, and (iii) as awards made by McLeodUSA directly to certain officers
     of DTG pursuant to the Merger Agreement.

____________________

(1) To provide an incentive for Thomas W. Hertz, then Chief Executive Officer
    and General Manager of the Cooperative, and Craig A. Anderson, then
    Executive Vice President-Marketing and Chief Financial Officer of the
    Cooperative (collectively, the "Optionees"), to operate the Cooperative to
    promote the Cooperative's long-term growth and profitability and to help
    align their economic interests with those of the Cooperative's members and
    security holders, effective as of January 1, 1997, the Board of Directors of
    the Cooperative adopted stock option agreements granting options to each
    Optionee to purchase up to an aggregate of 767 shares of Cooperative
    preferred stock at a price of $1,000 per share.  Upon consummation of the
    Conversion-Merger, these options automatically became options to purchase
    DTG Common Stock (converted on an approximately 80.8-to-1 basis).  Thus, Mr.
    Anderson and Mr. Hertz each now hold options to acquire 123,980 shares of
    DTG Common Stock at a price of $6.19 per share.

    The options call for delayed vesting so that 20 percent of each option
    became exercisable on July 25, 1997. Thereafter, an additional 20 percent of
    each option becomes exercisable on each anniversary date of the stock option
    agreements if the Optionees are then employed by DTG until the total number
    of shares subject to each option become exercisable. Thus, [__] percent of
    the options are presently exercisable. Each option remains outstanding for
    10 years from the date it was granted. The options are non-transferable.

    Under the terms of the stock option agreements, the options are not
    incentive stock options under Section 422 of the Code. The options were not
    subject to tax when they were granted. Upon exercise, the Optionee will
    recognize compensation income in the amount of the spread between the market
    value of the options and the option exercise price. DTG will receive a
    corresponding deduction. The option price must be paid in cash or shares of
    stock of DTG, valued at the market value on the date of exercise.

    On a fully diluted basis, assuming that all vesting periods and other
    restrictions contained in the options have been satisfied or lapsed and all
    the options were exercised in full, each Optionee would own approximately
    5% of the total number of shares of outstanding DTG Common Stock. The
    exercise price of DTG Common Stock under the stock option agreements is
    $6.19 per share.

(1)  Based on a market value of $12.50 per share at December 31, 1997.

     During 1998, DTG compensated its directors at the rate of $500 per regular
monthly board meeting attended, $250 per special board meeting attended, $100
per special telephonic board

                                      112

meeting attended, and $250 for attendance by teleconference at regular monthly
board meetings.  Directors also are provided with travel and accident insurance
at a cost of $125 per year per director.  Directors are eligible to participate
in the medical reimbursement plan.  Directors are reimbursed for travel expenses
for attending meetings. 

     Under DTG's 1997 Stock Incentive Plan, each non-employee director of DTG is
entitled to receive semi-annually, on June 30 and December 31 of each year,
stock options to purchase 400 (as adjusted to reflect the effect of the stock
split) shares of DTG Common Stock at 100 percent of the market value on the date
of grant. The stock options will be issued for a term of 10 years. The formula
grant provisions for non-employee directors may be amended by the Board of
Directors not more than once every six months, other than to comport with
changes in the Code, the Exchange Act or the rules thereunder. Non-employee
directors may pay the exercise price using previously held shares of DTG Common
Stock to the extent that other plan participants are permitted to do so.

     In November 1997, the DTG Board adopted the Director Stock Plan of 1997,
under which each non-employee director who has or will have served more than
five years on the DTG Board (including service as a director of the Cooperative)
will receive a one-time award of 2,000 shares (as adjusted to reflect the effect
of the stock split) of DTG Common Stock. This award was payable on January 1,
1998 to directors who had previously served five years, and will be payable on
the fifth anniversary of service to all other non-employee directors.

     Employment Agreements.  DTG has separate but substantially identical
Employment Agreements ("Agreements") with Mr. Hertz and Mr. Anderson (the
"Executives"). Each Agreement is for a three-year term of employment. However,
the employment term under each Agreement will be automatically extended for an
additional year at the end of each year, unless either party gives written
notice that the employment term under the Agreement is not to be extended
further, in which case the employment term under the Agreement will expire at
the end of two additional years, except that the employment term under the
Agreement will also be extended automatically for three years following the date
of any Change in Control (as defined in the Agreements) occurring during the
employment term under the Agreement. The current terms of the Agreements are
until December 31, 2000.

     The Agreements provide minimum salaries of $135,000 per year for Thomas W.
Hertz and $100,000 per year for Craig A. Anderson, and also provide for an
annual bonus to each of the Executives equal to 15% of the increase, if any, in
corporate net income over prior year net income. "Net income," for purposes of
the bonus calculations, is pre-tax net income before depreciation, amortization
and other non-cash expenses, before annual bonuses under the two Agreements and
after eliminating the effect of extraordinary items. Under the formula, no
bonuses were paid for 1997.

     Under the Agreements, DTG or the Executive may terminate the Executive's
employment at any time upon 30 days' notice. If DTG terminates the Executive's
employment involuntarily during the employment term under the Agreements other
than as the result of a Disability or for Cause, or if the Executive terminates
the employment for Good Reason during the employment term under the Agreements,
the Agreements entitle the terminated Executive to Severance Pay. "Disability"
is defined as the Executive's inability to substantially perform his duties for
a continuous period of nine months. "Cause" is defined as willful and continued
failure by the Executive to substantially perform his duties after notice of the
deficiency, or willful misconduct by the Executive that is materially injurious
to DTG and occurs without the good-faith belief by the Executive that the 
action was in the best interests of DTG. Termination for Cause requires the
affirmative vote of two-thirds of the Board of Directors. "Good Reason" is
defined to include: (i) a material breach by DTG of the Agreements or any other
agreement with the Executive; (ii) assignment to the Executive of duties
inconsistent with his position; (iii) removal of the Executive from his
position; (iv) relocation of DTG's principal executive offices outside a 60-mile
radius from Irene, South Dakota or any requirement by DTG that the Executive be
located other than at the executive offices or that he

                                      113
<PAGE>
 
engage in substantially increased job related travel; or (v) failure of DTG to
obtain the agreement of any successor to assume the Agreements. The Executive
may not terminate his employment with Good Reason without first giving DTG
notice and ten days' opportunity to cure any occurrence constituting Good
Reason.

     "Severance Pay" under the Agreements consists of continuation of the
Executive's salary, bonus and benefits for the unexpired employment term under
the Agreements at the time of the termination (with a minimum annual bonus each
year equal to that of the year before the termination), reasonable out-placement
services and immediate vesting of all restricted stock and stock option rights.
Severance Pay is not reduced by any post-termination employment or other income
of the Executive. If the Executive dies while entitled to receive Severance Pay,
the remaining Severance Pay is to be paid to the Executive's estate.  If a
termination entitling the Executive to Severance Pay occurs after a Change in
Control, or if DTG defaults on Severance Pay obligations, the monthly salary and
bonus payments are accelerated and become payable immediately in a lump sum.

     The Agreements prohibit the Executive from competing with DTG during his
employment, and after his employment while he is receiving Severance Pay.  The
Executive may end the post-employment noncompetition period at any time by
renouncing any right to further Severance Pay.

     The Agreements provide for payment of the Executive's reasonable legal fees
and expenses incurred in seeking to enforce the Executive's rights under the
Agreements, to the extent the Executive is successful in his claims, with
payment made contemporaneously but with the Executive required to repay any
amount to which he is ultimately found not to be entitled.  The Agreements also
provide that DTG will make the Executive whole for any taxes, interest or
penalties incurred by the Executive on account of the characterization of any
payment to which the Executive is entitled from DTG as an "excess parachute
payment" under Section 280G of the Code or any successor provision of the Code,
so that the net payments to the Executive after all such taxes, interest and
penalties will be the same as if no such characterization had occurred.

     Indemnity Agreements.  DTG has entered into indemnity agreements with each
director and executive officer of DTG (collectively, "Leaders"). The indemnity
agreements indemnify each Leader against all expenses incurred in connection
with any action or investigation involving the Leader by reason of his or her
position with DTG (or with another entity at DTG's request). The Leader will
also be indemnified for costs, including judgments, fines and penalties,
indemnifiable under Delaware law or under the terms of any current or future
liability insurance policy maintained by DTG that covers the Leaders. A Leader
involved in a derivative suit will be indemnified for expenses and amounts paid
in settlement. Indemnification is dependent in every instance on the Leader
meeting the standards of conduct set forth in the indemnity agreements. If a
change in control or potential change in control occurs, DTG will fund a trust
to satisfy its anticipated indemnification obligations.

     Stock Plan Provisions.  DTG's 1997 Stock Incentive Plan provides that,
unless the DTG Board or its Compensation Committee determines otherwise, upon a
"change in control" of DTG as defined in that plan all outstanding stock option
and other awards of stock and restricted stock shall become immediately
exercisable and fully vested and nonforfeitable. In addition, upon a change in
control of DTG, the Compensation Committee may, in its discretion, determine
that some or all participants holding outstanding stock options shall receive
cash in lieu of some or all of the stock subject to such options in an amount
equal to the excess of the highest price per share actually paid in connection
with the change in control of DTG over the exercise price per share under such
options.

         MCLEODUSA CAPITAL STOCK AND COMPARISON OF STOCKHOLDER RIGHTS

     If the Merger is completed, shares of DTG Common Stock will be converted
into shares of McLeodUSA Common Stock.  As a result, DTG stockholders, whose
rights are currently governed by the DGCL, the DTG Certificate of Incorporation
and the DTG Bylaws, would become McLeodUSA stockholders, whose rights are
governed by the DGCL, the McLeodUSA Certificate of Incorporation and the
McLeodUSA Bylaws.

     The following is a description of the capital stock of McLeodUSA, including
the McLeodUSA Common Stock to be issued in the Merger, and a summary of the
material differences between the rights of DTG stockholders and McLeodUSA
stockholders. These differences arise from the differences between the governing
instruments of McLeodUSA (the McLeodUSA Certificate of Incorporation and the
McLeodUSA Bylaws) relative to the governing instruments of DTG (the DTG
Certificate of Incorporation and the DTG Bylaws). Although it is impractical to
compare all of the aspects in which the companies' governing instruments differ
with respect to stockholders' rights, the following discussion summarizes the
significant differences between them.


DESCRIPTION OF MCLEODUSA CAPITAL STOCK

     The following summary description of the capital stock of McLeodUSA does
not purport to be complete and is qualified in its entirety by the provisions of
the McLeodUSA Certificate of Incorporation and the McLeodUSA Bylaws and by the
applicable provisions of the DGCL.  For information on how to obtain copies of
the McLeodUSA Certificate of Incorporation and the McLeodUSA Bylaws, see "Where
You Can Find More Information."

AUTHORIZED AND OUTSTANDING CAPITAL STOCK OF MCLEODUSA

     Pursuant to the McLeodUSA Certificate of Incorporation, McLeodUSA has
authority to issue 274,000,000 shares of capital stock, consisting of
250,000,000 shares of McLeodUSA Common Stock, 22,000,000 shares of Class B
Common Stock, par value $.01 per share (the "McLeodUSA Class B Common Stock"),
and 2,000,000 shares of Preferred Stock, par value $.01 per share (the
"McLeodUSA Preferred Stock").  As of November 30, 1998, 63,498,849 shares of
McLeodUSA Common Stock, no shares of McLeodUSA Class B Common Stock and no
shares of McLeodUSA Preferred Stock were issued and outstanding.

     The rights of the holders of McLeodUSA Common Stock and McLeodUSA Class B
Common Stock discussed below are subject to such rights as the McLeodUSA Board
may hereafter confer on holders of McLeodUSA Preferred Stock that may be issued
in the future.  Such rights may adversely affect the rights of holders of
McLeodUSA Common Stock or McLeodUSA Class B Common Stock, or both.

MCLEODUSA COMMON STOCK

Voting Rights.  Each holder of McLeodUSA Common Stock is entitled to attend all
special and annual meetings of the stockholders of McLeodUSA and, together with
the holders of shares of McLeodUSA Class B Common Stock and the holders of all
other classes of stock entitled to attend and vote at such meetings, to vote
upon any matter (including, without limitation, the election of directors)
properly considered and acted upon by the stockholders of McLeodUSA. Holders of
McLeodUSA Common Stock are entitled to one vote per share.

Liquidation Rights.  In the event of any dissolution, liquidation or winding up
of McLeodUSA, whether voluntary or involuntary, the holders of McLeodUSA Common
Stock, the holders of McLeodUSA Class B Common Stock and holders of any class or
series of stock entitled to participate 

                                      115
<PAGE>
 
therewith, shall become entitled to participate in the distribution of any
assets of McLeodUSA remaining after McLeodUSA has paid, or provided for payment
of, all debts and liabilities of McLeodUSA and after McLeodUSA has paid, or set
aside for payment, to the holders of any class of stock having preference over
the McLeodUSA Common Stock in the event of dissolution, liquidation or winding
up the full preferential amounts (if any) to which they are entitled.

Dividends.  Dividends may be paid on the McLeodUSA Common Stock, the McLeodUSA
Class B Common Stock and on any class or series of stock entitled to participate
therewith when and as declared by the McLeodUSA Board.

No Preemptive or Conversion Rights.  The holders of McLeodUSA Common Stock have
no preemptive or subscription rights to purchase additional securities issued by
McLeodUSA nor any rights to convert their McLeodUSA Common Stock into other
securities of McLeodUSA or to have their shares redeemed by McLeodUSA.

MCLEODUSA CLASS B COMMON STOCK

Voting Rights.  Each holder of McLeodUSA Class B Common Stock is entitled to
attend all special and annual meetings of the stockholders of McLeodUSA and,
together with the holders of shares of McLeodUSA Common Stock and the holders of
all other classes of stock entitled to attend and vote at such meetings, to vote
upon any matter or thing (including, without limitation, the election of
directors) properly considered and acted upon by the stockholders of McLeodUSA.
Holders of McLeodUSA Class B Common Stock are entitled to .40 vote per share.

Liquidation Rights.  In the event of any dissolution, liquidation or winding up
of McLeodUSA, whether voluntary or involuntary, the holders of McLeodUSA Class B
Common Stock, the holders of McLeodUSA Common Stock and the holders of any class
or series of stock entitled to participate therewith, shall become entitled to
participate in the distribution of any assets of McLeodUSA remaining after
McLeodUSA has paid, or provided for payment of, all debts and liabilities of
McLeodUSA and after McLeodUSA has paid, or set aside for payment, to the holders
of any class of stock having preference over the McLeodUSA Class B Common Stock
in the event of dissolution, liquidation or winding up the full preferential
amounts (if any) to which they are entitled.

Dividends.  Dividends may be paid on the McLeodUSA Class B Common Stock, the
McLeodUSA Common Stock and on any class or series of stock entitled to
participate therewith when and as declared by the McLeodUSA Board.

Conversion Into Common Stock;  No Other Preemptive or Conversion Rights.  The
shares of McLeodUSA Class B Common Stock may be converted at any time at the
option of the holder into fully paid and nonassessable shares of McLeodUSA
Common Stock at the rate of one share of Common Stock for each share of Class B
Common Stock (as adjusted for any stock split).  Except for this conversion
right, the holders of McLeodUSA Class B Common Stock have no preemptive or
subscription rights to purchase additional securities issued by McLeodUSA nor
any rights to convert their McLeodUSA Class B Common Stock into other securities
of McLeodUSA or to have their shares redeemed by McLeodUSA.


