                                PROXY STATEMENT
                         ANNUAL MEETING OF STOCKHOLDERS
                                  MAY 25, 1999
 
                SOLICITATION, VOTING AND REVOCABILITY OF PROXIES
 
     This Proxy Statement and the accompanying Notice of Annual Meeting and form
of Revocable Proxy are being furnished, on or about April 30, 1999, to the
stockholders of LCC International, Inc. (the "Company"), in connection with the
solicitation of proxies by the Board of Directors of the Company to be used at
the 1999 Annual Meeting of Stockholders of the Company (the "Annual Meeting") to
be held on Tuesday, May 25, 1999 at 10:00 a.m. (eastern daylight time) at the
offices of LCC International, Inc., 7925 Jones Branch Drive, McLean, Virginia,
22102, and any adjournment thereof.
 
     The purpose of the Annual Meeting is (i) to elect the Board of Directors,
which consists of five members; (ii) to ratify the appointment of KPMG LLP as
the Company's independent auditors for the fiscal year ending December 31, 1999;
and (iii) to transact such other business as may properly come before the Annual
Meeting or any adjournments thereof.
 
     If the enclosed form of proxy is properly executed and returned to the
Company in time to be voted at the Annual Meeting, the shares represented
thereby will be voted in accordance with the instructions thereon. EXECUTED BUT
UNMARKED PROXIES WILL BE VOTED: (i) FOR THE ELECTION OF FIVE DIRECTORS TO THE
BOARD OF DIRECTORS; AND (ii) FOR THE RATIFICATION OF THE APPOINTMENT OF KPMG LLP
AS THE COMPANY'S INDEPENDENT AUDITORS. If any other matters are properly brought
before the Annual Meeting, proxies will be voted in the discretion of the proxy
holders. The Company is not aware of any such matters that are proposed to be
presented at its Annual Meeting.
 
     The cost of soliciting proxies in the form enclosed herewith will be borne
entirely by the Company. The Company has retained D.F. King & Co., Inc. to
solicit proxies on its behalf for a fee of approximately $3,500. In addition,
proxies may be solicited by directors, officers and regular employees of the
Company, without extra remuneration, by personal interviews, telephone,
telegraph or otherwise. The Company will request persons, firms and corporations
holding shares in their name or in the names of their nominees, which are
beneficially owned by others, to send proxy materials to and obtain proxies from
the beneficial owners and will reimburse the holders for their reasonable
expenses in doing so.
 
     The securities which can be voted at the Annual Meeting consist of shares
of Class A Common Stock, par value $.01 ("Class A Common Stock"), and Class B
Common Stock, par value $.01 ("Class B Common Stock" and together with the Class
A Common Stock, the "Common Stock"), of the Company. Each outstanding share of
Class A Common Stock entitles its owner to one vote on each matter as to which a
vote is taken at the Annual Meeting. Each outstanding share of Class B Common
Stock entitles its owner to ten votes on each matter as to which a vote is taken
at the Annual Meeting. The close of business on March 30, 1999 has been fixed by
the Board of Directors as the record date (the "Record Date") for determination
of stockholders entitled to vote at the Annual Meeting. The number of shares of
Class A Common Stock and Class B Common Stock outstanding and entitled to vote
on the Record Date was 7,200,648 and 8,460,984, respectively. The presence, in
person or by proxy, of shares of Common Stock issued and outstanding and
constituting at least a majority of the votes entitled to vote on the Record
Date is necessary to constitute a quorum at the Annual Meeting. Stockholders'
votes will be tabulated by the Company's Secretary and Controller, who have been
appointed by the Board of Directors to act as inspectors of election for the
Annual Meeting. Under Delaware corporate law and the Company's Amended and
Restated Bylaws (the "Bylaws"), directors are elected by a plurality of votes
cast by the shares present (in person or by proxy) and entitled to vote. Unless
otherwise required by law or the Company's Restated Certificate of Incorporation
or Bylaws, any other matter put to a stockholder vote will be decided by the
affirmative vote of a majority of the votes cast on
<PAGE>   5
 
the matter. Abstentions and broker non-votes are not included as votes cast and
accordingly will be excluded from the total number of votes upon which a
majority is based. Thus, votes to abstain and broker non-votes will have no
effect on the vote tabulation for such proposals.
 
