                      IV. CONTEMPLATED FUTURE TRANSACTION

     4.01  Intentions. NETCO and WCOM intend to provide, in accordance with the
           ----------
terms of this Agreement, for the liquidity of investment by minority
shareholders of NETCO and by others who hold interests exercisable or
convertible into shares of NETCO's common Stock. In view of that intention,
NETCO and WCOM desire to provide alternatives that will allow, in light of
future

                                       3

 
circumstances as they may now be foreseen, for the liquidity of investment by
such minority interest holders of NETCO. Provided, however, nothing herein
contained shall be deemed to create any obligation by WCOM to purchase any
securities, rights or interests of any kind in NETCO, or to assure a market or
value thereafter, except as may be expressly stated herein.

     4.02  Tender or Buy-Back. (a) Unless NETCO shall be a publicly held company
           ------------------
then required to file periodic reports under Section 13(a) or 15(d) of the
Securities Exchange Act of 1934 with its Common Stock listed for trading on the
NASDAQ Small Cap Market, the NASDAQ Stock Market or on a national securities
exchange, then, during calendar year 2000, WCOM, in accordance with the
provisions of this Section 4.02, shall either (i) tender for the purchase of all
outstanding shares of NETCO Common Stock and all outstanding options, warrants,
convertible securities and other rights or interests to purchase shares of NETCO
Common Stock, or (ii) sell to NETCO the Common Stock Purchase Warrants and/or
the shares acquired upon exercise thereof or upon conversion of the Convertible
Note as may be then owned by WCOM.

     (b)   NETCO's management and Board of Directors shall obtain during
calendar year 2000 from a nationally recognized investment banking firm a
valuation of the fair market value per share of NETCO's Common Stock without a
premium allocated for any controlling ownership of NETCO. Provided, however, if
such valuation has not been obtained by NETCO's management and Board of
Directors by June 30, 2000, holders of at least Eight Hundred Thousand (800,000)
shares of NETCO's Common Stock may apply jointly to the Chief Judge of the
Hennepin County District Court, Hennepin County Minnesota, for appointment of a
nationally recognized investment banking firm to promptly determine and report
such valuation, and all fees, costs and expenses incurred in connection with
such application, including fees and expenses of counsel chosen by such
shareholders to make the application and the fees and expenses of the investment
banking firm chosen by the Court, shall be borne by NETCO. The Court shall
retain jurisdiction until such valuation shall have been reported, and the Court
shall be empowered to order any party to this Agreement, its officers, agents
and employees to furnish any information necessary to establish and report such
valuation. For purposes hereof, the valuation established pursuant to this
Section 4.02(b) shall be referred to as the "Tender Valuation."

     (c)   Upon receipt of the Tender Valuation, WCOM may tender (the "First
Tender") to purchase (i) all outstanding shares of Common Stock of NETCO and
(ii) all outstanding options, warrants, convertible securities and other rights
or interests to purchase shares of NETCO Common Stock held by persons other than
WCOM or any of its affiliates (excluding only such affiliates of WCOM whose
affiliation with WCOM arise solely from their affiliation with NETCO). The First
Tender may be in the form of cash, unrestricted WCOM common stock issued
pursuant to an effective registration statement under the Securities Act of
1933, or a combination thereof. The First Tender for each share of Common Stock
shall be at a price at least equal to

                                       4

 
the per share valuation obtained pursuant to Section 4.02(b) hereof; and the
First Tender for all other rights or interests to purchase NETCO Common Stock
shall be the same price offered for each share of NETCO Common Stock less the
amount payable pursuant to such right or interest to purchase a share of NETCO
Common Stock. The First Tender shall remain open for acceptance for at least
thirty (30) days but not longer than sixty (60) days. For purposes hereof,
"affiliate" shall have the meaning ascribed in Rule 12b-2 of the General Rules
and Regulations under the Securities Exchange Act of 1934.

     (d)   WCOM shall sell, and NETCO shall purchase for the price ("NETCO
Purchase Price") specified below, the Common Stock Purchase Warrants and/or
shares of Common Stock theretofore issued to WCOM upon exercise thereof or upon
conversion of the Convertible Note upon occurrence of the following
circumstances:

     (i)       WCOM fails to make the First Tender within ninety (90) days
               following receipt of the Tender Valuation provided in section
               4.02(b) hereof; or

     (ii)      owners of a majority of the then outstanding shares of NETCO
               Common Stock (excluding shares which may be owned by WCOM or its
               affiliates) reject WCOM's First Tender, and WCOM makes no Second
               Tender as provided hereinafter; or

     (iii)     owners of a majority of the then outstanding shares of NETCO
               Common Stock (excluding shares which may be owned by WCOM or its
               affiliates) reject WCOM's Second Tender as provided hereinafter.

In the event owners of a majority of the then outstanding shares of NETCO
(excluding shares which may be owned by WCOM and its affiliates) reject WCOM's
First Tender, WCOM shall have sixty (60) days following such rejection to again
tender (the "Second Tender") to purchase the same outstanding shares, options,
warrants, convertible securities and other rights or interests to acquire NETCO
shares. During such sixty (60) day period, NETCO shall make a good faith effort
to determine what price might be acceptable to the owners of such shares, and
shall communicate such information to WCOM. The Second Tender may be in the form
of cash, unrestricted WCOM common stock issued pursuant to an effective
registration statement under the Securities Act of 1933, or a combination
thereof. The Second Tender for each share of Common Stock shall be at a price
per share determined by WCOM; and the Second Tender for all other rights or
interests to purchase NETCO Common Stock shall be the same price offered for
each share of NETCO Common Stock less the amount payable pursuant to such right
or interest to purchase a share of NETCO Common Stock. The Second Tender shall
remain open for acceptance for at least thirty (30) days but not longer than
sixty (60) days.

                                       5

 
     (e)   The purchase price payable by NETCO for all shares of the Common
Stock theretofore purchased by WCOM and for the Common Stock Purchase Warrants
shall be calculated as follows;

     (1)     In the event that WCOM fails to Tender, the NETCO Purchase Price
             shall be an amount equal to (m) the Tender Valuation for all shares
             of Common Stock theretofore purchased by WCOM upon exercise of the
             Common Stock Purchase Warrants and/or conversion of the Convertible
             Note, and (n) the difference between the Tender Valuation and the
             exercise price or conversion price, respectively, for the shares of
             Common Stock remaining purchasable upon exercise or conversion,
             respectively, of the Common Stock Purchase Warrants and/or
             Convertible Note.

     (2)     In the event that WCOM's First Tender has been rejected and WCOM
             has not made a Second Tender, the NETCO Purchase Price shall be an
             amount equal to (o) the purchase price offered by WCOM in its
             rejected First Tender for all shares of Common Stock theretofore
             purchased by WCOM upon exercise of the Common Stock Purchase
             Warrants and/or conversion of the Convertible Note, and (p) the
             difference between the purchase price offered by WCOM in its
             rejected First Tender and the exercise price or conversion price,
             respectively, for the shares of Common Stock remaining purchasable
             upon exercise or conversion, respectively, of the Common Stock
             Purchase Warrants and/or Convertible Note.

     (3)     In the event that WCOM's Second Tender has been rejected, the NETCO
             Purchase Price shall be an amount equal to (o) the purchase price
             offered by WCOM in its rejected Second Tender for all shares of
             Common Stock theretofore purchased by WCOM upon exercise of the
             Common Stock Purchase Warrants and/or conversion of the Convertible
             Note, and (p) the difference between the purchase price offered by
             WCOM in its rejected Second Tender and the exercise price or
             conversion price, respectively, for the shares of Common Stock
             remaining purchasable upon exercise or conversion, respectively, of
             the Common Stock Purchase Warrants and/or Convertible Note.

     (f)  NETCO shall have nine (9) months (the "Payment Period") to pay WCOM
the full NETCO Purchase Price for the Common Stock Purchase Warrants and shares
of Common Stock previously issued upon exercise thereof or upon conversion of
the Convertible Note, which shall be computed (i) beginning on the day following
the last day the First Tender or Second Tender may have been accepted, as the
case may be, if WCOM has made a First Tender or Second Tender, or (ii) if WCOM
has not made a First Tender, then beginning on the ninety-first day following
the receipt of the Tender Valuation. For the duration of the Payment Period,
WCOM hereby irrevocably grants to Edward J. Driscoll III and Allen L.

                                       6

 
Witters, jointly and with powers of substitution, the limited proxy in form
attached hereto as Exhibit 5, which shall be deemed an irrevocable proxy coupled
with an interest, to vote in the place and stead of WCOM, any and all shares of
NETCO Common Stock acquired by WCOM upon exercise of the Common Stock Purchase
Warrants or conversion of the Convertible Note. Payment shall be made by NETCO
in good and immediately available funds against assignment and delivery of the
Common Stock Purchase Warrants at NETCO's principal business office at 9:00
A.M., Minneapolis, Minnesota local time, on the tenth (10th) day following
notice from NETCO to WCOM. Should NETCO fail for any reason to timely pay such
purchase price in full during the Payment Period, then, in such event, (i) WCOM
shall be relieved of all further obligations to sell and transfer the Common
Stock Purchase Warrants, or shares previously issued upon exercise thereof or
conversion of the Convertible Note, to NETCO, (ii) NETCO shall have no further
right to require WCOM to sell or convey any of the Common Stock Purchase
Warrants, or shares previously issued upon exercise thereof or conversion of the
Convertible Note, to NETCO, and (iii) NETCO shall not be obligated to pay, and
WCOM shall have no right to receive in payment, any amount determined with
reference to the rights of either party under this Section 4.02.

     4.03  Alternative to Tender or Buy-Back. The provisions of Section 4.02
           ---------------------------------
notwithstanding, NETCO and WCOM may in the future agree upon an alternative
method to provide for and accomplish the intentions expressed in Section 4.01 of
this Agreement; and, upon such future agreement, both NETCO and WCOM shall be
relieved, respectively, of their obligations set forth in Section 4.02. It is
also expressly understood and agreed that, notwithstanding the rejection of
either the First Tender or Second Tender contemplated by Section 4.02(f) and
4.02(e), NETCO and WCOM may nonetheless agree to waive WCOM's and NETCO's
respective obligations of sale and purchase under Section 4.02(d) upon NETCO's
determination to become, and its thereafter becoming, required to file periodic
reports under Section 13(a) or 15(d) of the Securities Exchange Act of 1934 with
its Common Stock listed for trading on the NASDAQ Small Cap Market, the NASDAQ
Stock Market or on a national securities exchange.

credit instrument in form and substance acceptable to WCOM and NETCO for which
the equipment and/or income stream generated by the equipment serves as security
for the repayment thereof.

           --------------------
take the form of recommendation to a commercial lender with whom WCOM does
business, WCOM's guaranty, or partial guaranty, of such Credit Facility, a
secured loan or loans by WCOM, or other assistance reasonably calculated to
assist NETCO to obtain the financing necessary to acquire and install customer
site equipment and/or telephony equipment interconnecting such customer sites;

             VII. REPRESENTATIONS, WARRANTIES AND COVENANTS OF WCOM

     7.01 WCOM hereby represents, warrants and covenants to NETCO that:

     (a)  WCOM has been given access to full and complete information
regarding the Company and has utilized such access to its satisfaction for the
purpose of obtaining information WCOM desires or deems relevant to the decision
to purchase the Preferred Stock, the Subordinated Note and the Common Stock
Purchase Warrants; and particularly, WCOM has had the opportunity to ask
questions of, and receive answers from, representatives of the Company
concerning the terms and conditions of the Note and to obtain any additional
information WCOM desires or deems relevant; and

     (b)  WCOM is aware that the Company is a development stage company; that
the success of the Company is dependent upon the Company's ability to secure
appropriate employees, switching equipment, telephone carriage, integrating
software; also upon the Company's ability to provide adequate installation and
maintenance services; and upon the Company's ability to successfully market its
data transportation technology and services to appropriate customers; and upon
the Company's ability to obtain adequate financing, as contemplated by the
Credit Facilities, to finance its development and operations; and that the
Company can give no assurances that it will be able to successfully obtain,
provide or accomplish any such matters.

