(1) The amount of common stock, par value $.01, of the Registrant ("Common
    Stock") to be registered has been determined by multiplying the highest
    possible exchange ratio for such shares in the Merger (0.520231 of a share
    of Common Stock for each share of common stock, par value $.01, of IDB ("IDB
    Common Stock")) by 88,279,487, the maximum number of shares of IDB Common
    Stock estimated to be outstanding on the closing date of the Merger.
 
(2) Estimated pursuant to Rule 457(f)(1) of the Securities Act of 1933, as
    amended (the "Securities Act"), based upon the market value of the shares of
    IDB Common Stock to be cancelled in the Merger ($9.125 per share, which is
    the average of the reported high and low sales prices of a share of IDB
    Common Stock on the Nasdaq National Market on November 18, 1994).
 
(3) Estimated solely for purposes of calculating the registration fee pursuant
    to Rule 457(f)(1) of the Securities Act as follows: 1/29th of one percent of
    (a) $9.125, the average of the reported high and low sales prices of a share
    of IDB Common Stock on the Nasdaq National Market on November 18, 1994,
    multiplied by (b) 88,279,487, the maximum number of shares of IDB Common
    Stock which may be exchanged upon consummation of the Merger (based on the
    assumptions stated in note (1) above).
 
     A fee of $165,459.00 was paid on September 12, 1994 pursuant to Section
     14(g)(1)(A)(i) of the Securities Exchange Act of 1934, as amended (the
     "Exchange Act"), and Rules 14a-6(i)(4) and 0-11 promulgated thereunder
     ("Rule 0-11") in respect of the Merger upon the filing by the Registrant
     and IDB of joint preliminary proxy materials relating thereto. Pursuant to
     Rule 457(b) of the Securities Act, and Rule 0-11 and Section 14(g)(1)(B) of
     the Exchange Act, the amount of the previously paid fee has been credited
     against the registration fee payable in connection with this filing.
     Accordingly, $165,459.00 of the filing fee for this Registration Statement
     has already been paid and the balance of $112,295.00 is required to be paid
     with this Registration Statement.

Dear Shareholder:
 
     The Board of Directors cordially invites you to attend a Special Meeting of
Shareholders of LDDS Communications, Inc. ("LDDS"), to be held at   :   .m.,
local time, on December 29, 1994 at 515 East Amite St., Jackson, Mississippi.
 
     At this important meeting, you will be asked to consider two proposals. The
first is a proposal to approve the issuance of LDDS common stock pursuant to an
Agreement and Plan of Merger dated as of August 1, 1994 (the "Merger Agreement")
by and among LDDS, IDB Communications Group, Inc. ("IDB") and 123 Corp.
("Acquisition Subsidiary"), a wholly owned subsidiary of LDDS. Pursuant to the
Merger Agreement, Acquisition Subsidiary would merge with and into IDB in a
transaction which would result in the survival of IDB as a wholly owned
subsidiary of LDDS (the "Merger"). As a result of the Merger, each share of IDB
common stock would be converted into the right to receive between 0.450867 and
0.520231 of a share of LDDS common stock. The exact fraction of a share of LDDS
common stock into which each share of IDB common stock would be converted (the
"Exchange Ratio") would be determined by reference to the average closing price
of LDDS common stock during the thirty consecutive trading days prior to the
date three business days prior to the day on which the Merger is consummated, as
described in detail in the accompanying Joint Proxy Statement/Prospectus. Based
on an assumed Exchange Ratio of        , an assumed per share market value of
$          per share of LDDS common stock and an assumed number of
shares of IDB common stock outstanding, the stockholders of IDB would receive
LDDS common stock having a market value of $     million in the aggregate, or
$          per share of IDB common stock, in the Merger. No assurance can be
given as to the actual Exchange Ratio that will be utilized in the Merger or the
market price of LDDS common stock.
 
     Management of LDDS believes that the proposed Merger would provide
shareholders of LDDS with the opportunity to participate in the enhanced growth
and other opportunities of the consolidated organization. For information
concerning the reasons the Board of Directors determined to proceed with this
transaction, see "Plan of Merger -- Reasons for the Merger; Board
Recommendations" in the accompanying Joint Proxy Statement/Prospectus.
 
     AT THE DIRECTORS' MEETING HELD TO CONSIDER THE MERGER, THE DIRECTORS OF
LDDS PRESENT CAREFULLY CONSIDERED AND UNANIMOUSLY APPROVED THE TERMS OF THE
MERGER AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY AS BEING FAIR AND IN
THE BEST INTEREST OF LDDS AND ITS SHAREHOLDERS. THE LDDS BOARD OF DIRECTORS
UNANIMOUSLY RECOMMENDS THAT THE SHAREHOLDERS VOTE "FOR" THE PROPOSAL TO APPROVE
THE ISSUANCE OF LDDS COMMON STOCK PURSUANT TO THE MERGER AGREEMENT.
 
     The accompanying Joint Proxy Statement/Prospectus sets forth, or
incorporates by reference, information, including financial data, relating to
LDDS and IDB and describes the terms and conditions of the proposed Merger. The
Board of Directors urges that you carefully review these materials before
completing the enclosed proxy card. LDDS shareholders are not entitled to
dissenters' or appraisal rights in connection with the Merger because LDDS is
not a constituent corporation in the Merger. See "Dissenters' Rights" in the
accompanying Joint Proxy Statement/Prospectus.
 
     The second proposal is to consider and vote upon the LDDS Communications,
Inc. 1995 Special Performance Bonus Plan (the "1995 Plan"), which is described
in the accompanying Joint Proxy Statement/Prospectus under the heading "Item 2.
Approval of the LDDS Communications, Inc. 1995 Special Performance Bonus Plan."
<PAGE>   5
 
     As of the record date for the Special Meeting, directors and executive
officers of LDDS and their affiliates (as a group) were entitled to vote
shares of LDDS common stock and 10,896,785 shares of Series 1 Preferred Stock
(representing        underlying shares of LDDS common stock), or approximately
     % of the outstanding votes entitled to be cast at the Special Meeting. All
such directors and executive officers and their affiliates have indicated their
intention to vote their shares for the approval of the issuance of LDDS common
stock pursuant to the Merger Agreement and for the approval of the 1995 Plan.
 
     Approval by LDDS shareholders of the issuance of LDDS common stock pursuant
to the Merger Agreement is a condition to the consummation of the Merger.
Approval by LDDS shareholders is also a condition to effectiveness of the 1995
Plan. Accordingly, it is important that your shares be represented at the
Special Meeting, whether or not you plan to attend the Special Meeting in
person. Please complete, sign and date the enclosed proxy card and return it in
the accompanying envelope, which requires no postage if mailed within the United
States. If you later decide to attend the Special Meeting and vote in person, or
if you wish to revoke your proxy for any reason prior to the vote at the Special
Meeting, you may do so and your proxy will have no further effect. Any
shareholder returning a blank executed proxy card will be authorizing the named
proxies to vote the shares covered by the proxy in favor of the issuance of LDDS
common stock pursuant to the Merger Agreement and in favor of the proposal to
approve the 1995 Plan.
 
     Should you require assistance in completing your proxy card or if you have
questions about the voting procedure described in the accompanying Joint Proxy
Statement/Prospectus, please feel free to contact Investor Relations at LDDS at
515 East Amite Street, Jackson, Mississippi 39201-2702 (telephone (601)
360-8600).

TO THE SHAREHOLDERS OF LDDS COMMUNICATIONS, INC.:
 
     Notice is hereby given that a Special Meeting of Shareholders of LDDS
Communications, Inc. ("LDDS") will be held at 515 East Amite St., Jackson,
Mississippi, on December 29, 1994 at   :   .m., local time, for the following
purposes:
 
          (1) To consider and vote upon a proposal to approve the issuance of
     LDDS common stock pursuant to the Agreement and Plan of Merger dated as of
     August 1, 1994 (the "Merger Agreement") by and among LDDS, IDB
     Communications Group, Inc. ("IDB") and 123 Corp. ("Acquisition
     Subsidiary"), a wholly owned subsidiary of LDDS. Pursuant to the Merger
     Agreement, Acquisition Subsidiary would merge with and into IDB in a
     transaction which would result in the survival of IDB as a wholly owned
     subsidiary of LDDS. As a result of this merger, each share of IDB common
     stock would be converted into the right to receive a certain fraction of a
     share of LDDS common stock. The Merger Agreement provides that IDB
     stockholders will receive a minimum of 0.450867 of a share of LDDS common
     stock for each share of IDB common stock if LDDS shares are valued at $22
     or more; or a maximum of 0.520231 of a share of LDDS common stock for each
     share of IDB common stock if LDDS shares are valued at $16 or less. Within
     that range, the exchange ratio increases or decreases by 0.001445 of a
     share of LDDS common stock for every $0.125 decrease or increase,
     respectively, in LDDS share value between $22 and $16. The exact fraction
     of a share of LDDS common stock into which each share of IDB common stock
     would be converted would be determined by reference to the average closing
     price of LDDS common stock during the thirty consecutive trading days prior
     to the date three business days prior to the day on which the merger is
     consummated, as described in detail in the accompanying Joint Proxy
     Statement/Prospectus;
 
          (2) To consider and to vote upon a proposal to adopt the LDDS
     Communications, Inc. 1995 Special Performance Bonus Plan; and
 
          (3) To transact such other business as may properly come before the
     Special Meeting or any adjournment thereof.
 
     The Board of Directors has fixed the close of business on November 23,
1994, as the record date for determining the shareholders entitled to receive
notice of, and to vote at, the Special Meeting or any adjournment or
postponement thereof.

Dear Stockholder:
 
     The Board of Directors cordially invites you to attend a Special Meeting of
Stockholders of IDB Communications Group, Inc. ("IDB"), to be held at   :   .m.,
local time, on December 29, 1994 at 515 East Amite St., Jackson, Mississippi.
 
     At this important meeting, you will be asked to consider a proposal to
approve the Agreement and Plan of Merger dated as of August 1, 1994 (the "Merger
Agreement") by and among IDB, LDDS Communications, Inc. ("LDDS") and 123 Corp.
("Acquisition Subsidiary"), a wholly owned subsidiary of LDDS, and the
transactions contemplated thereby. Pursuant to the Merger Agreement, Acquisition
Subsidiary would merge with and into IDB in a transaction which would result in
the survival of IDB as a wholly owned subsidiary of LDDS (the "Merger"). As a
result of the Merger, each share of IDB common stock would be converted into the
right to receive approximately one-half of a share of LDDS common stock. The
exact fraction of a share of LDDS common stock into which each share of IDB
common stock would be converted (the "Exchange Ratio") would be determined by
reference to the average closing price of LDDS common stock during the thirty
consecutive trading days prior to the date three business days prior to the day
on which the Merger is consummated, as described in detail in the accompanying
Joint Proxy Statement/Prospectus. Based on an assumed Exchange Ratio of
          , an assumed per share market value of $          per share of LDDS
common stock and an assumed number of           shares of IDB common stock
outstanding, the stockholders of IDB would receive LDDS common stock having a
market value of $          million in the aggregate, or $          per share of
IDB common stock, in the Merger. No assurance can be given as to the actual
Exchange Ratio that will be utilized in the Merger or the market price of LDDS
common stock.
 
     Also described in the accompanying Joint Proxy Statement/Prospectus is
LDDS's proposed acquisition of Williams Telecommunications Group, Inc.
("WilTel") for $2.5 billion in cash (the "WilTel Acquisition"). At the Special
Meeting, you will be asked to approve the Merger whether or not the WilTel
Acquisition occurs. If the WilTel Acquisition is consummated, the information
contained and incorporated in the Joint Proxy Statement/Prospectus concerning
WilTel will be important to your decision with respect to the Merger and should
be carefully considered.
 
     Management of IDB believes that, whether or not the WilTel Acquisition is
consummated, the proposed Merger would provide holders of IDB common stock with
the opportunity to participate in the enhanced growth and other opportunities of
the consolidated organization. For information concerning the reasons the Board
of Directors determined to proceed with this transaction, see "Plan of
Merger -- Reasons for the Merger; Board Recommendations" in the accompanying
Joint Proxy Statement/Prospectus.
 
     AT THE DIRECTORS' MEETINGS HELD TO CONSIDER THE MERGER, THE DIRECTORS OF
IDB CAREFULLY CONSIDERED AND UNANIMOUSLY APPROVED THE TERMS OF THE MERGER AND
THE TRANSACTIONS CONTEMPLATED THEREBY AS BEING FAIR AND IN THE BEST INTERESTS OF
IDB AND ITS STOCKHOLDERS, WHETHER OR NOT THE WILTEL ACQUISITION IS CONSUMMATED.
THE IDB BOARD OF DIRECTORS UNANIMOUSLY
<PAGE>   8
 
RECOMMENDS THAT THE STOCKHOLDERS VOTE "FOR" THE PROPOSAL TO APPROVE THE MERGER
AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY. IF SO APPROVED, THE MERGER
MAY BE EFFECTED WITHOUT REGARD TO WHETHER THE WILTEL ACQUISITION IS CONSUMMATED.
 
     The accompanying Joint Proxy Statement/Prospectus sets forth, or
incorporates by reference, information, including financial data, relating to
IDB, LDDS and WilTel and describes the terms and conditions of the proposed
Merger. The Board of Directors urges that the stockholders carefully review
these materials before completing the enclosed proxy card. Pursuant to Section
262(b) of the Delaware General Corporation Law, IDB stockholders are not
entitled to dissenters' or appraisal rights in connection with the Merger. See
"Dissenters' Rights" in the accompanying Joint Proxy Statement/Prospectus.
 
     As of the record date for the Special Meeting, all directors of IDB (as a
group) were entitled to vote 5,180,423 shares of IDB common stock, or
approximately      % of the outstanding shares entitled to vote at the Special
Meeting. All such directors have indicated their intention to vote their shares
for the approval of the Merger Agreement and the transactions contemplated
thereby at the Special Meeting.
 
     Approval of the Merger Agreement and the transactions contemplated thereby
by IDB stockholders is a condition to the consummation of the Merger.
Accordingly, it is important that your shares be represented at the Special
Meeting, whether or not you plan to attend the Special Meeting in person. Please
complete, sign and date the enclosed proxy card and return it in the
accompanying envelope, which requires no postage if mailed within the United
States. If you later decide to attend the Special Meeting and vote in person, or
if you wish to revoke your proxy for any reason prior to the vote at the Special
Meeting, you may do so and your proxy will have no further effect. Any
stockholder returning a blank executed proxy card will be authorizing the named
proxies to vote the shares covered by the proxy in favor of the Merger Agreement
and the transactions contemplated thereby.
 
     Please DO NOT send in your stock certificates with your proxy card. You
should not send in your stock certificates until you receive a transmittal
letter, which will only be sent after the effective time of the Merger.
 
     Should you require assistance in completing your proxy card or if you have
questions about the voting procedure described in the accompanying Joint Proxy
Statement/Prospectus, please feel free to contact IDB Communications Group,
Inc., 10525 West Washington Boulevard, Culver City, California 90232-1922,

TO THE STOCKHOLDERS OF IDB COMMUNICATIONS GROUP, INC.:
 
     Notice is hereby given that a Special Meeting of Stockholders of IDB
Communications Group, Inc. ("IDB") will be held at 515 East Amite St., Jackson,
Mississippi, on December 29, 1994 at   :   .m., local time, for the following
purposes:
 
          (1) To consider and vote upon a proposal to approve the Agreement and
     Plan of Merger, dated as of August 1, 1994 (the "Merger Agreement"), by and
     among IDB, LDDS Communications, Inc. ("LDDS") and 123 Corp. ("Acquisition
     Subsidiary"), a wholly owned subsidiary of LDDS, and the transactions
     contemplated thereby. Pursuant to the Merger Agreement, Acquisition
     Subsidiary would merge with and into IDB in a transaction which would
     result in the survival of IDB as a wholly owned subsidiary of LDDS. As a
     result of this merger, each share of IDB common stock would be converted
     into the right to receive approximately one-half of a share of LDDS common
     stock. The Merger Agreement provides that IDB stockholders will receive a
     minimum of 0.450867 of a share of LDDS common stock for each share of IDB
     common stock if LDDS shares are valued at $22 or more; or a maximum of
     0.520231 of a share of LDDS common stock for each share of IDB common stock
     if LDDS shares are valued at $16 or less. Within that range, the exchange
     ratio increases or decreases by 0.001445 of a share of LDDS common stock
     for every $0.125 decrease or increase, respectively, in LDDS share value
     between $22 and $16. The exact fraction of a share of LDDS common stock
     into which each share of IDB common stock would be converted would be
     determined by reference to the average closing price of LDDS common stock
     during the thirty consecutive trading days prior to the date three business
     days prior to the day on which the merger is consummated, as described in
     detail in the accompanying Joint Proxy Statement/Prospectus; and

1994, as the record date for determining the stockholders entitled to receive
notice of, and to vote at, the Special Meeting or any adjournment or

           JOINT PROXY STATEMENT FOR SPECIAL MEETINGS OF SHAREHOLDERS
                        TO BE HELD ON DECEMBER 29, 1994.
                            ------------------------
 
                    PROSPECTUS OF LDDS COMMUNICATIONS, INC.
 
                 A MAXIMUM OF 45,925,726 SHARES OF COMMON STOCK
                                 $.01 PAR VALUE
                            ------------------------
 
    LDDS Communications, Inc., a Georgia corporation ("LDDS"), has filed a
registration statement pursuant to the Securities Act of 1933, as amended,
covering a maximum of 45,925,726 shares of LDDS's common stock, $.01 par value
per share ("LDDS Common Stock"), which may be issued in connection with the
proposed merger (the "Merger") of 123 Corp., a Delaware corporation wholly owned
by LDDS ("Acquisition Subsidiary"), with and into IDB Communications Group,
Inc., a Delaware corporation ("IDB"), with IDB being the surviving corporation.
Certain matters relating to the Merger will be submitted to votes of the
respective shareholders of LDDS and IDB at special meetings to be held on
December 29, 1994 (the "LDDS Special Meeting" and the "IDB Special Meeting") for
which this document serves as a Joint Proxy Statement in connection with the
solicitation of proxies by the respective Boards of Directors of LDDS and IDB
for use at such special meetings and at any adjournments or postponements
thereof. LDDS shareholders will also be asked to consider and vote upon a
proposal to approve the LDDS Communications, Inc. 1995 Special Performance Bonus
Plan (the "1995 Plan"). See "The LDDS Special Meeting" and "The IDB Special
Meeting." This document also constitutes a Prospectus of LDDS with respect to
the shares of LDDS Common Stock (the "LDDS Shares") to be issued, if the Merger
is consummated, to holders of IDB's common stock, $.01 par value per share (the
"IDB Common Stock").

    On the effective date of the Merger, each outstanding share of IDB Common
Stock will be converted into the right to receive between 0.450867 and 0.520231
of a share of LDDS Common Stock, depending on the average closing trade price of
LDDS Common Stock for the thirty consecutive trading days prior to the date
three business days prior to the Closing Date (as hereinafter defined) of the
Merger (the "Share Value"). The fractional amount of a share of LDDS Common
Stock into which each share of IDB Common Stock (the "IDB Shares") will be
converted is referred to herein as the "Exchange Ratio." If the Share Value is
equal to or less than $16.00, the Exchange Ratio will be 0.520231. If the Share
Value is equal to or greater than $22.00, the Exchange Ratio will be 0.450867.
If the Share Value is greater than $16.00 but less than $22.00, the Exchange
Ratio increases or decreases by 0.001445 of an LDDS Share for each $0.125
decrease or increase, respectively, in the Share Value, as more fully set forth
in Section 1.3 of the Merger Agreement (provided that if the Share Value falls
between any two of the Share Values, the Exchange Ratio shall be that applicable
to the lower of the two Share Values). For more information regarding the
calculation and range of possible Exchange Ratios, see "Plan of
Merger -- General Description of the Merger." Fractional shares of LDDS Common
Stock will not be issued; instead, IDB stockholders who would otherwise be
entitled to fractional shares of LDDS Common Stock will receive cash in lieu
thereof. See "Plan of Merger -- Fractional Shares."

    Each holder of an unexercised option (an "IDB Option") exercisable for
shares of IDB Common Stock will be entitled to receive an option exercisable for
LDDS Common Stock having the same terms and conditions as the IDB Option, except
that the exercise price and the number of shares of LDDS Common Stock issuable
upon exercise shall be divided and multiplied, respectively, by the Exchange
Ratio. The 5% Convertible Subordinated Notes due 2003 issued by IDB (the "IDB
Notes") will become convertible into shares of LDDS Common Stock, with a
proportional adjustment being made to the conversion price of the IDB Notes to
reflect the Exchange Ratio. See "Plan of Merger -- General Description of the
Merger."

    The Merger is intended to qualify as a reorganization under the Internal
Revenue Code of 1986, as amended. No gain or loss will be recognized by IDB
stockholders on the exchange of their IDB Shares for LDDS Shares except to the
extent of cash payments received in lieu of fractional LDDS Shares. See "Plan of
Merger -- Certain Federal Income Tax Consequences."

    LDDS Common Stock is traded in the over-the-counter market and its
quotations are reported on the Nasdaq National Market under the symbol "LDDS."
IDB Common Stock is also traded in the over-the-counter market and its
quotations are reported on the Nasdaq National Market under the symbol "IDBX."
On November   , 1994, the closing sale prices for LDDS Common Stock and IDB
Common Stock, as reported on the Nasdaq National Market, were $         per
share and $         per share, respectively.

    LDDS recently entered into an agreement with The Williams Companies, Inc.
("Williams") to acquire Williams' subsidiary, Williams Telecommunications Group,
Inc. ("WilTel"), for $2.5 billion in cash, subject to adjustment (the "WilTel
Acquisition"). The Merger may be effected without regard to whether the WilTel
Acquisition is consummated. See "Information Regarding LDDS -- Recent
Developments."

                              SUMMARY INFORMATION
 
     The following is a summary of certain important terms of the proposed
Merger and related information discussed elsewhere in this Joint Proxy
Statement/Prospectus. This summary does not purport to be complete and is
qualified in its entirety by reference to the more detailed information included
in this Joint Proxy Statement/Prospectus and the appendices hereto, including,
but not limited to, the Agreement and Plan of Merger set forth as Appendix A
hereto. Special Meetings (the "Special Meetings") of the respective shareholders
of LDDS and IDB have been called for December 29, 1994, for the purpose of
voting on, in the case of LDDS, a proposal to approve the issuance of LDDS
Common Stock pursuant to the Agreement and Plan of Merger dated August 1, 1994
(the "Merger Agreement") by and among LDDS, Acquisition Subsidiary and IDB, and,
in the case of IDB, a proposal to approve the Merger Agreement and the
transactions contemplated thereby. LDDS shareholders will also be asked to
consider and vote upon a proposal to approve the 1995 Plan. See "The LDDS
Special Meeting" and "The IDB Special Meeting." Shareholders of each of LDDS and
IDB are urged to read this Joint Proxy Statement/Prospectus and the appendices
hereto in their entirety and to consider carefully the information set forth
under the heading "Risk Factors."
 
BUSINESS OF LDDS
 
     LDDS is the fourth largest long distance telecommunications company in the
United States, based on 1993 revenues. The company provides long distance
telecommunications services through its digital fiber optic and digital
microwave network to business and residential customers, with service to points
throughout the nation and to more than 220 foreign countries. The products and
services provided by LDDS include: switched and dedicated long distance
products, 800 services, calling cards, operator services, private lines, frame
relays, debit cards, conference calling services, advanced billing systems and
broadcast fax services. Based on Federal Communications Commission ("FCC")
statistics as of December 31, 1993 (the most recent statistics available),
LDDS's share of total toll service revenues for 1993 was 1.5%.
 
     LDDS was organized in 1983. Its operations have grown as a result of
management's emphasis on a four-point growth strategy, which includes internal
growth, the selective acquisition of smaller long distance companies with
limited geographic service areas and market shares, the consolidation of certain
third tier long distance carriers with larger market shares, and international
expansion. On September 15, 1993, a three-way merger occurred whereby (i) MCC
merged with and into Resurgens and (ii) LDDS Communications, Inc., a Tennessee
corporation ("LDDS-TN"), merged with and into Resurgens (the "Prior Mergers").
 
     At the time of the Prior Mergers, the name of Resurgens, the legal
survivor, was changed to LDDS Communications, Inc. and the separate corporate
existences of LDDS-TN and MCC terminated. For accounting purposes, however,
LDDS-TN was the survivor because the former shareholders of LDDS-TN acquired
majority ownership of LDDS. Accordingly, unless otherwise indicated, all
historical information presented herein reflects the operations of LDDS-TN.
 
     As of             , 1994, there were           shares of LDDS Common Stock
and 12,896,785 shares of LDDS preferred stock outstanding. For the fiscal year
ended December 31, 1993, LDDS reported revenues of $1.14 billion, net income of
$104.2 million and net income applicable to common shareholders of $93.7
million. For the nine months ended September 30, 1994, LDDS reported revenues of
$1.3 billion, net income of $118.7 million and net income applicable to common
shareholders of $97.8 million. For pro forma, post-Merger financial information
regarding LDDS (with and without giving effect to the WilTel Acquisition) and
IDB, see "-- Recent Developments Regarding LDDS," "Pro Forma Combining Financial
Statements" and "Management's Discussion and Analysis of the Pro Forma Combining
Financial Statements."
 
     LDDS's principal executive offices are located at 515 East Amite Street,
Jackson, Mississippi 39201-2702 and its telephone number is (601) 360-8600. See
"Information Regarding LDDS."
 
RECENT DEVELOPMENTS REGARDING LDDS
 
     On August 22, 1994, LDDS announced that it had signed a definitive
agreement with Williams to acquire Williams' subsidiary, WilTel, for $2.5
billion in cash, subject to adjustment (the "WilTel Acquisition").
 
                                        8

WilTel, through its subsidiaries, is a full service telecommunications company
providing data and voice transmission services worldwide. WilTel operates
approximately 11,000 miles of fiber optic cable and digital microwave facilities
and has access to approximately 40,000 miles of additional digital transmission
network facilities through network sharing and lease agreements with other
carriers. Operations of WilTel also include domestic and international private
line and switched long distance services.
 
     The following table sets forth, for the periods indicated, certain summary
pro forma financial information for LDDS, assuming the WilTel Acquisition (and
the proposed financing thereof) and the Merger had occurred as of January 1,
1993 (in thousands, except per share data). The following pro forma information
should be read in conjunction with the historical consolidated financial
statements of LDDS, IDB and the network services operations of WilTel and the
related notes thereto, which are incorporated by reference herein, and the LDDS
Adjusted Historical Financial Statements and the IDB Adjusted Historical
Financial Statements and the related notes thereto, which are set forth
elsewhere herein. See "Available Information," "Incorporation by Reference,"
"Pro Forma Combining Financial Statements" and "Management's Discussion and
Analysis of the Pro Forma Combining Financial Statements." The following
information is presented for comparative purposes only and is not intended to be
indicative of actual results had the transactions occurred as of the date
indicated above nor do they purport to indicate results which may be attained in
the future.

</TABLE>
 
     As of September 30, 1994, the pro forma balance sheet of LDDS, which
assumes the WilTel Acquisition (and the proposed financing thereof) and the
Merger had occurred as of January 1, 1993, includes total assets of $6.4
billion, long-term debt of $3.4 billion, and shareholders' investment of $1.9
billion.
 
     The WilTel Acquisition, which is expected to close on or before February 1,
1995, is subject to, among other things, approvals by the FCC and various state
public utility or service agencies ("PUCs"). The waiting period for the WilTel
Acquisition under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the
"Hart-Scott-Rodino Act") was terminated on September 28, 1994. LDDS and IDB
shareholders will not be asked to approve the WilTel Acquisition. The WilTel
Acquisition is not a condition to the consummation of the Merger, and there can
be no assurance that the WilTel Acquisition will be consummated.
 
     LDDS has obtained underwritten commitments for loan facilities aggregating
$3.41 billion both to finance the WilTel Acquisition and refinance LDDS's
existing credit facilities. The commitments would be funded through a $2.16
billion, six-year reducing revolving credit facility ("Facility A") and a $1.25
billion, two-year term facility ("Facility B"). Principal payments under
Facility A would commence in varying quarterly amounts on September 30, 1996
with the final installment due on December 31, 2000. Facility B would mature in
a single installment on December 31, 1996. Facility A and Facility B would bear
interest at one of several interest rate options, payable quarterly, similar to
those in effect under LDDS's existing credit facilities. The facilities would be
unsecured and require compliance with certain financial and other operating
covenants. The facilities would also be subject to an annual commitment fee not
to exceed 0.375% of any unborrowed portion of Facility A and Facility B.

<PAGE>   20
 
     Borrowings under LDDS's existing and proposed bank credit facilities bear
interest at rates that fluctuate with prevailing short-term interest rates.
Increases in interest rates on these obligations would have an adverse effect
upon LDDS's reported net income and cash flow. In addition, these credit
facilities restrict the payment of dividends and otherwise limit LDDS's
financial flexibility. Management of LDDS believes that the combined operations
of LDDS, IDB and WilTel would generate sufficient cash flow to service LDDS's
debt under the proposed bank credit facilities upon consummation of the proposed
WilTel Acquisition; however, economic downturns, increased interest rates and
other adverse developments, including factors beyond LDDS's control, could
impair its ability to service the resulting indebtedness. In addition, the cash
flow required to service LDDS's debt would reduce its liquidity, which in turn
may reduce its ability to fund internal growth, additional acquisitions and
capital improvements. See "Risk Factors -- Risks of Increased Financial
Leverage; Debt Service, Interest Rate Fluctuations, Possible Reduction in
Liquidity, Dividend Restrictions, and Other Restrictive Covenants."
 
     LDDS anticipates it will need to refinance Facility B, which would require
LDDS to seek other financing alternatives such as public or private debt or
equity offerings, or refinancing with the existing or new lenders, although, to
the extent available, Facility A may be used to refinance Facility B. No
assurance can be given that any such refinancing would be available on terms
reasonably acceptable to LDDS. See "Information Regarding LDDS -- Recent
Developments" and "Management's Discussion and Analysis of the Pro Forma
Combining Financial Statements."
 
BUSINESS OF IDB
 
     IDB operates a domestic and international communications network providing
international private line and public switched long distance telephone services,
facsimile and data connections, television and radio transmission services and
mobile satellite communications capabilities. IDB was established in 1983 to
provide transmission of sporting and music events to radio stations nationally.
Aided by the AT&T divestitures in 1984 and the opening of international
telecommunications markets, IDB has become a full service provider of
international telecommunications services as well as specialized broadcasting
services. IDB has expanded rapidly through the growth of its existing businesses
as well as through the selective acquisition of complementary companies which
have provided strategic facilities, international operating agreements and
customers. IDB operates through four service units: IDB WorldCom, IDB Broadcast,
IDB Mobile and IDB Systems. Based on FCC statistics as of December 31, 1992 (the
most recent international statistics available), on a combined IDB, World
Communications, Inc. ("WorldCom") and TRT Communications, Inc. ("TRT") basis,
IDB's share of total net revenues from U.S.-based international long distance
communications services in 1992 was 2.2%.
 
     As of November 2, 1994, there were 74,456,003 shares of IDB Common Stock
and no shares of preferred stock outstanding. For the fiscal year ended December
31, 1993, IDB reported revenues of $339.4 million, income before preferred stock
dividend of $12.2 million and net income available to common stockholders of
$11.0 million. For the nine months ended September 30, 1994, IDB reported
revenues of $378.1 million and a net loss of $170.5 million.
 
     IDB's principal executive offices are located at 10525 West Washington
Boulevard, Culver City, California 90232-1922 and its telephone number is (213)
870-9000. See "Information Regarding IDB."
 
RECENT DEVELOPMENTS REGARDING IDB
 
     RESIGNATION OF INDEPENDENT AUDITORS.  On May 23, 1994, Deloitte & Touche
LLP ("Deloitte") resigned as IDB's independent auditors. Deloitte has stated it
resigned as a result of events surrounding the release and reporting of IDB's
financial results for the first quarter of 1994. In submitting its resignation,
Deloitte informed IDB management and the Audit Committee of the IDB Board of
Directors that there had been a serious breakdown in IDB's process of
identifying, analyzing and recording IDB's business transactions which
prohibited Deloitte from the satisfactory completion of a quarterly review, and
that Deloitte was no longer willing to rely on IDB management's representations
regarding IDB's interim financial statements. IDB announced Deloitte's
resignation on May 31, 1994. On June 24, 1994, upon the recommendation of the
 
                                       10
<PAGE>   21

independent members of IDB's Audit Committee, IDB retained Arthur Andersen LLP
as its new independent auditors. On August 22, 1994, IDB filed Amendment No. 1
on Form 10-Q/A restating its 1994 first quarter results in order to eliminate
previously recorded items, which items were among those as to which Deloitte had
expressed disagreement.
 
     STOCKHOLDER LITIGATION.  Between June 1, 1994 and June 6, 1994, 22 class
action complaints were filed in the U.S. District Court for the Central District
of California on behalf of persons who purchased IDB Common Stock and IDB Notes
against IDB and the current directors and certain officers of IDB and other
parties. In addition, a class action complaint (Hassani v. IDB Communications
Group, Inc.) has been filed in California state court against IDB, its current
directors, certain of its executive officers and Deloitte alleging state law
violations. The complaints allege violations of federal and state securities
laws for disseminating allegedly false and misleading statements concerning
IDB's earnings and accounting practices. Stockholder derivative actions have
also been filed in federal court in California and the Delaware Chancery Court
(Steele v. Sudikoff, et al). The District Court has ordered the 22 class action
complaints and the California derivative action consolidated as one action
styled In re IDB Communications Group, Inc. Securities Litigation. A
consolidated and amended complaint was filed in the District Court on November
18, 1994.
 
     On November 18, 1994, IDB, LDDS and representatives of the plaintiffs in
the foregoing litigation entered into a Stipulation of Settlement (the
"Stipulation"). The Stipulation provides that all claims that were or could have
been asserted by the plaintiffs against IDB or any of the other defendants in
the consolidated action, or on behalf of or by IDB against IDB directors and
officers will, subject to the fulfillment of certain conditions precedent and
the approval of the court, be settled and released and the litigation dismissed
in its entirety with prejudice in exchange for payments totalling $75.0 million.
The conditions precedent to the settlement include completion of the Merger,
timely payment of settlement funds to the escrow agents for the class action and
derivative action plaintiffs, and dismissal of the Delaware Chancery Court
derivative action and California state court class action. The Stipulation
terminates automatically in the event that Court approval is not obtained or any
of the other conditions precedent listed in the Stipulation do not occur, unless
counsel for the class action and derivative action plaintiffs and counsel for
IDB and LDDS mutually agree in writing to proceed with the Stipulation.
Consequently, there can be no assurance that the litigation will be settled and
dismissed on the terms described herein or at all.
 
     INVESTIGATIONS AND OTHER PROCEEDINGS.  On June 9, 1994, the Commission
issued a formal order of investigation concerning certain matters, including
IDB's financial position, books and records and internal controls and trading in
IDB securities on the basis of non-public information. The National Association
of Securities Dealers, Inc. (the "NASD") and other self-regulatory bodies have
also made inquiries of IDB concerning similar matters.
 
     In October, 1994, the U.S. Attorney's Office for the Central District of
California issued grand jury subpoenas to IDB seeking documents relating to
IDB's first quarter results and the Deloitte resignation. IDB has been informed
that a criminal investigation has commenced and is cooperating with the U.S.
Attorney's Office.
 
     OTHER LITIGATION.  On August 20, 1994, Synergistic Technologies, Inc.
("SynTech") filed a complaint in the U.S. District Court for the District of
Columbia alleging that IDB Mobile is infringing upon SynTech's copyrights in
certain computer software. On September 7, 1994, IDB Mobile filed counterclaims
against SynTech for, among other things, breach of contract and interference
with IDB Mobile's contracts with its customers. Both parties filed motions for
summary judgment, which were heard on November 16, 1994. The parties are
awaiting the court's ruling regarding their respective motions for summary
judgment.
 
     On October 12, 1994, Community Network Services, Inc., a reseller of local
and long distance telephone service in New York, filed a complaint in the U.S.
District Court for the Southern District of New York alleging breach of
contract, false advertising under the Lanham Act and a violation of the
Racketeering and Corrupt Organization Act (RICO) based on IDB's termination of
service to the plaintiff.
 
                                       11
<PAGE>   22
 
     On October 21, 1993, Euronet Digital Communications (1992) Ltd.
("Euronet"), Income Advanced Communications Systems Ltd. ("Incom"), Benjamin
Lebovitz and Eli Lior filed a complaint in the U.S. District Court for the
Southern District of New York against IDB and certain IDB personnel, alleging
that IDB breached an oral agreement to enter into a joint venture with Euronet
and that the employee defendants committed fraud by failing to disclose that IDB
had entered into a similar joint venture with a competitor of Euronet. The
plaintiffs also allege that IDB breached separate agency and sales
representative agreements and seek compensatory and punitive damages and
injunctive relief.
                            ------------------------
 
     IDB is unable at this time to predict the outcome of any of the foregoing
litigation, investigations or other proceedings. However, if determined
adversely to IDB, the impact of such matters on the financial position and
results of operations of IDB or, if the Merger is consummated, the consolidated
organization, could be material.
 
     RESTATED AND RECENT FINANCIAL RESULTS.  On August 1, 1994, IDB announced
that it would restate its reported financial results for the quarter ended March
31, 1994. The restatement eliminated approximately $6 million of pre-tax income,
approximately $5 million of which related to a sale of transponder capacity and
approximately $1 million of which related to purchase accounting adjustments. On
November 21, 1994, IDB filed Form 10-Q/A amendments to its reported first and
second quarter financial results making the previously announced changes and
reflecting the effect of IDB's method of accounting for international long
distance traffic, thereby reducing its first quarter net income from $0.12 per
share, as originally reported, to $0.05 per share and, when combined with
adjustments for income tax effects, increasing its second quarter net loss from
$0.20 per share, as originally reported, to $0.27 per share.
 
     For its third quarter ended September 30, 1994, IDB reported a net loss,
after income taxes, of $154.7 million or $2.08 per share on revenues of $131
million. For the nine months ended September 30, 1994, IDB reported a net loss,
after income taxes, of $170.5 million or $2.31 per share on revenues of $378.1
million. Operating results in the third quarter of 1994 were significantly
affected by a stockholder litigation provision of $76.0 million, a reduction in
carrying value of certain IDB Broadcast assets of $35.0 million and a valuation
reserve of $18.3 million provided against deferred tax assets. The pre-tax loss
in the third quarter also reflects significant one time expenses of
approximately $2.0 million related to the Merger, and approximately $2.5 million
in accounting and legal expenses incurred in connection with the resignation of
Deloitte and the ensuing litigation. IDB also accrued approximately $2.4 million
for various non-income tax and related matters in the third quarter. See
"Available Information," "Incorporation by Reference," "Pro Forma Combining
Financial Statements" and "Management's Discussion and Analysis of the Pro Forma
Combining Financial Statements."
 
     As a result of these losses incurred by IDB in the third quarter, IDB is in
default with respect to certain covenants not relating to payment under its line
of credit with Bank of America National Trust and Savings Association ("Bank of
America"). IDB is currently negotiating with Bank of America to obtain a waiver
of such default. There can be no assurance that any such waiver will be
obtained.
 
     RECENT EVENTS CONCERNING THE IDB BROADCAST UNIT.  On November 11, 1994, IDB
and Keystone Communications Corporation, a privately-held provider of broadcast
distribution services ("Keystone"), entered into non-binding letters of intent
regarding a series of transactions which, if consummated, will allow Keystone to
operate and manage the broadcast business of IDB (excluding the simulcast and
audio portions of the business) (the "Broadcast Business"). The letters of
intent provide that Keystone will lease substantially all of the tangible assets
of the Broadcast Business pursuant to an operating lease and will manage the
contracts and other intangible assets of the Broadcast Business through a
management agreement. In connection with these transactions, it is contemplated
that IDB will also acquire for $6.0 million a 25% equity interest in Keystone to
be held through a new partnership formed with other Keystone investors.
 
     On September 23, 1994, IDB entered into a letter agreement with Autotote
Corporation a publicly-held provider of computerized wagering systems
("Autotote"), providing for the sale by IDB of the simulcast assets of its
broadcast business to Autotote for $13.5 million and the sublease by IDB of
certain satellite transmission capacity to Autotote on an ongoing basis. The
simulcast assets consist primarily of transportable broadcast equipment used for
the live transmission of sporting events via satellite in connection with
wagering.
 
                                       12
<PAGE>   23
 
     Consummation of these transactions will be subject to the negotiation of
definitive agreements and receipt of board and various third party approvals.
There can be no assurance that any of these transactions will be consummated or,
if consummated, that they will be on the terms described above.
 
     See "Risk Factors -- Factors Concerning IDB -- Resignation of Independent
Auditors," "-- Stockholder Litigation," "-- Investigations and Other
Proceedings," "-- Other Litigation," "-- Restated and Recent Financial Results,"

Contingency," "Information Regarding IDB -- Recent Developments," "Pro Forma
Combining Financial Statements" and "Management's Discussion and Analysis of the
Pro Forma Combining Financial Statements."
 
THE PROPOSED MERGER
 
     Subject to the satisfaction of the terms and conditions set forth in the
Merger Agreement described below, Acquisition Subsidiary, a wholly owned
subsidiary of LDDS, will merge with and into IDB. Upon consummation of the
Merger, Acquisition Subsidiary's corporate existence will terminate and IDB will
continue as the surviving corporation (the "Surviving Corporation"), wholly
owned by LDDS.
 
     On the effective date of the Merger, except as described herein, each
outstanding IDB Share will be converted into the right to receive a certain
fraction of a share of LDDS Common Stock, depending on the average closing trade
price of LDDS Common Stock for the thirty consecutive trading days prior to date
three business days prior to the Closing Date (as hereinafter defined) of the
Merger. The fractional amount of a share of LDDS Common Stock into which each
IDB Share will be converted is referred to herein as the "Exchange Ratio." If
the Share Value is equal to or less than $16.00, the Exchange Ratio will be
0.520231. If the Share Value is equal to or greater than $22.00, the Exchange
Ratio will be 0.450867. If the Share Value is greater than $16.00 but less than
$22.00, the Exchange Ratio increases or decreases by 0.001445 of an LDDS Share
for each $0.125 decrease or increase, respectively, in the Share Value as more
fully set forth in Section 1.3 of the Merger Agreement (provided that if the
Share Value falls between any two of the Share Values listed therein, the
Exchange Ratio shall be that applicable to the lower of the two Share Values).
Fractional shares of LDDS Common Stock will not be issued; instead, IDB
stockholders who would otherwise be entitled to fractional shares of LDDS Common
Stock will receive cash in lieu thereof. See "Plan of Merger -- General
Description of the Merger" and "-- Fractional Shares."
 
     Based on the capitalization of LDDS and IDB as of                , 1994,
the stockholders of IDB immediately prior to the consummation of the Merger will
own securities representing from approximately 19.5% to 21.8% of the outstanding
LDDS Common Stock on a fully diluted basis following consummation of the Merger,
based on the minimum and maximum Exchange Ratios, respectively.
 
     Each holder of an IDB Option exercisable for shares of IDB Common Stock
will be entitled to receive an option exercisable for LDDS Common Stock having
the same terms and conditions as the IDB Option except that the exercise price
and number of shares of LDDS Common Stock issuable upon exercise shall be
divided and multiplied, respectively, by the Exchange Ratio. The IDB Notes will
become convertible into shares of LDDS Common Stock, with a proportional
adjustment being made to the conversion price of the IDB Notes to reflect the
Exchange Ratio. See "Plan of Merger -- General Description of the Merger" and
"-- Effect of Merger on IDB Notes."
 
     The Merger Agreement provides that the consummation of the Merger is
subject to certain terms and conditions, including the receipt of (i) the
requisite approval of certain matters relating to the Merger by the shareholders
of LDDS and IDB; (ii) the written opinion of Arthur Andersen LLP, the
independent auditors to both LDDS and IDB, to the effect that the Merger will
qualify for pooling of interests accounting treatment; (iii) the written opinion
of IDB's counsel that, except for cash received in lieu of fractional interests,
IDB stockholders will recognize no gain or loss in connection with the Merger;
and (iv) all material consents or approvals of governmental agencies or bodies
required in connection with the Merger. Certain of the terms and conditions of
the Merger, other than the requirement of shareholder approval, may be waived by
the parties. The Merger will become effective at the time of the filing, after
satisfaction or waiver of all of the conditions to the Merger, of a Certificate
of Merger with the Secretary of State of Delaware or at such later
 
                                       13
<PAGE>   24
 
time as may be specified in the Certificate of Merger (the "Effective Time").
The date on which the Effective Time occurs is referred to herein as the
"Closing Date." The Merger may be effected without regard to whether the WilTel
Acquisition is consummated. See "Plan of Merger -- Terms and Conditions of the
Proposed Merger -- Conditions of the Merger."
 
     The Merger Agreement may be amended at any time prior to the Effective Time
by the mutual written consent of the parties. The Merger Agreement may be
terminated at any time prior to the Effective Time by the mutual consent of the
parties or, unilaterally, by either party, if the Effective Time has not
occurred on or before March 31, 1995, and in certain other circumstances.
Termination by LDDS or IDB under certain circumstances will require the other
party to make an $8 million payment as liquidated damages. See "Plan of
Merger -- Terms and Conditions of the Proposed Merger -- Termination and
Amendment of the Merger Agreement."
 
ACCOUNTING TREATMENT
 
     LDDS intends to account for the Merger as a pooling of interests under
generally accepted accounting principles. Under the pooling of interests method
of accounting, the historical basis of the assets and liabilities of IDB and
LDDS will be combined, on a consolidated basis. See "Plan of
Merger -- Accounting Treatment."
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     In the opinion of O'Melveny & Myers, counsel to IDB, based on the
representations and assumptions referred to in their opinion, the Merger will
qualify as a reorganization under Section 368(a) of the Internal Revenue Code of
1986, as amended (the "Code"). No gain or loss will be recognized for federal
income tax purposes by IDB stockholders on the exchange of their IDB Shares
solely for LDDS Shares in the Merger (except for cash paid in lieu of fractional
shares). For a more complete description of the federal income tax consequences
of the Merger, see "Plan of Merger -- Certain Federal Income Tax Consequences."
 
     HOLDERS OF IDB SHARES, IDB OPTIONS OR IDB NOTES SHOULD CONSULT WITH THEIR
OWN TAX ADVISORS REGARDING THE TAX CONSEQUENCES OF THE MERGER TO THEIR
PARTICULAR SITUATION, INCLUDING THE APPLICABILITY OF ANY FOREIGN LAWS AS WELL AS
OTHER FEDERAL, STATE AND LOCAL LAWS.
 
LDDS'S REASONS FOR THE MERGER
 
     With pro forma consolidated 1993 revenues in excess of $2.0 billion
(excluding the WilTel Acquisition), the consolidation of IDB with LDDS is
expected to enhance LDDS's current position as one of the largest U.S. based
long distance telecommunications companies in the industry, serving customers
domestically and internationally. As a stronger competitor, LDDS believes the
consolidated entity should be in a better position to pursue LDDS's four-point
growth strategy, which consists of internal growth, the selective acquisition of
smaller long distance companies with limited geographic service areas and market
shares, the consolidation of certain third tier long distance carriers with
larger market shares, and international expansion.
 