     The presence of a stockholder at the Annual Meeting will not automatically
revoke the stockholder's proxy. However, a stockholder may revoke a proxy at any
time prior to its exercise by filing with the Secretary of the Company a written
notice of revocation, by delivering to the Company a duly executed proxy bearing
a later date or by attending the Annual Meeting and voting in person.
 
                            ------------------------
 
          THE BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE FOR
          APPROVAL OF THE PROPOSALS SET FORTH IN THIS PROXY STATEMENT.
 
                            ------------------------
 
              CERTAIN BACKGROUND INFORMATION REGARDING THE COMPANY
 
     The Company's business commenced in 1983 in a corporation named LCC
Incorporated (presently named Cherrywood Holdings, Inc. ("Cherrywood")), a
Kansas corporation organized in 1983 and wholly owned by Dr. Rajendra and Neera
Singh and certain Singh family trusts. In 1994 Cherrywood transferred the
business to Telcom Ventures, L.L.C. ("Telcom Ventures"), a Delaware limited
liability company, for a 75% interest in Telcom Ventures. At the same time,
certain entities formed by The Carlyle Group, a Washington, D.C.-based
investment group (the "Carlyle Investors"), acquired a 25% interest in Telcom
Ventures in consideration of a cash contribution. Telcom Ventures then formed
LCC, L.L.C. (the "Limited Liability Company"), a Delaware limited liability
company, and transferred the business to the Limited Liability Company in
exchange for a 99% interest in the Limited Liability Company. Cherrywood and TC
Group, L.L.C., an affiliate of the Carlyle Investors ("TC Group"), received
direct interests of 0.75% and 0.25%, respectively, in the Limited Liability
Company. LCC International, Inc. was formed in June 1996 for the purpose of
effecting an initial public offering of equity securities which was accomplished
by the merger of the Limited Liability Company with and into LCC International,
Inc. (the "Merger") in connection with the initial public offering of LCC
International, Inc.'s Class A Common Stock (the "Offering"). Prior to the
Merger, Telcom Ventures transferred its interest in the Limited Liability
Company to RF Investors, L.L.C. ("RF Investors"), a Delaware limited liability
company of which Telcom Ventures owns 99% and Cherrywood and TC Group own 0.75%
and 0.25%, respectively. Since the Offering, Cherrywood and TC Group have
transferred to RF Investors the shares of the Company which they received as a
result of the Merger.
 
     Unless the context indicates or requires otherwise, references in this
Proxy Statement to the "Company" are to its predecessor entities and their
respective subsidiaries prior to the Merger and to LCC International, Inc. and
its subsidiaries after the Merger.

                      BENEFICIAL OWNERSHIP OF COMMON STOCK
 
     The following table sets forth certain information regarding beneficial
ownership of the Company's Common Stock as of March 23, 1999 by (i) each
director (and director nominee), (ii) the Chief Executive Officers that served
during 1998, each of the other four most highly compensated executive officers
whose total annual salary and bonus exceeded $100,000 during the year ended
December 31, 1998, and two other individuals who would have been among the four
most highly compensated executive officers whose total annual salary and bonus
exceeded $100,000 during the year ended December 31, 1998 except that they were
not serving as an executive officer at the end of fiscal year 1998 (the "Named
Executive Officers"), (iii) all persons known to the Company to be beneficial
owners of more than 5% of its outstanding Class A or Class B Common Stock and
(iv) all directors and executive officers as a group. This information is based
upon the most recent filing made by such persons with the Securities and
Exchange Commission (the "Commission") or information provided to the Company by
such persons. Under the rules of the Commission, a person is deemed a
"beneficial owner" of a security if such person has or shares the power to vote
or direct the voting of such security or the power to dispose or direct the
disposition of such security. A person is also deemed to be a beneficial owner
of any securities of which that person has the right to acquire beneficial
ownership within 60 days. More than one person may be deemed to be a beneficial
owner of the same securities.