     (c)  WCOM has obtained, to the extent it has deemed necessary,
professional advice with respect to the risks inherent in the investment in the
Preferred Stock, the Subordinated Note and the Common Stock Purchase Warrants.

     (d)  WCOM, being a corporation with total assets in excess of $5,000,000
that was not formed for the purpose of acquiring the Note, is an "accredited
investor" within the meaning of Rule 501(a) of the General Rules and Regulations
under the Securities Act of 1933.

                                       11

 
     (e)   WCOM will not use its majority control of NETCO's board of directors
to cause NETCO to waive or fail to enforce any provision of this Agreement for
purposes of frustrating or preventing the intentions of the parties as set
forth in Section 4.01 hereof. Provided, however, that this covenant shall not be
deemed to require any current or future director of NETCO to take, or refrain
from taking, any action which such director reasonably believes, in the exercise
of reasonable business judgment, to be in the best interest of NETCO, or of its
shareholders, in light of the circumstances then prevailing, including any
actions (i) which modify or alter the terms of, or reasonably delay, the
implementation of, the Tender contemplated by Section 4.02 of this Agreement, or
(ii) which relieve WCOM of its obligation to sell the Common Stock Purchase
Warrants, or shares issued upon exercise thereof, to NETCO.

                                   Exhibit 1

                      Statement of Rights and Preferences
                          of Class A Preferred Shares

                            Series A Preferred Stock
                            ------------------------

     Section 1.  Designation and Amount. The shares of the Preferred Stock shall
                 ----------------------
be designated as "Series A Preferred Stock." The number of shares constituting
the Series A Preferred Stock shall be One Hundred Thousand (100,000). Each share
of Series A Preferred Stock shall have a par value of Ten Dollars ($10.00) per
share. The number of shares of Series A Preferred Stock may be increased or
decreased by resolution of the Board of Directors; provided, that, no decrease
shall reduce the number of shares of Series A Preferred Stock to a number less
than the number of shares then outstanding, plus the number of shares, if any,
reserved for issuance upon the exercise of outstanding options, rights or
warrants or upon the conversion of any outstanding securities issued by the
Company convertible into Series A Preferred Stock.

     Section 2.  Dividends and Distributions. (A) The holders of shares of
                 ---------------------------
Series A Preferred Stock, in preference to the holders of Common Stock, par
value $.01 per share (the "Common Stock"), of the Company, shall be entitled to
receive, when, as and if declared by the Board of Directors of the Company (the
"Directors") a dividend (the "Quarterly Dividend") in the amount of One Dollar
and Seventy Five Cents ($1.75) per share payable out of the net earnings of
the Company constituting funds legally available for the purpose. The Quarterly
Dividend shall begin to accrue on January 1, 1997, and shall be payable in cash
on the first day of March, June, September and December in each year (each such
date being referred to herein as a "Quarterly Dividend Payment Date"),
commencing on the first Quarterly Dividend Payment Date after the first issuance
of a share or fraction of a share of Series A Preferred Stock. If the net
earnings in any year are not sufficient to pay the Quarterly Dividend, either in
whole or in part, then any unpaid portion of such dividend will become a charge
against the net earnings of the Company, and will be paid in full out of the net
earnings of the Company in subsequent years before any dividends are paid on the
Common Stock of the Company in those years. No dividends will be paid or set
apart for payment on the Common Stock, no distribution will be made on the
Common Stock, and no shares of Common Stock will be redeemed, retired or
otherwise acquired for valuable consideration unless all theretofore unpaid
Quarterly Dividends have been declared, and the

                                  Exhibit 1-1

 
Company has paid those dividends or has set aside a sum sufficient to pay them.

     (B)  Dividends shall begin to accrue and accumulate on outstanding shares
of Series A Preferred Stock from the Quarterly Dividend Payment Date next
preceding the date of issue of such shares, in which case dividends on such
shares shall begin to accrue from the date of issue of such shares, or unless
the date of issue is a Quarterly Dividend Payment Date or is a date after the
record date for the determination of holders of shares of Series A Preferred
Stock entitled to receive Quarterly Dividends and before such Quarterly Dividend
Payment Date, in either of which events such Quarterly Dividends shall begin to
accrue and accumulate from such Quarterly Dividend Payment Date. Accrued but
unpaid Quarterly Dividends shall not bear interest. Dividends paid on the shares
of Series A Preferred Stock in an amount less than the total amount of Quarterly
Dividends then accrued and payable shall be allocated pro rata on a share-by-
share basis among all such shares of Series A Preferred Stock then outstanding.
The Directors may fix a record date for the determination of holders of shares
of Series A Preferred Stock entitled to receive payment of a dividend or
distribution declared thereon, which record date shall be no more than sixty
(60) days prior to the date fixed for the payment thereof.

     Section 3.  Voting Rights. The holders of shares of Series A Preferred
                 ------------- 
Stock shall have the following voting rights.

     (A)  Each share of Series A Preferred Stock shall entitle the holder
thereof to one vote for each share of Series A Preferred Stock standing in the
name of the holder on the books of the Company. The holders of Series A
Preferred Stock, voting separately as a class, shall be entitled to elect a
majority of the Directors. The right to elect Directors may be exercised at any
annual meeting of the stockholders of the Company, at any special meeting held
in place of an annual meeting, or at a special meeting called to elect
directors. The right to elect directors shall continue until December 31, 1999,
and then expire. The directors elected by the Series A Preferred Stock shall
serve until the next annual or special meeting of the stockholders of the
Company and until their respective successors have been elected by the holders
of Series A Preferred Stock and have been qualified. The term of office of any
person elected as a director by the holders of Series A Preferred Stock shall
terminate on December 31, 1999. The vacancies created thereby may be filled by
resolution of the remaining Directors who shall have been elected by a vote of
the holders of the Common Stock of the Company. If the office of a director
elected by the holders of Series A Preferred Stock is vacant prior to December
31, 1999, due to resignation, removal or death, the vacancy shall be filled by
the majority vote of the directors then in office, even if less than a

                                  Exhibit 1-2

 
quorum, upon the recommendation of the remaining director or directors who were
elected by the holders of the Series A Preferred Stock. If the office of a
director who was elected by the holders of Common Stock is vacant prior to
December 31, 1999, due to resignation, removal or death, the vacancy shall be
filled by the majority vote of the directors then in office, even if less than a
quorum, upon the recommendation of the remaining director or directors who were
elected by the holders of the Common Stock. If the vacancy is not so filled
within forty (40) days after the creation of the vacancy, a special meeting of
the holders of Preferred Stock and/or Common Stock shall be called and the
vacancy or vacancies shall be filled at that meeting.

     (B)  In addition to the right to elect a majority of the Directors as
provided in Section 3(A), the holder of each share of the Series A Preferred
Stock shall be entitled to one vote, voting together with the holders of Common
Stock as a single class, on all matters, excluding the election of Directors,
submitted to the vote of shareholders of the Company.

     (C)  Except as otherwise provided in Section 3(A) or in Section 10
hereof, or in any other Certificate of Designations creating a series of
Preferred Stock, or in any similar stock of the Company hereafter created, or by
law, the holders of shares of Series A Preferred Stock and the holders of shares
of Common Stock and any other capital stock of the Company having general voting
rights shall vote together as one class on all matters submitted to a vote of
stockholders of the Company.

     (D)  Except as expressly set forth herein, or as otherwise provided by
law, holders of Series A Preferred Stock shall have no special voting rights and
their consent shall not be required (except to the extent they are entitled to
vote with holders of Common Stock as set forth herein) for taking any corporate
action.

     Section 4.  Certain Restrictions. (A) Whenever Quarterly Dividends or
                 --------------------  
distributions payable on the Series A Preferred Stock as provided in Section 2
are in arrears, thereafter and until all accrued and unpaid Quarterly Dividends
and distributions, whether or not declared, on shares of Series A Preferred
Stock, outstanding shall have been paid in full, the Company shall not, without
the express affirmative unanimous approval of the Directors elected by holders
of the Series A Preferred Stock:

     (i)  declare or pay dividends, or make any other distributions, on any
     shares of stock ranking junior (either as to dividends or upon liquidation,
     dissolution or winding up) to the Series A Preferred stock;

                                  Exhibit 1-3

 
     (ii)  declare or pay dividends, or make any other distributions, on any
     shares of stock ranking on a parity (either as to dividends or upon
     liquidation, dissolution or winding up) with the Series A Preferred Stock,
     except dividends paid ratably on the Series A Preferred Stock and all such
     parity stock on which dividends are payable or in arrears in proportion to
     the total amounts to which the holders of all such shares are then
     entitled;

     (iii) redeem or purchase or otherwise acquire for consideration shares of
     any stock ranking junior (either as to dividends or upon liquidation,
     dissolution or winding up) to the Series A Preferred Stock, provided that
     the Company may at any time redeem, purchase or otherwise acquire shares of
     any such junior stock in exchange for shares of any stock of the Company
     ranking junior (as to dividends and upon dissolution, liquidation and
     winding up) to the Series A Preferred Stock; or

     (iv)  redeem or purchase or otherwise acquire for consideration any shares
     of Series A Preferred Stock, or any shares of stock ranking on a parity
     (either as to dividends or upon liquidation, dissolution or winding up)
     with the Series A Preferred Stock, except in accordance with a purchase
     offer made in writing or by publication (as determined by the Board) to all
     holders of such shares upon such terms as the Board, after consideration of
     the respective annual dividend rates and other relative rights and
     preferences of the respective series and classes, shall determine in good
     faith will result in fair and equitable treatment among the respective
     series or classes.

     (B)   The Company shall not permit any subsidiary of the Company to
purchase or otherwise acquire for consideration any shares of stock of the
Company unless the Company could, under paragraph (A) of this Section 4,
purchase or otherwise acquire such shares at such time and in such manner.

     Section 5.  Liquidation, Dissolution or Winding up. Upon any voluntary
                 --------------------------------------
or involuntary liquidation, dissolution or winding up of the affairs of the
Company, no distribution shall be made (a) to the holders of shares of stock
ranking junior (either as to dividends or upon liquidation, dissolution or
winding up) to the Series A Preferred Stock, or (b) to the holders of shares of
stock ranking on a parity (either as to dividends or upon liquidation,
dissolution or winding up) with the Series A Preferred Stock unless each holder
of Preferred Stock has received in cash out of the assets of the Company,
whether from capital or earnings, available for distribution to the shareholders
of the Company, before any amount is paid to the holders of Common Stock, the
sum of Ten Dollars ($10.00) per

                                  Exhibit 1-4

 
share for each share of Preferred Stock held by the holder, plus an amount
equal to the sum of all accumulated and unpaid dividends to the date affixed for
the payment of the distribution on the shares of Preferred Stock held by the
holder. The sale or transfer by the Company of all or substantially all of its
assets shall not, for the purposes of determining preferences and liquidation,
be deemed to be a liquidation, dissolution or winding up of the Company.