     The Board of Directors of LDDS also believes that the Merger provides the
opportunity for significant cost savings primarily as a result of economies of
scale derived from the achievement of network and operational efficiencies. In
addition, the Board of Directors of LDDS believes that the Merger will create
greater liquidity for the shareholders of the consolidated organization and
provide greater access to capital markets than is currently enjoyed by LDDS
individually. See "Plan of Merger -- Reasons for the Merger; Board
Recommendations."
 
LDDS RECOMMENDATION
 
     At the meeting of LDDS's Board of Directors held to consider the Merger,
the directors of LDDS present carefully considered and unanimously approved the
terms of the Merger Agreement and the transactions contemplated thereby as being
fair and in the best interest of LDDS and the holders of LDDS Common Stock and
LDDS Preferred Stock (as hereinafter defined). THE LDDS BOARD OF DIREC-
 
                                       14
<PAGE>   25
 
TORS UNANIMOUSLY RECOMMENDS THAT THE SHAREHOLDERS OF LDDS VOTE "FOR" THE
PROPOSAL TO APPROVE THE ISSUANCE OF LDDS COMMON STOCK PURSUANT TO THE MERGER
AGREEMENT. For a discussion of the factors considered by the directors of LDDS
in reaching their decision, see "Plan of Merger -- Reasons for the Merger; Board
Recommendations."
 
OPINION OF LDDS'S FINANCIAL ADVISOR
 
     On July 28, 1994, Breckenridge Securities Corp. ("Breckenridge"), financial
advisor to LDDS, rendered its oral opinion (which it subsequently confirmed in
writing) to the Board of Directors of LDDS to the effect that, based upon the
facts and circumstances as they existed at that time and subject to the various
assumptions and other considerations set forth in such opinion, as of July 28,
1994, the Exchange Ratio was fair from a financial point of view to the holders
of LDDS Common Stock and LDDS Preferred Stock. A copy of Breckenridge's opinion
is attached as Appendix B to this Joint Proxy Statement/Prospectus and holders
of LDDS Common Stock and LDDS Preferred Stock are urged to read the opinion in
its entirety. See "Plan of Merger -- Opinions of Financial Advisors."
 
THE LDDS SPECIAL MEETING
 
     The LDDS Special Meeting will be held on December 29, 1994 at        .m.,
local time, at 515 East Amite St., Jackson, Mississippi. At such meeting, LDDS
shareholders will be asked to approve the issuance of LDDS Common Stock pursuant
to the Merger Agreement and the proposal to approve the 1995 Plan. See also
"Item 2. Approval of the LDDS Communications, Inc. 1995 Special Performance
Bonus Plan" for a discussion of the proposal to approve the 1995 Plan. The Board
of Directors of LDDS knows of no business that will be presented for
consideration at the LDDS Special Meeting other than the matters described in
this Joint Proxy Statement/Prospectus.
 
     Only the holders of record of LDDS Common Stock and LDDS Preferred Stock as
of the close of business on November 23, 1994 (the "LDDS Record Date") are
entitled to notice of and to vote at the LDDS Special Meeting. At the close of
business on the LDDS Record Date, there were           shares of LDDS Common
Stock outstanding, 10,896,785 shares of Series 1 $2.25 Cumulative Senior
Perpetual Convertible Preferred Stock (the "Series 1 Preferred Stock") and
2,000,000 shares of Series 2 6.5% Cumulative Senior Perpetual Convertible
Preferred Stock (the "Series 2 Preferred Stock") outstanding and entitled to
vote at the LDDS Special Meeting. On the LDDS Record Date, the shares of Series
1 Preferred Stock and Series 2 Preferred Stock (collectively, the "LDDS
Preferred Stock") were convertible into 21,876,976 shares and 4,233,087 shares,
respectively, of LDDS Common Stock.
 
     Holders of record of LDDS Common Stock as of the close of business on the
LDDS Record Date are entitled to one vote per share on any matter voted on at
the LDDS Special Meeting, whether voting as a class or voting together with LDDS
Preferred Stock. The holders of Series 1 Preferred Stock and Series 2 Preferred
Stock are entitled to vote, on an as-if-converted basis, together with holders
of LDDS Common Stock as a single class on the issuance of the LDDS Common Stock
pursuant to the Merger Agreement. The affirmative vote of the holders of at
least a majority of the total votes cast by the holders of the LDDS Common
Stock, the Series 1 Preferred Stock and the Series 2 Preferred Stock voting
together as a class at the LDDS Special Meeting is required to approve the
issuance of LDDS Common Stock pursuant to the Merger Agreement. Such approval is
required by the rules of the NASD in the case of the issuance of LDDS Common
Stock pursuant to the Merger. Approval of the 1995 Plan requires that more votes
be cast at the LDDS Special Meeting in favor of the 1995 Plan than are cast
against the 1995 Plan.
 
     The presence, either in person or by proxy, of the holders of a majority of
the votes entitled to be cast on the matter as of the LDDS Record Date is
necessary to constitute a quorum at the LDDS Special Meeting. Shares as to which
voting authority is withheld will be considered present for purposes of
determining the presence of a quorum at the LDDS Special Meeting but as not
entitled to vote, and not voted, for purposes of the approval of the issuance of
the LDDS Common Stock pursuant to the Merger Agreement. Shares as to which a
broker indicates it has no discretion to vote and which are not voted will be

of the approval of the issuance of the LDDS Common Stock pursuant to the Merger
Agreement. Shares voted to "abstain" will be considered to be present for
purposes of establishing a quorum but will not have any effect on the proposal
to approve the 1995 Plan. Shares as to which a broker indicates it lacks
authority to vote on such proposal and which are not voted will be considered
not present for purposes of determining the existence of a quorum and the
requisite majority vote.
 
     As of the LDDS Record Date, directors and executive officers of LDDS and
their affiliates (as a group) were entitled to vote           shares of LDDS
Common Stock and 10,896,785 shares of Series 1 Preferred Stock (representing
21,876,976 underlying shares of LDDS Common Stock), or approximately      % of
the outstanding votes entitled to be cast at the LDDS Special Meeting. All such
directors and executive officers and their affiliates have indicated their
intention to vote their shares for the approval of the issuance of LDDS Common
Stock pursuant to the Merger Agreement and for the approval of the 1995 Plan.
 
IDB'S REASONS FOR THE MERGER
 
     The Board of Directors of IDB believes that the Merger, whether or not the
WilTel Acquisition is consummated, offers IDB and its stockholders an attractive
opportunity to continue as stockholders of a company with enhanced financial and
operational strength. The Merger would create one of the largest U.S.-based long
distance telecommunications companies in the industry that could be expected to
compete more effectively in national and world markets than IDB alone. The Board
of Directors also believes that the Merger offers significant operating
efficiencies and cost savings. In addition, the WilTel Acquisition, if it is
consummated, is expected to amplify the benefits to IDB stockholders of the
Merger by further enhancing the consolidated organization's financial and
operational strength and providing additional opportunities for efficiencies and
cost savings. Although the WilTel Acquisition will result in a substantial
increase in the outstanding debt of LDDS, the IDB Board of Directors believes
that on balance the WilTel Acquisition would create a consolidated organization
which would be both stronger as an independent company and more attractive as an
acquisition candidate. See "Plan of Merger -- Reasons for the Merger; Board
Recommendations."
 
IDB RECOMMENDATION
 
     At the meetings of IDB's Board of Directors held to consider the Merger,
the directors of IDB carefully considered and unanimously approved the terms of
the Merger and the transactions contemplated thereby as being fair and in the
best interests of IDB and its stockholders, whether or not the WilTel
Acquisition is consummated. THE IDB BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS
THAT THE STOCKHOLDERS OF IDB VOTE FOR THE PROPOSAL TO APPROVE THE MERGER
AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY. For a discussion of the
factors considered by the directors of IDB in reaching their decision, see "Plan
of Merger -- Reasons for the Merger; Board Recommendations."
 
OPINIONS OF IDB'S FINANCIAL ADVISORS
 
     On July 28, 1994, Hambrecht & Quist Incorporated ("Hambrecht & Quist") and
Chemical Securities Inc. ("Chemical"), financial advisors to IDB, each rendered
its oral opinion (which each subsequently confirmed in writing) to the Board of
Directors of IDB to the effect that on and as of the date of such opinion, based
upon the procedures and subject to the assumptions described in such opinions,
in the case of Hambrecht & Quist, that the consideration to be received by the
holders of IDB Common Stock in the Merger is fair, from a financial point of
view, to such holders and, in the case of Chemical, that the Exchange Ratio is
fair, from a financial point of view, to the holders of IDB Common Stock. On
September 19, 1994, each of Hambrecht & Quist and Chemical reconfirmed their
opinions based upon facts known to them on that date, including the possibility
of the WilTel Acquisition. A copy of Hambrecht & Quist's and Chemical's
September 19, 1994 opinions are attached as Appendices C and D, respectively, to
this Joint Proxy Statement/Prospectus, and holders of IDB Common Stock are urged
to read the opinions in their entirety. See "Plan of Merger -- Opinions of
Financial Advisors."
 
                                       16

THE IDB SPECIAL MEETING
 
     The IDB Special Meeting will be held on December 29, 1994, at   :    .m.,
local time, at 515 East Amite St., Jackson, Mississippi. At such meeting, IDB
stockholders will be asked to approve the Merger Agreement and the transactions
contemplated thereby. If approved by the IDB and the LDDS stockholders, the
Merger may be consummated without regard to whether the WilTel Acquisition is
consummated. No substantive business will be presented for consideration at the
IDB Special Meeting other than the matters described in this Joint Proxy
Statement/Prospectus.
 
     Only the holders of record of IDB Common Stock as of the close of business
on November 23, 1994 (the "IDB Record Date") are entitled to notice of and to
vote at the IDB Special Meeting. At the close of business on the IDB Record
Date, there were           shares of IDB Common Stock outstanding and entitled
to vote at the IDB Special Meeting. Each share of IDB Common Stock will entitle
the holder to one vote at the IDB Special Meeting. The affirmative vote of at
least a majority of the outstanding shares of IDB Common Stock is required to
approve the Merger Agreement and the transactions contemplated thereby.
 
     The presence, either in person or by proxy, of the holders of a majority of
the outstanding shares of IDB Common Stock as of the IDB Record Date is
necessary to constitute a quorum at the IDB Special Meeting. The shares
represented by proxies marked "abstain" will be counted toward the requirements
for a quorum. Abstentions, however, will not constitute a vote "for" or
"against" approval of the Merger Agreement and the transactions contemplated
thereby and thus have the practical effect of voting against the Merger
Agreement. Shares of IDB Common Stock referred to as "broker non-votes" will be
treated as shares that are present and entitled to vote for purposes of
determining the presence of a quorum.
 
     As of the IDB Record Date, directors and executive officers of IDB and
their affiliates (as a group) were entitled to vote 5,184,463 shares of IDB
Common Stock, or approximately      % of the outstanding shares entitled to vote
at the IDB Special Meeting. All directors of IDB, who collectively are entitled
to vote 5,180,423 shares of IDB Common Stock, have indicated their intention to
vote their shares for the approval of the Merger Agreement and the transactions
contemplated thereby at the IDB Special Meeting.
 
MANAGEMENT AND OPERATIONS AFTER THE MERGER
 
     After the Merger, IDB is expected to continue to operate under its current
name as a subsidiary of LDDS. Following the Merger, it is anticipated that the
LDDS Board will consist of the current directors of LDDS and the IDB nominee
LDDS has agreed to elect or appoint to the LDDS Board pursuant to the terms of
the Merger Agreement. It is anticipated that Jeffrey P. Sudikoff, Chairman and
Chief Executive Officer of IDB, will be the IDB nominee appointed to serve as a
director on the LDDS Board. See "Plan of Merger -- Management and Operations
after the Merger."
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     In considering the recommendations of IDB's Board of Directors with respect
to the Merger Agreement, IDB stockholders should be aware that certain members
of IDB's management and its Board of Directors have interests in the Merger that
are in addition to their interests as IDB stockholders. These interests include,
among other matters, the interests of certain executive officers and directors
of IDB in employment agreements that provide for substantial payments as a
result of a change in control, such as the Merger; the interests of certain
executive officers of IDB in their anticipated new employment arrangements with
LDDS; the interests of certain executive officers and directors of IDB in stock
options that will immediately vest and become exercisable as a result of a
change in control, such as the Merger; the obligation of LDDS, under certain
circumstances, to appoint Mr. Sudikoff as a director of LDDS; the obligations of
LDDS to indemnify, advance the costs of defense of and hold harmless directors,
executive officers, employees and agents of IDB, under certain circumstances,
from claims, actions, suits or proceedings, including those referred to under
"-- Recent Developments Regarding IDB" above; and certain obligations of LDDS
with respect to employee benefit matters. The IDB Board was aware of these
interests in effect on the date of approval and considered them, among other
matters, in approving the Merger Agreement and the transactions contemplated
thereby. See "Plan of Merger -- Interests of Certain Persons in the Merger."

REGULATORY FILINGS AND APPROVALS
 
     Consummation of the Merger is contingent upon the receipt of approvals from
the FCC and various state PUCs with respect to the transfer of control of IDB to
LDDS and certain related transactions. LDDS and IDB previously have made the
necessary filings with government agencies. The applicable waiting period under
the Hart-Scott-Rodino Act has expired. See "Plan of Merger -- Certain Regulatory
Filings and Approvals."
 
DISSENTERS' RIGHTS
 
     Pursuant to Section 262(b) of the Delaware General Corporation Law, IDB
stockholders are not entitled to dissenters' or appraisal rights in connection
with the Merger, because: (i) shares of IDB Common Stock were, at the IDB Record
Date, designated as a Nasdaq National Market security; (ii) IDB stockholders
will not be required to accept anything in exchange for their IDB Shares other
than LDDS Shares (i.e., shares of stock which is designated as a Nasdaq National
Market security) and cash in lieu of fractional shares of such stock; and (iii)
the Restated Certificate of Incorporation of IDB does not otherwise provide IDB
stockholders with dissenters' or appraisal rights applicable to the Merger. LDDS
shareholders are also not entitled to dissenters' or appraisal rights with
respect to the Merger. See "Dissenters' Rights."
 
COMPARISON OF SHAREHOLDER RIGHTS
 
     See "Comparative Rights of Shareholders" for a summary of certain
differences between the rights of the holders of IDB Common Stock and LDDS
Common Stock.
 
MARKET PRICES
 
     The shares of LDDS Common Stock and IDB Common Stock are both quoted on the
Nasdaq National Market. Before the Prior Mergers, Resurgens' common stock was
traded on the American Stock Exchange (the "AMEX") under the trading symbol RCG.
At the close of business on September 14, 1993, Resurgens' common stock ceased
trading on the AMEX and, on September 15, 1993, LDDS Common Stock started
trading on the Nasdaq National Market under the trading symbol LDDS. The name of
Resurgens, the legal survivor, was changed to LDDS Communications, Inc. at the
time of the Prior Mergers. Before the Prior Mergers, LDDS-TN common stock was
traded on the Nasdaq National Market under the trading symbol LDDSA. Upon
effectiveness of the Prior Mergers on September 15, 1993, each share of the
outstanding Class A Common Stock of LDDS-TN was converted into the right to
receive 0.9595 shares of LDDS Common Stock; the information below has been
adjusted to reflect this exchange ratio. The following table sets forth the high
and low sales prices per share of LDDS Common Stock (including the common stock
of Resurgens and LDDS-TN prior to September 15, 1993) and IDB Common Stock as
reported on the Nasdaq National Market or the AMEX, as applicable, in each case
based on published financial sources, for the periods indicated.
 
     None of LDDS, Resurgens, LDDS-TN or IDB has ever paid any cash dividends on
its common stock. LDDS's existing and proposed new credit facilities prohibit
the payment of cash dividends on the LDDS Common Stock without the prior consent
of the lenders. None of IDB's existing debt agreements restricts its ability to
pay dividends on the IDB Common Stock. The per share information presented below
and elsewhere

splits and stock dividends of LDDS and IDB.

(1) At the close of business on September 14, 1993, in connection with the Prior
    Mergers, Resurgens' common stock ceased trading on the AMEX. On September
    15, 1993, LDDS Common Stock, the stock of the corporation surviving the
    Prior Mergers, commenced trading on the Nasdaq National Market. Accordingly,
    the high and low sales prices per share shown for Resurgens and LDDS-TN
    beginning on September 15, 1993 are the same and are the high and low sales
    prices per share of LDDS Common Stock.
 
     LDDS and IDB entered into the Merger Agreement on August 1, 1994. The
following table sets forth the closing prices for a share of LDDS Common Stock
and a share of IDB Common Stock as reported by Nasdaq National Market on July
13, 1994, the last trading day preceding the first public announcement of
negotiations concerning LDDS's possible acquisition of IDB, on July 29, 1994,
the last trading day preceding the public announcement of the execution of the
Merger Agreement, on August 1, 1994, the day of the public announcement of the

(1) See "Pro Forma Combining Financial Statements."
 
(2) The IDB pro forma equivalent represents the combined pro forma earnings,
    dividends and book value per common share of IDB and LDDS multiplied by an
    assumed Exchange Ratio of 0.450867 shares of LDDS Common Stock for each
    share of IDB Common Stock so that the IDB pro forma equivalent amounts
    represent the respective values of one share of IDB Common Stock. No
    assurance can be given as to the actual Exchange Ratio that will be utilized
    in the Merger.
 
(3) The data in the table excludes the WilTel Acquisition. If the WilTel
    Acquisition were included, selected IDB pro forma equivalent per share
    amounts would reflect book value per common share of $3.71 as of September
    30, 1994, primary (losses) per share of ($0.02) and ($0.63) for the year
    ended December 31, 1993 and the nine months ended September 30, 1994,
    respectively, and fully diluted (losses) per share of ($0.02) and ($0.63)
    for the year ended December 31, 1993 and the nine months ended September 30,
    1994, respectively.

SUMMARY FINANCIAL DATA
 
     The table on the following page presents selected historical financial data
of LDDS and IDB and selected unaudited pro forma financial data after giving
effect to the Merger as a pooling of interests for accounting purposes, assuming
the Merger had occurred at the beginning of the earliest period presented, but
without giving effect to direct acquisition costs or any resulting restructuring
costs associated with the consummation of the Merger. All such costs are
estimated to total $50 million, and include approximately $10 million of direct
acquisition costs. The pro forma financial data do not give effect to any
potential cost savings and synergies that could result from the Merger. The LDDS
historical data for each of the years in the five-year period ended December 31,
1993 are based on the historical financial statements of LDDS as audited by
Arthur Andersen LLP, independent auditors. The IDB historical data for each of
the years in the five-year period ended December 31, 1993 are based on the
historical financial statements of IDB as audited by Deloitte & Touche, LLP,
independent auditors. The selected financial data for LDDS for the nine month
periods ended September 30, 1994 and 1993 have been obtained from unaudited
financial statements and, in the opinion of the management of LDDS, include all
adjustments (of a normal and recurring nature) which are necessary to present
fairly the data for such periods. The selected financial data for IDB for the
nine month periods ended September 30, 1994 and 1993 have been obtained from
unaudited financial statements and, in the opinion of the management of IDB,
include all adjustments (all of which are of a normal and recurring nature
except as disclosed in the Notes to the Consolidated Financial Statements for
the nine months ended September 30, 1994 included herein) which are necessary to
present fairly the data for such periods. The pro forma data is not necessarily
indicative of the results of operations of the financial condition that would
have been reported had the Merger been in effect during those periods, or as of
those dates, or that may be reported in the future. Pro forma combined per share
data of LDDS and IDB give effect to the exchange of each share of IDB Common
Stock for 0.450867 of a share of LDDS Common Stock.
 
     These data should be read in conjunction with and are qualified in their
entirety by the consolidated financial statements of each of LDDS and IDB, and
the related notes thereto, incorporated by reference herein, and the pro forma
combining financial statements and the accompanying notes set forth elsewhere in
this Joint Proxy Statement/Prospectus. See "Available Information,"
"Incorporation by Reference," "Pro Forma Combining Financial Statements" and
"Management's Discussion and Analysis of the Pro Forma Combining Financial
Statements."

Notes to Summary Financial Data:
 
(1) IDB reclassified payments to foreign telephone companies to complete calls
    made from the United States by IDB's customers. These payments, which
    previously were classified as direct reductions of transmission services
    revenue, are now classified as cost of sales. Operating income (loss), net
    income (loss) available to common shareholders and the balance sheet are not
    affected. The amount of revenues reported by IDB for the years ended prior
    to December 31, 1993 do not reflect this reclassification because the
    amounts subject to reclassification were not material.
 
(2) During 1993, LDDS and IDB acquired various other long distance companies
    offering services similar or complementary to those offered by LDDS and IDB,
    respectively. The pro forma combined data for the year ended December 31,
    1993 and the nine months ended September 30, 1994 reflect unaudited results
    of operations as if the Prior Mergers and the acquisition of Dial-Net, Inc.
    ("Dial-Net") by LDDS and TRT Communications, Inc. ("TRT") by IDB had
    occurred at the beginning of 1993. During August 1994, LDDS also entered
    into an agreement to acquire WilTel. The following amounts reflect unaudited
    pro forma results of operations as if the Prior Mergers and the acquisitions
    of Dial-Net, TRT and WilTel had occurred at the beginning of 1993.

                                  RISK FACTORS
 
     The following factors should be considered carefully by the holders of LDDS
Common Stock, LDDS Preferred Stock and the holders of IDB Common Stock in
connection with the proposals to approve certain matters relating to the Merger
Agreement which will be voted upon at the Special Meetings.
 
FACTORS CONCERNING IDB
 
     RESIGNATION OF INDEPENDENT AUDITORS.  On May 23, 1994, Deloitte resigned as
IDB's independent auditors. Deloitte has stated it resigned as a result of
events surrounding the release and reporting of IDB's financial results for the
first quarter of 1994. In submitting its resignation, Deloitte informed IDB
management and the Audit Committee of the IDB Board of Directors that there had
been a serious breakdown in IDB's process of identifying, analyzing and
recording IDB's business transactions which prohibited Deloitte from the
satisfactory completion of a quarterly review, and that Deloitte was no longer
willing to rely on IDB management's representations regarding IDB's interim
financial statements. IDB announced Deloitte's resignation on May 31, 1994. On
June 24, 1994, upon the recommendation of the independent members of IDB's Audit
Committee, IDB retained Arthur Andersen LLP as its new independent auditors. On
August 22, 1994, IDB filed Amendment No. 1 on Form 10-Q/A restating its 1994
first quarter results in order to eliminate previously recorded items, which
items were among those as to which Deloitte had expressed disagreement.
 
     STOCKHOLDER LITIGATION.  Between June 1, 1994 and June 6, 1994, 22 class
action complaints were filed in the U.S. District Court for the Central District
of California on behalf of persons who purchased IDB Common Stock and IDB Notes
against IDB and the current directors and certain officers of IDB and other
parties. In addition, a class action complaint (Hassani v. IDB Communications
Group, Inc.) has been filed in California state court against IDB, its current
directors, certain of its executive officers and Deloitte alleging state law
violations. The complaints allege violations of federal and state securities
laws for disseminating allegedly false and misleading statements concerning
IDB's earnings and accounting practices. Stockholder derivative actions have
also been filed in federal court in California and the Delaware Chancery Court
(Steele v. Sudikoff, et al.). The District Court has ordered the 22 class action
complaints and the California derivative action consolidated as one action
styled In re IDB Communications Group, Inc. Securities Litigation. A
consolidated and amended complaint was filed in the District Court on November
18, 1994.
 
     On November 18, 1994, IDB, LDDS and representatives of the plaintiffs in
the foregoing litigation entered into a Stipulation of Settlement (the
"Stipulation"). The Stipulation provides that all claims that were or could have
been asserted by the plaintiffs against IDB or any of the other defendants in
the consolidated action, or on behalf of or by IDB against IDB directors and
officers will, subject to the fulfillment of certain conditions precedent and
the approval of the court, be settled and released and the litigation dismissed
in its entirety with prejudice in exchange for payments totalling $75.0 million.
The conditions precedent to the settlement include completion of the Merger,
timely payment of settlement funds to the escrow agents for the class action and
derivative action plaintiffs, and dismissal of the Delaware Chancery Court
derivative action and California state court class action. The Stipulation
terminates automatically in the event that Court approval is not obtained or any
of the other conditions precedent listed in the Stipulation do not occur, unless
counsel for the class action and derivative action plaintiffs and counsel for
IDB and LDDS mutually agree in writing to proceed with the Stipulation.
Consequently, there can be no assurance that the litigation will be settled and
dismissed on the terms described herein or at all.
 
     IDB is a party to indemnification agreements with certain of the other
defendants in the actions described above, including IDB's officers and
directors, certain selling shareholders and certain underwriters. IDB's officers
and directors are not covered by any applicable liability insurance. LDDS has
agreed to provide indemnification to IDB's officers and directors under certain
circumstances. See "Plan of Merger -- Interests of Certain Persons in the
Merger -- Indemnification" and "Comparative Rights of Shareholders -- 
Indemnification of Directors and Officers."

     INVESTIGATIONS AND OTHER PROCEEDINGS.  On June 9, 1994, the Commission
issued a formal order of investigation concerning certain matters, including
IDB's financial position, books and records and internal controls and trading in
IDB securities on the basis of non-public information. The Commission has issued
subpoenas to IDB and others, including Mr. Sudikoff, in connection with its
investigation. The NASD and other self-regulatory bodies have also made
inquiries of IDB concerning similar matters. IDB is cooperating with the
Commission's investigation and the other inquiries and is in the process of
complying with the subpoenas it has received.
 
     In October 1994, the U.S. Attorney's Office for the Central District of
California issued grand jury subpoenas to IDB seeking documents relating to
IDB's first quarter results and the Deloitte resignation. IDB has been informed
that a criminal investigation has commenced and is cooperating with the U.S.
Attorney's Office.
 
     OTHER LITIGATION.  On August 20, 1994, SynTech filed a complaint in the
U.S. District Court for the District of Columbia alleging that IDB Mobile is
infringing upon SynTech's copyrights in certain computer software. On September
7, 1994, IDB Mobile filed counterclaims against SynTech for, among other things,
breach of contract and interference with IDB Mobile's contracts with its
customers. Both parties filed motions for summary judgment, which were heard on
November 16, 1994. The parties are awaiting the court's ruling regarding their
respective motions for summary judgment.
 
     On October 12, 1994, Community Network Services, Inc., a reseller of local
and long distance telephone service in New York, filed a complaint in the U.S.
District Court for the Southern District of New York alleging breach of
contract, false advertising under the Lanham Act and a violation of the
Racketeering and Corrupt Organization Act (RICO) based on IDB's termination of
service to the plaintiff.
 
     On October 21, 1993, Euronet, Incom, Benjamin Lebovitz and Eli Lior filed a
complaint in the U.S. District Court for the Southern District of New York
against IDB and certain IDB personnel, alleging that IDB breached an oral
agreement to enter into a joint venture with Euronet and that the employee
defendants committed fraud by failing to disclose that IDB had entered into a
similar joint venture with a competitor of Euronet. The plaintiffs also allege
that IDB breached separate agency and sales representative agreements and seek
compensatory and punitive damages and injunctive relief.
                            ------------------------
 
     IDB is unable at this time to predict the outcome of any of the foregoing
litigation, investigations or other proceedings. However, if determined
adversely to IDB, the impact of such matters on the financial position and
results of operations of IDB or, if the Merger is consummated, the consolidated
organization, could be material. See "Plan of Merger -- Terms and Conditions of
the Proposed Merger -- Accounting Contingency," "-- Interests of Certain Persons
in the Merger -- Indemnification," "Information Regarding IDB -- Recent
Developments," "Pro Forma Combining Financial Statements" and "Management's
Discussion and Analysis of the Pro Forma Combining Financial Statements."
 
     RESTATED AND RECENT FINANCIAL RESULTS.  On August 1, 1994, IDB announced
that it would restate its reported financial results for the quarter ended March
31, 1994 to eliminate approximately $6 million of pre-tax income, approximately
$5 million of which related to a sale of transponder capacity and approximately
$1 million of which related to purchase accounting adjustments. On November 21,
1994, IDB filed Form 10-Q/A amendments to its reported first and second quarter
financial results making the previously announced changes and reflecting the
effect of IDB's method of accounting for international long distance traffic,
thereby reducing its first quarter net income from $0.12 per share, as
originally reported, to $0.05 per share and, when combined with adjustments for
income tax effects, increasing its second quarter net loss from $0.20 per share,
as originally reported, to $0.27 per share.
 
     For its third quarter ended September 30, 1994, IDB reported a net loss,
after income taxes, of $154.7 million or $2.08 per share on revenues of $131
million. For the nine months ended September 30, 1994, IDB reported a net loss,
after income taxes, of $170.5 million or $2.31 per share on revenues of $378.1
million. Operating results in the third quarter of 1994 were significantly
affected by a stockholder litigation provision of $76.0 million, a reduction in
carrying value of certain IDB Broadcast assets of $35.0 million and a valuation
reserve of $18.3 million provided against deferred tax assets. The pre-tax loss
in the third quarter also reflects
 
                                       25
<PAGE>   36
 
significant one time expenses of approximately $2.0 million related to the
Merger, and approximately $2.5 million in accounting and legal expenses incurred
in connection with the resignation of Deloitte and the ensuing litigation. IDB
also accrued approximately $2.4 million for various non-income tax and related
matters in the third quarter. See "Available Information," "Incorporation by
Reference," "Pro Forma Combining Financial Statements" and "Management's
Discussion and Analysis of the Pro Forma Combining Financial Statements."
 
     As a result of these losses incurred by IDB in the third quarter, IDB is in
default with respect to certain covenants not relating to payment under its line
of credit with Bank of America. IDB is currently negotiating with Bank of
America to obtain a waiver of such default. There can be no assurance that any
such waiver will be obtained.
 
     RISKS OF INTERNATIONAL BUSINESS.  IDB derives substantial revenues by
providing international communication services primarily to customers
headquartered in the United States. Such operations are subject to certain risks
such as changes in foreign government regulations and telecommunication
standards, licensing requirements, tariffs or taxes and other trade barriers and
political and economic instability. In addition, IDB's revenues and cost of
sales are sensitive to changes in international settlement rates. International
rates may decrease in the future due to aggressiveness on the part of existing
carriers, aggressiveness on the part of new entrants into niche markets, the
widespread resale of international private lines, the consummation of joint
ventures among large international carriers that facilitate targeted pricing and
cost reductions, and the rapid growth of international circuit capacity due to
the deployment of new transatlantic and transpacific fiber optic cables. If the
Merger is consummated, the international operations of the consolidated
organization will also be subject to these same risks. The anticipated increased
traffic volumes and cost reductions related to the Merger may not offset any
resulting rate decreases.
 
FACTORS CONCERNING LDDS
 
     RISKS OF INCREASED FINANCIAL LEVERAGE; DEBT SERVICE, INTEREST RATE
FLUCTUATIONS, POSSIBLE REDUCTION IN LIQUIDITY, DIVIDEND RESTRICTIONS, AND OTHER
RESTRICTIVE COVENANTS.  If the WilTel Acquisition is consummated, LDDS will, as
a result of the financing thereof, have a significantly higher degree of
leverage than currently exists. At September 30, 1994, LDDS reported $519.2
million of long-term debt (including capital leases) and a debt to equity ratio
of 0.30; IDB reported $205.5 million of long-term debt and a debt to equity
ratio of 1.43. Based on LDDS's pro forma balance sheet at September 30, 1994, as
a result of the acquisition of IDB, LDDS would have long-term debt (including
capital leases) of $724.7 million and a debt to equity ratio of 0.38; and as a
result of the acquisition of IDB and WilTel and the financing of the WilTel
Acquisition, LDDS would have long-term debt (including capital leases) of $3.4
billion and a debt to equity ratio of 1.8.
 
     Borrowings under LDDS's existing and proposed bank credit facilities bear
interest at rates that fluctuate with prevailing short-term interest rates.
Increases in interest rates on these obligations would have an adverse effect
upon LDDS's reported net income and cash flow. In addition, these credit
facilities restrict the payment of dividends and otherwise limit LDDS's
financial flexibility. See "Information Regarding LDDS -- Recent Developments"
for a description of LDDS's proposed credit facilities. Management of LDDS
believes that the combined operations of LDDS, IDB and WilTel would generate
sufficient cash flow to service LDDS's debt under the proposed bank credit
facilities upon consummation of the proposed WilTel Acquisition; however,
economic downturns, increased interest rates and other adverse developments,
including factors beyond LDDS's control, could impair its ability to service the
resulting indebtedness. In addition, the cash flow required to service LDDS's
debt would reduce its liquidity, which in turn may reduce its ability to fund
internal growth, additional acquisitions and capital improvements. Facility B of
the proposed bank credit facilities, which totals $1.25 billion, would mature in
a single installment on December 31, 1996. Facility A, which totals $2.16
billion, would mature in a series of varying quarterly installments from 1996
through 2000.
 
     LDDS anticipates it would need to refinance Facility B, which would require
LDDS to seek other financing alternatives such as public or private debt or
equity offerings, or refinancing with the existing or new lenders, although, to
the extent available, Facility A may be used to refinance Facility B. No
assurance can be given that any such refinancing would be available on terms
reasonably acceptable to LDDS. See "Pro Forma
 
                                       26
<PAGE>   37
 
Combining Financial Statements" and "Management's Discussion and Analysis of the
Pro Forma Combining Financial Statements."
 
     INTEGRATION OF WILTEL.  Although LDDS believes that significant networking
and operational efficiencies and growth opportunities will be created by
combining the operations of WilTel and LDDS, if the WilTel Acquisition is
consummated, there can be no assurance that WilTel's operations will be
completely integrated with LDDS's operations or that the efficiencies and growth
opportunities anticipated to result from the combination of LDDS and WilTel will
materialize. See "-- Factors Concerning LDDS and IDB -- Acquisition Integration"
and "Information Regarding LDDS -- Recent Developments."
 
     MANAGEMENT CONTROL OF LDDS.  As of the LDDS Record Date, the current
directors and executive officers of LDDS and their affiliates beneficially owned
approximately 39% of the outstanding shares of LDDS Common Stock, including
shares which may be acquired upon exercise of options and warrants and
conversion of LDDS Preferred Stock (and will own from approximately 30% to 31%
after the Merger). MCC alone is the beneficial owner of approximately 20% of
such shares (and will own from approximately 15% to 16% after the Merger),
including approximately 21.9 million shares of LDDS Common Stock issuable upon
conversion of LDDS's Series 1 Preferred Stock. In addition, after the Merger,
Mr. Sudikoff, who is expected to be appointed a director of LDDS, will
beneficially own from      % to      % of the outstanding shares of LDDS Common
Stock, based on his beneficial ownership of IDB Common Stock as of the IDB
Record Date. See "Plan of Merger -- Interests of Certain Persons in the
Merger -- Director Nominee." This level of stock ownership by management could
result in its ability to substantially influence the outcome of voting on
proposals submitted to a vote of shareholders, such as the election of
directors, amendments to the Amended and Restated Articles of Incorporation of
LDDS, and potential acquisitions of LDDS by other companies.
 
     ANTI-TAKEOVER PROVISIONS.  The Amended and Restated Articles of
Incorporation of LDDS contain provisions (a) requiring a 70% vote for approval
of certain business combinations with certain 10% shareholders unless approved
by a majority of the continuing Board of Directors or unless certain minimum
price, procedural and other requirements are met; (b) restricting aggregate
beneficial ownership of the capital stock of LDDS by foreign shareholders to 20%
of the total outstanding capital stock, and subjecting excess shares to
redemption; and (c) requiring a two-thirds vote of the holders of the Series 2
Preferred Stock to approve certain extraordinary transactions or, alternatively,
redemption of such stock at a specified premium. In addition, the Bylaws of LDDS
(a) contain requirements regarding advance notice of nomination of directors by
shareholders, and (b) restrict the calling of special meetings by shareholders
to those owning shares representing not less than 40% of the votes to be cast.
These provisions may have an "anti-takeover" effect. See "Comparative Rights of
Shareholders" herein and "Information Regarding Resurgens -- Amendments to
Resurgens' Restated Articles of Incorporation -- LDDS Merger Agreement,"
"Proposals No. 1 and 2 -- The Proposed Mergers -- Description of the Series 2
Preferred Stock" and "-- Special Redemption Provisions" contained in the 1993
Joint Proxy Statement/Prospectus, which hereby are incorporated herein by
reference.
 
     CONTINGENT LIABILITIES.  LDDS and WilTel are each subject to a number of
legal and regulatory proceedings. While management believes that the probable
outcome of any of these matters, or all of them combined, will not have a
material adverse effect on LDDS's consolidated results of operations or
financial position, no assurance can be given that a contrary result will not
obtain. See Item 3 -- "Legal Proceedings" contained in the 1993 LDDS Form 10-K,
Item 1 of Part II of each of the 1994 LDDS Form 10-Q's, and Note 11 to the
Combined Financial Statements of WilTel Network Services for the nine month
period ended September 30, 1994, contained in LDDS's Current Report on Form 8-K
dated August 22, 1994 (filed September 8, 1994) (as amended by Current Report on
Form 8-K/A filed November 17, 1994), which hereby are incorporated herein by
reference.
 
FACTORS CONCERNING LDDS AND IDB
 
     ACQUISITION INTEGRATION.  A major portion of LDDS's and IDB's respective
growth in recent years has resulted from acquisitions, which involve certain
operational and financial risks. Operational risks include the possibility that
an acquisition does not ultimately provide the benefits originally perceived by
management of
 
                                       27
<PAGE>   38
 
the acquiror, while the acquiror continues to incur operating expenses to
provide the services formerly provided by the acquired company. Financial risks
involve the incurrence of indebtedness by the acquiror in order to effect the
acquisition and the consequent need to service that indebtedness. In addition,
the issuance of stock in connection with acquisitions dilutes the voting power
and may dilute certain other interests of existing shareholders. In carrying out
its acquisition strategy, LDDS and IDB each attempts to minimize the risk of
unexpected liabilities and contingencies associated with acquired businesses
through planning, investigation and negotiation, but such unexpected liabilities
may nevertheless accompany acquisitions. There can be no assurance that LDDS,
IDB or the consolidated organization will be successful in identifying
attractive acquisition candidates or completing additional acquisitions on
favorable terms.
 
     In addition, although management of LDDS believes that it will be able to
integrate successfully the business and operations of IDB and WilTel, there can
be no assurance that LDDS will be able to accomplish such integration or
integrate any other acquired businesses into its operations and obtain the
desired networking and operating efficiencies. There can also be no assurance
that the anticipated growth opportunities resulting from the consolidated
organization will materialize. See "Plan of Merger -- Background of the Merger,"
"-- Reasons for the Merger; Board Recommendations" and "Management's Discussion
and Analysis of the Pro Forma Combining Financial Statements."
 
     INTERESTS OF CERTAIN PERSONS IN THE MERGER.  In considering the
recommendations of IDB's Board of Directors with respect to the Merger
Agreement, IDB stockholders should be aware that certain members of IDB's
management and its Board of Directors have interests in the Merger that are in
addition to their interests as IDB stockholders. These interests include, among
other matters, the interests of certain executive officers and directors of IDB
in employment agreements that provide for substantial payments as a result of a
change in control, such as the Merger; the interests of certain executive
officers of IDB in their anticipated new employment arrangements with LDDS; the
interests of certain executive officers and directors of IDB in stock options
that will immediately vest and become exercisable as a result of a change in
control, such as the Merger; the obligation of LDDS, under certain
circumstances, to appoint Mr. Sudikoff, Chairman and Chief Executive Officer of
IDB, as a director of LDDS; the obligations of LDDS to indemnify, advance the
costs of defense of and hold harmless directors, executive officers, employees
and agents of IDB, under certain circumstances, from claims, actions, suits or
proceedings, including those referred to under "Factors Concerning
IDB -- Stockholder Litigation" and "-- Investigations and Other Proceedings"
above; and certain obligations of LDDS with respect to employee benefit matters.
The IDB Board was aware of these interests in effect on the date of approval and
considered them, among other matters, in approving the Merger Agreement and the
transactions contemplated thereby. See "Plan of Merger -- Interests of Certain
Persons in the Merger."
 
     FAIRNESS OPINIONS -- INTERESTS OF FINANCIAL ADVISORS. In approving the
Merger Agreement and the transactions contemplated thereby, the Boards of
Directors of LDDS and IDB considered the fairness opinions of their respective
financial advisors. See "Plan of Merger -- Opinions of Financial Advisors."
Breckenridge, LDDS's financial advisor, and Hambrecht & Quist and Chemical,
IDB's financial advisors, are each entitled to a fee that is contingent upon the
consummation of the Merger. Hambrecht & Quist also is a defendant in certain
litigation involving IDB (see "Information Regarding IDB -- Recent
Developments -- Stockholder Litigation") and is a market maker for IDB
securities. Chemical and certain of its affiliates have provided, and may
provide in the future, commercial and investment banking services to Williams.
An affiliate of Chemical has provided personal banking services to certain
officers and directors of IDB and LDDS, and has agreed to participate as a
member of the syndicate of banks which may provide financing to LDDS in
connection with the WilTel Acquisition. In addition, none of the financial
advisors independently appraised the possible effects of pending or potential
litigation involving LDDS, WilTel or IDB.
 
     DEPENDENCE ON AVAILABILITY OF TRANSMISSION FACILITIES.  The future
profitability of LDDS, IDB and the consolidated organization will be dependent
in part on their respective ability to utilize transmission facilities leased
from others on a cost-effective basis, particularly if the WilTel Acquisition is
not consummated. Due to the possibility of unforeseen changes in industry
conditions, the continued availability of leased transmission facilities at
historical rates cannot be assured. See Item 1 -- "Business -- Transmission
Facilities" contained
 
                                       28
<PAGE>   39
 
in the 1993 LDDS Form 10-K and Item 1 -- "Business -- Facilities" contained in
the 1993 IDB Form 10-K, which are hereby incorporated herein by reference.
 
     REGULATION RISKS.  LDDS and IDB are each subject, and the consolidated
organization will be subject, to extensive regulation at the federal and state
levels, as well as in various foreign countries in connection with certain
overseas business activities. The regulatory environment varies substantially by
jurisdiction.
 
     The regulation of the telecommunications industry is changing rapidly, and
there can be no assurance that future regulatory changes will not have a
material adverse impact on LDDS, IDB or the consolidated organization. Recent
developments include, without limitation, consideration by Congress of
legislation that would modify the 1982 AT&T divestiture decree's (the "AT&T
Divestiture Decree") restrictions on the provision of long distance services
between local access and transport areas ("LATAs"), as defined in the AT&T
Divestiture Decree, by the Bell Operating Companies ("BOCs"); consideration by
the Justice Department and courts of related BOC requests for waiver of the AT&T
Divestiture Decree to permit them to provide significant interLATA services
(such as service outside their respective regions, to mobile customers, and in
other circumstances) or for the elimination of the AT&T Divestiture Decree
altogether; FCC and PUC action changing access rates charged by local exchange
carriers ("LECs") and making other related changes to access and interconnection
policies, certain of which could have adverse consequences for the consolidated
organization; related FCC and state regulatory proceedings considering
additional deregulation of LEC access pricing; a pending FCC rulemaking on
"billed party preference" that could affect LDDS's provision of operator
services; and various legislative and regulatory proceedings that would result
in new local exchange competition.
 
     Transmissions from earth stations to all satellites, transmissions from
microwave and other transmitters, reception from international satellites, and
transmission of international traffic by any means, including satellite and
undersea cable, must be pursuant to license or other authorizations issued by
the FCC. IDB has operating authority or has made other suitable arrangements to
transmit and/or receive signals from all locations where it currently offers
satellite transmission and/or reception service. Although IDB has never had a
license application denied by the FCC, there can be no assurance that IDB will
receive all authorizations or licenses necessary for new communications services
or that delays in the licensing process will not adversely affect IDB's
business. Some of IDB's services, and most of LDDS's services, are deemed common
carriage and as such must be provided at just and reasonable rates and free of
all unlawful discrimination. IDB and LDDS monitor compliance with federal, state
and local regulations governing the discharge and disposal of hazardous and
environmentally sensitive materials, including the emission of electromagnetic
radiation. Although IDB and LDDS believe that they are in compliance with such
regulations, there can be no assurance that any such discharge, disposal or
emission might not expose IDB or LDDS, or the consolidated organization, to
claims or actions that could have a material adverse effect on financial
results. See Item 1 -- "Business -- Regulation" contained in the 1993 LDDS Form
10-K and Item 1 -- "Business -- Government Regulation" contained in the 1993 IDB
Form 10-K, which are hereby incorporated herein by reference.
 
     WilTel generally operates in the same regulatory environment as LDDS and
IDB. See "Information Regarding LDDS -- Recent Developments."
 
     COMPETITION RISKS.  LDDS and IDB each faces, and the consolidated
organization will face, intense competition in providing long distance
telecommunications services. IDB competes for international services with other
facilities-based interexchange carriers ("IXCs"), including AT&T, MCI and
Sprint, and LDDS competes for interLATA services with other national and
regional IXCs, including AT&T, MCI and Sprint; with respect to intraLATA long
distance services, with AT&T, MCI, Sprint, the LECs and other IXCs, where
permissible; and with respect to operator service, with AT&T and other operator
service providers. In the radio and television broadcast industry, IDB
encounters competition from several of the larger companies in both the cable
and telecommunications market as well as smaller, more entrepreneurial industry
participants. Certain of these companies have substantially greater market share
and financial resources than LDDS, IDB or the consolidated organization, and
some of them are the source of communications capacity used by LDDS and IDB to
provide their own respective services. LDDS expects to encounter increasing
competition from major domestic and international communications companies,
including AT&T, MCI and Sprint, as a result
 
                                       29
<PAGE>   40
 
of the Merger and the WilTel Acquisition. In addition, in the future, LDDS and
IDB, and the consolidated organization, may be subject to additional
competition due to the development of new technologies. See Item 1 -- "Business
- -- Competition" contained in the 1993 LDDS Form 10-K and Item 1 -- "Business --
Competition" contained in the 1993 IDB Form 10-K, which are hereby incorporated
herein by reference.
 
     WilTel is generally subject to the same competitive pressures as LDDS and
IDB. See "Information Regarding LDDS -- Recent Developments." In addition, even
though fiber-optic networks for long distance transmission are now widely used,
it is possible that the desirability of such networks could be adversely
affected by changing technology. The telecommunications industry is in a period
of rapid technological evolution, marked by the introduction of new product and
service offerings. Neither LDDS, IDB nor WilTel can predict which of many
possible future product and service offerings will be important to maintain
their respective competitive positions or what expenditures will be required to
develop and provide such products and services.
 
                                 PLAN OF MERGER
 
     The following is a summary of the material terms and conditions of the
Merger Agreement, a copy of which is appended as Appendix A to this Joint Proxy
Statement/Prospectus and incorporated herein by reference. The information
regarding the Merger Agreement in this summary and elsewhere in this Joint Proxy
Statement/Prospectus does not purport to be complete and is qualified in its
entirety by reference to the full text of the Merger Agreement.
 
GENERAL DESCRIPTION OF THE MERGER
 
     Pursuant to the Merger Agreement, at the Effective Time, LDDS will acquire
IDB through the merger of Acquisition Subsidiary with and into IDB. If the
issuance of LDDS Common Stock is approved by the shareholders of LDDS and the
Merger Agreement and the transactions contemplated thereby are approved by the
stockholders of IDB, and if the other conditions to the Merger are satisfied or
waived, the Merger will become effective upon the filing by the Surviving
Corporation with the Secretary of State of the State of Delaware of a duly
executed Certificate of Merger or at such later time as may be specified in the
Certificate of Merger. The Merger may be effected without regard to whether the
WilTel Acquisition is consummated.
 