beneficially owning more than 10% of the outstanding Class A Common Stock). The
option exercise price for non-incentive stock options granted under the Employee
Plan may not be less than the par value of the Class A Common Stock on the date
of grant of the option. The maximum option term is 10 years (or five years in
the case of an incentive stock option granted to an optionee beneficially owning
more than 10% of the outstanding Class A Common Stock). Options may be exercised
at any time after grant, except as otherwise provided in the particular option
agreement. There is also a $100,000 limit on the value of Class A Common Stock

  Report on Option Repricing
 
     On December 11, 1998 the Compensation and Stock Option Committee determined
that, as result of declines in the market price of the Class A Common Stock,
many employees, including the Company's executives, held options at prices that
limited their effectiveness as a tool for employee retention and as a long-term
incentive. After considering the matter, the committee voted to decrease to
$5.00 the per share exercise price of all outstanding options under the Employee
Plan having a per share exercise price in excess of $5.00 (except for options
for to purchase an aggregate of 328,650 shares held by seven (7) individuals,
including Dr. Carroll). The closing price of the Class A Common Stock on the
Nasdaq National Market on the day preceding the repricing was $3.63. All other
terms of these options remain unchanged.
 
     The repricing affected outstanding options to purchase 887,000 shares,
including options to purchase 62,000 shares, 77,500 shares, 18,334 shares and
50,000 shares held by Messrs. Bonin, Deliso, Lawson and McNelly, respectively,
and options to purchase 20,000 shares held by Mr. Ein.

EMPLOYMENT AGREEMENTS
 
     Dr. Geoffrey S. Carroll.  Effective October 5, 1998, Dr. Geoffrey S.
Carroll resigned from his position as President and Chief Executive Officer of
the Company. Pursuant to an agreement entered into by Dr. Carroll and the
Company on that date, which supersedes Dr. Carroll's then-existing employment
agreement with the Company (the "Resignation Agreement"), Dr. Carroll performs
advisory services for the Company as requested by the Chairperson of the Company
from time to time. The term of the Resignation Agreement is one year and the
Company will pay Dr. Carroll the aggregate amount of $400,000 (the "Advisory
Service Fee"), plus reimbursement of reasonable out-of-pocket expenses, for his
advisory services. In the event of termination of Dr. Carroll's services as a
result of his death, his disability, termination by the Company for cause or
termination by Dr. Carroll, the Company is obligated to pay the portion of the
Advisory Service Fee which accrued through the date of such termination. In the
event of termination of Dr. Carroll's services without cause, the Company is
obligated to pay the Advisory Service Fee through the earlier of October 5, 1999
or the date on which Dr. Carroll commences other employment.
 
     Dr. Carroll is not entitled to participate in any of the Company's benefit
plans, except with the respect to the stock options described below. Dr.
Carroll, in turn, has agreed to reimburse the Company for certain expenses paid
on his behalf during his employment and has assumed the remaining obligations
under an apartment lease entered into by the Company on his behalf. In addition,
among other things, Dr. Carroll is obligated to maintain the confidentiality of
all confidential information of the Company disclosed to him and, subject to
certain exceptions, to refrain from competing with the Company until October 5,
1999.
 
     Pursuant to the Resignation Agreement, the options granted to Dr. Carroll
under the Employee Plan at the time he commenced his employment with the Company
were terminated except as to an option to purchase up to 90,000 shares of Class
A Common Stock at a per share exercise price of $12.625 and an option to
purchase up to 105,000 shares of Class A Common Stock at a per share exercise
price of $18.84. The foregoing options are exercisable currently and will expire
on October 5, 1999. Under his former employment agreement and related stock
option agreement with the Company, Dr. Carroll was granted ten-year options
under the Employee Plan to purchase (i) up to 450,000 shares of Class A Common
Stock at a per share exercise price of $12.65 and (ii) up to an additional
525,000 shares of Class A Common Stock divided into five equal series of 105,000
shares with increasing per share exercise prices, with the first series at
$18.84, the second series at $21.85, the third series at $25.35, the fourth
series at $29.40 and the fifth series at $34.10. All of the foregoing options
would have expired on January 15, 2008, subject to earlier expiration in certain
circumstances.
 
COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION
 
     On May 20, 1997, the Board of Directors adopted the following compensation
policy prepared by the Compensation Committee:
 
                         EXECUTIVE COMPENSATION POLICY
 
  Policy Purpose
 
     To facilitate the recruitment, retention and motivation of the President
and Chief Executive Officer, the Senior Vice Presidents, the Vice Presidents and
such other persons the determination of whose compensation the Board of
Directors shall determine (each of the foregoing, an "Executive") will be
covered by this policy (the "Executive Compensation Policy") in ways consistent
with the enhancement of shareholder value, service quality and employee
satisfaction.
 
  Compensation Elements
 
     Executive compensation includes four principal elements: (i) base salary;
(ii) employee benefits; (iii) annual incentive compensation; and (iv) equity
participation (the "Principal Elements").
 
                                       17
<PAGE>   21
 
  Criteria for Determination of Executive Compensation
 
     In determining each of the Principal Elements of each Executive's
compensation, as well as the overall compensation package thereof; the following
criteria shall be considered by the persons responsible for recommending or
approving such compensation (each a "Reviewer"): (i) the compensation awarded to
executives with comparable titles and responsibilities to those of such
Executive by companies in the wireless telecommunications industry (or, to the
extent information is not available, in comparable industries) whose revenues
and earnings are comparable to those of the Company (the "Comparable
Companies"), as reported by reliable independent sources; (ii) the results of
operations of the Company during the past year, on an absolute basis and
compared with the Company's targeted results for such year as well as with the
results of the Comparable Companies, as reported by reliable independent
sources; (iii) the performance of such Executive during the past year, on an
absolute basis and as compared with the performance targets set by the Company
for such Executive for such year and the performance of the other Executives of
the Company during such year and (iv) any other factor which the Reviewers
determine to be relevant. The weight to be given to each of the foregoing
criteria shall be determined by the Reviewers in the exercise of reasonable
judgment in accordance with the purposes of this Executive Compensation Policy
and may vary from time to time or from Executive to Executive.
 
     Also at its May 20, 1997 meeting, the Board of Directors adopted
implementation guidelines with respect to the Executive Compensation Policy. In
particular, on an annual basis, the Compensation Committee reviews the
compensation paid to the President and Chief Executive Officer of the Company
and, taking into account each factor set forth in the Executive Compensation
Policy set forth above, submits to the Board of Directors its recommendation
regarding the compensation to be paid to the President and Chief Executive
Officer following a review of such recommendation, the Board of Directors will
take such action regarding such compensation, consistent with the Executive
Compensation Policy as it deems appropriate. With regard to the compensation
paid to each Executive other than the President and Chief Executive Officer, the
Board empowered the President and Chief Executive Officer to review, on an
annual basis, the compensation paid to each Executive during the past year and,
taking account each factor set forth in the Executive Compensation Policy, and
to submit to the Board of Directors his recommendations regarding the
compensation to be paid to such persons during the next year and following a
review of such recommendations, the Compensation Committee will take such action
regarding such compensation, consistent with the Executive Compensation Policy,
as it deems appropriate.
 
     Compensation arrangements during the Company's 1998 fiscal year were
determined in accordance with the Executive Compensation Policy and the May 20,
1997 Board of Directors' implementation guidelines, except that Dr. Rajendra
Singh, the Company's Interim President and Chief Executive Officer, has agreed
to serve in such capacity without compensation.

family and certain family trusts beneficially owned 75% of the outstanding
interests in Telcom Ventures.