     Section 6.  Preemptive Rights. No holder of any shares of Series A
                 -----------------  
Preferred stock shall be entitled as such, as a matter of right, to subscribe
for, purchase or receive any part of any class whatsoever, or of securities
convertible into or exchangeable for any stock or any class whatsoever, whether
now or hereafter authorized or whether issued for cash or other consideration or
by way of a dividend.

     Section 7.  Mandatory Redemption. Unless earlier redeemed or acquired
                 --------------------  
in whole or in part by the Company with the consent of the Holder, the shares of
Series A Preferred Stock that remain issued and outstanding shall expire and
shall be automatically redeemed on December 31, 1999, at par value, plus an
amount equal to all accumulated and unpaid dividends, if any, due with respect
to the Preferred Stock (collectively, the "Redemption Price"). Redemption shall
be in cash out of any funds legally available for the redemption of the
Preferred Stock.

     Section 8.  Reacquired Shares. Any shares of Series A Preferred Stock
                 -----------------
purchased or otherwise acquired by the Company in any manner whatsoever shall be
retired and canceled promptly after the acquisition thereof. All such shares
shall upon their cancellation become authorized but unissued shares of
undesignated stock and may be reissued subject to the conditions and
restrictions on issuance in the Articles of Incorporation, or in any other
Certificate of Designations creating a series of Preferred Stock or any similar
stock or as otherwise required by law.

     Section 9.  Rank. The Series A Preferred Stock shall rank, with respect to
                 ----
the payment of dividends and the distribution of assets, senior to all series
of any other class of Preferred Stock.

     Section 10. Amendment. If any proposed amendment to the Articles of
                 ---------
Incorporation or this Certificate of Designation would alter or change the
preferences, special rights or powers given to the Series A Preferred Stock so
as to affect the Series A Preferred Stock adversely, or would authorize the
issuance of a class or classes of stock having preferences or rights with
respect to dividends or dissolution or the distribution of assets that would be
superior to the preferences or rights of the Series A Preferred Stock, then the
holders of the Series A Preferred Stock shall be entitled to vote as a series
upon such amendment, and the

                                  Exhibit 1-5

 
affirmative vote of two-thirds of the outstanding shares of Series A
Preferred Stock shall be necessary to the adoption thereof, in addition to such
other vote as may be required by law.

                                  Exhibit 3-2

 
balance hereof together with all other sums owing hereunder immediately due and
payable, without presentation, demand or further action of any kind.

     2.3) Upon the occurrence of any Event of Default and before and after
acceleration of the entire unpaid principal balance of this Note, interest shall
continue to accrue thereafter at a rate equal to two percent (2%) per annum in
excess of the then applicable rate of interest under this Note until this Note
is paid in full, including the period following entry of any judgment. Both
before and after any default, interest shall be calculated on the basis of a 
360-day year but charged on the basis of actual number of days elapsed in any
calendar year of part thereof.

     2.4) Holder may waive any default before or after the same has been
declared without impairing the Holder's right to declare a subsequent default
hereunder, this right being a continuing right.

     2.5) Upon an Event of Default, Holder shall not be deemed, by any act of
omission or commission to have waived any of its rights or remedies unless such
waiver is in writing and signed by Holder, and then only to the extent
specifically set forth in the writing. A waiver as to one event shall not be
construed as continuing or as a bar to or waiver of any right or remedy as to a
subsequent event.

interest accrued to the date fixed for payment. If the Holder hereof fails or
neglects to present this Note for payment at the time and place specified in

                                    PAYMENT

     4.1) Payment to the Holder of principal and interest shall be a complete
discharge of the Issuer's liability with respect to such payment, but the Issuer
may, at any time, require the presentation hereof as a condition precedent to
such payment.

     4.2) No recourse shall be had for the payment of the principal, or
interest, or for any claim based thereon, or otherwise, against any
incorporator, shareholder, officer, director, or agent, past, present, or
future, of the Issuer, whether by virtue of any

constitution, statute, rule of law, enforcement of any assessment, or penalty,
or by reason of any matter prior to delivery of this Note, or otherwise. All
such liability, by the acceptance hereof, is a part of the consideration to the
Issuer hereof, and is expressly waived.


                                   ARTICLE 5

                                   DIVIDENDS

dividend payable in cash or property on its Common Stock, with the sole
exception of any stock split in the form of a dividend payable in shares of
common stock.


                                   ARTICLE 6

at the

                                  Exhibit 3-4

 
sole discretion of Holder, and the failure to exercise any such right or remedy
shall in no event be construed as a waiver or release of the same.

     7.4) Issuer's obligations hereunder shall extend to and bind Issuer's
successors and assigns. This Note may be amended only by an instrument in
writing signed by both Issuer and Holder.


     IN WITNESS WHEREOF, the Issuer has caused this Note to be signed by its
President and Secretary.

                                       By:______________________________
                                           Edward J. Driscoll, III
                                           President and Secretary

                                  Exhibit 3-5

 
                                   Exhibit 4

                   EXERCISABLE ON OR BEFORE, AND VOID AFTER 
                 5:00 P.M. MINNEAPOLIS TIME DECEMBER 31, 2000

                      Certificate for 4,157,500 Warrants

                     WARRANTS TO PURCHASE COMMON STOCK OF

                       NETCO COMMUNICATIONS CORPORATION

             INCORPORATED UNDER THE LAWS OF THE STATE OF MINNESOTA

         THIS CERTIFIES that WORLDCOM INC., ("Holder") or assigns, is the owner
of the number of Warrants set forth above, each of which represents the right to
purchase from Netco Communications Corporation, a Minnesota corporation (the
"Company"), at any time on or before 5:00 Minneapolis time, December 31, 2000,
upon compliance with and subject to the conditions set forth herein, one share
(subject to adjustments referred to below) of the Common Stock of the Company,
par value $.01 per share (such shares or other securities or property
purchasable upon exercise of the Warrants being herein called the "Shares").

         Upon any exercise of less than all the Warrants evidenced by this
Warrant Certificate, there shall be issued to the Holder a new Warrant
Certificate in respect of the Warrants as to which this Warrant Certificate was
not exercised.

This Warrant is subject to the following provisions, terms and conditions:

         1. Exercise; Transferability. The rights represented by this Warrant
            -------------------------
may be exercised by the Holder hereof, in whole or in part (but not as to a
fractional share of Common Stock), by written notice of exercise delivered to
the Company ten (10) days prior to the intended date of exercise and by the
surrender of this Warrant (properly endorsed if required) at the principal
office of the Company and by paying in full, as provided herein, the purchase
price of $4.81 per share (the "Initial Exercise Price" subject to adjustments as
noted subsequently).

         Payment upon exercise of the rights represented by this Warrant may be
made at the option of the Holder (a) in cash or by certified or official bank
check payable to the order of the Company, (b) by surrendering to the Company
for cancellation and retirement any number shares of Class A Preferred Shares,
par value $10.00 per share, which shares shall each be valued for purposes
hereof at

                                  Exhibit 4-1

 
their par value of $10.00 plus the sum of any then accumulated and unpaid
dividends thereon, (c) by cancellation and discharge of the Company from all or
any portion of any debt in the amount then owed by the Company to the Holder on
a dollar for dollar basis, including principal whether or not then due and
payable together with any interest accrued and unpaid thereon, or (d) by any
combination of any or all of the foregoing.

          This Warrant may not be transferred or divided into two or more
Warrants of smaller denominations, nor may any Common Stock issued pursuant to
exercise of this Warrant be transferred unless this Warrant or shares have been
registered under the Securities Act of 1933, as amended ("Securities Act") and
applicable state laws, or unless the Holder of the certificate obtains an
opinion of counsel satisfactory to the Company and its counsel that the proposed
transfer may be effected without registration pursuant to exemptions under the
Securities Act and applicable state laws.

          2.  Issuance of Shares. The Company agrees that the shares purchased
              ------------------
hereby shall be deemed to be issued to the record Holder hereof as of the close
of business on the date on which this Warrant shall have been surrendered and
the payment made for such shares as aforesaid. Subject to the provisions of the
next succeeding paragraph, certificates for the shares of stock so purchased
shall be delivered to the Holder hereof within a reasonable time, not exceeding
ten (10) days after the rights represented by this Warrant shall have been so
exercised, and, unless this Warrant has expired, a new Warrant representing the
number of shares, if any, with respect to which this Warrant shall not then have
been exercised shall also be delivered to the Holder hereof within such time.

          Notwithstanding the foregoing, however, the Company shall not be
required to deliver any certificate for shares of stock upon exercise of this
Warrant, except in accordance with the provisions, and subject to the
limitations, of paragraph 7 hereof.

          3.  Covenants of Company. The Company covenants and agrees that all
              --------------------
shares which may be issued upon the exercise of the rights represented by this
Warrant will, upon issuance, be duly authorized and issued, fully paid,
nonassessable and free from all taxes, liens and charges with respect to the
issue thereof, and without limiting the generality of the foregoing, the Company
covenants and agrees that it will from time to time take all such action as may
be required to assure that the par value per share of the Common Stock is at all
times equal to or less than the then effective purchase price per share of the
Common Stock issuable pursuant to this Warrant. The Company further covenants
and agrees that during the period within which the rights represented by this
Warrant may be exercised, the Company will at all times have authorized, and
reserved for the purpose of issue or transfer upon exercise of the subscription
rights evidenced by this Warrant, a sufficient number of shares of its

                                  Exhibit 4-2

 
Common Stock to provide for the exercise of the rights represented by this
Warrant.

     4.  Adjustments. The above provisions are, however, subject to the
         -----------
following provisions:

     (a) The Initial Exercise Price of $4.81 per share shall increase to $4.94
         per share on March 31, 1997, and shall thereafter increase by the
         amount of $.08 per share on the last day of each calendar quarter
         during the term of the Warrant, commencing with the calendar quarter
         ending June 30, 1997 (such increases beginning with the calendar
         quarter ending June 30, 1997, being referred to as the "Quarterly
         Increase"); provided, that to encourage earlier partial exercise of the
         Warrants, the amount of each Quarterly Increase shall be abated at the
         rate of $.00875 per share (the "Abatement") for each incremental
         purchase of aggregated amounts of Five Hundred Thousand (500,000)
         shares upon partial exercise of this Warrant. Each Abatement shall take
         effect on the last day of the calendar quarter during which such
         partial exercise and purchase occurred, as illustrated by the following
         examples: (i) the purchase of One Million Five Hundred Thousand
         (1,500,000) shares during the second calendar quarter of 1998 would
         result in a reduction, commencing June 30, 1998, of the Quarterly
         Increase to .0625 per share for each subsequent calendar quarter; (ii)
         the further purchase of Five Hundred Thousand (500,000) shares during
         the third calendar quarter of 1998 would result in a further reduction,
         commencing September 30, 1998, of the Quarterly Increase to $.045 per
         share for each subsequent calendar quarter. The exercise price computed
         from time to time in accordance with this provision shall be referred
         to as the "Current Exercise Price."

     (d) In case the Company shall at anytime hereafter subdivide or combine the
         outstanding shares of Common Stock or declare a dividend payable in
         Common Stock, the exercise price of this Warrant in effect immediately
         prior to the subdivision, combination or record date for such dividend
         payable in Common Stock shall forthwith be proportionately increased,
         in the case of combination, or decreased, in the case of subdivision or
         dividend payable in Common Stock, and each share of Common Stock
         purchasable upon exercise of the Warrant shall be changed to the number
         determined by dividing the then Current Exercise Price by the exercise
         price as adjusted after the subdivision, combination, or dividend
         payable in Common Stock.

