Securities to be registered pursuant to Section 12(g) of the Act:

                         -------------------------------
                                (Title of class)



Item 1.  Description of Registrant's Securities to be Registered.
- ------   --------------------------------------------------------

         On August 29, 1997, the Board of Directors of Data Transmission Network
Corporation (the "Company")  declared a dividend of one preferred share purchase
right (a "Right") for each  outstanding  share of common stock,  par value $.001
per share,  of the Company  (the  "Common  Stock").  The  dividend is payable on
September  2, 1997 (the  "Record  Date") to the  stockholders  of record on that
date. Each Right entitles the registered holder to purchase from the Company one
one-thousandth of a share of Series A Junior Participating  Preferred Stock, par
value $.50 per  share,  of the  Company  (the  "Preferred  Stock") at a price of
$150.00 per one-thousandth of a share of Preferred Stock (the "Purchase Price"),
subject to adjustment.  The description and terms of the Rights are set forth in
a Rights  Agreement dated as of August 29, 1997, as the same may be amended from
time to time (the "Rights  Agreement"),  between the Company and First  National
Bank of Omaha, as Rights Agent (the "Rights Agent").

         Until  the  earlier  to  occur  of  (i)  10  days  following  a  public
announcement  that a person or group of  affiliated  or  associated  persons (an
"Acquiring  Person")  has  acquired  beneficial  ownership of 11% or more of the
outstanding  shares of Common Stock or (ii) 10 business days (or such later date
as may be  determined by action of a majority of  Continuing  Directors  then in
office prior to such time as any person or group of affiliated  persons  becomes
an Acquiring  Person)  following  the  commencement  of, or  announcement  of an
intention to make, a tender offer or exchange  offer the  consummation  of which
would result in the beneficial  ownership by a person or group of 11% or more of
the  outstanding  shares of Common Stock (the earlier of such dates being called
the "Distribution  Date"), the Rights will be evidenced,  with respect to any of
the Common Stock certificates  outstanding as of the Record Date, by such Common
Stock  certificate  together with a summary  description of the Rights  attached
thereto. The term "Acquiring Person" excludes the Company, any subsidiary of the
Company,  any  employee  benefit  plan of the Company or any  subsidiary  of the
Company, and Roger R. Brodersen (the founder of the Company) and certain related
persons and  entities.  In addition,  any other person  whose  current  level of
beneficial  ownership  exceeds 11% but is less than 14% of the Common Stock will
become an Acquiring Person only if its level of beneficial ownership exceeds 14%
of the Common Stock.

         The Rights Agreement  provides that,  until the  Distribution  Date (or
earlier expiration of the Rights),  the Rights will be transferred with and only
with the Common Stock. Until the Distribution Date (or earlier expiration of the
Rights), new Common Stock certificates issued after the Record Date upon

                                       2


transfer or new issuances of Common Stock will contain a notation  incorporating
the Rights  Agreement  by  reference.  Until the  Distribution  Date (or earlier
expiration of the Rights),  the surrender for transfer of any  certificates  for
shares of Common  Stock  outstanding  as of the Record  Date,  even without such
notation or a summary  description  of the Rights being attached  thereto,  will
also constitute the transfer of the Rights  associated with the shares of Common
Stock  represented by such  certificate.  As soon as  practicable  following the
Distribution  Date,   separate   certificates   evidencing  the  Rights  ("Right
Certificates") will be mailed to holders of record of the Common Stock as of the
close of business on the Distribution Date and such separate Right  Certificates
alone will evidence the Rights.

         The Rights are not exercisable until the Distribution  Date. The Rights
will expire on August 29, 2007 (the "Final Expiration  Date"),  unless the Final
Expiration  Date is  advanced  or  extended  or unless the  Rights  are  earlier
redeemed or exchanged by the Company, in each case as described below.

         The Purchase Price payable, and the number of shares of Preferred Stock
or other securities or property issuable, upon exercise of the Rights is subject
to adjustment from time to time to prevent  dilution (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of, the Preferred
Stock,  (ii) upon the grant to holders of the Preferred  Stock of certain rights
or  warrants  to  subscribe  for or  purchase  Preferred  Stock at a  price,  or
securities  convertible into Preferred Stock with a conversion  price, less than
the  then  current  market  price  of the  Preferred  Stock  or  (iii)  upon the
distribution  to holders of the Preferred  Stock of evidences of indebtedness or
assets  (excluding  regular  periodic  cash  dividends or  dividends  payable in
Preferred  Stock)  or of  subscription  rights or  warrants  (other  than  those
referred to above).

         The number of outstanding  Rights is subject to adjustment in the event
of a stock  dividend on the Common  Stock  payable in shares of Common  Stock or
subdivisions,  consolidations or combinations of the Common Stock occurring,  in
any such case, prior to the Distribution Date.