  Corporate Opportunity
 
     Concurrently with the Offering, the Company and Telcom Ventures, RF
Investors, Cherrywood, Dr. Rajendra Singh, Neera Singh, certain Singh family
trusts (the five immediately foregoing persons and entities being collectively
referred to as the "Singh Family Group") and the Carlyle Investors (all of the
foregoing, together with their respective successors or members of their
immediate family, the "Telcom Ventures Group") entered into an Intercompany
Agreement. Under the Intercompany Agreement, Telcom Ventures, RF Investors,
Cherrywood and the Singh Family Group have agreed that, until the earlier of (i)
the date on which the Telcom Ventures Group no longer possesses voting control
of the Company or (ii) the occurrence of certain termination events specified in
the 1993 Formation Agreement among the members of the Telcom Ventures Group (the
"Formation Agreement"), none of them will, directly or indirectly, participate
or engage, other than through the Company, in any of the Company's traditional
business activities, defined as (i) the provision of cellular radio frequency
engineering and network design services to the wireless telecommunications
industry, (ii) the provision of program management services or deployment or
construction related consulting services to the wireless telecommunications
industry and (iii) the manufacture, sale, license, distribution or servicing of
any radio network planning software tools or drive test field measurement and
analysis equipment which are used by the Company in connection with the Company
services described in the foregoing clauses (i) or (ii). The foregoing
prohibition does not apply to services provided to third parties in which any
member of the Telcom Ventures Group holds or is considering the acquisition of
an investment where the provision of services is incidental to such member's
investment or to the ownership by any member of the Telcom Ventures Group of up
to 5% of the outstanding securities of any entity as long as no member of the
Telcom Ventures Group participates in the management of such entity. Under the
Intercompany Agreement, each of the Carlyle Investors (but not its affiliates)
has also agreed not to invest in any entity whose primary business is to compete
with the Company in its traditional business activities (excluding the program
management and towers businesses) until the earlier of (i) the date on which
such Carlyle Investor no longer owns directly or indirectly, an interest in the
Company or (ii) the occurrence of certain termination events specified in the
Formation Agreement.
 
     In consideration of the foregoing agreements of the Telcom Ventures Group,
the Company has agreed that, if any opportunity to invest in or acquire a third
party the value of which could reasonably be deemed to exceed $1 million (an
"Investment Opportunity") is presented to the Company that it wishes to refer to
a third party, the Company must give written notice to Telcom Ventures of such
Investment Opportunity. Telcom Ventures has five business days following its
receipt of the notice to inform the Company of its desire to pursue the
Investment Opportunity. If Telcom Ventures does not wish to pursue the
Investment Opportunity, or fails to provide timely notice to the Company of its
interest, the Company may refer the Investment Opportunity to any third party.
 
  Advances To and From Telcom Ventures and Related Parties
 
     Immediately following the Offering, the Company made a loan of $3.5 million
to Telcom Ventures from proceeds of the Offering to assist Telcom Ventures in
paying certain taxes due in connection with the MCI Note Assumption (as defined
below). The loan is repayable over five years, with equal annual principal
payments over the term of the loan. Interest accrues at the rate of LIBOR plus
1.75% and is payable annually. The loan constitutes senior indebtedness of
Telcom Ventures. Upon the sale by Telcom Ventures or any of its affiliates
(defined as each entity controlling, controlled by or under common control with,
Telcom Ventures, each natural person that controls Telcom Ventures and each
member of Telcom Ventures as of the date of the loan) of shares of Common Stock
resulting in Telcom Ventures and such affiliates, in the aggregate, owning less
than 25% of the outstanding Common Stock, the Company may declare the loan to be
due and payable. In each of November 1997 and October 1998, the Company received
payments of approximately $1.0 million from Telcom Ventures representing payment
of $0.7 million in principal and approximately $0.3 million in interest under
the terms of this note.
 
     On January 28, 1999, the Company entered into a $5.0 million convertible
promissory note with Telcom Ventures. Under the terms of the note, the entire
principal balance and accrued interest at a rate of 9% per annum is due on April
30, 2000, or upon the occurrence of certain events such as the sale of all or
substantially
                                       19
<PAGE>   23
 
all of the assets of the Company. At anytime from August 1, 1999, either Telcom
Ventures or the Company may convert the then outstanding principal and accrued,
but unpaid, interest into shares of Class A Common stock of the Company based on
a conversion price of $6.22 per share, subject to adjustment for stock split,
stock dividend, recapitalization or other events. Payments of principal under
the promissory note are subordinated to payments by the Company under its
amended and restated credit facility with The Chase Manhattan Bank (the "Credit
Facility").
 
  Guaranty of the Credit Facility
 
     Dr. Rajendra Singh has guaranteed the payment and performance obligations
of the Company under the Credit Facility, up to a maximum amount of $12.5
million plus interest thereon. The Credit Facility consists of a revolving loan
and letter of credit facility in an aggregate principal amount not to exceed $20
million for the Company and $2.5 million for the Company's subsidiary, LCC
Europe AS. The maximum amount available for drawing under the Credit Facility is
the sum of (i) the lesser of $10 million or 85% of the amount of the Company's
receivables which are deemed "eligible" as a basis for obtaining credit and (ii)
an aggregate amount, not to exceed $12.5 million, to the extent that Dr.
Rajendra Singh has deposited specified collateral with the lenders. Dr. Singh is
not contractually committed to provide any such collateral.
 