     (e) No fractional shares of Common Stock are to be issued upon the exercise
         of the Warrant, but the Company shall pay a cash

                                  Exhibit 4-3

 
         adjustment in respect of any fraction of a share which would otherwise
         be issuable in an amount equal to the same fraction of the market price
         per share of Common Stock on the date of exercise as determined in good
         faith by the Company.

     (f) If any capital reorganization or reclassification of the capital stock
         of the Company, or consolidation or merger of the Company with another
         corporation, or the sale of all or substantially all of its assets to
         another corporation shall be effected in such a way that holders of
         Common Stock shall be entitled to receive stock, securities or assets
         with respect to or in exchange for Common Stock then, as a condition of
         such reorganization, reclassification, consolidation, merger or sale,
         lawful and adequate provision shall be made whereby the Holder hereof
         shall hereafter have the right to purchase and receive upon the basis
         and upon the terms and conditions specified in this Warrant and in lieu
         of the shares of the Common Stock of the Company immediately
         theretofore purchasable and receivable upon the exercise of the rights
         represented hereby, such shares of stock, securities or assets as may
         be issued and payable with respect to or in exchange for a number of
         outstanding shares of such Common Stock equal to the number of shares
         of such stock immediately theretofore purchasable and receivable upon
         the exercise of the rights represented hereby had such reorganization,
         reclassification, consolidation, merger or sale not taken place, and in
         any such case appropriate provisions shall be made with respect to the
         rights and interests of the Holder of this Warrant to the end that the
         provisions hereof (including without limitation provisions for
         adjustments of the Warrant purchase price and of the number of shares
         purchasable upon the exercise of this Warrant) shall thereafter be
         applicable, as nearly as may be, in relation to any shares of stock,
         securities or assets thereafter deliverable upon the exercise hereof.
         The Company shall not effect any such consolidation, merger or sale,
         unless prior to the consummation thereof the successor corporation (if
         other than the Company) resulting from such consolidation, merger, or
         the corporation purchasing such assets shall assume by written
         instrument executed and mailed to the registered Holder hereof at the
         last address of such holder appearing on the books of the Company, the
         obligation to deliver to such holder such shares of stock, securities
         or assets as, in accordance with the foregoing provisions, such holder
         may be entitled to purchase.

     (g) If the Company shall at any time or from time to time (i) distribute
         (otherwise than as a dividend in cash or in Common Stock or securities
         convertible into or exchangeable for Common Stock) to the holders of
         Common Stock any property or other securities, or

                                  Exhibit 4-4

 
          (ii) declare a dividend upon the Common Stock (to the extent payable
          otherwise than out of earnings or earned surplus, as indicated by the
          accounting treatment of such dividend in the books of the Company, and
          otherwise than in Common Stock or securities convertible into or
          exchangeable for Common Stock), the Company shall reserve and the
          Holder of this Warrant shall thereafter upon exercise hereof be
          entitled to receive, with respect to each share of Common Stock
          purchased hereunder, without any change in, or payment in addition to,
          the exercise price, the amount of any property or other securities
          which would have been distributable to such holder had such holder
          been a holder of one share of Common Stock on the record date of such
          distribution or dividend (or if no record date was established by the
          Company, the date such distribution or dividend was paid).

     (h)  Upon any adjustment of the Current Exercise Price, then and in each
          such case, the Company shall give written notice thereof, by first
          class mail, postage prepaid, addressed to the registered holder of
          this Warrant at the address of such holder as shown on the books of
          the Company, which notice shall state the exercise price resulting
          from such adjustment and the increase or decrease, if any, in the
          number of shares purchasable at such price upon the exercise of this
          Warrant, setting forth in reasonable detail the method of calculation
          and the facts upon which such calculation is based.

     5. Common Stock. As used herein, the term "Common Stock" means the
        ------------ 
Company's presently authorized shares of Common Stock and shall also include any
capital stock of any class of the Company hereafter authorized which shall not
be limited to fixed sum or percentage in respect of the rights of the holders
thereof to participate in dividends or in the distribution of assets upon the
voluntary or involuntary liquidation, dissolution or winding up of the Company.

     6. No Voting Rights. This Warrant shall not entitle the Holder hereof to
        ----------------   
any voting rights or other rights as a stockholder of the Company.

     7. Notice of Transfer of Warrant or Resale of Shares. The Holder of this
        -------------------------------------------------  
Warrant, by acceptance hereof, agrees to give written notice to the Company
before transferring this Warrant, or transferring any Common Stock issued upon
the exercise hereof, of such holder's intention to do so, describing briefly the
manner of any proposed transfer. Promptly upon receiving such written notice the
Company shall present copies thereof to the Company counsel and if in the
opinion of such counsel the proposed transfer complies with federal and state
securities laws and may be effected without registration or qualification (under
any Federal or State law), the Company, as promptly as practicable, shall notify
such holder of such opinion, whereupon such holder shall be entitled to transfer

                                  Exhibit 4-5

 
this Warrant or to dispose of shares of Common Stock received upon the previous
exercise of this Warrant, provided that an appropriate legend may be endorsed on
this Warrant or the certificates for such shares respecting restrictions upon
transfer thereof necessary or advisable in the opinion of counsel to the Company
to prevent further transfers which would be in violation of Section 5 of the
Securities Act of 1933.

         If in the opinion of Company's counsel referred to in this paragraph 7
hereof, the proposed transfer or disposition of shares described in the written
notice given pursuant to this paragraph 7 may not be effected without
registration or qualification of this Warrant or the shares of Common Stock
issued on the exercise hereof, the Company shall promptly give written notice
thereof to the Holder hereof, and the Holder will limit its activities in
respect to such as, in the opinion of such counsel, are permitted by law.

         8. Registration Rights. If the Company, at any time after three (3)
            -------------------
years from the date hereof until two (2) years after the complete exercise of
this Warrant, but in any event no later March 31, 2003, proposes to claim an
exemption under Section 3(b) for a public offering of any of its securities or
to register under the Securities Act of 1933 (except by a Form S-8 or other
inappropriate Form for registration) any of its securities, it will give written
notice to all registered holders of Warrants, and all registered holders of
shares of Common Stock acquired upon the exercise of Warrants, of its intention
to do so and, on the written request of any registered holders given within
twenty (20) days after receipt of any such notice (which request shall specify
the Warrants or shares of Common Stock intended to be sold or disposed of by
such registered holder and describe the nature of any proposed sale or other
disposition thereof), the Company will use its best efforts to cause all such
Warrants and/or shares, the registered holders of which shall have requested the
registration or qualification thereof, to be included in such notification or
registration statement proposed to be filed by the Company; provided, however,
that no such inclusion shall be required (i) if the Shares may then be sold by
the holder thereof without limitation under Rule 144(k), or comparable successor
rule of the Securities and Exchange Commission, or (ii) if the managing
underwriter of such offering reasonably determines that including such Shares
would unreasonably interfere with such offering. The Company will pay all
expenses of registration. The Warrant holders shall pay all commissions or
discounts applicable to the sale of the included Shares, together with any
expenses of counsel retained by them in connection with their sale of the
Shares.

                                  Exhibit 4-6

 
         IN WITNESS WHEREOF, Netco Communications Corporation, Inc. has caused
this Warrant to be signed by its duly authorized officer and this Warrant to be
dated November ___, 1996.

                                               NETCO COMMUNICATIONS CORPORATION

                                               By: _____________________________
                                                   Edward J. Driscoll, III 
                                                   President

                                   Exhibit 5

                       NETCO COMMUNICATIONS CORPORATION

              IRREVOCABLE, LIMITED PROXY COUPLED WITH AN INTEREST

         WorldCom Inc. ("WCOM") hereby irrevocably appoints Edward J. Driscoll,
III, and Allen L. Witters as Proxies (each with the power to act alone and with
the power of substitution and revocation) to represent the undersigned and to
vote, as designated and limited below, all Common Shares of Netco Communications
Corporation ("NETCO") held of record by the undersigned during the Payment
Period.

         This Proxy is given pursuant to section 4.02(e) of that certain
Preferred Stock, Subordinated Note and Warrant Purchase Agreement ("Purchase
Agreement") between WCOM and NETCO dated November 14, 1996. Capitalized terms
used and not otherwise defined in this Proxy shall have the meanings ascribed to
them in the Purchase Agreement.

         The Proxies are authorized during the Payment Period to vote in their
discretion upon all matters which may come before any meeting of shareholders of
NETCO during the Payment Period, including the election of directors; provided,
however, that the Proxies are not authorized to vote in favor of any proposal
which approves any merger, sale or exchange of assets, or other transaction
requiring shareholder approval unless a principle purpose of such transaction is
to permit NETCO to obtain the financing and/or funds that are necessary, and
that are used, to pay WCOM the full purchase price (pursuant to section 4.02(d)
of the Purchase Agreement) for the Warrants and/or the shares of NETCO Common
Stock theretofore issued upon exercise of the Warrants or conversion of the
Convertible Note.

         WCOM retains the right to vote on all other matters submitted to NETCO
shareholders for which the Proxies are not expressly authorized to vote.

         This Proxy is coupled with an interest and is irrevocable until
expiration of the Payment Period.

Agreement, the Corporation hereby employs Executive and Executive hereby

               ---------------------------------------
Agreement, Executive shall serve as Chief Executive Officer of the Corporation.
As such, Executive shall be responsible for the overall direction of the

                                 Exhibit 6 - 1

 
position and such authority as shall be required to enable him to perform these
duties, including but not limited to the authorities and duties currently
prescribed in the Articles of Incorporation and the Bylaws of the Corporation,
subject to the power of the shareholders and/or directors of the Corporation to

subject only to the general direction, approval, and control of the
Corporation's Board of Directors, for formulating policies and administering
the Corporation in all respects. His powers shall include authority to hire and
fire Corporation personnel, except for members of the Board of Directors who are
also employees of the Corporation, and to retain consultants when he deems
necessary to implement Corporation policies.

          3.)  Location of Employment. Executive's services shall be rendered
               ---------------------- 
principally in Minneapolis, Minnesota and Executive shall not be required,

          4.)  Compensation, Benefits, Expenses.
               --------------------------------
 
          (a)  Salary. The Corporation shall pay Executive a base salary at an
               ------
          annual rate of $150,000.00 commencing October 1, 1996. Salary shall be
          paid in accordance with the Corporation's regular payroll procedure,
          but not less frequently than monthly. Executive's base salary shall be
          reviewed periodically (at intervals of not more than 12 months) by the
          Board of Directors of the Corporation ("the Board of Directors" or
          "Board") or a committee thereof for the purpose of considering
          increases thereof. In evaluating increases in salary, such factors as
          corporate performance, individual merit, inflation and other
          appropriate considerations shall be taken into account.

          (b)  Stock Option. In addition to any other compensation or benefits
               ------------
          to which the Executive may be entitled under this Agreement or
          otherwise, Executive shall receive options to acquire Four Hundred
          Thousand (400,000) shares of the capital stock of the Corporation in
          accordance with the terms of that certain Stock Option Agreement which
          is attached hereto and marked Exhibit A.

          (c)  Bonus and Other Compensation. The Executive shall be entitled to
               ----------------------------
          additional bonus and other compensation as may be established from
          time to time by the Board of Directors based upon an annual business
          plan which shall set goals (which shall include achievement of revenue
          and

                                 Exhibit 6 - 2

 
          profit measures which are reasonable at the time established) for the
          Corporation.

          (d)  Vacation.  During each year of his employment, Executive will be
               --------
          entitled to reasonable vacations not exceeding five weeks per year,
          holidays and time off when ill, all at full pay. Vacations shall be at
          such time or times and for such periods as Employer and Executive
          shall agree.