MCLEODUSA PREFERRED STOCK

     The McLeodUSA Certificate of Incorporation authorizes the McLeodUSA Board,
from time to time and without further stockholder action, to provide for the
issuance of up to 2,000,000 shares of McLeodUSA Preferred Stock, in one or more
series, and to fix the relative rights and preferences of the shares, including
voting powers, dividend rights, liquidation preferences, redemption rights and
conversion privileges.  As of the date hereof, the McLeodUSA Board has not
provided for the issuance of any series of such McLeodUSA Preferred Stock and
there are no agreements or understandings for the issuance of any such McLeodUSA
Preferred Stock. Because of its broad discretion with respect to 

                                      116
<PAGE>
 
the creation and issuance of McLeodUSA Preferred Stock without stockholder
approval, the McLeodUSA Board could adversely affect the voting power of the
holders of McLeodUSA Common Stock and, by issuing shares of McLeodUSA Preferred
Stock with certain voting, conversion and/or redemption rights, could discourage
any attempt to obtain control of McLeodUSA.


INVESTOR AGREEMENT AND STOCKHOLDERS' AGREEMENT

     McLeodUSA has entered into an agreement (as amended, the "Investor
Agreement") with IES, MHC and Clark E. and Mary E. McLeod (collectively, the
"Investor Stockholders") and certain other stockholders. The Investor Agreement
provides that each Investor Stockholder, for so long as such Investor
Stockholder owns at least 10% of the outstanding capital stock of McLeodUSA,
shall vote such Investor Stockholder's stock and take all action within its
power to (i) establish the size of the McLeodUSA Board at nine directors; (ii)
cause to be elected to the McLeodUSA Board one director designated by IES (for
so long as IES owns at least 10% of the outstanding capital stock of McLeodUSA);
(iii) cause to be elected to the McLeodUSA Board one director designated by MHC
(for so long as MHC owns at least 10% of the outstanding capital stock of
McLeodUSA); (iv) cause to be elected to the McLeodUSA Board three directors who
are executive officers of McLeodUSA designated by Clark E. McLeod (for so long
as Clark E. and Mary E. McLeod collectively own at least 10% of the outstanding
capital stock of McLeodUSA); and (v) cause to be elected to the McLeodUSA Board
four independent directors nominated by the McLeodUSA Board. The Investor
Agreement also provides that, for a period ending in March 1999 and subject to
certain exceptions, each of IES and MHC will refrain from acquiring, or agreeing
or seeking to acquire, beneficial ownership of any securities issued by
McLeodUSA. 

     In the event that either IES or MHC becomes the beneficial owner of 50% or
more of the shares of capital stock of McLeodUSA beneficially owned by the other
(the "Acquired Investor Stockholder"), the Investor Agreement provides that
(i) the Acquired Investor Stockholder will lose the right to nominate a director
to the McLeodUSA Board, (ii) until October 23, 1999, the acquiring party (the
"Acquiring Investor Stockholder") will vote all shares beneficially owned by
such party in excess of 25% of the voting power of the outstanding capital stock
of McLeodUSA either (A) in accordance with the recommendations of the McLeodUSA
Board or (B) for or against or abstaining in the same proportion as the shares
owned by all other stockholders, (iii) the Acquiring Investor Stockholder will
cause, or use its best efforts to cause, all shares of capital stock of
McLeodUSA beneficially owned by it to be represented in person or by proxy at
all stockholder meetings through October 23, 1999, and (iv) the Acquiring
Investor Stockholder will not, and will use its best efforts to cause its
affiliates and associates not to, deposit any such shares of capital stock of
McLeodUSA in a voting trust or enter into a voting agreement or other agreement
of similar effect with any other person prior to October 23, 1999.

     In the event a third party becomes the beneficial owner of 50% or more of
the shares of capital stock of McLeodUSA beneficially owned by MHC and 50% or
more of the shares of capital stock of McLeodUSA beneficially owned by IES, the
Investor Agreement provides that IES and MHC (i) will lose the right to nominate
any directors to the McLeodUSA Board, (ii) until October 23, 1999, will vote, or
use their respective best efforts to direct the voting of, all shares
beneficially owned by such third party in excess of 25% of the voting power of
the outstanding capital stock of McLeodUSA either (A) in accordance with the
recommendations of the McLeodUSA Board or (B) for or against or abstaining in
the same proportion as the shares owned by all other stockholders, (iii) will
cause, or use their best efforts to cause, all shares of capital stock of
McLeodUSA beneficially owned by them to be represented in person or by proxy at
all meetings of McLeodUSA's stockholders through October 23, 1999, and (iv) will
not, and will use their respective best efforts to cause their affiliates and
associates not to, deposit any such shares of capital stock of McLeodUSA in a
voting trust or enter into a voting agreement or other agreement of similar
effect with any other person prior to October 23, 1999.

     On June 14, 1997, certain shareholders of CCI (collectively, the "CCI
Shareholders"), McLeodUSA and the Investor Stockholders entered into a
Stockholders' Agreement (as amended, the "Original Stockholders' Agreement"),
which became effective on September 24, 1997.  Pursuant to the Original
Stockholders' Agreement, which amends and restates the Investor Agreement among
the parties thereto, each Investor Stockholder and the CCI Shareholders, for so
long as each such party owns at least 10% of the outstanding McLeodUSA Common
Stock, shall, for a period of three years after September 24, 1997, vote such
party's shares and take all action within its power to (i) establish the size of
the McLeodUSA Board at up to eleven directors; (ii) cause to be elected to the
McLeodUSA Board one director designated by IES (for so long as IES owns at least
10% of the outstanding McLeodUSA Common Stock); (iii) cause to be elected to the
McLeodUSA Board one director designated by MHC (for so long as MHC owns at least
10% of the outstanding McLeodUSA Common Stock); (iv) cause to be elected to the
McLeodUSA Board three directors who are executive officers of McLeodUSA
designated by Clark E. McLeod (for so long as Clark and Mary McLeod collectively
own at least 10% of the McLeodUSA Common Stock); (v) cause Richard A. Lumpkin to
be elected to the McLeodUSA Board (for so long as the CCI Shareholders
collectively own at least 10% of the McLeodUSA Common Stock); and (vi) cause to
be elected to the McLeodUSA Board four non-employee directors nominated by the
McLeodUSA Board.  The Original Stockholders' Agreement provides that, for a 
period ending in June 1999 and subject to certain exceptions each of IES and MHC
will refrain from acquiring, or agreeing or seeking to acquire beneficial
ownership of any securities issued by McLeodUSA. The Original Stockholders'
Agreement also provides that, until September 24, 1998, and subject to certain
exceptions, no Investor Stockholder or CCI Shareholder will offer, sell,
contract to sell, grant any option to purchase or otherwise dispose of, directly
or indirectly, ("Transfer"), any equity securities of McLeodUSA without the
consent of the McLeodUSA Board. In addition, the Original Stockholders'
Agreement provides that if McLeodUSA grants any Investor Stockholder or CCI
Shareholder the opportunity to register equity securities of McLeodUSA under the
Securities Act, McLeodUSA will grant all other Investor Stockholders and CCI
Shareholders the same opportunity to register their pro rata portion of
McLeodUSA equity securities owned by them. The other operative provisions of the
Investor Agreement remain unchanged in the Original Stockholders' Agreement.

     On November 18, 1998, McLeodUSA entered into a Stockholders' Agreement (the
"Stockholders' Agreement") with IES, Clark E. and Mary E. McLeod, and Richard A.
Lumpkin, Gail G. Lumpkin and certain other parties affiliated or related thereto
(collectively, the "Lumpkins," and together with IES and Clark E. and Mary E.
McLeod, the "Principal Stockholders").

     The Stockholders' Agreement provides that until December 31, 2001, the
Principal Stockholders will not Transfer any equity securities of McLeodUSA, or
any other securities convertible into or exercisable for such equity securities,
beneficially owned by such Principal Stockholder without receiving the prior
written consent of the McLeodUSA Board, except for certain permitted transfers
as provided in the Stockholders' Agreement. The Stockholders' Agreement further
provides that the McLeodUSA Board shall determine on a quarterly basis
commencing with the quarter ending December 31, 1998 and ending on December 31,
2001, the aggregate number, if any, of shares of McLeodUSA Common Stock (not to
exceed in the aggregate 150,000 shares per quarter) that the Principal
Stockholders may Transfer during certain designated trading periods following
the release of McLeodUSA's quarterly or annual financial results.

     The Stockholders' Agreement provides that to the extent the McLeodUSA Board
grants registration rights to a Principal Stockholder in connection with a
Transfer of securities of McLeodUSA by such Principal Stockholder, it will grant
similar registration rights to the other parties as set forth in the
Stockholders' Agreement. In addition, the Stockholders' Agreement provides that
the McLeodUSA Board shall determine on an annual basis commencing with the year
ending December 31, 1999 and ending on December 31, 2001 (each such year, an
"Annual Period"), the aggregate number, if any, of shares of McLeodUSA Common
Stock (not to exceed in the aggregate on an annual basis a number of shares
equal to 15% of the total number of shares of McLeodUSA Common Stock
beneficially owned by the Principal Stockholders as of December 31,


                                      118
<PAGE>
 
 1998) (the "Registrable Amount"), to be registered by McLeodUSA under the
Securities Act, for Transfer by the Principal Stockholders. The Stockholders'
Agreement also provides that in any underwritten primary offering (other than
pursuant to a registration statement on Form S-4 or Form S-8 or any successor
forms thereto or other form which would not permit the inclusion of shares of
McLeodUSA Common Stock of the Principal Stockholders), McLeodUSA will give
written notice of such offering to the Principal Stockholders and will undertake
to register the shares of McLeodUSA Common Stock of such parties up to the
Registrable Amount, if any, as determined by the McLeodUSA Board. The
Stockholders' Agreement provides that McLeodUSA may subsequently determine not
to register any shares of the Principal Stockholders under the Securities Act
and may either not file a registration statement or otherwise withdraw or
abandon a registration statement previously filed.

     The Stockholders' Agreement terminates on December 31, 2001.  In addition,
if during any Annual Period McLeodUSA has not provided a Principal Stockholder a
reasonable opportunity to Transfer pursuant to the registration of securities
under the Securities Act or pursuant to certain other provisions of the
Stockholders' Agreement on the terms therein specified an aggregate number of
shares of McLeodUSA Common Stock equal to not less than 15% of the total number
of shares of McLeodUSA Common Stock beneficially owned by such Principal
Stockholder as of December 31, 1998, then such Principal Stockholder may
terminate the Stockholders' Agreement as it applies to such Principal
Stockholder within 10 business days following the end of any such Annual Period.

     The Stockholders' Agreement also contains provisions relating to the 
designation and election of directors to the McLeodUSA Board which provisions 
take effect on the terms and under the circumstances specified therein.

LIMITATION OF LIABILITY AND INDEMNIFICATION

     Limitations of Director Liability. Section 102(b)(7) of the DGCL authorizes
corporations to limit or eliminate the personal liability of directors to
corporations and their stockholders for monetary damages for breach of
directors' fiduciary duty of care. Although Section 102(b)(7) does not change
directors' duty of care, it enables corporations to limit available relief to
equitable remedies such as injunction or rescission. The McLeodUSA Certificate
of Incorporation limits the liability of directors to McLeodUSA or its
stockholders to the full extent permitted by Section 102(b)(7). Specifically,
directors of McLeodUSA are not personally liable for monetary damages to
McLeodUSA or its stockholders for breach of the director's fiduciary duty as a
director, except for liability: (i) for any breach of the director's duty of
loyalty to McLeodUSA or its stockholders; (ii) for acts or omissions not in good
faith or that involve intentional misconduct or a knowing violation of law;
(iii) for unlawful payments of dividends or unlawful stock repurchases or
redemptions as provided in Section 174 of the DGCL; or (iv) for any transaction
from which the director derived an improper personal benefit.

     Indemnification.  To the maximum extent permitted by law, the McLeodUSA
Bylaws provide for mandatory indemnification of directors and officers of
McLeodUSA against any expense, liability or loss to which they may become
subject, or which they may incur as a result of being or having been a director
or officer of McLeodUSA. In addition, McLeodUSA must advance or reimburse
directors and officers for expenses incurred by them in connection with
indemnifiable claims.

     McLeodUSA also maintains directors' and officers' liability insurance.

CERTAIN CHARTER AND STATUTORY PROVISIONS

     Classified Board.  The McLeodUSA Certificate of Incorporation provides for
the division of the McLeodUSA Board into three classes of directors, serving
staggered three-year terms.  The McLeodUSA Certificate of Incorporation further
provides that the approval of the holders of at least two-thirds of the shares
entitled to vote thereon and the approval of a majority of the entire McLeodUSA
Board are necessary for the alteration, amendment or repeal of certain sections
of the McLeodUSA Certificate of Incorporation relating to the election and
classification of the McLeodUSA Board, limitation of director liability,
indemnification and the vote requirements for such amendments to the McLeodUSA
Certificate of Incorporation.  These provisions may have the effect of deterring
hostile takeovers or delaying changes in control or management of McLeodUSA.

     Certain Statutory Provisions.  McLeodUSA is subject to the provisions of
Section 203 of the DGCL.  In general, this statute prohibits a publicly held
Delaware corporation from engaging in a "business combination" with an
"interested stockholder" for a period of three years after the date of the
transaction in which the person became an interested stockholder, unless (i)
prior to such date, the corporation's board of directors approved either the
business combination or the transaction that resulted in the stockholder
becoming an interested stockholder, (ii) upon consummation of the transaction
that resulted in such person becoming an interested stockholder, the interested
stockholder owned at least 85% of the voting stock of the corporation
outstanding at the time the transaction commenced (excluding, for purposes of
determining the number of shares outstanding, shares owned by certain directors
or certain employee stock plans), or (iii) on or after the date the stockholder
became an interested stockholder, the business combination is approved by the
corporation's board of directors and authorized by the affirmative vote (and not
by written consent) of at least two-thirds of the outstanding voting stock of
the corporation excluding that stock owned by the interested stockholder.  A
"business combination" includes a merger, asset sale or other transaction
resulting in a financial benefit to the interested stockholder.  An "interested
stockholder" is a person who (other than the corporation and any direct or
indirect wholly owned subsidiary of the corporation), together with affiliates
and associates, owns (or, as an affiliate or associate, within three years
prior, did own) 15% or more of the corporation's outstanding voting stock.

     Section 203 expressly exempts from the requirements described above any
business combination by a corporation with an interested stockholder who became
an interested stockholder at a time when the section did not apply to the
corporation.  As permitted by the DGCL, McLeodUSA's original certificate of
incorporation provided that it would not be governed by Section 203.  Certain
stockholders, including Clark E. McLeod, Mary E. McLeod, IES and MHC, became
interested stockholders within the meaning of Section 203 while that certificate
of incorporation was in effect. Accordingly, future transactions between
McLeodUSA and any of such stockholders will not be subject to the requirements
of Section 203.