     At the Effective Time, each holder of IDB Common Stock will be entitled to
receive the number of whole shares of LDDS Common Stock equivalent to the number
of shares of IDB Common Stock owned immediately prior to the Effective Time
multiplied by the Exchange Ratio. The Exchange Ratio will be based upon the
Share Value. See "Summary Information -- The Proposed Merger." If the Share
Value is equal to or less than $16.00, the Exchange Ratio will be 0.520231. If
the Share Value is equal to or greater than $22.00, the Exchange Ratio will be
0.450867. If the Share Value is greater than $16.00 but less than $22.00, the
Exchange Ratio increases or decreases by 0.001445 of an LDDS Share for each
$0.125 decrease or increase, respectively, in the Share Value, as more fully set
forth in Section 1.3 of the Merger Agreement (provided that if the Share Value
falls between any two of the Share Values listed therein, the Exchange Ratio
shall be that applicable to the lower of the two Share Values). Fractional
shares of LDDS Common Stock will not be issued; instead, IDB stockholders who
would otherwise be entitled to fractional shares of LDDS Common Stock will
receive cash in lieu thereof. See "-- Fractional Shares." The closing price for
the LDDS Common Stock on             , 1994 was $          . Based on an assumed
Exchange Ratio of      , an assumed Share Value of $          and an assumed
number of        shares of IDB Common Stock outstanding, the stockholders of IDB
would receive LDDS common stock having a market value of $          million in
the aggregate, or $          per share of IDB Common Stock, in the Merger. No
assurance can be given as to the actual Exchange Ratio that will be utilized in
the Merger or the actual Share Value.
 
     Based on the capitalization of LDDS and IDB as of             , 1994, the
stockholders of IDB immediately prior to the consummation of the Merger will own
securities representing from approximately 19.5% to approximately 21.8% of the
outstanding LDDS Common Stock on a fully diluted basis following consummation of
the Merger, based on the minimum and maximum Exchange Ratios, respectively.
 
                                       30
<PAGE>   41
 
     IDB Options will be converted into options to purchase shares of LDDS
Common Stock, with a proportional adjustment being made to the exercise price of
and the number of shares subject to each such option to reflect the Exchange
Ratio. In addition, pursuant to the underlying indenture, each outstanding IDB
Note will become convertible into shares of LDDS Common Stock, with a
proportional adjustment being made to the conversion price of such IDB Note to
reflect the Exchange Ratio. See "-- Effect of Merger on IDB Notes."
 
     Following the Effective Time, each stockholder of IDB will be required to
surrender the certificates which theretofore represented shares of IDB Common
Stock to First Union National Bank of North Carolina, or such other bank or
trust company as may be designated by LDDS (the "Exchange Agent"), together with
a duly completed and executed transmittal letter provided by the Exchange Agent.
See "-- Surrender of Stock Certificates and Receipt of Merger Consideration." No
fractional shares of LDDS Common Stock will be issued in the Merger, but cash
will be paid in lieu of such fractional shares. See "-- Fractional Shares." The
shares of LDDS Common Stock to be issued pursuant to the Merger will be freely
transferable except by certain stockholders of IDB who are deemed to be
"affiliates" of IDB. The shares of LDDS Common Stock issued to such affiliates
will be restricted in their transferability in accordance with rules and
regulations promulgated by the Commission. See "-- Status Under Federal
Securities Laws."
 
     As soon as practicable after the Effective Time, the Exchange Agent will
mail to each holder of IDB Common Stock notification of the consummation of the
Merger and instructions as to the procedure for the surrender of the stock
certificates. The Exchange Agent will accept documentation acceptable to it in
lieu of lost or destroyed certificates and may also require the holder of a lost
or destroyed certificate to post an insurance bond acceptable to the Exchange
Agent. Each holder of IDB Common Stock, upon surrender of a stock certificate or
certificates representing such stock, together with the transmittal letter
provided by the Exchange Agent duly completed and executed by such holder, will
be entitled to receive a stock certificate or certificates representing the
number of the whole shares of LDDS Common Stock (together with cash in lieu of
fractional shares) to which such holder is entitled.
 
     IDB STOCKHOLDERS SHOULD NOT SEND IN THEIR CERTIFICATES UNTIL THEY RECEIVE A
TRANSMITTAL LETTER FROM THE EXCHANGE AGENT.
 
BACKGROUND OF THE MERGER
 
     LDDS and IDB, each on a regular basis, analyze other companies within their
industry for the purpose of evaluating potential acquisition and merger
opportunities which may be available. Under appropriate circumstances, direct or
indirect contact with potential acquisition and merger candidates identified
through this process occurs.
 
     The first contact between management of LDDS and IDB relevant to the Merger
occurred in San Diego, California in July of 1993, after Alan A. McClure of
Breckenridge contacted Jeffrey P. Sudikoff, Chairman and Chief Executive Officer
of IDB, to be a panelist for a conference being held there. Attending this
meeting were Bernard J. Ebbers, President and Chief Executive Officer of LDDS,
Mr. Sudikoff, and Wilkie S. Colyer and Mr. McClure of Breckenridge. The purpose
of this initial meeting was for the parties to discuss and evaluate each other's
business. No substantive discussion occurred regarding a possible business
combination between the two companies.
 
     In anticipation of the possibility of exchanging confidential information,
LDDS and IDB executed a mutual confidentiality agreement as of July 9, 1993.
However, no confidential information was exchanged between the two parties and
no substantive conversations regarding a possible business combination occurred
until mid-May of 1994, when Mr. Ebbers contacted Mr. Sudikoff to arrange a
meeting in New York on June 1, 1994 to discuss such a combination. Mr. Ebbers
advised the LDDS Board of Directors of the proposed meeting with Mr. Sudikoff at
the meeting of the LDDS Board on May 26, 1994.
 
     The meeting on June 1, 1994 was among Mr. Sudikoff, Edward R. Cheramy,
President of IDB, Stephen N. Carroll, President of IDB WorldCom, Mr. Ebbers and
Mr. Colyer. The meeting covered several topics relating to a possible merger,
including the strategic fit of IDB's international business and operating
 
                                       31

agreements with LDDS's domestic network, the possible basis for an exchange
ratio, the potential cost savings from a combination and the nature of IDB's
dispute with its independent auditors. Although IDB proposed a possible exchange
ratio based on a fixed value of IDB Common Stock, the discussion of this
proposal was preliminary in nature because neither company had commenced due
diligence or had sufficient information pertaining to each other's companies and
businesses.
 
     Shortly after this meeting, LDDS and IDB commenced legal and business due
diligence reviews of each other by exchanging certain confidential information.
At the commencement of due diligence, LDDS retained Breckenridge to act as its
financial advisor and IDB engaged Hambrecht & Quist to act as its financial
advisor in connection with the negotiation of the proposed merger. Breckenridge
(either directly or through an affiliate) and Hambrecht & Quist had been engaged
by LDDS and IDB, respectively, in the past with respect to financial advisory
services and were thus knowledgeable of the business, operations and management
of the respective companies. In light of Hambrecht & Quist's prior relationships
with IDB in acting as an underwriter in a number of public offerings of IDB
securities and because Hambrecht & Quist had been named as a defendant in
litigation relating to those offerings, IDB also retained Chemical to act as a
financial advisor and to deliver a second fairness opinion in connection with
any proposed transaction. See "Information Regarding IDB -- Recent Developments
- -- Stockholder Litigation."
 
     Throughout June and July of 1994, officers and management of LDDS and IDB
and representatives of Breckenridge and Hambrecht & Quist met on several
occasions to conduct due diligence to better understand each other's companies
and businesses, to discuss possible exchange ratios and to determine if the
proposed Merger could be consummated. In connection with the exchange ratio
negotiations, LDDS and IDB provided certain financial information, including
projections, to representatives of their respective financial advisors and the
other company. The projections consisted of income statement projections and
certain supporting assumptions for fiscal years 1994 and 1995 presented on a
quarterly basis and, in the case of IDB, by business unit. The assumptions
utilized in the IDB projections included information regarding the number of
inbound and outbound minutes and the associated rates. IDB's original
projections were subsequently updated in July principally to reflect the impact
of the change to IDB's method of accounting for international long distance
traffic.
 
     At the initial due diligence meeting held on June 13 and 14,
representatives of LDDS and Breckenridge explained that an exchange ratio based
on a fixed value of IDB Common Stock would not be acceptable. Instead, the
parties agreed preliminarily to consider an exchange ratio emphasizing the
relative contributions of stand-alone 1995 revenue and earnings projections of
LDDS and IDB to the combined company, and possible cost savings and synergies
from the business combination. Such factors were considered relevant because the
parties believed the proposed merger, if pursued, would be consummated by the
end of 1994, which meant that 1995 would represent the first full year of
combined operations. The focus on revenues and earnings reflected the parties'
view that such criteria are important measures of financial performance. In
addition, the parties focused on 1995 projections because projected returns in
any subsequent year were considered inherently more speculative. Another factor
affecting the exchange ratio discussions was the belief of representatives of
both companies that, to be acceptable to LDDS's shareholders, any proposed
transaction should be accretive to projected 1995 LDDS earnings per share. Any
proposed transaction with a projected dilutive effect on 1995 LDDS earnings per
share was viewed as having a possible negative impact on the market price of
LDDS Common Stock.
 
     At a subsequent meeting held in Denver on June 16, Messrs. Cheramy, Colyer,
Ebbers and Sudikoff and David Golden of Hambrecht & Quist met to discuss
possible exchange ratios. LDDS proposed an exchange ratio range, with maximum
and minimum ratios, due to concerns relating to stock price volatility and IDB's
revenue recognition policies, pending litigation regarding IDB, growth
expectations of both companies, reserve adjustments of IDB, and other due
diligence matters.
 
     During the next several weeks, representatives of LDDS and IDB continued
due diligence investigations of each other's companies and businesses, with
particular focus on, among other things, possible savings from the business
combination, pending litigation and investigations relating to IDB, and IDB's
method of revenue recognition. These investigations included meetings held on
June 21 and 22 in Los Angeles, with a particular focus on due diligence
regarding the operations of IDB, and on June 23 and 24 in New York, with a
particular
 
                                       32
<PAGE>   43
 
focus on possible cost savings and synergies. At meetings held on June 30 and
July 1, the parties continued their discussion regarding possible cost savings
and synergies and the impact of the pending IDB litigation and IDB's method of
revenue recognition on the possible exchange ratio structure.
 
     Also during June and July, representatives of LDDS and IDB began exchanging
drafts of the merger agreement and conducting negotiations regarding the terms
of the merger agreement. During this period, various presentations were given by
the management, financial advisors and legal counsel of IDB at meetings of the
IDB Board of Directors held on July 6 and July 11, 1994, at which the results of
the due diligence investigations and the status of the merger negotiations were
discussed and reviewed. In addition, the presentations given by the financial
advisors to IDB addressed the status and preliminary results of the analyses
providing the basis for their respective fairness opinions. The financial
advisors provided information regarding the proposed exchange ratio structure,
stock price performance for LDDS and IDB and preliminary comparative valuations
of LDDS, IDB and other telecommunications companies based upon various
multiples, growth rates and similar factors. Mr. Ebbers advised certain
individual members of the LDDS Board of Directors from time to time of the
status of due diligence discussions with IDB during this period as well.
 
     On July 25, officers and management of LDDS and IDB and representatives of
Breckenridge and Hambrecht & Quist mutually agreed to meet in St. Louis to
discuss a definitive exchange ratio range for the proposed merger. As a result
of due diligence investigations, the representatives of LDDS and IDB discussed
adjustments to the exchange ratio range previously proposed at the Denver
meeting based on factors such as IDB's revenue recognition policies, pending
litigation regarding IDB, growth expectations of both companies and reserve
adjustments of IDB.
 
     As the exchange of information and negotiations between LDDS and IDB
proceeded during June and July, IDB received unsolicited inquiries from two
other telecommunications companies regarding possible business combinations. A
third telecommunications company approached management of IDB regarding the
possibility of an equity investment in IDB. Mutual confidentiality agreements
were entered into with all three of these companies and, thereafter, certain
members of IDB management and IDB's financial advisors met with their
representatives and IDB provided these companies with public and non-public
information relating to IDB's operations and other matters. The information
provided to these companies included documents relating to IDB's corporate
organization, capitalization, financial statements and reports (including
reports filed with the Commission), employees, benefit plans, contracts,
licenses, permits, litigation and property. IDB did not commence any due
diligence examination of these companies nor did it receive any non-public
information from them. However, in the course of the three companies' diligence
investigations, IDB held preliminary discussions with each of these entities
about the possible terms of a business combination or investment in IDB. No
formal offers or proposals were ultimately received by IDB, although IDB
expressed its willingness to discuss any offers or proposals.
 
     In addition to considering these possible business combinations or
investments, IDB's Board of Directors analyzed the possibility of remaining
independent as an alternative to the proposed merger. The IDB Board believed,
however, that Deloitte's resignation would likely have an adverse impact on
IDB's ability to raise capital, and, as a result, IDB's rate of growth. The fall
in the market value of IDB's Common Stock after the announcement of Deloitte's
resignation, the resulting litigation and expected future operating results of
IDB raised concerns regarding the impact that such events would have on IDB's
long term value and marketability. In light of these factors, the IDB Board of
Directors believed that the consolidated organization provided its stockholders
with an opportunity to participate in a telecommunications company with greater
future prospects than IDB alone.
 
     By July 25, 1994, negotiation of the Merger Agreement was substantially
complete, and each company and their advisors prepared additional information to
present to their respective Boards of Directors. On July 26, 1994, additional
information regarding the Merger was distributed to the Board of Directors of
LDDS by Breckenridge and LDDS's management, and on July 28, 1994, the LDDS Board
met and discussed, among other things, the details of the proposed Merger
Agreement. All of the members of the LDDS Board were present at such meeting,
except John W. Kluge and Stiles A. Kellett, Jr., who were absent due to
out-of-town
 
                                       33

commitments. At such meeting, Breckenridge presented its analysis of the Merger
and delivered its oral opinion to the Board of Directors (which it subsequently
confirmed in writing) to the effect that, based upon the facts and circumstances
as they existed at that time and subject to the various assumptions and other
considerations set forth in such opinion, as of July 28, 1994, the proposed
Exchange Ratio was fair from a financial point of view to the holders of LDDS
Common Stock and LDDS Preferred Stock. In addition, members of LDDS management
made a presentation to the Board regarding the terms of the proposed Merger, the
business reasons for approving the Merger and the increased revenue impact from
the right to return traffic revenues that were anticipated to be generated from
IDB's international operating agreements. During and following Breckenridge's
and management's presentations, questions were asked by members of LDDS's Board
and answered by representatives of Breckenridge and management regarding
financial issues, including accounting matters, the potential impact of
developments on the financial markets, consideration of the possible sale of
assets of IDB and the valuation thereof, personnel matters, the circumstances
surrounding the change in IDB's accountants, the accounting policies of IDB
relating to revenue recognition, pending litigation relating to IDB, and other
matters. The Board also reviewed the proposed Merger Agreement (the final terms
of which are described more fully elsewhere in this Joint Proxy
Statement/Prospectus) and, following the presentations and discussions described
above, all of the directors present concluded that the Merger was fair and in
the best interest of LDDS and its shareholders and unanimously approved the
Merger Agreement and the transactions contemplated thereby and authorized
officers of LDDS to execute the Merger Agreement, which approval was
subsequently joined in by Messrs. Kluge and Kellett and ratified by the entire
Board of LDDS.
 
     On July 28 and July 29, 1994, the Board of Directors of IDB met to consider
the proposed Merger Agreement and the transactions contemplated thereby. Members
of IDB's management and representatives of each of Hambrecht & Quist, Chemical
and IDB's legal counsel presented written materials and made presentations to
the Board of Directors of IDB and discussed with members of the IDB Board their
views and analyses of various aspects of the proposed Merger and the effects
thereof. Representatives of Hambrecht & Quist and Chemical also delivered their
oral opinions to the Board of Directors (which were later confirmed in writing)
that the proposed Exchange Ratio is fair, from a financial point of view, to the
holders of IDB Common Stock. The Board of Directors of IDB reviewed the proposed
terms of the Merger Agreement and, following significant discussion, concluded
that the Merger was in the best interest of IDB and its stockholders and, by a
unanimous vote of all directors, approved the Merger Agreement and the
transactions contemplated thereby and authorized officers of IDB to enter into
the Merger Agreement. On August 1, 1994, LDDS and IDB executed the Merger
Agreement and issued a joint press release announcing the Merger following the
close of trading on the Nasdaq National Market. See "-- Reasons For the Merger;
Board Recommendations" and "-- Opinions of Financial Advisors."
 
     On August 22, 1994, LDDS announced that it had entered into a definitive
agreement to acquire WilTel for $2.5 billion in cash. LDDS expects to finance
this acquisition and refinance certain other debt through a new $3.41 billion
credit facility. The announcement of the WilTel Acquisition gave rise, under the
terms of the Merger Agreement, to a right on the part of IDB's Board of
Directors to reevaluate the Merger in light of the WilTel Acquisition and to
determine whether or not it was in the best interest of IDB's stockholders to
proceed. Following the announcement of the WilTel Acquisition, representatives
of IDB, its counsel and financial advisors conducted limited legal and business
due diligence reviews of WilTel, the proposed WilTel Acquisition and the related
financing arrangements. At meetings held on September 1, 1994 and September 19,
1994, the WilTel Acquisition and the results of those due diligence reviews were
presented to the Board of Directors of IDB. At the September 19, 1994 IDB Board
meeting, representatives of each of Hambrecht & Quist and Chemical reconfirmed
their opinions based upon facts known to them on that date, including the
possibility of the WilTel Acquisition, that the proposed Exchange Ratio is fair,
from a financial point of view, to the holders of IDB Common Stock. After a
thorough discussion of the WilTel Acquisition, including the impact of its
financing on the future prospects of LDDS, the Board of Directors of IDB, by a
unanimous vote of all directors, reconfirmed its approval of the Merger
Agreement and the transactions contemplated thereby and authorized officers of
IDB to proceed with the Merger and related transactions whether or not the
WilTel Acquisition was consummated.
 
                                       34
<PAGE>   45
 
     Representatives of Hambrecht & Quist and Chemical attended or participated
via telephone in the meetings of IDB's Board of Directors held in July and
September of 1994 to consider the Merger. At each of these meetings, IDB Board
members queried the financial advisors at various times about, among other
topics, the timing of the Merger, the proposed pricing structure for the Merger,
the different valuation analyses presented, including the selection of
comparable companies and other technical aspects and characteristics of certain
approaches, the impact of changes to IDB's method of accounting for
international long distance traffic, post-Merger operating concerns, whether or
not the WilTel Acquisition is consummated, and the status of discussions and
meetings, if any, with third parties. At these meetings, the advisors discussed
their analyses and answered questions. Such discussions and answers were
supportive of, and ultimately based upon, the contents of the financial
advisors' opinions, as more fully described below.
 
     The WilTel Acquisition, if consummated, is expected to provide the combined
organization an opportunity to lower significantly its cost of providing
services to customers because it will own, rather than lease, domestic transport
facilities. In addition, WilTel's international traffic could utilize IDB's
international facilities, which provides the opportunity to further reduce costs
for the combined organization. WilTel's domestic revenue is also expected to
provide the opportunity for the combined organization to increase operating
efficiencies by reducing redundant selling, general and administrative costs.
There can be no assurance, however, that any of these efficiencies or
opportunities will be achieved.
 
REASONS FOR THE MERGER; BOARD RECOMMENDATIONS
 
     In reaching their decision to approve the Merger Agreement, the Boards of
Directors of each of LDDS and IDB consulted with their respective management
teams and advisors and independently considered the proposed Merger Agreement,
including the material factors described below. Based upon their respective
independent reviews of such factors and the business and operations of the other
party, the Boards of Directors of LDDS and IDB each approved the Merger
Agreement and the transactions contemplated thereby. There can be no assurance,
however, that any of the efficiencies or opportunities described in the
following reasons for the Merger will be achieved through the consummation of
the Merger.
 
  LDDS's Reasons for the Merger
 
     In its deliberations with regard to the Merger, the Board of Directors of
LDDS considered the respective businesses, financial conditions, historical and
projected results of operations, geographic markets and growth prospects of LDDS
and IDB (the "Companies"), as well as the terms and conditions of the proposed
Merger Agreement, and the anticipated accounting and federal tax treatment of
the Merger. The Board of Directors also considered the oral opinion rendered by
Breckenridge (which it subsequently confirmed in writing) to the effect that,
based upon the facts and circumstances as they existed at the time and subject
to the various assumptions and other considerations set forth in such opinion,
as of July 28, 1994, the Exchange Ratio was fair from a financial point of view
to the holders of LDDS Common Stock and LDDS Preferred Stock. The LDDS Board of
Directors did not find it practical to and did not quantify or attempt to attach
relative weights to the specific factors considered by it. Based upon the
foregoing, the Board of Directors of LDDS approved the Merger as being fair,
including, without limitation, from financial and structural points of view, and
in the best interest of LDDS and its shareholders, and reached the conclusions
described below.
 
          1. THE MERGER IS EXPECTED TO ENHANCE LDDS'S OPPORTUNITIES FOR FURTHER
     GROWTH.  With pro forma consolidated 1993 revenues in excess of $2.0
     billion (excluding the WilTel Acquisition), the consolidation of IDB with
     LDDS is expected to enhance LDDS's current position, based on actual 1993
     revenues, as one of the largest long distance telecommunications companies
     in the industry, serving customers domestically and internationally. Based
     on FCC statistics as of December 31, 1993, LDDS's share of total toll
     service revenues for 1993 was 1.5%. As a stronger competitor in the long
     distance telecommunications industry, LDDS believes it should be in a
     better position to execute its four-point growth strategy, which consists
     of internal growth, the selective acquisition of smaller long distance
     carriers with limited geographic service areas and market shares, the
     consolidation of certain third tier long distance carriers with larger
     market shares and international expansion. With respect to internal growth,
     LDDS expects that the expanded customer base of the consolidated
     organization will permit it to offer more services to a
 
                                       35
<PAGE>   46
 
     broader range of customers, including those requiring significant
     international telecommunications needs, and to penetrate the current
     markets of the Companies more effectively. LDDS also expects that the
     consolidated organization, with its increased financial resources and
     greater access to capital markets, should have enhanced capabilities to
     make selective acquisitions of smaller long distance companies and to
     effect consolidations of certain third tier long distance carriers and that
     the consolidated organization, with its increased asset and market base,
     should be able to assimilate these carriers more effectively following the
     completion of such transactions. The consolidated organization should also
     be a significant international long distance telecommunications provider
     with direct terminating agreements and facilities in over sixty countries,
     thereby allowing for further international expansion.
 
          2. THE MERGER IS EXPECTED TO PROVIDE THE OPPORTUNITY FOR SIGNIFICANT
     COST SAVINGS FOR THE COMBINED ORGANIZATION.  Based on LDDS's review and
     analysis of various opportunities to consolidate the operations of LDDS and
     IDB and on discussions with management of IDB, management of LDDS believes
     that significant savings could be achieved from the realization of
     economies of scale resulting from networking and operating efficiencies.
     Networking efficiencies should permit, among other things, (i) greater use
     of lower rate fixed-cost international facilities; (ii) greater realization
     of inbound international traffic from increased outbound international
     traffic; (iii) greater volume discounts on usage sensitive facilities; (iv)
     the elimination of certain switch locations; and (v) greater utilization of
     owned and leased network capacity. With regard to operational efficiencies,
     it is expected that the consolidated organization will be able to eliminate
     certain functional and contractual duplication resulting from the Merger,
     such as by consolidating management information services functions,
     eliminating lease contract obligations and reducing duplicative personnel.
 
          3. THE MERGER IS EXPECTED TO CREATE GREATER LIQUIDITY FOR THE
     SHAREHOLDERS OF THE COMBINED ORGANIZATION.  The market capitalization of
     LDDS at July 27, 1994 was approximately $3.0 billion (excluding the value
     of outstanding LDDS Preferred Stock). Upon consummation of the Merger, the
     consolidated organization will have a market capitalization of
     approximately $3.8 billion (excluding the value of outstanding LDDS
     Preferred Stock) based upon the market value of LDDS Common Stock on July
     27, 1994 of $18.75 per share. Accordingly, management of LDDS believes
     that, after the Merger, holders of LDDS Common Stock will have greater
     liquidity than is presently available for shares of LDDS Common Stock.
     Because the Merger will create a consolidated organization with
     significantly greater assets, revenues and cash flow as compared to either
     of the Companies on a stand-alone basis, LDDS believes that the
     consolidated organization will enjoy improved access to capital markets.
 
  Recommendation of LDDS's Board of Directors
 
     AT THE DIRECTORS' MEETING HELD TO CONSIDER THE MERGER, THE DIRECTORS OF
LDDS PRESENT CAREFULLY CONSIDERED AND UNANIMOUSLY APPROVED THE TERMS OF THE
MERGER AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY AS BEING FAIR AND IN
THE BEST INTEREST OF LDDS AND ITS SHAREHOLDERS. THE LDDS BOARD OF DIRECTORS
UNANIMOUSLY RECOMMENDS THAT THE SHAREHOLDERS VOTE "FOR" THE PROPOSAL TO APPROVE
THE ISSUANCE OF LDDS COMMON STOCK PURSUANT TO THE MERGER AGREEMENT.
 
  IDB's Reasons for the Merger
 
     At meetings of IDB's Board of Directors held in July of 1994, the IDB Board
received presentations from, and reviewed the proposed terms and conditions of
the Merger with, IDB's senior officers and its legal counsel and financial
advisors. In its deliberations concerning the Merger, the IDB Board considered,
without assigning relative weights to, a number of factors, including the
following: (i) LDDS's business, assets, management, competitive position and
prospects; (ii) the financial condition, results of operations and cash flows of
LDDS, both on a historical and on a prospective basis, before and after giving
effect to the Merger; (iii) the terms and conditions of the proposed Merger,
including the nature and value of the consideration to be paid by LDDS; (iv) the
likelihood that, for federal income tax purposes, no gain or loss will be
recognized by IDB stockholders with respect to the LDDS stock received in
exchange for their IDB Common Stock;
 
                                       36
<PAGE>   47
 
(v) the potential impact on IDB's ability to raise capital and participate in
any consolidation of the telecommunications industry of certain pending
litigation and investigations and of IDB's recent operating results; and (vi)
the opinions of Hambrecht & Quist and Chemical as to the fairness, from a
financial point of view, of the Exchange Ratio to the holders of IDB Common
Stock. At meetings held in September of 1994, the IDB Board reconsidered all of
the foregoing factors in light of the proposed acquisition by LDDS of WilTel
and, in addition, considered the impact of the indebtedness to be incurred to
finance the WilTel Acquisition on the consolidated organization and its
prospects. Based upon its deliberations, the IDB Board approved the Merger, and
reconfirmed that approval in light of the WilTel Acquisition, by unanimous vote,
and determined that, whether or not the WilTel Acquisition is consummated:
 
     THE MERGER OFFERS IDB AND ITS STOCKHOLDERS AN ATTRACTIVE OPPORTUNITY TO
CONTINUE AS STOCKHOLDERS OF A CONSOLIDATED ORGANIZATION WITH ENHANCED FINANCIAL
AND MARKET STRENGTH.  Based on 1993 revenues, as reported by the FCC, the Merger
would create one of the largest U.S. based long distance telecommunications
companies in the industry that could be expected to compete more effectively in
national and world markets than IDB alone. The consolidated organization would
have pro forma consolidated 1993 revenues in excess of $2.0 billion (excluding
the WilTel Acquisition). The Board of Directors of IDB believes that the
resulting enhanced financial and operational strength will increase
opportunities for growth as a consolidated organization and will offer greater
flexibility in meeting the challenges confronting the telecommunications
industry, such as technological innovation, intensifying competitive pressures
and industry consolidation. A combination with LDDS represents a means of
affording to IDB's stockholders the benefits of continuing IDB's long-term
growth strategy in light of the uncertainties inherent in current economic,
legal and competitive conditions.
 
     THE MERGER OFFERS SIGNIFICANT POTENTIAL FOR OPERATING EFFICIENCIES AND COST
SAVINGS.  The Board of Directors of IDB believes that the Merger offers IDB and
LDDS an opportunity to improve their profitability through the achievement of
economies of scale and the elimination of redundancies. Numerous operating and
financial synergies are expected to result from the combination because of the
benefit to LDDS from an international network and the benefit to IDB from
additional domestic traffic to feed its international network. The anticipated
increase in international traffic from the consolidated organization should
lower the consolidated organization's international rates and should increase
international return traffic. Additional savings should also be realized by
processing IDB's domestic traffic through the domestic system of LDDS. A
combination with LDDS would be expected to reduce duplicative costs such as
administrative personnel, public company expenses and billing system expenses.
The IDB Board of Directors also believes that a combination with LDDS should
help marketing and sales efforts and should enable the consolidated organization
to provide more cost effective products and services. It is anticipated that the
consolidated organization will be able to market IDB's international services to
LDDS's existing retail customers and IDB's customers will be offered a greater
network of services and products from the consolidated organization.
 
     THE WILTEL ACQUISITION IS EXPECTED TO AMPLIFY THE BENEFITS TO IDB
STOCKHOLDERS OF THE MERGER BY FURTHER ENHANCING THE CONSOLIDATED ORGANIZATION'S
FINANCIAL AND OPERATIONAL STRENGTH AND PROVIDING ADDITIONAL OPPORTUNITIES FOR
EFFICIENCIES AND COST SAVINGS. The IDB Board believes that the WilTel
Acquisition and the resulting combination of LDDS, IDB and WilTel will create an
even stronger consolidated organization than would be created by the Merger
alone. The company resulting from the Merger and the WilTel Acquisition would
have pro forma consolidated 1993 revenues in excess of $2.6 billion and would
have access to an even larger volume of domestic and international
telecommunications traffic and enhanced network through which to deliver it. In
addition, further cost reductions through the elimination of redundant
administrative functions and duplicative facilities and operations could be
anticipated to result from such a consolidation. In reevaluating the Merger in
light of the WilTel Acquisition, the IDB Board of Directors weighed the
foregoing factors against the substantial increase in debt to be incurred by
LDDS and the limitations on LDDS's future operations that would be imposed by
its proposed credit facilities. On balance, the IDB Board believes that the
WilTel Acquisition would be beneficial and would create a consolidated
organization which would be both stronger as an independent company and more
attractive as an acquisition candidate for other more substantial
telecommunications companies.

  Recommendation of IDB's Board of Directors
 
     FOR THE REASONS DISCUSSED ABOVE, THE BOARD OF DIRECTORS OF IDB UNANIMOUSLY
APPROVED THE MERGER AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY AS BEING
FAIR AND IN THE BEST INTEREST OF IDB AND ITS STOCKHOLDERS. THE IDB BOARD OF
DIRECTORS UNANIMOUSLY RECOMMENDS THAT IDB STOCKHOLDERS VOTE "FOR" THE APPROVAL
OF THE MERGER AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY, WHETHER OR
NOT THE WILTEL ACQUISITION IS CONSUMMATED. IF SO APPROVED, THE MERGER MAY BE
EFFECTED WITHOUT REGARD TO WHETHER THE WILTEL ACQUISITION IS CONSUMMATED.
 
OPINIONS OF FINANCIAL ADVISORS
 
  LDDS
 
     LDDS retained Breckenridge to act, among other things, as financial adviser
to LDDS in connection with the Merger. On July 28, 1994, in connection with the
evaluation of the Merger by the Board of Directors of LDDS, Breckenridge made a
presentation to the Board of Directors with respect to the Merger and rendered
its oral opinion to the Board of Directors of LDDS (which it subsequently
confirmed in writing) to the effect that, based upon the facts and circumstances
as they existed at that time and subject to the various assumptions and other
considerations set forth in such opinion, as of July 28, 1994, the Exchange
Ratio was fair from a financial point of view to the holders of LDDS Common
Stock and LDDS Preferred Stock. No limitations were imposed by LDDS on the scope
of Breckenridge's investigation or the procedures followed by Breckenridge in
rendering its opinion.
 
     The full text of the written opinion of Breckenridge dated as of July 28,
1994, which sets forth assumptions made, matters considered, and limitations on
the review undertaken, is attached as Appendix B to this Joint Proxy
Statement/Prospectus. Holders of LDDS Common Stock and LDDS Preferred Stock are
urged to read this opinion in its entirety. Breckenridge's opinion is directed
only to the Exchange Ratio and does not constitute a recommendation to any
holder of LDDS Common Stock or LDDS Preferred Stock as to how such holder should
vote at the LDDS Special Meeting. The summary of the opinion of Breckenridge set
forth in this Joint Proxy Statement/Prospectus is qualified in its entirety by
reference to the full text of such opinion. Under the terms of the Merger
Agreement, Breckenridge is not required to render any oral or written opinion
regarding the fairness of the Exchange Ratio as of any date after July 28, 1994;
however, LDDS is not obligated to consummate the Merger if such opinion shall
have been withdrawn at or prior to the LDDS Special Meeting. See "-- Terms and
Conditions of the Proposed Merger -- LDDS's Conditions."
 
     In rendering its written opinion, Breckenridge reviewed and analyzed: (i)
certain publicly available financial and other information concerning LDDS and
IDB, (ii) certain internal financial statements, including IDB management's
estimates of the restated results of operations for IDB for the quarter ended
March 31, 1994 (which estimates were made available to Breckenridge prior to
July 28, 1994), and other financial and operating data concerning LDDS and IDB
prepared by respective managements of LDDS and IDB, (iii) certain financial
projections prepared by the respective managements of LDDS and IDB, including
income statement projections and certain supporting assumptions, for fiscal
years 1994 and 1995, presented on a quarterly basis, (iv) current and historical
reported market prices and trading activity for the LDDS Common Stock and the
IDB Common Stock, (v) a comparison of the financial performance of LDDS and IDB
and the prices and trading activity of the LDDS Common Stock and the IDB Common
Stock with the financial performance of certain other comparable publicly traded
companies and their securities, (vi) the financial terms of certain recent
business combinations in the telecommunications industry that Breckenridge
deemed relevant, (vii) certain assumptions prepared jointly by the managements
of LDDS and IDB concerning potential cost savings that could be achieved from
the realization of economies of scale resulting from networking and operating
efficiencies (the "Savings Assumptions"), and (viii) the Merger Agreement and
certain related documents. In addition, Breckenridge engaged in discussions with
the management of LDDS and IDB concerning their respective businesses, assets,
liabilities, condition (financial and otherwise) and prospects and performed
such other studies and analyses and reviewed such other information as it
 
                                       38
<PAGE>   49
 
considered appropriate. In rendering its written opinion, Breckenridge did not
review or analyze the WilTel Acquisition or other facts and circumstances
existing or arising after July 28, 1994, the date of its written opinion.
 
     In connection with rendering its written opinion, Breckenridge performed a
variety of financial analyses, including those summarized below. The summary set
forth below does not purport to be a complete description of the analyses
performed by Breckenridge. The preparation of a fairness opinion involves
various determinations as to the most appropriate and relevant methods of
financial analysis and the application of those methods to the particular
circumstances and, therefore, such an opinion is not readily susceptible to
summary description. Furthermore, in arriving at its opinion, Breckenridge did
not attribute any particular weight to any analysis or factor considered by it,
but rather made qualitative judgments as to the significance and relevance of
each analysis and factor. Accordingly, Breckenridge believes that such analyses
and the summary set forth below must be considered as a whole and that
considering portions of its analyses and the factors considered, without
considering all analyses and factors, could create an incomplete or misleading
view of the process underlying its opinion.
 
     In performing its analyses, Breckenridge made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of LDDS and IDB. The
analyses performed by Breckenridge are not necessarily indicative of actual
values or future results, which may be significantly more or less favorable than
suggested by such analyses. The analyses were prepared for the purpose of
enabling Breckenridge to render its opinion as to the fairness of the Exchange
Ratio to the holders of the LDDS Common Stock and the LDDS Preferred Stock and
do not purport to be appraisals or to reflect the prices at which a company or
its securities might actually be sold. In addition, as described above,
Breckenridge's opinion and presentation to the LDDS Board of Directors was one
of many factors taken into consideration by the Board of Directors of LDDS.
Consequently, the Breckenridge analyses described below should not be viewed as
determinative of the LDDS Board's or LDDS management's opinion with respect to
the value of LDDS or whether the LDDS Board or LDDS management would have been
willing to agree to a different Exchange Ratio.
 
     Pro Forma Merger Analysis.  The effect of the Merger on the financial
projections of LDDS were analyzed. Breckenridge compared the financial
projections of LDDS on a stand-alone basis for the fiscal year ending December
31, 1995 to the pro forma financial projections for the consolidated
organization resulting from the Merger for the fiscal year ending December 31,
1995. This analysis showed that (i) the Merger would be accretive to LDDS's
projected earnings per share for the fiscal year ending December 31, 1995, the
first full fiscal year after consummation of the Merger, by an amount ranging
from $0.02 to $0.05 per share depending on the Exchange Ratio and (ii) the
holders of LDDS Common Stock (assuming the exercise of certain outstanding stock
options to purchase IDB Common Stock as a result of the Merger) would own from
between 78.2% to 80.5% of the fully-diluted equity of the consolidated
organization resulting from the Merger. This analysis was based primarily on the
respective financial projections of the managements of LDDS and IDB and the
Savings Assumptions, which Savings Assumptions indicated that significant
potential cost savings and synergies could be achieved from the realization of
economies of scale resulting from networking and operating efficiencies;
however, no assurance can be given that such cost savings and synergies will be
realized. The actual results achieved by the consolidated organization resulting
from the Merger may vary from the projected results and variations may be
material.
 
     Analysis of Selected Transactions.  Breckenridge reviewed publicly
available information relating to 23 public and private market sales and
proposed investment transactions of selected long distance telecommunications
companies occurring during the period from 1986 through 1993. Of the
transactions reviewed, Breckenridge found that four had characteristics most
comparable to the Merger (the "Comparable Transactions") in terms of size of the
proposed transaction and similarity of the businesses of such companies compared
to the businesses of LDDS and IDB. These transactions were: (i) the merger of
LDDS and Advanced Telecommunications Corporation ("ATC"); (ii) the merger of
LDDS, MCC and Resurgens; (iii) the anticipated purchase of approximately 21.7%
of MCI Telecommunications Corporation ("MCI") by British Telecom PLC; and (iv)
the anticipated purchase of approximately 20.0% of Sprint Corporation ("Sprint")
by Deutsche Bundespost Telekom and France Telecom. Breckenridge compared the
multiples of purchase price to be paid in connection with these transactions to
forecasted revenues, earnings before income
 
                                       39
<PAGE>   50
 
taxes, depreciation and amortization ("EBITDA"), and earnings with the
comparable multiples under the terms of the Merger Agreement. Breckenridge
determined that, as of July 28, 1994, based on the market price of the LDDS
Common Stock on July 28, 1994 and considering IDB management's estimates of the
restated results of operations for IDB for the quarter ended March 31, 1994, (i)
the range of purchase price to forecasted revenue for the Comparable
Transactions was from 1.54 to 2.12 and the average was 1.73 and that the
corresponding multiple established in the Merger was between 1.10 and 1.27; (ii)
the range of purchase price to forecasted EBITDA for the Comparable Transactions
was 6.43 to 12.24 and the average was 8.46 and that the corresponding multiple
established in the Merger was between 10.54 to 12.16; and (iii) the range of
purchase price to forecasted earnings for the Comparable Transactions was 16.16
to 30.59 and the average was 22.58 and that the corresponding multiple
established in the Merger was between 32.71 to 37.75. Based on its analysis of
the business and operations of LDDS and IDB and the Savings Assumptions,
Breckenridge noted that (i) the multiple of purchase price to forecasted
earnings established in the Merger was higher than the range of multiples of
purchase price to forecasted earnings established in the Comparable Transactions
and (ii) the range of multiples of purchase price to forecasted revenue
established in the Merger was below the range of such multiples established in
the Comparable Transactions and that the range of multiples of purchase price to
forecasted EBITDA established in the Merger was within the range of such
multiples relating to the Comparable Transactions. Breckenridge considered in
its analysis certain operating efficiencies expected to result in connection
with the Merger and therefore placed more emphasis on the multiples of purchase
price to forecasted revenue and EBITDA than the multiples of purchase price to
forecasted earnings. As a result, Breckenridge determined that this analysis
taken as a whole supported the Exchange Ratio set forth in the Merger Agreement.
 
     Because the reasons for the circumstances surrounding each of the
Comparable Transactions were specific to each such transaction and because of
the inherent differences between the business, operations and prospects of LDDS
and IDB and the businesses, operations and prospects of the companies analyzed
in connection with the Comparable Transactions, Breckenridge believes that it
was inappropriate to, and therefore did not, rely solely on the quantitative
results of the analysis and, accordingly, made certain qualitative judgments
concerning such differences.
 
     Historical Performance and Contribution Analysis.  Breckenridge compared
LDDS to IDB on a historical financial basis for the twelve months ended December
31, 1993, the fiscal quarter ending March 31, 1994 and forecasted information
for the fiscal year ending December 31, 1994 prepared by the managements of LDDS
and IDB, adjusted, in each case, for IDB management's estimates of the restated
results of operations for IDB for the quarter ended March 31, 1994. For each of
these periods, Breckenridge also analyzed the relative contributions of each of
LDDS and IDB to the pro forma revenue, EBITDA, net income and book value of the
consolidated organization. Based on such analysis, Breckenridge determined that
LDDS's average contributions for these periods to the pro forma revenue, EBITDA,
net income and book value of the consolidated organization were 75.17%, 83.03%,
87.53%, 84.23% respectively. The results of such analysis were then compared to
the pro forma ownership percentage of holders of LDDS Common Stock (assuming the
exercise of certain outstanding stock options to purchase IDB Common Stock as a
result of the Merger) in the consolidated organization of between 78.2% and
80.5%. Breckenridge determined that, based on Breckenridge's analysis of the
results of operations and prospects of LDDS and IDB and the Savings Assumptions,
these analyses taken as a whole supported the Exchange Ratio set forth in the
Merger Agreement.
 
     Discounted Cash Flow.  Breckenridge used the discounted cash flow method to
estimate, under discount rate assumptions of 10%, 11% and 12%, and based upon
projections of after-tax free cash flow for the consolidated organization
resulting from the Merger prepared by the managements of LDDS and IDB, the
values of the consolidated organization based upon (i) the present value of the
after-tax free cash flow that the consolidated organization could produce over a
five-year period from 1995 through 1999 and (ii) the terminal value of the
consolidated organization at the end of such period assuming multiples of 10x,
11x and 12x projected 1999 EBIT. Breckenridge also estimated the value of LDDS
on a stand-alone basis using the discounted cash flow method under the same
discount rate assumptions described in the preceding sentence. The values per
share calculated for the consolidated organization under the foregoing analyses
ranged from
 
                                       40
<PAGE>   51
 
$25.56 to $33.97, whereas the values per share calculated for LDDS on a
stand-alone basis ranged from $20.11 to $25.82. Based on this analysis,
Breckenridge determined that, based on the Exchange Ratio set forth in the
Merger Agreement, if the Merger were consummated, per share values for the
consolidated organization resulting from the Merger under the foregoing analysis
would generally be higher than for LDDS on a stand-alone basis if the Merger
were not consummated.
 
     Analysis of Publicly Traded Comparable Companies.  Breckenridge reviewed
and compared certain actual and estimated financial and stock market information
of LDDS, IDB and selected publicly traded long distance telecommunication
companies, including AT&T Communications, Inc. ("AT&T"), MCI, Sprint, ALC
Communications Corp. ("ALC") and LCI International, Inc. ("LCI") (collectively,
the "Comparable Companies"). Breckenridge's analysis indicated that, as of July
28, 1994, the market price of shares, (i) as multiples of 1993 earnings and
estimated 1994 earnings, ranged from 17.3x to 33.2x and 15.7x to 20.5x,
respectively, for the Comparable Companies compared to multiples of 22.2x and
18.0x, respectively, for LDDS and 31.4x and 25.9x, respectively, for IDB; and
(ii) as a multiple of book value, ranged from 3.2x to
5.3x for the Comparable Companies compared to a multiple of 1.6x for LDDS and
2.4x for IDB, taking into account adjustments for IDB management's estimates of
the restated results of operations for IDB for the quarter ended March 31, 1994.
The analysis further indicated the total value (defined as market capitalization
plus the principal amount of outstanding debt plus the book value of preferred
stock, if any, less cash) of the Comparable Companies as a multiple of estimated
1994 revenue, earnings before interest and taxes ("EBIT") and EBITDA ranged from
1.10x to 2.24x, 9.75x to 12.84x and 5.60x to 10.87x, respectively, as compared
to multiples of 2.05x, 11.52x and 8.25x for LDDS and 1.64x, 9.50x and 6.57x for
IDB, taking into account adjustments for IDB management's estimates of the
restated results of operations for IDB for the quarter ended March 31, 1994.
Breckenridge conducted this analysis and provided it to the Board of Directors
of LDDS for informational purposes only; this analysis was not given significant
weight by Breckenridge in rendering its written opinion, primarily because
Breckenridge believed that the market price of shares of the Comparable
Companies were influenced by many factors that would not be relevant in a change
of control transaction such as the Merger. The estimated 1994 earnings were
based on the mean of publicly available earnings estimates made by research
analysts provided by the Institutional Brokers Estimate System.
 
     No company or transaction used in the analyses of selected transactions or
in the comparison with other telecommunications companies summarized above is
identical to LDDS, IDB or the Merger. Accordingly, an analysis of the results of
the foregoing is not mathematical; rather it involves complex determinations and
judgments concerning differences in financial and operating characteristics and
other factors that could affect the public trading prices, both before and after
the Merger, of the company or companies to which LDDS and IDB are being
compared. The various ranges of multiples, discount rates and growth rates used
in the analyses described above were chosen to reflect the growth prospects and
relative risks of LDDS and IDB and the pro forma consolidated organization
resulting from the Merger and were selected by Breckenridge based on its review
(including discussions with the managements of LDDS and IDB) of the results and
prospects for LDDS, IDB and the consolidated organization resulting from the
Merger and the expertise of Breckenridge in securities valuations generally.
 
     Breckenridge did not independently verify any of the financial or other
information reviewed by it for purposes of its opinion, and it assumed the
accuracy, completeness and fairness of all such information. With respect to the
financial projections for LDDS and IDB and the Savings Assumptions, Breckenridge
assumed that they were reasonably prepared on bases reflecting the best
currently available judgments and estimates of the managements of LDDS and IDB
as to the future financial performance of their respective companies.
Breckenridge also assumed that, in the course of obtaining the necessary
regulatory and governmental approvals for the Merger or in connection with any
change in applicable law, no restriction would be imposed on the surviving
corporation in the Merger that would have a material adverse effect on the
business of the surviving corporation in the Merger or the contemplated benefits
of the Merger, including those contemplated by the Savings Assumptions.
Breckenridge has not made an independent evaluation or appraisal of the assets
of LDDS and IDB, nor has it been furnished with any such appraisal. In addition,
with LDDS's permission, Breckenridge did not independently appraise any
potential or pending litigation involving IDB or LDDS.

Breckenridge's opinion was based on economic, market and other conditions
existing, and the information made available to it as of, the date of its
opinion.
 
     Breckenridge is a recognized investment banking firm and, as part of its
investment banking business, is engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions. The Board of Directors
of LDDS selected Breckenridge because of its expertise, its reputation and its
familiarity with LDDS and the long distance communications industry in general.
 