          (e)  Automobiles.  The Corporation recognizes the Executive's need for
               -----------
          an automobile or automobiles for business purposes. It, therefore,
          shall provide the Executive with a reasonably suitable automobile or
          automobiles, including all related maintenance, repairs, insurance and
          other costs associated with such automobiles during the term of this
          Agreement or any renewal or extension thereof.

          (f)  Expenses.  The Corporation recognizes that Executive will have to
               --------
          incur certain out-of-pocket expenses related to his services and the
          Corporation's business and that it will be extremely difficult to
          account for such expenses. It is understood that Executive's
          compensation is intended to cover all such out-of-pocket expenses. The
          Corporation, however, shall reimburse Executive for any specific
          expenditures incurred for travel, lodging, entertainment, and the like
          upon submission of appropriate receipts and documentation sufficient
          to substantiate them as reasonable and necessary business expenses.

          (g)  Employee Benefits.  This Agreement shall not be in lieu of any
               -----------------
          rights, benefits and privileges to which Executive may be entitled as
          an employee of the Corporation under any retirement, pension,
          profit-sharing, insurance, group life insurance, hospitalization,
          surgical and major medical coverage, and long-term disability or other
          plans which may now be in effect or which may hereafter be adopted.
          Executive shall have the same rights and privileges to participate in
          such plans and benefits as any other employee during his period of
          employment. In addition, to the extent appropriate for a senior
          executive of the Corporation, Executive shall be entitled to
          participate in any pension and retirement plans, bonus plans and such
          other fringe benefit programs or plans as are or may be made available
          from time to time to executive and/or other salaried Executives of the
          Corporation.

     written consent of the Corporation, directly or indirectly, as an
     Executive, employer, agent, principal, proprietor, partner, stockholder,
     consultant, director, or corporate officer, engage in any business engaged
     in the high-speed, transaction based electronic data transportation and
     delivery business (the "Competitive Business") or render any services to
     any business that is engaged in a Competitive Business.

     (b)  For a period of two years (the "Non-Competition Period") after
     Executive has ceased to be employed by the Corporation or any subsidiary of
     the Corporation, Executive shall not without the prior written consent of
     the Corporation:

          (1)  directly or indirectly engage in, or

          (2)  be employed by any person, firm, partnership, association,
               corporation or business organization, entity or enterprise that
               is, or is about to become, directly or indirectly engaged in,

     any Competitive Business. For purposes hereof, "Competitive Business" shall
     mean engaging or having a material interest, directly or indirectly as
     owner, employee, officer, director, partner, venturer or stockholder,
     capital investor, consultant, agent, principal advisor or otherwise, either
     alone or in association with others, in the operation of a high speed,
     transaction based, electronic data transportation and delivery business;
     provided, however, that the restrictions contained in this Subparagraph (b)
     shall not apply to any business that does not meet both of the following
     requirements:

          (1)  the Corporation or a subsidiary of the Corporation shall have
               operated such business, or had such business in the planning or
               development stage therein, during the 120-day period

                                 Exhibit 6 - 7

 
               immediately prior to Executive's ceasing to be employed by the
               Corporation or any subsidiary of the Corporation, and

          (2)  Executive, during such period, shall have had substantial
               planning, development, administrative or operational
               responsibilities for such business of the corporation or such
               subsidiary of the Corporation in such area.

     (c)  Executive shall not during the Non-Competition Period (i) solicit any
     employee of the Corporation to engage in a Competitive Business, or (ii)
     personally solicit customers of the Corporation in a manner which is
     competitive with the Corporation.

     (d)  If the scope of any restrictions contained in Subparagraphs 6(a), (b)
     or (c) hereof are too broad to permit enforcement of such restrictions to
     their full extent, then such restrictions shall be enforced to the maximum
     extent permitted by law, and Executive hereby consents and agrees that such
     scope may be judicially modified accordingly in any proceeding brought to
     enforce such restrictions. Ownership of less than five (5%) percent of the
     outstanding stock of a corporation traded on a national securities exchange
     shall not be deemed to breach or conflict with the provisions of
     Subparagraphs (a) or (b) of this Section 6.

manner whatsoever any information concerning any matters affecting or relating
to the business of the Corporation, including without limiting the generality of
the foregoing, any of its customers, the prices it obtains or has obtained from
the sale of, or at which it sells or has sold, its products, or any other
information concerning the business of the Corporation, its manner of operation,
its plans, processes, or other data without regard to whether all of the
foregoing matters will be deemed confidential, material, or important, the
parties hereto stipulating that as between them, the same are important,
material, and confidential and gravely affect the effective and successful
conduct of the business of the Corporation, and the Corporation's good will, and
that any breach of the terms of this paragraph shall be a material breach of
this Agreement.

     8.)  Disclosure and Assignment.  Except as provided elsewhere in this
          -------------------------
Agreement, Executive shall treat as for the Corporation's sole benefit and fully
and promptly disclose to the Corporation, without additional compensation, all
ideas, discoveries, inventions and improvements, whether patentable or not,
relating to high-speed, transaction based electronic data transportation and
delivery services, which while the Executive is employed by the Corporation are
made, conceived or reduced to practice by Executive, alone or with others,
during or after usual working hours, either on or off the job, and Executive
hereby

                                 Exhibit 6 - 8

no equipment, supplies, facility or trade secret information of the Corporation
was used, and which was developed entirely on Executive's own time, and (1)
          ---                                                       ---
which does not relate (a) directly to high-speed, transaction based electronic
data transportation and delivery or (b) to the Corporation's actual or
demonstrably anticipated research or development, or (2) which does not result
from any work performed by Executive for the Corporation. Executive will,
nonetheless, promptly disclose all such ideas, discoveries, inventions and
improvements to the Corporation and offer to the Corporation the right of first
refusal to enter into a license or purchase agreement covering the subject idea,
discovery, invention or improvement on terms mutually agreed to by Executive and
the Corporation. In the event the Corporation and Executive cannot agree on
terms and Executive receives an offer to enter into a license or purchase
agreement with some other party on terms more favorable to that other party than
the terms offered to the Corporation, then the Corporation shall have the right
and Executive shall have the obligation to offer to the Corporation the idea,
discovery, invention or improvement on such terms as offered to the other party.
When such an offer is made to the Corporation pursuant to the preceding
sentence, it must be accepted by the Corporation within thirty (30) days; or if
not accepted, the right of first refusal hereunder as to that offer shall
terminate.

     NOTICE:  Paragraph 9 hereof requires Executive to assign rights to
inventions to the Corporation or its successors. Minnesota Statutes (S) 181.78
limits the scope of agreements requiring the inventions be assigned to
employers. The statute states that such assignment agreements do not apply:

          "to an invention for which no equipment, supplies, facility or trade
          secret information of the employer was used and which was developed
                                                      ---
          entirely on the Executive's own time, and (1) which does not relate
                                                ---
          (a) directly to the business of the employer or (b) to the employer's
          actual or demonstrably anticipated research or development, or (2)
          which does not result from any work performed by the Executive for the
          employer." (Underlining added).

     Please note that Paragraph 9 of this Agreement uses these statutory terms
to define the inventions which are not automatically assigned to the Corporation
but instead are subject to a right of first refusal in favor of the Corporation.

                                 Exhibit 6 - 9

 
     10.) Assistance to the Corporation. Executive shall give the Corporation, 
          -----------------------------
at the Corporation's expense, all assistance the Corporation reasonably requires
to perfect, protect, and exercise the rights to all ideas, discoveries,
inventions or improvements acquired by the Corporation pursuant to the
assignment provisions of Paragraph 8 of this Agreement or the right of first
refusal provisions of Paragraph 9 of this Agreement.

     11.) Documents and Tangible Property. All documents or other tangible
          --------------------------------
property relating in any way to the business of the Corporation which are
conceived or generated by Executive or come into Executive's possession during
Executive's employment shall be and remain the Corporation's exclusive property,
and Executive agrees to return all such documents and tangible property to the
Corporation upon termination of Executive's employment by the Corporation or at
such earlier or later time the Corporation may request Executive to do so.

     12.) Remedies for Breach of Covenants of Executive. The covenants set
          ---------------------------------------------
forth in Paragraphs 6, 7, 8, 9, 10 and 11 of this Agreement shall continue to be
binding upon Executive, notwithstanding the termination of his employment with
the Corporation for any reason whatsoever. Such covenants shall be deemed and
construed as separate agreements independent of any other provisions of this
Agreement. The existence of any claim or cause of action by Executive against
the Corporation, whether predicated on this Agreement or otherwise, shall not
constitute a defense to the enforcement by the Corporation or any or all of such
covenants. It is expressly agreed that the remedy at law for the breach of any
such covenant is inadequate and that temporary and permanent injunctive relief
shall be available to prevent the breach or any threatened breach thereof,
without the necessity of proof of actual damages; provided, however, that it is
expressly agreed that the provisions of Subparagraph 6(b) shall immediately
become void and no longer of any effect whatsoever in the event of a merger or
consolidation of the Corporation into another corporation in which the
Corporation is not the surviving corporation or which requires the stockholders
of the Corporation to exchange their shares of Common Stock of the Corporation
for any other class of capital stock, expressly excepting any transaction
involving the issuance of the capital stock of WorldCom Inc. The termination of
such provision shall be effective on the effective date of such merger or
consolidation.

     13.) Notices.  Any notices to be given hereunder by either party to the
          -------
other may be effected either by personal delivery in writing or by mail,
registered or certified, postage prepaid, with return receipt requested.
Personal delivery to the Corporation shall mean personal delivery to the
Chairman of the Board of Directors. Mailed notices shall be addressed to the
respective addresses shown below. Either party may change its address for notice
by giving written notice in accordance with the terms of this Paragraph 13.

        (a) The Corporation's rights and obligations under this Agreement shall
        inure to the benefit of and shall be binding upon the Corporation's
        successors and assigns.

        (b) In the event of a merger or consolidation of the Corporation with
        any other corporation or corporations, the sale by the Corporation of a
        major portion of its assets or of its business and goodwill, or any
        other corporate reorganization involving the Corporation, this Agreement
        shall be assigned and transferred to such successor in interest as an
        asset of the Corporation; and the Corporation agrees that it shall make
        it a condition of such sale or transfer agreement that the purchaser or
        assignee shall assume the Corporation's obligations under this
        Agreement.

        (c) In the event of any such assignment, the Executive agrees to
        continue to perform his duties according to the terms of this Agreement
        to or for such assignee or transferee of this Agreement; provided,
        however, the Corporation shall remain secondarily liable as a guarantor
        of such assignee's or transferee's obligations to the Executive under
        this Agreement. The Executive acknowledges that his services are unique
        and personal, and, accordingly, the Executive may not assign his rights
        (except the right to receive payments due to him) or delegate his duties
        or obligations under this Agreement.

                                Exhibit 6 - 11

 
        15.) General Provisions.

             ------------------
        be illegal, invalid, or unenforceable under present or future laws
        effective during the term hereof, such provision shall be fully
        severable and this Agreement shall be construed and enforced as if such
        illegal, invalid, or unenforceable provision had never comprised a part
        hereof; and the remaining provisions hereof shall remain in full force
        and effect and shall not be affected by the illegal, invalid, or

        lieu of such illegal, invalid, or unenforceable provision there shall be
        added automatically as a part of this Agreement a provision as similar
        in terms to such illegal, invalid, or unenforceable provision as may be
        possible and still be legal, valid or enforceable.