     The McLeodUSA Certificate of Incorporation empowers the McLeodUSA Board to
redeem any of McLeodUSA's outstanding capital stock at a price determined by the
McLeodUSA Board, which price shall be at least equal to the lesser of (i) fair
market value (as determined in accordance with the McLeodUSA Certificate of
Incorporation) or (ii) in the case of a "Disqualified Holder," such holder's
purchase price (if the stock was purchased within one year of such redemption),
to the extent necessary to prevent the loss or secure the reinstatement of any
license, operating authority or franchise from any governmental agency.  A
"Disqualified Holder" is any holder of shares of stock of McLeodUSA whose
holding of such stock may result in the loss of, or failure to secure the
reinstatement of, any license or franchise from any governmental agency held by
McLeodUSA or any of its subsidiaries to conduct any portion of the business of
McLeodUSA or any of its subsidiaries.  Under the Telecommunications Act, non-
U.S. citizens or their representatives, foreign governments or their
representatives, or corporations organized under the laws of a foreign country
may not own, in the aggregate, more than 20% of a common carrier licensee or
more than 25% of the parent of a common carrier licensee if the FCC determines
that the public interest would be served by prohibiting such ownership.
Additionally, the FCC's rules may under certain conditions limit the size of
investments by foreign telecommunications carriers in U.S. international
carriers.

current number of McLeodUSA directors is nine. The McLeodUSA Bylaws provide that
the election and term of the McLeodUSA directors is determined pursuant to the
McLeodUSA Certificate of Incorporation. The McLeodUSA Board is divided into
three classes as nearly equal in number as possible, and the McLeodUSA directors
are elected for three-year terms by a plurality of the voting rights represented

directorships resulting from an increase in the number of directors and
vacancies resulting from resignation, removal, death, disqualification or other
incapacity shall be filled by a majority of the votes of directors then in
office whether or not a quorum and shall not be filled by the DTG stockholders.
When the number of directors is changed, any newly created or eliminated
directorship shall be apportioned among the classes of directors as to make all
classes as nearly equal in number as possible.  A decrease in the number of
directors may not shorten the term of an incumbent director.

     McLeodUSA.  Pursuant to the McLeodUSA Certificate of Incorporation,
vacancies and newly created directorships resulting from an increase in the
authorized number of McLeodUSA directors elected by all of the holders of

REMOVAL OF DIRECTORS

     DTG.  Pursuant to the DTG Certificate of Incorporation, directors may be
removed at any time by the holders of a majority of shares entitled to vote on
the election of directors, but only for cause.  "Cause" is present when (i) the
director has been convicted of a felony and such conviction is no longer subject
to direct appeal; (ii) the director has been adjudicated to be liable for
negligence or misconduct in the performance of such director's duty to the
corporation in a matter of substantial importance to the corporation and such
adjudication is no longer subject to appeal; (iii) the director has become
mentally incompetent, whether or not so adjudicated, which mental incompetence
directly affects the director's ability as a director of the corporation, or
(iv) the director's actions or failure to act have been in derogation of the
director's duties. Any proposal for removal pursuant to clauses (iii) and (iv)
initiated by the DTG Board requires the affirmative vote of at least two-thirds
of

                                      122
<PAGE>
 
the total number of directors then in office, excluding the director whose
removal is proposed and who shall not be entitled to vote thereon.

     McLeodUSA.  Neither the McLeodUSA Certificate of Incorporation nor the
McLeodUSA Bylaws includes a provision setting forth the procedure for the
removal of directors.  Under the DGCL, any director or the entire board of
directors of a corporation with a classified board, such as McLeodUSA, may be
removed by the holders of a majority of shares then entitled to vote at an
election of directors, but only for cause.

the voting rights represented by the shares issued and outstanding and entitled
to vote at the meeting, and who are present in person or represented by proxy,
shall constitute a quorum at all meetings of the stockholders for the
transaction of business.  Where a separate vote by a class or classes is
required, a majority of the outstanding shares of such class or classes, present
in person or represented by proxy, shall constitute a quorum entitled to take
action with respect to that vote on that matter.  The holders of a majority of
the voting rights represented by the shares represented at a meeting, whether or
not a quorum is present, may adjourn such meeting from time to time.

STOCKHOLDER ACTION BY WRITTEN CONSENT

     Under the DGCL, unless the corporation's certificate of incorporation
provides otherwise, any action required or permitted to be taken at any annual
or special meeting of stockholders may be taken without a meeting, without prior
notice and without a vote, if written consents are signed by the holders of
outstanding stock having not less than the minimum number of votes that would be
necessary to take such action at a meeting at which all shares entitled to vote
were present and 

                                      123
<PAGE>
 
voted. The DTG Certificate of Incorporation provides that any action required or
permitted to be taken at any annual or special meeting of stockholders may be
taken without a meeting by written consent of the holders of all shares of stock
entitled to vote thereon. The McLeodUSA Certificate of Incorporation does not
address this matter.

ADVANCE NOTICE OF STOCKHOLDER-PROPOSED BUSINESS AT ANNUAL MEETINGS

     Neither the McLeodUSA Certificate of Incorporation nor the McLeodUSA Bylaws
include a provision which requires that advance notice be given to McLeodUSA or
DTG of stockholder-proposed business to be conducted at annual meetings.  The
DTG Bylaws contain procedural requirements stockholders must follow in order to
present items for consideration at stockholder meetings.

AMENDMENT OF GOVERNING DOCUMENTS

     DTG.  DTG may amend, alter, change or repeal any provision of the DTG
Certificate of Incorporation as permitted by the DGCL.  Under the DGCL, an

of all shares entitled to vote thereon, voting together as a single class, and
the approval of a majority of the outstanding stock of each class entitled to

adoption or recommendation of DTG Board for tender offer or Business
Combination), Article XIII (liability of directors), Article XV(B) (amendment of
certificate of incorporation and Bylaws) and the DTG Bylaws; provided, however,
that this higher vote requirement shall not apply to any amendment, alteration,
modification or repeal previously approved by the affirmative votes of 80% of
the DTG Board (including the affirmative vote of at least one director from each
class of directors) and the affirmative vote of two-thirds of the Continuing
Directors. The DTG Bylaws provide that they may be amended, altered, changed or
repealed by the DTG Board at any regular or special meeting and by the
stockholders at any regular or special meeting of stockholders provided that
notice of the proposed amendment, and the proposed amendment, has been provided.

of all shares entitled to vote thereon, voting together as a single class, and

BUSINESS COMBINATION WITH AN INTERESTED STOCKHOLDER

     DTG.  The DTG Certificate of Incorporation provides that certain Business
Combinations require the affirmative vote of the holders of not less than 80% of
the outstanding shares of voting stock. Such requirement is not applicable to
any transaction that has received approval by a majority of Continuing
Directors. The voting requirements are also inapplicable (i) to Business
Combinations that either (i) have been approved by a majority of Continuing
Directors or (ii) where (a) the Business Combination will result in an
involuntary sale, redemption, cancellation or other termination of ownership of
any class of DTG voting stock held by stockholders who do not approve such
Business Combination and the aggregate amount of the cash and the market value
of other consideration to be received by such stockholders is at least equal to
the Minimum Price Per Share (as defined in the DTG Certificate of
Incorporation), (b) the consideration to be received by the holders of a
particular class of voting stock shall be paid in cash or in such other form as

stock except as approved by a unanimous vote of the directors, (3) the

shall not have received the benefit of any loans, advances, guarantees or other
financial assistance or tax credits provided by DTG nor made any major change in
DTG's business or capital structure without the unanimous approval of the DTG
Board, in either case prior to the consummation of the Business Combination; 
(d) a proxy statement under the Exchange Act shall have been mailed to all the
stockholders of DTG soliciting approval of the Business Combination; and

               CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON
                      ACCOUNTING AND FINANCIAL DISCLOSURE

     On March 27, 1997, McLeodUSA engaged the accounting firm of Arthur Andersen
LLP as McLeodUSA's principal independent accountants, to replace McGladrey &
Pullen, LLP, McLeodUSA's former independent accountants, effective with such
engagement. The decision to change independent accountants was made following a
review of competitive proposals submitted by Arthur Andersen LLP and two other
major public accounting firms, and was recommended by the Audit Committee of the
McLeodUSA Board and approved by the McLeodUSA Board.  McGladrey & Pullen, LLP
did not resign and did not decline to stand for re-election.

     During the fiscal years ended December 31, 1996 and 1995, and the interim
period between December 31, 1996 and March 27, 1997, there were no disagreements
with McGladrey & Pullen, LLP on any matter of accounting principles or
practices, financial statement disclosure, or auditing scope or procedure which
would have caused McGladrey & Pullen, LLP to make reference in their report to
such disagreements if not resolved to their satisfaction.

                                      126

     McGladrey & Pullen, LLP's reports on the financial statements of the

adverse opinion or disclaimer of opinion and were not qualified or modified as
to uncertainty, audit scope or accounting principles.

     McLeodUSA provided McGladrey & Pullen, LLP with a copy of this disclosure
and requested that McGladrey & Pullen, LLP furnish it with a letter addressed to
the SEC stating whether it agreed with the above statements. (A copy of the
McGladrey & Pullen, LLP letter addressed to the SEC is filed as Exhibit 16.1 to
McLeodUSA's Annual Report on Form 10-K for its fiscal year ended December 31,
1997, filed on March 9, 1998).

proxy statement for the 1999 Annual Meeting of Stockholders of DTG, such
proposals must have been received by the Secretary of DTG on or before November

Board of Directors
Dakota Telecommunications Group, Inc.
  and Subsidiaries
Irene, South Dakota


We have audited the accompanying consolidated balance sheet of Dakota
Telecommunications Group, Inc. (incorporated in Delaware and formerly Dakota
Cooperative Telecommunications, Inc.) and subsidiaries as of December 31, 1997,
and 1996, and the related consolidated statements of operations, stockholders'
equity and cash flows for the years then ended.  These financial statements are
the responsibility of the Company's management.  Our responsibility is to
express an opinion on these financial statements based on our audits.

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

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Dakota
Telecommunications Group, Inc. and subsidiaries as of December 31, 1997, and
1996, and the results of their operations and their cash flows for the years
then ended, in conformity with generally accepted accounting principles.

H.  Property, Plant and Depreciation - Property, plant and equipment are
    --------------------------------
recorded at original cost. Additions, improvements or major renewals are
capitalized. If the telecommunication and cable television utility plant is
sold, retired or otherwise disposed of in the ordinary course of business, the
cost plus removal costs less salvage, is charged to accumulated depreciation.

Depreciation is computed using principally the straight-line method based upon
the estimated service lives of the depreciable assets.

I.  Excess of Cost Over Net Assets Acquired - The excess of cost over net assets
    ---------------------------------------                                     
of acquired companies is being expensed equally over fifteen years and is shown
net of accumulated amortization of $150,030 and $10,032 at December 31, 1997,
and 1996.

J.  Other Intangible Assets - Other intangible assets consist of customer lists
    -----------------------                                                    
($628,026 and $541,300 as of December 31, 1997, and 1996) and is being expensed
equally over fifteen years and shown net of accumulated amortization of $73,193
and $31,741 at December 31, 1997, and 1996.  Other intangible assets also
include the cost ($255,010) of a Broadband Personal Communications Service
System license at December 31, 1997.

K.  Other Investments - Other investments are recorded at cost.
    -----------------                                          

L.  Capital Credits - The Company operated as a cooperative until July 21, 1997.
    ---------------
Amounts received from the furnishing of telephone service, interest income and
other nonoperating operations in excess of costs and expenses were assigned to
telephone patrons on a patronage basis to the extent they were not needed to
offset prior losses.

M.  Revenue Recognition - Revenues are recognized when earned, regardless of the

period in which they are billed.  Network access and long distance revenues are
furnished in conjunction with interexchange carriers and are determined by cost
separation studies.  Revenues include estimates pending finalization of cost
studies.  Network access revenues are based upon interstate tariffs filed with
the Federal Communications Commission by the National Exchange Carriers
Association and state tariffs filed with state regulatory agencies.  Management
believes recorded revenues are reasonable based on estimates of final cost
separation studies which are typically settled within two years.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

N.  Income Taxes -  Until July 21, 1997, the Parent Company operated as a
    ------------                                                         
cooperative and had been granted tax exempt status under Section 501(c)12 of the
Internal Revenue Code; therefore the Parent Company income was not taxable.  The
State of South Dakota does not have an income tax.

After July 21, 1997, the Parent Company became subject to federal income taxes
and files a consolidated return with its wholly-owned subsidiaries, which are
subject to federal income taxes and Minnesota and Iowa income taxes for
operations in those states.  Income taxes for these companies are provided for
the tax effects of transactions reported in the financial statements and include
taxes currently payable and deferred income taxes which reflect the estimated
income tax consequences of the differences between the income tax bases of
assets and liabilities and their financial reporting bases.  Temporary
differences are primarily depreciation and net operating losses carryforwards.

O.  Credit Risk - Financial instruments which potentially subject the Company to
    -----------                                                                 
concentrations of credit risk consist principally of temporary cash investments.
The Company places its temporary cash investments with high credit quality
financial institutions and, by policy, generally limits the amount of credit
exposure to any one financial institution. Concentrations of credit risk with
respect to trade receivables are limited due to the Company's large number of
customers.  The Company maintains its cash in bank deposit accounts which, at
times, may exceed federally insured limits.  The Company has not experienced any
losses in such accounts.  The Company believes it is not exposed to any
significant credit risk.

P.  Allowance for Funds Used During Construction - The Company includes in its
    --------------------------------------------                              
telecommunication and cablevision plant accounts an average cost of debt used
for the construction of the plant, and excludes the amounts from interest
expense on the statement of operations.  The amount capitalized for 1997 was
$171,800.

Q.  Reclassifications - Certain reclassifications have been made to the 1996
    -----------------                                                       
financial statements to conform to the 1997 presentation.  These
reclassifications had no effect on net income.


NOTE 2 - REORGANIZATION

At a special meeting of the stockholders on July 21, 1997, an amendment to the
Company's articles of incorporation was approved which resulted in the
conversion of the Company from a cooperative to a South Dakota business
corporation.  Also at a meeting convened on July 21, 1997, and subsequently
adjourned and completed on July 25, 1997, the shareholders of the South Dakota
business corporation approved an Agreement and Plan of Merger that provided for
the subsequent merger of the South Dakota business corporation with and into the
Company.  The conversion of equity in the Cooperative to equity in the South
Dakota business corporation and then into equity in the Company was at the rate
of one share of common stock for each share of the Cooperative's common stock,
80.8216445 shares of common stock for each share of preferred stock and 0.2 of a
share of common stock for each dollar of capital credits.

NOTE 6 - LONG-TERM DEBT (Continued)

The Company received loans of $14,737,000 and $13,684,000 from RTFC for the
purposes of refinancing its RUS debt and RTFC lines of credit and to finance
plant construction.  The loans are payable quarterly, with full payment due in
fifteen years.  On July 15, 1997, the Company retired its entire RUS debt with
loan proceeds from RTFC.  In order to obtain financing from RTFC, the loans
include borrowings of $1,449,185 to purchase Subordinated Capital Certificates
(SCC) of RTFC.  The SCCs bear no interest and will be repaid to the Company.
SCCs are included in other investments on the balance sheet.  The Company is
required to maintain a debt service coverage of not less than 1.25 and a times
interest earned ratio of not less than 1.50.  Each ratio is determined by
averaging the two highest annual calculations during the three most recent
fiscal years.  The Company is restricted from incurring any additional unsecured
debt in excess of five percent of total assets from any other lender and from
declaring or paying any dividend or purchasing or redeeming any capital stock in
excess of 25 percent of the prior fiscal year-end cash margins without written
approval of the lender.