     As compensation for its services, LDDS has agreed to pay Breckenridge
$          , contingent on the consummation of the Merger. In addition, LDDS has
agreed to indemnify Breckenridge for certain liabilities arising out of or in
connection with its services or opinions. The Breckenridge Group, Inc., an
affiliate of Breckenridge ("Breckenridge Group"), and Breckenridge have provided
investment banking services to LDDS since 1988, for which they have received
cash compensation aggregating approximately $6.8 million. In addition, the
principals of Breckenridge Group own in the aggregate options to acquire 287,850
shares of LDDS Common Stock, which options were originally issued to
Breckenridge Group in connection with financial advisory services rendered by
Breckenridge Group to LDDS in previous acquisitions. The options were granted in
each case with exercise prices equal to the fair market value of LDDS Common
Stock on the date of grant. The principals of Breckenridge Group also currently
own 639,445 shares of LDDS Common Stock, which shares were acquired upon the
exercise of options originally issued to Breckenridge Group in connection with
financial advisory services rendered by Breckenridge Group to LDDS. The
principals of Breckenridge Group also own an additional 57,195 shares of LDDS
Common Stock.
 
  IDB
 
     Hambrecht & Quist Incorporated
 
     As described above under the heading "Background of the Merger," IDB
engaged Hambrecht & Quist to act as its financial advisor in connection with the
Merger and to render an opinion as to the fairness, from a financial point of
view, to IDB's stockholders of the consideration to be received by them in the
Merger. Hambrecht & Quist rendered its oral opinion on July 28, 1994 to the
Board of Directors of IDB, which was subsequently confirmed by a written opinion
dated August 1, 1994, that, as of such date, the consideration to be received by
the holders of IDB Common Stock in the Merger is fair to such holders from a
financial point of view. Following the announcement of the WilTel Acquisition,
Hambrecht & Quist rendered its written opinion dated September 19, 1994, that,
as of such date, the consideration to be received by the holders of IDB Common
Stock in the Merger is fair to such holders from a financial point of view. For
purposes of its opinion, Hambrecht & Quist reviewed and analyzed the Merger both
with and without the WilTel Acquisition. Hambrecht & Quist expressed no opinion
as to the adequacy of any consideration received in the Merger or the WilTel
Acquisition by LDDS or any of its affiliates. A COPY OF HAMBRECHT & QUIST'S
OPINION DATED SEPTEMBER 19, 1994, WHICH SETS FORTH THE ASSUMPTIONS MADE, MATTERS
CONSIDERED, THE SCOPE AND LIMITATIONS OF THE REVIEW UNDERTAKEN AND THE
PROCEDURES FOLLOWED BY HAMBRECHT & QUIST, IS ATTACHED AS ANNEX C TO THIS JOINT
PROXY STATEMENT/PROSPECTUS. IDB'S STOCKHOLDERS ARE ADVISED TO READ THE OPINION
IN ITS ENTIRETY. No limitations were placed on Hambrecht & Quist by the Board of
Directors of IDB with respect to the investigation made or the procedures
followed in preparing and rendering its opinion. Hambrecht & Quist's opinion
addresses only the fairness from a financial point of view to IDB's stockholders
of the consideration to be received in the Merger and is not a recommendation to
any stockholder of IDB as to how to vote at the IDB Special Meeting.
 
     In arriving at its written opinion, among other things, Hambrecht & Quist:
(i) reviewed the publicly available consolidated financial statements of IDB for
recent years and interim periods to date and certain other relevant financial
and operating data of IDB (including its capital structure) made available to
Hambrecht & Quist from published sources and from the internal records of IDB;
(ii) discussed with certain members of the management of IDB the business,
financial condition and prospects of IDB; (iii) reviewed certain financial and
operating information, including certain projections provided by the management
of IDB, relating to IDB and discussed such projections with certain members of
the management of IDB; (iv) reviewed the publicly available consolidated
financial statements of LDDS for recent years and interim
 
                                       42
<PAGE>   53
 
periods to date and certain other relevant financial and operating data of LDDS
(including its capital structure) made available to Hambrecht & Quist from
published sources and from the internal records of LDDS; (v) discussed with
certain members of the management of LDDS the business, financial condition and
prospects of LDDS; (vi) reviewed certain financial and operating information,
including certain projections provided by the management of LDDS, relating to
LDDS (with and without giving effect to the WilTel Acquisition) and discussed
such projections with certain members of the management of LDDS; (vii) reviewed
the recent reported prices and trading activity for the common stock of IDB and
LDDS and compared such information and certain financial information of IDB and
LDDS with similar information for certain other companies engaged in businesses
Hambrecht & Quist considered comparable to those of IDB and LDDS; (viii)
discussed with certain members of the management of WilTel the business,
financial condition and prospects of WilTel; (ix) reviewed certain financial and
operating information, including audited historical financial statements of the
Network Services operations of WilTel and certain projections provided by the
management of WilTel, relating to WilTel and discussed such projections with
certain members of the management of WilTel; (x) discussed with parties other
than LDDS the possibility of a transaction or series of transactions involving a
business combination with IDB; (xi) reviewed the terms, to the extent publicly
available, of certain comparable acquisition transactions; (xii) reviewed the
Agreement; and (xiii) performed such other analyses and examinations and
considered such other information, financial studies, analyses and
investigations and financial, economic and market data as Hambrecht & Quist
deemed relevant.
 
     Hambrecht & Quist has not independently verified any of the information
concerning IDB, LDDS or WilTel considered in connection with its review of the
Merger and, for purposes of its fairness opinion, Hambrecht & Quist has assumed
and relied upon the accuracy and completeness of all such information. Hambrecht
& Quist has not prepared or obtained any independent valuation or appraisal of
the assets or liabilities of IDB, LDDS or WilTel, nor has Hambrecht & Quist
conducted a physical inspection of the properties or facilities of IDB, LDDS or
WilTel. Furthermore, Hambrecht & Quist did not prepare or obtain any evaluation
or appraisal of any potential or pending litigation that may involve IDB, LDDS
or WilTel. In connection with the exchange ratio negotiations, IDB provided
certain financial information, including projections, to representatives of
Hambrecht & Quist. The projections consisted of income statement projections and
certain supporting assumptions by business unit for fiscal years 1994 and 1995
presented on a quarterly basis. The assumptions included information regarding
the number of inbound and outbound minutes and the associated rates. The
original projections were subsequently updated in July principally to reflect
the impact of the change to IDB's method of accounting for international long
distance traffic. These projections were among the materials considered by
Hambrecht & Quist in reaching its opinion. In addition, as part of its analyses,
IDB management, in conjunction with Hambrecht & Quist, prepared balance sheet
and cash flow projections for fiscal years 1994 and 1995 and income statement,
balance sheet and cash flow projections for fiscal years 1996 through 1998. With
respect to the financial forecasts and projections made available to Hambrecht &
Quist and used in its analysis, including estimates of potential benefits
resulting from the Merger, Hambrecht & Quist assumed that they reflect the best
currently available estimates and judgments of the expected future financial
performance of IDB, LDDS and WilTel. For purposes of its opinion, Hambrecht &
Quist assumed that none of IDB, LDDS nor WilTel is a party to any pending
transactions, including external financings, recapitalizations or merger
discussions, other than the Merger, the WilTel Acquisition and those in the
ordinary course of conducting their respective businesses. Hambrecht & Quist has
also assumed that the Merger will qualify as a tax-free reorganization under the
Code and will be accounted for as a pooling of interests. Hambrecht & Quist's
opinion is necessarily based on market, economic, financial and other conditions
as they existed and could be evaluated on the date of its opinion, and any
change in such conditions would require a reevaluation of its opinion. Hambrecht
& Quist expresses no opinion as to the price at which LDDS Common Stock will
trade subsequent to the Effective Time.
 
     In connection with its opinion, Hambrecht & Quist performed a variety of
financial analyses. The following is a summary of financial analyses performed
by Hambrecht & Quist and reviewed with IDB's Board of Directors at or before the
meeting of the Board of Directors of IDB on September 19, 1994, during which
Hambrecht & Quist delivered its written opinion dated September 19, 1994.

     The preparation of a fairness opinion involves various determinations as to
the most appropriate and relevant quantitative and qualitative methods of
financial analyses and the application of those methods to particular
circumstances, and, therefore, such an opinion is not readily susceptible to
summary description. The summary of the Hambrecht & Quist analyses set forth
below does not purport to be a complete description of the presentation by
Hambrecht & Quist to the IDB Board of Directors. In arriving at its opinion,
Hambrecht & Quist did not attribute any particular weight to any analysis or
factor considered by it, but rather made qualitative judgments as to the
significance and relevance of each analysis and factor. Accordingly, Hambrecht &
Quist believes that its analyses and the summary set forth below must be
considered as a whole and that selecting portions of its analyses, without
considering all analyses, or portions of the following summary, without
considering all factors and analyses, could create an incomplete view of the
processes underlying the analyses set forth in the Hambrecht & Quist
presentation to IDB's Board of Directors and its opinion. In performing its
analyses, Hambrecht & Quist made numerous assumptions with respect to industry
performance, general business and economic conditions and other matters, many of
which are beyond the control of IDB and LDDS. In performing its analyses,
Hambrecht & Quist relied upon certain assumptions of potential operating
efficiencies, financial synergies and other items arising out of the Merger,
which were provided by the managements of IDB or LDDS without independent
verification thereof by Hambrecht & Quist. The analyses performed by Hambrecht &
Quist are not necessarily indicative of actual values or actual future results,
which may be significantly more or less favorable than suggested by such
analyses. Additionally, analyses relating to the values of businesses do not
purport to be appraisals or to reflect the prices at which businesses actually
may be sold.
 
     Contribution Analysis.  Hambrecht & Quist analyzed the contribution of each
of IDB and LDDS (both with and without giving effect to the WilTel Acquisition)
to certain income statement and balance sheet categories of the pro forma
consolidated organization, including revenues, EBITDA, EBIT, reported net income
and fully diluted net income. This contribution analysis was then compared to
the pro forma ownership percentage of IDB's and LDDS's stockholders on a fully
diluted basis in the pro forma consolidated organization.
 
     Hambrecht & Quist observed that IDB stockholders are expected to own
approximately 19.7% of the consolidated organization's equity on a fully diluted
basis immediately after the Effective Time, and that LDDS shareholders are
expected to own approximately 80.3% of the consolidated organization's equity
immediately after the Effective Time. For the twelve months ended June 30, 1994,
it was estimated that IDB and LDDS (without giving effect to the WilTel
Acquisition) contributed approximately 21.5% and 78.5%, respectively, of
combined revenues; approximately 10.3% and 89.7%, respectively, of combined
EBITDA; approximately 6.9% and 93.1%, respectively, of combined EBIT;
approximately 4.4% and 95.6%, respectively, of combined reported net income; and
approximately 7.4% and 92.6%, respectively, of combined net income on a fully
diluted basis. For the year ended December 31, 1994, it was estimated that IDB
and LDDS (without giving effect to the WilTel Acquisition) will have contributed
approximately 27.6% and 72.4%, respectively, of combined revenues; approximately
12.6% and 87.4%, respectively, of combined EBITDA; approximately 9.4% and 90.6%,
respectively, of combined EBIT; approximately 10.1% and 89.9%, respectively, of
combined reported net income; and approximately 10.8% and 89.2%, respectively,
of combined net income on a fully diluted basis. For the year ended December 31,
1995, it was estimated that IDB and LDDS (without giving effect to the WilTel
Acquisition) will have contributed approximately 29.1% and 70.9%, respectively,
of combined revenues; approximately 15.0% and 85.0%, respectively, of combined
EBITDA; approximately 16.0% and 84.0%, respectively, of combined EBIT;
approximately 17.1% and 82.9%, respectively, of combined reported net income;
and approximately 17.1% and 82.9%, respectively, of combined net income on a
fully diluted basis.
 
     Assuming the effectiveness of the WilTel Transaction at December 31, 1994,
for the year ended December 31, 1995, it was estimated that IDB and LDDS (giving
effect to the WilTel Acquisition) will have contributed approximately 20.9% and
79.1%, respectively, of combined revenues; approximately 9.9% and 90.1%,
respectively, of combined EBITDA; approximately 11.2% and 88.8%, respectively,
of combined EBIT; approximately 16.1% and 83.9%, respectively, of combined
reported net income; and approximately 16.2% and 83.8%, respectively, of
combined net income on a fully diluted basis. The contribution analysis revealed
that
 
                                       44
<PAGE>   55
 
for the time periods listed above, either giving effect to the WilTel
acquisition or not, the percentage of the consolidated organization's equity on
a fully diluted basis to be received by IDB shareholders (19.7%) exceeds the
percentage contributed by IDB for each of the income statement and balance sheet
categories except for revenues for the twelve months ended June 30, 1994 and the
year ended December 31, 1994.
 
     Analysis of Publicly Traded Comparable Companies.  Hambrecht & Quist
compared various multiples and ratios of income statement categories and
historical balance sheet figures for other publicly traded companies that
Hambrecht & Quist deemed to be comparable to IDB. Such data and ratios included
market capitalization, enterprise value (market capitalization, plus debt, less
cash), enterprise value to historical revenue, enterprise value to historical
EBIT, enterprise value to historical earnings before depreciation, interest and
taxes ("EBDIT"), market capitalization to historical net income, price per share
to historical and projected earnings per share, and earnings per share growth
rates.
 
     Companies used as comparable to IDB included long-distance telephone
companies such as ACC Corp. ("ACC"), ALC, AT&T, LCI, LDDS, MCI and Sprint. The
analysis of comparable companies yielded a mean multiple of 1.8 times historical
revenue, 14.0 times historical EBIT, 11.8 times historical EBDIT, 21.6 times
historical net income, 19.5 times 1994 projected net income and 16.8 times 1995
projected net income. These multiples yielded implied enterprise valuations and
implied equity valuations as follows: multiple of revenue, $735.1 million and
$565.3 million, respectively; multiple of EBIT, $282.7 million and $112.9
million, respectively; and multiple of EBDIT, $526.3 million and $356.4 million,
respectively. The multiples of net income, 1994 projected net income and 1995
projected net income yielded implied equity valuations of $131.3 million, $288.4
million and $621.8 million, respectively. The consideration to be received by
IDB either in the form of equity value or enterprise value exceeds the implied
values yielded by the mean multiples for each of the income statement and
balance sheet categories.
 
     Analysis of Selected Merger and Acquisition Transactions.  Hambrecht &
Quist also reviewed publicly available information on certain mergers and
acquisitions of all or part of certain long-distance telephone companies. In
examining these transactions, Hambrecht & Quist analyzed certain income
statement and balance sheet parameters of the acquired company relative to the
consideration offered. Multiples analyzed included consideration offered for
assets (consideration offered for equity, less cash, plus long term debt, short
term debt and preferred equity) to historical revenue, to historical EBDIT and
to historical EBIT, to historical net operating assets, and consideration
offered for equity to historical net income, to historical book value and
historical cash flow from operations.
 
     The transactions analyzed included the following: Centex Telemanagement/MFS
Communications, Resurgens/LDDS/MCC, TRT Communications/IDB, ATC/LDDS,
Centel/Sprint, World Communications/IDB, Prime Telecommunications/LDDS, Com
Systems/Resurgens, Telecom USA/MCI Communications, Galesi Communications/ATC,
Teleconnect/SoutherNet, Microtel/ATC and SoutherNet/Tel/Man. The consideration
offered in the foregoing transactions was an adjusted mean multiple of 1.6 times
revenue, 12.1 times EBDIT, 16.8 times EBIT, 3.5 times net operating assets, 29.1
times reported net income, 3.8 times book value and 13.3 times cash flow from
operations. These multiples yielded implied enterprise valuations and implied
equity valuations, as follows: multiple of revenue, $650.2 million and $480.3
million, respectively; multiple of EBDIT, $538.7 million and $368.9 million,
respectively; and multiple of EBIT, $340.8 million and $170.9 million,
respectively. The multiples of reported net income and book value yielded
implied equity valuations of $176.5 million and $1,153.6 million, respectively,
and the multiple of cash flow from operations was not meaningful. The
consideration to be received by IDB either in the form of equity value or
enterprise value exceeds the implied values yielded by the mean multiples for
each of the income statement and balance sheet categories except book value.
 
     Discounted Cash Flow Analysis.  Hambrecht & Quist analyzed the theoretical
valuation of IDB based on the unlevered discounted cash flow of the projected
financial performance of IDB, as derived from near term managerial estimates and
analyst estimates. Unlevered free cash flow is derived by taking tax-effected
EBIT, adding non-cash charges for the relevant period (typically depreciation
and amortization), and subtracting other anticipated cash needs for the relevant
periods (typically working capital requirements and capital expenditures). To
estimate the total present value of IDB, before giving effect to its capital
structure,
 
                                       45
<PAGE>   56
 
Hambrecht & Quist discounted to present value (i) the projected stream of
after-tax cash flows and (ii) the terminal value (the hypothetical value derived
by selling the enterprise in its entirety at some future date) of IDB's
business, using discount rates varying from 12.0% to 16.0%. The terminal value
of IDB was based on multiples of 10, 12 and 14 times the projected EBIT for the
1998 fiscal year. At a 12.0% discount rate, the
foregoing analysis yielded implied equity value for IDB of $593.1 million to
$853.2 at a 13.0% discount rate, $564.4 million to $814.2 million; at a 14.0%
discount rate, $537.0 million to $777.0 million; at a 15.0% discount rate,
$510.8 million to $741.6 million; and at a 16.0% discount rate, $485.9 million
to $707.9 million. The consideration to be received by IDB either exceeds or
lies within the implied equity value ranges yielded by the discounted cash flow
analysis.
 
     Pro Forma Analysis.  Hambrecht & Quist analyzed the pro forma impact of the
Merger on IDB's earnings per share, consolidated capitalization and financial
ratios, both with and without giving effect to the WilTel Acquisition. In
conducting its analysis, Hambrecht & Quist relied upon the financial projections
provided by the managements of IDB, LDDS and WilTel, respectively, including a
range of potential savings during the forecast period resulting from the Merger
as estimated by the managements of IDB and LDDS. The analysis indicated that
earnings per share of the pro forma consolidated organization would be higher
after the Merger than for IDB as a stand-alone company and that the Merger is
expected to be accretive for the stockholders of IDB, in each case both with and
without giving effect to the WilTel Acquisition.
 
     Stock Trading History Analysis.  Hambrecht & Quist examined the history of
the trading prices and volume of shares of IDB Common Stock, and the
relationship between movements in the prices of such shares and movements in
certain stock indices, including a telecommunications index, the Nasdaq Index
and the Dow Jones Industrial Average, during the periods from September 15, 1992
to September 14, 1994. Such data were used to analyze the historic public market
valuation of IDB as compared with the historic public market valuation of the
companies comprising the three indices.
 
     No company or transaction used in the above analyses is identical to IDB,
LDDS or the Merger. Accordingly, an analysis of the results of the foregoing is
not mathematical; rather it involves complex considerations and judgments
concerning differences in financial and operating characteristics of the
companies and other factors that could affect the public trading values of the
companies or company to which they are compared. The companies included in the
telecommunications index included IDB, LDDS, ACC, ALC, AT&T, LCI, LDDS, MCI and
Sprint. That the IDB shareholders will continue to hold shares of a
telecommunications company, and that historically telecommunications companies
outperformed the Dow Jones Industrial Average and the Nasdaq Index, although not
a primary or determining factor, helped to support the opinion of Hambrecht &
Quist.
 
     The foregoing description of Hambrecht & Quist's opinion is qualified in
its entirety by reference to the full text of such opinion, which is attached at
Annex C to this Joint Proxy Statement/Prospectus.
 
     In the past, Hambrecht & Quist has provided investment banking and other
financial advisory services to IDB and has received customary fees for rendering
these services. Hambrecht & Quist acted as a managing underwriter of public
offerings of IDB's Common Stock in November 1991, May 1993 and November 1993 and
of IDB Notes in August 1993. Hambrecht Quist has provided research coverage for
IDB and from time to time recommended the purchase of IDB securities. In the
ordinary course of business, Hambrecht & Quist acts as a market maker and broker
in the publicly traded securities of IDB and receives customary compensation in
connection therewith. In the ordinary course of business, Hambrecht & Quist
actively trades in the publicly traded securities of IDB for its own account and
for the accounts of its customers and, accordingly, may at any time hold a long
or short position in such securities. In addition, Hambrecht & Quist is a
defendant in certain of the consolidated actions pending in the United States
District Court for the Central District of California under the caption In re
IDB Communications Group, Inc. Securities Litigation, Master File No.
CV-94-3618-RG (JGx). See "Information Regarding IDB -- Recent
Developments -- Stockholder Litigation and Other Proceedings."
 
     Hambrecht & Quist is an internationally recognized investment banking firm
and is regularly engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, corporate restructurings, strategic
alliances, negotiated underwritings, secondary distributions of listed and
unlisted
 
                                       46
<PAGE>   57
 
securities, private placements and valuations for corporate and other purposes.
The Board of Directors of IDB selected Hambrecht & Quist to act as its financial
advisor in connection with the Merger on the basis of its knowledge of IDB
through prior engagements and such experience.
 
     Pursuant to the terms of an engagement letter dated July 11, 1994, IDB has
agreed to pay to Hambrecht & Quist an advisory fee of $100,000 and an additional
fee of $500,000 at such time as Hambrecht & Quist was requested to provide an
opinion on fairness from a financial point of view of the consideration to be
received by IDB's stockholders in connection with sale of IDB. Upon delivery of
any subsequent fairness opinion (if requested by IDB) involving the same
potential acquiror for which a fairness opinion has previously been rendered,
IDB will pay Hambrecht & Quist $250,000. IDB agreed to pay a transaction fee of
approximately $5.4 million (assuming a per share price of LDDS Common Stock of
$22.50) based on the aggregate consideration received by IDB's stockholders in
the Merger net of the $850,000 previously described prior payments for acting as
IDB's financial advisor in connection with the Merger, including the rendering
of Hambrecht & Quist's opinion(s). Except as set forth above, such transaction
fee is payable upon consummation of the Merger. In the event that IDB becomes a
party to a transaction that does not constitute a sale of IDB, IDB has agreed to
pay Hambrecht & Quist a fee consistent with market practice. IDB also has agreed
to reimburse Hambrecht & Quist for its reasonable out-of-pocket expenses,
including fees and expenses of counsel, and to indemnify Hambrecht & Quist
against certain liabilities, including liabilities under the federal securities
laws or relating to or arising out of Hambrecht & Quist's engagement as
financial advisor.
 
  Chemical Securities Inc.
 
     In addition to retaining Hambrecht & Quist, IDB's Board of Directors
retained Chemical as IDB's financial advisor in connection with the possible
business combination involving LDDS. Chemical is continually engaged in the
valuation of businesses and their securities in connection with mergers and
acquisitions and valuations for estate, corporate and other purposes. IDB's
Board of Directors selected Chemical to act as IDB's financial advisor based on
Chemical's experience in mergers and acquisitions and in securities valuations
generally.
 
     On July 28, 1994, Chemical orally advised IDB's Board of Directors that, on
and as of such date, and based on various considerations and assumptions and
subject to its final review of the Merger Agreement, the Exchange Ratio was
fair, from a financial point of view, to the holders of IDB Common Stock.
Chemical confirmed its oral advice by delivery of its written opinion, dated
August 1, 1994. At the request of IDB's Board of Directors, on September 19,
1994 and in light of the proposed WilTel Acquisition and the financing thereof,
Chemical reconfirmed its opinion and orally advised IDB's Board of Directors
that, on and as of such date, and based on various considerations and
assumptions, the Exchange Ratio was fair, from a financial point of view, to the
holders of IDB Common Stock, whether or not the WilTel Acquisition was
consummated. Chemical confirmed its oral advice by delivery of its confirmatory
written opinion, dated September 19, 1994. THE FULL TEXT OF CHEMICAL'S
CONFIRMATORY WRITTEN OPINION, WHICH SETS FORTH THE ASSUMPTIONS MADE, PROCEDURES
FOLLOWED, MATTERS CONSIDERED AND LIMITS OF ITS REVIEW, IS ATTACHED HERETO AS
APPENDIX D AND IS INCORPORATED BY REFERENCE HEREIN. HOLDERS OF IDB COMMON STOCK
ARE URGED TO AND SHOULD READ CHEMICAL'S CONFIRMATORY WRITTEN OPINION IN ITS
ENTIRETY.
 
     In connection with Chemical's confirmatory written opinion, Chemical
reviewed and analyzed, among other things: (a) the Merger Agreement, the WilTel
Acquisition agreement and the terms of the financing related to the WilTel
Acquisition and the Schedule 14A, including the Preliminary Joint Proxy
Statement, relating to the Merger as filed with the Securities and Exchange
Commission on September 12, 1994, (b) certain publicly available financial
information of IDB, LDDS and Williams, including the Annual Report on Form 10-K
of each of IDB, LDDS and Williams for the fiscal year ended December 31, 1993
and the Quarterly Report on Form 10-Q of each of IDB, LDDS and Williams for the
quarter ended June 30, 1994, (c) the terms of the Certificate of Incorporation
and Bylaws of IDB and LDDS as in effect prior to the effective time of the
Merger and such other documents defining the rights of securityholders of IDB
and LDDS, (d) certain internal financial and operating data of IDB and LDDS
(with and without WilTel), including management forecasts, which took into
account for calendar years 1994 and 1995 IDB's financial projections as revised
based on IDB management's determination to revise certain accounting principles
and
 
                                       47
<PAGE>   58
 
update its financial forecasts, and (e) certain pro forma combined information
giving effect to the Merger, with and without the WilTel Acquisition, prepared
jointly by the managements of IDB and LDDS concerning potential cost savings and
efficiencies expected to result from the Merger, with and without the WilTel
Acquisition. Chemical also engaged in discussions with members of the senior
management of IDB, LDDS and WilTel regarding the past and current business
operations, financial condition and future prospects of their respective
companies. In addition, Chemical has reviewed the reported price and trading
activity for IDB Common Stock and LDDS Common Stock, compared certain financial
and stock market information for certain other companies, the securities of
which are publicly traded, reviewed the financial terms of recent business
combinations in the telecommunications services industry and in other industries
generally, and performed such other studies and analyses as Chemical considered
appropriate.
 
     Chemical relied without independent verification upon the accuracy and
completeness of all the financial and other information reviewed by it for
purposes of its opinion. In addition, Chemical did not make an independent
evaluation or appraisal of the assets and liabilities of IDB and LDDS (with or
without WilTel) or any of their respective subsidiaries and was not furnished
with any such evaluation or appraisal. In connection with the exchange ratio
negotiations, IDB provided certain financial information, including projections,
to representatives of Chemical. The projections consisted of income statement
projections and certain supporting assumptions by business unit for fiscal years
1994 and 1995 presented on a quarterly basis. The assumptions included
information regarding the number of inbound and outbound minutes and the
associated rates. The original projections were subsequently updated in July
principally to reflect the impact of the change to IDB's method of accounting
for international long distance traffic. These projections were among the
materials considered by Chemical in reaching its opinion. With respect to
information related to the prospects for IDB and LDDS (with and without WilTel),
Chemical assumed that such information reflected the best currently available
judgment and estimates of the managements of IDB, LDDS and WilTel as to the
future financial performance of IDB or LDDS (with and without WilTel), as the
case may be, and as to the estimated cost savings and synergies expected to
result from the combination of IDB and LDDS (with and without WilTel). Chemical
was not requested to, and did not, participate in the negotiations relating to
the Merger or the WilTel Acquisition or solicit third party indications of
interest in acquiring any or all of IDB's assets, properties or securities.
 
     Chemical has assumed with the consent of IDB's Board of Directors that in
the course of obtaining the necessary consents and approvals, or any amendments,
modifications or waivers to any documents to which either IDB, LDDS or WilTel
are a party, as contemplated by the Merger Agreement or the WilTel Agreement, no
restrictions will be imposed or amendments, modifications or waivers made that
would have any adverse effect on the contemplated benefits to the holders of IDB
Common Stock following the Merger. In addition, Chemical assumed with the
consent of IDB's Board of Directors that the Merger will be recorded as a
pooling-of-interests under generally accepted accounting principles and will be
tax-free to IDB, LDDS and their respective shareholders. Chemical based each of
its opinions on market, economic and other conditions existing on the date of
the opinion and on the information made available to it as of the date of the
opinion. In rendering its written confirmatory opinion, Chemical did not take
into account any future agreement which LDDS might enter into to effect a
material acquisition transaction subsequent to the date of such opinion other
than the WilTel Acquisition agreement.
 
     The following is a summary of financial analyses utilized by Chemical and
reviewed with IDB's Board of Directors at the meeting of the Board of Directors
on September 19, 1994, and does not purport to be a complete description of the
analyses performed by Chemical. The preparation of a fairness opinion is a
complex process and is not necessarily susceptible to partial analysis or
summary description. Selecting portions of the analyses or of the summary set
forth below, without considering the analysis as a whole, could create an
incomplete view of the processes underlying Chemical's opinion. In arriving at
its fairness determination, Chemical considered the results of all such
analyses. The analyses were prepared solely for the purposes of enabling
Chemical to render its opinion to IDB's Board of Directors as to the fairness of
the Exchange Ratio, and do not purport to be appraisals or necessarily reflect
the prices at which IDB or its securities actually may be sold. Analyses based
upon forecasts of future results are not necessarily indicative of actual future
values, which may be significantly more or less favorable than suggested by such
analyses.
 
                                       48

     Contribution Analysis.  Chemical reviewed certain historical and estimated
future operating and financial information (including, among other things,
revenue, earnings before interest, taxes, depreciation and amortization
("EBITDA"), earnings before interest and taxes ("EBIT"), net income and book
value) for IDB and LDDS (with and without WilTel) based on actual results, IDB,
LDDS and WilTel managements' financial forecasts for each of their respective
companies, and, in the case of the pro forma consolidated LDDS/WilTel forecasts,
certain assumptions prepared jointly by the managements of LDDS and WilTel
pertaining to potential cost savings and efficiencies expected to result from
the combination of LDDS and WilTel. Based on such review, Chemical analyzed the
relative financial contributions of each of IDB and LDDS (with and without
WilTel) to the pro forma consolidated organization for the twelve month period
ending June 30, 1994 and for the forecasted twelve month period ending December
31, 1995. Based on such analysis, Chemical determined that IDB's contributions
to the pro forma consolidated organization (without WilTel) of revenue, EBITDA,
EBIT, net income and book value for the twelve month period ended June 30, 1994
were 21.7%, 11.4%, 8.5%, 7.5% and 15.3%, respectively, and for the twelve month
forecasted period ending December 31, 1995 were 29.1%, 15.0%, 16.0%, 17.2%, and
20.3%, respectively. Alternatively, Chemical determined that IDB's contributions
to the pro forma consolidated organization (with WilTel) of revenue, EBITDA,
EBIT, net income and book value for the twelve month period ended June 30, 1994
were 15.5%, 7.8%, 6.3%, 6.4% and 14.0%, respectively, and for the twelve month
forecasted period ending December 31, 1995 were 20.9%, 9.8%, 11.6%, 17.0%, and
20.1%, respectively. The results of such analyses were then compared to the pro
forma ownership percentage of holders of IDB Common Stock in the pro forma
consolidated organization (with WilTel) of between 20.2% and 22.6%, based on a
range of exchange ratios of approximately 0.451 and 0.520 of a share of LDDS
Common Stock for each share of IDB Common Stock and considering certain
adjustments relating to the exercise, as a result of the Merger, of certain LDDS
options. Except in the case of the relative contributions of revenue, the
Contribution Analysis indicated that the Exchange Ratio was favorable to IDB's
shareholders.
 
     Pro Forma Merger Analysis.  Chemical reviewed certain financial
information, including the financial projections of IDB on a stand-alone basis
for the fiscal year ending December 31, 1995 and the pro forma financial
projections for the consolidated organization (with and without WilTel)
resulting from the Merger for the fiscal year ending December 31, 1995. The pro
forma financial projections for the consolidated organization resulting from the
Merger were based on the respective financial projections of the managements of
IDB, LDDS and WilTel and certain assumptions prepared jointly by the managements
of IDB and LDDS pertaining to potential cost savings and efficiencies expected
to result from the Merger ("IDB/LDDS cost savings") and certain assumptions
prepared jointly by the managements of LDDS and WilTel pertaining to potential
cost savings and efficiencies expected to result from LDDS' acquisition of
WilTel ("LDDS/WilTel cost savings"). Based on the above, Chemical calculated the
implied earnings per share ("EPS") for the consolidated organization (with and
without WilTel) for the fiscal year ending December 31, 1995. Such analysis
indicated that the Merger would be accretive to EPS (as adjusted by the Exchange
Ratio range to determine the equivalent EPS range per share of IDB Common Stock)
within implied ranges of approximately 17.4% to 31.4% (without WilTel and
excluding IDB/LDDS cost savings) and approximately 29.5% to 44.9% (with WilTel
and including LDDS/WilTel cost savings), in each case considering certain
adjustments relating to the exercise, as a result of the Merger, of certain LDDS
options, for IDB stockholders, who pursuant to the Merger would become holders
of shares of the consolidated organization, in comparison with EPS of IDB on a
stand-alone basis. While Chemical noted that without LDDS/WilTel cost savings
the Merger would potentially be dilutive to IDB shareholders, it also noted that
management believed that cost savings and efficiencies would be inherent in the
combination of LDDS' and WilTel's operations. The Pro Forma Merger Analysis
indicated that the Merger, except as noted above, would be accretive to IDB
shareholders.
 
     Comparable Company Analysis.  Chemical reviewed and compared certain actual
and estimated financial, operating and stock market information of IDB, LDDS and
selected companies in the telecommunications services industry, including ACC,
ALC, LCI, MFS Communications Company, RCI Corporation, and U.S. Long Distance
Corporation (collectively, the "Selected Comparable Companies"), and AT&T, MCI,
and Sprint (together with the Selected Comparable Companies, the "Comparable
Companies"). Chemical compared market values as multiples of historical net
income and projected EPS of the Selected
 
                                       49
<PAGE>   60
 
Comparable Companies and the Comparable Companies. Chemical also compared the
adjusted market values (equity market value, plus the book value of debt and
preferred stock, less cash and cash equivalents) as multiples of historical
revenue, EBITDA and EBIT of the Selected Comparable Companies and the Comparable
Companies. The following table summarizes certain market multiples derived from
Chemical's analysis as of September 15, 1994:

     Projected EPS multiples for the Comparable Companies were based on the
consensus EPS estimates of selected investment banking firms. All multiples were
based on closing stock prices as of September 15, 1994. The Comparable Company
Analysis, particularly in the case of multiples of adjusted market value,
indicated that relative to LDDS and to the Comparable Companies, IDB's current
stock price was not undervalued, and relative to the IDB and the Comparable
Companies, the current stock price of LDDS was not overvalued.
 
     Comparable Transaction Analysis.  Chemical reviewed publicly available
information relating to selected public and private market transactions in the
telecommunications services industry and certain significant stock-for-stock
mergers. Such transactions include: the merger of LDDS, MCC and Resurgens; the
merger of LDDS and ATC; the pending 20% acquisition by Deutsch Telekom and
France Telecom of Sprint; the 20% acquisition by British Telecom PLC of MCI; the
merger of Sprint and Centel Corporation; and the merger of GTE Corporation and
Contel Corporation (the "Selected Transactions"). Assuming a value of LDDS
Common Stock of $22.875 (the closing price of LDDS Common Stock as of September
15, 1994) and an implied exchange ratio of approximately 0.451 of a share of
LDDS Common Stock for each share of IDB Common Stock in the Merger, such
analysis indicated that for the Selected Transactions (i) levered aggregate
consideration as mean and median multiples of sales, EBITDA and EBIT for the
twelve months ended June 30, 1994 were 2.7 and 2.6, 11.0 and 11.5 and 19.2 and
18.7, respectively, as compared to corresponding values of 2.3, 19.8 and 39.3,
respectively, in the Merger, (ii) aggregate consideration as mean and median
multiples of net income for the twelve months ended June 30, 1994, forecasted
fiscal year 1994 EPS and forecasted fiscal year 1995 EPS were 36.7 and 36.4,
24.8 and 23.1 and 20.5 and 21.5, respectively, as compared to corresponding
values of 73.3, 23.5 and 16.9, respectively, in the Merger and (iii) the mean
and median percentage premium to market capitalization on the date prior to
public announcement and for the thirty day period prior to public announcement
were 16.9% and 16.0% and 21.9% and 20.1%, respectively, as compared to
corresponding values of 11.5% and 11.9% (or, assuming a value of LDDS Common
Stock of $19.00 (the closing price as of July 25, 1994), values of -11.1% and
- -0.9%), respectively, in the Merger. The Comparable Transaction Analysis
indicated that implied multiples of the Merger based on last twelve month
financial results generally compared favorably with multiples based on the
Selected Transactions, and implied multiples of the Merger based on forecasted
financial results generally were on the low side of multiples based on Selected
Transactions. Chemical also noted that the implied stock premium of the Merger
was on the low side of premiums paid in Selected Transactions.
 
     Other Analyses.  Chemical reviewed and analyzed the historical trading
prices and volumes for IDB Common Stock and LDDS Common Stock, separately and in
comparison to one another and to indices of the Comparable Companies.

     The terms of the engagement of Chemical by IDB are set forth in the letter
agreement dated July 12, 1994 between Chemical and IDB (the "Engagement
Letter"). Pursuant to the terms of the Engagement Letter, IDB has paid to
Chemical a fee of $100,000 upon execution of the Engagement Letter and a fee of
$500,000 upon delivery of its written opinion dated August 1, 1994. Additional
opinion fees of $250,000 are due upon delivery of any subsequent fairness
opinions, if requested by IDB, including in respect of Chemical's confirmatory
written opinion dated September 19, 1994. In addition, IDB has agreed to pay
Chemical a transaction fee (against which IDB is entitled to credit all fees
previously paid to Chemical) payable upon consummation of the Merger of 0.1875%
of the aggregate consideration paid in the Merger, provided that the fee for
amounts payable to the holders of IDB Common Stock in excess of an implied value
of $12.00 per share shall be equal to 1.00% of such excess consideration. For
purposes of calculating the transaction fee, the value of the LDDS Common Stock
to be received by holders of IDB Common Stock pursuant to the Merger Agreement
will be the last sale price for LDDS Common Stock on the day prior to closing.
In addition, IDB has agreed to reimburse Chemical for its reasonable
out-of-pocket expenses, including fees and disbursements of its counsel, and to
indemnify Chemical against certain liabilities relating to or arising out is its
engagement.
 
     Chemical Bank and its affiliates, including Chemical Securities Inc., in
the ordinary course of business, have, from time to time, provided, and in the
future may continue to provide, personal banking services, including the making
of loans and money management services, to certain officers and directors of IDB
and LDDS, as well as providing general commercial banking services to companies
in which they have a financial interest or for which they serve as an officer,
director or employee. Chemical Bank has agreed in the amount of $85,000,000 to
participate as a member of the syndicate of banks which may provide financing of
up to $3,410,000,000 to LDDS in connection with the WilTel acquisition. Chemical
Bank and its affiliates, including Chemical Securities Inc., have provided, and
in the future may provide, commercial and investment banking services to
Williams. In the ordinary course of business, Chemical Bank or its affiliates
may trade in the debt and equity securities of IDB, LDDS and Williams for
Chemical Bank's or its affiliates' own accounts and for the accounts of their
customers and, accordingly, may at any time hold a long or short position in
such securities.
 
MANAGEMENT AND OPERATIONS AFTER THE MERGER
 
     After the Merger, IDB is expected to continue to operate under its current
name as a subsidiary of LDDS. Following the Merger, it is anticipated that the
LDDS Board will consist of the current directors of LDDS and the IDB nominee
LDDS has agreed to elect or appoint to the LDDS Board pursuant to the terms of
the Merger Agreement. It is anticipated that Mr. Sudikoff will be the IDB
nominee appointed to serve as a director on the LDDS Board. See "-- Certain
Covenants" and "-- Interests of Certain Persons in the Merger -- Director
Nominee." For further information concerning LDDS directors, reference is made
to the 1994 LDDS Proxy Statement, which is incorporated in relevant part herein
by reference.
 
     If the WilTel Acquisition is consummated, WilTel is expected to operate as
a subsidiary of LDDS and continue to conduct business under the name of WilTel
Network Services under a limited license from Williams.

     ACCOUNTING CONTINGENCY.  Notwithstanding any other provisions of the Merger
Agreement, LDDS has acknowledged that it has reviewed all statements (the
"Relevant Statements") made by IDB concerning the "Accounting Contingency"
(defined below) in its filings with the Commission, and has agreed that, except
as to the Relevant Statements, it is not relying on any statement,
representation, warranty or other disclosure made by IDB or its representatives
regarding the Accounting Contingency. LDDS agrees that no representation,
warranty or covenant of IDB set forth in the Merger Agreement shall be deemed to
have been breached and no condition to the obligations of LDDS shall be deemed
to be unsatisfied as a result of the Accounting Contingency or the claims of any
persons (or the costs, expenses, liabilities or damages relating to such claims)
arising out of the Accounting Contingency, except and only to the extent that
such breach or unsatisfied condition is attributable to a misstatement or
omission with respect to a material fact in the Relevant Statements, the
reliability of which is not otherwise questioned by other disclosures in the
Relevant Statements.
 
     The term "Accounting Contingency" means generally any matters disclosed in
the filings of IDB with the Commission relating to accounting disagreements
between IDB and Deloitte, or the resignation on May 23, 1994 of Deloitte as
IDB's auditors, or accounting adjustments or restatements relating to the
financial statements of IDB for the fiscal quarter ended March 31, 1994, and all
litigation ongoing, pending, threatened or subsequently commenced to the extent
arising or resulting from any such matters or the consequences or results of any
such matters. See "Information Regarding IDB -- Recent Developments."
 
     CERTAIN COVENANTS.  IDB has agreed (i) to use reasonable business efforts
to cause Mr. Sudikoff to certify that he has no plan or intention to sell,
exchange or otherwise dispose of shares of LDDS Common Stock received in the
Merger, (ii) to cooperate to seek to obtain, at or prior to the Closing,
noncompete and confidentiality agreements on reasonable terms from key employees
of IDB (other than such employees who are already parties to similar agreements
with LDDS); (iii) to use reasonable business efforts to cause each person who is
an "affiliate" of IDB within the meaning of the Securities Act to execute a
letter agreement restricting the sale of LDDS Shares for certain purposes (see

regarding certain IDB Options granted to Jeffrey P. Sudikoff, Edward R. Cheramy
and Rudy Wann, such rescission to be effective at the Effective Time.
 
     LDDS has agreed to cause Mr. Sudikoff or, if he is unable or declines to
serve, such other person as may be designated prior to the Effective Time by
IDB, to be elected or appointed to the Board of Directors of LDDS promptly after
the Effective Time, provided Mr. Sudikoff or such other person, as the case may
be, consents thereto and, in the reasonable judgment of the Board of Directors
of LDDS, is qualified to serve. See "-- Interests of Certain Persons in the
Merger -- Director Nominee" and "-- Effect on Employment Agreements" for further
information regarding Mr. Sudikoff and see "Information Regarding IDB -- Recent
Developments" for a discussion of certain legal proceedings involving Mr.
Sudikoff.
 
     After the Effective Time, LDDS has agreed to arrange for each participant
in any of the employee benefit plans of IDB to participate in any counterpart
plans of LDDS in accordance with the eligibility criteria thereof. In connection
therewith, LDDS has agreed that (i) such participants shall receive full credit
for years of service with IDB prior to the Merger for all purposes for which
such service was recognized under the IDB plan, (ii) such participants shall
participate in LDDS plans on terms no less favorable than those offered by LDDS
to similarly situated employees, (iii) any provisions in such LDDS benefit plans
which restrict benefits by reason of pre-existing conditions shall be waived to
the extent the insurer thereunder will permit such waiver without an increase in
premiums or other cost to LDDS, and (iv) each IDB employee shall receive credit
under LDDS plans for co-payments and payments under a deductible limit made
during the current
 
                                       53
<PAGE>   64
 
year in accordance with the corresponding IDB benefit plan to the extent the
insurer will permit such credit without an increase in premiums or other cost to
LDDS.
 
     LDDS has also agreed to indemnify and hold harmless directors, executive
officers, employees and agents of IDB as described under "-- Interests of
Certain Persons in the Merger -- Indemnification."
 
     IDB and LDDS have agreed to give the other party prompt notice of the
following: (i) any notice of a default or event which, with notice or the
passage of time, would become a default under any material contract which could
have a material adverse effect on that party, (ii) receipt of any notice from a
third party alleging that its consent is required in connection with the Merger,
(iii) receipt of any material notice from any regulatory body in connection with
the Merger, (iv) the occurrence of an event which would have a material adverse

Merger Agreement, would have been required to be disclosed, and (vi) the
occurrence of any event that would cause a breach by such party of the Merger
Agreement or that, if such event had occurred on the date of the Merger
Agreement, would have been required to have been disclosed.
 
     IDB and LDDS have agreed to give the other reasonable access to its plants
and facilities and, subject to applicable law and compliance with contractual
obligations, all contracts, agreements and books and records, to permit
reasonable inspections, and to furnish the other party with such financial and
operating data as may be reasonably requested.
 
     IDB and LDDS have each agreed to give notice of and hold a meeting of its
shareholders for the purpose of obtaining any necessary adoption and approval of
certain matters relating to the Merger and, subject to directors' fiduciary
obligations under applicable law as advised by counsel, the Board of Directors
of each party will recommend to shareholders that they provide such approval.
 
     Subject to directors' fiduciary obligations under applicable law as advised
by counsel, IDB and LDDS have each agreed to use reasonable business efforts to
take or cause to be taken all things necessary or advisable to consummate and
make effective the Merger, including, without limitation, (i) obtaining the
consent to the Merger of its lenders and others, (ii) defending any litigation
against such party challenging the Merger Agreement, (iii) obtaining consents
from governmental authorities required for the Merger, and (iv) timely making
filings under the Hart-Scott-Rodino Act.

Merger Agreement); (iii) split, combine or reclassify any shares of its capital

or by IDB as described in clause (iv) of the immediately preceding paragraph,
IDB will be required to pay to LDDS in cash the sum of $8 million; provided,
that no such payment is required in the event of termination under circumstances
described in clause (iv)(b) of the immediately preceding paragraph unless and
until IDB, within a period of six months after such termination, enters into an
agreement in principle, letter of intent or definitive agreement respecting an
Alternative Transaction. Further, if the Merger Agreement is terminated by IDB

pay to IDB in cash the sum of $8 million.
 
     The Merger Agreement, including the provision setting forth an outside date
for consummation of the Merger of March 31, 1995 and all other material terms
thereof, may be amended or modified in writing by the parties thereto by action
of their respective Boards of Directors, to the extent permitted by applicable
law, at any time before the Effective Time.
 
     AGREEMENT NOT TO SOLICIT OTHER OFFERS.  Pursuant to the Merger Agreement,
subject to continued compliance with the fiduciary duties of IDB's directors
under applicable law as advised by counsel to IDB, IDB has agreed not to, nor to
direct its officers, directors and other representatives to, directly or
indirectly, initiate, solicit or encourage discussions or negotiations with, or
provide any information or assistance to, any third party concerning any
acquisition of shares of capital stock or assets of IDB or any of its
subsidiaries (whether by merger, consolidation, purchase of assets, tender offer
or otherwise). IDB has agreed to promptly notify LDDS if any proposal with
respect to the foregoing is made.
 