             ----------------
        understanding of the parties and supersedes all prior agreements or
        understandings, whether written or oral, with respect to the subject
        matter hereof. The prior Employment Agreement dated September 24, 1994
        between the parties hereto is terminated. No terms, conditions,

             ------
        instances upon performance of any term or condition of this Agreement
        shall not be construed a waiver of its future performance. The
        obligations of either party with respect to such term, covenant or
        condition shall continue in full force and effect.

        (f)  Titles. Titles of the paragraphs herein are used solely for
             ------
        convenience and shall not be used for interpretation or construing any
        word, clause, paragraph, or provision of this Agreement.

        (g)  Counterparts. This Agreement may be executed in two or more

                       Section IV - Exercise and Payment

          ------------------
the Board of the Corporation at the Corporation's principal place of business,
accompanied by payment in cash or exercise of the Conversion Right as provided,
respectively, in Paragraphs 4.02 or 4.03 hereof, or by some combination thereof.
The notice shall specify how many shares are being acquired for cash in
accordance with Paragraph 4.02 hereof, and how many by exercise of the
Conversion Right in accordance with Paragraph 4.03 hereof. The notice shall also
be accompanied by any document reasonably required by the Corporation to be
executed by Executive acknowledging the applicable restrictions on the transfer
of the common shares being purchased as set forth under Section 7.02 of this
Agreement.

     4.02 Payment in Cash. The notice specified in Paragraph 4.01 hereof shall
          ---------------
be accompanied by payment of the option price for the shares being purchased for
cash, which shall be in the form of cash or cashier's check or certified check
or, in the sole discretion of the Board, or the Committee if such exists, by
such other form of payment acceptable to the Corporation.

     4.03 Payment by Exercise of Conversion Right.  In the alternative, the
          ---------------------------------------
notice specified in Paragraph 4.01 hereof shall be accompanied by payment for

paragraph. The holder of this option shall have the right to require the
Corporation to convert this option, to the extent then vested, to shares of
Common Stock of the Corporation at any time prior to December 31, 2006. Upon
exercise of the Conversion Right, the Corporation shall deliver to the holder of
this Option (without payment of the exercise price in cash or check as provided
in Paragraph 4.02 thereof) shares of the Corporation's common Stock in number
equal to the quotient obtained by dividing 

                                 Exhibit 6A-3


 
                            Edward J. Driscoll, III
                            Stock Option Agreement
                                ________, 1996

     (a)  the value of the Option at the time the Conversion Right is exercised
          (determined by subtracting the aggregate Option exercise price at the
          time the Conversion Right is exercised) from the aggregate Fair Market
          Value, as determined immediately prior to the exercise of the
          Conversion Right, of the aggregate Fair Market Value of the shares for
          which the Option may be exercised by

     (b)  the Fair Market Value of one share of common stock immediately prior
          to the exercise of the Conversion Right.

The immediately preceding formula is illustrated by the following example where
(i) the number of optioned shares being acquired by exercise of the Conversion
Right is 10,000, (ii) the per share exercise price of the Option is $4.81, and
(iii) the applicable Fair Market Value is $14.43: [(10,000 x 14.43) - (10,000 x
4.81)] / 14.43 = [144,300 - 48,100] / 14.43 = 96,200 / 14.43 = 6,667 shares.

     4.04 Delivery of Certificates. Upon receipt of the Notice of Exercise,
          ------------------------
together with any document specified in Paragraph 4.01 hereof accompanied by
payment in accordance with either Paragraph 4.02 or 4.03 hereof, the Corporation
will deliver to the holder of this Option a certificate or certificates for the
number of shares of common stock issuable thereupon, together with a payment in
cash in lieu of any fraction of a share. The Corporation shall make prompt
delivery of a certificate or certificates representing such common shares,
provided that if any law or regulation requires the Corporation to take any
action with respect to the common shares specified in such notice before the
issuance thereof, then the date of delivery of such common shares shall be
extended for the period necessary to take such action.

     4.05 Fair Market Value. "Fair Market Value" of a share of the Corporation's
          -----------------
common stock as of a particular date (the "Determination Date") shall mean:

     (a)  If the Corporation's common stock is traded on an exchange or is
          quoted on NASDAQ, then the average closing or last sale prices,
          respectively, reported for the ten (10) business days immediately
          preceding the Determination Date;

     (b)  If the Corporation's common stock is not traded on an exchange or on
          NASDAQ, but is traded in the over-the-counter securities market, then
          the average closing bid and asked prices reported for the ten (10)
          business days immediately preceding the Determination Date; and

                                ________, 1996

     (c)  If the Corporation's common stock is not publicly traded, then the
          Fair Market Value as determined in good faith by the Company's Board
          of Directors upon advice of a national investment banking firm whom,
          upon request of the holder of this Option, the Corporation shall
          select and retain to render such valuation.

          should Executive die within three months of termination of employment

the number of issued common shares of the Corporation shall be increased or
reduced by change in par value, split up, reverse split, reclassification,
distribution of a dividend payable in stock, or the like, the number of common

agree as follows:

     1.)  Term of Employment. Subject to the terms and conditions of this
          ------------------ 
Agreement, the Corporation hereby employs Executive and Executive hereby accepts
employment for the period commencing October 1, 1996, and ending December 31,
1998, and thereafter for successive one year periods ending December 31 of each
succeeding year unless and until the employment is terminated in accordance with
the provisions of this Agreement. Each December 31, commencing December 31,

     2.)  Duties, Responsibilities, and Authority. During the term of this
          ---------------------------------------
Agreement, Executive shall serve as Chief Technology Officer of the Corporation.
As such, Executive shall be responsible for the overall management and direction
of the technology, infrastructure and technical network operations of the
Corporation, and he shall have such duties as are generally appropriate to his
position and such authority as shall be required to enable him to perform these
duties, including but not limited to the authorities and duties currently
prescribed in the Articles of Incorporation and the Bylaws of the Corporation,
subject to the power of the shareholders and/or directors of the Corporation to
amend or modify such Articles of Incorporation or Bylaws. The Executive shall
exert his best efforts and devote

                                 Exhibit 7 - 1

 
substantially all of his time and attention to the Corporation's business. The
Executive shall be in charge of the development of technology and infrastructure
of the Corporation, and shall have full authority and responsibility, subject
only to the direction, approval, and control of the Corporation's Chief
Executive Officer, and to the general direction, approval and control of the
Corporation's Board of Directors, for formulating technology policies and
administering the Corporation's technology services and products in all
respects. His powers shall include authority, upon consultation of the
Corporation's Chief Executive Officer, to hire and fire Corporation personnel in
his department and, with the permission of the Corporation's Chief Executive
Officer, to retain consultants when he deems necessary to implement Corporation
policies.

     3.)  Location of Employment.  Executive's services shall be rendered
          ----------------------
principally in Minneapolis, Minnesota and Executive shall not be required,
without his consent, to change his residence or work location from either
Hennepin County or Ramsey County, Minnesota by virtue of his employment with the
Corporation.

     4.)  Compensation, Benefits, Expenses.
          --------------------------------

     (a)  Salary. The Corporation shall pay Executive a base salary at an annual
          ------
     rate of $150,000.00 commencing October 1, 1996. Salary shall be paid in
     accordance with the Corporation's regular payroll procedure, but not less
     frequently than monthly. Executive's base salary shall be reviewed
     periodically (at intervals of not more than 12 months) by the Board of
     Directors of the Corporation ("the Board of Directors" or "Board") or a
     committee thereof for the purpose of considering increases thereof. In
     evaluating increases in salary, such factors as corporate performance,
     individual merit, inflation and other appropriate considerations shall be
     taken into account.

     (b)  Stock Option. In addition to any other compensation or benefits to
          ------------
     which the Executive may be entitled under this Agreement or otherwise,
     Executive shall receive options to acquire Four Hundred Thousand (400,000)
     shares of the capital stork of the Corporation in accordance with the terms
     of that certain Stock Option Agreement which is attached hereto and marked
     Exhibit A.

     (c)  Bonus and Other Compensation. The Executive shall be entitled to
          ----------------------------
     additional bonus and other compensation as may be established from time to
     time by the Board of Directors based upon an annual business plan which
     shall set goals (which shall include achievement of revenue and profit
     measures which are reasonable at the time established) for the Corporation.

     (d)  Vacation.  During each year of his employment, Executive will be
          --------
     entitled to reasonable vacations not exceeding five weeks per year,
     holidays

                                 Exhibit 7 - 2

 
     and time off when ill, all at full pay. Vacations shall be at such time or
     times and for such periods as Employer and Executive shall agree.

     (e)  Automobiles.  The Corporation recognizes the Executive's need for an
          -----------
     automobile or automobiles for business purposes. It, therefore, shall
     provide the Executive with a reasonably suitable automobile or automobiles,
     including all related maintenance, repairs, insurance and other costs
     associated with such automobiles during the term of this Agreement or any
     renewal or extension thereof.

     (f)  Expenses. The Corporation recognizes that Executive will have to incur
          --------          
     certain out-of-pocket expenses related to his services and the
     Corporation's business and that it will be extremely difficult to account
     for such expenses. It is understood that Executive's compensation is
     intended to cover all such out-of-pocket expenses. The Corporation,
     however, shall reimburse Executive for any specific expenditures incurred
     for travel, lodging, entertainment, and the like upon submission of
     appropriate receipts and documentation sufficient to substantiate them as
     reasonable and necessary business expenses.

     (g)  Employee Benefits. This Agreement shall not be in lieu of any rights,
          -----------------
     benefits and privileges to which Executive may be entitled as an employee
     of the Corporation under any retirement, pension, profit-sharing,
     insurance, group life insurance, hospitalization, surgical and major
     medical coverage, and long-term disability or other plans which may now be
     in effect or which may hereafter be adopted. Executive shall have the same
     rights and privileges to participate in such plans and benefits as any
     other employee during his period of employment. In addition, to the extent
     appropriate for a senior executive of the Corporation, Executive shall be
     entitled to participate in any pension and retirement plans, bonus plans
     and such other fringe benefit programs or plans as are or may be made
     available from time to time to executive and/or other salaried Executives
     of the Corporation.

     5.)  Termination.

          involuntary termination with cause), Executive shall be entitled to
          the base salary earned by him prior to the date of termination as
          provided herein computed on a pro rata basis to and including such
          date of termination. In addition, Executive shall also be reimbursed
          for his reasonable business expenses incurred prior to the date of
          termination.

          received by Executive in exchange for his options to purchase shares
          of the Corporation is a non-cash consideration, all stock options
          under the Stock Option Agreement (Exhibit A) that have not theretofore
          vested (including any and all options or rights received or exchanged
          therefor by Executive as a consequence of

                                 Exhibit 7 - 5

 
          the  transaction occurring pursuant to Section 4.02 of the Preferred
          Stock Purchase Agreement) shall immediately vest and become
          exercisable in accordance with the provisions of said Stock Option
          Agreement thereto applicable. In addition, in the event termination
          pursuant to Subparagraph 5(a)(7) occurs on or prior to December 31,
          2000, then Executive shall also receive a lump sum payment in the
          amount of Seventy Five Thousand Dollars ($75,000).