Unadvanced loan funds of $94,181 are available to the Company on loan
commitments from RTFC.  Loan proceeds will be used to finance future
construction.  The RTFC loans, maturing in 2012, are collateralized by all
assets, revenues and stock of the Company's subsidiaries.  The RTFC loan,
maturing in 2006, is collateralized by the cable plant located in ten cities in
southeastern South Dakota and is payable in quarterly installments.

The loan from Home Federal Savings Bank is guaranteed by the Company and is
payable by the Company's ESOP in ten equal installments beginning in 1998.

Approximate annual principal payments on the existing debt for the next five

On December 16, 1997, the Board of Directors declared a two-for-one common stock

for the stock split.

As of December 31, 1996, the Company's common stock had a par value of $5 per
share.  There were 15,000 shares authorized.  No person could own more than one
share of common stock and each holder of common stock had one vote in the
affairs of the Company.

Nonvoting preferred stock had a par value of $100 per share and there were
63,000 shares authorized.  The preferred stock is shown on the balance sheet at

NOTE 7 - CAPITAL STOCK (Continued)

At December 31, 1996, and 1997, there were warrants outstanding which may be
exercised through January 21, 1998, to purchase 482 shares of preferred stock
which were converted to 77,912 shares of common stock.  These warrants were
exercised on January 21, 1998.  Effective January 1, 1997, the Company granted
management options to purchase up to 1,534 shares of preferred stock at $1,000 a
share which were replaced with common stock under the Executive Stock Option
Plan.

As of December 31, 1997, the Company has 5,000,000 shares of no par common stock
authorized and 1,542,348 shares are issued and outstanding.  The Company also
has 250,000 shares of no par preferred stock of which 15,000 shares are
designated as Series A Junior Participating Preferred Stock.  No preferred stock
is outstanding as of December 31, 1997.

Former holders of Cooperative common stock and capital credit accounts are
entitled to receive shares of common stock of the Company, without any further
consideration, upon receipt by the Company of properly executed transmittal
documents in acceptable form.  If all such persons had satisfied the conditions
to receive shares at December 31, 1997, a total of 911,320 additional shares of
the Company's common stock would have been issued and outstanding at that date.
Other capital includes that amount of stockholders equity which would have been
included in common stock if those shares had been issued and outstanding at
December 31, 1997.

On July 22, 1997, the Board of Directors adopted a leveraged employee stock
ownership plan ("ESOP").  The ESOP purchased 98,426 shares of common stock for
$1,000,000 in December 1997.  The purchase price per share is approximately the
same as fair value per share at December 31, 1997, based upon an appraisal.
Under the terms of the Plan, employees who are not part of a collective
bargaining unit, a leased employee or a nonresident alien and have completed at
least 1,000 hours of service become eligible to participate in the plan.  The
Company determines the amount of contributions that will be made each year.  The
contribution is allocated among eligible participants based on compensation in
proportion to total compensation paid to all eligible participants.  Any
dividends earned will be allocated to the participant's account based on
allocated shares.  A participant becomes fully vested after five years of
service or upon normal retirement date.  No contributions were made to the ESOP
in 1997.

On July 22, 1997, the Board of Directors declared a dividend of one right for
each outstanding share of common stock to common stockholders of record on
August 5, 1997.  Each right allows the holder to purchase one one-hundredth of a
share of Series A Junior Participating Preferred Stock.  The exercise price of
the rights are $100 per right and the redemption price is $.01.  The rights
expire August 4, 2007.

In July 1997, the Company adopted the 1997 Stock Incentive Plan that provides
for stock options, stock appreciation rights, restricted stock, stock awards and
tax benefit rights for key employees and provides for automatic awards of stock
options to nonemployee directors of the Company which expire ten years after
being granted.  The Company has reserved 350,000 shares of common stock for this
plan.

In November 1997, the Company adopted the Director Stock Plan of 1997 that
provides that stock may be awarded to outside directors upon their fifth
anniversary of service as an outside director.  The Company has reserved 40,000
shares of common stock for this plan.

NOTE 7 - CAPITAL STOCK (Continued)

In November 1997, the Company adopted the Executive Stock Option Plan of 1997
that provides that options for 247,960 shares of common stock may be awarded to
officers and other key employees of the Company which expire ten years after
being granted.  Options for 247,960 shares of common stock were granted under
this plan to replace preferred stock options for 1,534 shares at $1,000 per
share.

At December 31, 1997, there were options for 285,640 shares outstanding which
were granted during 1997.  Exercise prices of outstanding stock options are
267,640 shares at $6.19 and 18,000 shares at $12.50 per share.  The average
exercise price is $6.59 per share.  The average remaining life of outstanding
stock options at December 31, 1997, was 6.12 years.  Options exercisable at
December 31, 1997, are 53,528 shares at $6.19 and 6,480 shares at $12.50 per
share.

The Company has adopted the disclosure provisions of SFAS No. 123, "Accounting
for Stock-Based Compensation", but applies APB Opinion No. 25, "Accounting for
Stock Issued to Employees" for measurement and recognition of stock-based
transactions with its employees.  If the Company had elected to recognize
compensation cost for its stock based transactions using the method prescribed
by SFAS No. 123, net loss and loss per share since reorganization would have
been $(1,782,202) and $(1.47).

The fair value of the Company's stock options used to compute pro forma net loss
and net loss per share disclosures is the estimated present value at grant date
using the Black-Scholes option-pricing model with the following assumptions:
expected volatility of 30%, a risk free interest rate of 5.70% to 6.33%, an
expected holding period of seven years and no dividend yield.  Pro forma stock-
based compensation cost was $150,000 in 1997.

The Company approved an offering of 400,000 shares of common stock at a purchase
price of $12.50 per share to shareholders and employees as of January 27, 1998.
The offering expires on March 11, 1998.


NOTE 8 - FAIR VALUE OF FINANCIAL INSTRUMENTS

The carrying value of cash and temporary cash investments approximates their
fair value due to the short maturity of the instruments.  The fair value of the
Company's long-term debt at December 31, 1997, is estimated to be approximately
equal to the carrying value of $29,200,469.  The fair value of the Company's
long-term debt at December 31, 1996, after deducting current maturities, is
estimated to be $12,905,145, compared to carrying values of $15,338,395.  The
fair value estimates are based on the overall weighted rates and maturity
compared to rates and terms currently available in the long-term financing
markets.

On December 7, 1994, the Company and its wholly-owned subsidiary, Dakota
Telecommunications Systems, Inc., entered into an agreement with U S West
Communications, Inc. to purchase the assets and acquire the right to provide and
operate wireline telecommunication services in eight exchanges in the state of
South Dakota for $10,144,884. In 1996, the Company canceled the agreement. The

written down by $274,889 to the estimated recoverable amount of $274,889, which
was received in 1997. In addition, the Company expensed $275,252 of related
acquisition costs in 1996.

At December 31, 1997, the Company had net deferred tax assets primarily as a
result of the net operating losses.  The full amount of the net deferred tax
asset was offset by a valuation allowance due to uncertainties relating to the
full future utilization of these net operating losses.

The differences between the statutory federal rate and the effective tax rate
were as follows:

NOTE 14 - CHANGE IN ACCOUNTING ESTIMATE

NOTE 14 - CHANGE IN ACCOUNTING ESTIMATE (Continued)

Effective February 1, 1996, the Company revised its estimate of the useful lives
of cable television plant.  Previously the plant was depreciated over 20 years.
The revised useful life of the plant ranges from eight to twenty years.  These
changes were made to better reflect the estimated periods during which such
assets will remain in service.  The 1996 changes increased depreciation expense
by approximately $189,000 in 1996.

NOTE 15 - LOSS PER SHARE

Basic loss per share was computed by dividing the net loss of $(1,632,202) for
only the period since the reorganization (July 21, 1997, to December 31, 1997)
by the weighted average number of common shares outstanding (1,213,442 shares)
during the period since the reorganization adjusted for the two-for-one stock
split.  Shares issued as a result of the reorganization were considered
outstanding for the entire period. Net loss of $(854,585) for the period prior
to the reorganization was not considered in the loss per share calculation.

Options, rights and warrants have not been considered in the computation of
diluted loss per share since their effect would be anti-dilutive because of the
net loss.  If the 911,320 shares issuable at December 31, 1997, to former
holders of Cooperative common stock and capital credit accounts upon
satisfaction by such holders of conditions to issuance, which have not been
issued as a result of the reorganization, were considered issued for the entire
period, the loss per share would have been $(.77).

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)

NOTE 1 - CONSOLIDATED FINANCIAL STATEMENTS

The balance sheets as of September 30, 1998 and December 31, 1997, statements of
operations for the three and nine months ended September 30, 1998 and 1997 and
cash flows for the nine months ended September 30, 1998 and 1997 have been
prepared by the Company without audit. In the opinion of management, all
adjustments (consisting only of normal recurring accruals) necessary to present
fairly the financial position, results of operations and changes in cash flows
have been made.

The Consolidated Financial Statements have been prepared in accordance with the
requirements of Item 301(b) of Regulation S-B and with the instructions to Form
10-QSB. Accordingly, certain information and footnote disclosures normally
included in financial statements prepared in accordance with generally accepted
accounting principles have been condensed or omitted. These condensed financial
statements should be read in conjunction with the financial statements and
accompanying notes for the years ended December 31, 1997 and 1996. The results
of operations for the three- and nine-month periods ended September 30, 1998 are
not necessarily indicative of the operating results to be expected for the year
ending December 31, 1998.

NOTE 2 - NOTES PAYABLE

The Company has a line of credit arrangement for $1.5 million with Rural
Telephone Finance Cooperative ("RTFC") which expires in 2002. Interest is
payable quarterly at variable monthly rates determined by RTFC with a cap at
prime plus 1.5%. Any advances must be paid in full within 360 days of the
advance and remain at a zero balance for at least five consecutive business
days. A balance of $1,500,000 was outstanding as of September 30, 1998.

In October 1998, the Company's secured line of credit arrangement for $4 million
with RTFC was increased to $6 million and expires January 1, 2000.  Interest is
payable quarterly at variable monthly rates based on the prevailing bank prime
rate plus 1.5%.  A balance of $2,400,000 was outstanding as of September 30,
1998.

The $800,000 line of credit with Norwest Bank which would have expired on April
1, 1999 was replaced by a new line of credit agreement with Norwest dated
September 10, 1998 for a maximum of $2,000,000 at the prime rate plus one and
one half percent expiring September 3, 2001, at which point it may be renewed on
an annual basis thereafter. This line of credit is secured by essentially all of
the assets of DTG DataNet, Inc., a wholly owned subsidiary of the Company. The
amount outstanding at September 30, 1998 was $662,573.

NOTE 3 - PAYABLE UNDER FLOOR PLAN ARRANGEMENT

The Company's additional $500,000 credit limit for the floor plan arrangement
with the IBM Credit Corporation expired August 31, 1998. The amount outstanding
at September 30, 1998 on the original $350,000 agreement was $113,902. The
Company also had $433,854 outstanding on another floor plan arrangement as of
September 30, 1998.

                                  (UNAUDITED)

NOTE 4 - INCOME TAXES

As of July 22, 1997, the income of the Company became taxable at the federal
level. Prior to that date, the Company operated as a cooperative and had been
granted tax exempt status under Section 501(c)12 of the Internal Revenue Code of
1986, as amended.

At September 30, 1998 and December 31, 1997, the Company had net deferred tax
assets primarily as a result of the net operating losses. The full amount of the
net deferred tax asset was offset by a valuation allowance due to uncertainties
relating to the future utilization of these net operating losses. The tax
benefit of $8,000 at September 30, 1998 is due to additional refunds receivable
for net operating losses that can be applied against income in a prior year.

NOTE 5 - ACQUISITIONS

On July 1, 1998, the Company purchased the outstanding stock of Vantek
Communications, Inc. and Van/Alert, Inc. in exchange for 48,000 shares of the
Company's stock valued at $12.50 per share, long-term debt of $250,000 and
$250,000 in cash. The debt is convertible into Company stock. The acquisition
resulted in an excess of cost over net assets acquired of $1,046,919. This
amount is being amortized over 15 years.

The long-term debt of $250,000 at 9% interest is payable in monthly installments
of $5,190 until July 1, 2003.

NOTE 6 - CAPITAL STOCK

At September 30, 1998 and December 31, 1997 the number of shares of common stock
outstanding were 2,692,321 and 1,542,348, respectively.

Former holders of common stock and capital credit accounts of Dakota Cooperative
Telecommunications, Inc. (the "Cooperative") are entitled to receive shares of
common stock of the Company, without any further consideration, upon receipt by
the Company of properly executed transmittal documents in acceptable form. If
all such persons had satisfied the conditions to receive shares at September 30,
1998 and December 31, 1997, a total of 395,376 and 911,320 additional shares of
the Company's common stock, respectively, would have been issued and outstanding
as of those dates. Other capital includes that amount of stockholders' equity
that would have been included in common stock if those shares had been issued
and outstanding at September 30, 1998 and December 31, 1997.

The Company approved an offering of 400,000 shares of common stock at a purchase
price of $12.50 per share to existing shareholders and employees as of January
27, 1998. The offering expired on March 11, 1998 and 19,485 shares of common
stock were issued.

At the annual meeting, the shareholders approved an amendment to the Company's
Certificate of Incorporation to increase the authorized number of shares of
common stock from 5,000,000 to 10,000,000.

NOTE 8 - LOSS PER SHARE

Basic and diluted loss per share as of September 30, 1998 was based on the
average number of shares of common stock outstanding during the periods. Shares
issued as a result of the reorganization were considered outstanding for the
entire period. The number of shares used in the calculation was 2,692,321 and
2,321,272 for the three months and nine months ended September 30, 1998. No
shares were outstanding as of September 30, 1997.

Options, rights and warrants have not been considered in the computation of
diluted loss per share since their effect would be anti-dilutive because of the
net loss. If the 395,376 shares issuable at September 30, 1998 to former holders
of Cooperative common stock and capital credit accounts upon satisfaction by
such holders of conditions to issuance, which have not been issued as a result
of the reorganization, were considered issued for the entire period, the loss
per share would have been $1.41 for the nine months ended, and $.45 for the
three months ended, September 30, 1998.

If the 1, 970,432 shares issuable at September 30, 1997 to former holders of
Cooperative common stock and capital credit accounts upon satisfaction by such
holders of conditions to issuance, which have not been issued as a result of the
reorganization, were considered issued for the entire period, the basic and
diluted loss per share would have been $(.35) for the three months and nine
months ended September 30, 1997.

Basic and diluted loss per share as of September 30, 1997 was computed by
dividing the net loss of $(680,326) for only the period since the reorganization
(July 21, 1997 to September 30, 1997) by the weighted average number of common
shares issuable (1,970,432 shares) during the period since the reorganization
adjusted for the two-for-one stock split. Shares issuable as a result of the
reorganization were considered outstanding for the entire period. Net loss of
$(854,585) for the period prior to the reorganization was not considered in the
loss per share calculation.