     CLOSING DATE.  The closing of the Merger will occur on a mutually agreeable
date (the "Closing Date") as soon as practicable after the satisfaction or
waiver of all conditions to the Merger. The Closing Date will be the date on
which the Effective Time occurs.
 
     EXPENSES.  All fees, costs and expenses required or incurred in connection
with the Merger Agreement will be paid by the party incurring such costs or
expenses, subject to the provisions described in "-- Termination and Amendment
of the Merger Agreement."

INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     In considering the recommendation of IDB's Board of Directors with respect
to the Merger Agreement, IDB stockholders should be aware that certain members
of IDB's management and its Board of Directors have interests in the Merger that
are in addition to their interests as IDB stockholders. Each of the members of
IDB's Board of Directors was aware of those interests in effect on the date of
approval and considered them, among other matters, in approving the Merger
Agreement and the transactions contemplated thereby.
 
     EFFECT ON EMPLOYMENT AGREEMENTS.  Messrs. Sudikoff, Cheramy and Hartz are
parties to employment agreements with IDB dated as of January 1, 1992, each with
a five year term which is automatically extended by an additional year after the
expiration of each year, subject to earlier termination under certain
circumstances. In the event of a "change of control" of IDB (as defined in such
employment agreements), amounts payable through the remaining term of the
employment agreements become immediately payable, with IDB obligated to pay any
taxes that are specifically levied on payments made pursuant to change of
control provisions. The consummation of the Merger would result in a "change in
control" under the employment agreements.
 
     The Merger Agreement provides as a condition to LDDS's obligation to
consummate the Merger that IDB shall have terminated or arranged for the
termination of the employment agreements with Messrs. Sudikoff, Cheramy and
Hartz. The Merger Agreement permits IDB to compromise or settle its obligations
under the employment agreements by payment of not more than $13 million in the
aggregate to these three executive officers. IDB has arranged for the
termination of the employment agreements with Messrs. Sudikoff, Cheramy and
Hartz and has agreed to pay $6,350,193, $5,283,185 and $1,366,622, respectively,
to settle its obligations thereunder. In the event that any of Messrs. Sudikoff,
Cheramy or Hartz is terminated "for cause," as defined in their respective
employment agreements, IDB would have no severance obligations to such officer.
 
     If the Merger is consummated, Messrs. Sudikoff and Carroll and certain
other executive officers are anticipated to be employed by the Surviving
Corporation or one of its subsidiaries. Mr. Sudikoff is anticipated to be
employed as the Chief Executive Officer of WorldCom International, Inc.
("WorldCom"), a subsidiary of IDB. Although no definitive agreement has been
reached between LDDS and Mr. Sudikoff regarding his employment after the Merger,
the parties discussed the material terms of such an employment arrangement
during the negotiation of the Merger. The proposed terms, as summarized below,
were also presented to the Boards of Directors of both companies and considered
by them in approving the Merger. Neither party has any legal obligation to enter
into any employment agreement; accordingly, there can be no assurance that the
parties will enter into any such agreement or that the terms of any such
agreement will be as described below.
 
     The terms of Mr. Sudikoff's proposed employment agreement include an annual
base salary of $450,000. In addition, Mr. Sudikoff would be eligible to
participate with other eligible employees of WorldCom in an annual bonus pool
not to exceed $1.0 million. Receipt of any bonus would be contingent upon
achievement of business plan objectives and goals to be determined annually and
approved by LDDS. In addition, it is contemplated that options to purchase
100,000 shares of LDDS Common Stock may be granted to Mr. Sudikoff each year for
a period of five years based on Mr. Sudikoff's performance with WorldCom. Mr.
Sudikoff may receive other performance incentives, retirement and health
benefits and other fringe benefits comparable to the benefits provided by LDDS
to its executive officers.
 
     The proposed employment agreement would have a five year term but would be
terminable at the option of either LDDS or Mr. Sudikoff at any time. If Mr.
Sudikoff were terminated during the term of his employment agreement without
cause, he would only be entitled to receive payments in an amount equal to his
base salary and bonus for the balance of the calendar year in which he is
terminated.
 
     The Merger Agreement permits IDB, in its discretion, to grant bonuses to
certain of its key employees in order to encourage those employees to continue
in their employment until the Closing Date. IDB anticipates granting bonuses for
not more than $255,000 in the aggregate, none of which bonuses will exceed
$50,000 to any individual.

     ACQUISITION OF SCI.  Messrs. Sudikoff, Cheramy and Hartz own 49%, 40% and
11%, respectively, of the capital stock of SCI. In order to allow foreign
ownership of IDB to exceed 25% without risk of refusal or revocation of licenses
pursuant to the Communications Act, on December 17, 1992, subsidiaries of IDB
that had held the transmission licenses used by IDB assigned all of their common
carrier earth station and microwave licenses to SCI in exchange for SCI's
entering into certain operating agreements with IDB and the licensed
subsidiaries. No monetary compensation has been received by IDB or its
subsidiaries in connection with such assignments. These operating agreements
have initial terms of ten years and provide for SCI to be the operator and FCC
licensee of the satellite earth stations and microwave stations owned by IDB. In
accordance with these agreements, IDB paid $34,200 to SCI during 1993 as an
operator fee. The operator fees are subject to adjustment annually. Consistent
with the terms of the Merger Agreement, the assets of SCI will be sold to a
subsidiary of LDDS for a nominal consideration. See "Plan of Merger -- Terms and
Conditions of the Proposed Merger."
 
     IDB OPTIONS.  As of November 1, 1994, executive officers and directors of
IDB held options to purchase an aggregate of 2,953,444 shares of IDB Common
Stock at various exercise prices and subject to various vesting schedules. The
outstanding IDB Options were granted under the 1992 Incentive Stock Plan, the
1992 Stock Option Plan for Nonemployee Directors and the 1986 Incentive Stock
Plan, or under individual option agreements. All IDB Options outstanding
immediately prior to the Effective Time will be converted into options to
acquire LDDS Common Stock having the same terms and conditions as the IDB
Options except that the exercise price and the number of shares issuable upon
exercise will be divided and multiplied, respectively, by the Exchange Ratio. As
indicated in the following table, certain of these IDB Options held by certain
directors and executive officers will automatically vest upon the Effective Time
pursuant to change in control provisions in their respective employment
agreements:

     DIRECTOR NOMINEE.  The Merger Agreement provides that, promptly after the
Effective Time, LDDS will cause Mr. Sudikoff or, if Mr. Sudikoff is unable or
declines to serve, such other person as may be designated prior to the Effective
Time by the Board of Directors of IDB, to be elected or appointed to the Board
of Directors of LDDS, provided Mr. Sudikoff or such other person, as the case
may be, consents thereto and, in the reasonable judgment of the Board of
Directors of LDDS, is qualified to serve. Mr. Sudikoff, age 39, has been the
Chief Executive Officer and a director of IDB since its incorporation in
September 1983 and has been Chairman of the Board of Directors since May 1986.
He also served as IDB's President from September 1983 until March 1989. From
1978 until founding IDB, Mr. Sudikoff provided consulting services to the radio
broadcast industry in the areas of programming production and distribution. As
of the IDB Record Date, Mr. Sudikoff did not beneficially own any LDDS equity
securities. Based on his beneficial ownership of IDB Common Stock as of the IDB
Record Date, Mr. Sudikoff will beneficially own from 2,141,018 to 2,470,404
shares of LDDS Common Stock, or from      % to      % of the outstanding shares
of LDDS Common Stock, after the Merger. See "-- Employment Agreements with LDDS"
for a description of Mr. Sudikoff's employment arrangements with LDDS and see
"Information Regarding IDB -- Recent Developments" for a discussion of certain
legal proceedings involving Mr. Sudikoff. See "Information Concerning Board of
Directors" contained in the 1994 LDDS Proxy Statement incorporated herein by
reference for a discussion of the compensation of directors of LDDS. See
"Available Information" and "Incorporation by Reference."
 
     INDEMNIFICATION.  The Merger Agreement provides that, from and after the
Effective Time, LDDS and the Surviving Corporation, jointly and severally,
shall, to the full extent provided in IDB's Restated Certificate of
Incorporation, Bylaws and applicable indemnification agreements, as in effect on
August 1, 1994, indemnify, defend, advance the costs of defense of and hold
harmless each present and former director, officer, employee and agent of IDB
against any costs or expenses (including attorneys' fees), judgments, fines and
 
                                       58
<PAGE>   69
 
amounts paid in settlement in connection with any claim, action, suit,
proceeding or investigation, whether civil, criminal, administrative or
investigative, relating to any action or omission occurring at or prior to the
Effective Time, including, without limitation, those arising out of transactions
contemplated by the Merger Agreement and those arising out of the Accounting
Contingency. See "Risk Factors -- Factors Concerning IDB," and "Information
Regarding IDB -- Recent Developments" for a discussion of certain legal
proceedings involving directors and executive officers of IDB.
 
     CERTAIN EMPLOYEE BENEFIT MATTERS.  The Merger Agreement provides that,
after the Effective Time, LDDS has agreed to arrange for each participant in any
of the employee benefit plans of IDB to participate in any counterpart plans of
LDDS in accordance with the eligibility criteria thereof. In connection
therewith, LDDS has agreed that (i) such participants shall receive full credit
for years of service with IDB prior to the Merger for all purposes for which
such service was recognized under the IDB plan, (ii) such participants shall
participate in LDDS plans on terms no less favorable than those offered by LDDS
to similarly situated employees, (iii) any provisions in such LDDS benefit plans
which restrict benefits by reason of pre-existing conditions shall be waived to
the extent the insurer thereunder will permit such waiver without an increase in
premiums or other cost to LDDS, and (iv) each IDB employee shall receive credit
under LDDS plans for co-payments and payments under a deductible limit made
during the current year in accordance with the corresponding IDB benefit plan to
the extent the insurer will permit such credit without an increase in premiums
or other cost to LDDS.
 
SURRENDER OF STOCK CERTIFICATES AND RECEIPT OF MERGER CONSIDERATION
 
     At the Effective Time, each holder of IDB Common Stock will be entitled to
receive the number of whole shares of LDDS Common Stock equivalent to the number
of shares of IDB Common Stock owned immediately prior to the Effective Time
multiplied by the Exchange Ratio, plus cash in lieu of fractional shares. The
Exchange Ratio will be based upon the Share Value. See "Summary
Information -- The Proposed Merger." If the Share Value is equal to or less than
$16.00, the Exchange Ratio will be 0.520231. If the Share Value is equal to or
greater than $22.00, the Exchange Ratio will be 0.450867. If the Share Value is
greater than $16.00 but less than $22.00, the Exchange Ratio increases or
decreases by 0.001445 of an LDDS Share for each $0.125 decrease or increase,
respectively, in the Share Value, as more fully set forth in Section 1.3 of the
Merger Agreement (provided that if the Share Value falls between any two of the
Share Values listed therein, the Exchange Ratio shall be that applicable to the
lower of the two Share Values). See "-- General Description of the Merger."
 
     As soon as practicable after the Effective Time, the Exchange Agent will
mail to each holder of IDB Common Stock notification of the consummation of the
Merger and instructions as to the procedure for the surrender of the stock
certificates. The Exchange Agent will accept documentation acceptable to it in
lieu of lost or destroyed certificates and may also require the holder of a lost
or destroyed certificate to post an insurance bond acceptable to the Exchange
Agent. Each holder of IDB Common Stock, upon surrender of a stock certificate or
certificates representing such stock, together with the transmittal letter
provided by the Exchange Agent duly completed and executed by such holder, will
be entitled to receive a stock certificate or certificates representing the
number of the whole shares of LDDS Common Stock (together with cash in lieu of
fractional shares) to which such holder is entitled.
 
     IDB STOCKHOLDERS SHOULD NOT SEND IN THEIR CERTIFICATES UNTIL THEY RECEIVE A
TRANSMITTAL LETTER FROM THE EXCHANGE AGENT.
 
     From and after the Effective Time, there shall be no further transfers on
the stock transfer books of IDB of any IDB Common Stock.
 
     No dividends or other distributions will be paid to a former stockholder of
IDB with respect to shares of LDDS Common Stock until such stockholder's stock
certificate(s) representing IDB Common Stock are remitted to the Exchange Agent.
Any dividends declared between the Effective Time and the date of the surrender
of the IDB stock certificate(s) will be held by the Exchange Agent for the
benefit of the holder and will be paid to the holder, without interest thereon,
upon the surrender of such stock certificate(s). Holders of any unsurrendered
certificates representing IDB Common Stock will not be entitled to vote the LDDS
 
                                       59
<PAGE>   70
 
Common Stock to which they are entitled until such certificates are exchanged
for certificates representing LDDS Common Stock.
 
FRACTIONAL SHARES
 
     No fractional shares of LDDS Common Stock will be issued in connection with
the Merger. Where the Merger consideration would otherwise require the issuance
of a fractional share, cash equal to such fractional interest multiplied by the
Share Value will be paid to the holder of such interest in lieu of a fractional
share.
 
CERTAIN REGULATORY FILINGS AND APPROVALS
 
     Consummation of the Merger is contingent upon the receipt of approvals from
the FCC with respect to the transfer of control of IDB to LDDS and certain
related transactions, including assignment of all of SCI's authorizations to a
wholly owned subsidiary of LDDS. See "Plan of Merger -- Terms and Conditions of
the Proposed Merger -- Mutual Conditions." All of the applications necessary to
obtain FCC approval for the consummation of the Merger were filed with the FCC
on August 19, 1994. The applications were placed on Public Notice on August 31,
1994. The deadline for the public to file comments or oppositions to the
applications expired on September 30, 1994. Comsat Corporation ("Comsat") filed
an opposition to certain portions of certain of the applications. No other party
filed an opposition or comments. LDDS, IDB and SCI responded to Comsat's
opposition on October 13, 1994. Comsat filed its reply on October 25, 1994. No
party is entitled to file any further pleadings, and the applications are now
ripe for consideration by the FCC. Consummation of the Merger is conditioned
upon FCC grant of the applications and such grant no longer being subject to
administrative or judicial reconsideration, review or appeal.
 
     Consummation of the Merger is also contingent upon notification to and/or
approval by various state PUCs. All of the notifications and/or requests for
approval of the transfer of control of IDB to LDDS have been filed with the
relevant PUCs.
 
     Under the Hart-Scott-Rodino Act and the rules promulgated thereunder by the
Federal Trade Commission (the "FTC"), the Merger may not be consummated until
notifications have been given and certain information has been furnished to the
FTC and the Antitrust Division of the Department of Justice (the "Antitrust
Division") and specified waiting period requirements have been satisfied. LDDS
and IDB filed notification and report forms under the Hart-Scott-Rodino Act with
the FTC and the Antitrust Division on September 2, 1994 and Mr. Sudikoff, who is
deemed an acquiror of LDDS by virtue of his IDB Common Stock ownership, filed a
notification and report form under the Hart-Scott-Rodino Act on September 8,
1994. The latest required waiting periods for such filings under the
Hart-Scott-Rodino Act expired on October 8, 1994. However, at any time before or
after the Effective Time of the Merger, and notwithstanding that the
Hart-Scott-Rodino Act waiting period has expired, the FTC, the Antitrust
Division or any state could take such action under the antitrust laws as it
deems necessary or desirable in the public interest. Such action could include
seeking to enjoin the consummation of the Merger or seeking divestiture of IDB
or businesses of LDDS or IDB acquired as a result of the Merger.
 
EFFECT OF MERGER ON IDB NOTES
 
     The IDB Notes are currently convertible at the holder's option at any time
into shares of IDB Common Stock. If the Merger is consummated, pursuant to the
Indenture under which IDB issued the IDB Notes, IDB will be required to enter
into a supplemental indenture, joined in by LDDS, under which IDB (as survivor
of the Merger) and LDDS expressly assume payment of the IDB Notes and
performance under the Indenture. In addition, the supplemental indenture must
provide that holders of the IDB Notes may, after the Effective Time of the
Merger, convert their IDB Notes into the number of LDDS Shares that they would
have received had they converted their IDB Notes immediately prior to the
Merger.
 
ACCOUNTING TREATMENT
 
     The Merger is designed to qualify as a "pooling of interests" for
accounting and financial reporting purposes. Under this method of accounting,
the recorded assets and liabilities of LDDS and IDB will be
 
                                       60
<PAGE>   71
 
carried forward to the combined organization at their recorded amounts; income
of the combined organization will include income of LDDS and IDB for the entire
fiscal year in which the Merger occurs; and the reported income of the separate
corporations for prior periods will be combined and restated as income of the
combined organization. Among the conditions to pooling of interests accounting
treatment of the Merger is the requirement that LDDS issue LDDS Common Stock in
exchange for at least 90% of the IDB Common Stock outstanding on the date the
Merger is consummated. The respective obligations of LDDS and IDB to consummate
the Merger are subject to the receipt by each of LDDS and IDB from Arthur
Andersen LLP, the independent auditors of each of LDDS and IDB, of its opinions
that the Merger will qualify as a pooling of interests.
 
     Certain stockholders of IDB and LDDS that may be "affiliates" (as defined
in the rules under the Securities Act) have agreed that they will not transfer
any shares of LDDS Common Stock received in the Merger until LDDS has published
financial statements containing at least 30 days of combined results of
operations after the Effective Date. Such restriction on transfer is necessary
to account for the Merger as a pooling of interests. See "-- Status Under
Federal Securities Laws."
 
PUBLIC TRADING MARKET
 
     LDDS and IDB anticipate that the shares of LDDS Common Stock to be issued
and reserved for issuance in connection with the Merger will be quoted on the
Nasdaq National Market.
 
STATUS UNDER FEDERAL SECURITIES LAWS
 
     The LDDS Shares to be issued to stockholders of IDB pursuant to the Merger
Agreement have been registered under the Securities Act, thereby allowing such
shares to be freely traded without restriction by persons who will not be
"affiliates" of LDDS after the Merger or who were not "affiliates" of IDB on the
date of the IDB Special Meeting. All directors and certain officers and
stockholders of IDB may be deemed to have been "affiliates" of IDB within the
meaning of such rules. Any such person may resell the LDDS Shares received by
him or her in the Merger only if such shares are registered under the Securities
Act or an exemption from registration under the Securities Act is available.
Such persons may be able to effect resales under the safe harbor provisions of
Rule 145 under the Securities Act (or Rule 144 in the case of such persons who
become "affiliates" of LDDS) or as otherwise permitted under the Securities Act.
Persons who may be deemed affiliates of IDB or LDDS generally include
individuals or entities that control, are controlled by, or are under common
control with, such party, and may include certain officers and directors of such
party as well as principal shareholders of such party. It is recommended that
any such person obtain advice of securities counsel prior to effecting any
resales.
 
     The Merger Agreement requires IDB to use reasonable business efforts to
cause each of its "affiliates" to execute a written agreement to the effect that
such person will not offer or sell or otherwise dispose of any of the LDDS
Shares received in the Merger (i) in violation of the Securities Act or the
rules and regulations thereunder and, (ii) in any event, until the time that
financial results covering at least 30 days of post-Merger combined operations
of IDB and LDDS have been published within the meaning of the accounting
policies of the Commission relating to pooling of interests.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     The following discusses only the federal income tax consequences of the
Merger to United States persons who hold IDB Shares as capital assets. It does
not discuss all the tax consequences that might be relevant to stockholders
entitled to special treatment under the federal income tax law or to
stockholders who acquired their IDB Shares or LDDS Shares through the exercise
or cancellation of employee stock options or otherwise as compensation.
 
     GENERAL.  IDB has received an opinion from O'Melveny & Myers to the effect
that, if the Merger is consummated in accordance with the terms of the Merger
Agreement and as described in this Joint Proxy Statement/Prospectus, for federal
income tax purposes, the Merger will constitute a reorganization within the
meaning of Section 368(a) of the Code. The opinion is based upon customary
representations made to
 
                                       61
<PAGE>   72
 
O'Melveny & Myers by IDB, LDDS and Mr. Sudikoff with respect to certain factual
matters required to qualify the Merger as a reorganization under the Code.
 
     As a reorganization, no gain or loss will be recognized by the stockholders
of IDB with respect to the LDDS Shares received in the Merger. The tax basis of
the LDDS Shares received by an IDB stockholder (including any fractional
interests) will be equal to the tax basis of the IDB Shares exchanged therefor.
For the purposes of determining whether a gain or loss on disposition of LDDS
Shares is long-term or short-term, the holding period of the LDDS Shares
received pursuant to the Merger by the IDB stockholders will include the holding
period of the IDB Shares exchanged therefor, provided the IDB Shares were held
as a capital asset on the date of the Merger.
 
     The receipt of cash in lieu of a fractional LDDS Share by an IDB
stockholder pursuant to the Merger will result in taxable gain or loss to such
stockholder for federal income tax purposes based on the difference between the
amount of cash received by such stockholder and such stockholder's basis in such
fractional share as set forth above. Such gain or loss should be a capital gain
or loss, provided the IDB Shares were held as a capital asset on the date of the
Merger.
 
     CERTAIN TAX CONSEQUENCES FOR PERSONS WHO ARE NOT UNITED STATES CITIZENS OR
RESIDENTS.  IDB stockholders who are not United States persons, as defined in
Section 7701(a)(30) of the Code, will generally be subject to the same U.S.
income tax consequences as U.S. persons (discussed above) in connection with the
Merger. Based on IDB's representation that it is not and has never been a U.S.
real property holding corporation, as defined in Section 897(c)(2) of the Code,
no U.S. withholding taxes will apply to LDDS Shares received by a foreign IDB
stockholder. Any dividends paid with respect to the LDDS Shares will be subject
to withholding, subject to any applicable treaty provisions applicable to the
holder.
 
     BECAUSE OF THE COMPLEXITY OF THE TAX LAWS, AND BECAUSE THE TAX CONSEQUENCES
OF ANY PARTICULAR STOCKHOLDER MAY BE AFFECTED BY MATTERS NOT DISCUSSED HEREIN,
IT IS RECOMMENDED THAT EACH STOCKHOLDER, OPTION HOLDER AND NOTE HOLDER CONSULT
HIS OR HER PERSONAL TAX ADVISOR CONCERNING THE APPLICABLE FOREIGN AND UNITED
STATES FEDERAL, STATE AND LOCAL INCOME TAX CONSEQUENCES OF THE MERGER.
 
                            THE LDDS SPECIAL MEETING
 
GENERAL
 
     This Joint Proxy Statement/Prospectus is being furnished to holders of LDDS
Common Stock in connection with the solicitation of proxies by the Board of
Directors of LDDS for use at the LDDS Special Meeting and any adjournments or
postponements thereof. At the LDDS Special Meeting, the shareholders of LDDS
will consider and vote upon (1) a proposal to approve the issuance of LDDS
Common Stock pursuant to the Merger Agreement, (2) a proposal to approve the
1995 Plan, and (3) any other business which may properly be brought before the
LDDS Special Meeting or any adjournments or postponements thereof. Each copy of
this Joint Proxy Statement/Prospectus which is being mailed or delivered to LDDS
shareholders is accompanied by an LDDS proxy card and a Notice of Special
Meeting.
 
     The issuance of LDDS Common Stock pursuant to the Merger Agreement is being
submitted for the approval of the shareholders of LDDS pursuant to the
requirements of the NASD applicable to companies whose securities are quoted on
the Nasdaq National Market. Pursuant to these requirements, the issuance of LDDS
Common Stock pursuant to the Merger Agreement must be approved by a majority of
the total votes cast by LDDS shareholders on such proposal at the LDDS Special
Meeting. See "Item 2. Approval of the LDDS Communications, Inc. 1995 Special
Performance Bonus Plan" for a discussion of the proposal to approve the 1995
Plan.
 
DATE, TIME AND PLACE
 
     The LDDS Special Meeting will be held at 515 East Amite St., Jackson,
Mississippi, on December 29, 1994 at   :    .m., local time.
 
                                       62
<PAGE>   73
 
RECORD DATE; VOTE REQUIRED
 
     The Board of Directors of LDDS has fixed the close of business on November
23, 1994, as the LDDS Record Date. On the LDDS Record Date, there were
outstanding and entitled to vote at the LDDS Special Meeting           shares of
LDDS Common Stock, 10,896,785 shares of Series 1 Preferred Stock and 2,000,000
shares of Series 2 Preferred Stock. On the LDDS Record Date, the shares of
Series 1 Preferred Stock and Series 2 Preferred Stock were convertible into
21,876,976 shares and 4,233,087 shares, respectively, of LDDS Common Stock.
 
     Holders of record of LDDS Common Stock as of the close of business on the
LDDS Record Date are entitled to one vote per share on any matter voted on at
the LDDS Special Meeting, whether voting as a class or voting together with LDDS
Preferred Stock. The holders of Series 1 Preferred Stock and Series 2 Preferred
Stock are entitled to vote, on an as-if-converted basis, together with holders
of LDDS Common Stock as a single class on the issuance of LDDS Common Stock
pursuant to the Merger Agreement and the proposal to approve the 1995 Plan. The
affirmative vote of the holders of at least a majority of the total votes cast
by the holders of the LDDS Common Stock, the Series 1 Preferred Stock and the
Series 2 Preferred Stock voting together as a class at the LDDS Special Meeting
is required to approve the issuance of LDDS Common Stock pursuant to the Merger
Agreement. Approval of the 1995 Plan requires that more votes be cast at the
LDDS Special Meeting in favor of the 1995 Plan than are cast against the 1995
Plan.
 
     The presence, either in person or by proxy, of the holders of a majority of
the votes entitled to be cast on the matter as of the LDDS Record Date is
necessary to constitute a quorum at the LDDS Special Meeting. Shares as to which
voting authority is withheld will be considered present for purposes of
determining the presence of a quorum at the LDDS Special Meeting but as not
entitled to vote, and not voted, for purposes of the approval of the issuance of
the LDDS Common Stock pursuant to the Merger Agreement. Shares as to which a
broker indicates it has no discretion to vote and which are not voted will be
considered not present at the LDDS Special Meeting for purposes of determining
the presence of a quorum and as unvoted for purposes of the approval of the
issuance of the LDDS Common Stock pursuant to the Merger Agreement. Shares voted
to "abstain" will be considered to be present for purposes of establishing a
quorum but will not have any effect on the proposal to approve the 1995 Plan.
Shares as to which a broker indicates it lacks authority to vote on such
proposal and which are not voted will be considered not present for purposes of
determining the existence of a quorum and the requisite majority vote.
 
     As of the LDDS Record Date for the LDDS Special Meeting, directors and
executive officers of LDDS and their affiliates (as a group) were entitled to
vote an aggregate of           shares of LDDS Common Stock and 10,896,785 shares
of Series 1 Preferred Stock (representing 21,876,976 shares of underlying LDDS
Common Stock), or approximately      % of the outstanding votes entitled to be
cast at the LDDS Special Meeting. All such directors and executive officers and
their affiliates have indicated their intention to vote their shares for the
approval of the issuance of LDDS Common Stock pursuant to Merger Agreement at
the LDDS Special Meeting and for the approval of the 1995 Plan.
 
VOTING AND REVOCATION OF PROXIES
 
     Shares of LDDS Common Stock which are represented by a proxy properly
executed and received prior to the vote at the LDDS Special Meeting will be
voted at the LDDS Special Meeting in the manner directed on the proxy card,
unless such proxy is revoked in advance of such vote. ANY LDDS SHAREHOLDER
RETURNING A BLANK EXECUTED PROXY CARD WILL BE DEEMED TO HAVE APPROVED THE
ISSUANCE OF LDDS COMMON STOCK PURSUANT TO THE MERGER AGREEMENT AND THE PROPOSAL
TO APPROVE THE 1995 PLAN.
 
     Any shareholder of LDDS giving a proxy may revoke it at any time prior to
the vote at the LDDS Special Meeting. Shareholders of LDDS wishing to revoke a
proxy prior to the time it is voted may do so by delivering to the Secretary of
LDDS at 515 East Amite Street, Jackson, Mississippi 39201-2702, a written notice
of revocation bearing a later date than the proxy or a later dated proxy
relating to the same shares or by attending the LDDS Special Meeting and voting
in person. Attendance at the LDDS Special Meeting will not in itself constitute
the revocation of a proxy.

     The Board of Directors of LDDS is not currently aware of any business to be
brought before the LDDS Special Meeting other than that described herein. If,
however, other matters are properly brought before the LDDS Special Meeting, or
any adjournments or postponements thereof, the persons appointed as proxies will
have discretionary authority to vote the shares represented by duly executed
proxies in accordance with their discretion and judgment as to the best interest
of LDDS.
 
SOLICITATION OF PROXIES
 
     LDDS will bear the costs of soliciting proxies. Proxies will initially be
solicited by LDDS by mail, but directors, officers and selected other employees
of LDDS may also solicit proxies in person or by telephone or telegraph.
Directors, executive officers and any other employees of LDDS who solicit
proxies will not be specially compensated for such services. Brokerage houses,
nominees, fiduciaries, and other custodians will be requested to forward
soliciting materials to beneficial owners and will be reimbursed for their
reasonable out-of-pocket expenses incurred in sending proxy materials to
beneficial owners. LDDS has also engaged Corporate Investor Communications,
Inc., a professional soliciting organization, to aid in the solicitation of
proxies. LDDS estimates that the fee for such services will not exceed $7,500
plus reimbursable out-of-pocket expenses.
 
HOLDERS OF LDDS COMMON STOCK ARE REQUESTED TO COMPLETE, DATE AND SIGN THE
ACCOMPANYING LDDS PROXY CARD AND RETURN IT PROMPTLY IN THE ENCLOSED
POSTAGE-PREPAID ENVELOPE.
 
FUTURE PROPOSALS OF SHAREHOLDERS
 
     All proposals of shareholders intended to be presented at the 1995 annual
meeting of shareholders of LDDS must be received by LDDS not later than December
30, 1994, for inclusion in LDDS's 1995 proxy statement and form of proxy
relating to the 1995 annual meeting. Upon timely receipt of any such proposal,
LDDS will determine whether or not to include such proposal in the proxy
statement and proxy in accordance with applicable regulations and provisions
governing the solicitation of proxies.
 
     Under the Bylaws of LDDS, shareholders entitled to vote in the election of
directors may nominate one or more persons for election as directors only if

arrangements or understandings between the shareholder and each nominee and any
other person or persons (naming such person or persons) pursuant to which the
nomination or nominations are to be made by the shareholder; (d) such other
information regarding each nominee proposed by such shareholder as would be
required to be included in a proxy statement filed pursuant to the proxy rules
of the Commission; and (e) the consent of each nominee to serve as a director of

                            THE IDB SPECIAL MEETING
 
GENERAL
 
     This Joint Proxy Statement/Prospectus is being furnished to holders of IDB
Common Stock in connection with the solicitation of proxies by the Board of
Directors of IDB for use at the IDB Special Meeting and any adjournments or
postponements thereof. At the IDB Special Meeting, the stockholders of IDB will
consider and vote upon a proposal to approve the Merger Agreement and the
transactions contemplated thereby and vote upon any other business which may
properly be brought before the IDB Special Meeting or any adjournments or
postponements thereof. If approved by the IDB and LDDS stockholders, the Merger
may be consummated without regard to whether the WilTel Acquisition is
 
                                       64
<PAGE>   75
 
consummated. Each copy of this Joint Proxy Statement/Prospectus which is being
mailed or delivered to IDB stockholders is accompanied by an IDB proxy card and
a Notice of Special Meeting.
 
     This Joint Proxy Statement/Prospectus is also furnished by LDDS to each
holder of IDB Common Stock as a Prospectus in connection with the issuance by
LDDS of shares of LDDS Common Stock upon the consummation of the Merger. This
Joint Proxy Statement/Prospectus and the Notice of Special Meeting and proxy
card are being first mailed to stockholders of IDB on November 30, 1994.
 
DATE, TIME AND PLACE
 
     The IDB Special Meeting will be held at 515 East Amite St., Jackson,
Mississippi, on December 29, 1994 at  :   .m., local time.
 
RECORD DATE; VOTE REQUIRED
 
     The Board of Directors of IDB has fixed the close of business on November
23, 1994 as the IDB Record Date. On the IDB Record Date, there were
shares of IDB Common Stock outstanding and entitled to vote at the IDB Special
Meeting and no shares of IDB preferred stock outstanding. Each share of IDB
Common Stock will entitle the holder to one vote at the IDB Special Meeting. A
majority of shares of IDB Common Stock outstanding on the IDB Record Date
represented at the IDB Special Meeting in person or by proxy will constitute a
quorum for purposes of the IDB Special Meeting. The shares represented by
proxies marked "abstain" will be counted toward the requirements for a quorum.
Abstentions, however, will not constitute a vote "for" or "against" approval of
the Merger Agreement and the transactions contemplated thereby and thus have the
practical effect of voting against the Merger Agreement and the transactions
contemplated thereby because an abstention as to each share of IDB Common Stock
is one less vote for approval of the Merger Agreement and the transactions
contemplated thereby. Shares of IDB Common Stock referred to as "broker
non-votes" will be treated as shares that are present and entitled to vote for
purposes of determining the presence of a quorum. However, if a broker or
nominee has physically indicated on the proxy that it does not have
discretionary authority to vote, those shares will be treated as not present and
not entitled to vote with respect to approval of the Merger Agreement and the
transactions contemplated thereby. Each outstanding share is entitled to one
vote on each matter properly brought before the IDB Special Meeting. The
affirmative vote of the holders of at least a majority of the outstanding shares
of IDB Common Stock is required to approve the Merger Agreement and the
transactions contemplated thereby.
 
     As of the IDB Record Date for the IDB Special Meeting, directors and
executive officers of IDB and their affiliates (as a group) were entitled to
vote an aggregate of 5,184,463 shares of IDB Common Stock, or approximately   %
of the outstanding shares entitled to vote at the IDB Special Meeting. All IDB
directors, who collectively are entitled to vote 5,180,423 shares of IDB Common
Stock, have indicated their intention to vote their shares for the approval of
the Merger Agreement and the transactions contemplated thereby at the IDB
Special Meeting.
 
VOTING AND REVOCATION OF PROXIES
 
     Shares of IDB Common Stock which are represented by a proxy properly
executed and received prior to the vote at the IDB Special Meeting will be voted
at the IDB Special Meeting in the manner directed on the proxy card, unless such
proxy is revoked in advance of such vote. ANY IDB STOCKHOLDER RETURNING A BLANK
EXECUTED PROXY CARD WILL BE DEEMED TO HAVE APPROVED THE MERGER AGREEMENT AND THE
TRANSACTIONS CONTEMPLATED THEREBY. Failure to return a properly executed proxy
card or to vote in person at the IDB Special Meeting will have the practical
effect of a vote against the proposals under consideration.
 
     Any stockholder of IDB giving a proxy may revoke it at any time prior to
the vote at the IDB Special Meeting. Stockholders of IDB wishing to revoke a
proxy prior to the time it is voted may do so by delivering to the Secretary of
IDB at 10525 West Washington Boulevard, Culver City, California 90232-1922, a
written notice of revocation bearing a later date than the proxy or a later
dated proxy relating to the same shares or by attending the IDB Special Meeting
and voting in person. Attendance at the IDB Special Meeting will not in itself
constitute the revocation of a proxy.

HOLDERS OF IDB COMMON STOCK ARE REQUESTED TO COMPLETE, DATE AND SIGN THE
ACCOMPANYING IDB PROXY CARD AND RETURN IT PROMPTLY IN THE ENCLOSED
POSTAGE-PREPAID ENVELOPE.
 
FUTURE PROPOSALS OF STOCKHOLDERS
 
     All proposals of IDB stockholders intended to be presented at the 1995
annual meeting of Stockholders must be received by IDB not later than March 15,
1995, for inclusion in IDB's 1995 proxy statement and form of proxy relating to
the 1995 annual meeting. Upon timely receipt of any such proposal, IDB will
determine whether or not to include such proposal in the proxy statement and
proxy in accordance with applicable regulations and provisions governing the
solicitation of proxies. IDB does not expect to convene a 1995 annual meeting of
stockholders if the Merger is consummated.
 
                               DISSENTERS' RIGHTS
 
     Pursuant to Section 262(b) of the Delaware General Corporation Law, IDB
stockholders are not entitled to dissenters' or appraisal rights in connection
with the Merger, because: (i) shares of IDB Common Stock were, at the IDB Record
Date, designated as a Nasdaq National Market security; (ii) IDB stockholders
will not be required to accept anything in exchange for their IDB Shares other
than LDDS Shares (i.e., shares of stock which are designated as a Nasdaq
National Market security) and cash in lieu of fractional shares of such stock;
and (iii) the Restated Certificate of Incorporation of IDB does not otherwise
provide IDB stockholders with dissenters' or appraisal rights applicable to the
Merger. LDDS shareholders are not entitled to dissenters' or appraisal rights
with respect to the Merger. See "Comparative Rights of Shareholders -- Appraisal
Rights of Dissenting Shareholders."
 
                           INFORMATION REGARDING LDDS
 
     The following briefly describes the business of LDDS. Additional
information regarding LDDS is contained in its filings with the Commission
pursuant to the Exchange Act. See "Available Information" and "Incorporation by
Reference."
 
BUSINESS OF LDDS
 
     LDDS is the fourth largest long distance telecommunications company in the
United States, based on 1993 revenues. The company provides long distance
telecommunications services through its digital fiber optic and digital
microwave network to business and residential customers, with service to points
throughout the nation and to more than 220 foreign countries. The products and
services provided by LDDS include: switched and dedicated long distance
products, 800 services, calling cards, operator services, private lines, frame
relays,
 
                                       66
<PAGE>   77
 
debit cards, conference calling services, advanced billing systems and broadcast
fax services. Based on FCC statistics as of December 31, 1993 (the most recent
statistics available), LDDS's share of total toll service revenues for 1993 was
1.5%.
 
     LDDS was organized in 1983. Its operations have grown as a result of
management's emphasis of a four-point growth strategy, which includes internal
growth, the selective acquisition of smaller long distance companies with
limited geographic service areas and market shares, the consolidation of certain
third-tier long distance carriers with larger market shares, and international
expansion. On September 15, 1993, a three-way merger occurred whereby (i) MCC
merged with and into Resurgens, and (ii) LDDS-TN merged with and into Resurgens
(previously defined as the "Prior Mergers").
 
     At the time of the Prior Mergers, the name of Resurgens, the legal
survivor, was changed to LDDS Communications, Inc. and the separate corporate
existences of LDDS-TN and MCC terminated. For accounting purposes, however,
LDDS-TN was the survivor because the former shareholders of LDDS-TN acquired
majority ownership of LDDS. Accordingly, unless otherwise indicated, all
historical information presented herein reflects the operations of LDDS-TN.
 
     As of             , 1994, there were           shares of LDDS Common Stock,
10,896,785 shares of Series 1 Preferred Stock (representing 21,876,976
underlying shares of LDDS Common Stock), and 2,000,000 shares of Series 2
Preferred Stock (representing 4,233,087 underlying shares of LDDS Common Stock).
For the fiscal year ended December 31, 1993, LDDS reported revenues of $1.14
billion, net income of $104.2 million and net income applicable to common
shareholders of $93.7 million. For the nine months ended September 30, 1994,
LDDS reported revenues of $1.3 billion, net income of $118.7 million and net
income applicable to common shareholders of $97.8 million.
 
     LDDS's principal executive offices are located at 515 East Amite Street,
Jackson, Mississippi 39201-2702 and its telephone number is (601) 360-8600.
 
RECENT DEVELOPMENTS
 
     WILTEL ACQUISITION.  On August 22, 1994, LDDS announced that it had signed
a definitive agreement (the "WilTel Agreement") with Williams to acquire all of
the stock of Williams' subsidiary, WilTel, for $2.5 billion in cash, subject to
adjustment (previously defined as the "WilTel Acquisition"). This transaction,
which is expected to close on or before February 1, 1995, is subject to
approvals by the FCC and various state PUCs. The Hart-Scott-Rodino Act waiting
period for the WilTel Acquisition was terminated on September 28, 1994. LDDS and
IDB shareholders will not be asked to approve the WilTel Acquisition. The WilTel
Acquisition will be treated as an asset purchase for federal income tax purposes
pursuant to a joint election under Section 338(h)(10) of the Code. The WilTel
Acquisition is not a condition to the consummation of the Merger, and there can
be no assurance that the WilTel Acquisition will be consummated.
 
     The following companies will not be acquired by LDDS pursuant to the WilTel
Acquisition and will continue to be subsidiaries of Williams: WilTel
Communications Systems, Inc., a distributor of customer-premise equipment;
WilTel Data Network Services, Inc., a provider of data transmission equipment;
VYVX, Inc. ("VYVX"), a subsidiary of Williams and a provider of video
transmission links for television networks and other users; and WilTel Financial
Corporation, a financial services company.
 
     Additionally, under the terms of the WilTel Agreement, certain assets and
liabilities of WilTel will be excluded from the transaction, including cash, tax
asset and liability accounts, debt, and payables and receivables of WilTel with
Williams and other Williams subsidiaries. Further, at closing, a current ratio
adjustment will be made based on the existing current ratio at December 31,
1993, and a capital expenditure adjustment will be made based on actual capital
expenditures as compared to the 1994 capital expenditure budget. The WilTel
Agreement also provides that interest on the purchase price will accrue in the
event that the closing date occurs after January 2, 1995, at a specified prime
rate, and penalties will be paid by LDDS ranging from $25 million to $50 million
if the transaction is cancelled under certain circumstances. See "Pro Forma
Combining Financial Statements".

     LDDS believes the WilTel Acquisition would create the following
opportunities: (i) networking efficiencies associated with owning the WilTel
nationwide fiber optic network rather than leasing similar capacity from other
providers at a higher cost; (ii) operational efficiencies generated through the
consolidation of certain selling, general and administrative functions; (iii)
marketing growth opportunities associated with providing additional services to
customers; and (iv) expansion opportunities through the combination of the LDDS
and WilTel international businesses. No assurance can be given that any of these
efficiencies or opportunities will materialize. See "Risk Factors -- Factors
Concerning LDDS -- Acquisition of WilTel" and "Risk Factors -- Factors
Concerning LDDS and IDB -- Acquisition Integration."
 
     WILTEL.  WilTel, through its subsidiaries, is a full service
telecommunications company providing data and voice transmission services
worldwide. WilTel provides services through two business units: WilTel, Inc.
("WilTel US"), a private line, switched long distance and enhanced services
provider to domestic markets; and WilTel International, Inc. ("WilTel
International"), a private line, switched long distance and enhanced services
provider to foreign markets. A third unit, WilTel Undersea Cable, has been
formed for the specific purpose of constructing a fiber optic cable from the
United States to Cuba.
 
     WilTel US offers fully integrated service systems providing customized
solutions for end users telecommunications needs, including data and voice
offerings. WilTel US provides such service offerings through a nationwide common
carrier network of approximately 11,000 miles of fiber optic cable and digital
microwave facilities, making it the fourth largest nationwide network. Through
network sharing and lease agreements with other carriers, WilTel US has access
to approximately 40,000 miles of additional digital transmission network
facilities. With a total network consisting of approximately 51,000 miles,
WilTel US reaches substantially all major cities in the continental United
States.
 
     WilTel US provides its services to regional and national common carriers
("OCCs") as well as commercial end users nationwide. Additionally, WilTel US's
products and services are used indirectly by thousands of residential and
business users who purchase their telecommunications services from WilTel US's
OCC customers. Since WilTel US's entry into the switched services market in
1991, switched service activity has continued to grow. In 1993, switched
services accounted for approximately one-third of WilTel US's total revenues.
The largest users of WilTel US products and services are OCCs, which purchase
capacity on WilTel US's network and sell long distance services directly to end
users. Contractual arrangements with OCCs generally range from one to five
years; however, there can be no assurance that any of these existing agreements
with WilTel US will be renewed upon expiration.
 
     Competition for OCC customers continues to increase as the number of OCCs
in the marketplace has decreased due to recent acquisition activity. WilTel US's
growth in the dedicated circuit and switched services markets is in part
dependent upon the continued success of the OCCs. The OCCs are smaller or
regionally based carriers and resellers who may sell and bill certain of WilTel
US's products and services under their own name.
 
     WilTel US's commercial (i.e., non-OCC) customer base includes corporations,
financial institutions and governmental entities, including many Fortune 500
companies. Contractual arrangements with commercial customers generally range
from one to five years, although service is also provided on a monthly basis; no
assurance can be given that any of the arrangements will be renewed upon
expiration. WilTel US's product and service offerings allow commercial customers
the opportunity to develop customized solutions with respect to their voice,
data and video transmissions. WilTel US also provides public switched services
to these and other customers.
 
     WilTel International allows WilTel to offer its customers
telecommunications services worldwide. WilTel International provides
communications between domestic and foreign sites by allowing a single point of
contact for customers desiring telecommunications services internationally. It
is anticipated that if the worldwide marketplace continues its move toward
deregulation and other obstacles to entry into the international marketplace are
removed, WilTel will continue to increase its service in the international
marketplace.
 
                                       68
<PAGE>   79
 
     WilTel is generally subject to the same regulatory environment and
competitive pressures as LDDS and IDB. See "Risk Factors -- Factors Concerning
LDDS and IDB." Although fiber-optic networks for long distance transmission are
now widely used, it is possible that WilTel could be adversely affected by
changing technology. The telecommunications industry is in a period of rapid
technological evolution, marked by the introduction of new product and service
offerings. None of LDDS, IDB and WilTel can predict which of many possible
future product and service offerings will be important to maintain their
respective competitive positions or what expenditures will be required to
develop and provide such products and services.
 
     Recognizing the unique nature of fiber optic capacity usage for video
transmission, WilTel signed an agreement, effective January 1, 1994, with VYVX,
conveying to VYVX one restricted fiber optic strand throughout the entire WilTel
US fiber optic network, for video and radio transmission applications only,
along with an interest in related optics equipment. WilTel US continues to
service and maintain the fiber strand and optronics owned by VYVX pursuant to a
service and maintenance agreement.
 
     WilTel has sold to independent entities and leased back its microwave
system and its Kansas City to Los Angeles fiber optic system over primary lease
terms ranging from 15 to 20 years. The leases have renewal options permitting
WilTel to extend the leases for terms expiring during the years 2012 to 2019 and
purchase options based upon the fair market value. Williams has provided a
guarantee for the benefit of the purchasing entities and their lenders for
WilTel's lease payment obligations, which is conditioned upon certain financial
covenants of Williams.
 
     WilTel's rights-of-way for its fiber optic cable are typically held under
leases, easements, licenses or governmental permits, although most of the
terminals and regeneration stations on the fiber system and the tower sites on
the microwave portion of the system are held under lease, governmental permit or
are owned in fee. WilTel owns and leases various offices, warehouses, terminal
sites, switch location sites and regeneration station sites. All other major
equipment and facilities are owned in fee and are operated, constructed and
maintained pursuant to rights-of-way, easements, permits, licenses or consents
on or across properties owned by others. It also leases a fiber system in
Connecticut under a 20-year term expiring in 2006.
 