     (3)  If the Corporation terminates this Agreement without cause pursuant to
          Subparagraph 5(a)(2) above (involuntary without cause), Executive
          shall be entitled to receive a severance cash payment as liquidated
          damages for, and in lieu of, any and all damages which he may incur as
          a result of such termination in an amount equal to the greater of (i)
          the Executive's then base salary for two years, or (ii) the amounts
          reasonably estimated to be due hereunder for the two year period
          following the Annual Renewal Date upon which the termination becomes
          effective, which shall be payable within 30 days from the date of
          termination plus, in either case, one half of the cash bonus
          (determined pursuant to Paragraph 4(c) above relating to Bonus and
          Other Compensation), to which Executive would have been entitled had
          he continued in the employment of the Corporation for the year
          following termination, which payment shall be payable in accordance
          with Paragraph 4(b). Additionally, If the Corporation terminates this
          Agreement without cause pursuant to Subparagraph 5(a)(2) above, all
          stock options under the Stock Option Agreement (Exhibit A) that have
          not theretofore vested shall immediately vest and become exercisable
          in accordance with the provisions of said Stock Option Agreement.

     (4)  In the event this Agreement is terminated due to the death (pursuant
          to Subparagraph 6(a)(5)) or disability (pursuant to Subparagraph
          6(a)(6)) of Executive, Executive (or his estate) shall be entitled to
          his then base salary for a period of six months, plus the cash bonus
          payable with respect to the fiscal year of death or disability, in
          accordance with normal payment procedures under this Agreement.

6.)  Non-Competition. Executive covenants and agrees that:
     ---------------

(a)  During the term of this Agreement, he shall not without the prior written
consent of the Corporation, directly or indirectly, as an Executive, employer,
agent, principal, proprietor, partner, stockholder, consultant, director, or
corporate officer, engage in any business engaged in the high- 

                                 Exhibit 7 - 6

 
speed, transaction based electronic data transportation and delivery business
(the "Competitive Business") or render any services to any business that is
engaged in a Competitive Business.

(b)  For a period of two years (the "Non-Competition Period") after Executive
has ceased to be employed by the Corporation or any subsidiary of the
Corporation, Executive shall not without the prior written consent of the
Corporation:

     (1)  directly or indirectly engage in, or

     (2)  be employed by any person, firm, partnership, association, corporation
          or business organization, entity or enterprise that is, or is about to
          become, directly or indirectly engaged in,

any Competitive Business. For purposes hereof, "Competitive Business" shall mean
engaging or having a material interest, directly or indirectly as owner,
employee, officer, director, partner, venturer or stockholder, capital investor,
consultant, agent, principal advisor or otherwise, either alone or in
association with others, in the operation of a high speed, transaction based,
electronic data transportation and delivery business; provided, however, that
the restrictions contained in this Subparagraph (b) shall not apply to any
business that does not meet both of the following requirements:

     (1)  the Corporation or a subsidiary of the Corporation shall have operated
          such business, or had such business in the planning or development
          stage therein, during the 120-day period immediately prior to
          Executive's ceasing to be employed by the Corporation or any
          subsidiary of the Corporation, and

     (2)  Executive, during such period, shall have had substantial planning
          development, administrative or operational responsibilities for such
          business of the corporation or such subsidiary of the Corporation in
          such area.

(c)  Executive shall not during the Non-Competition Period (i) solicit any
employee of the Corporation to engage in a Competitive Business, or (ii)
personally solicit customers of the Corporation in a manner which is competitive
with the Corporation.

(d)  If the scope of any restrictions contained in Subparagraphs 6(a), (b) or
(c) hereof are too broad to permit enforcement of such restrictions to their
full extent, then such restrictions shall be enforced to the maximum extent
permitted by law, and Executive hereby consents and agrees that such scope may
be judicially modified accordingly in any proceeding brought to enforce such
restrictions. Ownership of less than five (5%) percent of the outstanding

                                 Exhibit 7 - 7

 
     stock of a corporation traded on a national securities exchange shall not
     be deemed to breach or conflict with the provisions of Subparagraphs (a) or
     (b) of this Section 6.

     7.)  Trade Secrets.  Executive shall not at any time during the term of 
          -------------
this Agreement or thereafter, or in any manner, either directly or indirectly,
divulge, disclose or communicate to any person, firm or corporation in any
manner whatsoever any information concerning any matters affecting or relating
to the business of the Corporation, including without limiting the generality of
the foregoing, any of its customers, the prices it obtains or has obtained from
the sale of, or at which it sells or has sold, its products, or any other
information concerning the business of the Corporation, its manner of operation,
its plans, processes, or other data without regard to whether all of the
foregoing matters will be deemed confidential, material, or important, the
parties hereto stipulating that as between them, the same are important,
material, and confidential and gravely affect the effective and successful
conduct of the business of the Corporation, and the Corporation's good will, and
that any breach of the terms of this paragraph shall be a material breach of
this Agreement.

     8.)  Disclosure and Assignment. Except as provided elsewhere in this
          -------------------------
Agreement, Executive shall treat as for the Corporation's sole benefit and fully
and promptly disclose to the Corporation, without additional compensation, all
ideas, discoveries, inventions and improvements, whether patentable or not,
relating to high-speed, transaction based electronic data transportation and
delivery services, which while the Executive is employed by the Corporation are
made, conceived or reduced to practice by Executive, alone or with others,
during or after usual working hours, either on or off the job, and Executive
hereby assigns to the Corporation all such ideas, discoveries, inventions and
improvements relating to high-speed, transaction based electronic data
transportation and delivery to be the Corporation's exclusive property.

     9.)  Disclosure and Right of First Refusal. Paragraph 8 of this Agreement
          -------------------------------------
shall not apply to any ideas, discoveries, inventions and improvements for which
no equipment, supplies, facility or trade secret information of the Corporation
was used, and which was developed entirely on Executive's own time, and (1)
          ---                                                       ---
which does not relate (a) directly to high-speed, transaction based electronic
data transportation and delivery or (b) to the Corporation's actual or
demonstrably anticipated research or development, or (2) which does not result
from any work performed by Executive for the Corporation. Executive will,
nonetheless, promptly disclose all such ideas, discoveries, inventions and
improvements to the Corporation and offer to the Corporation the right of first
refusal to enter into a license or purchase agreement covering the subject idea,
discovery, invention or improvement on terms mutually agreed to by Executive and
the Corporation. In the event the Corporation and Executive cannot agree on
terms and Executive receives an offer to enter into a license or purchase
agreement with some other party on terms more favorable to that other party than
the terms offered to the

                                 Exhibit 7 - 8

 
Corporation, then the Corporation shall have the right and Executive shall
have the obligation to offer to the Corporation the idea, discovery, invention
or improvement on such terms as offered to the other party. When such an offer
is made to the Corporation pursuant to the preceding sentence, it must be
accepted by the Corporation within thirty, (30) days; or if not accepted, the
right of first refusal hereunder as to that offer shall terminate.

     NOTICE:  Paragraph 9 hereof requires Executive to assign rights to
inventions to the Corporation or its successors. Minnesota Statutes (S) 181.78
limits the scope of agreements requiring the inventions be assigned to
employers. The statute states that such assignment agreements do not apply:

          "to an invention for which no equipment, supplies, facility
          or trade secret information of the employer was used and
                                                               ---
          which was developed entirely on the Executive's own time,
          and (1) which does not relate (a) directly to the business
          ---
          of the employer or (b) to the employer's actual or
          demonstrably anticipated research or development, or (2)
          which does not result from any work performed by the
          Executive for the employer." (Underlining added).

     Please note that Paragraph 9 of this Agreement uses these statutory terms
to define the inventions which are not automatically assigned to the Corporation
but instead are subject to a right of first refusal in favor of the Corporation.

     10.) Assistance to the Corporation. Executive shall give the Corporation,
          -----------------------------
at the Corporation's expense, all assistance the Corporation reasonably requires
to perfect, protect, and exercise the rights to all ideas, discoveries,
inventions or improvements acquired by the Corporation pursuant to the
assignment provisions of Paragraph 8 of this Agreement or the right of first
refusal provisions of Paragraph 9 of this Agreement.

     11.) Documents and Tangible Property. All documents or other tangible
          -------------------------------
property relating in any way to the business of the Corporation which are
conceived or generated by Executive or come into Executive's possession during
Executive's employment shall be and remain the Corporation's exclusive property,
and Executive agrees to return all such documents and tangible property to the
Corporation upon termination of Executive's employment by the Corporation or at
such earlier or later time the Corporation may request Executive to do so.

     12.) Remedies for Breach of Covenants of Executive. The covenants set
          ---------------------------------------------
forth in Paragraphs 6, 7, 8, 9, 10 and 11 of this Agreement shall continue to be
binding upon Executive, notwithstanding the termination of his employment with
the Corporation for any reason whatsoever. Such covenants shall be deemed and
construed as separate agreements independent of any other provisions of this
Agreement. The existence of any claim or cause of action by Executive against
the 

                                 Exhibit 7 - 9

 
Corporation, whether predicated on this Agreement or otherwise, shall not
constitute a defense to the enforcement by the Corporation or any or all of such
covenants. It is expressly agreed that the remedy at law for the breach of any
such covenant is inadequate and that temporary and permanent injunctive relief
shall be available to prevent the breach or any threatened breach thereof,
without the necessity of proof of actual damages; provided, however, that it is
expressly agreed that the provisions of Subparagraph 6(b) shall immediately
become void and no longer of any effect whatsoever in the event of a merger or
consolidation of the Corporation into another corporation in which the
Corporation is not the surviving corporation or which requires the stockholders
of the Corporation to exchange their shares of Common Stock of the Corporation
for any other class of capital stock, expressly excepting any transaction
involving the issuance of the capital stock of WorldCom Inc. The termination of
such provision shall be effective on the effective date of such merger or
consolidation.

     13.) Notices. Any notices to be given hereunder by either party to the
          -------
other may be effected either by personal delivery in writing or by mail,
registered or certified, postage prepaid, with return receipt requested.
Personal delivery to the Corporation shall mean personal delivery to the
Chairman of the Board of Directors. Mailed notices shall be addressed to the
respective addresses shown below. Either party may change its address for notice
by giving written notice in accordance with the terms of this Paragraph 13.

     inure to the benefit of and shall be binding upon the Corporation's
     successors and assigns.

     (b)  In the event of a merger or consolidation of the Corporation with any
     other corporation or corporations, the sale by the Corporation of a major
     portion of its assets or of its business and goodwill, or any other
     corporate reorganization involving the Corporation, this Agreement shall be
     assigned and transferred to such successor in interest as an asset of the
     Corporation; and the Corporation agrees that it shall make it a condition
     of such sale or transfer agreement that the purchaser or assignee shall
     assume the Corporation's obligations under this Agreement.

     (c)  In the event of any such assignment, the Executive agrees to continue
     to perform his duties according to the terms of this Agreement to or for
     such assignee or transferee of this Agreement; provided, however, the
     Corporation shall remain secondarily liable as a guarantor of such
     assignee's or transferee's obligations to the Executive under this
     Agreement. The Executive acknowledges that his services are unique and
     personal, and, accordingly, the Executive may not assign his rights (except
     the right to receive payments due to him) or delegate his duties or
     obligations under this Agreement.

     15.) General Provisions.
          ------------------

     (a)  Law Governing. This Agreement shall be governed by and construed in
          -------------

          ------------------
     illegal, invalid, or unenforceable under present or future laws effective
     during the term hereof, such provision shall be fully severable and this
     Agreement shall be construed and enforced as if such illegal, invalid, or
     unenforceable provision had never comprised a part hereof; and the
     remaining provisions hereof shall remain in full force and effect and shall
     not be affected by the illegal, invalid, or unenforceable provision or by
     its severance herefrom. Furthermore, in lieu of such illegal, invalid, or
     unenforceable provision there shall be added automatically as a part of
     this Agreement a provision as similar in terms to such illegal, invalid, or
     unenforceable provision as may be possible and still be legal, valid or
     enforceable.