  Credit Support
 
     In March, 1999, Telcom Ventures signed a letter stating its intent to
provide the Company with funding to cover any cash shortfalls the Company may
have during 1999, in an amount not to exceed $12.5 million less the sum of
amounts drawn under the Credit Facility in excess of $10 million plus amounts
received through additional financings or the sale of the Company's products
businesses. This assurance is subject to the satisfaction of certain conditions,
including reaching agreement with the Company on applicable financing documents,
and will apply only as long as Telcom Ventures directly or indirectly owns at
least 40% of the Company's outstanding common stock, other than stock issued to
MCI upon conversion of notes issued to MCI into Class A Common Stock (see
"Certain Relationships and Related Transactions," below).
 
  Registration Rights
 
     Concurrently with the Offering, the Company, RF Investors and MCI entered
into a Registration Rights Agreement relating to the Class A Common Stock
issuable upon conversion of Class B Common Stock or upon conversion of the
outstanding indebtedness of the Company to MCI. Under the Registration Rights
Agreement, RF Investors and MCI have certain "demand" rights to require the
Company to register their Common Stock for sale and may register shares on a
"piggyback" basis in connection with most registered public offerings of
securities of the Company.
 
  Provision of Services and Products to Telcom Ventures and Parties Related
Thereto
 
     The Company provides engineering services and software products to Telcom
Ventures and various other companies owned, in part, by Telcom Ventures or its
members. On October 5, 1998, the Company and Telcom Ventures entered into a
Software License Agreement. In 1998, Telcom Ventures paid the Company $400,000
under the Software License Agreement and $200,000 under a services agreement.
Revenues earned during 1997 and 1998 for such services and products were
approximately $1.5 million and $750,000, respectively. Trade accounts receivable
from these related parties for the services and products were $811,000 at
December 31, 1997 and $164,000 at December 31, 1998.
 
     Concurrently with the Offering, the Company and Telcom Ventures entered
into an Overhead and Administrative Services Agreement. Pursuant to the Overhead
and Administrative Services Agreement, certain management personnel and other
employees of the Company provide certain administrative services, principally
related to human resource management functions and, until the first quarter of
1997, to administration of accounts payable and accounts receivable systems and
provisions of general office support services, to Telcom Ventures and, until the
first quarter of 1998, Telcom Ventures subleased office space from the Company.
Telcom Ventures is obligated to pay the Company a monthly fee for such
administrative
 
                                       20
<PAGE>   24
 
services and office space based on a reasonable estimate of the Company's cost
of providing same. While this agreement is not the result of arm's length
negotiations, it is designed to reimburse the Company for its costs in providing
such services (including costs of personnel), and the Company believes that the
terms of such agreements are reasonable. Telcom Ventures paid the Company
approximately $115,000 in January 1997 and approximately $85,000 in March 1998
pursuant to the Overhead and Administrative Services Agreement.
 
COMPARATIVE STOCK PERFORMANCE
 
     The following chart sets forth comparative information regarding the
Company's cumulative stockholder return on its Class A Common Stock since its
initial public offering completed in September 1996. Total stockholder return is
measured by dividing total dividends (assuming dividend reinvestment) plus share
price change for a period by the share price at the beginning of the measurement
period. The Company's cumulative stockholder return based on an investment of
$100 at September 25, 1996 when the Company's Class A Common Stock was first
traded on the Nasdaq National Market at its closing price of $20.25 is compared
to the cumulative total return of the Nasdaq Market Index and an index comprised
of publicly traded companies which are principally in the consulting and/or
telecommunications products and services business (the "Companies") during that
same period. As of December 31, 1998, the Companies that constituted the peer
group consisted of: Computer Sciences Corporation, Alternative Resources
Corporation, American Management Systems, Incorporated, Computer Horizons Corp.,
Technology Solutions Company, Ciber, Inc., Allen Telecom Inc. and Salient 3
Communications Inc.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
     The following is a summary of certain transactions and relationships among
the Company and its associated entities, and among the directors, executive
officers and stockholders of the Company and its associated entities. For a
description of certain other transactions, see "Compensation Committee
Interlocks."
 