Options, rights and warrants have not been considered in the computation of
diluted loss per share since their effect would be anti-dilutive because of the
net loss.

NOTE 9 - COMMITMENTS

The Company has made commitments to provide cable access television service to
the cities of Luverne and Marshall, Minnesota and Canton, South Dakota. These
cities have required that bonds and financial securities be provided to ensure
performance by the Company. The Company has obtained $832,500 in irrevocable
letters of credit to fully cover these requirements.

NOTE 10 - SUBSEQUENT EVENTS

On October 27, 1998, the Board of Directors approved an Agreement and Plan of
Merger with McLeodUSA Incorporated, pursuant to which the Company will be merged
with and into a wholly owned subsidiary of McLeodUSA Incorporated (the
"Merger"). All of the stock of the Company and each right to receive one share

McLeodUSA Incorporated common stock to be issued is 1,295,000. The Merger is
subject to stockholder and regulatory approval. The Merger agreement requires
the Company to pay McLeodUSA Incorporated a $2,500,000 penalty if alternative
offers are pursued.

On April 24, 1998, the Company entered into a Merger Agreement to purchase the

     Common Stock issuable pursuant to the Merger as contemplated under this
     Merger Agreement shall be 1,295,000 (assuming the exercise of all Company
     Stock Options (as defined in Section 2.04) prior to the Effective Time).
     All such shares of Company Common Stock, Conversion-Merger Rights
     (including unexchanged Cooperative Interests) and associated Rights shall
     no longer be outstanding and shall automatically be canceled and retired,
     as appropriate, and shall cease to exist, and each certificate or other
     instrument previously representing any such shares, Conversion-Merger
     Rights (including unexchanged Cooperative Interests) and associated Rights
     shall thereafter represent the right to receive a certificate representing
     the shares of Acquiror Common Stock into which such Company Common Stock,
     Conversion-Merger Rights and associated Rights were converted pursuant to
     the Merger and any cash, without interest, in lieu of fractional shares.
     Certificates or other instruments which prior to the Effective Time
     represented shares of Company Common Stock, Conversion-Merger Rights
     (including certificates or other instruments which prior to the Conversion-
     Merger represented Cooperative Interests) and associated Rights shall be
     exchanged for certificates representing whole shares of Acquiror Common
     Stock issued in consideration therefor upon the surrender of such
     certificates or instruments in accordance with the provisions of Section
     2.02, without interest.  No fractional share of Acquiror Common Stock shall
     be issued, and, in lieu thereof, a cash payment shall be made pursuant to
     Section 2.02(e) hereof.  In any event, if between the date of this Merger
     Agreement and the Effective Time the outstanding shares of Acquiror Common
     Stock shall have been changed into a different number of shares or a
     different class, by reason of any stock dividend, subdivision,
     reclassification, recapitalization, split, combination or exchange of
     shares, the nature of the consideration to be received by the Company
     Stockholders and the Exchange Ratio shall be appropriately and
     correspondingly adjusted to reflect such stock dividend, subdivision,
     reclassification, recapitalization, split, combination or exchange of
     shares.

     2.01(c)), Conversion-Merger Rights (including unexchanged Cooperative
     Interests) and associated Rights referred to in Section 2.01(a) shall no
     longer be outstanding and shall automatically be canceled and retired, as
     appropriate, and shall cease to exist, and each certificate or other
     instrument previously representing any such shares, Conversion-Merger
     Rights (including unexchanged Cooperative Interests) and associated Rights
     shall thereafter represent the right to receive the shares of Acquiror
     Common Stock into which such Company Common Stock, Conversion-Merger Rights
     (including unexchanged Cooperative Interests) and associated Rights were

                                      -4-

     converted pursuant to the Merger and any cash, without interest, in lieu of
     fractional shares.  The holders of certificates or other instruments which
     prior to the Effective Time represented shares of Company Common Stock,
     Conversion-Merger Rights (including the holders of certificates or other
     instruments which prior to the Conversion-Merger represented Cooperative
     Interests) and associated Rights shall cease to have any rights with
     respect thereto except as otherwise provided herein or by Law.
     Certificates or other instruments previously representing such shares of
     Company Common Stock, such Conversion-Merger Rights (including certificates
     or other instruments previously representing such Cooperative Interests)
     and associated Rights shall be exchanged for the whole shares of Acquiror
     Common Stock to be issued therefor upon the surrender of such certificates
     or instruments in accordance with the provisions of Section 2.02, without
     interest.  No fractional share of Acquiror Common Stock shall be issued,
     and, in lieu thereof, a cash payment shall be made pursuant to Section
     2.02(e) hereof.

          (c)  Cancellation of Treasury Stock.  Any shares of Company Common
               ------------------------------                               
     Stock held in the treasury of the Company and any shares of Company Common
     Stock owned by Acquiror or any direct or indirect wholly owned subsidiary
     of Acquiror or of the Company immediately prior to the Effective Time shall
     be canceled and extinguished without any conversion thereof and no payment
     shall be made with respect thereto.

          (d)  Acquiror Sub Common Stock.  Each share of common stock, par value
               --------------------------                                       
     $0.01 per share, of Acquiror Sub issued and outstanding immediately prior
     to the Effective Time shall be converted into and exchanged for one newly
     and validly issued, fully paid and non-assessable share of common stock of
     the Surviving Corporation.

     SECTION 2.02.  EXCHANGE OF CERTIFICATES OR INSTRUMENTS.

          (a)  Exchange Agent. As of the Effective Time, Acquiror shall deposit,

or shall cause to be deposited, with Norwest Bank Minnesota, N.A., or another
bank or trust company designated by Acquiror and reasonably acceptable to the
Company (the "Exchange Agent"), for the benefit of the holders of issued and
              --------------                                                
outstanding Company Common Stock and associated Rights for exchange through the
Exchange Agent in accordance with this Article II, certificates representing the
whole shares of Acquiror Common Stock issuable to such holders pursuant to
Section 2.01 and cash in an amount sufficient to permit payment of the cash
payable in lieu of fractional shares pursuant to Section 2.02(e) (such
certificates for shares of Acquiror Common Stock, together with any dividends or
distributions with respect thereto, and such amounts of cash, being hereafter
referred to as the "Exchange Fund").  As of the Effective Time, Acquiror shall
                    -------------                                             
reserve and keep available out of its authorized and unissued Acquiror Common
Stock, the number of shares of Acquiror Common Stock that will be sufficient to
permit the exercise and

                                      -5-
<PAGE>
 
exchange in full of all Conversion-Merger Rights outstanding immediately prior
to the Effective Time.  The Exchange Agent shall, pursuant to irrevocable
instructions from Acquiror, deliver the shares of Acquiror Common Stock to be
issued and the amount of cash to be paid to the holders of Company Common Stock
and associated Rights pursuant to Section 2.01 out of the Exchange Fund.

          (b)  Exchange Procedures.  Promptly (and, in any event, within seven
               -------------------                                            
(7) business days) after the Effective Time, Acquiror shall use its reasonable
best efforts to cause the Exchange Agent to mail to each holder of record of a
certificate or certificates of Company Common Stock which immediately prior to
the Effective Time represented outstanding shares of Company Common Stock and
associated Rights and to each holder of record of a certificate or certificates
or other instrument or instruments representing Conversion-Merger Rights
(including unexchanged Cooperative Interests) which immediately prior to the
Effective Time represented the right to receive shares of Company Common Stock
and associated Rights (all such certificates and instruments, the
"Certificates") (i) a letter of transmittal (which shall specify that delivery
 ------------                                                                 
shall be effected, and risk of loss and title to the Certificates shall pass,
only upon proper delivery of the Certificates to the Exchange Agent (in the case
of Certificates representing Company Common Stock) or Acquiror (in the case of
Certificates representing Conversion-Merger Rights) and shall be in customary
form) and (ii) instructions for use in effecting the surrender of the
Certificates in exchange for certificates representing shares of Acquiror Common
Stock.  Upon surrender of a Certificate for cancellation to the Exchange Agent
(in the case of Certificates of Company Common Stock) or Acquiror (in the case
of Certificates representing Conversion-Merger Rights), as specified in such
letter of transmittal, together with such letter of transmittal, duly executed,
and such other Documents as may reasonably be required pursuant to such
instructions, the holder of such Certificate shall be entitled to receive
promptly in exchange therefor a certificate representing that number of whole
shares of Acquiror Common Stock which such holder has the right to receive in
respect of such Certificate (after taking into account all shares of Company
Common Stock and Conversion-Merger Rights then held by such holder under all
such Certificates so surrendered), together with any dividends or other
distributions to which such holder is entitled pursuant to Section 2.02(c) and
cash in lieu of fractional shares of Acquiror Common Stock to which such holder
is entitled pursuant to Section 2.02(e), and the Certificate so surrendered
shall forthwith be canceled.  In the event of a transfer of ownership of shares
of Company Common Stock or Conversion-Merger Rights which is not registered in
the transfer records of the Company, the proper number of shares of Acquiror
Common Stock may be issued and the proper amount of cash may be paid pursuant
hereto to a transferee if the Certificates representing such shares of Company
Common Stock or Conversion-Merger Rights, properly endorsed or otherwise in
proper form for transfer, are presented to the Exchange Agent (in the case of
Certificates representing Company Common Stock) or Acquiror (in the case of
Certificates representing Conversion-

                                      -6-

Merger Rights), accompanied by all Documents required to evidence and effect
such transfer and by evidence that any applicable stock transfer taxes have been
paid.  Until surrendered as contemplated by this Section 2.02, each Certificate
shall be deemed at any time after the Effective Time to represent only the right
to receive upon such surrender the shares of Acquiror Common Stock issuable in
exchange therefor, together with any dividends or other distributions to which
such holder is entitled pursuant to Section 2.02(c) and cash in lieu of any
fractional shares of Acquiror Common Stock to which such holder is entitled
pursuant to Section 2.02(e).  No interest will be paid or will accrue on any
cash payable pursuant to Sections 2.02(c) or 2.02(e).

Effective Time with respect to Acquiror Common Stock with a record date after
the Effective Time shall be paid to the holder of any unsurrendered Certificate
with respect to the whole shares of Acquiror Common Stock represented thereby,
and no cash payment in lieu of fractional shares shall be paid to any such
holder pursuant to Section 2.02(e), until the holder of such Certificate shall
surrender such Certificate.  Subject to the effect of escheat, tax or other
applicable Laws, following surrender of any such Certificate, there shall be
paid to the record holder of the certificates representing whole shares of
Acquiror Common Stock issued in exchange therefor, without interest, (i)
promptly, the amount of any cash payable with respect to a fractional share of
Acquiror Common Stock to which such holder is entitled pursuant to Section
2.02(e) and the amount of dividends or other distributions with a record date
after the Effective Time theretofore paid with respect to such whole shares of
Acquiror Common Stock, and (ii) at the appropriate payment date, the amount of
dividends or other distributions, with a record date after the Effective Time
but prior to surrender and a payment date occurring after surrender, payable
with respect to such whole shares of Acquiror Common Stock.

          (d)  No Further Rights in Company Common Stock and Conversion-Merger

shares of Company Common Stock, the Conversion-Merger Rights and the associated
Rights in accordance with the terms hereof (including any cash paid pursuant to
Sections 2.02(c) or (e)) shall be deemed to have been issued and paid in full
satisfaction of all rights pertaining to such shares of Company Common Stock,
such Conversion-Merger Rights and such associated Rights.

          (e)  No Fractional Shares.  No fractional shares of Acquiror Common
               --------------------                                          
Stock shall be issued upon surrender for exchange of the Certificates, and any
such fractional share interests will not entitle the owner thereof to vote or to
any rights of a stockholder of Acquiror, but in lieu thereof each holder of
shares of Company Common Stock or Conversion-Merger Rights who would otherwise
be entitled to receive a fraction of a share of Acquiror Common Stock, after
aggregating all Certificates delivered by such holder, and rounding down to the
nearest whole

                                      -7-
<PAGE>
 
share, shall receive an amount in cash equal to the Average Trading Price (as
defined in Article X) on the Closing Date multiplied by the fraction of a share
of Acquiror Common Stock to which such holder would otherwise be entitled.  Such
payment in lieu of fractional shares shall be administered by the Exchange Agent
(in the case of Certificates representing Company Common Stock) or Acquiror (in
the case of Certificates representing Conversion-Merger Rights) pursuant to the
procedures set forth in Section 2.02(b).

          (f)  Termination of Exchange Fund.  Any portion of the Exchange Fund
               ----------------------------                                   
which remains undistributed to the holders of Company Common Stock for one (1)
year after the Effective Time shall be delivered to Acquiror, upon demand.  Any
holders of Company Common Stock who have not theretofore complied with this
Article II shall thereafter look only to Acquiror for the shares of Acquiror
Common Stock to which they are entitled pursuant to Section 2.01, any dividends
or other distributions with respect to Acquiror Common Stock to which they are
entitled pursuant to Section 2.02(c) and any cash in lieu of fractional shares
of Acquiror Common Stock to which they are entitled pursuant to Section 2.02(e).
Any shares of Acquiror Common Stock, any dividends or other distributions with
respect to Acquiror Common Stock, and any cash in lieu of fractional shares of
Acquiror Common Stock to which any holder of Company Common Stock or Conversion-
Merger Rights would otherwise be entitled pursuant to Section 2.01, Section
2.02(c) and Section 2.02(e), respectively, which remain unclaimed by such holder
on the fourth anniversary of the Effective Time (or such earlier date
immediately prior to such time as such property would otherwise escheat to or
become the property of any Governmental Entity (as defined in Article X)) shall,
to the extent permitted by Law, become the property of Acquiror free and clear
of any claims or interest of any Person (as defined in Article X) previously
entitled thereto.

          (g)  No Liability.  None of Acquiror, Acquiror Sub, the Company or the
               ------------                                                     
Exchange Agent shall be liable to any Person for any shares of Acquiror Common
Stock (or dividends or distributions with respect thereto) or cash delivered to
a public official pursuant to any abandoned property, escheat or similar Laws.

          (h)  Lost, Stolen or Destroyed Certificates or Instruments.  In the
               -----------------------------------------------------         
event any certificate evidencing shares of Company Common Stock and any
certificate or other instrument evidencing Conversion-Merger Rights (including
unexchanged Cooperative Interests) which immediately prior to the Effective Time
represented the right to receive shares of Company Common Stock shall have been
lost, stolen or destroyed, the Exchange Agent (in the case of Certificates
representing Company Common Stock) or Acquiror (in the case of Certificates
representing Conversion-Merger Rights) shall issue in exchange for such lost,
stolen or destroyed certificate or instrument, upon the making of an affidavit
of that fact by the holder thereof, such shares of Acquiror Common Stock and
cash, if any, as may be required pursuant to this Article II; provided, however,
                                                              --------  ------- 
that the Exchange Agent or Acquiror may, in its reasonable discretion and as a
condition precedent to 

                                      -8-
<PAGE>
 
the issuance thereof, require the owner of such lost, stolen or destroyed
certificate or instrument to deliver a bond in such sum as it may reasonably
direct as indemnity against any claim that may be made against Acquiror, the
Surviving Corporation, or the Exchange Agent with respect to the certificate or
instrument alleged to have been lost, stolen or destroyed.