     FINANCING OF WILTEL ACQUISITION.  LDDS has obtained underwritten
commitments for loan facilities aggregating $3.41 billion both to finance the
WilTel Acquisition and to refinance LDDS's existing credit facilities. The
commitments would be funded through Facility A, a $2.16 billion, six-year
reducing revolving credit facility, and Facility B, a $1.25 billion, two-year
term facility. Principal payments on Facility A would commence in varying
quarterly amounts on September 30, 1996 with the final installment due on
December 31, 2000. Facility B would mature in a single installment on December
31, 1996. Facility A and Facility B would bear interest at one of several
interest rate options, payable quarterly, similar to those in effect under
LDDS's existing credit facilities. The facilities would also be subject to an
annual commitment fee not to exceed 0.375% of any unborrowed portion of Facility
A and Facility B. LDDS's credit facilities are and would be unsecured and
require compliance with certain financial and other operating covenants which
limit, among other things, the incurrence of additional indebtedness by LDDS,
and prohibit the payment of cash dividends to LDDS's shareholders without prior
approval by the banks. See "Risk Factors -- Risks of Increased Financial
Leverage; Debt Service, Interest Rate Fluctuations, Possible Reduction in
Liquidity, Dividend Restrictions, and Other Restrictive Covenants," "Information
Regarding LDDS -- Recent Developments" and "Management's Discussion and Analysis
of the Pro Forma Combining Financial Statements."
 
     Certain historical financial information concerning the WilTel Network
Services operations of WilTel is included in LDDS's Current Report on Form 8-K
dated August 22, 1994 (filed September 8, 1994) (as amended by Current Report on
Form 8-K/A filed November 17, 1994). See "Available Information" and
"Incorporation by Reference." For pro forma, post-Merger financial information
regarding LDDS (with and without WilTel) and IDB, see "Summary
Information -- Recent Developments Regarding LDDS," "Pro Forma Combining
Financial Statements" and "Management's Discussion and Analysis of the Pro Forma
Combining Financial Statements."

EXECUTIVE COMPENSATION
 
  SUMMARY COMPENSATION TABLE
 
     Subsequent to the Prior Mergers on September 15, 1993, Messrs. Ebbers,
Cannada and Porter, formerly associated with LDDS-TN, have served LDDS in their
current capacities. After the Prior Mergers, none of the Resurgens' executive
officers served LDDS in an executive officer capacity. Therefore, the following
table
sets forth the compensation of the named executive officers of LDDS-TN or the
surviving corporation in the Prior Mergers for the three years ended December
31, 1993, including compensation from LDDS-TN. Information concerning
compensation of the named executive officers of Resurgens for its three fiscal
years ended June 30, 1993, is presented below under the caption "Compensation of
Former Resurgens Executive Officers." All stock information shown below also is
adjusted for the Prior Mergers, whereupon each share of Class A Common Stock of
LDDS-TN was converted into .9595 of a share of LDDS Common Stock, and options
were similarly adjusted.

  EMPLOYMENT AGREEMENTS
 
     In connection with the ATC Merger, LDDS-TN assumed the employment agreement
between Norman Klugman and ATC. The agreement provided that Mr. Klugman would
serve until June 30, 1993, and receive an annual base salary of at least
$260,200. Mr. Klugman resigned from his position with LDDS-TN effective June 30,
1993.
 
     On February 4, 1992, Resurgens entered into employment agreements with each
of John D. Phillips and Michael P. Marshall, Resurgens' Chief Executive Officer
and a Co-Chairman of the Board, respectively. Each of the agreements provided
for the employment of Messrs. Phillips and Marshall in the capacities indicated
above for an initial three-year term at a base salary of $275,000 per year. In
addition to cash compensation, Messrs. Phillips and Marshall were entitled to
incentive compensation under Resurgens' stock option plans and to participate in
Resurgens' benefit plans providing health, disability and death benefits. Under
the terms of each agreement, neither Mr. Phillips nor Mr. Marshall would be paid
his salary if he elected to terminate his employment agreement prior to the
expiration of the term. Pursuant to their terms, if such agreements were
terminated by Resurgens for any reason other than cause, each of Mr. Phillips
and Mr. Marshall would be entitled to continue to receive the compensation
provided under the respective agreements for the remainder of the term.
 
     In connection with the consummation of the Prior Mergers, Messrs. Marshall
and Phillips agreed to terminate their respective employment agreements and
receive bonuses from Resurgens in an aggregate amount of $917,000 ($458,500
each). Messrs. Marshall and Phillips used such monies to repay (i) certain
advances made by Resurgens to each of them, plus accrued and unpaid interest on
such advances, and (ii) a portion of two separate promissory notes each in the
principal amount of $250,000 which were executed in 1989 by Messrs. Marshall and
Phillips. Such notes have been paid in full. Neither Mr. Marshall nor Mr.
Phillips is currently employed by LDDS.
 
                           INFORMATION REGARDING IDB
 
     The following briefly describes the business of IDB. Additional information
regarding IDB is contained in its filings with the Commission pursuant to the
Exchange Act. See "Additional Information" and "Incorporation by Reference."
 
BUSINESS OF IDB
 
     IDB operates a domestic and international communications network providing
international private line and public switched long distance telephone services,
facsimile and data connections, television and radio transmission services and
mobile satellite communications capabilities. IDB was established in 1983 to
provide transmission of sporting and music events to radio stations nationally.
Aided by the AT&T divestitures in 1984 and the opening of international
telecommunications markets, IDB has become a full service provider of
international telecommunications services as well as specialized broadcasting
services. IDB has expanded rapidly through the growth of its existing businesses
as well as through the selective acquisition of complementary companies which
have provided strategic facilities, international operating agreements and
customers. IDB operates through four service units: IDB WorldCom, IDB Broadcast,
IDB Mobile and IDB Systems. Based on FCC statistics as of December 31, 1992 (the
most recent international statistics available), on a combined IDB, WorldCom and
TRT basis, IDB's share of total net revenues from U.S.-based international long
distance communications services in 1992 was 2.2%.
 
     As of November 2, 1994, there were 74,456,003 shares of IDB Common Stock
and no shares of preferred stock outstanding. For the fiscal year ended December
31, 1993, IDB reported revenues of $339.4 million, income before preferred stock
dividends of $12.2 million and net income available to common stockholders of
$11.0 million. For the nine months ended September 30, 1994, IDB reported
revenues of $378.1 million and net loss of $170.5 million.
 
     IDB's principal executive offices are located at 10525 West Washington
Boulevard, Culver City, California 90232-1922 and its telephone number is (213)
870-9000.

RECENT DEVELOPMENTS
 
     RESIGNATION OF INDEPENDENT AUDITORS.  On May 23, 1994, Deloitte resigned as
IDB's independent auditors. Deloitte has stated it resigned as a result of
events surrounding the release and reporting of IDB's financial results for the
first quarter of 1994. In submitting its resignation, Deloitte informed IDB
management and the Audit Committee of the IDB Board of Directors that there had
been a serious breakdown in IDB's process of identifying, analyzing and
recording IDB's business transactions which prohibited Deloitte from the
satisfactory completion of a quarterly review, and that Deloitte was no longer
willing to rely on IDB management's representations regarding IDB's interim
financial statements. IDB announced Deloitte's resignation on May 31, 1994 and
information concerning the resignation is contained in IDB's Current Report on
Form 8-K filed with the Commission on May 31, 1994, as amended by Form 8-K/A
filed with the Commission on November 21, 1994. On June 24, 1994, upon the
recommendation of the independent members of IDB's Audit Committee, IDB retained
Arthur Andersen LLP as its new independent auditors. On August 22, 1994, IDB
filed Amendment No. 1 on Form 10-Q/A restating its 1994 first quarter results in
order to eliminate previously recorded items, which items were among those as to
which Deloitte had expressed disagreement. See "Available Information" and
"Incorporation by Reference."
 
     STOCKHOLDER LITIGATION.  Between June 1, 1994 and June 6, 1994, 22 class
action complaints were filed in the U.S. District Court for the Central District
of California on behalf of persons who purchased IDB Common Stock and IDB Notes
naming as defendants IDB and the directors and certain officers of IDB,
including Mr. Sudikoff, certain underwriters of IDB securities and other
parties. The complaints allege violations of the federal securities laws for
disseminating allegedly false and misleading statements concerning IDB's
earnings and accounting practices. These claims are asserted under one or more
provisions of the federal securities laws including Sections 10(b) and 20(a) of
the Exchange Act and Sections 11, 12(2) and 15 of the Securities Act. In
addition, one of the complaints alleges similar claims under the California
Corporations Code.
 
     On June 7, 1994, Robert S. Muldowney filed a stockholder derivative action
in the U.S. District Court for the Central District of California against IDB,
as a nominal defendant, and the directors and certain officers of IDB, including
Mr. Sudikoff, alleging breaches of fiduciary duty and gross negligence based on
substantially the same facts alleged in the class action lawsuits.
 
     Each class action complaint seeks damages suffered by the class and the
costs of the suit, including attorneys' fees. In addition, certain of the class
action complaints also seek punitive damages and injunctive relief. The
California derivative action seeks recovery of all damages suffered by IDB, with
interest thereon, as well as the derivative plaintiff's costs and attorneys'
fees. In addition, certain plaintiffs have alleged violations of the federal
securities laws by Hambrecht & Quist and the other co-managers of public
offerings of IDB securities in August 1993 and November 1993.
 
     On July 17, 1994, the District Court ordered the 22 class action complaints
and the California derivative action consolidated before Judge Richard Gadbois
as one action captioned In re IDB Communications Group, Inc. Securities
Litigation (Case No. CV-94-3618-RG(JGx)). A consolidated and amended complaint
was filed in the District Court on November 18, 1994.
 
     On July 1, 1994, George G. Steele filed a stockholder derivative action in
the Chancery Court for New Castle County, Delaware against IDB, as a nominal
defendant, and the directors and certain officers of IDB, including Mr. Sudikoff
(Steele v. Sudikoff et al., Civ. Action No. 13595), alleging breach of their
fiduciary duties to IDB by trading on inside information, accepting bonuses
based on false and inflated IDB financial results and exposing IDB to liability
under the securities laws. The plaintiff seeks restitution to IDB, injunctive
relief, costs and attorneys' fees.
 
     On September 21, 1994, Michael S. Hassani filed a class action in the
Superior Court of the State of California, County of Los Angeles, against IDB
and its current directors and certain executive officers, including Mr.
Sudikoff, and Deloitte (Hassani v. IDB Communications Group, Inc., Civ. No. BC
112906),
 
                                       77
<PAGE>   88
 
alleging violations of the California Corporations Code, breaches of fiduciary
duty and abuse of control. The complaint seeks compensatory, special and
punitive damages, prejudgment interest and the costs of the suit, including
attorneys' fees on behalf of certain purchasers of IDB Common Stock.
 
     IDB is a party to indemnification agreements with certain of the other
defendants in the actions described above, including IDB's officers and
directors (see "Comparative Rights of Shareholders -- Indemnification of
Directors and Officers"), certain selling shareholders and certain underwriters.
IDB's officers and directors are not covered by any applicable liability
insurance. LDDS has agreed to provide indemnification to IDB's officers and
directors under certain circumstances. See "Plan of Merger -- Interests of
Certain Persons in the Merger -- Indemnification."
 
     On November 18, 1994, IDB, LDDS and representatives of the plaintiffs in
the foregoing litigation entered into a Stipulation of Settlement (the
"Stipulation"). The Stipulation provides that all claims that were or could have
been asserted by the plaintiffs against IDB or any of the other defendants in
the consolidated action, or on behalf of or by IDB against IDB directors and
officers will, subject to the fulfillment of certain conditions precedent and
the approval of the court, be settled and released and the litigation dismissed
in its entirety with prejudice in exchange for payments totalling $75.0 million.
The conditions precedent to the settlement include completion of the Merger,
timely payment of settlement funds to the escrow agents for the class action and
derivative action plaintiffs, and dismissal of the Delaware Chancery Court
derivative action and California state court class action. The Stipulation
terminates automatically in the event that Court approval is not obtained or any
of the other conditions precedent listed in the Stipulation do not occur, unless
counsel for the class action and derivative action plaintiffs and counsel for
IDB and LDDS mutually agree in writing to proceed with the Stipulation.
Consequently, there can be no assurance that the litigation will be settled and
dismissed on the terms described herein or at all.
 
     INVESTIGATIONS AND OTHER PROCEEDINGS.  On June 9, 1994, the Commission
issued a formal order of investigation concerning certain matters, including
IDB's financial position, books and records and internal controls, and trading
in IDB securities on the basis of non-public information by certain persons and
entities. The Commission has issued subpoenas to IDB and others, including Mr.
Sudikoff, in connection with its investigation. The NASD and other
self-regulatory bodies have also made inquiries of IDB concerning similar
matters. IDB is cooperating with the Commission's investigation and the other
inquiries and is in the process of complying with the subpoenas it has received.
 
     In October, 1994, the U.S. Attorney's Office for the Central District of
California issued grand jury subpoenas to IDB seeking documents relating to
IDB's first quarter results and the Deloitte resignation. IDB has been informed
that a criminal investigation has commenced and is cooperating with the U.S.
Attorney's Office.
 
     OTHER LITIGATION.  On August 20, 1994, SynTech filed a complaint in the
U.S. District Court for the District of Columbia alleging that IDB Mobile is
infringing upon SynTech's copyrights in certain computer software. On September
7, 1994, IDB Mobile filed counterclaims against SynTech for, among other things,
breach of contract and interference with IDB Mobile's contracts with its
customers. Both parties have filed motions for summary judgment, which were
heard on November 16, 1994. The parties are awaiting the court's ruling
regarding their respective motions for summary judgment.
 
     On October 12, 1994, Community Network Services, Inc., a reseller of local
and long distance telephone service in New York, filed a complaint in the U.S.
District Court for the Southern District of New York (94 Civ. 7383 (JFK))
alleging breach of contract, false advertising under the Lanham Act and a
violation of the Racketeering and Corrupt Organization Act (RICO) based on IDB's
termination of service to the plaintiff.
 
     On October 21, 1993, Euronet, Incom, Benjamin Levovitz and Eli Lior filed a
complaint in the U.S. District Court for the Southern District of New York
against IDB and certain IDB personnel, alleging that IDB breached an oral
agreement to enter into a joint venture with Euronet and that the employee
defendants committed fraud by failing to disclose that IDB had entered into a
similar joint venture with a
 
                                       78
<PAGE>   89
 
competitor of Euronet. The plaintiffs also allege that IDB breached separate
agency and sales representative agreements and seek compensatory and punitive
damages and injunctive relief.
                            ------------------------
 
     IDB is unable at this time to predict the outcome of any of the foregoing
litigation, investigations or other proceedings. However, if determined
adversely to IDB, the impact of such matters on the financial position and
results of operations of IDB or, if the Merger is consummated, the consolidated
organization, could be material.
 
     RESTATED AND RECENT FINANCIAL RESULTS.  On August 1, 1994, IDB announced
that it would restate its reported financial results for the quarter ended March
31, 1994. The restatement eliminated approximately $6.0 million of pre-tax
income, approximately $5.0 million of which related to a sale of transponder
capacity and approximately $1.0 million of which related to purchase accounting
adjustments. On November 21, 1994, IDB filed Form 10-Q/A amendments to its
reported first and second quarter financial results making the previously
announced changes and reflecting the effect of IDB's method of accounting for
international long distance traffic, thereby reducing its first quarter net
income from $0.12 per share, as originally reported, to $0.05 per share and,
when combined with adjustments for income tax effects, increasing its second
quarter net loss from $0.20 per share, as originally reported, to $0.27 per
share.
 
     For its third quarter ended September 30, 1994, IDB reported a net loss,
after income taxes, of $154.7 million or $2.08 per share on revenues of $131
million. For the nine months ended September 30, 1994, IDB reported a net loss,
after income taxes, of $170.5 million or $2.31 per share on revenues of $378.1
million. Operating results in the third quarter of 1994 were significantly
affected by a stockholder litigation provision of $76.0 million, a reduction in
carrying value of certain IDB Broadcast assets of $35.0 million and a valuation
reserve of $18.3 million provided against deferred tax assets. The pre-tax loss
in the third quarter also reflects significant one time expenses of
approximately $2.0 million related to the Merger, and approximately $2.5 million
in accounting and legal expenses incurred in connection with the resignation of
Deloitte and the ensuing litigation. IDB also accrued approximately $2.4 million
for various non-income tax and related matters in the third quarter. See
"Available Information," "Incorporation by Reference," "Pro Forma Combining
Financial Statements" and "Management's Discussion and Analysis of the Pro Forma
Combining Financial Statements."
 
     As a result of these losses incurred by IDB in the third quarter, IDB is in
default with respect to certain covenants not relating to payment under its line
of credit with Bank of America. IDB is currently negotiating with Bank of
America to obtain a waiver of such default. There can be no assurance that any
such waiver will be obtained.
 
     RECENT EVENTS CONCERNING THE IDB BROADCAST UNIT.  On November 11, 1994, IDB
and Keystone, a privately-held provider of broadcast distribution services,
entered into non-binding letters of intent regarding a series of transactions
which, if consummated, will allow Keystone to operate and manage the Broadcast
Business of IDB. The letters of intent provide that Keystone will lease
substantially all of the tangible assets of the Broadcast Business pursuant to
an operating lease and will manage the contracts and other intangible assets of
the Broadcast Business through a management agreement. In connection with these
transactions, it is contemplated that IDB will also acquire for $6.0 million a
25% equity interest in Keystone to be held through a new partnership formed with
other Keystone investors. The following is a summary of the material provisions
of the letters of intent.
 
     The letters of intent provide that the lease agreement will be for an
initial term of 36 months, subject to renewal, at Keystone's discretion, for an
additional 24 months. Keystone will pay IDB $6.0 million on the closing date
and, during the initial lease term, quarterly lease payments in the aggregate
amount of $12.2 million. If the lease is renewed, lease payments in the
aggregate amount of $15.8 million will be paid by Keystone during the two year
renewal period.
 
     In addition, Keystone will be granted an option to acquire the tangible
assets of the Broadcast Business which will be exercisable at the end of the
initial 36-month lease term for $31 million or, if the lease is renewed, at any
time during the renewal period for the sum of (i) $19.3 million and (ii) the
aggregate amount of any remaining lease payments through the end of the renewal
period, with such aggregate sum discounted
 
                                       79
<PAGE>   90
 
at the rate of 8% per annum. The purchase price for the assets would be payable,
at the election of Keystone, in cash or by a subordinated promissory note of
Keystone which would accrue interest at the rate of 8% per annum. The promissory
note would be payable over a four-year period commencing on the date of its
issuance and would be secured by the leased assets. If the option is not
exercised, Keystone would be obligated to pay IDB an additional $2.1 million on
the lease termination date, subject to certain exceptions.
 
     The terms of the letters of intent also provide that Keystone will manage
the contracts and other intangible assets used in the Broadcast Business for a
period of up to 60 months pursuant to a management agreement. If Keystone
exercises its option to purchase the tangible assets under the lease, IDB will
also transfer the intangible assets to Keystone. Keystone will receive no fixed
fee as manager. Instead, each year IDB and Keystone will share in any net
profits of the Broadcast Business in the following manner: (i) IDB will receive
80% of the first $4.0 million of net profits, with Keystone retaining the
remaining 20% and (ii) IDB and Keystone will each receive one-half of any net
profits in excess of $4.0 million. IDB will be liable for any net losses of the
Broadcast Business and will have the right to terminate the management
agreement, as well as the lease, if the Broadcast Business reports net losses
for any two consecutive quarters or reports a net loss for any year.
 
     On September 23, 1994, IDB entered into a letter agreement with Autotote, a
publicly-held provider of computerized wagering systems, providing for the sale
by IDB of the simulcast assets of its broadcast business to Autotote for $13.5
million and the sublease by IDB of certain satellite transmission capacity to
Autotote on an ongoing basis. The simulcast assets consist primarily of
transportable broadcast equipment used for the live transmission of sporting
events via satellite in connection with wagering.
 
     Consummation of these transactions will be subject to the negotiation of
definitive agreements and receipt of board and various third party approvals.
There can be no assurance that any of these transactions will be consummated or,
if consummated, that they will be on the terms described above.

                    PRO FORMA COMBINING FINANCIAL STATEMENTS
 
     The following unaudited Pro Forma Combining Balance Sheet as of September
30, 1994 and unaudited Pro Forma Combining Income Statements for the nine months
ended September 30, 1994 and 1993, and for the years ended December 31, 1993,
1992 and 1991, illustrate the effect of the proposed Merger as if the Merger had
occurred at the beginning of the earliest period presented.
 
     Pursuant to the terms of the Merger Agreement, each holder of IDB Common
Stock will be entitled to receive a certain fraction of a share of LDDS Common
Stock based on an average closing trade price of LDDS Common Stock. These pro
forma financial statements have been prepared assuming the LDDS Share Value to
be equal to or greater than $22.00 resulting in an Exchange Ratio of 0.450867.
No assurance can be given as to the actual Exchange Ratio that will be utilized
in the Merger. For more information regarding the calculation and range of
possible Exchange Ratios, see "Plan of Merger -- General Description of the
Merger." The Merger will be accounted for as a pooling of interests.
 
     The following unaudited Pro Forma Combining Balance Sheet as of September
30, 1994 and the unaudited Pro Forma Combining Income Statements for the nine
months ended September 30, 1994 and for the year ended December 31, 1993 also
illustrate the effect of the WilTel Acquisition and the proposed financing
thereof. Pursuant to the terms of the acquisition agreement, LDDS will acquire
WilTel for cash payments of $2.5 billion, subject to adjustments. The WilTel
Acquisition will be accounted for as a purchase. Completion of the WilTel
Acquisition is not a condition to the consummation of the Merger, which, if
approved by IDB and LDDS shareholders may be consummated whether or not the
WilTel Acquisition is completed.
 
     These Pro Forma Combining Financial Statements should be read in
conjunction with the historical financial statements of LDDS, IDB and the
network services operations of WilTel which are incorporated by reference herein
and the LDDS Adjusted Historical Financial Statements and the IDB Adjusted
Historical Financial Statements which are set forth elsewhere herein.
 
     The Pro Forma Combining Financial Statements are presented for comparative
purposes only and are not intended to be indicative of actual results had the
transactions occurred as of the dates indicated above nor do they purport to
indicate results which may be attained in the future.

               NOTES TO PRO FORMA COMBINING FINANCIAL STATEMENTS
 
 1. The adjustments to the unaudited Pro Forma Combining Financial Statements do
    not give effect to direct transaction costs or any resulting restructuring
    costs associated with the consummation of the Merger. All such costs are
    estimated to be $50.0 million, which amount includes approximately $10.0
    million of direct transaction costs. The pro forma financial data do not
    give effect to any potential cost savings and synergies that could result
    from the Merger or the WilTel Acquisition. The pro forma data are not
    necessarily indicative of the operating results or financial position that
    would have occurred had the Merger or the WilTel Acquisition been
    consummated at the dates indicated, nor necessarily indicative of future
    operating results or financial position.
 
 2. These adjustments reflect the issuance of approximately 33.4 million shares
    of LDDS Common Stock in accordance with the assumed Exchange Ratio of
    0.450867 shares of LDDS Common Stock for each share of IDB Common Stock
    outstanding. The actual number of shares of LDDS Common Stock to be issued,
    pursuant to the Merger, will be based on the number of shares of IDB Common
    Stock outstanding immediately prior to the consummation of the Merger and
    the actual Exchange Ratio, based on the LDDS Share Value.
 
 3. These adjustments represent the elimination of certain assets and
    liabilities of WilTel that LDDS will not acquire as part of the WilTel
    Acquisition as set forth in the acquisition agreement. The assets and
    liabilities excluded include cash, tax asset and liability accounts with
    affiliates, accounts payable to affiliates and amounts due from affiliates,
    which consist of unsecured payables and receivables of WilTel with Williams.
 
 4. This adjustment reflects an increase to WilTel's working capital to comply
    with the required working capital amounts as set forth in the WilTel
    acquisition agreement. The acquisition agreement provides that upon the date
    of its acquisition by LDDS, WilTel will have a current ratio equal to the
    ratio existing at December 31, 1993. At September 30, 1994, this requirement
    would have necessitated a $27.7 million increase to WilTel's current assets.
 
 5. This adjustment reflects the excess of cost over net tangible assets
    acquired in the WilTel Acquisition. For purposes of allocating the
    acquisition costs among the various assets acquired, LDDS has tentatively
    considered the carrying value of the acquired assets to approximate their
    fair value, with all of the excess of such acquisition costs being
    attributed to goodwill. It is LDDS' intention, subsequent to the
    acquisition, to more fully evaluate the acquired assets and, as a result,
    the allocation of the acquisition costs among the tangible and intangible
    assets acquired may change.
 
 6. This adjustment reflects the capitalization of fees incurred to obtain the
    new credit facilities (see Note 8).
 
 7. This adjustment represents the replacement of the LDDS $123.0 million Senior
    Notes with a portion of the new credit facilities (see Note 8).
 
 8. This adjustment represents the incremental proceeds to be received under the
    new credit facilities for the purpose of financing the WilTel Acquisition
    and its related costs.
 
 9. These adjustments represent the elimination of WilTel's shareholders'
    investment accounts.
 
10. These columns represent historical results of operations.
 
11. These adjustments eliminate the revenues and corresponding line costs
    attributable to the intercompany traffic between LDDS and IDB.
 
12. These adjustments eliminate the revenues and corresponding line costs
    attributable to the intercompany traffic between LDDS/IDB pro forma combined
    operations and WilTel.
 
13. This adjustment reflects amortization over 40 years of the excess of cost
    over net tangible assets acquired in the WilTel Acquisition (see Note 5).
 
14. This adjustment reflects the amortization over 6 years of capitalized fees
    incurred to obtain the new credit facilities (see Note 6).
 
                                       88
<PAGE>   99
 
15. These adjustments represent interest savings to LDDS, as it will not acquire
    any of WilTel's debt in the WilTel Acquisition (see Note 3).
 
16. This adjustment represents the recognition of interest expense on the
    additional borrowings of LDDS to fund the WilTel Acquisition and related
    costs (see Note 8). The interest expense was calculated at an assumed rate
    of interest of 6.7%. A change of  1/8% in the assumed rate would affect
    interest expense by $2.6 million for the nine months ended September 30,
    1994 and by $3.5 million for the year ended December 31, 1993.
 
17. This adjustment reflects the interest savings resulting from the replacement
    of LDDS' $123.0 million Senior Notes with the new credit facilities (see
    Note 8).
 
18. These adjustments represent the tax effect of adjustments due to inclusion
    of the acquired operations. The tax provisions were calculated at a combined
    federal and state rate of 39% applied to items impacting taxable income.
    However, for the nine months ended September 30, 1994, the only item
    considered to have an impact upon LDDS/IDB Pro Forma Combined taxable income
    was the $76.0 million shareholder litigation settlement. Because of tax
    planning strategies, LDDS management believes that presently the shareholder
    litigation settlement is the only item contributing to IDB's results of
    operations for the nine months ended September 30, 1994 for which the
    combined company of LDDS and IDB is more likely than not to realize a tax
    benefit. After consummation of the Merger, LDDS management will review tax
    planning strategies in order to identify any additional net operating loss
    utilization available to the combined company of LDDS and IDB.
 
19. Pro forma per share data are based on the number of LDDS common and common
    equivalent shares that would have been outstanding had the Merger occurred
    on the earliest date presented.
 
20. The LDDS Adjusted Historical Income Statement for the year ended December
    31, 1993 includes (1) the effect of LDDS' acquisition in March 1993 of
    Dial-Net for cash payments of approximately $31.2 million and the issuance
    of 2.7 million shares of LDDS Common Stock valued at approximately $42.9
    million and (2) the effect of LDDS' acquisition in September 1993 of MCC and
    Resurgens for cash payments of approximately $150.0 million and the issuance
    of common and preferred stock valued at approximately $1.1 billion. The LDDS
    Adjusted Historical Income Statement assumes that the Prior Mergers and the
    Dial-Net acquisition occurred at the beginning of the earliest period
    presented. See "LDDS Adjusted Historical Income Statement" which is set
    forth elsewhere herein.
 
    The IDB Adjusted Historical Income Statement for the year ended December 31,
    1993 includes the effect of IDB's acquisition in September 1993 of TRT for
    cash payments of $1.0 million and the issuance of 10.1 million shares of IDB
    Common Stock valued at approximately $79.0 million. The IDB Adjusted
    Historical Income Statement assumes that the TRT acquisition occurred at the
    beginning of the earliest period presented. See "IDB Adjusted Historical
    Income Statement" which is set forth elsewhere herein.
 
    After consummation of the Merger, the financial statements of LDDS as of and
    for the year ended December 31, 1993, will be restated to reflect the
    combination of the financial position and results of operations of LDDS and
    IDB. Such financial statements will report revenues of $1.5 billion, net
    income available to common shareholders of $112.6 million, primary earnings
    per share of $0.83 and fully diluted earnings per share of $0.81.

                   LDDS ADJUSTED HISTORICAL INCOME STATEMENT
 
     The following unaudited LDDS Adjusted Historical Income Statement for the
year ended December 31, 1993, illustrates the effect of LDDS' acquisition in
March 1993 of Dial-Net for cash payments of $31.2 million and the issuance of
2.75 million shares of LDDS Common Stock valued at approximately $42.9 million
and the September 15, 1993, three-way merger whereby (i) MCC merged with and
into Resurgens and (ii) LDDS-TN merged with and into Resurgens (previously
defined as the Prior Mergers) for an aggregate purchase price of $1.2 billion.
The LDDS Adjusted Historical Income Statement assumes that the Prior Mergers and
the Dial-Net acquisition, all accounted for as purchase transactions, occurred
at the beginning of the earliest period presented.
 
     At the time of the Prior Mergers, the name of Resurgens, the legal
survivor, was changed to LDDS Communications, Inc. and the separate corporate
existence of LDDS-TN and MCC terminated. For accounting purposes, LDDS-TN is the
survivor because the former shareholders of LDDS-TN acquired the majority
ownership of LDDS.
 
     Upon effectiveness of the Prior Mergers, each share of the outstanding
Class A Common Stock of LDDS-TN was converted into the right to receive 0.9595
shares of LDDS Common Stock. As a result of the consummation of the Prior
Mergers, Metromedia Company ("Metromedia"), the sole stockholder of MCC,
received 2,758,620 shares of the LDDS Common Stock, 10,896,785 shares of LDDS
Series 1 $2.25 Cumulative Senior Perpetual Convertible Preferred Stock having a
liquidation value of $50 per share and a conversion price of $24.9046875 per
share (the "Series 1 Preferred Stock"), warrants to purchase 5,000,400 shares of
the LDDS Common Stock, and $150.0 million in cash. The common stock of Resurgens
was unchanged in the Prior Mergers.
 
     This LDDS Adjusted Historical Income Statement should be read in
conjunction with the historical financial statements of LDDS, MCC and Resurgens
which are incorporated by reference herein.
 
     The LDDS Adjusted Historical Income Statement is presented for comparative
purposes only and is not intended to be indicative of actual results had the
transactions occurred as of the date indicated above nor does it purport to
indicate results which may be attained in the future.

               NOTES TO LDDS ADJUSTED HISTORICAL INCOME STATEMENT
 
1. These columns represent the historical results of operations of Dial-Net, MCC
   and Resurgens, respectively for the period from January 1, 1993 to their
   respective date of acquisition by LDDS.
 
2. These adjustments eliminate the revenues and corresponding line costs
   attributable to the intercompany traffic between MCC and Resurgens.
 
3. This adjustment represents the amortization expense of the excess of cost
   over net tangible assets acquired in the Prior Mergers. The excess purchase
   price over net tangible assets acquired has been recorded based upon an
   estimate of fair values of assets acquired and liabilities assumed. A final
   allocation of the purchase price will be determined when appraisals and other
   studies relating to fixed assets and the utilization of MCC's and Resurgens'
   net operating loss carryforwards ("NOLs") are completed. The excess cost over
   net tangible assets acquired is composed primarily of goodwill which is
   amortized over 40 years using the straight-line method.
 
4. This adjustment represents the amortization of the excess cost over net
   tangible assets acquired in the Dial-Net acquisition. The excess cost over
   net tangible assets acquired is comprised primarily of goodwill and customer
   base which are amortized over 40 years and 10 years, respectively, using the
   straight-line method.
 
5. This adjustment represents the recognition of interest expense on the
   additional borrowings of LDDS to fund the transaction costs of the Prior
   Mergers. The interest expense was calculated based on LDDS' incremental
   borrowing rate of 6.25% at December 31, 1993. A change of  1/8% in the
   assumed rate would affect interest expense by $145,000 for the year ended
   December 31, 1993.
 
6. This adjustment represents the recognition of interest expense on additional
   borrowings of LDDS to fund the acquisition of Dial-Net. The interest expense
   was calculated at LDDS' incremental borrowing rate at December 31, 1993 of
   6.25% per annum. A change of  1/8% in the assumed rate would affect interest
   expense by $8,000 for the year ended December 31, 1993.
 
7. These adjustments represent the tax effect of adjustments due to inclusion of
   the acquired operations. The tax provisions were provided at a combined
   federal and state rate of 39% applied to items impacting taxable income. For
   purposes of the pro forma provision for income taxes for the year ended
   December 31, 1993, loss carryovers utilized by MCC and Resurgens were
   eliminated because utilization of such carryovers after the Prior Mergers
   would have resulted in adjustments to goodwill.
 
8. This adjustment represents the recognition of dividends on the Series 1
   Preferred Stock issued to the MCC shareholder. The Series 1 Preferred Stock
   provides for dividends at the rate of $24.5 million per year.
 
9. Pro forma per share data are based on the number of LDDS common and common
   equivalent shares that would have been outstanding had the acquisitions of
   Dial-Net, MCC and Resurgens occurred on January 1, 1993.

September 1993 of TRT for a cash payment of $1.0 million and the issuance of
10.1 million shares of IDB Common Stock valued at approximately $79.0 million.
The acquisition was accounted for as a purchase. The IDB Adjusted Historical
Income Statement assumes that the TRT acquisition occurred at January 1, 1993.
 
     The IDB Adjusted Historical Income Statement should be read in conjunction
with the historical financial statements of IDB and TRT which are incorporated

               NOTES TO IDB ADJUSTED HISTORICAL INCOME STATEMENT
 
1. IDB reclassified payments to foreign telephone companies to complete calls
   made from the United States by the Company's customers. These payments, which
   previously were classified as direct reductions of transmission services
   revenue, are now classified as cost of sales. Operating income (loss), net
   income (loss) available to common shareholders and the balance sheet are not
   affected. The amount of revenue reported by IDB for the years ended prior to
   December 31, 1993 do not reflect this reclassification because the amounts
   subject to reclassification were not material.
 
2. This column represents the results of operations of TRT for the period from
   January 1, 1993 to the date of acquisition by IDB. The historical revenues
   and cost of sales of TRT have been adjusted to reclassify the payments to
   foreign telephone companies from a direct reduction of revenue to cost of
   sales.
 
3. Restructuring cost savings will accrue from the combination, as a direct
   result of reductions in operating labor force and the elimination of
   duplicative facilities, including reductions in duplicative management,
   administrative locations and selling and administrative functions. The pro
   forma adjustments are based on management estimates of the actual effects of
   restructuring decisions and are presented as if the restructuring were
   completed as of January 1, 1993.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                           OF THE PRO FORMA COMBINING
                              FINANCIAL STATEMENTS
 
     The pro forma combining financial statements reflecting the proposed Merger
of LDDS and IDB, as well as the proposed WilTel Acquisition, have been presented
as required by the rules of the Commission. The required methodology only
assumes the financing of the cash portion of the transactions and related
transaction costs through additional borrowings and the issuance of additional
shares of LDDS Common Stock as a part of the Merger and the WilTel Acquisition,
and the corresponding accounting adjustments to eliminate intercompany
transactions, and to recognize additional interest requirements, amortization
and resulting tax effects. It is the opinion of managements of LDDS, IDB and
WilTel that the pro forma combining financial statements are not necessarily
indicative of the results to be expected in the post merger/acquisition periods.
 
     The pro forma combining income statement for the year ended December 31,
1993 reflects combined pro forma loss applicable to common shareholders of $3.4
million, a decrease in earnings of approximately $105.3 million over the sum of
the three separate companies' amounts. This decrease is primarily attributable
to the additional interest associated with the debt incurred and the
amortization of the additional goodwill recognized in connection with the WilTel
Acquisition. The pro forma combining income statement for the nine months ended
September 30, 1994 also reflects increased interest expense and amortization
expense attributable to higher debt and acquisition related goodwill.
 
     It is believed that the proposed Merger and the WilTel Acquisition would
result in a decrease in operating costs to the consolidated organization through
realization of the economies of scale resulting from network efficiencies and
operational efficiencies. The combination of LDDS, the fourth largest domestic
carrier (based on 1993 revenues), with IDB, the fourth largest international
carrier (based on 1992 revenues), is expected to enhance LDDS's current position
as one of the largest long distance telecommunications companies in the
industry, serving customers domestically and internationally. The WilTel
Acquisition is expected to create additional efficiencies and growth
opportunities for the combined operations of LDDS and IDB. These opportunities
include network efficiencies associated with owning the WilTel nationwide fiber
optic cable network rather than leasing similar capacity from other providers at
a higher cost, and marketing growth opportunities associated with providing more
services to customers. In addition, the increased volume of long distance
traffic is expected to permit the greater use of lower rate fixed-cost or larger
capacity facilities, greater volume discounts on usage sensitive facilities and
greater utilization of owned and leased network capacity. However, no assurance
can be given that LDDS will be able to successfully integrate the operations of
IDB or WilTel or obtain the expected networking and other operating
efficiencies.
 
     The consolidated organization expects to incur approximately $2.6 billion
in additional debt in connection with the proposed WilTel Acquisition. LDDS has
obtained underwritten commitments for unsecured loan facilities aggregating
$3.41 billion to both finance the WilTel Acquisition and to refinance LDDS's
existing credit facilities. The commitments would be funded through Facility A,
a $2.16 billion, six-year reducing revolving credit facility, and Facility B, a
$1.25 billion, two-year term facility. Principal payments under Facility A would
commence in varying quarterly amounts on September 30, 1996 with the final
installment due on December 31, 2000. Facility B would mature in a single
installment on December 31, 1996. Facility A and Facility B would bear interest
at the lower of several interest rate options, payable quarterly, similar to
those in effect under LDDS's existing credit facilities. The facilities would
also be subject to an annual commitment fee not to exceed 0.375% of any
unborrowed portion of Facility A and Facility B.
 
     Borrowings under LDDS's existing and proposed bank credit facilities bear
interest at rates that fluctuate with prevailing short-term interest rates.
Increases in interest rates on these obligations would have an adverse effect
upon LDDS's reported net income and cash flow. In addition, these credit
facilities restrict the payment of dividends and otherwise limit LDDS's
financial flexibility. See "Information Regarding LDDS -- Recent Developments"
for a description of LDDS's proposed credit facilities. Management of LDDS
believes that the combined operations of LDDS, IDB and WilTel would generate
sufficient cash flow to service LDDS's debt under the proposed bank credit
facilities upon consummation of the proposed WilTel Acquisition; however,
 
                                       96
<PAGE>   107
 
economic downturns, increased interest rates and other adverse developments,
including factors beyond LDDS's control, could impair its ability to service its
indebtedness. In addition, the cash flow required to service LDDS's debt would
reduce its liquidity, which in turn may reduce its ability to fund internal
growth, additional acquisitions and capital improvements.
 
     LDDS anticipates it would need to refinance Facility B, which would require
LDDS to seek other financing alternatives such as public or private debt or
equity offerings, or refinancing with the existing or new lenders, although, to
the extent available, Facility A may be used to refinance Facility B; no
assurance can be given that any such refinancing would be available on terms
reasonably acceptable to LDDS. See "Pro Forma Combining Financial Statements."
 
     LDDS has historically utilized cash flow from operations to finance capital
expenditures and a mixture of cash flow, debt and stock to finance acquisitions.
LDDS will continue to analyze acquisitions utilizing primarily equity financing
until the additional leverage from the proposed WilTel Acquisition is reduced.
 
     Management believes future capital expenditures will remain relatively
stable due to the expected lower combined growth rate of the consolidated
company compared to higher individual growth rates of the separate companies.
LDDS is in the process of consolidating switch sites and office space nationwide
and, accordingly, capital expenses for operational expansion should not be
required.
 
     This discussion of pro forma combining financial statements should be read
in conjunction with the historical financial statements and related
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" of LDDS and IDB and the historical financial statements of the
Network Services operations of WilTel included elsewhere or incorporated by
reference herein. See "Available Information" and "Incorporation By Reference."
 
     See "Information Regarding IDB -- Recent Developments" for a description of
certain legal proceedings regarding IDB.
 
                       COMPARATIVE RIGHTS OF SHAREHOLDERS
 
     As a result of the Merger, the stockholders of IDB, whose rights are
currently governed by Delaware law, will become shareholders of LDDS, whose
rights are governed by Georgia law. The following discussion is intended only to
highlight certain differences between the rights of corporate shareholders under
Georgia law and Delaware law generally and specifically with respect to
shareholders of IDB and LDDS. The discussion does not purport to constitute a
detailed comparison of the provisions of Georgia and Delaware law, and IDB
stockholders are referred to those laws for a definitive treatment of the
subject matter.
 
     ELECTION OF DIRECTORS.  Under Delaware law, directors, unless their terms
are staggered, are elected at each annual stockholder meeting. Vacancies on the
board of directors may be filled by the stockholders or directors, unless the
certificate of incorporation or a bylaw provides otherwise. The certificate of
incorporation may authorize the election of certain directors by one or more
classes or series of shares, and the certificate of incorporation, an initial
bylaw or a bylaw adopted by a vote of the stockholders may provide for staggered
terms for the directors. The certificate of incorporation or the bylaws also may
allow the stockholders or the board of directors to fix or change the number of
directors, but a corporation must have at lease one director. IDB's Board of
Directors, which presently consists of six members, has not been established
with staggered terms for directors. Subject to certain restrictions, nominations
to the IDB Board of Directors may be made by either the Board or stockholders,
if delivered to IDB not less than fourteen nor more than sixty days prior to any
stockholders meeting called for the election of directors. Under Delaware law,
stockholders do not have cumulative voting rights unless the certificate of
incorporation so provides. The Restated Certificate of Incorporation of IDB (the
"IDB Charter") does not provide for cumulative voting.
 
     The former stockholders of IDB will have rights under Georgia law in the
election of directors similar to those provided by Delaware law. Directors,
unless their terms are staggered, are elected at each annual shareholder meeting
under Georgia law, and vacancies on the board of directors may be filled by the
shareholders or directors, unless the articles of incorporation or a bylaw
approved by the shareholders provides
 
                                       97
<PAGE>   108
 
otherwise. The articles of incorporation may authorize the election of certain
directors by one or more classes or series of shares. The articles of
incorporation or the bylaws also may allow the shareholders or the board of
directors to fix or change the number of directors. LDDS's Amended and Restated
Articles of Incorporation (the "LDDS Charter") fix the number of members of the
Board of Directors at ten (subject to certain increases in certain instances),
three of which directors are elected by the holders of a majority of the Series
1 Preferred Stock and seven of which (the "Other Directors") are elected by the
holders of LDDS Common Stock and the holders of the Series 2 Preferred Stock,
voting as a single class. In the event the holders of the Series 1 Preferred
Stock own, on a fully diluted basis, less than 2.5% of all outstanding LDDS
Common Stock, also calculated on a fully diluted basis, such holders will have
the right to vote with the holders of LDDS Common Stock and the Series 2
Preferred Stock in the election of the Other Directors. Subject to certain
restrictions, nominations to the LDDS Board of Directors may be made by either
the Board or shareholders, if delivered to LDDS not later than ninety days prior
to the anniversary date of the immediately preceding annual meeting of LDDS
shareholders. Under Georgia law, shareholders do not have cumulative voting
rights for the election of directors unless the articles of incorporation so
provide. The LDDS Charter does not provide for cumulative voting.
 
     REMOVAL OF DIRECTORS.  Under Delaware law, directors of a corporation may
be removed, with or without cause, by the holders of a majority of the shares
entitled to vote at an election. The IDB Charter provides, however, that
directors may only be removed for cause and only by the affirmative vote of at
least 75% of the voting power of all outstanding shares of IDB's voting stock,
provided that if a majority of the Continuing Directors (see "-- Business
Combination Restrictions") approves the removal of a director for cause, the
only stockholder vote required would be that of a majority of IDB's voting
stock.
 
     Georgia law provides that, unless director terms are staggered, directors
may be removed with or without cause by a majority of the votes entitled to be
cast, unless the articles of incorporation or a bylaw adopted by the
shareholders provides that directors may be removed only for cause, provided,
however, that if a director is elected by a particular voting group of
shareholders, that director may only be removed by the vote of that voting
group. Thus, the affirmative vote of a majority of the holders of the Series 1
Preferred Stock would be required to remove any of the three directors elected
by that class of shareholders, and the affirmative vote of a majority of the
votes cast by the holders of the LDDS Common Stock and the Series 2 Preferred,
voting as a group, would be required to remove any of the other directors. As
stated above with respect to the election of directors, in the event the holders
of the Series 1 Preferred Stock own, on a fully diluted basis, less than 2.5% of
all outstanding LDDS Common Stock, also calculated on a fully diluted basis,
such holders will be entitled to vote with the holders of LDDS Common Stock and
the Series 2 Preferred Stock, voting as a group, on the removal of any of the
Other Directors.
 
     AMENDMENTS TO CHARTER.  Under Delaware law, unless a higher vote is
required in the certificate of incorporation, an amendment to the certificate of
incorporation of a corporation may be approved by a majority of the outstanding
shares entitled to vote upon the proposed amendment. The IDB Charter requires
the affirmative vote of 75% of the outstanding shares with respect to certain
amendments, including certain provisions related to the issuance and terms of
preferred stock, the power of the directors and the stockholders to amend the
Bylaws of IDB, limitations on director liability, composition of the board of
directors, stockholder action and special meetings, business combination
restrictions and stockholder appraisal rights.
 
     Georgia law provides that, unless a corporation's articles of incorporation
provide otherwise, directors may only make certain relatively technical
amendments to a corporation's articles of incorporation. Otherwise, only the
affirmative vote of a majority of the votes entitled to be cast on the amendment
by each voting group entitled to vote on the amendment, may amend a Georgia
corporation's articles of incorporation; provided, however, that the LDDS
Charter provides that no amendment may be made to the LDDS Charter that would
adversely affect certain rights, preferences and relative priority of the
holders of LDDS Preferred Stock unless such amendment is approved by the
affirmative vote of at least 66 2/3% of the outstanding shares of the affected
class of Preferred Stock.
 
     AMENDMENTS TO BYLAWS.  Delaware law provides that a corporation's bylaws
may be amended by that corporation's stockholders, or, if so provided in the
corporation's certificate of incorporation, the power to
 
                                       98
<PAGE>   109
 
amend the corporation's bylaws may also be conferred on the corporation's
directors. The IDB Charter provides that IDB's directors may amend IDB's Bylaws.
In addition, IDB's stockholders may amend IDB's Bylaws by the affirmative vote
of 75% of all outstanding voting stock, unless the amendment to the Bylaws is
proposed by an Interested Stockholder (see "-- Business Combination
Restrictions"), in which case the amendment must be approved either (a) by the
affirmative vote of a majority of all outstanding voting stock, excluding voting
stock held by the Interested Stockholder (and its affiliates or associates), or
(b) if approved by a majority of the Continuing Directors (see "-- Business
Combination Restrictions"), by the affirmative vote of a majority of all
outstanding voting stock.
 
     Georgia law provides that, unless a corporation's articles of
incorporation, applicable law or a particular bylaw approved by the
corporation's shareholders provides otherwise, either the corporation's
directors or its shareholders may amend that corporation's bylaws. The LDDS
Bylaws do not permit the directors of LDDS to amend the Bylaws to increase the
number of directors if certain events have occurred that permit the holders of
the Series 1 Preferred Stock to elect one or more directors.
 