  The Merger
 
     Pursuant to the Merger, the Company is required to indemnify Telcom
Ventures, RF Investors, Cherrywood, the Carlyle Investors and TC Group against
any liability for obligations and liabilities associated with the Limited
Liability Company's operations.
 
  Carlyle Option Designee Stock Options
 
     The Company has reserved 85,000 shares of Class A Common Stock (subject to
anti-dilution adjustments in the event of a stock split, recapitalization or
similar transaction) for issuance pursuant to options to be granted to a
designee of the Carlyle Investors (the "Carlyle Option Designee Stock Options").
The option exercise price for the Carlyle Option Designee Stock Options will be
100% of the fair market value of the Class A Common Stock on the date of grant
of the option. TC Group was granted an initial option to purchase 25,000 shares
of Class A Common Stock in connection with the Offering. A TC Group designee was
granted a further option to purchase 15,000 shares of Class A Common Stock on
September 24, 1997 at an exercise price of $20.125. The September 24, 1997
options vested immediately and are for a term of five years. TC Group or one or
more other designees of the Carlyle Investors were granted an additional option
to purchase 15,000 shares of Class A Common Stock on September 24, 1998, and
will be granted an additional
 
                                       22
<PAGE>   26
 
option to purchase 15,000 shares of Class A Common Stock on each of September
24, 1999 and 2000. Options granted vested immediately. The options will expire
no later than the fifth anniversary of the date of grant.
 
  The Exchangeable Notes, MCI Note Assumption, MCI Conversion
 
     In June 1994 the Limited Liability Company and Telcom Ventures entered into
a Note Purchase Agreement with a then unrelated third party, MCI, which provided
for the issuance of a $20 million subordinated note by the Limited Liability
Company (the "LCC Note") and of a $30 million subordinated note by Telcom
Ventures (the "Telcom Ventures Note") to MCI in return for cash in such amounts.
The LCC Note and the Telcom Ventures Note (collectively, the "Exchangeable
Notes") are exchangeable, at certain times, consisting of 45 day periods
commencing in June (at the option of MCI) and August (at the option of the
Company) of 1997, 1998, and 1999, into 2,841,099 shares of Class A Common Stock.
Payment under the Exchangeable Notes is subordinated to payment by the Company
under the Credit Facility (see "Compensation Committee and Interlocks and
Insider Participation," above).
 
     The Exchangeable Notes are both due June 28, 2000. The Exchangeable Notes
each bear interest at a rate equal to 4.4% per annum, payable semiannually.
Immediately prior to the Merger, the Telcom Ventures Note was assumed by the
Limited Liability Company (the "MCI Note Assumption"), and the $30 million
principal repayment obligation and interest thereon became the sole obligation
of the Limited Liability Company and, following the Merger, the sole obligation
of the Company.
 
     Since January 1, 1997, the Company has paid MCI approximately $2.2 million
in interest under the Exchangeable Notes. The Company is considering exercising
its option in August, 1999 to cause the Exchangeable Notes to be converted into
2,841,099 shares Class A Common Stock. This could result in a significant
taxable gain to the Company.
 
  Certain Relationships Between Cherrywood and the Carlyle Investors Affecting
the Company
 
     The RF Investors and Telcom Ventures limited liability company agreements
provide that, for as long as the Carlyle Investors collectively own at least 5%
of the total membership interests of Telcom Ventures, Telcom Ventures shall vote
any and all shares of the Company held by it, and shall cause RF Investors to
vote any and all shares held by it, from time to time: (i) to elect as directors
of the Company up to two persons recommended by the Carlyle Investors and (ii)
not take any of the following actions without the consent of the Carlyle
Investors: (a) approve any amendment to the Certificate of Incorporation or the
Bylaws of the Company; (b) approve the incurrence by the Company of any debt (or
the granting of security relating to the incurrence of debt) if as a result of
such incurrence, the debt to equity ratio of the Company exceeds 6:1, or, if as
a result of such debt incurrence, the total outstanding debt of the Company
exceeds $50 million plus or minus, as the case may be, the cumulative net income
or net losses of the Company after January 1994; (c) approve any new affiliated
party transactions in excess of $150,000 or of modifications to existing
transactions, subject to certain limited exceptions; (d) approve appointment of
independent accountants of the Company other than one of the "big five"
accounting firms; or (e) approve certain events relating to bankruptcy or
insolvency of the Company.
 