     (c)  Entire Agreement. This Agreement sets forth the entire understanding
          ----------------
     of the parties and supersedes all prior agreements or understandings,

     of either party with respect to such term, covenant or condition shall
     continue in full force and effect.

     (f)  Titles. Titles of the paragraphs herein are used solely for
          ------
     convenience and shall not be used for interpretation or construing any

                       Section IV - Exercise and Payment

the Board of the Corporation at the Corporation's principal place of business,
accompanied by payment in cash or exercise of the Conversion Right as provided,
respectively, in Paragraphs 4.02 or 4.03 hereof, or by some combination thereof.
The notice shall specify how many shares are being acquired for cash in
accordance with Paragraph 4.02 hereof, and how many by exercise of the
Conversion Right in accordance with Paragraph 4.03 hereof. The notice shall also
be accompanied by any document reasonably required by the Corporation to be
executed by Executive acknowledging the applicable restrictions on the transfer
of the common shares being purchased as set forth under Section 7.02 of this
Agreement.

     4.02 Payment in Cash. The notice specified in Paragraph 4.01 hereof shall
          ---------------
be accompanied by payment of the option price for the shares being purchased for
cash, which shall be in the form of cash or cashier's check or certified check
or, in the sole discretion of the Board, or the Committee if such exists, by
such other form of payment acceptable to the Corporation.

     4.03 Payment by Exercise of Conversion Right. In the alternative, the
          ---------------------------------------
notice specified in Paragraph 4.01 hereof shall be accompanied by payment for
the shares being purchased by exercise of the Conversion Right provided in this
paragraph. The holder of this option shall have the right to require the
Corporation to convert this option, to the extent then vested, to shares of
Common Stock of the Corporation at any time prior to December 31, 2006. Upon
exercise of the Conversion Right, the Corporation shall deliver to the holder of
this Option (without payment of the exercise price in cash or check as provided

                                Exhibit 7A - 3

 
                                 Allen Witters
                            Stock Option Agreement 
                                ________, 1996


in Paragraph 4.02 hereof) shares of the Corporation's common Stock in number
equal to the quotient obtained by dividing 
     

     (a)  the value of the Option at the time the Conversion Right is exercised
          (determined by subtracting the aggregate Option exercise price at the
          time the Conversion Right is exercised) from the aggregate Fair Market
          Value, as determined immediately prior to the exercise of the
          Conversion Right, of the aggregate Fair Market Value of the shares for
          which the Option may be exercised by

     (b)  the Fair Market Value of one share of common stock immediately prior
          to the exercise of the Conversion Right.

The immediately preceding formula is illustrated by the following example where
(i) the number of optioned shares being acquired by exercise of the Conversion
Right is 10,000, (ii) the per share exercise price of the Option is $4.81, and
(iii) the applicable Fair Market Value is $14.43: [(10,000 x 14.43) - (10,000 x
4.81)] / 14.43 = [144,300 - 48,100] / 14.43 = 96,200/14.43 = 6,667 shares.

     4.04 Delivery of Certificates. Upon receipt of the Notice of Exercise,
          ------------------------
together with any document specified in Paragraph 4.01 hereof accompanied by
payment in accordance with either Paragraph 4.02 or 4.03 hereof, the Corporation
will deliver to the holder of this Option a certificate or certificates for the
number of shares of common stock issuable thereupon, together with a payment in
cash in lieu of any fraction of a share. The Corporation shall make prompt
delivery of a certificate or certificates representing such common shares,
provided that if any law or regulation requires the Corporation to take any
action with respect to the common shares specified in such notice before the
issuance thereof, then the date of delivery of such common shares shall be
extended for the period necessary to take such action.

     4.05 Fair Market Value.  "Fair Market Value" of a share of the
          -----------------
Corporation's common stock as of a particular date (the "Determination Date")
shall mean:

     (a)  If the Corporation's common stock is traded on an exchange or is
          quoted on NASDAQ then the average closing or last sale prices,
          respectively, reported for the ten (10) business days immediately
          preceding the Determination Date;

     (b)  If the Corporation's common stock is not traded on an exchange or on
          NASDAQ but is traded in the over-the-counter securities market, then

          upon request of the holder of this Option, the Corporation shall
          select and retain to render such valuation.

                            Section V - Termination

          by the Corporation "involuntarily for cause" as that phrase is defined
          in the Employment Agreement.

     (c)  The expiration of twelve months from the date of Executive's death
          should Executive die within three months of termination of employment
          by the Corporation.

therein or herein, or thereunder or hereunder shall be exercisable by anyone
after Dec. 31, 2007.

          Section VI - Reclassification, Consolidation or Merger

     6.01 Reclassification, Split or Dividend. If and to the extent that the
          -----------------------------------
number of issued common shares of the Corporation shall be increased or reduced
by change in par value, split up, reverse split, reclassification, distribution
of a dividend payable in stock, or the like, the number of common shares subject
to the Option and the option price per share shall be proportionately adjusted.

                                 Exhibit 7A-5

 
                                Allen Witters      
                            Stock Option Agreement 
                                ________, 1996

         6.02  Consolidation or Merger. If the Corporation is reorganized or
               -----------------------
consolidated or merged with another corporation, the Executive shall be entitled
to receive an option (the "New Option") covering common shares of such
reorganized, consolidated or merged Corporation in the same proportion, at an
equivalent price, and subject to the same conditions as the Option. For purposes
of the preceding sentence, the excess of the fair market value of the common
shares subject to the Option immediately after the reorganization, consolidation
or merger over the aggregate option price of such common shares shall not be
more than the excess of the aggregate fair market value of all common shares
subject to the Option immediately before such reorganization, consolidation or
merger over the aggregate option price of such common shares, and the New
Option or assumption of the Option shall not give the Executive additional
benefits which he does not have under this Option, or deprive him of benefits
which he has under this Option.

                         VII - Rights and Restrictions

         7.01  Rights Prior to Exercise of Option. This Option is non-
               ----------------------------------
transferable by Executive, except in the event of his death, and during his

four hundred thousand (400,000) shares of the Common Stock of Netco. The four
hundred thousand (400,000) shares of Netco Common Stock presently owned by
Driscoll, together with any additional shares of Netco Common Stock which

execution hereof, entered into a certain Preferred Stock, Subordinated Note

Board of Directors
WorldCom Inc.

Jackson, Mississippi 39201

Ladies and Gentlemen:


          I have acted as counsel for Netco Communications Corporation, a
Minnesota corporation (the "Company"), in connection with the execution and
delivery by the Company of a certain Preferred Stock, Subordinated Note and
Warrant Purchase Agreement (the "Investment Agreement") dated as of November 14,
                                 --------------------
1996, between the Company and WorldCom Inc. ("WCOM"), together with the
execution and delivery by the Company of a 7% Subordinated Note due December 31,
2003 (the "Note") in principal face amount of Twenty Eight Million Five Hundred
           ----
Thousand Dollars ($28,500,000) in favor of WCOM, of a Warrant Certificate (the
"Warrants") representing the right to purchase up to Four Million One Hundred
 --------
Fifty Seven Thousand Five Hundred (4,157,500) shares of the Company's Common
Stock, par value $.01 per share, and the issuance of 100,000 shares of $10,00
par value Class A Preferred Stock of the Company (the "Preferred Stock"), in
accordance with the terms thereof, and the execution of an Executive Employment
Agreement (the "Driscoll Employment Agreement") dated as of ___________, 1996,
                -----------------------------
between the Company and Edward J. Driscoll, III, and of an Executive Employment
Agreement (the "Witters Employment Agreement") dated as of _____________, 1996,
                ----------------------------
between the Company and Allen L. Witters. This opinion is delivered to you
pursuant to Paragraph 8.02(h) of the Investment Agreement.

          The Investment Agreement, the Note, the Warrants, the Preferred Stock,
the Driscoll Employment Agreement and the Witters Employment Agreement are
sometime collectively referred to herein as the "Agreements." Capitalized terms
                                                 ----------
appearing herein that are not otherwise defined shall have the meanings ascribed
to them in the Agreements.

          For purposes of this opinion, I have reviewed such questions of law
and examined such corporate records, certificates and other documents as I have

                                  Exhibit 9-1

 
Board of Directors 
WorldCom Inc.

considered necessary or appropriate. As to various questions of fact, I have
relied without investigation upon representations made in the Agreements and
upon certificates of officers of the Company. I have also examined such
certificates of public officials, corporate documents and records, and other
certificates and instruments, and have engaged in such other investigation as I
have deemed necessary in connection with the opinions hereinafter set forth. I
have assumed the authenticity of all documents submitted to me as originals,
the genuineness of all signatures, the legal capacity of natural persons, the
conformity to the originals of all documents submitted to me as copies, the
valid execution of all agreements and documents referred to herein by all
parties thereto other than the Company and the enforceability of such agreements
against all parties other than the Company.

          Whenever the opinions expressed herein or matters set forth in "Scope
of Opinion" are qualified by or use the phrase "to my knowledge," "known to me"
or words of like import, it indicates that during the course of my
representation of the Company and after reasonable inquiry limited as described
in this letter with respect to the subject matter of any such opinion, no
information has come my attention for such purpose, which would give me
knowledge of the existence or nonexistence of relevant facts. No inference as to
my knowledge of the existence or nonexistence of any facts should, or may be,
drawn merely from the fact that I represent the Company.

          Based upon and subject to the foregoing and subject to the limitations
and qualifications set forth in "Scope of Opinion," I am of the opinion that,
under applicable law in effect on the date of this opinion:

               1.   The Company is duly organized, validly existing and in good
          standing as a corporation under the laws of the state of Minnesota,
          has all corporate power and authority to own its properties and to
          carry on its businesses as now being conducted, and is duly qualified
          and in good standing as a foreign corporation, and is authorized to do
          business, in all jurisdictions in which the character of its
          properties or the nature of its businesses requires such qualification
          or authorization, except for qualifications and authorizations the
          lack of which, singly or in the aggregate, have not had a materially
          adverse effect on the Company.

               2.   The Company has full corporate power and authority to enter
          into the Agreements, and the Agreements have been duly authorized,
          executed and delivered, and, in the case of the Preferred Stock,
          issued by the Company, and constitute valid, legal and binding
          obligations of the Company, and, in the case of the Driscoll
          Employment Agreement and the Witters Employment Agreement, of Driscoll
          and Witters respectively,

          enforceable in accordance with their respective terms (except as such
          enforceability may be limited by bankruptcy, insolvency,
          reorganization or similar laws affecting the rights of creditors
          generally and subject to general principles of equity); the execution,
          delivery and performance of the Agreements and the consummation of the
          transactions therein contemplated will not result in breach or
          violation of any of the terms and provisions of, or constitutes a
          default under, any applicable statute, rule or regulation, any
          material agreement or instrument known to me to which the Company is a

                               Scope of Opinion
                               ----------------

Minnesota and the laws of the United States of America, and the opinions given
hereunder are limited thereto.

          I express no opinion as to the enforceability of cumulative remedies
to the extent such cumulative remedies purport to compensate, or would have the
effect of compensating, the party entitled to the benefits thereof in an amount
in excess of the actual loss suffered by such party.

          Insofar as this opinion relates to the enforceability of any document
or instrument, it is subject to (a) all applicable bankruptcy, insolvency,
reorganization, moratorium and other laws affecting the rights of creditors
generally, (b) judicial limitations on the right of specific performance and
other general principles of equity, regardless of whether such enforceability is
considered in a proceeding in equity or at law which may affect the remedies
provided therein and (c) limitations on the enforceability of any
indemnification or contribution provisions thereof as may be limited by federal
or state securities laws or other applicable laws.