         Shares of Preferred Stock  purchasable upon exercise of the Rights will
not be redeemable.  Each share of Preferred Stock will be entitled, when, as and
if declared,  to a minimum preferential  quarterly dividend payment of $1.00 per
share but will be entitled to an  aggregate  dividend of 1000 times the dividend
declared per share of Common Stock. In the event of liquidation,  dissolution or
winding up of the Company,  the holders of the Preferred  Stock will be entitled
to a minimum

                                       3


preferential  payment  of  $150.00  per  share  (plus  any  accrued  but  unpaid
dividends)  but will be  entitled  to an  aggregate  payment  of 1000  times the
payment made per share of Common Stock.  Each share of Preferred Stock will have
1000 votes, voting together with the Common Stock.  Finally, in the event of any
merger, consolidation or other transaction in which outstanding shares of Common
Stock are converted or exchanged, each share of Preferred Stock will be entitled
to receive  1000  times the amount  received  per share of Common  Stock.  These
rights are protected by customary antidilution provisions.

         Because of the nature of the Preferred  Stock's  dividend,  liquidation
and voting rights,  the value of the one  one-thousandth  interest in a share of
Preferred Stock  purchasable upon exercise of each Right should  approximate the
value of one share of Common Stock.

         In the event  that any  person  or group of  affiliated  or  associated
persons becomes an Acquiring Person,  each holder of a Right,  other than Rights
beneficially  owned by the Acquiring  Person (which will thereupon become void),
will  thereafter  have the right to receive upon exercise of a Right that number
of shares of Common Stock having a market value of two times the exercise  price
of the Right.

         In the event  that,  after a person or group  has  become an  Acquiring
Person,  the  Company  is  acquired  in a merger or other  business  combination
transaction or 50% or more of its consolidated assets or earning power are sold,
proper provisions will be made so that each holder of a Right (other than Rights
beneficially  owned by an  Acquiring  Person  which will have become  void) will
thereafter have the right to receive upon the exercise of a Right that number of
shares of common  stock of the person  with whom the  Company has engaged in the
foregoing  transaction (or its parent) that at the time of such transaction have
a market value of two times the exercise price of the Right.

         At any time after any person or group  becomes an Acquiring  Person and
prior to the earlier of one of the events described in the previous paragraph or
the  acquisition  by such  Acquiring  Person  of 50% or more of the  outstanding
shares  of  Common  Stock,  the  Board of  Directors  of the  Company  (with the
concurrence  of a majority  of the  Continuing  Directors  then in  office)  may
exchange the Rights (other than Rights owned by such Acquiring Person which will
have become void),  in whole or in part, for shares of Common Stock or Preferred
Stock (or a series of the Company's  preferred stock having  equivalent  rights,
preferences and privileges), at an exchange ratio of one share of Common Stock,

                                       4


or a fractional share of Preferred Stock (or other preferred  stock)  equivalent
in value thereto, per Right.

         The Rights Agreement defines "Continuing Director" as any member of the
Company's  Board of Directors who is not an Acquiring  Person or an affiliate or
associate of an Acquiring Person or a  representative  of an Acquiring Person or
any such  affiliate  or  associate  and  either (i) was a member of the Board of
Directors prior to the date of the Rights Agreement or (ii) subsequently becomes
a Board  member,  if such  person's  nomination  for election or election to the
Board is recommended or approved by a majority of the Continuing Directors.

         With certain  exceptions,  no adjustment in the Purchase  Price will be
required until  cumulative  adjustments  require an adjustment of at least 1% in
such Purchase  Price.  No fractional  shares of Preferred  Stock or Common Stock
will be issued  (other than  fractions  of  Preferred  Stock which are  integral
multiples of one  one-thousandths  of a share of Preferred Stock,  which may, at
the election of the Company, be evidenced by depository  receipts),  and in lieu
thereof an adjustment in cash will be made based on the current  market price of
the Preferred Stock or the Common Stock.

         At any time prior to the time an Acquiring  Person  becomes  such,  the
Board of Directors  of the Company  (with the  concurrence  of a majority of the
Continuing  Directors)  may redeem the  Rights in whole,  but not in part,  at a
price of $.01 per Right (the "Redemption  Price").  The redemption of the Rights
may be made  effective at such time,  on such basis and with such  conditions as
the Board of Directors  and the  majority of such  Continuing  Directors  may in
their discretion  establish.  Immediately upon any redemption of the Rights, the
right to exercise the Rights will terminate and the only right of the holders of
Rights will be to receive the Redemption Price.

         For so long as the  Rights  are then  redeemable,  the  Company  may by
majority  vote of the Board of  Directors  and majority  vote of the  Continuing
Directors,  except  with  respect  to the  redemption  price,  amend the  Rights
Agreement in any manner. After the Rights are no longer redeemable,  the Company
may, except with respect to the redemption price,  amend the Rights Agreement in
any  manner  that does not  adversely  affect  the  interests  of holders of the
Rights.

         Until a Right is exercised or exchanged,  the holder thereof,  as such,
will  have  no  rights  as a  stockholder  of the  Company,  including,  without
limitation, the right to vote or to receive dividends.

                                       5



         The Rights  Agreement,  which  includes as Exhibit B the Form of Rights
Certificate,  is  attached  hereto as  Exhibit 1 and is  incorporated  herein by