     SECTION 2.03.  STOCK TRANSFER BOOKS.

     At the Effective Time, the stock transfer books of the Company shall be
closed and there shall be no further registration of transfers of shares of
Company Common Stock thereafter on the records of the Company.  From and after
the Effective Time, the holders of certificates representing shares of Company
Common Stock outstanding immediately prior to the Effective Time and the holders
of certificates or other instruments evidencing Conversion-Merger Rights
(including unexchanged Cooperative Interests) which immediately prior to the
Effective Time represented the right to receive shares of Company Common Stock
shall cease to have any rights with respect to such shares of Company Common
Stock and Conversion-Merger Rights except as otherwise provided herein or by
Law.  On or after the Effective Time, any Certificates presented to the Exchange
Agent or Acquiror for any reason shall be converted into the shares of Acquiror
Common Stock issuable in exchange therefor, any dividends or other distributions
to which the holders thereof are entitled pursuant to Section 2.02(c) and any
cash in lieu of fractional shares of Acquiror Common Stock to which the holders
thereof are entitled pursuant to Section 2.02(e).

     SECTION 2.04.  STOCK OPTIONS.

     Prior to the Effective Time, the Company and Acquiror shall take such
action as may be necessary or appropriate for Acquiror, at its option, to assume
or to issue a substitute option with respect to each outstanding unexpired and
unexercised option to purchase shares of Company Common Stock (collectively, the
"Company Stock Options") under the Company's 1997 Stock Incentive Plan (the
 ---------------------                                                     
"Company Stock Plan") or granted to certain officers independent of the Company
- -------------------                                                            
Stock Plan, so that at the Effective Time each Company Stock Option will become
or be replaced by an option to purchase a number of whole shares of Acquiror
Common Stock (an "Acquiror Option") equal to the number of shares of Company
                  ---------------                                           
Common Stock that could have been purchased (assuming full vesting) under the
Company Stock Option multiplied by the Exchange Ratio (and eliminating any
fractional share), at a price per share of Acquiror Common Stock equal to the
per-share option exercise price specified in the Company Stock Option.  Each
substituted Acquiror Option shall otherwise be subject to the same terms and
conditions as apply to the related Company Stock Option.  The date of grant of
each substituted Acquiror Option for purposes of such terms and conditions shall
be deemed to be the date on which the corresponding Company Stock Option was
granted.  As to each assumed Company

                                      -9-
<PAGE>
 
Stock Option, at the Effective Time (i) all references to the Company in the
stock option agreements with respect to the Company Stock Options being assumed
shall be deemed to refer to Acquiror; (ii) Acquiror shall assume all of the
Company's obligations with respect to the related Company Stock Option; and
(iii) Acquiror shall issue to each holder of a Company Stock Option a document
evidencing the foregoing assumption by Acquiror.  Nothing in this Section 2.04
shall affect the schedule of vesting with respect to the Company Stock Options
in accordance with the terms of such Company Stock Options, and Acquiror
acknowledges that the Company Stock Plan and the Company Stock Options granted
to Thomas W. Hertz and Craig A. Anderson independent of the Company Stock Plan
provide that such Company Stock Options will be 100% vested at the Effective
Time.  The Company represents and warrants that the assumption of Company Stock
Options or substitution of Acquiror Options therefor, as contemplated by this
Section 2.04, may be effected pursuant to the terms of the Company Stock
Options, the Company Stock Plan and the terms of the Company Stock Options
granted to certain officers of the Company independent of the Company Stock Plan
without the consent of any holder of a Company Stock Option and without
liability to any such holder.

     SECTION 2.05.  CLOSING.

     The parties agree that the Closing Event (as defined in Article X) will
take place at the offices of the Company in Irene, South Dakota on the Closing
Date (as defined in this Section 2.05).  Subject to the terms and conditions of
this Merger Agreement, the closing of the Merger (the "Closing") will take place
                                                       -------

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     Except as specifically set forth in the Disclosure Schedule delivered by
the Company to Acquiror prior to the execution and delivery of this Merger
Agreement (the "Company Disclosure Schedule") (with a disclosure with respect to
                ---------------------------                                     
a Section of this Merger Agreement to require a specific reference in the
Company Disclosure Schedule to the Section of this Merger Agreement to which
each such disclosure applies, and no disclosure to be deemed to apply with
respect to any Section to which it does not expressly refer), the Company hereby
represents and warrants (which representation and warranty shall be deemed to
include the disclosures with respect thereto so specified in the Company
Disclosure Schedule) to, and covenants and agrees with, Acquiror and Acquiror
Sub as follows, in each case as of the date of

                                      -10-

duly qualified to conduct business as a foreign corporation and is in good
standing in the states, countries and territories listed in Section 3.01 of the
Company Disclosure Schedule.  The Company is not qualified to conduct business
in any other jurisdiction, and neither the nature of the business conducted by
the Company nor the character of the Assets owned, leased or otherwise held by
it makes any such qualification necessary, except where the absence of such
qualification as a foreign corporation would not have a Company Material Adverse
Effect (as defined in Article X).  The Conversion-Merger and the other
transactions contemplated thereby were effected in compliance with all Laws.

     SECTION 3.02.  SUBSIDIARIES.

     Except as set forth in Section 3.02 of the Company Disclosure Schedule, the
Company has no Subsidiaries (as defined in Article X) and neither the Company
nor any Subsidiary has any equity investment or other interest in, nor has the
Company or any Subsidiary made advances or loans (other than for customary
credit extended to customers of the Company in the Ordinary Course of Business
(as defined in Article X) and reflected in the Financial Statements (as defined
in Section 3.08) or incurred in the Ordinary Course of Business since the date
of the latest Financial Statements, and other than transfers among the Company
and its wholly owned Subsidiaries) to, any corporation, association,
partnership, joint venture or other entity.  Section 3.02 of the Company
Disclosure Schedule sets forth (a) the authorized capital stock or other equity
interests of each direct and indirect Subsidiary of the Company and the
percentage of the outstanding capital stock or other equity interests of each
Subsidiary directly or indirectly owned by the Company, and (b) the nature and
amount as of October 22, 1998 of any such equity investment, other interest or
advance.  All of such shares of capital stock or other equity interests of
Subsidiaries directly or indirectly held by the Company have been duly
authorized and validly issued and are outstanding, fully paid and nonassessable.
The Company directly, or indirectly through wholly owned Subsidiaries, owns all
such shares of capital stock or other equity interests of the direct or indirect
Subsidiaries free and clear of all Encumbrances (as defined in Article X),
except as disclosed in Section 3.02 of the Company Disclosure Schedule.  Each
Subsidiary is a corporation duly organized, validly existing and in good

                                      -11-

standing under the Laws of its state or jurisdiction of incorporation (as listed
in Section 3.02 of the Company Disclosure Schedule), and has the full and
unrestricted corporate power and authority to own, operate and lease its Assets
and to carry on its business as currently conducted.  Each Subsidiary is duly
qualified to conduct business as a foreign corporation and is in good standing
in the states, countries and territories listed in Section 3.02 of the Company
Disclosure Schedule.  The Subsidiaries are not qualified to conduct business in
any other jurisdictions, and neither the nature of their businesses nor the

<PAGE>
 
Disclosure Schedule, all Company Licenses are valid and in full force and effect
through the respective dates indicated in the Company Disclosure Schedule,
except for any such invalidity or failure to be in full force and effect that
would not, alone or in the aggregate, have a Company Material Adverse Effect,
and no suspension, cancellation, complaint, proceeding, order or investigation
of or with respect to any such Company License (or operations thereunder) is

default under, nor has it breached, (i) any term or provision of its certificate
or articles of incorporation or bylaws or (ii) any Agreement or restriction to
which the Company or any Subsidiary is a party or by which the Company or any
Subsidiary, or any of their respective Assets, is bound or affected, except for
any such violation, default or breach described in clause (ii) that would not
have a Company Material Adverse Effect.  The Company and the Subsidiaries have
complied and are in full compliance with all Laws, except where the failure so
to comply would not have a Company Material Adverse Effect.  The Conversion-
Merger and the other transactions contemplated thereby were effected in
compliance with all Laws, neither the Company nor any Subsidiary has received
any notice, claim or allegation or has knowledge that the Conversion-Merger or
the other transactions contemplated thereby were not effected in compliance with

          (d)  Except as provided in Section 3.07(d) of the Company Disclosure
Schedule, neither the Company nor any Subsidiary has any interest in any License
(including both any Company License and any License held by third parties in
which the Company or any Subsidiary has an interest) material to the operation
of the Company or any Subsidiary that is subject to restrictions on assignment
or transfer based on the circumstances under which the License was granted (such
as eligibility or auction rules), the status of construction and operation (such
as rules restricting  resale for a certain period after construction), or any
other restrictions other than an ordinary course requirement for prior approval
of transactions such as the Merger contemplated herein.

          (e)  Neither the Company nor any Subsidiary is aware of any fact or
circumstance related to them that could reasonably be expected to cause the
filing of any objection to any application for any Governmental consent required
hereunder, lead to any delay in processing such application, or require any
waiver of any Governmental rule, policy or other applicable Law.

     SECTION 3.08.  SEC DOCUMENTS.

                                                     -----------------        
Company has furnished Acquiror with true and complete copies of each written
Company Contract (including any amendments thereto) and a complete written
summary of each oral Company Contract.

          (b)  Each Company Contract is in full force and effect and constitutes
a legal, valid and binding obligation of, and is legally enforceable against,
the respective parties thereto.  All necessary approvals of any Governmental
Entity with respect thereto have been obtained (except where the failure so to
obtain any such approval would not have a Company Material Adverse Effect), all
necessary filings or registrations therefor have been made, and there are no
outstanding disputes thereunder and, to the knowledge of the Company or any
Subsidiary, no threatened cancellation or termination thereof.  The Company and
the Subsidiaries have performed all material obligations thereunder required to
be performed by any of them to date.  To the knowledge of the Company and the
Subsidiaries, no party is in default in any material respect under any of the
Company Contracts, and there has not occurred any event which (whether with or
without notice, lapse of time or the happening or occurrence of any other event)
would constitute such a default.  No Agreement has been canceled or otherwise
terminated within the twelve (12) months prior to the date of this Merger
Agreement which would have been a "Company Contract" had such Agreement not been
canceled or terminated and the cancellation or termination of which has had or
is reasonably likely to have a Company Material Adverse Effect.  Except as
specifically described in Section 3.14(a) of the Company Disclosure Schedule,
there has been no written or oral modification or amendment to any Company
Contract and there are no reasonably expected changes to any Company Contract.
At the Closing, the Company shall deliver to Acquiror an updated Section 3.14(a)
to the Company Disclosure Schedule in accordance with the provisions of Section
6.05.

     SECTION 3.15.  LABOR RELATIONS.

          Section 3.15(a) of the Company Disclosure Schedule lists all
collective bargaining or other labor union Agreements to which the Company or
any Subsidiary is a party.  Except as set forth in Section 3.15(b) of the
Company Disclosure Schedule, there are no strikes, work stoppages, union
organization efforts or other controversies (other than grievance proceedings)
pending, threatened or reasonably anticipated between the Company or any
Subsidiary and (a) any current or former employees of the Company or of any
Subsidiary or (b) any union or other collective bargaining unit representing
such employees.  The Company and the Subsidiaries have complied and are in
compliance with all Laws relating to employment or the workplace, including,
without limitation, Laws relating to wages, hours, collective bargaining, safety
and health, work authorization, equal employment opportunity, immigration,
withholding, unemployment compensation, worker's compensation, employee privacy
and right to

                                      -23-

Adverse Effect.  Except as set forth in Section 3.15(c) of the Company
Disclosure Schedule, neither the Company nor any Subsidiary has been notified by
any Governmental Agency or counsel to any claimant of any unresolved violation
or alleged violation of any Law relating to equal employment opportunity, civil
or human rights, or employment discrimination generally.  Except as set forth in
Section 3.15(d) to the Company Disclosure Schedule, there are no collective
bargaining Agreements, employment Agreements between the Company or any
Subsidiary and any of their respective employees, or professional service
Agreements not terminable at will relating to the businesses and Assets of the
Company or of any Subsidiary.  Except as set forth in Section 3.15(e) to the
Company Disclosure Schedule, the consummation of the transactions contemplated
hereby will not cause Acquiror, the Surviving Corporation, the Company or any
Subsidiary to incur or suffer any liability relating to, or obligation to pay,
severance, termination or other payments to any Person.

     SECTION 3.16.  PENSION AND BENEFIT PLANS.

          (a)  Except as set forth in Section 3.16(a) to the Company Disclosure

terms of the Other Arrangement, all related trust Agreements or other funding
Documents (including, without limitation, insurance contracts, certificates of
deposit, money market accounts, etc.), all significant employee communications,
all correspondence with or other submissions to any

                                      -24-

Governmental Entity, and all current Agreements with service providers or
fiduciaries for providing services on behalf of any Other Arrangement.

          (c)  No Plan is a Multiemployer Plan (as defined in Article X).

          (d)  Section 3.16(d) of the Company Disclosure Schedule sets forth
each Individual Account Plan (as defined in Article X) that is an ESOP (as
defined in Article X) (indicating whether such ESOP is leveraged) or otherwise
invests in employer securities (as such term is defined in Section 409(l) of the
Code). The Company has furnished to Acquiror true and complete copies of all
loan Agreements and other related Documents for each leveraged ESOP.

          (e)  The funding method used under each Minimum-Funding Plan (as
defined in Article X) does not violate the funding requirements in Title I,
Subtitle B, Part 3, of ERISA (as defined in Article X).  For each Defined
Benefit Plan (as defined in Article X), the Company has furnished to Acquiror a
true and complete copy of the actuarial valuation reports issued by the
actuaries of that Defined Benefit Plan for the three (3) most recent plan years,
setting forth: (i) the actuarial present value (based upon the same actuarial
assumptions as were used for that period for funding purposes) of all vested and
nonvested accrued benefits under that Defined Benefit Plan; (ii) the actuarial
present value (based upon the same actuarial assumptions, other than turnover
assumptions, as were used for that period for funding purposes) of vested
benefits under that Defined Benefit Plan; (iii) the net fair market value of
that Defined Benefit Plan's Assets; and (iv) a detailed description of the
funding method used under that Defined Benefit Plan.

          (f)  No "accumulated funding deficiency" as defined in Section
302(a)(2) of ERISA or Section 412 of the Code, whether or not waived, and no
"unfunded current liability" as determined under Section 412(l) of the Code
exists with respect to any Minimum-Funding Plan.  No security is required under
Section 401(a)(29) of the Code as to any Minimum-Funding Plan.  Section 3.16(f)
of the Company Disclosure Schedule sets forth all unpaid obligations and
liabilities of the Company and the Subsidiaries to provide contributions
currently due with respect to any Minimum-Funding Plan.

          (g)  Section 3.16(g) of the Company Disclosure Schedule sets forth the
contributions that (i) the Company or any Subsidiary has promised or is
otherwise obligated to make under each Individual Account Plan that is a
Statutory-Waiver Plan (as defined in Article X) and (ii) are unpaid as of the
date of this Merger Agreement.