     The RF Investors and Telcom Ventures limited liability company agreements
provide for various rights of the Carlyle Investors to cause the distribution to
the Carlyle Investors of Common Stock held by RF Investors. Following the third
anniversary of the closing of the Offering, the Carlyle Investors will have the
right to cause the distribution to the Carlyle Investors (by RF Investors and
then Telcom Ventures), of up to the Carlyle Investors' indirect proportionate
interest in the shares of Common Stock then held by RF Investors which is in
excess of 10% of the Common Stock then outstanding (treating Class A Common
Stock and Class B Common Stock as a single class of Common Stock for this
purpose). The Carlyle Investors' initial indirect proportionate interest in RF
Investors is 25%, which interest will be recalculated following any
non-proportional distribution to the Carlyle Investors. Following the fifth
anniversary of the closing of the Offering, the Carlyle Investors will have the
right to cause the distribution to the Carlyle Investors (by RF Investors and
then Telcom Ventures), of up to the full amount of the Carlyle Investors' then
indirect proportionate interest in the shares of Common Stock, so long as the
Common Stock remaining held by RF
 
                                       23
<PAGE>   27
 
Investors would leave RF Investors with at least 51% of the voting power of the
Common Stock then outstanding. Upon the first distribution to the Carlyle
Investors, the Carlyle Investors will have the right to exercise one of the
three rights held by RF Investors to demand registration of shares of Common
Stock under the Securities Act of 1933. The ability of the Carlyle Investors to
require distributions of Class A Common Stock or demand a registration thereof
would be subject to a determination by an investment banker reasonably
acceptable to RF Investors and the Carlyle Investors that such action would not
materially adversely impact the market for the Common Stock.
 
SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
     Section 16(a) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), requires the Company's officers, directors and certain
beneficial holders of common stock to file reports about their ownership of the
Company's Class A Common Stock. Based solely on its review of the copies of such
reports furnished to the Company by its directors and officers during and with
respect to the year 1998, the Company is aware of no reports submitted on an
untimely basis.
 
         RATIFICATION OF APPOINTMENT OF INDEPENDENT PUBLIC ACCOUNTANTS
                                  (PROPOSAL 2)
 
     KPMG LLP (formerly KPMG Peat Marwick LLP) has been the Company's
independent auditor since the formation of the Limited Liability Company in
1994. The selection of KPMG LLP has been ratified by the stockholders in all
Annual Meetings since such engagement. The Company has selected KPMG LLP for the
current year, and has proposed that the stockholders of the Company ratify this
selection during the 1999 Annual Meeting. It is expected that representatives of
KPMG LLP will be present at the 1999 Annual Meeting to make a statement if they
so desire or to respond to appropriate questions.
 
     Unless otherwise instructed on the proxy, the persons named in the proxy to
vote the shares represented by each properly executed proxy shall vote for the
election as the principal accountant of the Company KPMG LLP.
 
 THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE RATIFICATION OF ITS SELECTION
                       OF INDEPENDENT PUBLIC ACCOUNTANT.

                  DATE OF SUBMISSION OF STOCKHOLDER PROPOSALS
                       TO BE INCLUDED IN PROXY MATERIALS
 
     Any proposal or proposal intended to be presented by any stockholder at the
2000 Annual Meeting of Stockholders must be received by the Company by January
24, 2000 to be considered for inclusion in the Company's proxy statement and
form of proxy relating to that meeting. Nothing in this paragraph shall be
deemed to require the Company to include in the proxy statement and the proxy
relating to the 2000 Annual Meeting of Stockholders any stockholder proposal
that does not meet all of the requirements for such inclusion in effect at that
time.
 
                        OTHER BUSINESS TO BE TRANSACTED
 
     As of the date of this proxy statement, the Board of Directors knows of no
other business which may come before the Annual Meeting. If any other business
is properly brought before the Annual Meeting, it is the intention of the proxy
holders to vote or act in accordance with their best judgment with respect to
such matters.