     SPECIAL MEETINGS OF SHAREHOLDERS.  Delaware law provides that special
meetings of the stockholders of a corporation may be called by the corporation's
board of directors or by such other persons as may be authorized in the
corporation's certificate of incorporation or bylaws. IDB's Charter provides
that special meetings of IDB's stockholders may only be called by the Board of
Directors of IDB, the Chairman of the Board or the President.
 
     Georgia law provides that special meetings of shareholders of a corporation
may be called by the corporation's board of directors, by the holders of such
percentage of the corporation's voting stock as is designated in the
corporation's articles of incorporation or bylaws, or by such other persons as
may be authorized in the corporation's articles of incorporation or bylaws.
LDDS's Bylaws provide that a special meeting may be called by the Board of
Directors of LDDS, the President of LDDS or the holders of not less than 40% of
all the votes entitled to be cast on the issue proposed to be considered at the
proposed special meeting.
 
     VOTE ON EXTRAORDINARY CORPORATE TRANSACTIONS.  Delaware law provides that,
unless otherwise specified in a corporation's certificate of incorporation or
unless the provisions of Delaware law relating to "business combinations"
discussed below are applicable, a sale or other disposition of all or
substantially all of the corporation's assets or a merger or consolidation of
the corporation with another corporation or a dissolution of the corporation
requires the affirmative vote of the Board of Directors (except in certain
limited circumstances) plus, with certain exceptions, the affirmative vote of a
majority of the outstanding stock entitled to vote thereon. Except as provided
with respect to the "business combination" provisions of the IDB Charter, the
foregoing provisions apply to IDB and its stockholders.
 
     Georgia law is similar to Delaware law in that, except as described below
with respect to "business combinations," a sale or other disposition of all or
substantially all of the corporation's assets or a merger of the corporation
with and into another corporation or a share exchange involving one or more
classes or series of the corporation's shares or a dissolution of the
corporation requires the affirmative vote of the Board of Directors (except in
certain limited circumstances) plus, with certain exceptions, the affirmative
vote of a majority of all shares of stock entitled to vote thereon. The LDDS
Charter does not alter this provision of Georgia law, except that the
affirmative vote of 66 2/3% of the Series 2 Preferred Stock is required, with
certain exceptions, to authorize the voluntary liquidation, dissolution, winding
up, recapitalization or reorganization of LDDS or the consolidation or merger of
LDDS with and into another corporation or the sale or distribution to another
person of all or substantially all of the assets of LDDS.
 
     DIVIDENDS.  Subject to any restrictions contained in a corporation's
certificate of incorporation, Delaware law generally provides that a corporation
may declare and pay dividends out of a surplus (defined as the excess, if any,
of net assets over capital) or, when no surplus exists, out of net profits for
the fiscal year in which the dividend is declared and/or the preceding fiscal
year. Dividends may not be paid out of net profits if the capital of the
corporation is less than the amount of capital represented by the issued and
outstanding stock of all classes having a preference upon the distribution of
assets. The IDB Charter contains no additional
 
                                       99
<PAGE>   110
 
restrictions on the declaration or payment of dividends. None of IDB's existing
debt agreements restrict its ability to pay dividends on IDB Common Stock.
 
     Georgia law provides that, subject to any restrictions contained in a
corporation's articles of incorporation, the directors of a corporation may
authorize the payment of dividends to that corporation's shareholders, provided
that no such dividend may be paid if, after giving effect to such payment, (a)
the corporation would be unable to pay its debts as they come due in the
ordinary course of business or (b) the corporation's total assets would be less
than the sum of its total liabilities plus any preferential liquidation amounts
payable to shareholders whose preferential rights on dissolution are superior to
those of the shareholders receiving the dividend. Other than the preferential
rights of the holders of LDDS Preferred Stock with respect to dividends (see
"-- Effect of Outstanding Preferred Stock" below), the LDDS Charter contains no
additional restrictions on the declaration or payment of dividends; however,
LDDS's existing and proposed credit facilities prohibit the payment of cash
dividends on LDDS Common Stock without the prior consent of the lenders.
 
     EFFECT OF OUTSTANDING PREFERRED STOCK.  By becoming holders of LDDS Common
Stock, the former holders of IDB Common Stock will become subject to the rights
and preferences of the holders of LDDS Preferred Stock. In addition to the
special rights and preferences described above, such rights and preferences
include preferential, cumulative dividends, preferential payments upon
dissolution or liquidation of LDDS, the right to expand the LDDS Board of
Directors and elect additional LDDS directors in the event certain Preferred
Stock dividend payments are not made and in other specified events, the right to
convert shares of Preferred Stock into shares of Common Stock, and, with respect
to the Series 2 Preferred Stock, the right to have such Preferred Stock redeemed
in the event of a Change in Control (as defined in the LDDS Charter). See the
description of LDDS Preferred Stock contained under the captions "Proposals No.
1 and 2 -- The Proposed Mergers -- Description of the Series 1 Preferred Stock,"
"-- Description of the Series 2 Preferred Stock," "Information Regarding
Resurgens -- Description of Resurgens Capital Stock" and "-- Amendments to
Resurgens' Restated Articles of Incorporation -- LDDS Merger Agreement" in the
1993 Joint Proxy Statement/Prospectus, which are hereby incorporated herein by
reference.
 
     APPRAISAL RIGHTS OF DISSENTING SHAREHOLDERS.  Under Delaware law, a
stockholder of a Delaware corporation is generally entitled to demand appraisal
of and obtain payment of the fair value of his or her shares in the event of any
plan of merger or consolidation to which the corporation, the shares of which he
holds, is a party. However, this right to demand appraisal does not apply to
stockholders if: (1) they are stockholders of a surviving corporation and if a
vote of the stockholders of such corporation is not necessary to authorize the
merger or consolidation; (2) the shares held by the stockholders are of a class
or series registered on the New York Stock Exchange or the American Stock
Exchange, designated as a national market system security on an interdealer
quotation system by the National Association of Securities Dealers, Inc. or are
held of record by more than 2,000 stockholders on the date set to determine the
stockholders entitled to vote on the merger or consolidation. Notwithstanding
the above, appraisal rights are available for the shares of any class or series
of stock of a Delaware corporation if the holders thereof are required by the
terms of an agreement of merger or consolidation to accept for their stock
anything except: (i) shares of stock of the corporation surviving or resulting
from the merger or consolidation; (ii) shares of stock of any other corporation
which at the effective date of the merger or consolidation will be listed on the
New York Stock Exchange or the American Stock Exchange, designated as a national
market system security on an interdealer quotation system by the National
Association of Securities Dealers, Inc. or held of record by more than 2,000
stockholders; (iii) cash in lieu of fractional shares of the corporations
described in (i) and (ii); or (iv) any combination of the shares of stock and
cash in lieu of fractional shares described in (i), (ii) and (iii).
 
     A Delaware corporation may provide in its certificate of incorporation that
appraisal rights shall be available for the shares of any class or series of its
stock as the result of an amendment to its certificate of incorporation, any
merger or consolidation to which the corporation is a party, or a sale of all or
substantially all of the assets of the corporation.
 
     IDB stockholders are not entitled to appraisal rights in connection with
the Merger, because: (i) shares of IDB Common Stock were, at the record date
fixed to determine the stockholders entitled to receive notice of
 
                                       100
<PAGE>   111
 
and to vote at the Special Meeting, designated as a Nasdaq National Market
security; (ii) IDB stockholders will not be required to accept anything in
exchange for their IDB Shares other than LDDS Shares (i.e., shares of stock of a
corporation designated as a Nasdaq National Market security) and cash in lieu of
fractional shares of such stock; and (iii) the IDB Charter does not otherwise
provide IDB stockholders with dissenters' or appraisal rights applicable to the
Merger. See "Dissenter's Rights."
 
     Georgia law provides shareholders with dissenters' rights of appraisal
similar to Delaware law. If shareholders are permitted to dissent and dissent
from mergers, share exchanges, sales or exchanges of all or substantially all of
the corporation's assets, or an amendment to the articles of incorporation that
materially and adversely affects rights in respect of a dissenter's shares, such
shareholders are entitled to have their shares appraised. However, unless the
corporation's articles of incorporation otherwise provide, dissenters' rights
are not available: (i) to holders of shares of any class of shares not entitled
to vote on the merger, share exchange or sale or exchange of all or
substantially all of a corporation's assets; (ii) in a sale or exchange of all
or substantially all of the property of the corporation pursuant to court order;
(iii) in a sale for cash, where all or substantially all of the net proceeds
will be distributed to the shareholders within one year; or (iv) to holders of
shares which at the record date were either listed on a national securities
exchange or held of record by more than 2,000 shareholders, unless: (a) in the
case of a plan of merger or share exchange, the holders of shares of the class
or series are required under the plan of merger or share exchange to accept for
their shares anything except shares of the surviving corporation or a publicly
held corporation which at the effective date of the merger or share exchange are
either listed on a national securities exchange or held of record by more than
2,000 shareholders, except for scrip or cash payments in lieu of fractional
shares; or (b) the articles of incorporation or a resolution of the board of
directors approving the transaction provides otherwise. LDDS shareholders are
not entitled to dissenters' or appraisal rights in connection with the Merger.
See "Dissenter's Rights."
 
     INDEMNIFICATION AND LIMITATION OF LIABILITY OF DIRECTORS AND
OFFICERS.  Delaware law permits a corporation to adopt a provision in its
certificate of incorporation eliminating or limiting the personal liability of a
director to the corporation or its stockholders for monetary damages for breach
of fiduciary duty as a director, except that such provision shall not limit the
liability of a director for: (i) any breach of the director's duty of loyalty to
the corporation or its stockholders, (ii) acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii)
liability under Section 174 of the Delaware General Corporation Law for unlawful
payment of dividends or stock purchases or redemptions, or (iv) any transaction
from which the director derived an improper personal benefit. The IDB Charter
limits the personal liability of IDB's directors for monetary damages to the
fullest extent permissible under applicable law.
 
     Under Delaware law, a corporation may indemnify any person made a party or
threatened to be made a party to any type of proceeding (other than an action by
or in the right of the corporation) because he is or was an officer, director,
employee or agent of the corporation, or was serving at the request of the
corporation as a director, officer, employee or agent of another corporation or
entity, against expenses, judgments, fines and amounts paid in settlement
actually and reasonably incurred in connection with such proceeding: (1) if he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the corporation; or (2) in the case of a
criminal proceeding, he had no reasonable cause to believe that his conduct was
unlawful. A corporation may indemnify any person made a party or threatened to
be made a party to any threatened, pending or completed action or suit brought
by or in the right of the corporation because he was an officer, director,
employee or agent of the corporation, or is or was serving at the request of the
corporation as a director, officer, employee or agent of another corporation or
other entity, against expenses actually and reasonably incurred in connection
with such action or suit if he acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the corporation,
except that there may be no such indemnification if the person is found liable
to the corporation unless, in such a case, the court determines the person is
entitled thereto. A corporation must indemnify a director, officer, employee or
agent against expenses actually and reasonably incurred by him who successfully
defends himself in a proceeding to which he was a party because he was a
director, officer, employee or agent of the corporation. Expenses incurred by an
officer or director (or other employees or agents as deemed appropriate by the
Board of Directors) in defending a civil or criminal proceeding may be paid by
the corporation in advance of the final
 
                                       101
<PAGE>   112
 
disposition of such proceeding upon receipt of an undertaking by or on behalf of
such director or officer to repay such amount if it shall ultimately be
determined that he is not entitled to be indemnified by the corporation. The
Delaware law indemnification and expense advancement provisions are not
exclusive of any other rights which may be granted by the bylaws, a vote of
stockholders or disinterested directors, agreement or otherwise. The IDB Bylaws
provide for the indemnification of and the advancement of defense costs to IDB's
directors, officers, employees and agents to the extent not prohibited by
Delaware law. In addition, IDB has entered into indemnification agreements with
each of its directors and executive officers to provide for indemnification,
provided the indemnitee acted in good faith and in a manner reasonably believed
to be in or not opposed to the best interests of the company and, with respect
to any criminal action or proceedings, had no reasonable cause to believe his
conduct was unlawful; and provided further, indemnification is not required with
respect to conduct that was knowingly fraudulent or dishonest, as determined in
a final judgment. In addition, the agreements require the advancement of
expenses (including attorneys' fees), subject to an undertaking to repay such
amount if ultimately determined not to be entitled to indemnification. Under the
Merger Agreement, LDDS has agreed to provide indemnification to IDB's officers
and directors in certain circumstances. See "Plan of Merger -- Interests of
Certain Persons in the Merger -- Indemnification."
 
     Georgia law permits corporations to adopt a provision in their articles of
incorporation eliminating or limiting the personal liability of a director to
the corporation or its shareholders for monetary damages for breach of the
director's duty of care or other duties as directors. Georgia law does not
permit the elimination or limitation of monetary liability in the event of (i)
misappropriation of corporate business opportunities; (ii) intentional
misconduct or knowing violation of the law; (iii) unlawful distributions; or
(iv) improper personal benefit. The LDDS Charter limits the personal liability
of directors for monetary damages to the fullest extent permissible under
applicable law.
 
     Unless otherwise provided by the articles of incorporation, or a bylaw,
contract or resolution approved by a majority of the shareholders, Georgia law
permits a corporation to indemnify a person made a party to a proceeding as a
result of his status as a director if such person believed, in good faith, that
his actions were in or not opposed to the best interests of the corporation and,
in the case of a criminal proceeding, such director had no reasonable grounds to
believe his actions were unlawful. The determination of whether the director has
met the requisite standard of conduct for indemnification may be made by (i) a
majority vote of a quorum consisting of directors not at that time parties to
the suit; (ii) a duly designated committee of directors; (iii) duly selected
special legal counsel; or (iv) by the shareholders, excluding shares owned by or
voted under the control of directors who are at that time parties to the suit. A
director may not be indemnified for liability incurred in a suit by or in the
right of the corporation in which he was adjudged liable to the corporation or
if such director was adjudged liable for improperly receiving a personal
benefit. Under Georgia law, officers of a corporation have similar statutory
rights of indemnification as directors, unless the articles of incorporation
provide otherwise. A corporation's authority to indemnify officers, unlike
directors, is restricted only by public policy. A person who is both an officer
and a director is treated, for indemnification purposes, as a director. The LDDS
Charter and Bylaws authorize indemnification of its officers and directors to
the full extent permitted by Georgia law.
 
     PREEMPTIVE RIGHTS.  Neither Delaware nor Georgia law provides for
preemptive rights to acquire a corporation's unissued stock. However, such right
may be expressly granted to the shareholders in a corporation's certificate or
articles of incorporation. Neither the IDB Charter nor the LDDS Charter provides
for preemptive rights.
 
     SPECIAL REDEMPTION PROVISIONS.  The LDDS Charter contains provisions
permitting LDDS to redeem shares of its capital stock from certain foreign
shareholders in order to enable it to continue to hold certain common carrier
radio licenses. These provisions are intended to cause LDDS to remain in
compliance with the Communications Act and the regulations of the FCC
promulgated thereunder.
 
     Under these provisions, at such time as the percentage of capital stock
owned by foreign shareholders or certain affiliates thereof exceeds 20%, LDDS
has the right to redeem the "excess shares" held by such persons at the fair
market value thereof. Following any determination that such excess shares exist,
such excess shares shall not be deemed outstanding for purposes of determining
the vote required on any matter brought to the
 
                                       102
<PAGE>   113
 
attention of the shareholders of LDDS and such excess shares shall have no right
to receive any dividends or other distributions, including distributions in
liquidation. If such shares are traded on a national securities exchange or in
the over-the-counter market, such fair market value is the average closing price
for the 45 trading days immediately preceding the date of redemption. If such
shares are not so traded, such fair market value shall be established by the
Board of Directors of LDDS. In the event there is a foreign shareholder who
acquired shares within 120 days of the date of redemption, however, the
redemption price shall not exceed the price per share paid by such shareholder.
At least 30 days' notice of redemption must be given, and the redemption price
may be paid in cash, securities or any combination thereof. LDDS may require
confirmation of citizenship from any record or beneficial owner of shares of its
capital stock, and from any transferee thereof, as a condition to the
registration or transfer of those shares.
 
     Because IDB does not hold any FCC common carrier transmission licenses,
IDB's Charter does not contain comparable provisions. See "Plan of
Merger -- Interests of Certain Persons in the Merger -- Acquisition of SCI."
 
     BUSINESS COMBINATION RESTRICTIONS.  In general, Delaware law prevents an
"Interested Stockholder" (defined generally as a person with 15% or more of a
corporation's outstanding voting stock, with the exception of any person who
owned and has continued to own shares in excess of the 15% limitation since
December 23, 1987) from engaging in a "Business Combination" with a Delaware
corporation for three years following the date such person became an Interested
Stockholder. The term "Business Combination" includes mergers or consolidations
with an Interested Stockholder and certain other transactions with an Interested
Stockholder, including, without limitation: (i) any sale, lease, exchange,
mortgage, pledge, transfer or other disposition to or with the Interested
Stockholder of assets (except proportionately as a stockholder of the
corporation) having an aggregate market value equal to 10% or more of the
aggregate market value of all assets of the corporation determined on a
consolidated basis or the aggregate market value of all the outstanding stock of
the corporation; (ii) any transaction which results in the issuance or transfer
by the corporation or by certain subsidiaries thereof of stock of the
corporation or such subsidiary to the Interested Stockholder, except pursuant to
a transaction which, in general, effects a pro rata distribution to all
stockholders of the corporation; (iii) any transaction involving the corporation
or certain subsidiaries thereof which has the effect, directly or indirectly, of
increasing the proportionate share of the shares of any class or series, or
securities convertible into shares of the corporation or any subsidiary which is
owned directly or indirectly by the Interested Stockholder (except as a result
of immaterial changes due to fractional share adjustments or as a result of any
purchase or redemption of any shares not caused by the Interested Stockholder);
or (iv) any receipt by the Interested Stockholder of the benefit (except
proportionately as a stockholder of such corporation) of any loans, advances,
guarantees, pledges, or other financial benefits provided by or through the
corporation or certain subsidiaries.
 
     The three-year moratorium may be avoided if: (i) before such person became
an Interested Stockholder, the Board of Directors of the corporation approved
either the Business Combination or the transaction in which the Interested
Stockholder became an Interested Stockholder; or (ii) upon consummation of the
transaction which resulted in the stockholder becoming an Interested
Stockholder, the stockholder owned at least 85% of the voting stock of the
corporation outstanding at the time the transaction commenced (excluding shares
held by directors who are also officers of the corporation and by employee stock
ownership plans that do not provide employees with the right to determine
confidentially whether shares held subject to the plan will be tendered in a
tender or exchange offer); or (iii) on or following the date on which such
person became an Interested Stockholder, the Business Combination is approved by
the Board of Directors of the corporation and authorized at an annual or special
meeting of stockholders (not by written consent) by the affirmative vote of the
stockholders of at least 66 2/3% of the outstanding voting stock of the
corporation not owned by the Interested Stockholder.
 
     The Business Combination restrictions described above do not apply if,
among other things: (i) the corporation's original certificate of incorporation
contains a provision expressly electing not to be governed by the statute; (ii)
the holders of a majority of the voting stock of the corporation approve an
amendment to its certificate of incorporation or bylaws expressly electing not
to be governed by the statute (effective twelve (12) months after the
amendment's adoption), which amendment shall not be applicable to any business
 
                                       103
<PAGE>   114
 
combination with a person who was an Interested Stockholder at or prior to the
time of the amendment; or (iii) the corporation does not have a class of voting
stock that is (a) listed on a national securities exchange, (b) authorized for
quotation on Nasdaq or a similar quotation system; or (c) held of record by more
than 2,000 stockholders. The statute also does not apply to certain Business
Combinations with an Interested Stockholder when such combination is proposed
after the public announcement of, and before the consummation or abandonment of,
a merger or consolidation, a sale of 50% or more of the aggregate market value
of the assets of the corporation on a consolidated basis or the aggregate market
value of all outstanding shares of the corporation, or a tender offer for 50% or
more of the outstanding voting shares of the corporation, if the triggering
transaction is with or by a person who either was not an Interested Stockholder
during the previous three years or who became an Interested Stockholder with
Board of Director approval, and if the transaction is approved or not opposed by
a majority of the current directors who were also directors prior to any person
becoming an Interested Stockholder during the previous three years.
 
     IDB's Charter provides that certain business combinations involving IDB and
a person owning 5% or more of the outstanding voting stock of IDB (an "IDB
Interested Stockholder") may be effected only if approved by the holders of not
less than 75% of the voting power of all outstanding shares of IDB's voting
stock, voting as a single class, provided that such 75% includes a majority of
the voting stock held by persons other than IDB Interested Stockholders who are
parties to a proposed business combination. Such an affirmative vote is not
required, however, for any business combination in which either (i) a majority
of the Continuing Directors (as hereinafter defined) have approved such business
combination and such business combination has been approved by the affirmative
vote of IDB's stockholders required by law, if any, or (ii) the business
combination has been approved by the affirmative vote of the holders of a
majority of the voting power of IDB's outstanding voting stock, voting as a
single class, and the amount and form of consideration received by IDB's
stockholders in such business combination equals or exceeds certain minimum
criteria set forth in IDB's Charter. A member of IDB's Board of Directors is
considered a Continuing Director if (a) such director was originally elected to
the Board of Directors on the incorporation of IDB, (b) such Director is not an
IDB Interested Stockholder (or an affiliate or associate of an IDB Interested
Stockholder) and was a member of the Board of Directors prior to the time that
an IDB Interested Stockholder became an IDB Interested Stockholder or (c) such
Director is elected or nominated to join the Board of Directors by a majority of
the Continuing Directors, unless a majority of the Continuing Directors
determine to designate such person as not a Continuing Director. All of IDB's
current directors are Continuing Directors, as defined in IDB's Charter.
 
     For a description of certain other aspects of IDB's Charter that may have
"anti-takeover" effects, see "Risk Factors -- Factors Concerning
IDB -- Anti-Takeover Provisions."
 
     Under Georgia law, Georgia corporations may adopt a provision in their
bylaws requiring that "Business Combinations" be approved by a special vote of
the board of directors and/or the shareholders unless certain fair pricing
criteria are met. Georgia corporations may also adopt a provision in their
articles of incorporation or bylaws which requires that "Business Combinations"
with "Interested Shareholders" be approved by a super majority vote. These
provisions, neither of which has been adopted by LDDS, are described below. Also
described below is the business combination restriction contained in the LDDS
Charter.
 
     Georgia's "fair price" statute authorizes a corporation to adopt a bylaw
provision which requires special approval by the board of directors and/or
shareholders for "Business Combinations" unless certain "fair price" criteria
are met. Generally, for purposes of this statute, "Business Combination" is
defined to include mergers, sales of assets out of the ordinary course of
business, liquidations, and certain issuances of securities involving the
corporation and any "Interested Shareholder." For purposes of this statute, an
"Interested Shareholder" is defined as a person or entity that is the beneficial
owner of 10% or more of the outstanding shares of the corporation's voting
stock, or a person or entity that is an affiliate of the corporation and, at any
time within the two-year period immediately prior to the date in question, was
the beneficial owner of 10% or more of the then outstanding shares of the
corporation's voting stock. A Business Combination with an Interested
Shareholder must meet one of three criteria: (i) the transaction must be
unanimously approved by the "Continuing Directors" (directors who served as
directors immediately prior to the date the Interested Shareholder first became
an Interested Shareholder and who are not affiliates or associates of the
Interested Shareholder),
 
                                       104
<PAGE>   115
 
provided that the Continuing Directors constitute at least three members of the
board of directors at the time of such approval; (ii) the transaction must be
recommended by at least two-thirds of the Continuing Directors and approved by a
majority of the votes entitled to be cast by holders of voting shares, excluding
shares held by the Interested Shareholder; or (iii) the terms of the transaction
must meet fair pricing criteria and certain other tests intended to assure that
all shareholders receive a fair price and equivalent consideration for their
shares regardless of when they sell to the acquiring party.
 
     Georgia's "business combination" statute authorizes a corporation to adopt
a bylaw provision which prohibits "Business Combinations" with "Interested
Shareholders" occurring within five years of the date a person first becomes an
Interested Shareholder, unless special approval of the transaction is obtained.
For purposes of this statute, "Business Combination" is defined to include
mergers, sales of 10% or more of the corporation's net assets, and certain
issuances of securities involving the corporation and any "Interested
Shareholder." "Interested Shareholder" has the same definition as under the
Georgia "fair price" statute. Any Business Combination with an Interested
Shareholder within five years of the date such person first became an Interested
Shareholder requires approval in one of three ways: (i) prior to becoming an
Interested Shareholder, the corporation's board of directors must have approved
the Business Combination or the transaction which resulted in the shareholder
becoming an Interested Shareholder; (ii) the Interested Shareholder acquires at
least 90% of the outstanding voting stock of the corporation (other than shares
owned by officers, directors and their affiliates and associates) in the same
transaction in which such person becomes an Interested Shareholder; or (iii)
subsequent to becoming an Interested Shareholder, such person acquires
additional shares resulting in ownership of at least 90% of the outstanding
shares (other than shares owned by officers, directors and their affiliates and
associates), and obtains the approval of the Business Combination by the holders
of a majority of the remaining shares.
 
     LDDS's Charter contains a provision that requires the approval by the
holders of at least 70% of the voting power of the outstanding shares of any
class of stock of LDDS entitled to vote generally in the election of directors
as a condition for Business Transactions (defined below) involving LDDS and a
Related Person (defined below) or in which a Related Person has an interest,
unless (a) the Business Transaction is approved by at least a majority of LDDS's
Continuing Directors (defined below) then serving on the Board of Directors, but
if the votes of such Continuing Directors would have been insufficient to
constitute an act of the Board of Directors, then such transaction must have
been approved by the unanimous vote of such Continuing Directors so long as
there were at least three such Continuing Directors serving on the Board of
Directors at the time of such unanimous vote, provided that no such Continuing
Director is a Related Person who has an interest in the Business Transaction
(other than a proportionate interest as a shareholder of LDDS), or (b) certain
minimum price and procedural requirements are met. A "Business Transaction" is
defined to mean: (i) any merger, share exchange or consolidation involving LDDS
or any of its subsidiaries; (ii) any sale, lease, exchange, transfer or other
disposition by LDDS or any of its subsidiaries of more than 20% of its assets;
(iii) any sale, lease, exchange, transfer or disposition of more than 20% of the
assets of an entity to LDDS or a subsidiary of LDDS; (iv) the issuance, sale,
exchange, transfer or other disposition by LDDS or a subsidiary of LDDS of any
securities of LDDS or any subsidiary in exchange for cash, securities or other
properties having an aggregate fair market value of $15.0 million or more; (v)
any merger, share exchange or consolidation between LDDS and any subsidiary of
LDDS in which LDDS is not the survivor and the charter of the surviving
corporation does not contain provisions similar to this provision; (vi) any
recapitalization or reorganization of LDDS or reclassification of its securities
which would have the effect of increasing the voting power of a Related Person;
(vii) any liquidation, spin off, split off, split up or dissolution of LDDS; and
(viii) any agreement, contract or other arrangement providing for any of the
Business Transactions defined or having a similar purpose or effect. A "Related
Person" is defined to mean a beneficial owner which, together with its
Affiliates and Associates (defined below), beneficially own 10% or more of
LDDS's outstanding voting stock or who had such level of beneficial ownership:
(a) at the time of entering into the definitive agreement providing for the
Business Transaction; (b) at the time of adoption by the Board of Directors of a
resolution approving such transaction; or (c) as of the record date for the
determination of shareholders entitled to vote on or consent to the Business
Transaction. A "Continuing Director" is a director of LDDS who either was a
member of the Board of Directors on September 15, 1993, or who became a director
of LDDS subsequent to such date and whose election, or nomination for election
by the shareholders, was approved by at least a
 
                                       105
<PAGE>   116
 
majority of the Continuing Directors then on the Board of Directors. If the
votes of such Continuing Directors would have been insufficient to constitute an
act of the Board of Directors, then such election or nomination must have been
approved by the unanimous vote of the Continuing Directors so long as there were
at least three such Continuing Directors on the Board of Directors at the time
of such unanimous vote. An "Affiliate" is defined to mean a person that
directly, or indirectly through one or more intermediaries, controls, or is
controlled by, or is under common control with, such specified person. An
"Associate" is defined to mean: (a) any corporation, partnership or other
organization of which such specified person is an officer or partner; (b) any
trust or other estate in which such specified person has a substantial
beneficial interest or as to which such specified person serves as trustee or in
a similar fiduciary capacity; (c) any relative or spouse of such specified
person, or any relative of such spouse, who has the same home as such specified
person or who is a director or officer of LDDS or any of its subsidiaries; and
(d) any person who is a director, officer or partner of such specified person or
of any corporation (other than LDDS or any wholly owned subsidiary of LDDS),
partnership or other entity which is an Affiliate of such specified person.

"anti-takeover" effects, see "Risk Factors -- Factors Concerning
LDDS -- Anti-Takeover Provisions."
 
               ITEM 2.  APPROVAL OF THE LDDS COMMUNICATIONS, INC.
                      1995 SPECIAL PERFORMANCE BONUS PLAN
 
     Under recent amendments to the Internal Revenue Code of 1986, as amended
(the "Code"), adding Section 162(m) to the Code and the proposed rules and
regulations issued thereunder ("Section 162(m)"), LDDS, for federal income tax
purposes, generally may not deduct certain employee compensation that would
otherwise be deductible to the extent that such compensation exceeds $1,000,000
for any such individual in any fiscal year. However, compensation that is
"performance-based" (as defined in Section 162(m)) is not subject to the
deductibility limitations.
 
     In 1994, the Compensation and Stock Option Committee of LDDS's Board of
Directors determined to develop a special performance bonus plan for the Chief
Executive Officer with respect to fiscal year 1995. Accordingly, the Committee
has approved the adoption of the 1995 Special Performance Bonus Plan (the "1995
Plan") for the Chief Executive Officer of LDDS, and has recommended that the
1995 Plan be submitted to the shareholders for adoption. The 1995 Plan is
designed to qualify as a "performance-based" compensation plan for purposes of
Section 162(m) and would be in addition to any other bonus payable to the Chief
Executive Officer.
 
     The cash bonus under the 1995 Plan is predicated on the achievement by LDDS
of one or more quantitative performance goals. Subject to attainment of the
specified performance goal(s) and the limitation with respect to the maximum
bonus payable under the 1995 Plan, any actual cash award under the 1995 Plan
will be made based on the Committee's subjective assessment of the contributions
of the Chief Executive Officer. The Committee believes the 1995 Plan will enable
LDDS to continue to motivate, reward and retain the Chief Executive Officer to
promote the financial performance and growth of LDDS, without limiting LDDS's
ability to deduct compensation awarded under the 1995 Plan for federal income
tax purposes.
 
     A copy of the 1995 Plan is attached as Appendix E to this Joint Proxy
Statement/Prospectus. Following is a description of the material features of the
1995 Plan, which is qualified in its entirety by reference to Appendix E.
 
     ADMINISTRATION; ELIGIBILITY.  The 1995 Plan will be administered by the
Compensation and Stock Option Committee, such other committee as the Board of
Directors may designate, or a subcommittee of any such committee as may be
designated by such committee (the "Plan Committee"). Pursuant to the
requirements of Section 162(m), the Plan Committee must consist of at least two
directors and all members must be "outside directors" (as defined in Section
162(m)). The decisions of the Plan Committee are subject to the approval of the
Board of Directors. The Compensation and Stock Option Committee, currently
comprised of Stiles A. Kellett, Jr. (Chairman), Danny M. Dunnaway and Silvia
Kessel, will administer the 1995 Plan. The Chief Executive Officer is the only
employee eligible to participate in the 1995 Plan (the "Participant").

     DETERMINATION OF BONUS.  The award of a bonus under the 1995 Plan with
respect to fiscal year 1995 is conditioned on the achievement by LDDS of one or
more specific performance goals. Under the 1995 Plan, the Plan Committee is
authorized to establish one or more particular performance goals and the maximum
bonus, which is not to exceed $1,000,000. The Plan Committee will convene as and
when appropriate to determine whether the performance target has been satisfied
as derived from LDDS's regularly prepared financial statements. Any bonus
awarded under the 1995 Plan is payable in cash. The Committee believes that the
award of a bonus based on the performance criteria provided in the 1995 Plan
will further LDDS's philosophy that executive compensation be aligned with the
financial interests of LDDS's shareholders.
 
     Subject to the attainment of the performance goal established by the Plan
Committee, the Plan Committee has discretion to determine the specific amount of
any award made under the 1995 Plan for the Participant, up to the maximum bonus
established for the Participant.
 
     The Plan Committee has established a specific performance goal with respect
to 1995 based on the attainment by LDDS of specified minimum gross revenues in
any month. The performance goal is likely to be met if the WilTel Acquisition is
consummated. In addition, the Plan Committee has established $1,000,000 as the
maximum bonus for the Chief Executive Officer under the 1995 Plan. If such
performance goal is not met, the Chief Executive Officer would not be entitled
to a bonus under the 1995 Plan. Any bonus under the Annual Performance Bonus
Plan is independent of the 1995 Plan.
 
     AMENDMENT.  The Plan Committee may terminate or amend the 1995 Plan, from
time to time, with or without notice. Section 162(m) requires shareholder
approval of certain material amendments to the 1995 Plan, such as a change in
the maximum amount of a participant's bonus, the method of determining the
maximum amount of a participant's bonus and a change in the class of persons
eligible to participate in the 1995 Plan.
 
                                   * * * * *
 
     The Committee believes that the 1995 Plan establishes appropriate objective
guidelines for establishing incentive compensation for LDDS's Chief Executive
Officer, which qualifies as "performance-based" compensation within the purview
of Section 162(m). The Committee will continue to consider qualitative or other
factors not included in the 1995 Plan in making executive compensation
decisions, including base salary and annual and long-term incentive award
determinations.
 
     The affirmative vote of a number of shares of LDDS Common Stock and Series
1 Preferred Stock and Series 2 Preferred Stock on an as-if-converted basis,
voting as a single class, represented in person or by proxy at a meeting where a
quorum is present, in excess of the number of shares voting against the 1995
Plan is required to adopt the 1995 Plan. A majority of the votes entitled to be
cast in the election constitutes a quorum. Shares voted to "abstain" will be
considered to be present for purposes of establishing a quorum but will have no
effect on the proposal. Shares as to which a broker indicates it lacks authority
to vote on Item 2 and which are not voted will be considered not present for
purposes of determining the existence of a quorum and the requisite majority
vote.
 
     The Board of Directors recommends a vote "FOR" adoption of the 1995 Plan.
 
                                 LEGAL MATTERS
 
     Bryan Cave, St. Louis, Missouri, has rendered its opinion that the shares
of LDDS Common Stock to be issued in the Merger have been duly authorized and,
if and when issued pursuant to the terms of the Merger Agreement, will be
validly issued, fully paid and nonassessable.
 
     O'Melveny & Myers has rendered the opinion referred to under "Plan of
Merger -- Certain Federal Income Tax Consequences."

                          AGREEMENT AND PLAN OF MERGER
 
     This Agreement and Plan of Merger (the "Agreement") is made as of August 1,
1994, by and among LDDS Communications, Inc., a Georgia corporation (the
"Company"), 123 Corp., a Delaware corporation and wholly owned subsidiary of the
Company ("Acquisition Subsidiary"), and IDB Communications Group, Inc., a
Delaware corporation ("Target").
 
                                    RECITALS
 
     A. The respective Boards of Directors of Target, Acquisition Subsidiary and
the Company have approved the merger (the "Merger") of Acquisition Subsidiary
with and into Target in accordance with the laws of the State of Delaware and
the provisions of this Agreement.
 
     B. Target, Acquisition Subsidiary and the Company desire to make certain
representations, warranties and agreements in connection with, and establish
various conditions precedent to, the Merger.
 
     NOW, THEREFORE, in consideration of the premises and the mutual covenants
and agreements hereinafter set forth, the parties hereto agree as follows:
 
                                   ARTICLE I
 
                              TERMS OF THE MERGER
 
     1.1  THE MERGER. Upon the terms and subject to the conditions of this
Agreement, the Merger shall be consummated in accordance with the Delaware
General Corporation Law (the "Delaware Code"). At the Effective Time (as defined
in Section 1.2, below), upon the terms and subject to the conditions of this
Agreement, Acquisition Subsidiary shall be merged with and into Target in
accordance with the Delaware Code and the separate existence of Acquisition
Subsidiary shall thereupon cease, and Target, as the surviving corporation in
the Merger (the "Surviving Corporation"), shall continue its corporate existence
under the laws of the State of Delaware as a subsidiary of the Company. The
parties shall prepare and execute a certificate of merger in substantially the
form attached hereto as Exhibit 1.1 (the "Certificate of Merger") in order to
comply in all respects with the requirements of the Delaware Code and with the
provisions of this Agreement.
 
     1.2  EFFECTIVE TIME. The Merger shall become effective at the time of the
filing of the Certificate of Merger with the Secretary of State of Delaware in
accordance with the applicable provisions of the Delaware Code or at such later
time as may be specified in the Certificate of Merger. The Certificate of Merger
shall be filed as soon as practicable after all of the conditions set forth in
this Agreement have been satisfied or waived by the party or parties entitled to
the benefit of the same. Target and the Company shall agree upon the time of
such filing and the place where the closing of the Merger (the "Closing") shall
occur. The time when the Merger shall become effective is herein referred to as
the "Effective Time" and the date on which the Effective Time occurs is herein
referred to as the "Closing Date."
 
     1.3  MERGER CONSIDERATION. Subject to the provisions of this Agreement, at
the Effective Time, each issued and outstanding share ("Target Shares") of
common stock, par value $.01 per share, of Target (the "Target Common Stock")
shall, by virtue of the Merger and without any action on the part of the holder
thereof, be converted into the right to receive, and there shall be paid and
issued as hereinafter provided in exchange for the Target Shares, the following
consideration (the "Merger Consideration"): (a) if the Share Value (as
hereinafter defined) is $16.00 or lower, .520231 of a share of the common stock
of the Company, par value $.01 per share (the "Company Stock"); (b) if the Share
Value is $22.00 or greater, .450867 of a share of Company Stock; or (c) if the
Share Value is greater than $16.00 but lower than $22.00, that portion of a
share of Company Stock set forth next to the applicable Share Value listed below
(provided that if the Share Value falls between any two of the Share Values
listed below, the portion of a share of Company Stock
 
                                       A-1
<PAGE>   131
 
shall be that applicable to the lower of the two Share Values). The applicable
exchange ratio determined pursuant to the foregoing is herein referred to as the
"Exchange Ratio."

     For purposes hereof, the "Share Value" shall be an amount equal to the
average closing trade price of the Company Stock for the thirty (30) consecutive
trading days prior to the date three (3) business days prior to the Closing Date
as reported on the Nasdaq Stock Market.
 
     No fractional shares of the Company Stock shall be issued pursuant to the
Merger nor will any fractional share interest involved entitle the holder
thereof to vote, to receive dividends or to exercise any other rights of a
shareholder of the Company. In lieu thereof, any person who would otherwise be
entitled to a fractional share of the Company Stock pursuant to the provisions
hereof shall receive an amount in cash equal to the value of such fractional
share. The value of such fractional share shall be the product of such fraction
(rounded down to the nearest hundredth of a share) multiplied by the Share
Value.
 
     Each share of Target Common Stock held in the treasury of Target or by a
wholly owned subsidiary of Target shall be cancelled as of the Effective Time
and no Merger Consideration shall be payable with respect thereto. From and
after the Effective Time, there shall be no further transfers on the stock
transfer books of Target of any of the Target Shares.
 
     Subject to the provisions of this Agreement, at the Effective Time, the
shares of Acquisition Subsidiary common stock outstanding immediately prior to
the Merger shall be converted, by virtue of the Merger and without any action on
the part of the holder thereof, into one share of the common stock of the
Surviving Corporation (the "Surviving Corporation Common Stock"), which one
share of the Surviving Corporation Common Stock shall constitute all of the
issued and outstanding capital stock of the Surviving Corporation.
 
     1.4  STOCKHOLDERS' RIGHTS UPON MERGER. Upon consummation of the Merger, the
certificates which theretofore represented Target Shares (the "Certificates")
shall cease to represent any rights with respect thereto, and, subject to
applicable Law (as hereinafter defined) and this Agreement, shall only represent
the right to receive the Merger Consideration and the amount of cash, if any,
payable in lieu of fractional shares of the Company Stock into which their
Target Shares have been converted pursuant to this Agreement. Target represents
and warrants that the holders of the Target Shares are not entitled to appraisal
rights under applicable Law or the Certificate of Incorporation of Target,
provided the conditions of Section 262(b)(1) of the Delaware Code are satisfied
and the provisions of Section 262(b)(2) of the Delaware Code are not applicable.

     1.5  SURRENDER AND EXCHANGE OF SHARES. After the Effective Time, each
holder of a Target Share shall surrender and deliver the Certificates to First
Union National Bank of North Carolina or such other bank or trust company as may
be designated by the Company (the "Exchange Agent") together with a duly
completed and executed transmittal letter provided by the Exchange Agent. Upon
such surrender and delivery, the holder shall receive a certificate representing
the number of whole shares of the Company Stock to which such holder is entitled
pursuant to this Agreement plus any cash payable in lieu of fractional shares.
Until so surrendered and exchanged, each outstanding Certificate after the
Effective Time shall be deemed for all purposes to evidence the right to receive
that number of whole shares of the Company Stock into which the Target Shares
have been converted pursuant to this Agreement, plus any cash payable in lieu of
fractional shares; provided, however, that no dividends or other distributions,
if any, in respect of the shares of the Company Stock, declared after the
Effective Time and payable to holders of record after the Effective Time, shall
be paid to the holders of any unsurrendered Certificates until such Certificates
and transmittal letters are surrendered and delivered as provided herein.
Subject to applicable Law, after the surrender and exchange of Certificates, the
record holders thereof will be entitled to receive any such dividends or other
distributions without interest thereon, which theretofore have become payable
with respect to the number of shares of the Company Stock for which such
Certificates were exchangeable. Holders of any unsurrendered Certificates shall
not be entitled to vote the Company Stock until such Certificates are exchanged
pursuant to this Agreement.
 
     1.6  OPTIONS. At the Effective Time, the Company shall cause each holder of
a then-outstanding and unexercised option or warrant exercisable for shares of
Target Common Stock ("Target Options") to receive, by virtue of the Merger and
without any action on the part of the holder thereof, options or warrants
exercisable for shares of Company Stock having the same terms and conditions as
the Target Options except that the exercise price and the number of shares
issuable upon exercise shall be divided and multiplied, respectively, by the
Exchange Ratio. The Company acknowledges that at the Effective Time, all such
options shall be vested and exercisable to the extent provided in the Target
Options or, subject to the provisions of this Agreement, applicable employment
agreements. The Company shall file or cause to be filed all registration
statements on Form S-8 or other appropriate form and all other registrations and
qualifications as may be necessary in connection with the sale of Company Stock
contemplated by such Target Options subsequent to the Effective Time.
 
     1.7  CERTIFICATE OF INCORPORATION. At and after the Effective Time, the
Certificate of Incorporation of Target shall be the Certificate of Incorporation
of the Surviving Corporation (subject to any subsequent amendment).
 
     1.8  BYLAWS. At and after the Effective Time, the Bylaws of Target shall be
the Bylaws of the Surviving Corporation (subject to any subsequent amendment).

successors are duly elected or appointed, the directors and the officers of the
Surviving Corporation shall be as follows:

     and supplements thereto, being herein referred to as the "Registration
     Statement"), including a prospectus/joint proxy statement satisfying all
     applicable requirements of applicable state securities laws, the Securities
     Act and the Securities Exchange Act of 1934, as amended, and the rules and
     regulations thereunder (the "Securities Exchange Act"). Such

          (b) Target will furnish the Company with such information concerning
     Target and its subsidiaries as is necessary in order to cause the
     Prospectus/Joint Proxy Statement, insofar as it relates to Target and its
     subsidiaries, to comply with applicable Law. None of the information
     relating to Target and its subsidiaries supplied by Target for inclusion in
     the Prospectus/Joint Proxy Statement will be false or misleading with
     respect to any material fact or will omit to state any material fact
     required to be stated therein or necessary in order to make the statements
     therein, in light of the circumstances under which they are made, not
     misleading. Target agrees promptly to advise the Company if at any time
     prior to the respective meetings of stockholders of Target or the Company
     any information provided by it in the Prospectus/Joint Proxy Statement is
     or becomes incorrect or incomplete in any material respect and to provide
     the Company with the information needed to correct such inaccuracy or
     omission. Target will furnish the Company with such supplemental
     information as may be necessary in order to cause the Prospectus/Joint
     Proxy Statement, insofar as it relates to Target and its subsidiaries, to
     comply with applicable Law after the mailing thereof to the stockholders of
     Target or the Company.
 
          (c) The Company will furnish Target with such information concerning
     the Company and its subsidiaries as is necessary in order to cause the
     Prospectus/Joint Proxy Statement, insofar as it relates to the Company and
     its subsidiaries, to comply with applicable Law. None of the information
     relating to the Company and its subsidiaries supplied by the Company for
     inclusion in the Prospectus/Joint Proxy Statement will be false or
     misleading with respect to any material fact or will omit to state any
     material fact required to be stated therein or necessary in order to make
     the statements therein, in light of the circumstances under which they were
     made, not misleading. The Company agrees promptly to advise Target if at
     any time prior to the respective meetings of stockholders of Target or the
     Company any information provided by it in the Prospectus/Joint Proxy
     Statement is or becomes incorrect or incomplete in any material respect and
     to provide Target with the information needed to correct such inaccuracy or
     omission. The Company will furnish Target with such supplemental
     information as may be necessary in order to cause the Prospectus/Joint
     Proxy Statement, insofar as it relates to the Company and its subsidiaries,
     to comply with applicable Law after the mailing thereof to stockholders of
     Target or the Company.
 
          (d) The Company, as promptly as practicable, will file the
     Registration Statement with the SEC and appropriate materials with
     applicable state securities agencies and will use all reasonable efforts to
     cause the Registration Statement to become effective under the Securities
     Act and all such state filed materials to comply with applicable state
     securities laws. Target authorizes the Company to utilize in the
     Registration Statement and in all such state filed materials, the
     information concerning Target and its subsidiaries provided to the Company
     in connection with, or contained in, the Prospectus/Joint Proxy Statement.
     The Company promptly will advise Target when the Registration Statement has
     become effective and of any supplements or amendments thereto, and the
     Company will furnish Target with copies of all such documents. Target shall
     not distribute any written material that would constitute, as advised by
     O'Melveny & Myers or Richards, Layton & Finger, or other reputable counsel
     to Target, a "prospectus" relating to the Merger or the Company Stock
     within the meaning of the Securities Act or any applicable state securities
     law without the prior written consent of the Company.
 
     1.12  TAX-FREE REORGANIZATION. The parties intend that the Merger qualify
as a tax-free reorganization pursuant to Section 368 of the Internal Revenue
Code of 1986, as amended, and the regulations thereunder (the "Code").
 