          (h)  The Company and the Subsidiaries have made all contributions and
other payments required by and due under the terms of each Plan and Other
Arrangement and have taken no action during the past three (3) years (other than
actions required by Law) relating to any Plan or Other Arrangement that will

                                      -25-
<PAGE>
 
increase Acquiror's, the Surviving Corporation's, the Company's or any
Subsidiary's obligation under any Plan or Other Arrangement.

          (i)  Section 3.16(i) of the Company Disclosure Schedule sets forth a
list of all Qualified Plans (as defined in Article X).  All Qualified Plans and
any related trust Agreements or annuity Agreements (or any other funding
Document) comply and have complied with ERISA, the Code (including, without
limitation, the requirements for Tax qualification described in Section 401
thereof), and all other Laws, except where the failure so to comply would not
have a Company Material Adverse Effect.  The trusts established under such Plans
are exempt from federal income taxes under Section 501(a) of the Code.  The
Company and the Subsidiaries have received determination letters issued by the
IRS with respect to each Qualified Plan, and the Company has furnished to
Acquiror true and complete copies of all such determination letters and all
correspondence relating to the applications therefor, or the remedial amendment
period under Section 401(b) of the Code has not elapsed with regard to the
initial adoption of such Qualified Plan.  All statements made by or on behalf of
the Company or any Subsidiary to the IRS in connection with applications for
determinations with respect to each Qualified Plan were true and complete when
made and continue to be true and complete.  To the knowledge of the Company and
the Subsidiaries, nothing has occurred since the date of the most recent
applicable determination letter that would adversely affect the tax-qualified
status of any Qualified Plan.

          (j)  To their knowledge, the Company and the Subsidiaries have
complied in all material respects with all applicable provisions of the Code,
ERISA, the National Labor Relations Act, Title VII of the Civil Rights Act of
1964, the Age Discrimination in Employment Act, the Fair Labor Standards Act,
the Securities Act, the Exchange Act, and all other Laws pertaining to the
Plans, Other Arrangements and other employee or employment related benefits, and
all premiums and assessments relating to all Plans or Other Arrangements.
Neither the Company nor any Subsidiary has any liability for any delinquent
contributions within the meaning of Section 515 of ERISA (including, without
limitation, related attorneys' fees, costs, liquidated damages and interest) or
for any arrearages of wages. Neither the Company nor any Subsidiary has any
pending unfair labor practice charges, contract grievances under any collective
bargaining agreement, other administrative charges, claims, grievances or
lawsuits before any court, arbiter or Governmental Entity arising under any Law
governing any Plan, and to the knowledge of the Company and the Subsidiaries
there exist no facts that could give rise to such a claim.

          (k)  Section 3.16(k) of the Company Disclosure Schedule describes all
transactions in which, to the knowledge of the Company and the Subsidiaries, the
Company or any Subsidiary or any of the Plans has engaged in violation of
Section 406(a) or 406(b) of ERISA for which no exemption exists under Section
408 of ERISA and all "prohibited transactions" (as such term is defined in

                                      -26-
<PAGE>
 
Section 4975(c)(1) of the Code), for which no exemption exists under Section
4975(c)(2) or 4975(d) of the Code. The Company has furnished to Acquiror true
and complete copies of each request for a prohibited transaction exemption and
each exemption obtained in response to such request. All such requests were true
and complete when made and continue to be true and complete.

          (l)  The Company and the Subsidiaries have paid all premiums (and
interest charges and penalties for late payment, if applicable) due to the PBGC
for each Defined Benefit Plan.  The Company has reflected (or shall reflect) in
the Financial Statements the current value of such premium obligation that is
accrued and unsatisfied as of the date of each such Financial Statement.
Section 3.16(l) of the Company Disclosure Schedule sets forth the amount of all
such unpaid premium obligations (including, without limitation, proportionate
partial accruals for the current year).  Other than being required to make and
making premium payments when due, no liability to the PBGC has been incurred by
the Company or by any Common Control Entity (as defined in Article X) on account
of Title IV of ERISA.  During the past three (3) years, no filing has been made
by, or required of, the Company or any Common Control Entity with the PBGC, the
PBGC has not started any proceeding to terminate any Defined Benefit Plan that
was or is maintained or wholly or partially funded by the Company or any Common
Control Entity, and to the knowledge of the Company and the Subsidiaries, no
facts exist that would permit the PBGC to begin such a proceeding.  Neither the
Company nor any Common Control Entity has, or will have as a result of the
transactions contemplated hereby, (i) withdrawn as a substantial employer so as
to become subject to Section 4063 of ERISA; or (ii) ceased making contributions
to any Pension Plan that is subject to Section 4064(a) of ERISA to which the
Company or any Common Control Entity made contributions during the past five (5)
years.

          (m)  Section 3.16(m) of the Company Disclosure Schedule identifies any
terminated Plan that covered any current or former employees of the Company or
any Subsidiary, and any other Plan that has been terminated, during the past
three (3) years.  The Company has furnished to Acquiror true and complete copies
of all filings with any Governmental Entity, employee communications, board
minutes and all other Documents relating to each such termination of a Qualified
Plan.

          (n)  Except as set forth in Section 3.16(n) of the Company Disclosure
Schedule, no Plan or Other Arrangement, individually or collectively, provides
for any payment by the Company or any Subsidiary to any employee or independent
contractor that is not deductible under Section 162(a)(1) or 404 of the Code or
that is an "excess parachute payment" pursuant to Section 280G of the Code.

          (o)  No Plan has within the past three (3) years experienced a
"reportable event" (as such term is defined in Section 4043(b) of ERISA) that is
not subject to an administrative or statutory waiver from the reporting
requirement.

                                      -27-
<PAGE>
 
          (p)  No Plan is a "qualified foreign plan" (as such term is defined in
Section 404A(e) of the Code), and no Plan is subject to the Laws of any
jurisdiction other than the United States of America or one of its political
subdivisions.

          (q)  The Company and the Subsidiaries have timely filed and the
Company has furnished to Acquiror true and complete copies of each Form 5330
(Return of Excise Taxes Related to Employee Benefit Plans) that the Company or
any Subsidiary filed on any Plan during the past three (3) years. To their
knowledge, the Company and the Subsidiaries have no liability for Taxes required
to be reported on Form 5330.

          (r)  Section 3.16(r) of the Company Disclosure Schedule lists all
funded Welfare Plans (as defined in Article X) that provide benefits to current
or former employees of the Company or any Subsidiary, or to their beneficiaries.
The funding under each Welfare Plan does not exceed and has not exceeded the
limitations under Sections 419A(b) and 419A(c) of the Code.  To their knowledge,
the Company and the Subsidiaries are not subject to taxation on the income of
any Welfare Plan's welfare benefit fund (as such term is defined in Section
419(e) of the Code) under Section 419A(g) of the Code.

          (s)  Section 3.16(s) of the Company Disclosure Schedule (i) identifies
all post-retirement medical, life insurance or other benefits promised, provided
or otherwise due now or in the future to current, former or retired employees of
the Company or any Subsidiary, (ii) identifies the method of funding (including,
without limitation, any individual accounting) for all such benefits, (iii)
discloses the funded status of the Plans providing or promising such benefits,
and (iv) sets forth the method of accounting for such benefits to any key
employees (as defined in Section 416(i) of the Code) of the Company or any
Subsidiary.

          (t)  All Welfare Plans and the related trusts that are subject to
Section 4980B(f) of the Code and Sections 601 through 607 of ERISA comply in all
material respects with and have been administered in all material respects in
compliance with the health care continuation-coverage requirements for tax-
favored status under Section 4980B(f) of the Code (formerly Section 162(k) of
the Code), Sections 601 through 607 of ERISA, and all proposed or final
regulations under Section 162 of the Code explaining those requirements.

          (u)  The Company and the Subsidiaries have (i) filed or caused to be
filed all returns and reports on the Plans that they are required to file, and
(ii) paid or made adequate provision for all fees, interest, penalties,
assessments or deficiencies that have become due pursuant to those returns or
reports or pursuant to any assessment or adjustment that has been made relating
to those returns or reports. All other fees, interest, penalties and assessments
that are due and payable by or for the Company or any Subsidiary with respect to
any Plan have been timely reported, fully paid and discharged. There are no
unpaid fees,

                                      -28-
<PAGE>
 
penalties, interest or assessments due from the Company or any Subsidiary or
from any other Person that are or could become an Encumbrance on any Asset of
the Company or any Subsidiary or could otherwise have a Company Material Adverse
Effect. The Company and the Subsidiaries have collected or withheld all amounts
that are required to be collected or withheld by them to discharge their
obligations with respect to each Plan, and all of those amounts have been paid
to the appropriate Governmental Entity or set aside in appropriate accounts for
future payment when due.

payment of all unpaid Taxes, whether or not such Taxes are disputed or are yet
due and payable, for or with respect to the applicable period, and for which the
Company or any Subsidiary may be liable in its own right (including, without
limitation, by reason of being a member of the same affiliated group) or as a
transferee of the Assets of, or successor to, any Person.

          (b)  Neither the Company nor any Subsidiary, either in its own right
(including, without limitation, by reason of being a member of the same

Company or any Subsidiary, threatened.  Except as set forth in Section 3.17(c)

software; (ii) Multiview accounting software; (iii) Lucent switching, access and
SONET systems; (iv) ILS software; (v) Bay, Cisco and Livingston routers used by

extent that the Surviving Corporation would be permitted by applicable Law (and

permitted under applicable Law), each such Manager against any losses, claims,
damages, liabilities, costs, expenses (including reasonable attorneys' fees),
judgments, fines and amounts paid in settlement in connection with any such
claim, action, suit, proceeding or investigation; and in the event of any such

without its prior written consent (which consent shall not be unreasonably
withheld); and provided further that the Company's, the Surviving Corporation's
               -------- -------

Board of Directors of
 Dakota Telecommunications Group, Inc.
29705 453rd Avenue
Irene, South Dakota 57037-0066

Gentlemen:

Duff & Phelps, LLC ("Duff & Phelps") has been engaged by the board of directors
("Board") of Dakota Telecommunications Group, Inc. ("DTG" or the "Company") as
financial advisor.  Specifically, Duff & Phelps has been engaged to determine if
a Proposed Transaction (as defined below) is fair to the shareholders of DTG
from a financial point of view.

The Company is a facilities-oriented telecommunications firm that offers local
and long-distance telephone services, cable services, internet services and
network consulting services.  It is our understanding that DTG is considering a
transaction (the "Proposed Transaction") wherein the Company would be acquired
by McLeodUSA Incorporated ("McLeod"), and each share of common stock of DTG
would be exchanged for 0.4328 shares of McLeod common stock.  McLeod is a
provider of integrated telecommunications services in Midwest and Rocky Mountain
states with common stock that is publicly traded on the NASDAQ National Market
System.  We understand that the Proposed Transaction will be submitted to the
shareholders of DTG for approval at a Special Meeting of the Shareholders.

For purposes of our opinion and in connection with our review of the Proposed
Transaction, we have, among other things:

1.   Reviewed a draft dated as of October 22, 1998 of an Agreement and Plan of
     Merger by and among McLeodUSA Incorporated, West Group Acquisition Co. and
     Dakota Telecommunications Group, Inc., including drafts of exhibits and
     schedules thereto;

2.   discussed the history, current operations and future outlook of DTG as well
     as the history and terms of the Proposed Transaction with Company
     management;

3.   reviewed the Company's Form 10-KSB for the year ended December 31, 1997;

4.   reviewed the Company's Form 10-QSB for the period ended June 30, 1998;

5.   reviewed the DTG CLEC Facilities Expansion Plan dated as of July 1998;

6.   reviewed a Private Placement Memorandum dated as of May 1998 prepared in
     conjunction with the firm of Houlihan Lokey Howard & Zukin ("HLHZ");

7.   reviewed a 1998--2002 Development Forecast dated as of May 1998;

8.   reviewed the market prices and trading activity of the common stock of
     McLeod;

10.  reviewed the McLeod Form 10-Q for the period ended June 30, 1998; and

11.  performed such other review and analyses as we deemed necessary.

Our opinion is based upon an analysis of the foregoing in light of our
assessment of general economic and financial market conditions as they can be
evaluated by us as of the date hereof.  As of the time of the completion of our
analysis, the common stock of McLeod was trading in a range of approximately $32
to $35 per share.

In connection with our opinion, with your permission and without any independent
verification, we have relied on the accuracy and completeness of all the
financial and other information reviewed by us, furnished, or otherwise
communicated to us by the Company or obtained by us from publicly available
sources. We have not made an independent valuation or appraisal of the assets or
liabilities of the Company and have not been furnished with such valuation or
appraisal.  Any inaccuracies in the information on which we relied could
materially affect our opinion.  Duff & Phelps has previously served as financial
advisor to the employee stock ownership plan of the Company.

          In rendering this opinion, we have assumed that the Proposed
Transaction occurs on terms that are described in the Merger Agreement.
Nonetheless, it should be recognized that we are not making any recommendation
as to whether the shareholders of the Company should vote in favor of the
Proposed Transaction.

Based upon the foregoing, it is our opinion that the Proposed Transaction is
fair to the shareholders of Dakota Telecommunications Group, Inc. from a
financial point of view.

                              Respectfully submitted,

Item 20. Indemnification of Directors and Officers

  Under Section 145 of the Delaware General Corporation Law ("DGCL"), a
corporation may indemnify its directors, officers, employees and agents and its
former directors, officers, employees and agents and those who serve, at the
corporation's request, in such capacities with another enterprise, against
expenses (including attorneys' fees), as well as judgments, fines and
settlements in nonderivative lawsuits, actually and reasonably incurred in
connection with the defense of any action, suit or proceeding in which they or
any of them were or are made parties or are threatened to be made parties by
reason of their serving or having served in such capacity. The DGCL provides,
however, that such person must have acted in good faith and in a manner such
person reasonably believed to be in (or not opposed to) the best interests of
the corporation and, in the case of a criminal action, such person must have had
no reasonable cause to believe his or her conduct was unlawful. In addition, the
DGCL does not permit indemnification in an action or suit by or in the right of
the corporation, where such person has been adjudged liable to the corporation,
unless, and only to the extent that, a court determines that such person fairly
and reasonably is entitled to indemnity for costs the court deems proper in
light of liability adjudication. Indemnity is mandatory to the extent a claim,
issue or matter has been successfully defended.

  The Amended and Restated Certificate of Incorporation of McLeodUSA (the
"McLeodUSA Certificate") contains provisions that provide that no director of
McLeodUSA shall be liable for breach of fiduciary duty as a director except for
(1) any breach of the directors' duty of loyalty to McLeodUSA or its
stockholders; (2) acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of the law; (3) liability under
Section 174 of the DGCL; or (4) any transaction from which the director derived
an improper personal benefit. The McLeodUSA Certificate contains provisions that
further provide for the indemnification of directors and officers to the fullest
extent permitted by the DGCL. Under the Bylaws of McLeodUSA, McLeodUSA is
required to advance expenses incurred by an officer or director in defending any
such action if the director or officer undertakes to repay such amount if it is
determined that the director or officer is not entitled to indemnification. In
addition, McLeodUSA has entered into indemnity agreements with each of its
directors pursuant to which McLeodUSA has agreed to indemnify the directors as
permitted by the DGCL. McLeodUSA has obtained directors and officers liability
insurance against certain liabilities, including liabilities under the
Securities Act.