     1.13  ADDITIONAL ACTIONS. If, at any time after the Effective Time, the
Surviving Corporation shall consider or be advised that any deeds, bills of

material adverse effect on the business, assets (including, but not limited to,
intangible assets), condition (financial or otherwise), properties (including,
but not limited to, intangible properties), liabilities or the results of
operations of Target and the Target Subsidiaries taken as a whole ("Target

Target Ancillary Agreements, the consummation of the transactions contemplated

other than as set forth in Exhibit 2.7 attached hereto or in a Target Securities
Filing, or such as are not presently expected by the management of Target, in
the reasonable exercise of its judgment as advised by counsel, to have a Target
Material Adverse Effect. No event has occurred as a consequence of which Target
would be required to file a Current Report on Form 8-K pursuant to the
requirements of the Securities Exchange Act as to which such a report has not

incur any material liability. A "Benefit Plan" shall constitute (i) an employee
benefit plan as defined in Section 3(3) of the Employee Retirement Income

or supplemental compensation, retirement, thrift, stock purchase or stock option
plan, or any other compensation, welfare, fringe benefit or retirement plan,

formal or informal, oral or written, providing for benefits for or the welfare
of any or all of the current or former employees or agents of Target or any
Target Subsidiary or their beneficiaries or dependents, (b) a multi-employer
plan as defined in Section 3(37) of ERISA, or (c) a multiple employer plan as
defined in Section 413 of the Code.

arrangements; (ii) annual reports on the Form 5500 series for the last year;
(iii) financial statements and/or annual and periodic accountings of plan assets

each Benefit Plan while maintained or contributed to by Target or a Target
Subsidiary: (i) if intended to qualify under Code Sections 401(a) or 403(a),
such Benefit Plan has received a favorable determination letter from the IRS
that it so qualifies, and its trust is exempt from taxation under Code Section
501(a) and nothing has since occurred to cause the loss of the Benefit Plan's
qualification; (ii) such Benefit Plan has been administrated in substantial
accordance with its terms and applicable Laws; (iii) to the knowledge of the
Target, no event has occurred and there exist no circumstances under which
Target, a Target Subsidiary or the Surviving Corporation would incur liability
under ERISA, the Code or otherwise in addition to the payment of nondelinquent
benefits, contributions and expenses currently contemplated by such Benefit
Plans; (iv) no accumulated funding deficiency as defined in Code Section 412 has
occurred or exists; (v) no non-exempt prohibited transaction as defined under
ERISA and the Code has occurred; (vi) no reportable event as defined in Section
4043 of ERISA has occurred (excluding events for which the 30-day notice
requirement has been waived); (vii) all contributions and premiums due have
fully been made and paid on a timely basis; and (viii) all contributions made or
required to be made under any Benefit Plan intended to be deductible meet the
requirements for deductibility under the Code, and all contributions accrued
prior to the Effective Time which have not been made have been properly recorded
on the books of Target, except in the cases of clauses (iii) - (viii), above,
for any deviations from the foregoing which do not or would not have a Target
Material Adverse Effect.
 
     Neither Target nor any Target Subsidiary has any material liability, joint
or otherwise, for any withdrawal liability (potential, contingent or otherwise)
under Title IV of ERISA for a complete or partial withdrawal from any
multi-employer plan by any member of a controlled group of employers (as used in
ERISA) of which Target is or was a member.
 
     With respect to each Benefit Plan which is subject to Title IV of ERISA:
(i) except as disclosed in the Target Financial Statements (or footnotes
thereto), as of the Effective Time, the market value of its assets (exclusive of
any contribution due to such Benefit Plan) equals or exceeds the present value
of benefit liabilities as of the latest actuarial evaluation date for such plan
(but not earlier than 12 months prior to the date hereof), and since the last
evaluation date, there have been no amendments to such plans that materially
increase the present value of actuarial benefits nor any other material adverse
changes in the funding status of such plan, and (ii) neither Target nor any
Target Subsidiary has incurred nor is expected to incur any actual or contingent
liability arising from a partial or complete plan termination, except in each
case, for any deviations from the foregoing which do not or would not have a
Target Material Adverse Effect.
 
     With respect to each Benefit Plan which is a welfare plan (as defined in
ERISA Section 3(1)): (i) any liability for medical or death benefits with

Statements (or footnotes thereto) to the extent required to be so set forth by
applicable accounting principles; (ii) there are no reserves, assets, surplus or
prepaid premiums under any such plan; (iii) except as set forth in Exhibit

any deviations from the foregoing which do not or would not have a Target
Material Adverse Effect.
 
     Except as contemplated by Sections 1.6, 4.1 and 4.8 hereof and as set forth
in Exhibit 2.14(d) attached hereto, the consummation of the Merger will not (i)
entitle any individual to severance pay, or (ii) accelerate the time of payment
or vesting of benefits or increase the amount of compensation due to any
individual.
 
     2.15  TAXES AND RETURNS. (a) Except as disclosed in Exhibit 2.15 attached
hereto, Target and each of the Target Subsidiaries has timely filed, or caused

any Target Subsidiary for any alleged deficiency in any Tax, and Target does not

Subsidiary (other than those for which adequate reserves in the Target Financial
Statements have been established). Neither Target nor any Target Subsidiary has

Target nor any of the Target Subsidiaries has made an election under Section 338
of the Code or has taken any action that would result in any tax liability of
Target or any of the Target Subsidiaries as a result of a deemed election within
the meaning of Section 338 of the Code. Except as set forth in Exhibit 2.15

                      ADDITIONAL COVENANTS OF THE COMPANY
 
     The Company covenants and agrees as follows:

        to acquire or sell any shares of, the capital stock or other securities

        stock, or redeem, purchase or otherwise acquire or offer to acquire any
        shares of its capital stock or other securities;
 
             (iv) (a) except for debt (including, but not limited to,
        obligations in respect of capital leases) not in excess of $175,000,000
        in the aggregate for all entities combined, create, incur or assume any
        short-term debt, long-term debt or obligations in respect of capital
        leases; (b) assume, guarantee, endorse or otherwise become liable or
        responsible (whether directly, indirectly, contingently or otherwise)
        for the obligations of any person, except for obligations permitted by
        this Agreement of any wholly owned subsidiary of the Company in the
        ordinary course of business consistent with past practice; or (c) as to
        the Company, merge or consolidate with any other person, unless the
        Company is the surviving entity; except, in the case of clauses (a) and
        (b), in the ordinary course of business consistent with past practice or
        incident to a Significant Acquisition (as hereinafter defined) or an
        action referenced in Section 5.1(c), below;
 
             (v) sell, transfer, mortgage, pledge or otherwise dispose of, or

        consistent with past practice; or
 
             (vi) agree, commit or arrange to do any of the foregoing.
 
          Furthermore, the Company covenants, represents and warrants that from
     and after the date hereof, unless Target shall otherwise expressly consent
     in writing, the Company shall, and the Company shall cause each Company
     Subsidiary to, use its or their reasonable business efforts to comply in
     all material
 
                                      A-26
<PAGE>   156
 
     respects with all Laws applicable to it or any of its properties, assets or
     business and maintain in full force and effect all the Company Permits
     necessary for, or otherwise material to, such business.
 
          (b) Consultation with Target Re: Significant Acquisitions. The Company
     shall notify Target of its intention to make any Significant Acquisition
     (as hereinafter defined) promptly after the execution of any agreement
     providing therefor. The Company shall promptly thereafter provide Target
     (and Target's financial and accounting advisors and legal counsel) with
     such information and documentation relating to the terms of such
     Significant Acquisition and the participants therein as they may reasonably
     request, subject to the proposed recipient executing and delivering such
     confidentiality undertaking as the participants therein may reasonably
     require. Within 10 days after the date that the Company is notified by
     Target that no further information is required pursuant to the foregoing
     with respect to any such Significant Acquisition, and in any event within
     30 days after the notice required by this Section 5.1(b) is given by the
     Company to Target of the intention to make the Significant Acquisition,
     Target shall, by written notice to the Company, either grant its consent
     thereto or inform the Company (if such is the case) that Target's Board of
     Directors, in the exercise of its fiduciary duties under applicable Law as
     advised by O'Melveny & Myers or Richards, Layton & Finger or other
     reputable counsel to Target, has determined that the Merger is no longer in
     the best interests of the stockholders of Target and that Target is
     terminating this Agreement pursuant to the provisions of Section
     7.1(iii)(c) hereof. The failure of Target to so notify the Company shall

limitation, the Current Report on Form 8-K filed with the SEC on May 31, 1994,

statement, representation, warranty or other disclosure made by Target or any of
Target's directors, officers, employees, accountants, agents, or advisers
respecting the Accounting Contingency, or any facts or circumstances relating to
the Accounting Contingency, for any purpose. Notwithstanding any representation,
warranty or covenant of Target contained in this Agreement, or any condition to
the obligations of the Company provided for in this Agreement, the Company
acknowledges (a) the existence of the Accounting Contingency, (b) that, but for
the exclusion thereof from the definition of "Target Material Adverse Effect,"
the Accounting Contingency

might otherwise constitute or give rise to a Target Material Adverse Effect, and
(c) that no representation or warranty of Target set forth in this Agreement
shall be deemed to have been inaccurate, breached or violated, no covenant of
Target contained in this Agreement shall be deemed to have been breached and no
condition to the obligations of the Company set forth in this Agreement shall be
deemed to be unsatisfied as a result of the Accounting Contingency or the claims
of any persons (or the costs, expenses, liabilities or damages relating to such
claims) arising out of or in connection with the Accounting Contingency, except
and only to the extent that such inaccuracy, breach, violation or unsatisfied
condition is attributable to a false or misleading statement with respect to any
material fact or the omission to state any material fact required to be stated
therein or necessary in order to make the statements made therein, in light of
the circumstances under which they were made, not misleading in the Relevant
Statements the reliability of which is not otherwise questioned by other

originals of such comments and responses have been provided to the Company prior
to the date hereof), relating to accounting disagreements between Target and
Deloitte & Touche, or the resignation on May 23, 1994 of Deloitte & Touche as
Target's auditors, or accounting adjustments or restatements relating to the

     definitive agreement with respect to any (1) acquisition or purchase by any
     person of all or a significant portion of the assets of, or any significant

     7.2  PROCEDURE AND EFFECT OF TERMINATION. In the event of termination of
this Agreement and abandonment of the Merger by Target or the Company pursuant
to Section 7.1, above, written notice thereof shall promptly be given to the
other party hereto and this Agreement shall terminate and the Merger shall be
abandoned without further action by either of the parties hereto. If this
Agreement is terminated as provided herein, neither party hereto shall have any
liability or further obligation to the other party under the terms of this
Agreement except for breach by such party or with respect to the provisions of
Sections 7.2, 8.1 and 8.7 hereof. In the event of termination of this Agreement
(i) by the Company as provided in Section 7.1(iv)(a) hereof by reason of a
breach that was neither willful nor undertaken in bad faith, (ii) by the Company
as provided in Section 7.1(iv)(b) hereof by reason of a breach or failure by
Target that was neither willful nor undertaken in bad faith, or (iii) by Target
as provided in Subsection 7.1(vi), above, Target promptly after such termination
shall pay the Company in cash the sum of $8,000,000; provided, however, that no
such payment shall be required in the event of termination pursuant to
Subsection 7.1(vi)(b), above, unless and until Target, within a period of six
months after said termination, enters into an agreement in principle, letter of
intent or definitive agreement respecting an Alternative Transaction. The amount
of such payment represents a reasonable, good faith estimate of the damages in
such event and does not constitute a penalty. Such payment shall be the only
right or remedy of the Company for the circumstances described and such payment
shall constitute liquidated damages in the event of such termination with no
other liability or obligation on the part of Target. In the event of termination
of this Agreement (i) by Target as provided in Subsection 7.1(iii)(a) hereof by
reason of a breach that was neither willful nor undertaken in bad faith, or (ii)
by Target as provided in Subsection 7.1(iii)(b) hereof by reason of a breach or
failure by the Company that was neither willful nor undertaken in bad faith, the
Company promptly after such termination shall pay Target in cash the sum of
$8,000,000. The amount of such payment represents a reasonable, good faith
estimate of the out-of-pocket costs of Target in such event and does not
constitute a penalty. Such payment shall be the only right or remedy of Target
for the circumstances described and such payment shall constitute liquidated
damages in the event of such termination with no other liability or obligation
on the part of the Company.

necessary to secure any required Consents as to which the other party has been
advised, or (iv) consented to in writing by the Company and Target, this

the extent required by such disclosure obligations, the Company or Target, after
consultation with the other party, may file with the SEC a Current Report on
Form 8-K pursuant to the Securities Exchange Act with respect to the Merger,
which report may include, among other things, financial statements and pro forma
financial information with respect to the other party. In connection with any

Securities Act, Target or the Company, after consultation with the other party,

therein with respect to the Merger, including, but not limited to, financial
statements and pro forma financial information with respect to the other party,
and thereafter distribute said prospectus. The Company and Target shall
cooperate with the other and provide such information and documents as may be
required in connection with any such filings. In the event the Merger is not
consummated, each party shall return to the other all documents furnished by the
other and will hold in absolute confidence any information obtained from the
other party except to the extent (i) such party is required to disclose such
information by Law or such disclosure is necessary or desirable in connection
with the pursuit or defense of a claim, (ii) such information was known by such
party prior to such disclosure or was thereafter developed or obtained by such
party independent of such disclosure, or (iii) such information becomes
generally available to the public or is otherwise no longer confidential. Prior
to any disclosure of information pursuant to the exception in clause (i) of the
preceding sentence, the party intending to disclose the same shall so notify the
party which provided the same in order that such party may seek a protective
order or other appropriate remedy should it choose to do so.
 
     8.2  AMENDMENT AND MODIFICATION. To the extent permitted by applicable Law,
this Agreement may be amended, modified or supplemented only by a written

Target on the other hand, only by a written instrument signed by the party
granting such waiver, but such waiver or failure to insist upon strict
compliance with such obligation, covenant, agreement or condition shall not
operate as a waiver of, or estoppel with respect to, any subsequent or other
failure. Whenever this Agreement requires or permits consent by or on behalf of
any party hereto, such consent shall be given in writing in a manner consistent
with the requirements for a waiver of compliance as set forth in this Section
8.3.

Board of Directors
LDDS Communications, Inc.
515 East Amite Street
Jackson, Mississippi 39201
 
Gentlemen:
 
     LDDS Communications, Inc. ("LDDS" or the "Company"), IDB Communications
Group, Inc. ("IDB") and 123 Corp. ("Acquisition Subsidiary"), a wholly owned
subsidiary of the Company have entered into that certain Agreement and Plan of
Merger dated as of August 1, 1994 (the "Agreement"). Pursuant to the Agreement,
Acquisition Subsidiary will be merged with and into IDB and IDB will be the
surviving corporation (the "Surviving Corporation") and will become a wholly
owned subsidiary of LDDS (the "Merger"). If the Merger is consummated, each
share of common stock, $.01 par value per share, of IDB will be converted into
the right to receive a specified fraction of a share of common stock, par value
$.01 per share of LDDS ("LDDS Common Stock"), which fraction is referred to
herein as the "Exchange Ratio". If a share value (as defined in the Agreement)
is equal to or less than $16.00, the Exchange Ratio will be 0.520231. If the
share value is equal to or greater than $22.00, the Exchange Ratio will be
0.4508767. If the share value is greater than $16.00 but less than $22.00, the
Exchange Ratio will be the amount greater than 0.458767 and less than 0.520231
set forth opposite the applicable share value set forth in Section 1.3 of the
Agreement.
 
     Breckenridge Securities Corp., as a customary part of its investment
banking business, is engaged in the valuation of businesses and their securities
in connection with mergers and acquisitions. We are familiar with LDDS and its
business and have, on our own or through our affiliate The Breckenridge Group,
Inc., provided investment banking services to LDDS since 1988 for which we were
compensated. In connection with the Merger, we have acted as LDDS' financial
advisor and have participated in certain of the negotiations leading to the
execution of the Agreement and will receive compensation for such services that
is contingent upon the consummation of the Merger. In addition, LDDS has agreed
to indemnify us for certain liabilities, if any, arising out of or in connection
with such services or this opinion. The principals of The Breckenridge Group,
Inc. own in the aggregate 696,610 shares of LDDS Common Stock and options to
acquire 287,850 shares of LDDS Common Stock.
 
     In connection with this opinion, we have reviewed and analyzed: (i) certain
publicly available financial and other information concerning LDDS and IDB, (ii)
certain internal financial statements including IDB management's estimates of
the restated results of operations for IDB for the quarter ended March 31, 1994,
and other financial and operating data concerning LDDS and IDB prepared by
respective managements of LDDS and IDB, (iii) certain financial projections
prepared by the respective managements of LDDS and IDB, (iv) current and
historical reported market prices and trading activity for the LDDS Common Stock
and the IDB Common Stock, (v) a comparison of the financial performance of LDDS
and IDB and the prices and trading activity of the LDDS Common Stock and IDB
Common Stock with the financial performance of certain other comparable publicly
traded companies and their securities, (vi) the financial terms of certain
recent business combinations in the telecommunications industry that we deemed
relevant, (vii) certain assumptions prepared jointly by the managements of LDDS
and IDB concerning potential cost savings that could be achieved from the
realization of economies of scale resulting from networking and operating
efficiencies (the "Savings Assumptions"), and (viii) the Agreement and certain
related documents. In addition, we engaged in discussions with the management of
LDDS and IDB concerning their respective businesses, assets, liabilities,
condition (financial and otherwise) and prospects and performed such other
studies and analyses and reviewed such other information as it considered
appropriate.
 
                                       B-1
<PAGE>   169
 
     We have not independently verified any of the financial or other
information reviewed by us for purposes of this opinion, and we have assumed the
accuracy, completeness and fairness thereof. With respect to the financial
projections of LDDS and IDB and the Savings Assumptions, we have assumed that
they were reasonably prepared on bases reflecting the best currently available
judgments and estimates of the respective managements of LDDS and IDB as to the
future financial performance of their respective companies. We have also assumed
that, in the course of obtaining the necessary regulatory or governmental
approvals for the Merger or in connection with any change in applicable law, no
restriction would be imposed on the Surviving Corporation in the Merger that
would have a material adverse effect on the business of the Surviving
Corporation or the contemplated benefits of the Merger, including those
contemplated by the Savings Assumptions. We have not made an independent
evaluation or appraisal of the assets of LDDS and IDB, nor have we been
furnished with any such appraisal. In addition, with LDDS' permission, we did
not independently appraise any potential or pending litigation involving LDDS or
IDB. Our opinion is based on economic, market and other conditions existing on,
and the information available to us as of, the date hereof.
 
     Based on and subject to the foregoing and such other matters as we
considered relevant, we are of the opinion as of the date hereof that the
Exchange Ratio is fair, from a financial point of view, to the holders of LDDS
Common Stock and preferred stock par value $.01 per share of LDDS.
 
                                            Very truly yours,

The Board of Directors

Gentlemen:
 
     You have requested our opinion as to the fairness from a financial point of
view to the holders of the outstanding shares of common stock (the "Common
Stock") of IDB Communications Group, Inc. ("IDB" or the "Company") of the
consideration to be received by such shareholders in connection with the
proposed merger of 123 Corp. ("Merger Sub"), a wholly owned subsidiary of LDDS
Communications, Inc. ("LDDS"), with and into IDB (the "Proposed Transaction")
pursuant to the Agreement and Plan of Merger to be dated as of August 1, 1994,
among LDDS, Merger Sub, and IDB (the "Agreement").
 
     We understand that the terms of the Agreement provide, among other things,
that each issued and outstanding share of Common Stock shall be converted into
the right to receive not less than 0.450867 shares, nor more than 0.520231
shares, of common stock of LDDS, as more fully set forth in the Agreement. We
also understand that the Agreement provides that the Proposed Transaction will
take place whether or not the proposed acquisition of Williams
Telecommunications Group, Inc. ("Wiltel") by LDDS (the "Wiltel Acquisition")
occurs, and for the purposes of this opinion we have reviewed and analyzed the
Proposed Transaction both with and without the Wiltel acquisition. For purposes
of this opinion, we have assumed that the Proposed Transaction will qualify as a
reorganization under the United States Internal Revenue Code for the
shareholders of the Company and that the Proposed Transaction will be accounted
for as a pooling of interests.
 
     Hambrecht & Quist Incorporated ("Hambrecht & Quist"), as part of its
investment banking services, is regularly engaged in the valuation of businesses
and their securities in connection with mergers and acquisitions, corporate
restructurings, negotiated underwritings, secondary distributions of listed and
unlisted securities, private placements and valuations for corporate and other
purposes. We have acted as financial advisor to the Board of Directors of IDB in
connection with the Proposed Transaction and will receive a fee for our
services, which include the rendering of this opinion.
 
     In the past, we have provided investment banking and other financial
advisory services to IDB and have received fees for rendering these services. We
are familiar with IDB, having acted as a managing underwriter of the Company's
Common Stock in November 1991, May 1993 and November 1993 and of the Company's
5% Convertible Subordinated Notes in August 1993. IDB has been included on the
Hambrecht & Quist Selected Stock List since September 1992. In the ordinary
course of business, Hambrecht & Quist acts as a

market maker and broker in the publicly traded securities of IDB and receives
customary compensation in connection therewith, and also provides research
coverage for IDB. In the ordinary course of business, Hambrecht & Quist actively
trades in the publicly traded securities of IDB for its own account and for the
accounts of its customers and, accordingly, may at any time hold a long or short
position in such securities. In addition, Hambrecht & Quist is a defendant in
certain of the consolidated actions pending in the United States District Court
for the Central District of California under the caption "In re IDB
Communications Group, Inc. Securities Litigation," Master File No.
CV-94-3618-RG(JGx).
 
     In connection with our review of the Proposed Transaction, and in arriving
at our opinion, we have, among other things:
 
          (i) reviewed the publicly available consolidated financial statements
     of the Company for recent years and interim periods to date and certain
     other relevant financial and operating data of the Company (including its
     capital structure) made available to us from published sources and from the
     internal records of the Company;
 
          (ii) discussed with certain members of the management of the Company
     the business, financial condition and prospects of the Company;
 
          (iii) reviewed certain financial and operating information, including
     certain projections provided by the management of the Company, relating to
     the Company and discussed such projections with certain members of the
     management of the Company;
 
          (iv) reviewed the publicly available consolidated financial statements
     of LDDS for recent years and interim periods to date and certain other
     relevant financial and operating data of LDDS (including its capital
     structure) made available to us from published sources and from the
     internal records of the Company;
 
          (v) discussed with certain members of the management of LDDS the
     business, financial condition and prospects of LDDS;
 
          (vi) reviewed certain financial and operating information, including
     certain projections provided by the management of LDDS, relating to LDDS
     (with and without giving effect to the Wiltel Acquisition) and discussed
     such projections with certain members of the management of LDDS;
 
          (vii) reviewed the recent reported prices and trading activity for the
     common stock of the Company and LDDS and compared such information and
     certain financial information of the Company and LDDS with similar
     information for certain other companies engaged in businesses we consider
     comparable to those of the Company and LDDS;
 
          (viii) discussed with certain members of the management of Wiltel the
     business, financial condition and prospects of Wiltel;
 
          (ix) reviewed certain financial and operating information, including
     audited historical financial statements of the Network Services operations
     of Wiltel and certain projections provided by the management of Wiltel,
     relating to Wiltel and discussed such projections with certain members of
     the management of Wiltel;
 
          (x) discussed with parties other than LDDS the possibility of a
     transaction or series of transactions involving a business combination with
     the Company;
 
          (xi) reviewed the terms, to the extent publicly available, of certain
     comparable acquisition transactions;
 
          (xii) reviewed the Agreement; and
 
          (xiii) performed such other analyses and examinations and considered
     such other information, financial studies, analyses and investigations and
     financial, economic and market data as we deemed relevant.

     We have not independently verified any of the information concerning the
Company, LDDS or Wiltel considered in connection with our review of the Proposed
Transaction and, for purposes of the opinion set forth herein, we have assumed
and relied upon the accuracy and completeness of all such information. We have
not prepared or obtained any independent evaluation or appraisal of any of the
assets or liabilities of the Company, LDDS or Wiltel, nor have we conducted a
physical inspection of the properties and facilities of the Company, LDDS or
Wiltel. Furthermore, with your permission, we have not prepared or obtained any
evaluation or appraisal of any potential or pending litigation that may involve
the Company, LDDS or Wiltel. With respect to the financial forecasts and
projections made available to us and used in our analyses, we have assumed that
they reflect the best currently available estimates and judgments of the
expected future financial performance of the Company, LDDS and Wiltel. For
purposes of this opinion, we have assumed that neither the Company, LDDS nor
Wiltel is a party to any pending transactions, including external financings,
recapitalizations or merger discussions, other than the Proposed Transaction,
the Wiltel Acquisition, and those in the ordinary course of conducting their
respective businesses. Our opinion is necessarily based upon market, economic,
financial and other conditions as they exist and can be evaluated as of the date
of this letter and any change in such conditions would require a reevaluation of
this opinion. We express no opinion as to the price at which LDDS Common Stock
will trade subsequent to the Effective Time (as defined in the Agreement).
 
     Our advisory services and the opinion expressed herein are provided solely
for the use of the Board of Directors of IDB in its evaluation of the Proposed
Transaction and are not on behalf of, and are not intended to confer rights or
remedies upon LDDS, any security-holder of IDB or LDDS, or any person other than
IDB's Board of Directors. Except as required by applicable law, including
without limitation federal securities laws, our opinion may not be published or
otherwise used or referred to, nor shall any public reference to Hambrecht &
Quist be made, without our prior consent.
 
     Based upon and subject to the foregoing and after considering such other
matters as we deem relevant, we are of the opinion that as of the date hereof
the consideration to be received by the holders of the Common Stock in the
Proposed Transaction is fair to such holders from a financial point of view. We
express no opinion, however, as to the adequacy of any consideration received in
the Proposed Transaction by LDDS or any of its affiliates.
 
                                          Very truly yours,

IDB Communications Group, Inc.
10525 West Washington Boulevard
Culver City, California
 
Attention: Board of Directors
 
Gentlemen:
 
     IDB Communications Group, Inc. ("IDB"), LDDS Communications, Inc. ("LDDS"),
and 123 Corp., a wholly-owned subsidiary of LDDS, have entered into an Agreement
and Plan of Merger, dated as of August 1, 1994 (the "Merger Agreement"),
providing for, among other things, the merger of 123 Corp. with and into IDB
(the "Merger"). As more specifically set forth in the Merger Agreement, at the
effective time of the Merger, the outstanding shares of common stock, par value
$0.01 per share, of IDB (the "IDB Common Stock") shall be converted into shares
of the common stock, par value $0.01 per share, of LDDS (the "LDDS Common
Stock"), pursuant to the exchange formula provided for in the Merger Agreement
(the "Exchange Ratio"). For purposes of this opinion, we have assumed the Merger
will be tax-free to IDB, LDDS, and their respective shareholders and will be
accounted for as a pooling of interests. On August 22, 1994, LDDS announced that
it had signed a definitive agreement (the "WilTel Agreement") with The Williams
Companies, Inc. ("Williams") to acquire the WilTel Network Services operations
("WilTel") of William's subsidiary, Williams Telecommunications Group, Inc., for
$2.5 billion in cash, subject to adjustment (the "WilTel Acquisition"). We
understand that the WilTel Acquisition is not a condition to the consummation of
the Merger.
 
     In light of the proposed WilTel Acquisition, you have requested us to
reconfirm our prior opinion as to the fairness, from a financial point of view,
to the holders of the IDB Common Stock of the Exchange Ratio in the Merger
whether or not the WilTel Acquisition is consummated.
 
     In arriving at the opinion set forth below, we have, among other things,
reviewed or analyzed:
 
          (a) the Merger Agreement, the WilTel Agreement and the Schedule 14A,
     including the Preliminary Joint Proxy Statement, relating to the Merger as
     filed with the Securities and Exchange Commission on September 12, 1994;
 
          (b) certain publicly available financial information of IDB, LDDS and
     Williams, including the Annual Report on Form 10-K of each IDB, LDDS and
     Williams for the fiscal year ended December 31, 1993 and the Quarterly
     Report on Form 10-Q of each of IDB, LDDS and Williams for the quarter ended
     June 30, 1994;
 
          (c) certain other publicly available financial and other information
     that we deemed relevant concerning IDB, LDDS and WilTel and the industries
     in which they operate, including the combined audited financial statements
     for WilTel for the three years ended December 31, 1993;
 
          (d) the reported prices and trading history of the IDB Common Stock
     and LDDS Common Stock, and compared certain financial and stock market
     information for IDB and LDDS with each other and with similar information
     for certain other companies with publicly traded securities;
 
                                       D-1
<PAGE>   174
 
          (e) certain internal financial and operating data of IDB and LDDS
     (with and without WilTel), including management forecasts, and certain pro
     forma combined information giving effect to the Merger and the WilTel
     Acquisition;
 
          (f) the business prospects of IDB and LDDS (with and without WilTel)
     before and after giving effect to the Merger, with senior management of
     IDB, LDDS and WilTel;
 
          (g) a comparison of the financial and operating performance of IDB and
     LDDS (with and without WilTel) with each other and with certain other
     companies deemed comparable;
 
          (h) the terms of the Certificates of Incorporation and Bylaws of IDB
     and LDDS as in effect prior to the effective time of the Merger, the other
     documents defining the rights of securityholders of IDB and LDDS, and the
     forms of such Certificates, Bylaws and documents as they shall be in effect
     at and after the effective time of the Merger;
 
          (i) the nature and terms of certain recent transactions which we
     believe to be reasonably comparable to the Merger or otherwise relevant to
     our inquiry;
 
          (j) certain publicly available information regarding certain other
     companies that we believe to be comparable to IDB and LDDS (with and
     without WilTel) and the trading markets for certain of such other
     companies' securities; and
 
          (k) certain other analyses and examinations as we have deemed
     necessary or appropriate.
 
     We have assumed and relied upon without independent verification the
accuracy and completeness of all of the financial and other information provided
to, discussed with, or reviewed by or for us, or publicly available for purposes
of this opinion. We have neither made nor obtained any independent evaluations
or appraisals of the assets or liabilities of IDB or LDDS (with or without
WilTel), nor have we conducted a physical inspection of the properties and
facilities of IDB, LDDS or WilTel. We have assumed that the financial
projections of IDB and LDDS (with and without WilTel) have been reasonably
prepared on bases reflecting the best currently available estimates and
judgments of the respective management of each of IDB, LDDS and WilTel as to the
future financial performance of IDB or LDDS (with and without WilTel) as the
case may be, and have relied upon the judgments of the respective managements of
IDB, LDDS and WilTel as to the estimated cost savings and synergies resulting
from the combination of IDB and LDDS (with and without WilTel). We express no
view as to such projections or estimates or the assumptions on which they were
based. We were not requested to, and did not, participate in the negotiations
relating to the Merger or the WilTel Acquisition or solicit third party
indications of interest in acquiring any or all of IDB's assets, properties or
securities.
 
     In rendering our opinion we have assumed, with your consent, that in the
course of obtaining any necessary consents and approvals, or any amendments,
modifications or waivers to any documents to which either of IDB, LDDS or WilTel
are party, as contemplated by the Merger Agreement or the WilTel Agreement, no
restrictions will be imposed or amendments, modifications or waivers made that
would have any adverse effect on the contemplated benefits to the holders of IDB
Common Stock following the Merger.
 
     Our opinion herein is necessarily based on market, economic and other
conditions as they exist and can be evaluated on the date of this letter.
Furthermore, in rendering our opinion we have not taken into account any future
agreement which LDDS might enter into prior to consummation of the Merger to
effect a material acquisition transaction other than the WilTel Acquisition. Our
opinion is limited to the fairness, from a financial point of view, of the
Exchange Ratio to the holders of the IDB Common Stock, and we express no opinion
as to the merits of IDB's decision to participate in the Merger. This opinion
does not constitute a recommendation to any IDB stockholder as to how the
stockholder should vote with respect to the Merger.

continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions and valuations for estate, corporate

management services, to certain officers or directors of IDB and LDDS, as well
as providing general commercial banking services to companies in which they have
a financial interest or for which they serve as an officer, director or
employee. Chemical Bank and its affiliates, including Chemical Securities Inc.,
have provided, and in the future may provide, commercial and investment banking
services to Williams. In the ordinary course of business, we or our affiliates
may trade in the debt and equity securities of IDB, LDDS and Williams for our
own accounts and for the accounts of our customers and, accordingly, may at any
time hold a long or short position in such securities.
 
     The opinion expressed herein is provided solely for the use of the Board of
Directors of IDB in its evaluation of the Merger and is not intended to be
relied upon or to confer rights or remedies upon LDDS or any stockholder of IDB
or LDDS. Except as required by applicable law, including without limitation
federal securities laws, our opinion may not be published or otherwise used or
referred to, nor shall any public reference to Chemical Securities Inc. be made,
without our prior consent.
 
     Based upon and subject to the foregoing, and such other matters as we
consider relevant, we are of the opinion, as of the date hereof, that the
Exchange Ratio is fair, from a financial point of view, to the holders of IDB
Common Stock, whether or not the WilTel Acquisition is consummated.

                           LDDS COMMUNICATIONS, INC.
                      1995 SPECIAL PERFORMANCE BONUS PLAN
 
I. PURPOSE.
 
     The LDDS Communications, Inc. Special Performance Bonus Plan (the "Plan")
is established to provide a special bonus for the Chief Executive Officer (the
"Participant") of LDDS Communications, Inc. (the "Company") with respect to
fiscal year 1995. Any such bonus shall be in addition to any other bonus payable
to the Participant. The efficacy of this Plan and the payment of any bonus
hereunder are expressly contingent on approval of the Plan by the shareholders
of the Company.
 
II. ADMINISTRATION; ELIGIBILITY.
 
     The Plan is administered by the Compensation and Stock Option Committee of
the Company, such other committee as may be designated by the Board of Directors
of the Company or a subcommittee of the committee involved as may be designated
by said committee (hereinafter such committee or subcommittee, as applicable, is
referred to as the "Committee"). The Committee shall be comprised solely of two
or more outside directors of the Company (as defined in Section 162(m)(4)(C)(i)
of the Internal Revenue Code of 1986, as amended, and the regulations
thereunder). The Committee, subject to the approval of the full Board of
Directors, has complete discretion and authority with respect to the Plan and
its application. The Participant is the only employee eligible to participate in
the Plan.
 
III. DETERMINATION OF BONUS.
 
     The award of a bonus to the Participant under the Plan is predicated on the
achievement by the Company of one or more performance goals during fiscal year
1995, as determined by the Committee. Prior to December 31, 1994, the Committee
shall establish in writing (a) a maximum bonus under the Plan for the
Participant, which shall not exceed $1,000,000, and (b) one or more performance
goals which must be met as a precondition to the payment of a bonus. Such
goal(s) shall be based on gross revenues of the Company.
 
     The Committee shall convene as and when appropriate to determine whether,
in fact, the previously established performance goal(s) has/have been met. The
Committee shall certify in writing to the full Board of Directors whether the
performance goal(s) has/have been met prior to payment of any bonus.
 
     If the Committee determines that the performance goal(s) has/have been met,
the Participant may receive a bonus under the Plan which shall not exceed the
maximum amount established by the Committee.
 
     All determinations of revenues shall be derived from the regularly prepared
financial statements of the Company.
 
IV. AMOUNT AND DISTRIBUTION OF THE BONUS.
 
     After certifying that the performance goal or goals has or have been met,
the Committee will then decide whether the Participant will receive his maximum
bonus under the Plan or some lesser amount (or no bonus at all). Except as
otherwise provided herein, the Committee's decision regarding the amount of the
Participant's bonus shall be made in the sole discretion of the Committee.
 
     Distribution of the bonus determined under the preceding paragraph shall be
made as soon as practicable after the Committee's certification described in
Article III, above. Any bonus hereunder shall be payable in cash.
 
V. MISCELLANEOUS PROVISIONS.
 
     1. Nothing contained herein will confer upon the Participant the right to
be retained in the service of the Company or any subsidiary thereof nor limit
the right of the Company or any subsidiary thereof to discharge
 
                                       E-1
<PAGE>   177
 
or otherwise deal with the Participant without regard to the existence of the
Plan.
 
     2. The Plan shall at all times be entirely unfunded and no provision shall
at any time be made with respect to segregating assets of the Company or any
subsidiary thereof for payment of any bonus hereunder. Neither the Participant
nor any other person shall have any interest in any particular assets of the
Company or any subsidiary thereof by reason of the right to receive a bonus
under the Plan and the Participant and any other person shall have only the
rights of a general unsecured creditor of the Company or any subsidiary thereof
with respect to any rights under the Plan.
 
     3. This Plan shall be binding upon and inure to the benefit of the Company
and its successors and assigns.
 
     4. This Plan, and the rights and obligations of the parties hereunder,
shall be governed by and construed in accordance with the internal laws of the
State of Mississippi.
 
     5. The Company reserves the right to terminate the Plan in its entirety at
any time, with or without notice, or to amend the Plan as it exists from time to
time, with or without notice, through resolution of the Committee.
 
     IN WITNESS WHEREOF, the Compensation and Stock Option Committee of the
Company has adopted this Plan as of July 1, 1994.

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Section 14-2-202(b)(4) of the Georgia Business Corporation Code (the
"Georgia Code") provides that a corporation's articles of incorporation may
include a provision that eliminates or limits the personal liability of
directors for monetary damages to the corporation or its shareholders for breach
of their duty of care and other duties as directors; provided, however, that the
Section does not permit a corporation to eliminate or limit the liability of a
director for appropriating, in violation of his duties, any business opportunity
of the corporation, engaging in intentional misconduct or a knowing violation of
law, obtaining an improper personal benefit, or voting for or assenting to an
unlawful distribution (whether as a dividend, stock repurchase or redemption, or
otherwise) as provided in Section 14-2-832 of the Georgia Code. Section
14-2-202(b)(4) also does not eliminate or limit the rights of LDDS or any
shareholder to seek an injunction or other nonmonetary relief in the event of a
breach of a director's duty to the corporation and its shareholders.
Additionally, Section 14-2-202(b)(4) applies only to claims against a director
arising out of his role as a director, and does not relieve a director from
liability arising from his role as an officer or in any other capacity.
 
     The provisions of Article Nine of LDDS's Amended and Restated Articles of
Incorporation are similar in all substantive respects to those contained in
Section 14-2-202(b)(4) of the Georgia Code as outlined above. Article Nine
further provides that the liability of directors of LDDS shall be limited to the
fullest extent permitted by amendments to Georgia law.
 
     Sections 14-2-850 to 14-2-859, inclusive, of the Georgia Code govern the
indemnification of directors, officers, employees, and agents. Section 14-2-851
of the Georgia Code permits indemnification of a director of LDDS for liability
incurred by him in connection with any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(including, subject to certain limitations, civil actions brought as derivative
actions by or in the right of LDDS) in which he is made a party by reason of
being a director of LDDS and for directors who, at the request of LDDS, act as
directors, officers, partners, trustees, employees or agents of another foreign
or domestic corporation, partnership, joint venture, trust, employee benefit
plan or other enterprise. The Section permits indemnification if the director
acted in a manner he believed in good faith to be in or not opposed to the best
interest of LDDS and, in addition, in criminal proceedings, if he had no
reasonable cause to believe his conduct was unlawful. If the required standard
of conduct is met, indemnification may include judgments, settlements,
penalties, fines or reasonable expenses (including attorneys' fees) incurred
with respect to a proceeding. However, if the director is adjudged liable to
LDDS in a derivative action or on the basis that personal benefit was improperly
received by him, the director is not entitled to indemnification by the
corporation; provided that the director may be entitled to indemnification for
reasonable expenses as determined by a court in accordance with the provisions
of Section 14-2-854, or unless LDDS's Amended and Restated Articles of
Incorporation or Bylaws, or a contract or resolutions approved by LDDS's
shareholders pursuant to Section 14-2-856, authorizes indemnification.
 
     Section 14-2-852 of the Georgia Code provides that unless limited by the
articles of incorporation, directors who are successful with respect to any
claim brought against them, which claim is brought because they are or were
directors of LDDS, are entitled to mandatory indemnification against reasonable
expenses incurred in connection therewith. Conversely, if the charges made in
any action are sustained, the determination of whether the required standard of
conduct has been met will be made, in accordance with the provisions of Section
14-2-855 of the Georgia Code, as follows: (i) by the majority vote of a quorum
of the members of the board of directors not a party to such action at that
time, (ii) if a quorum cannot be obtained, by a committee thereof duly
designated by the board of directors, consisting of two or more directors not a
party to such action at that time, (iii) by duly selected special legal counsel,
or (iv) by the shareholders, but, in such event, the shares owned by or voted
under the control of directors who are at the time parties to the proceeding may
not be voted.
 
                                      II-1
<PAGE>   179
 
     Section 14-2-857 of the Georgia Code provides that an officer of LDDS (but
not an employee or agent generally) who is not a director has the mandatory
right of indemnification granted to directors under Section 14-2-852, as
described above. In addition, LDDS may, as provided by LDDS's Amended and
Restated Articles of Incorporation, Bylaws, general or specific actions by its
board of directors, or by contract, indemnify and advance expenses to an
officer, employee or agent who is not a director to the extent that such
indemnification is consistent with public policy.
 
     The indemnification provisions of Article X of LDDS's Bylaws and Article
Eleven of LDDS's Amended and Restated Articles of Incorporation are consistent
with the foregoing provisions of the Georgia Code. However, LDDS's Amended and
Restated Articles of Incorporation prohibit indemnification of a director who
did not believe in good faith that his actions were in, or not contrary to,
LDDS's best interests. LDDS's Bylaws extend the indemnification available to
officers under the Georgia Code to employees and agents.

ITEM 21(B). FINANCIAL STATEMENT SCHEDULES.
 
     All financial statement schedules of LDDS and IDB which are required to be
included herein are included in the Annual Report of LDDS on Form 10-K for the
fiscal year ended December 31, 1993 or the Annual Report of IDB on Form 10-K for

ITEM 22. UNDERTAKINGS.
 
     (1) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 (the "Act") may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question of whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.
 
     (2) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Act, each filing of the registrant's annual
report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act
of 1934 (the "Exchange Act") (and, where applicable, each filing of an employee
benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that
is incorporated by reference in the registration statement shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
     (3) The undersigned registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.
 
     (4) The registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (3) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415 under the Act, will be filed as a
part of an
 
                                      II-2
<PAGE>   180
 
amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offering therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
     (5) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11 or 13 of this form, within one business day of receipt of such
request, and to send the incorporated documents by first class mail or other
equally prompt means. This includes information contained in documents filed
subsequent to the effective date of the registration statement through the date
of responding to the request.
 
     (6) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.
 
     (7) The undersigned registrant hereby undertakes:
 
          (a) To file, during any period in which offers and sales are being
     made, a post-effective amendment to this registration statement:
 
             (i) To include any prospectus required by Section 10(a)(3) of the
        Act;
 
             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the Registration Statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement;
 
             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement;
 
          (b) That for the purposes of determining any liability under the Act,
     each such post-effective amendment shall be deemed to be a new registration
     statement relating to the securities offered therein, and the offering of
     such securities at that time shall be deemed to be the initial bona fide
     offering thereof.
 
          (c) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.

Board of Directors of
  LDDS Communications, Inc.
515 East Amite Street
Jackson, Mississippi 39201
 
Ladies and Gentlemen:
 
     We have acted as special counsel for LDDS Communications, Inc., a Georgia
corporation (the "Company"), in connection with a Registration Statement on Form
S-4 (the "Registration Statement") to be filed by the Company with the
Securities and Exchange Commission (the "Commission") under the Securities Act
of 1933, as amended, with respect to the proposed issuance of a maximum of
45,925,726 shares (the "Shares") of common stock, par value $.01, of the Company
("Common Stock") to the stockholders of IDB Communications Group, Inc., a
Delaware corporation ("IDB"), pursuant to the Agreement and Plan of Merger dated
as of August 1, 1994, by and among the Company, 123 Corp., a Delaware
corporation wholly owned by the Company, and IDB (the "Merger Agreement").
 
     In connection herewith, we have examined and relied without investigation
as to matters of fact upon the Registration Statement and the Joint Proxy
Statement/Prospectus included as part thereof, the Amended and Restated Articles
of Incorporation and Bylaws of the Company, certificates of public officials,
certificates and statements of officers of the Company, and such other corporate
records, documents, certificates and instruments as we have deemed necessary or
appropriate to enable us to render the opinions expressed herein. We have
assumed the genuineness of all signatures on all documents examined by us, the
authenticity of all documents submitted to us as originals, and the conformity
to authentic originals of all documents submitted to us as certified or
photostatic copies. We have also assumed the due authorization, execution and
delivery of all documents.
 
     Based upon the foregoing, and in reliance thereon and subject to the
qualifications and limitations stated herein, we are of the following opinions:
 
     1. The Company is a corporation validly existing under the laws of the
        State of Georgia; and
 
     2. When the Registration Statement, including any amendments thereto, shall
        have become effective under the Act, and the Shares have been issued in
        accordance with the terms of the Merger Agreement, then the Shares will
        be legally issued, fully paid and nonassessable.
 
     This opinion is not rendered with respect to any laws other than the latest
codification of the Georgia Business Corporation Code (the "GBCC") available to
us. We note that the Merger Agreement provides that it is governed by and is to
be construed and interpreted in accordance with the internal laws of the State
of Delaware but, in rendering the opinions expressed herein, we have assumed
that such matters are governed exclusively by the GBCC and we express no opinion
as to which law any court construing the Merger Agreement would apply. This
opinion has not been prepared by attorneys admitted to practice in Georgia or
Delaware.
 
     We hereby consent to the filing of this opinion as Exhibit 5.1 to the
aforesaid Registration Statement on Form S-4 and to the use of our name under
the caption "Legal Matters" in the Prospectus filed as part thereof. We also
consent to your filing copies of this opinion as an exhibit to the Registration
Statement with agencies of such states as you deem necessary in the course of
complying with the laws of such states regarding the offering and sale of the
Shares. In giving this consent, we do not admit that we are in the category of
persons whose consent is required under Section 7 of the Act or the rules and
regulations of the Commission.
 
                                         Very truly yours,
 
                                         /s/  BRYAN CAVE

          Re: Registration Statement on Form S-4 of
              LDDS Communications, Inc.
 
Dear Sir or Madam:
 
     This opinion is delivered to you in connection with the preparation of the
Registration Statement on Form S-4 to be filed with the Securities and Exchange
Commission by LDDS Communications, Inc. ("LDDS") in connection with the proposed
merger (the "Merger") of a wholly owned subsidiary of LDDS with and into IDB
Communications Group, Inc. ("IDB"). We have reviewed both the applicable
disclosure requirements under the federal securities laws and the tax disclosure
set forth in the Joint Proxy Statement/Prospectus which is included in the
Registration Statement (the "Joint Proxy Statement"). In our opinion, the
statements contained in the Joint Proxy Statement under the heading "PLAN OF
MERGER -- Certain Federal Income Tax Consequences" fairly and accurately present
the information required to be presented.
 
     This letter is furnished by us as counsel for IDB and is solely for the
benefit of IDB.
 
     This opinion is based on current authorities and upon facts and assumptions
as of this date. It is subject to change in the event of a change in the
applicable law or a change in the interpretation of such law by the courts or by
the Internal Revenue Service. There can be no assurance that legislative or
administrative changes or court decisions will not be forthcoming that would
significantly modify this opinion. Any such changes may or may not be
retroactive with respect to transactions prior to the date of such changes. This
opinion has no binding effect or official status, and accordingly no assurance
can be given that the position set forth herein will be sustained by a court, if
contested. No ruling will be obtained from the Internal Revenue Service with
respect to the Merger.
 
     We consent to the filing of this opinion as an exhibit to the Registration
Statement and to the use of our name under the caption "Legal Matters" in the
Registration Statement and the Joint Proxy Statement which forms a part thereof.
 
                                            Respectfully submitted,
 
                                            /s/  O'MELVENY & MYERS