ITEM 22.UNDERTAKINGS

  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

  The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of this Registration Statement through
the date of responding to the request.

  The undersigned registrant hereby undertakes to supply by means of a post-
effective amendment all information concerning a transaction, and the company
being acquired involved therein, that was not the subject of and included in
this Registration Statement when it became effective.
<PAGE>
 
  The undersigned registrant hereby undertakes to file, during any period in
which offers or sales are being made, a post-effective amendment to this
Registration Statement;

     (i)   to include any prospectus required by Section 10(a)(3) of the
  Securities Act of 1933 (the "Securities Act");

     (ii)  to reflect in the prospectus any facts or events arising after the
  effective date of this Registration Statement (or the most recent post-
  effective amendment hereof) which, individually or in the aggregate,
  represents a fundamental change in the information set forth in this
  Registration Statement. Notwithstanding the foregoing, any increase or
  decrease in volume of securities offered (if the total dollar value of
  securities offered would not exceed that which was registered) and any
  deviation from the low or high end of the estimated maximum offering range may
  be reflected in the form of prospectus filed with the Securities and Exchange
  Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume
  and price represent no more than a 20% change in the maximum aggregate
  offering price set forth in the "Calculation of Registration Fee" table in
  this Registration Statement when it becomes effective; and

     (iii) to include any material information with respect to the plan of
  distribution not previously disclosed in this Registration Statement or any
  material change to such information in this Registration Statement.

  The undersigned registrant hereby undertakes that, for the purpose of
determining any liability under the Securities Act, each such post-effective
amendment shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.

  The undersigned registrant hereby undertakes to remove from registration by
means of a post-effective amendment any of the securities being registered which
remain unsold at the termination of the offering.

  The undersigned registrant hereby undertakes that, for purposes of determining
any liability under the Securities Act, each filing of the registrant's annual
report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

  The undersigned registrant hereby undertakes as follows:  that prior to any
public reoffering of the securities registered hereunder through the use of a
prospectus which is a part of this Registration Statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by Form S-4 with respect to reofferings by persons who may be deemed
underwriters, in addition to the information called for by the other items of
Form S-4.
<PAGE>
 
  The undersigned registrant hereby undertakes that every prospectus (i) that is
filed pursuant to the immediately preceding paragraph, or (ii) that purports to
meet the requirements of Section 10(a)(3) of the Act and is used in connection
with an offering of securities subject to Rule 415, will be filed as a part of
an amendment to the Registration Statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

Ladies and Gentlemen:

          We are acting as special counsel to MeLeodUSA Incorporated, a Delaware
corporation (the "COMPANY"), in connection with its registration statement on 
Form S-4 (the "REGISTRATION STATEMENT") filed with the Securities and Exchange 
Commission relating to the proposed offering of up to 1,295,000 shares (the 
"SHARES") of the Company's Class A common stock, par value $.01 per share (the 
"MCLEODUSA CLASS A COMMON STOCK"), to shareholders of Dakota Telecommunications 
Group, Inc., a Delaware corporation ("DTG"). The Shares are being offered in 
connection with that certain merger (the "MERGER") of West Group Acquisition 
Co., a newly formed Delaware corporation and wholly owned subsidiary of the 
Company ("MERGER SUB"), with and into DTG, as contemplated by the terms of that 
certain Agreement and Plan of Merger among the Company, Merger Sub and DTG dated
as of October 27, 1998 (the "MERGER AGREEMENT"). This opinion letter is 
furnished to you at your request to enable you to fulfill the requirements of 
Item 601(b)(5) of Regulation S-K, 17 C.F.R (S) 229.601(b)(5), in connection with
the Registration Statement.

          For purposes of this opinion letter, we have examined copies of the 
following documents:

          1.   An executed copy of the Registration Statement.

          2.   The Amended and Restated Certificate of Incorporation of the
               Company, as certified by the Secretary of State of the State of
               Delaware on October 22, 1998 and by the Secretary of the Company
               on the date hereof as then being complete, accurate and in
               effect.

          3.   The Amended and Restated Bylaws of the Company, as certified by
               the Secretary of the Company on the date hereof as then being
               complete, accurate and in effect.

          4.   An executed copy of the Merger Agreement.

          5.   Resolutions of the Board of Directors of the Company adopted on
               October 22, 1998, as certified by the Secretary of the Company on
               the
<PAGE>
 
               date hereof as then being complete, accurate and in effect,
               relating to the issuance of the Shares and arrangements in
               connection therewith.

          In our examination of the aforesaid documents, we have assumed the 
genuineness of all signatures, the legal capacity of natural persons, the 
authenticity, accuracy and completeness of all documents submitted to us, and 
the conformity with the original documents of all documents submitted to us as 
certified, telecopied, photostatic, or reproduced copies. This opinion letter is
given, and all statements herein are made, in the context of the foregoing.

          This opinion letter is based as to matters of law solely on the 
General Corporation Law of the State of Delaware. We express no opinion herein 
as to any other laws, statutes, regulations, or ordinances.

          Based upon, subject to and limited by the foregoing, we are of the 
opinion that following (i) effectiveness of the Registration Statement, (ii) the
consummation of the Merger and the issuance of the Shares pursuant to the terms 
of the Merger Agreement and (iii) receipt by the Company of the consideration 
for the Shares specified in the resolutions of the Board of Directors, the 
Shares will be validly issued, fully paid and nonassessable under the General 
Corporation Law of the State of Delaware.

          We assume no obligation to advise you of any changes in the foregoing 
subsequent to the delivery of this opinion letter. This opinion letter has been 
prepared solely for your use in connection with the filing of the Registration

                               December 11, 1998


Dakota Telecommunications Group, Inc.
Post Office Box 66
29705 453rd Avenue
Irene, South Dakota 57037-0066

     You have requested our opinion regarding the federal income tax
consequences of the proposed affiliation of Dakota Telecommunications Group,
Inc., a Delaware corporation (the "Company"), with McLeodUSA Incorporated, a
Delaware corporation ("Acquiror"), through the proposed merger (the "Merger") of
West Group Acquisition Co., a Delaware corporation ("Acquiror Sub"), a wholly
owned subsidiary of Acquiror, with and into the Company under the terms of an
Agreement and Plan of Merger dated as of October 27, 1998 (the "Merger
Agreement") among the Company, Acquiror and Acquiror Sub.  Capitalized terms not
defined herein shall have the meanings ascribed to them in the Merger Agreement.

     Pursuant to the Merger Agreement, Acquiror has formed Acquiror Sub as a
wholly owned subsidiary for the sole purpose of the Merger.  Acquiror Sub will
be merged with and into the Company under the General Corporation Law of the
State of Delaware and in accordance with the Merger Agreement. In the Merger,
all of the issued and outstanding shares common stock of the Company (the
"Company Stock") will be converted into shares of Acquiror common stock (the
"Acquiror Stock"), and the surviving corporation will become a wholly owned
subsidiary of Acquiror.

     This opinion is based upon facts regarding the Merger as described in the
Merger Agreement and the Registration Statement on Form S-4 filed with the
Securities and Exchange Commission, and the following assumptions:

     1.  The Merger will be consummated in strict accordance with the Merger
Agreement and applicable state law and will qualify as a statutory merger under
the General Corporation Law of the State of Delaware.

     2.  The information contained Registration Statement and the Merger
Agreement accurately and completely describe all material facts concerning the
transaction that are relevant to our opinion.

     3.  The parties' principal reasons for participating in the Merger are bona
fide business reasons and not tax reasons.

     4.  As of the Effective Time, the fair market value of the Acquiror Stock
received by each holder of Company Stock will be approximately equal to the fair
market value of the Company Stock surrendered in the Merger.

     5.  Following the Effective Time, the Company will not issue additional
shares of its stock (or securities, options, warrants or instruments giving the
holder thereof the right to acquire Company stock) or take any other action that
would result in Acquiror losing control of the Company within the meaning of
Section 368(c) of the Internal Revenue Code of 1986, as amended (the "Code").
At the Effective Time, the Company will not have outstanding any warrants,
options, convertible securities, or any other type of right pursuant to which
any person could acquire stock in the Company that, if exercised or converted,
would affect Acquiror's acquisition or retention of control of the Company, as
defined in Section 368(c) of the Code.

     6.  Following the Effective Time, the Company will hold at least ninety
percent of the fair market value of its net assets and at least seventy percent
of the fair market value of its gross assets and at least ninety percent of the
fair market value of Acquiror Sub's net assets and at least seventy percent of
the fair market value of Acquiror Sub's gross assets held immediately prior to
the Merger.  For purposes of this representation, amounts used by the Company or
Acquiror Sub to pay reorganization expenses and all redemptions and
distributions (except for regular, normal dividends) made by the Company will be
included as assets of the Company or Acquiror Sub, respectively, immediately
prior to the Merger.

     7.  Since January 1, 1998, the Company has not redeemed any Company Stock
nor made any distributions to its stockholders.  Other than acquisitions of
Company Stock by Acquiror in the Merger, no person related to the Company
(within the meaning of Treas. Reg. 1.368-1(e)(3)) has or will acquire Company
Stock from any stockholder.

     8.  Following the Merger, the Company will continue its historic business
or use a significant portion of its historic business assets in a business.

     9.  Acquiror has no present and as of the Effective Time will have no plan
or intention to reacquire any of the Acquiror Stock issued in the Merger.

     10. The liabilities of the Company were and as of the Effective Time will
have been incurred by the Company in the ordinary course of business.

Dakota Telecommunications Group Inc.

     11.  The Company and its stockholders, Acquiror and Acquiror Sub will each
pay their respective expenses, if any, incurred in connection with the Merger.

     12.  Except for cash paid in lieu of fractional shares, Acquiror will
acquire all of the Company Stock solely in exchange for voting stock of
Acquiror, and the amount of Company Stock so acquired will constitute control of
the Company within the meaning of Section 368(c) of the Code.

     13.  Neither the Company, Acquiror nor Acquiror Sub is and as of the
Effective Time none will be an investment company as defined in Section
368(a)(2)(F)(iii) and (iv) of the Code.

     14.  At the Effective Time, the fair market value of the assets of the
Company will equal or exceed the sum of its liabilities, plus the amount of
liabilities, if any, to which the Company's assets are subject.

     15.  Neither Acquiror nor any affiliate of Acquiror owns, directly or
indirectly, nor has Acquiror or any affiliate of Acquiror owned during the past
five years, any shares of the capital stock of the Company.

     16.  Acquiror has no present and as of the Effective Time will have no plan
or intention to liquidate the Company; to merge the Company with or into another
corporation; to sell or otherwise dispose of the Company Stock or to cause the
Company to sell or otherwise dispose of any of its assets or of any of its
assets acquired from Acquiror Sub, except for dispositions made in the ordinary
course of business or transfers described in Treas. Reg. 1.368-2(k)(2).

     17.  The Company is not and at the Effective Time will not be under the
jurisdiction of a court in a Title 11 or a similar case within the meaning of
Section 368(a)(3)(A) of the Code.

     18.  There is no and as of the Effective Time will not be any
intercorporate indebtedness existing between Acquiror and the Company or between
Acquiror Sub and the Company that was issued, acquired, or will be settled at a
discount.

     19.  The payment of cash in lieu of fractional shares of Acquiror Stock is
solely for the purpose of avoiding the expense and inconvenience to Acquiror of
issuing fractional shares and does not represent separately bargained for
consideration.  The fractional share interests of each Company stockholder will
be aggregated and no Company stockholder will receive cash in lieu of fractional
shares in an amount equal to or greater than the value of one full share of
Acquiror Stock.

     20.  None of the compensation received by any stockholder-employees of the
Company will be separate consideration for or allocable to, any of their shares
of Company Stock, none of the shares of Acquiror Stock received by any
stockholder-employees of Company will be separate consideration for, or
allocable to, any employment agreement or covenant not to compete; and the
compensation paid to any stockholder-employee will be for services actually
rendered and will be commensurate with amounts paid to third parties bargaining
at arms length for similar services.

     Based on the facts and assumptions set forth above, and subject to the
limitations and conditions identified in this opinion, it is our opinion that
the Merger of Acquiror Sub with and into the Company would give rise to the
following federal income tax consequences under the Code:

     1.   The Merger of Acquiror Sub with and into the Company will constitute a
reorganization under Section 368(a) of the Code and the Company will be "a party
to a reorganization" within the meaning of Section 368(b) of the Code.

     2.   The Company will not recognize any gain or loss for United States
federal income tax purposes as a result of the Merger.

     3.   No gain or loss will be recognized by the stockholders of the Company
who receive shares of Acquiror Stock in exchange for all of their shares of
Company Stock, except to the extent of any cash received in lieu of a fractional
share of Acquiror Stock.

     4.   The basis of Acquiror Stock to be received by the stockholders of the
Company will, in each instance, be the same as the basis of the respective
shares of Company Stock surrendered in exchange therefor.
<PAGE>
 
Dakota Telecommunications Group Inc.
December 11, 1998

     5.   The holding period of the Acquiror Stock received by the stockholders
of the Company will, in each instance, include the holding period of the
respective shares of Company Stock surrendered in exchange therefor; provided,
that the Company Stock was, in each instance, held as a capital asset in the
hands of the stockholder at the Effective Time.

     We express no opinion about the tax treatment of the Merger under other
provisions of the Code and regulations, of any conditions existing at the time
of, or the effects resulting from, the Merger that are not specifically covered
above, under foreign, state, or local laws, or under estate or gift tax
statutes.  The particular circumstances of a stockholder of the Company may
cause the stockholder's tax consequences to differ from those described in this
opinion, including, but not limited to, stockholders of the Company who are
corporations, trusts, dealers in securities, financial institutions, insurance
companies, tax exempt organizations, persons who are not United States citizens
or resident aliens or domestic corporations, who acquired Company Stock pursuant
to employee stock options or otherwise as compensation, who do not hold their
shares as capital assets, who are subject to the alternative minimum tax (to the
extent that tax affects the tax consequences), who are subject to the "golden
parachute" provisions of the Code (to the extent that tax affects the tax
consequences), or who hold their shares as part of a "straddle" or "conversion
transaction."

     This opinion represents our best legal judgment, but it has no binding
effect or official status of any kind, and no assurance can be given that
contrary positions may not be taken by the Internal Revenue Service or a court
considering the issues.  Future changes in federal income tax laws and the
interpretation of the federal income tax laws can have retroactive effect.

     This opinion has been requested and is provided solely for the purpose of
inclusion as an exhibit to the Form S-4 Registration Statement filed by Parent
with the Securities and Exchange Commission in connection with the proposed
Merger.   If the Merger occurs, it will occur at a date significantly later than
the date of this opinion.  Applicable law, regulations, judicial
interpretations, regulatory positions, and known facts are all subject to
change.   This opinion is based only upon such law, regulations,
interpretations, positions, and facts as are now in existence and known to us as
of the date of this opinion and assumes no change between the date of this
opinion and the date of the Merger.   For this reason, this opinion is not
intended, and may not be relied upon, to satisfy the condition precedent to the
Merger stated in Section 7.03(f) of the Merger Agreement.
